Accurate segmentation of the liver and precise needle placement is essential for successful interventions such as needle aspiration. In this study, we propose a deep learning-based liver 3D slicer designed to enhance segmentation accuracy and facilitate needle aspiration procedures. The developed 3D slicer leverages state-of-the-art convolutional neural networks (CNNs) for automatic liver segmentation in medical images. The CNN model is trained on a diverse dataset of liver images obtained from various imaging modalities, including computed tomography (CT) and magnetic resonance imaging (MRI). The trained model demonstrates robust performance in accurately delineating liver boundaries, even in cases with anatomical variations and pathological conditions. Furthermore, the 3D slicer integrates advanced image registration techniques to ensure accurate alignment of preoperative images with real-time interventional imaging. This alignment enhances the precision of needle placement during aspiration procedures, minimizing the risk of complications and improving overall intervention outcomes. To validate the efficacy of the proposed deep learning-based 3D slicer, a comprehensive evaluation is conducted using a dataset of clinical cases. Quantitative metrics, including the Dice similarity coefficient and Hausdorff distance, are employed to assess the accuracy of liver segmentation. Additionally, the performance of the 3D slicer in guiding needle aspiration procedures is evaluated through simulated and clinical interventions. Preliminary results demonstrate the effectiveness of the developed 3D slicer in achieving accurate liver segmentation and guiding needle aspiration procedures with high precision. The integration of deep learning techniques into the IGT workflow shows great promise for enhancing the efficiency and safety of liver interventions, ultimately contributing to improved patient outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title="deep learning">deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20segmentation" title=" liver segmentation"> liver segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20slicer" title=" 3D slicer"> 3D slicer</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20guided%20therapy" title=" image guided therapy"> image guided therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=needle%20aspiration" title=" needle aspiration"> needle aspiration</a> </p> <a href="https://publications.waset.org/abstracts/183469/deep-learning-based-liver-3d-slicer-for-image-guided-therapy-segmentation-and-needle-aspiration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183469.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">48</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">268</span> Force Feedback Enabled Syringe for Aspiration and Biopsy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pelin%20Su%20Firat">Pelin Su Firat</a>, <a href="https://publications.waset.org/abstracts/search?q=Sohyung%20Cho"> Sohyung Cho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biopsy or aspiration procedures are known to be complicated as they involve the penetration of a needle through human tissues, including vital organs. This research presents the design of a force sensor-guided device to be used with syringes and needles for aspiration and biopsy. The development of the device was aimed to help accomplish accurate needle placement and increase the performance of the surgeon in navigating the tool and tracking the target. Specifically, a prototype for a force-sensor embedded syringe has been created using 3D (3-Dimensional) modeling and printing techniques in which two different force sensors were used to provide significant force feedback to users during the operations when needles pernitrate different tissues. From the extensive tests using synthetic tissues, it is shown that the proposed syringe design has accomplished the desired accuracy, efficiency, repeatability, and effectiveness. Further development is desirable through usability tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biopsy" title="biopsy">biopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=syringe" title=" syringe"> syringe</a>, <a href="https://publications.waset.org/abstracts/search?q=force%20sensors" title=" force sensors"> force sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=haptic%20feedback" title=" haptic feedback"> haptic feedback</a> </p> <a href="https://publications.waset.org/abstracts/183278/force-feedback-enabled-syringe-for-aspiration-and-biopsy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183278.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">67</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">267</span> The Usefulness and Limitations of Manual Aspiration Immediately after Pneumothorax Complicating Percutaneous CT Guided Lung Biopsies: A Retrospective 9-Year Review from a Large Tertiary Centre</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niall%20Fennessy">Niall Fennessy</a>, <a href="https://publications.waset.org/abstracts/search?q=Charlotte%20Yin"> Charlotte Yin</a>, <a href="https://publications.waset.org/abstracts/search?q=Vineet%20Gorolay"> Vineet Gorolay</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Chan"> Michael Chan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilias%20Drivas"> Ilias Drivas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The aim of this study was to evaluate the effect of manual aspiration of air from the pleural cavity in mitigating the need for chest drain placement after a CT-guided lung biopsy. Method: This is a single institution retrospective review of CT-guided lung biopsies performed on 799 patients between September 2013 and May 2021 in a major tertiary hospital. Percutaneous manual aspiration of air was performed in 104/306 patients (34%) with pneumothoraxes as a preventative measure. Simple and multivariate analysis was performed to identify independent risk factors (modifiable and nonmodifiable) for the success of manual aspiration in mitigating the need for chest drain insertion. Results: The overall incidence of pneumothorax was 37% (295/799). Chest drains were inserted for 81/295 (27%) of the pneumothoraxes, representing 81/799 (10%) of all CT-guided lung biopsies. Of patients with pneumothoraces, 104 (36%) underwent percutaneous aspiration via either the coaxial guide needle or an 18 or 20G intravenous catheter attached to a three-way stopcock and syringe. Amongst this group, 13 patients (13%) subsequently required chest drain insertion. The success of percutaneous aspiration in avoiding subsequent pleural drain insertion decreased with aspiration volume >500mL, radial pneumothorax depth >3cm, increased subpleural depth of the lesion, and the presence of background emphysema. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computed%20tomography" title="computed tomography">computed tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20biopsy" title=" lung biopsy"> lung biopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=pneumothorax" title=" pneumothorax"> pneumothorax</a>, <a href="https://publications.waset.org/abstracts/search?q=manual%20aspiration" title=" manual aspiration"> manual aspiration</a>, <a href="https://publications.waset.org/abstracts/search?q=chest%20drainage" title=" chest drainage"> chest drainage</a> </p> <a href="https://publications.waset.org/abstracts/140907/the-usefulness-and-limitations-of-manual-aspiration-immediately-after-pneumothorax-complicating-percutaneous-ct-guided-lung-biopsies-a-retrospective-9-year-review-from-a-large-tertiary-centre" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140907.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">175</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">266</span> Evolving Digital Circuits for Early Stage Breast Cancer Detection Using Cartesian Genetic Programming</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Khalid">Zahra Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Gul%20Muhammad%20Khan"> Gul Muhammad Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Arbab%20Masood%20Ahmad"> Arbab Masood Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cartesian Genetic Programming (CGP) is explored to design an optimal circuit capable of early stage breast cancer detection.

In the present study, we evaluated diagnostic accuracy of Fine needle aspiration (FNA) and its efficiency in early detecting neoplastic lesions of thyroid gland over a 3-year period. Methods: Data have been retrieved from pathology files in King Khalid Hospital. For each patient, age, gender, FNA, site & size of nodule and final histopathologic diagnosis were recorded. Results: Study included 490 cases where 419 of them were female and 71 male. Male to female ratio was 1:6. Mean age was 43 years for males and 38 for females. Cases with confirmed histopathology were 131. In 101/131 (77.1%), concordance was found between FNA and histology. In 30/131 (22.9%), there was discrepancy in diagnosis. Total malignant cases were 43, out of which 14 (32.5%) were true positive and 29 (67.44%) were false negative. No false positive cases could be found in our series. Conclusion: FNA could diagnose benign nodules in all cases, however, in malignant cases, ultrasound findings have to be taken into consideration to avoid missing of a microcarcinoma in the contralateral lobe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FNA" title="FNA">FNA</a>, <a href="https://publications.waset.org/abstracts/search?q=hail" title=" hail"> hail</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a>, <a href="https://publications.waset.org/abstracts/search?q=thyroid" title=" thyroid"> thyroid</a> </p> <a href="https://publications.waset.org/abstracts/72692/a-3-year-evaluation-study-on-fine-needle-aspiration-cytology-and-corresponding-histology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72692.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">335</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">263</span> Saline Aspiration Negative Intravascular Test: Mitigating Risk with Injectable Fillers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Lopes%20Dias%20Kolling">Marcelo Lopes Dias Kolling</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Ferreira%20Laranjeira"> Felipe Ferreira Laranjeira</a>, <a href="https://publications.waset.org/abstracts/search?q=Guilherme%20Augusto%20Hettwer"> Guilherme Augusto Hettwer</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Salom%C3%A3o%20Piccinini"> Pedro Salomão Piccinini</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwan%20Masri"> Marwan Masri</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Oscar%20Uebel"> Carlos Oscar Uebel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Injectable fillers are among the most common nonsurgical cosmetic procedures, with significant growth yearly. Knowledge of rheological and mechanical characteristics of fillers, facial anatomy, and injection technique is essential for safety. Concepts such as the use of cannula versus needle, aspiration before injection, and facial danger zones have been well discussed. In case of an accidental intravascular puncture, the pressure inside the vessel may not be sufficient to push blood into the syringe due to the characteristics of the filler product; this is especially true for calcium hydroxyapatite (CaHA) or hyaluronic acid (HA) fillers with high G’. Since viscoelastic properties of normal saline are much lower than those of fillers, aspiration with saline prior to filler injection may decrease the risk of a false negative aspiration and subsequent catastrophic effects. We discuss a technique to add an additional safety step to the procedure with saline aspiration prior to injection, a ‘’reverse Seldinger’’ technique for intravascular access, which we term SANIT: Saline Aspiration Negative Intravascular Test. Objectives: To demonstrate the author’s (PSP) technique which adds an additional safety step to the process of filler injection, with both CaHA and HA, in order to decrease the risk of intravascular injection. Materials and Methods: Normal skin cleansing and topical anesthesia with prilocaine/lidocaine cream are performed; the facial subunits to be treated are marked. A 3mL Luer lock syringe is filled with 2mL of 0.9% normal saline and a 27G needle, which is turned one half rotation. When a cannula is to be used, the Luer lock syringe is attached to a 27G 4cm single hole disposable cannula. After skin puncture, the 3mL syringe is advanced with the plunger pulled back (negative pressure). Progress is made to the desired depth, all the while aspirating. Once the desired location of filler injection is reached, the syringe is exchanged for the syringe containing a filler, securely grabbing the hub of the needle and taking care to not dislodge the needle tip. Prior to this, we remove 0.1mL of filler to allow for space inside the syringe for aspiration. We again aspirate and inject retrograde. SANIT is especially useful for CaHA, since the G’ is much higher than HA, and thus reflux of blood into the syringe is less likely to occur. Results: The technique has been used safely for the past two years with no adverse events; the increase in cost is negligible (only the cost of 2mL of normal saline). Over 100 patients (over 300 syringes) have been treated with this technique. The risk of accidental intravascular puncture has been calculated to be between 1:6410 to 1:40882 syringes among expert injectors; however, the consequences of intravascular injection can be catastrophic even with board-certified physicians. Conclusions: While the risk of intravascular filler injection is low, the consequences can be disastrous. We believe that adding the SANIT technique can help further mitigate risk with no significant untoward effects and could be considered by all performing injectable fillers.

It is hypothesized that given these morphological similarities, the genome of mycobacterium could have an impact on the development of Sarcoidosis. Identifying the potential correlation of these diseases may assist in the management of sarcoidosis. Herein, we aimed to inspect the lymph node biopsy of sarcoidosis patients for the existence of the HSP-65 mycobacterium DNA sequence. Methods: This cross-sectional survey was conducted on 1188 Sarcoidosis patients without active/latent tuberculosis infection who were diagnosed in Masih Daneshvari Hospital in Tehran, Iran, from January 2020 to January 2022. Trans-bronchial needle aspiration (TBNA) was performed due to bilateral hilar lymphadenopathy to take a specimen. Results: The under-evaluated patients were mainly women (N=815 (68.6%)), none-smoker (N=1016 (85.5%)), and middle-aged (50.1 (SD=4.22)) with average angiotensin-converting enzyme (ACE) index of 75.6 (SD=6.42). Dyslipidemias (n=314 (26.4%), Hypertension (n=295 (24.8%)), Diabetes mellitus (n=131 (11.0%)), and chronic heart diseases (n=97 (8.2%)) had the highest prevalence between comorbidities. Skin lesions (n= 655 (55.1%)), ophthalmic (n=341 (28.7%)), and cardiac involvement (n=229 (19.3%)) were obtained as the most common extra-pulmonary characteristics of the patients. Amongst 1188 enrolled patients who were not afflicted with Mycobacterium tuberculosis based on smear/culture essay, clinical symptoms, and Chest x-ray screening, 121 (10.2%) cases had detectable amplified DNA for Mycobacterium Tuberculosis extracted from mediastinal lung lymph nodes. Conclusion: In this survey, the mycobacterium genome was detected in almost 1 per 10 case biopsies of sarcoidosis. The remarkable number of cases (n=1188) evaluated in this study was the strength of this study which supported the hypothesis regarding sarcoidosis and mycobacterium genome correlation. Further investigation, such as case-control surveys, is required to better clarify this association. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mycobacterium%20tuberculosis" title="mycobacterium tuberculosis">mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=sarcoidosis" title=" sarcoidosis"> sarcoidosis</a>, <a href="https://publications.waset.org/abstracts/search?q=genome" title=" genome"> genome</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA" title=" DNA"> DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=trans-bronchial%20needle%20aspiration" title=" trans-bronchial needle aspiration"> trans-bronchial needle aspiration</a> </p> <a href="https://publications.waset.org/abstracts/187424/mycobacterium-genome-extraction-from-lymph-nodes-of-sarcoidosis-cases-using-transbronchial-needle-aspiration-a-cross-sectional-descriptive-essay-on-1223-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187424.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">31</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">261</span> Rethinking the Value of Pancreatic Cyst CEA Levels from Endoscopic Ultrasound Fine-Needle Aspiration (EUS-FNA): A Longitudinal Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giselle%20Tran">Giselle Tran</a>, <a href="https://publications.waset.org/abstracts/search?q=Ralitza%20Parina"> Ralitza Parina</a>, <a href="https://publications.waset.org/abstracts/search?q=Phuong%20T.%20Nguyen"> Phuong T. Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background/Aims: Pancreatic cysts (PC) have recently become an increasingly common entity, often diagnosed as incidental findings on cross-sectional imaging. Clinically, management of the lesions is difficult because of uncertainties in their potential for malignant degeneration. Prior series have reported that carcinoembryonic antigen (CEA), a biomarker collected from cyst fluid aspiration, has a high diagnostic accuracy for discriminating between mucinous and non-mucinous lesions, at the patient’s initial presentation. To the author’s best knowledge, no prior studies have reported PC CEA levels obtained from endoscopic ultrasound fine-needle aspiration (EUS-FNA) over years of serial EUS surveillance imaging. Methods: We report a consecutive retrospective series of 624 patients who underwent EUS evaluation for a PC between 11/20/2009 and 11/13/2018. Of these patients, 401 patients had CEA values obtained at the point of entry. Of these, 157 patients had two or more CEA values obtained over the course of their EUS surveillance. Of the 157 patients (96 F, 61 M; mean age 68 [range, 62-76]), the mean interval of EUS follow-up was 29.7 months [3.5-128]. The mean number of EUS procedures was 3 [2-7]. To assess CEA value fluctuations, we defined an appreciable increase in CEA as "spikes" – two-times increase in CEA on a subsequent EUS-FNA of the same cyst, with the second CEA value being greater than 1000 ng/mL. Using this definition, cysts with a spike in CEA were compared to those without a spike in a bivariate analysis to determine if a CEA spike is associated with poorer outcomes and the presence of high-risk features. Results: Of the 157 patients analyzed, 29 had a spike in CEA. Of these 29 patients, 5 had a cyst with size increase >0.5cm (p=0.93); 2 had a large cyst, >3cm (p=0.77); 1 had a cyst that developed a new solid component (p=0.03); 7 had a cyst with a solid component at any time during surveillance (p=0.08); 21 had a complex cyst (p=0.34); 4 had a cyst categorized as "Statistically Higher Risk" based on molecular analysis (p=0.11); and 0 underwent surgical resection (p=0.28). Conclusion: With serial EUS imaging in the surveillance of PC, an increase in CEA level defined as a spike did not predict poorer outcomes. Most notably, a spike in CEA did not correlate with the number of patients sent to surgery or patients with an appreciable increase in cyst size. A spike in CEA did not correlate with the development of a solid nodule within the PC nor progression on molecular analysis. Future studies should focus on the selected use of CEA analysis when patients undergo EUS surveillance evaluation for PCs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carcinoembryonic%20antigen%20%28CEA%29" title="carcinoembryonic antigen (CEA)">carcinoembryonic antigen (CEA)</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20ultrasound%20%28EUS%29" title=" endoscopic ultrasound (EUS)"> endoscopic ultrasound (EUS)</a>, <a href="https://publications.waset.org/abstracts/search?q=fine-needle%20aspiration%20%28FNA%29" title=" fine-needle aspiration (FNA)"> fine-needle aspiration (FNA)</a>, <a href="https://publications.waset.org/abstracts/search?q=pancreatic%20cyst" title=" pancreatic cyst"> pancreatic cyst</a>, <a href="https://publications.waset.org/abstracts/search?q=spike" title=" spike"> spike</a> </p> <a href="https://publications.waset.org/abstracts/148012/rethinking-the-value-of-pancreatic-cyst-cea-levels-from-endoscopic-ultrasound-fine-needle-aspiration-eus-fna-a-longitudinal-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148012.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">260</span> Endoscopic Ultrasound Guided Fine Needle Aspiration/Brush in Cytopathology Diagnosis: A Fifteen-Month Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santosh%20Tummidi">Santosh Tummidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Pragati%20Sathe"> Pragati Sathe</a>, <a href="https://publications.waset.org/abstracts/search?q=Kanchan%20Kothari"> Kanchan Kothari</a>, <a href="https://publications.waset.org/abstracts/search?q=Prachi%20Gholap"> Prachi Gholap</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Agnihotri"> Mona Agnihotri</a>, <a href="https://publications.waset.org/abstracts/search?q=Gwendolyn%20Fernandes"> Gwendolyn Fernandes</a>, <a href="https://publications.waset.org/abstracts/search?q=Leena%20Naik"> Leena Naik</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachana%20Chaturvedi"> Rachana Chaturvedi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: EUS-Guided Fine Needle Aspiration/Brush (EUS-FNA/Brush) has become increasingly popular for the diagnosis and staging of gastrointestinal and peri-gastrointestinal lesions. Objective: To evaluate the diagnostic accuracy and spectrum of lesions in gastrointestinal EUS-FNA. Material and Methods: A total of 124 EUS-FNA during the period from Aug 2015-Nov 2016 were studied. Results: Age ranged from 13-80 years with a slight female predominance. CBD was the most common site with 47 cases amongst which were 9 adenocarcinoma, and 7 cases were suspicious for malignancy. Pancreatic EUS-FNA showed 5 adenocarcinoma, 2 SPEN, 1 case each of neuroendocrine tumor, anaplastic carcinoma and NHL. Amongst oesophageal lesions, 3 cases were suspicious for malignancy, and 4 were inflammatory, 4 showed SCC, 1case each adenocarcinoma and leiomyoma. Stomach- 1 case each of adenocarcinoma, granulomatous inflammation, and GIST. Periportal lymph nodes were the commonest nodes, and there were 11 necrotising granulomatous inflammations, 3 metastatic adenocarcinoma, 2 cases of atypical cells and 1 case of NHL. 17 cases were unsatisfactory, 41 cases had histopathology follow up with 85% cases being concordant. Conclusion: EUS-FNA is reliable, sensitive and specific. It can be utilized for better management of intra-abdominal lesions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EUS-FNA" title="EUS-FNA">EUS-FNA</a>, <a href="https://publications.waset.org/abstracts/search?q=brush" title=" brush"> brush</a>, <a href="https://publications.waset.org/abstracts/search?q=cytology" title=" cytology"> cytology</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a> </p> <a href="https://publications.waset.org/abstracts/69355/endoscopic-ultrasound-guided-fine-needle-aspirationbrush-in-cytopathology-diagnosis-a-fifteen-month-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69355.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">304</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">259</span> Fine Needle Aspiration Biopsy of Thyroid Nodules</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ilirian%20La%C3%A7i">Ilirian Laçi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alketa%20Spahiu"> Alketa Spahiu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Big strums of thyroid glandule observed by a simple viewing can be witnessed in everyday life. Medical cabinets evidence patients withpalpablenodes of thyroid glandule, mainly nodes of the size of 10 millimeters. Further, more cases which have resulted in negative under palpation have resulted in positive at ultrasound examination. Therefore, the use of ultrasound for diagnosing has increased the number of patients with nodes of thyroid glandule in the last couple of decades in all countries, Albania included. Thus, there has been evidence of an increased number of patients affected by this pathology, where female patients dominate. Demographically, the capital shows high numbers due to the high population, but of interest is the high incidence of those areas distanced from the sea. While regarding related pathologies, no significant link was evidenced, an element of ancestry was evident in the nodes of the thyroid glandule. When we talk of nodes of the thyroid glandule, we should consider hyperplasia, neoplasia, and inflammatory diseases that cause nodes of the thyroid glandule. This increase parallels the world’s increase of the incidence of thyroid glandule, with malign cases, which are at about 5% and are not depended on size. Given the numbers, with most thyroid glandule nodes being benign, the main objective of the examination of the nodes was the determination of benign and malign cases to avoid undue surgery. Subject of this study were 212 patients that underwent fine-needle aspiration (FNA) under ultrasound guidance at the Medical University Center of Tirana. All the patients came to the Mother Teresa University Hospital from public and private hospitals and other polyclinics. These patients had an ultrasound examination before visiting the Center of Nuclear Medicine for a scintigraph of thyroid glandule in the period September 2016 and September 2017. To correlate, all patients had been examined via ultrasound of the thyroid glandule prior to the scintigraph. The ultrasound included evaluation of the number of nodes, their size, their solid, cystic, or solid-cystic structure, echogenicity according to the gray scale, the presence of calcification, the presence of lymph nodes, the presence of adenopathy, and the correlation of the cytology results from the Laboratory of Pathological Anatomy of Medical University Center of Tirana. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thyroid%20nodes" title="thyroid nodes">thyroid nodes</a>, <a href="https://publications.waset.org/abstracts/search?q=fine%20needle%20aspiration" title=" fine needle aspiration"> fine needle aspiration</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=scintigraphy" title=" scintigraphy"> scintigraphy</a> </p> <a href="https://publications.waset.org/abstracts/152501/fine-needle-aspiration-biopsy-of-thyroid-nodules" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152501.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">258</span> Needle Track Technique In Strabismus Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seema%20Dutt%20Bandhu">Seema Dutt Bandhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yashi%20Bansal"> Yashi Bansal</a>, <a href="https://publications.waset.org/abstracts/search?q=Tania%20Moudgil"> Tania Moudgil</a>, <a href="https://publications.waset.org/abstracts/search?q=Barinder%20Kaur"> Barinder Kaur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Scleral perforation during the passage of suture needle is a known complication of strabismus surgery. The present study was conducted to evolve a safe and easy technique of passing the suture needle through the sclera. A scleral tunnel was created with a 26-guage needle through which the suture needle was passed. The rest of the steps of strabismus surgery were carried out as usual. Material and Methods: After taking clearance from the Institutional Ethics Committee, an interventional study was carried out on twenty patients. The scleral tunnel technique was performed on the patients of strabismus after taking written informed consent. Before passing the suture needle through the sclera during strabismus surgery, a tunnel through approximately half the thickness of the sclera was created with the help of a bent 26-gauge needle. The suture needle was then passed through this tunnel. Rest of the steps of the surgery were carried out in the conventional manner. In a control group of same number of patients, the surgery was performed in the conventional method. Both the groups were followed up for any complications. Ease of passing suture and surgeons’ satisfaction with the technique was noted on a 10-point Likert scale. Results: None of the patients in either group suffered from any complications. Four surgeons participated in the study. The average Likert scale score of the surgeons for satisfaction with the technique was 4.5 on a scale of 5. The score for ease of passage of suture needle was 5 on a score of 5. Discussion: Scleral perforation during passing the sutures through the sclera is a known complication of strabismus surgery. Incidence reported is 7.8% It occurs due to inappropriate engagement of the scleral tissue or passage of the suture needle along a wrong axis during the process of passing the suture needle. The needle track technique eases the passage of passing the suture needle through the sclera as the engagement of the scleral tissue can be done with greater control with a 26-guage needle. The surgeons have reported that they are highly satisfied with the technique and they have reported that the technique eased the passage of the suture needle through the sclera. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=suture" title="suture">suture</a>, <a href="https://publications.waset.org/abstracts/search?q=scleral%20tunnel" title=" scleral tunnel"> scleral tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=strabismus" title=" strabismus"> strabismus</a>, <a href="https://publications.waset.org/abstracts/search?q=scleral%20perforation" title=" scleral perforation"> scleral perforation</a> </p> <a href="https://publications.waset.org/abstracts/164236/needle-track-technique-in-strabismus-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164236.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">257</span> The Utility of Sonographic Features of Lymph Nodes during EBUS-TBNA for Predicting Malignancy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atefeh%20Abedini">Atefeh Abedini</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Razavi"> Fatemeh Razavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mihan%20Pourabdollah%20Toutkaboni"> Mihan Pourabdollah Toutkaboni</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Mehravaran"> Hossein Mehravaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Arda%20Kiani"> Arda Kiani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In countries with the highest prevalence of tuberculosis, such as Iran, the differentiation of malignant tumors from non-malignant is very important. In this study, which was conducted for the first time among the Iranian population, the utility of the ultrasonographic morphological characteristics in patients undergoing EBUS was used to distinguish the non-malignant versus malignant lymph nodes. The morphological characteristics of lymph nodes, which consist of size, shape, vascular pattern, echogenicity, margin, coagulation necrosis sign, calcification, and central hilar structure, were obtained during Endobronchial Ultrasound-Guided Trans-Bronchial Needle Aspiration and were compared with the final pathology results. During this study period, a total of 253 lymph nodes were evaluated in 93 cases. Round shape, non-hilar vascular pattern, heterogeneous echogenicity, hyperechogenicity, distinct margin, and the presence of necrosis sign were significantly higher in malignant nodes. On the other hand, the presence of calcification and also central hilar structure were significantly higher in the benign nodes (p-value ˂ 0.05). Multivariate logistic regression showed that size>1 cm, heterogeneous echogenicity, hyperechogenicity, the presence of necrosis signs and, the absence of central hilar structure are independent predictive factors for malignancy. The accuracy of each of the aforementioned factors is 42.29 %, 71.54 %, 71.90 %, 73.51 %, and 65.61 %, respectively. Of 74 malignant lymph nodes, 100% had at least one of these independent factors. According to our results, the morphological characteristics of lymph nodes based on Endobronchial Ultrasound-Guided Trans-Bronchial Needle Aspiration can play a role in the prediction of malignancy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EBUS-TBNA" title="EBUS-TBNA">EBUS-TBNA</a>, <a href="https://publications.waset.org/abstracts/search?q=malignancy" title=" malignancy"> malignancy</a>, <a href="https://publications.waset.org/abstracts/search?q=nodal%20characteristics" title=" nodal characteristics"> nodal characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=pathology" title=" pathology"> pathology</a> </p> <a href="https://publications.waset.org/abstracts/113826/the-utility-of-sonographic-features-of-lymph-nodes-during-ebus-tbna-for-predicting-malignancy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113826.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">135</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">256</span> Histological Grade Concordance between Core Needle Biopsy and Corresponding Surgical Specimen in Breast Carcinoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Szpor">J.

In comparison to fine needle aspiration (FNA), CNB provides more architectural information allowing for the evaluation of prognostic and predictive factors for breast cancer, including histological grade—one of three prognostic factors used to calculate the Nottingham Prognostic Index. Several studies have previously described the concordance rate between CNB and surgical excision specimen in determination of histological grade (HG). The concordance rate previously ascribed to overall grade varies widely across literature, ranging from 59-91%. The aim of this study is to see how the data looks like in material at authors’ institution and are the results as compared to those described in previous literature. The study population included 157 women with a breast tumor who underwent a core needle biopsy for breast carcinoma and a subsequent surgical excision of the tumor. Both materials were evaluated for the determination of histological grade (scale from 1 to 3). HG was assessed only in core needle biopsies containing at least 10 well preserved HPF with invasive tumor. The degree of concordance between CNB and surgical excision specimen for the determination of tumor grade was assessed by Cohen’s kappa coefficient. The level of agreement between core needle biopsy and surgical resection specimen for overall histologic grading was 73% (113 of 155 cases). CNB correctly predicted the grade of the surgical excision specimen in 21 cases for grade 1 tumors (Kappa coefficient κ = 0.525 95% CI (0.3634; 0.6818), 52 cases for grade 2 (Kappa coefficient κ = 0.5652 95% CI (0.458; 0.667) and 40 cases for stage 3 tumors (Kappa coefficient κ = 0.6154 95% CI (0.4862; 0.7309). The highest level of agreement was observed in grade 3 malignancies. In 9 of 42 (21%) discordant cases, the grade was higher in the CNB than in the surgical excision. This composed 6% of the overall discordance. These results correspond to the noted in the literature, showing that underestimation occurs more frequently than overestimation. This study shows that authors’ institution’s histologic grading of CNBs and surgical excisions shows a fairly good correlation and is consistent with findings in previous reports. Despite the inevitable limitations of CNB, CNB is an effective method for diagnosing breast cancer and managing treatment options. Assessment of tumour grade by CNB is useful for the planning of treatment, so in authors’ opinion it is worthy to implement it in daily practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=concordance" title=" concordance"> concordance</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20needle%20biopsy" title=" core needle biopsy"> core needle biopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=histological%20grade" title=" histological grade"> histological grade</a> </p> <a href="https://publications.waset.org/abstracts/136072/histological-grade-concordance-between-core-needle-biopsy-and-corresponding-surgical-specimen-in-breast-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136072.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">229</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">255</span> A Portable Miniature Syringe Needle Remover And Receptacle For Drug Injection Users</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fanjun%20Zhou">Fanjun Zhou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In today's drug-ridden society, drug injection is gradually becoming more popular and has hidden danger to IDUs (injection drug users) such as infectious diseases. According to reports, 67% of IDUs reported improper disposal at some point over the prior 30 days, leading to a proliferation of injection needles on the streets. In recent years, the number of cases of children or ordinary people unintentionally picking up needles have increased. Various needle remover inventions have begun to surface, but the existing ones are either expensive, unportable, or risky for IDUs. In order to effectively alleviate the proliferation of drug injection needles and improve the invention of needle removers, a miniature portable needle remover and receptacle is invented. The device for capturing and storing syringe needles contains an upper lid portion mounted tightly onto the lower box portion through an interlock system on the opposing sides of the device with a breaking-twisting mechanism to remove the needle. The invention is intended to be affordable to the general public, safe enough for IDUs to use, reliable enough not to harm others, and effective in breaking needles from the syringe. This report is conducted in the hope of spreading awareness of the dangers of drug injection and to provide a way to mitigate this drug rampant situation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=needle%20remover" title="needle remover">needle remover</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20injection" title=" drug injection"> drug injection</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20drug%20users" title=" injection drug users"> injection drug users</a>, <a href="https://publications.waset.org/abstracts/search?q=portable" title=" portable"> portable</a>, <a href="https://publications.waset.org/abstracts/search?q=receptacle" title=" receptacle"> receptacle</a> </p> <a href="https://publications.waset.org/abstracts/154602/a-portable-miniature-syringe-needle-remover-and-receptacle-for-drug-injection-users" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154602.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">254</span> The French, the Yoruba, and the H-Thing: Sharing and Realising Same Phenomenon Differently</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rose-Juliet%20Anyanwu">Rose-Juliet Anyanwu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The principal objective of this paper is to investigate whether some sort of phonological processes, such as elision, aspiration, glottalisation, and hardening can be used to account for the behaviour of the glottal fricative (or approximant, as the case may be) ‘h’ in both French and Yoruba. French and Yoruba speakers generally tend to say, for instance ‘ockey’ and ‘amburger’, instead of ‘hockey’ and ‘hamburger’, respectively. Whereas the Yoruba conversely say, for instance ‘hadd’ for ‘add’, ‘heat’ for ‘eat’ on the one hand and ‘ard’ for ‘hard’, ‘eat’ for ‘heat’ on the other hand, on a similar note, it is not quite clear whether the French, however, if not at least in rare instances, would tend to force themselves to pronounce (in any form whatsoever) the h-sound.

Aspiration pneumonia is an aggressive type of pneumonia that results from inhalation of oropharyngeal secretions and/or gastric contents and is preventable. The authors hypothesized that an evidence-based aspiration pneumonia clinical care pathway could reduce 30-day hospital readmissions and mortality rates, while improving the overall care of patients. We conducted a retrospective chart review on 979 patients discharged with aspiration pneumonia from January 2021 to December 2022 at Overlook Medical Center. The authors identified patients who were coded with aspiration pneumonia and/or stable sepsis. Secondarily, we identified 30-day readmission rates for aspiration pneumonia from a SNF. The Aspiration Pneumonia Clinical Care Pathway starts in the emergency department (ED) with the initiation of antimicrobials within 4 hours of admission and early recognition of aspiration. Once this is identified, a swallow test is initiated by the bedside nurse, and if the patient demonstrates dysphagia, they are maintained on strict nothing by mouth (NPO) followed by a speech and language pathologist (SLP) referral for an appropriate modified diet recommendation. Aspiration prevention techniques included the avoidance of straws, 45-degree positioning, no talking during meals, taking small bites, placement of the aspiration wrist band, and consuming meals out of the bed in a chair. Nursing education was conducted with a newly created online learning module about aspiration pneumonia. The authors identified 979 patients, with an average age of 73.5 years old, who were diagnosed with aspiration pneumonia on the index hospitalization. These patients were reviewed for a 30-day readmission for aspiration pneumonia or stable sepsis, and mortality rates from January 2021 to December 2022 at Overlook Medical Center (OMC). The 30-day readmission rates were significantly lower in the cohort that received the clinical care pathway (35.0% vs. 27.5%, p = 0.011). When evaluating the mortality rates in the pre and post intervention cohort the authors discovered the mortality rates were lower in the post intervention cohort (23.7% vs 22.4%, p = 0.61) Mortality among non-white (self-reported as non-white) patients were lower in the post intervention cohort (34.4% vs. 21.0% , p = 0.05). Patients who reported as a current smoker/vaper in the pre and post cohorts had increased mortality rates (5.9% vs 22%). There was a decrease in mortality for the male population but an increase in mortality for women in the pre and post cohorts (19% vs. 25%). The authors attributed this increase in mortality in the post intervention cohort to more active smokers, more former smokers, and more being admitted from a SNF. This research identified that implementation of an Aspiration Pneumonia Clinical Care Pathway showed a statistically significant decrease in readmission rates and mortality rates in non-whites. The 30-day readmission rates were lower in the cohort that received the clinical care pathway (35.0% vs. 27.5%, p = 0.011). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aspiration%20pneumonia" title="aspiration pneumonia">aspiration pneumonia</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20improvement" title=" quality improvement"> quality improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=30-day%20pneumonia%20readmissions" title=" 30-day pneumonia readmissions"> 30-day pneumonia readmissions</a> </p> <a href="https://publications.waset.org/abstracts/176798/improving-patient-outcomes-for-aspiration-pneumonia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176798.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">62</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">252</span> Pneumoperitoneum Creation Assisted with Optical Coherence Tomography and Automatic Identification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eric%20Yi-Hsiu%20Huang">Eric Yi-Hsiu Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Meng-Chun%20Kao"> Meng-Chun Kao</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Chuan%20Kuo"> Wen-Chuan Kuo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For every laparoscopic surgery, a safe pneumoperitoneumcreation (gaining access to the peritoneal cavity) is the first and essential step. However, closed pneumoperitoneum is usually obtained by blind insertion of a Veress needle into the peritoneal cavity, which may carry potential risks suchas bowel and vascular injury.Until now, there remains no definite measure to visually confirm the position of the needle tip inside the peritoneal cavity. Therefore, this study established an image-guided Veress needle method by combining a fiber probe with optical coherence tomography (OCT). An algorithm was also proposed for determining the exact location of the needle tip through the acquisition of OCT images. Our method not only generates a series of “live” two-dimensional (2D) images during the needle puncture toward the peritoneal cavity but also can eliminate operator variation in image judgment, thus improving peritoneal access safety. This study was approved by the Ethics Committee of Taipei Veterans General Hospital (Taipei VGH IACUC 2020-144). A total of 2400 in vivo OCT images, independent of each other, were acquired from experiments of forty peritoneal punctures on two piglets. Characteristic OCT image patterns could be observed during the puncturing process. The ROC curve demonstrates the discrimination capability of these quantitative image features of the classifier, showing the accuracy of the classifier for determining the inside vs. outside of the peritoneal was 98% (AUC=0.98). In summary, the present study demonstrates the ability of the combination of our proposed automatic identification method and OCT imaging for automatically and objectively identifying the location of the needle tip. OCT images translate the blind closed technique of peritoneal access into a visualized procedure, thus improving peritoneal access safety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pneumoperitoneum" title="pneumoperitoneum">pneumoperitoneum</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20coherence%20tomography" title=" optical coherence tomography"> optical coherence tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20identification" title=" automatic identification"> automatic identification</a>, <a href="https://publications.waset.org/abstracts/search?q=veress%20needle" title=" veress needle"> veress needle</a> </p> <a href="https://publications.waset.org/abstracts/149622/pneumoperitoneum-creation-assisted-with-optical-coherence-tomography-and-automatic-identification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149622.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">134</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">251</span> Clinical Implication of Hyper-Intense Signal Thyroid Incidentaloma on Time of Flight Magnetic Resonance Angiography</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Inseon%20Ryoo">Inseon Ryoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Soo%20Chin%20Kim"> Soo Chin Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyena%20Jung"> Hyena Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangil%20Suh"> Sangil Suh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: The purpose of this study is to evaluate the clinical significance of hyper-intense signal thyroid incidentalomas on the time of flight magnetic resonance angiography (TOF-MRA) using correlation study with ultrasound (US). Methods: We retrospectively reviewed 3,505 non-contrast TOF-MRA performed at an institution between September 2014 and May 2017. Two radiologists correlated the thyroid incidentalomas detected on TOF-MRA with US features which was obtained within three months interval between MRA and US examinations in consensus method. Results: The prevalence of hyper-intense signal thyroid nodules incidentally detected on TOF-MRA was 1.2% (43/3505). Among them, 35 people (81.4%) underwent US examinations, and total 45 hyper-intense signal thyroid nodules were detected on US exams. Of these 45 nodules, 35 nodules (72.9%) were categorized as benign (K-TIRADS category 2) on US exams. Fine needle aspiration was performed on 9 nodules according to the indications recommended by Korean Society of Thyroid Radiology. All except one high-suspicious thyroid nodule were confirmed as benign (Bethesda 2) on cytologic exams. One high-suspicious nodule on US showed a non-diagnostic result (Bethesda 1) on cytologic exam. However, this nodule collapsed after aspiration of thick colloid material. Conclusions: Our study showed that the most hyper-intense signal thyroid nodules detected on TOF-MRA were benign. Therefore, if a hyper-intense signal incidentaloma is found on TOF-MRA, further evaluation, especially invasive biopsy of the nodules could be suspended unless the patient had other symptoms or clinical factors suggesting the need for further evaluation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=incidentaloma" title="incidentaloma">incidentaloma</a>, <a href="https://publications.waset.org/abstracts/search?q=thyroid%20nodule" title=" thyroid nodule"> thyroid nodule</a>, <a href="https://publications.waset.org/abstracts/search?q=TOF%20MR%20angiography" title=" TOF MR angiography"> TOF MR angiography</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a> </p> <a href="https://publications.waset.org/abstracts/93144/clinical-implication-of-hyper-intense-signal-thyroid-incidentaloma-on-time-of-flight-magnetic-resonance-angiography" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93144.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">250</span> Brown-Spot Needle Blight: An Emerging Threat Causing Loblolly Pine Needle Defoliation in Alabama, USA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debit%20Datta">Debit Datta</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20J.%20Coleman"> Jeffrey J.

Eckhardt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Loblolly pine (Pinus taeda) is a leading productive timber species in the southeastern USA. Over the past three years, an emerging threat is expressed by successive needle defoliation followed by stunted growth and tree mortality in loblolly pine plantations. Considering economic significance, it has now become a rising concern among landowners, forest managers, and forest health state cooperators. However, the symptoms of the disease were perplexed somewhat with root disease(s) and recurrently attributed to invasive Phytophthora species due to the similarity of disease nature and devastation. Therefore, the study investigated the potential causal agent of this disease and characterized the fungi associated with loblolly pine needle defoliation in the southeastern USA. Besides, 70 trees were selected at seven long-term monitoring plots at Chatom, Alabama, to monitor and record the annual disease incidence and severity. Based on colony morphology and ITS-rDNA sequence data, a total of 28 species of fungi representing 17 families have been recovered from diseased loblolly pine needles. The native brown-spot pathogen, Lecanosticta acicola, was the species most frequently recovered from unhealthy loblolly pine needles in combination with some other common needle cast and rust pathogen(s). Identification was confirmed using morphological similarity and amplification of translation elongation factor 1-alpha gene region of interest. Tagged trees were consistently found chlorotic and defoliated from 2019 to 2020. The current emergence of the brown-spot pathogen causing loblolly pine mortality necessitates the investigation of the role of changing climatic conditions, which might be associated with increased pathogen pressure to loblolly pines in the southeastern USA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brown-spot%20needle%20blight" title="brown-spot needle blight">brown-spot needle blight</a>, <a href="https://publications.waset.org/abstracts/search?q=loblolly%20pine" title=" loblolly pine"> loblolly pine</a>, <a href="https://publications.waset.org/abstracts/search?q=needle%20defoliation" title=" needle defoliation"> needle defoliation</a>, <a href="https://publications.waset.org/abstracts/search?q=plantation%20forestry" title=" plantation forestry"> plantation forestry</a> </p> <a href="https://publications.waset.org/abstracts/134448/brown-spot-needle-blight-an-emerging-threat-causing-loblolly-pine-needle-defoliation-in-alabama-usa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134448.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">249</span> Patterns of Malignant and Benign Breast Lesions in Hail Region: A Retrospective Study at King Khalid Hospital</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laila%20Seada">Laila Seada</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Ibrahim"> Ashraf Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Amjad%20Al%20Shammari"> Amjad Al Shammari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Objectives: Breast carcinoma is the most common cancer of females in Hail region, accounting for 31% of all diagnosed cancer cases followed by thyroid carcinoma (25%) and colorectal carcinoma (13%). Methods: In the present retrospective study, all cases of breast lesions received at the histopathology department in King Khalid Hospital, Hail, during the period from May 2011 to April 2016 have been retrieved from department files. For all cases, a trucut biopsy, lumpectomy, or modified radical mastectomy was available for histopathologic diagnosis, while 105/140 (75%) had, as well, preoperative fine needle aspirates (FNA). Results: 49 cases out of 140 (35%) breast lesions were carcinomas: 44/49 (89.75%) was invasive ductal, 2/49(4.1%) invasive lobular carcinomas, 1/49(2.05%) intracystic low grade papillary carcinoma and 2/49 (4.1%) ductal carcinoma in situ (DCIS). Mean age for malignant cases was 45.06 (+/-10.58): 32.6% were below the age of 40 and 30.6 below 50 years, 18.3% below 60 and 16.3% below 70 years. For the benign group, mean age was 32.52 (+/10.5) years. Benign lesions were in order of frequency: 34 fibroadenomas, 14 fibrocystic disease, 12 chronic mastitis, five granulomatous mastitis, three intraductal papillomas, and three benign phyllodes tumor. Tubular adenoma, lipoma, skin nevus, pilomatrixoma, and breast reduction specimens constituted the remaining specimens. Conclusion: Breast lesions are common in our series and invasive carcinoma accounts for more than 1/3<sup>rd</sup> of the lumps, with 63.2% incidence in pre-menopausal ladies, below the age of 50 years. FNA as a non-invasive procedure, proved to be an effective tool in diagnosing both benign and malignant/suspicious breast lumps and should continue to be used as a first assessment line of palpable breast masses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=age%20incidence" title="age incidence">age incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20carcinoma" title=" breast carcinoma"> breast carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=fine%20needle%20aspiration" title=" fine needle aspiration"> fine needle aspiration</a>, <a href="https://publications.waset.org/abstracts/search?q=hail%20region" title=" hail region"> hail region</a> </p> <a href="https://publications.waset.org/abstracts/72605/patterns-of-malignant-and-benign-breast-lesions-in-hail-region-a-retrospective-study-at-king-khalid-hospital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72605.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">279</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">248</span> Effect of Needle Height on Discharge Coefficient and Cavitation Number</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Nezamirad">Mohammadreza Nezamirad</a>, <a href="https://publications.waset.org/abstracts/search?q=Sepideh%20Amirahmadian"> Sepideh Amirahmadian</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasim%20Sabetpour"> Nasim Sabetpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Azadeh%20Yazdi"> Azadeh Yazdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amirmasoud%20Hamedi"> Amirmasoud Hamedi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cavitation inside diesel injector nozzle is investigated using Reynolds-Stress-Navier Stokes equations. Schnerr-Sauer cavitation model is used for modeling cavitation inside diesel injector nozzle. The carrying fluid utilized in the current study is diesel fuel. The flow is verified at the beginning by comparing with the previous experimental data, and it was found that K-Epsilon turbulent model could lead to a better accuracy comparing to K-Omega turbulent model. Moreover, the mass flow rate obtained numerically is compared with the experimental value, and the discrepancy was found to be less than 5 percent which shows the accuracy of the current results. Finally, a real-size four-hole nozzle is investigated, and the flow inside it is visualized based on velocity profile, discharge coefficient, and cavitation number. It was found that the mesh density could be reduced significantly by utilizing periodic boundary conditions. Velocity contour at the mid nozzle showed that the maximum value of velocity occurs at the end of the needle before entering the orifice area. Last but not least, at the same boundary conditions, when different needle heights were utilized, it was found that as needle height increases with an increase in cavitation number, discharge coefficient increases, while the mentioned increases are more tangible at smaller values of needle heights. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cavitation" title="cavitation">cavitation</a>, <a href="https://publications.waset.org/abstracts/search?q=diesel%20fuel" title=" diesel fuel"> diesel fuel</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20size%20nozzle" title=" real size nozzle"> real size nozzle</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20flow%20rate" title=" mass flow rate"> mass flow rate</a> </p> <a href="https://publications.waset.org/abstracts/138113/effect-of-needle-height-on-discharge-coefficient-and-cavitation-number" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138113.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">247</span> Comparative Evaluation of Ultrasound Guided Internal Jugular Vein Cannulation Using Measured Guided Needle and Conventional Size Needle for Success and Complication of Cannulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Devendra%20Gupta">Devendra Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikash%20Arya"> Vikash Arya</a>, <a href="https://publications.waset.org/abstracts/search?q=Prabhat%20K.%20Singh"> Prabhat K.

Central venous cannulation set has a single puncture needle of a fixed length of 6.4 cm. However, the average distance of midpoint of IJV to the skin is around 1 cm to 2 cm. The long length needle has tendency to go in depth more than required and this is very common during learning period of any individual. Therefore, we devised a long needle with a guard which can be adjusted according to the required length. Methods: After approval from the institute ethics committee and patient’s written informed consent, a prospective, randomized, single-blinded controlled study was conducted. Adult patient aged of both sexes with ASA grade 1-2 undergoing surgery requiring internal jugular venous (IJV) access was included. After intubation, the head was rotated to the contralateral side at 30 degree head rotation on the position of the right IJV. The transducer probe a 6.5 to 13-MHz linear transducer (Sonosite, USA) had been placed at the apex of triangle with minimal pressure to avoid IJV compression. The distance from skin to midpoint of the right IJV and skin to anterior wall of Common Carotid Artery (CCA) had been done using B-mode duplex sonography with a 6.5 to 13-MHz linear transducer. Depending upon the results of randomization 420 patients had been divided into two groups of equal numbers (n=210). Group 1. USG guided right sided IJV cannulation was done with conventional (6.4 cm) needle; and Group 2. USG guided right sided IJV cannulation was done with conventional (6.4 cm) needle with guard fixed to a required length (length between skin and midpoint of IJV) by an experienced anesthesiologist. Independent observer has noted the number of attempts and occurrence of complications (CCA puncture, pneumothorax or adjacent tissue damage). Results: Demographic data were similar in both the group. The groups were comparable when considered for relationship of IJV to CCA. There was no significant difference between groups as regard to distance of midpoint of IJV to the skin (p<0.05). IJV cannulation was successfully done in single attempts in 180 (85.7%), in two attempts in 27 (12.9%) and three attempts in 3 (1.4%) in group I, whereas in single attempt in 207 (98.6%) and second attempts in 3 (1.4%) in group II (p <0.000). Incidence of carotid artery puncture was significantly more in group I (7.1%) compared to group II (0%) (p<0.000). Incidence of adjacent tissue puncture was significantly more in group I (8.6%) compared to group II (0%) (p<0.000). Conclusion: Therefore IJV catheterization using guard over the needle at predefined length with the help of real-time ultrasound results in better success rates and lower immediate complications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultrasound%20guided" title="ultrasound guided">ultrasound guided</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20jugular%20vein%20cannulation" title=" internal jugular vein cannulation"> internal jugular vein cannulation</a>, <a href="https://publications.waset.org/abstracts/search?q=measured%20guided%20needle" title=" measured guided needle"> measured guided needle</a>, <a href="https://publications.waset.org/abstracts/search?q=common%20carotid%20artery%20puncture" title=" common carotid artery puncture"> common carotid artery puncture</a> </p> <a href="https://publications.waset.org/abstracts/55515/comparative-evaluation-of-ultrasound-guided-internal-jugular-vein-cannulation-using-measured-guided-needle-and-conventional-size-needle-for-success-and-complication-of-cannulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55515.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">246</span> Correlates of Multiplicity of Risk Behavior among Injecting Drug Users in Three High HIV Prevalence States of India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santosh%20Sharma">Santosh Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Drug abuse, needle sharing, and risky sexual behaviour are often compounded to increase the risk of HIV transmission. Injecting Drug Users are at the duel risk of needle sharing and risky sexual Behaviour, becoming more vulnerable to STI and HIV. Thus, studying the interface of injecting drug use and risky sexual behaviour is important to curb the pace of HIV epidemic among IDUs. The aim of this study is to determine the factor associated with HIV among injecting drug users in three states of India. Materials and methods: This paper analyzes covariates of multiplicity of risk behavior among injecting drug users. Findings are based on data from Integrated Behavioral and Biological Assessment (IBBA) round 2, 2010. IBBA collects the information of IDUs from the six districts. IDUs were selected on the criteria of those who were 18 years or older, who injected addictive substances/drugs for non-medical purposes at least once in past six month. A total of 1,979 in round 2 were interviewed in the IBBA. The study employs quantitative techniques using standard statistical tools to achieve the above objectives. All results presented in this paper are unweighted univariate measures. Results: Among IDUs, average duration of injecting drugs is 5.2 years. Mean duration between first drug use to first injecting drugs among younger IDUs, belongs to 18-24 years is 2.6 years Needle cleaning practices is common with above two-fifths reporting its every time cleaning. Needle sharing is quite prevalent especially among younger IDUs. Further, IDUs practicing needle sharing exhibit pervasive multi-partner behavior. Condom use with commercial partners is almost 81 %, whereas with intimate partner it is 39 %. Coexistence of needle sharing and unprotected sex enhances STI prevalence (6.8 %), which is further pronounced among divorced/separated/widowed (9.4 %). Conclusion: Working towards risk reduction for IDUs must deal with multiplicity of risk. Interventions should deal with covariates of risk, addressing youth, and risky sexual behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IDUs" title="IDUs">IDUs</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV" title=" HIV"> HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=STI" title=" STI"> STI</a>, <a href="https://publications.waset.org/abstracts/search?q=behaviour" title=" behaviour"> behaviour</a> </p> <a href="https://publications.waset.org/abstracts/59002/correlates-of-multiplicity-of-risk-behavior-among-injecting-drug-users-in-three-high-hiv-prevalence-states-of-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59002.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">279</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">245</span> Efficacy of In-Situ Surgical vs. Needle Revision on Late Failed Trabeculectomy Blebs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xie%20Xiaobin">Xie Xiaobin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Yan"> Zhang Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shi%20Yipeng"> Shi Yipeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun%20Wenying"> Sun Wenying</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen%20Shuang"> Chen Shuang</a>, <a href="https://publications.waset.org/abstracts/search?q=Cai%20Zhipeng"> Cai Zhipeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Hong"> Zhang Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Lixia"> Zhang Lixia</a>, <a href="https://publications.waset.org/abstracts/search?q=Xie%20Like"> Xie Like</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: The objective of this research is to compare the efficacy of the late in-situ surgical revision augmented with continuous infusion and needle revision on failed trabeculectomy blebs. Methods From December 2018 to December 2021, a prospective randomized controlled trial was performed on 44 glaucoma patients with failed bleb ≥ 6months with medically uncontrolled in Eye Hospital, China Academy of Chinese Medical Sciences. They were randomly divided into two groups. 22 eyes of 22 patients underwent the late in-situ surgical revision with continuous anterior chamber infusion in the study group, and 22 of 22 patients were treated with needle revision in the control group. Main outcome measures include preoperative and postoperative intraocular pressure (IOP), the number of anti-glaucoma medicines, the operation success rate, and the postoperative complications. Results The postoperative IOP values decreased significantly from the baseline in both groups (both P<0.05). IOP was significantly lower in the study group than in the control group at one week, 1, and 3 months postoperatively (all P<0.05). IOP reductions in the study group were substantially more prominent than in the control group at all postoperative time points (all P<0.05). The complete success rate in the study group was significantly higher than in the control group (71.4% vs. 33.3%, P<0.05), while the complete failure rate was significantly lower in the study group (0% vs. 28.5%, P<0.05). According to Cox’s proportional hazards regression analysis, high IOP at baseline was independently associated with increased risks of complete failure (adjusted hazard ratio=1.141, 95% confidence interval=1.021-1.276, P<0.05). There was no significant difference in the incidence of postoperative complications between the two groups (P>0.05). Conclusion: Both in-situ surgical and needle revision have acceptable success rates and safety for the late failed trabeculectomy blebs, while the former is likely to have a higher level of efficacy over the latter. Needle revision may be insufficient for eyes with low target IOP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glaucoma" title="glaucoma">glaucoma</a>, <a href="https://publications.waset.org/abstracts/search?q=trabeculectomy%20blebs" title=" trabeculectomy blebs"> trabeculectomy blebs</a>, <a href="https://publications.waset.org/abstracts/search?q=in-situ%20surgical%20revision" title=" in-situ surgical revision"> in-situ surgical revision</a>, <a href="https://publications.waset.org/abstracts/search?q=needle%20revision" title=" needle revision"> needle revision</a> </p> <a href="https://publications.waset.org/abstracts/151168/efficacy-of-in-situ-surgical-vs-needle-revision-on-late-failed-trabeculectomy-blebs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151168.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">244</span> Appropriate Depth of Needle Insertion during Rhomboid Major Trigger Point Block</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seongho%20Jang">Seongho Jang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To investigate an appropriate depth of needle insertion during trigger point injection into the rhomboid major muscle. Methods: Sixty-two patients who visited our department with shoulder or upper back pain participated in this study. The distance between the skin and the rhomboid major muscle (SM) and the distance between the skin and rib (SB) were measured using ultrasonography. The subjects were divided into 3 groups according to BMI: BMI less than 23 kg/m2 (underweight or normal group); 23 kg/m2 or more to less than 25 kg/m2 (overweight group); and 25 kg/m2 or more (obese group). The mean ±standard deviation (SD) of SM and SB of each group were calculated. A range between mean+1 SD of SM and the mean-1 SD of SB was defined as a safe margin. Results: The underweight or normal group’s SM, SB, and the safe margin were 1.2±0.2, 2.1±0.4, and 1.4 to 1.7 cm, respectively. The overweight group’s SM and SB were 1.4±0.2 and 2.4±0.9 cm, respectively. The safe margin could not be calculated for this group. The obese group’s SM, SB, and the safe margin were 1.8±0.3, 2.7±0.5, and 2.1 to 2.2 cm, respectively. Conclusion: This study will help us to set the standard depth of safe needle insertion into the rhomboid major muscle in an effective manner without causing any complications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pneumothorax" title="pneumothorax">pneumothorax</a>, <a href="https://publications.waset.org/abstracts/search?q=rhomboid%20major%20muscle" title=" rhomboid major muscle"> rhomboid major muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=trigger%20point%20injection" title=" trigger point injection"> trigger point injection</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound "> ultrasound </a> </p> <a href="https://publications.waset.org/abstracts/37418/appropriate-depth-of-needle-insertion-during-rhomboid-major-trigger-point-block" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37418.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">243</span> Effect of Sewing Speed on the Physical Properties of Firefighter Sewing Threads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Mazari">Adnan Mazari</a>, <a href="https://publications.waset.org/abstracts/search?q=Engin%20Akcagun"> Engin Akcagun</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonin%20Havelka"> Antonin Havelka</a>, <a href="https://publications.waset.org/abstracts/search?q=Funda%20Buyuk%20Mazari"> Funda Buyuk Mazari</a>, <a href="https://publications.waset.org/abstracts/search?q=Pavel%20Kejzlar"> Pavel Kejzlar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article experimentally investigates various physical properties of special fire retardant sewing threads under different sewing speeds. The aramid threads are common for sewing the fire-fighter clothing due to high strength and high melting temperature. 3 types of aramid threads with different linear densities are used for sewing at different speed of 2000 to 4000 r/min. The needle temperature is measured at different speeds of sewing and tensile properties of threads are measured before and after the sewing process respectively. The results shows that the friction and abrasion during the sewing process causes a significant loss to the tensile properties of the threads and needle temperature rises to nearly 300<sup>o</sup>C at 4000 r/min of machine speed. The Scanning electron microscope images are taken before and after the sewing process and shows no melting spots but significant damage to the yarn. It is also found that machine speed of 2000r/min is ideal for sewing firefighter clothing for higher tensile properties and production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kevlar" title="Kevlar">Kevlar</a>, <a href="https://publications.waset.org/abstracts/search?q=needle%20temperautre" title=" needle temperautre"> needle temperautre</a>, <a href="https://publications.waset.org/abstracts/search?q=nomex" title=" nomex"> nomex</a>, <a href="https://publications.waset.org/abstracts/search?q=sewing" title=" sewing"> sewing</a> </p> <a href="https://publications.waset.org/abstracts/43164/effect-of-sewing-speed-on-the-physical-properties-of-firefighter-sewing-threads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43164.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">532</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">242</span> A Computational Analysis of Gas Jet Flow Effects on Liquid Aspiration in the Collison Nebulizer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=James%20Q.%20Feng">James Q. Feng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pneumatic nebulizers (as variations based on the Collison nebulizer) have been widely used for producing fine aerosol droplets from a liquid material. As qualitatively described by many authors, the basic working principle of those nebulizers involves utilization of the negative pressure associated with an expanding gas jet to syphon liquid into the jet stream, then to blow and shear into liquid sheets, filaments, and eventually droplets. But detailed quantitative analysis based on fluid mechanics theory has been lacking in the literature. The purpose of present work is to investigate the nature of negative pressure distribution associated with compressible gas jet flow in the Collison nebulizer by a computational fluid dynamics (CFD) analysis, using an OpenFOAM® compressible flow solver. The value of the negative pressure associated with a gas jet flow is examined by varying geometric parameters of the jet expansion channel adjacent to the jet orifice outlet. Such an analysis can provide valuable insights into fundamental mechanisms in liquid aspiration process, helpful for effective design of the pneumatic atomizer in the Aerosol Jet® direct-write system for micro-feature, high-aspect-ratio material deposition in additive manufacturing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collison%20nebulizer" title="collison nebulizer">collison nebulizer</a>, <a href="https://publications.waset.org/abstracts/search?q=compressible%20gas%20jet%20flow" title=" compressible gas jet flow"> compressible gas jet flow</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20aspiration" title=" liquid aspiration"> liquid aspiration</a>, <a href="https://publications.waset.org/abstracts/search?q=pneumatic%20atomization" title=" pneumatic atomization"> pneumatic atomization</a> </p> <a href="https://publications.waset.org/abstracts/86534/a-computational-analysis-of-gas-jet-flow-effects-on-liquid-aspiration-in-the-collison-nebulizer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86534.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">179</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">241</span> Abdominal Exercises Can Modify Abdominal Function in Postpartum Women: A Randomized Control Trial Comparing Curl-up to Drawing-in Combined With Diaphragmatic Aspiration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yollande%20S%C3%A8nan%20Djivoh">Yollande Sènan Djivoh</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominique%20de%20Jaeger"> Dominique de Jaeger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Abdominal exercises are commonly practised nowadays. Specific techniques of abdominal muscles strengthening like hypopressive exercises have recently emerged and their practice is encouraged against the practice of Curl-up especially in postpartum. The acute and the training effects of these exercises did not allow to advise one exercise to the detriment of another. However, physiotherapists remain reluctant to perform Curl-up with postpartum women because of its potential harmful effect on the pelvic floor. Design: This study was a randomized control trial registered under the number PACTR202110679363984. Objective: to observe the training effect of two experimental protocols (Curl-up versus Drawing-in+Diaphragmatic aspiration) on the abdominal wall (interrecti distance, rectus and transversus abdominis thickness, abdominal strength) in Beninese postpartum women. Pelvic floor function (tone, endurance, urinary incontinence) will be assessed to evaluate potential side effects of exercises on the pelvic floor. Method: Postpartum women diagnosed with diastasis recti were randomly assigned to one of three groups (Curl-up, Drawingin+Diaphragmatic aspiration and control). Abdominal and pelvic floor parameters were assessed before and at the end of the 6-week protocol. The interrecti distance and the abdominal muscles thickness were assessed by ultrasound and abdominal strength by dynamometer. Pelvic floor tone and strength were assessed with Biofeedback and urinary incontinence was quantified by pad test. To compare the results between the three groups and the two measurements, a two-way Anova test with repeated measures was used (p<0.05). When interaction was significant, a posthoc using Student t test, with Bonferroni correction, was used to compare the three groups regarding the difference (end value minus initial value). To complete these results, a paired Student t test was used to compare in each group the initial and end values. Results: Fifty-eight women participated in this study, divided in three groups with similar characteristics regarding their age (29±5 years), parity (2±1 children), BMI (26±4 kg/m2 ), time since the last birth (10±2 weeks), weight of their baby at birth (330±50 grams). Time effect and interaction were significant (p<0.001) for all abdominal parameters. Experimental groups improved more than control group. Curl-up group improved more (p=0.001) than Drawing-in+Diaphragmatic aspiration group regarding the interrecti distance (9.3±4.2 mm versus 6.6±4.6 mm) and abdominal strength (20.4±16.4 Newton versus 11.4±12.8 Newton). Drawingin+Diaphragmatic aspiration group improved (0.8±0.7 mm) more than Curl-up group (0.5±0.7 mm) regarding the transversus abdominis thickness (p=0.001). Only Curl-up group improved (p<0.001) the rectus abdominis thickness (1.5±1.2 mm). For pelvic floor parameters, both experimental groups improved (p=0.01) except for tone which improved (p=0.03) only in Drawing-in+Diaphragmatic aspiration group from 19.9±4.1 cmH2O to 22.2±4.5 cmH2O. Conclusion: Curl-up was more efficient to improve abdominal function than Drawingin+Diaphragmatic aspiration. However, these exercises are complementary. None of them degraded the pelvic floor, but Drawing-in+Diaphragmatic aspiration improved further the pelvic floor function. Clinical implications: Curl-up, Drawing-in and Diaphragmatic aspiration can be used for the management of abdominal function in postpartum women. Exercises must be chosen considering the specific needs of each woman’s abdominal and pelvic floor function. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curl-up" title="curl-up">curl-up</a>, <a href="https://publications.waset.org/abstracts/search?q=drawing-in" title=" drawing-in"> drawing-in</a>, <a href="https://publications.waset.org/abstracts/search?q=diaphragmatic%20aspiration" title=" diaphragmatic aspiration"> diaphragmatic aspiration</a>, <a href="https://publications.waset.org/abstracts/search?q=hypopressive%20exercise" title=" hypopressive exercise"> hypopressive exercise</a>, <a href="https://publications.waset.org/abstracts/search?q=postpartum%20women" title=" postpartum women"> postpartum women</a> </p> <a href="https://publications.waset.org/abstracts/160083/abdominal-exercises-can-modify-abdominal-function-in-postpartum-women-a-randomized-control-trial-comparing-curl-up-to-drawing-in-combined-with-diaphragmatic-aspiration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160083.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">240</span> Experimental Investigation of Compressed Natural Gas Injector for Direct Injection System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafal%20Sochaczewski">Rafal Sochaczewski</a>, <a href="https://publications.waset.org/abstracts/search?q=Grzegorz%20Baranski"> Grzegorz Baranski</a>, <a href="https://publications.waset.org/abstracts/search?q=Adam%20Majczak"> Adam Majczak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the bench research results on a CNG injector at steady state. The quantities measured included voltage and current in a solenoid, pressure of gas behind an injector and injector’s flow rate. Accordingly, injector’s operation parameters were determined according to needle’s lift and injection pressure. The discrepancies between the theoretical (electric) and actual time of injection were defined to specify injector’s opening and closing lag times and the uniqueness of these values in successive cycles of gas injection. It has been demonstrated that needle’s lift has got a stronger impact on injector’s operating parameters than injection pressure. With increasing injection pressure, the force increases and closes an injection valve, which adversely affects uniqueness of injector’s operation. The paper also describes the concept of an injector dedicated to direct CNG injection into a combustion chamber in a dual-fuel engine. The injector’s design enables us to replace 80% of diesel fuel in a dual-fuel engine with a maximum power of 85 kW. Minimum injection pressure is 1,4 MPa then.
