The purpose of this research had been to investigate the problem of anti-phase synchronization for complex delayed dynamical networks with output coupling. The coupling configuration is general, with the coupling matrix not assumed to be symmetric or irreducible. The amount of the coupling variables between two connected nodes is flexible, the nodes in the drive and response systems need not to be identical and there is not any extra constraint on the coupling matrix. Some pinning controllers are designed to make the drive-response system achieve the anti-phase synchronization. For the convenience of description, we applied the matrix Kronecker product. Some new criteria are proposed based on the Lyapunov stability theory, linear matrix inequalities (LMI) and Schur complement. Lastly, some simulation examples are provided to illustrate the effectiveness of our proposed conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-phase%20synchronization" title="anti-phase synchronization">anti-phase synchronization</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20networks" title=" complex networks"> complex networks</a>, <a href="https://publications.waset.org/abstracts/search?q=output%20coupling" title=" output coupling"> output coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=pinning%20control" title=" pinning control"> pinning control</a> </p> <a href="https://publications.waset.org/abstracts/38055/anti-phase-synchronization-of-complex-delayed-networks-with-output-coupling-via-pinning-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38055.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">394</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">79</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">78</span> Comparative Outcomes of Percutaneous Coronary Intervention in Smokers versus Non Nonsmokers Patients: Observational Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pratima%20Tatke">Pratima Tatke</a>, <a href="https://publications.waset.org/abstracts/search?q=Archana%20Avhad"> Archana Avhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Bhanu%20Duggal"> Bhanu Duggal</a>, <a href="https://publications.waset.org/abstracts/search?q=Meeta%20Rajivlochan"> Meeta Rajivlochan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sujata%20Saunik"> Sujata Saunik</a>, <a href="https://publications.waset.org/abstracts/search?q=Pradip%20Vyas"> Pradip Vyas</a>, <a href="https://publications.waset.org/abstracts/search?q=Nidhi%20Pandey"> Nidhi Pandey</a>, <a href="https://publications.waset.org/abstracts/search?q=Aditee%20Dalvi"> Aditee Dalvi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jyothi%20Subramanian"> Jyothi Subramanian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Smoking is well established risk factor for the development and progression of coronary artery disease. It is strongly related to morbidity and mortality from cardiovascular causes. The aim of this study is to observe effect of smoking status on percutaneous coronary intervention(PCI) after 1 year. Methods: 2527 patients who underwent PCI at different hospital of Maharashtra(India) from 2012 to 2015 under the health insurance scheme which is launched by Health department, Government of Maharashtra for below poverty line(BPL) families which covers cardiology. Informed consent of patients was taken .They were followed by telephonic survey after 6months to 1year of PCI . Outcomes of interest included myocardial infarction, restenosis, cardiac rehospitalization, death, and a composite of events after PCI. Made group of two non smokers-1861 and smokers (including patients who quit at time of PCI )-659. Results: Statistical Analysis using Pearson’s chi square test revealed that there was trend seen of increasing incidence of death, Myocardial infarction and Restenosis in smokers than non smokers .Smokers had a greater death risk compared to nonsmoker; 5.7% and 5.1% respectively p=0.518. Also Repeat procedures (2.1% vs. 1.5% p=0.222), breathlessness (17.8% vs. 18.20% p=0.1) and Myocardial Infarction (7.3% vs. 10%) high in smoker than non smokers. Conclusion: Major adverse cardiovascular events (MACE) were observed even after successful PCI in smokers. Patients undergoing percutaneous coronary intervention should be encouraged to stop smoking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coronary%20artery%20diseases" title="coronary artery diseases">coronary artery diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=major%20adverse%20cardiovascular%20events" title=" major adverse cardiovascular events"> major adverse cardiovascular events</a>, <a href="https://publications.waset.org/abstracts/search?q=percutaneous%20coronary%20intervention" title=" percutaneous coronary intervention"> percutaneous coronary intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=smoking" title=" smoking"> smoking</a> </p> <a href="https://publications.waset.org/abstracts/80586/comparative-outcomes-of-percutaneous-coronary-intervention-in-smokers-versus-non-nonsmokers-patients-observational-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80586.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">210</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">77</span> YBa2Cu3O7-d Nanoparticles Doped by Ferromagnetic Nanoparticles of Y3Fe5O12</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samir%20Khene">Samir Khene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Present and future industrial uses of high critical temperature superconductors require high critical temperatures TC and strong current densities JC.

Koblischka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To increase the flux pinning performance of bulk YBa2Cu3O7-δ (YBCO or Y-123) superconductors, it is common to employ secondary phase particles, either Y2BaCuO5 (Y-211) particles created during the growth of the samples or additionally added (nano)particles of various types, embedded in the superconducting Y-123 matrix. As the crystallographic parameters of all the particles indicate a misfit to Y-123, there will be residual strain within the Y-123 matrix around such particles. With a dedicated analysis of electron backscatter diffraction (EBSD) data obtained on various bulk, Y-123 superconductor samples, the strain distribution around such embedded secondary phase particles can be revealed. The results obtained are presented in form of Kernel Average Misorientation (KAM) mappings. Around large Y-211 particles, the strain can be so large that YBCO subgrains are formed. Therefore, it is essential to properly control the particle size as well as their distribution within the bulk sample to obtain the best performance. The impact of the strain distribution on the flux pinning properties is discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bulk%20superconductors" title="Bulk superconductors">Bulk superconductors</a>, <a href="https://publications.waset.org/abstracts/search?q=EBSD" title=" EBSD"> EBSD</a>, <a href="https://publications.waset.org/abstracts/search?q=Strain" title=" Strain"> Strain</a>, <a href="https://publications.waset.org/abstracts/search?q=YBa2Cu3Oy" title=" YBa2Cu3Oy"> YBa2Cu3Oy</a> </p> <a href="https://publications.waset.org/abstracts/122638/residual-stress-around-embedded-particles-in-bulk-yba2cu3oy-samples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122638.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">150</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">75</span> A Prospective Study of a Modified Pin-In-Plaster Technique for Treatment of Distal Radius Fractures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20alireza%20Mirghasemi">S. alireza Mirghasemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shervin%20Rashidinia"> Shervin Rashidinia</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadsaleh%20Sadeghi"> Mohammadsaleh Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Talebizadeh"> Mohsen Talebizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Narges%20Rahimi%20Gabaran"> Narges Rahimi Gabaran</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Shahin%20Eftekhari"> S.

This study is meant to introduce a modified technique of pin-in-plaster. Materials and methods: Fifty-four patients with distal radius fractures were followed up for one year. Patients were excluded if they had type B fractures according to AO classification, multiple injuries or pathological fractures, and were treated more than 7 days after injury. Range of motion and functional results were evaluated. Radiographic parameters including radial inclination, tilt, and height, were measured preoperatively and postoperatively. Results: The average radial tilt was 10.6° and radial height was 10.2 mm at the sixth month postoperatively. Three cases of pin tract infection were recorded, who were treated totally with oral antibiotics. There was no case of pin loosening. Of total 73 patients underwent surgery, three cases of radial nerve irritation were recorded at the time of cast removal. All of them resolved at the 6th month follow up. No median nerve compression and carpal tunnel syndrome have found. We also had no case of tendon injury. Conclusion: Our modified technique is effective to restore anatomic congruity and maintain reduction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distal%20radius%20fracture" title="distal radius fracture">distal radius fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=percutaneous%20pinning" title=" percutaneous pinning"> percutaneous pinning</a>, <a href="https://publications.waset.org/abstracts/search?q=pin-in-plaster" title=" pin-in-plaster"> pin-in-plaster</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20method%20of%20pin-in-plaster" title=" modified method of pin-in-plaster"> modified method of pin-in-plaster</a>, <a href="https://publications.waset.org/abstracts/search?q=operative%20treatment" title=" operative treatment"> operative treatment</a> </p> <a href="https://publications.waset.org/abstracts/34784/a-prospective-study-of-a-modified-pin-in-plaster-technique-for-treatment-of-distal-radius-fractures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34784.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">509</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">74</span> A Review of Pharmacological Prevention of Peri-and Post-Procedural Myocardial Injury After Percutaneous Coronary Intervention</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Dawood%20Md.%20Taimur">Syed Dawood Md.

The final consequence of this event is left ventricular (LV) systolic dysfunction leading to increased morbidity and mortality. The typical clinical case of reperfusion injury occurs in acute myocardial infarction (MI) with ST segment elevation in which an occlusion of a major epicardial coronary artery is followed by recanalization of the artery. This may occur either spontaneously or by means of thrombolysis and/or by primary percutaneous coronary intervention (PCI) with efficient platelet inhibition by aspirin (acetylsalicylic acid), clopidogrel and glycoprotein IIb/IIIa inhibitors. In recent years, percutaneous coronary intervention (PCI) has become a well-established technique for the treatment of coronary artery disease. PCI improves symptoms in patients with coronary artery disease and it has been increasing the safety of procedures. However, peri- and post-procedural myocardial injury, including angiographical slow coronary flow, microvascular embolization, and elevated levels of cardiac enzyme, such as creatine kinase and troponin-T and -I, has also been reported even in elective cases. Furthermore, myocardial reperfusion injury at the beginning of myocardial reperfusion, which causes tissue damage and cardiac dysfunction, may occur in cases of the acute coronary syndrome. Because patients with myocardial injury is related to larger myocardial infarction and have a worse long-term prognosis than those without myocardial injury, it is important to prevent myocardial injury during and/or after PCI in patients with coronary artery disease. To date, many studies have demonstrated that adjunctive pharmacological treatment suppresses myocardial injury and increases coronary blood flow during PCI procedures. In this review, we highlight the usefulness of pharmacological treatment in combination with PCI in attenuating myocardial injury in patients with coronary artery disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coronary%20artery%20disease" title="coronary artery disease">coronary artery disease</a>, <a href="https://publications.waset.org/abstracts/search?q=percutaneous%20coronary%20intervention" title=" percutaneous coronary intervention"> percutaneous coronary intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=myocardial%20injury" title=" myocardial injury"> myocardial injury</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmacology" title=" pharmacology "> pharmacology </a> </p> <a href="https://publications.waset.org/abstracts/2256/a-review-of-pharmacological-prevention-of-peri-and-post-procedural-myocardial-injury-after-percutaneous-coronary-intervention" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2256.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">451</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">73</span> Inertial Spreading of Drop on Porous Surfaces </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shilpa%20Sahoo">Shilpa Sahoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Louge"> Michel Louge</a>, <a href="https://publications.waset.org/abstracts/search?q=Anthony%20Reeves"> Anthony Reeves</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Desjardins"> Olivier Desjardins</a>, <a href="https://publications.waset.org/abstracts/search?q=Susan%20Daniel"> Susan Daniel</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadik%20Omowunmi"> Sadik Omowunmi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The microgravity on the International Space Station (ISS) was exploited to study the imbibition of water into a network of hydrophilic cylindrical capillaries on time and length scales long enough to observe details hitherto inaccessible under Earth gravity. When a drop touches a porous medium, it spreads as if laid on a composite surface. The surface first behaves as a hydrophobic material, as liquid must penetrate pores filled with air. When contact is established, some of the liquid is drawn into pores by a capillarity that is resisted by viscous forces growing with length of the imbibed region. This process always begins with an inertial regime that is complicated by possible contact pinning. To study imbibition on Earth, time and distance must be shrunk to mitigate gravity-induced distortion. These small scales make it impossible to observe the inertial and pinning processes in detail. Instead, in the International Space Station (ISS), astronaut Luca Parmitano slowly extruded water spheres until they touched any of nine capillary plates. The 12mm diameter droplets were large enough for high-speed GX1050C video cameras on top and side to visualize details near individual capillaries, and long enough to observe dynamics of the entire imbibition process. To investigate the role of contact pinning, a text matrix was produced which consisted nine kinds of porous capillary plates made of gold-coated brass treated with Self-Assembled Monolayers (SAM) that fixed advancing and receding contact angles to known values. In the ISS, long-term microgravity allowed unambiguous observations of the role of contact line pinning during the inertial phase of imbibition. The high-speed videos of spreading and imbibition on the porous plates were analyzed using computer vision software to calculate the radius of the droplet contact patch with the plate and height of the droplet vs time. These observations are compared with numerical simulations and with data that we obtained at the ESA ZARM free-fall tower in Bremen with a unique mechanism producing relatively large water spheres and similarity in the results were observed. The data obtained from the ISS can be used as a benchmark for further numerical simulations in the field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=droplet%20imbibition" title="droplet imbibition">droplet imbibition</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophilic%20surface" title=" hydrophilic surface"> hydrophilic surface</a>, <a href="https://publications.waset.org/abstracts/search?q=inertial%20phase" title=" inertial phase"> inertial phase</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20medium" title=" porous medium"> porous medium</a> </p> <a href="https://publications.waset.org/abstracts/123483/inertial-spreading-of-drop-on-porous-surfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123483.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">139</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">72</span> Severe Post Operative Gas Gangrene of the Liver: Off-Label Treatment by Percutaneous Radiofrequency Ablation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luciano%20Tarantino">Luciano Tarantino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gas gangrene is a rare, severe infection with a very high mortality rate caused by Clostridium species. The infection causes a non-suppurative localized producing gas lesion from which harmful toxins that impair the inflammatory response cause vessel damage and multiple organ failure. Gas gangrene of the liver is very rare and develops suddenly, often as a complication of abdominal surgery and liver transplantation. The present paper deals with a case of gas gangrene of the liver that occurred after percutaneous MW ablation of hepatocellular carcinoma, resulting in progressive liver necrosis and multi-organ failure in spite of specific antibiotics administration. The patient was successfully treated with percutaneous Radiofrequency ablation. Case report: Female, 76 years old, Child A class cirrhosis, treated with synchronous insertion of 3 MW antennae for large HCC (5.5 cm) in the VIII segment. 24 hours after treatment, the patient was asymptomatic and left the hospital . 2 days later, she complained of fever, weakness, abdominal swelling, and pain. Abdominal US detected a 2.3 cm in size gas-containing area, eccentric within the large (7 cm) ablated area. The patient was promptly hospitalized with the diagnosis of anaerobic liver abscess and started antibiotic therapy with Imipenem/cilastatine+metronidazole+teicoplanine. On the fourth day, the patient was moved to the ICU because of dyspnea, congestive heart failure, atrial fibrillation, right pleural effusion, ascites, and renal failure. Blood tests demonstrated severe leukopenia and neutropenia, anemia, increased creatinine and blood nitrogen, high-level FDP, and high INR. Blood cultures were negative. At US, unenhanced CT, and CEUS, a progressive enlargement of the infected liver lesion was observed. Percutaneous drainage was attempted, but only drops of non-suppurative brownish material could be obtained. Pleural and peritoneal drainages gave serosanguineous muddy fluid. The Surgeon and the Anesthesiologist excluded any indication of surgical resection because of the high perioperative mortality risk. Therefore, we asked for the informed consent of the patient and her relatives to treat the gangrenous liver lesion by percutaneous Ablation. Under conscious sedation, percutaneous RFA of GG was performed by double insertion of 3 cool-tip needles (Covidien LDT, USA ) into the infected area. The procedure was well tolerated by the patient. A dramatic improvement in the patient's condition was observed in the subsequent 24 hours and thereafter. Fever and dyspnea disappeared. Normalization of blood tests, including creatinine, was observed within 4 days. Heart performance improved, 10 days after the RFA the patient left the hospital and was followed-up with weekly as an outpatient for 2 months and every two months thereafter. At 18 months follow-up, the patient is well compensated (Child-Pugh class B7), without any peritoneal or pleural effusion and without any HCC recurrence at imaging (US every 3 months, CT every 6 months). Percutaneous RFA could be a valuable therapy of focal GG of the liver in patients non-responder to antibiotics and when surgery and liver transplantation are not feasible. A fast and early indication is needed in case of rapid worsening of patient's conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liver%20tumor%20ablation" title="liver tumor ablation">liver tumor ablation</a>, <a href="https://publications.waset.org/abstracts/search?q=interventional%20ultrasound" title=" interventional ultrasound"> interventional ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20infection" title=" liver infection"> liver infection</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20gangrene" title=" gas gangrene"> gas gangrene</a>, <a href="https://publications.waset.org/abstracts/search?q=radiofrequency%20ablation" title=" radiofrequency ablation"> radiofrequency ablation</a> </p> <a href="https://publications.waset.org/abstracts/172799/severe-post-operative-gas-gangrene-of-the-liver-off-label-treatment-by-percutaneous-radiofrequency-ablation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172799.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">78</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">71</span> Comparative Study in Treatment of Distal Humerus Fracture with Lateral Column Plate Percutaneous Medial Screw and Intercondylar Screw</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sameer%20Gupta">Sameer Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Prant%20Gupta"> Prant Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Context: Fractures in the distal humerus are complex and challenging injuries for orthopaedic surgeons that can be effectively treated with open reduction and internal fixation. Aims: The study analyses clinical outcomes in patients with intra-articular distal humerus fractures (AO type 13 C3 excluded) treated using a different method of fixation ( LCPMS). Subject and Methods: A study was performed, and the author's personal experiences were reported. Thirty patients were treated using an intercondylar screw with lateral column plating and percutaneous medial column screw fixation. Detailed analysis was done for functional outcomes (average arc of motion, union rate, and complications). Statistical Analysis Used: SPSS software version 22.0 was used for statistical analysis. Results: In our study, at the end of 6 months, Overall good to excellent results were achieved in 28 patients out of 30 after analysis on the basis of MEP score. The majority of patients regained full arc of motion, achieved fracture union without any major complications, and were able to perform almost all activities of daily living (which required good elbow joint movements and functions). Conclusion: We concluded that this novel method provides adequate stability and anatomical reconstruction with an early union rate observed at the end of 6 months. Excellent functional outcome was observed in almost all the patients because of less operating time and initiation of early physiotherapy, as most of the patients experienced mild nature of pain post-surgery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intra%20arricular%20distal%20humerus%20fracture" title="intra arricular distal humerus fracture">intra arricular distal humerus fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=percutaneous%20medial%20screw" title=" percutaneous medial screw"> percutaneous medial screw</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20column%20plate" title=" lateral column plate"> lateral column plate</a>, <a href="https://publications.waset.org/abstracts/search?q=arc%20of%20motion" title=" arc of motion"> arc of motion</a> </p> <a href="https://publications.waset.org/abstracts/182202/comparative-study-in-treatment-of-distal-humerus-fracture-with-lateral-column-plate-percutaneous-medial-screw-and-intercondylar-screw" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182202.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">60</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">70</span> Clinical Outcomes After Radiological Management of Varicoceles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eric%20Lai">Eric Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Lorger"> Sarah Lorger</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Eisinger"> David Eisinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Waugh"> Richard Waugh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Percutaneous embolization of varicoceles has shown similar outcomes to surgery. However, there are advantages of radiological intervention as patients are not exposed to general anaesthesia, experience a quicker recovery and face a lower risk of major complications. Radiological interventions are also preferable after a failed surgical approach. We evaluate clinical outcomes of percutaneous embolization at a tertiary hospital in Sydney, Australia. Methods: Retrospective case series without a control group from a single site (Royal Prince Alfred Hospital, Sydney, Australia). A data search was performed on the interventional radiology database with the word “varicocele” between February 2017 and March 2022. 62 patients were identified. Each patient file was reviewed and included in the study if they met the inclusion criteria. Results: A total of 56 patients were included. 6 patients were excluded as they did not receive intervention after the initial diagnostic venography. Technical success was 100%. Complications were seen in 3 patients (5.3%). The complications included post-procedural pain and fever, venous perforation with no clinical adverse outcome, and a mild allergic reaction to contrast. Recurrence occurred in 3 patients (5.6%), all of whom received a successful second procedure. DISCUSSION: This study demonstrates comparable rates of technical success, complication rate and recurrence to other studies in the literature. When compared to surgical outcomes, the results were also similar. The main limitation is multiple patients lack long-term follow-up beyond 1 year, resulting in potential underestimation of the recurrence rate. Conclusion: Percutaneous embolization of varicocele is a safe alternative to surgical intervention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=varicocele" title="varicocele">varicocele</a>, <a href="https://publications.waset.org/abstracts/search?q=interventional%20radiology" title=" interventional radiology"> interventional radiology</a>, <a href="https://publications.waset.org/abstracts/search?q=urology" title=" urology"> urology</a>, <a href="https://publications.waset.org/abstracts/search?q=radiology" title=" radiology"> radiology</a> </p> <a href="https://publications.waset.org/abstracts/178551/clinical-outcomes-after-radiological-management-of-varicoceles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178551.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">71</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">69</span> Assessing the Accessibility to Primary Percutaneous Coronary Intervention</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tzu-Jung%20Tseng">Tzu-Jung Tseng</a>, <a href="https://publications.waset.org/abstracts/search?q=Pei-Hsuen%20Han"> Pei-Hsuen Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsung-Hsueh%20Lu"> Tsung-Hsueh Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Ensuring patients with ST-elevation myocardial infarction (STEMI) access to hospitals that could perform percutaneous coronary intervention (PCI) in time is an important concern of healthcare managers. One commonly used the method to assess the coverage of population access to PCI hospital is the use GIS-estimated linear distance (crow's fly distance) between the district centroid and the nearest PCI hospital. If the distance is within a given distance (such as 20 km), the entire population of that district is considered to have appropriate access to PCI. The premise of using district centroid to estimate the coverage of population resident in that district is that the people live in the district are evenly distributed. In reality, the population density is not evenly distributed within the administrative district, especially in rural districts. Fortunately, the Taiwan government released basic statistical area (on average 450 population within the area) recently, which provide us an opportunity to estimate the coverage of population access to PCI services more accurate. Objectives: We aimed in this study to compare the population covered by a give PCI hospital according to traditional administrative district versus basic statistical area. We further examined if the differences between two geographic units used would be larger in a rural area than in urban area. Method: We selected two hospitals in Tainan City for this analysis. Hospital A is in urban area, hospital B is in rural area. The population in each traditional administrative district and basic statistical area are obtained from Taiwan National Geographic Information System, Ministry of Internal Affairs. Results: Estimated population live within 20 km of hospital A and B was 1,515,846 and 323,472 according to traditional administrative district and was 1,506,325 and 428,556 according to basic statistical area. Conclusion: In urban area, the estimated access population to PCI services was similar between two geographic units. However, in rural areas, the access population would be overestimated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accessibility" title="accessibility">accessibility</a>, <a href="https://publications.waset.org/abstracts/search?q=basic%20statistical%20area" title=" basic statistical area"> basic statistical area</a>, <a href="https://publications.waset.org/abstracts/search?q=modifiable%20areal%20unit%20problem%20%28MAUP%29" title=" modifiable areal unit problem (MAUP)"> modifiable areal unit problem (MAUP)</a>, <a href="https://publications.waset.org/abstracts/search?q=percutaneous%20coronary%20intervention%20%28PCI%29" title=" percutaneous coronary intervention (PCI)"> percutaneous coronary intervention (PCI)</a> </p> <a href="https://publications.waset.org/abstracts/61904/assessing-the-accessibility-to-primary-percutaneous-coronary-intervention" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61904.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">458</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">68</span> Microscopic Analysis of Bulk, High-Tc Superconductors by Transmission Kikuchi Diffraction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anjela%20Koblischka-Veneva">Anjela Koblischka-Veneva</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20R.%20Koblischka"> Michael R.

This type of analysis of the EBSD/TKD data is, therefore, also important for other material systems, where nanoparticles are embedded in a matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electron%20backscatter%20Diffraction" title="electron backscatter Diffraction">electron backscatter Diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20Kikuchi%20diffraction" title=" transmission Kikuchi diffraction"> transmission Kikuchi diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=YBCO" title=" YBCO"> YBCO</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/126917/microscopic-analysis-of-bulk-high-tc-superconductors-by-transmission-kikuchi-diffraction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126917.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">128</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">66</span> Numerical Study of Homogeneous Nanodroplet Growth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20B.%20Q.%20Tran">S. B. Q. Tran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drop condensation is the phenomenon that the tiny drops form when the oversaturated vapour present in the environment condenses on a substrate and makes the droplet growth. Recently, this subject has received much attention due to its applications in many fields such as thin film growth, heat transfer, recovery of atmospheric water and polymer templating. In literature, many papers investigated theoretically and experimentally in macro droplet growth with the size of millimeter scale of radius. However few papers about nanodroplet condensation are found in the literature especially theoretical work. In order to understand the droplet growth in nanoscale, we perform the numerical simulation work to study nanodroplet growth. We investigate and discuss the role of the droplet shape and monomer diffusion on drop growth and their effect on growth law. The effect of droplet shape is studied by doing parametric studies of contact angle and disjoining pressure magnitude. Besides, the effect of pinning and de-pinning behaviours is also studied. We investigate the axisymmetric homogeneous growth of 10–100 nm single water nanodroplet on a substrate surface. The main mechanism of droplet growth is attributed to the accumulation of laterally diffusing water monomers, formed by the absorption of water vapour in the environment onto the substrate. Under assumptions of quasi-steady thermodynamic equilibrium, the nanodroplet evolves according to the augmented Young–Laplace equation. Using continuum theory, we model the dynamics of nanodroplet growth including the coupled effects of disjoining pressure, contact angle and monomer diffusion with the assumption of constant flux of water monomers at the far field. The simulation result is validated by comparing with the published experimental result. For the case of nanodroplet growth with constant contact angle, our numerical results show that the initial droplet growth is transient by monomer diffusion. When the flux at the far field is small, at the beginning, the droplet grows by the diffusion of initially available water monomers on the substrate and after that by the flux at the far field. In the steady late growth rate of droplet radius and droplet height follow a power law of 1/3, which is unaffected by the substrate disjoining pressure and contact angle. However, it is found that the droplet grows faster in radial direction than high direction when disjoining pressure and contact angle increase. The simulation also shows the information of computational domain effect in the transient growth period. When the computational domain size is larger, the mass coming in the free substrate domain is higher. So the mass coming in the droplet is also higher. The droplet grows and reaches the steady state faster. For the case of pinning and de-pinning droplet growth, the simulation shows that the disjoining pressure does not affect the droplet radius growth law 1/3 in steady state. However the disjoining pressure modifies the growth rate of the droplet height, which then follows a power law of 1/4. We demonstrate how spatial depletion of monomers could lead to a growth arrest of the nanodroplet, as observed experimentally. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=augmented%20young-laplace%20equation" title="augmented young-laplace equation">augmented young-laplace equation</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20angle" title=" contact angle"> contact angle</a>, <a href="https://publications.waset.org/abstracts/search?q=disjoining%20pressure" title=" disjoining pressure"> disjoining pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=nanodroplet%20growth" title=" nanodroplet growth"> nanodroplet growth</a> </p> <a href="https://publications.waset.org/abstracts/42068/numerical-study-of-homogeneous-nanodroplet-growth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42068.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">272</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">65</span> Preliminary Short-Term Results of a Population of Patients Treated with Mitraclip Therapy: One Center Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rossana%20Taravella">Rossana Taravella</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilberto%20M.%20Cellura"> Gilberto M.

We describe in this article the preliminary results of primary effectiveness endpoint. Background: Percutaneous Mitral Repair is being developed to treat severe mitral regurgitation (MR), with increasing real-world cases of functional MR (FMR). In the EVEREST (Endovascular Valve Edge-to-Edge Repair Study)II trial, the percutaneous device showed superior safety but less reduction in MR at 1year. 4-year outcomes from EVEREST II trial showed no difference in the prevalence of moderate-severe and severe MR or mortality at 4years between surgical mitral repair and percutaneous approach. Methods: We analysed retrospectively collected data from one center experience in Italy enrolled from January 2011 to December 2016. The study included 62 patients [mean age 74±11years, 43 men (69%)] with MR of at least grade3+. Most of the patients had functional MR, were in New York Heart Association (NYHA) functional class III or IV, with a large portion (78%) of mild-to-moderate Tricuspid Regurgitation (TR). One or more clips were implanted in 67 procedures (62 patients). Results and Conclusions: Severity of MR was reduced in all successfully treated patients,54(90%) were discharged with MR≤2+ (primary effectiveness endpoint). Clinical 1-month follow-up data showed an improvement in NYHA functional class (42 patients (70%) in NYHA class I-II). 60 of 62 (97 %) successfully treated patients were free from death and mitral valve surgery at 1-month follow-up. MitraClip therapy reduces functional MR with acute MR reduction to <2+ in the great majority of patients, with a large freedom from death, surgery or recurrent MR in a great portion of patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MitraClip" title="MitraClip">MitraClip</a>, <a href="https://publications.waset.org/abstracts/search?q=mitral%20regurgitation" title=" mitral regurgitation"> mitral regurgitation</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20valves" title=" heart valves"> heart valves</a>, <a href="https://publications.waset.org/abstracts/search?q=catheter-based%20therapy" title=" catheter-based therapy"> catheter-based therapy</a> </p> <a href="https://publications.waset.org/abstracts/68742/preliminary-short-term-results-of-a-population-of-patients-treated-with-mitraclip-therapy-one-center-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68742.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">295</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">64</span> Evaluation of Percutaneous Tube Thoracostomy Performed by Trainee in Both Trauma and Non-Trauma Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kulsum%20Maula">Kulsum Maula</a>, <a href="https://publications.waset.org/abstracts/search?q=Md%20Kamrul%20Alam"> Md Kamrul Alam</a>, <a href="https://publications.waset.org/abstracts/search?q=Md%20Ibrahim%20Khalil"> Md Ibrahim Khalil</a>, <a href="https://publications.waset.org/abstracts/search?q=Md%20Nazmul%20Hasan"> Md Nazmul Hasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Omar%20Faruq"> Mohammad Omar Faruq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Percutaneous Tube Thoracostomy (PTT) is an invasive procedure that can save a life now and then in different traumatic and non-traumatic conditions. But still, it is an enigma; how our trainee surgeons are at home in this procedure. Objectives: To evaluate the outcome of the percutaneous tube thoracostomy performed by trainees in both trauma and non-trauma patients. Study design: Prospective, Observational Study. The duration of the study was September 2018 to February 2019. Methods: All patients who need PTT in traumatic and non-traumatic conditions were selected by purposive sampling. Thereafter, they were scrutinized according to eligibility criteria and 96 patients were finalized. A pre-tested, observation-based, peer-reviewed data collection sheet was prepared before the study. Data regarding clinical and surgical outcome profiles were recorded. Data were compiled, edited, and analyzed. Results: Among 96 patients, the highest 32.29% belonged to age group 31-40 years and the lowest 9.37% belonged to the age group ≤20. The mean age of the respondents was 29.19±9.81. We found out of 96 patients, 70(72.91%) were indicated PTT for traumatic conditions and the rest 26(27.08%) were indicated PTT for non-traumatic chest conditions, where 36(37.5%) had simple penumothorax, 21(21.87%) haemothorax, 14(14.58%) massive pleural effusion, 13(13.54%) tension pneumothorax, 10(10.41%) haemopneumothorax, and 2(2.08%) had pyothorax respectively. In 53.12% of patients had right-sided intercostal chest tube (ICT) insertion, whereas 46.87% had left-sided ICT insertion. In our study, 89.55 % of the tube was placed at the normal anatomical position. Besides, 10.41% of tube thoracostomy were performed deviated from anatomical site. Among 96 patients 62.5% patients had length of incision 2-3cm, 35.41% had >3cm and 2.08% had <2cm respectively. Out of 96 patients, 75(78.13%) showed uneventful outcomes, whereas 21(21.87%) had complications, including 11.15%(11) each had wound infection, 4.46%(4) subcutaneous emphysema, 4.28%(3) drain auto expulsion, 2.85%(2) hemorrhage, 1.45%(1) had a non-functioning drain and empyema with ascending infection respectively (p=<0.05). Conclusion: PTT is a life-saving procedure that is most frequently implemented in chest trauma patients in our country. In the majority of cases, the outcome of PTT was uneventful (78.13). Besides this, more than one-third of patients had a length of incision more than 3 cm that needed extra stitches and 10.41% of cases of PTT were placed other than the normal anatomical site. Trainees of Dhaka Medical College Hospitals are doing well in their performance of PTT insertion, but still, some anatomical orientations are necessary to avoid operative and post-operative complications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PTT" title="PTT">PTT</a>, <a href="https://publications.waset.org/abstracts/search?q=trainee" title=" trainee"> trainee</a>, <a href="https://publications.waset.org/abstracts/search?q=trauma" title=" trauma"> trauma</a>, <a href="https://publications.waset.org/abstracts/search?q=non-chest%20trauma%20patients" title=" non-chest trauma patients"> non-chest trauma patients</a> </p> <a href="https://publications.waset.org/abstracts/149771/evaluation-of-percutaneous-tube-thoracostomy-performed-by-trainee-in-both-trauma-and-non-trauma-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149771.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">121</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">63</span> Conservative Treatment Versus Percutaneous Wire Fixation in treatment of Distal Radial Fracture in Elderly</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelfatah%20Elsenosy">Abdelfatah Elsenosy</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Ebrahim"> Mahmoud Ebrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Distal radius fractures are commonly encountered in orthopedic practice, especially in elderly patients. A number of clinical papers have supported the idea that anatomic restoration of the distal end of the radius is essential to gain superior results. Aim and objectives: The aim of the study is to systematically review the literature for the management of distal end radius in elderly persons (conservative treatment versus percutaneous wire fixation) as regards radiological and functional outcomes. Subjects and methods: Studies were identified from the Medline, Cochrane, EMBASE, and Google Scholar databases were searched until 2019 using combinations of the following search terms: distal radius fracture, conservative treatment, non-operative treatment, and nonsurgical treatment, surgical treatment, operative, elderly, and older. Reference lists of relevant studies were manually searched. Results: There was no statistical significance difference between CI and PKF groups’ frequency of complication in all of the selected studies. Based on the results, we recommend more analysis regarding every parameter of the radiographic and functional results and specific complications related to each fixation need to be accomplished, which requires more Randomized controlled trials (RCTs) with high quality. Conclusion: Surgical treatment seems to be more effective distal radius fracture compared with conservative treatment when the radiographic outcomes were analyzed, and no significant differences were detected in the functional outcomes and complication rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radius" title="radius">radius</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical" title=" surgical"> surgical</a>, <a href="https://publications.waset.org/abstracts/search?q=RCTs" title=" RCTs"> RCTs</a>, <a href="https://publications.waset.org/abstracts/search?q=conservative" title=" conservative"> conservative</a>, <a href="https://publications.waset.org/abstracts/search?q=radiographic" title=" radiographic"> radiographic</a>, <a href="https://publications.waset.org/abstracts/search?q=outcomes" title=" outcomes"> outcomes</a>, <a href="https://publications.waset.org/abstracts/search?q=orthopedic" title=" orthopedic"> orthopedic</a> </p> <a href="https://publications.waset.org/abstracts/144226/conservative-treatment-versus-percutaneous-wire-fixation-in-treatment-of-distal-radial-fracture-in-elderly" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144226.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">146</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">62</span> Assessing the Risk of Pressure Injury during Percutaneous Nephrolithotomy Using Pressure Mapping</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jake%20Tempo">Jake Tempo</a>, <a href="https://publications.waset.org/abstracts/search?q=Taylor%20Smithurst"> Taylor Smithurst</a>, <a href="https://publications.waset.org/abstracts/search?q=Jen%20Leah"> Jen Leah</a>, <a href="https://publications.waset.org/abstracts/search?q=Skye%20Waddingham"> Skye Waddingham</a>, <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Catlin"> Amanda Catlin</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Cetti"> Richard Cetti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Percutaneous nephrolithotomy (PCNL) is the gold-standard procedure for removing large or complex renal stones. Many operating positions can be used, and the debate over the ideal position continues. PCNL can be a long procedure during which patients can sustain pressure injuries. These injuries are often underreported in the literature. Interface pressure mapping records the pressure loading between a surface and the patient. High pressures with prolonged loading result in ischaemia, muscle deformation, and reperfusion which can cause skin breakdown and muscular injury. We compared the peak pressure indexes of common PCNL positions to identify positions which may be at high risk of pressure injuries. We hope the data can be used to adapt high-risk positions so that the PPI can be lessened by either adapting the positions or by using adjuncts to lower PPI. Materials and Methods: We placed a 23-year-old male subject in fourteen different PCNL positions while performing interface pressure mapping. The subject was 179 cm with a weight of 63.3 kg, BMI 19.8kg/m². Results: Supine positions had a higher mean PPI (119mmHg (41-137)) compared to prone positions (64mmHg (32-89)) (p=0.046 two tailed t-test). The supine flexed position with a bolster under the flank produced the highest PPI (194mmHg), and this was at the sacrum. Peak pressure indexes >100mmHg were recorded in eight PCNL positions. Conclusion: Supine PCNL positions produce higher PPI than prone PCNL positions. Our study shows where ‘at risk’ bony prominences are for each PCNL position. Surgeons must ensure these areas are protected during prolonged operations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PCNL" title="PCNL">PCNL</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20ulcer" title=" pressure ulcer"> pressure ulcer</a>, <a href="https://publications.waset.org/abstracts/search?q=interface%20pressure%20mapping" title=" interface pressure mapping"> interface pressure mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a> </p> <a href="https://publications.waset.org/abstracts/145163/assessing-the-risk-of-pressure-injury-during-percutaneous-nephrolithotomy-using-pressure-mapping" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145163.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">83</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">61</span> Retrospective Analysis Demonstrates No Difference in Percutaneous Native Renal Biopsy Adequacy Between Nephrologists and Radiologists in University Hospital Crosshouse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicole%20Harley">Nicole Harley</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Eid"> Mahmoud Eid</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdurahman%20Tarmal"> Abdurahman Tarmal</a>, <a href="https://publications.waset.org/abstracts/search?q=Vishal%20Dey"> Vishal Dey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Histological sampling plays an integral role in the diagnostic process of renal diseases. Percutaneous native renal biopsy is typically performed under ultrasound guidance, with this service usually being provided by nephrologists. In some centers, there is a role for radiologists in performing renal biopsies. Previous comparative studies have demonstrated non-inferiority between outcomes of percutaneous native renal biopsies performed by nephrologists compared with radiologists. We sought to compare biopsy adequacy between nephrologists and radiologists in University Hospital Crosshouse. The online system SERPR (Scottish Electronic Renal Patient Record) contains information pertaining to patients who have undergone renal biopsies. An online search was performed to acquire a list of all patients who underwent renal biopsy between 2013 and 2020 in University Hospital Crosshouse. 355 native renal biopsies were performed in total across this 7-year period. A retrospective analysis was performed on these cases, with records and reports being assessed for: the total number of glomeruli obtained per biopsy, whether the number of glomeruli obtained was adequate for diagnosis, as per an internationally agreed standard, and whether a histological diagnosis was achieved. Nephrologists performed 43.9% of native renal biopsies (n=156) and radiologists performed 56.1% (n=199). The mean number of glomeruli obtained by nephrologists was 17.16+/-10.31. The mean number of glomeruli obtained by radiologists was 18.38+/-10.55. T-test demonstrated no statistically significant difference between specialties comparatively (p-value 0.277). Native renal biopsies are required to obtain at least 8 glomeruli to be diagnostic as per internationally agreed criteria. Nephrologists met these criteria in 88.5% of native renal biopsies (n=138) and radiologists met this criteria in 89.5% (n=178). T-test and Chi-squared analysis demonstrate there was no statistically significant difference between the specialties comparatively (p-value 0.663 and 0.922, respectively). Biopsies performed by nephrologists yielded tissue that was diagnostic in 91.0% (n=142) of sampling. Biopsies performed by radiologists yielded tissue that was diagnostic in 92.4% (n=184) of sampling. T-test and Chi-squared analysis demonstrate there was no statistically significant difference between the specialties comparatively (p-value 0.625 and 0.889, respectively). This project demonstrates that at University Hospital Crosshouse, there is no statistical difference between radiologists and nephrologists in terms of glomeruli acquisition or samples achieving a histological diagnosis. Given the non-inferiority between specialties demonstrated by previous studies and this project, this evidence could support the restructuring of services to allow more renal biopsies to be performed by renal services and allow reallocation of radiology department resources. <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=medical%20imaging" title=" medical imaging"> medical imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=nephrology" title=" nephrology"> nephrology</a>, <a href="https://publications.waset.org/abstracts/search?q=radiology" title=" radiology"> radiology</a> </p> <a href="https://publications.waset.org/abstracts/157526/retrospective-analysis-demonstrates-no-difference-in-percutaneous-native-renal-biopsy-adequacy-between-nephrologists-and-radiologists-in-university-hospital-crosshouse" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157526.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">81</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">60</span> Early versus Late Percutaneous Tracheostomy in Critically Ill Adult Mechanically Ventilated Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamel%20Abd%20Elaziz%20Mohamed">Kamel Abd Elaziz Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Yehia%20Mousa"> Ahmed Yehia Mousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Samir%20ElSawy"> Ahmed Samir ElSawy</a>, <a href="https://publications.waset.org/abstracts/search?q=Adel%20Mohamed%20Saleem"> Adel Mohamed Saleem </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Critically ill patients frequently require tracheostomy to simplify long term air way management. While tracheostomy indications have remained unchanged, the timing of elective tracheostomy for the ventilated patient has been questioned. Aim of the work: This study was performed to compare the differences between early and late percutaneous dilatational tracheostomy (PDT) regarding, mechanical ventilation duration (MVD), length of ICU stay, length of hospital stay, incidence of ventilator associated pneumonia and hospital outcome. Patients and methods: Forty patients who met the inclusion criteria were randomly divided into early PDT who had the tracheostomy within the first 10 days of mechanical ventilation (MV) and the late PDT who had the tracheostomy after 10 days of MV. On admission, demographic data and Acute Physiology and Chronic ill Health II and GCS were collected. The duration of mechanical ventilation, ICU length of stay (LOS) and hospital LOS were all calculated. Results: Total of 40 patients were randomized to either early PDT (n= 20) or late PDT (n= 20). There were no significant differences between both groups regarding demographic data or the scores: APACHE II (22.75± 7 vs 24.35 ± 8) and GCS (6.10 ±2 vs 7.10 ± 2.71). An early PDT showed fewer complications vs late procedure, however it was insignificant. There were significant differences between the two groups regarding mean (MVD) which was shorter in early PDT than the late PDT group (32.2± 10.5) vs (20.6 ± 13 days; p= 0.004). Mean ICU stay was shorter in early PDT than late PDT (21 .0± 513.4) vs (40.15 ±12.7 days; p 6 0.001). Mean hospital stay was shorter in early PDT than late PDT (34.60± 18.37) vs (55.60± 25.73 days; p=0.005). Patients with early PDT suffered less sepsis and VAP than late PDT, there was no difference regarding the mortality rate between the two groups. Conclusion: Early PDT is recommended for patients who require prolonged tracheal intubation in the ICU as outcomes like the duration of mechanical ventilation length of ICU stay and hospital stay were significantly shorter in early tracheostomy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intensive%20care%20unit" title="intensive care unit">intensive care unit</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20PDT" title=" early PDT"> early PDT</a>, <a href="https://publications.waset.org/abstracts/search?q=late%20PDT" title=" late PDT"> late PDT</a>, <a href="https://publications.waset.org/abstracts/search?q=intubation" title=" intubation"> intubation</a> </p> <a href="https://publications.waset.org/abstracts/19548/early-versus-late-percutaneous-tracheostomy-in-critically-ill-adult-mechanically-ventilated-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19548.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">600</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">59</span> Ozone Therapy for Disc Herniation: A Non-surgical Option</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahzad%20Karim%20Bhatti">Shahzad Karim Bhatti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Ozone is a combination of oxygen and can be used in treatment of low back pain due to herniated disc. It is a minimally invasive procedure using biochemical properties of ozone resulting in reduced volume of disc and inflammation resulting in significant pain relief. Aim: The purpose of this study was to evaluate the effectiveness of ozone therapy in combination with peri-ganglionic injection of local anesthetic and corticosteroid. Material and Methods: This retrospective study was done at the Interventional Radiology Department of Mayo Hospital, Lahore. A total of 49000 patients were included from January 2008 to March 2022. All the patients presented with clinical signs and symptoms of lumber disc herniation, which was confirmed by a MRI scan of the lumbar sacral spine. The pain reduction was calculated using modified MacNab method. All the patients underwent percutaneous injection of ozone at a concentration of 27 micrograms/ml to lumber disc under fluoroscopic guidance with combination of local anesthetic and corticosteroid in peri-ganglionic space. Results were evaluated by two expert observers who were blinded to patient treatment. Results A satisfactory therapeutic outcome was obtained. 55% of the patients showed complete recovery with resolution of symptoms. 20% of the patients complained of occasional episodic pain with no limitation of occupational activity. 15% of cases showed insufficient improvement. 5% of cases had insufficient improvement and went for surgery. 10% of cases never turned up after the first visit. Conclusion Intradiscal ozone for the treatment of herniated discs has revolutionized percutaneous approach to nerve root compression making it safer, economical and easier to repeat without any side effects than treatments currently used in Pakistan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pain" title="pain">pain</a>, <a href="https://publications.waset.org/abstracts/search?q=prolapse" title=" prolapse"> prolapse</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozone" title=" Ozone"> Ozone</a>, <a href="https://publications.waset.org/abstracts/search?q=backpain" title=" backpain"> backpain</a> </p> <a href="https://publications.waset.org/abstracts/188838/ozone-therapy-for-disc-herniation-a-non-surgical-option" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188838.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">27</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">58</span> A Comparison of Outcomes of Endoscopic Retrograde Cholangiopancreatography vs. Percutaneous Transhepatic Biliary Drainage in the Management of Obstructive Jaundice from Hepatobiliary Tuberculosis: The Philippine General Hospital Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Margaret%20Elaine%20J.%20Villamayor">Margaret Elaine J.

Methodology: This is a cross-sectional study involving patients from PGH who underwent biliary drainage from HBTB from January 2009 to June 2014. HBTB was defined as having evidence of TB (culture, smear, PCR, histology) or clinical diagnosis with the triad of jaundice, fever, and calcifications on imaging with other causes of jaundice excluded. The primary outcome was successful drainage and secondary outcomes were mean hospital stay and complications. Simple logistic regression was used to identify factors associated with success of drainage, z-test for two proportions to compare outcomes of ERCP versus PTBD and t-test to compare mean hospital stay post-procedure. Results: There were 441 patients who underwent ERCP and PTBD, 19 fulfilled the inclusion criteria. 11 underwent ERCP while 8 had PTBD. There were more successful cases in PTBD versus ERCP but this was not statistically significant (p-value 0.3615). Factors such as age, gender, location and nature of obstruction, vices, coexisting pulmonary or other extrapulmonary TB and presence of portal hypertension did not affect success rates in these patients. The PTBD group had longer mean hospital stay but this was not significant (p-value 0.1880). There were no complications reported in both groups. Conclusion: HBTB comprises 4.3% of the patients undergoing biliary drainage in PGH. Both ERCP and PTBD are equally safe and effective in the management of biliary obstruction from HBTB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-sectional" title="cross-sectional">cross-sectional</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatobiliary%20tuberculosis" title=" hepatobiliary tuberculosis"> hepatobiliary tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=obstructive%20jaundice" title=" obstructive jaundice"> obstructive jaundice</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20retrograde%20cholangiopancreatography" title=" endoscopic retrograde cholangiopancreatography"> endoscopic retrograde cholangiopancreatography</a>, <a href="https://publications.waset.org/abstracts/search?q=percutaneous%20transhepatic%20biliary%20drainage" title=" percutaneous transhepatic biliary drainage "> percutaneous transhepatic biliary drainage </a> </p> <a href="https://publications.waset.org/abstracts/26346/a-comparison-of-outcomes-of-endoscopic-retrograde-cholangiopancreatography-vs-percutaneous-transhepatic-biliary-drainage-in-the-management-of-obstructive-jaundice-from-hepatobiliary-tuberculosis-the-philippine-general-hospital-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26346.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">444</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">57</span> Nutrition Intervention for Spinal Cord Injury in Critical Care</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dina%20Muharib">Dina Muharib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Specific metabolic challenges are present following spinal cord injury.

Provisional T-stenting is currently one of the recommended techniques. The aim was to assess optimal methods of treatment in the era of drug-eluting stents (DES). Methods: The regis-try consisted of data from 1916 patients treated with coronary percutaneous interventions (PCI) using either first- or second-generation DES. Patients with bifurcation lesion entered the analysis. Major adverse cardiac and cardiovascular events (MACCE) were assessed at one year of follow-up and comprised of death, acute myocardial infarction (AMI), repeated PCI (re-PCI) of target ves-sel and stroke. Results: Of 1916 registry patients, 204 patients (11%) were diagnosed with bifurcation lesion >50% and entered the analysis. The most commonly used technique was provi-sional T-stenting (141 patients, 69%). Optimization with kissing-balloons technique was performed in 45 patients (22%). In 59 patients (29%) second-generation DES was implanted, while in 112 pa-tients (55%), first-generation DES was used. In 33 patients (16%) both types of DES were used. The procedure success rate (TIMI 3 flow) was achieved in 98% of patients. In one-year follow-up, there were 39 MACCE (19%) (9 deaths, 17 AMI, 16 re-PCI and 5 strokes). Provisional T-stenting resulted in similar rate of MACCE to other techniques (16% vs. 5%, p=0.27) and similar occurrence of re-PCI (6% vs. 2%, p=0.78). The results of post-PCI kissing-balloon technique gave equal out-comes with 3% vs. 16% of MACCE in patients in whom no optimization technique was used (p=0.39). The type of implanted DES (second- vs. first-generation) had no influence on MACCE (4% vs 14%, respectively, p=0.12) and re-PCI (1.7% vs. 51% patients, respectively, p=0.28). Con-clusions: The treatment of bifurcation lesions with PCI represent high-risk procedures with high rate of MACCE. Stenting technique, optimization of PCI and the generation of implanted stent should be personalized for each case to balance risk of the procedure. In this setting, the operator experience might be the factor of better outcome, which should be further investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coronary%20bifurcation" title="coronary bifurcation">coronary bifurcation</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20eluting%20stents" title=" drug eluting stents"> drug eluting stents</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20follow-up" title=" long-term follow-up"> long-term follow-up</a>, <a href="https://publications.waset.org/abstracts/search?q=percutaneous%20coronary%20interventions" title=" percutaneous coronary interventions"> percutaneous coronary interventions</a> </p> <a href="https://publications.waset.org/abstracts/76395/long-term-results-of-coronary-bifurcation-stenting-with-drug-eluting-stents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76395.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">204</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">55</span> Myocardial Reperfusion Injury during Percutaneous Coronary Intervention in Patient with Triple-Vessel Disease in Limited Resources Hospital: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fanniyah%20Anis">Fanniyah Anis</a>, <a href="https://publications.waset.org/abstracts/search?q=Bram%20Kilapong"> Bram Kilapong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Myocardial reperfusion injury is defined as the cellular damage that results from a period of ischemia, followed by the reestablishment of the blood supply to the infarcted tissue. Ventricular tachycardia is one of the most commonly encountered reperfusion arrhythmia as one of the types of myocardial perfusion injury. Prompt and early treatment can reduce mortality, despite limited resources of the hospital in high risk patients with history of triple vessel disease. Case report, Male 53 years old has been diagnosed with NSTEMI with 3VD and comorbid disease of Hypertension and has undergone revascularization management with Percutaneous coronary intervention. Ventricular tachycardia leading to cardiac arrest occurred right after the stent was inserted. Resuscitation was performed for almost 2 hours until spontaneous circulation returned. Patient admitted in ICU with refractory cardiac shock despite using combination of ionotropic and vasopressor agents under standard non-invasive monitoring due to the limitation of the hospital. Angiography was performed again 5 hours later to exclude other possibilities of blockage of coronary arteries and conclude diagnosis of myocardial reperfusion injury. Patient continually managed with combination of antiplatelet agents and maintenance dose of anti-arrhythmia agents. The handling of the patient was to focus more on supportive and preventive from further deteriorating of the condition. Patient showed clinically improvement and regained consciousness within 24 hours. Patient was successfully discharged from ICU within 3 days without any neurological sequela and was discharge from hospital after 3 days observation in general ward. Limited Resource of hospital did not refrain the physician from attaining a good outcome for this myocardial reperfusion injury case and angiography alone can be used to confirm the diagnosis of myocardial reperfusion injury. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=limited%20resources%20hospital" title="limited resources hospital">limited resources hospital</a>, <a href="https://publications.waset.org/abstracts/search?q=myocardial%20reperfusion%20injury" title=" myocardial reperfusion injury"> myocardial reperfusion injury</a>, <a href="https://publications.waset.org/abstracts/search?q=prolonged%20resuscitation" title=" prolonged resuscitation"> prolonged resuscitation</a>, <a href="https://publications.waset.org/abstracts/search?q=refractory%20cardiogenic%20shock" title=" refractory cardiogenic shock"> refractory cardiogenic shock</a>, <a href="https://publications.waset.org/abstracts/search?q=reperfusion%20arrhythmia" title=" reperfusion arrhythmia"> reperfusion arrhythmia</a>, <a href="https://publications.waset.org/abstracts/search?q=revascularization" title=" revascularization"> revascularization</a>, <a href="https://publications.waset.org/abstracts/search?q=triple-vessel%20disease" title=" triple-vessel disease"> triple-vessel disease</a> </p> <a href="https://publications.waset.org/abstracts/63220/myocardial-reperfusion-injury-during-percutaneous-coronary-intervention-in-patient-with-triple-vessel-disease-in-limited-resources-hospital-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63220.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">54</span> Fallacies of Argumentation in Modern American Political Discourse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zarine%20Avetisyan">Zarine Avetisyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The process of speech production and transmission naturally implies the occurrence of certain defective assumptions and erroneous formulations which may be both spontaneous, caused by haste, carelessness, etc., or deliberate.
