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">5212</span> Influence of Pediococcus Pentasaceus Isolate “Dadih” (Buffalo Milk Fermended in Bamboo) the Bowel Frequence, Secretory Immunoglobulin a Level and Height of Ileum Villi of the Mice EPEC Induced Diarrhea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Endang%20Purwati%20Rahayuningsih">Endang Purwati Rahayuningsih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is Enteropathogenic Eschericia coli O157 (EPEC) is one of the pathogen that can cause inflamation and damage intestinal mucosa, which is leading diarrhea. Inflamation in the intestinal mucosa proved by the presence of secretory Immunoglobulin A (sIgA) on the feces. Isolate dadih is Pediococcus pentosaceus (P. pentosaceus) as a probiotic lactic acid bacteria (LAB) is very usefull to improve sIgA and intestinal mucosa. The objective, to determine the dose and duration administration of P. pentosaceus for bowel frequence, sIgA level and height of illeum villi in mice EPEC-induced diarrhea. Method, using Complete Randomized design studies in mice EPEC-induced diarrhea. Mice was classified into 2 factors. A factor (dose of probiotic) and B factor (duration of probiotic observation) consisted of 0 hour, 12 hours, 24 hours and 36 hours. A factor consisted of negative control, positive control (mice induced by EPEC) and 3 different dose experimental mice. The results were a very significant interaction between dose and duration administration of P. pentosaceus. Mean of the most frequent defecation of mice EPEC-induced was 55 graetly reduced into 12 ,after 24 hours administration P. pentosaceus dose 2 x 1010 cfu/g, Mean of sIgA level of mice induced EPEC was 1,60 μg/ml, very significant different (p<0,01). Mean of sIgA level after 24 administration P. pentosaceus dose 2 x 1010cfu/g was 2,65 μg/ml. Mean of height of illeum villi after induced EPEC 53,04 μm with very significant different after 24 hours administration P. pentosaceus dose 2 x 1010cfu/g (142,881μm). This study concluded that P. pentosaceus dose 2 x 1010cfu/g after 24 hours is very beneficial to reduced bowel frequence, increase sIgA level and improve the height illeum villi of mice EPEC-induced diarrhea. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pediococcus%20pentosaceus" title="Pediococcus pentosaceus">Pediococcus pentosaceus</a>, <a href="https://publications.waset.org/abstracts/search?q=sIgA" title=" sIgA"> sIgA</a>, <a href="https://publications.waset.org/abstracts/search?q=enteropathogenic%20Eschericia%20coli%20O157" title=" enteropathogenic Eschericia coli O157"> enteropathogenic Eschericia coli O157</a>, <a href="https://publications.waset.org/abstracts/search?q=diarrhea" title=" diarrhea"> diarrhea</a>, <a href="https://publications.waset.org/abstracts/search?q=illeum%20villi" title=" illeum villi"> illeum villi</a> </p> <a href="https://publications.waset.org/abstracts/19388/influence-of-pediococcus-pentasaceus-isolate-dadih-buffalo-milk-fermended-in-bamboo-the-bowel-frequence-secretory-immunoglobulin-a-level-and-height-of-ileum-villi-of-the-mice-epec-induced-diarrhea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19388.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">475</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">5211</span> Elevated Celiac Antibodies and Abnormal Duodenal Biopsies Associated with IBD Markers: Possible Role of Altered Gut Permeability and Inflammation in Gluten Related Disorders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manav%20Sabharwal">Manav Sabharwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruda%20Rai%20Md"> Ruda Rai Md</a>, <a href="https://publications.waset.org/abstracts/search?q=Candace%20Parker"> Candace Parker</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Ridley"> James Ridley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wheat is one of the most commonly consumed grains worldwide, which contains gluten. Nowadays, gluten intake is considered to be a trigger for GRDs, including Celiac disease (CD), a common genetic disease affecting 1% of the US population, non-celiac gluten sensitivity (NCGS) and wheat allergy. NCGS is being recognized as an acquired gluten-sensitive enteropathy that is prevalent across age, ethnic and geographic groups. The cause of this entity is not fully understood, and recent studies suggest that it is more common in participants with irritable bowel syndrome (IBS), with iron deficiency anemia, symptoms of fatigue, and has considerable overlap in symptoms with IBS and Crohn’s disease. However, these studies were lacking in availability of complete serologies, imaging tests and/or pan-endoscopy. We performed a prospective study of 745 adult patients who presented to an outpatient clinic for evaluation of chronic upper gastro-intestinal symptoms and subsequently underwent an upper endoscopic (EGD) examination as standard of care. Evaluation comprised of comprehensive celiac antibody panel, inflammatory bowel disease (IBD) serologic markers, duodenal biopsies and Small Bowel Video Capsule Endoscopy (VCE), when available. At least 6 biopsy specimens were obtained from the duodenum and proximal jejunum during EGD, and CD3+ Intraepithelial lymphocytes (IELs) and villous architecture were evaluated by a single experienced pathologist, and VCE was performed by a single experienced gastroenterologist. Of the 745 patients undergoing EGD, 12% (93/745) patients showed elevated CD3+ IELs in the duodenal biopsies. 52% (387/745) completed a comprehensive CD panel and 7.2% (28/387) were positive for at least 1 CD antibody (Tissue transglutaminase (tTG), being the most common antibody in 65% (18/28)). Of these patients, 18% (5/28) showed increased duodenal CD3+ IELs, but 0% showed villous blunting or distortion to meet criteria for CD. Surprisingly, 43% (12/28) were positive for at 1 IBD serology (ASCA, ANCA or expanded IBD panel (LabCorp)). Of these 28 patients, 29% (8/28) underwent a SB VCE, of which 100 % (8/8) showed significant jejuno-ileal mucosal lesions diagnostic for IBD. Findings of abnormal CD antibodies (7.2%, 28/387) and increased CD3+ IELs on duodenal biopsy (12%, 93/745) were observed frequently in patients with UGI symptoms undergoing EGD in an outpatient clinic. None met criteria for CD, and a high proportion (43%, 12/28) showed evidence of overlap with IBD. This suggests a potential causal link of acquired GRDs to underlying inflammation and gut mucosal barrier disruption. Further studies to investigate a role for abnormal antigen presentation of dietary gluten to gut associated lymphoid tissue as a cause are justified. This may explain a high prevalence of GRDs in the population and correlation with IBS, IBD and other gut inflammatory disorders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=celiac" title="celiac">celiac</a>, <a href="https://publications.waset.org/abstracts/search?q=gluten%20sensitive%20enteropathy" title=" gluten sensitive enteropathy"> gluten sensitive enteropathy</a>, <a href="https://publications.waset.org/abstracts/search?q=lymphocitic%20enteritis" title=" lymphocitic enteritis"> lymphocitic enteritis</a>, <a href="https://publications.waset.org/abstracts/search?q=IBS" title=" IBS"> IBS</a>, <a href="https://publications.waset.org/abstracts/search?q=IBD" title=" IBD"> IBD</a> </p> <a href="https://publications.waset.org/abstracts/147286/elevated-celiac-antibodies-and-abnormal-duodenal-biopsies-associated-with-ibd-markers-possible-role-of-altered-gut-permeability-and-inflammation-in-gluten-related-disorders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147286.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">169</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">5210</span> Risk of Fractures at Different Anatomic Sites in Patients with Irritable Bowel Syndrome: A Nationwide Population-Based Cohort Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Herng-Sheng%20Lee">Herng-Sheng Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi-Yi%20Chen"> Chi-Yi Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Wan-Ting%20Huang"> Wan-Ting Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Li-Jen%20Chang"> Li-Jen Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Solomon%20Chih-Cheng%20Chen"> Solomon Chih-Cheng Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsin-Yi%20Yang"> Hsin-Yi Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A variety of gastrointestinal disorders, such as Crohn’s disease, ulcerative colitis, and coeliac disease, are recognized as risk factors for osteoporosis and osteoporotic fractures. One recent study suggests that individuals with irritable bowel syndrome (IBS) might also be at increased risk of osteoporosis and osteoporotic fractures. Up to now, the association between IBS and the risk of fractures at different anatomic sites occurrences is not completely clear. We conducted a population-based cohort analysis to investigate the fracture risk of IBS in comparison with non-IBS group. We identified 29,505 adults aged ≥ 20 years with newly diagnosed IBS using the Taiwan National Health Insurance Research Database in 2000-2012. A comparison group was constructed of patients without IBS who were matched according to gender and age. The occurrence of fracture was monitored until the end of 2013. We analyzed the risk of fracture events to occur in IBS by using Cox proportional hazards regression models. Patients with IBS had a higher incidence of osteoporotic fractures compared with non-IBS group (12.34 versus 9.45 per 1,000 person-years) and an increased risk of osteoporotic fractures (adjusted hazard ratio [aHR] = 1.27, 95 % confidence interval [CI] = 1.20 – 1.35). Site specific analysis showed that the IBS group had a higher risk of fractures for spine, forearm, hip and hand than did the non-IBS group. With further stratification for gender and age, a higher aHR value for osteoporotic fractures in IBS group was seen across all age groups in males, but seen in elderly females. In addition, female, elderly, low income, hypertension, coronary artery disease, cerebrovascular disease, and depressive disorders as independent osteoporotic fracture risk factors in IBS patients. The IBS is considered as a risk factor for osteoporotic fractures, particularly in female individuals and fracture sites located at the spine, forearm, hip and hand. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=irritable%20bowel%20syndrome" title="irritable bowel syndrome">irritable bowel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20difference" title=" gender difference"> gender difference</a>, <a href="https://publications.waset.org/abstracts/search?q=longitudinal%20health%20insurance%20database" title=" longitudinal health insurance database"> longitudinal health insurance database</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20health" title=" public health"> public health</a> </p> <a href="https://publications.waset.org/abstracts/96479/risk-of-fractures-at-different-anatomic-sites-in-patients-with-irritable-bowel-syndrome-a-nationwide-population-based-cohort-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96479.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">5209</span> Analysis and Prediction of COVID-19 by Using Recurrent LSTM Neural Network Model in Machine Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Grienggrai%20Rajchakit">Grienggrai Rajchakit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As we all know that coronavirus is announced as a pandemic in the world by WHO. It is speeded all over the world with few days of time. To control this spreading, every citizen maintains social distance and self-preventive measures are the best strategies. As of now, many researchers and scientists are continuing their research in finding out the exact vaccine. The machine learning model finds that the coronavirus disease behaves in an exponential manner. To abolish the consequence of this pandemic, an efficient step should be taken to analyze this disease. In this paper, a recurrent neural network model is chosen to predict the number of active cases in a particular state. To make this prediction of active cases, we need a database. The database of COVID-19 is downloaded from the KAGGLE website and is analyzed by applying a recurrent LSTM neural network with univariant features to predict the number of active cases of patients suffering from the corona virus. The downloaded database is divided into training and testing the chosen neural network model. The model is trained with the training data set and tested with a testing dataset to predict the number of active cases in a particular state; here, we have concentrated on Andhra Pradesh state. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=coronavirus" title=" coronavirus"> coronavirus</a>, <a href="https://publications.waset.org/abstracts/search?q=KAGGLE" title=" KAGGLE"> KAGGLE</a>, <a href="https://publications.waset.org/abstracts/search?q=LSTM%20neural%20network" title=" LSTM neural network"> LSTM neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/143094/analysis-and-prediction-of-covid-19-by-using-recurrent-lstm-neural-network-model-in-machine-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143094.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">160</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">5208</span> The Contribution of Hip Strategy in Dynamic Balance in Recurrent Ankle Sprain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radwa%20Talaat%20Mohammed%20El-Shorbagy">Radwa Talaat Mohammed El-Shorbagy</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20El-Din%20Balbaa"> Alaa El-Din Balbaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Ayad"> Khaled Ayad</a>, <a href="https://publications.waset.org/abstracts/search?q=Waleed%20Red"> Waleed Red</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Ankle sprain is a common lower limb injury that is complicated by high recurrence rate. The cause of recurrence is not clear; however, changes in motor control have been postulated. Objective: To determine the contribution of proximal hip strategy to dynamic balance control in patients with recurrent ankle sprain. Methods: Fifteen subjects with recurrent ankle sprain (group A) and fifteen healthy control subjects (group B) participated in this study. Abductor-adductors as well as flexor-extensor hip musculatures control was abolished by fatigue using the Biodex Isokinetic system. Dynamic balance was measured before and after fatigue by the Biodex Balance system Results: Repeated measures MANOVA was used to compare between and within group differences. In group A fatiguing of hip muscles (flexors-extensors and abductors-adductors) increased overall stability index (OASI), anteroposterior stability index (APSI) and mediolateral stability index (MLSI) significantly (p=0.00) whereas; in group B fatiguing of hip flexors-extensors increased significantly OASI and APSI only (p= 0.017, 0.010; respectively) while fatiguing of hip abductors-adductors has no significant effect on these variables. Moreover, patients with ankle sprain had significantly lower dynamic balance after hip muscles fatigue compared to the control group. Specifically, after hip flexor-extensor fatigue, the OASI, APSI and MLSI were increased significantly than those of the control values (p=0.002, 0.011, and 0.003, respectively) whereas fatiguing of hip abductors-adductors increased significantly in OASI and APSI only (p=0.012, 0.026, respectively). Conclusion: To maintain dynamic balance, patients with recurrent ankle sprain seem to relay more on the hip strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ankle%20sprain" title="ankle sprain">ankle sprain</a>, <a href="https://publications.waset.org/abstracts/search?q=hip%20muscles%20fatigue" title=" hip muscles fatigue"> hip muscles fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20balance" title=" dynamic balance"> dynamic balance</a> </p> <a href="https://publications.waset.org/abstracts/23132/the-contribution-of-hip-strategy-in-dynamic-balance-in-recurrent-ankle-sprain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23132.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">491</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">5207</span> Analysis of Post-vaccination Immunity in Children with Severe Chronic Diseases Receiving Immunosuppressive Therapy by Specific IgG Antibodies Definition Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marina%20G.%20Galitskaya">Marina G.

Therefore, preventive vaccination is especially important for these children. However, due to the immunosuppressive effects of treatment for the underlying disease, the effectiveness of vaccination may decrease below the protective level. In a multidisciplinary children's medical center, post-vaccination immunity was studied in 79 children aged 4-17 years. The children were divided into 2 groups: Group 1 (38 children) with kidney pathology (Nephrotic Syndrome) and Group 2 (41 children) with inflammatory bowel diseases (Ulcerative Colitis, Crohn's Disease). Both groups of children were vaccinated according to the national vaccination calendar and received immunosuppressive therapy (prednisolone, methotrexate, cyclosporine, and other drugs) for at least 1 year. Using the enzyme-linked immunosorbent assay method, specific IgG antibodies to vaccine-preventable infections were determined: measles, rubella, mumps, diphtheria, pertussis, tetanus, and hepatitis B. The study showed the percentage of children with positive IgG values for vaccine-preventable infections. The highest percentage of children had protective antibody levels to measles (84.2% in children with nephrotic syndrome and 92.6% in those with inflammatory bowel disease) and rubella (71% and 80.4%, respectively). The lowest percentage of children with protective antibodies was for hepatitis B (5.2% and 29.2% respectively). Antibodies to mumps, diphtheria, pertussis, and tetanus were found not in all children (from 39,4% to 82,9%). The remaining percentage of children did not have detectable IgG antibodies to vaccine-preventable infections. Not all children, despite the previous vaccination, preserved antibodies to vaccine-controlled infections and remained unprotected by specific IgG antibodies. The issue of a booster vaccine dose should be considered in children without contraindications to vaccination. Children receiving long-term immunosuppressive therapy require an individual vaccination approach, including a specific definition of the performed vaccination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=immunosuppressive%20therapy" title="immunosuppressive therapy">immunosuppressive therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20bowel%20diseases" title=" inflammatory bowel diseases"> inflammatory bowel diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=nephrotic%20syndrome" title=" nephrotic syndrome"> nephrotic syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=post-vaccination%20immunity" title=" post-vaccination immunity"> post-vaccination immunity</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20antibodies" title=" specific antibodies"> specific antibodies</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccine-preventable%20infections." title=" vaccine-preventable infections."> vaccine-preventable infections.</a> </p> <a href="https://publications.waset.org/abstracts/186797/analysis-of-post-vaccination-immunity-in-children-with-severe-chronic-diseases-receiving-immunosuppressive-therapy-by-specific-igg-antibodies-definition-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186797.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">33</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">5206</span> Recurrent Neural Networks for Complex Survival Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pius%20Marthin">Pius Marthin</a>, <a href="https://publications.waset.org/abstracts/search?q=Nihal%20Ata%20Tutkun"> Nihal Ata Tutkun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Survival analysis has become one of the paramount procedures in the modeling of time-to-event data. When we encounter complex survival problems, the traditional approach remains limited in accounting for the complex correlational structure between the covariates and the outcome due to the strong assumptions that limit the inference and prediction ability of the resulting models. Several studies exist on the deep learning approach to survival modeling; moreover, the application for the case of complex survival problems still needs to be improved. In addition, the existing models need to address the data structure's complexity fully and are subject to noise and redundant information. In this study, we design a deep learning technique (CmpXRnnSurv_AE) that obliterates the limitations imposed by traditional approaches and addresses the above issues to jointly predict the risk-specific probabilities and survival function for recurrent events with competing risks. We introduce the component termed Risks Information Weights (RIW) as an attention mechanism to compute the weighted cumulative incidence function (WCIF) and an external auto-encoder (ExternalAE) as a feature selector to extract complex characteristics among the set of covariates responsible for the cause-specific events. We train our model using synthetic and real data sets and employ the appropriate metrics for complex survival models for evaluation. As benchmarks, we selected both traditional and machine learning models and our model demonstrates better performance across all datasets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cumulative%20incidence%20function%20%28CIF%29" title="cumulative incidence function (CIF)">cumulative incidence function (CIF)</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20information%20weight%20%28RIW%29" title=" risk information weight (RIW)"> risk information weight (RIW)</a>, <a href="https://publications.waset.org/abstracts/search?q=autoencoders%20%28AE%29" title=" autoencoders (AE)"> autoencoders (AE)</a>, <a href="https://publications.waset.org/abstracts/search?q=survival%20analysis" title=" survival analysis"> survival analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrent%20events%20with%20competing%20risks" title=" recurrent events with competing risks"> recurrent events with competing risks</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrent%20neural%20networks%20%28RNN%29" title=" recurrent neural networks (RNN)"> recurrent neural networks (RNN)</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20short-term%20memory%20%28LSTM%29" title=" long short-term memory (LSTM)"> long short-term memory (LSTM)</a>, <a href="https://publications.waset.org/abstracts/search?q=self-attention" title=" self-attention"> self-attention</a>, <a href="https://publications.waset.org/abstracts/search?q=multilayers%20perceptrons%20%28MLPs%29" title=" multilayers perceptrons (MLPs)"> multilayers perceptrons (MLPs)</a> </p> <a href="https://publications.waset.org/abstracts/163993/recurrent-neural-networks-for-complex-survival-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163993.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">89</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">5205</span> Management of First Trimester Miscarriage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madeleine%20Cox">Madeleine Cox</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective; analyse patient choices in management of first trimester miscarriage, rates of complications including repeat procedure. Design: all first trimester miscarriages from a tertiary institution on the Gold Coast in a 6 month time frame (July to December 2021) were reviewed, including choice of management, histopathology, any representations or admissions, and potential complications. Results: a total of 224 first trimester miscarriages were identified. Of these, 183 (81%) opted to have surgical management in the first instance. Of the remaining patients, 18 (8%) opted to have medical management, and 28 (12.5%) opted to have expectant management. In total, 33(15%) patients required a repeat treatment for retained products. 1 had medical management for a small volume PROC post suction curette. A significant number of these patients initially opted for medical management but then elected to have shorter follow up than usual and went on to have retained products noted. 5 women who had small volumes of RPOC post medical or surgical management had repeat suction curette, however, had very small volumes of products on scan and on curette and may have had a good result with repeated misoprostol administration. It is important to note that whilst a common procedure, suction curettes are not without risk. 2 women had significant blood loss of 1L and 1.5L. A third women had a uterine perforation, a rare but recognised complication, she went on to require a laparoscopy which identified a small serosal bowel injury which was closed by the colorectal team. Conclusion: Management of first trimester miscarriage should be guided by patient preference. It is important to be able to provide patients with their choice of management, however, it is also important to have a good understanding of the risks of each management choice, chances of repeated procedure, appropriate time frame for follow up. Women who choose to undertake medical or expectant management should be supported through this time, with appropriate time frame between taking misoprostol and repeat scan so that the true effects can be evaluated. Patients returning for scans within 2-3 days are more likely to be booked for further surgery, however, may reflect patients who did not have adequate counselling or simply changed their mind on their preferred management options. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=miscarriage" title="miscarriage">miscarriage</a>, <a href="https://publications.waset.org/abstracts/search?q=gynaecology" title=" gynaecology"> gynaecology</a>, <a href="https://publications.waset.org/abstracts/search?q=obstetrics" title=" obstetrics"> obstetrics</a>, <a href="https://publications.waset.org/abstracts/search?q=first%20trimester" title=" first trimester"> first trimester</a> </p> <a href="https://publications.waset.org/abstracts/148754/management-of-first-trimester-miscarriage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148754.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">101</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">5204</span> Vision-Based Collision Avoidance for Unmanned Aerial Vehicles by Recurrent Neural Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yao-Hong%20Tsai">Yao-Hong Tsai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the sensor technology, video surveillance has become the main way for security control in every big city in the world. Surveillance is usually used by governments for intelligence gathering, the prevention of crime, the protection of a process, person, group or object, or the investigation of crime. Many surveillance systems based on computer vision technology have been developed in recent years. Moving target tracking is the most common task for Unmanned Aerial Vehicle (UAV) to find and track objects of interest in mobile aerial surveillance for civilian applications. The paper is focused on vision-based collision avoidance for UAVs by recurrent neural networks. First, images from cameras on UAV were fused based on deep convolutional neural network. Then, a recurrent neural network was constructed to obtain high-level image features for object tracking and extracting low-level image features for noise reducing. The system distributed the calculation of the whole system to local and cloud platform to efficiently perform object detection, tracking and collision avoidance based on multiple UAVs. The experiments on several challenging datasets showed that the proposed algorithm outperforms the state-of-the-art methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unmanned%20aerial%20vehicle" title="unmanned aerial vehicle">unmanned aerial vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20tracking" title=" object tracking"> object tracking</a>, <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=collision%20avoidance" title=" collision avoidance"> collision avoidance</a> </p> <a href="https://publications.waset.org/abstracts/99181/vision-based-collision-avoidance-for-unmanned-aerial-vehicles-by-recurrent-neural-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99181.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">160</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">5203</span> Protein Tertiary Structure Prediction by a Multiobjective Optimization and Neural Network Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20Barbosa%20de%20Almeida">Alexandre Barbosa de Almeida</a>, <a href="https://publications.waset.org/abstracts/search?q=Telma%20Woerle%20de%20Lima%20Soares"> Telma Woerle de Lima Soares</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Protein structure prediction is a challenging task in the bioinformatics field.

Also, to introduce a planning method in our department to treat prostate cancer by utilizing high energy photons without increasing patient toxicity and fulfilled all dosimetric constraints for OAR (an organ at risk). Then toevaluate the target 95% coverage PTV95, V5%, V2%, V1%, low dose volume for OAR (V1Gy, V2Gy, V5Gy), monitor unit (beam-on time), and estimate the values of homogeneity index HI, conformity index CI a Gradient index GI for each treatment plan.Materials/Methods: Two treatment plans were generated for15 patients with localized prostate cancer retrospectively using the CT planning image acquired for radiotherapy purposes. Each plan contains two/three complete arcs with two/three different collimator angle sets. The maximum dose rate available is 1400MU/min for the energy 6FFF and 2400MU/min for 10FFF. So in case, we need to avoid changing the gantry speed during the rotation, we tend to use the third arc in the plan with 6FFF to accommodate the high dose per fraction. The clinical target volume (CTV) consists of the entire prostate for organ-confined disease. The planning target volume (PTV) involves a margin of 5 mm. A 3-mm margin is favored posteriorly. Organs at risk identified and contoured include the rectum, bladder, penile bulb, femoral heads, and small bowel. The prescription dose is to deliver 35Gyin five fractions to the PTV and apply constraints for organ at risk (OAR) derived from those reported in references. Results: In terms of CI=0.99, HI=0.7, and GI= 4.1, it was observed that they are all thesame for both energies 6FFF and 10FFF with no differences, but the total delivered MUs are much less for the 10FFF plans (2907 for 6FFF vs.2468 for 10FFF) and the total delivery time is 124Sc for 6FFF vs. 61Sc for 10FFF beams. There were no dosimetric differences between 6FFF and 10FFF in terms of PTV coverage and mean doses; the mean doses for the bladder, rectum, femoral heads, penile bulb, and small bowel were collected, and they were in favor of the 10FFF. Also, we got lower V1Gy, V2Gy, and V5Gy doses for all OAR with 10FFF plans. Integral dosesID in (Gy. L) were recorded for all OAR, and they were lower with the 10FFF plans. Conclusion: High energy 10FFF has lower treatment time and lower delivered MUs; also, 10FFF showed lower integral and meant doses to organs at risk. In this study, we suggest usinga 10FFF beam for SBRTprostate treatment, which has the advantage of lowering the treatment time and that lead to lessplan complexity with respect to 6FFF beams. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FFF%20beam" title="FFF beam">FFF beam</a>, <a href="https://publications.waset.org/abstracts/search?q=SBRT%20prostate" title=" SBRT prostate"> SBRT prostate</a>, <a href="https://publications.waset.org/abstracts/search?q=VMAT" title=" VMAT"> VMAT</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20cancer" title=" prostate cancer"> prostate cancer</a> </p> <a href="https://publications.waset.org/abstracts/151095/the-impact-of-using-flattening-filter-free-energies-on-treatment-efficiency-for-prostate-sbrt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151095.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">5200</span> Pterygium Recurrence Rate and Influencing Factors for Recurrence of Pterygium after Pterygium Surgery at an Eastern Thai University Hospital</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luksanaporn%20Krungkraipetch">Luksanaporn Krungkraipetch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pterygium is a frequent ocular surface lesion that begins in the limbal conjunctiva within the palpebral fissure and spreads to the cornea. The lesion is more common in the nasal limbus than in the temporal, and it has a wing-like aspect. Indications for surgery, in decreasing order of significance, are growth over the corneal center, decreased vision due to corneal deformation, documented growth, sensations of discomfort, and esthetic concerns. The aim of this study is twofold: first, to determine the frequency of pterygium recurrence after surgery at the mentioned hospital, and second, to identify the factors that influence the recurrence of pterygium. The research design is a retrospective examination of 164 patient samples in an eastern Thai university hospital (Code 13766). Data analysis is descriptive statistics analysis, i.e., basic data details about pterygium surgery and the risk of recurrent pterygium, and for factor analysis, the inferential statistics chi-square and ANOVA are utilized. Twenty-four of the 164 patients who underwent surgery exhibited recurrent pterygium. Consequently, the incidence of recurrent pterygium after surgery was 14.6%. There were an equal number of men and women present. The participants' ages ranged from 41 to 60 years (62, 8 percent). According to the findings, the majority of patients were female (60.4%), over the age of 60 (51.2%), did not live near the beach (83.5%), did not have an underlying disease (92.1%), and 95.7% did not have any other eye problems. Gender (X² = 1.26, p = .289), age (X² = 5.86, p = .119), an address near the sea (X² = 3.30, p = .081)), underlying disease (X² = 0.54, p = .694), and eye disease (X² = 0.00, p = 1.00) had no effect on pterygium recurrence. Recurrences occurred in 79.1% of all surgical procedures and 11.6% of all patients using the bare sclera technique. The recurrence rate for conjunctival autografts was 20.9% for all procedures and 3.0% for all participants. Mitomycin-C and amniotic membrane transplant techniques had no recurrence following surgery. Comparing the surgeries done on people with recurrent pterygium did not show anything important (F = 1.13, p = 0.339). In conclusion, the prevalence of pterygium recurrence following pterygium, 14.6%, does not differ from earlier research. Underlying disease, other eye conditions, and surgical procedures such as pterygium recurrence are unaffected by pterygium surgery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pterygium" title="pterygium">pterygium</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrence%20pterygium" title=" recurrence pterygium"> recurrence pterygium</a>, <a href="https://publications.waset.org/abstracts/search?q=pterygium%20surgery" title=" pterygium surgery"> pterygium surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=excision%20pterygium" title=" excision pterygium"> excision pterygium</a> </p> <a href="https://publications.waset.org/abstracts/172966/pterygium-recurrence-rate-and-influencing-factors-for-recurrence-of-pterygium-after-pterygium-surgery-at-an-eastern-thai-university-hospital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172966.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">70</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">5199</span> A 30 Year Audit of the Vascular Complications of Ports: Permanent Intravascular Access Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Kershaw">S.

With time, peripheral venous access can become difficult and limited. Accessing these veins can become arduous, traumatic, painful and unworkable. A permanent intravascular access device or Port is a small device that is inserted into the central venous system that allows the delivery of medicine eliminating the need for peripheral venous access. Ports represent a convenient and efficient method when venous access is required on a permanent basis however they are also associated with significant vascular complications. Superior Vena Cava Obstruction (SVCO) is a rare but significant vascular complication of ports in this setting. Objective: We aimed to look at a single CF centre’s experience of port-related SVCO over a thirty year period. Methods: Retrospective data was extracted using patient’s notes, electronic radiological reports and local databases over a period in excess of 30 years from 1982 to 2014. Results: 13 patients were identified with SVCO as a result of their port. 11 patients had CF (9 female, 2 male), one male patient had Primary Ciliary Dyskinesia and one female patient had severe Asthma. The mean port function was 1532 days (range 110 – 4049) and the mean age at SVCO was 24 years (range 11.1 to 36.5 years). The most common symptoms were facial oedema (n=8, 61.5%) and dilated veins (n=6, 46.2%). 7 patients had their Ports removed after SVCO. 6 patients underwent attempted stenting (46.2%) and 6 did not. 4 out of the 6 who underwent stenting required/had re-intervention. 3 of the 6 patients who underwent stenting had symptom resolution, however, 4 of the 6 patients who were not stented had symptom resolution also. Symptom resolution was not guaranteed with stenting and required re-intervention in two-thirds. Conclusion: This case series represents the experience of one of the longest established CF units in the UK and represents the largest cohort ever reported in the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ports" title="ports">ports</a>, <a href="https://publications.waset.org/abstracts/search?q=Superior%20Vena%20Cava%20Obstruction" title=" Superior Vena Cava Obstruction"> Superior Vena Cava Obstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=cystic%20fibrosis" title=" cystic fibrosis"> cystic fibrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=access%20devices" title=" access devices "> access devices </a> </p> <a href="https://publications.waset.org/abstracts/16886/a-30-year-audit-of-the-vascular-complications-of-ports-permanent-intravascular-access-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16886.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">322</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">5198</span> Association between a Serotonin Re-Uptake Transporter Gene Polymorphism and Mucosal Serotonin Level in Women Patients with Irritable Bowel Syndrome and Healthy Control: A Pilot Study from Northern India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kumar">Sunil Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Uday%20C.%20Ghoshal"> Uday C. Ghoshal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and aims: Serotonin (5-hydroxtryptamine, 5-HT) is an important factor in gut function, playing key roles in intestinal peristalsis and secretion, and in sensory signaling in the brain-gut axis. Removal from its sites of action is mediated by a specific protein called the serotonin reuptake transporter (SERT). Polymorphisms in the promoter region of the SERT gene have effects on transcriptional activity, resulting in altered 5-HT reuptake efficiency. Functional polymorphisms may underlie disturbance in gut function in individuals suffering with disorders such as irritable bowel syndrome (IBS). The aim of this study was to assess the potential association between SERT polymorphisms and the diarrhea predominant IBS (D-IBS) phenotype Subjects: A total of 36 northern Indian female patients and 55 female northern Indian healthy controls (HC) were subjected to genotyping. Methods: Leucocyte DNA of all subjects was analyzed by polymerase chain reaction based technologies for SERT polymorphisms, specifically the insertion/deletion polymorphism in the promoter (SERT-P). Statistical analysis was performed to assess association of SERT polymorphism allele with the D-IBS phenotype. Results: The frequency of distribution of SERT-P gene was comparable between female patients with IBS and HC (p = 0.086). However, frequency of SERT-P deletion/deletion genotype was significantly higher in female patients with D-IBS compared to C-IBS and A-IBS [17/19 (89.5%) vs. 4/12 (33.3%) vs. 1/5 (20%), p=0.001, respectively]. The mucosal level of serotonin was higher in D-IBS compared to C-IBS and A-IBS [Median, range (159.26, 98.78–212.1) vs. 110.4, 67.87–143.53 vs. 92.34, 78.8–166.3 pmol/mL, p=0.001, respectively]. The mucosal level of serotonin was higher in female patients with IBS with SERT-P deletion/deletion genotype compared deletion/insertion and insertion/insertion [157.65, 67.87–212.1 vs. 110.4, 78.1–143.32 vs. 100.5, 69.1–132.03 pmol/mL, p=0.001, respectively]. Patients with D-IBS with deletion/deletion genotype more often reported symptoms of abdominal pain, discomfort (p=0.025) and bloating (p=0.039). Symptoms development following lactose ingestion was strongly associated with D-IBS and SERT-P deletion/deletion genotype (p=0.004). Conclusions: Significant association was observed between D-IBS and the SERT-P deletion/deletion genotype, suggesting that the serotonin transporter is a potential candidate gene for D-IBS in women. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=serotonin" title="serotonin">serotonin</a>, <a href="https://publications.waset.org/abstracts/search?q=SERT" title=" SERT"> SERT</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20bowel%20disease" title=" inflammatory bowel disease"> inflammatory bowel disease</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20polymorphism" title=" genetic polymorphism"> genetic polymorphism</a> </p> <a href="https://publications.waset.org/abstracts/21586/association-between-a-serotonin-re-uptake-transporter-gene-polymorphism-and-mucosal-serotonin-level-in-women-patients-with-irritable-bowel-syndrome-and-healthy-control-a-pilot-study-from-northern-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21586.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">333</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">5197</span> Using Wearable Device with Neuron Network to Classify Severity of Sleep Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ru-Yin%20Yang">Ru-Yin Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi%20Wu"> Chi Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng-Yu%20Tsai"> Cheng-Yu Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Yin-Tzu%20Lin"> Yin-Tzu Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Te%20Liu"> Wen-Te Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Sleep breathing disorder (SDB) is a condition demonstrated by recurrent episodes of the airway obstruction leading to intermittent hypoxia and quality fragmentation during sleep time. However, the procedures for SDB severity examination remain complicated and costly. Objective: The objective of this study is to establish a simplified examination method for SDB by the respiratory impendence pattern sensor combining the signal processing and machine learning model. Methodologies: We records heart rate variability by the electrocardiogram and respiratory pattern by impendence. After the polysomnography (PSG) been done with the diagnosis of SDB by the apnea and hypopnea index (AHI), we calculate the episodes with the absence of flow and arousal index (AI) from device record. Subjects were divided into training and testing groups. Neuron network was used to establish a prediction model to classify the severity of the SDB by the AI, episodes, and body profiles. The performance was evaluated by classification in the testing group compared with PSG. Results: In this study, we enrolled 66 subjects (Male/Female: 37/29; Age:49.9±13.2) with the diagnosis of SDB in a sleep center in Taipei city, Taiwan, from 2015 to 2016. The accuracy from the confusion matrix on the test group by NN is 71.94 %. Conclusion: Based on the models, we established a prediction model for SDB by means of the wearable sensor. With more cases incoming and training, this system may be used to rapidly and automatically screen the risk of SDB in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sleep%20breathing%20disorder" title="sleep breathing disorder">sleep breathing disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=apnea%20and%20hypopnea%20index" title=" apnea and hypopnea index"> apnea and hypopnea index</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20parameters" title=" body parameters"> body parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=neuron%20network" title=" neuron network"> neuron network</a> </p> <a href="https://publications.waset.org/abstracts/98071/using-wearable-device-with-neuron-network-to-classify-severity-of-sleep-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98071.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">5196</span> A Case Report: The Role of Gut Directed Hypnotherapy in Resolution of Irritable Bowel Syndrome in a Medication Refractory Pediatric Male Patient</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alok%20Bapatla">Alok Bapatla</a>, <a href="https://publications.waset.org/abstracts/search?q=Pamela%20Lutting"> Pamela Lutting</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariastella%20Serrano"> Mariastella Serrano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder characterized by abdominal pain associated with altered bowel habits in the absence of an underlying organic cause. Although the exact etiology of IBS is not fully understood, one of the leading theories postulates a pathology within the Brain-Gut Axis that leads to an overall increase in gastrointestinal sensitivity and pejorative changes in gastrointestinal motility. Research and clinical practice have shown that Gut Directed Hypnotherapy (GDH) has a beneficial clinical role in improving Mind-Gut control and thereby comorbid conditions such as anxiety, abdominal pain, constipation, and diarrhea. Aims: This study presents a 17-year old male with underlying anxiety and a one-year history of IBS-Constipation Predominant Subtype (IBS-C), who has demonstrated impressive improvement of symptoms following GDH treatment following refractory trials with medications including bisacodyl, senna, docusate, magnesium citrate, lubiprostone, linaclotide. Method: The patient was referred to a licensed clinical psychologist specializing in clinical hypnosis and cognitive-behavioral therapy (CBT), who implemented “The Standardized Hypnosis Protocol for IBS” developed by Dr. Olafur S. Palsson, Psy.D at the University of North Carolina at Chapel Hill. The hypnotherapy protocol consisted of a total of seven weekly 45-minute sessions supplemented with a 20-minute audio recording to be listened to once daily. Outcome variables included the GAD-7, PHQ-9 and DCI-2, as well as self-ratings (ranging 0-10) for pain (intensity and frequency), emotional distress about IBS symptoms, and overall emotional distress. All variables were measured at intake prior to administration of the hypnosis protocol and at the conclusion of the hypnosis treatment. A retrospective IBS Questionnaire (IBS Severity Scoring System) was also completed at the conclusion of the GDH treatment for pre-and post-test ratings of clinical symptoms. Results: The patient showed improvement in all outcome variables and self-ratings, including abdominal pain intensity, frequency of abdominal pain episodes, emotional distress relating to gut issues, depression, and anxiety. The IBS Questionnaire showed a significant improvement from a severity score of 400 (defined as severe) prior to GDH intervention compared to 55 (defined as complete resolution) at four months after the last session. IBS Questionnaire subset questions that showed a significant score improvement included abdominal pain intensity, days of pain experienced per 10 days, satisfaction with bowel habits, and overall interference of life affected by IBS symptoms. Conclusion: This case supports the existing research literature that GDH has a significantly beneficial role in improving symptoms in patients with IBS. Emphasis is placed on the numerical results of the IBS Questionnaire scoring, which reflects a patient who initially suffered from severe IBS with failed response to multiple medications, who subsequently showed full and sustained resolution <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pediatrics" title="pediatrics">pediatrics</a>, <a href="https://publications.waset.org/abstracts/search?q=constipation" title=" constipation"> constipation</a>, <a href="https://publications.waset.org/abstracts/search?q=irritable%20bowel%20syndrome" title=" irritable bowel syndrome"> irritable bowel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=hypnotherapy" title=" hypnotherapy"> hypnotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=gut-directed%20hypnosis" title=" gut-directed hypnosis"> gut-directed hypnosis</a> </p> <a href="https://publications.waset.org/abstracts/130491/a-case-report-the-role-of-gut-directed-hypnotherapy-in-resolution-of-irritable-bowel-syndrome-in-a-medication-refractory-pediatric-male-patient" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130491.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">198</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">5195</span> Outcome of Anastomosis of Mechanically Prepared vs Mechanically Unprepared Bowel in Laparoscopic Anterior Resection in Surgical Units of Teaching Hospital Karapitiya ,Sri Lanka</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20P.%20v.%20R.%20de%20Silva">K.

This study was conducted to examine the clinical consequences of anastomosis in colorectal surgery with MBP compared to cases where MBP was not utilized (no-MBP) in the context of LAR. Methods: This was a retrospective comparative study conducted in the professorial surgical wards of the teaching hospital karapitiya (THK). Colorectal cancer patients(n=306) participated in the study, including 151 MBP patients and 155 no-MBP patients, where the postoperative complications and mortality rates were compared. Results: The anastomotic leakage rate was 2.6%(n=4) in the no-MBP group and 6.0%(n=9) in the MBP group (p=0.143). The postoperative paralytic ileus rate was 18.5%(n=28) and 5.8%(n=9) in the MBP group and no-MBP group, respectively, displaying a statistically significant difference (p=0.001). Wound infection, pneumonia, urinary tract infection, and cardiac complication rates also were higher in the MBP group. The overall mortality rate was 1.3%(n=3) in the no-MBP group and 2.0%(n=2) in the MBP group. Conclusions: The evidence concludes that MBP increases post-operative complications. Therefore, prophylactic MBP in LAR has not been proven to benefit patients. However, further research is necessary to understand the comparative effects of MBP versus no preparation comprehensively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MBP" title="MBP">MBP</a>, <a href="https://publications.waset.org/abstracts/search?q=anastomosis" title=" anastomosis"> anastomosis</a>, <a href="https://publications.waset.org/abstracts/search?q=LAR" title=" LAR"> LAR</a>, <a href="https://publications.waset.org/abstracts/search?q=paralytic%20ileus" title=" paralytic ileus"> paralytic ileus</a> </p> <a href="https://publications.waset.org/abstracts/171864/outcome-of-anastomosis-of-mechanically-prepared-vs-mechanically-unprepared-bowel-in-laparoscopic-anterior-resection-in-surgical-units-of-teaching-hospital-karapitiya-sri-lanka" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171864.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">92</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">5194</span> Laryngeal Tuberculosis in a 7-Year-Old Child: A Case Report and Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Jaish%20Siddiqui">Mohd Jaish Siddiqui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Laryngeal TB is extremely rare in the pediatric population, accounting for 1% of all cases.

One group had a recurrent major depressive disorder with melancholic features; the second group met the criteria for borderline personality disorder, and the third consisted of healthy controls. The Structured Clinical Interview for AXIS I DSM-IV Disorders sand the Structured Clinical Interview for AXIS II DSM-IV Disorders were used for diagnosis. The Israel Psychiatric Epidemiology Research Interview (IPERI) Life Event Scale and the Coddington Life Events Schedule (CLES) were used to measure life events which were confirmed with a confirmatory semi-structured interview. The Beck Depression Inventory and the Satisfaction from Life scales were also administered. Results : The total number of loss-related events in childhood and in the year preceding the first episode was significantly higher in the affective disorder group than in the two control groups. Total number of LE, uncontrolled and independent events were also more common in the depressed patients in the year preceding the first episode. No category of SLE was differentiated among any of the three groups during any period of time following the first depressive episode. Conclusions: SLE play an important role in the onset of affective disorders. There appear to be specific kinds of SLE occurring in childhood and in the year preceding a first episode that have particular significance. SLE may have a lesser role in the maintenance of this illness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modd%20dosorders" title="modd dosorders">modd dosorders</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrent%20depression" title=" recurrent depression"> recurrent depression</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20events" title=" life events"> life events</a> </p> <a href="https://publications.waset.org/abstracts/159177/stressful-events-and-serious-mood-disorders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159177.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">108</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">5192</span> Hard Water Softening by Chronoamperometry and Impedancemetry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Ghizellaoui">Samira Ghizellaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Manel%20Boumagoura"> Manel Boumagoura</a>, <a href="https://publications.waset.org/abstracts/search?q=Rayane%20Menzri"> Rayane Menzri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ground water Hamma rich in calcium and bicarbonate likely to deposit the tartar and subsequently lead to the obstruction of the pipes and the seizing of the stopping devices in addition to the financial losses resulting there from.

These unpredictable circumstances manifest as pipe failures, intermittent supply and burst events thus adding to water loss, energy waste and increased carbon emissions. Whilst these events are unavoidable, advanced pressure management has proved an effective tool to control and mitigate them. Henceforth, water utilities have struggled with developing a real-time control method that is resilient when confronting the challenges of water distribution. In this paper we use deep reinforcement learning (DRL) algorithms as a novel pressure control strategy to minimise pressure violations and leakage under both burst and background leakage conditions. Agents based on asynchronous actor critic (A2C) and recurrent proximal policy optimisation (Recurrent PPO) were trained and compared to benchmarked optimisation algorithms (differential evolution, particle swarm optimisation. A2C manages to minimise leakage by 32.48% under burst conditions and 67.17% under background conditions which was the highest performance in the DRL algorithms. A2C and Recurrent PPO performed well in comparison to the benchmarks with higher processing speed and lower computational effort. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20reinforcement%20learning" title="deep reinforcement learning">deep reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20management" title=" pressure management"> pressure management</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20distribution%20networks" title=" water distribution networks"> water distribution networks</a>, <a href="https://publications.waset.org/abstracts/search?q=leakage%20management" title=" leakage management"> leakage management</a> </p> <a href="https://publications.waset.org/abstracts/176527/deep-reinforcement-learning-for-advanced-pressure-management-in-water-distribution-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176527.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">5190</span> The MTHFR C677T Polymorphism Screening: A Challenge in Recurrent Pregnancy Loss</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rim%20Frikha">Rim Frikha</a>, <a href="https://publications.waset.org/abstracts/search?q=Nouha%20Bouayed"> Nouha Bouayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Afifa%20Sellami"> Afifa Sellami</a>, <a href="https://publications.waset.org/abstracts/search?q=Nozha%20Chakroun"> Nozha Chakroun</a>, <a href="https://publications.waset.org/abstracts/search?q=Salima%20Daoud"> Salima Daoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20Keskes"> Leila Keskes</a>, <a href="https://publications.waset.org/abstracts/search?q=Tarek%20Rebai"> Tarek Rebai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Recurrent pregnancy loss (RPL) defined as two or more pregnancy losses, is a serious clinical problem. Methylene-tetrahydro-folate-reductase (MTHFR) polymorphisms, commonly the variant C677T is recognized as an inherited thrombophilia which might affect embryonic development and pregnancy success and cause pregnancy complications as RPL. Material and Methods DNA was extracted from peripheral blood samples and PCR-RFLP was performed for the molecular diagnosis of the C677T MTHFR polymorphism among 70 patients (35 couples) with more than 2 fetal losses. Aims and Objective: The aim of this study is to determine the frequency of MTHFR C677T among Tunisian couples with RPL and to critically analyze the available literature on the importance of MTHFR polymorphism testing in the management of RPL. Result and comments: No C677T mutation was detected in the carriers of RPL. This result would be related to sample size and to different criteria (number of abortion), - The association between MTHFR polymorphisms and pregnancy complications has been reported but with controversial results. - A lack of evidence for MTHFR polymorphism testing previously recommended by ACMG (American College of Medical medicine). Our study highlights the importance of screening of MTHFR polymorphism since the real impact of such thrombotic molecular defect on the pregnancy outcome is evident. - Folic supplementation of these patients during pregnancy can prevent such complications and lead to a successful pregnancy outcome. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=methylenetetrahydrofolate%20reductase" title="methylenetetrahydrofolate reductase">methylenetetrahydrofolate reductase</a>, <a href="https://publications.waset.org/abstracts/search?q=C677T" title=" C677T"> C677T</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrent%20pregnancy%20loss" title=" recurrent pregnancy loss"> recurrent pregnancy loss</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20testing" title=" genetic testing"> genetic testing</a> </p> <a href="https://publications.waset.org/abstracts/44932/the-mthfr-c677t-polymorphism-screening-a-challenge-in-recurrent-pregnancy-loss" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44932.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">306</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">5189</span> Recurrent Fevers with Weight Gain - Possible Rapid onset Obesity with Hypoventilation, Hypothalamic Dysfunction and Autonomic Dysregulation Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lee%20Rui">Lee Rui</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajeev%20Ramachandran"> Rajeev Ramachandran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The approach to recurrent fevers in the paediatric or adolescent age group is not a straightforward one. Causes range from infectious diseases to rheumatological conditions to endocrinopathies, and are usually accompanied by weight loss rather than weight gain. We present an interesting case of a 16-year-old girl brought by her mother to the General Pediatrics Clinic for concerns of recurrent fever paired with significant weight gain over 1.5 years, with no identifiable cause found despite extensive work-up by specialists ranging from Rheumatologists to Oncologists. This case provides a learning opportunity on the approach to weight gain paired with persistent fevers in a paediatric population, one which is not commonly encountered and prompts further evaluation and consideration of less common diagnoses. In a span of 2 years, the girl’s weight had increased from 55 kg at 13 years old (75th centile) to 73.9 kg at 16 years old (>97th centile). About 1 year into her rapid weight gain, she started developing recurrent fevers of documented temperatures > 37.5 – 38.6 every 2-3 days, resulting in school absenteeism when she was sent home after temperature-taking in school found her to be febrile. The rapid onset of weight gain paired with unexplained fevers prompted the treating physician to consider the diagnosis of ROHHAD syndrome. Rapid onset obesity with hypoventilation, hypothalamic dysfunction and autonomic dysregulation (ROHHAD) syndrome is a rare disorder first described in 2007. It is characterized by dysfunction of the autonomic and endocrine system, characterized by hyperphagia and rapid-onset weight gain. This rapid weight gain is classically followed by hypothalamic manifestations with neuroendocrine deficiencies, hypo-ventilatory breathing abnormalities, and autonomic dysregulation. ROHHAD is challenging to diagnose with and diagnosis is made based mostly on clinical judgement. However if truly diagnosed, the condition is characterized by high morbidity and mortality rates. Early recognition of sleep disorders breathing and targeted therapeutic interventions helps limit morbidity and mortality associated with ROHHAD syndrome. This case poses an interesting diagnostic challenge and a diagnosis of ROHHAD has to be considered, given the serious complications that can come with disease progression while conditions such as Munchausen’s or drug fever remain as diagnoses of exclusion until we have exhausted all other possible conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pediatrics" title="pediatrics">pediatrics</a>, <a href="https://publications.waset.org/abstracts/search?q=endocrine" title=" endocrine"> endocrine</a>, <a href="https://publications.waset.org/abstracts/search?q=weight%20gain" title=" weight gain"> weight gain</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrent%20fever" title=" recurrent fever"> recurrent fever</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescent" title=" adolescent"> adolescent</a> </p> <a href="https://publications.waset.org/abstracts/156376/recurrent-fevers-with-weight-gain-possible-rapid-onset-obesity-with-hypoventilation-hypothalamic-dysfunction-and-autonomic-dysregulation-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156376.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">107</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">5188</span> Role of Apolipoprotein E Polymorphism on the Onset of Inflammatory Bowel Disease in Saudi Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ebtissam%20Saleh%20Al-Meghaiseeb">Ebtissam Saleh Al-Meghaiseeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulaziz%20Al%20Masood"> Abdulaziz Al Masood</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulrahman%20Al-Robayan"> Abdulrahman Al-Robayan</a>, <a href="https://publications.waset.org/abstracts/search?q=Reem%20Al-Amro"> Reem Al-Amro</a>, <a href="https://publications.waset.org/abstracts/search?q=Misbahul%20Arfin"> Misbahul Arfin</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulrahman%20Al%20Asmari"> Abdulrahman Al Asmari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: The objective of this study was to evaluate the role of apolipoprotein E (APOE) polymorphism on the onset of inflammatory bowel disease (IBD) in Saudi patients. Methods: APOE gene was genotyped to evaluate the frequencies of the alleles and genotypes in Saudi subjects, including IBD patients (n=200) and matched controls (n=200), using APOE StripAssayTM kit (ViennaLab Labordiagnostika GmbH, Vienna, Austria). Results: The frequencies of alleles and genotypes of APOE differed in patients and controls. The APOE allele ε2 and ε4, genotype ε2/ε3 and ε2/ε4 were significantly higher in the IBD patients than the healthy controls. The frequencies of ε3 allele and ε3/ε3 genotype were higher in the control group as compared to patients. The higher prevalence of allele ε2 and ε4 allele in patients compared to that in controls suggested that ε2 and ε4 alleles may increase the risk of IBD. Results also indicated that APOE ε4 allele was associated with early age at onset of IBD. On the other hand, the decreased frequencies of ε3 allele and ε3/ε3 genotype in patients as compared to those in the controls suggested a protective effect of APOE ε3 for IBD susceptibility. In this study, the frequency distribution of APOE alleles and genotypes was not affected by the gender or type of IBD (familial or sporadic). Conclusion: This study indicates that APOE polymorphism plays a significant role in developing IBD and early age of onset in Saudi patients. However, further studies with large-size sample are warranted to confirm this relationship. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=APOE" title="APOE">APOE</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=IBD" title=" IBD"> IBD</a>, <a href="https://publications.waset.org/abstracts/search?q=saudis" title=" saudis"> saudis</a> </p> <a href="https://publications.waset.org/abstracts/156209/role-of-apolipoprotein-e-polymorphism-on-the-onset-of-inflammatory-bowel-disease-in-saudi-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156209.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">112</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">5187</span> Recurrence of Pterygium after Surgery and the Effect of Surgical Technique on the Recurrence of Pterygium in Patients with Pterygium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luksanaporn%20Krungkraipetch">Luksanaporn Krungkraipetch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A pterygium is an eye surface lesion that begins in the limbal conjunctiva and progresses to the cornea. The lesion is more common in the nasal limbus than in the temporal, and it has a distinctive wing-like aspect. Indications for surgery, in decreasing order of significance, are grown over the corneal center, decreased vision due to corneal deformation, documented growth, sensations of discomfort, and aesthetic concerns. Recurrent pterygium results in the loss of time, the expense of therapy, and the potential for vision impairment. The objective of this study is to find out how often the recurrence of pterygium after surgery occurs, what effect the surgery technique has, and what causes them to come back in people with pterygium. Materials and Methods: Observational case control in retrospect: the study involves a retrospective analysis of 164 patient samples. Data analysis is descriptive statistics analysis, i.e., basic data details about pterygium surgery and the risk of recurrent pterygium. For factor analysis, the inferential statistics odds ratio (OR) and 95% confidence interval (CI) ANOVA are utilized. A p-value of 0.05 was deemed statistically important. Results: The majority of patients, according to the results, were female (60.4%). Twenty-four of the 164 (14.6%) patients who underwent surgery exhibited recurrent pterygium. The average age is 55.33 years old. Postoperative recurrence was reported in 19 cases (79.3%) of bare sclera techniques and five cases (20.8%) of conjunctival autograft techniques. The recurrence interval is 10.25 months, with the most common (54.17 percent) being 12 months. In 91.67 percent of cases, all follow-ups are successful. The most common recurrence level is 1 (25%). A surgical complication is a subconjunctival hemorrhage (33.33 percent). Comparing the surgeries done on people with recurrent pterygium didn't show anything important (F = 1.13, p = 0.339). Age significantly affected the recurrence of pterygium (95% CI, 6.79-63.56; OR = 20.78, P 0.001). Conclusion: This study discovered a 14.6% rate of pterygium recurrence after pterygium surgery. Across all surgeries and patients, the rate of recurrence was four times higher with the bare sclera method than with conjunctival autograft. The researchers advise selecting a more conventional surgical technique to avoid a recurrence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pterygium" title="pterygium">pterygium</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrence%20pterygium" title=" recurrence pterygium"> recurrence pterygium</a>, <a href="https://publications.waset.org/abstracts/search?q=pterygium%20surgery" title=" pterygium surgery"> pterygium surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=excision%20pterygium" title=" excision pterygium"> excision pterygium</a> </p> <a href="https://publications.waset.org/abstracts/160557/recurrence-of-pterygium-after-surgery-and-the-effect-of-surgical-technique-on-the-recurrence-of-pterygium-in-patients-with-pterygium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160557.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">88</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">5186</span> Trehalose-Based Nanocarriers for Alleviation of Inflammation in Colitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wessam%20H.%20Abd-Elsalam">Wessam H.

Some studies reported their advantageous effect in decreasing inflammation, and other studies reported that their use is associated with colitis aggravation. This study aimed to use specifically formulated trehalose-based nano-carriers that targets the colon in an attempt to alleviate inflammation caused by NSAIDs. L-α-phosphatidylcholine (PL), trehalose, and transcutol were used to prepare the trehalosomes (THs), which were also loaded with Tenoxicam(TXM) as a model NSAID. To optimize the formulation variables, a full 23 factorial design, using Design-Expert® software, was performed. The optimized formulation composed of trehalose: PL at a weight ratio of 1:1, 377.72 mg transcutol, and sonicated for 4 min, possessed a spherical shape with a size of 268.61 nm and EE% of 97.83% and released 70.22% of its drug content over 24 h. The superior protective action of TXM loaded THs compared to TXM suspension and drug-free THs was shown by the inhibition of the inflammatory biomarkers, namely; IL-1ß, IL-6, and TNF-alpha levels, as well as oxidative stress markers, measured as GSH and MDA. Improved histopathology of the colonic tissue in male New Zealand rabbits also confirmed the superiority of the TXM loaded THs compared to the unformulated drug or the drug free nano-carriers. Our findings highlight the prosperous role of THs in colon targeting and its anti-inflammatory characteristics in guarding against possible NSAIDs-driven exacerbation of colitis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20bowel%20disease" title="inflammatory bowel disease">inflammatory bowel disease</a>, <a href="https://publications.waset.org/abstracts/search?q=trehalose" title=" trehalose"> trehalose</a>, <a href="https://publications.waset.org/abstracts/search?q=trehalosomes" title=" trehalosomes"> trehalosomes</a>, <a href="https://publications.waset.org/abstracts/search?q=colon%20targeting" title=" colon targeting"> colon targeting</a> </p> <a href="https://publications.waset.org/abstracts/149309/trehalose-based-nanocarriers-for-alleviation-of-inflammation-in-colitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149309.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">138</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">5185</span> Design of H-Shape X-band Application Electrically Small Antenna</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Riki%20H.%20Patel">Riki H.

A small wind turbine blade is designed, fabricated and tested. The power performance of small horizontal axis wind turbines is simulated in details using Computational Fluid Dynamic (CFD). The three-dimensional CFD models are presented using ANSYS-CFX v13 software for predicting the performance of a small horizontal axis wind turbine. The simulation results are compared with the experimental data measured from a small wind turbine model, which designed according to a vehicle-based test system. The analysis of wake effect and aerodynamic of the blade can be carried out when the rotational effect was simulated. Finally, comparison between experimental, numerical and analytical performance has been done. The comparison is fairly good. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small%20wind%20turbine" title="small wind turbine">small wind
