the development of motor vehicles is increasing the number of pollutants in the air. One of the substances that cause serious health problems is NO2. The health impacts arising from exposure to NO2 include pulmonary function impairment. The purpose of this study was to determine the relationship of NO2 exposure on the incidence of pulmonary function impairment. Methods: We are using a cross-sectional study design with 110 traffic police who were divided into two groups: exposed (police officers working on the highway) and the unexposed group (police officers working in the office). Election subject convenient sampling carried out in each group to the minimum number of samples met. Results: The results showed that the average NO2 in the exposed group was 18.72 ppb and unexposed group is 4.14 ppb. Pulmonary dysfunction on exposed and unexposed groups showed that FVC (Forced Vital Capacity) value are 88.68 and 90.27. And FEV1 (Forced Expiratory Volume in One) value are 94.9 and 95.16. Some variables like waist circumference, Body Mass Index, Visceral Fat, and Fat has associated with the incidence of Pulmonary Dysfunction (p < 0.05). Conclusion: Health monitoring is needed to decreasing health risk in Policeman. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NO2" title="NO2">NO2</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20dysfunction" title=" pulmonary dysfunction"> pulmonary dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=police%20traffic" title=" police traffic"> police traffic</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakarta" title=" Jakarta"> Jakarta</a> </p> <a href="https://publications.waset.org/abstracts/62743/no2-exposure-effect-on-the-occurrence-of-pulmonary-dysfunction-the-police-traffic-in-jakarta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62743.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">256</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> The Role of Pulmonary Resection in Complicated Primary Pediatric Pulmonary Tuberculosis: An Evidence-Based Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hendra%20Wibowo">Hendra Wibowo</a>, <a href="https://publications.waset.org/abstracts/search?q=Suprayitno%20Wardoyo"> Suprayitno Wardoyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhama%20Shinta"> Dhama Shinta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Pediatric pulmonary tuberculosis (TB) incidence was increasing, with many undetected cases. In complicated TB, treatment should consist of returning pulmonary function, preventing further complications, and eliminating bacteria. Complicated TB management was still controversial, and surgery was one of the treatments that should be evaluated in accordance with its role in the treatment of complicated TB. Method: This study was an evidence-based case report. The database used for the literature search were Cochrane, Medline, Proquest, and ScienceDirect. Keywords for the search were ‘primary pulmonary tuberculosis’, ‘surgery’, ‘lung resection’, and ‘children’. Inclusion criteria were studies in English or Indonesian, with children under 18 years old as subject, and full-text articles available. The assessment was done according to Oxford Centre for evidence-based medicine 2011. Results: Six cohort studies were analyzed. Surgery was indicated for patients with complicated TB that were unresponsive towards treatment. It should be noted that the experiments were done before the standard WHO antituberculosis therapy was applied; thus, the result may be different from the current application. Conclusion: Currently, there was no guideline on pulmonary resection. However, surgery yielded better mortality and morbidity in children with complicated pulmonary TB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pediatric" title="pediatric">pediatric</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary" title=" pulmonary"> pulmonary</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=therapy" title=" therapy"> therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a> </p> <a href="https://publications.waset.org/abstracts/108284/the-role-of-pulmonary-resection-in-complicated-primary-pediatric-pulmonary-tuberculosis-an-evidence-based-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108284.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">106</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> Impact of Pulmonary Rehabilitation on Respiratory Parameters in Interstitial Lung Disease Patients: A Tertiary Care Hospital Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vivek%20Ku">Vivek Ku</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20K.%20Janmeja"> A.

Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: Pulmonary rehabilitation plays a key role in management of chronic lung diseases. However, pulmonary rehabilitation is an underused modality in the management of interstitial lung disease (ILD). This is because limited information is available in literature and no data is available from India on this issue so far. The study was carried out to evaluate the role of pulmonary rehabilitation on respiratory parameters in ILD patients. Methods: The present study was a prospective randomized non-blind case control study. Total of 40 ILD patients were randomized into 2 groups of 20 patients each viz ‘pulmonary rehabilitation group’ and ‘control group’. Pulmonary rehabilitation group underwent 8 weeks pulmonary rehabilitation (PR) along with medical management as per guidelines and the control group was advised only medical management. Results: Mean age in case group was 59.15 ± 10.39 years and in control group was 62.10 ± 14.54 years. The case and the control groups were matched for age and sex. Mean MRC grading at the end of 8 weeks showed significant improvement in the case group as compared to control group (p= 0.011 vs p = 0.655). Similarly, mean St. George Respiratory Questionnaire (SGRQ) score also showed significant improvement in pulmonary rehabilitation group at the end of the study (p= 0.001 vs p= 0.492). However, FEV1 and FVC had no significant change in the case and control group. Similarly, blood gases also did not show any significant difference in the group. Conclusion: Pulmonary rehabilitation improves breathlessness and thereby improves quality of life in the patients suffering from ILD. However, the pulmonary function values and blood gases are unaffected by pulmonary rehabilitation. Clinical Implications: Further large scale multicentre study is needed to ascertain the association. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ILD" title="ILD">ILD</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20rehabilitation" title=" pulmonary rehabilitation"> pulmonary rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20functions" title=" pulmonary functions"> pulmonary functions</a> </p> <a href="https://publications.waset.org/abstracts/39543/impact-of-pulmonary-rehabilitation-on-respiratory-parameters-in-interstitial-lung-disease-patients-a-tertiary-care-hospital-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39543.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">270</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> Changes in Pulmonary Functions in Diabetes Mellitus Type 2</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Anand">N.

Verma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Diabetes mellitus is a group of disorders characterized by hyperglycemia and associated with microvascular and macrovascular complications. Among the lesser known complications is the involvement of respiratory system. Changes in pulmonary volume, diffusion and elastic properties of lungs as well as the performance of the respiratory muscles lead to a restrictive pattern in lung functions. The present study was aimed to determine the changes in various parameters of pulmonary function tests amongst patients with Type 2 Diabetes Mellitus and also try to study the effect of duration of Diabetes Mellitus on pulmonary function tests. Methods: It was a cross sectional study performed at Dr Baba Saheb Ambedkar Hospital and Medical College in, Delhi, A Tertiary care referral centre which included 200 patients divided into 2 groups. The first group included diagnosed patients with diabetes and the second group included controls. Cases and controls symptomatic for any acute or chronic Respiratory or Cardiovascular illness or a history of smoking were excluded. Both the groups were subjected to spirometry to evaluate for the pulmonary function tests. Result: The mean Forced Vital Capacity (FVC), Forced Expiratory Volume in first second (FEV1), Peak Expiratory Flow Rate(PEFR) was found to be significantly decreased ((P < 0.001) as compared to controls while the mean ratio of Forced Expiratory Volume in First second to Forced Vital Capacity was not significantly decreased( p>0.005). There was no correlation seen with duration of the disease. Conclusion: Forced Vital Capacity (FVC), Forced Expiratory Volume in first second (FEV1), Peak Expiratory Flow Rate(PEFR) were found to be significantly decreased in patients of Diabetes mellitus while ratio of Forced Expiratory Volume in First second to Forced Vital Capacity (FEV1/FVC) was not significantly decreased. The duration of Diabetes mellitus was not found to have any statistically significant effect on Pulmonary function tests (p > 0.005). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title="diabetes mellitus">diabetes mellitus</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20function%20tests" title=" pulmonary function tests"> pulmonary function tests</a>, <a href="https://publications.waset.org/abstracts/search?q=forced%20vital%20capacity" title=" forced vital capacity"> forced vital capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=forced%20expiratory%20volume%20in%20first%20second" title=" forced expiratory volume in first second"> forced expiratory volume in first second</a> </p> <a href="https://publications.waset.org/abstracts/39865/changes-in-pulmonary-functions-in-diabetes-mellitus-type-2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39865.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">368</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">5184</span> A Case of Postpartum Pulmonary Edema Induced by Oxytocin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=May%20Zaw">May Zaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Amber%20Latif"> Amber Latif</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Lim"> William Lim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Postpartum dyspnea can be due to many causes, such as pulmonary embolism, amniotic fluid embolism, and peripartum cardiomyopathy, but less frequently due to acute pulmonary edema. The incidence of acute pulmonary edema during pregnancy and in the postpartum period has been estimated to be around 0.08%. About half of the cases are attributed to tocolytic therapy. Herein, we present a case of a young woman presenting with acute hypoxia after induction of labor with oxytocin and found to have acute pulmonary edema. This case aims to illustrate and add to a growing body of literature regarding oxytocin-induced acute pulmonary edema and highlights the importance of recognizing the rare complication of oxytocin and necessary interventions to avoid complications. Oxytocin-induced pulmonary edema is a relatively uncommon condition, but physicians should have a high index of suspicion to initiate timely intervention and avoid fetal complications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pulmonary" title="pulmonary">pulmonary</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=oxytocin" title=" oxytocin"> oxytocin</a>, <a href="https://publications.waset.org/abstracts/search?q=postpartum" title=" postpartum"> postpartum</a> </p> <a href="https://publications.waset.org/abstracts/153892/a-case-of-postpartum-pulmonary-edema-induced-by-oxytocin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153892.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">90</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">5183</span> A Theoretical to Conceptual Paper: The Use of Phosphodiesterase Inhibitors, Endothelin Receptor Antagonists and/or Prostacyclin Analogs in Acute Pulmonary Embolism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ryan%20M.%20Monti">Ryan M.

Based on the premise that dilating the pulmonary artery will decrease the pulmonary vascular pressure, while simultaneously decreasing the aggregation of platelets, it can be hypothesized that increased blood flow through the pulmonary artery will decrease right heart strain and subsequent morbidity and mortality. While this theory has yet to be formally studied, the recommendations for treating massive pulmonary embolism with phosphodiesterase inhibitors, endothelin receptor antagonists, and/or prostacyclin analogs in conjunction with the current standards of care in massive pulmonary embolism should be formally studied. In particular, patients with massive PE who are unable to undergo thrombolysis/surgical intervention may be the ideal population to study the use of these treatments to determine any decrease in mortality and morbidity (short term and long term). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20pulmonary%20thromboembolism" title="acute pulmonary thromboembolism">acute pulmonary thromboembolism</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment%20of%20pulmonary%20embolism" title=" treatment of pulmonary embolism"> treatment of pulmonary embolism</a>, <a href="https://publications.waset.org/abstracts/search?q=use%20of%20phosphodiesterase%20inhibitors" title=" use of phosphodiesterase inhibitors"> use of phosphodiesterase inhibitors</a>, <a href="https://publications.waset.org/abstracts/search?q=endothelin%20receptor%20antagonists" title=" endothelin receptor antagonists"> endothelin receptor antagonists</a>, <a href="https://publications.waset.org/abstracts/search?q=prostacyclin%20analogs%20in%20PE" title=" prostacyclin analogs in PE"> prostacyclin analogs in PE</a> </p> <a href="https://publications.waset.org/abstracts/49295/a-theoretical-to-conceptual-paper-the-use-of-phosphodiesterase-inhibitors-endothelin-receptor-antagonists-andor-prostacyclin-analogs-in-acute-pulmonary-embolism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49295.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">225</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">5182</span> Pulmonary Valve Papillary Fibroelastoma: A Case Report of a Fibroelastoma Presenting as a Pulmonary Embolism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frazer%20Kirk">Frazer Kirk</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Yong"> Matthew Yong</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Williams"> Peter Williams</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrie%20Strobel"> Andrie Strobel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pulmonary valve papillary fibroelastoma is an exceedingly rare pathology. The experience and literature regarding them are largely anecdotal and based on sporadic, single case reports. Throughout their known history, two features remain salient that they are classically asymptomatic and found incidentally. The demographic profile of those affected is unclear, as reports regarding those affected are mixed, and there is no clear gender or age predominance, although there is some suggestion of a predisposition to affect females. Nor has there been a well-structured epidemiological study of the entity. Interestingly they are becoming more common on peri-mortum examination.

Additionally, it looks into the relationship between pulmonary dysfunction in workers and XRCC1 gene polymorphisms. 110 exposed workers and 58 non-exposed workers participated in the study. Measurements have been conducted on SO₂, NO₂, and particulate particles. Pulmonary function was tested. Eosinophil cationic protein (ECP), C-reactive protein (CRP), matrix metalloproteinase-1 (MMP-1), interleukin 6 (IL6), GM-CSF, X-Ray Repair Cross Complementing 1 (XRCC1) protein, and genotyping of XRCC1 gene polymorphisms were examined. Results: The annual average concentrations of (PM₂.₅, PM₁₀, TSP, SO₂, and NO₂) were lower than the permissible limit. The areas around ovens, evaporators, and cold rolling mills exhibited the highest amounts. The majority of employees in these departments had impaired lung function. With longer exposure times, the exposed group's FEV1% and FVC% considerably reduced. The exposed workers had considerably higher XRCC1 levels. The evaluated inflammatory biomarkers showed no statistically significant difference. Conclusion: Aluminum workers are at risk of developing respiratory disorders. The level of serum XRCC1 may act as a biomarker that might be very useful for detecting susceptible workers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum%20industry" title="aluminum industry">aluminum industry</a>, <a href="https://publications.waset.org/abstracts/search?q=particulate%20matter" title=" particulate matter"> particulate matter</a>, <a href="https://publications.waset.org/abstracts/search?q=SO%E2%82%82" title=" SO₂"> SO₂</a>, <a href="https://publications.waset.org/abstracts/search?q=NO%E2%82%82" title=" NO₂"> NO₂</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20function" title=" lung function"> lung function</a>, <a href="https://publications.waset.org/abstracts/search?q=XRCC1%20gene%20polymorphism" title=" XRCC1 gene polymorphism"> XRCC1 gene polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=XRCC1%20protein" title=" XRCC1 protein"> XRCC1 protein</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20biomarkers" title=" inflammatory biomarkers"> inflammatory biomarkers</a> </p> <a href="https://publications.waset.org/abstracts/193901/association-of-airborne-emissions-with-pulmonary-dysfunction-xrcc1-gene-polymorphism-and-some-inflammatory-markers-in-aluminum-workers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193901.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">11</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">5180</span> CT-Scan Transition of Pulmonary Edema Due to Water-Soluble Paint Inhalation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masashi%20Kanazawa">Masashi Kanazawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Takaaki%20Nakano"> Takaaki Nakano</a>, <a href="https://publications.waset.org/abstracts/search?q=Masaaki%20Takemoto"> Masaaki Takemoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomonori%20Imamura"> Tomonori Imamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamiko%20Sugimura"> Mamiko Sugimura</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshitaka%20Ito"> Toshitaka Ito</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: We experienced a massive disaster due to inhalation of water-soluble paint. Sixteen patients were brought to our emergency room, and pulmonary edema was revealed on the CT images of 12 cases. Purpose: Transition of chest CT-scan findings in cases with pulmonary edema was examined. Method: CT-scans were performed on the 1st, 2nd, 5th, and 19th days after the inhalation event. Patients whose pulmonary edema showed amelioration or exacerbation were classified into the improvement or the exacerbation group, respectively. Those with lung edema findings appearing at different sites after the second day were classified into the changing group. Results: Eight, one and three patients were in the improvement, exacerbation and changing groups, respectively. In all cases, the pulmonary edema had disappeared from CT images on the 19th day after the inhalation event. Conclusion: Inhalation of water-soluble paints is considered to be relatively safe. However, our observations in these emergency cases suggest that, even if pulmonary edema is not severe immediately after the exposure, new lesions may appear later and existing lesions may worsen. Follow-up imaging is thus necessary for about two weeks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CT%20scan" title="CT scan">CT scan</a>, <a href="https://publications.waset.org/abstracts/search?q=intoxication" title=" intoxication"> intoxication</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20edema" title=" pulmonary edema"> pulmonary edema</a>, <a href="https://publications.waset.org/abstracts/search?q=water-soluble%20paint" title=" water-soluble paint"> water-soluble paint</a> </p> <a href="https://publications.waset.org/abstracts/74622/ct-scan-transition-of-pulmonary-edema-due-to-water-soluble-paint-inhalation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74622.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">173</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">5179</span> Bronchospasm Analysis Following the Implementation of a Program of Maximum Aerobic Exercise in Active Men</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sajjad%20Shojaeidoust">Sajjad Shojaeidoust</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Ghanbarzadeh"> Mohsen Ghanbarzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolhamid%20Habibi"> Abdolhamid Habibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Exercise-induced bronchospasm (EIB) is a transitory condition of airflow obstruction that is associated with physical activities. It is noted that high ventilation can lead to an increase in the heat and reduce in the moisture in airways resistance of trachea. Also causes of pathophysiological mechanism are EIB. Accordingly, studying some parameters of pulmonary function (FVC, FEV1) among active people seems quintessential. The aim of this study was to analyze bronchospasm following the implementation of a program of maximum aerobic exercise in active men at Chamran University of Ahwaz. Method: In this quasi-experimental study, the population consisted of all students at Chamran University. Among from 55 participants, of which, 15 were randomly selected as the experimental group. In this study, the size of the maximum oxygen consumption was initially measured, and then, based on the maximum oxygen consumed, the active individuals were identified. After five minutes’ warm-up, Strand treadmill exercise test was taken (one session) and pulmonary parameters were measured at both pre- and post-tests (spirometer). After data normalization using KS and non-normality of the data, the Wilcoxon test was used to analyze the data. The significance level for all statistical surveys was considered p≤0/05. Results: The results showed that the ventilation factors and bronchospasm (FVC, FEV1) in the pre-test and post-test resulted in no significant difference among the active people (p≥0/05). Discussion and conclusion: Based on the results observed in this study, it appears that pulmonary indices in active individuals increased after aerobic test. The increase in this indicator in active people is due to increased volume and elasticity of the lungs as well. In other words, pulmonary index is affected by rib muscles. It is considered that progress over respiratory muscle strength and endurance has raised FEV1 in the active cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerobic%20active%20maximum" title="aerobic active maximum">aerobic active maximum</a>, <a href="https://publications.waset.org/abstracts/search?q=bronchospasm" title=" bronchospasm"> bronchospasm</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20function" title=" pulmonary function"> pulmonary function</a>, <a href="https://publications.waset.org/abstracts/search?q=spirometer" title=" spirometer"> spirometer</a> </p> <a href="https://publications.waset.org/abstracts/55779/bronchospasm-analysis-following-the-implementation-of-a-program-of-maximum-aerobic-exercise-in-active-men" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55779.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">287</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">5178</span> Validation Pulmonary Embolus Severity Index Score Early Mortality Rate at 1, 3, 7 Days in Patients with a Diagnosis of Pulmonary Embolism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Marinus%20Batt">Nicholas Marinus Batt</a>, <a href="https://publications.waset.org/abstracts/search?q=Angus%20Radford"> Angus Radford</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Saraya"> Khaled Saraya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pulmonary Embolus Severity Index (PESI) score is a well-validated decision-making score grading mortality rates (MR) in patients with a suspected or confirmed diagnosis of pulmonary embolism (PE) into 5 classes.

The aim of this study was to estimate the completeness of pulmonary tuberculosis cases confirmed by two sources of hospital registrations and surveillance systems in 2013 in Nakhon Pathom province, Thailand. Several estimators of population size were considered: the Lincoln-Petersen estimator, the Chapman estimator, the Chao’s lower bound estimator, the Zelterman’s estimator, etc. We focus on the Chapman and Chao’s lower bound estimators for estimating the completeness of pulmonary tuberculosis from two sources. The retrieved pulmonary tuberculosis data from two sources were analyzed and bootstrapped for 30 samples, with 241 observations from source 1 and 305 observations from source 2 per sample, for additional exploration of the completeness of pulmonary tuberculosis. The results from the original data show that the Chapman’s estimator gave the estimation of a total 360 (95% CI: 349-371) pulmonary tuberculosis cases, resulting in 57% estimated completeness cases. But the Chao’s lower bound estimator estimated the total of 365 (95% CI: 354-376) pulmonary tuberculosis cases and its estimated completeness cases was 55.9%. For the results from bootstrap samples, the Chapman and the Chao’s lower bound estimators gave an estimated 347 (95% CI: 309-385) and 353 (95% CI: 315-390) pulmonary tuberculosis cases, respectively. If for two sources recoding systems are available, record-linkage and capture-recapture analysis can be useful for estimating the completeness of different registration system. Both Chapman and Chao’s lower bound estimator approaches produce very close estimates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capture-recapture" title="capture-recapture">capture-recapture</a>, <a href="https://publications.waset.org/abstracts/search?q=Chao" title=" Chao"> Chao</a>, <a href="https://publications.waset.org/abstracts/search?q=Chapman" title=" Chapman"> Chapman</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20tuberculosis" title=" pulmonary tuberculosis"> pulmonary tuberculosis</a> </p> <a href="https://publications.waset.org/abstracts/23818/capture-recapture-to-estimate-completeness-of-pulmonary-tuberculosis-with-two-sources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23818.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">516</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">5176</span> Pulmonary Embolism Indicative of Myxoma of the Right Atrium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Kherraf">A.

The purpose of this observation is to report a rare case of myxoma of the right atrium revealed by pulmonary embolism. Observation: A 34-year-old patient with no history presented to the emergency room with sudden onset dyspnea. Clinical examination showed arterial pressure at 110/70mmHg, tachycardia at 110bpm, and 90% oxygen saturation. The ECG enrolled in incomplete right bundle branch block. The radio-thorax was normal. Echocardiography revealed the presence of a large homogeneous intra-OD mass, contiguous to the inter-atrial septum, prolapsing through the tricuspid valve, and causing mild tricuspid insufficiency, with dilation of the right ventricle and retained systolic function with PAPs estimated at 45mmHg. A chest scan was performed, revealing the presence of right segmental pulmonary embolism. The patient was put under anticoagulant and underwent surgical resection of the mass; its pathological examination concluded to a myxoma. The post-operative consequences were simple, without recurrence of the mass after one year follow-up. Discussion: Myxomas represent 50% of heart tumors. Most often, they originate in the left atrium, and more rarely in the right atrium or the ventricles. Myxoma of the right atrium can be responsible for life-threatening pulmonary embolism. The most predictive factor for embolization remains the morphology of the myxomas; papillary or villous myxomas are the most friable. Surgery is the standard treatment, with regular postoperative follow-up to detect recurrence. Conclusion: Myxomas of the right atrium are a rare location for these tumors. Pulmonary embolism is the main complication and should routinely involve careful study of the right chambers on echocardiography. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20embolism" title="pulmonary embolism">pulmonary embolism</a>, <a href="https://publications.waset.org/abstracts/search?q=myxoma" title=" myxoma"> myxoma</a>, <a href="https://publications.waset.org/abstracts/search?q=right%20atrium" title=" right atrium"> right atrium</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20tumors" title=" heart tumors "> heart tumors </a> </p> <a href="https://publications.waset.org/abstracts/130820/pulmonary-embolism-indicative-of-myxoma-of-the-right-atrium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130820.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5175</span> Collagen Deposition in Lung Parenchyma Driven by Depletion of LYVE-1+ Macrophages Protects Emphysema and Loss of Airway Function</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yinebeb%20Mezgebu%20Dagnachew">Yinebeb Mezgebu Dagnachew</a>, <a href="https://publications.waset.org/abstracts/search?q=Hwee%20Ying%20Lim"> Hwee Ying Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Liao%20Wupeng"> Liao Wupeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheau%20Yng%20Lim"> Sheau Yng Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Lim%20Sheng%20Jie%20Natalie"> Lim Sheng Jie Natalie</a>, <a href="https://publications.waset.org/abstracts/search?q=Veronique%20Angeli"> Veronique Angeli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Collagen is essential for maintaining lung structure and function, and its remodeling has been associated with respiratory diseases, including chronic obstructive pulmonary disease (COPD). However, the cellular mechanisms driving collagen remodeling and the functional implications of this process in the pathophysiology of pulmonary diseases remain poorly understood. Using a mouse model of Lyve-1 expressing macrophage depletion, we found that the absence of this subpopulation of tissue-resident macrophage led to the preferential deposition of type I collagen fibers around the alveoli and bronchi in the steady state. Further analysis by polarized light microscopy revealed that the collagen fibers accumulating in the lungs depleted of Lyve-1+ macrophages were thicker and crosslinked. A decrease in MMP-9 gene expression and proteolytic activity, together with an increase in Col1a1, Timp-3 and Lox gene expression, accompanied the collagen alterations. Next, we investigated the effect of the collagen remodeling on the pathophysiology of COPD and airway function in mouse lacking Lyve-1+ macrophage exposed chronically to cigarette smoke (CS), a well-established animal model of COPD. We showed that the deposition of collagen protected mouse against the destruction of alveoli (emphysema) and bronchi thickening after CS exposure and prevented loss of airway function. Thus, we demonstrate that interstitial Lyve-1+ macrophages regulate the composition, amount, and architecture of the collagen network in the lungs and that such collagen remodeling functionally impacts the development of COPD. This study further supports the potential of targeting collagen as a promising approach to treating respiratory diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lung" title="lung">lung</a>, <a href="https://publications.waset.org/abstracts/search?q=extracellular%20matrix" title=" extracellular matrix"> extracellular matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20obstructive%20pulmonary%20disease" title=" chronic obstructive pulmonary disease"> chronic obstructive pulmonary disease</a>, <a href="https://publications.waset.org/abstracts/search?q=matrix%20metalloproteinases" title=" matrix metalloproteinases"> matrix metalloproteinases</a>, <a href="https://publications.waset.org/abstracts/search?q=collagen" title=" collagen"> collagen</a> </p> <a href="https://publications.waset.org/abstracts/187346/collagen-deposition-in-lung-parenchyma-driven-by-depletion-of-lyve-1-macrophages-protects-emphysema-and-loss-of-airway-function" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187346.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">37</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">5174</span> Comparison of Multivariate Adaptive Regression Splines and Random Forest Regression in Predicting Forced Expiratory Volume in One Second</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20V.%20Pramila">P.

Mahesh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pulmonary Function Tests are important non-invasive diagnostic tests to assess respiratory impairments and provides quantifiable measures of lung function. Spirometry is the most frequently used measure of lung function and plays an essential role in the diagnosis and management of pulmonary diseases. However, the test requires considerable patient effort and cooperation, markedly related to the age of patients esulting in incomplete data sets. This paper presents, a nonlinear model built using Multivariate adaptive regression splines and Random forest regression model to predict the missing spirometric features. Random forest based feature selection is used to enhance both the generalization capability and the model interpretability. In the present study, flow-volume data are recorded for N= 198 subjects. The ranked order of feature importance index calculated by the random forests model shows that the spirometric features FVC, FEF 25, PEF,FEF 25-75, FEF50, and the demographic parameter height are the important descriptors. A comparison of performance assessment of both models prove that, the prediction ability of MARS with the `top two ranked features namely the FVC and FEF 25 is higher, yielding a model fit of R2= 0.96 and R2= 0.99 for normal and abnormal subjects. The Root Mean Square Error analysis of the RF model and the MARS model also shows that the latter is capable of predicting the missing values of FEV1 with a notably lower error value of 0.0191 (normal subjects) and 0.0106 (abnormal subjects). It is concluded that combining feature selection with a prediction model provides a minimum subset of predominant features to train the model, yielding better prediction performance. This analysis can assist clinicians with a intelligence support system in the medical diagnosis and improvement of clinical care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FEV" title="FEV">FEV</a>, <a href="https://publications.waset.org/abstracts/search?q=multivariate%20adaptive%20regression%20splines%20pulmonary%20function%20test" title=" multivariate adaptive regression splines pulmonary function test"> multivariate adaptive regression splines pulmonary function test</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20forest" title=" random forest"> random forest</a> </p> <a href="https://publications.waset.org/abstracts/27603/comparison-of-multivariate-adaptive-regression-splines-and-random-forest-regression-in-predicting-forced-expiratory-volume-in-one-second" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27603.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">310</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">5173</span> Cadaveric Study of Lung Anatomy: A Surgical Overview</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arthi%20Ganapathy">Arthi Ganapathy</a>, <a href="https://publications.waset.org/abstracts/search?q=Rati%20Tandon"> Rati Tandon</a>, <a href="https://publications.waset.org/abstracts/search?q=Saroj%20Kaler"> Saroj Kaler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: A thorough knowledge of variations in lung anatomy is of prime significance during surgical procedures like lobectomy, pneumonectomy, and segmentectomy of lungs. The arrangement of structures in the lung hilum act as a guide in performing such procedures. The normal pattern of arrangement of hilar structures in the right lung is eparterial bronchus, pulmonary artery, hyparterial bronchus and pulmonary veins from above downwards. In the left lung, it is pulmonary artery, principal bronchus and pulmonary vein from above downwards. The arrangement of hilar structures from anterior to posterior in both the lungs is pulmonary vein, pulmonary artery, and principal bronchus. The bronchial arteries are very small and usually the posterior most structures in the hilum of lungs. Aim: The present study aims at reporting the variations in hilar anatomy (arrangement and number) of lungs. Methodology: 75 adult formalin fixed cadaveric lungs from the department of Anatomy AIIMS New Delhi were observed for variations in the lobar anatomy. Arrangement of pulmonary hilar structures was meticulously observed, and any deviation in the pattern of presentation was recorded. Results: Among the 75 adult lung specimens observed 36 specimens were of right lung and the rest of left lung. Seven right lung specimens showed only 2 lobes with an oblique fissure dividing them and one left lung showed 3 lobes. The normal pattern of arrangement of hilar structures was seen in 22 right lungs and 23 left lungs. Rest of the lung specimens (14 right and 16 left) showed a varied pattern of arrangement of hilar structures. Some of them showed alterations in the sequence of arrangement of pulmonary artery, pulmonary veins, bronchus, and others in the number of these structures. Conclusion: Alterations in the pattern of arrangement of structures in the lung hilum are quite frequent. A compromise in knowledge of such variations will result in inadvertent complications like intraoperative bleeding during surgical procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fissures" title="fissures">fissures</a>, <a href="https://publications.waset.org/abstracts/search?q=hilum" title=" hilum"> hilum</a>, <a href="https://publications.waset.org/abstracts/search?q=lobes" title=" lobes"> lobes</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary" title=" pulmonary"> pulmonary</a> </p> <a href="https://publications.waset.org/abstracts/77925/cadaveric-study-of-lung-anatomy-a-surgical-overview" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77925.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">224</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">5172</span> Strategies For Management Of Massive Intraoperative Airway Haemorrhage Complicating Surgical Pulmonary Embolectomy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Bayfield">Nicholas Bayfield</a>, <a href="https://publications.waset.org/abstracts/search?q=Liam%20Bibo"> Liam Bibo</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaushelandra%20Rathore"> Kaushelandra Rathore</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucas%20Sanders"> Lucas Sanders</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Newman"> Mark Newman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> INTRODUCTION: Surgical pulmonary embolectomy is an established therapy for acute pulmonary embolism causing right heart dysfunction and haemodynamic instability. Massive intraoperative airway haemorrhage is a rare complication of pulmonary embolectomy. We present our institutional experience with massive airway haemorrhage complicating pulmonary embolectomy and discuss optimal therapeutic strategies. METHODS: A retrospective review of emergent surgical pulmonary embolectomy patients was undertaken. Cases complicated by massive intra-operative airway haemorrhage were identified. Intra- and peri-operative management strategies were analysed and discussed. RESULTS: Of 76 patients undergoing emergent or salvage pulmonary embolectomy, three cases (3.9%) of massive intraoperative airway haemorrhage were identified. Haemorrhage always began on weaning from cardiopulmonary bypass. Successful management strategies involved intraoperative isolation of the side of bleeding, occluding the affected airway with an endobronchial blocker, institution of veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) and reversal of anticoagulation. Running the ECMO without heparinisation allows coagulation to occur. Airway haemorrhage was controlled within 24 hours of operation in all patients, allowing re-institution of dual lung ventilation and decannulation from ECMO. One case in which positive end-expiratory airway pressure was trialled initially was complicated by air embolism. Although airway haemorrhage was controlled successfully in all cases, all patients died in-hospital for reasons unrelated to the airway haemorrhage. CONCLUSION: Massive intraoperative airway haemorrhage during pulmonary embolectomy is a rare complication with potentially catastrophic outcomes. Re-perfusion alveolar and capillary injury is the likely aetiology. With a systematic approach to management, airway haemorrhage can be well controlled intra-operatively and often resolves within 24 hours. Stopping blood flow to the pulmonary arteries and support of oxygenation by the institution of VA ECMO is important. This management has been successful in our 3 cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20embolectomy" title="pulmonary embolectomy">pulmonary embolectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiopulmonary%20bypass" title=" cardiopulmonary bypass"> cardiopulmonary bypass</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac%20surgery" title=" cardiac surgery"> cardiac surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20embolism" title=" pulmonary embolism"> pulmonary embolism</a> </p> <a href="https://publications.waset.org/abstracts/142008/strategies-for-management-of-massive-intraoperative-airway-haemorrhage-complicating-surgical-pulmonary-embolectomy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142008.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">176</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">5171</span> Design and Development of a Bi-Leaflet Pulmonary Valve</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Munirah%20Ismail">Munirah Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Joon%20Hock%20Yeo"> Joon Hock Yeo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Paediatric patients who require ventricular outflow tract reconstruction usually need valve construction to prevent valvular regurgitation. They would face problems like lack of suitable, affordable conduits and the need to undergo several operations in their lifetime due to the short lifespan of existing valves. Their natural growth and development are also of concern, even if they manage to receive suitable conduits. Current prosthesis including homografts, bioprosthetic valves, mechanical valves, and bovine jugular veins either do not have the long-term durability or the ability to adapt to the growth of such patients. We have developed a new design of bi-leaflet valve. This new technique accommodates patients’ annular size growth while maintaining valvular patency. A mock circulatory system was set up to assess the hemodynamic performance of the bi-leaflet pulmonary valve. It was found that the percentage regurgitation was acceptable and thus, validates this novel concept. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bi-leaflet%20pulmonary%20valve" title="bi-leaflet pulmonary valve">bi-leaflet pulmonary valve</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20heart%20valve" title=" pulmonary heart valve"> pulmonary heart valve</a>, <a href="https://publications.waset.org/abstracts/search?q=tetralogy%20of%20fallot" title=" tetralogy of fallot"> tetralogy of fallot</a>, <a href="https://publications.waset.org/abstracts/search?q=mock%20circulatory%20system" title=" mock circulatory system"> mock circulatory system</a> </p> <a href="https://publications.waset.org/abstracts/86147/design-and-development-of-a-bi-leaflet-pulmonary-valve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86147.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">162</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">5170</span> Algorithm for Quantification of Pulmonary Fibrosis in Chest X-Ray Exams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcela%20de%20Oliveira">Marcela de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Guilherme%20Giacomini"> Guilherme Giacomini</a>, <a href="https://publications.waset.org/abstracts/search?q=Allan%20Felipe%20Fattori%20Alves"> Allan Felipe Fattori Alves</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Luiza%20Menegatti%20Pavan"> Ana Luiza Menegatti Pavan</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Eugenia%20Dela%20Rosa"> Maria Eugenia Dela Rosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Antonio%20Bacchim%20Neto"> Fernando Antonio Bacchim Neto</a>, <a href="https://publications.waset.org/abstracts/search?q=Diana%20Rodrigues%20de%20Pina"> Diana Rodrigues de Pina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is estimated that each year one death every 10 seconds (about 2 million deaths) in the world is attributed to tuberculosis (TB). Even after effective treatment, TB leaves sequelae such as, for example, pulmonary fibrosis, compromising the quality of life of patients. Evaluations of the aforementioned sequel are usually performed subjectively by radiology specialists. Subjective evaluation may indicate variations inter and intra observers. The examination of x-rays is the diagnostic imaging method most accomplished in the monitoring of patients diagnosed with TB and of least cost to the institution. The application of computational algorithms is of utmost importance to make a more objective quantification of pulmonary impairment in individuals with tuberculosis. The purpose of this research is the use of computer algorithms to quantify the pulmonary impairment pre and post-treatment of patients with pulmonary TB. The x-ray images of 10 patients with TB diagnosis confirmed by examination of sputum smears were studied. Initially the segmentation of the total lung area was performed (posteroanterior and lateral views) then targeted to the compromised region by pulmonary sequel. Through morphological operators and the application of signal noise tool, it was possible to determine the compromised lung volume. The largest difference found pre- and post-treatment was 85.85% and the smallest was 54.08%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=algorithm" title="algorithm">algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=radiology" title=" radiology"> radiology</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=x-rays%20exam" title=" x-rays exam"> x-rays exam</a> </p> <a href="https://publications.waset.org/abstracts/39759/algorithm-for-quantification-of-pulmonary-fibrosis-in-chest-x-ray-exams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39759.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">418</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">5169</span> Trend and Incidence of Tuberculosis, Yemen, 2019 to 2021</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zainab%20A.%20Alaghbri">Zainab A.

The war in Yemen has led to the emergence of one of the worst humanitarian crises in the world. These circumstances may lead to exacerbate the situation of tuberculosis. This study aims to describe the trend and incidence of TB in north and east governorates, Yemen 2019-2021 and provide recommendations for interventions. A descriptive analysis was conducted during July to September 2022. Data of TB cases were obtained from the national tuberculosis program as soft copy. The Data included the TB case collected and diagnosed during 2019-2021. The data contains the following variables: Sex, age, governorates, smear-positive cases, extra-pulmonary cases, and treatment outcomes. 16791 TB cases were notified for an overall case notification rate 65.5/100000 for all forms (smear positive and Extra-pulmonary), There was a slightly declined in 2020 and 2021 by 1%. Both the pulmonary smear positive and Extra pulmonary rates were slightly decreased from 8.8 to 7.7 and 13.5 to 12.8 / 100, 000 populations respectively. For Tuberculosis cases by type of patient, the incidence of extra-pulmonary was the highest (12,9, 11.3 and 12,2/100000) over the three years. However, the incidence of pulmonary failure was the lowest. The majority of cases were in the age group 25-34. The overall treatment success rate for smear-positive patients was 88%. Of the 627 patients with documented unsuccessful outcomes (e.g., failure, death, and default), 165 (23%) died, 52 (8.3%) failed treatment, and 410 (65%) defaulted. Overall, the magnitude of tuberculosis decreased over the periods reviewed. The proportion of Extra-pulmonary TB was the highest. The success rate achieved after treatment was below the levels established by the WHO End Tuberculosis Strategy (90%). Failure to complete treatment may be responsible for the low success rate. Monitoring and addressing the risk factors that were associated with treatment outcomes and duration may help improve the likelihood of achieving favorable outcomes among cases of smear-positive pulmonary TB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title="tuberculosis">tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=trend" title=" trend"> trend</a>, <a href="https://publications.waset.org/abstracts/search?q=incidence" title=" incidence"> incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=yemen" title=" yemen"> yemen</a> </p> <a href="https://publications.waset.org/abstracts/171629/trend-and-incidence-of-tuberculosis-yemen-2019-to-2021" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171629.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">97</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">5168</span> High-Dimensional Single-Cell Imaging Maps Inflammatory Cell Types in Pulmonary Arterial Hypertension</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Selena%20Ferrian">Selena Ferrian</a>, <a href="https://publications.waset.org/abstracts/search?q=Erin%20Mccaffrey"> Erin Mccaffrey</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshie%20Saito"> Toshie Saito</a>, <a href="https://publications.waset.org/abstracts/search?q=Aiqin%20Cao"> Aiqin Cao</a>, <a href="https://publications.waset.org/abstracts/search?q=Noah%20Greenwald"> Noah Greenwald</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Robert%20Nicolls"> Mark Robert Nicolls</a>, <a href="https://publications.waset.org/abstracts/search?q=Trevor%20Bruce"> Trevor Bruce</a>, <a href="https://publications.waset.org/abstracts/search?q=Roham%20T.%20Zamanian"> Roham T.

However, comprehensive mapping of the immune landscape in pulmonary arteries (PAs) is necessary to understand how immune cell subsets interact to induce pulmonary vascular pathology. We used multiplexed ion beam imaging by time-of-flight (MIBI-TOF) to interrogate the immune landscape in PAs from idiopathic (IPAH) and hereditary (HPAH) PAH patients. Massive immune infiltration in I/HPAH was observed with intramural infiltration linked to PA occlusive changes. The spatial context of CD11c+DCs expressing SAMHD1, TIM-3 and IDO-1 within immune-enriched microenvironments and neutrophils were associated with greater immune activation in HPAH. Furthermore, CD11c-DC3s (mo-DC-like cells) within a smooth muscle cell (SMC) enriched microenvironment were linked to vessel score, proliferating SMCs, and inflamed endothelial cells. Experimental data in cultured cells reinforced a causal relationship between neutrophils and mo-DCs in mediating pulmonary arterial SMC proliferation. These findings merit consideration in developing effective immunotherapies for PAH. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20arterial%20hypertension" title="pulmonary arterial hypertension">pulmonary arterial hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=vascular%20remodeling" title=" vascular remodeling"> vascular remodeling</a>, <a href="https://publications.waset.org/abstracts/search?q=indoleamine%202-3-dioxygenase%201%20%28IDO-1%29" title=" indoleamine 2-3-dioxygenase 1 (IDO-1)"> indoleamine 2-3-dioxygenase 1 (IDO-1)</a>, <a href="https://publications.waset.org/abstracts/search?q=neutrophils" title=" neutrophils"> neutrophils</a>, <a href="https://publications.waset.org/abstracts/search?q=monocyte-derived%20dendritic%20cells" title=" monocyte-derived dendritic cells"> monocyte-derived dendritic cells</a>, <a href="https://publications.waset.org/abstracts/search?q=BMPR2%20mutation" title=" BMPR2 mutation"> BMPR2 mutation</a>, <a href="https://publications.waset.org/abstracts/search?q=interferon%20gamma%20%28IFN-%CE%B3%29" title=" interferon gamma (IFN-γ)"> interferon gamma (IFN-γ)</a> </p> <a href="https://publications.waset.org/abstracts/156849/high-dimensional-single-cell-imaging-maps-inflammatory-cell-types-in-pulmonary-arterial-hypertension" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156849.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">173</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">5167</span> Bronchoscopy and Genexpert in the Diagnosis of Pulmonary Tuberculosis in the Indian Private Health Sector: A Short Case Series</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20J.%20Mathew">J. J. Mathew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pulmonary tuberculosis is highly prevalent in the Indian subcontinent. Most cases of pulmonary tuberculosis are diagnosed with sputum examinations and the vast majority of these are undertaken by the government run establishments. However, mycobacterial cultures are not routinely done, unless drug resistance is detected based on clinical response. Modern diagnostic tests like bronchoscopy and Genexpert are not routinely employed in the government institutions for the diagnosis of pulmonary tuberculosis, but have been accepted widely by good private institutions. The utility of these investigations in the private sector is not yet well recognized. This retrospective study aims to assess the usefulness of bronchoscopy and Genexpert in the diagnosis of pulmonary tuberculosis in quaternary care private hospital in India. 30 patients with respiratory symptoms raising the possibility of tuberculosis based on clinical and radiological features, but without any significant sputum production, were subject to bronchoscopy and BAL samples taken for microbiological studies, including Genexpert. 6 out of the 30 patients were found to be Genexpert positive and none of them showed Rifampicin resistance. All the 6 cases had upper zone predominant disease. One of the 6 cases of tuberculosis had another co-existent bacterial infection according to the routine culture studies. 6 other cases were proven to be due to other bacterial infections alone, 2 had a malignant diagnosis and the remaining cases were thought to be non-infective pathologies. The Genexpert results were made available within 48 hours in the 6 positive cases. All of them were commenced on standard anti-tuberculous regimen with excellent clinical response. The other infective cases were also managed successfully based on the drug susceptibilities. The study has shown the usefulness of these investigations as early intervention enabled diagnosis facilitating treatment and prevention of any clinical deterioration. The study lends support to early bronchoscopy and Genexpert testing in suspected cases of pulmonary tuberculosis without significant sputum production, in a high prevalence country which normally relies on sputum examination for the diagnosis of pulmonary tuberculosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pulmonary" title="pulmonary">pulmonary</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bronchoscopy" title=" bronchoscopy"> bronchoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=genexpert" title=" genexpert"> genexpert</a> </p> <a href="https://publications.waset.org/abstracts/47668/bronchoscopy-and-genexpert-in-the-diagnosis-of-pulmonary-tuberculosis-in-the-indian-private-health-sector-a-short-case-series" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47668.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">245</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">5166</span> Adequacy of Second-Generation Laryngeal Mask Airway during Prolonged Abdominal Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sukhee%20Park">Sukhee Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaab%20Soo%20Kim"> Gaab Soo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: We aimed to evaluate the adequacy of second-generation laryngeal mask airway use during prolonged abdominal surgery in respect of ventilation, oxygenation, postoperative pulmonary complications (PPC), and postoperative non-pulmonary complications on living donor kidney transplant (LDKT) surgery. Methods: In total, 257 recipients who underwent LDKT using either laryngeal mask airway-ProSeal (LMA-P) or endotracheal tube (ETT) were retrospectively analyzed. Arterial partial pressure of carbon dioxide (PaCO2 and ratio of arterial partial pressure of oxygen to fractional inspired oxygen (PFR) during surgery were compared between two groups. In addition, PPC including pulmonary aspiration and postoperative non-pulmonary complications including nausea, vomiting, hoarseness, vocal cord palsy, delirium, and atrial fibrillation were also compared. Results: PaCO2 and PFR during surgery were not significantly different between the two groups. PPC was also not significantly different between the two groups. Interestingly, the incidence of delirium was significantly lower in the LMA-P group than the ETT group (3.0% vs. 10.3%, P = 0.029). Conclusions: During prolonged abdominal surgery such as LDKT, second-generation laryngeal mask airway offers adequate ventilation and oxygenation and can be considered a suitable alternative to ETT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laryngeal%20mask%20airway" title="laryngeal mask airway">laryngeal mask airway</a>, <a href="https://publications.waset.org/abstracts/search?q=prolonged%20abdominal%20surgery" title=" prolonged abdominal surgery"> prolonged abdominal surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=kidney%20transplantation" title=" kidney transplantation"> kidney transplantation</a>, <a href="https://publications.waset.org/abstracts/search?q=postoperative%20pulmonary%20complication" title=" postoperative pulmonary complication"> postoperative pulmonary complication</a> </p> <a href="https://publications.waset.org/abstracts/100086/adequacy-of-second-generation-laryngeal-mask-airway-during-prolonged-abdominal-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100086.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5165</span> Developing HRCT Criterion to Predict the Risk of Pulmonary Tuberculosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vandna%20Raghuvanshi">Vandna Raghuvanshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikrant%20Thakur"> Vikrant Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Anupam%20Jhobta"> Anupam Jhobta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To design HRCT criterion to forecast the threat of pulmonary tuberculosis. Material and methods: This was a prospective study of 69 patients with clinical suspicion of pulmonary tuberculosis. We studied their medical characteristics, numerous separate HRCT-results, and a combination of HRCT findings to foresee the danger for PTB by utilizing univariate and multivariate investigation. Temporary HRCT diagnostic criteria were planned in view of these outcomes to find out the risk of PTB and tested these criteria on our patients. Results: The results of HRCT chest were analyzed, and Rank was given from 1 to 4 according to the HRCT chest findings. Sensitivity, specificity, positive predictive value, and negative predictive value were calculated. Rank 1: Highly suspected PTB. Rank 2: Probable PTB Rank 3: Nonspecific or difficult to differentiate from other diseases Rank 4: Other suspected diseases • Rank 1 (Highly suspected TB) was present in 22 (31.9%) patients, all of them finally diagnosed to have pulmonary tuberculosis. The sensitivity, specificity, and negative likelihood ratio for RANK 1 on HRCT chest was 53.6%, 100%, and 0.43, respectively. • Rank 2 (Probable TB) was present in 13 patients, out of which 12 were tubercular, and 1 was non-tubercular. • The sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio of the combination of Rank 1 and Rank 2 was 82.9%, 96.4%, 23.22, and 0.18, respectively. • Rank 3 (Non-specific TB) was present in 25 patients, and out of these, 7 were tubercular, and 18 were non-tubercular. • When all these 3 ranks were considered together, the sensitivity approached 100% however, the specificity reduced to 35.7%. The positive likelihood ratio and negative likelihood ratio were 1.56 and 0, respectively. • Rank 4 (Other specific findings) was given to 9 patients, and all of these were non-tubercular. Conclusion: HRCT is useful in selecting individuals with greater chances of pulmonary tuberculosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pulmonary" title="pulmonary">pulmonary</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=multivariate" title=" multivariate"> multivariate</a>, <a href="https://publications.waset.org/abstracts/search?q=HRCT" title=" HRCT"> HRCT</a> </p> <a href="https://publications.waset.org/abstracts/142334/developing-hrct-criterion-to-predict-the-risk-of-pulmonary-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142334.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">172</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">5164</span> A Prospective Randomised Observational Study of Obstructed Total Anamalous Pulmonary Venous Connection (TAPVC) Repair Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanjeev%20Singh">Sanjeev Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Obstructed total anomalous pulmonary venous connection (OTAPVC) typically presents with severe cardiovascular decompensation and requires urgent surgical management. Pulmonary arterial hypertension (PAH) is a major risk factor affecting mortality. Perioperative management focuses on providing inotropic support and managing potential pulmonary hypertensive episodes. The aim of this study was to determine the outcome of patients with high pulmonary arterial pressure (PAP) with milrinone alone and a combination of milrinone and inhaled nitric oxide (INO). Material and Methods: After the approval of the ethical committee, this single-center prospective randomized and observational study was conducted over a period of two years among eighty-six patients with obstructed TAPVC repair with severe PAH. Group-I patients received milrinone, and Group-II patients received both milrinone (after aortic cross-clamp removal) and INO during the post-operative period at the cardiac care unit (CCU). Clinical outcomes such as ventilation time, length of stay (LOS) in the CCU, LOS in the hospital, complications, and hospital mortality were compared between the two groups. Result: The average ventilation time, LOS in CCU, and LOS in hospital for group I were 96.82 ± 19.46 hours, 10.91 ± 7.53 days, and 14.46 ± 7.58 days, respectively, and for group II, it was 85.14 ± 15.79 hours, 7.28 ± 3.68 days, and 10.21 ± 3.14 days, respectively, which was statistically significantly lower for group II. Reintubation, RV dysfunction, and hospital mortality were 16.3%, 37.2%, and 6.9% in group I, and 4.8%, 14.6%, and 2.4% in group II, respectively. The P value for each variable was significant < 0.05 (except mortality). Conclusion: Preoperative obstruction is a risk factor for postoperative obstruction, as 235 patients with obstructed TAPVC had severe PAH (39.98%) in this study. Management of severe PAH with a combination of milrinone and INO had a better outcome than milrinone alone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inhaled%20nitric%20oxide" title="inhaled nitric oxide">inhaled nitric oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=milrinone" title=" milrinone"> milrinone</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20artery%20hypertension" title=" pulmonary artery hypertension"> pulmonary artery hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20anomalous%20pulmonary%20venous%20connection" title=" total anomalous pulmonary venous connection"> total anomalous pulmonary venous connection</a> </p> <a href="https://publications.waset.org/abstracts/191851/a-prospective-randomised-observational-study-of-obstructed-total-anamalous-pulmonary-venous-connection-tapvc-repair-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191851.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">21</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">5163</span> Clara Cell Secretory Protein 16 Serum Level Decreases in Patients with Non-Smoking-Related Chronic Obstructive Pulmonary Diseases (COPD) </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lian%20Wu">Lian Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mervyn%20Merrilees"> Mervyn Merrilees</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chronic Obstructive Pulmonary Disease (COPD) is a worldwide problem, characterized by irreversible and progressive airflow obstruction. In New Zealand, it is currently the 4th commonest cause of death and exacerbations of COPD are a frequent cause of admission to hospital. Serum levels of Clara cell secretory protein-16 (CC-16) are believed to represent Clara cell toxicity. More recently, CC-16 has been found to be associated with smoker COPD. It is produced almost exclusively by non-ciliated Clara cells in the airways, and its primary function is to protect the lungs against oxidative stress and carcinogenesis. After acute exposure to cigarette smoke, serum levels of CC-16 become elevated. CC16 is a potent natural immune-suppressor and anti-inflammatory agent. In vitro, CC16 inhibits both monocyte and polymorphonuclear neutrophils chemotaxis and phagocytosis. CC16 also inhibits fibroblast chemotaxis. However, the role of CC-16 in non-smoking related COPD is still not clear. In this study, we investigated serum CC-16 levels in non-smoking related COPD. Methods: We compared non-smoker patients with COPD (FEV1<60% of predicted, FEV1/FVC <0.7, n=100) and individuals with normal lung function FEV1≥ 80% of predicted and FEV1/FVC≥ 0.7, n=80). All subjects had no smoking history. CC-16 was measured by ELISA. Results and conclusion: Serum CC-16 levels are reduced in individuals with non-smoking related COPD, and there is a weak correlation with disease severity in non-smoking related COPD group compared to non-smoker controls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COPD" title="COPD">COPD</a>, <a href="https://publications.waset.org/abstracts/search?q=CC-16" title=" CC-16"> CC-16</a>, <a href="https://publications.waset.org/abstracts/search?q=ELISA" title=" ELISA"> ELISA</a>, <a href="https://publications.waset.org/abstracts/search?q=non-smoking-related%20COPD" title=" non-smoking-related COPD"> non-smoking-related COPD</a> </p> <a href="https://publications.waset.org/abstracts/49844/clara-cell-secretory-protein-16-serum-level-decreases-in-patients-with-non-smoking-related-chronic-obstructive-pulmonary-diseases-copd" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49844.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">380</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">5162</span> Directly Observed Treatment Short-Course (DOTS) for TB Control Program: A Ten Years Experience </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Solomon%20Sisay">Solomon Sisay</a>, <a href="https://publications.waset.org/abstracts/search?q=Belete%20Mengistu"> Belete Mengistu</a>, <a href="https://publications.waset.org/abstracts/search?q=Woldargay%20Erku"> Woldargay Erku</a>, <a href="https://publications.waset.org/abstracts/search?q=Desalegne%20Woldeyohannes"> Desalegne Woldeyohannes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Tuberculosis is still the leading cause of illness in the world which accounted for 2.5% of the global burden of disease, and 25% of all avoidable deaths in developing countries. Objectives: The aim of study was to assess impact of DOTS strategy on tuberculosis case finding and treatment outcome in Gambella Regional State, Ethiopia from 2003 up to 2012 and from 2002 up to 2011, respectively. Methods: Health facility-based retrospective study was conducted. Data were collected and reported in quarterly basis using WHO reporting format for TB case finding and treatment outcome from all DOTS implementing health facilities in all zones of the region to Federal Ministry of Health. Results: A total of 10024 all form of TB cases had been registered between the periods from 2003 up to 2012. Of them, 4100 (40.9%) were smear-positive pulmonary TB, 3164 (31.6%) were smear-negative pulmonary TB and 2760 (27.5%) had extra-pulmonary TB. Case detection rate of smear-positive pulmonary TB had increased from 31.7% to 46.5% from the total TB cases and treatment success rate increased from 13% to 92% with average mean value of being 40.9% (SD= 0.1) and 55.7% (SD=0.28), respectively for the specified year periods. Moreover, the average values of treatment defaulter and treatment failure rates were 4.2% and 0.3%, respectively. Conclusion: It is possible to achieve the recommended WHO target which is 70% of CDR for smear-positive pulmonary TB, and 85% of TSR as it was already been fulfilled the targets for treatments more than 85% from 2009 up to 2011 in the region. However, it requires strong efforts to enhance case detection rate of 40.9% for smear-positive pulmonary TB through implementing alternative case finding strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gambella%20Region" title="Gambella Region">Gambella Region</a>, <a href="https://publications.waset.org/abstracts/search?q=case%20detection%20rate" title=" case detection rate"> case detection rate</a>, <a href="https://publications.waset.org/abstracts/search?q=directly%20observed%20treatment%20short-course" title=" directly observed treatment short-course"> directly observed treatment short-course</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment%20success%20rate" title=" treatment success rate"> treatment success rate</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis "> tuberculosis </a> </p> <a href="https://publications.waset.org/abstracts/2519/directly-observed-treatment-short-course-dots-for-tb-control-program-a-ten-years-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2519.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">344</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">5161</span> Reduced Lung Volume: A Possible Cause of Stuttering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shantanu%20Arya">Shantanu Arya</a>, <a href="https://publications.waset.org/abstracts/search?q=Sachin%20Sakhuja"> Sachin Sakhuja</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunjan%20Mehta"> Gunjan Mehta</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Munjal"> Sanjay Munjal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stuttering may be defined as a speech disorder affecting the fluency domain of speech and characterized by covert features like word substitution, omittance and circumlocution and overt features like prolongation of sound, syllables and blocks etc. Many etiologies have been postulated to explain stuttering based on various experiments and research. Moreover, Breathlessness has also been reported by many individuals with stuttering for which breathing exercises are generally advised. However, no studies reporting objective evaluation of the pulmonary capacity and further objective assessment of the efficacy of breathing exercises have been conducted. Pulmonary Function Test which evaluates parameters like Forced Vital Capacity, Peak Expiratory Flow Rate, Forced expiratory flow Rate can be used to study the pulmonary behavior of individuals with stuttering. The study aimed: a) To identify speech motor & physiologic behaviours associated with stuttering by administering PFT. b) To recognize possible reasons for an association between speech motor behaviour & stuttering severity. In this regard, PFT tests were administered on individuals who reported signs and symptoms of stuttering and showed abnormal scores on Stuttering Severity Index. Parameters like Forced Vital Capacity, Forced Expiratory Volume, Peak Expiratory Flow Rate (L/min), Forced Expiratory Flow Rate (L/min) were evaluated and correlated with scores of Stuttering Severity Index. Results showed significant decrease in the parameters (lower than normal scores) in individuals with established stuttering. Strong correlation was also found between degree of stuttering and the degree of decrease in the pulmonary volumes. Thus, it is evident that fluent speech requires strong support of lung pressure and requisite volumes. Further research in demonstrating the efficacy of abdominal breathing exercises in this regard is needed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forced%20expiratory%20flow%20rate" title="forced expiratory flow rate">forced expiratory flow rate</a>, <a href="https://publications.waset.org/abstracts/search?q=forced%20expiratory%20volume" title=" forced expiratory volume"> forced expiratory volume</a>, <a href="https://publications.waset.org/abstracts/search?q=forced%20vital%20capacity" title=" forced vital capacity"> forced vital capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20expiratory%20flow%20rate" title=" peak expiratory flow rate"> peak expiratory flow rate</a>, <a href="https://publications.waset.org/abstracts/search?q=stuttering" title=" stuttering"> stuttering</a> </p> <a href="https://publications.waset.org/abstracts/52239/reduced-lung-volume-a-possible-cause-of-stuttering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52239.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">275</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">5160</span> The out of Proportion - Pulmonary Hypertension in Indians with Chronic Lung Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20P.%20Chintan">S.

As recent as 15 years ago, a patient diagnosed with PH was given an average survival rate of 2.8 years. Recent advances in treatment options have allowed patients to improve quality o and quantity of life. Initial screening for PH is through echocardiography with final diagnosis confirmed through right heart catheterization. PH is now considered to have five major classifications with subgroups among each. The mild to moderate PH is common in chronic lung diseases like Chronic obstructive pulmonary diseases and Interstitial lung disease. But very severe PH is noted in few cases. In COPD patients, PH is associated with an increased risk of severe exacerbations and a reduced life expectancy. Similarly, in patients with ILD, the presence of PH correlates with a poor prognosis. Early diagnosis is essential to slow disease progression. We report here five cases of severe PH (Out of Proportion) of which four cases were of COPD and another one of IPF (UIP pattern). There echocardiography showed gross RA/RV dilatation, interventricular septum bulging to the left and mPAP of more than 100 mmHg in all the five cases. These patients were put on LTOT, pulmonary rehabilitation, combination pharmacotherapy of vasodilators and diuretics in continuation to the treatment of underlying disease. As these patients have grave prognosis close monitoring and follow up is required. Physicians associated with respiratory care and treating chronic lung disease should have knowledge in the diagnosis and management of patients with PH. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COPD" title="COPD">COPD</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20hypertension" title=" pulmonary hypertension"> pulmonary hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20lung%20disease" title=" chronic lung disease"> chronic lung disease</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a> </p> <a href="https://publications.waset.org/abstracts/3773/the-out-of-proportion-pulmonary-hypertension-in-indians-with-chronic-lung-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3773.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">357</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">5159</span> Pulmonary Complication of Chronic Liver Disease and the Challenges Identifying and Managing Three Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aidan%20Ryan">Aidan Ryan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nahima%20Miah"> Nahima Miah</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahaj%20Kaur"> Sahaj Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Imogen%20Sutherland"> Imogen Sutherland</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Saleh"> Mohamed Saleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pulmonary symptoms are a common presentation to the emergency department. Due to a lack of understanding of the underlying pathophysiology, chronic liver disease is not often considered a cause of dyspnea. We present three patients who were admitted with significant respiratory distress secondary to hepatopulmonary syndrome, portopulmonary hypertension, and hepatic hydrothorax. The first is a 27-year-old male with a 6-month history of progressive dyspnea. The patient developed a severe type 1 respiratory failure with a PaO₂ of 6.3kPa and was escalated to critical care, where he was managed with non-invasive ventilation to maintain oxygen saturation. He had an agitated saline contrast echocardiogram, which showed the presence of a possible shunt. A CT angiogram revealed significant liver cirrhosis, portal hypertension, and large para esophageal varices. Ultrasound of the abdomen showed coarse liver echo patter and enlarged spleen. Along with these imaging findings, his biochemistry demonstrated impaired synthetic liver function with an elevated international normalized ratio (INR) of 1.4 and hypoalbuminaemia of 28g/L. The patient was then transferred to a tertiary center for further management. Further investigations confirmed a shunt of 56%, and liver biopsy confirmed cirrhosis suggestive of alpha-1-antitripsyin deficiency. The findings were consistent with a diagnosis of hepatopulmonary syndrome, and the patient is awaiting a liver transplant. The second patient is a 56-year-old male with a 12-month history of worsening dyspnoea, jaundice, confusion. His medical history included liver cirrhosis, portal hypertension, and grade 1 oesophageal varices secondary to significant alcohol excess. On admission, he developed a type 1 respiratory failure with PaO₂ of 6.8kPa requiring 10L of oxygen. CT pulmonary angiogram was negative for pulmonary embolism but showed evidence of chronic pulmonary hypertension, liver cirrhosis, and portal hypertension. An echocardiogram revealed a grossly dilated right heart with reduced function, pulmonary and tricuspid regurgitation, and pulmonary artery pressures estimated at 78mmHg. His biochemical markers showed impaired synthetic liver function with an INR of 3.2, albumin of 29g/L, along with raised bilirubin of 148mg/dL. During his long admission, he was managed with diuretics with little improvement. After three weeks, he was diagnosed with portopulmonary hypertension and was commenced on terlipressin. This resulted in successfully weaning off oxygen, and he was discharged home. The third patient is a 61-year-old male who presented to the local ambulatory care unit for therapeutic paracentesis on a background of decompensated liver cirrhosis. On presenting, he complained of a 2-day history of worsening dyspnoea and a productive cough. Chest x-ray showed a large pleural effusion, increasing in size over the previous eight months, and his abdomen was visibly distended with ascitic fluid. Unfortunately, the patient deteriorated, developing a larger effusion along with an increase in oxygen demand, and passed away. Without underlying cardiorespiratory disease, in the presence of a persistent pleural effusion with underlying decompensated cirrhosis, he was diagnosed with hepatic hydrothorax. While each presented with dyspnoea, the cause and underlying pathophysiology differ significantly from case to case. By describing these complications, we hope to improve awareness and aid prompt and accurate diagnosis, vital for improving outcomes. <p class="card-text"><strong>Keywords:</strong> <a
