Sensitivity and specificity for oral fluid assay were measured Sensitivity and specificity of salivary HBs-Ag were 86% and 95%, respectively, and they were 71% and 95%, respectively, for anti-HBc. Conclusion Our results suggest that salivary tests of HBs-Ag and anti-HBc marker could have the potential to replace serological tests for these markers.Dyspnea, shortness of breath, and inability to perform activities of daily living are the main complaints in patients with COVID-19 and physiotherapy has a vital role in managing such symptoms. We present a case treated with pulmonary and neurological physiotherapy, which improved symptoms and quality of life. In this case report, the importance and potential effect of concise physiotherapy on patients with COVID-19 is presented.Background To evaluate the outcome of retrograde endopyelotomy as a minimally invasive option for management of failed open pyeloplasty in children and assess how the duration of post-procedural stenting may affect the endopyelotomy outcome. Methods A total of 15 patients with secondary UPJO (Ureteropelvic junction obstruction) underwent retrograde endopyelotomy. The procedure was done using low-energy monopolar electrocautery hook under direct vision of pediatric ureteroscope and control of fluoroscopy. Double J stent was placed after the operation in all cases. Stent was removed in another session, 8 weeks (Group A, n=7) vs. 12 weeks (Group B, n=8) after endopyelotomy. Patients in both Groups were followed one, six and twelve months after the stent removal, and the anteroposterior renal pelvis diameter (APD), renal cortical thickness (CT) and degree of hydronephrosis (HDN) were recorded using the repeated measure test. P-value less than 0.05 were significant. We analyzed the data using SPSS software, version 20. Results The median interquartile range (IQR) age at time of surgery for group A and B were 24 (62) months and 12 (50) months respectively. Median (IQR) times between previous pyeloplasty and endopyelotomy were 6 (6) months and 12 (8.5) months in groups A and B, respectively. The success rate of endopyelotomy after 12 months was 57.1% in group A and 87.5% in group B. The resolution of HDN was more prominent in the 12 week stenting group compared to the 8 week group during the 12 months follow-up period (p=0.030). The APD and CT in group B compared to group A was improved during follow-up period. Conclusion A higher one-year success rate of retrograde endopyelotomy in terms of improvements in the degree of HDN, APD and CT was observed when the double j stent was remained for 12-weeks rather than 8-weeks. This observation need to be validated in a large cohort study with a long term post procedural follow up.Background One of the efforts that solve complex real-world problems is to use an interdisciplinary approach. However, the contradictions among different disciplines and the absence of a theoretical model add to the difficulty of interdisciplinary activities. When interdisciplinary researchers face a complex problem, they need to integrate several different disciplines. It seems the first step in interdisciplinary activities is to have a theoretical model to understand and examine by what content and method the processes of integrating and crossing the disciplinary boundaries are done. The purpose of this study is to propose a new theoretical model for interdisciplinary development. It also show that a multilayered model can be formed based on the boundaries of scientific disciplines. Methods In this study, the critical review strategy of Carnwell and Daly has been used to synthesize the theoretical model using online databases. The method consists of 5 stages defining the scope of the review, identifying the sources of relevant information, reviewing the literature, writing the review, and applying the literature to the proposed study. Results The results of this study showed for interdisciplinarity, the artificial boundaries of disciplines must be broken. Therefore, we first began to explain the disciplinary boundaries in 13 levels, then, we proposed interdisciplinary development by examining the views of the experts in this field and with the synthesis opinion of researchers of this study on each of the disciplinary boundaries of the multilayered model. Conclusion This model can effectively support interdisciplinary programs and can bring the goals of interdisciplinary programs closer to practical reality.Background Coronavirus disease 2019 (COVID-19) is caused by a new severe acute respiratory syndrome Coronavirus. COVID-19 patients are at risk for acute respiratory distress syndrome and death from respiratory failure. Methods In this study the complete genome of the SARS-CoV-2 reference sequence, geologically isolated types, and Coronavirus related to human diseases were compared by the Molecular Phylogenetic Maximum Likelihood method. The secondary and tertiary structures of the main protease of SARS-CoV were defined as the most similar viruses to SARS-CoV-2, aligned with chimera software. Therefore, considering ineffective antiviral medications used for SARS-CoV and the importance of preventing acute respiratory distress syndrome as the main cause of mortality, 2 strategies were adopted to acquire the most effective drug combination. Results The results of phylogenic analysis showed that SARS-CoV is the most similar virus to SARS-CoV-2. The secondary structure and superimposing of tertiary structure did noor blockers and C21 could be a potential pharmacologic regimen to control and reduce acute respiratory distress syndrome. Moreover, rhACE2 can be recommended as an effective protective antiviral therapy in the treatment of COVID-19 and its complications.The purpose of the Laboratory Response Checklist for Infectious Disease Outbreaks (the Checklist) is to provide public health laboratories and laboratory networks operating at multiple jurisdictional levels with a useful, adaptable tool to help rapidly identify important outbreak response considerations, particularly when investigating a previously unknown infectious disease threat. The Checklist was developed by the National Microbiology Laboratory of Canada in collaboration with provincial/territorial, national and international laboratory experts, including the Canadian Public Health Laboratory Network, and the Global Health Security Action Group Laboratory Network. selleck screening library While the Checklist was initially designed to reflect lessons learned through National Microbiology Laboratory participation in extended national and international outbreak responses (e.g. Zika virus epidemic [2015-2016], Ebola virus epidemic, West Africa [2014-2016]), the importance of optimizing laboratory response coordination has only been underscored by the ongoing challenges presented by the coronavirus disease 2019 (COVID-19) pandemic response requirements.
