Background And Aims: The kidney transplant patients who receive immunosuppressive and specific medication may lead to different mortality risk factors between kidney transplant patients with COVID-19 and the general population. We aimed to provide a model predictor and a risk analysis of mortality in kidney transplant COVID-19 positive patients.

Methods: We performed our search using PubMed, MEDLINE, Web of Science, Scopus, and Google Scholar to identify English articles published from the beginning of December 2019 through August 2020.

Administration of Silver Nanoparticles in Diabetes Mellitus: A Systematic Review and Meta-analysis on Animal Studies.

Biological features of silver nanoparticles in rising the insulin level of diabetic animal models were considered in recent years, which resulted in decreasing hyperglycemia condition. We reviewed the published literature to investigate the possible role of silver nanoparticles (Ag-NPs) throughout the treatment of diabetes mellitus in animal studies. In this systematic review and meta-analysis, we performed a search throughout the English literature of electronic databases, including Scopus, PubMed, and ISI Web of Science, up to the date of May 22, 2020.

The effects of melatonin therapy on the treatment of patients with Non-alcoholic steatohepatitis: A systematic review and Meta-analysis on clinical trial studies.

Melatonin has shown promising effects in controlling the progress of non-alcoholic fatty liver disease (NAFLD), introducing it as a possible candidate for NAFLD treatment. In this context, the current study is aimed to evaluate melatonin's effect on the plasma levels of Gamma-glutamyl transpeptidase, cholesterol, triglyceride, and liver aminotransferases in NAFLD patients. NAFLD and melatonin, as well as their related terms, were searched in electronic databases, until May 1st, 2020.

Secular trends of ischaemic heart disease, stroke, and dementia in high-income countries from 1990 to 2017: the Global Burden of Disease Study 2017.

Background: We assessed secular trends in the burden of ischaemic heart disease (IHD), stroke, and dementia in the Organization for Economic Co-operation and Development (OECD) countries.

Methods: Using the Global Burden of Disease (GBD) Study 2017, we compared sex-specific and age-standardized rates of disability-adjusted life years (DALY); mortality, incidence, and prevalence of IHD and stroke; and dementia per 100,000 people, in the world, OECD countries, and Canada.

Results: From 1990 to 2017, the crude incidence number of IHD, stroke, and dementia increased 52%, 76%, and 113%, respectively.

Opium as a carcinogen: A systematic review and meta-analysis.

Background: Opium and its pyrolysates have been investigated as potential carcinogenic material through several studies in different body systems; however, the results were controversial and no consensus was achieved with this regard. Thus, we aimed to systematically review and meta-analyze all existed evidence regarding association between opium consumption and cancer.

Methods: Four major electronic databases including ISI Web of Science, PubMed, Scopus, and Embase along with Magiran and SID were searched thoroughly for all published articles from inception up to September 25, 2020.

Cardiac Complications in COVID-19: A Systematic Review and Meta-analysis.

Background: The newly emerged coronavirus disease 2019 (COVID-19) seems to involve different organs, including the cardiovascular system. We systematically reviewed COVID-19 cardiac complications and calculated their pooled incidences. Secondarily, we compared the cardiac troponin I (cTnI) level between the surviving and expired patients.

Chest CT findings of coronavirus disease 2019 (COVID-19): A comprehensive meta-analysis of 9907 confirmed patients.

Objectives: We performed a systematic review and meta-analysis of the prevalence of chest CT findings in patients with confirmed COVID-19 infection.

Methods: Systematic review of the literature was performed using PubMed, Scopus, Embase, and Google Scholar to retrieve original studies on chest CT findings of patients with confirmed COVID-19, available up to 10 May 2020. Data on frequency and distribution of chest CT findings were extracted from eligible studies, pooled and meta-analyzed using random-effects model to calculate the prevalence of chest CT findings.

Evaluating the Prevalence of PTSD among Children and Adolescents after Earthquakes and Floods: a Systematic Review and Meta-Analysis.

Our study systematically reviews articles about the prevalence of Post-traumatic Stress Disorder (PTSD) among children and adolescents, aiming to evaluate its prevalence after earthquakes and floods.Three databases (PubMed, Scopus, and Web of Science) were searched for articles published from 1981 to 2019 containing information on PTSD prevalence among survivors of earthquakes and floods. Articles with insufficient data on the prevalence of PTSD or without any available full-text were excluded.

Communication barriers between basic scientists and clinicians in regenerative medicine: A qualitative study from Iran.

Rationale, Aims, And Objectives: Cell-based therapeutics are among the latest advances in health care technologies. The rapid evolution of stem cell science in Iran has necessitated the application of scientific achievements in clinical settings. However, various issues hindered their translation, in particular, impediments in the interactions of basic stem cell scientists and clinicians.

"Infection prevention and control idea challenge" contest: a fresh view on medical education and problem solving.

Background: Healthcare-associated infections (HAIs) challenge modern medicine. Considering their high prevalence in Iran, we aimed to provide knowledge on the subject, and to teach about the importance of infection prevention and control (IPC) to a broad audience of pre-graduate healthcare professionals, focusing on education as the cornerstone of IPC.

Main Body: We invited Iranian medical students to present ideas on "how to reduce HAIs.

Association between smoking and non-alcoholic fatty liver disease: A systematic review and meta-analysis.
