Hereditary spherocytosis (HS), a familial defect involving red blood cell (RBC) membrane proteins, is associated with reduced deformability, increased fragility, and progressive destruction of spherical cells. The present study focuses on three subjects of a family showing a history of repeated episodes of lethargy and pallor of unknown etiology. All patients displayed reticulocytosis and spherocytosis and one of them had anemia and splenomegaly. The patients underwent screening tests to rule in/out possible underlying disorders, and deficiency/dysfunction of RBC membrane proteins was suspected. Definitive diagnosis can be made on the basis of membrane protein analysis by quantitative sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Interestingly, all patients showed marked decrease in the protein 4.2 expression and therefore, HS was confirmed. This case report highlights the simultaneous occurrence of protein 4.2-dependent "typical" and "atypical" HS in a family and serves as a reminder to clinicians to consider RBC membrane disorders in patients presenting with suspicious and unexplained clinical signs. find more © 2020 The Author(s).

The high prevalence of psychiatric disorders and their increasing burden are noteworthy. The aim of this study is to investigate the effectiveness of community-based preventive interventions for depression and anxiety in women. METHODS We systematically searched for articles published up to the beginning of 2018, which addressed community-based preventive interventions for depression and anxiety in women. The studies were searched in PubMed, Scopus, Cochrane Library, Web of Science, PsycInfo, IranMedex, SID and EMBASE electronic databases. Articles that complied with our inclusion criteria (preventive interventions involving healthy adult women aged 18 to 65 years) were reviewed. Quality assessment of the articles was performed using standard tools. We extracted the required data and reported the results in a narrative form. RESULTS Twenty-three articles were identified and entered into the final review. Depression and anxiety symptoms were decreased in more than 70% of interventions. Cognitive behavioral therapy (CBT) and exercise were the most effective interventions. In addition, computer and internet-based programs had positive outcomes in both categories of depression and anxiety. CONCLUSION Community-based preventive programs for depression and anxiety in women had promising and positive results. CBT and exercise were the most effortless, yet the most effective interventions to apply. Computer and internet-based programs had the benefit of covering many people simultaneously. These interventions are cost-effective and feasible among Iranian women. © 2020 The Author(s). link2 This is an open-access article distributed under the terms of the Creative Commons Attribution License (http//creativecommons.org/licenses/by/4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.BACKGROUND Hepatitis B infection is the major risk factor for liver cancer in Iran. There is no comprehensive population-based study on the prevalence of hepatitis B by regional distribution. Moreover, systematic reviews of hepatitis B prevalence lack knowledge of some regions. We aimed to estimate the prevalence of hepatitis B and its temporal trends over 17 years by sex, age and geographical distribution. METHODS We used the Iranian Blood Donors data in addition to systematic reviews on population-based studies at national and provincial levels and statistical methods (A two-stage spatio-temporal model and crosswalk approach) to address the missing points of hepatitis B prevalence among the general population. The direct age-standardized approach was applied using Iran's national population in 2016. RESULTS At national level, age-standardized hepatitis B prevalence in Iran decreased from 3.02% (95% uncertainty interval; 2.26 to 3.96) in 2000 to 1.09% (95% uncertainty interval; 0.85 to 1.37) in 2016, with a rg/licenses/by/4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.BACKGROUND With the growing rate of tumors, cancer has become one of the most important health concerns in Iran. The urgency with which Iranian researchers and health professionals address this challenge leads to a load of scientific materials. link3 METHODS To reveal gaps in produced knowledge and suggest future research directions, applying well-validated scientometric tools, we assessed the trends of Iranian published scientific articles and citations in the field of oncology. The inclusion criteria consisted of all oncology-related articles that were data-based, and peer-reviewed; with at least an abstract published in English; and authored by at least one researcher affiliated with Iranian institutions. RESULTS Amongst 5063525 oncology research records indexed in at least one of PubMed, Scopus, or Web of Science Core Collection (WoS) from the start to February 2019, Iranian researches accounted for about 24867 (0.49%). Published articles on all cancers by Iranian researchers had a sharp continuously ascending trend, with the same pattern for citations received. Some important topics such as complementary and alternative medicine (CAM) therapies have been missing and some such as diagnostic and pharmaceutical innovations have been less investigated. The most collaborative country was the United States, while no close collaboration was observed with China that was introduced as the most productive country in the field of oncology over the past decades. CONCLUSION Despite the progressive trend in most oncology fields, some significant practical topics are still missing. Systematic reviews of produced theoretical innovations and translating them to functional knowledge can be of importance to fulfill the mentioned gaps. © 2020 The Author(s).

This study aimed to test the moderating effect of social loneliness in the relationship between worry and anger rumination, and CVD severity. METHODS A total of 327 patients with CVD (138 women, 189 men) participated in this study. The Penn State Worry Questionnaire (PSWQ), Anger Rumination Scale (ARS), Social Loneliness Scale (SLS), and Gensini score as an indicator of CVD severity were used to collect data. Data were analyzed using Pearson correlation and stepwise regression. RESULTS The results of this study showed a significant positive correlation between worry (54.44 ± 12.31, r = 0.59, P 0.05). CONCLUSION Based on the findings of this research, it can be concluded that along with biological factors, attention to the role of psychological factors of worry, anger rumination, and loneliness in preventive and therapeutic interventions related to CVD is a special necessity. © 2020 The Author(s).

The purpose of this study was to provide a better understanding of age and PTC using the Surveillance, Epidemiology, and End Results (SEER) Program. METHODS The study derived patients' information from the SEER Program (2010-2015). Chi-square or Fisher exact tests, and Kaplan-Meier method were used to analyze survival. Prognostic factors associated with survival were analyzed by Cox multivariate regression. RESULTS A total of 1738 records were included from SEER, with 1079 PTC in the age group less then 55 years, and 659 PTC in the age group ≥55 years. The 5-year survival rate was 94% and the overall survival (OS) curve in different age groups indicated that patients younger than 55yr have a longer survival time (P less then 0.05). In multivariate Cox regression, age, M stage and surgery treatment were independent risk factors (P less then 0.05). Regarding PTC-specific survival, age and surgery treatment were the two main independent prognostic factors in multivariate regression. However, AJCC and M stage were not in the disease specific survival. CONCLUSION Age is a prognostic factor in OS and PCT specific survival. AJCC I stage and surgery treatment are also significant in predicting prognosis. © 2020 The Author(s).

The aim of this study was to evaluate the prevalence of M. abscessus in patients with non-tuberculous mycobacteria. METHODS This descriptive study was performed on 18,083 samples isolated from patients with non-tuberculous mycobacteria during 2011-2017 at the Mycobacteriology Research Center (MRC), Tehran, Iran. To identify the Mycobacterium species, a 439 bp fragment of the IS6110 gene was first amplified using primers TB1 and TB2. Samples with a negative polymerase chain reaction (PCR) result were analyzed to investigate non-tuberculosis mycobacteria (NTM), especially M. abscessus using the RFLP method. RESULTS Of the 18,083 samples, 5513 (30.49%, 95% CI, 12.95) strains of Complex Tuberculosis and 236 (1.31%, 95% CI, 1.84) strains of NTM were identified. The mean age of the patients with NTM was 18 years, and most of them were male. The most commonly identified species in this study were M. abscessus type Ι 32 (13.56%, 95% CI, 18.36) and M. abscessus type II 13 (5.51%, 95%CI, 20.04). CONCLUSION In this study, we observed a high prevalence of Mycobacterium abscessus type 1 in patients. As the treatment protocol for non-TB mycobacteria is different from M. abscessus complex, the diagnosis of these species as soon as possible will be significant for physicians. © 2020 The Author(s).
