The prevalence of hepatitis C and hepatitis B in lesbian, gay, bisexual and transgender populations: a systematic review and meta-analysis

Objectives

This study aimed to systematically review the literature on the prevalence of hepatitis C virus (HCV) and hepatitis B virus (HBV) infections in transgender and LGBT people and determine their pooled estimates worldwide.

Methods

Databases (PubMed, Scopus, Web of Science, Embase, Ovid, Cochrane, PsycInfo) were searched from April 2000 to July 2021. The analyses were executed using the random-effects model in Stata 16.

Results

Ten studies, including eight studies on four transgender people and two studies on 2150 LGBTs, were included. The pooled prevalence of HCV and HBV in all transgender populations globally were 9% (95% CI 3–15%) and 11% (95% CI 2–20%), respectively. The corresponding prevalence in male-to-female transgender people were estimated as 5% (95% CI 1–9%) and 6% (95% CI 3–10%), respectively. These estimates in American transgenders were 10% (95% CI 5–25%) and 16% (95% CI 8–23%), respectively.

Conclusion

This study was identified the overall prevalence of HBV and HCV infections in transgender people, which were higher than those in the general population.

Pleural Effusion in a Child With COVID-19: A Case Report

The coronavirus disease 2019 (COVID-19) outbreak started in December 2019. The disease can manifest in various respiratory and non-respiratory symptoms and clinical findings. The signs and symptoms of this disease in children are not entirely known yet. Ground-glass opacity and pleural effusion in the chest computed tomography scan have been reported in infected patients. The pleural effusion has been reported in a few cases. The present case report describes a pediatric patient with the chief complaints of fever, diarrhea, and vomiting who presented to an emergency department with a differential diagnosis of a gastrointestinal infection. However, he was diagnosed with COVID-19, which was complicated by respiratory distress and pleural effusion.

Griscelli Syndrome in a seven years old girl

In this study, a case of Griscelli Syndrome (GS) in a 7 years old girl was reported. The patient initially presented with fever and pancytopenia in laboratory results; after ruling out the malignancies, she went under treatment with the diagnosis of infectious disease and was discharged after two weeks. Nevertheless, ten days after discharge, she developed new symptoms. Due to patient symptoms and general appearance, microscopic analysis of her hair shaft was done, and the abnormal distribution of pigments in the shaft was observed, indicating GS.

Evaluating Vertical Transmission of COVID-19 from Mothers to Neonates: An Iranian Case Series of 8 Patients

The coronavirus epidemic first broke out in China in 2019 and spread around the world. Not only the signs, symptoms, and outcomes of the coronavirus in neonates, but also its vertical transmission risks are still unknown. This case series presents eight neonates born to mothers with COVID-19 and two neonates with this infection.

The national trend of the gastric cancer burden in Iran from 1990 to 2017

INTRODUCTION

Gastric cancer (GC), the leading cause of cancer mortality, is the third most common cancer in Iran. To our knowledge, there have been few accurate estimates on the burden of GC in Iran. Therefore, as part of the Global Burden of Diseases Study 2017 (GBD 2017), we aimed to study and illustrate the burden of GC and to compare rates by sex and age groups at the national level in Iran from 1990 to 2017.

METHODS

We extracted data related to the 1990-2017 period from the GBD study. To report the burden of GC, we used disability adjusted life years (DALYs), mortality, incidence, and prevalence rates in different sex and age groups in Iran during the 1990-2017 period. Decomposition analysis was also performed to evaluate the roots change in incident cases.

RESULTS

At a national level, the age-standardized prevalence rate (ASPR), age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR), and age-standardized DALYs rate (ASDR) in 2017 were 22.9 (95% uncertainty interval [UI]: 22.1-23.9), 14.6 (14.1-15.2), 14.9 (14.4-15.4), and 296.8 (286.3-308.7) per 100,000 population, respectively. Over the 1990-2017 period, the average annual percent changes in all of the studied age-standardized rates were negative. Moreover, the male to female sex ratios of all estimates were greater than one. The incidence rate, prevalence rate, and mortality rate slowly began to increase at the age of 50 and reached its highest level among people aged 80 years and over.

CONCLUSION

The GC age-standardized rates revealed a downward trend from 1990 to 2017. The current study provides comprehensive knowledge about the GC burden in Iran. Therefore, it can help the appropriate allocation of resources for GC to expand preventive programs by reducing exposure to risk factors and Helicobacter pylori infection and by recommending increased consumption of fruits and vegetables. Also, expanding GC screening programs with laboratory tests or endoscopy can be an important step towards the reduction of the GC burden.
