Epidemiological profile of hepatitis B virus infection in Iran in the past 25 years; a systematic review and meta-analysis of general population studies

Background: Chronic hepatitis B virus [HBV] infection is one of the most important health problems worldwide with a high rate of morbidity and mortality. It is a major risk factor for cirrhosis and liver cancer. Currently, Iran is located in the intermediate HBV zone; however, recent studies have provided some evidence indicating an epidemiological change in the country. The aim of this study was to estimate the prevalence of HBV in Iran

Methods: A systematic review was conducted to evaluate the studies performed in the past 25 years that have reported the prevalence of HBV infection and its associated factors in the Iranian general population [1990-2014]. Any study assessing and reporting serum Hbs Ag levels was included in this review

Results: After excluding all impertinent studies, 19 eligible studies were included in the analysis. The overall prevalence of HBV was 3% [95% CI 2% to 3%]. Its distribution showed that the prevalence of HBV varies in different provinces from 0.87% to 8.86%. The HBV rate was highest in the Golestan [8.86%] and lowest in the Kurdistan [0.87%] provinces

Conclusion: This study provides some evidence about the prevalence of HBV in Iran. However, the collected data was very heterogenic, even within a single province, which made it hard to estimate a single-point prevalence. High quality studies are needed to find reliable information about HBV prevalence and to decrease the heterogeneity of results in the country

Emotional Labour of Caring for Hematopoietic Stem Cell Transplantation Patients: Iranian Nurses' Experiences

PURPOSE: The purpose of this study was to describe the emotional labour experienced by nurses who care for hematopoietic stem cell transplantation (HSCT) patients in Iran. METHODS: Eighteen nurses participated in semi-structured interviews. The interviews were analyzed using qualitative content analysis methods. RESULTS: Three main categories described the emotional labour involved, namely, emotional intimacy, feeling overwhelmed with the sadness and suffering, and changing self. Nurses had compassion for their patients, contributing to a close nurse-patient relationship. The nurses' emotional labour resulted in their feeling overwhelmed with sadness and suffering. Five subcategories described this emotional toll: (a) witnessing suffering, (b) struggling mentally, (c) hurting emotionally, (d) feeling drained of energy, and (e) escaping grief. Dealing with death and dying on an ongoing basis promoted the nurses' changing self. CONCLUSION: Iranian nurses who care for HSCT patients experience a range of positive and negative emotions. Establishing appropriate support systems for nurses might help mediate the negative aspects of emotional labour. thereby improving nursing work life and ultimately the quality of patient care.
