The mortality rate of coronavirus disease-19 (COVID-19) has been reported as 1–6% in most studies. The cause of most deaths has been acute pneumonia. Nevertheless, it has been noted that cardiovasc...

Peptic ulcer is a prevalent problem and symptoms include epigastria pain and heartburn. This study aimed at investigating the prevalence and causes of peptic ulcers in Iran using systematic review and meta-analysis. Eleven Iranian papers published from 2002 to 2016 are selected using valid keywords in the SID, Goggle scholar, PubMed and Elsevier databases. Results of studies pooled using random effects model in meta-analysis. The heterogeneity of the sample was checked using Q test and I² index. Total sample size in this study consist of 1335 individuals with peptic ulcer (121 samples per article). The prevalence of peptic ulcers was estimated 34% (95% CI= 0.25 - 0.43). The prevalence of peptic ulcers was 30% and 60% in woman and man respectively. The highest environmental factor (cigarette) has been addressed in 30% (95% CI= 0.23-0.37) of patients. The prevalence of Helicobacter pylori was estimated in 62% (95% CI= 0.49-0.75) of patients. The results of this study show that prevalence of peptic ulcers in Iran (34%) is higher that worldwide rate (6% to 15%). There was an increasing trend in the prevalence of peptic ulcer over a decade from 2002 to 2016.

Context: Diseases and accidents bring about the disorder at someone's job insofar as one is not able to return to her/his previous work. These cases are related to the amount of occurred accidents, type of disease, and one's job. Aim: The aim of this study was to evaluate the factors that affect return to work (RTW) in cancer survivors using a systematic review and meta-analysis design. Methods: This is a systematic review and meta-analysis study. We searched the PubMed, Scopus, SID, Google, Elsevier, Google Scholar and Web of Science databases using following keywords: Return to work, cancer patients, employment status, cancer survivors from 2002 to 2017. The rate of return to work in cancer patients based on age group and risk factors was calculated using subgroup analysis. Data were analyzed using STATA software (version 11.1). Results: The total sample size was 4675 people with a mean of 668 in each study. The frequency of studies in the world consists mainly of five studies (71.5%) from Europe continent (the Netherlands and Denmark) and two studies (28.5%) from Asia continent (Iran and Japan). The overall rate of RTW estimated at 72% (68%-77%). The percentage of RTW in Asia and Europe was 57% (50%-65%) and 52% (43%-60%), respectively. Surgery had the highest percentage of treatment options in patients with cancer with 46% (25%-68%), followed by radiotherapy and chemotherapy with 37% (29%-46%) and 36% (23%-49%), respectively. Breast cancer and gastrointestinal cancer were the most and less common type of cancers with 36% (19%-54%) and 16% (7%-26%), respectively. Conclusion: The overall rate of RTW estimated at 57%. Nonetheless, the faster diagnosis and regular screening could improve the survival rate of cancer patients and the increase of RTW.

Epilepsy is one of the most common diseases in Iran contributing to an array of health problems. In light of this, the aim of the present study is to examine the prevalence of epilepsy in Iran through a systematic review and meta-analysis. A systematic search of several databases including PubMed, scientific information databases, Google, Google scholar, Elsevier and Scopus was conducted in June 2013. Observational studies were considered for inclusion if they were published in Iranian and examined epilepsy prevalence and/or related risk factors. Meta-analysis was conducted using a random effect model with the DerSimonian/Laird method. Heterogeneity was examined using the Breslow- Day test and inconsistency using the I2 statistic. A total of 45 studies were identified from the search strategy. Of these, nine published manuscripts with a total of 7,723 participants were included within the review. The pooled prevalence of epilepsy in Iran was estimated to be around 5% (95% confident interval (CI) 2 to 8). For each region the prevalence of epilepsy in central, northern and eastern Iran were 5% (95%CI 2 to 8), 1% (95%CI -1 to 3) and 4% (95%CI 3 to 11) respectively. The most common risk factors in order of prevalence were somatic diseases 39% (95%CI 15 to 62), convulsion 38% (95%CI 11 to 65), mental diseases 36% (95%CI 15 to 95) and hereditary development 26% (95%CI 9 to 42). A meta-regression model identified a declining trend in the prevalence of epilepsy within Iran for the last decade. Pooled analyses from the nine included publications in this review estimate the prevalence of epilepsy in Iran to be around 5%. Although this result is much higher than rates in other countries, a declining trend in prevalence over the past decade was also identified.

The high prevalence of COVID-19 has been paied lots of attention all over the world. Nurses are in the first line against this infection and they placed in a high-risk situation. This study aimed to report COVID-19 infection during patients care among nures in the Mostafa Khomini Hospital, Ilam, Iran. In this hospital 125 nurses were enrolled in COVID-19 center. In the present study 5 out of 125 nurses (4%) who enrolled in COVID-19 infection center, were infected with COVID-19. They were first positive for real-time PCR but the CT scan was positive for just one of them. None of the infected nurses were hospitalized and all of them preferred to be quarantine at home and receive the necessary care and treatment (Oseltamivir, Azithromycin and Kaletra. This study showed that regardless of self caring, the nurses were exposed to COVID-19. Because at the the beginning of SARS-CoV-2 outbreak in Iran, there were no special protection against this infection.Therfore they were at risk for the COVID-19.This study also reported that receiving the necessary care and treatment at home was a good experience for nurses that can be used in some cases.
