Background. Breast cancer is still considered as one of the most important diseases, the most common cancer, and the second cause of death among women. It is necessary to evaluate the factors responsible for breast cancer (e.g., marital stress) since majority of the breast cancer cases in Iran are active young women hoping to live a normal social and sexual life, and because breast emptying has destructive effects on self-image and marital satisfaction. Therefore, this study aimed to determine the relationship between satisfaction and marital stress in mastectomy surgery.Methods. In this cross-sectional study, 120 married women with breast cancer were selected using available methods. The data were collected using a questionnaire with three parts including demographic questions, Enrich marital satisfaction, and Stockholm marital stress. Parametric tests and analysis of variance were used to analyze the data.Results. There was no significant relationship between marital satisfaction/marital stress and type of mastectomy surgery (P>0.01). Also, there was no significant relationship between marital satisfaction/marital stress and demographic variables (P>0.01).Conclusion. It was concluded that the marital satisfaction and marital stress had no significant relationship with the type of breast surgery.Practical Implications. Type of breast surgery had no effect on marital stress and satisfaction.

Background Gender-based violence (GBV) includes any physical, sexual, psychological, economic harms, and any suffering of women in the form of limiting their freedom in personal or social life. As a global crisis, COVID-19 has exposed women to more violence, which requires serious actions. This work aims to review the most critical dimensions of the GBV against women, effective factors on it, and strategies for combating it during the COVID-19 pandemic in order to provide recommendations for future pandemics. Methods This study was conducted based on PRISMA-ScR. First, PubMed, Embase, Scopus, Web of Science, ProQuest, and Google Scholar were searched in April 2021 with no time limitation and location using the related keywords to COVID-19 and GBV. The searched keywords were COVID-19, gender-based violence, domestic violence, sexual violence, women, violence, abuse, and their synonyms in MESH and EMTREE. Duplicates were removed, titles and abstracts were screened, and then the characteristics and main results of included studies were recorded in the data collection form in terms of thematic content analysis. Results A total of 6255 records were identified, of which 3433 were duplicates. Based on inclusion criteria 2822 titles and abstracts were screened. Finally, 14 studies were eligible for inclusion in this study. Most of these studies were conducted in the United States, the Netherlands, and Iran, mostly with interventional and qualitative methods. Conclusions Strengthening ICT infrastructure, providing comprehensive government policies and planning, government economic support, social support by national and international organizations should be considered by countries worldwide. It is suggested that countries provide sufficient ICT infrastructure, comprehensive policies and planning, economic support, social support by collaboration between national and international organizations, and healthcare supporting to manage incidence of GBV against women in future pandemics.

Background: The rapid spread of COVID-19 virus from China to other countries and outbreaks of disease require an epidemiological analysis of the disease in the shortest time and an increased awareness of effective interventions. The purpose of this study was to estimate the COVID-19 epidemic in Iran based on the SIR model. The results of the analysis of the epidemiological data of Iran from January 22 to March 24, 2020 were investigated and prediction was made until April 15, 2020. Methods: By estimating the three parameters of time-dependent transmission rate, time-dependent recovery rate, and timedependent death rate from Covid-19 outbreak in China, and using the number of Covid-19 infections in Iran, we predicted the number of patients for the next month in Iran. Each of these parameters was estimated using GAM models. All analyses were conducted in R software using the mgcv package. Results: Based on our predictions of Iran about 29000 people will be infected from March 25 to April 15, 2020. On average, 1292 people with COVID-19 are expected to be infected daily in Iran. The epidemic peaks within 3 days (March 25 to March 27, 2020) and reaches its highest point on March 25, 2020 with 1715 infected cases. Conclusion: The most important point is to emphasize the timing of the epidemic peak, hospital readiness, government measures and public readiness to reduce social contact.

Background There is a controversy about the association between vitamin D and cardiovascular diseases (CVDs). The effect of serum 25-OH-vitD on the risk of CVDs was evaluated. Methods Major electronic databases including Scopus, Science Direct, and PubMed were searched. All prospective cohort studies on the relationship between vitamin D status and CVDs conducted between April 2000 and September 2017 were included, regardless language. The study participants were evaluated regardless of their age, sex, and ethnicity. The Newcastle-Ottawa Scale was used to assess the quality of the studies. Two investigators independently selected the studies and extracted the data. The designated effects were risk ratio (RR) and hazard ratio (HR). The random effects model was used to combine the results. Results A meta-analysis of 25 studies with 10,099 cases of CVDs was performed. In general, a decrease in the level of vitamin D was associated with a higher relative risk of CVDs (incidence-mortality combined) (RR = 1.44, 95% CI: 1.24–1.69). This accounts for 54% of CVDs mortality rate (RR = 1.54, 95% CI: 1.29–1.84(. However, no significant relationship was observed between the vitamin D status and incidence of CVDs (RR = 1.18, 95% CI: 1–1.39). In general, low serum vitamin D level increased the risk of CVD by 44% (RR = 1.44, 95% CI: 1.24–1.69). It also increased the risk of CVD mortality (RR = 1.54, 95% CI: 1.29–1.84) and incidence rates (RR = 1.18, 95% CI: 1–1.39). Conclusions The findings showed that vitamin D deficiency increases the CVDs mortality rate. Due to the limited number of studies on patients of the both genders, further research is suggested to separately evaluate the effect of vitamin D status on CVD in men and women.

Background This study aims to determine the prevalence of physical inactivity in Iranian adolescents aged 10–12 years and the impact of socioeconomic inequality on it. Methods In this descriptive study, the study population consisted of 10–12 years old adolescents from an Iranian population from Kurdistan, Fars and Markazi provinces in 2018. The sample size was 1590 individuals. The sampling method was cluster sampling. Data was collected using demographic questionnaire, modifiable activity questionnaire (MAQ) and socioeconomic questionnaire. Cut points on the MAQ for light activity, moderate activity and heavy activity were MET< 3, MET = 3–6 and MET> 6, respectively. Linear and logistic regression were used to estimate the final model and the Oaxaca analysis method was applied. All analyses were performed in Stata/SE 14.0. Results Of the 1590 participants, 52.82% were male. The results showed that 25.79% of the subjects were physically inactive and 7.30% engaged in moderate physical activity during the week. The average physical activity during 1 week was more in boys than in girls ( P -value< 0.05). Adolescents of mothers with secondary and high school education were more likely to have physical inactivity than mothers with a high school diploma or higher (AOR: 1.35, 95% CI: 1.02–1.77). The concentration index was −.11, indicating a greater concentration of physical inactivity in adolescents with low socioeconomic levels. Conclusion One-fourth of the study population had physical inactivity in this age group. Socioeconomic levels, parental literacy, and sex of adolescents were associated with the level of physical activity.

Background This study aimed at determining the prevalence of and risk factors for hepatitis B virus (HBV) and hepatitis C virus (HCV) among incarcerated people who inject drugs (PWID) in Iran in 2015–16. Methods The required data was collected from a database provided by Iranian national bio-behavioral surveillance surveys (BBSSs) on 11,988 prisoners selected from among 55 prisons in 19 provinces in 2015–16. The data on demographics and behavioral variables were collected through interviews and the status of exposure to HBV and HCV were determined using ELISA blood test. A total of 1387 individuals with a history of drug injection in their lifetime were enrolled into the study. Data were analyzed using the survey package in Stata/SE software, Version 14.0. Univariate and multivariate logistic regression tests were used to investigate the relationships between risk factors and outcomes. Results The mean age of the incarcerated PWID was 36.83 ± 8.13 years. Of all the studied subjects, 98.46% were male and 50.97% were married. The prevalence of HCV and HBV among the subjects were 40.52 and 2.46%, respectively. The prevalence of HCV was associated with age ≥ 30 years, being single, illiteracy and low level of education, prison term> 5 years, history of piercing, and extramarital sex in lifetime ( P  < 0.05). Conclusions The prevalence of HCV is alarmingly high. In general, it is recommended to adopt measures to screen and treat patients with HCV and vaccinat incarcerated PWID without a history of vaccination against HBV.

Background Healthcare workers including physicians, dentists, nurses and laboratory workers are considered to be among the groups at the risk of blood-borne pathogen transmission. Thus, it is necessary to evaluate the Knowledge, Attitude, and Practices (KAP) of dentists regarding infection control and basic principles. Methods This cross-sectional study recruited 106 dentists in Sanandaj, Iran. The dentists’ KAP regarding hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV/AIDS were evaluated. Chi-square test, student’s t-test, and one-way ANOVA were used to assess differences between the groups. Data were analyzed in Stata 12. Results The results showed that the majority of the subjects in the study population (53.8%) were female. The mean ± standard deviation ( SD ) for age and work experience was 39.6 ± 9.80 and 10.6 ± 8.7 years, respectively. The mean ± SD for knowledge, attitude and practices of participants was 37.3 ± 3.01, 22.9 ± 4.80 and 24.07 ± 5.06, respectively. The results also indicated that dentists’ higher level of knowledge about HBV, HCV and HIV/AIDS was significantly influenced by work experience (≥10 years; P  < 0.001) and graduation year (after 2006: P  < 0.001). Positive attitude towards HBV, HCV and HIV/AIDS was considerably influenced by age group (< 30 years: P  = 0.021), work experience (≥10 years: P  < 0.001), and workplace (dental office: P  = 0.016). Conclusions The results of this study demonstrated a satisfactory level of knowledge and attitude of dentists about HBV, HCV and HIV/AIDS infections, but some gaps were observed, suggesting that higher knowledge level of dentists plays a very important role in forming the attitudes and practices regarding patients with HBV, HCV and HIV/AIDS.

Background Simultaneous occurrence of colorectal malignancy with pelvic kidney has been considered a rare phenomenon. A review of the related literature revealed three previous reports of rectal cancer and pelvice kidney. Case presentation This case report describe the case of 40-year-old Asian man with complaints of bleeding and a feeling of discomfort in his anus. A colonoscopy revealed a raised large multilobulated mass in his rectum. Multiple biopsies of the lesion were done after detecting a tumor in his rectum 4 cm above the dentate line; a diagnosis of rectal adenocarcinoma was made by pathological examinations. Subsequent investigations, carried out by computed tomography (CT) scans, incidentally showed an ectopic pelvic kidney. Because of the progress of the rectal cancer, our patient was a candidate for neoadjuvant radiotherapy. Six weeks after radiotherapy, he underwent total mesorectal excision (TME) surgery maintaining the ectopic kidney after using a coloanal anastomosis for additional curative surgery. A very low anterior resection surgery was performed to maintain the ectopic kidney. Thereafter, adjuvant chemotherapy was performed. Conclusions Due to the proximity of the tumor to the pelvic viscera, especially the ectopic kidney, the probability of inadequate abscission of the lesion in surgery and radiotherapy, as well as complications and localized relapse were increased so that the kidney could be maintained. Carrying out careful pre-treatment examinations can result in maintaining an ectopic kidney and its daily conditioned function dependent on the status of the patient, including the proximity of the ectopic kidney to the tumor, anatomical position, and prior damage. The lesson learned from the present case is that radiotherapy and surgery are possible treatments in the presence of pelvic kidney and rectal cancer without incurring renal damage.

Background The reproductive health and Prevention of Mother-to-Child Transmission (PMTCT) of HIV programs in Iran were integrated as a pilot project in September 2014. This study aims to provide a comprehensive evaluation and analysis of the PMTCT of HIV program in Iran. Methods The pilot phase of PMTCT of HIV was launched in early September 2014 in selected centers including 170 health centers and 40 hospitals affiliated to medical universities of 16 provinces of Iran. In each medical university, a researcher-made checklist was administered to all newly-diagnosed HIV-positive pregnant women by an AIDS expert. Data was analyzed using SPSS 19. Results Overall, 69.4% of eligible pregnant women were enrolled in the pilot phase. From 134 reactive cases, 76 (56.7%) were confirmed as HIV positive. ARV consumption was irregular in 10 (13.2%) of HIV positive pregnant women. Also, 82.5% had CD4 count more than 350 after treatment, with an average of 55.5% increase in the number of CD4 in comparison to the baseline, and 84.8% had viral load suppression (< 200 copies/ml). Counseling and testing was done for the husbands of 75% of the women that resulted in the identification of 15 (39.5%) new HIV cases among husbands. Among the tested individuals, 23 (60.5%) males already knew their HIV status and were registered as HIV patients. HIV was diagnosed in one (1.5%) newborn. Conclusion Implementation of rapid HIV testing and PMTCT in Iran is one of the strengths of the national HIV control program. To eliminate MTCT, it is necessary to understand and overcome the barriers and challenges to the program in the pilot phase.

Background The population-based survival rate is affected by the quality and effectiveness of health care systems. Overall, the survival of prostate cancer (PC) patients has improved over the past two decades worldwide. This study aimed to determine the overall survival rate and correlate it with the prognostic factors in patients with PC diagnosed in Kurdistan province. Methods In a retrospective cohort study, 410 PC patients registered in Kurdistan province population-based cancer registry from March 2011 to 2018 were recruited. Kaplan–Meier method and log-rank test were used to analyze the overall survival rates of PC patients. A Multivariate Cox regression model was used to determine adjusted hazard ratios for different variables. Results Of 410 patients with PC, 263 (64.1%) died within seven years due to the disease. The 1, 3, and 5 years survival rates were 93, 64.1, and 40.7%, respectively. According to the results of multiple Cox regression, the following factors were significantly related to PC survival: age at diagnosis (≥81-years old) (HR=2.23, 95% CI: 1.23-4.42) and 71-80 years old was (HR=1.26, 95% CI: 1.12-2.31), occupation (employee) (HR=0.42, 95% CI: 0.20–0.87), educational level: academic (HR=0.78, 95% CI: 0.64–0.91), AJCC stage of disease (HR=2.18, 95% CI: 1.9–3.68), Gleason score ≥ 9 (HR=7.12, 95% CI: 5.35–10.28), and Gleason score= 8 (HR=4.16, 95% CI: 2.50–6.93). There was less mortality rate among the patients who had received active care, radical prostatectomy, radiotherapy, combined treatment, and orchiectomy had a lower mortality rate than those who received no treatment ( P <0.05). Conclusions This study demonstrated that factors such as age at diagnosis, level of education, occupation, AJCC stage of disease, Gleason score, and type of treatments were influential factors in the survival of PC patients in Kurdistan province and needed more attention.
