As a concentrated epidemic, human immunodeficiency virus (HIV) is spreading rapidly in one or more groups in Iran, but in the general population its prevalence is relatively low. Female sex workers (FSWs) and their partners are at greater risk for HIV infection. To determine the prevalence of HIV and sexually transmitted infections (STIs) including gonorrhoea, Chlamydia, herpes simplex type 2 and syphilis among FSWs. We conducted a cross-sectional study of 278 FSWs in Shiraz, by using respondent-driven sampling, from June to March 2010. The recruitment chain started with 14 seeds, and FSWs were tested for HIV, syphilis, herpes simplex type 2, gonorrhoea and Chlamydia. HIV prevalence was 4.7% (13/278); the most prevalent STI was herpes simplex type 2, 9.7% (27/278), followed by Chlamydia 9% (25/278), gonorrhoea 1.4% (4/278) and syphilis (0/278). The FSWs reported drug use (69.9%) of which 16.4% had history of injecting drug use. Unprotected sex in the past month was reported by 24.4% of FSWs. Urgent education and risk reduction programmes are needed in this population.

Islets transplantation, as a treatment of type 1 diabetes, faces challenges, including the loss of islets in the process of isolation and pre-transplantation due to cellular stresses-induced apoptosis. Accordingly, the optimization of culture plays a decisive role in the transplantation success. In this study, we evaluated the effect of nobiletin on the cultured human islets. Isolated human islets were treated by different concentrations of nobiletin and cultured for 24 and 72 hours. Then, the islets viability, apoptosis, insulin and C-peptide secretion, and apoptosis markers were evaluated. Also, the production of reactive oxygen species (ROS), hypoxia inducible factor 1 alpha (HIF-1α), and its target genes in the islets were examined. Our findings showed that the islets were encountered with hypoxia and oxidative stress after isolation and during culture. These insults induced apoptosis and reduced viability during culture period. Moreover, the secretion of insulin and C-peptide decreased. Nobiletin treatments significantly improved the islets survival through reduction of HIF-1α and ROS production and suppression of apoptosis, along with increased islets function. Islet protective effect of nobiletin might be related to its anti-oxidant, anti-apoptotic and insulinotropic properties. Hence, in order to achieve viable and functional islets for clinical transplantation, the application of nobiletin during pre-transplantation period is useful.

Background COVID‐19 has been spreading worldwide with a significant death toll. Solid‐organ transplantation (SOT) recipients are at higher risk due to their suppressed immune system. In this study, we aimed to conduct a systematic review on COVID‐19 clinical manifestations and treatment strategies in SOT recipients. Methods We searched three databases for relevant terms related to COVID‐19 and transplantation. 50 studies, including 337 patients, were reviewed. Results 236 patients were male, with a mean age of 49.9 years. The most prevalent group was the kidney 57.0%, followed by 17.2% heart, and 13.6% liver. Fever and Cough were the most reported clinical presentations. Infiltration (55.4%) in chest x‐ray and ground‐glass opacity (67.1%) in CT scans were the most radiological findings. It was found that 96.8% and 72.4% of patients present with CRP level and lymphocytopenia, respectively, and 70.6% of kidney recipients patients presented with high creatinine levels. The most common baseline immunosuppressants were Calcineurin inhibitors (88.9%), and antimetabolites (73.2%). Antimetabolites (84.3%) and Calcineurin inhibitors (54.3%) were discontinued/decreased 84.3% whereas glucocorticoids dosage almost have no change (77.9%) or even increased. 18.4% of cases had died, and 65.9% were discharged. Conclusions Patients’ demographics, signs, symptoms, and radiographic findings in SOT recipients are almost similar to the general population. However, gastrointestinal symptoms appear to be more common. There are different treatment strategies, but in most of them, antimetabolite and Calcineurin inhibitors were decreased or discontinued, while corticosteroids were increased. Finally, Covid‐19 seems to be more severe and has higher mortality in SOT recipients compared to the general population.

This quasi-experimental, before-after study was designed to assess the effect of an educational intervention on knowledge and attitudes about sexually transmitted infections, HIV and preventive behaviours among female sex workers in Shiraz, Iran. A single-group pre-post test design was used and the study was done between August and December 2009. The participants were 80 female sex workers recruited from three drop-in centers in Shiraz, with stratified random sampling. Pre-intervention knowledge was assessed by interview with a standard questionnaire. The educational intervention consisted of a lecture, face-to-face education, printed information, an educational movie, role playing and a contest. After 2 months, the effect of the intervention was evaluated (post-test). The average age of the participants was 32.6 ± 9.1 years. After the intervention, the mean score for general knowledge about HIV and sexually transmitted infections increased from 13.7 ± 0.95 (pre-test) to 19.47 ± 11.62 (post-test, p<0.001). There were significant improvements in attitude and the number of participants who self-reported preventive behaviours such as using a condom consistently (from 45 to 63) (p<0.001). The results show that the educational programme was successful in increasing the participants' HIV- and AIDS-related knowledge and attitudes, and in decreasing their risk behaviours.
