In this study, we evaluated if male circumcision was associated with lower HIV acquisition for HIV (−) males and HIV (−) females during normal sexual behavior. We performed a systematic literature search of PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) databases to identify studies that compared HIV acquisition for the circumcised and uncircumcised groups. The reference lists of the included and excluded studies were also screened. Fifteen studies (4 RCTs and 11 prospective cohort studies) were included, and the related data were extracted and analyzed in a meta-analysis. Our study revealed strong evidence that male circumcision was associated with reduced HIV acquisition for HIV(−) males during sexual intercourse with females [pooled adjusted risk ratio (RR): 0.30, 95% CI 0.24 0.38, P < 0.00001] and provided a 70% protective effect. In contrast, no difference was detected in HIV acquisition for HIV (−) females between the circumcised and uncircumcised groups (pooled adjusted RR after sensitivity analysis: 0.68, 95%CI 0.40–1.15, P = 0.15). In conclusion, male circumcision could significantly protect males but not females from HIV acquisition at the population level. Male circumcision may serve as an additional approach toward HIV control, in conjunction with other strategies such as HIV counseling and testing, condom promotion, and so on.
Tamsulosin is a safe and effective therapy for renal and ureteral stones after SWL. Further, high-quality randomized trials are necessary to confirm its efficacy.
A 44-year-old woman who underwent radical nephrectomy due to a left renal mass presented to our clinic. Results of the histopathological examination showed a mixed epithelial and stromal tumor of the kidney, a rare benign lesion of the kidney. The epidemiology, histopathological features, imaging features, possible pathogeneses, and treatment alternatives are discussed, and the relevant literature is reviewed. The postoperative course was uneventful, and the patient was free of local recurrence or metastasis until the last follow-up (12 months).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
