Vilazodone is a new molecule approved for major depressive disorder (MDD). This report focuses on the efficacy and tolerability of vilazodone for MDD. MEDLINE, EMBASE, and Cochrane Library were searched. A total of 1,930 patients from four trials were included. A significant improvement in the Montgomery-Asberg Depression Rating Scale (MADRS) total score was seen as early as week 2 (P<0.01) in vilazodone-treated patients. The results showed a higher rate of MADRS response with vilazodone compared with placebo (P<0...

Enterococcus faecium MXVK29 has the ability to produce an antimicrobial compound that belongs to Class IIa of the Klaenhammer classification, and could be used as part of a biopreservation technology through direct inoculation of the strain as a starter or protective culture. However, Enterococcus is considered an opportunistic pathogen, so the purpose of this work was to study the food safety determinants of Enterococcus faecium MXVK29. The strain was sensitive to all of the antibiotics tested (penicillin, tetracycline, vancomycin, erythromycin, chloramphenicol, gentamicin, neomycin, kanamycin and netilmicin) and did not demonstrate histamine, cadaverine, or putrescine formation...

Voluntary medical male circumcision is an integral part of the South African government's response to the HIV and AIDS epidemic. Following circumcision, it is recommended that patients abstain from sexual activity for six weeks, as sex may increase the risk of female-to-male HIV transmission and prolong the healing period. This paper investigates the resumption of sexual activity during the healing period among a cohort of school-going males in the KwaZulu-Natal province of South Africa. The analysis for this paper compares two groups of sexually active school-going males: the first group reported having sex during the healing period (n = 40) and the second group (n = 98) reported no sex during the healing period (mean age: 17...

The U.S. Preventive Services Task Force (USPSTF) has issued recommendations on behavioral counseling to prevent sexually transmitted infections (STIs) and recommendations about screening for individual STIs. Clinicians should obtain a sexual history to assess for behaviors that increase a patient's risk. Community and population risk factors should also be considered. The USPSTF recommends intensive behavioral counseling for all sexually active adolescents and for adults whose history indicates an increased risk of STIs...

Inflammation of the epididymis, or epididymitis, is commonly seen in the outpatient setting. Etiology and treatment are based on patient age and the likely causative organisms. Epididymitis presents as the gradual onset of posterior scrotal pain that may be accompanied by urinary symptoms such as dysuria and urinary frequency. Physical findings include a swollen and tender epididymis with the testis in an anatomically normal position. Although the etiology is largely unknown, reflux of urine into the ejaculatory ducts is considered the most common cause of epididymitis in children younger than 14 years...

Female sexual dysfunction (FSD) is defined as disturbances in sexual desire and the psychophysiological changes that characterize the sexual response cycle, which cause marked distress and interpersonal difficulty. Female sexual dysfunction is strongly related to socio-cultural characteristics of a certain region and can change over time. Authors previously reported the features of FSD in Korea through an analysis of an internet-based survey conducted in 2004. This time, we designed a 10-year interval study to compare the prevalence of and risk factors of FSD through the Korean Internet Sexuality Survey (KISS) 2014...

The clustering of human papillomavirus (HPV) infections in some individuals is often interpreted as the result of common risk factors rather than biological interactions between different types of HPV. The intraindividual correlation between times-at-risk for all HPV infections is not generally considered in the analysis of epidemiologic studies. We used a deterministic transmission model to simulate cross-sectional and prospective epidemiologic studies measuring associations between 2 HPV types. When we assumed no interactions, the model predicted that studies would estimate odds ratios and incidence rate ratios greater than 1 between HPV types even after complete adjustment for sexual behavior...

OBJECTIVE: To identify the unmet needs for HIV prevention among older adults in rural South Africa. METHODS: We analyzed data from a population-based sample of 5059 men and women aged 40 years and older from the study Health and Aging in Africa: Longitudinal Studies of INDEPTH Communities (HAALSI), which was carried out in the Agincourt health and sociodemographic surveillance system in the Mpumalanga province of South Africa. We estimated the prevalence of HIV (laboratory-confirmed and self-reported) and key sexual behaviors by age and sex...

The consequences of the 2013-16 Ebola Zaire virus disease epidemic in West Africa were grave. The economies, healthcare systems and communities of Guinea, Sierra Leone and Liberia were devastated by over 18 months of active Ebola virus transmission, followed by sporadic resurgences potentially related to sexual transmission by survivors with viral persistence in body fluids following recovery. The need to develop and implement strategies to prevent and mitigate future outbreaks is now beyond dispute. The potential for unpredictable outbreaks of indeterminate duration, and control challenges posed by the possibility of sporadic re-emergence, mean that implementation of an effective vaccination programme for outbreak containment necessitates a vaccine providing durable immunity...

The English version of the Condom Self-Efficacy Scale (CSES) was translated, back-translated, and tested among a representative sample of the Hong Kong general population. It then underwent reconsolidation, confirmation, and validation following standard procedures. Construct validity was performed by exploratory factor analysis and item-scale correlation. Independent t-test and effect size were used to identify the score differences between consistent and non-consistent condom users. The factor loading scores of 14 items ranged between 0...

This was a cross-sectional study of sexually active women with sickle-cell disease (SCD) managed at São Paulo Federal University during a one-year period. A total of 54 women were included. Mean age was 32.0 (11.2, standard deviation) years and almost 95% were black or of mixed racial ancestry. Almost 80% reported a history of multiple blood transfusions, 50% had kidney disease and 17% had a history of thrombosis. Over 80% of them had used some form of contraception, mostly combined hormonal contraceptive (52%) or progestin-only contraceptives (46%)...

Children with neurofibromatosis type 1 (NF1) develop low-grade brain tumors throughout the optic pathway. Nearly 50% of children with optic pathway gliomas (OPGs) experience visual impairment, and few regain their vision after chemotherapy. Recent studies have revealed that girls with optic nerve gliomas are five times more likely to lose vision and require treatment than boys. To determine the mechanism underlying this sexually dimorphic difference in clinical outcome, we leveraged Nf1 optic glioma (Nf1-OPG) mice...

Endoproteases in the secretory pathway process pro-cholecystokinin (CCK) into the biologically active forms found in the tissues that express CCK mRNA. Thus far, the endoproteases involved in CCK processing include cathepsin L and the prohormone convertases (PC) 1, 2, and 5. This study finds that PC7 is also critical for normal production of CCK in specific areas of the brain. Loss of PC7 results in decreased levels of CCK in more brain regions than any other endoprotease studied to date. Substantial decreases in brain levels of CCK are found in the prefrontal, frontal, parietal-insular-pyriform, and temporal cortex, caudate-putamen, basal forebrain, thalamus, hippocampus, septum, and medulla of PC7 knock-out (KO) mice...

BACKGROUND: Due to the ability of the 8-aminoquinolines (8AQs) to kill different stages of the malaria parasite, primaquine (PQ) and tafenoquine (TQ) are vital for causal prophylaxis and the eradication of erythrocytic Plasmodium sp. parasites. Recognizing the potential role of cytochrome (CYP) 450 2D6 in the metabolism and subsequent hepatic efficacy of 8-aminoquinolines, studies were designed to explore whether CYP2D-mediated metabolism was related to the ability of single-dose PQ and TQ to eliminate the asexual and sexual erythrocytic stages of Plasmodium berghei...

BACKGROUND: Anesthesia during the synaptogenic period induces dendritic spine formation, which may affect neurodevelopment. The authors, therefore, evaluated whether changes in synaptic transmission after dendritic spine formation induced by sevoflurane were associated with long-term behavioral changes. The effects of sevoflurane on mitochondrial function were also assessed to further understand the mechanism behind spinogenesis. METHODS: Postnatal day 16 to 17 mice were exposed to sevoflurane (2...

WHO recently issued new guidance on the prevention of sexual transmission of Zika virus. The updated guidance states that '[c]ountry health programmes should ensure that… [i]n order to prevent adverse pregnancy and fetal outcomes, men and women of reproductive age, living in areas where local transmission of Zika virus is known to occur, be correctly informed and oriented to consider delaying pregnancy'. While the media has reported this advice as WHO telling couples in Zika-affected regions to avoid pregnancy, WHO states that they are not doing that...

OBJECTIVE: To examine differences in inflammation markers in sexually active versus abstinent women and observe changes in inflammation markers across the menstrual cycle. Cycle-related immune fluctuations may have evolved to reduce interference with conception. If so, reproductively active (i.e., sexually active) women should show the most variability in cytokine expression. DESIGN: Participants provided serum samples at menses and ovulation (from which cytokines were assayed) and saliva samples at menses and during follicular, ovulation, and luteal phases (from which C-reactive protein [CRP] was assayed)...

The most prevalent route of HIV-1 infection is across mucosal tissues after sexual contact. Langerhans cells (LCs) belong to the subset of dendritic cells (DCs) that line the mucosal epithelia of vagina and foreskin and have the ability to sense and induce immunity to invading pathogens. Anatomical and functional characteristics make LCs one of the primary targets of HIV-1 infection. Notably, LCs form a protective barrier against HIV-1 infection and transmission. LCs restrict HIV-1 infection through the capture of HIV-1 by the C-type lectin receptor Langerin and subsequent internalization into Birbeck granules...

OBJECTIVE: Condom distribution programmes are an important means of preventing sexually transmitted infections (STIs); yet little research has examined their perceived and actual impact on college campuses. DESIGN: Quantitative, cross-sectional study. SETTING: Large public university in the Southeastern USA. METHOD: Approximately 2 months after a campus-wide condom distribution programme began, we utilised intercept surveys with 355 students (68% women; 43% racial/ethnic minorities) to examine their perceptions of the availability, accessibility and acceptability of condoms, and their perceptions and use of the newly installed condom dispensers...
