Effects of Migration on Risky Sexual Behavior and HIV Acquisition in South Africa: A Systematic Review and Meta-analysis, 2000-2017.

AIDS Behav 2018 Dec 13. Epub 2018 Dec 13.

Africa Health Research Institute, K-RITH Tower Building, 719 Umbilo Road, Congella, Private Bag X7, Durban, South Africa.

While human mobility has been implicated in fueling the HIV epidemic in South Africa, the link between migration and HIV has not been systematically reviewed and quantified. We conducted a systematic review of the role of migration in HIV risk acquisition and sexual behaviour based on 29 studies published between 2000 and 2017. Furthermore, we performed a meta-analysis of the association between migration and HIV risk acquisition in four of the studies that used HIV incidence as an outcome measure. Read More

GnRH Neurons Provide Direct Input to Hypothalamic Tyrosine Hydroxylase Immunoreactive Neurons Which Is Maintained During Lactation.

Front Endocrinol (Lausanne) 2018 22;9:685. Epub 2018 Nov 22.

Laboratory of Endocrine Neurobiology, Institute of Experimental Medicine, Hungarian Academy of Sciences, Budapest, Hungary.

Gonadotropin releasing hormone (GnRH) neurons provide neuronal input to the preoptic area (POA) and the arcuate nucleus (Arc), two regions involved critically in the regulation of neuroendocrine functions and associated behaviors. These areas contain tyrosine hydroxylase immunoreactive (TH-IR) neurons, which play location-specific roles in the neuroendocrine control of both the luteinizing hormone and prolactin secretion, as well as, sexually motivated behaviors. Concerning changes in the activity of GnRH neurons and the secretion pattern of GnRH seen under the influence of rising serum estrogen levels and during lactation, we tested the hypothesis that the functional state of GnRH neurons is mediated via direct synaptic connections to TH-IR neurons in the POA and Arc.

Methods: Analyses of data reported by 10 759 sexually active people aged 16-74 y interviewed for a British national probability survey undertaken in 2010-12. Computer-assisted self-interviews asked about partner numbers and characteristics of participants' three most recent partnerships (MRPs). Read More

Peripheral oxytocin and vasopressin modulates regional brain activity differently in men and women with schizophrenia.

Schizophr Res 2018 Dec 6;202:173-179. Epub 2018 Jul 6.

Department of Radiology, West China Hospital of Sichuan University, Chengdu, People's Republic of China; Department of Psychiatry, University of Texas Southwestern Medical Center, Dallas, TX, United States of America; Department of Psychiatry, University of Cincinnati, United States of America.

Background: Oxytocin (OT) and arginine vasopressin (AVP) exert sexually dimorphic effects on cognition and emotion processing. Abnormalities in these hormones are observed in schizophrenia and may contribute to multiple established sex differences associated with the disorder. Here we examined sex-dependent hormone associations with resting brain activity and their clinical associations in schizophrenia patients. Read More

Nativity Homogeneity in Social Networks and Prostitution Patronage Among Male Migrant Laborers.

AIDS Behav 2018 Dec 11. Epub 2018 Dec 11.

Children's Hospital, Zhejiang University School of Medicine, Hangzhou, China.

Previous studies have repeatedly found the association between network homogeneity based on native-place and sexual risk behaviors among migrants. However, it remains unclear why such a simple numerical property of network composition can be correlated with a sexual risk behavior. Using a dataset (n = 1591) with detailed information on the sexual behaviors among male migrant laborers in the two Chinese provinces with the highest migrant inflows, we confirmed network homogeneity is significantly associated with prostitution patronage.

Mediating Effects of Depressive Symptoms on Perceived Social Support and HIV Disclosure: Assessing Moderation by Sex.

AIDS Behav 2018 Dec 11. Epub 2018 Dec 11.

Department of Mental Health Law and Policy, College of Behavioral and Community Sciences, University of South Florida, Tampa, FL, USA.

People living with HIV may decide to disclose their HIV-positive status after considering the benefits and costs. Studies have shown associations between perceived social support, depressive symptoms and HIV disclosure among men and women; however, research assessing the mediating pathway among these variables and the associated disparities by sex are lacking. Therefore, the aims of this study were to determine the association between perceived social support from family and friends and HIV disclosure to sexual partners; assess the mediating effects of depressive symptoms; and examine the disparities by sex.

Trends in Attitudes to and the Use of HIV Pre-exposure Prophylaxis by Australian Gay and Bisexual Men, 2011-2017: Implications for Further Implementation from a Diffusion of Innovations Perspective.

AIDS Behav 2018 Dec 11. Epub 2018 Dec 11.

Centre for Social Research in Health, UNSW Sydney, Sydney, Australia.

Using repeated, national, online, cross-sectional surveys of Australian gay and bisexual men (GBM), we analysed trends related to HIV pre-exposure prophylaxis (PrEP). Specifically, we analysed trends in PrEP use, willingness to use PrEP, and concern about using PrEP during 2011-2017. We assessed support for GBM using PrEP and willingness to have sex with men taking PrEP between 2015 and 2017. Read More

Neuronal nitric oxide synthase activity mediates Lycium barbarum polysaccharides-enhanced sexual performance without stimulating noncontact erection in rats.

Psychopharmacology (Berl) 2018 Dec 11. Epub 2018 Dec 11.

Department of Physical Therapy, Hung Kuang University, No. 1018, Sec. 6, Taiwan Boulevard, Shalu District, Taichung, 43302, Taiwan.

Rationale: Lycium barbarum polysaccharide (LBP) is known to promote reproductive functions. However, its role in noncontact erection (NCE) of penis initiated by brain regions including medial preoptic area (MPOA) and paraventricular nucleus (PVN) regions responsible for sexual behavior has not been investigated.

Objectives: Therefore, this study initially investigated the effects of LBP on male sexual function, and subsequently, the mechanistic insight was investigated through assessing the expression of neuronal nitric oxide synthase (nNOS) in the MPOA and PVN. Read More

Antimicrobial Consumption and Susceptibility of : A Global Ecological Analysis.

Front Med (Lausanne) 2018 27;5:329. Epub 2018 Nov 27.

Department of Reproductive Health and Research, World Health Organization, Geneva, Switzerland.

The reasons why antimicrobial resistance in has emerged explosively in certain populations but not others are poorly understood. We hypothesized that population level consumption of antimicrobials plays a role. Using susceptibility data from the World Health Organizations Global Gonococcal Antimicrobial Surveillance Programme and antimicrobial consumption data from the IMS Health MIDAS database we built linear regression models with country-level cephalosporin, macrolide, and fluoroquinolone consumption (standard doses/1,000 population/year) as the explanatory variable and 1-year lagged ceftriaxone, azithromycin, and ciprofloxacin resistance as the outcome variables.

Genetic Model to Study the Co-Morbid Phenotypes of Increased Alcohol Intake and Prior Stress-Induced Enhanced Fear Memory.

Front Genet 2018 27;9:566. Epub 2018 Nov 27.

Department of Pharmacology, University of Tennessee Health Science Center, Memphis, TN, United States.

Posttraumatic Stress Disorder (PTSD) is a complex illness, frequently co-morbid with depression, caused by both genetics, and the environment. Alcohol Use Disorder (AUD), which also co-occurs with depression, is often co-morbid with PTSD. To date, very few genes have been identified for PTSD and even less for PTSD comorbidity with AUD, likely because of the phenotypic heterogeneity seen in humans, combined with each gene playing a relatively small role in disease predisposition.
