Prevalence of violence victimisation and poly-victimisation among female sex workers in Haiphong, Viet Nam: A cross-sectional study.

This cross-sectional study is the first to describe the prevalence of violence and poly-victimisation among 310 female sex workers (FSWs) who were cisgender in Haiphong, Viet Nam. An adapted version of the WHO-Multi-Country Study on Violence against Women Survey Instrument was administered to assess physical, sexual, economic and emotional forms of violence perpetrated by an intimate partner, paying partner/client, and/or others (e.g.

The Intracellular Distribution of the Small GTPase Rho5 and Its Dimeric Guanidine Nucleotide Exchange Factor Dck1/Lmo1 Determine Their Function in Oxidative Stress Response.

Rho5, the yeast homolog of human Rac1, is a small GTPase which regulates the cell response to nutrient and oxidative stress by inducing mitophagy and apoptosis. It is activated by a dimeric GEF composed of the subunits Dck1 and Lmo1. Upon stress, all three proteins rapidly translocate from the cell surface (Rho5) and a diffuse cytosolic distribution (Dck1 and Lmo1) to mitochondria, with translocation of the GTPase depending on both GEF subunits.

The small GTPase KlRho5 responds to oxidative stress and affects cytokinesis.

Rho5 is the yeast homolog of the human small GTPase Rac1. We characterized the genes encoding Rho5 and the subunits of its dimeric activating guanine-nucleotide-exchange factor (GEF), Dck1 and Lmo1, in the yeast Kluyveromyces lactis. Rapid translocation of the three GFP-tagged components to mitochondria upon oxidative stress and carbon starvation indicate a similar function of KlRho5 in energy metabolism and mitochondrial dynamics as described for its Saccharomyces cerevisiae homolog.

Analysis of Functional Domains in Rho5, the Yeast Homolog of Human Rac1 GTPase, in Oxidative Stress Response.

The small GTPase Rho5 of is required for proper regulation of different signaling pathways, which includes the response to cell wall, osmotic, nutrient, and oxidative stress. We here show that proper in vivo function and intracellular distribution of Rho5 depends on its hypervariable region at the carboxyterminal end, which includes the CAAX box for lipid modification, a preceding polybasic region (PBR) carrying a serine residue, and a 98 amino acid-specific insertion only present in Rho5 of but not in its human homolog Rac1. Results from trapping GFP-Rho5 variants to the mitochondrial surface suggest that the GTPase needs to be activated at the plasma membrane prior to its translocation to mitochondria in order to fulfil its role in oxidative stress response.

The Small Yeast GTPase Rho5 and Its Dimeric GEF Dck1/Lmo1 Respond to Glucose Starvation.

Rho5 is a small GTPase of and a homolog of mammalian Rac1. The latter regulates glucose metabolism and actin cytoskeleton dynamics, and its misregulation causes cancer and a variety of other diseases. In yeast, Rho5 has been implicated in different signal transduction pathways, governing cell wall integrity and the responses to high medium osmolarity and oxidative stress.

How the Interaction of Childhood Sexual Abuse and Gender Relates to HIV Risk Practices among Urban-Dwelling African Americans.

Purpose: Previous research has demonstrated that HIV risk practices often differ based on gender and on whether or not people experienced sexual abuse during their formative (i.e., childhood and adolescence) years.

The Value of Using a Syndemics Theory Conceptual Model to Understand the Factors Associated with Obesity in a Southern, Urban Community Sample of Disadvantaged African-American Adults.

For this study, a syndemics theory approach was used to examine the factors associated with adulthood obesity in a community-based sample of African-American adults. Interviews were conducted with 1,274 African-American adults residing in Atlanta, Georgia in 80 strategically chosen census tracts, selected on the basis of factors such as low household income, low levels of educational attainment among heads of household, and low levels of labor force participation. Comparisons were made between normal-weight persons (body mass index [BMI] = 18.

Sex Partner Type, Drug Use and Condom Use Self-Efficacy Among African Americans from Disadvantaged Neighborhoods: Are Associations with Consistent Condom Use Moderated by Gender?

Gender inequalities in sexual behavior are explored from the perspective of the theory of gender and power. This study focused on the effect of sex partner type (steady versus casual), drug use, and condom use self-efficacy regarding consistent condom use (CCU) among a community-based sample of adults. The sample included 1,357 African American men and women (M age 37.

A dyadic model of living with epilepsy based on the perspectives of adults with epilepsy and their support persons.

Epilepsy is a chronic condition that significantly affects the lives of individuals with epilepsy and their support persons, though few studies have examined the experiences of both. To examine these experiences and explore the interpersonal relationships between dyad members, we conducted in-depth interviews with 22 persons with epilepsy and 16 support persons. Data analysis was guided by a grounded theory perspective.

Exploring gender norms, agency and intimate partner violence among displaced Colombian women: A qualitative assessment.

Women displaced by conflict are often exposed to many factors associated with a risk of intimate partner violence (IPV) such as high levels of community violence and the breakdown of social support systems. Previous research found that Colombian women perceived IPV to increase after displacement. This study explored how the experience of displacement altered gendered roles in ways that influenced the risk of IPV.

Prediction of HIV Sexual Risk Behaviors Among Disadvantaged African American Adults Using a Syndemic Conceptual Framework.

The focus of this paper is on HIV sexual risk taking among a community-based sample of disadvantaged African American adults. The objective is to examine multiple factors associated with sexual HIV risk behaviors within a syndemic conceptual framework. Face-to-face, computer-assisted, structured interviews were conducted with 1535 individuals in Atlanta, Georgia.

Who Do Smokers Feel Ought to Be Responsible for Informing People about the Dangers Associated with Smoking and Regulating Smoking Behaviors?

Purpose: The focus of this paper is to examine the extent to which a community-based sample of current cigarette smokers believes it to be the responsibility of outside persons and agencies to inform the public about the dangers of smoking and/or to regulate smoking behaviors (herein termed REGULATE). Also investigated is how REGULATE relates to smokers' attitudes toward cigarette smoking and actual smoking practices, and whether REGULATE matters when the influence of other key variables is taken into account.

Method: Questionnaire-based interviews were conducted with a community-based sample of 485 adult current cigarette smokers recruited from the Atlanta, Georgia metropolitan area.

Managing One's Symptoms: A Qualitative Study of Low-Income African Americans With Advanced Cancer.

Background: African Americans endure disproportionately high advanced cancer rates and also are disproportionately represented in the lower socioeconomic strata. These individuals work to manage symptoms in order to function and have a satisfactory quality of life.

Objective: The purpose of this study was to discover what low-income African American adults with advanced cancer do on a day-to-day basis to relieve and manage symptoms.

Perpetration of physical and sexual abuse and subsequent fathering of pregnancies among a cohort of young South African men: a longitudinal study.

Background: Young men's involvement in fathering pregnancies has been substantially neglected in unintended pregnancy research. Gender norms give men substantial power and control over sexual encounters, suggesting that understanding men's role is imperative. We tested the hypothesis that young, unmarried South African men who had perpetrated intimate partner violence (IPV) have a greater incidence of fathering pregnancies.

Perspectives of adults with epilepsy and their support persons on self-management support.

Social support is an important mechanism for improving self-management, although little is known about its role in epilepsy self-management. We examined the type of support provided to people with epilepsy and its influence on self-management. We conducted in-depth interviews with 22 people with epilepsy and 16 support persons, representing 14 pairs and 10 unpaired individuals.

Risk factors for unplanned and unwanted teenage pregnancies occurring over two years of follow-up among a cohort of young South African women.

Background: Although teenage pregnancies in South Africa have declined, the short and longer term health and social consequences are a potential public health concern. This longitudinal study aimed to describe the range of risk and protective factors for incident unwanted and unplanned pregnancies occurring over 2 years of follow-up among a cohort of adolescent women in the Eastern Cape, South Africa. It also investigated the relationship between gender inequality and gender-based violence and subsequent unplanned and unwanted pregnancies among the cohort.

Will HIV vaccination reshape HIV risk behavior networks? A social network analysis of drug users' anticipated risk compensation.

Background: An HIV vaccine could substantially impact the epidemic. However, risk compensation (RC), or post-vaccination increase in risk behavior, could present a major challenge. The methodology used in previous studies of risk compensation has been almost exclusively individual-level in focus, and has not explored how increased risk behavior could affect the connectivity of risk networks.

HIV vaccine acceptability among high-risk drug users in Appalachia: a cross-sectional study.

Background: A vaccine could substantially impact the HIV epidemic, but inadequate uptake is a serious concern. Unfortunately, people who use drugs, particularly those residing in rural communities, have been underrepresented in previous research on HIV vaccine acceptability. This study examined HIV vaccine acceptability among high-risk drug users in a rural community in the United States.

Drug users' willingness to encourage social, sexual, and drug network members to receive an HIV vaccine: a social network analysis.

This study examined feasibility of peer-based promotion of HIV vaccination and dyadic correlates to vaccine encouragement in risk- and non-risk networks of drug users (n = 433) in the US. Data were collected on HIV vaccine attitudes, risk compensation intentions, likelihood of encouraging vaccination, and recent (past 6 months) risk (i.e.

Smoke and Mirrors: The Perceived Benefits of Continued Tobacco use Among Current Smokers.

Despite 50+ years of public health efforts to reduce smoking rates in the United States, approximately one-fifth of the adults living in this country continue to smoke cigarettes. Previous studies have examined smokers' risk perceptions of cigarette smoking, as well as the perceived benefits of quitting smoking. Less research has focused on the perceived benefits of smoking among current cigarette smokers.

Early adolescent pregnancy increases risk of incident HIV infection in the Eastern Cape, South Africa: a longitudinal study.

Introduction: Adolescents having unprotected heterosexual intercourse are at risk of HIV infection and unwanted pregnancy. However, there is little evidence to indicate whether pregnancy in early adolescence increases the risk of subsequent HIV infection. In this paper, we tested the hypothesis that adolescent pregnancy (aged 15 or younger) increases the risk of incident HIV infection in young South African women.

Neighbourhood structural characteristics and crack cocaine use: exploring the impact of perceived neighbourhood disorder on use among African Americans.

Background: Crack cocaine use and associated negative social and health consequences remain a significant public health problem. Research that expands beyond the individual by considering the environmental context as a determinant of cocaine use is growing. The main objectives of this paper are to examine the effects of perceived neighbourhood disorder as an independent correlate of the frequency of recent crack cocaine use and whether its impact is mediated by use-related practices and social context of use among an African American adult sample in Atlanta (GA).
