BACKGROUND: Female sex workers (FSWs) in Bangladesh remain at elevated risk of sexually transmitted infections (STIs) although the human immunodeficiency virus (HIV) prevalence among them is low. Recent information on the burden and etiological diagnosis of STIs among them has been lacking. This study examines prevalence and risk behaviors of selected STIs among FSWs in Dhaka in 2014. METHODS: Between August and October 2014, a cross-sectional study was conducted among street-based and residence-based FSWs receiving HIV prevention services at 24 drop in centers in Dhaka...

INTRODUCTION: Many developing countries are facing rise in firearm injury cases owing to communal and ethnic clashes, political violence, armed robberies and suicide causing huge economic loss to society. On the basis of intention, injuries can be categorized as intentional and unintentional or accidental injuries. Intentional injuries will include suicidal, homicidal and assault related injuries. AIM: This study was undertaken to document the trends and patterns associated with intentional firearm injuries in order to suggest ways to curb the emerging trends...

Explanations for the evolution of delayed maturity usually invoke trade-offs mediated by growth, but processes of reproductive maturation continue long after growth has ceased. Here, we tested whether sexual selection shapes the rate of posteclosion maturation in the fruit fly Drosophila melanogaster. We found that populations maintained for more than 100 generations under a short generation time and polygamous mating system evolved faster posteclosion maturation and faster egg-to-adult development of males, when compared to populations kept under short generations and randomized monogamy that eliminated sexual selection...

Central to the basis of ecological immunology are the ideas of costs and trade-offs between immunity and life history traits. As a physical barrier, the insect cuticle provides a key resistance trait, and Tenebrio molitor shows phenotypic variation in cuticular colour that correlates with resistance to the entomopathogenic fungus Metarhizium anisopliae. Here we first examined whether there is a relationship between cuticular colour variation and two aspects of cuticular architecture that we hypothesised may influence resistance to fungal invasion through the cuticle: its thickness and its porosity...

The decision to provide parental care is often associated with trade-offs, because resources allocated to parental care typically cannot be invested in self-maintenance or mating. In most animals, females provide more parental care than males, but the reason for this pattern is still debated in evolutionary ecology. To better understand sex differences in parental care and its consequences, we need to study closely related species where the sexes differ in offspring care. We investigated parental care in relation to offspring growth in two closely related coucal species that fundamentally differ in sex roles and parental care, but live in the same food-rich habitat with a benign climate and have a similar breeding phenology...

OBJECTIVE: To determine whether lung function trajectories after 9/11/2001 (9/11) differed by sex or race/ethnicity in World Trade Center-exposed Fire Department of the City of New York emergency medical service (EMS) workers. METHOD: Serial cross-sectional study of pulmonary function tests (PFTs) taken between 9/11 and 9/10/2015. We used data from routine PFTs (forced expiratory volume in 1 s (FEV1) and FEV1% predicted), conducted at 12-18 month intervals. FEV1 and FEV1% predicted were assessed over time, stratified by sex, and race/ethnicity...

Prior research has found that pimps use both non-coercive and coercive management styles across and within market segments of the illicit sex trade. The current study is the first to examine the socialization processes underlying variation in the self-reported coerciveness of pimps. This study begins to fill a void in the almost non-existent research on pimps who are actively managing Internet-solicited sex workers, and adds to the sparse research on pimps' coerciveness. We extend Anderson's concepts of "street code" families, where respect is acquired through displaying physical violence and toughness, and "decent" families, where middle class values of avoiding unnecessary aggression and complying with the law prevail, to understand variation in the degree of coerciveness that pimps utilize toward sex workers...

The present study investigated the use of a tablet computer to assess figure-tracing skills and their relationships with psychological (visual-perceptual processes, cognitive processes, handwriting skills) and physiological (body mass index, isometric strength of arms) parameters with school-children of second (7-8-year-olds) and fourth (9-10-year-olds) grades. We were also interested in gender differences. The task required tracing of geometric figures on a template, shown on a tablet screen in light gray, for the segments that make up the target figure, one at a time...

We have carried out animal toxicity tests of chemicals for a chemical safety program implemented by the Ministry of Economy, Trade, and Industry of Japan. Here, we tested 1-tert-butoxy-4-chlorobenzene in a combined repeat-dose and developmental and reproductive toxicity test. The test chemical was administered daily by gavage to 9-week-old Crl:CD (SD) rats at doses of 0, 20, 100, and 500  mg/kg/d. Males were treated for 42 d beginning 14 d before mating. Females were treated from 14 d before mating to day 4 of lactation...

In nature, the intensity of mate choice (i.e., choosiness) is highly variable within and between sexes. Despite growing empirical evidence of male and/or mutual mate choice, theoretical investigations of the joint evolution of female and male choosiness are few. In addition, previous approaches have often assumed an absence of trade-off between the direct benefits per mating and the lower mating rate that results from being choosy. Here we model the joint evolution of female and male choosiness when it is solely ruled by this fundamental trade-off...

The transfer of acquired and specific immunity against previously encountered bacteria from mothers to offspring boosts the immune response of the next generation and supports the development of a successful pathogen defense. While most studies claim that the transfer of immunity is a maternal trait, in the sex-role-reversed pipefish Syngnathus typhle, fathers nurse the embryos over a placenta-like structure, which opens the door for additional paternal immune priming. We examined the potential and persistence of bacteria-type-specific parental immune priming in the pipefish S...

Age and sex patterns of migration are essential for understanding drivers of population change and heterogeneity of migrant groups. We develop a hierarchical Bayesian model to estimate such patterns for international migration in the European Union and European Free Trade Association from 2002 to 2008, which was a period of time when the number of members expanded from 19 to 31 countries. Our model corrects for the inadequacies and inconsistencies in the available data and estimates the missing patterns. The posterior distributions of the age and sex profiles are then combined with a matrix of origin-destination flows, resulting in a synthetic database with measures of uncertainty for migration flows and other model parameters...

BACKGROUND: Although sleep is considered an essential part of individuals' lives, there are no previous studies analysing how sleep duration affects the levels of life satisfaction reported by males and females with disabilities. OBJECTIVE/HYPOTHESIS: To analyse and compare the impact of hours of sleep on life satisfaction scores reported by people without and with disabilities (stratified by sex) in Germany. METHODS: Using data taken from the German Socio-Economic Panel for the period 2008-2013, we estimate life satisfaction equations for males and females (running a fixed-effects model) which include a set of variables measuring the number of sleep hours on workdays and weekends...

Humans stand out among non-aquatic mammals by having both an extremely large brain and a relatively large amount of body fat. To understand the evolution of this human peculiarity we report a phylogenetic comparative study of 120 mammalian species, including 30 primates, using seasonal variation in adult body mass as a proxy of the tendency to store fat. Species that rely on storing fat to survive lean periods are expected to be less active because of higher costs of locomotion and have increased predation risk due to reduced agility...

OBJECTIVES: Latina women are disproportionately affected by HIV in the US, and account for 30% of all HIV infections in Miami-Dade County, Florida. The main risk for Latina women is heterosexual contact. Little is known about the relational and cultural factors that may impact women's HIV risk perception. This study aims to describe Latina women's perception of their HIV risk within a relational, cultural, and linguistic context. DESIGN: Eight focus groups of Latina women (n = 28), four English speaking groups and four Spanish speaking groups, were conducted between December 2013 and May 2014...

Utilizing a newly released cognitive Polygenic Score (PGS) from Wave IV of Add Health (n = 1,886), structural equation models (SEMs) examining the relationship between PGS and fertility (which is approximately 50% complete in the present sample), employing measures of verbal IQ and educational attainment as potential mediators, were estimated. The results of indirect pathway models revealed that verbal IQ mediates the positive relationship between PGS and educational attainment, and educational attainment in turn mediates the negative relationship between verbal IQ and a latent fertility measure...

Clinical and experimental evidence shows that estrogens affect immunity in mammals. Less is known about this interaction in the evolutionary older, non-mammalian, vertebrates. Fish form an excellent model to identify evolutionary conserved neuroendocrine-immune interactions: i) they are the earliest vertebrates with fully developed innate and adaptive immunity, ii) immune and endocrine parameters vary with season iii) physiology is constantly disrupted by increasing contamination of the aquatic environment...
