Despite the high HIV incidence and prevalence among black men who have sex with men (BMSM), little research has examined partner characteristics, partner seeking venue, sexual position, substance use, and sexual risk behavior at the sex event-level among BMSM. Using the baseline data from a multi-site study of 807 BMSM stratified by their HIV status, the goal of this study was to conduct a detailed event-level analysis of 1577 male anal sex events to assess the factors associated with condomless anal intercourse (CLAI) with a HIV-discordant or HIV status-unknown partner...

The increasing utilization of a gonadotropin-releasing hormone agonist ovulation trigger and the widespread use of artificial cycles for the transfer of frozen-thawed or donated embryos has renewed interest in the luteal phase in assisted reproductive technology. The "luteal phase defect" phenomenon is now understood as a continuum: there is less impairment with milder stimulation than with more intense ovarian stimulation, and less impairment after controlled ovarian stimulation and human chorionic gonadotropin ovulation triggering than after gonadotropin-releasing hormone agonist ovulation triggering, the latter being associated with rapid luteolysis...

Chemical signals are one means by which many insect species communicate. Differences in the combination of surface chemicals called cuticular hydrocarbons (CHCs) can influence mating behavior and affect reproductive isolation between species. Genes influencing three CHC compounds have been identified in Drosophila melanogaster. However, the genetic basis of other CHC compounds, whether these genes affect species differences in CHCs, and the genes' resulting effect on interspecies mating, remains unknown. We used fine-scale deficiency mapping of the third chromosome to identify 43 genomic regions that influence production of CHCs in both D...

There is increasing evidence to suggest that leaders need to use a combination of leader behaviors to successfully improve safety, including both transformational and transactional styles, but there has been limited testing of this idea. We developed a leadership intervention, based on supervisor training in both transformational and active transactional behaviors, and implemented it with supervisors at a UK-based chemical processing company. The study found that the supervisory training intervention led to significant improvements in perceived employee safety climate, over an eight-week period, relative to the comparison group...

BACKGROUND: A large body of research has investigated the rise of injection drug use and HIV transmission in Tijuana and Ciudad Juarez (CJ). However, little is known about the dynamics of injecting in Hermosillo. This study compares drug-related behaviors and risk environment for HIV of people who inject drugs (PWID) across Tijuana, CJ, and Hermosillo to identify factors that could explain differences in HIV prevalence. METHODS: Data from Tijuana belong to a prospective study (El Cuete IV)...

OBJECTIVES: to evaluate the prevalence of acid burns among asylum seekers hosted in an initial reception centre and to evaluate if the prevalence is reduced after the introduction of the European Union (EU) regulation No. 29 (14th September 2016) that indirectly reduced the permanence time of the subjects on board of boats. DESIGN: cross-sectional study. SETTING AND PARTICIPANTS: 10,627 asylum seekers hosted in the centre for initial reception of Piedmont and Valle d'Aosta Regions (Northern Italy) between June 2016 and May 2017...

Emergency departments carry out an essential public service mission. They must be able to attend to anyone who arrives through their doors. Today, these departments are saturated, notably because they are having to respond to the insufficiency and lack of visibility of the community-based care provision. In this sense, users must be better informed of the options available to them upstream of the emergency departments. Finally, comprehensive reflection is necessary in order to improve the quality of patient reception in emergency departments...

The mission of an emergency department is to attend to any person arriving, at any time, whatever their condition, with the aim of treating them or transferring them to the most appropriate department. The approach often requires the provision of technical care meaning that relational care frequently takes a back seat. When the patient first arrives, the care is different, the patient-nurse interaction is essential. The role and the missions accorded to the triage nurse are fundamental in ensuring the patient receives quality care at this stage...

The number of patients attending emergency departments is constantly growing. They are fast becoming a place of primary care. Early assessment of patients must guarantee the safety of their care. The triage nurse uses a clinical examination and a triage chart to classify the patients. The reception of the patients by the triage nurse is professional. With tension often high in emergency departments, triage nurses play a role in defusing situations, which could constitute the next area of focus of their professionalization...

Scabies is a skin infestation with the mite Sarcoptes scabiei causing itch and rash and is a major risk factor for bacterial skin infections and severe complications. Here, we evaluated the treatment outcome of 2866 asylum seekers who received (preventive) scabies treatment before and during a scabies intervention programme (SIP) in the main reception centre in the Netherlands between January 2014 and March 2016. A SIP was introduced in the main national reception centre based on frequent observations of scabies and its complications amongst Eritrean and Ethiopian asylum seekers in the Netherlands...

Tree range shifts during geohistorical global change events provide a useful real-world model for how future changes in forest biomes may proceed. In North America, during the last deglaciation, the distributions of tree taxa varied significantly as regards the rate and direction of their responses for reasons that remain unclear. Local-scale processes such as establishment, growth, and resilience to environmental stress ultimately influence range dynamics. Despite the fact that interactions between trees and soil biota are known to influence local-scale processes profoundly, evidence linking below-ground interactions to distribution dynamics remains scarce...

In this study, methanolic extract of Saraca asoca bark was evaluated for its aphrodisiac potential using male and female Wistar albino rats. Male rats were dosed daily for 54 days at a dose of 100 mg/kg p.o. Sexual activity of male rats was assessed after 14, 28, 42 and 54 days of the study. Male rats were placed in a glass chamber lit with a dim red light (10W) followed by the introduction of sexually receptive female rats in a ratio of 1:1. Improvement in sexual behaviour of male rats was characterised by an increase in both mount frequency and intromission frequency and decrease or reduction in mount latency and intromission latency compared to normal control...

BACKGROUND: Internationally, overdose is the primary cause of death among people injecting drugs. However, since 2001, heroin-related overdose deaths in the United States (US) have risen sixfold, paralleled by a rise in the death rate attributed to synthetic opioids, particularly the fentanyls. This paper considers the adaptations some US heroin injectors are making to protect themselves from these risks. METHODS: Between 2015 and 2016, a team of ethnographers collected data through semi-structured interviews and observation captured in field notes and video recording of heroin preparation/consumption...

Early communication impairment is among the most-reported first concerns in parents of young children with autism spectrum disorder (ASD). Using a parent-report questionnaire, we derived trajectory groups for early language and gesture acquisition in siblings at high risk for ASD and in children at low risk, during their first 2 years of life. Developmental skills at 6 months were associated with trajectory group membership representing growth in receptive language and gestures. Behavioral symptoms also predicted gesture development...

Although reducing visual input to emphasize auditory cues is a common practice in pediatric auditory (re)habilitation, the extant literature offers minimal empirical evidence for whether unisensory auditory-only (AO) or multisensory audiovisual (AV) input is more beneficial to children with hearing loss for developing spoken language skills. Using an adapted alternating treatments single case research design, we evaluated the effectiveness and efficiency of a receptive word learning intervention with and without access to visual speechreading cues...

BACKGROUND: In all phases, patients are entitled to receive medical treatment according to medical specialist standards. This does not mean that patients necessarily have to be treated by a medical specialist. Operations performed by "beginners", e. g. assistant physicians, are permitted. However, there are increased liability risks, both for the specialist and the assistant physician. Furthermore, there are risks of criminal responsibility for causing bodily harm by negligence or negligent manslaughter...

Men who have sex with men (MSM), who have heterogeneous HIV-acquisition risks are not specifically targeted in Kenyan pre-exposure prophylaxis (PrEP) guidelines. We used data from an open cohort, which followed 753 initially HIV-negative MSM participants for more than 1378.5 person-years, to develop an empiric risk score for targeting PrEP delivery. Independent predictors of incident HIV-1 infection in this cohort were an age of 18-24 years, having only male sex partners, having receptive anal intercourse, having any unprotected sex, and having group sex...

BACKGROUND: Persons born outside the United States are more likely to be diagnosed with tuberculosis disease (TB) than native-born individuals. Foreign-born Latinos at risk of TB may be difficult to reach with public health interventions due to cultural and institutional barriers. Workplaces employing large concentrations of foreign-born Latinos may be useful locations for TB interventions targeting this high-risk population. METHOD: This study used a two-phase approach to investigate the feasibility of workplace TB interventions...

REVIEW

Signalling from cell-to-cell is fundamental for determining differentiation and patterning. This communication can occur between adjacent and distant cells. Extracellular vesicles (EVs) are membrane-based structures thought to facilitate the long-distance movement of signalling molecules. EVs have recently been found to allow the transport of two major developmental signalling pathways: Hedgehog and Wnt. These signalling molecules undergo crucial post-translational lipid modifications, which anchor them to membranes and impede their free release into the extracellular space...
