Context-specific typologies of female sex workers (FSWs) are essential for the design of HIV intervention programming. This study develops a novel FSW typology for the analysis of transactional sex risk in rural and urban settings in Indonesia. Mixed methods include a survey of rural and urban FSWs (n=310), in-depth in…

The average potency of illicit marijuana in the USA has increased substantially over the past four decades, and observers have suggested a number of likely reasons for this. One set of hypotheses points to a market that has evolved from foreign to domestic sources of supply, and to continuing advances in sophisticated…

We conducted a randomized, controlled, double-blind, prospective study to evaluate the effect of intraoperative bupivacaine injection on postoperative pain control following Bovie cautery-assisted tonsillectomy in 26 adults. Sixteen patients were injected with 10 ml of 0.5% bupivacaine with 1:200,000 epinephrine, and 1…

In 1991, Bernadette Stringer, a long time BC Nurses' Union health and safety representative, learned about the death of a 48 year old Victoria, B.C., OR nurse who had sustained a hepatitis C contaminated needlestick. This incident led to a study evaluating the hands-free technique's ability to decrease the risk of perc…

This study assesses the frequency that users of illicit drugs display unprofessional behaviors in an employment setting. This research was conducted in the therapeutic workplace, a model employment-based treatment program for chronically unemployed adults with long histories of illicit drug use in 2003. Fifty-three une…

BACKGROUND: Allergic rhinitis is considered a risk factor for bronchial asthma. It therefore seems essential to identify patients threatened with this disease in whom no disturbing bronchial symptoms have occurred. The study's aim was to evaluate the incidence of nonspecific bronchial hyperactivity based on exercise re…

OBJECTIVES: Defining what makes an exceptional teacher is challenging. This study's objectives were to identify teaching attributes that residents and faculty value most and to determine whether the opinions of residents and faculty differed. METHODS: A list of 15 teaching attributes was distributed to residents and f…

Discussion abounds in the literature as to whether aphasia is a deficit of linguistic competence or linguistic performance and, if it is a performance deficit, what are its precise mechanisms. Considerable evidence suggests that alteration of nonlinguistic factors can affect language performance in aphasia, a finding t…

Problems arise when clinical instructors are placed in situations for which they are ill prepared. Teaching occurs in settings where patient safety and quality must be ensured. Trigger films are 2- to 4-minute vignettes simulating real-life situations that finish abruptly, stimulating participants to analyze situations…

Children morbimortality rates in Brazil provide some indications about the life patterns of certain social groups, considered as risk groups, due to their vulnerability to a number of health impairments, but they do no display a clear picture of their quality of life. The present study aims to describe the steps undert…

In this study, the concentrations of trace metals were examined in commercially important fish,andfrom Osu reservoir. These were with a view to providing baseline information on the levels of heavy metals and its associated risks to human health through fish consumption.

This study compared survival outcomes between neoadjuvant chemotherapy (NACT) and adjuvant chemotherapy (ACT) in patients with locally advanced, hormone receptor-positive, HER2-negative invasive lobular carcinoma (ILC). We conducted a retrospective cohort study using Surveillance, Epidemiology, and End Results (SEER) d…

We have previously shown that Achilles tendon length is related to walking economy on the flat, presumably because of increased stretch-shortening cycle elastic energy savings. In addition, greater walking economy in African American (AA) women compared to European American (EA) women is explained by longer Achilles te…

Understanding the role of people in occupational accidents is very difficult. It is always assumed that people perform the behaviour that feels right to them. This study's main topic is the relationship between values, which form the basis of human behaviour, and safety motivation, fatalistic tendencies, risk perceptio…

Significant challenges confronting China include reducing carbon emissions, dealing with the resulting problems, and meeting various requirements for long-term economic growth. As a result, the shift in industrial structure best reflects how human society utilizes resources and impacts the environment. To meet China's…

Methods to assess environmental exposure to hazardous chemicals have primarily focused on quantification of individual chemicals, although chemicals often occur in mixtures, presenting challenges to the traditional risk characterization framework. Sampling sites in a defined geographic region provide an opportunity to…

Excess dietary sugar intake increases the risk of unhealthy weight gain, an important cardiometabolic risk factor in children. To further our understanding of this relationship, we performed a narrative review using two approaches. First, research examining dietary sugar intake, its associations with cardiometabolic he…
