INTRODUCTION: Reproductive health of adolescent girls is crucial as it determines the health of future generations. School girls when experiencing menarche find themselves in a setting without water, toilets or a supportive female teacher to explain the changes happening in their body. An important concern for adolescent girls is to have adequate, correct knowledge along with facilities and the cultural environment to manage menstruation hygienically and with dignity. Hence, the present study was done to assess knowledge and practices about menstruation in adolescent school girls of an urban slum...

INTRODUCTION: Simulation-based clinical education often aims to replicate varying aspects of real clinical practice. It is unknown whether learners' stress levels in simulation are comparable with those in clinical practice. The current study compared acute stress markers during simulation-based clinical education with that experienced in situ in a hospital-based environment. METHODS: Undergraduate physiotherapy students' (n = 33) acute stress responses [visual analog scales of stress and anxiety, continuous heart rate (HR), and saliva cortisol] were assessed during matched patient encounters in simulation-based laboratories using standardized patients and during hospital clinical placements with real patients...

BACKGROUND: Health care-associated infection outbreaks have occurred in outpatient settings due to lapses in infection prevention. However, little is known about the overall infection prevention status in outpatient environments. METHODS: A cross-sectional design was employed to assess infection prevention policies and practices at 15 outpatient sites across New Mexico in 2014 during a medical student outpatient rotation. A standardized infection prevention checklist was completed via staff interview; observations of injection safety practices and hand hygiene behavior were conducted...

The household is a potential source of opportunistic pathogens to humans, a particularly critical issue for immunodeficient individuals. An important human-microbe interface is the biofilm that develops on showerhead surfaces. Once microbe-laden biofilms become aerosolized, they can potentially be inhaled into the lungs. Understanding how quickly a new showerhead becomes colonized would provide useful information to minimize exposure to potentially pathogenic environmental microbes. High school scientists sampled the inner surfaces of pre-existing and newly fitted showerheads monthly over a nine-month period and applied standard microbiologic culture techniques to qualitatively assess microbial growth...

We investigated whether distance estimation accuracy over open water is influenced by the viewing direction of the observer. Twenty-two healthy students (9 male, 13 female) made 10 distance estimates ranging between 50 and 950 m actual distance in 2 viewing conditions: (1) from shore to boat and (2) from boat to shore. There were no consistent differences in estimation accuracy between viewing directions. The group data revealed a general tendency to underestimate actual distances (74%), but there was considerable interindividual variance (mean error of 74% ± 27%, range = 31% to 145%)...

INTRODUCTION: Consumption of sugar-sweetened beverages (SSBs) such as sodas, fruit-flavored drinks, and sports drinks is a major contributor to childhood obesity. One strategy to reduce children's SSB consumption has been to restrict the sale of SSBs in schools. However, such policies may not sufficiently curb students' SSB intake, because students can obtain SSBs elsewhere, including from stores located on their school commute. Little is known about students' purchases of beverages during the school commute or about whether this purchasing behavior is related to in-school SSB consumption...

Advective exchange between the pore space of sediments and the overlying water column, called hyporheic exchange in fluvial environments, drives solute transport in rivers and many important biogeochemical processes. To improve understanding of these processes through visual demonstration, we created a hyporheic flow simulation in the multi-agent computer modeling platform NetLogo. The simulation shows virtual tracer flowing through a streambed covered with two-dimensional bedforms. Sediment, flow, and bedform characteristics are used as input variables for the model...

Soil microbial communities play a critical role in nutrient transformation and storage in all ecosystems. Quantifying the seasonal and long-term temporal extent of genetic and functional variation of soil microorganisms in response to biotic and abiotic changes within and across ecosystems will inform our understanding of the effect of climate change on these processes. We examined spatial and seasonal variation in microbial communities based on 16S rRNA gene sequencing and phospholipid fatty acid (PLFA) composition across four biomes: a tropical broadleaf forest (Hawaii), taiga (Alaska), semiarid grassland-shrubland (Utah), and a subtropical coniferous forest (Florida)...

There is a need to better understand the types of natural environments that different individuals and groups find mental health promoting. In this exploratory qualitative study, twelve university students were invited to photographically document a natural place that they considered beneficial to their mental health. Thematic analysis of photographs and follow-up in-depth interviews revealed that students prefer natural places that are familiar, contain a variety of natural elements (especially mature trees and some form of water), and are separate from the context of everyday campus life (distanced from both the built and social campus environment)...
