Evidence-based teaching is a highly complex skill, requiring repeated cycles of deliberate practice and feedback to master. Despite existing well-characterized frameworks for practice-based training in K-12 teacher education, the major principles of these frameworks have not yet been transferred to instructor development in higher educational contexts, including training of graduate teaching assistants (GTAs). We sought to determine whether a practice-based training program could help GTAs learn and use evidence-based teaching methods in their classrooms...

OBJECTIVES: External laryngeal manipulation is a commonly used maneuver to improve visualization of the glottis during tracheal intubation in children. However, the effectiveness to improve tracheal intubation attempt success rate in the nonanesthesia setting is not clear. The study objective was to evaluate the association between external laryngeal manipulation use and initial tracheal intubation attempt success in PICUs. DESIGN: A retrospective observational study using a multicenter emergency airway quality improvement registry...

Coal power generation is expanding rapidly in India and other developing countries. In addition to consequences for climate change, present-day health externalities may also substantially increase the social cost of coal. Health consequences of air pollution have proven important in studies of developed countries, but, despite clear importance, similarly well-identified estimates are less available for developing countries, and no estimates exist for the important case of coal in India. We exploit panel data on Indian households, matched to local changes in exposure to coal plants...

African-American women report higher levels of chronic conditions and church attendance relative to the overall US population. Therefore, efforts have increased over the past decade to design church-based health promotion programs. The present study compared changes in religiosity, religious social support and general social support across time within a church-based physical activity study. In a clustered randomized controlled trial, 31 churches and ∼15 African-American women per church were recruited to participate...

Evaluation of functional and bioactive compounds of Asparagus officinalis L. growing in conventional and organic greenhouse and conventional open - field farming was the aim of this research. Polyphenols in cladodes grown conventionally were higher than organic. Flavonoids and carotenoids were the highest in cladodes in open field. Organic spears were richer in total phenolics (+6.9% and +19.1%) and flavonoids (+4.7% and 16.8%) and showed higher in vitro averages of antioxidant activities by three radical scavenging assays (+12...

Exercise represents an important lifestyle factor in all human ages when felt in harmony with other psycho-physical and environmental variables that affect individual life (e. g. quality of interest, affections, environment, diet and food). Consequently, in addition to the training level, the amount, intensity and modality of exercise (ana-/aerobic, isometric/isotonic), need to be personalized, considering the underlying diseases, which may benefit from it or worsening.Greek mythology gives us good examples of the exercise concept's evolution...

Sexual and gender minority Hispanics/Latinxs (henceforth: Latinxs) continue to be disproportionately impacted by HIV/AIDS in the U.S. Pre-exposure prophylaxis (PrEP) is a biomedical prevention approach which holds significant promise for at risk and vulnerable populations. We discuss barriers and facilitators to uptake of PrEP among sexual and gender minority Latinxs living in the U.S. through an ecosocial lens that takes into account structural, community, and individual contexts. The impact of immigration status on PrEP uptake emerges as a major and recurrent theme that must be understood and addressed by HIV prevention programs aiming to promote an inclusive strategy for sexual and gender minority Latinxs living in the U...

INTRODUCTION: Epithelial-mesenchymal-transition (EMT) has been previously identified as a contributor to prostate cancer progression to metastasis and therapeutic resistance to antiandrogens and radiotherapy. In this study we conducted a retrospective analysis to investigate the significance of radiation-induced EMT and consequential changes to the tumor microenvironment in biochemical recurrence and response to radiotherapy in prostate cancer patients. METHODS: Expression profiling and localization for EMT effectors, E-Cadherin, N-Cadherin, β-catenin and Vimentin was assessed in human prostate tumor specimens pre- and post-radiotherapy and correlated with biochemical recurrence...

The invasion of Indo-Pacific lionfish is one of the most pressing concerns in the context of coral reef conservation throughout the Caribbean. Invasive lionfish threaten Caribbean fish communities by feeding on a wide range of native prey species, some of which have high ecological and economic value. In Roatan (Honduras) a local non-governmental organisation (i.e. Roatan Marine Park) trains residents and tourists in the use of spears to remove invasive lionfish. Here, we assess the effectiveness of local removal efforts in reducing lionfish populations...

Objective: National health organizations and expert committees have issued recommendations for health behaviors related to obesity risk. Behavioral and family-based weight management interventions for preschoolers often target improving adherence to these recommendations, but it is unknown how the health behaviors of preschoolers with obesity enrolled in weight control treatments (WCTs) compare with these guidelines. In this study, the dietary intake, activity, and sleep behaviors of preschoolers with obesity enrolled in a family-based behavioral WCT are described and compared with national health behavior recommendations...

There is a pressing need to apply stability and resilience theory to environmental management to restore degraded ecosystems effectively and to mitigate the effects of impending environmental change. Lakes represent excellent model case studies in this respect and have been used widely to demonstrate theories of ecological stability and resilience that are needed to underpin preventative management approaches. However, we argue that this approach is not yet fully developed because the pursuit of empirical evidence to underpin such theoretically grounded management continues in the absence of an objective probability framework...

Phishing risk is a growing area of concern for corporations, governments, and individuals. Given the evidence that users vary widely in their vulnerability to phishing attacks, we demonstrate an approach for assessing the benefits and costs of interventions that target the most vulnerable users. Our approach uses Monte Carlo simulation to (1) identify which users were most vulnerable, in signal detection theory terms; (2) assess the proportion of system-level risk attributable to the most vulnerable users; (3) estimate the monetary benefit and cost of behavioral interventions targeting different vulnerability levels; and (4) evaluate the sensitivity of these results to whether the attacks involve random or spear phishing...

Staphylococcus aureus pathogenicity islands (SaPIs), such as SaPI1, exploit specific helper bacteriophages, like 80α, for their high frequency mobilization, a process termed 'molecular piracy'. SaPI1 redirects the helper's assembly pathway to form small capsids that can only accommodate the smaller SaPI1 genome, but not a complete phage genome. SaPI1 encodes two proteins, CpmA and CpmB, that are responsible for this size redirection. We have determined the structures of the 80α and SaPI1 procapsids to near-atomic resolution by cryo-electron microscopy, and show that CpmB competes with the 80α scaffolding protein (SP) for a binding site on the capsid protein (CP), and works by altering the angle between capsomers...

To document the current perfusion workforce status and to anticipate the future demands of an ever-changing perfusion workplace environment, a valid survey is needed to help guide the future of the perfusion workforce. The American Board of Cardiovascular Perfusion (ABCP) sponsored a survey of Certified Clinical Perfusionist (CCP) demographic and clinical trends that was linked electronically to the 2015-2016 ABCP online recertification process. Of 3,875 eligible CCP's, 3,056 (78.9%) responded to the survey...

Agriculture is a hazardous industry, yet there are few regulations on the ages at which children may engage in farm work. Local agricultural market producers (LAMP) are a growing subset of farmers within "sustainable agriculture" who engage in direct-to-consumer and direct-to-retailer enterprises. This study explores the occupational health and safety perceptions of parents and children for children who work on their families' LAMP farms. In-depth interviews were conducted with 12 parent-child dyads from LAMP farms in Illinois and North Carolina...

The nasolabial turnover flap was first described by Spear et al in 1987 for the coverage of full thickness defects of the lateral ala. It offered a single-stage repair that recreated the internal nasal lining, the external nasal valve, and the rounded contour of the ala without requiring a cartilage graft. A frequently encountered problem with the execution of Spear's original design is elevation of the ipsilateral commissure of the adjacent lip due to its broad proximal pedicle. Here, the authors describe a fusiform-type design with a proximal, superiorly tapered apex that relies on anteriorly coursing perforators from the underlying angular artery...

BACKGROUND: Numerous techniques for the surgical management of lambdoidal synostosis have been previously described; however, no best practice technique currently exists. Surgical procedures range from complete posterior calvarial reconstruction to distraction osteogenesis techniques. Our primary purpose is to describe a novel approach to correct unilateral or bilateral lambdoidal synostosis. METHODS: A retrospective review was performed on a single surgeon's experience with craniosynostosis (1994-2014)...

Excess body weight is a poor prognostic factor in women with early breast cancer, but the effect of weight loss on the risk of breast cancer recurrence and mortality in women who are overweight or obese at the time of breast cancer diagnosis has not been evaluated. The Alliance for Clinical Trials in Oncology Breast Cancer Weight Loss trial, also known as A011401, is testing the impact of a telephone-based weight loss program on invasive disease-free survival in 3136 women with a body mass index ≥27 kg/m(2) who have recently been diagnosed with stage II-III, HER-2 negative breast cancer...
