BACKGROUND: Recent trends have witnessed the global growth of unconventional oil and gas (UOG) production. Epidemiologic studies have suggested associations between proximity to UOG operations with increased adverse birth outcomes and cancer, though specific potential etiologic agents have not yet been identified. To perform effective risk assessment of chemicals used in UOG production, the first step of hazard identification followed by prioritization specifically for reproductive toxicity, carcinogenicity and mutagenicity is crucial in an evidence-based risk assessment approach...

Mycotoxins are secondary fungi metabolites that induce acute and chronic toxic effects in humans and animals. Simultaneous contamination of cereal-based products by multiple mycotoxins has been increasingly reported, including in food products usually consumed by children. Although some previous authors assessed the health risk of children exposed to multiple mycotoxins, scarce data are available on the risk associated with the ingestion of multiple mycotoxins through different food products. MYCOMIX, a national funded project, intended to contribute to fill this gap...

The ill-defined term "energy drink" includes a disparate group of products (beverages, shots, concentrates, and workout powders) having large differences in caffeine content and concentration and intended use. Hence, inaccurate conclusions may be drawn when describing adverse events associated with "energy drinks". The FDA is considering new regulation of these products but product specificity is needed to evaluate safety. To help address this, we queried Texas Poison Center Network data for single substance exposures to "energy drinks" from 2010 to 2014, then analyzed adverse events by product type...

Malnutrition is highly prevalent in geriatric patients and is associated with an increased risk of death. In addition, delirium is a common condition of the older hospitalized patients. As brain has a high nutritional requirement, malnutrition may play an important role in cognitive dysfunction including the development of delirium. This study investigated the association between delirium and malnutrition in frail older patients and the effects on adverse outcomes. It was found that 75% of the patients with delirium suffered from malnutrition indicating that malnutrition contributes to the development of delirium in older hospitalized patients...

Although accurate risk appraisals are mandatory to provide effective treatment to juveniles who have sexually offended (JSOs), the current knowledge on the validity of risk assessment instruments for JSOs is inconclusive. We compared the predictive validities of the Juvenile Sex Offender Assessment Protocol II (J-SOAP II), the Estimate of Risk of Adolescent Sexual Offense Recidivism (ERASOR), and the Violence Risk Appraisal Guide-Revised (VRAG-R) scores concerning sexual, nonsexual-violent, and general criminal recidivism (based on both official and nonregistered reoffenses) in a consecutive sample of 597 male JSOs (Mage = 14...

The present study examined the associations of familial expressed emotion (EE) with clinical and personal recovery among patients with psychiatric disorders, as well as the potential mechanisms underlying these associations. Guided by the content-process theory of self-stigma, we hypothesized that EE would be negatively associated with clinical and personal recovery and that these associations would be mediated by self-stigma content and process. A total of 311 patients with psychiatric disorders completed questionnaires on their perceptions of EE, self-stigma, and recovery...

Chronic kidney disease (CKD) is a major risk factor for cardiovascular disease but is often associated with other risks such as diabetes and hypertension and can be both a cause and an effect of cardiovascular disease. Although epidemiologic data of an independent association of reduced glomerular filtration rate with cardiovascular risk are strong, causative mechanisms are unclear. Living kidney donors provide a useful model for assessing the "pure" effects of reduced kidney function on the cardiovascular system...

BACKGROUND: Simulation-based education (SBE) has emerged as an essential modality for health professions education. One of the central tenants of effective SBE is reflective practice, typically guided by a facilitated debriefing. The debriefing conversation has the possibility of becoming a difficult conversation based on learner and situation-related factors. Difficult debriefing situations may threaten the learning environment, thus requiring an appreciation and understanding of the various ways that learners may react adversely to simulation and debriefing...
