This work aimed at evaluating the toxic effects of in ovo exposure to phenobarbital (PB) and unveiling the mode of action by transcriptome analysis in the embryonic liver of a model avian species, chicken (Gallus gallus). Embryos were initially treated with saline or 1 μg PB /g egg at Hamburger Hamilton Stage (HHS) 1 (1st day), followed by 20 days of incubation to HHS 46. At 21st day, chicks that pipped successfully were euthanized and dissected for assessing the PB caused effects on phenotypes and the liver transcriptome in both genders...

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...

Although childhood maltreatment is associated with long-term impairment, some children function well despite this adversity. This study aimed to identify the key protective factors for good educational attainment and positive emotional health in adolescents who experienced maltreatment in early childhood. Data were analyzed from the Avon Longitudinal Study of Parents and Children, a large UK prospective cohort study. The sample was defined by maternally reported exposure to physical or emotional maltreatment by a parent prior to 5 years...

Depression is associated with alterations in hypothalamic-pituitary-adrenal (HPA) axis activity. A proposed mechanism to explain these alterations are changes in DNA methylation levels, secondary to early life adversity (ELA), at stress-related genes. Two gene regions that have been implicated in the literature, the glucocorticoid receptor gene (NR3C1) exon 1F and the FKBP5 gene intron 7 were examined in 67 individuals (33 depressed patients and 34 controls). We investigated whether cortisol concentrations, evaluated in 25 depressed patients and 20 controls, and measures of ELA were associated with the degree of methylation at these candidate gene regions...

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...

A number of drug-specific and host-related factors contribute to the development of drug-induced liver injury (DILI). Investigations focused on genetic susceptibility to DILI have advanced our understanding of the pathogenesis of this rare, yet potentially life-threatening adverse reaction. Candidate gene studies involving well-characterized patients with DILI and drug-exposed controls have identified single nucleotide polymorphisms (SNPs) affecting the metabolism and clearance of specific drugs and hence, influencing individual's susceptibility to DILI...

BACKGROUND: Women with a gynecologic cancer tend to be older, obese, and postmenopausal, characteristics that are associated with an increased risk for obstructive sleep apnea. However, there is limited investigation regarding the condition's prevalence in this population or its impact on postoperative outcomes. In other surgical populations, patients with obstructive sleep apnea have been observed to be at increased risk for adverse postoperative events. OBJECTIVES: To estimate the prevalence of obstructive sleep apnea among gynecologic oncology patients undergoing elective surgery and to investigate for a relationship between obstructive sleep apnea and postoperative outcomes...

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...
