Inorganic arsenic (iAs) exposure is detrimental to birth outcome. We lack information regarding the potential for iAs metabolism to affect fetal growth. Our pilot study evaluated postpartum Romanian women with known birth weight outcome for differences in iAs metabolism. Subjects were chronically exposed to low-to-moderate drinking water iAs. We analyzed well water, arsenic metabolites in urine, and toenail arsenic. Urine iAs and metabolites, toenail iAs, and secondary methylation efficiency increased as an effect of exposure (p<0.001). Urine iAs and metabolites showed a significant interaction effect between exposure and birth weight. Moderately exposed women with low compared to normal birth weight outcome had greater metabolite excretion (p<0.03); 67% with low compared to 10% with normal birth weight outcome presented urine iAs >9 μg/L (p=0.019). Metabolic partitioning of iAs toward excretion may impair fetal growth. Prospective studies on iAs excretion before and during pregnancy may provide a biomarker for poor fetal growth risk.

The role of craving in opioid use disorder (OUD) has been well established with respect to heroin but less so with prescription opioids. This pilot study, conducted in 18 treatment-seeking patients with prescription OUD and 18 healthy volunteers, assessed spontaneous (in the moment) and cue-induced craving and their relationship to depression and anxiety. Patients (vs.

Puberty is a particularly vulnerable time for individuals with autism spectrum disorder (ASD) during which baseline challenges are exacerbated, functioning often deteriorates, and additional barriers emerge. Specific concerns include increased vulnerability, decreased safety, and increased mood and behavioral disturbances. Youth with ASD need guidance and explicit instruction/skill development on topics such as hygiene/self-care, appropriate sexual activity, and menstruation management.

Introduction: Sedation is often required during flexible fiberoptic bronchoscopy (FFB) to ensure patient comfort and the success of the procedure. The choice of sedative agents may differ between anesthesiologists and pulmonologists. This pilot study aimed to investigate the current pre-procedure preparation, monitoring, premedication and sedation practices for FFB in Türkiye, focusing on the preferences and practices of pulmonologists.

This study aimed to examine whether an acceptance and commitment therapy (ACT)-based parenting program, incorporating topics of emotional and stress management, parenting skills training, autism-related education, and self-care learning, could be successfully implemented, well-received, and beneficial for parents of children with autism. We randomly assigned 40 parents to either participate in the eight-session ACT-based parenting program or receive usual care only. The program was found to be feasible, with many parents willing to participate and complete the sessions.

Norovirus (NoV) infection is a leading cause of gastroenteritis and poses global health threats, with increasing incidence reported in immunocompromised individuals, which is further exacerbated by the globalization of the food industry. Eumelanin has demonstrated its potential in antiviral treatments, but its role in preventing viral infections remains underexplored. Therefore, in this study, we investigated the antiviral properties and potential mechanisms of self-assembled eumelanin nanoparticles (EmNPs) against Tulane virus (TuV), a surrogate with a similar infection mechanism to NoVs.
