Article Synopsis
  • - Adolescent relationship abuse (ARA) is common among Latine youth, yet research on cultural and structural factors affecting their experiences is scarce, particularly regarding the role of parental influence.
  • - This study explored the connections between acculturation, discrimination, and differences in these factors between adolescents and their parents, using matched surveys from 182 adolescent-parent pairs in Pittsburgh and Kansas City.
  • - Findings revealed that higher conflict in adolescent acculturation led to lower ARA victimization, while increased discrimination was linked to higher rates of both victimization and perpetration; greater differences in acculturation and discrimination between adolescents and parents also correlated with higher ARA incidents.

Objective: Adolescent relationship abuse (ARA) is associated with myriad negative health outcomes. Pediatric primary care presents an opportunity to engage adolescents and parents, who can be protective against ARA, in ARA prevention; however, no family-focused, health care-based ARA interventions exist. The purpose of this study is to explore the perspectives of adolescents, parents, and health care providers (HCPs) on incorporating ARA prevention into primary care, including 1) current discussions around ARA, 2) how to best include ARA prevention education, and 3) how to address implementation barriers.

Importance: The inclusion of non-English-speaking (NES) participants in pediatric research is an essential step to improving health equity for these populations. Although some studies have shown lack of progress in NES research participation in the past decade, few have examined NES inclusivity in pediatric research or details about the practices that researchers have used to communicate with NES participants.

Objective: To assess how frequently NES families were included in pediatric research, how rates of inclusion changed over time, what languages were included, and methodological details about oral and written communication with NES participants.

Pediatricians have obligations to respond with care to all children's clinical and social vulnerabilities. Finding and addressing causes of children's stress (ie, family separation, child abuse, and trauma) are also obligations. Preventive and rescue interventions should be implemented to address potential short- and long-term harms of toxic stress and their short- and long-term consequences.

In Latin America, violence is a major public health issue causing many families to flee to the United States to seek safety. Current US immigration policies fail to address why families are forced to depart their home country or the needs of families once arriving in the United States. This article identifies root causes of family displacement, examines the insufficient protections for children in families during US immigration processing, and provides practice and policy recommendations on how to transform the US immigration system so that it is more humane for children and families forcibly displaced by violence.

Objective: To identify unmet health and social resource needs during a county-wide coronavirus disease 19 (COVID-19) stay-at-home order and phased re-opening in Western Pennsylvania.

Methods: With public health, social service, and community partners connected through an ongoing academic-community collaborative, we developed and fielded a weekly repeated cross-sectional electronic survey assessing usage of and unmet need for health and social service resources. Using 10 weeks of surveys (April 3-June 11, 2020) by Allegheny County residents, we examined variation in responses by week and by sociodemographic characteristics using chi-square tests.

Background: Latinas are at a higher risk than Caucasians for both type 1 and type 2 diabetes (DM), as well as DM-associated reproductive health (RH) complications. Healthcare providers (HCPs) should deliver culturally-sensitive care to enhance the care relationship between Latinos and HCPs and to improve patient outcomes. This study explored an expert panel's cultural understanding, experiences, barriers, and facilitators regarding RH and preconception counseling (PC) for adolescent Latinas with DM and their families.

A woman's birth experience can impact the physical and mental well-being of mothers long after the birth of their child. Little is known about the experiences of Latina women in areas with small, yet growing Latino populations. To understand Latina's perceptions of their childbirth experience and to see how insurance status impacts that experience, we conducted in-depth, semi-structured interviews with a non-proportional quota sampling of ten Latina women, five with and five without health insurance.

In a prospective study of developmental outcomes in relation to early-life otitis media, behavioral, cognitive, and language measures were administered to a large, diverse sample of children at 2, 3, 4, 6, and 9-11 years of age (N = 741). At 9-11 years of age, 9% of the children were categorized as having attention-deficit/hyperactivity disorder (ADHD) based on parent report. Compared to the non-ADHD group, the ADHD group had higher (i.

Background: The liver plays a significant role in drug metabolism; thus it would be expected that liver disease may have a detrimental effect on the activity of cytochrome P450 (CYP) enzymes. The extent to which the presence and severity of liver disease affect the activity of different individual drug-metabolizing enzymes is still not well characterized. The purpose of this study was to assess the effect of liver disease on multiple CYP enzymes by use of a validated cocktail approach.

Background And Objective: The activity of cytochrome P450 (CYP) enzymes, which determine the rate of elimination of lipid-soluble drugs, demonstrates considerable interindividual variability. The extent to which age and sex influence CYP activity remains unclear in humans. Our objectives were to determine whether in vivo activity of selected CYP enzymes is affected by age or sex and to evaluate sex bioequivalence in a large sample size.

Objectives: Determination of hepatic and intestinal cytochrome P450 (CYP) 3A activity is important, because CYP3A substrates show substantial variability in plasma concentrations as a result of variations in both hepatic and intestinal metabolism. The goals of this study were (1) to determine whether the hepatic and intestinal extraction ratios (ER(H) and ER(G), respectively) of the CYP3A probe drug midazolam are different when determined after semisimultaneous administration, as compared with administration on separate occasions (traditional method), and (2) to evaluate the hepatic and intestinal metabolism of midazolam in the presence and absence of ketoconazole by the semisimultaneous method.

Methods: Midazolam pharmacokinetics was assessed in 12 healthy volunteers after administration of midazolam, 5 mg orally, followed at 6 hours by 2 mg given by intravenous infusion.
