BACKGROUND:While previous research has documented the impact of violence on substance use, none has looked longitudinally across the lifespan to measure independent effects of direct and indirect violence exposure. OBJECTIVE:To examine independent associations between adolescent experiences of violence and subsequent substance use in adolescence and adulthood in the United States. METHOD/METHODS:Using the National Longitudinal Study of Adolescent to Adult Health (N = 12,288), we examined being shot or stabbed ("experienced"), being threatened with a knife or gun ("threatened"), and seeing someone either shot or stabbed ("witnessed") during adolescence (Wave I) as correlates of substance use in adolescence and adulthood (Wave IV) via logistic regression. RESULTS:Violence exposure was a significant correlate of drug use in adolescence and several associations remained significant in adulthood. Witnessing violence had the highest point estimates in the adjusted models in adolescence for each substance use outcome (e.g., Cocaine-Adjusted Odds Ratios [AOR] = 2.59, 95% confidence interval [CI] = 1.21, 5.54). However, the point estimates for threatened with violence or experienced violence were highest in three out of the four drug outcomes in adulthood (e.g., Threatened with violence: Binge drinking-AOR = 1.41, 95% CI = 1.08, 1.83). Conclusion/Importance: Adolescent exposure to witnessing violence had stronger effects on substance use in adolescence, while experiencing and being threatened with violence in adolescence had stronger effects on substance use in adulthood. Violence prevention efforts targeted toward adolescents may lead to a reduction in substance use throughout the life-course, and clinicians and policy makers should be aware of the downstream effects of violence experienced in adolescence.

Purpose: To compare the effectiveness of standard treatment using partial nephrectomy and personalized management strategies for small renal tumors using a simulation model.
Material(s) and Method(s): A decision-analytic model was constructed to compare life expectancy of management strategies for small renal tumors using: (1) uniform treatment with partial nephrectomy; or personalized options incorporating (2) percutaneous ablation; (3) biopsy, with triage of renal cell carcinoma (RCC) to nephron-sparing therapy; (4) watchful waiting for growth; and (5) MRI-based selection of papillary RCC for watchful waiting. The model included patient age, gender, chronic kidney disease (CKD) stage, renal functional decline specific to treatment type, comorbidities, benign and malignant tumors, RCC subtypes, and differential risks of cancer progression. Decisionmaking based on histologic subtype from biopsy was tested in sensitivity analysis.
Result(s): Partial nephrectomy was favored in patients of all ages with normal renal function. Otherwise, personalized strategies improved life expectancy compared with partial nephrectomy. The favorability of personalized therapy depended upon CKD stage, tumor anatomy and comorbidities. For example, patients with CKD stages 2 or 3a and moderate or high tumor anatomic complexity were most effectively treated with MRI-based management when they had no comorbidities (+ 2.57 years for MRI vs. partial nephrectomy in CKD 3a, Nephrometry Score 10), but with Charlson Comorbidity Index >=1, biopsy or watchful waiting for growth were most effective. Biopsy-based management became most effective in multiple patient subcategories when histologic subtype guided treatment selection.
Conclusion(s): Personalized treatment selection for small renal tumors likely improves life expectancy for patients with abnormal renal function

Purpose It is clinically challenging to integrate genomic-classifier results that report a numeric risk of recurrence into treatment recommendations for localized prostate cancer, which are founded in the framework of risk groups. We aimed to develop a novel clinical-genomic risk grouping system that can readily be incorporated into treatment guidelines for localized prostate cancer. Materials and Methods Two multicenter cohorts (n = 991) were used for training and validation of the clinical-genomic risk groups, and two additional cohorts (n = 5,937) were used for reclassification analyses. Competing risks analysis was used to estimate the risk of distant metastasis. Time-dependent c-indices were constructed to compare clinicopathologic risk models with the clinical-genomic risk groups. Results With a median follow-up of 8 years for patients in the training cohort, 10-year distant metastasis rates for National Comprehensive Cancer Network (NCCN) low, favorable-intermediate, unfavorable-intermediate, and high-risk were 7.3%, 9.2%, 38.0%, and 39.5%, respectively. In contrast, the three-tier clinical-genomic risk groups had 10-year distant metastasis rates of 3.5%, 29.4%, and 54.6%, for low-, intermediate-, and high-risk, respectively, which were consistent in the validation cohort (0%, 25.9%, and 55.2%, respectively). C-indices for the clinical-genomic risk grouping system (0.84; 95% CI, 0.61 to 0.93) were improved over NCCN (0.73; 95% CI, 0.60 to 0.86) and Cancer of the Prostate Risk Assessment (0.74; 95% CI, 0.65 to 0.84), and 30% of patients using NCCN low/intermediate/high would be reclassified by the new three-tier system and 67% of patients would be reclassified from NCCN six-tier (very-low- to very-high-risk) by the new six-tier system. Conclusion A commercially available genomic classifier in combination with standard clinicopathologic variables can generate a simple-to-use clinical-genomic risk grouping that more accurately identifies patients at low, intermediate, and high risk for metastasis and can be easily incorporated into current guidelines to better risk-stratify patients.

The gap in school readiness skills between children growing up in poverty and other children has become a major policy issue as increasing proportions of families are living in poverty, especially in low-wealth rural communities. The purpose of this paper was to document the degree to which depth, persistence, and timing of poverty was related to the early development of children in a representative sample of 1,292 families in two of the four poor rural regions in the United States, labeled Appalachia and the Black South. Analyses documented the emergence of the poverty gap in the child's first 5 years of life, asking when the gap emerged and whether it continued to grow through the early childhood period. Findings indicated that families who experienced poverty during the child's first 2-years showed substantially lower cognitive, language, executive functioning, and social skills by 2 to 3 years of age (0.5 to 1.0 SD difference) and these gaps appeared to stabilize between 3 and 5 years of age. Transitions into deep poverty during the preschool period (3- to 5-years) were also related to substantially lower scores, and to a lesser extent, transitions out of poverty were related to higher skill levels. Accounting for baseline demographic and maternal characteristics diminished the poverty gap, but did not eliminate it. The poverty gaps at 3-years in language, executive functioning, and social skills accounted for much of the poverty gaps observed at 5-years. Policy implications for early care and education programming are discussed.

BACKGROUND:Adverse childhood experiences (ACEs) is a significant public health and social welfare problem in low-and middle income countries (LMICs). However, most ACEs research is based on developed countries, and little is known about mechanisms of early ACEs on adulthood health and offspring's wellbeing for populations in LMICs. This area is needed to guide social welfare policy and intervention service planning. This study addresses these research gaps by examining patterns of ACEs and understanding the role of ACEs on adulthood health (i.e., physical, mental health, experience of underage pregnancy) and offspring's mental health in Kenya. The study was guided by an Integrated Family Stress and Adverse Childhood Experiences Mediation Framework. METHODS:Three hundred ninety four mothers from two informal communities in Kariobangi and Kangemi in Nairobi were included in this study. The Adverse Childhood Experiences International Questionnaire (ACE-IQ), the Kessler Psychological Distress Scale (K10), Overall Health and Quality of Life items, and Child Behavior Checklist were used to study research questions. Data was gathered through a one-time interview with mothers. Structural Equational Modeling (SEM) was applied for mediational mechanism testing. RESULTS:Among 13 ACE areas, most mothers experienced multiple adversity during their childhood (Mean (SD) = 4.93 (2.52)), with household member treated violently (75%) as the most common ACE. SEM results showedthat all domains of ACEs were associated with some aspects of maternal health, and all three domains of maternal health (maternal mental health, physical health, and adolescent pregnancy) were significantly associated with development of offspring's mental health problems. CONCLUSION/CONCLUSIONS:ACEs are highly prevalent in Kenyan informal settlements. Consistent with cross cultural literature on family stress model, maternal ACEs are robust predictors for poor child mental health. Preventive interventions for child mental health need to address maternal adverse childhood traumatic experiences as well as their current health in order to effectively promote child mental health.

OBJECTIVE:To determine whether medical errors, family experience, and communication processes improved after implementation of an intervention to standardize the structure of healthcare provider-family communication on family centered rounds. DESIGN/METHODS:Prospective, multicenter before and after intervention study. SETTING/METHODS:Pediatric inpatient units in seven North American hospitals, 17 December 2014 to 3 January 2017. PARTICIPANTS/METHODS:All patients admitted to study units (3106 admissions, 13171 patient days); 2148 parents or caregivers, 435 nurses, 203 medical students, and 586 residents. INTERVENTION/METHODS:Families, nurses, and physicians coproduced an intervention to standardize healthcare provider-family communication on ward rounds ("family centered rounds"), which included structured, high reliability communication on bedside rounds emphasizing health literacy, family engagement, and bidirectional communication; structured, written real-time summaries of rounds; a formal training programme for healthcare providers; and strategies to support teamwork, implementation, and process improvement. MAIN OUTCOME MEASURES/METHODS:Medical errors (primary outcome), including harmful errors (preventable adverse events) and non-harmful errors, modeled using Poisson regression and generalized estimating equations clustered by site; family experience; and communication processes (eg, family engagement on rounds). Errors were measured via an established systematic surveillance methodology including family safety reporting. RESULTS:26.5% (12.7% to 7.3%), P=0.02) increased. Trainee teaching and the duration of rounds did not change significantly. CONCLUSIONS:Although overall errors were unchanged, harmful medical errors decreased and family experience and communication processes improved after implementation of a structured communication intervention for family centered rounds coproduced by families, nurses, and physicians. Family centered care processes may improve safety and quality of care without negatively impacting teaching or duration of rounds. TRIAL REGISTRATION/BACKGROUND:ClinicalTrials.gov NCT02320175.

Transgender and gender-nonconforming (TGNC) youth who suffer from gender dysphoria are at a substantially elevated risk of numerous adverse physical and psychosocial outcomes compared with their cisgender peers. Innovative treatment options used to support and affirm an individual's preferred gender identity can help resolve gender dysphoria and avoid many negative sequelae of nontreatment. Yet, despite advances in these relatively novel treatment options, which appear to be highly effective in addressing gender dysphoria and mitigating associated adverse outcomes, ethical challenges abound in ensuring that young patients receive appropriate, safe, affordable treatment and that access to this treatment is fair and equitable. Ethical considerations in gender-affirming care for TGNC youth span concerns about meeting the obligations to maximize treatment benefit to patients (beneficence), minimizing harm (nonmaleficence), supporting autonomy for pediatric patients during a time of rapid development, and addressing justice, including equitable access to care for TGNC youth. Moreover, although available data describing the use of gender-affirming treatment options are encouraging, and the risks of not treating TGNC youth with gender dysphoria are evident, little is known about the long-term effects of both hormonal and surgical interventions in this population. To support ethical decision-making about treatment options, we encourage the development of a comprehensive registry in the United States to track long-term patient outcomes. In the meantime, providers who work with TGNC youth and their families should endeavor to offer ethically sound, patient-centered, gender-affirming care based on the best currently available evidence.
