Waist-to-height ratio associated cardiometabolic risk phenotype in children with overweight/obesity.

BACKGROUND: Childhood overweight/obesity has been associated with an elevated risk of insulin resistance and cardiometabolic disorders. Waist-to-height ratio (WHtR) may be a simple screening tool to quickly identify children at elevated risk for cardiometabolic disorders. The primary objective of the present study was to create sex-specific tertile cut points of WHtR and assess its association with Insulin resistance and elevated liver enzyme concentrations in children, factors using cross-sectional data from the randomized, controlled Family Weight Management Study. METHODS: Baseline data from 360 children (7-12 years, mean Body Mass Index (BMI) ≥ 85th percentile for age and sex) were used to calculate WHtR tertiles by sex, male: ≤ 0.55 (T1), > 0.55- ≤ 0.59 (T2), > 0.59 (T3); female: ≤ 0.56 (T1), > 0.56- ≤ 0.6 (T2), > 0.6 (T3). The Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) was used to categorize participants as insulin-resistant (HOMA-IR ≥ 2.6) and insulin-sensitive (HOMA-IR < 2.6). Liver enzymes aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were categorized as normal vs. elevated (AST of < 36.0 µkat/L or ≥ 36.0 µkat/L; ALT of < 30.0 µkat/L or ≥ 30.0 µkat/L; ALT > 26 µkat/L males, > 22 µkat/L females). We examined differences in baseline cardiometabolic risk factors by WHtR tertiles and sex-specific multivariable logistic regression models to predict HOMA-IR and elevation of liver enzymes. RESULTS: Study participants had a mean WHtR of 0.59 ([SD: 0.06]). Irrespective of sex, children in WHtR T3 had higher BMIz scores, blood pressure, triglycerides, 2-h glucose, fasting 2-h insulin, and lower high-density lipoprotein cholesterol (HDL-C) concentrations than those in T2 and T1. After adjusting for covariates, the odds of elevated HOMA-IR (> 2.6) were over five-fold higher among males in T3 versus T1 [OR, 95%CI: 5.83, 2.34-14.52] and T2 [OR, 95%CI: 4.81, 1.94-11.92] and females in T3 [OR, 95%CI: 5.06, 2.10-12.20] versus T1. The odds of elevated ALT values (≥ 30) were 2.9 [95%CI: 1.01-8.41] fold higher among females in T3 compared to T1. CONCLUSION: In public health settings, WHtR may be a practical screening tool in pediatric populations to identify children at risk of metabolic syndrome.

Validation and reliability for the updated REAP-S dietary screener, (Rapid Eating Assessment of Participants, Short Version, v.2).

BACKGROUND: The American Heart Association (AHA) chose the REAP-S dietary screener in 2020 as one of three US dietary screeners recommended for integrating dietary assessment into clinical care. The REAP-S v.2 is an updated version that is aligned with the 2020-2025 US Dietary Guidelines and is easily incorporated into electronic medical records and taught to medical students. METHODS: The University of New England, Institutional Review Board, approved the study protocol. We evaluated the reliability and validity of the REAP-S v.2 scale by having first-year medical students (n = 167) complete both the REAP-S v.2 and a three-day food record and then analyzing their data with the following statistical techniques: Internal consistency was measured using Cronbach's alpha. Construct validity was assessed with exploratory factor analysis. Criterion validity was evaluated using analysis of variance (ANOVA) that explored the associations between REAP-S v.2 scale item responses and selected nutrient estimates from the food record analyses. The hierarchical cluster analysis classified healthy and unhealthy diet grouping under each subscale. Further using these groupings, cut points for "good" and "bad" diets for each of the three main REAP-S v.2 subscales (Food Sufficiency/Food Insufficiency; Healthy Eating Pattern and Low Nutrient Density Foods) were calculated using receiver operating characteristics (ROC) analysis. Students analyzed their three-day food intake records using an online USDA application called SuperTracker. RESULTS: The Cronbach's alpha measuring internal consistency was acceptable for the overall scale at 0.71. The exploratory factor analysis extracted three factors that roughly paralleled the three main subscales, suggesting construct validity. Most selected food record-derived nutrient values were significantly associated with scale items confirming criterion validity. The score cut points suggest that dietary counseling might be needed at ≤ 8, ≤ 10, and ≤ 16 for the above subscales. CONCLUSION: The REAP-S v.2 is intended for clinicians to use as a brief dietary screener with their patients. Tested in a population of first-year medical students, the REAP-S v.2 brief dietary screener showed acceptable internal consistency, criterion, and construct validity. It is easily scored and incorporated into the electronic medical record.

Trends in health behavior at an afterschool program: the impact of COVID-19 on students' behavior.

Background: A minority of American youth meet CDC physical activity (PA) recommendations; children in the Bronx face additional structural barriers to engaging in PA. The B'N Fit Power expansion draws on pilot programming to increase the proportion of middle school students who engage in one hour of daily PA. The COVID-19 pandemic presented additional obstacles, including increased food insecurity and suspension of organized PA programming. This research aimed to evaluate differences in baseline target behavior attainment before and after the start of the COVID-19 pandemic to inform future programming to help children reduce their risk of obesity. Methods: Afterschool program leaders at three Bronx public schools collected demographic and target behavior data at baseline and attendance data throughout the school year. Results: During the 2016-2017 and 2017-2018 school years, 76 students enrolled and completed one year of programming, which was administered at a single site (61 % Hispanic, 46% female). Of these, 76 (100%) completed a baseline target behaviors questionnaire. During the 2021-2022 school year, 417 students enrolled and completed one year of programming at one of the three sites (70% Hispanic, 48% female). 89 (21%) completed a baseline target behaviors questionnaire. Participants surveyed after the start of the COVID-19 pandemic reported drinking more sugar-sweetened beverages (Median=3 daily, IQR 2-5), sleeping less (Median=8 hours daily, IQR 6-9 hours), and consuming fast food more frequently (Median=1 time weekly, IQR 0 times weekly-2 to 3 times weekly) than those surveyed prior to the start of the pandemic. The number of PA hours completed each week trended toward significant decline (Median=3, IQR 2-5, p=0.09) in students tracked after the start of the pandemic. Conclusions: The attainment of several target behaviors among school children linked to the reduction of childhood obesity declined during the COVID-19 pandemic. These findings can be applied to enhancing existing real-world afterschool PA programming.

Prevalence and Assessment of Factors Associated with COVID-19 Vaccine Hesitancy in an Ethnic Minority Oncology Patient Population.

BACKGROUND: Complicating the COVID-19 pandemic are the healthcare disparities experienced by ethnic minorities, especially those with comorbidities including cancer. The introduction of COVID-19 vaccines has been instrumental in blunting the morbidity and mortality from the pandemic; however, vaccine hesitancy, particularly among ethnic minorities, has been a major concern. Thus, we sought to evaluate the knowledge and perspectives of COVID-19 and vaccines among our ethnic minority cancer patient population. METHODS: Following an IRB approved protocol, questionnaires were completed by patients in a predominantly ethnic minority population at a single institution between 1 February and 30 June 2021. Included were any adult cancer patients with either a solid or hematologic malignancy. RESULTS: Among the 84 patients that were offered the questionnaires, 52 patients responded, with a median age of 63.5 years. Overall, 36% were non-Hispanic Blacks and 30% were Hispanics; 65% were receiving active treatment for their cancer. Seventy-nine percent believed COVID-19 to be dangerous or harmful to them, 61% were concerned about the side effects, yet 65% considered COVID-19 vaccines as safe. Among the seven patients that refused the vaccine, (71%, n = 5) cited side effects and/or (57%, n = 4) believed that the vaccine was not needed. Overall, there was a significantly higher chance of being vaccinated if patients were receiving active cancer treatment, believed COVID-19 was harmful, or that the vaccine was safe, and knew COVID-19 was a virus. CONCLUSIONS: This exploratory study demonstrates that most ethnic minority cancer patients are receptive to vaccines, with a majority being vaccinated. However, we also discovered various reasons why this group of patients may not want be vaccinated, including concerns about side effects and perception that COVID-19 is not harmful. These findings can help us further understand the complex nature of vaccine hesitancy in ethnic minority cancer patients, and aid in developing future vaccine awareness strategies as the COVID-19 pandemic continues to evolve.

Induction Chemotherapy With FOLFIRINOX Followed by Chemoradiation With Gemcitabine in Patients With Borderline-Resectable Pancreatic Ductal Adenocarcinoma.

INTRODUCTION: Perioperative therapy is standard for patients with borderline-resectable pancreatic ductal adenocarcinoma (BR-PDAC); however, an optimal neoadjuvant regimen is lacking. We assessed the efficacy of FOLFIRINOX chemotherapy followed by gemcitabine-based chemoradiation as preoperative therapy. METHODS: Patients received 4 cycles of FOLFIRINOX, followed by 6-weekly gemcitabine with concomitant intensity-modulated radiation. The primary endpoint was the R0 resection rate. Secondary outcomes included resection rate, overall-response, overall survival (OS), progression-free survival (PFS), and tolerability. The trial was terminated early due to slow accrual. A Simon's optimal two-stage phase II trial single arm design was used. The primary hypothesis of treatment efficacy was tested using a multistage group sequential inference procedure. The secondary failure time analysis endpoints were assessed using the Kaplan-Meier procedure and the Cox regression model. RESULTS: A total of 22 patients enrolled in the study, 18 (81.8%) completed neoadjuvant treatment. The bias corrected R0 rate was 55.6% (90% CI: 33.3, 68.3; P value = .16) among patients that received at least 1 cycle of FOLFIRINOX and was 80% among patients that underwent surgery. The median OS was 35.1 months. The median PFS among patients that underwent surgery was 34 months. CONCLUSION: An R0 resection rate of 55.6% is favorable. Neoadjuvant FOLFIRINOX followed by concomitant Gemcitabine with radiation was well-tolerated. NCT01897454.

Association between violence and mental distress, self-harm and suicidal ideation and attempts among young people in Malawi.

BACKGROUND: Mental health problems ranging from depression to more severe acts such as self-harm or suicidal behaviours are a serious problem among adolescents and young adults. Exposure to violence during the life of young people can increase mental health issues for youth. This study examines the relationship between exposure to violence and mental health issues among youth using a nationally representative study in Malawi. METHODS: We analysed data from the nationally representative Violence Against Children Survey from Malawi (2013) to quantify the association between exposures to violence (physical, sexual and emotional) and their relationship with mental distress, self-harm behaviours and suicidal ideation and attempts among youth aged 13-24 years. We evaluated the association of exposures to violence against children with reported mental health conditions among women and men. We used ordinal logistic regression models with appropriate survey weights to assess exposures to violence and the three outcomes of interest. RESULTS: Children and youth aged 13-24 years exposed to violence in childhood reported higher levels of adverse mental health effects, including mental distress, self-harm behaviours and suicidal ideation and attempts. The odds of reporting these outcomes increased as the number of violence types increased. CONCLUSIONS: Understanding the risks based on different combinations of exposures to violence in Malawi can help identify populations at higher risk and optimise violence prevention strategies.

Cross-national examination of adolescent suicidal behavior: a pooled and multi-level analysis of 193,484 students from 53 LMIC countries.

INTRODUCTION: Suicide is a leading cause of adolescent mortality worldwide. We aimed to estimate the prevalence and identify individual-level and country-level factors which might explain the variability in suicidal behavior among students in 53 low to middle income countries. METHODS: We used data on adolescents aged 12-16 years from the Global School-based Student Health Surveys from 2009-2016. The suicidal behaviors investigated included suicide ideation, suicidal planning and suicide attempt. The prevalence was estimated for 53 countries, while a multilevel logistic regression analysis (33 countries) was used to investigate the associations of these behaviors with individual and country-level contextual risk factors. The contextual variables included the Gini Coefficient, Gross Domestic Product per capita, pupil-to-teacher ratios, population density, homicide rates, law criminalizing suicide and the night light index. RESULTS: The overall prevalence of suicide ideation, making a plan and suicide attempt were 10.4%, 10.3% and 11.0%, respectively. The highest prevalence rates reported were from the Americas. The strongest risk factors associated with suicidal behavior included anxiety, loneliness, no close friends and the substance abuse. Among the country level variables, the night light index was associated with making a suicide plan and attempting suicide. CONCLUSION: The non-significant country level findings were not entirely surprising given the mixed results from prior studies. Additional knowledge is thus achieved with regard to country level factors associated with suicidal behavior across adolescent populations.

Evaluation of a Mother-Infant Dyadic Video-Feedback Intervention in a Community Health Center in South Bronx, New York City.

OBJECTIVE: This study evaluates a video-feedback program's effectiveness in promoting responsive and sensitive parenting for families in care in a community health center located in the South Bronx, New York City. METHODS: Change in measures of parent responsiveness/sensitivity (Global Rating Scale), depression (Patient Health Questionnaire 9), anxiety (Generalized Anxiety Disorder 7), and parenting stress (Parenting Stress Index-Short Form) were analyzed for mother-infant dyads (N=34) completing a six-session videofeedback program between 2014 and 2016. RESULTS: Participants were primarily mothers of color (30% African American; 63% Hispanic) with young infants (mean age 8 months). At program completion, mothers demonstrated a significant improvement of 19% in maternal responsiveness and fewer depressive and anxious symptoms. CONCLUSION: Cost-effectiveness studies are needed to compare parenting interventions by setting (community health center, home, or mental health facility) for acceptability and effectiveness to determine best practice models for communities challenged by poverty, trauma, and health disparities.

Anti-HPV16 Antibody Titers Prior to an Incident Cervical HPV16/31 Infection.

The goal of this study was to investigate the serological titers of circulating antibodies against human papillomavirus (HPV) type 16 (anti-HPV16) prior to the detection of an incident HPV16 or HPV31 infection amongst vaccinated participants. Patients were selected from a prospective post-HPV vaccine longitudinal cohort at Mount Sinai Adolescent Health Center in Manhattan, NY. We performed a nested case-control study of 43 cases with incident detection of cervical HPV16 (n = 26) or HPV31 (n = 17) DNA who had completed the full set of immunizations of the quadrivalent HPV vaccine (4vHPV). Two control individuals whom had received three doses of the vaccine (HPV16/31-negative) were selected per case, matched on age at the first dose of vaccination and follow-up time in the study: a random control, and a high-risk control that was in the upper quartile of a sexual risk behavior score. We conducted an enzyme-linked immunosorbent assay (ELISA) for the detection of immunoglobulin G (IgG) antibodies specific to anti-HPV16 virus-like particles (VLPs). The results suggest that the average log antibody titers were higher among high-risk controls than the HPV16/31 incident cases and the randomly selected controls. We show a prospective association between anti-HPV16 VLP titers and the acquisition of an HPV16/31 incident infection post-receiving three doses of 4vHPV vaccine.

Incidence and Types of Human Papillomavirus Infections in Adolescent Girls and Young Women Immunized With the Human Papillomavirus Vaccine.

Importance: Rates of human papillomavirus (HPV) infection have decreased since the introduction of HPV vaccines in populations with high vaccine uptake. Data are limited for adolescent and young adult populations in US metropolitan centers. Objective: To determine HPV infection rates in adolescent girls and young women aged 13 to 21 years in New York City following HPV vaccination. Design, Setting, and Participants: This cohort study of type-specific cervical HPV detection was conducted at a large adolescent-specific integrated health center in New York City between October 2007 and September 2019. Participants included an open cohort of adolescent girls and young adult women who received the HPV vaccine (Gardasil; Merck & Co) over a 12-year period following HPV vaccination introduction. Data analysis was concluded September 2019. Exposures: Calendar date and time since receipt of first vaccine dose. Main Outcomes and Measures: Temporal associations in age-adjusted postvaccine HPV rates. Results: A total of 1453 participants, with a mean (SD) age at baseline of 18.2 (1.4) years, were included in the cohort (African American with no Hispanic ethnicity, 515 [35.4%] participants; African American with Hispanic ethnicity, 218 [15.0%] participants; Hispanic with no reported race, 637 [43.8%] participants). Approximately half (694 [47.8%] participants) were vaccinated prior to coitarche. Age-adjusted detection rates for quadrivalent vaccine types (HPV-6, HPV-11, HPV-16, and HPV-18) and related types (HPV-31, and HPV-45) decreased year over year, with the largest effect sizes observed among individuals who had been vaccinated before coitarche (adjusted odds ratio [aOR], 0.81; 95% CI, 0.67-0.98). By contrast, detection was higher year over year for nonvaccine high-risk cervical HPV types (aOR, 1.08; 95% CI, 1.04-1.13) and anal HPV types (aOR, 1.11; 95% CI, 1.05-1.17). The largest effect sizes were observed with nonvaccine types HPV-56 and HPV-68. Conclusions and Relevance: Whereas lower detection rates of vaccine-related HPV types were observed since introduction of vaccines in female youth in New York City, rates of some nonvaccine high-risk HPV types were higher. Continued monitoring of high-risk HPV prevalence is warranted.

Neighborhood Profiles and Body Mass Index Trajectory in Female Adolescents and Young Adults.

PURPOSE: The purpose of this study is to identify distinct neighborhood profiles patterned by key structural, physical, and social characteristics and test whether living in different profiles are associated with body mass index trajectories during adolescence in racial/ethnic minority female youth. METHODS: Participants were 1,328 sexually active female adolescents and young adults aged 14-23 years, predominately Hispanic and black, enrolled in an human papillomavirus type 4 vaccine (Gardasil) surveillance study at a large adolescent health clinic in New York City between 2007 and 2018. Body mass index was calculated from weight and height every 6 months. A comprehensive set of neighborhood structural, social, and physical characteristics from multiple national and state datasets was linked to each participant based on home address. RESULTS: Latent profile analysis revealed five distinct neighborhood profiles in New York City: High Structural/High Social Advantage, Moderate Advantage/Low Crime, Low SES (Socioeconomic Status)/High Activity, Low SES/High Social Advantage, and High Disadvantage. Results from multilevel growth curve analysis revealed that living in Low SES/High Activity neighborhoods was associated with a lower BMI at age 22 (b = -1.32, 95% confidence interval -2.49, -.16), as well as a slower increase in BMI from age 14 to 22 years (b = -.22, 95% confidence interval -.46, .02), compared to the High Disadvantage profile. CONCLUSIONS: Our findings suggest that improving neighborhood structural, social, and physical environments may help promote healthy weight and reduce health disparities during adolescence and young adulthood.

Cardiopulmonary resuscitation skill training and retention in teens (CPR START): A randomized control trial in high school students.

AIM: High school students are currently the largest group of individuals in the US receiving CPR training every year. This study examines the effect of adding a real-time visual feedback device to a standard instructor-led CPR course on skill acquisition and retention in high school students. METHODS: All study participants underwent baseline CPR skill testing and received a standard instructor-led compression-only CPR course. We then randomized students to a 'Feedback Group', consisting of 2 min of CPR training using a real-time visual feedback device, or 'Standard Group' that continued to practice on the inflatable manikin. CPR skills for all students were tested afterwards using the feedback device and reported as a compression score (CS) derived from their chest compression depth, rate, hand position, and full chest recoil. We compared the CS at baseline, week-0 (immediately post-intervention), week-10, week-28, and week-52 between groups. RESULTS: A total of 220 students were included in the analyses (Feedback Group = 110, Standard Group = 110). Both groups showed similar CPR performance at baseline. At week-0, the Feedback Group had a significantly higher CS compared to the Standard Group (adjusted difference: 20% [95% CI: 11%-29%; p < 0.001]). This difference attenuated over time but remained significant at the week-10 and week-28 follow-up; however, by the week-52 follow-up, there was no significant difference between groups. CONCLUSIONS: Using a real-time visual feedback device during CPR training significantly improves skill acquisition and retention in high school students and should be integrated into the high school CPR curriculum.

Changes in cannabis, tobacco, and alcohol use among sexually active female adolescents and young adults over a twelve-year period ending in 2019.

BACKGROUND: The United States has experienced an increasing divergence in cannabis, tobacco, and alcohol use among adolescents and young adults (AYA). We assessed the changes in cannabis, tobacco and alcohol use in an inner-city population of predominantly minority AYA females attending a large adolescent-specific health center in New York City. METHODS: This was a longitudinal study of AYA women recruited and followed over a twelve-year period between 2007 and 2019. Lifetime and past 30-day use were assessed by self-administered questionnaire every six months. In addition, we assessed associations with race, ethnicity, sexual behaviors, receipt of social services, living situation at home (e.g., with or without parents), and use of other drugs. RESULTS: Participants included 1549 AYA females aged 13-21 at baseline, 95% of whom were youth of color. Use of cannabis increased significantly over the twelve-year period, with frequent cannabis use (≥20 times in 30-days) increasing almost 18% per year (OR = 1.18; 95%CI:1.13-1.23). In contrast, past 30-day tobacco use declined over the same period (OR = 0.86; 95%CI:0.83-0.89). Past 30-day cannabis use was more likely among African Americans (OR = 1.33; 95%CI:1.08-1.63), women who had sex with both men and women compared to with men only (OR = 1.44; 95%CI:1.18-1.75), recent users of tobacco (OR = 2.20; 95%CI:1.92-2.52) and alcohol (OR = 2.84; 95%CI:2.52-3.20), and ever users of other drugs (OR = 1.69; 95%CI:1.44-1.99), independent of age, time and living situation. CONCLUSIONS: Increasing rates of cannabis use and the association with concurrent tobacco and alcohol use in AYA females underscore the need to screen for unhealthy cannabis use, in addition to tobacco and alcohol, especially among inner-city AYA.

Trends in health behavior and weight outcomes following enhanced afterschool programming participation.

BACKGROUND: The United States needs to increase access to effective obesity prevention and treatment programming for impoverished youth at risk for health disparities. Although recommended, schools have difficulty consistently implement evidence-based obesity programing. We report on the effectiveness of adding structured nutrition education and minimum physical activity (PA) requirements to standard middle school after-school programming. METHODS: Using a longitudinal pre-post study design, we evaluated program effectiveness at one year on target behaviors on students recruited during three consecutive school years (2016-2018). We used generalized linear (or logistic) mixed-effects modeling to determine: 1) impact on healthy weight and target healthy behavior attainment, and 2) whether target behavior improvement and weight change were associated with after-school program attendance. The seven target behaviors relate to eating healthy, physical activity, and sleep. RESULTS: Over the three years, a total of 76 students enrolled and completed one year of programming (62% Hispanic, 46% girls, 72% with BMI > 85th %ile, 49% with BMI > 95th %ile). Of students with BMI > 85th %ile, 44% maintained or decreased BMI Z-score. There were improvements (non-significant) in BMI Z-score and the adoption of four healthy eating behaviors: fruit, vegetables, sugar-free beverages, and unhealthy snack food. Students with higher after-school attendance (> 75%) had greater improvements (non-significant) in composite behavior scores, BMI Z-score, and in most target behaviors (5/7) than students with lower after-school attendance (< 75%). Sleep improvements were significantly associated with BMI Z-score decrease (Beta = - 0.05, 95% CI (- 0.1,-0.003), p = 0.038.) CONCLUSIONS: Enhancement of existing after-school programming with structured nutrition education and minimum physical activity requirements demonstrates positive improvements in several health behaviors and weight outcomes. Adopting enhanced after-school programming increases access to health activities and may bring us closer to solving obesity in at-risk youth in impoverished communities.

Perspectives of parents of working adolescents in Ontario, Canada.

BACKGROUND: More than half of adolescents have jobs in summer or sometime during the year. While employers are ultimately responsible for their safety, parents are often important in helping their children navigate the work environment. Our study examines the attitudes, beliefs and types of involvement parents have in their children's work. METHODS: We modeled a telephone survey of 507 English-speaking parents of working adolescents in Ontario, Canada on a US study and examined their perspectives, comparing to earlier findings from the U.S. parents. RESULTS: Most Ontario parents helped their teens consider questions to ask about work, for example, work hours (90.7%) and job tasks (78.2%) and fewer about workplace safety (57.9%). Parents overall were concerned about their teens, especially younger teens, getting behind on schoolwork (69.3%), being rushed on the job (60.1%) and doing hazardous tasks (58.3%) or working alone (51.9%), or being at work during a robbery (74.5%). Parents of 14-17-year-old daughters were more concerned about their child being assaulted than were parents of sons (62.4% vs. 51.4%), particularly if the teen was in the 18-19 age group (74.3% vs. 52.5%). Half the parents indicated 10-19 h per week was the right amount of work time for their teen, and most agreed that laws should limit the number of hours of youth work. CONCLUSIONS: Overall, Ontario parents appear to be more concerned about the safety and also more involved in the work of their adolescent children than U.S. parents previously surveyed. Parents are engaged with their children about their work and may serve as valuable assets to helping to advocate for safe work policies and environments.

Profiles of Childhood Maltreatment: Associations with Sexual Risk Behavior during Adolescence in a Sample of Racial/Ethnic Minority Girls.

This study examines associations between childhood maltreatment and developmental trajectories of sexual risk behaviors (SRBs) in a sample of 882 sexually active adolescent girls, predominantly Hispanic or Black, assessed every 6 months between 13 and 23 years. Latent profile analyses revealed four distinct maltreatment profiles: Low Maltreatment (76%), Moderate Emotional Neglect Only (15%), Severe Physical/Emotional Abuse (3%), and Severe Sexual Abuse (6%). Multilevel growth analyses showed the Moderate Emotional Neglect Only and Severe Sexual Abuse profiles exhibited more SRBs starting in late adolescence, and the Severe Sexual Abuse profile also exhibited a faster increase than the Low Maltreatment profile. Understanding heterogeneity within maltreated populations may have important implications for healthy sexual development.

Predictors of prostate bed recurrence on magnetic resonance imaging in patients with rising prostate-specific antigen after radical prostatectomy.

INTRODUCTION: Radical prostatectomy (RP) is a standard treatment modality for localized prostate cancer. Biochemical failure after RP is usually evaluated with whole-body imaging to exclude distant metastatic disease, and pelvic magnetic resonance imaging (MRI) to detect local recurrence in the prostatectomy bed. The goal of this study is to correlate disease characteristics and demographic data in patients with rising prostate-specific antigen (PSA) after RP to determine association with MRI-detected cancer recurrence. METHODS: Sixty-four patients who underwent pelvic MRI for rising PSA after RP and had complete clinical and pathological data available were included. Using Chi-squared testing, we analyzed PSA levels, pathological disease characteristics (prostate cancer risk group, Gleason score, extracapsular extension, positive surgical margin, seminal vesicle involvement, perineural invasion, lymphovascular invasion, and PSA level before MRI), time from surgery to biochemical failure, and patient demographic characteristics as potential predictors of MRI-detected local recurrence. RESULTS: Definite MRI-detected local recurrence was observed in 17/64 patients (27%). Eleven (17%) patients had a suspicious lesion with the differential of scarring, retained seminal vesicle, or recurrent cancer. Thirty-six (56%) patients had no evidence of tumor in the prostate bed or pelvis on MRI. Patient race was associated with likelihood of detecting a prostate nodule on MRI (p=0.04), with African American patients having 82% lower odds of MRI-detected tumor recurrence compared with white patients (p=0.045). No other tumor or patient characteristic was significantly associated with MRI-detected recurrence. CONCLUSIONS: African American patients with biochemical failure after RP are less likely to have MRI-detectable recurrence in the prostate bed compared with white patients.

Association of Addition of Ablative Therapy Following Transarterial Chemoembolization With Survival Rates in Patients With Hepatocellular Carcinoma.

Importance: Hepatocellular carcinoma (HCC) is a heterogeneous disease with many available treatment modalities. Transarterial chemoembolization (TACE) is a valuable treatment modality for HCC lesions. This article seeks to evaluate the utility of additional ablative therapy in the management of patients with HCC who received an initial TACE procedure. Objective: To compare the overall survival (OS) and freedom from local progression (FFLP) outcomes after TACE alone with TACE that is followed by an ablative treatment regimen using stereotactic body radiation therapy, radiofrequency ablation, or microwave ablation for patients with HCC. Design, Setting, and Participants: This cohort study of 289 adults at a single urban medical center examined survival outcomes for patients with nonmetastatic, unresectable HCC who received ablative therapies following TACE or TACE alone from January 2010 through December 2018. The Lee, Wei, Amato common baseline hazard model was applied for within-patient correlation with robust variance and Cox regression analysis was used to assess the association between treatment group (TACE vs TACE and ablative therapy) and failure time events (FFLP per individual lesion and OS per patient), respectively. In both analyses, the treatment indication was modeled as a time-varying covariate. Landmark analysis was used as a further sensitivity test for bias by treatment indication. Exposures: TACE alone vs TACE followed by ablative therapy. Main Outcomes and Measures: Freedom from local progression and overall survival. Hypotheses were generated before data collection. Results: Of the 289 patients identified, 176 (60.9%) received TACE only and 113 (39.1%) received TACE plus ablative therapy. Ablative therapy included 45 patients receiving stereotactic body radiation therapy, 39 receiving microwave ablation, 20 receiving radiofrequency ablation, and 9 receiving a combination of these following TACE. With a median (interquartile range) follow-up of 17.4 (9.5-29.5) months, 242 of 512 (47.3%) lesions progressed, 211 in the group with TACE alone and 31 in the group with TACE plus ablative therapy (P < .001). Over 3 years, FFLP was 28.1% for TACE alone vs 67.4% for TACE with ablative therapy (P < .001). The 1-year and 3-year OS was 87.5% and 47.1% for patients with lesions treated with TACE alone vs 98.7% and 85.3% for patients where any lesion received TACE plus ablative therapy, respectively (P = .01), and this benefit remained robust on landmark analyses at 6 and 12 months. The addition of ablative therapy was independently associated with OS on multivariable analysis for all patients (hazard ratio, 0.26; 95% CI, 0.13-0.49; P < .001) and for patients with Barcelona clinic liver cancer stage B or C disease (hazard ratio, 0.31; 95% CI, 0.14-0.69; P = .004). Conclusions and Relevance: Adding ablative therapy following TACE improved FFLP and OS among patients with hepatocellular carcinoma. This study aims to guide the treatment paradigm for HCC patients until results from randomized clinical trials become available.

The interaction between pubertal timing and childhood maltreatment on the risk of human papillomavirus infection among adolescent girls and young women.

PURPOSE: The goal of this study was to evaluate the effect of pubertal timing, and its interaction with prior childhood maltreatment, on the risk of cervical human papillomavirus (HPV) among sexually active adolescent minority female adolescents and young adults. METHODS: This cross-sectional study includes 842 adolescent girls and young women (aged 12 to 20 years; predominately Black and Hispanic) enrolled in an HPV vaccine surveillance study at a large adolescent health clinic in New York City between 2007 and 2016. Pubertal timing was assessed by self-reported age at menarche at baseline, with "early" and "late" defined as one standard deviation below (<11 years) or above (>13 years) the mean. Childhood exposure to abuse (sexual, physical and emotional) and neglect (physical and emotional) was assessed using the Childhood Trauma Questionnaire. Over 40 types of HPV infection were detected using the polymerase chain reaction in cervical Pap specimens. RESULTS: Results from multivariable logistic regression showed that early and late pubertal timing were marginally associated with a higher risk of HPV infection, adjusting for demographic and health covariates. Childhood maltreatment moderated the association between early pubertal timing and HPV infection: early pubertal timing was associated with a higher risk for HPV infection among maltreated girls (OR = 3.32, 95%CI:1.61-6.85), but not among non-maltreated girls (OR = 0.96, 95%CI:0.61-1.50; p-interaction<0.01). CONCLUSIONS: Variation in the timing of puberty and history of childhood maltreatment may have implications for adolescent sexual and reproductive health. Findings suggest that clinicians need to assess the biological and psychosocial risks in caring for youth.
