ABSTRACT
INTRODUCTION: Approximately 1 in 7 pregnant women in the USA report past-month alcohol use. Strong evidence connects prenatal alcohol exposure with a range of adverse perinatal outcomes, including the spectrum of conditions known as fetal alcohol spectrum disorders. Screening and Brief Intervention (SBI) has been recommended for pregnant women but has proven difficult to implement. This study will test the efficacy of single-session technology-delivered SBI (electronic SBI) for alcohol use in pregnancy, while simultaneously evaluating the possible additional benefit of tailored text messages and/or booster sessions in a 3×2 factorial trial. METHOD AND ANALYSIS: This full factorial trial will use online advertising and clinic-based flyers to recruit pregnant women meeting criteria for unhealthy alcohol use, and randomly assign them to one of six conditions crossing three levels of brief intervention (none, single 120-minute session and single session plus two 5-minute boosters) with two levels of tailored text messaging (none vs twice weekly messages). The primary analysis will test for dose-response effects of the brief intervention on alcohol abstinence, defined as no self-report of alcohol use in the 90 days prior to 34 weeks' gestation, and negative results for ethyl glucuronide analysis of fingernail samples. Secondary analyses will examine main and interaction effects of tailored text messaging as well as intervention effects on birth outcomes. ETHICS AND DISSEMINATION: Ethical approval was provided by the Michigan State University Biomedical and Health Institutional Review Board (STUDY00005298). Results will be presented at conferences and community forums, in addition to being published in a peer-reviewed journal. Intervention content demonstrating sufficient efficacy and safety will be made publicly available. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT04332172).

Cutaneous leishmaniasis is a parasitic infection that causes significant maternal morbidity, and even fetal mortality, during pregnancy, yet there are limited therapeutic options. Here, we report a case of leishmaniasis in a pregnant immigrant with exuberant mucocutaneous lesions with favorable response to liposomal amphotericin B.
ABSTRACT
BACKGROUND: Sclerosing stromal tumors (SSTs) are rare benign ovarian tumors that occur in adolescents and young adults. They are often treated with unilateral salpingo-oopherectomy due to concern for malignancy. CASE: A 13-year-old postpubertal female presented with sharp, constant abdominal pain with physical exam concerning for a lower abdominal mass. An ultrasound revealed a 9.7-cm solid, heterogenous left ovarian mass. The abdomen and pelvis CT confirmed the findings and showed a predominantly cystic mass arising from the left adnexa. During surgery, a smooth and distinct mass arising from the left ovary was encountered without abnormal findings in surrounding structures. A cystectomy was performed, and intraoperative findings showed no evidence of malignancy. Based on the lab, imaging, and surgical findings, staging and salpingo-oopherectomy were not pursued. SUMMARY AND CONCLUSION: Given the benign nature of SSTs, it is important to entertain the diagnosis in adolescents presenting with clinically congruent ovarian masses. The minimally invasive approach allows for sparing of the ovary in the adolescent population.

Various professional organizations have weighed in on the practice utility of speculum examinations. The US Preventive Services Task Force (USPSTF), American Academy of Pediatrics (AAP), and American College of Physicians (ACP) have recommended against internal pelvic examinations in asymptomatic patients, whereas the American College of Obstetricians and Gynecologists (ACOG) has encouraged shared decision making. Although a pelvic examination can be a stressful event for adolescents, studies have shown that early discussions and performing the examination in a trusting environment can mitigate the worries and improve the patient-provider relationship. In this commentary, we discuss the literature and conclude that performing a pelvic examination in the asymptomatic adolescent and young adult patient is ultimately a matter of shared decision making. The benefits of conducting the examination in a nonthreatening environment, minimizing "exceptionalization" of the female genitalia, and strengthening the patient-provider relationship should be highlighted during the discussions.

OBJECTIVE: Healthcare hackathons are fast-paced, mentored events that bring together individuals with diverse skillsets to identify clinical needs and propose solutions. Traditionally geared toward device development and workflow optimization, platforms that address women and minorities in surgery are rare. We aimed to expand the traditional healthcare hackathon model to include a novel workforce development (WD) track to address concerns faced by surgeons and trainees. DESIGN: The WD track was created as part of the first surgical hackathon at our academic institution. In a single-day event, participants identified concerns (pain points) of diversity and sustainability in surgery, formed interdisciplinary teams, and pitched solutions. Pain points, project themes, and postevent survey results were analyzed and compared between WD and other tracks. SETTING: Participants were surveyed at Yale School of Medicine, an academic medical tertiary center, in September 2018. PARTICIPANTS: Thirty-one total participants. Twenty-five (80.6%) responded to the survey. RESULTS: Of 57 problem pitches, 23 (40.4%) were related to WD. Issues highlighted 5 themes: training and career exploration, leadership and communication of skills, mental health and burnout prevention, surgeon discrimination and harassment, and work-life balance. Participants formed 6 groups, with 1 focused on WD. There was no difference between participants in the WD track and non-WD track counterparts with regard to excitement for continuing their project beyond the hackathon (4.00, standard deviation [SD] 0.89, vs. 3.63, SD 1.12, pâ¯=â¯0.43), and in their perception of the mentorship they received (4.00, SD 1.00, vs. 4.11, SD 0.78, pâ¯=â¯0.84). The project presented within the WD track, on culturally sensitive scrub wear, was 1 of 3 prize-winners. CONCLUSIONS: The first WD track at a healthcare hackathon identified 5 themes of unmet workforce needs. The pilot demonstrated that WD tracks can be implemented in hackathons with similar results to traditional tracks and create innovative and sustainable solutions to surgical workforce concerns.

Medical students in the United States are engaging less with formal classroom curricula. This shift in decreased attendance and participation is largely driven by an incentive structure in medical education focused on standardized test scores, research and letters of recommendation. In this essay, the authors describe the student experience of a preclinical lecture, struggling to balance learning about a patient with Alcohol Use Disorder with the demands of extracurricular expectations.

Background: Little is known about the role of perceived neighborhood environment as a determinant of physical activity (PA) and sedentary time (ST) in understanding obesity-related health behaviors. We focus on a biracial, socioeconomically diverse population using objectively measured ST, which is under-represented in the literature. Methods: We examined the association between self-reported neighborhood perception (Likert-scale questions), PA using the Baecke questionnaire, and both non-sedentary time and ST using accelerometry from wave 4 of the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study (n = 2,167). After applying exclusion criteria, the sample size was n = 1,359 for analyses of self-reported PA and n = 404 for analyses of accelerometry data. Factor analysis identified key neighborhood characteristics to develop a total neighborhood perception score (NPS). Higher NPS indicated less favorable neighborhood perception. Linear regression was used to determine the relationship between NPS, PA, non-sedentary time, and ST. Results: Complete data were available for n = 1,359 [age 56.6(9.0) years, 59.5% female, 62.2% African American] for whom we identified four neighborhood perception factors: (1) concern about crime, (2) physical environment, (3) location of violent crime, and (4) social environment. Worsening perception of the overall neighborhood [ß = -0.13 (SE = 0.03); p = 0.001], the physical environment [-0.11 (0.05); p = 0.03], and the social environment [-0.46 (0.07); p < 0.0001] were associated with decreased PA. Worsening perception of the overall neighborhood [1.14 (0.49); p = 0.02] and neighborhood social environment [3.59 (1.18); p = 0.003] were associated with increased ST over the day. There were no interactions for race, sex, poverty status, or economic index. Conclusion: Poor overall neighborhood perception, perceived social environment, and perceived neighborhood physical environment are associated with PA and ST in a multi-racial, socioeconomically diverse cohort of urban adults. Clinical Trial Registration: The HANDLS study is registered at ClinicalTrials.gov as NCT01323322.
ABSTRACT
PURPOSE: Decreased cardiorespiratory fitness (CRF) is associated with an increased risk of cardiovascular disease. However, little is known how the interaction of diet, physical activity (PA), and sedentary time (ST) affects CRF among adolescents. By using a nationally representative sample of U.S. adolescents, we used cluster analysis to investigate the interactions of these behaviors with CRF. We hypothesized that distinct clustering patterns exist and that less healthy clusters are associated with lower CRF. METHODS: We used 2003-2004 National Health and Nutrition Examination Survey data for persons aged 12-19 years (N = 1,225). PA and ST were measured objectively by an accelerometer, and the American Heart Association Healthy Diet Score quantified diet quality. Maximal oxygen consumption (VËO2âmax) was measured by submaximal treadmill exercise test. We performed cluster analysis to identify sex-specific clustering of diet, PA, and ST. Adjusting for accelerometer wear time, age, body mass index, race/ethnicity, and the poverty-to-income ratio, we performed sex-stratified linear regression analysis to evaluate the association of cluster with VËO2âmax. RESULTS: Three clusters were identified for girls and boys. For girls, there was no difference across clusters for age (p = .1), weight (p = .3), and BMI (p = .5), and no relationship between clusters and VËO2âmax. For boys, the youngest cluster (p < .01) had three healthy behaviors, weighed less, and was associated with a higher VËO2âmax compared with the two older clusters. CONCLUSIONS: We observed clustering of diet, PA, and ST in U.S. adolescents. Specific patterns were associated with lower VËO2âmax for boys, suggesting that our clusters may help identify adolescent boys most in need of interventions.

Sedentary time (ST) and neighborhood environment (NE) are predictors of cardiovascular (CV) health. However, little is known about ST's relationship with NE. We examined associations of perceived and objective NE with ST in the predominantly African American faith-based population of the Washington, D.C. CV Health and Needs Assessment. After using community-based research principles, participants reported NE perceptions, including sidewalks, recreational areas, and crime presence. Factor analysis was conducted to explore pertinent constructs; factor sums were created and combined as Total Perception Score (TPS) (higher score = more favorable perception). Objective NE was assessed using Google Maps and the Active Neighborhood Checklist (ANC). ST was self-reported. Linear regression determined relationships between TPS and ST, and ANC scores and ST, for 1) overall population, 2) lower median-income D.C. areas, and 3) higher median-income DC and Maryland areas. For the sample (N = 98.9% African-American, 78% female), lower median-income areas had significantly lower mean TPS and ANC scores than higher median-income areas (p < 0.001). Three factors (neighborhood violence, physical/social environment, and social cohesion) were associated with overall NE perception. Among those in lower median-income areas, there was a negative association between TPS and ST that remained after covariate adjustment; this was not observed in higher median-income areas. There was no association between ANC scores and ST. Poorer NE perception is associated with greater ST for those in lower income areas, while objective environment is not related to ST. Multi-level interventions are needed to improve NE perceptions in lower-median income areas, reduce ST, and improve CV health.
ABSTRACT
OBJECTIVE: The objective of this study was to quantify the impact of crime on physical activity location accessibility, leisure-time physical activity (LTPA), and obesity among African American women. METHODS: An agent-based model was developed in 2016 to represent resource-limited Washington, DC, communities and their populations to simulate the impact of crime on LTPA and obesity among African American women under different circumstances. RESULTS: Data analysis conducted between 2016 and 2017 found that in the baseline scenario, African American women had a 25% probability of exercising. Reducing crime so more physical activity locations were accessible (increasing from 10% to 50%) decreased the annual rise in obesity prevalence by 2.69%. Increasing the probability of African American women to exercise to 37.5% further increased the impact of reducing crime on obesity (2.91% annual decrease in obesity prevalence). CONCLUSIONS: These simulations showed that crime may serve as a barrier to LTPA. Reducing crime and increasing propensity to exercise through multilevel interventions (i.e., economic development initiatives to increase time available for physical activity and subsidized health care) may promote greater than linear declines in obesity prevalence. Crime prevention strategies alone can help prevent obesity, but combining such efforts with other ways to encourage physical activity can yield even greater benefits.

Optimization of existing measurement tools is necessary to explore links between aspects of the neighborhood built environment and health behaviors or outcomes. We evaluate a scoring method for virtual neighborhood audits utilizing the Active Neighborhood Checklist (the Checklist), a neighborhood audit measure, and assess street segment representativeness in low-income neighborhoods. Eighty-two home neighborhoods of Washington, D.C. Cardiovascular Health/Needs Assessment (NCT01927783) participants were audited using Google Street View imagery and the Checklist (five sections with 89 total questions). Twelve street segments per home address were assessed for (1) Land-Use Type; (2) Public Transportation Availability; (3) Street Characteristics; (4) Environment Quality and (5) Sidewalks/Walking/Biking features. Checklist items were scored 0-2 points/question. A combinations algorithm was developed to assess street segments' representativeness. Spearman correlations were calculated between built environment quality scores and Walk Score®, a validated neighborhood walkability measure. Street segment quality scores ranged 10-47 (Mean = 29.4 ± 6.9) and overall neighborhood quality scores, 172-475 (Mean = 352.3 ± 63.6). Walk scores® ranged 0-91 (Mean = 46.7 ± 26.3). Street segment combinations' correlation coefficients ranged 0.75-1.0. Significant positive correlations were found between overall neighborhood quality scores, four of the five Checklist subsection scores, and Walk Scores® (r = 0.62, p < 0.001). This scoring method adequately captures neighborhood features in low-income, residential areas and may aid in delineating impact of specific built environment features on health behaviors and outcomes.

Body size and development time are important life history traits because they are often highly correlated with fitness. Although the developmental mechanisms that control growth have been well studied, the mechanisms that control how a species-characteristic body size is achieved remain poorly understood. In insects adult body size is determined by the number of larval molts, the size increment at each molt, and the mechanism that determines during which instar larval growth will stop. Adult insects do not grow, so the size at which a larva stops growing determines adult body size. Here we develop a quantitative understanding of the kinetics of growth throughout larval life of Manduca sexta, under different conditions of nutrition and temperature, and for genetic strains with different adult body sizes. We show that the generally accepted view that the size increment at each molt is constant (Dyar's Rule) is systematically violated: there is actually a progressive increase in the size increment from instar to instar that is independent of temperature. In addition, the mass-specific growth rate declines throughout the growth phase in a temperature-dependent manner. We show that growth within an instar follows a truncated Gompertz trajectory. The critical weight, which determines when in an instar a molt will occur, and the threshold size, which determines which instar is the last, are different in genetic strains with different adult body sizes. Under nutrient and temperature stress Manduca has a variable number of larval instars and we show that this is due to the fact that more molts at smaller increments are taken before threshold size is reached. We test whether the new insight into the kinetics of growth and size determination are sufficient to explain body size and development time through a mathematical model that incorporates our quantitative findings.
