Purpose: Investigate if the type of substance use disorder (SUD) in adolescence predicts SUDs in adulthood and examine sex and racial/ethnic differences in the persistence of SUDs., Methods: Data are from the Northwestern Juvenile Project, a 15-year longitudinal study of 1829 youth randomly sampled from detention in Chicago, IL (1995-1998). Interviewers assessed SUDs using structured diagnostic interviews., Results: Compared with females without an SUD at detention, females with cannabis alone, comorbid alcohol and cannabis, or SUDs other than alcohol and cannabis at detention had higher odds of having an SUD 5 years later (25%, 32%, and 36% vs. 15%, adjusted odds ratio [AOR] = 1.94, 95% confidence interval [CI] 1.11-3.40; AOR = 2.76, 95% CI 1.58-4.83; AOR = 3.46, 95% CI 1.56-7.66, respectively). Males and females with SUDs other than alcohol and cannabis at detention had greater odds of having an SUD 15 years later, compared with those without an SUD at detention (males: 36% vs. 14%, AOR = 2.98, 95% CI 1.14-7.83; females: 29% vs. 8%, AOR = 4.77, 95% CI 1.85-12.30). Among youth with an SUD at detention, males were more likely than females to have an SUD 15 years later (AOR = 1.84, 95% CI 1.03-3.29); non-Hispanic White and Hispanic males were more likely to persist than Black males (AOR = 3.32, 95% CI 1.50-7.35; AOR = 2.32, 95% CI 1.04-5.18, respectively)., Discussion: The type of SUD during adolescence matters. Youth with SUDs such as cocaine and opioids fared the worst. Healthcare providers must collaborate with correctional officials to increase service provision., (Copyright © 2024 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Introduction: To better understand and prevent research errors, we conducted a first-of-its-kind scoping review of clinical and translational research articles that were retracted because of problems in data capture, management, and/or analysis., Methods: The scoping review followed a preregistered protocol and used retraction notices from the Retraction Watch Database in relevant subject areas, excluding gross misconduct. Abstracts of original articles published between January 1, 2011 and January 31, 2020 were reviewed to determine if articles were related to clinical and translational research. We reviewed retraction notices and associated full texts to obtain information on who retracted the article, types of errors, authors, data types, study design, software, and data availability., Results: After reviewing 1,266 abstracts, we reviewed 884 associated retraction notices and 786 full-text articles. Authors initiated the retraction over half the time (58%). Nearly half of retraction notices (42%) described problems generating or acquiring data, and 28% described problems with preparing or analyzing data. Among the full texts that we reviewed: 77% were human research; 29% were animal research; and 6% were systematic reviews or meta-analyses. Most articles collected data de novo (77%), but only 5% described the methods used for data capture and management, and only 11% described data availability. Over one-third of articles (38%) did not specify the statistical software used., Conclusions: Authors may improve scientific research by reporting methods for data capture and statistical software. Journals, editors, and reviewers should advocate for this documentation. Journals may help the scientific record self-correct by requiring detailed, transparent retraction notices., Competing Interests: None., (© The Author(s) 2024.)

Objective: Hypertensive disorders of pregnancy (HDP) impact 10% of pregnancies in the United States and cause adverse maternal and neonatal outcomes such as prematurity and low birth weight. Aspirin administration to at-risk individuals during pregnancy can reduce risk of HDP., Study Design: Define-Measure-Assess-Improve-Control methodology was utilized to improve aspirin screening in an outpatient obstetric clinic. Retrospective cohort analysis compared outcome metrics pre- and postimplementation by using logistic regression models, adjusting for race and insurance. Key informant interviews and process mapping identified barriers to aspirin screening. A multidisciplinary team implemented low-cost strategies such as provider education, additional screening by ancillary staff, automated electronic reminders, and standardized patient counseling., Results: Over 6 months, the screening rate improved from 62.5 to 92.0% (adjusted odds ratio [aOR] = 6.89, 95% confidence interval [CI]: 3.30-14.43). The prescription rate for patients correctly identified to be eligible for aspirin improved from 66.7 to 82.4% (aOR = 1.96, 95% CI: 0.88-4.35)., Conclusion: Comprehensive, tailored quality improvement efforts can significantly increase aspirin screening and prescription, which may decrease maternal and neonatal morbidity due to HDP., Key Points: · Initiative improved overall and correct screening rates.. · Initiative increased provider knowledge of eligibility.. · Low-cost interventions can have high impact over short time interval.., Competing Interests: None declared., (Thieme.

Objective: To examine: (1) if youth who have mental health disorders receive needed services after they leave detention-and as they age; and (2) inequities in service use, focusing on demographic characteristics and type of disorder., Method: We used data from the Northwestern Juvenile Project, a longitudinal study of 1,829 youth randomly sampled from detention in Chicago, Illinois in 1995. Participants were re-interviewed up to 13 times through 2015. Interviewers assessed disorders using structured diagnostic interviews and assessed service use using the Child and Adolescent Service Assessment and the Services Assessment for Children and Adolescents., Results: Less than 20% of youth who needed services received them, up to median age 32 years. Female participants with any disorder had nearly twice the odds of receiving services compared with male participants (OR: 1.82; 95% CI: 1.41, 2.35). Compared with Black participants with any disorder, non-Hispanic White and Hispanic participants had 2.14 (95% CI: 1.57, 2.90) and 1.50 (95% CI: 1.04, 2.15) times the odds of receiving services. People with a disorder were more likely to receive services during childhood (< age 18) than during adulthood (OR: 2.29; 95% CI: 1.32, 3.95). Disorder mattered: participants with an internalizing disorder had 2.26 times and 2.43 times the odds of receiving services compared with those with a substance use disorder (respectively, 95% CI: 1.26, 4.04; 95% CI: 1.49, 3.97)., Conclusion: Few youth who need services receive them as they age; inequities persist over time. We must implement evidence-based strategies to reduce barriers to services., (Copyright © 2023 American Academy of Child and Adolescent Psychiatry. Published by Elsevier Inc. All rights reserved.)

Purpose: To examine the association between substance use disorders (SUDs) and HIV/AIDS risk behaviors in detained youth as they age., Methods: Prospective longitudinal study of a stratified random sample of 1,829 youth aged 10 to 18 years at baseline, sampled between November 1995 and June 1998 from the Cook County Juvenile Temporary Detention Center, Chicago, Illinois, and reinterviewed up to 13 times (to median age 32); 17,766 interviews overall., Results: Youth had greater odds of engaging in every risk behavior when they had an SUD compared with when they did not have an SUD. For example, SUD was associated with condomless vaginal sex with a high-risk partner (OR: 2.28, 95% CI: 1.84-2.82). SUD was also associated with multiple partners, although the strength varied by time and sex (e.g., 16 years after baseline, OR: 3.58, 95% CI: 2.46-5.23 females; OR: 2.07, 95% CI: 1.48-2.88 males). Types of SUD-alcohol, comorbid alcohol and marijuana, drugs other than marijuana-were also associated with HIV/AIDS risk behaviors., Discussion: SUDs and HIV/AIDS risk behaviors are linked among youth in the juvenile justice system and as they age. There is a longstanding need for targeted and integrated HIV and SUD services, but this need remains unmet., (Copyright © 2023 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Importance: Youths, especially Black and Hispanic males, are disproportionately affected by firearm violence. Yet, no epidemiologic studies have examined the incidence rates of nonfatal firearm injury and firearm mortality in those who may be at greatest risk-youths who have been involved with the juvenile justice system., Objectives: To examine nonfatal firearm injury and firearm mortality in youths involved with the juvenile justice system and to compare incidence rates of firearm mortality with the general population., Design, Setting, and Participants: The Northwestern Juvenile Project is a 25-year prospective longitudinal cohort study of 1829 youths after juvenile detention in Chicago, Illinois. Youths were randomly sampled by strata (sex, race and ethnicity, age, and legal status [juvenile or adult court]) at intake from the Cook County Juvenile Temporary Detention Center. Participants were interviewed at baseline (November 1995 to June 1998) and reinterviewed as many as 13 times over 16 years, through February 2015. Official records on mortality were collected through December 2020. Data analysis was conducted from November 2018 to August 2022., Main Outcomes and Measures: Participants self-reported nonfatal firearm injuries. Firearm deaths were identified from county and state records and collateral reports. Data on firearm deaths in the general population were obtained from the Illinois Department of Public Health. Population counts were obtained from the US census., Results: The baseline sample of 1829 participants included 1172 (64.1%) males and 657 (35.9%) females; 1005 (54.9%) Black, 524 (28.6%) Hispanic, 296 (16.2%) non-Hispanic White, and 4 (0.2%) from other racial and ethnic groups (mean [SD] age, 14.9 [1.4] years). Sixteen years after detention, more than one-quarter of Black (156 of 575 [27.1%]) and Hispanic (103 of 387 [26.6%]) males had been injured or killed by firearms. Males had 13.6 (95% CI, 8.6-21.6) times the rate of firearm injury or mortality than females. Twenty-five years after the study began, 88 participants (4.8%) had been killed by a firearm. Compared with the Cook County general population, most demographic groups in the sample had significantly higher rates of firearm mortality (eg, rate ratio for males, 2.8; 95% CI, 2.0-3.9; for females: 6.5; 95% CI, 3.0-14.1; for Black males, 2.5; 95% CI, 1.7-3.7; for Hispanic males, 9.6; 95% CI, 6.2-15.0; for non-Hispanic White males, 23.0; 95% CI, 11.7-45.5)., Conclusions and Relevance: This is the first study to examine the incidence of nonfatal firearm injury and firearm mortality in youths who have been involved with the juvenile justice system. Reducing firearm injury and mortality in high-risk youths and young adults requires a multidisciplinary approach involving legal professionals, health care professionals, educators, street outreach workers, and public health researchers.

The organizational structures of collaborative biostatistics units in academic health centers (AHCs) in the United States and their important contributions to research are an evolving and active area of discussion and inquiry. Collaborative biostatistics units may serve as a centralized resource to investigators across various disciplines or as shared infrastructure for investigators within a discipline (e.g., cancer), or a combination of both. The characteristics of such units vary greatly, and there has been no comprehensive review of their organizational structures described in the literature to date. This manuscript summarizes the current infrastructure of such units using responses from 129 leaders. Most leaders were over 45 years old, held doctoral degrees, and were on a 12-month appointment. Over half were tenured or on a tenure track and held primary appointments in a school of medicine. Career advancement metrics most important included being funded as co-investigator on NIH grants and being either first or second author on peer-reviewed publications. Team composition was diverse in terms of expertise and training, and funding sources were typically hybrid. These results provide a benchmark for collaboration models and evaluation and may be used by institutional administrators as they build, evaluate, or restructure current collaborative quantitative support infrastructure., Competing Interests: The authors have no conflicts of interest to declare., (© 2022 The Authors.

Importance: Previous studies have found that one-half to three-quarters of youths detained in juvenile justice facilities have 1 or more psychiatric disorders. Little is known about the course of their disorders as they age., Objective: To examine the prevalence, comorbidity, and continuity of 13 psychiatric disorders among youths detained in a juvenile justice facility during the 15 years after detention up to a median age of 31 years, with a focus on sex and racial/ethnic differences., Design, Setting, and Participants: The Northwestern Juvenile Project is a longitudinal cohort study of health needs and outcomes of 1829 randomly selected youths in a temporary juvenile detention center in Cook County, Illinois. Youths aged 10 to 18 years were interviewed in detention from November 20, 1995, through June 14, 1998. Participants were reinterviewed up to 12 times during the 15-year study period through February 2015, for a total of 16 372 interviews. The sample was stratified by sex, race/ethnicity (Black, Hispanic, and non-Hispanic White), age (10-13 years or 14-18 years), and legal status (processed in juvenile or adult court). Data analysis was conducted from February 2014, when data preparation began, to March 2020., Exposures: Detention in a juvenile justice facility., Main Outcomes and Measures: Psychiatric disorders, assessed by the Diagnostic Interview Schedule for Children, version 2.3 at the baseline interviews. Follow-up interviews were conducted using the Diagnostic Interview Schedule for Children, version IV; the Diagnostic Interview Schedule, version IV; and the World Mental Health Composite International Diagnostic Interview (beginning at the 6-year follow-up interview)., Results: The study included 1829 youths sampled at baseline (1172 males and 657 females; mean [SD] age, 14.9 [1.4] years). Although prevalence and comorbidity of psychiatric disorders decreased as the 1829 participants aged, 52.3% of males and 30.9% of females had at least 1 or more psychiatric disorders 15 years postdetention. Among participants with a disorder at baseline, 64.3% of males and 34.8% of females had a disorder 15 years later. Compared with females, males had 3.37 times the odds of persisting with a psychiatric disorder 15 years after baseline (95% CI, 1.79-6.35). Compared with Black participants and Hispanic participants, non-Hispanic White participants had 1.6 times the odds of behavioral disorders (odds ratio, 1.56; 95% CI, 1.27-1.91 and odds ratio, 1.59; 95% CI, 1.23-2.05, respectively) and greater than 1.3 times the odds of substance use disorders (odds ratio, 1.90; 95% CI, 1.55-2.33 and odds ratio, 1.39; 95% CI, 1.11-1.73, respectively) throughout the follow-up period. Behavioral disorders and substance use disorders were the most prevalent 15 years after detention., Conclusions and Relevance: This study's findings suggest that persistent psychiatric disorders may complicate the transition from adolescence to adulthood, which is already challenging for youths involved in the juvenile justice system, many of whom are from racial/ethnic minority groups and low-income backgrounds. The pediatric health community should advocate for early identification and treatment of disorders among youths in the justice system.

Introduction: Takotsubo syndrome (TTS) is an acute heart failure syndrome that leads to significant morbidity and mortality. We sought to evaluate the association of cardiac mechanics on presentation with in-hospital adverse outcomes in patients with apical TTS., Methods: We retrospectively identified 468 patients with TTS based on ICD-9/10 codes between 2006 and 2017. The association of echocardiographic parameters with a composite outcome of heart failure and all-cause mortality during the index hospitalization was analyzed., Results: One hundred and forty one patients with the apical subtype and adequate imaging were included. 113 (80.1%) were female, left ventricular ejection fraction (LVEF) was 41.7% ± 12.4%, and global longitudinal strain was -10.1% ± 3.2%. The composite outcome occurred in 58 patients (41%), with heart failure occurring in 55 patients and death occurring in nine patients. Global longitudinal strain, global circumferential strain, global radial strain, right ventricular fractional area change, tricuspid annular plane systolic excursion, and right ventricular free wall strain were significantly worse in patients who experienced the composite outcome in univariate analyses. However, only LVEF was independently associated with the composite outcome in multivariable-adjusted analysis., Conclusions: In patients with apical TTS, the strain has limited prognostic utility in the acute setting compared to LVEF, which was the only echocardiographic parameter associated with in-hospital heart failure and all-cause mortality., (© 2021 Wiley Periodicals LLC.)

Importance: Preventing firearm violence requires understanding its antecedents. Yet no comprehensive longitudinal study has examined how involvement with firearms during adolescence-use, access, and victimization (defined as threatened with a weapon or gunshot injury)-is associated with the perpetration of firearm violence in adulthood., Objective: To examine the association between firearm involvement during adolescence and subsequent firearm perpetration and ownership in adulthood among youth involved in the juvenile justice system., Design, Setting, and Participants: This cohort study analyzed interview responses of 1829 randomly selected participants as part of the Northwestern Juvenile Project, a longitudinal study of health needs and outcomes of youth sampled from a temporary juvenile detention center in a large US city. Youth aged 10 to 18 years were interviewed in detention from November 1995 through June 1998. Participants were reinterviewed up to 13 times over 16 years through February 2015, for a total of 17 776 interviews. The sample was stratified by sex, race/ethnicity, age, and legal status (juvenile or adult court). Data were analyzed from April 2017, when data preparation began, through November 2020., Exposures: Firearm involvement during adolescence: use (ie, threaten, shoot), access (ownership, ease of access, firearm in household, membership in gang that carries firearms), and victimization (gunshot injury, threatened with a weapon)., Main Outcomes and Measures: Firearm involvement during adulthood: perpetration of firearm violence (ie, threatening with or using a firearm) and firearm ownership., Results: Among the 1829 participants, 1388 had a 16-year follow-up interview: 860 males, 528 females; 809 were African American, 203 were non-Hispanic White; 374 were Hispanic; and 2 were other race/ethnicity; median (interquartile range) age of 32 (30-32) years. Eighty-five percent of males and 63.2% of females were involved with firearms as adolescents. Compared with females, males had significantly higher odds of every type of involvement except having a firearm in the home. In adulthood, 41.3% of males and 10.5% of females perpetrated firearm violence. Adolescents who had been threatened with a weapon or injured by firearms had 3.1 (95% CI, 2.0-4.9) and 2.4 (95% CI, 1.2-4.9) times the odds of perpetrating violence during adulthood. Similar associations were found for firearm ownership., Conclusions and Relevance: Involvement with firearms during adolescence-including victimization-is a significant risk factor for firearm perpetration and ownership during adulthood.

Patch clamp recording enabled a revolution in cellular electrophysiology, and is useful for evaluating the functional consequences of ion channel gene mutations or variants associated with human disorders called channelopathies. However, due to massive growth of genetic testing in medical practice and research, the number of known ion channel variants has exploded into the thousands. Fortunately, automated methods for performing patch clamp recording have emerged as important tools to address the explosion in ion channel variants. In this chapter, we present our approach to harnessing automated electrophysiology to study a human voltage-gated potassium channel gene (KCNQ1), which harbors hundreds of mutations associated with genetic disorders of heart rhythm including the congenital long-QT syndrome. We include protocols for performing high efficiency electroporation of heterologous cells with recombinant KCNQ1 plasmid DNA and for automated planar patch recording including data analysis. These methods can be adapted for studying other voltage-gated ion channels., (Copyright © 2021 Elsevier Inc. All rights reserved.)

The cost of prescription drugs has increased at rates far exceeding general inflation in recent history, with topical drugs increasing at a disproportionate rate compared to other routes of administration. We assessed the relationship between net changes in the number of therapeutic options, defined as any approved drug or therapeutic equivalent on the market, and prescription topical drug spending. Drugs were divided based on the category of use through pairing of Medicare Part D Prescriber Public Use and Food and Drug Administration (FDA) approved drug products databases. Across drug classes, we modeled the log of the ratio of total spending per unit in 2015 to total spending per unit in 2011 as a linear function of net number of topical therapeutic options over this time period. Primary outcomes include total Medicaid Part D spending on topical drugs and net change in the number of available therapeutic options within each category of use. Total spending on topical drugs increased by 61%, while the number of units dispensed increased by only 18% from 2011-2015. The greatest total spending increases were in categories with few new therapeutic options, such as topical corticosteroid and antifungal medications. Each net additional therapeutic option during 2011-2015 was associated with an reduction in how much relative spending per unit increased (95% CI 2.5%-14.4%, p = 0.013). Stimulating greater competition through increasing the net number of therapeutic options within each major topical category of use may place downward pressure on topical prescription drug spending under medicare Part D.

Within the Biostatistics, Epidemiology, and Research Design (BERD) component of the Northwestern University Clinical and Translational Sciences Institute, we created a mentoring program to complement training provided by the associated Multidisciplinary Career Development Program (KL2). Called Research design Analysis Methods Program (RAMP) Mentors, the program provides each KL2 scholar with individualized, hands-on mentoring in biostatistics, epidemiology, informatics, and related fields, with the goal of building multidisciplinary research teams. From 2015 to 2019, RAMP Mentors paired 8 KL2 scholars with 16 individually selected mentors. Mentors had funded/protected time to meet at least monthly with their scholar to provide advice and instruction on methods for ongoing research, including incorporating novel techniques. RAMP Mentors has been evaluated through focus groups and surveys. KL2 scholars reported high satisfaction with RAMP Mentors and confidence in their ability to establish and maintain methodologic collaborations. Compared with other Northwestern University K awardees, KL2 scholars reported higher confidence in obtaining research funding, including subsequent K or R awards, and selecting appropriate, up-to-date research methods. RAMP Mentors is a promising partnership between a BERD group and KL2 program, promoting methodologic education and building multidisciplinary research teams for junior investigators pursuing clinical and translational research., Competing Interests: The authors have no conflicts of interest to declare., (© The Association for Clinical and Translational Science 2020.)

Objective: To describe trends in the characteristics of urologic surgeons performing vasectomy over time., Methods: We performed a retrospective, cross-sectional study examining surgeon characteristics for case logs from the American Board of Urology between 2004 and 2013. We used generalized estimating equations with a log link and negative binomial distribution to examine demographic differences (gender, rural location, and surgeon volume) in the number of vasectomies surgeons performed over time., Results: Between 2004 and 2013, 5316 urologists had case logs collected within the 7-month certification window. The majority of these surgeons self-identified as general urologists (82.8%), and a small proportion identified as andrology and infertility specialists (1.7%). Across all years, the median number of vasectomies performed per certifying surgeon during the study period was 14 (interquartile range 6-26). The majority of vasectomies were performed by high-volume surgeons (≥ 26 vasectomies) ranging from 49.2% to 66.9% annually, whereas the proportion performed by low-volume (≤ 5 vasectomies) surgeons ranged from 3.3% to 6.6% annually. Male surgeons performed vasectomies 2.20 times more frequently than female surgeons (95% confidence interval 1.93-2.49; P <.0001) across the study period with no evidence to suggest this gap changed over time (gender-year interaction 1.01 [95% confidence interval: 0.97-1.06; p = .576])., Conclusion: While the majority of urologists performing vasectomy identify as general urologists, there appears to be a focus on vasectomy practice among a small number of high-volume surgeons. Furthermore, while the number of female surgeons performing vasectomies increased, a gender gap persists in the proportion of vasectomies performed by females., (Copyright © 2020 Elsevier Inc.

Background: Structural left atrial and ventricular abnormalities on the electrocardiogram (ECG) and transthoracic echocardiogram (TTE) at the time of ischemic stroke have been associated with morbidity and mortality. Yet, the prognostic impact of the same in embolic stroke of undetermined source (ESUS), a relevant subtype of ischemic stroke with a unique pathophysiology, has not been well studied to date. Our aim was to assess the predictive impact of left atrio-ventricular ECG and TTE abnormalities on one-year hospital readmission after ESUS from an ongoing single center prospective stroke registry in the U.S., Methods: We identified 369 ESUS patients who had at least 1 year of complete follow-up between 2013 and 2018. We examined the association of abnormal left atrio-ventricular findings on ECG and TTE, as well as basic demographic and clinical characteristics, measured at index admission with time to 1-year hospital readmission using Kaplan-Meier curves, log-rank tests, and Cox proportional hazards regression., Results: Recurrent ischemic stroke and cardiovascular causes constituted 60% of all readmissions. Patients with left atrial dilation on TTE were more likely to readmitted within 1 year (HR 1.51; 95% CI, 1.04-2.21). Bundle branch block, pathologic Q-wave, and troponin elevation curves diverged, but were not significantly associated with readmission (log-rank p=0.34, p=0.08, p=0.42, respectively)., Conclusions: Following ESUS, left atrial dilation on TTE was associated with 1-year overall hospital readmission, of which cardiovascular and cerebrovascular ischemic events, and heart failure were a notable proportion. Our data support ongoing studies of atrial cardiopathy in ESUS patients., Competing Interests: Declaration Competing of Interest None, (Copyright © 2020 Elsevier Inc. All rights reserved.)

Introduction: Statistical literacy is essential in clinical and translational science (CTS). Statistical competencies have been published to guide coursework design and selection for graduate students in CTS. Here, we describe common elements of graduate curricula for CTS and identify gaps in the statistical competencies., Methods: We surveyed statistics educators using e-mail solicitation sent through four professional organizations. Respondents rated the degree to which 24 educational statistical competencies were included in required and elective coursework in doctoral-level and master's-level programs for CTS learners. We report competency results from institutions with Clinical and Translational Science Awards (CTSAs), reflecting institutions that have invested in CTS training., Results: There were 24 CTSA-funded respondents representing 13 doctoral-level programs and 23 master's-level programs. For doctoral-level programs, competencies covered extensively in required coursework for all doctoral-level programs were basic principles of probability and hypothesis testing, understanding the implications of selecting appropriate statistical methods, and computing appropriate descriptive statistics. The only competency extensively covered in required coursework for all master's-level programs was understanding the implications of selecting appropriate statistical methods. The least covered competencies included understanding the purpose of meta-analysis and the uses of early stopping rules in clinical trials. Competencies considered to be less fundamental and more specialized tended to be covered less frequently in graduate courses., Conclusion: While graduate courses in CTS tend to cover many statistical fundamentals, learning gaps exist, particularly for more specialized competencies. Educational material to fill these gaps is necessary for learners pursuing these activities., (© The Association for Clinical and Translational Science 2020.)

Key Points: The activity of local excitatory circuits of the subiculum has been suggested to be involved in the initiation of pathological activity in epileptic patients and experimental animal models of temporal lobe epilepsy. We have taken advantage of multimodal techniques to classify subicular cells in distinct subclasses and have investigated their morphofunctional properties and connectivity in vitro. Our results indicate that local subicular excitatory circuits are connected in a cell type-specific fashion and that synapses are preferentially established on basal vs. apical dendrites. We show that local excitatory circuits, isolated from extrasubicular inputs and pharmacologically disinhibited, are sufficient to initiate synchronous epileptiform activity in vitro. In conclusion, this work provides a high-resolution description of local excitatory circuits of the subiculum and highlights their mechanistic involvement in the generation of pathological activity., Abstract: The subiculum has been suggested to be involved in the initiation of pathological discharges in human patients and animal models of temporal lobe epilepsy. Although converging evidence has revealed the existence of functional diversity within its principal neurons, much less attention has been devoted to its intrinsic connectivity and whether its local excitatory circuits are sufficient to generate epileptiform activity. Here, we have directly addressed these two key points in mouse subicular slices. First, using multivariate techniques, we have distinguished two groups of principal cells, which we have termed type 1 and type 2. These subgroups roughly overlap with what were classically indicated as regular and bursting cells, and showed differences in the extension and complexity of their apical dendrites. Functional connectivity was found both between similar (homotypic) and different (heterotypic) types of cells, with a marked asymmetry within heterotypic pairs. Unitary excitatory postsynaptic potentials (uEPSPs) revealed a high degree of variability both in amplitude, failure rate, rise time and half-width. Post hoc analysis of functionally connected pairs suggested that the observed uEPSPs were mediated by few contact sites, predominantly located on the basal dendrites. When surgically isolated from extrasubicular excitatory afferents, pharmacologically disinhibited subicular slices generated hyper-synchronous discharges. Thus, we conclude that local subicular excitatory circuits, connected according to cell type-specific rules, are sufficient to promote epileptiform activity. This conclusion fits well with a previous suggestion that local subicular events, purely mediated by excitatory connections, may underlie the pre-ictal discharges that govern interictal-ictal transitions., (© 2020 The Authors.

Purpose: Patients often receive antibiotic prophylaxis after urethroplasty to minimize the risk of urinary tract infection (UTI). The aim of this study was to determine the frequency of UTIs after urethroplasty and its impact on urethral and incisional healing., Methods: Patients undergoing urethroplasty by a single surgeon from 2000 to 2012 were retrospectively reviewed. All patients received preoperative antibiotic prophylaxis and postoperative prophylaxis for 30 days or until catheter removal. We reviewed urine cultures obtained within 30 days after urethroplasty in symptomatic patients, and rates of stricture recurrence and wound complications. A positive culture was defined as > 1000 cfu/mL of an organism., Results: 398 patients were included with a mean age of 43.5 years at time of surgery. We identified 102 positive urine cultures (25.6%) within 30 days of urethroplasty. 78 stricture recurrences (19.6%) occurred at an average of 3 years after surgery and 18 (4.5%) experienced a wound complication, with a 52 month mean follow-up. There were no significant differences in stricture recurrence (p = 0.36) or wound complications (p = 0.42) between patients who had a positive and negative urine culture. On multivariate analysis, positive urine cultures (HR 1.0, 95% CI 0.6-1.8, p = 0.88) were not associated with stricture recurrence, while lichen sclerosis (HR 3.2, 95% CI 1.1-9.2, p = 0.03) and previous urethroplasty (HR 2.3, 95% CI 1.1-4.6, p = 0.03) were., Conclusion: Bacterial colonization and UTIs despite antimicrobial prophylaxis are common in urethroplasty patients. This, however, does not appear to impair urethral healing or influence wound healing, suggesting that postoperative prophylaxis may in fact offer no benefit.

Eating disorders cause a number of severely impairing symptoms that may require more intensive intervention that is available through outpatient therapy services. The PHP/IOP level of care may be an effective mode of treatment in these cases, but few studies have examined overall outcomes or treatment moderators for this level of care. Using a large sample from a PHP/IOP specifically designed for the treatment of eating disorders, the current study examines a variety of symptoms (eating disorder severity, quality of life, depression, etc.) from admission to discharge, as well as potential moderators of treatment, including demographic and clinical factors. Overall, the PHP/IOP level of care was found to improve treatment outcomes. Age, race, gender, and depression were found to moderate the change in quality of life and functional impairment. Additionally, patients diagnosed with anorexia nervosa had significantly lowered quality of life and greater eating disorder symptomatology than all other diagnoses. The results of this study can help to inform clinical practice and help guide in treatment decisions at the partial hospitalization level of care.

Importance: Residency applicants often use social media to discuss the positive and negative features of prospective training programs. An examination of the content discussed by applicants could provide guidance for how a medical education faculty can better engage with prospective trainees and adapt to meet the educational expectations of a new generation of digital-native physicians., Objective: The objective was to identify unstructured social media data submitted by residency applicants and categorize positive and negative statements to determine key themes., Design: The study design was qualitative analysis of a retrospective cohort., Setting: Publicly available datasets were used., Participants: The participants were anonymized medical trainees applying to residency training positions in 9 specialties-dermatology, general surgery, internal medicine, obstetrics/gynecology, plastic surgery, otolaryngology, physical medicine and rehabilitation, pediatrics, and radiology-from 2007 to 2017., Main Outcomes and Measures: After we developed a standardized coding scheme that broke comments down into major features, themes, and subthemes, all unstructured comments were coded by two independent researchers. Positive and negative comments were coded separately. Frequency counts and percentages were recorded for each identified feature, theme, and subtheme. The percent positive and negative comments by specialty were also calculated., Results: Of the 6314 comments identified, 4541 were positive and 1773 were negative. Institution was the most commonly cited major feature in both the positive (n = 767 [17%]) and negative (n = 827 [47%]) comments. Geography was the most cited theme, and City, Cost of Living, and Commute were commonly cited subthemes. Training was the next most cited major feature in both positive (n = 1005 [22%]) and negative (n = 291 [16%]) comments, with Clinical Training being more commonly cited compared to Research Opportunities. Overall, 72% of comments from all were positive; however, the percent of comments that were positive comments varied significantly across the 9 specialties. Pediatrics (65%), dermatology (66%), and internal medicine (68%) applicants were more likely to express negative comments compared with the global average, but physical medicine and rehabilitation (85%), radiology (82%), otolaryngology (81%), and plastic surgery (80%) applicants were more likely to express positive comments., Conclusions and Relevance: This qualitative analysis of positive and negative themes as posted by applicants in recent matching years is the first and provides new detailed insights into the motivations and desires of trainees., (Copyright © 2018.

Supportive social networks are key to the successful transition to young adulthood. Yet, we know little about networks of delinquent youth, a population at risk for disrupted social connections. This study describes the structure and function of social support networks among delinquent youth eight years after detention; median age 24 years. Nearly one-fifth of participants had no one that they could count on, and one-third had only one person in their support network. Participants tended to have very dense networks composed almost entirely of family. Findings underscore the importance of expanding social supports for delinquent youth as they age.

Introduction: It is increasingly essential for medical researchers to be literate in statistics, but the requisite degree of literacy is not the same for every statistical competency in translational research. Statistical competency can range from 'fundamental' (necessary for all) to 'specialized' (necessary for only some). In this study, we determine the degree to which each competency is fundamental or specialized., Methods: We surveyed members of 4 professional organizations, targeting doctorally trained biostatisticians and epidemiologists who taught statistics to medical research learners in the past 5 years. Respondents rated 24 educational competencies on a 5-point Likert scale anchored by 'fundamental' and 'specialized.', Results: There were 112 responses. Nineteen of 24 competencies were fundamental. The competencies considered most fundamental were assessing sources of bias and variation (95%), recognizing one's own limits with regard to statistics (93%), identifying the strengths, and limitations of study designs (93%). The least endorsed items were meta-analysis (34%) and stopping rules (18%)., Conclusion: We have identified the statistical competencies needed by all medical researchers. These competencies should be considered when designing statistical curricula for medical researchers and should inform which topics are taught in graduate programs and evidence-based medicine courses where learners need to read and understand the medical research literature.

Importance: Longitudinal studies of delinquent youth have focused on criminal recidivism, not on psychosocial outcomes in adulthood. This omission is critical because after detention most youth return to the community, where they become the responsibility of pediatric health care professionals., Objective: To investigate 8 positive outcomes among delinquent youth 5 and 12 years after detention, focusing on sex and racial/ethnic differences., Design, Setting, and Participants: In the Northwestern Juvenile Project, a longitudinal US study of long-term outcomes of delinquent youth after detention, participants were interviewed in detention between November 20, 1995, and June 14, 1998, and reinterviewed up to 9 times during the 12-year study period, through May 12, 2011. Data analysis was conducted between November 18, 2013, and July 25, 2016., Exposures: Juvenile detention., Main Outcomes and Measures: Achievement of positive outcomes in 8 domains: educational attainment, residential independence, gainful activity, desistance from criminal activity, mental health, abstaining from substance abuse, interpersonal functioning, and parenting responsibility. Outcomes were assessed with widely used measures supplemented by correctional records., Results: The study included 1829 youth at baseline (1172 males and 657 females; mean [SD] age, 14.9 [1.4] years). At the end of the study, 1520 (83.1%) of the original sample remained (944 males and 576 females; mean [SD] age, 27.6 [1.4] years). Twelve years after detention, females were more likely than males to have positive outcomes for gainful activity (odds ratio [OR], 2.53; 95% CI, 1.86-3.44), desistance from criminal activity (OR, 5.89; 95% CI, 4.38-7.92), residential independence (OR, 3.41; 95% CI, 2.57-4.52), parenting responsibility (OR, 18.65; 95% CI, 12.29-28.30), and mental health (OR, 1.48; 95% CI, 1.13-1.92). Twelve years after detention, only 21.9% of males and 54.7% of females had achieved more than half of the outcomes. As youth aged, the number of positive outcomes increased only modestly (mean increase for males, 0.37; 95% CI, 0.13-0.62; for females, 0.29; 95% CI, 0.13-0.45). Among males, non-Hispanic white individuals were significantly more likely to achieve most positive outcomes compared with minorities, but less likely to abstain from substance abuse. For example, 12 years after detention, non-Hispanic white males had nearly 3 times the odds of educational attainment compared with African American (OR, 2.82; 95% CI, 1.77-4.50) and Hispanic males (OR, 2.91; 95% CI, 1.75-4.82), and 2 to 5 times the odds of gainful activity compared with African American (OR, 5.17; 95% CI, 3.16-8.45) and Hispanic males (OR, 2.58; 95% CI, 1.56-4.26). Latent class analysis shows that African American males fared the worst, with lives characterized by incarceration, criminal activity, and few positive outcomes., Conclusions and Relevance: Our findings highlight racial/ethnic disparities among youth in achieving positive outcomes after detention. To improve outcomes, pediatric health care professionals should recognize the importance of psychosocial health, partner with on-site psychosocial services in their practices, and facilitate access to services in the community.

Objective: To identify trajectories of substance use disorders (SUDs) in youth during the 12 years after detention and how gender, race/ethnicity, and age at baseline predict trajectories., Method: As part of the Northwestern Juvenile Project, a longitudinal study of 1,829 youth randomly sampled from detention in Chicago, Illinois from 1995 through 1998, participants were reinterviewed in the community or correctional facilities up to 9 times over 12 years. Independent interviewers assessed SUDs using the Diagnostic Interview Schedule for Children 2.3 (baseline) and the Diagnostic Interview Schedule IV (follow-ups). Primary outcome was a mutually exclusive 5-category typology of disorder: no SUD, alcohol alone, marijuana alone, comorbid alcohol and marijuana, or "other" illicit ("hard") drug. Trajectories were estimated using growth mixture models with a 3-category ordinal variable derived from the typology., Results: During the 12-year follow-up, 19.6% of youth did not have an SUD. The remaining 81.4% were in 3 trajectory classes. Class 1 (24.5%), a bell-shaped trajectory, peaked 5 years after baseline when 42.7% had an SUD and 12.5% had comorbid or "other" illicit drug disorders. Class 2 (41.3%) had a higher prevalence of SUD at baseline, 73.8%. Although prevalence decreased over time, 23.5% had an SUD 12 years later. Class 3 (14.6%), the most serious and persistent trajectory, had the highest prevalence of comorbid or "other" illicit drug disorders-52.1% at baseline and 17.4% 12 years later. Males, Hispanics, non-Hispanic whites, and youth who were older at baseline (detention) had the worst outcomes., Conclusion: Gender, race/ethnicity, and age at detention predict trajectories of SUDs in delinquent youth. Findings provide an empirical basis for child psychiatry to address health disparities and improve prevention., Competing Interests: Drs. Hershfield, Han, and Byck report no biomedical financial interests or potential conflicts of interest., (Copyright © 2016 American Academy of Child and Adolescent Psychiatry.

Objectives: To examine changes in the prevalence of 15 HIV/AIDS sex and drug risk behaviors in delinquent youth during the 14 years after they leave detention, focusing on sex and racial/ethnic differences., Methods: The Northwestern Juvenile Project, a prospective longitudinal study of 1829 youth randomly sampled from detention in Chicago, Illinois, recruited between 1995 and 1998 and reinterviewed up to 11 times. Independent interviewers assessed HIV/AIDS risk behaviors using the National Institutes on Drug Abuse Risk Behavior Assessment., Results: Fourteen years after detention (median age, 30 years), one-quarter of males and one-tenth of females had >1 sexual partner in the past 3 months. One-tenth of participants reported recent unprotected vaginal sex with a high-risk partner. There were many sex and racial/ethnic differences. For example, African American males had 4.67 times the odds of having >1 partner than African American females (95% confidence interval [CI], 3.22-6.76). Over time, compared with non-Hispanic white males, African American males had 2.56 times the odds (95% CI, 1.97-3.33) and Hispanic males had 1.63 times the odds (95% CI, 1.24-2.12) of having multiple partners, even after adjusting for incarceration and age. Non-Hispanic white females were more likely to have multiple partners than racial/ethnic minority females., Conclusions: Although rates decrease over time, prevalence of sex risk behaviors are much higher than the general population. Among males, racial/ethnic minorities were at particular risk. The challenge for pediatric health is to address how disproportionate confinement of racial/ethnic minority youth contributes to disparities in the HIV/AIDS epidemic., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2017 by the American Academy of Pediatrics.)

Purpose: To learn the size, composition, and scholarly output of biostatistics, epidemiology, and research design (BERD) units in U.S. academic health centers (AHCs)., Method: Each year for four years, the authors surveyed all BERD units in U.S. AHCs that were members of the Clinical and Translational Science Award (CTSA) Consortium. In 2010, 46 BERD units were surveyed; in 2011, 55; in 2012, 60; and in 2013, 61., Results: Response rates to the 2010, 2011, 2012, and 2013 surveys were 93.5%, 98.2%, 98.3%, and 86.9%, respectively. Overall, the size of BERD units ranged from 3 to 86 individuals. The median FTE in BERD units remained similar and ranged from 3.0 to 3.5 FTEs over the years. BERD units reported more availability of doctoral-level biostatisticians than doctoral-level epidemiologists. In 2011, 2012, and 2013, more than a third of BERD units provided consulting support on 101 to 200 projects. A majority of BERD units reported that between 25% and 75% (in 2011) and 31% to 70% (in 2012) of their consulting was to junior investigators. More than two-thirds of BERD units reported their contributions to the submission of 20 or more non-BERD grant or contract applications annually. Nearly half of BERD units reported 1 to 10 manuscripts submitted annually with a BERD practitioner as the first or corresponding author., Conclusions: The findings regarding BERD units provide a benchmark against which to compare BERD resources and may be particularly useful for institutions planning to develop new units to support programs such as the CTSA.

Objectives: To examine sex and racial/ethnic differences in the prevalence of 9 substance-use disorders (SUDs)--alcohol, marijuana, cocaine, hallucinogen or PCP, opiate, amphetamine, inhalant, sedative, and unspecified drug--in youths during the 12 years after detention., Methods: We used data from the Northwestern Juvenile Project, a prospective longitudinal study of 1829 youths randomly sampled from detention in Chicago, Illinois, starting in 1995 and reinterviewed up to 9 times in the community or correctional facilities through 2011. Independent interviewers assessed SUDs with Diagnostic Interview Schedule for Children 2.3 (baseline) and Diagnostic Interview Schedule version IV (follow-ups)., Results: By median age 28 years, 91.3% of males and 78.5% of females had ever had an SUD. At most follow-ups, males had greater odds of alcohol- and marijuana-use disorders. Drug-use disorders were most prevalent among non-Hispanic Whites, followed by Hispanics, then African Americans (e.g., compared with African Americans, non-Hispanic Whites had 32.1 times the odds of cocaine-use disorder [95% confidence interval = 13.8, 74.7])., Conclusions: After detention, SUDs differed markedly by sex, race/ethnicity, and substance abused, and, contrary to stereotypes, did not disproportionately affect African Americans. Services to treat substance abuse--during incarceration and after release--would reach many people in need, and address health disparities in a highly vulnerable population.

Criteria for evaluating faculty are traditionally based on a triad of scholarship, teaching, and service. Research scholarship is often measured by first or senior authorship on peer-reviewed scientific publications and being principal investigator on extramural grants. Yet scientific innovation increasingly requires collective rather than individual creativity, which traditional measures of achievement were not designed to capture and, thus, devalue. The authors propose a simple, flexible framework for evaluating team scientists that includes both quantitative and qualitative assessments. An approach for documenting contributions of team scientists in team-based scholarship, nontraditional education, and specialized service activities is also outlined. Although biostatisticians are used for illustration, the approach is generalizable to team scientists in other disciplines.The authors offer three key recommendations to members of institutional promotion committees, department chairs, and others evaluating team scientists. First, contributions to team-based scholarship and specialized contributions to education and service need to be assessed and given appropriate and substantial weight. Second, evaluations must be founded on well-articulated criteria for assessing the stature and accomplishments of team scientists. Finally, mechanisms for collecting evaluative data must be developed and implemented at the institutional level. Without these three essentials, contributions of team scientists will continue to be undervalued in the academic environment.

The authors investigated HIV knowledge change among a cohort of juvenile detainees. Participants completed an HIV knowledge survey at baseline and up to 4 more times over 6 years. The authors calculated knowledge scores; the time serial trend of scores was modeled using generalized estimating equations. A baseline survey was completed by 798 participants, ages 14 to 18 years; mean HIV knowledge scores ranged from 11.4 to 14.1 (maximum score = 18). Males had significantly lower HIV knowledge scores than females at baseline only. Over time, Hispanic participants had significantly lower scores than non-Hispanic Black and non-Hispanic White participants. Overall, HIV knowledge increased but was still suboptimal 5 years after baseline. These findings suggest the need to develop and strengthen HIV prevention education programs in youth detention settings., (© The Author(s) 2015.)

Objective: To examine the relationship between psychiatric disorders and violence in delinquent youth after detention., Method: The Northwestern Juvenile Project is a longitudinal study of youth from the Cook County Juvenile Temporary Detention Center (Chicago, Illinois). Violence and psychiatric disorders were assessed via self-report in 1,659 youth (56% African American, 28% Hispanic, 36% female, aged 13-25 years) interviewed up to 4 times between 3 and 5 years after detention. Using generalized estimating equations and logistic regression, we examined the following: the prevalence of violence 3 and 5 years after detention; the contemporaneous relationships between psychiatric disorders and violence as youth age; and whether the presence of a psychiatric disorder predicts subsequent violence., Results: Rates of any violence decreased between 3 and 5 years after detention, from 35% to 21% (males), and from 20% to 17% (females). There was a contemporaneous relationship between disorder and violence. Compared to the group with no disorder, males and females with any disorder had greater odds of any violence (adjusted odds ratio [AOR] = 3.0, 95% CI = 1.9-4.7, and AOR = 4.4, 95% CI = 3.0-6.3, respectively). All specific disorders were associated contemporaneously with violence, except for major depressive disorder/dysthymia among males. Substance use disorders predicted subsequent violence. Males with other drug use disorder and females with marijuana use disorder 3 years after detention had greater odds of any violence 2 years later (AOR = 3.4, 95% CI = 1.4-8.2, and AOR = 2.0, 95% CI = 1.1-3.8, respectively)., Conclusion: Aside from substance use disorders, the psychiatric disorders studied may not be useful markers of subsequent violence. Violence assessment and reduction must be key components of ongoing psychiatric services for high-risk youth., (Copyright © 2015 American Academy of Child and Adolescent Psychiatry.

Introduction: Statistics is an essential training component for a career in clinical and translational science (CTS). Given the increasing complexity of statistics, learners may have difficulty selecting appropriate courses. Our question was: what depth of statistical knowledge do different CTS learners require?, Methods: For three types of CTS learners (principal investigator, co-investigator, informed reader of the literature), each with different backgrounds in research (no previous research experience, reader of the research literature, previous research experience), 18 experts in biostatistics, epidemiology, and research design proposed levels for 21 statistical competencies., Results: Statistical competencies were categorized as fundamental, intermediate, or specialized. CTS learners who intend to become independent principal investigators require more specialized training, while those intending to become informed consumers of the medical literature require more fundamental education. For most competencies, less training was proposed for those with more research background., Discussion: When selecting statistical coursework, the learner's research background and career goal should guide the decision. Some statistical competencies are considered to be more important than others. Baseline knowledge assessments may help learners identify appropriate coursework., Conclusion: Rather than one size fits all, tailoring education to baseline knowledge, learner background, and future goals increases learning potential while minimizing classroom time., (© 2014 Wiley Periodicals, Inc.)

Importance: Psychiatric disorders and comorbidity are prevalent among incarcerated juveniles. To date, no large-scale study has examined the comorbidity and continuity of psychiatric disorders after youth leave detention., Objective: To determine the comorbidity and continuity of psychiatric disorders among youth 5 years after detention., Design, Setting, and Participants: Prospective longitudinal study of a stratified random sample of 1829 youth (1172 male and 657 female; 1005 African American, 296 non-Hispanic white, 524 Hispanic, and 4 other race/ethnicity) recruited from the Cook County Juvenile Temporary Detention Center, Chicago, Illinois, between November 20, 1995, and June 14, 1998, and who received their time 2 follow-up interview between May 22, 2000, and April 3, 2004., Main Outcomes and Measures: At baseline, the Diagnostic Interview Schedule for Children Version 2.3. At follow-ups, the Diagnostic Interview Schedule for Children Version IV (child and young adult versions) and the Diagnostic Interview Schedule Version IV (substance use disorders and antisocial personality disorder)., Results: Five years after detention, when participants were 14 to 24 years old, almost 27% of males and 14% of females had comorbid psychiatric disorders. Although females had significantly higher rates of comorbidity when in detention (odds ratio, 1.3; 95% CI, 1.0-1.7), males had significantly higher rates than females at follow-up (odds ratio, 2.3; 95% CI, 1.6-3.3). Substance use plus behavioral disorders was the most common comorbid profile among males, affecting 1 in 6. Participants with more disorders at baseline were more likely to have a disorder approximately 5 years after detention, even after adjusting for demographic characteristics. We found substantial continuity of disorder. However, some baseline disorders predicted alcohol and drug use disorders at follow-up., Conclusions and Relevance: Although prevalence rates of comorbidity decreased in youth after detention, rates remained substantial and were higher than rates in the most comparable studies of the general population. Youth with multiple disorders at baseline are at highest risk for disorder 5 years later. Because many psychiatric disorders first appear in childhood and adolescence, primary and secondary prevention of psychiatric disorders offers the greatest opportunity to reduce costs to individuals, families, and society. Only a concerted effort to address the many needs of delinquent youth will help them thrive in adulthood.

Background: Delinquent youth are at risk for early violent death after release from detention. However, few studies have examined risk factors for mortality. Previous investigations studied only serious offenders (a fraction of the juvenile justice population) and provided little data on females., Methods: The Northwestern Juvenile Project is a prospective longitudinal study of health needs and outcomes of a stratified random sample of 1829 youth (657 females, 1172 males; 524 Hispanic, 1005 African American, 296 non-Hispanic white, 4 other race/ethnicity) detained between 1995 and 1998. Data on risk factors were drawn from interviews; death records were obtained up to 16 years after detention. We compared all-cause mortality rates and causes of death with those of the general population. Survival analyses were used to examine risk factors for mortality after youth leave detention., Results: Delinquent youth have higher mortality rates than the general population to age 29 years (P < .05), irrespective of gender or race/ethnicity. Females died at nearly 5 times the general population rate (P < .05); Hispanic males and females died at 5 and 9 times the general population rates, respectively (P < .05). Compared with the general population, significantly more delinquent youth died of homicide and its subcategory, homicide by firearm (P < .05). Among delinquent youth, racial/ethnic minorities were at increased risk of homicide compared with non-Hispanic whites (P < .05). Significant risk factors for external-cause mortality and homicide included drug dealing (up to 9 years later), alcohol use disorder, and gang membership (up to a decade later)., Conclusions: Delinquent youth are an identifiable target population to reduce disparities in early violent death., (Copyright © 2014 by the American Academy of Pediatrics.)

Data analysis is essential to translational medicine, epidemiology, and the scientific process. Although recent advances in promoting reproducibility and reporting standards have made some improvements, the data analysis process remains insufficiently documented and susceptible to avoidable errors, bias, and even fraud. Comprehensively accounting for the full analytical process requires not only records of the statistical methodology used, but also records of communications among the research team. In this regard, the data analysis process can benefit from the principle of accountability that is inherent in other disciplines such as clinical practice. We propose a novel framework for capturing the analytical narrative called the Accountable Data Analysis Process (ADAP), which allows the entire research team to participate in the analysis in a supervised and transparent way. The framework is analogous to an electronic health record in which the dataset is the "patient" and actions related to the dataset are recorded in a project management system. We discuss the design, advantages, and challenges in implementing this type of system in the context of academic health centers, where team based science increasingly demands accountability.

Cognitive functioning affects health. This study assessed cognitive functioning among participants in the Northwestern Juvenile Project, a stratified random sample of 1,829 newly detained juveniles (10 to 18 years old) from Cook County, Illinois. The study examined receptive vocabulary, oral reading, arithmetic computation skills, and general intellectual abilities. The sample exhibited impaired overall intellectual functioning and deficits in all areas. Males performed more poorly than females. More than three quarters of males showed below average overall intellectual functioning, and 9 in 10 had below average receptive vocabulary skills. Hispanic and African American males performed more poorly than non-Hispanic White males. The multiple systems that serve delinquent youth--correctional, health, legal, and rehabilitative--must collaborate to tailor needed services to the cognitive level of youth in the juvenile justice system.

Biostatistics--the application of statistics to understanding health and biology-provides powerful tools for developing research questions, designing studies, refining measurements, analyzing data, and interpreting findings. Biostatistics plays an important role in health-related research, yet biostatistics resources are often fragmented, ad hoc, or oversubscribed within academic health centers (AHCs). Given the increasing complexity and quantity of health-related data, the emphasis on accelerating clinical and translational science, and the importance of conducting reproducible research, the need for the thoughtful development of biostatistics resources within AHCs is growing.In this article, the authors identify strategies for developing biostatistics resources in three areas: (1) recruiting and retaining biostatisticians, (2) efficiently using biostatistics resources, and (3) improving biostatistical contributions to science. AHCs should consider these three domains in building strong biostatistics resources, which they can leverage to support a broad spectrum of research. For each of the three domains, the authors describe the advantages and disadvantages of AHCs creating centralized biostatistics units rather than dispersing such resources across clinical departments or other research units. They also address the challenges that biostatisticians face in contributing to research without sacrificing their individual professional growth or the trajectory of their research teams. The authors ultimately recommend that AHCs create centralized biostatistics units because this approach offers distinct advantages both to investigators who collaborate with biostatisticians as well as to the biostatisticians themselves, and it is better suited to accomplish the research and education missions of AHCs.

Objective: This study examined the prevalence of childhood maltreatment and its relationship with current psychiatric disorders among detained youths., Methods: Clinical research interviewers assessed history of childhood maltreatment with the Child Maltreatment Assessment Profile and psychiatric diagnosis with the Diagnostic Interview Schedule for Children, version 2.3, in a stratified, random sample of 1,829 youths detained at the Cook Country Juvenile Temporary Detention Center (final sample, N=1,735). History of maltreatment was also ascertained from Cook County Court Child Protection Division records., Results: More than three-quarters of females and more than two-thirds of males had a history of physical abuse (moderate or severe). More than 40% of females and 10% of males had a history of sexual abuse. Females and non-Hispanic whites had the highest prevalence rates of childhood maltreatment. Among females, sexual abuse was associated with every type of psychiatric disorder. Females who experienced various types of abuse were 2.6 to 10.7 times as likely as females with no maltreatment to have any disorder. Among males, maltreatment was associated with every disorder except anxiety disorders (range of odds ratios, 1.9-7.9). Among youths who were sexually abused, abuse with force was associated with anxiety and affective disorders among females and attention-deficit hyperactivity or disruptive behavior disorders and substance use disorders among males., Conclusions: Childhood maltreatment is common among detained youths and is also highly associated with psychiatric disorders. The mental health, child welfare, and juvenile justice systems must collaborate to ensure that youths receive protection and care when they return to their communities.

Increasing demands for evidence-based medicine and for the translation of biomedical research into individual and public health benefit have been accompanied by the proliferation of special units that offer expertise in biostatistics, epidemiology, and research design (BERD) within academic health centers. Objective metrics that can be used to evaluate, track, and improve the performance of these BERD units are critical to their successful establishment and sustainable future. To develop a set of reliable but versatile metrics that can be adapted easily to different environments and evolving needs, we consulted with members of BERD units from the consortium of academic health centers funded by the Clinical and Translational Science Award Program of the National Institutes of Health. Through a systematic process of consensus building and document drafting, we formulated metrics that covered the three identified domains of BERD practices: the development and maintenance of collaborations with clinical and translational science investigators, the application of BERD-related methods to clinical and translational research, and the discovery of novel BERD-related methodologies. In this article, we describe the set of metrics and advocate their use for evaluating BERD practices. The routine application, comparison of findings across diverse BERD units, and ongoing refinement of the metrics will identify trends, facilitate meaningful changes, and ultimately enhance the contribution of BERD activities to biomedical research., (Copyright © 2011 John Wiley & Sons, Ltd.)

Objective: To determine the efficacy of patient-selected treatment partners on virologic and adherence outcomes during first-line antiretroviral therapy., Design: Randomized controlled trial. SETTING AND ANALYTICAL APPROACH: Between June 2006 and December 2007, 499 HIV-infected adults in Jos, Nigeria, were randomized to standard of care (SOC) or patient-selected treatment partner-assisted therapy (TPA). Each patient was followed for 48 weeks. Virologic outcomes, adherence to drug pick-up, CD4 cell counts, and mortality are reported., Results: At week 24, undetectable viral load was achieved by 61.7% of patients in the TPA arm versus 50.2% of those receiving SOC [odds ratio (OR) = 1.58, 95% CI: 1.11 to 2.26, P < 0.05]. There was no significant difference at week 48: 65.3% versus 59.4% for TPA and SOC, respectively (OR = 1.28, 95% CI: 0.89 to 1.84, P > 0.05). The TPA group had more than 3 times the odds of at least 95% drug pickup adherence through week 24 (OR = 3.06, 95% CI: 1.89 to 4.94, P < 0.01) and almost twice the odds through week 48 (OR = 1.95, 95% CI: 1.29 to 2.93, P < 0.01). At week 48, there were no significant differences in CD4 cell count increases (t = -0.09, df = 404, P > 0.05) or mortality (10.6% vs. 6.1%) between TPA vs. SOC, respectively. Residence-to-clinic distance was significantly associated with virologic and adherence outcomes., Conclusions: Use of patient-selected treatment partners was associated with improved drug pickup adherence and initial virologic success but had no durable effect on attaining undetectable viral load.

A distributed lag model (DLagM) is a regression model that includes lagged exposure variables as covariates; its corresponding distributed lag (DL) function describes the relationship between the lag and the coefficient of the lagged exposure variable. DLagMs have recently been used in environmental epidemiology for quantifying the cumulative effects of weather and air pollution on mortality and morbidity. Standard methods for formulating DLagMs include unconstrained, polynomial, and penalized spline DLagMs. These methods may fail to take full advantage of prior information about the shape of the DL function for environmental exposures, or for any other exposure with effects that are believed to smoothly approach zero as lag increases, and are therefore at risk of producing suboptimal estimates. In this article, we propose a Bayesian DLagM (BDLagM) that incorporates prior knowledge about the shape of the DL function and also allows the degree of smoothness of the DL function to be estimated from the data. We apply our BDLagM to its motivating data from the National Morbidity, Mortality, and Air Pollution Study to estimate the short-term health effects of particulate matter air pollution on mortality from 1987 to 2000 for Chicago, Illinois. In a simulation study, we compare our Bayesian approach with alternative methods that use unconstrained, polynomial, and penalized spline DLagMs. We also illustrate the connection between BDLagMs and penalized spline DLagMs. Software for fitting BDLagM models and the data used in this article are available online.

Objectives: To examine the prevalence and persistence of 20 human immunodeficiency virus (HIV)/sexually transmitted infection (STI) sexual and drug use risk behaviors and to predict their occurrence in four mutually exclusive diagnostic groups of delinquent youths: major mental disorder (MMD), substance use disorder (SUD), comorbid MMD and SUD (MMD+SUD), and neither disorder., Method: At the baseline interview, HIV/STI risk behaviors were assessed in 800 juvenile detainees, ages 10 to 18 years; youths were reinterviewed approximately 3 years later. The final sample (N = 689) includes 298 females and 391 males., Results: The prevalence and persistence of HIV/STI risk behaviors were high in all of the diagnostic groups. Youths with an SUD at baseline were greater than 10 times more likely to be sexually active and to have vaginal sex at follow-up than youths with MMD+SUD (adjusted odds ratio [AOR] 10.86, 95% confidence interval [CI] 1.43-82.32; AOR 11.63, 95% CI 1.49-90.89, respectively) and four times more likely to be sexually active and to have vaginal sex than youths with neither disorder (AOR 4.20, 95% CI 1.06-16.62; AOR 4.73, 95% CI 1.21-18.50, respectively). Youths with an MMD at baseline were less likely to have engaged in unprotected vaginal and oral sex at follow-up compared with youths with neither disorder (AOR0.11, 95% CI 0.02-0.50; AOR 0.07, 95% CI 0.01-0.34, respectively), and with youths with an SUD (AOR 0.10, 95% CI 0.02-0.50; AOR 0.10, 95% CI 0.02-0.47, respectively). Youths with MMD+SUD were less likely (AOR 0.28, 95% CI 0.09-0.92) to engage in unprotected oral sex compared with those with neither disorder., Conclusions: Irrespective of diagnostic group, delinquent youths are at great risk for HIV/STIs as they enter into adulthood. SUD increases risk. Because detained youths are released after approximately 2 weeks, their risk behaviors become a community health problem. Pediatricians and child and adolescent psychiatrists must collaborate with corrections professionals to develop HIV/STI interventions and ensure that programs started in detention centers continue after youths are released.

Although trihexyphenidyl is used clinically to treat both primary and secondary dystonia in children, limited evidence exists to support its effectiveness, particularly in dystonia secondary to disorders such as cerebral palsy. A prospective, open-label, multicenter pilot trial of high-dose trihexyphenidyl was conducted in 23 children aged 4 to 15 years with cerebral palsy judged to have secondary dystonia impairing function in the dominant upper extremity. All children were given trihexyphenidyl at increasing doses over a 9-week period up to a maximum of 0.75 mg/kg/d. Trihexyphenidyl was subsequently tapered off over the next 5 weeks. Objective motor assessments were performed at baseline, 9 weeks, and 15 weeks. The primary outcome measure was the Melbourne Assessment of Unilateral Upper Limb Function, tested in the dominant arm. Tolerability and safety were monitored closely throughout the trial. Of the 31 children who agreed to participate in the study, 5 failed to meet entry criteria and 3 withdrew due to nonserious adverse events (chorea, drug rash, and hyperactivity). Three children required a dosage reduction because of nonserious adverse events but continued to participate. The 23 children who completed the study showed a significant improvement in arm function at 15 weeks (P = .045) but not at 9 weeks (P = .985). Post hoc analysis showed that a subgroup (n = 10) with hyperkinetic dystonia (excess involuntary movements) worsened at 9 weeks (P = .04) but subsequently returned to baseline following taper of the medicine. The authors conclude that scientific evidence for the clinical use of trihexyphenidyl in cerebral palsy remains equivocal. Trihexyphenidyl may be a safe and effective for treatment for arm dystonia in some children with cerebral palsy if given sufficient time to respond to the medication. Post hoc analyses based on the type of movement disorder suggested that children with hyperkinetic forms of dystonia may worsen. A larger, randomized prospective trial stratified by the presence or absence of hyperkinetic movements is needed to confirm these results.

Antisocial personality disorder (APD) is a serious public and mental health concern. Understanding how well conduct disorder (CD) and other mental disorders predict the development of APD among youths involved in the juvenile justice system is critical for prevention. The authors used a stratified random sample of 1,112 detained youths to examine the development of APD at a 3-year follow-up interview. Nearly one fifth of male juvenile detainees later developed APD; approximately one quarter of male juvenile detainees with CD at baseline later developed APD. Significantly more males than females developed APD; no differences were found by race/ethnicity. Having 5 or more symptoms of CD, dysthymia, alcohol use disorder, or generalized anxiety disorder was significantly associated with developing modified APD (M-APD; APD without the CD requirement). Some disorders were strong predictors of APD; however, none were adequate screeners for identifying which detainees would later develop M-APD. The findings of this study have implications for interventions and further research in developmental psychopathology., (Copyright 2007 APA, all rights reserved.)

Time-series studies have linked daily variations in nonaccidental deaths with daily variations in ambient particulate matter air pollution, while controlling for qualitatively larger influences of weather and season. Although time-series analyses typically include nonlinear terms for weather and season, questions remain as to whether models to date have completely controlled for these important predictors. In this paper, the authors use two flexible versions of distributed lag models to control extensively for the confounding effects of weather and season. One version builds on the current approach to controlling for weather, while the other version offers a new approach. The authors conduct a comprehensive sensitivity analysis of the particulate matter-mortality relation by applying these methods to the recently updated National Morbidity, Mortality, and Air Pollution Study database that comprises air pollution, weather, and mortality time series from 1987 to 2000 for 100 US cities. They combine city-specific estimates of the short-term effects of particulate matter on mortality using a Bayesian hierarchical model. They conclude that, within the broad classes of models considered, national average estimates of particulate matter relative risk are consistent with previous estimates from this study and are robust to model specification for weather and seasonal confounding.
