Stability of the Motor Optimality Score Revised (MOS-R) in medically complex infants.

BACKGROUND: The Motor Optimality Score-Revised (MOS-R) is a clinical test of infant spontaneous movement at 3-5 months of age and has been associated with neurodevelopmental outcomes in infants with medical complexity. However the stability of the MOS-R tested at different developmental ages is not yet known. AIM: To determine if the repeated scoring of the MOS-R remained consistent when tested at two developmental ages in young infants. STUDY DESIGN: In this prospective cohort study, infants were tested twice with the MOS-R between 12 and 13 weeks corrected age (CA) and 14-16 weeks CA. Bland Altman Plots were used to calculate agreement between the scores. Infants were grouped as having higher or lower medical complexity. MOS-R threshold scores were analyzed to assess changes over time within each group using Fisher's exact test. SUBJECTS: 85 infants with history of hospitalization in a neonatal intensive care unit (NICU). RESULTS: The MOS-R scores had a high agreement with negligible bias (0.058) between timepoints (95 % CI -1.10, 1.22). Using a MOS-R cut point of 19, infants with higher medical complexity were more likely to change groups between timepoints than infants with lower medical complexity (p = 0.008), but this was not significantly different using cut points of 20 or 21. CONCLUSION: The MOS-R scores were stable when measured repeatedly in infants who were hospitalized in a NICU. Infants with high medical complexity had less stable MOS-R scores using certain cut points than infants with lower medical complexity.

Implementation of perinatal quality collaborative statewide initiative improves obstetrical opioid use disorder care and outcomes.

BACKGROUND: Maternal deaths resulting from opioid use disorder have been increasing across the United States. Opioid use disorder among pregnant persons is associated with adverse pregnancy outcomes, including preterm birth, along with racial disparities in optimal opioid use disorder care. OBJECTIVE: This study aimed to evaluate whether the Illinois Perinatal Quality Collaborative implementation of the Mothers and Newborns affected by Opioids - Obstetric quality improvement initiative was associated with improvement in opioid use disorder identification, provision of optimal opioid use disorder care for birthing patients, and reduction in racial gaps in optimal opioid use disorder care. STUDY DESIGN: Using a prospective cohort design, hospitals reported monthly key measures for all patients with opioid use disorder at delivery between July 2018 and December 2020. The Illinois Perinatal Quality Collaborative facilitates collaborative learning opportunities, rapid response data, and quality improvement support. Generalized linear mixed-effects regression models were used to evaluate improvement in optimal opioid use disorder care, including increases in linkages to medication-assisted treatment, recovery treatment services, and naloxone counseling across time, and to determine whether optimal opioid use disorder care was associated with positive outcomes, such as lower odds of preterm birth. RESULTS: A total of 91 hospitals submitted data on 2095 pregnant persons with opioid use disorder. For the primary outcomes, the rates of patients receiving medication-assisted treatment and recovery treatment services improved across the initiative from 41% to 78% and 48% to 67%, respectively. For the secondary outcomes, the receipt of recovery treatment services and both recovery treatment services and medication-assisted treatment provided prenatally before delivery admission was associated with lower odds of preterm birth (adjusted odds ratio: 0.67 [95% confidence interval, 0.50-0.91] and 0.49 [95% confidence interval, 0.31-0.75], respectively). During the first quarter of the initiative, Black patients with opioid use disorder were less likely to be linked to medication-assisted treatment than White patients (23% vs 48%, respectively); however, an increase in medication-assisted treatment rates across the initiative occurred for all patients, with the greatest improvement for Black patients with an associated reduction in this disparity gap with >70% of both Black and White patients linked to medication-assisted treatment. CONCLUSION: The Mothers and Newborns affected by Opioids - Obstetric initiative was associated with improvement in optimal opioid use disorder care for pregnant patients across Illinois hospitals, additionally racial disparities in opioid use disorder care was reduced across the initiative. Our findings implicate how optimal opioid use disorder care can improve pregnancy outcomes and close persistent racial gaps for pregnant individuals with opioid use disorder.

Baby Observational Selective Control AppRaisal (BabyOSCAR): Scores at 3 months predict functional ability, spastic cerebral palsy distribution, and diagnosis at 2 years.

AIM: To assess the predictive capabilities of the Baby Observational Selective Control AppRaisal (BabyOSCAR) tool, administered at 3 months corrected age, in determining spastic cerebral palsy (CP) outcome, functional abilities, and body topography at 2 years of age or later. METHOD: Independent joint motions were measured at age 10 to 16 weeks from video recordings of spontaneous movement using BabyOSCAR in a sample of 75 infants. All included infants had known 2-year outcomes (45 with spastic CP and 30 without CP) including Gross Motor Functional Classification System (GMFCS) levels and CP body distribution. Receiver operating characteristic curves and cut points indicating greatest sensitivity and specificity were generated for predictive performance. RESULTS: Total BabyOSCAR score was a strong predictor of future outcome of spastic CP (cut score of 22.5, sensitivity = 98%, specificity = 100%, area under the curve = 0.99), and was able to distinguish children classified in GMFCS levels I and II from those in III to V (cut score of 13.5, sensitivity = 92%, specificity = 89%, area under the curve = 0.94). Having an (absolute) asymmetry score on the BabyOSCAR of more than 5 was a predictor of having unilateral CP at age 2 years (sensitivity = 56%, specificity = 100%, area under the curve = 0.86). INTERPRETATION: BabyOSCAR scores are predictors of diagnosis, body distribution, and future gross motor function in infants with spastic CP at 2 years of age or later.

Assessing Neonatal Intensive Care Unit (NICU) Graduates Across Varied Settings: A Study on the Feasibility of the Baby Moves App.

We assessed the feasibility of obtaining parent-collected General Movement Assessment videos using the Baby Moves app. Among 261 participants from 4 Chicago NICUs, 70% submitted videos. Families living in higher areas of childhood opportunity used the app more than those from areas of lower opportunity.

Gender differences in the relationship between sleep and age in a Brazilian cohort: the Baependi Heart Study.

Gender and age are well-established determinants of health and sleep health that influence overall health, which also often varies by gender and age. Sleep architecture is an important component of sleep health. The goal of this analysis was to examine whether associations between age and sleep stages differ by gender in the absence of moderate-severe obstructive sleep apnea (OSA) in a rural setting in Brazil. This study conducted polysomnography recordings in the Baependi Heart Study, a cohort of Brazilian adults. Our sample included 584 women and 309 men whose apnea-hypopnea index was ≤15 events/h. We used splines to distinguish non-linear associations between age, total sleep time, wake after sleep onset (WASO), N2, N3, and rapid-eye-movement sleep. The mean (standard deviation; range) age was 47 (14; 18-89) years. All sleep outcomes were associated with age. Compared to men, women had more N3 sleep and less WASO after adjusting for age. Model-based comparisons between genders at specific ages showed statistically higher mean WASO for men at ages 60 (+13.6 min) and 70 years (+19.5 min) and less N3 for men at ages 50 (-13.2 min), 60 (-19.0 min), and 70 years (-19.5 min) but no differences at 20, 30, 40 or 80 years. The other sleep measures did not differ by gender at any age. Thus, even in the absence of moderate-severe OSA, sleep architecture was associated with age across adulthood, and there were gender differences in WASO and N3 at older ages in this rural community.

Inequities in Mental Health Services: A 16-Year Longitudinal Study of Youth in the Justice System.

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.

Altered sleep architecture in diabetes and prediabetes: findings from the Baependi Heart Study.

STUDY OBJECTIVES: People with diabetes and prediabetes are more likely to have sleep-disordered breathing (SDB), but few studies examined sleep architecture in people with diabetes or prediabetes in the absence of moderate-severe SDB, which was the aim of our cross-sectional study. METHODS: This cross-sectional sample is from the Baependi Heart Study, a family-based cohort of adults in Brazil. About 1074 participants underwent at-home polysomnography (PSG). Diabetes was defined as fasting glucose >125 mg/dL or HbA1c > 6.4 mmol/mol or taking diabetic medication, and prediabetes was defined as HbA1c ≥ 5.7 & <6.5 mmol/mol or fasting glucose ≥ 100 & ≤125 mg/dl. We excluded participants with an apnea-hypopnea index (AHI) ≥ 30 in primary analyses and ≥ 15 in secondary analysis. We compared sleep stages among the 3 diabetes groups (prediabetes, diabetes, neither). RESULTS: Compared to those without diabetes, we found shorter REM duration for participants with diabetes (-6.7 min, 95%CI -13.2, -0.1) and prediabetes (-5.9 min, 95%CI -10.5, -1.3), even after adjusting for age, gender, BMI, and AHI. Diabetes was also associated with lower total sleep time (-13.7 min, 95%CI -26.8, -0.6), longer slow-wave sleep (N3) duration (+7.6 min, 95%CI 0.6, 14.6) and higher N3 percentage (+2.4%, 95%CI 0.6, 4.2), compared to those without diabetes. Results were similar when restricting to AHI < 15. CONCLUSIONS: People with diabetes and prediabetes had less REM sleep than people without either condition. People with diabetes also had more N3 sleep. These results suggest that diabetes and prediabetes are associated with differences in sleep architecture, even in the absence of moderate-severe sleep apnea.

Antimüllerian hormone level predicts ovulation in women with polycystic ovary syndrome treated with clomiphene and metformin.

OBJECTIVE: To describe the serum anti-Müllerian hormone (AMH) concentrations in a large, well-phenotyped cohort of women with polycystic ovary syndrome (PCOS) and evaluate whether AMH predicts successful ovulation induction in women treated with clomiphene and metformin. DESIGN: Secondary analysis of randomized controlled trial. SETTING: Not applicable. PATIENT(S): A total of 333 women with anovulatory infertility attributed to PCOS who participated in the double-blind randomized trial entitled the Pregnancy in Polycystic Ovary Syndrome I (PPCOS I) study (registration number, NCT00068861) who had serum samples from baseline laboratory testing available for further serum analysis were studied. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): The association between the baseline AMH levels in each of the 3 treatment groups and ovulation, pregnancy, and live birth rates were assessed. RESULT(S): A total of 322 individuals had a baseline AMH concentration available, of which the mean AMH was 11.7 ± 8.3 ng/mL (range 0.1-43.0 ng/mL). With each unit (1 ng/mL) increase in baseline AMH, the odds of ovulation decreased by 10% (odds ratio, 0.90; 95% confidence interval, 0.86-0.93); this effect did not differ by treatment group. Women with a high baseline AMH concentration (>8 ng/mL) were significantly less likely to ovulate compared with those with a normal baseline AMH concentration (<4 ng/mL) (odds ratio, 0.23; 95% confidence interval, 0.05-0.68). This remained statistically significant when controlling for confounders, including age, body mass index, time in study, and Homeostatic Model Assessment for Insulin Resistance score. Ovulation occurred even at very high AMH concentrations; there was no maximum level noted at which no ovulation events occurred. Baseline AMH concentration was not associated with pregnancy or live birth rates when controlling for confounders. CONCLUSION(S): These AMH values in well-phenotyped individuals with PCOS add to the literature and will aid in identifying AMH criteria for the diagnosis of PCOS. In women with infertility and PCOS, a higher AMH concentration was associated with reduced odds of ovulation with ovulation induction with clomiphene, clomiphene + metformin, and metformin. CLINICAL TRIAL REGISTRATION NUMBER: The original trial from which this analysis is derived was entitled "Pregnancy in Polycystic Ovary Syndrome: A 30 Week Double-Blind Randomized Trial of Clomiphene Citrate, Metformin XR, and Combined Clomiphene Citrate/Metformin XR For the Treatment of Infertility in Women With Polycystic Ovary Syndrome" and was registered on ClinicalTrials.gov as number NCT00068861. The URL for the trial is https://clinicaltrials.gov/study/NCT00068861. The first subject was enrolled in November 2002.

White matter tracts contribute selectively to cognitive functioning in patients with glioma.

Objective: The functional organization of white matter (WM) tracts is not well characterized, especially in patients with intrinsic brain tumors where complex patterns of tissue injury, compression, and neuroplasticity may be present. This study uses diffusion tensor imaging (DTI) to investigate the relationships between WM tract disruption and cognitive deficits in glioma patients. Methods: Seventy-nine patients with glioma underwent preoperative DTI and neuropsychological testing. Thirteen WM tracts were reconstructed bilaterally. Fractional anisotropy and streamline number were obtained for each tract as indices of connectivity. Univariate regression models were used to model the association between WM tract connectivity and neuropsychological outcomes. Results: Glioma patients exhibited variable injury to WM tracts and variable cognitive deficits on validated neuropsychological tests. We identified 16 age-adjusted associations between WM tract integrity and neuropsychological function. The left inferior frontal-occipital fasciculus (IFOF) predicted list learning and dominant-hand fine motor dexterity. The right IFOF predicted non-dominant-hand fine motor dexterity and visuospatial index scores. The left inferior longitudinal fasciculus (ILF) predicted immediate memory list learning and index scores. The right ILF predicted non-dominant-hand fine motor dexterity and backward digit span scores. The left superior longitudinal fasciculus (SLF) I predicted processing speed. The left SLF III predicted list learning, immediate memory index scores, phonemic fluency, and verbal abstract reasoning. The left cingulum predicted processing speed. The right anterior AF predicted verbal abstract reasoning. Conclusion: WM tract disruption predicts cognitive dysfunction in glioma patients. By improving knowledge of WM tract organization, this analysis may guide maximum surgical resection and functional preservation in glioma patients.

Substance Use Disorders and HIV/AIDS Risk Behaviors in Youth After Juvenile Detention: A 16-Year Longitudinal Study.

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.

Nonfatal Firearm Injury and Firearm Mortality in High-risk Youths and Young Adults 25 Years After Detention.

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.

Altered sleep architecture in diabetes and prediabetes: findings from the Baependi Heart Study.

Objective: People with diabetes are more likely to have obstructive sleep apnea, but there are few studies examining sleep architecture in people with diabetes, especially in the absence of moderate-severe sleep apnea. Therefore, we compared sleep architecture among people with diabetes, prediabetes or neither condition, whilst excluding people with moderate-severe sleep apnea. Research design and methods: This sample is from the Baependi Heart Study, a prospective, family-based cohort of adults in Brazil. 1,074 participants underwent at-home polysomnography (PSG). Diabetes was defined as 1) FBG>125 OR 2) HbA1c>6.4 OR 3) taking diabetic medication, and prediabetes was defined as 1) [(5.7≤HbA1c≤6.4) OR (100≤FBG≤125)] AND 2) not taking diabetic medication. We excluded participants that had an apnea-hypopnea index (AHI)>30 from these analyses to reduce confounding due to severe sleep apnea. We compared sleep stages among the 3 groups. Results: Compared to those without diabetes, we found shorter REM duration for participants with diabetes (-6.7min, 95%CI -13.2, -0.1) or prediabetes (-5.9min, 95%CI -10.5, -1.3), even after adjusting for age, gender, BMI, and AHI. Diabetes was also associated with lower total sleep time (-13.7min, 95%CI -26.8, -0.6), longer slow-wave sleep (N3) duration (+7.6min, 95%CI 0.6, 14.6) and higher N3 percentage (+2.4%, 95%CI 0.6, 4.2), compared to those without diabetes. Conclusions: People with diabetes and prediabetes had less REM sleep after taking into account potential confounders, including AHI. People with diabetes also had more N3 sleep. These results suggest that diabetes is associated with different sleep architecture, even in the absence of moderate-severe sleep apnea.

Development of a Remote Version of the Graded Redefined Assessment of Strength, Sensation, and Prehension (GRASSP): Validity and Reliability.

BACKGROUND: The Graded Redefined Assessment of Strength, Sensation, and Prehension (GRASSP V1.0) was developed in 2010 as a 3-domain assessment for upper extremity function after tetraplegia (domains: Strength, Sensibility, and Prehension). A remote version (rGRASSP) was created in response to the growing needs of the field of Telemedicine. OBJECTIVE: The purpose of this study was to assess the psychometric properties of rGRASSP, establishing concurrent validity and inter-rater reliability. METHODS: Individuals with tetraplegia (n = 61) completed 2 visits: 1 in-person and 1 remote. The first visit was completed in-person to administer the GRASSP, and the second visit was conducted remotely to administer the rGRASSP. The rGRASSP was scored both by the administrator of the rGRASSP (Examiner 1), and a second assessor (Examiner 2) to establish inter-rater reliability. Agreement between the in-person and remote GRASSP evaluations was assessed using the intraclass correlation coefficient (ICC) and Bland-Altman agreement plots. RESULTS: The remote GRASSP demonstrated excellent concurrent validity with the GRASSP (left hand intraclass correlation coefficient (ICC) = .96, right ICC = .96). Concurrent validity for the domains was excellent for strength (left ICC = .96, right ICC = .95), prehension ability (left ICC = .94, right ICC = .95), and prehension performance (left ICC = .92, right ICC = .93), and moderate for sensibility (left ICC = .59, right ICC = .68). Inter-rater reliability for rGRASSP total score was high (ICC = .99), and remained high for all 4 domains. Bland-Altman plots and limits of agreements support these findings. CONCLUSIONS: The rGRASSP shows strong concurrent validity and inter-rater reliability, providing a psychometrically sound remote assessment for the upper extremity in individuals with tetraplegia.

Body Image and Sexual Function Improve after Both Myomectomy and Hysterectomy for Symptomatic Fibroids.

OBJECTIVES: To determine the factors that influence the choice of myomectomy, uterine fibroid embolization (UFE), or hysterectomy in women with symptomatic uterine fibroids and to assess women's perception of body image and sexual functioning before and after treatment. METHODS: In this prospective observational cohort pilot study, women scheduled to undergo hysterectomy, myomectomy, or UFE were surveyed before surgery and again at 3 to 6 months after their procedure to assess body image and sexual function using the validated 10-item Body Image Scale and 19-item Female Sexual Function Index. Logistic regression was used to determine predictive factors for surgery choice and paired t tests were used to determine changes in perceived sexual function and body image. RESULTS: Of the 71 women surveyed, 69 underwent their scheduled procedure and 68 participants completed the preoperative questionnaire completely (98%). A total of 33 participants completed the postoperative questionnaire (49%). The predictive factor for hysterectomy versus myomectomy/UFE was older age (odds ratio 1.13, P = 0.017, 95% confidence interval [CI] 1.02-1.24). Regardless of surgery type, there were significant improvements in perceived body image and sexual function, including an increase in the overall sexual satisfaction of the participant (mean difference 0.50, P = 0.021, 95% CI 0.92-0.08) and less likely to feel less sexually attractive because of their menstrual bleeding problem (P < 0.0001, 95% CI 0.637-1.675). CONCLUSIONS: Women of older age are more likely to choose hysterectomy over myomectomy or UFE for the treatment of symptomatic uterine fibroids. In addition, women who underwent any treatment for fibroids have increases in perception of body image and sexual functioning after their procedure.

Effects of differential measurement error in self-reported diet in longitudinal lifestyle intervention studies.

BACKGROUND: Lifestyle intervention studies often use self-reported measures of diet as an outcome variable to measure changes in dietary intake. The presence of measurement error in self-reported diet due to participant failure to accurately report their diet is well known. Less familiar to researchers is differential measurement error, where the nature of measurement error differs by treatment group and/or time. Differential measurement error is often present in intervention studies and can result in biased estimates of the treatment effect and reduced power to detect treatment effects. Investigators need to be aware of the impact of differential measurement error when designing intervention studies that use self-reported measures. METHODS: We use simulation to assess the consequences of differential measurement error on the ability to estimate treatment effects in a two-arm randomized trial with two time points. We simulate data under a variety of scenarios, focusing on how different factors affect power to detect a treatment effect, bias of the treatment effect, and coverage of the 95% confidence interval of the treatment effect. Simulations use realistic scenarios based on data from the Trials of Hypertension Prevention Study. Simulated sample sizes ranged from 110-380 per group. RESULTS: Realistic differential measurement error seen in lifestyle intervention studies can require an increased sample size to achieve 80% power to detect a treatment effect and may result in a biased estimate of the treatment effect. CONCLUSIONS: Investigators designing intervention studies that use self-reported measures should take differential measurement error into account by increasing their sample size, incorporating an internal validation study, and/or identifying statistical methods to correct for differential measurement error.

Esophageal Dilation and Other Clinical Factors Associated With Pulmonary Function Decline in Patients With Systemic Sclerosis.

OBJECTIVE: To identify clinical factors, including esophageal dilation on chest high-resolution computed tomography (HRCT), that are associated with pulmonary function decline in patients with systemic sclerosis (SSc). METHODS: Patients fulfilled 2013 SSc criteria and had ≥ 1 HRCT and ≥ 2 pulmonary function tests (PFTs). According to published methods, widest esophageal diameter (WED) and radiographic interstitial lung disease (ILD) were assessed, and WED was dichotomized as dilated (≥ 19 mm) vs not dilated (< 19 mm). Clinically meaningful PFT decline was defined as % predicted change in forced vital capacity (FVC) ≥ 5 and/or diffusion capacity for carbon monoxide (DLCO) ≥ 15. Linear mixed effects models were used to model PFT change over time. RESULTS: One hundred thirty-eight patients with SSc met the study criteria: 100 (72%) had radiographic ILD; 49 (35%) demonstrated FVC decline (median follow-up 2.9 yrs). Patients with antitopoisomerase I (Scl-70) autoantibodies had 5-year FVC% predicted decline (-6.33, 95% CI -9.87 to -2.79), whereas patients without Scl-70 demonstrated 5-year FVC stability (+1.78, 95% CI -0.59 to 4.15). Esophageal diameter did not distinguish between those with vs without FVC decline. Patients with esophageal dilation had statistically significant 5-year DLCO% predicted decline (-5.58, 95% CI -10.00 to -1.15), but this decline was unlikely clinically significant. Similar results were observed in the subanalysis of patients with radiographic ILD. CONCLUSION: In patients with SSc, Scl-70 positivity is a risk factor for FVC% predicted decline at 5 years. Esophageal dilation on HRCT was associated with a minimal, nonclinically significant decline in DLCO and no change in FVC during the 5-year follow-up. These results have prognostic implications for SSc-ILD patients with esophageal dilation.

Prevalence, Comorbidity, and Continuity of Psychiatric Disorders in a 15-Year Longitudinal Study of Youths Involved in the Juvenile Justice System.

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.

Association of Firearm Access, Use, and Victimization During Adolescence With Firearm Perpetration During Adulthood in a 16-Year Longitudinal Study of Youth Involved in the Juvenile Justice System.

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.

eHealth Practices in Cancer Survivors With BMI in Overweight or Obese Categories: Latent Class Analysis Study.

BACKGROUND: eHealth technologies have been found to facilitate health-promoting practices among cancer survivors with BMI in overweight or obese categories; however, little is known about their engagement with eHealth to promote weight management and facilitate patient-clinician communication. OBJECTIVE: The objective of this study was to determine whether eHealth use was associated with sociodemographic characteristics, as well as medical history and experiences (ie, patient-related factors) among cancer survivors with BMI in overweight or obese categories. METHODS: Data were analyzed from a nationally representative cross-sectional survey (National Cancer Institute's Health Information National Trends Survey). Latent class analysis was used to derive distinct classes among cancer survivors based on sociodemographic characteristics, medical attributes, and medical experiences. Logistic regression was used to examine whether class membership was associated with different eHealth practices. RESULTS: Three distinct classes of cancer survivors with BMI in overweight or obese categories emerged: younger with no comorbidities, younger with comorbidities, and older with comorbidities. Compared to the other classes, the younger with comorbidities class had the highest probability of identifying as female (73%) and Hispanic (46%) and feeling that clinicians did not address their concerns (75%). The older with comorbidities class was 6.5 times more likely than the younger with comorbidities class to share eHealth data with a clinician (odds ratio [OR] 6.53, 95% CI 1.08-39.43). In contrast, the younger with no comorbidities class had a higher likelihood of using a computer to look for health information (OR 1.93, 95% CI 1.10-3.38), using an electronic device to track progress toward a health-related goal (OR 2.02, 95% CI 1.08-3.79), and using the internet to watch health-related YouTube videos (OR 2.70, 95% CI 1.52-4.81) than the older with comorbidities class. CONCLUSIONS: Class membership was associated with different patterns of eHealth engagement, indicating the importance of tailored digital strategies for delivering effective care. Future eHealth weight loss interventions should investigate strategies to engage younger cancer survivors with comorbidities and address racial and ethnic disparities in eHealth use.
