RESUMEN

Purpose: Schizophrenia is a severe, chronic condition accounting for disproportionate healthcare utilization. Antipsychotics can reduce relapse rates, but the characteristics of schizophrenia may hinder medication adherence. A phase 3b open-label clinical trial used aripiprazole tablets with sensor (AS; includes pills with ingestible event-marker, wearable sensor patches and smartphone application) in adults with schizophrenia. This post hoc analysis explored how healthcare providers' (HCPs) usage of a dashboard that provided medication ingestion information impacted treatment decisions and clinical assessments. Patients and Methods: Participants used AS for 3-6 months. HCPs were instructed to check the dashboard regularly, identify features used, and report impact on treatment decisions. After stratifying HCPs by frequency of dashboard checks and resulting treatment decisions, changes from baseline were calculated for Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression (CGI)-Severity of Illness and CGI-Improvement (CGI-I), and Personal and Social Performance (PSP), and compared using Mann-Whitney U-tests and rank-biserial correlation coefficient (r) effect sizes. Results: To ensure sufficient opportunity for AS engagement, 113 participants who completed ≥3 months on study were analyzed. HCPs most often accessed dashboard data regarding medication ingestion and missed doses. HCPs recommended adherence counseling and participant education most often. Participants whose HCPs used the dashboard more and recommended adherence counseling and participant education (n=61) improved significantly more than participants with less dashboard-active HCPs (n=49) in CGI-I mean score (2.9 versus 3.4 [p=0.004]), total PANSS (mean change: -9.2 versus -3.1 [p=0.0002]), PANSS positive subscale (-3.2 versus -1.5 [p=0.003]), PANSS general subscale (-4.3 versus -1.2 [p=0.02]), and Marder factor for negative symptoms (-1.9 versus 0.0 [p=0.03]). Most HCPs found the dashboard easy to use (74%) and helpful for improving conversations with participants about their treatment plan and progress (78%). Conclusion: This provider dashboard may facilitate discussions with patients about regular medication-taking, which can improve patient outcomes.

RESUMEN

Objective: Inpatient psychiatric admissions drive the financial burden of schizophrenia, and medication adherence remains challenging. We assessed whether aripiprazole tablets with sensor (AS; system includes ingestible event-marker sensor, wearable sensor patches, and smartphone application) could reduce psychiatric hospitalizations compared with oral standard-of-care (SOC) antipsychotics.Methods: This phase 3b, mirror-image clinical trial was conducted from April 29, 2019-August 11, 2020, in adults with schizophrenia with ≥ 1 hospitalization in the previous 48 months who had been prescribed oral SOC for the preceding 6 months (retrospective phase). All participants used AS for at least 3 months and up to 6 months. Primary endpoint was the inpatient psychiatric hospitalization rate in the modified intent-to-treat (mITT; n = 113) population during prospective months 1-3 versus retrospective phase. Proportion of days covered by medication was the secondary endpoint. Safety endpoints included adverse events related to the medication or patch and suicidality.Results: AS significantly reduced hospitalizations during prospective months 1-3 (-9.7%) and months 1-6 (-21.3% [P ≤ .001 for all comparisons]) in the mITT population versus the corresponding retrospective phase. AS use improved confirmed medication ingestion by 26.5 percentage points in prospective months 1-3 (P ≤ .001) and reduced PANSS scores. Patches were well-tolerated, and no participant reported changes in suicide risk.Conclusions: Compared with oral SOC, AS reduced inpatient psychiatric hospitalization rates for adults with mild-to-moderate schizophrenia. The AS system may aid medication ingestion and is associated with improvements in symptoms, potentially reducing acute-care needs among patients with schizophrenia.Trial Registration: ClinicalTrials.gov identifier: NCT03892889.

RESUMEN

The National Institute of Mental Health (NIMH) proposed the Research Domain Criteria (RDoC) initiative as an alternate way to organize research of mental illnesses, by looking at dimensions of functioning rather than being tied to categorical diagnoses. This paper briefly discusses the motivation for and organization of RDoC, and then explores the NIMH portfolio and recent work to monitor the utility and progress that RDoC has afforded developmental research. To examine how RDoC has influenced the NIMH developmental research portfolio over the last decade, we employed a natural language processing algorithm to identify the number of developmental science grants classified as incorporating an RDoC approach. Additional portfolio analyses examine temporal trends in funded RDoC-relevant grants, publications and citations, and research training opportunities. Reflecting on how RDoC has influenced the focus of grant applications, we highlight examples from research on Attention-Deficit Hyperactivity Disorder (ADHD), childhood irritability, and Autism Spectrum Disorder (ASD). Lastly, we consider how the dimensional and transdiagnostic approaches emphasized in RDoC have facilitated research on personalized intervention for heterogeneous disorders and preventive/early interventions targeting emergent or subthreshold psychopathology.

RESUMEN

The remarkably high and growing placebo response rates in clinical trials for CNS indications, such as depression and schizophrenia, constitute a major challenge for the drug development enterprise. Despite extensive literature on participant expectancies and other potent psychosocial factors that perpetuate placebo response, no empirically validated participant-focused strategies to mitigate this phenomenon have been available. This study evaluated the efficacy of the Placebo-Control Reminder Script (PCRS), a brief interactive procedure that educates participants about factors known to cause placebo response, which was administered prior to the primary outcome assessments to subjects with major depressive or psychotic disorders who had at least moderate depression. Participants were informed they would participate in a 2-week randomized clinical trial with a 50% chance of receiving either an experimental antidepressant medication or placebo. In actuality, all participants received placebo. Participants randomly assigned to receive the PCRS (n = 70) reported significantly smaller reductions (i.e., less placebo response) in depression than those who did not receive the PCRS (n = 67). The magnitude of this effect was medium (Cohen's d = 0.40) and was not significantly impacted by diagnostic status. The number of adverse events (i.e., nocebo effect) was also lower in the PCRS group, particularly in the first week of the study. These findings suggest that briefly educating participants about placebo response factors can help mitigate the large placebo response rates that are increasingly seen in failed CNS drug development programs.

RESUMEN

OBJECTIVE: This study examined data on acute (i.e., within 30 days) increases in suicides, help and information seeking, and service capacity after a celebrity suicide. METHODS: Daily suicide data, call volume to the National Suicide Prevention Lifeline (NSPL), and visits to two suicide prevention Web sites before and after entertainer Robin Williams' death on August 11, 2014, were examined. RESULTS: Before August 11 in 2012, 2013, and 2014, daily suicide deaths averaged between 113 and 117; in 2014, the count increased to 142, an increase not observed in 2012 and 2013. The number of calls to the NSPL rose by up to 300%, but answered calls decreased from an average of 71% to 57%. Visits to both Web sites also increased dramatically. CONCLUSIONS: Dramatic increases in all three measured outcomes in the days after a celebrity suicide were noted, suggesting the need for contingency plans to meet immediate increased demand.

RESUMEN

CONTEXT: Studies have shown that obesity is associated with increased sexual risk-taking, particularly among adolescent females, but the relationships between obesity, perceived weight and sexual risk behaviors are poorly understood. METHODS: Integrative data analysis was performed that combined baseline data from the 1994-1995 National Longitudinal Study of Adolescent Health (from 17,606 respondents in grades 7-12) and the 1997 National Longitudinal Survey of Youth (from 7,752 respondents aged 12-16). Using six sexual behaviors measured in both data sets (age at first intercourse, various measures of contraceptive use and number of partners), cluster analysis was conducted that identified five distinct behavior clusters. Multivariate ordinal logistic regression analysis examined associations between adolescents' weight status (categorized as underweight, normal-weight, overweight or obese) and weight perception and their cluster membership. RESULTS: Among males, being underweight, rather than normal-weight, was negatively associated with membership in increasingly risky clusters (odds ratio, 0.5), as was the perception of being overweight, as opposed to about the right weight (0.8). However, being overweight was positively associated with males' membership in increasingly risky clusters (1.3). Among females, being obese, rather than normal-weight, was negatively correlated with membership in increasingly risky clusters (0.8), while the perception of being overweight was positively correlated with such membership (1.1). CONCLUSIONS: Both objective and subjective assessments of weight are associated with the clustering of risky sexual behaviors among adolescents, and these behavioral patterns differ by gender.

RESUMEN

Background The patient-centered medical home (PCMH) provides a setting to enhance resident training in systems-based practice. Few studies have addressed the impact of PCMHs on resident knowledge and confidence. Objective The goal of this study was to evaluate resident knowledge, confidence, behavior, and patient outcomes in a PCMH. Methods Our curriculum emphasized patient panel report card interpretation, a telephone medicine curriculum, and interdisciplinary team-based care of chronic medical conditions. We measured resident satisfaction, knowledge, and confidence. Patient outcomes included hemoglobin A1c (HbA1c) and blood pressures. Prescores and postscores were compared using paired t tests for continuous measures and McNemar's test for binary measures. Results A total of 154 residents were eligible for the curriculum. All residents participated in the curriculum, though not all residents completed the evaluation. Completion rates for paired pre-post knowledge and confidence surveys were 38% and 37%, respectively. Nearly 80% (69 of 87) of residents indicated that the curriculum was above average or outstanding. Our evaluation revealed very small immediate improvements in knowledge and confidence. No significant improvement in patients' HbA1cs or blood pressures occurred after the curriculum. Conclusions Explicit training to work in a PCMH was feasible and resulted in high levels of resident satisfaction and immediate small improvements in knowledge and confidence.

RESUMEN

PURPOSE: To explore the effect of emotion priming and physician communication behaviors on optimism bias. MATERIALS AND METHODS: We conducted a 5 × 2 between-subject randomized factorial experiment using a Web-based interactive video designed to simulate a family meeting for a critically ill spouse/parent. Eligibility included age at least 35 years and self-identifying as the surrogate for a spouse/parent. The primary outcome was the surrogate's election of code status. We defined optimism bias as the surrogate's estimate of prognosis with cardiopulmonary resuscitation (CPR) > their recollection of the physician's estimate. RESULTS: Of 373 respondents, 256 (69%) logged in and were randomized and 220 (86%) had nonmissing data for prognosis. Sixty-seven (30%) of 220 overall and 56 of (32%) 173 with an accurate recollection of the physician's estimate had optimism bias. Optimism bias correlated with choosing CPR (P < .001). Emotion priming (P = .397), physician attention to emotion (P = .537), and framing of CPR as the social norm (P = .884) did not affect optimism bias. Framing the decision as the patient's vs the surrogate's (25% vs 36%, P = .066) and describing the alternative to CPR as "allow natural death" instead of "do not resuscitate" (25% vs 37%, P = .035) decreased optimism bias. CONCLUSIONS: Framing of CPR choice during code status conversations may influence surrogates' optimism bias.

RESUMEN

OBJECTIVE: To understand the incidence and persistence of severe obesity (≥1.2× 95th BMI percentile-for-age) in girls across the transition to adolescence, and map developmental trajectories of adolescent severe obesity in a high-risk sample. METHODS: We examined ten years of prospectively collected data from a population sample of urban girls (n=2,226; 53% African American, aged 7-10 in 2003-2004). We determined severe obesity prevalence and incidence by age. Logistic regression evaluated for secular trend in the association between age and severe obesity prevalence. Unconditional latent growth curve models (LGCMs) compared BMI development through the adolescence transition between girls with severe obesity versus healthy BMI. RESULTS: Severe obesity prevalence was 8.3% at age 7-10 and 10.1% at age 16-19 (white: 5.9%; African American: 13.2%; p<0.001). Age-specific prevalence increased more rapidly among the latest-born, versus earliest-born, girls (p=0.034). Incidence was 1.3% to 2.4% annually. When we compared 12-15 year-old girls with severe obesity versus healthy BMI, average body weight was already distinct 5 years earlier (16.5 kg versus 25.7 kg; p<0.001) and the BMI difference between groups increased annually. LCGMs between ages 7-10 and 11-14 indicated an increase of 3.32 kg/m2 in the healthy-BMI group and 8.50 kg/m2 in the severe obesity group, a 2.6-fold difference. CONCLUSIONS: Youth-onset severe obesity warrants particular concern in urban girls due to high prevalence and an increasing secular prevalence trend. Late childhood and early adolescence may represent a key developmental window for prevention and treatment, but is too late to prevent youth-onset severe obesity entirely.

RESUMEN

INTRODUCTION: The literature on environment and obesity is characterized by studies that are often cross-sectional and lack racial diversity. This study examined associations between neighborhood features and BMI development over 6 years in an urban sample of 2,295 girls (56% African American; mean age at baseline, 11.2 years) in 2004. Analyses were conducted in 2011-2015. METHODS: Girls, caregivers, and study staff completed annual neighborhood questionnaires. Linear mixed-effects modeling examined annual changes in neighborhood features and BMI and assessed whether baseline neighborhood features modified BMI growth over time. RESULTS: At baseline, 40% of participants were overweight/obese. Participants' neighborhoods had few neighborhood problems, moderate levels of safety issues and inconvenient features, low levels of neighborhood disorder, few cases of loitering youth, and substantial traffic volume. Adverse neighborhood features were more common for African American than white participants. Neighborhood features were relatively stable over the follow-up period. African American girls with helpful neighbors had lower annual BMI growth (-0.09 kg/m(2)) than others. For white girls, BMI increased more for girls with helpful neighbors (+0.09 kg/m(2) annually). Regardless of race, living in a U.S. Census tract with low levels of educational achievement was linked with higher BMI growth (an additional 0.07 kg/m(2) annually). Girls living in Census tracts with high (versus low) levels of poverty gained an additional 0.08 kg/m(2) gain annually. CONCLUSIONS: Social environment features are associated with BMI change in white and African American urban girls and may be helpful for identifying girls at risk for early adolescent weight gain.

RESUMEN

OBJECTIVE: To evaluate racial/ethnic differences in contraceptive use among women who do not desire future pregnancy. STUDY DESIGN: We used the 2006-2010 National Survey of Family Growth to examine the associations between race/ethnicity and 1) use of any contraceptive method at last heterosexual intercourse and 2) effectiveness of contraceptive method used among women who stated that they did not desire any (more) children. We conducted multivariable logistic regression to assess the independent effect of race/ethnicity on these outcomes, adjusting for socio-demographic factors, reproductive characteristics, and indicators of healthcare access and utilization. RESULTS: The study sample consisted of 2900 women, aged 15-44 years. The vast majority of women (91.2%) used contraception at last sex, although this varied significantly by race/ethnicity (p<.01). In the fully adjusted model controlling for demographic and reproductive characteristics as well as healthcare access, compared to whites, black women were significantly less likely to use any contraception at last sex (OR: 0.43; 95% CI: 0.27-0.73), while there was no significant difference for Hispanic women (OR: 0.95; 95% CI: 0.52-1.72). Among women who used a method at last sex, the type of contraceptive method varied significantly by race/ethnicity in bivariate analysis (p<.01), although most women (59%) used a highly effective method. In the fully adjusted model, racial/ethnic differences were no longer significant. CONCLUSIONS: In this nationally representative cohort of women who report that they do not desire (more) children, black women were significantly less likely than white women to use any contraception at last intercourse; this difference did not appear to be due to differential access to health care. IMPLICATIONS: Significant racial/ethnic differences exist in contraceptive use among women who have completed childbearing, which do not appear to be explained by differential socioeconomic status, reproductive characteristics or utilization of healthcare. Other factors, including social mobility and locus of reproductive control, that may contribute to these variations should be further explored.

RESUMEN

CONTEXT: Hospitals vary substantially in their end-of-life (EOL) treatment intensity. It is unknown if patterns of EOL treatment intensity are consistent across conditions. OBJECTIVES: To explore the relationship between hospitals' cancer- and non-cancer-specific EOL treatment intensity. METHODS: We conducted a retrospective cohort analysis of Pennsylvania acute care hospital admissions for either cancer or congestive heart failure (CHF) and/or chronic obstructive pulmonary disease (COPD) between 2001 and 2007, linked to vital statistics through 2008. We calculated Bayes's shrunken case-mix standardized (observed-to-expected) ratios of intensive care and life-sustaining treatment use among two EOL cohorts: those prospectively identified at high probability of dying on admission and those retrospectively identified as terminal admissions (decedents). We then summed these to create a hospital-specific prospective and retrospective overall EOL treatment intensity index for cancer vs. CHF/COPD. RESULTS: The sample included 207,523 admissions with 15% or greater predicted probability of dying on admission among 172,041 unique adults and 120,372 terminal admissions at 166 hospitals; these two cohorts overlapped by 52,986 admissions. There was substantial variation between hospitals in their standardized EOL treatment intensity ratios among cancer and CHF/COPD admissions. Within hospitals, cancer- and CHF/COPD-specific standardized EOL treatment intensity ratios were highly correlated for intensive care unit (ICU) admission (prospective ρ = 0.81; retrospective ρ = 0.78), ICU lengths of stay (ρ = 0.76; 0.64), mechanical ventilation (ρ = 0.73; 0.73), and hemodialysis (ρ = 0.60; 0.71) and less highly correlated for tracheostomy (ρ = 0.43; 0.53) and gastrostomy (ρ = 0.29; 0.30). Hospitals' overall EOL intensity index for cancer and CHF admissions were correlated (prospective ρ = 0.75; retrospective ρ = 0.75) and had equal group means (P-value = 0.631; 0.699). CONCLUSION: Despite substantial difference between hospitals in EOL treatment intensity, within-hospital homogeneity in EOL treatment intensity for cancer- and non-cancer populations suggests the existence of condition-insensitive institutional norms of EOL treatment.

RESUMEN

BACKGROUND: Little is known about acute hemodialysis in the US. Here we describe predictors of receipt of acute hemodialysis in one state and estimate the marginal impact of acute hemodialysis on survival after accounting for confounding due to illness severity. MATERIALS AND METHODS: This is a retrospective cohort study of acute-care hospitalizations in Pennsylvania from October 2005 to December 2007 using data from the Pennsylvania Health Care Cost Containment Council. Exposure variable is acute hemodialysis; dependent variable is survival following acute hemodialysis. We used multivariable logistic regression to determine propensity to receive acute hemodialysis and then, for a Cox proportional hazards model, matched acute hemodialysis and non-acute hemodialysis patients 1∶5 on this propensity. RESULTS: In 2,131,248 admissions of adults without end-stage renal disease, there were 6,657 instances of acute hemodialysis. In analyses adjusted for predicted probability of death upon admission plus other covariates and stratified on age, being male, black, and insured were independent predictors of receipt of acute hemodialysis. One-year post-admission mortality was 43% for those receiving acute hemodialysis, compared to 13% among those not receiving acute hemodialysis. After matching on propensity to receive acute hemodialysis and adjusting for predicted probability of death upon admission, patients who received acute hemodialysis had a higher risk of death than patients who did not over at least 1 year of follow-up (hazard ratio 1·82, 95% confidence interval 1·68-1·97). CONCLUSIONS: In a populous US state, receipt of acute hemodialysis varied by age, sex, race, and insurance status even after adjustment for illness severity. In a comparison of patients with similar propensity to receive acute hemodialysis, those who did receive it were less likely to survive than those who did not. These findings raise questions about reasons for lack of benefit.

RESUMEN

BACKGROUND: As an alternative to current methods of local nerve block, we studied the feasibility of producing ankle block in the rat with IV injection of magnetic nanoparticles (MNPs) associated with ropivacaine and application of a magnet at the ankle. METHODS: The anesthetic effect of magnet-directed ropivacaine-associated MNPs (MNP/Ropiv) was tested in the rat using paw withdrawal latencies from thermal stimuli applied to the hindpaw. The MNP/Ropiv complexes consisted of 0.7% w/v ropivacaine and 0.8% w/v MNPs containing 12% w/w magnetite (F3O4). The effect of IV injection of MNP/Ropiv with 15, 30, and 60-minute magnet application to the right ankle was compared with the effect without magnet application on the left hindpaw, to conventional ankle block with 0.1% or 0.2% ropivacaine, and to IV injection of MNPs alone with 30-minute magnet application to the right ankle. In addition, the pharmacokinetics of the MNP/Ropiv complexes were determined. RESULTS: IV injection of MNP/Ropiv with magnet application at the ankle significantly increased paw withdrawal latencies from thermal stimuli compared with pretreatment baselines in the same paw (P < 0.0001) and compared with the contralateral paw without magnet application (P < 0.0001). IV injection of MNPs alone had no significant effect on paw withdrawal latency. Absolute ropivacaine concentrations in ankle tissue, and ankle tissue-to-plasma concentration ratios were higher in the MNP/Ropiv group with 30-minute magnet application compared with MNP/Ropiv group without magnet application (mean ± SEM, 150 ± 10 ng/g vs 105 ± 15 ng/g, respectively, and 6.1 ± 0.8 vs 4.2 ± 0.7, respectively). CONCLUSIONS: The current study establishes proof of principle that it is possible to produce ankle block in the rat by IV injection of MNP/Ropiv complexes and magnet application at the ankle. The results indicate that further study of this approach is warranted.

RESUMEN

PURPOSE: To study selective use of antibiotic-impregnated catheters in children at increased risk of venous catheter-related infections (CRIs). MATERIALS AND METHODS: From December 2008 to June 2009, 428 peripherally inserted central catheters (PICCs) were placed by the interventional radiology service of a large metropolitan children's hospital. This retrospective study analyzed demographic and outcome data for the 125 patients in this group at high risk for venous CRI. Patients at high risk were those with active systemic infection, previous complicated central venous access, intensive care unit (ICU) admission, intestinal failure, transplantation, complex congenital heart disease, or renal failure. Patients (age, 7.6 y ± 7.0; 73 male and 52 female) received a conventional or antibiotic-impregnated PICC, with 17 receiving more than one catheter. RESULTS: Of the 146 of 428 qualifying patient encounters (34%), 53 patients received an antibiotic-impregnated PICC and 93 received a conventional PICC, representing 5,080 total catheter-days (CDs). The rates of CRIs per 1,000 CDs, including catheter exit site infections and catheter-related bloodstream infections, were 0.86 for antibiotic-impregnated PICCs and 5.5 for conventional PICCs (P = .036). A propensity-based model predicts 15-fold greater infection-free survival over the lifetime of the catheter in patients who receive an antibiotic-impregnated PICC (P < .001). Antibiotic-impregnated PICC recipients with active infection or ICU admission at the time of insertion had no catheter-associated infections, compared with 3.42 and 9.46 infections per 1,000 CDs, respectively, for patients who received conventional PICCs. Patients with intestinal failure had 1.49 and 10 infections per 1,000 CDs with antibiotic-impregnated versus conventional PICCs, respectively.

RESUMEN

OBJECTIVE: To develop, pilot, and test the effectiveness of a clear health communication curriculum to improve resident knowledge, attitudes, and skills regarding health literacy. METHODS: Thirty-one internal medicine residents participated in a small group curriculum that included didactic teaching, practice with a standardized patient, and individualized feedback on videotaped encounters with real patients. Outcomes were assessed using a pre-post survey and a communication skills checklist. RESULTS: Mean knowledge scores increased significantly from 60.3% to 77.6% (p<0.001). Residents also reported increased familiarity with the concept of health literacy (mean response 3.2 vs. 4.5 on a 5 point scale), importance placed on health literacy (4.2 vs. 4.9), frequency of considering health literacy in patient care (3.3 vs. 4.0), and confidence in communicating with low literacy patients (3.3 vs. 4.1) (all p<0.001). Use of plain language increased significantly from 33% to 86% (p=0.023). There were nonsignificant increases in the use of teach-back (0-36%, p=0.116) and encouraging questions (0-14%, p=0.502). CONCLUSION: Training in clear health communication improves resident knowledge, attitudes, and skills regarding health literacy. PRACTICE IMPLICATIONS: The increased use of clear health communication techniques can significantly improve the care and outcomes of vulnerable patients with limited health literacy.

RESUMEN

The Work Preference Inventory (WPI) is a four-factor, 30-item measure that assesses work motivation. Used to help individuals choose appropriate career paths, its length contributes to response burden, especially when combined with other measures. We aimed to develop a shortened, valid, and reliable version of the WPI. Trainees at the University of Pittsburgh's Institute for Clinical Research Education completed the 30-item WPI between 2007 and 2012. We conducted exploratory and confirmatory factor analyses to reduce the number of items. Of the 402 eligible trainees, 371 (92%) provided data for the exploratory factor analysis (EFA), and 134 of the eligible 144 trainees (93%) provided data for the confirmatory factor analysis (CFA). EFA revealed four factors that were roughly equivalent to those of the original. CFA used the three items with the highest loadings on each factor, with two items removed due to low loadings and R-squareds, resulting in a 10-item scale. Cronbach's alpha for each of the four factors ranged from 0.68 to 0.76. Factors in the WPI-10 were strongly and significantly associated with factors in the original WPI, indicating strong validity of the shortened measure. The WPI-10 shows evidence for similar validity and reliability to the original instrument while reducing respondent burden.

RESUMEN

While physical and human capital are established as important predictors of success among early-career clinical investigators, less is known about the role of social capital. The authors aimed to develop a brief scale to assess social capital in this population and test its reliability and validity. A three-item assessment was developed based on a conceptual framework and measures of social capital from other fields and was administered to 414 clinical research trainees at the University of Pittsburgh in 2007-2012. The measure exhibited good internal consistency reliability (α = 0.71) and a normal distribution. On a 10-point scale, mean social capital was 6.4 (SD = 1.7). Social capital was significantly associated with 7 of the 9 expected constructs: sex, age, confidence in research skills, work-related motivation, burnout, and social support. Exploratory multivariable regression analysis demonstrated that social capital was most strongly associated with higher research confidence (ß = 0.35, p < 0.001), higher extrinsic motivation (ß = 0.50, p = 0.003), and lower burnout (ptrend = 0.02). This three-item scale measures social capital in this population with adequate internal consistency reliability, face validity, and construct validity. This brief assessment provides a tool that may be valuable to benchmark social capital of clinical research trainees and to better contextualize programmatic and trainee outcomes.

RESUMEN

AIMS: The aim of this study is to assess the effect of brief motivational enhancement intervention postpartum alcohol use. DESIGN: This study is a single-blinded, randomized controlled effectiveness trial in which pregnant women were assigned to receive usual care or up to 5 face-to-face brief motivational enhancement sessions lasting 10-30 minutes each and occurring at study enrollment, 4 and 8 weeks after enrollment, 32 weeks of gestation, and 6 weeks postpartum. SETTING: The setting is in a large, urban, obstetrics clinic. PARTICIPANTS: Participants were women who were ≥ 18 years old, <20 weeks of gestation, and consumed alcohol during pregnancy. Of 3438 women screened, 330 eligible women were assigned to usual care (n = 165) or intervention (n=165). Due to missing data, we analyzed 125 in the intervention group and 126 in the usual care group. MEASUREMENTS: The measurements were the proportion of women with any alcohol use and the number of drinks per day, reported via follow-up telephone interviews at 4 and 8 weeks after enrollment, 32 weeks of gestation, and 6 weeks, 6 months, and 12 months postpartum. FINDINGS: In random effects models adjusted for confounders, the intervention group was less likely to use any alcohol (odds ratio 0.50; 95% confidence interval [CI], 0.23-1.09; P=0.08) and consumed fewer drinks per day (coefficient -0.11; 95% CI -0.23-0.01; P=0.07) than, the usual care group in the postpartum period but these differences were non-significant. Missing data during the prenatal period prevented us from modeling prenatal alcohol use. CONCLUSIONS: Brief motivational enhancement intervention delivered in an obstetrical outpatient setting did not conclusively decrease alcohol use during the postpartum period.

RESUMEN

BACKGROUND: Seasonal fluxes in 25-hydroxyvitamin D (25(OH)D) in children can affect bone turnover, and in turn potentially affect bone accrual and peak bone mass. The aim of this study was to examine the effect of seasonal flux on the association among 25(OH)D, parathyroid hormone (PTH) and markers of bone turnover in pre- and early pubertal black children and white children. METHODS: Data were collected during summer (June-September) and winter (December-March) in 6-12-year-old children. Measurements included serum 25(OH)D, PTH, osteocalcin (OC), collagen type 1 cross-linked C-telopeptide (CTx), dietary intake of vitamin D and calcium, skin color, sunlight exposure, and body mass index (BMI). RESULTS: A total of 138 children (mean age, 9.1 ± 1.7 years; black, n = 94; male, n = 81) were studied. 25(OH)D was higher (41.2 ± 13 vs 34.5 ± 11.1 ng/mL; P < 0.001) and CTx was lower (0.8 ± 0.3 vs 0.9 ± 0.5 ng/mL; P < 0.001) in all participants during summer when compared to winter. Furthermore, seasonal differences in CTx were more pronounced in black children (summer, 0.7 ± 0.3 vs winter, 1.0 ± 0.5 ng/mL; P < 0.001). PTH was a significant predictor of serum CTx and OC after adjusting for race, season, Tanner stage, dietary calcium, skin color and BMI. CONCLUSION: 25(OH)D declined significantly in both black children and white children during winter. CTx significantly increased during winter in black children compared to white children, suggesting increased rates of resorption in black children during winter. Benefits of enhancement of wintertime vitamin D status on bone health need further exploration.
