Parent involvement is a robust predictor of academic achievement, but little is known about school- and home-based involvement in immigrant families. Drawing on ecological theories, the present study examined contextual characteristics as predictors of parent involvement among Afro-Caribbean and Latino parents of young students in urban public schools. Socioeconomic disadvantage was associated with lower home-based involvement. Several factors were associated with higher involvement, including parents' connection to their culture of origin and to U.S. culture, engagement practices by teachers and parent-teacher ethnic consonance (for Latinos only). Findings have implications for promoting involvement among immigrant families of students in urban schools.

Neoliberal ideology champions privatization, personal responsibility, and entrepreneurship, and public health practice under neoliberalism channels this individualized focus. Though this new public health' may be seen as a liberalizing practice of governance, in which individuals are free to maximize health and autonomy, this privatization also embeds responsibility within the individual without regard to existing or resulting inequalities. This paper examines the presence of neoliberal ideology in the narratives and subjectivities as it relates to HIV prevention in the lives of young gay and bisexual men living in New York City. We also seek to further the critique of neoliberalism in HIV prevention. The men often saw themselves or others as rational, autonomous agents, yet there were also clear instances where social and structural factors were at play. These factors influenced a subjectivity existing outside the narrow, atomistic framework of neoliberalism. Implicit moral hierarchies arose from notions of personal responsibility and recklessness, pitting men against each other and potentially inhibiting social and community prevention efforts. Further, neoliberal ideology obscured the social and structural mechanisms at play, such as racial inequality, economic inequality, homophobia, and sexual shaming. In contrast to the ideology of neoliberal public health, we must explicitly consider the resources, opportunities, and social conditions that shape autonomy and subjectivity among young gay and bisexual men.

BACKGROUND: Tobacco use and unhealthy lifestyle habits amongst youth contribute to most major health issues in the United Arab Emirates (UAE) and worldwide. However up to date and comprehensive statistics are not available on the current behavior, experimentation and environmental influences on teenagers in the UAE's expatriate community, who are greatly impacted by the country's culture and environment, as well as bringing influences from their cultures of origin. Expatriates comprise a majority of the UAE population, making them an important subset of the population to study. METHOD: To address this gap in knowledge, a survey was conducted to collect information on tobacco use, physical activity and nutrition behaviors, anti-tobacco media/legislation effectiveness and health education gaps. RESULTS: Our results provide a summary on each of these topics with regards to ninth grade expatriates in the UAE. We offer the first statistics on dokha use in this age group and uncover signs of underlying eating disorders. CONCLUSIONS: In conclusion, we call for a tobacco use, nutrition and physical activity intervention targeted at this age group of UAE expatriates.

INTRODUCTION: Dementia with Lewy bodies (DLB) is a challenge to diagnose, particularly outside of expert centers with long delays in diagnosis leading to significant burden to patients and caregivers. While consensus criteria have excellent specificity, there is no standardized way to assess symptoms reducing sensitivity. We developed the Lewy Body Composite Risk Score (LBCRS) from autopsy-verified cases to improve the ability to detect DLB in clinic and research populations. METHODS: The LBCRS was tested in a consecutive series of 256 patients compared with the Clinical Dementia Rating and gold standard measures of cognition, motor symptoms, function, and behavior. Psychometric properties including floor and ceiling effects; concurrent, construct, and known-groups validity, and internal consistency of the LBCRS were determined. Receiver operator characteristic (ROC) curves assessed the ability of LBCRS to differentiate: (a) DLB from Alzheimer's disease (AD); (b) DLB from all dementia, and (c) Mild cognitive impairment (MCI) due to DLB from MCI due to AD. The LBCRS was completed independent of the clinical evaluation. RESULTS: Mean LBCRS scores were significantly different between DLB and AD (6.1+/-2.0 vs. 2.4+/-1.3, p<.001) and between MCI-DLB vs MCI-AD (3.2+/-0.9 vs. 1.0+/-0.8, p<.001). The LBCRS was able to discriminate DLB from other causes of dementia. Using a cut-off score of 3, areas under ROC for DLB vs. AD = 0.93 (0.89-0.98), and for MCI-DLB vs. MCI-AD = 0.96 (0.91-1.0). DISCUSSION: The LBCRS increases diagnostic probability that Lewy body pathology is contributing to the dementia syndrome and should improve clinical detection and enrollment for clinical trials.

BACKGROUND: Baseline health and functional vulnerabilities increase the risk for complications in persons with dementia and predispose family caregivers (FCGs) to increased stress. METHODS: This secondary analysis used a combined quantitative and qualitative approach. Regression analyses examined the contribution of patient and FCG characteristics to FCG anxiety. Interviews with FCGs explored the experiences and responses of FCGs during hospitalization of their family member with dementia. RESULTS: Lower patient physical function and higher caregiver strain were associated with higher FCG anxiety. FCGs described the following themes related to the hospitalization: (1) added strain, (2) care-related worries, (3) keeping vigil, (4) need to be heard, and (5) enablers of FCGs. CONCLUSIONS: Routine evaluation of caregiver strain and baseline patient function is integral to informing the transitional planning for persons with dementia. The FCG responses suggest that a multifactorial approach (family-centered policies of partnership in care, staff education addressing the specialized needs of patients and family members, and attention to promoting functional recovery) may benefit both hospitalized patients with dementia as well as FCGs and warrants future research.

Given the heightened risk for HIV and other STIs among young men who have sex with men (YMSM) as well as the racial/ethnic disparities in HIV/STI risk, an understanding of longitudinal trends in sexual behaviors is warranted as YMSM emerge into adulthood. Drawing from an ongoing prospective cohort study, the present analysis employed latent growth curve modeling to examine trends in distinct types of sexual activity without condoms over time in sample of YMSM and examine differences by race/ethnicity and perceived familial socioeconomic status (SES). Overall, White and Mixed race YMSM reported more instances of oral sex without condoms as compared to other racial/ethnic groups with rates of decline over time noted in Black YMSM. White YMSM also reported more receptive and insertive anal sex acts without a condom than Black YMSM. Declines over time in both types of anal sex acts without condoms among Black men were noted when compared to White men, while increases over time were noted for mixed race YMSM for condomless insertive anal sex. The effects for race/ethnicity were attenuated with the inclusion of perceived familial SES in these models. These findings build on previous cross sectional studies showing less frequent sex without condoms among Black YMSM despite higher rates of HIV incidence in emerging adulthood, as well as the importance of considering economic conditions in such models. Efforts to understand racial/ethnic disparities in HIV/STIs among YMSM must move beyond examination of individual-level sexual behaviors and consider both race/ethnicity and socioeconomic conditions in order to evaluate how these factors shape the sexual behaviors of YMSM.

To date, only one study has examined test-retest reliability of resting state fMRI (R-fMRI) in children, none in clinical developing groups. Here, we assessed short-term test-retest reliability in a sample of 46 children (11-17.9 years) with attention-deficit/hyperactivity disorder (ADHD) and 57 typically developing children (TDC). Our primary test-retest reliability measure was the intraclass correlation coefficient (ICC), quantified for a range of R-fMRI metrics. We aimed to (1) survey reliability within and across diagnostic groups, and (2) compare voxel-wise ICC between groups. We found moderate-to-high ICC across all children and within groups, with higher-order functional networks showing greater ICC. Nearly all R-fMRI metrics exhibited significantly higher ICC in TDC than in children with ADHD for one or more regions. In particular, posterior cingulate and ventral precuneus exhibited group differences in ICC across multiple measures. In the context of overall moderate-to-high test-retest reliability in children, regional differences in ICC related to diagnostic groups likely reflect the underlying pathophysiology for ADHD. Our currently limited understanding of the factors contributing to inter- and intra-subject variability in ADHD underscores the need for large initiatives aimed at examining their impact on test-retest reliability in both clinical and developing populations.

OBJECTIVES: As part of a large randomized controlled trial, the authors assessed the impact of 2 early primary care parenting interventions-the Video Interaction Project (VIP) and Building Blocks (BB)-on the use of physical punishment among low-income parents of toddlers. They also determined whether the impact was mediated through increases in responsive parenting and decreases in maternal psychosocial risk. METHODS: Four hundred thirty-eight mother-child dyads (161 VIP, 113 BB, 164 Control) were assessed when the children were 14 and/or 24 months old. Mothers were asked about their use of physical punishment and their responsive parenting behaviors, depressive symptoms, and parenting stress. RESULTS: The VIP was associated with lower physical punishment scores at 24 months, as compared to BB and controls. In addition, fewer VIP parents reported ever using physical punishment as a disciplinary strategy. Significant indirect effects were found for both responsive parenting and maternal psychosocial risk, indicating that the VIP affects these behaviors and risk factors, and that this is an important pathway through which the VIP affects the parents' use of physical punishment. CONCLUSION: The results support the efficacy of the VIP and the role of pediatric primary care, in reducing the use of physical punishment among low-income families by enhancing parent-child relationships. In this way, the findings support the potential of the VIP to improve developmental outcomes for at-risk children.
