Intervening to Reduce Sedentary Behaviors and Childhood Obesity among School-Age Youth: A Systematic Review of Randomized Trials

Objective. To assess the effectiveness of interventions that focus on reducing sedentary behavior (SB) among school-age youth and to identify elements associated with interventions' potential for translation into practice settings. Methods. A comprehensive literature search was conducted using 4 databases for peer-reviewed studies published between 1980 and April 2011. Randomized trials, which lasted at least 12 weeks, aimed at decreasing SB among children aged 6 to 19 years were identified. Results. Twelve studies were included; 3 focused only on SB, 1 focused on physical activity (PA), 6 were combined SB and PA interventions, and 2 studies targeted SB, PA, and diet. The majority of the studies were conducted in a school setting, while others were conducted in such settings as clinics, community centers, and libraries. Conclusions. Overall, interventions that focused on decreasing SB were associated with reduction in time spent on SB and/or improvements in anthropometric measurements related to childhood obesity. Several of the studies did consider elements related to the intervention's potential for translation into practice settings

Treating Obesity in Latino Children: A Systematic Review of Current Interventions

Childhood obesity remains a significant public health issue in the U.S. and globally. Rates are disproportionately higher in Latinos than other ethnic groups. This review provides a qualitative synthesis of the current evidence for childhood obesity treatment interventions among Latino children. A systematic search was performed in PubMed, Web of Science and Google Scholar for articles published from September 2010 to December 2015. Randomized controlled trials treating childhood overweight/obesity in Latino children ages 5-19 focused on diet and/or physical activity (PA) behaviors were included. Of the records initially identified (n=1,592), 11 studies met the inclusionary criteria. The majority included a family-based component (n=8; 73%). Nearly half (n=5) focused on children ages 5-12, with three specifically developed for the pre-adolescence stage (ages 8-12). Nine studies acknowledged cultural tailoring, most frequently by seeking input from their intended population and utilizing bilingual delivery staff. Improvements in anthropometric measures (e.g. body mass index (BMI) z-score) were observed in 55% of the studies (n=6). Many interventions with a combined focus of diet and PA, in the form of nutrition education in a group setting and in-person activity/exercise sessions and incorporated a parent/family component reported positive anthropometric results. Three (27%) studies included a follow-up period, all of which observed a sustained decrease in BMI over time. Overall, family-based interventions focusing on both diet and PA demonstrated promising results. However, additional research incorporating a follow-up period is warranted to assess sustainability of these outcomes. Additionally, more interventions could be developed specifically for the critical developmental stage of pre-adolescence

Combined Tractional and Rhegmatogenous Retinal Detachment in Proliferative Diabetic Retinopathy in the Anti-VEGF Era

Purpose. To investigate the clinical features, surgical outcomes, and prognostic factors of combined rhegmatogenous and tractional detachment (combined RD) in proliferative diabetic retinopathy (PDR) in recent years. Methods. Medical records of PDR and combined RD treated with vitrectomy from 2008 to 2013 were retrospectively reviewed. Results. A total of 57 eyes from 49 patients were included. Nine eyes had received panretinal photocoagulation (PRP) and 7 eyes had intravitreal bevacizumab (IVB) within 3 months before RD developed. Thirty-eight eyes (66.7%) had ≧3 sites of broad adhesion of fibrovascular proliferation (FVP). Thirty-three eyes (57.9%) showed active FVP. Thirty-four eyes (59.6%) had extent of RD involving 3 or 4 quadrants. The primary reattachment rate was 93.0%, and the final visual acuity (VA) improved by more than 3 lines in 80.7% of eyes. Neovascular glaucoma occurred in 4 eyes postoperatively. Poor preoperative VA, severe vitreoretinal adhesion, and broad extent of RD had significant correlation with poor visual outcomes. Conclusion. PRP or IVB might play a role in provoking combined RD. The anatomical and functional success rates of surgery were high. Poor preoperative VA and severe proliferations predicted poor visual outcomes

Caregiver Participation Engagement in Child Mental Health Prevention Programs: a Systematic Review

Prevention programs are a key method to reduce the prevalence and impact of mental health disorders in childhood and adolescence. Caregiver participation engagement (CPE), which includes caregiver participation in sessions as well as follow-through with homework plans, is theorized to be an important component in the effectiveness of these programs. This systematic review aims to (1) describe the terms used to operationalize CPE and the measurement of CPE in prevention programs, (2) identify factors associated with CPE, (3) examine associations between CPE and outcomes, and (4) explore the effects of strategies used to enhance CPE. Thirty-nine articles representing 27 unique projects were reviewed. Articles were included if they examined CPE in a program that focused to some extent on preventing child mental health disorders. There was heterogeneity in both the terms used to describe CPE and the measurement of CPE. The majority of projects focused on assessment of caregiver home practice. There were no clear findings regarding determinants of CPE. With regard to the impact of CPE on program outcomes, higher levels of CPE predicted greater improvements in child and caregiver outcomes, as well as caregiver-child relationship quality. Finally, a small number of studies found that motivational and behavioral strategies (e.g., reinforcement, appointment reminders) were successful in promoting CPE. This review highlights the importance of considering CPE when developing, testing, and implementing prevention programs for child mental health disorders. Increased uniformity is needed in the measurement of CPE to facilitate a better understanding of determinants of CPE. In addition, the field would benefit from further evaluating strategies to increase CPE as a method of increasing the potency of prevention programs

Exploring the use of an iPhone App: a Novel Approach to Dietary Assessment

Recent advancements in smartphone technology have provided new methods of dietary assessment. An iTunes application (app) called Meal Snap lets users take pictures of the meal they eat, and then estimates the calories of the food items eaten. We conducted a pilot study to explore the user-friendliness and calorie estimation functions of the Meal Snap app. Two female nutrition graduate students pilot-tested the Meal Snap app. Using the app, each student took pictures of foods and drinks consumed daily for two weeks. The data were analyzed using the Nutritionist ProTM software, version 4.4.0. The mean daily caloric intake obtained from the Meal Snap was then compared with that of Nutritionist ProTM. Paired samples t-tests and correlations were carried out using SPSS, version 19. Results indicated there was no significant difference in mean daily caloric consumption between Meal Snap and Nutritionist ProTM (p= 0.706). Additionally, there was a significant correlation between Meal Snap and Nutritionist ProTM calorie counts (Spearman r= 0.625, p\u3c 0.001). It took about 35 minutes per week (or 5 minutes/day) to snap pictures and edit descriptions, whereas entering data for calorie analysis with Nutritionist ProTM took about 85-90 minutes per week (about 13 minutes/day). Findings suggest that Meal Snap may be a user-friendly tool to estimate dietary intake. Future research should include a larger sample and people of diverse ethnic backgrounds, dietary habits and age groups

Building relationships and facilitating immigrant community integration: An evaluation of a Cultural Navigator Program

Despite the United States’ long history of immigration, large and small communities around the country struggle to integrate newcomers into the social, economic, cultural, and political spheres of society. Utilizing results from the program evaluation of one public library’s Cultural Navigator Program (CNP), the authors illustrate how communities and public institutions can promote integration and relationship building between newly arrived immigrants and long-time residents. Existing social networks, conceptualized in this article as social capital, within receiving communities were leveraged to build capacity among newly arrived immigrants and foster inclusivity and integration at the community level. As a place of intervention, public libraries are suggested as a safe and shared space where community integration can be fostered. The program model is provided as an approach to immigrant community integration. Insights derived from the evaluation inform a discussion on engaging approaches to immigrant integration. The CNP utilized community networks to deliberately and systematically facilitate integration and relationship building between newly arrived immigrants and community members. Lessons learned and recommendations for program evaluators and administrators are provided

Involvement of an Actomyosin Contractile Ring in Saccharomyces cerevisiae Cytokinesis

In Saccharomyces cerevisiae, the mother cell and bud are connected by a narrow neck. The mechanism by which this neck is closed during cytokinesis has been unclear. Here we report on the role of a contractile actomyosin ring in this process. Myo1p (the only type II myosin in S. cerevisiae) forms a ring at the presumptive bud site shortly before bud emergence. Myo1p ring formation depends on the septins but not on F-actin, and preexisting Myo1p rings are stable when F-actin is depolymerized. The Myo1p ring remains in the mother–bud neck until the end of anaphase, when a ring of F-actin forms in association with it. The actomyosin ring then contracts to a point and disappears. In the absence of F-actin, the Myo1p ring does not contract. After ring contraction, cortical actin patches congregate at the mother–bud neck, and septum formation and cell separation rapidly ensue. Strains deleted for MYO1 are viable; they fail to form the actin ring but show apparently normal congregation of actin patches at the neck. Some myo1Δ strains divide nearly as efficiently as wild type; other myo1Δ strains divide less efficiently, but it is unclear whether the primary defect is in cytokinesis, septum formation, or cell separation. Even cells lacking F-actin can divide, although in this case division is considerably delayed. Thus, the contractile actomyosin ring is not essential for cytokinesis in S. cerevisiae. In its absence, cytokinesis can still be completed by a process (possibly localized cell–wall synthesis leading to septum formation) that appears to require septin function and to be facilitated by F-actin
