Bariatric surgery performed at hospitals with more than 100 cases annually is associated with a shorter length of stay, lower morbidity and mortality, and decreased costs. This volume-outcome relationship is even more pronounced for a subset of patients older than 55 years, for whom in-hospital mortality was 3-fold higher at low-volume compared with high-volume hospitals. High-volume hospitals also have a lower rate of overall postoperative and medical care complications, which may be related in part to formalization of the structures and processes of care.

This interventional study provides Class II evidence that atomoxetine (target dosage = 80 mg/day) is not efficacious in improving clinically significant depression in PD.

Objective: This study sought to evaluate the feasibility of a pilot, dyad-based lifestyle intervention, the Unidas por la Vida program, for improving weight loss and dietary intake among high-risk Mexican American mothers who have Type 2 diabetes and their overweight/obese adult daughters. Method: Mother-daughter dyads (N ϭ 89) were recruited from two federally qualified health centers and randomly assigned to either the Unidas intervention or to the control condition. The 16-week Unidas intervention consisted of the following: (a) four group meetings, (b) eight home visits, and (c) booster telephone calls by a lifestyle community coach. The control condition consisted of educational materials mailed to participants' homes. Participants completed surveys at T1 (baseline) and T2 (16 weeks) that assessed various demographic, social network involvement, and dietary variables. Results: Unidas participants lost significantly more weight at T2 (p Ͻ .003) compared with the control participants. Furthermore, intervention participants also were more likely to be eating foods with lower glycemic load (p Ͻ .001) and less saturated fat (p ϭ .004) at T2. Unidas participants also reported a significant increase in health-related social support and social control (persuasion control only) and a decrease in undermining. Conclusions: The Unidas program promoted weight loss and improved dietary intake, as well as changes in diet-related involvement of participants' social networks. The results from this study demonstrate that interventions that draw upon multiple people who share a health-risk have the potential to foster significant changes in lifestyle behaviors and in social network members' health-related involvement. Future research that builds on these findings is needed to elucidate the specific dyadic and social network processes that may drive health behavior change.

Hypothesis: An increase in national utilization of bariatric surgery correlates with the dissemination of laparoscopic bariatric surgery.

IMPORTANCE Mental health (MH) conditions are undertreated in late life. It is important to identify treatment strategies that address variability in treatment content and delivery and take individual-specific symptoms into account, particularly among low-income, community-dwelling older adults. OBJECTIVE To evaluate program feasibility and MH outcomes among community-dwelling older adults randomized to 1 of 2 treatment arms of varying intensity of evidence-based, collaborative MH care management services (ie, the Supporting Seniors Receiving Treatment and Intervention [SUSTAIN] program) that provide standardized, measurement-based, software-aided MH assessment and symptom monitoring and connection to community resources via telephone. DESIGN, SETTING, AND PARTICIPANTS Trial participants were 1018 older, community-dwelling, low-income adults prescribed an antidepressant or anxiolytic by a primary care or non-MH professional and experiencing clinically significant MH symptoms at intake. The participant subsample was drawn from a larger parent sample of older adults enrolled in the SUSTAIN program. Individuals were randomized to receive MH symptom monitoring alone (hereafter monitoring alone) or MH symptom monitoring plus care management (hereafter care management) provided by an MH professional. Baseline characteristics were examined, and changes in clinical MH outcomes were evaluated at 3-month and 6-month follow-up. The study dates were August 5, 2010, to May 5, 2014. INTERVENTIONS Monitoring alone or care management delivered by an MH professional. MAIN OUTCOMES AND MEASURES Overall MH functioning (primary) and depressive and anxiety symptoms. RESULTS A total of 509 participants were randomized to the monitoring alone group and 509 to the care management group; 377 and 401 completed Ն2 research assessments in the monitoring alone and case management groups, respectively. Compared with those randomized to monitoring alone, individuals randomized to care management showed greater improvements in the 3 domains of MH functioning (β [SE], 0.

Objectives. Various aspects of one's social ties are thought to influence the onset, progression, and course of disability in older adulthood. Although the longitudinal course of social ties and physical disability is likely to be marked by fluctuations over time and intraindividual variation, few studies have explored how patterns of change in positive and negative social exchanges relate to patterns of change in disability across time. The current study, therefore, examined the extent to which distinct longitudinal trajectories of positive and negative exchanges were associated with patterns of physical disability.Methods. We followed a sample of 482 community-dwelling older adults with little to no disability at baseline for 2 years.Results. Results identified multiple, distinct trajectory groups for positive and negative exchanges and disability. Latent class growth analyses revealed that individuals with chronically high or low positive exchanges were likely to experience low and increasing levels of disability. With respect to negative exchanges, individuals with moderately increasing negative exchanges showed patterns of increasing disability and disability remission, whereas chronically low or absent negative exchanges were associated with low and increasing levels of disability.Discussion. Findings highlight the importance of evaluating multiple trajectories of change in older adults' social exchanges and disability.

Parkinson's disease (PD) significantly impacts both patients' and spouses' emotional and physical health. However, despite the importance of social relationships for wellbeing, few studies have examined relationship quality and their correlates in individuals with PD and their partners. Specifically, no known studies have examined the association between benefit finding, or the experience of personal growth and other positive changes in the face of a stressor, and perceived marital quality. To address these gaps in the field, 25 married couples participated in a cross-sectional, pilot study. Patients were veterans diagnosed with idiopathic PD receiving care at the Philadelphia VA Medical Center. Each patient and spouse independently completed self-reported measures of sociodemographics, physical and mental wellbeing, caregiver burden, marital quality, and perceived benefits associated with having PD. Actor-partner interdependence models revealed that, after adjusting for covariates, greater perceived benefits from either having PD or living with a spouse with PD was associated with greater marital quality, both for that individual and their partner. Thus, perceiving positive consequences, such as personal growth, as a result of personally having PD or living with a spouse with PD is related to greater marital quality for both members of the marital dyad. Findings may inform individual and couples-based interventions that address the value of benefit finding and incorporate other techniques of positive reappraisal.
