Importance Suicide is a leading cause of death among young people and an escalating public health crisis. Objective To assess the effectiveness and harms of available treatments for suicidal thoughts and behaviors among youths at heightened risk for suicide. Evidence Review A systematic review was conducted searching databases including MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Scopus, and various gray literature sources from January 1, 2000, to September 26, 2024. We included randomized clinical trials, comparative observational studies, and before-after studies of psychosocial interventions, pharmacologic interventions, neurotherapeutics, emerging therapies, and combination therapies. Eligible patients were youths (aged 5-24 years) with heightened risk for suicide, adolescents from racial and ethnic minority groups known to be at increased risk of suicide, or those exposed to crime or violence. Pairs of independent reviewers selected and appraised studies. Findings This review included 65 studies (33 randomized clinical trials, 13 comparative observational studies, and 19 before-after studies) reporting on 14 534 patients (median age, 15.1 years; 75.1% female patients). Psychosocial interventions comprised psychotherapy interventions (33 studies; cognitive behavioral therapy, dialectical behavioral therapy, collaborative assessment and management of suicidality, dynamic deconstructive psychotherapy, attachment-based family therapy, and family-focused therapy), acute (ie, 1-4 sessions or contacts) psychosocial interventions (19 studies; safety planning, family-based crisis management, motivational interviewing crisis interventions, continuity of care after crisis, and brief adjunctive treatments), and school- or community-based psychosocial interventions (13 studies; social network interventions, school-based skills interventions, suicide awareness or gatekeeper programs, and community-based, culturally tailored adjunct programs). Dialectical behavior therapy showed moderate strength of evidence for reducing suicidal ideation. Other categories of psychosocial treatments showed insufficient to low strength of evidence for reducing suicidal outcomes. None of the studies evaluated adverse events. The evidence base on pharmacologic treatment for youths at risk of suicide was largely nonexistent. Conclusions and Relevance This systematic review found that the current evidence on available interventions targeting youths at heightened risk of suicide is uncertain. Medication, neurotherapeutics, and emerging therapies remain unstudied among this population. The limited evidence base calls for the development of novel, developmentally and trauma-informed treatments, as well as multilevel interventions to target the increasing suicide risk among youths.
Translation of a family-based behavioral intervention for adolescent obesity using the RE-AIM framework and common steps from adaptation frameworks
Abstract Interventions for adolescent weight management that are ready to use in clinical settings are needed to address the obesity epidemic and improve the health and wellbeing of affected adolescents. This report describes the systematic process our team followed to adapt an evidence-based intervention (EBI) for adolescent weight management from its randomized control trial protocol to a package for delivery in a group-based telehealth format within a medical center. The EBI adaptation was clinician initiated, prompted by identified practice needs, and involved collaboration of the clinical team with the EBI developer. The process was guided by the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework and followed key steps for adapting EBIs to new contexts. RE-AIM-aligned adaptations included telehealth delivery and broader inclusion criteria, separate clinical and research evaluation batteries, adaptations to fit the clinical practice, practical fidelity checklists to guide and record session delivery, and continuous quality improvement processes aimed to facilitate program longevity and family engagement. The process culminated in a package of adapted intervention materials deemed by stakeholders as appropriate to the practice and congruent with the EBI model. This report provides a much-needed practical demonstration of the translation of an EBI for adolescent weight management from research protocol to group telehealth delivery in a medical center. Key lessons include the value of clinician-researcher collaboration, the breadth of resources needed to adapt EBIs for real-world delivery, and the importance of considering delivery context in implementation and evaluation decisions, including defining inclusion criteria, staffing, and outcomes assessments.
Weight Loss and Serum Lipids in Overweight and Obese Adults: A Systematic Review and Meta-Analysis
Abstract Background Excess adipose tissue is associated with an abnormal lipid profile that may improve with weight reduction. In this meta-analysis, we aimed to estimate the magnitude of change in lipid parameters associated with weight loss in adults who are overweight or obese. Methods We searched MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, and Scopus from 2013 to September, 2018. We included randomized controlled trials (RCTs) that evaluated interventions to treat adult obesity (lifestyle, pharmacologic and surgical) with follow-up of 6 months or more. Results We included 73 RCTs with moderate-to-low risk of bias, enrolling 32 496 patients (mean age, 48.1 years; weight, 101.6 kg; and body mass index [BMI], 36.3 kg/m2). Lifestyle interventions (diet, exercise, or both), pharmacotherapy, and bariatric surgery were associated with reduced triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) concentrations and increased high-density lipoprotein cholesterol (HDL-C) at 6 and 12 months. The following data are for changes in lipid parameters after 12 months of the intervention with 95% CI. Following lifestyle interventions, per 1 kg of weight lost, TGs were reduced by –4.0 mg/dL (95% CI, –5.24 to –2.77 mg/dL), LDL-C was reduced by –1.28 mg/dL (95% CI, –2.19 to –0.37 mg/dL), and HDL-C increased by 0.46 mg/dL (95% CI, 0.20 to 0.71 mg/dL). Following pharmacologic interventions, per 1 kg of weight lost, TGs were reduced by –1.25 mg/dL (95% CI, –2.94 to 0.43 mg/dL), LDL-C was reduced by –1.67 mg/dL (95% CI, –2.28 to –1.06 mg/dL), and HDL-C increased by 0.37 mg/dL (95% CI, 0.23 to 0.52 mg/dL). Following bariatric surgery, per 1 kg of weight lost, TGs were reduced by –2.47 mg/dL (95% CI, –3.14 to –1.80 mg/dL), LDL-C was reduced by –0.33 mg/dL (95% CI, –0.77 to 0.10 mg/dL), and HDL-C increased by 0.42 mg/dL (95% CI, 0.37 to 0.47 mg/dL). Low-carbohydrate diets resulted in reductions in TGs and increases in HDL-C, whereas low-fat diets resulted in reductions in TGs and LDL-C and increases in HDL-C. Results were consistent across malabsorptive and restrictive surgery. Conclusions Weight loss in adults is associated with statistically significant changes in serum lipids. The reported magnitude of improvement can help in setting expectations, inform shared decision making, and facilitate counseling.
Accuracy of Accelerometers for Measuring Physical Activity and Levels of Sedentary Behavior in Children: A Systematic Review
Objectives: This systematic review evaluated the accuracy of triaxial and omnidirectional accelerometers for measuring physical activity and sedentary behavior in children. Design: Systematic review of the literature. Methods: We comprehensively searched several databases for studies published from January 1996 through June 2018 that reported diagnostic accuracy measures in children and adolescents (age 3-18 years) and compared accelerometers with energy expenditure using indirect calorimetry. Results: We included 11 studies that enrolled 570 participants. All studies used indirect calorimetry as the reference standard. Across the studies, median sensitivity ranged from 46% to 96% and median specificity ranged from 71% to 96%. Median area under the curve ranged from 69% to 98%. Conclusions: Accuracy measures were greatest when detecting sedentary behavior and lowest when detecting light physical activity. Accuracy was higher when the accelerometer was placed on the hip compared with the wrist. The current evidence suggests that triaxial and omnidirectional accelerometers are accurate in measuring sedentary behavior and physical activity levels in children.
Identifying Opportunities for Advancing Weight Management in Primary Care
Objective: Much has been written about the patients’ perspective concerning weight management in health care. The purpose of this survey study was to assess perspectives of primary care providers (PCPs) and nurses toward patient weight management and identify possible areas of growth. Patients and Methods: We emailed a weight management–focused survey to 674 eligible participants (437 [64.8%] nurses and 237 [35.2%] PCPs) located in 5 outpatient primary care clinics. The survey focused on opportunities, practices, knowledge, confidence, attitudes, and beliefs. A total of 219 surveys were returned (137 [62.6%] from nurses and 82 [34.4%] from PCPs). Results: Among 219 responders, 85.8% were female and 93.6% were white non-Hispanic. In this study, PCPs and nurses believed obesity to be a major health problem. While PCPs felt more equipped than nurses to address weight management ( P < .001) and reported receiving more training than nurses (50.0% vs 17.6%, respectively), both felt the need for more training on obesity (73.8% and 79.4%, respectively). Although, PCPs also spent more patient contact time providing weight management services versus nurses ( P < .001), the opportunity/practices score was lower for PCPs than nurses (−0.35 ± 0.44 vs −0.17 ± 0.41, P < .001) with PCPs more likely to say they lacked the time to discuss weight and they worried it would cause a poor patient-PCP relationship. The knowledge/confidence score also differed significantly between the groups, with nurses feeling less equipped to deal with weight management issues than PCPs (−0.42 ± 0.43 vs −0.03 ± 0.55, P < .001). Neither group seemed very confident, with those in the PCP group only answering with an average score of neutral. Conclusion: By asking nurses and PCP general questions about experiences, attitudes, knowledge, and opinions concerning weight management in clinical care, this survey has identified areas for growth in obesity management. Both PCPs and nurses would benefit from additional educational training on weight management.
Direct free fatty acid storage in different sized adipocytes from the same depot
ObjectiveHuman adipocytes take up free fatty acids (FFA) directly from the circulation, even at times of high lipolytic activity. Whether these processes occurs simultaneously within the same cells or are partitioned between different cells, for example large and small cells, is unknown.MethodsThe direct FFA storage in subcutaneous fat in 13 adults were measured using a continuous infusion of [U‐13C]palmitate and a bolus of [1‐14C]palmitate followed 30 min later by abdominal and femoral adipose biopsies. The adipocytes were isolated by digestion procedures and separated into small, medium and large populations by differential floatation.ResultsPopulations of adipocytes were isolated that were statistically and clinically (∼3 fold different) in size. Adipocyte lipid SA was not different between small, medium and large cells, therefore, FFA storage per unit lipid was not different. However, FFA storage rates were significantly (two to four times) greater per cell in large than small cells (P < 0.005). In summary, relative to lipid content, FFA storage rates are not different in large and small adipocytes, however, large cells have greater storage rates per cell.ConclusionsThis suggests that the processes of FFA release and storage are taking place simultaneously in adipocytes.
