Abstract Objective: Multiple interventions are available to reduce excess body weight in children. We appraised the quality of evidence supporting each intervention and assessed the effectiveness on different obesity-related outcomes. Methods: We conducted a systematic search for systematic reviews of randomized controlled trials evaluating pediatric obesity interventions applied for ≥6 months. We assessed the quality of evidence for each intervention using GRADE (Grading of Recommendation, Assessment, Development, and Evaluation) approach. Results: From 16 systematic reviews, we identified 133 eligible randomized controlled trials. Physical activity interventions reduced systolic blood pressure and fasting glucose (low to moderate quality of evidence). Dietary interventions with low-carbohydrate diets had a similar effect to low-fat diets in terms of body mass index (BMI) reduction (moderate quality of evidence). Educational interventions reduced waist circumference, BMI, and diastolic blood pressure (low quality of evidence). Pharmacological interventions reduced BMI (metformin, sibutramine, orlistat) and waist circumference (sibutramine, orlistat) and increased high-density lipoprotein cholesterol (sibutramine) but also raised systolic and diastolic blood pressure (sibutramine). Surgical interventions (laparoscopic adjustable gastric banding, Roux-en-Y gastric bypass, sleeve gastrectomy) resulted in the largest BMI reduction (moderate quality of evidence). Combined interventions consisting of dietary modification, physical activity, behavioral therapy, and education significantly reduced systolic and diastolic blood pressure, BMI, and triglycerides. Combined parent–child interventions and parent-only interventions had similar effects on BMI (low quality of evidence). Conclusions: Several childhood obesity interventions are effective in improving metabolic and anthropometric measures. A comprehensive multicomponent intervention, however, appears to have the best overall outcomes.

AbstractCosponsoring Associations:The European Society of Endocrinology and the Pediatric Endocrine Society. This guideline was funded by the Endocrine Society.Objective:To formulate clinical practice guidelines for the assessment, treatment, and prevention of pediatric obesity.Participants:The participants include an Endocrine Society–appointed Task Force of 6 experts, a methodologist, and a medical writer.Evidence:This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation approach to describe the strength of recommendations and the quality of evidence. The Task Force commissioned 2 systematic reviews and used the best available evidence from other published systematic reviews and individual studies.Consensus Process:One group meeting, several conference calls, and e-mail communications enabled consensus. Endocrine Society committees and members and co-sponsoring organizations reviewed and commented on preliminary drafts of this guideline.Conclusion:Pediatric obesity remains an ongoing serious international health concern affecting ∼17% of US children and adolescents, threatening their adult health and longevity. Pediatric obesity has its basis in genetic susceptibilities influenced by a permissive environment starting in utero and extending through childhood and adolescence. Endocrine etiologies for obesity are rare and usually are accompanied by attenuated growth patterns. Pediatric comorbidities are common and long-term health complications often result; screening for comorbidities of obesity should be applied in a hierarchal, logical manner for early identification before more serious complications result. Genetic screening for rare syndromes is indicated only in the presence of specific historical or physical features. The psychological toll of pediatric obesity on the individual and family necessitates screening for mental health issues and counseling as indicated. The prevention of pediatric obesity by promoting healthful diet, activity, and environment should be a primary goal, as achieving effective, long-lasting results with lifestyle modification once obesity occurs is difficult. Although some behavioral and pharmacotherapy studies report modest success, additional research into accessible and effective methods for preventing and treating pediatric obesity is needed. The use of weight loss medications during childhood and adolescence should be restricted to clinical trials. Increasing evidence demonstrates the effectiveness of bariatric surgery in the most seriously affected mature teenagers who have failed lifestyle modification, but the use of surgery requires experienced teams with resources for long-term follow-up. Adolescents undergoing lifestyle therapy, medication regimens, or bariatric surgery for obesity will need cohesive planning to help them effectively transition to adult care, with continued necessary monitoring, support, and intervention. Transition programs for obesity are an uncharted area requiring further research for efficacy. Despite a significant increase in research on pediatric obesity since the initial publication of these guidelines 8 years ago, further study is needed of the genetic and biological factors that increase the risk of weight gain and influence the response to therapeutic interventions. Also needed are more studies to better understand the genetic and biological factors that cause an obese individual to manifest one comorbidity vs another or to be free of comorbidities. Furthermore, continued investigation into the most effective methods of preventing and treating obesity and into methods for changing environmental and economic factors that will lead to worldwide cultural changes in diet and activity should be priorities. Particular attention to determining ways to effect systemic changes in food environments and total daily mobility, as well as methods for sustaining healthy body mass index changes, is of importance.

AbstractBackgroundThe acquisition of intravenous (IV) access in the actively convulsing patient is difficult. This often delays the administration of the IV benzodiazepine (BDZ) necessary for seizure cessation. Delays in seizure cessation are associated with increased pharmacoresistance, increased risk of neuronal injury, worse patient outcomes, and increased morbidity.ObjectiveThe objective was to assess whether the delay imposed by IV access acquisition is justified by improved outcomes. We compared IV versus non‐IV BDZ efficacy in the real world with regard to failure rates (primary outcome), interval to seizure control, and observed complications (secondary outcomes).MethodsA systematic review was performed using Medline, Embase, and the Cochrane Library. All studies published or in press from the inception of the respective database to July 2016 were included. Only randomized and quasi‐randomized controlled trials directly comparing IV to non‐IV (buccal, rectal, intranasal, or intramuscular) BDZ were included.ResultsOur search strategy retrieved 2,604 citations for review. A total of 11 studies were finally included in qualitative synthesis and 10 in quantitative analysis. Only one was of high quality. For treatment failure, non‐IV BDZ was superior to IV BDZ (odd ratio [OR] = 0.72; 95% confidence interval [CI] = 0.56–0.92). However, no significant difference was found between the two treatments in the pediatric subgroup (OR = 1.16; 95% CI = 0.74–1.81). Non‐IV BDZ was administered faster than IV BDZ and therefore controlled seizures faster (mean difference = 3.41 minutes; 95% CI = 1.69–5.13 minutes) despite a longer interval between drug administration and seizure cessation (mean difference = 0.74 minutes; 95% CI = 0.52–0.95 minutes). Respiratory complications requiring intervention were similar between non‐IV BDZ and IV BDZ, regardless of administration route (risk difference = 0.00; 95% CI = –0.02 to 0.01).ConclusionNon‐IV BDZ, compared to IV BDZ, terminate seizures faster and have a superior efficacy and side effect profile. Higher‐quality studies and further evaluation in different age groups are warranted.

AbstractObjectivesWe performed a systematic review and meta‐regression analysis of randomized control trials to investigate the association between response to initial treatment and survival outcomes in patients with newly diagnosed multiple myeloma (MM).MethodsResponse outcomes included complete response (CR) and the combined outcome of CR or very good partial response (VGPR), while survival outcomes were overall survival (OS) and progression‐free survival (PFS). We used random‐effect meta‐regression models and conducted sensitivity analyses based on definition of CR and study quality.ResultsSeventy‐two trials were included in the systematic review, 63 of which contributed data in meta‐regression analyses. There was no association between OS and CR in patients without autologous stem cell transplant (ASCT) (regression coefficient: .02, 95% confidence interval [CI] −0.06, 0.10), in patients undergoing ASCT (−.11, 95% CI −0.44, 0.22) and in trials comparing ASCT with non‐ASCT patients (.04, 95% CI −0.29, 0.38). Similarly, OS did not correlate with the combined metric of CR or VGPR, and no association was evident between response outcomes and PFS. Sensitivity analyses yielded similar results.ConclusionsThis meta‐regression analysis suggests that there is no association between conventional response outcomes and survival in patients with newly diagnosed MM.
