TL;DR: Evidence for medication or behavioral treatment for BN is strong, for self-help is weak; for harms related to medication is strong but either weak or nonexistent for other interventions; and evidence for differential outcome by sociodemographic factors is nonexistent.
Abstract: Objective: The RTI International-University of North Carolina at Chapel Hill Evidence-based Practice Center (RTI-UNC EPC) systematically reviewed evidence on efficacy of treatment for anorexia nervosa (AN), harms associated with treatments, factors associated with treatment efficacy, and differential outcome by sociodemographic characteristics. Method: We searched six major databases for studies on the treatment of AN from 1980 to September 2005, in all languages against a priori inclusion/exclusion criteria focusing on eating, psychiatric or psychological, or biomarker outcomes. Results: Thirty-two treatment studies involved only medications, only behavioral interventions, and medication plus behavioral interventions for adults or adolescents. The literature on medication treatments and behavioral treatments for adults with AN is sparse and inconclusive. Cognitive behavioral therapy may reduce relapse risk for adults with AN after weight restoration, although its efficacy in the underweight state remains unknown. Variants of family therapy are efficacious in adolescents, but not in

TL;DR: The literature regarding treatment efficacy for BED is variable and future directions include the identification of optimal interventions that are associated with both sustained abstinence from binge eating and permanent weight loss.
Abstract: Objective: The Research Triangle Institute-University of North Carolina Evidence Based Practice Center (RTI-EPC) systematically reviewed evidence on efficacy of treatment for binge eating disorder (BED), harms associated with treatments, factors associated with treatment efficacy, and differential outcome by sociodemographic characteristics Method: We searched six major databases for studies on the treatment of BED published from 1980 to September, 2005, in all languages against a priori inclusion/exclusion criteria and focused on eating, psychiatric or psychological, or biomarker outcomes Results: Twenty-six studies, including medication-only, medication plus behavioral intervention, and behavioral intervention only designs, met inclusion criteria The strength of the evidence for medication and behavioral interventions was moderate, for self-help and other interventions was weak, for treatment-related harms was strong, for factors associated with efficacy of treatment was weak, and for differential outcome by sociodemographic factors was nonexistent Individual or group CBT reduces binge eating and improves abstinence rates for up to 4 months after treatment but does not lead to weight loss Medications may play a role in treating BED patients Conclusion: The literature regarding treatment efficacy for BED is variable Future directions include the identification of optimal interventions that are associated with both sustained abstinence from binge eating and permanent weight loss

TL;DR: Binge-eating disorder is associated with poorer psychological and physical well-being, including major depressive and other psychiatric disorders, and the use of cognitive behavioral therapy (CBT) and selective serotonin reuptake inhibitors, but they differ in content and timing.
Abstract: Background The best treatment options for binge-eating disorder are unclear. Purpose To summarize evidence about the benefits and harms of psychological and pharmacologic therapies for adults with binge-eating disorder. Data sources English-language publications in EMBASE, the Cochrane Library, Academic OneFile, CINAHL, and ClinicalTrials.gov through 18 November 2015, and in MEDLINE through 12 May 2016. Study selection 9 waitlist-controlled psychological trials and 25 placebo-controlled trials that evaluated pharmacologic (n = 19) or combination (n = 6) treatment. All were randomized trials with low or medium risk of bias. Data extraction 2 reviewers independently extracted trial data, assessed risk of bias, and graded strength of evidence. Data synthesis Therapist-led cognitive behavioral therapy, lisdexamfetamine, and second-generation antidepressants (SGAs) decreased binge-eating frequency and increased binge-eating abstinence (relative risk, 4.95 [95% CI, 3.06 to 8.00], 2.61 [CI, 2.04 to 3.33], and 1.67 [CI, 1.24 to 2.26], respectively). Lisdexamfetamine (mean difference [MD], -6.50 [CI, -8.82 to -4.18]) and SGAs (MD, -3.84 [CI, -6.55 to -1.13]) reduced binge-eating-related obsessions and compulsions, and SGAs reduced symptoms of depression (MD, -1.97 [CI, -3.67 to -0.28]). Headache, gastrointestinal upset, sleep disturbance, and sympathetic nervous system arousal occurred more frequently with lisdexamfetamine than placebo (relative risk range, 1.63 to 4.28). Other forms of cognitive behavioral therapy and topiramate also increased abstinence and reduced binge-eating frequency and related psychopathology. Topiramate reduced weight and increased sympathetic nervous system arousal, and lisdexamfetamine reduced weight and appetite. Limitations Most study participants were overweight or obese white women aged 20 to 40 years. Many treatments were examined only in single studies. Outcomes were measured inconsistently across trials and rarely assessed beyond end of treatment. Conclusion Cognitive behavioral therapy, lisdexamfetamine, SGAs, and topiramate reduced binge eating and related psychopathology, and lisdexamfetamine and topiramate reduced weight in adults with binge-eating disorder.

TL;DR: In this paper, the authors provided evidence-based recommendations for the prevention of future stroke among survivors of ischemic stroke or transient ischemi-chemic attack, including the control of risk factors, intervention for vascular obstruction, antithrombotic therapy for cardioembolism, and antiplatelet therapy for noncardioembolic stroke.
Abstract: The aim of this updated guideline is to provide comprehensive and timely evidence-based recommendations on the prevention of future stroke among survivors of ischemic stroke or transient ischemic attack. The guideline is addressed to all clinicians who manage secondary prevention for these patients. Evidence-based recommendations are provided for control of risk factors, intervention for vascular obstruction, antithrombotic therapy for cardioembolism, and antiplatelet therapy for noncardioembolic stroke. Recommendations are also provided for the prevention of recurrent stroke in a variety of specific circumstances, including aortic arch atherosclerosis, arterial dissection, patent foramen ovale, hyperhomocysteinemia, hypercoagulable states, antiphospholipid antibody syndrome, sickle cell disease, cerebral venous sinus thrombosis, and pregnancy. Special sections address use of antithrombotic and anticoagulation therapy after an intracranial hemorrhage and implementation of guidelines.

TL;DR: The related problem, loss-of-control (LOC) eating, describes recurrent binge-like eating behavior in individuals who cannot meet full criteria for BED such as post-bariatric surgery patients and children.
Abstract: Binge eating disorder (BED) is characterized by recurrent episodes of binge eating and, subsequently, significant psychological distress (e.g., shame, guilt). Recently recognized by the American Psychiatric Association (APA) as a distinct eating disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), BED is considered a significant public health problem independently and for its impact on obesity and diabetes. The related problem, loss-of-control (LOC) eating, describes recurrent binge-like eating behavior in individuals who cannot meet full criteria for BED such as post-bariatric surgery patients and children. LOC eating has detrimental psychological and physical health effects, including significant distress and symptoms of depression, as well as excess weight gain in children and suboptimal weight loss and weight regain in post-bariatric patients. Table 1 lists the diagnostic criteria for BED (as defined in the current DSM-5 and earlier, in the DSM, Fourth Edition [DSM-IV]) and frequently-used definitions of LOC eating.

TL;DR: Exercise remains a cornerstone therapy for the primary prevention, treatment, and control of HTN and angiotensin converting enzyme (ACE) inhibitors and calcium channel blockers are currently the drugs of choice for recreational exercisers and athletes who have HTN.
Abstract: SUMMARY Hypertension (HTN), one of the most common medical disorders, is associated with an increased incidence of all-cause and cardiovascular disease (CVD) mortality. Lifestyle modifications are advocated for the prevention, treatment, and control of HTN, with exercise being an integral component. Exercise programs that primarily involve endurance activity prevent the development of HTN and lower blood pressure (BP) in adults with normal BP and those with HTN. The BP lowering effects of exercise are most pronounced in people with HTN who engage in endurance exercise with BP decreasing approximately 5–7 mm Hg after an isolated exercise session (acute) or following exercise training (chronic). Moreover, BP is reduced for up to 22 h after an endurance exercise bout (e.g., postexercise hypotension), with the greatest decreases among those with the highest baseline BP. The proposed mechanisms for the BP lowering effects of exercise include neurohumoral, vascular, and structural adaptations. Decreases in catecholamines and total peripheral resistance, improved insulin sensitivity, and alterations in vasodilators and vasoconstrictors are some of the postulated explanations for the antihypertensive effects of exercise. Emerging data suggest genetic links to the BP reductions associated with acute and chronic endurance exercise. Nonetheless, definitive conclusions regarding the mechanisms for the BP reductions following endurance exercise cannot be made at this time. Individuals with controlled HTN and no CVD or renal complications may participate in an exercise program or competitive athletics, but should be evaluated, treated, and monitored closely. Preliminary peak or symptom-limited exercise testing may be warranted, especially for men over 45 and women over 55 yr planning a vigorous exercise program (i.e., 60% u VO2R, oxygen uptake reserve). In the interim, while formal evaluation and management are taking place, it is reasonable for the majority of patients to begin moderate intensity exercise training (40 –60% u VO2R) such as walking. When pharmacologic therapy is indicated in physically active people it should, ideally: a) lower BP at rest and during exertion; b) decrease total peripheral resistance; and, c) not adversely affect exercise capacity. For these reasons, angiotensin converting enzyme (ACE) inhibitors (or angiotensin II receptor blockers in case of ACE inhibitor intolerance) and calcium channel blockers are currently the drugs of choice for recreational exercisers and athletes who have HTN. Exercise remains a cornerstone therapy for the primary prevention, treatment, and control of HTN. The optimal training frequency, intensity, time, and type (FITT) need to be better defined to optimize the BP lowering capacities of exercise, particularly in children, women, older adults, and
