Weight Loss Maintenance - Article
ABSTRACT: Successful long-term weight loss maintenance can be achieved by various means. A combination of dietary and physical activity interventions, along with one or more behavioral approaches, has proven successful in some persons, as documented by the National Weight Control Registry, but is limited by adherence to a consistent weight loss regimen. Successful approaches to weight loss maintenance include consulting with a physician, nutritionist, or another support source; adhering to a stable diet with a limited variety of food; monitoring weight; eating breakfast; and exercising regularly. Long-term pharmacologic treatments for weight loss maintenance have been studied and were found to have modest success, with some weight regain typically reported. Sibutramine and orlistat are the two medications approved by the U.S. Food and Drug Administration with the potential to help patients achieve long-term weight loss maintenance. Bariatric surgery is another modality for accomplishing successful long-term weight loss maintenance in patients with morbid or complicated obesity. Its success is due in large part to better weight loss outcomes, more successful long-term weight loss maintenance, and remission of comorbid medical conditions.

Treatment of Knee Osteoarthritis - Article
ABSTRACT: Knee osteoarthritis is a common disabling condition that affects more than one-third of persons older than 65 years. Exercise, weight loss, physical therapy, intra-articular corticosteroid injections, and the use of nonsteroidal anti-inflammatory drugs and braces or heel wedges decrease pain and improve function. Acetaminophen, glucosamine, ginger, S-adenosylmethionine (SAM-e), capsaicin cream, topical nonsteroidal anti-inflammatory drugs, acupuncture, and tai chi may offer some benefit. Tramadol has a poor trade-off between risks and benefits and is not routinely recommended. Opioids are being used more often in patients with moderate to severe pain or diminished quality of life, but patients receiving these drugs must be carefully selected and monitored because of the inherent adverse effects. Intra-articular corticosteroid injections are effective, but evidence for injection of hyaluronic acid is mixed. Arthroscopic surgery has been shown to have no benefit in knee osteoarthritis. Total joint arthroplasty of the knee should be considered when conservative symptomatic management is ineffective.
ABSTRACT: Bariatric surgery procedures, including laparoscopic adjustable gastric banding, laparoscopic sleeve gastrectomy, and Roux-en-Y gastric bypass, result in an average weight loss of 50 percent of excess body weight. Remission of diabetes mellitus occurs in approximately 80 percent of patients after Roux-en-Y gastric bypass. Other obesity-related comorbidities are greatly reduced, and health-related quality of life improves. The Obesity Surgery Mortality Risk Score can help identify patients with increased mortality risk from bariatric surgery. Complications and adverse effects are lowest with laparoscopic surgery, and vary by procedure and presurgical risk. The Roux-en-Y procedure carries an increased risk of malabsorption sequelae, which can be minimized with standard nutritional supplementation. Outcomes are also influenced by the experience of the surgeon and surgical facility. Overall, these procedures have a mortality risk of less than 0.5 percent. Although there have been no long-term randomized controlled trials, existing studies show that bariatric surgery has a beneficial effect on mortality. The family physician is well positioned to care for obese patients by discussing surgery as an option for long-term weight loss. Counseling about the procedure options, risks and benefits of surgery, and the potential reduction in comorbid conditions is important. Patient selection, presurgical risk reduction, and postsurgical medical management, with nutrition and exercise support, are valuable roles for the family physician.
ABSTRACT: Nonalcoholic fatty liver disease is characterized by excessive fat accumulation in the liver (hepatic steatosis). Nonalcoholic steatohepatitis is characterized by steatosis, liver cell injury, and inflammation. The mechanism of nonalcoholic fatty liver disease is unknown but involves the development of insulin resistance, steatosis, inflammatory cytokines, and oxidative stress. Nonalcoholic fatty liver disease is associated with physical inactivity, obesity, and metabolic syndrome. Screening is not recommended in the general population. The diagnosis is usually made after an incidental discovery of unexplained elevation of liver enzyme levels or when steatosis is noted on imaging (e.g., ultrasonography). Patients are often asymptomatic and the physical examination is often unremarkable. No single laboratory test is diagnostic, but tests of liver function, tests for metabolic syndrome, and tests to exclude other causes of abnormal liver enzyme levels are routinely performed. Imaging studies, such as ultrasonography, computed tomography, and magnetic resonance imaging, can assess hepatic fat, measure liver and spleen size, and exclude other diseases. Liver biopsy remains the criterion standard for the diagnosis of nonalcoholic steatohepatitis. Noninvasive tests are available and may reduce the need for liver biopsy. A healthy diet, weight loss, and exercise are first-line therapeutic measures to reduce insulin resistance. There is insufficient evidence to support bariatric surgery, metformin, thiazolidinediones, bile acids, or antioxidant supplements for the treatment of nonalcoholic fatty liver disease. The long-term prognosis is not associated with an increased risk of all-cause mortality, cardiovascular disease, cancer, or liver disease.
ABSTRACT: Unintentional weight loss in persons older than 65 years is associated with increased morbidity and mortality. The most common etiologies are malignancy, nonmalignant gastrointestinal disease, and psychiatric conditions. Overall, nonmalignant diseases are more common causes of unintentional weight loss in this population than malignancy. Medication use and polypharmacy can interfere with taste or cause nausea and should not be overlooked. Social factors may contribute to unintentional weight loss. A readily identifiable cause is not found in 16% to 28% of cases. Recommended tests include a complete blood count, basic metabolic panel, liver function tests, thyroid function tests, C-reactive protein levels, erythrocyte sedimentation rate, glucose measurement, lactate dehydrogenase measurement, and urinalysis. Chest radiography and fecal occult blood testing should be performed. Abdominal ultrasonography may also be considered. When baseline evaluation is unremarkable, a three- to six-month observation period is justified. Treatment focuses on the underlying cause. Nutritional supplements and flavor enhancers, and dietary modification that takes into account patient preferences and chewing or swallowing disabilities may be considered. Appetite stimulants may increase weight but have serious adverse effects and no evidence of decreased mortality.
