ABSTRACT: There are more than one half million cancer deaths in the United States each year, and one third of these deaths are attributed to suboptimal diet and physical activity practices. Maintaining a healthy weight, staying physically active throughout life, and consuming a healthy diet can substantially reduce the lifetime risk of developing cancer, as well as influence overall health and survival after a cancer diagnosis. The American Cancer Society's Nutrition and Physical Activity Guidelines serve as a source document for communication, policy, and community strategies to improve dietary and physical activity patterns among Americans. In 2006, they published updated guidelines for the primary prevention of cancer and guidelines for improving outcomes among cancer survivors through tertiary prevention. These two sets of guidelines have similar recommendations, including: achievement and maintenance of a healthy weight; regular physical activity of at least 30 minutes per day and at least five days per week; a plant-based diet high in fruits, vegetables, and whole grains and low in saturated fats and red meats; and moderate alcohol consumption, if at all. Physicians are encouraged to find teachable moments to impart appropriate nutrition, physical activity, and weight management guidance to their patients, and to support policies and programs that can improve these factors in the community to reduce cancer risk and improve outcomes after cancer.
ABSTRACT: Family physicians commonly care for patients with serious mental illness. Patients with psychotic and bipolar disorders have more comorbid medical conditions and higher mortality rates than patients without serious mental illness. Many medications prescribed for serious mental illness have significant metabolic and cardiovascular adverse effects. Patients treated with second-generation antipsychotics should receive preventive counseling and treatment for obesity, hyperglycemia, diabetes, and hyperlipidemia. First- and second-generation antipsychotics have been associated with QT prolongation. Many common medications can interact with antipsychotics, increasing the risk of cardiac arrhythmias and sudden death. Drug interactions can also lead to increased adverse effects, increased or decreased drug levels, toxicity, or treatment failure. Physicians should carefully consider the risks and benefits of second-generation antipsychotic medications, and patient care should be coordinated between primary care physicians and mental health professionals to prevent serious adverse effects.
ABSTRACT: Menopause is the permanent cessation of menstruation resulting from the loss of ovarian and follicular activity. It usually occurs when women reach their early 50s. Vasomotor symptoms and vaginal dryness are frequently reported during menopause. Estrogen is the most effective treatment for management of hot flashes and night sweats. Local estrogen is preferred for vulvovaginal symptoms because of its excellent therapeutic response. Bone mineral density screening should be performed in all women older than 65 years, and should begin sooner in women with additional risk factors for osteoporotic fractures. Adequate intake of calcium and vitamin D should be encouraged for all postmenopausal women to reduce bone loss. Coronary artery disease is the leading cause of death in women. Postmenopausal women should be counseled regarding lifestyle modification, including smoking cessation and regular physical activity. All women should receive periodic measurement of blood pressure and lipids. Appropriate pharmacotherapy should be initiated when indicated. Women should receive breast cancer screening every one to two years beginning at age 40, as well as colorectal cancer screening beginning at age 50. Women younger than 65 years who are sexually active and have a cervix should receive routine cervical cancer screening with Papanicolaou smear. Recommended immunizations for menopausal women include an annual influenza vaccine, a tetanus and diphtheria toxoid booster every 10 years, and a one-time pneumococcal vaccine after age 65 years.
ABSTRACT: Evidence-based guidelines for the treatment of type 2 diabetes mellitus focus on three areas: intensive lifestyle intervention that includes at least 150 minutes per week of physical activity, weight loss with an initial goal of 7 percent of baseline weight, and a low-fat, reduced-calorie diet; aggressive management of cardiovascular risk factors (i.e., hypertension, dyslipidemia, and microalbuminuria) with the use of aspirin, statins, and angiotensin-converting enzyme inhibitors; and normalization of blood glucose levels (hemoglobin A1C level less than 7 percent). Insulin resistance, decreased insulin secretion, and increased hepatic glucose output are the hallmarks of type 2 diabetes, and each class of medication targets one or more of these defects. Metformin, which decreases hepatic glucose output and sensitizes peripheral tissues to insulin, has been shown to decrease mortality rates in patients with type 2 diabetes and is considered a first-line agent. Other medications include sulfonylureas and nonsulfonylurea secretagogues, alpha glucosidase inhibitors, and thiazolidinediones. Insulin can be used acutely in patients newly diagnosed with type 2 diabetes to normalize blood glucose, or it can be added to a regimen of oral medication to improve glycemic control. Except in patients taking multiple insulin injections, home monitoring of blood glucose levels has questionable utility, especially in relatively well-controlled patients. Its use should be tailored to the needs of the individual patient.
Aerobic Activity for Cognitive Function - Cochrane for Clinicians
ABSTRACT: In a select group of persons, exercise can produce a spectrum of allergic symptoms ranging from an erythematous, irritating skin eruption to a life-threatening anaphylactic reaction. The differential diagnosis in persons with exercise-induced dermatologic and systemic symptoms should include exercise-induced anaphylaxis and cholinergic urticaria. Both are classified as physical allergies. Mast cell degranulation with the release of vasoactive substances appears to be an inciting factor for the production of symptoms in both cases. Exercise-induced anaphylaxis and cholinergic urticaria can be differentiated on the basis of urticarial morphology, reproducibility, progression to anaphylaxis and response to passive warming. Diagnosis is usually based on a thorough history and examination of the morphology of the lesions. Management of acute episodes of exercise-induced anaphylaxis includes cessation of exercise, administration of epinephrine and antihistamines, vascular support and airway maintenance. Long-term care may require modification of or abstinence from exercise, avoidance of co-precipitating factors and the prophylactic use of medications such as antihistamines and mast cell stabilizers.
ABSTRACT: Regular exercise provides a myriad of health benefits in older adults, including improvements in blood pressure, diabetes, lipid profile, osteoarthritis, osteoporosis, and neurocognitive function. Regular physical activity is also associated with decreased mortality and age-related morbidity in older adults. Despite this, up to 75 percent of older Americans are insufficiently active to achieve these health benefits. Few contraindications to exercise exist and almost all older persons can benefit from additional physical activity. The exercise prescription consists of three components: aerobic exercise, strength training, and balance and flexibility. Physicians play a key role in motivating older patients and advising them regarding their physical limitations and/or comorbidities. Motivating patients to begin exercise is best achieved by focusing on individual patient goals, concerns, and barriers to exercise. Strategies include the "stages of change" model, individualized behavioral therapy, and an active lifestyle. To increase long-term compliance, the exercise prescription should be straightforward, fun, and geared toward a patient's individual health needs, beliefs, and goals.
ABSTRACT: Several large clinical trials conducted over the past decade have shown that pharmacologic interventions can dramatically reduce the morbidity and mortality associated with heart failure. These trials have modified and enhanced the therapeutic paradigm for heart failure and extended treatment goals beyond limiting congestive symptoms of volume overload. Part II of this two-part article presents treatment recommendations for patients with left ventricular systolic dysfunction. The authors recommend that, if tolerated and not contraindicated, the following agents be used in patients with left ventricular systolic dysfunction: an angiotensin-converting enzyme inhibitor in all patients; a beta blocker in all patients except those who have symptoms at rest; and spironolactone in patients who have symptoms at rest or who have had such symptoms within the past six months. Diuretics and digoxin should be reserved, as needed, for symptomatic management of heart failure. Other treatments or treatment programs may be necessary in individual patients.
