Folie à deux - Thrombosis and Infections Abstract: Although infections are not represented in the Revised Geneva or Wells score, they increase the risk of venous thromboembolism (VTE) similarly to the known risk factors (immobilization, major surgery, active neoplasia). This increased risk of VTE can persist for six to twelve months after infection; moreover, the more severe the infection, the higher the risk of VTE may be. In addition to VTEs, infections can promote arterial thromboembolism. For example, 20% of pneumonias are accompanied by an acute cardiovascular event (acute coronary syndrome, heart failure, atrial fibrillation). In the case of infection-associated atrial fibrillation, the CHA2DS2 VASc score remains an appropriate guide for the indication of anticoagulation.

The Role of the Electrocardiogram (ECG) In the Screening and Prevention of Sudden Cardiac Death in Sports Abstract: Athletes carry a higher risk for sports-related sudden cardiac death compared to the general population. The majority of these athletes suffer from an undiagnosed heart disease. Since physical activity is an essential trigger for sudden cardiac death in individuals with undiagnosed, usually hereditary, heart disease, sports can lead to sudden cardiac death in these athletes. Different heart diseases lead to sudden cardiac death at different ages during sports. The electrocardiogram (ECG) is an important screening tool to identify individuals of all ages with heart disease that are associated with sports-related sudden cardiac death. These individuals can then be treated and lives can be saved.

The Impact of Nutrition on Muscle Health in Older Individuals Abstract: The age-related change in the importance of nutrition for muscle health starts at the age of 50. Considering its effects on the mobility and physical independence of older people, the aging of the musculoskeletal system represents one of the greatest public health challenges and tasks for a demographically aging Switzerland. In particular sarcopenia, a pathological decrease in muscle strength, muscle mass and muscle function beyond the physiological age-related changes, correlates with a significantly increased risk of falls as well as increasing morbidity and mortality. Common chronic diseases related to old age not only promote additional muscle loss but also frailty, leading to an additional decline of the quality of life. General practitioners play a crucial role in the initial assessment of changing life circumstances and activity profiles of older people. Thanks to their medical care over many years they are able to identify functional impairments of their aging patients at an early stage and address them in time. This is important because the combination of a high-protein diet and exercise may be extremely effective for improving muscle health and function. Eating more proteins (taking into account the newly revised and increased daily protein requirement for healthy seniors of 1,0-1,2g/kg body weight (bw)) can significantly slow down age-related muscle loss. Depending on age and comorbidities, the daily protein requirement might be even higher (1,5 to 2,0g/kg bw). According to current studies, a minimal protein amount of 25-35g per main dish is recommended for optimal muscle growth stimulation among older individiuals. Thanks to their highly potent boosting power on myofibrillar protein synthesis rates the amino acid L-leucine and L-leucine-rich foods play an important role in elderly people's diet.

Hormonal Causes for Excessive Sweating Abstract: Excessive sweating is a frequent symptom in the general practice, but quite a few patients report their sweating problems only when explicitly asked. The differentiation into night sweats on the one hand and general sweating on the other hand can give us first diagnostic hints. Based on their frequency, night sweats should also trigger questions about panic attacks or sleeping disorders. The most frequent hormonal causes for excessive sweating are the menopause and hyperthyroidism. Hypogonadism in the aging male is a rather rare cause for excessive sweating and must be associated with sexual problems and a repeatedly low morning testosterone. This article provides an overview about the most frequent hormonal causes of excessive sweating and the diagnostic approach.

CME: Outpatient Management of Patients with Liver Cirrhosis Abstract: Many causes of cirrhosis are modifiable. Therefore, etiologic clarification is mandatory. After diagnosis, the underlying disease must be treated and patients advised as to alcohol abstinence, smoking cessation, healthy diet, vaccinations and physical exercise. Gastroscopic screening for oesophageal varices is recommended. Patients with cirrhosis should undergo surveillance for hepatocellular carcinoma (biannual sonography and alpha-fetoprotein assessment). Following a first complication (e.g., variceal haemorrhage, ascites, encephalopathy) or deterioration of liver function, listing for liver transplantation should be evaluated. Control intervals should be individualized according to disease severity and previous decompensations. Many complications (e.g., bleeding, spontaneous bacterial peritonitis, acute renal failure due to NSAIDs or diuretics) have insidious onsets but may rapidly lead to multiple organ failure. Rapid diagnostics are recommended if patients show clinical, mental or lab deterioration.

Electrical Accidents Abstract: When persons seek medical help after an electrical injury, physicians have to inquire on the type (AC/DC) and strength of current (>1000V is considered "high voltage") as well as the exact circumstances (loss of consciousness, falls) of the accident. In the advent of high-voltage accidents, loss of consciousness, arrhythmias, abnormal ECG or elevated troponin levels, in-hospital rhythm monitoring is warranted. In all other cases, the type of extra cardiac injury primarily directs the management. Superficial skin marks may disguise more extensive thermal injuries of inner organs.
