Practice Guideline[A recommended approach to evaluate cardiovascular risk and to prevent cardiovascular diseases and type 2 diabetes mellitus in women with polycystic ovary syndrome].
Polycystic ovary syndrome is one of the most common endocrinopathy in women of fertile age. It is commnoly accompanied by an increased occurence of cardiovascular risk factors. This association led to a consensus statement of Androgen Excess Society for screening of cardiovascular risk factors. We present the recommendations of Czech Endocrine and Czech Diabetological Societies for the screening and primary prevention of cardiovascular diseases and diabetes mellitus.

Early reperfusion is the treatment of choice for acute coronary syndrome. In the Czech Republic, reperfusion therapy is well accessible thanks to the network of 22 catheterization centres. ⋯ These steps than has to be accompanied by effective pharmacotherapy to prevent remodelling of the left ventricle, re-stenosis of the coronary artery, re-thrombosis and arrhythmias. Four drug groups provide the desired effects--renin-angiotensin-aldosterone system blockers, beta-blockers, antiplatelet agents and statins.

Review[Pathophysiological background for incretin therapy: is it capable of more than we think?].
Incretin-based therapy functions through the increase of endogenous glucagon-like peptide-1 (GLP-1) levels due to inhibition of dipeptidyl peptidase-4--an enzyme degrading GLP-1 (gliptins) or through the administration of drugs activating GLP-1 receptor (GLP-1 agonists). Both approaches increase insulin and decrease glucagon secretion leading to improved diabetes compensation. The advantages of gliptins include little side effects, body weight neutrality and potential protective effects on pancreatic beta cells. ⋯ Direct positive effects of incretin-based therapy on myocardial metabolism and function as well as its positive influence on endothelial dysfunction and neuroprotective effects are intensively studied. The possible indications for GLP-1 agonists could be in future further widened to obese patients with type 1 diabetes and obese patients without diabetes. The aim of this review is to summarize both metabolic and extrapancreatic effects of incretin-based therapies and to outline perspectives of potential wider use of this treatment approach.

Review[Infectious complications in patients after cardiac arrest undergoing therapeutic hypothermia].
Therapeutic hypothermia is currently recommended neuroprotective therapeutic measure for comatose patients after cardiac arrest. Hypothermia has been proven not only to affect the neurological outcomes but also the survival of patients after cardiac arrest. This communication summarizes the issue of early infectious complications in patients after cardiac arrest undergoing therapeutic hypothermia. ⋯ Furthermore, there are discussed limited diagnostic options of infectious complications. The significance of the usual symptoms of infections is reduced, as well as the value of laboratory markers such as procalcitonin and C-reactive protein. Finally, the possibility of antibiotic treatment and eventual antibiotic prophylaxis during therapeutic hypothermia in patients after cardiac arrest outside hospitals is mentioned.

Review[Residual risk of cardiovascular complications and its reduction with a combination of lipid lowering agents].
Most patients treated with statins die due to cardiovascular events. The risk of cardiovascular event during statin treatment is called residual risk. ⋯ Residual risk can be decreased by combination therapy statins with fibrates or statins with niacin; niacin can affect almost all lipids and lipoproteins that participate in residual risk. There are evidences from clinical trials that combinations statin with fibrates or statin with niacin are safe.
