Selected Cardiovascular Risk Markers in Vegetarians and Subjects of General Population.

Objective: Besides genetic factors there are environmental effects including nutritional habits which can influence the risk of age-related diseases. The aim of the study was to assess the age dependence of selected cardiovascular risk markers in two groups of subjects with different nutritional pattern.

Methods: In 470 long-term vegetarians and 478 subjects of general population the following indicators were measured: total cholesterol, HDL-cholesterol, triacylglycerol, glucose, insulin concentrations, LDL-cholesterol, atherogenic index and insulin resistance IR(HOMA) were also calculated in studied subjects.

Chemotherapy for acute myeloid leukemias with cytosine arabinoside, daunorubicin, etoposide, and mitoxantrone may cause permanent oligoasthenozoospermia or amenorrhea in middle-aged patients.

The aim was to follow-up gonadal functions in long-term survivors of acute myeloid leukemias (AML) after intensive chemotherapy based on high-doses of cytosine arabinoside (Ara-C) and anthracyclines in the study UHKT-911. Adult patients were treated with at least 3 cycles of chemotherapy including 1-3 courses of Ara-C 10 x 2000 mg/m2/12 h and daunorubicin (DNR) 2 x 45 mg/m2/d. Spermiologic examinations were performed in 7 men by the classic microscopic method and results were evaluated according to the WHOcriteria.
