Amount and intensity of physical activity, fitness, and serum lipids in pre-menopausal women.

The aim of the study was to determine the association between the amount and the intensity of physical activity (PA) and lipid profile and fitness in pre-menopausal women. A cross-sectional study was conducted, sampling was stratified according to two age groups and two levels of PA, as assessed by the Minnesota Leisure Time PA Questionnaire. Serum lipid profile and sex hormones were measured.

Sport practice and the risk of lone atrial fibrillation: a case-control study.

Background: Lone atrial fibrillation (LAF) is characterized by the presence of atrial fibrillation in the absence of structural heart disease or other identifiable cause of arrhythmia. In a recent study, we reported sport practice to be more frequent in LAF patients than in the general population. The aim of the study was to determine the association between sport practice and the prevalence of LAF in men.

Response of oxidative stress biomarkers to a 16-week aerobic physical activity program, and to acute physical activity, in healthy young men and women.

Physical activity (PA) is associated with a reduced risk of coronary heart disease, and may favorably modify the antioxidant-prooxidant balance. This study assessed the effects of aerobic PA training on antioxidant enzyme activity, oxidized LDL concentration, and LDL resistance to oxidation, as well as the effect of acute PA on antioxidant enzyme activity before and after the training period. Seventeen sedentary healthy young men and women were recruited for 16 weeks of training.

[Intrahepatic portal venous hypoplasia in Alagille's syndrome].

One new case of arteriohepatic dysplasia (Alagille's syndrome) is reported. The case showed signs of progressive portal hypertension with the liver biopsy revealing evidence of hypoplasia of the intrahepatic portal venous branches without evident cirrhosis, next to the characteristic paucity of intrahepatic bile ducts. This venous abnormality might be responsible for the unfavourable outcome observed in some cases with Alagille's syndrome and corresponds to a severe form of the disease.

[Vertical transmission of hepatitis B from a maternal HBeAg-negative and antiHBe-positive carrier].

A case of vertical transmission of hepatitis B in an infant, born to a carrier mother HBeAg negative an anti Hbe positive, who developed and hyper-acute hepatitis, is presented. It was thought until quite recently, that perinatal hepatitis B was only transmitted by those HBsAg carrier mothers with positive HBeAg and negative anti Hbe. The infant here presented shows that all HBsAg carrier mothers are potential transmitters, and that all their newborns must have immunoprophylaxis.
