CONTEXT Euthyroid women with autoimmune thyroid disease show impairment of thyroid function during gestation and seem to suffer from a higher rate of obstetrical complications. OBJECTIVE We sought to determine whether these women suffer from a higher rate of obstetrical complications and whether levothyroxine (LT(4)) treatment exerts beneficial effects.(More)
CONTEXT Pregnant women who are positive for thyroid peroxidase antibodies [TPOAb(+)] are prone to develop postpartum thyroid dysfunction (PPTD) and permanent hypothyroidism. Selenium (Se) decreases thyroid inflammatory activity in patients with autoimmune thyroiditis. OBJECTIVE We examined whether Se supplementation, during and after pregnancy, influences(More)
Conventional algorithms for regulating insulin infusion rates in those critical diabetic patients submitted to parenteral glucose and insulin infusions do not allow to approach near normal blood glucose (BG) levels since traditional control systems are not fully effective in complex nonlinear systems as BG control is. Thus, we applied fuzzy logic principles(More)
BACKGROUND Infertile women positive for thyroid antibodies suffer from a poor pregnancy/delivery outcome, although conflicting data have been published. Our objective was to investigate if levothyroxine (LT4) exerts any effect on pregnancy and/or delivery rates in thyroid peroxidase antibody (TPOAb)-positive (+) women undergoing assisted reproductive(More)
UNLABELLED Thyroid dysfunction and the presence of thyroid antibodies increase the risk of infertility and miscarriage. The aim of the present study was to assess if patients with autoimmune thyroid disease undergoing assisted reproduction technologies (ART) are afflicted by poor pregnancy and/or delivery rate and if the outcome is conditioned by pre-ART(More)
BACKGROUND/AIMS A delay in recognizing and treating an inflamed gallbladder may increase the risk of a necrotic evolution and represent a critical factor affecting the progression of the inflammatory process. Aim of the study is to assess the therapeutic attitude in patients with histologically proved gangrenous cholecystitis, to find out whether it could(More)
The effect of alcoholism or acute alcohol ingestion on carbohydrate metabolism is not clear. The metabolic features of alcoholics cannot be easily achieved in normal men submitted to investigations concerning the effects of alcohol on glucose tolerance. Undernutrition and/or malnutrition characterize the eating behavior of alcoholics. It is also well-known(More)
The renal extraction of insulin and glucagon was studied in dogs subjected to temporary interruption of vascular perfusion of the liver. This was performed using hepatic artery occlusion after functional end-to-side portacaval anastomosis. The renal extraction of immunoreactive insulin and glucagon was studied by means of renal arterial-venous concentration(More)
The aim of the present study was to evaluate the impact of hyperthyroidism on the cardiovascular system by separately analyzing the sympathetic and parasympathetic influences on heart rate. Heart rate variability was evaluated by autoregressive power spectral analysis. This method allows a reliable quantification of the low frequency (LF) and high frequency(More)
We evaluated the effects of gestational weight gain on neonatal birthweight women in whom gestational diabetes mellitus (GDM) was diagnosed after the 32nd week of gestation. The prevalence of macrosomia, the birthweight differences from 50th percentile value of a reference population, and the relationships among plasma glucose values during oral glucose(More)
