AIM To calibrate eight-polar bioelectrical impedance analysis (BIA) against dual-energy X-ray absorptiometry (DXA) for the assessment of total and appendicular body composition in healthy adults. RESEARCH DESIGN A cross-sectional study was carried out. SUBJECTS Sixty-eight females and 42 males aged 21-82 years participated in the study. METHODS(More)
BACKGROUND Idiopathic cerebral vein thrombosis (iCVT) represents approximately 30% of the cases of cerebral vein thrombosis (CVT). New, inherited - factor V Leiden (FVL) and prothrombin gene mutation (PTHRA20210) - and inherited/acquired - hyperhomocysteinemia (HHcy) - prothrombotic conditions have been detected recently. METHODS We assessed fasting(More)
BACKGROUND Summer 2003 witnessed an excess in heat-related mortality in the elderly population. The Argento Project was planned to define risk factors for heat-related death in Modena, Italy, during the hottest month of 2003 (August). METHODS We performed a retrospective, case-control study of a cohort of 394 older persons living in Modena, 197 dead(More)
Apoptosis plays a central role in the homeostasis of the immune system. During aging, there is an altered regulation of pivotal molecules that are responsible for the regulation of this type of cell death, such as those of the Fas/FasL system. Understanding the regulation of these genes can help to clarify, at least in part, the age-related changes that(More)
OBJECTIVES To test the applicability and safety of a standardized diagnostic algorithm in geriatric departments and to define the prevalence of different causes of syncope in older patients. DESIGN Multicenter cross-sectional observational study. SETTING In-hospital geriatric acute care departments and outpatient clinics. PARTICIPANTS Two hundred(More)
The morphology of red blood cells was studied in 30 patients with severe liver cirrhosis, in 10 patients with extrahepatic jaundice, and in 10 control subjects. In all the patients with extrahepatic jaundice more than 30% of red blood cells were target cells with increased resistance to osmotic lysis. In 12 patients with liver cirrhosis more than 30% of red(More)
To evaluate the importance of serum anticholinergic activity (SAA) in elderly patients who developed delirium following hospital admission, we performed a cross-sectional study with consecutively referred inpatients in a university geriatric medical ward. Sixty-one patients aged 66 to 95 years (mean age: 79.2+/-11.6; 54% females) were recruited. Delirium(More)
Using compressed discs and microcrystals of cholesterol monohydrate, we evaluated the mechanisms and kinetics of dissolution in conjugated bile salt-lecithin solutions. In stirred conjugated ursodeoxycholate-lecithin and cheno-deoxycholate-lecithin solutions, dissolution of 10,000-psi discs was micellar and linear with time for 10 hours. The dissolution(More)
OBJECTIVE To evaluate the accuracy of body mass index (BMI) as a predictor of body fat in elderly women. RESEARCH METHODS AND PROCEDURES A total of 1423 women aged 67 +/- 5 (mean +/- SD, range: 60 to 88) years were consecutively enrolled into the study. Fat mass (FM) was measured using DXA. RESULTS BMI explained 72.9% of FM variance (p < 0.0001), with a(More)
The morphological and functional alterations of the smooth endoplasmic reticulum of the liver cell related to biliary stasis have brought attention to drug biotransformation during cholestasis. The metabolism of meprobamate, pentobarbital and tolbutamide was assessed in subjects with intrahepatic recurrent cholestasis (3), cholestatic hepatitis (6),(More)
