Selenium status, fatty acids, vitamins A and E, and aging: the Nove Study.

To investigate the relationships between aging and selenium status, vitamins A and E, and plasma and erythrocyte fatty acids, we studied 105 healthy subjects (53 women, 52 men) living in Nove, a village near Vicenza (Veneto Region, northern Italy). The subjects were distributed equally for age and sex into four groups: group 1, 20-39 y; group 2, 40-59 y; group 3, 60-75 y; and group 4, > 75 y. A careful selection of subjects to exclude those with chronic or acute diseases was obtained with the collaboration of the three general practitioners operating in Nove.

Triple therapy with sucralfate is not effective in eradicating Helicobacter pylori and does not reduce duodenal ulcer relapse rates.

Objectives: The most used therapeutic schedule to eradicate Helicobacter pylori is the "triple therapy," which is based on the simultaneous use of a bismuth salt and two antibiotics. Sucralfate, a basic aluminum salt of sucrose sulfate, is supposed to have an antibacterial activity and is said to reduce the bacterial density of H. pylori.

Serum uric acid and hypertension: the Olivetti heart study.

The association between serum uric acid and hypertension was evaluated in a sample of male workers in southern Italy enrolled in the Olivetti Heart Study, an ongoing longitudinal epidemiological investigation on risk factors for coronary heart disease carried out at the Olivetti factory in the suburban area of Naples. Participants were screened at baseline (1975) and at five year (1980) and 12 year (1987) follow-up examinations. The present report focuses on 619 male workers for whom information on coronary heart disease risk factors was available both at baseline and 12 year follow-up examination.

Factors affecting the thiobarbituric acid test as index of red blood cell susceptibility to lipid peroxidation: a multivariate analysis.

The relationship between formation of thiobarbituric acid reactive substances (TBARS) in red blood cells (RBC) after exposure to H2O2 and factors potentially able to modulate it was investigated by a multivariate analysis in 92 healthy volunteers. The independent covariates considered were: RBC membrane fatty acids and cholesterol, RBC antioxidant enzymes and zinc, plasma vitamins A and E and serum selenium, zinc and copper. The stepwise multiple-linear-regression analysis revealed RBC membrane fatty acids and cholesterol as predictors of a consistent proportion of the RBC-TBARS variability whereas none of the antioxidants entered the equation.

This report is based on the Health and Activity Limitation Survey, a national survey conducted by Statistics Canada in 1986-87. The overall household prevalence rate of TBI is 62.

Perimenstrual symptom prevalence rates: an Italian-American comparison.

The purposes of this study were to determine the prevalence of perimenstrual symptoms among a randomly selected group of Italian women by using a standardized menstrual symptom instrument and to compare them with those from a census-based sample of free-living American women in the study by Woods et al. (Am J Public Health 1982;72:1257-64). Italian menstrual symptom prevalence rates were obtained as part of a 1984 national health screening project using the Moos Menstrual Distress Questionnaire translated into Italian.

Baldness and coronary heart disease risk factors.

The present report focuses on the association between baldness pattern and coronary heart disease risk factors in 872 male factory workers from southern Italy participating in an epidemiological study. Participants were divided according to presence or absence of baldness and baldness pattern. Participants with fronto-occipital baldness (male-type baldness) (n = 280) characterized by hair loss centered over the vertex with an m-shaped frontal-temporal recession had, on the average, higher serum cholesterol and blood pressure compared to participants with no baldness (n = 321) and/or participants with just frontal baldness (n = 273).

Nucleolar organiser regions of mesothelial and carcinomatous cells in effusions.

The AgNor reaction was performed on effusions and peritoneal washings, and the silver dots were counted on normal or reactive mesothelial cells vs. carcinomatous cells, ascertained by previous HE staining. The mean values were 1.

The relationship between coffee consumption and blood lipids was analyzed in a sample of 900 male workers of southern Italy participating in the Olivetti Heart Study. In the univariate analysis, coffee drinkers (n = 856) had higher values for body mass index (P < or = 0.05) and number of cigarettes smoked per day (P < or = 0.

Alcohol and blood pressure. The effects of age. Findings from the Italian Nine Communities Study. The Research Group ATS-RF2 of the Italian National Research Council.

This report analyzes the role age in the association between alcohol consumption and blood pressure in a large sample (n = 6165) of Italian men and women, aged 20 to 59 years, who participated in a multicenter study on risk factors for arteriosclerosis. Age-stratified analysis indicated that both men and women aged 50 to 59 years showed the strongest positive association between alcohol consumption and blood pressure. While in men the association between systolic blood pressure and alcohol consumption increased linearly with age, in women the association between systolic blood pressure and alcohol increased sharply in the oldest (50 to 59 year) age group.

Predisposition to LDL oxidation in patients with and without angiographically established coronary artery disease.

Oxidative modification of low density lipoprotein (LDL) may play an important role in the mechanism of atherosclerotic damage to blood vessels. In the present study the LDL isolated from the plasmas of 73 coronary artery disease (CAD) patients, 28 valvular heart disease (VHD) patients, 59 subjects affected by type IIa hyperlipoproteinemia and 71 controls was oxidatively modified by incubation with copper ions. In 15 CAD and 15 Type IIa patients and 15 controls the LDL chemical composition and polyunsaturated fatty acid (PUFA) content were also measured.

The presence of pesticide residues in rain, throughfall, stemflow and in ambient air in two Italian forests affected by the forest damage phenomenon were investigated. Pesticides measured were: alachlor, atrazine, carbaryl, 2,4-D, diazinon, dichlobenil, fluazifop-butyl, MCPA, parathion, phorate and trifluralin. Rainwater samples were collected from May to October 1988 at Vallombrosa and Renon, air and atmospheric particulates were sampled during April-June 1989, only at Vallombrosa.

Effects of angiotensin converting enzyme inhibitors and calcium antagonists on atrial natriuretic peptide release and action and on albumin excretion rate in hypertensive insulin-dependent diabetic patients.

Abnormalities in sodium homeostasis and in atrial natriuretic peptide (ANP) behavior could play a role in determining and accelerating the development of glomerular hypertension, hypertension, and microalbuminuria in insulin-dependent diabetes. The aim of the present study was to investigate in 32 hypertensive insulin-dependent diabetic patients (HD) with an altered albumin excretion rate the natriuretic response and ANP release to saline load (2 mmol/kg 90 min, and the effects angiotensin converting enzyme inhibitor therapy 2.5 to 5.

Red blood cells and platelet membrane fatty acids in non-dialyzed and dialyzed uremics.

Three groups of patients with chronic renal failure (CRF), 16 non-dialyzed, 16 undergoing haemodialysis (HD), 16 undergoing continuous ambulatory peritoneal dialysis (CAPD), and 48 controls were examined. We analyzed the fatty acid composition in membranes from erythrocytes and platelets and the platelet malondialdehyde (MDA) production as an index of thromboxane metabolism. Marked differences in erythrocytes fatty acid composition were observed between patients with CRF and controls and, particularly, among the three groups of patients with CRF.

Hematocrit, blood pressure, and hypertension. The Gubbio Population Study.

Baseline data from the Gubbio Population Study in north central Italy were used to investigate the relation of hematocrit to blood pressure and hypertension among 2,809 men and women aged 25-74 years. Independent of gender, age, and other confounders, the hypertensive group had a higher hematocrit than the nonhypertensive group (p less than 0.001).

[Cytopathological test performed during colonoscopy in the diagnosis of colorectal stenosis].

The etiological diagnosis for the colorectal strictures can be very difficult. With the colonoscopy, it was possible to obtain samples with direct vision of the lesion. Consequently, the cytologic efficiency improved, with similar or even better results than histopathology.

Earthquake and coronary heart disease risk factors: a longitudinal study.

The longitudinal association between a number of coronary heart disease risk factors and the experience of a natural disaster (earthquake) was analyzed in a group of workers participating in a longitudinal epidemiologic investigation. The 5-year follow-up examination was interrupted by a major earthquake, and examinations were resumed 2 weeks after the quake. Participants screened after the quake had, on average, higher heart rates, serum cholesterol, and triglycerides than participants examined before the quake; these differences were independent from the coronary heart disease risk factor values measured 5 years previously during the baseline examination.

Coping and blood pressure.

The relationship between psychological coping strategies and BP was analysed in a group of 158 southern Italian men and women aged 20-59, randomly selected from an epidemiological study on coronary heart disease risk factors. Coping strategies were evaluated by use of a self-administered questionnaire (Jalowiec Coping Scale) listing 40 frequently used strategies. Factor analysis revealed the reported use of 5 different coping strategies.
