Abstract
BACKGROUND Lipoprotein apheresis (LA) is the elective therapy for homozygous and other forms of Familial Hypercholesterolemia, Familial Combined Hypercholesterolemia, resistant/intolerant to lipid lowering drugs, and hyper-lipoproteinemia(a). Lipoprotein(a) [Lp(a)] has been classified as the most prevalent genetic risk factor for coronary artery disease and aortic valve stenosis. AIM Our multicenter retrospective study has the aim to analyze the incidence of adverse cardiovascular events (ACVE) before and during the LA treatment, in subjects with elevated level of Lp(a) (>60 mg/dL) [hyper-Lp(a)] and chronic ischemic heart disease. METHODS We collected data of 23 patients (mean age 63 ± 9 years, male 77%; from hospital of Pisa 11/23, Pistoia 7/23, Verona 2/23, Padova 2/23 and Ferrara 1/23), with hyper-Lp(a), pre-apheresis LDL-cholesterol <100 mg/dL, cardiovascular disease, on maximally tolerated lipid lowering therapy and LA treatment (median 7 years, interquartile range 3-9 years). The LA treatment was performed by heparin-induced LDL precipitation apheresis (16/23), dextran-sulphate (4/23), cascade filtration (2/23) and immunoadsorption (1/23). The time lapse between first cardiovascular event and beginning of apheresis was 6 years (interquartile range 1-12 years). RESULTS The recorded ACVE, before and after the LA treatment inception, were 40 and 10 respectively (p < 0.05), notably, the AVCE rates/year were 0.43 and 0.11 respectively (p < 0.05) with a 74% reduction of event occurrence. CONCLUSIONS Our data confirm long-term efficacy and positive impact of LA on morbidity in patients with hyper-Lp(a) and chronic ischemic heart disease on maximally tolerated lipid lowering therapy.

Abstract
AIMS Cardiovascular disease is a major cause of death worldwide. Safety and efficacy of lipid lowering therapy have been clearly established for either primary and secondary prevention of cardiovascular events in adults. Nevertheless, the use of hypolipidemic drugs in elderly individuals, especially in the oldest ones, still raises some concerns. Aim of this paper is to review indications and limits of lipid lowering in advanced age, furnishing a practical medical attitude tempered by clinical and geriatric competences. DATA SYNTHESIS While figures from randomized controlled trials and from observational studies seem to support the use of lipid lowering drugs for secondary prevention in the elderly, drawing inferences from primary prevention in old populations is far more challenging. Although these pharmacological agents seem to reduce the incidence of cardiovascular events, they do not prolong survival. In addition, there is some doubt about the cost-effectiveness of treatment because of a more delicate balance between benefit and potential adverse reactions. However, lipid-lowering drugs seem largely underutilized in older age, mainly due to safety concerns that must be reconsidered, at least in part, given the somewhat reassuring results deriving from specific cohort surveys. CONCLUSIONS Data on the use and on the effects of lipid lowering drugs in elderly populations are incomplete, especially those concerning very old subjects without established cardiovascular disease. Comprehensive guidelines for the management of dyslipidemias in this rapidly-growing population is a urgent need, and treatment should be based, besides the aforementioned considerations, on patient preferences, cognitive function and life expectancy.

Abstract
BACKGROUND Fahr's disease is rare a neurodegenerative idiopathic condition characterized by symmetric and bilateral calcifications of basal ganglia, usually associated with progressive neuropsychiatric dysfunctions and movement disorders. The term "Fahr's syndrome" is used in presence of calcifications secondary to a specific cause, but the variability of etiology, pathogenesis, and clinical picture underlying this condition have raised the question of the real existence of a syndrome. Several classifications based on the etiology, the location of brain calcifications and the clinical presentation have been proposed. Here we describe seven clinical cases of basal ganglia calcifications, in order to search for pathognomonic features and correlations between clinical picture and imaging findings. CASES PRESENTATION The patients came to our attention for different reasons (most of them for memory/behavior disturbances); all underwent neuro-psychologic evaluation and neuro-imaging. All patients showed variable degrees of deterioration in cognitive function; anxiety and depression were frequent too, and resistant to treatment in all cases. Less frequent, but severe if present, were psychotic symptoms, with different grade of structure and emotional involvement, and always resistant to treatment. We observed only few cases of extrapyramidal disorders related to the disease itself; anyway, mild extrapyramidal syndrome occurred quite frequently after treatment with antipsychotics. CONCLUSION Based on these findings we discourage the use of the term "Fahr's syndrome", and suggest to refer to Idiopathic or Secondary basal ganglia calcification. Unlike early onset forms (idiopathic or inherited), the clinical presentation of late onset form and Secondary basal ganglia calcification seems to be really heterogeneous. Case-control studies are necessary to determine the actual significance of basal ganglia calcification in the adult population and in the elderly, in cognitive, physical and emotional terms.

Abstract
AIMS Individuals with type 2 diabetes show shorter leukocyte telomere length (LTL) compared to people without diabetes. Reduced LTL is associated with increased carotid intima-media thickness (IMT) in healthy subjects. The aim of the study is to assess whether LTL also correlates with IMT in patients with diabetes. METHODS In a cohort of 104 subjects with type 2 diabetes and atherogenic dyslipidemia, we assessed anthropometric, hemodynamic and metabolic parameters. Common carotid IMT was expressed as the maximum IMT. LTL was assessed by a specific real-time PCR reaction. RESULTS At univariate analysis, IMT values were positively correlated with age (p < 0.001), previous history of cardiovascular events (p < 0.005), fasting plasma glucose (p < 0.01), HbA1c (p < 0.05) and negatively correlated with LTL (p < 0.05). In a multivariate model, age (p < 0.001) and LTL (p < 0.05) were the only independent predictors of maximum IMT, with an adjusted R (2) of 0.22. CONCLUSIONS LTL is an independent predictor of subclinical atherosclerosis pointing to a role of LTL as an early marker of vascular burden and cardiovascular disease also in type 2 diabetes.

Abstract
Background Diverse research approaches support the concept that a clinical diagnosis of Late-Onset Alzheimer's Disease (LOAD) does not distinguish between subpopulations with differing neuropathologies, including dementia patients with amyloid deposition and dementia patients without amyloid deposition but with cortical thinning. Mild cognitive impairment (MCI) is generally considered the prodromal phase for LOAD, however, while a number of studies have attempted to define plasma biomarkers for the conversion of MCI to LOAD, these studies have not taken into account the heterogeneity of patient cohorts within a clinical phenotype. Methods Studies of MCI and LOAD in several laboratories have demonstrated decrements in ethanolamine plasmalogen levels in plasma and brain and increased levels of diacylglycerols in plasma and brain. To further extend these studies and to address the issue of heterogeneity in MCI and LOAD patient groups we investigated the levels of diacylglycerols and ethanolamine plasmalogens in larger cohorts of patients utilizing, high-resolution (0.2 to 2 ppm mass error) mass spectrometry. Results For the first time, our lipidomics data clearly stratify both MCI and LOAD subjects into 3 different patient cohorts within each clinical diagnosis. These include i) patients with lower circulating ethanolamine plasmalogen levels; ii) patients with augmented plasma diacylglycerol levels; and iii) patients with neither of these lipid alterations. Conclusions These represent the first serum biochemical data to stratify MCI and LOAD patients, advancing efforts to biochemically define patient heterogeneity in cognitive disorders. General significance Lipidomics offers a new approach for identifying biomarkers and biological targets in cognitive disorders. DAGs were increased in the serum of a subset of MCI and AD patient cohorts. Ethanolamine plasmalogens were decreased in a subset of MCI and AD patient cohorts. A subset of MCI and AD patient cohorts had neither of these biochemical alterations. No patient demonstrated both biochemical alterations. These data, for the first time, stratify MCI and AD patient cohorts into at least 3 subgroups.

METHODS AND RESULTS Twenty subjects with primary hyperalphalipoproteinemia (HAL, with HDLc in the highest 10th percentile and absence of overt secondary causes of this condition), aged 30-65 years, were compared with 20 age and sex-matched controls. Lipid determination, lipoprotein particle distribution (Lipoprint(®)), Cholesterol Efflux Capacity (CEC), plasma adhesion molecule, analyses of CETP, SRB1 and LIPG genes and of different markers of subclinical vascular disease (ankle-brachial index, ABI; carotid intima-media thickness, cIMT; brachial-artery flow mediated dilation, FMD) were performed. Fasting HDLc levels were 40 mg/dl higher in HAL subjects while LDLc concentration was comparable to control group. CETP gene analysis in HAL subjects identified one novel rare Single Nucleotide Polymorphism (SNP, Asp131Asn), possibly damaging, while the common SNP p.Val422Ile was highly prevalent (50% vs. 27.4% in a control population). No rare mutations associated with HAL were found in SR-B1 and LIPG genes. Polyacrylamide gel electrophoresis in HAL subjects disclosed larger and more buoyant HDL particles than in controls, while LDL profile was much more similar. ABI, cIMT and arterial plaques did not differ in cases and controls and the two groups showed comparable FMD at brachial artery examination. Similarly, ABCA1 and ABCG1 HDL-mediated CEC, the most relevant for atheroprotection, did not discriminate between the groups and only ABCG1 pathway seemed somewhat related to arterial reactivity. CONCLUSIONS HDL dimension, function and genetics seem scarcely related to subclinical atherosclerosis and vascular reactivity in middle-aged HAL subjects.

Abstract
BACKGROUND Patients with homozygous familial hypercholesterolaemia respond inadequately to existing drugs. We aimed to assess the efficacy and safety of the microsomal triglyceride transfer protein inhibitor lomitapide in adults with this disease. METHODS We did a single-arm, open-label, phase 3 study of lomitapide for treatment of patients with homozygous familial hypercholesterolemia. Current lipid lowering therapy was maintained from 6 weeks before baseline through to at least week 26. Lomitapide dose was escalated on the basis of safety and tolerability from 5 mg to a maximum of 60 mg a day. The primary endpoint was mean percent change in levels of LDL cholesterol from baseline to week 26, after which patients remained on lomitapide through to week 78 for safety assessment. Percent change from baseline to week 26 was assessed with a mixed linear model. FINDINGS 29 men and women with homozygous familial hypercholesterolaemia, aged 18 years or older, were recruited from 11 centres in four countries (USA, Canada, South Africa, and Italy). 23 of 29 enrolled patients completed both the efficacy phase (26 weeks) and the full study (78 weeks). The median dose of lomitapide was 40 mg a day. LDL cholesterol was reduced by 50% (95% CI -62 to -39) from baseline (mean 8·7 mmol/L [SD 2·9]) to week 26 (4·3 mmol/L [2·5]; p<0·0001). Levels of LDL cholesterol were lower than 2·6 mmol/L in eight patients at 26 weeks. Concentrations of LDL cholesterol remained reduced by 44% (95% CI -57 to -31; p<0·0001) at week 56 and 38% (-52 to -24; p<0·0001) at week 78. Gastrointestinal symptoms were the most common adverse event. Four patients had aminotransaminase levels of more than five times the upper limit of normal, which resolved after dose reduction or temporary interruption of lomitapide. No patient permanently discontinued treatment because of liver abnormalities. INTERPRETATION Our study suggests that treatment with lomitapide could be a valuable drug in the management of homozygous familial hypercholesterolaemia.

Abstract
Oxidized LDLs (ox.LDLs) uptake by macrophages inside the arterial wall is a crucial step in atherosclerotic disease, and some studies suggest that high ox.LDLs plasma levels might be associated with cardiovascular disease (CVD). However, whether high ox.LDLs continue to be a CVD risk factors in older persons is unknown. We investigated the clinical correlates of plasma ox.LDLs, and their role in predicting long-term CVD/cardiac mortality in 1025 older community dwelling individuals (mean age: 75.5 ± 7.4 years; females: 55%) from the InCHIANTI study. Kaplan-Meier curves were fitted to explore the relationship between tertiles of ox.LDLs (ox.LDL/LDL-C ratio) and time to CVD/cardiac death. Hazard Ratios (HR) were estimated by Cox regression analysis. At multivariate analysis, ox.LDLs were independently associated with LDL-C, triglycerides, and HDL-C (adjusted r(2): 0.42; P = 0.001). The ox.LDL/LDL-C ratio (the extent of LDLs oxidation) was independently correlated with HDL-C, triglycerides, and beta-carotene (adjusted r(2): 0.15, P = 0.001). Among 1025 individuals, 392 died after 9 years, 166 from CVD. The HR for CVD/cardiac mortality was not significantly different across tertiles of ox.LDLs or ox.LDL/LDL-C ratio, both in the whole sample and in individuals with prevalent CVD. We conclude that in an elderly population LDL-C, triglycerides, and HDL-C are the most important determinants of ox.LDLs levels, indirectly suggesting an association between small dense LDLs and LDLs oxidation. No association emerged between higher ox.LDLs levels and 9 years CVD/cardiac mortality, suggesting that in advanced age the prognostic information added by ox.LDLs on CVD/cardiac mortality might be negligible.

Abstract
The primary aim of the STAR Study (Statins Target Assessment in Real practice) was to determine the LDL-cholesterol reduction and to analyse patient's and therapeutic factors associated to LDL-cholesterol target attainment in newly treated subjects with statins in an unselected population in clinical practice setting. Administrative databases (including pharmaceutical prescriptions and hospital admissions) and laboratory test databases (including LDL-cholesterol values) of five local health units, distributed in Emilia Romagna, Toscana and Umbria, were linked. A retrospective cohort study was conducted and all subjects aged > or =18 years with a first prescription for statins (newly treated subjects) between January 1st, 2007 and June 30th, 2008 were included. All statin prescriptions over a 12 months follow-up period were considered and used to calculate adherence to treatment. Baseline and follow-up LDL-cholesterol, respectively, were defined according to the nearest determination to the first prescription for statins and to the end of the follow-up period. A total of 3.232 subjects was included, 1.516 males (47%) and 1.716 females (53%), with an average age equal to 65.9 +/- 11.3 years. Among included subjects, 22.,6% had a gap to LDL-cholesterol target <10%, 30.0% between 10 and 29%, 20.7% between 30 and 49%, and 26.7% . or =50%. Among those with a gap to target > or =50%, 30-49%, and 10-29%, respectively, LDL-cholesterol target was attained by 7.1%, 41.8%, and 62.% of subjects. LDL-cholesterol target attainment was associated to gap to target, adherence with treatment, and type of statin.

Abstract
Lipoprotein(a) (Lp[a]) may represent an independent risk factor for peripheral arterial disease of the lower limbs (LL-PAD), but prospective data are scant. We estimated the association between baseline Lp(a) with prevalent and incident LL-PAD in older subjects from the InCHIANTI Study. LL-PAD, defined as an ankle-brachial index <0.90, was assessed at baseline and over a 6-year follow-up in a sample of 1,002 Italian subjects 60 to 96 years of age. Plasma Lp(a) and potential traditional and novel cardiovascular risk factors (including a score based on relevant inflammatory markers) were entered in multivariable models to assess their association with prevalent and incident LL-PAD. At baseline, Lp(a) concentration was directly related to the number of increased inflammatory markers (p <0.05). There were 125 (12.5%) prevalent cases of LL-PAD and 57 (8.3%) incident cases. After adjustment for potential confounders, participants in the highest quartile of the Lp(a) distribution (>/=32.9 mg/dl) were more likely to have LL-PAD compared to those in the lowest quartile (odds ratio [OR] 1.83, 95% confidence interval [CI] 1.01 to 3.33). The association was stronger (OR 3.80, 95% CI 1.50 to 9.61) if LL-PAD was defined by harder criteria, namely an ankle-brachial index <0.70. Compared to subjects in the lowest Lp(a) quartile, those in the highest quartile showed a somewhat increased risk of incident LL-PAD (lowest quartile 7.7%, highest quartile 10.8%), but the association was not statistically significant (OR 1.52, 95% CI 0.71 to 3.22). In conclusion, Lp(a) is an independent LL-PAD correlate in the cross-sectional evaluation, but further prospective studies in larger populations, with longer follow-up and more definite LL-PAD ranking, might be needed to establish a longitudinal association.

Abstract
Over the last decades, testosterone replacement therapy for middle-aged and older men has been gaining increasing and widespread attention and popularity. Although several benefits of testosterone replacement therapy are well established, including but not limited to improvement in libido, body composition, and bone density, concerns for multiple potential adverse effects remain. In particular, concerns are frequently raised regarding the possibility that testosterone replacement therapy may increase the risks of prostate cancer and cardiovascular disease as consequence of a potential detrimental effect of testosterone on cardiovascular risk factors. This mini-review will present and discuss the current knowledge on the relationship between testosterone replacement therapy and change in lipid fractions in older men.

Abstract
Low density lipoprotein (LDL) oxidative modification in the vascular wall seems to be a key factor in atherosclerosis development. Oxidised LDLs might recruit monocytes and favour their transformation into foam cells through a receptor-mediated intake (scavenger pathway). Moreover oxidised LDLs show cytotoxic potential which is probably responsible for endothelial cell damage and macrophage degeneration in the atherosclerotic human plaque. Following the oxidation hypothesis of atherosclerosis the role of natural antioxidants, i.e. Vitamin C, Vitamin E and carotenoids, has been investigated in a large number of epidemiological, clinical and experimental studies. Animal studies indicate that dietary antioxidants may reduce atherosclerosis progression, and observational data in humans suggest that antioxidant vitamin ingestion is associated with reduced cardiovascular disease, but the results of randomised controlled trials are mainly disappointing. It has been suggested that natural antioxidants may be effective only in selected subgroups of patients with high levels of oxidative stress or depletion of natural antioxidant defence systems. The favourable effects shown by some studies relating antioxidant dietary intake and cardiovascular disease, may have been exerted by other chemicals present in foods. Flavonoids are the ideal candidates, since they are plentiful in foods containing antioxidant vitamins (i.e. fruits and vegetables) and are potent antioxidants. Tea and wine, rich in flavonoids, seem to have beneficial effects on multiple mechanisms involved in atherosclerosis. Future studies should probably select patients in a context of high-oxidative stress / low-antioxidant defence, to verify if antioxidants may really prove useful as therapeutic anti-atherosclerotic agents.

Abstract
Investigations concerning the role of testosterone replacement on cardiovascular risk show conflicting results. Treatments with supraphysiological doses seem detrimental in animal models and men. On the other hand, cross-sectional, prospective and angiographic studies frequently find an inverse, favorable relationship between plasma testosterone and cardiovascular events. Testosterone replacement therapy in the hypogonadic elderly has a positive or at least neutral effect on several coronary disease risk factors. Testosterone appears to decrease LDL-cholesterol without adversely affecting HDL cholesterol, and improve insulin sensibility and the thrombotic/fibrinolytic balance; testosterone does not negatively influence the inflammatory response and arterial wall vasoreactivity. These findings provide a measure of reassurance concerning potential adverse heart effects of testosterone substitutional therapy in older men, even if more specific trials than reported are needed to overcome residual suspicions.

Abstract
It is widely recognised that post-prandial lipoproteins play a role in the development of atherosclerosis, but the mechanisms underlying this role are unclear. An attractive working hypothesis is that the pathogenetic link is endothelial dysfunction. The available data seem to corroborate this theory and recognise triggering by oxidative stress, but some of the evidence is still contradictory.

Abstract
OBJECTIVE This study evaluates the hospitalization risk for upper gastrointestinal bleeding (UGIB) with reference to the clinical characteristics of patients and drugs taken before admission. METHODS This study is based on the GIFA (Italian Group for the Pharmacosurveillance in the Elderly) database. Cases with an ICD-9 code of esophagus, stomach or duodenum bleeding, or acute esophago-gastroduodenal disease associated with anemia have been classified as UGIB. Sex, age, year of observation, drugs taken at home, comorbidity, smoking, alcohol, and use of gastroprotectants have been also taken into account. Statistical analysis has been conducted using multivariate logistic regression models. RESULTS 32,388 patients have been enrolled, 940 of which presented UGIB. Age, comorbidity, use of smoke and alcohol, hospitalization duration, and mortality during hospitalization were significantly higher in UGIB than nonUGIB patients. Increased UGIB risk has been found in patients taking NSAIDs (both when aspirin was included or excluded), acetaminophen, constipating agents, iron, ethacrynic acid, propranolol. Reduced UGIB risk has been found in patients taking nitrates. CONCLUSIONS UGIB risk appears to correlate with clinical characteristics of the patient: it increases with age, comorbidity, and smoke and alcohol consumption. Among drugs, NSAIDs are associated with the highest UGIB risk, while nitrates with a reduction of risk.

Abstract
The aim of our study was to evaluate the effect of a standardized formulation of a polyphenolic extract of grapes (Leucoselect-Phytosome [LP]) on low-density lipoprotein (LDL) susceptibility to oxidation in a group of heavy smokers. A randomized, double-blind, crossover study was undertaken in 24 healthy male heavy smokers, aged > or = 50 years. Enrolled subjects were given 2 capsules twice daily for 4 weeks (phase 1). Each capsule contained 75 mg of a grape procyanidin extracts and soy-phosphatidlcholine or placebo consisiting of 75 mg lactose and soy-phosphatidlcholine. A wash out period of 3 weeks was then followed by 4 weeks of the opposite treatment (phase 2). Blood samples were taken at baseline and at the end of each phase and assayed for plasma lipids and LDL susceptibility to oxidation. Compliance was good, and no adverse effects were recorded. Subjects did not show significant modification of total cholesterol (TC), triglycerides (TG), high-density lipoprotein-cholesterol (HDL-C) and LDL-C during LP treatment. Among oxidative indices, thiobarbituric acid reactive substances (TBARS) concentration was significantly reduced in subjects taking LP (-14.7% +/- 21.1% v +5.0% +/- 18.1%, P <.01), and the lag phase prolonged (+15.4% +/- 24.4% v -0.1% +/- 16.0%, P <.05) compared with placebo and basal values. The antioxidant potential of grape seed extract polyphenols may prove effective in a model of oxidative stress (smoking); however more investigational data are needed before use in wider clinical settings.

Abstract
Hormone replacement therapy (HRT) seems to have a favorable influence on the plasma lipid profile. Only a few investigations have examined the effects of HRT versus hepatic hydroxymethyl glutaryl coenzyme A (HMG-CoA) reductase inhibitors. We compared the relative effects of different hypolipidemic strategies on lipoproteins and coagulative parameters in women with recent-onset spontaneous menopause. In this 24-week, placebo-controlled trial, 60 consecutive healthy women aged >/= 45 years, with amenorrhea from 6 to 60 months (mean, 1.9 +/- 1.4 years), serum follicle stimulating hormone (FSH) greater than 40 U/L, and slight to moderate hypercholesterolemia (low-density lipoprotein-cholesterol [LDL-C] 160 to 250 mg/dL, high-density lipoprotein-cholesterol [HDL-C] < 75 mg/dL, and triglycerides < 200 mg/dL) were enrolled and randomized to dietetic advice (placebo group), simvastatin 10 mg, 0.625 mg of conjugated equine estrogen (CEE), or 50 microg estrogen transdermal patch (ETP). In the latter 2 cases, the progestative nomegestrol was added to estrogens (days 17 to 28 of the cicle). Lipoprotein parameters were evaluated after separating very-low-density lipoproteins (VLDLs) by ultracentrifugation, while fasting glucose and insulin, homocysteine, and hemocoagulative parameters were determined in plasma. Fifty-four patients completed the trial. Total cholesterol (TC) and LDL-C significantly decrased in the simvastatin (-62 mg/dL [-20%] and -72 mg/dL [-30%], respectively), CEE (-42 mg/dL [-13%] and -45 mg/dL [-18%]), and ETP (-30 mg/dL [-10%] and -26 mg/dL [-11%]) groups compared to baseline, but only simvastatin showed an effect significantly superior to diet alone. Apolipoprotein (Apo) B was decreased by simvastatin (-25%, P <.001) and by CEE (-10%, P <.05); again, simvastatin was more effective than either diet or ETP. Triglyceride concentration and VLDL-C were unmodified by treatments. HDL-C and Apo A-I significantly increased in the simvastatin group (+18% and +8%, respectively), while HDL-C was unmodified by both HRT regimens and Apo A-I was reduced by ETP treatment (-17%); lipoprotein[a] (Lp[a]) was decreased by both HRTs (-38%, P <.05, and -22%, P =.07, for CEE and ETP, respectively). Among coagulative parameters, plasminogen activator inhibitor-1 (PAI-1) was significantly reduced by CEE (-29%, P <.05) but not ETP treatment (+16%, P = not significant), while fibrinogen, antithrombin, and homocysteine were unaffected by therapy. Thus, HRT, particularly CEE, seems well tolerated and moderately effective in improving the lipid pattern and, perhaps, the coagulative/fibrinolytic balance in postmenopausal hypercholesterolemic women; it may represent a therapeutic option in slightly dyslipidemic subjects. Statins are preferred in case of more severe disease.

Abstract
BACKGROUND AND AIM Postmenopausal modification of the lipid profile plays a major role in the risk of ischemic heart disease. Lifestyle counseling and estrogen replacement therapy have all been proposed as first-line measures, but there is no agreement on the best way to treat climacteric dyslipidemia. Soybean-based diet seems particularly attractive in this context, given its cholesterol lowering potential, its hypothetical anticancerous effects and possible modification of climacteric symptoms. METHODS AND RESULTS We evaluated the effect of 60 g isolated soy protein (ISP) daily on the lipid profile of 104 postmenopausal women (53.3 +/- 3.3 years) in a double-blind, parallel, placebo-controlled (caseinate) trial, as part of a broader assessment of the effect of ISP on climacteric symptomatology. Serum total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, apo A-I, apo B and lipoprotein (a) were determined before and after a 12-week diet modification. Seventy-seven women completed the trial. Both soy and placebo determined a significant reduction in total cholesterol (-0.42 +/- 0.79 and -0.40 +/- 0.57 mmol/L) and LDL-cholesterol (-0.35 +/- 0.72 and -0.31 +/- 0.54 mmol/L), but only soy had a significant lowering effect on apo B and the LDL-cholesterol/HDL-cholesterol ratio (-6% and -8% from baseline respectively); lipoprotein (a) plasma levels were not significantly changed by either treatment. Forty-four women were dyslipidemic at baseline; those with increased LDL concentrations showed a somewhat greater improvement in their lipoprotein profile (LDL-cholesterol and apo B reduction) with soy rather than placebo. No further information emerged when the subjects were divided into three apo E phenotypes. CONCLUSIONS We conclude that diet supplementation with 60 g ISP is slightly better than caseinate in favorably modifying the lipoprotein metabolism of postmenopausal women; this effect is more evident in hypercholesterolemic subjects.

Abstract
We report the case of a 52-year-old woman with recent diagnosis of acute myocarditis and pericarditis, admitted for fever, tachycardia, and dyspnea upon exertion. Hematochemical parameters and instrumental examinations suggested iatrogenic hyperthyroidism and secondary dilated cardiomyopathy. Although gathering information about the medication used at home was initially difficult because of the patient's refusal to cooperate, she ended up by disclosing the regular assumption of an iodocasein drug. A complete and stable regression of the clinical picture was reached by suspending the iodine derivative and using cardiovascular drugs.

Abstract
BACKGROUND AND AIM Impaired triglyceride-rich lipoprotein metabolism is most probably related to an enhanced cardiovascular risk, and may be associated with a pro-coagulant state. A double-blind, randomized study was undertaken to evaluate two widely utilized hypolipidemic drugs in the post-prandial phase and their impact on lipid, coagulation and fibrinolytic parameters. METHODS AND RESULTS Thirty middle-aged men selected according to their low density lipoprotein-cholesterol (LDL-C) > or = 160 and < or = 240 mg/dl and borderline hypertriglyceridemia (110-220 mg/dl) after at least one month of a lipid-lowering diet received gemfibrozil (600 mg bid) or simvastatin (20 mg qd) and the corresponding placebo. On enrollment and after 2 months of drug treatment, they were tested with a standard oral fat load (OFL) (35 g fat/m2 body surface). On both occasions plasma total-cholesterol, LDL-C, HDL-C, triglycerides, lipoprotein[a] (Lp[a]), tissue plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1), antithrombin-III (AT-III), plasminogen and fibrinogen were determined just before the meal (t0) and at times 2 hours, 4 h, 6 h, 8 h after it (t2-t8). A two-factor (time and visit) multivariate analysis for repeated measurements was performed to evaluate the data. Total cholesterol, and LDL-C were significantly diminished 2 months after both gemfibrozil and simvastatin, the latter being more active. Plasma triglycerides showed a marked reduction with gemfibrozil at all times, while simvastatin regimen yielded only minor modifications. HDL-C was only slightly increased by simvastatin; Lp[a] plasma levels were almost unaffected. Small fibrinogen (t0, t2, t6, t8), PAI-1 (t6) and AT III (t0-t8) increases were observed after gemfibrozil, while simvastatin did not significantly modify these parameters. CONCLUSIONS In the post-prandial phase, gemfibrozil and simvastatin induce different metabolic effects that beneficially influence the lipid pattern, whereas fibrinolytic and coagulative parameters display minor variations of undetermined significance.

Abstract
BACKGROUND Hypothyroidism is a frequent cause of hyperlipidemia, particularly in women, but its true prevalence, both in the general population and in dyslipidemic subjects, is unknown. It is uncertain if low thyroid function significantly influence HDL metabolism and if sub-clinical disease may cause metabolic abnormalities and increase cardiovascular risk. METHODS Three-hundred and three consecutive female patients (mean age 59.2 +/- 0.5 yrs), observed in a metabolic ward because of dyslipidemia, were evaluated. RESULTS Forty-three women (14.1% of the total) showed sub-clinical hypothyroidism, while in 12 cases (4.0%) overt hypothyroidism was diagnosed; 8 further women (2.6%) had been previously diagnosed to be hypothyroid and were under hormone replacement therapy. On the whole, hypothyroid patients showed higher mean triglyceride levels and lower HDL-cholesterol than dyslipidemic euthyroid women, but the difference did not reach statistical significance. Total cholesterol concentration did not change with impaired thyroid function. Hypothyroid patients reported a clinical history of cardiovascular disease, or had severe atherosclerosis demonstrated, more often than euthyroid subjects (25.0% vs 19.7%, p = n.s.). When only women with arterial disease were considered, HDL plasma levels were significantly lower in the hypothyroid than in the euthyroid group (44.3 +/- 3.1 vs 56.2 +/- 1.7 mg/dl, respectively; p < 0.01). Hypertriglyceridemia and obesity often coexisted. CONCLUSIONS In conclusion, among dyslipidemic women, unrecognised hypothyroidism is highly prevalent (both sub-clinical and manifest). In hypothyroid subjects atherosclerosis seem to associate with particularly low HDL plasma levels. This might precede atherosclerosis development (reinforced by concomitant thyroid failure) and represent a marker of the polymetabolic syndrome.

Abstract
Patients with homozygous beta-thalassemia show an abnormal lipoprotein profile. In asymptomatic heterozygotes the lipid pattern is less markedly affected but interestingly related to a diminished cardiovascular risk. The extent and significance of these findings are still a matter of debate and no data are available on lipoprotein(a) plasma levels. Seventy patients with homozygous beta-thalassemia (HT-P), 70 beta-thalassemia trait carriers (TT-C) and 70 sex and age-matched controls were investigated and their plasma lipoprotein profile and apo(a) phenotypes determined. In a subgroup of these same subjects (12 HT-P, 12 TT-C and 24 controls) and in 12 bone marrow-transplanted homozygous beta-thalassemic patients (BMT-P) plasma lipoprotein composition was assessed. HT-P disclosed significantly lower total-cholesterol, LDL-cholesterol, HDL-cholesterol, apo A-I, apo B plasma levels and higher triglyceride concentration than TT-C (-7, -11, -8, -8, -13 and +11%, respectively) or controls (-39, -50, -46, -32, -30 and + 35%, respectively). All lipoprotein subclasses were triglyceride-enriched, while LDLs were also protein-enriched and HDLs protein-depleted. TT-C disclosed a small but significant reduction in apo A-I and apo B plasma levels but only minor lipoprotein abnormalities with respect to the controls. BMT-P lipoprotein composition was intermediate between HT-P and normal subjects. Apo(a) plasma levels did not differ among the groups. A higher prevalence of 'small' apo(a) isoforms was present in HT-P. Within the same 'isoform group', apo(a) plasma levels were significantly lower in HT-P than in TT-C or controls. Since liver cirrhosis is almost always present in HT-P, it is conceivable that an altered hepatic apo(a) synthesis or catabolism due perhaps to diminished apolipoprotein glycation may be involved. In TT-C a partially improved cardiovascular risk profile was apparent (low hematocrit, low LDL-cholesterol and apo B), thus justifying the claim for a low prevalence of ischemic heart disease, but no Lp(a) plasma level modification could be detected.

Abstract
BACKGROUND AND PURPOSE Stroke is the third main cause of death in western countries. To evaluate its ever-changing characteristics and the impact of recent public campaigns on cardiovascular risk factors (CRFs) in stroke morbidity and mortality, we carried out a retrospective investigation on subjects with cerebrovascular disease in different periods. METHODS All clinical data of patients with acute cerebrovascular disease (TIA or stroke) admitted to a regional hospital (Padua, Italy) during two distinct years (1985 and 1992) were examined (381 in 1985 and 440 in 1992). In every case the characteristics of the episode, clinical course, concomitant CRFs and relevant biochemical and instrumental examinations were recorded. RESULTS Altogether Transient Ischemic Attack (TIA) represented almost half the records; remaining cases could be classified as ischemic stroke (66% vs 55%), Intracerebral Haemorrhage (17% vs 26%) and subarachnoideal haemorrhage (17% vs 19%) (1985 vs 1992, respectively). The mean hospitalization period was longer in the most recent year, particularly in haemorrhagic patients (H-P, subarachnoid + intracerebral haemorrhage); the in-hospital case fatality rate was reduced in HP while it was significantly increased in those with Cerebral Ischemia (CI-P, TIA + ischemic stroke). The prevalence of blood hypertension, atrial fibrillation and dyslipidaemias rose significantly in 1992 compared to 1985. High plasma lipids were more frequently present in CI-P than in H-P; their 7-year increase was particularly related to combined forms, rather then isolated hypercholesterolemia or hypertriglyceridemia. CONCLUSIONS These results do not agree with an hypothetical improvement in the prognosis of stroke in the period we considered. Besides the efforts aiming at reducing CRFs in the short term have not shown to be successful.

Abstract
Peripheral atherosclerosis (carotid and aortofemoral vascular districts) shows some peculiar characteristics with respect to coronary atherosclerosis. In this paper we have reviewed the most recent studies on the relationships between atherosclerosis of the limbs and lipid metabolism. Several authors have described increased plasma levels of lipoprotein remnants, lipoprotein (a) and some lipid peroxidation parameters in extracoronary atherosclerosis, while HDL (and their subfractions) seem to be reduced. Some of these modifications may be related to the direct metabolic effects of smoking and diabetes, which frequently coexist. Recent intervention trials show a possible regression of established atherosclerotic plaques after hypolipidemic therapy. This further underscores the role of plasma lipoprotein pattern in determining peripheral vascular lesions.

Abstract
A family presenting several cases of severe primary hypercholesterolaemia and/or premature sudden death was studied. This family is characterized by consanguinity, absence of vertical transmission, bimodal distribution of plasma cholesterol values, and reduction of reproductive fitness in affected individuals. The probands have clinical traits of homozygous familial hypercholesterolaemia, including hypercholesterolaemia, xanthomas and early coronary atherosclerosis, while the parents and grandparents are clinically normal. Eight relatives on the mother's side experienced premature sudden death, and in four cases hypercholesterolaemia was diagnosed. Haplotype segregation analysis of the inheritance of the LDL receptor and apo B genes in the probands' family excluded the involvement of these two genes in the pathogenesis of the disease. LDL receptor activity, as well as the ability of LDL to bind to the LDL receptor, and plasma vegetal sterols were within normal limits both in probands and in their relatives. The study of this pedigree suggests that hypercholesterolaemia is not produced by defects in the LDL receptor or LDL particles, and disease inheritance is consistent with an autosomal recessive trait.

Abstract
The influence of age on the response of plasma lipids, body composition, and cardiovascular performance to physical training and detraining was studied in 12 older and 12 young adult male cyclists. The athletes were first examined at the peak of their seasonal preparation and then again 2 months after its suspension. Sedentary males matched for age, weight, and height comprised the respective control groups. During training, body fat mass (BFM) was significantly lower and maximum oxygen consumption (VO2max) higher in both groups of cyclists as compared with controls. No differences in serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), apolipoprotein (apo) B, apo A-II, and fibrinogen were found. During the same phase, triglycerides (TG) and the LDL-C to high-density lipoprotein cholesterol (HDL-C) ratio were significantly lower and apo A-I, HDL-C, HDL3-C, and the apo A-I/apo B ratio were significantly higher in the athletes than in their corresponding sedentary controls. After physical deconditioning, BFM increased and VO2max decreased significantly in both groups of athletes. TG, very-low-density lipoprotein cholesterol (VLDL-C), and fibrinogen increased in young athletes while the LDL-C/HDL-C ratio increased, and apo A-I, HDL-C, HDL2-C, and HDL3-C decreased significantly in both young and older athletes. Thus, an aerobic training program induced an antiatherogenic lipoprotein profile and beneficial modifications in body composition and aerobic power in both older and younger subjects; a 2-month interruption in the program changed these parameters unfavorably in both groups. Age does not seem to influence significantly the plasma lipid response to physical deconditioning.

Abstract
In this study we evaluated the potential differences in normal electrocardiographic parameters between two groups of young patients belonging to different races (Caucasians and Blacks). For this purpose 100 electrocardiograms had been taken, coded and compared in 50 Italian males and 50 north-Africans who came to an Emergency Department because of minor condition. On the whole we could not find significant differences between the two groups, except for a small increase in P-wave duration in black people. We conclude that the same parameters used to evaluate normal electrocardiograms in white people, may be satisfactory applied also for black individuals. This fact is worthy of attention since more and more extracomunitarian patients are addressing the Italian Health Service.

Abstract
Several diseases, and particularly cardiovascular affections, show a periodic fluctuation in their occurrence. We investigated acute myocardial infarction (AMI) incidence in connection with the day of the week, looking for a link with psycho-social phenomena. Eight hundred and fifty-two patients with AMI were considered: they had been admitted to the emergency department of two main towns of northeastern Italy during a calendar year. Eight hundred and seventeen (533 men, 284 women) were eligible for the purpose of this study. The time of symptom onset was recorded, cardiovascular risk factors and occupational condition were evaluated. All data were analyzed through chi-square test of uniformity and Halberg single cosinor test. No statistically significant difference from the uniform distribution appeared in acute events occurrence both in patients as a whole and in single subgroups subdivided according to gender and age. However, the preferential distribution during the days of the week was somewhat different between men (highest incidence at the extreme of the week) and women (highest incidence about mid-week). Statistically significant differences in AMI occurrence in the week were evidenced when patients were analyzed after subdivision according to their occupational condition: working subjects, in comparison with not-working individuals, showed a higher AMI incidence at the beginning of the week with respect to subsequent days. It is therefore likely that the stress associated with the return to work (according to the weekly working pattern of western society) represents an additional important cause of AMI. The mechanisms for that are only speculative.

Abstract
The concentration of lithogenic and antilithogenic substances in urine shows circadian fluctuations. With this investigation we intended to verify the presence of a chronobiologic rhythm of colic pain in urinary tract calculosis. Four hundred and forty seven consecutive patients with a clinical symptomatology related to urinary tract colic pain were studied. They were subdivided according to sex and age (297 M, 150 F; > or = 65 ys 29, < 65 ys 428). Urinary and blood chemical analysis and instrumental examinations permitted to confirm the clinical diagnosis. To evaluate the circadian and circannual variability, acute events were grouped into one calendar year by the month and into a ideal day by the hour of occurrence respectively. Chronobiologic analysis was performed utilising Halberg single cosinor test. The results pointed out that the symptomatology related to urinary tract colic pain presents a circadian rhythmicity either in patients as a whole or in single subgroups (males, females, younger or older than 65 ys). Besides no seasonal variability was demonstrated, perhaps because of the mild climate present in the geographic area in which the study was carried on.

Abstract
BACKGROUND Different patterns of risk factors might be related to the involvement of specific vascular districts by atherosclerosis. In this sense, many investigations have addressed coronary artery disease, whereas extracoronary atherosclerosis has received less extensive attention. METHODS AND RESULTS Vascular risk factors, with particular attention to lipid parameters (total cholesterol [TC]; triglycerides; high density lipoprotein cholesterol [HDL-C], HDL2 and HDL3 cholesterol [HDL2-C, HDL3-C]), were evaluated by means of univariate and multivariate (discriminant) analysis in a group of 169 patients (128 men and 41 women; mean ages, 58 +/- 7 and 62 +/- 7 years, respectively) with clinically and angiographically demonstrated atherosclerosis of the supra-aortic trunk and/or lower limbs. Patients with coronary artery disease were excluded from this study. The control group consisted of 140 age- and sex-matched individuals. By univariate analysis, smoking was more closely associated with peripheral atherosclerosis, whereas blood pressure was higher in patients with supra-aortic disease. Unrecognized diabetes mellitus was a frequent finding in patients with peripheral disease. The percentage of hyperlipidemias was fourfold higher in patients than in control subjects, with differences consisting of higher triglycerides and lower HDL-C, HDL2-C, and HDL3-C concentrations. By discriminant analysis, high correct classification (CC) rates were achieved in the various patient subgroups on the basis of variables selected from the statistical function. In male patients with peripheral disease, the variables HDL-C, smoking, diastolic blood pressure, uric acid, and glucose, in that order, yielded a CC in 90.4% of the cases; in female patients, smoking, TC/HDL-C, and body mass index gave a CC rate of 95.9%. In men with cerebral disease, the selected variables TC/HDL-C, diastolic blood pressure, and TC yielded a CC of 90.7%; in women, uric acid, TC/HDL-C, and fibrinogen levels produced a CC rate of 89.2%. CONCLUSIONS Risk profiles in atherosclerosis of the supra-aortic trunks and lower limbs seem to differ in relation to gender and circulatory district involved. The importance of lipid parameters, in particular HDL-C, HDL2-C, and TC/HDL-C, as extracoronary risk factors is further confirmed.
