Studying hypertension in ocular fundus images using Hausdorff dispersion ordering.
2010
Retinal arterial and vein diameters are altered in individuals at risk of cardiovascular events mainly due to high blood pressure. The measurement of retinal vessel diameters has been proved to reflect individuals' vascular health. Dispersion of such measures which are obtained by means of ocular fundus images is a major factor not usually considered in clinical research. In this paper, a method to evaluate if different levels of clinically relevant covariables induce greater dispersion in retinal arterial and vein diameters is proposed. A multivariate dispersion ordering, the Hausdorff dispersion order, is used to compare the level of dispersion in such diameters for different groups of pa…
Geographic Variations in Cardiometabolic Risk Factors in Luxembourg
2017
Cardiovascular disease (CVD) and associated behavioural and metabolic risk factors constitute a major public health concern at a global level. Many reports worldwide have documented different risk profiles for populations with demographic variations. The objective of this study was to examine geographic variations in the top leading cardio metabolic and behavioural risk factors in Luxembourg, in order to provide an overall picture of CVD burden across the country. The analysis conducted was based on data from the nationwide ORISCAV-LUX survey, including 1432 subjects, aged 18-69 years. A self-reported questionnaire, physical examination and blood sampling were performed. Age and sex-adjuste…

COMPARAZIONE DELLE RELAZIONI DI DIFFERENTI DEFINIZIONI DI SINDROME METABOLICA CON L'IPERTROFIA VENTRICOLARE SX NELL'IPERTENSIONE ESSENZIALE
2009
Numerosi studi hanno dimostrato che la sindrome metabolica (SM), sia quando definita secondo i criteri dell'ATPIII, sia quando definita secondo i criteri dell'IDF, si associa ad un aumento della massa del ventricolo sx (VS). Tuttavia, non è noto se queste due differenti definizioni di SM abbiano la stessa capacità di identificare l'ipertrofia del VS (IVS) . Inoltre, una delle critiche mosse al concetto di SM è legata al fatto di essere una variabile dicotomica, limitando in tal modo la possibilità di definire la gravità del rischio cardiovascolare nel singolo paziente. Scopo del nostro studio è stato quello di valutare comparativamente la capacità di differenti definizioni di SM di identifi…
Magnesium Role in Health and Longevity Final
2018
Reduced Magnesium (Mg intake) is a frequent cause of Mg deficit with age. A decreased intestinal Mg absorption and an increased Mg loss may also contribute, as well as the use of medicaments. Mg requirements may be higher with aging. Alterations of Mg metabolism with age, cellular Mg transport systems and problems with measurement methods are discussed. Mg contained in water is more bio-available than Mg in food and it is a possible alternative to Mg supplementation in the correction of Mg deficiencies. Mild to moderate Mg deficits are generally asymptomatic and clinical signs are usually absent or non-specific. Hyperemotionality, tremor, asthenia, sleep disorders, and amnesic and cognitive…
Clinical-anamnestic and instrumental data in outpatients suffering from venous disease
1995
The authors studied 200 consecutive outpatients with symptoms due to venous disease of the lower limbs. All the patients underwent anamnestic, clinical and instrumental evaluation (c.w. Doppler velocimetry and strain-gauge plethysmography). The results of this study showed that some anamnestic and clinical data are significantly related to venous disease detected by instrumental techniques. The superficial and deep vein hypertension were, instead, correlated to oral contraceptive use.
Clinical Inertia in Poorly Controlled Elderly Hypertensive Patients: A Cross-Sectional Study in Spanish Physicians to Ascertain Reasons for Not Inten…
2013
Clinical inertia, the failure of physicians to initiate or intensify therapy when indicated, is a major problem in the management of hypertension and may be more prevalent in elderly patients. Overcoming clinical inertia requires understanding its causes and evaluating certain factors, particularly those related to physicians.The objective of our study was to determine the rate of clinical inertia and the physician-reported reasons for it.An observational, cross-sectional, multi-center study was carried out in a primary care setting. We included 512 physicians, with a consecutive sampling of 1,499 hypertensive patients with clinical inertia.Clinical inertia was defined when physicians did n…
Serum uric acid is not independently associated with plasma renin activity and plasma aldosterone in hypertensive adults
2017
Background and Aims In experimental investigations conducted in rats, raising serum uric acid (SUA) levels resulted in the stimulation of intrarenal renin expression. Studies in humans exploring the association of SUA with plasma renin activity (PRA) yielded conflicting results. Moreover, little is known about the relationship of SUA with plasma aldosterone concentration (PAC). The study aimed to assess the relationship between SUA levels, PRA, and PAC and the influence of age, gender, body mass index (BMI), and hyperuricemia on these relationships in subjects with essential hypertension (EH). Methods and Results We enrolled 372 hypertensive patients (mean age 45 ± 12 years, men 67%) with u…
A Randomized Trial of a Schlemm's Canal Microstent with Phacoemulsification for Reducing Intraocular Pressure in Open-Angle Glaucoma
2014
Purpose To assess the safety and effectiveness of the Hydrus Microstent (Ivantis, Inc, Irvine, CA) with concurrent cataract surgery (CS) for reducing intraocular pressure (IOP) in open-angle glaucoma (OAG). Design Prospective, multicenter, randomized, single-masked, controlled clinical trial. Participants One hundred eyes from 100 patients 21 to 80 years of age with OAG and cataract with IOP of 24 mmHg or less with 4 or fewer hypotensive medications and a washed-out diurnal IOP (DIOP) of 21 to 36 mmHg. Methods On the day of surgery, patients were randomized 1:1 to undergo CS with the microstent or CS alone. Postoperative follow-up was at 1 day, 1 week, and 1, 3, 6, 12, 18, and 24 months. Wa…
