Prevalence and Risk Factors for Vitamin C Deficiency in North and South India: A Two Centre Population Based Study in People Aged 60 Years and Over

2011

BackgroundStudies from the UK and North America have reported vitamin C deficiency in around 1 in 5 men and 1 in 9 women in low income groups. There are few data on vitamin C deficiency in resource poor countries.ObjectivesTo investigate the prevalence of vitamin C deficiency in India.DesignWe carried out a population-based cross-sectional survey in two areas of north and south India. Randomly sampled clusters were enumerated to identify people aged 60 and over. Participants (75% response rate) were interviewed for tobacco, alcohol, cooking fuel use, 24 hour diet recall and underwent anthropometry and blood collection. Vitamin C was measured using an enzyme-based assay in plasma stabilized …

Cross-sectional assessment of nut consumption and obesity, metabolic syndrome and other cardiometabolic risk factors: the PREDIMED study

2013

INTRODUCTION: Prospective studies have consistently suggested that nut consumption is inversely related to fatal and non-fatal coronary heart disease. Limited data are available on the epidemiological associations between nut intake and cardiometabolic risk factors. OBJECTIVE: To evaluate associations between frequency of nut consumption and prevalence of cardiometabolic risk factors [obesity, metabolic syndrome (MetS), type-2 diabetes, hypertension, and dyslipidemia] in a Mediterranean population at high cardiovascular risk. MATERIALS AND METHODS: Cross-sectional study of 7,210 men and women (mean age, 67 y) recruited into the PREDIMED study. MetS was defined by the harmonized ATPIII and I…

Dietary magnesium intake is inversely associated with mortality in adults at high cardiovascular disease risk

2013

The relation between dietary magnesium intake and cardiovascular disease (CVD) or mortality was evaluated in several prospective studies, but few of them have assessed the risk of all-cause mortality, which has never been evaluated in Mediterranean adults at high cardiovascular risk. The aim of this study was to assess the association between magnesium intake and CVD and mortality risk in a Mediterranean population at high cardiovascular risk with high averagemagnesium intake. The present study included 7216 men and women aged 55-80 y fromthe PREDIMED (Prevencíon con Dieta Mediterŕanea) study, a randomized clinical trial. Participants were assigned to 1 of 2 Mediterranean diets (supplemente…

Vitamin D deficiency predicts cognitive decline in older men and women: The Pro.V.A. Study

2014

Objective: To test the hypothesis that hypovitaminosis D is associated with a higher risk of cognitive decline over a 4.4-year follow-up in a large sample of older adults. Methods: This research was part of the Progetto Veneto Anziani (Pro.V.A.), an Italian populationbased cohort study of 1,927 elderly subjects. Serum 25-hydroxyvitamin D (25OHD) levels were measured at the baseline. Global cognitive function was measured with the Mini-Mental State Examination (MMSE); scores lower than 24 were indicative of cognitive dysfunction, and a decline of 3 or more points on the MMSE over the follow-up was considered as clinically significant. Analyses were adjusted for relevant confounders, includin…

Espiritualidad en atención paliativa: Evidencias sobre la intervención con counselling

2015

ResumenLas necesidades espirituales, cuando son elaboradas de forma efectiva, ayudarán a la persona al final de la vida a encontrar significado, mantener la esperanza y aceptar la muerte. El counselling es una de las terapias más utilizadas para mejorar estas necesidades. El objetivo del presente trabajo es ofrecer evidencia sobre la eficacia de esta terapia para la mejora de la espiritualidad de los pacientes atendidos en diversos dispositivos de salud. Para conseguirlo, se llevó a cabo una intervención de tres semanas en 131 pacientes de atención domiciliaria y hospitalizados. Tenían una edad media de 70.61 años (DT = 11.17). El 51.1% eran hombres. Se evaluó la espiritualidad de los pacie…

Perception of quality of life in an elderly Angolan sample / Percepción de calidad de vida en una muestra de ancianos angoleños

2014

AbstractIncreased life expectancy and the ageing of the population have made it particularly important to distinguish between the old (usually 60–79 years, or the ‘young old’) and the oldest old (80 years or more, or the ‘fourth age’). This study explores the effects of age, gender and institutionalization on perceived health and life satisfaction in 1003 elderly people from Luanda, Angola. A multivariate analysis of variance (MANOVA) was estimated to test for these effects. Results provide evidence of lower scores on life satisfaction and perceived health for the oldest old and the institutionalized. However, the higher life satisfaction among the non-institutionalized disappeared when the…

Physical performance in relation to menopause status and physical activity

2018

Objective: The aim of this study was to examine differences in physical performance (muscle power, muscle strength, aerobic capacity, and walking speed) across menopausal stages and potential of leisure physical activity (PA) to modify the impact of menopause on physical performance. Methods: In this cross-sectional study, women aged 47 to 55 were randomly selected from the Finnish National Registry and categorized as premenopausal (n ¼ 233), perimenopausal (n ¼ 381), or postmenopausal (n ¼ 299) based on serum concentrations of follicle-stimulating hormone and bleeding diary. Physical performance was measured by knee extension force, handgrip force, vertical jumping height, maximal walking …

Evolutionary morphology in shape and size of haptoral anchors in 14 Ligophorus spp. (Monogenea: Dactylogyridae).

2017

The search for phylogenetic signal in morphological traits using geometric morphometrics represents a powerful approach to estimate the relative weights of convergence and shared evolutionary history in shaping organismal form. We assessed phylogenetic signal in the form of ventral and dorsal haptoral anchors of 14 species of Ligophorus occurring on grey mullets (Osteichthyes: Mugilidae) from the Mediterranean, the Black Sea and the Sea of Azov. The phylogenetic relationships among these species were mapped onto the morphospaces of shape and size of dorsal and ventral anchors and two different tests were applied to establish whether the spatial positions in the morphospace were dictated by …

Clinical Predictors of Immunotolerance in Heart Transplantation

2010

Abstract Background and Aim The drugs routinely administered to prevent rejection often cause lethal side effects. Tolerant patients, therefore, should be identified to minimize these problems. The aim of this analysis was to identify clinical variables that may be associated with tolerance. Methods We recruited 522 heart transplants (HT), excluding combined procedures, retransplantations, pediatric recipients, and subjects who died in the first year to obtain a cohort of 375 patients. Two groups were distinguished by the presence of echocardiographic, clinical, or pathological evidence of rejection in the first year (15 echocardiograms and 10 protocol biopsies per patient); 99 tolerant pat…
