Olive oil intake and risk of cardiovascular disease and mortality in the PREDIMED Study
2014
[Background] It is unknown whether individuals at high cardiovascular risk sustain a benefit in cardiovascular disease from increased olive oil consumption. The aim was to assess the association between total olive oil intake, its varieties (extra virgin and common olive oil) and the risk of cardiovascular disease and mortality in a Mediterranean population at high cardiovascular risk.
Nitrate and nitrite in the diet: How to assess their benefit and risk for human health
2015
Nitrate is a natural constituent of the human diet and an approved food additive. It can be partially converted to nitrogen monoxide, which induces vasodilation and thereby decreases blood pressure. This effect is associated with a reduced risk regarding cardiovascular disease, myocardial infarction, and stroke. Moreover, dietary nitrate has been associated with beneficial effects in patients with gastric ulcer, renal failure, or metabolic syndrome. Recent studies indicate that such beneficial health effects due to dietary nitrate may be achievable at intake levels resulting from the daily consumption of nitrate-rich vegetables. N-nitroso compounds are endogenously formed in humans. However…
Cardiovascular disease: pathophysiological mechanisms
2015
OSA is a common disease that affects approximately 10% of the middle-aged population and becomes more prevalent with age. It is caused by intermittent and repetitive collapse of the UA during sleep. The main acute physiological consequences of OSA are oxygen desaturation, intrathoracic pressure changes and arousals. OSA is associated with significant cardiovascular morbidity and mortality and is an independent risk factor for CVD. The pathogenesis of CVD in OSA is not completely understood but is likely to be multifactorial, involving a diverse range of closely interrelated and detrimental intermediate mechanisms that predispose patients to atherosclerosis, including oxidative stress, sympa…
A case-control study on risk factors for nuclear, cortical and posterior subcapsular cataract: The Casteldaccia Eye Study
2005
Purpose: To investigate risk factors for nuclear, cortical and posterior subcapsular age-related cataract. Methods: A case-control study was carried out on subjects aged 40 years and older, living in Casteldaccia, Sicily. Twenty-seven potential risk factors were investigated. Nuclear, cortical and posterior subcapsular opacities of the lens were classified according to the Lens Opacities Classification System II. Subjects with advanced lens opacities represented the cases, while an identical number of subjects without or with early cataract, matched for sex and age, were recruited as controls from within the same population. Results: Univariate analysis showed that myopia and iris atrophy w…
Physical activity may not be associated with long‐term risk of dementia and Alzheimer’s disease
2021
Background While it is well established that physical activity is associated with reduced risk of vascular and non‐vascular outcomes as well as mortality, evidence on the association between physical activity and dementia is inconsistent. We aimed to assess the associations of physical activity with the risk of dementia and Alzheimer’s disease (AD). Material and methods We analysed data on 2,394 apparently healthy men with good baseline cognitive function from the prospective population‐based Kuopio Ischaemic Heart Disease study. We assessed habits of physical activity at baseline using a 12‐month leisure‐time physical activity (LTPA) questionnaire. Using Cox regression, we calculated hazar…
Revista electrónica de investigación y evaluación educativa
2014
Resumen tomado de la publicación Título, resumen y palabras clave en inglés y español Se parte de la investigación sobre 'Análisis comparado de las actitudes y valores del profesorado universitario ante la ética profesional', cuyo objetivo es averiguar si el propio profesorado considera que la dimensión ética profesional en general, y la ética profesional docente, en particular, son esenciales para ser un buen profesional de la docencia. Para el estudio preliminar se recogieron respuestas de un total de 81 profesores de las universidades participantes en el estudio (Valencia Estudi General, Complutense de Madrid y Jaume I de Castellón). Se presenta el proceso de elaboración y validación del…
Cardiorespiratory Fitness and the Risk of Serious Ventricular Arrhythmias: A Prospective Cohort Study.
2019
Cardiorespiratory fitness (CRF) is an established risk factor for cardiovascular disease outcomes. However, the relationship of CRF with risk of ventricular arrhythmias (VAs) is unknown. We aimed to assess the prospective association of CRF with the risk of serious VAs. Cardiorespiratory fitness, as measured by maximal oxygen uptake, was assessed using a respiratory gas exchange analyzer in 2299 middle-aged men in the Kuopio Ischemic Heart Disease prospective cohort. We corrected for within-person variability in CRF levels using data from repeated measurements 11 years apart. During median follow-up of 25.3 years (interquartile range, 18.7-27.2 years), 73 serious VAs were recorded. The age-…
Long-term safety of nine systemic medications for psoriasis: A cohort study using the Spanish Registry of Adverse Events for Biological Therapy in De…
2020
Background: Registry studies broadly describing the safety of systemic drugs in psoriasis are needed. Objective: To describe the safety findings of the systemic drugs acitretin, adalimumab, apremilast, cyclosporine, etanercept, infliximab, methotrexate, secukinumab, and ustekinumab used for the treatment of moderate to severe psoriasis in patients included in the Spanish Registry of Adverse Events for Biological Therapy in Dermatological Diseases (BIOBADADERM) Registry. Methods: The incidence rate ratio (IRR) and adjusted IRR (including propensity scores) of identified adverse events for each drug, using methotrexate as reference, were determined by means of a prospective cohort. Results: O…
A sustainable city environment through child safety and mobility:A challenge based on ITS?
2012
Our cities should be designed to accommodate everybody, including children. We will not move toward a more sustainable society unless we accept that children are people with transportation needs, and ‘bussing’ them around, or providing parental limousine services at all times, will not lead to sustainability. Rather, we will need to make our cities walkable for children, at least those above a certain age. Safety has two main aspects, traffic safety and personal safety (risk of assault). Besides being safe, children will also need an urban environment with reasonable mobility, where they themselves can reach destinations with reasonable effort; else they will still need to be driven. This p…
Ultrasound bioeffects in rats: quantification of cellular damage in the fetal liver after pulsed Doppler imaging
2011
Objective To determine whether pulsed Doppler examination of the ductus venosus in rat fetuses could damage exposed tissue. Methods On gestational day 18, the livers of a mean of approximately five fetuses per mother (n = 5.14, SD = 1.6), in a cohort of 35 pregnant female rats, were exposed individually to pulsed Doppler and these were considered the 'exposed group'. The remaining fetuses in each pregnant rat (n = 5.16, SD = 2.1) formed the 'control group'. We tested for 600, 300, 60, 20, 15, 10 and 3 s of exposure of the fetal ductus venosus and the damage was evaluated measuring a cell death index of apoptotic activity at 7 h post-exposure (n = 16). In addition, subgroups of mothers were …
