Knee osteoarthritis and risk of hypertension: A longitudinal cohort study
2018
Whilst previous research has indicated an association between osteoarthritis and cardiovascular disease, it remains unclear whether people with osteoarthritis are at greater risk of developing hypertension. The aim of this study was to answer this uncertainity. We used the data of the Osteoarhritis Iniative, an ongoing public and private longitudinal study including people at higher risk of osteoarthritis or having knee osteoarthritis. Knee osteoarthritis was defined through radiological and clinical assessment. Incident hypertension was defined as a systolic blood pressure >140 mmHg and/or a diastolic value >90 mmHg. Multivariate Cox’s regression analyses were constructed where the p…
Concerning mistreatment of older people: clinical and ethical thoughts based on a study of known cases.
2006
International audience; Following a report by the Health Ministry recommending a greater implication of general practitioners (GP) in the diagnosis and care of mistreated older people, we wanted to evaluate what was actually their role in this matter. A study was made of files of mistreated older persons referred to the social services in a Parisian suburb. For each file, we noted who raised the first suspicions of mistreatment, who diagnosed it, what happened next, and what precisely the GP's role was. Out of 600 files, we found 12 cases, concerning 14 persons (two couples). Although all the patients had health problems requiring frequent consultations with their GP, none of these situatio…
Muscular performances at the ankle joint in young and elderly men.
2005
The effect of aging on mechanical and electromyographic characteristics of ankle joint muscles was investigated in 11 young (mean age 24 years) and 12 elderly (mean age 77 years) males. Maximal and submaximal isometric voluntary torques were measured during ankle plantarflexion and dorsiflexion. Electromyographic activities of triceps surae and tibialis anterior muscles were recorded. The elderly group developed equal maximal dorsiflexion torques (42 vs 45 N.m, p >.05), but in plantarflexion, the elderly group was weaker (80 vs 132 N.m, p <.001) and presented a decreased twitch amplitude (11 vs 16 N.m) and lower coactivation (8% vs 15%) than that of the young adults. We established a linear…
Perceived stress and depression amongst older stroke patients: Sense of coherence as a mediator?
2018
Abstract Objective This study aimed to explore the relationship between perceived stress, sense of coherence, and depression among older stroke patients. Methods A demographic questionnaire, the Perceived Stress Scale (PSS), the Sense of Coherence Scale (SOC) and the Center for Epidemiologic Studies Depression Scale (CES-D) were distributed to 3000 older stroke patients from Neurology wards in six large general hospitals, and 2907 individuals completed the survey. Data analysis consisted of correlation, multiple linear regression, and structural equation modeling. Results The total score of the SOC and perceived stress showed a negative correlation (r = −0.80, P ＜ 0.01), the total SOC of co…
External validity of randomized controlled trials in older adults, a systematic review.
2017
Background To critically assess the external validity of randomized controlled trials (RCTs) it is important to know what older adults have been enrolled in the trials. The aim of this systematic review is to study what proportion of trials specifically designed for older patients report on somatic status, physical and mental functioning, social environment and frailty in the patient characteristics. Methods PubMed was searched for articles published in 2012 and only RCTs were included. Articles were further excluded if not conducted with humans or only secondary analyses were reported. A random sample of 10% was drawn. The current review analyzed this random sample and further selected tri…
Polyphenol-Rich Foods in the Mediterranean Diet are Associated with Better Cognitive Function in Elderly Subjects at High Cardiovascular Risk
2012
Brain oxidative processes play a major role in age-related cognitive decline, thus consumption of antioxidant-rich foods might help preserve cognition. Our aim was to assess whether consumption of antioxidant-rich foods in the Mediterranean diet relates to cognitive function in the elderly. In asymptomatic subjects at high cardiovascular risk (n = 447; 52% women; age 55-80 y) enrolled in the PREDIMED study, a primary prevention dietary-intervention trial, we assessed food intake and cardiovascular risk profile, determined apolipoprotein E genotype, and used neuropsychological tests to evaluate cognitive function. We also measured urinary polyphenols as an objective biomarker of intake. Asso…
Psychological and physical dimensions explaining life satisfaction among the elderly: A structural model examination
2007
The aim of the present paper is to analyze the effects of psychological well-being, physical functioning and socio-demographic factors on life satisfaction. Both a bivariate and a multivariate level of analyses have been used. Finally, a structural model explaining life satisfaction has been developed and validated. With respect to bivariate relations, there was evidence of significant positive relations between psychological well-being dimensions and life satisfaction and between physical conditions and life satisfaction as well. Also, as age increased there was a slow decrease in life satisfaction. Educational level was positively related to life satisfaction. A structural model gave valu…
Sicilian centenarian offspring are more resistant to immune ageing
2018
Background: Immunosenescence constitutes a major indirect cause of morbidity and mortality in the elderly. Previous analysis of immune signatures in a cohort of centenarian offspring showed an intermediate immunophenotype between age-matched and younger controls. Aims: To confirm and extend the previous studies performing further phenotypical analysis in centenarian offspring and controls. Methods: Analysis of Treg cells, γδ T cells, mucosal-associated invariant T cells, and senescent immune T cells was performed in centenarian offspring and controls. Results: We report significant differences between elderly and centenarian offspring in most of the studied subsets, showing that centenarian…
Is the Mean Blood Leukocyte Telomere Length a Predictor for Sporadic Thoracic Aortic Aneurysm? Data from a Preliminary Study
2012
Telomeres have been postulated as a universal clock that shortens in parallel with cellular aging. They are specialized DNA-protein structures at the ends of chromosome with remarkable functions--preventing their recognition as double-stranded DNA breaks, protecting their recombination and degradation, and avoiding a DNA damage cellular response. Telomere shortening is currently considered the best aging marker, but is also a predictor for age-related diseases, including cardiovascular diseases. Biological age clearly seems to be a better predictor of vascular risk rather than chronological age. This concept is supported by key assumptions that peripheral blood leukocyte telomere content ac…
CHCH10 mutations in an Italian cohort of familial and sporadic amyotrophic lateral sclerosis patients
2015
Mutations in CHCHD10 have recently been described as a cause of frontotemporal dementia (FTD) comorbid with amyotrophic lateral sclerosis (ALS). The aim of this study was to assess the frequency and clinical characteristics of CHCHD10 mutations in Italian patients diagnosed with familial (n= 64) and apparently sporadic ALS (n= 224). Three apparently sporadic patients were found to carry c.100C>T (p.Pro34Ser) heterozygous variant in the exon 2 of CHCHD10. This mutation had been previously described in 2 unrelated French patients with FTD-ALS. However, our patients had a typical ALS, without evidence of FTD, cerebellar or extrapyramidal signs, or sensorineural deficits. We confirm that CHC…
