Profound T-cell lymphopenia is the hallmark of severe coronavirus disease 2019 (COVID-19). T-cell proliferation is telomere length (TL) dependent and telomeres shorten with age. Older COVID-19 patients, we hypothesize, are, therefore, at a higher risk of having TL-dependent lymphopenia.

Background: Lymphopenia due to a plummeting T-cell count is a major feature of severe COVID-19. T-cell proliferation is telomere length (TL)-dependent and TL shortens with age. Older persons are disproportionally affected by severe COVID-19, and we hypothesized that those with short TL have less capacity to mount an adequate T-cell proliferative response to SARS-CoV-2.

The antiphospholipid syndrome is a thrombophilia characterized by the combination of arterial and/or venous thrombotic events or obstetric clinical events, associated with persistent presence of antiphospholipid antibodies. In this syndrome, thromboses may affect all of the vascular tree, renal damage is frequently associated with a specific antiphospholipid syndrome nephropathy. We propose in this review to provide updated recommendations on the management of antiphospholipid syndrome in nephrology.

Article Synopsis
  • The study investigates the use of twelve validated tests and scales for elderly care among general practitioners, exploring their effectiveness and the challenges faced by doctors in utilizing these tools during consultations.
  • Results show that while 85.5% of trained doctors use these tests frequently, a significant portion (35%) never employs them, citing time constraints and inadequate training as major barriers.
  • Despite recognizing the potential benefits of these assessment tools for managing geriatric conditions, over half of the practitioners believe they are unsuitable for their practices, highlighting a gap in appropriate resources tailored to their needs.

Background: Carotid-femoral pulse-wave velocity (PWV) provides a comprehensive noninvasive indication of arterial stiffness, and is now established as a strong marker of cardiovascular disease (CVD). The correlation between peripheral blood pressure (BP) and PWV and their respective influences on mortality have been poorly studied in the elderly. Our objective was to analyze this correlation in nursing-home residents over 80 years of age, with the view that the results of this could ultimately be helpful in implementing strategies for the diagnosis and long-term follow-up of CVD and mortality in the very elderly population.

Undernutrition is common in elderly people living at home. A loss of autonomy can lead them to use home help services, such as home delivered meals. However this solution is not always effective and having meals brought to the home seems to aggravate their isolation, as the results of a survey of twenty people showed.

Objectives: The aim of the longitudinal PARTAGE study was to determine the predictive value of blood pressure (BP) and pulse pressure amplification, a marker of arterial function, for overall mortality (primary endpoint) and major cardiovascular (CV) events, in subjects older than 80 years of age living in a nursing home.

Background: Assessment of pulse indexes may be important in the evaluation of the CV risk in very elderly frail subjects.

Methods: A total of 1,126 subjects (874 women) who were living in French and Italian nursing homes were enrolled (mean age, 88 ± 5 years).

Background: The continual monitoring of population health-related quality of life (HRQoL) with validated instruments helps public health agencies assess, protect, and promote population health. This study aimed to determine norms for the French adolescent and adult general population for the Duke Health Profile (DUKE) questionnaire in a large representative community sample.

Methods: We randomly selected 17,733 French people aged 12 to 75 years old in 2 steps, by households and individuals, from the National Health Barometer 2005, a periodic population study by the French National Institute for Prevention and Health Education.

Almost all the epidemiological studies that aimed to answer the question of the relationship between heart rate and all-cause or cardiovascular morbidity and mortality reported that a high heart rate was associated with a higher risk of all-cause mortality and cardiovascular events. This relationship has been found to be generally stronger in men than among women. The increase in the cardiovascular risk, associated with the acceleration of heart rate, was comparable to the increase in risk observed with high blood pressure.

Activation of the AT1 angiotensin II (Ang II) receptors has various effects including vasoconstriction, hypertrophy, and possibly hyperplasia of vascular smooth muscle cells and cardiomyocytes and increase in extracellular collagen matrix synthesis. These actions lead to the development of cardiovascular hypertrophy and fibrosis, as well as arterial stiffness, which are some key factors in the development of the cardiovascular and renal complications. In clinical studies, it has been shown that renin-angiotensin blockade has direct and specific implications in the evolution of heart failure, coronary disease, stroke, and hypertensive and diabetic renal disease.

Carotid-femoral pulse wave velocity (PWV) is considered the gold-standard measurement of arterial stiffness. Obesity, however, can render inaccurate the measurement of PWV by external noninvasive devices. Phase-contrast MRI allows the determination of aortic PWV in multiple aortic locations with intra-arterial distance measurements, as well as the assessment of aortic mechanical properties.

An acquired resistance to activated protein C (APC) has been demonstrated in patients with antiphospholipid antibodies (aPL). Recent studies report interactions between beta2 glycoprotein I (beta2GPI) and prothrombin-binding antibodies and the protein C system. Some aPL in patients recognize one or more conformational epitopes shared by beta2GPI and catalytic domains of APC.

Interference of antiphospholipid antibodies (aPL) with coagulation was investigated in 40 aPL-patients (24 with thrombosis) using thrombography. Impairment of the activated protein C anticoagulant pathway was partially offset by the genuine anticoagulant effect. The net result, a procoagulant phenotype, was associated with a 7-fold increased risk of thrombosis in aPL-patients.
