Visit-to-visit blood pressure variability is associated with intrinsic capacity decline: Results from the MAPT Study.

Background: The effectiveness of the body physiological regulatory mechanisms declines in late life, and increased Blood Pressure Variability (BPV) may represent an alteration in cardiovascular homeostatic patterns. Intrinsic Capacity (IC) has been proposed by the World Health Organization as a marker of healthy aging, based on individual's functional abilities and intended at preserving successful aging. We aimed to investigate the association of visit-to-visit BPV with IC decline in a population of community-dwelling older adults.

Earthworms do not increase greenhouse gas emissions (CO and NO) in an ecotron experiment simulating a three-crop rotation system.

Earthworms are known to stimulate soil greenhouse gas (GHG) emissions, but the majority of previous studies have used simplified model systems or lacked continuous high-frequency measurements. To address this, we conducted a 2-year study using large lysimeters (5 m area and 1.5 m soil depth) in an ecotron facility, continuously measuring ecosystem-level CO, NO, and HO fluxes.

Associations Between Blood Nutritional Biomarkers and Cerebral Amyloid-β: Insights From the COGFRAIL Cohort Study.

Understanding the relationship between blood nutrients and neurodegeneration could contribute to devising strategies for preventing Alzheimer's disease. We investigated the associations between fatty acids, vitamins D, B6, B12, folate, homocysteine, and the cerebral load of amyloid β (Aβ). This cross-sectional study included 177 older adults (70-96 years, 65% female) with objective cognitive impairment, prefrail, or frail.

Orthostatic hypotension and orthostatic hypertension are both associated with lower cognitive function: The S.AGES cohort.

Background: Blood pressure (BP) postural changes, both orthostatic hypotension (OHYPO) and orthostatic hypertension (OHYPER) are common in older adults. Few studies have investigated their association with cognition, particularly for OHYPER, an emerging cardiovascular risk factor. We aimed to assess the association between OHYPO, OHYPER and cognition in non-institutionalized older subjects.

Biomarkers of mitochondrial dysfunction and inflammaging in older adults and blood pressure variability.

Most physiopathological mechanisms underlying blood pressure variability (BPV) are implicated in aging. Vascular aging is associated with chronic low-grade inflammation occurring in late life, known as "inflammaging" and the hallmark "mitochondrial dysfunction" due to age-related stress. We aimed to determine whether plasma levels of the pleiotropic stress-related mitokine growth/differentiation factor 15 (GDF-15) and two inflammatory biomarkers, interleukin 6 (IL-6) and tumor necrosis factor receptor 1 (TNFR-1), are associated with visit-to-visit BPV in a population of community-dwelling older adults.

Objectives: The aim was to analyze the cross-sectional and retrospective longitudinal associations between erythrocyte ω-3 index and cognition, brain imaging, and biomarkers among older adults.

Methods: A total of 832 Alzheimer's Disease Neuroimaging Initiative 3 (ADNI-3) participants, with a mean (SD) age of 74.

Blood pressure variability: A potential marker of aging.

Aging is characterized by alterations in neuro-cardiovascular regulatory mechanisms, leading to impaired physiological variability patterns. Repeated evidence has shown that increased Blood Pressure Variability (BPV) is associated with organ damage and exerts independent predictive value on several health outcomes: cardiovascular events, neurocognitive impairment, metabolic disorders and typical geriatric syndromes such as sarcopenia and frailty. Accordingly, it may constitute the epiphenomenon of the alterations in homeostatic mechanisms, typical of late life.

Methods: We studied 2,653 participants from the Coronary Artery Risk Development in Young Adults (CARDIA) study (57% women, 46% Black). Echocardiograms were obtained at year 5, 25, and 30 visits (participant mean age 30, 50, and 55 years) to assess left ventricular (LV) mass (LVM), LV systolic function with LV ejection fraction (LVEF), and LV diastolic function with left atrial volume (LAV) and early peak mitral velocity (E)/early peak mitral annular velocity (e') ratio.

Potentially Inappropriate Medication Prescribing Detected by Computer Algorithm among Older Patients: Results from the MAPT Study.

(1) Background: Some medications may be dangerous for older patients. Potentially inappropriate medication prescribing (PIP) among older patients represents a significant cause of morbidity. The aim of this study was to create an algorithm to detect PIP in a geriatric database (Multidomain Alzheimer Preventive Trial (MAPT) study), and then to assess the algorithm construct validity by comparing the prevalence of PIP and associated factors with literature data.

Impact of pharmacist-led interventions on patient care in ambulatory care settings: A systematic review.

Background: In an era of rapid evolution in healthcare delivery, major changes have occurred within the profession of pharmacist. Because the impact of pharmacist-led interventions in the hospital setting has been well-studied and showed mixed findings on drug-related readmissions, all-cause emergency department visits and mortality, this systematic review focused on services provided by pharmacists in the community or ambulatory care setting without being limited to a specific intervention or outcome.

Objective: To investigate the impact of pharmacist-led interventions, categorised into clinical medication review (CMR), adherence review (AR), and prescription review (PR) on various aspects of patient care (clinical, behavioural, economic and humanistic outcomes in ambulatory care setting) and understand which particular intervention makes the greatest contribution.

Visit-to-Visit Blood Pressure Variability and Incident Frailty in Older Adults.

This study aimed to determine whether visit-to-visit blood pressure (BP) variability (BPV) is associated with incident frailty. We included 1 394 nonfrail community-dwelling participants aged ≥70 years from the Multidomain Alzheimer Preventive Trial (MAPT) who underwent repeated clinical examinations, including BP and frailty, over a 5-year follow-up period. Systolic BPV (SBPV), diastolic BPV (DBPV), mean arterial pressure variability (MAPV), and pulse pressure variability (PPV) were evaluated using standard deviation (SD), coefficient of variation (CV), average real variability, successive variation, variation independent of mean, and residual SD.
