Decline In Physical Function Research Articles

Adolescents and young adults with sickle cell disease exhibit accelerated aging with elevated T-cell p16INK4a expression.

People living with sickle cell disease (SCD) experience complications indicative of an accelerated aging phenotype typified by early decline in physical function and increased risk for age-related conditions. Cellular senescence, measured by expression of p16INK4a in peripheral T-lymphocytes, is recognized as one of the underlying contributors to organismal aging. To examine if cellular senescence is increased in SCD patients, we cross-sectionally measured and compared expression of p16 mRNA in peripheral blood T lymphocytes in 18 adolescents and young adults with SCD to 27 similarly aged individuals without SCD. Expression of p16 was dramatically higher in individuals with SCD vs. without SCD (10.1 vs. 8.7 log2 p16 units, respectively, p < 0.001) - a gap of 43 years in biological age - consistent with accelerated aging in the SCD population. Race was not associated with the increased p16 expression in the SCD group. These initial results suggest that individuals with SCD have a significantly higher cellular senescence burden which may contribute to premature aging, physiological decline, and excess morbidities. Additional longitudinal assessment and consideration for trials of senolytic therapies among individuals living with SCD and high p16 expression are warranted to improve their health span.

The temporal relation of physical function with cognition and the influence of brain health in the oldest-old.

Introduction Physical function and cognition seem to be interrelated, especially in the oldest-old. However, the temporal order in which they are related and the role of brain health remain uncertain. Methods We included 338 participants (mean age 93.1 years) from two longitudinal cohorts: The UCI 90+ Study and EMIF-AD 90+ Study. We tested the association between physical function (Short Physical Performance Battery, gait speed and handgrip strength) at baseline with cognitive decline (MMSE, memory tests, Animal fluency, Trail Making Test (TMT) A and Digit Span Backward), and the association between cognition at baseline with physical decline (mean follow-up 3.3 years). We also tested whether measures for brain health (hippocampal, white matter lesion and gray matter volume) were related to physical function and cognition, and whether brain health was a common driver of the association between physical function and cognition by adding it as confounder (if applicable). Results Better performance on all physical tests at baseline was associated with less decline on MMSE, memory and TMT A. Conversely, fewer associations were significant but better scores on memory, TMT A and Digit Span Backward were associated with less physical decline. When adding measures for brain health as confounder, all associations stayed significant except for memory with gait speed decline. Discussion In the oldest-old, physical function and cognition are strongly related, independently of brain health. Also, the association between physical function and cognitive decline is more pronounced than the other way around, suggesting a potential for slowing cognitive decline by optimizing physical function.

Implementing palliative and end of life care for people with dementia.

Dementia is characterised by memory loss, behavioural changes and decline of cognitive, social and physical functions and is a life-limiting condition. At the point of diagnosis it is classed as a palliative condition, yet there is limited public and healthcare professional awareness that, once diagnosed, a person will either die of dementia or die with dementia. This article discusses how the recognition and timing of the need for palliative dementia care is pivotal in providing person-centred care. The authors explore factors such as optimal prognostication, advance care planning, staff education and accessing support from palliative and end of life care teams and Admiral Nurses. The authors also use a fictional case study to demonstrate best practice in palliative dementia care.

Efficacy of Radicava® IV (intravenous edaravone) in subjects with differing trajectories of disease progression in amyotrophic lateral sclerosis: Use of a novel statistical approach for post hoc analysis of a pivotal phase 3 clinical trial

IntroductionSubjects with amyotrophic lateral sclerosis (ALS) treated with Radicava® (edaravone) IV (intravenous; Mitsubishi Tanabe Pharma America [MTPA], hereafter “MTPA IV edaravone”) in Study MCI186–19 had a significantly slower physical functional decline vs placebo-treated subjects as measured by the revised ALS Functional Rating Scale (ALSFRS-R) and analyzed by the linear mixed model for repeated measures (MMRM). This Study 19 post hoc analysis of MTPA IV edaravone–treated and placebo-treated subjects evaluated linear and nonlinear latent class mixed models defining trajectories based on identifying the model with the lowest Bayesian information criterion. The best model differentiated 4 nonlinear trajectories in ALS subjects. ALSFRS-R total score in MTPA IV edaravone–treated and placebo-treated subjects was evaluated for these 4 nonlinear latent class trajectory groups. MethodsDisease trajectories of MCI186–19 MTPA IV edaravone–treated or placebo-treated ALS subjects who completed the double-blind period were investigated using latent class analysis (LCA) statistical models to identify potential unique nonlinear ALSFRS-R disease trajectories. ResultsALSFRS-R trajectories revealed 4 unique nonlinear trajectory latent classes per treatment group in MTPA IV edaravone–treated and placebo-treated ALS subjects completing the MCI186–19 double-blind period. Latent classes 2–4 had statistically significant slowing of ALSFRS-R total score decline in the predicted nonlinear trajectories of MTPA IV edaravone–treated vs placebo-treated ALS subjects. ConclusionsThis post hoc analysis suggests MTPA IV edaravone treatment results in slower ALSFRS-R decline vs placebo in most predicted nonlinear trajectories. LCA is a novel approach that may benefit future trial analyses.

Causal linkage of Graves’ disease with aging: Mendelian randomization analysis of telomere length and age-related phenotypes

BackgroundAging is an irreversible progressive decline in physical function. Graves’ disease (GD) is a common cause of hyperthyroidism and is characterized by elevated levels of the thyroid hormone (TH). High TH levels are associated with aging and a shortened lifespan. The causal relationship between GD and aging has yet to be investigated.MethodsWe used genome-wide association study (GWAS) datasets and Mendelian randomization (MR) analysis to explore the causal link between GD and aging. To assess the statistical power of instrumental variables (IVs), F-statistics and R2 were used. MR analysis was conducted using inverse-variance weighting (IVW), MR-Egger, weighted median, and weighted mode. The odds ratio (OR) and 95% CI were calculated to estimate the relative risk of GD to the outcomes. The Cochran Q test, I2, MR-PRESSO test, and MR-Egger regression intercept were calculated using statistical and leave-one-out analyses to test the heterogeneity, horizontal pleiotropy, and stability of the IVs on the outcomes.ResultsF-statistics of the five IVs were greater than 10, and the R2 values ranged from 0.033 to 0.156 (R2 > 0.01). According to the results of the IVW analysis, GD had no causal effect on facial aging (p = 0.189), age-related macular degeneration (p = 0.346), and Alzheimer’s disease (p = 0.479). There was a causal effect of GD on the remaining outcomes: telomere length (TL) (OR = 0.982; 95%CI:0.969–0.994; p = 0.004), senile cataract (OR = 1.031; 95%CI:1.002–1.060; p = 0.033), age-related hearing impairment (OR = 1.009; 95%CI:1.004–1.014; p = 0.001), chronic obstructive pulmonary disease (COPD) (OR = 1.055; 95%CI:1.008–1.103; p = 0.020), and sarcopenia (OR = 1.027; 95%CI:1.009–1.046; p = 0.004).ConclusionsGD accelerates the occurrence of age-related phenotypes including TL, senile cataracts, age-related hearing impairment, COPD, and sarcopenia. In contrast, there are no causal linkages between GD and facial aging, age-related macular degeneration, or Alzheimer’s disease. Further experimental studies could be conducted to elucidate the mechanisms by which GD facilitates aging, which could help slow down the progress of aging.

Association of physical function with masticatory ability and masticatory habits: a cohort study

BackgroundFew studies have evaluated masticatory ability and habits in relation to physical function. This study aimed to investigate the association of physical function with both masticatory ability and masticatory habits.MethodsIn this cohort study, we followed up with 146 community-dwelling older adults aged 65–84 years for 1 year. Physical function domain scores on the Kihon Checklist were used to assess physical function. Masticatory ability was examined using objective measurements and self-administered questionnaires. Data on masticatory habits were obtained using self-administered questionnaires. The Mann–Whitney U test was used to analyze the association between masticatory ability and masticatory habits as exposures; logistic regression analysis was used to analyze the effect of exposure on the outcome.ResultsA relationship was found between objective and subjective masticatory ability; however, no relationship was found between objective masticatory ability and masticatory habits. Furthermore, subjective masticatory ability and masticatory habits appeared to influence physical function 1 year later (odds ratio [OR]: 6.00, 95% confidence interval [CI]: 1.44–25.05; OR: 6.49, 95% CI: 2.45–17.22).ConclusionMasticatory ability and habits may be associated with a decline in physical function after 1 year in community-dwelling older adults. To maintain the physical function of these individuals, early intervention that addresses not only masticatory ability but also masticatory habits is necessary.Graphical

Home-Based Digital Exercise Training Program to Improve Physical Function of Older Sepsis Survivors: Protocol of the HEAL Sepsis Randomized Clinical Trial.

While sepsis, an exaggerated response to infection, can affect people of all age groups, it is more prevalent in middle-aged and older adults. Older adults suffer worse short-term and long-term outcomes than younger patients. Older sepsis survivors are commonly discharged to long-term acute care facilities, where they often die within 1 year. Those who return home from the hospital lose the momentum of physical function improvement after early inpatient rehabilitation, and often face exacerbation of comorbidities and decline in physical function. Additionally, patients who are discharged home often live at distant locations and are not able to commute to rehabilitation centers due to their poor health status. Therefore, remotely delivered exercise interventions tailored to this population hold promise to improve physical function safely and effectively after sepsis. However, this type of intervention has yet to be tested in this population. This study aims to assess the safety, feasibility, and ease of recruitment and retention of participants for a remotely delivered physical activity intervention for improving physical function in middle-aged and older sepsis survivors. The proposed intervention will be delivered through a digital health platform that comprises a patient-facing mobile app and a 12-week physical activity program specifically designed for middle-aged and older sepsis survivors with poor health status who may face challenges participating in traditional out-patient or community-based exercise interventions. This study is ongoing and plans to enroll 40 sepsis survivors aged 55 years and older who will be randomized to either a remotely delivered exercise intervention group or a control group (electronic health diary). Both groups will use a tablet containing the Health in Motion app (Blue Marble Health). The intervention group will receive a clinician-designed personalized avatar-guided home exercise program and reminders while the control group will self-report daily activities using the in-app health diary feature. This study is the first to use a home-based, remotely monitored 12-week exercise program to improve physical function in sepsis survivors. This study will evaluate the safety, feasibility, and efficacy, providing the necessary knowledge to design and calculate power for future larger trials. This study will provide important information for planning a future randomized clinical trial to test the efficacy of a remotely delivered exercise intervention in this high-risk population.

Effects of Neuromuscular Training on Postural Balance and Physical Performance in Older Women: Randomized Controlled Trial.

Background: Aging causes morphological and physiological changes, especially in the musculoskeletal and somatosensory systems, leading to sarcopenia and reduced postural balance, increasing the risk of falls and loss of independence. This study aimed to analyze the effects of a neuromuscular training program on postural balance, physical performance, and muscle strength in older Chilean women. Methods: The double-blind randomized controlled trial included 48 participants aged 65-80 who were divided into three groups: a control group (CG), a multicomponent training group (MCG), and a neuromuscular training group (NMG). Postural balance was assessed using a force platform with open eyes (OE) and closed eyes (CE) conditions, measuring ML velocity, AP velocity, mean radius, and area. Physical performance was evaluated with the Short Physical Performance Battery (SPPB), including static balance, 4-m walking speed, and 5× sit-to-stand chair test. Muscle strength was measured using a hydraulic hand dynamometer to record maximum grip force. Results: Significant time × group interactions in the CE condition were found for mean radius (F = 0.984; p = 0.017; ηp2 = 0.184), AP velocity (F = 10.01; p = 0.001; ηp2 = 0.312), and ML velocity (F = 4.30; p = 0.027; ηp2 = 0.163). Significant pre-post differences in the NMG for mean radius (p < 0.001), AP velocity (p < 0.001), and ML velocity (p = 0.029) were observed, with no significant changes in CG. Significant time × group interactions were also found in the SPPB test score (F = 11.49; p < 0.001; ηp2 = 0.343), gait speed (F = 5.513; p = 0.012; ηp2 = 0.198), and sit-to-stand test (F = 5.731; p = 0.010; ηp2 = 0.206), but not in the balance score (F = 2.099; p = 0.148). Handgrip strength showed no significant interactions (F = 3.216; p = 0.061; ηp2 = 0.127). Conclusions: These findings suggest that neuromuscular training is a promising intervention to mitigate the decline in balance and physical function associated with aging, offering a targeted approach to improve the quality of life in the elderly.

Effect of polypharmacy and potentially inappropriate medications on physical functional decline among older adults with advanced cancer receiving systemic treatment.

Polypharmacy and potentially inappropriate medications (PIM) are common among older adults with advanced cancer, but their association with physical functional outcomes is understudied. This study aimed to estimate the risk of physical functional decline associated with medication measures in older adults with advanced cancer starting a new line of systemic treatment. This secondary analysis of GAP 70+ Trial (PI: Mohile) enrolled patients aged 70+ with advanced cancer, had ≥ 1 geriatric assessment domain impairment and planned to start a new antineoplastic regimen with a high risk of toxicity. Polypharmacy (concurrent use of ≥ 8 medications (meds)) was assessed before initiation of treatment. PIM were categorized using Screening Tool of Older Person's Prescriptions (STOPP) criteria and 2019 Beers criteria. Physical functional outcomes were assessed within 3months of treatment initiation: (1) Activity of Daily Living (ADL) decline: 1-point decrease in ADL score between baseline and 3months; (2) Instrumental ADL (IADL) decline: 1-point decrease in IADL score between baseline and 3months; (3) Short physical performance battery (SPPB) decline, defined as 1-point decrease on SPPB; (4) ≥ 1 falls within 3months of treatment. Separate multivariable, cluster-weighted Generalized Estimating Equations models adjusted for relevant covariates (e.g., age, baseline function/comorbidities). Among 616 participants, mean number of meds was 6 (range 0-24); 28% received ≥ 8 meds. Polypharmacy was associated with increased risk of ADL decline (adjusted risk ratio [aRR], 1.31; 95% CI, 1.00-1.71). Taking ≥ 1 PIM per STOPP was associated with increased risk of IADL decline (aRR, 1.21; 95% CI, 1.04-1.40) and falls (aRR, 1.93; 95% CI, 1.49-2.51). In a large cohort of vulnerable older adults with advanced cancer receiving systemic treatment, polypharmacy and PIM were independently associated with an increased risk of physical functional decline. This emphasizes the need to develop interventions to optimize medication use, intending to improve outcomes in these patients. ClinicalTrials.gov Identifier: NCT02054741. Registered 01-31-2014.

Reliability and validity of balance tests for community-dwelling older adults with musculoskeletal ambulation disability symptom complex

IntroductionPhysical performance-based tests are useful indices for identifying and managing fall risk in community-dwelling older adults. However, measurement errors in these tests have not been examined. This study aimed to clarify the reliability and validity of balance tests in community-dwelling older adults with musculoskeletal ambulation disability symptom complex. MethodsThis cross-sectional study used a test-retest design and included 52 participants from three medical facilities. The participants reported demographic and medical information using a questionnaire. Primary outcomes were the timed up-and-go test, five-times sit-to-stand test, one-leg standing test, and functional reach test results. ResultsSignificant correlations were found between each balance test and fear of falling and between the four balance tests. Each balance test demonstrated discriminant validity with intraclass correlation coefficients (1,1) ≥0.81. The minimal detectable change was 1.4 s, 1.6 s, 3.3 s, and 4.0 cm for the timed up-and-go test, five-time sit-to-stand test, one-leg standing test, and functional reach test, respectively. ConclusionChanges exceeding the minimal detectable change95 in balance tests can be used to judge improvement or decline in physical function, which may inform clinical decision-making. The minimal detectable change95 of balance tests should be used when implementing or modifying fall prevention programs.

Unmodulated 40 Hz Stimulation as a Therapeutic Strategy for Aging: Improvements in Metabolism, Frailty, and Cognitive Function in Senescence-Accelerated Prone 10 Mice.

With aging populations in many countries, including Japan, efforts to mitigate the aging-related decline in physical function have gained importance not only for improving individual quality of life but also for mitigating the effects of this loss of function on society. Impaired glucose tolerance, muscle weakness, and cognitive decline are well-known effects of aging. These interrelated factors can create a vicious cycle because impaired glucose tolerance can accelerate muscle weakness and cognitive decline. Unmodulated 40 Hz (u40Hz) stimulation is imperceptible to the human ear and has been reported to improve cognitive function in humans and mice. However, research on the effects of u40Hz stimulation is still limited. This study aimed to report the effects of u40Hz stimulation on glucose tolerance and muscle strength in senescence-accelerated prone (SAMP)-10 mice, a model of accelerated aging. SAMP-10 mice underwent five weeks of u40Hz stimulation followed by glucose-tolerance tests, cognitive and behavioral assessments, and frailty evaluations. In comparison with the control group, the u40Hz-stimulation group showed mitigation of age-related decline in glucose tolerance, a better frailty index (FI), and notably preserved muscle strength. Microarray analysis of stimulated muscle tissue revealed significant upregulation of β-oxidation genes and genes functioning downstream of peroxisome proliferator-activated receptor gamma, and significant downregulation of clock genes. These findings indicate the beneficial effects of u40Hz stimulation on glucose tolerance, muscle strength, and cognitive function, warranting further research in this area.

Impaired oral health associations with cognitive and motor decline in activities of daily living independence during hospitalization: insights from a post-stroke cohort

PurposeEvidence is scarce on the associations between impaired oral health and cognitive level related to independence in activities of daily living (ADLs) among hospitalized older patients. We aimed to evaluate the associations between baseline oral problems and changes in cognitive level in post-stroke patients. MethodsA retrospective cohort study was conducted, encompassing consecutively hospitalized post-stroke patients. Revised Oral Assessment Guide (ROAG) as a measure of oral health and function was assessed at admission. Primary outcomes included discharge scores for cognitive function assessed by the cognitive domain of the Functional Independence Measure (FIM-cognition) and the corresponding change in FIM-cognition during hospitalization. Another outcome measure was the motor domain of FIM (FIM-motor). Multivariate linear regression analyses were employed to assess the association between baseline ROAG and the designated outcomes, adjusting for potential confounding factors. ResultsData from 955 patients (mean age 73.2 years; 53.6% men) were included in the analysis. The median ROAG was 10 [9, 12], with 811 patients (84.9%) presenting oral problems. After fully adjusting for confounding factors, the ROAG was significantly and negatively associated with FIM-cognition at discharge (β = -0.107, p = 0.031) and FIM-cognition gain (β = -0.093, p = 0.018). Further, the ROAG was independently and negatively associated with FIM-motor at discharge (β = -0.043, p = 0.013) and FIM-motor gain (β = -0.065, p = 0.013). ConclusionOral problems were associated with compromised cognitive levels and a decline in physical function during the hospitalization in post-stroke patients. These results underscore the critical importance of addressing oral health in this patient population.

The Antioxidant and Anti-Inflammatory Properties of Bee Pollen from Acorn (Quercus acutissima Carr.) and Darae (Actinidia arguta).

Aging is a complex biological process characterized by a progressive decline in physical function and an increased risk of age-related chronic diseases. Additionally, oxidative stress is known to cause severe tissue damage and inflammation. Pollens from acorn and darae are extensively produced in Korea. However, the underlying molecular mechanisms of these components under the conditions of inflammation and oxidative stress remain largely unknown. This study aimed to investigate the effect of bee pollen components on lipopolysaccharide (LPS)-induced RAW 264.7 mouse macrophages. This study demonstrates that acorn and darae significantly inhibit the LPS-induced production of inflammatory mediators, such as nitric oxide (NO) and prostaglandin E2 (PGE2), in RAW 264.7 cells. Specifically, bee pollen from acorn reduces NO production by 69.23 ± 0.04% and PGE2 production by 44.16 ± 0.08%, while bee pollen from darae decreases NO production by 78.21 ± 0.06% and PGE2 production by 66.23 ± 0.1%. Furthermore, bee pollen from acorn and darae reduced active oxygen species (ROS) production by 47.01 ± 0.5% and 60 ± 0.9%, respectively. It increased the nuclear potential of nuclear factor erythroid 2-related factor 2 (Nrf2) in LPS-stimulated RAW 264.7 cells. Moreover, treatment with acorn and darae abolished the nuclear potential of nuclear factor κB (NF-κB) and reduced the expression of extracellular signal-associated kinase (ERK) and c-Jun N-terminal kinase (JNK) phosphorylation in LPS-stimulated RAW 264.7 cells. Specifically, acorn decreased NF-κB nuclear potential by 90.01 ± 0.3%, ERK phosphorylation by 76.19 ± 1.1%, and JNK phosphorylation by 57.14 ± 1.2%. Similarly, darae reduced NF-κB nuclear potential by 92.21 ± 0.5%, ERK phosphorylation by 61.11 ± 0.8%, and JNK phosphorylation by 59.72 ± 1.12%. These results suggest that acorn and darae could be potential antioxidants and anti-inflammatory agents.

Opioid-Induced Constipation and Associated Symptoms After Orthopedic Trauma

PurposeOpioid-induced constipation is an adverse effect often experienced among patients taking prescription opioid medication. Despite frequent opioid prescribing after orthopedic injury, there is a dearth of research examining opioid-induced constipation presentations in this population. This analysis examines the frequency of opioid-induced constipation manifestations and association with patient-reported outcomes among participants prescribed opioid medication following orthopedic injury. DesignSecondary analysis of 86 clinical trial participants following orthopedic trauma. MethodsParticipants were assessed 2-weeks postoperatively with the following measures: Patient-Reported Outcome Measurement Information System (PROMIS) Pain Interference, PROMIS Physical Function, past 24-hour average pain intensity captured on the numeric pain rating scale, and the Patient Assessment of Constipation Symptoms (PAC-SYM) questionnaire. Linear regressions examined the association between PAC-SYM scores and both pain intensity and PROMIS T-scores while accounting for injury severity and opioid medication dosage. ResultsMost participants (69%) reported experiencing opioid-induced constipation symptoms and 7% reported moderate to severe symptoms. Compared to those without symptoms, participants reporting opioid-induced constipation symptoms were found to have a 3-point increase in PROMIS Pain Interference (95% Confidence Interval [CI]: 0.28-5.90; p = .032), a 3-point decline in PROMIS Physical Function (95% CI: -6.57 to -0.02; p = .049), and a 1.7-point increase in average pain scores (95% CI: 0.50-3.01; p = .007) at 2-weeks following surgery. ConclusionsOpioid-induced constipation symptoms are common after orthopedic trauma and linked to increased pain interference and pain intensity as well as reduced physical function. Clinical ImplicationsNurse-led assessments of opioid-induced constipation can support the timely delivery of interventions to alleviate symptoms and potentially improve patient-reported outcomes after injury.

Aspiration pneumonia after SARS-CoV-2 Omicron infection frequently induced physical functional decline in Japan.

Introduction. Nursing and healthcare-associated pneumonia (NHCAP) mainly occurs in older people whose physical functions have declined, and it is the most common type of pneumonia in Japan, a super-ageing society. In older people who meet NHCAP criteria, respiratory tract infections are often accompanied by aspiration pneumonia.Gap statement. The SARS-CoV-2 Omicron variant frequently causes aspiration pneumonia and has induced a decline in physical function.Aim. To clarify functional outcomes at 1 year after hospital discharge in SARS-CoV-2 Omicron-related NHCAP cases.Methodology. We compared the functional outcomes between 259 patients with primary SARS-CoV-2 pneumonia and 223 patients with aspiration pneumonia.Results. Functional decline rates for calculating the Barthel index at the time of hospital discharge were higher in the aspiration pneumonia group than the primary SARS-CoV-2 pneumonia group [114 patients (51.6%) vs 70 patients (27.0%), P<0.0001]. Of 114 patients with aspiration pneumonia who had a decline in physical function at the time of hospital discharge, 91 (79.8%) still showed functional decline 1 year later. In contrast, 9.3% of patients had functional decline at 1 year after hospital discharge in the primary SARS-CoV-2 pneumonia group, which was significantly lower than in the aspiration pneumonia group.Conclusions. The Omicron variant showed decreased infectivity in the lungs and was less pathogenic compared with the Delta and former variants. However, physicians should recommend SARS-CoV-2 vaccination and non-pharmaceutical interventions, depending on the presence or absence of applicable criteria for NHCAP, even when the predominant strain is the Omicron variant.

A Healthy Conversation Skills intervention to support changes to physical activity and dietary behaviours in community-dwelling older adults during the COVID-19 pandemic.

Physical activity (PA) and nutrition are important determinants of health in late adulthood. However, low levels of PA and poor nutrition are common in older adults and have become more prevalent during the COVID-19 pandemic. We hypothesised that Healthy Conversation Skills could be used to support health behaviour changes beneficial for health in older adults and thus conducted a study nested within the UK Hertfordshire Cohort Study. Between November 2019 and March 2020, 176 participants were visited at home. A trained researcher administered a questionnaire and undertook anthropometric and physical performance tests. A total of 89 participants were randomised to the control group and received a healthy living leaflet; 87 participants in the intervention group were interviewed using Healthy Conversation Skills at the initial visit with follow-up telephone calls at 1, 3, 6 and 9 months. Follow-up at 1 year by postal questionnaire assessed change in PA and diet. In total, 155 participants (79 control and 76 intervention) completed the baseline and 1-year follow-up. At baseline, median (lower quartile, upper quartile) age (years) was 83.1 (81.5, 85.5) and median PA time (min/day) from walking, cycling and sports was 30.0 (15.0, 60.0). In total, 95% of participants completed the intervention; the total response rate for postal questionnaires was 94%. There were no statistically significant differences in outcomes between the trial arms. In women, there was a tendency for greater increases in diet quality in the intervention group compared to the control group (p = 0.075), while among men, there was a tendency for reduced decline in self-reported physical function in the intervention group compared to the control group (p = 0.081). We have shown that it is viable to utilise Healthy Conversation Skills via telephone to promote healthier lifestyles in older adults. Larger appropriately powered studies to determine the efficacy of such an intervention are now warranted.

The CONVINCE randomized trial found positive effects on quality of life for patients with chronic kidney disease treated with hemodiafiltration

In the CONVINCE trial, the primary analysis demonstrated a survival benefit for patients receiving high-dose hemodiafiltration (HDF) as compared with high-flux hemodialysis (HD). A secondary objective was to evaluate effects on health-related quality of life (HRQoL); assessed in eight domains (physical function, cognitive function, fatigue, sleep disturbance, anxiety, depression, pain interference, social participation) applying instruments from the Patient-Reported Outcome Measurement Information System (PROMIS) before randomization and every three months thereafter. In total 1360 adults with dialysis-dependent chronic kidney disease, eligible to receive high-flux HDF (23 liters or more), were randomized (1:1); 84% response rate to all questionnaires. Both groups reported a continuous deterioration in all HRQoL domains. Overall, raw score changes from baseline were more favorable in the HDF group, resulting in a significant omnibus test after a median observation period of 30 months. Most relevant single raw score differences were reported for cognitive function. Patients receiving HDF reported a decline of -0.95 units (95% confidence interval - 2.23 to +0.34) whereas HD treated patients declined by -3.90 units (-5.28 to - 2.52). A joint model, adjusted for mortality differences, utilizing all quarterly assessments, identified a significantly slower HRQoL decline in physical function, cognitive function, pain interference, and social participation for the HDF group. Their physical health summary score declined -0.46 units/year slower compared to the HD group. Thus, the CONVINCE trial showed a beneficial effect of high-dose hemodiafiltration for survival as well as a moderate positive effect on patients’ quality of life, most pronounced with respect to their cognitive function.

Social Isolation Changes and Long-Term Outcomes Among Older Adults

While the association between cross-sectional measures of social isolation and adverse health outcomes is well established, less is known about the association between changes in social isolation and health outcomes. To assess changes of social isolation and mortality, physical function, cognitive function, cardiovascular disease (CVD), and stroke. In a cohort design, social isolation changes in 4 years and subsequent risk of mortality and other outcomes were assessed using the 13 649 eligible Health and Retirement Study (HRS) respondents from the 2006 to 2020 waves. Data were analyzed from October 11, 2023, to April 26, 2024. The main exposure was the change in social isolation measured by the Steptoe 5-item Social Isolation Index from the initial assessment to a second assessment conducted 4 years later. Participants were classified into decreased isolation, stable, or increased isolation groups, stratified by their baseline isolation status. The primary outcomes were mortality, self-reported dependencies in activities of daily living, Alzheimer disease and Alzheimer disease-related dementia, CVD, and stroke. Dementia, CVD, and stroke were assessed using HRS-linked Medicare records. Incidence rates (IRs) of each group were estimated and a Cox proportional hazards regression model was used, with inverse-probability treatment weighting to adjust for confounders. Among 13 649 participants (mean [SD] age at baseline, 65.3 [9.5] years; 8011 [58.7%] women) isolated at baseline, those with increased isolation had higher mortality (n = 693; IR = 68.19; 95% CI, 60.89-76.36 per 1000 person-years) than those who were stable (n = 1796; IR = 44.02; 95% CI, 40.47-47.88 person-years) or had decreased isolation (n = 2067; IR = 37.77; 95% CI, 34.73-41.09 person-years) isolation. Increased isolation was associated with higher risks of mortality (adjusted hazard ratio [AHR], 1.29; 95% CI, 1.09-1.51), disability (AHR, 1.35; 95% CI, 1.09-1.67), and dementia (AHR, 1.40; 95% CI, 1.02-1.93) compared with stable isolation. Similar findings were observed among socially nonisolated participants at baseline. In this cohort study, increased isolation was associated with elevated risks of mortality, disability, and dementia, irrespective of baseline isolation status. These results underscore the importance of interventions targeting the prevention of increased isolation among older adults to mitigate its adverse effects on mortality, as well as physical and cognitive function decline.

Elderly people experience a natural decline in physical, psychological and social functions due to aging factors. This has an impact on the elderly's ability to fulfill personal hygiene. Elderly people with poor personal hygiene can cause various kinds of health problems, both physical and psychological. Therefore, appropriate education is needed to increase the knowledge and behavior of the elderly regarding good personal hygiene. The aim of this service activity is to increase knowledge about good personal hygiene in the elderly. This service activity was carried out on 30 elderly people at PSBAWEP Harapan Mulya. Activity methods include lectures, discussions and demonstrations such as washing hands, brushing teeth, caring for skin, dressing and grooming oneself. The evaluation results showed that elderly knowledge regarding personal hygiene in the good category increased to 83.33%. This shows that there has been an increase in elderly knowledge regarding personal hygiene after being given education.
