The impact of dietary acid load on super-agers with exceptional cognitive abilities: a propensity score analysis of national health and nutrition examination survey (NHANES) 2011-2014.

OBJECTIVES: 'Super-agers,' individuals over 80 with memory abilities comparable to those 20-30 years younger. The relationship between super-agers and dietary acid load (DAL) is an area that warrants further investigation. We aim to examine the link between DAL and super-agers and assess DAL's effects on cognitive functions across different age groups and cognitive domains. DESIGN: Employing a cross-sectional analysis of the 2011-2014 National Health and Nutrition Examination Survey (NHANES) data, we utilized propensity score analysis and multivariate-adjusted regression to mitigate confounding factors. SETTING: Older adults aged 60 and above in the United States. PARTICIPANTS: Our primary analysis encompassed 985 older adults, supplemented by a sensitivity analysis with 2,522 participants. MEASUREMENTS: DAL was assessed through potential renal acid load (PRAL), estimated net acid excretion (NAEes), and net endogenous acid production (NEAP) indices. RESULTS: Super-agers demonstrate a preference for alkaline diets, shown by their lower DAL indices. After inverse probability of treatment weighting (IPTW), multivariate-adjusted logistic regression reveals that each unit reduction in NAEes and PRAL increases the chances of being a super-ager by 3.9% and 3.0%, respectively. The DAL's impact on cognitive function becomes more pronounced with age. Lower PRAL and NAEes scores are significantly linked to higher situational memory and overall cognitive performance scores in those over 70, with these effects being even more pronounced in participants over 80. CONCLUSION: This research pioneers in demonstrating that super-agers prefer an alkaline diet, highlighting the potential role of alkaline diet in countering cognitive decline associated with aging.

The Balance Between Intensive and Palliative Care in an Anti-melanoma Differentiation-Associated Gene 5 (MDA5) Antibody-Positive Acute Interstitial Pneumonia in a Nonagenarian: A Case Report.

This case report details the management of anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive acute interstitial pneumonia in a 93-year-old man, a condition characterized by rapid progression and high mortality. Despite the grim prognosis typically associated with this disease, especially in elderly patients, the subject of this report survived beyond the expected timeframe, illustrating the effectiveness of prompt and aggressive treatment strategies. Initially presenting with dyspnea, the patient's diagnostic process was challenging due to the absence of dermatomyositis (DM)-specific skin manifestations. However, early suspicion led to the identification of anti-MDA5 antibodies, confirming the diagnosis. The treatment regimen initiated with corticosteroid pulses, cyclophosphamide, tacrolimus, and high-dose gamma globulin therapy significantly improved the patient's respiratory conditions, giving the patient and his family time to decide on their palliative care. This approach underlines the importance of early diagnosis and the implementation of comprehensive treatment strategies in managing anti-MDA5 antibody-positive interstitial pneumonia. In this case, the successful outcome adds valuable insights into the potential for extending survival and enhancing the quality of life in elderly patients with this severe autoimmune condition, emphasizing the need for a proactive and aggressive approach to treatment.

Factors associated with loneliness among individuals aged 80 years and over: Findings derived from the nationally representative "Old Age in Germany (D80+)" study.

OBJECTIVES: To clarify the factors associated with loneliness in individuals aged 80 years and older in Germany (also stratified by sex). METHODS: Data from the nationally representative "Old Age in Germany (D80+)" were employed. The analytic sample equaled 10,031 individuals. The D80+ study included community-dwelling and institutionalized individuals ≥ 80 years in Germany. Multiple linear regressions were used (with sociodemographic and health-related explanatory factors). The collection of data occurred between November 2020 and April 2021 (written questionnaire). RESULTS: Higher loneliness was significantly associated with not being married (e.g., widowed compared to being married, ß=0.37, p<.001), being institutionalized (ß=0.33, p<.001), low education (high education compared to low education, ß=-0.07, p<.01), a higher number of chronic conditions (ß=0.02, p<.001), poor self-rated health (ß=-0.19, p<.001) and greater functional impairment (ß=0.15, p<.001). Sex-stratified regressions produced comparable results. However, low education was only associated with higher loneliness among men, but not women (with significant interaction: education x sex). CONCLUSION: Several sociodemographic and health-related factors can contribute to loneliness among the oldest old in Germany, with sex-specific associations between education and loneliness. Overall, such knowledge can aid to address individuals with higher loneliness levels.

A case report of a 5 mm port site hernia that occurred at the drain insertion site after laparoscopic right nephrectomy.

A 5 mm port site hernia during laparoscopic surgery is rarer than a 12 mm port site hernia. Here, we report the case of a 5 mm port site hernia in an 85-year-old woman who underwent long-term steroid therapy and laparoscopic right nephrectomy. There was also a hernia at the port site where the drain was placed. Due to the 5 mm port at the drain removal site, fascial suturing was impossible after removal of the drain, and countermeasures were difficult. However, we believe that patients at a higher risk of port need suturing wound patients like this and should be carefully observed.

Self-rated health in old age, related factors and survival: A 20-Year longitudinal study within the Silver-MONICA cohort.

INTRODUCTION: Self-rated health (SRH) offers insights into the evolving health demographics of an ageing population. AIM: To assess change in SRH from old age to very old age and their associations with health and well-being factors, and to investigate the association between SRH and survival. METHODS: All participants in the MONICA 1999 re-examination born before 1940 (n = 1595) were included in the Silver-MONICA baseline cohort. The Silver-MONICA follow-up started in 2016 included participants in the Silver-MONICA baseline cohort aged 80 years or older. Data on SRH was available for 1561 participants at baseline with 446 of them also participating in the follow-up. The follow-up examination included a wide variety of measurements and tests. FINDINGS: Most participants rated their health as "Quite good" (54.5 %) at baseline. Over the study period, 42.6 % had stable SRH, 40.6 % had declined, and 16.8 % had improved. Changes in SRH were at follow-up significantly associated with age, pain, nutrition, cognition, walking aid use, self-paced gait speed, lower extremity strength, independence in activities of daily living, weekly physical exercise, outdoor activity, participation in organized activities, visiting others, morale, and depressive symptoms. SRH at baseline was significantly associated with survival (p < 0.05). CONCLUSION: This study demonstrates associations between changes in SRH and a multitude of health- and wellbeing-related factors, as well as a relation between survival and SRH, accentuating their relevance within the ageing population.

Preventive interventions to improve older people's health outcomes: systematic review and meta-analysis.

BACKGROUND: Systematic reviews of preventive, non-disease-specific primary care trials for older people often report effects according to what is thought to be the intervention's active ingredient. AIM: To examine the effectiveness of preventive primary care interventions for older people and to identify common components that contribute to intervention success. DESIGN AND SETTING: A systematic review and meta-analysis of 18 randomised controlled trials (RCTs) published in 22 publications from 2009 to 2019. METHOD: A search was conducted in PubMed, MEDLINE, Embase, Web of Science, CENTRAL, CINAHL, and the Cochrane Library. Inclusion criteria were: sample mainly aged ≥65 years; delivered in primary care; and non-disease-specific interventions. Exclusion criteria were: non-RCTs; primarily pharmacological or psychological interventions; and where outcomes of interest were not reported. Risk of bias was assessed using the original Cochrane tool. Outcomes examined were healthcare use including admissions to hospital and aged residential care (ARC), and patient-reported outcomes including activities of daily living (ADLs) and self-rated health (SRH). RESULTS: Many studies had a mix of patient-, provider-, and practice-focused intervention components (13 of 18 studies). Studies included in the review had low-to-moderate risk of bias. Interventions had no overall benefit to healthcare use (including admissions to hospital and ARC) but higher basic ADL scores were observed (standardised mean difference [SMD] 0.21, 95% confidence interval [CI] = 0.01 to 0.40) and higher odds of reporting positive SRH (odds ratio [OR] 1.17, 95% CI = 1.01 to 1.37). When intervention effects were examined by components, better patient-reported outcomes were observed in studies that changed the care setting (SMD for basic ADLs 0.21, 95% CI = 0.01 to 0.40; OR for positive SRH 1.17, 95% CI = 1.01 to 1.37), included educational components for health professionals (SMD for basic ADLs 0.21, 95% CI = 0.01 to 0.40; OR for positive SRH 1.27, 95% CI = 1.05 to 1.55), and provided patient education (SMD for basic ADLs 0.28, 95% CI = 0.09 to 0.48). Additionally, admissions to hospital in intervention participants were fewer by 23% in studies that changed the care setting (incidence rate ratio [IRR] 0.77, 95% CI = 0.63 to 0.95) and by 26% in studies that provided patient education (IRR 0.74, 95% CI = 0.56 to 0.97). CONCLUSION: Preventive primary care interventions are beneficial to older people's functional ability and SRH but not other outcomes. To improve primary care for older people, future programmes should consider delivering care in alternative settings, for example, home visits and phone contacts, and providing education to patients and health professionals as these may contribute to positive outcomes.

Association between baseline office blood pressure level and the incidence and development of long-term frailty in the community-dwelling very elderly with hypertension.

Frailty is the most important risk factor causing disability in the elderly. Hypertension is one of the most common chronic diseases in the elderly and is closely related to frailty, but there is still controversy about the association between blood pressure and frailty. To explore the association between baseline blood pressure level and the incident and development of long-term frailty in the community-dwelling very elderly (i.e., over 80 years old [1]) with hypertension, in order to provide a basis for scientific blood pressure management of very elderly hypertension. In this study, very elderly hypertensive patients who received comprehensive geriatric assessment from January to June 2019 and with complete data were included, and follow-up was conducted from January 1 to February 14, 2023. A total of 330 very elderly individuals with hypertension were enrolled in this study. FRAIL scale was used to evaluate frailty. Binomial logistic regression analysis was used to calculate the OR and 95%CI between baseline systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP) levels and long-term incident and development of frailty. The dose-response relationship between baseline office SBP, DBP or PP levels and incident frailty and its development was analyzed by Generalized Additive Model (GAM) using smooth curve fitting and threshold effect analysis. Smooth curve fitting and threshold effect analysis showed that the relationship between baseline office SBP level and incident frailty was U-shaped, with the nadir of the U-shaped curve at 135 mmHg after adjustment. Baseline office SBP, PP level and development frailty was U-shaped and the nadir was 140 mmHg and 77 mmHg. In the community-dwelling very elderly with hypertension, baseline office SBP level had a relationship with long-term incident frailty and its development and PP level had a relationship with long-term development of frailty.

Longitudinal trajectories of cognitive decline and cerebral blood flow abnormalities in octogenarian men with normal global cognition.

Aims: Cognitive and perfusion changes have been previously observed in older men with Mini Mental State Examination scores>24 points. We aimed to investigate time change in cognitive domains in a cohort of non-demented men between age 68 and 82, and how they are expressed in regional defects estimated by Cerebral Blood Flow (rCBF). Methods: 103 men at age 81 with MMSE scores >24 (mean 28.4 ± 1.7), no dementia or stroke, were examined with the same cognitive test battery at age 68 and age 81: Synonyms (SRB-1), Block design (SRB-3), Paired Associates, Digit Symbol Substitution and Benton Visual Retention test. rCBF was estimated using 99mTc-HMPAO SPECT at age 82. Results: Between ages 68 and 82 we observed a relative decline (Δ%) of cognitive test scores: SRB-3 and Benton tests, -33.7 % (SD 16,8) and -25.8 % (SD 23.9) respectively, followed by Digit Symbol test: -22,6 % (SD 15,6). The cluster of men (46 %) could be detected, grouped on the largest test score decline and highest overall test predictors' importance in decreasing order: Δ% SRB-3, Δ% Paired Associates, Δ% Digit Symbol, Δ% Benton VR and Δ% SRB-1. Compared to the cluster with stable cognitive functions, it expressed lower rCBF in frontal and parietal lobes, and in subcortical areas. Conclusion: Nearly half of the studied, community-dwelling cohort of non-demented, octogenarian men with MMSE > 24, had a combination of decreasing visuospatial ability and episodic memory during preceding years, expressed by widespread rCBF changes in fronto-subcortical areas.

Prevalence and population characteristics associated with frailty in a rural low socioeconomic area in Denmark: the Lolland-Falster Health Study.

BACKGROUND: Frailty is a major geriatric syndrome that predicts increased vulnerability to minor stressor events and adverse outcomes such as falls, fractures, disability and death. The prevalence of frailty among individuals above the age of 65 varies widely with an overall weighted prevalence of 10.7%. OBJECTIVES: The purpose of this study was to examine the prevalence of prefrailty and frailty in community-dwelling older adults from the regions of Lolland-Falster, which is one of the most socioeconomically disadvantaged areas of Denmark with lower income and lower life expectancy compared with the general Danish population. Moreover, the objective was to find selected individual characteristics associated with frailty. DESIGN: An observational, cross-sectional registry-based population study with data from the regions of Lolland-Falster collected between February 2016 and February 2020. RESULTS: The study included 19 000 individuals. There were 10 154 above the age of 50 included for analysis. Prevalence of frailty in the age group of 50-64 years was 4.7% and 8.7% in the age group of 65 years and above.The study demonstrates associations between frailty and high age, female gender, low education level, low income, smoking, living alone, frequency of seeing one's children and getting help when needed. These associations are comparable with findings from other studies. CONCLUSION: The syndrome of frailty consists of not only physiological and medical issues but also education, life conditions such as living alone and living in poverty and how you evaluate your own health.

Validity and test-retest reliability of the Swedish version of the Geriatric Depression Scale among very old adults.

BACKGROUND: The Geriatric Depression Scale (GDS) has shown good validity and reliability, but few studies have examined the GDS among very old adults or the Swedish translation. OBJECTIVES: Evaluate the validity and reliability of the Swedish version of GDS-15 among very old adults. METHODS: In the Umeå85 + /GErontological Regional DAtabase (GERDA) study, 387 participants were assessed with both the GDS-15 and the Montgomery-Åsberg Depression Rating Scale (MADRS). The mean age was 91 years. Concurrent validity between the scales was calculated using Spearman's correlation. We used the Diagnostic and Statistical Manual of Mental Disorders (DSM) V symptom criteria for depression based on MADRS item scores to define depression. We calculated the Area Under the Curve (AUC) and found an optimal cut-off. A convenience sample with 60 individuals was used to calculate test-retest reliability with Cohen's kappa and Intraclass Correlation Coefficient (ICC). RESULTS: Spearman's correlation coefficients between total scores for GDS-15 and MADRS were 0.60. Cronbach's alpha for the whole scale was 0.73. The AUC was 0.90 for distinguishing major depression, and the recommended cut-off of ≥ 5 showed a sensitivity of 95.2% and specificity of 65.8%. The test-retest showed that Cohen's kappa was substantial (0.71) and the ICC was excellent (0.95). CONCLUSIONS: The Swedish version of the GDS-15 showed good validity and reliability among very old adults. The generally recommended cut-off of ≥ 5 seems reasonable to use with the Swedish version and among very old adults.

Exploring the meaning of a good life for older widows with extensive need of care: a qualitative in-home interview study.

INTRODUCTION: Studies of older women's life transitions is rare but gains relevance as the aging population, with older women as the majority, expands. PURPOSE: To explore the meaning of a good life for older widows with extensive home care needs. MATERIALS AND METHODS: Semi-structured interviews were carried out with eleven women, aged 80 and over (82-95 years, mean 90) residing at home with extensive care needs (≥4 daily sessions, averaging 2.5-6 hours, mean 3). Data were analysed by reflexive thematic analysis. RESULTS: The theme "This Day in My Home, the frame of my life" reflects the women's experience of a good life. A good day imbued them with hope, trust and security, carrying them forward with the assurance that night would usher in a new day. However, there were moments when life was merely about navigating daily challenges. During such days, the women felt trapped in time, unsafe and lonely. CONCLUSION: A day at home may seem static, yet it mirrors life's dynamism, evolving with shifting circumstances. Older widows navigate challenges while maintaining their sense of self, independence, and connection to home. These findings have implications for aged care, recognizing the multifaceted aspects of life and the centrality of home.

Brain health measurement: a scoping review.

OBJECTIVES: Preservation of brain health is an urgent priority for the world's ageing population. The evidence base for brain health optimisation strategies is rapidly expanding, but clear recommendations have been limited by heterogeneity in measurement of brain health outcomes. We performed a scoping review to systematically evaluate brain health measurement in the scientific literature to date, informing development of a core outcome set. DESIGN: Scoping review. DATA SOURCES: Medline, APA PsycArticles and Embase were searched through until 25 January 2023. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies were included if they described brain health evaluation methods in sufficient detail in human adults and were in English language. DATA EXTRACTION AND SYNTHESIS: Two reviewers independently screened titles, abstracts and full texts for inclusion and extracted data using Covidence software. RESULTS: From 6987 articles identified by the search, 727 studies met inclusion criteria. Study publication increased by 22 times in the last decade. Cohort study was the most common study design (n=609, 84%). 479 unique methods of measuring brain health were identified, comprising imaging, cognitive, mental health, biological and clinical categories. Seven of the top 10 most frequently used brain health measurement methods were imaging based, including structural imaging of grey matter and hippocampal volumes and white matter hyperintensities. Cognitive tests such as the trail making test accounted for 286 (59.7%) of all brain health measurement methods. CONCLUSIONS: The scientific literature surrounding brain health has increased exponentially, yet measurement methods are highly heterogeneous across studies which may explain the lack of clinical translation. Future studies should aim to develop a selected group of measures that should be included in all brain health studies to aid interstudy comparison (core outcome set), and broaden from the current focus on neuroimaging outcomes to include a range of outcomes.

Having Plans for the Future in Very Old People.

This study aimed to investigate the prevalence of having plans for the future among very old people and the factors associated with having such plans. A longitudinal population-based study with home visits for 85-, 90-, and ≥95-year-old participants in Sweden and Finland was used. Multivariate logistic regression and Cox proportional-hazards regression models with a maximum 5-year follow-up period were used. The prevalence of having plans for the future was 18.6% (174/936). More men than women and more people living in Sweden than in Finland had plans for the future. In multivariate models, having plans for the future was associated with speaking Swedish, being dentate, and living in the community in the total sample; speaking Swedish and being dentate among women; and speaking Swedish, having a lower Geriatric Depression Scale score, and urban residence among men. Having plans for the future was associated univariately, but not multivariately, with increased survival.

Herpes Simplex Viral Infection Doubles the Risk of Dementia in a Contemporary Cohort of Older Adults: A Prospective Study.

Background: Evidence indicates that herpes simplex virus (HSV) participates in the pathogenesis of Alzheimer's disease (AD). Objective: We investigated AD and dementia risks according to the presence of herpesvirus antibodies in relation to anti-herpesvirus treatment and potential APOE ɛ4 carriership interaction. Methods: This study was conducted with 1002 dementia-free 70-year-olds living in Sweden in 2001-2005 who were followed for 15 years. Serum samples were analyzed to detect anti-HSV and anti-HSV-1 immunoglobulin (Ig) G, anti-cytomegalovirus (CMV) IgG, anti-HSV IgM, and anti-HSV and anti-CMV IgG levels. Diagnoses and drug prescriptions were collected from medical records. Cox proportional-hazards regression models were applied. Results: Cumulative AD and all-cause dementia incidences were 4% and 7%, respectively. Eighty-two percent of participants were anti-HSV IgG carriers, of whom 6% received anti-herpesvirus treatment. Anti-HSV IgG was associated with a more than doubled dementia risk (fully adjusted hazard ratio = 2.26, p = 0.031). No significant association was found with AD, but the hazard ratio was of the same magnitude as for dementia. Anti-HSV IgM and anti-CMV IgG prevalence, anti-herpesvirus treatment, and anti-HSV and -CMV IgG levels were not associated with AD or dementia, nor were interactions between anti-HSV IgG and APOE ɛ4 or anti-CMV IgG. Similar results were obtained for HSV-1. Conclusions: HSV (but not CMV) infection may be indicative of doubled dementia risk. The low AD incidence in this cohort may have impaired the statistical power to detect associations with AD.

Utilisation of community healthcare services among older adults with disabilities in Luohu district, Shenzhen: a community-based survey.

OBJECTIVE: China faces the challenge of an ageing population with disabilities. Community healthcare centres (CHCs) serve as frontline community healthcare providers for older adults with and without disabilities. Despite their significance, there is a lack of literature examining the utilisation of CHC services among older adults. This study aims to examine and compare the utilisation and satisfaction of CHC healthcare services among older adults with and without disabilities. SETTING: Data from the 2019 Community Health Diagnosis Questionnaire, which interviewed 259 older adults residing in the Luohu district of Shenzhen, were used in the current study. PRIMARY OUTCOME MEASURES: Participants self-reported outcomes including use of CHCs, use of home health services from CHCs and satisfaction with CHCs. Five different disability types and an integrated disability variable were assessed as independent variables. Linear probability models were used to determine the relationship between disability types and outcome variables. RESULTS: Among 259 older adults aged 60 years and older, 70.66% self-identified as having a disability. No statistically significant associations were found between the use of CHCs, the use of home health services from CHCs and satisfaction with CHCs, and disability status. However, older adults with mobility and cognitive disabilities were more likely to receive home health services from CHCs. CONCLUSION: Community health promotion policies should be implemented to improve access to health services for older adults with and without disabilities. In addition, CHCs should implement effective health management plans to ensure the health needs of older adults with disabilities.

Relationship of protein, calcium and vitamin D consumption with body composition and fractures in oldest-old independent people.

BACKGROUND & AIM: Some studies state that the protein intake has a protective effect against bone mass loss, while others show that the combination of low calcium intake and high protein consumption increases the risk of fractures. Perhaps this phenomenon is also altered by the consumption of vitamin D after the age 80 years. This study aimed to identify if there is an association of protein, calcium and vitamin D intake with body composition and fractures in community dwelling 80 years or older independent people. METHODS: This is a cross-sectional observational analytic study. We invited community dwelling 80 years or older independent people, with chronic diseases under control, according to the scientific guidelines. The food intake was obtained through a one-day food record (FR) and Avanutri software (4.1 version) was used to calculate the intake of total calories, calcium, protein, and other food nutrients. The body composition and bone densitometry were evaluated by whole-body Dual Energy X-ray Absorptiometry (DXA). The morphometric vertebral fractures were assessed through conventional X-ray of the vertebral, level T4 to L4, on side face position - semi quantitative technique. RESULTS: One hundred and fifty-nine 80 years or older independent people, mean age 87.0 ± 3.9 years old were studied. The mean calcium intake was 834.6 ± 374.7 mg/day and vitamin D was 6.1 ± 24.3 µg/day, in both cases they were complemented by supplements to reach the recommendations. The mean protein intake was 72.9 ± 26.8 g/day, we found that 48.4% had low muscle mass; there was a frequency of 45.3% of osteoporosis; and vertebral fractures in 24.7% of them. The estimates of the logistic regression model with the outcome variable obesity and low muscle mass with reference to "low muscle mass" showed that the 80 years or older independent people who have a fracture are more likely to be obese with low muscle mass compared to those with only low muscle mass. CONCLUSION: In the studied population of 80 years or older independent people, we observed that among all the nutrients studied, only dietary protein per g/kg/day was associated with body composition and bone mineral density, but not with fracture, although the elderly who have fracture are more likely to be obese with low muscle mass compared to those not obese with low muscle mass. More studies about nutrients intakes and its relationship with muscle and bone health in this population is necessary.

Myocardial oxygen supply and demand imbalance predicts mortality in older nursing home residents: The PARTAGE study.

BACKGROUND: A mismatch between myocardial oxygen supply and demand is the most common cause of ischemic myocardial injury in older persons. The subendocardial viability ratio (SEVR) can usefully estimate the degree of myocardial perfusion relative to left-ventricular workload. The aim of the present study was to evaluate the ability of SEVR to predict long-term mortality in the older population. Additionally, we aimed to identify the SEVR cutoff value best predicting total mortality. METHODS: This is a multicenter, longitudinal study involving a large population of individuals older than 80 years living in nursing homes. Patients with cancer, severe dementia, and very low level of autonomy were excluded from the study. Participants were monitored for 10 years. Adverse outcomes were recorded every 3 months from inclusion to the end of the study. SEVR reflects the balance between subendocardial oxygen supply and demand, and was estimated non-invasively by analyzing the carotid pressure waveform recorded by applanation arterial tonometry. RESULTS: A total of 828 people were enrolled (mean age: 87.7 ± 4.7 years, 78% female). 735 patients died within 10 years and 24 were lost to follow-up. SEVR was inversely associated with mortality at univariate Cox-regression model (risk ratio, 0.683 per unit increase in SEVR; 95% confidence interval (CI) [0.502-0.930], p = 0.015) and in a model including age, sex, body mass index, Activity of Daily Living index and Mini-Mental State Examination score (risk ratio, 0.647; 95% CI [0.472-0.930]). The lowest tertile of SEVR was associated with higher 10-years total mortality than the middle (p < 0.001) and the highest (p < 0.004) tertile. A SEVR cutoff value of 83% was identified as the best predictor of total mortality. CONCLUSIONS: SEVR may be considered as a marker of "cardiovascular frailty." An accurate non-invasive estimation of SEVR could be a useful and independent parameter to assess survival probability in very old adults. TRIAL REGISTRATION: NCT00901355, registered on ClinicalTrials.gov website.

A volunteer-supported walking programme to improve physical function in older people with restricted mobility (the POWER Study): a randomised controlled trial.

BACKGROUND: Regular physical activity has multiple health benefits, especially in older people. Therefore, the World Health Organization recommends at least 2.5 h of moderate physical activity per week. The aim of the POWER Study was to investigate whether volunteer-assisted walking improves the physical performance and health of older people. METHODS: We approached people aged 65 years and older with restricted mobility due to physical limitations and asked them to participate in this multicentre randomised controlled trial. The recruitment took place in nursing homes and the community setting. Participants randomly assigned to the intervention group were accompanied by volunteer companions for a 30-50 min walk up to three times a week for 6 months. Participants in the control group received two lectures that included health-related topics. The primary endpoint was physical function as measured with the Short Physical Performance Battery (SPPB) at baseline and 6 and 12 months. The secondary and safety endpoints were quality of life (EQ-5D-5L), fear of falling (Falls Efficacy Scale), cognitive executive function (the Clock Drawing Test), falls, hospitalisations and death. RESULTS: The sample comprised 224 participants (79% female). We failed to show superiority of the intervention with regard to physical function (SPPB) or other health outcomes in the intention-to-treat analyses. However, additional exploratory analyses suggest benefits in those who undertook regular walks. The intervention appears to be safe regarding falls. CONCLUSIONS: Regular physical activity is essential to preserve function and to improve health and quality of life. Against the background of a smaller-than-planned sample size, resulting in low power, and the interference of the COVID-19 pandemic, we suggest that community based low-threshold interventions deserve further exploration. TRIAL REGISTRATION: The trial was registered with the German Clinical Trials Register ( www.germanctr.de ), with number DRKS00015188 on 31/08/2018.

Pain: its prevalence and correlates among the oldest old.

BACKGROUND: There is very limited knowledge regarding pain among the oldest old. AIMS: To investigate the prevalence and correlates of pain among the oldest old. METHODS: Data were taken from the "Survey on quality of life and subjective well-being of the very old in North Rhine-Westphalia (NRW80+)", including individuals living in North Rhine-Westphalia aged 80 years and over. Pain was categorized as no pain, moderate pain and severe pain. Its prevalence was stratified by sex, age groups, marital status, place of residence and education. A multinomial logistic regression analysis was conducted. RESULTS: 28.50% of the participants reported no pain, 45.06% moderate pain and 26.44% severe pain. Regressions showed that being 85 years or older and a better self-rated health status decreased the likelihood of moderate pain. Being 85-89 years old, being male, highly educated and a better self-rated health status decreased the likelihood of severe pain. The likelihood of moderate and severe pain increased with a higher number of chronic diseases. DISCUSSION: Study findings showed a high prevalence of pain in the oldest old living in North Rhine-Westphalia, Germany. The likelihood of having moderate or severe pain was reduced among those who were older and presented with a better self-rated health but increased with a growing number of comorbidities. Severe pain was less likely among men and those with a higher education. CONCLUSION: This cross-sectional representative study adds first evidence of prevalence and correlations of pain among the oldest old. Longitudinal studies are required to further explore the determinants of pain in this age group.

Does Spinal Surgery in Elderly Patients (Over 80 Years-Old) Lead to More Early Post-Operative Complications Than Lower Limb Prosthetic Surgery?

Purpose: Patients and surgeons may be reluctant on spinal surgery over 80 years old, fearing medical complications despite the possible improvement on quality of life. However, fewer reservations for lower limb prosthetic surgery (LLPS) seem to be arisen in this population. Is spinal surgery after 80 years-old responsible of more complications than lower limb surgery? Methods: The consecutive files of 164 patients over 80 years that had spinal surgery or LLPS were analyzed. The data collected pre-operatively were demographic, clinical and post-operatively the number and types of medical complications and length of stay. Results: The mean number of medical complications was 1.11 ± 0.6 [0-6] for spinal surgery and 1.09 ± 1.0 [0-3] for LLPS, (p = 0,87). The length of stay in orthopedic unit was comparable between the two groups: 10.7 ± 4.9 days [2-36] for SS and 10.7 ± 3.0 days [5-11] for LLPS (p = 0,96). Conclusion: The global rate of peri-operative complications and the length of hospital stay were similar between spinal surgery and lower limb prosthetic surgery. These results may be explained by the rising cooperation between geriatric specialist and surgeons and the development of mini-invasive surgical technics, diminishing the early post-operative complication rates.
