Abstract
Frail older adults with ongoing care needs often require post-acute care (PAC) following acute hospitalization when not eligible for specific rehabilitation. Long-term outcomes of PAC in this patient group have not been reported for Switzerland so far. In the present report, we investigated 12-month mortality in regard to frailty status upon admission to PAC in a nursing home setting. In our sample of 140 patients (mean age 84 [±8.6] years) 4.3% were robust, 37.1% were pre-frail, 54.3% were frail and 4.3% were missing frailty status. Mortality at 12-months follow-up stratified by baseline frailty was 0% (robust), 11.5% (pre-frail) and 31.6% (frail). Kaplan-Meier analysis stratified by frailty status showed a decreased probability of 12-months survival for frail individuals compared to their pre-frail and robust counterparts (P = 0.0096). Being frail was associated with more than 4-fold increased odds of death at follow-up (OR 4.19; 95% CI 1.53-11.47).

Abstract
BACKGROUND A 2017 meta-analysis of data from 25 randomised controlled trials (RCTs) of vitamin D supplementation for the prevention of acute respiratory infections (ARIs) revealed a protective effect of this intervention. We aimed to examine the link between vitamin D supplementation and prevention of ARIs in an updated meta-analysis. METHODS For this systematic review and meta-analysis, we searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, Web of Science, and the ClinicalTrials.gov registry for studies listed from database inception to May 1, 2020. Double-blind RCTs of vitamin D3, vitamin D2, or 25-hydroxyvitamin D (25[OH]D) supplementation for any duration, with a placebo or low-dose vitamin D control, were eligible if they had been approved by a research ethics committee, and if ARI incidence was collected prospectively and prespecified as an efficacy outcome. Studies reporting results of long-term follow-up of primary RCTs were excluded. Aggregated study-level data, stratified by baseline 25(OH)D concentration and age, were obtained from study authors. Using the proportion of participants in each trial who had one or more ARIs, we did a random-effects meta-analysis to obtain pooled odds ratios (ORs) and 95% CIs to estimate the effect of vitamin D supplementation on the risk of having one or more ARIs (primary outcome) compared with placebo. Subgroup analyses were done to estimate whether the effects of vitamin D supplementation on the risk of ARI varied according to baseline 25(OH)D concentration (<25 nmol/L vs 25·0-49·9 nmol/L vs 50·0-74·9 nmol/L vs >75·0 nmol/L), vitamin D dose (daily equivalent of <400 international units [IU] vs 400-1000 IU vs 1001-2000 IU vs >2000 IU), dosing frequency (daily vs weekly vs once per month to once every 3 months), trial duration (≤12 months vs >12 months), age at enrolment (<1·00 years vs 1·00-15·99 years vs 16·00-64·99 years vs ≥65·00 years), and presence versus absence of airway disease (ie, asthma only, COPD only, or unrestricted). Risk of bias was assessed with the Cochrane Collaboration Risk of Bias Tool. The study was registered with PROSPERO, CRD42020190633. FINDINGS We identified 1528 articles, of which 46 RCTs (75 541 participants) were eligible. Data for the primary outcome were obtained for 48 488 (98·1%) of 49 419 participants (aged 0-95 years) in 43 studies. A significantly lower proportion of participants in the vitamin D supplementation group had one or more ARIs (14 332 [61·3%] of 23 364 participants) than in the placebo group (14 217 [62·3%] of 22 802 participants), with an OR of 0·92 (95% CI 0·86-0·99; 37 studies; I2=35·6%, pheterogeneity=0·018). No significant effect of vitamin D supplementation on the risk of having one or more ARIs was observed for any of the subgroups defined by baseline 25(OH)D concentration. However, protective effects of supplementation were observed in trials in which vitamin D was given in a daily dosing regimen (OR 0·78 [95% CI 0·65-0·94]; 19 studies; I2=53·5%, pheterogeneity=0·003), at daily dose equivalents of 400-1000 IU (0·70 [0·55-0·89]; ten studies; I2=31·2%, pheterogeneity=0·16), for a duration of 12 months or less (0·82 [0·72-0·93]; 29 studies; I2=38·1%, pheterogeneity=0·021), and to participants aged 1·00-15·99 years at enrolment (0·71 [0·57-0·90]; 15 studies; I2=46·0%, pheterogeneity=0·027). No significant interaction between allocation to the vitamin D supplementation group versus the placebo group and dose, dose frequency, study duration, or age was observed. In addition, no significant difference in the proportion of participants who had at least one serious adverse event in the vitamin supplementation group compared with the placebo group was observed (0·97 [0·86-1·07]; 36 studies; I2=0·0%, pheterogeneity=0·99). Risk of bias within individual studies was assessed as being low for all but three trials. INTERPRETATION Despite evidence of significant heterogeneity across trials, vitamin D supplementation was safe and overall reduced the risk of ARI compared with placebo, although the risk reduction was small. Protection was associated with administration of daily doses of 400-1000 IU for up to 12 months, and age at enrolment of 1·00-15·99 years. The relevance of these findings to COVID-19 is not known and requires further investigation. FUNDING None.

Abstract
AIM To investigate the effect of daily 800 versus 2000 IU of vitamin D3 supplementation over 24 months on glycaemic control in older adults after unilateral knee replacement. MATERIALS AND METHODS The Zurich Multiple Endpoint Vitamin D Trial in Knee OA Patients was a randomized, double-blind trial conducted from 2008 to 2014 in Zurich, Switzerland. Participants were randomly allocated to 800 or 2000 IU vitamin D3 daily for 24 months. This study investigates the predefined secondary endpoints of fasting blood glucose (FBG) and homeostatic model assessment for insulin resistance (HOMA-IR) using linear mixed models adjusted for age, sex, baseline vitamin D deficiency and body mass index. RESULTS A total of 251 participants (age 70.2 ± 6.5 years; 55.4% women; 39% impaired glucose tolerance, mean 25-hydroxyvitamin D 27.48 ± 12.48 ng/mL, mean FBG 5.49 ± 0.71 mmol/L) were included in this analysis. There was no significant difference in FBG between the group receiving 800 versus 2000 IU after 2 years with a least square mean (95% CI) of 5.32 (5.19; 5.44) versus 5.39 (5.27; 5.51) mmol/L (ptreat = .130) and no difference in HOMA-IR (0.44 [0.37; 0.52] vs. 0.49 [0.41; 0.58]; ptreat = .162), respectively. However, FBG decreased significantly over time independent of vitamin D3 dose (800 IU: 5.54 [5.42; 5.66] to 5.32 [5.19; 5.44], ptime < .001; 2000 IU: 5.5 [5.38; 5.62] to 5.39 [5.27; 5.51] mmol/L, ptime = .019). CONCLUSIONS There was no clinically meaningful difference between 800 and 2000 IU of vitamin D3 over 2 years in FBG or HOMA-IR in community-dwelling older adults. Glycaemic outcomes improved in both groups.

Abstract
INTRODUCTION Improvements in life expectancy imply that an increase of geriatric trauma patients occurs. These patients require special attention due to their multiple comorbidity issues. The aim of this study was to assess the impact of the implementation of geriatric comanagement (GC) on the allocation and clinical outcome of geriatric trauma patients. METHODS This observational cohort study aims to compare the demographic development and the clinical outcome in geriatric trauma patients (aged 70 years and older) before and after implementation of a certified geriatric trauma center (GC). Geriatric trauma patients admitted between January 1, 2010 and December 31, 2010 were stratified to group pre-GC and admissions between January 1, 2018 and December 31, 2018 to Group post-GC. We excluded patients requiring end-of-life treatment and those who died within 24 h or due to severe traumatic brain injury. Outcome parameters included demographic changes, medical complexity (measured by American Society of Anaesthesiology Score (ASA) and Charlson Comorbidity Index (CCI)), in-hospital mortality and length of hospitalization. RESULTS This study includes 626 patients in Group pre-GC (mean age 80.3 ± 6.7 years) and 841 patients in Group post-GC (mean age 81.1 ± 7.3 years). Group pre-GC included 244 (39.0%) males, group post-GC included 361 (42.9%) males. The mean CCI was 4.7 (± 1.8) points in pre-GC and 5.1 (± 2.0) points in post-GC (p <0.001). In Group pre-GC, 100 patients (16.0%) were stratified as ASA 1 compared with 47 patients (5.6%) in Group post-GC (p <0.001). Group pre-GC had significantly less patients stratified as ASA 3 or higher (n = 235, 37.5%) compared with Group post-GC (n = 389, 46.3%, p <0.001). Length of stay (LOS) decreased significantly from 10.4 (± 20.3) days in Group pre-GC to 7.9 (±22.9) days in Group post-GC (p = 0.011). The 30-day mortality rate was comparable amongst these groups (pre-GC 8.8% vs. post-GC 8.9%). CONCLUSION This study appears to support the implementation of a geriatric trauma center, as certain improvements in the patient care were found: Despite a higher CCI and a higher number of patients with higher ASA classifications, Hospital LOS, complication rates and mortality did were not increased after implementation of the CG. The increase in the case numbers supports the fact that a higher degree of specialization leads to a response by admitting physicians, as it exceeded the expectable trend of demographic ageing. We feel that a larger data base, hopefully in a multi center set up should be undertaken to verify these results.

Abstract
BACKGROUND The worldwide prevalence of dementia is increasing and represents a major public health concern. In the last decades, air travel services have undergone an impressive expansion and one of ten passengers is aged 65 years and older. While air travel can be stressful at all ages and health conditions, older individuals with cognitive impairment carry a greater risk for air-travel-related complications. Consequently, demands to general practitioners for assessing their older patient's fitness to fly are increasing. METHODS We conducted a search of the literature in PubMed on the impact of in-flight environmental changes on passengers with cognitive impairment and possible resulting complications. This set the base for a discussion on pharmacological and non-pharmacological interventions aimed at preventing in-flight complications in this vulnerable population. RESULTS While our research strategy identified a total of 11 articles related to older age and air travel, only three focused on passengers with cognitive impairment. Our literature review showed that the airplane environment may lead to a large spectrum of symptoms in passengers of all age groups. However, passengers with cognitive impairment due to neurodegenerative diseases are at increased risk for experiencing the most extreme symptoms such as acute confusional state. Non-pharmacological and pharmacological interventions at different stages of the travel process (before, during and after) can help prevent complications in this vulnerable population. CONCLUSION The decision to let a patient with cognitive impairment fly requires a solid understanding of the in-flight environmental changes and their impact on older patients with cognitive impairment. Moreover, a sound weighing of the risks and benefits while considering different aspects of the patient's history is demanded. In this regard, the role of the treating physicians and caregivers is essential along with the support of the medical department of the airline.

Abstract
Hintergrund Die geriatrische frührehabilitative Komplexbehandlung (GFK) wird bei hochbetagten hospitalisierten Patienten eingesetzt, um die Selbstversorgungsfähigkeit wiederherzustellen und eine Pflegebedürftigkeit zu vermeiden. Ziel der Arbeit Ziel der Arbeit war es, die Veränderungen von Mobilität und Selbsthilfefähigkeit bei alterstraumatologischen Patienten* im Rahmen der GFK zu beschreiben. Material und Methoden Mobilität, Ganggeschwindigkeit und Selbsthilfefähigkeit von 164 hospitalisierten Alterstraumatologiepatienten wurde zu Beginn und bei Abschluss der GFK erfasst. Wir analysierten die Veränderungen der Mobilität während GFK (t-Test), und welche Mobilitätsmerkmale mit einer Entlassung nach Hause vs. einer Entlassung in die Langzeitpflege assoziiert sind (alters- und geschlechtsadjustiertes Regressionsmodell). Ergebnisse Die Patienten verbesserten ihre Mobilität gemessen mittels Short Physical Performance Battery (SPPB) um 1,8 ± 2,1 Punkte, die Ganggeschwindigkeit um 0,10 ± 0,14 m/s und den Barthel-Index um 13 ± 16 Punkte (alle p < 0,001). Die Zahl nichtgehfähiger Patienten verringerte sich von 43 auf 14 % (p = 0,003). Die Mehrzahl (73 %) der vor der Hospitalisation zu Hause lebenden Patienten wurde direkt oder nach einer überbrückenden spitalexternen Rehabilitation nach Hause entlassen. Schlussfolgerung Die Datenanalyse zeigt signifikante und klinisch relevante Verbesserungen in den Bereichen Mobilität und Selbstständigkeit bei Alterstraumatologiepatienten. Die Mehrzahl der Patienten konnte wieder nach Hause austreten. Zusatzmaterial online Zusätzliche Informationen sind in der Online-Version dieses Artikels (10.1007/s00391-020-01812-4) enthalten.

Abstract
Importance The benefits of vitamin D, omega-3 fatty acids, and exercise in disease prevention remain unclear. Objective To test whether vitamin D, omega-3s, and a strength-training exercise program, alone or in combination, improved 6 health outcomes among older adults. Design, Setting, and Participants Double-blind, placebo-controlled, 2 × 2 × 2 factorial randomized clinical trial among 2157 adults aged 70 years or older who had no major health events in the 5 years prior to enrollment and had sufficient mobility and good cognitive status. Patients were recruited between December 2012 and November 2014, and final follow-up was in November 2017. Interventions Participants were randomized to 3 years of intervention in 1 of the following 8 groups: 2000 IU/d of vitamin D3, 1 g/d of omega-3s, and a strength-training exercise program (n = 264); vitamin D3 and omega-3s (n = 265); vitamin D3 and exercise (n = 275); vitamin D3 alone (n = 272); omega-3s and exercise (n = 275); omega-3s alone (n = 269); exercise alone (n = 267); or placebo (n = 270). Main Outcomes and Measures The 6 primary outcomes were change in systolic and diastolic blood pressure (BP), Short Physical Performance Battery (SPPB), Montreal Cognitive Assessment (MoCA), and incidence rates (IRs) of nonvertebral fractures and infections over 3 years. Based on multiple comparisons of 6 primary end points, 99% confidence intervals are presented and P < .01 was required for statistical significance. Results Among 2157 randomized participants (mean age, 74.9 years; 61.7% women), 1900 (88%) completed the study. Median follow-up was 2.99 years. Overall, there were no statistically significant benefits of any intervention individually or in combination for the 6 end points at 3 years. For instance, the differences in mean change in systolic BP with vitamin D vs no vitamin D and with omega-3s vs no omega-3s were both -0.8 (99% CI, -2.1 to 0.5) mm Hg, with P < .13 and P < .11, respectively; the difference in mean change in diastolic BP with omega-3s vs no omega-3s was -0.5 (99% CI, -1.2 to 0.2) mm Hg; P = .06); and the difference in mean change in IR of infections with omega-3s vs no omega-3s was -0.13 (99% CI, -0.23 to -0.03), with an IR ratio of 0.89 (99% CI, 0.78-1.01; P = .02). No effects were found on the outcomes of SPPB, MoCA, and incidence of nonvertebral fractures). A total of 25 deaths were reported, with similar numbers in all treatment groups. Conclusions and Relevance Among adults without major comorbidities aged 70 years or older, treatment with vitamin D3, omega-3s, or a strength-training exercise program did not result in statistically significant differences in improvement in systolic or diastolic blood pressure, nonvertebral fractures, physical performance, infection rates, or cognitive function. These findings do not support the effectiveness of these 3 interventions for these clinical outcomes. Trial Registration ClinicalTrials.gov Identifier: NCT01745263.

Abstract
Geriatric trauma is expected to increase due to the lifestyle and activity of the aging population and will be among the major future challenges in health care. Therefore, the aim of this study was to investigate differences between polytraumatized geriatric and non-geriatric patients regarding mortality, length-of-stay and complications with a matched pair analysis. We included patients older than 17 years with an Injury Severity Score (ISS) of 16 or more admitted to our level 1 trauma center between January 2008 and December 2015. The cohort was stratified into two groups (age < 70 and ≥ 70 years). One-to-one matching was performed based on gender, ISS, mechanism of injury (penetrating/blunt), Glasgow coma scale (GCS), base excess, and the presence of coagulopathy (international normalized ratio (INR) ≥ 1.4). Outcome was compared using the paired t-test and McNemar-test. A total of 1457 patients were identified. There were 1022 male (70%) and 435 female patients. Three hundred and sixty-four patients (24%) were older than 70 years. Matching resulted in 57 pairs. Mortality as well as length-of-stay were comparable between geriatric and non-geriatric polytraumatized patients. Complication rate (34% vs. 56%, p = 0.031) was significantly higher in geriatric patients. This indicates the possibility of similar outcomes in geriatric polytraumatized patients receiving optimal care.

Abstract
AIMS OF THE STUDY Mobility disability due to spinal stenosis is common in the senior population and often surgery is warranted for patients with severe symptoms and neurological dysfunction. However, although current clinical guidelines recommend stabilisation surgery in addition to decompression in patients with spinal stenosis and instability due to degenerative spondylolisthesis, the relationship between outcomes and the specific type of surgery have not been well studied. We therefore assessed the postoperative recovery timeline for 12 months and compared patient-reported outcomes dependent on the extent of decompression and additional stabilisation among seniors undergoing spinal stenosis surgery. METHODS We investigated 457 patients (mean age 76.0 ± 10.7 years, 58% women) from a consecutive cohort prior to spinal stenosis surgery. Follow-up was at 3 or 6months and at 12 months postoperatively. At each visit, pain, neurological dysfunction and disability were assessed using the North American Spine Society questionnaire. Repeated-measures analysis compared outcomes by type of surgery adjusting for baseline symptoms, gender, age, number of comorbidities, centre and year of surgery. RESULTS Most improvement occurred within the first 3 to 6 months with little or no further improvement at 12 months. Over 12 months and in adjusted models, patients receiving one-segment versus multi-segment decompression experienced significantly greater reduction of pain (−49.2% vs −41.9%, p = 0.013) and neurological dysfunction (−37.1% vs −25.9%, p <0.0001), but only borderline greater reduction of disability (−32.7% vs −28.2%, p = 0.051). Moreover, reduction in pain and neurological function did not differ with or without additional stabilisation and extend of decompression. However, patients who received one-segment (−28.9%) or multi-segment (−28.3%) stabilisation experienced significantly less reduction in disability after surgery compared with those who were not stabilised (−34.1%, p <0.043). CONCLUSIONS Among senior patients undergoing spinal stenosis surgery, recovery was largely complete by 3 to 6 months after surgery and differed little by type of surgery independently of symptoms prior to surgery and other covariates. However we could document a trend toward more improvement in particularly neurological dysfunction and disability with less invasive surgery.

Abstract
BACKGROUND Observational studies report higher blood pressure (BP) among individuals with lower 25-hydroxyvitamin D concentration. Whether dosage of vitamin D supplementation has a differential effect on BP control remains unclear. OBJECTIVE The study aimed to determine if daily vitamin D supplementation with 2000 IU is more effective than 800 IU for BP control among older adults. METHODS This randomized, double-blind, ancillary trial of the Zurich Multiple Endpoint Vitamin D Trial in Knee Osteoarthritis enrolled adults aged ≥60 y who underwent elective surgery due to severe knee osteoarthritis. Participants were randomly assigned to receive high dose (2000 IU) or standard dose (800 IU) daily vitamin D3 for 24 mo. Outcomes included daytime and 24-h mean systolic BP. BP variability and serum 25-hydroxyvitamin D concentration were examined in a post hoc and observational analysis. RESULTS Of the 273 participants randomly assigned, 250 participants completed a follow-up 24-h ambulatory BP monitoring (mean age: 70.4 ± 6.4 y; 47.2% men). The difference in daytime mean systolic BP reduction between the 2000 IU (n = 123) and 800 IU (n = 127) groups was not statistically significant (-2.75 mm Hg vs. -3.94 mm Hg; difference: 1.18 mm Hg; 95% CI: -0.68, 3.05; P = 0.21), consistent with 24-h mean systolic BP. However, systolic BP variability was significantly reduced with 2000 IU (average real variability: -0.37 mm Hg) compared to 800 IU vitamin D3 (0.11 mm Hg; difference: -0.48 mm Hg; 95% CI: -0.94, -0.01; P = 0.045). Independent of group allocation, maximal reductions in mean BP were observed at 28.7 ng/mL of achieved serum 25-hydroxyvitamin D concentrations. CONCLUSIONS While daily 2000 IU and 800 IU vitamin D3 reduced mean systolic BP over 2 y to a small and similar extent, 2000 IU reduced mean systolic BP variability significantly more compared with 800 IU. However, without a placebo control group we cannot ascertain whether vitamin D supplementation effectively reduces BP.This trial was registered at www.clinicaltrials.gov as NCT00599807.

Abstract
IMPORTANCE Falls increase morbidity and mortality in adults 65 years and older. The role of dance-based mind-motor activities in preventing falls among healthy older adults is not well established. OBJECTIVE To assess the effectiveness of dance-based mind-motor activities in preventing falls. DATA SOURCES Systematic search included the PubMed, Embase, Cochrane Library, Web of Science, CINAHL, PsychINFO, Abstracts in Social Gerontology, AgeLine, AMED, and Scopus databases from database inception to February 18, 2018, using the Medical Subject Headings aged 65 and older, accidental falls, and dancing. STUDY SELECTION This systematic review and meta-analysis included 29 randomized clinical trials that evaluated a dance-based mind-motor activity in healthy older adults with regard to fall risk, fall rate, or well-established measures of physical function in the domains of balance, mobility, and strength. The included studies targeted participants without comorbidities associated with higher fall risk. Dance-based mind-motor activities were defined as coordinated upright mind-motor movements that emphasize dynamic balance, structured through music or an inner rhythm (eg, breathing) and distinctive instructions or choreography, and that involve social interaction. DATA EXTRACTION AND SYNTHESIS Standardized independent screening, data extraction, and bias assessment were performed. Data were pooled using random-effects models. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline. MAIN OUTCOMES AND MEASURES Primary outcomes were risk of falling and rate of falls. For the secondary end points of physical function (balance, mobility, and strength), standardized mean differences (SMDs) were estimated and pooled (Hedges g). RESULTS In this systematic review and meta-analysis of 29 randomized clinical trials, dance-based mind-motor activities were significantly associated with reduced (37%) risk of falling (risk ratio, 0.63; 95% CI, 0.49-0.80; 8 trials, 1579 participants) and a significantly reduced (31%) rate of falls (incidence rate ratio, 0.69; 95% CI, 0.53-0.89; 7 trials, 2012 participants). In addition, dance-based mind-motor activities were significantly associated with improved physical function in the domains of balance (standardized mean difference [SMD], 0.62; 95% CI, 0.33-0.90; 15 trials, 1476 participants), mobility (SMD, -0.56; 95% CI, -0.81 to -0.31; 13 trials, 1379 participants), and lower body strength (SMD, 0.57; 95% CI, 0.23-0.91; 13 trials, 1613 participants) but not upper body strength (SMD, 0.18; 95% CI, -0.03 to 0.38; 4 trials, 414 participants). CONCLUSION AND RELEVANCE Among healthy older adults, dance-based mind-motor activities were associated with decreased risk of falling and rate of falls and improved balance, mobility, and lower body strength. This type of activity may be useful in preventing falls in this population.

Contemp Clin Trials 2020; 100:106124.

Abstract
DO-HEALTH is a multi-center clinical trial among 2157 community-dwelling European men and women age 70 and older. The 2x2x2 randomized-control factorial design trial tested the individual and additive benefit, as well as the cost-effectiveness, of 3 interventions: vitamin D 2000 IU/day, omega-3 fatty acids 1000 mg/day (EPA + DHA, ratio 1:2), and a 30-minute 3 times/week home exercise (strength versus flexibility). Each treatment tested has shown considerable prior promise from mechanistic studies, small clinical trials, or large cohort studies, in the prevention of common age-related chronic diseases, but definitive data are missing. DO-HEALTH will test these interventions in relation to 6 primary endpoints (systolic and diastolic blood pressure, non-vertebral fractures, Short Physical Performance Battery score, the Montreal Cognitive Assessment, and risk of infections), plus several secondary endpoints explored in ancillary studies (i.e. rate of any falls and injurious falls, joint pain, oral health, quality of life, and incident frailty). As the 3 interventions have distinct mechanisms of action for each of the 6 primary endpoints, a maximum benefit is expected for their additive benefit as a "multi-modal" intervention. The trial duration is 3 years with in-person contacts with all participants at 4 clinical visits and by quarterly phone calls. Baseline and follow-up blood samples were collected in all participants to measure changes in 25-hydroxyvitamin D and poly-unsaturated fatty acid concentrations. Our objective was to test interventions that are expected to promote healthy aging and longer life expectancy and that can be easily and safely implemented by older community-dwelling adults.

Abstract
BACKGROUND Elucidating behavioral protective factors for cognitive decline and dementia can have a far-reaching impact. AIMS To describe the association of present and past musical instrument playing with cognitive function in cognitively intact older adults. METHOD A post hoc observational analysis of the Zurich Disability Prevention Trial. Past and present musical instrument playing was correlated with Mini-Mental State Examination (MMSE) and EuroQol-Visual Analogue Scale (EQ-VAS) using linear regression at baseline and mixed-model linear regression over 1 year. RESULTS Two hundred community dwelling adults age 70 and older (mean age 77.7) were included. There were 48.5% (97/200) participants, who ever played a musical instrument; 35% (70/200) played in the past and 13.5% (27/200) played at present. At baseline, present players had a suggestively higher adjusted-MMSE than never players (28.9 vs. 28.5, p value 0.059). Over 12 months, compared to never players, ever players showed a significantly better improvement from baseline in adjusted-MMSE (0.29 vs. - 0.12, p value 0.007). The association remained significant even after restricting to participants without higher education (p value 0.03). Over time, no differences were observed for EQ-VAS (p value 0.45). However, past players had the largest decline in health-related quality of life at 12 months. DISCUSSION The support for a protective association in our observational study suggests the need for clinical trials to examine the effect of playing a musical instrument on cognitive function and decline. Both returning to play after an interruption and learning to play from the beginning should be examined. CONCLUSIONS Present and past musical instrument playing may assist in preserving cognitive function in community-dwelling older adults.

Abstract
AIMS OF THE STUDY Post-acute care (PAC) is intended for older adult patients who are unable to return home directly after acute hospitalisation but who do not otherwise qualify for specific rehabilitation. However, data on potential predictors of PAC outcomes remain limited. Our aim was to identify patient characteristics upon admission to PAC that are associated with subsequent institutionalisation. METHODS Prospective cohort study enrolling 140 former acute care inpatients aged 60 and older who were referred to PAC units at nursing homes in Zurich, Switzerland. MEASURES Geriatric assessment at admission included Barthel Index (BI), Short Physical Performance Battery (SPPB), frailty status (Fried phenotype), nutrition and cognitive status. Logistic regression was used to determine statistically significant associations. RESULTS Mean age was 84.1 (standard deviation [SD] 8.6) years; 62.9% of participants were women. Mean body mass index (BMI) was 25.0 (SD 5.8) kg/m2, with 12.1% being underweight (BMI <20 kg/m2). Mean BI at admission was 62.1 (SD 19.1), mean SPPB score was 5.2 (SD 2.8), and 55% were frail (≥3 Fried criteria present). After a mean length of stay in PAC of 30.9 (SD 16.5) days, 48.6% were institutionalised. Patients who were frail at admission had a 2.97-fold higher (odds ratio [OR] 2.9,7 95% confidence interval [CI] 1.04–8.42), and patients who were underweight had a 4.94-fold higher (OR 4.94, 95% CI 1.11–22.01) chance of institutionalisation. Conversely, each points increment on the SBBP score lowered the likelihood of institutionalisation by 23% (OR 0.77, 95% CI 0.65–0.92). CONCLUSIONS Frailty, low Short Physical Performance Battery score and being underweight at admission to PAC were significantly associated with a higher chance of subsequent institutionalisation. Strategies to improve these factors could improve post-acute care outcomes.

Abstract
Vitamin D deficiency is widespread in geriatric patients. While vitamin D deficiency is prevalent in about 50% of healthy older adults, the prevalence in geriatric patients with hip fracture increases to over 80%. This is partly due to the fact that sunlight is unreliable as the main source of vitamin D. In addition to insufficient sun intensity from November to April, skin aging plays an important role; it causes a 4-fold reduction in the skin's own vitamin D production during sunshine exposure in older adults compared with younger people. Immobility and institutionalization are additional risk factors for vitamin D deficiency in geriatric patients. At the same time, vitamin D deficiency (< 20 ng/ml) increases parathyroid hormone levels and thus promotes bone loss and the risk of fracture. Severe vitamin D deficiency (< 10 ng/ml) may also lead to reversible muscle weakness resulting in an increased risk of falling. Since falls affect at least every second geriatric patient and hip fractures increase exponentially after the age of 75, the correction of vitamin D deficiency is an important medical and public health effort in these patients. Several randomized intervention trials, comparing 800-1000 IU vitamin D/day versus placebo or calcium, showed a significant reduction in falls and hip fractures in adults ≥65 years of age who had an increased risk of vitamin D deficiency and of falls or fractures. In geriatric patients, implementing vitamin D supplementation at this dosage is currently preferred. A bolus dose of over 24,000 IU/month should be avoided due to the increased risk of falls and fractures. These recommendations remain relevant after a critical review of the four most recent meta-analyses.

J Am Med Dir Assoc 2020; 21:1327-1330.

Abstract
OBJECTIVES To assess the validity of 4 functional tests in predicting falls within the first year after hip fracture. DESIGN Prospective study of functional tests shortly after hip surgery and incident falls during 12 months' follow-up. SETTING AND PARTICIPANTS The sample comprised 173 adults with acute hip fracture, aged 65 years and older (79% women, 77% community dwelling, mean age 84.2 years), who participated in a clinical trial of vitamin D or home exercise. METHODS We assessed 4 functional tests [Timed Up and Go test (TUG), grip strength, and knee flexor and extensor strength in the nonoperated leg] by trained study physiotherapists at baseline (1-12 days after hip fracture surgery). During 12 months' follow-up, we ascertained all fall events by monthly personal phone calls, a telephone hotline, and a patient diary. Then we compared TUG and strength test performance at baseline between future single fallers, recurrent fallers, and nonfallers over the 12-month follow-up. All analyses adjusted for age, body mass index, gender, 25-hydroxyvitamin D status at baseline, days of follow-up, and treatment allocation (the original trial tested vitamin D treatment and/or a home exercise program). RESULTS Ninety-two of 173 (53%) participants fell and experienced 212 falls. Participants who became recurrent fallers (n = 54) had significantly longer TUG times at baseline than those who did not fall (n = 81) in the following 12 months (mean TUG for recurrent fallers = 71.6 seconds, SD = 8.2 seconds, vs mean TUG for nonfallers = 51.4 seconds, SD = 6.9 seconds; P = .02). There were no significant differences in TUG times between single fallers and nonfallers. For all 3 strength tests, there were no significant differences between single fallers, recurrent fallers, and nonfallers. CONCLUSIONS AND IMPLICATIONS In this population of frail older adults recruited shortly after hip fracture surgery, only the TUG test discriminated between future recurrent fallers and nonfallers over a 12-month follow-up. Because of the high incidence and serious consequences of falls in older adults after a hip fracture, it is very important to identify practical and clinically related tests to predict repeated falls in the first year after a hip fracture, which is of great public health importance.

Abstract
Biomarkers of frailty and sarcopenia are essential to advance the understanding of these conditions of aging and develop new diagnostic tools and effective treatments. The International Conference on Frailty and Sarcopenia Research (ICFSR) Task Force - a group of academic and industry scientists from around the world -- met in February 2019 to discuss the current state of biomarker development for frailty and sarcopenia. The D3Cr dilution method, which assesses creatinine excretion as a biochemical measure of muscle mass, was suggested as a more accurate measure of functional muscle mass than assessment by dual energy x-ray absorptiometry (DXA). Proposed biomarkers of frailty include markers of inflammation, the hypothalamic-pituitary-adrenal (HPA) axis response to stress, altered glucose insulin dynamics, endocrine dysregulation, aging, and others, acknowledging the complex multisystem etiology that contributes to frailty. Lack of clarity regarding a regulatory pathway for biomarker development has hindered progress; however, there are currently several international efforts to develop such biomarkers as tools to improve the treatment of individuals presenting these conditions.

Abstract
The relevance of vitamin D for infections after kidney transplantation is poorly defined. 25-OH vitamin D (25-OHD) levels of 135 kidney transplant recipients, enrolled in the Swiss Transplant Cohort Study, were determined peri-transplant and 6 months post-transplant. Logistic regression was used to address the associations of 25-OHD and overall infections and bacterial infections, respectively. For the first 6 months post-transplant, 25-OHD peri-transplant, and for the second period (after 6 to 30 months post-transplant), 25-OHD at 6 months post-transplant was considered. Vitamin D deficiency was common peri-transplant and remained highly prevalent 6 months after transplantation despite frequent supplementation. Median 25-OHD levels increased from 12.0 ng/mL (IQR 5.3-19.5) peri-transplant to 16.5 ng/mL (IQR 10.6-22.6) 6 months post-transplant (P = .005). We did not detect a significant association between 25-OHD and overall infections (adjusted odds ratio (aOR) 1.05, 95% confidence interval (95%CI) 0.44-2.51; aOR 0.67, 95%CI 0.31-1.43) or bacterial infections (aOR 0.79, 95%CI 0.32-1.96; aOR 0.79, 95%CI 0.35-1.75) for the first and second period. To conclude, at both time points, vitamin D deficiency was observed in more than 50% of kidney recipients, albeit an increase in 25-OHD in the longitudinal course was observed. No significant association between 25-OHD and infections was detected.

Abstract
AIMS OF THE STUDY To analyse medical end-of-life decision making among the oldest old (80+ years) in Switzerland, focusing not only on treatments withheld or withdrawn but also on those continued until death. METHODS This was a retrospective follow-up study of deaths registered in Switzerland between August 2013 and January 2014 using a standardised questionnaire completed by the attending physician. All individuals aged 65 years and older who did not die suddenly and completely unexpectedly, and who had met the responding physician prior to death were included (n = 2842). We examined three age groups: 65–79, 80–89, and 90+ years. Logistic regression analysis was used to identify age-related differences, controlled for place of death and sociodemographic characteristics. RESULTS In 83.8% of the study population at least one medical end-of-life decision was made, and for 39.4% the use of a potentially life-sustaining treatment was documented. Alleviation of pain and other symptoms with a possible life-shortening effect was performed with 29% higher odds among the 90+-year-olds (odds ratio [OR] 1.29, 95% confidence interval [CI] 1.01–1.66) than in the youngest age group. Withholding or withdrawing potentially life-sustaining treatment with or without the explicit intention to hasten death did not differ with age. However, when the frequency of withholding a potentially life-sustaining treatment was compared with the frequency of using this treatment (either continued until death or withdrawn later on), the former was more common in old age (80–89 years), and particularly in very old age (90+ years) for most of the treatments studied. This applied especially for ventilator therapy (80–89 years: OR 2.83, 95% CI 1.82–4.41; 90+ years: OR 6.17, 95% CI 2.89–13.17, compared with 65–79 years), artificial nutrition (ORs 2.33, 95% CI 1.46–3.71 and 4.44, 95% CI 2.28–8.65, respectively), and antibiotics (ORs 1.53, 95% CI 1.11–2.09 and 1.57, 95% CI 1.05–2.35, respectively). Age had no independent impact on artificial hydration. CONCLUSIONS The use of some potentially life-sustaining treatments decreased with older age and, in relation, the relative frequency of withholding such treatments increased. There may be various reasons for this finding: less benefit of a particular treatment in older patients for instance due to comorbidities, higher burden of treatment, and finally a tacit consensus of physicians and patients that death is nearing.

Abstract
Diet patterns associated with low chronic inflammation may modulate cognitive decline. We investigated an empirical dietary pattern (EDP) associated with inflammation in five European countries and its association with cognitive changes over 3-years. This prospective study included 2157 community dwelling-seniors 70 years and older, followed for 3 years as part of DO-HEALTH, a randomized clinical trial. At baseline, participants completed a food frequency questionnaire and C-Reactive Protein (CRP) and interleukin-6 (IL-6) was measured. We used the Montreal Cognitive Assessment (MoCA) every year of the study. Based on reduced rank regression, we estimated a dietary pattern associated with CRP and IL-6. To evaluate the association between the EDP and cognitive changes over time, we used repeated measure linear regression models adjusting for age, total calories, BMI, study center, time, alcohol intake, education, physical activity, presence of depression symptoms, hypertension, diabetes or heart disease. The EDP was characterized by higher intakes of red and organ meat, refined grains, legumes, poultry and white fish, and lower intakes of coffee, tea, ginger, nuts and cheese. In multivariate adjusted models, participants with lowest adherence to the EDP (range -7.3 to -0.3) increased their MoCA scores 0.7 points over three years whereas those with highest adherence (range 0.4-10.1) increased their MoCA scores only by 0.2 points (p=0.01). In conclusion, a low inflammatory diet was associated with better cognitive function over time among adults ≥70 years from five European countries. This finding supports the role of diet in the promotion of cognitive health among older adults.

Abstract
UNLABELLED In this prospective study, half of all falls resulted in injury. Pre-frail adults sustained more injuries, while more frail adults had injuries requiring hospitalization or fractures. Pre-frail adults fell more often when in movement compared with frail adults who fell more often when standing and in indoor public spaces. PURPOSE To assess prospectively how fall environment and direction are related to injury among pre-frail and frail adults. METHODS We included 200 community-dwelling adults with a prior fall (pre-frail, mean age 77 years) and 173 adults with acute hip fracture (frail, mean age 84 years; 77% community-dwelling). Falls were prospectively recorded using standardized protocols in monthly intervals, including date, time, fall direction and environment, and injury. We used logistic regression to assess the odds of injury adjusting for age, body mass index (BMI), and gender. RESULTS We recorded 513 falls and 331 fall-related injuries (64.5%) among the 373 participants. While the fall rate was similar between groups, pre-frail adults had more injuries (71% among pre-frail vs. 56% among frail, p = 0.0004) but a lower incidence of major injuries (9% among pre-frail vs. 27% among frail, p = 0.003). Pre-frail adults fell more often while in movement (84% among pre-frail vs. 55% among frail, p < 0.0001), and frail adults fell more often while standing (26% vs. 15% respectively, p = 0.01). The odds of injury among frail adults was increased 3.3-fold when falling sideways (OR = 3.29, 95% CI = 1.68-6.45) and 2.4-fold when falling in an indoor public space (OR = 2.35, 95% CI = 1.00-5.53), and was reduced when falling at home (OR = 0.55, 95% CI = 0.31-0.98). The odds of injury among pre-frail adults was not influenced by environment and was 53% lower when falling backwards (OR = 0.47, 95% CI = 0.26-0.82). CONCLUSION While pre-frail adults sustain more fall-related injuries, frail adults were more likely to sustain major injuries, especially when falling sideways or outside their home.
