Introduction Anticholinergic medications block the neurotransmitter acetylcholine in the brain and peripheral nervous system. Many medications have anticholinergic properties, and the cumulative effect of these medications is termed anticholinergic burden. Increased anticholinergic burden can have short-term side effects such as dry mouth, blurred vision and urinary retention as well as long-term effects including dementia, worsening physical function and falls. Methods We carried out a systematic review (SR) with meta-analysis (MA) looking at randomised controlled trials addressing interventions to reduce anticholinergic burden in older adults. Results We identified seven papers suitable for inclusion in our SR and MA. Interventions included multi-disciplinary involvement in medication reviews and deprescribing of AC medications. Pooled data revealed no significant difference in outcomes between control and intervention group for falls (OR = 0.76, 95% CI: 0.52–1.11, n  = 647), cognition (mean difference = 1.54, 95% CI: −0.04 to 3.13, n  = 405), anticholinergic burden (mean difference = 0.04, 95% CI: −0.11 to 0.18, n  = 710) or quality of life (mean difference = 0.04, 95% CI: −0.04 to 0.12, n  = 461). Discussion Overall, there was no significant difference with interventions to reduce anticholinergic burden. As we did not see a significant change in anticholinergic burden scores following interventions, it is likely other outcomes would not change. Short follow-up time and lack of training and support surrounding successful deprescribing may have contributed. [ABSTRACT FROM AUTHOR]

Background the prevalence of adverse drug reactions (ADRs) in hospitalised older patients, their clinical presentations, causative drugs, severity, preventability and measurable outcomes are unclear, ADRs being an increasing challenge to older patient safety. Methods we systematically searched PubMed, Embase, EBSCO-CINAHL, the Cochrane Library, 'rey' literature and relevant systematic review bibliographies, published from database inception to March 2020. We included any study reporting occurrence of in-hospital ADRs as primary or secondary outcomes in hospitalised older adults (mean age ≥ 65 years). Two authors independently extracted relevant information and appraised studies for bias. Study characteristics, ADR clinical presentations, causative drugs, severity, preventability and clinical outcomes were analysed. Study estimates were pooled using random-effects meta-analytic models. Results from 2,399 abstracts, we undertook full-text screening in 286, identifying 27 studies (29 papers). Final analysis yielded a pooled ADR prevalence of 16% (95%CI 12–22%, I 2 98%, τ 2 0.8585), in a population of 20,153 hospitalised patients aged ≥65 years of whom 2,479 patients experienced ≥ one ADR. ADR ascertainment was highly heterogeneous. Almost 48.3% of all ADRs involved five presentations: fluid/electrolyte disturbances (17.3%), gastrointestinal motility/defaecation disorders (13.3%), renal disorders (8.2%), hypotension/blood pressure dysregulation disorders/shock (5.5%) and delirium (4.1%). Four drug classes accounted for 57.8% of causative medications i.e. diuretics (19.8%), anti-bacterials (14.8%), antithrombotic agents (12.2%) and analgesics (10.9%). Pooled analysis of severity was not feasible. Four studies reported the majority of ADRs as preventable (55–95%). Conclusions on average, 16% of hospitalised older patients experience significant ADRs, varying in severity and mostly preventable, with commonly prescribed drug classes accounting for most ADRs.

Introduction Neuromuscular electrical stimulation (NMES) is a treatment to prevent or reverse acquired disability in hospitalised adults. We conducted a systematic review and meta-analysis of its effectiveness. Method We searched MEDLINE, EMBASE, Cumulative Index to Nursing & Allied Health (CINAHL) and the Cochrane library. Inclusion criteria: randomised controlled trials of hospitalised adult patients comparing NMES to control or usual care. The primary outcome was muscle strength. Secondary outcomes were muscle size, function, hospital length of stay, molecular and cellular biomarkers, and adverse effects. We assessed risk of bias using the Cochrane risk-of-bias tool. We used Review Manager (RevMan) software for data extraction, critical appraisal and synthesis. We assessed certainty using the Grading of Recommendations Assessment, Development and Evaluation tool. Results A total of 42 papers were included involving 1,452 participants. Most studies had unclear or high risk of bias. NMES had a small effect on muscle strength (moderate certainty) (standardised mean difference (SMD) = 0.33; P  < 0.00001), a moderate effect on muscle size (moderate certainty) (SMD = 0.66; P  < 0.005), a small effect on walking performance (moderate certainty) (SMD = 0.48; P  < 0.0001) and a small effect on functional mobility (low certainty) (SMD = 0.31; P  < 0.05). There was a small and non-significant effect on health-related quality of life (very low certainty) (SMD = 0.35; P  > 0.05). In total, 9% of participants reported undesirable experiences. The effects of NMES on length of hospital stay, and molecular and cellular biomarkers were unclear. Conclusions NMES is a promising intervention component that might help to reduce or prevent hospital-acquired disability. [ABSTRACT FROM AUTHOR]

Objective: hip fracture is a common and serious condition associated with high mortality. This study aimed to identify pre-operative characteristics which are associated with an increased risk of mortality after hip fracture surgery.Design: systematic search of published and unpublished literature databases, including EMBASE, MEDLINE, AMED, CINAHL, PubMed and the Cochrane Library, was undertaken to identify all clinical studies on pre-operative predictors of mortality after surgery in hip fracture with at least 3-month follow-up. Data pertaining to the study objectives was extracted by two reviewers independently. Where study homogeneity was evidence, a meta-analysis of pooled relative risk and 95% confidence intervals was performed for mortality against pre-admission characteristics.Results: fifty-three studies including 544,733 participants were included. Thirteen characteristics were identified as possible pre-operative indicators for mortality. Following meta-analysis, the four key characteristics associated with the risk of mortality up to 12 months were abnormal ECG (RR: 2.00; 95% CI: 1.45, 2.76), cognitive impairment (RR: 1.91; 95% CI: 1.35, 2.70), age >85 years (RR: 0.42; 95% CI: 0.20, 0.90) and pre-fracture mobility (RR: 0.13; 95% CI: 0.05, 0.34). Other statistically significant pre-fracture predictors of increased mortality were male gender, being resident in a care institution, intra-capsular fracture type, high ASA grade and high Charlson comorbidity score on admission.Conclusions: this review has identified the characteristics of patients with a high risk of mortality after a hip fracture surgery beyond the peri-operative period who may benefit from comprehensive assessment and appropriate management.PROSPERO Registration Number: CRD42012002107.

Scope: it has been suggested that overweight/obesity as a risk factor for incident dementia differs between mid-life and later life. We performed a systematic review and meta-analysis ofthe up-to-date current literature to assess this. Search Methods: inclusion criteria included epidemiological longitudinal studies published up to September 2014, in participants without cognitive impairment based on evidence of cognitive assessment and aged 30 or over at baseline assessment with at least 2 years of follow-up. Pubmed, Medline, EMBASE, PsychInfo and the Cochrane Library were searched using combinations of the search terms: Dementia, Alzheimer disease, Vascular Dementia, Multi-Infarct Dementia, Cognitive decline, Cognitive impairment, Mild Cognitive Impairment/Obesity, Overweight, Adiposity, Waist circumference (limits: humans, English language). Handsearching of all papers meeting the inclusion criteria was performed. A random-effects model was used for the meta-analysis. Results: ofthe 1,612 abstracts identified and reviewed, 21 completely met the inclusion criteria. Being obese below the age of 65 years had a positive association on incident dementia with a risk ratio (RR) 1.41 (95% confidence interval, CI: 1.20-1.66), but the opposite was seen in those aged 65 and over, RR 0.83 (95% CI: 0.74-0.94). Conclusions: this systematic review and meta-analysis suggests a positive association between obesity in mid-life and later dementia but the opposite in late life. Whether weight reduction in mid-life reduces risk is worthy of further study. [ABSTRACT FROM AUTHOR]

Introduction The prevalence of frailty at population level is unclear. We examined this in population-based studies, investigating sources of heterogeneity. Methods PubMed, Embase, CINAHL and Cochrane Library databases were searched for observational population-level studies published between 1 January 1998 and 1 April 2020, including individuals aged ≥50 years, identified using any frailty measure. Prevalence estimates were extracted independently, assessed for bias and analysed using a random-effects model. Results In total, 240 studies reporting 265 prevalence proportions from 62 countries and territories, representing 1,755,497 participants, were included. Pooled prevalence in studies using physical frailty measures was 12% (95% CI = 11–13%; n  = 178), compared with 24% (95% CI = 22–26%; n  = 71) for the deficit accumulation model (those using a frailty index, FI). For pre-frailty, this was 46% (95% CI = 45–48%; n  = 147) and 49% (95% CI = 46–52%; n  = 29), respectively. For physical frailty, the prevalence was higher among females, 15% (95% CI = 14–17%; n  = 142), than males, 11% (95% CI = 10–12%; n  = 144). For studies using a FI, the prevalence was also higher in females, 29% (95% CI = 24–35%; n  = 34) versus 20% (95% CI = 16–24%; n  = 34), for males. These values were similar for pre-frailty. Prevalence increased according to the minimum age at study inclusion. Analysing only data from nationally representative studies gave a frailty prevalence of 7% (95% CI = 5–9%; n  = 46) for physical frailty and 24% (95% CI = 22–26%; n  = 44) for FIs. Conclusions Population-level frailty prevalence varied by classification and sex. Data were heterogenous and limited, particularly from nationally representative studies making the interpretation of differences by geographic region challenging. Common methodological approaches to gathering data are required to improve the accuracy of population-level prevalence estimates. Protocol registration PROSPERO-CRD42018105431.

Background the number of older people living in residential and nursing care homes is rising. Loneliness is a major problem for older people, but little is known about the prevalence of loneliness amongst older people living in care homes. Aim to undertake a systematic review of literature on the prevalence of moderate and severe loneliness amongst older people living in residential and nursing care homes. Design we systematically reviewed the databases Cumulative Index to Nursing and Allied Health Literature (CINAHL), MEDLINE, PsycINFO, Embase, Scopus, Cochrane and Allied and Complementary Medicine Database (AMED) from inception to January 2019. We included all studies reporting data on the prevalence of loneliness amongst older people living in care homes. A random-effects meta-analysis was conducted on all eligible data. Results a total of 13 articles were included, representing 5,115 participants (age range of 55–102 years, mean age 83.5 years, 68% female). There was a significant variation between studies in estimates of prevalence. The prevalence of moderate loneliness ranged from 31 to 100%, and the prevalence of severe loneliness ranged from 9 to 81%. The estimated mean prevalence of 'moderate loneliness' was 61% (95% confidence interval (CI): 0.41, 0.80). The estimated mean prevalence of 'severe loneliness' was 35% (95% CI: 0.14, 0.60). Conclusion the prevalence of both moderate loneliness and severe loneliness amongst care home residents is high enough to warrant concern. However, the significant variation in prevalence estimates warrants further research. Future studies should identify which interventions can address loneliness and promote meaningful social engagement to enhance quality of life in care homes. [ABSTRACT FROM AUTHOR]

Background: the worldwide population is ageing. One expected consequence of this is an increase in morbidity and an associated increased demand for long-term care. Physical rehabilitation is beneficial in older people, but relatively little is known about effects in residents of long-term care facilities.Objective: to examine the effects of physical rehabilitation on activities of daily living (ADL) in elderly residents of long-term care facilities.Methods: systematic review with meta-analysis of randomised controlled trials. We included studies that compared the effect of a physical rehabilitation intervention on independence in ADL with either no intervention or an alternative intervention in older people (over 60 years) living in long-term care facilities. We searched 19 databases including the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, AMED, Web of Knowledge and Google Scholar. Two researchers independently screened papers and extracted data. Outcomes of included studies were combined in a standardised mean difference random-effects meta-analysis.Results: thirteen of 14 studies identified were included in the meta-analysis. Independence in ADL was improved by 0.24 standard units (95% CI: 0.11–0.38; P = 0.0005). This is equivalent to 1.3 points on the Barthel Index (0–20 scale). No significant differences in effect were found based on participant or intervention characteristics. Larger sample size and low attrition were associated with smaller estimates of effect. All studies were assessed to be at risk of bias.Conclusions: physical rehabilitation may improve independence for elderly long-term care facility residents, but mean effects are small. It is unclear which interventions are most appropriate. [ABSTRACT FROM AUTHOR]

Background community-based complex interventions for older adults have a variety of names, including Comprehensive Geriatric Assessment, but often share core components such as holistic needs assessment and care planning. Objective to summarise evidence for the components and effectiveness of community-based complex interventions for improving older adults' independent living and quality of life (QoL). Methods we searched nine databases and trial registries to February 2022 for randomised controlled trials comparing complex interventions to usual care. Primary outcomes included living at home and QoL. Secondary outcomes included mortality, hospitalisation, institutionalisation, cognitive function and functional status. We pooled data using risk ratios (RRs) or standardised mean differences (SMDs) with 95% confidence intervals (CIs). Results we included 50 trials of mostly moderate quality. Most reported using holistic assessment (94%) and care planning (90%). Twenty-seven (54%) involved multidisciplinary care, with 29.6% delivered mainly by primary care teams without geriatricians. Nurses were the most frequent care coordinators. Complex interventions increased the likelihood of living at home (RR 1.05; 95% CI 1.00–1.10; moderate-quality evidence) but did not affect QoL. Supported by high-quality evidence, they reduced mortality (RR 0.86; 95% CI 0.77–0.96), enhanced cognitive function (SMD 0.12; 95% CI 0.02–0.22) and improved instrumental activities of daily living (ADLs) (SMD 0.11; 95% CI 0.01–0.21) and combined basic/instrumental ADLs (SMD 0.08; 95% CI 0.03–0.13). Conclusions complex interventions involving holistic assessment and care planning increased the chance of living at home, reduced mortality and improved cognitive function and some ADLs.

Background Delirium is a common complication clinically and is associated with the poor outcomes, yet it is frequently unrecognised and readily disregarded. Although the 3-minute diagnostic interview for confusion assessment method-defined delirium (3D-CAM) has been used in a variety of care settings, a comprehensive evaluation of its accuracy in all available care settings has not been performed. Objective This study aimed to evaluate the diagnostic test accuracy of the 3D-CAM in delirium detection through a systematic review and meta-analysis. Methods We systematically searched PubMed, EMBASE, the Cochrane Library, Web of Science, CINAHL (EBSCO) and ClinicalTrials.gov published from inception to 10 July 2022. The quality assessment of the diagnostic accuracy studies-2 tool was applied to evaluate methodological quality. A bivariate random effects model was used to pool sensitivity and specificity. Results Seven studies with 1,350 participants and 2,499 assessments were included, which were carried out in general medical wards, intensive care units, internal medical wards, surgical wards, recovery rooms and post-anaesthesia care units. The prevalence of delirium ranged from 9.1% to 25%. The pooled sensitivity and specificity were 0.92 (95% confidence interval [CI] 0.87–0.95) and 0.95 (95% CI 0.92–0.97), respectively. The pooled positive likelihood ratio was 18.6 (95% CI 12.2–28.2), the negative likelihood ratio was 0.09 (95% CI 0.06–0.14) and the diagnostic odds ratio was 211 (95% CI 128–349). Moreover, the area under the curve was 0.97 (95% CI 0.95–0.98). Conclusions The 3D-CAM has good diagnostic accuracy for delirium detection in different care settings. Further analyses illustrated that it had comparable diagnostic accuracy in older adults and patients with dementia or known baseline cognitive impairment. In conclusion, the 3D-CAM is recommended for clinical delirium detection. [ABSTRACT FROM AUTHOR]

Background Gait impairment contributes to falls and frailty. Some studies suggest that cerebral small vessel disease (CSVD) is associated with gait impairment in the general population. We systematically reviewed and meta-analysed the literature on associations of CSVD with gait impairment and falls. Methods The protocol was published in PROSPERO (CRD42021246009). Searches of Medline, Cochrane and Embase databases were conducted on 30 March 2022. Cross-sectional and longitudinal studies of community-dwelling adults were included, reporting relationships between diagnosis or neuroimaging markers of CSVD and outcomes related to gait or falls. Partial correlation coefficients were calculated and pooled using a random-effects model for meta-analysis. Results The search retrieved 73 studies (53 cross-sectional; 20 longitudinal). Most studies reported an association between CSVD and gait impairments or falls risk: 7/7 studies on CSVD score or diagnosis, 53/67 studies on white matter hyperintensities (WMHs), 11/21 studies on lacunar infarcts, 6/15 studies on cerebral microbleeds and 1/5 studies on perivascular spaces. Meta-analysis of 13 studies found that higher WMH volume was mildly correlated with lower gait speed, in all studies (r  = −0.23, 95% confidence interval: −0.33 to −0.14, P  < 0.0001). However, there was significant heterogeneity between studies (I 2 = 82.95%; tau2 = 0.02; Q  = 79.37, P  < 0.0001), which was unexplained by variation in age, sex, study quality or if the study adjusted for age. Conclusions Findings suggest that CSVD severity is associated with gait impairment, history of falls and risk of future falls. Prevention of CSVD should be part of a comprehensive public health strategy to improve mobility and reduce risk of falls in later life. [ABSTRACT FROM AUTHOR]

Background An optimal antithrombotic strategy for patients aged 80 years or older with atrial fibrillation (AF) remains elusive. Objective Using a systematic review with traditional and network meta-analysis, we investigated outcomes in AF patients ≥80 years treated with different antithrombotic strategies. Methods We searched eligible randomised controlled trials (RCTs) and observational studies from MEDLINE, EMBASE, Cochrane Library and Web of Science databases from inception to 16 December 2021. Research comparing treatment outcomes of novel oral anticoagulants (NOACs), aspirin, vitamin K antagonists (VKAs) or no oral anticoagulant/placebo therapy in patients ≥80 years with AF were included. Outcomes were stroke or systemic embolism (SSE), major bleeding, all-cause mortality, intracranial bleeding (ICH) and gastrointestinal bleeding. Traditional and network meta-analyses were performed. Net clinical benefit integrating SSE and major bleeding was calculated. Results Fifty-three studies were identified for analysis. In the meta-analysis of RCTs, risk of SSE (risk ratio [RR]: 0.82; 95% confidence interval [CI]: 0.73–0.99) and ICH (RR: 0.38; 95% CI: 0.28–0.52) was significantly reduced when NOACs were compared with VKAs. Network meta-analysis of RCTs demonstrated that edoxaban (P -score: 0.8976) and apixaban (P -score: 0.8528) outperformed other antithrombotic therapies by showing a lower major bleeding risk and better net clinical benefit. Both traditional and network meta-analyses from RCTs combining with observational studies showed consistent results. Conclusions In patients aged 80 years or older with AF, NOACs have better outcomes than VKAs regarding efficacy and safety profiles. Edoxaban and apixaban may be preferred treatment options since they are safer than other antithrombotic strategies. [ABSTRACT FROM AUTHOR]

Objective: osteoarthritis is a leading cause of disability. This systematic review aimed to establish the prevalence of depressive symptoms and anxiety among people with osteoarthritis in comparison to those without osteoarthritis. Method: we systematically reviewed databases including AMED, EMBASE, MEDLINE, PsycINFO, BNI, CINAHL and the Cochrane database library from their inception to January 2015. Studies presenting data on depressive symptoms and anxiety in people with osteoarthritis were included. A random- and fixed-effect meta-analysis was conducted on all eligible data. Results: a total of 49 studies were included, representing 15,855 individuals (59% women; mean age 65.2 years). The evidence base was moderate in quality. The pooled prevalence of depressive symptoms in osteoarthritis was 19.9% (95% confidence intervals (CI): 15.9-24.5%, n = 10,811). The corresponding pooled prevalence was 21.3% (95% CI: 15.5-28.5%; n=1,226) for anxiety symptoms. The relative risk of depression among people with osteoarthritis was 1.17 (95% CI 0.69-2.00, three studies, n = 941) compared with people without osteoarthritis. The relative risk of anxiety was 1.35 (95% CI: 0.51-3.59; three studies, n = 733) compared with those without osteoarthritis. Conclusion: one-fifth of people with osteoarthritis experience symptoms of depression and anxiety. However, it is uncertain whether this is increased compared with those without osteoarthritis, with no direct evidence to support an increase in anxiety and depression in osteoarthritis.

Background older adults living in long-term care (LTC) commonly suffer from anxiety symptoms and disorders. We completed a systematic review and meta-analysis to identify efficacious treatments for anxiety symptoms for older adults living in LTC. Methods we searched five electronic databases (MEDLINE, Embase, PsycINFO, Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials) to identify treatments for anxiety that have been trialled in LTC. Included studies had to be randomised trials, include residents of LTC, and measure anxiety symptoms as an outcome. Results the electronic search returned 6,617 articles, 519 were reviewed in full text, and 80 were included in the descriptive synthesis. Limited studies were meta-analysed (n  = 10) due to differences in described treatment and comparator conditions. Limited clinically relevant evidence supporting the use of pharmacologic treatments for symptoms of anxiety in LTC was identified. Of the treatments trialled, music compared with usual care (standardised mean difference, SMD: −0.82; 95% confidence interval (CI): −1.31, −0.34), music compared with social interaction (SMD: −0.41; 95% CI: −0.72, −0.10) and massage compared with usual care (SMD: −4.32; 95% CI: −7.44, −1.19) were found to improve anxiety symptoms, however, significant heterogeneity was detected in two comparisons. Conclusions a range of non-pharmacologic treatments that improved anxiety symptoms were identified for use in LTC. Although limited evidence exists to support the use of particular treatments, most non-pharmacologic treatments were low-risk interventions that may be readily implemented. Further research is required to assess the treatment effect on residents of LTC with anxiety disorders or clinically relevant symptoms at baseline. [ABSTRACT FROM AUTHOR]

Objective Exercise prevents falls in the general older population, but evidence is inconclusive for older adults living with cognitive impairment. We performed an updated systematic review and meta-analysis to assess the potential effectiveness of interventions for reducing falls in older persons with cognitive impairment. Methods PubMed, EMBASE, CINAHL, Scopus, CENTRAL and PEDro were searched from inception to 10 November 2020. We included randomised controlled trials (RCTs) that evaluated the effects of physical training compared to a control condition (usual care, waitlist, education, placebo control) on reducing falls among community-dwelling older adults with cognitive impairment (i.e. any stage of Alzheimer's disease and related dementias, mild cognitive impairment). Results We identified and meta-analysed nine studies, published between 2013 and 2020, that included 12 comparisons (N = 1,411; mean age = 78 years; 56% women). Overall, in comparison to control, interventions produced a statistically significant reduction of approximately 30% in the rate of falls (incidence rate ratio = 0.70; 95% CI, 0.52-0.95). There was significant between-trial heterogeneity (I2 = 74%), with most trials (n = 6 studies [eight comparisons]) showing no reductions on fall rates. Subgroup analyses showed no differences in the fall rates by trial-level characteristics. Exercise-based interventions had no impact on reducing the number of fallers (relative risk = 1.01; 95% CI, 0.90–1.14). Concerns about risk of bias in these RCTs were noted, and the quality of evidence was rated as low. Conclusions The positive statistical findings on reducing fall rate in this meta-analysis were driven by a few studies. Therefore, current evidence is insufficient to inform evidence-based recommendations or treatment decisions for clinical practice. PROSPERO Registration number: CRD42020202094.

Background pain is prevalent in frail older adults; however, the association of pain and frailty has not been evaluated yet by a systematic assessment of prospective longitudinal studies. Objective we aimed to assess the association of persistent pain as a risk factor for frailty incidence, using data from longitudinal studies in a systematic review and meta-analysis. Methods publications were identified using a systematic search on PubMed, Embase, Cochrane Library and clinicaltrials.gov databases from inception to October 2017. Since heterogeneity across studies was high, we used random-effects meta-analysis to calculate the pooled relative risk for the association between persistent pain and the incidence of frailty. We investigated sources of heterogeneity among studies using meta-regression and stratified analyses. Results we included five prospective longitudinal studies with 13,120 participants (46% women, mean age from 59 to 85 years old). Participants with persistent pain at baseline had twice the risk of developing frailty during the follow-up (pooled RR = 2.22, 95% CI = 1.14–4.29). No variables were related to study heterogeneity in sensitivity analyses. Conclusion persistent pain was a risk factor for the development of frailty in a meta-analysis of longitudinal studies. Better understanding of the association between pain and frailty with proper evaluation of potential confounders could allow the development of targeted interventions. [ABSTRACT FROM AUTHOR]

Objective: health-related quality of life (HRQOL) and mental well-being are associated with healthy ageing. Physical activity positively impacts both HRQOL and mental well-being. Yoga is a physical activity that can be modified to suits the needs of older people and is growing in popularity. We conducted a systematic review with meta-analysis to determine the impact of yoga-based exercise on HRQOL and mental well-being in people aged 60+. Methods: searches were conducted for relevant trials in the following electronic databases; MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, Allied and Complementary Medicine Database, PsycINFO and the Physiotherapy Evidence Database (PEDro) from inception to January 2017. Trials that evaluated the effect of physical yoga on HRQOL and/or on mental well-being in people aged 60+ years were included. Data on HRQOL and mental well- being were extracted. Standardised mean differences and 95% confidence intervals (CI) were calculated using random effects models. Methodological quality of trials was assessed using the PEDro scale. Results: twelve trials of high methodological quality (mean PEDro score 6.1), totalling 752 participants, were identified and provided data for the meta-analysis. Yoga produced a medium effect on HRQOL (Hedges' g = 0.51, 95% CI 0.25-0.76, 12 trials) and a small effect on mental well-being (Hedges' g = 0.38, 95% CI 0.15-0.62, 12 trials). Conclusion: yoga interventions resulted in small to moderate improvements in both HRQOL and mental well-being in people aged 60+ years. Further, research is needed to determine the optimal dose of yoga to maximise health impact. PROSPERO registration number: (CRD42016052458) [ABSTRACT FROM AUTHOR]

Background: transcatheter aortic valve replacement (TAVR) provides prognostic benefit for high surgical-risk patients with severe aortic stenosis (AS), yet the impact to patient outcomes is far less understood. Method: we performed a systematic review and meta-analysis to evaluate functional capacity and health-related quality of life (HRQoL) outcomes for patients up to 12 months post TAVR. A total of 20 eligible publications, comprising randomised-controlled trials, observational studies and a registry study were identified from electronic databases, including MEDLINE, EMBASE, Cochrane Library and others (inception to February 2017). Results: the total sample was 2,775 with a mean age of 81.8 ± 2.1 years, more than half (52%) were female and high surgical risk 9.6 ± 4.3% mean STS (Society of Thoracic Surgeons risk model). Post TAVR, patients had significant improvement in functional capacity of >40 m in the 6-minute walk test (6MWT) (95% confidence interval (CI) 9.69-73.28) and a clinically meaningful increase in ability to perform daily physical-based tasks (Duke Activity Status Index (DASI), mean difference (MD) increase 5.42 points, 95% CI 3.16-7.68). HRQoL improved consistently following TAVR regardless of measure used. Significant increases occurred in the physical component summary scores (PCS) of the short form (SF) health surveys (MD increase 10.45 (SF36) and 10.14 (SF12) points). Conclusion: functional capacity and HRQoL improved substantially following TAVR, despite evolving patient selection criteria, thus TAVR continues to provide a directly beneficial option for severe AS patients.

This article discusses a study which examined the effect of non-meat, high protein supplementation on quality of life (QOL) and clinical outcomes for older people living in care homes. Topics covered include the number of older people living in care homes affected by malnutrition, the EMBASE, MEDLINE and the Cochrane Registry of Clinical Trials searched by researchers, and their conclusion that high-protein oral supplements can improve markers of nutritional status in care home residents.

Background: orthostatic hypotension (OH) is one out of many risk factors believed to contribute to an increased fall risk in elderly subjects but it is unclear whether an independent association between OH and falling exists. Objectives: to perform an individual patient data (IPD) meta-analysis of prospective observational studies investigating the relationship between OH and falling. Design: MEDLINE, EMBASE, the Cochrane Library and the abstracts of annual meetings of selected hypertension societies were searched. Both one-stage (analysing all IPD from all studies simultaneously) and two-stage (analysing IPD per study, and then pooling the results) methods were used, and both logistic and cox regression analyses were performed. The study protocol was published on PROSPERO (2015:CRD42015019178). Results: from 34 selected abstracts, 6 studies were included. IPD were provided in 1,022 patients from 3 cohorts and were included in the IPD meta-analysis. The one-stage meta-analysis showed a significant relationship between OH and time to first fall incident (hazard ratio (HR) 1.52 (95% Confidence Interval (CI) 1.23-1.88)). No significant relationship between OH and falling was found in the one-stage logistic regression analysis and the two-stage logistic and cox regression analyses. Conclusions: this IPD meta-analysis of prospective observational studies showed a clear and significant relationship between OH and time to first fall incident. Although the ORs of falling was not significantly different for patients with and without OH, a the cox regression analyses reporting HRs and including time to incident provided more clinically relevant information in present meta-analysis.

Background: older adults are frequent users of emergency services and demonstrate high rates of adverse outcomes following emergency care. Objective: to perform a systematic review and meta-analysis of the Identification of Seniors At Risk (ISAR) screening tool, to determine its predictive value in identifying adults ≥65 years at risk of functional decline, unplanned emergency department (ED) readmission, emergency hospitalisation or death within 180 days after index ED visit/hospitalisation. Methods: a systematic literature search was conducted in PubMed, EMBASE, CINAHL, EBSCO and the Cochrane Library to identify validation and impact analysis studies of the ISAR tool. A pre-specified ISAR score of ≥2 (maximum score 6 points) was used to identify patients at high risk of adverse outcomes. A bivariate random effects model generated pooled estimates of sensitivity and specificity. Statistical heterogeneity was explored and methodological quality was assessed using validated criteria. Results: thirty-two validation studies (n = 12,939) are included. At ≥2, the pooled sensitivity of the ISAR for predicting ED return, emergency hospitalisation and mortality at 6 months is 0.80 (95% confidence interval (CI) 0.70-0.87), 0.82 (95% CI 0.74-0.88) and 0.87 (95% CI 0.75-0.94), respectively, with a pooled specificity of 0.31 (95% CI 0.24-0.38), 0.32 (95% CI 0.24-0.41) and 0.35 (95% CI 0.26-0.44). Similar values are demonstrated at 30 and 90 days. Three heterogeneous impact analysis studies examined the clinical implementation of the ISAR and reported mixed findings across patient and process outcomes. Conclusion: the ISAR has modest predictive accuracy and may serve as a decision-making adjunct when determining which older adults can be safely discharged. [ABSTRACT FROM AUTHOR]

Objective: one-third of community-dwelling older adults fall annually. Exercise that challenges balance is proven to prevent falls. We conducted a systematic review with meta-analysis to determine the impact of yoga-based exercise on balance and physical mobility in people aged 60+ years. Methods: searches for relevant trials were conducted on the following electronic databases: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, Allied and Complementary Medicine Database and the Physiotherapy Evidence Database (PEDro) from inception to February 2015. Trials were included if they evaluated the effect of physical yoga (excluding meditation and breathing exercises alone) on balance in people aged 60+ years. We extracted data on balance and the secondary outcome of physical mobility. Standardised mean differences and 95% confidence intervals (CI) were calculated using random-effects models. Methodological quality of trials was assessed using the 10-point Physiotherapy Evidence Database (PEDro) Scale. Results: six trials of relatively high methodological quality, totalling 307 participants, were identified and had data that could be included in a meta-analysis. Overall, yoga interventions had a small effect on balance performance (Hedges'g= 0.40, 95% CI 0.15-0.65, 6 trials) and a medium effect on physical mobility (Hedges'g = 0.50, 95% CI 0.06-0.95, 3 trials). Conclusion: yoga interventions resulted in small improvements in balance and medium improvements in physical mobility in people aged 60+ years. Further research is required to determine whether yoga-related improvements in balance and mobility translate to prevention of falls in older people. PROSPERO Registration number CRD42015015872.

Objective: we conducted a systematic review to determine the effect of cognitive motor interference (CMI) for the prevention of falls in older adults.Methods: we searched studies through Medline, Embase, the Cochrane Library, Web of Science, CINAHL, PEDro and the China Biology Medicine disc. Only randomised controlled trials examining the effects of CMI for older people were included. The primary outcome measure was falls; the secondary outcome measures included gait, balance function and reaction time.Results: a total of 30 studies of 1,206 participants met the inclusion criteria, and 27 studies of 1,165 participants were used as data sources for the meta-analyses. The pooling revealed that CMI was superior to control group for fall rate [standard mean difference (SMD) (95% CI) = −3.03 (−4.33, −1.73), P < 0.0001], gait speed [SMD (95% CI) = 0.36 (0.07, 0.66), P = 0.01], step length [SMD (95% CI) = 0.48 (0.16, 0.80), P = 0.003], cadence [SMD (95% CI) = 0.19 (0.01, 0.36), P = 0.03], timed up and go test [SMD (95% CI) = −0.22 (−0.38, −0.06), P = 0.007], centre of pressure displacement [SMD (95% CI) = −0.32 (−1.06, 0.43), P = 0.04] and reaction time [SMD (95% CI) = −0.47 (−0.86, −0.08), P = 0.02].Conclusion: the systematic review demonstrates that CMI is effective for preventing falls in older adults in the short term. However, there is, as yet, little evidence to support claims regarding long-term benefits. Hence, future studies should investigate the long-term effectiveness of CMI in terms of fall prevention in older adults. [ABSTRACT FROM PUBLISHER]
