The association between low skeletal muscle mass and delirium: results from the nationwide multi-centre Italian Delirium Day 2017.

INTRODUCTION: Delirium and sarcopenia are common, although underdiagnosed, geriatric syndromes. Several pathological mechanisms can link delirium and low skeletal muscle mass, but few studies have investigated their association. We aimed to investigate (1) the association between delirium and low skeletal muscle mass and (2) the possible role of calf circumference mass in finding cases with delirium. METHODS: The analyses were conducted employing the cross-sectional "Delirium Day" initiative, on patient 65 years and older admitted to acute hospital medical wards, emergency departments, rehabilitation wards, nursing homes and hospices in Italy in 2017. Delirium was diagnosed as a 4 + score at the 4-AT scale. Low skeletal muscle mass was operationally defined as calf circumference ≤ 34 cm in males and ≤ 33 cm in females. Logistic regression models were used to investigate the association between low skeletal muscle mass and delirium. The discriminative ability of calf circumference was evaluated using non-parametric ROC analyses. RESULTS: A sample of 1675 patients was analyzed. In total, 73.6% of participants had low skeletal muscle mass and 24.1% exhibited delirium. Low skeletal muscle mass and delirium showed an independent association (OR: 1.50; 95% CI 1.09-2.08). In the subsample of patients without a diagnosis of dementia, the inclusion of calf circumference in a model based on age and sex significantly improved its discriminative accuracy [area under the curve (AUC) 0.69 vs 0.57, p < 0.001]. DISCUSSION AND CONCLUSION: Low muscle mass is independently associated with delirium. In patients without a previous diagnosis of dementia, calf circumference may help to better identify those who develop delirium.

Rehabilitation in adult post-COVID-19 patients in post-acute care with Therapeutic Exercise.

COVID-19 patients may experience disability related to Intensive Care Unit (ICU) admission or due to immobilization. We assessed pre-post impact on physical performance of multi-component therapeutic exercise for post-COVID-19 rehabilitation in a post-acute care facility. A 30-minute daily multicomponent therapeutic exercise intervention combined resistance, endurance and balance training. Outcomes: Short Physical Performance Battery; Barthel Index, ability to walk unassisted and single leg stance. Clinical, functional and cognitive variables were collected. We included 33 patients (66.2±12.8 years). All outcomes improved significantly in the global sample (p<0.01). Post-ICU patients, who were younger than No ICU ones, experienced greater improvement in SPPB (4.4±2.1 vs 2.5±1.7, p<0.01) and gait speed (0.4±0.2 vs 0.2±0.1 m/sec, p<0.01). In conclusion, adults surviving COVID-19 improved their functional status, including those who required ICU stay. Our results emphasize the need to establish innovative rehabilitative strategies to reduce the negative functional outcomes of COVID-19.

The role of physical exercise and rehabilitation in delirium.

PURPOSE: This article aims to analyze the intersections between delirium, physical exercise and rehabilitation, to better understand their interrelation and to visualize future lines of research. METHODS: In this narrative review, after an overview of brain neurophysiology and function, as common substrates to understand the relationship between delirium and physical function, we explore the scientific evidence in: (1) physical dysfunction as a risk factor for delirium; (2) physical dysfunction as a symptom of delirium and (3) functional consequences related to delirium. Later, we analyze the physical therapy as one of the main strategies in multicomponent interventions to prevent delirium, by examining intervention studies including rehabilitation, which have shown to be effective in managing delirium. Finally, we analyze how frailty, delirium and physical exercise interact with each other. RESULTS: This review confirms the close relationship between delirium and physical dysfunction; therefore, it is not surprising that physical exercise is widely used in delirium preventive strategies. Although delirium is catalogued as a neurocognitive disorder, scientific evidence shows that it is also a motor disorder, which is to be expected, since a vast body of literature already supports an interaction between motor and cognitive function. CONCLUSION: The motor component of delirium should be taken into account when designing interventions or strategies to address delirium. These interventions may have a special importance in frail older adults.

A Community Program of Integrated Care for Frail Older Adults: +AGIL Barcelona.

OBJECTIVES: To assess the 3-month impact on physical function of a program for community-dwelling frail older adults, based on the integration of primary care, geriatric medicine, and community resources, implemented in "real life". DESIGN: Interventional cohort study. SETTING: Primary care in Barcelona, Spain. PARTICIPANTS: Individuals aged ≥80 years (n=134), presenting at least one sign of frailty (i.e., slow gait speed, weakness, memory complaints, involuntary weight loss, poor social support). INTERVENTION: After frailty screening by the primary care team, candidates were referred to a geriatric team (geriatrician + physical therapist), who performed a comprehensive geriatric assessment and designed a tailored multidisciplinary intervention in the community, including a) multi-modal physical activity (PA) sessions, b) promotion of adherence to a Mediterranean diet c) health education and d) medication review. MEASUREMENTS: Participants were assessed based on a comprehensive geriatric assessment including physical performance (Short Physical Performance Battery -SPPB- and gait speed), at baseline and at a three month follow-up. RESULTS: A total of 112 (83.6%) participants (mean age=80.8 years, 67.9% women) were included in this research. Despite being independent in daily life, participants' physical performance was impaired (SPPB=7.5, SD=2.1, gait speed=0.71, SD=0.20 m/sec). After three months, 90.2% of participants completed ≥7.5 physical activity sessions. The mean improvements were +1.47 (SD 1.64) points (p<0.001) for SPPB, +0.08 (SD 0.13) m/sec (p<0.001) for gait speed, -5.5 (SD 12.10) sec (p<0.001) for chair stand test, and 53% (p<0.001) improved their balance. Results remained substantially unchanged after stratifying the analyses according to the severity of frailty. CONCLUSIONS: Our results suggested that a "real-world" multidisciplinary intervention, integrating primary care, geriatric care, and community services may improve physical function, a marker of frailty, within 3 months. Further studies are needed to address the long-term impact and scalability of this implementation program.

Translation and Validation of the Spanish Version of the SARC-F Questionnaire to Assess Sarcopenia in Older People.

OBJECTIVES: The revised European consensus on sarcopenia definition and diagnosis (EWGSOP2) includes the SARC-F questionnaire, the most valid and consistent sarcopenia screening tool, as the mandatory first step. Our aim was the translation, cross-cultural adaptation, and validation of the SARC-F questionnaire as a culturally-responsive Spanish-language version for the European population. STUDY DESIGN: Cross-sectional descriptive study, applying the two-step WHO methodology for translation and cross-cultural adaptation of health questionnaires, and harmonization with the Mexican-Spanish version. European Union Geriatric Medicine Society recommendations for SARC-F validation in European languages were considered. PARTICIPANTS: Outpatient clinics of a university hospital. INCLUSION CRITERIA: stable, ambulatory (including aids), community-dwelling population ≥65 years old. MAIN OUTCOME MEASURES: The self-reported 5-item SARC-F questionnaire was administered; scores ≥4 indicated sarcopenia. Sensitivity, specificity, accuracy-likelihood ratios, predictive values, and kappa statistics were calculated and consecutively compared with European Working Group on Sarcopenia in Older People (EWGSOP) and EWGSOP2 criteria. RESULTS: This Spanish version, administered in an average 70s, has adequate internal consistency (Cronbach alpha=0.779). For the validation study, 90 (43.3%) of 208 potentially eligible subjects (81.4 ± 5.9 years old, 75.6% women) were included. SARC-F identified 51 (56.7%) subjects with sarcopenia and 39 (43.3%) without the disease. Prevalence was 17.8% per EWGSOP and 25.6% per EWGSOP2 (58% accuracy and fair agreement: sensitivity, 78.3%; specificity, 50.8%). CONCLUSIONS: SARC-F is a feasible tool, suitable for bedside assessment in community-dwelling older patients. Wide diffusion of this culturally-responsible SARC-F Spanish version is expected as EWGSOP2 is adopted and sarcopenia assessment is broadly implemented in Spain.

25(OH) vitamin D and functional outcomes in older adults admitted to rehabilitation units: the safari study.

Vitamin D (25(OH)D) deficiency is associated with poor physical performance; little is known about its impact on geriatric rehabilitation. We found a positive non-linear relationship between 25(OH)D and functional gain, stronger in levels < 16 ng/ml (below the cutoff for "deficiency"). An early 25(OH)D dosage may be advisable for this population. INTRODUCTION: Vitamin D (25(OH)D) deficiency is highly prevalent in older people, and it is associated with poor muscular strength and physical performance. Its impact on functional outcomes during geriatric rehabilitation has been poorly studied. We aim to analyze the association between 25(OH)D and functional recovery in geriatric rehabilitation units. METHODS: We conducted a prospective multi-center cohort study including patients ≥ 65 years old admitted to 3 geriatric rehabilitation units in Italy and Spain, after orthopedic events or stroke. Outcomes were absolute functional gain (AFG, discharge-admission Barthel index) and ability to walk (AW) at 3 months after admission. The association between 25(OH)D quartiles (Q1-Q2-Q3-Q4) and outcomes was explored using linear or logistic regression models. RESULTS: We included 420 patients (mean age = 81.2 years [SD = 7.7], 66.4% females, mean 25(OH)D concentration = 13.5 ng/ml [SD = 8.7]) (to convert to nmol/l multiply by 2.496). A non-linear relationship between 25(OH)D and AFG was found, with a stronger association for 25(OH)D levels < 16 ng/ml. Compared to Q1 (25(OH)D ≤ 6 ng/ml), participants in Q3 (25(OH)D 11.5-18.2 ng/ml) had the best AFG and AW (mean AFG [SD], Q1 = 28.9 [27.8], Q2 = 32.5 [23.5], Q3 = 43.1 [21.9], Q4 = 34.5 [29.3], R2 = 7.3%; AW, Q1-Q2 = 80%, Q3 = 91%, Q4 = 86%). Regression models adjusted for potential confounders confirmed these results (AGF Q2, ß = 2.614, p = 0.49; Q3, ß = 9.723, p < 0.01; Q4, ß = 4.406, p = 0.22; AW Q2, OR [95% CI] = 1.84 [0.67-5.33]; Q3, OR [95% CI] = 4.01 [1.35-13.48]; Q4, OR [95% CI] = 2.18 [0.81-6.21]). CONCLUSIONS: In our study, 25(OH)D concentration showed a positive association with functional outcomes at 3 months. The association is stronger below the usual cutoff for "deficiency." Dosage of 25(OH)D concentration may help identify geriatric rehabilitation patients at risk for a worse functional recovery.

Frailty Related Factors as Predictors of Functional Recovery in Geriatric Rehabilitation: The Sarcopenia And Function in Aging Rehabilitation (SAFARI) Multi-Centric study.

BACKGROUND: Frailty-related characteristics, such as sarcopenia, malnutrition and cognitive impairment, are often overlooked, both in clinical practice and research, as potential contributors to functional recovery during geriatric rehabilitation. OBJECTIVE: The aim of the study was to identify frailty-related characteristics associated with functional recovery in a cohort of post-orthopedic surgery and post-stroke older adults. DESIGN: Multi-centric cohort study. Participanst and Settings: Patients over 65 years, admitted to three geriatric rehabilitation units, in Spain and Italy, after an orthopedic event or a stroke, from December 2014 to May 2016. MEASUREMENTS: The Absolute Functional Gain (AFG) defined as the difference between Barthel Index score at discharge and at admission, and the Relative Functional Gain (RFG) that represents the percentage of recovery of the function lost due to the event, were selected as outcomes. Both outcomes were analyzed as continuous and dichotomous variables. Analyses were also stratified as diagnostic at admission. RESULTS: We enrolled 459 patients (mean age±SD=80.75±8.21 years), 66.2% women, 69.5% with orthopedic conditions and with a length of stay of 28.8±9.1 days. Admission after a stroke (Odds Ratio=0.36, 95% Confidence Interval=0.22-0.59]) and a better functional status at admission (OR=0.96, 95% CI=0.94-0.97), were associated with a lower likelihood of AFG, while a better pre-event Barthel index (OR=1.03 for each point in score, 95% CI=1.01-1.04), being able to walk (OR=2.07, 95% CI=1.16-3.70), and a better cognitive status at admission (OR=1.05, 95% CI=1.01-1.09), were associated with a higher chance of AFG. Post-stroke patients with delirium at admission had a re-duced chance of AFG (OR=0.25, 95% CI=0.07-0.91]). Patients admitted after an ortho-pedic event with better pre-event functional status (OR=1.04, 95% CI=1.02-1.06) and able to walk at admission (OR=2.79, 95% CI=1.29-6.03]) had an increased chance of AFG. Additionally, in both diagnostics groups, a better handgrip strength increased the chance of RFG. CONCLUSIONS: Among frailty-related variables, physical, cognitive and muscular function at admission could be relevant for functional improvement during geriatric reha-bilitation. If confirmed, this data might orient targeted interventions.

The relationship between frailty and polypharmacy in older people: A systematic review.

AIMS: Frailty is a complex geriatric syndrome resulting in decreased physiological reserves. Frailty and polypharmacy are common in older adults and the focus of extensive studies, although little is known about the impact they may have on each other. This is the first systematic review analysing the available evidence on the relationship between frailty and polypharmacy in older adults. METHODS: Systematic review of quantitative studies. A comprehensive literature search for publications in English or Spanish was performed on MEDLINE, CINAHL, the Cochrane Database and PsycINFO in September 2017 without applying restrictions on the date of publication. Studies reporting any relationship between frailty and polypharmacy in older adults were considered. RESULTS: A total of 25 publications were included, all of them observational studies. Evaluation of Fried's frailty criteria was the most common approach, followed by the Edmonton Frail Scale and FRAIL scale. Sixteen of 18 cross-sectional analyses and five of seven longitudinal analyses demonstrated a significant association between an increased number of medications and frailty. The causal relationship is unclear and appears to be bidirectional. Our analysis of published data suggests that polypharmacy could be a major contributor to the development of frailty. CONCLUSIONS: A reduction of polypharmacy could be a cautious strategy to prevent and manage frailty. Further research is needed to confirm the possible benefits of reducing polypharmacy in the development, reversion or delay of frailty.

Cerebrovascular disease and gait and balance impairment in mild to moderate Alzheimer's disease.

OBJECTIVES: Gait and movement abnormalities are traditionally considered infrequent in patients with mild/moderate Alzheimer's disease (AD). However, an increased risk of falls and gait abnormalities has been detected, even in early stages of the disease. Whether these abnormalities are associated with cerebrovascular disease, which has a high prevalence in AD, remains unclear. DESIGN: Cross-sectional study. SETTING: Dementia outpatient clinics. PARTICIPANTS: 24 mild/moderate AD patients with (AD+CVD) and 20 without (AD-CVD) cerebrovascular disease without a history of stroke and antipsychotic medications. MEASUREMENTS: Physical performance, measured with the short physical performance battery [SPPB], a summary measure combining 4-meter gait speed, balance and muscle strength, and with 8-meter gait speed with a turn was compared between the two groups. RESULTS: AD+CVD patients showed a significant higher prevalence of 4-meter gait speed slower than 0.8 m/s (37.5% vs. 5%, p-value=0.01) and balance impairment (37.5% vs. 10%, p-value=0.038), as well as a slower 8-meter gait speed with a turn (mean+SD=0.6±0.2 vs. 0.8±0.2, p-value=0.024). These associations were confirmed in multivariable models. No differences were observed for muscle strength. CONCLUSION: In our sample, AD with cerebrovascular disease had worse gait and balance than AD without cerebrovascular disease. If confirmed, these results may have clinical implications, since cerebrovascular disease can be potentially prevented.

Nutrition in the age-related disablement process.

The transition from independence to disability in older adults is characterized by detectable changes in body composition and physical function. Epidemiologic studies have shown that weight loss, reduced caloric intake and the reduced intake of specific nutrients are associated with such changes. The mechanisms underlying these associations remain unclear, and different hypotheses have been suggested, including the reduction of the antioxidant effects of some nutrients. Changes in muscle mass and quality might play a central role in the pathway linking malnutrition, its biological and molecular consequences, and function. A different approach aims at assessing diets by dietary patterns, which capture intercorrelations of nutrients within a diet, rather than by selective foods or nutrients: epidemiologic evidence suggests that some types of diet, such as the Mediterranean diet, might prevent negative functional outcomes in older adults. However, despite a theoretical and empirical basis, intervention studies using nutritional supplementation have shown inconclusive results in preventing functional impairment and disability. The present work is the result of a review and consensus effort of a European task force on nutrition in the elderly, promoted by the International Association of Gerontology and Geriatrics (IAGG) European Region. After the critical review of different aspects related to the role of nutrition in the transition from independence to disability, we propose future lines for research, including the determination of levels of inadequacy and target doses of supplements, the study of interactions (between nutrients within a diet and with other lifestyle aspects), and the association with functional outcomes.

Is suboptimal prescribing a risk factor for poor health outcomes in community-dwelling elders? The ICARe Dicomano study.

PURPOSE: Mostly because of comorbidity and drugs consumption, older persons are often exposed to an increased risk of sub-optimal prescribing (SP). At present, few studies investigated the association between SP and long-term health outcomes. We examined the relation between SP and the risk of mortality and hospitalization in Italian older community-dwellers. METHODS: Older (65+ years) community-dwelling residents of a small town in Tuscany were enrolled in a longitudinal study. SP was defined as polypharmacy (use of 5+ drugs), prescription of inappropriate drugs (ID) according to Beers' criteria, and of potentially interacting drugs (PID), evaluated in 1995 and 1999. These three forms of SP were entered as time-dependent exposures into multivariable Cox regression analysis models, whose outcomes were mortality and hospitalizations through 2003. RESULTS: Of 1022 participants (mean age 73.0 +/- 6.8, 57% women), 220 were evaluated in 1995, 234 in 1999 and 568 in both waves. In univariate analysis, mortality was two-fold higher in participants with polypharmacy (73.4/1000 person/years, 95% CI 58.2-92.4 vs. 34.1, 95% CI 29.7-39.2; p < 0.001) or PID (72.7/1000 person/years, 95% CI 46.3-113.9 vs. 38.0, 95% CI 33.5-43.1; p < 0.001), whereas it was unrelated to the presence of ID. Hospitalization rates were independent of any form of SP. In multivariable models, polypharmacy, ID, and PID were no longer associated with an increased risk of death, and ID predicted a slightly increased risk of hospitalizations (HR 1.03, 95% CI 1.0-1.06, p = 0.048). CONCLUSIONS: In this cohort, SP was not associated with an excess risk of poor health outcomes.

Gait speed at usual pace as a predictor of adverse outcomes in community-dwelling older people an International Academy on Nutrition and Aging (IANA) Task Force.

INTRODUCTION: The use of a simple, safe, and easy to perform assessment tool, like gait speed, to evaluate vulnerability to adverse outcomes in community-dwelling older people is appealing, but its predictive capacity is still questioned. The present manuscript summarises the conclusions of an expert panel in the domain of physical performance measures and frailty in older people, who reviewed and discussed the existing literature in a 2-day meeting held in Toulouse, France on March 12-13, 2009. The aim of the IANA Task Force was to state if, in the light of actual scientific evidence, gait speed assessed at usual pace had the capacity to identify community-dwelling older people at risk of adverse outcomes, and if gait speed could be used as a single-item tool instead of more comprehensive but more time-consuming assessment instruments. METHODS: A systematic review of literature was performed prior to the meeting (Medline search and additional pearling of reference lists and key-articles supplied by Task Force members). Manuscripts were retained for the present revision only when a high level of evidence was present following 4 pre-selected criteria: a) gait speed, at usual pace, had to be specifically assessed as a single-item tool, b) gait speed should be measured over a short distance, c) at baseline, participants had to be autonomous, community-dwelling older people, and d) the evaluation of onset of adverse outcomes (i.e. disability, cognitive impairment, institutionalisation, falls, and/or mortality) had to be assessed longitudinally over time. Based on the prior criteria, a final selection of 27 articles was used for the present manuscript. RESULTS: Gait speed at usual pace was found to be a consistent risk factor for disability, cognitive impairment, institutionalisation, falls, and/or mortality. In predicting these adverse outcomes over time, gait speed was at least as sensible as composite tools. CONCLUSIONS: Although more specific surveys needs to be performed, there is sufficient evidence to state that gait speed identifies autonomous community-dwelling older people at risk of adverse outcomes and can be used as a single-item assessment tool. The assessment at usual pace over 4 meters was the most often used method in literature and might represent a quick, safe, inexpensive and highly reliable instrument to be implemented.
