Limits of stability and falls during a multicomponent exercise program in faller older adults: A retrospective cohort study.

BACKGROUND/OBJETIVES: Multicomponent exercise programs have been demonstrated to prevent falls in older adults. However, the underlying responsible mechanisms are not clear. We aimed to analyze the association between changes in the limits of stability (LOS) as a relevant balance component, and falls occurrence during a multicomponent physical exercise program. METHODS: Retrospective study, including ninety-one participants who had experienced a fall in the previous year, and were attended in a falls unit. All of them were included in a twice-a-week multicomponent exercise program during 16 weeks. Pre- and post-program measurements were collected for leg press, gait speed, the short physical performance battery (SPPB), and LOS (point of excursion [POE] and maximal excursion [MEX]) with posturography. Falls occurrence was assessed between the beginning and the completion of the exercise program (16 week). RESULTS: The mean age was 77.2 years, and 72 were female. Thirty-two participants fell at least once during the exercise period. The global baseline POE was 47.6 %, and the MEX was 64.7 %, and there were no differences between fallers and nonfallers. Nonfallers presented greater improvements in POE (6.3 % versus 1.3 %; p < .05) and MEX (9.2 % versus 3.0 %; p < .01) than fallers. The POE and MEX were independently associated with a reduced probability of having had a fall, OR: 0.95 (95 % CI: 0.91 to 0.99) and 0.94 (95 % CI: 0.90 to 0.99), respectively. Changes in SPPB results or leg press strength were not associated with decreased falls. Adjusted probability of fall occurrence decreased by 5 % and 6 % per 1 % improvement in absolute values in POE and MEX, respectively. CONCLUSIONS: Improvements in LOS after a multicomponent physical exercise program in older adults with previous falls may be associated with a decreased occurrence of falls.

Psychological and Functional Impact of COVID-19 in Long-Term Care Facilities: The COVID-A Study.

OBJECTIVE: To analyze the psychological and functional sequelae of the COVID-19 pandemic among older adults living in long term care facilities (LTCFs). DESIGN: Cohort longitudinal study SETTING ANT PARTICIPANTS: A total of 215 residents ≥ 65 years without moderate-to-severe cognitive impairment, living in five LTCFs in Albacete (Spain). MEASUREMENTS: Baseline on-site data were collected between March - June 2020 and three-month follow-up between June to September 2020. Symptoms of depression, anxiety, posttraumatic stress disorder (PTSD), and sleep disturbances were measured as psychological variables. Disability in basic activities of daily living (BADL), ambulation and frailty were assessed as functional variables. Differences were analyzed in relation to level of comorbidity and test positivity for COVID-19. RESULTS: At baseline, residents with COVID-19 presented worse functionality, higher frailty levels and malnutrition risk compared to non-COVID-19 residents. At three-month follow-up, higher rates of clinically significant depressive symptoms (57.7%), anxiety symptoms (29.3%), PTSD symptoms (19.1%) and sleep disturbances (93.0%) were found among residents regardless of COVID status. Thus, among 215 residents, 101 (47%) experienced a decline in BADL from baseline to the 3-month follow-up (median functional loss = 5 points in Barthel Index). In multivariate analyses, COVID-19 status did not explain either the functional or the ambulation loss. By contrast, residents with low comorbidity and COVID-19 presented higher PTSD symptoms (effect 2.58; 95% CI 0.93 to 4.23) and anxiety symptoms (effect 2.10; 95% CI 0.48 to 3.73) compared to the low comorbidity/non-COVID19 group. CONCLUSION: COVID-19 pandemic was associated, after three-months, with high psychological impact in older adults in LTCFs., specifically with higher post-traumatic stress and anxiety symptoms. Functional decline did not differ in relation to COVID-19 status but could be related to isolation strategies used for pandemic control.

Gait plasticity impairment as an early frailty biomarker.

BACKGROUND/OBJECTIVES: To assess whether gait plasticity and gait reserve, valid measures of gait adaptation to environmental stressors, are associated with frailty. DESIGN: Cross-sectional sub-analysis of the FISTAC study (Identification of the Physical Attributes of the Fear of Falling Syndrome). SETTING: Community-dwelling women from the Falls Unit of a Geriatrics Department. PARTICIPANTS: One hundred and twenty-nine women with an age ≥ 70 years old and presence of at least one previous fall in the last year. MEASURES: Age, comorbidity, nutritional status, cognitive status, depression, medications, disability, fear of falling, physical function, hand grip strength, 1RM leg-press strength, maximum and mean leg-press power were determined. Frailty was assessed using the frailty phenotype criteria. Gait plasticity parameters were measured by walking at normal pace, fast pace, and slow pace, and mean (left and right) stride velocity and stride variability (SD) for the three walks were determined independently and for the sum of the three walks. Gait reserve was calculated as the difference in stride velocity from normal to fast pace. ROC curves were constructed to determine the best association between gait plasticity parameters and frailty. RESULTS: The mean age of the participants was 79 years (SD 8.0). The median of normal, fast, slow and three-walks pace stride velocity were 68.9 cm/s (interquartile range [IQR 33.8]), 96.1 cm/s (IQR 38.3), 51.6 cm/s (IQR 19.8), and 72.7 cm/s (IQR 20.7) respectively. The median of normal, fast, slow and three-walks pace stride variability were 4.5 cm/s (IQR 3.3), 5.4 cm/s (IQR 3.8), 3.6 cm/s (IQR 2.3) and 15.9 cm/s (IQR 16.5) respectively. The median of gait reserve was 23 cm/s (IQR 46). Gait reserve and fast pace stride velocity were associated not only with frailty, but also with a lower age, disability, depression, physical function, muscle strength and power, and fear of falling, more than gait velocity. Areas under the curve (95% CI) for gait parameters with stronger association with frailty were fast pace stride velocity 0.801 (0.723-0.880), three-walk mean stride velocity 0.761 (0.678-0.845), three-walks stride variability 0.724 (0.635-0.81) and gait reserve 0.727 (0.635-0.818). CONCLUSIONS: Lower gait reserve and lower gait plasticity have a stronger association with frailty than gait speed in older women. Our results may support the use of these gait parameters to early identify frailty in community-dwelling older women.

COVID-19 outbreak in long-term care facilities from Spain. Many lessons to learn.

BACKGROUND/OBJECTIVES: To analyze mortality, costs, residents and personnel characteristics, in six long-term care facilities (LTCF) during the outbreak of COVID-19 in Spain. DESIGN: Epidemiological study. SETTING: Six open LTCFs in Albacete (Spain). PARTICIPANTS: 198 residents and 190 workers from LTCF A were included, between 2020 March 6 and April 5. Epidemiological data were also collected from six LTCFs of Albacete for the same period of time, including 1,084 residents. MEASUREMENTS: Baseline demographic, clinical, functional, cognitive and nutritional variables were collected. 1-month and 3-month mortality was determined, excess mortality was calculated, and costs associated with the pandemics were analyzed. RESULTS: The pooled mortality rate for the first month and first three months of the outbreak were 15.3% and 28.0%, and the pooled excess mortality for these periods were 564% and 315% respectively. In facility A, the percentage of probable COVID-19 infected residents were 33.6%. Probable infected patients were older, frail, and with a worse functional situation than those without COVID-19. The most common symptoms were fever, cough and dyspnea. 25 residents were transferred to the emergency department, 21 were hospitalized, and 54 were moved to the facility medical unit. Mortality was higher upon male older residents, with worse functionality, and higher comorbidity. During the first month of the outbreak, 65 (24.6%) workers leaved, mainly with COVID-19 symptoms, and 69 new workers were contracted. The mean number of days of leave was 19.2. Costs associated with the COVID-19 in facility A were estimated at € 276,281/month, mostly caused by resident hospitalizations, leaves of workers, staff replacement, and interventions of healthcare professionals. CONCLUSION: The COVID-19 pandemic posed residents at high mortality risk, mainly in those older, frail and with worse functional status. Personal and economic costs were high.

Mapping Associations Between Gait Decline and Fall Risk in Mild Cognitive Impairment.

OBJECTIVES: Compared to their cognitively healthy counterparts, older adults with mild cognitive impairment (MCI) exhibit higher risk of falls, specifically with injuries. We sought to determine whether fall risk in MCI is associated with decline in higher-level brain gait control. DESIGN: Longitudinal study. SETTING: Community-dwelling adults from the Gait and Brain Study Cohort. PARTICIPANTS: A total of 110 participants, aged 65 years or older, with MCI. MEASUREMENTS: Biannual assessments for medical characteristics, cognitive performance, fall incidence, and gait performance for up to 7 years. Seven spatiotemporal gait parameters, including variabilities, were recorded using a 6-meter electronic walkway. Principal components analysis was used to identify independent gait domains related to higher-level (pace and variability domains) and lower-level (rhythm domain) brain control. Associations between gait decline and incident falls were studied with Cox regression models adjusted for baseline covariates. RESULTS: Of participants enrolled, 40% experienced at least one fall (28% of them with injuries) over a mean follow-up of 31.6 ± 23.9 months. From the pace domain, slower gait speed (adjusted hazard ratio [aHR] per 10-cm/s decrease = 4.62; 95% confidence interval [CI] = 1.84-11.61; P = .001) was associated with severe injurious falls requiring emergency room (ER) visit; from the variability domain, stride time variability (aHR per 10% increase during follow-up = 2.17; 95% CI = 1.02-4.63; P = .04) was associated with higher risk of all injurious falls. Rhythm domain was not associated with fall risk. Decline in pace domain was significantly associated with falls with ER visit (aHR = 3.67; 95% CI = 1.46-9.19; P = .005). After adjustments for multiple comparisons, gait speed and pace domain remained significantly associated with falls with ER visits. No statistically significant associations were found between gait domains and overall falls (P ≥ .06). CONCLUSION: Higher risk of injurious falls in older adults with MCI is associated with decline in gait parameters related to higher-level brain control. J Am Geriatr Soc 68:576-584, 2020.

[Oral anticoagulation therapy in the elderly population with atrial fibrillation. A review article]. / Anticoagulación en población anciana con fibrilación auricular no valvular. Artículo de revisión.

Aging is an important risk factor for patients with atrial fibrillation. The estimated prevalence of atrial fibrillation in patients aged ≥80 years is 9-10%, and is associated with a four to five fold increased risk of embolic stroke, and with an estimated increased stroke risk of 1.45-fold per decade in aging. Older age is also associated with an increased risk of major bleeding with oral anticoagulant therapy. This review will focus on the role of oral anticoagulation with new oral anticoagulants, non-vitamin K antagonist in populations with common comorbid conditions, including age, chronic kidney disease, coronary artery disease, on multiple medication, and frailty. In patients 75 years and older, randomised trials have shown new oral anticoagulants to be as effective as warfarin, or in some cases superior, with an overall better safety profile, consistently reducing rates of intracranial haemorrhages. Prior to considering oral anticoagulant therapy in an elderly frail patient, a comprehensive assessment should be performed to include the risks and benefits, stroke risk, baseline kidney function, cognitive status, mobility and fall risk, multiple medication, nutritional status assessment, and life expectancy.

Benefits of a multicomponent Falls Unit-based exercise program in older adults with falls in real life.

BACKGROUND/OBJECTIVES: Multicomponent exercise programs are the cornerstone in preventing gait and balance impairments and falls in older adults. However, the effects of these programs in usual clinical practice have been poorly analyzed. DESIGN: 4-Month, twice-a-week multicomponent exercise program cohort study in real-life. SETTING: Falls Unit, Complejo Hospitalario Universitario of Albacete, Spain. PARTICIPANTS: Sixty-seven participants who had experienced a fall in the previous year were included. MEASUREMENTS: Pre- and post-intervention measurements were collected for leg press, gait speed, the Short Physical Performance Battery (SPPB), the Falls Efficiency Scale International, fat mass percentage, body mass index, the Geriatric Depression Scale by Yesavage (GDS), the Mini Mental State Examination, and the number of falls. RESULTS: Fifty participants completed the program (adherence rate 75%, attendance 80%). Their mean age was 77.2 (SD 5.8) years; 39 were women. The participants reduced the mean number of frailty criteria from 2.1 to 1.3 (95%CI 0.4-1.1) and increased mean gait speed from 0.65 m/s to 0.82 m/s (95%CI 0.11-0.22), increasing their median SPPB scores from 8.5 to 10.0 points (p < 0.001), leg press strength from 62.5 kg to 80.0 kg (p < 0.001), and leg press power at 60% load from 76 W to 119 W (p < 0.001). There was also an improvement in GDS scores from 5.3 to 4.4 (95%CI 0.1-1.7). Body mass index did not change, but fat-free mass increased from 43.7 kg to 44.2 kg (95%CI 0.1-1.0), and fat mass percentage declined from 36.7% to 36.0% (95% CI 0.1-1.4). Seventeen patients (34%) had a fall during the six-month follow-up, and there was a reduction in the median number of falls from 3.0/year to 0.0/six months. CONCLUSIONS: A multicomponent Falls Unit-based exercise program as part of usual clinical practice in real life, improved physical function, reduced depressive symptoms, improved body composition and decreased the number of falls in older adults with previous falls.

Fragilidad como predictor de mortalidad, discapacidad incidente y hospitalización a largo plazo en ancianos españoles. Estudio FRADEA / Frailty and long term mortality, disability and hospitalisation in Spanish older adults. The FRADEA Study

Introducción. El objetivo de nuestro trabajo fue analizar si la fragilidad se asocia a largo plazo con mortalidad, discapacidad incidente en actividades básicas de la vida diaria (ABVD) y hospitalización. Material y métodos. Estudio de cohortes concurrente sobre 993 mayores de 70 años incluidos en el estudio FRADEA. La fragilidad se midió mediante el fenotipo de Fried. Durante el seguimiento se registraron mortalidad, hospitalización y discapacidad incidente en ABVD (baño, aseo, vestido, retrete, transferencias y comer). El riesgo de presentar dichos eventos adversos se determinó mediante regresión logística, Kaplan-Meier y análisis de riesgos proporcionales de Cox ajustado por edad, sexo, Barthel basal, comorbilidad e institucionalización. Resultados. El tiempo medio de seguimiento fue de 952 días (DE 408) durante los cuales fallecieron 182 sujetos (18,4%). Los participantes frágiles tuvieron mayor riesgo ajustado de mortalidad (HR 4,5; IC 95%: 1,8-11,1), discapacidad incidente en ABVD (OR 2,7; IC 95%: 1,3-5,9) y del evento combinado mortalidad o discapacidad incidente (OR 3,0; IC 95%: 1,5-6,1). Los prefrágiles tuvieron mayor riesgo ajustado de mortalidad (HR 2,9; IC 95%: 1,2-6,5), discapacidad incidente (OR 2,1; IC 95%: 1,2-3,6) y del evento combinado mortalidad o discapacidad incidente (OR 2,2; IC 95%: 1,3-3,6). Se observó una asociación positiva entre fragilidad y hospitalización que quedó al borde de la significación (OR 1,7; IC 95%: 1,0-3,0). Conclusiones. El estado de fragilidad se asocia a largo plazo con mortalidad y discapacidad incidente en ABVD en una cohorte de ancianos españoles (AU)

Introduction. The objective of this study was to analyse whether frailty is related to long-term mortality, incident disability in basic activities of daily living (BADL), and hospitalisation. Material and methods. A concurrent cohort study conducted on 993 participants over age 70 from the FRADEA Study. Frailty was determined with Fried frailty phenotype. Data was collected on mortality, hospitalisation and incident disability in BADL (bathing, grooming, dressing, toileting, eating or transferring) during the follow-up period. The risk of adverse events was determined by logistic regression, Kaplan-Meier analysis, and Cox proportional hazard analysis adjusted for age, sex, Barthel index, comorbidity and institutionalization. Results. Mean follow-up was 952 days (SD 408), during which 182 participants (18.4%) died. Frail participants had an increased adjusted risk of death (HR 4.5, 95%CI: 1.8-11.1), incident disability in BADL (OR 2.7, 95%CI: 1.3-5.9) and the combined event mortality or incident disability (OR 3.0, 95%CI: 1.5-6.1). Pre-frail subjects had an increased adjusted risk of death (HR 2.9, 95%CI: 1.2-6.5), incident disability in BADL (OR 2.1, 95%CI: 1.2-3.6), and the combined event mortality or incident disability (OR 2.2, 95%CI: 1.3-3.6). There was a positive association between frailty and hospitalisation, which almost reached statistical significance (OR 1.7, 95%CI: 1.0-3.0). Conclusions. Frailty is long-term associated with mortality and incident disability in BADL in a Spanish cohort of older adults (AU)
