"SARCOPENIA MEASURED BY ULTRASOUND IN HOSPITALIZED OLDER ADULTS" (ECOSARC): multi-centre, prospective observational study protocol.

BACKGROUND: Measurement of muscle mass and function, and thereafter, screening and diagnosis of sarcopenia, is a challenge and a need in hospitalized older adults. However, it is difficult in complex real-world old patients, because usually they are unable to collaborate with clinical, functional, and imaging testing. Ultrasound measurement of quadriceps rectus femoris (QRF) provides a non-invasive, real-time assessment of muscle quantity and quality, and is highly acceptable to participants with excellent inter-rater and intra-rater variability. However, normative data, protocol standardization, and association with longitudinal outcomes, needs further research and consensus. METHODS: Prospective exploratory multicenter study in older adults admitted to Acute Geriatric Units (AGUs) for medical reasons. 157 subjects from 7 AGUs of Spain were recruited between May 2019 and January 2022. Muscle ultrasound measurements of the anterior vastus of the QRF were acquired on admission and on discharge, using a previously validated protocol, using a Chieson model ECO2 ultrasound system (Chieson Medical Technologies, Co. Ltd, Wimxu District Wuxi, Jiangsu, China). Measurements included the cross-sectional area, muscle thickness in longitudinal view, intramuscular central tendon thickness, echogenicity, and the presence or absence of edema and fasciculations. Functional, nutritional, and DXA measurements were provided. Clinical follow-up was completed at discharge, and 30 and 90 days after discharge. Variations between hospital admission and discharge ultrasound values, and the relationship with clinical variables, will be analyzed using paired t-tests, Wilcoxon tests, or Mc Nemar chi-square tests when necessary. Prevalence of sarcopenia will be calculated, as well as sensitivity and specificity of ultrasound measurements to determine sarcopenia. Kappa analysis will be used to analyze the concordance between measurements, and sensitivity analysis will be conducted for each participating center. DISCUSSION: The results obtained will be of great interest to the scientific geriatric community to assess the utility and validity of ultrasound measurements for the detection and follow-up of sarcopenia in hospitalized older adults, and its association with adverse outcomes. TRIAL REGISTRATION: NCT05113758. Registration date: November 9th 2021. Retrospectively registered.

Resting metabolic rate in relation to incident disability and mobility decline among older adults: the modifying role of frailty.

BACKGROUND: Alterations in resting metabolic rate (RMR), the largest component of daily total energy expenditure, with aging have been shown in various studies. However, little is known about the associations between RMR and health outcomes in later life. AIMS: To analyze whether RMR is associated with incident disability and mobility decline in a 10-year longitudinal study, as well as the moderating role of frailty in these associations. METHODS: Data from 298 older adults aged 70 and over from the Frailty and Dependence in Albacete (FRADEA) study in Spain were used, including a baseline measurement in 2007-2009 and a follow-up measurement 10 years later. RMR was measured by indirect calorimetry. Outcomes were incident disability in basic activities of daily living (BADL, Barthel Index), incident disability in instrumental ADL (IADL, Lawton index), and mobility decline (Functional Ambulation Categories scores). Fried's frailty phenotype was used as an indicator of frailty. Logistic regression analyses were conducted. RESULTS: Fully adjusted and stratified analyses revealed that only in the pre-frail/frail group, a higher RMR was associated with a lower risk of incident BADL disability (OR = 0.47, 95% CI = 0.23-0.96, p = 0.037), incident IADL disability (OR = 0.39, 95% CI = 0.18-0.84, p = 0.017), and mobility decline (OR = 0.30, 95% CI = 0.14-0.64, p = 0.002). CONCLUSIONS: To our knowledge, this is the first study looking at the associations between RMR and functional health using a longitudinal research design. The results suggest that RMR could be used as an early identifier of a specific resilient group within the pre-frail and frail older population, with a lower risk of further health decline.

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.

Frailty, depression risk and 10-year hospitalization in older adults. The FRADEA study.

OBJECTIVES: To determine whether the interaction between frailty status and depression risk is associated with hospitalization density in older adults. METHODS: Ongoing cohort study in 794 subjects aged over 70 years from Albacete (Spain). Data were collected on depression risk, frailty, hospitalizations, and covariates. Participants were categorized into six groups. RESULTS: Adjusted hospitalization risk was higher for groups of prefrail/-non depression risk (HR 1.48; 95% confidence interval (CI) 1.16-1.89), prefrail/depression risk (HR 1.73; 95% CI 1.29-2.30), frail/non depression risk (HR 1.79; 95% CI 1.22-2.62), and frail/depression risk (HR 2.12; 95% CI 1.49-3.02), compared with robust/non depression risk group (p<0.01). Frail and prefrail groups presented increased hospitalization density in the first four follow-up years. CONCLUSIONS: Depression risk changes the yearly probabilities of hospitalization in prefrail and frail groups, increasing them in the first years. Depression risk should be monitored in prefrail and frail older adults as an independent risk factor for hospitalization.

Frailty, depression risk, and 10-year mortality in older adults: the FRADEA study.

OBJECTIVES: To investigate if depression risk modifies the association between frailty and mortality in older adults. DESIGN: Ongoing cohort study. SETTING: Albacete city, Spain. PARTICIPANTS: Eight hundred subjects, 58.8% women, over 70 years of age from the Frailty and Dependence in Albacete (FRADEA) study. MEASUREMENTS: Frailty phenotype, Geriatric Depression Scale (GDS), comorbidity, disability, and drug use were collected at baseline. Six groups were categorized: (G1: non-frail/no depression risk; G2: non-frail/depression risk; G3: prefrail/no depression risk; G4: prefrail/depression risk; G5: frail/no depression risk; and G6: frail/depression risk). Mean follow-up was 2542 days (SD 1006). GDS was also analyzed as a continuous variable. The association between frailty and depression risk with 10-year mortality was analyzed. RESULTS: Mean age was 78.5 years. Non-frail was 24.5%, prefrail 56.3%, frail 19.3%, and 33.5% at depression risk. Mean GDS score was 3.7 (SD 3.2), increasing with the number of frailty criteria (p < 0.001). Ten-year mortality rate was 44.9%. Mortality was 21.4% for the non-frail, 45.6% for the prefrail, and 72.7% for the frail participants, 56% for those with depression risk, and 39.3% for those without depression risk. Mean survival times for groups G1 to G6 were, respectively, 3390, 3437, 2897, 2554, 1887, and 1931 days. Adjusted mortality risk was higher for groups G3 (HR 2.1; 95% confidence interval (CI) 1.4-3.1), G4 (HR 2.5; 95% CI 1.7-3.8), G5 (HR 3.8; 95% CI 2.4-6.1), and G6 (HR 4.0; 95% CI 2.6-6.2), compared with G1 (p < 0.001). Interaction was found between frailty and depression risk, although they were independently associated with mortality. CONCLUSIONS: Depression risk increases mortality risk in prefrail older adults but not in non-frail and frail ones. Depression should be monitored in these older adults to optimize health outcomes. Factors modulating the relationship between frailty and depression should be explored in future studies.

"Falls prevention among older people and care providers: protocol for an integrative review".

AIM: To review the evidence about the role of care providers in fall prevention in older adults aged ≥ 65 years, this includes their views, strategies, and approaches on falls prevention and effectiveness of nursing interventions. BACKGROUND: Some fall prevention programmes are successfully implemented and led by nurses and it is acknowledged the vital role they play in developing plans for fall prevention. Nevertheless, there has not been a systematic review of the literature that describes this role and care providers' views on fall's prevention initiatives. DESIGN: A convergent synthesis of qualitative, quantitative, and mixed methods studies. The eligibility criteria will be based on participants, interventions/exposure, comparisons, and outcomes for quantitative studies and on population, the phenomena of interest and the context, for qualitative studies. To extract data and assess study qualities members of the research team will work in pairs according to their expertise. The review will follow the guidelines for integrative reviews and the proposed methods will adhere to the PRISMA statement checklist complemented by the ENTREQ framework. As qualitative synthesis are emergent, all procedures and changes in procedure will be documented. DISCUSSION: The review has a constructivist drive as studies that combine methods ought to be paradigmatic driven. Review questions are broad to allow issues emerge and have purposefully left the design flexible to allow for adjustments as the review progresses. The review seeks to highlight the roles that care providers play in fall prevention and their views on fall's prevention initiatives.

Muscle mass loss measured with portable ultrasound in hospitalized older adults: The ECOSARC study.

OBJECTIVES: The main objective was to analyze the evolution of muscle of the Quadriceps Rectus Femoris (QRF) between admission and discharge, in older adults hospitalized with an acute medical disease in Acute Geriatric Units (AGUs). DESIGN: Prospective multicentric observational cohort study. SETTING: Seven AGUs from University Hospitals in Spain. PARTICIPANTS: Hospitalized adults ≥ 70 years old, able to ambulate and without severe dementia. MEASUREMENTS: Ultrasound measurements of QRF were acquired at 2/3 distal between anterior-superior iliac spine and patella in both legs by trained Geriatricians. Ultrasound Chison model ECO2 was used. QRF area, thickness, edema, echogenicity, and fasciculations were measured. RESULTS: From the complete sample (n = 143), in 45 (31.5%) participants, ultrasound images were classified as non-valid by an expert radiologist. Mean age was 87.8 (SD 5.4). Mean hospital stay 7.6 days (SD 4.3). From those with valid images, 36 (49.3%), 2 (2.7%), and 35 (47.9%) presented a decrease, equal values, or an increase in QRF area from baseline to discharge, respectively, and 37 (50.0%), 2 (2.7%), and 35 (47.3%) presented a decrease, equal values, or an increase in QRF thickness, respectively. 26 (35.6%) presented a decrease in more than 0.2 cm2 of QRF area, and 23 (31.1%) a decrease in more than 0.1 cm of QRF thickness. Only 4 (5.4%) patients presented new edema, while 13 (17.6%) worsened echogenicity. CONCLUSION: One third of older adults develop significant muscle loss during a hospitalization for acute medical diseases. TRIAL REGISTRATION NUMBER: NCT05113758.

Development of Continuous Assessment of Muscle Quality and Frailty in Older Patients Using Multiparametric Combinations of Ultrasound and Blood Biomarkers: Protocol for the ECOFRAIL Study.

BACKGROUND: Frailty resulting from the loss of muscle quality can potentially be delayed through early detection and physical exercise interventions. There is a demand for cost-effective tools for the objective evaluation of muscle quality, in both cross-sectional and longitudinal assessments. Literature suggests that quantitative analysis of ultrasound data captures morphometric, compositional, and microstructural muscle properties, while biological assays derived from blood samples are associated with functional information. OBJECTIVE: This study aims to assess multiparametric combinations of ultrasound and blood-based biomarkers to offer a cross-sectional evaluation of the patient frailty phenotype and to track changes in muscle quality associated with supervised exercise programs. METHODS: This prospective observational multicenter study will include patients aged 70 years and older who are capable of providing informed consent. We aim to recruit 100 patients from hospital environments and 100 from primary care facilities. Each patient will undergo at least two examinations (baseline and follow-up), totaling a minimum of 400 examinations. In hospital environments, 50 patients will be measured before/after a 16-week individualized and supervised exercise program, while another 50 patients will be followed up after the same period without intervention. Primary care patients will undergo a 1-year follow-up evaluation. The primary objective is to compare cross-sectional evaluations of physical performance, functional capacity, body composition, and derived scales of sarcopenia and frailty with biomarker combinations obtained from muscle ultrasound and blood-based assays. We will analyze ultrasound raw data obtained with a point-of-care device, along with a set of biomarkers previously associated with frailty, using quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay. Additionally, we will examine the sensitivity of these biomarkers to detect short-term muscle quality changes and functional improvement after a supervised exercise intervention compared with usual care. RESULTS: At the time of manuscript submission, the enrollment of volunteers is ongoing. Recruitment started on March 1, 2022, and ends on June 30, 2024. CONCLUSIONS: The outlined study protocol will integrate portable technologies, using quantitative muscle ultrasound and blood biomarkers, to facilitate an objective cross-sectional assessment of muscle quality in both hospital and primary care settings. The primary objective is to generate data that can be used to explore associations between biomarker combinations and the cross-sectional clinical assessment of frailty and sarcopenia. Additionally, the study aims to investigate musculoskeletal changes following multicomponent physical exercise programs. TRIAL REGISTRATION: ClinicalTrials.gov NCT05294757; https://clinicaltrials.gov/ct2/show/NCT05294757. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/50325.

Immunogenicity after 6 months of BNT162b2 vaccination in frail or disabled nursing home residents: The COVID-A Study.

BACKGROUND: There is incomplete information regarding evolution of antibody titers against SARS-CoV-2 after a two-dose strategy vaccination with BNT162b2 in older adults in long-term care facilities (LTCFs) with frailty, disability, or cognitive impairment. We aimed to determine IgG antibody titer loss in older adults in LTCFs. METHODS: This is a multicenter longitudinal cohort study including 127 residents (90 females and 37 males) with a mean age of 82.7 years (range 65-99) with different frailty and disability profiles in two LTCFs in Albacete, Spain. Residents received two doses of BNT162b2 as per label, and antibody levels were determined 1 and 6 months after the second dose. Age, sex, previous history of coronavirus disease 2019 (COVID-19), comorbidity (Charlson Index), performance in activities of daily living (Barthel Index), frailty (FRAIL instrument), and cognitive status were assessed. RESULTS: The mean antibody titers 1 and 6 months after the second vaccine dose were 32,145 AU/ml (SD 41,206) and 6182 AU/ml (SD 13,316), respectively. Across all participants, the median antibody titer loss measured 77.6% (interquartile range [IQR] 23.8%). Notably, the decline of titers in individuals with pre-vaccination COVID-19 infection was significantly lower than in those without a history of SARS-CoV-2 infection (72.2% vs. 85.3%; p < 0.001). The median titer decrease per follow-up day was 0.47% (IQR 0.14%) and only pre-vaccination COVID-19 was associated with lower rate of antibody decline at 6 months (hazard ratio 0.17; 95% confidence interval 0.07-0.41; p < 0.001). Frailty, disability, older age, cognitive impairment, or comorbidity were not associated with the extent of antibody loss. CONCLUSIONS: Older adults in LTCFs experience a rapid loss of antibodies over the first 6 months after the second dose of BNT162b2 vaccine. Only pre-vaccination COVID-19 is associated with a slower rate of antibody decrease. Our data support immunization with a third dose in this vulnerable, high-risk population.

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.

[Frailty prevalence in hospitalized older adults. A systematic review.] / Prevalencia de fragilidad en adultos mayores hospitalizados. Revisión sistemática.

BACKGROUND: Theres is uncertain evidence regarding the prevalence, measurement tools, outcomes, and efficacy of the interventions on frailty in hospitalized older adults. For this reason, we present the results of a systematic review about Frailty and Hospital, following the PRISMA methodology. METHODS: We found 2,050 articles published in PubMed. After an initial assessment of titles and abstracts, complete comprehensive text lecture, and meta-analysis review, we finally included in the systematic review 246 originals. RESULTS: The main result of the systematic review is that from the 246 articles, 179 described frailty prevalence in hospital older adults, with a pooled prevalence of 41.4% (95% CI 38.4% to 44.4%; range 4.7% to 92.5%). The most frequent type of studies were those observational prospectives 166 (67.5%), being the rest observtcional retrospectives or cross-sectional 64 (26.2%) or randomized clinical trials 15 (6.1%). The most frequent healthcare levels where the studies took place were the Hospital/Hospitalization in 125 (50.8%), Geriatric Department in 41 (16.7%), Surgical Units in 23 (9.3%), Cardiology Department in 18 (7.3%), Emergency Department in 15 (6.1%), and other in 24 (9.8%). The most frequent used measurement tolos were the Clinical Frailty Scale in 69 works (28%), the frailty phenotype in 41 (15.9%), the Frailty Index in 39 (15.9%) and the FRAIL scale in 27 (11.0%). In several papers, more than one instrument was used, and in many of them, scales and cut-off points were arbitrarely determined, producing a great results heterogeneity. CONCLUSIONS: The prevalence of frailty in hospitalized older adults is very high. It is necessary to improve frailty measure homogenity and to realize randomized clinical trials in this population.

OBJETIVO: Existe escasa evidencia sobre la prevalencia, herramientas de medición, resultados de salud y eficacia de las intervenciones sobre la fragilidad en adultos mayores en medio hospitalario. Por ello, presentamos los resultados de una revisión sistemática de la Fragilidad en adultos mayores en medio hospitalario, siguiendo la metodología de la declaración PRISMA. METODOS: Se encontraron 2.050 artículos en PubMed. Tras la valoración inicial de los títulos y resúmenes, lectura de texto completo y revisión de los meta-análisis, al final se incluyeron en la revisión sistemática 246 originales. RESULTADOS: El principal resultado fue que, de los 246 originales revisados, 179 describían la prevalencia de fragilidad en adultos mayores en el hospital, siendo el porcentaje combinado del 41,4% (IC 95% 38,4% a 44,4%; rango 4,7% a 92,5%). Por tipo de estudios predominaron los observacionales prospectivos 166 (67,5%), observacionales retrospectivos o transversales 64 (26,2%) y ensayos clínicos 15 (6,1%). Los dispositivos asistenciales más frecuentes fueron el Hospital en general/Hospitalización 125 (50,8%), Geriatría 41 (16,7%), Unidades quirúrgicas 23 (9,3%), Cardiología 18 (7,3%), Urgencias/emergencias 15 (6,1%) y otros dispositivos médicos 24 (9,8%). Las herramientas de valoración de la fragilidad más empleadas fueron la Clinical Frailty Scale en 69 artículos (28%), fenotipo de fragilidad en 41 (16,7%), Frailty Index en 39 (15,9%) y herramienta FRAIL en 27 (11,0%). En varios artículos se emplearon dos o más de las herramientas descritas, y en muchos, las escalas y los puntos de corte fueron arbitrariamente modificados por los autores, generando una gran heterogeneidad en los resultados. CONCLUSIONES: La prevalencia de fragilidad en adultos mayores en el hospital es muy alta, pero es necesaria una mayor uniformidad en su medición y la implementación de ensayos clínicos para evaluar intervenciones.

The Functional Continuum Scale in Relation to Hospitalization Density in Older Adults: The FRADEA Study.

BACKGROUND: There is a need to know the relationship between function and hospitalization risk in older adults. We aimed at investigating whether the Functional Continuum Scale (FCS), based on basic (BADL) and instrumental (IADL) activities of daily living and frailty, is associated with hospitalization density in older adults across 12 years of follow-up. METHODS: Cohort study, with a follow-up of 12 years. A total of 915 participants aged 70 years and older from the Frailty and Dependence in Albacete (FRADEA) study, a population-based study in Spain, were included. At baseline, the FCS, sociodemographic characteristics, comorbidity, number of medications, and place of residence were assessed. Associations with first hospitalization, number of hospitalizations, and 12-year density of hospitalizations were assessed using Kaplan-Meier curves, Poisson regression analyses, and density models. RESULTS: The median time until the first hospitalization was shorter toward the less functionally independent end of the FCS, from 3917 days (95% confidence interval [CI] 3701-3995) to 1056 days (95% CI 785-1645) (p < .001). The incidence rate ratio (IRR) for all hospitalizations increased from the robust category until the frail one (IRR 1.89), and thereafter it decreased until the worse functional category. Those who were BADL dependent presented an increased hospitalization density in the first 4 follow-up years (58%), those who were frail in the third-to-sixth follow-up years (55%), while in those prefrail or robust the hospitalization density was homogeneous during the complete follow-up. CONCLUSIONS: The FCS is useful for stratifying the risk of hospitalization and for predicting the density of hospitalizations in older adults.

JAK inhibition reduces SARS-CoV-2 liver infectivity and modulates inflammatory responses to reduce morbidity and mortality.

Using AI, we identified baricitinib as having antiviral and anticytokine efficacy. We now show a 71% (95% CI 0.15 to 0.58) mortality benefit in 83 patients with moderate-severe SARS-CoV-2 pneumonia with few drug-induced adverse events, including a large elderly cohort (median age, 81 years). An additional 48 cases with mild-moderate pneumonia recovered uneventfully. Using organotypic 3D cultures of primary human liver cells, we demonstrate that interferon-α2 increases ACE2 expression and SARS-CoV-2 infectivity in parenchymal cells by greater than fivefold. RNA-seq reveals gene response signatures associated with platelet activation, fully inhibited by baricitinib. Using viral load quantifications and superresolution microscopy, we found that baricitinib exerts activity rapidly through the inhibition of host proteins (numb-associated kinases), uniquely among antivirals. This reveals mechanistic actions of a Janus kinase-1/2 inhibitor targeting viral entry, replication, and the cytokine storm and is associated with beneficial outcomes including in severely ill elderly patients, data that incentivize further randomized controlled trials.

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.

[Nutritional status in older adults admitted to an acute geriatric unit]. / Estado nutricional de ancianos hospitalizados en una unidad geriátrica de agudos.

INTRODUCTION: Objective: to describe the nutritional status of older adults hospitalized in an acute geriatric unit (AGU) and its association with mortality and days of hospitalization. Material and methods: a retrospective study in 1,084 adults older than 65 years, hospitalized in an AGU. The Mini Nutritional Assessment®-Short Form (MNA®-SF) and subjective global assessment (SGA) were used. The association between nutritional status, mortality, and long hospital stay (> 7 days) was analyzed using regression models and Cox hazard models. Results: mean age was 86.5 years: 58.7% were women. Mean MNA®-SF score was 8.9 (20.0%, well nourished; 48.2%, at nutritional risk, and 31.7% with malnutrition). Using the SGA, 22.1% were well nourished, 54.7% had moderate malnutrition, and 23.2% had severe malnutrition. Agreement between SGA and MNA®-SF was good (kappa, 0.654; p < 0.001), and correctly classified 78.5% of participants. Malnutrition was associated with poorer cognitive status, greater disability, worse ambulation, and lower levels of total protein, albumin, cholesterol, and transferrin. Patients with malnutrition in the MNA®-SF assessment had a higher adjusted mortality risk than those who were well nourished (HR, 1.80; 95% CI, 1.01-3.20), same as those with SGA C versus A (HR, 1.66; 95% CI, 0.96-2.86). Patients with SGA B and C presented a higher adjusted risk of long hospitalization as compared to well nourished subjects (OR, 1.42; 95% CI, 1.04-1.96 and OR, 1.73; 95% CI, 1.18-2.54, respectively. Patients with malnutrition per the MNA-SF® presented a higher adjusted risk of long hospitalization as compared to well nourished subjects (OR, 1.59; 95% CI, 1.09-2.33). Conclusions: nutritional risk and malnutrition are very common in older adults in AGUs, and are associated with higher mortality and longer hospital stay.

INTRODUCCIÓN: Objetivo: describir el estado nutricional de los mayores hospitalizados en una unidad geriátrica de agudos (UGA) y su asociación con la mortalidad y la estancia hospitalaria. Material y métodos: estudio retrospectivo de 1084 personas mayores de 65 años en una UGA. Se emplearon el Mini Nutritional Assessment®-Short Form (MNA®-SF) y la valoración global subjetiva (VGS). La asociación entre estado nutricional, mortalidad y estancia hospitalaria prolongada (> 7 días) se analizó mediante un modelo de regresión y el análisis de riesgos de Cox. Resultados: edad media de 86,5 años: 58,7% de mujeres. La puntuación media del MNA®-SF fue de 8,9, estando el 20,0% sin riesgo nutricional, el 48,2% en riesgo nutricional y el 31,7% con malnutrición. Mediante la VGS, el 22,1% estaban bien nutridos, el 54,7% moderadamente desnutridos y el 23,2% gravemente desnutridos. El acuerdo entre VGS y MNA®-SF fue bueno (kappa = 0,654; p < 0,001), clasificando correctamente al 78,5% de los participantes. La malnutrición se asoció a peor estado cognitivo, mayor discapacidad, peor deambulación y niveles menores de proteínas totales, albúmina, colesterol y transferrina. Los pacientes con malnutrición según el MNA®-SF presentaron una mortalidad ajustada mayor que la de los bien nutridos (HR: 1,80; IC 95%: 1,01-3,20), igual que aquellos con VGS de C frente a los de A (HR: 1,66; IC 95%: 0,96-2,86). Los pacientes con VGS de B (OR: 1,42; IC 95%: 1,04-1,96) y C (OR: 1,73; IC 95%: 1,18-2,54) presentaron mayor riesgo ajustado de estancia hospitalaria prolongada frente a los bien nutridos. Los pacientes con malnutrición según el MNA®-SF presentaron mayor riesgo ajustado de estancia hospitalaria prolongada (OR: 1,59; IC 95%: 1,09-2,33) frente a los bien nutridos. Conclusiones: el riesgo nutricional y la malnutrición son muy frecuentes en los mayores hospitalizados en una UGA y se asocian con mayor mortalidad y estancias más prolongadas.

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.

Pilot study of a preventive multicomponent nurse intervention to reduce the incidence and severity of delirium in hospitalized older adults: MID-Nurse-P.

BACKGROUND: Although multicomponent interventions are the gold standard for delirium management, few nurse-led interventions in Acute Geriatric Units (AGU) are described. OBJECTIVES: To analyze if a preventive multicomponent non-pharmacologic nurse-led intervention randomized clinical trial (MID-Nurse Study) is feasible (pilot study), and can reduce the incidence, duration, and severity of delirium in hospitalized older adults in an AGU. DESIGN: Parallel-group double-blind randomized clinical trial (pilot Study). SETTING: AGU Complejo Hospitalario Universitario, Albacete (Spain). PARTICIPANTS: 50 patients ≥65 years hospitalized in the AGU. Intervention group (IG) 21, control group (CG) 29. INTERVENTION: After risk factor analysis, all participants in the IG received a daily multicomponent non-pharmacologic intervention (orientation, sensorial deficit, sleep, mobilization, hydration, nutrition, drug chart review, elimination, oxygenation, pain) by the intervention nurses. The CG received usual care. MEASUREMENTS: Daily delirium presence with the Confusion Assessment Method (CAM), and severity with the Delirium Rating Scale-Revised-98 (DRS). Outcome measures were delirium incidence, prevalence, severity, and number of days with delirium, mortality, length of stay, use of physical restraint measures, and use of drugs for delirium control. RESULTS: Mean age 86.5 (48% women). 21 participants presented delirium during hospitalization (14CG and 7 IG). Process, resources, management, and scientific objectives were considered positive, making the study feasible. Delirium prevalence (33.3% vs 48.3%) and incidence (14.3% vs 41.4%; p=0.039) were reduced in the IG compared to CG. Total delirium severity was lower in the IG compared to the CG (35.0 vs 65.0; p=0.040). Mortality was not different between groups (CG 17.2% vs IG 19.0%). CONCLUSION: The MID-Nurse Study is feasible, and a multicomponent nurse-led intervention on patients with delirium in an AGU can reduce delirium prevalence, incidence, and severity. The clinical trial registration number ClinicalTrials.gov ID: NCT02558777.
