Clinical profiles of older adults in French Caribbean nursing homes: a descriptive cross-sectional study.

Nursing homes in the Caribbean are scarce and the characteristics of their residents have not been previously documented. This study aimed to describe the clinical profiles of residents living in nursing homes in Guadeloupe and Martinique (French West Indies). This is a cross-sectional study of the baseline screening data from the KASEHPAD (Karukera Study of Ageing in nursing homes) study. Clinical characteristics and geriatric scale scores, including the Activities of Daily Living (ADL), Mini-Mental State Examination (MMSE), Mini Nutritional Assessment Short-Form (MNA-SF) and Short Physical Performance Battery (SPPB) were collected and analysed. A total of 332 older adults were recruited between September 2020 and November 2022. The mean age of the residents was 81.3 ± 10.1, with a male-female ratio of 1:1. Diabetes was reported in 28.3% of the residents, hypertension in 66.6% and heart disease in 18.4%. Dementia was diagnosed in 52.3% of the residents and 74.9% had a MMSE score ≤18. The prevalence of Parkinson's disease was 9.0%. Additionally, 18.4% were unable to perform any basic activities of daily living (ADL score of 0). The prevalence of physical impairment (SPPB < 8) was 90.0%. One-quarter of the residents were classified as undernourished (MNA-SF score ≤ 7). Residents in Caribbean nursing homes are younger than in metropolitan France, whereas they present quite similar clinical profiles. Notably, a high prevalence of diabetes, cardiovascular diseases and neurodegenerative diseases was observed. This study represents a preliminary effort to address the knowledge gap regarding the aging trajectories of older adults in the Caribbean and could guide the development of future nursing homes in these countries.

Effects of a multicomponent training and detraining on frailty status, physical activity level, sedentary behavior patterns and physical performance of pre-frail older adults: a randomized controlled trial.

To evaluate the effects of a multicomponent training protocol and detraining on frailty status, physical activity level, sedentary behavior patterns, and physical performance in pre-frail older adults. A randomized controlled blinded trial was conducted with pre-frail older adults (74.8 ± 6.4years, 70.4% female), who were allocated to receive a multicomponent training (MulTI = 16) or control group (CG = 11), which received guidance to maintain their daily living habits. Assessments of the frailty phenotype, physical activity levels measured by accelerometer, and physical performance (gait speed, timed up and go, short physical performance battery) were conducted at pre-intervention, post-intervention (16weeks), and follow-up (6weeks). The effect of the intervention was analyzed using the marginal homogeneity test and the two-way ANOVA with repeated measures. All older adults who received the MulTI reversed their frailty status to non-frail (p < 0.001), and after follow-up, 87.5% remained non-frail. In the CG, one older adult reversed their frailty status to non-frail and another became frail (p > 0.05), maintaining this status after the follow-up period. Furthermore, only the older adults in the MulTI showed an improvement in gait speed post-intervention, which was maintained through follow-up (p = 0.008). No changes were observed in the other variables. The MulTI was efficient to reverse the process of frailty and improving gait speed in pre-frail older adults. However, receiving only the MulTI was not sufficient to increase physical activity levels and reduce sedentary behavior patterns, necessitating the implementation of behavioral change strategies.

The Short Physical Performance Battery does not correlate with daily life gait quality and quantity in community-dwelling older adults with an increased fall risk

BackgroundBoth the Short Physical Performance Battery (SPPB) and daily life gait quality and quantity obtained from wearable sensors are used to measure functional status in older adults. It is generally assumed that they are interrelated and exchangeable, but this has not yet been established. Interchangeability of these measures would pave the way for remote monitoring of functional status. Research QuestionAre the SPPB and daily life gait quality and quantity measures correlated in community-dwelling older adults? MethodsThe SPPB and gait quality and quantity data of 229 community-dwelling adults of 65 years or older were collected. The SPPB is a combined score of the Three Stage Balance test, Four Meter Walk test, and Five Times Sit to Stand test and ranges from 0 to 12. Participants wore a tri-axial inertial sensor for one week to assess gait quality (e.g. gait stability and smoothness) and quantity (e.g. number of strides). Correlation coefficients between SPPB scores and gait quality and quantity measures were assessed using Spearman’s correlation. ResultsThe median age of the study population was 76.2 years (IQR 72.6–81.0), and 76 % were women (n=175). The median SPPB score was 10 (IQR 8–11). Spearman's correlation coefficients between the SPPB and gait quality and quantity measures were all below 0.3. SignificanceA possible explanation for the observed weak correlations is that the SPPB reflects one’s maximal capacity, while gait quality and quantity reflect the submaximal performance in daily life. The SPPB and gait quality and quantity seem therefore distinct constructs with complementary value, rather than interchangeable. A more comprehensive understanding of functional status might be achieved by combining the SPPB assessment of standardized activities with the evaluation of inertial sensor measurements obtained during daily life activities.

Feasibility of a Multidomain Resiliency Assessment in Patients with Advanced Heart Failure Requiring Surgery: A Pilot Study.

The resiliency of patients who have advanced heart failure (HF) and undergo a physical stressor such as heart transplantation or left ventricular assist device implantation has yet to be studied in the physical, cognitive, and psychosocial domains. The primary aim of this pilot study was to assess the feasibility of a multidomain resiliency assessment in patients who have advanced HF and require surgery. A battery of assessments in each of the domains was completed at baseline before surgical intervention, after intensive care discharge, and 3 and 6months after surgery. Feasibility was assessed through completion rates, time required to complete the assessments, and qualitative feedback from assessors. Although various completion rates were noted at different time points, high completion rates were seen for grip strength, the modified Fried frailty phenotype, and the Montreal Cognitive Assessment. Additionally, when controlled for patients who were medically restricted from physical function, the Short Physical Performance Battery, gait speed, and the 30-second chair stand test also had high completion rates. A trend toward return to baseline status or an improvement in baseline status was observed in all physical and cognitive assessments and most psychosocial assessments at 3 and 6months. Minimal change was noted in the Brief Resilience Scale questionnaire. This pilot study demonstrates that a multidomain assessment of resiliency is feasible in patients with advanced HF. Future studies are needed to help determine specific assessments or patient factors that would help predict positive postsurgical outcomes in this population. This study has implications for clinical practice on the most feasible assessments in multiple domains for patients who have advanced HF and are being evaluated for heart transplantation or left ventricular assist device.

Dietary protein intake and its association with physical fitness test among older adults with pre-sarcopenia and sarcopenia: A cross-sectional study.

Low protein intake and physical inactivity are factors that associated with muscle deterioration and poor physical performance among older adults. To assess the association between dietary protein intake and physical fitness tests among older adults with pre-sarcopenia and sarcopenia. A total of 110 older adults were recruited through a convenience sampling method. Data including sociodemography, anthropometry, body composition, medical history, and dietary protein intake were obtained through the interview-administered method. Most of the subjects have low household income (<RM 3030) (90%), Malay ethnicity (66.4%), and are married (64.5%). 74.55% of the subjects were pre-sarcopenic, whereas 25.45% were sarcopenic. Those with sarcopenia were mostly underweight (± 21.78 kg/m2), whereas those with pre-sarcopenia had a slightly higher Body Mass Index (BMI) (± 27.30 kg/m2). Both men and women did not meet the dietary protein requirement (± 43.86 g/ day) based on the Recommended Nutrient Intake (RNI) of 2017. Moreover, both pre-sarcopenic and sarcopenic subjects have reduced functional ability. Although no significant differences were found in the Short Physical Performance Battery (SPPB) score, those with sarcopenia had poorer physical performance than those with pre-sarcopenia (82.1% versus 69.5%). Apart from that, there was a significant association between the 2-min step test (2MST) and dietary protein intake among those with pre-sarcopenia (r-value = 0.252). In conclusion, lifestyle interventions among older adults are important, including ensuring adequate protein intake and encouraging appropriate physical activity to enhance muscle mass, strength, and performance to improve their daily life efficiency and quality of life.

Short physical performance battery in aerobic capacity and physical activity evaluation of individuals with peripheral artery disease: An exploratory study

BackgroundPeripheral artery disease (PAD) negatively affects functional ability. Persons with PAD experience gait limitation, and changes in mobility, muscle strength, and balance. Assessing individuals with PAD with tests of lower limb performance during activities other than walking may provide information about aerobic capacity. ObjectiveTo evaluate whether the Short Physical Performance Battery (SPPB) can discriminate aerobic capacity and level of physical activity in individuals with PAD. MethodsThe SPPB, Incremental Shuttle Walking Test (ISWT), and the Human Activity Profile (HAP) were completed by 42 volunteers with PAD. The sample was stratified into tertiles by the distance walked in the ISWT and the Adjusted Activity Score (AAS) of HAP. One-way analysis of variance with a post-hoc least significant difference was used to compare the SPPB values between tertiles of ISWT and AAS of HAP. P-value < 0.05 was considered significant. ResultsThe mean age was 65 ± 7.7 years, the walking distance was 259.29 ± 115.28 m, and AAS of HAP was 68.36 ± 9.04. There was a significant difference in the total SPPB score and scores for gait speed and sit-to-stand for groups stratified by ISWT and AAS of HAP(p = 0.01). The balance domain was different only for groups stratified into tertiles by AAS of HAP(p = 0.04). ConclusionThe results of this study have clinical relevance for the evaluation of individuals with PAD at different aerobic and physical activity levels. The SPPB is a viable alternative in the practice of the specialty of vascular nursing and other areas of health to assess patients whose ability to perform walking tests is often limited.

Evaluation of Five Screening Tools in Detecting Physical Frailty in Cirrhosis and Their Prognostic Role.

Background: Physical frailty (PF) is a syndrome of decreased physical function and reserves, preventing patients from coping with stressful events. PF screening tools in patients with liver cirrhosis (LC) can help evaluate the risk of complications and death. The aim of this study was to assess the performance of five screening tools in detecting PF and their ability to predict 18-month mortality in LC. Methods: The Short Physical Performance Battery (SPPB), Fried frailty phenotype (FFP), Clinical Frailty Scale (CFS) and 6-Minute Walk Test (6MWT) were compared with the Liver Frailty Index (LFI) as the method of reference. Patients with an LFI ≥ 4.5, SPPB ≤ 8, FFP ≥ 3, CFS ≥ 6 points, and those walking <250 m, were considered frail. Results: A total of 109 consecutive patients with stable LC were included [63.3% male, median age 62 years, (IQR 52-70), MELD 9 (7-14.5), 46.8% with decompensated LC (DC)]. PF was present in 23.9%, 27.5%, 41.3%, 13.8%, and 28.4% as assessed by the LFI, SPPB, FFP, CFS, and 6MWT, respectively. Cohen's kappa measurement of agreement of four of the tools with LFI was 0.568, 0.334, 0.439, and 0.502, respectively (p < 0.001 for each). Kaplan-Meier survival curves at 18 months showed higher mortality in frail patients compared to non-frail patients by any method (log rank p < 0.05). In the multivariate models, PF defined by any method emerged as an independent prognostic factor of 18-month mortality after adjustment for age, gender, and MELD-score. Conclusions: Patients characterized as frail by five screening tools were not identical. However, PF defined by either method was proven to be an independent poor prognostic factor for long-term mortality after adjustment for covariates.

Effects of High Dose Bolus Cholecalciferol on Free Vitamin D Metabolites, Bone Turnover Markers and Physical Function.

High dose bolus cholecalciferol supplementation has been associated with falls and fracture, and this does not appear to be due to hypercalcaemia. The primary aim of this study was to determine the change in free vitamin D and metabolites after high dose bolus supplementation. This was a single centre, double-blinded, randomised, controlled trial of three different oral bolus doses of vitamin D3 (50,000 IU, 150,000 IU, and 500,000 IU) in otherwise healthy, vitamin D deficient (total 25-hydroxylated vitamin 25(OH)D < 30 nmol/L) postmenopausal women. Thirty-three women were randomized to one of the three treatment groups. Twenty-seven vitamin D sufficient (25(OH)D > 50 nmol/L) postmenopausal women were recruited as a concurrent control group. Participants attended five study visits over three months. We measured total 25(OH)D3 and free 25(OH)D, total and free 1,25(OH)2D, parathyroid hormone, fibroblast-growth factor-23, serum calcium, ionised calcium, urinary calcium excretion, and bone turnover markers (procollagen I N-propeptide (PINP), serum C-telopeptides of type I collagen (CTX-I) and Osteocalcin (OC)). We assessed muscle strength and function with grip strength and a short physical performance battery. Postural blood pressure and aldosterone:renin ratio (ARR) was also measured. Total 25(OH)D3 and free 25(OH)D increased in response to dose, and there were proportionate increases in total and free metabolites. Treatment did not affect serum calcium, postural blood pressure, ARR, or physical function. Bone turnover markers increased transiently one week after administration of 500,000 IU. High dose bolus cholecalciferol supplementation does not cause disproportionate increases in free vitamin D or metabolites. We did not identify any effect on blood pressure regulation or physical function that would explain increased falls after high dose treatment. A transient increase in bone turnover markers one week after a 500,000 IU bolus suggests that very high doses can have acute effects on bone metabolism, but the clinical significance of this transient increase is uncertain.

Taiwanese reference values for the Short Physical Performance Battery in community-dwelling older adults

ObjectivesTo establish reference values for SPPB score as well as test performances among Taiwanese community-dwelling older adults. MethodsParticipants included 847 older adults. The total scores and three subtest scores for the SPPB and the registered time to complete the walk and five-repetition sit-to-stand (STS) tests were determined and compared between sex and age (65–74, 75–84, and ≥85 years) groups. ResultsThe mean SPPB total score was 10.9 in women and 10.5 in men. SPPB scores did not differ by sex, regardless of age group. However, the walk test (p = .030) and STS test (p = .008) timings were longer for men than for women in the 65–74-year-old group. The ≥85-year-old men achieved a lower balance score than did the 65–74-year-old men (p = .027). ConclusionsPopulation-specific SPPB reference values contribute to assessments of physical function and facilitate cross-cultural comparisons of physical performance.

Short-physical performance battery: complete mediator of cognitive depressive symptoms and diabetes mellitus in hemodialysis patients

ObjectiveThis study aimed to examine the relationship between different dimensions of depressive symptoms and the presence of diabetes mellitus in hemodialysis patients. Additionally, the study sought to elucidate the mediating effect of physical performance on this association.MethodsThis was a cross-sectional multicenter study conducted between July 2020 and March 2023, involving 1024 patients from eight hemodialysis centers in Shanghai. Diabetes mellitus was based on a documented physician diagnosis and blood glucose tests. Physical performance and depressive symptoms were assessed using short-physical performance battery (SPPB) and the patient health questionnaire-9, respectively. Regression and mediation analysis were applied to statistical analysis.ResultsAmong the 1024 participants, 39.26% (n = 402) were found to have coexisting diabetes mellitus. Diminished SPPB scores (OR = 0.843, 95% CI = 0.792–0.897) and cognitive depressive symptoms (OR = 1.068, 95% CI = 1.011–1.129) exhibited significant associations with diabetes mellitus, while somatic depressive symptoms did not show a significant correlation. Notably, SPPB emerged as a complete mediator in the relationship between cognitive depressive symptoms and diabetes mellitus. The observed indirect effect of SPPB on this relationship was estimated at 0.038 (95% CI: 0.021–0.057).ConclusionThis study showed an association between diabetes mellitus and cognitive depressive symptoms in patients undergoing hemodialysis, with physical performance appearing to mediate the relationship between diabetes mellitus and depressive symptoms.

Multidimensional frailty assessment: Development and validation of the Tilburg Frailty Indicator-Indonesia version

The aim of this study was to develop and examine the psychometric properties of the Tilburg Frailty Indicator-Indonesian version (TFI-I). 308 community-dwelling older adults aged ≥60 years participated. The TFI-I exhibited favorable internal consistency (Cronbach's alpha = 0.775) and test–retest reliability (intraclass correlation coefficient = 0.94). The physical, psychological, and social domains of the TFI-I correlated closely with the similar constructs of other scales, including the Short Physical Performance Battery (P < .001), Fried Frailty Phenotype (P < 0.001), Geriatric Depression Scale (P < .001), and the World Health Organization Quality of Life scale (P = 0.041), indicating its favorable construct validity. Significant differences were identified between the robust and frailty groups on the Barthel Index (P = .001) and Lawton Instrumental Activity of Daily Living Scale (P < .001). Overall, the TFI-I is valid and reliable when used to evaluate frailty status in clinical and research settings.

Safety and Effectiveness of Acceleration Training as Cardiac Rehabilitation Immediately After Open Heart Surgery - A Pilot Study.

We examined the safety and efficacy of acceleration training (AT) in patients immediately after cardiac surgery. This randomized controlled study included patients who underwent open-heart surgery using cardiopulmonary bypass. Of these patients, 31 received regular cardiac rehabilitation (CR) and 39 received AT in addition to regular CR (AT group). AT was provided using a vibration platform (Power Plate®Pro7TMand Power plate®personal; Performance Health System, Chicago, IL, USA). The AT group performed 5 static resistance training sessions: squats, wide stance squats, toe stands, banded squats, and front lunges. Each vibration session lasted 30 s. We evaluated the short physical performance battery, anterior mid-thigh thickness, maximum voluntary isometric contraction of the knee extensors, and serum intercellular adhesion molecule (ICAM-1) and vascular cell adhesion molecule (VCAM-1) concentrations as indicators of endothelial function. The observation period was during hospitalization and lasted approximately 20 days. No adverse events occurred during AT. Ultrasound revealed a significantly lower reduction in muscle mass at discharge in the AT group. No significant differences were observed in ICAM-1 and VCAM-1 concentrations between the 2 groups preoperatively, postoperatively, or at discharge. AT is considered safe and effective for patients immediately after open-heart surgery. AT, along with regular CR, may prevent skeletal muscle mass loss, muscle weakness, and physical function loss immediately after open-heart surgery.

Resiliency among older adults receiving lung cancer treatment (ROAR-LCT): A novel supportive care intervention for older adults with advanced lung cancer

IntroductionNovel supportive care interventions designed for an aging population with lung cancer are urgently needed. We aimed to determine the feasibility of a novel supportive care physical therapy (PT) plus progressive muscle relaxation (PMR) intervention delivered to older adults with advanced lung cancer in the United States (US). Materials and MethodsThis clinical trial, Resiliency Among Older Adults Receiving Lung Cancer Treatment (ROAR-LCT: NCT04229381), recruited adults aged ≥60 years with unresectable stage III/IV non-small cell (NSCLC) or small cell lung cancer (SCLC) receiving cancer treatment at The James Thoracic Oncology Center (planned enrollment, N = 20). There were no exclusion criteria pertaining to performance status, laboratory values, prior cancer diagnoses, comorbidities, or brain metastases. Participants were evaluated by PT and psychology and given an exercise pedaler, resistance bands, a relaxation voice recording, and instructions at study initiation. Participants were evaluated in-person by PTs and psychologists at the start and end of the 12-session intervention, with the intervening sessions conducted via virtual health. Participants completed self-reported measures of functional status, symptoms, and mood longitudinally with the following instruments: EQ-5D-5L, Patient Health Questionnaire-9, and General Anxiety Disorder-7. PT assessments included the Short Physical Performance Battery (SPPB) and the two-minute walk test. Feasibility was defined as at least 60% of participants completing at least 70% of all intervention sessions. Optional gut microbiome samples and activity monitoring data (ActiGraph®) were also collected. ResultsThe ROAR-LCT study concluded after consenting 22 patients. Among the 22 consented, 18 (81.8%) started the intervention; 11 participants (61.1%) completed at least 70% of all study sessions. All participants with SCLC completed the intervention. Reasons for withdrawal included progression of disease or hospitalization. The majority (88.9%) of patients who started were able to complete at least one virtual health session. Participants' functional status, SPPB, depression, and anxiety scores were stable from pre- to post-intervention. Participants who withdrew had worse baseline scores across domains. Seven microbiome and six ActiGraph® samples were collected. Discussion: This is one of the first PT + PMR supportive care interventions using virtual health among older adults with advanced lung cancer to achieve feasibility in the US.

Descriptive Study on the Relationship between Dyspnea, Physical Performance, and Functionality in Oncology Patients.

Cancer is a leading cause of morbidity and mortality globally. Dyspnea, affecting up to 60% of cancer patients, exacerbates physical and psychological distress, reducing quality of life. This study aims to explore the relationship between dyspnea and factors such as age, sex, clinical diagnosis, and treatment lines in cancer patients, with the goal of improving understanding and management of this debilitating symptom to enhance patient care and quality of life. This study employed an observational, cross-sectional, and descriptive approach to investigate patients with oncological disease at the University Hospital of Salamanca between March 2021 and April 2024. A convenience sample was selected, including patients over 18 years old with a pathological diagnosis of cancer, experiencing any degree of dyspnea, and who consented to participate by signing the informed consent. Exclusion criteria included lack of consent and clinical conditions that prevented an interview. The studied variables encompass sociodemographic (age, gender, diagnosis, tumor stage, number of treatment lines) and clinical aspects (daily activities, degree of dyspnea, functional capacity, physical performance), evaluated using the Barthel Index, the mMRC Dyspnea Scale, the ECOG Scale, and the Short Physical Performance Battery (SPPB). Data were collected through semistructured interviews and medical records, and analyzed using specialized software. This research has ethical approval CEiM Code 2023 12 1472, Reference 2024/01. The mean age was 66.82 years. Lung cancer was predominant (60.2%), with most patients in stage 3 (65.7%) and receiving three treatment lines (68.7%). Higher age, advanced disease stage, and more treatment lines correlated with lower Barthel and SPPB scores, and higher ECOG and mMRC scores, indicating worse functionality, physical performance, and greater dyspnea. No significant correlations were found between gender or pathological diagnosis and the studied variables. Advanced age, higher disease stage, and more treatment lines are associated with decreased functionality, poorer physical performance, and increased dyspnea in cancer patients. Gender and specific cancer diagnosis do not significantly affect these relationships. Addressing dyspnea is crucial to improving the quality of life and physical performance in this population. Future studies should explore additional factors like treatment types and nutritional status.

Prevalence and risk factors of osteosarcopenia in elderly patients with uncontrolled type 2 diabetes.

To assess the prevalence of osteosarcopenia (OS) in elderly patients with type 2 diabetes mellitus (T2DM) and explore the related risk factors for developing this condition. This cross-sectional study enrolled hospitalized T2DM patients aged 60 years and older. Patients underwent assessments of total hip bone mineral density (BMD), grip strength, the Short Physical Performance Battery (SPPB), and body composition. Based on the 2019 Asian Working Group for Sarcopenia (AWGS) criteria, appendicular skeletal muscle mass (ASM), grip strength, and SPPB were measured to diagnose sarcopenia. BMD and T values of the lumbar spine and hip were measured using dual-energy X-ray absorptiometry (DXA). Osteosarcopenia was defined when both sarcopenia and osteoporosis criteria were met. Statistical analysis included binary logistic regression to identify significant risk factors. A total of 254 hospitalized T2DM patients (80 males and 174 females) were included. They were divided into T2DM-OS (n = 58) and T2DM-NOS (n = 196) groups based on the presence of osteosarcopenia. The average ages were 72.724 ± 6.463 and 69.265 ± 6.035 years, respectively. The prevalence of osteosarcopenia in T2DM patients was 22.8%, with 20.7% (12 males) and 79.3% (46 females) in the T2DM-OS group. After adjusting for confounding factors, it was found that male gender (OR: 5.738, 95% CI: 1.602-20.551, P = 0.007), fasting plasma glucose (OR: 0.904, 95% CI: 0.821-0.995, P = 0.038), and ASMI (OR: 0.049, 95% CI: 0.013-0.184, P < 0.001) were major influencing factors for the development of osteosarcopenia in elderly T2DM patients. The prevalence of T2DM-OS is relatively high, with male gender, low fasting plasma glucose, and low ASMI identified as risk factors.

Metformin effects on plasma zonulin levels correlate with enhanced physical performance in osteoarthritis patients with diabetes.

Metformin (MTF) shows promise in protecting against physical decline in osteoarthritis (OA), but how it works remains unclear. We studied MTF's effects on gut permeability and its link to physical performance in OA patients. We studied four groups: control (n = 72), OA non-diabetic (n = 58), OA diabetic on MTF (n = 55), and OA diabetic on other anti-diabetics (n = 57). We measured zonulin levels, as intestinal permeability marker, hand-grip strength (HGS), Oxford knee scoring (OKS) to determine OA severity, and short performance physical battery (SPPB) to determine physical functions. Patients suffering from OA showed a reduction in HGS and SPPB scores with raised plasma zonulin than controls, irrespective of disease severity. MTF decreased plasma zonulin levels and improved OKS, gait speed, HGS, and SPPB scores in OA patients. However, OA patients taking other anti-diabetic medications demonstrated higher levels of plasma zonulin, reduced HGS, and SPPB scores. Furthermore, a robust correlation of plasma zonulin and HGS, OKS, gait speed, and SPPB scores in OA patients on MTF was observed. Moreover, we found reduced oxidative stress and inflammation associated with these alterations in OA patients treated with MTF. MTF improves HGS and physical performance by lowering zonulin levels, preserving gut permeability in OA patients.

Can Functional Motor Capacity Influence Mortality in Advanced Chronic Kidney Disease Patients?

Alterations in the body's nutritional status or composition may be observed as the kidney disease advances, which could influence the kidney's functional capacity and, consequently, could increase the risk of mortality. The aim of the study is to determine the influence of functional capacity on mortality assessed by different functional tests in patients with advanced chronic kidney disease (ACKD). A prospective observational study was designed, which included 225 patients followed for 8 years in a CKD clinic. The study assessed functional capacity by using a range of tests, which included the Short Physical Performance Battery, the 6 minutes walking gait test, the timed up and go, and the four versions of the sit-to-stand test. Additionally, body composition and nutritional conditions were considered, taking into consideration various biochemical indicators such as albumin, prealbumin, c-reactive protein (CRP), lymphocytes, and transferrin, muscle strength, comorbidity, and frailty. The relationship between functionality and all-cause mortality was investigated using a Cox proportional hazard model. A total of fifty patients died during the duration of the study. Patients who performed worse on the function and muscle strength tests showed a worse body composition and nutritional status, and exhibited a reduced life expectancy. Inflammation (CRP) was associated with an increased risk of mortality (model 1: hazard ratio (HR) = 1.246; 95% confidence interval (95% CI = 1.014-1.531; model 2: HR = 1.333; 95% CI = 1.104-1.610). Good functional capacity as determined by the SPPB test decreased the risk of mortality (model 1: HR = 0.764; 95% CI = 0.683-0.855; model 2 HR = 0.778; 95% CI = 0.695-0.872). Cut-off points of maximum sensitivity and specificity for mortality were obtained with different tests. The study demonstrated that functional capacity influences mortality in patients with ACKD, being higher in those patients with impaired functionality regardless of the test used, although the SPPB allows a larger number of patients to be assessed. Therefore, it is essential to incorporate the assessment of functionality into the comprehensive care of patients with CKD.

Comparison of two popular transducers to measure sit-to-stand power in older adults.

The Tendo Unit (TU) and GymAware (GA) are the two most frequently used linear transducers for assessing muscle power in older adults via the sit-to-stand (STS) test. Unlike TU, GA incorporates a sensor mechanism to correct for non-vertical movements, which may lead to systematic differences between devices. The aim of this study therefore was to compare GA to TU for measuring STS power in community-dwelling older adults. Community-dwelling adults (n = 51, aged ≥65 years, 61% female) completed a single chair stand, with peak power measured simultaneously using GA and TU. Participants also completed the pneumatic leg press, 8-Foot Up and Go (TUG) test, Short Physical Performance Battery (SPPB), and self-reported measures of physical function. Intraclass correlations (ICC) were used to assess agreement, and Pearson's correlations were used to assess correlations. The study protocol was prospectively registered on the Open Science Framework. In alignment with our pre-registered hypothesis, peak power demonstrated an ICC of 0.93 (95% CI: 0.88, 0.96). For secondary aims, both transducers showed a correlation greater than 0.8 compared to pneumatic leg press power. For physical performance outcomes, both TU and GA showed similar correlations, as hypothesized: SPPB (r = 0.29 for TU vs. 0.33 for GA), Chair Stands (r = -0.41 vs. -0.38), TUG Fast (r = -0.53 vs. -0.52), mobility questionnaire (r = 0.52 vs. 0.52) and physical function questionnaire (r = 0.44 vs. 0.43). GA and TU peak power showed a high degree of agreement and similar correlations with physical and self-reported performance measures, suggesting that both methods can be used for assessing STS power in older adults.

Malnutrition in Amyotrophic Lateral Sclerosis: Insights from Morphofunctional Assessment and Global Leadership Initiative on Malnutrition Criteria.

Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease frequently accompanied by malnutrition due to weight loss, increased energy expenditure, and muscle mass loss. This study aimed to evaluate morphofunctional assessment tools as predictors of malnutrition and to investigate their relationship with muscle status and disease severity in ALS patients. A cross-sectional study was conducted with 45 ALS patients at the San Cecilio University Hospital in Granada. Malnutrition was assessed using the Global Leadership Initiative on Malnutrition (GLIM) criteria. Morphofunctional assessment was performed using Bioimpedance Vectorial Analysis (BIVA), handgrip strength (HGS), and Short Physical Performance Battery (SPPB). Malnutrition prevalence was 38% according to GLIM criteria. Significant differences were observed between malnourished and non-malnourished groups in age (70 ± 9 vs. 62 ± 10 years, p = 0.01), sex (female prevalence: 58.8% vs. 25.0%, p = 0.02), dysphagia prevalence (83% vs. 29%, p < 0.001), PEG/PRG use (35.3% vs. 3.6%, p = 0.01), and ALSFRS-R scores (30 ± 12 vs. 34 ± 12, p = 0.02). Malnourished patients had lower values in anthropometric measurements, muscle mass obtained by BIVA, and phase angle (PA) (4.05 ± 0.8° vs. 5.09 ± 0.8°, p < 0.001). No significant differences were found in muscle strength or functional status. PA showed significant correlations with muscle strength (r = 0.52, p < 0.001) and muscle mass measures (r = 0.48, p < 0.001). Moreover, PA was associated with poorer disease progression and physical performance. In our sample, BIVA metrics such as PA (<4.3°), SPA (<-0.8), body cell mass (<9.2 kg/m), and extracellular water (>49.75%) were identified as malnutrition risk factors. The study underscores the critical importance of comprehensive morphofunctional assessment and the use of advanced diagnostic criteria, for early identification and intervention in malnutrition among people with ALS. Further research is warranted to validate these findings and develop targeted nutritional strategies into routine clinical practice.

Effects of a Multifactorial Program with Case Management for Falls Prevention on Functional Outcomes in Community-Dwelling Older People: A Randomized Clinical Study.

To evaluate the effects of a multifactorial fall prevention program based on CM on physical performance, the presence of pain, and the risk of falls and fractures in older people who have suffered falls. This randomized, single-blind clinical trial with parallel groups, Intervention Group (IG) and Control Group (CG), was composed of 55 older people with a history of falling, living in the community. All participants underwent an initial assessment via video call (containing anamnesis, timed up-and-go test, falls risk score, short physical performance battery, and clinical frax). The IG underwent CM, the physical exercise protocol, and the cognitive stimulation protocol. The CG was monitored through telephone calls and received general health and fall guidance. No significant results were found in the physical capacity, the presence of pain, the risk of falls, or the fractures between the Intervention and Control Groups and between assessments. This program was not effective in improving functional performance, but it was important for characterizing pain and the probability of fracture in the next 10 years in this population.
