The feasibility and reliability of measuring forearm muscle thickness by ultrasound in a geriatric inpatient setting: a cross-sectional pilot study.

BACKGROUND: Given the potential benefits of introducing ultrasound in the clinical assessment of muscle disorders, this study aimed to assess the feasibility and reliability of measuring forearm muscle thickness by ultrasound in a geriatric clinical setting. METHODS: Cross-sectional pilot study in 25 participants (12 patients aged ≥ 70 years in an acute geriatric ward and 13 healthy volunteers aged 25-50 years), assessed by three raters. Muscle thickness measurement was estimated as the distance between the subcutaneous adipose tissue-muscle interface and muscle-bone interface of the radius at 30% proximal of the distance between the styloid process and distal insertion of the biceps brachii muscle of the dominant forearm. Examinations were repeated three times by each rater and intra- and inter-rater reliability was calculated. Feasibility analysis included consideration of technological, economic, legal, operational, and scheduling (TELOS) components. RESULTS: Mean muscle-thickness measurement difference between groups was 4.4 mm (95% confidence interval [CI] 2.4 mm to 6.3 mm], p < 0.001). Intra-rater reliability of muscle-thickness assessment was excellent, with intraclass correlation coefficient (ICC) of 0.947 (95%CI 0.902 to 0.974), 0.969 (95%CI 0.942 to 0.985), and 0.950 (95%CI 0.907 to 0.975) for observer A, B, and C, respectively. Inter-rater comparison showed good agreement (ICC of 0.873 [95%CI 0.73 to 0.94]). Four of the 17 TELOS components considered led to specific recommendations to improve the procedure's feasibility in clinical practice. CONCLUSION: Our findings suggest that US is a feasible tool to assess the thickness of the forearm muscles with good inter-rater and excellent intra-rater reliability in a sample of hospitalized geriatric patients, making it a promising option for use in clinical practice.

Acute sarcopenia changes following hospitalization: influence of pre-admission care dependency level.

INTRODUCTION: Hospitalization is associated with acute changes in sarcopenia status in older people, but the influencing factors are not fully understood. Pre-admission care dependency level as a risk factor has not yet been investigated. OBJECTIVE: Evaluate if pre-admission care dependency level is an independent predictor of sarcopenia changes following hospitalization. SETTING AND SUBJECTS: Data came from the Sarcopenia 9+ EAMA Project, a European prospective multi-centre study. For this study, 227 hospitalised older people were included from four different hospitals in Belgium, Spain and Poland, between 18 February 2019 and 5 September 2020. METHODS: Sarcopenia status at admission and discharge were calculated using a combined score (desirability value) based on muscle mass (calf circumference), strength (grip) and function (walking speed). Ratio of admission to discharge status was the outcome (desirability ratio; 1.00 meaning no difference). Predictor variable was the pre-admission care dependency level, classified into three groups: independent older people living at home, dependent older people living at home and older people living in a care home. Linear regression models were applied, considering potential confounders. RESULTS: Mean desirability ratio for dependent older people living at home ('middle dependent group') was lower (0.89) compared to independent older people (0.98; regression coefficient -0.09 [95% CI -0.16, -0.02]) and care home patients (1.05; -0.16 [95% CI -0.01, -0.31]). Adjusting for potential confounders or using another statistical approach did not affect the main results. CONCLUSION: Dependent older people living at home were at higher risk of deterioration in sarcopenia status following hospitalization. In-depth studies investigating causes and potential interventions of these findings are needed.

Feasibility, tolerability, and effects of exercise-based prehabilitation after neoadjuvant therapy in esophagogastric cancer patients undergoing surgery: an interventional pilot study.

Patients requiring surgery for locally advanced esophagogastric cancer often require neoadjuvant therapy (NAT), which may have a detrimental impact on cardiorespiratory reserve. The aims of this study were to investigate the feasibility and tolerability of a 5-week preoperative high-intensity interval training program after NAT, and to assess the potential effects of the training protocol on exercise capacity, muscle function, and health-related quality of life (HRQL). We prospectively studied consecutive patients with resectable locally advanced esophageal and gastric cancer in whom NAT was planned (chemo- or chemoradiotherapy). Feasibility was assessed with the TELOS (Technological, Economics, Legal, Operational, and Scheduling) components, and data on exercise tolerability (attendance and occurrence of adverse or unexpected events). Exercise capacity was assessed with peak oxygen uptake (VO2peak) in a cardiopulmonary exercise test at baseline, post-NAT, and following completion of a high-intensity interval exercise training (25 sessions). Changes in muscle strength and HRQL were also assessed. Of 33 recruited subjects (mean age 65 years), 17 received chemoradiotherapy and 16 chemotherapy. All the TELOS components were addressed before starting the intervention; from a total of 17 questions considered as relevant for a successful implementation, seven required specific actions to prevent potential concerns. Patients attended a mean of 19.4 (6.4) exercise sessions. The predefined level of attendance (≥15 sessions of scheduled sessions) was achieved in 27 out of 33 (81.8%) patients. Workload progression was adequate in 24 patients (72.7%). No major adverse events occurred. VO2peak decreased significantly between baseline and post-NAT (19.3 vs. 15.5 mL/Kg/min, P < 0.05). Exercise led to a significant improvement of VO2peak (15.5 vs. 19.6 mL/kg/min, P < 0.05). Exercise training was associated with clinically relevant improvements in some domains of HRQL, with the social and role function increasing by 10.5 and 11.6 points, respectively, and appetite loss and fatigue declining by 16 and 10.5, respectively. We conclude that a structured exercise training intervention is feasible and safe following NAT in patients with esophagogastric cancer, and it has positive effects to restore exercise capacity to baseline levels within 5 weeks with some improvements in HRQL.

Defining sarcopenia: some caveats and challenges.

PURPOSE OF REVIEW: To summarize the latest advances and caveats in defining sarcopenia and discuss the implications of the most recent worldwide initiatives which are trying to harmonize the definition. RECENT FINDINGS: The evolution over time of the definitions of sarcopenia is discussed, with a focus on the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) definition and the Sarcopenia Definitions and Outcomes Consortium (SDOC) conference. The EWGSOP2 and the SDOC agree on the overall concept of sarcopenia, which involves both impaired function (low muscle strength) and structural damage (low muscle mass/quality). However, physical performance is considered as a diagnostic criterion (EWGSOP), a severity grading assessment (EWGSOP2) or an outcome (SDOC) pending on the definition used. Muscle strength has been recognized as the best predictor of health outcomes. Muscle mass alone, as part of the definition of cachexia, sarcopenia and malnutrition, is a nondefining parameter. Furthermore, there is a lack of precision in measurement techniques and variability of the cut-off points in defining it. SUMMARY: We discuss the relationship of sarcopenia with cachexia, malnutrition and frailty, and the areas that are hampering agreement. We summarize key scientific evidence, consider future study of this nutrition-related disease and raise concern about the need for a universal definition of sarcopenia.

Surgical Treatment of Residual Distal Intimal Flap during Eversion Carotid Endarterectomy.

BACKGROUND: Eversion carotid endarterectomy (ECEA) is an effective surgical technique for the treatment of internal carotid artery (ICA) stenosis. However, a residual distal intimal flap may determine a higher rate of neurological complications. The treatment of DIF may be challenging, and no definitive approach has been described. We describe a simple surgical option for the treatment of DIF. METHODS: After internal ECEA has been performed, stitches are positioned at the side of intimal flap. Suture sequence is performed from internal-external-external-internal artery wall including the everted ICA, maintaining the suture thread inside the vessel. Once the ICA is correctly repositioned, the suture thread is pulled out. Once the standard carotid anastomosis has been performed, the flap is finally tacked. RESULTS: Fifteen patients have undergone surgical repair of DIF with the modified technique. No patients developed neurological complications after the surgical procedure, and all patients are still alive at last follow-up visit. CONCLUSIONS: This simple technique seems a safe and feasible surgical option to correct DIF, avoiding challenging surgical procedures that may increase operative and clamping time.

Respiratory muscle strength training and neuromuscular electrical stimulation in subacute dysphagic stroke patients: a randomized controlled trial.

OBJECTIVE: To evaluate the effectiveness of inspiratory/expiratory muscle training (IEMT) and neuromuscular electrical stimulation (NMES) to improve dysphagia in stroke. DESIGN: Prospective, single-blind, randomized-controlled trial. SETTING: Tertiary public hospital. SUBJECTS: Sixty-two patients with dysphagia were randomly assigned to standard swallow therapy (SST) (Group I, controls, n=21), SST+ IEMT (Group II, n=21) or SST+ sham IEMT+ NMES (Group III, n=20). INTERVENTIONS: All patients followed a 3-week standard multidisciplinary rehabilitation program of SST and speech therapy. The SST+IEMT group's muscle training consisted of 5 sets/10 repetitions, twice-daily, 5 days/week. Group III's sham IEMT required no effort; NMES consisted of 40-minute sessions, 5 days/week, at 80Hz. MAIN OUTCOMES: Dysphagia severity, assessed by Penetration-Aspiration Scale, and respiratory muscle strength (maximal inspiratory and expiratory pressures) at the end of intervention and 3-month follow-up. RESULTS: Maximal respiratory pressures were most improved in Group II: treatment effect was 12.9 (95% confidence interval 4.5-21.2) and 19.3 (95% confidence interval 8.5-30.3) for maximal inspiratory and expiratory pressures, respectively. Swallowing security signs were improved in Groups II and III at the end of intervention. No differences in Penetration-Aspiration Scale or respiratory complications were detected between the 3 groups at 3-month follow-up. CONCLUSION: Adding IEMT to SST was an effective, feasible, and safe approach that improved respiratory muscle strength. Both IEMT and NMES were associated with improvement in pharyngeal swallowing security signs at the end of the intervention, but the effect did not persist at 3-month follow-up and no differences in respiratory complications were detected between treatment groups and controls.

Usefulness of citric cough test for screening of silent aspiration in subacute stroke patients: a prospective study.

OBJECTIVE: To detect silent aspiration in a homogeneous sample of stroke patients using the citric acid cough test. DESIGN: Prospective study. SETTING: Public university tertiary hospital. PARTICIPANTS: Consecutive subacute stroke patients (N=134; 74 men, 60 women; mean age ± SD, 62.2±11.9y; 11.7±9.9d after stroke) who had complained of dysphagic symptoms, referred for rehabilitation from December 2010 to October 2012. INTERVENTION: All patients were administered a citric acid cough test and underwent a videofluoroscopic swallowing study (VFSS). A reduced or an absent response on the citric acid cough test was considered when cough peaks were ≤4. A control group of healthy volunteers was also screened. MAIN OUTCOME MEASURES: The citric acid cough test results were compared with the VFSS results, which were used as a criterion standard. RESULTS: There were 36 patients with a positive citric acid cough test, of which the VFSS revealed penetration in 14 cases (38.9%), aspiration in 5 (13.9%), silent aspiration in 5 (13.9%), and normality in 12 patients (33.3%). The sensitivity and specificity indexes for the reliability of citric acid cough test as a screening method for silent aspiration in comparison with the VFSS were .19 and .71, respectively. Other comparisons were made between silent aspirators (Penetration Aspiration Scale=8) and different subgroups of patients, but values remained poor. CONCLUSIONS: The citric acid cough test using 1.0 (weight by volume)% for 1 minute does not seem to be a useful standalone tool to screen for silent aspiration in subacute stroke patients with suspected dysphagia.

Supplementation with ß-hydroxy-ß-methylbutyrate after resistance training in post-acute care patients with sarcopenia: A randomized, double-blind placebo-controlled trial.

OBJECTIVES: This study aimed to evaluate the efficacy of adding ß-hydroxy-ß- methylbutyrate (HMB) supplementation to a 12-week exercise-based rehabilitation program in older adults with sarcopenia after discharge from a post-acute geriatric rehabilitation unit. STUDY DESIGN: A randomized, double-blind, placebo-controlled trial with two parallel groups. The intervention group received 3 g/day of Ca-HMB and participated in a 12- week resistance training program (3 sessions/week). The control group received a placebo and followed the same training program. MAIN OUTCOME MEASURES: The primary outcomes were the improvements of handgrip strength and physical performance assessed through the Short Physical Performance Battery (SPPB) and 4-meter gait speed; and handgrip strength. All variables were assessed at baseline, post-intervention, and 1-year follow-up. RESULTS: After completing the 12-week exercise program, the intervention group showed significant improvements in SPPB-Balance (1.3, 95 %CI 0.3 to 2.4) and total SPPB score (2.2, 95 %CI 0.4 to 4.0). Intra-group analysis demonstrated gains in the SPPB-Chair Stand (0.7 points, 95 %CI 0.0 to 1.4) and total SPPB score (2.1 points, 95 %CI 0.3 to 3.9) in the intervention group. Improvements in handgrip strength were observed in women (3.7 kg, 95 %CI: 0.2 to 7.3) at the end of the intervention, and persisted at the 1-year follow-up. CONCLUSIONS: Our findings suggest that the supplementation of 3 g/day of Ca-HMB with resistance exercise may significantly enhance muscle strength and physical performance among older women with sarcopenia after recent hospitalization. Given this study's limitations, the intervention's effectiveness cannot be drawn, and further studies are needed.

Association between GLIM-defined malnutrition and hospitalizations in kidney transplant candidates: A post hoc analysis of a cohort study.

BACKGROUND: Malnutrition is frequent in patients with chronic kidney disease (CKD) and has a negative impact on morbidity, mortality, and quality of life. The objective of this study was to assess the value of the Global Leadership Initiative for Malnutrition (GLIM) criteria to predict hospitalizations and mortality in candidates to kidney transplant during their first year on the waiting list. METHODS: This was a post hoc analysis of 368 patients with advanced CKD. The main study variables were malnutrition, according to the GLIM criteria; number of hospital admissions during the first year on the waiting list; and mortality at the end of follow-up. Kaplan-Meier survival curves and binary logistic regression were performed, adjusting for age, frailty status, handgrip strength, and Charlson Index as potential confounders. RESULTS: The prevalence of malnutrition was 32.6%. Malnutrition was associated with increased risk of hospitalizations during the first year on the waiting list (odds ratio [OR] = 3.33 [95% CI = 1.34-8.26]), which persisted after adjustment for age and frailty status (adjusted OR = 3.61 [95% CI = 1.38-10.7]), age and handgrip strength (adjusted OR = 3.39 [95% CI = 1.3-8.85]), and age and Charlson Index (adjusted OR = 3.25 [95% CI = 1.29-8.13]). CONCLUSION: Malnutrition according to the GLIM criteria was highly prevalent in patients with CKD and was associated with a threefold increased risk of hospitalizations during the first year on the waiting list; these associations remained significant after adjusting for age, frailty status, handgrip strength, and comorbidities.

Association between Malnutrition Assessed by the Global Leadership Initiative on Malnutrition Criteria and Mortality in Older People: A Scoping Review.

The Global Leadership Initiative on Malnutrition (GLIM) criteria were introduced in 2018 for the diagnosis of malnutrition in adults. This review was aimed at gathering the evidence about the association between malnutrition according to the GLIM criteria and mortality in older people, an emerging and clinically meaningful topic in the implementation of the GLIM criteria in geriatric healthcare settings. This scoping review considered meta-analyses, systematic reviews, cohort studies, and cross-sectional studies published in PubMed, Scopus, and the Cochrane Database for Systematic Reviews from the development of the GLIM criteria in 2018 to January 2023. Seventeen articles (15 cohort and 2 cross-sectional studies) were included. The association between GLIM criteria and mortality had been assessed in hospitalized (11 over the 17 articles) and community-dwelling older populations, and those in nursing homes. The review found a strong association between malnutrition according to GLIM criteria and mortality in hospitalized (1.2-fold to 7-fold higher mortality) and community-dwelling older people (1.6-fold to 4-fold higher mortality). These findings highlight the prognostic value of the GLIM criteria and support strategies towards the implementation of malnutrition evaluation according to the GLIM, in order to optimize comprehensive geriatric assessment and provide older people with the highest quality of nutritional care. Studies in nursing home populations were very scarce and may be urgently required.

Evaluation of the Geriatric Nutritional Risk Index in predicting mortality in older patients with COVID-19 in the AgeBru cohort.

OBJECTIVE: To determine whether the Geriatric Nutritional Risk Index (GNRI) on hospital admission was associated to an increased 14-day and 12-month mortality-risk in older inpatients with COVID-19. METHODS: Cohort study of consecutive inpatients admitted with COVID-19 in a university hospital (20/03/2020-11/05/2021). INCLUSION CRITERIA: age over 65 years and positive polymerase chain reaction test. EXCLUSION CRITERIA: missing data for weight, height, and/or albumin, hospital-acquired COVID-19, or patients transferred to other health facilities. OUTCOME: all-cause mortality at 14-day and 12-month follow-up. GNRI [1.489 × albumin (g/L)] + [41.7 (weight/ideal body weight)] was assessed at admission; scores ≤98 indicated risk of malnutrition. Cox-proportional hazards models assessed the association between the admission GNRI and 14-day and 12-month mortality-risk, after adjusting by demographic and clinical variables, including inflammation (C-reactive protein). RESULTS: Of the 570 eligible patients, 224 (mean age 78 years; 52.2% women) met inclusion criteria and 151 (67.4%) were classified at risk of malnutrition. Twenty patients died during the 14-day and 42 during the 12-month follow-up. The risk of 14-day mortality was nearly 10 times higher in patients with GNRI scores ≤98 (HR = 9.6 [95%CI 1.3-71.6], P = 0.028); this association was marginally significant in the adjusted model (HR = 6.73 [95%CI 0.89-51.11], P = 0.065)]. No association between GNRI and the 12-month mortality-risk was found. CONCLUSIONS: The GNRI may play a role in the short-term prognosis of older inpatients with COVID-19. Further studies are required to confirm the short-term predictive validity of the GNRI within this population (Clinicaltrials.gov_NCT05276752).

New perspectives on frailty in light of the Global Leadership Initiative on Malnutrition, the Global Leadership Initiative on Sarcopenia, and the WHO's concept of intrinsic capacity: A narrative review.

This review gathered the evidence on the epidemiology of frailty, as well as on screening and diagnostic tools, and new perspectives, in light of the latest global frameworks in malnutrition, sarcopenia, and the World Health Organization's concept of intrinsic capacity. Frailty is a worldwide health challenge and highly prevalent in older adults and the population with chronic diseases independent of age. Regardless of the particular concept of frailty, many screening and diagnostic tools are able to identify frailty in older people, but none of them has shown superiority in every population and healthcare setting. Physical, cognitive, and social components are part of the larger context of frailty. The latest evidence-based initiatives on frailty recommend the use of validated tools to identify frailty's different components, tailored to the needs of specific populations and healthcare systems. Unintentional weight loss is a shared criterion between physical frailty and malnutrition according to the Global Leadership Initiative on Malnutrition criteria. A new definition of sarcopenia by the Global Leadership Initiative on Sarcopenia is awaited, but at present physical frailty shares with sarcopenia the criteria of low muscle function and physical performance (severity grading) according to the revised consensus of the European Working Group on Sarcopenia in Older People (EWGSOP2). The EWGSOP2 includes both muscle mass and function, with most scientific groups agreeing that function is a key hallmark of sarcopenia. The concept of intrinsic capacity features the reserves and positive aspects of aging, and responds to ageism by addressing the deficit model approach. Intrinsic capacity is an emerging, person-centered and public health indicator, aimed at preserving health at mid-life and beyond, to move towards a better aging process in the Decade of Healthy Aging 2020-2030.

Low Phase Angle Values Are Associated with Malnutrition according to the Global Leadership Initiative on Malnutrition Criteria in Kidney Transplant Candidates: Preliminary Assessment of Diagnostic Accuracy in the FRAILMar Study.

Malnutrition has a negative impact on patients with chronic diseases and its early identification is a priority. The primary objective of this diagnostic accuracy study was to assess the performance of the phase angle (PhA), a bioimpedance analysis (BIA)-derived parameter, for malnutrition screening using the Global Leadership Initiative for Malnutrition (GLIM) criteria as the reference standard in patients with advanced chronic kidney disease (CKD) waiting for kidney transplantation (KT); criteria associated with low PhA in this population were also analyzed. Sensitivity, specificity, accuracy, positive and negative likelihood ratios, predictive values, and area under the receiver operating characteristic curve were calculated for PhA (index test) and compared with GLIM criteria (reference standard). Of 63 patients (62.9 years old; 76.2% men), 22 (34.9%) had malnutrition. The PhA threshold with the highest accuracy was ≤4.85° (sensitivity 72.7%, specificity 65.9%, and positive and negative likelihood ratios 2.13 and 0.41, respectively). A PhA ≤ 4.85° was associated with a 3.5-fold higher malnutrition risk (OR = 3.53 (CI95% 1.0-12.1)). Considering the GLIM criteria as the reference standard, a PhA ≤ 4.85° showed only fair validity for detecting malnutrition, and thus cannot be recommended as a stand-alone screening tool in this population.

Intensive Rehabilitation Program in Older Adults with Stroke: Therapy Content and Feasibility-Preliminary Results from the BRAIN-CONNECTS Study.

The main objective was to assess the feasibility of an intensive rehabilitation program (IRP) for stroke patients; and secondly, to detect eventual age-related differences in content, duration, tolerability, and safety in a prospective observational cohort of patients diagnosed with subacute stroke, admitted to inpatient rehabilitation (BRAIN-CONNECTS project). Activities during physical, occupational and speech therapy, and time dedicated to each one were recorded. Forty-five subjects (63.0 years, 77.8% men) were included. The mean time of therapy was 173.8 (SD 31.5) minutes per day. The only age-related differences when comparing patients ≥65 and <65 years were a shorter time allocated for occupational therapy (-7.5 min (95% CI -12.5 to -2.6), p = 0.004) and a greater need of speech therapy (90% vs. 44%) in the older adults. Gait training, movement patterns of upper limbs, and lingual praxis were the most commonly performed activities. Regarding tolerability and safety, there were no losses to follow-up, and the attendance ratio was above 95%. No adverse events occurred during any session in all patients. Conclusion: IRP is a feasible intervention in patients with subacute stroke, regardless of age, and there are no relevant differences on content or duration of therapy.

Effects of Exercise Training on Circulating Biomarkers of Endothelial Function in Pulmonary Arterial Hypertension.

INTRODUCTION: In stable patients with pulmonary arterial hypertension (PAH), pulmonary rehabilitation (PR) is an effective, safe and cost-effective non-pharmacological treatment. However, the effects of PR on vascular function have been poorly explored. This study aimed to compare the amounts of circulating progenitor cells (PCs) and endothelial microvesicles (EMVs) in patients with PAH before and after 8 weeks of endurance exercise training as markers of vascular competence. METHODS: A prospective study of 10 consecutive patients with PAH that successfully finished a PR program (8 weeks) was carried out before and after this intervention. Levels of circulating PCs defined as CD34+CD45low progenitor cells and levels of EMVs (CD31+ CD42b-) were measured by flow cytometry. The ratio of PCs to EMVs was taken as a measure of the balance between endothelial damage and repair capacity. RESULTS: All patients showed training-induced increases in endurance time (mean change 287 s). After PR, the number of PCs (CD34+CD45low/total lymphocytes) was increased (p < 0.05). In contrast, after training, the level of EMVs (CD31+ CD42b-/total EMVs) was reduced. The ratio of PCs to EMVs was significantly higher after training (p < 0.05). CONCLUSION: Our study shows, for the first time, that endurance exercise training in patients with stable PAH has a positive effect, promoting potential mechanisms of damage/repair in favor of repair. This effect could contribute to a positive hemodynamic and clinical response.

The effect of motor relearning on balance, mobility and performance of activities of daily living among post-stroke patients: Study protocol for a randomised controlled trial.

Background: Balance and gait impairments are the most common motor deficits due to stroke, limiting the patients' daily life activities and participation in society. Studies investigating effect of task-specific training using biomechanical balance and gait variables (i.e. kinetic and kinematic parameters) as well as posturography after stroke are scarce. Objectives: The primary aim of this study is to assess the efficacy and long-term outcome of task-specific training based on motor relearning program (MRP) on balance, mobility and performance of activities of daily living among post-stroke patients. Methods: In this two-armed randomised controlled clinical trial, a total of 66 sub-acute stroke patients who meet the trial criteria will be recruited. The patients will randomly receive task-specific training based on MRP or a conventional physical therapy program (CPT). Twenty-four physiotherapy sessions will be conducted, divided into three training sessions per week, 1 h per session, for 8 weeks, followed by an analysis of changes in patient's balance, gait and performance of activates of daily living at three time periods; baseline, post-intervention and follow-up after 3-months, using clinical outcome measures and instrumental analysis of balance and gait. Discussion: The results of this study can guide to better understanding and provide an objective clinical basis for the use of task-specific training in stroke rehabilitation. Also, it intends to help bridge the current knowledge gap in rehabilitation and training recommendations to provide a therapeutic plan in post-stroke rehabilitation. Trial registration: ClinicalTrials.gov (NCT05076383). Registered on 13 October 2021 (Protocol version: v2.0).

Prognostic Utility of a New Risk Stratification Protocol for Secondary Prevention in Patients Attending Cardiac Rehabilitation.

Several risk scores have been used to predict risk after an acute coronary syndrome (ACS), but none of these risk scores include functional class. The aim was to assess the predictive value of risk stratification (RS), including functional class, and how cardiac rehabilitation (CR) changed RS. Two hundred and thirty-eight patients with ACS from an ambispective observational registry were stratified as low (L) and no-low (NL) risk and classified according to exercise compliance; low risk and exercise (L-E), low risk and control (no exercise) (L-C), no-low risk and exercise (NL-E), and no-low risk and control (NL-C). The primary endpoint was cardiac rehospitalization. Multivariable analysis was performed to identify variables independently associated with the primary endpoint. The L group included 56.7% of patients. The primary endpoint was higher in the NL group (18.4% vs. 4.4%, p < 0.001). After adjustment for age, sex, diabetes, and exercise in multivariable analysis, HR (95% CI) was 3.83 (1.51−9.68) for cardiac rehospitalization. For RS and exercise, the prognosis varied: the L-E group had a cardiac rehospitalization rate of 2.5% compared to 26.1% in the NL-C group (p < 0.001). Completing exercise training was associated with reclassification to low-risk, associated with a better outcome. This easy-to-calculate risk score offers robust prognostic information. No-exercise groups were independently associated with the worst outcomes. Exercise-based CR program changed RS, improving classification and prognosis.

Frailty in kidney transplant candidates: a comparison between physical frailty phenotype and FRAIL scales.

BACKGROUND: Frailty is common among advanced chronic kidney disease (CKD) patients who are kidney transplant (KT) candidates, and predisposes to poor outcomes after transplantation. However, frailty is not routinely measured during pretransplant work-up and it is unknown which metric should be used in this specific population. Our aim was to establish frailty prevalence in KT candidates according to different frailty scales. METHODS: Prospective longitudinal study of 451 KT candidates evaluated for frailty by both Physical Frailty Phenotype (PFP) and FRAIL scale at the time of inclusion on the KT waiting list. Clinical and functional characteristics including sociodemographics, comorbidities, disability and nutritional status were recorded. Agreement between PFP and FRAIL scales as well as dissonant patients were analyzed. RESULTS: Mean age was 60.9 years and 31.7% were female. Comorbidity burden among patients was high, with 36.9% and 16.2% presenting with diabetes and ischemic coronary disease, respectively. Disabilities were also frequent. More than 70% of patients presented with ≥ 1 PFP criteria while this percentage for ≥ 1 FRAIL criteria was 45.4%. Agreement between PFP and FRAIL was not good (kappa index 0.317). There were 132 patients who were pre-frail or frail according to PFP but non-frail according to the FRAIL scale and they presented with fewer comorbidities and less disability. CONCLUSIONS: Frailty is frequent in advanced CKD patients, although its prevalence may vary according to different scales. Agreement between PFP and FRAIL scale is not good, and FRAIL scale might misclassify as robust patients those frail/prefrail patients who are in better health conditions.

Frailty among chronic kidney disease patients on the kidney transplant waiting list: the sex-frailty paradox.

BACKGROUND: Frailty is defined as decreased physiologic reserve and resistance to stressors that predisposes patients towards poor health results. Its prevalence in chronic kidney disease (CKD) patients who are kidney transplant (KT) candidates is high. Frailty is associated with a higher rate of complications and mortality after transplant. It is unknown whether frailty phenotype differs depending on sex in this population. METHODS: This was a prospective longitudinal study of 455 KT candidates evaluated for frailty by physical frailty phenotype at the time of inclusion on the KT waiting list. Pre-frailty was defined as the presence of two criteria and frailty as three or more criteria. Univariate and multivariate analyses searched for associations of frailty status, frailty components and gender differences. RESULTS: Thirty percent of the total cohort resulted to be pre-frail (20%) or frail (10.3%), but disparities were observed between sexes, with 22.5% of men and 47.2% of women falling into one of these categories. Among frailty criteria, women presented with a higher percentage of exhaustion (39.6% versus 17%) and slowness (22.2% versus 9.6%) compared with men. Comorbidity burden was higher among frail men, whereas social factors were poorer between frail women. Disability was common among those patients who were frail, both men and women. CONCLUSIONS: Frailty is twice as frequent in advanced CKD women as men. Frailty criteria distribution and phenotype seem to differ among sexes, which might have implications in terms of specific and individualized interventions to improve their status before transplantation.
