Effects of a nurse-led motor function rehabilitation training program for patients with ischemic stroke and family caregivers: study protocol for a randomized controlled trial.

BACKGROUND: Both individuals and society bear a considerable burden from ischemic stroke (IS), not only do patients continue suffering from motor dysfunction after discharge from hospital, but their caregivers also undertake the principal responsibility of assisting them in reintegrating into the family and society. To better improve the IS patients' limb function and daily life activities, their caregivers should also be involved in the training of the motor function rehabilitation during the period transitioning from hospital back home. This study mainly aims to investigate the effects of a nurse-led training for IS patients and their family caregivers on the improvement of the patients' physical function and the burden of caregivers. METHODS/DESIGN: A randomized controlled trial with blind assessment will be conducted in hospitals and during the follow-ups at home. Fifty-eight pairs of adults diagnosed with ischemic stroke and their primary caregivers will be included. Participants will be randomly given with (1) a nurse-led, home-based motor rehabilitation training participated by caregivers (intervention group) or (2) routine self-care (control group). Both groups will receive assessment and health guidance on the day of discharge, and the intervention group will receive an additional home-based training program and supervision. These two groups will be followed up every week after discharge. The primary results are drawn from the evaluation of physical function and caregiver-related burden, and the secondary results derived from statistics of the modified Barthel index, stroke-specific quality of life, and National Institutes of Health Stroke Scale. Differences between the two groups will be measured by two-way repeated measures ANOVA, considering the data at baseline and at 1-week and 4-week follow-up after training. DISCUSSION: Results may provide novel and valuable information on the effects of this culturally appropriate, caregiver-involved, and home-based rehabilitation training on the physical function of IS patients and caregiver-related burden.

Investigating the trajectory of functional disability in systemic sclerosis: group-based trajectory modelling of the Health Assessment Questionnaire-Disability Index.

OBJECTIVES: To identify the trajectories and clinical associations of functional disability in systemic sclerosis (SSc). METHODS: Australian Scleroderma Cohort Study (ASCS) participants meeting ACR/EULAR criteria for SSc recruited within 5 years of disease onset, with ≥2 Health Assessment Questionnaire-Disability Index (HAQ-DI) scores were included. Group based trajectory modelling (GBTM) was used to identify the number and shape of HAQ-DI trajectories. Between group comparisons were made using the chi-squared test, two-sample t-test or Wilcoxon rank-sum test as appropriate. Multiple logistic regression was used to identify features associated with trajectory group membership. Survival analyses were performed using Kaplan Meier and Cox proportional hazard modelling. RESULTS: We identified two HAQ-DI trajectory groups within 426 ASCS participants with incident SSc: low-stable disability (n=221, 52%), and high-increasing disability (n=205, 48%). Participants with high-increasing disability were older at disease onset, more likely to have diffuse SSc (dcSSc), cardiopulmonary disease, multimorbidity, digital ulcers, and gastrointestinal involvement (all p≤0.01), as was use of immunosuppression (p<0.01). Multimorbidity was associated with high-increasing trajectory group membership (OR3.1, 95%CI1.1-8.8, p=0.04); independently, multiple SSc features were also strongly associated including dcSSc (OR2.3, 95%CI1.3-4.2, p<0.01), proximal weakness (OR7.3, 95%CI2.0-27.1, p<0.01) and joint contractures (OR2.7, 95%CI1.3-5.3, p<0.01). High-increasing physical disability was associated with an almost two-fold increased risk of mortality (HR1.9, 95%CI1.0-3.8, p=0.05), and higher symptom burden. CONCLUSIONS: Two trajectories of functional disability in SSc were identified. Those with high-increasing functional disability had a distinct clinical phenotype and worse survival compared to those with low-stable functional disability. These data highlight the pervasive nature of physical disability in SSc, and its prognostic importance.

Safety of Antiplatelet Therapy in Noncardioembolic Ischemic Stroke With Thrombocytopenia: The CASE II Study.

BACKGROUND: There is scant evidence regarding the safety of antiplatelet therapy in acute ischemic stroke (AIS) patients with thrombocytopenia. Our study aims to address this concern by examining AIS patients with thrombocytopenia from a large database in real-world settings. METHODS AND RESULTS: We included patients with AIS with a platelet count <100×109/L who had complete records of antiplatelet drug use. Those requiring anticoagulation or having contraindications to antiplatelet therapy were excluded. Short-term safety outcomes were in-hospital bleeding events, while the long-term safety outcome was 1-year all-cause mortality. A good clinical outcome was defined as functional independence, indicated by a modified Rankin Scale score of 0 to 2 at discharge. Propensity score matched analyses were used. We screened 169 423 patients with AIS from 90 stroke centers in the CASE II register, ultimately enrolling 2808 noncardioembolic patients with thrombocytopenia. In the propensity score matched analyses, no significant difference was observed between the antiplatelet and nonantiplatelet groups in terms of intracranial hemorrhage (odds ratio=0.855 [95% CI, 0.284-5.478]; P=0.160) or gastrointestinal bleeding (odds ratio=2.034 [95% CI, 0.755-5.478]; P=0.160). Antiplatelet therapy was associated with improved functional outcomes at discharge (odds ratio=1.405 [95% CI, 1.028-1.920]; P=0.033), and showed a trend towards reducing 1-year mortality (odds ratio=0.395 [95% CI, 0.152-1.031]; P=0.058). CONCLUSIONS: The use of antiplatelet therapy lessened as platelet count decreased in patients with AIS with thrombocytopenia. However, our findings suggest that antiplatelet medications remain safe and effective for this population.

Systematic Druggable Genome-Wide Mendelian Randomization Identifies Therapeutic Targets for Functional Outcome After Ischemic Stroke.

BACKGROUND: Stroke is a leading cause of death worldwide, with a lack of effective treatments for improving the prognosis. The aim of the present study was to identify novel therapeutic targets for functional outcome after ischemic stroke . METHODS AND RESULTS: Cis-expression quantitative trait loci data for druggable genes were used as instrumental variables. The primary outcome was the modified Rankin Scale score at 3 months after ischemic stroke, evaluated as a dichotomous variable (3-6 versus 0-2) and also as an ordinal variable. Drug target Mendelian randomization, Steiger filtering analysis, and colocalization analysis were performed. Additionally, phenome-wide Mendelian randomization analysis was performed to identify the safety of the drug target genes at the genetic level. Among >2600 druggable genes, genetically predicted expression of 16 genes (ABCC2, ATRAID, BLK, CD93, CHST13, NR1H3, NRBP1, PI3, RIPK4, SEMG1, SLC22A4, SLC22A5, SLCO3A1, TEK, TLR4, and WNT10B) demonstrated the causal associations with ordinal modified Rankin Scale (P<1.892×10-5) or poor functional outcome (modified Rankin Scale 3-6 versus 0-2, P<1.893×10-5). Steiger filtering analysis suggested potential directional stability (P<0.05). Colocalization analysis provided further support for the associations between genetically predicted expression of ABCC2, NRBP1, PI3, and SEMG1 with functional outcome after ischemic stroke. Furthermore, phenome-wide Mendelian randomization revealed additional beneficial indications and few potential safety concerns of therapeutics targeting ABCC2, NRBP1, PI3, and SEMG1, but the robustness of these results was limited by low power. CONCLUSIONS: The present study revealed 4 candidate therapeutic targets for improving functional outcome after ischemic stroke, while the underlying mechanisms need further investigation.

Predicting Complete versus Incomplete Long-Term Functional Independence after Acute AIS Grade D Spinal Cord Injury: A Prospective Cohort Study.

Background: The proportion of patients with American Spinal Injury Association Impairment Scale (AIS) grade D traumatic spinal cord injuries (tSCI) is increasing. Although initial motor deficits can be relatively mild, some individuals fail to recover functional independence. Objectives: This study aims to identify factors associated with failure to reach complete functional independence after AIS grade D tSCI. Methods: An observational prospective cohort study was conducted at a level 1 trauma center specialized in SCI care. A prospective cohort of 121 individuals with an AIS-D tSCI was considered. The baseline characteristics, length of acute stay, need for inpatient rehabilitation, and 12-month functional status were assessed. Univariate and classification and regression tree (CART) analyses were performed to identify factors associated with reaching complete versus incomplete functional independence (defined as perfect total SCIM III score at 12-month follow-up). Results: There were 69.3%, 83.3%, and 61.4% individuals reaching complete independence in self-care, respiration/sphincter management, and mobility, respectively. A total of 64 individuals (52%) reached complete functional independence in all three domains. In the CART analysis, we found that patients are more likely to achieve complete functional independence when they have a baseline motor score ≥83 (65% individuals) and if they present fewer medical comorbidities (70% individuals if Charlson Comorbidity Index [CCI] ≤4). Conclusion: About half of individuals with AIS grade D tSCI can expect complete long-term functional independence. It is important to recognize early during acute care individuals with baseline motor score <83 or a high burden of comorbidities (CCI ≥5) to optimize their rehabilitation plan.

Association between days spent at home and functional status and health among persons living with dementia.

BACKGROUND: Many persons living with dementias (PLWD) prefer to remain at home as long as possible, and days spent at home (DAH)-defined as the time an individual spends outside of healthcare facilities-has emerged as a person-centred outcome measure in this population. We examined the association between DAH and functional status and health among PLWD. METHODS: Utilizing a nationally representative cohort of individuals age 65 and older in the United States with dementia from the 2010-2018 Health and Retirement Study (HRS), we assessed the relationship between an ordinal categorical DAH variable and number of activities of daily living (ADLs) (range 0-10; 10 being independent), mobility (0-5; 5 being mobile), and self-rated health (SRH) (0-4; 4 being excellent), controlling for patient characteristics. DAH was defined as the number of self-reported days spent outside a hospital or nursing home in the time between survey waves, typically 730 days. RESULTS: We identified 3002 participants (4192 observations, average 1.4 observations per participant). The mean DAH was 704.4 days (SD 10.8 days) and 64.9% spent all days at home (i.e. 730 days). A 2-week decrease in DAH was associated with a lower ADL score by 0.32 points (95% confidence internal [CI]: 0.24-0.40, P-for-trend<0.001), a lower mobility score by 0.18 points (95% CI: 0.13-0.22, P-for-trend<0.001), and a lower SRH by 0.05 points (95% CI: 0.02-0.08, P-for-trend<0.001). CONCLUSION: We demonstrate that DAH is positively associated with important patient-reported outcomes among the dementia population, strengthening the argument for considering DAH as a meaningful outcome measure for PLWD.

Relationship between NT-proBNP, echocardiographic abnormalities and functional status in patients with subclinical siabetic cardiomyopathy.

INTRODUCTION: Persons with diabetes are at risk for developing a cardiomyopathy through several pathophysiological mechanisms independent of traditional risk factors for heart failure. Among those with diabetic cardiomyopathy (DbCM), the relationship between natriuretic peptides, cardiac structural abnormalities and functional capacity is largely unknown. METHODS: In this prespecified subgroup analysis of the Aldose Reductase Inhibition for Stabilization of Exercise Capacity in Heart Failure (ARISE-HF) trial, 685 participants with asymptomatic DbCM underwent baseline echocardiography data, laboratory investigations, and functional assessments. Participants were stratified by N-terminal pro-B type natriuretic peptide (NT-proBNP) quartiles, and correlation with echocardiographic and functional parameters were assessed using Spearman correlation test. RESULTS: The median NT-proBNP was 71 (Q1, Q3: 33, 135) ng/L. No association was observed between NT-proBNP concentrations and echocardiographic parameters of either diastolic or systolic dysfunction including global longitudinal strain, left ventricular ejection fraction, left ventricular mass index, left atrial volume index, E/E', or right ventricular systolic pressure. In contrast, NT-proBNP was significantly correlated with overall Kansas City Cardiomyopathy Questionnaire score (rho = - 0.10; p = 0.007), the Physical Activity Scale in the Elderly (rho = - 0.12; p = 0.004), duration of cardiopulmonary exercise testing (rho = - 0.28; p < 0.001), peak VO2 (rho = - 0.26; p < 0.001), and ratio of minute ventilation/carbon dioxide production (rho = 0.12; p = 0.002). After adjustment for known confounders, the correlation with Physical Activity Scale in the Elderly and overall Kansas City Cardiomyopathy Questionnaire score was no longer significant. CONCLUSION: Among patients with subclinical DbCM, elevated NT-proBNP concentrations are associated with worse health status, lower activity levels, and reduced functional capacity, but not with cardiac structural abnormalities. These findings suggest that regardless of cardiac structural abnormalities, biomarker concentrations reflect important deterioration in functional capacity in affected individuals.

Malnutrition contribution to the functional status and health related quality of life after COVID-19, a correlational follow-up study.

To assess malnutrition contribution to the functional status and health related quality of life after hospitalization due to COVID-19 pneumonia, 66 selected adults referred for physical rehabilitation accepted to participate in the study; none of them required oxygen supply or had history of lung/musculoskeletal/neurological/immune/rheumatic disease or trauma, or contraindication for respiratory-function tests. At three evaluations, with 3 months in-between, assessments included: self-report of functional status, the St. George's Respiratory Questionnaire, spirometry, the 6-min-walk-test, the MRC-scale, the 30-s sit-to-stand-test, the timed-up-and-go-test, nutritional status, and ultrasound imaging (vastus medialis and diaphragm). At referral, patients had nutritional deficits with protein deficiency, which gradually improved; while muscle thickness (of both vastus medialis and diaphragm) increased, along with muscle strength and mobility (ANOVA, p < 0.05). Contrarywise, the distance covered during the 6-min-walk-test decreased (ANOVA, p < 0.05), with a negative influence from excess body mass. During rehabilitation, health-related quality of life and functional status improved, with negative influence from a history of tobacco use and referral delay, respectively. After hospitalization due to COVID-19, early diagnosis of both protein deficiency and decrease of skeletal muscle thickness could be relevant for rehabilitation, while pondering the negative impact of excess body mass on submaximal exercise performance.

Beyond pain: the influence of psychological factors on functional status in fibromyalgia.

OBJECTIVES: Fibromyalgia (FM) is characterised by chronic widespread pain, often associated with fatigue, sleep disturbance, cognitive and mood impairment. Pain is a complex and multidimensional experience that significantly impacts personal, social, and professional functioning. Psychological factors related to chronic pain include catastrophising and self-efficacy in managing the painful condition. Therefore, this study explores the influence of chronic pain and related psychological factors on functional outcomes in FM patients. METHODS: In this study, 91 Italian patients with FM were assessed using an online questionnaire. The questionnaire included instruments to assess pain, such as the Numerical Rating Scale (NRS) and the Brief Pain Inventory (BPI), psychological characteristics, such as the Pain Self-Efficacy Questionnaire (PSEQ) and the Pain Catastrophizing Scale (PCS), and health-related quality of life with the 12-item Short Form Survey (SF-12). Multiple regression models were run, using the Interference subscale of the BPI and the physical and mental components of the SF-12 as outcomes, and the NRS, PCS and PSEQ scales as predictors. RESULTS: Our analysis revealed that in our model, both PCS and PSEQ were significant predictors of BPI-Interference (PCS: ß=0.29; p=0.001; PSEQ: ß=-0.36; p<0.001); NRS and PSEQ significantly predicted SF-12-Physical score (NRS: ß=-0.32; p=<0.001; PSEQ: ß=.50; p<0.001); PCS was found to be the only significant predictor of SF-12-Mental scores (ß=-0.53; p<0.001). CONCLUSIONS: Our results suggested that psychological variables such as catastrophic thinking and self-efficacy play a significant role in determining daily functioning and physical and mental health status in FM patients, showing greater influence than pain intensity.

Hub-and-Spoke Stroke System: Enhancing Acute Ischemic Stroke Care in the Philippines.

INTRODUCTION: The Hub-and-Spoke stroke system seeks to enhance the efficiency of stroke care by establishing a cohesive network between healthcare facilities providing quality stroke care to patients. This study endeavors to evaluate the effectiveness and characterize the outcomes of acute ischemic stroke patients treated within the Hub-and-Spoke hospital system over 2 years. The assessment focused on thrombolysis rates, mortality, and disability at 3-month follow-up. METHODS: We conducted a retrospective single-center review to assess the service delivery and outcomes of acute ischemic stroke patients within the Hub-and-Spoke framework which was implemented in Q3 2021. The Hub-and-Spoke model aimed to provide appropriate neurological care for stroke patients, growing from four to eight spoke hospitals in 2 years. RESULTS: The study consisted of 132 stroke patients transferred to the hub hospital, and 42 (31.8%) of them had acute ischemic stroke. Among these 42 ischemic stroke patients, 76% of them were candidates for thrombolysis with a mean NIHSS of 12 (6-22). Among the subset of 32 patients eligible for intervention within the specified time window, a total of 23 individuals, constituting 72% received r-TPA. Regarding patients administered r-TPA, 91.2% demonstrated favorable functional outcomes with an mRS score of 0-1, while 8.7% exhibited a score of 2-3. Among those not given r-TPA, the mean NIHSS was 17 (ranging from 2 to 32). Their functional outcomes after 3 months revealed 52.5% with an mRS score of 0-1, 16% with a score of 2-3, 21.2% with a score of 4-5, and 10.5% with an mRS score of 6. CONCLUSION: Hub-and-Spoke networks represent a crucial advancement in stroke treatment, particularly for facilities lacking the capacity to manage strokes effectively. By leveraging added expertise and reducing the time from onset to diagnosis to treatment, these networks have significantly enhanced patient care. This enhancement is particularly evident in the increased rate of thrombolysis, resulting in reduced morbidity and prevention of mortality.

Long-term outcomes of patients affected by Guillain-Barré syndrome in Colombia after the Zika virus epidemic.

BACKGROUND: Guillain-Barré Syndrome (GBS) can lead to significant functional impairments, yet little is understood about the recovery phase and long-term consequences for patients in low- and medium-income countries. OBJECTIVE: To evaluate the functional status and identify factors influencing outcomes among patients with GBS in Colombia. METHODS: Telephone interviews were conducted with GBS patients enrolled in the Neuroviruses Emerging in the Americas Study between 2016 and 2020. The investigation encompassed access to health services and functional status assessments, utilizing the modified Rankin Scale (mRS), GBS Disability Score (GDS), Barthel Index (BI), and International Classification of Functioning (ICF). Univariate analysis, principal component analysis, linear discriminant analysis, and linear regression were employed to explore factors influencing functional status. RESULTS: Forty-five patients (mean age = 50[±22] years) with a median time from diagnosis of 28 months (IQR = 9-34) were included. Notably, 22% and 16% of patients did not receive rehabilitation services during the acute episode and post-discharge, respectively. Most patients demonstrated independence in basic daily activities (median BI = 100, IQR = 77.5-100), improvement in disability as the median mRS at follow-up was lower than at onset (1 [IQR = 0-3] vs. 4.5 [IQR = 4-5], p < 0.001), and most were able to walk without assistance (median GDS = 2, IQR = 0-2). A shorter period from disease onset to interview was associated with worse mRS (p = 0.015) and ICF (p = 0.019). Negative outcomes on GDS and ICF were linked to low socioeconomic status, ICF to the severity of weakness at onset, and BI to an older age. CONCLUSIONS: This study underscores that the functional recovery of GBS patients in Colombia is influenced not only by the natural course of the disease but also by socioeconomic factors, emphasizing the crucial role of social determinants of health.

Factors influencing quality of life and functional status in head and neck cancer patients.

OBJECTIVE: To assess the quality of life (QoL) and functional status factors of patients at various stages of treatment for head and neck cancer. STUDY DESIGN: Cross-sectional survey study. SETTING: Outpatient. METHODS: Patients over the age of 18 who received care at the Markey Head and Neck Cancer Center Clinic since 2015 were invited to complete the survey. Survey items included: demographic information, characteristics of the patient's disease and treatments, as well as an 18-item survey assessing quality of life and functional status. A follow-up for each factor asked patients to rate how important it was to them. RESULTS: Patients reported greatest difficulties with physical activity (2.18), sleep (2.20), stress (2.26), and fatigue (2.26). Patients indicated that information (3.00), medication management (2.67), and sleep (2.62) were the most important. Multimodal therapy, marital status, and education level were all found to have statistically significant associations with several QoL measures. CONCLUSION: Quality of life and functional status in patients who have undergone treatment for head and neck cancer are both affected by many factors, particularly multimodal treatment, partner support, and education level. Identifying patients who may be more affected by treatment and targeting them with additional support and resources may lead to improved QoL in patients and their caregivers. This study would suggest that efforts to support physical activity, sleep, and stress management could lead to the most significant impact.

Adverse health effects of declined intrinsic capacity in middle-aged and older adults: a systematic review and meta-analysis.

BACKGROUND: Intrinsic capacity refers to a broad range of health traits, including the physiological and psychological changes brought on by aging. Previous research has shown that intrinsic capacity, as an independent emerging construct, is a highly effective predictor of several health outcomes. OBJECTIVE: We aimed to summarise the predictive effect of intrinsic capacity at baseline on health outcomes among middle-aged and older adults. DESIGN: A systematic review and meta-analysis. PARTICIPANTS: Middle-aged and older adults. METHODS: We systematically searched up to 3 April 2024 in 10 electronic databases. Studies investigating the predictive effect of baseline composite intrinsic capacity and health outcomes were included. Publications that had reported hazard ratios (HRs) or odd ratios (ORs) and 95% confidence intervals (CIs) as effect size were considered. RESULTS: A total of 23 publications were included. The sample size ranged from 100 to 17 031. The results of the meta-analysis showed statistically significant prediction of adverse health outcomes such as disability (OR = 1.84, 95% CI: 1.68-2.03, I2 = 41%, Pheterogeneity=.10), falls (OR = 1.38, 95% CI: 1.19-1.60, I2 = 45%, Pheterogeneity=.11), hospitalisation (OR = 2.25, 95% CI: 1.17-4.3, I2 = 68%, Pheterogeneity=.08), mortality (OR = 1.72, 95% CI: 1.54-1.91, I2 = 32%, Pheterogeneity=.12) and frailty (OR = 1.57, 95% CI: 1.45-1.70, I2 = 2%, Pheterogeneity=.31) by the baseline composite intrinsic capacity. CONCLUSIONS: Declined intrinsic capacity has potential predictive value for adverse health outcomes, further high-quality study is needed to validate these findings and strengthen their cumulative impact. Attention to health outcomes should also focus on both breadth and category precision.

Hearing Loss, Hearing Aids, and Functional Status.

Importance: Hearing loss may contribute to poor functional status via cognitive impairment and social isolation. Hearing aids may play a protective role by attenuating these downstream outcomes. However, population-based evidence is lacking. Objective: To examine the association of hearing loss and hearing aids with functional status. Design, Setting, and Participants: This cross-sectional (2016-2017) and longitudinal (2016-2022) analysis of data from the Atherosclerosis Risk in Communities cohort study included older, community-dwelling adults with complete data. Data were analyzed from June to December 2023. Exposures: The better-hearing ear's pure tone average (BPTA) at speech frequencies (0.5-4 kHz) was modeled categorically (no [BPTA ≤25 dB], mild [26-40 dB], and moderate or greater hearing loss [>40 dB]). Hearing aid use was self-reported. Main Outcomes and Measures: Difficulties in activities of daily living (ADLs; eg, dressing and eating), instrumental activities of daily living (IADLS; eg, household chores and meal preparation), and heavier tasks (eg, walking a quarter of a mile) were self-reported at visit 6. The ability to perform usual activities, walk a half mile, walk up and down stairs, and do heavy housework without help were collected in follow-up surveys. Linear and logistic regression models were used that were adjusted for sociodemographic and health covariates. Results: Among 3142 participants (mean [SD] age, 79.3 [4.6] years; 1828 women [58.2%]), 1013 (32.2%) had no hearing loss, 1220 (38.8%) had mild hearing loss, and 909 (29.0%) had moderate or greater hearing loss. Moderate or greater hearing loss was cross-sectionally associated with difficulty in 1 or more ADLs (odds ratio [OR], 1.27; 95% CI, 1.02-1.58), IADLs (OR, 1.34; 95% CI, 1.05-1.71), and heavier tasks (OR, 1.29; 95% CI, 1.04-1.62) compared with no hearing loss. Over time (mean [SD] follow-up, 1.9 [1.8] years), moderate or greater hearing loss was associated with a faster decline in the number of activities participants were able to do (ß = -0.07 per year; 95% CI, -0.09 to -0.06) and greater odds of reporting inability to do 1 or more of the 4 activities (OR, 1.14; 95% CI, 1.05-1.24). Hearing aid users and nonusers did not differ. Conclusions and Relevance: The results of this study suggest that moderate or greater hearing loss was associated with functional difficulties and may contribute to a faster decline in function longitudinally independent of sociodemographic and health covariates. Hearing aids did not change the association among those with hearing loss.

Association between the incidence of functional disability and frequency of eating together among older adults living alone: a 6-year follow-up study from the Japan Gerontological Evaluation Study.

OBJECTIVE: This study aimed to determine whether the frequency of eating together is associated with the incidence of functional disability in older adults who live alone. METHODS: This 6-year observational prospective cohort study utilised self-reported questionnaires. Data were drawn from the participants of the Japan Gerontological Evaluation Study project between 2016 and 2022. The participants were independent older adults aged ≥65 years living alone in Japan. The primary outcome was the incidence of functional disability during the follow-up period, with the self-reported frequency of eating together serving as the explanatory variable. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated using Cox proportional hazards models after adjusting for confounders associated with incident functional disability. RESULTS: Among the 7167 participants, the mean age at baseline was 75.3 ± 6.5 years and 69.2% were female. About, 12.8% of participants (n = 917) developed functional disabilities during the observation period. The incidence rates were 11.7% for 'every day', 11.3% for 'several times a week', 11.5% for 'several times a month', 12.7% for 'several times a year' and 19.0% for 'seldom'. The frequency of eating together 'seldom' was significantly associated with an increased incidence of functional disability (HR: 1.55, 95% CI: 1.10-2.18). CONCLUSION: Among older adults living alone, infrequent eating together ('seldom') was identified as a risk factor for developing functional disability.

Intrinsic Capacity and Its Biological Basis: A Scoping Review.

BACKGROUND: In 2015, the World Health Organization (WHO) introduced the concept of intrinsic capacity (IC) to define healthy aging based on functional capacity. In this scoping review, we summarized available evidence on the development and validation of IC index scores, the association of IC with health-related factors, and its biological basis. The review specifically focused on identifying current research gaps, proposed strategies to leverage biobank datasets, and opportunities to study the genetic mechanisms and gene-environment interactions underlying IC. METHODS: The literature search was conducted across six databases, including PubMed, CINAHL, Web of Science, Scopus, AgeLine, and PsycINFO, using keywords related to IC. RESULTS: This review included 84 articles, and most of them (n=38) adopted the 5-domains approach to operationalize IC, utilizing correlated five factors or bifactor structures. Intrinsic capacity has consistently shown significant associations with socio-demographic and health-related outcomes, including age, sex, wealth index, nutrition, exercise, smoking, alcohol use, ADL, IADL, frailty, multimorbidity, and mortality. While studies on the biological basis of the composite IC are limited, with only one study finding a significant association with the ApoE gene variants, studies on specific IC domains - locomotor, vitality, cognitive, psychological, and sensory suggest a heritability of 20-85% of IC and several genetic variants associated with these subdomains have been identified. However, evidence on how genetic and environmental factors influence IC is still lacking, with no available study to date. CONCLUSION: Our review found that there was inconsistency in the use of standardized IC measurement tools and indicators, but the IC indices had shown good construct and predictive validity. Research into the genetic and gene-to-environment interactions underlying IC is still lacking, which calls for the use of resources from large biobank datasets in the future.

Implementing Occupational Therapy into an Acute Geriatric Ward: Effects on Patients' Functional Status at Discharge.

Older patients face increasing challenges in preserving mobility during hospitalization. This retrospective cohort study aimed to evaluate the effect of an Occupational Therapy (OT) program on mobility at discharge in older patients admitted to an Acute Geriatric Unit (AGU). All patients aged ≥65 years consecutively admitted to the AGU in an 18-month period were included in the study if scoring <4 or ≥ 8 at the Clinical Frailty Scale. Overall, 807 patients (median age 85 years, 50.2% females) were included: 665 (82%) received OT, while 142 who did not receive OT were used as controls. The Cumulated Ambulation Scale (CAS) was used to assess mobility at discharge. By multivariable logistic regression, OT was independently associated with higher odds of achieving higher CAS score at discharge. These findings emphasize the potential benefits of OT in acute geriatric settings, providing valuable insights for preserving mobility of frail older individuals during hospitalization.

Web-Based Group Conversational Intervention on Cognitive Function and Comprehensive Functional Status Among Japanese Older Adults: Protocol for a 6-Month Randomized Controlled Trial.

BACKGROUND: Social communication is a key factor in maintaining cognitive function and contributes to well-being in later life. OBJECTIVE: This study will examine the effects of "Photo-Integrated Conversation Moderated by Application version 2" (PICMOA-2), which is a web-based conversational intervention, on cognitive performance, frailty, and social and psychological indicators among community-dwelling older adults. METHODS: This study is a randomized controlled trial with an open-label, 2-parallel group trial and 1:1 allocation design. Community dwellers aged 65 years and older were enrolled in the trial and divided into the intervention and control groups. The intervention group receives the PICMOA-2 program, a web-based group conversation, once every 2 weeks for 6 months. The primary outcome is verbal fluency, including phonemic and semantic fluency. The secondary outcomes are other neuropsychiatric batteries, including the Mini-Mental State Examination, Logical Memory (immediate and delay), verbal paired associates, and comprehensive functional status evaluated by questionnaires, including frailty, social status, and well-being. The effect of the intervention will be examined using a mixed linear model. As a secondary aim, we will test whether the intervention effects vary with the covariates at baseline to examine the effective target attributes. RESULTS: Recruitment was completed in July 2023. A total of 66 participants were randomly allocated to intervention or control groups. As of January 1, 2024, the intervention is ongoing. Participants are expected to complete the intervention at the end of February 2024, and the postintervention evaluation will be conducted in March 2024. CONCLUSIONS: This protocol outlines the randomized controlled trial study design evaluating the effect of a 6-month intervention with PICMOA-2. This study will provide evidence on the effectiveness of social interventions on cognitive function and identify effective target images for remote social intervention.

Beat-to-Beat Blood Pressure Variability Within 24 Hours of Ischemic Stroke Onset: A Potential Predictor of Functional Prognosis.

BACKGROUND: Beat-to-beat blood pressure variability (BPV) is based on each heartbeat and represents a dynamic equilibrium process modulated by artery and cardiac involvement of pressure-receptive reflexes. To date, there remains a lack of prospective studies illustrating the clinical value of beat-to-beat BPV within 24 hours of acute ischemic stroke onset. METHODS AND RESULTS: This study prospectively monitored beat-to-beat blood pressure and heart rate in patients with acute ischemic stroke within 24 hours of onset using a noninvasive plethysmograph and calculated beat-to-beat BPV, heart rate variability, and the cross-correlation baroreflex sensitivity. A modified Rankin Scale score of ≥2 at 90 days was defined as an unfavorable prognosis. Multivariate logistic regression was performed, and the nomogram model was developed by adding the beat-to-beat BPV to the traditional model for predicting prognosis. Beat-to-beat BPV increased significantly in the unfavorable outcome group (P<0.05) compared with that in the favorable outcome group, whereas no difference was observed in beat-to-beat heart rate variability and cross-correlation baroreflex sensitivity between both groups (P>0.05). Furthermore, beat-to-beat BPV within 24 hours of acute ischemic stroke onset was independently associated with unfavorable outcome at 90 days (P<0.005). The addition of beat-to-beat BPV to the traditional model for predicting prognosis enhanced the area under the receiver operating characteristic curve from 0.816 to 0.830. CONCLUSIONS: Increased beat-to-beat BPV within 24 hours of acute ischemic stroke onset was independently associated with a poor prognosis at 90 days and may be a potential predictor for discriminating unfavorable prognosis.

Morbidity and mortality of emergency surgery in octogenarian patient.

OBJECTIVE: To evaluate the health outcomes (postoperative morbidity and mortality) and the functional status at discharge of elderly patients older than 80 years who underwent emergency surgery. METHOD: Patients > 80 years of age who underwent emergency surgery during one year at the Marqués de Valdecilla University Hospital, Santander, Spain. Preoperative data (age, sex, type of surgery, comorbidity) and postoperative data (complications) were evaluated, as well as in-hospital mortality, at 30 days and 6 months after surgery. RESULTS: Five-hundred-sixty-eight patients underwent emergency surgery between 2018 and 2019. After the review, 407 patients were included in the study. Average age: 86.9 years. Women 61.7%. Mean hospital stay: 10.4 days. Traumatic interventions 41.3%, vascular surgery 19.7%, general-digestive surgery 25.3%. Medium ASA risk: 2.88. Functional status at discharge: 3.15. Postoperative complications: Clavien-Dindo I 40.8%, II 40.3%, IIIA 3.4%, IIIB 2.5%, IVA 3.9%, IVB 2.0% and V 7.1%. Hospital mortality 7.1%, 30-day mortality 10.3%, mortality at 6 months 24.6%. CONCLUSIONS: Patients > 80 years of age undergoing urgent surgery have high preoperative comorbidity, postoperative complications, and high mortality at 30 days and 6 months after surgery. This mortality is more significant in those ASA IV, nonagenarians and those undergoing high-risk surgery.

OBJETIVO: Evaluar los resultados en salud (morbilidad y mortalidad posoperatorias) y el estado funcional al alta de los pacientes mayores de 80 años sometidos a cirugía de urgencia. MÉTODO: Pacientes de edad > 80 años sometidos a cirugía de urgencia durante 1 año en el Hospital Universitario Marqués de Valdecilla, Santander, España. Se evaluaron datos preoperatorios (edad, sexo, tipo de cirugía, comorbilidad) y posoperatorios (complicaciones), así como mortalidad hospitalaria, a los 30 días y a los 6 meses de la cirugía. RESULTADOS: En 2018-2019 fueron operados de urgencia 568 pacientes, de los cuales 407 fueron incluidos en el estudio. Edad media: 86.9 años. El 61.7% fueron mujeres. Estancia media hospitalaria: 10.4 días. El 41.3% fueron intervenciones traumatológicas, el 19.7% cirugía vascular, el 25.3% cirugía general-digestiva. Riesgo ASA medio: 2.88. Estado funcional al alta: 3.15. Complicaciones posoperatorias: Clavien-Dindo I 40.8%, II 40.3%, IIIA 3.4%, IIIB 2.5%, IVA 3.9%, IVB 2.0% y V 7.1%. Mortalidad: hospitalaria 7.1%, a los 30 días 10.3% y a los 6 meses 24.6%. CONCLUSIONES: Los pacientes > 80 años sometidos a cirugía urgente presentan elevada comorbilidad preoperatoria, complicaciones posoperatorias y elevada mortalidad a 30 días y 6 meses de la cirugía. Esta mortalidad es más significativa en los ASA IV, nonagenarios y sometidos a cirugía de alto riesgo.
