The Evolving Landscape of Sarcopenia in Asia: A Systematic review and meta-analysis following the 2019 Asian working group for sarcopenia (AWGS) diagnostic criteria.

BACKGROUND: Sarcopenia, characterized by age-related loss of muscle mass and function, poses a significant public health concern, particularly in Asia's rapidly aging population. This systematic review and meta-analysis aimed to evaluate the current epidemiology of sarcopenia in Asia using the 2019 Asian Working Group for Sarcopenia (AWGS) diagnostic criteria. METHODS: Databases including PubMed, Embase, Web of Science, and Cochrane were systematically searched for studies published until December 7, 2023, involving older adults aged ≥ 60 years diagnosed with sarcopenia using the 2019 AWGS criteria in Asia. Study quality was assessed, and meta-analyses were conducted to estimate the pooled prevalence of sarcopenia, possible sarcopenia, and severe sarcopenia. RESULTS: A total of 140 studies, collectively involving 156,325 participants (67.1 % community-dwelling older adults with the minimum age for participant inclusion ranging from 60 to 80 years) from various Asian countries, were included. The overall prevalence of sarcopenia among community-dwelling older adults was 16.5 % (95 % CI: 14.7 %-18.4 %). Notably, the prevalence of possible sarcopenia was higher at 28.7 % (95 % CI: 22.0 %-36.5 %), while severe sarcopenia had a lower prevalence of 4.4 % (95 % CI: 3.3 %-5.8 %). Subgroup analyses revealed variations in sarcopenia prevalence based on diagnostic modalities, ranging from 7.5 % (95 % CI: 6.0 %-9.4 %) for assessments using bioelectrical impedance analysis, handgrip strength, gait speed, chair stand and short physical performance battery, to 20.8 % (95 % CI: 18.9 %-23.0 %) when using dual-energy X-ray absorptiometry coupled with muscle strength and physical performance measures. CONCLUSION: This comprehensive systematic review and meta-analysis highlights the substantial burden of sarcopenia among older adults in Asia, underscoring the need for early identification and intervention strategies to mitigate its adverse consequences on public health.

The correlation between frailty trajectories and adverse outcomes in older patients: A systematic review.

INTRODUCTION: Frailty is a geriatric syndrome that is highly susceptible to adverse health outcomes and is a major burden that exacerbates society's medical care. By investigating the frailty trajectory within the older demographic and initially recognizing its clinical outcomes, we will have more tactics to manage the at-risk population. METHODS: We executed a systematic review of trajectory studies elucidating the connection between frailty and adverse outcomes among older individuals (≥ 65 years) and explored articles published in English and Chinese from the inception of the database until Jun 30, 2024, in PubMed, Web of Science, Embase, The Cochrane Library, CINAHL, Scopus, CNKI, China Online Journals, VIP Information, and SinoMed. RESULTS: The database survey unearthed 3522 articles, of which 21 were deemed eligible. The majority incorporated distinct assessment tools and statistical methodologies to classify frailty trajectories into three groups. Although these frailty trajectories produced inconsistent clinical outcomes, they did reveal trends in the frailty status of older adults. CONCLUSION: The link between frailty trajectories and adverse outcome is a multifaceted and complex process that is currently understudied. More comprehensive and in-depth longitudinal studies should be conducted to explore the mechanism of interaction between the two to obstruct the progression of the frailty trajectory and bolster support for interventions.

Prognostic accuracy of eight frailty instruments for all-cause mortality in Australian primary care.

AIM: To investigate the ability of eight frailty instruments to accurately predict all-cause mortality and other adverse outcomes in Australian primary care patients. METHODS: Study participants included adults aged ≥75 years attending one of three primary care clinics in South Australia. Frailty instruments studied were Fried's frailty phenotype (FFP), the Frailty Index (FI) of cumulative deficits, Kihon Checklist (KCL), the Fatigue Resistance Ambulation Illness and Loss of weight (FRAIL) scale, Groningen Frailty Indicator (GFI), PRISMA-7, Reported Edmonton Frail Scale (REFS), and gait speed. Primary outcomes were all-cause mortality at 12- and 24-months. Secondary outcomes included falls, general practice attendance, hospital admission and emergency department (ED) presentation at 12-months. RESULTS: 243 participants (55.6 % female) with a mean (SD) age of 80.2 (4.6) years were included. 29 participants (16.6 %) were classified as frail at baseline by FFP. All frailty instruments demonstrated a significant ability to predict 12- and 24-month mortality. The REFS showed the highest auROC for both 12- and 24-month mortality. The REFS, Frailty Index, Kihon Checklist, FRAIL scale, and gait speed showed excellent discriminative ability for 12-month mortality (auROC ≥ 0.8 - >0.9), while the remainder showed acceptable discrimination. All frailty instruments, with the exception of the GFI, showed an excellent discriminative ability for 24-month mortality (auROC 0.8-<0.9). CONCLUSIONS: All frailty instruments possessed adequate discriminative ability for all-cause mortality predicting in older primary care patients. Frailty measurement is thus a valuable strategy to identify older patients at risk of mortality and can guide clinical decision-making in primary care settings.

Effectiveness of the frailty index in predicting short-term and long-term mortality risk in patients with chronic heart failure.

OBJECTIVE: This study explored the effectiveness of a newly constructed frailty index (FI) for predicting short-term and long-term mortality in patients with chronic heart failure (HF). MATERIALS AND METHODS: This retrospective study included inpatients aged ≥60 years diagnosed with chronic HF at a teaching hospital in western China. General data on the patients were collected from the electronic medical record system between January 1, 2017, and July 7, 2022, and death information was obtained from follow-up calls made from July 31, 2022, to August 1, 2022. Receiver operating characteristic (ROC) curves were used to analyze the accuracy of the FI in predicting death in patients with chronic HF. Logistic regression (during hospitalization and within 30 days after discharge) and Cox regression (within 180 days after discharge and one year after discharge) analyses were used to assess associations between frailty and mortality risk in elderly patients with chronic HF. RESULTS: A total of 432 patients with chronic HF were included in the study. The non-frail group had FI values <0.3, while the FI values in the frail group were ≥0.3. Overall, 130 patients (30.09 %) were diagnosed with frailty, 66 (15.28 %) died during hospitalization or within 30 days after discharge, 55 (12.73 %) died within 180 days after discharge, and 68 (15.74 %) died within one year after discharge. The in-hospital and 30-day mortality rates, the 180-day mortality rates, and the 1-year mortality rates were higher in frail patients than in non-frail patients (in-hospital and 30-day mortality rates, 37.69 % vs. 5.63 %, P < 0.001; within 180 days, 30.61 % vs. 8.45 %, P < 0.001; within 1 year, 34.69 % vs. 11.49 %, P < 0.001). The area under the curve (AUC) values of FI for predicting in-hospital and 30-day mortality after discharge were 0.804, with values of 0.721 for 180-day mortality after discharge and 0.720 for 1-year mortality after discharge. Logistic regression analysis with adjustment for potential confounders indicated that frail HF patients had a higher risk of death during hospitalization and within 30 days than non-frail patients (odds ratio [OR] = 4.98, 95 % confidence interval [CI]: 2.46-10.09). Cox regression analysis with adjustment for potential confounders showed that frail HF patients had a higher risk of death within 180 days (hazard ratio [HR] = 2.63, 95 %CI: 1.47-4.72) and within 1 year (HR = 2.01, 95 %CI: 1.19-3.38). CONCLUSION: The results of this study showed that the new FI constructed according to the established construction rules could predict the in-hospital mortality and the risk of death within 30 days after discharge, 180 days after discharge, and 1 year after discharge in patients with chronic HF.

Intrinsic capacity transitions as predictors of frailty transitions in community-dwelling older adults: Findings from the Korean Frailty and Aging Cohort Study.

BACKGROUND: Frailty is associated with reduced intrinsic capacity (IC). However, studies evaluating longitudinal transitions between IC and frailty are limited. We conducted longitudinal analyses to investigate the association between intrinsic capacity (IC) and frailty transitions among community-dwelling older adults in Korea. METHODS: A total of 2,345 older adults who completed baseline and two-year follow-up surveys were selected from the Korean Frailty and Aging Cohort Study. IC was measured in five domains: locomotion, vitality, cognition, psychology, and sensory function. Frailty was defined using the Fried frailty phenotype. Transitions in IC and frailty were assessed. Logistic regression analysis was used to analyze the association between baseline IC, IC transitions, and frailty transitions. RESULTS: During the two-year follow-up, 17.8 % of participants improved, 20.4 % worsened, and 61.8 % maintained the same frailty status. Low IC (odds ratio [OR]=1.93; 95 % confidence interval [CI]=1.42-2.61) significantly predicted remaining frail or worsening frailty. Worsened IC increased the risk of remaining frail or worsening frailty, whereas improved IC decreased this risk. Among the IC domains, the onset of new locomotion (OR=3.33; 95 % CI=2.39-4.64), vitality (OR=2.12; 95 % CI=1.55-2.91), and psychological (OR=3.61; 95 % CI=2.64-4.92) impairment predicted remaining frail or worsening frailty. CONCLUSIONS: Low and worsened IC were associated with an increased risk of remaining frail or worsening frailty over two years. These findings indicate that changes in IC can predict frailty transitions, thereby emphasizing the importance of enhancing IC in preventing frailty progression.

Cognitive functioning and falls in older people: A systematic review and meta-analysis.

OBJECTIVE: To identify which cognitive functions and specific neuropsychological assessments predict falls in older people living in the community. METHODS: Five electronic databases were searched until 30/08/2022 for studies assessing the association between specific cognitive functions and faller status (prospective and retrospective), in community-dwelling older people. Risk of bias was assessed with the Newcastle-Ottawa Scale. Meta-analyses synthesised the evidence regarding the associations between different neurocognitive subdomains and faller status. RESULTS: Thirty-eight studies (20 retrospective, 18 prospective) involving 37,101 participants were included. All but one study was rated high or medium quality. Meta-analyses were performed with data from 28 studies across 11 neurocognitive subdomains and four specific neuropsychological tests. Poor cognitive flexibility, processing speed, free recall, working memory and sustained attention were significantly associated with faller status, but poor verbal fluency, visual perception, recognition memory, visuo-constructional reasoning and language were not. The Trail Making Test B was found to have the strongest association with faller status. CONCLUSION: Poor performance in neurocognitive subdomains spanning processing speed, attention, executive function and aspects of memory are associated with falls in older people, albeit with small effect sizes. The Trail Making Test, a free-to-use, simple assessment of processing speed and mental flexibility, is recommended as the cognitive screening test for fall risk in older people.

The association between oral health and mild cognitive impairment in community-dwelling older adults.

Background: Older adults with cognitive impairment can experience poor oral health due to reduced self-care ability, yet the impact of various oral health indicators on the cognitive ability remains unclear. We investigated the relationship between oral health indicators and mild cognitive impairment (MCI) in older adults. Methods: A cross-sectional study of 234 older adults aged 65 years or over was performed form January to March 2023 at health screening departments of hospitals. This study used the Mini-mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Activities of Daily Living (ADL), Clinical Dementia Rating (CDR), and Hachinski Ischemic Score (HIS) to measure MCI. Two qualified dentists performed clinical oral examinations (number of teeth lost, dental caries, removable dentures, periodontitis). The other oral health status was measured by subjective assessment questionnaires, and the oral health-related quality of life (OHRQoL) was assessed by Geriatric Oral Health Assessment Index (GOHAI). Results: Of the 234 older adults, 166 had MCI and 68 had normal cognitive ability. The univariate analyses revealed that older adults with poor oral health indicators of dental caries, mastication ability, oral and maxillofacial pain, self-perceived oral health status and OHRQoL had lower cognitive levels. The stepwise logistic regression analysis observed that higher education level (OR = 0.06, 95%CI = 0.007, 0.567) and OHRQoL score (OR = 0.92, 95%CI = 0.878, 0.963) were negatively associated with the presence of MCI. The area under the ROC curve (AUC) of MCI was 0.675 (95% CI: 0.600, 0.749) with a low sensitivity of 41.6% and a moderate specificity of 86.8%. Conclusion: OHRQoL was found to be associated with MCI, implying that OHRQoL may be important in cognitive decline. The GOHAI scale can be used to more easily assess the oral health of older adults, which is important for the timely detection of poor oral status to delay cognitive decline.

Frailty transition and burden on mortality risk in middle-aged and older population: a prospective cohort study.

The effect of frailty transition and burden on the risk of all-cause mortality in South Korea remains unclear. This study aimed to investigate the risk of all-cause mortality using the most recent frailty index (FI), changes in FI, and frailty burden. We analyzed data from the Korean Genome and Epidemiology Study (2013-2020). A total of 3,134 participants aged 53-87 years with a computable FI based on the osteoporotic fracture index during their initial visit. The FI was updated biennially during re-examinations and changes between the initial and last visits were categorized into four groups: (1) improved or maintained to non-frail, (2) worsened to pre-frail, (3) improved or maintained to pre-frail, and (4) worsened or maintained to frail. We used the Cox proportional hazards model, adjusted for age, sex, education, lifestyle factors, and diseases. During the follow-up, 218 participants died. Compared to those who were robust at the last visit, pre-frailty and frailty were associated with an increased risk of all-cause death. Of those who visited > 2 times, 62.3% improved or remained robust, and had a decreased risk of all-cause death. Those with > 63% of pre-frailty or frailty burden significantly higher risk of death, with > 60% increase compared to their non-frail counterparts. Maintaining or achieving robustness is associated with a decreased risk of mortality. To prevent premature death and extend healthy life expectancy, identifying biological aging through surrogate measures and implementing interventions to maintain or achieve a robust health status are needed.

New horizons in hospital-associated deconditioning: a global condition of body and mind.

Hospital-associated deconditioning is a broad term, which refers non-specifically to declines in any function of the body secondary to hospitalisation. Older people, particularly those living with frailty, are known to be at greatest risk. It has historically been most commonly used as a term to describe declines in muscle mass and function (i.e. acute sarcopenia). However, declines in physical function do not occur in isolation, and it is recognised that cognitive deconditioning (defined by delayed mental processing as part of a spectrum with fulminant delirium at one end) is commonly encountered by patients in hospital. Whilst the term 'deconditioning' is descriptive, it perhaps leads to under-emphasis on the inherent organ dysfunction that is associated, and also implies some ease of reversibility. Whilst deconditioning may be reversible with early intervention strategies, the long-term effects can be devastating. In this article, we summarise the most recent research on this topic including new promising interventions and describe our recommendations for implementation of tools such as the Frailty Care Bundle.

Geriatric Oral Health and Quality of Life Among the Indigenous Irula Tribes of Tamil Nadu.

OBJECTIVES: This study aims to assess the oral health-related quality of life (OHRQoL) among the Irula tribes and to know the factors influencing quality of life among the elderly irula tribes of Tamil Nadu. METHODS: This cross-sectional study was conducted in the Northern district of Tamil Nadu, including 486 Irula individuals aged 65 and above. Participants were selected using a multistage sampling method. Data were collected through a structured questionnaire, including the Geriatric Oral Health Assessment Index (GOHAI) to evaluate OHRQoL. The study tool covered demographics, medical history, and oral health issues. Data analysis was performed using SPSS version 23, with logistic regression applied to account for confounders. RESULTS: The sample primarily consisted of individuals aged 65-69 years (55.6%), with a predominance of females (76.3%). The majority were Hindu (94.9%) and lived in nuclear families (88.3%). Educational levels were low, with 66.5% being illiterate. Most participants were agricultural laborers (64.6%) and had low monthly incomes. GOHAI results revealed that many respondents faced significant oral health challenges, including difficulties with eating, speaking, and discomfort. Multivariate analysis showed that educational level significantly affected OHRQoL, with higher education correlating with better quality of life. Arthritis was associated with poorer OHRQoL, while other health conditions did not show significant impacts. CONCLUSION: The study highlights severe oral health issues among the Irula community, with significant physical and psychological impacts. Educational attainment plays a crucial role in OHRQoL, while arthritis notably affects quality of life. The findings emphasize the need for targeted oral health interventions and increased awareness in tribal communities to improve overall health outcomes. Further research in larger populations is necessary to comprehensively understand and address geriatric oral health needs.

Integrated care for older people improved intrinsic capacity in elderly patients: a case control study.

OBJECTIVES: Observe the effect of integrated care for older people on intrinsic capacity in elderly patients. METHODS: Sixty elderly patients from department of Geriatrics, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology between June 2021 and December 2021 were selected and divided into control group and intervention group with 30 patients in each group using random sampling method. Two groups implement routine care, and the intervention group implement integrated care by a "hospital-community-family" multidisciplinary team. After 12 weeks of intervention, the differences in frailty, cognition, depression scores, comprehension social support scores, and World Quality of Life Scale scores were compared between the two groups. RESULTS: Before intervention, there was no significant difference in the grip strength, step speed, frailty scores, cognition, depression scores, social support and quality of survival between the control group and the intervention group. After intervention, grip strength and depression scores improved both in the control group and the intervention group, but there was no difference between the two groups. Cognitive scores, comprehension social support and quality of survival scores improved only in the intervention group, while only the cognitive ability showed significant differences between the intervention group and the control group after 12 weeks of intervention (P<0.05). CONCLUSIONS: Integrated care for older people intervention can help to improve the intrinsic capacity of the patients, especially cognitive abilities.

Characteristics of and Risk Factors for Depressive Symptoms Preceding Dementia: A Study of 82-Year-Old Men From the Uppsala Longitudinal Study of Adult Men.

BACKGROUND: Depression and dementia are known to be associated. The identification of characteristics distinguishing depression prodromal to dementia from other depressive symptoms would be of value for early identification of dementia. The study of risk factors for depressive symptoms prodromal to dementia could improve preventive care and provide clues to the causes of dementia. METHOD: Dementia-free 82-year-old participants were stratified into groups that did (n = 126) and did not (n = 378) subsequently develop dementia. Examinations took place from 2003 to 2005 and follow-up ended 1 January 2015. Their baseline characteristics and depressive symptoms, measured using the 15-item Geriatric Depression Scale (GDS-15), were compared. Multivariate regression analyses were performed for the two groups separately, with the total GDS-15 score as the dependent variable. RESULTS: The groups did not differ significantly in answers to any of the GDS-15 questions, or mean ± SD score, which was 2.4 ± 2.5 among those who developed dementia and 2.1 ± 2.3 among those who did not. (p = 0.33). Stroke before the age of 82 years and the inability to use stairs had significant impacts on the GDS-15 scores in both groups. For those who did not develop dementia, age, dependence in activities of daily living, and cancer also had significant impacts. Cancer had opposite associations with depressive symptoms in the two groups. CONCLUSIONS: No difference was found in depressive symptoms preceding and not preceding dementia using the GDS-15. The results suggest that risk factors for depressive symptoms may differ depending on whether they precede dementia.

Preoperative frailty tendency predicts delirium occurrence in older people undergoing spinal surgery.

BACKGROUND: This prospective cohort study focused on the predictive value of frailty or pre-frailty assessed by Edmonton Frailty Scale (EFS) for postoperative delirium in spinal surgery patients. METHODS: The primary outcome measurement was postoperative delirium (POD) evaluated by Confusion Assessment Method at day 1, day 2, and day 3 after the surgery. Secondary outcomes included severity and duration of POD, severe postoperative pain measured by Faces Pain Scale-Revised. Patients scheduled for elective spinal surgery were enrolled and assessed for frailty by EFS before surgery. Demographic data, preoperative, intraoperative, and postoperative information were collected. RESULTS: 231 out of 325 patients were enrolled and analyzed in this study at last. The cohort with 36.8% being frail and 28.5% being vulnerable. Postoperative delirium was detected in 41 in 231 patients. Multivariate logistic regression analysis revealed that vulnerable to frailty (OR = 4.681, 95% CI: 1.199 to 18.271, P = 0.026), after adjusted duration of surgery more than 3 h, using flumazenil at the end of surgery, using butorphanol only in postoperative patient-controlled intravenous analgesia, moderate-to-severe pain at day 1 and 2, is a strong predictor of postoperative delirium. Frailty was associated with longer duration (frailty vs. fit, P = 0.364) and stronger severity of postoperative delirium in the first two days (P < 0.001). High EFS score was independent risk factor of severe postoperative pain (Frailty vs. Fit: OR = 5.007, 95% CI: 1.903 to 13.174, P = 0.001; Vulnerable vs. Fit: OR = 2.525, 95% CI: 1.008 to 6.329, P = 0.048). In stratified tests, Sufentanil regimen in intravenous PCA significantly increase the proportion of POD in vulnerable group (P = 0.030), instead of frailty group (P = 0.872) or fit group (P = 0.928). CONCLUSIONS: Frailty can increase the risk, severity, duration of delirium and severe postoperative pain in the first 3 days after surgery of patients. TRIAL REGISTRATION: The protocol of this study has been approved by the Ethic Committee of Shanghai Changzheng Hospital (Approval file number: 2022SL044) and informed consent was obtained from all the patients. The trial was retrospectively registered at chictr.org.cn (ChiCTR2300073306) on 6th July 2023.

Clinical Frailty Scale score is a predictor of short-, mid- and long-term mortality in critically ill older adults (≥ 70 years) admitted to the emergency department: an observational study.

BACKGROUND: The estimated prognos of a patient might influence the expected benefit/risk ratio of different interventions. The main purpose of this study was to investigate the Clinical Frailty Scale (CFS) score as an independent predictor of short-, mid- and long-term mortality in critically ill older adults (aged ≥ 70) admitted to the emergency department (ED). METHODS: This is a retrospective, single-center, observational study, involving critically ill older adults, recruited consecutively in an ED. All patients were followed for 6.5-7.5 years. The effect of CFS score on mortality was adjusted for the following confounders: age, sex, Charlson's Comorbidity Index, individual comorbidities and vital parameters. All patients (n = 402) were included in the short- and mid-term analyses, while patients discharged alive (n = 302) were included in the long-term analysis. Short-term mortality was analysed with logistic regression, mid- and long-term mortality with log rank test and Cox proportional hazard models. The CFS was treated as a continuous variable in the primary analyses, and as a categorical variable in completing analyses. RESULTS: There was a significant association between mortality at 30 days after ED admission and CFS score, adjusted OR (95% CI) 2.07 (1.64-2.62), p < 0.0001. There was a significant association between mortality at one year after ED admission and CFS score, adjusted HR (95% CI) 1.75 (1.53-2.01), p < 0.0001. There was a significant association between mortality 6.5-7.5 years after discharge and CFS score, adjusted HR (95% CI) 1.66 (1.46-1.89), p < 0.0001. Adjusted HRs are also reported for long-term mortality, when the CFS was treated as a categorical variable: CFS-score 5 versus 1-4: HR (95% CI) 1.98 (1.27-3.08); 6 versus 1-4: HR (95% CI) 3.60 (2.39-5.44); 7 versus 1-4: HR (95% CI) 3.95 (2.38-6.55); 8-9 versus 1-4: HR (95% CI) 20.08 (9.30-43.38). The completing analyses for short- and mid-term mortality indicated a similar risk-predictive value of the CFS. CONCLUSIONS: Clinical frailty scale score was independently associated with all-cause short-, mid- and long-term mortality. A nearly doubled risk of death was observed in frail patients. This information is clinically relevant, since individualised treatment and care planning for older adults should consider risk of death in different time perspectives.

Associations between the geriatric nutritional risk index and the risk of and mortality associated with chronic kidney disease in older individuals.

BACKGROUND: Malnutrition is a complication of chronic kidney disease (CKD). Whether malnutrition, assessed via the geriatric nutritional risk index (GNRI), is associated with the incidence and risk of CKD in older individuals remains unclear. METHODS: Data from the National Health and Nutrition Examination Survey and the UK Biobank database were used. Older participants over 60 years old with available data for GNRI assessment and CKD diagnosis were enrolled. Logistic regression models and Cox regression models were used to assess associations between the geriatric nutritional risk index and the risk of and mortality associated with CKD. RESULTS: This study enrolled 13,162 participants from the NHANES and 66,326 participants from the UK Biobank. We identified 6,135 and 16,662 CKD patients in the NHANES and UK Biobank, respectively, with the majority being male (74% in the NHANES and 52% in the UK Biobank). The average age of CKD patients was 72.3 (SD 7.2) years in the NHANES and 64.9 (SD 2.9) years in the UK Biobank. The median follow-up times of older CKD patients were 81 months and 162 months in the NHANES and UK Biobank, respectively. According to the cross-sectional analysis, individuals with a lower GNRI had an increased likelihood of having CKD, with odds ratios of 1.38 (95% CI: 1.05-1.80, P = 0.020) in the NHANES and 2.35 (95% CI: 1.89-2.92, P < 0.001) in the UK Biobank. According to our analysis of the risk of incident CKD in the UK Biobank, a lower GNRI was associated with a greater incidence of CKD (HR: 1.11, 95% CI: 1.04-1.18; P = 0.002). According to the analysis of the risk of mortality, a lower GNRI was associated with an increased risk of death among older CKD patients (NHANES: HR: 1.69, 95% CI: 1.13-2.53, P = 0.011; UK Biobank: HR: 2.28, 95% CI: 1.94-2.69, P < 0.001). CONCLUSION: Malnutrition assessed by the GNRI was significantly and independently associated with the incidence of CKD. Moreover, CKD patients with malnutrition also have a high risk of mortality.

[Adaptive Behavior is Related to Body Adiposity and Functional Fitness in Older Women]. / El comportamiento adaptativo se relaciona con la adiposidad corporal y la aptitud funcional en mujeres de la tercera edad.

Older people present limited independent functioning and greater difficulties in their activities of daily living as they age. AIM: To determine whether indicators of body adiposity and functional fitness are related to adaptive behavior in Chilean elderly women. METHODS: A descriptive cross-sectional study was carried out in 162 elderly adult women. Body adiposity (BA) was determined by body mass index (BMI) and fat mass (FM). Functional fitness (FA) was assessed by means of four physical tests: Arm flexibility, 30-second right arm strength endurance (RFBD), 30-second chair stand (up-and-go) test and the agility test (2.44 m). Adaptive behavior (AC) was assessed using a scale called AC Self-Perception of AC for Women (ACAM). RESULTS: There were negative correlations between AC with chronological age, BMI, MG, and Agility (∼ r= -0.27 to -0.45, p<0.05), while the relationship was positive with leg strength, flexibility, and RFBD (∼ r= 0.17 to 0.26, p<0.05). Comparisons of CA and PA between CA categories were small and medium. The effect size between women categorized as low and high CA was medium (∼ 0.31 to -0.46). However, among women categorized with medium and high CA level it was small (∼ 0.07 to -0.30). CONCLUSION: The study found that, in women aged 65-84 years, AC tends to decrease with age, while body adiposity increases and functional fitness decreases. It is recommended to implement strategies that address these negative effects of aging, such as prevention and management of body adiposity, functional exercise programs, and promotion of a healthy lifestyle.

[Nutritional Status of Institutionalized Elderly and Its Relationship with Functional Status During 2019]. / Estado nutricional de personas mayores institucionalizadas y su relación con el estado funcional durante el año 2019.

Aging is associated with physiological, economic, and psychological changes that can compromise nutritional and functional status. AIM: To determine the nutritional status of institutionalized older people living in a long-term nursing home "Fundación las Rosas" (FLR), the largest long-stay establishment in Chile, in 2019, and its relationship with functionality. METHODS: Descriptive study of analysis of secondary data in 1646 older adults institutionalized in FLR (60% women). The information collected was weight, height, Body mass index (BMI), Barthel Index, Mini-Mental State Examination, area, macrozone, sex, age, and date of admission to FLR. Logistic regression models of functionality and nutritional status, unadjusted and adjusted, were performed. RESULTS: The percentage of normal-weight people was 40.3%; 38.1% presented some degree of malnutrition due to deficit, and 9.5% presented severe malnutrition (BMI≤18.5 kg/m2). 70% of people present total dependency. The low educational level reached 73%. Logistic regressions determined that people who were overweight, 70 years of age or older, had a low level of education, and cognitive impairment were positively associated with dependency, excluding bedridden people, with the strongest associations being not having any level of schooling and having cognitive impairment. The persons of low weight, with cognitive impairment, and with a low educational level were positively associated with institutionalized bedridden elderly, the strongest associations being not having any level of schooling and having cognitive impairment. CONCLUSIONS: In this study, malnutrition due to deficit and excess are positively associated with decreased functionality, and a low educational level is associated with dependency and being bedridden.

Frailty prevalence in older adults with atrial fibrillation: A cross-sectional study in a resource-limited setting.

BACKGROUND/OBJECTIVES: Frailty is a common condition among older adults and is associated with an increased risk of adverse health outcomes, including mortality, disability, dysmobility, falls, and hospitalization. In patients with atrial fibrillation (AF), these risks are further exacerbated. However, evidence linking AF and frailty, particularly in the South American context, is limited. This study aimed to assess frailty and other geriatric conditions in older outpatients with atrial fibrillation in a resource-limited setting in Lima, Peru. METHODS: In this cross-sectional study, we included adults aged 60 years and older diagnosed with atrial fibrillation who were attending outpatient check-ups. Patients who were hospitalized, receiving chemotherapy induction, or presenting with acute infections or exacerbations were excluded. Standardized questionnaires were used to assess frailty, cognitive impairment, and functional dependence. Statistical analysis was performed using R Studio version 4.3.1, with a significance level set at p < 0.05. RESULTS: Among the 200 patients who agreed to participate (mean age 74.76 ± 8.42 years, 41% females), 28.5% exhibited frailty, and 46.5% were classified as prefrail. Frailty and prefrailty were significantly associated with older age (p<0.01), female gender (p = 0.01), illiteracy (p<0.01), heart failure (p<0.01), falls (p<0.05), cognitive impairment (p<0.01), and functional dependence (p<0.01). Multivariate analysis revealed significant associations between frailty and cognitive impairment (p<0.05), frailty and functional dependence (p<0.05), and cognitive impairment and functional dependence (p<0.05). CONCLUSIONS: One-third of older outpatients with atrial fibrillation were identified as frail, while half were classified as prefrail. In this population, frailty frequently coexists with cognitive impairment and functional dependence, highlighting the need for timely screening and the implementation of evidence-based interventions for individuals with atrial fibrillation in resource-limited settings.

Application of the world guidelines for falls prevention and management's risk stratification algorithm to patients on a frailty intervention pathway and the potential utility of sensory impairment information.

BACKGROUND: The 2022 world guidelines for falls prevention and management suggest measuring sensory function including dizziness, vision, and hearing. These variables are not included in the falls risk stratification algorithm. This study sought to investigate the utility of the guidelines and potential avenues for improvement. This study applied the falls risk stratification recommendations and reviewed the individual sensory impairment risk factor variables predictive of falls and falls risk grouping in those assessed by a frailty intervention team (FIT) based in an emergency department (ED). METHODS: Patients over 65 years old who attended the ED and had a comprehensive geriatric assessment carried out by FIT over a period of four months were included in this retrospective cross-sectional study. Patient characteristics, medication, physical and sensory function status data was retrieved and analysed with respect to falls and falls risk grouping. RESULTS: Data was gathered retrospectively from 392 patients. Excluding those with missing data, almost all attendees were in the high-risk of falls category (n = 170, 43.4%), or the low-risk category (n = 149, 38.0%). Few people were in the intermediate-risk category (n = 19, 4.8%). Hearing loss and dizziness were significantly associated with falls incidence, whereas vision and balance were not. Hearing loss, balance and dizziness were significantly associated with risk grouping, whereas vision was not. CONCLUSIONS: Most older adults included in the analysis fell into the low- or high-risk categories, with a minority in the intermediate-risk category. This suggests that the inclusion criteria for the intermediate category could be altered for greater sensitivity. While impaired balance and vision were the most common impairments, hearing status, balance and dizziness were associated with risk group. These results, through a practical application of the world guidelines for falls to an acute clinical sample, raise the possibility of refining the falls risk stratification criteria, and highlight the capacity for additional sensory intervention to mitigate falls risk.

Development and validation of a dynamic nomogram for high care dependency during the hospital-family transition periods in older stroke patients.

BACKGROUND: This research aimed to develop and validate a dynamic nomogram for predicting the risk of high care dependency during the hospital-family transition periods in older stroke patients. METHODS: 309 older stroke patients in the hospital-family transition periods who were treated in the Department of Neurology outpatient clinics of three general hospitals in Jinzhou, Liaoning Province from June to December 2023 were selected as the training set. The patients were investigated with the General Patient Information Questionnaire, the Care Dependency Scale (CDS), the Tilburg Frailty Inventory (TFI), the Hamilton Anxiety Rating Scale (HAMA), the Hamilton Depression Rating Scale-17 (HAMD-17), and the Mini Nutrition Assessment Short Form (MNA-SF). Lasso-logistic regression analysis was used to screen the risk factors for high care dependency in older stroke patients during the hospital-family transition period, and a dynamic nomogram model was constructed. The model was uploaded in the form of a web page based on Shiny apps. The Bootstrap method was employed to repeat the process 1000 times for internal validation. The model's predictive efficacy was assessed using the calibration plot, decision curve analysis curve (DCA), and area under the curve (AUC) of the receiver operator characteristic (ROC) curve. A total of 133 older stroke patients during the hospital-family transition periods who visited the outpatient department of Neurology of three general hospitals in Jinzhou from January to March 2024 were selected as the validation set for external validation of the model. RESULTS: Based on the history of stroke, chronic disease, falls in the past 6 months, depression, malnutrition, and frailty, build a dynamic nomogram. The AUC under the ROC curves of the training set was 0.830 (95% CI: 0.784-0.875), and that of the validation set was 0.833 (95% CI: 0.766-0.900). The calibration curve was close to the ideal curve, and DCA results confirmed that the nomogram performed well in terms of clinical applicability. CONCLUSION: The online dynamic nomogram constructed in this study has good specificity, sensitivity, and clinical practicability, which can be applied to senior stroke patients as a prediction and assessment tool for high care dependency. It is of great significance to guide the development of early intervention strategies, optimize resource allocation, and reduce the care burden on families and society.
