Frailty in community-dwelling older adults: association with adverse outcomes

Overlap between Osteosarcopenia and Frailty and their Association with Poor Health Conditions: The Bushehr Elderly Health Program

BACKGROUND

The aim of this study was to investigate the association of osteosarcopenia with frailty and poor health conditions among older Iranian adults.

METHODS

This cross-sectional study analyzed data from the Bushehr Elderly Health Program. Osteosarcopenia was defined as the presence of osteopenia/osteoporosis and sarcopenia, while the Fried criteria were used to assess frailty. We assessed the history of falls and health-related quality of life (HRQoL), including physical and mental component summaries (PCS and MCS, respectively), history of fractures, activities of daily living (ADL), and instrumental activities of daily living (IADL), as indicators of poor health conditions.

RESULTS

This study included a total of 2,371 older adults. The prevalence rates of osteosarcopenia-only, frailty-only, and osteosarcopenia with frailty were 17.4%, 3%, and 4.8%, respectively. The prevalence of a history of falls, poor ADL, and poor IADL was significantly higher in the frailty-only and osteosarcopenia with frailty groups. Osteosarcopenia with frailty was significantly associated with a history of falls (adjusted odds ratio [adjOR]=1.94; 95% confidence interval [CI], 1.20-3.15), poor ADL (adjOR=2.85; 95% CI, 1.81-4.50), and poor IADL (adjOR=5.09; 95% CI, 2.85-9.11). However, the frailty-only group also showed an association with falls and poor ADL and IADL. Only osteosarcopenia was associated with an increased OR for fracture. Frailty had the greatest effect on the MCS and PCS scores, whereas osteosarcopenia with frailty had a moderate impact.

CONCLUSION

Osteosarcopenia with frailty significantly increased the odds of falls, poor ADL, poor IADL, and lower HRQoL compared with the robust group. Combined osteosarcopenia and frailty were not associated with poor health. These findings indicate the importance of diagnosing osteosarcopenia and frailty as separate entities to provide appropriate interventions and treatment.

Frailty-originated early rehabilitation reduces postoperative delirium in brain tumor patients: Results from a prospective randomized study

Objective

To investigate the impact of frailty-originated, evidence-based early activity training on postoperative delirium in patients who have undergone brain tumor resection.

Methods

A randomized controlled trial was conducted at the Second Affiliated Hospital of Zhejiang University School of Medicine, from July 2019 to June 2020. Data on the patients' general information, incidence and duration of delirium, duration of hospital stay, and activities of daily living were collected. From the first day after surgery, the patients were randomly assigned to either the traditional care group or the frailty-originated rehabilitation towards intracranial tumors using distinct evidence (FORTITUDE) group. Non-parametric, chi-square, and log-rank tests were used to compare the onset time and duration of postoperative delirium and activities of daily living performed by the participants between the two groups.

Results

In total, 291 patients, 150 and 141 in the control group and FORTITUDE group, respectively, participated in the study. Patients in the FORTITUDE group had a lower incidence of postoperative delirium (15.6% vs. 28.7%, P ​= ​0.007), delayed onset of delirium (Z ​= ​-2.108, P ​= ​0.035), shorter duration of postoperative delirium (χ² ​= ​26.67, P ​< ​0.001), shorter hospital stay (Z ​= ​-2.037, P ​= ​0.042), and higher scores in the activities of daily living one week (Z ​= ​-2.304, P ​= ​0.021) and one month (Z ​= ​-2.724, P ​= ​0.006) after surgery than in the control group.

Conclusions

The FORTITUDE program was safe and effective in reducing the incidence and duration of postoperative delirium and improving the quality of life of patients who underwent brain tumor resection.

Low ALT, a marker of sarcopenia and frailty, is associated with shortened survival amongst myelodysplastic syndrome patients: A retrospective study

Myelodysplastic Syndrome (MDS) is a common blood dyscrasia that mainly affects the elderly population. Several prognostic scores are available utilizing blood count variables and cytogenetic abnormalities, targeting the disease rather than the patient. Sarcopenia and frailty are associated with shortened survival rates in various disease states. Low Alanine Aminotransferase (ALT) levels are a marker of lowered muscle mass and frailty status. This study aimed to examine the correlation between low ALT levels and prognosis in MDS patients. This is a retrospective cohort study. We obtained the demographic, clinical, and laboratory data of patients in a tertiary hospital. Univariate and multivariate models were used to investigate the potential relationship between low ALT level and survival. The final study included 831 patients (median age 74.3 years, Interquartile range 65.6-81.8), and 62% were males. The median ALT level was 15 international units (IU)/L and 233 patients (28%) had low ALT levels (<12 IU/L). Univariate analysis showed that low ALT levels were associated with a 25% increase in mortality (95% confidence interval [CI]: 1.05-1.50, P = .014). A multivariate model controlling for age, sex, body mass index, hemoglobin and albumin concentrations, and low ALT levels was still significantly associated with increased mortality (hazard ratio [HR] = 1.25, 95% CI: 1.01-1.56, P = .041). Low ALT levels were associated with increased mortality among patients with MDS. Impact: Using ALT as a frailty metric may allow patient-centered, personalized care in this patient population. A low ALT level reflects the pre-morbid robustness of patients and is not intended to replace disease-centered characteristics.

Insomnia Impairs Both the Pro-BDNF and the BDNF Levels Similarly to Older Adults with Cognitive Decline: An Exploratory Study

Sleep disorders, including insomnia, are common during aging, and these conditions have been associated with cognitive decline in older adults. Moreover, during the aging process, neurotransmitters, neurohormones, and neurotrophins decrease significantly, leading to the impairment of cognitive functions. In this sense, BDNF, the most abundant neurotrophic factor in the human brain, has been suggested as a potential target for the prevention and improvement of cognitive decline during aging; however, the current evidence demonstrates that the exogenous administration of BDNF does not improve cognitive function. Hence, in the present study, we quantified pro-BDNF (inactive) and BDNF (active) concentrations in serum samples derived from older individuals with insomnia and/or cognitive decline. We used linear regression to analyze whether clinical or sociodemographic variables impacted the levels of BNDF concentration. We observed that insomnia, rather than cognitive decline, is significantly associated with BDNF concentration, and these effects are independent of other variables. To our knowledge, this is the first study that points to the impact of insomnia on improving the levels of BDNF during aging and suggests that opportune treatment of insomnia may be more beneficial to prevent cognitive decline during aging.

Inflammation and Oxidative Stress in Frailty and Metabolic Syndromes-Two Sides of the Same Coin

In developed countries, aging is often seen as typical, but it is made complicated by many disorders and co-morbidities. Insulin resistance seems to be an underlying pathomechanism in frailty and metabolic syndromes. The decline in insulin sensitivity leads to changes in the oxidant-antioxidant balance and an accelerated inflammatory response, especially by adipocytes and macrophages in adipose tissue, as well as muscle mass density. Thus, in the pathophysiology of syndemic disorders-the metabolic syndrome and frailty syndrome-an extremely important role may be played by increased oxidative stress and pro-inflammatory state. Papers included in this review explored available full texts and the reference lists of relevant studies from the last 20 years, before the end of 2022; we also investigated the PubMed and Google Scholar electronic databases. The online resources describing an elderly population (≥65 years old) published as full texts were searched for the following terms: "oxidative stress and/or inflammation", "frailty and/or metabolic syndrome". Then, all resources were analyzed and narratively described in the context of oxidative stress and/or inflammation markers which underlie pathomechanisms of frailty and/or metabolic syndromes in elderly patients. So far, different metabolic pathways discussed in this review show that a similar pathogenesis underlies the development of the metabolic as well as frailty syndromes in the context of increased oxidative stress and acceleration of inflammation. Thus, we argue that the syndemia of the syndromes represents two sides of the same coin.

Association of Depressive Mood and Frailty With Mortality and Health Care Utilization: Korean National Cohort Study

OBJECTIVES

To investigate the association of depressive mood and frailty with mortality and health care utilization (HCU) and identify the coexisting effect of depressive mood and frailty in older adults.

DESIGN

A retrospective study using nationwide longitudinal cohort data.

SETTING AND PARTICIPANTS

A total of 27,818 older adults age 66 years from the National Screening Program for Transitional Ages between 2007 and 2008, part of the National Health Insurance Service-Senior cohort.

METHODS

Depressive mood and frailty were measured by the Geriatric Depression Scale and Timed Up and Go test, respectively. Outcomes were mortality and HCU, including long-term care services (LTCS), hospital admissions, and total length of stay (LOS) from the index date to December 31, 2015. Cox proportional hazards regression and zero-inflated negative binomial regression were performed to identify differences in outcomes by depressive mood and frailty.

RESULTS

Participants with depressive mood and frailty represented 50.9% and 2.4%, respectively. The prevalence of mortality and LTCS use in the overall participants was 7.1% and 3.0%, respectively. More than 3 hospital admissions (36.7%) and total LOS above 15 days (53.2%) were the most common. Depressive mood was associated with LTCS use [hazard ratio (HR) 1.22, 95% confidence interval (CI) 1.05-1.42] and hospital admissions [incidence rate ratio (IRR) 1.05, 95% CI 1.02-1.08]. Frailty had associations with mortality risk (HR 1.96, 95% CI 1.44-2.68), LTCS use (HR 4.86, 95% CI 3.45-6.84), and LOS (IRR 1.30, 95% CI 1.06-1.60). The coexistence of depressive mood and frailty was associated with increased LOS (IRR 1.55, 95% CI 1.16-2.07).

CONCLUSIONS AND IMPLICATIONS

Our findings highlight the need to focus on depressive mood and frailty to reduce mortality and HCU. Identifying combined problems early in older adults may contribute to healthy aging by reducing adverse health outcomes and the burden of health care costs.

Fundamental nursing actions for frail older people in the emergency department: A national cross-sectional survey and a qualitative analysis of practice guidelines

AIMS

To map how frailty among older people is assessed at Swedish emergency departments and to describe fundamental nursing care actions for these patients.

DESIGN

Descriptive national survey and a qualitative analysis of text.

METHODS

A majority (82%, n = 54) of the Swedish hospital-based emergency departments for adults were included, representing all six healthcare regions. An online survey was used to collect data, together with submitted local practice guidelines for older people at the emergency departments. Data were collected during February-October 2021. Descriptive and comparative statistics were performed together with a deductive content analysis framed by the Fundamentals of Care framework.

RESULTS

Sixty-five per cent (35 of 54) of the emergency departments identified frailty, with less than half of them using an established assessment instrument. Twenty-eight (52%) of the emergency departments have practice guidelines containing fundamental nursing actions for the care of frail older people. The majority of nursing actions in the practice guidelines were related to patients' physical care needs (91%), followed by psychosocial care needs (9%). No actions could be identified as relational actions (0%) according to the Fundamentals of Care framework.

CONCLUSION

Many Swedish emergency departments identify frail older people, but they use a range of different assessment instruments. While practice guidelines directing fundamental nursing actions for frail older people are often in place, a holistic, person-centred view addressing the patient's physical, psychosocial and relational care needs is missing.

IMPACT

The population is growing older, and more people are needing more complex hospital care. Frail older people have an increased risk of negative outcomes. The use of a variety of assessment instruments for frailty may pose a challenge to equal care. To ensure a holistic, person-centred view of frail older people, the Fundamentals of Care framework can be used in developing and reviewing practice guidelines.

PATIENT OR PUBLIC CONTRIBUTION

Clinicians and non-health professionals were invited to review the survey to ensure face and content validity.

Healthcare utilization among pre-frail and frail Puerto Ricans

Frailty is associated with adverse health outcomes and greater healthcare utilization. Less is known about the relationship between frailty and healthcare utilization in Puerto Rico, where high rates of chronic conditions and limited healthcare may put this group at a higher likelihood of using healthcare resources. This study examined the association between pre-frailty and frailty with healthcare utilization at baseline and 4-year follow-up among a cohort of community dwelling Puerto Ricans living on the island. We examined data from 3,040 Puerto Ricans (mean age 70.6 years) from The Puerto Rican Elderly: Health Conditions (PREHCO) study between 2002-2003 and 2006-2007. We used a modified version of the Fried criteria defined as 3 or more of the following: shrinking, weakness, poor energy, slowness, and low physical activity. Pre-frailty was defined as 1-2 components. The number of emergency room visits, hospital stays, and doctor visits within the last year were self-reported. Zero-inflated negative binomial regression models were used for ER visits and hospital stays. Negative binomial models were used for doctor visits. Pre-frailty was associated with a higher rate of doctor visits with a rate ratio of 1.11 (95% CI = 1.01-1.22) at baseline. Frailty was associated with a higher rate of ER visits (1.48, 95% CI = 1.13-1.95), hospital stays (1.69, 95% CI = 1.08-2.65), and doctor visits (1.24, 95% CI = 1.10-1.39) at baseline. Pre-frailty and frailty were not associated with any healthcare outcomes at follow-up. Pre-frailty and frailty are associated with an increased rate of healthcare services cross-sectionally among Puerto Rican adults, which may cause additional burdens on the already pressured healthcare infrastructure on the island.

Frailty in community-dwelling older adults: reliability and validity of the Turkish version of the Gérontopôle frailty screening tool

BACKGROUND

Recognizing frailty had a great importance in countries with an increasing geriatric population. The study aims to evaluate the reliability and validation of the Gérontopôle frailty screening tool (GFST), which was developed to screen frailty in the community-dwelling older adults, for the Turkish population.

METHODS

In this crosssectional study, participants who applied to the geriatrics outpatient clinic of a university hospital were included. Comprehensive geriatric assessments of all patients were performed. The validity of the GFST was tested by its concordance with the FRAIL scale. Test-retest and interrater reliability analyses were made.

RESULTS

Ninety-six patients were included in the study. Sixty-one and five-tenths percent (n = 59) of them are females. The median age was 72.0 (IQR: 10.0). There was a moderate concordance between the GFST and the FRAIL scale (Cohen's kappa: 0.566, p < 0.001). The Gérontopôle frailty screening tool interrater and retest reliabilities were excellent (Cohen's kappa: 0.814, p < 0.001 and 1.0, p < 0.001; respectively). The sensitivity of the GFST determined according to the FRAIL scale is 69.39%, the specificity is 86.36%, the positive predictive value is 85.00%, and the negative predictive value is 71.70%.

DISCUSSION

The Gérontopôle frailty screening tool, which can be used by all healthcare professionals, is a valid and reliable tool for the Turkish geriatric population.

Patterns of Muscle-Related Risk Factors for Sarcopenia in Older Mexican Women

Early detriment in the muscle mass quantity, quality, and functionality, determined by calf circumference (CC), phase angle (PA), gait time (GT), and grip strength (GSt), may be considered a risk factor for sarcopenia. Patterns derived from these parameters could timely identify an early stage of this disease. Thus, the present work aims to identify those patterns of muscle-related parameters and their association with sarcopenia in a cohort of older Mexican women with neural network analysis. Methods: Information from the functional decline patterns at the end of life, related factors, and associated costs study was used. A self-organizing map was used to analyze the information. A SOM is an unsupervised machine learning technique that projects input variables on a low-dimensional hexagonal grid that can be effectively utilized to visualize and explore properties of the data allowing to cluster individuals with similar age, GT, GSt, CC, and PA. An unadjusted logistic regression model assessed the probability of having sarcopenia given a particular cluster. Results: 250 women were evaluated. Mean age was 68.54 ± 5.99, sarcopenia was present in 31 (12.4%). Clusters 1 and 2 had similar GT, GSt, and CC values. Moreover, in cluster 1, women were older with higher PA values (p < 0.001). From cluster 3 upward, there is a trend of worse scores for every variable. Moreover, 100% of the participants in cluster 6 have sarcopenia (p < 0.001). Women in clusters 4 and 5 were 19.29 and 90 respectively, times more likely to develop sarcopenia than those from cluster 2 (p < 0.01). Conclusions: The joint use of age, GSt, GT, CC, and PA is strongly associated with the probability women have of presenting sarcopenia.

Effects of frailty on postoperative clinical outcomes of aneurysmal subarachnoid hemorrhage: results from the National Inpatient Sample database

Background

This study aimed to investigate the potential effect of preoperative frailty on postoperative clinical outcomes of patients with aneurysmal subarachnoid hemorrhage (aSAH).

Methods

Data of patients aged 18 years and older who were diagnosed with subarachnoid hemorrhage or intracerebral hemorrhage, underwent aneurysm repair surgical intervention from 2005 to 2014. A retrospective database analysis was performed based on U.S. National Inpatient Sample (NIS) from 2005 to 2014. Frailty was determined using the Johns Hopkins Adjusted Clinical Groups (ACG) frailty-defining diagnoses indicator. Patients were stratified into frail and non-frail groups and the study endpoints were incidence of postoperative complications and related adverse clinical outcomes.

Results

Among 20,527 included aSAH patients, 2303 (11.2%) were frail and 18,224 (88.8%) were non-frail. Significant differences were found between frailty and non-frailty groups in the four clinical outcomes (all p < 0.05). Multivariate analysis showed that frailty was associated with significant higher risks of discharge to institutional care (aOR: 2.50, 95%CI: 2.10–2.97), tracheostomy or gastrostomy tube replacement (aOR: 4.41, 95%CI: 3.81–5.10) and postoperative complications (aOR: 3.29, 95%CI: 2.55–4.25) but a lower risk of death in hospital (aOR: 0.40, 95%CI: 0.33–0.49) as compared with non-frailty. Stratified analysis showed the impact of frailty on some of the outcomes were greater among patients younger than 65 years than their older counterparts.

Conclusions

Frailty is significantly correlated with the increased risk of discharge to institutional care, tracheostomy or gastrostomy tube placement, and postoperative complications but with the reduced risk of in-hospital mortality outcomes after aneurysm repair. Frailty seems to have greater impact among younger adults than older ones. Baseline frailty evaluation could be applied to risk stratification for aSAH patients who were undergoing surgery.

Validity and reliability of the Thai version of the simple frailty questionnaire (T-FRAIL) with modifications to improve its diagnostic properties in the preoperative setting

Background

Several methods are available for identifying frailty, but limited tools have been validated in Thai context. Our objective was to evaluate the validity and reliability of the Thai version of the Simple Frailty Questionnaire (T- FRAIL) compared to the Thai Frailty Index (TFI) and to explore modifications to improve its diagnostic properties.

Methods

The T-FRAIL was translated with permission using a standardized protocol, that included forward and back-translation. Content validity analysis was performed using input from 5 geriatricians. Test-retest reliability, concurrent validity, diagnostic properties, and options to increase the sensitivity of the questionnaire were explored. A cross-sectional study for evaluation validity and reliability was carried out among 3 hundred patients aged 60 or more undergoing elective surgery at a university hospital.

Results

The item content validity index (I-CVI) showed 1.0 for each questionnaire item. Test-retest reliability within a 7-day interval was done in 30 patients with a good intraclass correlation coefficient of 0.880. Compared with the TFI, the T-FRAIL yielded an excellent accuracy (area under the curve = 0.882). The identification of frailty using a score of 2 points or more provided the best Youden’s index at 63.1 with a sensitivity of 77.5% (95% CI 69.0–84.6) and a specificity of 85.6% (95% CI 79.6–90.3). A cutoff point of 1 out of 5 items for original T-FRAIL provided a sensitivity of 93.3% and a specificity of 61.1%. The modified T-FRAIL (T-FRAIL_M1), by reducing the “illnesses” criterion to 4 or more diseases, at a cutoff point at 1 had a sensitivity of 94.2% and a specificity of 57.8%. Another modified T-FRAIL (T-FRAIL_M2), by combining three components, at a cutoff point at 1 yielded a sensitivity of 85.8% and a specificity of 80.6%.

Conclusion

The T-FRAIL and its modification demonstrated satisfactory validity and reliability to identify frailty in elderly patients. The cutoff score of 1 point from 5 items from the original version of T-FRAIL and T-FRAIL_M1 provides a highly sensitive screening tool. T-FRAIL_M1 with a cutoff point of 2 and T-FRAIL_M2 yields reasonable sensitivity and specificity for practical use.

Oral Health as a Predictor of Physical Frailty among Rural Community-Dwelling Elderly in an Agricultural County of Taiwan: A Cross-Sectional Study

We conducted a cross-sectional study to clarify the relationship between oral health and physical frailty (PF). A sample of 903 community-dwelling individuals aged ≥ 65 years were enrolled from random communities in Chiayi County. The self-perceived oral health (SPOH) and oral health assessment tool (OHAT), which consists of eight items, was used for the evaluation of their oral health status. PF was assessed based on the Study of Osteoporotic Fracture index. Overall, 14.6% of the participants had PF. In an adjusted model, restricted food types (odds ratio (OR) = 1.59, 95% confidence interval (CI): 1.2–2.09, p = 0.001), self-reported dental status (OR = 1.61, 95% CI: 1.2–2.15, p = 0.001), number of teeth (OR = 0.98, 95% CI: 0.96–0.99, p = 0.006), frequency of tooth cleaning (OR = 0.83, 95% CI: 0.68–1.0, p = 0.049), OHAT score (OR = 1.09, 95% CI: 1.02–1.17, p < 0.017), and saliva items of OHAT (OR = 1.52, 95% CI: 1.11–2.1, p = 0.010) were significantly associated with PF. SPOH is a crucial indicator of PF; longitudinal analyses are necessary to understand the underlying pathway of risk factors for frailty onset.

Effects of carbonation of liquids on penetration-aspiration and residue management

Objective

Carbonation as a sensory enhancement strategy for prevention of aspiration of thin liquids has not been thoroughly studied. The aim of our study was to examine the effect of carbonation on penetration–aspiration and pharyngeal residue in dysphagia patients using Fiber-Optic Endoscopic Evaluation of Swallowing (FEES) and to identify parameters associated with a response to carbonation.

Methods

A cross-sectional study of patients undergoing FEES in a dysphagia clinic. Patients were offered 100 cc of dyed water. Penetration–aspiration was scored using the penetration–aspiration scale (PAS). Residue was scored using the Yale Pharyngeal Residue Severity Rating Scale (YPR-SRS). Patients with a PAS ≥ 2 for water were subsequently offered 100 cc of carbonated water. PAS, YPR-SRS and residue clearance were compared between thin and carbonated liquids. Multivariate logistic regression analysis was used to identify predictors for good response to carbonation.

Results

84 patients were enrolled, 77.4% males, with diverse dysphagia etiologies (58.3% neurogenic, 11.9% radiation-induced, 23.8% deconditioning-induced, and 6% neck surgery induced). Median PAS was 7 (IQR 4–8) for thin liquids and 4.5 (IQR 2–8) for carbonated liquids (P = 0.0001). YPR-SRS was reduced for carbonated compared to thin liquids in the vallecula (1.58 ± 0.83 vs 1.76 ± 0.93, P = 0.001) and piriform sinuses (1.5 ± 0.87 vs 1.67 ± 0.9, P = 0.002). 31 patients had improvement in PAS with carbonation. Deconditioning as a dysphagia etiology was found to predict good response to carbonation on multivariate logistic regression analysis.

Conclusion

Carbonation may prevent aspiration and improve residue management for some patients with dysphagia for liquids.

Oral health condition and development of frailty over a 12-month period in community-dwelling older adults

Background

To determine the association between oral health condition and development of frailty over a 12-month period in community-dwelling older adults.

Methods

Population-based, case-cohort study derived from the Cohort of Obesity, Sarcopenia, and Frailty of Older Mexican Adults (COSFOMA) study, including data from years 2015 and 2016. Using latent class analysis, we determined the oral health condition of older adults with teeth (t₀), i.e., functional teeth, presence of coronal caries, root caries, periodontal disease, dental calculus, dental biofilm, root remains, xerostomia, and need for dental prosthesis. Edentulous was considered as a separate class. Criteria of the Frailty Phenotype (t₁) by Fried et al. were used: weight loss, self-report of exhaustion, walking speed, decreased muscle strength, and low physical activity. The presence of three or more criteria indicated a frail condition. The strength of the association (odds ratio, OR) between oral health condition and development of frailty was estimated through bivariate analysis. Multiple logistic regression was used to adjust for the other variables of study: sociodemographic data (sex, age, marital status, level of education, paid work activity, and living alone), comorbidities, cognitive impairment, depressive symptoms, nutritional status, and use of oral health services.

Results

663 non-frail older adults were evaluated, with a mean age of 68.1 years (SD ± 6.1), of whom 55.7% were women. In t₀, a three-class model with an acceptable value was obtained (entropy = 0.796). The study participants were classified as: edentulous persons (6.9%); Class 1 = Acceptable oral health (57.9%); Class 2 = Somewhat acceptable oral health (13.9%); and Class 3 = Poor oral health (21.3%). In t₁, 18.0% (n = 97) of participants developed frailty. Using Acceptable oral health (Class 1) as a reference, we observed that older adults with edentulism (OR 4.1, OR adjusted 2.3) and Poor oral health (OR 2.4, OR adjusted 2.2) were at an increased risk of developing frailty compared to those with Acceptable oral health.

Conclusion

Older adults with edentulism and poor oral health had an increased risk of developing frailty over a 12-month period.

Association of Frailty Status and Functional Disability among Community-Dwelling People Aged 80 and Older in Vietnam

Objectives

This study investigated associations between frailty and functional disability in elder suburban Vietnamese.

Method

Cross-sectional analysis was carried out on 251 participants aged 80 and over in Soc Son district. We used the Instrumental Activities of Daily Living (IADL) scale including 8 items, and functional disability was defined as ≥3 IADL impairment. We defined frail as ≥3 out of 5 frailty components including weight loss > 5%, weak grip, exhaustion, low walking speed, and low physical activity.

Results

Of 251 participants with a mean age of 84.6, 11.2% was classified as frail and 64.5% had ≥3 IADLs. Among the frailty components, low walking speed and low physical activity were significantly associated with increased odds of having ≥3 IADLs: ORs (95% CI) were 4.2 (2.3-7.9) and 3.7 (1.7-8.2).

Conclusion

Frailty is associated with the higher likelihood of having functional disability. Further longitudinal studies are needed to examine the causal this relationship.

Factors Associated With Frailty in Patients Undergoing Cardiac Surgery: A Longitudinal Study

BACKGROUND

Frailty may increase the risk of complications and mortality in patients undergoing cardiac surgery. Few studies on frailty and its associated factors have been conducted in these patients.

OBJECTIVE

The aim of this study was to explore frailty and related factors in patients undergoing cardiac surgery.

METHODS

A total of 154 patients undergoing cardiac surgery in northern Taiwan were recruited using a longitudinal study design and interviewed using structured questionnaires assessing physical activity, anxiety and depression, and social support before surgery and at 1 month and 3 months after surgery.

RESULTS

The prevalence of frailty in patients undergoing cardiac surgery was 16.2%, 20.5%, and 16.6% before surgery and at 1 month and 3 months after surgery, respectively. Frail and prefrail patients undergoing cardiac surgery were more likely to be unemployed, have gout, have a higher New York Heart Association class, have preoperative dysrhythmia, undergo cardiopulmonary bypass, have a lower functional ability, have a higher European System for Cardiac Operative Risk Evaluation score, have a longer anesthesia time, have longer endotracheal tube and extracorporeal circulation times, have longer intensive care unit and hospital stays, have lower hemoglobin and albumin levels, have higher anxiety and depression levels, and have lower Mini-Mental State Examination scores. The significant predictors of prefrailty and frailty included unemployment, the presence of gout, higher New York Heart Association classes, less independence in activities of daily living, lower hemoglobin levels, and higher levels of depression.

CONCLUSIONS

Frailty was associated with patients' functional status, perioperative conditions and psychosocial factors. Preoperative assessments of frailty and appropriate interventions are needed to improve frailty in patients undergoing cardiac surgery.

Association between Phthalate Exposure and Frailty among Community-Dwelling Older Adults: A Repeated Panel Data Study

Only a few studies have examined the impacts of environmental exposure on frailty. This study investigated the association between phthalates and frailty among community-dwelling older adults. The Korean Elderly Environmental Panel II (KEEP II) study is a repeated panel data study of 800 community-dwelling older adults in South Korea. Frailty was measured with five items defined by Fried and colleagues. Environmental pollutants in the form of two types of metabolites for Di-ethylhexyl phthalate (DEHPs)-Mono (2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) and Mono (2-ethyl-5-oxohexyl) phthalate (MEOHP)-were obtained from urine specimens. Analyses were performed using repeated linear mixed models. The concentration levels of both MEOHP and MEHHP in urine were significantly higher in the pre-frail or frail group than its counterparts. While adjusting for covariates, MEOHP level was positively associated with the likelihood of being pre-frail or frail in both males and females; the concentration level of MEHHP also had a positive impact on the likelihood of being pre-frail or frail in females. The DEHP metabolite concentrations were significantly lower among adults with daily fruit consumption in both males and females. DEHPs, measured by metabolite concentrations, may increase the risk of frailty among older men and women; further studies are necessary. The preventive effects of nutrition on DEHP risk should also be further investigated.

Factors associated with the risk of violence against older adult women: a cross-sectional study

Objective:

to identify the factors associated with the risk of violence against older adult women.

Method:

this is a quantitative, analytical, and cross-sectional research conducted with 122 older adult females in the city of Recife, state of Pernambuco, Brazil. Data collection was carried out using validated instruments adapted to Brazil. The analysis was performed using descriptive statistics (absolute and relative frequency) and inferential statistics (Pearson’s chi- square, Spearman’s correlation test, and Multiple Logistic Regression).

Results:

there was prevalence of a risk of abuse against older adult women under 70 years of age, literate, without a stable relationship, living alone, without any work activity, and who had an income higher than the minimum wage. There is a significant association between the risk of violence among older women with a higher number of chronic health conditions (24; 77.4%), and who are less active in advanced activities (42; 70.0%). A reduction in quality of life and satisfaction with life, and the onset of depressive symptoms, increase the risk of violence.

Conclusion:

multimorbidity, low functional capacity, depressive symptoms, low quality of life and low satisfaction with life, a high number of chronic conditions, depressive symptoms, and functional dependence to perform daily activities can be conditioning factors for the emergence of abuse against older adults.

Sex Differences in the Association Between Risk of Obstructive Sleep Apnea, Insomnia, and Frailty in Older Adults

PURPOSE

To analyze the association between risk of obstructive sleep apnea (OSA), insomnia, sleepiness and self-assessed sleep duration with frailty in older adults.

PATIENTS AND METHODS

Cross-sectional study with 1643 older adults (60 to 97 years old) who participated in round 6 (2019) of the Cohort of Obesity Sarcopenia and Obesity in Older Adults of the Mexican Institute of Social Security. The Berlin Questionnaire was used to assess risk of OSA, the Athens Insomnia Scale for insomnia, the Epworth Scale for sleepiness, and sleep duration by self-report. Frailty was assessed with the frailty criteria proposed by Fried. Sociodemographic and health variables were also collected. Statistical analysis was performed with logistic regression and was stratified by sex.

RESULTS

This study included 1643 participants (823 men and 820 women). Mean age was 67.1 ± 5.9 years. The percentage of frail older adults was 10.5% (n = 172), with risk of OSA 26.1% (n = 429), with insomnia 30.3% (n = 497) and with sleepiness 18.9% (n = 310). In all participants, risk of OSA and insomnia were associated with frailty. In the stratified analysis by sex, the association between risk of OSA and frailty was observed in women (odds ratio (OR) = 1.84, 95% confidence interval (CI) 1.05, 3.22), but not in men (OR = 1.19, 95% CI: 0.65, 2.19). Insomnia was significantly associated with frailty in women (OR = 2.38, 95% CI: 1.35, 4.20) and in men (OR = 1.88, 95% CI: 1.01, 3.52). Neither sleepiness nor sleep duration was associated with frailty.

CONCLUSION

In community-dwelling older adults, both the risk of OSA and insomnia conferred greater odds of presenting frailty in women. It is required to implement strategies aimed at improving sleep hygiene and detecting patients with OSA and insomnia.

Factors associated with frailty transition at different follow-up intervals: A scoping review

Frailty is a dynamic process. Identifying the factors associated with frailty transition may increase the opportunities for success in interventions for frailty. This scoping review, following Arksey and O'Malley's methodological framework, aimed to identify the factors associated with frailty transition and the rate of frailty transition among community-dwelling older people. A literature search was conducted. Among the included studies, 5, 13, and 3 involved follow-up intervals of 2-3 years (short term), 4-6 years (intermediate term), and >6 years (long term), respectively. Reportedly, life course characteristics, diseases, and psychological factors were related to frailty transitions at all follow-up intervals. Physical factors were related to frailty transition at both short and intermediate follow-up intervals, while social factors were related to frailty transition at intermediate follow-up intervals. The rate of improvement in frailty seemed to decrease, and that of worsening seemed to increase when the follow-up intervals lengthened.

Social isolation undermines quality of life in older adults

OBJECTIVE

Several studies have documented associations between social isolation and poor physical health or well-being. However, little is known of the importance of social support among older adults on specific topics about their quality of life. The purpose of the present study was to determine the relationship between social isolation and quality of life among older adults.

DESIGN

A cross-sectional study.

SETTING

Mexico City.

PARTICIPANTS

1,252 subjects aged ≥ 60 years living at home.

MEASUREMENTS

We used the Abbreviated Version of the Lubben Social Network Scale (LSNS-6) to assess social isolation and the World Health Organization Quality of Life Instrument-Older Adults Module (WHOQOL-Old) to assess quality of life. Socio-demographic and health factors were collected through face-to-face interviews. A series of linear regression analyses were used to investigate relationship between social isolation and quality of life. The statistical models were controlled for socio-demographic and health factors.

RESULTS

A total of 750 women (60%) and 502 men (40%) participated in the study. According to their LSNS-6 scores, 426 participants (34.0%) were classified into the highest group of isolation (range 0-10 points). Older adults with higher scores of social isolation exhibited lower quality of life. Regression analyses indicated that social isolation correlated with lower levels of global quality of life, autonomy, intimacy, and past, present, and future activities.

CONCLUSIONS

Coping with life from a socially isolated situation entails serious difficulties concerning quality of life. Interventions that foster environments where older adults can forge social bonds might improve their quality of life.

Interpopulation Similarity of Sex and Age-Related Body Composition Variations Among Older Adults

The aim of the study was to analyze sex and age-related body composition variations among older adults from the Brazilian, Italian, and Mexican population. A cross-sectional analysis was conducted in 1103 community-dwelling older adults (634 women and 469 men), aged 60 to 89 years, living in Brazil (n = 176), Italy (n = 554), and Mexico (n = 373). Anthropometric measurements were taken, BMI was calculated, and impedance measurements were obtained (resistance, R, reactance, Xc). Specific bioelectrical impedance vector analysis (specific BIVA) was applied, with the specific vector defined by impedance, or vector length (Z = (Rsp² + Xcsp)^0.5), and phase angle (PA = arctan Xc/R 180/π). Population, sex, and age differences in anthropometric and bioelectrical variables were evaluated by means of a two way ANOVA. The mean bioelectrical vectors were graphed by confidence ellipses and statistically compared by the Hotelling's T² test. The three population groups showed differences in body mass and composition (p < 0.001): the Brazilian sample was characterized by greater body dimensions, longer vectors (higher relative content of fat mass), and lower phase angles (lower skeletal muscle mass). Men were taller and heavier than women (p < 0.001) but had a similar BMI (p = 0.102). They also had higher phase angle (higher skeletal muscle mass) (p < 0.001) and lower vector length (lower %FM) (p < 0.001). In the three population groups, the oldest individuals showed lower anthropometric and phase angle values with respect to the youngest ones (p < 0.001), whereas the vector length did not change significantly with age (p = 0.665). Despite the differences between sexes and among populations, the trend of age-related variations was similar in the Brazilian, Italian, and Mexican older adults.

Differences in the predictive capability for functional impairment, cognitive decline and mortality of different frailty tools: A longitudinal cohort study

BACKGROUND AND OBJECTIVES

There are multiple frailty detection tools, but they have not been specifically developed for the institutionalised population. The aim of this study is to ascertain at 3-year follow-up which tool predicts functional impairment and mortality most precisely.

METHODS

Longitudinal cohort study with 110 patients in Pamplona (Navarra)>65 years. Four frailty tools were applied (Fried Criteria, Rockwood Frailty Scale, FRAIL-NH and Imputed Fried Frailty Criteria). The power of the association between the scales and the results was assessed by linear regression and Cox's analyses.

RESULTS

46.5% of the sample died during time to follow-up, 68% of whom died in their nursing home, with 43-month mean survival. Of the studied population, 71.3% showed disability at 3 years, especially the frail subjects. The robust patients had longer hospitalizations (m=3.4 days) than the frail. Imputed Fried and FRAIL-NH found statistically significant differences between groups for the variables studied. Imputed Fried Frailty Criteria showed a significant HR of death for the frail subjects (HR=3.3).

CONCLUSIONS

The Imputed Fried and FRAIL-NH tools showed a higher predictive capability for functional and cognitive decline, but only the Imputed Fried Frailty Criteria found a significant relationship between frailty and mortality.

Is living alone a risk factor of frailty? A systematic review and meta-analysis

OBJECTIVES

To examine the association of living alone with frailty in cross-sectional and longitudinal studies by a systematic review and meta-analysis.

DESIGN

Systematic review and meta-analysis.

SETTING AND PARTICIPANTS

Community-dwelling older adults with a mean age of >60 years.

METHODS

A systematic search of the literature was conducted according to the PRISMA guidelines. We searched PubMed in February 2019 without language restriction for cohort studies that examined the associations between living alone and frailty. The reference lists of the relevant articles and the included articles were reviewed for additional studies. We calculated pooled odds ratios (OR) of the presence and incidence of frailty for living alone from cross-sectional and longitudinal studies.

RESULTS

Among the 203 studies identified, data of 44 cross-sectional studies (46 cohorts) and 6 longitudinal studies were included in this review. The meta-analysis showed that older adults living alone were more likely to be frail than those who were not (46 cohorts: pooled OR = 1.28, 95 % confidence interval (CI) = 1.13-1.45, p < 0.001). Gender-stratified analysis showed that only men living alone were at an increased risk of being frail (20 cohorts: pooled OR = 1.71, 95 %CI = 1.49-1.96), while women were not (22 cohorts: pooled OR = 1.00, 95 %CI = 0.83-1.20). No significant association was observed in a meta-analysis of longitudinal studies (6 cohorts: pooled OR = 0.88, 95 %CI = 0.76-1.03).

CONCLUSIONS/IMPLICATIONS

The present systematic review and meta-analysis showed a significant cross-sectional association between living alone and frailty, especially in men. However, living alone did not predict incident frailty. More studies controlling for important confounders, such as social networks, are needed to further enhance our understanding of how living alone is associated with frailty among older adults.

Insomnia, low sleep quality, and sleeping little are associated with frailty in Mexican women

OBJECTIVE

To analyze the influence that sex has on the association between insomnia, sleep quality, sleep duration, and frailty in older adults.

SUBJECTS & METHODS

Cross sectional study from the Cohort Obesity, Sarcopenia, and Frailty in Older Mexican Adults (COSFOMA). In total, 493 older adults aged 64-94 participated. Insomnia was evaluated with the Athens Insomnia Scale and sleep quality with the Pittsburgh Sleep Quality Index. Duration of sleep was classified as short (<5 h and 5-6 hours), recommended (7-8 hours), and long (≥ 9 h). Frailty was operationalized with the Fried phenotype. Furthermore, sociodemographic variables were collected, along with physical and mental health. Logistic regression models were stratified by sex to analyze the relationship between insomnia, sleep quality, sleep duration, and frailty.

RESULTS

Participants included 299 (60.7 %) women and 194 (39.3 %) men. The average age was 70.1 ± 5.6 years. Frail older adults comprised 13.4 % of the sample (n = 66), while 62.5 %(n = 308) were pre-frail and 24.1 % were not frail (n = 119). In the statistical models adjusted for sociodemographic and health covariates, insomnia, low sleep quality, and sleeping less than five hours were shown to increase the odds of being frail in women, but not in men.

CONCLUSION

In older adult women, the presence of insomnia, low sleep quality, and sleeping less than five hours could promote frailty. Therefore, treatment of sleep problems among women should be prioritized to avoid the onset of this condition.

Prevalence and Associated Factors of Frailty in Community-Dwelling Older Adults in Indonesia, 2014-2015

Objective: The investigation aims to study the prevalence and correlates of frailty in a national community-dwelling sample of older Indonesians. Methods: Participants were 2630 older adults, 60 years and older (median age 66.0 years, interquartile range = 9.0) who took part in the cross-sectional Indonesia Family Life Survey (IFLS-5) in 2014–2015. They were requested to provide information about sociodemographic and various health variables, including frailty. Multivariable Poisson regression analysis was utilized to estimate the correlates of socio-demographic factors, health variables, and frailty. Results: The overall prevalence of frailty was 8.1%; 61.6% were prefrail. In adjusted Poisson regression analysis, older age, being unmarried, separated, divorced or widowed, residing in Java and major island groups, poor cognitive functioning, loneliness, and functional disability were associated with frailty. Conclusion: Several sociodemographic and health risk factors for frailty were identified that can help in guiding intervention strategies in Indonesia.

Decreased Autonomy In Community-Dwelling Older Adults

Purpose

The present study aims to explore characteristics associated with low perception of autonomy among community-dwelling older adults.

Patients and methods

This original research was derived from a cross-sectional study based on the study COSFOMA with information from 1,252 (60 years and older) community-dwelling older adults whose data was obtained through a questionnaire that included sociodemographic characteristics, as well as different scales of geriatric assessment. The perception of autonomy was evaluated with the autonomy sub-scale of the Quality of Life Scale of Older Adults from the World Health Organization (World Health Organization Quality of Life of Older Adults, WHOQOL-OLD).

Results

The mean (SD) age of the 1,252 community-dwelling older adults participating in the study was 68.5 (7.2) years. The average perception of autonomy was 65.3 (18.2) points out of 100. In the final logistic regression model, schooling <6 years (Odds Ratio, OR = 2.1, 95% Confidence Interval, CI = 1.5-2.9), low social support (OR = 1.6, 1.2-2.2), low spirituality (OR = 2.6, 95% CI = 1.9-3.4), presence of cognitive impairment (OR = 1.9, 95% CI = 1.4-2.5), anxiety (OR = 1.7, 95% CI = 1.2-2.5), and limitation in activities of daily living (ADL) (OR = 1.6, 95% CI = 1.1-2.2) were statistically associated with the presence of low autonomy in older adults.

Conclusion

The perception of autonomy among community-dwelling older adults is moderate. Social support and spirituality, as well as cognitive impairment, anxiety, and limitations in ADL, play a significant role for degree of perceived autonomy in this population. Health professionals can use this information to promote participation in decision-making processes through programs that improve quality of life.

Marital Status and Risk of Physical Frailty: A Systematic Review and Meta-analysis

OBJECTIVES

Evidence on associations between marital status and frailty is limited. The objectives of this study were to perform a systematic review for associations between marital status and physical frailty and to perform a meta-analysis to combine findings.

DESIGN

Systematic review and meta-analysis.

SETTING AND PARTICIPANTS

Community-dwelling older people with mean age ≥60 years.

METHODS

Systematic literature search using 5 databases was conducted in February 2019 to identify longitudinal and cross-sectional studies examining associations between marital status and Fried's phenotype-based frailty status. Additional studies were searched for by reviewing the reference lists of relevant articles and conducting forward citation tracking of included articles. Odds ratio (OR) of marital status and frailty was pooled using a random-effects meta-analysis. Subgroup analysis and analyses stratified by gender and marital status (married, widowed, divorced or separated, and never married) were completed.

RESULTS

A total of 1565 studies were found, from which 3 studies with longitudinal data and 35 studies with cross-sectional data were included. Although longitudinal studies suggested that married men had lower frailty risks than unmarried men while married women had higher frailty risks than widowed women, meta-analysis was not possible because of different methodologies. Meta-analyses of cross-sectional data from 35 studies including 80,754 individuals showed that unmarried individuals were almost twice more likely to be frail than married individuals (pooled odds ratio = 1.88, 95% confidence interval = 1.70-2.07). A high degree of heterogeneity was observed (I² = 69%) and was partially explained by reasons for not being married and study location. Stratified analyses showed that pooled risks of frailty in the unmarried compared with the married were not statistically different between women and women (P for difference = .62).

CONCLUSIONS AND IMPLICATIONS

Three and 35 studies, respectively, were found providing longitudinal and cross-sectional data regarding associations between marital status and frailty among community-dwelling older people. A meta-analysis of cross-sectional data showed almost twice higher frailty risk in unmarried individuals compared with married individuals. Marital status should be recognized as an important factor, and more longitudinal studies controlling for potential confounding factors are needed.

Frailty as the basis for physiotherapeutic procedures for 65+ patients

Introduction: The frailty syndrome (FS) is a syndrome of functional limitations related to the older age, and its specificity, as well as the scale of occurrence, justify the need for its description and ordering of knowledge in this area. Aim: The aim of the literature review is to systematize knowledge in the field of individual descriptive elements of FS and rehabilitation dedicated to FS. Material and metods: The publication is a review and systematizes research material in the field of syndrome frailty. The narrative review was based on the analysis of publications contained in the Pubmed database in the period 2012-2017 and Polish sources published in this period. The sources were selected in accordance with the purpose of the work. Results: The frailty syndrome is defined and defined in various ways, although the main reference refers to its first description, formulated by L. Fried et al. There are three main phenotypes of the weakness group, classified based on the criteria of the creators of this team. Different scales are used in diagnostics: CHS, FRAIL, ESF, as well as GFI, TFI and PLFI indicators. The frailty syndrome develops based on the causes and effects of the so-called a cascade of weaknesses, among them chronic inflammatory processes, sarcopenia and immunological changes are of key importance. Recommended physiotherapy regimens cover various cycles and types of physical activity, with the use of a 12-week program of exercises of various types most often emphasized. Conclusions: Frailty is a state of exhaustion of reserves and functional limitations of the older age, also referred to as a team of weakness, frailty and fragility. Most reports confirm the use and usefulness of the CHS scale. Lack of unambiguous physiotherapy regimens for FS.

Prevalence of falls and associated factors in community-dwelling older Brazilians: a systematic review and meta-analysis

Falls determine huge epidemiological, clinical, and economic burden in the older population worldwide, presenting high odds of severe disability. The present study aimed to estimate the prevalence of falls and associated factors in older Brazilians using a systematic review with meta-analysis. Searches were performed in SciELO, PubMed, LILACS, Web of Science, Scopus and PsycINFO databases with no date or language restrictions. Studies on community-dwelling older persons aged ≥ 60 years from both sexes and with a sample size of ≥ 300 participants included. Exclusion criteria were studies conducted specifically for older adults diagnosed with chronic disabling diseases that predispose them to falls. Risk of bias of included studies was assessed using a critical appraisal tool focusing on prevalence designs. A random-effects meta-analysis was used to pool the prevalence of falls across studies. Exploratory analysis was conducted examining subgroup estimates, prevalence ratios and meta-regression. Thirty-seven studies involving 58,597 participants were included. Twelve-month prevalence of falls was 27% (95%CI: 24.3-30.0), with significantly higher estimates in female than male (PR = 1.57; 95%CI: 1.32-1.86), in age group ≥ 80 years than age group 60-69 years (PR = 1.46; 95%CI: 1.15-1.84), and in participants from the Central region than participants from the South region (PR = 1.36; 95%CI: 1.10-1.69) of Brazil. Risk of bias scores did not impact heterogeneity in the 12-month meta-analysis. These estimates strongly support evidence-based public interventions to prevent falls in older Brazilians, especially in women and the oldest-old population.

Potentially inappropriate prescribing to older adults in ambulatory care: prevalence and associated patient conditions

PURPOSE

To analyze potentially inappropriate prescribing (PIP), its prevalence and patient conditions associated with this phenomenon, in a cohort of older adults receiving outpatient care in Mexico.

METHODS

Data from 1252 adults ≥ 60 years of age, from primary care centers were analyzed. Information included sociodemographic data, medications, chronic diseases, polypharmacy (≥ 5 medications), functional dependence, cognitive impairment and frailty. Three logistic regression models were employed to identify associations between PIP (according to the Beers criteria) and different variable combinations.

RESULTS

A total of 41.8% of participants had at least one PIP. The most frequently identified PIPs involved nonsteroidal anti-inflammatory drugs (NSAIDs) and glibenclamide; clonazepam in patients with cognitive impairment; and interactions of warfarin with NSAIDs. In the multivariate analyses, Model 1 showed that frailty and polypharmacy were associated with PIP. In Model 2, only polypharmacy was associated with PIP. For Model 3, lower educational levels, taking hypoglycemics, nervous system disease drugs, antiasthmatics, gastrointestinal disease drugs and anti-inflammatories-antirheumatics and analgesics, were associated with PIP.

CONCLUSION

PIP is common in outpatient treatment of health care services in Mexico. Its association with medical and nonmedical factors highlights the need to improve drug treatment quality focused on implementation of effective strategies, such as educative interventions, electronic medication safety alerts, and inclusion of pharmacists in the health team.

Effect of a multicomponent exercise programme (VIVIFRAIL) on functional capacity in frail community elders with cognitive decline: study protocol for a randomized multicentre control trial

BACKGROUND

The benefit of physical exercise in ageing and particularly in frailty has been the aim of recent research. Moreover, physical activity in the elderly is associated with a decreased risk of mortality, of common chronic illnesses (i.e. cardiovascular disease or osteoarthritis) and of institutionalization as well as with a delay in functional decline. Additionally, very recent research has shown that, despite its limitations, physical exercise is associated with a reduced risk of dementia, Alzheimer disease or mild cognitive decline. Nevertheless, the effect of physical exercise as a systematic, structured and repetitive type of physical activity, in the reduction of risk of cognitive decline in the elderly, is not very clear. The purpose of this study aims to examine whether an innovative multicomponent exercise programme called VIVIFRAIL has benefits for functional and cognitive status among pre-frail/frail patients with mild cognitive impairment or dementia.

METHODS/DESIGN

This study is a multicentre randomized clinical trial to be conducted in the outpatient geriatrics clinics of three tertiary hospitals in Spain. Altogether, 240 patients aged 75 years or older being capable of and willing to provide informed consent, with a Barthel Index ≥ 60 and mild cognitive impairment or mild dementia, pre-frail or frail and having someone to help to supervise them when conducting the exercises will be randomly assigned to the intervention or control group. Participants randomly assigned to the usual care group will receive normal outpatient care, including physical rehabilitation when needed. The VIVIFRAIL multicomponent exercise intervention programme consists of resistance training, gait re-training and balance training, which appear to be the best strategy for improving gait, balance and strength, as well as reducing the rate of falls in older individuals and consequently maintaining their functional capacity during ageing. The primary endpoint is the change in functional capacity, assessed with the Short Physical Performance Battery (1 point as clinically significant). Secondary endpoints are changes in cognitive and mood status, quality of life (EQ-5D), 6-m gait velocity and changes in gait parameters (i.e. gait velocity and gait variability) while performing a dual-task test (verbal and counting), handgrip, maximal strength and power of the lower limbs as well as Barthel Index of independence (5 points as clinically significant) at baseline and at the 1-month and 3-month follow-up.

DISCUSSION

Frailty and cognitive impairment are two very common geriatric syndromes in elderly patients and are frequently related and overlapped. Functional decline and disability are major adverse outcomes of these conditions. Exercise is a potential intervention for both syndromes. If our hypothesis is correct, the relevance of this project is that the results can contribute to understanding that an individualized multicomponent exercise programme (VIVIFRAIL) for frail elderly patients with cognitive impairment is more effective in reducing functional and cognitive impairment than conventional care. Moreover, our study may be able to show that an innovative individualized multicomponent exercise prescription for these high-risk populations is plausible, having at least similar therapeutic effects to other pharmacological and medical prescriptions.

Frailty is associated with myosteatosis in obese patients with colorectal cancer

BACKGROUND & AIMS

We aimed to explore the determinants of muscle fat infiltration and to investigate whether myosteatosis, assessed as muscle fat infiltration percentage (%MFI) and muscle attenuation from computed tomography (CT), is associated with frailty in a group of patients with colorectal cancer (CRC).

METHODS

Cross sectional study including CRC patients. CT scan of the third lumbar vertebra was used to quantify body composition and the degree of %MFI (reported as percentage of fat within muscle area). Frailty was defined by Fried et al. (2001) as the presence of more than 3 criteria: unintentional weight loss, self-reported exhaustion, weakness (low handgrip strength), slow walking speed (gait speed) and low physical activity. Obesity was defined according to sex-and-age-specific body fat percentage (%BF) cutoff.

RESULTS

A sample of 184 patients (age 60 ± 11 years; 58% men; 29% of patients with frailty) was studied. The sample was divided according to tertiles of MFI% (1st tertile 0 to 2.89%, n = 60; 2nd tertile ≥ 3.9-8.19%, n = 64; 3rd tertile ≥ 8.2-26%, n = 60). Age, females, body mass index, %BF, subcutaneous and visceral adipose tissue and the proportion of patients with frailty were significantly higher in the 3rd %MFI tertile. Phase angle and muscle attenuation were significantly lower in the 3rd %MFI tertile. The determinants of %MFI (r² = 0.49), which was log transformed due to its normal distribution, were %BF (β = 0.54; e^β = 1.72; 95% CI: 0.032 to 0.051; P < 0.01), age (β = 0.34; e^β = 1.40; 95% CI: 0.016 to 0.032; P < 0.01) and gait speed (β = -0.12; e^β = 0.87; 95% CI: -0.84 to -0.001; P = 0.049). In addition, in obese patients (n = 74) presenting 4 or 5 frailty criteria increased the chance of having higher %MFI and lower muscle attenuation, after adjustment for sex, age and comorbidities when compared to none or 1 criteria.

CONCLUSIONS

In a sample of CRC patients, %BF and gait speed were the determinants of %MFI. In addition, markers of myostetatosis were associated with frailty in the obese patients.

Mental Illness, Not Obesity Status, is Associated with Food Insecurity Among the Elderly in the Health and Retirement Study

OBJECTIVES

Food insecurity, limited or uncertain access to adequate nutrition, is an increasingly recognized determinant of health outcomes and is often associated with having obesity. It is unclear, however, if this association persists in elderly populations.

METHODS

We conducted a cross-sectional study of 2868 participants' aged 65+ years from the Health and Retirement Study. Multivariate logistic regression was used to assess associations between food insecurity and body mass index, demographic characteristics, psychiatric history, and medical history.

RESULTS

Participants with overweight/obesity had a higher prevalence of food insecurity than leaner counterparts, however, weight status was not a significant predictor of food insecurity after multivariate adjustment. Instead, mental illness, current smoking status, and non-White race were all independently associated with food insecurity.

DISCUSSION

Beyond financial status, health care providers are encouraged to use these characteristics to identify elderly patients that may be at risk of food insecurity.

Frailty in older adults in the city of São Paulo: Prevalence and associated factors

INTRODUCTION

Frailty is a preventable and reversible syndrome characterized by a cumulative decline of physiological systems, causing greater vulnerability to adverse conditions.

OBJECTIVE

To describe the prevalence of frailty among older adults and analyze its associated factors and progression.

METHOD

This is a longitudinal study that used the Health, Well-being, and Aging Study (Saúde, Bem-Estar e Envelhecimento - SABE) database of 2006 and 2010. Five components identified the frailty syndrome: weight loss; fatigue; decreased strength, low physical activity, and reduced walking speed. Older adults were classified as "pre-frail" (1-2 components) and "frail" (3 or more). We used a hierarchical multiple multinomial regression to analyze associated factors.

RESULTS

Out of the total number of older adults (n = 1,399), 8.5% were frail, and the associated factors were age, functional impairment, cognitive decline, hospitalization, and multimorbidity. In four years, 3.3% of non-frail and 14.7% of pre-frail older adults became frail.

CONCLUSION

Identifying the prevalence of frailty and its associated factors can help to implement adequate interventions early to improve the quality of life of older adults.

Frailty and Caenorhabditis elegans as a Benchtop Animal Model for Screening Drugs Including Natural Herbs

Caenorhabditis elegans has been used in research for years to clarify the genetic cascades and molecular mechanisms of aging, longevity, and health span. Health span is closely related to frailty; however, frailty has a different concept and is evaluated using various parameters in humans, such as Fried's Frailty Criteria. The C. elegans model has several advantages when performing a chemical screen to identify drug candidates. Several mouse models of frailty were recently developed, including a homozygous IL-10 knockout. These mouse models are useful for understanding human frailty; however, they are not appropriate for primary drug screening because they require large spaces, expensive cost, and time consuming assessments. Therefore, a combination of these models may be a promising tool for discovering drugs and understanding the mechanisms of frailty. In addition, natural products, and herbs are attractive sources of novel drugs with pharmacological activity and low toxicity, in fact, over 60% of currently-available drugs are estimated to be related to natural compounds. In this review, the possibility of identifying natural agents (i.e., herb extracts and compounds) that could improve frailty are proposed, and the advantages and limitations of these models are also discussed.

Dysphagia Onset in Older Adults during Unrelated Hospital Admission: Quantitative Videofluoroscopic Measures

New-onset swallowing difficulties in older patients during unrelated hospital admissions are well recognized and may result in prolonged hospital stay and increased morbidity. Presbyphagia denotes age-related swallowing changes which do not necessarily result in pathological effects. The trajectory from presbyphagia to dysphagia is not well understood. This retrospective observational study compared quantitative videofluoroscopic measures in hospitalized older adults aged 70-100 years, reporting new dysphagia symptoms during admission (n = 52), to healthy asymptomatic older (n = 56) and younger adults (n = 43). Significant physiological differences seen in hospitalized older adults but not healthy adults, were elevated pharyngeal area (p < 0.001) and pharyngeal constriction ratio (p < 0.001). Significantly increased penetration (p < 0.001), aspiration (p < 0.001) and pharyngeal residue (p < 0.001) were also observed in the hospitalized older cohort. Reasons for onset of new swallow problems during hospitalization are likely multifactorial and complex. Alongside multimorbidity and polypharmacy, a combination of factors during hospitalization, such as fatigue, low levels of alertness, delirium, reduced respiratory support and disuse atrophy, may tip the balance of age-related swallowing adaptations and compensation toward dysfunctional swallowing. To optimize swallowing assessment and management for our aging population, care must be taken not to oversimplify dysphagia complaints as a characteristic of aging.

Telomere shortening and frailty in Mexican older adults

AIM

Telomere shortening has been associated with several age-related diseases, in addition to being considered a hallmark of aging. Frailty is a clinical syndrome characterized by an accentuated physiological and functional decline that might be a predictor of an adverse condition in older age. The present study evaluated the relationship between frailty and telomere shortening in older adults from Mexico City, Mexico.

METHODS

This was a cross-sectional study. Data were collected from 323 frail older adults, including physical and environmental factors, such as body mass index, comorbidities, physical activity and tobacco consumption. Telomere length was measured by real-time polymerase chain reaction. The frailty syndrome was diagnosed using the Fried criteria.

RESULTS

An association between frailty and telomere shortening was found in both sexes. Telomere length decreased from 6.05 kb (5.54-6.48 kb) to 4.20 kb (3.80-4.54 kb; P < 0.001). It was also observed that tobacco consumption could be a significant modifying factor in the association between these two variables. Previous reports are contradictory, suggesting that there is no relationship between telomere length and frailty; however, it is possible that there are genetic and/or environmental variables to be elucidated, that might influence this association, particularly in the studied population.

CONCLUSIONS

Telomere length is inversely related to frailty in Mexican frail older adults, and tobacco consumption is the main environmental modifying factor. Geriatr Gerontol Int 2018; 18: 1286-1292.
