Gut microbiota influence frailty syndrome in older adults: mechanisms and therapeutic strategies.

Frailty syndrome denotes a decreased capacity of the body to maintain the homeostasis and stress of the internal environment, which simultaneously increases the risk of adverse health outcomes in older adults, including disability, hospitalization, falls, and death. To promote healthy aging, we should find strategies to cope with frailty. However, the pathogenesis of frailty syndrome is not yet clear. Recent studies have shown that the diversity, composition, and metabolites of gut microbiota significantly changed in older adults with frailty. In addition, several frailty symptoms were alleviated by adjusting gut microbiota with prebiotics, probiotics, and symbiosis. Therefore, we attempt to explore the pathogenesis of frailty syndrome in older people from gut microbiota and summarize the existing interventions for frailty syndrome targeting gut microbiota, with the aim of providing timely and necessary interventions and assistance for older adults with frailty.

Comparison of gut microbiota profiles between patients suffering from elderly frailty syndrome and non-frail elderly individuals.

BACKGROUND: Frailty syndrome is a state of increased vulnerability to stressors, marked by lowered physical strength and increased dependence on others. The well-established changes in gut microbiota associated with old age suggest a probable relationship between gut microbiota and frailty. METHODS AND RESULTS: This study was aimed at finding the relationship between gut microbiota and frailty syndrome, by comparing the sociodemographic data and the gut microbiota profiles of 23 non-frail and 14 frail elderly individuals. We used the quantitative polymerase chain reaction method (qPCR) to determine the bacterial loads of Bifidobacteria, Lactobacillus, Bacteroidetes, Prevotella, and Escherichia coli in stool samples from test subjects. We discovered a significant increase in the bacterial load of Prevotella in frail elderly individuals aged 70 or above. Other bacterial loads and ratios were not significantly different between the two groups. CONCLUSIONS: More comprehensive studies with larger sample sizes and encompassing a wider range of inflammation-related bacteria need to be performed to discover the existence and exact nature of these relations.

Cardiovascular disease risk factors and frailty syndrome in community-dwelling older adults: Results from the Amirkola Health and Aging Project Cohort Study.

BACKGROUND: Early diagnosis and control of risk factors affecting frailty syndrome (FS) in older adults may lead to changes in the health/disease process, prevention of disability and dependency in the older adults, and reduction of health care costs and mortality rates. The aim of this study was to determine the predictive role of CVD risk factors and FS in community-dwelling older adults of Amirkola city in Iran. METHODS: This descriptive-analytic cross-sectional study is part of the second phase of the Amirkola Health and Aging Project (AHAP) cohort study conducted since 2011 on all individuals ≥ 60 years in the city of Amirkola in northern Iran. Totally, 1000 older adults were included in the study and divided into three groups: frail (n = 299), pre-frail (n = 455), and non-frail (n = 246) older adults. In the present study, age ≥ 60 years, female sex, fasting blood sugar (FBS) ≥ 126 mg/dl, affected diabetes mellitus (DM), body mass index (BMI) ≥ 27 kg/m², waist circumference (WC) or abdominal obesity > 102 cm in men and > 88 cm in women, low-density lipoprotein (LDL) > 100 mg/dl, triglyceride > 150 mg/dl, cholesterol > 200 mg/dl, high-density lipoprotein (HDL) < 40 mg/dl and blood pressure (BP) > 90/140 mmHg, uric acid > 7 mg/dl and a positive smoking history were considered CVD risk factors. RESULTS: The results showed that with each centimeter increase in WC, the odds of frailty compared with non-frailty was 79% higher, and the odds of frailty compared with pre-frailty was 1.43 times higher in older adults. In addition, the prevalence of pre-frailty compared with non-frailty, pre-frailty, and non-frailty was 10.59 times, 6.08 times, and 73.83 times higher in older individuals > 84 years old, respectively. The results of the present study indicated that the prevalence of pre-frailty compared with non-frailty, frailty compared with pre-frailty, and frailty compared with non-frailty was 2.86 times, 3.01 times, and 14.83 times higher in older adults women, respectively. The comparison between frail and non-frail groups represented that in DM older adults, the prevalence of frailty compared with non-frailty was 1.84 times higher and that of frailty compared with pre-frailty was 98% higher. The older adults with an FBS ≥ 126 mg/dl were 53% more likely to become frail, and with each unit increase in uric acid, the odds of becoming frail increased 2.05 times compared with non-frail older adults, and pre-frail compared with non-frail increased 99%. CONCLUSION: The results demonstrated that CVD risk factors predictive of FS included central obesity, age > 84 years, female sex, DM, FBS ≥ 126, and uric acid > 7. This problem highlights the need for preventive strategies in the older adults who are simultaneously vulnerable to CVD and frailty.

Orthogeriatric co-management in pelvic and acetabular fractures.

BACKGROUND: Osteoporosis, age and frailty significantly impacts outcomes in fragility fractures of the pelvis, increasing morbidity and mortality. Identifying frailty aids in risk stratification and personalized care plans, enhancing recovery and reducing complications in older adults. Orthogeriatric co-management, an interdisciplinary approach combining orthopedics and geriatrics, optimizes care for older adults with fragility fractures. This model improves outcomes through integrated preoperative and postoperative care. This study examines the current literature for orthogeriatric co-management in pelvic ring or acetabular fractures, aiming to improve outcomes for older adults. CONCLUSION: Orthogeriatric co-management can be an effective tool to significantly enhances clinical care and reduces complications in older adults with pelvic ring and acetabular fractures. Studies demonstrate increased detection of urological complications and earlier patient mobilisation, alongside a notable decrease in revision surgery rates. The implementation of a specialized framework underscores the necessity for standardised orthogeriatric protocols, optimizing patient outcomes and satisfaction. Integrating geriatric expertise in surgical treatment addresses comorbidities more effectively and minimizes postoperative complications. The certification of such centers ensures adherence to quality standards, fostering continuous improvement in care. Standardised orthogeriatric management should extend to all older fracture patients.

[Frailty assessment in geriatric oncology.]

A review of the use of comprehensive geriatric assessment and its components in oncology is introduced. The evidence base for the increasing incidence of cancer in the elderly worldwide also presented. The management of older adults with cancer is challenging. Comprehensive Geriatric Assessment (CGA) has been shown by many authors to be a strong predictor of adverse events in geriatric oncology patients. CGA is recommended in oncology practice for many reasons: to identify health problems not usually detected in routine oncologic screening, to perform non-oncologic interventions, and to modify the cancer treatment plan. Comprehensive geriatric assessment is the gold standard in geriatric oncology for identifying patients at high risk for adverse outcomes and optimizing cancer treatment and overall management. Nevertheless, it can be stated that the final point in the search for evidence-based and effective frailty assessment tools in the practice of geriatric oncology has not yet been reached. It is concluded that the development of new scales and index scores, as well as the application of the CGA model in general, can provide adequate care for elderly cancer patients.

[Targeted use of comprehensive geriatric assessment tools in cardiology. Part II (literature review).]

This review presents a targeted examination of the application of comprehensive geriatric assessment tools across various cardiovascular pathologies, including acute coronary syndrome, myocardial infarction, acute and chronic heart failure, and aortic stenosis. It has been demonstrated that assessing patient frailty in cardiovascular pathology is crucial for determining both short-term and long-term prognosis, as well as for evaluating the risk of various complications during cardiac surgical interventions. Currently, there is active research into necessary measures aimed at improving outcomes in frail elderly patients with cardiovascular diseases, such as interdisciplinary rehabilitation and geriatric approaches. Frail patients with cardiovascular diseases should be considered as requiring a personalized approach in the provision of cardiological care, with a deep understanding of geriatric issues in the elderly, to reduce complications and improve prognosis.

[Targeted use of comprehensive geriatric assessment tools in cardiology. Part I (literature review).]

The purpose of this review is to demonstrate the importance of using a comprehensive geriatric examination in cardiology, including geriatric aspects of the management of this patient population. Until now, the Russian Federation has completely lacked a geriatric approach to the management of cardiological patients, which provides for consideration of international experience in this survey. The curation of elderly and elderly patients is complicated by the presence of geriatric syndromes and age-associated diseases leading to deterioration of quality of life, repeated hospitalizations, disability and risk of death. The leading geriatric syndrome in geriatric practice is senile asthenia and multiple comorbid polymorbid pathologies of the geriatric patient. A patient admitted to an acute care hospital with a history of cardiovascular comorbid pathology is primarily viewed as a patient at high risk for cardiovascular complications, omitting the risk of adverse outcomes, including loss of independence and impaired functional status. The following literature review demonstrates the importance of defining senile asthenia outside of the geriatrician's office, justifying the need for advanced training for cardiologists in geriatrics.

The under-recognition and significance of frailty syndrome - a geriatric and forensic conundrum.

Frailty syndrome occurs in elderly individuals with declining muscle mass (sarcopenia), unintentional weight loss, decreasing physical strength and activity, exhaustion, and slow ambulation. It significantly increases morbidity and mortality with cardiovascular, renal disease and neurological disorders, osteoporosis and fractures, endocrine and immunological dysfunction and a variety of malignancies. It is increasing in incidence as the population ages. However, unfortunately as identification relies on clinical and not pathological evaluations, its contribution to a wide range of comorbidities and its role in terminal episodes may not be recognized in a forensic context.

Impact of frailty on clinical outcomes and resource utilization of hospitalizations for renal stone surgery.

PURPOSE: Frailty is reportedly associated with poorer outcomes among surgical patients. Using a coding-based frailty tool, we investigated the impact of frailty on clinical outcomes and resource utilization for urolithiasis hospitalizations. METHODS: A cohort study using the 2018 National Inpatient Sample database. All adult elective hospitalizations for urolithiasis were included in the study. The study population was categorized into FRAIL and non-frail (nFRAIL) cohorts using the Johns Hopkins Adjusted Clinical Groups frailty clusters. The association between frailty and clinical and financial outcomes was evaluated using multivariate regression models. RESULTS: About 1028 (14.9%) out of 6900 total hospitalizations were frail. Frailty was not associated with a significant increase in the odds of in-hospital mortality (adjusted odds ratio (aOR) 1.73, 95% CI 0.15-20.02) or length of hospital stay, but was associated with a lower chance of surgery within 24 h of admission (aOR 0.65, 95% CI 0.48-0.90, P = 0.008). A higher Charlson index was independently associated with an over 100% increase in the odds of in-hospital mortality (aOR 2.091, 95% CI 1.53-2.86, P < 0.001). Frail patients paid $15,993 higher in total hospital costs and had a higher likelihood of non-home discharges (aOR 4.29, 95% CI 2.74-6.71, P < 0.001) and peri-operative complications (aOR 1.77, 95% CI 1.14-2.73, P = 0.01). CONCLUSION: Frailty was correlated with unfavorable outcomes, except mortality and prolonged hospital stay. Incorporating frailty evaluation into risk models has the potential to enhance patient selection and preparation for urolithiasis intervention.

EHRA expert consensus document on the management of arrhythmias in frailty syndrome, endorsed by the Heart Rhythm Society (HRS), Asia Pacific Heart Rhythm Society (APHRS), Latin America Heart Rhythm Society (LAHRS), and Cardiac Arrhythmia Society of Southern Africa (CASSA).

There is an increasing proportion of the general population surviving to old age with significant chronic disease, multi-morbidity, and disability. The prevalence of pre-frail state and frailty syndrome increases exponentially with advancing age and is associated with greater morbidity, disability, hospitalization, institutionalization, mortality, and health care resource use. Frailty represents a global problem, making early identification, evaluation, and treatment to prevent the cascade of events leading from functional decline to disability and death, one of the challenges of geriatric and general medicine. Cardiac arrhythmias are common in advancing age, chronic illness, and frailty and include a broad spectrum of rhythm and conduction abnormalities. However, no systematic studies or recommendations on the management of arrhythmias are available specifically for the elderly and frail population, and the uptake of many effective antiarrhythmic therapies in these patients remains the slowest. This European Heart Rhythm Association (EHRA) consensus document focuses on the biology of frailty, common comorbidities, and methods of assessing frailty, in respect to a specific issue of arrhythmias and conduction disease, provide evidence base advice on the management of arrhythmias in patients with frailty syndrome, and identifies knowledge gaps and directions for future research.

Aging and the impact of global DNA methylation, telomere shortening, and total oxidative status on sarcopenia and frailty syndrome.

Aging is a biological event that influences many organs and systems. Both sarcopenia and frailty syndrome refer to geriatric conditions with overlapping phenotypes. Many mechanisms are involved in the aging process such as DNA methylation telomeres which are susceptible to oxidative stress, and inflammations which result in telomere shortening, leading to chromosomal instability. The study aimed to determine the associations between these processes, frailty and sarcopenia syndrome. Global DNA methylation was analyzed using the ELISA method. Telomere length was analyzed using qPCR. Total oxidative status (TOS) was analyzed using a colorimetric method. The present study revealed that the main factor affecting methylation, telomeres length and level of total oxidant stress was age.

Expression of Prostaglandin Genes and ß-Catenin in Whole Blood as Potential Markers of Muscle Degeneration.

Prostaglandin signaling pathways are closely related to inflammation, but also muscle regeneration and processes associated with frailty and sarcopenia, whereas ß-catenin (CTNNB1 gene) as a part of Wnt signaling is also involved in the differentiation of muscle cells and fibrosis. The present study analyzed the association between selected prostaglandin pathway genes and clinical parameters in patients with sarcopenia and frailty syndrome. The present study was conducted on patients with sarcopenia, frailty syndrome, and control older patients (N = 25). Additionally, two healthy controls at the age of 25-30 years (N = 51) and above 50 years old (N = 42) were included. The expression of the PTRGER4, PTGES2 (COX2), PTGS2, and CTNNB1 genes in whole blood was checked by the qPCR method. The serum cytokine levels (IL-10, TNFα, IFN-y, IL-1α, IL-1ß) in patients and controls were checked by the Q-Plex Human Cytokine Panel. The results showed a significant effect of age on PTGER4 gene expression (p = 0.01). A negative trend between the appendicular skeletal muscle mass parameter (ASSM) and the expression of PTGER4 has been noted (r = -0.224, p = 0.484). PTGES2 and PTGS2 expressions negatively correlated with creatine phosphokinase (r = -0.71, p = 0.009; r = -0.58, p = 0.047) and positively with the functional mobility test timed up and go scale (TUG) (r = 0.61, p = 0.04; r = 0.63, p = 0.032). In the older control group, a negative association between iron levels and the expression of PTGS2 (r = -0.47, p = 0.017) was observed. A similar tendency was noted in patients with sarcopenia (r = -0.112, p = 0.729). A negative trend between appendicular skeletal muscle mass (ASMM) and PTGER4 seems to confirm the impairment of muscle regeneration associated with sarcopenia. The expression of the studied genes revealed a trend in associations with the clinical picture of muscular dystrophy and weakening patients. Perhaps PTGS2 and PTGES2 is in opposition to the role of the PTGER4 receptor in muscle physiology. Nevertheless, further, including functional studies is needed.

[Audiological testing in complex geriatric assessment of patients.]

The aim of the study is to evaluate the advantage of including audiological testing in the system of comprehensive geriatric assessment (CGA) of patients. The results of a survey of 988 elderly and senile people (average age 77±7,4 years) are presented, each of whom underwent a CGA and hearing assessment by filling out a questionnaire Hearing Handicap Inventory for the Elderly, Screening version (HHIE-S). All patients were divided into two groups: the first group included 780 inpatient patients undergoing medical and social rehabilitation in different departments of the Saint-Petersburg City Geriatric Center. The second group included 208 outpatient patients, of whom 81 additionally underwent an audiological examination, which included ENT examination and pure tone audiometry to determine the degree of hearing loss. A correlation was revealed between the hearing state and the cognitive status of patients according to the results of the Mini-Mental State Examination (MMSE) questionnaire, as well as the senile asthenia index. The results of the work indicate the need to include the HHIE-S questionnaire in the system of comprehensive geriatric assessment for early detection and correction of hearing loss, and prevention of cognitive disorders.

THE FRAMEWORK OF THE PILOT PROJECT FOR TESTING A TELEMEDICINE MODEL IN THE FIELD OF GERIATRICS - HEALTH CHALLENGES AND JUSTIFICATION OF THE PROJECT IMPLEMENTATION.

OBJECTIVE: Aim: To present the essentials of the pilot project for testing a telemedicine model in the field of geriatrics, along with a snapshot of the health challenges. PATIENTS AND METHODS: Materials and Methods: This review paper use the synthetic method summarizing the main objectives of the telemedicine project in the field of geriatrics. The described project involving telemedical care of patients with geriatric complexes in the area of frailty syndrome, sarcopenia and malnutrition, according to the proposed model addresses the aforementioned problems. The project provides a holistic model of home and outpatient care, which will allow concerting on 3 groups of the above-mentioned geriatric syndromes. The project will have a pilot character and is aimed at clinical verification through the introduction (implementation) of the new method and accompanying organizational and technological solutions (platform, equipment) in an area where current models and schemes of therapeutic and diagnostic support were insufficient. CONCLUSION: Conclusions: The implementation of telemedicine solutions creates an opportunity for geriatric patients and their families by improving access to specialized medical care. This project will support patients, but also caregivers, who (through training and telemedicine) will be better able to provide care services with the ability to reconcile them with their own work.

Inflammation and cell-to-cell communication, two related aspects in frailty.

BACKGROUND: Frailty is a complex, multi-dimensional age-related syndrome that increases the susceptibility to adverse health outcomes and poor quality of life. A growing consensus supports the contribution of chronic inflammation and immune system alterations to frailty, however a clear role of such alterations remains to be elucidated. Furthermore, pro- and anti-inflammatory cytokines together with other signaling molecules might spread from activated cells to the adjacent ones through extracellular vesicles (EVs), which have also a role in cellular aging. The aim of the present research was to investigate if EVs play a role in the immune function in frailty.  RESULTS: In 219 older adults aged 76-78 years, selected from the InveCe.Ab study (Abbiategrasso, Italy), we investigated inflammation and EVs-mediated intercellular communication. C-reactive protein (CRP) and pro- (IL-1ß, IL-2, IL-6, IL-8, IL-12 p70, TNFα and IFNγ) and anti- (IL-4, IL-10, IL-13) inflammatory cytokines were evaluated on plasma of Frail and non-Frail subjects. We reported a significant increase in CRP, interleukin-1ß and -6 (IL-1ß, IL-6) and tumor necrosis factor alpha (TNFα) plasma levels in frailty. In female Fr subjects, we also reported an increase in interferon-gamma (IFN-γ) and, surprisingly, in IL-13, an anti-inflammatory cytokine, whose increase seems to oppose the inflammaging theory. An inflammatory panel (toll-like receptors 2 and 4 (TLR2 and TLR4), tumor necrosis factor receptors TNFRec5/CD 40 and TNFRec1B/CD120B) and a panel including receptors involved in cellular senescence (insulin-like growth factor 1 receptor (CD221) and interleukin 6 receptor (IL-6R)) were indeed analysed in plasma isolated large EVs (lEVs) from Frail (n = 20) and non-Frail (n = 20) subjects. In lEVs isolated from plasma of Frail subjects we reported an increase in TLR2 and TLR4, TNFRec5/CD 40 and TNFRec1B/CD120B, suggesting a chronic state of inflammation. In addition, CD221 and IL-6R increases in lEVs of Frail individuals. CONCLUSIONS: To conclude, the pro-inflammatory status, notably the increase in circulating cytokines is pivotal to understand the potential mechanisms underlying the frailty syndrome. Moreover, cytokines release from EVs, mainly the large ones, into the extracellular space suggest their contribution to the formation of a pro-inflammatory and pro-senescent microenvironment that, in turn, can contribute to frailty.

Frail older adults show a distinct plasma microvesicle profile suggesting a prothrombotic and proinflammatory phenotype.

In a global context of advanced aging, geriatric diseases such as frailty syndrome face challenges in the search for biomarkers and preventive strategies. Frailty has been associated with atherothrombotic pathologies. Circulating microvesicles (cMVs), phospholipid-rich vesicles with a size of 0.1-1.0 µm, have been shown to participate in atherothrombosis onset and progression. We have hypothesized that cMVs from platelets, and vascular and immune cells, are increased in frail older adults. To verify this, a prevalent-case control study was designed with 28 frail older and 27 nonfrail older adults older than 64 years. Frailty was defined by Fried's phenotype. Total cMVs, annexin V positive (AV+)-cMVs, and annexin V negative (AV- )-cMVs derived from blood and vascular cells were measured by flow cytometry. In the analysis of total cMVs, the frail group presented higher levels of CD14+ /CD142+ (p = .042), CD41a+ /CD142+ (p = .041), and CD56+ (p = .025), CD14+ cMVs (p = .043), and CD16+ /CD14+ (p = .019) cMVs levels. Within the phosphatidylserine-exposing cMVs (AV+ ), the frail group showed higher CD14+ /AV+ (p = .044), CD9+ /AV+ (p = .031), P2RY12+ /AV+ (p = .028), and CD235a+ /AV+ (p = .043) cMVs concentrations. Finally, within AV- cMVs, the frail group showed higher CD142+ /CD41a+ /AV- cMVs concentrations originated from platelets (p = .027), CD56+ /AV- originated from natural killer cells (p = .022), and CD34+ /AV- cMVs from hematopoietic stem cells (p = .037). In summary, frail older adults present higher concentrations of platelet-, leukocyte-, and hematopoietic cell-derived cMVs compared to robust age-matched older adults. These cMVs may be involved in the deregulation of the immune system, endothelial damage, and increased risk of thrombosis associated with frailty.

PTPN22 gene functional polymorphism (rs2476601) in older adults with frailty syndrome.

The frailty syndrome is a common clinical marker of vulnerability in older adults conducive to an overall decline in inflammatory stress responsiveness; yet little is known about the genetic risk factors for frailty in elderly. Our aim was to investigate the association between the rs2476601 polymorphism in PTPN22 gene and susceptibility to frailty in Mexican older adults. Data included 630 subjects 70 and older from The Coyoacán cohort, classified as frail, pre-frail, and non-frail following Fried's criteria. Sociodemographic and clinical characteristics were compared between groups at baseline and after a multivariate analysis. The rs2476601 polymorphism was genotyped by TaqMan genotyping assay using real-time PCR and genotype frequencies were determined for each frailty phenotype in all participants and subsets by age range. Genetic association was examined using stratified and interaction analyses adjusting for age, sex and variables selected in the multivariate analysis. Disability for day-life activities, depression and cognitive impairment were associated with the risk of pre-frailty and frailty at baseline and after adjustment. Carrying the T allele increased significantly the risk of frailty in patients 76 and older (OR 5.64, 95% CI 4.112-7.165) and decreased the risk of pre-frailty under no clinical signs of depression (OR 0.53; 95% CI 0.17-1.71). The PTPN22 polymorphism, rs2476601, could be a genetic risk factor for frailty as subject to quality of life. This is the first study analyzing such relationship in Mexican older adults. Confirming these findings requires additional association studies on wider age ranges in populations of older adults with frailty syndrome.

The influence of frailty syndrome on quality of life in elderly patients with type 2 diabetes.

INTRODUCTION: There have been no comprehensive studies that assess the impact of frailty syndrome on quality of life (QoL) of patients with diagnosed type 2 diabetes. The purpose of the study was to assess the impact of frailty syndrome on QoL and depression symptoms of patients with type 2 diabetes. METHODS: The study included 148 consecutive patients (aged ≥ 60y). The patients were divided into two groups according to the prevalence of the frailty syndrome: robust and frailty. For all of the patients that were included in the study, we used the Polish version of validated instruments: ADDQoL, TFI and BDI. RESULTS: In the study group, 43.2% had been diagnosed with frailty syndrome. An analysis of QoL assessment depending on the prevalence of the frailty syndrome showed that patients who were robust (without recognized frailty syndrome) assessed QoL significantly better than patients with coexisting frailty syndrome. Robust patients did not have any severe depressive symptoms, whereas in the group of patients with the frailty syndrome 43.8% of the patients had a depression. 70.2% of the patients without any depressive symptoms were robust patients, meanwhile only 14% of the patients had frailty syndrome recognized. CONCLUSIONS: Frailty syndrome occurred in 43 percent of the patients with type 2 diabetes. This has a negative impact on QoL of patients. Depression is more common in patients with the frailty syndrome and diabetes.

Unobtrusive Sensors for the Assessment of Older Adult's Frailty: A Scoping Review.

Ubiquity (devices becoming part of the context) and transparency (devices not interfering with daily activities) are very significant in healthcare monitoring applications for elders. The present study undertakes a scoping review to map the literature on sensor-based unobtrusive monitoring of older adults' frailty. We aim to determine what types of devices comply with unobtrusiveness requirements, which frailty markers have been unobtrusively assessed, which unsupervised devices have been tested, the relationships between sensor outcomes and frailty markers, and which devices can assess multiple markers. SCOPUS, PUBMED, and Web of Science were used to identify papers published 2010-2020. We selected 67 documents involving non-hospitalized older adults (65+ y.o.) and assessing frailty level or some specific frailty-marker with some sensor. Among the nine types of body worn sensors, only inertial measurement units (IMUs) on the waist and wrist-worn sensors comply with ubiquity. The former can transparently assess all variables but weight loss. Wrist-worn devices have not been tested in unsupervised conditions. Unsupervised presence detectors can predict frailty, slowness, performance, and physical activity. Waist IMUs and presence detectors are the most promising candidates for unobtrusive and unsupervised monitoring of frailty. Further research is necessary to give specific predictions of frailty level with unsupervised waist IMUs.

Prevalence and Correlates of Frailty Syndrome among Older Adults Attending Chief Tony Anenih Geriatric Centre, University College Hospital, Ibadan.

BACKGROUND: Frailty has emerged as an important clinical measurement among older adults because of its negative health outcomes. OBJECTIVE: This study measured the prevalence and factors associated with frailty among older adults aged 60 years and above at a Geriatric Centre in Nigeria. METHODS: In this descriptive cross-sectional study, 971 older adults were recruited consecutively. Data on sociodemographics characteristics and clinical parameters were obtained using an interviewer-administered questionnaire and physical examination performed. The Frailty syndrome and Frailty Index were assessed using the Fried Frailty Criteria (FFC) and Canadian Study of Health and Aging (CSHA) scale respectively. Bivariate and multivariate analyses were carried out using SPSS version 21 at a p <0.05. RESULTS: The mean age of the participants was 71.3 (± 7.1) years with a female to male ratio of 2.4:1. Based on FFC scale, 498 older persons (51.3%) had frailty syndrome while only 148 (15.2%) were frail using the CSHA scale. The measure of agreement (Kappa statistics) was 0.22 (p<0001) indicating weak agreement between the two scales. Logistic regression analysis revealed increasing age (OR=1.948 [1.219-3.113]), multiple morbidities (OR= 1.584, [1.177-2.201]), depression (OR= 5.050, [2.501-9.442,]), imbalance or increased risk of fall (OR 1.623, [1.192-2.211,]), and inability to perform IADL (OR= 0.599 [0.535-0.670,]) to be the most significant determinants of frailty syndrome while obesity (OR=0.660, [0.449-0.971]), unusually appeared a deterrent. CONCLUSION: The prevalence of frailty syndrome was high among the older adults. Targeted and timely interventions on the modifiable factors may delay progression into frailty and the eventual negative health outcomes.

CONTEXTE: La fragilité a ete emerge comme un élément clinique important mesure chez les personnes âgées en raison de son état de santé négatif les résultats. OBJECTIF: Cette étude a mesuré la prévalence et les facteurs associée à la fragilité chez les personnes âgées de 60 ans et cidessus dans un centre gériatrique au Nigéria. MÉTHODES: Dans cette étude transversale descriptive, 971 des adultes plus âgés ont été recrutés consécutivement. Les données sur les caractéristiques sociodémographiques et les paramètres cliniques ont été obtenu à l'aide d'un questionnaire administré par l'enquêteur et un examen physique effectué. Le syndrome de fragilité et l'indice de fragilité ont été évalués à l'aide du Fried Frailty Critères (FFC) et étude canadienne sur la santé et le vieillissement (CSHA) respectivement. Bivarié et multivarié les analyses ont été réalisées à l'aide de SPSS version 21 à p <0,05. RÉSULTATS: L'âge moyen des participants était de 71,3 (± 7,1) ans avec un ratio femmes / hommes de 2,4: 1. Basé sur l'échelle FFC, 498 personnes âgées (51,3%) avaient un syndrome de fragilité alors que seulement 148 (15,2%) étaient fragiles selon l'échelle de la SCVS. La mesure d'accord (statistiques Kappa) était de 0,22 (p <0001) indiquant faible accord entre les deux échelles. Une analyse de régression logistique a révélé une augmentation de l'âge (OR = 1,948 [1,219-3,113]), morbidités multiples (OR = 1,584, [1.177-2.201]), dépression (OR = 5.050, [2.501-9.442,]), déséquilibre ou risque accru de chute (OR 1.623, [1.192-2.211,]), et l'incapacité d'effectuer une IADL (OR = 0,599 [0,535-0,670,]) pour être les déterminants les plus importants du syndrome de fragilité obésité (OR = 0,660, [0,449-0,971]), apparaissait inhabituellement dissuasif. CONCLUSION: La prévalence du syndrome de fragilité était élevée parmi les personnes âgées. Interventions ciblées et opportunes sur les facteurs modifiables peuvent retarder la progression vers la fragilité et les éventuels effets négatifs sur la santé.
