AbstractDNA methylation age acceleration (DNAmAA, derived from an epigenetic clock) and relative leukocyte telomere length (rLTL) are widely accepted biomarkers of aging. Nevertheless, it is still unclear which aspects of aging they represent best. Here we evaluated longitudinal associations between baseline rLTL and DNAmAA (estimated with 7-CpG clock) and functional assessments covering different domains of aging. Additionally, we made use of cross-sectional data on these assessments and examined their association with DNAmAA estimated by five different DNAm age measures.Two-wave longitudinal data was available for 1,083 participants of the Berlin Aging Study II (BASE-II) who were re-examined on average 7.4 years after baseline as part of the GendAge study. Functional outcomes were assessed with Fried’s frailty score, Tinetti mobility test, falls in the past 12 months (yes/no), Finger-floor distance, Mini Mental State Examination (MMSE), Center for Epidemiologic Studies Depression Scale (CES-D), Activities of Daily Living (ADL), Instrumented ADL (IADL) and Mini Nutritional Assessment (MNA).Overall, we found no evidence for an association between the molecular biomarkers measured at baseline, rLTL and DNAmAA (7-CpG clock), and functional assessments assessed at follow-up. Similarly, a cross-sectional analyses of follow-up data did also not show evidence for associations of the various DNAmAA measures (7-CpG clock, Horvath’s clock, Hannum’s clock PhenoAge, and GrimAge) with functional assessments.In conclusion, neither rLTL nor 7-CpG DNAmAA were able to predict impairment in the analyzed assessments over a ∼7 year time-course. Similarly, DNAmAA as estimated by five epigenetic clocks was not a good cross-sectional marker of health deterioration either.

Abstract Background Malnutrition is an important cause of morbidity and mortality. Malnutrition increases the number of hospitalizations and prolongs the length of hospitalization by disrupting organ functions, increasing the number and severity of infections and delaying wound healing. The aim of this study was to determine the frequency of suspected malnutrition in the elderly, to examine some related variables and to evaluate the depression. Methods The study is a cross-sectional study conducted between March-April 2019 in individuals aged 60 years and older living in Sivrihisar. Sample size was calculated as 579. Cluster sampling method used. Data was collected by door to door in 4 neighborhoods determined by randomly. Mini Nutritional Assessment Test-Short Form (for malnutrition), Katz Daily Living Activities Scale (for dependency) and Geriatric Depression Scale-Short Form (for depression) were used. Chi-square test, Mann Whitney U test and logistic regression analysis were used for the analyzes. Results The study group consisted of 220 (38%) women and 359 (62%) men. The mean age was 68.9±6.4 (ranged 60-93). Frequency of suspected malnutrition was 25% (n = 145). Being 80 years of age or older (OR:3.24, CI:1.53-6.85), having a primary and lower education level (OR:2.54, CI:1.32-4.90), history of chronic illness (OR:2.34, CI:1.33-4.03), using dentures (OR:1.62, CI:1.03-2.55) and suspected depression (OR:4.97, CI:3.17-7.78) are important risk factors for malnutrition. Those with suspicion of malnutrition had lower scores on DLA (z = 8.982;p=0.001). Conclusions Malnutrition was found to be an important health problem for the elderly. The frequency of suspected malnutrition is higher in individuals with depression. Those with suspected malnutrition have higher level of dependency. In order to reduce the frequency of malnutrition, it may be beneficial to increase the awareness of the elderly and caregivers and to give importance to the elderly nutrition of primary health care providers. Key messages Depression is an important risk factor for malnutrition. Malnutrition increases the dependence of the individual on daily activities.

Many people living with HIV (PLWH) are aging with geriatric syndromes, but few undergo comprehensive geriatric assessment (CGA) due to limited resources. Our study evaluates tools to identify aging PLWH who may forego CGA. We conducted a cross-sectional study on 357 PLWH ≥50 years old at the Red Cross, Thailand. Tools evaluated were the Veterans Aging Cohort Study Index (VACSI) and G-8, which is predictive among older cancer patients. CGA consists of eight tests: history of fall within 12 months, timed-up-and-go test (TUG), activities of daily living (ADL), instrumental ADL (IADL), Montreal cognitive assessment (MoCA), Thai depression scale (TDS), mini nutritional assessment (MNA), and HIV symptom index (HSI). We considered ≥2 impaired domains on CGA to be abnormal results. Forty-nine percent (n = 175) had ≥2 impaired domains on CGA. Few participants had experienced a fall (11%) or abnormal TUG/ADL/IADL (<2%), and only MoCA/TDS/MNA/HSI were analyzed. A VACSI < 17 produces 85% sensitivity (Se) and 30% specificity (Sp) (area under the ROC curve [AUC] = 63, 95%CI 58–69) and G-8 > 15.5 produces 90%Se and 33%Sp (AUC = 74, 95%CI 69–79) in identifying patients with <2 impaired domains. A G-8 > 13.5 produces 91%Se and 77%Sp (AUC = 89, 95%CI 86–92) in ruling out abnormal nutrition. Patients with VACSI < 17 and G-8 > 15.5 may forego CGA due to low likelihood of abnormal cognition, mood, nutrition, or symptom burden.

Abstract Objectives To screen elderly participants for early Dementia in primary care in Egypt using a newly developed Early Dementia Questionnaire (EDQ) and comparing it with standard assessment tool, Mini Mental State Examination (MMSE). Design A cross-sectional study. Setting and Participants The study included 220 elder adults (both men and women) recruited from a primary healthcare center, the outpatient geriatric clinic at Ain Shams University hospitals and elderly clubs (Community dwelling) in Cairo Governorate, Egypt. Methods A cross-sectional study was conducted on a group of elderly patients using systematic random sampling. Elderly depression was excluded using the Geriatric Depression Scale (GDS). Diagnosed cases of dementia and other mental or psychiatric disorders and illiterate participants were excluded from the study. A face-to-face interview was done using EDQ with the participants to elicit symptoms of early dementia. The participants were then assessed with MMSE using variable cut-off points according to age and educational level. Results Prevalence of dementia among the study participants was 81.4% by EDQ and 19.5% by MMSE. The EDQ demonstrated a sensitivity of 97.7% with specificity of 22.6%. Positive predictive value of EDQ was 23.5% with the negative predictive value of 97.6%. A significant association was found between possible dementia, hypertension, Mini Nutritional Assessment and urinary incontinence. Conclusion The EDQ is more sensitive than MMSE for screening of early dementia.

Todays challenge in geriatric oncology is to screen patients who need geriatric follow-up. The main goal of this study was to analyze factors that identify patients, in a large cohort of patients with solid tumors, who need more geriatric interventions and therefore specific follow-up. Between April 2012 and May 2018, 3530 consecutive patients were enrolled in the PACA EST cohort (France). A total of 3140 patients were finally enrolled in the study. A Comprehensive Geriatric Assessment (CGA) was performed at baseline. We analyzed the associations between factors at baseline (geriatric and oncologic factors) and the need to perform more than three geriatric interventions. The mean age of the population was 82 years old with 59% of patients aged older than 80 years old. A total of 8819 geriatric interventions were implemented for the 3140 patients. The percentage of patients with three or more geriatric interventions represented 31.8% (n = 999) of the population. In multivariate analyses, a Mini Nutritional assessment (MNA) <17, an MNA ≤23·5 and ≥17, a performans status (PS) >2, a dependence on Instrumental Activities of Daily Living (IADL), a Geriatric Depression Scale (GDS) ≥5, a Mini Mental State Examination (MMSE) <24, and a Screening tool G8 ≤14 were independent risk factors associated with more geriatric interventions. Factors associated with more geriatric interventions could assist practitioners in selecting patients for specific geriatric follow-up.

Objectives: To investigate the prevalence of depression among the oldest old and to analyze factors associated with depression.Methods:A cross-sectional, population-based study was undertaken in Umeå, Sweden. Out of 319 eligible participants aged 85, 90 and 95 years and older, it was possible to evaluate 242 people (75.9%) for depression. Data were collected from structured interviews and assessments in the participants’ homes, and from medical charts, relatives and caregivers. Depression was screened for using the Geriatric Depression Scale-15 and further assessed with the Montgomery–Åsberg Depression Rating Scale. Cognition was assessed using the Mini-mental State Examination, activities of daily living (ADL) using the Barthel ADL Index, nutrition using the Mini Nutritional Assessment and well-being using the Philadelphia Geriatric Center Morale Scale.Results:The 85-year-olds had a significantly lower prevalence of depression than the 90- and 95-year-olds (16.8% vs. 34.1% and 32.3%). No sex differences were found. One-third of those with depression had no treatment and among those with ongoing treatment 59% were still depressed. Persons diagnosed with depression had a poorer well-being and a higher 1-year mortality. Logistic regression analyses showed that depression was independently associated with living in institutions and number of medications.Conclusion:Depression among the oldest old is common, underdiagnosed and inadequately treated, and causes poor well-being and increased mortality. More knowledge about depression is essential to improve the assessment and treatment of depression among the oldest old.

AbstractCancer-related malnutrition has a high prevalence, reduces survival and increases side effects. The aim of this study was to assess oncology outpatients and risk of malnutrition. Reported symptoms and quality of life (QoL) in patients found to be at risk of malnutrition or malnourished were compared to patients without malnutrition. Using a standardized questionnaire, the European Organization for Research and Treatment of Cancer Questionnaire for Quality of Life and the Mini Nutritional Assessment (MNA), patients in an outpatient cancer clinic undergoing chemotherapy treatment at a German University Hospital were assessed for nutrition, risk of malnutrition and quality of life. Based on the MNA, 39 (45.9%) patients were categorized as malnourished or at risk for malnutrition. Loss of appetite (n = 37.6%, p < 0.001) and altered taste sensation (n = 30,3%, p < 0.001) were the symptoms most frequently associated with reduced food intake. Patients with risk of malnutrition scored lower on the global health status (n = 48.15%, p = 0.001). Side effects of cancer treatments lead to a higher risk of malnutrition and as a consequence lower QoL. These side effects should be addressed more efficiently in cancer care.

Aim: To compare anticholinergic burden (ACB) in older patients with and without cancer and evaluate the effects of ACB on geriatric syndromes. Methods: A total of 291 patients from the geriatric clinic and 301 patients from the oncology clinic were evaluated. ACB <2 was categorized as low ACB and ACB ≥2 was categorized as high ACB. A comprehensive geriatric assessment was performed on patients from the geriatric clinic. Results: ACB scores were significantly higher in patients without cancer compared with those with cancer (p < 0.005). Number of falls and Geriatric Depression Scale 15 scores were higher and Mini-Nutritional Assessment and Barthel/Lawton activities of daily living scores were lower in geriatric patients with high ACB scores compared with those with low ACB scores (p < 0.005). Conclusion: It is crucial to understand the potential effects of ACB for rational drug use and optimum cancer management in older patients with cancer.

Abstract Growth differentiation factor 15 (GDF15) is a stress-induced cytokine. Its plasma levels increase during aging and acute illness. In older Patients and age-matched Controls, we evaluated whether GDF15 levels (i) were associated with recovery after acute illness, and (ii) reflected different trajectories of aging and longitudinal changes in health measures. Fifty-two older Patients (≥65 years) were included upon admission to the emergency department (ED). At 30 days after discharge (time of matching), Patients were matched 1:1 on age and sex with Controls who had not been hospitalized within 2 years of inclusion. Both groups were followed up after 1 year. We assessed plasma levels of GDF15 and inflammatory biomarkers, frailty, nutritional status (mini nutritional assessment short-form), physical and cognitive function, and metabolic biomarkers. In Patients, elevated GDF15 levels at ED admission were associated with poorer resolution of inflammation (soluble urokinase plasminogen activator receptor [suPAR]), slowing of gait speed, and declining nutritional status between admission and 30-day follow-up. At time of matching, Patients were frailer and overall less healthy than age-matched Controls. GDF15 levels were significantly associated with participant group, on average Patients had almost 60% higher GDF15 than age-matched Controls, and this difference was partly mediated by reduced physical function. Increases in GDF15 levels between time of matching and 1-year follow-up were associated with increases in levels of interleukin-6 in Patients, and tumor necrosis factor-α and suPAR in age-matched Controls. In older adults, elevated GDF15 levels were associated with signs of accelerated aging and with poorer recovery after acute illness.

Abstract Objective Nutritional assessment can early identify patients who are malnourished and at risk of malnutrition. To examine the effect of nutritional status on wound healing in elderly burn patients, we used the MNA-SF to measure the nutritional status of elderly patients. This study aimed to examine the role of MNA-SF in elderly burn patients through the correlation analysis of wound-healing indicators and MNA-SF score. Design Prospective observational and cross-sectional study. Methods This study used the MNA-SF to investigate the elderly burn patients at the department of burn. According to the score, the patients fell into three groups: good nutritional status (more than 12 points), malnutrition risk (8~11 points), and malnutrition (0~7 points). At the same time, we measured and compared the wound-healing indicators among the three groups of patients, and detected the correlation. Results The statistical analysis found gender had a slight influence on the score of nutritional status. While age was negatively correlated with the MNA-SF score and nutrition-related indicators. There was a low positive linear correlation between the wound healing percent area change or wound healing rate of patients and the score of the MNA-SF. Conclusion This study finds malnutrition is common among hospitalized elderly burn patients. The application of the MNA-SF in elderly burn patients is efficient and accurate to identify malnutrition early and prevent further obstruction of the normal wound healing, which can provide reference points for early nutrition intervention programs.
