Sarcopenia and poor nutritional status in older adults.

BACKGROUND & AIMS: The association between sarcopenia and malnutrition has been poorly studied in the older population. The purpose of this study is to address the association between sarcopenia, according to different validated definitions, and nutritional status in a large population of community-dwelling older adults. METHODS: Observational, cross-sectional study of the Geriatric Frailty Clinic (GFC) for Assessment of Frailty and Prevention of Disability, held by the "Gérontopôle" of the Toulouse University Hospital. Patients aged above 65 years who benefitted from a Dual X-ray Densitometry (DXA) during their assessment at the GFC from June 5th 2013 to January 28th 2020 were included. Sarcopenia was defined according to proposed validated definitions. The Mini Nutritional Assessment (MNA) was used to stratify nutritional status, and identify patients with a poor nutritional status (at risk of malnutrition or malnourished, MNA <24). Multiple logistic regression analyses were performed between MNA and each sarcopenia definition adjusted for confounders. RESULTS: Among the 938 patients with DXA data, a total of 809 (86.2 %) subjects were included in the analysis (mean age 81.8 ± 6.9 years, 527 females (65.1 %)). Prevalence of sarcopenia ranged from 12.6 % to 44.9 %, according to various definitions. Overall 244 (30.2 %) of the patients had a poor nutritional status (MNA-score <24), Baumgartner and Newman definitions of sarcopenia were both associated with low MNA-scores (OR = 4.69, CI 3.15-6.98 and OR = 2.30, CI 1.55-3.14, respectively), EWGSOP2 "confirmed sarcopenia" definition was also associated with low MNA-scores (OR = 3.68, CI 2.30-5.89), as well as for the lean mass definition according EWGSOP2 cut-off (OR 5.22 CI 3.52-7.73). Both FNIH and EWGSOP2 "probable sarcopenia" definitions were not associated with the risk of malnutrition. CONCLUSIONS: In this study, the prevalence of sarcopenia ranged from 12.6 to 44.9 % according to various definitions. A score of MNA under 24, was associated with almost all of the sarcopenia definitions. This study reinforces the concept that malnutrition and sarcopenia are strictly related. When facing malnutrition in daily clinical practice, body composition should be assessed and the proposed nutritional intervention should be tailored by these results in order to prevent the onset of late-life disability.

Amiodarone-induced Ataxia: A Case Report of Severe Cerebellar Dysfunction and Review of Literature.

Amiodarone therapy is widely prescribed in patients with atrial fibrillation. The higher prevalence of this arrhythmic heart disease, and the specific age-related issues of homeostasis in the elderly population, makes this group particularly exposed to its adverse effects. Among the many described side-effects, neurological impairments are the less documented and studied. Because amiodarone can be responsible for severe complications, as described in the case below, a close monitoring is necessary throughout its prescription. Awareness should be brought on the amiodarone-induced neurological side-effects as they could be overlooked.

No Difference in the Phenotypic Expression of Frailty among Elderly Patients Recently Diagnosed with Cancer Vs Cancer Free Patients.

OBJECTIVES: To examine frailty determinants differences in patients with a recent diagnosis of cancer compared to non-cancer patients among older adult. Revealing those differences will allow us to individualize the exact frailty management in those patients diagnosed with cancer. DESIGN: This is an observational cross-sectional, monocentric study. SETTING: Patients were evaluated at the Geriatric Frailty Clinic (GFC), in the Toulouse University Hospital, France, between October 2011 and February 2016. PARTICIPANTS: 1996 patients aged 65 and older were included (1578 patients without cancer and 418 patients with solid and hematological cancer recently diagnosed). MEASUREMENTS: Frailty was established according to the frailty phenotype. The frailty phenotype measures five components of frailty: weight loss, exhaustion, low physical activity, weakness and slow gait. Frailty phenotype was categorized as robust, pre-frail and frail. RESULTS: In a multinomial logistic regression, cancer, compared to the non-cancer group, is not associated with an increased likelihood of being classified as pre frail (RRR 0.9, 95% CI [0.5 ; 1.6 ], p 0.9) or frail (RRR 1.2, 95% CI [0.7 ; 2.0], p 0.4) rather than robust. When considering each Fried criterion, a significant higher odd of weight loss was observed in older patients with cancer compared to the non-cancer patients (OR 2.3, 95% CI [1.8; 3.0], p <0.001) but no statistically significant differences was found among the four other Fried criteria. Sensitivity analysis on the frailty index showed that cancer was not associated with a higher FI score compared to non-cancer (ß 0.002, 95%CI [-0.009; 0.01], p 0.6). CONCLUSION: In this real-life study evaluating elderly patients with and without cancer, we didn't confirm our hypothesis, in fact we found that cancer was not associated with frailty severity using both a phenotypic model and a deficit accumulation approach. Cancer may contribute, at least additively, to the development of frailty, like any other comorbidity, rather than a global underlying condition of vulnerability.

Gerontodermatology: the fragility of the epidermis in older adults.

The proportion of adults over 60 years of age is rapidly increasing and is estimated to reach approximately one-sixth of the global population by 2030. An ageing population is a real challenge for healthcare resources, including dermatologists and geriatricians, as age-related changes in skin integrity and barrier function make older adults more susceptible to developing skin pathologies such as pruritus, dermatitis and infections. Fragile skin arises from several interlinked causes, including age-related changes in skin barrier integrity, previous and current lifestyle choices, skin pathologies and medical interventions. Dermo-cosmetics can play a key role in enhancing skin care regimens and preventing pathologies in this age group. In vitro studies, clinical, and in-daily clinical practice studies of dermo-cosmetics have shown them to be effective in many skin conditions in older adults, like xerosis and pruritus. Incontinence-associated dermatitis (IAD), a common condition arising from contact with irritants such as urine and faeces which can significantly impact the quality of life of sufferers, can also be improved with a barrier cream in incontinent patients aged 70 years and older. This supplement focuses on the increased fragility of older skin, the development of common skin pathologies and the efficacy and tolerance of dermo-cosmetic products in older adults.

Comparison of management regimens following ultrasound diagnosis of nontubal ectopic pregnancies: a retrospective cohort study.

OBJECTIVE: To review management options for nontubal ectopic pregnancies. DESIGN: Retrospective cohort study. SETTING: Tertiary hospital in Melbourne, Australia. POPULATION: A total of 100 nontubal pregnancies: 1 abdominal, 32 caesarean scar, 14 cervical, 41 cornual-interstitial, 12 ovarian. METHODS: Cases were classified according to ectopic site. Management categories were medical, surgical, combination or expectant. Use of minimally invasive approaches (ultrasound-guided intra-sac injections or selective surgical techniques) was identified. Primary management was considered to be successful if no further unplanned interventions were required. MAIN OUTCOME MEASURES: Success of primary management and frequency of unplanned interventions. RESULTS: A high rate of success (82%) was demonstrated for all management regimens, with minimal morbidity and no deaths occurring. A high success rate was shown when the primary management regimen was systemic methotrexate or ultrasound-guided intra-sac injection (88%). The success rate for primary surgical management was 57%. High success rates were reported for both primary management with ultrasound-guided injections or in combination with systemic methotrexate (94%) and for primary management with systemic methotrexate alone (81%). Seventy-five per cent of women managed with minimally invasive surgical approaches avoided the need for more extensive surgery, but required longer follow up and additional interventions. CONCLUSION: Minimally invasive approaches were found to be safe and effective treatment for women desiring to conserve fertility. Ultrasound-guided intra-sac injection and laparoscopic ectopic removal procedures aimed at preserving reproductive organs should be included as minimally invasive primary management tools in addition to the well-recognised option of systemic methotrexate. TWEETABLE ABSTRACT: Nontubal ectopics: minimally invasive procedures a safe alternative to surgery in selected cases.

Is the 25-Hydroxy-Vitamin D Serum Concentration a Good Marker of Frailty?

INTRODUCTION: The phenotype proposed by Fried and colleagues is a widely used operational definition of frailty defining such state of extreme vulnerability of older persons. Low serum 25-hydroxy-vitamin D (25(OH)D) has been suggested as biomarker of frailty in literature. STUDY DESIGN: Cross-sectional. OBJECTIVES: To explore the association of 25(OH)D concentrations with the frailty phenotype and its criteria. METHODS: 321 subjects referred by their general practitioner to a geriatric frailty clinic were assessed between January 1, 2013 and September 23, 2013. Adjusted logistic regression models were performed between serum concentrations of 25(OH)D and the frailty phenotype (global score as well as its specific criteria). Receivers operating curves were established in order to explore the existence of a possible threshold of vitamin D levels highly predictive of frailty. RESULTS: Two hundred forty-one (75%) participants had 25(OH)D levels lower than 22 ng/ml. No significant association was reported between 25(OH)D levels and frailty. Among the five criteria of frailty, 25(OH)D was only associated with sedentariness (odds ratio 0.97 [95% confidence interval 0.95-0.99]). CONCLUSION: In our sample, no association was found between 25(OH)D levels and phenotype of frailty or the different frailty criterion except for sedentariness.

Visual Impairment Screening at the Geriatric Frailty Clinic for Assessment of Frailty and Prevention of Disability at the Gérontopôle.

OBJECTIVES: To evaluate visual performance and factors associated with abnormal vision in patients screened for frailty at the Geriatric Frailty Clinic (GFC) for Assessment of Frailty and Prevention of Disability at Toulouse University Hospital. DESIGN: Retrospective, observational cross-sectional, single-centre study. SETTING: Institutional practice. PARTICIPANTS: Patients were screened for frailty during a single-day hospital stay between October 2011 and October 2014 (n = 1648). MEASUREMENTS: Collected medical records included sociodemographic data (including living environment and educational level), anthropometric data, and clinical data. The general evaluation included the patient's functional status using the Activities of Daily Living (ADL) scale and the Instrumental Activity of Daily Living (IADL) scale, the Mini-Mental State Examination (MMSE) for cognition testing, and the Short Physical Performance Battery (SPPB) for physical performance. We also examined Body Mass Index (BMI), the Mini-Nutritional Assessment (MNA), and the Hearing Handicap Inventory for the Elderly Screening (HHIE-S) tool. The ophthalmologic evaluation included assessing visual acuity using the Snellen decimal chart for distant vision, and the Parinaud chart for near vision. Patients were divided into groups based on normal distant/near vision (NDV and NNV groups) and abnormal distant/near vision (ADV and ANV groups). Abnormal distant or near vision was defined as visual acuity inferior to 20/40 or superior to a Parinaud score of 2, in at least one eye. Associations with frailty-associated factors were evaluated in both groups. RESULTS: The mean age of the population was 82.6 ± 6.2 years. The gender distribution was 1,061 females (64.4%) and 587 males (35.6%). According to the Fried criteria, 619 patients (41.1%) were pre-frail and 771 (51.1%) were frail. Distant and near vision data were available for 1425 and 1426 patients, respectively. Distant vision was abnormal for 437 patients (30.7%). Near vision was abnormal for 199 patients (14%). Multiple regression analysis showed that abnormal distant vision as well as abnormal near vision were independently associated with greater age (P < 0.01), lower educational level (P < 0.05), lower performance on the MMSE (P < 0.001), and lower autonomy (P < 0.02), after controlling for age, gender, educational level, Fried criteria, and MMSE score. CONCLUSION: The high prevalence of visual disorders observed in the study population and their association with lower autonomy and cognitive impairment emphasises the need for systematic screening of visual impairments in the elderly. Frailty was not found to be independently associated with abnormal vision.

Body Composition and Anti-Neoplastic Treatment in Adult and Older Subjects - A Systematic Review.

BACKGROUND: The estimation of the risk of poor tolerance and overdose of antineoplastic agents protocols represents a major challenge in oncology, particularly in older patients. We hypothesize that age-related modifications of body composition (i.e. increased fat mass and decreased lean mass) may significantly affect tolerance to chemotherapy. METHOD: We conducted a systematic review for the last 25 years (between 1990 and 2015), using US National library of Medicine Medline electronic bibliographic database and Embase database of cohorts or clinical trials exploring (i) the interactions of body composition (assessed by Dual X-ray Absorptiometry, Bioelectrical Impedance Analyses, or Computerized Tomography) with pharmacokinetics parameters, (ii) the tolerance to chemotherapy, and (iii) the consequences of chemotherapies or targeted therapies on body composition. RESULTS: Our search identified 1504 articles. After a selection (using pre-established criteria) on titles and abstract, 24 original articles were selected with 3 domains of interest: impact of body composition on pharmacokinetics (7 articles), relationship between body composition and chemotoxicity (14 articles), and effect of anti-cancer chemotherapy on body composition (11 articles). The selected studies suggested that pharmacokinetic was influenced by lean mass, that lower lean mass could be correlated with toxicity, and that sarcopenic patients experienced more toxicities that non-sarcopenic patients. Regarding fat mass, results were less conclusive. No studies specifically explored the topic of body composition in older cancer patients. CONCLUSIONS: Plausible pathophysiological pathways linking body composition, toxicity, and pharmacokinetics are sustained by the actual review. However, despite the growing number of older cancer patients, our review highlighted the lack of specific studies in the field of anti-neoplastic agents toxicity regarding body composition conducted in elderly.

Methodological quality assessment of paper-based systematic reviews published in oral health.

OBJECTIVES: This study aimed to conduct a methodological assessment of paper-based systematic reviews (SR) published in oral health using a validated checklist. A secondary objective was to explore temporal trends on methodological quality. MATERIAL AND METHODS: Two electronic databases (OVID Medline and OVID EMBASE) were searched for paper-based SR of interventions published in oral health from inception to October 2014. Manual searches of the reference lists of paper-based SR were also conducted. Methodological quality of included paper-based SR was assessed using an 11-item questionnaire, Assessment of Multiple Systematic Reviews (AMSTAR) checklist. Methodological quality was summarized using the median and inter-quartile range (IQR) of the AMSTAR score over different categories and time periods. RESULTS: A total of 643 paper-based SR were included. The overall median AMSTAR score was 4 (IQR 2-6). The highest median score (5) was found in the pain dentistry and periodontology fields, while the lowest median score (3) was found in implant dentistry, restorative dentistry, oral medicine, and prosthodontics. The number of paper-based SR per year and the median AMSTAR score increased over time (median score in 1990s was 2 (IQR 2-3), 2000s was 4 (IQR 2-5), and 2010 onwards was 5 (IQR 3-6)). CONCLUSION: Although the methodological quality of paper-based SR published in oral health has improved in the last few years, there is still scope for improving quality in most evaluated dental specialties. CLINICAL RELEVANCE: Large-scale assessment of methodological quality of dental SR highlights areas of methodological strengths and weaknesses that can be targeted in future publications to encourage better quality review methodology.

The expression of PD-L1 APE1 and P53 in hepatocellular carcinoma and its relationship to clinical pathology.

OBJECTIVE: To study the expression of programmed death-ligand1 (PD-L1) in hepatocellular carcinoma and its relationship with clinicopathological characteristics and, prognosis of hepatocellular carcinoma and APE1, P53 protein expression levels. PATIENTS AND METHODS: A total of 128 patients with hepatocellular carcinoma were enrolled in this study. The expression of PD-L1, APE1 and P53 were detected by immunohistochemistry.Use immunohistochemical ABC staining method to detect the expression levels of PD-L1, APE1 and P53 protein in the hepatocellular carcinoma of 128 cases. RESULTS: Positive The positive expression rates levels of PD-L1, APE1, and P53 protein in hepatocellular carcinoma tissues are were 82.03%, 92.19%, and 60.94%. PD-L1 positive expression were significantly associated with clinical stage, The PD-L1 protein has a high expression in patients with I ~ II stage liver cancerHBV infection positive and nonportal vein thrombosis (p=0.041; p=0.030; p=0.014). It is inversely correlated with P53 and PD-L1 expression (correlation coefficient -0.227, p=0.010), and positively correlated with APE1 expression (correlation coefficient 0.189, p=0.032). The expression of PD-L1 is associated with the survival time of patients with hepatocellular carcinoma, and the median survival time of patients with high expression of PD-L1 is ten months. The median survival time of patients with low expression is five months (p=0.001). The relationship between the expression of APE1 and P53 protein and overall survival time of patients with hepatocellular carcinoma has not been found. CONCLUSIONS: The PD-L1 and APE1 expression in hepatocellular carcinoma are related to the level of the expression of P53 protein. The expression state of PD-L1 may be a prognostic factor in hepatocellular carcinoma.

Validation of the Mini Nutritional Assessment-Short Form in a Population of Frail Elders without Disability. Analysis of the Toulouse Frailty Platform Population in 2013.

OBJECTIVE: To assess the validity of the Mini Nutritional Assessment-Short Form (MNA-SF) in elderly patients from the Toulouse Frailty Platform. PARTICIPANTS: Overall, 267 patients aged 65 and over, without severe cognitive impairment (i.e. Mini Mental Status Examination > 20 and CDR<1), no physical disability (i.e. Activities of Daily Living ≥ 5) and no active cancer history (over the past 12 months) were included in 2013. MEASUREMENTS: Receiver operating characteristic (ROC) analyses were used to assess the predictive validity of the French version of the MNA-SF for good nutritional status (defined as a full MNA score≥24/30). Analyses were conducted in the overall sample and then in subgroups of frail and pre-frail subjects according to the frailty phenotype. Optimal cut-off points were determined to obtain the best sensitivity/specificity ratio and the highest number of correctly classified subjects. RESULTS: Among 267 patients, mean age=81.5±5.8; women=67.0%; 138 (51.7%) were frail, 98 (36.7%) were pre-frail and 31 (11.6%) were robust. Given their MNA-SF scores, 201 (75.3%) had a good nutritional status, 61 (22.8%) were at risk of malnutrition and 5 (1.9%) were malnourished. In the overall sample, but also in subgroups of pre-frail or frail elders, the areas under ROC curves were 0.954, 0.948 and 0.958 respectively. The 11 points cut-off provided the best correct classification ratio (91.4%); sensitivity=94.0%, specificity=83.3%. CONCLUSION: The MNA-SF appeared to be a validated and effective tool for malnutrition screening in frail elders. Implementing this tool in clinical routine should contribute to improving the screening of malnourished frail individuals.

Description of 1,108 older patients referred by their physician to the "Geriatric Frailty Clinic (G.F.C) for Assessment of Frailty and Prevention of Disability" at the gerontopole.

INTRODUCTION: Frailty is considered as an early stage of disability which, differently from disability, is still amenable for preventive interventions and is reversible. In 2011, the "Geriatric Frailty Clinic (G.F.C) for Assessment of Frailty and Prevention of Disability" was created in Toulouse, France, in association with the University Department of General Medicine and the Midi-Pyrénées Regional Health Authority. This structure aims to support the comprehensive and multidisciplinary assessment of frail older persons, to identify the specific causes of frailty and to design a personalized preventive plan of intervention against disability. In the present paper, we describe the G.F.C structure, organization, details of the global evaluation and preventive interventions against disability, and provide the main characteristics of the first 1,108 patients evaluated during the first two years of operation. METHODS: Persons aged 65 years and older, considered as frail by their physician (general practitioner, geriatrician or specialist) in the Toulouse area, are invited to undergo a multidisciplinary evaluation at the G.F.C. Here, the individual is assessed in order to detect the potential causes for frailty and/or disability. At the end of the comprehensive evaluation, the team members propose to the patient (in agreement with the general practitioner) a Personalized Prevention Plan (PPP) specifically tailored to his/her needs and resources. The G.F.C also provides the patient's follow-up in close connection with family physicians. RESULTS: Mean age of our population was 82.9 ± 6.1 years. Most patients were women (n=686, 61.9%). According to the Fried criteria, 423 patients (39.1%) were pre-frail, and 590 (54.5%) frail. Mean ADL (Activities of Daily Living) score was 5.5 ± 1.0. Consistently, IADL (Instrumental ADL) showed a mean score of 5.6 ± 2.4. The mean gait speed was 0.78 ± 0.27 and 25.6% (272) of patients had a SPPB (Short Physical Performance Battery) score equal to or higher than 10. Dementia was observed in 14.9% (111) of the G.F.C population according to the CDR scale (CDR ≥2). Eight percent (84) presented an objective state of protein-energy malnutrition with MNA (Mini Nutritional Assessment) score < 17 and 39.5% (414) were at risk of malnutrition (MNA=17-23.5). Concerning PPP, for 54.6% (603) of patients, we found at least one medical condition which needed a new intervention and for 32.8% (362) substantial therapeutic changes were recommended. A nutritional intervention was proposed for 61.8% (683) of patients, a physical activity intervention for 56.7% (624) and a social intervention for 25.7% (284). At the time of analysis, a one-year reassessment had been carried out for 139 (26.7%) of patients. CONCLUSIONS: The G.F.C was developed to move geriatric medicine to frailty, an earlier stage of disability still reversible. Its particularity is that it is intended for a single target population that really needs preventive measures: the frail elderly screened by physicians. The screening undergone by physicians was really effective because 93.6% of the subjects who referred to this structure were frail or pre-frail according to Fried's classification and needed different medical interventions. The creation of units like the G.F.C, specialized in evaluation, management and prevention of disability in frail population, could be an interesting option to support general practitioners, promote the quality of life of older people and increase life expectancy without disability.

MAPT STUDY: A MULTIDOMAIN APPROACH FOR PREVENTING ALZHEIMER'S DISEASE: DESIGN AND BASELINE DATA.

OBJECTIVE: The Multidomain Alzheimer Preventive Trial (MAPT study) was designed to assess the efficacy of isolated supplementation with omega-3 fatty acid, an isolated multidomain intervention (consisting of nutritional counseling, physical exercise, cognitive stimulation) or a combination of the two interventions on the change of cognitive functions in frail subjects aged 70 years and older for a period of 3 years. Ancillary neuroimaging studies were additionally implemented to evaluate the impact of interventions on cerebral metabolism (FDG PET scans) and atrophy rate (MRIs), as well as brain amyloïd deposit (AV45 PET scans). DESIGN PATIENTS: 1680 subjects (mean age: 75.3 years; female: 64.8 %), enrolled by 13 memory clinics, were randomized into one of the following four groups: omega-3 supplementation alone, multidomain intervention alone, omega-3 plus multidomain intervention, or placebo. Participants underwent cognitive, functional and biological assessments at M6, M12, M24 and M36 visits. The primary endpoint is a change of memory function at 3 years, as assessed by the Free and Cued Selective Reminding test. All participants will be followed for 2 additional years after the 3-years intervention (MAPT PLUS extension study). INTERVENTIONS: 1/Omega-3 supplementation: two soft capsules daily as a single dose, containing a total of 400 mg docosahexaenoic acid (DHA), i.e., 800 mg docosahexaenoic acid per day, for 3 years. 2/ Multidomain intervention: collective training sessions conducted in small groups (6-8 participants) in twelve 120-minute sessions over the first 2 months (two sessions a week for the first month, and one session a week the second month) then a 60-minute session per month in the following three areas: nutrition, physical activity, and cognition until the end of the 3 years. In addition to the collective sessions, individualized preventive outpatient visits exploring possible risk factors for cognitive decline are performed at baseline, M12 and M24. BASELINE POPULATION: For cognition, the mean MMSE at baseline was 28.1 (± 1.6). About 58% and 42% of participants had a CDR score equal to 0 and 0.5, respectively. Regarding mobility status, 200 (11.9%) had a 4-m gait speed lower or equal to 0.8 m/s. According to the Fried criteria, 673 (42.1%) participants were considered pre frail, and 51 (3.2%) frail. The red blood cell DHA content was 26.1 ± 8.1 µg/g. Five hundred and three participants underwent baseline MRI. AV45 PET scans were performed in 271 individuals and preliminary results showed that 38.0% had a cortical SUVR > 1.17, which gave an indication of significant brain amyloïd deposit. DISCUSSION: The MAPT trial is presently the first largest and longest multidomain preventive trial relevant to cognitive decline in older adults with subjective memory complaints. The multidomain intervention designed for the MAPT trial is likely to be easily implemented within the general population.

Cognitive frailty: rational and definition from an (I.A.N.A./I.A.G.G.) international consensus group.

The frailty syndrome has recently attracted attention of the scientific community and public health organizations as precursor and contributor of age-related conditions (particularly disability) in older persons. In parallel, dementia and cognitive disorders also represent major healthcare and social priorities. Although physical frailty and cognitive impairment have shown to be related in epidemiological studies, their pathophysiological mechanisms have been usually studied separately. An International Consensus Group on "Cognitive Frailty" was organized by the International Academy on Nutrition and Aging (I.A.N.A) and the International Association of Gerontology and Geriatrics (I.A.G.G) on April 16th, 2013 in Toulouse (France). The present report describes the results of the Consensus Group and provides the first definition of a "Cognitive Frailty" condition in older adults. Specific aim of this approach was to facilitate the design of future personalized preventive interventions in older persons. Finally, the Group discussed the use of multidomain interventions focused on the physical, nutritional, cognitive and psychological domains for improving the well-being and quality of life in the elderly. The consensus panel proposed the identification of the so-called "cognitive frailty" as an heterogeneous clinical manifestation characterized by the simultaneous presence of both physical frailty and cognitive impairment. In particular, the key factors defining such a condition include: 1) presence of physical frailty and cognitive impairment (CDR=0.5); and 2) exclusion of concurrent AD dementia or other dementias. Under different circumstances, cognitive frailty may represent a precursor of neurodegenerative processes. A potential for reversibility may also characterize this entity. A psychological component of the condition is evident and concurs at increasing the vulnerability of the individual to stressors.

Designing pharmaceutical trials for sarcopenia in frail older adults: EU/US Task Force recommendations.

An international task force of academic and industry leaders in sarcopenia research met on December 5, 2012 in Orlando, Florida to develop guidelines for designing and executing randomized clinical trials of sarcopenia treatments. The Task Force reviewed results from previous trials in related disease areas to extract lessons relevant to future sarcopenia trials, including practical issues regarding the design and conduct of trials in elderly populations, the definition of appropriate target populations, and the selection of screening tools, outcome measures, and biomarkers. They discussed regulatory issues, the challenges posed by trials of different types of interventions, and the need for standardization and harmonization. The Task Force concluded with recommendations for advancing the field toward better clinical trials.

Looking for frailty in community-dwelling older persons: the Gérontopôle Frailty Screening Tool (GFST).

The frailty syndrome is a pre-disability condition suitable to be targeted by preventive interventions against disability. In order to identify frail older persons at risk of negative outcomes, general practitioners must be provided with an easy and quick screening tool for detecting frailty without special effort. In the present paper, we present the screening tool for frailty that the Gérontopôle of Toulouse (France) has developed and implemented in primary care in the region with the collaboration of the Department of Family Medicine of the University of Toulouse. The Gérontopôle Frailty Screening Tool (GFST) is designed to be administered to persons aged ≥65 years with no physical disability and acute clinical disease. It is composed by an initial questionnaire aimed at attracting the general practitioner's attention to very general signs and/or symptoms suggesting the presence of an underlying frailty status. Then, in a second section, the general practitioner expresses his/her own view about the frailty status of the individual. The clinical judgment of the general practitioner is finally retained for determining the eventual presence of frailty. Preliminary data document that almost everyone (95.2%) of the 442 patients referred to the Gérontopôle frailty clinic by general practitioners using the GFST indeed presents a condition of (pre-)frailty according to the criteria proposed by Fried and colleagues in the Cardiovascular Health Study. The use of the GFST may help at raising awareness about the importance of identifying frailty, training healthcare professionals at the detection of the syndrome, and developing preventive interventions against disabling conditions.

Frailty consensus: a call to action.

Frailty is a clinical state in which there is an increase in an individual's vulnerability for developing increased dependency and/or mortality when exposed to a stressor. Frailty can occur as the result of a range of diseases and medical conditions. A consensus group consisting of delegates from 6 major international, European, and US societies created 4 major consensus points on a specific form of frailty: physical frailty. 1. Physical frailty is an important medical syndrome. The group defined physical frailty as "a medical syndrome with multiple causes and contributors that is characterized by diminished strength, endurance, and reduced physiologic function that increases an individual's vulnerability for developing increased dependency and/or death." 2. Physical frailty can potentially be prevented or treated with specific modalities, such as exercise, protein-calorie supplementation, vitamin D, and reduction of polypharmacy. 3. Simple, rapid screening tests have been developed and validated, such as the simple FRAIL scale, to allow physicians to objectively recognize frail persons. 4. For the purposes of optimally managing individuals with physical frailty, all persons older than 70 years and all individuals with significant weight loss (>5%) due to chronic disease should be screened for frailty.

Vitamin D supplementation in older adults: searching for specific guidelines in nursing homes.

BACKGROUND: The prevalence of vitamin D insufficiency is very high in the nursing home (NH) population. Paradoxically, vitamin D insufficiency is rarely treated despite of strong clinical evidence and recommendations for supplementation. This review aims at reporting the current knowledge of vitamin D supplementation in NH and proposing recommendations adapted to the specificities of this institutional setting. DESIGN: Current literature on vitamin D supplementation for NH residents was narratively presented and discussed by the French Group of Geriatrics and Nutrition. RESULT: Vitamin D supplementation is a safe and well-tolerated treatment. Most residents in NH have vitamin D insufficiency, and would benefit from vitamin D supplement. However, only few residents are actually treated. Current specific and personalized protocols for vitamin D supplementation may not be practical for use in NH settings (e.g., assessment of serum vitamin D concentrations before and after supplementation). Therefore, our group proposes a model of intervention based on the systematic supplementation of vitamin D (1,000 IU/day) since the patient's admission to the NH and throughout his/her stay without the need of a preliminary evaluation of the baseline levels. Calcium should be prescribed only in case of poor dietary calcium intake. CONCLUSION: A population-based rather than individual-based approach may probably improve the management of vitamin D insufficiency in the older population living in NH, without increasing the risks of adverse health problems. The clinical relevance and cost effectiveness of this proposal should be assessed under NH real-world conditions to establish its feasibility.

Dietary vitamin D intake and muscle mass in older women. Results from a cross-sectional analysis of the EPIDOS study.

OBJECTIVES: Vitamin D intake may prevent physical performance decline through prevention of muscle mass loss. Our objective was to determine whether low dietary intakes were associated with low muscle mass (MM). DESIGN AND PARTICIPANTS: Cross-sectional analysis of 1989 community-dwelling women (mean age 80.5±3.8years) from the EPIDémiologie de l'OStéoporose (EPIDOS) study were assessed at baseline. MEASUREMENTS: Low intakes of vitamin D (<70µg/week) were estimated from the weekly dietary vitamin D intakes (self-administered food frequency questionnaire). Low MM was defined according to the appendicular skeletal muscle mass index assessed using Dual Energy X-ray Absorptiometry, divided by square height of less than 5.45 kg/m2. Usual gait speed defined physical performance. Age, sun exposure, co-morbidities, education level, living arrangements, recreational physical activity, dietary protein and calcium intakes, bone mineral density, handgrip strength, and body mass index were considered as potential confounders. Multivariate logistic regression analyses assessed the association between low vitamin D intakes and low MM. RESULTS: Two-hundred and nine (10.5%) women with low MM were compared to 1,780 women with normal MM. In final model, obesity/overweight (Adjusted Odds Ratios, aOR=0.09; 95%CI [0.05-0.17]), malnutrition (aOR=3.90; 95%CI [2.74-5.54]) and low handgrip strength (aOR=2.33; 95%CI [1.44-3.77]; p<0.001) were statistically associated with a low MM status. CONCLUSION: No association with low MM has been reported regarding low dietary intakes of vitamin D.
