Use of dried blood spots for monitoring inflammatory and nutritional biomarkers in the elderly.

OBJECTIVES: Blood microsampling, particularly dried blood spots (DBSs), is an attractive minimally-invasive approach that is well suited for home sampling and predictive medicine associated with longitudinal follow-up of the elderly. However, in vitro diagnostic quantification of biomarkers from DBS poses a major challenge. Clinical mass spectrometry can reliably quantify blood proteins in various research projects. Our goal here was to use mass spectrometry of DBS in a real-world clinical setting and compared it to the standard immunoassay method. We also sought to correlate DBS mass spectrometry measurements with clinical indices. METHODS: A clinical trial of diagnostic equivalence was conducted to compare conventional venous samples quantified by immunoassay and DBSs quantified by mass spectrometry in an elderly population. We assayed three protein biomarkers of nutritional and inflammatory status: prealbumin (transthyretin), C-reactive protein, and transferrin. RESULTS: The analysis of DBSs showed satisfactory variability and low detection limits. Statistical analysis confirmed that the two methods give comparable results at clinical levels of accuracy. In conclusion, we demonstrated, in a real-life setting, that DBSs can be used to measure prealbumin, CRP and transferrin, which are commonly used markers of nutritional status and inflammation in the elderly. However, there was no correlation with patient frailty for these proteins. CONCLUSIONS: Early detection and regular monitoring of nutritional and inflammatory problems using DBS appear to be clinically feasible. This could help resolve major public health challenges in the elderly for whom frailty leads to serious risks of health complications.

New Perspectives of Multiplex Mass Spectrometry Blood Protein Quantification on Microsamples in Biological Monitoring of Elderly Patients.

Blood microsampling combined with large panels of clinically relevant tests are of major interest for the development of home sampling and predictive medicine. The aim of the study was to demonstrate the practicality and medical utility of microsamples quantification using mass spectrometry (MS) in a clinical setting by comparing two types of microsamples for multiplex MS protein detection. In a clinical trial based on elderly population, we compared 2 µL of plasma to dried blood spot (DBS) with a clinical quantitative multiplex MS approach. The analysis of the microsamples allowed the quantification of 62 proteins with satisfactory analytical performances. A total of 48 proteins were significantly correlated between microsampling plasma and DBS (p < 0.0001). The quantification of 62 blood proteins allowed us to stratify patients according to their pathophysiological status. Apolipoproteins D and E were the best biomarker link to IADL (instrumental activities of daily living) score in microsampling plasma as well as in DBS. It is, thus, possible to detect multiple blood proteins from micro-samples in compliance with clinical requirements and this allows, for example, to monitor the nutritional or inflammatory status of patients. The implementation of this type of analysis opens new perspectives in the field of diagnosis, monitoring and risk assessment for personalized medicine approaches.

COVID-19 Outbreaks in Nursing Homes Despite Full Vaccination with BNT162b2 of a Majority of Residents.

BACKGROUND: It is not known if widespread vaccination can prevent the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in subpopulations at high risk, like older adults in nursing homes (NH). OBJECTIVE: The objective of the study was to know if coronavirus disease 2019 (COVID-19) outbreaks can occur in NH with high vaccination coverage among its residents. METHODS: We identified, using national professional networks, NH that suffered COVID-19 outbreaks despite having completed a vaccination campaign, and asked them to send data, using predefined collecting forms, on the number of residents exposed, their vaccination status and the number, characteristics, and evolution of patients infected. The main outcome was to identify outbreaks occurring in NH with high vaccine coverage. Secondary outcomes were residents' risk of being infected, developing severe disease, or dying from COVID-19 during the outbreak. SARS-CoV-2 infection was defined by a positive reverse transcriptase-polymerase chain reaction. All residents were serially tested whenever cases appeared in a facility. Unadjusted secondary attack rates, relative risks, and vaccine effectiveness during the outbreak were estimated. RESULTS: We identified 31 NH suffering an outbreak during March-April 2021, of which 27 sent data, cumulating 1,768 residents (mean age 88.4, 73.4% women, 78.2% fully vaccinated). BNT162b2 was the vaccine employed in all NH. There were 365 cases of SARS-CoV-2 infection. Median secondary attack rates were 20.0% (IQR 4.4%-50.0%) among unvaccinated residents and 16.7% (IQR 9.5%-29.2%) among fully vaccinated ones. Severe cases developed in 42 of 80 (52.5%) unvaccinated patients, compared with 56 of 248 (22.6%) fully vaccinated ones (relative risks [RR] 4.17, 95% CI: 2.43-7.17). Twenty of the unvaccinated patients (25.0%) and 16 of fully vaccinated ones (6.5%) died from COVID-19 (RR 5.11, 95% CI: 2.49-10.5). Estimated vaccine effectiveness during the outbreak was 34.5% (95% CI: 18.5-47.3) for preventing SARS-CoV-2 infection, 71.8% (58.8-80.7) for preventing severe disease, and 83.1% (67.8-91.1) for preventing death. CONCLUSIONS: Outbreaks of COVID-19, including severe cases and deaths, can still occur in NH despite full vaccination of a majority of residents. Vaccine remains highly effective, however, for preventing severe disease and death. Prevention and control measures for SARS-CoV-2 should be maintained in NH at periods of high incidence in the community.

National survey on the management of heart failure in individuals over 80 years of age in French geriatric care units.

BACKGROUND: To evaluate the prevalence and management of heart failure (HF) in very old patients in geriatric settings. METHODS: Members of the French Society of Geriatrics and Gerontology throughout France were invited to participate in a point prevalence survey and to include all patients ≥80 years old, hospitalized in geriatric settings, with HF (stable or decompensated) on June 18, 2012. General characteristics, presence of comorbidities, blood tests and medications were recorded. RESULTS: Among 7,197 patients in geriatric institution, prevalence of HF was 20.5% (n = 1,478): (27% in acute care, 24.2% in rehabilitation care and 18% in nursing home). Mean age was 88.2 (SD = 5.2) and Charlson co morbidity score was high (8.49 (SD = 2.21)). Left ventricular ejection fraction (LVEF) was available in 770 (52%) patients: 536 (69.6%) had a preserved LVEF (≥ 50%), 120 (15.6%) a reduced LVEF (< 40%), and 114 (14.8%) a midrange LVEF (40-49%). Prescription of recommended HF drugs was low: 42.6% (629) used Angiotensin Converting Enzyme Inhibitors (ACEI) or Angiotensin Receptor Blockers (ARBs), 48.0% (709) ß-blockers, and 21.9% (324) ACEI or ARB with ß-blockers, even in reduced LVEF. In multivariate analysis ACEI or ARBs were more often used in patients with myocardial infarction (1.36 (1.04-1.78)), stroke (1.42 (1.06-1.91)), and diabetes (1.54 (1.14-2.06)). ß blockers were more likely used in patients with myocardial infarction (2.06 (1.54-2.76)) and atrial fibrillation (1.70 (1.28-2.28)). CONCLUSION: In this large very old population, prevalence of HF was high. Recommended HF drugs were underused even in reduced LVEF. These results indicate that management of HF in geriatric settings can still be improved.

Dietary scores at midlife and healthy ageing in a French prospective cohort.

Although nutrition has been advocated as a major determinant of healthy ageing (HA), studies investigating the link between dietary quality and HA are scarce. We investigated the association between adherence to French food-based and nutrient-based guidelines at midlife, as assessed by three dietary scores, and HA. HA was assessed in 2007-2009, among 2329 participants of the SUpplémentation en Vitamines et Minéraux AntioXydants study aged 45-60 years at baseline (1994-1995) and initially free of diabetes, CVD and cancer. HA was defined as not developing any major chronic disease, good physical and cognitive functioning, no limitations in instrumental activities of daily living, no depressive symptoms, no health-related limitations in social life, good overall self-perceived health and no function-limiting pain. Data from repeated 24-h dietary records provided at baseline permitted the computation of the modified French Programme National Nutrition Santé-Guideline Score (mPNNS-GS), the Probability of Adequate Nutrient Intake Dietary Score (PANDiet) and the Diet Quality Index-International (DQI-I). Associations of these scores with HA were assessed by logistic regression. In 2007-2009, 42 % of men and 36 % of women met our criteria of HA. After adjustment for potential confounders, higher scores of the mPNNS-GS (ORquartile 4 v. quartile 1 1·44; 95 % CI 1·10, 1·87; P trend=0·006) and the PANDiet (1·28; 95 % CI 1·00, 1·64; P trend=0·03) were associated with higher odds of HA. We observed no association between DQI-I and HA. In conclusion, this study suggests a beneficial long-term role of high adherence to both food-based and nutrient-based French dietary guidelines for a HA process.

Healthy Aging 5 Years After a Period of Daily Supplementation With Antioxidant Nutrients: A Post Hoc Analysis of the French Randomized Trial SU.VI.MAX.

This study's objective was to investigate healthy aging in older French adults 5 years after a period of daily nutritional-dose supplementation with antioxidant nutrients. The study was based on the double-blind, randomized trial, Supplementation with Antioxidant Vitamins and Minerals (SU.VI.MAX) Study (1994-2002) and the SU.VI.MAX 2 Follow-up Study (2007-2009). During 1994-2002, participants received a daily combination of vitamin C (120 mg), ß-carotene (6 mg), vitamin E (30 mg), selenium (100 µg), and zinc (20 mg) or placebo. Healthy aging was assessed in 2007-2009 by using multiple criteria, including the absence of major chronic disease and good physical and cognitive functioning. Data from a subsample of the SU.VI.MAX 2 cohort, initially free of major chronic disease, with a mean age of 65.3 years in 2007-2009 (n = 3,966), were used to calculate relative risks. Supplementation was associated with a greater healthy aging probability among men (relative risk = 1.16, 95% confidence interval: 1.04, 1.29) but not among women (relative risk = 0.98, 95% confidence interval: 0.86, 1.11) or all participants (relative risk = 1.07, 95% confidence interval: 0.99, 1.16). Moreover, exploratory subgroup analyses indicated effect modification by initial serum concentrations of zinc and vitamin C. In conclusion, an adequate supply of antioxidant nutrients (equivalent to quantities provided by a balanced diet rich in fruits and vegetables) may have a beneficial role for healthy aging.

A Healthy Dietary Pattern at Midlife, Combined with a Regulated Energy Intake, Is Related to Increased Odds for Healthy Aging.

BACKGROUND: Few studies have investigated the long-term impact of overall dietary patterns (DPs) on healthy aging (HA), and current findings are inconsistent. OBJECTIVE: Our study's objective was to investigate the association between empirically derived DPs in midlife and HA after 13 y of follow-up. METHODS: Baseline dietary data from repeated 24-h dietary records (on average, 10 records per participant) of a subsample of the SU.VI.MAX (SUpplémentation en Vitamines et Minéraux AntioXydants) study allowed extraction of 2 DPs with the use of principal components analysis on 37 food groups. HA was assessed in 2007-2009 among 2796 participants of the SU.VI.MAX study aged 45-60 y at baseline (1994-1995), who were initially free of diabetes, cardiovascular disease, and cancer. HA was defined as not developing any major chronic disease, good physical and cognitive functioning, no limitations in instrumental activities of daily living, no depressive symptoms, no health-related limitations in social life, good overall self-perceived health, and no function-limiting pain. The association between DPs (in tertiles) and HA was evaluated by using multivariable logistic regression, and a potential interaction with energy intake was investigated. RESULTS: A "Western" and a "healthy" DP were identified. After adjustment for a large number of potential confounders, there was no significant association between the Western DP and HA. Moreover, the healthy pattern was not associated with HA among subjects with high (i.e., greater than or equal to the median) energy intake. Among subjects with low (i.e., less than the median) energy intake, on the other hand, higher scores on the healthy DP were related to higher odds of HA (OR for tertile 3 vs. tertile 1: 1.49; 95% CI: 1.11, 2.00; P-trend = 0.01). CONCLUSION: Adherence to a healthy diet in midlife that provides micronutrients, fiber, and antioxidants while regulating energy intake may help to promote HA.

Estimation of age- and comorbidities-adjusted percentiles of high-sensitivity cardiac troponin T levels in the elderly.

BACKGROUND: Cardiac troponin level measured by high-sensitivity assays (hs-cTn) in the elderly is frequently found higher than the 99th percentile upper reference limit, making the diagnosis of acute coronary syndromes (ACS) difficult. This study aimed at: 1) identifying determinants of hs-cTnT levels in an unselected population of elderly subjects; and 2) assessing the prognosis value of increased hs-cTnT in elderly people free of ACS. METHODS: Hs-cTnT was measured in 591 individuals aged over 65 years without suspicion of ACS. Comorbidities were assessed using the Cumulative Illness Rating Scale for Geriatrics (CIRS-G). C-reactive protein, α1-acid glycoprotein, albumin and creatinine were measured. Factors influencing hs-cTnT levels were assessed through linear regression and quantile regression was used to model percentiles of hs-cTnT. Risk of mortality was assessed through Cox regression. RESULTS: Age, gender, cardiac CIRS-G, estimated glomerular filtration rate (p<0.001 for all), albumin (p<0.028) and α1-acid glycoprotein (p=0.002) were independent predictors of hs-cTnT. After exclusion of outliers, the median was 15 ng/L and 99th percentile was 64 ng/L. After controlling for comorbidities, the 99th percentile increased from 24 ng/L at age 65 to 53 ng/L at age 90 in females and from 33 ng/L to 75 ng/L in males. In multivariate analysis, hs-cTnT level was significantly related to mortality. CONCLUSIONS: Hs-cTnT level is associated with inflammation and renal function in the elderly. Independently of comorbidities, hs-cTnT concentration increases exponentially with age after 65 years. Decision limits adapted to age and sex may be useful to patient management.

[Pleasure and aging in the elderly]. / Plaisir et vieillissement chez les plus de 65 ans.

A survey carried out of people aged 65 and over aimed to provide a clearer picture of the older population's relationship with pleasure. How do they feel as they age? Do they still find pleasure in things? In what ways? If there a certain self-censorship among the older population with regard to the subject? Or, on the contrary, do they make the most out of life without any complexes or limits? A sample of people aged between 15 and 64 were also surveyed for their opinion on the following questions: do they feel that older people still find pleasure in things? How do senior citizens enjoy themselves today?

Carotenoid-rich dietary patterns during midlife and subsequent cognitive function.

Carotenoids may help to prevent the ageing of the brain. Previous findings regarding ß-carotene alone are not consistent. In the present study, we evaluated the cross-time association between a carotenoid-rich dietary pattern (CDP) and subsequent cognitive performance using a sample of 2983 middle-aged adults participating in the SU.VI.MAX (Supplémentation en Vitamines et Minéraux Antioxydants) study. Cognitive performance was assessed in 2007-9 using six neuropsychological tests, and a composite cognitive score was computed. The cognitive data were related to dietary data obtained by repeated 24 h dietary records (1994-6) and to measurements of baseline plasma concentrations of carotenoids (lutein, zeaxanthin, ß-cryptoxanthin, lycopene, α-carotene, trans-ß-carotene and cis-ß-carotene). DP were extracted using the reduced rank regression method for 381 participants and then extrapolated to the whole sample using plasma carotenoid concentrations as response variables. Associations between a CDP and cognitive function measured 13 years later were estimated with ANCOVA providing mean difference values and 95 % CI across the tertiles of CDP. A correlation between CDP and consumption of orange- and green-coloured fruits and vegetables, vegetable oils and soup was observed. CDP was found to be associated with a higher composite cognitive score (mean difference 1·04, 95 % CI 0·20, 1·87, P for trend 0·02), after adjustment for sociodemographic, lifestyle and health factors. Similar findings were obtained for scores obtained in the cued recall task, backward digit span task, trail making test and semantic fluency task (all P for trend < 0·05). Further studies ought to confirm whether a diet providing sufficient quantity and variety of coloured fruits and vegetables may contribute to the preservation of cognitive function during ageing.

Intake of specific nutrients and foods and hearing level measured 13 years later.

Only a few studies have investigated the impact of nutrients and food groups on hearing level (HL) with a population-based approach. We examined the 13-year association between intake of specific nutrients and food groups and HL in a sample of French adults. A total of 1823 subjects, aged 45-60 years at baseline, participating in the Supplementation with Antioxidant Vitamins and Minerals 2 cohort were selected. Nutrient and food intake was estimated at baseline among participants who had completed at least six 24 h dietary records. HL was assessed 13 years after baseline and was defined as the pure-tone air conduction of the worse ear at the following thresholds: 0·5, 1, 2 and 4 kHz. The relationship between quartiles of energy-adjusted nutrient and food intake and HL was assessed by multivariate linear regression analyses, in men and women separately. Intakes of retinol (P-trend » 0·058) and vitamin B12 (P-trend=0·068) tended to be associated with better HL in women. Intakes of meat as a whole (P-trend=0·030), red meat (P-trend=0·014) and organ meat (P-trend=0·017) were associated with better HL in women. Higher intake of seafood as a whole (P-trend=0·07) and of shellfish (P-trend=0·097) tended to be associated with better HL in men. Consumption of meat is therefore associated with a better HL in women. Further research is required to better elucidate the mechanisms behind the associations between diet and hearing.

Multimorbidity patterns and subgroups among autistic adults with intellectual disability: Results from the EFAAR study.

LAY ABSTRACT: Multimorbidity relates to having multiple chronic health conditions. It is a risk factor for poor health and reduces life expectancy. Autistic people have multiple chronic health conditions and die prematurely, especially if they have an intellectual disability (autism spectrum disorder and intellectual disability). Certain pathophysiological processes observed in autism spectrum disorder are common to those related to the genesis and/or maintenance of multimorbidity. Furthermore, multimorbidity could be helpful in better identifying patient subgroups in autism spectrum disorder. It is therefore essential to better characterize multimorbidity and its consequences in the subgroup of autism spectrum disorder + intellectual disability individuals to offer them personalized care. We conducted a preliminary study of 63 autism spectrum disorder + intellectual disability adults to classify them according to their multimorbidity and search for a specific combination of chronic health conditions. We observed high and early multimorbidity in this sample and identified four classes of participants, distinguished by their multimorbidity status, independence and number of treatments. In addition, we observed a dominant combination of multimorbidity in our sample, combining immune dysfunction and gastrointestinal disorders, neurological and joint diseases. These findings support the hypothesis that an altered gut-brain relationship is involved in the risk of autism spectrum disorder, its outcome, and its association with chronic health conditions. Although larger studies are needed, our results suggest that subgroups of autism spectrum disorder + intellectual disability individuals can be identified based on their multimorbidity and potentially different ageing trajectories. A more comprehensive and personalized approach is needed to reduce the burden of multimorbidity and increase the quality of life and life expectancy in autism spectrum disorder/ intellectual disability.

[Knowledge and application of the HAS recommendations concerning the diagnosis of undernutrition in people aged 70 and above: an international online survey among members of the "Société Française de Gériatrie et de Gérontologie"]. / Connaissances et application des recommandations HAS concernant le diagnostic de la dénutrition chez la personne de 70 ans et plus : une enquête menée en ligne auprès des membres de la Société française de gériatrie et de gérontologie.

OBJECTIVES: To assess the knowledge and the use in clinical practice of the "French National Authority for Health" (HAS) 2021 recommendations on the diagnosis of malnutrition in older adults aged 70 years and above. METHODS: An online survey was developed by the working Group on Geriatrics and Nutrition (GEGN) of the "Société Française de Gériatrie et de Gérontologie (SFGG)" and conducted among members of the SFGG. A self-administered questionnaire composed of 21 closed questions was used. RESULTS: A total of 132 (10.2 %) members of the SFGG responded to the survey. The respondents were aged 43.4 ± 9.94 years old and 97 (73.5 %) were women. Almost half of them were medical doctors (n = 53 ; 40.2 %). Of the respondents, 81 % had already heard of the HAS 2021 recommendations. This percentage is higher for doctors (96 %) than for other professions (74 %). French respondents were more likely to have heard of these -recommendations (84 %) than respondents from other countries (42.9 %). However, only 41.6 % of the respondents believe they know these recommendations in detail. On a visual analogue scale from 0 (never) to 100 (always), respondents use these recommendations in their professional practice at 76.8 ± 20.2 %. However, on a scale from 0 (never difficult) to 100 (always difficult), some barriers to their use in clinical practice were highlighted. These mainly concerned the measurement of muscle mass (84.4 ± 17.2 %) and muscle strength (79.5 ± 19.9 %) in patients. CONCLUSION: Although the majority of respondents use the HAS 2021 recommendations in their professional practice, they often have difficulties in measuring muscle strength and muscle mass of their patients. The assessment of sarcopenia still needs to be implemented in clinical routine. Until then, better communication about simple alternatives that do not require special equipment is needed.

Cross-sectional but not longitudinal association between n-3 fatty acid intake and depressive symptoms: results from the SU.VI.MAX 2 study.

Findings regarding the association between n-3 polyunsaturated fatty acid (PUFA) status and depression are conflicting. Thus, the authors studied associations between PUFA intake and depressive symptoms. In 1996, depressive symptoms were assessed in a subsample of participants from the Supplementation with Antioxidant Vitamins and Minerals (SU.VI.MAX) Study using the Center for Epidemiologic Studies Depression Scale (CES-D). In 2007-2009, information on CES-D score, history of depression, and use of antidepressant medication was obtained. Intakes of n-3 PUFAs were estimated from repeated 24-hour dietary records collected during 1994-1996. Subjects with depressive symptoms (cases) were identified using CES-D scores greater than 15 and/or antidepressant use. Logistic regression analyses were used. Cross-sectional (n = 2,744) and longitudinal (n = 1,235) associations between quartiles of PUFA intake and depressive symptoms were estimated. In cross-sectional analyses, quartile of n-3 PUFA intake was associated with lower odds of depressive symptoms (fourth quartile vs. first: odds ratio = 0.74, 95% confidence interval: 0.58, 0.95; P for trend = 0.001). No association between PUFA intake and incidence of depressive symptoms over 13 years was detected. This study provides new insights into the PUFA-depression link. While no association between n-3 PUFA intake and incidence of depressive symptoms was detected, an association was observed in cross-sectional analyses, which may reflect unhealthy dietary patterns among subjects with depressive symptoms.

A healthy dietary pattern at midlife is associated with subsequent cognitive performance.

Few studies have investigated the long-term impact of overall dietary patterns (DP) on cognition. We evaluated the association between empirically derived DP in midlife and cognitive performance 13 y later. Dietary data were based on 24-h dietary records obtained from a subsample of the Supplémentation en Vitamines et Minéraux Antioxydant Study. Cognitive performance was assessed via a battery of neuropsychological tests that included verbal fluency, the RI-48 cued recall test, the trail-making test, and forward and backward digit span. Three composite variables, for global cognitive function, verbal memory, and executive functioning, were built. The multivariate analyses were adjusted for baseline characteristics (age, gender, intervention group, education, alcohol and energy intake, number of dietary records, physical activity, BMI, tobacco use, self-reported memory troubles, diabetes, hypertension, and, for women, menopausal status and hormone therapy use), follow-up time, history of cardiovascular disease, and depressive symptoms. Adjusted means ± SEM of composite variables across quartiles (Q4 vs. Q1) of DP were estimated using ANCOVA. A healthy and a traditional DP were identified. In the multivariate model, the healthy pattern was associated with better global cognitive function (50.1 ± 0.7 vs. 48.9 ± 0.7; P-trend = 0.001) and verbal memory (49.7 ± 0.4 vs. 48.7 ± 0.4; P-trend = 0.01). These relationships were stronger in participants scoring below the gender-specific median values for energy intake (<2490 kcal for men and <1810 for women) than in those scoring at or above those values. Adherence to a healthy DP in middle life may help preserve global cognitive function, especially verbal memory, when total energy intake is regulated.

Serotonin syndrome during treatment with low dose of escitalopram associated with miconazole mucoadhesive tablet: a suspected drug interaction.

Antidepressant treatments, including selective serotonin reuptake inhibitors, are associated in older adults with an increased risk of adverse effects compared to younger adults. This is partly explained by multiple drug use causing drug-drug interactions. In the present report, we describe a case of serotonin syndrome in an 88-year-old woman receiving a low dose of escitalopram. The onset of this episode could have been induced by a drug-drug interaction with an acute treatment by miconazole gingival adhesive tablets. The lack of pharmacokinetic data in the elderly population should prompt us to be especially cautious about prescription of this new formulation of miconazole in association with drugs metabolized by cytochromes P450 isoenzymes.

The influence of Alzheimer's disease stigma on pain assessment in older persons.

INTRODUCTION: Pain of nursing homes residents with Alzheimer's disease remains under detected compared to their cognitively intact counterparts. Communication difficulties may partly explain this poor quality of care but the influence of stigmatization on pain assessment has never been explored. RESEARCH QUESTION: The objective of this research was to analyze whether a diagnosis label of Alzheimer's disease or the stage of the disease may bias pain assessment scores and empathic reactions of health care staff in nursing homes. METHODS: Two studies were conducted based on a similar experimental between-subjects design with a video showing an older adult woman experiencing undefined pain. Different labels and vignettes were manipulated to characterize the subject of the video. In the first study, 84 certified nursing assistants were asked to watch the video and then to assess the pain intensity and their empathic reaction. Participants were randomized in two conditions that varied the disease label (Alzheimer's disease vs no diagnosis). In the second study, 67 certified nursing assistants were enrolled who did not participate in the first study. They watched the same video as in the first study and assessed the pain intensity and their empathic reaction. They were randomized in two conditions that varied the stage of the Alzheimer's disease (mild stage vs severe stage). RESULTS: Alzheimer's disease label had no influence on assessment scores. In contrast, the stage of the disease had a significant effect on the health care staff assessments with severe stage associated with lower pain intensity scores and empathic reactions. CONCLUSION: These results confirm that the Alzheimer's disease stigma is a real phenomenon that tends to be mainly elicited by the symptoms of the acute phase of the disease. These findings are crucial to better understand the stigma related to Alzheimer's disease and to enhance the pain management of this frail population.

Quality of life and sarcopenic patients.

Sarcopenia is defined as a progressive and generalised loss of muscle strength, muscle mass and physical performance with advancing age. Among the multiple consequences of sarcopenia, the reduction in the quality of life associated with it can undeniably be considered as a major consequence. Quality of life is measured via generic or specific questionnaires. Current research, mainly using so-called "generic" questionnaires, has identified a reduced quality of life in patients with primary age-related sarcopenia, mainly in areas related to functional status and physical performance. A specific quality of life questionnaire could, in combination with a generic questionnaire, provide more precise data on the impact that sarcopenia has on patient's quality of life. The first quality of life questionnaire specific to sarcopenia, the SarQoL®, was developed in 2015. Psychometric validation of the SarQoL® has been carried out in several international patient populations indicating excellent internal consistency, reliability and convergent validity and sensitivity to change, as well as an absence of floor and ceiling effects. In combination with a generic questionnaire, this specific questionnaire is therefore suitable for measuring the quality of life of populations suffering from sarcopenia, both in research and in clinical practice and in the context of both observational or interventional evaluations.

Spreading geriatric oncology culture through professional caregivers: Results of a French massive open online course (MOOC).

Geriatric oncology is based on the synergy between several professionals whose common goal is to improve care for older patients with cancer. This requires sharing a common core of knowledge to facilitate collaboration between them. To date, training in geriatric oncology has been limited in scope and difficult to access for caregivers, particularly nurses and healthcare aides. To meet this need, a massive open online course (MOOC), in geriatric oncology has been developed in France. This kind of course aims to provide simultaneous access for a large number of participants and to foster communication with the pedagogical team through discussion forums. The first session of the MOOC, which has been set up in the Occitania region of France, went online nationwide from March 6 to June 23, 2020. Despite the SARS CoV-2 global health crisis, 1020 people subscribed to the first session and 417 (40.9%) were certified at the end of the course. Most are nurses (35.2%) and work outside Occitania (56.3%). A survey revealed a high satisfaction level regarding relevance of lessons (97.9%), pedagogical quality of teaching team (97.9%), knowledge acquisition (93.6%), meeting learners' needs (90.4%) and practical value of the course (88.3%). This preliminary experience demonstrates the ability of this MOOC to spread the culture of geriatric oncology and the educational potential of this new type of online training.
