Impact of the first COVID-19 epidemic wave in a large French network of nursing homes: a cross-sectional study.

BACKGROUND: Nursing homes (NHs) have been particularly affected by COVID-19. The aim of this study is to estimate the burden of COVID-19 and to investigate factors associated with mortality during the first epidemic wave in a large French NHs network. METHODS: An observational cross-sectional study was conducted in September-October 2020. 290 NHs were asked to complete an online questionnaire covering the first epidemic wave on facilities and resident characteristics, number of suspected/confirmed COVID-19 deaths, and preventive/control measures taken at the facility level. Data were crosschecked using routinely collected administrative data on the facilities. The statistical unit of the study was the NH. Overall COVID-19 mortality rate was estimated. Factors associated with COVID-19 mortality were investigated using a multivariable multinomial logistic regression. The outcome was classified in 3 categories: "no COVID-19 death in a given NH", occurrence of an "episode of concern" (at least 10% of the residents died from COVID-19), occurrence of a "moderate episode" (deaths of COVID-19, less than 10% of the residents). RESULTS: Of the 192 (66%) participating NHs, 28 (15%) were classified as having an "episode of concern". In the multinomial logistic regression, moderate epidemic magnitude in the NHs county (adjusted OR = 9.3; 95%CI=[2.6-33.3]), high number of healthcare and housekeeping staff (aOR = 3.7 [1.2-11.4]) and presence of an Alzheimer's unit (aOR = 0.2 [0.07-0.7]) were significantly associated with an "episode of concern". CONCLUSIONS: We found a significant association between the occurrence of an "episode of concern" in a NH and some of its organizational characteristics and the epidemic magnitude in the area. These results can be used to improve the epidemic preparedness of NHs, particularly regarding the organization of NHs in small units with dedicated staff. Factors associated with COVID-19 mortality and preventive measures taken in nursing homes in France during the first epidemic wave.

Executive dysfunction and effectiveness of physical program in older adults: which association?

BACKGROUND: Little is known about the association between executive function and the magnitude of improvement from personalised exercise interventions on gait performance among older-old adults. AIM: We examined whether the effectiveness of personalised intervention on gait performance is dependent on the patient's baseline dysexecutive syndrome, as assessed by the Frontal Assessment Battery. METHODS: A total of 175 older community-dwellers (83.57 ± 5.2 years; 70.2% female) were recruited from the day centre for after-care and rehabilitation in the Nantes Ambulatory Centre of the Clinical Gerontology (France), and were followed during a pre-post-intervention, single-arm retrospective design. The intervention consisted of an individual personalised rehabilitation program over a period of 7 weeks, with twice-weekly sessions (45 min each). Gait speed in four conditions (preferred, fast, and under two dual-task conditions), Timed Up and Go test, and handgrip strength test were assessed. RESULTS: Using a pre-post analysis of covariance, a significant increase in dual-task gait speed while counting (+ 0.10 m/s; + 15%) and in dual-fluency gait speed (+ 0.06 m/s; + 10%), and in Timed Up and Go performance (- 2.9 s; + 17.8%) was observed after the rehabilitation program, regardless the baseline executive status. DISCUSSION: An individual personalized intervention is effective to improve mobility performance and the dual-task gait speed in older-old adults. The magnitude of those effects is independent of the patient's baseline characteristics including the executive function status. CONCLUSIONS: Even the most deficient baseline characteristics of patients should not be viewed as clinical barrier for implementing a beneficial individual intervention in high-risk older adults.

Plasma amyloid beta predicts conversion to dementia in subjects with mild cognitive impairment: The BALTAZAR study.

INTRODUCTION: Blood-based biomarkers are the next challenge for Alzheimer's disease (AD) diagnosis and prognosis. METHODS: Mild cognitive impairment (MCI) participants (N = 485) of the BALTAZAR study, a large-scale longitudinal multicenter cohort, were followed-up for 3 years. A total of 165 of them converted to dementia (95% AD). Associations of conversion and plasma amyloid beta (Aß)1-42 , Aß1-40 , Aß1-42 /Aß1-40 ratio were analyzed with logistic and Cox models. RESULTS: Converters to dementia had lower level of plasma Aß1-42 (37.1 pg/mL [12.5] vs. 39.2 [11.1] , P value = .03) and lower Aß1-42 /Aß1-40 ratio than non-converters (0.148 [0.125] vs. 0.154 [0.076], P value = .02). MCI participants in the highest quartile of Aß1-42 /Aß1-40 ratio (>0.169) had a significant lower risk of conversion (hazard ratio adjusted for age, sex, education, apolipoprotein E ε4, hippocampus atrophy = 0.52 (95% confidence interval [0.31-0.86], P value = .01). DISCUSSION: In this large cohort of MCI subjects we identified a threshold for plasma Aß1-42 /Aß1-40 ratio that may detect patients with a low risk of conversion to dementia within 3 years.

National French Survey of Coronavirus Disease (COVID-19) Symptoms in People Aged 70 and Over.

The objective of this national French survey was to determine the coronavirus disease 2019 (COVID-19) semiology in seniors (n = 353; mean, 84.7 ±â€…7.0 years). A total of 57.8% of patients exhibited ≤3 symptoms, including thermal dysregulation (83.6%), cough (58.9%), asthenia (52.7%), polypnea (39.9%), and gastrointestinal signs (24.4%). Patients ≥80 years exhibited falls (P = .002) and asthenia (P = .002). Patients with neurocognitive disorders exhibited delirium (P < .001) and altered consciousness (P = .001). Clinical peculiarities of COVID-19 were reported in seniors. CLINICAL TRIALS REGISTRATION: NCT04343781.

Impact of an individual personalised rehabilitation program on mobility performance in older-old people.

BACKGROUND: Studies have shown benefits of exercise interventions on preferred and fast gait speed in healthy older adults, but the impact of a personalised rehabilitation program targeting a large cohort of non-disabled older-old adults has rarely been examined. AIMS: The purpose was to determine whether personalised intervention-related improvements in gait and mobility performance in older-old adults were dependent on cognitive status and/or history of falls. METHODS: Based on a pre-post design, 483 older-old persons (mean age: 83.3 ± 5.1 years) were followed during a personalised rehabilitation program over a period of 7 weeks, with twice-weekly sessions (45 min each). Gait speed in four conditions (preferred, fast, and under two dual-task conditions), static postural sway, Timed Up and Go test, Five Times Sit to Stand test, the ability to rise from the floor, and handgrip strength test were assessed. RESULTS: Using a pre-post analysis of covariance, a significant increase in preferred gait speed (+ 20.1%), fast gait speed (+ 15.8%), and dual-task speed while counting (+ 13.4%) was observed after the rehabilitation, regardless of the baseline cognitive status and fall history. Similar improvements in TUG and maximal handgrip force were observed, with a significant reduction of performance time (-19.5%) or an increase of handgrip strength (+ 6.2%). DISCUSSION: Results suggest the effectiveness of personalised intervention to improve a battery of physical performance measures in older-old adults, even for the frailest participants. CONCLUSION: Implementing a personalised intervention for targeting the high-risk older-old adults in priority is critical regarding the clinically meaningful change in gait speed.

Antibiotics prescription and guidelines adherence in elderly: impact of the comorbidities.

BACKGROUND: Although the interest of antibiotics is well known, antibiotics prescription is associated with side effect, especially in patients with multiples comorbidities. One way to reduce the incidence of side effects is to respect antibiotics prescriptions guidelines. Our objective was to investigated the factors associated with guidelines adherence in elderly patients with multiples comorbidities. METHODS: From October 2015 to December 2016, antibiotics prescription and guidelines adherence were analyzed in two post-acute care and rehabilitation services of a 2600-bed, university-affiliated center. RESULTS: One hundred and twenty-eight patients were included, fifty-nine (46%) patients had antibiotics prescription according to guidelines. In Multivariable logistic regression analysis, prescription of 2 antibiotics or more (OR = 0.168, 95% IC = 0.037-0.758, p < 0.05), 85 years of age and more (OR = 0.375, 95% IC = 0.151-0.931, p < 0.05) and the Charlson comorbidity index score (OR = 0.750, 95% IC = 0.572-0.984, p < 0.05) were negatively associated with antibiotics prescriptions according to guidelines. CONCLUSIONS: High comorbidity in the elderly was negatively associated with the guidelines adherence of antibiotiсs prescriptions. These criteria should be considered to optimize antibiotics prescriptions in elderly patients.

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.

Plasma amyloid levels within the Alzheimer's process and correlations with central biomarkers.

INTRODUCTION: Diagnostic relevance of plasma amyloid ß (Aß) for Alzheimer's disease (AD) process yields conflicting results. The objective of the study was to assess plasma levels of Aß42 and Aß40 in amnestic mild cognitive impairment (MCI), nonamnestic MCI, and AD patients and to investigate relationships between peripheral and central biomarkers. METHODS: One thousand forty participants (417 amnestic MCI, 122 nonamnestic MCI, and 501 AD) from the Biomarker of AmyLoïd pepTide and AlZheimer's diseAse Risk multicenter prospective study with cognition, plasma, cerebrospinal fluid (CSF), and magnetic resonance imaging assessments were included. RESULTS: Plasma Aß1-42 and Aß1-40 were lower in AD (36.9 [11.7] and 263 [80] pg/mL) than in amnestic MCI (38.2 [11.9] and 269 [68] pg/mL) than in nonamnestic MCI (39.7 [10.5] and 272 [52] pg/mL), respectively (P = .01 for overall difference between groups for Aß1-42 and P = .04 for Aß1-40). Globally, plasma Aß1-42 correlated with age, Mini-Mental State Examination, and APOE Îµ4 allele. Plasma Aß1-42 correlated with all CSF biomarkers in MCI but only with CSF Aß42 in AD. DISCUSSION: Plasma Aß was associated with cognitive status and CSF biomarkers, suggesting the interest of plasma amyloid biomarkers for diagnosis purpose.

NEURODEM: assessment of the iatrogenic alert indicator for nursing home patients with Alzheimer's or Alzheimer-like disease.

INTRODUCTION: Neuroleptics are known to induce Parkinsonism, tardive dyskinesia and their long-term use was associated with increased risk of hip fractures and impaired cognitive function and even death. METHODS: The primary objective of Neurodem study was to determine the IAI of patients with Alzheimer's disease in French NH. RESULTS: 1022 patients were enrolled. The IAI was 24.8 %. Multivariate logistic analysis showed that having a severe form of dementia, resident without MMS evaluation the last 12 months and having a prescription for an anxiolytic drug were associated with a higher risk of having a prescription for an antipsychotic drug. CONCLUSION: The results from our study show that the percentage of patients receiving an antipsychotic drug (24.8 %) was higher than the national average (18 %). Effective educational activities about appropriate use of antipsychotic drugs in patients with Alzheimer's disease are needed.

Burden of herpes zoster: the direct and comorbidity costs of herpes zoster events in hospitalized patients over 50 years in France.

BACKGROUND: The objectives of this study were to describe hospital stays related to HZ and to evaluate the direct and indirect cost of hospitalizations due to HZ among patients aged over 50 years. METHODS: The hospitalizations of people aged over 50 years were selected from the French national hospital 2011 database (PMSI) using ICD-10 diagnosis codes for HZ. Firstly, stays with HZ as principal or related diagnostic were described through the patient characteristics, type of hospitalization and the related costs. Secondly, a retrospective case-control analysis was performed on stays with HZ as comorbidity in 5 main hospitalizations causes (circulatory, respiratory, osteo-articular, digestive systems and diabetes) to assess the impact of HZ as co-morbidity on the length of stay, mortality rate and costs. RESULTS: In the first analysis, 2,571 hospital stays were collected (60 % of women, mean age: 76.3 years and mean LOS: 9.5 days). The total health assurance costs were 10,8 M€. Mean cost per hospital stay was 4,206€. In the second analysis, a significant difference in LOS and costs was shown when HZ was associated as comorbidity in other hospitalization's causes. CONCLUSIONS: HZ directly impacts on the hospital cost. When present as comorbidity for other medical reasons, HZ significantly increases the length of hospital stay with subsequent economic burden for the French Health System.

Healthcare costs associated with elderly chronic pain patients in primary care.

OBJECTIVE: This study aimed to estimate the total healthcare costs associated with elderly chronic pain (CP) patients, define cost-related factors in this population, and examine cost evolution over two years. METHOD: This is an ancillary study from the CP S.AGE subcohort, including non-institutionalized patients aged over 65 suffering from CP. 1190, 1108, 1042, and 950 patients were reviewed with available healthcare data at follow-up visits at 6, 12, 18, and 24 months, respectively. Healthcare components included medical and paramedical visits, medication prescription, and hospitalization. RESULT: The mean total cost in the first semester was estimated at 2548 ± 8885 per patient. Hospitalization represented the largest cost component (50%) followed by paramedical care (24%), medications (21%), and medical visits (5%). Significant cost-associated factors were comorbidity (OR 1.49, 95% CI 1.35-1.64), dependency in daily activities (OR 1.85, 95% CI 1.39-2.47), probable depression (OR 1.71, 95% CI 1.09-2.69), permanent pain (OR 1.48, 95% CI 1.18-1.86), neuropathic pain (OR 1.94, 95% CI 1.38-2.73), living alone (OR 1.45, 95% CI 1.16-1.82), chronic back pain (OR 1.35, 95% CI 1.07-1.71), and vertebral fracture/compression (OR 1.47, 95% CI 1.08-2.01). Healthcare costs increased significantly by 48% (p < 0.0001) during follow-up namely due to hospitalizations. Elevated costs were associated with a higher risk of future hospitalization (OR 1.95, CI 95% 1.33-2.87). CONCLUSION: Healthcare costs increased rapidly over time, largely due to hospitalization. Prevention strategies to limit hospitalizations in elderly appear to be the most useful in order to achieve cost savings in the future.

There is no correlation between peripheral inflammation and cognitive status at diagnosis in Alzheimer's disease.

BACKGROUND: Besides the neurofibrillary tangles and amyloid plaques, an inflammatory process is involved at central and peripheral levels in Alzheimer's disease (AD). We aimed to determine whether peripheral inflammatory parameter levels, in plasma and in peripheral blood mononuclear cells (PBMCs), could be correlated with the cognitive status at the time of AD diagnosis. METHODS: Patients were included at diagnosis with MMSE score between 16 and 25 and were naive of symptomatic treatment for AD. C-reactive protein >10 mg/L and any acute or chronic inflammation were considered as exclusion criteria. Cognitive assessment also included the ADAScog scale. Plasma interleukins (IL)-1ß, IL-6, tumor necrosis factor (TNF)-α and the chemokine ligand 5 (CCL5) were measured using Luminex(®) X-MAP(®) technology. A subgroup of patients also underwent measures of these parameters in extracellular and intracellular compartments of PBMCs (ancillary study). RESULTS: One hundred and nine patients were included; mean age 79.4 ± 6.8 years with 37 patients in the ancillary study. The mean values of IL-1ß, TNF-α, IL-6 and CCL5 values were 1.49, 7.18, 3.09 and 69,615.81 pg/mL, respectively. No correlation between plasma cytokines or chemokine levels and cognitive scores was found. In PBMCs, the levels of cytokines were detectable but did not either show any correlation with cognitive scores. CONCLUSION: Our data indicate that at diagnosis, peripheral levels of cytokines and CCL5 display low values without any correlation with the cognitive status. Further results of our study will show if these circulating markers are related to the progression of AD.

Predicting falls in elderly patients with chronic pain and other chronic conditions.

BACKGROUND: The aim was to identify fall predictors in elderly suffering from chronic pain (CP) and to test their applicability among patients with other chronic conditions. METHODS: 1,379 non-institutionalized patients aged 65 years and older who were suffering from CP (S.AGE CP sub-cohort) were monitored every 6 months for 1 year. Socio-demographic, clinical and pain data and medication use were assessed at baseline for the association with falls in the following year. Falls were assessed retrospectively at each study visit. Logistic regression analyses were performed to identify fall predictors. The derived model was applied to two additional S.AGE sub-cohorts: atrial fibrillation (AF) (n = 1,072) and type-2 diabetes mellitus (T2DM) (n = 983). RESULTS: Four factors predicted falls in the CP sub-cohort: fall history (OR: 4.03, 95 % CI 2.79-5.82), dependency in daily activities (OR: 1.81, 95 % CI 1.27-2.59), age ≥75 (OR: 1.53, 95 % CI 1.04-2.25) and living alone (OR: 1.73, 95 % CI 1.24-2.41) (Area Under the Curve: AUC = 0.71, 95 % CI 0.67-0.75). These factors were relevant in AF (AUC = 0.71, 95 % CI 0.66-0.75) and T2DM (AUC = 0.67, 95 % CI 0.59-0.73) sub-cohorts. Fall predicted probability in CP, AF and T2DM sub-cohorts increased from 7, 7 and 6 % in patients with no risk factors to 59, 66 and 45 % respectively, in those with the four predictors. Fall history was the strongest predictor in the three sub-cohorts. CONCLUSION: Fall history, dependency in daily activities, age ≥75 and living alone are independent fall predictors in CP, AF and T2DM patients.

Consequences of dextropropoxyphene market withdrawal in elderly patients with chronic pain.

OBJECTIVE: Describe the consequences of dextropropoxyphene (DXP) market withdrawal on analgesic prescriptions and on the quality of therapeutic management of chronic pain. PATIENTS AND METHODS: From a cohort of non-institutionalised elderly patients with chronic pain recruited by general practitioners, we selected patients who were treated with DXP daily for at least 6 months just prior to DXP market withdrawal and who had an evaluation of pain and its impact on daily activities before and after DXP withdrawal. RESULTS: One hundred three patients took DXP daily for chronic pain. Immediately after DXP market withdrawal, 42 (40.8%), 55 (53.4%) and 3 (2.9%) patients were treated with step 1, 2 and 3 analgesics, respectively, and 3 patients (2.9%) were no longer receiving any analgesic medication. Among the 55 patients who continued on step 2 analgesics, 37 were treated with tramadol, 14 with codeine and 9 with opium. Pain intensity and the impact of pain on daily activities remained stable. CONCLUSION: DXP market withdrawal had no consequences on the intensity or impact of chronic pain in elderly patients.

[An attempt to deconstruct the French "syndrome de glissement"]. / Essai de déconstruction du syndrome de glissement.

The "syndrome de glissement" is a French term used to describe end-of-life situations where the elderly person becomes adynamic and any therapeutic intervention seems ineffective until the patient dies. It is close to failure to thrive. Although its use, which is widespread, seems appropriate to briefly describe a complex situation, it has the major disadvantage of leading to an absence of clinical and therapeutic approach, which represents a loss of chance for the patient. In clinical practice, we consider that what is referred to as a sliding syndrome is actually a situation of apathy associated with a deterioration in general condition. A diagnostic approach should therefore look for all organic pathologies that associate deterioration in general condition and apathy, and neuropsychiatric situations such as episodes of major depression that produce such symptoms. Once these diagnoses have been ruled out, the person should be considered for palliative care and benefit from the expertise that goes with this practice. Any elderly person in a situation resembling what is known as a syndrome de glissement should therefore benefit from a rigorous clinical approach, and not be considered beyond any therapeutic resources. It is a matter of dignity and quality of care.

[Sociological and geographical markers in favour of a distance and potential availability score for the children of the very elderly]. / Jalons sociologiques et géographiques en faveur d'un score de distance et de disponibilité potentielle des enfants de personnes très âgées.

Old age is a time of emotional, social and physiological challenges. The role of the family remains essential in coping with these challenges. This is particularly true of non-cohabiting children, who in 2020 accounted for just under half of all those helping elderly people with loss of autonomy and/or pathologies. Following on from sociological research on close caregivers, this article first looks at the level and influence of children's relationships and assistance towards their elderly parents, and then proposes the construction of a territorial indicator - in this case, a score - to measure the spatial proximity and potential availability of children. Subject to further development, this indicator represents a first milestone in the territorial understanding of children's relationships with and help for their elderly parents.

[Prevalence and factors related to frailty dwelling home elderly -subjects using a modified SEGA scale: a study in primary care]. / Prévalence et facteurs associés à la fragilité chez des sujets âgés vivant à domicile à l'aide de la grille SEGA modifiée : une étude en soins primaires.

The prevalence of frailty determines the proportion of the population that will experience intercurrent events and dependency. The aim was to assess the prevalence and factors associated with frailty using the modified SEGA grid. METHOD: This was a cross-sectional descriptive study. The primary endpoint was frailty, assessed using the modified SEGA grid. RESULTS: The prevalence of frail and very frail people was jointly estimated at 33%. In multivariate analysis, gender, lifestyle and marital status did not appear to be associated with frailty. However, the IAVL score was associated with frailty OR=0.21 (95% CI 0.06 to 0.68; p=0.009). EVS is also associated with frailty for mild pain OR= 12.12 (95% CI 2.49 to 59.08; p=0.007). CONCLUSION: Our results independently show the association between IAVL and frailty, with a one-unit increase in IAVL score being less associated with frailty.

[Clostridioides difficile infections: Update and therapeutic guidelines]. / Infections à Clostridioides difficile : mise au point et repères thérapeutiques.

Clostridioides difficile infection (CDI) represents a significant challenge due to its increasing incidence, severity, and treatment difficulty. Effective management requires a multifactorial approach that includes preventive strategies, prudent antibiotic use, and adapted therapeutic options. Ongoing research and innovation offer promising prospects for improving ICD management, making vigilance and informed practices essential among healthcare professionals. Two main complications of ICD are pseudomembranous colitis (PMC) and toxic megacolon. PMC involves severe colonic inflammation due to C. difficile toxins, leading to pseudomembrane formation. Diagnosis relies on clinical criteria, microbiological tests, and endoscopy. Toxic Megacolon is characterized by severe colonic dilation and systemic toxicity, requiring immediate medical intervention. ICD diagnosis combines clinical signs and microbiological tests. These tests include toxin tests, GDH antigen detection, PCR for toxin genes, and stool culture. Imaging techniques assess colonic inflammation and complications. Combined diagnostic criteria from the American Gastroenterological Association (AGA) and European guidelines emphasize integrating clinical and laboratory findings for accurate diagnosis. ICD treatment involves stopping the implicated antibiotics and starting specific antimicrobial therapy. Common treatments include mainly fidaxomicin and oral vancomycin. Fecal microbiota transplantation (TMF) is recommended for recurrent cases unresponsive to standard treatments. Bezlotoxumab, an antibody targeting C. difficile toxin B, is used to prevent recurrence in high-risk adults. ICD poses a major challenge due to its increasing incidence, severity, and difficulty in treatment. A multifactorial approach involving rigorous preventive strategies, prudent antibiotic management, and adapted therapeutic options is essential for controlling the infection. Ongoing research and innovations in treatment offer promising prospects for improving patient management. Healthcare professionals must remain vigilant and informed to ensure effective practices in combating this infection and utilizing available resources optimally.

Reliability of a 2D-Panoramic Ultrasound System for the Determination of Muscle Volume in Older Hospitalized Patients.

ABSTRACT: Reliability of muscle thickness assessed in B-mode ultrasound has been confirmed in adults but remains a less direct assessment of muscle mass than muscle volume (MV). The aim of this prospective monocentric study was to assess the interday reliability of MV determined by the 2D-panoramic ultrasound in older hospitalized patients.Ten participants hospitalized in geriatric ward (mean age = 84) underwent 2 sessions of panoramic ultrasound scanning 1 week apart for MV assessment and DXA for leg lean mass (LLM) assessment when it was possible. The interday reliability of MV assessed using the intraclass correlation coefficient (ICC) was excellent, whatever was the muscle analyzed: ICC = 0.99 for tibialis anterior; ICC = 0.99 for vastus lateralis; ICC = 1 for rectus femoris. The pilot analysis of its association with leg lean mass revealed a good association between the vastus lateralis MV and LLM, but this needs to be confirmed on a larger number of participants (Pearson correlation coefficient = 0.91, P = 0.03).The 2D-panoramic ultrasound system for the determination of MV was reliable in older hospitalized patients with measurements performed on the patient's bed. MV seemed to be more correlated to LLM than muscle thickness. Future research will need to reduce the data processing time maybe with automation of data measurement.

Fragility and quality of life, the benefits of physical activity for the elderly / Fragilité et qualité de vie, les apports de l'activité physique chez la personne âgée

Frailty and quality of life are concepts that emerged in the second half of the 20th century. Frailty can be defined as a clinical syndrome of decreased physiological reserves and resistance against stressful events conferring high risk for adverse health outcomes, including loss of independence, falls, hospitalization, institutionalization and mortality. However, it is considered that frailty can potentially be prevented or treated with specific modalities. Quality of life has various definitions because of its subjective nature. The World Health Organisation defined quality of life as "an individual's perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns". The aim of this study is to review information regarding the potential association between frailty and quality of life in the elderly, and the effects of physical activity among different parameters of these phenomena. There are few studies that investigate links between frailty, quality of life and physical activity. However, results tend to show that physical aspects of frailty syndrome are inversely proportional to the quality of life in several of its dimensions. Furthermore, community-based exercise programs involving the elderly seem to improve the quality of life. Considering that physical activity can potentially have an impact on the quality of life among frail elderly and promote healthy aging, further research will be necessary to corroborate these results.

La fragilité et la qualité de vie sont des concepts qui font leur apparition dans la deuxième moitié du XXe siècle. La fragilité se situe entre le vieillissement usuel et pathologique. Il reflète une diminution de la faculté de l'organisme à résister à un stress, favorisant la survenue d'évènements péjoratifs de santé. Il s'agit d'un syndrome clinique multifactoriel potentiellement réversible via des actions de prévention. La qualité de vie est un concept très large et multifactoriel correspondant à la perception qu'un individu a de sa place dans la vie. Ce travail a pour double objectif d'étudier l'existence d'un lien potentiel entre fragilité et qualité de vie, et d'évaluer les bénéfices de la pratique d'une activité physique sur ces phénomènes. Les recherches dans ce domaine tendent à montrer que la présence d'une fragilité chez la personne âgée induit une altération des différents domaines de la qualité de vie, notamment en termes d'état de santé perçu. Les résultats d'études interventionnelles incluant des programmes d'activité physique indiquent un bénéfice à la fois sur les paramètres physiques de la fragilité, mais également sur la qualité de vie. Toutefois, le niveau de preuve reste faible et de futures recherches seront nécessaires.
