This study provides new information about the influence of the contraction pattern (i.e., continuous and intermittent) on the development of neuromuscular fatigability when exercise is performed until exhaustion. Maximal torque production is similarly reduced by both exercises, whereas maximal torque sustainability is impaired only after the continuous exercise. To evaluate neuromuscular fatigability, we then recommend using a sustained maximal voluntary contraction since this measure allows to concurrently collect information on complementary aspects of neuromuscular fatigability.

Level of medical intervention (LMI) has to be adapted to each patient in geriatric care. LMI scales intend to help nonintensive care (NIC) decisions, giving priority to patient choice and collegial discussion. In the present study, we aimed to assess the parameters associated with the NIC decision and whether these parameters differ from those associated with in-hospital mortality.Prospective observational study.All consecutive patients from a French 62-bed acute geriatric unit over 1 year.Factors from the geriatric assessment associated with the decision of NIC were compared with those associated with in-hospital and 1-year mortality, in univariate and multivariate analyses.In total, 1654 consecutive patients (median age 87 years) were included. Collegial reflection led to NIC decision for 532 patients (32%). In-hospital and 1-year mortality were 22% and 54% in the NIC group vs 2% and 27% in the rest of the cohort (P .001 for both). In multivariable analysis, high Charlson Comorbidity Index [odds ratio (OR) 1.15, 95% confidence interval (CI) 1.06-1.23, per point], severe neurocognitive disorders (OR 2.78, 95% CI 1.67-4.55), dependence (OR 1.92, 95% CI 1.45-2.59), and nursing home residence (OR 2.38, 95% CI 1.85-3.13) were highly associated with NIC decision but not with in-hospital mortality. Conversely, acute diseases had little impact on LMI despite their high short-term prognostic burden.Neurocognitive disorders and dependence were strongly associated with NIC decision, even though they were not significantly associated with in-hospital mortality. The decision-making process of LMI therefore seems to go beyond the notion of short-term survival.

A better knowledge of major neurocognitive disorders and motor learning allows us to propose motor rehabilitation (MR) adapted to subjects with Alzheimer's disease. Recent neuroscientific data on motor functions and cognition allow the construction of physical activity and MR programs, for which the dose-response relationship, content and instructions are determining factors. Further studies are needed to confirm the effectiveness of the methods used.

Because of heterogeneity of the elderly population and medical practices, the decision of admission of elderly patients (EP) in intensive care unit is more complex. This study aimed to determine the decision criteria for an early limitation of transfer in intensive care unit (ELTICU) of patients hospitalized in an acute geriatric unit. This retrospective study included, over a 10-month period, patients ≥75 years and hospitalized in an acute geriatric unit. They were divided into 2 groups according to whether or not an ELTICU decision was taken. In total, 906 EP were included among them 446 with no ELTICU decision. Univariate analysis showed a correlation between ELTICU and a Mini Mental Status score of less than 20/30. Malnutrition had no impact on ELTICU decision. In multivariate analysis, the factors associated with an ELTICU decision were an age ≥ 85 years, an hospitalization in the last 6 months (Odds Ratio (OR) = 1.72, Confidence Interval (CI) 95% [1.23-2.39]), life in a nursing home (OR = 1.93, 95% CI [1.18-3.16]) and the presence of bedsore(s) (OR = 2.44, 95% CI [1.20-4.98]). A null Charlson score was associated with the absence of an ELTICU decision (OR = 0.42, 95% CI [0.26-0.67]). Some criteria are shared between geriatricians, resuscitators and emergency physicians, while others are discordant, illustrating differences in physicians' practices.

For decades, the literature was skeptical about the feasibility of motor rehabilitation and its impact, as well as that of physical activity (PA), in subjects with major neurocognitive disorders (MNCD), including Alzheimer's disease. Now, authors report several benefits of PA, both physical and cognitive, by promoting brain perfusion, neurogenesis and synaptic plasticity, as well as decreasing oxidative stress and inflammation. PA should be recommended in cases of TNCM.

Simple Summary COVID-19 pneumonia can be confused with Pneumocystis jirovecii pneumonia (PJP) on computed tomography and is a source of misdiagnosis. This can lead to mistreatment and an increased risk of mortality. Gefitinib, a tyrosine kinase inhibitor anti-EGFR used in cancer therapy and corticosteroids, could increase the risk of PJP. Abstract An 82-year-old woman treated for advanced lung cancer with gefitinb was admitted to the emergency unit complaining of dyspnea. Chest computed tomography found abnormalities classified as possible diffuse COVID-19 pneumonia. RT-PCR for Sars-Cov-2 was twice negative. PCR for Pneumocystis jirovecii was positive on bronchoalveolar lavage. The final diagnosis was Pneumocystis jirovecii pneumonia. Therefore, physicians must be careful not to misdiagnose COVID-19, especially in cancer patients on small-molecule therapeutics like gefitinib and corticosteroids.

Apyrexia is increasingly recognized as an indicator of inadequate inflammatory response in older patients with suspected infection. We aimed to evaluate whether temperature at admission could improve the prognostic value of the Quick Sequential Organ Failure Assessment (qSOFA) for predicting in-hospital mortality after acute infection.We created a new score, named qSOFAGE (qSOFA in GEriatrics), by adding apyrexia as an item to the existing qSOFA (+ 1 point if temperature at admission ≤ 38 °C). We compared the prognostic value of the qSOFA, the qSOFAGE and temperature at admission for predicting in-hospital mortality after acute infection in two cohorts including older patients with acute pneumonia (AP) or bacteremic urinary tract infection (UTI).217 consecutive patients aged ≥ 75 hospitalized for AP (first cohort) and 105 for bacteremic UTI (second cohort) were recorded. Temperature at admission was strongly inversely correlated with in-hospital mortality in both cohorts (Odds Ratios per °C (95% Confidence Interval): 0.60 (0.45-0.80) and 0.46 (0.27-0.79) for AP and UTI. respectively). Adding the temperature ≤ 38 °C item to the qSOFA markedly improved its predictive value for in-hospital mortality in the two groups: C-statistics for qSOFAGE vs. qSOFA: 0.63 (0.53-0.73) vs. 0.56 (0.46-0.67) in AP cohort; 0.74 (0.58-0.89) vs. 0.69 (0.53-0.85) in UTI cohort. For patients with qSOFAGE ≥ 3, in-hospital mortality reached 37% after AP and 55% after bacteremic UTI.Temperature at admission was strongly correlated with mortality in these two cohorts of older patients hospitalized for acute infection. The next step will be to validate this score in cohorts of older patients with suspected infection.

This study aimed to identify markers of disease worsening in patients hospitalized for SARS-Cov2 infection.Patients hospitalized for severe recent-onset (1 week) SARS-Cov2 infection were prospectively included. The percentage of T-cell subsets and plasma IL-6 at admission (before any steroid therapy) were compared between patients who progressed to a critical infection and those who did not.Thirty-seven patients (18 men, 19 women) were included; 11 (30%) progressed to critical infection. At admission, the critical infection patients were older (P = 0.021), had higher creatinine levels (P = 0.003), and decreased percentages of circulating B cells (P = 0.04), T cells (P = 0.009), and CD4+ T cells (P = 0.004) than those with a favorable course. Among T cell subsets, there was no significant difference between the two groups except for the percentage of Th17 cells, which was two-fold higher in patients who progressed to critical infection (P = 0.028). Plasma IL-6 at admission was also higher in this group (P = 0.018). In multivariate analysis, the percentage of circulating Th17 cells at admission was the only variable associated with higher risk of progression to critical SARS-Cov2 infection (P = 0.021).This study suggests that an elevated percentage of Th17 cells in patients hospitalized for SARS-Cov2 infection is associated with an increased risk of progression to critical disease. If these data are confirmed in a larger study, this marker could be used to better target the population of patients in whom tocilizumab could decrease the risk of progression to critical COVID-19.

Type 2 myocardial infarction (MI) is characterised by a functional imbalance between myocardial oxygen supply and demand in the absence of a thrombotic process, leading to myocardial necrosis. This type of MI was relatively unknown among clinicians until the third universal definition of MI was published in 2017, differentiating Type 2 from Type 1 MI, which follows an acute atherothrombotic event. The pathogenesis, diagnostic and therapeutic aspects of Type 2 MI are described in the present review. Type 2 MI is a condition that is strongly linked to age because of vascular ageing concerning both epicardic vessels and microcirculation, age-related atherosclerosis and stress maladaptation. This condition predominantly affects multimorbid individuals with a history of cardiovascular disease. However, the conditions that lead to the functional imbalance between oxygen supply and demand are frequently extra-cardiac (e.g. pneumonia or anaemia). The great heterogeneity of the underlying etiological factors requires a comprehensive approach that is tailored to each case. In the absence of evidence for the benefit of invasive reperfusion strategies, the treatment of Type 2 MI remains to date essentially based on the restoration of the balance between oxygen supply and demand. For older co-morbid patients with Type 2 MI, geriatricians and cardiologists need to work together to optimise etiological investigations, treatment and prevention of predisposing conditions and precipitating factors.

Lymphoid neoplasms are a heterogeneous group of lymphoid neoplastic diseases with multiple presentations, and varying prognoses. They are especially frequent in older patients (OPs) and the atypism of this frail elderly population can make the diagnostic process even more difficult. Blood lymphocyte immunophenotyping (BLI) is essential in rapid noninvasive diagnosis orientation and guides complementary investigations. To our knowledge, BLI prescription has never been evaluated in OPs. We hypothesized that, when there is a suspicion of lymphoid neoplasm in the geriatric population, a BLI is performed in view of various clinical or biological abnormalities. This study aimed to: (1) describe the characteristics of hospitalized OPs having undergone BLI for suspected lymphoid neoplasm, (2) identify the causes leading to BLI prescription, and (3) identify the most profitable criteria for BLI prescription. This was a descriptive retrospective study on 151 OPs aged ≥75 years who underwent BLI over a 2-year period. Regarding BLI prescriptions, eight had lymphocytosis, constituting the “lymphocytosis group” (LG+), while the 143 others had BLI prescribed for reasons other than lymphocytosis (LG−), mainly general weakness and anemia. In the LG−, we compared OPs with positive and negative BLI results. The criteria found to be profitable for BLI prescription were lymphadenopathy, splenomegaly, lymphocytosis, and thrombocytopenia. BLI identified circulating lymphoid neoplasms (positive BLI) in 21/151 OPs, mainly marginal zone lymphoma and chronic lymphocytic leukemia. In polymorbid OPs, as per our study population, the diagnostic and therapeutic complexity explained in part the sole use of indirect and minimally invasive diagnostic techniques such as BLI.

(1) Anemia often predisposes older patients to type 2 myocardial infarction (T2MI). However, the management of this frequent association remains uncertain. We aimed to evaluate the impact of red blood cell transfusion during the acute phase of T2MI in older anemic inpatients. (2) Methods and results: We performed a retrospective study using a French regional database. One hundred and seventy-eight patients aged 65 years or older, presenting with a T2MI and anemia, were selected. Patients were split into two groups: one that received a red blood cell transfusion (≥1 red blood cell unit) and one that did not. A propensity score was built to adjust for potential confounders, and the association between transfusion and 30-day mortality was evaluated with an inverse propensity score weighted Cox model. Transfusion was not associated with 30-day all-cause mortality (propensity score weighted hazard ratio (HR) 1.59 (0.55–4.56), p = 0.38). However, 1-year all-cause mortality was significantly higher in the transfusion group (propensity score weighted HR 2.47 (1.22–4.97), p = 0.011). (3) Conclusion: Our findings in older adults with anemia suggest that blood transfusion in the acute phase of T2MI could not be associated with improved short-term prognosis. Prospective studies are urgently needed to assess the impact of transfusion on longer-term prognosis.

Summary Background Clostridioides difficile infection (CDI) is a frequent and severe complication of antibiotic treatment in elderly patients hospitalized for acute pneumonia (AP). Aim To assess the burden and risk factors of CDI and to determine which of the usual antibiotics regimens is at lower risk for post-AP CDI incidence. Methods Among patients aged >75 years hospitalized for AP in all departments of a university hospital between 2007 and 2017, all the 92 patients developing CDI were compared with 213 patients without CDI. Factors associated with (i) in-hospital and one-year mortality and (ii) CDI incidence were assessed using logistic regression models. Findings In patients with and without CDI after AP, mortality rates were respectively at 34% vs 20% in hospital and 63% vs 42% at one year. After adjustment for confounders, CDI was associated with a two-fold risk of in-hospital and one-year mortality after pneumonia (respectively, odds ratio (OR): 1.95; 95% confidence interval (CI): 1.06–3.58; and OR: 2.02; 95% CI: 1.43–7.31). High number of antibiotics (per antibiotic, OR: 1.89; 95% CI: 1.18–3.06) rather than antibiotics duration (per day, OR: 1.04; 95% CI: 0.96–1.11) was associated with a higher risk of CDI. Compared with other antibiotics, use of penicillin + β-lactamase inhibitors was associated with a lower risk of CDI (OR: 0.43; 95% CI: 0.19–0.99). Conclusion In elderly inpatients, CDI greatly increases the burden of AP in the short and long term. If confirmed, these results suggest the preferential use of penicillin + β-lactamase inhibitors for a lower incidence of CDI in elderly inpatients with AP.

Falls are a major public health problem as a result of the high frequency of these events and morbidity/mortality among elderly persons. A prevention policy is a potential means to reduce the incidence of falls. This study aimed to assess the impact of a balance workshop in a geriatric day-hospital (GDH) on the prevention of falls in older adults. This was a prospective, single centre study conducted in the GDH of a general hospital. Motor tests and a psychological assessment were performed at 2 months (M2), 6 months (M6) and 1 year (M12). Sixty-five patients were included, aged 82.0 ± 7.7 years. Fifty-eight were women (89.2%). The statistical analyses showed a significant improvement in all motor tests during the follow-up at the defined intervals. The Timed Up and Go test (s) significantly decreased between inclusion, 19.1 ± 8.2, and M2, 15.8 ± 6.6 (P = 0.01 inclusion vs M2), then was stable at M6, 16.4 ± 6.9 (P = 0.04 inclusion vs M6) and at M12, 16.3 ± 6.4 (P = 0.04 inclusion vs M12). There was also significant psychological improvement throughout follow-up. The score on the Falls Efficacy Scale International-I decreased from 11.6 ± 6.1 at inclusion to 8.2 ± 5.5 at M2 (P = 0.001 inclusion vs. M2), 9.2 ± 6.0 at M6 (P = 0.02 inclusion vs. M6), and 9.0 ± 6.1 at M12 (P = 0.02 inclusion vs. M12). This study highlights the value and the need for balancing workshops in primary care.

Background. Better knowledge on caregivers is required to address their needs with dedicated support. The results from the ICE study explored the health-related quality of life (HRQoL) in caregivers of elderly with chronic disabilities, after social intervention or not.Methods. Caregivers of patients (≥60 years) with cancer, neurodegenerative disease, stroke, or age-related macular degeneration were randomized 1:1 in the supportive intervention group (support from social workers and information booklet) or in the control group (information booklet only), and completed questionnaires (short form-36 questionnaire (SF-36), Hospital Anxiety Depression Scale (HADS), and Zarit Burden Interview (ZBI) quarterly (6-monthly for ZBI) during two years. Caregiver characteristics, and caregiver HRQoL assessment through SF-36, HADS, ZBI scores at baseline, at 12 months (M12) and 24 months (M24) on an individual and an aggregate level, were described using paired-t test comparisons, and minimal important difference. Longitudinal assessments of caregiver HRQoL over the two first years were reported.Results. From 2015 to 2019, 179 caregivers supported patients with cancer (n=92, 52%), Alzheimer (n=46, 26%), Parkinson (n=20, 11%) were randomized. No evidence differences in SF-36 PCS and MCS summary scores mean change over time, neither in HADS anxiety and burden ZBI scores were shown. However, HADS depression mean changes showed a clinically significant increase of 1.4 (4.0) at M12, and 1.7 (4.1) at M24 in control group. Conclusion. Appropriate support need to be proposed to improve the global caregiver HRQoL, and reduce depression at 1 and 2 years.Trial registration number: This study was registered retrospectively with ClinicalTrials.gov NCT02626377 on 9th December 2015.

Due to the diversity of the elderly population and medical practices, the decision to transfer elderly patients to an intensive care unit is complex. This study aimed to identify the criteria used to take an advance decision to limit transfer to an intensive care unit of patients hospitalised in an acute geriatric unit.This retrospective study included, over a ten-month period, patients75 years and hospitalised in an acute geriatric unit. They were divided into two groups according to whether or not an advanced decision to limit transfer to an intensive care unit had been taken.In total, 906 elderly patients were included in the study. Of them, 446 had no advance decision to limit transfer to an ICU. Univariate analysis showed a correlation between an advance decision to limit transfer to an ICU and a Mini Mental State Examination (MMSE) score of less than 20/30. Malnutrition had no impact on the advance decision. In multivariate analysis, the factors associated with an advance decision to limit transfer to an ICU were an age 85 years, a hospitalisation in the last six months (Odds Ratio (OR) = 1.72, Confidence Interval (CI) 95% [1.23-2.39]), residence in a nursing home (OR = 1.93, 95% CI [1.18-0.16]) and the presence of bedsores (OR = 2.44, 95% CI [1.20-0.98]). A zero Charlson score was associated with the absence of an advance decision to limit transfer to an ICU (OR = 0.42, 95% CI [0.26-0.67]).Some criteria are common to geriatricians, intensive care doctors and emergency physicians, while others are discordant, illustrating differences in physicians' practices.

Anemia is common in older individuals, but it is not known whether the prognostic impact of transfusion differs according to cardiac troponin concentration.During this 2-year retrospective study in an acute geriatric unit, 514 patients with hemoglobin10 g/dL and troponin sampling were included. Thirty-day and 1-year mortality were compared according to transfusion status and troponin and hemoglobin levels.Of the 514 anemic patients included (median age 88 years), 157 (31%) had elevated troponin concentrations. These patients were more likely to die at 30 days (49% vs 27%, P.001) and 1 year (65% vs 51%, P = .004) than patients with normal values. Among patients with elevated troponin concentrations, 30-day mortality tended to be lower in transfused than in not-transfused patients (hazard ratio 0.48; 95% confidence interval, 0.21-1.08; P = .07). This association was not found in patients without troponin elevation (hazard ratio 1.09; 95% CI, 0.61-1.93; P = .8). Transfusion was associated with 30-day survival in patients with hemoglobin ≤8 g/dL. It was also associated with excess 1-year mortality in patients with hemoglobin8 g/dL.This pilot study suggests that transfusion could be associated with better 30-day outcomes in older anemic patients with anemia-related myocardial injury. Thus, troponin levels could be involved in decision-making relative to transfusion in anemic older patients. Clinical trials are needed to establish the benefit of transfusion in patients with elevated troponins.

Motor lateralization refers to differences in the neural organization of cerebral hemispheres, resulting in different control specializations between the dominant and the non-dominant motor systems. Multiple studies proposed that the dominant hemisphere is specialized for open-loop optimization-like processes. Recently, comparing arm kinematics between upward and downward movements, we found that the dominant arm outperformed the non-dominant one regarding gravity-related motor optimization in healthy young participants. The literature about aging effects on motor control presents several neurophysiological and behavioral evidences for an age-related reduction of motor lateralization. Here, we compare the lateralization of a well-known gravity-related optimal motor control process between young and older adults. Forty-one healthy young (mean age = 24.3 ± 3 years) and forty-two healthy older adults (mean age = 72.0 ± 6 years) performed single degree-of-freedom vertical arm movements between two targets (upward and downward). Participants alternatively reached with their dominant and non-dominant arms. We recorded arm kinematics and electromyographic activities of the prime movers (Anterior and Posterior Deltoids) and we analyzed parameters thought to represent the hallmark of the gravity-related optimization process (i.e directional asymmetries and negative epochs on the phasic EMG activity). We found strong age x arm interaction effects on all parameters; i.e., relative durations to peak acceleration and peak velocity and the negativity of antigravity muscles’ phasic signals. Although all three parameters showed a lateralization effect where the dominant arm was superior to the non-dominant arm in young adults (as in Poirier et al. 2022), we found no such effect in older adults. With both arms, the results of older adults lied between those of the dominant and non-dominant arm of young adults. These results add to those of recent literature showing that feedforward motor control remains functional in older adults. More, the results obtained with the non-dominant arm may support a previously hypothesized increased reliance on predictive mechanisms in older adults.

Healthcare workers (HCWs) are exposed to a higher risk of coronavirus disease (COVID-19) contamination. This prospective multicenter study describes the characteristics of HCWs tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) while working in a geriatric environment. We also compared HCWs with a positive reverse transcription polymerase chain reaction (RTPCR) assay (RTPCR+ group) and those with a negative test result (RTPCR− group). Between 15/5/2020 and 15/9/2020, 258 HCWs, employed in the acute geriatric unit (AGU), geriatric rehabilitation unit (GRU) or nursing home of three hospitals in Burgundy (France) were invited to complete an online survey. Among the 171 respondents, 83 participants, with mean age 42 years and 87.9% female, were tested for SARS-CoV-2 infection. Among these 83 participants, COVID-19 was confirmed in 38 cases (RTPCR+ group) of which 36 were symptomatic, and the RTPCR assay was negative in 45 cases (RTPCR− group) of which 20 participants were symptomatic. A total of 22.9% (of 83) had comorbidities, 21.7% were active smokers, and 65.1% had received the flu vaccine. A total of 37.3% worked in AGU, 19.3% in GRU and 16.9% in nursing homes. The most common symptom described was headache (23.2%), followed by fatigue or cough (12.5% each), and fever or myalgia (10.7% each). There were more participants with normal body mass index (p = 0.03) in the RTPCR+ group. In contrast, there were more users of non-steroidal anti-inflammatory drugs (p = 0.01), active smokers (p = 0.03) and flu vaccinated (p = 0.01) in the RTPCR− group. No difference was found between the two groups for the type of work (p = 0.20 for physicians and p = 0.18 for nurses). However, acquiring COVID-19 was significantly associated with working in AGU (p &lt, 0.001) and nursing homes (p = 0.001). There were significantly more users of surgical masks (p = 0.035) in the RTPCR+ group and more filtering facepiece-2 mask users (p = 0.016) in the RTPCR− group. Our results reflect the first six months of the COVID-19 pandemic in France. Further studies are needed to evaluate and track the risks and consequences of COVID-19 in HCWs.

International audience; BACKGROUND: Difficulties with meal-related activities (preparing meals and food shopping) may influence food intake, and contribute to nutritional risk among elderly people. All known studies on this topic had a cross-sectional design, thereby no causal relationships could be derived. We aim to investigate if difficulties with meal-related activities can contribute to subsequent weight loss in community-dwelling older people. METHODS: We used data of older subjects from the MAPT Study (n = 1531, median age = 74 years, 64% women), who provided prospective data on weight every 6 months and cognitive, physical condition, and functional capacities every year during a 3-year period. Difficulties preparing meals and shopping were evaluated each year with the Alzheimer's Disease Cooperative Study-Activities of Daily Living Prevention Instrument (ADCS ADL-PI) Scale. The risk of losing weight (≥5% or ≥ 3 kg in the following year) was estimated using a time-dependent Cox regression model. RESULTS: During the 3-year follow-up, a total of 851 subjects experienced at least a 5% or 3 kg weight loss. Two hundred thirty-seven subjects declared having difficulties with meal preparation at least once, and 133 declared having difficulties shopping. Subjects reporting any meal-related difficulties were older (p \textless 0.001), had more depressive symptoms (p \textless 0.001), and a lower physical function (p \textless 0.001) compared to those without difficulties. They also had a lower cognitive score (preparing meals: p \textless 0.001; shopping: p = 0.005) and a lower body mass index (preparing meals: p = 0.005; shopping: p = 0.023) at the end of the study. Meal-related activities were not associated with weight loss in unadjusted analysis and after adjustment for sex, age, depression, physical and cognitive status. CONCLUSION: Difficulties preparing meals and shopping had no effect on weight loss in community-dwelling older people, despite their association with advanced age, functional decline, and depressive symptoms.

We aimed to compare the mortality and comfort associated with high-flow nasal cannula oxygenation (HFNCO) and high-concentration mask (HCM) in older SARS-CoV-2 infected patients who were hospitalized in non-intensive care units. In this retrospective cohort study, we included all consecutive patients aged 75 years and older who were hospitalized for acute respiratory failure (ARF) in either an acute geriatric unit or an acute pulmonary care unit, and tested positive for SARS-CoV-2. We compared the in-hospital prognosis between patients treated with HFNCO and patients treated with HCM. To account for confounders, we created a propensity score for HFNCO, and stabilizing inverse probability of treatment weighting (SIPTW) was applied. From March 2020 to January 2021, 67 patients (median age 87 years, 41 men) were hospitalized with SARS-CoV-2-related ARF, of whom 41 (61%) received HFNCO and 26 (39%) did not. Age and comorbidities did not significantly differ in the two groups, whereas clinical presentation was more severe in the HFNCO group (NEW2 score: 8 (5–11) vs. 7 (5–8), p = 0.02, and Sp02/Fi02: 88 (98–120) vs. 117 (114–148), p = 0.03). Seven (17%) vs. two (5%) patients survived at 30 days in the HFNCO and HCM group, respectively. Overall, after SIPTW, HFNCO was significantly associated with greater survival (adjusted hazard ratio (AHR) 0.57, 95% CI 0.33–0.99, p = 0.04). HFNCO use was associated with a lower need for morphine (AHR 0.39, 95% CI 0.21–0.71, p = 0.005), but not for midazolam (AHR 0.66, 95% CI 0.37–1.19, p = 0.17). In conclusion, HFNCO use in non-intensive care units may reduce mortality and discomfort in older inpatients with SARS-CoV-2-related ARF.

Background It is uncertain whether antibiotic therapy should be started in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia. We aimed to investigate the association between early antibiotic therapy and the risk of in-hospital mortality in older patients. Methods We performed a retrospective international cohort study (ANTIBIOVID) in 5 coronavirus disease 2019 geriatric units in France and Switzerland. Among 1357 consecutive patients aged 75 or older hospitalized and testing positive for SARS-CoV-2, 1072 had radiologically confirmed pneumonia, of which 914 patients were still alive and hospitalized at 48 hours. To adjust for confounders, a propensity score for treatment was created, and stabilized inverse probability of treatment weighting (SIPTW) was applied. To assess the association between early antibiotic therapy and in-hospital 30-day mortality, SIPTW-adjusted Kaplan–Meier and Cox proportional hazards regression analyses were performed. Results Of the 914 patients with SARS-CoV-2 pneumonia, median age of 86, 428 (46.8%) received antibiotics in the first 48 hours after diagnosis. Among these patients, 147 (34.3%) died in hospital within 1 month versus 118 patients (24.3%) with no early antibiotic treatment. After SIPTW, early antibiotic treatment was not significantly associated with mortality (adjusted hazard ratio, 1.23; 95% confidence interval, 0.92–1.63; p = .160). Microbiologically confirmed superinfections occurred rarely in both groups (bacterial pneumonia: 2.5% vs 1.5%, p = .220; blood stream infection: 8.2% vs 5.2%, p = .120; Clostridioides difficile colitis: 2.4% vs 1.0%, p = .222). Conclusions In a large multicenter cohort of older inpatients with SARS-CoV-2 pneumonia, early antibiotic treatment did not appear to be associated with an improved prognosis.

A cross-sectional observational study was conducted to describe the lifestyle of people ≥90 years, living in Evdilos or Raches, two municipalities of the Greek island of Ikaria, classified a longevity blue zone. The 71 participants were interviewed and underwent the Mediterranean Islands study food frequency questionnaire (MEDIS-FFQ) and the international physical activity questionnaire (IPAQ). The frequency of social contacts was daily for 77.9% of participants, weekly for 16.1%, and monthly for 5.9%. Most participants (90.0%) believed in God, and 81.4% took part in religious events. A total of 62.0% attended Panigiria festivals. Access to primary health care was considered difficult in the past for 66.2% of participants, while 22.1% felt that it remained difficult at the time of the survey. The level of adherence to the Mediterranean diet was 62.7% (61.6% in women and 64.0% in men). Physical activity levels were moderate or high for 71.8% of participants (59.5% of women and 85.3% of men). In conclusion, the participants had a very high level of family solidarity, social interaction and physical activity. The results concerning the Mediterranean diet are less convincing. It would be interesting to study the impact of these factors on the longevity of the oldest old aged people living in Ikaria.
