ABSTRACT
INTRODUCTION: Elderly patients are a growing population in stroke units, characterized by higher frailty, but underrepresented in clinical trials about acute care. We investigated efficacy of intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) in elderlies in current practice. METHODS: We assessed consecutive patients with acute ischemic stroke (AIS) hospitalized in the four stroke units of the French Northern Alps Emergency Network between 2015 and 2020. We compared baseline characteristics, early neurological evolution and outcome of patients aged 80-89 and≥90years old (yo). RESULTS: Among 8367 patients, 2744 (32.8%) were 80-89 yo and 541 (6.5%) were≥90 yo. IVT and/or MT were performed in 787 patients≥80 yo (632 patients aged 80-89, 155 patients aged>90). Early neurological improvement was more frequent in patients≥80 yo treated by IVT and/or MT compared to untreated patients (45.6% versus 38.4%, P=0.002). After adjustment, reperfusion treatments improved likelihood of good outcome at discharge (OR=2.0 [1.6-2.7]) and reduced in-hospital mortality (OR=0.5 [0.4-0.7]). Age and initial NIHSS score were independent factors of poor functional outcome at discharge and in-hospital mortality. The rate of successful recanalization was comparable between octogenarians and nonagenarians (87% versus 85.2%, P=0.8). Octogenarians had better functional outcome at discharge compared to nonagenarians [modified Rankin scale (mRS) 0-2: 36% versus 25.7%, P=0.02], whatever IVT or MT strategy. In-hospital mortality was lower for octogenarians compared to nonagenarians (19.5% versus 27.1%, P=0.04). DISCUSSION: IVT and MT improve early neurological recovery and functional outcome at discharge of both octogenarians and nonagenarians in current practice. Despite a poorer outcome for nonagenarians than octogenarians, these reperfusion treatments should not be withheld on the basis of age only.

Infections commonly occur terminally ill oldest patients in palliative care and questioned about antimicrobial use. The aim of this study was to describe practitioners' habits. METHOD: ancillary study on antibiotic modalities according to the setting of care from a national practices survey based on self administered questionnaire sent by e-mail in 2017. RESULTS: 220 practitioners/327 used antibiotic, 136 worked in hospital department (52 geriatricians), 20 nursing home and 64 general practitioners (GP). GP declared less palliative care patients (6/year). The antibiotic goal was symptomatic relief for 181 (82.3%) without statistically significant difference between groups. GP (25%) were the group that most collected patient opinion for antibiotic prescription. Nursing home (23%) and GP (18%) reported more urinary tract symptoms than others (11.7%) (P=0.003). Geriatricians (59.6%) declared significantly less urinary analysis than GP (90%) (P=0.0009). 212 doctor (96.4%) faced side effect (SI): more allergic reaction and less administration difficulties than the other groups. The stop decision was collegially took (156, 70,9%) significantly more in hospital (121, 89%) than in community (25, 39.1%) (P<0.001). Patient wishes were noted by 30 (46.96%) only GP. CONCLUSION: Even if practice and number of patients follow up differ from each place of care, doctors' intention in antibiotic use respect palliative care goal to relieve discomfort. It is hard to diagnose infection and complementary exam are scarce. A repeated individualized evaluation with patient, his surrounding and his medical referent participation, is mandatory to give a constant adapted level of care in every place of care.

CONTEXT: The use of explicit definitions of potentially inappropriate prescriptions of antibiotics (antibiotic PIPs) might constitute an innovative means to fight against antimicrobial resistance. Explicit definitions of PIPs can reduce the rate of inappropriate prescriptions, but explicit definitions of antibiotic PIPs in geriatric medicine are currently lacking. The objective of the study was to develop explicit definitions of antibiotic PIPs for hospitalized older patients. METHOD: We performed a qualitative study of focus groups involving geriatricians and infectious disease specialists. The study complied with the Consolidated Criteria for Reporting Qualitative Research. Transcripts of audio recordings were analyzed in a two-step independent reviewing process. The exact wording of the definitions was validated by a steering committee, an independent expert group, and the focus group participants. RESULTS: The four focus groups comprised 28 stakeholders. Our analysis identified 65 explicit definitions of antibiotic PIPs: 47 (73%) concerned misuse, 15 (23%) concerned overuse and three (5%) concerned underuse. Most definitions were related to critically important antibiotics: 11 (17%) for fluoroquinolones, eight (12%) for amoxicillin-clavulanic acid, eight (12%) for cephalosporins, seven (11%) for aminoglycosides, and five (8%) for carbapenems. CONCLUSION: To address the public health challenge of antimicrobial resistance, our study generated explicit definitions for antibiotic PIPs in older patients. We intend to refine and to validate these definitions through a national Delphi survey; the resulting consensus might provide key messages for prescribers and open up perspectives for reducing the incidence of antibiotic PIPs.

Osteoarthritis (OA) is a chronic degenerative disease characterized by a disruption of articular joint cartilage homeostasis. Mice are the most commonly used models to study OA. Despite recent reviews, there is still a lack of knowledge about the new development in imaging techniques. Two types of modalities are complementary: those that assess structural changes in joint tissues and those that assess metabolism and disease activity. Micro MRI is the most important imaging tool for OA research. Automated methodologies for assessing periarticular bone morphology with micro-CT have been developed allowing quantitative assessment of tibial surface that may be representative of the whole OA joint changes. Phase-contrast X-ray imaging provides in a single examination a high image precision with good differentiation between all anatomical elements of the knee joint (soft tissue and bone). Positron emission tomography, photoacoustic imaging, and fluorescence reflectance imaging provide molecular and functional data. To conclude, innovative imaging technologies could be an alternative to conventional histology with greater resolution and more efficiency in both morphological analysis and metabolism follow-up. There is a logic of permanent adjustment between innovations, 3R rule, and scientific perspectives. New imaging associated with artificial intelligence may add to human clinical practice allowing not only diagnosis but also prediction of disease progression to personalized medicine.

INTRODUCTION: No recent national guidelines exist regarding the management of urinary tract infections (UTIs) in the presence of ureteral stent. This situation could lead to discrepancies in clinical management and less opportunity for a favorable patient's outcome. METHODS: All available data published on Medline® between 1998 and 2018 were systematically searched and reviewed. All papers assessing adult patients carrying ureteral stent were included for analysis. After studies critical analysis, national guidelines for clinical management were elaborated in order to answer clinical questions. RESULTS: A total of 451 articles were identified, of which 58 have been included. The prevalence of urinary tract infections in the presence of ureteral stent remains unknown. After 3 months, all endo-ureteral devices were colonized on microbiological study. These patients also presented a positive urine culture in 25 to 70% of the cases, often polymicrobial. Staphylococci, E. coli, Klebsiella, Pseudomonas, Enterococcus and Candida were the commonest micro-organisms responsible for urinary colonization or infection. The risk of UTI on endo-ureteral devices seemed higher the longer it stayed implanted. There is no justification in the literature to recommend a systematic change of endo-ureteral devices following a urinary tract infection. DISCUSSION: The existing literature is rich but of poor methodological quality, and therefore does not allow to draw robust conclusions. The greatest difficulty faced in this work was to accurately differentiate urinary colonizations from true infections, including clinical symptoms and not only microbiological results. CONCLUSION: These guidelines propose a standardized management of such common clinical situations. Well-designed studies are needed to upgrade the level of evidence of these guidelines.

INTRODUCTION: Notwithstanding high prevalence of presumably bacterial infections in elderly persons (EP) in palliative care (PC), there exists no recommendation on the role of antibiotic therapy (ABP) in this type of situation. OBJECTIVE: To describe the determinants of antibiotic prescription by general practitioners (GP) and by doctors practicing in institutions (DPI) for patients>75 years, in end-of-life situations in PC. METHOD: Descriptive investigation by anonymous self-administered questionnaire disseminated in France by e-mail. RESULTS: A total of 301 questionnaires analyzed: 113 GP, 188 DPIs. The latter were mainly geriatricians (69, 36.6%) and infectologists/internists (41, 21.8%). Sixty-three (55,75%) GPs and 144 (78.7%) DPIs stated that they had prescribed antibiotics. Practice in "EHPAD" retirement homes or intensive care was often associated with non-prescription of antibiotics. Age, PC training and number of patients monitored bore no influence. Family involvement in decision-making was more frequent for GPs than for DPIs. The main purpose of antibiotic therapy was to relieve different symptoms (fever, respiratory congestion, functional urinary signs). Most of the doctors (81%) had previously encountered complications (allergy, adverse effect), which represented the main causes of treatment discontinuation. CONCLUSION: Antibiotic use in end-of-life EPs in PC seems frequent. In accordance with the principle of beneficence, its goal of often symptom-related; that said, in the absence of scientific data, antibiotic prescription in end-of-life situations should be individualized in view of observing the other ethical caregiving principles (beneficence, non-maleficence, justice, patient autonomy) and re-evaluated daily.

Previous studies have evidenced cognitive difficulties across various domains in Type 1 Diabetes Mellitus (T1DM) children, but the implicit memory system has not yet been systematically explored.Taking into account that the interplay between memory and perception may be modulated by the semantic category of the stimuli and their salience, we explored explicit and implicit memory using both object and food stimuli to verify whether for T1DM children there is a feebleness in performing the function of memory as a function of the stimuli used.Eighteen T1DM children and 47 healthy children performed an explicit recognition task in which they were requested to judge whether the presented image had already been shown ("old") or not ("new") and an identification priming task in which they were asked to name new and old pictures presented at nine ascending levels of spatial filtering.Results did not reveal any differences between controls and T1DM children in the explicit memory recognition task, whereas some differences between the two groups were found in the identification priming task. In T1DM children, the priming effect was observed only for food images.The dissociation between implicit and explicit memory observed in children with diabetes seems to be modulated by the category of the stimuli, and these results underscore the relevance of taking into account this variable when exploring cognitive functions.

Malnutrition remains a particularly important issue in elderly. Physiological ageing induces many changes but ageing cannot entirely explain a Protein-Energy Malnutrition (PEM). Nutritionnal screening is indicated once a year in community medicine or in the first 48hours in case of an acute disease or of hospitalization. The Mini Nutritional Assessment is recommended for screening and for the diagnostic of malnutrition. Possible aetiologies are large and must be investigated in order to be careful not to dismiss curable disease and to be able to take corrective actions. PEM is associated to functional decline, length of stay in hospital and to morbi-mortality. Recommendations for dietary intakes in healthy old subjects are about 30 kcal/kg/day and 1 g/kg/day of protein and are strongly enhanced in case of acute or chronic diseases. The nutritional strategy depends on spontaneous food intake, medical situation, patient profile and opinion. Appropriate nutritional care could reduce morbidity-mortality and prevent functional decline in various disease contexts.

OBJECTIVES: The aim was to describe the impact of infective endocarditis (IE) on functional, cognitive and nutritional statuses, and to estimate the influence of these parameters on surgical management and mortality. METHOD: This was a prospective study over 13 months in 14 French hospitals, including patients ≥75 years of age with definite or possible IE. A comprehensive geriatric assessment (CGA) was performed during the first week of hospitalization, including a retrospective estimation of functional status 2 months before hospitalization, and 3 months after. RESULTS: A total of 120 patients were included (mean age 83.1 ± 5.0 (75-101) years). IE was associated with a dramatic impairment of functional status between 2 months prior hospitalization and the first geriatric evaluation (90.8% able to walk vs. 35.5% (p < 0.0001), ADL (Activities in Daily Living) 5.0 ± 1.7 vs. 3.1 ± 2.1 (p < 0.0001)). The 19 operated patients (15.8%) had less comorbidities (cumulative illness rating scale geriatric 10.8 ± 8.2 vs. 15.3 ± 7.1 (p 0.0176)), better functional (ADL 5.9 ± 0.4 vs. 4.9 ± 1.8 (p 0.0171) and nutritional (mini nutritional assessment 20.4 ± 5.0 vs. 17.3 ± 6.2 (p 0.0501)) statuses than non-operated patients. Among all infectious, cardiac and geriatric parameters, body mass index (HR 0.9, range 0.8-1, p 0.05) and ADL at the time of the first evaluation (HR 0.7, range 0.6-0.9, p 0.002) were the sole independent predictors of the 3-month (32.5%) and 1-year mortality (42.5%). Three months later, the 57 assessed patients only partially recovered their ADL (3.7 ± 1.9 vs. 5.3 ± 1.4 2 months prior hospitalization and 4.6 ± 1.9 at the first CGA; p < 0.0001). CONCLUSION: Functional and nutritional abilities are crucial components that can be accurately explored through a CGA when managing IE in oldest patients.

BACKGROUND: Antimicrobials are among the most frequently prescribed drugs in long-term care facilities (LTCFs). Implementation of antimicrobial stewardship programmes (ASPs) is often challenging because of scarce data in this setting. OBJECTIVES: This narrative review aimed to provide data about antibiotic consumption in LTCFs and the need, implementation, and organization of ASPs in this setting. SOURCE: PubMed was searched for studies assessing antimicrobial consumption and implementation of ASPs in LTCFs. The search was restricted to articles published in English in the last 10 years. Experts belonging to the ESCMID Study Group for Infections in the Elderly (ESGIE) reviewed the selected studies and evaluated the studies on ASPs according to the GRADE approach. Moreover, the quality of reporting has been assessed according to TREND and CONSORT checklists for quasi-experimental and cluster randomized clinical trials (cRCT), respectively. CONTENT: Data on antibiotic consumption in LTCFs show great variability in LTCFs across and within countries. Reasons for this variability are difficult to analyse because of the differences in the types of LTCFs, their organization, and the population cared-for in the different LTCFs. However, studies show that the use of antibiotics among elderly patients in LTCFs, especially in cases of asymptomatic bacteriuria and influenza-like syndromes, is often inappropriate. High-quality cRCTs and low to moderate quality quasi-experimental studies show that educational interventions direct at nurse and physicians are effective in reducing unnecessary antibiotic prescriptions. IMPLICATIONS: There is an urgent need for ASPs tailored for LTCFs. Multifaceted organized educational interventions, involving both clinicians and nursing staff, should be advocated and require institutional intervention by health authorities. Future studies assessing the impact of well-defined ASPs in LTCFs should produce compelling evidence in this setting.

Osteoarthritis (OA) is a degenerative chronic disease affecting >300,000 million people around the world as of 2016. Symptomatic measures exist, but there are hardly any curative treatments available. Disruption of the cartilage homeostasis in favor of catabolism leads to cartilage destruction. ROS-macromolecular-induced damage is significantly greater in OA cartilage and OA is described as low-grade chronic systemic inflammation. This review aimed to assess the critical role of cartilage ageing and oxidative stress in the OA process, focusing in particular on NADPH oxidase and especially Nox4 involvement. With age, hypertrophic senescent cells with an altered redox cell profile accumulated. Chondrocytes are more sensitive to oxidant-mediators and the serum level of pro-inflammatory mediators increases. Age-related advanced glycation end products impact on extra cellular matrix (ECM) properties leading to the apoptosis of chondrocytes. A focus on NADPH oxidase-mediated-ROS signaling highlighted the very specific Nox4 isoform, which plays a role on the final common pathway targeting chondrocyte cells. IL-1ß-mediated Nox4 stimulation induced an increase in the levels released by the chondrocyte of MMP-1 and MMP-13 proteins, which are involved in ECM degradation. In comparison with the other Nox isoforms, Nox4 remains unusual, since it is constitutively active, does not depend on cytosolic activator proteins and seems to generate H2O2 thanks to the specific conformation of the Nox4 E-loop. Nox4-induced ROS production appears an essential actor in the OA process and it could be relevant to focus on this target in the aim of discovering and developing new therapeutic strategies.

Electrophysiological and neuroimaging studies suggest that our actions are initiated by unconscious mental processes long before awareness of intention to act. The time window between the awareness of the intention to move and the movement onset, which normally permits to exert a conscious "veto" on the impending action, is modulated by individual differences in trait impulsivity. In particular, trait impulsive people show a delayed awareness of the intention to act, probably exceeding the "point of no return", after which the action can no longer be inhibited. In order to investigate if individual differences in the "veto" interval might be explained by differences in the readiness potential (RP) dynamics, nineteen healthy participants underwent an impulsivity trait assessment using the Barratt Impulsiveness Scale (BIS-11) and performed a task based on Libet's clock paradigm, during EEG recordings of pre-movement neural activity. We observed a positive relationship between impulsive personality trait and motor system excitability during the preparation of self-initiated movements. In particular, the RP showed an earlier negative rising phase and a greater amplitude, with the increasing of BIS-11 scores. Based on present results, we conclude hypothesizing that trait impulsivity might be characterized by less effective preparatory inhibition mechanisms, which have a fundamental role in the control of behavior.

OBJECTIVE: To assess the incidence of pertussis (whooping cough) in subjects aged 50years and older in France. METHODS: Participating family physicians (FPs) using the patient record management software AxiSanté® included patients aged 50years and older, who had signed an informed consent form, presenting with persistent cough for 7 to 21days. Bordetella genetic material was detected by polymerase chain reaction (PCR) on nasopharyngeal samples collected at the FP's discretion. RESULTS: A total of 42 FPs included 129 patients from June 2013 to August 2014 (large cities: 38; medium-sized cities: 57; rural areas: 34); 106 samples were analyzed. Overall, 30 pertussis cases were diagnosed: 10 cases confirmed by PCR, 18 purely clinical cases, and two direct epidemiological cases. The crude incidence rate per 100,000 patients aged≥50years was 103.6 (95% CI: 69.9-47.9): 77.1 in large cities, 103.1 in medium-sized cities, and 143.9 in rural areas. The extrapolated incidence rate per 100,000 persons aged≥50years was 187.1 (95% CI: 126.2-67.1): 131.1 in large cities, 256.1 in medium-sized cities, and 242.2 in rural areas. CONCLUSION: The population aged 50years and older can serve as a reservoir. Its role in Bordetella pertussis circulation should be taken into account for pertussis booster vaccination programs.

BACKGROUND: During prosthetic joint infection (PJI), surgical management is sometimes impossible and indefinite chronic oral antimicrobial suppression (ICOAS) may be the only option. The outcomes of elderly patients who benefited from ICOAS with strictly palliative intent were evaluated. METHODS: A national retrospective cohort study was performed in France, involving patients aged >75 years with a PJI who were managed with planned life-long ICOAS from 2009 to 2014. Patients who experienced an event were compared to those who did not. An event was defined as a composite outcome in patients undergoing ICOAS, including local or systemic progression of the infection, death, or discontinuation of antimicrobial therapy because of an adverse drug reaction. RESULTS: Twenty-one patients were included, with a median age of 85 years (interquartile range 81-88 years). Eight of the 21 patients experienced an event: one had an adverse drug reaction, three had systemic progression of sepsis, and two had local progression. Two of the 21 patients died. No death was related to ICOAS or infection. There was no significant difference between the population with an event and the population free of an event with regard to demographic, clinical, and microbiological characteristics (p>0.05). CONCLUSIONS: ICOAS appeared to be an effective and safe option in this cohort.

During prosthetic joint infection (PJI), optimal surgical management with exchange of the device is sometimes impossible, especially in the elderly population. Thus, prolonged suppressive antibiotic therapy (PSAT) is the only option to prevent acute sepsis, but little is known about this strategy. We aimed to describe the characteristics, outcome and tolerance of PSAT in elderly patients with PJI. We performed a national cross-sectional cohort study of patients >75 years old and treated with PSAT for PJI. We evaluated the occurrence of events, which were defined as: (i) local or systemic progression of the infection (failure), (ii) death and (iii) discontinuation or switch of PSAT. A total of 136 patients were included, with a median age of 83 years [interquartile range (IQR) 81-88]. The predominant pathogen involved was Staphylococcus (62.1%) (Staphylococcus aureus in 41.7%). A single antimicrobial drug was prescribed in 96 cases (70.6%). There were 46 (33.8%) patients with an event: 25 (18%) with an adverse drug reaction leading to definitive discontinuation or switch of PSAT, 8 (5.9%) with progression of sepsis and 13 died (9.6%). Among patients under follow-up, the survival rate without an event at 2 years was 61% [95% confidence interval (CI): 51;74]. In the multivariate Cox analysis, patients with higher World Health Organization (WHO) score had an increased risk of an event [hazard ratio (HR) = 1.5, p = 0.014], whereas patients treated with beta-lactams are associated with less risk of events occurring (HR = 0.5, p = 0.048). In our cohort, PSAT could be an effective and safe option for PJI in the elderly.

Deficient voluntary control of behaviour and impulsivity are key aspects of impulse control disorders. The objective of the present study was to evaluate the relationship between behavioural measures of impulsivity and the awareness of voluntary action. Seventy-four healthy volunteers completed the Barratt Impulsiveness Scale (BIS), a questionnaire used to measure impulsive personality traits, and a go/no-go task. Moreover, all participants performed a behavioural task based on the Libet's clock paradigm in which they were requested to report the time of a self-initiated movement (M-judgement) or the time they first feel their intention to move (W-judgement). A positive relationship between the time in which subjects reported the intention to move (W-judgement) and impulsivity measures emerged. Namely, the higher was the score in the attentional and motor impulsivity subscales of the BIS and the number of inhibitory failure responses in the go/no-go task, the lower was the difference between the W-judgement and the actual movement (i.e. the awareness of intention to move was closer to the voluntary movement execution). In contrast, no relationship emerged with M-judgement. The present findings suggest that impulsivity is related to a delayed awareness of voluntary action. We hypothesize that in impulse control disorders, the short interval between conscious intention and actual movement may interfere with processes underlying the conscious 'veto' of the impending action.

Cytomegalovirus (CMV) gastrointestinal disease rarely occurs in immunocompetent patients, and is mainly diagnosed on the basis of histopathological findings. Real-time PCR for CMV DNA quantification is considered to be a useful diagnostic tool, but its place in the diagnostic strategy is not clearly defined. The goal of the study was to describe the clinical and paraclinical features of apparently immunocompetent patients with CMV gastrointestinal disease diagnosed according to quantitative PCR results. In this retrospective study conducted in a 1500-bed tertiary-care centre, we reviewed the case records of apparently immunocompetent patients with positive findings of CMV DNA in gastrointestinal biopsies with compatible symptoms and endoscopic findings. A total of 13 patients were included between January 2007 and December 2010. The median age was 81 years, and 54% of patients had underlying immune-modulating conditions. Diarrhoea, haematochezia and dysphagia were the main reported symptoms, and ulcers were the main endoscopic findings. The mean value of CMV DNA load in gastrointestinal biopsies was 3845 copies/µg total DNA (range, 15-15 500 copies/µg total DNA). The highest values were found in two patients who were diagnosed with adenocarcinoma in the subsequent course of CMV infection. Clinical features were similar to those in previous series in which diagnosis was based on histopathological analysis. Elderly people are more commonly affected, and a link with immune senescence is possible. Quantification of CMV DNA seems to be a useful tool for diagnosis when combined with clinical and endoscopic findings, but further studies are necessary to interpret quantitative values.

A national survey was performed to explore antibiotic prescription by the subcutaneous (sc) route among French infectious diseases and geriatric practitioners. Among the participating physicians, 367 (96.1%) declared administering sc antibiotics at some point. Ceftriaxone was prescribed sc by all but one, and ertapenem, teicoplanin, aminoglycosides and amoxicillin by 33.2%, 39.2%, 35.1% and 15.3%, respectively. The sc route was resorted to mainly in case of unavailable oral, intravenous or intramuscular routes, especially during palliative care. Pain, skin necrosis and lack of efficacy were the main adverse effects, reported by 70.8%, 12.8% and 19.9% of practitioners, respectively. Further studies are needed to precise the indications, modalities and tolerance of sc antibiotic use.

INTRODUCTION: One percent of falls in over-75 years old cause hip fracture (HF). Protein-energy malnutrition (PEM) is associated with falls and fracture. PEM screening and perioperative nutritional management are recommended by the European Society of Parenteral and Enteral Nutrition, yet data on nutritional status in elderly HF patients are sparse. The Mini Nutritional Assessment (MNA) score is presently the most effective screening tool for PEM in over-75 years old. OBJECTIVE: The principal objective of the present study was to determine the prevalence on MNA of PEM in patients aged over 75 years admitted for HF. Secondary objectives were to identify factors associated with PEM and its role as a factor of evolution. MATERIALS AND METHODS: A prospective observational epidemiological study included 50 patients aged over 75 years admitted for HF in an 8-bed orthopedic surgery department with a geriatric follow-up unit. PEM was defined by MNA<17/30. Assessment systematically comprised associated comorbidity (Cumulative Illness Rating Scale-Geriatric [CIRS-G]), cognitive status on the Mini Mental State Examination (MMSE), functional status on activities of daily life (ADL), and mean hospital stay (MHS). Scores were compared on quantitative tests (Student t) with the significance threshold set at P<0.05. RESULTS: Mean age for the 50 patients was 86.1 years (range, 77-94 years). Prevalence of PEM was 28%; a further 58% of patients were at risk for PEM. PEM was associated with elevated CIRS-G (P<0.006), greater numbers of severe comorbidities (P=0.006), more severe cognitive disorder (P=0.005) and functional dependence (P=0.002), and 8 days' longer MHS (P=0.012). DISCUSSION: The present study confirmed the high prevalence of PEM in HF patients aged over 75 years, supporting longer hospital stay. MNA is a diagnostic gold standard, not to be replaced by albuminemia or body-mass index in this perioperative clinical situation. Given the present economic stakes relating to geriatric trauma patients' hospital stay, it is essential to prevent, diagnose and treat PEM in elderly subjects. LEVEL OF EVIDENCE: Level IV; prospective cohort study.
