RESUMO
BACKGROUND: Compared with conventional hospitalization, admission to an acute geriatric care unit (AGU) is associated with better outcomes in elderly patients. In 2012, 50% of the hospitalizations of elderly patients were preceded by an emergency department (ED) visit. Hospital occupancy, access blocks and overcrowding experienced by patients during ED visits are associated with increased morbidity. OBJECTIVE: Our aim was to evaluate the effect of direct admission (DA) to an AGU on both the hospital length of stay and morbidity of elderly patients. DESIGN: This study was a retrospective cohort study conducted using electronic medical records and administrative claims data from the Greater Paris University Hospitals (APHP) health data warehouse involving 19 different AGUs. PARTICIPANTS: We included all patients ≥ 75 years old who were admitted to an AGU for more than 24 h between January 1, 2013, and December 31, 2018. INTERVENTION: Direct admission to the AGU compared to admission after an ED visit. MAIN MEASURES: The main outcome was hospital length of stay. Two outcomes were used to analyse morbidity: postacute care and rehabilitation ward transfer at the end of the index hospitalization and ED return visit within 30 days after the index hospitalization (for those who survived to hospitalization). We used an inverse probability of treatment weighting (IPTW) approach to balance the differences in patient baseline variables between the two groups. Univariate linear and logistic regression models were built to estimate the effect of DA on hospital length of stay and the likelihood of postacute care transfer and ED return visit. KEY RESULTS: Among the 6583 patients included in the study, DA was associated with a lower hospital length of stay (estimate = -1.28; 95% CI = -1.76-0.80), and a lower likelihood of postacute care transfer (OR = 0.87; 95% CI = 0.77-0.97). It was not significantly associated with a lower risk of ED return visits (OR = 0.81; 95% CI = 0.60-1.08) in the following month. CONCLUSION: DA should be prioritized, and reorganization of the geriatric pathway around DA should be encouraged due to the frailty of elderly individuals.

Calprotectin and lactoferrin are released by the gastrointestinal tract in response to infection and mucosal inflammation. Our objective was to assess the usefulness of quantifying faecal lactoferrin and calprotectin concentrations in Clostridium difficile infection (CDI) patients with or without free toxins in the stools. We conducted a single-centre 22-month case-control study. Patients with a positive CDI diagnosis were compared to two control groups: group 1 = diarrhoeic patients negative for C. difficile and matched (1:1) to CDI cases on the ward location and age, and group 2 = diarrhoeic patients colonised with a non-toxigenic strain of C. difficile. Faecal lactoferrin and calprotectin concentrations in faeces were determined for patients with CDI and controls. Of 135 patients with CDI, 87 (64.4%) had a positive stool cytotoxicity assay (free toxin) and 48 (35.6%) had a positive toxigenic culture without detectable toxins in the stools. The median lactoferrin values were 26.8 µg/g, 8.0 µg/g and 15.8 µg/g in CDI patients and groups 1 and 2, respectively. The median calprotectin values were 218.0 µg/g, 111.5 µg/g and 111.3 µg/g, respectively. Among patients with CDI, faecal lactoferrin and calprotectin levels were higher in those with free toxins in their stools (39.2 vs. 10.2 µg/g, p = 0.003 and 274.0 vs. 166.0 µg/g, p = 0.051, respectively). Both faecal calprotectin and lactoferrin were higher in patients with CDI, especially in those with detectable toxin in faeces, suggesting a correlation between intestinal inflammation and toxins in stools.

We explored age-dependent patterns in haemagglutination inhibition (HI) titre to seasonal [1956 A(H1N1), 1977 A(H1N1), 2007 A(H1N1)] and pandemic [A(H1N1)pdm09] influenza strains using serological data collected from an adult French influenza cohort. Subjects were recruited by their general practitioners from 2008 to 2009 and followed until 2010. We explored age-related differences between strain-specific HI titres using 1053 serological samples collected over the study period from 398 unvaccinated subjects. HI titres against the tested seasonal and pandemic strains were determined using the HI technique. Geometric mean titres (GMTs) were estimated using regression models for interval-censored data. Generalized additive mixed models were fit to log-transformed HI estimates to study the relationship between HI titre and age (age at inclusion and/or age at initial strain circulation). GMT against one strain was consistently highest in the birth cohort exposed to that strain during childhood, with peak titres observed in subjects aged 7-8 years at the time of initial strain circulation. Our results complete previous findings on influenza A(H3N2) strains and identify a strain-dependent relationship between HI titre and age at initial strain circulation.

BACKGROUND: The public health burden resulting from infectious diseases requires efforts in surveillance and evaluation of health care. The use of administrative health databases (AHD) and in particular the French national health insurance database (SNIIRAM) is an opportunity to improve knowledge in this field. The SNIIRAM data network (REDSIAM) workshop dedicated to infectious diseases conducted a narrative literature review of studies using French AHD. From the results, benefits and limits of these new tools in the field of infectious diseases are presented. METHODS: Publications identified by the members of the workgroup were collected using an analytical framework that documented the pathology of interest, the aim of the study, the goal of the developed algorithm, the kind of data, the study period, and the presence of an evaluation or a discussion of the performance of the performed algorithm. RESULTS: Fifty-five articles were identified. A majority focused on the field of vaccination coverage and joint infections. Excluding vaccine coverage field, the aim of 28 studies was epidemiological surveillance. Twenty-six studies used hospital databases exclusively, 18 used ambulatory databases exclusively and 4 used both. Validation or discussion of the performed algorithm was present in 18 studies. CONCLUSIONS: The literature review confirmed the interest of the French AHD in the infectious diseases field. The AHD are additional tools of the existing surveillance systems and their use will probably be more frequent in the coming years given their advantage and reliability. However, incoming users need to be assisted. Thus, the workgroup will contribute to a reasonable use of AHD and support future developments.

Controversies over the effectiveness and safety of the pandemic influenza A(H1N1)pdm09 vaccine in 2009/10 may have altered the influenza vaccination coverage in France after the pandemic season. The purpose of this study was to determine whether the pandemic affected seasonal influenza vaccination behaviours in the general population by analysing vaccination behaviours from 2006/07 to 2011/12 among the 1,451 subjects of the Cohort for Pandemic Influenza (CoPanFlu) France.We found that vaccination behaviours in 2010/11 and 2011/12 significantly differed from behaviours before the pandemic, with the notable exception of the targeted risk groups for seasonal influenza-related complications. Among the population with no risk factors,the post-pandemic influenza vaccine coverage decreased, with people aged 15 to 24 years and 45to 64 years being most likely to abandon vaccination.Therefore, this study documents a moderate negative effect of the 2009/10 pandemic episode on vaccination behaviours in the French metropolitan population that was apparent also in the following two seasons.Moreover, it does not exclude that the general trend of reduced vaccination has also affected certain targeted groups at high risk for complications.

Japanese encephalitis vaccine (Jevax) is an inactivated vaccine using the Nakayama viral strain. Until 2007, Jevax was the only Japanese encephalitis vaccine available in France but the duration of seroprotection after vaccination and exact timing of booster injections was unclear for travelers from non-endemic areas. The purpose of this report is to describe the results of a retrospective study in which neutralizing antibody levels were measured in 71 subjects previously vaccinated with Jevax. All subjects underwent testing at the Pasteur Institute Medical Center as part of preparation for humanitarian missions to endemic Japanese encephalitis areas in 2005-2006. A neutralizing antibody level greater than or equal to 20 was considered as protective. Findings showed that 49 of the 71 subjects (69%) still had protective antibody levels at a median of 4 years after the last Jevax immunization. In multivariate analysis, the only factor correlated with long-term seroprotection was the total number of vaccinations received. Based on these findings, it was concluded that long-term seroprotection after Jevax vaccination requires repeated booster injections even in subjects frequently exposed to the virus. No correlation was found between seroprotection and the interval between the booster injections.

BACKGROUND: Stigma associated with depression and antidepressants is strong among the general population but also among patients and health professionals. OBJECTIVES: This cross-sectional study is aimed at: 1) evaluating the knowledge and attitude towards antidepressant by nursing student; 2) exploring the association between instruction in psychiatry and representation of depression and antidepressants. PARTICIPANTS: 2037 undergraduate students from 10 French nursing schools were invited to participate in 2017, 1475 (73%) completed the questionnaire. METHODS: The self-report questionnaire included the Drug Attitude Inventory (DAI) and questions about representation on depression and antidepressant. Four groups of students were built: 1) pre-teaching group (PT) as a reference group, 2) clinical training in psychiatry (CT), 3) receiving mental health theoretical education (TE), 4) receiving both (CT + TE). RESULTS: The mean (standard deviation) DAI score was negative: -1.9 (±4.4) with only 40% of the nursing students conveying a positive attitude towards antidepressant. A combination of CT and TE was associated with a more positive attitude towards antidepressant in comparison with the PT condition. The CT + TE group was more prone to view antidepressants as effective and safe. CONCLUSION: There is strong stigma against depression/antidepressants among nursing student. Education combined with clinical experiences in psychiatry improved these representations.

INTRODUCTION: Dengue fever is the main emerging vector-borne disease worldwide. It was estimated that 40% of the world population is at risk. A potential vector (Aedes albopictus) is present in four French departments of the southeast area of metropolitan France. METHOD: The authors tried to document the number of imported cases of dengue diagnosed from 2001 to 2006, inclusive, as well as their main features. RESULTS: Between 12 and 28 cases of imported dengue were diagnosed every month during that period (eight to 18 cases per month except for years 2001-2002 during which an important dengue epidemic was documented in the French West Indies). Nearly 40% of the cases were imported between June and September during which the vector is active in the metropolitan area. CONCLUSION: This data underlines the strong and close link between the endemic zones of the French territory (French West Indies and Guyana) and the risk of imported cases to metropolitan France. The identification of this "importation track" entails strengthening the system for detecting and managing imported dengue cases in metropolitan France when a dengue epidemic is detected in the French West Indies.

Weight loss is reported by more than 20% of hepatitis C virus (HCV)-monoinfected patients treated with the peg-interferon (peg-IFN) and ribavirin combination. The aim of this study was to determine the incidence and risk factors of severe weight loss (> or =10%) in human immunodeficiency virus (HIV) / HCV-coinfected patients participating in a randomized, controlled 48-week trial comparing peg-IFN alpha 2b plus ribavirin with IFN alpha-2b plus ribavirin. Univariate and multivariate analyses were used to identify links with antiretroviral treatments, anti-HCV therapy and clinical and laboratory findings. One hundred eleven (28.9%) of 383 patients who received at least one dose of anti-HCV treatment subsequently had severe weight loss. Among patients who took at least 80% of the planned total dose, severe weight loss occurred in 74 patients (32.7%). In multivariate analysis, age >40 years [hazard ratio (HR), 1.59; 95% CI 1.09 to 2.31; P = 0.016], body mass index (BMI) >22 (HR, 1.72; 95% CI, 1.16 to 2.55; P = 0.0069), peg-IFN alpha-2b (HR, 1.82; 95% CI, 1.24 to 2.69; P = 0.0022) and female sex (HR, 1.60; 95% CI, 1.05 to 2.43; P = 0.027) were associated with severe weight loss. In contrast, patients taking non-nucleoside reverse transcriptase inhibitors (NNRTI)-containing antiretroviral regimens were less likely to lose weight (HR, 0.62; 95% CI, 0.39 to 0.96; P = 0.034). Lipodystrophy tended to occur more frequently in patients who had severe weight loss than in the other patients (26.1%vs 17.6%; P = 0.0682) and patients whose weight loss >5% persisted 24 weeks after the completion of anti-HCV therapy (n = 58 / 111) were more likely to be receiving stavudine-based antiretroviral therapy, suggesting that mitochondrial toxicity plays some role in weight loss. These findings show that severe weight loss is a frequent side effect of anti-HCV therapy in HIV / HCV-coinfected patients. The underlying mechanisms remain to be identified.

Schizophrenia is a severe mental condition in which several lipid abnormalities-either structural or metabolic-have been described. We tested the hypothesis that an abnormality in membrane lipid composition may contribute to aberrant dopamine signaling, and thereby symptoms and cognitive impairment, in schizophrenia (SCZ) patients. Antipsychotic-medicated and clinically stable SCZ outpatients (n=74) were compared with matched healthy subjects (HC, n=40). A lipidomic analysis was performed in red blood cell (RBC) membranes examining the major phospholipid (PL) classes and their associated fatty acids (FAs). Clinical manifestations were examined using the positive and negative syndrome scale (PANSS). Cognitive function was assessed using the Continuous Performance Test, Salience Attribution Test and Wisconsin Card Sorting Test. Sphingomyelin (SM) percentage was the lipid abnormality most robustly associated with a schizophrenia diagnosis. Two groups of patients were defined. The first group (SCZ c/SM-) is characterized by a low SM membrane content. In this group, all other PL classes, plasmalogen and key polyunsaturated FAs known to be involved in brain function, were significantly modified, identifying a very specific membrane lipid cluster. The second patient group (SCZ c/SM+) was similar to HCs in terms of RBC membrane SM composition. Compared with SCZ c/SM+, SCZ c/SM- patients were characterized by significantly more severe PANSS total, positive, disorganized/cognitive and excited psychopathology. Cognitive performance was also significantly poorer in this subgroup. These data show that a specific RBC membrane lipid cluster is associated with clinical and cognitive manifestations of dopamine dysfunction in schizophrenia patients. We speculate that this membrane lipid abnormality influences presynaptic dopamine signaling.

French Healthcare Networks aim to help healthcare workers take care of patients by improving co-operation, co-ordination and the continuity of care. When applied to palliative care in the home, they facilitate overall care, including medical, social and psychological aspects. French legislation in 2002 required that an information document explaining the functioning of the Network should be given to patients when they enter a Healthcare Network. Ethical problems arise from this legislation with regard to providing terminal patients with explicit information upon their entry into the palliative phase of the disease, and requiring them to sign the document. It highlights the limitations of this practice, and the gap between the legislation and the nature of the physician-patient relationship in palliative care.
