Clinical effectiveness of influenza vaccination after allogeneic hematopoietic stem cell transplantation: A cross-sectional prospective observational…
2018
Abstract Background Vaccination is the primary method for preventing influenza respiratory virus infection (RVI). Although the influenza vaccine is able to achieve serological responses in some allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients, its clinical benefits are still uncertain. Methods In this prospective, cross-sectional study, we retrospectively analyzed the effect of inactivated trivalent influenza vaccination on the prevalence of influenza RVI in a consecutive cohort of 136 allo-HSCT adult recipients who developed 161 RVI over 5 flu seasons (from 2013 to 2018). Respiratory viruses in upper– and/or lower–respiratory tract specimens were tested using multi…
Low Dietary Magnesium and Overweight/Obesity in a Mediterranean Population: A Detrimental Synergy for the Development of Hypertension. The SUN Project
2020
Hypertension is the strongest independent modifiable risk factor for cardiovascular disease. We aimed to investigate the association of magnesium intake with incident hypertension in a Mediterranean population, and the potential modification of this association by body mass index BMI. We assessed 14,057 participants of the SUN (Seguimiento Universidad de Navarra) prospective cohort (67.0% women) initially free of hypertension. At baseline, a validated 136-item food frequency questionnaire was administered. We used Cox models adjusted for multiple socio-demographic, anthropometric, and lifestyle factors, and prevalent conditions present at baseline. Among a mean 9.6 years of follow-up we obs…
Delivery of oral nutrition supplement in hospital: Evaluation of professional practices in evaluation of nutritional status and representations of ON…
2020
Journal non répertorié dans le JCR.; International audience; BACKGROUND: Nutritional evaluation and detection of malnutrition are based on criteria recommended by French health authorities. In practice, doctors do not always ensure strict implementation of the recommendations. The aim of this study is to evaluate professional practices in France regarding nutritional follow-up on arrival, during and after the hospitalization of inpatients who have oral nutritional supplements (ONS) prescribed and to discuss how ONS are seen by medical staff and patients. METHODS: A prospective study including patients consecutively admitted to digestive surgery and endocrinology units of the Dijon universit…
Identification of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome-associated DNA methylation patterns.
2018
BackgroundMyalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a complex condition involving multiple organ systems and characterized by persistent/relapsing debilitating fatigue, immune dysfunction, neurological problems, and other symptoms not curable for at least 6 months. Disruption of DNA methylation patterns has been tied to various immune and neurological diseases; however, its status in ME/CFS remains uncertain. Our study aimed at identifying changes in the DNA methylation patterns that associate with ME/CFS.MethodsWe extracted genomic DNA from peripheral blood mononuclear cells from 13 ME/CFS study subjects and 12 healthy controls and measured global DNA methylation by EL…
Assessment of prevalence and load of torquetenovirus viraemia in a large cohort of healthy blood donors.
2020
OBJECTIVES: Torquetenovirus (TTV) is an emerging marker of functional immune competence with the potential to predict transplant-related adverse events. A large-scale epidemiological study was performed to understand how basal values vary in healthy individuals according to age and gender.; METHODS: We tested plasma from 1017 healthy blood donors aged 18-69years. The presence and load of TTV were determined by a real-time PCR assay. A sub-cohort of 384 donors was tested for anti-cytomegalovirus IgG antibodies, and 100 participants were also tested for TTV viraemia on a paired whole blood sample.; RESULTS: The overall prevalence of TTV was 65% (657/1017) with a mean (±SD) growth of 5±4% ever…
(1,3)-β-d-Glucan-based antifungal treatment in critically ill adults at high risk of candidaemia: an observational study.
2016
OBJECTIVES To determine the effects of a strategy that uses serum (1,3)-β-d-glucan (BDG) results for antifungal treatment of ICU patients at high risk of invasive candidiasis. PATIENTS AND METHODS Adult patients admitted to the ICU from January 2012 to June 2014 were included if they exhibited sepsis at the time of BDG testing and they met Candida score components ≥3. A retrospective analysis of collected data was performed. RESULTS In total, 198 patients were studied. Of 63 BDG-positive patients, 47 with candidaemia and 16 with probable Candida infection, all [31.8% (63/198)] received antifungal therapy. Of 135 BDG-negative patients, 110 [55.5% (110/198)] did not receive antifungal therapy…
No effect of vancomycin MIC ≥ 1.5 mg/L on treatment outcome in methicillin-susceptible Staphylococcus aureus bacteraemia
2018
International audience; The vancomycin minimum inhibitory concentration (MIC) has been shown to affect the outcome of methicillin-susceptible Staphylococcus aureus (MSSA) bacteraemia. In this study, the outcomes of patients with MSSA bacteraemia with a vancomycin MIC ≥ 1.5 mg/L were assessed. A prospective cohort of patients with MSSA bacteraemia in two tertiary-care hospitals was collected. The vancomycin MIC was determined by Etest. Staphylococcus aureus strains were categorised as low (<1.5 mg/L) or high (≥1.5 mg/L) vancomycin MIC. First- and second-line treatments were recorded and classified as optimal, appropriate and inappropriate. The primary endpoint was 30-day mortality. A total o…
The clinical impact of PCR‐based point‐of‐care diagnostic in respiratory tract infections in children
2020
Abstract Background Children are commonly affected by respiratory tract infections. Based on clinical symptoms, laboratory evaluation, and imaging, the causative pathogen often cannot be delineated. Point‐of‐care‐testing systems that provide an opportunity for fast detection of common viruses and some bacteria can therefore influence treatment's options. We aimed to examine whether the Biofire® FilmArray® has an effect on antibiotic treatment, duration of antibiotic therapy, and length of hospital stay within a pediatric cohort. Methods We included children who were admitted to inpatient treatment with an acute respiratory tract infection from 02/2017 to 04/2018 using the FA respiratory pan…
Factors associated with 12 week case-fatality in Staphylococcus aureus bacteraemia: a prospective cohort study
2016
International audience; Staphylococcus aureus bacteraemia (SAB) is a frequent and deadly disease. Given the lack of a randomized trial, optimal first-line antibiotic treatment is still debated. Our aim was to identify prognostic factors in SAB patients and to analyse the impact of first-line antibiotics. The VIRSTA prospective cohort study was conducted in eight tertiary care centres in France. Consecutive incident adults in whom a blood culture drawn in participating centres grew S. aureus between April 2009 and October 2011 were prospectively followed for 12 weeks. Factors associated with 12-week case-fatality were identified by multivariate logistic regression. We enrolled 2091 patients …
Long‐term treatment with the oncolytic ECHO‐7 virus Rigvir of a melanoma stage IV M1c patient, a small cell lung cancer stage IIIA patient, and a his…
2016
Oncolytic virotherapy is a recent addition to cancer treatment. Here, we describe positive treatment outcomes in three patients using Rigvir virotherapy. One of the patients is diagnosed with melanoma stage IV M1c, one with small cell lung cancer stage IIIA, and one with histiocytic sarcoma stage IV. The diagnoses of all patients are verified by histology or cytology. All patients started Rigvir treatment within a few months after being diagnosed and are currently continuing Rigvir treatment. The degree of regression of the disease has been determined by computed tomography. Safety assessment of adverse events graded according to NCI CTCAE did not show any value above grade 1 during Rigvir(…
