Can we consider immediate complications after thyroidectomy as a quality metric of operation?

Jean-Christophe Lifante, Cécile Payet, Fabrice Ménégaux, Frédéric Sebag, more

Surgery > 2017 > 161 > 1 > 156-165

Permanent recurrent laryngeal nerve palsy and hypoparathyroidism are 2 major complications after thyroid operation. Assuming that the rate of immediate complications can predict the permanent complication rate, some authors consider these complications as a valid metric for assessing the performance of individual surgeons. This study aimed to determine the correlation between rates of immediate and...

Philippe Vanhems, Nicolas Voirin, Thomas Bénet, Sylvain Roche, more

AJIC: American Journal of Infection Control > 2014 > 42 > 12 > 1325-1327

The risk of nosocomial influenza-like illness (noso-ILI) compared with that of community-acquired ILI was calculated during 3 influenza seasons (2004-2007) at a 1100-bed university hospital with a total of 21,519 hospitalized patients. Outbreaks of noso-ILI occurred in each season, although a protective effect against noso-ILI was also identified for other wards.

Florent Valour, Laurent Cotte, Nicolas Voirin, Matthieu Godinot, more

Vaccine > 2014 > 32 > 35 > 4558-4564

Several vaccines are recommended in HIV-infected patients due to an increased risk of vaccine-preventable infections, severe forms of the disease, or shared transmission routes. Few data are available regarding vaccination coverage and its determinants in this population.A cross-sectional study was performed in HIV-infected patients included in a hospital-based cohort in 2011. Vaccination coverage...

Influenza and Other Respiratory Viruses > 7 > 3 > 364 - 366

Surveillance of incident influenza‐like illness (ILI) was implemented in two children and adult medical emergency departments during the influenza A (H1/N1) pandemic to assess correlations in the daily number of ILI‐related emergency room visits (ERV) between these departments. A total of 7165 ILIs in children and 610 ILIs in adults were observed. We noticed a high linear correlation between the number...

Influenza vaccination coverage among patients and healthcare workers in a university hospital during the 2006–2007 influenza season

Caroline Landelle, Philippe Vanhems, Mitra Saadatian-Elahi, Nicolas Voirin

Vaccine > 2012 > 31 > 1 > 23-26

Despite years of public health effort to increase vaccine uptake among populations recommended for influenza vaccination, immunization rates remain low among patients and healthcare workers (HCWs). The objective of this study was to report on influenza vaccination coverage of patients and HCWs for the same time period in 4 wards of a university hospital. A prospective cross-sectional study was conducted...

The aim of this study was to estimate influenza vaccine effectiveness (IVE) against laboratory-confirmed influenza among hospitalized patients. A case–control investigation was based on the prospective surveillance of influenza-like illness (ILI) during five flu seasons. We compared influenza-positive cases and influenza-negative controls. Unadjusted overall IVE was 62% (95% confidence interval 24%...

Philippe Vanhems, Thomas Bénet, Nicolas Voirin, Jean-Marie Januel, more

BMC Infectious Diseases > 2011 > 11 > 1 > 1-6

Background The incidence of ventilator-associated pneumonia (VAP) within the first 48 hours of intensive care unit (ICU) stay has been poorly investigated. The objective was to estimate early-onset VAP occurrence in ICUs within 48 hours after admission. Methods We analyzed data from prospective surveillance between 01/01/2001 and 31/12/2009 in 11 ICUs of Lyon hospitals (France). The inclusion criteria...

Low monocyte human leukocyte antigen-DR is independently associated with nosocomial infections after septic shock

Caroline Landelle, Alain Lepape, Nicolas Voirin, Eve Tognet, more

Intensive Care Medicine > 2010 > 36 > 11 > 1859-1866

Purpose Sepsis-induced immunosuppression is postulated to contribute to a heightened risk of nosocomial infection (NI). This prospective, single-center, observational study was conducted to assess whether low monocyte human leukocyte antigen-DR expression (mHLA-DR), proposed as a global biomarker of sepsis immunosuppression, was associated with an increased incidence of NI after septic shock. Methods...

Contribution of cell culture, RNA extraction, and reverse transcription to the measurement error in quantitative reverse transcription polymerase chain reaction-based gene expression quantification

Jean-Damien Combes, Gaël Grelier, Matthieu Laversanne, Nicolas Voirin, more

Analytical Biochemistry > 2009 > 393 > 1 > 29-35

Quantitative polymerase chain reaction (qPCR) instruments are known to be reliable. However, many authors have underlined the poor reliability of the procedures that precede the measurement of gene expression —cell culture, RNA extraction, and reverse transcription. Here we quantified the measurement errors due to each step and estimated the correction that would accrue from replicating any of those...

Caroline Guignant, Nicolas Voirin, Fabienne Venet, Françoise Poitevin, more

Intensive Care Medicine > 2009 > 35 > 11 > 1859-1867

Purpose Improvements in survival after septic shock will most likely rely on our capacity to manage individualized therapies based on the measurement of rapidly accessible biomarkers. As the early phase of septic shock is dominated by severe alterations of the cardiovascular system, the predictive value for mortality of pro-vasopressin (pro-AVP) and pro-adrenomedullin (pro-ADM), two vasoactive pro-hormones,...

Breast Cancer Research and Treatment > 2007 > 101 > 2 > 233-245

Purpose The debate concerning poorer survival for patients with breast cancer (BC) carrying a BRCA1 germline mutation is unresolved, and requires additional data from population-based studies. Patients and methods We followed 232 women with invasive BC under age 46, ascertained prospectively through a French population-based BC registry and tested for BRCA1/2 mutations (median follow-up: 82 months)...
