Hospital-acquired infections worldwide in relation to Gross Domestic Product
Hospital-acquired infections (HAI) are a major public health problem worldwide. The World Health Organization estimates that 7% of patients could be affected by at least one HAI in high income countries (HICs), and 15% in low- and middle-income countries (LMICs).We hypothesized that countries with higher Groos Domestic Product (GDP) would have lower HAI prevalence rates, reflecting better investment in infection prevention and control programs.We…
Clustering and visualisation of the Gabriel network expertise in the field of infectious diseases
INTRODUCTION: The Global Approach to Biology Research, Infectious diseases and Epidemics in Low-income countries (GABRIEL) network is an international scientific network of 21 centres coordinated by the Merieux Foundation (Lyon, France). Mapping and characterising the similarities and differences in expertise and activities across four major infectious diseases (tuberculosis, antimicrobial-resistant infections, acute respiratory infections and em…
Development and validation of a novel clinical risk score to predict hypoxaemia in children with pneumonia using the WHO PREPARE dataset
BACKGROUND: Hypoxaemia predicts mortality at all levels of care, and appropriate management can reduce preventable deaths. However, pulse oximetry and oxygen therapy remain inaccessible in many primary care health facilities. We aimed to develop and validate a simple risk score comprising commonly evaluated clinical features to predict hypoxaemia in 2-59-month-old children with pneumonia. METHODS: Data from seven studies conducted in five countri…
Urban environment and RSV
Substantial neighbourhood-level differences in RSV SARI incidence exist in a large European metropolis. These differences are associated with the urban environment such as particulate pollution. The use of spectral indices shows promise in identifying vulnerable populations within cities to guide public health measures and to integrate public health and urban planning
Seroprevalence of seven arboviruses of public health importance in sub-Saharan Africa
Factors Associated with Long Covid-19 in a French Multicentric Prospective Cohort Study
(1) Background: A substantial proportion of COVID-19 patients continue to experience long-lasting effects that hamper their quality of life. The objectives of this study were (1) to report the prevalence of persistent clinical symptoms 6-12 months after the onset of COVID-19 and (2) to identify potential factors at admission associated with the occurrence of long COVID. (2) Methods: A prospective study was conducted among COVID-19 adult patients,…
Factors associated with the nutritional status of children under 5 years of age in Guinea between 2005 and 2018
Objective: To determine the factors associated with the nutritional status of children under 5 years of age in Guinea between 2005 and 2018. Design: Data from the 2005, 2012 and 2018 Guinea Demographic and Health Surveys (DHS) were used for this study. Three anthropometric indicators (stunting, underweight and wasting) were assessed according to the 2006 WHO Child Growth Standards and analysed according to the year, the characteristics of the hou…
Derivation and validation of a novel risk assessment tool to identify children aged 2–59 months at risk of hospitalised pneumonia-related mortality in 20 countries
INTRODUCTION: Existing risk assessment tools to identify children at risk of hospitalised pneumonia-related mortality have shown suboptimal discriminatory value during external validation. Our objective was to derive and validate a novel risk assessment tool to identify children aged 2-59 months at risk of hospitalised pneumonia-related mortality across various settings. METHODS: We used primary, baseline, patient-level data from 11 studies, incl…
Assembling a global database of child pneumonia studies to inform WHO pneumonia management algorithm
Background: The existing World Health Organization (WHO) pneumonia case management guidelines rely on clinical symptoms and signs for identifying, classifying, and treating pneumonia in children up to 5 years old. We aimed to collate an individual patient-level data set from large, high-quality pre-existing studies on pneumonia in children to identify a set of signs and symptoms with greater validity in the diagnosis, prognosis, and possible trea…
Bacterial Cross-Transmission between Inanimate Surfaces and Patients in Intensive Care Units under Real-World Conditions
Background/Objectives : Contaminated surfaces play an important role in the nosocomial infection of patients in intensive care units (ICUs). This study, conducted in two ICUs at Edouard Herriot Hospital (Lyon, France), aimed to describe rooms' microbial ecology and explore the potential link between environmental contamination and patients' colonization and/or infection. Methods: Environmental samples were realized once monthly from January 2020 …
National influenza surveillance systems in five European countries
This new framework can be used to compare influenza surveillance systems qualitatively between countries to allow the identification of structural differences as well as to evaluate adherence to WHO guidance. The framework may be adapted for other infectious respiratory diseases

External validation of the Risc, Risc-Malawi, and PERCH clinical prediction rules to identify risk of death in children hospitalized with pneumonia
BACKGROUND: Existing scores to identify children at risk of hospitalized pneumonia-related mortality lack broad external validation. Our objective was to externally validate three such risk scores. METHODS: We applied the Respiratory Index of Severity in Children (RISC) for HIV-negative children, the RISC-Malawi, and the Pneumonia Etiology Research for Child Health (PERCH) scores to hospitalized children in the Pneumonia REsearch Partnerships to …
Factors Associated with Clostridioides (Clostridium) Difficile Infection and Colonization
Clostridioides (Clostridium) difficile can be isolated from stool in 3% of healthy adults and in at least 10% of asymptomatic hospitalized patients. C. difficile , the most common cause of hospital-acquired infectious diarrhea in the developed world, has re-emerged in recent years with increasing incidence and severity. In an effort to reduce the spread of the pathogen, published recommendations suggest isolation and contact precautions for patie…
Comparison of influenza surveillance systems in Australia, China, Malaysia and expert recommendations for influenza control
Influenza monitoring in Australia, China, and Malaysia could benefit from the expansion of existing surveillance sentinel schemes, the broadened use of laboratory confirmation and the introduction of excess-mortality modelling. The results from the evaluation can be used as a basis to support expert recommendations and to enhance influenza surveillance capabilities
Epidemiology and timing of seasonal influenza epidemics in the Asia-Pacific region, 2010–2017
Influenza virus circulation varied considerably across the Asia-Pacific region with an unusually high burden of influenza B. The recommended timing for vaccination was appropriate in most countries, except for several countries with unclear seasonality, mainly located in the inter-tropical area
Prevalence and factors associated with overweight and obesity among children from primary schools in urban areas of Lomé, Togo
Objective Overweight and obesity in childhood are serious public health issues, both in developing and developed countries. The present study aimed to ascertain overweight and obesity prevalence rates among Togolese schoolchildren in Lomé, Togo, and their correlation with physical activity, socio-economic conditions and eating habits. Design Cross-sectional survey conducted in December 2015. Overweight and obesity were defined using age- and sex-…
First presentation for care of HIV-infected patients with low CD4 cell count in Lyon, France
To identify the risk factors associated with presentation for care with CD4 cell count ≤ 200 cells/mm(3) and death in HIV-infected patients in Lyon, France. Data were analyzed on participants from mid-1992 to December 2006 in the Lyon section of the French Hospital Database on HIV Infection. Patients were stratified into two categories according to CD4 cell count at first presentation for care in University of Lyon hospitals: Group 1 (Gr1) patien…
French women’s knowledge of and attitudes towards cervical cancer prevention and the acceptability of HPV vaccination among those with 14 – 18 year old daughters
Few mothers are opposed to HPV vaccination. Factors associated with acceptability were knowledge about the vaccine, acceptance of other vaccines and, unexpectedly, lack of knowledge about the recommended frequency of Pap testing. On multivariate analysis, compliance with recommendations for Pap test screening and socioeconomic factors had no effect on views about HPV vaccination. Given that concern about possible side effects is the major barrier…
Evaluation of adult dTPaP vaccination coverage in France
The main thrust of this study was to compare reported and confirmed data. A significant percentage of people wrongly believed that they were up to date with their vaccination
P1-463 HPV vaccination
Objectives To examine knowledge about HPV vaccination and behaviour towards STD among 14–23-year-old (yo) girls and determine the correlation with HPV vaccination status. Methods From 11/2008 to 04/2009, 316 girls were recruited by general practitioners in a cross-sectional study and filled a self-administered questionnaire. Twenty-eight were interviewed by a sociologist. Results Of the 316 girls, HPV vaccination was reported by 135 (42.7%). Pare…
SP3-67 Kaposi sarcoma incidence in Uganda and Zimbabwe, before and during HIV/Aids epidemic
