Objective: Anorexia nervosa (AN) is an eating disorder characterised by voluntary dietary restriction leading to severe undernutrition. Hypoglycaemia is mostly described through severe case reports and is always evaluated by fasting or post-meal blood glucose, showing nothing about hypoglycaemia's length or duration. The interest of continuous interstitial glucose monitoring (CGM), largely used in diabetes mellitus, has never been evaluated in AN patients.

Background: The rate of positive tests using fecal immunochemical test (FIT) does not decrease with subsequent campaigns, but the positive predictive value of advanced neoplasia significantly decreases in subsequent campaign after a first negative test. A relationship between the fecal hemoglobin concentration (Fhb) and the opportunity to detect a colorectal cancer in subsequent campaign has been shown.

Aim: To predict the severity of colorectal lesions based on Fhb measured during previous colorectal cancer screening campaign.

Meta-analyses of randomized controlled trials that started from 1963 to 1991 reported a decrease of breast cancer mortality, associated with mammography screening. However, the effectiveness of population-based screening programs conducted currently might have changed due to the higher effectiveness of treatments for late-stage cancers and the better diagnostic performance of mammography. The main objective of this study was to predict the reduction of breast cancer mortality associated with mammography screening in the current French setting.

Introduction: The objective of our study was to describe and analyse the Post-Colonoscopy Colorectal Cancers (PCCRCs) and endoscopist performance-related risk factors in the Isère regional screening programme.

Method: This was a population-based retrospective cohort study between 2002-2013, where Post-Colonoscopy Colorectal Cancers (PCCRCs) were defined as colorectal adenocarcinoma diagnosed between six and sixty months post-colonoscopy following a positive gFOBT. We analysed the endoscopist performance-related risk factors of the 62 gastroenterologists who had carried out at least 30 colonoscopies during this period.

Importance: Professional use of pesticides is a risk factor for non-Hodgkin lymphoma. The main biological mechanisms of pesticides and chemotherapy are genotoxicity and reactive oxygen species generation. Cellular adaptation among patients exposed to low doses of genotoxic and oxidative compounds might hinder chemotherapy efficiency in patients with lymphoma.

Objectives: The magnitude of overdiagnosis of breast cancer associated with mammography screening remains controversial because of methodological issues. The objective of this study was to quantify overdiagnosis and overtreatment associated with a population-based screening programme, taking into account lead time and uncertainty concerning baseline incidence of breast cancers.

Material And Methods: A simulation model was developed to replicate incidence and detection rates of breast cancer observed in the Isère Département, France.

Background: In France, breast cancer screening programme, free of charge for women aged 50-74 years old, coexists with an opportunistic screening and leads to reduction in attendance in the programme. Here, we reported participation in organized and/or opportunistic screening in thirteen French departments.

Population And Methods: We analyzed screening data (organized and/or opportunistic) of 622,382 women aged 51-74 years old invited to perform an organized mammography screening session from 2010 to 2011 in the thirteen French departments.

Background: Measuring adenoma detection is a priority in the quality improvement process for colonoscopy. Our aim was (1) to determine the most appropriate quality indicators to assess the neoplasia yield of colonoscopy and (2) to establish benchmark rates for the French colorectal cancer screening programme.

Methods: Retrospective study of all colonoscopies performed in average-risk asymptomatic people aged 50-74 years after a positive guaiac faecal occult blood test in eight administrative areas of the French population-based programme.

Background: The main objective of this study was to estimate the sensitivity of a colorectal cancer-screening program based on a guaiac fecal occult blood (FOB) test. The secondary objective was to determine whether the sensitivity varied by sex and if the difference between males and females could be explained by differences in age group at the time of the test, round of screening, how the test was provided to the participant, tumor location, and the presence of theoretical screening program exclusion criteria.

Methods: For the 2002-2006 period, we retrospectively analyzed data from the organized colorectal screening program in Isère, France, which was designed for asymptomatic individuals aged 50-74.

Introduction: This study aimed at modelling the effect of organized breast cancer screening on mortality in France. It combined results from a Markov model for breast cancer progression, to predict number of cases by node status, and from relative survival analyses, to predict deaths. The method estimated the relative risk of mortality at 8 years, in women aged 50-69, between a population screened every two years and a reference population.

Background: A pilot program of organized screening for colorectal cancers was conducted in Isère, an administrative district in France. A fecal occult blood test (Hemoccult II(®)) was proposed for all individuals aged greater than 50 years (women since 1991 and men since 2002), followed by colonoscopy for those testing positive. A prospective study was carried out from May to July in 2004 and compared with a similar study conducted in 1996.

Purpose: The screening program guidelines specify that the call back rate of women for additional imaging (positive mammogram) should not exceed 7% at initial screening, and 5% at subsequent screening. Materials and methods. Results in the Isere region (12%) have prompted a review of the correlation between the call back rate and indicators of quality (detection rate, sensitivity, specificity, positive predictive value) for the radiologists providing interpretations during that time period.
