Hospitalisation avec ou pour COVID-19 : quel indicateur de surveillance choisir ?

INTRODUCTION: In the SARS-CoV-2 epidemic, the monitoring of epidemiological surveillance indicators is a central issue. OBJECTIVE: We were able to describe the monitoring of the epidemic of hospitalized patients in the department of Alpes-Maritimes from three data sources: 1) Santé Publique France (SPF) via the SI-VIC software, 2) the Regional Health Agency (ARS Paca) with conventional hospitalization or department critical care data taken from SI-VIC, adjusting them to those of the Health Establishments (ES), 3) The ES of Alpes-Maritimes associated with the ARS of Alpes-Maritimes and the Department of Public Health (DSP) of the CHU, with the collection of patients hospitalized in the conventional sector or in critical/intensive care in the dedicated COVID-19 beds. The aim of this study was to verify the consistency of these three information systems. RESULTS: We observed disparities between the number of cases of hospitalization of SPF and the data from ES/ARS/DSP. We did not observe any differences in patients hospitized in intensive care/critical care units. The Scientific Council uses SPF data on the number of hospitalizations or intensive/critical beds to justify its recommendations.However, SPF data from SI-VIC have associated patients hospitalized for COVID and patients who tested positive for PCR, but whose reason for hospitalization is not related to SARS-CoV2 infection (formerly infected or asymptomatic patients). CONCLUSIONS: We believe that hospital surveillance indicators should only take into account the number of patients in conventional hospitalization or resuscitation for a COVID-19 infection.

Anthropometric Risk Factors for Differentiated Thyroid Cancer in Young Men and Women From Eastern France: A Case-Control Study.

The incidence of thyroid cancer has risen over the past decade, along with a rise in obesity. We studied the role of anthropometric risk factors for differentiated thyroid cancer at the time of diagnosis and at age 20 years in a case-control study conducted in eastern France between 2005 and 2010. The study included 761 adults diagnosed with differentiated thyroid cancer before 35 years of age between 2002 and 2006. They were matched with 825 controls from the general population. Odds ratios were calculated using conditional logistic regression models and were reported for all participants, those with papillary cancer only, and women only. The risk of thyroid cancer was higher for participants with a high body surface area (BSA), great height, or excess weight and for women with a high body fat percentage. Conversely, no significant association was found between body mass index and the risk of thyroid cancer. In the present study, we provide further evidence of the role of BSA and excess weight in the risk of thyroid cancer. These epidemiologic observations should be confirmed by further exploration of the biological mechanisms responsible for the associations of obesity and BSA with thyroid cancer.

Obstetric management does not influence vertical transmission of HCV infection: results of the ALHICE group study.

OBJECTIVE: To investigate the impact of variation in obstetric practice during labor and childbirth upon the rate of neonatal transmission of HCV. METHODS: Pregnant mothers were included in this prospective study from six hospitals in Southern France on the basis of positive HCV serology. Data recorded for the study included maternal factors, delivery details and laboratory data concerning mother and child. Pediatric follow-up was documented for a minimum of 1 year and for up to 2 years for children with circulating HCV RNA. RESULTS: Two hundred and fourteen mother-child pairs were investigated. HIV/HCV co-infected mothers had a rate of HCV transmission significantly higher (11%) than that observed for mono-infected mothers (3.8%) (odds ratio=3.08 [95% CI:0.95 to 9.99] p=0.05). When the HCV viral load was greater than or equal to 6 log copies/ml, the transmission rate was 14.3% [95% CI:5.4-28.5], this representing a risk of transmission four times higher than for women with a lower viral load (OR=4 [95% CI:1.3-12.4]). Among co-infected mothers, the risk of transmission was significantly increased even when the load was less than 6 log copies/ml (p=0.006). Risk factors were identified related to labor (duration and induction type); the birth process (rupture of the amniotic sac, complete opening of the sac, appearance of the amniotic fluid); fetal characteristics (prematurity) and obstetric maneuvers (instrumental extractions, spontaneous or induced perineal trauma) and none of these factors were associated with an increased rate of HCV maternal-fetal transmission. CONCLUSIONS: HCV infection does not appear to be a legitimate indication for modifying obstetric practices with regards to type of induction, monitoring of labor, route of delivery, fetal and perineal obstetric maneuvers or care of the newborn in the delivery room.

Investigating the completeness of a histopathological cancer registry: estimation by capture-recapture analysis in a French geographical unit Alpes-Maritimes, 2008.

INTRODUCTION: Cancer population studies require reliable and complete baseline data, which should theoretically be available by collecting histopathology records. The completeness of such a collection was evaluated using capture-recapture analysis based on three data sources concerning breast and colorectal cancers over an identical period and within the same geographical area. METHOD: The total number of breast and colon cancer cases was estimated using capture-recapture analysis based on the number of cases which were common or not between sources recording screened, diagnosed and treated cancers in the French Alpes Maritimes district. RESULT: The estimated total number of new cases of breast cancer diagnosed among Alpes Maritimes residents women aged 50-75 was 791 (95% CI: 784-797) in 2008. Of these 791 cases, 729 were identified through histopathology records, thus amounting to 92.2% completeness (95% CI: 91.5-93.0%). The total estimated number of new cases of colorectal cancer diagnosed among Alpes Maritimes residents aged 50-75 was 527 (95% CI: 517-536). Of these 527 cases, 481 were identified through histopathology records, thus amounting to 91.3% completeness (95% CI: 89.7-93.0%). CONCLUSION: The estimated completeness of cancer records collected from histopathology laboratories was higher than 90% for new cases of breast and colorectal cancer within the age range concerned by the screening programme. A verified and validated histopathology data collection may be useful for cancer population studies.

Fatigue in irritable bowel syndrome: characterization and putative role of leptin.

OBJECTIVES: Fatigue has received little attention in the irritable bowel syndrome. Emerging evidence exists that leptin may be involved in the pathogenesis of fatigue in several conditions. We aimed to evaluate the occurrence of fatigue and its characteristics in irritable bowel syndrome and to analyze the relationship between fatigue and leptin. METHODS: We enrolled 51 consecutive irritable bowel syndrome patients and 22 healthy controls without fatigue. None of them were depressed. The Fatigue Impact Scale was used to evaluate fatigue. RESULTS: In all, 62.7% of irritable bowel syndrome patients verbally expressed fatigue and rated more than 4 on the visual analog scale. The total score of fatigue was significantly higher in irritable bowel syndrome than in controls. In irritable bowel syndrome patients, but not in controls, a significant association was found between the total score of fatigue and leptin and this association was more pronounced in 32 irritable bowel syndrome patients who verbally expressed fatigue (r=0.60; P=0.0003). In irritable bowel syndrome, leptin correlated with fatigue independently from age, sex, fat mass and body mass index. CONCLUSIONS: Our study shows that fatigue occurs in 62.7% of irritable bowel syndrome patients when systematically asked for. Fatigue influences all three domains of the Fatigue Impact Scale in irritable bowel syndrome, the most being the physical and the psychosocial domains. Fatigue is associated with circulating leptin levels independently from age, sex, fat mass and body mass index in irritable bowel syndrome. The metabolic sequence involved in the occurrence of fatigue remains to be determined.
