The relative contributions of occupational and community sources of COVID-19 among health-care workers (HCWs) are still subject to debate. In a cohort study at a 2814-bed tertiary medical center (five hospitals) in the Paris area of France, we assessed the proportion of hospital-acquired cases among staff and identified risk factors. Between May 2020 and June 2021, HCWs were invited to complete a questionnaire on their COVID-19 risk factors. RT-PCR and serology test results were retrieved from the virology department. Mixed-effects logistic regression was used to account for clustering by hospital. The prevalence of COVID-19 was 15.6% (n = 213/1369 respondents) overall, 29.7% in the geriatric hospitals, and 56.8% of the infections were hospital-acquired. On multivariable analyses adjusted for COVID-19 incidence and contact in the community, a significantly higher risk was identified for staff providing patient care (especially nursing assistants), staff from radiology/functional assessment units and stretcher services, and staff working on wards with COVID-19 clusters among patients or HCWs. The likelihood of infection was greater in geriatric wards than in intensive care units. The presence of significant occupational risk factors after adjustment for community exposure is suggestive of a high in-hospital risk and emphasizes the need for stronger preventive measures—especially in geriatric settings.

Immunocompromised individuals generally fail to mount efficacious immune humoral responses following vaccination. The emergence of SARS-CoV-2 variants of concern has raised the question as to whether levels of anti-spike protein antibodies achieved after two or three doses of the vaccine efficiently protect against breakthrough infection in the context of immune suppression. We used a fluorescence-based neutralization assay to test the sensitivity of SARS-CoV-2 variants (ancestral variant, Beta, Delta, and Omicron BA.1) to the neutralizing response induced by vaccination in highly immunosuppressed allogeneic HSCT recipients, tested after two and three doses of the BNT162b2 vaccine. We show that neutralizing antibody responses to the Beta and Delta variants in most immunocompromised HSCT recipients increased after three vaccine doses up to values similar to those observed in twice-vaccinated healthy adults and were significantly lower against Omicron BA.1. Overall, neutralization titers correlated with the amount of anti-S-RBD antibodies measured by means of enzyme immunoassay, indicating that commercially available assays can be used to quantify the anti-S-RBD antibody response as a reliable surrogate marker of humoral immune protection in both immunocompetent and immunocompromised individuals. Our findings support the recommendation of additional early vaccine doses as a booster of humoral neutralizing activity against emerging variants, in HSCT immunocompromised patients. In the context of Omicron circulation, it further emphasizes the need for reinforcement of preventive measures including the administration of monoclonal antibodies in this high-risk population.

Emergency department (ED) overcrowding is an ongoing problem worldwide. Scoring systems are available for the detection of this problem. This study aims to combine a model that allows the detection and management of overcrowding. Therefore, it is crucial to implement a system that can reason model, rank ED resources and ED performance indicators based on environmental factors. Thus, we propose in this paper a new domain ontology (EDOMO) based on a new overcrowding estimation score (OES) to detect critical situations, specify the level of overcrowding and propose solutions to deal with these situations. Our approach is based on a real database created during more than four years from the Lille University Hospital Center (LUHC) in France. The resulting ontology is capable of modeling complete domain knowledge to enable semantic reasoning based on SWRL rules. The evaluation results show that the EDOMO is complete that can enhance the functioning of the ED. [ABSTRACT FROM AUTHOR]

The patient waiting time to be transferred for hospitalization is the time that the patient waits between the decision to hospitalize and the actual admission to an inpatient hospital bed. One of the difficulties encountered in qualifying waiting time for inpatient bed is the inability of hospital information systems to measure it. Hospitals in France have a specialized bed allocation team. This team must manage the bed allocation problem between different hospital departments using phone communication to assign patients to the adapted service. This kind of communication represents a lengthy additional workload in which effectiveness is uncertain. This paper presents a new approach to automate bed management in downstream service. For that, we have implemented algorithms based on artificial intelligent integrated in an inpatient web platform using IoT-Beacons, which is implemented to improve and facilitate the exchange of availability information of downstream beds within the Lille university hospital center (LUHC).

This paper establishes some stylized facts of the long-run relationship between growth and labor shares using historical data for the USA (1898–2010), the United Kingdom (1856–2010), and France (1896–2010). Performing individual country time–frequency analysis, we demonstrate the existence of long-term cycles in labor share of 30–50 years explaining a major part of the variance in the data. Further, the impact of labor share on growth changes sign with the frequency considered from negative at high frequencies to positive at low frequencies. Finally, the positive coefficient associated with the labor share at low frequencies increases over time. [ABSTRACT FROM AUTHOR]

Aim: Enhanced recovery programmes (ERPs) involve early postoperative oral feeding. The aim of this study was to test the hypothesis that intolerance to early feeding was associated with a complicated postoperative course. Method: A retrospective cohort analysis of the prospective multicentre database developed by the Francophone Group for Enhanced Recovery after Surgery (GRACE) was undertaken. Seventy‐one centres in Belgium, France and Switzerland participated in the study. All patients were encouraged to eat within 24 h after surgery. Patients were separated into two groups according to whether early feeding was well tolerated (WT) or poorly tolerated (PT). The primary outcome measure was overall postoperative complications. Secondary outcome measures were unplanned reoperation, early mobilization rate and duration of postoperative hospital stay. Results: Among the cohort of 3034 patients, early feeding was WT in 2614 patients (WT group) and PT in 420 patients (PT group). There were significantly more postoperative complications in the PT group than in the WT group (52.1% vs 17.0%, respectively; P = 0.001), namely more unplanned reoperations, less early mobilization and longer postoperative hospital stay. Multivariate analyses confirmed that PT early feeding was the main and dominant independent factor for postoperative complications [OR 4.47 (95% CI3.49–5.72); P < 0.001], more unplanned reoperations and longer hospital stay. Conclusions: This study demonstrates a close relationship between intolerance to early feeding and a complicated postoperative course. Whenever this simple very early red flag is observed, discharge should not be planned until postoperative complications have been ruled out. [ABSTRACT FROM AUTHOR]

Well-known and suitable instruments for surgical audit are the POSSUM and P-POSSUM scoring systems. But these scores have not been well validated across the countries. The objective of the present study was to assess the predictive value of scores for colorectal surgery in France. Patients operated on for colorectal malignant or diverticular diseases, whether electively or on emergency basis, within a 4-month period were included in a prospective multicenter study conducted by the French Association for Surgery (Association Française de Chirurgie, AFC). The main outcome measure was postoperative in-hospital mortality. Independent factors leading to death were assessed by multivariate logistic regression analysis (AFC-index). The ratio of expected versus observed deaths was calculated, and the predictive value of the POSSUM and P-POSSUM scores were analyzed by the receiver operating characteristic (ROC) curve. A total of 1426 patients were included. The in-hospital death rate was 3.4%. Four independent preoperative factors (AFC-index) have been found: emergency surgery, loss of more than 10% of weight, neurological disease history, and age > 70 years. POSSUM had a poor predictive value; it overestimated postoperative death in all cases. P-POSSUM had a good predictive value, except for elective surgery, where it overestimated postoperative death twofold. The predictive value of the AFC-index was also good. It had the same sensitivity and specificity as the P-POSSUM. POSSUM has not been validated in France in the field of colorectal surgery. P-POSSUM was as predictive as the AFC-index which is a simpler instrument based on four clinical parameters (without any mathematical formulas). [ABSTRACT FROM AUTHOR]

AbstractA precise assessment of the epidemiological extent of equine Lyme disease is not well established in metropolitan France, French Guiana, and Africa (Chad, Djibouti, Ivory Coast, Gabon, and Democratic Republic of Congo). Blood samples were obtained from 570 horses. The samples were tested for Borrelia burgdorferiinfection by a commercial ELISA Dot-Blot method (SNAP®4 Dx; IDEXX S. Laboratory). Lyme disease antibodies were only detected in metropolitan France, specifically in the eastern and center-western regions (48% and 31%). The geographical distribution of the disease follows the distribution of the vector. [ABSTRACT FROM AUTHOR]

Abstract To the best of our knowledge, there is no econometric study on the causal relationship between renewable or fossil energies and terrorism, nor on terrorism in France. This paper tries to fill this gap and considers other variables as economic growth and trade openness. The autoregressive distributed lag approach and Granger causality are used for annual data on France covering the period 1980–2015. The Wald test confirms the existence of long-run relationships between the considered variables. Granger causality reveals long-run bidirectional causalities between all the variables. Interestingly, in the short-run, there are unidirectional causalities running from renewable energy to terrorism, and from terrorism to trade openness, and there is bidirectional causality between terrorism and economic growth. Long-run parameter estimates show that more renewable energy consumption and more trade increase both terrorism and economic growth. However, economic growth reduces terrorism in the long-run and appears as a powerful tool to combat terrorism in France. In addition, France is recommended to continue encouraging the use of renewable energies, and at the same time, to make more diplomatic efforts to resolve political and military conflicts in the world, and particularly in the Middle East. Highlights • There is long-run bidirectional causality between renewable energy and terrorism. • There is long-run bidirectional causality between fossil energy and terrorism. • There is short-run unidirectional causality running from renewable energy to terrorism. • In the long run, renewables increase terrorism and economic growth. • In the long run, economic growth reduces terrorism and increases renewable energy.

Background: Surgical skin preparation is performed according to peri-operative antisepsis protocols. These protocols are based on clinical practice recommendations and may vary from institution to institution. Materials and Methods: The objective of the survey, conducted among 481 surgeons and 98 scrub nurses of five specialties (cardiac, gastrointestinal, obstetrics and gynecology, orthopedics, and urology) in France was to take stock of practices to identify the protocols used for surgical skin preparation, such as measures relating to pre-operative showering, hair removal, or antisepsis of the operating area. Results: Two pre-operative showers with hair washing are usually carried out on the same day as the procedure (63%) or the day before the procedure (37%), mostly with an antiseptic (54%, soap 42%). Hair removal and cleaning/scrubbing are most often performed before the procedure (in 62% and 79% of cases, respectively). Alcoholic povidone-iodine is the most widely used antiseptic, and 81% of surgeons opt for complete spontaneous drying. Before making the incision, 41% of surgeons use drapes and 62% opt for an operative field irrigation technique during or at the end of the procedure. Surgeons mainly use running subcuticular sutures or running locking sutures (39%) and 93% use dressings. Thirty-six percent of the surgeons surveyed said the antisepsis protocols described were likely to be adapted. Conclusions: The results showed that international and French recommendations are mostly well followed by surgeons and scrub nurses in France. However, some differences are observed between surgical specialties, depending on the clinical situations encountered and the type of practice. [ABSTRACT FROM AUTHOR]

Abstract: Monitoring cytomegalovirus circulating viral load is an important parameter of the follow-up in immunocompromised patients. It can be measured either by DNAemia or by pp65 antigenemia. The French national reference center for cytomegaloviruses organized an investigation of practice in 37 teacher hospital virology laboratories to assess the situation in France in 2010. Methods: A questionnaire was sent to collect following information: method used in routine for monitoring of circulating viral load of CMV, assay used, sample matrix and extraction method. Results: Thirty-six over thirty-seven laboratories filled the questionnaire. Among these, 67% used the quantitative PCR in routine, 11% antigenemia and 22% antigenemia or quantitative PCR; 87% of the laboratories use whole blood for quantitative PCR, whereas 10% and 3% use plasma and leukocytes respectively. Among the laboratories using DNAemia, 100% used real-time PCR assays, 91% use an automated extraction and 9% a manual extraction. Conclusion: Thus in France, measurement of DNAemia by real-time PCR is a tool, which gradually replaces the antigenemia for the monitoring of cytomegalovirus infection among immunocompromised patients. The very great diversity of the methods used justifies the installation of a national quality control on total blood, matrix used by 87% of the laboratories. [Copyright &y& Elsevier]
