High-Dose Cyproterone Acetate and Intracranial Meningioma: Impact of the Risk Minimisation Measures Implemented in France in 2018-2019.

Purpose: To measure the impact of national regulatory actions implemented in France in August 2018 and June 2019 to reduce the risk of meningioma associated with the use of cyproterone acetate (CPA).

Methods: Using the French National Healthcare database, we calculated the monthly number of CPA users among cisgender women, men and transgender women in 2010-2021, the monthly proportion of users with cerebral imaging screening, and the annual rate of meningioma surgery associated with CPA use. CPA discontinuations and switches were analysed.

Constitutional Factors and Irradiation as Risk Factors for Thymoma: A European Case-Control Study.

Little is known about the aetiology of thymoma. This study aims to identify medical risk factors for thymoma as a systematic approach to new hypotheses on the aetiology of this disease. A European multi-centre case-control study was conducted from 1995 to 1997, including incident cases aged 35-69 years with thymoma.

Usability, accuracy, and cost-effectiveness of a medical software for early pregnancies: a retrospective study.

Study Question: Can early pregnancies be accurately and cost-effectively diagnosed and managed using a new medical computerized tool?

Summary Answer: Compared to the standard clinical approach, retrospective implementation of the new medical software in a gynaecological emergency unit was correlated with more accurate diagnosis and more cost-effective management.

What Is Known Already: Early pregnancy complications are responsible for a large percentage of consultations, mostly in emergency units, with guidelines becoming complex and poorly known/misunderstood by practitioners.

Study Design, Size, Duration: A total of 780 gynaecological emergency consultations (446 patients), recorded between November 2018 and June 2019 in a tertiary university hospital, were retrospectively encoded in a new medical computerized tool.

Contribution of real-life studies in France during the COVID-19 pandemic and for the national pharmaco-epidemiological surveillance of COVID-19 vaccines.

During the COVID-19 pandemic, EPI-PHARE, a scientific group in pharmaco-epidemiology created by the French National Agency for the Safety of Medicines and Health Products (ANSM) and the French National Health Insurance (Cnam), has reoriented its work program to enlighten health authorities in this health crisis. By exploiting massive and complex data of the French Health Data System (SNDS) from the beginning of the first lockdown in France in March 2020, we were able to publish numerous results on the use, benefits and risks of medicines, on the risk factors of COVID-19 before and after vaccination, and on the benefits and risks of COVID-19 vaccines. Our results were widely taken into account by the French health authorities and allowed them to take informed decision in this pandemic situation in order to ensure the health of the population.

Impact of coronavirus disease 2019 on contraception use in France.

To limit the spread of the coronavirus disease 2019 (COVID 19), sanitary restrictions have been established since March 2020 in France. These restrictions and the waves of contamination may have had consequences on the use of health products in general, and on the use of contraceptives in particular. We aimed to assess the impact of COVID 19 pandemic from March 16th 2020 to April 30th 2021 in France on reimbursed contraceptives.

Defining measures of kidney function in observational studies using routine health care data: methodological and reporting considerations.

The availability of electronic health records and access to a large number of routine measurements of serum creatinine and urinary albumin enhance the possibilities for epidemiologic research in kidney disease. However, the frequency of health care use and laboratory testing is determined by health status and indication, imposing certain challenges when identifying patients with kidney injury or disease, when using markers of kidney function as covariates, or when evaluating kidney outcomes. Depending on the specific research question, this may influence the interpretation, generalizability, and/or validity of study results.

Immune disruptions and night shift work in hospital healthcare professionals: The intricate effects of social jet-lag and sleep debt.

Objectives: We aimed to examine the effects of circadian and sleep rhythm disruptions on immune biomarkers among hospital healthcare professionals working night shifts and rotating day shifts.

Methods: Hospital nurses working either as permanent night shifters (n=95) or as day shifters rotating between morning and afternoon shifts (n=96) kept a daily diary on their sleep and work schedules over a full working week. Blood samples were collected at the beginning and end of the last shift during the week, and participants were categorized into three groups based on work shift: morning shift (39 day shifters sampled at 7:00 and 14:00), afternoon shift (57 day shifters sampled at 14:00 and 21:00), and night shift (95 night shifters sampled at 21:00 and 7:00).

Optimization of Patient Management in the Gynecology Emergency Department Using Point-of-Care Beta hCG.

Background: Point-of-care testing (POCT) provides shorter turn-around times and, in many cases, potentially improves medical decision making. The AQT90 FLEX® benchtop immunoanalyzer (Radiometer Medical ApS, Copenhagen, Denmark) allows for the determination of beta-human chorionic gonadotropin (βhCG) in 18 min. The main aim of this study was to evaluate the impact of measuring βhCG using the AQT90 analyzer in the gynecology emergency department (ED) compared to the standard practice of using central laboratory blood testing on the patient length of stay (LOS).

Cesarean section rate changes after audit and feedback with the Ten Group Classification System in a French perinatal network: A retrospective pre-post study.

Introduction: The rise in the number of cesarean sections (CS) is a major health public problem which concerns nearly all countries. It is suggested that the Ten Group Classification System be adapted to a procedure of audit/feedback cycles, which could have an effect on CS practice. Therefore, we aimed to study changes in CS rates between maternity wards in a perinatal network after implementation of the Ten Group Classification System in an audit with feedback.

Occupation and prostate Cancer risk: results from the epidemiological study of prostate cancer (EPICAP).

Background: Although prostate cancer (PCa) is the most frequent male cancer in industrialized countries, little is known about its aetiology. The literature has suggested an influence of the environment, including occupational exposures, but results are inconsistent. In this context, we investigated PCa risk associated to employment among several occupations using data from EPICAP study.

A Rare Germline HOXB13 Variant Contributes to Risk of Prostate Cancer in Men of African Ancestry.

A rare African ancestry-specific germline deletion variant in HOXB13 (X285K, rs77179853) was recently reported in Martinican men with early-onset prostate cancer. Given the role of HOXB13 germline variation in prostate cancer, we investigated the association between HOXB13 X285K and prostate cancer risk in a large sample of 22 361 African ancestry men, including 11 688 prostate cancer cases. The risk allele was present only in men of West African ancestry, with an allele frequency in men that ranged from 0.

Impact of Coronavirus disease 2019 (COVID-19) on contraception use in 2020 and up until the end of April 2021 in France.

Objectives: To assess the impact of the COVID-19 pandemic on the use of reimbursed contraceptives in France after 15 months of the pandemic, according to age-group and updating previous data only pertaining to the first lockdown (2 months).

Study Design: We conducted a national register-based study by extracting all reimbursements of oral contraceptives (OC), emergency contraception (EC), intrauterine devices (IUD), and implants from the French National Health Insurance database (SNDS), which includes and covers 99.5% of the French population, in 2018, 2019, 2020 and from January 1, 2021 to April30, 2021.

Bayesian meta-analysis models for cross cancer genomic investigation of pleiotropic effects using group structure.

An increasing number of genome-wide association studies (GWAS) summary statistics is made available to the scientific community. Exploiting these results from multiple phenotypes would permit identification of novel pleiotropic associations. In addition, incorporating prior biological information in GWAS such as group structure information (gene or pathway) has shown some success in classical GWAS approaches.

Emotional Distress in the Relationship of Caregivers and Institutionalized Babies.

Institutionalization is an exceptional and temporary measure that occurs when there is a violation of rights; lasting until the family reintegration or, in the impossibility of this, the placement in a substitute family through adoption. Among the main reasons for institutionalization in Brazil are the financial difficulties, abandonment, domestic violence, drug addiction, homelessness of the responsible for the child, sexual abuse, and the loss of parents by death or imprisonment. Although children and adolescents have their rights assured when they are institutionalized, the care provided in these spaces does not include all their needs and demands, which may damage their affective-relational development.

Outdoor light at night at residences and breast cancer risk in Canada.

Experimental and epidemiologic studies suggest that light at night (LAN) exposure disrupts circadian rhythm, and this disruption may increase breast cancer risk. We investigated the potential association between residential outdoor LAN and breast cancer risk. A population-based case-control study was conducted in Vancouver, British Columbia and Kingston, Ontario, Canada with incident breast cancer cases, and controls frequency matched by age in the same region.

Appraising causal relationships of dietary, nutritional and physical-activity exposures with overall and aggressive prostate cancer: two-sample Mendelian-randomization study based on 79 148 prostate-cancer cases and 61 106 controls.

Background: Prostate cancer is the second most common male cancer worldwide, but there is substantial geographical variation, suggesting a potential role for modifiable risk factors in prostate carcinogenesis.

Methods: We identified previously reported prostate cancer risk factors from the World Cancer Research Fund (WCRF)'s systematic appraisal of the global evidence (2018). We assessed whether each identified risk factor was causally associated with risk of overall (79 148 cases and 61 106 controls) or aggressive (15 167 cases and 58 308 controls) prostate cancer using Mendelian randomization (MR) based on genome-wide association-study summary statistics from the PRACTICAL and GAME-ON/ELLIPSE consortia.

Diagnostic and Prognostic Performance of Blood Plasma Glycan Features in the Women Epidemiology Lung Cancer (WELCA) Study.

Lung cancer is the leading cause of cancer death in women living in the United States, which accounts for approximately the same percentage of cancer deaths in women as breast, ovary, and uterine cancers combined. Targeted blood plasma glycomics represents a promising source of noninvasive diagnostic and prognostic biomarkers for lung cancer. Here, 208 samples from lung cancer patients and 207 age-matched controls enrolled in the Women Epidemiology Lung Cancer (WELCA) study were analyzed by a bottom-up glycan "node" analysis approach.

Impact of the relative dose intensity on survival of patients with high-risk myelodysplastic syndromes treated with Azacitidine.

We performed a retrospective analysis of 93 myelodysplastic syndromes (MDS) patients with intermediate 2 or high-risk IPSS score to study the impact of Azacitidine (AZA) relative dose intensity (RDI) <80% on the overall survival (OS). There were 51.6% of patients who had full dose and 48.

Circadian genes and risk of prostate cancer: Findings from the EPICAP study.

Circadian rhythms regulate several physiological functions and genes controlling the circadian rhythm were found to regulate cell proliferation, cell cycle and apoptosis. Few studies have investigated the role of those circadian genes in prostate cancer occurrence. We aim to investigate the relationship between circadian genes polymorphisms and prostate cancer risk based on data from the EPICAP study, a population-based case-control study including 1,515 men (732 cases / 783 controls) with genotyped data.
