Comparative safety and effectiveness of oral anticoagulants in patients with non-valvular atrial fibrillation and high risk of gastrointestinal bleeding: A nationwide French cohort study.

Background: This observational study compared effectiveness and safety of direct oral anticoagulants (DOACs; apixaban, rivaroxaban, dabigatran) or vitamin K antagonists (VKAs) in patients with non-valvular atrial fibrillation (NVAF) at high risk for gastrointestinal bleeding (GIB).

Methods: Anticoagulant-naïve adults with NVAF with ≥1 GIB risk factor, initiating anticoagulant treatment January 2016-December 2019, and covered by the French national health data system were eligible. Outcomes included major bleeding (MB) and stroke/systemic embolism (SE).

Clinical burden and healthcare resource utilization associated with managing transfusion-dependent β-thalassemia in France.

Objective: To describe the clinical burden and healthcare resource utilization associated with managing transfusion-dependent β-thalassemia (TDT) in France.

Methods: We used the French National Health Data System (système national des données de santé) to identify eligible patients from January 1, 2012, to March 1, 2019. Inclusion criteria were a diagnosis of β-thalassemia, ≥8 red blood cell (RBC) transfusion episodes per year in ≥2 consecutive years following the diagnosis, and ≥1 year of follow-up data.

Reproductive characteristics, use of exogenous hormones and Parkinson disease in women from the E3N study.

Despite experimental studies suggesting a disease-modifying role of oestrogens, results from epidemiological studies on the relation of reproductive characteristics and hormonal exposures with Parkinson disease in women are conflicting. We used the data from the E3N cohort study including 98 068 women aged 40-65 years in 1990 followed until 2018. Parkinson disease was ascertained using a validation process based on drug claim databases and medical records.

Longitudinal associations of DNA methylation and sleep in children: a meta-analysis.

Background: Sleep is important for healthy functioning in children. Numerous genetic and environmental factors, from conception onwards, may influence this phenotype. Epigenetic mechanisms such as DNA methylation have been proposed to underlie variation in sleep or may be an early-life marker of sleep disturbances.

Female sex hormones and symptoms of obstructive sleep apnea in European women of a population-based cohort.

Background: The prevalence of obstructive sleep apnea is higher in women after menopause. This is suggested to be a result of an altered sex hormone balance but has so far not been confirmed in a population-based study.

Objective: To investigate whether serum concentration of estrogens and progesterone are associated with the prevalence of sleep apnea symptoms in middle-aged women of the general population.

Incidence of Parkinson's disease in French women from the E3N cohort study over 27Â years of follow-up.

Parkinson's disease (PD) is an uncommon disease with a long prodromal period and higher incidence in men than women. Large cohort studies of women with a long follow-up are needed. Within the E3N French cohort study (98,995 women, 40-65 years at baseline), we identified 3,584 participants who self-reported PD or used anti-parkinsonian drugs over 27 years (1992-2018).

Maternal Glycemic Dysregulation During Pregnancy and Neonatal Blood DNA Methylation: Meta-analyses of Epigenome-Wide Association Studies.

Objective: Maternal glycemic dysregulation during pregnancy increases the risk of adverse health outcomes in her offspring, a risk thought to be linearly related to maternal hyperglycemia. It is hypothesized that changes in offspring DNA methylation (DNAm) underline these associations.

Research Design And Methods: To address this hypothesis, we conducted fixed-effects meta-analyses of epigenome-wide association study (EWAS) results from eight birth cohorts investigating relationships between cord blood DNAm and fetal exposure to maternal glucose (Nmaximum = 3,503), insulin (Nmaximum = 2,062), and area under the curve of glucose (AUCgluc) following oral glucose tolerance tests (Nmaximum = 1,505).

DNA methylation changes associated with prenatal mercury exposure: A meta-analysis of prospective cohort studies from PACE consortium.

Mercury (Hg) is a ubiquitous heavy metal that originates from both natural and anthropogenic sources and is transformed in the environment to its most toxicant form, methylmercury (MeHg). Recent studies suggest that MeHg exposure can alter epigenetic modifications during embryogenesis. In this study, we examined associations between prenatal MeHg exposure and levels of cord blood DNA methylation (DNAm) by meta-analysis in up to seven independent studies (n = 1462) as well as persistence of those relationships in blood from 7 to 8 year-old children (n = 794).

Increased Risk of Parkinson's Disease in Women after Bilateral Oophorectomy.

Background: Results regarding the association between hormonal exposure and risk of Parkinson's disease (PD) are heterogeneous.

Objectives: To investigate the association of reproductive life characteristics with PD among postmenopausal women.

Methods: The PARTAGE case-control included 130 female cases and 255 age-matched female controls.

Spotlight on Cardiovascular Scoring Systems in Covid-19: Severity Correlations in Real-world Setting.

Objectives And Methods: the current understanding of the interplay between cardiovascular (CV) risk and Covid-19 is grossly inadequate. CV risk-prediction models are used to identify and treat high risk populations and to communicate risk effectively. These tools are unexplored in Covid-19.

Health impact assessment to predict the impact of tobacco price increases on COPD burden in Italy, England and Sweden.

Raising tobacco prices effectively reduces smoking, the main risk factor for chronic obstructive pulmonary disease (COPD). Using the Health Impact Assessment tool "DYNAMO-HIA", this study quantified the reduction in COPD burden that would occur in Italy, England and Sweden over 40 years if tobacco prices were increased by 5%, 10% and 20% over current local prices, with larger increases considered in secondary analyses. A dynamic Markov-based multi-state simulation modelling approach estimated the effect of changes in smoking prevalence states and probabilities of transitioning between smoking states on future smoking prevalence, COPD burden and life expectancy in each country.

Shared DNA methylation signatures in childhood allergy: The MeDALL study.

Background: Differential DNA methylation associated with allergy might provide novel insights into the shared or unique etiology of asthma, rhinitis, and eczema.

Objective: We sought to identify DNA methylation profiles associated with childhood allergy.

Methods: Within the European Mechanisms of the Development of Allergy (MeDALL) consortium, we performed an epigenome-wide association study of whole blood DNA methylation by using a cross-sectional design.

Foetal exposure to heavy metals and risk of atopic diseases in early childhood.

Background: Accumulating evidence suggests that in utero exposures can influence the development of the immune system and thus contribute to disease development. Studies investigating the association between prenatal exposures to heavy metals and atopic diseases, however, are scarce.

Methods: Children from the EDEN birth cohort were prospectively followed up using parental questionnaires with validated questions on asthma, allergic rhinitis, eczema, and food allergy symptoms.

Low serum DHEA-S is associated with impaired lung function in women.

Background: Emerging evidence suggests that androgens and estrogens have a role in respiratory health, but it is largely unknown whether levels of these hormones can affect lung function in adults from the general population. This study investigated whether serum dehydroepiandrosterone sulfate (DHEA-S), a key precursor of both androgens and estrogens in peripheral tissues, was related to lung function in adult women participating in the European Community Respiratory Health Survey (ECRHS).

Methods: Lung function and serum DHEA-S concentrations were measured in  = 2,045 and  = 1,725 women in 1999-2002 and in 2010-2013, respectively.

A Five-Step Vascular Ultrasound Examination in Heart Failure: The First Two Years of the "ABCDE" G-SIUMB Multicenter Study 2018-2022.

The aim of this study is the creation of a 5-step ultrasound examination to evaluate and monitor Heart Failure (HF) patients during hospitalization and follow-up. "ABCDE" is the acronym of an Italian multicentre study composed of a consecutive sample of HF patients admitted from the Emergency to the Internal Medicine/Geriatric Departments of several Italian hospitals. The "ABCDE" score includes the evaluations of A, the Ankle-brachial index (ABI), B, the B-lines, C, the Carotid intima media thickness (CIMT), D, the Diameter of the abdominal aorta and of the inferior cave vein and E, the echocardiographic assessment of the ejection fraction.

Incidence trends of airflow obstruction among European adults without asthma: a 20-year cohort study.

Investigating COPD trends may help healthcare providers to forecast future disease burden. We estimated sex- and smoking-specific incidence trends of pre-bronchodilator airflow obstruction (AO) among adults without asthma from 11 European countries within a 20-year follow-up (ECRHS and SAPALDIA cohorts). We also quantified the extent of misclassification in the definition based on pre-bronchodilator spirometry (using post-bronchodilator measurements from a subsample of subjects) and we used this information to estimate the incidence of post-bronchodilator AO (AO), which is the primary characteristic of COPD.
