Development and validation of a model to identify polycystic ovary syndrome in the French national administrative health database.

Background: We aimed to develop and validate an algorithm for identifying women with polycystic ovary syndrome (PCOS) in the French national health data system.

Methods: Using data from the French national health data system, we applied the International Classification of Diseases (ICD-10) related diagnoses E28.2 for PCOS among women aged 18 to 43 years in 2021.

No impact of a positive Chlamydia trachomatis serology on live-birth rate after intra-uterine insemination.

Objective: To study the impact of a CT serology on intrauterine insemination (IUI) cumulative live-birth rate (cLBR) in women with documented bilateral tubal patency.

Design: Cohort study SUBJECTS: Infertile women with documented bilateral tubal patency and medical indication of IUI matched on the following criteria: woman's age, number of cycles completed and number of motile sperm inseminated (NMSI).

Exposure: This retrospective, observational and monocentric cohort study compared women with positive CT serology matched 1:1 to control women with negative CT serology.

Quality of life of chronically ill children and adolescents: a cross-sectional study.

Objective: The aim of this study was to describe the quality of life (QoL) of children with a chronic illness treated in a tertiary multidisciplinary pediatric department in comparison with the general population.

Study Design: A cross-sectional study was conducted in the tertiary multidisciplinary (nephrology, hepatogastroenterology, endocrinology, diabetology, transplantation) pediatric department of Timone Hospital in Marseille, France. Patients 8-17 years of age with a chronic disease were included during regular follow-up appointments.

Association of Standardized Parenteral Nutrition with Early Neonatal Growth of Moderately Preterm Infants: A Population-Based Cohort Study.

In preterm infants, early nutrient intake during the first week of life often depends on parenteral nutrition. This study aimed to evaluate the influence of standardized parenteral nutrition using three-in-one double-chamber solutions (3-in-1 STD-PN) on early neonatal growth in a cohort of moderately preterm (MP) infants. This population-based, observational cohort study included preterm infants admitted to neonatal centers in the southeast regional perinatal network in France.
