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.

Educational outcomes in siblings of childhood leukemia survivors: Factors associated with school difficulties and comparison with general population.

Background: To investigate the educational outcomes of siblings of childhood leukemia survivors, explore determinants of school difficulties, and compare the rates of repeating grades between siblings and the general population.

Methods: A cross-sectional study of childhood leukemia survivors' siblings recruited through the Leucémies de l'Enfant et de l'Adolescent cohort, a French long-term follow-up program, was conducted, and education-related data were obtained via self-report questionnaires. Adjusted logistic regression models were used to identify variables associated with school difficulties and time since diagnosis.

Impact of a positive Chlamydia trachomatis serology on cumulative IVF live birth rate.

Research Question: Does positive Chlamydia trachomatis serology have an impact on the cumulative live birth rate from IVF?

Design: A retrospective matched cohort study compared women with positive Chlamydia trachomatis serology (group A) who underwent IVF treatment between January 2016 and December 2021 with a control group of women with negative Chlamydia trachomatis serology (group B). The main outcome measures were the cumulative live birth rate per IVF cycle and the live birth rate per embryo transfer. Secondary outcomes were the cumulative rates of clinical pregnancy, ectopic pregnancy and pregnancy loss calculated per IVF cycle and per embryo transfer.

Lifetime sexual violence experienced by women asylum seekers and refugees hosted in high-income countries: Literature review and meta-analysis.

Screening and care for victims of sexual violence (SV) among asylum seekers and refugees (ASRs) living in High-income host countries were prioritized by the WHO in 2020. The lack of stabilized prevalence findings on lifetime SV among ASRs in High-income countries hinders the development of adequate health management. The objective of this study was to determine the lifetime prevalence of SV experienced by ASRs living in High-income countries.

Effect of hormonal treatment on evolution of endometriomas: An observational study.

Objective: To evaluate the evolution of endometriomas with or without medical treatment.

Methods: This retrospective observational study was performed at the Gynaecological Center, Hôpital La Conception (Assistance Publique Hopitaux de Marseille). We reviewed clinical data of patients with at least one endometrioma diagnosed by magnetic resonance imaging (MRI) and at least one other MRI exam after more than three months.

Impact of moderate-to-severe endometriosis on IVF cumulative live birth rate: a retrospective matched cohort study.

Research Question: Does moderate-to-severe endometriosis have an impact on cumulative live birth rates (cLBR) and IVF outcomes?

Design: In this retrospective matched cohort study, women with moderate-to-severe endometriosis undergoing IVF or intracytoplasmic sperm injection treatment from January 2015 to December 2020 were matched 1:2 to women with other causes of infertility (control group). The main outcome was cLBR per cycle and per woman, and secondary outcomes were number of oocytes retrieved and number of mature oocytes, fertilization rate, total number of embryos and usable embryos, implantation rate, clinical pregnancy rate and miscarriage rate per cycle.

Results: In total, 195 women with endometriosis were matched with 390 women without endometriosis (323 and 646 cycles, respectively).

Impact of childhood leukemia on siblings: their long-term perception of family functioning and its relationship with their psychosocial characteristics using structural equation modeling.

Purpose: In the context of pediatric cancer, siblings' adaptation and needs have been previously investigated; however, research on the long-term consequences on siblings, especially on their family environment, is scarce. We aimed to (1) assess the family functioning (FF) perceived by siblings of childhood leukemia survivors long after diagnosis and (2) explore characteristics likely associated and investigate associations with psycho-behavioral and social factors.

Methods: Childhood leukemia survivors' siblings older than 11 years were recruited through the LEA cohort, a French long-term follow-up program, and completed the family assessment device (FAD).

Ovarian Function and Spontaneous Pregnancy After Hematopoietic Stem Cell Transplantation for Leukemia Before Puberty: An L.E.A. Cohort Study.

Ovarian function impairment and infertility are among the most frequent late effects after hematopoietic stem cell transplantation (HSCT). The aim of this study was to evaluate ovarian function, occurrence of premature ovarian insufficiency (POI), and spontaneous pregnancy in a large cohort of adult survivor women who had undergone HSCT for leukemia before puberty. We conducted a retrospective observational study in women from the national cohort L.

Impact of Early Hemoglobin Levels on Neurodevelopment Outcomes of Two-Year-Olds in Very Preterm Children.

Objective: To evaluate, in very preterm infants, the hemoglobin (Hb) levels during the first 24 h and the neurodevelopment outcomes at 24 months of corrected age.

Design, Setting, And Patients: We conducted a secondary analysis of the French national prospective and population-based cohort EPIPAGE-2. The eligible study participants were live-born singletons who were born before 32 weeks of gestational age, with early Hb levels who were admitted to the neonatal intensive care unit.

Predictors of Relapses or Recurrences in Patients With Giant Cell Arteritis: A Medical Records Review Study.

Objective: Giant cell arteritis (GCA) is the most common systemic vasculitis in individuals aged ≥50 years. Its course is marked by a high relapse rate requiring long-term glucocorticoid use with its inherent adverse effects. We aimed to identify factors associated with relapses or recurrences in GCA at diagnosis.

β-Thalassemia in childhood: Current state of health in a high-income country.

β-thalassemia is an haemoglobinopathy characterized by a defective synthesis of the β-globin chain. To assess the current state of health of paediatric patients with β-thalassemia, data from the French national registry regarding children born between 2005 and 2020 with β-thalassemia intermedia (TI) or major (TM) were collected. A total of 237 patients (median age 7.

Brothers and sisters of childhood acute leukemia survivors: Their long-term quality of life and its determinants.

Background: Childhood cancer confront the whole family with a traumatic event. Because brothers and sisters may encounter emotional problems that can remain for a long time and that only few studies have assessed their long-term outcome, our present objectives were to describe the long-term quality of life (QoL) of childhood leukemia survivors' siblings and to explore its determinant.

Methods: Brothers and sisters (from 8-year-old) of survivors included in the French LEA Cohort completed a QoL questionnaire (according to their age).

Individual and Family Determinants for Quality of Life in Parents of Children with Inborn Errors of Metabolism Requiring a Restricted Diet: A Multilevel Analysis Approach.

Objective: The objective of this study was to compare the quality of life (QoL) for parents of children with inborn errors of metabolism (IEMs) requiring a restricted diet with French population norms and investigate parental QoL determinants.

Study Design: This cross-sectional study included mothers and/or fathers of children < 18 years of age affected by IEMs requiring a restricted diet (except phenylketonuria) from January 2015 to December 2017. Parents' QoL was assessed using the World Health Organization Quality of Life BREF questionnaire and compared with age- and sex-matched reference values from the French general population.

A correlation between Magnetic Resonance Spectroscopy (1-H MRS) and the neurodevelopment of two-year-olds born preterm in an EPIRMEX cohort study.

Background: Preterm infants are at risk of neurodevelopmental impairments. At present, proton magnetic resonance spectroscopy (1H-MRS) is currently used to evaluate brain metabolites in asphyxiated term infants. The purpose of this study was to identify in the preterm EPIRMEX cohort any correlations between (1H-MRS) metabolites ratio at term equivalent age (TEA) and neurodevelopmental outcomes at 2 years.

Pregnancy outcomes after in vitro fertilization for moderate and severe endometriosis. A case-control study.

Introduction: Previous international studies showed that endometriosis could have a link with obstetrical complications, as an increased risk of preterm birth, gestational diabetes mellitus, and cesarean section. However, the results are difficult to interpret because biases are common, such as heterogeneity in the severity of the endometriosis cases included. That's why some complications as risk of miscarriage and post-partum hemorrhage are still debated.

Determinants of Quality of Life in Children with Inborn Errors of Metabolism Receiving a Restricted Diet.

Objective: To investigate the determinants of quality of life (QoL) in children with inborn errors of metabolism with restricted diet (IEMRDs) using a single theory-based multidimensional model.

Study Design: In this multicenter cross-sectional study, data from children aged 8-17 years with IEMRDs (except phenylketonuria) and their parents were collected from January 2015 to December 2017. Measurements included a child's self-reported QoL, self-rated behavioral problems and anxiety, and parental anxiety.

Copeptin assays in children for the differential diagnosis of polyuria-polydipsia syndrome and reference levels in hospitalized children.
