Peer reviewers' conflicts of interest in biomedical research: scoping review.

Background: Peer review may improve the quality of research manuscripts and aid in editorial decisions, but reviewers can have conflicts of interest that impact on their recommendations.

Objectives: The objective was to systematically map and describe the extent and nature of empirical research on peer reviewers' conflicts of interest in biomedical research.

Design: Scoping review METHODS: In this scoping review, we included studies investigating peer reviewers' conflicts of interest in journal manuscripts, theses and dissertations, conference abstracts, funding applications and clinical guidelines.

Maternal Prepregnancy Obesity and Offspring Intelligence Quotient at 5 Years: A Multicohort Analysis.

Background: The relationship between maternal obesity and childhood cognitive development remains unclear. Prior studies did not adjust for important confounders, and preterm infants are a developmentally distinct group that remains scarcely examined.

Objectives: To determine whether maternal prepregnancy body mass index (BMI) is associated with offspring intelligence quotient (IQ) up to 5 years and whether this relationship varies with gestational age.

Obesity and postpartum hospital use among individuals without additional medical comorbidities.

Objective: The objective of this study was to examine whether obesity without preexisting or gestational comorbidities is associated with postpartum hospital use (PHU).

Methods: We studied 2016 to 2018 birth certificate and discharge data on 178,729 New York City births without International Classification of Diseases, Tenth Revision (ICD-10) codes at delivery for diabetes; hypertension; placental disease; anemia; thyrotoxicosis; bariatric surgery; and pulmonary, cardiac, renal, bleeding, autoimmune, digestive, neuromuscular, mental, or substance-use disorders. We defined PHU as ≥1 readmission or emergency department visit within 30 days of delivery discharge.

Methodological expectations for demonstration of health product effectiveness by observational studies.

The issue of assessing the effectiveness of health technologies (drugs, devices, etc.) through observational studies is becoming increasingly important as registration and market access agencies consider them in their evaluation process. In this context, observational studies must be able to provide real demonstrations of a level of reliability comparable to those produced by the conventional randomized controlled trial (RCT) approach.

Dietary exposure to mixtures of chemicals in the first year of life and allergic and respiratory diseases up to 8 years in the French EDEN mother-child cohort.

Exposure to environmental chemicals has been associated with higher risk of childhood allergies. This study aimed to examine the association between infant's dietary exposure to mixtures of chemicals and allergic and respiratory multimorbidity in childhood. Dietary exposures were assessed at 8 and 12 months in 724 and 745 children of the EDEN cohort.

Associations of language barriers with very preterm children's behavioural and socio-emotional problems across Europe.

Background: Very preterm birth (<32 weeks gestation, VP), immigrant background, and language barriers are all independently associated with a high risk for mental health problems in childhood, but research has neglected the long-term development of immigrant children born VP. We assessed whether behavioural and socio-emotional problems of 5-year-old children born VP growing up across different language contexts in the European Union are associated with an immigrant background and linguistic distance of families' mother tongue (L1) to the host countries' official languages.

Methods: Data are from a population-based cohort including all VP births in 2011/12 in 11 European countries; a total of 3,067 children were followed up at 2 and 5 years of age.

Characteristics of non-randomised studies of drug treatments: cross sectional study.

Objective: To examine the characteristics of comparative non-randomised studies that assess the effectiveness or safety, or both, of drug treatments.

Design: Cross sectional study.

Data Sources: Medline (Ovid), for reports published from 1 June 2022 to 31 August 2022.

Factors influencing language performance in boys and girls at age 2 in the French ELFE birth cohort.

Different environmental and biological variables affect the rhythm of language acquisition in children. A substantial amount of literature has shown that girls overtake boys, at least in the early stages of language acquisition. The goal of this study is to investigate how different factors affect language scores in girls and boys.

Persistent disabilities 28 months after COVID-19 hospitalisation, a prospective cohort study.

Background: Limited data are available on long-term respiratory disabilities in patients following acute COVID-19.

Patients And Methods: This prospective, monocentric, observational cohort study included patients admitted to our hospital with acute COVID-19 between 12 March and 24 April 2020. Clinical, functional and radiological data were collected up to 28 months after hospital discharge.

Timing of food pieces introduction and neurodevelopment: findings from a nationwide birth cohort.

Background: While complementary feeding can be challenging, little emphasis has been placed on the introduction to food texture/pieces, especially in terms of neurodevelopmental outcomes. This study aims to determine the association between the timing of introduction to food pieces during infancy and neurodevelopment in early childhood. We hypothesized that late introduction to food texture/pieces relates to unfavorable neurodevelopmental outcomes.

Identifying psychosocial and contextual markers considered by physicians to personalize care.

Background: The objective of the study was to identify the psychosocial and contextual markers considered by physicians to personalize care.

Methods: An online questionnaire with one open-ended question, asking physicians to describe clinical situations in which they personalized care, was used. Physicians were recruited from March 31, 2023, to August 10, 2023, from three hospitals, five university departments of general practice and six physician organizations in France.

A web-based and mobile randomised controlled trial providing complementary feeding guidelines to first-time parents in France to promote responsive parental feeding practices, healthy children's eating behaviour and optimal body mass index: the NutrienT trial study protocol.

Background: Childhood obesity is a crucial public health issue. Early childhood is a critical time to foster the establishment of healthy eating behaviours and growth, which are partly shaped by parental feeding practices. To inform French parents of the recently updated national complementary feeding guidelines for 0-3 years (in terms of nutrition and responsive feeding as a mean to encourage infant appetite control skills and promote healthy growth), an official printed brochure was developed and nationally disseminated in 2021 by the French public health agency, Santé publique France.

A cross-sectional study assessing visual abstracts of randomized trials revealed inadequate reporting and high prevalence of spin.

Objectives: Visual abstracts (VAs) lack study-specific reporting guidelines and are increasingly used as stand-alone sources in medical research dissemination although not designed for this purpose. Therefore, our objectives were to describe 1) completeness of reporting in VAs and corresponding written abstracts (WAs) of randomized controlled trials (RCTs), and 2) the extent and type of spin (ie, any reporting pattern that could distort result interpretation and mislead readers) in VAs and WAs of RCTs with a statistically nonsignificant primary outcome.

Study Design And Setting: We conducted a cross-sectional study evaluating VAs and WAs of RCTs published between January 1, 2021, and March 3, 2023.

Maternal social deprivation and preterm birth: The PreCARE cohort study.

Background: Maternal exposure to unfavourable social conditions is associated with a higher rate of perinatal complications, such as placental vascular pathologies. A higher risk of preterm birth (PTB) has also been reported, and variations across studies and settings suggest that different patterns may be involved in this association.

Objective: To assess the association between maternal social deprivation and PTB (overall and by phenotype).

Nicotine dependence and incident psychiatric disorders: prospective evidence from US national study.

We examined the prospective associations between nicotine dependence and the likelihood of psychiatric and substance use disorders in the general adult population. Participants came from a nationally representative sample of US adults aged 18 years or older, who were interviewed 3 years apart in the National Epidemiologic Survey on Alcohol and Related Conditions (Wave 1, 2001-2002; Wave 2, 2004-2005). The primary analyses were limited to 32,671 respondents (13,751 male (47.

Health-related quality of life at 5 years of age for children born very preterm with congenital anomalies: a multi-national cohort study.

Background: This study aimed to investigate the health-related quality of life (HRQoL) at 5 years of age of European children born very preterm across multi-dimensional outcomes by presence and severity of congenital anomalies.

Methods: The study used data from a European cohort of children born very preterm (<32 weeks of gestation) and followed up to 5 years of age (N = 3493). Multilevel Ordinary Least Squares (OLS) regression were used to explore the associations between the presence and severity of congenital anomalies.

Hair cortisol concentrations across pregnancy and maternal postpartum depressive symptoms - The ELFE cohort.

Postpartum depression and depressive symptoms have a major impact on maternal and infant health and well-being, yet to date their aetiology remains unclear. One hypothesis suggests a link between these symptoms and variations in prenatal cortisol levels, but existing evidence is limited and inconclusive. This study aims to provide additional evidence to disentangle the relationship between prenatal cortisol concentrations and subsequent occurrence of postpartum depressive symptoms.
