Dietary amino acids, macronutrients, vaginal birth, and breastfeeding are associated with the vaginal microbiome in early pregnancy.

Unlabelled: The vaginal microbiome is a key player in the etiology of spontaneous preterm birth. This study aimed to illustrate maternal environmental factors associated with vaginal microbiota composition and function in pregnancy. Women in healthy pregnancy had vaginal microbial sampling from the posterior vaginal fornix performed at 16 weeks gestation.

Associations of childhood physical activity and screen time with cardiometabolic health in preteens who were born to mothers with previous macrosomic delivery: Findings from the ROLO longitudinal birth cohort study.

Background: Macrosomia (birthweight ≥4 kg) may alter the associations of physical activity (PA) and screen time (ST) throughout childhood with later cardiometabolic risk.

Objective: To investigate associations of PA and ST over a 4-6-year follow-up period with cardiometabolic outcomes in preteens (9-11-year-olds) who were born to mothers with previous macrosomic delivery.

Methods: This is an analysis of 402 preteens from the ROLO study, who were born to mothers that previously delivered an infant with macrosomia.

The IRIS clinic: A Protocol for a mixed-methods study evaluating the management of Hyperemesis Gravidarum.

Background: Hyperemesis Gravidarum (HG) is a severe form of nausea and vomiting in pregnancy that affects 0.3-3% of women and has profound nutritional, physical and psychological consequences. Research is lacking regarding the most effective management of the condition.

Impact of previous pregnancy and BMI on cellular and serum immune activity from early to late pregnancy.

Immunological adaptions during pregnancy play a crucial role in healthy fetal development. Aberrant immune modifications however contribute to adverse pregnancy outcomes, which may be driven by maternal factors such as previous pregnancies and BMI. This secondary analysis of the MicrobeMom2 RCT investigates the changes to maternal inflammatory biomarkers derived from serum and stimulated peripheral blood mononuclear cells (PBMCs) during pregnancy, and the effects of previous pregnancies (parity) and BMI on maternal immune responses.

Recommendations on self-management interventions for adults living with obesity: COMPAR-EU project.

Self-management interventions (SMIs) may improve disease management in adults living with obesity. We formulated evidence-based recommendations for SMIs within the context of the COMPAR-EU project. The multidisciplinary panel selected critical outcomes based on the COMPAR-EU core outcome set and established decision thresholds for each outcome.

Stability of child appetitive traits and association with diet quality at 5 years and 9-11 years old: Findings from the ROLO longitudinal birth cohort study.

Background: We explored change in child appetitive traits from 5 to 9-11 years old and examined associations between appetitive traits at both timepoints and child diet quality.

Methods: This is secondary analyses of the ROLO longitudinal birth cohort study, including mother-child dyads from the 5 and 9-11-year old follow-up. The Children's Eating Behaviour Questionnaire measured child appetitive traits, with 167 children having matched data for both timepoints.

Diet quality and blood pressure among pregnant women with overweight or obesity: A secondary analysis of two randomized controlled trials.

Introduction: Maternal obesity is a significant risk factor for hypertensive disorders of pregnancy. High diet quality may protect against this, yet data regarding the relationship between diet quality and blood pressure among pregnant women with raised body mass index (BMI) is limited.

Material And Methods: This is a secondary analysis (n = 543) of women with BMI ≥25 kg/m from two randomized controlled trials; PEARS (Pregnancy Exercise and nutrition Research Study with smartphone application support) and ROLO (Randomized cOntrol trial of LOw glycemic index diet to prevent macrosomia in euglycemic women).

Multicomponent perinatal breastfeeding support in women with BMI >25: The Latch On multi-centre randomised trial.

Objective: To investigate the effectiveness of a multicomponent breastfeeding support intervention on breastfeeding prevalence at 3 months among women with a body mass index (BMI) >25 kg/m.

Design: Multicentre multicomponent randomised controlled trial.

Setting: Four maternity centres in Ireland.

Impact of Bifidobacterium longum1714® on maternal cytokine response in peripheral blood mononuclear cells.

Purpose: The maternal immune system is implicated in adverse pregnancy outcomes. Manipulation of maternal immune response by probiotics holds potential to reduce pregnancy complications. The MicrobeMom2 study investigates the impact of probiotic supplementation on maternal immune responses to pathogen associated molecular patterns (PAMPs) in peripheral blood mononuclear cells (PBMCs) during pregnancy.

The impact of macrosomia on cardiometabolic health in preteens: findings from the ROLO longitudinal birth cohort study.

Background: Macrosomia (birthweight ≥ 4 kg or ≥ 4.5 kg) is strongly associated with a predisposition to childhood obesity, which in turn is linked with adverse cardiometabolic health. Despite this, there is a lack of longitudinal investigation on the impact of high birthweight on cardiometabolic outcomes in youth.

Energy-Adjusted Dietary Inflammatory Index in pregnancy and maternal cardiometabolic health: findings from the ROLO study.

Background: Excessive inflammation during pregnancy has been linked to adverse long-term health outcomes for both mothers and their children. One such outcome is maternal cardiometabolic dysfunction. The Energy-Adjusted Dietary Inflammatory Index is a method of scoring the overall inflammatory potential of the diet.

Detailed mapping of Bifidobacterium strain transmission from mother to infant via a dual culture-based and metagenomic approach.

A significant proportion of the infant gut microbiome is considered to be acquired from the mother during and after birth. Thus begins a lifelong and dynamic relationship with microbes that has an enduring impact on host health. Based on a cohort of 135 mother-infant (F = 72, M = 63) dyads (MicrobeMom: ISRCTN53023014), we investigated the phenomenon of microbial strain transfer, with a particular emphasis on the use of a combined metagenomic-culture-based approach to determine the frequency of strain transfer involving members of the genus Bifidobacterium, including species/strains present at low relative abundance.

Ability of Bifidobacterium breve 702258 to transfer from mother to infant: the MicrobeMom randomized controlled trial.

Background: The composition of the infant microbiome can have a variety of short- and long-term implications for health. It is unclear if maternal probiotic supplementation in pregnancy can affect the infant gut microbiome.

Objective: This study aimed to investigate if maternal supplementation of a formulation of Bifidobacterium breve 702258 from early pregnancy until 3 months postpartum could transfer to the infant gut.

Pregnancy Nutrition Core Outcome Set (PRENCOS): A core outcome set development study.

Objective: To develop a core outcome set for pregnancy nutrition.

Design: Mixed-methods core outcome set development study.

Setting: Online.

Integrating nutrition and mental health screening, risk identification and management in prenatal health programs in India.

Pregnancy is a period of major physiologic, hormonal, and psychological change, increasing the risk of nutritional deficiencies and mental disorders. Mental disorders and malnutrition are associated with adverse pregnancy and child outcomes, with potential long-standing impact. Common mental disorders during pregnancy are more prevalent in low- and middle-income countries (LMICs).

Pregnancy complications and later life women's health.

There has been increasing recognition of the association between various pregnancy complications and development of chronic disease in later life. Pregnancy has come to be regarded as a physiological stress test, as the strain it places on a woman's body may reveal underlying predispositions to disease that would otherwise remain hidden for many years. Despite the increasing body of data, there is a lack of awareness among healthcare providers surrounding these risks.

Including the child's voice in research from a longitudinal birth cohort: insights from the ROLO young person's advisory group.

Background: Public and patient involvement (PPI) through Young Person's Advisory Groups (YPAG) enables children to provide guidance and insight into research activities. PPI is an important characteristic of research, however, to date, most collaboration has been with adults. Also, few YPAGs have been established within the Irish setting.

Associations between maternal metabolic parameters during pregnancy and fetal and child growth trajectories from 20 weeks' gestation to 5 years of age: Secondary analysis from the ROLO longitudinal birth cohort study.

Objective: To examine the association between maternal metabolic parameters in pregnancy and growth trajectories up to 5 years of age.

Methods: Data from mother-child pairs who participated in the ROLO study, a randomized trial examining the impact of a low glycaemic index diet on the recurrence of macrosomia, were analysed. Fetal and child growth trajectories were developed from longitudinal measurements from 20 weeks gestation up to 5 years of age.

Acceptability of the FIGO Nutrition Checklist in Preconception and Early Pregnancy to Assess Nutritional Status and Prevent Excess Gestational Weight Gain: A Study of Women and Healthcare Practitioners in the UK.

Optimum nutrition and weight before and during pregnancy are associated with a lower risk of conditions such as pre-eclampsia and gestational diabetes. There is a lack of user-friendly tools in most clinical settings to support healthcare practitioners (HCPs) in implementing them. This study aimed to evaluate the acceptability of (1) using a nutrition checklist designed by the International Federation of Gynecology and Obstetrics (FIGO) for nutritional screening of women in the preconception and early pregnancy period and (2) routine discussion of nutrition and weight in clinical care.
