Understanding DOHaD Concepts Among New Zealand Adolescents: A Qualitative Exploration of Knowledge, Intervention Windows, and Information Accessibility.

The Developmental Origins of Health and Disease (DOHaD) framework has highlighted the role of maternal and paternal health on disease risk in offspring and across generations. Although adolescence is increasingly recognised as a key DOHaD window where interventions may have the greatest impact in breaking the cycle of non-communicable diseases, data around the recognition of this concept in adolescents remain limited. Previous work by our group found that the understanding of DOHaD-related concepts among adolescents in New Zealand was low, including some adolescents showing disagreement with key DOHaD concepts.

Development of a novel test of splenic function for use in a clinical diagnostic laboratory.

The spleen is prone to both physical damage and functional impairment, which can be difficult to detect before catastrophic complications occur. Currently available tests of splenic function are laborious, user-dependent and unreliable, so there is an unmet need for a reliable test offered routinely in diagnostic laboratories. In this study, we have assessed a simple flow cytometry-based method measuring high mannose glycans (HMGs) on erythrocytes, which has previously been proposed as a potential test of splenic function.

The prospective associations of fetal growth-related pregnancy complications with subsequent breastfeeding duration and markers of human milk production.

Background: The development of the breast for lactation occurs throughout pregnancy. It is unknown whether pregnancy complications resulting in poor fetal growth can affect breastfeeding (BF) success.

Objectives: We examined whether fetal growth-related pregnancy complications were associated with earlier BF cessation and changes in the concentrations of human milk biomarkers of low milk production.

Maternal Plasma miRNAs as Early Biomarkers of Moderate-to-Late-Preterm Birth.

Globally, preterm birth (PTB) is a primary cause of mortality and morbidity in infants, with PTB rates increasing worldwide over the last two decades. Biomarkers for accurate early prediction of PTB before the clinical event do not currently exist. Given their roles in the development and progression of many disease states, there has been increasing interest in the utility of microRNAs (miRNAs) as early biomarkers for pregnancy-related disorders, including PTB.

Comorbidity rates of autism spectrum disorder and functional neurological disorders: A systematic review, meta-analysis of proportions and qualitative synthesis.

Autism spectrum disorder (ASD) and functional neurological disorders (FND) are relatively common conditions, and there has been recent interest in the overlap between them. Both conditions share core features of alexithymia, impaired interoception and deficits in attentional focus. To date, relatively little is known about the comorbidity rates between ASD and FND.

Stimulant medications in the management of bulimia nervosa and anorexia nervosa in patients with and without comorbid attention deficit hyperactivity disorder: A systematic review.

Objective: People with attentional problems are at increased risk of eating disorders. This paper aimed to systematically review and synthesize the existing evidence on stimulant medication in the management of patients with bulimia nervosa (BN) or anorexia nervosa (AN) with or without comorbid attention deficit hyperactivity disorder (ADHD).

Method: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines.

EBV T-cell immunotherapy generated by peptide selection has enhanced effector functionality compared to LCL stimulation.

Adoptive immunotherapy with Epstein-Barr virus (EBV)-specific T cells is an effective treatment for relapsed or refractory EBV-induced post-transplant lymphoproliferative disorders (PTLD) with overall survival rates of up to 69%. EBV-specific T cells have been conventionally made by repeated stimulation with EBV-transformed lymphoblastoid cell lines (LCL), which act as antigen-presenting cells. However, this process is expensive, takes many months, and has practical risks associated with live virus.

Maternal high-fat diet during pregnancy and lactation affects factors that regulate cell proliferation and apoptosis in the testis of adult progeny.

Context A maternal high-fat diet is thought to pose a risk to spermatogenesis in the progeny. Aims We tested whether a maternal high-fat diet would affect Sertoli cell expression of transcription factors (insulin-like growth factor I (IGF-I); glial-cell line-derived neurotrophic factor (GDNF); Ets variant 5 (ETV5)) and cell proliferation and apoptotic proteins, in the testis of adult offspring. Methods Pregnant rats were fed ad libitum with a standard diet (Control) or a high-fat diet (HFat) throughout pregnancy and lactation.

A nutritional supplement during preconception and pregnancy increases human milk vitamin D but not B-vitamin concentrations.

Background & Aims: Optimal maternal vitamin status during pregnancy and lactation is essential to support maternal and infant health. For instance, vitamin D is involved in infant bone development, and B-vitamins are involved in various metabolic processes, including energy production. Through a double-blind randomised controlled trial, we investigated the effects of maternal supplementation from preconception throughout pregnancy until birth on human milk (HM) concentrations of vitamin D and B-vitamins.

Iron Supplementation in Management of Neurodevelopmental Disorders: Systematic Review, Meta-Analysis, and Qualitative Synthesis.

Objective: The authors sought to explore the role of iron supplementation in the management of neurodevelopmental disorders among children and youths.

Methods: A systematic review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was undertaken. A subset of results was suitable for meta-analysis.

A nutritional supplement taken during preconception and pregnancy influences human milk macronutrients in women with overweight/obesity and gestational diabetes mellitus.

Rational: Maternal overweight/obesity and gestational diabetes mellitus (GDM) are associated with an increased risk of their offspring developing overweight/obesity or type 2 diabetes later in life. However, the impacts of maternal overweight/obesity and dysglycemia on human milk (HM) macronutrient composition are not well understood.

Objective: Through a double-blind randomised controlled trial, we investigated the effects of maternal supplementation from preconception throughout pregnancy until birth on HM macronutrient concentrations, in association with maternal and infant factors including maternal pre-pregnancy body mass index (BMI) and GDM status.

Circulatory miRNAs as Correlates of Elevated Intra-Pancreatic Fat Deposition in a Mixed Ethnic Female Cohort: The TOFI_Asia Study.

Ectopic lipid accumulation, including intra-pancreatic fat deposition (IPFD), exacerbates type 2 diabetes risk in susceptible individuals. Dysregulated circulating microRNAs (miRNAs) have been identified as correlating with clinical measures of pancreatitis, pancreatic cancer and type 1 diabetes. The aim of the current study was therefore to examine the association between circulating abundances of candidate miRNAs, IPFD and liver fat deposition as quantified using magnetic resonance imaging (MRI) and spectroscopy (MRS).

Maternal Intake of Either Fructose or the Artificial Sweetener Acesulfame-K Results in Differential and Sex-Specific Alterations in Markers of Skin Inflammation and Wound Healing Responsiveness in Mouse Offspring: A Pilot Study.

Growing evidence has demonstrated that maternal artificial sweetener (AS) consumption may not be a beneficial alternative when compared to sugar-sweetened beverages and potentially leads to metabolic dysfunction in adult offspring. Compromised skin integrity and wound healing associated with type 2 diabetes can lead to complications such as diabetic pressure injury (PI). In this context, the skin plays an important role in the maintenance of metabolic homeostasis, yet there is limited information on the influence of sugar- or AS-sweetened beverages during pregnancy on developmental programming and offspring skin homeostasis.

Sustaining youth physical activity in times of challenge and change: lessons from COVID-19.

Physical activity (PA) is recognized as essential for positive physical and mental well-being in young people. However, participation in PA is known to decline as adolescents emerge into adulthood under the influence of complex social and structural factors. Globally, COVID-19 restrictions resulted in changes to PA and PA participation levels in youth populations, providing a unique opportunity for gaining insight into PA barriers and enablers in circumstances of challenge, limitation and change.

The growth hormone receptor interacts with transcriptional regulator HMGN1 upon GH-induced nuclear translocation.

Growth hormone (GH) actions are mediated through binding to its cell-surface receptor, the GH receptor (GHR), with consequent activation of downstream signalling. However, nuclear GHR localisation has also been observed and is associated with increased cancer cell proliferation. Here we investigated the functional implications of nuclear translocation of the GHR in the human endometrial cancer cell-line, RL95-2, and human mammary epithelial cell-line, MCF-10A.

A nutritional supplement containing zinc during preconception and pregnancy increases human milk zinc concentrations.

Introduction: During pregnancy and lactation minerals such as zinc are required to support maternal and infant health. Zinc is involved in various cellular processes, with requirements increasing in pregnancy and lactation. In the setting of a randomized trial, we investigated the effects on human milk (HM) zinc concentrations of a micronutrient-containing supplement including zinc in the intervention (but not control) group, started preconception and taken throughout pregnancy until birth.

Exploring the Retail Food Environment Surrounding Two Secondary Schools with Predominantly Pacific Populations in Tonga and New Zealand to Enable the Development of Mapping Methods Appropriate for Testing in a Classroom.

Rates of noncommunicable diseases (NCDs) are disproportionately high among people of Pacific ethnicity. Nutrition-related environmental exposures including food access and quality contribute to the matrix of factors impacting risk. Preventative interventions in adolescence and the opportunity to integrate health promotion into school-based learning are often overlooked.

Understanding the importance of the early-life period for adult health: a systematic review.

Evidence clearly indicates that the nutritional and non-nutritional environment and level of physical activity during the early-life period from preconception through infancy has a lifelong impact on the child's health. However this message must be communicated effectively to parents and other stakeholders such as grandparents, health professionals, policymakers and the wider community in order for positive change to occur. This systematic review explores how both awareness and understanding of the long-term effects of the early-life environment have been measured in various populations and whether any patterns are evident.

Glucocorticoids in preterm human milk.

Background: Glucocorticoids (GCs), cortisol and cortisone, are essential regulators of many physiological responses, including immunity, stress and mammary gland function. GCs are present in human milk (HM), but whether maternal and infant factors are associated with HM GC concentration following preterm birth is unclear.

Materials And Methods: HM samples were collected on postnatal day 5 and 10 and at 4 months' corrected age (4m CA) in a cohort of moderate- and late-preterm infants.

Fish oil supplementation of rats fed a high fat diet during pregnancy improves offspring insulin sensitivity.

Introduction: In rats, a maternal high-fat diet (HFD) leads to adverse metabolic changes in the adult offspring, similar to the children of mothers with obesity during pregnancy. Supplementation with a high dose of fish oil (FO) to pregnant rats fed a HFD has been shown to prevent the development of insulin resistance in adult offspring. However, the effects of supplementation at a translationally relevant dose remain unknown.

Sexual and Reproductive Health in Adolescents and Young Adults With Psychotic Disorders: A Scoping Review.

Background And Hypothesis: The sexual and reproductive health (SRH) of young people with psychosis has been largely overlooked. We hypothesised that there are key deficiencies in the existing literature on the SRH of adolescents and young adults with psychotic disorders.

Study Design: We conducted a systematic scoping review using Pubmed, Web of Science, Embase, PsycINFO, and CINAHL.

Voluntary physical activity in early life attenuates markers of fatty liver disease in adult male rats fed a high-fat diet.

Paediatric fatty liver disease (FLD) can develop into steatohepatitis, cirrhosis and hepatocellular carcinoma in adulthood. We assessed if early life physical exercise reduced the effects of high-fat (HF) diet-induced steatosis. Male HF-fed rats with access to a running wheel from weaning until day (D)60 (early exercise) or from D67 to D120 (late exercise) were compared with control HF- or chow-fed groups with no wheel.

Toxicity of oxidized fish oil in pregnancy: a dose-response study in rats.

Fish oil (FO) supplements are consumed during pregnancy to increase dietary omega-3. However, FO is often oxidized past recommended limits. In rats, a large dose of highly oxidized FO substantially increased newborn mortality, but the effects of human-relevant doses of less oxidized oil are unknown.
