Supplementation practices among pregnant women and those trying to conceive: a population-representative survey in Vancouver, Canada.

Dietary supplements including vitamins, minerals, and natural health products are commonly consumed by those aiming to optimize fertility and pregnancy outcomes. The aim of this survey was to describe supplementation practices among individuals who were pregnant or trying to conceive in Vancouver, Canada. An online survey was conducted among 500 individuals who were pregnant ( = 250) or trying to conceive ( = 250).

Cardiomyocyte crosstalk with endothelium modulates cardiac structure, function, and ischemia-reperfusion injury susceptibility through erythropoietin.

Erythropoietin (EPO) exerts non-canonical roles beyond erythropoiesis that are developmentally, structurally, and physiologically relevant for the heart as a paracrine factor. The role for paracrine EPO signalling and cellular crosstalk in the adult is uncertain. Here, we provided novel evidence showing cardiomyocyte restricted loss of function in in adult mice induced hyper-compensatory increases in expression by adjacent cardiac endothelial cells via HIF-2α independent mechanisms.

Prospective manipulation of the gut microbiome with microbial ecosystem therapeutic 4 (MET4) in HPV-related locoregionally-advanced oropharyngeal cancer squamous cell carcinoma (LA-OPSCC) undergoing primary chemoradiation: ROMA2 study.

Background: Gut microbiome modulation to boost antitumor immune responses is under investigation.

Methods: ROMA-2 evaluated the microbial ecosystem therapeutic (MET)-4 oral consortia, a mixture of cultured human stool-derived immune-responsiveness associated bacteria, given with chemoradiation (CRT) in HPV-related oropharyngeal cancer patients. Co-primary endpoints were safety and changes in stool cumulative MET-4 taxa relative abundance (RA) by 16SRNA sequencing.

Optimizing vitamin D status in polycystic ovary syndrome: a systematic review and dose-response meta-analysis.

Context: Polycystic ovary syndrome (PCOS) is a common and complex endocrine disorder in women of reproductive age. Vitamin D supplementation is a promising complementary therapy for PCOS, yet there is no consensus on an optimal dose, leading to a lack of evidence-based supplementation guidelines.

Objective: The objective of this study was to conduct a vitamin D dose-response meta-analysis among women with PCOS.

Supplementation with (6)-5-methyltetrahydrofolic acid appears as effective as folic acid in maintaining maternal folate status while reducing unmetabolised folic acid in maternal plasma: a randomised trial of pregnant women in Canada.

Folic acid supplementation is recommended during pregnancy to support healthy fetal development; (6)-5-methyltetrahydrofolic acid ((6)-5-MTHF) is available in some commercial prenatal vitamins as an alternative to folic acid, but its effect on blood folate status during pregnancy is unknown. To address this, we randomised sixty pregnant individuals at 8-21 weeks' gestation to 0·6 mg/d folic acid or (6)-5-MTHF × 16 weeks. Fasting blood specimens were collected at baseline and after 16 weeks (endline).

Three-dimensional feedback processes in current-driven metal.

Using three-dimensional (3D) magnetohydrodynamic simulations, we study how a pit on a metal surface evolves when driven by intense electrical current density j. Redistribution of j around the pit initiates a feedback loop: j both reacts to and alters the electrical conductivity σ, through Joule heating and hydrodynamic expansion, so that j and σ are constantly in flux. Thus, the pit transforms into larger striation and filament structures predicted by the electrothermal instability theory.

Human milk unmetabolized folic acid is increased following supplementation with synthetic folic acid as compared to (6S)-5-methyltetrahydrofolic acid.

Folic acid supplementation is recommended perinatally, but may increase unmetabolized folic acid (UMFA) in human milk; this is concerning as it is an inactive form which may be less bioavailable for the infant. "Natural" (6S)-5-methyltetrahydrofolic acid [(6S)-5-MTHF] is available as an alternative to folic acid, and may prevent the accumulation of UMFA in human milk. Pregnant women (n = 60) were enrolled at 8-21 weeks of gestation and randomized to 0.

gen. nov. sp. nov., isolated from a human clinical sample.

The diversity of bacteria associated with biopsy material obtained from patients with colorectal cancer was investigated using culture techniques. A novel bacterium, strain CC70A, was isolated by diluting a sample of homogenized tissue in anaerobic medium, and then plating to yield a pure culture. Strain CC70A was a Gram-positive, strictly anaerobic, motile, rod-shaped bacterium.

Seeding the Electrothermal Instability through a Three-Dimensional, Nonlinear Perturbation.

Electrothermal instability plays an important role in applications of current-driven metal, creating striations (which seed the magneto-Rayleigh-Taylor instability) and filaments (which provide a more rapid path to plasma formation). However, the initial formation of both structures is not well understood. Simulations show for the first time how a commonly occurring isolated defect transforms into the larger striation and filament, through a feedback loop connecting current and electrical conductivity.

A microbial consortium alters intestinal and antimicrobial resistance genes in individuals with recurrent infection.

Intestinal colonization with pathogens and antimicrobial-resistant organisms (AROs) is associated with increased risk of infection. Fecal microbiota transplant (FMT) has successfully been used to cure recurrent infection (rCDI) and to decolonize intestinal AROs. However, FMT has significant practical barriers to safe and broad implementation.

Cow's milk alternatives for children with cow's milk allergy and beyond.

Cow's milk allergy (CMA) is one of the most common food allergies in the first years of life, with worldwide prevalence estimated to range from 2% to 5%. While the majority of children with CMA will eventually develop tolerance to cow's milk proteins (it is estimated that >75% of children with CMA develop tolerance to cow's milk proteins by the age of 3 years, and >90% develop tolerance by the age of 6 years), the selection of an appropriate cow's milk (CM) alternative for those with CMA is vital to ensure adequate growth and development during childhood. The increasing number of CM alternative products on the commercial market with markedly different nutritional content and micronutrient fortification adds a layer of complexity that can be challenging for both families and clinicians to navigate.

First-in-class Microbial Ecosystem Therapeutic 4 (MET4) in combination with immune checkpoint inhibitors in patients with advanced solid tumors (MET4-IO trial).

Background: The intestinal microbiome has been associated with response to immune checkpoint inhibitors (ICIs) in humans and causally implicated in ICI responsiveness in animal models. Two recent human trials demonstrated that fecal microbiota transplant (FMT) from ICI responders can rescue ICI responses in refractory melanoma, but FMT has specific limitations to scaled use.

Patients And Methods: We conducted an early-phase clinical trial of a cultivated, orally delivered 30-species microbial consortium (Microbial Ecosystem Therapeutic 4, MET4) designed for co-administration with ICIs as an alternative to FMT and assessed safety, tolerability and ecological responses in patients with advanced solid tumors.

Family Quality of Life Perceived by Mothers of Children with ASD and ADHD.

Existing research has compared Family Quality of Life (FQOL) in autism spectrum disorder (ASD) populations and typically developing populations but has not yet explored differences in FQOL across ASD, attention-deficit/hyperactivity disorder (ADHD), and comorbid ASD and ADHD populations (ASD + ADHD). In the present study, 117 North American mothers of 92 sons and 25 daughters (ages 6-11) with ASD, ADHD, or ASD + ADHD completed an online survey exploring FQOL. An ANOVA failed to show group differences in overall FQOL, however, mothers of children with ASD + ADHD reported significantly lower family Emotional Well-being than mothers of children with ASD only.

Iron-Deficiency Prevalence and Supplementation Practices Among Pregnant Women: A Secondary Data Analysis From a Clinical Trial in Vancouver, Canada.

Background: North American public health guidelines recommend supplementation with an iron-containing prenatal multivitamin throughout pregnancy to meet the RDA of 27 mg of elemental iron daily. However, whether supplementation with standard prenatal multivitamins is sufficient to prevent maternal iron deficiency is unclear, as needs increase substantially with advancing gestation.

Objectives: This study aimed to assess iron status in early and late pregnancy among 60 pregnant women receiving 27 mg/day of elemental iron as part of a randomized trial in Vancouver, Canada.

Strategies for improving recruitment of pregnant women to clinical research: An evaluation of social media versus traditional offline methods.

Objectives: To evaluate the recruitment of pregnant women for a clinical trial in Vancouver, Canada, via social media versus offline methods and to explore optimization of social media campaigns.

Methods: Facebook was used to run nine social media campaigns (15 weeks total, CA$675). Offline methods were used concurrently over 64 weeks (printing costs: CA$300).

Pregnancy-induced alterations of 1-carbon metabolism and significance for maternal nutrition requirements.

Objectives: The pregnancy-induced alterations in 1-carbon (1C) metabolism, effects of advancing gestation on maternal plasma concentrations of methyl nutrients, and potential implications for maternal dietary intake and infant clinical outcomes are summarized in this narrative review.

Background: 1C metabolism encompasses a series of pathways where 1C units are transferred among nutrients such as B vitamins, choline, and amino acids (the methyl nutrients). Use of isotopic tracers and measuring methyl nutrients in maternal plasma and infant cord blood has advanced the understanding of 1C flux in pregnancy and kinetics of maternal-placental-fetal transfer.

Spin-dependent vibronic response of a carbon radical ion in two-dimensional WS.

Atomic spin centers in 2D materials are a highly anticipated building block for quantum technologies. Here, we demonstrate the creation of an effective spin-1/2 system via the atomically controlled generation of magnetic carbon radical ions (CRIs) in synthetic two-dimensional transition metal dichalcogenides. Hydrogenated carbon impurities located at chalcogen sites introduced by chemical doping are activated with atomic precision by hydrogen depassivation using a scanning probe tip.

ISA API: An open platform for interoperable life science experimental metadata.

Background: The Investigation/Study/Assay (ISA) Metadata Framework is an established and widely used set of open source community specifications and software tools for enabling discovery, exchange, and publication of metadata from experiments in the life sciences. The original ISA software suite provided a set of user-facing Java tools for creating and manipulating the information structured in ISA-Tab-a now widely used tabular format. To make the ISA framework more accessible to machines and enable programmatic manipulation of experiment metadata, the JSON serialization ISA-JSON was developed.

The Enzyme Portal: an integrative tool for enzyme information and analysis.

Enzymes play essential roles in all life processes and are used extensively in the biomedical and biotechnological fields. However, enzyme-related information is spread across multiple resources making its retrieval time-consuming. In response to this challenge, the Enzyme Portal has been established to facilitate enzyme research, by providing a freely available hub where researchers can easily find and explore enzyme-related information.

Determining the electrical conductivity of metals using the 2 MA Thor pulsed power driver.

We present the development of a pulsed power experimental technique to infer the electrical conductivity of metals from ambient to high energy density conditions. The method is implemented on Thor, a moderate scale (1-2 MA) pulsed power driver. The electrical conductivity of copper at elevated temperature (>4000 K) and pressure (>10 GPa) is determined, and a new tabular material model is developed, guided by density functional theory, which preserves agreement with existing experimental data.
