The influence of prenatal exercise modes on resting maternal blood lactate.

Resting lactate concentration in venous blood is a commonly used indicator of metabolic disease risk. Regular exercise during pregnancy improves maternal metabolic health; however, it is unknown if maternal exercise regulates resting lactate concentration. We aimed to elucidate the effects of three different modalities of exercise during pregnancy on blood lactate in pregnant women.

Exercise FITT-V during pregnancy: 1-month infant neuromotor outcomes.

Background: Despite decades of research documenting health benefits from exercise during pregnancy, it remains unknown how prenatal exercise affects infant neuromotor skill development.

Objectives: To examine the effects of exercise modes, and maternal exercise metrics; frequency, intensity, time, type, and volume (FITT-V) during pregnancy on infant gross motor skills. We hypothesized that 1 month old infants of mothers who exercised during pregnancy would exhibit more developed gross motor skills compared to infants of mothers who did not exercise during pregnancy.

Impact of Supervised-concurrent Exercise During Pregnancy on Infant Neuromotor Skills: A Post-hoc Analysis Stratified by Maternal BMI.

Background: This is a post-hoc secondary analysis of a randomized controlled trial whose purpose was to analyze the effect of a supervised-combined aerobic and resistance exercise (concurrent exercise) training program during pregnancy on 1-month infant neuromotor skills based on maternal pre-pregnancy body mass index (BMI).

Methods: Ninety-four pregnant women participated in this study, which was conducted at East Carolina University (Greenville, North Carolina, USA) between 2015 and 2018, and were allocated into concurrent exercise (n = 42) or stretching and breathing group (n = 52). The exercise group followed a 50-min 3 days/week moderate intensity concurrent exercise training program from the 16th gestational week until birth.

Exercise during pregnancy (frequency, intensity, type, time, volume): birth outcomes in women at risk of hypertensive disorders of pregnancy.

Background: Hypertensive disorders of pregnancy (HDP) hold negative health implications for mothers and offspring. While the beneficial influence of prenatal exercise on reducing HDP risk has been previously shown, there is a lack of specific information on the effect on birth outcomes in at-risk women, and in-depth analysis of appropriate exercise dose is lacking.

Objective: We aimed to elucidate the effects of exercise training FITT-V (frequency, intensity, type, time, volume) on hypertension and birth outcomes in pregnant women.

Anxiety-like behavior and altered hippocampal activity in a transgenic mouse model of Fabry disease.

Background: Fabry disease (FD) patients are known to be at high risk of developing neuropsychiatric symptoms such as anxiety, depression and cognitive deficits. Despite this, they are underdiagnosed and inadequately treated. It is unknown whether these symptoms arise from pathological glycosphingolipid deposits or from cerebrovascular abnormalities affecting neuronal functions in the central nervous system.

Consensus on the key characteristics of metabolism disruptors.

Metabolism-disrupting agents (MDAs) are chemical, infectious or physical agents that increase the risk of metabolic disorders. Examples include pharmaceuticals, such as antidepressants, and environmental agents, such as bisphenol A. Various types of studies can provide evidence to identify MDAs, yet a systematic method is needed to integrate these data to help to identify such hazards.

Effects of maternal exercise modes on infant cord blood proteome.

The aim of this study was to show the effects of different maternal exercise modes on infant cord blood proteome. We used infant cord blood from two randomized controlled trials where women with a wide range of BMI and free of pregnancy complications participated in controlled and supervised aerobic, resistance, or combination (aerobic+resistance) exercise from <16 weeks of gestation until delivery. Results of this study showed that infant cord blood proteome is altered in a maternal exercise mode specific manner.

Paternal obesity decreases infant MSC mitochondrial functional capacity.

Besides the well-recognized influence of maternal health on fetal in utero development, recent epidemiological studies appoint paternal preconception metabolic health as a significant factor in shaping fetal metabolic programming and subsequently offspring metabolic health; however, mechanisms behind these adaptations remain confined to animal models. To elucidate the effects of paternal obesity (P-OB) on infant metabolism in humans, we examined mesenchymal stem cells (MSCs), which give rise to infant tissue, remain involved in mature tissue maintenance, and resemble the phenotype of the offspring donor. Here, we assessed mitochondrial functional capacity, content, and insulin action in MSC from infants of fathers with overweight [body mass index (BMI: 25-30 kg/m); paternal overweight (P-OW)] or obesity (BMI ≥ 30 kg/m; P-OB) while controlling for maternal intrauterine environment.

Exercise during pregnancy Dose: Influence on preterm birth outcomes.

Background: Preterm delivery typically increases health risk for neonates and is associated with longer infant hospital stay and financial burden. Prenatal exercise dose (frequency, intensity, type, time, volume) have been shown to influence birth outcomes. Increased prenatal exercise dose could therefore provide a critical reduction in health risk and financial burden in preterm neonates.

Physiologically-based pharmacokinetic modeling of pantoprazole to evaluate the role of CYP2C19 genetic variation and obesity in the pediatric population.

Pantoprazole is a proton pump inhibitor indicated for the treatment of gastroesophageal reflux disease, a condition that disproportionately affects children with obesity. Appropriately dosing pantoprazole in children with obesity requires understanding the body size metric that best guides dosing, but pharmacokinetic (PK) trials using traditional techniques are limited by the need for larger sample sizes and frequent blood sampling. Physiologically-based PK (PBPK) models are an attractive alternative that can account for physiologic-, genetic-, and drug-specific changes without the need for extensive clinical trial data.

Exercise FITT-V during pregnancy: Association with birth outcomes.

Background: Prenatal exercise improves birth outcomes, but research into exercise dose-response effects is limited.

Methods: This study is a retrospective, secondary analysis of pooled data from three blinded, prospective, randomized controlled trials. Prenatal exercise frequency, intensity, type, time, and volume (FITT-V) were assessed in supervised sessions throughout pregnancy.

Molecular Transducers of Physical Activity Consortium (MoTrPAC): human studies design and protocol.

Physical activity, including structured exercise, is associated with favorable health-related chronic disease outcomes. Although there is evidence of various molecular pathways that affect these responses, a comprehensive molecular map of these molecular responses to exercise has not been developed. The Molecular Transducers of Physical Activity Consortium (MoTrPAC) is a multicenter study designed to isolate the effects of structured exercise training on the molecular mechanisms underlying the health benefits of exercise and physical activity.

Personalized Antihypertensive Treatment Optimization With Smartphone-Enabled Remote Precision Dosing of Amlodipine During the COVID-19 Pandemic (PERSONAL-CovidBP Trial).

Background: The objective of the PERSONAL-CovidBP (Personalised Electronic Record Supported Optimisation When Alone for Patients With Hypertension: Pilot Study for Remote Medical Management of Hypertension During the COVID-19 Pandemic) trial was to assess the efficacy and safety of smartphone-enabled remote precision dosing of amlodipine to control blood pressure (BP) in participants with primary hypertension during the COVID-19 pandemic.

Methods And Results: This was an open-label, remote, dose titration trial using daily home self-monitoring of BP, drug dose, and side effects with linked smartphone app and telemonitoring. Participants aged ≥18 years with uncontrolled hypertension (5-7 day baseline mean ≥135 mm Hg systolic BP or ≥85 mm Hg diastolic BP) received personalized amlodipine dose titration using novel (1, 2, 3, 4, 6, 7, 8, 9 mg) and standard (5 and 10 mg) doses daily over 14 weeks.

Do risk factors differentiate DSM-5 and drive for thinness severity groups for anorexia nervosa?

Background: The current study examined whether risk factors for anorexia nervosa (AN) were related to different levels of severity based on (a) the DSM-5/body mass index (BMI) and (b) drive for thinness (DT) severity ratings.

Methods: The sample comprised 153 pairs of individuals with a lifetime diagnosis AN per DSM-IV criteria and their non-ED sisters (N = 306, mean age = 26.53; mean current BMI = 20.

Per- and polyfluoroalkyl ether acids in well water and blood serum from private well users residing by a fluorochemical facility near Fayetteville, North Carolina.

Background: A fluorochemical facility near Fayetteville, North Carolina, emitted per- and polyfluoroalkyl ether acids (PFEAs), a subgroup of per- and polyfluoroalkyl substances (PFAS), to air.

Objective: Analyze PFAS in private wells near the facility and in blood from well users to assess relationships between PFEA levels in water and serum.

Methods: In 2019, we recruited private well users into the GenX Exposure Study and collected well water and blood samples.

Microglial activation, tau and amyloid deposition in TREM2 p.R47H carriers and mild cognitive impairment patients: a multi-modal/multi-tracer PET/MRI imaging study with influenza vaccine immune challenge.

Background: Microglia are increasingly understood to play an important role in the pathogenesis of Alzheimer's disease. The rs75932628 (p.R47H) TREM2 variant is a well-established risk factor for Alzheimer's disease.

Can we achieve better trial recruitment by presenting patient information through multimedia? Meta-analysis of 'studies within a trial' (SWATs).

Background: People need high-quality information to make decisions about research participation. Providing information in written format alone is conventional but may not be the most effective and acceptable approach. We developed a structure for the presentation of information using multimedia which included generic and trial-specific content.

Longitudinal Patterns of Beverage Intake in Treatment-Seeking Children with Obesity in Eastern NC Using the Validated BEVQ-15.

Sugar-sweetened beverage (SSB) consumption remains a major target for interventions to treat severe obesity in children. Understanding how total energy consumption is divided among different types of beverages remains unclear. This study retrospectively examined how the consumption of beverage calories (kcal) from 100% fruit juice and SSBs, and body mass index, assessed as a percent of the 95th sex- and age-specific percentile (%of 95BMI), changed during the treatment of children with obesity aged 2-18 years.
