Inter-pregnancy interval and uterine rupture during a trial of labour after one previous caesarean delivery and no previous vaginal births: a retrospective population-based cohort study.

Background: Short interpregnancy interval (IPI) following caesarean delivery is associated with uterine rupture in subsequent pregnancies. However, the interval required to minimise this risk is unknown. We investigated how the interval between pregnancies and induction or augmentation of labour affect the likelihood of uterine rupture among parturients with one previous livebirth by caesarean delivery who had a subsequent trial of labour.

A systematic review and meta-analysis of heat exposure impacts on maternal, fetal and neonatal health.

Climate change has severe and wide-ranging health impacts, especially for vulnerable groups. Despite growing evidence of heat-associated adverse maternal and neonatal health outcomes, there remains a lack of synthesis quantifying associations and identifying specific risk periods. We systematically reviewed the literature on heat impacts on maternal, fetal and neonatal health and quantified impacts through meta-analyses.

Impacts of heat exposure on pregnant women, fetuses and newborns: a systematic review and meta-analysis.

Climate Change has wide-ranging and severe health impacts, especially for vulnerable groups. We systematically reviewed the literature (n=198 studies) on heat impacts on maternal, fetal, and neonatal health, conducted meta-analyses to quantify impacts, analysed periods of susceptibility, and graded certainty. Studies covered 66 countries and 23 outcomes.

Cohort profile: the BABY1000 pilot prospective longitudinal birth cohort study based in Sydney, Australia.

Purpose: The health of parents prior to conception, a woman's health during pregnancy and the infant's environment across their first months and years collectively have profound effects on the child's health across the lifespan. Since there are very few cohort studies in early pregnancy, gaps remain in our understanding of the mechanisms underpinning these relationships, and how health may be optimised. 'BABY1000', a pilot prospective longitudinal birth cohort study, aims to (1) identify factors before and during pregnancy and early life that impact longer-term health and (2) assess the feasibility and acceptability of study design to inform future research.

Infants With Congenital Heart Disease at Risk of Early Atherosclerotic Disease.

Background Aortic intima-media thickness (aIMT) measurement is an established indicator of preclinical atherosclerosis. We aimed to describe the aIMT in infants with congenital heart disease undergoing cardiac surgery over the first year of life and explore its association with cardiopulmonary bypass, growth velocity, and a diagnosis of left heart obstruction. Methods and Results A prospective cohort study measuring mean and maximum aIMT preoperatively, at 3 months, and 1 year of age in neonates with congenital heart disease undergoing cardiac surgery.

Effects of Three Different Modes of Resistance Training on Appetite Hormones in Males With Obesity.

Purpose: This study explored the effect of three different modes of resistance training on appetite hormones [leptin, ghrelin, cholecystokinin (CCK), glucagon-like peptide-1 (GLP-1), and peptide tyrosine-tyrosine (PYY)], cardiometabolic and anthropometric measures in males with obesity.

Methods: Forty-four males with obesity (age: 27.5 ± 9.

The Effects of Aerobic-Resistance Training and Broccoli Supplementation on Plasma Dectin-1 and Insulin Resistance in Males with Type 2 Diabetes.

Background: This study aimed to evaluate the effects of a combination of aerobic-resistance training (CARET) and broccoli supplementation on dectin-1 levels and insulin resistance in men with type 2 diabetes mellitus (T2D).

Methods: Forty-four males with T2D were randomly allocated to four groups ( = 11 each group): CARET + broccoli supplement (TS), CARET + placebo (TP), control + broccoli supplement (S), and control + placebo (CP). CARET was performed three days per week for 12 weeks.

Medium-Chain Triglyceride Oil and Blood Lipids: A Systematic Review and Meta-Analysis of Randomized Trials.

Background: Dietary saturated fat raises total cholesterol and LDL cholesterol levels. It is unclear whether these effects differ by the fatty acid chain lengths of saturated fats; particularly, it is unclear whether medium-chain fatty acids increase lipid levels.

Objectives: We conducted a systematic review to determine the effects of medium-chain triglyceride (MCT) oil, consisting almost exclusively of medium-chain fatty acids (6:0-10:0), on blood lipids.

Impacts of High Environmental Temperatures on Congenital Anomalies: A Systematic Review.

Links between heat exposure and congenital anomalies have not been explored in detail despite animal data and other strands of evidence that indicate such links are likely. We reviewed articles on heat and congenital anomalies from PubMed and Web of Science, screening 14,880 titles and abstracts in duplicate for articles on environmental heat exposure during pregnancy and congenital anomalies. Thirteen studies were included.

Physical activity and adipokine levels in individuals with type 2 diabetes: A literature review and practical applications.

We review the effects of acute and long-term physical activity on adipokine levels in individuals with type 2 diabetes (T2D). Three electronic databases were searched. Studies made in animal models were excluded, while studies based on participants with and without T2D, and also studies with type 1 diabetes were included.

Associations between high temperatures in pregnancy and risk of preterm birth, low birth weight, and stillbirths: systematic review and meta-analysis.

Objective: To assess whether exposure to high temperatures in pregnancy is associated with increased risk for preterm birth, low birth weight, and stillbirth.

Design: Systematic review and random effects meta-analysis.

Data Sources: Medline and Web of Science searched up to September 2018, updated in August 2019.

Assessment of Central Arterial Hemodynamics in Children: Comparison of Noninvasive and Invasive Measurements.

Background: In adults, central systolic blood pressure (cSBP) and augmentation index (cAIx) are independently associated with cardiovascular events and mortality. There is increasing interest in central hemodynamic indices in children. We aimed to assess the accuracy of current techniques against invasive intra-aortic measurements in children.

Effect of Training Phase on Physical and Physiological Parameters of Male Powerlifters.

Longitudinal research on training and dietary practices of natural powerlifters is limited. This study investigated the effect of phases of training on physical and physiological parameters in male natural powerlifters. Nine participants completed testing at two time points: (i) preparatory phase (~3 months prior to a major competition) and (ii) competition phase (1-2 weeks from a major competition).

The effects of physical activity on adipokines in individuals with overweight/obesity across the lifespan: A narrative review.

This narrative review summarizes current knowledge on the effects of physical activity (PA) on adipokine levels in individuals with overweight and obesity. Approximately 90 investigations including randomized control, cross-sectional and longitudinal studies that reported on the effects of a single session of PA (acute) or long-term PA (chronic) on adipokine levels in individuals with overweight/obesity were reviewed. The findings support the notion that there is consensus on the benefits of chronic exercise training-regardless of the mode (resistance vs.

COVID-19 in Africa: care and protection for frontline healthcare workers.

Medical staff caring for COVID-19 patients face mental stress, physical exhaustion, separation from families, stigma, and the pain of losing patients and colleagues. Many of them have acquired SARS-CoV-2 and some have died. In Africa, where the pandemic is escalating, there are major gaps in response capacity, especially in human resources and protective equipment.

Relationship Between Disease Specific Quality of Life Measures, Physical Performance, and Activity in People with Intermittent Claudication Caused by Peripheral Artery Disease.

Objective: The aims of this study were firstly to assess the correlation between disease specific measures of quality of life (QOL) and physical performance and activity, and secondly to identify demographic, clinical, functional, and physical activity measures independently associated with QOL in people with intermittent claudication.

Methods: This was a cross sectional observational study of 198 people with intermittent claudication caused by peripheral artery disease who were recruited prospectively. QOL was assessed with the intermittent claudication questionnaire (ICQ) and the eight-theme peripheral artery disease quality of life questionnaire.

Effects of sprint interval or combined aerobic and resistance training on myokines in overweight women with type 2 diabetes: A randomized controlled trial.

Our primary aim was to assess the effects of two different training modalities: sprint interval training (SIT) or combined aerobic and resistance training (A + R) on circulating myokines related to metabolic profile and adiposity in type 2 diabetes (T2D). Fifty-two overweight women with T2D [55 ± 6 yrs., BMI 28.

Sociodemographic correlates of prospective dog owners' intentions to participate in controlled trials of dog ownership and human health.

Objective: Dog ownership is popular, with research suggesting improvements in physical and psychological health of dog owners. However, majority of these studies were not investigator-controlled. Ethical and practical implications arising from the intervention exposure (dog ownership) result in recruitment difficulties.

Cardiovascular Assessment in Human Research.

A number of noninvasive tests exist for assessing cardiovascular structure and function. This chapter describes protocols for flow-mediated dilation (FMD) of the brachial artery and pulse wave velocity (PWV) and pulse wave analysis (PWA) for measurement of arterial stiffness. The chapter also describes the different methodological approaches involved in applying these techniques for optimizing their validity, comparability, and potential uses as clinical and physiological research tools.

Obesity-related cardiovascular risk factors after long- term resistance training and ginger supplementation.

Obesity and its metabolic consequences are major risk factors for cardiovascular morbidity and mortality. However, lifestyle interventions, including exercise training and dietary components may decrease cardiovascular risk. Hence, this study was conducted to assess the effects of ginger supplementation and progressive resistance training on some cardiovascular risk factors in obese men.
