BACKGROUND: Cardiopulmonary exercise testing is advised ahead of exercise intervention in obese adolescents to assess medical safety of exercise and physical fitness. Optimal validity and reliability of test results are required to identify maximal exercise effort. As fat oxidation during exercise is disturbed in obese individuals, it remains an unresolved methodological issue whether the respiratory gas exchange ratio (RER) is a valid marker for maximal effort during exercise testing in this population...

The consequences of childhood maltreatment are profound and long lasting. Not only does the victim of abuse suffer as a child, but there is mounting evidence that a history of maltreatment places the next generation at risk for significant psychopathology. Research identifies postnatal factors as affecting this intergenerational transmission of trauma. However, emerging evidence suggests that part of this risk may be transmitted before birth, passed on via abuse-related alterations in the in utero environment that are as yet largely unidentified...

BACKGROUND: -Glycerophosphocholine (GPC) metabolites modulate atherosclerosis and thus risk for cardiovascular disease (CVD). Pre-clinical CVD may start during adolescence. Here, we used targeted serum lipidomics to identify a new panel of GPCs, and tested whether any of these GPCs are associated - in adolescence - with classical risk factors of CVD, namely excess visceral fat (VF), elevated BP, insulin resistance and atherogenic dyslipidemia. METHODS: -We studied a population-based sample of 990 adolescents (12-18 years, 48% male), as part of the Saguenay Youth Study...

A number of chronic disease conditions tend to cluster in families with an increased risk in first-degree relatives, but also an increased risk in second-degree relatives. This fact is most often referred to as the heritability (heredity) of these diseases and explained by the influence of genetic factors, or shared environment, even if the more specific details or mechanism leading to disease are not known. New methods have to be explored in screening studies and register linkage studies to define and measure consequences of a positive family history of disease...

OBJECTIVE: The American Heart Association's (AHA) 2020 Strategic Goals defined a new concept of cardiovascular health (CVH) for adults and children, emphasizing the importance of early prevention of risk factors. CV disease risk factors track from childhood to adulthood, which should be closely monitored over time. However, detailed data on the trends in CVH among children are sparse. Therefore, by adopting the construct from the AHA, the present study seeks to evaluate the changes of ideal CVH, as well as each component, among Chinese children and adolescents in Beijing...

Hypertension in children and adolescents is associated with both short and long-term abnormalities in the cardiovascular system. Ultimately, these changes can lead to myocardial infarction, stroke, congestive heart failure and chronic renal disease, all of which are associated with substantial morbidity and mortality.In the short term, the best evidence that hypertension is adversely impacting the heart and vasculature is the development of left ventricular hypertrophy, increased vascular stiffness and endothelial dysfunction...

Adipokines are cytokines produced mainly by adipose tissue, besides many other tissues such as placenta, ovaries, peripheral-blood mononuclear cells, liver, muscle, kidney, heart, and bone marrow. Adipokines play a significant role in the metabolic syndrome and in cardiovascular diseases, have implications in regulating insulin sensitivity and inflammation, and have significant effects on growth and reproductive function. The objective of this review was to analyze the functions known today of adiponectin, leptin, resistin, and visfatin from placenta throughout childhood and adolescence...

OBJECTIVES: There have been conflicting data suggesting that prenatal mercury exposure is associated with adverse cardiovascular measures in children. We therefore analysed a large prospective population study to investigate whether prenatal mercury exposure might influence offspring blood pressure (BP) and heart rate adversely. DESIGN: Prospective birth cohort. SETTING: The Avon Longitudinal Study of Parents and Children (ALSPAC). PARTICIPANTS: Maternal whole blood collected in the first half of pregnancy was assayed for mercury and selenium...

Emotion regulation and associated autonomic activation develop throughout childhood and adolescence under the influence of the family environment. Specifically, physiological indicators of autonomic nervous system activity such as interoceptive sensitivity and vagally mediated heart rate variability (HRV) can inform on emotion regulation. Although the effect of parental emotion socialization on emotion regulation appears to be influenced by autonomic processes, research on physiological regulation and the influence of parental factors remains scarce...

Adults, older children, and adolescent patients with a BMI categorized as overweight or obese have decreased survival after HTx. Anthropometric correlates of survival after HTx in infants have not been well defined. In a retrospective analysis of the UNOS registry, patients age 0-24 months were classified according to the WHO height-for-age and weight-for-age norms, as well as arbitrary BMI-for-age percentiles. Outcomes of 1-year survival, conditional long-term survival, and cause-specific mortality were examined...

The pathological effects of exposure to an electromagnetic field (EMF) during adolescence may be greater than those in adulthood. We investigated the effects of exposure to 900 MHz EMF during adolescence on male adult rats. Twenty-four 21-day-old male rats were divided into three equal groups: control (Cont-Gr), sham (Shm-Gr) and EMF-exposed (EMF-Gr). EMF-Gr rats were placed in an EMF exposure cage (Plexiglas cage) for 1 h/day between postnatal days 21 and 59 and exposed to 900 MHz EMF. Shm-Gr rats were placed inside the Plexiglas cage under the same conditions and for the same duration, but were not exposed to EMF...
