Abstract

This cross-sectional study investigates the relationship between gestational age and systolic blood pressure and pulse pressure in childhood. Blood pressure was measured in 483 schoolchildren, free from cardiovascular disease, aged between 6 and 16 years. Pulse pressure was estimated as the difference between the 24-h mean systolic and diastolic blood pressure values. Linear regression showed an inverse relationship between gestational age and mean 24-h systolic blood pressure (adjusted regression coefficient mm Hg per week gestation -0.631, 95% confidence interval (CI) -1.21 to -0.04, P=0.036). Further, linear regression showed a significant negative association between gestational age and log-transformed pulse pressure (adjusted antilog regression coefficient mm Hg per week of gestation -1.39, 95% CI -2.96 to -0.3, P=0.013), which after gender-specific analyses was found to be restricted to the girls in the study. The results of the present study suggest that low gestational age is associated with elevated systolic blood pressure and pulse pressure in childhood, the latter particularly in girls. This observation provides some support for the developmental origins of adult disease hypothesis-that adverse events in early life m...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain.
