Worldwide prevalence of atopic dermatitis in children between 2000 and 2021: A systematic analysis.

Background: Atopic dermatitis (AD) is a prevalent allergic disease that significantly impacts pediatric health.

Objective: To comprehensively describe the global, regional, and national AD prevalence trends among children aged 0 to 14 years between 2000 and 2021.

Methods: Data from the Global Burden of Disease Study 2021 were used to analyze AD prevalence and case numbers.

Understanding the Molecular Mechanisms of H2's Regulatory Effect on miR-29s for Brain Protection during Deep Hypothermic Circulatory Arrest.

Introduction: Research regarding post-operative brain protection after deep hypothermic circulatory arrest (DHCA) has gained attracted significant attention. We previously demonstrated that hydrogen can significantly reverse DHCA-induced brain damage.

Method: In the current research, we have established the DHCA model successfully using a modified four-vessel occlusion method and injected miR-29s compounds into the hippocampal tissue of rats.

The Correlation Between Severity of Postoperative Hypocalcemia and Perioperative Mortality in Chromosome 22q11.2 Microdeletion (22q11DS) Patient After Cardiac-Correction Surgery: A Retrospective Analysis.

Objectives: The aim of our study was to elucidate the association between severity of postoperative hypocalcemia and the prognosis of the patients with 22q11DS.

Methods: Data retrospectively were collected from 23 children with 22q11DS who underwent cardiac correction surgery. Area under the receiver operating characteristic curve (AUC) and diagnostic odds ratio were calculated to determine the tendency of perioperative mortality rate, according to the minimum levels of serum calcium and the duration of hypocalcemia.

The transfer of hydrogen from inert gas to therapeutic gas.

Hydrogen is the most abundant chemical element in the universe, and has been used as an inert gas for a long time. More recent studies have shown that molecular hydrogen as a kind of antioxidant, anti-inflammatory, anti-apoptosis, gene expression and signal modulation molecule, can be used for the treatment of many diseases. This review mainly focuses on the research progresses of hydrogen in various medical fields and the possible action mechanisms.
