Background: We aimed to explore simple and effective clinical parameters or combinations to predict coronary artery dilation and aneurysm formation in pediatric patients with Kawasaki disease (KD).

Design And Methods: This retrospective cohort study included pediatric patients with KD from January, 2013 to December, 2022. Multiple demographic and clinical data were collected, collated, and calculated from the medical records.

Over the past decade, immunotherapies have brought about significant changes in how we approach the treatment of various solid tumors and blood-related cancers. However, the effectiveness of checkpoint blockade therapy has been constrained to a rate of under 30 %. A significant challenge in the realm of tumor immunotherapy revolves around comprehending the mechanisms through which regulatory T (Treg) cells induce immunosuppression.

Article Synopsis
  • - The study evaluated antibiotic prescription patterns for neonates in China, referencing the WHO's AWaRe framework and MAC Guidelines, and was conducted through point-prevalence surveys from 2017 to 2019.
  • - Data from 2674 neonatal patients showed that 1520 received antibiotics, with meropenem being the most prescribed, and pneumonia being the primary reason for prescriptions (44.2%).
  • - Findings suggest that there is an overuse of broad-spectrum antibiotics categorized in the Watch and Special groups, with a significant number of prescriptions falling under the Restricted category according to the MAC Guidelines.

Objectives: Use of Broad-spectrum antibiotics is related closely to increasing antimicrobial resistance. Reports on antibiotic prescriptions for Chinese children were rare. We described the prescribing patterns of antibiotic prescriptions for Chinese children from 2017 to 2019 based on the Anatomical Therapeutic Chemical Classification (ATC classification); the Access, Watch, and Reserve (AWaRe) classification from the World Health Organization (WHO), and the Management of Antibiotic Classification in China.

Background: Recent studies indicate that increased expression of glyoxalase I (GLO1) could result in epileptic seizures; thus, this study further explored the association of GLO1 with epilepsy from the perspective of molecular genetics.

Material And Methods: GLO1 single nucleotide polymorphisms (SNPs; rs1130534, rs4746 and rs1049346) were investigated in cohort I (the initial samples: 249 cases and 289 controls). A replication study designed to confirm the positive findings in cohort I was performed in cohorts II (the additional samples: 130 cases and 191 controls) and I+II.

Background: Human beta-defensin-3 (HBD(3)) is an epithelial peptide that has been demonstrated to have a salt-insensitive broad spectrum of potent antimicrobial activity. Expressing antimicrobial peptides in Escherichia coli (E. coli) is very difficult for it can result in death of the bacterial host cells.
