Background: Tranexamic acid (TXA) plays a central role in antifibrinolytic strategies, raising intense concerns regarding TXA-associated seizures. The aim of the study was to develop an in vivo TXA-induced seizure (TIS) model and identify its features on behavior, electroencephalograph (EEG), histology, and metabolomics.

Methods: Adult healthy male C57BL/6J mice (n = 42) were randomized into 7 dosage groups to receive intracerebroventricular injection of TXA (vehicle, 1, 5, 7.

The impact of mother-infant microbiota on neurodevelopment is an area of interest, but longitudinal studies are scarce. Using a cohort of 520 families from the Jiangsu birth cohort in China, we reveal that the maternal gut microbiota during early pregnancy play a substantial role, accounting for 3.34% of the variance in offspring neurodevelopmental scores.

A lot of endogenous genes, as well as genes from related species, are transformed back into crops for overexpression to improve their corresponding traits. However, almost all of these transgenic events remain at the testing stage. Most of the singular transgenic events of crops approved for commercial release are developed by the transformation and heterologous expression of exogenous genes from distant species.

Background: The elderly ulcerative colitis (UC) patients pose unique challenges due to their comorbidities, diminished functional capacity, and heightened risk of treatment-related complications. Thus, finding a safe and effective treatment for this age group is crucial.

Aim: This study investigates the role of autophagy in the pathogenesis of UC in young and elderly patients, and explores the therapeutic potential and mechanisms of autophagy modulators in aged mice with dextran sulfate sodium (DSS)-induced colitis.

Article Synopsis
  • A new mRNA vaccine for tuberculosis (TB) shows strong effectiveness in a zebrafish model, offering both prevention and treatment benefits.
  • Zebrafish that received the mRNA vaccine lived longer after being exposed to TB and showed significantly reduced bacterial levels when treated after infection.
  • The vaccine not only activates important DNA repair systems for immune function but also promotes cell survival and bacterial killing without triggering harmful cell death responses.

Introduction: The association between breastfeeding status and early childhood caries (ECC) remains inconclusive. Few studies evaluate the breastfeeding status including both duration and exclusivity according to the WHO recommendations on breastfeeding. This study aimed to investigate the association between breastfeeding status and ECC.

Objective: To investigate the prevalence of autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC), and the impact of comorbidity of AIH, PBC, and PSC on hospitalization burden in patients with inflammatory bowel disease (IBD).

Methods: Inpatients admitted to Peking Union Medical College Hospital from January 1, 1998 to December 31, 2021 were included. Odds ratio (OR) and the corresponding 95% confidence interval (CI) were calculated to compare the risk of AIH, PBC, and PSC between IBD and non-IBD patients.

The safety and clinical effectiveness of preimplantation genetic testing for aneuploidy (PGT-A) in improving pregnancy outcomes for sub-fertile patients remains controversial. Potential sex-based differences in the relationship between PGT-A and pregnancy complications have not been investigated, which could guide the appropriate clinical application of PGT-A. In this secondary analysis of data from a multicenter, randomized, controlled, non-inferiority trial (NCT03118141), 940 women who achieved singleton live birth during the trial were included to estimate the between-group differences in pregnancy complications following PGT-A versus conventional fertilization (IVF) vary with fetal sex.

Objective: We sought to explore the linear or nonlinear relationship between preoperative iron metabolism and acute kidney injury following cardiac surgery (CSA-AKI) with cardiopulmonary bypass (CPB).

Methods: Patients who underwent cardiac surgery with CPB between December 2018 and April 2021 were retrospectively collected from Fuwai Hospital and Medical Information Mart for Intensive Cared dataset (MIMIC-IV). The measurements of iron metabolism included serum iron (SI), serum ferritin (SF), transferrin (TRF), transferrin saturation (TS), and total iron binding capacity (TIBC).

Objectives: To investigate the association of infant sleep and sleep trajectories through the first year of life with infant neurodevelopment.

Methods: This study was conducted with 3251 infants in China. Sleep parameters were evaluated by the Brief Infant Sleep Questionnaire at 42days, 6months, and 1year of age.

Article Synopsis
  • The study aimed to identify clinical characteristics of patients with post-neurosurgical meningitis (PNM) and analyze factors predicting mortality.
  • Over 70,000 neurosurgical patients were evaluated, with a focus on about 900 PNM cases, revealing a 28-day mortality rate of 12.4% and key mortality predictors including hypertension and drainage procedures.
  • Results suggested that treatment with three or more antibiotics significantly improves patient outcomes compared to dual-drug treatments.

  • Recent studies suggest that titanium exposure may negatively affect glucose metabolism, but its link to gestational diabetes mellitus (GDM) is not well-studied.
  • A study involving 1,449 pregnant women in China found that higher levels of urinary titanium in early pregnancy were associated with a 30% increased risk of developing GDM.
  • The research identified specific metabolites (choline, creatine, and L-alanine) involved in amino acid metabolism that may help explain how titanium exposure influences GDM risk.

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) is related to increased morbidity and mortality. However, limited studies have explored the influence of different feature selection (FS) methods on the predictive performance of CSA-AKI. Therefore, we aimed to compare the impact of different FS methods for CSA-AKI.

  • The Maternal Immune Activation (MIA) theory indicates that inflammation during pregnancy may link maternal adversities to neurodevelopmental issues in children.
  • A study analyzed 3,051 infants using a newly created Inflammation related Prenatal Adversity Index (IPAI) and assessed their neurodevelopment through standardized tests at one year old.
  • Results showed that infants in the "high IPAI" group scored significantly lower in cognitive skills and communication compared to those in the "low IPAI" group, indicating a higher risk of developmental delays.

Article Synopsis
  • The study investigated how preoperative iron metabolism affects the risk of perioperative myocardial injury (PMI) in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB).
  • Researchers analyzed data from 744 eligible patients, finding a 25.7% incidence of PMI, and discovered that there was no significant linear relationship between iron metabolism measures and PMI.
  • The analysis revealed a gentle U-shaped relationship indicating that while increasing transferrin (TRF) and total iron-binding capacity (TIBC) can initially reduce the risk of PMI, further increases in these measures may increase the risk again, particularly in older patients.

Objectives: This study explores how vascular stenosis and absence affect the regulation of cerebral blood flow in the Circle of Willis (CoW) and the hemodynamic changes downstream of the stenosis.

Materials And Methods: Forty idealized CoW models were simulated to analyze the impact of vascular absence and internal carotid artery (ICA) stenosis on hemodynamics. Inlet conditions were set using a physiological pressure waveform, and outflow boundaries were modeled using three-element Windkessel models.

Background: The chemokine receptor CXCR6 is critical for sustained tumor control mediated by CD8+ cytotoxic T cells (CTLs) in tumors. Previous studies have shown that ionizing radiation induces an inflamed immune contexture by upregulating CXCR6. However, the clinical significance of CXCR6 expression in triple-negative breast cancer (TNBC) and its correlation with radiotherapy remains unknown.

  • Maternal hypertensive disorders in pregnancy (HDP) may increase the risk of strabismus (crossed eyes) in children, but the specific relationship remains unclear.
  • A study involving over 3,000 children examined the effects of maternal HDP on strabismus and found that those exposed to maternal HDP were 82% more likely to develop the condition, particularly with increased risks related to specific types of strabismus.
  • Notably, offspring exposed to preeclampsia displayed an even higher risk, reinforcing the potential impact of maternal health on children's ocular health.
