To reveal the association between DNMT1 polymorphisms and congenital heart disease (CHD) in child patients, a total of 224 CHD child patients as well as 199 healthy individuals were enrolled in the present study. The DNA was extracted from whole blood, and four SNPs including rs16999593, rs2228612, rs2288349 and rs10420321 were selected for the gene polymorphism investigation via ligase detection reaction (LDR) assay. Odds ratios (ORs) and 95 % confidence intervals (95 % CIs) were used to assess the strength of the association. rs16999593 was associated with the CHD under the heterozygous (CT vs TT: OR 0.62; 95 % CI 0.41-0.95; p = 0.03), dominant (CT + CC vs TT: OR 0.63; 95 % CI 0.42-0.95; p = 0.03), and allele models (C vs T: OR 0.07; 95 % CI 0.50-1.00; p = 0.05). rs2228612 was related with the CHD under the heterozygous (AG vs AA: OR 0.42; 95 % CI 0.27-0.65; p = 0.0001), homozygous (GG vs AA: OR 0.43; 95 % CI 0.240-0.77; p = 0.004), dominant (AG + GG vs AA: OR 0.42; 95 % CI 0.28-0.64; p < 0.0001), and allele models (G vs A: OR 0.62; 95 % CI 0.47-0.82; p = 0.0007). rs10420321 correlated with the CHD only under the recessive model (GG vs AG + AA: OR 0.61; 95 % CI 0.37-1.01, p = 0.05). However, no significant association between the rs2288349 polymorphisms and the risk of CHD was observed (p > 0.05). DNMT1 polymorphisms might contribute to the risk of CHD, especially rs16999593 and rs2228612.

Background: Archetypes are representations of a group of people with shared behaviors, attitudes, and characteristics. The design and use of archetypes have potential application to increase partnership and support when embedding and scaling interventions but methodological approaches have not been developed.
Objective: To describe the methodology of designing archetypes for use in a pragmatic trial of advance care planning in the primary care context, SHARING Choices ((NCT04819191).

Background: The postpartum period provides an opportunity for birthing people with opioid use disorder (OUD) to consider their future reproductive health goals. However, the relationship between the use of medication for opioid use disorder (MOUD) and contraception utilization is not well understood. We used multistate administrative claims data to compare contraception utilization rates among postpartum people with OUD initiating buprenorphine (BUP) versus no medication (psychosocial services receipt without MOUD (PSY)) in the United States (US).

Recent genomic studies have allowed the subdivision of intracranial ependymomas into molecularly distinct groups with highly specific clinical features and outcomes. The majority of supratentorial ependymomas (ST-EPN) harbor ZFTA-RELA fusions which were designated, in general, as an intermediate risk tumor variant. However, molecular prognosticators within ST-EPN ZFTA-RELA have not been determined yet.

Background: Triglyceride-glucose (TyG) index was suggested as a possible surrogate for insulin resistance and a predictor for cardiovascular diseases and diabetes in the non-pregnant population. However, the relationship between TyG index in early pregnancy and adverse pregnancy outcomes (APOs), and the contribution of pre-pregnancy body mass index (BMI) was still illusive.
Methods: A large retrospective cohort study involving 67,936 pregnant Chinese women between 2017 and 2022 was conducted.

Background: We aimed to measure the effect of a 2-day structured paediatric simulation-based training (SBT) on basic and advanced airway management during simulated paediatric resuscitations.
Methods: Standardised paediatric high-fidelity SBT was conducted in 12 of the 15 children's hospitals in Hesse, Germany. Before and after the SBT the study participants took part in two study scenarios (PRE and POST scenario), which were recorded using an audio-video system.
