Background: Preterm brain injury (PBI) is a prevalent complication in preterm infants, leading to the destruction of critical structural and functional brain connections and placing a significant burden on families. The timely detection of PBI is of paramount importance for the prevention and treatment of the condition. However, the absence of specific clinical manifestations in the early stages of PBI renders it susceptible to misdiagnosis and missed diagnoses.

Background: The current congenital heart disease (CHD) prediction tools lack adequate interpretability and convenience, hindering the development of personalized CHD management strategies. We developed a machine learning-based risk stratification model for CHD prediction.

Methods: This study utilized data from 1,759 participants in a case-control study of CHD conducted across six birth defects surveillance hospitals located in Xi'an, Shaanxi Province, Northwest China, spanning from January 2014 to December 2016.

Article Synopsis
  • The study explores dry reforming of methane (DRM) using CeO(111)-supported transition metal clusters, particularly focusing on metals like Ru, Pt, Co, and Ni through density functional theory (DFT) and microkinetic modeling.
  • *DFT calculations reveal that Ru and Co have strong oxygen adsorption abilities, making them effective for CO activation, with Ru/CeO(111) showing the highest efficiency for activating both CH and CO.
  • *Microkinetic simulations rank the activity of the catalysts, showing Ru/CeO(111) as the most active, while Pt/CeO(111) excels in anticoking, and Co/CeO and Ni/CeO exhibit lower stability and activity.*

Article Synopsis
  • Inflammatory bowel disease (IBD) poses a significant health risk, including an increased chance of developing colorectal cancer (CRC), but understanding and treatment options are still limited.
  • This study identifies FBXO22, a protein that helps regulate cellular processes, as a key player in inhibiting inflammation and CRC by promoting the degradation of a specific form of mTOR, which is involved in cancer signaling.
  • Treatment with the mTOR inhibitor rapamycin shows promise in reducing colorectal inflammation and cancer effects, highlighting the potential role of FBXO22 and mTOR pathways in colorectal disease management.

: To examine the effects of peripheral blood eosinophil (EOS) count and its dynamic alterations on the treatment efficacy and prognosis of patients with advanced hepatitis B virus-associated hepatocellular carcinoma (HBV-HCC) receiving camrelizumab combined with lenvatinib (C + L) therapy. : A retrospective analysis was performed on 200 patients with advanced HBV-HCC who were admitted to two centers from January 2018 to August 2023 and treated with C + L. EOS, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) were determined before C + L treatment (EOS0, NLR0, and PLR0) and after three cycles of treatment (EOS3, NLR3, and PLR3).

Mine flooding accidents have occurred frequently in recent years, and the predicting of mine water inflow is one of the most crucial flood warning indicators. Further, the mine water inflow is characterized by non-linearity and instability, making it difficult to predict. Accordingly, we propose a time series prediction model based on the fusion of the Transformer algorithm, which relies on self-attention, and the LSTM algorithm, which captures long-term dependencies.

Article Synopsis
  • Bilateral ductus arteriosus (BDA) is a rare vascular malformation, formed when the sixth pairs of primitive arches don't regress, leading to abnormal blood vessel connections, as seen in a specific fetal case.
  • The case involved a 22-year-old pregnant woman who underwent an echocardiogram at 23 weeks, revealing multiple heart defects, including right aortic arch mirror-image branching and a vascular ring formed by the BDA.
  • The study summarizes previous cases of BDA and emphasizes that this particular case showcases a unique combination of intracardiac structural problems and vascular anomalies, prompting the mother to choose termination of the pregnancy after consultations.

Background And Aims: This meta-analysis was performed to compare the efficacy and safety of a triple therapy, involving transcatheter arterial chemoembolization (TACE) + apatinib combined with a programmed-cell death protein-1 (PD-1) inhibitor versus TACE + apatinib, a dual therapy with apatinib and PD-1 inhibitor, and TACE alone for the treatment of advanced primary hepatocellular carcinoma (HCC).

Methods: A computerized systematic search of databases, such as PubMed, Embase, the Cochrane Library, CNKI, Wanfang Data, and VIP e-Journals was performed to retrieve studies comparing TACE + apatinib combined with a PD-1 inhibitor versus a non-triple therapy for the treatment of advanced primary HCC. The literature search, quality assessment, and data extraction were performed independently by two researchers.

Advanced hepatocellular carcinoma (HCC) is a severe malignancy that poses a serious threat to human health. Owing to challenges in early diagnosis, most patients lose the opportunity for radical treatment when diagnosed. Nonetheless, recent advancements in cancer immunotherapy provide new directions for the treatment of HCC.

Introduction: Although it is well-known that obesity increases the risk of gestational hypertension (GH) in both spontaneous and assisted reproductive technology (ART) pregnancies. Recent data show that, in ART pregnancies, frozen-thawed embryo transfer (FET) is associated with an even higher risk of GH compared with fresh transfer. However, the relationship between pre-gravid body mass index (BMI) and GH in FET pregnancies has seldom been reported.

Objective: To evaluate whether we can identify patient characteristics that serve as treatment selection markers to distinguish which women with expected poor response benefit from increased dosing of follicle-stimulating hormone (FSH) in terms of improving the cumulative live birth rate compared to standard FSH dosing and which women.

Study Design: We performed a secondary analysis of an RCT performed between March 2019 and October 2021 comparing cumulative live birth after increased dosing (N = 328) who received 225 or 300 IU/day according to their antral follicle count (AFC) and standard dosing (N = 333) who received 150 IU/day of gonadotropin.

Results: The MFPI analysis showed the benefit of the increased dosing of FSH on cumulative live birth starts to emerge when women were older than 30 years (women > 30 years: 46.

Article Synopsis
  • In frozen-thawed embryo transfer (FET) cycles, hormone replacement treatment (HRT) is linked to a higher risk of hypertensive disorders of pregnancy (HDP) compared to natural cycles (NC), particularly in singleton pregnancies.
  • A study involving 9,120 women found that HRT-FET resulted in a 6.21% risk of HDP in singleton pregnancies, significantly higher than the 4.09% in NC-FET after adjustments for age and BMI.
  • However, in multiple pregnancies, the risk of HDP was similar between the HRT-FET and NC-FET groups, suggesting HRT's elevated risk primarily affects singleton pregnancies.
