Objective: The purpose of this study was to compare the cost-effectiveness of combined first-trimester screening for fetal Down syndrome with second-trimester maternal serum triple screening.
Study Design: A first-trimester screening approach that used nuchal translucency measurement and maternal serum screening was evaluated against second-trimester maternal serum triple screening in a hypothetic population. Screening sensitivities and screen-positive rates were 91% and 5% for the first-trimester approach and 70% and 7.5% for the second-trimester approach, respectively. The costs of fetal Down syndrome, live-born Down syndrome cost, and total costs (screening plus live-born costs) were calculated for each screening program.
Results: First-trimester screening was associated with lower screening and live-born Down syndrome costs versus second-trimester serum screening. Total Down syndrome screening costs were 29.1% lower with first-trimester screening.
Conclusion: In this hypothetic model, combined first-trimester screening for fetal Down syndrome was more cost-effective than universal second-trimester triple serum screening.

Objective: Immune-related pancytopenia (IRP) is characterized by autoantibody-mediated destruction or suppression of bone marrow cells, leading to pancytopenia. This study aimed to explore the role of TRAPPC4 (trafficking protein particle complex subunit 4) as a key autoantigen in IRP, including epitope identification and immune activation mechanisms.
Methods: A total of 90 participants were included in the study, divided into four groups: 30 newly diagnosed IRP patients, 25 IRP remission patients, 20 patients with control hematologic conditions (severe aplastic anemia [SAA] and myelodysplastic syndrome [MDS]), and 15 healthy controls.

Purpose: While strategies aimed at preventing urological injuries complicating hysterectomy for gynaecological indications and placenta accreta surgery have been proposed, a comprehensive model for pregnancy-related hysterectomy (PRH) is lacking. The aim of this study was to investigate risk factors for urological complications of obstetric hysterectomy, and to propose strategies to improve the quality of care.
Methods: This retrospective study of patients undergoing PRH was conducted in an academic centre between 2009 and 2022.
Evaluating the clinical utility of , and bronchoalveolar PCRs for the diagnosis of invasive pulmonary infections in patients with hematological malignancies.

Invasive pulmonary infections are a significant cause of morbidity and mortality in patients with hematological malignancies and hematopoietic stem cell transplantation (HCT) recipients. A delay in identifying a causative agent may result in late initiation of appropriate treatment and adverse clinical outcomes. We examine the diagnostic utility of PCR-based assays in evaluating invasive pulmonary infections from bronchoalveolar lavage (BAL).

Unlabelled: Hepatitis E virus (HEV) is a globally prevalent zoonotic pathogen that is primarily spread through the fecal-oral route, such as by consuming undercooked or contaminated pork. HEV infection leads to an estimated 3.3 million symptomatic cases of viral hepatitis and 70,000 deaths in human populations each year.

Objectives: Hypertriglyceridemia-associated acute pancreatitis (HTG-AP) is one of the most common etiologies of acute pancreatitis (AP) worldwide. Compared to other etiologies, patients with HTG-AP may develop more severe AP, but previous studies yielded controversial conclusion due to the lack of adequate adjustment for the confounders. Therefore, this study aimed to examine the possibility and risk factors of developing severe AP in HTG-AP.
