Background: Preoperative differentiation of glioblastoma multiforme (GBM) and solitary brain metastasis (SBM) contributes to guide neurosurgical decision-making.
Purpose: To explore the value of histogram analysis based on neurite orientation dispersion and density imaging (NODDI) in differentiating between GBM and SBM and comparison of the diagnostic performance of two region of interest (ROI) placements.
Study Type: Retrospective.
Population: In all, 109 patients with GBM (n = 57) or SBM (n = 52) were enrolled.
Field Strength/sequence: A 3.0 T scanners. T -dark-fluid sequence, contrast-enhanced T magnetization-prepared rapid gradient echo sequence, and NODDI.
Assessment: ROIs were placed on the peritumoral edema area (ROI1) and whole tumor area (ROI2, included the cystic, necrotic, and hemorrhagic areas). Histogram parameters of each isotropic volume fraction (ISOVF), intracellular volume fraction (ICVF), and orientation dispersion index (ODI) from NODDI images for two ROIs were calculated, respectively.
Statistical Tests: Mann-Whitney U test, independent t-test, chi-square test, multivariate logistic regression analysis, DeLong's test.
Results: For the ROI1 and ROI2, the ICVF and ODI obtained the highest area under curve (AUC, AUC = 0.741 and 0.750, respectively) compared to other single parameters, and the AUC of the multivariate logistic regression model was 0.851 and 0.942, respectively. DeLong's test revealed significant difference in diagnostic performance between optimal single parameter and multivariate logistic regression model within the same ROI, and the multivariate logistic regression models between two different ROIs.
Data Conclusion: The performance of multivariate logistic regression model is superior to optimal single parameter in both ROIs based on NODDI histogram analysis to distinguish SBM from GBM, and the ROI placed on the whole tumor area exhibited better diagnostic performance.

The most significant progress in addressing the HIV/AIDS epidemic has been the development of antiretroviral therapy (ART). However, ensuring a high degree of treatment adherence is necessary to prevent resistance and disease progression. We conducted a cross-sectional study to evaluate adherence to ART through the calculation of the medication possession ratio (MPR) and to identify risk factors for suboptimal adherence in a cohort of HIV-positive patients receiving care at a Colombian healthcare institution across 16 cities.

Purpose: To examine the association between blastocyst morphology and chromosomal status utilizing pre-implantation genetic testing for aneuploidy (PGT-A).
Methods: A single-center retrospective cohort study including 169 in-vitro fertilization cycles that underwent PGT-A using Next Generation Sequencing (2017-2022). Blastocysts were morphologically scored based on Gardner and Schoolcraft's criteria.

Background: Alcohol-associated hepatitis (AH) leads to high rates of mortality and health care costs. Understanding the immediate costs after an AH diagnosis and identifying key cost factors is crucial for health care policies and clinical decisions.
Objectives: This study quantifies medical costs within 30 days of an AH diagnosis across outpatient (OP), emergency department (ED), and inpatient (IP) settings.

Hemolysis, elevated liver enzymes, low platelet count (HELLP) syndrome is a severe complication of preeclampsia (PE), with a higher incidence rate in people living at high altitudes, such as Tibet area. Maternal HELLP syndrome is associated with an elevated neonatal mortality rate. The purpose of this study was to investigate the predicting factors for neonatal outcomes with maternal HELLP syndrome.

This study aimed to investigate the correlation of the increased volume index of epicardial adipose tissue (EAT) and left ventricular hypertrophy (LVH) in patients with Hypertension (HTN). A total of 209 HTN patients and 50 healthy controls, who underwent cardiovascular magnetic resonance (CMR) at two medical centers in China between June 2015 and October 2024, were enrolled for this study. Postprocessing and imaging analysis were conducted and EAT measurements were performed.
