Background: To identify the applicability of the Chinese Version of Mattis Dementia Rating Scale (DRS-CV).
Methods: The DRS-CV was administered to 483 participants, including 136 normal controls, 167 patients with mild cognition impairment (MCI), and 180 patients with Alzheimer's disease (AD). Receiver Operating Characteristic (ROC) curve was used to evaluate the sensitivity and specificity of the scale.
Results: The scores of DRS-CV were ranked in the order of NC > MCI > mild AD > moderate AD group. Memory was the sensitive function affected at a relatively earlier stage of AD. ROC curve analysis indicated the DRS-CV total score and memory subscale showed excellent sensitivity and specificity in the discrimination between MCI from mild AD and mild AD from moderate AD, but poor sensitivity and specificity in the discrimination between MCI and NC.
Conclusion: The DRS-CV is useful to the early diagnosis and severity of AD, not to the early identification of MCI.

Elevated serum uric acid (SUA) levels in pregnancy are linked to adverse outcomes, including preterm birth, preeclampsia, and low birth weight. To assess the predictive value of SUA levels in early pregnancy for adverse pregnancy outcomes (APOs). A cohort of 4,240 pregnant women admitted for delivery from January 2021 to December 2022 was analyzed.

Objectives: To assess the usefulness of sentinel lymph node biopsy (SLNB) in patients with early-stage oral squamous cell carcinoma (OSCC).
Materials And Methods: Seventy-five patients (mean age 62 years) diagnosed with cT1-2 N0 underwent SLNB with Tc, lymphoscintigraphy/SPECT-CT, and gamma probe detection with intraoperative histological examination of the resected sentinel lymph nodes (SLNs). Elective neck dissection was performed during the same surgical procedure of primary tumor resection when malignant deposits were detected microscopically.
Comprehensive Non-invasive Versus Invasive Approach to Evaluate Cardiac Allograft Vasculopathy in Heart Transplantation: The CCTA-HTx Study.
Circ Cardiovasc Imaging

Cardiovascular Center Aalst, Onze-Lieve-Vrouwziekenhuis (OLV) Clinic, Aalst, Belgium (M. Belmonte, P.P., M.M.V., M. Beles, H.O., R.S., G.E., M.S., R.D., W.H., J.V.K., J.B., M.V.).
Background: Coronary computed tomography angiography (CCTA) is emerging as a valuable tool for noninvasive surveillance of cardiac allograft vasculopathy (CAV) in patients with heart transplant (HTx). We assessed the diagnostic performance of a comprehensive CCTA-based approach compared with the invasive reference, which includes invasive coronary angiography, intravascular ultrasound, and fractional flow reserve, for detecting CAV.
Methods: This was a multicenter prospective study including 37 patients with HTx who underwent CCTA, invasive coronary angiography, intravascular ultrasound, and fractional flow reserve.

Background: Evaluate the clinical significance of esophagogastric junction (EGJ) morphology and esophagogastric junction contractile integral (EGJ-CI) in refractory gastroesophageal reflux disease (RGERD) patients.
Methods: From June 2021 to June 2023, 144 RGERD patients underwent comprehensive evaluation, recording symptom scores, demographic data. GERD classification (NERD or RE, A-D) was based on endoscopic findings.
Triglyceride-glucose index as a biomarker to differentiate stroke etiologic subtypes: a hospital-based cross-sectional study.
Biomark Med
January 2025
Neurology Department, University Hospital Fattouma Bourguiba, Monastir, Tunisia.
Background: Accurate distinction between stroke etiologic subtypes is critical for physicians to provide tailored treatment. The triglyceride-glucose (TyG) index, a marker of insulin resistance, has been associated with stroke risk but its role in distinguishing stroke etiologic subtypes remains unclear. We aimed to assess the TyG index's ability to differentiate cardioembolic (CE) from non-cardioembolic (NCE) strokes.
