Predictive Study of Machine Learning-Based Multiparametric MRI Radiomics Nomogram for Perineural Invasion in Rectal Cancer: A Pilot Study.

This study aimed to establish and validate the efficacy of a nomogram model, synthesized through the integration of multi-parametric magnetic resonance radiomics and clinical risk factors, for forecasting perineural invasion in rectal cancer. We retrospectively collected data from 108 patients with pathologically confirmed rectal adenocarcinoma who underwent preoperative multiparametric MRI at the First Affiliated Hospital of Bengbu Medical College between April 2019 and August 2023. This dataset was subsequently divided into training and validation sets following a ratio of 7:3.

Body Mass Index z Scores Correlate with Epidermal Function in Chinese Children.

Background/objective: Epidermal function is altered in a number of cutaneous and extracutaneous disorders. To determine whether epidermal function is also altered in children with obesity, we assessed the correlation between the body mass index (BMI) z score and epidermal function in children.

Participants And Methods: Participants were enrolled from outpatient clinic, schools and kindergartens.

Trend of changes in epidermal biophysical properties in the Chinese aged 1 month to 17-year old.

Background: Although it is known that epidermal biophysical properties vary with age and gender, the changes in epidermal biophysical properties over the time from baby to adolescence have not been elucidated yet. In the present study, we assessed the trend of changes in transepidermal water loss rates (TEWL), stratum corneum hydration, and skin surface pH in Chinese children.

Participants And Methods: A total of 780 boys and 610 girls, aged 1 month to 17-year old, were enrolled in this study.

Resting Cardiac Power Predicts Adverse Outcome in Heart Failure Patients With Preserved Ejection Fraction: A Prospective Study.

Background: We sought to explore the significance of resting cardiac power/mass in predicting adverse outcome in patients with heart failure with preserved ejection fraction (HFpEF).

Methods: This prospective cohort study included patients with HFpEF and without significant valve disease or right ventricular dysfunction. Cardiac power was normalized to left ventricular (LV) mass and expressed in W/100 g of LV myocardium.

The value of whole-brain CT perfusion imaging combined with dynamic CT angiography in the evaluation of pial collateral circulation with middle cerebral artery occlusion.

Background: Middle cerebral artery (MCA) occlusion is extremely common, especially unilateral artery, which can result in a significant incidence of cerebral infarction.

Objective: To assess the value of whole-brain computed tomography perfusion (CTP) imaging combined with dynamic CT angiography (dCTA) in the evaluation of pial collateral circulation in patients with MCA occlusion.

Methods: Whole-brain CTP and dCTA images were acquired in 58 patients with unilateral MCA occlusion.

Application of intravoxel incoherent motion diffusion-weighted imaging in differential diagnosis and molecular subtype analysis of breast cancer.

Objective: To explore the application of incoherent motion diffusion-weighted imaging (IVIM-DWI) in the differential diagnosis and molecular subtype analysis of breast cancer.

Methods: The clinical data of 225 patients with breast masses were selected, including breast cancers (n = 135) and benign breast tumors (n = 90). According to pathological results, breast cancers were divided into four subtypes: Luminal A (n = 24), Luminal B (n = 57), HER-2-overexpression (n = 27) and triple-negative breast cancers (n = 27).

Comparison of spectral computed tomography imaging parameters between squamous cell carcinoma and adenocarcinoma at the gastroesophageal junction.

Objective: To compare the spectral computed tomography (CT) imaging parameters between squamous cell carcinoma (SCC) and adenocarcinoma (AC) at the gastroesophageal junction (GEJ).

Methods: A total of 80 patients were enrolled in this retrospective study. Among them, 35 were diagnosed with SCC (SCC group) and 45 were diagnosed with AC (AC group).
