Preoperative prediction of the selection of the NOTES approach for patients with symptomatic simple renal cysts via an interpretable machine learning model: a retrospective study of 264 patients.

Background: There are multiple surgical approaches for treating symptomatic simple renal cysts (SSRCs). The natural orifice transluminal endoscopic surgery (NOTES) approach has gradually been applied as an emerging minimally invasive approach for the treatment of SSRCs. However, there are no clear indicators for selecting the NOTES approach for patients with SSRCs.

A nested case-control study on the effect of sarcopenia on mild cognitive impairment using the CHARLS database.

Objective: This study aimed to assess the influence of sarcopenia on mild cognitive impairment (MCI) through a nationally representative survey.

Method: Participants in this nested case-control study were from the China Health and Retirement Longitudinal Study (CHARLS) cohort. In 2015, 3222 participants were included, with 2304 participants were followed up in 2018.

Biparametric MRI-based radiomics for noninvastive discrimination of benign prostatic hyperplasia nodules (BPH) and prostate cancer nodules: a bio-centric retrospective cohort study.

To investigate the potential of an MRI-based radiomic model in distinguishing malignant prostate cancer (PCa) nodules from benign prostatic hyperplasia (BPH)-, as well as determining the incremental value of radiomic features to clinical variables, such as prostate-specific antigen (PSA) level and Prostate Imaging Reporting and Data System (PI-RADS) score. A restrospective analysis was performed on a total of 251 patients (training cohort, n = 119; internal validation cohort, n = 52; and external validation cohort, n = 80) with prostatic nodules who underwent biparametric MRI at two hospitals between January 2018 and December 2020. A total of 1130 radiomic features were extracted from each MRI sequence, including shape-based features, gray-level histogram-based features, texture features, and wavelet features.

Basic Science and Pathogenesis.

Background: Changes in neuroinflammatory tone have been shown to modulate neuroimmune responses to Alzheimer's disease (AD) pathology and shape disease outcomes, however, extrinsic factors that modify neuroimmune activation remain poorly understood. The gut microbiome is one such factor, with the ability to shape peripheral and central immune activation, as well as AD pathologies. AD patients display unique changes in microbiome composition, however, the link between specific AD-associated gut bacteria, neuroinflammatory tone, and AD outcomes remains to be elucidated.

Effect of stearic acid and sodium stearate on hydrophobicity of nano calcium carbonate and mechanism of water vapor adsorption.

It is essential to understand the modification mechanism of hydrophobicity nano-CaCO to their potential application in different fields of chemistry. However, the water absorption of hydrophobicity nano-CaCO is seldom studied. In this study, Raman, BET and TGA experiments were performed on nano-CaCO samples to obtain surfactants contents and microstructure characteristics.
