Deep learning-based lymph node metastasis status predicts prognosis from muscle-invasive bladder cancer histopathology.

Purpose: To develop a deep learning (DL) model based on primary tumor tissue to predict the lymph node metastasis (LNM) status of muscle invasive bladder cancer (MIBC), while validating the prognostic value of the predicted aiN score in MIBC patients.

Biomarkers.

Background: Existing biomarkers including cerebrospinal fluid and positron emission tomography for Alzheimer's disease (AD) diagnosis are relatively invasive and expensive. Application of exhaled breath collection and volatile organic compound (VOC) detection for AD diagnosis remains unclear.

Method: In this cross-sectional study, high-pressure photon ionization time-of-flight mass spectrometry (HPPI-ToF-MS) was used to detect VOCs from breath in three datasets and patients diagnosed as Parkinson's disease (PD).

Biomarkers.

Background: Frontotemporal dementia (FTD) exhibits clinical phenotypic and genetic heterogeneity. However, reports on the clinical phenotypic characteristics and the frequency of genetic mutations in large-sample Chinese populations with FTD are lacking. Furthermore, the FTD diagnostic performance of plasma neurodegenerative biomarkers remains unclear.

Biomarkers.

Background: An objective and effective screening tool for cognitive impairment (CI) is needed in the Chinese population. However, whether the integration of brain resting-state functional connectivity (rs-FC) and neurodegenerative plasma biomarkers can distinguish CI from cognitively normal (CN) individuals remains unclear.

Method: A total of 1077 participants from a longitudinal Liuyang community cohort were enrolled.

A novel suture-free nephroplication with 4D-printed biodegradable bag for giant hydronephrosis: initial experience from hydromechanics and clinical application.

Background: Giant hydronephrosis as an rare condition is often caused by chronic ureteral obstruction. Nephroplication is a crucial procedure to improve urinary drainage in the kidney-sparing surgery for patients with giant hydronephrosis. However, traditional nephroplication via suturing kidney has technical difficulty and many potential risks.

Biomarkers.

Background: Aging exhibits significant variation among individuals, with biological age as a more reliable predictor of current health status compared to chronological age. Predicting biological age is crucial for facilitating timely interventions aimed at improving the adaptation to the aging process. Given the intricate and multifactorial nature of aging, a scientific approach involves constructing a prediction model for biological age that incorporates multiple dimensions systematically.
