Interpretable machine learning models for predicting skip metastasis in cN0 papillary thyroid cancer based on clinicopathological and elastography radiomics features.

Departments of Ultrasound, Jiading District Central Hospital Affiliated Shanghai University of Medicine &Health Sciences, Shanghai, China.
Background: Skip lymph node metastasis (SLNM) in papillary thyroid cancer (PTC) involves cancer cells bypassing central nodes to directly metastasize to lateral nodes, often undetected by standard preoperative ultrasonography. Although multiple models exist to identify SLNM, they are inadequate for clinically node-negative (cN0) patients, resulting in underestimated metastatic risks and compromised treatment effectiveness. Our study aims to develop and validate a machine learning (ML) model that combines elastography radiomics with clinicopathological data to predict pre-surgical SLNM risk in cN0 PTC patients with increased risk of lymph node metastasis (LNM), improving their treatment strategies.

Background: Clinical determination of patients at high risk of poor surgical outcomes is complex and may be supported by clinical tools to summarize the patient's own personalized electronic health record (EHR) history and vitals data through predictive risk models. Since prior models were not readily available for EHR-integration, our objective was to develop and validate a risk stratification tool, named the Assessment of Geriatric Emergency Surgery (AGES) score, predicting risk of 30-day major postoperative complications in geriatric patients under consideration for urgent and emergency surgery using pre-surgical existing electronic health record (EHR) data.
Methods: Patients 65-years and older undergoing urgent or emergency non-cardiac surgery within 21 hospitals 2017-2021 were used to develop the model (randomly split: 80% training, 20% test).
Pineal region tumors: prognostic stratification based on magnetic resonance imaging features-a retrospective cohort study.
Quant Imaging Med Surg
January 2025
Department of Radiology, Seventh Medical Center of Chinese PLA General Hospital, Beijing, China.
Background: Pineal region tumors encompass a wide range of pathologies, presenting challenges in pre-surgical characterization and exhibiting variable prognostic outcomes across different tumor types. This study aims to identify key imaging features from pre-treatment magnetic resonance imaging (MRI) of pineal region tumors to aid in prognostic analysis.
Methods: We retrospectively enrolled 33 patients with pineal region tumors who underwent pre-treatment imaging at the Seventh Medical Center of the Chinese PLA General Hospital between January 2010 and June 2023.
Prehabilitation for Chilean frail elderly people - pre-surgical conditioning protocol - to reduce the length of stay: randomized control trial.
Minerva Anestesiol
December 2024
Department of Anesthesiology, School of Medicine, Pontificia Universidad Católica de Chile, Santiago, Chile.
Background: Frail elderly patients have a higher risk of postoperative morbidity and mortality. Prehabilitation is a potential intervention for optimizing postoperative outcomes in frail patients. We studied the impact of a prehabilitation program on length of stay (LOS) in frail elderly patients undergoing elective surgery.

Introduction Degenerative spondylolisthesis (DS) is a degenerative condition characterized by subluxation of one vertebral body anterior to the adjacent inferior vertebral body with an intact pars. Conservative treatment approaches, such as steroid injections and physical therapy, may work well at first, but in resistant situations, surgery is frequently necessary. Posterolateral lumbar fusion (PLF) has been widely used, but transforaminal lumbar interbody fusion (TLIF) offers theoretical advantages such as improved alignment and enhanced fusion rates.
