Radiomics and deep learning for large volume lymph node metastasis in papillary thyroid carcinoma.

Background: Thyroid cancer is prone to early lymph node metastasis (LNM), and patients with large volume LNM (LVLNM) tend to have a poorer prognosis. The aim of this study was to predict LVLNM in before surgery based on radiomics and deep learning (DL).

Methods: A multicenter retrospective study was performed, including 854 papillary thyroid carcinoma (PTC) patients from three centers.

De-escalating chemotherapy for stage I-II gastric neuroendocrine carcinoma? A real-world competing risk analysis.

Background: The role of adjuvant chemotherapy in gastric neuroendocrine neoplasms (GNEC) has not been well clarified yet. The study was designed to investigate the potential effect of adjuvant chemotherapy in stage I-II GNEC patients and construct a predictive nomogram.

Method: Stage I-II GNEC patients were included in the Surveillance, Epidemiology, and End Results (SEER) database and divided into chemotherapy and no-chemotherapy groups.

Identification of cuproptosis-related lncRNAs to predict prognosis and immune infiltration characteristics in alimentary tract malignancies.

Background: Alimentary tract malignancies (ATM) caused nearly one-third of all tumor-related death. Cuproptosis is a newly identified cell death pattern. The role of cuproptosis-associated lncRNAs in ATM is unknown.

Ultrasound-Based Risk Stratification System for the Assessment of Partially Cystic Thyroid Nodules.

Objective: To develop and validate a risk stratification system for the prediction of malignancy in partially cystic thyroid nodules (PCTNs).

Methods: We retrospectively reviewed the sonography data of patients with PCTNs from 2 medical centers-Hangzhou Traditional Chinese Medicine Hospital and Hangzhou First People's Hospital-from January 2020 to December 2021. The independent risk factors for malignant PCTNs were evaluated using the univariate and multivariate logistic regression analyses.

A novel nomogram for identifying candidates for adjuvant chemotherapy in patients with stage IB gastric adenocarcinoma.

Background: The purpose of this research was to construct a novel predictive nomogram to identify specific stage IB gastric adenocarcinoma (GAC) populations who could benefit from postoperative adjuvant chemotherapy (ACT).

Method: Between 2004 and 2015, 1889 stage IB GAC patients were extracted from the Surveillance, Epidemiology, and End Results (SEER) program database. Then Kaplan-Meier survival analysis, univariate and multivariable Cox analyses, and univariate and multivariable logistic analyses were implemented.

Application of Intraoperative Fluorescence Imaging with Indocyanine Green in the Difficult Gallbladder: A Comparative Study between Indocyanine Green-Guided Fluorescence Cholangiography and Conventional Surgery.

In the difficult gallbladder, the rate of bile duct injury (BDI) remains high. To lessen iatrogenic biliary injury, we attempted to utilize indocyanine green (ICG)-guided fluorescence cholangiography during surgery to illuminate the extrahepatic biliary tract. According to admission criteria, 38 patients were diagnosed with difficult gallbladder and underwent percutaneous transhepatic gallbladder drainage (PTGBD).

The role of chemotherapy in patients with stage IB gastric adenocarcinoma: a real-world competing risk analysis.

Background: This study aimed to investigate the potential effect of adjuvant chemotherapy in patients diagnosed with stage IB gastric adenocarcinoma (GAC).

Method: A total of 1727 patients were included in the Surveillance, Epidemiology, and End Results (SEER) database from 2004 to 2015 and divided into the chemotherapy and no-chemotherapy groups. Then, the methods of Kaplan-Meier analysis, propensity score matching (PSM), and competing risk analysis were implemented.

Anatomic Subsites and Prognosis of Gastric Signet Ring Cell Carcinoma: A SEER Population-Based 1 : 1 Propensity-Matched Study.

Background: The dismal prognosis of gastric signet ring cell carcinoma (GSRC) is a global problem. The current study is conducted to comprehensively evaluate clinicopathological features and survival outcomes in GSRC patients stratified by anatomic subsites. Then, predictive nomograms are constructed and validated to improve the effectiveness of personalized management.

Nano-biological mesh constructed by astragaloside-IV-induced bone marrow mesenchymal stem cells on PLGA-NPs-SIS can be used for abdominal wall reconstruction.

A combination of stem cells, scaffold materials, nanoparticles (NPs), and physiological factors can be used to engineer a tissue that can replace or improve the function of the damaged tissue. This study was designed to assess whether astragaloside (aS)-IV-activated rat bonemarrow-derived mesenchymal stem cells (BMSCs), seeded on a nano-biological mesh composed of small intestinal submucosa (SIS) modified with poly (D,L-lactide-co-glycolide) NPs (PLGA-NPs-SIS), can promote cell engraftment, proliferation, and mesh incorporation into the tissue upon implantation. aS-IV-induced BMSCs cultured with PLGA-NPs-SIS showed enhanced viability and proliferation as well as reduced apoptosis.

Precision Liver Resection: Three-Dimensional Reconstruction Combined with Fluorescence Laparoscopic Imaging.

Liver surgery has entered the era of precision surgery. Therefore, how to optimize the resection of lesions and reduce the unnecessary time of liver ischemia and hypoxia have become the focus. A total of 11 patients who underwent fluorescence laparoscopic liver mass resection and preoperative three-dimensional (3D) reconstruction between August 2018 and July 2020 were evaluated.

Combination of Electronic Choledochoscopy and Holmium Laser Lithotripsy for Complicated Biliary Calculus Treatment: A New Exploration.

The safety and efficacy of the combination of electronic choledochoscopy and holmium laser lithotripsy for complicated bile duct stones were assessed. In total, 20 patients participated in this study, which was conducted between 2012 and 2017. None of the patients were candidates for endoscopic retrograde cholangiopancreatography with stone extraction.
