Background: This study evaluates the efficacy of a nomogram for predicting the pathology upgrade of apical prostate cancer (PCa).
Methods: A total of 754 eligible patients were diagnosed with apical PCa through combined systematic and magnetic resonance imaging (MRI)-targeted prostate biopsy followed by radical prostatectomy (RP) were retrospectively identified from two hospitals (training: 754, internal validation: 182, internal-external validation: 148). A nomogram for the identification of apical tumors in high-risk pathology upgrades through comparing the results of biopsy and RP was established incorporating statistically significant risk factors based on univariable and multivariable logistic regression.
Background: This study seeks to assess the utility of T1 and T2 mapping in distinguishing metastatic lymph nodes from reactive lymphadenopathy in patients with head and neck squamous cell carcinoma (HNSCC), using diffusion-weighted imaging (DWI) as a comparison.
Methods: Between July 2017 and November 2019, 46 HNSCC patients underwent neck MRI inclusive of T1 and T2 mapping and DWI. Quantitative measurements derived from preoperative T1 and T2 mapping and DWI of metastatic and non-metastatic lymph nodes were compared using independent samples t-test or Mann-Whitney U test.
(1) Background: This study aims to evaluate the image quality of abnormal cervical lymph nodes in head and neck cancer and the diagnostic performance of detecting extranodal extension (ENE) using free-breathing StarVIBE. (2) Methods: In this retrospective analysis, 80 consecutive head and neck cancer patients underwent StarVIBE before neck dissection at an academic center. Image quality was compared with conventional VIBE available for 28 of these patients.

Methods: Patients with malignancy-associated membranous nephropathy in a tertiary hospital in China between June 2012 and October 2021 were retrospectively reviewed.
Results: Forty-two patients with malignancy-associated membranous nephropathy were identified.
Background: Intrahepatic cholangiocarcinoma (ICC) is a highly lethal hepatobiliary cancer, and very few patients can undergo surgery. The prognosis of advanced ICC is poor, especially in patients who progress after first-line chemotherapy, with a median overall survival of less than 10 months.
Case Presentation: A 64-year-old male was diagnosed with advanced intrahepatic cholangiocarcinoma with ERBB2 (HER2) 3 + amplification determined by tissue-based testing and confirmed by next-generation sequencing.
In situ generation of hydrogen peroxide (H O ) has attracted extensive attention, especially in water treatment. However, traditional anthraquinones can only produce high-concentration H O and its transportation and storage are not convenient and dangerous. Herein, an in situ and on-demand strategy to produce H O by using a cascade water electrolysis together with a heterocatalysis system is provided.

Furthermore, we compared their features before and after the period of immunotherapy for lung cancer. A retrospective analysis of the clinical characteristics of hospitalized LC patients with definite pathological diagnoses was performed from 2014 to 2021.

Previously, supports of a single atom consist of multiple elements, making C-C coupling difficult because the coordination environment of single-atom sites is diversified and difficult to control. Here, we steer C-C coupling by implanting an Au single atom on the red phosphorus (Au/RP), support with uniform structure composed of a single element, lower electronegativity, and better ability to absorb CO.

It has been estimated to account 4% of previously diagnosed PRN.
Case Presentation: This is a retrospective case report of two patients diagnosed with PRNRP.

Parathyroid carcinomas are difficult to distinguish from adenomas according to the current diagnostic criteria. The judgment of local infiltration is subjective and inconsistent. Existing studies have found that the CDC73 gene encoding parafibromin is related to the occurrence of parathyroid carcinomas.

Purpose: This study aimed to clarify the clinical features of and evaluate the treatment efficacy for IgG4-related thyroiditis.
Methods: Fourteen IgG4-related thyroiditis patients and 42 randomly matched IgG4-related disease (IgG4-RD) patients without thyroiditis in a prospective cohort at the Peking Union Medical College Hospital (PUMCH) were enrolled from 2011 to 2019. Patient demographics, clinical characteristics, laboratory parameters and treatment efficacy were analysed.
Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest cancer types worldwide, with the lowest 5-year survival rate among all kinds of cancers. Histopathology image analysis is considered a gold standard for PDAC detection and diagnosis. However, the manual diagnosis used in current clinical practice is a tedious and time-consuming task and diagnosis concordance can be low.

Automated image analysis served as an aided PD-L1 scoring tool for pathologists to reduce inter- and intrareader variability. We developed a novel automated tumor proportion scoring (TPS) algorithm, and evaluated the concordance of this image analysis algorithm with pathologist scores.

Here, we have reported two recently identified cases of immunocompetent PPL having diffuse large B-cell lymphoma by surgical biopsy. Both patients had hypopituitarism, with one patient developing right ptosis.
