Comparing customized ChatGPT and pathology residents in histopathologic description and diagnosis of common diseases.

This study aimed to evaluate and analyze the performance of a customized Chat Generative Pre-Trained Transformer (ChatGPT), known as GPT, against pathology residents in providing microscopic descriptions and diagnosing diseases from histopathological images. A dataset of representative photomicrographs from 70 diseases across 14 organ systems was analyzed by a customized version of ChatGPT-4 (GPT-4) and pathology residents. Two pathologists independently evaluated the microscopic descriptions and diagnoses using a predefined scoring system (0-4 for microscopic descriptions and 0-2 for pathological diagnoses), with higher scores indicating greater accuracy.

The effectiveness of using dye models for small tissue biopsies in the surgical pathology laboratory.

Introduction: Losing of small tissues during tissue preparatory steps may seriously affect pathological diagnostic performance. Using an appropriate tissue marking dye could be an alternative solution. Therefore, the aim of the study was to find a suitable tissue marking dye to enhance the observable ability of various types of small-size tissues during several steps of tissue preparation.

Effectiveness of the Air-Filled Technique to Reduce the Dead Space in Syringes and Needles during ChAdox1-n CoV Vaccine Administration.

In the current study, we calculated the vaccine volume and amount of dead space in a syringe and needle during ChAdox1-n CoV vaccine administration using the air-filled technique. The aim is to reduce the dead space in syringes and needles in order to administer up to 12 doses per vial. The hypothetical situation uses a vial with a similar size as the ChAdox1-n CoV vial.

Cranial versus Caudal Direction Technique of Native Percutaneous Kidney Biopsy: A Randomized Controlled Trial.

Background: Percutaneous kidney biopsy (PKB) is the gold standard for diagnosing various kidney diseases, but it can result in potential complications. This study aimed to compare kidney tissue adequacy and safety between the two biopsy techniques, including cranial direction (CN) and caudal direction (CD), of needle biopsy under real-time ultrasonogram guidance.

Methods: This single-center, prospective, single-blinded, randomized trial included patients undergoing native PKB from July 5, 2017, to June 30, 2019.

Interobserver variability in inconclusive diagnostic categories of thyroid fine needle aspiration cytology: An urban-based tertiary hospital experience.

Introduction: Thyroid nodules are typical lesions, usually non-malignant, and surgery is unnecessary in most patients. However, distinguishing between benign and malignant is challenging. Fine needle aspiration cytology (FNAC) is considered a primary diagnostic and prognostic tool with an effective cost for evaluating thyroid enlargement.

Notch signaling regulates vasculogenic mimicry and promotes cell morphogenesis and the epithelial-to-mesenchymal transition in pancreatic ductal adenocarcinoma.

Vasculogenic mimicry (VM) is the process where cancer cells adopt endothelial characteristics by forming tube-like structures and perfusing channels. This phenomenon has been demonstrated in several types of solid tumors and associated with the growth and survival of tumor cells. In this study, we investigated the presence of VM formation in human pancreatic ductal adenocarcinoma (PDAC) and elucidated the molecular mechanisms underlying the VM process.

Correlation of vascular structural changes in a cadaveric model and obesity-related cardiovascular non-communicable diseases.

Introduction: Carrying excess body weight is a vital risk factor for obesity-related chronic diseases affecting blood vessels. Obesity influences cardiovascular non-communicable diseases (NCDs) via vascular structural changes, which involve alterations in lipids, blood pressure, coagulation, fibrinolysis, and inflammation, leading to endothelial dysfunction due to vascular remodeling and stiffness. Small peripheral vessels are the first to be impacted; however, it is unclear whether this change is followed by microscopic changes in the aorta.
