Objectives: Observational data on the impact of on-site cytopathology evaluation (OCE) during endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) of pancreatic masses have reported conflicting results. We aimed to compare the diagnostic yield of malignancy and proportion of inadequate specimens between patients undergoing EUS-FNA of pancreatic masses with and without OCE.

Methods: In this multicenter randomized controlled trial, consecutive patients with solid pancreatic mass underwent randomization for EUS-FNA with or without OCE. The number of FNA passes in the OCE+ arm was dictated by the on-site cytopathologist, whereas seven passes were performed in OCE- arm. EUS-FNA protocol was standardized, and slides were reviewed by cytopathologists using standardized criteria for cytologic characteristics and diagnosis.

Results: A total of 241 patients (121 OCE+, 120 OCE-) were included. There was no difference between the two groups in diagnostic yield of malignancy (OCE+ 75.2% vs. OCE- 71.6%, P=0.45) and proportion of inadequate specimens (9.8 vs. 13.3%, P=0.31). Procedures in OCE+ group required fewer EUS-FNA passes (median, OCE+ 4 vs. OCE- 7, P<0.0001). There was no significant difference between the two groups with regard to overall procedure time, adverse events, number of repeat procedures, costs (based on baseline cost-minimization analysis), and accuracy (using predefined criteria for final diagnosis of malignancy). There was no difference between the two groups with respect to cytologic characteristics of cellularity, bloodiness, number of cells/slide, and contamination.

Conclusions: Results of this study demonstrated no significant difference in the diagnostic yield of malignancy, proportion of inadequate specimens, and accuracy in patients with pancreatic mass undergoing EUS-FNA with or without OCE.

Background: Obstructive jaundice is a common health challenge in daily clinical practice caused by a heterogeneous group of benign and malignant conditions in or around extrahepatic bile ducts. This study aimed to investigate the causes of obstructive jaundice, analyze the age and sex distribution, and report the locations of obstruction.

Methods: This was a retrospective study of electronic records of patients diagnosed with obstructive jaundice in the Hadhramout region in Yemen.

Pancreatic masses pose a diagnostic difficulty due to the technical complexities related to tissue acquisition. Endoscopic ultrasound (EUS)-guided tissue acquisition has transformed the field by allowing access to pancreatic lesions through fine-needle and biopsy. However, diagnostic accuracy differs based on tumor characteristics and procedural factors.

Aims: Semaglutide, a novel long-acting GLP-1RA, stimulates insulin and suppresses islet-secreted glucagon to reduce glucose levels. It has been unveiled that m6A mRNA modification plays a pivotal role in regulating β cell function. However, it remains unclear whether semaglutide can elicit protective effects through manipulating m6A modification and the underlying mechanism.

Introduction: Nonbacterial thrombotic endocarditis (NBTE) is a rare cardiac manifestation in patients with advanced malignancies of the lungs, pancreas, gynecological system, and gastrointestinal tract. It is often confirmed postmortem by histopathological evidence of sterile platelet-fibrin deposits attached to the endocardium, most often on heart valves. To the best of our knowledge, our case is the first to report multiple heart lesions caused by the systemic effect of cholangiocarcinoma.

Purpose: The main objectives were to study differences between the first and the fourth cycle in dosimetry variables in patients treated for neuroendocrine tumours with four cycles of [Lu]Lu-DOTA-TATE, as well as to look for absorbed dose-effect correlations aiming to help individualise and optimise this therapy for future patients.

Material And Methods: SPECT based dosimetry of tumour lesions and kidneys was performed in the first and the fourth cycles of the [Lu]Lu-DOTA-TATE treatments for 17 patients from 2020 to 2023. Clinical variables of interest were collected in order to look for correlations with some dosimetry variables.
