222 electric polypectomies were performed in the course of fibrocolonoscopy carried out in 114 patients. The results of examination of 172 removed neoplasms testified to the high effectiveness of the procedure in identifying the morphological structure of colonic polyps. Due to application of endoscopic polypectomy, which is essentially a total biopsy, histological diagnosis obtained on the basis of aiming biopsy was improved or modified in 67% of cases. However, aiming biopsy should be used because more than 20% of resected polyps fail to be removed from colonic lumen.

Background: Next-generation sequencing (NGS) for Hepatitis B virus (HBV) antiviral resistance (AVR) testing is a highly sensitive diagnostic method, able to detect low-level mutant subpopulations. Our clinical virology laboratory previously transitioned from DNA hybridization (INNO-LiPA) to NGS, initially with the GS Junior System and subsequently the MiSeq. The Oxford Nanopore Technology (ONT) sequencing system was evaluated for HBV resistance testing, with regards to sequencing accuracy and turn-around time.

February 2025
Liver Research Center, Beijing Friendship Hospital, Capital Medical University, Beijing, China.
Background And Aim: Discriminating between idiosyncratic drug-induced liver injury (DILI) and autoimmune hepatitis (AIH) is critical yet challenging. We aim to develop and validate a machine learning (ML)-based model to aid in this differentiation.
Methods: This multicenter cohort study utilised a development set from Beijing Friendship Hospital, with retrospective and prospective validation sets from 10 tertiary hospitals across various regions of China spanning January 2009 to May 2023.
Oral and Maxillofacial Manifestations of Kallmann Syndrome: A Systematic Analysis of the Literature.

January 2025
Department of Oral and Maxillofacial Pathology, School of Dentistry, Universidade de Pernambuco, Recife, Pernambuco, Brazil.
Aims: Kallmann syndrome (KS) is a rare genetic disorder characterized by congenital hypogonadotropic hypogonadism and varied clinical features. Despite its recognition, the oral and maxillofacial manifestations remain poorly understood. This study synthesized clinical aspects and management of KS-related oral and maxillofacial alterations.

The APOE4 allele is the strongest genetic risk factor for sporadic Alzheimer's disease (AD). While APOE4 is strongly associated with amyloid-beta (Aβ), its relationship with tau accumulation is less understood. Studies evaluating the role of APOE4 on tau accumulation showed conflicting results, particularly regarding the independence of these associations from Aβ load.
