Age- and gender-specific molecular characteristics of diffuse large B-cell lymphoma: Results from clinical trials of the DSHNHL/GLA.

Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma. Despite a high cure rate, too many patients show refractory (ref) or relapsed (rel) disease. This study examines the frequency of recurring gene mutations and their interplay with well-known biomarkers in female and male patients between 18 and 80 years with ref/rel DLBCL compared to patients with complete remission (CR) to identify biological risk factors associated with treatment response, using cohorts of R-CHOP-like treated DLBCL enrolled in clinical trials of the DSHNHL.

A dose escalation and safety study of AAVrh10-mediated Schwann cell-targeted gene therapy for CMT1X.

X-linked Charcot-Marie-Tooth disease (CMT1X) is an inherited demyelinating neuropathy caused by loss-of-function mutations in the GJB1 gene, encoding the gap junction protein connexin32 (Cx32). Cx32 plays a critical role in Schwann cell function and myelin formation in the peripheral nervous system. We have developed a gene replacement therapeutic approach using a humanized AAVrh10 vector construct expressing GJB1 under the control of the Schwann cell-specific human myelin protein zero (MPZ) promoter.

Development of Hybrid radiomic Machine learning models for preoperative prediction of meningioma grade on multiparametric MRI.

Purpose: To develop and compare machine learning models for distinguishing low and high grade meningiomas on multiparametric MRI.

Methods: Pre-operative T1-weighted(T1), contrast-enhanced T1-weighted(T1CE), T2-weighted, T2 FLAIR, and DWI/ADC MRI sequences of meningiomas performed between 2000 and 2020 were retrospectively collected from a single tertiary hospital dedicated neurosurgical department. Tumours were manually segmented and handcrafted radiomic features were extracted.

Dietary Nut and Legume Intake and Risk of Crohn's Disease and Ulcerative Colitis.

Background: We investigated the relationship between nut and legume intake and risk of Crohn's disease (CD) and ulcerative colitis (UC).

Methods: We conducted a prospective cohort study of 223 283 adults from the Nurses' Health Study (NHS), NHSII, and Health Professionals Follow-Up Study (1986-2017), excluding those with inflammatory bowel disease (IBD) at baseline. Food frequency questionnaires were used to calculate nut and legume intake.

Vertebroplacental ratio for prediction of perinatal outcome and operative delivery for suspected fetal compromise: prospective observational cohort study.

Objective: To investigate differences in fetal vertebroplacental ratio (VPR) depending on the occurrence of operative delivery for suspected fetal compromise (ODFC) and composite perinatal outcome (CPO) at delivery.

Methods: This was a prospective observational cohort study conducted in the Department of Obstetrics and Gynecology at the University Hospitals of Leuven, Leuven, Belgium, between December 2022 and April 2024. Women with a term (37-42 gestational weeks) singleton pregnancy with an appropriate-for-gestational-age (AGA) fetus were recruited, before cervical dilatation reached 5 cm, for sonographic fetal weight estimation (EFW) and Doppler sonography of the umbilical artery (UA), umbilical vein (UV), middle cerebral artery (MCA) and vertebral artery (VA).
