1q21gain/amp is the most common in patients with multiple myeloma. However, there is limited research on the prognostic heterogeneity of 1q21+, and the prognostic of the 1q21 copy remains controversial. In this study, we primarily conducted a retrospective analysis of the prognostic significance of 1q21 gain/amp in 375 newly diagnosed multiple myeloma patients.

Previous reports of CBS-LBD describe patients with diffuse LBD, a younger age of onset and occasionally lacking core features like REM sleep Behavior Disorder (RBD).
Method: We present a young patient with CBS who had a rapid progression and was found to have a high burden of limbic LBD and high AD co-pathology at autopsy.
Rising Voltage-Gated Potassium Channel Antibody Level as a Possible Disease Progression Marker for Amyotrophic Lateral Sclerosis: A Case Report.

A subset of amyotrophic lateral sclerosis (ALS) patients tests positive for antibodies commonly associated with autoimmune neurological diseases, including voltage-gated potassium channel (VGKC)-complex antibodies. Although an autoimmune basis for ALS remains speculative, and immunomodulatory therapies have shown minimal benefit as of yet, isolated cases suggest that VGKC-complex antibodies may be relevant to disease type and progression. In this report, we present a case of ALS in which increasing VGKC-complex antibody levels correlated with clinical decline, raising the question of whether such antibodies could serve as biomarkers of progression in VGKC-complex antibody-positive ALS patients.

Unlabelled: QUESTIONS AND RECOMMENDATIONS FROM THE PRIOR VERSION OF THESE GUIDELINES WITHOUT CHANGE: TARGET POPULATION: Adult patients (age ≥ 18 years) who have suspected low-grade diffuse glioma.
Question: What are the optimal neuropathological techniques to diagnose low-grade diffuse glioma in the adult?
Recommendation: Level I Histopathological analysis of a representative surgical sample of the lesion should be used to provide the diagnosis of low-grade diffuse glioma. Level III Both frozen section and cytopathologic/smear evaluation should be used to aid the intra-operative assessment of low-grade diffuse glioma diagnosis.
Multiomics analysis reveals the involvement of NET1 in tumour immune regulation and malignant progression.

Neuroepithelial cell transforming gene 1 (NET1) is a member of the Ras homologue family member A (RhoA) subfamily of guanine nucleotide exchange factors and a key protein involved in the activation of Rho guanosine triphosphatases, which act as regulators of cell proliferation, cytoskeletal organization, and cell movement and are crucial for cancer spread. Research has shown that NET1 can regulate the malignant biological functions of tumour cells, such as growth, invasion, and metastasis, and it is closely related to the progression of pancreatic cancer, gastric cancer, and liver cancer. However, the comprehensive role and mechanistic function of NET1 in other types of cancer remain largely unexplored.
