DIAPH3 predicts survival of patients with -methylated glioblastoma.

Background: Glioblastoma is one of the most aggressive primary brain tumors, with a poor outcome despite multimodal treatment. Methylation of the promoter, which predicts the response to temozolomide, is a well-established prognostic marker for glioblastoma. However, a difference in survival can still be detected within the methylated group, with some patients exhibiting a shorter survival than others, emphasizing the need for additional predictive factors.

Long-term survival in patients with IDH-wildtype glioblastoma: clinical and molecular characteristics.

Backg Round: Glioblastoma is an aggressive tumor that has a dismal prognosis even with multimodal treatment. However, some patients survive longer than expected. The objective of this study was to revisit patients diagnosed with glioblastoma according to the 2021 WHO classification and analyze clinical and molecular characteristics associated with long-term survival (LTS).

Chilblains observed during the COVID-19 pandemic cannot be distinguished from classic, cold-related chilblains.

Background: Type 1 interferon (IFN-I) response induced by SARS-CoV-2 has been hypothesized to explain the association between chilblain lesions (CL) and SARS-CoV-2 infection.

Objective: To explore direct cytopathogenicity of SARS-CoV-2 in CL and to focus on IFN-I expression in patients with chilblains.

Materials & Methods: A monocentric cohort of 43 patients presenting with CL from April 2020 to May 2021 were included.

Focal status epilepticus may trigger relapse of primary angiitis of the CNS.

The role of neuroinflammation in epileptogenesis is extensively investigated, but short-term effects of seizures on established CNS pathologies are less studied and less predictable. We describe the case of a woman with previous recurrent episodes of focal cerebral haemorrhage of unknown cause who developed a pseudo-tumoural oedema triggered by provoked focal status epilepticus. A brain biopsy revealed that the underlying condition was primary angiitis of the CNS.
