Utility of ISARIC 4C Mortality Score, Vaccination History, and Anti-S Antibody Titre in Predicting Risk of Severe COVID-19.

The ISARIC 4C Mortality score was developed to predict mortality risk among patients with COVID-19. Its performance among vaccinated individuals is understudied. This is a retrospective study of all patients with SARS-CoV-2 infection admitted to the National Centre for Infectious Diseases, Singapore, from January-2020 to December-2021.

Proximal Renal Artery Stenosis Presenting as Uncontrolled Hypertension.

Presentation: We present a case of 50-year-old lady who present with 1-month history of uncontrolled hypertension.

Diagnosis: Magnetic resonance angiography showed stenosis of the left renal artery just beyond the ostium extending over approximately 7mm in length. Computed tomography angiography show focal narrowing of the proximal renal artery just distal to vessel origin, approximately 60% stenosis.

A covalent creatine kinase inhibitor ablates glioblastoma migration and sensitizes tumors to oxidative stress.

Glioblastoma is a Grade 4 primary brain tumor defined by therapy resistance, diffuse infiltration, and near-uniform lethality. The underlying mechanisms are unknown, and no treatment has been curative. Using a recently developed creatine kinase inhibitor (CKi), we explored the role of this inhibitor on GBM biology in vitro.

B cell-based therapy produces antibodies that inhibit glioblastoma growth.

Glioblastoma (GBM) is a highly aggressive and malignant brain tumor with limited therapeutic options and a poor prognosis. Despite current treatments, the invasive nature of GBM often leads to recurrence. A promising alternative strategy is to harness the potential of the immune system against tumor cells.
