Can inflammasomes promote the pathophysiology of glioblastoma multiforme? A view about the potential of the anti-inflammasome therapy as pharmacological target.

Glioblastoma multiforme (GBM) is a malignant brain tumor with one of the worst general survivorship cases among the existing neoplasia. This aggressiveness is due to its complex molecular heterogeneity, immunohistochemistry and genetics. The current therapeutic approach brings little contribution to the improvement of the survival of the patients. Due to that, new forms of treatment have been explored, one of them being immunotherapy. In this aspect, the inflammasome pathway, which induces inflammation and immunosuppressive tumor response, contributing to the progression of the tumor, seems to be a new alternative to improve the treatment efficacy and the survival of the patients.

Clinical manifestations and factors associated with mortality from COVID-19 in older adults: Retrospective population-based study with 9807 older Brazilian COVID-19 patients.

AIM: Older adults are the main risk group for coronavirus disease 2019 (COVID-19). This study aimed to describe the clinical manifestations and factors associated with mortality from COVID-19 among older adults in Brazil. METHODS: A cross-sectional observational study was carried out with data from 9807 cases of COVID-19 among older adults in the state of Alagoas, Brazil. We determined the case fatality rate between age groups and clinical factors associated with mortality. RESULTS: A total of 52.5% (n = 5145) were women, and with an average age of 70.21 ± 8.37 years. The fatality rate was 11.9%, with a higher rate in men (14.4%) compared with women (9.8%). The fatality rate increased with age. The most common manifestations were fever (n = 4926; 50.2%), cough (n = 5737; 58.5%), headache (n = 1980; 20.2%) and fatigue (n = 2022; 20.6%). The most prevalent comorbidities were diabetes (n = 1528; 5.6%), cardiovascular disease (n = 1528; 15.6%) and systemic arterial hypertension (n = 597; 6.1%). The factors associated with mortality were male sex (OR 1.54), age ≥75 years (OR 2.40), dyspnea (OR 2.92), diabetes (OR 2.33), hypertension (OR 1.53) and chronic kidney disease (OR 2.02). CONCLUSIONS: The profile and the risk factors evidenced show the need to adopt mechanisms to protect the elderly population.
