Background Post-traumatic stress disorder (PTSD) is a severe but treatable mental disorder that develops after a life-threatening traumatic event. Coronavirus disease 19 (COVID-19) hospitalisation is a potentially traumatic experience, especially in severe cases. Furthermore, the unprecedented context of the severe acute respiratory syndrome coronavirus 2 pandemic, with daily media bombardment about COVID-19 mortality, may have amplified life-threatening perception also in patients with moderate infection. The aim of this study was to assess the prevalence and risk factors of PTSD at 3-month follow-up in patients hospitalised for COVID-19 infection. Design In this cohort follow-up study conducted in a large Italian academic COVID-19 hospital, 115 recruited survivors were contacted by telephone 3 months after discharge to home care. The Posttraumatic Stress Disorder Checklist for DSM-5 was administered. Multivariate logistic regression models were used to analyse risk factors for the development of PTSD. Key Results A total of 10.4% of the sample received a PCL-5-based diagnosis of PTSD. Other 8.6% of the sample received a diagnosis of subthreshold PTSD, which leads to significant levels of distress and impairment. Multivariate regression analysis indicated that previous psychiatric diagnosis (odds ratio (OR) = 6.3, 95% confidence interval (CI): 3.7–78.6, p < 0.001) and obesity (OR = 3.51, 95% CI: 1.4–857.9, p = 0.03) were risk factors for developing PTSD. Chronic pulmonary diseases approached significance as a risk factor (OR = 6.03, 95% CI: 1.0–37.1, p = 0.053). Male sex was a protective factor (OR=0.04, 95% CI: 0.0–0.041, p = 0.007). Conclusions PTSD and subthreshold PTSD rates in patients hospitalised for COVID-19 are worrying. Female sex and pre-existing mental disorders are established risk factors for PTSD, while the prospective association with obesity needs further investigation. Clinicians treating COVID-19 should consider screening for PTSD at follow-up assessments in patients discharged from the hospital.

Tumor progression, limited efficacy of current standard treatments, and the rise in patient mortality are associated with gene expression caused by the synergistic action of intratumoral hypoxia and HIF-1α activation. For this reason, recent investigations have focused on HIF-targeting therapeutic agents, with encouraging preclinical and clinical results in solid tumors. Here we describe the efficacy of a HIF-1α inhibitor, Acriflavine, and demonstrate its potency against brain cancer. This safe antibacterial dye induces cell death and apoptosis in several glioma cell lines, targets HIF-1α–mediated pathways, and decreases the level of PGK1, VEGF and HIF-1α in vitro and in vivo. Administered locally via biodegradable polymers, Acriflavine provides significant benefits in survival resulting in nearly 100% long term survival, confirmed by MRI and histological analyses. This study reports preclinical evidence that this safe, small molecule can contribute to brain tumor therapy and highlights the significance of HIF-1α-targeting molecules.

The growing cost of medical care worldwide, particularly in oncology, has incentivized researchers and physicians to repurpose clinically used drugs to alleviate the financial burden of drug development and offer potential new therapeutics. Recent works have demonstrated anticancer properties of the FDA-approved drug ribavirin, a synthetic guanosine analogue and antiviral molecule used over the past four decades for the treatment of hepatitis C. The efficacy of ribavirin in cancer has been explored through several preclinical models and ongoing clinical trials in multiple cancers, including acute myeloid leukemia, oropharyngeal squamous cell carcinoma, and metastatic breast cancer. In this review, we summarize the role of ribavirin as an antiviral medication and focus our attention on its recent use as an antitumoral agent. We highlight current knowledge of the potential use and mechanisms of action of ribavirin in cancer. Because current therapeutics for patients with cancer still fail to cure, introducing new forms of treatment is essential. Converging evidence suggests that ribavirin represents a promising addition to a generation of newly repurposed safe and effective anticancer agents.
