What is the association of masking behavior with SARS-CoV-2 infection? GWtweets SARSCoV2 COVID19 Masking Mask FaceMasks
By Tarun Sai LomteOct 12 2022Reviewed by Aimee Molineux A recent study published in the American Journal of Infection Control evaluated the associations between masking behavior and coronavirus disease 2019 .
About the study In the present study, researchers assessed the associations between self-reported masking behavior and the risk of SARS-CoV-2 infection. They used data from a prospective COVID-19 surveillance study, the North Carolina COVID-19 Community Research Partnership . Participants were enrolled at six sites and recruited through public websites, patient portals, and community outreach.
Similarly, recent exposure to SARS-CoV-2 was categorized as ‘yes’ or ’no’ based on contact with an infected individual in the preceding ten days. A nested case-control analysis compared self-reported COVID-19 cases to controls who did not report a positive COVID-19 test. Each case was matched to up to 10 controls using an optimal algorithm that assigned a maximum number of controls to cases.
More than 42% of cases and 36.3% of controls reported not wearing masks at least once in the ten days before the match date. Most cases reported contact with a COVID-19-positive individual in the past ten days before the index date, compared to 9.3% of controls. Masking behavior differed across the three COVID-19 periods. Reports of not using masks among all participants were the lowest in the pre-Delta period.

Elevated vascular transformation blood biomarkers in Long-COVID indicate angiogenesis as a key pathophysiological mechanism - Molecular MedicineBackground Long-COVID is characterized by prolonged, diffuse symptoms months after acute COVID-19. Accurate diagnosis and targeted therapies for Long-COVID are lacking. We investigated vascular transformation biomarkers in Long-COVID patients. Methods A case–control study utilizing Long-COVID patients, one to six months (median 98.5 days) post-infection, with multiplex immunoassay measurement of sixteen blood biomarkers of vascular transformation, including ANG-1, P-SEL, MMP-1, VE-Cad, Syn-1, Endoglin, PECAM-1, VEGF-A, ICAM-1, VLA-4, E-SEL, thrombomodulin, VEGF-R2, VEGF-R3, VCAM-1 and VEGF-D. Results Fourteen vasculature transformation blood biomarkers were significantly elevated in Long-COVID outpatients, versus acutely ill COVID-19 inpatients and healthy controls subjects (P | 0.05). A unique two biomarker profile consisting of ANG-1/P-SEL was developed with machine learning, providing a classification accuracy for Long-COVID status of 96%. Individually, ANG-1 and P-SEL had excellent sensitivity and specificity for Long-COVID status (AUC = 1.00, P | 0.0001; validated in a secondary cohort). Specific to Long-COVID, ANG-1 levels were associated with female sex and a lack of disease interventions at follow-up (P | 0.05). Conclusions Long-COVID patients suffer prolonged, diffuse symptoms and poorer health. Vascular transformation blood biomarkers were significantly elevated in Long-COVID, with angiogenesis markers (ANG-1/P-SEL) providing classification accuracy of 96%. Vascular transformation blood biomarkers hold potential for diagnostics, and modulators of angiogenesis may have therapeutic efficacy.
