The scientific literature on COVID-19 is rapidly evolving and these articles were selected for review based on their relevance to Washington State decision making around COVID-19 response efforts. Included in these Lit Reps are some manuscripts that have been made available online as pre-prints but have not yet undergone peer review. Please be aware of this when reviewing articles included in the Lit Reps.<\/p>\n
Today’s summary is based on a review of 667 articles (606 published, 61 in preprint).<\/em><\/p>\n \t\t\t\t<\/p>\n [Pre-print, not peer-reviewed]<\/i> Among 456 patients with clinical suspicion of COVID-19 and an initial negative PCR result for SARS-COV-2 by nasopharyngeal swab (March 1 to April 12, 2020), 94 (20%) were later confirmed as clinical COVID-19 cases. Among these, 47 (50%) tested positive with repeat PCR testing and 41 (44%) continued to have negative PCR results but were diagnosed from clinical documentation, discharge summary, or death certificate. These results are based on a review of medical admissions records at Imperial College Healthcare Trust in London, UK. The authors suggest health systems should recognize and plan for the management of swab-negative patients in their COVID-19 clinical management, infection control policies, and epidemiological assessments.<\/p>\n Middleton et al.

By comparison, only 15% of asymptomatic carriers had olfactory deficits detected by subjective evaluation. This method evaluated a combination of olfactory detection abilities at threshold levels and olfactory matching skills reflecting cognitive functioning.<\/p>\n Bhattacharjee et al. (Oct 16, 2020).

The use of ACEI\/ARB was also not associated with the risk of mortality (aOR=0.87, 95%CI 0.66-1.04) and severe outcomes (aOR=0.95, 95%CI 0.73-1.24).

Willingness to receive a vaccination was associated with healthcare attitudes and practices, political partisanship, and demographic characteristics including age, gender, and race\/ethnicity.\u00a0<\/span><\/p>\n Kreps et al.

The detection of IgG antibodies remained robust, with confirmed neutralization activity for up to six months. The study cohort included 307 COVID-19 hospital patients and healthcare workers at a central hospital, 38 staff members at the University of Lisbon who were tested positive during the mass screening, and 198 plasma donors who registered voluntarily online in Portugal.\u00a0<\/span><\/p>\n Figueiredo\u2010Campos et al.

The cognitive deficit was evaluated through tests of semantic problem solving, spatial working memory, selective attention and emotional processing.

In April 2020, the national excess all-cause mortality was 2.4 per 10,000 individuals and employment displacement was 9.9 per 100 individuals. The authors identified the excess mortality was highly concentrated, with the two states (New York and New Jersey) accounting for about half of the national excess mortality. In contrast, the impact on employment displacement was more spread out, with the two states with the highest employment displacement (Nevada and Michigan) accounting for only 7% of the national displacement.\u00a0<\/span><\/p>\n Polyakova et al.
