Cognitive function and impact on driving after SARS-COV-2 infection in a man with long-standing HIV infection: a case report

A substantial number of individuals who experience COVID-19 infection experience prolonged physical and mental symptoms after resolution of their initial infection, and among them, many individuals experience cognitive difficulties including memory lapses and executive function difficulties, often referred to as "brain fog." The possible impact of COVID-19 infection on cognition in persons with HIV-related cognitive disorders is unknown. In this report, we describe post-COVID-19 cognitive and driving function in a 62-year-old man with HIV infection since the early 1990s.

Impact of COVID-19 pandemic on road safety in Tamil Nadu, India

This study uses structured literature mapping to review worldwide trends in traffic safety following the phenomenon of the COVID-19 pandemic. Motivated by dissimilar findings globally and a lack of evidence from emerging nations which have been significantly more affected by road traffic crashes, the study examines the impact of the pandemic-induced lockdown on road traffic deaths and injuries in Tamil Nadu, India. Using a holistic approach, methods such as ARIMA, Holt-Winters, Bayesian Structural Time Series, and Generalized Additive Model are employed for counterfactual prediction, to draw a causal inference of lockdown on traffic safety. In line with global studies, a substantial reduction in traffic crashes, injuries, and fatalities during lockdowns has been found. However, the comparison of relative differences shows that the number of grievous injuries reduced more than minor injuries, crashes, or fatalities. Furthermore, these relative differences were sustained even when metrics returned to normalcy in the post-lockdown phases. Further spatial stratification at two levels (cities and districts) shows that the macroscopic state-level trends are also broadly seen in the sub-units. This validates the consistency of trends across rural-urban differences and shows that, despite variations in the degree of enforcement of the lockdown within Chennai city, contrary to expectation, increased police presence did not have a differential impact on road crashes.
