SARS-CoV-2 infection shown to reduce the expression of vitamin D pathway components

A recent computational study from India implicated a dysregulated vitamin D pathway in the pathobiology of the infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – and opened the door for experimental validation of these observations.

As the terror of COVID struck, health care workers struggled to survive. Thousands lost the fight.

Workers at Garfield Medical Center in suburban Los Angeles were on edge as the pandemic ramped up in March and April. Staffers in a 30-patient unit were rationing a single tub of sanitizing wipes all day. A May memo from the CEO said N95 masks could be cleaned up to 20 times before replacement.

More than 2,900 health care workers died this year — and the government barely kept track

More than 2,900 U.S. health care workers have died in the COVID-19 pandemic since March, a far higher number than that reported by the government, according to a new analysis by KHN and The Guardian.

Public adherence to COVID-19 guidelines in Norway: a case study

To evaluate and understand the adherence to public health actions recommended by the government, a team in Norway undertook a study funded in part by the Norwegian Research Council’s Centres of Excellence Funding Scheme and by the project: A realtime analytical pipeline for preparedness, planning, and response during the COVID-19 pandemic in Norway.

E-cigarettes, as consumer products, are not associated with smoking cessation

E-cigarette use has risen steeply and mostly without regulation over the past decade. The devices have diversified into a dizzying array of vape pens, tank systems, "mods," and more, mass-marketed and sold to the public.

First UK lockdown during COVID-19 pandemic negatively impacted dementia care

Researchers in the United Kingdom have conducted an extensive survey exploring the impact that lockdown had on people living with low prevalence and young-onset dementias during the first wave of the coronavirus disease 2019 (COVID-19) pandemic.

Giving antimalarial medicines to children during the rainy season reduces malaria deaths

Giving antimalarial medicines to children monthly during the rainy season cut malaria deaths in children by 42 per cent, making a case for wide implementation in malaria-endemic African regions, a study found.

Modeling the phases of quarantine reveals two-phase route is always better than one

New research into this question shows that the second wave of an epidemic is very different if a population has a homogenous distribution of contacts, compared to the scenario of subpopulations with diverse number of contacts.

SARS-CoV-2 mutations may evade T cell immunity

A potentially disturbing new study suggests that SARS-CoV-2 may be undergoing strategic mutations that affect the host immune capacity to recognize and combat the pathogen via T effector cells.

Researchers use fruit fly model to understand COVID-19-related neurological complications

Researchers claim to have reproduced disease mechanisms due to coronavirus disease 2019 (COVID-19) in the fruit fly, Drosophila, while also providing proof of the efficacy of one drug against these disease processes. If validated, these findings represent a new understanding of how the virus causes neurological symptoms that could help develop more effective therapies.
