Large U.S. study identifies sociodemographic and clinical factors associated with SARS-CoV-2 testing and positivity

The massive and continuing outbreak of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), throughout the world, has led to a staggering toll of over 549,000 deaths in the USA, among over 30 million cases. A new preprint research paper posted to the medRxiv* server discusses the factors related to the chances of testing positive for this virus.

Persistent impact on smell and taste in COVID-19 patients one year later

The presentation of the infection ranges from asymptomatic, through dry cough with fever, anosmia/dysgeusia, to shortness of breath with severe acute respiratory distress syndrome (ARDS). A new preprint research paper posted to the medRxiv* server reports on the clinical progression of anosmia and dysgeusia, in particular, one year after the infection.

Combination of X-rays and AI can serve as rapid diagnostic tool for COVID-19

X-rays, first used clinically in the late 1890s, could be a leading-edge diagnostic tool for COVID-19 patients with the help of artificial intelligence, according to a team of researchers in Brazil who taught a computer program, through various machine learning methods, to detect COVID-19 in chest X-rays with 95.6 to 98.5% accuracy.

AstraZeneca's COVID-19 vaccine protects against symptomatic disease

Results from a large clinical trial in the United States and South America indicate that AstraZeneca's COVID-19 vaccine, AZD1222, is well-tolerated and protects against symptomatic COVID-19 disease, including severe disease or hospitalization.

What are the chief predictors of SARS-CoV-2 infection in children?

A new study seeks to explore the factors associated with the diagnosis in children. The ability to rapidly diagnose COVID-19 in this age group is essential not only for monitoring progressive disease in individual children, but to avert further transmission chains.

New drug regimen is safe and effective in children with cystic fibrosis

An international, open-label Phase 3 study, co-led by Susanna McColley, MD, from Ann & Robert H. Lurie Children's Hospital of Chicago, found that a regimen of three drugs (elexacaftor/tezacaftor/ivacaftor) that targets the genetic cause of cystic fibrosis was safe and effective in 6-11-year-olds with at least one copy of F508del mutation in the CFTR gene, which is estimated to represent almost 90 percent of the cystic fibrosis population in the United States.

Study of post-acute sequelae of SARS-CoV-2 infection shows persistent symptoms 8 months

Researchers from the US recently studied the prevalence of PASC in a well-characterized cohort of patients to gain insights into the period following acute SARS-CoV-2 infection. The research is posted online to the preprint server medRxiv.

COVID-19 survivors experience symptoms up to 10 months after infection, study finds

Coronavirus disease (COVID-19) symptoms are increasingly recognized to persist among a subset of individuals following acute infection, but features associated with this persistence are not well-understood.

For Covid ‘long haulers,’ battling for disability benefits adds aggravation to exhaustion

Rickie Andersen took a brief break from work in March after she fell ill. Her cough, fever and chills were typical covid-19 symptoms, but coronavirus tests were so scarce she could not obtain one to confirm the diagnosis.

Self-assembling nanoparticles an effective vaccine candidate for SARS-CoV-2

The currently developed vaccines against SARS-CoV-2 include the RBD in their immunogen. With a similar objective, a new study developed an RBD protein-based vaccine candidate against the SARS-CoV-2, using self-assembling Helicobacter pylori-bullfrog ferritin nanoparticles as an antigen delivery system. The study is published recently in the journal mBio (by the American Society of Microbiology).
