Is COVID-19 a new disease?

In a review recently published in The Lancet Respiratory Medicine journal by Osuchowski et al. (May 6th, 2021) the currently known pathophysiology of COVID-19 is laid out to describe the mechanistic features that make COVID-19 distinct from many conditions previously thought to be similar.

Researchers identify anti-inflammatory prodrug Minnelide with potential against SARS-CoV-2

Using a transgenic mouse model of COVID-19, they have observed that treatment with Minnelide reduces viral load and inflammation in the lungs and improves survival. The study is currently available on the bioRxiv* preprint server.

Increased heart rate as a physiological response to SARS-CoV-2 mRNA vaccine

Although widely publicized, evidence for physiological responses to the vaccines is currently scarce in published literature. Giogiro Quer and Matteo Gadaleta of the Scripps Research Translational Institute in California, USA, led an investigation to obtain tracking data for physiological responses to vaccine programs.

Unique infectious profile explains why it is so hard to treat COVID-19

A comprehensive review into what we know about COVID-19 and the way it functions suggests the virus has a unique infectious profile, which explains why it can be so hard to treat and why some people experience so-called "long-COVID", struggling with significant health issues months after infection.

CFTR modulator can be safe, well-tolerated for younger children with common form of cystic fibrosis

Children ages two to five who have the most common form of cystic fibrosis (CF), caused by two copies of the F508 gene mutation, have not had any modulator treatments available to them until recently.

Supervised rehabilitation program can help patients with lasting symptoms of COVID-19

Patients with lasting symptoms of COVID-19 who completed a six week, supervised rehabilitation programme demonstrated significant improvements in exercise capacity, respiratory symptoms, fatigue and cognition, according to researchers at the National Institute for Health Research Leicester Biomedical Research Centre - a partnership between Leicester's Hospitals, the University of Leicester and Loughborough University.

Algorithms can assess unconsciousness under general anesthesia with accuracy and reliability

Anesthestic drugs act on the brain but most anesthesiologists rely on heart rate, respiratory rate, and movement to infer whether surgery patients remain unconscious to the desired degree.

UCL researchers highlight systemic inequalities in indoor air pollution exposure

Systemic inequalities mean that low-income households in London are more likely to be exposed to higher levels of indoor air pollution, according to a report by UCL researchers.

Pfizer-BioNTech mRNA vaccine reduces both symptomatic and asymptomatic COVID-19 infection in case study

Follow-up of vaccinated and unvaccinated individuals at St. Jude Children’s Research Hospital revealed asymptomatic infection reduced by 90% and symptomatic infections reduced by up to 96% in vaccinated people compared to those not vaccinated.

How did SARS-CoV-2 first evolve in humans?

In a perspective article recently published in the journal Science, Hyeryun Choe and Michael Farzan from the Scripps Research Institute, USA, have described the early-stage evolution of SARS-CoV-2 in humans. They have provided a detailed overview of how early mutations in SARS-CoV-2 spike protein facilitate its adaptation in human systems.

Immunosuppression in COVID-19 promotes emergence of multiple immune escape mutants

An interesting new study describes the emergence of several such variants from a chronically immunosuppressed COVID-19 patient, who remained infected for over 170 days before clearing the virus.

The ancestor of SARS-CoV-2’s Wuhan strain was circulating in late October 2019

The SARS-CoV-2 was first reported in a case from Wuhan, China, in December 2021, and subsequently became the cause of the COVID-19 pandemic that is ravaging the world today. A new study in the journal Molecular Biology and Evolution tracks its variants all over the world since the onset of the pandemic.

Are infants at greater risk of COVID-19 than children?

The widely circulating SARS-CoV-2 has caused the devastating COVID-19 pandemic. The impact of this infection varies significantly with age, sparing young children for the most part, though not completely. However, a new study, released as a preprint on the medRxiv* server, shows that infants are not as resistant to the virus as children are. The researchers trace this to the expression of ACE2 to varying extents in different groups.

Could antiviral surface designs help reduce SARS-CoV-2’s spread?

In an effort to improve surface decontamination methods, researchers from the Indian Institute of Technology (IIT), Bombay, looked at fabricating surfaces with virucidal properties. More specifically, these scientists investigated surface properties that could prevent the survival of viruses on these surfaces, particularly SARS-CoV-2.

Human organoids useful for modeling COVID-19 variants of concern, finds study

A new study published on the bioRxiv* preprint server found that using human organoids could help with better characterizing the phenotype of several viral variants, including B.1.1.7. Their findings show the ribonucleic acid (RNA) shedding of the SARS-CoV-2 variant correlated with viral fitness and infectiousness.

COVID-19 may impact the heart health of young, healthy adults

New research published in Experimental Physiology highlight the possible long term health impacts of COVID-19 on young, relatively healthy adults who were not hospitalized and who only had minor symptoms due to the virus.

Increased symptomatic levels of COVID-19 may be associated with psychiatric symptoms

A significant level of symptoms of depression, anxiety and post-traumatic stress may follow COVID-19 independent of any previous psychiatric diagnoses, according to new research by Columbia University Mailman School of Public Health with colleagues at Universidade Municipal de São Caetano do Sul in Brazil.

Highly efficient immune response in asymptomatic SARS-CoV-2 patients

Researchers in Singapore have investigated the role of SARS-CoV-2-specific antibodies and T-cells in asymptomatic individuals suffering from COVID-19. They found that, contrary to some initial hypotheses, asymptomatic individuals mount an adaptive immune response on par with symptomatic individuals, demonstrating that T cell response does not appear to be correlated with symptom severity.

SARS-CoV-2 infection prolongs viral shedding and lymphocyte loss in patients with cancer

Patients with cancer have a more challenging time with infections while undergoing treatment — placing them as high-risk for severe COVID-19 illness and death. However, how the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) interacts with cancer therapies remains poorly understood.

Global spread of COVID-19 has raised serious concern for patients with transthyretin amyloidosis

The global spread of COVID-19 has raised serious concern for patients with chronic disease. A correlation has been identified between the severity of COVID-19 and a patient's preexisting comorbidities.
