Study suggests algal polysaccharide may be a promising anti-COVID-19 candidate

Researchers from the Rensselaer Polytechnic Institute have been investigating the potential of rhamnan sulfate as an antiviral agent.

AI could help predict the necessity of ICU admission during COVID-19 pandemic

New technology could help doctors make the most of limited resources during the COVID-19 pandemic by identifying patients who require intensive care unit (ICU) treatment.

Scientists develop and characterize variant-specific vaccines against SARS-CoV-2

In a recent study conducted at Yale University, USA, scientists have investigated the immunogenicity of mRNA-based coronavirus disease 2019 (COVID-19) vaccine candidates encoding the spike proteins of different severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants. The findings reveal that the vaccines induce robust immune responses against SARS-CoV-2 variants. The study is currently available on the bioRxiv* preprint server.

An analysis of risk factors and symptom presentation among groups at risk for SARS-CoV-2 infection

The study, published on the pre-print server medRxiv*, analyzed the specific linkages between the COVID-19 patients belonging to the three risk groups with the overall COVID-19 patients and compared symptoms between and within the risk groups.

COVID-19 severity is correlated with T cell receptor repertoire signatures

In a new study published in the bioRxiv* preprint server, researchers found that specific TCR sequences predicted the severity of coronavirus disease 2019 (COVID-19) infection. Additionally, there was evidence of increased CDR3 sequences and changes in k-mer motifs for patients with severe illness.

Simple quantitative framework to understand the pathogenesis of severe COVID-19

Researchers from Los Alamos National Laboratory in the United States developed a model to explain why severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections induce high inflammatory levels.

Omicron variant increases risk of SARS-CoV-2 reinfection

New surveillance data from South Africa published in the medRxiv* preprint server suggests that the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omnicron variant has the potential to escape naturally-acquired immunity. The research indicates people who previously recovered from a coronavirus disease 2019 (COVID-19) are at risk for reinfection with the Omicron variant. The results show that the risk of reinfection is greater with the Omicron variant versus Delta and Beta.

Disparities in maternal mental health during COVID-19

In new research, scientists studied individuals who gave birth during COVID-19. Using propensity score matching (PSM), they matched those identified as either Black or Latinx with those identified as non-Hispanic white on sociodemographic. This recent study published as a preprint on the medRxiv* server attempts to assess the impact of the COVID-19 pandemic on childbirth-related health outcomes in individuals belonging to Black or Latinx minority groups.

SARS-CoV-2 S2 immunization as a pan-coronavirus vaccine approach

A new mouse model suggests that prior HCoV-OC43 S immunity primes neutralising antibody responses to otherwise subimmunogenic SARS-CoV-2 S exposure as well as promotes S2-targeting antibody responses.

Scientists find infection of sustentacular cells in the olfactory epithelium of COVID-19 patients

It is now widely known that COVID-19 is associated with the transient or long-term loss of olfaction (the sense of smell) but the mechanisms remain obscure.

Lack of computer access in COVID predicts lower mental health among adolescents

A new study discusses adolescent mental health during the pandemic in association with the availability of digital access through computers to do schoolwork.

COVID symptom attestation tool for health care workers helps protect patients and co-workers

Any fever or chills? Cough? Shortness of breath? Answering these questions and others has become a familiar part of daily life during the pandemic.

Study shows COVID booster shots work

A new study investigates uses seven different COVID-19 vaccines as the third dose to boost immunity in vulnerable patients.

SARS-CoV-2 Delta saliva viral load 15 times that of the wild type

Researchers hypothesize that a higher viral load of SARS-CoV-2 Delta variant in saliva contributes to its high transmissibility.

Hospitalization trends and associated factors for COVID in 2.3 million adults in England

Researchers performed a retrospective cohort study to determine risk factors for hospitalization and mortality rates over time among COVID-19 patients.

New marker could lead to better diagnoses of Covid-19

Biomedical scientists at LMU have found a new marker in the blood of Covid-19 patients. It furnishes insights into the course and development of the disease and could lead to better diagnoses.

SARS-CoV-2 virus-like particles elicit potent neutralizing antibody response in variant challenge

Researchers develop a virus-like particle for SARS-CoV-2 based on the co-expression of the spike, membrane, and envelope structural proteins.

Inequalities of the US COVID-19 vaccination drive

The percentage of individuals with at least one dose of a COVID-19 vaccine, by communities, were collected from eight cities to determine US vaccine inequality.

Safety and immunogenicity of SARS-CoV-2 recombinant spike protein vaccine

Researchers have presented the results of phase 1 and phase 2 clinical trials of a SARS-CoV-2 recombinant spike protein vaccine (Abdala).
