New study links persistent SARS-CoV-2 proteins to long COVID symptoms

Brigham researchers found people with wide-ranging long COVID symptoms were twice as likely to have SARS-CoV-2 proteins in their blood, compared to those without long COVID symptoms.

COVID-19 significantly raises stroke risk

Researchers conducted a metaumbrella review of 34 systematic reviews and 70 studies, uncovering a significant link between COVID-19 severity and increased stroke risk. The review emphasizes the need for further investigation into underlying mechanisms and potential biases.

Novel compounds show promise in fighting COVID-19

New research from The Wistar Institute's Salvino lab -; led by professor Joseph Salvino, Ph.D. -; has identified a novel series of SARS-CoV-2 Mpro inhibitors that may lead to potential new COVID-19 treatments that, according to preclinical testing, effectively inhibits COVID-19 and synergizes with existing anti-COVID therapies.

Antigenic mapping sheds light on SARS-CoV-2 immunity differences

A person's immune response to variants of SARS-CoV-2, the virus that causes COVID-19, depends on their previous exposure - and differences in the focus of immune responses will help scientists understand how to optimise vaccines in the future to provide broad protection.

COVID-19 increases chronic fatigue risk

Study reveals that COVID-19 significantly increases the risk of chronic fatigue syndrome, with specific populations, such as older adults, Asians, and non-hospitalized patients, at higher risk.

Study reveals high effectiveness of flu vaccines in children but highlights challenges with certain subtypes

Study found that influenza vaccination is highly effective in preventing infection and hospitalization in children, though efficacy against certain subtypes like H3N2 remains limited due to small sample sizes.

Thousands could have been saved during the pandemic with expanded use of convalescent plasma

A new study led by researchers at Johns Hopkins Bloomberg School of Public Health estimates that thousands of lives could have been saved during the first year of the COVID-19 pandemic if convalescent plasma had been used more broadly, particularly in outpatients at high risk for severe disease and in hospitalized patients during their first few days of admission.

Mild COVID-19 disrupts brain connectivity and reduces memory function in adolescents and young adults

Study reveals localized brain changes in adolescents and young adults post-COVID, including reduced hippocampal volume and disrupted connectivity, correlating with impaired working memory. These findings highlight the importance of understanding long-term cognitive effects of mild COVID-19.

Long-lived plasma cells fail to establish after COVID mRNA vaccination, limiting long-term antibody response

Researchers found that SARS-CoV-2-specific plasma cells were largely excluded from the long-lived plasma cell compartment in the bone marrow after mRNA vaccination, explaining the short-lived antibody response.

Long COVID affects 38% of emergency patients with persistent symptoms

Researchers found that post-COVID-19 condition (PCC) symptoms persist in a significant number of both SARS-CoV-2 positive and negative emergency department patients, highlighting the non-specific nature of the WHO’s PCC criteria.

New humanized mouse models created to study COVID-19

Scientists at La Jolla Institute for Immunology (LJI) have developed six lines of humanized mice that can serve as valuable models for studying human cases of COVID-19.

Study reveals widespread long-COVID symptoms, challenging WHO definition

Study reveals that more than one-third of SARS-CoV-2 positive patients experience long-COVID symptoms three months after an emergency department visit, with significant overlap in symptoms observed among negative patients.

COVID-19 vaccine uptake higher in people with mental illness but drops for those not on medication

Researchers examined the link between mental illness and COVID-19 vaccine uptake, finding high vaccination rates but lower uptake among unmedicated individuals with mental health conditions.

COVID-19 vaccine uptake among pregnant women higher than expected

A study of more than 28,000 pregnancies from 2022 has found that the majority of pregnant people received the COVID-19 vaccine during its initial release.

Macrophage memory following COVID infection provides cross-virus protection

More than 200 viruses can infect and cause disease in humans; most of us will be infected by several over the course of a lifetime.

How viral persistence and immune dysfunction drive long COVID

Study explores the biological drivers and mechanisms of long COVID, shedding light on its epidemiology and potential therapeutic interventions. It emphasizes the role of viral persistence, immune dysfunction, and coagulation in the development of this condition.
