Genomic characterization of the SARS-CoV-2 Omicron lineages BA.4 and BA.5, responsible for the fifth COVID-19 pandemic wave in South Africa, shows continued viral diversification and provides insights into the potential mechanisms underlying the ability of the new lineages to outcompete their predecessors.
Analysis of the first sequences from the 2022 multi-country outbreak of monkeypox virus shows relatedness and substantial divergence from a 2018–2019 outbreak, suggesting rapid virus evolution with possible implications for human-to-human transmission.
Healthy individuals have antibodies and T cells that are reactive to the Cas13d protein from the bovine bacteria Ruminococcus flavefaciens, which may have implications for clinical testing of CRISPR–Cas13 gene editing approaches.
A new study reveals that polygenic scores for lipid traits derived from data of African American individuals have high predictive value in a South African Zulu cohort but are poor predictors in a cohort from Uganda, further highlighting the need to improve polygenic predictions in populations of African ancestries.
CoronaVac protects young children from severe COVID-19 during a SARS-CoV-2 Omicron surge, supporting the effectiveness and importance of vaccinating this pediatric population.
First responders to the World Trade Center disaster, who were exposed to particulate matter containing potential carcinogens, have a high burden of somatic mutations in blood cells, raising their risk for cancer and other diseases and highlighting the need for enhanced health screening of these individuals.
A multi-scale model using population-level transmission and individual-level vaccination data suggests that vaccine dose fractionation could be a cost-effective strategy for mitigating the COVID-19 pandemic in India.
Serum neutralizing antibody titers against the SARS-CoV-2 Omicron variant markedly increase after a third dose of BNT162b2 vaccine in individuals who previously received either two doses of the BNT162b2 vaccine or two doses of the CoronaVac vaccine.
BNT162b2 booster vaccination in individuals who had previously received two doses of CoronaVac elevates neutralizing antibodies against the Omicron variant, but titers remain reduced compared with those against the ancestral SARS-CoV-2 virus and the Delta variant.
Neutralization of the SARS-CoV-2 Omicron variant is markedly impaired in sera from recipients of two doses of the COVID-19 vaccine BNT162b2 or from convalescent individuals, but is robustly increased in both groups following a booster vaccine dose.
Peripheral ancestral SARS-CoV-2 spike-specific CD4+ and CD8+ T cells induced by BNT162b2 vaccination cross-react to the Omicron variant at higher levels than those induced by prior SARS-CoV-2 infection.
Biomarkers of red blood cell destruction were elevated in astronauts while on long-duration missions on the International Space Station, suggesting that hemolysis is a major contributor to space anemia.
A progressive movement disorder in a patient with multiple myeloma treated with anti-BCMA CAR-T cells that might have been related to on-target activity in the brain supports prospective neurologic monitoring after BCMA-targeting therapies.
Single-cell transcriptomic analyses of human fetal and neonatal intestinal cells reveal a subpopulation of enteroendocrine cells that produce insulin during development.
The multicenter phase 2 TRIUMPH trial shows the utility of ctDNA genotyping as a screening platform to select patients with HER2-amplified metastatic colorectal cancer who benefit from dual-HER2 blockade with trastuzumab and pertuzumab
Vaccination with BNT162b2 is associated with lower viral load in breakthrough infections of SARS-CoV-2, but this effect wanes at 2 months and vanishes at 6 months after vaccination. A third vaccine dose—or booster—restores the reduction in viral load.
This case report describes a biomarker-driven closed-loop therapy for depression using implanted electrodes to continually sense brain activity and automatically trigger direct brain electrical stimulation in high-depression states.
In an observational cohort of pregnant women in Israel, the BNT162b2 COVID-19 vaccine was found to have effectiveness similar to that seen in the general population.
In healthy adults, booster vaccination with an mRNA vaccine, irrespective of the vaccine used for the first dose, was well tolerated and elicited higher levels of spike-specific antibodies and spike-specific T cells than booster vaccination with ChAdOx1 nCov-19.
