ChAdOx1 nCoV-19 is a recombinant adenovirus vaccine against SARS-CoV-2 that has passed phase III clinical trials and is now in use across the globe. Although replication-defective in normal cells, 28 kbp of adenovirus genes is delivered to the cell nucleus alongside the SARS-CoV-2 S glycoprotein gene. ⋯ Overall, the ChAdOx1 nCoV-19 vaccine's transcriptomic and proteomic repertoire in cell culture is as expected. The combined transcriptomic and proteomics approaches provide a detailed insight into the behaviour of this important class of vaccine using state-of-the-art techniques and illustrate the potential of this technique to inform future viral vaccine vector design.

In randomized trials with subgroup analyses, the primary treatment or intervention of interest is randomized, but the secondary factors defining subgroups are not. This article clarifies when confounding is an issue in subgroup analyses. ⋯ If investigators are interested in intervening on the secondary factors that define the subgroups to increase the treatment effect or in attributing the subgroup differences to the secondary factors themselves, then confounding is relevant and must be controlled for. The authors demonstrate this point by using examples from published randomized trials.

The aim of the study was to investigate the safety and efficacy of using MLT in the treatment of open-angle glaucoma (OAG). This prospective cohort included subjects ≥18 years of age with OAG, defined as the open angle on gonioscopy with glaucomatous optic neuropathy evident from optical coherence tomography. Subjects with IOP < 21 mm Hg were classified as normal tension glaucoma and those with IOP ≥21 mm Hg were classified as primary open-angle glaucoma. ⋯ The MLT success rate was 72.9%. During the first 6 months only 2.1% required a repeated laser trabeculoplasty. MLT was effective in reducing IOP and medications in OAG with minimal postlaser inflammation and low failure rate at 6 months following laser.

Recently, telemedicine has become a widely used method worldwide for the treatment of patients with acute ischemic stroke in hospitals where neurologists are unavailable. The purpose of this study was to determine the accuracy and reliability of treatment decisions made by remote neurologists via teleconference assisted by emergency physicians in acute stroke cases and to determine whether the use of teleconsultation would lead to any delays in assessment and treatment decisions. ⋯ Teleconsultation was a successful and reliable strategy in assessing patients with ischemic stroke and making decisions for IV-tPA. Moreover, patient assessment via teleconsultation was less time consuming. The results of the study are promising for the use of teleconsultation in the future.

We present CoronaHiT, a platform and throughput flexible method for sequencing SARS-CoV-2 genomes (≤ 96 on MinION or > 96 on Illumina NextSeq) depending on changing requirements experienced during the pandemic. CoronaHiT uses transposase-based library preparation of ARTIC PCR products. ⋯ Of the 154 samples sequenced using all 3 methods, ≥ 90% genome coverage was obtained for 64.3% using ARTIC LoCost, 71.4% using CoronaHiT-ONT and 76.6% using CoronaHiT-Illumina, with almost identical clustering on a maximum likelihood tree. This protocol will aid the rapid expansion of SARS-CoV-2 genome sequencing globally.
