Designing a Game to Help Higher Education Students Develop Their Note-Taking Skills

© 2020 Copyright is held by the owner/author(s). Taking effective notes is an important skill in academic and professional settings and one that is cultivated primarily in Higher Education (HE). However, students often find it difficult to effectively record important information in their notes [37], while it has been suggested that they often record less than 50% of the key information of a lecture [15]. Games can be a powerful way to help students learn [30]. Yet, to date, there is scarce empirical research on games specifically designed to help HE students develop note-taking skills where the design has been directly informed by note-taking learning theories. This study applies such theories in the design of the mechanics for an educational game for note-taking, entitled Investigate: Tudors, and evaluates their effectiveness and engaging potential. Results from qualitative evaluations with HE students showed that the game was a successful tool to help them develop note- taking skills. This article discusses the game design approach and the evaluation results, and contributes with effective strategies for designing serious games for note-taking.ACM SIGCHI (Special Interest Group on Computer-Human Interaction

Randomized controlled trial of molnupiravir SARS-CoV-2 viral and antibody response in at-risk adult outpatients

Viral clearance, antibody response and the mutagenic effect of molnupiravir has not been elucidated in at-risk populations. Non-hospitalised participants within 5 days of SARS-CoV-2 symptoms randomised to receive molnupiravir (n = 253) or Usual Care (n = 324) were recruited to study viral and antibody dynamics and the effect of molnupiravir on viral whole genome sequence from 1437 viral genomes. Molnupiravir accelerates viral load decline, but virus is detectable by Day 5 in most cases. At Day 14 (9 days post-treatment), molnupiravir is associated with significantly higher viral persistence and significantly lower anti-SARS-CoV-2 spike antibody titres compared to Usual Care. Serial sequencing reveals increased mutagenesis with molnupiravir treatment. Persistence of detectable viral RNA at Day 14 in the molnupiravir group is associated with higher transition mutations following treatment cessation. Viral viability at Day 14 is similar in both groups with post-molnupiravir treated samples cultured up to 9 days post cessation of treatment. The current 5-day molnupiravir course is too short. Longer courses should be tested to reduce the risk of potentially transmissible molnupiravir-mutated variants being generated. Trial registration: ISRCTN30448031

Investigation of hospital discharge cases and SARS-CoV-2 introduction into Lothian care homes

Background The first epidemic wave of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in Scotland resulted in high case numbers and mortality in care homes. In Lothian, over one-third of care homes reported an outbreak, while there was limited testing of hospital patients discharged to care homes. Aim To investigate patients discharged from hospitals as a source of SARS-CoV-2 introduction into care homes during the first epidemic wave. Methods A clinical review was performed for all patients discharges from hospitals to care homes from 1st March 2020 to 31st May 2020. Episodes were ruled out based on coronavirus disease 2019 (COVID-19) test history, clinical assessment at discharge, whole-genome sequencing (WGS) data and an infectious period of 14 days. Clinical samples were processed for WGS, and consensus genomes generated were used for analysis using Cluster Investigation and Virus Epidemiological Tool software. Patient timelines were obtained using electronic hospital records. Findings In total, 787 patients discharged from hospitals to care homes were identified. Of these, 776 (99%) were ruled out for subsequent introduction of SARS-CoV-2 into care homes. However, for 10 episodes, the results were inconclusive as there was low genomic diversity in consensus genomes or no sequencing data were available. Only one discharge episode had a genomic, time and location link to positive cases during hospital admission, leading to 10 positive cases in their care home. Conclusion The majority of patients discharged from hospitals were ruled out for introduction of SARS-CoV-2 into care homes, highlighting the importance of screening all new admissions when faced with a novel emerging virus and no available vaccine

SARS-CoV-2 Omicron is an immune escape variant with an altered cell entry pathway

Vaccines based on the spike protein of SARS-CoV-2 are a cornerstone of the public health response to COVID-19. The emergence of hypermutated, increasingly transmissible variants of concern (VOCs) threaten this strategy. Omicron (B.1.1.529), the fifth VOC to be described, harbours multiple amino acid mutations in spike, half of which lie within the receptor-binding domain. Here we demonstrate substantial evasion of neutralization by Omicron BA.1 and BA.2 variants in vitro using sera from individuals vaccinated with ChAdOx1, BNT162b2 and mRNA-1273. These data were mirrored by a substantial reduction in real-world vaccine effectiveness that was partially restored by booster vaccination. The Omicron variants BA.1 and BA.2 did not induce cell syncytia in vitro and favoured a TMPRSS2-independent endosomal entry pathway, these phenotypes mapping to distinct regions of the spike protein. Impaired cell fusion was determined by the receptor-binding domain, while endosomal entry mapped to the S2 domain. Such marked changes in antigenicity and replicative biology may underlie the rapid global spread and altered pathogenicity of the Omicron variant

The genetic background modifies the spontaneous and X-ray-induced tumor spectrum in the Apc1638N mouse model

The effect of the genetic background on the tumor spectrum of Apc1638N, a mouse model for attenuated familial adenomatous polyposis (FAP), has been investigated in X-irradiated and untreated F1 hybrids between C57BL/6JIco- Apc1638N (B6) and A/JCrIBR (A/J), BALB/cByJIco (C) or C3H/HeOuJIco (C3). Similar to the Apc(Min) model, the Apc1638N intestinal tumor multiplicity seems to be modulated by Mom1. Moreover, several additional (X-ray- responsive) modifier loci appear also to affect the Apc1638N intestinal tumor number. The genetic background did not significantly influence the number of spontaneous desmoids and cutaneous cysts in Apc1638N. In general, X- irradiation increased the desmoid multiplicity in Apc1638N females but had no effect in males. The opposite was noted for the cyst multiplicity after X- rays. Surprisingly, X-irradiated CB6F1-Apc1638N females were highly susceptible to the development of ovarian tumors, which displayed clear loss of the wild-type Apc allele
