Published: December 2021

AbstractBackgroundAgriculture is one of the most hazardous occupations in the USA. Especially, tractor rollover incidents are the leading cause of farming-related injuries or deaths. This study examines the effect of a VR intervention (Virtual Reality Intervention for Safety Education; VRISE) on behavioral intentions for occupational safety and identifies a psychological mechanism that shows how the immersive technology works.MethodsVRISE was developed by a multidisciplinary team of agricultural educators, computer scientists and communication specialists. It was designed to provide a virtual environment where users practice tractor operation and try to avoid several rollover hazards. The participants (291 high school students) were recruited at the 2019 National Future Farmers Association Convention & Expo and randomly assigned to one of three conditions: two different types of control groups (Control1: No treatment group and Control2: 2D Screen group) and the treatment group.ResultsFindings show that, through the immersive VR experience, the VR intervention enhanced perceived threat of tractor-related accidents which in turn, led to improved behavioral intentions for tractor safety.ConclusionsFindings shed light on the effectiveness of a VR intervention to improve public health outcomes, especially in occupational safety education, where unsafe practices often result in injury and fatality.
Marginal Effects of Merit Aid for Low-Income Students

Published: December 2021

Abstract
Financial aid from the Susan Thompson Buffett Foundation (STBF) provides comprehensive support to a student population similar to that served by a host of state aid programs. In conjunction with STBF, we randomly assigned aid awards to thousands of Nebraska high school graduates from low-income, minority, and first-generation college households. Randomly assigned STBF awards boost bachelor’s (BA) degree completion for students targeting four-year schools by about 8 points. Degree gains are concentrated among four-year college applicants who would otherwise have been unlikely to pursue a four-year program. Degree effects are mediated by award-induced increases in credits earned toward a BA in the first year of college. The extent of initial four-year college engagement explains differences in impact by target campus and across covariate subgroups. The projected lifetime earnings effect of awards exceeds marginal educational spending for all of the subgroups examined in the study. Projected earnings gains exceed funder costs for urban students and for students with relatively weak academic preparation.

Abstract

Objective
To better understand rheumatology patient and clinician pandemic-related experiences, medical relationships and behaviours in order to help identify the persisting impacts of the COVID-19 pandemic and inform efforts to ameliorate the negative impacts and build upon the positive ones.

Methods
Rheumatology patients and clinicians completed surveys (patients n = 1543, clinicians n = 111) and interviews (patients n = 41, clinicians n = 32) between April 2021 and August 2021. A cohort (n = 139) of systemic autoimmune rheumatic disease patients was also followed up from March 2020 to April 2021. Analyses used sequential mixed methods. Pre-specified outcome measures included the Warwick–Edinburgh Mental wellbeing score (WEMWBS), satisfaction with care and healthcare behaviours.

Results
We identified multiple ongoing pandemic-induced/increased barriers to receiving care. The percentage of patients agreeing they were medically supported reduced from 74.4% pre-pandemic to 39.7% during-pandemic. Ratings for medical support, medical security and trust were significantly (P &lt;0.001) positively correlated with patient WEMWBS and healthcare behaviours, and decreased during the pandemic. Healthcare-seeking was reduced, potentially long-term, including from patients feeling ‘abandoned’ by clinicians, and a ‘burden’ from government messaging to protect the NHS. Blame and distrust were frequent, particularly between primary and secondary care, and towards the UK government, who &lt;10% of clinicians felt had supported clinicians during the pandemic. Clinicians’ efforts were reported to be impeded by inefficient administration systems and chronic understaffing, suggestive of the pandemic having exposed and exacerbated existing healthcare system weaknesses.

Conclusion
Without concerted action—such as rebuilding trust, improved administrative systems and more support for clinicians—barriers to care and negative impacts of the pandemic on trust, medical relationships, medical security and patient help-seeking may persist in the longer term.

Trial registration
This study is part of a pre-registered longitudinal multi-stage trial, the LISTEN study (ISRCTN-14966097), with later COVID-related additions registered in March 2021, including a pre-registered statistical analysis plan.

AbstractIn the human genome, about 750 genes contain one intron excised by the minor spliceosome. This spliceosome comprises its own set of snRNAs, among which U4atac. Its non-coding gene,RNU4ATAC, has been found mutated in Taybi-Linder (MOPD1/TALS), Roifman (RFMN) and Lowry-Wood syndromes (LWS). These rare developmental disorders, whose physiopathological mechanisms remain unsolved, associate ante- and post-natal growth retardation, microcephaly, skeletal dysplasia, intellectual disability, retinal dystrophy and immunodeficiency. Here, we report a homozygousRNU4ATACmutation in the Stem II domain, n.16G>A, in two unrelated patients presenting with both typical traits of the Joubert syndrome (JBTS), a well-characterized ciliopathy, and of TALS/RFMN/LWS, thus widening the clinical spectrum ofRNU4ATAC-associated disorders and indicating ciliary dysfunction as a mechanism downstream of minor splicing defects. This finding is supported by alterations of primary cilium function in TALS and JBTS/RFMN fibroblasts, as well as byu4ataczebrafish model, which exhibit ciliopathy-related phenotypes and ciliary defects. Altogether, our data indicate that alteration of cilium biogenesis is part of the physiopathological mechanisms of TALS/RFMN/LWS, secondarily to defects of minor intron splicing.

SummaryBackgroundAlthough biological agents, tocilizumab and baricitinib, have been shown to improve the outcomes of patients with COVID-19, a comparative evaluation has not been performed.MethodsA retrospective, single-center study was conducted using the data of patients with COVID-19 admitted to the Hokkaido University hospital between April 2020 and September 2021, who were treated with tocilizumab or baricitinib. The clinical characteristics of patients who received each drug were compared. Univariate and multivariate logistic regression models were performed against the outcomes of all-cause mortality and the improvement in respiratory status. The development of secondary infection events was analyzed using the Kaplan–Meier analysis and the log-rank test.ResultsThe use of tocilizumab or baricitinib was not associated with all-cause mortality and the improvement in respiratory status within 28 days of drug administration. Age, chronic renal disease, and comorbid respiratory disease were independent prognostic factors for all-cause mortality, while anti-viral drug use and severity of COVID-19 at baseline were associated with the improvement in respiratory status. There was no significant difference in the infection-free survival between patients treated with tocilizumab and those with baricitinib.ConclusionThere were no differences in efficacy and safety between tocilizumab and baricitinib for the treatment of COVID-19.

AbstractMotivated by the potential of objective neurophysiological markers to index thalamocortical function in patients with severe psychiatric illnesses, we comprehensively characterized key NREM sleep parameters across multiple domains, their interdependencies, and their relationship to waking event-related potentials and symptom severity. In 130 schizophrenia (SCZ) patients and controls, we confirmed a marked reduction in sleep spindle density in SCZ and extended these findings to show that only slow spindles predicted symptom severity, and that fast and slow spindle properties were largely uncorrelated. We also describe a novel measure of slow oscillation and spindle interaction that was attenuated in SCZ. The main sleep findings were replicated in a demographically distinct sample, and a joint model, based on multiple NREM components, predicted disease status in the replication cohort. Although also altered in patients, auditory event-related potentials elicited during wake were unrelated to NREM metrics. Consistent with a growing literature implicating thalamocortical dysfunction in SCZ, our characterization identifies independent NREM and wake EEG biomarkers that may index distinct aspects of SCZ pathophysiology and point to multiple neural mechanisms underlying disease heterogeneity. This study lays the groundwork for evaluating these neurophysiological markers, individually or in combination, to guide efforts at treatment and prevention as well as identifying individuals most likely to benefit from specific interventions.
Effect of Light Conditions onIn VitroAdventitious Organogenesis of Cucumber Cultivars
Authors: Miguel Jorge Fonseca 
Published: December 2021

AbstractThe response on callus and shoot formation under different light incubation conditions was evaluated in cucumber (Cucumis sativusL.). Four-day-old cotyledon explants from the inbred line ‘Wisconsin 2843’ and the commercial cultivars ‘Marketer’ and ‘Negrito’ were employed. A four-week culture was conducted on MS-derived shoot induction medium containing 0.5 mg L-1 IAA and 2.5 mg L-1 BAP, under an 8-h dark/ 16-h light regime, or by a one- or two-week dark pre-incubation followed by the same photoperiod. Significant differences were obtained for the regeneration of shoots in all cultivars. The response in both frequency and number of shoots under continuous photoperiod was at least 3-6 fold higher than with dark pre-incubation. The highest genotypes response was obtained by ‘Negrito’ and ‘Marketer’ with identical values. All explants formed callus, and in two of the three cultivars, the response on callus extension was not significantly affected by incubation conditions. The results clearly show that shoot induction under continuous photoperiod regime was beneficial for adventitious shoot regeneration in cucumber.

Published: December 2021

AbstractVaccination against viruses has rarely been associated with Guillain-Barré syndrome (GBS). An association with the COVID-19 vaccine is unknown. We performed a population-based study of National Health Service data in England and a multicentre surveillance study from UK hospitals, to investigate the relationship between COVID-19 vaccination and GBS.Firstly, case dates of GBS identified retrospectively in the National Immunoglobulin Database from 8 December 2021 to 8 July 2021 were linked to receipt dates of a COVID-19 vaccines using data from the National Immunisation Management System in England. For the linked dataset, GBS cases temporally associated with vaccination within a 6-week risk window of any COVID-19 vaccine were identified. Secondly, we prospectively collected incident UK-wide (four nations) GBS cases from 1 January 2021 to 7 November 2021 in a separate UK multicentre surveillance database. For this multicentre UK-wide surveillance dataset, we explored phenotypes of reported GBS cases to identify features of COVID-19 vaccine-associated GBS.996 GBS cases were recorded in the National Immunoglobulin Database from January to October 2021. A spike of GBS cases above the 2016-2020 average occurred in March-April 2021. 198 GBS cases occurred within 6 weeks of the first-dose COVID-19 vaccination in England (0.618 cases per 100,000 vaccinations, 176 ChAdOx1 nCoV-19 (AstraZeneca), 21 tozinameran (Pfizer), 1 mRNA-1273 (Moderna)). The 6-week excess of GBS (compared to the baseline rate of GBS cases 6-12 weeks after vaccination) occurs with a peak at 24 days post-vaccination; first-doses of ChAdOx1 nCoV-19 accounted for the excess. No excess was seen for second-dose vaccination. The absolute number of excess GBS cases from January-July 2021 was between 98-140 cases for first-dose ChAdOx1 nCoV-19 vaccination. First-dose tozinameran and second-dose of any vaccination showed no excess GBS risk. Detailed clinical data from 121 GBS patients were reported in the separate multicentre surveillance dataset during this timeframe. No phenotypic or demographic differences identified between vaccine-associated and non-vaccinated GBS cases occurring in the same timeframe.Analysis of the linked NID/NIMS dataset suggests that first-dose ChAdOx1 nCoV-19 vaccination is associated with an excess GBS risk of 0.576 (95%CI 0.481-0.691) cases per 100,000 doses. However, examination of a multicentre surveillance dataset suggests that no specific clinical features, including facial weakness, are associated with vaccination-related GBS compared to non-vaccinated cases. The pathogenic cause of the ChAdOx1 nCoV-19 specific first dose link warrants further study.

AbstractBackgroundWorkers differ in their risk of SARS-CoV-2 infection according to their occupation, but the direct contribution of occupation to this relationship is unclear. This study aimed to investigate how infection risk differed across occupational groups in England and Wales up to April 2022, after adjustment for potential confounding and stratification by pandemic phase.MethodsData from 15,190 employed/self-employed participants in the Virus Watch prospective cohort study were used to generate risk ratios for virologically- or serologically-confirmed SARS-CoV-2 infection using robust Poisson regression, adjusting for socio-demographic and health-related factors and non-work public activities. We calculated attributable fractions (AF) amongst the exposed for belonging to each occupational group based on adjusted risk ratios (aRR).FindingsIncreased risk was seen in nurses (aRR=1.44, 1.25-1.65; AF=30%, 20-39%), doctors (aRR=1.33, 1.08-1.65; AF=25%, 7-39%), carers (1.45, 1.19-1.76; AF=31%, 16-43%), primary school teachers (aRR=1.67, 1.42-1.96; AF=40%, 30-49%), secondary school teachers (aRR=1.48, 1.26-1.72; AF=32%, 21-42%), and teaching support occupations (aRR=1.42, 1.23-1.64; AF=29%, 18-39%) compared to office-based professional occupations. Differential risk was apparent in the earlier phases (Feb 2020 - May 2021) and attenuated later (June - October 2021) for most groups, although teachers and teaching support workers demonstrated persistently elevated risk across waves.InterpretationOccupational differentials in SARS-CoV-2 infection risk vary over time and are robust to adjustment for socio-demographic, health-related, and non-workplace activity-related potential confounders. Direct investigation into workplace factors underlying elevated risk and how these change over time is needed to inform occupational health interventions.

ABSTRACTBackgroundSodium reduction lowers blood pressure and albuminuria, indicating a hypothesized but yet-to-be proven association between sodium intake and kidney-related endpoints.ObjectivesWe aimed to investigate the associations of 24-h urinary sodium excretion, reflecting daily sodium intake, with kidney-related outcomes.MethodsProspective cohort of 444,086 middle- to early late-aged participants from the UK Biobank. The primary outcome was a composite of incident end-stage kidney disease (ESKD) and death due to a kidney-related cause, each of which was separately examined as a secondary outcome. Death due to a non-kidney related cause prior to ESKD was considered a competing event.ResultsThe mean 24-h urinary sodium excretion estimated from spot urinary biomarkers was 3.3 g. During a median follow-up of 11.8 years, 1,256 composite events occurred. Multivariable-adjusted cause-specific hazards models showed that, with every 1-g increment in 24-h urinary sodium excretion, hazard ratios (95% confidence intervals) were 1.03 (0.91-1.16), 1.08 (0.88-1.32), and 1.01 (0.88-1.16) for the composite outcome, incident ESKD, and kidney-related death, respectively. Similar null results were observed when the exposure was treated as binary (<2 g/d vs. ≥2 g/d) or multicategorical (quartiles). Nonlinear associations were not detected with restricted cubic splines. The findings also held constant in prespecified sensitivity and subgroup analyses.ConclusionsEstimated 24-h urinary sodium excretion was not linearly or nonlinearly associated with the incidence of ESKD or death due to kidney-related causes. Our findings did not support the hypothesized notion that sodium intake should be reduced to prevent kidney-related endpoints at the population level.

AbstractBackgroundThe role of children and young people (CYP) in transmission of SARS-CoV-2 in household and educational settings remains unclear. We undertook a systematic review and meta-analysis of contact-tracing and population-based studies at low risk of bias.MethodsWe searched 4 electronic databases on 28 July 2021 for contact-tracing studies and population-based studies informative about transmission of SARS-CoV-2 from 0-19 year olds in household or educational settings. We excluded studies at high risk of bias, including from under-ascertainment of asymptomatic infections. We undertook multilevel random effects meta-analyses of secondary attack rates (SAR: contact-tracing studies) and school infection prevalence, and used meta-regression to examine the impact of community SARS-CoV-2 incidence on school infection prevalence.Findings4529 abstracts were reviewed, resulting in 37 included studies (16 contact-tracing; 19 population studies; 2 mixed studies). The pooled relative transmissibility of CYP compared with adults was 0.92 (0.68, 1.26) in adjusted household studies. The pooled SAR from CYP was lower (p=0.002) in school studies 0.7% (0.2, 2.7) than household studies (7.6% (3.6, 15.9). There was no difference in SAR from CYP to child or adult contacts. School population studies showed some evidence of clustering in classes within schools. School infection prevalence was associated with contemporary community 14-day incidence (OR 1.003 (1.001, 1.004), p<0.001).InterpretationWe found no difference in transmission of SARS-CoV-2 from CYP compared with adults within household settings. SAR were markedly lower in school compared with household settings, suggesting that household transmission is more important than school transmission in this pandemic. School infection prevalence was associated with community infection incidence, supporting hypotheses that school infections broadly reflect community infections. These findings are important for guiding policy decisions on shielding, vaccination school and operations during the pandemic.FundingNo funding obtained.
