Published: August 2021

AbstractIntroductionThis study examines suicidal ideation and behavior of youth in the 3 months following their initial diversion appointment in the juvenile justice system.MethodParticipants were 99 adolescents (72.7% female; 65% racial minority) between the ages of 12 and 18 (Mage = 15.06, SD = 1.35) and a parent/caregiver (80% female; 54% racial minority; Mage = 42.7 years, SD = 8.9 years). Participants were eligible if they endorsed two or more suicide items on a mental health screener (MAYSI‐2) and were able to be contacted 3 months following initial court appointment. Youth and parent/caregiver responded to questionnaires assessing SI/SA, psychiatric symptoms, treatment motivation and engagement.ResultsThree months post‐initial court appointment, more than half of youth (55.5%) continued to flag on the Suicide Ideation subscale of the MAYSI‐2, though mean scores decreased from baseline to 3‐months (t[97] = 5.74, p < 0.000, 95% CI [−0.79, 1.62] Cohen's d = 0.77). There were no significant differences in parent/youth treatment motivation or engagement regardless of SI at 3 months.ConclusionsPersistence of suicidal thoughts and behaviors beyond initial legal involvement highlights the importance of targeted suicide prevention interventions (beyond screening and referral to treatment) with justice‐involved youth, even at first court contact.

SUMMARYOryza sativa (rice) plays an essential food security role for more than half of the world’s population. Obtaining crops with high levels of disease resistance is a major challenge for breeders, especially today, given the urgent need for agriculture to be more sustainable. Plant resistance genes are mainly encoded by three large leucine‐rich repeat (LRR)‐containing receptor (LRR‐CR) families: the LRR‐receptor‐like kinase (LRR‐RLK), LRR‐receptor‐like protein (LRR‐RLP) and nucleotide‐binding LRR receptor (NLR). Using lrrprofiler, a pipeline that we developed to annotate and classify these proteins, we compared three publicly available annotations of the rice Nipponbare reference genome. The extended discrepancies that we observed for LRR‐CR gene models led us to perform an in‐depth manual curation of their annotations while paying special attention to nonsense mutations. We then transferred this manually curated annotation to Kitaake, a cultivar that is closely related to Nipponbare, using an optimized strategy. Here, we discuss the breakthrough achieved by manual curation when comparing genomes and, in addition to ‘functional’ and ‘structural’ annotations, we propose that the community adopts this approach, which we call ‘comprehensive’ annotation. The resulting data are crucial for further studies on the natural variability and evolution of LRR‐CR genes in order to promote their use in breeding future resilient varieties.
How Structural Features of a Spring-Based Model of Fibrous Collagen Tissue Govern the Overall Young's Modulus

Published: August 2021

Abstract
While much study has been dedicated to investigating biopolymers' stress–strain response at low strain levels, little research has been done to investigate the almost linear region of biopolymers' stress–strain response and how the microstructure affects it. We propose a mathematical model of fibrous networks, which reproduces qualitative features of collagen gel's stress–strain response and provides insight into the key features which impact the Young's modulus of similar fibrous tissues. This model analyzes the relationship of the Young's modulus of the lattice to internodal fiber length, number of connection points or nodes per unit area, and average number of connections to each node. Our results show that fiber length, nodal density, and level of connectivity each uniquely impact the Young's modulus of the lattice. Furthermore, our model indicates that the Young's modulus of a lattice can be estimated using the effective resistance of the network, a graph theory technique that measures distances across a network. Our model thus provides insight into how the organization of fibers in a biopolymer impact its Young's modulus.

Published: August 2021

Abstract
In the present research, a digital twin of coaxial one-side resistance spot welding (COS-RSW) was established for the real-time prediction of transient temperature field. A three-dimensional (3D) model of COS-RSW joint was developed based on the in-house finite element (FE) code JWRIAN-SPOT. The experimental verified FE model was employed to generate the big data of temperature of COS-RSW process. Multiple dimension interpolation was applied to process database and output prediction. The FE model can predict the thermal cycle on COS-RSW joints under different parameter couples. The interpolation effect of individual welding parameters was discussed, and a power weight judgement for welding time was essential to ensure accuracy. With the support of big data, the digital twin can provide visualization prediction of COS-RSW within 10 s, whereas numerical modeling needs at least 1 h. The proposed application of digital twin has potential to improve the efficiency of process optimization in engineering.
Pulsed volcanism and rapid oceanic deoxygenation during Oceanic Anoxic Event 1a

Abstract
Widespread oceanic anoxia, biological crises, and volcanic activity are associated with the onset of Early Aptian (ca. 120 Ma) Oceanic Anoxic Event 1a (OAE1a). Reconstructions of oceanic deoxygenation and its links to broadly contemporaneous volcanism, however, remain poorly resolved. We use geochemical data, including δ53Cr ratios and rare Earth element abundances, to define the timing and tempo of submarine volcanism and global oceanic deoxygenation across this event. Pacific Ocean sediments deposited in the run up to OAE1a record multiple phases of marine volcanism associated with the emplacement of Ontong Java Plateau lavas. Rapid oceanic deoxygenation followed the initial phases of volcanism and a biocalcification crisis. Large swaths of the oceans likely became anoxic from the Tethys to the Pacific Oceans in &lt;30 k.y. Oceanic anoxia persisted for almost one million years after this and was likely sustained through intensified continental and submarine weathering. These results paint a new picture of OAE1a in which volcanism, biological crisis, and oceanic deoxygenation are separated in time and linked through Earth system responses that operate on time scales of tens of thousands of years.
Spontaneous reheating of crystallizing lava
Authors: Whittington Alan G. , Sehlke Alexander 
Published: August 2021

Abstract
We show that recalescence, or spontaneous reheating of a cooling material due to rapid release of latent heat, can occur during disequilibrium crystallization of depolymerized Mg-rich melts. This can only happen at fast cooling rates, where the melt becomes undercooled by tens to hundreds of degrees before crystallization begins. Using a forward-looking infrared (FLIR) camera, we documented recalescence in pyroxene (Fe, Mg)SiO3 and komatiite lavas that initially cooled at 25–50 °C s–1. Local heating at the crystallization front exceeds 150 °C for the pyroxene and 10 °C for komatiite and lasts for several seconds as the crystallization front migrates through. We determined the latent heat release by differential scanning calorimetry to be 440 J g–1 for pyroxene and 275 J g–1 for komatiite with a brief power output of ∼100 W g–1 or ∼300 MW m–3. Recalescence may be a widespread process in the solar system, particularly in lava fountains, and cooling histories of mafic pyroclasts should not be assumed a priori to be monotonic.
The impact of postdepositional alteration on iron- and molybdenum-based redox proxies

Published: August 2021

Abstract
Ratios of (un)reactive iron species, authigenic molybdenum contents (Moauth), and molybdenum isotope compositions (δ98Moauth) in sedimentary rocks are geochemical proxies that are widely used to reconstruct past marine redox states, which have been calibrated in modern marine settings covering oxic to euxinic conditions. However, syn- and postdepositional processes can result in alterations and ambiguities of proxy-derived redox signals that can challenge the validity of paleoreconstructions. We present new data from modern organic-rich sediments of two oxygen minimum zone settings in the Gulf of California and the Peruvian margin. The results show that Mo is fully immobilized shortly after deposition by reaction with hydrogen sulfide (H2S) produced during organoclastic sulfate reduction. Thus, any H2S produced deeper in the sediment (e.g., by sulfate reduction coupled to anaerobic methane oxidation) leaves the initially deposited Mo concentrations and δ98Mo signatures unaltered, which supports the robustness of Mo-based redox proxies. In contrast, the Fe speciation data reveal continued pyritization due to constant exposure of Fe minerals to H2S. Importantly, both Fe bound to oxides and carbonates (highly reactive Fe) and also poorly reactive Fe (e.g., sheet silicates) undergo pyritization during early diagenesis. This process generates Fe-based proxy signatures that falsely imply ferruginous or euxinic conditions.

IntroductionCOVID-19 pandemic has an impact on mortality indicators worldwide. Mitigation and repression actions to reduce the morbidity and mortality associated with the disease are necessary. However, they are criticised in the economic, social and psychological spheres. This social isolation, increased unemployment, routine changes, news of health complications and deaths related to COVID-19 can cause psychological repercussions that will certainly intensify in the coming months, and suicidal behaviour presents itself as a fatal outcome. It is necessary to know factors associated with suicidal behaviour in adults during the pandemic. Although there are studies, there is no systematic review to assess these factors, specifically in adults. The objective is to critically synthesise the scientific evidence on the factors associated with suicidal behaviour in adults in the COVID-19 pandemic.Methods and analysesA systematic review will be carried out, recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, in seven databases: Medical Literature Analysis and Retrieval System Online (MEDLINE), ISI of Knowledge, Excerpta Medica Database (EMBASE), SCOPUS, Latin American and Caribbean Health Sciences Literature (LILACS), Chinese National Knowledge Infrastructure (PsycINFO), Chinese National Knowledge Infrastructure (CNKI) and ScienceDirect. Preliminary search was carried out on 30 July 2020 and will be updated in March 2021. No restrictions on publication date, study location or languages will be considered in this review. The preliminary research strategies were carried out on 30 July 2020 and will be updated in February 2021. To measure the agreement between reviewers at each screening stage, Cohen’s Kappa will be calculated. Primary outcome will be factors related to suicidal behaviour in adults during COVID-19 pandemic. Grouped standardised mean differences and 95% CIs will be calculated. The risk of bias in observational studies will be assessed using the Methodological Index for Non-Randomised Studies (MINORS). Statistical heterogeneity will be assessed with the I2 statistic.Ethics and disclosureEthical approval is not required, as primary data will not be collected. The findings will be disseminated through peer-reviewed publications.PROSPERO registration numberCRD42020208816.

Published: August 2021

ObjectivesMeasuring staff perspectives on patient safety culture (PSC) can identify areas of concern that, if addressed, could lead to improvements in healthcare. To date, there is no validated measure to assess PSC that has been tested and adapted for use in Bosnia and Herzegovina (BiH). This research addresses the gap in the evidence through the psychometric assessment of the Agency for Healthcare Research and Quality’s: ‘Hospital Survey on Patient Safety Culture’ (HSOPSC), to determine its suitability for the health system in BiH.SettingNine hospitals.ParticipantsHealthcare professionals (n=1429); nurse (n=823), doctors (n=328), other clinical personnel (n=111), non-clinical personnel (n=60), other (n=64), no response (n=43).Primary and secondary outcome measuresA translated version of HSOPSC was used to conduct psychometric evaluation including exploratory factor analysis and confirmatory factor analysis (CFA). Comparison between the original HSOPSC and the newly adapted ‘Hospital Survey on Patient Safety Culture for Bosnia and Herzegovina’ (HSOPSC-BiH) was carried out.ResultsCompared with the original survey, which has 12 factors (42 items), the adapted survey consisted of 9 factors (29 items). The following factors from the original survey were not included in their original form: Communication Openness, Feedback and Communications about error, Overall Perceptions of Patient Safety and Organisational learning—Continuous Improvement. The results of the CFA for HSOPSC-BiH showed a better model fit compared with the original HSOPSC. The absolute and relative fit indices showed excellent model adjustment.ConclusionsThe BiH version of Hospital Survey on Patient Safety Culture demonstrated satisfactory psychometric properties, with acceptable to good internal consistency and construct validity. Therefore, we recommend the HSOPSC-BiH as a basis for assessing PSC in BiH. This survey could provide insight into patient safety concerns in BiH so that strategies to overcome these issues could be formulated and implemented.

Published: August 2021

IntroductionDespite a long-term downward trend in smoking prevalence, tobacco remains the number one risk factor for death and disability in Sweden. Globally, tobacco use generates a substantial economic burden for health systems and is also a major driver of socioeconomic inequalities in health. This article describes the planned cost-effectiveness and health equity impact evaluation of a multicomponent school-based programme to prevent the onset of tobacco use in adolescents.Methods and analysisCost-effectiveness of the multicomponent Tobacco-Free Duo programme will be evaluated against the educational component of the same programme only. An incremental cost-effectiveness ratio (ICER) will be calculated in terms of the cost per case prevented using the trial primary outcome and within-trial payer costs. If the ICER is negative, an incremental net benefit ratio will be calculated. Robustness of the results will be assessed through one-way sensitivity analyses. The slope index of inequality will be computed to assess the potential impact of the Tobacco-free Duo programme on education-related inequalities in the onset of smoking and in adult smoking cessation, comparing the two trial arms.Ethics and disseminationEthical approval was obtained from the Regional Ethics Review Board, Umeå (registration number 2017/255-31). The Public Health Agency of Sweden commissioned the study. The findings will be disseminated internationally within academia and to national and local policy-makers.Trial registration numberISRCTN52858080; Pre-results.

ObjectivesAlthough spontaneous breathing trials (SBTs) are standard of care to extubation readiness, no tool exists that optimises prediction and standardises assessment. In this study, we evaluated the feasibility and clinical impressions of Extubation Advisor (EA), a comprehensive clinical extubation decision support (CDS) tool.DesignPhase I mixed-methods observational study.SettingTwo Canadian intensive care units (ICUs).ParticipantsWe included patients on mechanical ventilation for ≥24 hours and clinicians (respiratory therapists and intensivists) responsible for extubation decisions.InterventionsComponents included a predictive model assessment, feasibility evaluation, questionnaires and interviews with clinicians.ResultsWe enrolled 117 patients, totalling 151 SBTs and 80 extubations. The incidence of extubation failure was 11% in low-risk patients and 21% in high-risk patients stratified by the predictive model; 38% failed extubation when both the model and clinical impression were at high risk. The tool was well rated: 94% and 75% rated the data entry and EA report as average or better, respectively. Interviews (n=15) revealed favourable impressions regarding its user interface and functionality, but unexpectedly, also concerns regarding EA’s potential impact on respiratory therapists’ job security.ConclusionsEA implementation was feasible, and users perceived it to have potential to support extubation decision-making. This study helps to understand bedside implementation of CDS tools in a multidisciplinary ICU.Trial registration numberNCT02988167.
Implications of a travel connectivity-based approach for infectious disease transmission risks in Oceania

Published: August 2021

IntroductionThe increase in international travel brought about by globalisation has enabled the rapid spread of emerging pathogens with epidemic and pandemic potential. While travel connectivity-based assessments may help understand patterns of travel network-mediated epidemics, such approaches are rarely carried out in sufficient detail for Oceania where air travel is the dominant method of transportation between countries.DesignTravel data from the Australian Bureau of Statistics, Stats NZ and the United Nations World Tourism Organization websites were used to calculate travel volumes in 2018 within Oceania and between Oceania and the rest of the world. The Infectious Disease Vulnerability Index (IDVI) was incorporated into the analysis as an indicator of each country’s capacity to contain an outbreak. Travel networks were developed to assess the spread of infectious diseases (1) into and from Oceania, (2) within Oceania and (3) between each of the Pacific Island Countries and Territories (PICTs) and their most connected countries.ResultsOceania was highly connected to countries in Asia, Europe and North America. Australia, New Zealand and several PICTs were highly connected to the USA and the UK (least vulnerable countries for outbreaks based on the IDVI), and to China (intermediate low vulnerable country). High variability was also observed between the PICTs in the geographical distribution of their international connections. The PICTs with the highest number of international connections were Fiji, French Polynesia, Guam and Papua New Guinea.ConclusionTravel connectivity assessments may help to accurately stratify the risk of infectious disease importation and outbreaks in countries depending on disease transmission in other parts of the world. This information is essential to track future requirements for scaling up and targeting outbreak surveillance and control strategies in Oceania.

BackgroundAfter stroke, many patients experience cognitive and/or emotional problems. While national guidelines recommend screening for these problems, actual screening rates might be limited.ObjectiveThis study aimed to examine the clinical practice at neurology departments regarding screening, information provision and follow-up care for cognitive and emotional problems after transient ischaemic attack (TIA) and ischaemic stroke.MethodsA nationwide, cross-sectional, online survey was conducted between October 2018 and October 2019 among neurologists in all hospitals in the Netherlands.ResultsNeurologists in 78 hospitals were invited to join the survey, and 52 (67%) of them completed it. Thirty-one (59%) neurologists reported that screening for cognitive problems after TIA and ischaemic stroke was mostly or always performed. When cognitive screening was performed, 42 (84%) used validated screening instruments. Twenty-nine (56%) of the respondents reported that screening for emotional problems was mostly or always performed. When emotional screening was performed, 31 (63%) reported using validated screening instruments. Timing of screening and information provision was highly variable, and the majority reported that there was no protocol for follow-up care when cognitive or emotional problems were found.ConclusionsThis study demonstrates that clinical practice at neurology departments is highly variable regarding screening, information provision and follow-up care for cognitive and emotional problems in patients after TIA or ischaemic stroke. Approximately half of the participating neurologists reported that screening was performed only sometimes or never for cognitive and emotional problems after TIA and ischaemic stroke.
