RESUMO
We report an update of the Hymenoptera Genome Database (HGD; http://HymenopteraGenome.org), a genomic database of hymenopteran insect species. The number of species represented in HGD has nearly tripled, with fifty-eight hymenopteran species, including twenty bees, twenty-three ants, eleven wasps and four sawflies. With a reorganized website, HGD continues to provide the HymenopteraMine genomic data mining warehouse and JBrowse/Apollo genome browsers integrated with BLAST. We have computed Gene Ontology (GO) annotations for all species, greatly enhancing the GO annotation data gathered from UniProt with more than a ten-fold increase in the number of GO-annotated genes. We have also generated orthology datasets that encompass all HGD species and provide orthologue clusters for fourteen taxonomic groups. The new GO annotation and orthology data are available for searching in HymenopteraMine, and as bulk file downloads.

Current genome sequencing technologies have made it possible to generate highly contiguous genome assemblies for non-model animal species. Despite advances in genome assembly methods, there is still room for improvement in the delineation of specific gene features in the genomes. Here we present genome visualization and annotation tools to support seven livestock species (bovine, chicken, goat, horse, pig, sheep, and water buffalo), available in a new resource called AgAnimalGenomes. In addition to supporting the manual refinement of gene models, these browsers provide visualization tracks for hundreds of RNAseq experiments, as well as data generated by the Functional Annotation of Animal Genomes (FAANG) Consortium. For species with predicted gene sets from both Ensembl and RefSeq, the browsers provide special tracks showing the thousands of protein-coding genes that disagree across the two gene sources, serving as a valuable resource to alert researchers to gene model issues that may affect data interpretation. We describe the data and search methods available in the new genome browsers and how to use the provided tools to edit and create new gene models.

INTRODUCTION: Mild cognitive impairment remains substantially underdiagnosed, especially in disadvantaged populations. Failure to diagnose deprives patients and families of the opportunity to treat reversible causes, make necessary life and lifestyle changes and receive disease-modifying treatments if caused by Alzheimer's disease. Primary care, as the entry point for most, plays a critical role in improving detection rates. METHODS: We convened a Work Group of national experts to develop consensus recommendations for policymakers and third-party payers on ways to increase the use of brief cognitive assessments (BCAs) in primary care. RESULTS: The group recommended three strategies to promote routine use of BCAs: providing primary care clinicians with suitable assessment tools; integrating BCAs into routine workflows; and crafting payment policies to encourage adoption of BCAs. DISSCUSSION: Sweeping changes and actions of multiple stakeholders are necessary to improve detection rates of mild cognitive impairment so that patients and families may benefit from timely interventions.

Maternal grandmothers play a vital role in the transition to motherhood for their own daughters. The current study adds to this literature by investigating the lived experience of motherhood for women who lacked a meaningful relationship with their mothers. Ten mothers of children under 2 years of age participated in a semi-structured interview to explore their lived experiences of being a mother. Women were recruited from two parent-infant services in Northern Ireland. The interviews were analyzed using Interpretive Phenomenological Analysis (IPA). Three superordinate themes were identified: 'The Birth of a Mother', 'Mourning and Loss' and 'Ghosts in the Nursery'. The first theme captured the significant change of identity women experienced during their transition to motherhood. This identity change shed new light on their own experience of being mothered. The second theme captured the mourning and loss these women felt due to their relationship with their mother. Their lack of meaningful maternal relationships have left a hole impossible to fill. The final theme spoke to the intergenerational element of these mother's experience and their desire to break a cycle of maternal deprivation. The rich content from the interviews highlights the need for services to be aware of this struggle of motherhood.
Las abuelas maternas juegan un papel vital en la transición a la maternidad para sus propias hijas. El presente estudio contribuye a este campo de conocimientos escritos por medio de investigar la experiencia de maternidad vividas por mujeres a quienes les hace falta una significativa relación con sus madres. Diez madres de niños menores de dos años de edad participaron en una entrevista semiestructurada para explorar sus vividas experiencias de ser madre. A las mujeres se les reclutó de dos servicios progenitor-infante en Irlanda del Norte. Se analizaron las entrevistas usando el Análisis Fenomenológico Interpretativo (IPA). Se identificaron tres temas de nivel superior: 'El Nacimiento de una Madre,' 'Lamento y Pérdida' y 'Fantasmas en el Cuarto de la Niña.' El primer tema captó el significativo cambio de identidad que las mujeres experimentan durante su transición a la maternidad. El cambio de identidad arrojó una nueva luz en sus propias experiencias de ser criadas por una madre. El segundo tema captó la lamentación y la pérdida que estas mujeres sentían debido a su relación con sus madres. La falta de significativas relaciones maternas ha dejado un vacío imposible de llenar. El tema final tuvo que ver que el elemento intergeneracional de la experiencia de estas madres y su deseo de romper un ciclo de privación materna. El rico contenido de las entrevistas enfatiza la necesidad de servicios para estar conscientes de esta lucha sobre la maternidad.
Les grands-mères maternelles jouent un rôle vital dans la transition à la maternité de leurs propres filles. Cette étude s'ajoute aux recherches précédentes en enquêtant sur l'expérience vécue de la maternité pour les femmes n'ayant pas eu une relation importante avec leurs mères. Dix mères d'enfant de moins de deux ans ont participé à un entretien semi structuré afin d'explorer leurs expériences vécues du fait d'être maman. Ces femmes ont été recrutées dans deux services parent-bébé en Irlande du Nord. Ces entretiens ont été analysés en utilisant l'Analyse Interprétive Phénoménologique (en anglais Interpretive Phenomenological Analysis, soit IPA). Trois thèmes supérieurs ont été identifiés: 'La Naissance d'une Mère', "Deuil et Perte' et 'Fantômes dans la Chambre d'enfant'. Le premier thème a capture le changement d'identité important que les femmes ont vécu durant leurs transitions à la maternité. Ce changement d'identité a apporté un éclairage nouveau sur leur propre expérience d'avoir été maternées. Le second thème a capturé le deuil et la perte que ces femmes ont ressentis du fait de leur lien à leur mère. Leur manque de relations maternelles importantes a laissé un trou impossible à remplir. Le dernier thème fait référence à l'élément intergénérationnel de l'expérience de ces mères et leur désir de casser un cycle de privation maternelle. Ce contenu riche émanant des entretiens met en lumière la prise de connaissance nécessaire de ces difficultés de la maternité dont doivent faire preuve les services.

The Bovine Genome Database (BGD) (http://bovinegenome.org) has been the key community bovine genomics database for more than a decade. To accommodate the increasing amount and complexity of bovine genomics data, BGD continues to advance its practices in data acquisition, curation, integration and efficient data retrieval. BGD provides tools for genome browsing (JBrowse), genome annotation (Apollo), data mining (BovineMine) and sequence database searching (BLAST). To augment the BGD genome annotation capabilities, we have developed a new Apollo plug-in, called the Locus-Specific Alternate Assembly (LSAA) tool, which enables users to identify and report potential genome assembly errors and structural variants. BGD now hosts both the newest bovine reference genome assembly, ARS-UCD1.2, as well as the previous reference genome, UMD3.1.1, with cross-genome navigation and queries supported in JBrowse and BovineMine, respectively. Other notable enhancements to BovineMine include the incorporation of genomes and gene annotation datasets for non-bovine ruminant species (goat and sheep), support for multiple assemblies per organism in the Regions Search tool, integration of additional ontologies and development of many new template queries. To better serve the research community, we continue to focus on improving existing tools, developing new tools, adding new datasets and encouraging researchers to use these resources.

INTRODUCTION: Faculty development (FD) supports health professions educators to develop knowledge, skills, and expertise. Whilst formal FD is a focus in the health professions education (HPE) literature, little is known about how FD occurs informally. We sought to identify opportunities and constraints for informal FD amongst health professions educators in the academic (university) setting and understand how they engage with these opportunities. METHODS: This exploratory study was conducted in one Australian university. Interviews and focus groups were conducted with undergraduate and postgraduate teachers and assessors (teachers) (n = 10); teaching team and program leaders (mid-level leaders) (n = 8); and senior (university-level) leaders (n = 2). We analysed data thematically and applied situated cognition theory. RESULTS: We identified three everyday educational practices that provide opportunities for informal FD in the academic setting: (1) applying evidence to; (2) evaluating; and (3) sharing, educational practice. Engaging with these opportunities was shaped by individuals' motivation and proactivity to engage in professional learning (effectivities) and organisational culture and structures (constraints). CONCLUSION: Applying evidence to, evaluating, and sharing educational practice provide valuable contexts for ongoing learning in the academic setting. Assisting educators and organisations to recognise and leverage these 'in situ' FD opportunities is vital in fostering a continuous learning culture.

Irrelevant emotional stimuli often capture attention, disrupting ongoing cognitive processes. In two experiments, we examined whether availability of rewards (monetary and non-monetary) can prevent this attentional capture. Participants completed a central letter identification task while attempting to ignore negative, positive, and neutral distractor images that appeared above or below the targets on 25% of trials. Distraction was indexed by slowing on distractor-present trials. Half the participants completed the task with no performance-contingent reward, while the other half earned points for fast and accurate performance. In Experiment 1, points translated into monetary reward, but in Experiment 2, points had no monetary value. In both experiments, reward reduced capture by emotional distractors, showing that even non-monetary reward can aid attentional control. These findings suggest that motivation encourages use of effective cognitive control mechanisms that effectively prevent attentional capture, even when distractors are emotional.

CONTEXT: The safe and effective application of psychomotor skills in the clinical environment is a central pillar of the health professions. The current global coronavirus pandemic has significantly impacted health professions education (HPE) and has been of particular consequence for routine face-to-face (F2F) skill education for health professionals and clinical students worldwide. What is being experienced on an unprecedented scale parallels a problem familiar to regional, rural and remote health professionals and students: the learners are willing, and the educational expertise exists, but the two are separated by the tyranny of distance. This article considers how the problem of physical distance might be overcome, so that quality skill education might continue. ISSUES: Psychomotor skills are undeniably easier to teach and learn F2F, and training schedules in tertiary, in-service and accredited professional courses reflect this. This aspect of HPE is therefore at significant risk in the context of social distancing and physical isolation. Psychomotor skills are much more complex than the physical motor outputs alone might suggest, and an F2F skill session is only one way to build the complementary aspects of new skill performance. This article argues that educators and course designers can progress with psychomotor skill education from a physical distance. LESSONS LEARNED: Videos can be used to either passively present content to learners or actively engage them. It is the design of the educational activity, rather than the resource medium itself, that enables active engagement. Furthermore, while many training schedules have been adapted to accommodate intensive F2F skill training once it is safe to do so, distributed practice and the need for reflection during the acquisition and development of new skills may challenge the pedagogical effectiveness of this approach. Skill development can be fostered in the absence of F2F teaching, and in the absence of a shared physical space. Embracing the creative licence to do so will improve equitable access to regional, rural and remote clinicians and students well beyond the resolution of the current pandemic.

Professional and tertiary health professions education (HPE) has been markedly challenged by the current novel coronavirus (COVID-19). Mandates for training organisations to reduce social contact during the global pandemic, and make learning available online, provide an opportunity for regional, rural and remote clinicians and students to more easily access learning and professional development opportunities. Online lectures, while posing an opportunity for regional, rural and remote HPE, entail potential risks. Educators who are familiar with face-to-face pedagogies may find a transition to remote, digital interaction unfamiliar, disarming, and therefore they may not design maximally engaging lectures. The strategies used in a face-to-face lecture cannot be directly transferred into the online environment. This article proposes strategies to ensure the ongoing effectiveness, efficiency and engagement of lectures transitioning from face-to-face to online delivery. Cognitive learning theory, strategies to promote learner engagement and minimise distraction, and examples of software affordances to support active learning during the lecture are proposed. This enables lecturers to navigate the challenges of lecturing in an online environment and plan fruitful online lectures during this disruptive time. These suggestions will therefore enable HPE to better meet the existing and future needs of regional, rural and remote learners who may not be able to easily access face-to-face learning upon the relaxation of social distancing measures. Strategies to provide equitable HPE to learners who cannot access plentiful, fast internet are also discussed.

Health professions education in tertiary, industrial and other contexts often entails face-to-face small group learning through tutorials. The current novel coronavirus, COVID-19, has reduced face-to-face contact, and this has challenged how health professionals and clinical students can access training, accreditation and development. Online and other remote mechanisms are available to tutors and course designers; however, they might not feel comfortable with such affordances, in light of expectations to so rapidly change familiar teaching and delivery styles. This may result in the loss of interaction and disruption of peer learning, which are hallmarks of the small group tutorial. Collaborative learning is essential to develop and refine an emerging sense of belonging to a professional community through formal studies, and interactive learning is a requirement for some registered health professions to satisfy ongoing professional accreditation. Online media has been used to promote social learning in regional, rural and remote communities for some time. Strategies for learning activity design and tutor training are proposed to equip course designers and educators to support health professions education remotely, through the synchronous, online small group. This may herald a new era of increased access to training and professional development for non-urban learners, beyond COVID-19.

The current novel coronavirus, COVID-19, has effected a significant change in the way industry-based and tertiary health professions education (HPE) can occur. Advice for strict, widespread social distancing has catalysed the transformation of course delivery into fully online design across nations. This is problematic for HPE, which has traditionally relied on face-to-face learner interaction, in the form of skills laboratories, simulation training and industry-based clinical placements. The transition to online-only course delivery has brought with it a need to address particular issues regarding the construction and delivery of quality curricula and education activities. It is in this context that regional, rural and remote health professionals and academics can provide invaluable insights into the use of technology to overcome the tyranny of distance, promote high-quality online HPE and enable the ongoing development of communities of practice. This article is the first in a series addressing the risks and opportunities in the current transition to online HPE, providing practical solutions for educators who are now unable to embrace more traditional face-to-face HPE delivery methods and activities.

Attention is biased toward emotional stimuli, even when they are irrelevant to current goals. Motivation, elicited by performance-contingent reward, reduces behavioural emotional distraction. In emotionally neutral contexts, reward is thought to encourage use of a proactive cognitive control strategy, altering anticipatory attentional settings to more effectively suppress distractors. The current preregistered study investigates whether a similar proactive shift occurs even when distractors are highly arousing emotional images. We monitored pupil area, an online measure of both cognitive and emotional processing, to examine how reward influences the time course of control. Participants (n = 110) identified a target letter flanking an irrelevant central image. Images were meaningless scrambles on 75% of trials; on the remaining 25%, they were intact positive (erotic), negative (mutilation), or neutral images. Half the participants received financial rewards for fast and accurate performance, while the other half received no performance-contingent reward. Emotional distraction was greater than neutral distraction, and both were attenuated by reward. Consistent with behavioural findings, pupil dilation was greater following emotional than neutral distractors, and dilation to intact distractors (regardless of valence) was decreased by reward. Although reward did not enhance tonic pupil dilation (an index of sustained proactive control), exploratory analyses showed that reward altered the time course of control-eliciting a sharp, rapid, increase in dilation immediately preceding stimulus onset (reflecting dynamic use of anticipatory control), that extended until well after stimulus offset. These findings suggest that reward alters the time course of control by encouraging proactive preparation to rapidly disengage from emotional distractors.

Twitter is a tool for physicians to increase engagement of learners and the public, share scientific information, crowdsource new ideas, conduct, discuss and challenge emerging research, pursue professional development and continuing medical education, expand networks around specialized topics and provide moral support to colleagues. However, new users or skeptics may well be wary of its potential pitfalls. The aims of this commentary are to discuss the potential advantages of the Twitter platform for dialogue among physicians, to explore the barriers to accurate and high-quality healthcare discourse and, finally, to recommend potential safeguards physicians may employ against these threats in order to participate productively.

AIMS: Non-fluoroscopic imaging (NFI) devices are increasingly used in ablations. The objective was to determine the utility of intracardiac echocardiography (ICE) in ablating paediatric supraventricular tachycardias (SVTs) and assess whether its integrated use with electroanatomic mapping (EAM) resulted in lower radiation exposure than use of EAM alone. METHODS AND RESULTS: Prospective, controlled, single-centre study of patients (pts) age ≥10 years, weight ≥35 kg, with SVT and normal cardiac anatomy. Patients were randomized to ICE + EAM (ICE) or EAM only (no ICE). Both had access to fluoroscopy as needed. Eighty-four pts were enroled (42 ICE, 42 no ICE). Median age was 15 years (range 10.4-23.7 years); 57% had accessory pathways, 42% atrioventricular nodal reentry tachycardia. There was no difference in radiation dose (9 mGy ICE vs. 23 mGy no ICE, P = 0.37) or fluoroscopy time (1.1 min ICE vs. 1.5 min no ICE, P = 0.38). Transseptal punctures were performed in 25 pts (16 ICE, 9 no ICE), with ICE reducing radiation (8 mGy ICE vs. 62 mGy no ICE, P = 0.002) and fluoroscopy time (1.1 min ICE vs. 4.5 min no ICE, P = 0.01). Zero fluoroscopy was achieved in 13 pts (15% of total, 5 ICE, 8 no ICE), and low-dose cases (<50 mGy) in 57 pts (68% of total, 33 ICE, 24 no ICE). Acute success was 95% for ICE, 88% for no ICE. CONCLUSION: Use of an integrated EAM/ICE system was no better than EAM alone in limiting radiation, but can be helpful for transseptal punctures. Given the low dose savings, use of ICE may be weighed against its financial cost. Low-fluoroscopy cases are performed in most NFI procedures.

This article describes a new database (named "EMAP") of 145 individuals' reactions to emotion-provoking film clips. It includes electroencephalographic and peripheral physiological data as well as moment-by-moment ratings for emotional arousal in addition to overall and categorical ratings. The resulting variation in continuous ratings reflects inter-individual variability in emotional responding. To make use of the moment-by-moment data for ratings as well as neurophysiological activity, we used a machine learning approach. The results show that algorithms that are based on temporal information improve predictions compared to algorithms without a temporal component, both within and across participant modeling. Although predicting moment-by-moment changes in emotional experiences by analyzing neurophysiological activity was more difficult than using aggregated experience ratings, selecting a subset of predictors improved the prediction. This also showed that not only single features, for example, skin conductance, but a range of neurophysiological parameters explain variation in subjective fluctuations of subjective experience.

Unavoidable stress can lead to perceived lack of control and learned helplessness, a risk factor for depression. Avoiding punishment and gaining rewards involve updating the values of actions based on experience. Such updating is however useful only if action values are sufficiently stable, something that a lack of control may impair. We examined whether self-reported stress uncontrollability during the first wave of the COVID-19 pandemic predicted impaired reward-learning. In a preregistered study during the first-wave of the COVID-19 pandemic, we used self-reported measures of depression, anxiety, uncontrollable stress, and COVID-19 risk from 427 online participants to predict performance in a three-armed-bandit probabilistic reward learning task. As hypothesised, uncontrollable stress predicted impaired learning, and a greater proportion of probabilistic errors following negative feedback for correct choices, an effect mediated by state anxiety. A parameter from the best-fitting hidden Markov model that estimates expected beliefs that the identity of the optimal choice will shift across images, mediated effects of state anxiety on probabilistic errors and learning deficits. Our findings show that following uncontrollable stress, anxiety promotes an overly volatile representation of the reward-structure of uncertain environments, impairing reward attainment, which is a potential path to anhedonia in depression.

OBJECTIVES: To engage children who have experienced cancer, childhood cancer survivors, their families and professionals to systematically identify and prioritise research questions about childhood cancer to inform the future research agenda. DESIGN: James Lind Alliance Priority Setting Partnership. SETTING: UK health service and community. METHODS: A steering group oversaw the initiative. Potential research questions were collected in an online survey, then checked to ensure they were unanswered. Shortlisting via a second online survey identified the highest priority questions. A parallel process with children was undertaken. A final consensus workshop was held to determine the Top 10 priorities. PARTICIPANTS: Children and survivors of childhood cancer, diagnosed before age 16, their families, friends and professionals who work with this population. RESULTS: Four hundred and eighty-eight people submitted 1299 potential questions. These were refined into 108 unique questions; 4 were already answered and 3 were under active study, therefore, removed. Three hundred and twenty-seven respondents completed the shortlisting survey. Seventy-one children submitted questions in the children's surveys, eight children attended a workshop to prioritise these questions. The Top 5 questions from children were taken to the final workshop where 23 questions in total were discussed by 25 participants (young adults, carers and professionals). The top priority was 'can we find effective and kinder (less burdensome, more tolerable, with fewer short and long-term effects) treatments for children with cancer, including relapsed cancer?' CONCLUSIONS: We have identified research priorities for children's cancer from the perspectives of children, survivors, their families and the professionals who care for them. Questions reflect the breadth of the cancer experience, including diagnosis, relapse, hospital experience, support during/after treatment and the long-term impact of cancer. These should inform funding of future research as they are the questions that matter most to the people who could benefit from research.

Epidemiological evidence indicates that supplementation with some dietary factors is associated with a lower incidence of cancer. An effective cancer prevention strategy for the millions of people worldwide who have been exposed to asbestos could have enormous benefit. We tested whether dietary supplementation of the antioxidants vitamin A, E, and selenium could alter the pattern of disease in the MexTAg transgenic mouse model, in which mice uniformly develop mesothelioma after asbestos exposure. We focused on antioxidants because one of the most widely accepted hypotheses for the mechanism by which asbestos fibers cause cancer proposes the involvement of reactive oxygen and nitrogen species. We compared the survival of MexTAg mice that had been inoculated with asbestos fed on diets supplemented with 250,000 IU/kg vitamin A (retinoic acid), or 1,000 mg/kg vitamin E (α-tocopherol acetate) or 3 mg/kg selenium, or both vitamin E and selenium concurrently and, additionally, diets deficient in each antioxidant. We found that neither the time to develop symptoms of disease nor overall survival times were altered by any of the diets. We conclude that the data do not support the notion that dietary antioxidants will moderate the rate of mesothelioma in asbestos-exposed populations.

Vulnerability to depression and non-response to Selective Serotonin Reuptake Inhibitors (SSRIs) are associated with specific neurophysiological characteristics including greater right hemisphere (RH) relative to left hemisphere (LH) activity. The present study investigated the relationship between hemispheric specialization and processing of emotional words using a divided visual field paradigm administered to never-depressed and previously-depressed individuals, who were subdivided into SSRI responders and non-responders. SSRI responders and never-depressed participants were similar in their left hemispheric lateralization for evaluating emotional words. In contrast, SSRI non-responders showed a relative shift towards RH processing of negative words, and a strong bias toward negative evaluation of words presented to the RH. The results are discussed within the context of a biological-cognitive model of vulnerability to depression.

MaizeMine is the data mining resource of the Maize Genetics and Genome Database (MaizeGDB; http://maizemine.maizegdb.org). It enables researchers to create and export customized annotation datasets that can be merged with their own research data for use in downstream analyses. MaizeMine uses the InterMine data warehousing system to integrate genomic sequences and gene annotations from the Zea mays B73 RefGen_v3 and B73 RefGen_v4 genome assemblies, Gene Ontology annotations, single nucleotide polymorphisms, protein annotations, homologs, pathways, and precomputed gene expression levels based on RNA-seq data from the Z. mays B73 Gene Expression Atlas. MaizeMine also provides database cross references between genes of alternative gene sets from Gramene and NCBI RefSeq. MaizeMine includes several search tools, including a keyword search, built-in template queries with intuitive search menus, and a QueryBuilder tool for creating custom queries. The Genomic Regions search tool executes queries based on lists of genome coordinates, and supports both the B73 RefGen_v3 and B73 RefGen_v4 assemblies. The List tool allows you to upload identifiers to create custom lists, perform set operations such as unions and intersections, and execute template queries with lists. When used with gene identifiers, the List tool automatically provides gene set enrichment for Gene Ontology (GO) and pathways, with a choice of statistical parameters and background gene sets. With the ability to save query outputs as lists that can be input to new queries, MaizeMine provides limitless possibilities for data integration and meta-analysis.
