Mostly worse, occasionally better: impact of COVID-19 pandemic on the mental health of Canadian children and adolescents

This large cross-sectional study examined the impact of COVID-19 emergency measures on child/adolescent mental health for children/adolescents with and without pre-existing psychiatric diagnoses. Using adapted measures from the CRISIS questionnaire, parents of children aged 6–18 (N = 1013; 56% male; 62% pre-existing psychiatric diagnosis) and self-reporting children/adolescents aged 10–18 (N = 385) indicated changes in mental health across six domains: depression, anxiety, irritability, attention, hyperactivity, and obsessions/compulsions. Changes in anxiety, irritability, and hyperactivity were calculated for children aged 2–5 years using the Strengths and Difficulties Questionnaire. COVID-19 exposure, compliance with emergency measures, COVID-19 economic concerns, and stress from social isolation were measured with the CRISIS questionnaire. Prevalence of change in mental health status was estimated for each domain; multinomial logistic regression was used to determine variables associated with mental health status change in each domain. Depending on the age group, 67–70% of children/adolescents experienced deterioration in at least one mental health domain; however, 19–31% of children/adolescents experienced improvement in at least one domain. Children/adolescents without and with psychiatric diagnoses tended to experience deterioration during the first wave of COVID-19. Rates of deterioration were higher in those with a pre-exiting diagnosis. The rate of deterioration was variable across different age groups and pre-existing psychiatric diagnostic groups: depression 37–56%, anxiety 31–50%, irritability 40–66%, attention 40–56%, hyperactivity 23–56%, obsessions/compulsions 13–30%. Greater stress from social isolation was associated with deterioration in all mental health domains (all ORs 11.12–55.24). The impact of pre-existing psychiatric diagnosis was heterogenous, associated with deterioration in depression, irritability, hyperactivity, obsession/compulsions for some children (ORs 1.96–2.23) but also with improvement in depression, anxiety, and irritability for other children (ORs 2.13–3.12). Economic concerns were associated with improvement in anxiety, attention, and obsessions/compulsions (ORs 3.97–5.57). Children/adolescents with and without pre-existing psychiatric diagnoses reported deterioration. Deterioration was associated with increased stress from social isolation. Enhancing social interactions for children/adolescents will be an important mitigation strategy for current and future COVID-19 waves

Abstract Researchers and practitioners devote substantial effort to targeting banner advertisements, but less effort on how to communicate with consumers once targeted. Morphing enables a website to learn (actively and near optimally) which banner advertisements to serve to each cognitive-style segment in order to maximize click-through, brand consideration, and purchase. Cognitive-style segments are identified automatically from consumers' clickstreams. This paper describes the first large-sample random-assignment field-test of banner morphing -over 100,000 consumers viewing over 450,000 banners on CNET.com. On relevant webpages, CNET's click-through rates almost doubled relative to control banners. We supplement the CNET field test with a focused experiment on an automotive information-andrecommendation website. The focused experiment replaces automated learning with a longitudinal design to test the premise of morph-to-segment matching. Banners matched to cognitive styles, as well as the stage of the consumer's buying process and body-type preference, significantly increase click-through rates, brand consideration, and purchase likelihood relative to a control. Together the field and the focused experiments demonstrate that matching cognitive styles provide significant benefits above and beyond more-traditional targeting. Such improved banner effectiveness has strategic implications for allocations among media

Abstract Morphing enables a website to learn (actively and near optimally) which banner advertisements to serve to each cognitive-style segment in order to maximize outcome measures such as click-through, brand consideration, or purchase. Consumer segments are identified automatically from consumers' clickstream choices. Morphing works best on high-traffic websites with tens of thousands of visitors because large samples are necessary to reach steady state optimally. This paper describes the first large-sample random-assignment field test of banner morphing -over 100,000 consumers viewing over 450,000 banners on CNET.com. (Previously published morphing evaluations evaluated morphing website characteristics and were based on predictive simulations using only priming-study data.) On relevant webpages, CNET's clickthrough rates almost double relative to control banners. We supplement the CNET field test with a focused experiment on an automotive information-and-recommendation website. The focused experiment replaces automated learning with a longitudinal design which tests the premise of morph-to-segment matching. Banners matched to cognitive styles, as well as the stage of the consumer's buying process and body-type preference, significantly increase click-through rates, brand consideration, and purchase likelihood relative to a control

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Web-based amateur critical reviews in comparison to traditional television counterparts

This file was last viewed in Microsoft Edge PDF viewer.Since 1907 film criticism has been a part of the mass media. In the 1970s film criticism made a leap from the pages of the local newspaper to television programming in the form of Sneak Previews hosted by Gene Siskel and Roger Ebert. Reaching a peak in ratings by 1992, the show was regularly being viewed by millions. In recent years as programming has moved from the television to the internet as a result of the digital revolution, a new breed of reporters have attempted to fill the shoes that critics like Siskel & Ebert left behind. This study analyzed one specific web based film criticism program, Half in the Bag, and compared the content recently presented by that program to 1992 episodes of Siskel and Ebert. Data was gathered in from both sources for the total length spent reviewing the film, the focus on opinion, the use of film terminology and the overall likelihood of critics to recommend a film. The goal of the study was to ultimately determine if content provided by modern day web based film critics is truly comparable to the works completed by Gene Siskel and Roger Ebert in the early 1990s. Research indicated that while appearing like their traditional counterparts, in many ways they were not comparable. Thus, while the overall trend seems to be leading to a convergence of the internet and television, and a movement of programing from the television to the web, web based film review programs like Half in the Bag are not presenting the same content that previous television reviewers did, but rather a new form of film review that focuses on analysis and a specific niche audience

A structured light approach to imaging ancient Near Eastern cylinder seals: how efficient 3D imaging may facilitate corpuswide research

This chapter presents the work of the 12-month project Seals and Their Impressions in the Ancient NearEast (SIANE), a collaborative effort of the University of Southampton, Oxford University and theUniversity of Paris (Nanterre). Recognising the need for improved visual documentation of ancientNear Eastern cylinder seals and the potential presented by new technologies, there have been severalapproaches to 3D-imaging cylinder seals in recent years (e.g. Pitzalis et al. 2008; Reh et al. 2016;Wagensonner forthcoming). SIANE focused on the development of equipment and workflow that canquickly capture the maximum amount of meaningful data from a seal, including 3D data fromstructured light and an automated production of �digital unwrappings�. The project addressed someissues regarding the physical mounting of seals and developed a method of efficient data-capture thatallows the imaging of large numbers of cylinder seals for research and presentation purposes. Aparticular research benefit from 3D image capture of entire seal collections is the potential forexploring computer-aided image recognition, which could contribute to comparative glyptic studiesas well as helping to address the question of whether any original seals can be linked to knownancient impressions on tablets or sealings possibly separated across modern collections
