    The present study compared the teacher ratings and self-perceptions of two groups of children with emotional and/or behavioural difficulties: a) Those with attention-deficit hyperactivity disorder (ADHD) and b) those with average or below average levels of hyperactivity and attention. Results showed that the ADHD group was rated more poorly by teachers in academic, social, and behavioural domains. This group also inflated their competency ratings in these domains relative to teacher report more than the comparison group.La présente étude compare les différences entre la manière dont les enseignants perçoivent deux groupes d’enfants ayant des difficultés affectives et (ou) comportementales et celle dont les enfants se perçoivent eux-mêmes : a) Un groupe souffrant du trouble d’hyperactivité avec déficit de l’attention (TDAH) et b) Un groupe ayant des niveaux d’hyperactivité et d’attention moyens ou inférieurs à la moyenne. Les résultats ont mis en évidence que le groupe était moins bien noté par les enseignements dans les domaines scolaire, social et comportemental. En comparaison des enseignants, ce groupe a davantage surestimé ses compétences dans ces domaines que le groupe témoin

    We use contingent valuation to elicit WTP for a reduction in the risk of dying for cardiovascular and respiratory causes, the most important causes of premature mortality associated with heat wave and air pollution, among the Italian public. The purpose of this study is three-fold. First, we obtain WTP and VSL figures that can be applied when estimating the benefits of heat advisories, other policies that reduce the mortality effects of extreme heat, and environmental policies that reduce the risk of dying for cardiovascular and respiratory causes. Second, our experimental study design allows us to examine the sensitivity of WTP to the size of the risk reduction. Third, we examine whether the WTP of populations that are especially sensitive to extreme heat and air pollution - such as the elderly, those in compromised health, and those living alone and/or physically impaired - is different from that of other individuals. We find that WTP, and hence the VSL, depends on the risk reduction, respondent age (via the baseline risk), and respondent health status. WTP increases with the size of the risk reduction, but is not strictly proportional to it. All else the same, older individuals are willing to pay less for a given risk reduction than younger individuals of comparable characteristics. Poor health, however, tends to raise WTP, so that the appropriate VSL of elderly individuals in poor health may be quite large. Our results support the notion that the VSL is individuated

    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

    Robustness of VSL Values from Contingent Valuation Surveys

    This paper examines factors that may influence the estimates of the Value of a Statistical Life obtained from contingent valuation surveys that elicit the willingness to pay (WTP) for mortality risk reductions. We examine the importance of distributional assumptions, the choice of the welfare statistics of interest, the procedure for computing them, outliers, undesirable response effects, and internal validity of the WTP responses. We illustrate the importance of these factors using dichotomous-choice and open-ended WTP data from four recent contingent valuation surveys

    IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

    Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

    The development of self : issues of self-esteem and perspective taking in middle childhood

    This study investigated the relationship between perspective taking and self-esteem in two groups of children between 7 and 12 years of age. Forty-six third graders (mean age = 8.3 years) and 25 sixth graders (means age = 11.4 years) completed a perspective-taking task, a locus of control scale, and a self-perception measure assessing global self-esteem and specific areas of competence. There was little empirical support for the hypotheses associating perspective taking with global self-esteem, locus of control, or competence. Competence domains were intercorrelated and associated with global self-esteem. Locus of control was significantly related to social acceptance and athletic competence. Sixth graders demonstrated superior perspective-taking ability while third graders reported higher levels of self-esteem and more satisfaction with their physical appearance. Gender was related only to behavioural conduct; girls were more satisfied with their overall behaviour. The implications of these findings for self-other development are discussed

    Remediating behavior problems of young children : the impact of parent treatment acceptability and the efficacy of conjoint behavioral consultation and videotape therapy

    The present study was an exploratory investigation of the efficacy and acceptability of a parent-teacher mediated intervention program for young boys demonstrating externalizing behavior problems. A primary purpose of the study was to compare the efficacy of three indirect models of service delivery: a highly individualized behavioral consultation model (BC); group videotape therapy with minimal consultation (GVT); and a self-administered videotape therapy (VT) program. A second purpose was to investigate the acceptability and satisfaction with these programs as evaluated by parents. More specifically, the relationships between treatment acceptability and outcome as well as factors influencing parent treatment acceptability were examined. Thirty preschool and elementary school children, their parents, and teachers were assigned to one of three intervention conditions (BC, VT, and GVT). A total of 37 parents (29 mothers, 7 fathers, 1 grandmother) participated in the delivery of intervention services over an 8 to 10 week period. An A-B research design was used to analyze the effectiveness of consultation. Outcome variables included parent and teacher ratings of social skills and problem behaviors as well as direct observations. Results indicated that children's target behaviors improved from baseline to treatment in all three intervention conditions. Pretest and posttest parent treatment acceptability was assessed via rating scales, and at the end of the program parents also completed a satisfaction questionnaire. During the intervention phase, a brief semi-structured interview was used to assess parental perceptions of acceptability. High acceptability and satisfaction ratings were reported by parents in all three intervention conditions. There was partial support indicating a relationship between treatment effectiveness and acceptability but there was little evidence of an association between parental perceptions of problem-solving skill, parenting competence, a
