Contexte : Les facteurs de risque de complications graves de l'infection par le SRAS-CoV-2 n'ont pas ete bien etablis chez les enfants. Nous avons voulu decrire les hospitalisations pediatriques associees au SRAS-CoV-2 au Canada et identifier les facteurs de risque de maladie grave. Methodes : Nous avons procede a une etude prospective nationale en utilisant l'infrastructure du Programme canadien de surveillance pediatrique (PCSP). Les hospitalisations d'enfants ayant contracte une infection par le SRAS-CoV-2 confirmee en laboratoire de microbiologie ont ete rapportees du 8 avril au 31 decembre 2020 au moyen de questionnaires hebdomadaires en ligne distribues au reseau du PCSP, qui compte plus de 2800 pediatres. Nous avons categorise les hospitalisations comme suit : liees a la COVID-19, infections decouvertes fortuitement, ou hospitalisations pour des raisons sociales ou de controle des infections, et degage les facteurs de risque associes a la gravite de la maladie chez les patients hospitalises. Resultats : Sur les 264 hospitalisations d'enfants ayant contracte le SRAS-CoV-2 au cours de la periode de l'etude de 9 mois, 150 (56,8 %) ont ete associees a la COVID-19 et 100 (37,9 %o) etaient des cas decouverts fortuitement (admission pour d'autres raisons et decouverte fortuite du SRAS-CoV-2 par depistage positif). Les nourrissons (37,3 %) et les adolescents (29,6 %) representaient la majorite des cas. Parmi les hospitalisations liees a la COVID-19, 52 patients (34,7 %) etaient atteints d'une forme grave de la mala die, dont 42 (28,0 % des cas lies a la COVID-19) ont eu besoin d'une forme d'assistance respiratoire ou hemodynamique, et 59 (39,3 %o) presentaient au moins 1 comorbidite sous-jacente. Les enfants atteints d'obesite, de maladies neurologiques chroniques ou de maladies pulmonaires chroniques, a l'exclusion de l'asthme, etaient plus susceptibles de presenter une forme grave ou critique de la COVID-19. Interpretation : Parmi les enfants hospitalises au Canada chez lesquels on a diagnostique une infection par le SRAS-CoV-2 au debut de la pandemie de COVID-19, la decouverte fortuite du SRAS-CoV-2 a ete frequente. Chez les enfants hospitalises pour une COVID-19 aigue, l'obesite et les comorbidites neurologiques et respiratoires ont ete associees a une gravite accrue., En date du 31 decembre 2020, le Canada comptait 581 427 cas confirmes d'infection par le SRAS-CoV-2 (1). Comme dans d'autres pays, la plupart des infections confirmees ont ete diagnostiquees [...]

Background: Risk factors for severe outcomes of SARS-CoV-2 infection are not well established in children. We sought to describe pediatric hospital admissions associated with SARS-CoV-2 infection in Canada and identify risk factors for more severe disease. Methods: We conducted a national prospective study using the infrastructure of the Canadian Paediatric Surveillance Program (CPSP). Cases involving children who were admitted to hospital with microbiologically confirmed SARS-CoV-2 infection were reported from Apr. 8 to Dec. 31 2020, through weekly online questionnaires distributed to the CPSP network of more than 2800 pediatricians. We categorized hospital admissions as related to COVID-19, incidental, or for social or infection control reasons and determined risk factors for disease severity in hospital. Results: Among 264 hospital admissions involving children with SARS-CoV-2 infection during the 9-month study period, 150 (56.8%) admissions were related to COVID-19 and 100 (37.9%) were incidental infections (admissions for other reasons and found to be positive for SARS-CoV-2 on screening). Infants (37.3%) and adolescents (29.6%) represented most cases. Among hospital admissions related to COVID-19, 52 (34.7%) had critical disease, 42 (28.0%) of whom required any form of respiratory or hemodynamic support, and 59 (39.3%) had at least 1 underlying comorbidity. Children with obesity, chronic neurologic conditions or chronic lung disease other than asthma were more likely to have severe or critical COVID-19. Interpretation: Among children who were admitted to hospital with SARS-CoV-2 infection in Canada during the early COVID-19 pandemic period, incidental SARS-CoV-2 infection was common. In children admitted with acute COVID-19, obesity and neurologic and respiratory comorbidities were associated with more severe disease., As of Dec. 31, 2020, Canada had 581427 confirmed cases of SARS-CoV-2 infection. (1) Similar to other countries, most confirmed infections were in adults, in part because of initial testing [...]

AbstractInoculation theory, which applies the biological concept of vaccination to misinformation, provides a range of ways to effectively build resilience against misinformation. In this article, we define and organize the various types of inoculation, which includes three delivery mechanisms that can be useful in the classroom—passive, active, and experiential. In passive inoculations, students passively receive inoculating messages, whereas in active inoculations, students actively generate misinformation using misleading techniques. We introduce a new category of inoculation—experiential—which involves misleading students and then debriefing them on how they were misled. We then describe how these three techniques were implemented in a general education science class designed to teach critical thinking and science literacy. Through these activities, we illustrate how the different types of inoculation can be creatively combined to maximize student engagement and learning.

Many poor women who are diagnosed and treated for a molar pregnancy may not comply with follow-up appointments, according to a study of 121 women in Dallas, Texas. Only half of the Hispanic women and 11% of the black women went to all of the follow-up appointments after they were diagnosed and treated. Molar pregnancy is an abnormal growth from the placenta during pregnancy that can become cancerous.

Monoamine and amino acid content were measured in brain regions from 12 week old male, homozygous Brattleboro (DI,n=12) and Long-Evans control (LE,n=12) rats. Norepinephrine (NE) content was significantly elevated (16–25%) in the spinal cord, pons-medulla and anterior hypothalamus of DI rats when compared to LE controls. NE content of the neurointermediate lobe of pituitary in DI rats was almost twice that of LE controls. Serotonin content was also significantly elevated in the spinal cord, pons-medulla, anterior hypothalamus and forebrain of DI rats relative to the LE controls. Taurine content in DI rats was increased (31–42%) above that of LE rats in the anterior hypothalamus, striatum and forebrain. Glutamine content was also greater in DI rats than LE in the spinal cord, pons-medulla, anterior hypothalamus, striatum, hippocampus and forebrain. The changes in monoamine and amino acid content were discussed in relation to the cardiovascular and osmoregulatory deficits that are present in DI rats due to arginine vasopressin (AVP) deficiency. The possible role of AVP in modulating NE turnover was also discussed. The increase in brain TAU content in DI rats may be a physiological response to hypernatremia.

Background: Abdominal compartment syndrome is a rare condition in which increased intra-abdominal pressure adversely affects perfusion and viability of the viscera, and the cardiovascular, respiratory, and renal systems. The syndrome follows acute abdominal events such as abdominal trauma, intraperitoneal hemorrhage, or intra-abdominal infection.
