PARENTING INFLUENCING CHILD AND ADOLESCENT CU TRAITS : The Role of Parental Harshness and Parental Warmth in the Development of CallousUnemotional Traits in Children and Adolescents <18: A Systematic Review.

The present review sought to clarify and synthesise the existing research of the role parental harshness and parental warmth have on children and adolescents with callous unemotional traits by comparing research across different study designs and study samples in a systematic review. The systematic review search rendered in 16 publications which revealed that callous unemotional traits moderate the relationship between parental harshness as well as parental warmth and behaviour problems in children and adolescents. The moderation effect was directed by the level of callous unemotional trait in the child or adolescent where those with low levels exhibited the most negative effects when exposed to parental harshness. Conversely, children or adolescents with elevated levels exhibited the most positive effects when being exposed to parental warmth. Furthermore, the review revealed that both forms of parenting predict changes in callous unemotional traits over time, where parental harshness increased traits and parental warmth decreased traits. These results are further discussed in relation to the contextual theories of Lykken’s parental competence and socialisation model as well as Kochanska’s conceptual model of conscience development

Type I Interferon Autoantibodies Correlate With Cellular Immune Alterations in Severe COVID-19

BackgroundInfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can lead to severe disease with increased morbidity and mortality among certain risk groups. The presence of autoantibodies against type I interferons (aIFN-Abs) is one mechanism that contributes to severe coronavirus disease 2019 (COVID-19).MethodsThis study aimed to investigate the presence of aIFN-Abs in relation to the soluble proteome, circulating immune cell numbers, and cellular phenotypes, as well as development of adaptive immunity.ResultsaIFN-Abs were more prevalent in critical compared to severe COVID-19 but largely absent in the other viral and bacterial infections studied here. The antibody and T-cell response to SARS-CoV-2 remained largely unaffected by the presence aIFN-Abs. Similarly, the inflammatory response in COVID-19 was comparable in individuals with and without aIFN-Abs. Instead, presence of aIFN-Abs had an impact on cellular immune system composition and skewing of cellular immune pathways.ConclusionsOur data suggest that aIFN-Abs do not significantly influence development of adaptive immunity but covary with alterations in immune cell numbers

Oxygen targets and 6-month outcome after out of hospital cardiac arrest: a pre-planned sub-analysis of the targeted hypothermia versus targeted normothermia after Out-of-Hospital Cardiac Arrest (TTM2) trial

International audienceAbstract Background Optimal oxygen targets in patients resuscitated after cardiac arrest are uncertain. The primary aim of this study was to describe the values of partial pressure of oxygen values (PaO 2 ) and the episodes of hypoxemia and hyperoxemia occurring within the first 72 h of mechanical ventilation in out of hospital cardiac arrest (OHCA) patients. The secondary aim was to evaluate the association of PaO 2 with patients’ outcome. Methods Preplanned secondary analysis of the targeted hypothermia versus targeted normothermia after OHCA (TTM2) trial. Arterial blood gases values were collected from randomization every 4 h for the first 32 h, and then, every 8 h until day 3. Hypoxemia was defined as PaO 2  300 mmHg. Mortality and poor neurological outcome (defined according to modified Rankin scale) were collected at 6 months. Results 1418 patients were included in the analysis. The mean age was 64 ± 14 years, and 292 patients (20.6%) were female. 24.9% of patients had at least one episode of hypoxemia, and 7.6% of patients had at least one episode of severe hyperoxemia. Both hypoxemia and hyperoxemia were independently associated with 6-month mortality, but not with poor neurological outcome. The best cutoff point associated with 6-month mortality for hypoxemia was 69 mmHg (Risk Ratio, RR = 1.009, 95% CI 0.93–1.09), and for hyperoxemia was 195 mmHg (RR = 1.006, 95% CI 0.95–1.06). The time exposure, i.e., the area under the curve (PaO 2 -AUC), for hyperoxemia was significantly associated with mortality ( p = 0.003). Conclusions In OHCA patients, both hypoxemia and hyperoxemia are associated with 6-months mortality, with an effect mediated by the timing exposure to high values of oxygen. Precise titration of oxygen levels should be considered in this group of patients. Trial registration : clinicaltrials.gov NCT02908308 , Registered September 20, 2016
