Factors Associated with Shock at Presentation in Kawasaki Disease Versus Multisystem Inflammatory Syndrome in Children Associated with COVID-19.

Background: While clinical overlap between Kawasaki disease (KD) and multisystem inflammatory syndrome in children (MIS-C) has been evident, information regarding those presenting with shock has been limited. We sought to determine associations with shock within and between diagnosis groups.

Methods: The International KD Registry enrolled contemporaneous patients with either KD or MIS-C from 39 sites in 7 countries from 01/2020 to 01/2023.

Intrapatient Intermetastatic Heterogeneity Determined by Triple-Tracer PET Imaging in mCRPC Patients and Correlation to Survival: The 3TMPO Cohort Study.

Intrapatient intermetastatic heterogeneity (IIH) has been demonstrated in metastatic castration-resistant prostate cancer (mCRPC) patients and is of the utmost importance for radiopharmaceutical therapy (RPT) eligibility. This study was designed to determine the prevalence of IIH and RPT eligibility in mCRPC patients through a triple-tracer PET imaging strategy. This was a multisite prospective observational study in which mCRPC patients underwent both F-FDG and Ga-prostate-specific membrane antigen (PSMA)-617 PET/CT scans.

Meta-Analysis of Risk Factors for Congenital Heart Disease: Part 2, Maternal Medication, Reproductive Technologies, and Familial and Fetal Factors.

Background: The quantitative effects of congenital heart disease (CHD) risk factors are not fully understood. We conducted a meta-analysis of all CHD risk factors. This report explores maternal medication, assisted reproductive technologies (ART), and familial and fetal factors.

Systematic Review and Meta-analysis of Prenatal Risk Factors for Congenital Heart Disease: Part 1, Maternal Chronic Diseases and Parental Exposures.

Background: There is considerable heterogeneity in studies on prenatal risk factors for congenital heart diseases (CHDs). We performed a meta-analysis of all nongenetic factors of CHDs. This report presents results of factors related to maternal chronic diseases and parental exposures.

Liberal or Restrictive Transfusion Strategy in Patients with Traumatic Brain Injury.

Background: The effect of a liberal transfusion strategy as compared with a restrictive strategy on outcomes in critically ill patients with traumatic brain injury is unclear.

Methods: We randomly assigned adults with moderate or severe traumatic brain injury and anemia to receive transfusion of red cells according to a liberal strategy (transfusions initiated at a hemoglobin level of ≤10 g per deciliter) or a restrictive strategy (transfusions initiated at ≤7 g per deciliter). The primary outcome was an unfavorable outcome as assessed by the score on the Glasgow Outcome Scale-Extended at 6 months, which we categorized with the use of a sliding dichotomy that was based on the prognosis of each patient at baseline.

A trainee's perspective on scientific conferences.

Attending and presenting at conferences is a preeminent experience during scientific training. This article provides a trainee's perspective on strategies to promote trainee growth before, during and after scientific meetings, taking the initiatives implemented by the Canadian Society for Immunology (CSI) as an example. A foremost action was the establishment of the Trainee Engagement Committee (TEC) in 2020.

Obesity and Outcomes of Kawasaki Disease and COVID-19-Related Multisystem Inflammatory Syndrome in Children.

Importance: Obesity may affect the clinical course of Kawasaki disease (KD) in children and multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19.

Objective: To compare the prevalence of obesity and associations with clinical outcomes in patients with KD or MIS-C.

Design, Setting, And Participants: In this cohort study, analysis of International Kawasaki Disease Registry (IKDR) data on contemporaneous patients was conducted between January 1, 2020, and July 31, 2022 (42 sites, 8 countries).

Kawasaki Disease in the Time of COVID-19 and MIS-C: The International Kawasaki Disease Registry.

Background: Patients with multisystem inflammatory syndrome in children (MIS-C) and Kawasaki disease (KD) have overlapping clinical features. We compared demographics, clinical presentation, management, and outcomes of patients according to evidence of previous SARS-CoV-2 infection.

Methods: The International Kawasaki Disease Registry (IKDR) enrolled KD and MIS-C patients from sites in North, Central, and South America, Europe, Asia, and the Middle East.

Adapting the Healthy Work Environment Assessment Tool for French-Canadian Intensive Care Nurses.

Background: Self-administered instruments are used to measure components of work environments that cannot be measured directly. The Healthy Work Environment Assessment Tool (HWEAT) of the American Association of Critical-Care Nurses is a promising instrument. However, it is available only in English and Japanese, precluding its use in other populations and cross-national comparisons.

Thermogenic responses to different clamped skin temperatures in cold-exposed men and women.

Despite many decades of research examining thermoregulatory responses under varying cold stresses in humans, very little is known about the variability in metabolic heat production and shivering activity. Here, we used a novel closed-loop mean skin temperature clamping technique with a liquid-conditioned suit to isolate the effects of mean skin temperature on the subjective evaluation of thermal sensation, heat production, shivering responses, and oxidative fuel selection in young, lean, and healthy men ( = 12) and women ( = 12). Our results showed a skin temperature-dependent increase in metabolic heat production (5.

Incremental Detection of Severe Congenital Heart Disease by Fetal Echocardiography Following a Normal Second Trimester Ultrasound Scan in Québec, Canada.

Background: The benefit of fetal echocardiograms (FE) to detect severe congenital heart diseases (SCHD) in the setting of a normal second-trimester ultrasound is unclear. We aimed to assess whether the increase in SCHD detection rates when FE are performed for risk factors in the setting of a normal ultrasound was clinically significant to justify the resources needed.

Methods: This is a multicenter, population-based, retrospective cohort study, including all singleton pregnancies and offspring in Quebec (Canada) between 2007 and 2015.

Occupational Adaptation of People Living With Fibromyalgia: A Systematic Review and Thematic Synthesis.

Importance: Fibromyalgia (FM) is a chronic pain disorder that interferes with daily activities. Because occupational adaptation varies among people, there is a need to determine which factors can influence adaptation to FM in order to better intervene with them.

Objective: To understand the occupational adaptation process of people living with FM.

Src family kinases inhibit differentiation of intestinal epithelial cells through the Hippo effector YAP1.

Intestinal cell lineage differentiation is a tightly regulated mechanism that involves several intracellular signaling pathways affecting the expression of a variety of transcription factors, which ultimately regulate cell specific gene expression. Absorptive and goblet cells are the two main epithelial cell types of the intestine. Previous studies from our group using an shRNA knockdown approach have shown that YAP1, one of the main Hippo pathway effectors, inhibits the differentiation of these two cell types.

The Mathematical Limitations of Fetal Echocardiography as a Screening Tool in the Setting of a Normal Second-Trimester Ultrasound.

Background: The effectiveness of screening strategies targeting pregnancies at higher risk of congenital heart disease (CHD) is reduced by the low prevalence of severe CHD, the increase in CHD detection rates by second-trimester ultrasound (U/S), and the high proportion of severe CHD in low-risk pregnancies. We aimed to determine situations in which additional screening by fetal echocardiography (FE) would result in a significant increase in sensitivity and a sizable decrease in the false-negative rate of detection of severe CHD.

Methods: We simulated the change in the numbers of detected severe CHD cases when FE is offered to women with a normal second-trimester U/S who have a higher risk of bearing a child with CHD, compared to U/S alone.

Utilization and effect of neuromuscular blockade in a randomized trial of high-frequency oscillation.

Purpose: We evaluated characteristics associated with neuromuscular blockade (NMB) use, center-level variation, and whether NMB mediated excess mortality among patients assigned to high-frequency oscillatory ventilation (HFOV) in the OSCILLATE trial.

Materials And Methods: NMB exposure was defined as receipt after randomization; the primary outcome was hospital mortality. Descriptive analyses compared NMB-exposed vs unexposed patients.

Healthy for My Baby Research Protocol- a Randomized Controlled Trial Assessing a Preconception Intervention to Improve the Lifestyle of Overweight Women and Their Partners.

Preconception lifestyle interventions appear promising to reduce pregnancy complications, prevent adult cardiometabolic diseases, and prevent childhood obesity. These interventions have almost exclusively been studied in populations of obese infertile women. The development of preconception lifestyle interventions targeting a broader population of overweight and obese women without a history infertility and their partners is needed.
