Obesity-induced mesenteric PVAT remodelling is sexually dimorphic, but not driven by ovarian hormones : Short title: Obesity induces sex-specific responses in mesenteric PVAT.

Background: Obesity, a major risk factor for cardiovascular disease (CVD), is associated with hypertension and vascular dysfunction. Perivascular adipose tissue (PVAT), a metabolically active tissue surrounding blood vessels, plays a key role in regulating vascular tone. In obesity, PVAT becomes dysregulated which may contribute to vascular dysfunction; how sex impacts the remodelling of PVAT and thus the altered vascular contractility during obesity is unclear.

Risk of bias assessment tools often addressed items not related to risk of bias and used numerical scores.

Objective: We aimed to determine whether the existing risk of bias assessment tools addressed constructs other than risk of bias or internal validity, and whether they used numerical scores to express quality, which is discouraged and may be a misleading approach.

Methods: We searched Ovid MEDLINE and Embase to identify quality appraisal tools across all disciplines in human health research. Tools designed specifically to evaluate reporting quality were excluded.

Practice patterns for acquiring neuroimaging after pediatric in-hospital cardiac arrest.

Aims: To determine which patient and cardiac arrest factors were associated with obtaining neuroimaging after in-hospital cardiac arrest, and among those patients who had neuroimaging, factors associated with which neuroimaging modality was obtained.

Methods: Retrospective cohort study of patients who survived in-hospital cardiac arrest (IHCA) and were enrolled in the ICU-RESUS trial (NCT02837497).

Results: We tabulated ultrasound (US), CT, and MRI frequency within 7 days following IHCA and identified patient and cardiac arrest factors associated with neuroimaging modalities utilized.

The impact of pediatric post-cardiac arrest care on survival: A multicenter review from the AHA get with the Guidelines®-resuscitation post-cardiac arrest care registry.

Aim: Adherence to post-cardiac arrest care (PCAC) recommendations is associated with improved outcomes for adults. We aimed to describe the survival impact of meeting American Heart Association (AHA) PCAC guidelines in children after cardiac arrest.

Methods: We conducted a retrospective study using Get With The Guidelines® Resuscitation's (GWTG®-R) registry to describe the PCAC of patients ≤ 18 years old who suffered an in-hospital or out-of-hospital cardiac arrest (IHCA or OHCA).
