Engaging health system, service and consumer representatives in the co-design of a multi-criteria decision-making framework for commissioning overweight and obesity programs and services.

Background: Obesity is a multi-faceted problem that requires complex health system responses. While no single program or service is sufficient to meet every individual's needs, some criteria that increase the likelihood of program/service quality delivery to produce effective outcomes exist. However, although research on health commissioning is available internationally and is growing within the Australian context, no evidence exists of a multi-criteria decision-making framework to address the complexity required for effective commissioning of overweight and obesity early intervention and weight management programs or services.

Helical transition of the bridge helix of Cas12a is an allosteric regulator of R-loop formation and RuvC activation.

CRISPR-Cas12a is widely used for genome editing and biomarker detection since it can create targeted double-stranded DNA breaks and promote non-specific DNA cleavage after identifying specific DNA. To mitigate the off-target DNA cleavage of Cas12a, we previously developed a Cas12a variant (FnoCas12a ) by introducing double proline substitutions (K969P/D970P) in a conserved helix called the bridge helix (BH). In this work, we used cryogenic electron microscopy (cryoEM) to understand the molecular mechanisms of BH- mediated activation of Cas12a.

Diastolic Dysfunction and Survival in Patients with Preserved or Mildly Reduced Left Ventricular Ejection Fraction following Myocardial Infarction.

Background: Left ventricular ejection fraction (LVEF) is relatively indiscriminate for prognosis in patients with preserved or mildly reduced LVEF (>40%) following myocardial infarction (MI). This study sought to determine the value of guideline-based assessment of diastolic dysfunction (DD) in predicting long-term all-cause and cardiac mortality in patients with a first-ever MI and LVEF>40%.

Methods: A retrospective single centre study involving 2234 patients with a first-ever MI (STEMI or NSTEMI) with LVEF>40% was performed.

The role of multi-modality imaging for the assessment of left atrium and left atrial appendage. A clinical consensus statement of the European Association of Cardiovascular Imaging (EACVI), European Heart Rhythm Association (EHRA) of the European Society of Cardiology (ESC).

Structural, architectural, contractile or electrophysiological alterations may occur in the left atrium (LA). The concept of LA cardiopathy is supported by accumulating scientific evidence demonstrating that LA remodeling has become a cornerstone diagnostic and prognostic marker. The structure and the function of LA and left atrial appendage (LAA) which is an integral part of the LA, are key elements for a better understanding of multiple clinical conditions, most notably atrial fibrillation (AF), cardioembolism, heart failure and mitral valve diseases.
