Current state of neurodevelopmental and psychosocial care practices for paediatric patients with ventricular assist devices: an Advanced Cardiac Therapies Improving Outcomes Network and Cardiac Neurodevelopmental Outcome Collaborative collaborative survey.

Purpose: Paediatric patients with heart failure requiring ventricular assist devices are at heightened risk of neurologic injury and psychosocial adjustment challenges, resulting in a need for neurodevelopmental and psychosocial support following device placement. Through a descriptive survey developed in collaboration by the Advanced Cardiac Therapies Improving Outcomes Network and the Cardiac Neurodevelopmental Outcome Collaborative, the present study aimed to characterise current neurodevelopmental and psychosocial care practices for paediatric patients with ventricular assist devices.

Method: Members of both learning networks developed a 25-item electronic survey assessing neurodevelopmental and psychosocial care practices specific to paediatric ventricular assist device patients.

Reducing donor acceptance practice variation - Learnings from a discussion forum.

Purpose: Although waitlist mortality is unacceptably high, nearly half of donor heart offers are rejected by pediatric heart transplant centers. The Advanced Cardiac Therapy Improving Outcome Network (ACTION) and Pediatric Heart Transplant Society (PHTS) convened a multi-institutional donor decision discussion forum (DDDF) aimed at assessing donor acceptance practices and reducing practice variation.

Methods: A 1-h-long virtual DDDF for providers across North America, the United Kingdom, and Brazil was held monthly.

Considerations for Advanced Heart Failure Consultation in Individuals With Fontan Circulation: Recommendations From ACTION.

Individuals with Fontan circulation are at risk of late mortality from both cardiac and noncardiac causes. Despite the known risk of mortality, referral indications for advanced heart failure care vary between centers, and many individuals die from Fontan circulation-related complications either after late consideration for advanced heart failure therapies or having never seen a heart failure specialist. There is a critical need for guidelines to direct appropriately timed referral for advanced heart failure consultation.

Patient and parent-reported outcomes in paediatric ventricular assist device support: a multi-center ACTION learning network feasibility and pilot experience.

Background: Patient- and proxy-reported outcomes (PROs) are an important indicator of healthcare quality and can be used to inform treatment. Despite the widescale use of PROs in adult cardiology, they are underutilised in paediatric cardiac care. This study describes a six-center feasibility and pilot experience implementing PROs in the paediatric and young adult ventricular assist device population.

Heroism and paramedic practice: A constructivist metasynthesis of qualitative research.

Objectives: We aimed to identify, appraise, and synthesise the qualitative literature to develop theory on heroism and paramedic practice.

Hypothesis/research Question: What does published literature tell us about heroism and paramedic practice?

Setting: Paramedics and other healthcare workers (HCWs) faced an outpouring of public support for them early in the COVID-19 pandemic which brought into focus the relationship between them and society, where they are portrayed as heroes.

Participants: We conducted a metasynthesis using Evolved Grounded Theory and procedural guidelines of Noblit and Hare to guide analysis.

Protocol for a constructivist metasynthesis of qualitative research of heroism and paramedic practice.

Background: Exceptional demands have been placed on paramedics and other healthcare workers (HCWs) during the COVID-19 pandemic. An overwhelming outpouring of public support has unfolded, bringing into focus the relationship between paramedics, other HCWs and society, where they are portrayed as heroes. Scholars have studied the notion of heroism to society, and characteristics of such heroic status include: the voluntary nature of a heroic act, risk of physical or social harm, willingness to accept the consequences of action, acting for the benefit of others and without the expectation of gain.

The Creation of a Pediatric Health Care Learning Network: The ACTION Quality Improvement Collaborative.

Improving the outcomes of pediatric patients with congenital heart disease with end-stage heart failure depends on the collaboration of all stakeholders; this includes providers, patients and families, and industry representatives. Because of the rarity of this condition and the heterogeneity of heart failure etiologies that occur at pediatric centers, learnings must be shared between institutions and all disciplines to move the field forward. To foster collaboration, excel discovery, and bring data to the bedside, a new, collaborative quality improvement science network-ACTION (Advanced Cardiac Therapies Improving Outcomes Network)-was developed to meet the needs of the field.

Collaboration and new data in ACTION: a learning health care system to improve pediatric heart failure and ventricular assist device outcomes.

Outcomes in pediatric heart failure and ventricular assist devices (VADs) remain suboptimal. Given the complexity and limited numbers, centers cannot be expected to acquire mastery and generalizable knowledge independently. Recognizing this problem, the community has formed Advanced Cardiac Therapies Improving Outcomes Network (ACTION), a collaborative learning health care system committed to unrelenting collaboration and continuous learning to improve critical outcomes in pediatric heart failure.

Activating Mutations in and in Canine Histiocytic Sarcomas.

While the genetic contributions to the predisposition of Bernese mountain dogs (BMDs) to histiocytic sarcoma (HS) remains unclear, some insights into key genetic drivers have been gained. Our group recently reported a mutation in the gene (E76K). We have now identified a second missense mutation in PTPN11 (G503V), and a mutation in KRAS (Q61H) present in HS cell lines.

Development of an Orthotopic Intrasplenic Xenograft Mouse Model of Canine Histiocytic Sarcoma and Its Use in Evaluating the Efficacy of Treatment with Dasatinib.

Canine histiocytic sarcoma is a highly aggressive and metastatic hematopoietic neoplasm that responds poorly to currently available treatment regimens. Our goal was to establish a clinically relevant xenograft mouse model to assess the preclinical efficacy of novel cancer treatment protocols for histiocytic sarcoma. We developed an intrasplenic xenograft mouse model characterized by consistent tumor growth and development of metastasis to the liver and other abdominal organs.
