Globally, nearly 64 million individuals are currently affected by heart failure, causing considerable medical, financial, and social challenges. One therapeutic option for patients with advanced heart failure is mechanical circulatory support (MCS) which is widely used for short-term or long-term management.

Palliative Care Referral Patterns and Implications for Standardization in Cardiac ICU.

Evidence suggests that pediatric palliative care involvement (PPC) is beneficial to medically complex patients. Historically, PPC involvement has been overlooked or delayed and varies by institution but PPC awareness has increased in cardiovascular ICUs (CVICU) and so we investigated frequency and timeliness of PPC referral for patients dying in ICU. Retrospective study of pediatric cardiac patients experiencing death in ICU to review PPC presence and timing of initial PPC, most recent PPC, and interventions, therapies, CPR, and presence of do-not-resuscitate DNR discussion.

Eosinophils as modulators of host defense during parasitic, fungal, bacterial, and viral infections.

Eosinophils, traditionally associated as central innate effector cells with type 2 immunity during allergic and helminth parasitic diseases, have recently been revealed to have important roles in tissue homeostasis as well as host defense in a broader variety of infectious diseases. In a dedicated session at the 2023 biennial conference of the International Eosinophil Society titled "Eosinophils in Host Defense," the multifaceted roles eosinophils play against diverse pathogens, ranging from parasites to fungi, bacteria, and viruses, were presented. In this review, the session speakers offer a comprehensive summary of recent discoveries across pathogen classes, positioning eosinophils as pivotal leukocytes in both host defense and pathology.

Comparing the Use of Crotaline-Polyvalent Immune Fab (Ovine) Versus Observation in Children.

Objectives: In the United States, studies are inconclusive regarding the indications for polyvalent antivenom administration for crotaline envenomation. We compared polyvalent antivenom administration versus observation used at 2 separate institutions. We hypothesized that deferring antivenom leads to increased hospital length of stay and surgical interventions.

Tuberous Sclerosis Complex and the kidneys: what nephrologists need to know.

Tuberous sclerosis complex (TSC) is an autosomal dominant disease characterized by the development of hamartomas in the central nervous system, heart, skin, lungs, and kidneys and other manifestations including seizures, cortical tubers, radial migration lines, autism and cognitive disability. The disease is associated with pathogenic variants in the TSC1 or TSC2 genes, resulting in the hyperactivation of the mTOR pathway, a key regulator of cell growth and metabolism. Consequently, the hyperactivation of the mTOR pathway leads to abnormal tissue proliferation and the development of solid tumors.

Clinical practice recommendations for kidney involvement in tuberous sclerosis complex: a consensus statement by the ERKNet Working Group for Autosomal Dominant Structural Kidney Disorders and the ERA Genes & Kidney Working Group.

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by the presence of proliferative lesions throughout the body. Management of TSC is challenging because patients have a multifaceted systemic illness with prominent neurological and developmental impact as well as potentially severe kidney, heart and lung phenotypes; however, every organ system can be involved. Adequate care for patients with TSC requires a coordinated effort involving a multidisciplinary team of clinicians and support staff.

A Descriptive Analysis: Infants Presenting to the Pediatric Emergency Department With a Brief Resolved Unexplained Event.

Objectives: Infants presenting to pediatric emergency departments (EDs) after a choking episode, cyanotic event, or irregular breathing pattern are often diagnosed with a brief, resolved, unexplained event (BRUE). Social determinants of health may affect these patients; therefore, we aimed to define population demographics and determine significant demographic predictors between 2 cohorts-infants presenting with BRUE, and those admitted to the intensive care unit.

Methods: Using data from the Pediatric Health Information System (Children's Hospital Association, Washington, DC, Lenexa, KS), this multicenter, retrospective study included children aged 0-1 year from 52 hospitals who presented with an International Classification of Diseases-10 coded primary diagnosis for BRUE/apparent life-threatening event (ALTE) between January 1, 2016, and June 30, 2021.

Exploring the Regulation and Function of in the Development of Early-Onset Dilated Cardiomyopathy and Congestive Heart Failure Using Systems Genetics Approach.

Background: Cardiomyopathies, diseases affecting the myocardium, are common causes of congestive heart failure (CHF) and sudden cardiac death. Recently, biallelic variants in ribosomal protein L3-like (RPL3L) have been reported to be associated with severe neonatal dilated cardiomyopathy (DCM) and CHF. This study employs a systems genetics approach to gain understanding of the regulatory mechanisms underlying the role of in DCM.
