Personalizing Heart Failure Care to the Patient With Cancer.

Purpose Of Review: The current review describes the role of the cardio-oncology nurse and the need for personalized heart failure care for the patient with cancer.

Recent Findings: It is a new role whereby cardiology or heart failure nurses care for patients with cancer who develop cardiotoxicity or cardiovascular diseases, either during the cancer therapy or in a later stage. Inter-disciplinary approach is important for individualized early treatment, shortened interruptions to cancer therapy, and irreversible cardiovascular injury prevention.

Association between ethnicity and degree of improvement in cardiac function following initiation of sacubitril/valsartan.

Aims: The aim of this study was to determine the degree of short-term improvement in left ventricular ejection fraction (LVEF), haemodynamics, NT-proBNP and quality of life following initiation of sacubitril/valsartan in black patients when compared with white patients.

Methods: This was a retrospective, observational, single-centre, hypothesis-generating study of patients with symptomatic heart failure and reduced ejection fraction (HFrEF) treated with guideline recommended therapy, who were transitioned from an ACE inhibitor (ACE-I) or angiotensin receptor blocker (ARB) to sacubitril/valsartan.

Results: Our analysis included 83 patients (mean age 57 years) with echocardiography performed before and after transition from ACE-I/ARB to sacubitril/valsartan, after excluding patients with concomitant Cardiac resynchronization therapy implantation.

Interleukin-17A Serves a Priming Role in Autoimmunity by Recruiting IL-1β-Producing Myeloid Cells that Promote Pathogenic T Cells.

Interleukin-17A (IL-17A) is a major mediator of tissue inflammation in many autoimmune diseases. Anti-IL-17A is an effective treatment for psoriasis and is showing promise in clinical trials in multiple sclerosis. In this study, we find that IL-17A-defective mice or mice treated with anti-IL-17A at induction of experimental autoimmune encephalomyelitis (EAE) are resistant to disease and have defective priming of IL-17-secreting γδ T (γδT17) cells and Th17 cells.

Oxygen tension-mediated erythrocyte membrane interactions regulate cerebral capillary hyperemia.

The tight coupling between cerebral blood flow and neural activity is a key feature of normal brain function and forms the basis of functional hyperemia. The mechanisms coupling neural activity to vascular responses, however, remain elusive despite decades of research. Recent studies have shown that cerebral functional hyperemia begins in capillaries, and red blood cells (RBCs) act as autonomous regulators of brain capillary perfusion.

Loss of the molecular clock in myeloid cells exacerbates T cell-mediated CNS autoimmune disease.

The transcription factor BMAL1 is a core component of the molecular clock, regulating biological pathways that drive 24 h (circadian) rhythms in behaviour and physiology. The molecular clock has a profound influence on innate immune function, and circadian disruption is linked with increased incidence of multiple sclerosis (MS). However, the mechanisms underlying this association are unknown.
