Palliative medicine provides active evaluation and treatment of the physical, psychosocial and spiritual needs of patients and families with serious illnesses, regardless of curability or stage of illness. The hematologic malignancies comprise diverse clinical presentations, evolutions, treatment strategies and clinical and quality of life outcomes with dual potential for rapid clinical decline and ultimate improvement. While recent medical advances have led to cure, remission or long-term disease control for patients with hematologic malignancy, many still portend poor prognoses and all are associated with significant symptom and quality of life burden for patients and families. ⋯ Palliative care teams provide an additional layer of support to patients, family caregivers, and the primary medical team through close attention to symptoms and emotional, practical, and spiritual needs. Barriers to routine palliative care co-management in hematologic malignancies include persistent health professional confusion about the role of palliative care and its distinction from hospice; inadequate availability of palliative care provider capacity; and widespread lack of physician training in communicating about achievable goals of care with patients, family caregivers, and colleagues. We herein review the evidence of need for palliative care services in hematologic malignancy patients in the context of a growing body of evidence demonstrating the beneficial outcomes of such care when provided simultaneously with curative or life-prolonging treatment.

The innate immune system orchestrated by leukocytes primarily neutrophils, serves to remove dead and dying host cells and to provide protection against invasion by pathogens. Failure of this system results in the onset of sepsis leading to grave consequences for the host. Together with mechanical methods to physically isolate and remove the pathogen, neutrophils also release an important set of proinflammatory biological modulators that mediate recruitment of additional cells to a site of infection and amplify the innate protective response. ⋯ NETs also contain the neutrophil secretary granule-derived serine proteases, neutrophil elastase and cathepsin G, known to regulate the reactivity of both neutrophils and platelets. Since the characterization of NETs in 2004, new studies of their functional effect in vivo continue to expand upon unexpected extracellular roles for DNA, and in doing so renew attention to the haemostatic role of the leukocyte. This review will provide a basic description of NETs and examine current knowledge of this important system of defense, including recent work illustrating a role for NETs in activation of thrombosis.
