Palliative care is a multidisciplinary approach to symptom management, psychosocial support, and assistance in treatment decision-making for patients with serious illness and their families. It emphasizes well-being at any point along the disease trajectory, regardless of prognosis. The term "palliative care" is often incorrectly used as a synonym for end-of-life care, or "hospice care". ⋯ However, patients with hematologic malignancies rarely utilize palliative care services, despite their many unmet palliative care needs, and are much less likely to use palliative care compared to patients with solid tumors. In this article, we will define "palliative care" and address some common misconceptions regarding its role as part of high-quality care for patients with cancer. We will then review the evidence supporting the integration of palliative care into comprehensive cancer care, discuss perceived barriers to palliative care in hematologic malignancies, and suggest opportunities and triggers for earlier and more frequent palliative care referral in this population.

For more than 3 decades, the scientific community has pursued gene correction of hemophilia, with the goal that an individual with congenitally deficient factor VIII or factor IX might synthesize adequate endogenous clotting factor to be relieved of burdensome repeated clotting factor infusions, as well as the emotional weight of continuous hemorrhage risk. Recent reports of successful factor IX gene therapy and partial correction of the bleeding phenotype have raised the bar for success for a robust crop of new clinical gene therapy efforts for both hemophilia A and B. ⋯ Human clinical trial progress is reviewed regarding a recombinant bispecific IgG antibody to factors IXa and X that mimics factor VIII cofactor activity, as well as monoclonal antibody and short interfering RNA strategies that demonstrate hemostatic efficacy via opposing inhibitors of coagulation. These strategies, associated with prolonged hemostatic potential following subcutaneous (ACE910, ALN-AT3, Concizumab) or single administration (eg, gene therapy) make it possible to imagine a day when recombinant clotting factor administration, rather than being a daily preoccupation, is relegated to an adjunctive role in supporting more novel standard of care therapies.

The lack of a strong evidence base to guide the management of adults with sickle cell disease (SCD) makes it difficult for patients to receive high quality care outside of specialty centers. As there is a dearth of providers with sickle cell expertise, the purpose of this article is to identify some of the key things every provider who manages the care of adults with SCD should know. ⋯ We have chosen topics for which there is a limited evidence base but which have significant clinical consequences if left unrecognized or poorly managed. The topics that will be addressed include chronic pain, neurocognitive dysfunction, renal disease, venous thromboembolism, and avoiding the inappropriate use of red cell transfusions.

Liver disease results in complex alterations of all 3 phases of hemostasis. It is now recognized that hemostasis is rebalanced in chronic liver disease. The fall in clotting factor levels is accompanied by a parallel fall in anticoagulant proteins. ⋯ Bacterial infection may impair hemostasis in cirrhosis by triggering the release of endogenous heparinoids. There are no evidence-based guidelines for hemostatic therapy of acute hemorrhage in liver disease. There is currently inadequate evidence to support the use of recombinant FVIIa, prothrombin complex concentrates, or tranexamic acid in acute variceal or other hemorrhage.
