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.

Obstetric hemorrhage remains a leading cause of maternal morbidity and mortality worldwide. Many postpartum hemorrhages (PPHs) do not have identifiable risk factors; maternity units should therefore have obstetric hemorrhageprotocols in place for all parturients as every pregnancy has the potential to be complicated by hemorrhage. This review will examine the epidemiology of PPH as well as current recommendations for key elements in obstetric hemorrhage protocols. Recent advances in hematologic management of PPH will be also be reviewed, including: (1) recognition of hypofibrinogenemia as a risk factor for severe PPH, (2) use of antifibrinolytic therapy, and (3) strategies for fibrinogen replacement therapy.

Despite many recent advances in the treatment of multiple myeloma, the course of the disease is characterized by a repeating pattern of periods of remission and relapse as patients cycle through the available treatment options. Evidence is mounting that long-term maintenance therapy may help suppress residual disease after definitive therapy, prolonging remission and delaying relapse. For patients undergoing autologous stem cell transplantation (ASCT), lenalidomide maintenance therapy has been shown to improve progression-free survival (PFS); however, it is still unclear whether this translates into extended overall survival (OS). ⋯ Other trials have also investigated thalidomide and bortezomib maintenance for ASCT patients, and both agents have been evaluated as continuous therapy for those who are ASCT ineligible. However, some important questions regarding the optimal regimen and duration of therapy must be answered by prospective clinical trials before maintenance therapy, and continuous therapy should be considered routine practice. This article reviews the available data on the use of maintenance or continuous therapy strategies and highlights ongoing trials that will help to further define the role of these strategies in the management of patients with newly diagnosed multiple myeloma.

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.

Small-molecule kinase inhibitors, especially the two Food and Drug Administration-approved agents idelalisib and ibrutinib, have changed the treatment landscape for patients with relapsed or refractory chronic lymphocytic leukemia (CLL). However, with these positive changes comes the new challenge of managing patients who relapse after these agents. The number of patients who have relapsed after taking idelalisib and ibrutinib is low, but as the drugs gain wider use and patients are treated for longer, this number is likely to grow. ⋯ As well, identification of mechanisms of resistance is crucial to develop rational strategies for management. Current work has identified mechanisms of resistance to ibrutinib, and resistance to idelalisib is also under active investigation. In this review, we will discuss these mechanisms of resistance, as well as current and potential strategies for the management of kinase inhibitor-resistant CLL.
