The pathophysiology, clinical presentation, and natural history of acute pain in sickle cell disease are unique and require a disease-centered approach that also applies general principles of acute and chronic pain management. The majority of acute pain episodes are managed at home without the need to access health care. The long-term consequences of poorly treated acute pain include chronic pain, adverse effects of chronic opioid usage, psychological maladjustment, poor quality of life, and excessive health care utilization. ⋯ Pain management in the emergency department often does not meet acceptable standards, while chronic use of strong opioids is likely to result in opioid-induced hyperalgesia, exacerbation of chronic pain symptoms, and opioid dependency. We suggest that an integrated approach is needed to control the underlying condition, modify psychological responses, optimize social support, and ensure that health care services provide safe, effective, and prompt treatment of acute pain and appropriate management of chronic pain. This integrated approach should begin at an early age and continue through the adolescent, transition, and adult phases of the care model.

Pain is the leading cause of emergency department (ED) visits for individuals living with sickle cell disease (SCD). The care that is delivered in the ED is often cited by patients with SCD as the area of health care in greatest need of improvement. In 2014, the National Heart, Lung, and Blood Institute released guidelines for the care of SCD, including recommendations for the management of acute sickle cell pain in the ED. ⋯ Presented in this article are 4 tenets of implementing guideline-adherent emergency sickle cell care gleaned from the available literature and continuous quality improvement efforts at our institution. These include: (1) strategies to reduce negative provider attitudes toward patients with SCD; (2) strategies to reduce time-to-first-dose of analgesic medication; (3) strategies to improve ED pain care beyond the first dose of medication; and (4) strategies to improve ED patient safety. Application of the principles discussed within can improve patient and provider satisfaction, quality, and safety.

Multiple myeloma is the second most frequent hematological disease. The introduction of melphalan as high-dose therapy followed by autologous hematopoietic cell transplantation (HDT/ASCT) for young patients and the availability of novel agents for young and elderly patients with multiple myeloma have dramatically changed the perspective of treatment. However, further research is necessary if we want definitively to cure the disease. ⋯ For elderly patients, treatment options were once limited to alkylators, but new upfront treatment combinations based on novel agents (proteasome inhibitors and immunomodulatory drugs) combined or not with alkylators have significantly improved outcomes. Extended treatment of young and elderly patients improves the quality and duration of clinical responses; however, the optimal scheme, appropriate doses, and duration of long-term therapy have not yet been fully determined. This review summarizes progress in the treatment of patients with newly diagnosed multiple myeloma, addressing critical questions such as the optimal induction, early vs late ASCT, consolidation and/or maintenance for young patients, and how we can choose the best treatment option for non-transplant-eligible patients.

Direct oral anticoagulants (DOACs) have at least noninferior efficacy compared with other oral anticoagulants and have ancillary benefits, including overall better safety profiles, lack of the need for routine monitoring, rapid onset of action, and ease of administration. Reversal of these agents may be indicated in certain situations such as severe bleeding and for perioperative management. DOAC-associated bleeding should be risk stratified: patients with moderate or severe bleeding should have the DOAC discontinued and reversal strategies should be considered. ⋯ Nonspecific reversal agents should be considered only in the event of severe bleeding because their efficacy is unknown, and they are associated with risk of thrombosis. Recent results from phase 3/4 studies demonstrate efficacy for an antidote to dabigatran (idarucizumab, a monoclonal antibody fragment with specificity for dabigatran) and an antidote to factor Xa inhibitors (andexanet alfa, a recombinant and inactive form of factor Xa that binds inhibitors). A universal reversal agent (ciraparantag) for many anticoagulants, including the DOACs, shows promise in results from phase 1 and 2 studies.

Treating Hodgkin lymphoma by using chemotherapy with or without radiotherapy is highly successful, with substantially fewer deaths from lymphoma than from other causes in recent studies of both early-stage and advanced-stage disease. Long-term toxicity is a major consideration in this context, and recent trials have used functional imaging with [18F]fluorodeoxyglucose (FDG) positron emission tomography early in the course of treatment (interim PET) to assess response and modulate subsequent therapy. In early-stage disease, this has allowed omission of consolidation radiotherapy after a good response to doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) chemotherapy, and trials have shown that this can be done without detriment to overall survival, despite a small increase in rates of recurrence of ∼5%. ⋯ De-escalation by omission of bleomycin and consolidation radiotherapy after a negative interim PET scan seems safe with no increase in recurrence rate, but the performance of interim PET after ABVD is suboptimal, especially for those with very advanced disease at presentation; recurrence rates after a negative scan are ∼15%. The negative predictive value of PET is higher after escalated BEACOPP chemotherapy, and the approach of initially treating with BEACOPP and de-escalating to ABVD for those with negative interim PET scans shows promising early results. Response-adapted therapy has yielded important results for patients with Hodgkin lymphoma and is becoming established as a standard approach.
