ReviewNovel pharmacotherapy for burn wounds: what are the advancements.
The prognosis for severe burns has improved significantly over the past 50 years. Meanwhile, burns have become an affliction mainly affecting the less well-developed regions of the world. Early excision and skin grafting has led to major improvements in therapeutic outcomes. ⋯ Advancements in personalized and molecular medicine will make an impact on burn therapy. Similarities between severe burns and other critically ill patients will lead to cross-fertilization between different medical specialties. Furthermore, advances in stem cells and tissue regeneration will lead to improved healing and less lifelong disability. Indeed, research in new drug therapy for burns is actively progressing for many different complications.

Review Case ReportsAn evaluation of pixantrone for the treatment of non-Hodgkin's lymphoma.
The overall prognosis for patients with relapsed or refractory aggressive non-Hodgkin's lymphomas is poor. Only a minority of patients are able to receive autologous stem cell transplantation. Patients not transplant-eligible or patients relapsing after transplantation have an urgent need for effective treatment options. ⋯ Furthermore, the similarities and differences between pixantrone and anthracyclines is highlighted, with a special focus on the mode of action and on cardiotoxicity. Expert opinion: Pixantrone is a valuable treatment option in relapsed and refractory aggressive lymphomas, with documented disease responses, manageable toxicities and clear distinctions to anthracyclines. Additional studies are needed to evaluate the role of pixantrone in combination with other compounds, especially with upcoming targeted therapies, and to confirm the effectiveness of pixantrone in other lymphoma subtypes, e.g. follicular lymphomas.

Brexpiprazole: a step forward for precision medicine in resistant depression.
Resistant depression is still a common and burdensome issue and there is an urgent need for new and effective adjunctive treatments. Areas covered: In this paper, the author discusses the background, trial design, results and implications of a recent study (NCT02196506, Sirius study) which confirmed the possible benefit of brexpiprazole as adjunctive treatment in depressed subjects with inadequate benefit from first line treatments. ⋯ Expert opinion: The unique pharmacodynamic profile of brexpiprazole, in terms of reduced dopamine intrinsic stimulation and a range of other more anxiolytic receptor effects, suggests that brexpiprazole should be preferred in specific subpopulations, particularly where a more sedative profile is needed. Indeed, this study suggests another step in the direction of precision medicine.

ReviewDo glucagon-like peptide-1 receptor (GLP-1R) agonists have potential as adjuncts in the treatment of type 1 diabetes?
Glucagon-like peptide-1 (GLP-1) is produced by the gut, stimulates insulin secretion from the pancreatic β-cells, and inhibits glucagon secretion from the α-cells. The GLP-1 receptor (GLP-1R) agonists are used in the treatment of type 2 diabetes (T2DM). ⋯ GLP-1R agonists are unable to increase insulin secretion, in subjects with T1DM, who are C-peptide negative. Also, the GLP-1R agonists either have no effect or cause a small inhibition of glucagon secretion in subjects with T1DM. There is no evidence that the GLP-1R agonists cause a major reduction in HbA1c, or have a major effect on hypo- or hyperglycemia in subjects with TD1M. The main beneficial effect of the GLP-1R agonists is probably the modest weight loss, which may underlie the reduction in dose of insulin used. Given that the GLP-1R agonists cause gastrointestinal adverse effects, and with reduced insulin doses, increase the risk of ketosis, it seems to me that the risk with these agents may outweigh any benefit in T1DM, and that they have little potential as adjuncts in the treatment of T1DM.

ReviewCangrelor for the treatment of patients with Arterial Thrombosis.
All oral P2Y12 receptor blockers are associated with some degree of delayed onset and offset of pharmacodynamic (PD) effects in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI). Although intravenous glycoprotein IIb/IIIa inhibitors are associated with rapid onset of action, they are also associated with delayed offset and other limitations such as elevated bleeding risk and thrombocytopenia. Areas covered: In this review, the authors focus on cangrelor, an intravenous, reversible P2Y12 receptor blocker with fast onset and offset of effects. ⋯ Expert opinion: In ACS patients undergoing PCI, cangrelor is most desirable to effectively prevent periprocedural ischemic events and to avoid excessive bleeding. Indeed, any high-risk patient with ST-segment elevation myocardial infraction or patient who is unable to take oral medications is a potential candidate for intravenous cangrelor therapy. Furthermore, stable patients with coronary artery disease, who are considered for ad hoc PCI following coronary angiography, may be considered for treatment with cangrelor to reduce post-PCI thrombotic events.
