EditorialPrediction of treatment outcomes in major depressive disorder.
Improving the treatment of major depressive disorder will require identification of moderators that predict differential outcomes across treatments at the level of the individual patient, referred to as precision medicine. Currently, there are no biological measures demonstrated to enhance treatment selection accuracy although there are some clinical variables that have prognostic value. ⋯ Genetic combination tests, systemic inflammation, electroencephalography and neuroimaging, in particular, show significant potential for near-term development as clinically meaningful moderators for use in treatment selection. Ultimately, combinations of moderators may provide the greatest level of precision in selecting optimal treatment approaches for individual depressed patients.

EditorialFactors to consider in the choice of intrathecal drug in the treatment of neuropathic pain.
Medication selection for neuropathic pain follows a path of evidence, with respect to appreciating the patient's entry into the pain care algorithm. As we decide how to approach neuropathic pain, the considerations for intrathecal therapy medication selection are bound by catheter location, region of pain, and patient selection, to name a few. Future research and the 2016 polyanalgesic consensus conference may further provide patient care through a mindful eye on the improvement of patient safety and a reduction of the societal needs of opioids.

ReviewFentanyl buccal tablet for the treatment of cancer-related breakthrough pain.
Fentanyl buccal tablet (FBT) (FENTORA) is indicated for the management of breakthrough pain (BTP) in patients with cancer pain and who are tolerant to ≥60 mg of oral morphine equivalents, at least with the current availability of the minimal strength of 100 μg. FBT uses the OraVescent technology to further increase the rate and extent of absorption of fentanyl. ⋯ It has been recommended that administration should be tailored to the patient's individual requirement, through dose titration starting from the lowest dose to find the effective dose. However, recent studies have demonstrated that predictable doses calculated from the basal opioid regimen are safe and more effective than doses achieved after dose titration.

ReviewDabrafenib in combination with trametinib for the treatment of metastatic melanoma.
Oncogenic BRAF mutations are present in approximately 40-50% of patients with metastatic melanoma. Targeting BRAF mutations with either small molecule inhibitors of BRAF or one of the downstream mediators of oncogenic BRAF - MEK - is associated with improved outcomes compared with chemotherapy and has led to the US FDA approval of two BRAF inhibitors - vemurafenib and dabrafenib - and the MEK inhibitor trametinib. Further, the combination of dabrafenib and trametinib is well tolerated and associated with higher responses and improved survival compared with single-agent BRAF inhibitors.

ReviewKey findings from studies of methotrexate tapering and withdrawal in rheumatoid arthritis.
Methotrexate is the dominant initial drug in the management of rheumatoid arthritis (RA). Despite its widespread use, methotrexate is associated with a number of adverse effects. ⋯ This review examines studies of methotrexate tapering and withdrawal on RA outcomes. It covers three scenarios: tapering/withdrawing methotrexate monotherapy; tapering/withdrawing methotrexate as part of a 'step-down' combination disease-modifying anti-rheumatic drug regimen; and tapering/withdrawing methotrexate when it is being co-prescribed with biologic agents.
