CommentPercutaneous coronary intervention with drug-eluting stents or coronary artery bypass surgery in subjects with type 2 diabetes.
There is a debate as to whether percutaneous coronary intervention (PCI) with drug-eluting stents or coronary artery bypass surgery (CABG) is the best procedure for subjects with type 2 diabetes and coronary artery disease requiring revascularization. There is some evidence that by following these procedures, there is less further revascularization with CABG than PCI in subjects with diabetes. ⋯ However, the rates of stroke may be higher with CABG than PCI with drug-eluting stents in this population. Thus, if CABG is going to be preferred to PCI in subjects with type 2 diabetes and multivessel coronary disease, consideration should be given as to how to reduce the rates of stroke with CABG.

Ziconotide is an N-type calcium channel antagonist to treat chronic pain that is delivered intrathecally. It is the only intrathecal, FDA-approved, non-opioid analgesic and is recommended as first-line therapy. Despite these advantages, a small therapeutic window limits ziconotide's clinical utility, with adverse event (AE) challenges that include, but are not limited to, dizziness, nausea, and somulence. ⋯ Ziconotide is a safe and effective strategy to treat chronic pain, although limitations remain, including a small therapeutic window. Low starting doses and slow incremental increases and long titration intervals may improve tolerability. AEs may be mitigated by also employing combination therapy, although further study is needed. Concomitant use of ziconotide and morphine is an option when considering use of FDA-labeled intrathecal drugs in those resistant to monotherapy.

The lipid lowering class of drugs known as "Statins" are being increasing recognized for their pleiotropic effects which include anti-inflammation, antioxidant, vasodilatation, improved endothelial function and stabilization of atherosclerotic plaques. These effects may counteract, to some extent, the deleterious impact of surgical stress on various organ systems during the perioperative period. ⋯ Current evidence supports a reduction in cardiovascular morbidity and mortality associated with perioperative statin use in high risk patients undergoing non cardiac surgery and this represents a very cost effective application of statin therapy with few adverse events reported. Data is emerging that point to other benefits such as renal protection but this requires further confirmation from prospective studies. Future research needs to address the questions of the optimal type, timing and dosage of statin therapy as well as whether there are problems associated with abrupt withdrawal and adverse effects associated with long term use.

ReviewMilnacipran for fibromyalgia: a useful addition to the treatment armamentarium.
Antidepressants are used to treat a variety of chronic pain conditions including peripheral neuropathy, headache, and more recently, fibromyalgia. The antidepressant milnacipran blocks the reuptake of norepinephrine and serotonin and is used for the management of fibromyalgia. ⋯ Milnacipran provides modest fibromyalgia pain relief and is best used as part of a multidisciplinary treatment approach. While milnacipran was not studied in fibromyalgia patients with major depression, it may be a wise choice for fibromyalgia patients with depressive symptoms and patients for whom sedation, dizziness, edema or weight gain with gabapentin and pregabalin is a problem. Milnacipran has been found to be beneficial for treating some troublesome fibromyalgia-associated symptoms, including fatigue and cognitive dysfunction.

ReviewPeginesatide for the treatment of renal disease-induced anemia.
Erythropoiesis-stimulating agents (ESAs) are the mainstay of treatment in anemic chronic kidney disease (CKD) patients. A tailored ESA therapy should combine maximal efficacy and safety with greatest convenience in dosing. Peginesatide, recently approved in the US for once-monthly dosing in adult patients on dialysis, is a promising novel PEGylated erythropoietin-mimetic peptide for the treatment of renal disease-induced anemia. ⋯ Peginesatide has a well-studied pharmacological and immunological profile, and latest published data favor the use of peginesatide in place of epoetin in dialysis patients. A more detailed evaluation of its safety profile particularly in trials with CKD patients not requiring dialysis is urgently needed, as peginesatide could be a perfect treatment solution for these patients. In addition, clinical long-term data and results from supplemental studies, e.g., with the PEGylated continuous erythropoietin receptor activator as comparator, should briefly follow. The fate of peginesatide on the highly competitive ESA market is currently not predictable and depends on safety and efficacy results of upcoming trials as well as finally on market and price policy.
