Review Meta Analysis
Meta-analysis of the efficacy and safety of adalimumab, etanercept, and infliximab for the treatment of rheumatoid arthritis.
To evaluate the efficacy and safety of using the anti-tumor necrosis factor-alpha (anti-TNF-alpha) drugs adalimumab, etanercept, and infliximab for the treatment of rheumatoid arthritis. ⋯ With short-term treatment, etanercept and adalimumab had higher efficacy results; with long-term treatment, adalimumab appeared to be the most effective. Clinicians should be aware that each of the three drugs has different rates of efficacy and different safety considerations that must be taken into account when selecting the best treatment for an individual with rheumatoid arthritis.

To evaluate the impact of inappropriate therapy--defined as delayed antifungal therapy beyond 24 hours from culture collection, inadequate antifungal dosage, or administration of an antifungal to which an isolate was considered resistant--on postculture hospital length of stay and costs, and to evaluate the relationship between modifiable risk factors, including failure to remove a central venous catheter, antifungal delay, and inadequate dosage, for an additive effect on hospital length of stay and costs. ⋯ Inappropriate therapy for Candida bloodstream infection occurring within 14 days of hospitalization was associated with prolonged postculture length of stay and increased costs. A rise in costs, but not length of stay, was noted with increasing modifiable risk factors.

Aneurysmal subarachnoid hemorrhage (SAH) accounts for a significant percentage of morbidity and mortality among patients admitted to neurosurgical centers throughout the world. Even for individuals surviving beyond the initial presentation and intervention for aneurysmal SAH, the occurrence of cerebral vasospasm has the potential to induce a second tier of complications that can be just as devastating as the inciting event. However, despite numerous studies and some initial advancements in management, therapeutic modalities are limited to help prevent or treat this complex entity. ⋯ Based on the currently available literature, it is impossible to assess the most effective intraarterial therapy. Randomized controlled trials that can control for baseline factors and technical expertise are needed to provide more conclusive data. Clinical pharmacists should be actively involved in assisting interventional radiologists and neurosurgeons in providing safe and appropriate pharmacotherapy in this promising but controversial arena of intraarterial drug delivery.

To evaluate the safety and economic impact of three models of anticoagulation management services: usual medical care, a nurse-managed service, and a pharmacist-managed service. ⋯ Pharmacist-managed anticoagulation management services reduced the rates of anticoagulation-related emergency department visits and hospitalizations, with significant financial impact. Based on results of this study, a collaborative clinic using pharmacists, nurses, and physicians may be the optimal structure for an anticoagulation management service, with these results verified in future prospective randomized studies.

Review Case Reports
Unfractionated heparin dosing for venous thromboembolism in morbidly obese patients: case report and review of the literature.
Unfractionated heparin infusion therapy is often administered using a weight-based dosing strategy for the treatment of venous thromboembolism. In the last several decades, the prevalence of obesity in the United States has increased significantly. The applicability of weight-based heparin dosing recommendations in the obese and morbidly obese population is uncertain, as limited data are available. ⋯ Standard weight-based heparin dosing protocols that specify maximum doses for initial bolus and infusion rates can result in significant delays in time to achieve therapeutic anticoagulation in the obese and morbidly obese patient. Despite limited data on heparin dosing in obesity, we recommend the use of a dosing weight to determine initial heparin dosing when treating venous thromboembolism in morbidly obese patients. It is reasonable to consider one of the following formulas: dosing weight = ideal body weight (IBW) + 0.3(actual body weight [ABW] - IBW), or dosing weight = IBW + 0.4(ABW - IBW).
