Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA comparison of 5-day courses of dirithromycin and azithromycin in the treatment of acute exacerbations of chronic obstructive pulmonary disease.
Short-term use of antibiotics has become a common component of the management of acute exacerbations of chronic bronchitis (AECB), particularly in complex cases with productive cough or purulent phlegm. The macrolide antibiotics, particularly second-generation agents such as dirithromycin and azithromycin, are among the antibiotic classes frequently recommended and used to treat upper and lower respiratory infections, including AECB. ⋯ The results of this study suggest comparable clinical efficacy between 5-day courses of once-daily dirithromycin and azithromycin in acute exacerbations of COPD. There were insufficient data to permit meaningful comparison of the bacteriologic efficacy of these macrolide antibiotics.

Randomized Controlled Trial Comparative Study Clinical TrialGranisetron versus granisetron/dexamethasone combination for the treatment of nausea, retching, and vomiting after major gynecologic surgery: a randomized, double-blind study.
Granisetron, a selective 5-hydroxytryptamine3 antagonist, is effective for the treatment of patients with postoperative nausea and vomiting. Dexamethasone decreases chemotherapy-induced emesis when added to an antiemetic regimen. ⋯ In this study, the granisetron/dexamethasone combination was more effective than was granisetron alone for the management of nausea and vomiting during 0 to 3 hours after anesthesia in women undergoing major gynecologic surgery.

Review Comparative StudyA review of the effects of almotriptan and other triptans on clinical trial outcomes that are meaningful to patients with migraine.
Traditional end points in clinical trials of migraine therapy, such as 2-hour pain response, may not fully address the outcomes patients consider most important: rapid and sustained freedom from pain over 24 hours, and a low, placebo-like incidence of adverse events. A composite efficacy measure such as the sustained pain-free rate (no pain by 2 hours after dosing, no recurrence, no use of rescue medication from 2 to 24 hours after dosing) may be more appropriate. ⋯ Data from clinical trials suggest that almotriptan is effective and well tolerated in the treatment of acute migraine pain. Based on a sustained pain-free rate that is among the highest and an adverse-event rate that is among the lowest for the triptans, almotriptan represents a therapeutic option for the initial treatment of acute migraine with or without aura.

ReviewDrotrecogin alfa (recombinant human activated protein C) for the treatment of severe sepsis.
The search for a life-preserving drug to treat sepsis has increased understanding of the pathogenesis of the process but produced little in the way of successful treatments. The prospective, randomized, double-blind, placebo-controlled, Phase III, multicenter Recombinant Human Activated Protein C Worldwide Evaluation in Severe Sepsis (PROWESS) trial suggested that drotrecogin alfa--recombinant human activated protein C--significantly improved 28-day mortality rates in acute sepsis (P = 0.005). ⋯ Drotrecogin alfa is the first adjunctive agent for the treatment of sepsis to display clinically and statistically significant effects on mortality rates at 28 days. Many questions remain regarding which patients are ideal candidates for treatment. New research and treatment guidelines are necessary to address these questions.

ReviewOutcomes research related to patient decision making in oncology.
For outcomes research, what are the implications of seeing the patient as a decision maker? In the current medical environment, greater emphasis is placed on the role played by the patient in clinical decision making. In the past 2 decades, considerable work has been done to identify and measure decision-related outcomes, including knowledge about the treatment options (risks and benefits), satisfaction, anxiety, decisional conflict, and involvement in the decision process. ⋯ Future research is needed to understand which aspects of the interventions work and for what types of patients. Research is also needed to better understand the decision making process of patients who do not use decision aids.
