Venous thromboembolic disease, including deep vein thrombosis and pulmonary embolism, is a cause of significant mortality and morbidity. For several decades, anticoagulant options for the treatment and prevention of thrombosis have been limited mainly to agents such as unfractionated heparin and oral vitamin K antagonists, such as warfarin. ⋯ Specifically, progress has been made in the development of small molecule factor Xa inhibitors and thrombin inhibitors. With their potentially consistent and predictable clinical profile, oral formulation, and decreased need for coagulation monitoring, these new agents will likely increase the use and duration of anticoagulation treatment in thromboembolic disorders and reduce the burden associated with long-term management.

Comparative Study
Comparison of short-acting intramuscular antipsychotic medication: impact on length of stay and cost.
A retrospective cohort study was conducted to determine if there is an association between short-acting intramuscular (SAIM) antipsychotics used for acute agitation and length of stay (LOS). Patients with a diagnosis of schizophrenia or schizoaffective disorder who were dispensed at least one dose of a SAIM antipsychotic were divided into groups based on the initial SAIM antipsychotic received once admitted to a psychiatric unit. Electronic records were used to gather demographic information, LOS, and number of injections received during an admission. ⋯ Patient characteristics should be evaluated when determining an agent for acute agitation. However, because literature indicates second generation SAIM antipsychotics are only noninferior to haloperidol; other factors should also be evaluated; including impact on LOS and impact on hospital resources. This study indicates use of a second generation SAIM antipsychotic for acute agitation is more costly, requires more injections, and was not associated with a shorter length of stay when compared with SAIM haloperidol.

Zolpidem (trade name Ambien ®) is commonly prescribed. Case reports and popular media suggest potential dangers exist and may result in unanticipated complications. The primary aim was to determine how commonly zolpidem ingestion results in hospital evaluation and admission. ⋯ Associated with ICU admission were co-ingestion of over-the-counter medicines (OR 3.33, 95% CI, 1.93 to 5.76), other prescribed psychotropics (antidepressants or mood stabilizers) (OR 3.11, 95% CI, 2.21 to 4.39), or ethanol (OR 2.12, 95% CI, 1.36 to 3.32). When zolpidem is ingested with other medications or ethanol, admission to the ICU was common in our series. Despite its reported safely, zolpidem overdose often requires ICU admission from the ED, which is associated with ingestion of other pharmaceutical products or alcohol.

Randomized Controlled Trial Multicenter Study
Tramadol hydrochloride extended-release once-daily in the treatment of osteoarthritis of the knee and/or hip: a double-blind, randomized, dose-ranging trial.
This 12-week, multicenter, randomized, double-blind, placebo-controlled, dose-ranging trial evaluated tramadol ER (extended-release tramadol) in the management of osteoarthritis pain. Adults with knee and/or hip osteoarthritis and baseline pain intensity of ≥40 on a 100-mm visual analog scale (0 = no pain, 100 = extreme pain) received once-daily tramadol ER 100 mg (n = 201), 200 mg (n = 199), or 300 mg (n = 199), celecoxib 200 mg (n = 202; to test model sensitivity), or placebo (n = 200). Coprimary efficacy variables were Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale, WOMAC physical function subscale, and patient global assessment of disease activity. ⋯ Adverse events occurred more frequently with tramadol ER than placebo in the gastrointestinal (nausea, constipation, diarrhea) and central nervous (dizziness, headache) systems. In this study, tramadol ER 300 mg was effective in the management of moderate to severe painful osteoarthritis of the hip or knee. A large, increasing placebo response during the study may have contributed to the lack of statistical separation between tramadol ER 200 or 100 mg and placebo.

Meta Analysis Comparative Study
Comparison of low molecular weight heparin with unfractionated heparin during percutaneous coronary interventions: a meta-analysis.
To conduct a meta-analysis of the current evidence to evaluate the safety and efficacy of low molecular weight heparin (LMWH) as compared to unfractionated heparin (UFH). Several studies have demonstrated the therapeutic advantage of LMWH over UFH in the medical management of acute coronary syndromes. However, evidence comparing the 2 in percutaneous coronary interventions (PCI) is inconclusive. ⋯ A subgroup analysis of studies using intravenous or intraarterial administration of LMWH, demonstrated them to be safer than UFH with comparable efficacy. LMWH is at least as efficacious and safe as UFH in patients undergoing PCI. Additionally, evidence suggests that LMWH, when used intravenously, is associated with lower bleeding risks when compared with UFH.
