Delirium impedes communication and contributes to symptom distress in patients with advanced cancer. There are few prospective data on the reversal of delirium in this population. ⋯ Delirium is a frequent, multifactorial complication in advanced cancer. Despite its terminal presentation in most patients, delirium is reversible in approximately 50% of episodes. Delirium precipitated by opioids and other psychoactive medications and dehydration is frequently reversible with change of opioid or dose reduction, discontinuation of unnecessary psychoactive medication, or hydration, respectively.

Risk factors for deep vein thrombosis and pulmonary embolism: a population-based case-control study.
Reported risk factors for venous thromboembolism (VTE) vary widely, and the magnitude and independence of each are uncertain. ⋯ Hospital or nursing home confinement, surgery, trauma, malignant neoplasm, chemotherapy, neurologic disease with paresis, central venous catheter or pacemaker, varicose veins, and superficial vein thrombosis are independent and important risk factors for VTE.

Randomized Controlled Trial Clinical Trial
Around-the-clock, controlled-release oxycodone therapy for osteoarthritis-related pain: placebo-controlled trial and long-term evaluation.
Although opioid analgesics have well-defined efficacy and safety in treatment of chronic cancer pain, further research is needed to define their role in treatment of chronic noncancer pain. ⋯ Around-the-clock controlled-release oxycodone therapy seemed to be effective and safe for patients with chronic, moderate to severe, osteo-arthritis-related pain. Effective analgesia was accompanied by a reduction in the interference of pain with mood, sleep, and enjoyment of life. Analgesia was maintained during long-term treatment, and the daily dose remained stable after titration. Typical opioid side effects were reported during short- and long-term therapy.

The recurrence rate after deep vein thrombosis (DVT) is high and the risk factors for recurrent thromboembolic events have only been investigated on a small scale. ⋯ The recurrence rate after a symptomatic DVT is high. Patients with proximal DVT, diagnosed cancer, short duration of oral anticoagulation therapy, or a history of thromboembolic events had a higher risk of recurrent events, while patients with postoperative DVT had a lower recurrence rate. This knowledge could help identify patients who might benefit most from prolonged prophylactic treatment in various risk situations.

Meta Analysis
Angiotensin-converting enzyme inhibitor-associated elevations in serum creatinine: is this a cause for concern?
Reducing the actions of the renin-angiotensin-aldosterone system with angiotensin-converting enzyme inhibitors (ACEIs) slows nephropathy progression in patients with or without diabetes. Post hoc analyses of many ACEI-based clinical trials demonstrate the greatest slowing of renal disease progression in patients with the greatest degree of renal insufficiency at study initiation. However, many physicians fail to use ACEIs or angiotensin receptor blockers in patients with renal insufficiency for fear that either serum creatinine or potassium levels will rise. ⋯ A strong association exists between acute increases in serum creatinine of up to 30% that stabilize within the first 2 months of ACEI therapy and long-term preservation of renal function. This relationship holds for persons with creatinine values of greater than 124 pmol/L (>1.4 mg/dL). Thus, withdrawal of an ACEI in such patients should occur only when the rise in creatinine exceeds 30% above baseline within the first 2 months of ACEI initiation, or hyperkalemia develops, ie, serum potassium level of 5.6 mmol/L or greater.
