Two randomized, controlled trials published in the New England Journal of Medicine (NEJM) demonstrate that posaconazole may be considered a first-line option for prophylaxis of fungal infections in patients with severe graft versus host disease (GVHD) after allogeneic hematopoietic stem-cell transplantation as well as in immunosuppressed patients undergoing chemotherapy for acute myelogenous leukemia or the myelodysplastic syndrome.
In a randomized, double-blind, parallel-group trial published in the American Journal of Respiratory and Critical Care Medicine, the combination of fluticasone and salmeterol (SAL) statistically significantly reduced the number of chronic obstructive pulmonary disease (COPD) exacerbations by 35% compared with SAL alone.
Two studies published in the journals Lancet (Elliott et al) and the Archives of Internal Medicine (Barzilay et al) help to answer questions about the effect some antihypertensive agents can have on the development of diabetes mellitus, but these studies have also raised some new concerns about cardiovascular disease.
In a multi-center, randomized, double-blind, controlled trial, use of rosiglitazone in patients with type 2 diabetes was found to delay the progression to monotherapy failure (fasting plasma glucose >180 mg/dL) more effectively than using metformin or glyburide.
In a large, multi-center, randomized, open-label, prospective trial named the Acute Catheterization and Urgent Intervention Triage Strategy (ACUITY) trial, monotherapy with the anti-thrombotic agent bivalirudin, when administered to patients experiencing an acute coronary syndrome (ACS) (eg, unstable angina or myocardial infarction without ST-segment elevation), was demonstrated to be as efficacious as the current standard-of-care therapy but with nearly a 50% lower risk of bleeding. The results of the trial were published in the New England Journal of Medicine (NEJM).
Aprotinin has demonstrated a 48% increase in the risk of 5-year mortality following coronary artery bypass graft (CABG) surgery, according to a study published in the Journal of the American Medical Association (JAMA).

Many Americans suffer from insomnia regularly, but clinicians often do not address this issue. A variety of factors may contribute to insomnia, including medical conditions such as gastroesophageal reflux disease, Parkinson disease, and heart failure. Medications such as amphetamines, theophylline, and beta agonists could also precipitate insomnia.
Combination therapy with an antimuscarinic agent (tolterodine extended release [ER]) and alpha1-receptor antagonist (tamsulosin) provided symptomatic benefit in men with moderate-to-severe lower urinary tract symptoms and overactive bladder, according to a large-scale, randomized, double-blind, placebo-controlled study published in the Journal of the American Medical Association (JAMA).

A public forum scheduled this month will help to solidify proposals FDA unveiled in January for reauthorization of the Prescription Drug User Fee Act (PDUFA). Once public comment from the February 16 meeting is received and incorporated into the finalized proposal, negotiations between the agency and the federal government over the fourth incarnation of this important funding mechanism will be key in determining FDA's fiduciary future.
Researchers at the Infectious Disease Laboratory at Columbia University Mailman School of Public Health and the World Health Organization (WHO) Global Laboratory Network have developed a new diagnostic tool called the "GreeneChip," a glass slide that can rapidly and accurately identify multiple pathogens from different biologic samples (eg, tissue, blood, urine).
Direct-to-consumer advertising (DTCA) of prescription drugs has been a source of debate since its US approval by FDA in 1997. A primary source of debate among experts is the methods advertisers use to attempt to influence the consumer and the consumer's subsequent reaction. Despite the controversy, authors of a recent content analysis of televised DTCA say there has been no systematic analysis of DTCA's influence on consumers to date.
The American Gastroenterological Association (AGA) has issued a consensus statement on the safe and efficacious use of nonsteroidal anti-inflammatory drugs (NSAIDs), including nonselective, nonsteroidal anti-inflammatory drugs (nsNSAIDs), cyclooxygenase-2 enzyme inhibitors (coxibs), and aspirin (ASA).
A cross-sectional study of selective serotonin reuptake inhibitor (SSRI) use by community-dwelling older women aged ≥71 years with or without depression demonstrated that SSRI use in that population was strongly associated with sleep disturbance. The study, which relied on data collected from 4 centers throughout the United States, was recently published in the Journal of the American Geriatrics Society.
Adverse events associated with the use of atypical antipsychotic medications in the management of psychosis, aggression, and agitation in patients with Alzheimer's disease (AD) may outweigh any benefit the treatments provide, according to a double-blind, placebo-controlled study published in the New England Journal of Medicine (NEJM).
Rifaximin has demonstrated global improvement of the symptoms of irritable bowel syndrome (IBS) in patients for ≤10 weeks after the discontinuation of therapy. Rifaximin is a nonabsorbed (≤0.4%), broad-spectrum antibiotic that was approved by FDA in 2004 for travelers' diarrhea.
A post-hoc analysis of the large, randomized, double-blind, placebo-controlled Physicians' Health Study found that the use of low-dose aspirin (ASA) on alternating days reduced the risk of adult-onset asthma by a statistically significant 22%.
A randomized, double-blind, placebo-controlled trial published in the Journal of the American Medical Association (JAMA) found that women who discontinued alendronate after 5 years demonstrated a moderate decline in bone mineral density (BMD) and a gradual increase in serum markers of bone turnover compared with women who continued taking alendronate for an additional 5 years, but mean levels among patients who discontinued therapy remained at or above baseline levels measured 10 years earlier. In addition, no greater fracture risk other than for clinically detected vertebral fractures was seen in the discontinuation group compared with patients who continued alendronate for 10 years.
