Using pharmacist-directed service improves quality of care for patients

2011-02-09
(Press-News.org) DETROIT ¬– A Henry Ford Hospital study has found that a pharmacist-directed anticoagulation service improves the way medication is managed for patients with heparin-induced thrombocytopenia (HIT), a common but life-threatening thromboembolic disorder.

Researchers found that patients treated by the anticoagulation service had a favorable response to alternative anticoagulant drugs three times faster and were 32 percent more likely to receive proper dosage than patients who were treated with the same drugs by the patient's primary medical team.

This is the first time researchers evaluated the impact of the anticoagulation service on the efficiency and safety of using a different class of anticoagulant drugs called direct thrombin inhibitors for treating patients with HIT, in which a patient's platelet count drops after they receive the anticoagulant drug heparin.

The study is to be published online Tuesday at www.theannals.com in the February issue of The Annals of Pharmacotherapy.

"Based on our findings, we believe this type of service is a valuable strategy for improving the quality of care of patients with HIT," says James Kalus, PharmD, senior clinical pharmacy manager at Henry Ford and senior author of the study.

It is estimated that up to 3 percent of patients exposed to various forms of heparin may develop HIT, which is commonly treated in hospitalized patients. If a decrease in a patient's platelet count is not treated quickly and efficiently, serious blood clots can develop.

Henry Ford sought to evaluate whether a pharmacist-directed anticoagulation service could impact the care or outcomes of 193 HIT patients who were treated using direct thrombin inhibitors lepirudin or argatroban between 2005 and 2009. Ninety-eight patients were managed by the anticoagulation service and 95 patients were managed by the primary medical team.

Dr. Kalus says the study's findings "represent real improvements in quality of care."

"The pharmacist-directed anticoagulation service is a viable approach to standardize the use of direct thrombin inhibitors for improving both the efficiency and safety of these complicated medications in an inpatient setting," he says.

### The study was funded by Henry Ford Hospital.

Increased levels of cardiac enzymes after heart bypass associated with increased mortality

2011-02-09
Researchers at Mount Sinai School of Medicine have found that even small amounts of damage to heart muscle during coronary artery bypass grafting (CABG) is associated with an increased risk of death, even among patients who initially do well following surgery. The study is published in the February 9 issue of the Journal of the American Medical Association (JAMA). Small elevations of troponin and creatine phosphokkinase – chemicals called enzymes that are released by heart muscle cells when they are damaged – have often been dismissed as unimportant. But Mount Sinai ...

Polar bear births could plummet with climate change

2011-02-09
University of Alberta researchers Péter Molnár, Andrew Derocher and Mark Lewis studied the reproductive ecology of polar bears in Hudson Bay and have linked declining litter sizes with loss of sea ice. The researchers say projected reductions in the number of newborn cubs is a significant threat to the western Hudson Bay polar-bear population, and if climate change continues unabated the viability of the species across much of the Arctic will be in question. Using data collected since the 1990s researchers looked at the changing length of time Hudson Bay is frozen ...

Turning bacteria against themselves

Turning bacteria against themselves
2011-02-09
Bacteria often attack with toxins designed to hijack or even kill host cells. To avoid self-destruction, bacteria have ways of protecting themselves from their own toxins. Now, researchers at Washington University School of Medicine in St. Louis have described one of these protective mechanisms, potentially paving the way for new classes of antibiotics that cause the bacteria's toxins to turn on themselves. Scientists determined the structures of a toxin and its antitoxin in Streptococcus pyogenes, common bacteria that cause infections ranging from strep throat to life-threatening ...

Speedy generic approval may not benefit consumers as much as expected, Rotman model shows

2011-02-09
Toronto – Faster approval times for generic drugs will get them into consumers' hands quicker, but may not make the price any better, a pricing and marketing researcher has found. A mathematical model created by Andrew Ching shows that fewer firms enter the marketplace because the chances of getting there first and commanding the best profits are dramatically smaller when drug approval times are shorter. Ching is an associate professor of marketing at the University of Toronto's Rotman School of Management. Using the drug clonidine, Prof. Ching's model showed the number ...

Combining brain imaging, genetic analysis may help identify people at early risk of Alzheimer's

2011-02-09
For Immediate Release – February 8, 2011 - (Toronto) – A new study from the Centre for Addiction and Mental Health (CAMH) has found evidence suggesting that a variation of a specific gene may play a role in late-onset Alzheimer's, the disease which accounts for over 90% of Alzheimer's cases. This innovative study has combined genetics and brain imaging to determine who may be at risk for developing late-onset Alzheimer's disease long before symptoms appear. The gene, which is called brain-derived neurotrophic factor (BDNF), is crucial to maintaining healthy function of ...

Eggs are now naturally lower in cholesterol

2011-02-09
Park Ridge, IL (February 8, 2011) – According to new nutrition data from the United States Department of Agriculture's Agricultural Research Service (USDA-ARS), eggs are lower in cholesterol than previously thought. The USDA-ARS recently reviewed the nutrient composition of standard large eggs, and results show the average amount of cholesterol in one large egg is 185 mg, 14 percent lower than previously recorded. The analysis also revealed that large eggs now contain 41 IU of vitamin D, an increase of 64 percent. "We collected a random sample of regular large shell eggs ...

Single-cell marine predator's unique survival mechanisms revealed: UBC research

2011-02-09
University of British Columbia researchers have uncovered the unique survival mechanisms of a marine organism that may be tiny, but in some ways has surpassed sharks in its predatory efficiency. Published today in the journal Nature Communications, the research team's portrait of the microscopic dinoflagellate Oxyrrhis marina reveals a predator so efficient that it has even acquired a gene from its prey. NB: A microscopic photo of Oxyrrhis marina is available at http://www.publicaffairs.ubc.ca/?p=17636. "It's an interesting case of Lateral Gene Transfer, or the movement ...

Hope for stroke victims

2011-02-09
Much of the devastation of stroke and head trauma is due to damage caused the overproduction of a substance in the brain called glutamate. Preventing this damage has been impossible, until now, as many drugs don't cross the so-called blood-brain barrier, and those that do often don't work as intended. But a method originally devised at the Weizmann Institute of Science may, in the future, offer a way to avert such glutamate-induced harm. Prof. Vivian I. Teichberg of the Institute's Neurobiology Department first demonstrated a possible way around these problems in 2003. ...

Turning off stress

2011-02-09
Post-traumatic stress disorder can affect soldiers after combat or ordinary people who have undergone harrowing experiences. Of course, feelings of anxiety are normal and even desirable – they are part of what helps us survive in a world of real threats. But no less crucial is the return to normal – the slowing of the heartbeat and relaxation of tension – after the threat has passed. People who have a hard time "turning off" their stress response are candidates for post-traumatic stress syndrome, as well as anorexia, anxiety disorders and depression. How does the body ...

Paper archives reveal pollution's history

2011-02-09
Some of the history preserved in old tomes and newspapers may be hiding in between the lines of print. A Weizmann Institute scientist has found that the paper in such collections contains a record of atmospheric conditions at the time the trees that went into making it were growing. By analyzing the carbon isotopes in bits of paper clipped from old magazines, Prof. Dan Yakir of the Environmental Sciences and Energy Research Department in the Faculty of Chemistry has traced the rising effects of atmospheric pollution from burning fossil fuel going back to beginnings of the ...
