Gut bacteria may affect whether a statin drug lowers cholesterol
Statins can be effective at lowering cholesterol, but they have a perplexing tendency to work for some people and not others. Gut bacteria may be the reason. A research team led by a Duke University scientist has identified three bile acids produced by gut bacteria that were evident in people who responded well to a common cholesterol-lowering drug called simvastatin. The finding, published Oct. 13, 2011, in PLoS One, demonstrates how gut bacteria can cause inherent differences in the way people digest, metabolize and benefit from substances such as drugs. The study represents the intersection of two emerging research interests: An analysis of the intestinal microflora, plus the use of a science called metabolomics, which examines the thousands of biochemical components involved in cellular metabolism and how they affect health

Citalopram: Health Canada reviewing dose-related heart risk
Health Canada is reviewing the heart-related safety of the prescription antidepressant citalopram. The review is in light of new study data suggesting that high doses (60 mg/day) can affect the electrical activity of the heart. The changes in electrical activity could potentially lead to serious, possibly fatal abnormal heart rhythms.
Health Canada is currently reviewing the available data and assessing the need for revised dosing recommendations and will take appropriate action based on the outcome of our review, including working with the companies to update the prescribing information. New safety information will be communicated to healthcare professionals and the public as soon as possible, once the review is complete.
Citalopram is used to treat depression and belongs to a family of drugs known as SSRIs (Selective Serotonin Reuptake Inhibitors). The current Canadian prescribing information recommends 20 mg/day of citalopram in adults. Some people who have not responded to this dose are prescribed 40 or even 60 mg/day.
In Canada, citalopram is available in 10, 20, 30, and 40 mg tablets. It is sold under the brand name Celexa and under several generic names (all of which contain "citalopram" in the name, except the generic products "ran-citalo" and "CTP 30")

FDA OKays combo pill for diabetes, cholesterol
The FDA has approved a fixed-dose combination tablet that combines the diabetes drug sitagliptin with simvastatin, under the brand name Juvisync. It's the first product with drugs for diabetes and high cholesterol in a single pill, the agency noted. Sitagliptin is a DPP-4 inhibitor sold as Januvia, first approved in 2006 as an adjunct to diet and exercise. Simvastatin (Zocor) is one of the most popular statin drugs for reducing total and LDL cholesterol. In the short term, the combination product will come in three strengths, all with 100 mg of sitagliptin and 10, 20, or 40 mg of simvstatin. The FDA advised physicians to consider other drugs that patients may be taking when deciding which strength to prescribe. The product's manufacturer, the Merck subsidiary MSD International GmbH Clonmel, of Tipperary, Ireland, has committed to develop additional strengths with 50 mg of sitagliptin and 10, 20, and 40 mg of simvastatin, according to the agency. "Pending availability of the fixed-dose combination tablets containing 50 mg of sitagliptin, patients who require this dose should continue to use the single ingredient sitagliptin tablet," the FDA said. Sitagliptin is also sold in a 25-mg dose, but it is seldom prescribed and there are no plans to develop Juvisync tablets with that dose, the agency added. The FDA noted that statins can exacerbate hyperglycemia in patients with type 2 diabetes. "This risk appears very small and is outweighed by the benefits of statins for reducing heart disease in diabetes," the agency said. "However, the prescribing information for Juvisync will inform doctors of this possible side effect. The company will also be required to conduct a post-marketing clinical trial comparing the glucose-lowering ability of sitagliptin alone compared to sitagliptin given with simvastatin." Common side effects associated with the combination include upper respiratory infections, rhinitis, sore throat, headache, muscle and stomach pain, constipation, and nausea.

Canada's emergency doctors push to improve rate of "bystander" CPR assistance
Canadians who suffer cardiac arrest outside of a hospital are three to four times more likely to survive if they receive cardiopulmonary resuscitation (CPR). According to the Canadian Association of Emergency Physicians, such assistance is provided in only about one-quarter of cases. In a position statement on "bystander" CPR to be published in the Canadian Journal of Emergency Medicine, CAEP says it is not acceptable that vast numbers of witnessed cardiac arrest victims do not receive bystander CPR. More than 20,000 people suffer out-of-hospital cardiac arrests in Canada each year, with 85 per cent of cases occurring in residential dwellings. Currently, less than 10 per cent of these people survive. Every Canadian should be trained in CPR and all Canadians should respond and provide chest compressions, with or without mouth-to-mouth ventilation, whether they are trained or not, CAEP says
EP lab to eliminate need for out-of-province travel (Saskatoon)
"My breath was so short, I lost control of my breathing. I was admitted to RUH, put on oxygen and an aortic heart pump," he says. "I survived, but was in the hospital for a week and a half before taking the air ambulance to Calgary for the other implant."
Heart health is important to everyone, however to those with heart conditions like York, it's the difference between life and death. For that reason, Royal University Hospital, already a leader in cardiac care, is moving forward with construction on its much anticipated cardiac electrophysiology (EP) lab. The lab will allow patients in Saskatchewan to receive procedures here instead of leaving the province.
Two EP cardiologists, Dr. Carlo Stuglin and Dr. Kelly Coverett, currently conduct EP procedures out of the cardiac catheterization lab at RUH one day a week. That's possible through equipment purchased in 2009 by the Royal University Hospital Foundation and Saskatoon Health Region. As of April 21 they began implanting ICDs in the operating room. "I can't tell you how grateful I am for the program Dr. Coverett has developed," said York at the RUH Foundation Donor Grand Rounds on May 17, 2011. "My son and his wife are both med-school grads and they both said that if I hadn't been at RUH and had access to the kind of care they provide, I would have died. No question."
The two-phase construction of the EP lab begins this month (June 2011). The full lab is expected to be operational in spring 2012. The EP lab will share the same space at RUH as the cardiac catheterization lab. With support from the RUH Foundation, it is expected that the new EP lab will be as good as or better than any other lab in North America. With a dedicated lab, a wait list of 18 months will be shortened and patients can have these surgeries in Saskatoon.
"Our campaign for 2011-2012 will focus on raising $5.5 million to build a dedicated EP lab," says Arla Gustafson, CEO of the RUH Foundation. "Patients like Terry and their families will be able to stay in province for surgery and procedures, which is always a better option for them and their families." The Kinsmen Telemiracle Foundation has already donated $1.5 million for the equipment that will be installed in the EP lab. (Reprinted from SHR, Region Reporter)

Mayo Clinic finds estrogen may prevent younger menopausal women from strokes
Estrogen may prevent strokes in premature or early menopausal women, Mayo Clinic researchers say. Their findings challenge the conventional wisdom that estrogen is a risk factor for stroke at all ages. The study was published in the journal Menopause. Researchers combined the results from a recent Mayo Clinic study with six other studies from across the world and found that estrogen is protective for stroke before age 50. That is roughly the average age when women go through menopause. "We were very surprised because these results were unexpected," says study author Walter Rocca, M.D., an epidemiologist and neurologist at Mayo Clinic. "The old idea that estrogen is always a problem in the brain has to be corrected." Estrogen can be a problem in older women, he explains, but in younger women, estrogen may be important to protect the brain from strokes. The study has implications for women who experience premature (before age 40) or early menopause (before age 45) from natural causes or from ovary removal. Women in these groups should consider taking estrogen up to approximately age 50 to prevent stroke, Dr. Rocca says. Ischemic stroke occurs as a result of an obstruction within a blood vessel supplying blood to the brain. According to the American Stroke Association, these types of strokes account for 87 percent of all stroke cases
Einstein College of Medicine given $6.7 million to study congenital heart defect genetics
The Eunice Kennedy Shriver National Institute of Child Health & Human Development, part of the National Institutes of Health, has awarded researchers at Albert Einstein College of Medicine of Yeshiva University and collaborators at the Children's Hospital of Philadelphia a five-year, $6.7 million grant to study the genetics of both rare and common congenital heart abnormalities known as conotruncal defects. CTDs account for more than one-third of all heart defects. They can involve a faulty connection between the heart's chambers or an abnormality affecting a major blood vessel leaving the heart. Some of the more common CTDs include ventricular septal defects and tetralogy of Fallot
Increasing cardiovascular disease in China: urgent need for prevention
At over 40%, the mortality rate due to cardiovascular disease in China is amongst the highest in the world and has been rightly described as an epidemic. Its population faces a catalogue of CVD risk factor statistics that expose high levels of obesity, diabetes, cholesterol and blood pressure, and a smoking habit within males that is proving stubborn to address. To support efforts to implement a series of treatment and prevention strategies that can help reverse these worrying trends, the European Society of Cardiology announces that it will deliver an educational programme at the 22nd Great Wall International Congress of Cardiology. The ESC has been invited for the second time by its affiliate, the Chinese Society of Cardiology, to co-host a special symposium during the congress, which runs from 15 October in Beijing
Researchers make older beta cells act young again
As a person ages, the ability of their beta cells to divide and make new beta cells declines. By the time children reach the age of 10 to 12 years, the ability of their insulin-producing cells to replicate greatly diminishes. If these cells, called beta cells, are destroyed - as they are in type 1 diabetes - treatment with the hormone insulin becomes essential to regulate blood glucose levels and get energy from food. Now, longtime JDRF-funded researchers at Stanford University have identified a pathway responsible for this age-related decline, and have shown that they can tweak it to get older beta cells to act young again - and start dividing. The work, to appear in the October 12 issue of Nature, provides the most complete picture to date of the molecular and biochemical mechanisms that bring beta cell regeneration to a near halt as beta cells age. These findings may help pave a path for developing strategies to restore beta cell number to treat both type 1 and type 2 diabetes
High cholesterol might be linked to Alzheimer's Disease
New research suggests that high cholesterol levels could boost the risk of Alzheimer's disease by creating more brain-clogging bits known as plaque. The finding doesn't directly prove that high cholesterol causes Alzheimer's disease or that lowering it would reduce the risk. Also, researchers didn't find any link between high cholesterol and tangles, which also clog the brain in those with Alzheimer's. Still, the findings add to previous research that has linked insulin resistance to Alzheimer's disease, said study author Dr. Kensuke Sasaki. Better control of both cholesterol levels and insulin resistance, both risk factors for heart disease, "might contribute to a strategy for the prevention of Alzheimer's disease," said Sasaki, an assistant professor of neuropathology at Kyushu University in Japan

Defibrillators in Scottish shops
A scheme which will see life-saving devices installed in 40 stores in Scotland has been hailed by Health Secretary Nicola Sturgeon. The Semichem shop in Kirkcaldy is the first to have its staff trained to use the automated defibrillators which can help save the lives of heart attack victims. As part of the programme the devices, which give the heart an electric shock, are being installed in Scotmid, Semichem and Fragrance House shops. The Scottish Ambulance Service is helping Scotmid to purchase and install the in-store defibrillators, training staff to ensure they can use them quickly if needed. The ambulance service also worked closely with the company to identify those stores where the defibrillators are likely to save the most lives
