“Snus causes cancer” – health institute

Source: thelocal.se Author: Staff Swedish snus causes cancer and increases the risk of death from heart disease, according to the National Institute of Public Health. The warning, which will concern many Swedes who have turned to snus as a healthier nicotine alternative to smoking, is based on the institute's analysis of epidemiological and experimental studies carried out by the Karolinska Institutein recent years. Certain studies indicate that snus can also increase the risk of high blood pressure and diabetes, and that children could be born prematurely if mothers use snus during pregnancy. However, the Institute of Public Health said in its report that there is not yet enough evidence to be certain of the effect on births. The institute said that its analysis showed that using snus increased the risk of cancer of the pancreas and of the mouth. But there are no research results suggesting that it causes other forms of cancer. And while there is no evidence to suggest that using snus actually increases the risk of developing heart disease, it is clear that it does increase the risk of death for a person affected, for example, by a heart attack. The details of how much snus is dangerous are not yet known, said Göran Pershagen, professor at the Institute of Environmental Medicine at Karolinska. "There's not enough evidence to say how much the risk increases. But it is clear that snus is not unhazardous - pancreatic cancer is a relatively common form of cancer with a very poor survival rate," he [...]

Radiation exposure may increase risk of stroke and heart disease

Source: www.onmedica.com Author: OnMedica Staff Exposure to moderate levels of radiation may increase the rates of heart disease and stroke, according to new research. Several studies have shown that high doses of radiation to the heart or head and neck from radiotherapy cause an excess of deaths from heart disease or stroke in later years. But it is uncertain whether radiation exposures at relatively low dose levels (under 1 Gy) also increase the risk. To investigate this further, Dr Yukiko Shimizu and colleagues from the Radiation Effects Research Foundation in Japan examined the risk of heart disease and stroke in 86,611 atomic bomb survivors from Hiroshima and Nagasaki who have been followed up for 53 years, from 1950 to 2003, as part of the Japanese atomic bomb survivor Life Span Study. Each member of the group had received an estimated radiation dose from 0-4 Gy (86% received less than 0.2 Gy) at the time of the bomb. Other risk factors for circulatory disease that could have affected the results, such as smoking, alcohol intake, education, occupation, obesity and diabetes were also taken into account. The researchers found an elevated risk of both stroke and heart disease at doses above 0.5 Gy, but the degree of risk at lower doses was unclear. Together, this represents about 210 excess deaths from circulatory disease associated with radiation exposure – about a third as many as the total excess number of cancer deaths (about 625) among atomic bomb survivors in the Life Span Study.

Head and neck cancer surgery patients at major risk of developing myocardial ischaemia

Source: www.docguide.com/news Author: Lexa W. Lee Of patients with head and neck cancer who have undergone surgery, 15% will develop postoperative myocardial ischemia, according to a study presented here October 19 at the 2009 Annual Meeting of the American Society of Anesthesologists (ASA). In addition, ischaemia is a strong predictor of 60-day mortality following surgery, according to presenter Lesley Rao, MD, Washington University, St. Louis, Missouri. For the study, researchers performed a retrospective cohort study of 378 patients who underwent major head and neck cancer surgery. Potential risk factors for postoperative myocardial ischemia, such as heart disease and smoking history, were recorded. Troponin levels were serially measured up to the fifth day after surgery. Peak postoperative troponin I (TnI) concentration was the main outcome variable; a level over 0.1 ng/mL was considered abnormally high. Of the 378 patients, 57 patients (15%) developed an elevated TnI; 90% of which occurred within 24 hours after surgery. A history of renal insufficiency, coronary artery disease, peripheral vascular disease, hypertension, and combined chemotherapy and radiation were associated with elevated postoperative TnI. This group had a significantly longer length of stay in the hospital compared with those with lower TnI levels (8.5 vs 10.1 days; P = .014), ICU stay (3 vs 4.5 days; P = .001), and an 8-fold higher risk of death at 60 days following surgery (odds ratio [OR] = 7.62; 95% confidence interval [CI], 1.98-29.31). At 1 year, patients with an abnormally high postoperative TnI were twice as likely to die [...]

Worldwide study shows MI risk increases with all forms of tobacco use

Source: HeartWire Author: Steve Stiles London, UK - Tobacco use significantly ups the risk of nonfatal MI independently of its varied methods around the world and whether exposure is direct or through second-hand smoke, according to INTERHEART, a large, broadly international case-control study [1]. The findings sharpen and add a global perspective to the massive epidemiologic evidence implicating smoking and other tobacco uses as causes of heart disease. The analysis, which appears in the August 19, 2006 issue of the Lancet, suggests that current cigarette smoking confers nearly triple the adjusted MI risk faced by persons who have never smoked and that the hazards can't be escaped by resorting to other forms of tobacco use. The study looked at the effects of not only smokeless tobacco but also less common modes of smoking, including some that are primarily limited to specific geographic regions such as South and Central Asia. "Our findings show that tobacco in any form is harmful," write the authors, Dr Koon K Teo (McMaster University-Hamilton Health Sciences, Hamilton, ON) and associates. Other noteworthy observations include a significant dose-response relationship between the number of cigarettes consumed daily and the likelihood of MI, even at only a few cigarettes per day. Commenting on the study for heartwire, Dr Ira S Ockene (University of Massachusetts Medical School, Worcester) said that it replicates much earlier work but "adds so much more," including a global perspective not only geographically but in terms of spanning virtually all forms of tobacco exposure. Its data on the risks of chewing [...]

Your mouth can tell a lot about your health

Source: www.sfgate.com Author: Michael Birnbaum, Washington Post Your mouth can tell you a lot about your overall health. Troubled teeth and gums aren't always just a dental problem. Sometimes they indicate deeper issues, and dentists are increasingly picking up the clues. "We look around the mouth and we look for color changes. We're looking for certain smells. Spots around the gums," said Washington dentist Joseph Kravitz. The relation of oral health to the rest of the body has received increased attention in recent years, spurred by such experts as Richard Carmona, who as surgeon general urged policymakers in 2003 to "increase the understanding of how the signs and symptoms of oral infections can indicate general health status and act as a marker for other diseases." The publicity reminded a lot of dentists that their jobs weren't just about root canals and fillings, Kravitz said. Here are some conditions the possible clues dentists may be able to identify: Heart disease. Gums that have turned a "bright beefy red" or purple. Type 2 diabetes. Gums that bleed at the slightest touch although there is no plaque evident. Kidney disease. A sweet ammonia smell on a person's breath. Acid reflux. Teeth that look worn and pitted, as if they'd been "dipped in battery acid." Oral cancer. Gum tissues with white spots that last two weeks or more. Leukemia. Fiery-red swollen gums that just won't heal. Osteoporosis. Black spots on tooth X-rays that indicate air pockets and dead bone. Stress. Gums that have pulled [...]

Chewing tobacco use surges among boys

Source: Msnbc.msn.com Author: Staff WASHINGTON - Use of snuff and chewing tobacco by U.S. adolescent boys, particularly in rural areas, has surged this decade, a federal agency said in a report on Thursday that raised concern among tobacco control advocates. The use of such smokeless tobacco products increases the risk of oral cancer as well as heart disease and stroke. It leads to nicotine addiction just like cigarette smoking. The report by the U.S. Substance Abuse and Mental Health Services Administration showed a 30 percent increase in the rate of smokeless tobacco use among boys aged 12 to 17 from 2002 to 2007. Use by adults remained stable. In 2007, the report estimated that 566,000 boys in that age group had used chewing tobacco or snuff. "This trend toward more smokeless tobacco use by kids is of great concern," Danny McGoldrick, vice president for research at the Campaign for Tobacco-Free Kids advocacy group, said in a telephone interview. "This is an industry that has a history of targeting kids because they know that's when everybody starts," he added. Among adolescent boys, the rate of use of smokeless tobacco rose from 3.4 percent in 2002 to 4.4 percent in 2007, according to the report. McGoldrick said the increase occurred as smokeless tobacco companies greatly increased their spending on marketing and introduced a new range of products. The findings reiterated the need for the U.S. Food and Drug Administration to have the power to regulate tobacco products, as legislation being considered by [...]

Study says smoking may hurt women more than men

Source: apnews.myway.com Author: Maria Cheng Women who smoke may develop heart disease at almost the same age as male smokers, wiping out the natural difference between the sexes, doctors said Tuesday. In research presented to the European Society of Cardiology, Norwegian researchers said that women who smoke have heart attacks nearly 14 years earlier than women who don't smoke. For men, the figure is about six years. "This is not a minor difference," said Dr. Silvia Priori, a cardiologist at the Scientific Institute in Pavia, Italy. "Women need to realize they are losing much more than men when they smoke," she said. Priori was not connected to the research. Dr. Morten Grundtvig and colleagues from the Innlandet Hospital Trust in Lillehammer, Norway, looked at data from 1,784 patients admitted for a first heart attack at a hospital in Lillehammer. They found that the men on average had their first heart attack at age 72 if they didn't smoke, and at 64 if they did. The women had their first heart attack at age 81 if they didn't smoke, and at age 66 if they did. After adjusting for other heart risk factors like blood pressure, cholesterol and diabetes, researchers found that the difference for women was 14 years and for men was six years. Previous studies looking at whether there is a difference between the genders in the risks of smoking have been inconclusive. Doctors have long suspected that female hormones protect women against heart disease. Estrogen is thought to [...]
