FDA issues graphic cigarette labels

Source: apnews.myway.com Author: Michael Felberbaum In the most significant change to U.S. cigarette packs in 25 years, the Food and Drug Administration on Tuesday released nine new warning labels that depict in graphic detail the negative health effects of tobacco use. Among the images to appear on cigarette packs are rotting and diseased teeth and gums and a man with a tracheotomy smoking. Also included among the labels are: the corpse of a smoker, diseased lungs, and a mother holding her baby with smoke swirling around them. They include phrases like "Smoking can kill you" and "Cigarettes cause cancer" and feature graphic images to convey the dangers of tobacco, which is responsible for about 443,000 deaths in the U.S. a year. Each label includes a national quit smoking hotline number. The labels will take up the top half of a pack of cigarette packs. Warning labels also must appear in advertisements and constitute 20 percent of an ad. Cigarette makers have until the fall of 2012 to comply. Mandates to introduce new graphic warning labels were part of a law passed in 2009 that, for the first time, gave the federal government authority to regulate tobacco, including setting guidelines for marketing and labeling, banning certain products and limiting nicotine. The announcement follows reviews of scientific literature, public comments and results from an FDA-contracted study of 36 labels proposed last November. In recent years, more than 30 countries or jurisdictions have introduced labels similar to those being introduced by the FDA. [...]

Early effect of the HPV vaccination programme on cervical abnormalities in Victoria, Australia: an ecological study

Source: The Lancet Summary: Background Australia introduced a human papillomavirus (HPV) vaccination programme with the quadrivalent HPV vaccine for all women aged 12—26 years between 2007 and 2009. We analysed trends in cervical abnormalities in women in Victoria, Australia, before and after introduction of the vaccination program. Methods With data from the Victorian Cervical Cytology Registry between 2003 and 2009, we compared the incidence of histopathologically defined high-grade cervical abnormalities (HGAs, lesions coded as cervical intraepithelial neoplasia of grade 2 or worse or adenocarcinoma in situ; primary outcome) and low-grade cytological abnormalities (LGAs) in five age groups before (Jan 1, 2003, to March 31, 2007) and after (April 1, 2007, to Dec 31, 2009) the vaccination programme began. Binary comparisons between the two periods were done with Fisher's exact test. Poisson piecewise regression analysis was used to compare incident rate trends. Findings After the introduction of the vaccination programme, we recorded a decrease in the incidence of HGAs by 0·38% (95% CI 0·61—0·16) in girls younger than 18 years. This decrease was progressive and significantly different to the linear trend in incidence before introduction of the vaccination (incident rate ratio 1·14, 1·00—1·30, p=0·05). No similar temporal decline was recorded for LGAs or in older age groups. Interpretation This is the first report of a decrease in incidence of HGAs within 3 years after the implementation of a population-wide HPV vaccination programme. Linkage between vaccination and screening registers is needed to confirm that this ecological observation is attributable to vaccination and [...]

For the first time in nearly four decades, smokeless tobacco has no hand in sponsoring the College National Finals Rodeo

Source: Billings Gazette CASPER, Wyo. — The once steadfast coupling of chewing tobacco and the collegiate cowboy extravaganza is no more. There are no Copenhagen banners, there are no Skoal flags. There are no free samples. For the first time in nearly four decades, smokeless tobacco has no hand in sponsoring the College National Finals Rodeo. “It’s a tremendous and tragic loss to college rodeo,” National Intercollegiate Rodeo Association Commissioner Roger Walters said during the weeklong 2011 CNFR, which ended Saturday night at the Casper Events Center. “Who lost? Our students.” For 37 years, U.S. Smokeless Tobacco gave hundreds of thousands of dollars in the form of scholarships to college rodeo. While the presence of the company’s banners and flags at the CNFR ceased in 2009, the company — acquired by Altria that same year — continued giving scholarship money through last year. Walters said the company, in a time of economic hardship, gave roughly $250,000 in scholarships each year to college rodeo performers. The sponsorship pullout by the company, he said, constituted an 80 to 85 percent loss in money available for the performers. “I understand the reasons (for their departure), but in the long run, it hurts our students,” he said. “And that’s what this rodeo is for, first and foremost.” Health officials, however, applauded the move. “It is never a good idea to promote a product that is a deadly killer,” said Niki Mueller, the program director of Wyoming Through With Chew. “Rodeo is a family event, [...]

Researchers find protein that could help predict head and neck cancer

Source: www.medindia.net Author: Sheela Philomena Researchers have identified a protein that could pave way to predict the spread of head and neck cancer nasopharyngeal carcinoma (NPC). The study by Van Andel Research Institute (VARI) researchers found the protein could also serve as part of a treatment strategy to stop the spread of the disease. Though uncommon in the United States, NPC is one of the most common malignant tumours in southern China and Southeast Asia with incidence rates nearly 25 times that of most of the rest of the world. VARI researchers worked with scientists in Singapore, China, and the United States on the study. "This study does not just report another molecular marker for metastasis of nasopharyngeal cancer, these investigators have revealed an important process related to this molecule," Wei Zhang, Ph.D., Professor at M.D. Anderson Cancer Center, explained. "Characterization of this process will open diverse opportunities for effective inhibition of this novel target for cancer metastasis," Zhang said. NPC is the most common cancer originating in the nasopharynx area of the throat and has the highest metastasis rate among head and neck cancers. By the time patients are diagnosed, the disease has usually spread to lymph nodes or distant organs such as the liver. Working together with physicians and scientists at Sun Yat-sen University Cancer Center in China, VARI researchers found that the protein serglycin is a marker of metastasis for NPC. Higher levels of serglycin correlated with an unfavourable prognosis and the increased likelihood that cancer would [...]

Matthew Algeo’s ‘The President is a Sick Man’ vindicates an old story, and its reporter

Source: www.cleveland.com/books Author: teve Weinberg Stephen Grover Cleveland, born in 1837, would become one of the most unusual U.S. presidents, in multiple ways. Living in the east, he planned to make his way to the boomtown of Cleveland, in 1854, seeking riches. His prospects looked good, given the influence of his distant relative, Moses Cleaveland, often credited with founding the city. The young man never made it past Buffalo, N.Y., however, where an uncle made him an employment offer. The rest of his life, Grover Cleveland (he dropped Stephen in favor of his middle name) would be bound up in New York state politics, except when he spent two nonconsecutive terms in the White House, 1885-1889 and 1893-1897. Matthew Algeo, a historian and radio journalist, focuses on a dramatic, little-known event in his new book, "The President Is a Sick Man." Algeo, a strong writer, nevertheless saddles his work with a ponderous subtitle "Wherein the Supposedly Virtuous Grover Cleveland Survives a Secret Surgery at Sea and Vilifies the Courageous Newspaperman Who Dared Expose the Truth." Suffering from mouth cancer in 1893, Cleveland disappeared to undergo surgery on the yacht of a friend. The president, his doctors and political advisers feared that news might exacerbate a financial recession and trigger panic. Cleveland's popular wife, Frances, young enough to be his daughter, lied to journalists about the president's whereabouts. Cleveland's press aide lied, too. Reporters accepted the falsehoods, misleading the citizenry into believing the nation's leader vanished for five days to undergo [...]

Finally, a selfish reason to get boys vaccinated for HPV

Source: www.slate.com Author: Kent Sepkowitz A vaccine that prevents cancer is the dream of just about every patient, doctor, and public health official. Therefore, hopes were quite high five years ago, when the U.S. Food and Drug Administration approved a vaccine to prevent human papillomavirus, or HPV, a sexually transmitted virus that causes almost all cases of cervical cancer. But despite its clear efficacy, the vaccine has been something of a dud. According to a 2008 survey, only 34 percent of the target crowd, girls aged 13 to 17 years, had received it. The reasons for the slow uptake relate to generic vaccine issues (cost, pain, distrust) as well as a particular discomfort with this one, dubbed the "sex vaccine" by many conservatives, who object to it on the grounds that it somehow promotes licentious behavior (as if it were possible to make teenagers any hornier). However, a new study presented at last week's annual meeting of the American Society of Clinical Oncologists makes the vaccine look even more valuable. Though preliminary and still unpublished, these findings have the potential to finally shift the perception that HPV is a woman's problem and convince parents to get their boys vaccinated against the virus, too. The researchers make the most compelling case to date that HPV causes yet another malignancy—oropharyngeal cancer, a disease that affects men three times more often than women. (It's a subcategory of "oral" or "head and neck" cancer, which also predominantly affect men.) Their work appears to have [...]

Cancer death rate gap widens based on education

Source: apnews.myway.com Author: Mike Stobbe The gap in cancer death rates between college graduates and those who only went to high school is widening, the American Cancer Society reported Friday. Among men, the least educated died of cancer at rates more than 2 1/2 times that of men with college degrees, the latest data show. In the early 1990s, they died at two times the rate of most-educated men. For women, the numbers aren't as complete but suggest a widening gap also. The data, from 2007, compared people between the ages of 25 and 64. People with college degrees are seeing a significant drop in cancer death rates, while people who have spent less time in school are seeing more modest improvements or sometimes none at all, explained Elizabeth Ward, who oversees research done by the cancer society. The cancer society estimates there will be nearly 1.6 million new cancer cases in the United States this year, and 571,950 deaths. It also notes that overall cancer death rates have been dropping since the early 1990s, but the decline has been greater for some groups more than others. Experts believe that the differences have to do with education, how much people earn and where they live, among other factors. Researchers like to use education as a measuring stick because death certificates include that information. "Just because we're measuring education doesn't mean we think education is the direct reason" for the differences among population groups, Ward said. That said, the cancer death [...]

Glowing Cornell Dots Target Cancer

SOURCE: Journal of Clinical Investigation, June 13, 2011 (Ivanhoe Newswire)-- New medical technology is showing that Cornell dots may be a potential cancer diagnostic tool. The U.S Food and Drug Administration (FDA) has recently approved the first clinical trial in humans using Cornell Dots- brightly glowing nanoparticles that can light up cancer cells in PET-optical imaging. Cornell Dots are silica spheres less than eight nanometers in diameter that enclose several dye molecules. To make the dots stick to tumor cells, organic molecules that bind to tumor surfaces, or even specific locations within the tumors, can be attached to a polyethylene glycol shell. This shell, also referred to as PEG, prevents the body from recognizing the dots as foreign substances. When exposed to near-infrared light, the dots fluoresce much brighter than dye to serve as a beacon identifying the target cells. Researchers say this technology enables visualization during surgical treatment. Cornell Dots were first developed in 2005 by Hooisweng Ow, a coauthor of the paper on this study and once a graduate student working with Ulrich Wiesner, Cornell Professor of Materials Science and Engineering. Ow and other researchers of this technology are currently in the process of forming a new commercial entity in New York City that will help transition this research into commercial products that will benefit cancer patients. Michelle S. Bradbury, M.D, of the Memorial Sloan-Kettering Cancer Center and an assistant professor of radiology at Weill Cornell Medical College, was quoted as saying, "This is the first FDA IND approved [...]

Immunity Drugs Used to Fight Cancer

Source: The Wall Street Journal Scientists are scrambling to develop medications that fight cancer by spurring the body's immune system, a form of treatment that some cancer specialists believe may hold the key to keeping a patient permanently disease-free. The new efforts come in the wake of recent Food and Drug Administration approvals of Dendreon Corp.'s Provenge, an immunotherapy drug used to treat prostate cancer, and Bristol-Myers Squibb Co.'s Yervoy, for melanoma. Other immunotherapy drugs are being developed for a number of other cancers, including lung, brain and kidney cancers. Unlike most traditional therapies that attack a cancer directly, immunotherapy uses the body's own internal defenses to ward off the disease, with the ultimate hope of building up a long-term resistance to the cancer. "If we are ever going to use the word 'cure', the immune system is going to have to come into play," says Stephen Hodi, director of the melanoma center at Dana-Farber Cancer Institute in Boston. One of the ways that cancer survives and ultimately spreads through the body is by exploiting a function in all cells that prevents the immune system from killing them. Researchers have found that cancer cells have multiple methods of avoiding detection and suppressing the immune system's response. "Why would cancer devote so much energy to avoid the immune system if the immune system didn't have the potential to reject the cancer?" says Robert Vonderheide from the Abramson Cancer Center of the University of Pennsylvania. There are big hurdles to advancing the [...]

Palifermin decreases severe oral mucositis after radiotherapy

Source: www.drbicuspid.com Author: Will Boggs, MD Palifermin (Kepivance) helps reduce the rate, severity, and duration of severe oral mucositis in head and neck cancer patients receiving chemoradiotherapy, two new studies show. "Combined data from both studies consistently indicated that palifermin has activities against radiochemotherapy-induced mucositis," said Dr. Quynh-Thu Le, who led one of the studies, in email to Reuters Health. "However, the lack of improvement in some of the secondary end points suggests that the doses and schedules tested were inadequate to overcome the severe mucositis brought on by concurrent radiochemotherapy." The recombinant keratinocyte growth factor palifermin is FDA-approved to treat severe oral mucositis in patients with hematologic malignancies receiving myelotoxic therapy requiring hematopoietic stem cell support. But Dr. Le said that unlike the mucositis related to chemotherapy for bone marrow transplant, mucositis from chemoradiotherapy is more severe and persistent and "may require more drug administered at a higher frequency." Dr. Le, from Stanford University, California, and colleagues tested palifermin, 180 mcg/kg IV once weekly, in 188 patients with locally advanced head and neck cancer receiving definitive chemoradiotherapy. The incidence of severe oral mucositis (grade 3 or 4) was significantly lower with palifermin versus placebo (54% versus 69%; p = 0.041). In addition, the median duration of severe oral mucositis was shorter in the palifermin group (5 versus 26 days), according to a report published online June 13 in the Journal of Clinical Oncology. But mouth and throat soreness (MTS) scores averaged only slightly lower in the palifermin arm, and [...]
