Naproxen plus acid blocking drug shows promise in preventing bladder cancer

A new study suggests there may be ways to reduce these dangerous side effects. Collaborators from the University of Michigan, the National Cancer Institute and the University of Alabama looked at naproxen, which is known to have a lower cardiovascular risk than other NSAIDs. Naproxen, like most NSAIDs and aspirin, does increase the risk for gastric ulcers or bleeding…

Potential new breathalyzer for lung cancer screening

Their work, described in a paper published this week in the journal Review of Scientific Instruments, from AIP Publishing, demonstrates the potential of the device to be used as a breathalyzer for early lung cancer detection — possibly a safe and effective method of detecting cancer early that may save lives. According to the researchers, the laboratory results are promising, but the device would still need to prove effective in clinical trials before its widespread adoption as a diagnostic tool. “Our results show that the device can discriminate different kinds and concentrations of cancer related volatile organic compounds with a nearly100 percent accurate rate,” said Jin-can Lei, the primary researcher and a postdoc from the College of Optoelectronic Engineering, Chongqing University. “This would also be a rapid method in that the entire detection process in our experiment only takes about 20 minutes.” Based on a small, circular plate called fluorescent cross-responsive sensor array, a specially-designed rotary gas chamber and a data collection and processing system, the device can detect lung cancer related gases at very low concentration, or below 50 parts per billion (ppb), showing a potential to identify lung cancer at the early stage. …

Young Puerto Rican women and their mothers know little about HPV, cervical cancer

According to the study published in Preventing Chronic Disease, a publication of the Centers for Disease Control and Prevention, HPV vaccination rates are low among Puerto Rican women. Fifty one percent of Puerto Rican girls aged 11 to 18 have started the 3-step vaccination process and only 21 percent have completed the series. “Our study is the first to provide insight into common psychosocial barriers affecting HPV vaccination in Puerto Rico,” said Mar�a E…

‘Landmark’ results for curing hepatitis C in liver transplant patients

The investigational three-drug regimen, which produced hepatitis C cure rates of 97 percent, is an oral interferon-free therapy. Previously, the typical treatment for hepatitis C after a liver transplant was an interferon-based therapy, usually given for 48 weeks. It had a much lower response rate, had a risk of organ rejection and was poorly tolerated because of the immunosuppressants required to prevent rejection. The new oral regimen — ABT-450, ombitasvir and dasabuvir (with or without ribavirin) — produces significantly fewer side effects and is prescribed for 24 weeks…

Genetic variant protects some Latina women from breast cancer

The variant, a difference in just one of the three billion “letters” in the human genome known as a single-nucleotide polymorphism (SNP), originates from indigenous Americans and confers significant protection from breast cancer, particularly the more aggressive estrogen receptor-negative forms of the disease, which generally have a worse prognosis. “The effect is quite significant,” said Elad Ziv, MD, professor of medicine and senior author of the study. “If you have one copy of this variant, which is the case for approximately 20% (the range being 10 to 25 percent) of U.S. …

Elevated cholesterol, triglycerides may increase risk for prostate cancer recurrence

“While laboratory studies support an important role for cholesterol in prostate cancer, population-based evidence linking cholesterol and prostate cancer is mixed,” said Emma Allott, PhD, postdoctoral associate at Duke University School of Medicine in Durham, North Carolina. “Understanding associations between obesity, cholesterol, and prostate cancer is important given that cholesterol levels are readily modifiable with diet and/or statin use, and could therefore have important, practical implications for prostate cancer prevention and treatment. “Our findings suggest that normalization, or even partial normalization, of serum lipid levels among men with dyslipidemia [abnormal lipid profile] may reduce the risk of prostate cancer recurrence,” said Allott. …

Pneumococcal vaccine reduces antibiotic-resistant infections in children by 62 percent

The 13-valent pneumococcal conjugate vaccine (PCV13), first available in 2010 (replacing 7-valent pneumococcal conjugate vaccine, PCV7), reduced the incidence of antibiotic-resistant invasive pneumococcal disease by 62 percent from 2009 to 2013 among children under five years old. The study is the first report of the effectiveness of PCV13 to combat antibiotic-resistant infections, a vaccination recommended for children under five years old. …

Hormone loss could be involved in colon cancer

The researchers at Thomas Jefferson University examined colon cancer samples from 281 patients and compared those tissues to nearby colon tissue that wasn’t cancerous. They found that guanylin production — measured by number of messenger RNAs for guanylin contained in each cell — decreased 100 to 1,000 times in more than 85 percent of colon cancers tested. They verified their results by also staining for the guanylin hormone production in slices of the tissue samples. …
