| Better predictor of prostate cancer survival proposed by research Posted: 21 Mar 2014 01:48 PM PDT Measuring circulating tumor cells -- the cells that spread cancer through the body -- may be a better predictor of patient survival than the prostate-specific antigen, new research indicates.  |
| Characteristics of lung cancers arising in genetic mutation carriers Posted: 21 Mar 2014 01:48 PM PDT Two studies are providing new insight into germline epidermal growth factor receptor T790M mutation in familial non-small cell lung cancer. The findings suggest the need for tailored approaches for early detection and treatment, as well as for genetic testing to identify carriers. "These studies now solidify the fact that routine clinical management of lung cancer now has to include the awareness of this inherited cancer syndrome," said one expert.  |
| Salivary biomarkers of gingivitis: Information important for personalized decision-making Posted: 21 Mar 2014 08:22 AM PDT Salivary biomarkers have been studied to help determine the presence, risk, and progression of periodontal disease. However, clinical translation of salivary biomarkers from bench to chairside requires studies that identify biomarkers associated with the continuum of phases between health and periodontal disease. Thus, the objective of this study was to identify salivary biomarkers associated with gingivitis.  |
| New regulatory mechanisms of cell migration found in drosphilia fly study Posted: 21 Mar 2014 07:17 AM PDT New insight into the genetic regulation of cell migration has been discovered by researchers. Cell migration is highly coordinated and occurs in processes such as embryonic development, wound healing, the formation of new blood vessels, and tumour cell invasion. For the successful control of cell movement, this process has to be determined and maintained with great precision. In this study, the scientists used tracheal cells of the fruit fly Drosophila melanogaster to unravel the signalling mechanism involved in the regulation of cell movements.  |
| Posted: 21 Mar 2014 06:52 AM PDT Chronically ill adults who reported food insecurity in their household (not having consistent access to food due to lack of financial stability) were significantly more likely to report cost-related medication underuse, according to a new study. The term cost-related medication underuse refers to taking less medication than prescribed or not taking it at all due to financial concerns.  |
| Posted: 21 Mar 2014 06:47 AM PDT To aid in the function and appearance of battlefield scars, military dermatologists began experimenting with ablative fractional laser surgery – known to improve the appearance of acne scars. Results over the last seven years have been impressive, and dermatologists now are treating civilians injured from car accidents, fires and job and household accidents with this laser therapy to enhance scar and wound healing.  |
| Posted: 21 Mar 2014 06:47 AM PDT As more people look for ways to turn back the clock or improve their appearance, dermatologists are pioneering many of the newest aesthetic laser technologies – from tattoo removal to erasing fine lines and wrinkles to reducing fat or cellulite. Before considering any cosmetic procedure, dermatologists recommend that consumers do their homework to better understand the best technologies available for their specific needs.  |
| Genetic clue to irritable bowel syndrome found Posted: 20 Mar 2014 02:31 PM PDT Is irritable bowel syndrome (IBS) caused by genetics, diet, past trauma, anxiety? All are thought to play a role, but now, for the first time, researchers have reported a defined genetic defect that causes a subset of IBS. Researchers estimate that approximately 15 to 20 percent of the Western world has IBS. It is a common disorder that affects the large intestine. Most patients with the disorder commonly experience symptoms of cramping, abdominal pain, bloating gas, diarrhea and constipation.  |
| Dentistry: Resin infiltration effects in a caries-active environment -- two-year results Posted: 20 Mar 2014 08:19 AM PDT Researchers found in a pilot study that infiltration successfully stabilized early non-cavitated lesions in a small population with high caries-activity. Continuing follow-up may further confirm its efficacy. This pilot study identified important promising trends between the plaque and salivary metabolomes from caries-active and caries-free children, despite a relatively low number of subjects.  |
| Tooth loss linked to depression, anxiety Posted: 20 Mar 2014 08:19 AM PDT Tooth loss from caries and periodontal disease is an outcome from complex, chronic conditions. Several biopsychosocial factors are involved, including accessing care. Individuals reporting dental anxiety may avoid dental care; and individuals with depression may be negligent in self-care. In this study, researchers examined a potential association of tooth loss with depression and anxiety.  |
| School hearing tests do not detect noise exposure hearing loss Posted: 20 Mar 2014 07:14 AM PDT School hearing tests cannot effectively detect adolescent high-frequency hearing loss, which is typically caused by loud noise exposure, according to researchers. School screenings primarily focus on low-frequency hearing loss. This is logical for young children, who are more likely to develop low-frequency hearing loss due to fluid in the ear after a bad cold or an ear infection. Adolescents, however, are more susceptible to high-frequency hearing loss, usually brought on by exposure to loud noises, but the same tests are used on adolescents and young children.  |
