When given alongside radiation therapy for head and neck cancer, acupuncture has shown for the first time to reduce the debilitating side effect of xerostomia, according to new research from The University of Texas MD Anderson Cancer Center and Fudan University Shanghai Cancer Center. The study, published in the journal Cancer, reported findings from the first randomized controlled trial of acupuncture for the prevention of xerostomia. Xerostomia, or severe dry mouth, is characterized by reduced salivary flow, which commonly affects patients receiving radiotherapy for head and neck cancer. Most current treatments are palliative and offer limited benefit, according to Lorenzo Cohen, Ph.D., professor in MD Anderson's Departments of General Oncology and Behavioral Science and director of the Integrative Medicine Program.
Natural health products and medicinal foods should be subject to the same regulations as pharmaceutical drugs to ensure safety and efficacy, states an editorial in CMAJ (Canadian Medical Association Journal). While pharmaceutical drugs are subject to rigorous evaluation and must provide significant evidence of their therapeutic effects and that the benefits outweigh risks, natural health products in Canada are not. Many contain active pharmacological substances that can have potent effects and interactions which should have warnings. "The multibillion-dollar natural health products industry sells the perception that because its products are "natural, " they must also be safe, such that comprehensive testing like that required for pharmaceuticals is not required, " write guest author Dr.
Yoga can provide more effective treatment for chronic lower back pain than more conventional methods, according to the UK's largest ever study into the benefits of yoga. The study, led by the University of York and funded by Arthritis Research UK, found that people offered a specially-designed 12-week yoga programme experienced greater improvements in back function and more confidence in performing everyday tasks than those offered conventional forms of GP care. The research focused on back function - people's ability to undertake activities without being limited by back pain, which was measured using the Roland Morris Disability Questionnaire. Although improvements in back function were more pronounced at three months, researchers found there was still an improvement in people's ability to perform tasks such as walking more quickly, getting dressed without help or standing up for longer periods of time even nine months after the classes had finished.
Yoga classes were linked to better back-related function and diminished symptoms from chronic low back pain in the largest U.S. randomized controlled trial of yoga to date, published by the Archives of Internal Medicine as an "Online First" article on October 24. But so were intensive stretching classes. "We found yoga classes more effective than a self-care book - but no more effective than stretching classes, " said study leader Karen J. Sherman, PhD, MPH, a senior investigator at Group Health Research Institute. Back-related function was better and symptoms were diminished with yoga at 12 weeks; and clinically important benefits, including less use of pain medications, lasted at least six months for both yoga and stretching, with thorough follow-up of more than nine in 10 participants.
Spas that offer massage therapy using fragrant essential oils, called aromatherapy, may have elevated levels of potentially harmful indoor air pollutants such as volatile organic compounds (VOCs) and ultrafine particles, according to an article in Environmental Engineering Science, a peer-reviewed journal published by Mary Ann Liebert, Inc. Fragrant essential oils, derived from plants, may release various VOCs into the air. VOC degradation caused by the reaction of these compounds with ozone present in the air can produce small, ultrafine byproducts called secondary organic aerosols (SOAs), which may cause eye and airway irritation. Taiwanese researchers Der-Jen Hsu (National Kaohsiung First University of Science and Technology), Hsiao-Lin Huang (Chia-Nan University of Pharmacy and Science, Tainan), and Shiann-Cherng Sheu (Chang-Jung Christian University, Tainan) tested both fragrant and Chinese herbal essential oils for SOA formation in a controlled-environment study chamber under different test conditions.
