Dosage of HIV drug may be ineffective for half of African-Americans

Many African-Americans may not be getting effective doses of the HIV drug maraviroc, a new study from Johns Hopkins suggests. Continue reading

Finding keys to glioblastoma therapeutic resistance

Finding keys to glioblastoma therapeutic resistance

Researchers at the University of California, San Diego School of Medicine have found one of the keys to why certain glioblastomas — the primary form of a deadly brain cancer — are resistant to drug therapy. The answer lies not in the DNA sequence of the tumor, but in its epigenetic signature Continue reading

Nurse anesthetist care not equal to physician anesthesiologist-led care, comprehensive evidence-based review finds

Nurse anesthetist care not equal to physician anesthesiologist-led care, comprehensive evidence-based review finds

A recent literature review by the Cochrane Collaboration found no scientific evidence that care provided by a nurse anesthetist is as safe and effective as patient-centered, physician-led anesthesia care, prompting the American Society of Anesthesiologists (ASA®) to call for further examination to measure patient safety and anesthesia care delivery. The review, “Physician anaesthetists versus non-physician providers of anaesthesia for surgical patients,” attempted to assess the safety and effectiveness of physician-led versus nurse-led anesthesia care delivery. While the authors stated intent that they “hoped that this review may lead to an increase in confidence in the skills of NPAs nurse anesthetists within the anaesthetic community,” the comprehensive analysis could not support this premise.

Are you as old as what you eat? Researchers learn how to rejuvenate aging immune cells

Are you as old as what you eat? Researchers learn how to rejuvenate aging immune cells

Researchers from UCL (University College London) have demonstrated how an interplay between nutrition, metabolism and immunity is involved in the process of aging. The two new studies, supported by the Biotechnology and Biological Sciences Research Council (BBSRC), could help to enhance our immunity to disease through dietary intervention and help make existing immune system therapies more effective Continue reading

Cutting emissions pays for itself, study concludes

Cutting emissions pays for itself, study concludes

Lower rates of asthma and other health problems are frequently cited as benefits of policies aimed at cutting carbon emissions from sources like power plants and vehicles, because these policies also lead to reductions in other harmful types of air pollution. But just how large are the health benefits of cleaner air in comparison to the costs of reducing carbon emissions? MIT researchers looked at three policies achieving the same reductions in the U.S., and found that the savings on health care spending and other costs related to illness can be big — in some cases, more than 10 times the cost of policy implementation Continue reading

Mimicking natural evolution with ‘promiscuous reactions’ to improve the diversity of drugs

Mimicking natural evolution with ‘promiscuous reactions’ to improve the diversity of drugs

The researchers, who report their findings online in the journal Nature Chemistry , took their inspiration from evolution in nature. The research may uncover new pharmaceutical drugs that traditional methods would never have found. “Nature produces some amazing structures with really interesting biological activity, but the plant or animal did not design them.

Simply complex: The origin of our body axes

Simply complex: The origin of our body axes

The fresh-water polyp Hydra, a member of the over 600-million-year-old phylum Cnidaria, is famous for its virtually unlimited regenerative capability and hence a perfect model for molecular stem cell and regeneration research. This polyp, with its simple structure and radial symmetry, can help us understand how our body axes came to evolve Continue reading

Cognitive-behavioral coping skills training has positive effects on rheumatoid arthritis

Cognitive-behavioral coping skills training has positive effects on rheumatoid arthritis

Rheumatoid arthritis (RA), a complex autoimmune disease that affects 1 to 2 percent of adults, requires patients to not only cope with pain, disability and joint disfigurements, but also other stressors such as disrupted work, family life and marital functioning. Continue reading

Women with severe, chronic health issues are screened for breast cancer less often

Women with severe, chronic health issues are screened for breast cancer less often

Women with severe disabilities and multiple chronic conditions are screened for breast cancer less often than women with no disabilities or no chronic conditions, a new study has found. They are also screened less often than women with moderate disabilities or women with only one chronic condition, according to Dr. Sara Guilcher, an affiliate scientist with the Li Ka Shing Knowledge Institute of St Continue reading

More common procedures for painful facial tics carry high costs

More common procedures for painful facial tics carry high costs

For patients who need surgery for facial pain caused by trigeminal neuralgia, the most cost-effective procedure is the least often used, reports a study in the September issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. Continue reading
