Johns Hopkins researchers, using a novel birthing simulator designed by biomedical engineering faculty, staff and students at the University, have identified what may be the least forceful way to deliver a baby whose shoulders are stuck in the birth canal.
Shoulder dystocia, in which the baby’s shoulders won’t move past the mother’s bony pelvis during delivery, occurs in about 5 percent of births. Of these, up to a quarter of deliveries may result in an injury to the baby’s brachi
Researchers have shown a correlation between fast food, weight gain, and insulin resistance in what appears to be the first long-term study on this subject. The Coronary Artery Risk Development in Young Adults (CARDIA) study by Mark Pereira, Ph.D., assistant professor in epidemiology, University of Minnesota School of Public Health, and David Ludwig, M.D., Ph.D., director of the Obesity Program at Children’s Hospital Boston, reported that fast food increases the risk of obesity and type 2
FINDINGS: UCLA researchers for the first time showed that advanced heart failure patients with diabetes who are treated with insulin faced a mortality rate four times higher than heart failure patients with diabetes treated with oral medications.
IMPACT: The new study may help raise awareness among physicians and patients of this previously unknown relationship between insulin use and increased mortality in advanced heart failure patients. More research is needed to ex
With more than 28 million Americans suffering from debilitating migraine headaches each year, employers also suffer through missed days from work and reduced productivity. However, Migraine sufferers who had surgical treatment reduced the amount of time missed from work by 73 percent, according to a study published in the January issue of Plastic and Reconstructive Surgery® (PRS), the official medical journal of the American Society of Plastic Surgeons (ASPS). Additionally, surgical treatment
The newest studies on the Cascadia Subduction Zone off the coast of the Pacific Northwest have identified a “clustering” of great earthquakes of the type that would cause a major tsunami, yielding a historical record with two distinct implications – one that’s good, the other not.
According to scientists at Oregon State University, this subduction zone has just experienced a cluster of four massive earthquakes during the past 1600 years, and if historical trends continue, this cl
Undergrad discovered natural form in venomous snails in 1979
The natural form of Prialt – a new drug for severe pain approved this week by the U.S. Food and Drug Administration – was discovered at the University of Utah in 1979 by an incoming freshman studying toxins produced by cone snails.
The student, J. Michael McIntosh, worked in the laboratory of University of Utah biologist Baldomero “Toto” Olivera, the summer before his freshman year as the result of a scholars
A recently developed mouse model of brain tumors common in the genetic disorder neurofibromatosis 1 (NF1) successfully mimics the human condition and provides unique insight into tumor development, diagnosis and treatment, according to researchers at Washington University School of Medicine in St. Louis.
After validating their animal model, the team made two important discoveries: New blood vessels and immune system cells may be essential to the initial formation of tumors and
If a runny nose and congested chest have you thinking of antibiotics, think again.
“For uncomplicated colds, zero are necessary; bronchitis, less than 10 percent are necessary; sore throats, maybe up to 10 to 15 percent of these patients need an antibiotic,” says Dr. Jim Wilde, pediatric emergency medicine and infectious disease physician at the Medical College of Georgia. “Ninety to 95 percent of all infections are viral or low-acuity bacterial infections such as ear infections
Minimally invasive surgery to alleviate the pain and pressure of sinusitis is a safe, effective therapy for geriatric patients who can’t be helped by medication alone, according to new research.
“This tells us that we should not neglect sinus problems in the elderly; that if medicines don’t work, we have a surgical technique that is not that invasive and results in good outcomes,” says Dr. Stilianos E. Kountakis, otolaryngologist, vice chair of the Medical College of Geor
The polycystic ovary syndrome (PCOS), the most common endocrine disorder among reproductive-age women, produces a wide variety of body changes with both physical and emotional implications for sufferers.
Many women with PCOS are found to have insulin resistance, a condition that allows excessive levels of insulin to circulate in the blood and increases the risk for Type 2 diabetes, hypertension and heart disease. PCOS is also the leading cause of androgen excess in women. Although
Common house dust may be an important source of a potentially dangerous class of chemicals called polybrominated diphenyl ethers (PBDEs), according to an exploratory study* by researchers at the National Institute of Standards and Technology (NIST) and the Environmental Protection Agency (EPA). Recent studies by others have found that PBDEs have been accumulating in human blood, fat tissue and breast milk.
PBDEs have been widely used in consumer products for years because they
A low-power, magnetic sensor about the size of a grain of rice that can detect magnetic field changes as small as 50 picoteslas–a million times weaker than the Earth’s magnetic field–has been demonstrated by researchers at the National Institute of Standards and Technology (NIST). Described in the Dec. 27 issue of Applied Physics Letters,* the device can be powered with batteries and is about 100 times smaller than current atom-based sensors with similar sensitivities, which typically wei
Prostate cancer patients with high risk cancers who are treated with both internal and external radiation and hormone treatment have a better chance of beating the disease than patients treated with radiation alone, according to a new study published in the January 1, 2005, issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.
Since the late 1980s, doctors have been inc
Study may revise clinical approach to invasive lobular breast carcinoma
Women with a rare type of advanced breast cancer who do not benefit from primary (pre-surgical) chemotherapy still have been found to do better in the long run than patients with a more common advanced breast cancer who do respond to chemotherapy.
Researchers at The University of Texas M. D. Anderson Cancer Center came to the surprising conclusion after discovering that chemotherapy response did not seem
