Screening has had “little impact” on falling breast cancer deaths

Breast screening in the Netherlands seems to have had a marginal effect on breast cancer mortality over the past 24 years, suggests research in The BMJ. Their findings show that screening would be associated with up to 5% reductions in breast cancer mortality in women aged 50 and over, whereas improved treatments would be associated with a 28% reduction. And they point out that overdiagnosis…

Gluten-free diet - hope or hype?

Walk into the local grocery store and you’re likely to find an array of products with the words “gluten-free” splashed across the label. Everything from cereal to frozen pizza to pasta — and even water — is getting the gluten-free treatment. According to a recent survey, 30 percent of Americans said they were cutting down or avoiding gluten altogether. And yet, only four percent of the…

Treatment window for strokes might be larger than previously thought

Treating stroke has long been governed by the clock. If it has been less than three hours since the onset of symptoms, the clot-busting drug t-PA will likely work. If it has been four and a half hours, some selected patients might benefit. However, if it has been more than six hours, treatment options have been few. Now that conventional wisdom has been turned on its head. The final results of…

This is why testicular cancer is so responsive to chemo

Cornell researchers have taken a major step toward answering a key question in cancer research: Why is testicular cancer so responsive to chemotherapy, even after it metastasizes? Professional cyclist Lance Armstrong, for example, had testicular cancer that spread to his lung and brain, yet he made a full recovery after conventional chemotherapy. The key to such success appears to lie in the…

Prostate Health Index drastically cuts down biopsy rate

A study published in Prostate Cancer and Prostatic Diseases demonstrated that physicians elected to perform fewer biopsies when Prostate Health Index (phi) testing was included in their overall, routine, clinical assessment. Phi testing is recommended for men presenting with elevated serum total prostate-specific antigen (PSA) in the 4-10 ng/mL range and a non-suspicious digital rectal exam…

Breast cancer treatment costs to strain medicare in the near future

With cancer care costs projected to increase 32% from 2010 to 2020, researchers are working to determine the main drivers of costs for treating breast cancer. Breast cancer accounted for the highest proportion (13%) of the $124.6 billion in Medicare money spent on cancer care in 2010. In a study led by Ami Vyas, PhD, MS, MBA (currently at the University of Rhode Island) and published in the…

Secrets of Ebola uncovered - in the heart of a devastating outbreak

In a comprehensive and complex molecular study of blood samples from Ebola patients in Sierra Leone, published in Cell Host and Microbe, a scientific team led by the University of Wisconsin–Madison has identified signatures of Ebola virus disease that may aid in future treatment efforts. Conducting a sweeping analysis of everything from enzymes to lipids to immune-system-associated molecules,…

Asthma and food allergies predictable at age one

Children at one year old who have eczema or atopic dermatitis (AD) and are sensitized to an allergen are seven times more likely than other infants to develop asthma, and significantly more likely to have a food allergy by age three. This new finding from the Canadian CHILD Study will help doctors better predict which children will develop asthma and allergies, according to a paper published by…

How old is too old to perform brain surgery?

People sometimes joke that easy tasks are “not brain surgery.” But what happens when it actually is brain surgery? How old is too old to be a neurosurgeon? In a new Mayo Clinic Proceedings study, most neurosurgeons disagreed with an absolute age cutoff, but half favored additional testing for neurosurgeons 65 and older. Some professions, including commercial pilots, FBI agents and air traffic…

Primary care consultations last less than 5 minutes for half the world’s population

Primary care consultations last less than 5 minutes for half the world’s population, but range from 48 seconds in Bangladesh to 22.5 minutes in Sweden, reveals the largest international study of its kind, published in the online journal BMJ Open. Shorter consultation times have been linked to poorer health outcomes for patients and a heightened risk of burnout for doctors. And as demand for…

Mapping brain connectivity with MRI may predict cardiac arrest survival

A new study led by Johns Hopkins researchers found that measures of connectivity within specific cerebral networks were strongly linked to long-term functional outcomes in patients who had suffered severe brain injury following a cardiac arrest. A description of the findings, published in October in the journal Radiology, suggests that mapping and measuring such connectivity may result in highly…

Teenage girls more likely to self-harm than boys

There has been a sharp rise in self-harm reported in general practices for girls aged between 13-16 years from 2011 to 2014, compared with boys of the same age. In socially deprived areas, referrals to mental health specialist services were fewer, although self-harm rates were higher, finds a study published by The BMJ.

Immune response to ovarian cancer may predict survival

A group of international cancer researchers led by investigators from Mayo Clinic and University of New South Wales Sydney has found that the level of a type of white blood cell, called tumor-infiltrating lymphocytes, present in the tumors of patients with high-grade ovarian cancer may predict a patient’s survival. “We know that a type of tumor-infiltrating lymphocyte called cytotoxic CD8 are…

Higher vitamin D dose increases bone density in premature babies

Results of a University of Nebraska Medical Center study found if the standard supplementation of 400 IUs of vitamin D is increased to 800 IUs daily there are reductions in the number of premature and preterm babies with extremely low bone density. Physicians have been prescribing vitamin D in premature and preterm infants in neonatal intensive care units (NICU) to prevent rickets, a disease…

Do common acid reflux medications promote chronic liver disease?

Approximately 10 percent of the general population take a proton pump inhibitor (PPI) drug to block stomach acid secretions and relieve symptoms of frequent heartburn, acid reflux and gastroesophageal reflux disease. That percentage can be as much as seven times higher for people with chronic liver disease. Researchers at University of California San Diego School of Medicine have discovered…

How to decrease the discard rate of donated organs

A new study indicates that many donated organs that are discarded might be suitable for transplantation if certain steps are taken to limit damage following donation. The findings appear in an upcoming issue of the Journal of the American Society of Nephrology (JASN). In most cases in the United States, transplant organs come from donors following brain death, in which all the functions of the…

No clear evidence that most new cancer drugs extend or improve life

The majority of cancer drugs approved in Europe between 2009 and 2013 entered the market without clear evidence that they improved survival or quality of life for patients, finds a study published by The BMJ. Even where drugs did show survival gains over existing treatments, these were often marginal, the results show. Many of the drugs were approved on the basis of indirect (‘surrogate’)…

Odor identification problems may be a warning bell for dementia

A long-term study of nearly 3,000 adults, aged 57 to 85, found that those who could not identify at least four out of five common odors were more than twice as likely as those with a normal sense of smell to develop dementia within five years. Although 78 percent of those tested were normal – correctly identifying at least four out of five scents – about 14 percent could name just three out…
