Low-income patients with obstructive sleep apnea are less likely to start CPAP therapy

A study in the April 1 issue of the journal SLEEP demonstrates that low socioeconomic status independently predicts the poor acceptance of continuous positive airway pressure (CPAP) therapy for obstructive sleep apnea, and patients with higher incomes are more likely to begin treatment.

New light-based system reveals breast tumor oxygen status

Light directed at a breast tumor through a needle can provide pathologists with biological specifics of the tumor and help oncologists choose treatment options that would be most effective for that individual patient.

Protein ferritin in blood may hold key to stopping tumor growth in cancer patients

A recent discovery by researchers at Wake Forest University School of Medicine could clear the way for a new drug that inhibits tumor growth in cancer patients and could potentially help in the healing of wounds.

Accurate assessment of heart disease leads to earlier, more aggressive therapy

In a study comparing the ability of various medical techniques to accurately determine the extent of heart disease and stratify patients according to disease severity, researchers found that myocardial perfusion testing with gated single photon emission computed tomography (gated SPECT) was a more accurate predictor of prognosis in chronic ischemic heart disease (IHD)-a painful condition caused by a temporary reduction of oxygen-rich blood to the heart.

A magic bullet for superbugs

Attaching an antimicrobial drug, which is activated by light, to a peptide that binds to bacteria and stops them making toxins, produced a "magic bullet" that was highly effective at killing the superbug, methicillin-resistant Staphylococcus aureus (MRSA).

New radiation-free targeted therapy detects and eliminates breast cancer tumors in mice

Combining a compound known as a gallium corrole with a protein carrier results in a targeted cancer therapy that is able to detect and eliminate tumors in mice with seemingly fewer side effects than other breast-cancer treatments, says a team of researchers from the California Institute of Technology (Caltech), the Israel Institute of Technology (Technion) and the Cedars-Sinai Medical Center.

Environment plays role in hypoplastic left heart syndrome

A congenital heart disease that often leads to death in newborns is significantly more common during the summer, leading researchers to believe that the environment, and not just genes that affect the heart, may play a role in causing "mini-epidemics" of this disease.

Missing enzyme GNSOR conveys major heart protection in pre-clinical work

Mice born without a certain enzyme can resist the normal effects of a heart attack and retain nearly normal function in the heart's ventricles and still-oxygenated heart tissue, according to a study by researchers at Duke University Medical Center.

Researchers find direct link between oxidative stress and inflammatory signals in the blood

The finding could lead to improved strategies for preventing several diseases by including antioxidants in the diet and for reducing the impact of inflammation in critically ill patients by adding cysteine to intravenous or tube feeding.

Genetic variations may determine lung function and susceptibility to maternal smoking

A tiny variation within a single gene can determine not only how quickly and well lungs grow and function in children and adolescents, but how susceptible those children will be to exposure to second-hand tobacco smoke, even in utero, according to researchers from the University of Southern California.
