Low-dose aspirin won't prevent pregnancy loss, study shows Posted: 04 Apr 2014 12:16 PM PDT Low-dose aspirin, in general, is not beneficial for future pregnancy outcomes in women with prior pregnancy loss, a medical trial has found. However, in women with one pregnancy loss within the previous 12 months, there did appear to be a benefit. Many health care providers prescribe low-dose aspirin therapy for women who have had a pregnancy loss, and who would like to get pregnant again, the researchers noted.

Work with small peptide chains may revolutionize study of enzymes, diseases Posted: 04 Apr 2014 11:04 AM PDT Chemists, for the first time, have created enzyme-like activity using peptides that are only seven amino acids long. The breakthrough may revolutionize the study of modern-day enzymes, whose chains of amino acids usually number in the hundreds, and of neurological diseases, such as Alzheimer's, which are usually characterized by small clumps of misshapen proteins called amyloids.

Depression increases heart failure risk by 40 percent Posted: 04 Apr 2014 11:02 AM PDT Moderate to severe depression increases the risk of heart failure by 40 percent, a study of nearly 63,000 Norwegians has shown. During the study period nearly 1,500 people developed heart failure. Compared to residents with no symptoms of depression, people with mild symptoms had a 5% increased risk of developing heart failure and those with moderate to severe symptoms had a 40% increased risk.

Poor quality of life may contribute to kidney disease patients' health problems Posted: 03 Apr 2014 06:23 PM PDT In African American patients with chronic kidney disease, poor quality of life was linked with increased risks of disease progression and heart problems. Approximately 60 million people globally have chronic kidney disease (CKD). Quality of life has been well-studied in patients with end-stage kidney disease, but not in patients with CKD who do not yet require dialysis.

Surgeons use cyberknife to treat vocal cord cancer Posted: 03 Apr 2014 10:19 AM PDT Stephen Wiley, a lifelong cowboy from Terrell, has helped pioneer a new treatment for vocal cord cancer. Doctors found tumors in both his vocal cords. The $7 million Cyberknife, has a small linear particle accelerator and a robotic arm that allows it to treat tumors on any part of the body with radiation, explained his surgeon. Only about 200 of these cutting-edge machines exist in the world, most of them in the United States.
