For the first time, a study combines measurements of abnormalities in the eye with models for assessing how well an individual can see, meaning it may be possible to program a machine to automatically produce prescriptions for corrective lenses. The model for predicting visual clarity -- based on measurements taken by today's highly accurate aberrometers -- could also enable surgeons to more accurately assess and correct the vision of patients undergoing lasik or refractive surgery.

A new prostate cancer vaccine may give hope to men with metastatic prostate cancer by enabling their immune systems to fight the disease. In recent years, the concept of vaccine immunotherapy for advanced prostate cancer has become increasingly high profile as research has expanded.

More than 40 percent of parents have used cough medicine for children younger than two -- even though it is not recommended, nor proven effective for children in this age group, a new study has found.

Researchers have sequenced the entire genetic code of 23 strains of Flavivirus, the virus that causes St. Louis encephalitis, to understand its evolutionary history. This study, published in Molecular Phylogenetics and Evolution, found that a single mutation made the virus pathogenic to humans and that the North and South American strains divided about 116 years ago.

Managing your cholesterol may also help you manage your prostate- specific antigen level. New data explores the relationship between low-density lipoprotein (LDL) cholesterol and PSA prior to beginning statin therapy.

Symptoms of depression and post-traumatic stress disorder among caregivers of deceased lung transplant patients are four-to-five times more prevalent than in the average population, according to researchers who analyzed the stress levels of caregivers, as well as their perceptions of the transplant recipients' quality of dying and death.

Early nursing intervention and implementation of effective strategies can lead to a decrease in the incidence of lymphedema, better management of chronic lymphedema and improved quality of life in breast cancer patients.

People with severe obstructive sleep apnea on commercial airline flights may have a greater risk of adverse events from cardiac stress than healthy people, according to new research.

Children with sickle cell disease have a significantly sharper decline in lung function with age when compared to other children of the same race and age. Furthermore, that loss of function appears to be linked to a restrictive rather than obstructive pattern, contrary to previous research that has focused on obstructive or asthma-like patterns in loss of lung function with sickle cell disease.

A comprehensive re-evaluation of the largest prostate cancer prevention study ever completed produced new findings suggesting that men and their doctors should consider a more aggressive approach that includes finasteride to prevent the development of prostate cancer.
