Most Hospital Performance Measures for Heart Failure Not Linked to Improved Patient Outcomes

...ce to these suggested interventions may serve as a marker of quality of care and form a foundation for quality improvement. Heart failure performance measures have been developed to provide a mechanism through which the quality of medical care can be measured and improved. The recently released ACC/AHA Clin...

Cough and Phlegm Cause Fourfold Increase in COPD Incidence

...phlegm is not an innocent symptom, but is an early marker of airflow obstruction,” said Dr. Cerveri. In addition to cough and phlegm in participants, researchers considered such factors as sex, age, dyspnea (breathlessness), smoking habits and level of education. All participants received lung function te...

Uric Acid Levels (High-Normal) Associated With Cognitive Impairment in the Elderly

...cid could potentially become a valuable biological marker for very early cognitive problems in old age. The researchers say that it's unclear why mild cognitive problems appear with high-normal uric acid because, paradoxically, uric acid also has anti-oxidant properties that are thought to be protective ...

Link Between Nanoparticles and Kidney Stones

...obe de Paris, attempted to identify a DNA chemical marker in nanoparticles. The preliminary study suggests that nanoparticles from human samples share spectroscopic characteristics with calcified bacteria that exist in freshwater lakes. However, studies could not confirm whether the nanoparticles are calcif...

Unfolded Proteins May Protect Cells from Dying

... is activated. Ryoo rigged xbp1 with a fluorescent marker that would light up whenever this alternatively spliced version of xbp1 was made, allowing him to detect every time the cell initiated an unfolded protein response. 'Our work shows that the unfolded protein response is a protective pathway, and th...

Olive Oil Addition in Diet may Cut Cancer Risk

...duction in the substance called 8oxodG, which is a marker of oxidative damage to DNA cells. Oxidative damages occurs when byproducts of metabolism called reactive oxygen species overwhelm the body`s antioxidant defenses. Olive oil contains a number of compounds, called phenols, believed to act as powerfu...

Abstinence from Alcoholism Pays Off, Says New Study

...ks of abstinence. The increase of the nerve cell marker correlated with the patients performing better in a test of attention and concentration. Only one patient seemed to continue to lose some brain volume, and this was also the patient who had been an alcoholic for the longest time. "The core message ...

Study Results on Stool DNA Testing for Colon Cancer Announced

Gene Linked With Aggressive 'Wet' Form Of AMD

...d in the eyes of patients who carry HTRA1. "The marker we have identified is very much associated with AMD, but no one has ever pinpointed the clinical features of the gene. We need to conduct further analysis in order to understand the biological mechanisms," said Hoh. Source-Eurekalert SI...

Millions with Arthritis May Benefit from Bone Loss Drug

...r marks. Blood tests were also used to check for a marker of cartilage breakdown known as CTX-II. CTX-II is released in the bloodstreams of people with osteoarthritis when cartilage begins to fray. How fast and to what degree cartilage breaks down can be approximated by levels of CTX-II. “The blood tes...

Onions, Garlic may Reduce the Risk of Cancer

...say onion and garlic consumption could simply be a marker for a healthier lifestyle and a diet high in a variety of potentially cancer-fighting herbs and vegetables. However, the protective effect of onions and garlic against cancer remained significant even when they controlled for total vegetable intake...

Regulatory Mechanism for Tumor Suppressor Protein Identified

...tified enzyme might also be useful as a diagnostic marker for cancer." Responsible for tumor suppression throughout the body, the p53 protein has been found to be mutated and dysfunctional in more than half of human cancers. When working properly, p53 acts by binding to DNA to activate genes that direct ce...

Children and Chronic Kidney Disease

...ITH END-STAGE KIDNEY DISEASE Anemia, an important marker of ill health, is persistently worse in African-American children with end-stage kidney disease than in their white counterparts, according to results of a study by scientists at the Johns Hopkins Children's Center.
