If you’ve been feeling bone pain, your doctor may take one look at that stiff, swollen joint or that loss of motion and suspect that what you’ve got is the inevitable onset of age-related osteoarthritis (OA) or the autoimmune disorder that leads to rheumatoid arthritis (RA).
But to refine that diagnosis,
The very air we breathe might be adding to our risk for Alzheimer’s disease (AD), according to a study published online Sept. 5, 2016 in the journal PNAS. The researchers autopsied the brains of 37 older city dwellers and discovered abnormally high concentrations of magnetite, an iron oxide found in
The word “pre” may sound innocuous, but a prediabetes diagnosis is one to be taken very seriously. According to cardiologist Karol Watson, MD, UCLA Medical Center, the leading cause of death for people with diabetes is heart disease.
“The damage doesn’t just start once diabetes is diagnosed,” explains Dr. Watson. “The
As a rule, upper back pain is unusual, since the upper back is structurally stronger than the lower back and also isn’t as mobile, due to being connected to the rib cage. This lack of motion affords it some protection against the bending-twisting types of injury you might sustain in
Eggs May Reduce Stroke Risk
Eating up to one egg a day has been shown to have no association with heart disease, yet it may reduce risk of stroke by 12%, research shows. The meta-analysis, which included studies between 1982 and 2015 focused on the relationship between egg intake and heart
According to a recent study (Hepatology, Oct. 3, 2016), the number of hospitalizations for cirrhosis of the liver nearly doubled from 371,000 in 2001 to 659,000 in 2011. Cirrhosis causes healthy tissue to be gradually replaced by scar tissue that impedes blood flow through the liver, impacting liver function and
Osteoarthritis (OA) and rheumatoid arthritis (RA) affect the lives of millions of people worldwide. OA is known for progressive damage to joint cartilage, which causes changes in the surrounding tissues. RA is a chronic disease that causes pain, stiffness, swelling, and limits range of motion and function of many joints;
A new clinical trial and a review of the evidence both suggest eating tree nuts may help fight diabetes. Tree nuts include walnuts, hazelnuts, almonds, Brazil nuts, cashews, pecans, pine nuts, macadamias and pistachios. One study reported that pistachios improved markers of blood sugar and inflammation in people at risk
