Study Links Enzyme to Insulin Resistance

Tue Mar 19, 2002

NEW YORK (Reuters Health) - High blood levels of a naturally occurring compound involved in blood vessel function may be the "missing link" between insulin resistance, a precursor to type 2 diabetes, and heart disease.

The study findings also suggest drugs that improve insulin sensitivity may reduce levels of the compound, ADMA, and ultimately lower a person's heart disease risk.

NEW YORK (Reuters Health) - People who experience a type of excruciating back pain caused by kidney stones are more likely to be miserable in the morning than at night, a new study reports.

A kidney stone is a hard mass made up of crystals that have settled out of urine while inside the kidney.

Bleeding Ulcers on the Rise Among British Elderly

NEW YORK (Reuters Health) - Bleeding ulcers are on the rise among elderly UK patients, British researchers report.

Peptic ulcers are sores or raw areas in the lining of the stomach or the upper portion of the small intestine, known as the duodenum.

When C isn't for Cancer

by Institute of Health Sciences, L.L.C.

Every day, we get letters from HSI members and e-Alert readers with questions, comments, and concerns. We get an extraordinary amount of mail, so we can't possibly answer every one personally. But occasionally I'll notice a common thread running through the mail, a question or topic that seems to come up again and again. That's just what I've been seeing lately - and fortunately, I have a powerful answer.

Rheumatoid Arthritis Linked to Intestinal Bacteria

Tue Mar 26, 2002

By Drex Earle

ATLANTA (Reuters Health) - Certain types of intestinal bacteria could be linked to the development and progression of rheumatoid arthritis, according to the results of a new study.

In rheumatoid arthritis, the body's immune system attacks joint tissues, leading to damage in many parts of the body, including bone, cartilage and various internal organs. The disease can cause severe disabilities, particularly in older people, and its exact causes are still not known.

Psychosis with Alzheimer's May Run in Families

Mon Mar 25, 2002

By Alison McCook

NEW YORK (Reuters Health) - Many people with Alzheimer's disease also have psychotic symptoms, and a recent study shows Alzheimer's patients whose siblings have both disorders are more likely to exhibit psychosis, as well.

"This paper may be the strongest evidence to date that psychotic symptoms in Alzheimer's disease have a distinct biologic basis, with unique genetic underpinnings," said lead author Dr. Robert A. Sweet of the University of Pittsburgh, Pennsylvania.

Women with Diabetes at Risk for Sexual Problems

Wed Mar 27, 2002

NEW YORK (Reuters Health) - Women with type 1 diabetes maybe more likely to experience certain sexual problems than their healthy peers, researchers report.

Unlike the far more common type 2 diabetes, type 1 usually is diagnosed in childhood and involves anaberrant immune system attack on the insulin-producing cells in the pancreas.
