A marker of the likely course of diabetic nephropathy (DN) has been found. An 18-year study, published in the open access journal BMC Medicine, has shown that Immunoglobulin M (IgM) is a reliable predictor of cardiovascular complications in DN patients. Omran Bakoush, MD, PhD, led a team of researchers from Lund University, Sweden, who carried out the research. He said, "To our knowledge, this study is the first to investigate the impact of increased urine IgM excretion on DN disease progression in type 1 diabetic patients. We found that those with increased urinary IgM excretion had a higher mortality from cardiovascular causes, and higher disease progression rate to end-stage renal disease.
A study, "Sibling risk of Pediatric Obstructive Sleep Apnea Syndrome and Adenotonsillar Hypertrophy, " in the Aug. 1 issue of the journal SLEEP indicates that children have an increased risk of developing obstructive sleep apnea (OSA) if they have at least one sibling who has been diagnosed with the sleep disorder. Results indicate that after accounting for socioeconomic status, age, and geographic region, the sibling risk of pediatric OSA was extremely high, with a standardized incidence ratio of 33.2 in boys and 40.5 in girls who had at least one sibling with an OSA diagnosis. A total of 854 boys and 627 girls who were 18 years of age or younger had a first hospital diagnosis of pediatric OSA during the study period;
Brain scientists and cardiac surgeons at Johns Hopkins have evidence from 227 heart bypass surgery patients that long-term memory losses and cognitive problems they experience are due to the underlying coronary artery disease itself and not ill after-effects from having used a heart-lung machine. Researchers say their latest findings explain study results presented last year, which showed that the heart-lung machines - used to pump blood and supply the body with oxygen while the heart is stopped during surgery - did not cause postoperative long-term brain deficits. "Our results hammer home the message that heart-lung machines are not to be blamed for cognitive declines observed years later in people who have had bypass surgery, " says lead study investigator Ola A.
There is mounting evidence that omega-3 fatty acids from fish or fish oil supplements not only help prevent cardiovascular diseases in healthy individuals, but also reduce the incidence of cardiac events and mortality in patients with existing heart disease. A new study, published in the August 11, 2009, issue of the Journal of the American College of Cardiology, extensively reviews data from a broad range of studies in tens of thousands of patients and sets forth suggested daily targets for omega-3 consumption. "This isn't just hype; we now have tremendous and compelling evidence from very large studies, some dating back 20 and 30 years, that demonstrate the protective benefits of omega-3 fish oil in multiple aspects of preventive cardiology, " said Carl Lavie, M.
A new chemical imaging technique could one day help in the fight against atherosclerosis, suggests research published in the August 2009 edition of the Journal of the Royal Society Interface. Atherosclerosis is the disease underlying most heart attacks and strokes and it is characterised by lesions in the arteries, made of fats, collagen and cells. The lesions cause artery walls to harden and thicken, which severely restricts the flow of blood around the body and they can also rupture, leading to heart attacks and strokes. Understanding the precise chemical composition of an individual's lesions is important because the ones with higher levels of a type of fat called cholesteryl ester are more prone to rupture.
Low blood pressure is also known as hypotension. For millions of people who suffer from hypertension (high blood pressure) hypotension may seem great. If symptoms are mild hypotension usually requires no treatment. However, it can cause serious heart disorders, fainting and also lead to neurological and endocrine disorders. If hypotension is severe key organs can become deprived of oxygen and nutrients and the body can go into shock, a life-threatening condition. According to Medilexicon's medical dictionary, hypotension is "1. Subnormal arterial blood pressure. 2. Reduced pressure or tension of any kind." What is blood pressure? The heart is a muscle that pumps blood around the body continuously.
