Mayo Clinic Proceedings study finds little variance in survival

11.03.2003


A long-term study of patients in Rochester, Minn., with the eating disorder anorexia nervosa found that their survival rates did not differ from the expected survival rates of others of the same age and sex.

The results, published in the March issue of Mayo Clinic Proceedings, add to the knowledge of anorexia nervosa and point to other areas that need greater study from researchers.

"Although our data suggest that overall mortality is not increased among community patients with anorexia nervosa in general, these findings should not lead to complacency in clinical practice because deaths do occur," says L. Joseph Melton, III, M.D., Mayo Clinic epidemiologist and an author of the report.



Dr. Melton notes the need for more research to define the association of suicide and alcoholism in patients with anorexia nervosa.

Many clinical studies of patients with anorexia nervosa have reported higher death rates, due to the fact that many patients studied are at tertiary care centers, where their disease is more advanced than those seen in a primary care setting, such as many of the patients studied in the Mayo Clinic study.

To obtain a more representative picture, Mayo Clinic researchers examined the survival of a population-based cohort of residents in Rochester, who met diagnostic criteria for anorexia nervosa from 1935 to 1989 and who were monitored for up to 63 years. Patient records were reviewed using the Rochester Epidemiology Project.

Of the 208 patients (193 women and 15 men) studied, one woman died of complications of anorexia nervosa, two women committed suicide and six patients (five women and one man) died of complications of alcoholism.

"More research is needed to define the association of suicide and alcoholism in patients with anorexia nervosa," Dr. Melton said. "Early recognition of anorexia nervosa and its appropriate treatment are warranted."

The study was supported in part by a research grant from the National Institutes of Health, U.S. Public Health Service.

In an editorial in the same issue of Mayo Clinic Proceedings, Patrick Sullivan, M.D., of the Departments of Genetics and Psychiatry, Carolina Center for Genome Sciences at the University of North Carolina at Chapel Hill, writes that the study advances the knowledge of the long-term consequences of anorexia nervosa.

"It adds to the impressive body of work on the epidemiology of eating disorders in Rochester, Minn.," Dr. Sullivan writes. He said the study raises a number of questions that further studies need to address about patients with anorexia nervosa.

"However, the value of their study is twofold. It seems increasingly clear that anorexia nervosa exists along a spectrum," Dr. Sullivan writes. "This distinction is not captured by the criteria generally used for classifying anorexia nervosa. In addition, it seems plausible that prognosis varies with illness severity."

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
