Dr. Sydney Burwell, Dean of Harvard Medical School 1956

My students are dismayed when I say to them "Half of what you are taught as medical students will in 10 years have been shown to be wrong.
And the trouble is, none of your teachers know which half."

Mixed Bag

High-calorie feeding may slow progression of ALS
Increasing the number of calories consumed by patients with amyotrophic lateral sclerosis (ALS) may be a relatively simple way of extending their survival. A phase 2 clinical trial led by Massachusetts General Hospital (MGH) physicians found that ALS patients receiving a high-calorie, high-carbohydrate tube-feeding formula lived longer with fewer adverse events than participants who received a standard formula designed maintain their weight. While the small size of the trial indicates results need to be interpreted with caution, the authors are optimistic that improved nutrition could make a significant difference for patients with ALS.

Do obesity, birth control pills raise risk of multiple sclerosis?
For the obesity study, BMI was calculated for 210 people with MS and 210 people of the same age and sex who did not have MS at ages 15 and 20 and at the time of the study. The study found that people who are obese at age 20 are twice as likely to later develop MS as people who are not obese. The study found that people with higher BMI levels also had higher levels of leptin, a hormone made by fat tissue that regulates weight, appetite and immune response.

Women who had used hormonal contraceptives were 35 percent more likely to develop MS than those who did not use them. Those who had used the contraceptives but had stopped at least one month before symptoms started were 50 percent more likely to develop MS. MedicalXpress

Transplanting thymus cells into patients may repair and restore the immune system
Studies show that transplanting thymus cells into patients can be an effective way to repair and restore the immune system; however the lack of a source for these specialised cells represents a major barrier. In the previous studies, scientists used cells from newborn babies that had been removed as a normal part of heart surgery. Cells from adult donors are shown not to have the same effect. The THYMISTEM team seeks to overcome this by finding new methods of producing thymus stem cells in the lab as an alternative source of cells for therapy. MedicalXpress
