Keeping the Weight Off

by William Yates, M.D. in Brain Posts

Weight loss and maintenance of weight loss is difficult if not nearly impossible for most people.A registry of individuals who have lost 30 pounds or more and maintained their weight loss over a year exists in the U.S. This research effort is known as the National Weight Control Registry. It currently has over 10,000.I was looking at some of the published research results from this study. A paper published in 2012 used cluster analysis to identify sub-types of individuals with successful long-te........ Read more »

Obesity Surgery: VA Outcome Study

by William Yates, M.D. in Brain Posts

Weight loss (bariatric) surgery is likely to become increasingly important to address the obesity epidemic in the U.S. and other nations.There are several types of surgical techniques used for bariatric surgery.One of the most invasive is the Rous-en-Y gastric bypass (RYG) operation. This operation involves bisection of the small intestine and reattachment of the upper section to a position lower down the small intestine. This provides for a shorter distance for food to be absorbed.Less invasive........ Read more »

Dyslexia Improvement in Medication Trial

by William Yates, M.D. in Brain Posts

Dyslexia or developmental reading disorder is a common learning disorder affecting about 5% of the school age population.Treatment of dyslexia is difficult and typically is focused on special education classes and reading exercises.Medication treatment for dyslexia is nearly unheard of as no FDA-approved drug is available for the condition.However, a recent randomized clinical drug trial found evidence to support the potential use of atomoxetine for dyslexia.Atomoxetine is a drug approved for at........

The PROCAMIO Trial – IV Procainamide vs IV Amiodarone for the Acute Treatment of Stable Wide Complex Tachycardia

by Rogue Medic in Rogue Medic

This is a very interesting trial that may surprise the many outspoken amiodarone advocates, but it should not surprise anyone who pays attention to research.

ALPS showed that we should stop giving amiodarone for unwitnessed shockable cardiac arrest. The lead researcher is still trying to spin amiodarone for witnessed shockable cardiac arrest, even though the results do not show improvement in the one outcome that matters – leaving the hospital with a brain that still works.[1],[2],[3]...

Acupuncture vs intravenous morphine in the management of acute pain in the ED

by Rogue Medic in Rogue Medic

Should we have people providing "fake" acupuncture in the Emergency Department?

If so, how should we do this?

Since it is not the acupuncture, but the patient's reaction to the "ceremony of the placebo" that appears to be providing the pain relief, how many different ways might we vary the "treatment" to improve the placebo effect?... Read more »

Update on clinical trials and treatments for RCC

by Joana Guedes in BHD Research Blog

Renal cell carcinoma (RCC) is the most common type of kidney cancer and although the majority of cases are sporadic approximately 3% of cases are caused by genetic conditions such as BHD, VHL, HLRCC and TSC (Randall et al., 2014). These inherited forms of RCC have provided great insights into sporadic cancer genetics. BHD patients can develop multiple kidney tumours. In most cases these tumours are small local RCCs that can be surgically removed. However, these treatments are not without risk,........ Read more »

BHD syndrome and thyroid conditions

by Joana Guedes in BHD Research Blog

Dong et al., (2016) have recently reported two BHD syndrome patients also affected with papillary thyroid cancer. Lesions were bilateral and multifocal and small lymph node metastases occurred. Due to the small number of patients in the study the authors are unsure whether thyroid cancer in BHD patients is susceptible to exhibiting bilaterally and lymph node metastasis. However, they suggest considering thyroidectomy and prophylactic lymph node dissection for thyroid cancer patients with BHD. Th........ Read more »
