Severity of tuberculosis in patients with type 2 diabetes

A collaborative study between A∗STAR Infectious Diseases Labs and the University of Massachusetts Chan Medical School reveals that elevated glycerol levels contribute to increased severity of tuberculosis (TB) in experimental models with type 2 diabetes. TB caused 1.3 million deaths globally in 2022. Type 2 diabetes is associated with higher mortality rates due to TB, and patients with type 2 diabetes have a higher chance of TB relapse after treatment. The study found that type 2 diabetes led to more bacteria, tissue damage, and deaths when infected with Mycobacterium tuberculosis (Mtb), the pathogen causing TB. Elevated blood glycerol emerged as a crucial factor in the TB-type 2 diabetes interaction. Blocking Mtb’s ability to use glycerol for metabolism decreased lung damage severity, indicating that Mtb utilizes glycerol to drive TB disease severity in type 2 diabetes. This could pave the way for developing innovative therapeutics targeting elevated glycerol in TB patients with type 2 diabetes, addressing their heightened susceptibility to TB, particularly in the face of increasing drug resistance. The study identifies Mtb’s glycerol kinase as a potential TB drug development target.

What people thought about us

“As Director of Surgical Services Departments there has been considerable changes have occurred in my department and Anesthesia Experts has always risen to meet our demands of our facility. They have been very pro-active in meeting the increase volumes allowing us to keep our surgeons and patients very satisfied with our services.”

“Before AE took over the anesthesia department was described by the surgeons as the worst in the history of our hospital. The prior management company was having a cancelled surgery per day. I am happy to report there has not been one since they have taken over the department. Additionally we have seen a 905 reduction if requested preop
lab tests. The anesthesia department is now the very best hospital department in our entire facility.”

“Anesthesia Experts has provided consistent anesthesia providers who display a high degree of integrity, responsibility and professionalism. They have become a more valuable part of our facility and community.”

LR CEO 150 beds TX

“Even though they are physically located 1000 miles away Anesthesia Experts just does not provide great anesthesia coverage they personally engage surgeons to increase their business. Last year my surgical volume rose by 24% and we are currently 50% ahead of last year and all of that growth is organic.”

JE FACHE CEO AL 92 bed hospital

“Anesthesia Experts is more responsive than anyone I have dealt with. They are available by phone whenever needed and will be on site for any need or request and has been on site to address issues before we can make the request.”

SW CEO 25 beds NM

“While problems are extremely rare when they do occur Anesthesia Experts quickly and professionally implements a solution. Our surgical volume has grown over 100 cases per month and now our GI docs want to perform all of their endoscopies in our hospital instead of their GI lab that they own!”

SP CEO 346 beds AL

“Our anesthesia department was a thorn in my side that kept me awake at night. Anesthesia Experts swept in and brought order to our mess and our department was quickly redirected.”
