  • This slide illustrates the spectrum of care that comes from the Center. The Center is unique because it has a focus on prevention AND treatment. Many of you may be familiar with the Borden Center name. The Borden Center has melded into the prevention piece of the Center. We are very active in the community representing in several community initiatives and projects such as the Healthy and Fit project; Action for Healthy Kids. We are continuously seeking outside funding to support our efforts in this area. To date we have one fund grant and 3 pending proposals. Our superb bariatric program is in the umbrella of the Center. All patients that enter this program come through a thorough assessment clinic and are part of the Center’s family. Dr. Murray and Dr. Ihuoma Eneli are working on several research projects. With some funding from CRI, we are creating a database that is collecting detailed data on our patients that will be necessary for research.

  •  
  •  
  • Do I have to check labs? Consider Fasting Lipid Profile age >=2 years , Additional hepatic function and fasting glucose should be considered at age >= 10years. Clinical judgment may dictate additional labs in the younger child with higher risk. Fasting Lipid Profile ALT, AST, Fasting glucose > 95% Fasting Lipid Profile ALT, AST, Fasting glucose 85-94% With risk factors Fasting Lipid Profile 85-94% No risk factors Labs BMI Percentile
