Obesity and Memory, mRNA, Body Composition, Comorbidity Scale
Obesity and Memory, mRNA, Body Composition, Comorbidity Scale
1. Briefly describe the purpose of this protocol. First purpose of the study is to
 understand the inheritance of morbid obesity.

 2. Briefly summarize how participants are recruited. Volunteers will first learn of LABS-2a
 research opportunity at the Bariatric Surgery Informational meetings.

 3. Briefly describe the procedures subjects will undergo.

 Participants will be asked to complete a set of memory tests. Fat and Liver samples will
 be removed during their weight loss surgery, specifically for this research study.

 4. If applicable, briefly describe survey/interview instruments used. Memory tests will be
 performed to assess cognition.

 5. Briefly describe how the data will be analyzed to address the purpose of the protocol.

 The memory test data collected and compared against well established norms. Tissue samples
 will stored in a repository to be genetically studied for an indefinite amount of time.
 Genetic studies will be related to the disease of obesity and associated comorbidities
 brought on by the disease.
1. Briefly describe the purpose of this protocol. First purpose of the study is to
 understand the inheritance of morbid obesity. If a gene or genes cause morbid obesity
 can be found, the diagnosis and treatment of morbid obesity may be improved. Second
 purpose is to learn more about the effects of weight loss on dementia, body composition,
 and comorbidity.

 2. Briefly summarize how participants are recruited. Volunteers will first learn of LABS-2a
 research opportunity at the Bariatric Surgery Informational meetings. Subjects who
 express interest, will be screened through an IRB-approved informal telephone interview.
 If no exclusion criteria are identified, volunteers will be asked to provide
 IRB-approved consent. Recruitment will occur irrespective of race, religion or color.

 3. Briefly describe the procedures subjects will undergo. Participants will be asked to
 complete a set of memory tests. These memory tests will be recorded on audio tape.
 BodPod will be used to measure their muscle, bone, and fat. The BodPod is an upright
 capsule that will enclose around a subject completely. BodPod uses the movement of air
 to measure muscle, and fat volumes. Participation in the memory testing portion and the
 BodPod portion of the research is optional. Fat and Liver samples will be removed during
 their weight loss surgery, specifically for this research study.

 4. If applicable, briefly describe survey/interview instruments used. Memory tests will be
 performed to assess cognition. The Wechsler Memory Scale-Third Edition (WMS-III) and the
 Mini Memory State Examination (MMSE) will be the validated memory tests used. The
 WMS-III tests logical memory by having subjects recall short stories that were just read
 to them. The MMSE involves performing a set of requests that test orientation to time
 and place, immediate recall, short term verbal memory, calculation, language and
 construct ability.

 The memory test data collected and compared against well established norms. Tissue samples
 will stored in a repository to be genetically studied for an indefinite amount of time.
