A plant-based diet for the prevention and treatment of type 2 diabetes
McMacken, Michelle; Shah, Sapana
The prevalence of type 2 diabetes is rising worldwide, especially in older adults. Diet and lifestyle, particularly plant-based diets, are effective tools for type 2 diabetes prevention and management. Plant-based diets are eating patterns that emphasize legumes, whole grains, vegetables, fruits, nuts, and seeds and discourage most or all animal products. Cohort studies strongly support the role of plant-based diets, and food and nutrient components of plant-based diets, in reducing the risk of type 2 diabetes. Evidence from observational and interventional studies demonstrates the benefits of plant-based diets in treating type 2 diabetes and reducing key diabetes-related macrovascular and microvascular complications. Optimal macronutrient ratios for preventing and treating type 2 diabetes are controversial; the focus should instead be on eating patterns and actual foods. However, the evidence does suggest that the type and source of carbohydrate (unrefined versus refined), fats (monounsaturated and polyunsaturated versus saturated and trans), and protein (plant versus animal) play a major role in the prevention and management of type 2 diabetes. Multiple potential mechanisms underlie the benefits of a plant-based diet in ameliorating insulin resistance, including promotion of a healthy body weight, increases in fiber and phytonutrients, food-microbiome interactions, and decreases in saturated fat, advanced glycation endproducts, nitrosamines, and heme iron.

Randomized Pilot Trial of Bariatric Surgery Versus Intensive Medical Weight Management on Diabetes Remission in Type 2 Diabetic Patients Who Do NOT Meet NIH Criteria for Surgery and the Role of Soluble RAGE as a Novel Biomarker of Success
Parikh, Manish; Chung, Mimi; Sheth, Sheetal; McMacken, Michelle; Zahra, Tasneem; Saunders, John K; Ude-Welcome, Aku; Dunn, Van; Ogedegbe, Gbenga; Schmidt, Ann Marie; Pachter, H Leon
OBJECTIVE: To compare bariatric surgery versus intensive medical weight management (MWM) in patients with type 2 diabetes mellitus (T2DM) who do not meet current National Institutes of Health criteria for bariatric surgery and to assess whether the soluble form of receptor for advanced glycation end products (sRAGE) is a biomarker to identify patients most likely to benefit from surgery. BACKGROUND: There are few studies comparing surgery to MWM for patients with T2DM and BMI less than 35. METHODS: Fifty-seven patients with T2DM and BMI 30 to 35, who otherwise met the criteria for bariatric surgery were randomized to MWM versus surgery (bypass, sleeve or band, based on patient preference). The primary outcomes assessed at 6 months were change in homeostatic model of insulin resistance (HOMA-IR) and diabetes remission. Secondary outcomes included changes in HbA1c, weight, and sRAGE. RESULTS: The surgery group had improved HOMA-IR (-4.6 vs +1.6; P = 0.0004) and higher diabetes remission (65% vs 0%, P < 0.0001) than the MWM group at 6 months. Compared to MWM, the surgery group had lower HbA1c (6.2 vs 7.8, P = 0.002), lower fasting glucose (99.5 vs 157; P = 0.0068), and fewer T2DM medication requirements (20% vs 88%; P < 0.0001) at 6 months. The surgery group lost more weight (7. vs 1.0 BMI decrease, P < 0.0001). Higher baseline sRAGE was associated with better weight loss outcomes (r = -0.641; P = 0.046). There were no mortalities. CONCLUSIONS: Surgery was very effective short-term in patients with T2DM and BMI 30 to 35. Baseline sRAGE may predict patients most likely to benefit from surgery. These findings need to be confirmed with larger studies.ClinicalTrials.gov ID: NCT01423877.

Tuberculous prostate abscesses in an immunocompetent patient: A dramatic presentation of disseminated tuberculosis
Johnson, Matthew G; Caplan-Shaw, Caralee E; McMacken, Michelle
Genitourinary tuberculosis (TB) is infrequently reported in the United States, but is a common form of extrapulmonary TB that often goes unnoticed due to its insidious and sometimes asymptomatic presentation. Prostate involvement and the development of tuberculous prostatic abscesses have been reported in the literature largely in association with human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS). We report a case of disseminated TB involving tuberculous prostatic abscesses in a patient without HIV/AIDS, presenting with sepsis and urinary symptoms. This patient had simultaneous prostatic, peritoneal, pulmonary, and likely renal TB, serving as a reminder to clinicians that multi-organ presentations of TB do occur in patients without overt immunosuppressive conditions. This case also highlights the importance of considering the diagnosis of genitourinary TB in patients with risk factors for TB presenting with vague, long-standing urinary symptoms.

How to deliver high-quality obesity counseling in primary care using the 5As framework
Schlair, S; Moore, S; McMacken, M; Jay, M
* Objective: To review the content of the 5As of obesity counseling for primary care physicians as well as strategies to efficiently address the 5As during a typical 20-minute visit. * Methods: Review of the literature. * Results: Obese patients are evaluated in the primary care setting for multiple weight-related comorbidities and often seek help from their primary care providers to lose weight. Several studies have suggested that physicians and other providers do not adequately counsel obese patients about their weight because of barriers such as poor reimbursement, lack of obesity-related counseling skills, and lack of time. The 5As (Assess, Advise, Agree, Assist, Arrange) is an evidence-based, behavior-change counseling framework endorsed by the Centers for Medicare and Medicaid Services and the United States Preventive Services Task Force. * Conclusion: With the recent announcement that Medicare will now cover intensive behavioral counseling for obese patients, more providers may be interested in gaining the necessary skills to provide high-quality weight management counseling

Does a preoperative medically supervised weight loss program improve bariatric surgery outcomes? A pilot randomized study
Parikh, Manish; Dasari, Meena; McMacken, Michelle; Ren, Christine; Fielding, George; Ogedegbe, Gbenga
BACKGROUND: Many insurance payors mandate that bariatric surgery candidates undergo a medically supervised weight management (MSWM) program as a prerequisite for surgery. However, there is little evidence to support this requirement. We evaluated in a randomized controlled trial the hypothesis that participation in a MSWM program does not predict outcomes after laparoscopic adjustable gastric banding (LAGB) in a publicly insured population. METHODS: This pilot randomized trial was conducted in a large academic urban public hospital. Patients who met NIH consensus criteria for bariatric surgery and whose insurance did not require a mandatory 6-month MSWM program were randomized to a MSWM program with monthly visits over 6 months (individual or group) or usual care for 6 months and then followed for bariatric surgery outcomes postoperatively. Demographics, weight, and patient behavior scores, including patient adherence, eating behavior, patient activation, and physical activity, were collected at baseline and at 6 months (immediately preoperatively and postoperatively). RESULTS: A total of 55 patients were enrolled in the study with complete follow-up on 23 patients. Participants randomized to a MSWM program attended an average of 2 sessions preoperatively. The majority of participants were female and non-Caucasian, mean age was 46 years, average income was less than $20,000/year, and most had Medicaid as their primary insurer, consistent with the demographics of the hospital's bariatric surgery program. Data analysis included both intention-to-treat and completers' analyses. No significant differences in weight loss and most patient behaviors were found between the two groups postoperatively, suggesting that participation in a MSWM program did not improve weight loss outcomes for LAGB. Participation in a MSWM program did appear to have a positive effect on physical activity postoperatively. CONCLUSION: MSWM does not appear to confer additional benefit as compared to the standard preoperative bariatric surgery protocol in terms of weight loss and most behavioral outcomes after LAGB in our patient population.
