Preventing relapse to smoking with transcranial magnetic stimulation: Feasibility and potential efficacy.

Many smokers attempt to quit every year, but 90% relapse within 12 months. Converging evidence suggests relapse is associated with insufficient activation of the prefrontal cortex. Delay discounting rate reflects relative activity in brain regions associated with relapse. High-frequency repetitive transcranial magnetic stimulation (rTMS) of the left dorsolateral prefrontal cortex (LDLPFC) increases cortical excitability and reduces delay discounting rates, but little is known about feasibility, tolerability, and potential efficacy for smoking cessation. We hypothesized that 8 sessions of 20Hz rTMS of the LDLPFC combined with an evidence-based self-help intervention will demonstrate feasibility, tolerability, and potential efficacy in a limited double-blind randomized control trial. Smokers (n=29), abstinent for 24h, motivated to quit, and not using cessation medications, were randomized to active 20Hz rTMS at 110% of Motor Threshold or sham stimulation that replicated the look and sound of active stimulation. Stimulation site was located using the 6cm rule and neuro-navigation. Multiple clinical, feasibility, tolerability, and efficacy measures were examined. Active rTMS decreased delay discounting of $100 (F (1, 25.3694)=4.14, p=.05) and $1000 (F (1, 25.169)=8.42, p<.01), reduced the relative risk of relapse 3-fold (RR 0.29, CI 0.10-0.76, Likelihood ratio χ2 with 1 df=6.40, p=.01), increased abstinence rates (active 50% vs. sham 15.4%, Χ2 (df=1)=3.80, p=.05), and increased uptake of the self-help intervention. Clinical, feasibility, and tolerability assessments were favorable. Combining 20Hz rTMS of the LDLPFC with an evidence-based self-help intervention is feasible, well-tolerated, and demonstrates potential efficacy.

Position of the Academy of Nutrition and Dietetics: Interprofessional Education in Nutrition as an Essential Component of Medical Education.

It is the position of the Academy of Nutrition and Dietetics that registered dietitian nutritionists (RDNs) should play a significant role in educating medical students, residents, fellows, and physicians in practice. The more physicians learn about the effectiveness of nutrition for the prevention and treatment of noncommunicable diseases, the more likely they are to consult with RDNs and refer patients for medical nutrition therapy. The more interprofessional education that occurs between medical students, other health professional students, and RDNs, the more likely all health care professionals will understand and value the role of the RDN in improving the quality of care provided to patients. The training and experience of RDNs make them uniquely qualified for the role of educating medical students about nutrition as it relates to health and disease. This position paper provides RDNs with the tools and language to emphasize to medical educators, course directors, curriculum committees, medical school deans, residency and fellowship directors, physicians, and other health professionals in training and practice how ongoing nutrition counseling and management, conducted by an RDN, can benefit their patients. Specific teaching settings and examples for RDNs to take a leadership role (paid and unpaid positions) in ensuring that future physicians discuss nutrition, healthy lifestyle, and physical activity with their patients, consult with RDNs, and refer patients for medical nutrition therapy are presented. This position paper supports interprofessional education in nutrition as an essential component of medical education.

Implementation of a pilot primary care lifestyle change intervention for families of pre-school children: lessons learned.

OBJECTIVE: We used Glasgow's RE-AIM framework to evaluate the feasibility of a primary care-based intervention to decrease behaviors that place urban children at risk for obesity. METHODS: During preventive visits of 2-5-year olds between February 2006 and May 2007, parents completed a health behavior assessment. Primary care providers engaged parents in brief goal setting and referred them to a lifestyle counselor. Evaluation involved medical record review, interviews with staff and clinicians, and health behavior assessment via a pre- and post-intervention telephone survey. RESULTS: Families reached by the intervention did not differ from families who were not. The intervention was adopted by 14 of 17 clinicians. The health assessment was implemented in 32% of preventive visits (N=354). Of those, goal setting by physicians occurred in 59%, with 55% referred to the lifestyle counselor. We were unable to demonstrate effectiveness to change adult or child nutrition or physical activity, as complete data were available for only 34 families. CONCLUSION: Goal setting with referral for more intensive lifestyle counseling for obesity prevention in high risk families is feasible and acceptable in primary care. PRACTICE IMPLICATIONS: Patient educators can be integrated into primary care to achieve preventive care goals.

The bariatric surgery patient: a growing role for registered dietitians.

Between 1998 and 2004, the total number of bariatric procedures increased almost 10-fold, from 13,386 procedures in 1998 to 121,055 in 2004. Current estimates suggest the number of bariatric operations will exceed 220,000 in 2010. Bariatric surgery encompasses several surgical techniques classified as restrictive or malabsorptive, based on the main mechanism of weight loss. Clinical studies and meta-analyses show that bariatric surgery decreases morbidity and mortality when compared with nonsurgical treatments. A successful long-term outcome of bariatric surgery is dependent on the patient's commitment to a lifetime of dietary and lifestyle changes. The registered dietitian (RD) is an important member of the bariatric team and provides critical instructions to help patients adhere to the dietary changes consistent with surgery. Referencing current literature, this article outlines the indications, contraindications, and types of bariatric surgery. The role of the RD for preoperative and postoperative nutrition assessment and medical nutrition therapy is highlighted. Management of long-term nutrition issues is also reviewed. The current recommendations include a multivitamin/mineral supplement plus vitamin B-12, calcium, vitamin D-3, iron, and folic acid. Given the increasing prevalence of obesity and bariatric surgery procedures, caring for patients who have undergone surgery will be an expanding role for the RD. Close postoperative follow-up and careful monitoring will improve the odds for successful surgical outcomes, and RDs play a very important part in this process.

How can nutrition education contribute to competency-based resident evaluation?

The Curriculum Committee of the Nutrition Academic Award (NAA) has created a consensus document of knowledge, skills, and attitude learning objectives for medical nutrition education. To evaluate the impact of nutrition education in residency training, it is necessary to specify the goals and objectives of that education in terms of specific learner outcomes. To make the NAA objectives more user friendly for graduate medical education faculty, they must be translated into measurable competencies. The Accreditation Council for Graduate Medical Education has proposed a schema for organizing resident competencies. This article illustrates one way that the NAA curriculum objectives can be translated into specific competencies to demonstrate medical knowledge, patient care, practice-based learning, interpersonal and communication skills, professionalism, and systems-based practice.

Metabolic syndrome: time for action.

The constellation of dyslipidemia (hypertriglyceridemia and low levels of high-density lipoprotein cholesterol), elevated blood pressure, impaired glucose tolerance, and central obesity is identified now as metabolic syndrome, also called syndrome X. Soon, metabolic syndrome will overtake cigarette smoking as the number one risk factor for heart disease among the U.S. population. The National Cholesterol Education Program-Adult Treatment Panel III has identified metabolic syndrome as an indication for vigorous lifestyle intervention. Effective interventions include diet, exercise, and judicious use of pharmacologic agents to address specific risk factors. Weight loss significantly improves all aspects of metabolic syndrome. Increasing physical activity and decreasing caloric intake by reducing portion sizes will improve metabolic syndrome abnormalities, even in the absence of weight loss. Specific dietary changes that are appropriate for addressing different aspects of the syndrome include reducing saturated fat intake to lower insulin resistance, reducing sodium intake to lower blood pressure, and reducing high-glycemic-index carbohydrate intake to lower triglyceride levels. A diet that includes more fruits, vegetables, whole grains, monounsaturated fats, and low-fat dairy products will benefit most patients with metabolic syndrome. Family physicians can be more effective in helping patients to change their lifestyle behaviors by assessing each patient for the presence of specific risk factors, clearly communicating these risk factors to patients, identifying appropriate interventions to address specific risks, and assisting patients in identifying barriers to behavior change.

Nutrition education in family practice residency programs.

BACKGROUND AND OBJECTIVES: Nutrition is a required part of family practice residency training. Unfortunately, little is known about the quality or effectiveness of this nutrition training. This study evaluated the current status of nutrition training in family practice residency training programs. METHODS: We surveyed 100 randomly selected US family practice residencies about their nutrition education curriculum. Surveys were sent by e-mail, mail, fax, or administered by phone to individuals identified as responsible for nutrition teaching. A response rate of 66% was obtained. RESULTS: Programs varied greatly in their emphasis on nutrition. Identified barriers were similar across most programs. The presence of at least a part-time faculty member dedicated to nutrition was correlated with perceived effectiveness of nutrition education efforts. CONCLUSIONS: If family physicians are to be prepared to inform their patients regarding nutrition and to make appropriate referrals, improvements in the nutrition curriculum offered in many family practice residency programs will be required. Readers can evaluate their program's nutrition education efforts and see how they compare to our sample. Specific recommendations for potential changes are included.
