Phosphatidylethanolamine N‐methyltransferase (PEMT) catalyzes phosphatidylcholine synthesis. PEMT knockout mice have fatty livers, and it is possible that, in humans, nonalcoholic fatty liver disease (NAFLD) might be associated with PEMT gene polymorphisms. DNA samples from 59 humans without fatty liver and from 28 humans with NAFLD were genotyped for a single nucleotide polymorphism in exon 8 of PEMT, which leads to a V175M substitution. V175M is a loss of function mutation, as determined by transiently transfecting McArdle‐RH7777 cells with constructs of wild‐type PEMT open reading frame or the V175M mutant. Met/Met at residue 175 (loss of function SNP) occurred in 67.9% of the NAFLD subjects and in only 40.7% of control subjects (P<0.03). For the first time we report that a polymorphism of the human PEMT gene (V175M) is associated with diminished activity and may confer susceptibility to NAFLD. Song, J., da Costa, K. A., Fischer, L.

Nutrition education in U.S. medical schools: latest update of a national survey.

Kelly M. Adams; Martin Kohlmeier; Steven H. Zeisel

Purpose To quantify the number of required hours of nutrition education at U.S. medical schools and the types of courses in which the instruction was offered, and to compare these results with results from previous surveys. Method The authors distributed to all 127 accredited U.S. medical schools (that were matriculating students at the time of this study) a two-page online survey devised by the Nutrition in Medicine Project at the University of North Carolina at Chapel Hill. From August 2008 through July 2009, the authors asked their contacts, most of whom were nutrition educators, to report the nutrition contact hours that were required for their medical students and whether those actual hours of nutrition education occurred in a designated nutrition course, within another course, or during clinical rotations. Results Respondents from 109 (86%) of the targeted medical schools completed some part of the survey. Most schools (103/109) required some form of nutrition education. Of the 105 schools answering questions about courses and contact hours, only 26 (25%) required a dedicated nutrition course; in 2004, 32 (30%) of 106 schools did. Overall, medical students received 19.6 contact hours of nutrition instruction during their medical school careers (range: 0–70 hours); the average in 2004 was 22.3 hours. Only 28 (27%) of the 105 schools met the minimum 25 required hours set by the National Academy of Sciences; in 2004, 40 (38%) of 104 schools did so. Conclusions The amount of nutrition education that medical students receive continues to be inadequate.

Bone Fracture History and Prospective Bone Fracture Risk of Hemodialysis Patients are Related to Apolipoprotein E Genotype

Martin Kohlmeier; Jörg Saupe; Klaus Schaefer; G. Asmus

Abstract. This investigation of 219 hemodialysis patients relates the history and prospective risk of bone fractures to apolipoprotein E (apoE) genotype. A greater percentage of the 41 patients with the E3/4 and E4/4 genotypes than of the 38 patients with the E2/3 and E2/2 genotypes had a history of bone fractures at the time of recruitment (44% versus 16%, P < 0.005). During the 4 years following recruitment, more of the patients with apoE genotypes E3/4 and E4/4 than with apoE genotypes E2/3 and E2/2 suffered bone fractures, but this difference was not statistically significant (17.1 versus 5.3%, P < 0.1). ApoE genotype appears to be an important genetic risk factor for bone fracture, possibly due to its previously reported influence on vitamin K concentrations in blood.

Background: The effects of isoflavone-enriched soy protein on human bone mineral content (mass) and density in healthy, menstruating young adult females have not been examined in a comparative prospective investigation. Peri- and post-menopausal women have been reported to show beneficial effects of isoflavones on bone measurements. Therefore, young women may also be able to improve their accrual of peak bone mineral content (BMC) and bone mineral density (BMD) during the early adult years of bone consolidation with an isoflavone-enriched diet. Objectives: In this controlled, double-blind intervention, we tested the hypothesis that an isoflavone-rich soy protein diet increases BMC and BMD in young adult females over a period of one year in comparison to a control group receiving soy protein that has isoflavones removed. Design: Young healthy women of any ethnic background, 21 to 25 years of age, were divided into two groups, placebo (n = 13) and supplement (n = 15). The soy protein supplement was enriched with isoflavones (∼90 mg of total isoflavones/day), whereas the control protein diet was isoflavone-deficient, even though it contained the same amount of soy protein and other ingredients as the isoflavone-rich diet. Dual-energy x-ray absorptiometric (DXA) measurements of BMC and BMD were made at baseline and at 6 and 12 months. DXA estimates of body composition, including fat mass and lean body mass, were generated from whole-body BMC measurements. BMI was calculated as weight (kg) over height (m) squared. Physical activity was assessed, and three-day dietary records were taken at entry (baseline) and at 6 and 12 months. Results: No changes in BMD after 12 months were found in either the isoflavone-treated (treatment) group or the isoflavone-deficient (control) group. Other variables also remained essentially constant over the 12-month period, including normal menstrual patterns in both the treatment and control groups. Conclusions: The isoflavone-rich soy preparation had no effects on BMC and BMD over a 12-month period in young healthy adult females with normal menses. An isoflavone-rich supplement appears to have little or no effect on bone in young adult women with normal ovarian function, at least over this 12-month study period.

Nutrition in Medicine Nutrition Education for Medical Students and Residents

Kelly M. Adams; Martin Kohlmeier; Margo Powell; Steven H. Zeisel

Proper nutrition plays a key role in disease prevention and treatment. Many patients understand this link and look to physicians for guidance diet and physical activity. Actual physician practice, however, is often inadequate in addressing the nutrition aspects of diseases such as cancer, obesity, and diabetes. Physicians do not feel comfortable, confident, or adequately prepared to provide nutrition counseling, which may be related to suboptimal knowledge of basic nutrition science facts and understanding of potential nutrition interventions. Historically, nutrition education has been underrepresented at many medical schools and residency programs. Our surveys over a decade show that most medical schools in the United States are still not ensuring adequate nutrition education, and they are not producing graduates with the nutrition competencies required in medical practice. Physicians, residents, and medical students clearly need more training in nutrition assessment and intervention. The Nutrition in Medicine (NIM) project, established to develop and distribute a core nutrition curriculum for medical students, offers a comprehensive online set of courses free of charge to medical schools. The NIM medical school curriculum is widely used in the United States and abroad. A new initiative, Nutrition Education for Practicing Physicians, offers an innovative online medical nutrition education program for residents and other physicians-in-training, but with targeted, practice-based educational units designed to be completed in 15 minutes or less. The NIM project is strengthening medical nutrition practice by providing a free, comprehensive, online nutrition curriculum with clinically relevant, evidence-based medical education for undergraduate and postgraduate learners.

Mitigation of alimentary lipemia by postprandial exercise-Phenomena and mechanisms

G. Schlierf; A. Dinsenbacher; H. Kather; Martin Kohlmeier; W. Haberbosch

The effects of a single bout of exercise at 40% of maximum aerobic capacity with regard to alimentary lipemia and postprandial lipoproteins was studied in a cross-over design in 12 young healthy male volunteers. In addition to lipids and lipoproteins, lipoprotein lipase, free glycerol, free fatty acids, plasma insulin, and C-peptide concentrations were quantitated. Postprandial exercise reduced alimentary lipemia by 34% while lipoprotein lipase activity rose by 42%. The postprandial fall of high-density lipoprotein (HDL)3 was abolished and the rise of HDL2 accentuated. Free glycerol and free fatty acid concentrations were higher following the meal plus exercise regimen compared to the meal alone. It is concluded that at least part of the chronic effect of exercise may come from additive effects such as observed from individual bouts of muscular activity.

Undergraduate medical education has undergone significant changes in development of new curricula, new pedagogies, and new forms of assessment since the Nutrition Academic Award was launched more than a decade ago. With an emphasis on a competency-based curriculum, integrated learning, longitudinal clinical experiences, and implementation of new technology, nutrition educators have an opportunity to introduce nutrition and diet behavior-related learning experiences across the continuum of medical education. Innovative learning opportunities include bridging personal health and nutrition to community, public, and global health concerns; integrating nutrition into lifestyle medicine training; and using nutrition as a model for teaching the continuum of care and promoting interprofessional team-based care. Faculty development and identification of leaders to serve as champions for nutrition education continue to be a challenge.

Residency and specialties training in nutrition: a call for action

Carine Lenders; Darwin Deen; Bruce R. Bistrian; Marilyn S. Edwards; Douglas L. Seidner; M. Molly McMahon; Martin Kohlmeier; Nancy F. Krebs

Despite evidence that nutrition interventions reduce morbidity and mortality, malnutrition, including obesity, remains highly prevalent in hospitals and plays a major role in nearly every major chronic disease that afflicts patients. Physicians recognize that they lack the education and training in medical nutrition needed to counsel their patients and to ensure continuity of nutrition care in collaboration with other health care professionals. Nutrition education and training in specialty and subspecialty areas are inadequate, physician nutrition specialists are not recognized by the American Board of Medical Specialties, and nutrition care coverage by third payers remains woefully limited. This article focuses on residency and fellowship education and training in the United States and provides recommendations for improving medical nutrition education and practice.

Biliary and plasma lipids and lipid-lowering chemotherapy Studies with clofibrate, fenofibrate and etofibrate in healthy volunteers

G. Schlierf; M. Chwat; E. Feuerborn; E. Wülfinghof; C.C. Heuck; Martin Kohlmeier; P. Oster; A. Stiehl

Abstract The effects of the lipid-lowering drugs clofibrate, etofibrate and fenofibrate on plasma lipids and lipoproteins and on biliary lipid composition were compared with placebo in double-blind cross-over studies in healthy young male volunteers. Within two weeks, plasma total cholesterol and LDL cholesterol levels fell on clofibrate administration (by means of 9 and 16%) and on feno-fibrate administration (by means of 17 and 16%). The “lithogenic index” — as a measure of biliary cholesterol saturation — rose significantly with clofibrate and etofibrate, but not with fenofibrate. These results suggest that drugs with similar effects on plasma lipids and lipoproteins may affect biliary lipid composition in different ways. The risk of cholelithiasis, therefore, must be evaluated separately for each drug in question, while the final answer can only come from long-term epidemiologic studies.

Getting nutrition education into medical schools: a computer-based approach

Karen Cooksey; Martin Kohlmeier; Claudia S. Plaisted; Kelly M. Adams; Steven H. Zeisel

Despite awareness of the importance of nutrition as part of medical students education, numerous barriers exist to incorporating nutrition education into the medical school curriculum. Chief among such barriers is that most medical schools do not have faculty trained specifically in nutrition. A curriculum is needed that can deliver comprehensive nutrition information that is consistent across medical schools. One way to deliver this information is to use computer-assisted instruction (CAI). To meet the different needs of medical schools and provide a consistent base of nutrition information, we developed a series of interactive, multimedia educational programs (Nutrition in Medicine) that teach the basic principles of nutritional science and apply those principles in a case-oriented approach. Curriculum content is derived from the American Society for Clinical Nutrition consensus guidelines. These modules offer the advantages of accessibility, self-paced study, interactivity, immediate feedback, and tracking of student performance. Modules are distributed free to all US medical schools. Preliminary data from surveys gathered by our team at the University of North Carolina at Chapel Hill indicate that 73 US medical schools use, or are planning to use, these modules; more schools are currently evaluating the programs. Successful implementation of CAI requires easy program access, faculty training, adequate technical support, and faculty commitment to the programs as a valuable resource. CAI fails when the program is just placed in the library and students are told to use it when they can find the time.
