Development of a case-based integrated nutrition curriculum for medical students

Evaluation of biochemical composition of hulled and hull-less genotypes of pumpkin seeds grown in subtropical India

Pumpkin seeds are one of the functional foods with most potential having myriad of uses, and functioning as both edible seeds and oilseeds. Nevertheless, their utilization is restricted to the presence of a thick seed coat (hull) which subjects them to the process of decortication, increasing the farmers' expense as well as limiting their utilization as oilseeds. Therefore, in the present study, characterization of the biochemical composition of the hulled (Punjab Chappan Kadoo-1 abbreviated as PCK-1) and hull-less (PAU Magaz Kadoo-1 abbreviated as PMK-1) genotype of pumpkin seeds was undertaken to assess the nutritional differences and their efficient application; PMK-1 is a new cultivar of pumpkin released by Punjab Agricultural University in 2018. Based on the characterization, the hulled genotype of pumpkin seeds was observed to possess higher content of total soluble proteins (79.62 mg/100 g), total free amino acids (3.48 g/100 g), moisture (6.74%), fibre content (21.1 g/100 g), antioxidant potential (26.15%), polyamines (19.2 mg/100 g), sterols (387.1 mg/100 g), and specific enzymatic activity whereas the hull-less genotype was observed to possess a higher amount of minerals (4.57 g/100 g), tocopherols (15.76 mg/100 g), and oil content (36%) respectively; most of the biochemical parameters do not differ from each other at a greater fold difference except for total free amino acids and fibre, which are nearly four times and three times higher in hulled seeds in comparison to the naked seeds respectively. The two genotypes of seeds do not compete, rather do complement each other in biochemical and nutritional composition.

How might enhanced interprofessional collaboration between primary care physicians and registered dietitian nutritionists impact clinical outcomes related to obesity and associated illnesses? A commentary

The unsettling worldwide prevalence of obesity and obesity-related illnesses seems to be well-understood. What seems to be lacking, however, is a strategy of how best to fix the issue. Meagre nutrition content in medical school curricula may contribute to limited primary care physician (PCP) knowledge of the role nutrition has in health ailments and the understanding of a registered dietitian nutritionist (RDN) scope of practice. In USA, RDN are health care practitioners specialised in nutrition and who are experts in treating obesity and obesity-related illnesses. An increased RDN involvement in patient care has been shown to promote improvements in nutrition-related clinical outcomes. Therefore, enhanced collaboration between PCP and RDN has the potential to ameliorate the obesity epidemic. Tactics to promote collaboration may include enhancing nutrition education in medical school and providing nutrition-focussed continuing education for practicing physicians. The seriousness of the obesity epidemic underscores the need for interprofessional collaboration between PCP and allied health professionals who are uniquely trained to address obesity and obesity-related illnesses.

The state of nutrition in medical education in the United States

Despite the significant impact diet has on health, there is minimal nutrition training for medical students. This review summarizes published nutrition learning experiences in US medical schools and makes recommendations accordingly. Of 902 articles, 29 met inclusion criteria, describing 30 learning experiences. Nutrition learning experiences were described as integrated curricula or courses (n = 10, 33%), sessions (n = 17, 57%), or electives (n = 3, 10%). There was heterogeneity in the teaching and assessment methods utilized. The most common was lecture (n = 21, 70%), often assessed through pre- and/or postsurveys (n = 19, 79%). Six studies (26%) provided experience outcomes through objective measures, such as exam or standardized patient experience scores, after the nutrition learning experience. This review revealed sparse and inconsistent data on nutrition learning experiences. However, based on the extant literature, medical schools should build formal nutrition objectives, identify faculty and physician leadership in nutrition education, utilize preexisting resources, and create nutrition learning experiences that can be applied to clinical practice.

Medical Student Attitudes on Nutrition Counseling After Implementation of a Novel Curricular Activity

Objective: The aim of this research was to determine the changes in medical student attitudes toward nutrition counseling after implementation of a novel curricular activity during a required third-year clerkship.Method: All third-year medical students completing their required family medicine clerkship were invited to participate in a voluntary survey composed of the Nutrition in Patient Care Survey (NIPS) and demographics before their required curricular clerkship activity consisting of two separate case-based modules focused on nutritional aspects of patient care. Students and faculty facilitators met via web platform at an assigned time to review and discuss questions. All students were invited to complete the postsurvey composed of only the NIPS.Results: Completion rate was 31% for both pre- and postsurveys. Students' intended specialty choice did not lead to a significant difference in scores on any of the five subscales on pre-intervention surveys. Almost half (43.9%) of the students who completed the surveys reported offering nutrition-related counseling despite lack of formal training. The Physician-Patient Relationship score went from 4.29 to 4.37 (p < 0.03) and the Physician Efficacy score went from 3.18 to 3.34 (p < 0.01). The was no significant difference identified pre- versus postintervention for the Clinical Behavior scales.Conclusions: The modules used in this pilot study resulted in positive changes in student attitudes toward counseling patients about nutrition. The inclusion of required case-based modules focused on nutrition is feasible and can positively impact student attitudes regarding their efficacy in counseling patients.

A scoping review of health professional curricula: Implications for developing integration in pharmacy

BACKGROUND

Integrated health professions curricula aim to produce graduates who are capable of meeting current and future healthcare needs. This is reflected in pharmacy education where integration is increasingly advocated by pharmacy regulators as the perceived optimal way of preparing students for registration as pharmacists. There is, however, no definition of integration. Integration can be described according to a model of horizontal, vertical or spiral integration. It can also be described by the themes used to integrate, such as a systems-based approach or by integrative teaching and learning approaches. The level of integration can also be described.

OBJECTIVE

This scoping review aimed to explore health professions education literature to inform the optimal design of integrated pharmacy curricula. This review asks: what is meant by integration in health professions curricula?

METHODS

The Arksey and O'Malley scoping review framework was utilised. Ovid MEDLINE, EMBASE, Scopus, Web of Science and ERIC were searched. Models of integration, themes for integration, integrative teaching and learning approaches, and level of integration were defined and supported data extraction.

RESULTS

There were 9696 records screened and of these 137 were included. The majority of studies (n = 88) described horizontal integration. Systems-based teaching (n = 56) was the most common theme reported. Various integrative teaching and learning approaches were described, including experiential (n = 43), case-based (n = 42) and problem-based (n = 38) learning. The majority of the curricula could be classified as levels 5-7 on Harden's ladder (n = 102). Perception outcomes were reported for 81 studies, and only 3 reported outcomes beyond perception. Reported outcomes were generally positive and included knowledge gains and increased motivation.

CONCLUSIONS

There is a need for integration to be explicitly defined by curriculum developers and researchers. Attention should be given to describing the model, theme, teaching and learning approach and level of integration. There remains a lack of evidence for integration.

Medical Nutrition Education, Training, and Competencies to Advance Guideline-Based Diet Counseling by Physicians: A Science Advisory From the American Heart Association

Growing scientific evidence of the benefits of heart-healthy dietary patterns and of the massive public health and economic burdens attributed to obesity and poor diet quality have triggered national calls to increase diet counseling in outpatients with atherosclerotic cardiovascular disease or risk factors. However, despite evidence that physicians are willing to undertake this task and are viewed as credible sources of diet information, they engage patients in diet counseling at less than desirable rates and cite insufficient knowledge and training as barriers. These data align with evidence of large and persistent gaps in medical nutrition education and training in the United States. Now, major reforms in undergraduate and graduate medical education designed to incorporate advances in the science of learning and to better prepare physicians for 21st century healthcare delivery are providing a new impetus and novel ways to expand medical nutrition education and training. This science advisory reviews gaps in undergraduate and graduate medical education in nutrition in the United States, summarizes reforms that support and facilitate more robust nutrition education and training, and outlines new opportunities for accomplishing this goal via multidimensional curricula, pedagogies, technologies, and competency-based assessments. Real-world examples of efforts to improve undergraduate and graduate medical education in nutrition by integrating formal learning with practical, experiential, inquiry-driven, interprofessional, and population health management activities are provided. The authors conclude that enhancing physician education and training in nutrition, as well as increasing collaborative nutrition care delivery by 21st century health systems, will reduce the health and economic burdens from atherosclerotic cardiovascular disease to a degree not previously realized.

Learner-Directed Nutrition Content for Medical Schools to Meet LCME Standards

Deficiencies in medical school nutrition education have been noted since the 1960s. Nutrition-related non-communicable diseases, including heart disease, stroke, cancer, diabetes, and obesity, are now the most common, costly, and preventable health problems in the US. Training medical students to assess diet and nutritional status and advise patients about a healthy diet, exercise, body weight, smoking, and alcohol consumption are critical to reducing chronic disease risk. Barriers to improving medical school nutrition content include lack of faculty preparation, limited curricular time, and the absence of funding. Several new LCME standards provide important impetus for incorporating nutrition into existing medical school curriculum as self-directed material. Fortunately, with advances in technology, electronic learning platforms, and web-based modules, nutrition can be integrated and assessed across all four years of medical school at minimal costs to medical schools. Medical educators have access to a self-study nutrition textbook, Medical Nutrition and Disease, Nutrition in Medicine© online modules, and the NHLBI Nutrition Curriculum Guide for Training Physicians. This paper outlines how learner-directed nutrition content can be used to meet several US and Canadian LCME accreditation standards. The health of the nation depends upon future physicians’ ability to help their patients make diet and lifestyle changes.

A novel nutrition medicine education model: the Boston University experience

Most deaths in the United States are preventable and related to nutrition. Although physicians are expected to counsel their patients about nutrition-related health conditions, a recent survey reported minimal improvements in nutrition medicine education in US medical schools in the past decade. Starting in 2006, we have developed an educational plan using a novel student-centered model of nutrition medicine education at Boston University School of Medicine that focuses on medical student-mentored extracurricular activities to develop, evaluate, and sustain nutrition medicine education. The medical school uses a team-based approach focusing on case-based learning in the classroom, practice-based learning in the clinical setting, extracurricular activities, and a virtual curriculum to improve medical students' knowledge, attitudes, and practice skills across their 4-y period of training. We have been using objectives from the NIH National Academy Awards guide and tools from the Association of American Medical Colleges to detect new areas of nutrition medicine taught at the medical school. Although we were only able to identify 20.5 h of teaching in the preclerkship years, we observed that most preclerkship nutrition medicine objectives were covered during the course of the 4-y teaching period, and extracurricular activities provided new opportunities for student leadership and partnership with other health professionals. These observations are very encouraging as new assessment tools are being developed. Future plans include further evaluation and dissemination of lessons learned using this model to improve public health wellness with support from academia, government, industry, and foundations.

Current perception of nutrition education in U.S. medical schools

Historically, physicians have perceived the quality of nutrition training during medical school as inadequate. A literature review suggests that this perception has not significantly changed since the 1950s. Many schools have worked to create clinical nutrition curricula for use during medical school. Interestingly, data suggest that medical students' perception of the importance of clinical nutrition can decrease during medical school. Recent data support the importance of targeted nutritional therapy to reduce morbidity and mortality, yet the number of physicians interested in nutrition appears to be declining, and fewer hours of nutrition training are occurring in medical school. One possible solution to improve both training and awareness of the problem is to implement a certification program for both students and preceptors modeled after the Cardiac Life Support training offered by the American Heart Association.

A Problem-Based Learning Approach to Incorporating Nutrition into the Medical Curriculum

Problem Based Learning (PBL) provides a unique opportunity for medical students to learn nutrition principles in the context of evidence-based clinical cases. At the University of Texas Medical School at Houston (UTMSH), PBL is a major component during the second year of the four year undergraduate medical curriculum. A recent review of forty-two clinical cases has shown that over half of the cases include nutrition-specific objectives related to diagnosis, therapy, prognosis, or disease prevention. Thus, these PBL cases provide students the opportunity to study a broad range of nutrition topics in a clinically relevant context. The students' nutrition knowledge is evaluated using clinically-oriented, multiple-choice questions. In order for students to develop fully their competency in clinical nutrition topics, they are also provided a foundation in basic nutrition principles. This report describes a comprehensive approach through a case-based curriculum to help prepare students in their pre-clinical years for the nutritional care of patients in their clerkships, residency, and as practicing physicians.

Medical nutrition: a comprehensive, school-wide curriculum review

BACKGROUND

A school-wide nutrition program was established in 1982 and a required medical nutrition course (MNC) was established in 1985 at the University of Nevada School of Medicine. Emphasis was placed on developing an integrated curriculum and on using innovative methods to incorporate nutrition into the existing curriculum.

OBJECTIVE

The objective of this review was to establish a baseline and make positive curricular changes to comply with the recommendations of the Liaison Committee on Medical Education for accreditation. The MNC and the nutrition curriculum were evaluated as part of this 3-y comprehensive, school-wide evaluation process.

DESIGN

The MNC was invited for review (December 2004) because of its position in the curriculum (first year), special content and methods, and relation to other courses. A review team, which consisted of the Assistant Dean for Medical Education (who chaired the team), a curriculum coordinator, faculty representatives, and a medical student, was appointed. The MNC coordinator prepared a review book that included the requested documentation. The initial 3-h review meeting culminated in a formal evaluation and recommendations. Follow-up meetings at 1 mo and 1 y were scheduled.

RESULTS

The review was a positive process that reaffirmed the uniqueness of the nutrition program at the University. It supported the MNC as an important part of the required curriculum. Recommendations included use of the Web, encouragement to identify new opportunities with interested faculty, and a structure to further integrate and align nutrition into existing courses.

CONCLUSIONS

A positive, proactive review process supports the importance of nutrition in the medical school curriculum and encourages further integration.

Lessons learned from nutrition curricular enhancements

The Nutrition Academic Award funded 21 US medical schools to develop, implement, evaluate, and disseminate nutrition curricula for medical students, residents, and physicians in practice over a 5-y period. This article summarizes some of the important lessons learned from this process and offers guidance and strategies for long-term success of nutrition curricular enhancements. Medical educators need to continue to develop, implement, evaluate, and disseminate nutrition curricula with and without funding. By using the lessons learned and the products developed by the Nutrition Academic Award schools, educators will be in a position to enhance their medical curriculum.

Translation of nutritional sciences into medical education: the Nutrition Academic Award Program

For the past 40 y the scientific community has decried the inadequacy of the training of physicians and other health professionals in the subject of human nutrition. In 1997 the National Heart, Lung, and Blood Institute developed the Nutrition Academic Award (NAA) Program, an initiative to improve nutrition training across a network of US medical schools. The purpose of this funding, which began in 1998, is to support the development and enhancement of nutrition curricula for medical students, residents, and practicing physicians to learn principles and practice skills in nutrition. The NAA recipients developed the Nutrition Curricular Guide for Training Physicians, a plan to incorporate clinical guidelines into physician practice skills, create educational and assessment practice tools, and evaluate curricula, materials, and teaching tools. Dissemination of NAA activities and materials will be facilitated by a national website, presentations and publications, and consultants and advisors from the NAA nutrition education programs. The NAA Program constitutes a major new effort to enhance nutrition knowledge and skills among health care providers and to effectively apply the science of human nutrition to clinical medicine. This article describes the purpose and aims of the NAA Program, the organizational structure of the network of recipients, a profile of the recipients and individual programs at 21 medical schools, the various strategies to overcome barriers in training physicians in human nutrition, and collaborative and dissemination efforts.
