Finding the place for nutrition in healthcare education and practice

Background: Malnutrition continues to impact healthcare outcomes, quality of life and costs to healthcare systems. The implementation of nutrition care in healthcare practice may improve health outcomes for patients and the community. This paper describes the iterative development and implementation of nutrition medical education resources for doctors and healthcare professionals in England. These resources are part of the Nutrition Education Policy for Healthcare Practice initiative. Method: Action research methodology was employed to develop and implement nutrition education workshops for medical students and doctors. The workshop was developed iteratively by an interdisciplinary project team, and the content was initially based on the General Medical Council outcomes for graduates. It was evaluated using quantitative evaluation tools and informal qualitative feedback captured from attendees using tools provided by the host organisations and developed by the roadshow team. Results: A total of 6 nutrition education workshops were delivered to 169 participants. This simple educational package demonstrated potential for delivery in different healthcare settings; however, formal feedback was difficult to obtain. Evaluation results indicate that workshops were better received when delivered by doctors known to the participants and included local context and examples. Reported barriers to the workshops included difficulty for participants in finding the time to attend, beliefs that peers gave a low priority to nutrition and uncertainty about professional roles in the delivery of nutrition care. Conclusion: A key outcome of this project was the development of resources for nutrition training of doctors, adapted to local needs. However, relatively low attendance and multiple barriers faced in the delivery of these workshops highlight that there is no ideal ‘place’ for nutrition training in current healthcare teaching. Interprofessional education, through relevant clinical scenarios may increase awareness of the importance of nutrition in healthcare, support the alignment of health professional roles and improve subsequent knowledge and skills

Time for nutrition in medical education.

AIM: To synthesise a selection of UK medical students' and doctors' views surrounding nutrition in medical education and practice. METHODS: Information was gathered from surveys of medical students and doctors identified between 2015 and 2018 and an evaluation of nutrition teaching in a single UK medical school. Comparative analysis of the findings was undertaken to answer three questions: the perceived importance of nutrition in medical education and practice, adequacy of nutrition training, and confidence in current nutrition knowledge and skills. RESULTS: We pooled five heterogeneous sources of information, representing 853 participants. Most agreed on the importance of nutrition in health (>90%) and in a doctor's role in nutritional care (>95%). However, there was less desire for more nutrition education in doctors (85%) and in medical students (68%). Most felt their nutrition training was inadequate, with >70% reporting less than 2 hours. There was a preference for face-to-face rather than online training. At one medical school, nutrition was included in only one module, but this increased to eight modules following an increased nutrition focus. When medical students were asked about confidence in their nutrition knowledge and on advising patients, there was an even split between agree and disagree (p=0.869 and p=0.167, respectively), yet few were confident in the UK dietary guidelines. Only 26% of doctors were confident in their nutrition knowledge and 74% gave nutritional advice less than once a month, citing lack of knowledge (75%), time (64%) and confidence (62%) as the main barriers. There was some recognition of the importance of a collaborative approach, yet 28% of doctors preferred to get specialist advice rather than address nutrition themselves. CONCLUSION: There is a desire and a need for more nutrition within medical education, as well as a need for greater clarity of a doctor's role in nutritional care and when to refer for specialist advice. Despite potential selection bias and limitations in the sampling frame, this synthesis provides a multifaceted snapshot via a large number of insights from different levels of training through medical students to doctors from which further research can be developed

Addressing nutritional gaps and suggesting a practical framework to reduce the risk of malnutrition and improve nutrition security in santhal tribal communities in India

Background The double burden of malnutrition is a growing problem, which is disproportionately represented across the Indian population, with undernutrition dominating rural areas. This study aimed to identify nutritional gaps in traditional recipes of Santhal tribes, create a recipe book to address deficiencies and support diet diversity. Methods Food Frequency Questionnaires (FFQ) were conducted to analyse dietary patterns of Santhal communities. Recipes were collected from five villages and shortlisted into 37 dishes based on availability, acceptability and popularity. Commonly consumed templates were based on FFQ findings and individual dishes. Nutritics software was used to identify nutritional gaps. In total, 24 recommended templates, were created to satisfy adequate intake of nutrients. Mann-Whitney and unpaired t-test were performed and findings were presented as mean (standard deviation(SD)) and median (25th–75th percentile). Results Less than one-fifth of consumed templates met energy requirements, 27% met protein recommendations, and 4% met requirements for fibre, total fat, monounsaturated and polyunsaturated fat. Other nutrients of concern included vitamins B12, B9, iodine, calcium and iron. Recommended templates significantly increased energy (Consumed (C): 996.0kcal(930-1090); Recommended (R): 1183.0kcal(1094-1341); p<0.0001), protein (C: 25.0g(8.4); R: 40.5g(33.2-52.3); p<0.0001), total fat (C: 7.4g(6.1-8.8); R: 17.2g(14.1-22.9); p<0.0001) and fibre (C: 5.0g(4.0-6.5); R: 8.2g(5.8-11.7); p=0.0013) compared to consumed templates. Additionally, calcium (C: 108.5mg(36.0-302.5); R: 245.5mg(152.3-528.3); p=0.0121), iron (C: 5.3mg(2.1-8.2); R: 10.7mg(8.2-13.2); p=0.0002), vitamin B6 (C: 0.4mg(0.3-0.7); R: 1.1mg(0.6-1.6); p=0.0001), B9 (C: 54.5ug(36.3-172.8); R: 252ug(179.4); p=0.0026) and B12 (C: 0ug(0-0); R: 1.0ug(0-2.1); p=0.0001) were also significantly increased. Conclusion This study provides a novel insight on the nutritional adequacy of indigenous Santhal recipes and highlights the need to enhance the nutrition status of these communities. Concerted efforts should be made to increase communication for nutritional advocacy, both nationally and internationally. Future research should evaluate the acceptability, practicality, and uptake of this recipe book in addressing malnutrition in rural communities

Norm violations and punishments across human societies

Punishments for norm violations are hypothesized to be a crucial component of the maintenance of cooperation in humans but are rarely studied from a comparative perspective. We investigated the degree to which punishment systems were correlated with socioecology and cultural history. We took data from the Standard Cross-Cultural Sample database and coded ethnographic documents from a sample of 131 largely nonindustrial societies. We recorded whether punishment for norm violations concerned adultery, religion, food, rape, or war cowardice and whether sanctions were reputational, physical, material, or execution. We used Bayesian phylogenetic regression modeling to test for culture-level covariation. We found little evidence of phylogenetic signals in evidence for punishment types, suggesting punishment systems change relatively quickly over cultural evolutionary history. We found evidence that reputational punishment was associated with egalitarianism and the absence of food storage; material punishment was associated with the presence of food storage; physical punishment was moderately associated with greater dependence on hunting; and execution punishment was moderately associated with social stratification. Taken together, our results suggest that the role and kind of punishment vary both by the severity of the norm violation, but also by the specific socio-economic system of the society

HIV Drugs Inhibit Transfer of Plasmids Carrying Extended-Spectrum β-Lactamase and Carbapenemase Genes

More and more bacterial infections are becoming resistant to antibiotics. This has made treatment of many infections very difficult. One of the reasons this is such a large problem is that bacteria are able to share their genetic material with other bacteria, and these shared genes often include resistance to a variety of antibiotics, including some of our drugs of last resort. We are addressing this problem by using a fluorescence-based system to search for drugs that will stop bacteria from sharing resistance genes. We uncovered a new role for two drugs used to treat HIV and show that they are able to prevent the sharing of two different types of resistance genes in two unique bacterial strains. This work lays the foundation for future work to reduce the prevalence of resistant infections.Antimicrobial-resistant (AMR) infections pose a serious risk to human and animal health. A major factor contributing to this global crisis is the sharing of resistance genes between different bacteria via plasmids. The WHO lists Enterobacteriaceae, such as Escherichia coli and Klebsiella pneumoniae, producing extended-spectrum β-lactamases (ESBL) and carbapenemases as “critical” priorities for new drug development. These resistance genes are most often shared via plasmid transfer. However, finding methods to prevent resistance gene sharing has been hampered by the lack of screening systems for medium-/high-throughput approaches. Here, we have used an ESBL-producing plasmid, pCT, and a carbapenemase-producing plasmid, pKpQIL, in two different Gram-negative bacteria, E. coli and K. pneumoniae. Using these critical resistance-pathogen combinations, we developed an assay using fluorescent proteins, flow cytometry, and confocal microscopy to assess plasmid transmission inhibition within bacterial populations in a medium-throughput manner. Three compounds with some reports of antiplasmid properties were tested; chlorpromazine reduced transmission of both plasmids and linoleic acid reduced transmission of pCT. We screened the Prestwick library of over 1,200 FDA-approved drugs/compounds. From this, we found two nucleoside analogue drugs used to treat HIV, abacavir and azidothymidine (AZT), which reduced plasmid transmission (AZT, e.g., at 0.25 μg/ml reduced pCT transmission in E. coli by 83.3% and pKpQIL transmission in K. pneumoniae by 80.8% compared to untreated controls). Plasmid transmission was reduced by concentrations of the drugs which are below peak serum concentrations and are achievable in the gastrointestinal tract. These drugs could be used to decolonize humans, animals, or the environment from AMR plasmids

'Bhavishya Shakti: Empowering the Future': establishing and evaluating a pilot community mobile teaching kitchen as an innovative model, training marginalised women to become nutrition champions and culinary health educators in Kolkata, India.

BACKGROUND: Malnutrition is a global emergency, creating an overlapping burden on individual, public and economic health. The double burden of malnutrition affects approximately 2.3 billion adults worldwide. Following 3 years of capacity building work in Kolkata, with assistance of local volunteers and organisations, we established an empowering nutrition education model in the form of a 'mobile teaching kitchen (MTK)' with the aim of creating culinary health educators from lay slum-dwelling women. AIMS: To evaluate the piloting of a novel MTK nutrition education platform and its effects on the participants, alongside data collection feasibility. METHODS: Over 6 months, marginalised (RG Kar and Chetla slums) women underwent nutrition training using the MTK supported by dietitians, doctors and volunteers. Preintervention and postintervention assessments of knowledge, attitudes and practices (KAP), as well as anthropometric and clinical nutritional status of both the women and their children were recorded. The education was delivered by a 'See One, Do One, Teach One' approach with a final assessment of teaching delivery performed in the final session. RESULTS: Twelve women were trained in total, six from each slum. Statistically significant improvements were noted in sections of KAP, with improvements in nutrition knowledge (+4.8) and practices (+0.8). In addition, statistically significant positive changes were seen in 'understanding of healthy nutrition for their children' (p=0.02), 'sources of protein rich food' (p=0.02) and 'not skipping meals if a child is ill' (p≤0.001). CONCLUSION: The MTK as a public health intervention managed to educate, empower and upskill two groups of lay marginalised women into MTK Champions from the urban slums of Kolkata, India. Improvements in their nutrition KAP demonstrate just some of the effects of this programme. By the provision of healthy meals and nutritional messages, the MTK Champions are key drivers nudging improvements in nutrition and health related awareness with a ripple effect across the communities that they serve. There is potential to upscale and adapt this programme to other settings, or developing into a microenterprise model, that can help future MTK Champions earn a stable income

Three-year review of a capacity building pilot for a sustainable regional network on food, nutrition and health systems education in India.

BACKGROUND: In Kolkata (India), there are high rates of malnourished children (45.9%) under the age of three, impacting growth, organ development, function, and cognition. Mothers have a major role to play during this crucial development stage, with research showing nutrition knowledge, attitudes and practices (KAP) of mothers are important determinants of childhood malnutrition. AIMS: To document 3 years of capacity building towards a sustainable nutrition education network in Kolkata, India, while assessing the ability to perform data collection in the form of needs assessments, impact assessments and capacity reviews. METHODS: Descriptive review and analysis of engagement and impact from 3 years of work by the NNEdPro Global Centre for Nutrition and Health, initiating locally led nutrition education interventions. Mapping to the Indian National Nutrition Strategy was also performed to review adherence to nationwide priorities surrounding nutrition and determine the wider application potential of the network. RESULTS: Two simultaneous projects were taken forward by a team of local healthcare professionals and student champions. Project 1-medical college workshops for medical student nutrition education with added focus on underserved populations, Project 2-preparation for a 'Mobile Teaching Kitchen' (MTK) in marginalised communities to empower local women as nutrition educators.Data collection methods used for analysing markers of impact and sustainability were semi-structured interviews of the community members, and KAP questionnaires to assess response to educational sessions. CONCLUSION: With local support it is possible to create and sustain fieldwork for an extended period with meaningful outputs and impact. This initiative demonstrates that it is possible to use healthcare professionals, students and volunteers with low-intensity training and a low-cost approach to produce action research with considerable impact and results in rapid, reliable and robust manner

AI is a viable alternative to high throughput screening: a 318-target study

: High throughput screening (HTS) is routinely used to identify bioactive small molecules. This requires physical compounds, which limits coverage of accessible chemical space. Computational approaches combined with vast on-demand chemical libraries can access far greater chemical space, provided that the predictive accuracy is sufficient to identify useful molecules. Through the largest and most diverse virtual HTS campaign reported to date, comprising 318 individual projects, we demonstrate that our AtomNet® convolutional neural network successfully finds novel hits across every major therapeutic area and protein class. We address historical limitations of computational screening by demonstrating success for target proteins without known binders, high-quality X-ray crystal structures, or manual cherry-picking of compounds. We show that the molecules selected by the AtomNet® model are novel drug-like scaffolds rather than minor modifications to known bioactive compounds. Our empirical results suggest that computational methods can substantially replace HTS as the first step of small-molecule drug discovery
