Specific gut bacterial responses to natural diets of tropical birds

The composition of gut bacterial communities is strongly influenced by the host diet in many animal taxa. For birds, the effect of diet on the microbiomes has been documented through diet manipulation studies. However, for wild birds, most studies have drawn on literature-based information to decipher the dietary effects, thereby, overlooking individual variation in dietary intake. Here we examine how naturally consumed diets influence the composition of the crop and cloacal microbiomes of twenty-one tropical bird species, using visual and metabarcoding-based identification of consumed diets and bacterial 16S rRNA microbiome sequencing. We show that diet intakes vary markedly between individuals of the same species and that literature-based dietary guilds grossly underestimate intraspecific diet variability. Furthermore, despite an effect of literature-based dietary guild assignment of host taxa, the composition of natural diets does not align with crop and cloacal microbiome similarity. However, host-taxon specific gut bacterial lineages are positively correlated with specific diet items, indicating that certain microbes associate with different diet components in specific avian hosts. Consequently, microbiome composition is not congruent with the overall consumed diet composition of species, but specific components of a consumed diet lead to host-specific effects on gut bacterial taxa.

125Clinical & demographic determinants of self-reported diet program adherence in people living with multiple sclerosis

Background A range of diets have been recommended for people living with MS, ranging from low or no-meat Swank-inspired diets, to the modified Palaeolithic Wahls diet. While the clinical efficacy of these diets to modulate MS progression is uncertain, the popularity of these diets amongst people living with MS is manifest. Methods Data derived from the 5-year review of the HOLISM international cohort study. Self-reported adherence to diets were queried, ranging 1-5. Adherence was restricted to ≥ 12months adherence, and then dichotomised: those reporting 4-5/5 adherence defined 2nd-most adherent, 3-5/5 adherence defined 3rd-most adherent. Determinants of adherence were evaluated by log-binomial regression, adjusted for age, sex, socioeconomic status (SES), education, and fatigue. Due to low numbers, only the Overcoming MS (OMS), Swank and Wahls diets were quantitatively evaluated. Results 458/952 (48.1%) reported following MS-specific diets for ≥12months; 61.8% followed OMS, 12.7% Swank, 3.5% Wahls, 0.9% Ashton-Embry, 0.9% McDougal, 5.7% other. OMS adherence (2nd-most) was more common among males, higher SES, lower disability, less fatigue, and fewer comorbidities. Wahls adherence (2nd-most) was more common among participants with progressive MS or greater disability. Swank adherence (2nd-most) did not vary by any parameter. Analogous results were found using the 3rd-most adherent definition. Conclusions These results indicate that MS-specific diet adherence is common in this patient population, but uptake is highly heterogenous between demographic and clinical subgroups. Further study of diet uptake among MS patients is indicated, particularly as the efficacy of these diets in MS is yet uncertain. Key messages There is evidence for a marked tribalisation of diet adherence between the OMS, Swank, and Wahls diets, the former being more common among less clinically active RRMS participants and Wahls more common among more clinically active progressive participants.

The many flavours of STEAM education for an inclusive environment

<p>STEAM is often seen as the integration of an art form into the teaching of sciences. Although that is not necessarily wrong, it is a very limited view of the powerful tool that STEAM learning can be. Just like a pizza, STEAM education can have “many flavours” and each of these “flavours” can be focused on with different intensities.</p> <p>POLAR STAR is an Erasmus project that focuses on innovative educational methods. One of its pillars is an innovative STEAM methodology that focuses on delivering an engaging education for a diverse classroom. To make the methodology more understandable, the team has come up with an amusing exercise called “the pizza challenge”. It invites teachers to create a pizza. The aim is to reflect on the fact that even for a specific diet (for e.g., vegan), different people with choose different ingredients and flavours according to their likes and dislikes. Similarly, in a classroom, each student will have their likes and dislikes, their interests, their way of thinking and of working, turning them into unique “consumers”. With this parallel, teachers realize that it is important to offer different “flavours” to different students in a classroom.</p> <p>The POLAR STAR methodology offers teachers a variety of lesson planners, focusing on the different flavours of STEAM. It guides teachers into reflecting on their students and choosing one or more activity templates for a given lesson. These templates can focus on <strong>S</strong>TEAM (with special emphasis on a science-based activity), on ST<strong>E</strong>AM (with special emphasis on an engineering-based activity) and on STE<strong>A</strong>M (with special emphasis on an arts-based activity). By diversifying the way they deliver their lessons teachers will be reaching a wider diversity of students and providing them with more engaging, motivational and interactive activities.</p> <p>POLAR STAR integrates these methodologies in a diverse kit of activities provided for teachers and students, following the different activity templates, in the fields of Astronomy and Polar Science, as well as holistic interdisciplinary learning approach, based on the Big Ideas of Science.</p> <p>All teachers are welcome in the project and can find more information on the projects’ website: http://polar-star.ea.gr/. During this talk the STEAM methodology to deliver Astronomy and Polar Science interactive lessons will be presented.</p>

Ayurvedic management of Koshtashrita Kamala (Hepatocellular Jaundice) - A Case report

Kamala is a type of Liver disorder mentioned in our classics. It is caused by vitiation of pitta with the signs and symptoms like Haridra netra (yellow eyes), twak nakha (yellowish skin and nails) and Dourbalya (weakness), based on these clinical features, it can be well understood under the purview of Jaundice. The condition where yellowish discoloration of skin and sclera of the eyes due to high level of serum bilirubin is known as Jaundice. The pitta present in the body aggravates due to specific diet and life style, attains sthana samshraya in koshta due to kha vaigunya, further causes dagdhatwa of Rakta and Mamsa this condition is known as Koshtashirita Kamala. A case presented with Peeta Netrata, Peeta Varnyata Mutra, Aruchi, Agnimandhya etc was diagnosed as Koshtashrita Kamala it was intervened successfully with Shodhana and Shamana oushadi with proper pathya for a period of 11 days. The effect of treatment was assessed based on improvement in clinical signs and symptoms along with Liver Function Test. There was significant improvement in the condition by 60% thus Kamala can be well managed by Ayurvedic intervention.

NUTRITIONAL SUPPLEMENTS AND THEIR USE WEIGHTS AMONGST THE AMATEUR BODYBUILDERS

In bodybuilding, the physical training takes different aspects, in particular the relationship with a specific diet and a substantial contribution of nutritional supplements. The diet for amateur bodybuilders is usually poor, having a negative impact in achieving sportive performance, because the muscle strengthening is closely bounded to vitamins, proteins, carbs, minerals, etc. In this study we have tested the hypothesis according to which in bodybuilding, achieving a good physique and sportive performance is not possible without nutritional supplementation. The study revealed that the athletes manifest a great interest into diet, corroborated with a protein supplementation in different concentrations.

CONCEPT OF ’YAMDANSHTRA’ IN AYURVED AND RISE IN CASES OF COVID 19 PANDEMIC

Upon observation of the steep rise in Covid cases patients all over the world, it seems to be clear that along with conventional methods for prevention and cure of this unpredictable disease, something more requires employment. This paper proposes that the concept of ’Yamdanshtra’ (described in Sharangdhar Samhita)1/ ”Ritusandhi”(described in Charak Samhita)2 is a viable solution. A specific ’diet modification pattern’(Padanshik Tyag vidhi) is recommended for better immunity. Detailed graphical studies have been shown about rela- tionship of the number of cases of Covid and the periods of Yamdanshtra or Ritusandhi(cusp between two seasons) in Bharat and three more countries viz. USA,UK and Russia. It was concluded in the study that a positive relation between Covid cases and transition periods can be established. In countries other than Bharat, the rise in Covid cases was present but not significant. It is hypothesized that that may be because the seasons do not show much differ- ence in climatic conditions or in other parameters. For Bharat, the Padanshik Tyag3 method of diet modification during transition periods may work,while other countries may prefer taking a lighter diet during them.

P601 Are Inflammatory Bowel Disease patients’ expectations met by dietetic services?

Background Guidelines recommend that Inflammatory Bowel Disease (IBD) patients should have access to specialised dietitian support. Literature suggests that patients are often dissatisfied with their access to reliable nutrition information and dietitian services. Our aim was to assess whether New Zealand (NZ) dietetic services were meeting the expectations of patients. Methods In early 2020 an electronic survey to explore experience of dietetic services was disseminated to approximately 2000 patients (and parents) by Crohn’s and Colitis NZ and IBD health professionals. Quantitative responses were analysed via non-parametric methods and qualitative responses were analysed via inductive analysis. Results Responses were received from 407 IBD patients. Participants were asked if it ‘is useful for patients diagnosed with IBD to have access to a dietitian for nutrition advice?’ with 86% responding ‘Yes’ and 12% ‘Maybe’. Almost all (95%) patients had nutrition topics that they would like to discuss with a dietitian but only 52% had seen a dietitian and 45% had never been referred. Patients were interested in various nutrition topics (Table 1). Most (65%) would like access to a dietitian whenever a new nutrition issue arises. The most frequent nutrition advice received was to follow a specific diet, most commonly a low fermentable carbohydrate diet followed by a low residue diet, or general nutrition advice. Two-thirds (66%) of respondents found the dietitian advice at least moderately useful while 18% reported it was not at all useful. Patients who saw a dietitian in a private clinic were more likely to find the advice useful (p=0.0001), as were those who had received written advice (p<0.0001). Common themes in response to open-ended questions included: frustration at difficulty accessing dietetic services; desire for routine dietitian referral at diagnosis and ongoing access; the need for dietitians to have specialist knowledge of IBD; a perception that some medical staff believe nutrition is not relevant in IBD management. Conclusion Many patients have never been referred to a dietitian and a proportion of patients did not find dietitian advice useful. Dietitian advice appears to be on the topics most commonly of interest to patients. Access to dietetic services needs to improve and exploration is needed to elucidate why some aspects of services are not meeting patient expectations.

The use of the ketogenic diet in the treatment of psychiatric disorders

Introduction The ketogenic diet (KD) is a high-fat, low-carbohydrate, and moderate-protein diet that has shown benefit as a treatment in neurologic disorders and may serve as a therapeutic option in individuals with psychiatric disorders. Methods A search was conducted using EBSCOhost and PubMed databases for studies relating to ketogenic or low-carbohydrate diets and psychiatric disorders. Results A total of 32 experimental or observational studies were identified by initial search strategies, 14 of which met the criteria to be included in this analysis. Although specific diet formulations varied somewhat between studies, they all generally examined low-carbohydrate dietary intake with the goal of producing a ketotic state. The studies included in this review indicated the KD was beneficial in reducing symptoms associated with various psychiatric disorders. Discussion This review summarizes the available evidence regarding the efficacy of the ketogenic diet in psychiatric disease states. Data from the studies analyzed demonstrated a positive response in individuals who were able to remain on the diet, regardless of the disease state. However, there is a need for more data to clearly define the specific benefits the KD may provide.

Specific dietary practices in female athletes and their association with positive screening for disordered eating

Background To determine if following specific diets was associated with reporting behaviors that are consistent with disordered eating compared to non-diet-adherent athletes. We hypothesized that athletes adhering to specific diets were more likely to report disordered eating than those not following a diet. Methods One thousand female athletes (15–30 years) completed a comprehensive survey about athletic health and wellness. Athletes were asked to specify their diet and completed 3 eating disorder screening tools: the Brief Eating Disorder in Athletes Questionnaire, the Eating Disorder Screen for Primary Care, and self-reported current or past history of eating disorder or disordered eating. Descriptive statistics were calculated for all study measures and chi-squared tests assessed relationships between athletes’ dietary practices and their responses to eating disorder screening tools. Statistical significance was defined as p < 0.05. Results Two hundred thirty-four of 1000 female athletes reported adherence to specific diets. 69 of the 234 diet-adhering athletes (29.5%) were excluded due to medically-indicated dietary practices or vague dietary descriptions. Of the 165 diet-adherent athletes, 113 (68.5%) screened positively to ≥1 of the 3 eating disorder screening tools. Specifically, athletes practicing a low-carbohydrate diet were more likely to report disordered eating vs. athletes without dietary restrictions (80% vs. 41.8%; p < 0.0001). Conclusion Specific diet adherence in female athletes may be associated with reporting behaviors that are consistent with disordered eating. Health practitioners should consider further questioning of athletes reporting specific diet adherence in order to enhance nutritional knowledge and help treat and prevent eating disorders or disordered eating.
