Awareness and Self-Reported Knowledge and Training on Nutrition in Older People among Primary Care Practitioners.

OBJECTIVES: To assess the awareness and training of primary care physicians on nutrition in older patients. DESIGN: Observational, real-world data survey. SETTING: Primary Care. PARTICIPANTS: One hundred sixty-two physicians, generalists and specialists, working in primary care. MEASUREMENTS: Participants received an online questionnaire with 18 questions concerning the importance of nutrition, degree of knowledge, needs, and training in nutrition. The results were evaluated using univariate descriptive analysis, with a percentage for each chosen answer. Logistic regression models were used to evaluate if answers were related to training in nutrition and professional experience. RESULTS: 43.2% of participants reported that nutrition is very important in individuals over 65 years old, and 90% were aware of the importance of nutrition in healthy aging. Nutritional problems affect 30 to 50% of patients, according to 44.7% of participants. 89.2% agree about the need for nutritional assessment in older patients; however, the professionals believe they should be better prepared. Two out of three respondents consider the training received in nutrition during their undergraduate course or continuing medical education as deficient. Time of professional practice was mainly associated with conceptual facts, while continuing medical education did with practical issues, mainly the use of screening and diagnostic tools [FRAIL (OR: 3.16; 95%IC: 1.55-6.46), MNA-SF (OR: 6.455; 95%IC: 2.980-13.981) and SARC-F (OR: 3.063; 95%IC: 1.284-7.309)]. CONCLUSION: Although primary care professionals are aware of the importance of nutrition in older patients, there are still gaps in daily practice that could be improved by developing educational strategies.

Evolution of Food and Nutrition Policy: A Tasmanian Case Study from 1994 to 2023.

Food security is a concept with evolving definitions and meanings, shaped by contested knowledge and changing contexts. The way in which food security is understood by governments impacts how it is addressed in public policy. This research investigates the evolution of discourses and practices in Tasmanian food and nutrition policies from 1994 to 2023. Four foundational documents were analysed using qualitative document analysis, revealing persistent food insecurity issues over three decades. The analysis identified a duality in addressing the persistent policy challenges of nutrition-related health issues and food insecurity: the balancing act between advancing public health improvements and safeguarding Tasmania's economy. The research revealed that from 1994 to 2023, Tasmania's food and nutrition policies and strategies have been characterised by various transitions and tensions. Traditional approaches, predominantly emphasising food availability and, to a limited extent, access, have persisted for over thirty years. The transition towards a more contemporary approach to food security, incorporating dimensions of utilisation, stability, sustainability, and agency, has been markedly slow, indicating systemic inertia. This points to an opportunity for future policy evolution, to move towards a dynamic and comprehensive approach. Such an approach would move beyond the narrow focus of food availability to address the complex multi-dimensional nature of food security.

Global Leadership Initiative on Malnutrition (GLIM) for the diagnosis of malnutrition - a framework for consistent dietetic practice.

Malnutrition is an alarming and ongoing healthcare problem globally. Malnutrition has a negative impact on the individual patient, leading to poorer clinical outcomes and increased mortality, but also poses an economic burden on society. Proper identification and diagnostics are prerequisites for initiation of treatment. In 2019, the Global Leadership Initiative on Malnutrition, a consensus-based global framework to uniformly diagnose malnutrition across populations, healthcare settings, and countries was published. Identifying and treating malnutrition is an interdisciplinary team effort. Nonetheless, the nutrition and dietetics profession is specifically trained for diagnosing and treating nutrition(-related) conditions, and therefore has a key role in the interdisciplinary team in implementing the GLIM framework in clinical practice. For the nutrition and dietetics profession, GLIM offers a great opportunity for moving both the scientific and clinical knowledge of malnutrition management forward. While the GLIM framework has been extensively studied since its launch, various knowledge gaps still remain. For the nutrition and dietetics profession, these knowledge gaps mainly relate to the GLIM implementation process, to the role of GLIM in relation to the nutrition care process, and to treatment strategies for various nutrition-related conditions. In this opinion paper, we aimed to describe the rationale for implementing the GLIM framework in clinical dietetic practice, and propose a research agenda based on knowledge gaps regarding GLIM in relation to nutrition care from a dietetic point of view.

Cardiac and metabolic safety profile of antipsychotics in youths: A WHO safety database analysis.

A significant heterogeneity prevails in antipsychotics (APs) safety monitoring recommendations. Youths are deemed more vulnerable to cardiometabolic side effects. We aimed to assess age-dependent reporting of cardiac and metabolic disorders in youths, relying on the WHO safety database (VigiBase®). VigiBase® was queried for all reports of cardiac, glucose, lipid and nutritional disorders involving APs. Patients <18 years were classified as pediatric population. Disproportionality analyses relied on the Information Component (IC): the positivity of the lower end of its 95 % confidence interval was required to suspect a signal. We yielded 4,672 pediatric reports. In disproportionality analysis, nutritional disorders were leading in youths (IC 3.9 [3.9-4.0]). Among healthcare professionals' reports, stronger signals were detected in youths than in adults. Children had the greatest signal with nutritional disorders (IC 4.7 [4.6-4.8]). In adolescents, aripiprazole was ascribed to non-alcoholic steatohepatitis (NASH). Our findings, based on real-world data, support the hypothesis of a greater propensity for nutritional disorders in youths, despite limitations of pharmacovigilance studies. We suggest specific safety profiles, such as aripiprazole and NASH. Pending more answers from population-based studies, a careful anamnesis should seek for risk factors before AP initiation. A cautious monitoring is warranted to allow earlier identification of side effects.

Mast cell activation and nutritional disorders in patients with hypermobility.

PURPOSE OF REVIEW: Individuals with joint hypermobility disorders are increasingly referred to gastroenterology services for support with the investigation and management of gastrointestinal complaints. Individuals can present with a myriad of complex coexisting diagnoses, the inter-relationship of which is unclear. This review discusses the proposed association between hypermobile Ehlers-Danlos syndrome (hEDS) and hypermobility spectrum disorder (HSD) with disorders of mast cell activation and provides an overview of gastrointestinal symptoms and nutritional outcomes in this patient cohort. RECENT FINDINGS: It is unclear whether a true association between hEDS/HSD and mast cell activation disorders exists. There is a high prevalence of nonspecific gastrointestinal symptoms in individuals with hEDS/HSD and patients may be at risk of macro-nutrient and micro-nutrient deficiencies, although the current evidence base is limited. SUMMARY: We advocate a pragmatic approach to the investigation and management of gastrointestinal symptoms in patients with hEDS/HSD. This centres on excluding organic pathology, discussing the overlap with disorders of gut-brain interactions, trialling evidence-based therapies targeting individual symptoms, and supporting nutritional deficiencies where present via the least invasive approach. Engagement with a broad multidisciplinary team is also important to support the holistic needs of this patient cohort.

Trabajo a turnos y enfermedades no transmisibles relacionadas con la nutrición / Shift work and non-communicable diseases associated with nutrition

Objetivos: presentar las evidencias disponibles en cuanto al trabajo a turnos y las enfermedades no transmisibles relacionadas con la nutrición, e identificar qué efectos en la salud produce este tipo de trabajo, así como sintetizar las intervenciones más apropiadas para prevenir o tratar dichas patologías. Método: revisión narrativa. Se realizó una búsqueda en las bases de datos Pubmed, Web of Science y Scopus, con los descriptores MeSH: “Shift Work Schedule”, “Rotating Shift Work”, “Night shift work”, “Nutritional Status” y “Nutritional Disorders”. Se utilizaron filtros cronológicos (2018-2023) e idioma (inglés y español). Resultados: fueron seleccionados 29 artículos. Todos los trabajos coinciden en que existen alteraciones en la salud de los trabajadores que realizan trabajo a turnos, teniendo especial efecto en la dieta que seguían. Los principales efectos son el aumento del riesgo cardiovascular con mayores posibilidades de padecer síndrome metabólico, aumento del riesgo de desarrollar hipertensión arterial; peor control glicémico y del peso. En cuanto a intervenciones dietéticas, no se han encontrado trabajos de investigación que aborden esta cuestión. Se encontró una intervención de ocho semanas de ejercicio físico en un gimnasio presente en el lugar donde se trabaja. Conclusiones: el trabajo a turnos rotatorios se asocia con mayor riesgo cardiovascular, debido en gran parte a que estos trabajadores comen peor (mayor cantidad de energía ingerida, sin pautas fijas, abuso de grasas y azúcares, insuficiencia de fibra, etc.) y no realizan ejercicio de manera regular. Son necesarias intervenciones en el ámbito individual, organizacional y colectivo, así como profundizar en la investigación mediante estudios experimentales sobre la dieta. (AU)

Objectives: to present the evidence available regarding shift work and non-communicable diseases associated with nutrition, and to identify the impact on health caused by this type of work, as well as to summarize the most adequate interventions to prevent or treat said conditions. Method: a narrative review. A search was conducted in the Pubmed, Web of Science and Scopus databases, with the MeSH descriptors: “Shift Work Schedule”, “Rotating Shift Work”, “Night shift work”, “Nutritional Status” and “Nutritional Disorders”. The filters used were chronological (2018-2023) and language (English and Spanish). Results: twenty-nine (29) articles were selected. All of them coincided in the existence of alterations in the health of workers who conducted shift work, with particular impact on the diet they followed. The main effects were an increase in cardiovascular risk with higher likelihood of suffering metabolic syndrome, an increase in the risk of developing hypertension, and worse glycemic and weight control. In terms of diet interventions, no research articles addressing this matter were found. An intervention was found regarding eight weeks of physical exercise at a gym in the workplace. Conclusions: shift work was associated with higher cardiovascular risk, mostly due to the fact that these workers followed a worse diet (higher amount of energy ingested, without fixed patterns, abuse of fat and sugar, fibre deficiency, etc.) and did not exercise regularly. Interventions are required in the individual, organizational and collective settings, as well as to delve in research through experimental studies on diet. (AU)

Examining the influence of child nutritional disorders on early childhood development in Bangladesh: insights from the multiple indicator cluster survey.

OBJECTIVE: The objective of this study was to explore the relationship between various forms of child nutritional disorders and early childhood development in Bangladesh. DESIGN: We analysed data from the nationally representative cross-sectional 2019 Multiple Indicator Cluster Survey. Early childhood development was evaluated using the Early Childhood Development Index (ECDI), which comprised 10 yes-or-no questions across four domains: literacy-numeracy, physical well-being, socio-emotional development, and learning abilities. Nutritional disorders (e.g. stunting, wasting, and underweight) were measured based on the World Health Organization's height and weight guidelines. To investigate the relationships between child development and nutritional disorders, we used multilevel logistic regression models. SETTING: Bangladesh. PARTICIPANTS: Data of 9,455 children aged 3 and 4 years. RESULTS: Approximately 38 % of the children analysed experienced a nutritional disorder, with stunting being the most prevalent at 28·15 %. Overall, 25·27 % did not meet expected developmental progress measured by the ECDI. Stunted children were more likely to be off track developmentally, while those without any nutritional disorder were more likely to be on track. Socio-demographic factors, including age, sex, attendance in early childhood education programme, maternal education, maternal functional difficulties, region, and income, were identified as determinants of ECDI. CONCLUSIONS: Childhood nutrition and socio-demographic factors significantly affect multiple developmental domains and overall ECDI among children aged 3-4 years. Prioritising policies and programmes that improve nutrition and address these determinants are crucial for fostering optimal development in children.

Development of a Culinary Medicine Curriculum to Support Nutrition Knowledge for Gastroenterology Fellows and Faculty.

Gastroenterologists encounter many nutrition-related disorders in their practice, yet the nutritional needs of patients with chronic gastrointestinal (GI) and liver disease are largely unaddressed by treating physicians, due to suboptimal nutrition education. To address this gap, we developed and piloted a culinary medicine course for a GI fellowship training program. The objective of this study is to describe the development, implementation, and acceptability of the course. A registered dietitian, a chef instructor, and a gastroenterology clinical professor trained in culinary medicine developed the four-class tailored curriculum and delivered the classes remotely. Each class had a theme related to commonly encountered GI disorders and included hands-on meal preparation, a nutrition lecture, and a patient case study discussion. Post-course feedback surveys were disseminated. Twenty-three GI physicians enrolled in the course and the attendance rates in classes 1-4 were 83%, 65%, 61%, and 48%, respectively. Among 15 completed feedback surveys, 80% reported that the class contents were either moderately or extremely useful and all endorsed the curriculum for other gastroenterologists. Future studies of culinary medicine programs tailored to medical specialties should identify strategies to maintain engagement and assess the impact on nutrition knowledge, competencies, and translation of these new skills to clinical practice.

Scoping Review of Available Culinary Nutrition Interventions for People with Neurological Conditions.

People with neurological conditions may face barriers to meal preparation. Culinary nutrition interventions aim to facilitate the building of knowledge and skills for meal preparation. This scoping review aims to map the available evidence for culinary nutrition interventions for people with neurological conditions and evaluate the quality of these interventions based on program design, delivery and evaluation. After a systematic search of online databases (MEDLINE, CINAHL, Embase, Scopus and Proquest) and reference lists, a total of ten publications describing nine interventions were included. Most interventions were designed for people with stroke and/or Transient Ischemic Attack (n = 3) and Multiple Sclerosis (n = 3); others were for traumatic brain injury (n = 1), mild dementia (n = 1) and Parkinson's Disease (n = 1). Overall, the included culinary nutrition interventions had good program delivery (inclusion of motivational experiences, delivered by appropriate health providers) but needed improvements in program design (lack of consumer engagement and neurological symptom accommodations) and evaluation (lack of complete process, outcome and impact evaluations). In conclusion, the evidence base for culinary nutrition interventions for people with neurological conditions remains sparse. To bridge the gap between theory and practice, it is important to consider the following aspects in culinary nutrition intervention planning/improvement: (I) the involvement of consumers; (II) the accommodation/tailoring for post-condition effects; and (III) the coverage of all disease-specific culinary nutrition aspects.

The Connection between Knowledge and the Nutritional Behaviour of Parents and the Occurrence of Overweight and Obesity among Preschool Children-A Pilot Study.

The phenomenon of overweight and obesity constitutes a threat for health and children's lives at preschool age. Eating habits formed during this period seriously affect not only future dietary preferences but also the development of diet-related diseases. The purpose of the present study was the assessment of the relationship between the state of knowledge of children's nutrition and parents' eating behaviour and the prevalence of overweight and obesity in children aged 4-6 years. The study was conducted using 200 parent-child pairs. The behaviour and nutritional knowledge of parents was assessed using a questionnaire method. In contrast, anthropometric measurements were taken among the children. Nutritional disorders were noted in 46.5% of children of whom 39.0% struggled with overweight and 7.5% with obesity. The study showed that the children of parents with higher levels of nutritional knowledge were more likely to develop overweight and obesity. It also proved that irregularity of parental food intake predisposed the development of excessive body weight in children (p = 0.0049). Therefore, it is reasonable to undertake further investigation into factors implying the development of nutritional disorders among those youngest. Early recognition of dietary mistakes can contribute to their elimination at an early age.

Metabolic and Nutritional Issues after Lower Digestive Tract Surgery: The Important Role of the Dietitian in a Multidisciplinary Setting.

Many patients undergo small bowel and colon surgery for reasons related to malignancy, inflammatory bowel disease (IBD), mesenteric ischemia, and other benign conditions, including post-operative adhesions, hernias, trauma, volvulus, or diverticula. Some patients arrive in the operating theatre severely malnourished due to an underlying disease, while others develop complications (e.g., anastomotic leaks, abscesses, or strictures) that induce a systemic inflammatory response that can increase their energy and protein requirements. Finally, anatomical and functional changes resulting from surgery can affect either nutritional status due to malabsorption or nutritional support (NS) pathways. The dietitian providing NS to these patients needs to understand the pathophysiology underlying these sequelae and collaborate with other professionals, including surgeons, internists, nurses, and pharmacists. The aim of this review is to provide an overview of the nutritional and metabolic consequences of different types of lower gastrointestinal surgery and the role of the dietitian in providing comprehensive patient care. This article reviews the effects of small bowel resection on macronutrient and micronutrient absorption, the effects of colectomies (e.g., ileocolectomy, low anterior resection, abdominoperineal resection, and proctocolectomy) that require special dietary considerations, nutritional considerations specific to ostomized patients, and clinical practice guidelines for caregivers of patients who have undergone a surgery for local and systemic complications of IBD. Finally, we highlight the valuable contribution of the dietitian in the challenging management of short bowel syndrome and intestinal failure.

Evaluation of the nutrition care process documentation in the patients' records using the Diet-NCP-Audit: experience in a medium-sized multi-site Swiss hospital.

BACKGROUND: The nutrition care process (NCP) is a four-step systematic approach to guide dietitians in providing high-quality nutrition care. It fosters critical thinking and enhances the consistency of dietitians' documentation. Following international recommendations, University Training Hospital of Fribourg (HFR) implemented it in 2013. This study aimed to evaluate the quality of NCP documentation in electronic patient records (EPRs) and to determine the nutrition problems dietitians most often identified while documenting their actions. METHODS: The audit was performed on 92 EPRs using the Diet-NCP-Audit, which was translated into French for this study. RESULTS: The documentation quality was assessed as high in 62% of the EPRs, and nutrition diagnoses were mostly documented. In half of the EPRs, nutrition assessment (step 1 of the NCP) was inconsistent with nutrition diagnosis (step 2). Dietitians often used the same nutrition problems: out of the 73 nutrition problems defined in NCP terminology, only 4 (5%) represented 58% of the 189 problems identified in the EPR audit. CONCLUSION: EPRs were mostly assessed as high quality. However, the entire process requires improved consistency. The poorly documented link between the NCP steps and the restricted choices of nutrition problems dietitians identified should be addressed because they could reveal that dietitians have not fully adopted critical thinking, which the NCP stresses.

Advancing Nutrition and Dietetics Research in Global Food and Nutrition Security: A Roundtable Meeting Report.

Food and nutrition security remains a relevant issue globally, impacting nutritional status and other health outcomes. This is further complicated by various environmental factors that impact stable access to, availability of, and utilization of nutritious foods. Nutrition and dietetics practitioners play an important role in the identification and treatment of food and nutrition security and are also well positioned to advance research that can support food and nutrition security solutions. To address this important issue, the Academy of Nutrition and Dietetics' Council on Research convened a Global Food and Nutrition Security Research Task Force (Task Force). To leverage existing information and expertise in this area and identify the need for future evidence, the Task Force hosted a virtual roundtable with key internal and external stakeholders. This 2-day event included discussions on research gaps, potential entry points for nutrition and dietetics practitioners, and important equity considerations in the area of food and nutrition security research. The identified research gaps included the need for standardized terminology for consistent data collection, the need for validated screening and assessment tools that can be used across settings and also assess diet quality, additional translational and implementation science research, multi-sectoral and multi-pronged approaches, interdisciplinary collaboration with community partners, incorporation of research into policy development, and additional evidence on food systems approaches to target food and nutrition security. To more clearly identify the entry points for practitioners, five examples from various countries were included to identify food and nutrition security issues and how nutrition and dietetics practitioners can be involved in research to address food and nutrition security. The Task Force would like this information to inform a research agenda and be leveraged by the larger scientific community to drive future funding and research opportunities for food and nutrition professionals on this topic.

One Anastomosis Transit Bipartition (OATB): Rational and Mid-term Outcomes.

BACKGROUND: The "One-anastomosis transit bipartition" (OATB) is a promising emerging technique in the metabolic syndrome treatment. OBJECTIVE: To demonstrate the results achieved with OATB in the first 5 years after surgery. METHOD: Cross-sectional, retrospective study, with individuals undergoing primary OATB. Individuals included in the study were: ≥ 18 years, BMI ≥ 35 kg/m2; and excluded smoking habits, drug dependence, inflammatory bowel diseases. The data analyzed demographic, anthropometric, surgical, clinical, and nutritional. RESULTS: Sixty eight participants, 75% women, average age 45.5 years and BMI 41 kg/m2. Associated diseases: osteoarthritis (52.9%), hypertension (48.5%) and type 2 diabetes mellitus-T2DM (39.7%). All underwent laparoscopy, without conversions. Average operative time is 122.6 ± 31.7 min, and hospital stay is 2.2 ± 0.8 days. The common channel length 27 and 41 patients with 250 cm and 300 cm respectively. We registered no intraoperative complications, 2 (2.9%) early complications, and 14 (20.6%) late complications. In the first 6 months, 94.7% (250 cm) and 88.9% (300 cm) of the patients no longer used medication for T2DM, with no statistical difference between the two groups. The incidence of nutritional disorders at any time during follow-up: hypovitaminosis D (14.7%), folate hypovitaminosis (14.7%), elevated PTH (7.4%), hypoproteinemia (5.9%) and anemia (5.9%). We found no statistically significant difference between 250 and 300 cm common channel groups. CONCLUSION: We conclude that OATB is a safe and effective technique, demonstrating good control of T2DM and metabolic syndrome. There is a requirement to treat previous nutritional deficits. We need more long-term evidence and comparison to other surgical techniques.

Safety assessment of Brexpiprazole: Real-world adverse event analysis from the FAERS database.

OBJECTIVE: This study aims to analysis adverse drug events (ADE) related to Brexpiprazole from the third quarter of 2015 to the first quarter of 2023 from FAERS database. METHODS: The ADE data related to Brexpiprazole from 2015 Q3 to 2023 Q1 were collected. After standardizing the data, a variety of signal quantification techniques, including ROR, PRR, BCPNN, and MGPS were used for analysis. RESULTS: Among the 8559 ADE reports with Brexpiprazole as the primary suspected drug, 178 preferred terms (PT) of adverse reactions spanning 27 different system organ classes (SOC) were identified. Specifically, Metabolism and nutrition disorders and Reproductive system and breast disorders were unique adverse reactions to Brexpiprazole, with the latter not mentioned in the official drug label. Moreover, uncommon but significantly strong ADE signals, such as Egocentrism, Pharmacophobia, and Compulsions were observed. Notably, Tardive dyskinesia (n = 317, ROR 103.87, PRR 102.21, IC 6.21, EBGM 96.17) and Extrapyramidal disorder (n = 104, ROR 31.17, PRR 31.00, IC 4.57, EBGM 30.44) exhibited relatively high occurrence rates and signal strengths. Additionally, Lactation disorder (n = 6, ROR 48.09, PRR 48.07, IC 2.63, EBGM 46.71) and Breast discharge (n = 10, ROR 23.18, PRR 23.17, IC 2.94, EBGM 22.86) were observed, both presenting strong ADE signals. CONCLUSION: Brexpiprazole poses risks of various adverse reactions while providing therapeutic effects. In clinical applications, practitioners should closely monitor occurrences of Psychiatric disorders, Metabolism and nutrition disorders, Reproductive system and breast disorders, and other events.

Parenteral nutrition insecurity: ASPEN survey to assess the extent and severity of parenteral nutrition access and reimbursement issues.

BACKGROUND: Parenteral nutrition (PN) shortages and lack of qualified professional staff to manage PN impact safe, efficacious care and costs of PN. This American Society for Parenteral and Enteral Nutrition (ASPEN)-sponsored survey assessed the frequency and extent to which PN access affects PN delivery to patients. METHODS: Healthcare professionals involved with PN were surveyed. Questions were developed to characterize the respondent population and determine the extent and severity of PN access issues to components, devices, and healthcare professionals, as well as their effects on discharge and transfer issues. Reimbursement issues included cost, adequacy of therapy, and healthcare professional reimbursement. Burdens were types and frequency of errors, adverse events, and nutrition problems resulting from PN access issues. Impact on professionals and organizations was determined. RESULTS: Respondents (N = 350) worked in hospitals (75%) and home infusion (25%). Per day, clinicians cared for <15 patients receiving PN. All age populations were represented. Respondents reported shortages of macronutrients (72%, 233 of 324) and micronutrients (91%, 297 of 324). Issues with access to healthcare workers were observed. PN access issues contribute to increased costs of PN, and knowledge regarding the current rate of PN reimbursement is limited. Respondents (75%, 197 of 261) observed an error due to PN access issues. Adverse events (57%, 149 of 259) were observed leading to temporary or permanent harm (24%, 61 of 259) as well as near death (4%, 9 of 259) and death (1%, 2 of 259). Providers reported time away from other job responsibilities and workplace stress. CONCLUSION: PN access issues result in "PN insecurity" that negatively impacts patients and healthcare providers and leads to adverse events including death in patients receiving PN.
