The first-line approach for managing obesity typically involves dietary interventions. This systematic review aim to evaluate the current evidence on various nutritional management for obesity based on the literatures of the last 10 years. Methods: The study adhered to PRISMA 2020 standards, examining English literature from 2014 to 2024. It excluded editorials, reviews from the same journal, and submissions without a DOI. PubMed, SagePub, SpringerLink, and Google Scholar were utilized as literature sources. Result: Initially retrieving 360 articles from online databases (PubMed, SagePub, SpringerLink and Google Scholar) eight relevant papers were selected after three rounds of screening for full-text analysis. Conclusion: Different nutritional strategies offer distinct benefits for managing obesity, with Mediterranean, anti-inflammatory, and low-carbohydrate diets showing promise. The key lies in promoting adherence and maintaining weight loss through tailored, sustainable interventions.

Nutritional support for stroke patients: an overview of international data and Russian experience

According to current data, the annual absolute number of strokes and deaths from them increased significantly from 1990 to 2019. In 2019, 12.2 million strokes were registered, while the total number of people who suffered a stroke in the world exceeded 100 million, of whom 6.55 million died. Worldwide, stroke remains the second leading cause of death (11.6%) and the third leading cause of death and disability combined (5.7%). Stroke patients are at high risk of developing malnutrition: its incidence upon admission to the hospital is about 20%, and the overall prevalence of this condition varies widely — from 6.1 to 62%. Both the previous and the resulting malnutrition is the reason for a longer stay in the hospital, deterioration of functional parameters and an increase in mortality 3–6 months after the stroke. Thus, adequate nutritional support for stroke patients should be considered as an integral component of their treatment and rehabilitation. This literature review is intended to summarize the foreign and Russian experience of nutritional support in stroke patients in order to develop an optimal algorithm of actions in the implementation of clinical nutrition in stroke patients and the use of the most effective dietary strategies that improve the prognosis, functional state and quality of life of this category of patients.

Mapping the Past Two Decades of Nutrition and Food Security in Iran: A Co-Word Network Analysis

Background: Food security in communities can prevent health complications, so investigators have made efforts to find its related factors through various fields. This study aims to draw a road map for nutrition and food security research in Iran. Methods: Web of Science, PubMed, Scopus, Embase, and Islamic World Citation Center were searched for eligible publications in nutrition and food security related to Iran for the two decades from 2001 to 2020. Content analysis was done by a co-word network technique using VOSviewer software. Results: Finally, 28,995 scientific publications among 50,444 search results were eligible to include in this study. The research map was drawn using 403,262 keywords obtained from the title and abstract of the papers. A 23.53% growth rate of publications was seen. Iranian articles were mainly published in scientific journals under 10 subject categories. The highly repeated keywords of "treatment", "plant", "age", "risk", and "consumption" were in publications. Moreover, the articles were categorized into thematic clusters of "environmental and climate change", "health ", "food industry and food safety", and "agriculture and water resources management" which were related to nutrition and food security. An increasing trend was observed in the number of publications during the past two decades in Iran. Conclusion: The relation of clinical nutrition, malnutrition, diet, and in recent years, food production and climate change with food security have been extensively studied by Iranian researchers. However, they have neglected studies on public health and policy in food and nutrition security, which reveals their dominant clinical or agricultural approach.

The role of child nutrition counselling, gender dynamics, and intra-household feeding decision-making on child dietary diversity in semi-arid northern Ghana

Every child has the right to proper nutrition. As such, child nutrition counselling is recommended to improve child dietary diversity and reduce malnutrition. However, there is limited empirical evidence on how child nutrition counselling, gender dynamics, and intra-household feeding decisions play a role and translate to child dietary diversity in rural contexts. Informed by theoretical conceptions from Health Belief Model (HBM) and Gender and Development (GAD) framework, we analyzed cross-sectional data from 517 smallholder households in Ghana's semi-arid Upper West Region to investigate the relationship between child nutrition counselling, gender dynamics, intra-household feeding decision-making, and their impact on child dietary diversity. Results from ordered logistic regression show that households that received child nutrition counselling reported higher child dietary diversity. Joint intra-household feeding decisions were associated with higher child dietary diversity. Households with good self-rated childcare, engaged in home gardening, and higher wealth, as well as those in the Waala ethnic group, were more likely to have high child dietary diversity. A decrease in household head age was linked to increased high child dietary diversity. On the other hand, female-headed households, Brifo ethnic groups, and those in the Wa East and Wa West districts were less likely to experience high child dietary diversity. Implementing interventions and policies prioritizing nutrition education in the Upper West Region and similar sub-Saharan African contexts is recommended. Strategies like scaling up child nutrition counselling, food demonstrations, mother-to-mother support nutrition outreach, and mobile nutrition clinics can empower women and improve children's well-being.

Feasibility of a multifaceted nutrition-risk screening tool for mental health settings: the NutriMental screener.

People living with mental illness report a broad spectrum of nutrition risks, beyond malnutrition, but appropriate and adequately validated nutrition risk screening tools for mental health settings are lacking. This study aimed to develop a nutrition-risk screening tool, the NutriMental Screener, and to perform preliminary feasibility and validity testing. In an international, stakeholder engaging approach, a multifaceted nutrition-risk screening tool for mental health services was developed by means of workshops with international stakeholders and two online surveys. Feasibility of the NutriMental screener was tested as part of a research study in Switzerland with 196 participants, evenly distributed across the three study groups (sixty-seven outpatients and sixty-five inpatients with psychotic or depressive disorders as well as sixty-four controls without mental illness). The NutriMental screener consists of ten items covering different nutritional issues that indicate the need for referral to a dietitian or clinical nutritionist. Almost all patients (94·7 %) reported at least one nutrition risk by means of the NutriMental screener. Prevalence for nutrition risks via NutriMental screener was higher in patients than in controls. Almost every second patient expressed a desire for nutritional support (44·7 %). After further validity testing is completed, there is the potential for the NutriMental Screener to replace malnutrition screening tools as routine screening in various mental health settings aiming to organise nutritional therapy prescriptions in a more targeted and efficient manner.

Improving the functional detection of sarcopenic obesity: prevalence and handgrip scoring in the OBESAR cohort.

The study objectives were: 1) to detect early signs of low muscle function and assess sarcopenic obesity (SO) prevalence in patients with obesity; and 2) to introduce a new online diagnostic tool for scoring handgrip strength (HGS), adjusted for age and sex. Patients from the OBESAR cohort (184 men and 499 women) were tested for body composition and functional testing (chair stand test or HGS based on the cutoffs from the European Society for Clinical Nutrition and Metabolism [ESPEN]/European Association for the Study of Obesity [EASO] or adjusted HGS [adHGS] based on reference values), and SO prevalence was calculated accordingly. Among the 683 patients (mean [SD], age 42.6 [12.8]years; BMI 44.4 [6.3] kg/m2), HGS averaged 25.6 (6.8) kg for women and 43.2 (10.4) kg for men. A total of 25.2% of patients had adHGS lower than the 10th percentile, but this was true for only 5.6% using ESPEN/EASO cutoffs of HGS. SO prevalence rates were different according to functional tests: 5.4%, 24.5%, and 3.2% for HGS, adHGS, and the chair stand test, respectively. Using adHGS through a scoring process considering age and sex may help to detect early signs of SO in a primary care setting in order to better prevent SO through a personalized approach in adults with obesity. A free online application, "GRip And Sarcopenia Prediction" (GRASP), is proposed to diagnose probable SO.

Unveiling the intrinsic role of malnutrition in patients with Crohn's disease undergoing major surgery using entropy balancing weighting analysis.

The negative role of malnutrition in patients with Crohn's disease is known; however, many coexisting disease-related factors could cause misinterpretation of the real culprit. This study aimed to describe the role of malnutrition using a novel methodology, entropy balancing. This was a retrospective analysis of consecutive patients undergoing elective major surgery for Crohn's disease, preoperatively screened following the European Society for Clinical Nutrition guidelines. Two-step entropy balancing was applied to the group of malnourished patients to obtain an equal cohort having a null or low risk of malnutrition. The first reweighting homogenised the cohorts for non-modifiable confounding factors. The second reweighting matched the two groups for modifiable nutritional factors, assuming successful treatment of malnutrition. The entropy balancing was evaluated using the d-value. Postoperative results are reported as mean difference or OR, with a 95 % CI. Of the 183 patients, 69 (37·7 %) were at moderate/high risk for malnutrition. The malnourished patients had lower BMI (d = 1·000), Hb (d = 0·715), serum albumin (d = 0·981), a higher lymphocyte count (d = 0·124), Charlson Comorbidity Index (d = 0·257), American Society of Anaesthesiologists (d = 0·327) and Harvey-Bradshaw scores (d = 0·696). Protective loop ileostomy was more frequently performed (d = 0·648) in the malnourished group. After the first reweighting, malnourished patients experienced a prolonged length of stay (mean difference = 1·9; 0·11, 3·71, days), higher overall complication rate (OR 4·42; 1·39, 13·97) and higher comprehensive complication index score (mean difference = 8·9; 2·2 15·7). After thesecond reweighting, the postoperative course of the two groups was comparable. Entropy balancing showed the independent role of preoperative malnutrition and the possible advantages obtainable from a pre-habilitation programme in Crohn's disease patients awaiting surgery.

Impact of MaNu dietary counselling on Oxidative Stress and Gestational Weight Gain during pregnancy

Abstract According to the WHO guidelines, to counteract the excessive weight gain during pregnancy and to mitigate the increase in oxidative stress (OS) which naturally increases during pregnancy, a healthy lifestyle and a correct diet are crucial as preventive measures to promote health. The MaNu project was conceived precisely to control these factors through dietary counselling. We expect that pregnant women who voluntarily undergo an educational program consisting of specific and accurate dietary advice will be able to emphasize weight control and contain the increase in OS. Our randomized controlled trial (RCT) has a parallel group design and takes place in the Obstetrics and Clinical Nutrition Departments of Michele and Pietro Ferrero Hospital (Verduno, north-western Italy), where physiological pregnant women are enrolled between 12-17 gestational weeks (GWs). The educational intervention takes place between 12-24 GWs. Dietary habits were collected with a questionnaire and urine samples were analysed to quantify the OS using 15-F2t-isoprostane, malondialdehyde and total antioxidant power. The descriptive analyses are based on paired t-tests. Preliminary analyses on 76 women who completed two out of three time points (T0 and T1) indicate that, of women who received the intervention, 35% experienced excessive weight gain (based on guidelines), compared to 39% shown by controls. Following the counselling, the 15-F2t-isoprostane decreased significantly (mean T0=5.1 ng/ml vs. mean T1=3.5 ng/ml, p = 0.02). Concerning nutrient intake, a statistically significant reduction in sugar consumption has been found in the intervention group (mean T0=92.2 g vs. mean T1=83.3 g, p = 0.03). Conversely, no correlations have been detected between OS and the main pro and anti-oxidant macronutrients. Although promising, our findings need further verification since the RCT is still ongoing, and it is imperative to attain the anticipated sample size before drawing any definitive conclusions. Key messages • Dietary counselling during pregnancy should be implemented as a preventive strategy used to counteract potential pregnancy complications and ensure the well-being of both the mother and the baby. • Healthy diet is essential to control the increase in oxidative stress levels during pregnancy and to prevent excessive weight gain, factors that can lead to the onset of pregnancy complications.

Perioperative Nutritional Support Case Study for a Patient Undergoing Gluteus Maximus Flap Transfer Surgery for Pressure Ulcer

Pressure ulcers are caused by prolonged pressure on local tissues, leading to continuous ischemia, hypoxia, and malnutrition, resulting in tissue necrosis. Patients with pressure ulcers often experience varying degrees of malnutrition due to gut flora imbalance and a hypercatabolic state. This paper documents the case of a patient with a sacral pressure ulcer admitted to the Department of Burn and Plastic Surgery of the Affiliated Hospital of Qinghai University on November 28, 2023. Clinical nutrition treatment began on the second day of admission, including dietary guidance and enteral nutrition intervention. The patient's nutritional status gradually improved, leading to a successful recovery. By reviewing the nutritional treatment process and clinical outcomes, this case study provides valuable insights into the nutritional management of pressure ulcer patients.

Community-Engaged Approaches for Improving the Inclusion of Diverse Communities in a Nutrition Clinical Trial

Background: Cardiometabolic disease (CMD) disproportionately affects African American/Black (AA) and Latino communities. CMD disparities are exacerbated by their underrepresentation in clinical trials for CMD treatments including nutritional interventions. The study aimed to (1) form a precision nutrition community consultant panel (PNCCP) representative of Latino and AA communities in Los Angeles to identify barriers and facilitators to recruitment and retention of diverse communities into nutrition clinical trials and (2) develop culturally informed strategies to improve trial diversity. Methods: A deliberative community engagement approach was used to form a PNCCP for the Nutrition for Precision Health (NPH) trial, part of the of the All of Us research initiative. The PNCCP included individuals that provide services for Latino and AA communities who met during 11 virtual sessions over 1 year. Discussion topics included enhancing recruitment and cultural acceptance of the NPH trial. We summarized CCP recommendations by theme using an inductive qualitative approach. Results: The PNCCP included 17 adults (35% AA, 47% Latino). Four thematic recommendations emerged: reducing structural barriers to recruitment, the need for recruitment materials to be culturally tailored and participant-centered, community-engaged trial recruitment, and making nutrition trial procedures inclusive and acceptable. We outlined the study response to feedback, including the constraints that limited implementation of suggestions. Conclusion: This study centers community voices regarding the recruitment and retention of AA and Latino communities into a nutrition clinical trial. It highlights the importance of community engagement early on in protocol development and maintaining flexibility to enhance inclusion of diverse communities in nutrition clinical trials.

Prevalence of Malnutrition and Micronutrient Deficiencies in Older Adults with Ulcerative Colitis.

The nutritional status and consequences of malnutrition among older adults with ulcerative colitis (UC) are not known. We conducted a retrospective study of patients 65years ≥ with Ulcerative colitis (UC). Malnutrition was defined using the European Society for Clinical Nutrition and Metabolism (ESPEN) definition. Eight micronutrients and nutrition-related outcomes were measured. The Saskatchewan Inflammatory Bowel Disease-Nutrition Risk Tool was utilized to identify patients at risk for malnutrition. Data were summarized using descriptive statistics. Characteristics of patients with and without malnutrition were compared using Chi-Square test or Fisher's exact tests (analysis of variance for age). Two-hundred and ninety patients with a mean age of 73.4years were included. 54% of patients had moderate-to-severe UC, with 52% receiving advanced therapy. Fifty-one patients (18%) met criteria for malnutrition, 17% were moderate-high risk for malnutrition, and 87% were low risk. Two-hundred and twenty patients (76%) had at least one micronutrient deficiency: 38% vitamin D, 43% iron, and 11% B12. Half of patients had osteoporosis or osteopenia (49%), however, only 39% of high-risk patients had undergone a DEXA scan. The majority of patients were not found to have malnutrition, however, the prevalence of micronutrient deficiencies among older adults with UC was high. This population is at particularly high risk for bone-related disease, yet a significant proportion of patients are not undergoing guideline-directed bone density testing. These findings illustrate the need for regular screening for malnutrition, micronutrient deficiency, and bone-related disease in older adults with UC.

Size-controlled interfacial crystallization of A-type resistant starch microparticles via acetone precipitation

Short-chain glucan (SCG) recrystallization has emerged as an effective approach for producing resistant starch microparticle (RSP), which hold promise in both food science and clinical nutrition. This study introduces a novel method utilizing Tween 80 (TW80) to mediate the interfacial recrystallization of SCG into A-type crystalline RSP (ARSP) through acetone precipitation. TW80 plays a crucial role by stabilizing water-in-oil microemulsion droplets within acetone-oil mixtures, facilitating the formation of uniform and spherical ARSP ranging in size from 0.2 μm to 2 μm. The surface characteristics of ARSP, including porosity and smoothness, are notably influenced by SCG concentration. As SCG concentration increases, the melting temperature of ARSP rises from 117 °C to 145 °C, accompanied by a decrease in average surface area from 12.07 to 8.35 m2/g, alongside an increase in crystallinity. Moreover, the in vitro digestion test revealed that the digestion rate of ARSP was decreased from 0.73 h−1 to 0.39 h−1 with increasing SCG concentration, while increasing the resistant starch (RS) content in ARSP from 48.6% to 70.5%. This enhancement offers a strategic approach for modulating the digestion rate of ARSP, presenting opportunities for tailored release profiles and improved stability in food science applications. These findings underscore the potential of ARSP as a functional ingredient with significant implications for nutritional and clinical settings.

Shaping the future: perspectives on the Integration of Artificial Intelligence in health profession education: a multi-country survey

BackgroundArtificial intelligence (AI) is transforming health profession education (HPE) through personalized learning technologies. HPE students must also learn about AI to understand its impact on healthcare delivery. We examined HPE students’ AI-related knowledge and attitudes, and perceived challenges in integrating AI in HPE.MethodsThis cross-sectional included medical, nursing, physiotherapy, and clinical nutrition students from four public universities in Jordan, the Kingdom of Saudi Arabia (KSA), the United Arab Emirates (UAE), and Egypt. Data were collected between February and October 2023 via an online survey that covered five main domains: benefits of AI in healthcare, negative impact on patient trust, negative impact on the future of healthcare professionals, inclusion of AI in HPE curricula, and challenges hindering integration of AI in HPE.ResultsOf 642 participants, 66.4% reported low AI knowledge levels. The UAE had the largest proportion of students with low knowledge (72.7%). The majority (54.4%) of participants had learned about AI outside their curriculum, mainly through social media (66%). Overall, 51.2% expressed positive attitudes toward AI, with Egypt showing the largest proportion of positive attitudes (59.1%). Although most participants viewed AI in healthcare positively (91%), significant variations were observed in other domains. The majority (77.6%) supported integrating AI in HPE, especially in Egypt (82.3%). A perceived negative impact of AI on patient trust was expressed by 43.5% of participants, particularly in Egypt (54.7%). Only 18.1% of participants were concerned about the impact of AI on future healthcare professionals, with the largest proportion from Egypt (33.0%). Some participants (34.4%) perceived AI integration as challenging, notably in the UAE (47.6%). Common barriers included lack of expert training (53%), awareness (50%), and interest in AI (41%).ConclusionThis study clarified key considerations when integrating AI in HPE. Enhancing students’ awareness and fostering innovation in an AI-driven medical landscape are crucial for effectively incorporating AI in HPE curricula.

Mapping the evolution and impact of ketogenic diet research on diabetes management: a comprehensive bibliometric analysis from 2005 to 2024.

The ketogenic diet (KD) has been explored for diabetes management; however, a quantitative synthesis of its specific effects on diabetes has not yet been conducted. This study aims to examine the current status and research hotspots of KD in diabetes management from 2005 to 2024, providing a reference for future research. We retrieved articles published between 2005 and 2024 from the Web of Science database and analyzed them using R software, VOSviewer, and CiteSpace. This study includes 432 relevant publications. From 2005 to 2024, the volume of literature in this field has shown a steady upward trend, with a notable increase from 2017 to 2021, and a slight decline observed from 2021 to 2023. The United States is the leading country in terms of the number of publications, followed by China, Australia, and Canada. The United States not only leads in publication volume but also maintains a broader international collaboration network. Nutrients and the American Journal of Clinical Nutrition are the most frequently published and cited journals. Current research hotspots primarily focus on the impact of KD on blood glucose control, insulin resistance, and lipid metabolism in diabetic patients. Mechanistic studies on KD in diabetes management concentrate on aspects such as the "regulation of genes by β-hydroxybutyrate," "anti-inflammatory effects," and "oxidative stress." The role of the gut microbiome is also emerging as an important research area. Currently, exploring the application of KD in managing different age groups and types of diabetes has become a significant research trend. As an emerging dietary intervention, KD is gradually attracting widespread attention from researchers around the world and is expected to become a major research focus in the future for diabetes management and control. This paper provides a systematic review and analysis of the current research status and hotspots of KD in diabetes management, offering important references and insights for future research in related fields.

Pharmacological and economical aspects of important species of Cordyceps sensu lato: A review.

Cordycepsis a well-known endo-parasitic fungus commonly used in traditional Chinese medicine for a long time. The demand for Cordyceps is increasing daily because it is commonly used as a nutritional food, medicine, and supplement owing to its natural source.

Integrating AI with medical industry chain data: enhancing clinical nutrition research through semantic knowledge graphs.

In clinical nutrition research, the medical industry chain generates a wealth of multidimensional spatial data across various formats, including text, images, and semi-structured tables. This data's inherent heterogeneity and diversity present significant challenges for processing and mining, which are further compounded by the data's diverse features, which are difficult to extract. To address these challenges, we propose an innovative integration of artificial intelligence (AI) with the medical industry chain data, focusing on constructing semantic knowledge graphs and extracting core features. These knowledge graphs are pivotal for efficiently acquiring insights from the vast and granular big data within the medical industry chain. Our study introduces the Clinical Feature Extraction Knowledge Mapping ( ) model, designed to augment the attributes of medical industry chain knowledge graphs through an entity extraction method grounded in syntactic dependency rules. The model is applied to real and large-scale datasets within the medical industry chain, demonstrating robust performance in relation extraction, data complementation, and feature extraction. It achieves superior results to several competitive baseline methods, highlighting its effectiveness in handling medical industry chain data complexities. By representing compact semantic knowledge in a structured knowledge graph, our model identifies knowledge gaps and enhances the decision-making process in clinical nutrition research.

Prognostic value of three clinical nutrition scoring system (NRI, PNI, and CONUT) in elderly patients with prostate cancer.

Most of patients with prostate cancer (PCa) are elderly and have a long course of disease. Preoperative assessment of the patient's clinical nutritional status facilitates early intervention and improves patient prognosis. We assessed the nutritional status of PCa patients utilizing the Nutritional Risk Index (NRI), Prognostic Nutritional Index (PNI), and Controlling Nutritional Status (CONUT) scoring systems. Survival comparisons between groups were conducted using Kaplan-Meier curve analysis and log-rank tests, while Cox proportional hazards regression analysis was employed to identify independent prognostic factors. Furthermore, we implemented bootstrap-based optimism correction methods to validate the scoring systems and applied decision curve analysis to evaluate the non-inferiority of these three clinical nutrition scoring systems relative to the conventional American Joint Committee on Cancer (AJCC) staging. In this study, malnutrition was diagnosed in 31.51% of the patients using the NRI, 13.02% using the PNI, and 88.28% using the CONUT score. After adjusting for confounders, normal nutritional status as defined by NRI and PNI emerged as an independent prognostic factor for prostate-specific antigen progression-free survival (PSA-PFS). However, nutritional status assessed by CONUT inaccurately predicted PSA-PFS. Normal nutritional status, as determined by all three scoring systems, was found to be an independent prognostic factor for progression-free survival (PFS). Following adjustments for optimistic estimates, the C-index for NRI in predicting both PSA-PFS and PFS remained the highest among the three scoring systems. The results of the DCA indicated that the C-index of all three scoring systems was higher than that of AJCC stage. NRI, PNI, and CONUT are convenient and clinically applicable scoring systems. A clinical malnutrition intervention may improve the prognosis of prostate cancer patients.
