A total of 216 （Exp. 1） and 360 （Exp. 2 ） barrows （ Yorkshire × Landrace× Duroc ） were allotted to one of six treatments （n =6）. The experimental diets were based on corn and soybean meal, and consisted of a high-CP diet that contained approximately 16% CP and 2.50 Mcal/kg of NE as well as five low-CP diets in which the CP level of the diet was reduced by approximately four percentage units but was supplemented with crystalline lysine, methionine, threonine, and tryptophan. The low CP diets provided 2.64, 2.58, 2.50, 2.42, or 2.36 Mcal/kg in Exp. 1 as well as 2.45, 2.40, 2.35, 2.30, or 2.25 Mcai/kg in Exp.2. In Exp. 1, a linear （P=0.03） increase in weight gain was observed with decreasing NE level while the ratio of gain to feed was unaffect- ed （P 〉 0.05） by NE level. There was a linear in-crease （P = 0.01 ） in the percentage of fat-free lean and a linear decrease （ P = 0.03 ） in the percentage of total fat with decreasing NE levels. In Exp. 2, a sig- nificant quadratic （ P = 0.03 ） effect of NE level was observed for weight gain. The ratio of gain to feed demonstrated a significant （P 〈0.01 ） quadratic effect with pigs fed 2.35 and 2.40 Mcal/kg of NE, Pigs fed the diet containing 2.40 Mcal/kg of NE had the lowest percentage of total fat （36. 95% ） and the highest percentage of fat-free lean （49.36%）. The overall results of these experiments indicate that feed- ing either a surplus or a deficiency of NE is detrimen- tal to both pig performance and carcass composition when low CP diets supplemented with CAA are fed. Our results indicate that when the CP content of the diet is reduced by four percentage units and the diet is properly supplemented with CAA, maximum per- formance and carcass quality will be obtained if the diet provides approximately 2.42 Mcal/kg of NE.展开更多

Nevertheless, very little is known about the neuroprotective potential of indicaxanthin. This study investigated the impact of indicaxanthin on neuronal damage and gut microbiota dysbiosis induced by a high-fat diet in mice. The mice were divided into three groups according to different diets: the negative control group was fed a standard diet;the high-fat diet group was fed a high-fat diet;and the high-fat diet + indicaxanthin group was fed a high-fat diet and received indicaxanthin orally(0.86 mg/kg per day) for 4 weeks. Brain apoptosis, redox status, inflammation, and the gut microbiota composition were compared among the different animal groups. The results demonstrated that indicaxanthin treatment reduced neuronal apoptosis by downregulating the expression of proapoptotic genes and increasing the expression of antiapoptotic genes. Indicaxanthin also markedly decreased the expression of neuroinflammatory proteins and genes and inhibited high-fat diet–induced neuronal oxidative stress by reducing reactive oxygen and nitrogen species, malondialdehyde, and nitric oxide levels. In addition, indicaxanthin treatment improved the microflora composition by increasing the abundance of healthy bacterial genera, known as producers of short-chain fatty acids(Lachnospiraceae, Alloprovetella, and Lactobacillus), and by reducing bacteria related to unhealthy profiles(Blautia, Faecalibaculum, Romboutsia and Bilophila). In conclusion, indicaxanthin has a positive effect on high-fat diet–induced neuronal damage and on the gut microbiota composition in obese mice.展开更多

The key parameters examined included resolution rates, treatment duration, and recurrence.RESULTSA comprehensive literature search yielded 13 studies that met the inclusion criteria, comprising 4 retrospectivecohort studies and 8 case studies. The incidence of CA following liver transplantation ranges from 0.6% to 4.7%.The onset varied, with a median time to diagnosis of 10 days after transplantation. A LFD with MCT supplementationwas used as the first-line therapy in 83.3% of the studies, with resolution rates ranging from 62.5% to100%. Octreotide therapy was utilized in 66.7% of the studies, primarily as a second-line therapy, with resolutionrates of 83.3% to 100%. Combination therapy showed a significantly higher resolution rate than did dietarymanagement alone (97.8% vs 78.9%, P = 0.02). The time to resolution was significantly shorter with octreotidecontainingregimens than with dietary management alone (median, 7 days vs 14 days;P = 0.03).CONCLUSIONA stepwise approach to CA management is recommended, initiating dietary interventions and escalating tooctreotide when necessary. Further research through well-designed randomized controlled trials is essential toestablish standardized treatment protocols for optimizing patient outcomes.展开更多

In recent decades, plant-based dietshave received increasing attention for their potential benefits for humans and theenvironment. However, a comprehensive overview of the development trends and researchhotspots of plant-based diets is still lacking. Therefore, this scientometric study aimed to fillthis critical research gap. Methods: English literature related to plant-based diets publishedfrom 2012 to 2023 in Science Citation Index Expanded (SCIE) of Web of Science CoreCollection was collected on August 16, 2023, using relevant key terms. R-bibliometrix,CiteSpace, and VOSviewer were used to analyze data and construct knowledge graphs.Results: Overall, 4135 publications (3127 articles and 1008 reviews) were included in thisstudy, showing an obvious upward trend in this field annually from 2012 to 2023, rangingfrom 70 to 921. The USA published the highest number of studies (n =1158) and was theleading research center in this field worldwide. Universities were the main researchinstitutions;particularly, Harvard T.H. Chan School of Public Health contributed to thelargest number of publications (n = 88) and had an active cooperation with otherinstitutions. Mcclements DJ contributed the most publications (n = 49) and ranked firstamong the scholars in plant-based diets. The most productive academic journal (n = 353)on plant-based diets was Nutrients, with an IF2022 of 5.9, while Foods and Frontiers in Nutritionwere the relatively active journals in this field in recent years. “Quality,” “milk,” “culturedmeat,” “plant protein,” “environmental impacts,” “functional properties,” “plant-based meatalternative,” “dietary change,” “vegan diet,” “plant-based beverage,” “gut microbiota,”“middle-income countries,” and “chronic kidney disease” were the main research hotspotsand frontiers in the field of plant-based diets. Conclusion: This study provides acomprehensive overview of global research on plant-based diets. Although research in thisfield has gained increasing attention in recent decades, cooperation among differentinstitutions and researchers should be significantly strengthened. Moreover, more studiesare needed to further assess the health and environmental impacts of plant-based diets.展开更多

This study aimed to evaluate the effectiveness of a workshop-based model for increasing dysphagia diet awareness among prosthodontists working with head and neck cancer patients. Methods: The study had a post-intervention design and included 10 maxillofacial prosthetic educators from eight countries who participated in a 120-minute workshop focused on theoretical and practical training in nutrition support for patients with dysphagia. Sessions were held in a specialized restaurant in Tokyo and included lectures, observation of Japanese cooking techniques, hands-on preparation of dysphagia-friendly foods, and cross-cultural comparisons. Knowledge, confidence, and practical application were assessed using a post-workshop questionnaire. Descriptive statistics and thematic analysis were used to evaluate outcomes. Results: Seven of the 10 prosthodontists completed the post-intervention questionnaire. All respondents reported overall satisfaction with the workshop. Session content was regarded as easy to understand by 57.14%, appropriate by 28.57%, and easy by 14.29%. Most respondents (85.71%) were “very satisfied” with the instructors’ explanations, and 100% were “very satisfied” with the workshop’s length and structure;71.42% felt they could apply the knowledge in clinical practice, while 28.58% anticipated challenges. The respondents appreciated the workshop’s focus on dysphagia, particularly in elderly patients, and valued the insights into Japanese dysphagia diets and culture. Conclusions: Workshops on nutrition provide an interactive platform for prosthodontists to enhance their knowledge and improve comprehensive patient care, highlighting the importance for prosthodontists to stay updated on developments in nutrition, particularly in dysphagia.展开更多

文摘Two experiments were conducted to in- vestigate the effects of net energy （NE） level on the performance and carcass traits of finishing pigs fed low crude protein （CP） diets supplemented with crystalline amino acids （CAA）. A total of 216 （Exp. 1） and 360 （Exp. 2 ） barrows （ Yorkshire × Landrace× Duroc ） were allotted to one of six treatments （n =6）. The experimental diets were based on corn and soybean meal, and consisted of a high-CP diet that contained approximately 16% CP and 2.50 Mcal/kg of NE as well as five low-CP diets in which the CP level of the diet was reduced by approximately four percentage units but was supplemented with crystalline lysine, methionine, threonine, and tryptophan. The low CP diets provided 2.64, 2.58, 2.50, 2.42, or 2.36 Mcal/kg in Exp. 1 as well as 2.45, 2.40, 2.35, 2.30, or 2.25 Mcai/kg in Exp.2. In Exp. 1, a linear （P=0.03） increase in weight gain was observed with decreasing NE level while the ratio of gain to feed was unaffect- ed （P 〉 0.05） by NE level. There was a linear in-crease （P = 0.01 ） in the percentage of fat-free lean and a linear decrease （ P = 0.03 ） in the percentage of total fat with decreasing NE levels. In Exp. 2, a sig- nificant quadratic （ P = 0.03 ） effect of NE level was observed for weight gain. The ratio of gain to feed demonstrated a significant （P 〈0.01 ） quadratic effect with pigs fed 2.35 and 2.40 Mcal/kg of NE, Pigs fed the diet containing 2.40 Mcal/kg of NE had the lowest percentage of total fat （36. 95% ） and the highest percentage of fat-free lean （49.36%）. The overall results of these experiments indicate that feed- ing either a surplus or a deficiency of NE is detrimen- tal to both pig performance and carcass composition when low CP diets supplemented with CAA are fed. Our results indicate that when the CP content of the diet is reduced by four percentage units and the diet is properly supplemented with CAA, maximum per- formance and carcass quality will be obtained if the diet provides approximately 2.42 Mcal/kg of NE.

文摘This review shows that relatively simple changes to diet and lifestyle can significantly,and rapidly,reduce the risks associated with coronavirus disease 2019(COVID-19)in terms of infection risk,severity of disease,and even disease-related mortality.A wide range of interventions including regular exercise,adequate sleep,plant-based diets,maintenance of healthy weight,dietary supplementation,and time in nature have each been shown to have beneficial effects for supporting more positive health outcomes with COVID-19,in addition to promoting better overall health.This paper brings together literature from these areas and presents the argument that non-pharmaceutical approaches should not be overlooked in our response to COVID-19.It is noted that,in several cases,interventions discussed result in risk reductions equivalent to,or even greater than,those associated with currently available vaccines.Where the balance of evidence suggests benefits,and the risk is minimal to none,it is suggested that communicating the power of individual actions to the public becomes morally imperative.Further,many lives could be saved,and many harms from the vaccine mandates avoided,if we were willing to embrace this lifestyle-centred approach in our efforts to deal with COVID-19.

文摘Vine tea is documented in ancient Chinese books as having the function of promoting blood circulation.However,its effects and mechanisms remain unclear.The aim of this study was to comprehensively investigate the protective potential and mechanisms of vine tea in high-fat diet rat through a combination of in vivo and in vitro experiments.The efficacy of vine tea was evaluated using a high-fat diet rat model and an oxidized low-density lipoprotein-treated cell model,with physiological and biochemical indicators measured in rat serum and cell supernatants.Transcriptomics was utilized to investigate alterations mRNA expression following the administration of dihydromyricetin in cell model.Metabolomics and 16S rRNA sequencing was employed to examine changes in metabolites in the serum and changes in gut microbiota of high-fat diet rats after administering vine tea extract.Vine tea extract and dihydromyricetin can reduce elevated levels of lipids,including total cholesterol and triglycerides,following modeling.Transcriptomic data indicate that dihydromyricetin exerts its effects by regulating ferroptosis signaling pathways.Metabolomic analysis demonstrates that the administration of vine tea extract influences the vitamin K cycle and glutathione,thereby alleviating the progression of ferroptosis.Additionally,16S rRNA sequencing reveals that vine tea extract increases Lactobacillaceae in the gut microbiota,which subsequently affects the levels of lysophosphatidylcholine,a major phospholipid component of oxidized low-density lipoprotein in serum.Our results indicate that vine tea can regulate ferroptosis signaling pathways and increase Lactobacillaceae in the gut microbiota,thereby exhibiting cardiovascular protective effects in high-fat diet rats.

文摘Krill oil is effective in reducing blood lipid levels,particularly in individuals with severe hyperlipidemia.However,poor water insolubility and stability limited its usage.This study investigated a method for encapsulating Antarctic krill oil using alginate(ALG)and gelatin(GLN)to enhance its stability and bioactivity.The encapsulation efficiency,functional group integrity,swelling rate,and lipid-lowering activity were assessed.Results indicated that the optimal encapsulation conditions were identified with an ALG:GLN ratio of 2:1(m/m),coagulation bath of 9%CaCl_(2),and a nozzle size of 750μm,resulting in 69.34%encapsulation efficiency.Fourier-transform infrared spectroscopy confirmed successful encapsulation.The ALG-GLN shell materials enriched astaxanthin in krill oil and protected it from harsh gastric conditions,enabling targeted intestinal release.In a high-fat diet-induced rat model,krill oil microcapsules significantly reduced triglycerides(TG),total cholesterol(TC),and low-density lipoprotein-cholesterol(LDL-C)levels while increasing high-density lipoprotein-cholesterol(HDL-C)levels compared to unencapsulated krill oil.Additionally,the microcapsules elevated nitric oxide(NO)levels,enhanced superoxide dismutase(SOD)activity,and reduced malondialdehyde(MDA)levels,liver and perirenal fat weight.Therefore,encapsulating Antarctic krill oil in alginate-gelatin hydrogel offers a promising strategy for managing hyperlipidemia and associated metabolic disorders.

文摘Indicaxanthin is a betalain that is abundant in Opuntia ficus-indica orange fruit and has antioxidative and anti-inflammatory effects. Nevertheless, very little is known about the neuroprotective potential of indicaxanthin. This study investigated the impact of indicaxanthin on neuronal damage and gut microbiota dysbiosis induced by a high-fat diet in mice. The mice were divided into three groups according to different diets: the negative control group was fed a standard diet;the high-fat diet group was fed a high-fat diet;and the high-fat diet + indicaxanthin group was fed a high-fat diet and received indicaxanthin orally(0.86 mg/kg per day) for 4 weeks. Brain apoptosis, redox status, inflammation, and the gut microbiota composition were compared among the different animal groups. The results demonstrated that indicaxanthin treatment reduced neuronal apoptosis by downregulating the expression of proapoptotic genes and increasing the expression of antiapoptotic genes. Indicaxanthin also markedly decreased the expression of neuroinflammatory proteins and genes and inhibited high-fat diet–induced neuronal oxidative stress by reducing reactive oxygen and nitrogen species, malondialdehyde, and nitric oxide levels. In addition, indicaxanthin treatment improved the microflora composition by increasing the abundance of healthy bacterial genera, known as producers of short-chain fatty acids(Lachnospiraceae, Alloprovetella, and Lactobacillus), and by reducing bacteria related to unhealthy profiles(Blautia, Faecalibaculum, Romboutsia and Bilophila). In conclusion, indicaxanthin has a positive effect on high-fat diet–induced neuronal damage and on the gut microbiota composition in obese mice.
文摘BACKGROUND Ulcerative colitis(UC)is a chronic and debilitating inflammatory bowel disease.Cumulative evidence indicates that excess hydrogen peroxide,a potent neutrophilic chemotactic agent,produced by colonic epithelial cells has a causal role leading to infiltration of neutrophils into the colonic mucosa and subsequent development of UC.This evidence-based mechanism identifies hydrogen peroxide as a therapeutic target for reducing agents in the treatment of UC.CASE SUMMARY Presented is a 41-year-old female with a 26-year history of refractory UC.Having developed steroid dependence and never achieving complete remission on treatment by conventional and advanced therapies,she began treatment with oral R-dihydrolipoic acid(RDLA),a lipid-soluble reducing agent with intracellular site of action.Within a week,rectal bleeding ceased.She was asymptomatic for three years until a highly stressful experience,when she noticed blood in her stool.RDLA was discontinued,and she began treatment with oral sodium thiosulfate pentahydrate(STS),a reducing agent with extracellular site of action.After a week,rectal bleeding ceased,and she resumed oral RDLA and discontinued STS.To date,she remains asymptomatic with normal stool calprotectin while on RDLA.CONCLUSION STS and RDLA are reducing agents that serve as highly effective and safe therapy for the induction and maintenance of remission in UC,even in patients refractory or poorly controlled by conventional and advanced therapies.Should preliminary findings be validated by subsequent clinical trials,the use of reducing agents could potentially prevent thousands of colectomies and represent a paradigm shift in the treatment of UC.

文摘The Bama diet(BD),Mediterranean diet(MD),and Japanese diet(JD)are three typical dietary patterns from distinct geographical regions.The aim of this study was to compare the efficacy of three diets in preventing colitis through gut microbe-metabolite-mediated regulatory mechanisms.This was achieved by integrating gut microbiome and metabolomics analyses.Results showed that BD could significantly increase the level of interleukin 10(IL-10),which has the potential to modulate the intestinal immune response.This was achieved by modulating the a-linoleic acid metabolism and promoting Akkermansia proliferation.MD elevated IL-10 level and increased the expression of tight junction proteins such as occludin,claudin-1,and zonula occludens-1.This effect might be attributed to the increased abundance of bifidobacteria,which impacted the primary bile acid biosynthesis pathway.JD decreased tumor necrosis factorαlevel and increased IL-10 level.This could be due to JD promoting the enrichment of Faecalibacterium,which affected the metabolism of arachidonic acid.Furthermore,the anti-inflammatory effects of the different metabolites,namely a-linoleic acid,cholic acid,and arachidonic acid,were confirmed using the RAW264.7 cellular inflammation model.

文摘Oxidized cholesterol(OXC)is a harmful dietary substance.Although the consumption of OXC has been associated with colonic inflammation,related underlying mechanisms are still limited.We evaluated the influence of dietary OXC on gut health and ecology by applying the murine model.Results showed that the thickness of the mucus layer was significantly reduced in healthy mice treated with OXC.Short-term intake of OXC did not influence the expression of pro-inflammatory factors in healthy mice but it induced the decrease of Muc2 expression in the proximal colon,accompanied by an increase in the abundance of 2 mucusdegrading bacteria,namely Akkermansia muciniphila and Bacteroides acidifaciens.Consistently,oral exposure of OXC promoted mucus barrier erosion in dextran sulfate sodium(DSS)-induced colitis mice and facilitated bacteria infiltration in the colon.The adverse effect of OXC on mucus layer disappeared in antibiotics-treated healthy mice,suggesting that the damaging effect of OXC on the gut mucus layer was not direct and instead was mediated by causing microbiota dysbiosis.Finally,the impact of OXC on the mucus layer and colitis was partly alleviated by green tea catechins.These studies demonstrated that the OXC-induced mucus barrier damage was mainly induced by the dysregulation of gut microbiota at least in this mouse model.
文摘Dear Editor,Life-history studies including dietary preferences and trophic interactions are essential for understanding community ecology in lizards(Pianka,1986).The family Agamidae is one of the largest in terms of species diversity and occurs in a variety of habitats(Uetz et al.,2024).
文摘BACKGROUND Chylous ascites(CA),which is characterized by lymphatic leakage into the peritoneal cavity,is a rare but significant complication of liver transplantation.Although dietary and pharmacological strategies have shown effectiveness in managing CA,standardized treatment protocols have yet to be established.AIMTo evaluate the comparative effectiveness of low-fat diet (LFD) enriched with medium-chain triglycerides (MCTs)vs octreotide therapy in managing post-liver transplantation CA.METHODSA comprehensive literature review was conducted to analyze the outcomes of dietary interventions and octreotidetherapy. The key parameters examined included resolution rates, treatment duration, and recurrence.RESULTSA comprehensive literature search yielded 13 studies that met the inclusion criteria, comprising 4 retrospectivecohort studies and 8 case studies. The incidence of CA following liver transplantation ranges from 0.6% to 4.7%.The onset varied, with a median time to diagnosis of 10 days after transplantation. A LFD with MCT supplementationwas used as the first-line therapy in 83.3% of the studies, with resolution rates ranging from 62.5% to100%. Octreotide therapy was utilized in 66.7% of the studies, primarily as a second-line therapy, with resolutionrates of 83.3% to 100%. Combination therapy showed a significantly higher resolution rate than did dietarymanagement alone (97.8% vs 78.9%, P = 0.02). The time to resolution was significantly shorter with octreotidecontainingregimens than with dietary management alone (median, 7 days vs 14 days;P = 0.03).CONCLUSIONA stepwise approach to CA management is recommended, initiating dietary interventions and escalating tooctreotide when necessary. Further research through well-designed randomized controlled trials is essential toestablish standardized treatment protocols for optimizing patient outcomes.
文摘Epidemiological studies indicate a strong correlation between various types of human cancer and dietary factors,whereas the specific mechanisms remain to be fully elucidated.Epigenetic alterations,such as DNA methylation,histone modifications,and noncoding RNA,are influenced by dietary components,especially phytochemicals and nutrients that participate in one-carbon metabolism.These alterations significantly impact cancer occurrence and progression.Consequently,epigenetic pathways may mediate the effects of diet on cancer risk.This review synthesizes the current information regarding the association of epigenetic alterations with cancer initiation and development,as well as the mechanisms by which diet exerts its influence on these changes.The goal of this minireview is to enhance the understanding of the roles of diet on epigenetic alterations to improve cancer prevention and treatment through diet.
文摘Background: Plant-based diets are eating patterns focusing on high intake of plant-basedfoods while limiting the intake of animal-based foods. In recent decades, plant-based dietshave received increasing attention for their potential benefits for humans and theenvironment. However, a comprehensive overview of the development trends and researchhotspots of plant-based diets is still lacking. Therefore, this scientometric study aimed to fillthis critical research gap. Methods: English literature related to plant-based diets publishedfrom 2012 to 2023 in Science Citation Index Expanded (SCIE) of Web of Science CoreCollection was collected on August 16, 2023, using relevant key terms. R-bibliometrix,CiteSpace, and VOSviewer were used to analyze data and construct knowledge graphs.Results: Overall, 4135 publications (3127 articles and 1008 reviews) were included in thisstudy, showing an obvious upward trend in this field annually from 2012 to 2023, rangingfrom 70 to 921. The USA published the highest number of studies (n =1158) and was theleading research center in this field worldwide. Universities were the main researchinstitutions;particularly, Harvard T.H. Chan School of Public Health contributed to thelargest number of publications (n = 88) and had an active cooperation with otherinstitutions. Mcclements DJ contributed the most publications (n = 49) and ranked firstamong the scholars in plant-based diets. The most productive academic journal (n = 353)on plant-based diets was Nutrients, with an IF2022 of 5.9, while Foods and Frontiers in Nutritionwere the relatively active journals in this field in recent years. “Quality,” “milk,” “culturedmeat,” “plant protein,” “environmental impacts,” “functional properties,” “plant-based meatalternative,” “dietary change,” “vegan diet,” “plant-based beverage,” “gut microbiota,”“middle-income countries,” and “chronic kidney disease” were the main research hotspotsand frontiers in the field of plant-based diets. Conclusion: This study provides acomprehensive overview of global research on plant-based diets. Although research in thisfield has gained increasing attention in recent decades, cooperation among differentinstitutions and researchers should be significantly strengthened. Moreover, more studiesare needed to further assess the health and environmental impacts of plant-based diets.

文摘Diet interventions such as calorie restriction or time-restricted feeding offer potential for weight management,but long-term success is often hindered by poor adherence due to the rewarding effects of sugars.In this study,we demonstrate that sulfur amino acid restriction(SAAR)diets promote rapid fat loss without impairing appetite and physiological locomotion,outperforming diets with restricted branched-chain amino acids.Weekly cycling of SAAR diets preserves metabolic benefits,such as reduced fat mass and improved glucose sensitivity.Metabolic analysis and in vivo isotope tracing revealed a shift toward carbohydrate oxidation in white and brown adipose tissue(WAT and BAT),and liver during the SAAR diet refeeding state,leading to decreased de novo lipogenesis.Enhanced lipolysis and fatty acid oxidation were observed in the heart,brain,BAT,lungs,etc.The reintroduction of methionine or cystine negated these metabolic benefits.Further 13C and 2H tracing experiments indicated that cystine,rather than its derivatives like taurine or H2S,directly regulates adiposity.In a high-fat diet model,SAAR diet led to sustained fat mass reduction,regardless of the timing of intervention.Additionally,cystine levels correlated positively with body mass index(BMI)and total triglycerides in diabetic patients.Our findings highlight SAAR diet as a promising strategy for long-term weight control by modulating systemic glucose and lipid metabolism homeostasis.
文摘BACKGROUND Picky eating is a commonly observed behavior among children globally,negatively impacting their physical and mental growth.Although common characteristics distinguish peaky eaters,including food selectivity,food neophobia,and food avoidance,there is no clear definition to assess this behavior.Due to the unavailability of data regarding picky eating,it wasn’t easy to estimate its prevalence.AIM To develop a regional protocol to help healthcare professionals identify and manage mild and moderate picky eating cases.METHODS A virtual roundtable discussion was held in April 2021 to gather the opinions of seven pediatricians and two pediatric dietitians from eight Middle Eastern countries who had great experience in the management of picky eating.The discussion covered different topics,including clearly defining mild and moderate picky eating,identifying the role of diet fortification in these cases,and the possibility of developing a systematic approach to diet fortification.RESULTS The panel identified picky eating as consuming an inadequate amount and variety of foods by rejecting familiar and unfamiliar food.Most of the time,moderate picky eating cases had micronutrient deficiencies with over-or undernutrition;the mild cases only showed inadequate food consumption and/or poor diet quality.Paying attention to the organic red flags like growth faltering and development delay and behavioral red flags,including food fixation and anticipatory gagging,will help healthcare professionals evaluate the picky eaters and the caregivers to care for their children.Although dietary supplementation and commercial food fortification play an important role in picky eating,they were no benefit in the Middle East.CONCLUSION The panel agreed that food fortification through a food-first approach and oral nutritional supplements would be the best for Middle Eastern children.These recommendations would facilitate identifying and managing picky-eating children in the Middle East.
文摘Purpose: In super-aging societies, prosthodontists will have a growing role and will need to improve their nutrition knowledge. This study aimed to evaluate the effectiveness of a workshop-based model for increasing dysphagia diet awareness among prosthodontists working with head and neck cancer patients. Methods: The study had a post-intervention design and included 10 maxillofacial prosthetic educators from eight countries who participated in a 120-minute workshop focused on theoretical and practical training in nutrition support for patients with dysphagia. Sessions were held in a specialized restaurant in Tokyo and included lectures, observation of Japanese cooking techniques, hands-on preparation of dysphagia-friendly foods, and cross-cultural comparisons. Knowledge, confidence, and practical application were assessed using a post-workshop questionnaire. Descriptive statistics and thematic analysis were used to evaluate outcomes. Results: Seven of the 10 prosthodontists completed the post-intervention questionnaire. All respondents reported overall satisfaction with the workshop. Session content was regarded as easy to understand by 57.14%, appropriate by 28.57%, and easy by 14.29%. Most respondents (85.71%) were “very satisfied” with the instructors’ explanations, and 100% were “very satisfied” with the workshop’s length and structure;71.42% felt they could apply the knowledge in clinical practice, while 28.58% anticipated challenges. The respondents appreciated the workshop’s focus on dysphagia, particularly in elderly patients, and valued the insights into Japanese dysphagia diets and culture. Conclusions: Workshops on nutrition provide an interactive platform for prosthodontists to enhance their knowledge and improve comprehensive patient care, highlighting the importance for prosthodontists to stay updated on developments in nutrition, particularly in dysphagia.

文摘Infancy and toddlerhood are critical phases of life,as the gut microbiota is established here,which influences current and future health.During this period,the microbiota was relatively less stable and highly responsive to environmental factors.Therefore,it is important to understand how dietary factors affect this complex stage of microbial assembly.The effect of feeding practices(breast milk/formula) on microbial colonization in early infancy has been actively studied;however,studies on the effect of diet on the gut microbiota during the complementary feeding period are sparse.The introduction of complementary foods provides abundant new dietary compounds for the gut microbiota,which induces a shift in gut microbiota and metabolism from milk-adapted toward a more mature and diverse adult-like community.Herein,we discuss the impact of dietary nutrients(carbohydrates,proteins,fats,vitamins,and minerals) on microbiome of infants and toddlers.Furthermore,this review summarizes the effects of complementary feeding patterns,specific foods(such as cereals;legumes and nuts;vegetables and fruits;meats;dairy products),food additives,and malnutrition(undernutrition or overnutrition) on gut microbiota of this populations.These findings might deepen our comprehension of the complex interactions between diets and the development and establishment of the gut microbiota.This may facilitate the tailoring of interventions aimed at promoting beneficial modifications within the gut microbial community.Furthermore,the insights gained could inform the design and implementation of safe and efficacious complementary feeding practices.

文摘Objective:To evaluate the therapeutic potential of coumarin-loaded chitosan nanoparticles(CNNPs)in managing high-fructose diet-induced diabetes and associated complications.Methods:CNNPs were synthesized using an ionic gelation method with chitosan coating and characterized.Rats with a high-fructose diet-induced diabetes were treated with coumarin and CNNPs(30,70,and 100 mg/kg)for 6-12 weeks.Metabolic,inflammatory,oxidative stress,organ function,and cardiovascular parameters were assessed,and qRT-PCR studies were carried out for measuring the mRNA expression of glucose transporter-4(GLUT-4),sirtuin-1(SIRT1),pyrin domain containing-3(NLRP3),sterol regulatory element binding protein 1c(SREBP-1c),forkhead box O3(FOXO3),and endothelial nitric oxide synthase(eNOS)genes.Results:Nanoparticle characterization revealed a Z-average size of 510.8 nm with a+14 mV zeta potential.CNNP treatment was more effective than coumarin,normalizing glycemic markers(glycosylated hemoglobin,serum insulin,and fasting blood glucose),and lipid profiles(total cholesterol,low-density lipoprotein cholesterol,triglycerides,and high-density lipoprotein cholesterol).Significant improvements were also seen in adipokines(adiponectin,chemerin,and leptin),inflammatory cytokines(interleukin-6 and tumor necrosis factor-α),and oxidative stress markers(catalase,superoxide dismutase and malonaldehyde).In addition,both treatments significantly upregulated the gene expression of SIRT1,GLUT-4,and eNOS,and downregulated FOXO3,SREBP-1c,and NLRP3.Histopathological studies confirmed that CNNPs ameliorated diabetes-induced structural abnormalities in major organs.Conclusions:CNNPs demonstrate improved bioavailability and therapeutic efficacy,offering a promising strategy for managing high-fructose diet-induced metabolic dysfunction and its complications.
