cognitive impairment and...BACKGROUND Hypertension is a common chronic disease in the elderly population,and its association with cognitive impairment has been increasingly recognized.Cognitive impairment,including mild cognitive impairment and dementia,can significantly affect the quality of life and independence of elderly individuals.Therefore,identifying risk factors for cognitive impairment in elderly hypertensive patients is crucial for developing effective interventions and improving health outcomes.Nutritional status is one of the potential factors that may influence cognitive function in elderly hypertensive patients.Malnutrition or inadequate nutrition can lead to various health problems,including weakened immune system,increased susceptibility to infections,and impaired physical and mental function.Furthermore,poor nutritional status has been linked to increased risk of cognitive decline and dementia in various populations.In this observational study,we aimed to investigate the nutritional status of elderly hypertensive patients and its relationship to the occurrence of cognitive impairment.By collecting baseline data on general information,body composition,and clinical indicators,we hope to identify risk factors for cognitive impairment in this patient population.The results of this study are expected to provide more scientific basis for the health management of elderly patients with hypertension,particularly in terms of maintaining good nutritional status and reducing the risk of cognitive impairment.AIM To explore the differences between clinical data and cognitive function of elderly hypertensive patients with different nutritional status,analyze the internal relationship between nutritional statuses and cognitive impairment,and build a nomogram model for predicting nutritional status in elderly hypertensive patients.METHODS The present study retrospectively analyzed 200 elderly patients admitted to our hospital for a hypertension during the period July 1,2024 to September 30,2024 as study subjects,and the 200 patients were divided into a modeling cohort(140 patients)and a validation cohort(60 patients)according to the ratio of 7:3.The modeling cohort were divided into a malnutrition group(26 cases),a malnutrition risk group(42 cases),and a normal nutritional status group(72 cases)according to the patients’Mini-Nutritional Assessment Scale(MNA)scores,and the modeling cohort was divided into a hypertension combined with cognitive impairment group(34 cases)and a hypertension cognitively normal group(106 cases)according to the Montreal Cognitive Assessment Scale(MoCA)scores,and the validation cohort was divided into a hypertension combined with cognitive impairment group(14 cases)and hypertension cognitively normal group(46 cases).The study outcome was the occurrence of cognitive impairment in elderly hypertensive patients.Univariate and multivariate logistic regression was used to explore the relationship between the general information of the elderly hypertensive patients and the influence indicators and the occurrence of cognitive impairment,the roadmap prediction model was established and validated,the patient work receiver operating characteristic curve was used to evaluate the predictive efficacy of the model,the calibration curve was used to assess the consistency between the predicted events and the actual events,and the decision curve analysis was used to evaluate the validity of the model.Pearson correlation analysis was used to explore the relationship between nutrition-related indicators and MoCA scores.RESULTS In this research,the modeling cohort comprised 140 cases,while the verification cohort consisted of 60 cases,with no notable discrepancy in the data between the two groups.In the modeling cohort,there were significant differences in body mass index(BMI),albumin(ALB),hemoglobin(Hb)and homocysteine levels among the malnourished group,the malnourished risk group and the normal nutritional status group.The results of univariate and multivariate analysis showed that BMI[odds ratio(OR)=0.830,P=0.014],ALB(OR=0.860,P=0.028),Hb(OR=0.939,P=0.035)and MNA score(OR=0.640,P=0.000)were independent protective factors for patients without cognitive impairment,and alkaline phosphatase(ALP)(OR=1.074,P=0.000)was an independent risk factor for patients with cognitive impairment.In this study,the prediction nomogram tailored for cognitive deterioration in elderly patients with hypertension demonstrated robust predictive power and a close correspondence between predicted and observed outcomes.This model offers significant potential as a means to forestall cognitive decline in hypertensive elderly patients.ALP was negatively correlated with MoCA score,while BMI,MNA score,Hb and ALB were positively correlated with MoCA score.CONCLUSION BMI,MNA score,Hb and ALB were independent protective factors for cognitive impairment in elderly hypertensive patients and were positively correlated with MoCA score.ALP was an independent risk factor for cognitive impairment in elderly hypertensive patients and was negatively correlated with the MoCA score.The column line graph model established in the study has a good predictive value.展开更多

This study aimed to investigate the best nutritional assessment method for leukemia patients after HSCT, and find the possible nutritional risk of the patients during the transplantation process in order to intervene in the patients with nutritional risks and undernourished patients timely, so that the entire transplantation process could be successfully completed. Methods： A prospective study was performed in 108 leukemia patients after HSCT, and different nutritional assessment methods, including nutritional risk screening 2002 （NRS2002）, mini nutritional assessment （MNA）, subjective globe assessment （SGA） and malnutritional universal screening tools （MUST）, were used. The associations between nutritional status of these patients and nutritional assessment methods were analyzed. Results： A total of 108 patients completed SGA, and 99 patients completed NRS2002, MNA and MUST. During the treatment process, 85.2% of the patients lost weight, wherein, 50% lost weight greater than 5%, and 42.6% had significantly reduced food intake. For nutritional risk assessment, the positive rates of NRS2002, MNA and MUST were 100%, 74.7% and 63.6%, respectively. There was a significant difference （P〈0.05） among the positive rates of NRS2002, MNA and MUST. In undernutrition assessment, the positive rate of SGA （83.3%） was significantly higher than that of MNA （17.2%） （P〈0.05）, and the incidence rate of nutritional risk among leukemia patients _〈30 years old was greater than that of patients 〉30 years old （P〈0.05）. Conclusions： Patients with leukemia were in poor nutritional status during and after HSCT. The leukemia patients 〈30 years old had a greater incidence rate of nutritional risk. As nutritional risk screening tool, the specificity of NRS2002 is not high, but it can be used for evaluating nutritional deficiencies. MNA is a good nutritional risk screening tool, but not an adequate tool for nutritional assessment. If assessment of undernutrition is necessary, the combination of all these screening tools and clinical laboratory indicators should he applied to improve accuracy.展开更多

Methods A cross-sectional study of 1,343 elderly inpatients was conducted in the Chinese PLA General Hospital. Nutrition Risk Screening（NRS 2002） and Subjective Global Assessment（SGA） were administered. Anthropometric measurements and blood biochemical indicators were obtained using standard techniques. The gender-and age-specific receiver operating characteristic（ROC） curves were constructed to evaluate the HGS for nutritional status by SGA and NRS 2002. Sensitivity, specificity, and areas under the curves（AUCs） were calculated. Results According to NRS 2002 and SGA, 63.81% of elderly inpatients were at nutritional risk and 28.22% were malnourished. Patients with higher HGS had an independently decreased risk of malnutrition and nutritional risk. The AUCs varied between 0.670 and 0.761. According to NRS 2002, the optimal HGS cut-points were 27.5 kg（65-74 years） and 21.0 kg（75-90 years） for men and 17.0 kg（65-74 years） and 14.6 kg（75-90 years） for women. According to SGA, the optimal HGS cut-points were 24.9 kg（65-74 years） and 20.8 kg（75-90 years） for men and 15.2 kg（65-74 years） and 13.5 kg（75-90 years） for women. Conclusion Elderly inpatients had increased incidence of malnutrition or nutritional risk. HGS cut-points can be used for assessing nutritional status in elderly inpatients at hospital admission in China.展开更多

The aim of this review is to support an interdisciplinary nutrition approach of these patients. Cirrhotic patients are frequently malnourished before LTx and this is associated with a poor prognosis. Although the relation between nutritional status versus survival, successful operation and recovery after LTx is well established, prevalence of malnutrition before the operation is still very high. Emerging research has also demonstrated that sarcopenia pre and post-transplant is highly prevalent, despite the weight gain in the postoperative period. The diagnosis of the nutritional status is the first step to address the adequate nutritional therapy. Nutritional recommendations and therapy to manage the nutritional status of LTx patients are discussed in this review, regarding counseling on adequate diets and findings of the latest research on using certain immunonutrients in these patients(branched chain amino-acids, pre and probiotics). Nutrition associated complications observed after transplantation is also described. They are commonly related to the adverse effects of immunosuppressive drugs, leading to hyperkalemia, hyperglycemia and weight gain. Excessive weight gain and post-transplant metabolic disorders have long been described in post-LTx and should be addressed in order to reduce associated morbidity and mortality.展开更多

文摘Chicken meat quality directly influences consumer acceptability and is crucial for the economic success of the poultry industry.Genetics and nutrition are key determinants of the meat quality traits in broilers.This review summarizes the research advances in this field,with a focus on the genetic and nutritional foundations that regulate intramuscular fat(IMF)deposition and meat quality in chickens over the past decade.The effects of embryonic nutrition,both maternal nutrition and in ovo feeding(IOF),on skeletal muscle development,the IMF content,and meat quality traits in broilers are also discussed.In genetics,single-cell RNA sequencing revealed that de novo lipogenesis predominantly occurs in myocytes,which is key to the formation of IMF in chicken muscle tissue.Fatty acid synthase(FASN)is the key enzyme involved in this process.This discovery has reshaped the traditional understanding of intramuscular lipid metabolism in poultry.Key genes,proteins,and pathways,such as FASN,FABP4,PPARG,C/EBPα,SLC27A1;LPL,APOA1,COL1A1;PPAR and ECM–receptor interactions signaling,have been identified to regulate IMF content and distribution by modulating fatty acid metabolism and adipogenesis.LncHLFF was innovatively found to promote ectopic IMF deposition in chickens via exosome-mediated mechanisms without affecting abdominal fat deposition.MiR-27b-3p and miR-128-3p were found to inhibit adipogenic differentiation by targeting PPARG,thereby affecting IMF formation.In nutrition,nutrigenomics research has shown that fructose enhances IMF deposition by activating ChREBP,providing new targets for nutritional interventions.Adjusting dietary components,including energy,protein,amino acids,fatty acids,and phytochemicals(e.g.,rutin),has been shown to significantly improve meat quality in broilers.Maternal nutrition(e.g.,intake of energy,amino acids,vitamins,and trace elements)and IOF(e.g.,N-carbamylglutamate)have also been confirmed to significantly impact offspring meat quality,opening new avenues for improving embryonic nutrition.Based on these significant advancements,this review proposes strategies that integrate genetic and nutritional approaches.These strategies aim to modulate the differentiation fate of paraxial mesenchymal stem cells toward myogenic or adipogenic lineages and the interaction between muscle and adipose tissues.These insights would help to improve meat quality while ensuring the growth performance of broiler chickens.

文摘BACKGROUND Hypertension is a common chronic disease in the elderly population,and its association with cognitive impairment has been increasingly recognized.Cognitive impairment,including mild cognitive impairment and dementia,can significantly affect the quality of life and independence of elderly individuals.Therefore,identifying risk factors for cognitive impairment in elderly hypertensive patients is crucial for developing effective interventions and improving health outcomes.Nutritional status is one of the potential factors that may influence cognitive function in elderly hypertensive patients.Malnutrition or inadequate nutrition can lead to various health problems,including weakened immune system,increased susceptibility to infections,and impaired physical and mental function.Furthermore,poor nutritional status has been linked to increased risk of cognitive decline and dementia in various populations.In this observational study,we aimed to investigate the nutritional status of elderly hypertensive patients and its relationship to the occurrence of cognitive impairment.By collecting baseline data on general information,body composition,and clinical indicators,we hope to identify risk factors for cognitive impairment in this patient population.The results of this study are expected to provide more scientific basis for the health management of elderly patients with hypertension,particularly in terms of maintaining good nutritional status and reducing the risk of cognitive impairment.AIM To explore the differences between clinical data and cognitive function of elderly hypertensive patients with different nutritional status,analyze the internal relationship between nutritional statuses and cognitive impairment,and build a nomogram model for predicting nutritional status in elderly hypertensive patients.METHODS The present study retrospectively analyzed 200 elderly patients admitted to our hospital for a hypertension during the period July 1,2024 to September 30,2024 as study subjects,and the 200 patients were divided into a modeling cohort(140 patients)and a validation cohort(60 patients)according to the ratio of 7:3.The modeling cohort were divided into a malnutrition group(26 cases),a malnutrition risk group(42 cases),and a normal nutritional status group(72 cases)according to the patients’Mini-Nutritional Assessment Scale(MNA)scores,and the modeling cohort was divided into a hypertension combined with cognitive impairment group(34 cases)and a hypertension cognitively normal group(106 cases)according to the Montreal Cognitive Assessment Scale(MoCA)scores,and the validation cohort was divided into a hypertension combined with cognitive impairment group(14 cases)and hypertension cognitively normal group(46 cases).The study outcome was the occurrence of cognitive impairment in elderly hypertensive patients.Univariate and multivariate logistic regression was used to explore the relationship between the general information of the elderly hypertensive patients and the influence indicators and the occurrence of cognitive impairment,the roadmap prediction model was established and validated,the patient work receiver operating characteristic curve was used to evaluate the predictive efficacy of the model,the calibration curve was used to assess the consistency between the predicted events and the actual events,and the decision curve analysis was used to evaluate the validity of the model.Pearson correlation analysis was used to explore the relationship between nutrition-related indicators and MoCA scores.RESULTS In this research,the modeling cohort comprised 140 cases,while the verification cohort consisted of 60 cases,with no notable discrepancy in the data between the two groups.In the modeling cohort,there were significant differences in body mass index(BMI),albumin(ALB),hemoglobin(Hb)and homocysteine levels among the malnourished group,the malnourished risk group and the normal nutritional status group.The results of univariate and multivariate analysis showed that BMI[odds ratio(OR)=0.830,P=0.014],ALB(OR=0.860,P=0.028),Hb(OR=0.939,P=0.035)and MNA score(OR=0.640,P=0.000)were independent protective factors for patients without cognitive impairment,and alkaline phosphatase(ALP)(OR=1.074,P=0.000)was an independent risk factor for patients with cognitive impairment.In this study,the prediction nomogram tailored for cognitive deterioration in elderly patients with hypertension demonstrated robust predictive power and a close correspondence between predicted and observed outcomes.This model offers significant potential as a means to forestall cognitive decline in hypertensive elderly patients.ALP was negatively correlated with MoCA score,while BMI,MNA score,Hb and ALB were positively correlated with MoCA score.CONCLUSION BMI,MNA score,Hb and ALB were independent protective factors for cognitive impairment in elderly hypertensive patients and were positively correlated with MoCA score.ALP was an independent risk factor for cognitive impairment in elderly hypertensive patients and was negatively correlated with the MoCA score.The column line graph model established in the study has a good predictive value.
文摘Objective： Correct nutritional assessment is essential for leukemia patients after hematopoietic stem cell transplantation （HSCT）. This study aimed to investigate the best nutritional assessment method for leukemia patients after HSCT, and find the possible nutritional risk of the patients during the transplantation process in order to intervene in the patients with nutritional risks and undernourished patients timely, so that the entire transplantation process could be successfully completed. Methods： A prospective study was performed in 108 leukemia patients after HSCT, and different nutritional assessment methods, including nutritional risk screening 2002 （NRS2002）, mini nutritional assessment （MNA）, subjective globe assessment （SGA） and malnutritional universal screening tools （MUST）, were used. The associations between nutritional status of these patients and nutritional assessment methods were analyzed. Results： A total of 108 patients completed SGA, and 99 patients completed NRS2002, MNA and MUST. During the treatment process, 85.2% of the patients lost weight, wherein, 50% lost weight greater than 5%, and 42.6% had significantly reduced food intake. For nutritional risk assessment, the positive rates of NRS2002, MNA and MUST were 100%, 74.7% and 63.6%, respectively. There was a significant difference （P〈0.05） among the positive rates of NRS2002, MNA and MUST. In undernutrition assessment, the positive rate of SGA （83.3%） was significantly higher than that of MNA （17.2%） （P〈0.05）, and the incidence rate of nutritional risk among leukemia patients _〈30 years old was greater than that of patients 〉30 years old （P〈0.05）. Conclusions： Patients with leukemia were in poor nutritional status during and after HSCT. The leukemia patients 〈30 years old had a greater incidence rate of nutritional risk. As nutritional risk screening tool, the specificity of NRS2002 is not high, but it can be used for evaluating nutritional deficiencies. MNA is a good nutritional risk screening tool, but not an adequate tool for nutritional assessment. If assessment of undernutrition is necessary, the combination of all these screening tools and clinical laboratory indicators should he applied to improve accuracy.

文摘Deep phenotyping and genetic characterization of individuals are fundamental to assessing the metabolic status and determining nutrition-specific requirements.This study aimed to ascertain the utmost effectiveness of personalized interventions by aligning dietary adjustments with both the genotype and metabolotype of individuals.Therefore,we assessed here the usefulness of a polygenic score(PGS)characterizing a potential pro-inflammatory profile(PGSi)as a nutrigenetic tool to discern individuals from the Danish PREVENTOMICS cohort that could better respond to precision nutrition(PN)plans,specifically targeted at counteracting the low-grade inflammatory profile typically found in obesity.The cohort followed a PN plan to counteract the pro-inflammatory profile(PNi group)or generic dietary recommendations(Control)for 10 weeks.PGSi was applied for genetic stratification(Low/High).The effects of the intervention on anthropometrics and biomarkers related to inflammatory profile and carbohydrate metabolism were assessed.Around 30%of subjects had a high genetic predisposition to pro-inflammatory status(high-PGSi).These individuals demonstrated the most effective response to the dietary plan,experiencing improved body composition,with significant decreases in body weight(∆:-4.84%;P=0.039)and body fat(∆:-4.86%;P=0.007),and beneficial changes in pro-and anti-inflammatory biomarkers,with significant increases in IL-10(∆:71.3%;P=0.025)and decreases in TNF-α(∆:-3.0%;P=0.048),CRP(∆:-31.1%),ICAM1(∆:-5.8%),and MCP1(∆:-4.2%)circulating levels,compared to low-PGSi individuals.Both phenotypic and genetic stratification contributed to a better understanding of metabolic heterogeneity in response to diet.This approach allows for refinement of the prediction of individual requirements and potentially for better management of obesity.
文摘BACKGROUND Hashimoto’s thyroiditis(HT)is an autoimmune dysfunction caused by genetic and environmental changes that attack the thyroid gland.HT affects approximately 2%to 5%of the population,being more prevalent in women.It is diagnosed through a blood test(anti-thyroid peroxidase).Pharmacological treatment consists of daily administration of the synthetic hormone levothyroxine on an empty stomach.The most common signs and symptoms are:Tissue resistance to triiodothyronine T3,weight gain,dry skin,hair loss,tiredness/fatigue,and constipation,and nutritional therapy appears to help reduce these symptoms.AIM To analyze nutritional interventions for treating HT.METHODS This is an integrative review of original studies on nutritional interventions for treating Hashimoto’s disease.Articles were searched in the MEDLINE/PubMed and Latin American and Caribbean Literature on Health Sciences(LILACS)databases via virtual health library,using controlled vocabulary and free terms.A total of 70 articles were found:67 from PubMed and 3 from LILACS.After exclusions,9 articles met the eligibility criteria,including dietary interventions for maintaining and restoring the patient’s quality of life.RESULTS The reviewed articles evaluated the nutritional treatment of HT through supplementation of deficient micronutrients,anti-inflammatory diets,gluten-free diets,exclusion of foods that cause food sensitivities,lactose-free diet,paleo diet,and calorie restriction diets.However,some results were controversial regarding the beneficial effects of HT.CONCLUSION In general,it was observed that nutritional interventions for HT are based on the recovery of micronutrient deficiencies,treatment of the intestinal microbiota,diet rich in foods with anti-inflammatory properties,lifestyle changes,and encouragement of healthy habits.

文摘BACKGROUND Colorectal cancer is a prevalent malignancy with suboptimal postoperative recovery outcomes.Enhancing recovery and prolonging disease-free survival remains a critical challenge.This study investigates factors influencing the efficacy of probiotics combined with enteral nutrition in postoperative patients with colorectal cancer.AIM To identify predictors of therapeutic efficacy for probiotics combined with enteral nutrition in postoperative patients with colorectal cancer.METHODS A retrospective study was conducted with 511 patients with colorectal cancer who underwent surgery and received probiotics and enteral nutrition from January 2022 to March 2025.Patients were categorized into the“good efficacy group”(n=279)and“poor efficacy group”(n=232)based on outcomes observed 3 months post-surgery.Variables assessed included gut microbiota composition,nutritional intake,immune and inflammatory markers,and demographic characteristics.RESULTS Patients with favorable outcomes were typically younger,had higher caloric,protein,and fiber intake,and displayed enhanced intestinal mucosal barrier function with elevated levels of Bifidobacterium and Lactobacillus.Immune markers such as immunoglobulin A,immunoglobulin M,immunoglobulin G,and CD4+/CD8+T-cell ratios were significantly higher in the good efficacy group.High numbers of Fusobacterium nucleatum and Bacteroides fragilis and levels of tumor necrosis factor-alpha and interleukin-6 were associated with poor efficacy.Multivariate analysis identified age,tumor node metastasis stage,protein intake,and gut microbiota composition as significant predictors of therapeutic success.CONCLUSION The efficacy of combining probiotics with enteral nutrition in postoperative patients with colorectal cancer was influenced by age,nutritional intake,microbiota balance,immune status,and inflammatory markers.
文摘BACKGROUND Cirrhotic patients face heightened energy demands,leading to rapid glycogen depletion,protein degradation,oxidative stress,and inflammation,which drive disease progression and complications.These disruptions cause cellular damage and parenchymal changes,resulting in vascular alterations,portal hypertension,and liver dysfunction,significantly affecting patient prognosis.AIM To analyze the association between Child–Turcotte–Pugh(CTP)scores and di-fferent nutritional indicators with survival in a 15-year follow-up cohort.METHODS This was a retrospective cohort study with 129 cirrhotic patients of both sexes aged>18 years.Diagnosis of cirrhosis was made by liver biopsy.The first year of data collection was 2007,and data regarding outcomes were collected in 2023.Data were gathered from medical records,and grouped by different methods,including CTP,handgrip strength,and triceps skinfold cutoffs.The prognostic values for mortality were assessed using Kaplan–Meier curves and multivariate binary logistic regression models.RESULTS The coefficient for CTP was the only statistically significant variable(Wald=5.193,P=0.023).This suggests that with a negative change in CTP classification score,the odds of survival decrease 52.6%.The other evaluated variables did not significantly predict survival outcomes in the model.Kaplan–Meier survival curves also indicated that CTP classification was the only significant predictor.CONCLUSION Although different classifications showed specific differences in stratification,only CTP showed significant predictive potential.CTP score remains a simple and effective predictive tool for cirrhotic patients even after longer follow-up.
文摘Background:Undernutrition poses a major threat for the growth and development of children in remote island regions of Bangladesh.Methods:This study investigated the prevalence and risk predictors of undernutrition among children under five in the island regions of Bangladesh.A cross‐sectional study was conducted in 13 unions across two islands,with a random sample of 549 children.Results:Descriptive analyses showed that underweight(Z‐score<−2),wasting(Z‐score<−2),and stunting(Z‐score<−2)were prevalent,with rates of 36.80%,24.60%,and 47.20%,respectively.Significant predictors of underweight included a history of diarrhea(AOR=2.24,p<0.001),acute respiratory infection(ARI)(AOR=1.84,p<0.01),anemic caregivers(AOR=1.52,p<0.05),and belonging to day labor families(AOR=0.29,p<0.01).Childhood wasting was significantly associated with partial vaccination(AOR=2.84,p<0.001),large family size(AOR=1.79,p<0.05),higher birth order(AOR=0.58,p<0.05),diarrhea(AOR=3.09,p<0.001),anemic mothers(AOR=1.89,p<0.05),primary(AOR=3.35,p<0.05)and secondary(AOR=4.11,p<0.01)maternal education,and fathers working abroad(AOR=0.42,p<0.05)or as daily laborers(AOR=0.17,p<0.001).Stunting was more common among children with partial vaccination,diarrhea,and ARI,and less common among those with a history of fever or those from day laborer families.Conclusion:Overall,undernutrition among children in the island areas of Bangladesh is influenced by multiple factors,necessitating a multisectoral approach to improve their nutritional status.

文摘BACKGROUND Body composition analysis(BCA)is primarily used in the management of conditions such as obesity and endocrine disorders.However,its potential in providing nutritional guidance for patients with Alzheimer’s disease(AD)remains relatively unexplored.AIM To explore the clinical efficacy of BCA-based dietary nutrition scheme on bone metabolism in AD patients.METHODS This retrospective study included 96 patients with AD complicated by osteoporosis who were admitted to The Third Hospital of Quzhou between January 2023 and December 2024.Based on data from previous similar studies,the patients were randomly assigned to either a routine diet(RD)group(n=48)or a personalized nutrition(PN)group(n=48).The RD group received conventional dietary guidance,while the PN group received individualized diet intervention measures based on human BCA.The intervention period lasted for 12 weeks.Bone mineral density(BMD),body mass index(BMI),muscle mass,mineral content,osteocalcin,25-hydroxyvitamin D,procollagen type I N-terminal propeptide(PINP),beta C-terminal telopeptide of type I collagen(β-CTX),and serum calcium were measured and compared between the two groups before and 12 weeks after the intervention.RESULTS No significant differences were observed between groups in terms of age,sex,height,BMI,or other baseline data(P>0.05).In both groups,BMI did not show significant changes after the intervention(P>0.05),whereas muscle mass and mineral content were significantly increased(P<0.05).After the intervention,BMI in the PN group did not differ significantly from that of the RD group,but muscle mass and mineral content were significantly higher in the PN group(P<0.05).After the intervention,a higher proportion of patients in the PN group had a T score>-1 compared to the RD group(P<0.05).The mini-mental state examination(MMSE)score was similar in both groups before the intervention.However,12 weeks after the intervention,the MMSE score in the PN group was significantly higher than that in the RD group(P<0.05).In both groups,the MMSE score significantly increased 12 weeks post-intervention compared to pre-intervention levels(P<0.05).Before the intervention,the levels of osteocalcin,serum calcium,PINP,β-CTX,and 25-hydroxyvitamin D were not significantly different between the two groups(P>0.05).After 12 weeks of intervention,the PN group exhibited higher levels of osteocalcin,serum calcium,and 25-hydroxyvitamin D,as well as lower levels of PINP andβ-CTX,compared to the RD group(P<0.05).In both groups,osteocalcin,serum calcium,and 25-hydroxyvitamin D levels were significantly higher,while PINP andβ-CTX levels were significantly lower after 12 weeks of intervention compared to baseline(P<0.05).CONCLUSION The human BCA-based dietary nutrition regimen plays a crucial role in improving BMD and bone metabolism,with effects that surpass those of conventional nutrition strategies.The findings of this study provide strong evidence for the nutritional management of AD patients.
文摘Objective To assess nutritional status and define gender-and age-specific handgrip strength（HGS） cut-point values for malnutrition or nutritional risk in elderly inpatients. Methods A cross-sectional study of 1,343 elderly inpatients was conducted in the Chinese PLA General Hospital. Nutrition Risk Screening（NRS 2002） and Subjective Global Assessment（SGA） were administered. Anthropometric measurements and blood biochemical indicators were obtained using standard techniques. The gender-and age-specific receiver operating characteristic（ROC） curves were constructed to evaluate the HGS for nutritional status by SGA and NRS 2002. Sensitivity, specificity, and areas under the curves（AUCs） were calculated. Results According to NRS 2002 and SGA, 63.81% of elderly inpatients were at nutritional risk and 28.22% were malnourished. Patients with higher HGS had an independently decreased risk of malnutrition and nutritional risk. The AUCs varied between 0.670 and 0.761. According to NRS 2002, the optimal HGS cut-points were 27.5 kg（65-74 years） and 21.0 kg（75-90 years） for men and 17.0 kg（65-74 years） and 14.6 kg（75-90 years） for women. According to SGA, the optimal HGS cut-points were 24.9 kg（65-74 years） and 20.8 kg（75-90 years） for men and 15.2 kg（65-74 years） and 13.5 kg（75-90 years） for women. Conclusion Elderly inpatients had increased incidence of malnutrition or nutritional risk. HGS cut-points can be used for assessing nutritional status in elderly inpatients at hospital admission in China.
文摘Managing malnutrition before liver transplantation(LTx) while on the waiting list and, excessive weight gain/metabolic disturbances in post-surgery are still a challenge in LTx care. The aim of this review is to support an interdisciplinary nutrition approach of these patients. Cirrhotic patients are frequently malnourished before LTx and this is associated with a poor prognosis. Although the relation between nutritional status versus survival, successful operation and recovery after LTx is well established, prevalence of malnutrition before the operation is still very high. Emerging research has also demonstrated that sarcopenia pre and post-transplant is highly prevalent, despite the weight gain in the postoperative period. The diagnosis of the nutritional status is the first step to address the adequate nutritional therapy. Nutritional recommendations and therapy to manage the nutritional status of LTx patients are discussed in this review, regarding counseling on adequate diets and findings of the latest research on using certain immunonutrients in these patients(branched chain amino-acids, pre and probiotics). Nutrition associated complications observed after transplantation is also described. They are commonly related to the adverse effects of immunosuppressive drugs, leading to hyperkalemia, hyperglycemia and weight gain. Excessive weight gain and post-transplant metabolic disorders have long been described in post-LTx and should be addressed in order to reduce associated morbidity and mortality.
文摘The pancreas is a major player in nutrient digestion.In chronic pancreatitis both exocrine and endocrine insufficiency may develop leading to malnutrition over time.Maldigestion is often a late complication of chronic pancreatic and depends on the severity of the underlying disease.The severity of malnutrition is correlated with two major factors:(1)malabsorption and depletion of nutrients(e.g.,alcoholism and pain)causes impaired nutritional status;and(2)increased metabolic activity due to the severity of the disease.Nutritional deficiencies negatively affect outcome if they are not treated.Nutritional assessment and the clinical severity of the disease are important for planning any nutritional intervention.Good nutritional practice includes screening to identify patients at risk,followed by a thoroughly nutritional assessment and nutrition plan for risk patients.Treatment should be multidisciplinary and the mainstay of treatment is abstinence from alcohol,pain treatment,dietary modifications and pancreatic enzyme supplementation.To achieve energy-end protein requirements,oral supplementation might be beneficial.Enteral nutrition may be used when patients do not have sufficient calorie intake as in pylero-duodenalstenosis,inflammation or prior to surgery and can be necessary if weight loss continues.Parenteral nutrition is very seldom used in patients with chronic pancreatitis and should only be used in case of GI-tract obstruction or as a supplement to enteral nutrition.
