Nutritional Support Therapy Research Articles

Forty-fifth ASPEN Presidential Address: Medical nutrition therapy, is it time to get personal?

The time could not be riper for the field of nutrition as it moves into the forefront being recognized as a major influencer in the prevention and management of many diseases. The approach to nutrition support therapy, which includes oral diet and enteral and parenteral nutrition, has historically involved approaching patients in the same "one size fits all" manner. However, as research methodologies have advanced over the past decade, data suggest that although people may be grouped into having a particular disease or condition, their nutrition therapeutic intervention may be optimized if it is personalized. This thought-provoking session will discuss current dietary guidelines and provide evidence and pose opportunities toward a future direction incorporating a personalized therapeutic nutrition support approach, which takes into consideration the metabolic capacity of the gut microbiome.

Nutritional status and prognostic factors for mortality in patients admitted to emergency department observation units: a national multi-center study in China.

Nutritional risk is common among patients admitted to the emergency department and is associated with adverse clinical outcomes. Despite its large population, few comprehensive studies have been conducted in China concerning the nutritional status of patients admitted to emergency department observation units (EDOUs). Patients admitted to EDOUs of 90 tertiary hospitals in China between June 2020 and December 2020 were enrolled. Demographic information, laboratory parameters, nutritional support therapies, and 28-day mortality were recorded. Risk factors for mortality were examined using multi-variate-adjusted logistic regression analysis. Receiver operating characteristic (ROC) curves for each predictor of mortality were plotted, and the area under the ROC (AUROC) curves was compared. A total of 2,005 eligible patients were finally enrolled. At the 28-day follow-up, 1,911 patients survived, and 94 died. The group with a Nutritional Risk Screening 2002 (NRS 2002) score of 3-4 points was the largest (52.01%). The number of patients receiving oral nutritional supplements, enteral nutrition (EN), parenteral nutrition (PN), and the combination of EN and PN was 425, 314, 853, and 413, respectively. Among the total, 77.55% of patients had nutritional risk (NRS 2002 ≥3). The proportion of patients with high nutritional risk (NRS2002≥5) in the age group >80 years was significantly higher than that in the age group 66-80 years (29.00% vs. 23.93%, P=0.032), but not significantly higher than that in the age group 18-65 years (29.00% vs. 26.54%, P=0.449). Logistic regression analysis revealed that heart failure (odds ratio [OR] 1.856, 95% confidence interval [CI] 1.087-3.167, P=0.023), consciousness (OR 2.967, 95% CI 1.894-4.648, P<0.001), Acute Physiology and Chronic Health Evaluation II (APACHE II) score (OR 1.037, 95% CI 1.017-1.058, P<0.001), NRS 2002 score (OR 1.286, 95% CI 1.115-1.483, P=0.001), and Mini Nutritional Assessment-Short Form score (OR 0.946, 95% CI 0.898-0.997, P=0.039) were all independent risk factors for 28-day mortality. APACHE II and NRS 2002 scores were superior to other predictors according to the comparison of AUROC. Nutritional risk is prevalent among older patients in EDOUs in China. APACHE II and NRS 2002 scores are important risk factors for mortality in patients admitted to the EDOU. Timely and appropriate nutritional screening and support measures are critical to reduce patients' length of hospital stay and mortality.

Принципы интенсивной терапии огнестрельных ранений черепа и головного мозга

With the modern development of battlefield medicine and air ambulance evacuation, the quality of medical care is undergoing changes. As for neurosurgical combat trauma, the provision of medical care for this patient population requires more specialization, closer to the front line and reduction of stages. The article summarizes the results of experience in the treatment of gunshot wounds to the head. The severity of injuries to the skull and brain on admission was assessed using the Injury Severity Score. The condition of 67% of those admitted was considered severe, the mortality rate was 0.8%, and the length of stay in the intensive care unit was 12 days. Extremely severe were 33% of the wounded, the mortality rate in this group was 2.2%, and the length of stay in the intensive care unit (ICU) was 31 days. When assessing the level of consciousness at our stage on the Glasgow coma scale, most of the wounded had a score of 6–8, which corresponds to a deep coma. Direct evacuation of the wounded to the specialized stage of care, computed tomography (CT), availability of a qualified neurosurgeon, the earliest possible decompressive craniotomy if indicated are the components of success in dealing with intracranial hypertension, the development of subsequent neurological deficit and reducing mortality. Nutritional support and antibiotic therapy are important components of intensive care in neuroresuscitation.

Potential Therapeutic Strategies for Skeletal Muscle Atrophy.

The maintenance of muscle homeostasis is vital for life and health. Skeletal muscle atrophy not only seriously reduces people's quality of life and increases morbidity and mortality, but also causes a huge socioeconomic burden. To date, no effective treatment has been developed for skeletal muscle atrophy owing to an incomplete understanding of its molecular mechanisms. Exercise therapy is the most effective treatment for skeletal muscle atrophy. Unfortunately, it is not suitable for all patients, such as fractured patients and bedridden patients with nerve damage. Therefore, understanding the molecular mechanism of skeletal muscle atrophy is crucial for developing new therapies for skeletal muscle atrophy. In this review, PubMed was systematically screened for articles that appeared in the past 5 years about potential therapeutic strategies for skeletal muscle atrophy. Herein, we summarize the roles of inflammation, oxidative stress, ubiquitin-proteasome system, autophagic-lysosomal pathway, caspases, and calpains in skeletal muscle atrophy and systematically expound the potential drug targets and therapeutic progress against skeletal muscle atrophy. This review focuses on current treatments and strategies for skeletal muscle atrophy, including drug treatment (active substances of traditional Chinese medicine, chemical drugs, antioxidants, enzyme and enzyme inhibitors, hormone drugs, etc.), gene therapy, stem cell and exosome therapy (muscle-derived stem cells, non-myogenic stem cells, and exosomes), cytokine therapy, physical therapy (electroacupuncture, electrical stimulation, optogenetic technology, heat therapy, and low-level laser therapy), nutrition support (protein, essential amino acids, creatine, β-hydroxy-β-methylbutyrate, and vitamin D), and other therapies (biomaterial adjuvant therapy, intestinal microbial regulation, and oxygen supplementation). Considering many treatments have been developed for skeletal muscle atrophy, we propose a combination of proper treatments for individual needs, which may yield better treatment outcomes.

Surgical implications of HIV infection

According to the joint United Nations Programme on HIV/AIDS (UNAIDS), 37.7 million adults and children worldwide were estimated to be living with HIV or acquired immune deficiency syndrome (AIDS) at the end of 2020 [UNAIDS. (2022). http://www.unaids.org . Accessed 30 May 2022]. Most reside in low- and middle-income countries, with approximately 67% in sub-Saharan Africa (SSA). At the end of 2020, the total number of children less than 15years of age living with HIV infection was 2.6 million, of whom 2.3 million (88%) were living in SSA. Aggressive interventions have reduced the annual number of incident (new) HIV infections among children to around 150,000 [UNAIDS. (2022). http://www.unaids.org . Accessed 30 May 2022]. However, paediatric HIV infection remains a pandemic affecting children predominantly in SSA but is also seen in Asia and sporadically elsewhere particularly in areas of civil strife such as is currently the case in Ukraine [War in Ukraine. (2022). https://www.unaids.org/en/War-Ukraine-special . Accessed Apr 2022]. New HIV infections among children declined by more than half (54%) from 2010 to 2020, due mainly to the increased provision of antiretroviral therapy to pregnant and breastfeeding women living with HIV [UNAIDS. (2022). http://www.unaids.org . Accessed 30 May 2022]. These programmes include early identification of HIV infection in pregnant or breastfeeding women through routine HIV testing, provision of antiretroviral therapy (ART) to all HIV-infected women who are pregnant or breastfeeding, provision of antiretroviral prophylaxis to their newborn infants during the first 6-12weeks of life, delivery by elective Caesarean section when indicated, promotion of exclusive breastfeeding, early infancy screening for HIV infection, and initiation of ART in infants with HIV infection. HIV-infected children may require surgery either as an emergency to deal with a life-threatening incidental condition unrelated to HIV infection or for a complication of the disease such as tuberculosis or an aggressive soft tissue infection like necrotising fasciitis. Non-emergency surgical procedures may be required to assist in the diagnosis of an HIV-related condition or to correct a routine surgical problem electively. Surgical conditions associated with HIV infection are described under categories of soft tissue or organ-specific infections requiring drainage or debridement; gastrointestinal tract disease and complications; infections in the perineal area; malignancies and HIV-associated vasculitis. Although surgical outcomes are less favourable in HIV-infected children, pre-operative treatment of coinfections, administration of cotrimoxazole prophylaxis, nutritional support and antiretroviral therapy, together with peri-operative antibiotic prophylaxis have resulted in excellent short-term outcomes [World Health Organization. Consolidated guidelines on the use of antiretroviral drugs for treating and preventing HIV infection: Recommendations for a public health approach, June 201 http://www.apps.who.int/iris/bitstream/10665/85321/1/9789241505727_eng.pdf?ua=1 ; World Health Organization Guideline on when to start antiretroviral therapy and on pre-exposure prophylaxis for HIV, September 2015. http://www.apps.who.int/iris/bitstream/10665/186275/1/9789241509565_eng.pdf?ua=1;Eley et al. in BMC Infect Dis 2:3, 2002;Karpelowsky et al. in Pediatr Surg Int 28:1007-1014, 2012;].

Improving Administration and Documentation of Enteral Nutrition Support Therapy in a Veteran Affairs Health Care System: Use of Medication Administration Record and Bar Code Scanning Technology.

The goal of this project was to evaluate and improve the ordering, administration, documentation, and monitoring of enteral nutrition therapies within the inpatient setting in a Veteran's Health Administration system. An interdisciplinary team of clinicians reviewed the literature for best practices and revised the process for enteral nutrition support for hospitalized veterans. Interventions included training staff, revising workflows to include scanning patients and products, including enteral nutrition orders within the medication administration record (MAR), and using the existing bar code medication administration system for administration, documentation, and monitoring. Baseline and postprocess improvement outcomes over a year period were collected and analyzed for quality improvement opportunities. Before process change, only 60% (33/55) of reviewed enteral nutrition orders were documented and 40% (22/55) were not documented in the intake flowsheet of the electronic health record. In the year after adding enteral nutrition therapies to the MAR and using bar code scanning, a total of 3807 enteral nutrition products were evaluated. One hundred percent of patients were bar code scanned, 3106/3807 (82%) products were documented as given, 447/3807 (12%) were documented as held (with comments), 12/3807 (<1%) were documented as missing/unavailable, and 242/3807 (6%) were documented as refused. Inclusion of enteral nutrition order sets on the MAR and using bar code scanning technology resulted in sustained improvements in safety, administration, and documentation of enteral therapies for hospitalized veterans.

Nutritional Support in Patients with Colorectal Cancer: State of Knowledge and Perspectives

Many cancer patients have a nutritional risk. Nutritional support therapy plays an important role in cancer treatment, especially for the patients with digestive system cancer. Nutritional support therapy for tumor patients should be based on the specific saturations. For example, types of tumors, degree of differentiation, and nutritional status of the patients need to be evaluated in detail, and then propose the specific implementation approach. For the colorectal cancer patients with promising treatment prospects, nutritional support should be standardized and make every effort to improve the safety and effectiveness of treatment. This article reviews the research progress on nutritional support therapy for colorectal cancer patients thereby promoting the standardized development of nutritional support therapy and better guiding the clinical nutritional support practice. In addition, this paper discussed the feasibility of a combination of nutritional and exercise interventions to efficiently improve muscle and strength, physical function, nutritional status, fatigue, and quality of life in colorectal cancer patients. Establishing a standard process for nutritional support should become an interdisciplinary task. Standard procedures and quality control should also be specified to ensure the effectiveness of nutritional therapy. The current knowledge, and perspectives of application of nutritional support in patients with colorectal cancer in this paper could provide a good reference for the future research of cancer diagnosis and treatment.

Analysis of the causes of failed placement of nasoenteric tube under DSA guidance and treatment strategies for successful re-catheterization.

For patients with advanced cancer or patients who have undergone digestive tract reconstruction, enteral nutrition is the most important nutritional support therapy, which can reduce the risk of enteral infection and improve self-immunity; while digital subtraction angiography (DSA) guided nasoenteric tube placement is suitable for nutritional support and palliative treatment of most patients with advanced cancer, many doctors because the preoperative preparation is not sufficient or the intraoperative operation is not standardized, resulting in catheter failure can not achieve the purpose of nutritional supply, and we need to summarize the lessons of failure and optimize the catheterization strategy. From February 2015 to July 2020, A total of 3,810 cases were treated with DSA guided nasoenteric feeding tube placement. According to the requirements that enteral nutrition could not be performed by the initial catheterization, 94 cases of catheterization failure were selected as the study subjects. The causes of catheterization failure were analyzed and summarized by analyzing the intraoperative image data and operation process; 42 cases of catheterization failure experienced successful catheterization after re-catheterization. By studying the relevant preoperative preparation and intraoperative operation, the treatment strategies and operation methods for successful re-catheterization were summarized. In 94 patients with primary catheterization failure, anastomotic stenosis or obstruction accounted for 20.2%, excessive dilatation of gastric lumen accounted for 17.0%, pyloric stenosis or obstruction of antrum accounted for 13.8%, efferent loop stenosis or obstruction accounted for 11.7%, and the above factors were the main causes of DSA guided feeding tube failure; of the 42 patients with successful recatheterization, 9 patients underwent adequate negative pressure drainage before surgery, 7 patients modified the projection angle by adjusting the C-arm, 5 patients applied cone-beam CT technique, 5 patients used balloon dilatation of the stenotic segment, and the above factors were the main strategy methods for successful recatheterization. The success rate of DSA guided nasoenteric feeding tube placement will be greatly improved by adequate gastrointestinal decompression and drainage and other related preoperative preparation as well as good intraoperative application of cone-beam CT technique or combined application of balloon, gastroscope, stent and other technical means.

Influence of Nutritional Support Program on Gastrointestinal Function, Complication Rate, and Prognosis in Elderly Sufferers with CI.

To explore the effect of nutritional support program on gastrointestinal function, complication rate, and prognosis in elderly patients with cerebral infarction (CI), 200 elderly patients with CI from January 2020 to January 2021 are investigated in this study. The patients were randomly divided into a study set and a control group, with 100 cases in each set. All sets were given routine treatment, the control set was given parenteral nutrition support on a routine basis, and the study set was given enteral nutrition support on a routine basis. First, the clinical efficacy of the two sets after treatment was compared. Next, the constipation symptom score was adopted to compare the intestinal function of the two sets of patients before and after one month of treatment. The nutritional indicators, including serum albumin (ALB) and serum total protein (TP) levels, were compared between the two sets of patients before and after one month of treatment. Furthermore, the complications of the two sets of patients and the prognosis of the two groups of patients are analyzed. For elderly CI patients, enteral nutrition support therapy can significantly improve the clinical treatment effect, the gastrointestinal function, and nutritional index level. Also, it can reduce the incidence of complications and enhance the prognosis, survival rate, and quality of life.

A Single Nucleotide Mixture Enhances the Antitumor Activity of Molecular-Targeted Drugs Against Hepatocellular Carcinoma.

New strategies for molecular-targeted drug therapy for advanced hepatocellular carcinoma (HCC) ignore the contribution of the nutritional status of patients and nutritional support to improve physical status and immunity. We aimed to elucidate the role of a single nucleotide mixture (SNM) in the anti-tumor therapy of HCC, and to explore the importance of a SNM as adjuvant therapy for HCC. Compared with a lipid emulsion (commonly used nutritional supplement for HCC patients), the SNM could not induce metabolic abnormalities in HCC cells (Warburg effect), and did not affect expression of metabolic abnormality-related factors in HCC cells. The SNM could also attenuate the lymphocyte injury induced by antitumor drugs in vitro and in vivo, and promote the recruitment and survival of lymphocytes in HCC tissues. Using HCC models in SCID (server combined immune-deficiency) mice or BalB/c mice, the SNM had anti-tumor activity, and could significantly upregulate the antitumor activity of molecular-targeted drugs (tyrosine-kinase inhibitors [TKI] and immune-checkpoint inhibitors [ICI]) against HCC. We employed research models in vivo and in vitro to reveal the anti-tumor activity of the SNM on HCC. Our findings expand understanding of the SNM and contribute to HCC (especially nutritional support) therapy.

Acid-base disorders: A primer for clinicians.

An understanding of acid-base physiology is necessary for clinicians to recognize and correct problems that may negatively affect provision of nutrition support and drug therapy. An overview of acid-base physiology, the different acid-base disorders encountered in practice, a stepwise approach to evaluate arterial blood gases, and other key diagnostic tools helpful in formulating a safe and effective medical and nutrition plan are covered in this acid-base primer. Case scenarios are also provided for the application of principles and the development of clinical skills.

Implementation of a best-practice guideline: Early enteral nutrition in a neuroscience intensive care unit.

Current evidence suggests that early enteral nutrition is a best practice and leads to improved clinical outcomes. An evidence-based practice project was implemented in a busy neurointensive care unit in a midwestern tertiary care facility that was designed to improve care by implementing the early nutrition portion of Guidelines for the Provision and Assessment of Nutrition Support Therapy in the Adult Critically Ill Patient: Society of Critical Care Medicine and the American Society for Enteral and Parenteral Nutrition. The Registered Nurses' Association of Ontario's (RNAO) Toolkit: Implementation of Best Practice Guidelines (BPGs) was selected and followed to guide implementation and achieve optimal results. During a 90-day implementation period, this project resulted in a 100% improvement in early nutrition. Interventions included the use of a series of cards that reminded the team to order enteral nutrition and prepacked bundles of nasogastric tube supplies. The RNAO toolkit served as a structured and effective step-by-step methodology for the implementation of a BPG.

Significant Published Articles in 2021 for Pharmacy Nutrition Support Practice.

Purpose: The purpose of this article is to assist the pharmacist engaged in nutrition support therapy in staying current with pertinent literature. Methods: Several clinical pharmacists engaged in nutrition support therapy compiled a list of articles published in 2021 considered important to their clinical practice. The citation list was compiled into a single spreadsheet where the author participants were asked to assess whether the article was considered important to nutrition support pharmacy practice. A culled list of publications was then identified whereby at least 5 out of the 8 author participants considered the paper to be important. Guideline and consensus papers from professional organizations, important to practice but not ranked, were also included. Results: A total of 211 articles were identified; 8 from the primary literature were voted by the group to be of high importance. An additional 18 guidelines, position, recommendation, or consensus papers were also identified. The top-ranked articles from the primary literature were summarized and a narrative regarding its implications to pharmacy nutrition support practice were provided. Conclusion: We recommend that pharmacists engaged in nutrition support therapy be familiar with these articles as it pertains to their practice.

Optimising Outcomes in Non Small Cell Lung Cancer: Targeting Cancer Cachexia.

Lung cancer is the commonest malignancy worldwide and the leading cause of cancer death. Half of patients with lung cancer present with advanced disease. The number of systemic therapies including immunotherapy and targeted treatment are rapidly increasing. Despite this, the outcomes for many patients with locally advanced and advanced lung cancer are poor, as many patients are too unwell for treatment. One of the reasons patients with Non-Small Cell Lung Cancer are not fit for treatment is cancer cachexia, which is common (upto 75% of patients) in this group. This metabolic syndrome presents clinically as weight loss (muscle +/- fat), decreased physical function (patients less active) and anorexia on a background of systemic inflammation. Currently there is not an optimal management pathway for these patients, however, there is emerging data that multi-modal intervention including nutritional support, physical training and pharmacological therapy may have a role in treating cachexia. This review discusses assessment and intervention in cancer cachexia.

The GLIM Criteria Represent a More Appropriate Tool for Nutritional Assessment in Patients With Crohn's Disease.

BackgroundThe early recognition of malnutrition is essential for improving the prognosis of patients with Crohn's disease (CD). The Global Leadership Initiative on Malnutrition (GLIM) criteria represent a new consensus for the diagnosis of malnutrition but need to be validated in CD. The aims were to explore the related factors of malnutrition in CD and explore whether GLIM-positive patients who did not meet the Nutritional Risk Screening 2002 (NRS 2002) would benefit from nutritional treatment.MethodsThis study retrospectively enrolled patients with CD at the Gastroenterology Department of Xiangya Hospital Central South University between March 2020 and March 2021. After bioelectrical impedance analysis, all patients underwent nutritional screening and diagnosis using the NRS 2002 and GLIM criteria, respectively. Multivariable analysis was performed to evaluate risk factors related to malnutrition in patients with CD. A multivariable Cox hazard model was used to assess the association between nutritional therapy and prognostic outcomes.ResultsOf the 118 patients included, fifty were classified as having a high malnutrition risk according to the NRS 2002, while 76 were diagnosed with malnutrition by the GLIM criteria. Multivariate analysis showed that a high malnutrition risk was independently associated with the L4 phenotype [odds ratio (OR) (95% confidence interval (CI)) = 4.718 (1.108, 20.10), p = 0.036] and Crohn's Disease Activity Index (CDAI) [OR (95% CI) = 1.018 (1.007, 1.029), p = 0.002] based on the NRS 2002. The age at onset [OR (95% CI) = 0.828 (0.699, 0.980), p = 0.028] and CDAI [OR (95% CI) = 1.111 (1.034, 1.195), p = 0.004] were regarded as independent risk factors related to malnutrition, as determined by the GLIM criteria. Among 26 GLIM+/NRS− patients, significantly more patients who received nutritional support achieved 6-week remission than patients who did not (100 vs. 71.4%, p < 0.05). The 6-week remission risk in patients treated with nutrition therapy was more than 4-fold higher than those without nutritional therapy.ConclusionThe GLIM criteria could diagnose more malnourished patients with CD who are not positively screened by the NRS 2002, among whom nutritional support therapy would be beneficial for disease remission. The new criteria should be more appropriate for assessing the nutritional status of patients with CD.

Changes in the intestinal expression of drug metabolism-related genes in a piglet model of parenteral nutrition

BackgroundParenteral nutrition (PN) may serve as a nutritional supportive therapy accompanied by oral medication, but the effect of PN on intestinal expression of drug metabolism-related genes remains unknown.MethodsTwelve Bama piglets receiving PN for 14 days were used as in vivo model. Changes in intestinal drug metabolism-related genes were examined by proteomic analysis. Serum levels of fibroblast growth factor 19 (FGF19) were determined by ELISA, and the effect of FGF19 on the expression of drug metabolism-related genes was examined using murine ileum organoids.ResultsA total of 1063 differentially expressed proteins were identified in PN group. Of note, two drug transporters (Abcb1 and Abcc2) were significantly decreased in PN group, along with two glutathione-related drug-metabolizing enzymes, glutathione peroxidase (Gpx2) and glutathione S-transferase (Gsta1). Serum FGF19 levels were dramatically reduced in PN group. Treatment with recombinant FGF19 in vitro dose-dependently up-regulated the expression of Abcb1, Abcc2, Gpx2 and Gsta1 in organoids.ConclusionOur data indicated that intestinal drug metabolism-related genes were significantly dysregulated under PN, and some of the changed genes were attributed to gut-derived FGF19.

Adequacy of nutritional support in critically ill patients post implementation of nutritional protocols in surgical intensive care unit of a university hospital.

To evaluate improvement in nutrition support therapy after the implementation of nutritional protocols in critically ill surgical patients. The ambidirectional study was conducted at the surgical intensive care unit of Aga Khan University Hospital, Karachi, using an evidenced-based nutritional protocol. The pre-protocol retrospective data group A comprised patient records from July to September 2018, while the post-protocol prospective data group B related to the period between October and December 2018. Both data sets involved patients of either gender aged at least 18 years who needed admission to surgical intensive care unit and were unable to take oral nutrition for >2 days and remained under intensive care for up to seven days. Data was analysed using SPSS 21. Of the 65 patients, 30(46.2%) were in group A; 21(70%) males and 9(30%) females with mean age 40±16.55 years (range: 18-80 years). The remaining 35(53.8%) were in group B; 27(77%) males and 8(23%) females with mean age 48.66±17.7 years (range: 18-86 years). Nutritional screening indicated that 16(53.3%) patients in group A and 35(100%) in group B were at the risk of developing malnutrition. Patients receiving enteral nutrition within 24 hours of admission increased from 7(23.35%) in group A to 17 (48.3%) in group B. Overall, the amount of enterally administered calories increased from mean 321057±2495 kcal (29.6%) in group A to mean 384585±2343 (92.6%) in group B. The amount of protein administered increased from mean 622.2±148.7 kcal (14.7%) in group A to mean 549±125.48 kcal (67.1%) in group B. Implementation of nutritional protocol resulted in improved delivery of nutritional support in thesurgical intensive care unit.

Advances in nutritional support therapy for stroke prevention and treatment

As a serious disease of death and disability, stroke constitutes a serious threat to human health. Because of stroke patients often have high-risk factors of malnutrition such as dysphagia and autonomic eating disorder, the hospitalization time, mortality and disability rate of stroke patients increases. Nutritional therapy can effectively improve the malnutrition of patients, which are of great significance for the treatment and rehabilitation of stroke and the prevention of its complications. Nutrients are important components of nutrition therapy, and different ways of nutrition therapy directly affect the effect of treatment. This article summarizes effects of nutrients and different nutritional treatments on stroke prevention, morbidity and treatment, and provides a theoretical basis and new thinking for further reducing the incidence rate of stroke, improving the quality of life in patients and reducing the financial burden of society and family.
