Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tumor patient nutrition assessment algorithm, in particular to a tumor patient nutrition risk assessment system and method for informatization planning. BACKGROUND

[0002] In the field of medical nutrition, the nutrition management of tumor patients is particularly important due to their special metabolic conditions and treatment needs. Traditional nutrition risk assessment methods mainly rely on clinical indicators such as body weight changes, muscle mass assessment, and dietary records. However, these methods often lack sensitivity and specificity, making it difficult to identify potential nutritional problems early, resulting in poor timing and effectiveness of nutritional intervention. With the rapid development of metabolomics technology, its application in disease diagnosis and treatment has gradually expanded, providing a new perspective and tool for precision medicine. Metabolomics, as a system biology technology, can reveal the metabolic state and potential biomarkers by analyzing the composition and changes of metabolites in the body. Unlike traditional single indicator analysis, metabolomics provides comprehensive metabolic information, bringing unprecedented possibilities for identifying metabolic characteristics of complex diseases. However, the application of metabolomics in the nutrition risk assessment of tumor patients is still in its early stages, lacking systematic evaluation methods and standardized analysis processes. Tumor patients often face malnutrition, muscle atrophy, and nutritional disorders during the remission period due to high metabolic demands during tumor proliferation and side effects of anticancer treatment. These nutrition-related complications not only affect the quality of life of patients, but also weaken their immune system and reduce treatment effectiveness.

[0003] Therefore, the present application aims to provide a nutrition risk assessment method for tumor patients for informatization planning, which realizes the precise assessment of the nutritional status of tumor patients by integrating advanced metabolite detection technology and intelligent data analysis methods. SUMMARY

[0004] The purpose of the present application is to provide a nutrition risk assessment method and system for tumor patients for informatization planning, which comprehensively analyzes the tumor growth changes, physical changes, and intake and metabolism of nutrients of patients from multiple dimensions, can scientifically evaluate the effectiveness of nutritional intervention, and give effective nutrition risk warning.

[0005] In order to achieve the above purpose, the present application provides a nutrition risk assessment system and method for tumor patients for informatization planning. It includes the following specific steps:

[0006] S1, obtaining the tumor growth changes and physical growth changes of the tumor patient, and simultaneously obtaining the content of nutrients ingested and metabolized by the patient;

[0007] S2, evaluate the patient's body abnormality during the nutrition intervention process by the tumor growth change and the physical growth change of the tumor patient;

[0008] S3, evaluate the patient's metabolism abnormality during the nutrition intervention process by the intake and metabolism of the patient's nutrient content;

[0009] S4, analyze the effect of the nutrition intervention process based on the patient's body abnormality and the patient's metabolism abnormality evaluation results;

[0010] S5, determine whether nutrition risk warning is needed according to the nutrition intervention effect.

[0011] Further, in step S1, the tumor growth change of the tumor patient includes the size volume change of the tumor, the intake nutrient content of the patient includes protein, heat, carbohydrate and vitamin, and the metabolism nutrient content includes the nutrient content in excretion and blood.

[0012] Further, in step S1, it also includes:

[0015] S103, obtain the standardized tumor volume abnormality and the standardized physical change abnormality, and obtain the patient's body nutrition abnormality during the nutrition intervention process by comparing the standardized physical change abnormality with the standardized tumor volume abnormality.

[0016] Further, in step S2, obtain the intake nutrient content data of the patient, and perform intake nutrition abnormality evaluation based on the comparison between the intake nutrient content data of the patient and the standard content. The intake nutrition abnormality evaluation calculation formula is:

[0017]

[0018] Wherein, D is the type of intake nutrient, sa is the influence weight of the a-th type of intake nutrient in the nutrition intervention process, ca is the amount of the a-th type of intake nutrient in the nutrition intervention process, and cam is the average amount of the a-th type of intake nutrient required to be taken by the normal human body.

[0019] Further, in step S300, the content of the corresponding nutrient substance metabolized by the patient is obtained, and based on comparison of the content of the corresponding nutrient substance metabolized by the patient with the normal content of the corresponding nutrient substance metabolized by the intake nutrient substance, an abnormal metabolism evaluation is performed, wherein the abnormal metabolism evaluation calculation formula is:

[0020]

[0021] wherein B is the type of the metabolized nutrient substance, wb is the influence weight of the bth type of the metabolized nutrient substance, fb is the content data of the bth type of the metabolized nutrient substance of the patient, and fbm is the normal content data of the bth type of the metabolized nutrient substance corresponding to the intake nutrient substance of the patient.

[0022] Further, in step S4, the abnormal metabolism evaluation result of the nutrition intervention period is divided by the intake nutrition abnormal evaluation result, and after averaging, the nutrition intervention period patient metabolism abnormality is obtained, and after dividing by the patient metabolism abnormality of the corresponding nutrition intervention period before the period, the nutrition intervention process effect is obtained.

[0023] Further, in step S5, whether to perform nutrition risk warning is judged according to the nutrition intervention process effect, wherein if the obtained nutrition intervention process effect is greater than or equal to the set effect threshold value, it is indicated that the nutrition intervention is effective, and no nutrition risk warning is performed, and if the obtained nutrition intervention process effect is less than the set effect threshold value, it is indicated that the nutrition intervention is ineffective, and nutrition risk warning is performed.

[0042] Example 1

[0043] To address the lack of systematic assessment methods and standardized analytical procedures for the application of metabolomics in nutritional risk assessment of cancer patients, the following issues remain. Figure 1 - Figure 3 As shown, the method for nutritional risk assessment of cancer patients for information-based planning provided by embodiments of the present invention includes the following specific steps:

[0044] S1. Obtain information on tumor growth and physical changes in cancer patients, as well as the content of nutrients ingested and metabolized by the patients.

[0045] In this embodiment, the changes in tumor growth of cancer patients include changes in tumor size and volume; changes in physical condition include data reflecting the patient's physical condition such as weight, muscle mass, and physical fitness; and the content of nutrients ingested by the patient includes energy information contained in the nutrient intake information, including protein, calories, carbohydrates, and vitamins.

[0046] The content of metabolized nutrients includes information on the nutrient content in excrement and blood, including carbohydrate metabolism: glucose, lactic acid, pyruvate, etc.; lipid metabolism: free fatty acids, triglycerides, etc.; protein metabolism: branched-chain amino acids (BCAAs), glutamine, etc.; energy metabolism: metabolites such as ATP, NAD+, NADH, etc.; the levels of essential amino acids (such as leucine and isoleucine) and non-essential amino acids (such as glutamine) in the blood; and glutamine and carbohydrate metabolites in urine.

[0047] It should be noted that the various data collected in this embodiment are all collected using existing technology acquisition terminals, such as various component acquisition instruments, which will not be described in detail here.

[0048] S2. Assess abnormal changes in the patient's physical condition during nutritional intervention by observing changes in tumor growth and physical condition.

[0049] In this embodiment, assessing abnormal changes in a patient's physical condition during nutritional intervention based on changes in tumor growth and physical constitution includes the following specific steps:

[0050] S21. Obtain the changes in tumor size and volume during the nutritional intervention period, and perform abnormal tumor change analysis based on the changes in tumor size and volume during the nutritional intervention period.

[0051] The analysis of abnormal tumor changes includes the following specific steps:

[0052] The changes in tumor size and volume during the nutritional intervention period are obtained. Since larger tumors consume more nutrients, and tumor growth also leads to increased nutrient consumption, this embodiment obtains the changes in tumor size and volume and the average tumor size during the nutritional intervention period. Weighted summation and data standardization are then performed to obtain the tumor volume anomaly during the nutritional intervention period. The formula for calculating the tumor volume anomaly can be:

[0053]

[0054] in, The weighting is based on the proportion of volume change. Vm represents the change in tumor size and volume during the nutritional intervention period, Vmx represents the safe amount of change in tumor size and volume during the nutritional intervention period, Vc represents the average size of the tumor, and Vcx represents the safe amount of the average size of the tumor.

[0055] S22. Obtain the patient's physical growth changes during the nutritional intervention period, and compare these changes with normal physical condition to identify abnormalities in physical condition during the nutritional intervention period. The formula for calculating abnormal physical changes is as follows:

[0056]

[0057] Where n represents the type of physical characteristic, cj represents the degree of influence of the j-th physical characteristic on the overall physical condition, zjc represents the real-time data of the j-th physical characteristic during the intervention period, zjk represents the data of the j-th physical characteristic at the beginning of the intervention period, and zjm represents the median of the safe range of the j-th physical characteristic. The safe range of physical characteristics is the average range of the corresponding physical characteristics of normal individuals, which is detailed in existing health books.

[0058] S23. Obtain standardized abnormal tumor volume and standardized abnormal body constitution. Compare the standardized abnormal body constitution with the standardized abnormal tumor volume to determine the patient's nutritional abnormalities during nutritional intervention. The formula for calculating the patient's nutritional abnormalities is as follows:

[0059] Among them, Tzm is the standard value of abnormal changes in physical condition, and pvm is the standard value of abnormal volume. In the above steps, the abnormal changes in physical condition caused by the standardized tumor volume abnormality during the nutritional intervention cycle are compared with the actual abnormal changes in physical condition to obtain the abnormal nutritional absorption of the patient's body.

[0060] S3. Assess patients' metabolic abnormalities during nutritional intervention by measuring the levels of nutrients ingested and metabolized by the patients.

[0061] It should be noted that the various set parameters in this embodiment (including various values ​​and thresholds that cannot be collected by the acquisition terminal) are obtained as follows: by evaluating the changes in tumor growth and physical condition of historical cancer patients, as well as the content of nutrients ingested and metabolized by patients, the effects of the nutritional intervention process corresponding to historical data are obtained in each step of this embodiment. At the same time, medical experts are hired to judge whether the effects of the nutritional intervention process based on these historical data are qualified. The evaluation results and judgment results are then imported into the fitting software, and the values ​​of each set parameter that meet the maximum accuracy of the judgment result are output.

[0062] In this embodiment, assessing the metabolic abnormalities of patients during nutritional intervention by measuring the levels of nutrients ingested and metabolized by the patients includes the following specific steps:

[0063] S31. Obtain data on the nutrient content ingested by the patient. Based on the comparison between the patient's nutrient content data and the standard content, conduct an assessment of abnormal nutrient intake. The formula for calculating the assessment of abnormal nutrient intake is as follows:

[0064]

[0065] Where D represents the type of nutrient ingested, sa represents the influence weight of the a-th type of nutrient ingested during the nutritional intervention process, ca represents the amount of the a-th type of nutrient ingested during the nutritional intervention process, and cam represents the average amount of the a-th type of nutrient that a normal human body needs to ingest.

[0066] S32. Obtain the content of corresponding nutrients metabolized by the patient. Based on the comparison between the data of corresponding nutrient content metabolized by the patient and the normal content data of nutrient content metabolized from corresponding ingested nutrients, conduct an assessment of metabolic impact abnormalities. The calculation formula for the assessment of metabolic impact abnormalities is the same as the calculation formula for the assessment of nutrient intake abnormalities, namely:

[0067]

[0068] Wherein, B represents the type of nutrient metabolized, wb represents the influence weight of the b-th type of nutrient metabolized, fb represents the content of the b-th type of nutrient metabolized by the patient, and fbm represents the normal content of the b-th type of nutrient metabolized by the corresponding nutrient ingested by the patient.

[0069] S33. The metabolic abnormality of patients in the corresponding nutritional intervention period is obtained by averaging the results of the metabolic impact abnormality assessment of the corresponding nutritional intervention period by dividing the results of the standardized nutritional intake abnormality assessment by the results of the corresponding nutritional intervention period. The metabolic effect of nutritional intervention is obtained by dividing the results of the metabolic abnormality of patients in the previous period by the results of the corresponding nutritional intervention period and taking the reciprocal.

[0070] It should be noted that since the composition of ingested nutrients has a direct impact on the judgment of metabolic abnormalities, and the influence of abnormal nutrient composition on the judgment of metabolic abnormalities needs to be removed here, the metabolic abnormality assessment result is divided by the standardized nutrient intake abnormality assessment result. The standardized nutrient intake abnormality assessment result is to prevent the nutrient intake abnormality assessment result from being 0. Therefore, the standardization process here can be to take the nutrient intake abnormality assessment result as a power of the natural constant e.

[0071] S4. Analyze the effectiveness of nutritional intervention based on the patient's abnormal physical changes and the results of the assessment of the patient's metabolic abnormalities.

[0072] In this embodiment, the analysis of the effectiveness of nutritional intervention based on the patient's abnormal physical changes and the results of the assessment of the patient's metabolic abnormalities includes the following specific contents:

[0073] Obtain the calculated nutritional intervention cycle's metabolic effect and the patient's nutritional abnormality analysis results. Take the reciprocal of the obtained patient nutritional abnormality analysis results and sum them with the nutritional intervention cycle's metabolic effect to obtain the nutritional intervention process effect.

[0074] S5. Determine whether nutritional risk warning is needed based on the effects of nutritional intervention;

[0075] In this embodiment, determining whether a nutritional risk warning is needed based on the effect of nutritional intervention includes the following specific aspects: if the effect of the obtained nutritional intervention process is greater than or equal to the set effect threshold, it indicates that the nutritional intervention is effective and no nutritional risk warning is issued; if the effect of the obtained nutritional intervention process is less than the set effect threshold, it indicates that the nutritional intervention is ineffective and a nutritional risk warning is issued.
