Associations between Geriatric Nutrition Risk Index,bone mineral density and body composition in type 2 diabetes patients

BACKGROUND Type 2 diabetes mellitus(T2DM),a fast-growing issue in public health,is one of the most common chronic metabolic disorders in older individuals.Osteoporosis and sarcopenia are highly prevalent in T2DM patients and may result in fractures and disabilities.In people with T2DM,the association between nutrition,sarcopenia,and osteoporosis has rarely been explored.AIM To evaluate the connections among nutrition,bone mineral density(BMD)and body composition in patients with T2DM.METHODS We enrolled 689 patients with T2DM for this cross-sectional study.All patients underwent dual energy X-ray absorptiometry(DXA)examination and were categorized according to baseline Geriatric Nutritional Risk Index(GNRI)values calculated from serum albumin levels and body weight.The GNRI was used to evaluate nutritional status,and DXA was used to investigate BMD and body composition.Multivariate forward linear regression analysis was used to identify the factors associated with BMD and skeletal muscle mass index.RESULTS Of the total patients,394 were men and 295 were women.Compared with patients in tertile 1,those in tertile 3 who had a high GNRI tended to be younger and had lower HbA1c,higher BMD at all bone sites,and higher appendicular skeletal muscle index(ASMI).These important trends persisted even when the patients were divided into younger and older subgroups.The GNRI was positively related to ASMI(men:r=0.644,P<0.001;women:r=0.649,P<0.001),total body fat(men:r=0.453,P<0.001;women:r=0.557,P<0.001),BMD at all bone sites,lumbar spine(L1-L4)BMD(men:r=0.110,P=0.029;women:r=0.256,P<0.001),FN-BMD(men:r=0.293,P<0.001;women:r=0.273,P<0.001),and hip BMD(men:r=0.358,P<0.001;women:r=0.377,P<0.001).After adjustment for other clinical parameters,the GNRI was still significantly associated with BMD at the lumbar spine and femoral neck.Additionally,a low lean mass index and higherβ-collagen special sequence were associated with low BMD at all bone sites.Age was negatively correlated with ASMI,whereas weight was positively correlated with ASMI.CONCLUSION Poor nutrition,as indicated by a low GNRI,was associated with low levels of ASMI and BMD at all bone sites in T2DM patients.Using the GNRI to evaluate nutritional status and using DXA to investigate body composition in patients with T2DM is of value in assessing bone health and physical performance.

Actuality and underlying mechanisms of systemic immuneinflammation index and geriatric nutritional risk index prognostic value in hepatocellular carcinoma

This editorial contains comments on the article“Correlation between preoperative systemic immune inflammation index,nutritional risk index,and prognosis of radical resection of liver cancer”in a recent issue of the World Journal of Gastrointestinal Surgery.It pointed out the actuality and importance of the article and focused primarily on the underlying mechanisms making the systemic immuneinflammation index(SII)and geriatric nutritional risk index(GNRI)prediction features valuable.There are few publications on both SII and GNRI together in hepatocellular carcinoma(HCC)and patient prognosis after radical surgery.Neutrophils release cytokines,chemokines,and enzymes,degrade extracellular matrix,reduce cell adhesion,and create conditions for tumor cell invasion.Neutrophils promote the adhesion of tumor cells to endothelial cells,through physical anchoring.That results in the migration of tumor cells.Pro-angiogenic factors from platelets enhance tumor angiogenesis to meet tumor cell supply needs.Platelets can form a protective film on the surface of tumor cells.This allows avoiding blood flow damage as well as immune system attack.It also induces the epithelial-mesenchymal transformation of tumor cells that is critical for invasiveness.High SII is also associated with macro-and microvascular invasion and increased numbers of circulating tumor cells.A high GNRI was associated with significantly better progression-free and overall survival.HCC patients are a very special population that requires increased attention.SII and GNRI have significant survival prediction value in both palliative treatment and radical surgery settings.The underlying mechanisms of their possible predictive properties lie in the field of essential cancer features.Those features provide tumor nutrition,growth,and distribution throughout the body,such as vascular invasion.On the other hand,they are tied to the possibility of patients to resist tumor progression and development of complications in both postoperative and cancer-related settings.The article is of considerable interest.It would be helpful to continue the study follow-up to 2 years and longer.External validation of the data is needed.

Nutritional Screening Tools in Institutionalized People: A Case Study of Using Nutritional Risk Screening (NRS 2002) and Mini Nutritional Assessment (MNA)

Nutritional status expresses the physiological and nutritional needs to maintain the composition and adequate functioning of the organism. NRS 2002 and MNA protocols were applied to short-term institutionalized patients in Rio Verde (Brazil). Older adults and people with special needs of all ages, both sexes, regardless of possible pathology they may have, except if it causes contagion, were included, patients duly authorized by the person responsible for the institution and who were able to undergo evaluation. Thirty-eight patients from the institution were evaluated, of which ten were excluded from the research according to pre-established criteria. More than 50% of participants were male, with an overall average age of 63.43 years. The characteristics related to nutritional status by NRS 2002 and MNA showed that the risk of malnutrition and its absence are associated with a wide age range. The MNA presents a more nuanced nutritional risk classification, showing that even 61% of the 96% of participants who would be out of nutrition risk, according to the NRS 2002, are “at risk of malnutrition”. Applying the MNA can demonstrate more conservative results than the NRS 2002.

Malnutrition Assessed Using the Geriatric Nutritional Risk Index Is Associated with Preoperative Incidence of Deep Vein Thrombosis in Japanese Patients Undergoing Total Knee Arthroplasty

Purpose: Few studies have evaluated the association between malnutrition and the risk of preoperative deep vein thrombosis (DVT) in patients undergoing primary total joint arthroplasty. This study aimed to investigate the prevalence of preoperative DVT in Japanese patients undergoing total knee arthroplasty (TKA) and the importance of malnutrition in the risk of preoperative DVT. Methods: We retrospectively analyzed 394 patients admitted for primary TKA at our institution between January 2019 and December 2023. All patients scheduled for TKA at our institution had serum D-dimer levels measured preoperatively. Lower-limb ultrasonography was examined to confirm the presence of DVT in patients with D-dimer levels ≥ 1.0 µg/mL or who were considered to be at high risk of DVT by the treating physician. Based on the results of lower-limb ultrasonography, all patients were divided into the non-DVT and DVT groups. The incidence of and risk factors for preoperative DVT were investigated, as well as the correlation of DVT with the patient’s nutritional parameters. We used two representative tools for nutritional assessment: the Geriatric Nutritional Risk Index (GNRI) and Controlling Nutritional Status Score. Results: The mean age was 77.8 ± 6.9 years. Preoperative DVT was diagnosed in 57 of the 394 (14.5%) patients. Multivariate logistic regression analysis showed that advanced age and malnutrition status, assessed using the GNRI, were independent risk factors for preoperative DVT. Conclusion: A high incidence of preoperative DVT was observed in patients who underwent TKA. Malnutrition status, as assessed using the GNRI, increased the risk of preoperative DVT. Our findings suggest that clinicians should consider these factors when tailoring preventive strategies to mitigate DVT risk in patients undergoing TKA.

Correlation between preoperative systemic immune inflammation index, nutritional risk index, and prognosis of radical resection of liver cancer

BACKGROUND Radical surgery is the most commonly used treatment for hepatocellular carcinoma(HCC).However,the surgical effect remains not ideal,and prognostic evaluation is insufficient.Furthermore,clinical intervention is rife with uncertainty and not conducive to prolonging patient survival.AIM To explore correlations between the systemic immune inflammatory index(SII)and geriatric nutritional risk index(GNRI)and HCC operation prognosis.METHODS This retrospective study included and collected follow up data from 100 HCC.Kaplan–Meier survival curves were used to analyze the correlation between SII and GNRI scores and survival.SII and GNRI were calculated as follows:SII=neutrophil count×platelet count/lymphocyte count;GNRI=[1.489×albumin(g/L)+41.7×actual weight/ideal weight].We analyzed the predictive efficacy of the SII and GNRI in HCC patients using receiver operating characteristic(ROC)curves,and the relationships between the SII,GNRI,and survival rate using Kaplan–Meier survival curves.Cox regression analysis was utilized to analyze independent risk factors influencing prognosis.RESULTS After 1 year of follow-up,24 patients died and 76 survived.The area under the curve(AUC),sensitivity,specificity,and the optimal cutoff value of SII were 0.728(95%confidence interval:0.600-0.856),79.2%,63.2%,and 309.14,respectively.According to ROC curve analysis results for predicting postoperative death in HCC patients,the AUC of SII and GNRI combination was higher than that of SII or GNRI alone,and SII was higher than that of GNRI(P<0.05).The proportion of advanced differentiated tumors,tumor maximum diameter(5–10 cm,>10 cm),lymph node metastasis,and TNM stage III-IV in patients with SII>309.14 was higher than that in patients with SII≤309.14(P<0.05).The proportion of patients aged>70 years was higher in patients with GNRI≤98 than that in patients with GNRI>98(P<0.05).The 1-year survival rate of the SII>309.14 group(compared with the SII≤309.14 group)and GNRI≤98 group(compared with the GNRI>98 group)was lower(P<0.05).CONCLUSION The prognosis after radical resection of HCC is related to the SII and GNRI and poor in high SII or low GNRI patients.

Analysis of nutritional risk,skeletal muscle depletion,and lipid metabolism phenotype in acute radiation enteritis

BACKGROUND Radiation enteritis,which often occurs during radiation-induced acute intestinal symptoms(RIAIS),is the most common and important complication during radiotherapy for cervical cancer.RIAIS caused by abdominal and pelvic radiotherapy will affect nutrient intake,digestion,absorption,and metabolism,leading to malnutrition or poorer nutritional status.In patients with malignant tumors,malnutrition can adversely affect the curative effect and response of radiotherapy by reducing radiosensitivity,affecting the precision of radiotherapy placement and increasing the incidence of radiotherapy-related adverse reactions.AIM To analyze nutritional risk,skeletal muscle depletion,and lipid metabolism phenotype in acute radiation enteritis.METHODS Fifty patients with cervical cancer received external beam radiotherapy,and 15 patients received brachytherapy after external beam radiotherapy.Body weight,body composition parameters,nutritional risk screening(NRS)2002 score,and blood biochemical indices of patients with cervical cancer during periradiation were tested by a one-way repeated measures analysis of variance.Metabolomics analysis was used to identify characteristic lipid metabolism pathways.Clinical factors that affect linoleic acid changes were screened using the generalized evaluation equation.RESULTS Among the 50 patients,37 had RIAIS,including 34 patients with grade 1-2 RIAIS and 3 patients with grade 3 RIAIS.The NRS 2002 score of patients who underwent cervical cancer radiotherapy continued to increase during the periradiation period,and 42 patients who underwent cancer radiotherapy had nutritional deficits(NRS 2002 score≥3 points)at the end of radiotherapy.Correlation analyses revealed that body weight and body mass index changes were closely associated with body fat content(R2=0.64/0.51).The results of the univariate analysis showed that radiotherapy time,percentage reduction of serum albumin,and percentage reduction of serum prealbumin were the key factors affecting skeletal muscle exhaustion(P<0.05).Metabolomic analysis of fecal supernatants of cervical cancer patients during the periradiation period revealed the involvement of linoleic acid,cholic acid,arachidonic acid,and N-acetyl-L-benzene alanine in the metabolic pathway of linoleic acid.CONCLUSION Cervical cancer radiotherapy patients faced nutritional risks,decreased serum albumin synthesis,and increased risk of skeletal muscle exhaustion.Linoleic acid was a biomarker of high nutritional risk.

Triceps skinfold thickness trajectories and the risk of all-cause mortality:A prospective cohort study

BACKGROUND The measurement of triceps skinfold(TSF)thickness serves as a noninvasive metric for evaluating subcutaneous fat distribution.Despite its clinical utility,the TSF thickness trajectories and their correlation with overall mortality have not been thoroughly investigated.AIM To explore TSF thickness trajectories of Chinese adults and to examine their associations with all-cause mortality.METHODS This study encompassed a cohort of 14747 adults sourced from the China Health and Nutrition Survey.Latent class trajectory modeling was employed to identify distinct trajectories of TSF thickness.Subjects were classified into subgroups reflective of their respective TSF thickness trajectory.We utilized multivariate Cox regression analyses and mediation examinations to explore the link between TSF thickness trajectory and overall mortality,including contributory factors.RESULTS Upon adjustment for multiple confounding factors,we discerned that males in the‘Class 2:Thin-stable’and‘Class 3:Thin-moderate’TSF thickness trajectories exhibited a markedly reduced risk of mortality from all causes in comparison to the‘Class 1:Extremely thin’subgroup.In the mediation analyses,the Geriatric Nutritional Risk Index was found to be a partial intermediary in the relationship between TSF thickness trajectories and mortality.For females,a lower TSF thickness pattern was significantly predictive of elevated all-cause mortality risk exclusively within the non-elderly cohort.CONCLUSION In males and non-elderly females,lower TSF thickness trajectories are significantly predictive of heightened mortality risk,independent of single-point TSF thickness,body mass index,and waist circumference.

Prognostic impact of preoperative nutritional and immune inflammatory parameters on liver cancer

The immune response to tissue damage or infection involves inflammation,a multifaceted biological process distinguished by immune cell activation,mediator secretion,and immune cell recruitment to the site of injury.Several blood-based immune-inflammatory biomarkers with prognostic significance in malignancies have been identified.In this issue of the World Journal of Gastrointestinal Surgery,they examined the prognosis of liver cancer radical resection in relation to pre-operative systemic immune-inflammation and nutritional risk indices.Comparing older and younger individuals often reveals compromised nutritional and immu-nological statuses in the former.Therefore,performing preoperative evaluations of the nutritional status and immunity in geriatric patients is critical.In addition to being a primary treatment modality,radical resection is associated with a sig-nificant mortality rate following surgery.Insufficient dietary consump-tion and an elevated metabolic rate within tumor cells contribute to the increased proba-bility of malnutrition associated with the ailment,consequently leading to a sub-stantial deterioration in prognosis.Recent studies,reinforce the importance of nu-tritional and immune-inflammatory biomarkers.Prior to surgical intervention,geriatric nutritional risk and systemic immune-inflammatory indices should be prioritized,particularly in older patients with malignant diseases.

Malnutrition and Its Association with the Mortality of Patients with Femoral Intertrochanteric Fractures: A Retrospective Analysis of Japanese Patients

Background: The incidence of femoral intertrochanteric fractures in older adults is higher than that of femoral neck fractures;however, both conditions are often analyzed together as proximal femoral fractures. Considering the difference in treatment, postoperative complication, and mortality risk, these two fractures should be analyzed separately. This study aimed to analyze 1-year mortality and its risk factors in patients with surgically treated femoral intertrochanteric fractures. Methods: Consecutive patients with intertrochanteric fractures who underwent surgical interventions at our institution between January 2017 and December 2021 were retrospectively reviewed. A total of 238 patients were eligible for inclusion in this study. Patients’ demographic and clinical information were retrospectively collected. Patients were divided into the 1-year mortality (n = 16) and survival (n = 222) groups. The incidence of 1-year mortality and its independent risk factors were investigated using univariate and multivariate logistic regression analyses. Results: The mean age of patients was 85.6 ± 8.5 years. The 1-year mortality rate was 6.7% (16/238). Preoperative albumin level, the Geriatric Nutritional Risk Index (GNRI), and malnutrition status (GNRI p = 0.02, p = 0.02, and p = 0.0011, respectively). Multivariate analysis showed that malnutrition status (GNRI p = 0.035) was an independent risk factor for 1-year mortality. Conclusion: Malnutrition status assessed using GNRI (GNRI < 92) was an independent risk factor for 1-year mortality. Our findings suggest that GNRI may be an effective screening tool for predicting postoperative 1-year mortality of patients with surgically treated femoral intertrochanteric fractures.

Validation of nutritional risk index method against patientgenerated subjective global assessment in screening malnutrition in colorectal cancer patients

Objective：To validate malnutrition screening tool of nutrition risk index （NRI） against patent-generated subjective global assessment （PG-SGA） as a gold standard tool in colorectal cancer patients before radiotherapy.Methods：Nutritional status of 52 volunteer colorectal cancer patients with a mean age of 54.1±16.8 years who referred to radiotherapy center were assessed by PG-SGA （gold standard method） and NRI.Serum albumin levels of patients were determined by colorimetric method.A contingency table was used to determine the sensitivity,specificity,and predictive value of the NRI in screening patients at risk of malnutrition,in comparison with the PG-SGA in patients before radiotherapy.Results：The findings of PG-SGA and NRI showed that 52％ and 45％ of patients in our study were moderately or severely malnourished respectively.The NRI had a sensitivity of 66％ and a specificity of 60％ against PG-SGA.The positive predictive value was 64％ and the negative predicative value was 62％.The agreement between NRI and PG-SGA was statistically insignificant （kappa =0.267; P＞0.05）.Conclusions：The findings of present study showed that the prevalence of malnutrition was high in patients with colorectal cancer.Moreover,NRI method had low sensitivity and specificity in assessing nutritional status of patients with cancer.It seems that the combination of anthropometric,laboratory parameters and a subjective scoring system may be helpful tools in screening of malnutrition in cancer patients.

Analysis on Nutritional Risk Screening and Influencing Factors of Hospitalized Patients in Central Urban Area

Rational nutritional support shall be based on nutritional screening and nutritional assessment. This study is aimed to explore nutritional risk screening and its influencing factors of hospitalized patients in central urban area. It is helpful for the early detection of problems in nutritional supports, nutrition management and the implementation of intervention measures, which will contribute a lot to improving the patient＇s poor clinical outcome. A total of three tertiary medical institutions were enrolled in this study. From October 2015 to June 2016, 1202 hospitalized patients aged ≥18 years were enrolled in Nutrition Risk Screening 2002（NRS2002） for nutritional risk screening, including 8 cases who refused to participate, 5 cases of same-day surgery and 5 cases of coma. A single-factor chi-square test was performed on 312 patients with nutritional risk and 872 hospitalized patients without nutritional risk. Logistic regression analysis was performed with univariate analysis（P〈0.05）, to investigate the incidence of nutritional risk and influencing factors. The incidence of nutritional risk was 26.35% in the inpatients, 25.90% in male and 26.84% in female, respectively. The single-factor analysis showed that the age ≥60, sleeping disorder, fasting, intraoperative bleeding, the surgery in recent month, digestive diseases, metabolic diseases and endocrine system diseases had significant effects on nutritional risk（P〈0.05）. Having considered the above-mentioned factors as independent variables and nutritional risk（Y=1, N=0） as dependent variable, logistic regression analysis revealed that the age ≥60, fasting, sleeping disorders, the surgery in recent month and digestive diseases are hazardous factors for nutritional risk. Nutritional risk exists in hospitalized patients in central urban areas. Nutritional risk screening should be conducted for inpatients. Nutritional intervention programs should be formulated in consideration of those influencing factors, which enable to reduce the nutritional risk and to promote the rehabilitation of inpatients.

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

BACKGROUND: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).METHODS: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-variateadjusted 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.RESULTS: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.CONCLUSIONS: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.

Nutritional Risk Screening with NRS2002 among Hospitalized Cancer Patients in China

Objective The Nutritional Risk Screening 2002(NRS 2002)was used to assess the nutritional risk of hospitalized oncology patients in China.This study explored the factors affecting the risk of nutrition to provide a scientific basis for the assessment and treatment of malnutrition in oncology patients.Methods We used the NRS 2002 to evaluate the nutritional risk in 48,831 hospitalized cancer patients.Descriptive statistical methods were used to describe the general patient information.A Chi-squared test was applied to analyze the relationship between NRS 2002 scores and different demographic characteristics,and the NRS 2002 scores of cancer patients with different characteristics were compared by one-way ANOVA.Results Among 48,831 patients,43.3%were women and 57.7%were men,and 36.5%(17,802)of patients were at risk of nutrition(score≥3).The NRS 2002 score was the highest in leukemia patients(2.93±1.28).A one-way ANOVA revealed that the differences in NRS 2002 scores among patients of different gender,ages,TNM stages,education levels,occupations and areas of residence were statistically significant(P<0.001).Male patients had slightly higher NRS 2002 scores than females(2.33 vs.2.17).The lowest NRS 2002 scores were in patients aged 45-59(2.00±1.26)years and the highest scores were in patients aged≥70(2.76±1.43)years.The NRS 2002 score of patients receiving surgery was the highest(2.45±1.41),and patients receiving surgery plus radiotherapy/chemotherapy was the lowest(2.00±1.26).The risk of nutrition was highest in patients who were farmers(2.34±1.37 scores)and lowest in office staff(2.15±1.32 scores).Patients living in rural areas had the highest risk of nutrition(2.32±1.37 scores).There were significant differences in the NRS 2002 scores for different cancer sub-types for different ethnic groups(P<0.05),except for Zhuang individuals(P=0.124).The risk of nutrition was highest in Uyghur patients(3.35±1.33 scores)and lowest in Mongolians(2.04±1.37 scores).Conclusion More attention should be paid to people at high risk of nutrition,such as elderly patients,patients with a high TNM stage,patients receiving surgical treatment,and patients living in rural areas.Active nutritional interventions should be carried out to improve the nutritional status of malnourished patients.

The Role of the PNI and NLR in Nutritional Risk Screening and Assessment of Gastric Cancer Patients

Background The use of nutritional risk screening and assessment is becoming increasingly common in cancer patients.The Nutritional Risk Screening 2002(NRS 2002)is a nutritional risk screening programe with good utility.The patient generated-subjective global assessment(PG-SGA)is a method used to assess the nutritional status of cancer patients.The prognostic nutritional index(PNI)and neutrophil to lymphocyte ratio(NLR)are considered to be predictors of the prognosis following treatment for patients with a variety of cancers.However,the relationship between the PNI and NLR in the nutritional screening and assessment in patients with gastric cancer is unknown.Methods A retrospective analysis was performed on 378 patients with gastric cancer who underwent surgery at the First Affiliated Hospital of Guangxi Medical University from August 2019 to December 2020.NRS 2002 and PG-SGA were performed within 24 hours of admission,and indicators such as the serum albumin level,body mass index(BMI),PNI and NLR were measured.Results In the grouping based on the NRS2002,patients in the positive group(NRS 2002≥3)had a higher platelet value,a higher median NLR,and a lower PNI than those in the negative group(NRS 2002<3)(295.50±118.49×10^(9)/L vs.269.36±93.52×10^(9)/L,2.38 vs.1.77,42.36±5.96 vs.46.64±4.29).Based on the PG-SGA grouping,the serum albumin level and lymphocyte count were highest in the mild group(PG-SGA:score 2-3),(36.94±3.51 g/L and 1.91±0.7610^(9)/L)and lowest within the severe group(PG SGA score≥9)(34.09±4.18 g/L and 1.51±0.6410^(9)/L).The BMI was highest in the mild group(23.35±3.00 kg/m^(2))and lowest in the severe group(20.63±2.97 kg/m^(2)),and the PNI was also highest in the mild group(46.50±5.17)and lowest in the severe group(41.64±5.53).However,the NLR was lowest in the mild group(median 1.91)and highest in the severe group(median 2.44).Conclusion The PNI and NLR in gastric cancer patients are closely related to the results of the nutritional risk screening and assessment,suggesting that they may be useful to guide the nutritional interventions for gastric cancer patients.

The Effects of High Energy and Micronutrient Supplementation on Iron Status in Nutritionally at Risk Infants

The study assessed the effects of supplementary feeding over 180 consecutive days on iron status of infants and toddlers at six tea plantation in West Java, Indonesia. The design used was a clinical trial: two eohorts (i.e., 12 and 18 months old children) and three treatment groups (i.e., energy + micronutrient, micronutrient alone, and placebo) per cohort. Every day except Sunday, the infants attended day-care centers. Twenty four centers and 136 infants were selected. The infants were screened for weight and length and those meeting the criteria (i.e., <-1 SD of length-for-age, and between -1 and -2 SD of weight-for-length of the NCHS reference) were included. The experimental unit was the day-care centers (DCC), where each DCC was randomly assigned to one of the three treatment. As expected, groups of energy + micronutrient and micronutrient alone of the 12 months cohort experienced a significant upward shift in hemoglobin, ferritin and TS and a downward change in FEP, while the values for the group of placebo remain about the same as at base line. In the first 6 month of treatments, the ANOVA for each iron indicator yielded significant main effects of treatment (P<0.01) and for Hb with (P =0.059) on 12 months cohort. On the other hand, the main effects of treatment on hemoglobin, TS, ferritin and FEP were not significant for the 18 months cohort. In the second 6 month of treatments, the only significant of the treatment effect (P<0.01) was in serum ferritin on 18-month cohort. Under these circumstances, energy has a positive role in improving iron stores. It is likely that the equilibrium of hemoglobin and each iron indicators were reached in 6 months of treatment except ferritin still continued to increase up to 12 month. The effects of treatment on the improvement of iron status was stronger in 12 months than in 18 months

Clinical Significance of Preoperative Nutritional Risk Screening and Support in the Perioperative Period of Gastric Cancer Patients

Objective:To investigate the clinical value of using preoperative nutritional risk screening and support in gastric cancer patients.Methods:In this paper,70 gastric cancer patients selected from July 2017 to July 2020 treated in our hospital were grouped concerning the lottery method,and the reference group(n=35)used conventional nutritional support,while the experimental group(n=35)used preoperative dietary risk screening and support,comparing the clinical treatment differences between gastric cancer patients in the experimental group and the reference group.Results:After the intervention,IgA,IgM,IgG,serum albumin,complication rate,NRS score,hospitalization time and anal exhaust time of gastric cancer patients in the experimental group were compared with those in the reference group,P<0.05,and there was statistical validation analysis significance between the data indicators.P<0.05 for the comparison of IgA,IgM,IgG,serum albumin after the intervention and pre-intervention for gastric cancer patients in the experimental group and the reference group,with statistical validation analysis significance between the data indicators.Conclusion:Preoperative nutritional risk screening and support is of significant value in gastric cancer patients and can improve patients’nutritional status.

Correlation of dietary mineral intake and malnutrition in cancer patients:A multicenter cross-sectional study

Background:To examine the correlation between the dietary mineral intake and the nutritional status of patients suffering from malignan-cies.Methods:This multi-center cross-sectional study included a total of 866 patients with malignant tumors recruited from seven hospitals throughout China.The information of socio-demographic characteristics and biochemical indicators were obtained from electronic medical records of inpatients.Dietary data were collected using a 3-day 24-hour dietary recall questionnaire.The intake of energy,dietary calcium(Ca),phosphorus(P),potassium(K),sodium(Na),magnesium(Mg),iron(Fe),zinc(Zn),selenium(Se),copper(Cu)and manganese(Mn)were estimated according to the Chinese Food Composition Tables standard edition.The weight and height of patients were measured,and the body mass index(BMI)was calculated.Nutritional risk and malnutrition were assessed by the Nutritional Screening 2002(NRS 2002)and Global Leadership Initiative on Malnutrition(GLIM)diagnostic criteria.We used a multivariable logistic regression model to estimate the asso-ciations between dietary minerals and malnutrition.Results:The patients had an average age of 61.98(±15.49)years,and 40.6%(n=352)were female.Slightly less than half(44.5%)of the patients were at nutritional risk(NRS 2002≥3),and 32.7%were diagnosed with malnutrition(using the GUM criteria).Univariate analy-ses revealed that there was a statistically significant relationship between dietary mineral intake and the occurrence of nutritional risk(P<0.001).After adjusting the collinearity,we found that higher levels of P,Mn and Se intake were negatively associated with nutritional risk as-sessed by the NRS 2002 score.Moderate intake of Ca and high intake of Zn might also decrease the nutritional risk(Ca:OR,0.53,95%CI,0.32-0.88;Zn:OR,0.36,95%CI,0.19-0.68).However,no significant relationships were observed between any dietary mineral intake and malnutrition identified by the GUM criteria.Conclusions:Dietary minerals,especially P,Se,and Mn,may have a protective effect on the occurrence of nutritional risk in patients with malignant tumors.In addition,patients should maintain appropriate levels of Ca and Zn.

Effectiveness and safety of combined nimotuzumab and S-1 chemotherapy with concurrent radiotherapy for locally advanced esophageal cancer in malnourished and elderly patients:A prospective phaseⅡstudy

Objective:Definitive chemoradiotherapy(dCRT)is the standard treatment for unresectable locally advanced esophageal cancer.However,this treatment is associated with substantial toxicity,and most malnourished or elderly patients are unable to complete this therapy.Therefore,there is a need for a more suitable radiotherapy combination regimen for this population.This study was aimed to evaluate the efficacy and safety of a combination regimen comprising chemotherapy with nimotuzumab and S-1 and concurrent radiotherapy for patients with fragile locally advanced esophageal cancer with a high Nutritional Risk Screening 2002(NRS-2002)score.Methods:Eligible patients with unresectable esophageal carcinoma who had an NRS-2002 score of 2 or higher were enrolled.They were treated with S-1 and nimotuzumab with concurrent radiotherapy,followed by surgery or definitive radiotherapy.The primary endpoint was the locoregional control(LRC)rate.Results:A total of 55 patients who met the study criteria were enrolled.After completion of treatment,surgery was performed in 15 patients and radiotherapy was continued in 40 patients.The median follow-up period was 33.3[95%confidence interval(95%CI,31.4−35.1)]months.The LRC rate was 77.2%(95%CI,66.6%−89.4%)at 1 year in the entire population.The overall survival(OS)rate and event-free survival(EFS)rate were 57.5%and 51.5%at 3 years,respectively.Surgery was associated with better LRC[hazard ratio(HR)=0.16;95%CI,0.04−0.70;P=0.015],OS(HR=0.19;95%CI,0.04−0.80;P=0.024),and EFS(HR=0.25;95%CI,0.08−0.75;P=0.013).Most adverse events were of grade 1 or 2,and no severe adverse events occurred.Conclusions:For malnourished or elderly patients with locally advanced esophageal cancer,radiotherapy combined with nimotuzumab and S-1 is effective and has a good safety profile.

Comparison of different nutritional assessments in detecting malnutrition among gastric cancer patients

AIM: To evaluate the prevalence of preoperative and postoperative malnutrition and the relationships between objective and subjective nutritional assessment of gastric cancer patients. METHODS: From October 2005 to July 2006, we studied 80 patients with no evidence of recurrent disease and no loss to follow-up after curative surgery for gastric cancer. In this group, 9 patients underwent total gastrectomy and 71 patients subtotal gastrectomy. At admission, 6 and 12 mo after surgery, the patients were assessed on the subjective global assessment (SGA), nutritional risk screening (NRS-2002), nutritional risk index (NRI) and by anthropometric measurements and laboratory data. Differences between the independent groups were assessed with the Student's t test and oneway analysis of variance. Spearman's rank correlation coefficients were calculated to evaluate the association between the scores and variables. RESULTS: The prevalence of malnutrition at admissionwas 31% by SGA and 43% by NRS-2002. At admission, the anthropometric data were lower in the malnourished groups defined by the SGA and NRS-2002 assessments, but did not differ between the groups using the NRI assessment. Body weight (BW), body mass index (BMI), triceps skin fold and midarm circumference were significantly reduced, but the total lymphocyte count, albumin, protein, cholesterol and serum iron levels did not decrease during the postoperative period. Six months after surgery, there was a good correlation between the nutritional assessment tools (SGA and NRS-2002) and the other nutritional measurement tools (BW, BMI, and anthropometric measurements). However, 12 mo after surgery, most patients who were assessed as malnourished by SGA and NRS-2002 had returned to their preoperative status, although their BW, BMI, and anthropometric measurements still indicated a malnourished status. CONCLUSION: A combination of objective and subjective assessments is needed for the early detection of the nutritional status in case of gastric cancer patients after gastrectomy.
