Validity of the Patient-Generated Subjective Global Assessment(PG SGA)in Colorectal Cancer Patients in China

Objective The patient-generated subjective global assessment(PG-SGA)is a nutritional assessment tool specially designed for cancer patients.This study tested the validity of the PG-SGA for the nutritional assessment of colorectal cancer(CRC)patients in China.Methods A total of 8,093 Chinese patients with any stage CRC were enrolled in this cross-sectional,observational study.Within the first 48 hours of admission,patients were evaluated using the PG-SGA,nutritional risk screening 2002(NRS 2002),Karnofsky Performance Status(KPS),and some anthropometric parameters,including the triceps skinfold thickness(TSF),mid-arm circumference(MAC),mid-arm muscle circumference(MAMC),hand grip strength(HGS),maximum left calf circumference(MLCC),and maximum right calf circumference(MRCC),among others.Spearman’s correlation test was performed to analyze item-total score correlations and correlations between the total PG-SGA score and other parameters or performance scores,further testing convergent validity.The discriminative ability of the PG-SGA was measured by comparing different characteristics between several nutritional groups.A principal component analysis was performed with selected parameters to evaluate the construct validity.Results The average total PG-SGA score of all patients was 5.69±4.46,and they had a median age of 59 years(interquartile range(IQR),51-67 years)and an average body mass index(BMI)of 22.57±3.29 kg/m^(2).The item-total correlations of the total PG-SGA score between the global PG-SGA rating(Spearman,r=0.94)and PG-SGA score(patient-generated)(Spearman,r=0.97)were strong.Significant correlations were also found between the total PG-SGA score and other nutritional screening tools,including the BMI(Spearman,r=-0.26),KPS(Spearman,r=-0.36),and NRS 2002(Spearman,r=-0.47).Well-nourished(41.2%),mildly or moderately malnourished(35.3%)and severely malnourished(23.5%)groups defined according to the PG-SGA had significantly different characteristics.Patients with a worse nutritional status tended to have a decreased BMI(well-nourished,23.32 kg/m^(2)vs.mildly or moderately malnourished,22.52 kg/m^(2)vs.severely malnourished,21.35 kg/m^(2);P<0.001),hemoglobin,body fat mass,muscle mass,protein mass,TSF,MAC,HGS,MAMC,and MLCC,and a dramatically increased C-reactive protein level.The Kaiser-Meyer-Olkin measure was>0.7,and the P value of Bartlett’s test of sphericity was<0.001.One component was extracted by the principal component analysis,and the analysis showed that the total PG-SGA score explained the total variances of 97.3%.Conclusion The PG-SGA is a valid tool for evaluating the nutritional status for Chinese CRC patients.

Combining the Patient-Generated Subjective Global Assessment (PGSGA) and Objective Nutrition Assessment Parameters Better Predicts Malnutrition in Elderly Patients with Colorectal Cancer

Background Malnutrition is common in colorectal cancer(CRC)patients,especially in elderly patients.The Patient-Generated Subjective Global Assessment(PG-SGA)is a widely used tool developed to detect malnutrition.The aim of this study was to compare the value of the PG-SGA and objective nutrition assessment parameters,in order to identify a better predictive index for malnutrition in elderly patients with CRC.Methods A total of 131 elderly patients(age≥60 years)with CRC were included and were evaluated for their individual nutritional status using the PG-SGA.Anthropometric and serological indicators were also assayed within 48 h of admission to the hospital.Body composition analysis was implemented by bioelectrical impedance analysis(BIA)instrument.The Chi-squared test,univariate and multivariate logistic regression analysis,or Spearman’s rank correlation analysis were used to determine the differences among the above indices and parameters with regard to predicting malnutrition.Results According to the PG-SGA score,the incidence of total malnutrition in elderly patients with CRC was 80.92%(PG-SGA score≥2),which increased with age.It was found that 28%of the patients with PG-SGA classification A(PG-SGA score 0-1)had a low fat-free mass index(FFMI).Compared with those with PG-SGA A,patients with PG-SGA C PG-SGA score≥9)showed an increased neutrophil to lymphocyte ratio(NLR)and an increased platelet and lymphocyte ratio(PLR)(median=1.78 VS.2.35,P=0.015 and median=108.8 VS.141.6,P=0.001,respectively).In terms of objective nutrition assessment parameters,severely malnourished CRC patients had significantly lower values of serum albumin(ALB),and retinol conjugated protein(RBP)than those who were well-nourished[(38.35±4.84)g/L VS.(40.56±3.44)g/L,P=0.039 and(30.31±15.83)mg/L VS.(39.01±11.95)mg/L,P=0.033,respectively].The Spearman’s rank correlation analysis showed that the PG-SGA findings had positive correlations with the NLR and PLR;while it had negative correlations with the FFMI,body mass index(BMI),ALB,prealbumin,and RBP.Conclusions In clinical practice,a comprehensive nutritional diagnosis,including the PG-SGA score and these objective indicators,can avoid the underdiagnosis of malnutrition,and is more suitable to detect malnutrition(as well as its causes)in elderly patients with CRC.

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.

Prospective study evaluating the value of subjective global assessment and national risk score 2002 for post-operative risk detection in living related donor liver transplant recipients

Background: Chronic liver disease may be associated with protein energy malnutrition. Those malnourished patients undergoing liver transplantation suffer great morbidities and even mortalities. Estimating the degree of malnutrition in patients with end stage liver disease is a difficult job, Subjective Global Assessment (SGA) and Nutritional Risk Score-2002 (NRS-2002) are among many tools that can give an overview for the nutritional status of the patients. Aim: To detect the efficacy and the predictive validity of SGA and NRS 2002 for post-operative risk detection for liver transplant patients. Patients & Methods: 30 recipients of end stage liver disease had undergone a nutritional assessment by SGA score & NRS-2002 score, to be compared with the parameters of outcome of post-operative liver transplantation (ALT, AST, INR, Bilirubin, time spent in ICU, hospital infective episodes & number of antibiotic courses). Results: Patients declared as malnourished by SGA and NRS-2002 had higher post operative ALT & AST value, more prolonged INR, spent more time at ICU and hospital, suffered from more infective episodes and had more antibiotic courses in a significant statistical manner. Conclusion: SGA and NRS-2002 could be useful, simple and dependable tools to be used for risk detection of post-operative morbidities after liver transplantation.

Subjective Global Assessment as a Pre-Operative Nutrition Status Screening Tool for Head and Neck Cancer Patients of a Tertiary Health Care Setting

Introduction: In India, 57% of patients with head and neck cancers are documented with nutritional compromise. Active nutritional support has been shown to improve outcomes and reduce the cost of treatment in severely malnourished patients. The assessment of nutritional status should be a priority when initiating medical nutrition therapy. We evaluated the agreement between Subjective and Objective evaluation of pre-operative nutrition status of head and neck cancer patients in a tertiary cancer centre. Methods: Two hundred and thirty seven head and neck cancer patients who underwent surgery were eligible. The patients included both males (147) and females (90) with age varying between 23 - 88 years. All patients were screened for pre-operative nutrition status objectively as well as subjectively. The association of pre-operative SGA scores (A, B and C) subjectively, and PNS score (0, 1, 2) objectively were tested for statistical significance. Results: The cancer sites included tongue in 82, buccal mucosa in 30, thyroid in 28, alveolus in 18, glottis in 10, RMT in 10, nasal cavity in 9, FOM in 8. The pre-operative nutrition status based on subjective scores are A in 156 (65.8%), B in 75 (32%) and C in 6 (2.5%). The objective parameters obtained on the basis of BMI, % weight loss, PNI and S. albumin values are PNS 0 in 161 (67.9%), PNS 1 in 71 (30%) and PNS 2 in 5 (2.1%) patients. As the kappa coefficient p-0.56, there is moderate agreement between the pre-operative nutrition status subjectively as well as objectively. Conclusion: Subjective global assessment is a simple and inexpensive way to screen the pre-operative nutrition status when compared to the other objective assessment tool. SGA has moderate agreement with expensive and complicated objective assessment tools. So it can be a reliable tool for assessing the pre-operative nutrition status.

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.

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.

Preliminary validation of Global Leadership Initiative on Malnutrition criteria in cancer patients:A cross-sectional study

Background:The Global Leadership Initiative on Malnutrition(GLIM)has been used in China since 2019.This study aimed to test the use of the GLIM criteria in Chinese cancer patients and to compare the diagnostic performance of the GLIM criteria with the Patient-Generated Subjective Global Assessment(PG-SGA)and modified PG-SGA(mPG-SGA). Methods:A total of 2,000 cancer patients were consecutively screened using the Nutritional Risk Screening 2002 instrument on ad-mission.Patients at nutritional risk(Nutritional Risk Screening 2002 score≥3)were enrolled to obtain the complete GLIM,PG-SGA,and mPG-SGA criteria.To evaluate the convergent validity,Spearman correlation analysis was used to compare the test-retest reliability of the GLIM criteria and its results with the scores of various nutritional tools and objective parameters.Kruskal-Wallis tests and χ2 tests were used to test the discriminant validity among groups with different nutritional status.We calculated the sensitivity,specificity,positive predictive value,and negative predictive value for the various tools. Results:There were 562 patients found to be at nutritional risk,accounting for 28.1%of all patients.One hundred seventy-four patients(8.7%)were diagnosed as moderately malnourished,and 333 patients(16.6%)were severely malnourished based on the PG-SGA.When assessed using the GLIM criteria,185 patients(9.3%)were diagnosed as moderately malnourished and 311 patients(15.5%)were severely malnourished.The content validity of the GLIM criteria was 95%,evaluated by 60 medical staff members.The test-retest reliability was good.For the diagnosis of malnutrition versus the PG-SGA,the sensitivity of the GLIM was"good"(90.5%;95%confidence interval[95%CI]=88.0%-93.1%),with a positive predictive value of 92.5%(95%CI=90.2%-94.9%),but the spec-ificity and negative predictive value were"poor."Similar results were obtained when the mPG-SGA was used as the criterion. Conclusions:Overall,this cross-sectional study suggests that the GLIM criteria comprise a valid and reliable tool to assess the nutri-tional status of Chinese cancer patients.

Comparison of two nutritional assessment methods in gastroenterology patients

AIM:To investigate and compare efficacy and differences in the nutritional status evaluation of gastroenterology patients by application of two methods:subjective global assessment(SGA) and nutritional risk index(NRI).METHODS:The investigation was performed on 299 hospitalized patients,aged 18-84 years(average life span 55.57 ± 12.84),with different gastrointe-stinal pathology,admitted to the Department of Gastroenterohepatology,Clinical and Hospital Center "Bezanijska Kosa" during a period of 180 d.All the patients,after being informed in detail about the study and signing a written consent,underwent nutritional status analysis,which included two different nutritional indices:SGA and NRI,anthropometric parameters,bioelectrical impedance analysis,and biochemical markers,within 24 h of admission.RESULTS:In our sample of 299 hospitalized patients,global malnutrition prevalence upon admission varied from 45.7% as assessed by the SGA to 63.9% by NRI.Two applied methods required different parameters for an adequate approach:glucose level(5.68 ± 1.06 mmol/L vs 4.83 ± 1.14 mmol/L,F = 10.63,P = 0.001);body mass index(26.03 ± 4.53 kg/m2 vs 18.17 ± 1.52 kg/m2,F = 58.36,P < 0.001);total body water(42.62 ± 7.98 kg vs 36.22 ± 9.32 kg,F = 7.95,P = 0.005);basal metabolic rate(1625.14 ± 304.91 kcal vs 1344.62 ± 219.08 kcal,F = 9.06,P = 0.003) were very important for SGA,and lymphocyte count was relevant for NRI:25.56% ± 8.94% vs 21.77% ± 10.08%,F = 11.55,P = 0.001.The number of malnourished patients rose with the length of hospital stay according to both nutritional indices.The discriminative function analysis(DFA) delineated the following parameters as important for prediction of nutritional status according to SGA assessment:concentration of albumins,level of proteins,SGA score and body weight.The DFA extracted MAMC,glucose level and NRI scores were variables of importance for the prediction of whether admitted patients would be classif ied as well or malnourished.CONCLUSION:SGA showed higher sensitivity to predictor factors.Assessment of nutritional status requires a multidimensional approach,which includes different clinical indices and various nutritional param eters.

Antituberculosis Drug-Induced Liver Injury: An Ignored Fact, Assessment of Frequency, Patterns, Severity and Risk Factors

Background/Aims: Antituberculosis drug-induced liver injury (TB DILI) is a frequent medical problem in Pakistan. Critical understanding of various aspects of TB DILI is not only important to manage liver injury but may also prevent unnecessary discontinuation of antituberculosis treatment. The study is aimed to determine the frequency, types, severity and patterns of TB DILI. Study further evaluates various risk factors of TB DILI. Materials and Methods: This is a prospective cohort study of two seventy-eight patients with the diagnosis of tuberculosis, where patients were followed during tuberculosis treatment. TB DILI was defined in accordance to international DILI expert working group. Results: Out of two seventy eight-patients, ninety-five (34.14%) had TB DILI. The most common pattern of TB DILI was hepatocellular (63.15%) followed by mixed (23.15%) and Cholestatic (13.68%). Most of the patients had mild DILI (43.15%) followed by moderate (30.52%), severe (20.01%) and very severe (5.26%). Age > 35 years, concomitant hepatotoxic drugs, extrapulmonary TB and malnutrition are important risk factors for TB DILI. Conclusion: All patterns of TB DILI with varying severity were present. Age > 35 years, malnutrition, extrapulmonary TB and concomitant use of hepatotoxic drugs were risk factors for TB DILI.

Nutritional Assessment of Gynecological Cancer Patients in China

Background Malnutrition is common among cancer patients,but few studies have evaluated the nutritional status among gynecological cancer patients in China.This study aimed to assess the nutritional status of women with gynecological cancer using the patient-generated subjective global assessment(PG-SGA).Methods Data for gynecological cancer patients treated at 44 tertiary hospitals were retrieved from a multicenter study on tumor nutrition.The R Software was used for statistical analyses.Univariate analyses of PG-SGA scores were performed using the Chi-squared test for categorical variables and the Wilcoxon-rank sum test or Kruskal-Wallis test for continuous variables,as appropriate.The significance level was 0.05.Results Data for 1962 women with three types of gynecological cancer(cervical,uterine and ovarian cancer)were used for the data analysis.The median PG-SGA score was 4(interquartile range,IQR:1,8),the median participants’age was 51(IQR:46,59)years old,and the patients had a median BMI of 22.9(IQR:20.7,25.4).The percentages of women who had a medical co-morbidity,or had undergone any radical resection,chemotherapy,or radiotherapy were approximately 27.7%,55.4%,52.5%,and 30.2%,respectively.The levels of serum albumin and high density lipoprotein cholesterol(HDL-C)were 40.1g/L(IQR:36.8,43.1)and 1.2mmol/L(IQR:1.0,1.5),respectively.The identified risk factors for malnutrition based on the PG-SGA score were age(0.05±0.01,p=0.002),BMI(-0.34±0.04,p<0.001),having a medical co-morbidity(0.95±0.33,p=0.004),receiving radiotherapy(1.52±0.31,p<0.001),the serum albumin level(-0.18±0.03,p<0.001),and the HDL-C(-1.12±0.35,p=0.001)as indicated by a linear regression analysis.Conclusions A higher PG-SGA score is positively associated with the age of the patient,having a medical co-morbidity,and receiving radiotherapy,and is negatively related to the patients’BMI and serum albumin and HDL-C levels.
