ABSTRACT
Objective To investigate whether Royal Free Hospital Nutritional Prioritizing Tool (RFH-NPT) is more suitable than Nutritional Risk Screening 2002 (NRS-2002) in nutritional risk screening for patients with liver cirrhosis, as well as the applicability of subjective global assessment (SGA) in the nutritional assessment of patients with liver cirrhosis. Methods A total of 113 patients with liver cirrhosis who were hospitalized in Renmin Hospital of Wuhan University from August 2020 to June 2021 were enrolled. RFH-NPT and NRS-2002 were used for nutritional risk screening, and SGA was used for nutritional assessment. The results of these tools were compared with the Global Leadership Initiative on Malnutrition (GLIM) criteria, and sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated for the three tools. The receiver operating characteristic (ROC) curve was plotted and the area under the ROC curve (AUC) was calculated for each screening tool, and the association between nutritional status and short-term prognosis was analyzed. The independent samples t -test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The Spearman correlation analysis was used to analyze the correlation of GLIM criteria with NRS2002, RFH-NPT and SGA. Results According to the GLIM criteria, 69.9% of the patients were diagnosed with malnutrition, and RFH-NPT and NRS2002 screened out that 72.6% and 51.3%, respectively, of the patients had nutritional risk, while SGA assessment showed that 57.5% of the patients had malnutrition. Compared with NRS2002, RFH-NPT had a higher degree of correlation with the GLIM criteria ( r =0.764, P < 0.001), higher sensitivity (94.9%) and NPV (87.1%), and a better predictive value (AUC=0.872, 95% confidence interval [ CI ]: 0.786-0.957). Under the GLIM criteria, SGA had good specificity (88.2%) in the diagnosis of malnutrition in patients with liver cirrhosis, with fair sensitivity (77.2%), good correlation ( r =0.607, P < 0.001), and good predictive value (AUC=0.827, 95% CI : 0.744-0.911). Based on the GLIM criteria, SGA assessment, and RFH-NPT assessment, the patients with nutritional risk or malnutrition tended to have a longer length of hospital stay ( Z= -3.301, -2.812, and -3.813, all P < 0.05) and a higher rehospitalization rate ( χ 2 =3.957, 6.922, and 6.766, all P < 0.05). Based on the GLIM criteria and NRS2002 assessment, the patients with nutritional risk or malnutrition had a significant increase in mortality rate within 3 months ( χ 2 =4.511 and 0.776, both P < 0.05). Conclusion Under the GLIM criteria, RFH-NPT is more suitable than NRS2002 for nutritional risk screening of patients with liver cirrhosis, and SGA also has good applicability in nutritional assessment of patients with liver cirrhosis. In addition, GLIM criteria, SGA, and RFH-NPT are associated with the clinical outcome of patients.
ABSTRACT
Introdução: A American Society for Parenteral and Enteral Nutrition (ASPEN) recomenda que todos os pacientes admitidos em UTI sejam submetidos à triagem nutricional. A proposta é o uso de duas ferramentas, o Nutritional Risk Screening 2002 (NRS-2002) e o Nutrition Risk in the Critically Ill (NUTRIC), por meio das quais os pacientes são classificados como "em risco nutricional" e "risco nutricional alto". Objetivo: Comparar os riscos nutricionais detectados e analisar a concordância entre duas ferramentas de triagem nutricional recomendadas pela ASPEN (NUTRIC e NRS-2002). Métodos: Estudo de coorte retrospectivo realizado nas UTIs de dois centros hospitalares do Grupo Hospitalar Conceição (GHC), na região sul do Brasil. Foram incluídos pacientes adultos (≥ 18 anos) internados há mais de 24 horas nas UTIs. Os dados foram obtidos através de consulta ao prontuário dos pacientes, e coletados de maneira retrospectiva. Resultados: Foram incluídos no estudo 208 pacientes adultos internados nas UTIs de dois hospitais do GHC. Houve predominância do sexo masculino (>60%), e pacientes do centro 1 apresentaram idade mediana maior que o centro 2 [63 anos (50-73) vs 53 anos (39-63), respectivamente]. Pacientes do centro 1 apresentaram IMC marcadamente menor, e mais altos índices prognósticos APACHE e SOFA. O tempo de ventilação mecânica foi igual nos dois centros (mediana = 6 dias), e os pacientes do centro 1 evoluíram para óbito com maior frequência que os pacientes do centro 2 (55,6% vs 14,7%, respectivamente). A análise da concordância entre as ferramentas resultou em concordância fraca entre elas (Kappa < 0,4). Na amostra geral, quase metade dos pacientes foi classificada como em risco nutricional alto pelo NUTRIC, enquanto pelo NRS-2002, apenas e aproximadamente um terço. (AU)

OBJECTIVE@#The aim of this study was to determine whether low calf circumference (CC) could predict nutritional risk and the cutoff values of CC for predicting nutritional risk in hospitalized patients aged ⪖ 80 years.@*METHODS@#A total of 1,234 consecutive patients aged ⪖ 80 years were enrolled in this study. On admission, demographic data, CC, and laboratory parameters were obtained. Patients with Nutritional Risk Screening 2002 (NRS-2002) total score ⪖ 3 were considered as having nutritional risk.@*RESULTS@#CC values were significantly lower in patients with nutritional risk compared to those in patients without nutritional risk [27.00 (24.50-31.00) vs. 31.00 (29.00-33.50], P < 0.001]. CC was negatively correlated with age and nutritional risk scores. Logistic regression analysis of nutritional risk revealed that body mass index, albumin level, hemoglobin level, cerebral infarction, neoplasms, and CC (OR, 0.897; 95% confidence interval, 0.856-0.941; P < 0.001) were independent impact factors of nutritional risk. Nutritional risk scores increased with a decrease in CC. In men, the best CC cutoff value for predicting nutritional risk according to the NRS-2002 was 29.75 cm. In women, the cutoff value was 28.25 cm.@*CONCLUSION@#CC is a simple, noninvasive, and valid anthropometric measure to predict nutritional risk for hospitalized patients aged ⪖ 80 years.

<p><b>OBJECTIVE</b>The primary aim of the study was to compare two nutritional status evaluation tools: the Patient-Generated Subjective Global Assessment (PG-SGA) and Nutritional Risk Screening (NRS-2002). Using the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30 (EORTC QLQ-C30), the second aim was to provide constructive advice regarding the quality of life of patients with malignancy.</p><p><b>METHODS</b>This study enrolled 312 oncology patients and assessed their nutritional status and quality of life using the PG-SGA, NRS-2002, and EORTC QLQ-C30.</p><p><b>RESULTS</b>The data indicate that 6% of the cancer patients were well nourished. The SGA-A had a higher sensitivity (93.73%) but a poorer specificity (2.30%) than the NRS-2002 (69.30% and 25.00%, respectively) after comparison with albumin. There was a low negative correlation and a high similarity between the PG-SGA and NRS-2002 for evaluating nutritional status, and there was a significant difference in the median PG-SGA scores for each of the SGA classifications (P < 0.001). The SGA-C group showed the highest PG-SGA scores and lowest body mass index. The majority of the target population received 2 points for each item in our 11-item questionnaire from the EORTC QLQ-C30.</p><p><b>CONCLUSION</b>The data indicate that the PG-SGA is more useful and suitable for evaluating nutritional status than the NRS-2002. Additionally, early nutrition monitoring can prevent malnutrition and improve the quality of life of cancer patients.</p>
ABSTRACT
Objective:To evaluate the effect of M-POSSUM and NRS2002 in predicting the postoperative complications and mortality of abdominal surgery in general surgery.Methods:The M-POSSUM score and NRS2002 score of 121 patients undergoing abdominal major surgery in Department of general surgery were measured by continuous fixed-point sampling,and the receiver operating characteristic (ROC) curve was compared between the two methods.The levels of serum albumin,prealbumin and complications were recorded 1,3 and 7 days after operation.Results:The scores of M-POSSUM and NRS2002 in the complication group were significantly higher than those in the non complication group.The difference was statistically significant (P＜0.05).The scores of M-POSSUM and NRS2002 in the death group were significantly higher than those in the survival group(P＜0.05).The area under curve(AUC) of M-POSSUM,NRS2002 score and the combination of the two methods were 0.795,0.714 and 0.826 respectively.The AUC for predicting mortality were 0.904,0.871,and 0.935,respectively.Albumin and prealbumin were significantly lower than those before operation on 1 day,3 day and 7 day(P＜0.05).The values of albumin and prealbumin in the patients without complications increased significantly on the 7 day after surgery(P＜0.05).There was no significant difference between the patients with complications and the 3 days after operation(P＞0.05).Conclusion:M-POSSUM score and NRS2002 score can effectively predict the complications and mortality after general surgery.Patients with major abdominal surgery have higher nutritional risk,and albumin and prealbumin are significantly lower than those before operation,suggesting that the incidence of complications may increase.
ABSTRACT
Objective To investigate the situation about cognitive performance of critical care staffs in nutrition therapy for mechanical ventilated chronic obstructive pulmonary disease (COPD) patients in county hospitals.Methods A chart of questionnaire about nutrition therapy was formulated according to the current guidelines.Critical care staffs from 12 hospitals of county-level of Hang Zhou city were enrolled.The role of staffs in management of nutritional therapy for patients was observed to assess their cognitive performance and influence factors were analyzed according logistic analysis.Results A total of 137 staffs were enrolled.Almost all of the staffs thought that nutrition therapy for ventilated COPD patients was very important.About 90％ of the staffs never heard about the use of NRS2002 (nutritional risk screening 2002)to evaluation COPD patients but the rate of using it was higher among senior staffs (OR =1.08,95％ CI:1.01-1.16,P =0.04).Most of staffs assess the nutritional status of patients according to biomarkers and other methods.However,doctors might assess nutritional status more often according to their experience.The majority of staffs did choose enteral nutrition for patients especially seen in doctors and senior staffs (OR =3.10 and1.13,95％ CI:1.27-7.55 and 1.03-1.23,both P =0.01).For those without malnutrition,senior staffs did not choose parenteral nutrition (OR =0.14,95％ CI:0.04-0.57,P =0.01).Besides,senior staffs did not continue the enteral nutrition in patients with unstable haemodynamics (OR =1.10,95％ CI:1.03-1.16,P =0.002).Most of staffs considered that the head piece of bed was raised up to 30-45 degree and gastric residual volume monitoring was very important.However,compared with nurses,the cognitive performance of doctors was poorer (OR =0.39,95％ CI:0.18-0.83,P =0.01).Most of staffs thought that the nutrition therapy implementation checklist was necessary but it was used in only 20％ institutions.The understanding and demand for nutritional knowledge was more urgent among doctors than nurses (OR =3.13 and 5.33,95％ CI:1.45-6.75 and 1.13-25.02,P =0.004 and 0.03).Conclusions Nutrition therapy was important for ventilated COPD patients,but the staffs were not very familiar with nutritional knowledge.The cognitive performance of medical staffs was influenced by their profession and experience of practice.
ABSTRACT
Objective:To evaluate the application of PG-SGA,NRS 2002 and BIA in nutritional assessment and screening of patients with gynecologic cancers.Methods:118 patients were randomly selected.Nutritional status were evaluated by PG-SGA,NRS 2002 and BIA,and consistency between each tools were compared.Results:The prevalence of malnutrition or nutritional risk of patients were 64.4％ (PG-SGA),57.6％ (NRS 2002),and 33.9％ (BIA) respectively.In all patients,the consistency of PG-SGA and NRS 2002 was high (P ＜ 0.001),while there were not significantly consistent between BIA and PG-SGA,or between BIA and NRS 2002 (P ＜ 0.001).Conclusion:According to the evaluation of PG-SGA or NRS 2002 in gynecologic patients,the prevalence of malnutrition or nutritional risk is high,and these two scales are suitable for nutritional assessment and screening of gynecologic cancer patients,especially in ovarian cancer patients.In addition,BIA may be a promising tool to evaluate cervical cancer patients' nutritional status.
ABSTRACT
Numerosos estudios han demostrado que la desnutrición hospitalaria compromete la recuperación del paciente, prolonga el tiempo de internación y aumenta las probabilidades de infección y morbimortalidad. En Argentina la prevalencia de desnutrición hospitalaria es del 47% según el estudio AANEP 99. Se recomienda realizar una evaluación nutricional más exhaustiva en los individuos en riesgo para profundizar el diagnóstico y determinar un tratamiento precoz, adecuado a sus necesidades. Objetivo. Determinar el riesgo nutricional de los pacientes al ingreso hospitalario durante el periodo comprendido entre el 7 y el 20 de diciembre de 2015. Materiales y Métodos. Estudio descriptivo transversal que admitió sólo pacientes mayores de 14 años. Se utilizó el Nutritional Risk Screening (NRS 2002) como herramienta de recolección de datos. Resultados. Demostraron riesgo nutricional (puntaje ≥ 3 NRS 2002) veinticuatro (31,2%) de los setenta y siete pacientes valorados. Todos los pacientes admitidos en Unidades de Cuidados Críticos estaban en riesgo nutricional, situación que sólo correspondió a 23 % de los internados en Clínica Médica y en Cirugía General. Conclusión. La prevalencia de desnutrición intrahospitalaria en los hospitales modernos es equiparable a la detectada hace más de 50 años. Conocer el estado nutricional de los pacientes es fundamental para instaurar el tratamiento adecuado y optimizar la utilización de recursos orientándolos a los individuos que presenten características que denoten mayor riesgo

Os pacientes cirúrgicosdesnutridos possuem maior chance de apresentar complicaçõesdurante a internação hospitalar e elevado índice de morbidade emortalidade, sendo, portanto fundamental o monitoramento adequadodo estado nutricional.Objetivo: Identificar, por meio de revisão de literatura, a eficáciado método de triagem NRS 2002 em predizer desfechos clínicos empacientes cirúrgicos.Métodos: Foi realizada busca de artigos publicados no período de2003 a 2013, utilizando-se palavras-chaves em conformidade aosDescritores em Ciências da Saúde, nos idiomas inglês, português eespanhol. A seleção foi baseada nos títulos, resumos e descritores.Resultados: A alta taxa de prevalência de desnutrição no ambientehospitalar associa-se a um pior prognóstico, como maior tempode internação, maiores taxas de complicações infecciosas e não infecciosas,além da mortalidade. Dessa forma, é imperativo que essacondição seja detectada precocemente, a fim de se evitar tais desfechosnegativos, principalmente em pacientes cirúrgicos.Considerações finais: A triagem nutricional NRS 2002 permite aidentificação precoce e o tratamento da desnutrição, atenuando osefeitos adversos associados à desnutrição e melhorando o prognósticoclínico durante a internação.
Introduction: Nutritional Risk Screening (NRS 2002) was proposedto identify patients at nutritional risk who may benefit fromearly nutritional therapy. Malnourished surgical patients are morelkely to have complications during hospital stay and higher morbidityand mortality hospitalization and are therefore fundamentalto proper monitoring of nutritional status.Objective: To identify, through literature review, the effectivenessof NRS 2002 screening method for predicting clinical outcomes insurgical patients.Methods: A search was conducted for articles published in the period2003-2013, using keywords in accordance to Health SciencesDescriptors in English, Portuguese and Spanish languages . The selectionwas based on the titles, abstracts and keywords.Results: A high prevalence of malnutrition in hospitals is associatedwith a worse prognosis, longer hospitalization, higher rates ofinfectious and non-infectious complications, and mortality. Thus,it is imperative that this condition is detected early in order to avoidsuch negative outcomes, particularly in surgical patients.Conclusion: The nutritional screening NRS 2002 allows for theearly identification and treatment of malnutrition, mitigating theadverse effects associated with malnutrition and improving clinicaloutcomes during hospitalization.

Objective To explore the nutritional condition of primary liver cancer inpatients by means of nutrition risk screening 2002 (NRS2002) and mini nutritional assessment,and compare their feasibility.Methods A total of 80 cases of liver cancer patients hospitalized in Tianjin Third Central Hospital from August 2012 to March 2013 were collected.We investigated the incidence of malnutrition with the scales of NRS2002 and MNA.Comparative analysis of the relationship between the two methods and the traditional single index,liver function was conducted in order to find the more appropriate one for nutritional evaluation.Results NRS2002 got a 33.7％ nutrition risk incidence and MNA showed a 45.0％ risk rate.NRS2002 showed better correlation with traditional individual indicators than MNA.Conclusions Compared with MNA,NRS2002 is more reliable for nutritional assessment in primary liver cancer inpatients.
ABSTRACT
<b>Objective</b>: This study aimed to investigate the effect of nutritional status on estimated fentanyl absorption in cancer patients being treated with a fentanyl transdermal patch (FP), by measuring the residual fentanyl content in used patches. <b>Methods</b>: 24 adult Japanese inpatients receiving FP treatment for chronic cancer-related pain were enrolled. During FP application, the nutritional risk of the patients was measured using the Malnutrition Universal Screening Tool (MUST) and Nutritional Risk Screening 2002 (NRS 2002), both of which are nutrition screening tools used widely in Japan. We then classified the patients into low-, medium-, and high-risk groups according to the nutritional risk measured by MUST, and compared the transdermal fentanyl delivery efficiency (FE) between that groups. <b>Results</b>: The FE, which is estimated by the residual fentanyl content in used FPs collected from the patients, was found to be decreased in the high-risk group. According to NRS 2002, the mean transdermal fentanyl delivery efficiency in the high-risk group was significantly lower than that in the low-risk group. <b>Conclusion</b>: These results showed that changes in nutritional status affect FE, and that poor nutritional status might decrease transdermal fentanyl absorption in cancer patients.
ABSTRACT
Objective To investigate the nutritional risk,undemutrition,and nutrition support in inpatients with early and middle stage gastrointestinal cancer undergoing radical surgery in a tertiary hospital in Weifang,Shandong Province.Methods A total of 8390 inpatients who were treated in the departments of oncological surgery,enterohepatic surgery,and general surgery in our hospital were consecutively recorded from December 2010 to August 2011 and from November 2011 to October 2012.After 153 patients were excluded for hospital length of stay less than 24 hours,age less than 18 years old or more than 90 years old,obnubilation,and/or refusal to participate in the research,8237 patients were sampled.After patients who did not meet the scheduled diagnosis were excluded,300 pathology-confirmed patients with early or middle stage gastrointestinal cancer were enrolled.Nutritional Risk Screening 2002 (NRS 2002) was performed within the first 48 hours after admission and nutrition support was evaluated until the discharge.Results A total of 300 early and middle stage gastrointestinal cancer patients (141 cases of gastric cancer and 159 cases of colorectal carcinoma) who underwent radical surgery met the inclusion criteria.Among them 185 (61.7％) were at nutritional risk.The undernutrition rate was 12.3％ (37/300) if evaluated from the score of nutritional defect part of NRS 2002,and 10.0％ (20/300) if based on body mass index ＜18.5 kg/m2.Totally 165 patients (89.2％) at nutritional risk and 99 patients (86.1％) without nutritional risk received nutrition support.The average ratio of parenteral nutrition to enteral nutrition was 82:1.The intake of calories was (78.1±24.8) k1/(kg,d) [(18.6±5.9)kcal/(kg·d)] and that of nitrogen was (0.10±0.06) g/(kg · d),yielding a ratio of calories vs.nitrogen of (244 ± 164)∶1.Conclusions Inpatients with early and middle stage gastrointestinal cancer tend to have high nutritional risk.The undernutrition rate is 10％-12.3％ in this population.Meanwhile,the application of nutrition support should be further standardized,particularly for patients without nutritional risk.
ABSTRACT
Objective: To evaluate feasibility of using European Nutritional Risk Screening 2002(NRS2002) for nutritional status assessment in primary hospital.Methods: 799 patients were enrolled in this study.697 patients who were according NRS request were assessed using NRS method in hospitalization day.The patient whose NRS scores were higher than 3 were justified under nutritional risk.102 patients who were not according NRS request were assessed by exeamining the serum albumin(ALB) in the next day.The patients whose serum ALB was lower than 35 g/L were justified malnutrition.Results: There were 697 patients could be evaluated by NRS method.Body Mass Index(BMI) was lower than 18.5 in 159(22.8%) cases and NRS scores were ≥3 in 240 cases(34.4 %) among 697 cases.Serum albumin was lower than 35 g/L in 31 (30.4%) cases among 102 cases who could not be evaluated by NRS method because of incapable of standing up(66/102,64.7%) and ascites or hydrothorax(17/102,16.7%) and concomitance of above-mentioned causes(11/102,10.8%) and coma(8/102,7.8%).Conclusion: Assessment of nutritional status of hospitalized patients in primary hospital using NRS2002 method is feasible.The patients who could not be evaluated by NRS 2002 method can be assessed by assaying serum ALB.
ABSTRACT
Objective: To apply the NRS2002 to screen the nutritional status of preoperative patients and investigate the nutrition support in the perioperation and clinical outcomes. Methods: 127 selective operational cases(including general surgery,thoracic surgery,gynecology and orthopedic) were recruited to adopte the NRS2002 which issued by CESPN in 2006,and the nutrition support,energy and nutriment in the perioperation,complications,length of stay and drug costs were investigated. Result: 30.7% patients needed nutrition support,with general surgery(28.3%) being higher than thoracic surgery(2.4 %),gynecology(0%) and orthopedic(0%).The nutritional risk in elderly,carcinoma,abdominal operation patients were 18.1%,19.7% and 18.1% seperately,which was higher than others(P
