Skeletal muscle density as a new predictor of abdominal infection in abdominal trauma patients

Background and aimsSkeletal muscle density (SMD) is a valuable prognostic indicator in various conditions such as cancer, liver cirrhosis. Yet, the connection between SMD and intra-abdominal infection in individuals who have suffered abdominal injuries is still unclear. The purpose of this research is to examine how well SMD can predict intra-abdominal infection in patients who have suffered abdominal trauma. MethodsParticipants with abdominal injuries were included in this research from January 2015 to April 2023. Based on the sex-specific cut off values of SMD, the entire population was split into two categories. Prognostic factors were identified through logistic regression analysis. ROC was used to assess the predictive accuracy of SMD and its combinations with other biomarkers for clinical outcomes. ResultsA total of 220 patients were ultimately included in the study. Patients in the group with low SMD exhibited a higher incidence of intra-abdominal infection, longer hospital stays, and increased hospital costs. In patients with abdominal trauma, low SMD was identified as a significant independent predictor of intra-abdominal infection (OR 2.397; 95% CI 1.117- 5.141, p = 0.025). Low SMD had a higher area under the curve (AUC) in ROC analysis compared to TRF, NRS2002 score, and APACHEII score for predicting intra-abdominal infection (AUC 0.70, 95% CI 0.61-0.78, p = 0.002). Moreover, low SMD showed associations with clinical outcomes such as hospital stay length and costs (p < 0.01). ConclusionsLow SMD is recognized as an independent risk factor for predicting intra-abdominal infections in this patient population. Notably, SMD is emerging as a novel predictor of abdominal infections in patients with abdominal trauma.

Nutritional status of patients with gastrointestinal cancers and analysis of factors for postoperative infections.

Patients with gastrointestinal cancer have a higher risk of malnutrition and postoperative infection. To investigate the nutritional status of patients with gastrointestinal cancers and factors for postoperative infections. Based on the nutritional risk status, 294 patients with gastrointestinal tumours were divided into a nutritional risk group and a non-nutritional risk group, and the differences between the two groups were compared. Among the included patients, 128 were at preoperative nutritional risk (43.54%); there were significant differences between the two groups in terms of age (66.25 ± 11.73 vs. 58.36 ± 10.41 years, P < 0.001), percentage of gastric cancers (39.84% vs. 28.92%, P = 0.049), percentage of stage IV tumours (60.16% vs. 45.18%, P = 0.011), total protein (64.90 ± 6.82 vs. 67.21 ± 7.41g/L, P = 0.007), albumin (38.32 ± 4.74 vs. 41.61 ± 5.10g/L, P < 0.001) and haemoglobin (112.72 ± 22.63 vs. 125.11 ± 22.79g/L, P < 0.001). Multivariate logistic regression analysis showed that risk factors for postoperative infections in patients included age ≥ 60 years (odds ratio [OR] = 2.266 95%CI = 1.357-4.134), Nutrition Risk Screening (NRS)-2002 score ≥ 3 (OR = 2.183, 95%CI = 1.218-4.102), alcohol history (OR = 2.505, 95%CI = 1.370-4.683), comorbid diabetes mellitus (OR = 2.110, 95%CI = 1.381-4.023) and surgical time ≥ 6h (OR = 2.446, 95%CI = 1.359-4.758). Patients with gastrointestinal cancers are at high incidence of preoperative nutritional risk, and those with an NRS-2002 score of > 3, history of alcohol consumption and surgical time of > 6h have a higher risk of postoperative infections.

Predictive value and model construction of preoperative nutritional indexes for postoperative leakage in gastric cancer

Objective: We aimed to explore the predictive significance of the nutritional indexes in the occurrence of postoperative leakage after gastrectomy, aiming to develop and validate a predictive nomogram for assessing the risk of these complications.Methods: Patients undergoing radical gastrectomy for gastric cancer were studied, using data from The Sixth Affiliated Hospital of Sun Yat-sen University (2019-2022, n=1075) for nomogram development and an external cohort from Sun Yat-sen University Cancer Center (2022, n=286) for validation. The model, focusing on postoperative leakage, was constructed through univariate and backward stepwise regression. The performance of nomogram was assessed using the receiver operating characteristic (ROC) curve, calibration plots, decision curve analysis (DCA), and clinical impact curves (CIC).Results: The incidence rates of postoperative leakage were 6.51% in the training cohort and 6.71% in the external validation cohort, respectively. The nomogram effectively identifies critical factors influencing postoperative leakage risk, including NRS-2002 score, SFMAI, VSR, blood loss, intraoperative time, type of reconstruction, and Lauren type. The areas under the curve (AUC) for the development and external validation cohorts were 0.763 and 0.761, respectively, demonstrating acceptable predictive accuracy. The validation study showed the nomogram's satisfactory calibration, and both DCA and CIC confirmed its significant clinical utility.Conclusions: The nomogram offers an efficient and precise tool for initial screening, effectively identifying individuals at elevated risk for postoperative leakage.

Nutritional Risk, Nutritional Status and Some Biochemical Parameters In Adult Burn Patients in Burn Intensive Care Unit: A Prospective Study

Nutritional therapy is very important in burn patients and plays a role in the prevention and treatment of malnutrition. Therefore, it is necessary to assess nutritional status, prevent or minimize nutritional problems, and monitor nutritional therapy. This study was conducted to determine the nutritional risk, nutritional status and biochemical parameters of adult burn patients in the burn intensive care unit. The 59 patients (women: 16, men: 43) between the ages of 19-64 were included in the study. Parameters such as NRS-2002 (admission and discharge), dietary intake, nutritional support status, serum albumin, and total protein (admission and discharge) were evaluated to determine the nutritional risk and nutritional status of the patients. In addition, body weight, mid-upper arm circumference, and triceps skinfold thickness were measured and body mass index was calculated (admission and discharge). The duration of hospitalization and burn percentage of men patients were higher than women (P &lt; 0.05). A significant decreases were determined in the mean body weight, body mass index, and triceps skinfold thickness of men patients at discharge compared to admission (P &lt; 0.05). In men patients, a statistically significant difference was found in serum albumin, hemoglobin, and hematocrit values between admission and discharge (P &lt; 0.05). A statistically significant difference was found in NRS-2002 scores at admission and discharge in both genders, and the scores increased (P &lt; 0.05). While a significant relationship was found between immunonutrition support and gender (P &lt; 0.05), no relationship was found between genders in terms of the diet given and the consumption status of the diet intake (P &gt; 0.05). No statistically significant difference was found between genders in terms of feeding duration with nutritional support products, energy intake with nutritional support products and diet, macronutrients, and total energy expenditure values (P &gt; 0.05). Since burn injuries can cause serious metabolic disorders, impaired nutritional status was encountered during hospitalization. While the treatment process was positively affected by the increase in the NRS-2002 score during hospitalization, a decrease in parameters such as albumin, total protein, and anthropometric measurement values brought about by the catabolic process was encountered. Therefore, to prevent or treat malnutrition, the nutritional status of patients should be evaluated at the time of hospitalization and they should be able to receive the necessary nutritional support.

Nutritional risk, nutrition impact symptoms, and dietary intake after four or more days of admission: A cross-sectional study on hospitalised patients

BackgroundRegular audits on nutrition screening, therapy, and dietary intake monitoring are essential for ensuring optimal nutrition practice. This study aimed to investigate the prevalence of nutritional risk, nutritional coverage, and nutrition impact symptoms (NIS) in hospitalized patients. MethodsA cross-sectional study was conducted, including adult patients admitted for ≥5 days on November 1, 2023. Data were collected from medical records to estimate the prevalence of nutritional risk using the NRS-2002 score. Additionally, data on dietary intake and NIS were collected through interviews with patients identified as being at nutritional risk. ResultsA total of 104 patients (48% females) were included in the study, with 51% identified as being at nutritional risk. Patients at nutritional risk and those not at risk differed significantly in terms of length of admission (median 9 (IQR: 7-17) vs. 7 days (6-11), p=0.015) and BMI (median 22.3 (IQR: 20.3-27.7) vs. 25.9 (22.9-29.7), p=0.015). Patients at nutritional risk had a median energy coverage of 60% (IQR: 38-87) and a median protein coverage of 45% (IQR: 36-82). However, only 42% of them achieved an energy intake of ≥75% of the estimated requirement, while 28% met the same level for protein intake. The most prevalent NIS affecting dietary intake was 'diarrhea, constipation, or discomfort from the stomach', reported by 50% of patients. ConclusionThis study highlights the significant prevalence of nutritional risk among hospitalised patients, with one in every two patients identified as being at risk. Despite efforts, nutritional needs were not adequately met, particularly regarding protein intake. Regular audits and interdisciplinary collaboration are necessary for improving nutritional care and outcomes in hospital settings.

The early prognostic value of the 1–4-day BCM/PA trend after admission in neurocritical patients

The purpose of this study was to investigate early stage dynamic changes in relevant indicators in neurocritical patients to identify biomarkers that can predict a poor prognosis at an early stage (1–4 days after admission). This study retrospectively collected clinical data, inflammatory indicators, and nutritional indicators from 77 patients at the neurology intensive care unit. The 3-month modified Rankin scale score was used as the outcome indicator. A linear mixed model was used to analyze changes in inflammatory indicators and nutritional indicators in neurocritical patients over time from 1–4 days after admission. Logistic regression was used to determine the independent risk factors for a poor prognosis in neurocritical patients and to construct a predictive model. The predictive efficacy of the model was verified using leave-one-out cross-validation and decision curve analysis methods. The analysis results showed that 1–4 days after admission, the inflammatory indicators of white blood cell and absolute monocyte counts and the nutritional indicators of body cell mass(BCM), fat-free mass, body cell mass/phase angle (BCM/PA), intracellular water, extracellular water, and skeletal muscle index increased overall, while the nutritional indicators of albumin and visceral fat area decreased overall. The logistic multivariate regression model showed that the Charlson comorbidity index (CCI) (odds ratio (OR) = 2.526, 95% CI [1.202, 5.308]), hemoglobin (Hb)(on admission)-Hb(min) (OR = 1.049, 95% CI [1.015, 1.083), BCM(on admission) (OR = 0.794, 95% CI [0.662, 0.952]), and the change in BCM/PA 1–4 days after admission (OR = 1.157, 95% CI [1.070, 1.252]) were independent risk factors for a poor prognosis in neurocritical patients. The predictive analysis showed that the predictive power of Model 1 with BCM/PA (area under the curve (AUC) = 0.95, 95% CI (0.90, 0.99)) was 93%, 65%, 141%, and 133% higher than that of Model 2 without BCM/PA, the CCI, the APACHE II score, and the NRS2002 score (all P < 0.05), respectively. The CCI, Hb(on admission)-Hb(min), BCM(on admission), and an increase in BCM/PA 1–4 days after admission were independently associated with a poor prognosis in neurocritical patients. Of these variables, BCM/PA may be a valid indicator for early stage prediction of a poor prognosis in neurocritical patients.

Analysis of Grip Strength and Its Explanatory Factors in Older Patients with Gastrointestinal Tumours.

To investigate the grip strength of older patients with gastrointestinal tumours and analyse its explanatory factors. A total of 170 older patients with gastrointestinal tumours admitted to the Gastrointestinal Surgery Department of a Grade-III hospital in the Zhejiang province from January 2022 to December 2022 were selected as the investigation participants. Among them, there were 102 cases of gastric cancer (60.0%) and 68 cases of colon cancer (40.0%). There were 110 male patients (64.7%) and 60 female patients (35.3%), with patient ages ranging between 64 and 82 years old. A cross-sectional survey was conducted using a general data questionnaire, grip apparatus and the Nutritional Risk Screening 2002 (NRS-2002) score. Multiple linear regression was used to analyse the explanatory factors on the grip strength of older patients with gastrointestinal tumours. The grip strength of older patients with gastrointestinal tumours was 25.3±5.3 kg. Multiple linear regression analysis showed that gender, age, disease, body mass index (BMI), albumin concentration and the NRS-2002 score were the main explanatory factors on grip strength (P<0.05). Grip strength was lower in older patients with gastrointestinal tumours and was lower in females, those aged ≥70 years, patients with colorectal cancer, individuals with a BMI of <18.5, those with an albumin concentration of <35g/l and those with an NRS2002 score of ≥3. Clinical staff should dynamically evaluate the level of grip strength in patients with gastrointestinal tumors and develop individualized interventions based on the related explanatory factors.

Complementarity of nutrition screening with Global Leadership Initiative on Malnutrition criteria for diagnosing malnutrition in critically ill patients: A comparison study of Nutritional Risk Screening 2002 and modified Nutrition Risk in the Critically Ill Score.

Critical illness induces hypermetabolism and hypercatabolism, increasing nutrition risk (NR). Early NR identification is crucial for improving outcomes. We assessed four nutrition screening tools (NSTs) complementarity with the Global Leadership Initiative on Malnutrition (GLIM) criteria in critically ill patients. We conducted a comparative study using data from a cohort involving five intensive care units (ICUs), screening patients for NR using NRS-2002 and modified-NUTRIC tools, with three cutoffs (≥3, ≥4, ≥5), and malnutrition diagnosed by GLIM criteria. Our outcomes of interest included ICU and in-hospital mortality, ICU and hospital length of stay (LOS), and ICU readmission. We examined accuracy metrics and complementarity between NSTs and GLIM criteria about clinical outcomes through logistic regression and Cox regression. We established a four-category independent variable: NR(-)/GLIM(-) as the reference, NR(-)/GLIM(+), NR(+)/GLIM(-), and NR(+)/GLIM(+). Of the 377 patients analyzed (median age 64 years [interquartile range: 54-71] and 53.8% male), NR prevalence varied from 87% to 40.6%, whereas 64% presented malnutrition (GLIM criteria). NRS-2002 (score ≥4) showed superior accuracy for GLIM-based malnutrition. Multivariate analysis revealed mNUTRIC(+)/GLIM(+) increased >2 times in the likelihood of ICU and in-hospital mortality, ICU and hospital LOS, and ICU readmission compared with the reference group. No NST exhibited satisfactory complementarity to the GLIM criteria in our study, emphasizing the necessity for comprehensive nutrition assessment for all patients, irrespective of NR status. We recommend using mNUTRIC if the ICU team opts for nutrition screening, as it demonstrated superior prognostic value compared with NRS-2002, and applying GLIM criteria in all patients.

Assessment of the Nutritional Status and Skeletal Muscle Condition in Patients With Resectable Gastric Cancer

Background: Patients with gastric cancer (GC) are at high risk of nutrient deficiencies (ND) that can negatively affect the postoperative period and long-term treatment outcomes.Objective: To assess the nutritional status (NS) and skeletal muscle condition in patients with resectable stage I-III GC.Materials and methods: Our study included 102 GC patients: 64 men (62.7%) and 38 women (37.3%) aged 31 to 77 years. During the assessment we used the NRS-2002 system, determined laboratory markers of the NS, calculated the Nutritional Risk Index (NRI), and evaluated the condition of adipose tissue and skeletal muscles using computed tomography.Results: We found that 70.6% of the patients had ND: NRS-2002 score &lt; 3 points (52%) and NRS-2002 score ≥ 3 points (18.6%). Risk factors for ND were tumor localization in the cardia and stage III GC. Laboratory markers of ND were transferrin and NRI. Among the examined patients (n = 80) sarcopenia was detected in 10 (12.5%) patients: 1 patient (1/25; 4.0%) from the group without ND, 6 patients (6/42; 14.3%) from the group with NRS-2002 score &lt; 3 points, and 3 patients (3/13; 23.1%) from the group with NRS2002 score ≥ 3 points, (P = .212). In multivariate logistic regression analysis, independent factors associated with sarcopenia were age, body mass index, and total protein.Conclusions: All GC patients selected for radical surgery should undergo nutritional assessment using special tools (NRS-2002, NRI) and evaluation of the skeletal muscle condition. Sarcopenia may occur in patients with no clinical or laboratory evidence of ND. In GC patients at nutritional risk, preand postoperative nutritional support should be considered to reduce the ND-related risks.

A cross-sectional survey study on the correlation analysis of nutritional status and intestinal flora in patients with esophageal cancer.

This study aims to examine the nutritional status of individuals diagnosed with esophageal cancer and compare the nutritional indicators and intestinal flora between malnourished and non-malnourished patients. The findings aim to contribute to the early prevention of malnutrition and the development of interventions targeting the intestinal flora to treat esophageal cancer. An 80-patient sample of hospitalized individuals with esophageal cancer was selected from the radiotherapy department of our hospital between July 2021 and July 2022 to evaluate NRS2002 scores and PG-SGA scores. This cross-sectional analysis aimed to examine the disparities in dietary nutrient intake, blood indicators, body composition, and fecal intestinal flora between malnourished and non-malnourished patients with esophageal cancer. Additionally, we randomly selected 40 cases to predict and analyze the relationship between intestinal flora and malnutrition. The incidence of nutritional risk and malnutrition in patients with esophageal cancer was 62.5% and 60%, respectively. The low intake of carbohydrates and dietary fiber in the malnutrition group was statistically significant compared to those in the non-malnutrition group (P < 0.05). The albumin (ALB) level was lower in the malnutrition group than in the non-malnutrition group, while the C-reactive protein (CRP) level was higher; these differences were also statistically significant (P < 0.05). The basal metabolic rate, phase angle, body cell mass, muscle mass, skeletal muscle index, and fat-free mass index in the malnutrition group all decreased compared to the non-malnutrition group. The extracellular water/total body water was higher than that in the non-malnutrition group, which was also statistically significant (P < 0.05). As shown by 16S rDNA sequencing of fecal intestinal flora, there was no significant difference in α and β diversity between the malnutrition and non-malnutrition groups; at the genus level, significant differences were observed for Selimonas, Clostridioides, Dielma, Lactobacillus, and [Eubacterium]_siraeum_group. However, Dielma, Sellimonas, and Clostridioides were significantly lower in the malnutrition group than in the non-malnutrition group, while Anaerococcus, Atopobium, Eubacterium_siraeum_group, and Lactobacillus were significantly higher in the malnutrition group. Correlation analysis between different genera and clinical indicators showed that Lactobacillus was positively correlated with ALB, dietary energy, intracellular water/total body water (ICW/TBW), phase angle (PA), muscle mass (MM), skeletal muscle mass (SMM), body cell mass (BCM), basal metabolic rate (BMR), appendicular skeletal muscle mass (ASMM), total body water (TBW), fat-free mass index (FFMI), skeletal muscle index (SMI), fat-free mass (FFM), Weight, body mass index (BMI) (r > 0, P < 0.05), but negatively correlated with PG-SGA score, NRS2002 score, and extracellular water/total body water (ECW/TBW) (r < 0, P < 0.05). Based on PG-SGA, there was only a low accuracy for identifying nutrient deficiency (most areas under curve (AUC) values fell within 0.5 to 0.7, or even lower), with Lachnoclostridium's AUC being 0.688 (CI = 0.518-0.858) and Lactobacillus_salivarius_g_Lactobacillus's AUC being 0.257 (CI = 0.098-0.416). A KEGG functional analysis based on 16S data indicated potential differences affecting glucose metabolism pathways and the synthesis or division of DNA, influencing the onset, development, and prognosis of esophageal cancer patients. Esophageal cancer patients are more likely to be malnourished. The nutritional status of these patients is closely linked to the intake of carbohydrates and fiber, albumin levels, inflammation levels, and lean body mass. Furthermore, the patient's intestinal flora composition plays a significant role in their nutritional well-being. Consequently, modulating the intestinal flora holds promise as a potential therapeutic approach for addressing malnutrition in esophageal cancer patients. ChiCTR2100048141.

Correlation between plasma lycopene levels in patients with laryngeal carcinoma and postoperative adverse complications of chemoradiotherapy and nutritional risks.

In this study, we analyzed the correlation between the preoperative plasma lycopene levels, postoperative adverse complications of chemoradiotherapy, and nutritional risk scores in patients with laryngeal carcinoma. A total of 114 patients with laryngeal carcinoma and 114 healthy respondents were enrolled in this study. The patients with laryngeal carcinoma were divided into two groups: 62 patients with laryngeal carcinoma, with an NRS2002 score higher than 3 points and whose diet contained lycopene, were enrolled in the observation group, and 52 patients with laryngeal carcinoma during the corresponding time period, whose diet did not contain lycopene, were enrolled in the reference group. The immune indexes (CD4 + , CD8 + , IGA, IGM, IGG), nutritional indexes (albumin, prealbumin, transferrin), and postoperative adverse complications of chemo-radiotherapy in the two groups were recorded. The lycopene levels were lower in patients with advanced tumor stage (III and IV). The diagnosis threshold of the plasma lycopene level for laryngeal carcinoma was 0.503μmol/L. The area under the curve for plasma lycopene levels in cancer diagnosis was 0.96, with a clinical specificity of 0.943 and a sensitivity of 0.859. There was a significant negative correlation between the plasma lycopene levels and Nutrition Risk Screening (NRS) 2002 score (R2 = - 0.523, P < 0.001), which was related to the increase in NRS-2002 scores and nutritional hazards in patients with laryngeal carcinoma. The observation group showed a significant increase in nutritional and immune indices, as compared to the reference group, as well as a lower incidence of severe and serious adverse reactions to chemo-radiotherapy. Lycopene supplementation, tumor stage, NRS-2002 scores, nutritional and immune indices were all significant predictors of postoperative severe and serious adverse complications of chemoradiotherapy. Progression of laryngeal carcinoma and severity of the side effects of the adverse complications of chemo-radiotherapy are related to the levels of lycopene.

Malnutrition risk in hospitalized patients measured with Nutrition Risk Screening 2002 tool and its association with in-hospital mortality.

Malnutrition is related to increased morbidity, mortality, and costs. NRS-2002 is a practical malnutrition risk (MR) screening tool approved by the European Society for Clinical Nutrition and Metabolism (ESPEN) for inpatients. We aimed to reveal the inpatient MR using NRS-2002, and to examine the relationship between MR and in-hospital mortality. The results of inpatient nutritional screening in a tertiary referral center university hospital were retrospectively analyzed. The NRS-2002 test was used for defining MR. Comorbidities, initial and follow-up anthropometric data, NRS-2002 score, food intake, weight status, and laboratory analysis were examined. In-hospital mortality was noted. Data from 5,999 patients were evaluated. On admission, 49.8% of the patients had MR, and 17.3% had severe MR (sMR). MR-sMR was higher in geriatric patients (62.0-28.5%). Those with dementia had the highest MR (71%), followed by stroke (66%) and malignancy (62%). Age and serum C-reactive protein (CRP) were higher, and body weight, BMI, serum albumin, and creatinine were lower in patients with MR. Multivariate analysis showed that age, albumin, CRP, congestive heart failure (CHF), malignancy, dementia, and stroke were independently associated with MR. The overall mortality rate during hospitalization was 7.9%. MR was associated with mortality regardless of serum CRP, albumin, body mass index (BMI), and age. Half of the patients received nutritional treatment (NT). NT resulted in preserved or increased body weight and albumin levels among patients and the geriatric group with MR. AMR revealed that NRS-2002 is positive in approximately half of the hospitalized patients, which is associated with in-hospital mortality independent of the underlying diseases. NT is related to weight gain and increased serum albumin.

Nutritional risk and a high NRS2002 score are closely related to disease progression and poor prognosis in patients with COVID-19.

Organism can lead to excessive nutrient consumption in the infected state and increase nutritional risk, which is detrimental to the control of the infection and can further aggravate the disease. To investigate the impact of nutritional risk and the NRS2002 score on disease progression and prognosis in patients with COVID-19. This was a retrospective cohort study including 1,228 COVID-19 patients, who were divided into a with-nutritional risk group (patients with NRS2002 score ≥ 3) and a without-nutritional risk group (patients with NRS2002 score < 3) according to the NRS2002 score at admission. The differences in clinical and outcome data between the two groups were compared, and the relationship between the NRS2002 score and the disease progression and prognosis of COVID-19 patients was assessed. Of 1,228 COVID-19 patients, including 44 critical illness patients and 1,184 non-critical illness patients, the rate of harboring nutritional risk was 7.90%. Compared with those in the without-nutritional risk group, patients in the with-nutritional risk group had a significantly longer coronavirus negative conversion time, significantly lower serum albumin (ALB), total serum protein (TP) and hemoglobin (HGB) at admission, discharge or 2 weeks, a significantly greater proportion with 3 or more comorbidities, and a significantly higher rate of critical illness and mortality (all p < 0.001). Multiple regression analysis showed that nutritional risk, NRS2002 score and ALB at admission were risk factors for disease severity. In addition, nutritional risk, NRS2002 score and TP at admission were risk factors for prognosis. The NRS2002 score showed the best utility for predicting critical illness and death in COVID-19 patients. Nutritional risk and a high NRS2002 score are closely related to disease progression and poor prognosis in COVID-19 patients. For patients with NRS2002 score > 0.5, early intervention of malnutrition is needed to reduce the occurrence of critical disease. Additionally, for patients with NRS2002 score > 5.5, continuous nutritional support therapy is needs to reduce mortality and improve prognosis.Clinical Trial registration: [https://www.chictr.org.cn/historyversionpub.aspx?regno=ChiCTR2000034563], identifier [Chinese Clinical Trial Register ChiCTR2000034563].

Frailty combined with nutritional risk score in predicting postoperative complications of elderly patients with gastrointestinal malignancies

ObjectiveExploring the predictive power of frailty combined with nutritional risk on postoperative complications in elderly gastrointestinal malignancies patients. MethodsElderly patients who underwent gastrointestinal cancer surgery at Gastrointestinal Surgery Department of the Affiliated Hospital of Binzhou Medical University from August 2021 to June 2022 were selected as the research subjects. The patients' frailty and nutritional status were assessed using the Fried Frailty Scale and the NRS2002 Nutritional Risk Scale within 24 h of admission. Observing and recording the diagnosis and treatment of postoperative complications during the hospitalization. Results202 patients were enrolled, including 119 patients (58.91%) with nutritional risk and 89 patients (44.06%) with frailty. Frailty was an independent risk factor for postoperative complications [OR = 5.904, 95%CI (3.103, 11.233)]. The AUC value of frailty assessment was 0.780, which was greater than the AUC value of NRS2002 score of 0.705 (P < 0.01). The AUC value of frailty assessment combined with NRS-2002 score was 0.844, which was significantly higher than that alone (P < 0.01). ConclusionsThe ability of frailty to predict postoperative complications is better than the NRS-2002 score. Frailty combined with nutritional risk assessment can increase the predictive power of postoperative complications in elderly gastrointestinal malignancies patients.

Survival and factors affecting the survival of older adult patients in palliative care.

Investigate the survival and risk factors that affect the survival of aged patients in a palliative care center (PCC). A total of 180 inpatients (aged ≥ 65years) who were admitted to a PCC from January 2018 to March 2020 were included. Information regarding patients' demographic characteristics, chronic diseases, length of hospital stay, nutrition provided at the first hospital stay, pressure wound, pain, and laboratory results were evaluated. The patients 50% were women (n = 90). The mean age, mean comorbidity, and mean follow-up duration was 77.6years, 3.4, and 115days (median: 29days), respectively. The mean NRS2002 score of patients was 4.0 ± 1.0 and the risk of malnutrition was 93%. The mortality rate of the patients was 91.7%. The life expectancy of patients without malignancy was higher than those with malignancy (p < 0.001). Enteral nutrition (EN) via percutaneous endoscopic gastrostomy (PEG) was associated with up to two-fold increase in the survival rates of patients with PCC (p = 0.049, HR: 2.029). High neutrophil/lymphocyte ratio (p = 0.002, HR: 1.017) and high ferritin (p = 0.001, HR: 1.000) and C-reactive protein (CRP) levels (p < 0.001, HR: 1.006) were adverse risk factors affecting life expectancy. Malignity reduced the survival rate of aged patients with PCC by 40% (p = 0.008). EN via PEG was found to be a positive factor affecting survival rates of older adult patients in palliative care, whereas malignity, high neutrophil/lymphocyte ratio, high CRP and ferritin levels, and prolonged hospital stays were negative risk factors.

Low inter-rater reliability between nurses and researchers for the NRS-2002 screening tool for malnutrition in a hematological hospital ward

NRS-2002 is one of the recommended tools to screen hospitalized patients for malnutrition. NRS-2002 is considered as valid and reliable, but little is known about the inter-rater reliability between different groups of healthcare professionals. The aim of this study was to test the inter-rater reliability of the NRS-2002 tool between department nurses and researchers. Inter-rater reliability was measured between the NRS-2002 scores given by department nurses and researchers, using data from a randomized controlled trial (RCT) at a hematological department in a Norwegian hospital. The mean NRS-2002 score was significantly higher when using researchers' scores compared to the department nurses' scores. The total agreement between the two groups of raters was 59%, kappa=0.27. The inter-rater reliability of the NRS-2002 scores given by nurses and researchers was low. More research is needed to study if this is applicable also to other patient groups and in other wards.

Nutritional risk screening 2002 scale and subsequent risk of stroke-associated infection in ischemic stroke: The REMISE study.

Background and aimStroke-associated infection (SAI) is a common and serious complication in patients with IS. This study aimed to evaluate the impact of nutritional status at admission assessed on SAI, explore the predictive value of the Nutritional Risk Screening 2002 (NRS-2002 for SAI.MethodsThis study included patients with IS who were admitted to five major hospitals in Chengdu from January 2017 to February 2019. The nutritional status was assessed using the NRS-2002 tool. Logistic regression analysis was performed to explore the predictive value of NRS-2002 for SAI.ResultsA total of 594 patients with IS were included in this study; among them, 215 (36.20%) patients were at risk of malnutrition, and 216 (36.36%) patients developed SAI. The area under the curve of the NRS-2002 scores was smaller than A2DS2 (0.644 vs. 0.779), and NRS-2002 improved the predictive values of the A2DS2 score(Age, Atrial fibrillation, Dysphagia, Sex, Stroke Severity) for SAI (P < 0.001). Logistic regression analysis showed that patients with NRS-2002 score ≥ 3 had significantly higher risks of SAI (NRS-2002: odds ratios (OR) = 1.450, 95% confidence interval (CI): 1.184–1.692, P < 0.001).ConclusionNRS-2002 is a useful and simple tool for identifying the risk of SAI. Malnutrition is related to the development of SAI. Malnourished patients with stroke may benefit from further nutritional supplements and management.

Associations of intermuscular adipose tissue and total muscle wasting score in PG-SGA with low muscle radiodensity and mass in nonmetastatic colorectal cancer: A two-center cohort study.

BackgroundsThe patient-generated subjective global assessment (PG-SGA) is one of the screening criteria for malnutrition, the skeletal muscle radiodensity (SMD) and skeletal muscle mass index (SMI) are associated with survival in colorectal cancer patients. Body composition parameters can be easily assessed; however, few studies have examined the association between total muscle wasting scores in PG-SGA and body composition parameters and two muscle abnormalities.MethodsThis cohort study included 1,637 stage I-III CRC patients from 2 clinical centers in China, who were enrolled in the training cohort (n = 1,005) and validation cohort (n = 632). Baseline data were collected prospectively from patients including age, BMI, staging, gait speed, hand grip strength (HGS), peak expiratory flow (PEF), neutrophil-lymphocyte ratio (NLR), intermuscular adipose tissue (IMAT), visceral fat area (VFA) and total muscle wasting score in PG-SGA. Relevant risk factors were subjected to logistic regression analysis and Cox regression analysis to identify characteristics associated with muscle abnormalities and survival. Based on the logistic model results, normograms were established to predict muscle abnormalities, and its discrimination and calibration were assessed using the receiver operating characteristic (ROC) curve and calibration curve. The Kaplan-Meier curves were used to assess the survival of colorectal cancer patients with malnutrition or sarcopenia in an inflammatory state (assessed by NLR).ResultsThe mean age of all participants was 57.7 ± 10.6 years (56.9% males) and the prevalence of low SMD and low SMI was 32.2 and 39.5%, respectively. Low SMD rate was significantly associated with age, TNM stage, BMI, IMAT, walking speed, total muscle wasting score and NRS2002 score by logistic regression analysis (p < 0.05). Low SMI rate was significantly correlated with age, NLR, BMI, PEF, handgrip strength, calf circumference, walking speed, total muscle wasting score and NRS2002 score (p < 0.05). The AUCs of the diagnostic nomograms were 0.859 (95% CI, 0.831–0.886) for low SMD and 0.843 (95% CI, 0.813–0.871) for low SMI in the validation cohort. We also found that patients with colorectal cancer with malnutrition or sarcopenia had a worse prognosis when NLR ≥3.5.ConclusionMuscle abnormalities and malnutrition are strongly associated with mortality in patients with non-metastatic colorectal cancer. Early identification and intervention of the associated risk factors may offer new ways to improve patient prognosis.

Association of Different Malnutrition Parameters and Clinical Outcomes among COVID-19 Patients: An Observational Study.

Background: Malnutrition is highly prevalent in medical inpatients and may also negatively influence clinical outcomes of patients hospitalized with COVID-19. We analyzed the prognostic implication of different malnutrition parameters with respect to adverse clinical outcomes in patients hospitalized with COVID-19. Methods: In this observational study, consecutively hospitalized adult patients with confirmed COVID-19 at the Cantonal Hospital Aarau (Switzerland) were included between February and December 2020. The association between Nutritional Risk Screening 2002 (NRS 2002) on admission, body mass index, and admission albumin levels with in-hospital mortality and secondary endpoints was studied by using multivariable regression analyses. Results: Our analysis included 305 patients (median age of 66 years, 66.6% male) with a median NRS 2002-score of 2.0 (IQR 1.0, 3.0) points. Overall, 44 patients (14.4%) died during hospitalization. A step-wise increase in mortality risk with a higher nutritional risk was observed. When compared to patients with no risk for malnutrition (NRS 2002 < 3 points), patients with a moderate (NRS 2002 3–4 points) or high risk for malnutrition (NRS 2002 ≥ 5 points) had a two-fold and five-fold increase in risk, respectively (10.5% vs. 22.7% vs. 50.0%, p < 0.001). The increased risk for mortality was also confirmed in a regression analysis adjusted for gender, age, and comorbidities (odds ratio for high risk for malnutrition 4.68, 95% CI 1.18 to 18.64, p = 0.029 compared to patients with no risk for malnutrition). Conclusions: In patients with COVID-19, the risk for malnutrition was a risk factor for in-hospital mortality. Future studies should investigate the role of nutritional treatment in this patient population.
