Cut-off values of Geriatric Nutritional Risk Index for cardiovascular events in Japanese patients with acute myocardial infarction.

The Geriatric Nutritional Risk Index (GNRI) is a straightforward nutritional risk assessment tool with an established relationship with poor prognosis in patients with heart failure. However, the utility of the GNRI in patients with acute myocardial infarction (AMI) remains unclear given the time-dependent changes in the pathophysiology of AMI and the selected endpoints. Accordingly, we aimed to evaluate the optimal cut-off values of the GNRI for cardiovascular events in patients with AMI. We used time-dependent receiver operating characteristic analysis to identify the optimal cut-off values for two endpoints, all-cause death and major adverse cardiac events (MACE: all-cause death, non-fatal myocardial infarction, hospitalization for heart failure, and stroke), over 4years in 360 patients with AMI between 2012 and 2020. The cumulative incidence of MACE was 11.6%. The cut-off value of the GNRI for all-cause death was 82.7 (area under the curve [AUC], 0.834) at 3months and 90.3 (AUC 0.854) at 4years. The cut-off value of the GNRI for MACE was 83.0 (AUC 0.841) at 3months and 95.3 (AUC 0.821) at 4years. The GNRI demonstrated consistently high reliability relative to other indicators of AMI. Our findings indicated that the optimal cut-off value and reliability of the GNRI for cardiovascular events varied according to the endpoints and observation periods. GNRI emerges as a crucial predictor of prognosis for patients with AMI.

FP2.2 - Does preoperative nutritional assessment correlate with postoperative outcomes of patients undergoing surgery due to colorectal cancer? A bicenter prospective observational study

Abstract Aims Preoperative nutritional status has been investigated as a risk factor for postoperative complications in patients undergoing surgery due to colorectal surgery. The aim of the present study was to investigate the predictive role of preoperative nutritional assessment in terms of morbidity and mortality in such patients. Methods Patients undergoing surgery due to colorectal cancer from March 2022 until March 2023 at two university surgical departments were included in the present study. Patients’ demographics and postoperative parameters, such as complications’ severity according to Clavien-Dindo classification and mortality, along with malignancy stage were reported. Preoperative nutritional assessment was conducted according to the Patient-Generated Subjective Global Assessment (PG-SGA) tool and the Geriatric Nutritional Risk Index (GNRI) tool. The present study was registered in ClinicalTrials.gov (NCT05795374). Results The present study included 159 patients with a mean age of 69 ± 12 years old. Severe malnutrition according to the PG-SGA tool was associated with advanced disease stage (66% vs 59%, p=0.006). In addition, the high risk of malnutrition according to the GNRI tool was correlated to major (Clavien-Dindo≥3) postoperative complications (19% vs 15%, p=0.026) and increased 30-day mortality (34% vs 9%, p=0.026). Conclusions Postoperative morbidity and mortality of patients undergoing surgery due to colorectal cancer seem to be associated with preoperative nutritional stratification, especially with the high malnutrition risk.

The relationship between Geriatric Nutritional Risk Index (GNRI) and in-hospital mortality in critically ill patients with Acute Kidney Injury (AKI)

BackgroundThe role of the geriatric nutritional risk index (GNRI) as a prognostic factor in intensive care unit (ICU) patients with acute kidney injury (AKI) remains uncertain.ObjectivesThe aim of this study was to investigate the impact of the GNRI on mortality outcomes in critically ill patients with AKI.MethodsFor this retrospective study, we included 12,058 patients who were diagnosed with AKI based on ICD-9 codes from the eICU Collaborative Research Database. Based on the values of GNRI, nutrition-related risks were categorized into four groups: major risk (GNRI < 82), moderate risk (82 ≤ GNRI < 92), low risk (92 ≤ GNRI < 98), and no risk (GNRI ≥ 98). Multivariate analysis was used to evaluate the relationship between GNRI and outcomes.ResultsPatients with higher nutrition-related risk tended to be older, female, had lower blood pressure, lower body mass index, and more comorbidities. Multivariate analysis showed GNRI scores were associated with in-hospital mortality. (Major risk vs. No risk: OR, 95% CI: 1.90, 1.54–2.33, P < 0.001, P for trend < 0.001). Moreover, increased nutrition-related risk was negatively associated with the length of hospital stay (Coefficient: -0.033; P < 0.001) and the length of ICU stay (Coefficient: -0.108; P < 0.001). The association between GNRI scores and the risks of in-hospital mortality was consistent in all subgroups.ConclusionsGNRI serves as a significant nutrition assessment tool that is pivotal to predicting the prognosis of critically ill patients with AKI.

Evaluating the Impact of Nutritional Risk on Stress-Induced Hyperglycemia and Trauma Patient Outcomes.

Stress-induced hyperglycemia (SIH) and malnutrition are common in trauma patients and are linked to worse outcomes. This study examined the influence of nutritional status, determined by the Geriatric Nutritional Risk Index (GNRI), on the incidence of SIH in trauma patients. A retrospective analysis was conducted on adult trauma patients admitted to a Level I trauma center from 1 January 2009 to December 31, 2021. Patients were categorized into four groups: SIH, diabetic hyperglycemia (DH), diabetic normoglycemia (DN), and non-diabetic normoglycemia (NDN). Nutritional status was assessed using GNRI: high risk (GNRI < 82), moderate risk (82 ≤ GNRI < 92), low risk (92 ≤ GNRI ≤ 98), and no risk (GNRI > 98). Incidence of SIH and outcomes were analyzed across GNRI groups. SIH was associated with higher mortality across all GNRI groups compared to NDN, with the highest rate (45.7%) in the high-risk group. Mortality decreased as GNRI increased in all glucose groups. NDN patients had the lowest mortality rates across GNRI groups. There was no correlation between GNRI and SIH incidence (p = 0.259). SIH significantly influenced mortality across all nutritional status groups, with the highest impact in malnourished patients. Although malnutrition did not affect SIH incidence, both SIH and poor nutritional status independently contributed to worse trauma outcomes. Targeted management of hyperglycemia and nutritional deficiencies is crucial for improving survival.

Association between geriatric nutritional risk index and cognitive function in older adults with/without chronic kidney disease.

Cognitive impairment is highly prevalent among patients with chronic kidney disease, who face an increased risk of cognitive decline. The aim of this study was to investigate the relationship between the Geriatric Nutritional Risk Index (GNRI) and cognitive function in older individuals, both with and without chronic kidney disease (CKD). In this study, we analyzed data from 2728 participants in the 2011-2014 National Health and Nutrition Examination Survey (NHANES). Cognitive function was measured using the Consortium to Establish a Registry for the Alzheimer's Disease Word Learning subtest (CERAD W-L), the animal fluency test (AFT), the digit symbol substitution test (DSST), and the global cognitive z-score. The GNRI, representing whole-body nutritional status, was calculated based on serum albumin, body weight, and ideal body weight. We employed weighted multiple linear regression analyses and subgroup analyses to assess the independent association of GNRI with cognitive function in CKD and non-CKD populations. Smoothing techniques were used to fit curves, and interaction tests were used to assess the robustness and specificity of the findings. Our analyses revealed a significant positive association between higher GNRI levels and cognitive function in the older US population (for global z-score: β=0.01; 95% confidence interval [CI]=0.00, 0.01). This association remained consistent across various subgroup analyses, including those for different gender groups, age groups, smoking statuses, diabetes statuses, hypertension statuses, individuals with a BMI below 25, individuals who consumed alcohol, and non-Hispanic white individuals. Smoothed curve-fitting analyses indicated that the GNRI was linearly related to cognitive function. No statistically significant interactions were detected among these variables. Our findings emphasize the positive association between GNRI and cognitive health in individuals with or without CKD, especially when combined with other risk factors. Consequently, enhancing the nutritional status of the elderly may serve as a viable strategy to thwart the onset of cognitive decline.

Association of geriatric nutritional risk index with bone mineral density and osteoporosis in postmenopausal elderly women with T2DM.

To investigate the relationship between geriatric nutritional risk index (GNRI) and osteoporosis (OP) in postmenopausal elderly women with type 2 diabetes mellitus (T2DM). A total of 141 postmenopausal elderly women with T2DM was divided into OP and normal bone mineral density (BMD) groups, the differences in GRNI levels between the two groups were compared. According to the tertile levels of GRNI, T2DM were divided into three groups (T1, T2, T3 groups), and the differences in OP prevalence and levels of BMD among the three groups were compared. Among postmenopausal elderly women with T2DM, GNRI levels were lower in the OP group compared to the nor-mal BMD group [(103±5.46) vs. (105±5.46), p<0.05)]. With elevated GNRI levels, the BMD levels of femoral, total hip, total body, and lumbar vertebrae (L) were gradually increased, which were higher in the T3 group than in the T1 group (all p< 0.05). GNRI levels were positively correlated with the BMD levels of femoral, spine, total hip, total body, L1, L2, L3, L4, and L1-L4. GNRI was an independent influencing factor for the occurrence of OP (OR=0.887, 95%CI [0.795,0.988]). The ROC curve showed that the GNRI combined with serum ALP and P levels had a high predictive value for OP, with an area under the curve of 0.725 (p<0.01). In postmenopausal elderly women with T2DM, GNRI was independently and positively correlated with BMD levels. GNRI may be a predictor development of OP.

The Geriatric Nutritional Risk Index as a prognostic factor in patients treated with immune checkpoint inhibitors with non-small-cell lung cancer.

Globally, non-small cell lung cancer (NSCLC) is a leading factor in cancer-related mortality. Additionally, the Geriatric Nutritional Risk Index (GNRI) has been assessed as a predictive and prognostic indicator in various types of carcinomas. Our study aims to assess the prognostic importance of GNRI computed at diagnosis in NSCLC patients receiving immune checkpoint inhibitors (ICIs). The study evaluated 148 patients who underwent immunotherapy for NSCLC from January 1, 2018, through December 31, 2021, retrospectively. Patients combined with other malignant tumors or severe comorbidities were excluded from the study. The receiver operating characteristic (ROC) curve was employed in regulating the ideal cutoff worth of GNRI. Survival outcomes were evaluated through Kaplan-Meier analysis. Following this, both univariate and multivariate analyses were conducted utilizing Cox regression analysis to identify any potential factors that may influence the survival outcomes. The cutoff point for GNRI was 108.15 [area under the curve (AUC) =0.575, P=0.048]. Further analysis using the Kaplan-Meier method demonstrated that individuals in the high GNRI group had significantly longer progression-free survival (PFS) and overall survival (OS) compared to those in the low GNRI group (P=0.02, P=0.01). The further stratified study showed that GNRI had greater predictive value in tumor node metastasis (TNM) stage II-III and elderly (age ≥65 years) NSCLC patients undergoing ICI therapy. The multivariate Cox regression analysis indicated that GNRI [hazard ratio (HR): 0.536, P=0.03], obesity (HR: 16.283, P<0.001), and surgical history (HR: 0.305, P<0.001) were associated with poorer survival rates. Among patients undergoing ICI therapy for NSCLC, GNRI is an effective independent prognostic indicator, and a high GNRI at diagnosis is substantially related with longer PFS and OS. The incorporation of GNRI in pre-treatment evaluations within clinical settings is beneficial.

Preoperative Nutrition Impacts Retear Rate After Arthroscopic Rotator Cuff Repair.

A rotator cuff retear following arthroscopic rotator cuff repair (ARCR) is a concern in older patients. However, only a few of its risk factors are amenable to preoperative intervention. We aimed to elucidate the relationship between preoperative nutritional status and rotator cuff retears after ARCR. This single-center retrospective study included patients aged ≥65 years with rotator cuff tears who underwent ARCR. The Geriatric Nutritional Risk Index (GNRI) was used to assess preoperative nutritional status. Data collection encompassed patient demographics, clinical assessments, and surgical specifics. Patients were divided into healed and retear groups based on 2-year post-ARCR magnetic resonance imaging results. Logistic regression analysis was conducted to adjust for confounding factors and detect independent risk factors for retears. The GNRI cutoff value for retear prediction was determined by a stratum-specific likelihood ratio; clinical outcomes were compared based on the cutoff values obtained. Overall, 143 patients were included. The retear rate was 20.3%. The albumin level, GNRI, postoperative shoulder strength of abduction and external rotation, and postoperative Japanese Orthopaedic Association and Constant scores in the retear group were significantly lower than those in the healed group. The logistic regression analysis showed that low risk of morbidity and mortality (compared with no risk) based on the GNRI (odds ratio [OR], 3.39) and medial-lateral tear size per mm (OR = 1.10) were independent risk factors for a retear 2 years after ARCR. Stratum-specific likelihood ratio analysis identified data-driven strata as GNRI < 103, 103 ≤ GNRI < 109, and GNRI ≥ 109. Univariate analysis showed that patients with GNRI < 103 had a significantly higher retear risk than those with 103 ≤ GNRI < 109 and those with GNRI ≥ 109. Logistic regression analysis showed that GNRI < 103 compared with 103 ≤ GNRI < 109 (OR = 3.88) and GNRI < 103 compared with GNRI ≥ 109 (OR = 5.62), along with the medial-lateral tear size per mm (OR = 1.10), were independent risk factors for a retear at 2 years after ARCR. When assessing the risk of a retear after ARCR, GNRI ≥ 103 may indicate good preoperative nutritional status. However, more data are essential to ascertain the importance of this finding.

Investigation of situation for development of infection, nutritional and length of hospital stay in elderly hospitalized in a palliative clinic

Aim: In our study, we aimed to evaluate patients' nutritional status, compare frequently used nutritional scales with each other and with the duration of hospitalization, and measure the effect of nutritional status on infection and mortality who are in the elderly. Materials and Methods: Nutritional Risk Screening-2002, Mini Nutritional Assessment, and Geriatric Nutritional Risk Index were used. Patients were monitored for infection and mortality throughout the hospitalization period. Results: The prevalence of malnutrition was found 98.6% with Mini Nutritional Assessment, 97.3% with Nutritional Risk Screening-2002, and 87.1% with Geriatric Nutritional Risk Index. A high correlation was found between the Geriatric Nutritional Risk Index and albumin, body mass index, arm, and calf circumference. Conclusion: The malnutrition rate is quite high in patients who need palliative care. The Geriatric Nutritional Risk Index, compared to Nutritional Risk Screening-2002 and Mini Nutritional Assessment, is an effective and user-friendly scale that contains objective variables in bed-dependent patients for nutrition.

A novel nomogram based on inflammatory-nutritional biomarkers for gallbladder cancer after surgical resection

PurposeSystemic inflammation and nutrition are vital for tumor progression. This study aimed to identify prognostic inflammation nutrition markers and develop a predictive nomogram for gallbladder cancer (GBC).MethodsA total of 123 patients with GBC who underwent surgical resection at the First Affiliated Hospital of Soochow University and Suzhou Kowloon Hospital were included in our study. The final prognostic variables were identified using univariate and multivariate analyses. A nomogram model was then established, and the consistency index (C-index), calibration curves, and Kaplan–Meier analysis were performed to evaluate the accuracy and discrimination of the nomogram. The area under the receiver operating characteristic curve (AUC) and decision curve analysis (DCA) suggested that our nomogram had better predictive ability and clinical feasibility than a published model.ResultsThe cox regression analysis showed that carcinoembryonic antigen (CEA) > 4.580, albumin-bilirubin (ALBI) > –2.091, geriatric nutritional risk index (GNRI) < 90.83, T3–T4, and N2 are independent prognostic factors. A predictive nomogram was constructed with a C-index of 0.793. In the calibration curves, the nomogram-predicted 1-, 3-, and 5-year survival matched well with the actual survival. Kaplan–Meier analysis showed that the high-risk group had worse survival than the low-risk group (P < 0.001). Finally, our nomogram achieved better 1-, 3- and 5-year AUCs than an established model (0.871, 0.844, and 0.781 vs. 0.753, 0.750, and 0.693). DCA also confirmed that our model outperformed the established model.ConclusionsIn conclusion, our study revealed that CEA > 4.580, GNRI < 90.83, ALBI > –2.091, T3–T4 stage, and N2 were related to clinical outcomes of patients with GBC after surgical resection. The constructed nomogram has superior predictive ability and clinical practicality.

Performance of nutritional and inflammatory markers in patients with pancreatic cancer.

Systemic inflammation and nutrition play pivotal roles in cancer progression and can increase the risk of delayed recovery after surgical procedures. To assess the significance of inflammatory and nutritional indicators for the prognosis and postoperative recovery of patients with pancreatic cancer (PC). Patients who were diagnosed with PC and underwent surgical resection at our hospital between January 1, 2019, and July 31, 2023, were enrolled in this retrospective observational cohort study. All the data were collected from the electronic medical record system. Seven biomarkers - the albumin-to-globulin ratio, prognostic nutritional index (PNI), systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), nutritional risk index (NRI), and geriatric NRI were assessed. A total of 446 patients with PC met the inclusion criteria and were subsequently enrolled. Patients with early postoperative discharge tended to have higher PNI values and lower SII, NLR, and PLR values (all P < 0.05). Through multivariable logistic regression analysis, the SII value emerged as an independent risk factor influencing early recovery after surgery. Additionally, both univariable and multivariable Cox regression analyses revealed that the PNI value was the strongest prognostic marker for overall survival (OS; P = 0.028) and recurrence-free survival (RFS; P < 0.001). The optimal cutoff PNI value was established at 47.30 using X-tile software. Patients in the PNI-high group had longer OS (P < 0.001) and RFS (P = 0.0028) times than those in the PNI-low group. Preoperative systemic inflammatory-nutritional biomarkers may be capable of predicting short-term recovery after surgery as well as long-term patient outcomes.

The geriatric nutritional risk index is related to adverse hospitalization outcomes in individuals undergoing cardiac surgery

Malnutrition is linked to adverse outcomes in post-cardiac surgery patients. This study investigates the correlation between the Geriatric Nutritional Risk Index (GNRI) and adverse hospital outcomes in patients following cardiac surgery. This retrospective study included elderly patients with heart disease who were admitted to the Department of Cardiology, Fujian Medical University Union Hospital from January 2020 to December 2022. Patients were divided into two groups based on the cut-off value (98 g/dL). Data from 407 patients were assessed, with 278 (68.3%) classified as having nutritional risk and 129 (31.7%) as having no nutritional risk. Notable distinctions were observed in body weight, BMI, and left ventricular ejection fraction (P < 0.05). Laboratory indicators indicated lower levels of serum albumin, lymphocytes, red blood cells, hemoglobin, admission blood glucose, and admission triglyceride in the nutritional risk group (P < 0.05). Neutrophils and serum creatinine were higher in the nutritional risk group (P < 0.05). Poor prognosis was prevalent in the nutrition risk group (64.7%), with higher incidences of adverse outcomes (P < 0.05). Univariate and multivariate studies showed that GNRI < 98 g/dL was an independent predictor of postoperative cardiac surgery. Nutritional risk was an important predictor of adverse hospital outcomes after the surgery.

Association between the geriatric nutritional risk index and cognitive functions in older adults: a cross-sectional study from National Health and Nutrition Examination Survey.

To investigate the associations between the geriatric nutritional risk index (GNRI) with cognitive functions among U.S. older adults. (Patients were classified into two nutrition risk groups based on the GNRI). Our analysis utilized data from the cross-sectional National Health and Nutrition Examination Survey (NHANES) conducted between 2011 and 2014. Cognitive function was measured using CERAD test, AFT and DSST. Composite z-scores were obtained by summing test-specific z-scores of the above three cognitive tests and were used to assess the global cognitive function. We employed weighted logistic regression models to evaluate the associations between GNRI and nutritional status (low and high GNRI) with cognitive function among older participants. The non-linear relationship was described using fitted smoothed curves and threshold effect analyses. Subgroup analysis and interaction tests were also conducted. This study included 2,592 older participants aged 60 years and older. After adjusting for confounding variables, the GNRI was positively associated with AFT (β = 0.05, 95% CI 0.005-0.096, p-value = 0.0285), DSST (β = 0.192, 95% CI 0.078-0.305, p-value = 0.0010) and the composite z-scores (β = 0.027, 95% CI 0.010-0.044, p-value = 0.0024). The results also showed that the high-GNRI group was significantly associated with AFT (β = 0.922, 95% CI 0.166-1.677, p-value = 0.0169), DSST (β = 2.791, 95% CI 0.884-4.698, p-value = 0.0042) and composite z-scores (β = 0.405, 95% CI 0.115-0.695, p-value = 0.0062) likewise had significant positive correlations, using the low-GNRI group as a reference. In addition, inflection points with CERAD and composite z-scores were found at GNRI of 108.016, and 105.371, respectively. Specifically, on the left side of the inflection point GNRI levels were positively correlated with CERAD and composite z-scores (CERAD β = 0.087, 95% CI 0.024-0.150, p-value = 0.0070; composite z-scores β = 0.065, 95% CI 0.040-0.091, p-value <0.0001), while on the right side of the inflection point were significantly negatively associated (CERAD β = -0.295, 95% CI -0.529 to -0.062, p-value = 0.0133, composite z-scores β = -0.050, 95% CI -0.091 to -0.008, p-value = 0.0184). Lower GNRI was associated with poorer performance in several cognitive domains. Additionally, there was a non-linear positive association between GNRI and cognitive function in normal nutritional states, for excessive GNRI may cause cognitive decline.

Preoperative Malnutrition Calculated Using the Geriatric Nutritional Risk Index in Off-Pump Coronary Artery Bypass Grafting

Background: The Geriatric Nutritional Risk Index (GNRI), which assesses nutritional status using the ideal body weight ratio and albumin level, is a useful predictor of long-term cardiovascular disease prognosis. This study aimed to investigate the impact of preoperative GNRI on off-pump coronary artery bypass (OPCAB) surgical outcomes. Methods: We analyzed 632 elective OPCAB procedures performed between July 2008 and July 2018. GNRI was calculated as 14.89 × albumin level (g/dL) + 41.7 × (current body weight [kg]/ideal body weight [kg]). Patients were divided into two groups: the low GNRI (≤98, L group, n = 155) and high GNRI (&gt;98, H group, n = 477) groups. We compared perioperative variables and mid-term outcomes, particularly survival rates and freedom from major adverse cardiac or cerebrovascular events (MACCE). Results: Patients in the L group were older (72.4 ± 8.6 vs. 67.9 ± 10.1 years, p &lt; 0.001) and had lower GNRI scores (90.9 ± 5.8 vs. 106.0 ± 4.8, p &lt; 0.001) than patients in the H group. Perioperative results, including operation time and number of anastomoses, were similar between the groups, with no significant differences in 30-day mortality, perioperative intra-aortic balloon pump use, bleeding, stroke, or mediastinitis rates were observed. However, patients in the L group had a longer postoperative hospital stay than those in the H group (15.4 ± 13.5 vs. 12.6 ± 5.8 days, p = 0.01). Analyses of long-term outcomes revealed a significant difference in 5-year survival rates (70.9% for the L group vs. 83.3% for the H group, p = 0.002) but no significant difference in 5-year MACCE rates (84.1% for the L group vs. 80.3% for the H group, p = 0.19). Conclusions: Despite the longer hospital stay for patients in the L group, other perioperative outcomes were similar between the groups, suggesting that a low GNRI should not preclude patients from undergoing OPCAB surgery.

Applicability of Global Leadership Initiative on Malnutrition (GLIM) criteria in nutrition risk screening for patients over 60 years old with digestive system tumors – A retrospective study

ObjectiveThis study aimed to identify the most effective nutritional risk screening tool for elderly patients with digestive system tumors. MethodsNutritional risk screening was performed using Nutritional Risk Screening 2002 (NRS2002), prognostic nutritional index (PNI) and Geriatric Nutritional Risk Index (GNRI) for elderly patients who underwent surgical resection of digestive tumor. Comparative analysis of each nutritional screening tool was conducted through Kappa test and ROC curve. ResultsMalnourished individuals diagnosed by the Global Leadership Initiative on Malnutrition (GLIM) criteria had lower levels of hematological parameters (serum albumin, pre-albumin, total protein and hemoglobin) and poorer body composition parameters (body mass index, body fat percentage, edema index, upper arm muscle circumference, skeletal muscle index, and phase angle; P<0.05). NRS2002 demonstrated a sensitivity of 75.56% and specificity of 38.16% under the GLIM criteria, showing moderate agreement (Kappa=0.346, P<0.001). PNI had an average sensitivity of 71.11% and the highest specificity at 87.23%, but exhibited no consistency with GLIM (Kappa=0.152, P=0.062). GNRI showed the highest sensitivity at 91.11% and general specificity at 37.14%, aligning closely with GLIM criteria (Kappa=0.711, P<0.001). GNRI had the highest predictive value (AUC=0.870, 95% CI: 0.801–0.939), followed by NRS2002 (AUC=0.687, 95% CI: 0.589–0.785). Patients diagnosed with malnutrition via GNRI-GLIM exhibited higher rates of surgical site infection (χ2=15.534, P<0.001) and 3-month readmission (χ2=4.499, P=0.034). ConclusionGNRI and NRS2002 demonstrate good performance as GLIM criteria for nutritional screening in elderly patients with digestive tumors, with GNRI being potentially more suitable. Moreover, GNRI-GLIM can predict short-term prognosis in these patients.

Prognostic factors for non‑metastatic castration‑resistant prostate cancer treated with androgen receptor signaling inhibitors.

The treatment paradigm for non-metastatic castration-resistant prostate cancer (nmCRPC) has changed in recent years. An observational multicenter study was conducted to evaluate the effectiveness of androgen receptor signaling inhibitors (ARSIs) as a first-line treatment for patients with nmCRPC. The present study included native Japanese patients from four hospitals who received ARSIs as a first-line treatment for nmCRPC. The primary endpoint of the study was to evaluate the efficacy and safety of ARSI in patients with nmCRPC. The secondary endpoint was to develop a novel system to stratify the prognoses of these patients. In total, 160 patients were included in the present study. Within a median follow-up period of 23 months, the median overall survival (OS) was not reached, whereas the median progression-free survival was 26 months. Multivariate Cox regression analyses showed that the time to CRPC, prostate-specific antigen (PSA) level at the initiation of nmCRPC treatment and Geriatric Nutritional Risk Index (GNRI) were independent predictors of OS. The patients for whom information about all three independent OS predictors was available were subsequently divided into three groups as follows: Group 1, 57 patients with negative or one positive independent OS predictor; group 2, 38 patients with two positive independent OS predictors; and group 3, 10 patients with three independent OS predictors. The OS differed significantly among the three groups (P<0.0001). In conclusion, ARSIs as a first-line treatment may be associated with favorable outcomes in Japanese patients with nmCRPC. Time to CRPC, PSA level at the initiation of nmCRPC treatment and GNRI are potential predictors of OS in Japanese patients with nmCRPC who received ARSIs as a first-line treatment.

Usefulness of serum transthyretin for prediction of the 1-year outcome in idiopathic pulmonary fibrosis: An evaluation of sarcopenic and nutritional indicators

BackgroundPatients with idiopathic pulmonary fibrosis (IPF) often experience sarcopenia and malnutrition. However, this has not been fully examined through longitudinal surveys. This study investigated whether sarcopenia and malnutrition were associated with 1-year outcomes in IPF. MethodsWe evaluated sarcopenia and nutritional status in 64 outpatients with IPF. We assessed the time-to-event for respiratory-related hospitalizations or deaths 12 months after enrollment. Sarcopenia was diagnosed by the criteria of the Asian Working Group for Sarcopenia, 2019. Nutritional status was assessed by serum transthyretin and the Geriatric Nutritional Risk Index (GNRI). ResultsThe average age was 73.6 ± 7.9 years, and the percent predicted forced vital capacity (FVC) was 81.9 ± 15.7%. Of the 64 patients, 24 (37.5%) had sarcopenia. The median serum transthyretin level and mean GNRI were 23.8 mg/dL and 102, respectively. Eleven patients (17.2%) experienced respiratory-related hospitalization or death within the first year. Cox regression analysis showed that the % predicted diffusion capacity for carbon monoxide, lowest oxygen saturation in the 6-min walk test, serum transthyretin level, and GNRI were significant predictors of 1-year outcomes. The Kaplan–Meier method, which divided the patients into two groups based on a transthyretin level of 22.6 mg/dL, showed a significant difference (P < 0.001, log-rank test). Sarcopenia and the percent predicted FVC did not predict the 1-year outcomes. ConclusionsThis pilot study represents the first longitudinal survey assessing patients with IPF for sarcopenia and malnutrition. Serum transthyretin levels may predict respiratory-related hospitalization or death within 1 year in patients with IPF.

Negative Association of GNRI with All-Cause Mortality in Chinese Atrial Fibrillation Patients: A Multicenter Retrospective Cohort Study

Introduction: Malnutrition is common in older atrial fibrillation (AF) patients and results in poor clinical outcomes. The Geriatric Nutritional Risk Index (GNRI) is a straightforward method for evaluating nutritional health. However, its prognostic value in AF patients is unclear. This research focused on examining the correlation between GNRI and overall mortality in Chinese individuals with AF. Methods: We performed a multicenter retrospective study at four Chinese hospitals involving patients diagnosed with AF between January 2019 and August 2023. Using GNRI, nutritional status was evaluated, classifying patients into three categories. Multivariable logistic regression and restricted cubic spline analysis assess the relationship between GNRI and mortality, with exploratory subgroup analyses investigating potential effect modifiers. Results: The study included 4,878 AF patients with a median follow-up of 19 months. The mean age was 71 (63–78), and the mean GNRI was 102 (95–108). Malnutrition was identified in 1,776 patients (36.41%). During the study, 419 (8.59%) deaths occurred. After controlling for confounders, moderate to severe malnutrition was linked to an increased risk of all-cause mortality compared to no malnutrition (odds ratio 1.50; 95% CI, 1.17–1.94). The relationship between GNRI and mortality risk was approximately linear, with consistent associations across subgroups. Conclusion: Malnutrition, as assessed by GNRI, is prevalent among Chinese AF patients and is independently linked to higher all-cause mortality risk.
