A Comparative Study of Three Nutritional Risk/Screening Indices for Predicting Cardiac Events and Physical Functioning Among Patients with Acute Heart Failure

Clinical impacts of malnutrition based on the GLIM criteria using the MNA-SF for nutritional screening in patients with acute heart failure

The Global Leadership Initiative on Malnutrition (GLIM) suggested a two-step framework for the assessment of malnutrition based on screening and diagnosis. Malnutrition, as defined by the GLIM criteria, and the risk of malnutrition determined through nutritional screening are associated with adverse outcomes in patients with heart failure (HF). This study investigated the prognostic impact of malnutrition, as defined by the GLIM criteria, compared with the risk of malnutrition determined by the Mini Nutritional Assessment-Short Form (MNA-SF) screening tool among patients hospitalized for acute HF. A total of 446 patients with acute HF who underwent nutritional screening using the MNA-SF and were diagnosed with malnutrition based on the GLIM criteria were include in this study. The primary outcome was the incidence of all-cause death or HF-related readmission after discharge. Patients diagnosed with malnutrition based on both indices had a higher incidence of adverse events within one year post-discharge than patients diagnosed without malnutrition. However, a landmark analysis of years one to three post-discharge found that the incidence of the primary outcome was comparable between patients diagnosed with malnutrition and those that here not. Furthermore, although malnutrition as defined by the GLIM criteria was found to be an independent predictor of the 1 year incidence of all-cause death or rehospitalization for HF even after adjusting for other prognostic indicators (hazard ratio, 1.593; 95% confidence interval, 1.056-2.403; P = 0.026), the risk of malnutrition based on the MNA-SF was not. In conclusion, a diagnosis of malnutrition based on the GLIM criteria provides better prognostic stratification in the first year post-discharge in patients with acute HF as compared with nutritional screening based only on the MNA-SF.

Impact of nutritional status in patients with metastatic spinal tumors who underwent palliative surgery

BACKGROUND

Preoperative nutritional status significantly affects postoperative outcomes in patients with metastatic spinal tumors. Understanding the relationship between nutritional status and survival rates can help optimize treatment strategies and improve patient outcomes.

METHODS

This retrospective study was performed on 57 patients who underwent palliative surgery between May 2009 and April 2023. Various indicators of nutritional status including the Japanese-modified Glasgow Prognostic Score (JmGPS), C-reactive protein-to-albumin ratio (CAR), and prognostic nutrition index (PNI) were evaluated.

RESULTS

Results showed that a lower JmGPS and CAR and a higher PNI were associated with a longer survival after surgery. Patients with a JmGPS score of 0 had a better postoperative performance status, higher likelihood of postoperative chemotherapy, and a greater median survival (>1 year). Further, CAR and PNI were predictive indicators of a better postoperative performance status and the implementation of chemotherapy.

CONCLUSION

Assessing preoperative nutritional status can predict survival and postoperative outcomes in patients with metastatic spinal tumors. The current findings underscore the importance of nutritional assessment in optimizing treatment strategies and improving outcomes.

Controlling Nutritional Status Score Predicts 1-Year Outcomes in Chronic Thromboembolic Pulmonary Hypertension

Background

The prognosis for patients with chronic thromboembolic pulmonary hypertension (CTEPH) using their nutritional status has not been established. We investigated the relationship between the prognosis of patients with CTEPH and the Controlling Nutritional Status (CONUT) score, which is a nutritional assessment tool.

Methods and Results

A total of 157 patients with CTEPH was enrolled in the study. The primary outcome was defined as the composite outcome of all-cause mortality and non-elective hospitalization due to heart failure. Receiver operating characteristic (ROC) curve analysis was used to determine the cutoff CONUT score for predicting the 1-year rate of the primary outcome. Patients were divided into 2 groups according to the significant cutoff value and compared. Undernutrition was observed in 51.6% of patients. ROC analysis revealed a significant cutoff CONUT score of 3.5 (area under the curve=0.789). The incidence rate of the primary composite outcome was higher in the high CONUT group (score ≥4) than in the low CONUT group (score ≤3; 20% vs. 2.2%; P<0.001). Cox analysis revealed the CONUT score per point increase was an independent risk factor for the primary composite outcomes (hazard ratio 2.301; 95% confidence interval 1.081-4.895; P=0.031).

Conclusions

The CONUT score can predict the 1-year rate of all-cause death and non-elective hospitalization in patients with CTEPH.

Association between Controlling Nutritional Status (CONUT) Score and Body Composition, Inflammation and Frailty in Hospitalized Elderly Patients

The Controlling Nutritional Status (CONUT) score has demonstrated its ability to identify patients with poor nutritional status and predict various clinical outcomes. Our objective was to assess the association between the CONUT score, inflammatory status, and body composition, as well as its ability to identify patients at risk of frailty in hospitalized elderly patients.

METHODS

a total of 361 patients were retrospectively recruited and divided into three groups based on the CONUT score.

RESULTS

patients with a score ≥5 exhibited significantly higher levels of inflammatory markers, such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Neutrophil/Lymphocytes ratio (NLR), main platelet volume (MPV), and ferritin, compared to those with a lower score. Furthermore, these patients showed unfavorable changes in body composition, including a lower percentage of skeletal muscle mass (MM) and fat-free mass (FFM) and a higher percentage of fatty mass (FM). A positive correlation was found between the CONUT score and inflammatory markers, Geriatric Depression Scale Short Form (GDS-SF), and FM. Conversely, the Mini Nutritional Assessment (MNA), Mini-Mental Status Examination, activity daily living (ADL), instrumental activity daily living (IADL), Barthel index, FFM, and MM showed a negative correlation. Frailty was highly prevalent among patients with a higher CONUT score. The receiver operating characteristic (ROC) curve demonstrated high accuracy in identifying frail patients (sensitivity).

CONCLUSIONS

a high CONUT score is associated with a pro-inflammatory status as well as with unfavorable body composition. Additionally, it is a good tool to identify frailty among hospitalized elderly patients.

Preprocedural Controlling Nutritional Status Score as a Predictor of Mortality in Patients Undergoing Transcatheter Mitral Valve Repair - A Single Center Experience in Japan

Background: A high score for controlling nutritional status (CONUT) due to poor nutritional status has been associated with adverse outcomes in patients with chronic heart failure. However, because little is known about the effect of CONUT score on mortality rates after transcatheter mitral valve repair, we evaluated nutrition screening tools for prognosis prediction in patients undergoing transcatheter mitral valve repair using the MitraClipTM system. Methods and Results: We retrospectively analyzed 148 patients with severe mitral regurgitation (MR) who underwent MitraClipTM implantation between April 2018 and April 2021. The preprocedural CONUT scores were assessed at the time of hospitalization, the primary outcome was all-cause death, and the analysis was of the mortality and incidence rates of cardiac events 1 year post-operation. Functional MR was of ischemic origin in the majority of patients (69.6%), with a mean left ventricular ejection fraction of 48.9±15.8%. Kaplan-Meier curves indicated that all-cause death was significantly worse in the high-CONUT score group than in the low-CONUT score group. Cox hazard analysis showed a significant association between all-cause death and CONUT score, as well as MitraScore. Conclusions: Preprocedural CONUT score, as well as MitraScore, in patients undergoing transcatheter edge-to-edge mitral valve repair may predict an increased risk of all-cause death. This knowledge should allow the heart team to accurately assess the clinical implications and prognostic benefits of the procedure in individual patients.

Prognostic value of nutritional screening tools in hospitalized patients with decompensated heart failure: A systematic review and meta-analysis

Nutritional risk screening is fundamental to prevent undesirable outcomes in heart failure (HF). Current reviews of nutritional screening tools encompass both hospitalized and outpatient settings, which may not be suitable because of different clinical manifestations. We hypothesize that multidimensional tools would better identify prognosis of decompensated patients because the tools assess more than isolated aspects. This systematic review aims to explore the association of multidimensional nutritional risk screening tools and prognosis in patients hospitalized with decompensated HF. Five databases were searched for studies that assessed nutritional risk through multidimensional screening tools and its association with prognosis in adults hospitalized with decompensated HF. The 95% confidence interval and relative risk were computed using a random-effects model. Inverse variance method was used. Thirty-eight studies were included. Most studies demonstrated higher nutritional risk was significantly associated with worse prognosis. Quantitative analysis identified higher nutritional risk by using the Mini Nutritional Assessment Short Form (MNA-SF), Controlling Nutritional Status, Geriatric Nutritional Risk Index, and Prognostic Nutritional Index to be associated with all-cause mortality. The MNA-SF demonstrated greater magnitude of association with all-cause mortality in older subjects (relative risk, 4.85; 95% confidence interval, 2.0-11.75). Higher nutritional risk was associated with poor prognosis and higher mortality in patients hospitalized with decompensated HF, especially when screened by MNA-SF. Tools were not directly compared. That might reinforce the importance of evaluating multiple aspects when screening hospitalized HF patients once symptoms associated with decompensation frequently mask the underlying nutritional status and risk.

Appetite Predicts Long-Term Clinical Outcomes in Patients with Acute Myocardial Infarction

BACKGROUND

Recently, the nutritional status of patients has drawn attention in an aging society. Early studies have reported that nutritional status is related to long-term outcomes in patients with acute myocardial infarction (AMI). However, it is not necessarily simple to evaluate the nutritional status of patients with AMI. We hypothesized that appetite before discharge can be a predictor for long-term adverse cardiovascular events in patients with AMI. This retrospective study aimed to investigate whether appetite is related to long-term adverse outcomes in patients with AMI.

METHODS

This study included 1006 patients with AMI, and divided them into the good appetite group (n = 860) and the poor appetite group (n = 146) according to the percentage of the dietary intake on the day before discharge. Major adverse cardiac events (MACE), which were defined as a composite of all-cause death, non-fatal MI, and re-admission for heart failure, were set as the primary outcome.

RESULTS

The median follow-up duration was 996 days, and a total of 243 MACE was observed during the study period. MACE was more frequently observed in the poor appetite group than in the good appetite group (42.5% versus 21.0%, p < 0.001). In the multivariate COX hazard model, poor appetite was significantly associated with MACE (Hazard ratio 1.698, 95% confidence interval 1.243-2.319, p < 0.001) after controlling for multiple confounding factors.

CONCLUSION

Appetite at the time of discharge was significantly associated with long-term clinical outcomes in patients with AMI. Patients with poor appetite should be carefully followed up after discharge from AMI.

Controlling nutritional status score predicts 2-year outcomes in elderly patients admitted for acute heart failure

BACKGROUND

Heart failure (HF) is a major cause of death among the elderly. Its prevalence increases dramatically with age. The prevalence of malnourished subjects is high in hospitalized elderly patients. We aimed to investigate the prognostic role of malnutrition, assessed by controlling nutritional status (CONUT) score, on adverse clinical outcomes in the elderly admitted for acute HF.

METHODS

We enrolled 293 patients (mean age 84 years; 48% men) consecutively admitted for acute HF to the Internal Medicine or Geriatrics Divisions at the 'IRCCS Sacro Cuore-Don Calabria' Hospital of Negrar (Verona, Italy) from 2013 to 2015. We predicted the risk of all-cause death, re-hospitalizations for HF and non-HF causes, and the composite of all-cause death or hospitalizations over 2-year follow-up. Patients were divided into four groups according to CONUT score: normal-CONUT (0-1; n = 30); mild-CONUT (2-3; n = 56); moderate-CONUT (4-7; n = 171); and severe-CONUT (≥ 8; n = 36).

RESULTS

Higher CONUT scores were associated with older age and lower entry blood pressures. No difference in hemodynamics was noted at the discharge. Kaplan-Meier curves showed a significant association between worsening CONUT scores and risk of all-cause death (p < 0.01), re-hospitalizations (p < 0.01), or both (p < 0.001). Cox regression analysis revealed these significant associations persisted after adjustment for age, sex, pre-existing cardiovascular disease, diabetes, chronic kidney disease, heart rate, systolic blood pressure, and plasma brain natriuretic peptide levels at discharge (all-cause mortality HR = 1.29 (1.00-1.66), p = 0.049; hospitalization for HF HR = 1.36 (1.03-1.81), p = 0.033; hospitalization for non-HF HR = 1.38 (1.03-1.86), p = 0.034; composite outcome HR = 1.33 (1.07-1.64), p = 0.01).

CONCLUSIONS

Malnutrition, assessed by the CONUT score, is common among elderly patients admitted for acute HF and is strongly related to increased long-term risk of all-cause death and re-hospitalizations.

Nutritional Status Is Associated With Survival Following Spinal Surgery in Patients With Metastatic Spinal Tumors

Background Preoperative and postoperative nutritional statuses are reported to influence the outcomes and complications of multidisciplinary treatment, including patient survival. However, a causal relationship between nutritional status and survival following spinal surgery has not been demonstrated in patients with metastatic spinal tumors. The present study was, therefore, designed to evaluate the correlation between the nutritional status and survival following spinal surgery in patients with metastatic spinal tumors. Methods Nutritional status was evaluated using the Japanese version of the modified Glasgow prognostic score (JmGPS), C-reactive protein-to-albumin ratio (CAR), prognostic nutrition index (PNI), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), which were calculated from the results of preoperative laboratory tests. The survival period was defined as the interval between the day preoperative data were obtained and the day of death. Results Data from 57 of 113 consecutive surgeries were retrieved. The CAR, JmGPS, and PNI were significantly correlated with the survival period (CAR, r = -0.576, P < 0.01; JmGPS, r = -0.537, P < 0.01; PNI, r = 0.316, P = 0.02). Furthermore, patients with 0 points on the JmGPS had significantly longer survival. Using receiver operating characteristic curves, CAR cutoffs of ≥0.880 and ≤0.220 were found to be optimal in predicting the 90- and 180-day postoperative survival, respectively. Conclusions The findings of the present study indicate that preoperative assessment of the JmGPS, CAR, and PNI has utility in estimating nutritional status and predicting survival following spinal surgery in patients with metastatic spinal tumors.

Differences in clinical outcomes between octogenarian and nonagenarian patients with acute heart failure

AIM

The number of hospitalized super-elderly patients with heart failure (HF) has increased with aging of the population. These patients are associated with poor clinical outcomes with the advance of age; however, few reports regarding acute HF have compared the clinical outcomes of nonagenarians with those of octogenarians.

METHODS

This study enrolled 683 patients aged ≥80 years who were admitted to our institution for acute HF between 2016 and 2020. The outcomes of interest were the 1-year all-cause mortality, incidence of cardiac events (cardiac-related death or HF-related readmission), and physical function during hospitalization of patients with survival-to-discharge. Physical function was evaluated using the Barthel index.

RESULTS

Post-discharge all-cause mortality, particularly non-cardiac mortality, was significantly higher in nonagenarians than octogenarians. Conversely, the incidence of cardiac death or rehospitalization for HF after discharge was comparable between the two groups. On admission, the Barthel index score was significantly lower in nonagenarians than octogenarians, and further decreased during hospitalization. Nonagenarians required social support at discharge more often than octogenarians (67.4% vs. 44.4%; P < 0.001).

CONCLUSIONS

The current study demonstrated that nonagenarians have poorer non-cardiac outcomes and were more vulnerable regarding physical activities than octogenarians among patients with acute HF. Holistic medical care, including palliative care and social support, will be increasingly required with increasing age. Geriatr Gerontol Int 2023; 23: 227-233.
