Association between prealbumin, all-cause mortality, and response to nutrition treatment in patients at nutrition risk: Secondary analysis of a randomized controlled trial. JPEN J Parenter Enteral Nutr 2023; 47:408-419. [PMID: 36587281 DOI: 10.1002/jpen.2470] [Citation(s) in RCA: 18] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 12/27/2022] [Accepted: 12/29/2022] [Indexed: 01/02/2023]
Abstract
BACKGROUND Because of the shorter half-life as compared with albumin, serum prealbumin concentrations have been proposed to be useful nutrition biomarkers for the assessment of patients at nutrition risk. In a post hoc analysis of patients at nutrition risk from a randomized controlled nutrition trial, we tested the hypothesis that (1) prealbumin is associated with higher all-cause 180-day mortality rates and that (2) individualized nutrition support compared with usual-care nutrition more effectively improves survival at 30 days in patients with low prealbumin levels compared with patients with normal prealbumin levels. METHODS We performed a prespecified cohort study in patients included in the pragmatic, Swiss, multicenter randomized controlled EFFORT trial comparing the effects of individualized nutrition support with usual care. We studied low prealbumin concentrations (<0.17 g/L) in a subgroup of 517 patients from one participating center. RESULTS A total of 306 (59.2%) patients (mean age 71.9 years, 53.6% men) had low admission prealbumin levels (<0.17 g/L). There was a significant association between low prealbumin levels and mortality at 180 days (115/306 [37.6%] vs 47/211 [22.3%], fully adjusted hazard ratio [HR]=1.59, 95% CI 1.11-2.28; P = 0.011). Prealbumin levels significantly improved the prognostic value of the Nutritional Risk Screening total score regarding mortality prediction at short- and long-term. The difference in mortality between patients receiving individualized nutrition support and usual-care nutrition was similar for patients with low prealbumin levels compared with patients with normal prealbumin levels (HR=0.90 [95% CI=0.51-1.59] vs HR=0.88 [95% CI=0.35-2.23]) with no evidence for interaction (P = 0.823). CONCLUSION Among medical inpatients at nutrition risk, low admission prealbumin levels correlated with different nutrition markers and higher mortality risk, but patients with low or high prealbumin levels had a similar benefit from nutrition support. Further studies should identify nutrition markers that help further personalize nutrition interventions.

Abstract
Objective Malnutrition is very commonly encountered in palliative care centers (PCC), especially in geriatric patients. It is known that development of malnutrition increases morbidity and mortality. In this study, we aimed to investigate the effectiveness of commonly used nutritional assessment parameters in predicting prognosis in geriatric patients diagnosed in PCC with malnutrition. Methods Our study included 1451 patients aged ≥65 years, who were diagnosed with malnutrition in PCC between 2016-2020 and did not yet start receiving nutritional support. Demographic data, comorbidities, The Nutritional Risk Screening 2002 (NRS-2002), body mass index (BMI), albumin, prealbumin and C-reactive protein (CRP) values of the patients were recorded. Prognostic course was evaluated by dividing the patients into 3 groups, namely mortal patients during PCC follow-up, patients transferred from PCC to Intensive Care (ICU) and patients discharged to home from PCC. Results Logistic Regression analysis showed that low albumin levels affected transfer to ICU (P<0.05). Elevated NRS-2002 and low albumin and prealbumin levels were found to be factors affecting mortality (P<0.05). Areas under the ROC Curve were calculated to attain patients' differential diagnosis. The area under the ROC Curve of low albumin in patients transferred to ICU was found to be significant (P<0.05). In the differential diagnosis of patients with mortal course, the area under the ROC Curve of low albumin and prealbumin and high CRP was found to be significant (P<0.05). Conclusion We found that BMI had no prognostic predictive effects in geriatric PCC patients with malnutrition. We concluded that NRS-2002 and high CRP and low albumin and prealbumin can be used to predict mortality. In addition, we found that low albumin indicates a poor prognosis and predicts patients to be transferred to ICU.

Abstract
Colorectal cancer (CRC) is the third most common malignant tumor and resection remains the key element in its treatment. The correction of preoperative malnutrition reduces morbidity and mortality. Our study demonstrates a nutritional state mass screening protocol to steer nutritional support. Two hundred fifty-nine patients with planned colorectal resection were prospectively enrolled. Preoperative telemedicinal assessment determined the risk of malnutrition using Nutritional Risk Screening 2002 (NRS 2002) score. Patients with a score ≥3 were offered optimized oral nutritional supplement. Three groups were investigated. Group I (NRS 2002 < 3, n = 98) received no supplement. Group II- (NRS 2002 ≥ 3, n = 118) was offered but did not finally receive clinical nutrition. Group II+ (NRS 2002 ≥ 3, n = 43) accepted and received adequate clinical nutrition. 98 patients (37.8%) had no risk, 154 patients (59.5%) had increased risk and 7 (2.7%) had severe malnutrition. Severe complications (Clavien-Dindo >2) rate was similar in Group I (2%) and Group II+ (2.3%) with no mortality. Severe complications more often occurred in Group II- (5.1%) along with 1.7% mortality (p > 0.05). Length of stay was the highest in Group II- while the lowest in Group II+ (p < 0.01). Preoperative telemedicinal screening is applicable in identifying patients with malnutrition. NRS 2002 used by a nutritional team reduces length of stay.

Abstract
Background and Objectives: This study aimed to assess the level of selected biochemical parameters in venous blood and their potential effects on the development of pressure ulcers in patients treated in intensive care settings. Materials and Methods: Fifty patients hospitalised in an intensive care unit (ICU) were enrolled for the study. The methods used included controlled observation, literature review and medical record analysis. The observation protocol applied in the study consisted of two parts comprising the basic information, sociodemographic data, results of laboratory tests (CRP, PCT, albumin, protein and haemoglobin concentrations) as well as the Braden Scale for Predicting Pressure Ulcer Risk. Results: The subjects presented moderate to high risk of pressure ulcers, reflected by the mean score of 8.18 ± 1.3 points, with minimum and maximum scores of 6 and 12 points, respectively. Normal albumin level was identified in only five subjects (10.0%) while 45 subjects (90.0%) were found with results below the norm. A statistical relationship was observed between such variables as albumin concentration (p < 0.01) and total protein level (p = 0.007). The findings show a strong correlation between the score in the Braden Scale and the level of albumins (R = 0.55). Conclusions: In our study, lower concentrations of albumins and total proteins correspond to a greater risk of pressure ulcers.

Abstract
BACKGROUND The Nutritional Risk Screening 2002 (NRS-2002) scale is a rapid and effective screening instrument that assesses nutritional risk among hospitalized patients. OBJECTIVE The present study aimed to explore the prognostic value of the NRS-2002 scale in acute myocardial infarction (AMI) considering its uncertain role in this particular condition. METHODS Patients with AMI included in the Retrospective Multicenter Study for Early Evaluation of Acute Chest Pain were investigated. Kaplan-Meier survival analysis and Cox proportional hazards models were used to analyze the association between NRS-2002 and mortality in patients with AMI. The primary and secondary endpoints were all-cause and cardiac mortality during the follow-up period. RESULTS A total of 2307 patients were enrolled, among whom 246 (10.7%) died within a median follow-up duration of 10.67 (8.04-14.33) months. Kaplan-Meier analysis revealed that patients with an NRS-2002 score of 3 or higher had poorer cumulative survival than those with an NRS-2002 score lower than 3 (P < .001). In the multivariate Cox regression analysis, patients with an NRS-2002 score of 3 or higher had more than double the risk for all-cause mortality (hazard ratio, 2.25; 95% confidence interval, 1.50-3.40; P < .001) and twice the risk for cardiac-related mortality (hazard ratio, 2.01; 95% confidence interval, 1.29-3.13; P = .002) than did patients with lower scores. CONCLUSIONS Our results showed that the NRS-2002 screening instrument was an independent prognostic predictor for both all-cause and cardiac mortality in patients with AMI. Nutritional risk assessment based on the NRS-2002 scale may provide useful prognostic information of early nutritional risk stratification in patients with AMI.

Abstract
BACKGROUND & AIMS Malnutrition is one of the most important factors affecting the prognosis of inpatients. The aim of this study is to determine the malnutrition risk of hospitalized patients and to examine the relationship between the presence of malnutrition and other parameters. METHODS The study included 162 inpatients over the age of 25 who were staying in the hospital's internal medicine service for 7 days or more and who volunteered to participate in the study. A demographic-information questionnaire, consisting of 5 sections, a 24-h food recall record, NRS-2002, NRI and Beck Depression Inventory was given to patients during bedside interviews. After obtaining the necessary permission, the anthropometric measurements and biochemical parameter values of the patients were taken from their files. All statistical analyzes were performed by researchers with the SPSS package program. RESULTS Of 162 patients (48.8% female, 51.2% male), 24.7% were at risk for malnutrition according to NRS-2002 and 66.7% of the patients were not depressive, based on the Beck Depression Inventory scale. The malnutrition risk was higher (60.0%) in patients who had been hospitalized for more than 15 days (p = 0.010). The majority of those with malnutrition had no problems preventing them from eating (32.5%), were found to be not depressive (52.5%) and were in the normal range of body mass index (57.5%) (p = 0.002, p = 0.034, p = 0.001; respectively). Nutrient intake was lower in patients with a higher malnutrition risk, but the difference was insignificant (p > 0.05). Albumin levels (p = 0.028) and total protein levels (p = 0.015) were significantly lower in patients who were at risk of malnutrition. While overweight patients showed higher levels of serum albumin (p < 0.001), CRP levels were found to be lower in overweight patients (p < 0.001). CONCLUSIONS It was found that the majority of patients with malnutrition were in the normal range for BMI. Nutritional intake and biochemical parameters should be followed closely in patients who are at risk of malnutrition. Depression can be a cause for insufficient nutrition and should be evaluated, particularly in patients whose length of hospital stay is greater than 7 days.

Abstract
A tool to assess nutritional status in older persons was really needed. It took 5 years to design the MNA® (Mini Nutrition Assessment) tool, complete the first validations studies both in Europe and in the U.S. and to publish it. After the full MNA®, the MNA® short form and the self-MNA® have been validated. As well as Chinese and other national MNA® forms. Now more than 2000 clinical research have used the MNA® all over the world from community care to hospital. At least 22 Expert groups included the MNA® in new clinical practice guidelines, national or international registries. The MNA® is presently included in almost all geriatric and nutrition textbook and part of the teaching program for medicine and other health care professional worldwide. The urgent need is to target the frail older adults more likely to have weight loss and poor appetite and to prevent frailty and weight loss in the robust. We present in this paper the review of 25 years of clinical research and practice using the MNA® worldwide.

Abstract
Introduction Introduction: oropharyngeal dysphagia (OD) has complications such as malnutrition and dehydration. Body composition is an important factor for nutritional status. Objective: to evaluate the presence of cachexia, phase angle, muscle strength, and nutritional risk according to the type of feeding regimen tolerated by patients, determined with the volume-viscosity swallow test (V-VST). Methods: this cross-sectional study included hospitalized adults of both sexes with a diagnosis of OD established by the Eating Assessment Tool and V-VST. Nutritional risk status was assesed using the Nutritional Risk Screening-2002 tool. Phase angle and cachexia were determined through bioelectrical impedance vector analysis (BIVA), and functional capacity through handgrip strength (HGS) and anthropometric parameters. Results: seventy-nine patients with a median age of 73 years (56-79 yrs) were included; 79.9 % of patients were categorized at nutritional risk. According to the V-VST, 27 (34.2 %) patients tolerated nectar viscosity; 27 (34.2 %) belonged to the spoon-thick and 25 (31.6 %) to the exclusive tube feeding groups. In the exclusive tube feeding group a lower phase angle (3.7° ± 0.9) and lower HGS of 9 kg (5-15) were observed in comparison to the nectar and spoon-thick groups (in both, 4.6° ± 1.1, p = 0.005), which featured 20 kg (16-31) and 19 kg (14-26), respectively (p = 0.03). Conclusion: nutritional risk was present in 79.9 % of the study population. BIVA allows to evaluate the integrity of muscle mass and tissue hydration, both related to phase angle. A lower phase angle and HGS were observed in the exclusive tube feeding group. These factors are considered important for prognosis.

Abstract
PURPOSE The rising proportion of elderly population in high-income societies has resulted in increasing number of subjects with chronic disabling diseases and nutritional deficiency. Elderly's nutritional status is usually assessed through the mini-nutritional assessment (MNA®). However, its effectiveness may be influenced by weight excess or obesity. We tested the performance of MNA® questionnaire in subjects aged ≥ 65 years from Northern Sardinia, Italy, according to overweight/obesity, and we tried to identify the factors associated with malnutrition. METHODS A modified version of MNA® (mMNA) test, not including BMI, was compared with the conventional MNA® (cMNA) test, and the overall test performance was assessed by calculating sensitivity, specificity and accuracy. In addition, indexes of cognitive health, disability, comorbidity and polypharmacy were compared between patients with concordant and discordant MNA tests. RESULTS cMNA® sensitivity, specificity and accuracy were 67%, 99% and 84% compared with the mMNA test, due to malnourished patients misclassified as normal because of excess weight. Predictors of malnutrition were: depression (p < 0.0001), disability (p < 0.0001) and polypharmacy (p < 0.0001). Interestingly, the average scores of the "global", "subjective" and "dietary" components of the cMNA®, were significantly lower compared with the corresponding scores of the mMNA. CONCLUSIONS Excess of weight, a condition progressively rising in the elderly population, may reduce the performance of cMNA® test in detecting malnutrition. LEVEL OF EVIDENCE Level III, case‒control analytic study.

Abstract
Background and Aim The presence of malnutrition in hospitalized geriatric patients is associated with an increased risk of mortality. This study aimed to examine the performance of Nutritional Risk Screening 2002 (NRS2002) and Mini Nutritional Assessment Short Form (MNA-SF) in predicting mortality for hospitalized geriatric patients in China. Methods A prospective analysis was performed in 536 hospitalized geriatric patients aged ≥65 years. Nutrition status was assessed using the MNA-SF and NRS2002 scales within 24 hrs of admission. Anthropometric measures and biochemical parameters were carried out for each patient. Patients were follow-up for up to 2.5 years. Results At baseline, 161 (30.04%) patients had malnutrition/nutritional risk according to NRS2002 assessment. According to MNA-SF, 284 (52.99%) patients had malnutrition/nutritional risk. Malnutrition/nutritional risk patients had lower anthropometric and biochemical parameters (P<0.05). NRS2002 and MNA-SF had a strong correlation with classical nutritional markers (P<0.05). NRS2002 versus MNA-SF showed moderate agreement (kappa=0.493, P<0.001). During a median follow-up time of 795 days (range 10-947 days), 118 (22%) participants died. The Kaplan-Meier curve demonstrated that malnutrition/nutritional risk patients according to NRS2002 or MNA-SF assessment had a higher risk of mortality than the normal nutrition patients (χ 2=17.67, P<0.001; χ 2=28.999, P<0.001, respectively). From the components of the Cox regression multivariate models, only the NRS2002 score was an independent risk factor influencing the mortality. Conclusion Both NRS2002 and MNA-SF scores could predict mortality in Chinese hospitalized geriatric patients. But only NRS2002 score was the independent predictor for mortality.

Abstract
INTRODUCTION The Nutritional Risk Screening 2002 (NRS 2002) identifies patients at risk of malnutrition. We studied the prognostic implications of this score with regard to short-term and long-term clinical outcomes in a well-characterised cohort of medical inpatients from a previous trial. METHODS This is a secondary analysis of an investigator-initiated, prospective randomised controlled multicenter trial in Switzerland (EFFORT) that compared the effects of an individualised nutritional support intervention with standard of care. We investigated associations between admission NRS and several short-term and long-term outcomes using multivariable regression analyses. RESULTS Of the 2028 patients, 31% had an NRS of 3, 38% of 4 and 31% of ≥5 points, and 477 (24%) died during the 180 days of follow-up. For each point increase in NRS, we found a stepwise increase in risk of 30-day mortality (adjusted Hazard Ratio (HR) 1.22 (95% CI 1.00 to 1.48), p = 0.048) and 180-day mortality (adjusted HR 1.37 (95% CI 1.22 to 1.55), p < 0.001). NRS was associated with length of hospital stay (adjusted difference of 0.60 days per NRS point increase, 95%CI 0.23 to 0.97, p = 0.002) and functional outcomes at 180 days (adjusted decrease in Barthel index of -4.49 points per NRS point increase, 95%CI -6.54 to -2.45, p < 0.001). In a subgroup analysis, associations of NRS and short-term adverse outcomes were less pronounced in patients receiving nutritional support (intervention group) compared to control group patients (adjusted HR for 30-day mortality 1.12 [95%CI 0.83 to 1.52, p = 0.454] vs. 1.33 [95%CI 1.02 to 1.72, p = 0.032]). CONCLUSION The NRS is a strong and independent risk score for malnutrition-associated mortality and adverse outcomes over 180 days. Our data provide strong evidence that the nutritional risk, however, is modifiable and can be reduced by the provision of adequate nutritional support.

Abstract
Background: This study aims to investigate the current status of feeding intolerance (FI) among patients with severe neurological conditions and to further determine the correlation between FI and their poor prognosis.Methods: This study performed a retrospective analysis of the medical data of 58 patients from January 2017 to December 2017. Patients were divided into two groups according to modified Rankin Scale (mRS) scores. Logistic regression was used to analyze the relevant factors for the poor prognosis of these patients.Results: General data analysis showed that age and diagnosis(stroke) were significantly different between the two groups (P < 0.05). Univariate analysis showed that APACHE II score, vomiting within 3 days of NICU admission, gastrointestinal bleeding within 3 days of NICU admission and occurrence of FI within 3 days of NICU admission were all risk factors for a poor prognosis of these patients(P < 0.05). Multivariate logistic regression analysis showed that FI within 3 days of NICU admission(OR 8.026, 95%CI(1.550-26.039)) and diagnosis(stroke)(OR 10.654, 95%CI (1.746-21.291)) were independent factors for a poor prognosis of patients with severe neurological conditions.Conclusion: The incidence of early FI in stroke patients is correlated with a poor prognosis.

Abstract
BACKGROUND AND PURPOSE In hospitals, poor nutritional status could be associated with a higher incidence of nosocomial infections, postoperative complications and mortality. Subsequently the costs of providing health care and social services will increase. Malnutrition has often been described as the skeleton in the hospital closet, as it is often ignored, undiagnosed and untreated. Our study aimed to describe the nutritional status of hospitalized patients aged 60 years or more and to evaluate the associated risk factors. MATERIALS AND METHODS This was an observational cross-sectional study conducted at a major tertiary teaching hospital in Beirut city. During a 7 months period, patients aged 60 and over and admitted in the medical and surgical units of the hospital were invited to participate in the study. Data were collected by means of a questionnaire including sociodemographic and medical characteristics, the Arabic version of the Mini Nutritional Assessment (MNA), the Activity of Daily Living (ADL) scale, and the American Society of Anesthesiologists (ASA) score. RESULTS 171 participants aged 73.15 ± 8.06 years were included in the study. 52% of them were at risk of malnutrition and 13.5% were malnourished. Prevalence of malnutrition was higher in medical compared to surgical departments (16.2% vs. 10.5%, p = 0.003). Moreover, malnutrition was significantly associated with low level of education, high age, prolonged hospital stay, high number of medical comorbidities, polymedication, high ASA score and low ADL score (p < 0.05). CONCLUSIONS Malnutrition or risk of malnutrition are found in 2 out of 3 hospitalized patients aged 60 years or more, and is associated with several specific risk factors. Screening and management of malnutrition should be considered a priority in order to improve the overall medical status of older people, reduce hospital stay and improve outcome and quality of life.

Abstract
OBJECTIVES The aims of this study were to assess malnutrition risk in Chinese geriatric inpatients using Nutritional Risk Screening 2002 (NRS2002) and Mini-Nutritional Assessment (MNA), and to identify the most appropriate nutritional screening tool for these patients. DESIGN Cross-sectional study. SETTING Eight medical centres in Hubei Province, China. PARTICIPANTS A total of 425 inpatients aged ≥70 years were consecutively recruited between December 2014 and May 2016. PRIMARY AND SECONDARY OUTCOME MEASURES Nutritional risk was assessed using NRS2002, MNA, anthropometric measurements and biochemical parameters within 24 hours of admission. Comorbidities and length of hospitalisation were recorded. Nutritional parameters, body mass index (BMI) and length of hospital stay (LOS) were employed to compare MNA and NRS2002. Kappa analysis was used to evaluate the consistency of the two tools. RESULTS The average age was 81.2±5.9 years (range, 70-98). The prevalence of undernutrition classified by NRS2002 and MNA was 40.9% and 58.6%, respectively. Patients undergoing malnutrition had lower BMI, haemoglobin, albumin and prealbumin (p<0.05), and longer LOS (p<0.05). The NRS2002 showed moderate agreement (κ=0.521, p<0.001) with MNA. Both tools presented significant correlation with age, BMI and laboratory parameters (p<0.001). In addition, a significant association between both tools and LOS was found (p<0.05). In addition, the NRS2002 was not different from MNA in predicting nutritional risk in terms of the area under the receiver operating characteristic curve (p>0.05). CONCLUSIONS The results show a relatively high prevalence of malnutrition risk in our sample cohort. We found that NRS2002 and MNA were both suitable in screening malnutrition risk among Chinese geriatric inpatients.

Abstract
BACKGROUND Older people are more likely to develop nutritional problems and timely diagnosis of malnutrition is crucial to prevent hazardous consequences following poor nutrition. AIMS To evaluate the efficacy of Geriatric Nutritional Risk Index (GNRI) to assess nutritional status among non-hospitalized elderly, compared to mini nutritional assessment (MNA) among Iranian seniors. METHODS One hundred and sixty-four subjects, aged ≥ 65 years old were recruited to our cross-sectional study from various districts of Tabriz (Tabriz, Iran). Anthropometric and biochemical measurements were performed, short- and long-form MNAs and GNRI were assessed in our study subjects. Sensitivity, specificity and predictive values of the three indices, agreement between them, and their correlation with anthropometric and biochemical parameters were evaluated. Receiver-operating characteristic (ROC) curve analysis was performed to determine the optimal cut-off point for GNRI in our study population. RESULTS GNRI had lower sensitivity (50, 57%), but optimal specificity (94, 93%) and lower negative predictive value (NPV; 68, 71%) compared to MNA-LF and MNA-SF, respectively. We found a moderate agreement between GNRI and MNA-SF (K = 0.52) and MNA-LF (K = 0.46) scores. Significant correlations were observed between re-categorized MNAs as well as GNRI scores, and age, weight, MAC, CC, WC, albumin, and pre-albumin. The cut-off point of 110.33 was obtained for GNRI, according to the ROC curve. CONCLUSIONS Although GNRI may not be an efficient tool for screening malnutrition due to its lower sensitivity, it is moderately correlated with MNAs and also more useful when limited funding needs to target the truly malnourished seniors.

Abstract
With the number of individuals older than 65 years expected to rise significantly over the next few decades, dramatic changes to our society and health care system will need to take place to meet their needs. Age-related changes in muscle mass and body composition along with medical comorbidities including stroke, dementia, and depression place elderly adults at high risk for developing malnutrition and frailty. This loss of function and decline in muscle mass (ie, sarcopenia) can be associated with reduced mobility and ability to perform the task of daily living, placing the elderly at an increased risk for falls, fractures, and subsequent institutionalization, leading to a decline in the quality of life and increased mortality. There are a number of modifiable factors that can mitigate some of the muscle loss elderly experience especially when hospitalized. Due to this, it is paramount for providers to understand the pathophysiology behind malnutrition and sarcopenia, be able to assess risk factors for malnutrition, and provide appropriate nutrition support. The present review describes the pathophysiology of malnutrition, identifies contributing factors to this condition, discusses tools to assess nutritional status, and proposes key strategies for optimizing enteral nutrition therapy for the elderly.

Abstract
Malnutrition is very prevalent in geriatric patients with hip fracture. Nevertheless, its importance is not fully recognized. The objective of this paper is to review the impact of malnutrition and of nutritional treatment upon outcomes and mortality in older people with hip fracture. We searched the PubMed database for studies evaluating nutritional aspects in people aged 70 years and over with hip fracture. The total number of studies included in the review was 44, which analyzed 26,281 subjects (73.5% women, 83.6 ± 7.2 years old). Older people with hip fracture presented an inadequate nutrient intake for their requirements, which caused deterioration in their already compromised nutritional status. The prevalence of malnutrition was approximately 18.7% using the Mini-Nutritional Assessment (MNA) (large or short form) as a diagnostic tool, but the prevalence was greater (45.7%) if different criteria were used (such as Body Mass Index (BMI), weight loss, or albumin concentration). Low scores in anthropometric indices were associated with a higher prevalence of complications during hospitalization and with a worse functional recovery. Despite improvements in the treatment of geriatric patients with hip fracture, mortality was still unacceptably high (30% within 1 year and up to 40% within 3 years). Malnutrition was associated with an increase in mortality. Nutritional intervention was cost effective and was associated with an improvement in nutritional status and a greater functional recovery. To conclude, in older people, the prevention of malnutrition and an early nutritional intervention can improve recovery following a hip fracture.

Abstract
BACKGROUND Parenteral nutrition (PN)-dependent adults and elderly individuals who are admitted to hospital treatment are potentially susceptible to mineral disorder complications due to depleted physiological reserves, loss of lean body mass, and increased fat mass, thus worsening inflammation. AIM The purpose of this study is to evaluate the prevalence of hypophosphatemia, hypokalemia, and hypomagnesaemia prior and within the first 7 days of PN infusion. Furthermore, whether malnutrition and old age are associated with these disorders was also investigated. METHODS This study included a historical cohort of adult patients, and 1,040 patients whose information was prospectively entered in the database were evaluated. RESULTS Of the 781 patients, 27.3% were ≥65 years, 80.9% had undergone surgical treatment, 74.3% were in the intensive care unit, and 17.9% died during the hospitalization period. About 17.1% patients were malnourished. Protein energy malnutrition (PEM) was observed in 31.9% of the elderly patients and 27.1% of adults in general. Hypophosphatemia, hypokalemia, and hypomagnesemia were more prevalent before the start of PN infusion (D0: 214 [18.4%]), and new events were more common during the first 2 days of PN infusion (D1: 283 [23.1%]; D2: 243 [20.1%]. Elderly patients were more susceptible to developing hypophosphatemia (odds ratio [OR]: 1.69; 95% confidence interval [CI]: 1.29-2.19; p<0.001). Patients with PEM were also more susceptible to hypophosphatemia (OR: 3.75; 95% CI: 1.13-12.47; p=0.036). CONCLUSION Hypophosphatemia, hypokalemia, and hypomagnesemia were frequently observed in hospitalized adults and elderly patients before and particularly during the first 2 days of PN infusion. Elderly patients and patients with PEM are more susceptible to developing hypophosphatemia.

Abstract
Purpose The increasing number of elderly people worldwide throughout the years is concerning due to the health problems often faced by this population. This review aims to summarize the nutritional status among hospitalized elderly and the role of the nutritional assessment tools in this issue. Methods A literature search was performed on six databases using the terms “malnutrition”, “hospitalised elderly”, “nutritional assessment”, “Mini Nutritional Assessment (MNA)”, “Geriatric Nutrition Risk Index (GNRI)”, and “Subjective Global Assessment (SGA)”. Results According to the previous studies, the prevalence of malnutrition among hospitalized elderly shows an increasing trend not only locally but also across the world. Under-recognition of malnutrition causes the number of malnourished hospitalized elderly to remain high throughout the years. Thus, the development of nutritional screening and assessment tools has been widely studied, and these tools are readily available nowadays. SGA, MNA, and GNRI are the nutritional assessment tools developed specifically for the elderly and are well validated in most countries. However, to date, there is no single tool that can be considered as the universal gold standard for the diagnosis of nutritional status in hospitalized patients. Conclusion It is important to identify which nutritional assessment tool is suitable to be used in this group to ensure that a structured assessment and documentation of nutritional status can be established. An early and accurate identification of the appropriate treatment of malnutrition can be done as soon as possible, and thus, the malnutrition rate among this group can be minimized in the future.

Abstract
This systematic review investigated 5 frequently used nutrition screening tools (NSTs) used in hospitals and their effectiveness at identifying malnutrition risk in the elderly. A literature review was conducted to obtain research articles focused on malnutrition screening in hospitalized elderly and effectiveness of the NST used. Twenty six articles were reviewed and evaluated, resulting in 8 that met inclusion criteria. The Mini Nutritional Assessment-Short Form, designed for use in the elderly, resulted in overestimation of malnutrition. Four screening tools did demonstrate more effectiveness in identifying malnutrition risk; however, several different biochemical and anthropometric parameters were used, which prevented meaningful comparisons. There is a need for a universal NST "gold standard" for use in the elderly, and further research is indicated.

Abstract
Malnutrition is a common yet under-recognized problem in hospitalized patients. The aim of this paper was to systematically review and evaluate malnutrition biomarkers among order adults. Eligible studies were identified through Cochrane, PubMed and the ProQuest Dialog. A meta-regression was performed on concentrations of biomarkers according to malnutrition risks classified by validated nutrition assessment tools. A total of 111 studies were included, representing 52,911 participants (55% female, 72 ± 17 years old) from various clinical settings (hospital, community, care homes). The estimated BMI (p < 0.001) and concentrations of albumin (p < 0.001), hemoglobin (p < 0.001), total cholesterol (p < 0.001), prealbumin (p < 0.001) and total protein (p < 0.05) among subjects at high malnutrition risk by MNA were significantly lower than those without a risk. Similar results were observed for malnutrition identified by SGA and NRS-2002. A sensitivity analysis by including patients with acute illness showed that albumin and prealbumin concentrations were dramatically reduced, indicating that they must be carefully interpreted in acute care settings. This review showed that BMI, hemoglobin, and total cholesterol are useful biomarkers of malnutrition in older adults. The reference ranges and cut-offs may need to be updated to avoid underdiagnosis of malnutrition.

Abstract
BACKGROUND & AIMS Despite the high prevalence of malnutrition among older hospitalized persons, it is unknown how many of these malnourished patients are at risk of developing the refeeding syndrome (RFS). In this study, we sought to compare the prevalence and severity of malnutrition among older hospitalized patients with prevalence of known risk factors of RFS. METHODS This cross-sectional multicenter-study investigated older participants who were consecutively admitted to the geriatric acute care ward. Malnutrition screening was conducted using Nutritional Risk Screening (NRS-2002), Malnutrition Universal Screening Tool (MUST) and Mini Nutritional Assessment-Short Form (MNA-SF). The National Institute for Health and Clinical Excellence (NICE) criteria were applied for assessing patients at risk of RFS. Weight and height were measured. Degree of weight loss (WL) was obtained by interview. Serum phosphate, magnesium, potassium, sodium, calcium, creatinine and urea were analyzed according to standard procedures. RESULTS The study group comprised 342 participants (222 females) with a mean age of 83.1 ± 6.8 and BMI range of 14.7-43.6 kg/m2. More participants were assessed at risk of malnutrition using NRS-2002 (n = 253, 74.0%) compared to MUST (n = 170, 49.7%) and MNA-SF (n = 191, 55.8%). Of total participants, 239 (69.9%; 157 females) were considered to be at risk of RFS. Based on NRS-2002, 75.9% (n = 192) of patients at risk of malnutrition are at risk of RFS whereas according to MUST and MNA-SF, 85.9% (n = 146) and 69.1% (n = 132) of patients at risk of malnutrition are exposed to high risk of RFS, respectively. In addition, the prevalence of risk of RFS is significantly increased with higher score of NRS-2002 and MUST and lower score of MNA-SF. In a stepwise multiple regression analysis, disease severity (38.2%), WL in 3 months (20.3%) and BMI (33.3%) mainly explained variance in NRS-2002, MUST and MNA-SF scores, respectively, in patients with risk of RFS. CONCLUSION Nearly three-quarters of geriatric hospitalized patients with risk of malnutrition demonstrated significant risk of RFS. Therefore, additional screening for risk of RFS in patients screened for malnutrition appears to be abdicable among this population.

Abstract
BACKGROUND Phase angle (PhA) value determined by bioelectrical impedance analysis (BIA) is an indicator of cell membrane damage and body cell mass. Recent studies have shown that low PhA value is associated with increased nutritional risk in various group of patients. However, there have been only a few studies performed globally assessing the relationship between nutritional risk and PhA in hospitalized geriatric patients. The aim of the study is to evaluate the predictive value of the PhA for malnutrition risk in hospitalized geriatric patients. METHODS One hundred and twenty-two hospitalized geriatric patients were included in this cross-sectional study. Comprehensive geriatric assessment tests and BIA measurements were performed within the first 48 h after admission. Nutritional risk state of the patients was determined with NRS-2002. Phase angle values of the patients with malnutrition risk were compared with the patients that did not have the same risk. The independent variables for predicting malnutrition risk were determined. SPSS version 15 was utilized for the statistical analyzes. RESULTS The patients with malnutrition risk had significantly lower phase angle values than the patients without malnutrition risk (p = 0.003). ROC curve analysis suggested that the optimum PhA cut-off point for malnutrition risk was 4.7° with 79.6 % sensitivity, 64.6 % specificity, 73.9 % positive predictive value, and 73.9 % negative predictive value. BMI, prealbumin, PhA, and Mini Mental State Examination Test scores were the independent variables for predicting malnutrition risk. CONCLUSIONS PhA can be a useful, independent indicator for predicting malnutrition risk in hospitalized geriatric patients.

Abstract
Alterations in nutritional status are common and can be associated with increased morbidity and mortality. However, for healthcare providers, the definition of malnutrition is vague, insensitive, and poorly standardized. In contrast, nutrition risk is more easily defined, and recognizes that both poor nutritional status and disease severity contribute to increased morbidity and mortality. Clinicians need to identify patients who may already have evidence of nutrient deficiencies or have disease processes that affect nutrition risk. This article reviews risk assessment tools and provides practical tips to screen patients and identify those whose nutrition risk warrants specialized nutrition therapy.

Abstract
BACKGROUND & AIMS Mortality among patients with chronic heart failure (CHF) is still high despite progress in medical and surgical treatment. The patients' nutritional condition may play an important role, and needs further investigation. The aim of this study was to evaluate whether nutritional risk in hospitalized patients with CHF was associated with three-year mortality. METHODS A prospective study was conducted in 131 hospitalized Norwegian patients with CHF. Nutritional screening was performed using Nutritional Risk Screening (NRS-2002). The primary clinical outcome was death from any cause. RESULTS The prevalence of nutritional risk was 57% (NRS-2002 score ≥ 3). The overall mortality rate was 52.6% within three-year follow up. More patients at nutritional risk (N = 51) died compared to patients not at nutritional risk (N = 18) (P < 0.001). In adjusted analyses patients at nutritional risk had more than five-time higher odds (OR 5.85; 95% CI 2.10-16.24) to die before three-year follow-up than those not at nutritional risk. In adjusted Cox multivariate analysis, the nutritional risk was associated with increased mortality (HR 2.78; 95% CI 1.53-5.03). Furthermore, in adjusted analysis components in NRS-2002 were associated with mortality, i.e. nutritional status (HR 1.82; 95% CI 1.03-3.22), severity of disease (NYHA-class IV) (HR 1.78; 95% CI 1.00-3.16) and age (≥ 70 year) (HR 3.24; 95% CI 1.48-7.10). CONCLUSION Nutritional risk as defined by NRS-2002 in hospitalized patients with CHF was significantly associated with long term mortality.

Abstract
BACKGROUND Adult protein-energy malnutrition (PEM) often occurs in combination with neurological disorders affecting hand use and walking ability. The independent effects of PEM on motor function are not well characterized and may be obscured by these comorbidities. OBJECTIVE Our goal was to undertake a comprehensive evaluation of sensorimotor function with the onset and progression of PEM in an adult male rat model. METHODS In Expt. 1 and Expt. 2, male Sprague-Dawley rats (14-15 wk old) were assigned ad libitum access for 4 wk to normal-protein (NP) or low-protein (LP) diets containing 12.5% and 0.5% protein, respectively. Expt. 1 assessed muscle strength, balance, and skilled walking ability on days 2, 8, and 27 by bar-holding, cylinder, and horizontal ladder walking tasks, respectively. In addition to food intake and body weight, nutritional status was determined on days 3, 9, and 28 by serum acute-phase reactant and corticosterone concentrations and liver lipids. Expt. 2 addressed the effect of an LP diet on hindlimb muscle size. RESULTS PEM evolved over time in rats consuming the LP diet. Total food intake decreased by 24% compared with the NP group. On day 28, body weight and serum albumin decreased by 31% and 26%, respectively, and serum α2-macroglobulin increased by 445% (P < 0.05) in the LP group compared with the NP group. Forelimb dysfunction (173% increase in adaptive flexed-arm-hang score) developed on day 2 in rats fed the LP diet (P < 0.001), whereas abnormal walking (34% decreased incidence of correct hindlimb placement) developed by day 27 (P < 0.05). Relative to the NP diet, the LP diet reduced the cross-sectional area of gastrocnemius medialis (P < 0.05). CONCLUSIONS PEM in adult male rats causes a variety of sensorimotor abnormalities that develop at different stages of malnutrition. This model can be used in combination with disease models of sensorimotor deficits to examine the interactions between nutritional status, other treatments, and disease progression.

Prevalence of nutritional risk in the non-demented hospitalised elderly: a cross-sectional study from Norway using stratified sampling. J Nutr Sci 2015; 4:e18.

Abstract
There is a lack of accurate prevalence data on undernutrition and the risk of
undernutrition among the hospitalised elderly in Europe and Norway. We aimed at estimating
the prevalence of nutritional risk by using stratified sampling along with adequate power
calculations. A cross-sectional study was carried out in the period 2011 to 2013 at a
university hospital in Norway. Second-year nursing students in acute care clinical studies
in twenty hospital wards screened non-demented elderly patients for nutritional risk, by
employing the Nutritional Risk Screening 2002 (NRS2002) form. In total, 508 patients (48·8
% women and 51·2 % men) with a mean age of 79·6 (sd 6·4) years were screened by
the students. Mean BMI was 24·9 (sd 4·9) kg/m2, and the patients had
been hospitalised for on average 5·3 (sd 6·3) d. WHO's BMI cut-off values
identified 6·5 % as underweight, 48·0 % of normal weight and 45·5 % as overweight.
Patients nutritionally at risk had been in hospital longer and had lower average weight
and BMI compared with those not at risk (all P < 0·001); no
differences in mean age or sex were observed. The prevalence of nutritional risk was
estimated to be 45·4 (95 % CI 41·7 %, 49·0) %, ranging between 20·0 and 65·0 % on
different hospital wards. The present results show that the prevalence of nutritional risk
among elderly patients without dementia is high, suggesting that a large proportion of the
hospitalised elderly are in need of nutritional treatment.

Abstract
Albumin is the most abundant plasmatic protein. It is only produced by the liver and the full extent of its metabolic functions is not known in detail. One of the main roles assigned to albumin is as an indicator of malnutrition. There are many factors, in addition to nutrition, that influence levels of albumin in plasma. The main aim of this review is to assess the clinical significance of albumin in elderly people in the community, in hospital and in care homes. Following the review, it can be stated that age is not a cause of hypoalbuminemia. Albumin is a good marker of nutritional status in clinically stable people. Significant loss of muscle mass has been observed in elderly people with low albumin levels. Hypoalbuminemia is a mortality prognostic factor in elderly people, whether they live in the community or they are in hospital or institutionalized. Low levels of albumin are associated to worse recovery following acute pathologies. Inflammatory state and, particularly, high concentrations of IL-6 and TNF-alpha, are two of the main influencing factors of hypoalbuminemia. In elderly patients with a hip fracture, albumin levels below 38 g/L are associated to a higher risk of post-surgery complications, especially infections. Further research is needed on the impact of nutritional intervention upon albumin levels and on the outcomes in elderly people in the community, in hospital and in care.

Abstract
OBJECTIVE Few data is available on the nutritional status of old Chinese. The present study aimed to describe the nutritional status and clinical correlates for malnutrition risk in the older people. DESIGN Cross-sectional study. SETTING Hospital- and community-based older people were recruited in the region of Chongqing, China. PARTICIPANTS 558 individuals aged 60 years old or over between April 2011 and October 2012. MEASUREMENTS Comprehensive geriatric assessment was performed and nutritional status was assessed by the Mini Nutritional Assessment Short Form (MNA-SF). Nutrition-associated factors were analyzed, including health status (chronic diseases, depression, cognition, function impaired), social factors (education status, marital status, the type of work before 60 years old) and life style factors (smoking, drinking, diet). RESULTS The mean age was 73.1±8.0 years and 43.9% were men. Prevalence of malnutrition and risk for malnutrition were 3.2% and 19.3 %, respectively. Several factors increased poor nutrition independently including self-rated health, comorbidity, chronic obstructive pulmonary disease, gastrointestinal disease and cognitive impairment. Fish decreased the risk of poor nutrition. CONCLUSIONS The prevalence was relatively low in older people of Chongqing, Southwest China. Poor nutrition was found to be increased due to the common health problems. Thus the patients with these problems should pay more attention on nutritional status. The older people should often have fish because of their nutritional benefit.

Abstract
Nutritional deficiencies are independent risk factors for adverse outcomes in patients with nervous system disease. Patients with nervous system disease can often become malnourished due to swallowing difficulties or unconsciousness. This malnourishment increases hospitalization duration; average total hospital cost; occurrence of infection, pressure ulcers, and other complications. These problems need to be addressed in the clinic. In this paper, we review the relevant literature, including studies on influencing factors, evaluations, indexes, and methods: Our aim is to understand the current status of malnutrition in patients with nervous system disease and reasons associated with nutritional deficiencies by using malnutrition evaluation methods to assess the risk of nutritional deficiencies in the early stages.

Abstract
Retinol-binding protein (RBP) has been used as a nutritional index for children with acute myeloid leukaemia (AML) in previous studies. However, no studies have yet examined RBP levels in AML patients from all age groups. In this study, AML patients presented with lower RBP concentrations than healthy control subjects and patients with benign haematopathies. A negative association was observed between serum RBP level and peripheral white blood cell count in M4 and M5 AML patients. Moreover, patients carrying the FLT3-ITD mutation and young patients had lower RBP levels than those lacking this mutation and elderly patients. In conclusion, these observations suggest that aberrant retinol levels may be associated with AML.

Abstract
Age is becoming less of a consideration to aggressive medical and surgical interventions. The aim of this study was to evaluate whether patients older than 80 years showed similar gains from total parenteral nutrition (TPN) in terms of nutritional and inflammatory markers compared to patients 35 to 50 years old. A database of patients aged ≥80 years old (group 1) and patients between 35 and 50 (group 2), on TPN for greater than 1 week, was compiled from the Nutrition Support Service (NSS) database. Patients had C-reactive protein (CRP), prealbumin, and albumin drawn twice weekly. Patients were matched 1:1 based on gender, diabetes, smoking, Subjective Global Assessment score, and diagnosis. Both groups showed comparable improvements in nutritional and inflammatory markers. There were no statistically significant differences in weekly changes to prealbumin, albumin, CRP, and CRP:prealbumin (C:P) ratio between group 1 and group 2 patients. Both groups had similar complication rates (line-related thrombosis, catheter-related bloodstream infections, intra-abdominal sepsis), days on TPN, length of hospitalization, and mortality rate. Patients older than 80 years benefit from aggressive nutritional support by administration of TPN. Age should not be used as an exclusion criterion for patients requiring TPN.

Abstract
The aim of the present study was to evaluate the Mini Nutritional Assessment (MNA), the Nutritional Risk Screening (NRS) 2002 and the American Society of Anesthesiologists Physical Status Score (ASA) as predictors of gait status and mortality 6 months after hip fracture. A total of eighty-eight consecutive patients over the age of 65 years with hip fracture admitted to an orthopaedic unit were prospectively evaluated. Within the first 72 h of admission, each patient's characteristics were recorded, and the MNA, the NRS 2002 and the ASA were performed. Gait status and mortality were evaluated 6 months after hip fracture. Of the total patients, two were excluded because of pathological fractures. The remaining eighty-six patients (aged 80·2 (sd 7·3) years) were studied. Among these patients 76·7 % were female, 69·8 % walked with or without support and 12·8 % died 6 months after the fracture. In a multivariate analysis, only the MNA was associated with gait status 6 months after hip fracture (OR 0·773, 95 % CI 0·663, 0·901; P= 0·001). In the Cox regression model, only the MNA was associated with mortality 6 months after hip fracture (hazard ratio 0·869, 95 % CI 0·757, 0·998; P= 0·04). In conclusion, the MNA best predicts gait status and mortality 6 months after hip fracture. These results suggest that the MNA should be included in the clinical stratification of patients with hip fracture to identify and treat malnutrition in order to improve the outcomes.

Abstract
PURPOSE OF REVIEW To summarize recent evidences and advances on the implementation and the use of the Mini Nutritional Assessment (MNA). RECENT FINDINGS Despite being introduced and validated for clinical use about 20 years ago, the MNA has recently received new attention in order to more widely disseminate among healthcare professionals the practice of a systematic nutritional screening and assessment of the old patient. Particularly, the structure has been implemented to face the difficulties in having the patients contributing to the assessment and to reduce further the time required to complete the evaluation. Recent data also confirm that in older populations prevalence of malnutrition by this tool is associated with the level of dependence. The rationale of nutritional assessment is to identify patients candidate to nutritional support. However, the sensitivity of the MNA is still debated because it has been associated with a high-risk 'overdiagnosis' and the advantages of a positive screening need to be assessed both in terms of outcome and money saving. SUMMARY The MNA is a simple and highly sensitive tool for nutritional screening and assessment. The large mass of data collected and the diffusion among healthcare professionals clearly support its use. However, the cost-effectiveness of interventions based on its scoring deserves investigation.

Abstract
AIM The aim of this study was to compare the nutritional biochemical parameters, prealbumin levels, and bioimpedance analysis parameters of adult and elderly hemodialysis (HD) patients. METHODS This prospective cross-sectional study included 50 adult HD patients (42.0 % female). Nutritional status was assessed by post-dialysis multifrequency bioimpedance analysis (BIA), serum prealbumin and other nutritional biochemical parameters. RESULTS Mean age of patients was 57.4±15.1 years (range: 30-83 years) and mean dialysis duration was 68.3 ± 54.5 months (range: 3-240 months). When the patients were divided into two groups according to age of patients (<65 and ≥65), prealbumin (p=0.003), blood urea nitrogen (BUN) (p=0.000), serum creatinine (p=0.013), albumin (p=0.016), protein catabolic rate per normalized body weight (nPCR) (p=0.001), intracellular water (ICW)/total body weight (0.003) , body fat mass (p00.000), lean body mass (p=0.031), lean dry mass (p=0.001), illness marker (p=0.005), basal metabolism (p=0.007), body mass index (BMI) (p=0.028), body fat mass index (BFMI) (p=0.000), fat free mass index (FFMI) (p=0.040) values were significantly different between the groups. In the elderly patients (age ≥65), body fat mass, illness marker, BMI, BFMI were higher compared to adult patients (age <65). Additionally, in the elderly patients, prealbumin, BUN, creatinine, albumin, nPCR, ICW/ total body weight, lean body weight, lean dry weight, basal metabolism and FFMI were lower than adult patients. CONCLUSIONS Our results indicate that BFMI were higher, albumin, prealbumin, nPCR and lean body mass and FFMI were lower in elderly patients compared to adults. These results imply that elderly HD patients may be prone sarcopenic obesity and may require special nutritional support.
