Supportive care for systemic amyloidosis: International Society of Amyloidosis (ISA) expert panel guidelines

Systemic amyloidosis refers to a group of protein misfolding disorders resulting in organ deposition with amyloid, leading to organ dysfunction, ultimately resulting in organ failure and death if not successfully treated. Treatment is type-specific and aimed at the underlying source of the misfolded protein. In the past decades, treatments have become increasingly available across the various amyloidosis types with improved response rates and longer survival. Supportive care measures are an integral part of care for patients with systemic amyloidosis to improve symptom burden and quality of life, reduce healthcare costs, and potentially prolong survival while type-directed therapy takes effect. In these guidelines, we provide supportive care recommendations across eight areas of interest in systemic amyloidosis: cardiology, nephrology, peripheral neuropathy, central nervous system involvement, autonomic neuropathy, gastroenterology, coagulopathy and bleeding, nutrition and hematology. These guidelines were developed on behalf of the International Society of Amyloidosis (ISA) by experts in the above fields and provide the best available evidence and expertise for supportive care in these rare disorders.

Evaluating the effect of nutritional support in geriatric inpatients classified by the GLIM criteria

OBJECTIVES

In this study, we aimed to explore the impact of nutrition therapy on clinical outcomes for patients classified according to the Global Leadership Initiative on Malnutrition (GLIM) criteria.

DESIGN

Prospective, multicenter cohort study.

SETTING

This study was conducted from September 2020 to December 2022 across 28 geriatric centers in China.

PARTICIPANTS

A total of 862 patients aged ≥65 years were included.

INTERVENTION

All participating physicians completed a 6-h training on nutritional support, following international guidelines before the study. Patients had a nutritional risk screening 2002 score ≥3 points within 48 h of admission. Physicians determined specific nutritional support regimens.

MEASUREMENTS

GLIM assessments were conducted after enrollment. Nutritional and functional statuses were evaluated at baseline and 90 days after admission. Clinical outcomes-mortality, readmission, new infections, and falls-were documented after 90 days.

RESULTS

Compared to 108 patients without malnutrition per the GLIM criteria, 754 malnourished patients showed lower weight, body mass index (BMI), and Mini Nutritional Assessment-Short Form (MNA-SF) scores and significant reductions in grip strength, calf circumference, and Barthel activities of daily living (ADLs) index. The percentage of patients with adequate caloric intake at the 90-day follow-up was 70.7% (n = 533) and 67.6% (n = 73) in the malnutrition and non-malnutrition groups (p = 0.51) and that of patients with adequate protein intake was 65.9% (n = 497) and 58.3% (n = 63), respectively (p = 0.12). Moreover, malnourished patients showed significant improvements in body weight, BMI, MNA-SF scores, calf circumference, and Barthel ADL index compared to those without malnutrition. Malnourished patients also had lower risks of readmission and falls at follow-up.

CONCLUSION

Among older inpatients at nutritional risk, those with malnutrition classified according to the GLIM criteria benefited from nutritional support, demonstrating improved BMI, MNA-SF scores, calf circumference, and Barthel ADL index, as well as reduced readmission rates and incidence of falls.

Evaluating repeated handgrip strength measurements as predictors of mortality in malnourished hospitalized patients. Secondary analysis of a randomized controlled trial

BACKGROUND

Handgrip strength (HGS) is a simple yet effective bed-side tool for assessing muscle strength, which plays an important role in clinical evaluation and monitoring. We hypothesize that repeated measurements of HGS during the hospital stay may serve as a reliable and robust indicator of clinical course and outcomes.

METHODS

We re-analyzed data from 565 out of 2028 patients who had repeated handgrip measurement (on admission and on day 7) included in EFFORT, a Swiss-wide multicenter, randomized controlled trial comparing individualized nutritional support with usual care nutrition in medical inpatients. The primary endpoint was 180-day all-cause mortality.

RESULTS

The mean change in HGS from baseline to day 7 was 0.6 kg (SD 4.2) in female and 0.7 kg (SD 3.7) in male patients. Patients with a positive HGS trend had a lower risk of dying within 180 days compared to patients without a positive trend (mortality 11.4% vs. 25.4%, adjusted HR 0.45 [95% CI 0.27 to 0.77], p = 0.003). The change in HGS was also associated with the nutritional intake during the hospitalization in male patients: those who met their energy and protein targets were twice as likely to have an increase in HGS during hospitalization (adjusted OR 2.05 [95% CI 1.23 to 3.42], p = 0.006).

CONCLUSIONS

Achieving nutritional targets was associated with a short-term increase in HGS during hospitalization, and a positive HGS trend was associated with a lower risk of mortality after 180 days. These data provide evidence that repeated HGS measurements are a robust bedside tool for assessing and monitoring patients receiving nutritional therapy in the hospital.

The Nutritional Phenotyping of Idiopathic Pulmonary Fibrosis Through Morphofunctional Assessment: A Bicentric Cross-Sectional Case-Control Study

There is increasing evidence supporting the use of morphofunctional assessment (MFA) as a tool for clinical characterization and decision-making in malnourished patients. MFA enables the diagnosis of malnutrition, sarcopenia, obesity, and cachexia, leading to a novel phenotype-based classification of nutritional disorders. Bioelectrical impedance analysis (BIVA), nutritional ultrasound® (NU) and computed tomography (CT) are included, along with functional tests like the Timed Up and Go test (TUG). Myoesteatosis, detectable via CT, can occur independently from nutritional phenotypes and has been identified as a significant mortality predictor in idiophatic pulmonary fibrosis (IPF). Our aim is to analyze the prevalence and overlap of nutritional phenotypes in IPF and evaluate the prognostic value of myoesteatosis. Our bicenter cross-sectional study included 82 IPF patients (84.1% male and with a medium age of 71.1 ± 7.35 years). MFA was performed using BIVA, NU, CT at the T12 level (CT-T12), the handgrip strength (HGS) test, and the TUG. CT-T12 BC parameters were analyzed using FocusedON® software, while statistical analyses were conducted with JAMOVI version 2.3.22. All four major nutritional phenotypes were represented in our cohort, with significant overlap. A total of 80.5% met the GLIM criteria for malnutrition, 14.6% had cachexia, 17% were sarcopenic, and 28% were obese. Of the obese patients, 70% were also malnourished, while 100% of sarcopenic obese patients (5.9% of total) had malnutrition. A total of 55% of sarcopenic patients with available CT also had myosteatosis, suggesting muscle quality deterioration as a potential driver of functional impairment. The presence of myosteatosis > 15% in T12-CT was an independent predictor of 12-month mortality (HR = 3.13; 95% CI: 1.01-9.70; p = 0.049), with survival rates of 78.1% vs. 96.6% in patients with vs. without myosteatosis, respectively. To conclude, this study underscores the relevance of MFA in the nutritional characterization of patients with IPF, demonstrating its potential to identify specific phenotypes associated with malnutrition, functional impairment, and the presence of myoesteatosis, thereby providing a valuable tool for clinical decision-making.

Evidence Summary of Early Enteral Nutrition Support for Adult Patients with Extracorporeal Membrane Oxygenation (ECMO)

Objective

This study aims to systematically review and summarize the evidence on early enteral nutrition (EEN)support for Extracorporeal Membrane Oxygenation (ECMO)patients, Offer evidence-based guidance to healthcare professionals, including doctors and nurses, to inform their clinical practices.

Methods

Using the "6S"evidence-based model, we searched multiple databases including UpToDate, Best Practice, Guideline International Network (GIN), National Guideline Clearinghouse (NGC),Registered Nurses' Association of Ontario (RNAO), Joanna Briggs Institute (JBI), Evidence-Based Healthcare Center database, the Cochrane Library, PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI),Wanfang Database, and Chinese Biomedical Literature Database (CBM). Aiming to find evidence on early enteral nutrition support for adult patients with extracorporeal membrane oxygenation. The search included clinical decisions, guidelines, systematic reviews, evidence summaries, and expert consensus. The time frame for the search was from the inception of the databases to September 10, 2024.Two researchers evaluated the quality of the collected literature and extracted data and summarized evidence from publications that met the quality criteria.

Results

We retrieved 13 relevant documents, consisting of 6 guidelines, 3 expert consensus papers, 2 clinical decision-making articles, and 2 cohort studies. Through summarization and induction, a total of 26 best evidence pieces were obtained across five aspects: the establishment of nutritional support plans; strategies and risk assessment for enteral nutrition; the implementation of early enteral nutrition supplementation strategies; the amount and composition of nutrients reaching standard intake; and prevention of enteral nutrition-related complications.

Conclusion

This study has summarized the evidence regarding early enteral nutrition support for adult patients with extracorporeal membrane oxygenation (ECMO). It provides an evidence-based foundation for the practice of nursing and assists medical staff in developing personalized nutrition management plans for enteral nutrition support in ECMO patients.

Implementation of evidence-based clinical nutrition: Usability of the new digital platform clinicalnutrition.science

AIM OF THE STUDY

Malnutrition is a common and complex challenge in inpatient and outpatient settings, associated with increased risk of morbidity and mortality. Its management is often neglected, despite strong evidence of the benefits of adequate nutritional therapy. We introduced clinicalnutrition.science (https://clinicalnutrition.science/en/), a digital platform that provides healthcare professionals with easy online access to evidence and streamlines the nutritional care process. The aim of this study was to assess the usability and to validate improvements in nutritional management when the digital platform is used by healthcare professionals.

METHODS

The usability study, conducted from 28 September to 16 November 2023, involved 56 healthcare professionals from the University Hospital of Bern and the Cantonal Hospital of Aarau. In an adapted cross-over study design, participants completed key steps of nutritional management for a simulated hepatology and oncology case both with and without the clinicalnutrition.science platform. Usability was assessed using the validated Healthcare Systems Usability Scale questionnaire, supplemented by collection of demographic data. Subgroup analysis was performed for recommended protein and energy intakes by different professional representatives.

RESULTS

Clinicalnutrition.science achieved a good overall usability score of 71.8%. Use of the platform significantly improved the protein intake recommendation (p = 0.03; median 96.5 and 80.0 g/d) and the basal metabolic rate estimate (p <0.01; median 1420.8 and 1755.5 kcal/d) of the simulated oncology case. The variance in protein and energy intake recommendations, basal metabolic rate estimation and energy deficit estimation was reduced by using the digital platform. These improvements were achieved without increasing the time required to complete key steps in nutritional management for the two patient cases (median between 10.5 and 15.0 minutes; p = 0.09 and p = 0.67) and without prior training on the platform. There was no effect on the malnutrition detection rate, the selection of an appropriate nutritional product or the identification of the most appropriate guideline.

CONCLUSIONS

The use of clinicalnutrition.science improved evidence-based clinical practice in prescribing personalised nutritional therapy and increased the accuracy of both protein and energy intake recommendations, without increasing the time taken to complete key steps in the nutritional management process.

A novel appetite loss in older adults with and without cognitive impairment (ALOC) screening scale

Appetite is a strong determinant of nutritional status. As cognitive impairment is usually linked to alterations in eating behaviour, people with dementia might experience changes in appetite with the loss of ability to express their needs, including dietary choices and preferences. The aim of the study was to develop an appetite loss screening tool for older adults, inclusive for those with mild to moderate cognitive impairment. The study questionnaire, consisting of 44 binary items related to appetite, was employed among 127 hospitalized older patients (55.9% women, mean age 79.4 ± 7.1 years) with and without cognitive impairment (31.5% categorized as suspected mild dementia, 26.0% as suspected moderate dementia). An exploratory factor analysis was performed to identify items that constitute the final scale, with a Cronbach's alpha coefficient of 0.81. The final tool consists of seven questions, with a sensitivity of 80% and specificity of 80.6%, using the Council on Nutrition Appetite Questionnaire score as reference. Acceptability post-test was performed in 20 patients (70% women, mean age 79.6 ± 5.3 years) to test the clinical feasibility of the scale. The customized design of the scale, according to the recommendation for written materials for individuals with dementia, empowers older adults, supports diagnosis and encourages their proactivity in the treatment process. The scale was found to perform similarly in older persons with and without cognitive impairment, which renders it a versatile assessment tool.

Nutritional gap after transfer from the intensive care unit to a general ward - A retrospective quality assurance study

BACKGROUND

Adequate nutrition is important for recovery after critical illness. Even so, our knowledge of patients' nutritional intake after intensive care unit (ICU) discharge is scarce.

OBJECTIVES

We aimed to explore nutritional planning and achieved nutritional intake in ICU patients who transfer from the ICU to general wards.

METHODS

A retrospective quality assurance study.

INCLUSION CRITERIA

adult ICU patients transferring to a general ward at Copenhagen University Hospital-Herlev from May to August 2021. Primary outcomes were as follows: having a nutritional plan on the day of ICU transfer. A nutritional plan was defined as follows: (i) individual assessment of energy and protein requirement; (ii) intake, documented as achieved percentage of energy and protein requirements; (iii) prescribed type of nutrition. If using enteral or parenteral nutrition; (iv) the prescribed doses; and (v) the prescribed product. Secondary outcomes were as follows: achieved percentage of energy and protein requirements from day -1 before ICU transfer until day +1 and day +3 after ICU transfer.

RESULTS

We included 57 patients; the mean age was 64 years (±11.1); 43 (75%) patients were male; the median ICU stay was 6 days (interquartile range: 3-11). One (2%) patient had a full nutritional plan according to listed criteria. Patients' median percentage of requirements met declined significantly from the day before to the day after ICU discharge (energy: from 94% to 30.5%; p = 0.0051; protein: from 73% to 27.5%; p = 0.0117). The decline in percentage of requirements met remained unchanged from day 1 to 3 after ICU transfer.

CONCLUSIONS

In conclusion, few patients had a nutritional plan when transferring from the ICU to a general ward. After ICU discharge, percentage of energy and protein requirements met declined significantly and remained insufficient during the first 3 days at the general ward.

Validation of GLIM criteria for hospital malnutrition diagnosis by comparison of three different anthropometric approaches to evaluate reduced muscle mass: a prospective cohort study

Background and aim

The Global Leadership Initiative on Malnutrition (GLIM) recently proposed a new malnutrition diagnostic tool known as the GLIM criteria. The GLIM criteria need confirmed validation before being widely used in each population or healthcare system. This study aimed to investigate the validation of the GLIM criteria for malnutrition diagnosis in hospitalized patients.

Methods

The content validity was assessed by calculating the content validity ratio (CVR) and content validity index (CVI). Subjective global assessment (SGA) is considered the reference tool to diagnose malnutrition in concurrent validation. In addition, the Kuder-Richardson 20 was used to evaluate the reliability of the GLIM criteria. Furthermore, hospital mortality, length of hospitalization (LOS), prolonged hospital stays (LOS >6 days), 30-day hospital readmission, and 30- and 60-day mortality were identified as malnutrition-related outcomes in predictive validity.

Results

A total of 332 adult/elderly hospitalized patients (median age: 58 (IQR: 24.7), 60.5% men) were enrolled to present the study. Appling GLIM criteria by considering the calf circumference < 31 cm in both genders or mid-upper arm (MUAC) < 23 cm in men and MUAC <22 cm in women as reduced muscle mass had an appropriate accuracy (84.6 and 83.4%, respectively), good ability to distinguish malnourished patients (AUC ROC: 0.85 and 0.83, respectively), satisfactory sensitivity (89.58 and 84.02%, respectively), and satisfactory specificity (81 and 83%, respectively) compared to the SGA tool. Furthermore, the reliability of the GLIM criteria for malnutrition diagnosis in hospitalized patients was acceptable in all 3 applied approaches (KR-20 > 0.5). The malnutrition diagnosed by GLIM criteria could significantly predict the odds of prolonged hospital stays, 30-day hospital readmission, and 60-day mortality, while it had no significant association with the risk of hospital mortality.

Conclusion

The current study revealed that applying GLIM criteria had satisfactory validity in diagnosing hospital malnutrition in non-critically ill hospitalized patients.

Two-step GLIM approach using NRS-2002 screening tool vs direct GLIM criteria application in hospital malnutrition diagnosis: A cross-sectional study

BACKGROUND

The two-step Global Leadership Initiative on Malnutrition (GLIM) approach was recently introduced to malnutrition diagnosis in a hospital setting. This study compares the diagnostic performance of this approach that uses the Nutritional Risk Screening-2002 (NRS-2002) as a screening tool and the direct application of GLIM malnutrition diagnostic criteria in hospitalized patients.

METHODS

This cross-sectional study involved 290 adult and older adult patients who were hospitalized. A trained nutritionist implemented the two-step GLIM approach, including NRS-2002 (in the first step) and GLIM criteria (in the second step) for each patient. Then, the accuracy, kappa index, area under the receiver operating characteristic curve (AUC ROC), sensitivity, and specificity of malnutrition diagnostic performance of the two-step GLIM approach and NRS-2002 were evaluated compared to the direct use of GLIM criteria.

RESULTS

The NRS-2002 identified 145 (50.0%) patients as at risk of malnutrition. The prevalence of malnutrition using the two-step GLIM approach and GLIM malnutrition diagnosis criteria were 120 (41.4%) and 141 (48.6%), respectively. The kappa index showed substantial and almost perfect agreement for NRS-2002 (κ = 68%) and the two-step GLIM approach (κ = 85%) with GLIM malnutrition diagnostic criteria, respectively. Furthermore, the AUC ROC (0.926; 95% confidence interval (CI): 0.89-0.96) and accuracy (92.8%) of the two-step GLIM approach compared to the GLIM criteria indicated an acepptable ability to distinguish between malnourished and well-nourished patients.

CONCLUSION

The two-step GLIM approach using NRS-2002 as a screening tool (in step one) had acceptable malnutrition diagnostic performance compared to the direct application of GLIM criteria in hospitalized patients.

Sex differences in clinical presentation, treatment response, and side effects of nutritional therapy among patients at nutritional risk: a secondary analysis of the randomized clinical trial EFFORT

BACKGROUND

Considering sex-specific factors has become an increasingly recognized area for research and practice, in the field of clinical nutrition, there is insufficient evidence regarding differences in clinical presentation, treatment response, and side effects of nutritional therapy among female and male patients.

OBJECTIVES

We hypothesized that the clinical presentation, response to nutritional therapy, and side effects from the intervention would differ in the two sexes.

METHODS

This secondary analysis investigated differences among female and male patients at risk for malnutrition regarding initial presentation, clinical outcomes, and treatment response in patients included in the Effect of Early Nutritional Support on Frailty, Functional Outcomes, and Recovery of Malnourished Medical Inpatients Trial (EFFORT), a randomized controlled trial comparing individualized nutritional support to usual care.

RESULTS

Of 2028 patients included in the trial, 964 were females and 1064 were males. The nutritional history and clinical presentation of female patients was different: they consumed less food and had a greater loss of appetite than the male population. Male patients had higher risk for mortality at 180 d [27% compared with 19%; adjusted hazards ratio (HR): 1.35; 95% CI: 1.12, 1.63] and further adverse clinical outcomes. However, there was no difference in the effect of nutritional support on mortality among female and male patients (HR: 0.76; 95% CI: 0.45, 1.27, compared with HR: 0.81; 95% CI: 0.54, 1.21, respectively; P-interaction = 0.939).

CONCLUSIONS

Results of this multicenter randomized trial suggest that multimorbid female inpatients have a different clinical presentation and are more prone to loss of appetite and reduced daily dietary intake than male inpatients. Importantly, the favorable response to nutritional interventions was similar in both sexes. This trial was registered at clinicaltrials.gov as NCT02517476.

Antipsychotic, benzodiazepine and Z-drug prescriptions in a Swiss hospital network in the Choosing Wisely and COVID-19 eras: a longitudinal study

AIMS OF THE STUDY

Physicians frequently prescribe antipsychotics off-label to treat, among others, insomnia and anxiety. The Swiss "smarter medicine - Choosing Wisely" campaign has tried to raise awareness about the risks and to limit benzodiazepine and Z-drug prescriptions. In the Italian-speaking part of Switzerland, our network of public hospitals joined the campaign with the aim of avoiding unnecessary benzodiazepine and Z-drug treatments, with prescription monitoring, benchmarking and educational contributions. Considering the risks of a possible shift towards the prescription of antipsychotics, and aware of the potential role of the COVID-19 pandemic, we decided to analyse the prescription trends of antipsychotics and benzodiazepines/Z-drugs before, during (2016-2017) and after the intervention.

METHODS

For this longitudinal study, we reactivated a continuous monitoring of inpatient benzodiazepine/Z-drug and antipsychotics prescriptions/deprescriptions, paused in 2018 after the end of the internal Choosing Wisely campaign, based on routinely collected observational health data. We screened all demographic, administrative and prescription data of patients admitted to the internal medicine department of the four teaching hospitals (H1-H4) belonging to the EOC (Ente Ospedaliero Cantonale) network, from the fourth quarter of 2014 to the second quarter of 2023.

RESULTS

We analysed 74,659 hospital stays (14,645 / 16,083 / 24,285 / 19,646 at hospitals H1 / H2 / H3 / H4 respectively). The mean (± SD) case mix (a metric that reflects the diversity, complexity and severity of the treated patients) and patient age were 1.08 ± 0.14 and 73 ± 2 years. 10.6% and 12.1% of patients received antipsychotics prior to admission and at discharge respectively (new prescriptions 3.3 ± 0.7%; deprescriptions 13.3 ± 5.2%). New prescriptions showed an upward trend, with +0.20% per year (p <0.001). Patients admitted with ongoing antipsychotics therapy increased 0.36% per year (p <0.001). New benzodiazepine/Z-drug prescriptions showed a 0.20% per year decrease (p = 0.01). Patients admitted with ongoing benzodiazepine/Z-drug therapy decreased 0.32% per year (p <0.001). New antipsychotics prescriptions showed differences between hospitals, with H3 above and H2 below the average.

CONCLUSIONS

The increase in antipsychotics quantitatively matched the decrease in benzodiazepine/Z-drug prescribing, suggesting a shift from one to the other sedative therapy. The same trend was visible in the ongoing prescriptions at admission revealing a similar out-of-hospital approach. This suggests a change in sedative prescribing strategy rather than the choice of alternative, non-pharmacological approaches. Furthermore, the variation between similar services of different hospitals points out the consequences of local prescribing cultures and the importance of continuously monitoring and benchmarking medication prescriptions.

Significant Published Articles in 2023 for Pharmacy Nutrition Support Practice

Purpose: The purpose of this article is to assist the pharmacist engaged in nutrition support therapy in staying current with pertinent literature. Methods: Several board-certified nutrition support pharmacists aggregated a list of articles relevant to pharmacy nutrition support published in 2023. The list was compiled into a spreadsheet whereby the authors were asked to assess whether the article was considered important. A culled list of publications was then identified whereby at least 5 out of the 8 author participants considered the article to be important for pharmacists practicing in nutrition support. Guideline and consensus papers, important to practice but not ranked, were also included. Results: A total of 133 articles were identified; 9 from the primary literature were voted by the group to be of high importance. Fourteen guidelines, position, recommendation, or consensus papers were also identified. The top-ranked articles from the primary literature were summarized and a narrative regarding its implications to pharmacy nutrition support practice were provided. Conclusion: We recommend that pharmacists engaged in nutrition support therapy be familiar with these articles as it pertains to their practice.

Trends and development in perioperative enteral nutrition: a systematic bibliometric analysis

BACKGROUND

This research aims to explore the intellectual landscape of studies in perioperative enteral nutrition (PEN) and identify trends and research frontiers in the field.

METHODS

Scientometric research was conducted through the analysis of bibliographic records from the Web of Science Core Collection Database for the period 2014-2023. Analyses performed using CiteSpace software included cooperation network analysis, reference co-citation analysis, and keywords co-occurrence analysis.

RESULTS

The analysis included 3,671 valid records in the final dataset. Findings indicate an upward trend in annual publications, with the United States leading in research output and Harvard University as the top publishing institution. The Journal of Parenteral and Enteral Nutrition was identified as the most productive journal. Notable research hotspots include enhanced recovery after surgery, early enteral nutrition, intestinal failure, short bowel syndrome, abdominal surgery. Evidence-based articles have emerged as the predominant literature type. Future research trends are anticipated to focus on gut microbiota and patients with congenital heart disease.

CONCLUSION

Our study provides a comprehensive analysis of the publication volume, contributions by country/region and institutions, journal outlets, and reference and keyword clusters in the field of PEN over the decade. The findings provide valuable insights for researchers, policymakers, and clinicians, helping them comprehend the research landscape, identify gaps, and shape future research directions in this field.

The Association of the Essential Amino Acids Lysine, Methionine, and Threonine with Clinical Outcomes in Patients at Nutritional Risk: Secondary Analysis of a Randomized Clinical Trial

Lysine, methionine, and threonine are essential amino acids with vital functions for muscle and connective tissue health, metabolic balance, and the immune system. During illness, the demand for these amino acids typically increases, which puts patients at risk for deficiencies with harmful clinical consequences. In a secondary analysis of the Effect of Early Nutritional Support on Frailty, Functional Outcomes, and Recovery of Malnourished Medical Inpatients Trial (EFFORT), which compared individualized nutritional support to usual care nutrition in patients at nutritional risk, we investigated the prognostic impact of the lysine, methionine, and threonine metabolism. We had complete clinical and amino acid data in 237 patients, 58 of whom reached the primary endpoint of death at 30 days. In a model adjusted for comorbidities, sex, nutritional risk, and trial intervention, low plasma methionine levels were associated with 30-day mortality (adjusted HR 1.98 [95% CI 1.16 to 3.36], p = 0.01) and with a decline in functional status (adjusted OR 2.06 [95% CI 1.06 to 4.01], p = 0.03). The results for lysine and threonine did not show statistically significant differences regarding clinical outcomes. These findings suggest that low levels of methionine may be critical during hospitalization among patients at nutritional risk. Further studies should investigate the effect of supplementation of methionine in this patient group to improve outcomes.

LLL 44 - Module 3: Micronutrients in Chronic disease

Micronutrients (MN), i.e. trace elements and vitamins, are essential organic molecules, which are required in the diet in relatively small amounts in any form of nutrition (oral, enteral, parenteral). The probability of MN depletion or deficiencies should be considered in all chronic illnesses, especially in those that can interfere with intake, digestion, or intestinal absorption. Low socio-economic status and food deprivation are recognized as the most prevalent reasons for MN deficiencies world-wide. Elderly multimorbid patients with multimodal therapy, as well as patients with long-lasting menu restrictions, are at high risk for both disease related malnutrition as well as multiple MN deficiencies, needing careful specific follow-up. The importance of monitoring MN blood levels along with CRP is essential for optimal care. Drug interactions are also highlighted. In patients with chronic conditions depending on medical nutrition therapy, the provision of adequate dietary reference intakes (DRI) of MN doses and monitoring of their adequacy belongs to standard of care.

A Novel Machine-Learning Algorithm to Predict the Early Termination of Nutrition Support Team Follow-Up in Hospitalized Adults: A Retrospective Cohort Study

BACKGROUND

For hospitalized adults, it is important to initiate the early reintroduction of oral food in accordance with nutrition support team guidelines. The aim of this study was to develop and validate a machine learning-based algorithm that predicts the early termination of medical nutritional therapy (the transition to oral feeding).

METHODS

This retrospective cohort study included consecutive adult patients admitted to the Hacettepe hospital (from 1 January 2018 to 31 December 2022). The outcome of the study was the prediction of an early transition to adequate oral feeding before discharge. The dataset was randomly (70/30) divided into training and test datasets. We used six ML algorithms with multiple features to construct prediction models. ML model performance was measured according to the accuracy, area under the receiver operating characteristic curve, and F1 score. We used the Boruta Method to determine the important features and interpret the selected features.

RESULTS

A total of 2298 adult inpatients who were followed by a nutrition support team for medical nutritional therapy were included. Patients received parenteral nutrition (1471/2298, 64.01%), enteral nutrition (717/2298, 31.2%), or supplemental parenteral nutrition (110/2298, 4.79%). The median (interquartile range) Nutritional Risk Screening (NRS-2002) score was 5 (1). Six prediction algorithms were used, and the artificial neural network and elastic net models achieved the greatest area under the ROC in all outcomes (AUC = 0.770). Ranked by z-value, the 10 most important features in predicting an early transition to oral feeding in the artificial neural network and elastic net algorithms were parenteral nutrition, surgical wards, surgical outcomes, enteral nutrition, age, supplemental parenteral nutrition, digestive system diseases, gastrointestinal complications, NRS-2002, and impaired consciousness.

CONCLUSIONS

We developed machine learning models for the prediction of an early transition to oral feeding before discharge. Overall, there was no discernible superiority among the models. Nevertheless, the artificial neural network and elastic net methods provided the highest AUC values. Since the machine learning model is interpretable, it can enable clinicians to better comprehend the features underlying the outcomes. Our study could support personalized treatment and nutritional follow-up strategies in clinical decision making for the prediction of an early transition to oral feeding in hospitalized adult patients.

Prevalence and Impact of Malnutrition Risk on Outcomes in Critically Ill Patients with Traumatic Brain Injury and Stroke: A Retrospective Cohort Study Using Electronic Health Records

BACKGROUND

Malnutrition is a critical concern in ICU settings. It is associated with increased morbidity and mortality, yet its prevalence and impact on clinical outcomes in patients with stroke and traumatic brain injury (TBI) remain underexplored.

OBJECTIVE

To evaluate the prevalence and impact of malnutrition risk on clinical outcomes in ICU patients with TBI, ischemic stroke, and hemorrhagic stroke, and to identify key risk factors associated with malnutrition risk.

METHODS

This retrospective cohort study utilized electronic health records encompassing ICU admissions from 2017 to 2023. Patients with either stroke or TBI were included, with malnutrition risk assessed using the prognostic nutritional index. Data were extracted and analyzed to determine patient characteristics, clinical and laboratory parameters, and outcomes.

RESULTS

This study included 1352 patients (267 TBI, 825 ischemic stroke, and 260 hemorrhagic stroke patients, >30% with pneumonia at admission). Severe malnutrition risk at admission was observed in over 60% of patients. Stroke patients, particularly those with hemorrhagic stroke, exhibited a higher risk of malnutrition compared to TBI patients. Malnutrition risk was associated with significantly higher hospital mortality and increased need for mechanical ventilation. Predictive factors for malnutrition risk included advanced age, higher SOFA scores, lower FOUR and GCS scores, and the presence of pneumonia at admission.

CONCLUSIONS

Risk of malnutrition is highly prevalent among ICU patients with TBI, ischemic, and hemorrhagic stroke, significantly impacting mortality and other clinical outcomes. Identifying and managing malnutrition early in the ICU setting is crucial for improving patient outcomes. Further prospective, multicenter studies are needed to validate these findings and develop effective interventions.

A Prospective, Observational Study of the Effect of a High-Calorie, High-Protein Oral Nutritional Supplement with HMB in an Old and Malnourished or at-Risk-of-Malnutrition Population with Hip Fractures: A FracNut Study

BACKGROUND

Hip fractures are prevalent among older people, often leading to reduced mobility, muscle loss, and bone density decline. Malnutrition exacerbates the prognosis post surgery. This study aimed to evaluate the impact of a 12-week regimen of a high-calorie, high-protein oral supplement with β-hydroxy-β-methylbutyrate (HC-HP-HMB-ONS) on nutritional status, daily activities, and compliance in malnourished or at-risk older patients with hip fractures receiving standard care.

SUBJECTS AND METHODS

A total of 270 subjects ≥75 years of age, residing at home or in nursing homes, malnourished or at risk of malnutrition, and post hip fracture surgery, received HC-HP-HMB-ONS for 12 weeks. Various scales and questionnaires assessed outcomes.

RESULTS

During the 12 weeks of follow-up, 82.8% consumed ≥75% of HC-HP-HMB-ONS. By week 12, 62.4% gained or maintained weight (+0.3 kg), 29.2% achieved normal nutritional status (mean MNA score +2.8), and 46.8% improved nutritional status. Biochemical parameters improved significantly. Subjects reported good tolerability (mean score 8.5/10), with 87.1% of healthcare providers concurring.

CONCLUSIONS

The administration of HC-HP-HMB-ONS markedly enhanced nutritional status and biochemical parameters in older hip-fracture patients, with high compliance and tolerability. Both patients and healthcare professionals expressed satisfaction with HC-HP-HMB-ONS.

S3-Leitlinie Heimenterale und heimparenterale Ernährung der Deutschen Gesellschaft für Ernährungsmedizin (DGEM)

Medizinische Ernährungstherapie, die enterale und parenterale Ernährung umfasst, ist ein wesentlicher Teil der Ernährungstherapie. Medizinische Ernährungstherapie beschränkt sich nicht auf die Krankenhausbehandlung, sondern kann effektiv und sicher auch zu Hause eingesetzt werden. Dadurch hat sich der Stellenwert der Medizinischen Ernährungstherapie deutlich erhöht und ist zu einem wichtigen Bestandteil der Therapie vieler chronischer Erkrankungen geworden. Für Menschen mit chronischem Darmversagen, z. B. wegen Kurzdarmsyndrom ist die Medizinische Ernährungstherapie sogar lebensrettend. In der Leitlinie wird die Evidenz für die Medizinische Ernährungstherapie in 161 Empfehlungen dargestellt. Die Leitlinie wendet sich in erster Linie an Ärzte, Ernährungsfachkräfte und Pflegekräfte, sie dient der Information für Pharmazeuten und anderes Fachpersonal, kann aber auch für den interessierten Laien hilfreich sein.

ESPEN practical guideline: Nutritional support for polymorbid medical inpatients

BACKGROUND

Disease-related malnutrition in polymorbid medical inpatients is a highly prevalent syndrome associated with significantly increased morbidity, disability, short- and long-term mortality, impaired recovery from illness, and healthcare costs.

AIM

As there are uncertainties in applying disease-specific guidelines to patients with multiple conditions, our aim was to provide evidence-based recommendations on nutritional support for the polymorbid patient population hospitalized in medical wards.

METHODS

The 2023 update adheres to the standard operating procedures for ESPEN guidelines. We undertook a systematic literature search for 15 clinical questions in three different databases (Medline, Embase and the Cochrane Library), as well as in secondary sources (e.g., published guidelines), until July 12th, 2022. Retrieved abstracts were screened to identify relevant studies that were used to develop recommendations (including SIGN grading), which was followed by submission to Delphi voting. Here, the practical version of the guideline is presented which has been shortened and equipped with flow charts for patients care.

RESULTS

32 recommendations (7× A, 11× B, 10× O and 4× GPP), which encompass different aspects of nutritional support were included from the scientific guideline including indication, route of feeding, energy and protein requirements, micronutrient requirements, disease-specific nutrients, timing, monitoring and procedure of intervention. Here, the practical version of the guideline is presented which has been shortened and equipped with flow charts for patients care.

CONCLUSIONS

Recent high-quality trials have provided increasing evidence that nutritional support can reduce morbidity and other complications associated with malnutrition in polymorbid patients. The timely screening of patients for risk of malnutrition at hospital admission followed by individualized nutritional support interventions for at-risk patients should be part of routine clinical care and multimodal treatment in hospitals worldwide. Use of this updated practical guideline offers an evidence-based nutritional approach to polymorbid medical inpatients and may improve their outcomes.

Adaptation of nutritional risk screening tools may better predict response to nutritional treatment: a secondary analysis of the randomized controlled trial Effect of early nutritional therapy on Frailty, Functional Outcomes, and Recovery of malnourished medical inpatients Trial (EFFORT)

BACKGROUND

Nutritional screening tools have proven valuable for predicting clinical outcomes but have failed to determine which patients would be most likely to benefit from nourishment interventions. The Nutritional Risk Screening 2002 (NRS) and the Mini Nutritional Assessment (MNA) are 2 of these tools, which are based on both nutritional parameters and parameters reflecting disease severity.

OBJECTIVES

We hypothesized that the adaptation of nutritional risk scores, by removing parameters reflecting disease severity, would improve their predictive value regarding response to a nutritional intervention while providing similar prognostic information regarding mortality at short and long terms.

METHODS

We reanalyzed data of 2028 patients included in the Swiss-wide multicenter, randomized controlled trial EFFORT (Effect of early nutritional therapy on Frailty, Functional Outcomes, and Recovery of malnourished medical inpatients Trial) comparing individualized nutritional support with usual care nutrition in medical inpatients. The primary endpoint was 30-d all-cause mortality.

RESULTS

Although stratifying patients by high compared with low NRS score showed no difference in response to nutritional support, patients with high adapted NRS showed substantial benefit, whereas patients with low adapted NRS showed no survival benefit [adjusted hazard ratio: 0.55 [95% confidence interval (CI): 0.37, 0.80]] compared with 1.17 (95% CI: 0.70, 1.93), a finding that was significant in an interaction analysis [coefficient: 0.48 (95% CI: 0.25, 0.94), P = 0.031]. A similar effect regarding treatment response was found when stratifying patients on the basis of MNA compared with the adapted MNA. Regarding the prognostic performance, both original scores were slightly superior in predicting mortality than the adapted scores.

CONCLUSIONS

Adapting the NRS and MNA by including nutritional parameters only improves their ability to predict response to a nutrition intervention, but slightly reduces their overall prognostic performance. Scores dependent on disease severity may best be considered prognostic scores, whereas nutritional risk scores not including parameters reflecting disease severity may indeed improve a more personalized treatment approach for nourishment interventions. The trial was registered at clinicaltrials.gov as NCT02517476.

Dysphagia as a primary manifestation of basilar impression: A case report

Secondary basilar invagination or basilar impression is an anomaly at the craniovertebral junction where the odontoid process prolapses into the foramen magnum with the risk of compressing adjacent structures and obstructing the proper flow of cerebrospinal fluid (CSF). The incidence is less than 1% in the general population and occurs mainly in the first three decades of life when it is associated with malformations of the neuroaxis. In older age, the main aetiologies are diseases that alter bone mineral density. The clinical course is usually progressive and the most common symptoms are asthenia, cervical pain and restricted movement, but also dysphonia, dyspnoea and dysphagia. It is a progressive disease which, if left untreated, can cause severe neurological damage and death. We report the case of a 79-year-old woman with osteoporosis and progressive dysphagia leading to severe malnutrition, which conditioned the decision not to intervene due to the high perioperative risk.

Red blood cell distribution width (RDW) - A new nutritional biomarker to assess nutritional risk and response to nutritional therapy?

BACKGROUND & AIMS

Red cell distribution width (RDW) has been proposed as a surrogate marker for acute and chronic diseases and may be influenced by nutritional deficits. We assessed the prognostic value of RDW regarding clinical outcomes and nutritional treatment response among medical inpatients at nutritional risk.

METHODS

This is a secondary analysis of EFFORT, a randomized, controlled, prospective, multicenter trial investigating the effects of nutritional support in patients at nutritional risk in eight Swiss hospitals. We examined the association between RDW and mortality in regression analysis.

RESULTS

Among 1,244 included patients (median age 75 years, 46.6 % female), high RDW (≥15 %) levels were found in 38 % of patients (n = 473) with a significant association of higher malnutrition risk [OR 1.48 (95%CI 1.1 to 1.98); p = 0.009]. Patients with high RDW had a more than doubling in short-term (30 days) mortality risk [adjusted HR 2.12 (95%CI 1.44 to 3.12); p < 0.001] and a signficant increase in long-term (5 years) mortality risk [adjusted HR 1.73 (95%CI 1.49 to 2.01); p < 0.001]. Among patients with high RDW, nutritional support reduced morality within 30 days [adjusted OR 0.56 (95%CI 0.33 to 0.96); p = 0.035], while the effect of the nutritional intervention in patients with low RDW was markedly smaller.

CONCLUSIONS

Among medical patients at nutritional risk, RDW correlated with several nutritional parameters and was a strong prognostic marker for adverse clinical outcomes at short- and long-term, respectively. Patients with high baseline RDW levels also showed a strong benefit from the nutritional intervention. Further research is needed to understand whether monitoring of RDW over time severs as a nutritional biomarker to assess effectiveness of nutritional treatment in the long run.

Human Nutrition Research in the Data Era: Results of 11 Reports on the Effects of a Multiple-Micronutrient-Intervention Study

Large datasets have been used in molecular and genetic research for decades, but only a few studies have included nutrition and lifestyle factors. Our team conducted an n-of-1 intervention with 12 vitamins and five minerals in 9- to 13-year-old Brazilian children and teens with poor healthy-eating indices. A unique feature of the experimental design was the inclusion of a replication arm. Twenty-six types of data were acquired including clinical measures, whole-genome mapping, whole-exome sequencing, and proteomic and a variety of metabolomic measurements over two years. A goal of this study was to use these diverse data sets to discover previously undetected physiological effects associated with a poor diet that include a more complete micronutrient composition. We summarize the key findings of 11 reports from this study that (i) found that LDL and total cholesterol and fasting glucose decreased in the population after the intervention but with inter-individual variation; (ii) associated a polygenic risk score that predicted baseline vitamin B12 levels; (iii) identified metabotypes linking diet intake, genetic makeup, and metabolic physiology; (iv) found multiple biomarkers for nutrient and food groups; and (v) discovered metabolites and proteins that are associated with DNA damage. This summary also highlights the limitations and lessons in analyzing diverse omic data.

Nutrition Care after Hospital Discharge in Singapore: Evidence-Based Best-Practice Recommendations

The nutritional status of hospitalised patients is often at risk or compromised and predisposed to further deterioration after discharge, leading to poor clinical outcomes, high healthcare costs, and poor quality of life. This paper aims to provide evidence-based best-practice recommendations to address this, supported by a national survey of healthcare professionals in Singapore and reviewed by a multidisciplinary expert panel under the Sarcopenia Interest Group of Society of Parenteral and Enteral Nutrition Singapore (SingSPEN). We advocate screening all patients with a validated tool which includes a disease activity/burden component, an easily accessible dietitian referral pathway for patients at risk of malnutrition, and an individualised nutrition care plan formulated and delivered using a multidisciplinary team approach for patients at risk or with malnutrition. A comprehensive team would include not only dietitians but also physicians, nurses, physiotherapists, speech therapists, and medical social workers working together towards a common goal. Information on why nutrition is important for good health and how it can be achieved should also be provided to all patients and their caregivers before and after hospital discharge. With the above recommendations, we seek to improve upon the current nutrition care processes at discharge for healthcare institutions in Singapore.
