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.

The kidney: the critical organ system for guiding nutrition therapy in the ICU-patient?

Most randomized controlled studies on nutrition in intensive care patients did not yield conclusive results or were neutral or negative concerning the primary endpoints but also in most secondary endpoints. However, there is a consistent observation that in several of these studies there was a negative effect of the nutrition intervention on the kidneys in one of the study arms. During the early phase and in unstable periods during further course of disease an inadequate clinical nutrition can damage the kidneys, can elicit or aggravate acute kidney injury and/ or increase requirements of renal replacement therapy (RRT). This relates to total energy intake, glucose intake/hyperglycemia and protein/ amino acid intake at various stages of renal dysfunction. The kidney could present a critical organ system for guiding nutrition therapy, a close monitoring of kidney function should be observed and nutrition therapy may need to be adapted accordingly. The long-held dogma of performing full nutrition and accept an otherwise not necessary RRT is definitely to be refuted.

Trimodal prehabilitation in oncogynaecology.

Prehabilitation is a set of interventions aimed at increasing the patient's endurance and functional capacity before a planned stressful event (oncogynaecological surgery). Currently, prehabilitation is based on three main modalities which are: physiotherapy, nutritional support and psychological support, with others gradually being added. In studies published to date, a positive effect of combined preoperative intervention on the patient's postoperative recovery reduces the risk of perioperative and postoperative complications, shortening the hospital stay. This directly reduces the costs associated with cancer treatment.

Nutritional support in pancreatic cancer patients and its effect on nutritional status: an observational regional HPB network study investigating current practice.

PURPOSE: Preoperative malnutrition is associated with poor postoperative outcomes in patients with pancreatic cancer. This study evaluated the effectiveness of current practice in nutritional support for patients with pancreatic cancer. METHODS: Observational multicenter HPB network study conducted at the Isala Clinics Zwolle, Medical Spectrum Twente, Medical Center Leeuwarden, and University Medical Center Groningen between October 2021 and May 2023. Patients with a suspected pancreatic malignancy scheduled for surgery were screened for malnutrition using the Patient-Generated Subjective Global Assessment (PG-SGA) questionnaire and referred to a dedicated dietician for nutritional support comprising pancreatic enzyme replacement therapy, dietary advice, and nutritional supplements to achieve adequate caloric and protein intake. At baseline, 1 day preoperatively, and 3 months postoperatively, the nutritional status and muscle thickness were evaluated. RESULTS: The study included 30 patients, of whom 12 (40%) classified as malnourished (PG-SGA ≥ 4) at baseline. Compared to well-nourished patients, malnourished patients were younger, were predominantly female, and had a higher body mass index, despite having lost more body weight in the past 6 months. All malnourished patients and 78% of the well-nourished patients received nutritional support. Consequently, a preoperative increase in caloric and protein intake and body weight were observed. Postoperatively, despite a further increase in caloric intake, a considerable decrease in protein intake, body weight, and muscle thickness was observed. CONCLUSION: Malnutrition is prevalent in patients undergoing pancreatic surgery. Nutritional support by a dedicated dietician is effective in enhancing patients' preoperative nutritional status. However, postoperative monitoring of adequate nutritional intake in patients could be improved.

The predictive value of GLIM criteria on clinical outcomes and responses to nutritional support in patients with neurocritical illnesses.

Neurocritically ill patients frequently exhibit coma, gastroparesis, and intense catabolism, leading to an increased risk of malnutrition. The Global Leadership Initiative on Malnutrition (GLIM) criteria for the diagnosis of malnutrition was created to achieve a consistent malnutrition diagnosis across diverse populations. This study aimed to validate the concurrent and predictive validity of GLIM criteria in patients with neurocritical illnesses. A total of 135 participants were followed from admission to the neurocritical unit (NCU) until discharge. Comparing GLIM criteria to the Subjective Global Assessment (SGA), sensitivity was 0.95 and specificity was 0.69. Predictive validity of GLIM criteria was assessed using a composite adverse clinical outcome, comprising mortality and various major complications. Adjusted hazard ratios for moderate and severe malnutrition were 2.86 (95% CI 1.45-5.67) and 3.88 (95% CI 1.51-9.94), respectively. Changes in indicators of nutritional status, including skeletal muscle mass and abdominal fat mass, within 7 days of admission were obtained for 61 participants to validate the predictive capability of the GLIM criteria for the patients' response of standardized nutritional support. The GLIM criteria have a statistically significant predictive validity on changes in rectus femoris muscle thickness and midarm muscle circumference. In conclusion, the GLIM criteria demonstrate high sensitivity for diagnosing malnutrition in neurocritically ill patients and exhibit good predictive validity.

Barriers and facilitators of improved nutritional support for patients newly diagnosed with cancer: a pre-implementation study.

BACKGROUND: Disease-related malnutrition affects a significant number of patients with cancer and poses a major social problem worldwide. Despite both global and national guidelines to prevent and treat malnutrition, the prevalence is high, ranging from 20 to 70% in all patients with cancer. This study aimed to explore the current practice of nutritional support for patients with cancer at a large university hospital in Norway and to explore potential barriers and facilitators of the intervention in the Green Approach to Improved Nutritional support for patients with cancer (GAIN), prior to implementation in a clinical setting. METHODS: The study used individual interviews and a focus group discussion to collect data. Study participants included different healthcare professionals and patients with cancer treated at a nutrition outpatient clinic. The Consolidated Framework for Implementation Research (CFIR) was used to guide the thematic data analysis. RESULTS: Barriers connected to the current nutritional support were limited resources and undefined roles concerning responsibility for providing nutritional support among healthcare professionals. Facilitators included a desire for change regarding the current nutritional practice. The GAIN intervention was perceived as feasible for patients and healthcare professionals. Potential barriers included limited knowledge of technology, lack of motivation among patients, and a potential added burden experienced by the participating patients. CONCLUSIONS: The identification of the potential barriers and facilitators of the current nutritional support to patients with cancer will be used to plan the implementation of improved nutritional support in a randomized controlled trial for patients with cancer prior to clinical implementation. The current findings may be of value to others trying to implement either or both nutritional support and digital application tools in a clinical healthcare setting. TRIAL REGISTRATION: The study was registered in the National Institutes of Health Clinical trials 08/09/22. The identification code is NCT05544318.

[Nutritional status and nutritional support of patients with chronic disorders of consciousness at the stage of medical rehabilitation].

Chronic disturbances of consciousness (CDC) are a consequence of severe brain damage and are conditions that arise after emerging from a coma with the preservation of the sleep-wake cycle in the absence of signs of conscious behavior. When conducting inpatient medical rehabilitation of this group of patients, the state of nutritional status is not always taken into account and, as a rule, there is no nutritional support with an assessment of metabolic needs, including the introduction of various modes of physical activity during physical therapy and an increase in physical load on the patient's body. The purpose of the study was to assess the nutritional status and optimize the nutritional support system in patients with CDC at the inpatient stage of medical rehabilitation (MR). Material and methods. The study analyzed the results of examination and treatment of 152 patients with CDC of traumatic origin who received medical rehabilitation from 2016 to 2022 in the Department of Physical and Rehabilitation Medicine of the Nikiforov Russian Center of Emergency and Radiation Medicine, Ministry of Russian Federation for Civil Defense, Emergencies and Elimination of Consequences of Natural Disasters. Results. In patients with CDC of traumatic genesis, signs of malnutrition (objective, anthropometric, laboratory) were diagnosed at the inpatient stage of MR, and there were also risks of malnutrition progression with the introduction of additional physical activity. Conclusion. To create an effective and adequate nutritional support system during inpatient MR, metabolic monitoring (indirect calorimetry) is of fundamental importance, taking into account the influence of additional physical activity. The use of a calculation method for estimating energy requirements can lead to hyperalimentation.

Nutritional Prehabilitation in Patients Undergoing Abdominal Surgery-A Narrative Review.

Malnutrition plays a crucial role as a risk factor in patients undergoing major abdominal surgery. To mitigate the risk of complications, nutritional prehabilitation has been recommended for malnourished patients and those at severe metabolic risk. Various approaches have been devised, ranging from traditional short-term conditioning lasting 7-14 days to longer periods integrated into a comprehensive multimodal prehabilitation program. However, a significant challenge is the considerable heterogeneity of nutritional interventions, leading to a lack of clear, synthesizable evidence for specific dietary recommendations. This narrative review aims to outline the concept of nutritional prehabilitation, offers practical recommendations for clinical implementation, and also highlights the barriers and facilitators involved.

The Effect of Protein Nutritional Support on Inflammatory Bowel Disease and Its Potential Mechanisms.

Inflammatory bowel disease (IBD), a complex chronic inflammatory bowel disorder that includes Crohn's disease (CD) and Ulcerative Colitis (UC), has become a globally increasing health concern. Nutrition, as an important factor influencing the occurrence and development of IBD, has attracted more and more attention. As the most important nutrient, protein can not only provide energy and nutrition required by patients, but also help repair damaged intestinal tissue, enhance immunity, and thus alleviate inflammation. Numerous studies have shown that protein nutritional support plays a significant role in the treatment and remission of IBD. This article presents a comprehensive review of the pathogenesis of IBD and analyzes and summarizes the potential mechanisms of protein nutritional support in IBD. Additionally, it provides an overview of the clinical effects of protein nutritional support in IBD and its impact on clinical complications. Research findings reveal that protein nutritional support demonstrates significant benefits in improving clinical symptoms, reducing the risk of complications, and improving quality of life in IBD patients. Therefore, protein nutritional support is expected to provide a new approach for the treatment of IBD.

Nutrition therapy in non-intubated patients with acute respiratory failure: a narrative review.

Objectives: Non-invasive ventilation use is increasing in patients from acute respiratory failure. However, nutritional assessment and medical nutritional therapy are often missed and patients may be frequently underfed. This review evaluates the tools for nutritional screening and assessment, assesses the use of medical nutritional therapy in various techniques of non invasive ventilation and suggested tools to improve this therapy. Methods, results: A review of the literature was performed to evaluate the tools available to define malnutrition and determine the energy needs of patients requiring non invasive ventilation. Energy and protein intake was assessed in 16 recent papers. High Flow Nasal Cannula Oxygen therapy and non invasive ventilation using mask were described and nutritional therapy determined in each condition.The Global Leadership International Malnutrition Assessment seems to be the best assessment to be recommended. Energy expenditure is optimally obtained by indirect calorimetry. Patients with Non invasive ventilation are even more underfed than patients receiving High Flow Nasal Cannula Oxygen therapy. Conclusions: A better determination of malnutrition, a more adequate energy requirement and an improved energy and protein administration are required in patients with acute respiratory failure treated with non invasive ventilation.

The ethics of clinically assisted nutrition and hydration in adults and the role of the advanced clinical practitioner.

Clinically assisted nutrition and hydration (CANH) decision-making in adult patients presents complex ethical dilemmas that require careful consideration and navigation. This clinical review addresses the multifaceted aspects of CANH, emphasising the importance of ethical frameworks and the role of advanced clinical practitioners (ACPs) in guiding decision-making processes. The pivotal role of ACPs is highlighted, from their responsibilities and challenges in decision-making to the collaborative approach they facilitate involving patients, families and multidisciplinary teams. The article also explores ethical principles such as autonomy, beneficence, non-maleficence, and justice, elucidating their application in CANH decision-making. Legal and ethical frameworks covering CANH are examined, alongside case studies illustrating ethical dilemmas and resolutions. Patient-centred approaches to CANH decision-making are discussed, emphasising effective communication and consideration of cultural and religious beliefs. End-of-life considerations and palliative care in CANH are also examined, including the transition to palliative care and ethical considerations in withdrawal or withholding of CANH. Future directions for research and implications for clinical practice are outlined, highlighting the need for ongoing ethical reflection and the integration of ACPs in CANH decision-making.

Approaches to nutrition and feeding in congenital diaphragmatic hernia.

In patients with congenital diaphragmatic hernia1, nutrition can represent a challenge both in the short and long term. Its failure to resolve can have a significant impact on multiple aspects of the lives of patients with congenital diaphragmatic hernia (CDH), ranging from lung function to neurodevelopment. In this review, we will describe the causes of nutritional problems in patients with CDH, their consequences, and possible strategies to address them.

Impact of various nutritional interventions on the physical and mental state of patients undergoing surgery for oral and maxillofacial tumor: guiding patients' informed choices.

PURPOSE: To compare the effects of oral nutritional supplements (ONS), parenteral nutrition (PN), and enteral nutrition (EN) on the recovery of patients who underwent oral and maxillofacial surgery. METHODS: The shared decision-making process assigned 37, 56, and 35 patients to the ONS, PN, and EN groups, respectively. Details such as demographic data, duration of hospitalization, cost of nutritional therapy, nutritional assessments, patients' satisfaction, and compliance, Hamilton Anxiety Rating Scale (HAM-A) score, and relevant biochemical indices were systematically recorded and compared between the groups. RESULTS: Patients with healthier biochemical indices and physical states at baseline, including a higher body mass index, preferred ONS. Patients using dentures and those with medical insurance often chose EN, while patients with recurrent disease preferred PN. Patients receiving EN had a similar duration of hospitalization to patients receiving ONS and also had the lowest nutritional costs. Patients receiving ONS had higher lymphocyte counts and levels of hemoglobin, albumin, and C-reactive protein. Patients in the PN group had elevated levels of serum potassium, chlorine, and sodium, while those receiving EN reported higher HAM-A scores, indicating greater anxiety than their counterparts. Predischarge surveys showed higher satisfaction and compliance in the PN and ONS groups than in the EN group. The PN group reported more adverse symptoms. At 7 days post-discharge, patients with EN reported a greater feeling of well-being. CONCLUSION: ONS is the optimal choice for patients in good preoperative conditions, while PN is preferred during disease recurrence or when financially feasible. EN is suitable for patients using dentures or those with limited finances despite its potential psychological discomfort. Future studies with increased sample sizes and longer follow-up duration are necessary to corroborate our findings. The Trial Registration Number is ChiCTR2100049547.

Systemic Inflammation in Oncologic Patients Undergoing Systemic Treatment and Receiving Whey Protein-Based Nutritional Support.

There is increasing evidence about the role of inflammation in sarcopenia and tumor progression; thus, its modulation would represent a valuable strategy for improving clinical outcomes in patients with cancer. Several studies have reported that whey protein has significant anti-inflammatory and antioxidant characteristics in humans. We aimed to evaluate the effects of whey protein-based oral nutritional support on circulating cytokines in patients with solid tumors undergoing systemic treatment. Forty-six patients with solid tumors of different origin and undergoing systemic treatment were evaluated. Nutritional support with two daily whey protein-based oral supplements was administered. Circulating levels of IL-6, IL-8, IL-10, MCP-1 and IP-10 were determined. Nutritional evaluation included anthropometric, instrumental and biochemical parameters. Over 63% of the evaluated patients underwent surgery, 56.5% required chemotherapy and almost 50% received combined treatment. Patients with resected primary tumor presented with lower baseline IL-6 (p < 0.05) and IP-10 (p < 0.001); after three months of nutritional support, they presented with lower IL-8 (p < 0.05) and tended to present lower IL-6 and IP-10 (p = 0.053 and 0.067, respectively). Significant positive correlations between circulating cytokines, C-reactive protein and ferritin were observed; similarly, negative correlations with anthropometric and biochemical nutritional parameters were noticed (p < 0.05). We did not observe significant changes in circulating cytokine levels (IL-6, IL-8, IL-10, MCP-1 and IP-10) in patients with cancer undergoing systemic treatment after three months of nutritional support with whey protein-based oral supplements. According to a univariate analysis in our cohort, circulating IL-8 was associated with mortality in these patients, additionally, MCP-1 and IP-10 tended to correlate; but an age- and sex-adjusted multivariate analysis revealed that only baseline MCP-1 was significantly associated with mortality (OR 1.03 (95% CI: 1.00-1.05)). In conclusion, surgery of the primary solid tumor and combination treatment allow significant reduction in circulating cytokine levels, which remained stable while patients received nutritional support with whey protein-based oral supplements over three months. The role of MCP-1 as an independent factor for mortality in these patients should be further evaluated.

Effects of protein-enriched nutritional support on skeletal muscle mass and rehabilitative outcomes in brain tumor patients: a randomized controlled trial.

Patients with brain tumors require extensive and prolonged rehabilitation efforts as they suffer from lesion-induced motor weakness as well as treatment-related side effects, often leading to a significant decline in function. Protein supplements have shown positive effects on promoting muscle strength and physical performance in various tumor etiologies. However, reports on their effects specifically in brain tumor patients remain scarce. This study aims to investigate the feasibility and efficacy of protein supplements in enhancing rehabilitative outcomes via muscle strengthening and functional gain in brain tumor patients with neurological demise. Sixty brain tumor patients were randomly assigned to either a protein supplement or a control group, receiving either protein supplements or a placebo for 6 weeks, in conjunction with conventional rehabilitation therapy. Assessments before and after the intervention included laboratory tests, anthropometric measures using bioimpedance analysis, and functional assessments, which included the MMSE, the modified Barthel Index, the Beck Depression Inventory, the Brief Fatigue Inventory, the Timed Up and Go test, the 6-min walk test, the isokinetic quadriceps muscle strength test, and the handgrip power. After the intervention, the levels of serum hemoglobin, protein, albumin, and C-reactive protein were improved in both groups, however, the change was significant only in the protein group. The muscle strength was enhanced in both groups, however, the significant increase in pinch grasp power was only noted in the protein group (P < 0.05). The distance on 6MWT was also significantly extended at follow-up in the protein group (P < 0.01). In the subgroup analysis according to nutritional status, the moderate malnutrition group showed greater augmentation of muscle mass than those with adequate nutrition (P < 0.05). Interestingly, the amelioration of malnutrition was observed only the in protein group. This study using protein supplements to promote the rehabilitative potential of brain tumor patients revealed a significant effect on improving hemodynamic nutritional indices, muscle power reimbursement, and functional improvement, especially in malnourished patients. The safety and feasibility of protein supplements in brain tumor patients were affirmative in this study. Further studies with more patients may help confirm the secondary functional gain resulting from increased muscle power.Trial registration: This study was retrospectively registered in the Clinical Research Information Service, CRIS no. KCT0009113 on Jan 12, 2024.
