In advanced cancer, the benefits of nutritional interventions are less clear, with no consensus about effectiveness. This uncertainty is compounded by the heterogeneity of nutritional interventions and absence of cohesive, evidence-based approaches. Intervention diversity highlights the need to summarize current dietary and nutritional approaches and their evidence base. <b>Objective:</b> To map and summarize the current evidence base for nutritional interventions in advanced cancer. <b>Methods:</b> A systematic search included studies on nutritional interventions in adults with advanced cancer, excluding enteral/parenteral nutrition. Five databases (CINAHL Ultimate, Embase, Medline, SCOPUS, Web of Science) were searched from inception until 10/20/2023. Four researchers undertook screening and data extraction. Due to the heterogeneous nature of the studies, data synthesis was narrative. <b>Results:</b> The databases search yielded 3290 records. Fifty additional publications were identified through manual searches. Title/abstract screening identified 253 articles for full-text screening, 35 of which met inclusion criteria. Of these, 25 (69%) were randomized controlled trials. The studies were separated into 5 themes: (1) nutraceutical and herbal interventions, (2) ketogenic diet, (3) nutrition advice/support, (4) oral nutrition supplements, (5) other nutritional interventions. Outcome measures reported included anthropometry, biological markers, feasibility, performance status, quality of life, survival, and treatment tolerability. Most provided information about weight and energy intake and a few reported lean body mass. Although some reported positive outcomes, evidence is insufficient for definitive recommendations for any of those interventions. <b>Conclusions:</b> Our scoping review provided limited evidence for various nutritional interventions and dietary approaches. Dietary advice and oral nutritional supplements sometimes appeared to enhance treatment tolerance and improve nutritional status; impact on overall survival was inconsistent. Nutraceutical and herbal interventions showed limited clinical benefits despite apparent biological activity. The variability in outcomes underscores the need for personalized nutritional strategies that consider individual patient factors.</p>","PeriodicalId":94222,"journal":{"name":"The American journal of hospice & palliative care","volume":" ","pages":"668-688"},"PeriodicalIF":1.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144045020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Long-term postoperative opioid use is a clinically useful indicator of recovery. Few studies have developed machine learning models to predict this outcome in spinal metastatic disease patients.MethodsThe Merative™ Marketscan® Commercial Database and Medicare Supplement were analyzed to identify adult patients who underwent surgery for extradural spinal metastatic disease between 2006 and 2023. Patients were required to have at least 6 months of continuous preadmission data, and 6 months of continuous post-discharge follow-up. The primary outcome was prolonged opioid use, defined as filling a perioperative prescription followed by another between 90- and 180-days post-discharge. Cumulative days of postoperative opioid supply was assessed as a secondary outcome. Five models (stochastic gradient boosting, support vector machine, neural network, random forest and penalized logistic regression) were trained on a 70% training sample and validated on the withheld 30%.ResultsA total of 732 patients were included, of which 341 (46.6%) had prolonged post-discharge opioid use.

A lab-designed NFRF bed sensor recorded cardiopulmonary waveforms. Recorded video enabled minute-level Respiratory Distress Observation Scale scoring as reference.

ML classifiers (eg, random forest, k-nearest neighbors) were evaluated using 5-fold cross-validation, and class imbalance was addressed through data augmentation.ResultsTen patient-legally authorized representative dyads were enrolled.
