Survival of individuals with neurological and oncological diseases receiving home enteral nutrition: A descriptive cohort study.

Epidemiologyenteral nutritionhealth servicesepidemiology
Clinical takeawayRisk-stratify HEN patients using age, comorbidity burden, diagnosis type (neurological vs. oncological), functional status, and tube type to personalize counseling and monitoring intensity. High-risk patients (older, multiple comorbidities, male, nasogastric tube, oncological disease) warrant more intensive monitoring and family counseling regarding expected prognosis.
What it foundIn 1,000 adults receiving home enteral nutrition (median duration 153 days), shorter survival was predicted by older age, male sex, food-based diets, nasogastric tube use, and multiple comorbidities; longer survival and return to oral feeding were predicted by neurological diagnosis, preserved functional status, and mixed-diet use.
ContextThis descriptive cohort study from Brazil (2006-2015) confirms known associations between patient factors and survival in home enteral nutrition. The findings align with established understanding that older age, comorbidities, and poor functional status predict worse outcomes, while neurological (rather than oncological) diagnoses predict better outcomes in HEN.
No standard claimed for this paper

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.

Association between preoperative malnutrition and hospital length of stay in adults with major lung resection: A prospective cohort study.

Epidemiologymalnutritionhealth servicesepidemiology
Clinical takeawayScreen for preoperative malnutrition in patients scheduled for lung resection to identify those at high risk for prolonged hospitalization and infection. Consider referral for nutritional assessment and targeted interventions; however, evidence that intervention improves postoperative outcomes is not yet established.
What it foundPreoperative malnutrition associated with longer hospital stay (7 vs 4.5 days median) and higher postoperative infection risk (OR 7.0, 95% CI 1.3-36.2) in a prospective cohort of 62 lung resection patients.
ContextMalnutrition is recognized as a risk factor for poor surgical outcomes generally. This prospective study confirms associations in lung resection, though with important population specificity. The unadjusted LOS difference (7 vs 4.5 days) was observed overall; the adjusted analysis (β = 4.2 days) applies specifically to patients undergoing resection for infectious disease, suggesting the strength of benefit may be population-dependent. The postoperative infection risk (OR 7.0) had a wide confidence interval (95% CI 1.3-36.2), limiting the precision of this estimate. Notably, objective measures of nutritional status-fat-free mass index and handgrip strength-did not significantly differ between malnourished and normally nourished groups, suggesting the 7-point SGA may capture clinically relevant nutritional factors not apparent on standard anthropometric assessment.

Decision at stakeidentify and optimize modifiable risk factors before clearing elective major surgery

… Defer elective surgery for active GI bleeding, active IBD flare, recent pancreatitis, or unoptimized anemia, and specify perioperative precautions (stress-dose steroids, biologic hold matrix, GLP-1/SGLT2 holds, aspiration precautions) where indicated.

Our full summary of this standard

Determine GI surgical clearance based on the specific condition and its activity rather than an automatic sign-off: most stable chronic GI conditions (GERD, IBS, controlled IBD, compensated MASLD, asymptomatic gallstones) may be cleared, while active conditions, cirrhosis, and perioperative drug management require explicit stratification and documentation. For any cirrhotic patient, perform mandatory risk stratification with VOCAL-Penn and Child-Pugh class before clearance; manage variceal prophylaxis per individualized endoscopic and hemodynamic assessment (including NSBB for appropriate candidates) and address rebalanced hemostasis without prophylactic INR correction. Defer elective surgery for active GI bleeding, active IBD flare, recent pancreatitis, or unoptimized anemia, and specify perioperative precautions (stress-dose steroids, biologic hold matrix, GLP-1/SGLT2 holds, aspiration precautions) where indicated.
