Abstract
Early evidence-based medical interventions to improve patient outcomes after traumatic brain injury (TBI) are lacking. In patients admitted to the ICU after TBI, optimization of nutrition is an emerging field of interest. Specialized enteral nutrition (EN) formulas that include immunonutrition containing omega-3 polyunsaturated fatty acids (n-3 PUFAs) have been developed and are used for their proposed anti-inflammatory and proimmune properties; however, their use has not been rigorously studied in human TBI populations. A single-center, retrospective, descriptive observational study was conducted at the LAC + USC Medical Center. Patients with severe TBI (sTBI, Glasgow Coma Scale score ≤ 8) who remained in the ICU for ≥2 weeks and received EN were identified between 2017 and 2022 using the institutional trauma registry. Those who received immunonutrition formulas containing n-3 PUFAs were compared with those who received standard, polymeric EN with regard to baseline characteristics, clinical markers of inflammation and immune function, and short-term clinical outcomes. A total of 151 patients with sTBI were analyzed. Those who received immunonutrition with n-3 PUFA supplementation were more likely to be male, younger, Hispanic/Latinx, and have polytrauma needing non-central nervous system surgery. No differences in clinical markers of inflammation or infection rate were found. In multivariate regression analysis, immunonutrition was associated with reduced hospital length of stay (LOS). ICU LOS was also reduced in the subgroup of patients with polytrauma and TBI. This study identifies important differences in patient characteristics and outcomes associated with the EN formula prescribed. Study results can directly inform a prospective pragmatic study of immunonutrition with n-3 PUFA supplementation aimed to confirm the biomechanistic and clinical benefits of the intervention.

Feasibility of Achieving Nutritional Adequacy in Critically Ill Children with Critical Neurological Illnesses (CNIs)?-A Quaternary Hospital Experience. CHILDREN (BASEL, SWITZERLAND) 2024; 11:711. [PMID: 38929290 PMCID: PMC11202205 DOI: 10.3390/children11060711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/04/2024] [Revised: 05/27/2024] [Accepted: 06/06/2024] [Indexed: 06/28/2024]
Abstract
The literature on the nutritional needs and outcomes of critically ill children is scarce, especially on those with critical neurological illnesses (CNIs). Current evidence shows a lower mortality in patients who achieve two-thirds of their nutritional needs during the first week of pediatric intensive care unit (PICU) admission. We hypothesized that achieving 60% of the recommended dietary intake during the first week of a PICU stay is not feasible in patients with CNI. We designed an observational retrospective cohort study where we included all index admissions to the PICU in our institution of children (1 month to 18 years) with CNI from January 2018 to June 2021. We collected patient demographics, anthropometric measures, and caloric and protein intake (enteral and parenteral) information during the first week of PICU admission. Goal adequacy for calories and protein was defined as [(intake/recommended) × 100] ≥ 60%. A total of 1112 patients were included in the nutrition assessment, 12% of whom were underweight (weight for age z score < -2). Of this group, 180 met the criteria for nutrition support evaluation. On the third day of admission, 50% of the patients < 2 years achieved caloric and protein goal adequacy, compared to 25% of patients > 2 years, with p-values of 0.0003 and 0.0004, respectively. Among the underweight patients, 60% achieved both caloric and protein goal adequacy by day 3 vs. 30% of non-underweight patients with p-values of 0.0006 and 0.002, respectively. The results show that achieving 60% of the recommended dietary intake by days 5 and 7 of admission was feasible in more than half of the patients in this cohort. Additionally, children who were evaluated by a clinical dietician during the first 48 h of PICU admission reached higher nutrition adequacy.

Abstract
BACKGROUND Iatrogenic malnutrition is a significant burden to patients, clinicians, and health care systems. Compared with well-nourished patients, underfed patients (those who receive less than 80% of their daily energy requirement) have more adverse outcomes related to nutritional status. Volume-based protocols allow for catch-up titrations, are consistently superior to rate-based protocols, and can be implemented in most settings. LOCAL PROBLEM This project was conducted in an 8-bed neuroscience intensive care unit in which up to 41% of patients who required enteral feeding were underfed. METHODS This quality improvement clinical practice change project used a before-and-after design to evaluate (1) the effect of implementing a volume-based feeding protocol on the delivery of enteral feeds and (2) the effect of a nutrition-based project on staff members' attitudes regarding nutrition in critical care. The effectiveness of a volume-based feeding titration protocol was compared with that of a rate-based feeding protocol for achieving delivery of at least 80% of prescribed nutrition per 24-hour period. Staff members' attitudes were assessed using a survey before and after the project. RESULTS During 241 enteral feeding days (n = 40 patients), the percentage of delivered enteral feeding volume and the percentage of days patients received at least 80% of the prescribed volume increased after volume-based feeding was implemented. After project implementation, 74 staff members reported increased emphasis on nutrition delivery in their practice and a higher level of agreement that nutrition is a priority when caring for critically ill patients. CONCLUSIONS Using a volume-based feeding protocol with supplemental staff education resulted in improved delivery of prescribed enteral feeding.

Abstract
Since the advent of University of Wisconsin preservation solution in the 1980s, clinicians have learned to work within its confines. While affording improved outcomes, considerable limitations still exist and contribute to the large number of livers that go unused each year, often for fear they may never work. The last 10 years have seen the widespread availability of new perfusion modalities which provide an opportunity for assessing organ viability and prolonged organ storage. This review will discuss the role of in situ normothermic regional perfusion for livers donated after circulatory death. It will also describe the different modalities of ex situ perfusion, both normothermic and hypothermic, and discuss how they are thought to work and the opportunities afforded by them.

Nutr Clin Pract 2023; 38:1334-1342. [PMID: 37537901 DOI: 10.1002/ncp.11051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 06/26/2023] [Accepted: 07/09/2023] [Indexed: 08/05/2023] Open
Abstract
BACKGROUND Concomitant administration of enteral nutrition (EN) and phenytoin decreases phenytoin absorption. Concerns over impaired nutrition, however, may prevent EN from being held surrounding phenytoin administration. This study aimed to evaluate whether EN holding guidelines impacted nutrition goal achievement in patients taking phenytoin. METHODS Adult patients administered enteral phenytoin for acute or chronic seizures while receiving EN during a neurocritical care admission 6 months before and after EN holding guideline implementation were eligible. Patients without phenytoin concentrations or a clinical registered dietitian assessment were excluded. The primary outcome was the percentage of nutrition daily goals attained before and after implementation. Secondary end points included the incidence of hypoglycemia, differences in measured phenytoin concentrations, and rates of therapeutic (10-20 mcg/ml) and high-therapeutic (15-20 mcg/ml) concentration attainment. Concentrations were adjusted for hypoalbuminemia using the Winter-Tozer equation. RESULTS Fifty-five patients representing 412 patient days and 1110 phenytoin administrations were included with 29 preimplementation and 26 postimplementation patients. Median percent attainment of daily EN goals was consistent preimplementation and postimplementation (86% vs 83%, P = 0.48). No significant change in rates of days with hypoglycemia was observed. Adjusted phenytoin concentrations were similar before and after implementation (14.1 vs 15.2 mcg/ml, P = 0.45), but the preimplementation cohort had a lower proportion of high-therapeutic concentrations (23% vs 36%, P = 0.018). CONCLUSION Holding EN for phenytoin did not impact attainment of daily nutrition goals and was not associated with increased rates of hypoglycemia. This is the first study to evaluate the effect of EN holding on nutrition goals in patients receiving phenytoin.

Abstract
Emerging science continues to establish the detrimental effects of malnutrition in acute neurological diseases such as traumatic brain injury, stroke, status epilepticus and anoxic brain injury. The primary pathological pathways responsible for secondary brain injury include neuroinflammation, catabolism, immune suppression and metabolic failure, and these are exacerbated by malnutrition. Given this, there is growing interest in novel nutritional interventions to promote neurological recovery after acute brain injury. In this review, we will describe how malnutrition impacts the biomolecular mechanisms of secondary brain injury in acute neurological disorders, and how nutritional status can be optimized in both pediatric and adult populations. We will further highlight emerging therapeutic approaches, including specialized diets that aim to resolve neuroinflammation, immunodeficiency and metabolic crisis, by providing pre-clinical and clinical evidence that their use promotes neurologic recovery. Using nutrition as a targeted treatment is appealing for several reasons that will be discussed. Given the high mortality and both short- and long-term morbidity associated with acute brain injuries, novel translational and clinical approaches are needed.

Abstract
This narrative review aims to shed light on the role of gender differences, on the biological and molecular functions in the main pathological mechanisms that recognize the role of vitamin D. Vitamin D deficiency is widespread worldwide, but it is still very controversial whether the amount of vitamin D taken daily is actually the only problem related to its biological functions. Currently, the plasma concentration of 25-hydroxyvitamin D represents the only indicator of the circulating blood quota. The concept is that the biological function of vitamin D is not only linked to its circulating levels, but it is hypothesized that its biological functions depend, above all, on its total bioavailability. In particular, vitamin D circulates for the most part linked to albumin and vitamin D binding protein (DBP), which depend on various pathological conditions and physiologically, above all, the function of the latter is regulated by estrogens, glucocorticoids, and inflammatory cytokines. During her life, women undergo various changes in the hormonal and sexual sphere concerning menarche, possible pregnancies, and breastfeeding but also the use of contraceptives and, finally, the transition from the period of fertility to menopause. Each of these phases presents specific needs and, consequently, sometimes also specific criticalities. Studies on young women have shown that vitamin D deficiency is present in 58 to 91% of cases. Obesity, metabolic disorders, and variation in estrogen contraction may affect vitamin D deficiency due to the decreased bioavailability from dietary sources due to deposition in body fat compartments.

Abstract
Traditionally, intracranial pressure (ICP) and partial brain tissue oxygenation (PbtO2) have been the primary invasive intracranial measurements used to guide management in patients with severe traumatic brain injury (TBI). After injury however, the brain develops an increased metabolic demand which may require an increment in the oxidative metabolism of glucose. Simultaneously, metabolic, and electrical dysfunction can lead to an inability to meet these demands, even in the absence of ischemia or increased intracranial pressure. Cerebral microdialysis provides the ability to accurately measure local concentrations of various solutes including lactate, pyruvate, glycerol and glucose. Experimental and clinical data demonstrate that such measurements of cellular metabolism can yield critical missing information about a patient's physiologic state and help limit secondary damage. Glucose management in traumatic brain injury is still an unresolved question. As cerebral glucose metabolism may be uncoupled from systemic glucose levels due to the metabolic dysfunction, measurement of cerebral extracellular glucose concentrations could provide more predictive information and prove to be a better biomarker to avoid secondary injury of at-risk brain tissue. Based on data obtained from cerebral microdialysis, specific interventions such as ICP-directed therapy, blood glucose increment, seizure control, and/or brain oxygen optimization can be instituted to minimize or prevent secondary insults. Thus, microdialysis measurements of parenchymal metabolic function provides clinically valuable information that cannot be obtained by other monitoring adjuncts in the standard ICU setting.

Abstract
Neurologic injury often influences various bodily functions associated with digestion. It is imperative for an individual to obtain proper nutrients to maintain a healthy lifestyle and recover from injury. In this review, we explore variables and methods of enteral tube placement in neurologic injury patients influencing recovery, specifically G- and J-tubes. We will first review the patient population by identifying leading causes for enteral tube placement among both pediatric and adult neurologic patients. We will then discuss the general procedures for placement and safety considerations for specified patient populations. We will explore interventions limiting placement of the G- and J-tubes by focusing on two interventions: ventriculoperitoneal shunt (VPS) and intrathecal baclofen (ITB). Then, we will highlight nutritional enhancers that may influence general treatment. Finally, we discuss proper weaning procedures and eJective methods fitting patient needs.

Abstract
Introduction Introduction: subarachnoid hemorrhage (SAH) is a rare and life-threatening cerebrovascular disease. Mitigating the factors that compromise patient recovery during neurocritical care due to SAH is of clinical benefit. Objectives: to evaluate the nutritional risk of patients with aneurysmal subarachnoid hemorrhage using "The Modified Nutrition Risk in the Critically Ill" (mNUTRIC) score, and examine its association with outcomes such as mortality, time of mechanical ventilation, and functional status among survivors. Methods: we designed a cross-sectional study. Patients with SAH admitted to the neurointensive critical care unit (neuroICU) in a tertiary care public hospital were eligible. The inclusion criteria were a minimum stay in the intensive care unit (ICU) of 24 hrs for subarachnoid hemorrhage from a nontraumatic, spontaneously ruptured cerebral aneurysm, and hospital admission within 24 hrs after the onset of symptoms. Results: high nutritional risk as stratified by the mNUTRIC score was associated with discharge type (OR = 0.346; 95 % CI = 0.182-0.650; p = 0.001), acute hypertensive hydrocephalus (OR = 4.371; 95 % CI = 2.283-8.549; p < 0.001), and functional outcome (OR = 0.106; 95 % CI = 0.025-0.0388; p < 0.001). The mNUTRIC score was significantly different among median age (p < 0.001), length of stay in the neuroICU (p = 0.005), SOFA score (p < 0.001), and APACHE II score (p < 0.001) categories. Conclusions: this study demonstrated an association between nutritional risk assessment and outcomes such as length of stay in the neuroICU, type of discharge, functional status, and mortality prediction accuracy.

Abstract
Purpose of Review This article introduces fundamental concepts in circadian biology and the neuroscience of sleep, reviews recent studies characterizing circadian rhythm and sleep disruption among critically ill patients and potentially links to functional outcomes, and draws upon existing literature to propose therapeutic strategies to mitigate those harms. Particular attention is given to patients with critical neurologic conditions and the unique environment of the neuro-intensive care unit. Recent Findings Circadian rhythm disruption is widespread among critically ill patients and sleep time is reduced and abnormally fragmented. There is a strong association between the degree of arousal suppression observed at the bedside and the extent of circadian disruption at the system (e.g., melatonin concentration rhythms) and cellular levels (e.g., core clock gene transcription rhythms). There is a paucity of electrographically normal sleep, and rest-activity rhythms are severely disturbed. Common care interventions such as neurochecks introduce unique disruptions in neurologic patients. There are no pharmacologic interventions proven to normalize circadian rhythms or restore physiologically normal sleep. Instead, interventions are focused on reducing pharmacologic and environmental factors that perpetuate disruption. Summary The intensive care environment introduces numerous potent disruptors to sleep and circadian rhythms. Direct neurologic injury and neuro-monitoring practices likely compound those factors to further derange circadian and sleep functions. In the absence of direct interventions to induce normalized rhythms and sleep, current therapy depends upon normalizing external stimuli.

Abstract
Traumatic brain injury (TBI) is a major cause of long-term physical and psychological disability and death. In patients with TBI, undernutrition is associated with an increased mortality rate, more infectious complications, and worse neurologic outcomes. Therefore, timely and effective nutritional therapy is particularly crucial in the management of TBI to improve patients' prognoses. This narrative review summarizes the issues encountered in clinical practice for patients with neurotrauma who receive acute and post-acute in-patient rehabilitation services, and it comprehensively incorporates a wide range of studies, including recent clinical practice guidelines (CPGs), with the aim of better understanding the current evidence for optimal nutritional therapy focused on TBI patients. Recent CPGs were reviewed for 6 topics: 1) hypermetabolism and variation in energy expenditure in patients with TBI, 2) delayed gastric emptying and intolerance to enteral nutrition, 3) decision-making on the route and timing of access in patients with TBI who are unable to maintain volitional intake (enteral nutrition versus parenteral nutrition), 4) decision-making on the enteral formula (standard or immune-modulating formulas), 5) glycemic control, and 6) protein support. We also identified areas that need further research in the future.
