Outcomes of High-Dose Versus Low-Dose Vitamin D on Prognosis of Sepsis Requiring Mechanical Ventilation: A Randomized Controlled Trial

Background: Critically ill patients with sepsis have a high incidence of vitamin D deficiency. Vitamin D promotes the synthesis of human cathelicidin antimicrobial peptide, a precursor of LL-37, which is a part of the innate immune system. This study investigated the effectiveness and safety of the early administration of high-dose enteral vitamin D3 in comparison with low-dose vitamin D3 in patients with sepsis requiring mechanical ventilation (MV). Methods: Eighty adult patients with sepsis requiring MV with known vitamin D deficiency were randomly assigned to receive either an enteral 50 000 IU (Group I) or 5000 IU (Group II) vitamin D supplementation. Clinical and laboratory parameters were evaluated at baseline and on days 4 and 7 between the study groups. The change in serum procalcitonin (PCT) levels on day 7 was the primary outcome, while the change in serum LL-37 levels on day 7, changes in sequential organ failure assessment (SOFA) score, and clinical pulmonary infection score on day 7, MV duration, and hospital length of stay (LOS) were the secondary outcomes. Results: The (day 7-day 0) change in serum PCT and LL-37 levels and SOFA score were significantly different in Group I (P = .010, P < .001, and P < .001, respectively). The SOFA score was significantly different on days 4 and 7 in Group I (P < .001 and P < .001, respectively). The incidence of early ventilator-associated pneumonia was significantly different between both treatment groups (P = .025). The hospital LOS was shorter in Group I (P < .001). No 25-hydroxyvitamin-D toxicity was observed in either group. Conclusions: Early enteral administration of high-dose vitamin D3 in critically ill patients with sepsis requiring MV along with standard treatment for sepsis decreased serum procalcitonin levels, increased serum LL-37 levels, and ameliorated illness severity scores.

Oral Glyburide for the Prevention of Cerebral Edema in Acute Ischemic Stroke

OBJECTIVE

The purpose of this study was to describe the impact of enteral glyburide on cerebral edema formation and hypoglycemia when used in patients diagnosed with acute ischemic stroke (AIS).

METHODS

This study was a single-center, retrospective chart review that included all patients at least 18 years of age diagnosed with AIS who received at least one dose of enteral glyburide for the prevention of cerebral edema from January 1st, 2018 to March 31st, 2022. The primary outcome was to describe the percentage of patients requiring intervention for cerebral edema management following glyburide initiation, and the safety outcome was to describe the occurrence of hypoglycemia in this patient population.

RESULTS

The final evaluation included 44 patients, with 6 (14%) patients requiring intervention for cerebral edema after glyburide initiation. Average baseline NIHSS was 19. Overall, in-hospital mortality was 17 (36%), and hypoglycemia occurred in 7 (15%) patients. Twenty (45%) patients received a partial duration of enteral glyburide (1-4 doses) and 24 (55%) patients received a full duration of enteral glyburide (5-7 doses). There was a lower rate of intervention for cerebral edema (10% vs 17%) and hypoglycemia (5% vs 23%) in the partial duration versus the full duration group, respectively. In-hospital all-cause mortality rate was higher in the partial duration versus the full duration group (43% vs 31%).

CONCLUSIONS

Despite relatively low rates of intervention for cerebral edema, hypoglycemia was common, particularly in patients receiving 5-7 doses of enteral glyburide for the prevention of cerebral edema in patients with moderate-to-severe AIS.

Enteral administration of crushed rilpivirine in a patient with HIV: A case report

Antiretroviral therapy administration is challenging in patients with HIV requiring enteral nutrition. There are limited pharmacokinetic data available regarding the absorption of crushed rilpivirine (RPV) and its impact on drug bioavailability, plasma concentrations and, consequently, the efficacy of treatment. We present the case of a 60-year-old woman with HIV diagnosed with squamous cell carcinoma who needed enteral administration of antiretroviral therapy following the insertion of a gastrotomy tube in September 2018. Initially, the patient was treated with a daily dose of RPV 25 mg, dolutegravir 50 mg and emtricitabine 200 mg. The treatment was later intensified with darunavir boosted with ritonavir. RPV and dolutegravir were crushed, dissolved in water and administered via a percutaneous endoscopic gastrostomy tube. Therapeutic drug and viral load monitoring determined the adequacy of enteral antiretroviral dosing. RPV plasma concentrations remained within the expected therapeutic range of 43-117 ng/mL, with only 1 below the currently used 50 ng/mL efficacy threshold. After the treatment intensification with darunavir boosted with ritonavir, the patient achieved an undetectable viral load. While we observed satisfactory RPV plasma concentrations, it is essential to maintain strict monitoring of administration method, plasma concentrations and virological responses when initiating treatment with crushed RPV. Hence, additional pharmacokinetic data are necessary to ensure the effective enteral administration of RPV and to establish the best antiretroviral dosing regimens.

Proportion of unplanned tube replacements and complications following gastrostomy: A systematic review and meta-analysis

AIMS

Gastrostomy feeding represents a vital component of supportive care provided to people with swallowing or feeding difficulties; however, the rate of specific long-term complications is currently unknown in the adult population. This study aimed to determine the prevalence of specific long-term gastrostomy-related complications and unplanned replacements in adults.

METHODS

A prospective systematic review of Medline, CINAHL and Embase databases was performed. Key complications of hypergranulation, infection and displacement among studies relevant to percutaneous endoscopic gastrostomy tubes, radiologically inserted gastrostomy tubes and balloon replacement tubes were critically appraised by two independent reviewers. Results were synthesised quantitatively in a meta-analysis using random effects where the population and condition were sufficiently homogeneous.

RESULTS

In total, 453 studies were identified, of which 17 met inclusion criteria. 8.5% of adults with a gastrostomy were found to have had an infection ≥42 days after initial tube insertion (p < 0.01), while 13% had hypergranulation (p < 0.01). Displacement occurred in 10.8% of adults (p < 0.01), with age (p < 0.001) and sex (p < 0.001) presenting as a risk factor (R2  = 75%) following meta-regression.

CONCLUSIONS

Approximately 1 in 10 people with a gastrostomy will experience a complication related to either hypergranulation, infection or dislodgement. Age, in combination with sex, may provide a guide for risk of displacement among adult female cohorts, though further studies reporting prevalence of gastrostomy-related complications along with participant demographics are required.

Safety of the One Step Percutaneous Endoscopic Gastrostomy (Push-PEG) Button in Pediatric Patients

OBJECTIVES

Percutaneous endoscopic gastrostomy (PEG)-systems are essential tools for enteral feeding in a broad variety of pediatric patients. The One Step ("Push-PEG") technique allows the direct introduction of a PEG-Button. The aim of the study was to investigate the safety and parental view of the Push-PEG technique.

METHODS

We conducted a single-center retrospective data and questionnaire (SDC, http://links.lww.com/MPG/D296 ) based study including all pediatric patients receiving a PEG via push or pull technique between 2015 until end of 2020 and compared these 2 groups. The primary outcome was the detection of minor and major complications. Secondary outcomes were growth, thriving, and parental contentment using a Likert-scaled questionnaire.

RESULTS

Eighty-three patients were included in the analysis. There were no significant differences in the basic data regarding age, weight, or diagnosis category. Overall complication rate was 34.9%. The Push-PEG group showed a lower rate of complications (32.7% vs 38.7%) and a lower rate of major complications (4.1% vs 8.8%), although the difference is not significant. Thirty-four families completed the questionnaire (SDC, http://links.lww.com/MPG/D296 ) (response rate 40%). There were no significant differences between the 2 groups regarding answers of the Likert-scaled questions.

CONCLUSION

Push-PEG placement seems to be as safe as placement via traditional pull technique, even in small infants more than 2.8 months and 4 kg. As Push-PEG placement requires less follow-up interventions it may show significant advantages and could be the method of first choice in many cases.

Medical line entanglement: The unspoken patient safety hazard of medical devices

BACKGROUND

In February 2022, the US Food and Drug Administration published a safety communication regarding the risk of strangulation from enteral feeding delivery sets. When it comes to the causes of accidental strangulation or asphyxiation, it is common knowledge that household items, such as window blind cords, are potential hazards. However, many people may not expect that medical devices may pose similar risks because of medical line entanglement (MLE).

METHODS

A survey of clinicians from pediatric acute care and outpatient facilities and caregivers of patients with medical lines was conducted with a goal to understand if clinicians and caregivers are aware of MLE, if healthcare facilities have policies and procedures related to the prevention of MLE, and if education about the risks of MLE is provided to caregivers when they first receive a medical device.

RESULTS

The survey was shared through clinician organizations and patient advocacy groups. Responses were received from 191 clinicians and 117 caregivers. A majority of clinicians reported awareness of the risk of entanglement; however, few received direction from their employer on managing these risks. Caregivers (N = 106) reported that their child had experienced MLE, however only 9% of those caregivers recalled receiving any education on MLE from their healthcare providers.

CONCLUSION

This survey demonstrates the need for healthcare facilities to develop programs for managing risks of MLE and for healthcare teams and caregivers to discuss prevention methods whenever an at-risk patient is sent home with a medical device that poses a risk for entanglement.

The efficacy of different nimodipine administration route for treating subarachnoid hemorrhage: A network meta-analysis

BACKGROUND

A systematic review and network meta-analysis (NMA) were conducted to explore the optimal administration route of nimodipine for treatment subarachnoid hemorrhage.

METHODS

Electronic databases (Pubmed, Embase, Web of Science and Cochrane databases) were systematically searched to identify randomized controlled trials evaluating different administration route of nimodipine (intravenous and enteral) versus placebo for treatment subarachnoid hemorrhage. Outcomes included case fatality at 3 months, poor outcome measured at 3 months (defined as death, vegetative state, or severe disability), incidence of delayed cerebral ischemia (DCI), delayed ischemic neurological deficit. A random-effect Bayesian NMA was conducted for outcomes of interest, and results were presented as odds ratios (ORs) and 95% credible intervals. The NMA was performed using R Software with a GeMTC package. A Bayesian NMA was performed and relative ranking of agents was assessed using surface under the cumulative ranking (SUCRA) probabilities.

RESULTS

Nine randomized controlled trials met criteria for inclusion and finally included in this NMA. There was no statistically significant between intravenous and enteral in terms of case fatality, the occurrence of DCI, delayed ischemic neurologic deficit and poor outcomes (P > .05). Both intravenous and enteral could reduce case fatality, the occurrence of DCI, delayed ischemic neurologic deficit and poor outcomes (P < .05). The SUCRA shows that enteral ranked first, intravenous ranked second and placebo ranked the last for case fatality, the occurrence of DCI and poor outcomes. The SUCRA shows that intravenous ranked first, enteral ranked second and placebo ranked the last for delayed ischemic neurologic deficit.

CONCLUSIONS

It is possible that both enteral and intravenous nimodipine have comparable effectiveness in preventing poor outcomes, DCI, and delayed ischemic neurological deficits. However, further investigation may be necessary to determine the exact role of intravenous nimodipine in current clinical practice.

The Impact of Estimated Energy and Protein Balances on Extrauterine Growth in Preterm Infants

BACKGROUND

Nutritional support of preterm infants remains a field of debate in the literature and clinical practice varies significantly. Adequate nutrition should promote growth and aim for optimal later neurodevelopment. However, it is often impaired by prematurity-associated morbidity and the physiologic immaturity of preterm infants. This study assessed the impact of energy and macronutrient provision on growth velocity and outcome and explored differences attributed to the heterogeneity of the preterm population.

METHODS

We retrospectively collected clinical and nutritional data from neonates hospitalized in two separate Neonatal Intensive Care Units (NICUs). Estimated energy and protein balance were calculated based on the ESPGHAN guidelines and their association with the growth outcome was explored. Growth assessment was based on somatometry Delta (Δ) z-scores at discharge.

RESULTS

In total, 174 neonates were included in the study. By day 14, most preterm infants were exclusively enterally fed, whereas there were infants in the <28 and 28-31+6 subgroups fed exclusively parenterally. Energy balance was positive for all gestational age (GA) subgroups except for those born <28 weeks. Protein balance was consistently positive for extremely premature but negative for late preterms. Cumulative substrates provisions were strong predictors of a positive energy or protein balance in the <34 weeks GA preterms on days 14 (ROC analyses, p < 0.001) and 7 (p < 0.05). A higher GA (p = 0.013) and enteral nutrition (p = 0.005) were additional predictors of a positive energy balance. All GA subgroups had a negative Δ z-score of weight at discharge. In the <34 GA subcohorts, a positive protein balance on day 14 (p = 0.009) and a short time to regain birth weight (exp(B) 3.1 (p = 0.004)) were independently associated with a positive Δ z-score of weight at discharge.

CONCLUSIONS

Early achievement of a positive energy and protein balance, based on the ESPGHAN guidelines, is crucial to ensure optimal postnatal growth and prevent extrauterine growth restriction, a relatively common occurrence in preterm infants.

Pediatric formulas: Categories, composition, and considerations

Formulas, liquid nutrition, may be consumed orally or via a feeding tube to provide partial or complete nutrition that a given individual could not obtain using natural food stuffs in their native form. A wide range of commercially available formulas exist, which may be used as sole-source nutrition or in conjunction with other foods. Physicians and dietitians must understand the nature of and indications for specific formulas to treat diseases, provide complete nutrition to patients, and avoid harm. Products vary in macronutrient and micronutrient content and calorie concentration among many other factors. They are formulated specifically for patients of specific ages, correlating to nutritional needs and medical diagnoses. Additionally, formula availability, insurance coverage, mode of consumption, physiologic tolerance, and caregiver preference influence formula selection. Caregivers may also make their own pediatric formulas. We review commercial and homemade pediatric formulas.

Home Enteral Nutrition: A Descriptive Study

BACKGROUND

With data demonstrating benefit, the prevalence of Home Enteral Nutrition (HEN) has increased significantly over the last few decades. Despite this increase, there remains a paucity of data regarding real-world use of HEN including clinical outcomes and complications.

METHODS

Descriptive analysis of the prospectively maintained database of our specialized HEN program was undertaken. Patients who received care in our program with HEN initiation date between January 1st, 2018, and December 31st, 2020, were included in the analysis. Data regarding demographic information, anthropometrics, EN regimen, electrolytes, and nutrition therapy history were included and tracked until July 31st, 2021.

RESULTS

During the study period, 1600 patients were initiated on HEN under our care. Majority of study population needed EN therapy due to malignancy and its complications including malignant dysphagia or mechanical obstruction (60.6%) followed by neuro-degenerative diseases (7.5%). By the end of study period, majority of patients (82%) had their HEN stopped. Of these, close to half (44.2%) achieved EN goals and/or oral autonomy. Patients stayed on HEN for median of 100 (IQR 32-301) days. Overall, 53.2% of patients experienced/reported at least one HEN related complication that was addressed and clinically managed by the HEN team. Complications included tube-related, enteral feeding intolerance (EFI), and electrolyte shifts.

CONCLUSION

In our study population, HEN was most utilized to manage malignancy related complications including dysphagia. Unfortunately, complications including EFI and tube related complications remained quite prevalent. Further evaluation regarding risk factors for complications and preventive mechanisms such as increased education is indicated. This article is protected by copyright. All rights reserved.

A randomized, open-label, two-treatment crossover study to evaluate the effect of food on the pharmacokinetics of diazepam nasal spray in healthy adults

OBJECTIVE

The pharmacokinetics of oral diazepam are affected by food, but food-effect studies have not been conducted for diazepam nasal spray because it is believed that most absorption occurs via the nasal mucosa. However, gastrointestinal side effects reported with nasal diazepam suggest that at least a portion of the drug may be absorbed enterally and thus subject to food effects. The objective of this study was to evaluate the possible effects of food on the pharmacokinetics of diazepam nasal spray in healthy adults.

METHODS

This randomized, open-label crossover study compared equal doses of diazepam nasal spray after an overnight fast and after a standardized high-fat, high-calorie breakfast. Each participant served as their own control, and there was a washout period of at least 21 days between treatments.

RESULTS

Twenty-four healthy adults enrolled in this study. Two participants withdrew consent, and two had pre-dose diazepam concentrations that exceeded the protocol-defined minimum after the washout period and were excluded from the final analysis population of 20 participants. Under fed conditions, the mean maximum plasma diazepam concentration was decreased by 48% (p < .0001) and the overall diazepam exposure during the first 4 h was reduced by 57% (p < .0001) compared with fasted conditions. The time to maximum plasma concentration was 4.0 h in the fed state compared with 2.0 h in the fasted state (p < .0001). At 2 h post-dose, diazepam concentrations were ≥150 ng/mL for 100% of the participants when in the fasted state and 30% when in the fed state. Significantly more participants experienced adverse events under fasted conditions (83.3%) than under fed conditions (54.5%; p = .0340).

SIGNIFICANCE

This study in healthy volunteers demonstrated that food significantly decreases and delays the absorption of diazepam dosed via nasal spray. Patients using diazepam nasal spray after eating may obtain diazepam concentrations that are below those needed for seizure control.

The diagnostic accuracy of ultrasonography over manual aspiration for gastric reserve volume estimation in critically ill patients

BACKGROUND

Although gastric reserve volume (GRV) is a surrogate marker of gastrointestinal dysfunction and feeding intolerance, there is ambiguity in its estimation due to problems associated with its measurement. Introduction of point-of-care ultrasound as a tool for anesthetists kindled interest in its use for GRV estimation.

METHODS

In this prospective observational study, we recruited 57 critically ill patients and analyzed 586 samples of GRV obtained by both ultrasonography (USG) and manual aspiration.

RESULTS

The analysis showed that USG-guided GRV was significantly correlated (r=0.788, P<0.001) and in positive agreement with manual aspiration based on Bland-Altman plot, with a mean difference of 8.50±14.84 (95% confidence interval, 7.389-9.798). The upper and lower limits of agreement were 37.7 and -20.5, respectively, within the ±1.96 standard deviation (P<0.001). The respective sensitivity and positive predictive value, specificity and negative predictive value, and area under the curve of USG for feeding intolerance were 66.67%, 98.15%, and 0.82%, with 96.49% diagnostic accuracy.

CONCLUSIONS

Ultrasonographic estimation of GRV was positively, significantly correlated and in agreement with the manual aspiration method and estimated feeding intolerance earlier. Routine use of gastric USG could avoid clinical situations where feeding status is unclear and there is high risk of aspiration and could become a standard practice of critical care.

Postnatal Leptin Levels Correlate with Breast Milk Leptin Content in Infants Born before 32 Weeks Gestation

Perinatal leptin deficiency and reduced intake of mother’s milk may contribute to the development of childhood obesity. Preterm infants have reduced leptin production, and they are at heightened risk of neonatal leptin deficiency. Because fresh human milk contains significantly more leptin than donor milk, we used a cross-over design to determine if blood leptin levels in maternal milk-fed preterm infants fall during conversion to donor human milk. Infants born between 22 0/7 and 31 6/7 weeks gestation on exclusive maternal milk feedings were enrolled into a 21-day cross-over trial. On days 1−7 and 15−21, infants were fed maternal milk, and on days 8−14, infants were fed donor milk. On day 1, study infants had a mean postmenstrual age of 33 weeks. Plasma leptin correlated with milk leptin, and leptin levels in maternal milk far exceed the leptin levels of donor milk. Plasma leptin did not increase during donor milk administration, but it did following resumption of maternal milk (p < 0.05). In this crossover trial, preterm infant blood leptin levels correlated with milk leptin content. This suggests that preterm infants can enterally absorb leptin from human milk, and leptin-rich breast milk may be a targeted therapy for the prevention of obesity.

Placement of Nasogastric Feeding Tube and Postinsertion Care Review

Insertion and postinsertion care of enteral nasogastric feeding tubes are common procedures in the United States, with more than 1.2 million temporary nasogastric feeding tubes inserted annually. Although there are some evidence-based practice guidelines and recommendations for care of these tubes, variation in practice still exists. Additional research is needed to determine the best methodology for insertion and confirmation of nasogastric feeding tubes. Routine competency and training on feeding tube insertion, enteral nutrition, and postinsertion care is crucial to prevent patient safety events. Variable results have been reported with different technologies; however, radiographic confirmation remains the criterion standard. It is important that health care institutions develop standardized procedures for insertion and confirmation on the basis of evidence-based practices to minimize risks and complications from temporary nasogastric feeding tubes.

Alternate dosage formulations of oral targeted anticancer agents

OBJECTIVE

Oral anticancer therapies have demonstrated superior outcomes compared to traditional cytotoxic chemotherapy in many disease states. However, certain patients may not be candidates for these agents due to odynphagia or dysphagia. The purpose of this review is to summarize the data for extemporaneous compounding of oral anticancer agents.

DATA SOURCES

Food and drug administration approvals of oncology agents were reviewed to identify oral anticancer therapies. In order to find alternative administration options: the package inserts of each of these agents were reviewed, each medication was searched in a tertiary drug information resource, the medical information teams of each drug manufacturer were contacted to inquire about proprietary data, sites with pediatric trials were contacted, a primary literature search was performed, and listservs for national pharmacy and oncology organizations were reviewed.

DATA SUMMARY

Eighty-five food and drug administration-approved oral anticancer therapies were identified to be included. Of those agents, nine (11%), had information in the package insert related to alternative administration. After further research, 46 (54%) of the agents had some information related to alternate formulations for administration. The recipes and stability of each of these compounds is included.

CONCLUSIONS

The majority of agents do not have Phase I or II trials that assess safety or pharmacokinetics of alternative formulations. Clinicians should exercise caution when recommending or administering these agents outside of food and drug administration-approved indicated use and utilize clinical judgment in assessing the risks and benefits of altering anticancer compounds. However, the alternative administration considerations presented can increase access to oncology patients who have difficulty swallowing.

Academy of Nutrition and Dietetics and American Society for Parenteral and Enteral Nutrition: Revised 2021 standards of practice and standards of professional performance for registered dietitian nutritionists (competent, proficient, and expert) in nutrition support

Nutrition support is a therapy that crosses all ages, diseases, and conditions as health care practitioners strive to meet the nutrition requirements of individuals who are unable to meet nutrition and/or hydration needs with oral intake alone. Registered dietitian nutritionists (RDNs), as integral members of the nutrition support team provide needed information, such as identification of malnutrition risk, macro- and micronutrient requirements, and type of nutrition support therapy (eg, enteral or parenteral), including the route (eg, nasogastric vs nasojejunal or tunneled catheter vs port). The Dietitians in Nutrition Support Dietetic Practice Group, American Society for Parenteral and Enteral Nutrition, along with the Academy of Nutrition and Dietetics Quality Management Committee, have updated the Standards of Practice (SOP) and Standards of Professional Performance (SOPP) for RDNs working in nutrition support. The SOP and SOPP for RDNs in Nutrition Support provide indicators that describe the following 3 levels of practice: competent, proficient, and expert. The SOP uses the Nutrition Care Process and clinical workflow elements for delivering patient/client care. The SOPP describes the 6 domains that focus on professional performance. Specific indicators outlined in the SOP and SOPP depict how these standards apply to practice. The SOP and SOPP are complementary resources for RDNs and are intended to be used as a self-evaluation tool for assuring competent practice in nutrition support and for determining potential education and training needs for advancement to a higher practice level in a variety of settings.

Early Enteral Feeding in Preterm Infants: A Narrative Review of the Nutritional, Metabolic, and Developmental Benefits

Enteral feeding is the preferred method of nutrient provision for preterm infants. Though parenteral nutrition remains an alternative to provide critical nutrition after preterm delivery, the literature suggests that enteral feeding still confers significant nutritional and non-nutritional benefits. Therefore, the purpose of this narrative review is to summarize health and clinical benefits of early enteral feeding within the first month of life in preterm infants. Likewise, this review also proposes methods to improve enteral delivery in clinical care, including a proposal for decision-making of initiation and advancement of enteral feeding. An extensive literature review assessed enteral studies in preterm infants with subsequent outcomes. The findings support the early initiation and advancement of enteral feeding impact preterm infant health by enhancing micronutrient delivery, promoting intestinal development and maturation, stimulating microbiome development, reducing inflammation, and enhancing brain growth and neurodevelopment. Clinicians must consider these short- and long-term implications when caring for preterm infants.

Transition to Peptide-Based Diet Improved Enteral Nutrition Tolerance and Decreased Healthcare Utilization in Pediatric Home Enteral Nutrition

Background

Home enteral nutrition (HEN) use continues to increase in children unable to meet nutritional needs through oral intake. Some patients do not tolerate standard polymeric formula (SPF), which may lead to malnutrition. Use of peptide‐based diet (PBD) has demonstrated benefits in adults, however there remains a paucity of data in pediatric population.

Methods

Retrospective review of medical records of children receiving HEN between October 2015 and October 2019 was conducted. Nutrition, tolerance, and healthcare utilization was tracked through May 2020. Children receiving PBD as initial formula or transitioned to PBD from SPF were included. Our objective was to assess gastrointestinal tolerance and impact on healthcare utilization in children receiving PBD.

Results

During study period, 30 children (mean age, 9 ± 5.44 years; 20 of 30 [66.7%] male) utilized PBDs. Twenty‐one patients started PBD directly with malnutrition as primary indication. Nine patients transitioned from SPF to PBD, most often due to intolerance of SPF (66%). After transition to PBD, no symptoms were reported in 6 of 9 (66.7%) patients, and symptoms of SPF intolerance resolved in 4 of 9 (44.5%) patients. Healthcare utilization declined significantly after transition to PBD, including mean numbers of emergency room visits (0.78 ± 1.09 to 0.11 ± 0.33; P = .025), provider visits (1.67 ± 1.32 to 0.56 ± 0.73; P = .007), and phone calls (1.22 ± 1.39 to 0.33 ± 0.50; P = .026).

Conclusions

PBD is well tolerated and can result in significant reduction in healthcare utilization in children intolerant to SPF.

A case study demonstrating tolerance of the gut to large volumes of enteral fluids as a complement to IV fluid resuscitation in burn shock

Appropriate intravenous fluid resuscitation has improved early post burn outcomes. However, clinical and pre-clinical evidence suggests that enteral or oral resuscitation may complement intravenous fluid administration. While this strategy is often discussed in the context of resource-limited settings, its implementation could reduce overall IV fluid requirements and simplify management during routine care. Conversely, concerns about this strategy have been raised over impaired gut perfusion and function leading to adverse effects. We present a case of an 82-year-old man with a total burn size of 14% who was encouraged to ingest the oral rehydration solution Drip Drop® starting 7 hours post-burn. In the ensuing 17 hours he consumed over 5 L of oral rehydration solution, which was nearly 1 L more than the total amount of IV fluids he received. There were no adverse gastrointestinal side effects. This demonstrates tolerance of a significant volume of voluntary oral fluids in combination with IV resuscitation. Clinical trials are warranted.

Methadone bioavailability and dose conversion implications with intravenous and enteral administration: A scoping review

PURPOSE

Despite its availability for more than 70 years, many details concerning methadone remain contentious, such as the dosing equivalents for intravenous and enteral administration. A scoping review was performed to evaluate whether existing literature on methadone bioavailability in human subjects support the current recommendation that an equivalent enteral dose is twice the intravenous dose.

METHODS

A librarian-assisted search of the PubMed and EMBASE databases identified all English-language articles with the terms methadone and bioavailability and/or conversion in the title or abstract published from inception though December 2019. A manual search of references was also performed to identify any additional articles. Studies were included in a scoping review if they were published in English and evaluated methadone bioavailability in human subjects.

RESULTS

Among 65 publications initially identified, 6 studies involving a total of 50 patients were included in the review. Bioavailability data for healthy volunteers and patients with opioid use disorder, metastatic cancer, chronic pain from malignant or nonmalignant disease were available for analysis. The pooled mean (95% confidence interval) bioavailability (F) was 85.4% (75.2%-95.6%), with heterogeneity (I2) of 0. In the 4 studies that provided individual patient-level data, F was >50% in 40 of 42 patient measurements (95.2%) and ≥75% in 33 of 42 patient measurements (78.6%).

CONCLUSION

Available evidence suggests the bioavailability of methadone is generally more than 75%, there is limited evidence for the currently recommended 1:2 ratio (intravenous:enteral), and a more appropriate dosing ratio may be 1:1.3. This scoping review underscores the need for further research to establish an effective and safe ratio when converting between intravenous and enteral dosing formulations of methadone.

Single-center analysis of the inappropriate use of human albumin and nutritional support in hospitalized patients with hypoproteinemia in China

BACKGROUND

This study used single-center analysis of human serum albumin clinical usage and enteral-parenteral nutritional support to establish clinical application standards for the rational use of human serum albumin.

METHODS

A total of 1984 patients receiving human serum albumin were enrolled in this retrospective study to analyze the rational application of human serum albumin and enteral-parenteral nutritional support.

RESULTS

Among 1984 patients, 1044 (52.6%) were found to have irrational applications for human serum albumin use. Major indications for irrational applications were hypoproteinemia (30.0%) and nutritional support (21.9%). Surgical departments including thoracic surgery, orthopedics, and neurosurgery had the most irrational applications, occupying 18.4%, 8.4%, and 4.2%, respectively. A total of 1627 patients (82%) required nutritional support and 745 (45.8%) had irrational nutritional support. Moreover, 694 patients (35.0%) received human serum albumin as the only source of nutritional support.

CONCLUSIONS

Clinical training and the establishment of an approval system should be used to enhance the rational use of human serum albumin, ensuring medication safety, reducing medical costs, and avoiding the waste of medical resources.

Enteral and parenteral nutrition considerations in pediatric patients

PURPOSE

Current clinical practice guidelines on management of enteral nutrition (EN) and parenteral nutrition (PN) in pediatric patients are reviewed.

SUMMARY

The provision of EN and PN in pediatric patients poses many unique considerations and challenges. Although indications for use of EN and PN are similar in adult and pediatric populations, recommended EN and PN practices differ for pediatric versus adult patients in areas such as selection of EN and PN formulations, timing of EN and PN initiation, advancement of nutrition support, and EN and PN goals. Additionally, provision of EN and PN to pediatric patients poses unique compounding and medication administration challenges. This article provides a review of current EN and PN best practices and special nutrition considerations for neonates, infants, and other pediatric patients.

CONCLUSION

The provision of EN and PN to pediatric patients presents many unique challenges. It is important for pharmacists to keep current with pediatric- and neonatal-specific guidelines on nutritional management of various disease states, as well as strategies to address compounding and medication administration challenges, in order to optimize EN and PN outcomes.

Continuous Feedings Are Not Associated With Lower Rates of Gastroesophageal Reflux When Compared With Bolus Feedings

Gastroesophageal reflux disease is common in children with gastrostomy tubes. Clinicians often transition to continuous feedings in an attempt to reduce reflux burden, though there is limited data to support this practice. In this retrospective study, we analyzed 24-hour multichannel intraluminal impedance with pH studies in 18 children with gastrostomy tubes receiving exclusive enteral nutrition with a combination of daytime bolus and overnight continuous feedings. There were no significant differences in the rate of reflux (reflux events per hour) between no feeding, bolus feeding, and continuous feeding periods overall or stratified by prior fundoplications (P > 0.40). After adjusting for age, BMI, feeding rate, and feeding volume in multivariate analysis, there were no significant differences in the risk of reflux between different feeding periods. These results suggest that continuous feedings may not offer a significant advantage in reducing reflux burden.

Enteral feeding is associated with longer survival in the advanced stages of prion disease

To report the frequency, complications, survival and motivations for enteral feeding in UK patients with prion diseases. We analysed data from an ongoing prospective observational cohort study of UK patients with prion diseases (n = 635). Gastrostomy-treated cases were matched by age, gender, disease aetiology, severity, duration and a genetic predictor of survival (ratio 1:3.1). The main outcome was survival (unadjusted log-rank test); secondary outcomes were future functional impairments, complications and retrospective carer interviews to determine qualitative benefits and motivations. Enteral feeding is uncommon in UK patients with prion diseases (n = 26/635; 4.1%), but more frequent in acquired (7/41, 17.1%) and inherited (7/128, 5.5%) compared with sporadic disease (12/466, 2.6%; P = 3 × 10⁻⁵ chi-squared), and used mostly at advanced stages. Enteral feeding was complicated by infection and the need for reinsertions, but associated with markedly longer survival at advanced neurodisability (median 287 days, range 41–3877 versus 17 days, range 0–2356; log-rank test in three aetiologies each P < 0.01). Interviews revealed different motivations for enteral feeding, including perceived quality of life benefits. We provide Class II evidence that enteral feeding prolongs the akinetic-mute phase of all aetiological types of prion disease. These data may help support decision making in palliative care. Enteral feeding is an important potential confounder in prion disease clinical trials that use survival as an endpoint.

Continuous fluid infusion per rectum compared with intravenous and nasogastric fluid administration in horses

BACKGROUND

Rectal fluid administration may offer a simple, safe and inexpensive alternative to intravenous or nasogastric fluid therapy in equine clinical cases.

OBJECTIVES

To evaluate the tolerance and effects of rectally administered fluid and compare the measurements of haemodilution and intravascular volume with those during nasogastric and intravenous fluid administration.

STUDY DESIGN

Randomised controlled experimental trial.

METHODS

Six clinically normal Standardbred geldings were used in a 4-way crossover study: each received three different fluid treatments (intravenous, nasogastric and rectal) at 5 mL/kg/h for 6 h and underwent a control (no treatment) with water and feed withheld. Bodyweight was measured at baseline and 6 h. Packed cell volume (PCV), total solids (TS), albumin, electrolytes, lactate, urine specific gravity, vital parameters, gastrointestinal borborygmi and central venous pressure were measured every 2 h.

RESULTS

Rectal fluid administration with plain water was well tolerated and caused clinical chemistry changes consistent with haemodilution, indicating absorption. Mean (95% confidence interval) PCV decreased from 40% [40-42] at 0 h to 35% [34-36] at 6 h during rectal fluid treatment (P<0.001), similar to decreases in PCV occurring also with i.v. and nasogastric (NGT) treatment (P<0.001). The TS also decreased with i.v. and rectal fluid (P<0.001). There was a decrease in bodyweight in the control (P<0.001) but not with any of the fluid treatments.

MAIN LIMITATIONS

A small sample size of healthy, euhydrated horses and a relatively short duration of fluid administration was used.

CONCLUSIONS

Rectal fluid administration requires clinical evaluation, but may offer an inexpensive, safe alternative or adjunct to i.v. fluid administration, particularly when administration via NGT is not possible or contraindicated. The Summary is available in Portuguese - see Supporting Information.

Optimizing Enteral Nutrition for Growth in Pediatric Chronic Kidney Disease (CKD)

Growth in pediatric Chronic Kidney Disease is important for long-term outcomes including final adult height and cognitive function. However, there are many barriers for children with chronic kidney disease to achieve adequate nutritional intake to optimize growth. This review highlights these unique concerns, including route of nutrition, dialysis contributions and biochemical indices. Fitting the enteral feeding to the patients' needs involves choosing an appropriate product or products, limiting harmful nutrients in excess, notably aluminum, and altering for electrolyte and micronutrient needs. Unique adjustments to the enteral regimen include accommodating volume needs, optimizing macronutrient ratios, specific electrolyte adjustments, the blending of products together, and adjustments made to consider patient and family psychosocial needs. When a holistic approach to medical nutrition therapy is applied, taking the above factors into consideration, adequate intake for growth of the child with CKD is achievable.

Nutritional management of the foal with diarrhoea

Diarrhoea is a common problem in the neonatal and suckling foal. In certain circumstances supplemental nutrition is necessary depending on the age of foal, severity of diarrhoea and presence of other systemic manifestations. Nutritional supplementation can be provided either enterally or parenterally. Enteral nutrition is superior to parenteral nutrition because it is the most natural and physiologically sound means to provide nutritional support. Parenteral nutrition may be warranted if the foal is unable to receive or tolerate enteral nutrition. Dextrose alone or with amino acids and lipids can provide appropriate nutrition when enteral feeding is not tolerated. As soon as the foal stabilises enteral feeding can be reintroduced.

Management of Acute Pancreatitis in the Pediatric Population: A Clinical Report From the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition Pancreas Committee

BACKGROUND

Although the incidence of acute pancreatitis (AP) in children is increasing, management recommendations rely on adult published guidelines. Pediatric-specific recommendations are needed.

METHODS

The North American Society for Pediatric Gastroenterology, Hepatology and Nutrition Pancreas committee performed a MEDLINE review using several preselected key terms relating to management considerations in adult and pediatric AP. The literature was summarized, quality of evidence reviewed, and statements of recommendations developed. The authorship met to discuss the evidence, statements, and voted on recommendations. A consensus of at least 75% was required to approve a recommendation.

RESULTS

The diagnosis of pediatric AP should follow the published INternational Study Group of Pediatric Pancreatitis: In Search for a CuRE definitions (by meeting at least 2 out of 3 criteria: (1) abdominal pain compatible with AP, (2) serum amylase and/or lipase values ≥3 times upper limits of normal, (3) imaging findings consistent with AP). Adequate fluid resuscitation with crystalloid appears key especially within the first 24 hours. Analgesia may include opioid medications when opioid-sparing measures are inadequate. Pulmonary, cardiovascular, and renal status should be closely monitored particularly within the first 48 hours. Enteral nutrition should be started as early as tolerated, whether through oral, gastric, or jejunal route. Little evidence supports the use of prophylactic antibiotics, antioxidants, probiotics, and protease inhibitors. Esophago-gastro-duodenoscopy, endoscopic retrograde cholangiopancreatography, and endoscopic ultrasonography have limited roles in diagnosis and management. Children should be carefully followed for development of early or late complications and recurrent attacks of AP.

CONCLUSIONS

This clinical report represents the first English-language recommendations for the management of pediatric AP. Future aims should include prospective multicenter pediatric studies to further validate these recommendations and optimize care for children with AP.

Effects on nutritional care practice after implementation of a flow chart-based nutrition support protocol in an intensive care unit

Background

Enteral nutrition (EN) is associated with improved outcome in critically ill patients and is more affordable. We compared nutritional care practice in our ICU before and after modification of our nutrition support protocol: Several comprehensive documents were substituted with one flow chart and early EN was encouraged.

Design

Retrospective observational study.

Methods

Nutritional data were collected from admission up to 7 days in 25 patients before and 25 patients after protocol modification.

Results

The percentage of patients receiving EN within 72 hr of admission increased from 64% before to 88% after protocol modification. Cumulative percentage energy from EN during ICU days 1–4 increased from 26–89% of total kcal. Overall amount of nutrition administered enterally increased, with a corresponding marked decline in use of parenteral nutrition. Pre‐modification, >80% of patients received >65% of their calculated nutrition requirements by ICU Day 4; post‐modification this goal was achieved by Day 7.

Blended foods for tube-fed children: a safe and realistic option? A rapid review of the evidence

With the growing number of children and young people with complex care needs or life-limiting conditions, alternative routes for nutrition have been established (such as gastrostomy feeding). The conditions of children and young people who require such feeding are diverse but could relate to problems with swallowing (dysphagia), digestive disorders or neurological/muscular disorders. However, the use of a blended diet as an alternative to prescribed formula feeds for children fed via a gastrostomy is a contentious issue for clinicians and researchers. From a rapid review of the literature, we identify that current evidence falls into three categories: (1) those who feel that the use of a blended diet is unsafe and substandard; (2) those who see benefits of such a diet as an alternative in particular circumstances (eg, to reduce constipation) and (3) those who see merit in the blended diet but are cautious to proclaim potential benefits due to the lack of clinical research. There may be some benefits to using blended diets, although concerns around safety, nutrition and practical issues remain.

Enteral Administration of Twice-Daily Dolutegravir and Rilpivirine as a Part of a Triple-Therapy Regimen in a Critically Ill Patient with HIV

The administration of antiretroviral therapy (ART) in intubated critically ill patients may be challenging. Limited pharmacokinetic data exist characterizing the effects of crushed ART with subsequent enteral administration on antiretroviral drug concentrations or the clinical impact on HIV virologic suppression. We report a case of a 27-year-old HIV-positive male with presumed multidrug-resistant HIV and a diagnosis of lymphoma who required enteral ART administration after intensive care unit admission. Crushed twice-daily dolutegravir (separated from enteral nutrition by 2 hours) and rilpivirine (concurrently with a bolus feed) were administered via an orogastric tube. Therapeutic drug monitoring for both dolutegravir and rilpivirine demonstrated antiretroviral absorption via the enteral route (both values slightly below the therapeutic laboratory reference range) with continued virologic suppression.

Executive summary: evaluation of the evidence to support practice guidelines for nutritional care of preterm infants-the Pre-B Project

Preterm birth (infants born at <37 wk of gestational age) is a significant clinical and public health challenge in the United States and globally. No universally accepted practice guidelines exist for the nutritional care of preterm infants. To address the current state of knowledge and to support systematic reviews that will be used to develop evidence-informed guidance, a consortium consisting of the American Academy of Pediatrics, the ASN, the American Society for Parenteral and Enteral Nutrition, the Academy of Nutrition and Dietetics, the Food and Drug Administration, the CDC, the USDA/Agricultural Research Service (USDA/ARS), and the Eunice Kennedy Shriver National Institute of Child Health and Human Development/NIH initiated the Pre-B Project. The project included the constitution of 4 thematic working groups charged with the following tasks: 1) develop a series of topics/questions for which there is sufficient evidence to support a systematic review process to be conducted by the Academy of Nutrition and Dietetics' Evidence Analysis Library (EAL), leading to the development of new guidelines for nutritional care of preterm infants, and 2) develop a targeted research agenda to address priority gaps in our understanding of the role of nutrition in the health and development of preterm/neonatal intensive care unit infants. This review consists of a project overview including a summary of a workshop hosted by the USDA/ARS Children's Nutrition Research Center and summary reports of the 4 working groups established to address the following themes: 1) nutrient specifications, 2) clinical/practical issues in enteral feeding, 3) gastrointestinal and surgical issues, and 4) current standards for assessing infant feeding outcomes. These reports will serve as the basis for the ultimate guideline development process to be conducted by the Academy of Nutrition and Dietetics' EAL.

Can enteral antibiotics be used to treat pneumonia in the surgical intensive care unit? A clinical outcomes and cost comparison

Background:

Controlling healthcare costs without compromising patient care is a focus given recent healthcare changes in the United States. The purpose of this study was to assess clinical improvement in surgical intensive care unit (SICU) patients initiated on or transitioned to enteral antibiotics compared to those who solely receive intravenous (IV) antibiotic therapy for treatment of bacterial pneumonia.

Materials and Methods:

This retrospective cohort study included patients with a positive quantitative respiratory culture being treated for bacterial pneumonia in a SICU from 1/1/09 to 3/31/11. Two distinct patient groups were identified: Those treated with IV antibiotics exclusively (IV) and those either initiated on or transitioned to enteral antibiotics within 4 days of antibiotic initiation (PO). The primary endpoint of clinical improvement was assessed on day of antibiotic discontinuation.

Results:

A total of 647 patients were evaluated; 124 met inclusion criteria (30 patients PO group and 94 IV group). There was no difference in clinical improvement (86.7 PO vs 72.3% IV, P = 0.14) or recurrence (10 PO vs. 12.8% IV, P > 0.99) between groups. Secondary outcomes of duration of mechanical ventilation, ICU and hospital length of stay, and all-cause mortality were also similar. Antibiotic and infection-related costs were significantly decreased in the PO group ($1,042 vs $697, P = 0.04; $20,776 vs $17,381, P = 0.012, respectively).

Conclusions:

SICU patients initiated on or transitioned to PO antibiotics for pneumonia had similar clinical outcomes, but significantly less infection-related and antibiotic costs compared to those receiving IV therapy. Further, prospective studies are warranted.

Nutrition management of diabetes in acute care

Nutrition therapy in hospital includes the integration of diabetes into the care plan for the presenting condition, basic self-management education and care coordination to promote optimal glycemic control in hospital and an appropriate plan for discharge. Estimated nutrient requirements for people with diabetes are the same as those for the general population, and diets should be designed based on individual metabolic needs. Distribution of meals and snacks should employ a consistent carbohydrate meal-planning approach for both patient safety and management of glycemia. Referral to a registered dietitian for a full assessment is warranted for those at higher risk for hyperglycemia, including those on insulin or nutrition support. Consideration may be given to the use of lower carbohydrate oral nutrition supplements. A team approach should be employed to ensure there is coordination among blood glucose testing, insulin administration and meal timing. Self-management education should focus on patient safety, and an appropriate plan for discharge should be created to manage the ongoing needs of patients with this chronic disease.

Enteral nutrition in neonatal and pediatric extracorporeal life support: a survey of current practice

PURPOSE

The purpose of this study was to characterize enteral (EN) nutrition practices in neonatal and pediatric patients receiving extracorporeal life support (ECLS).

METHODS

A Web-based survey was administered to program directors and coordinators of Extracorporeal Life Support Organization centers providing neonatal and pediatric ECLS. The survey assessed patient and clinical factors relating to the administration of EN.

RESULTS

A total of 122 responses (122/521, 23.4%) from 96 institutions (96/187; 51.3%) were received. One hundred fifteen provided neonatal or pediatric ECLS, and 84.2% reported utilizing EN during ECLS. 55% and 71% of respondents provide EN 'often' or 'always' for venoarterial and venovenous ECLS, respectively. EN was reported as given 'often' or 'always' by 24% with increased vasopressor support, 53% with "stable" vasopressor support, and 60% with weaning of vasopressor support. Favorable diagnosis for providing EN includes respiratory distress syndrome, pneumonia, asthma, trauma/post-operative, pulmonary hemorrhage, and infectious cardiomyopathy. Vasopressor requirement and underlying diagnosis were the primary or secondary determinant of whether to provide EN 81% and 72% of the time. 38% reported an established protocol for providing EN.

CONCLUSION

EN support is common but not uniform among neonatal and pediatric patients receiving ECLS. ECLS mode, vasopressor status, and underlying diagnosis play an important role in the decision to provide EN.

Nutrition support protocols and their influence on the delivery of enteral nutrition: a systematic review

BACKGROUND

Malnutrition remains prevalent in critically ill adults and is associated with poor outcomes and increased cost of hospitalization.

AIM

To (a) determine whether implementation of a nutrition support protocol improves delivery of nutrients in critically ill patients, and (b) evaluate whether patients receiving nutrition support based on a protocol have better outcomes than those who do not.

METHODS

CINHAL and PUBMED databases were searched utilizing keywords "model," "nutrition," intensive care," "algorithm," "critical care," "protocol," and "feeding guidelines." Selection criteria included original studies published in English with publication date between January 1, 2005, and December 31, 2010; a critically ill adult population; and level 1 or 2 studies. Studies were collected and reviewed by a single reviewer. Data extraction and quality assessment were assured utilizing a standardized form. A narrative description of results was provided due to variability in methods and outcome measures of included studies.

RESULTS

Ninety-nine studies emerged and 22 studies were considered for inclusion. Four studies were selected. Use of a nutrition support protocol was found to lead to increased efficacy in the delivery of nutrients via the enteral route.

LINKING EVIDENCE TO ACTION

The use of a nutrition support protocol appears to increase the efficacy of enteral nutrition delivery. Further research is needed to determine the effect of increased enteral nutrition adequacy on patient outcomes. The use of an evidenced-based protocol is recommended to improve protein and energy delivery in the critically ill.

An update on diets in clinical practice

Ketogenic diet therapies involve a collaborative healthcare team and therefore are typically offered in tertiary care centers. Centers that utilize these therapies with frequency gain valuable experience and become skilled in their practice. This chapter is a summary from the presentations of 5 practitioners including a nurse, pharmacist, and 3 dietitians who shared their expertise during the clinical session of the 2012 International Symposium.
