Speech and Swallowing Outcomes Following Surgical Resection with Immediate Free Tissue Transfer Reconstruction for Advanced Osteoradionecrosis of the Mandible Following Radiation Treatment for Head and Neck Cancer.

Despite recent advances in the radiation techniques used for the treatment of head and neck cancer (HNC) including intensity-modulated radiotherapy (IMRT), mandibular osteoradionecrosis (ORN) remains a significant complication. Advanced stage ORN is managed surgically with resection and immediate free tissue transfer reconstruction. An evaluation of the functional speech and swallowing outcomes was undertaken for patients undergoing surgical management of advanced ORN. We retrospectively reviewed consecutive patients, at a single, tertiary cancer centre, who underwent surgical resection for advanced Notani grade III ORN. Outcomes investigated included use and duration of tracheostomy and swallowing and speech status using Performance Status Scale for Head and Neck Cancer Normalcy of Diet (PSS-NOD) and Understandability of Speech (PSS-Speech) at baseline and 3 months following surgery. Ten patients underwent surgical resection with free tissue transfer reconstruction between January 2014 and December 2019. Two patients required supplemental nutrition via a gastrostomy at three months post surgery. As per the PSS-NOD data half of the patients' (n = 5) diet remained stable (n = 2) or improved (n = 3) and half of the participants experienced a decline in diet (n = 5). The majority of patients had no speech difficulties at baseline (n = 8). The majority of patients' speech remained stable (n = 8) with two patients experiencing a deterioration in speech clarity following surgery. Well-designed studies with robust, sensitive multidimensional dysphagia and communication assessments are required to fully understand the impact of surgical management of advanced ORN using resection with free tissue transfer reconstruction.

Minimizing Variance in Gastroschisis Management Leads to Earlier Full Feeds in Delayed Closure.

BACKGROUND: Limited guidance exists regarding appropriate timing for feed initiation and advancement in gastroschisis. We hypothesized that implementation of a gastroschisis management protocol would allow for standardization of antibiotic and nutritional treatment for these patients. METHODS: We conducted a retrospective comparison of patients with simple gastroschisis at two pediatric hospitals before and after initiation of our gastroschisis care protocol. Complicated gastroschisis and early mortality were excluded. The control group extended from January 2012 to January 2014 and the protocol group from July 2014 to July 2016. Variables of interest included time to feed initiation, time to goal feeds, length of stay, and National Surgical Quality Improvement Program-defined complications. We performed a subgroup analysis for primary versus delayed gastroschisis closure. Statistical analyses, including F-tests for variance, were conducted in Prism. RESULTS: Forty-seven patients with simple gastroschisis were included (control = 22, protocol = 25). Protocol compliance was 76% with no increase in complication rates. There was no difference in length of stay or time from initiation to full feeds overall between the control and protocol groups. However, neonates who underwent delayed closure reached full feeds significantly earlier, averaging 9 d versus 15 d previously (P = 0.04). CONCLUSIONS: For infants undergoing delayed closure, the time to full feeds in this group now appears to match that of patients undergoing primary closure, indicating that delayed closure should not be a reason for slower advancement. Additional studies are needed to assess the impact of earlier full enteral nutrition on rare complications and rates of necrotizing enterocolitis.

Daily rhythms of intestinal cholecystokinin and pancreatic proteases activity in Senegalese sole juveniles with diurnal and nocturnal feeding.

The influence of diurnal and nocturnal feeding on daily rhythms of gut levels of cholecystokinin (CCK) and the activity of two key pancreatic proteases, trypsin and chymotrypsin, were examined in juveniles of Senegalese sole (Solea senegalensis), a species with nocturnal habits. Four feeding protocols were performed: P1) One morning meal; P2) Six meals during the light period; P3) Six meals during the dark period; and P4) 12 meals during 24 h. Daily activity patterns of both proteases were remarkably similar and showed a high correlation in all the experimental protocols. In P1, daily patterns of CCK and digestive enzymes showed a single maximum. In P2, CCK levels exhibited two peaks. Digestive enzymes activities showed slightly delayed peaks compared to CCK, although their daily fluctuations were not significant. In P3, intestinal CCK concentration exhibited two peaks at the end of light and dark periods, but only the second one was significant. The first maximum level of chymotrypsin activity occurred 4 h after the first CCK peak, while the second one coincided with the second CCK peak. Fluctuations of trypsin activity were not significant. In P4, CCK concentration showed three small peaks. Digestive enzymes daily fluctuations were not significant, although they showed an inverted trend with respect to CCK. The daily pattern of the gut CCK content in our study is in agreement with the anorexigenic function of this hormone. Our results support the existence of a negative feedback regulatory loop between CCK and pancreatic proteolytic enzymes in Senegalese sole juveniles.

The impact of removing gastric residual volume monitoring and enteral nutrition rate titration in adults receiving mechanical ventilation.

BACKGROUND: Monitoring gastric residual volume (GRV) and titrating enteral nutrition (EN) towards goal rate are common practices in the intensive care unit (ICU) despite limited supportive evidence. We investigated the effect of removal of GRV monitoring and commencing EN at goal rate had on EN provision in mechanically ventilated ICU patients. METHODS: We conducted a single-centre, pre-post implementation study, in a 10-bed ICU comprising 181 patients with ventilation ≥48 h and given EN within 24 h of intubation. EN adequacy, expressed as the proportion of patients receiving ≥90% of the prescribed volume during the first 24 h of feeding, was compared before and after implementation. Secondary outcomes included EN adequacy over entire ICU stay; incidence of gastrointestinal intolerance in terms of vomiting, abdominal distension, and GRV >200 ml; prokinetic use; onset of a ventilator-associated condition; ventilation duration; length of stay; and mortality. RESULTS: After intervention, the proportion of patients meeting ≥90% of their prescribed EN volume within the first 24 h of feeding increased by 38.1% (pre: 46.4%, 95% confidence interval [CI]: 36.7-56.3; post: 84.5%, 95% CI: 75.8-91.2; p < 0.001). Over their entire ICU stay, the proportion of patients meeting ≥90% of their prescribed EN volume increased by 21.4% (pre: 61.9%, 95% CI: 52.0-71.1; post: 83.3%, 95% CI: 74.4-90.2; p = 0.001). Gastrointestinal intolerance reduced by 34.0% (pre: 80.4%, 95% CI: 71.8-87.5; post: 46.4%, 95% CI: 36.0-57.1; p < 0.001) and fewer prescribed prokinetic agents (pre: 57.7%, 95% CI: 47.8-67.3; post: 23.8%, 95% CI: 15.6-33.6; p < 0.001). CONCLUSIONS: Removal of GRV monitoring and commencing EN at goal resulted in significantly increased EN provision during the first 24 h of feeding and entire ICU stay with reduced prokinetic use and gastrointestinal complications.

Superlattice stacking by hybridizing layered double hydroxide nanosheets with layers of reduced graphene oxide for electrochemical simultaneous determination of dopamine, uric acid and ascorbic acid.

A self-assembled periodic superlattice material was obtained by integrating positively charged semiconductive sheets of a Zn-NiAl layered double hydroxide (LDH) and negatively charged layers of reduced graphene oxide (rGO). The material was used to modify a glassy carbon electrode which then is shown to be a viable sensor for the diagnostic parameters dopamine (DA), uric acid (UA) and ascorbic acid (AA). The modified GCE displays excellent electrocatalytic activity towards these biomolecules. This is assumed to be due to the synergistic effects of (a) excellent interfacial electrical conductivity that is imparted by direct neighboring of conductive rGO to semiconductive channels of LDHs, (b) the superb intercalation feature of LDHs, and (c) the enlarged surface with an enormous number of active sites. The biosensor revealed outstanding electrochemical performances in terms of selectivity, sensitivity, and wide linear ranges. Typically operated at working potentials of -0.10, +0.13 and + 0.27 V vs. saturated calomel electrode, the lower detection limits for AA, DA and UA are 13.5 nM, 0.1 nM, and 0.9 nM, respectively, at a signal-to-noise ratio of 3. The sensor was applied to real-time tracking of dopamine efflux from live human nerve cells. Graphical abstract Schematic of the preparation of a superlattice self-assembled material by integrating positively charged semiconductive sheets of Zn-NiAl layered double hydroxide (LDH) with negatively charged reduced graphene oxide (rGO) layers. It was applied to simultaneous electrochemical detection of dopamine (DA), uric acid and ascorbic acid.

Postoperative Enteral Nutrition Guidelines Reduce the Risk of Intestinal Failure-Associated Liver Disease in Surgical Infants.

OBJECTIVE: To assess the effectiveness of postoperative feeding guidelines in reducing the incidence and severity of intestinal failure-associated liver disease (IFALD) among infants. STUDY DESIGN: Two cohorts of infants <6 months old undergoing intestinal surgery were compared: preguideline (retrospective data from 2007 to 2013; n = 83) and postguideline (prospective data from 2013 to 2016; n = 81). The guidelines included greater initial enteral nutrition volumes of 20 mL/kg/d and daily feeding advancement if tolerated. The primary outcomes were incidence of IFALD (peak direct bilirubin [DB] >2 mg/dL) and severity (DB >5 mg/dL for moderate-severe). Multiple logistic regression was used to determine the odds of developing IFALD. Other outcomes were time to reach 50% and 100% goal calories from enteral nutrition and the incidence of necrotizing enterocolitis after feeding. RESULTS: The incidence of IFALD decreased from 71% to 51% (P = .031), and median peak DB decreased from 5.7 to 2.4 mg/dL (P = .001). After adjusting for diagnosis and prematurity, the odds of developing IFALD of any severity were reduced by 60% (OR 0.40, 95% CI 0.20-0.85), and the odds of developing moderate-to-severe IFALD were reduced by 72% (OR 0.28, 95% CI 0.13-0.58) with guideline use. Time to reach 50% enteral nutrition decreased from a median of 10 to 6 days (P = .020) and time to reach 100% enteral nutrition decreased from 35 to 21 days (P = .035) with guideline use. The incidence of necrotizing enterocolitis after initiating enteral nutrition did not change (5% vs 9%, P = .346). CONCLUSIONS: Implementation of feeding guidelines reduced time to reach feeding goals, significantly reducing IFALD incidence and severity.

Expert consensus to weight an adherence score for audit and feedback of practices that prevent necrotizing enterocolitis in very low birth weight infants.

OBJECTIVE: Necrotizing enterocolitis (NEC) is a catastrophic abdominal complication threatening the life of premature infants, but adoption of prevention and early recognition practices differs as do NEC rates in Neonatal Intensive Care Units (NICUs). The purpose of this research was to validate and weight an evidence-based adherence score (aka NEC-Zero Adherence Score) to prevent and foster timely recognition of NEC. STUDY DESIGN: An electronic Delphi (e-Delphi) approach was used to identify consensus. NEC experts were recruited via the NEC Society and surveyed until consensus and stability criteria for the Delphi were met (≥70% consensus and mean responses changed <15% between rounds). RESULTS: Expert panelists (n=22) were experienced (M=17.6, SD 11years) and predominately physicians (68%) or neonatal nurse practitioners (18%). Consensus (>70% by item) supported a 10 point score. Points were distributed across 1) an exclusive human milk diet (5 points), 2) standardized feeding protocols (3 points), 3) antibiotic stewardship (1 point), and 4) a unit-specified approach to early recognition (1 point). Withholding feeding during transfusion was controversial (M=0.50, SD 0.73) and met consensus criteria to drop from the score. CONCLUSIONS: Holding feeding during transfusion was dropped from the score. Relationships between the score and unit NEC rates as well as its utility for use in audit and feedback should be studied in the future.

Results of a Feeding Protocol in Patients Undergoing the Hybrid Procedure.

Neonates with single-ventricle physiology are at increased risk of developing gastrointestinal morbidities. Feeding protocols in this patient population have been shown to decrease feeding complications after the Norwood procedure, but no data exist to determine the effectiveness of a feeding protocol in patients undergoing the hybrid procedure. Goal of this study was to examine the impact of a standardized feeding protocol on the incidence of overall postoperative gastrointestinal morbidity after the hybrid procedure. Retrospective chart review was performed on neonates undergoing the hybrid procedure. Neonates were divided into two groups, pre-feeding protocol (pre-FP), which encompassed the years 2002-2008, and post-feeding protocol (post-FP), which encompassed the years 2011-2014. Preoperative, operative, and postoperative data were collected. T test or Fisher's exact test was used for analysis. p < 0.05 was considered significant. Seventy-three neonates were in the pre-FP and 52 neonates were in the post-FP. There were no significant differences between the pre-FP and the post-FP in cardiac diagnosis (62 HLHS, 11 other vs. 39 HLHS, 13 other, respectively). Pre-FP underwent hybrid procedure later than the post-FP (9.1 ± 5.8 vs. 5.7 ± 3.4 days, respectively, p < 0.01) and achieved full enteral feeds earlier than the post-FP (3.2 + 2.9 vs. 7.8 + 3.9 days, respectively, p < 0.01). The incidence of necrotizing enterocolitis was higher in the pre-FP versus post-FP [11.0 % (8/65) vs. 5.8 % (3/49), respectively, p = 0.36]. Though not significant, the incidence of necrotizing enterocolitis decreased by almost 50 % after initiating a feeding protocol in patients undergoing the hybrid procedure. This is consistent with previous studies showing beneficial results of a feeding protocol in this complex patient population.

Design and conduct of a randomized controlled feeding trial in a residential setting with mitigation for COVID-19.

BACKGROUND: Evaluating effects of different macronutrient diets in randomized trials requires well defined infrastructure and rigorous methods to ensure intervention fidelity and adherence. METHODS: This controlled feeding study comprised two phases. During a Run-in phase (14-15 weeks), study participants (18-50 years, BMI, ≥27 kg/m2) consumed a very-low-carbohydrate (VLC) diet, with home delivery of prepared meals, at an energy level to promote 15 ± 3% weight loss. During a Residential phase (13 weeks), participants resided at a conference center. They received a eucaloric VLC diet for three weeks and then were randomized to isocaloric test diets for 10 weeks: VLC (5% energy from carbohydrate, 77% from fat), high-carbohydrate (HC)-Starch (57%, 25%; including 20% energy from refined grains), or HC-Sugar (57%, 25%; including 20% sugar). Outcomes included measures of body composition and energy expenditure, chronic disease risk factors, and variables pertaining to physiological mechanisms. Six cores provided infrastructure for implementing standardized protocols: Recruitment, Diet and Meal Production, Participant Support, Assessments, Regulatory Affairs and Data Management, and Statistics. The first participants were enrolled in May 2018. Participants residing at the conference center at the start of the COVID-19 pandemic completed the study, with each core implementing mitigation plans. RESULTS: Before early shutdown, 77 participants were randomized, and 70 completed the trial (65% of planned completion). Process measures indicated integrity to protocols for weighing menu items, within narrow tolerance limits, and participant adherence, assessed by direct observation and continuous glucose monitoring. CONCLUSION: Available data will inform future research, albeit with less statistical power than originally planned.

Zebrafish Feed Intake: A Systematic Review for Standardizing Feeding Management in Laboratory Conditions.

Zebrafish are one of the most used animal models in biological research and a cost-effective alternative to rodents. Despite this, nutritional requirements and standardized feeding protocols have not yet been established for this species. This is important to avoid nutritional effects on experimental outcomes, and especially when zebrafish models are used in preclinical studies, as many diseases have nutritional confounding factors. A key aspect of zebrafish nutrition is related to feed intake, the amount of feed ingested by each fish daily. With the goal of standardizing feeding protocols among the zebrafish community, this paper systematically reviews the available data from 73 studies on zebrafish feed intake, feeding regimes (levels), and diet composition. Great variability was observed regarding diet composition, especially regarding crude protein (mean 44.98 ± 9.87%) and lipid content (9.91 ± 5.40%). Interestingly, the gross energy levels of the zebrafish diets were similar across the reviewed studies (20.39 ± 2.10 kilojoules/g of feed). In most of the reviewed papers, fish received a predetermined quantity of feed (feed supplied). The authors fed the fish according to the voluntary intake and then calculated feed intake (FI) in only 17 papers. From a quantitative point of view, FI was higher than when a fixed quantity (pre-defined) of feed was supplied. Also, the literature showed that many biotic and abiotic factors may affect zebrafish FI. Finally, based on the FI data gathered from the literature, a new feeding protocol is proposed. In summary, a daily feeding rate of 9-10% of body weight is proposed for larvae, whereas these values are equal to 6-8% for juveniles and 5% for adults when a dry feed with a proper protein and energy content is used.

Proactive Use of a Human Milk Fat Modular in the Neonatal Intensive Care Unit: A Standardized Feeding Protocol.

An exclusive human milk diet (EHMD) and standardized feeding protocols are two critical methods for safely feeding very low birth weight (VLBW) infants. Our institution initiated a standardized feeding protocol for all VLBW infants in 2018. In this protocol, a human milk fat modular was used only reactively when an infant had poor weight gain, fluid restriction, or hypoglycemia. As part of our NICU quality improvement program, internal utilization review data revealed a potential opportunity to improve growth and reduce costs. While maintaining the EHMD, a simple feeding guideline process change could provide cost savings without sacrificing caloric density or growth. We examined this process change in pre-post cohorts of VLBW infants. METHODS: Our revised feeding protocol, established in October 2021, called for a human milk fat modular (Prolact CR) to be added to all infant feeding when parenteral nutrition (PN) and lipids were discontinued. The human milk fat modular concentration is 4 mL per 100 mL feed, providing approximately an additional 2 kcal/oz. We tracked data to compare (1) the use of the human milk fat modular, (2) the use of the human milk +8 fortifier, (3) overall growth before and after feeding protocol changes, and (4) cost differences between protocols. RESULTS: Thirty-six VLBW infants were followed prospectively upon the introduction of the revised feeding protocol. In the revised era, the need for human milk +8 fortifier decreased from 43% to 14%. The decrease in the cost of a more costly fortifier provided a cost savings of USD 2967.78 on average per infant. Overall growth improved from birth to discharge, with severe malnutrition declining from 3.3% to 2.7% and moderate malnutrition declining from 37% to 8%. CONCLUSIONS: With the proactive use of a human milk fat modular in a standardized feeding protocol, our VLBW infants showed improved growth, lower malnutrition rates, and decreased use of higher caloric fortifiers.

Implementing a physician-driven feeding protocol is not sufficient to achieve adequate caloric and protein delivery in a paediatric intensive care unit: A retrospective cohort study.

BACKGROUND AND AIMS: Daily caloric and protein intake is crucial for the management of critically ill children. The benefit of feeding protocols in improving daily nutritional intake in children remains controversial. This study aimed to assess whether the introduction of an enteral feeding protocol in a paediatric intensive care unit (PICU) improves daily caloric and protein delivery on day 5 after admission and the accuracy of the medical prescription. METHODS: Children admitted to our PICU for a minimum of 5 days who received enteral feeding were included. Daily caloric and protein intake were recorded and retrospectively compared before and after the introduction of the feeding protocol. RESULTS: Caloric and protein intake was similar before and after introduction of the feeding protocol. The prescribed caloric target was significantly lower than the theoretical target. The children who received less than 50% of the caloric and protein targets were significantly heavier and taller than those who received more than 50%; the patients who received more than 100% of the caloric and protein aims on day 5 after admission had a decreased PICU length of stay and decreased duration of invasive ventilation. CONCLUSION: The introduction of a physician-driven feeding protocol was not associated with an increase in the daily caloric or protein intake in our cohort. Other methods of improving nutritional delivery and patient outcomes need to be explored.

A standardized feeding protocol ensured recommended nutrient intakes and prevented growth faltering in preterm infants < 29 weeks gestation.

BACKGROUND & AIMS: Nutrition is a cornerstone of postnatal care to prevent compromised growth and support short- and long-term health outcomes in preterm infants. We aimed to evaluate nutritional intakes and growth among infants <29 weeks gestation after implementation of a standardized feeding protocol. METHODS: This is an observational cohort secondary analysis of data from the ImNuT study (Immature, Nutrition Therapy, NCT03555019). To reduce variations in nutritional practice and ensure accommodation to current guidelines, we developed a standardized feeding protocol. Detailed information on actual nutritional intakes, growth and biochemistry was prospectively collected and assessed from birth to 36 weeks postmenstrual age (PMA). RESULTS: Median (range) gestational age and birth weight were 26+6 (22+6-28+6) weeks and 798 (444-1485) g. Energy and macronutrient intakes progressively increased from birth through transition to exclusive enteral feeds. Parenteral nutrition was weaned at median (IQR) day 11 (9, 14) when nutritional requirements were met by exclusively enteral feeds. Infants exhibited a median (IQR) weight loss of 7.8% (5.7, 11.6) and regained birth weight by day 8 (7, 11). Average velocity in weight, length and head circumference from birth to 36 weeks PMA were in accordance with target growth rates; median (IQR) 15.8 (14.7, 17.7) g/kg/d, 1.1 (0.98, 1.3) cm/week and 0.82 (0.83, 0.89) cm/week. At 36 weeks PMA, only 3% of infants exhibited moderate growth faltering (decline in weigh-for-age z score >1.2 from birth), and none severe. CONCLUSIONS: In infants <29 weeks gestation, the standardized feeding protocol was well tolerated. Nutrient intakes and growth were close to recommendations.

The nutritional impact of a feeding protocol for infants on high flow nasal cannula therapy.

BACKGROUND: Clinicians may be reluctant to feed patients on high-flow nasal cannula (HFNC) therapy, despite studies suggesting it is beneficial and safe. We describe the implementation of a feeding protocol for patients with bronchiolitis on HFNC and determine its effect on nutrition goals. METHODS: Prospective bedside data on enteral volume, feed interruptions, and aspiration events were collected on patients with bronchiolitis who were <24 months of age, treated with HFNC, and fed per a developed protocol. Exclusion criteria included history of prematurity <32 weeks, congenital heart disease, or positive-pressure ventilation before feeding. Length of intensive care unit and hospital stay was compared with both a concurrent cohort (CC) of patients not fed per the protocol and a retrospective cohort (RC) admitted prior to protocol creation. RESULTS: Seventy-eight patients met the criteria for the prospective study arm: 24 patients were included in the CC, and 74 were included in the RC. Seventy-one percent of prospective patients received enteral nutrition (EN) on HFNC day 1 vs 42% of the CC. In the prospective cohort, feed interruption occurred in 23% of patients and was associated with higher flow rates; however, no aspiration events occurred. Patients fed per protocol were fed 8-10 h sooner and discharged 1 day earlier than those in the RC. CONCLUSION: The use of a feeding protocol for patients with bronchiolitis on HFNC was safe and associated with shorter time to initiate EN and shorter length of hospital stay.

The impact of a multifaceted quality improvement program on the incidence of necrotizing enterocolitis in very low birth weight infants.

BACKGROUND: Necrotizing enterocolitis (NEC) is a multifactorial gastrointestinal disease which mostly occurs in very low birth weight (VLBW) infants. In addition to decreasing gestational age (GA) or birth weight (BW), artificial formula, delayed initiation or rapidly advanced feeding, severe anemia and systemic infections were associated with NEC. Several studies demonstrated that breast milk, standardized feeding advancement regimens and treatment of anemia are associated with less incidence of NEC. It is not known if including all these interventions in one multifaceted program will lead to significant reduction in NEC. METHODS: The NICU team at The George Washington University Hospital created a multifaceted interdisciplinary quality improvement project to tackle several aspects of NEC prevention that addressed researched risk factors for NEC. The program was made of four quality improvement protocols: 1) Standardized Structured Feeding Program, 2) Feeding Intolerance Management Algorithm, 3) Enteral Osmolality Control Tool, and 4) Packed Red Blood Cell (RBC) Standardized Transfusion Protocol. This time-series, quasi experimental study design examined the differences in the incidence of NEC between infants with BW < 1500 g who were admitted to the GW Hospital NICU before and after the program implementation. RESULTS: Data from 408 VLBW infants were included in the study. Although not statistically significant, there was a decreasing trend of NEC incidence in the post-implementation group (n = 199) compared to the pre-implementation group (n = 209), (3.5% vs. 5.3%, p = 0.88). The trend in the incidence of NEC declined further after the introduction of RBC transfusion protocol which was introduced ten month after starting the other elements of the program. CONCLUSION: Integration of the multifaceted quality improvement program may be associated with a decline in the occurrence of NEC. Further analysis with a larger sample size is required to determine if the changes seen are statistically significant.

Clinical Outcomes of Enteral Feeding Protocol Via Percutaneous Endoscopic Gastrostomy: A Single-Center, Retrospective Study.

BACKGROUND: The development of the endoscopic technique has resulted in an increasing number of patients undergoing percutaneous endoscopic gastrostomy (PEG) insertion; however, the protocols for increasing the volume of feeding formula after PEG insertion have not been established. Therefore, we compared the clinical outcomes of patients receiving low- and high-volume increase in enteral feeding formula. METHODS: A total of 215 patients who underwent PEG insertion between January 2016 and March 2019 were included. They were divided into 2 groups according to the increase in volume of feeding formula: the low-volume group (n = 135) received ≤150 mL/d, and the high-volume group (n = 80) received ≥300 mL/d. Patient characteristics, procedure, and feeding-related clinical outcomes were retrospectively reviewed using medical records. RESULTS: The adverse events of the feeding protocol did not significantly differ between the 2 groups. The number of days needed to attain the calorie targets was significantly lower in the high-volume group than in the low-volume group (5.4 ± 3.0 vs 2.4 ± 1.5; P < .001). The duration of supplemental parenteral nutrition and the length of hospitalization were also significantly lower in the high-volume group (3.9 ± 3.3 vs 1.2 ± 2.2; P < .001 and 5.8 ± 2.7 vs 4.6 ± 2.6; P = .007, respectively). CONCLUSION: To rapidly attain the calorie targets in appropriately selected patients with PEG insertion, a high-volume increase in daily feeding can safely be recommended given the favorable outcomes.

The effect of standardized feeding protocol on early outcome following gastroschisis repair: A systematic review and meta-analysis.

BACKGROUND: Improved post-operative outcomes following gastroschisis repair are attributed to advancement in perioperative and post-operative care and early enteral feeding. This study evaluates the role of standardized postoperative feeding protocols in gastroschisis. STUDY DESIGN: A systematic review and meta-analysis of studies published from January 2000 to April 2019 in MEDLINE, EMBASE, Cochrane Library databases and Google Scholar was conducted. Primary outcomes were duration to full enteral feeding and cessation of parenteral nutrition. Secondary outcomes included days to first enteral feeding, length of stay, compliance, complication and mortality rates. Meta-analysis was done using the RevMan Analysis Statistical Package in Review Manager (Version 5.3) using a random effects model and reported as pooled Risk Ratio and Mean Difference. p-value < 0.05 was considered statistically significant. RESULTS: Eight observational cohort studies were identified and their data analyzed. Significant heterogeneity was noted for some outcomes. Standardized feeding protocols resulted in fewer days to first enteral feeding by 3.19 days (95% CI: -4.73, -1.66, p < 0.0001) than non-protocolized feeding, less complication rates, reduced mortality and better compliance to care. The duration of parenteral nutrition and time to full enteral feeding were not significantly affected. CONCLUSION: Protocolized feeding post-gastroschisis repair is associated with early initiation of enteral feeding. There is a likelihood of reduced rates of sepsis; shorter duration of parenteral nutrition, length of hospital stay and time to full enteral feeding. However, the latter trends are not statistically significant and will require further studies best accomplished with a prospective randomized trial or more cohort studies.

Evidence-Based Practices Reduce Necrotizing Enterocolitis and Improve Nutrition Outcomes in Very Low-Birth-Weight Infants.

BACKGROUND: Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency in preterm infants. Survivors may suffer both short- and long-term morbidities. Current evidence suggests that the incidence of NEC can be reduced by standardizing the care delivery in addressing key risk factors including an altered gut microbiome, use of formula milk, hyperosmolar feeds, and unrestricted use of high-risk medications METHODS: Since 2014, the department has a workgroup who analyzed all cases of NEC within a month of diagnosis to identify preventable risk factors. Existing evidence-based quality improvement strategies were revised and new ones were implemented sequentially over the next 4 years. These strategies include (1) a standardized feeding protocol, (2) early initiation of enteral feeding using human milk, (3) optimization of the osmolality of preterm milk feeds using standardized dilution guidelines for additives, and (4) promotion of healthy microbiome by use of probiotics, early oral care with colostrum and by restricting high-risk medications and prolonged use of empirical antibiotics RESULTS: Baseline characteristics of the patients including sex, gestational age, and birth weight were similar during the study period. After implementing the evidence-based practices successively over 4 years, the incidence of NEC in very- low birth-weight (VLBW) infants dropped from 7% in 2014 to 0% (P < .001) in 2018. The duration of parenteral nutrition, use of central line, and days to full feeds were also reduced significantly (P < .05) CONCLUSION: Adopting evidence-based best practices resulted in a significant decrease in the incidence of NEC and improved the nutrition outcomes in VLBW infants.

Feeding protocol deviation after esophagectomy: A retrospective multicenter study.

BACKGROUND: Esophagectomy is associated with high postoperative morbidity rates, which can result in decreased quality of life and impaired recovery. Implementation of enhanced recovery after surgery (ERAS) protocols have made a great impact in optimizing postoperative recovery. However, the best timing to start oral intake is still unclear. Conservative feeding protocols have been developed with a nil-by-mouth period in the first postoperative days to reduce postoperative complication rates (e.g. anastomotic leakage and pneumonia). This study aimed to evaluate adherence to the feeding protocol following minimal invasive esophagectomy and identify reasons for protocol deviation. METHODS: All consecutive patients who underwent an esophagectomy with gastric tube reconstruction between 2014 and 2016 in two high-volume hospitals in the Netherlands were retrospectively analyzed. All patients were planned to receive enteral tube feeding via jejunostomy directly after surgery. Data regarding postoperative feeding related symptoms (e.g. nausea, vomiting, regurgitation) and adherence to the postoperative feeding protocol were gathered. RESULTS: A total of 186 patients were included. Feeding protocol deviation was observed in 109 patients (59%) and was significantly more common in patients with anastomotic leakage, chyle leakage, and acute respiratory distress. Postoperative feeding related symptoms were present in 107 patients (58%) and were significantly more common in female patients and patients with a cervical anastomosis. CONCLUSION: In this study, more than half of the patients deviated from the intended feeding protocol after esophagectomy. Postoperative complications appeared to be the main reason for feeding protocol deviation. This study shows that a predefined feeding protocol including an oral fasting period is often violated because of complications.

Early Transition to Microdiets Improves Growth, Reproductive Performance and Reduces Skeletal Anomalies in Zebrafish (Danio rerio).

Zebrafish is a model species with a high variability of feeding regimes among fish facilities. The use of live feeds for early life stages is a common practice, and few studies have focused early weaning into microdiets. The lack of standardized feeding protocols among research facilities promotes discrepancies in biological performances, and few studies relate dietary regimes to zebrafish development. The objective of this work was to assess the effect of an early transition into microdiets in zebrafish development by evaluating growth, survival, reproductive performance, and skeletal anomalies. These parameters were assessed in one group exclusively fed on Artemia nauplii and two groups fed on microdiets (commercial and experimental). Results showed that an early weaning with the two microdiets significantly improved zebrafish growth and reproductive performance, while a decrease in incidence of vertebral column anomalies was observed. A high survival was also maintained in fish fed microdiets at an early developmental stage when comparing to exclusive Artemia nauplii feeding. In conclusion, early weaning with high quality microdiets is beneficial for zebrafish growth, reproductive performance, and skeletal development, contributing to the standardization of zebrafish husbandry practices.
