Abstract
BACKGROUND Nutrition therapy is essential in critically ill adults. Little is known about appropriate nutrition therapy in patients with severe coronavirus disease 2019 (COVID-19) infection. METHODS This was a retrospective, observational study in adult patients with confirmed COVID-19 infection receiving mechanical ventilation. Data regarding patient demographics and nutrition therapy were collected. Patients that received enteral nutrition within 24 hours of starting mechanical ventilation were compared with patients starting enteral nutrition later. The primary outcome was inpatient length of stay. Propensity score matching was conducted to control for baseline differences in patient groups. RESULTS One hundred fifty-five patients were included in final analysis. Patients who received enteral nutrition within 24 hours received a significantly greater daily amount of calories (17.5 vs 15.2 kcal/kg, P = .015) and protein (1.04 vs 0.85 g/kg, P = .003). There was no difference in length of stay (18.5 vs 23.5 days, P = .37). The propensity score analysis included 100 patients. Following propensity scoring, significant differences in daily calorie (17.7 [4.6] vs 15.1 [5.1] kcal/kg/d, P = .009) and protein (1.03 [0.35] vs 0.86 [0.38] g/kg/d, P = .014) provision remained. No differences in length of stay or other outcomes were noted in the propensity score analysis. CONCLUSION Initiation of enteral nutrition within 24 hours was not associated with improved outcomes in mechanically ventilated adults with COVID-19. No harm was detected either. Future research should seek to clarify optimal timing of enteral nutrition initiation in patients with COVID-19 who require mechanical ventilation.

Abstract
(1) Background: The tolerance of preterm newborns for the high nutritional intakes given by parenteral nutrition (PN) is still debated because of the risk of metabolic complications. Despite enteral nutrition (EN) being the preferred route of nutrition, an exclusive enteral feeding is not always possible, as in preterm newborns, the gut is immature and less tolerant of EN. We aimed to study the impact of a minimal enteral feeding (MEF) on the possible early metabolic complications of PN in a cohort of preterms with gestational age at birth GA ≤ 29 + 6/7 weeks of postmenstrual age. (2) Methods: We divided the study sample in two cohorts: 1) Late-Feeding (cohort 1), newborns who received MEF starting from the 8th day of age, and (2) Early-Feeding (cohort 2), newborns who received MEF, consisting of the administration of at least 4-5 mL/kg/day by the enteral route, in the first 7 days of age. The primary outcome of the study was the rate of at least one metabolic complication, including hyperglycemia, hypertriglyceridemia, or metabolic acidosis. (3) Results: We enrolled 80 newborns (Late-Feeding cohort 51 vs. Early-Feeding cohort 29). The rate of all metabolic complications was statistically higher in the Late-Feeding cohort compared to the Early-Feeding cohort. Binary logistic regression analysis showed that late administration of MEF negatively influenced the rate of all metabolic complications. (4) Conclusions: Early minimal administration of EN is associated with less frequent PN-related metabolic side effects and a higher rate of survival in critically ill newborns.

Clinical nutrition (Edinburgh, Scotland). 2021;(3):1071-1076
Abstract
BACKGROUND & AIM: Neurocritically ill patients are more likely to be comatose and suffer from dysphagia, conditions that inevitably require nutritional support. Inappropriate nutritional support may lead to refeeding syndrome (RFS). This study aimed to explore the incidence and outcome of RFS in neurocritically ill patients. METHODS We conducted a retrospective study among neurocritically ill patients who received total enteral nutrition for >72 h in a university-affiliated hospital. RFS was defined as the occurrence of new-onset hypophosphatemia (<0.65 mmol/L) within 72 h of the commencement of nutritional support. The primary outcome was 6-month mortality. The secondary outcomes included 30-day mortality, neurocritical care unit (NCU) stay, and hospital length of stay. RESULTS A total of 328 patients were enrolled, and 56 (17.1%) of them developed RFS within 72 h of nutrition support. Significantly, we found that patients with high malnutrition universal screening tool (MUST) and sequential organ failure assessment (SOFA) scores were more likely to develop RFS. The occurrence of RFS was associated with a longer NCU stay, higher 30-day mortality and 6-month mortality, and poorer 6-month functional outcome. Moreover, RFS was identified as an independent risk factor for 6-month mortality. CONCLUSION RFS is not rare in neurocritically ill patients and is more likely to occur in patients with nutritional risk and more severe conditions. RFS is an independent risk factor for 6-month mortality in neurocritically ill patients.

Abstract
For intensive care unit (ICU) patients, injectable voriconazole (VRCZ) is difficult to use because the patients often develop acute kidney injury. Since many ICU patients have consciousness disturbance, oral ingestion of tablet formulation is also difficult, and administration of a suspension via enteral feeding tube is required when using VRCZ. In this study, we investigated the in vitro adsorption property of oral VRCZ to feeding tube and performed pharmacokinetic analysis of VRCZ prepared by powdering and simple suspension for ICU patients. VRCZ was tube-administered to five ICU patients at a loading dose of 300 mg and plasma VRCZ concentrations before and at 1, 2, 4, 8, 12 h after the first dose were measured using HPLC. Pharmacokinetic parameters were calculated by non-compartmental model analysis. The recovery rate of VRCZ after infusion of the suspension through feeding tube was 89.8 ± 8.3%, but the cumulative rates after the first and second re-infusion were 102.7 ± 20.7 and 99.3 ± 10.3%, respectively, suggesting almost no residual drug in the tube after re-infusion. Metabolic phenotype was extensive metabolizer (EM) in two patients and intermediate metabolizer (IM) in three patients. The values of total clearance (CLtot/F) calculated by moment analysis were 0.51 and 0.55 L/h/kg in two EM patients, and 0.09, 0.29 and 0.31 L/h/kg in three IM patients. The CLtot/F was apparently lower in IM patients compared to EM. In conclusion, powdered and suspended VRCZ administered via enteral feeding tube showed pharmacokinetics depending on CYP2C19 gene polymorphism, similar to that observed in usual oral administration.

Mori, T, Yoshioka, K
BMC emergency medicine. 2020;(1):56
Abstract
BACKGROUND Malnutrition often occurs in acute stroke patients receiving enteral tube feeding (ETF). Unless malnutrition is improved, their clinical outcome is poor. However, strategies to improve malnutrition in these patients have not been established. Branched-chain amino acids (BCAA) may enhance protein synthesis and attenuate inflammation. Our study aimed to investigate whether a leucine enriched BCAA dietary supplement (LEBDs) could quickly increase serum levels of albumin (Alb) or transthyretin (TTR) and decrease high-sensitivity C-reactive protein (CRP) in the development of severe malnutrition within a few days after stroke onset compared to standard BCAA dietary supplement (SBDs). METHODS We retrospectively included acute stroke patients who: 1) were admitted between August 2016 and July 2017; 2) underwent ETF for 7 days or longer after admission, and 3) underwent blood examination of Alb, TTR, and CRP on admission, the fifth day and the seventh day. We defined severe malnutrition as severe hypoproteinemia: decrease of TTR to less than 15 mg/dl on the 5th day. In LEBDs and SBDs groups, patients started to receive a dietary supplement containing leucine of 1.44 and 0. 72 g twice a day on the fifth day, respectively. We evaluated Alb (g/dl), TTR (mg/dl), and CRP (mg/dl) on admission, the fifth day, and the seventh day. RESULTS Twenty-nine patients met our inclusion criteria:15 in LEBDs and 14 in SBDs. In LEBDs and SBDs groups, the median Alb was 3.5 and 3.3 g/dl, TTR was 12.7 and 10.7 mg/dl, and CRP was 1.02 and 0.673 mg/dl on admission, respectively. In LEBDs, the median Alb and TTR decreased to 2.6 g/dl and 11.9 mg/dl, and CRP increased to 5.337 mg/dl on the fifth day. On the 7th day, TTR increased, and CRP decreased, although Alb did not improve. In SBDs, the median Alb and TTR decreased to 2.6 g/dl and 9.7 mg/dl, and CRP increased to 4.077 mg/dl on the fifth day. On the 7th day, Alb, TTR, and CRP did not improve. CONCLUSION In acute stroke patients receiving leucine enriched BCAA dietary supplement, quick improvements in transthyretin and CRP were observed.

Abstract
OBJECTIVE We aimed to investigate the frequency of necrotising enterocolitis (NEC) in infants with critical congenital heart disease (CCHD) hypothesising that preoperative enteral feeding does not increase the risk of NEC. BACKGROUND When NEC affects term infants, underlying risk factors such as asphyxia, sepsis or CCHD are often found. Due to fear of NEC development in infants with CCHD great caution is practised in many countries to defer preoperative enteral feeding, but in Sweden this is routinely provided. DESIGN, SETTING AND PATIENTS An observational study of all infants born with CCHD who were admitted to Queen Silvia Children's Hospital in Gothenburg between 2010 and 2017. The International Classification of Diseases 10th Revision diagnosis code of NEC was used to identify NEC cases in this group. Infants described as 'fully fed' or who were fed at least 45 mL/kg/day before cardiac surgery were identified. MAIN OUTCOME MEASURES NEC in infants with CCHD in relation to preoperative enteral feeding. RESULTS There were 458 infants with CCHD admitted during the study period. 408/458 were born at term and 361/458 required prostaglandin E1 before surgery. In total, 444/458 infants (97%) were fully fed or fed at least 45 mL/kg daily before cardiac surgery. Four of 458 infants developed NEC (0.9%). All four had other risk factors for NEC. CONCLUSIONS This study showed a low risk of NEC in term infants fed enterally before cardiac surgery. We speculate that preoperative enteral feeding of neonates with CCHD does not increase the risk of NEC development.

Nutrients. 2020;(1)
Abstract
(1) Background: Nutritional status can influence the quality of life (QoL) of cancer patients. (2) Methods: This subanalysis evaluated the impact of an oral oligomeric enteral nutrition (OEN) protocol on the QoL of patients with oncology treatment-related diarrhea (OTRD) in a multicenter, observational, prospective study (DIAPOENO study). QoL was assessed with the Nottingham Health Profile (NHP) at baseline and after eight weeks of OEN treatment. (3) In the overall population, all the NHP categories significantly improved after eight weeks of OEN treatment: energy levels (p < 0.001), pain (p < 0.001), emotional reactions (p < 0.001), sleep (p < 0.001), social isolation (p = 0.023), and physical abilities (p = 0.001). QoL improvement was higher in patients with improved or maintained nutritional status and in those with improved consistency of stools with the OEN protocol. However, QoL did not significantly improve in patients with worse nutritional status and with worse or maintained stool consistency with the OEN protocol. QoL improved regardless of disease severity. Multivariate logistic regression analysis showed that weight change was significantly associated with improved QoL (OR 2.90-5.3), except for social isolation, in models unadjusted and adjusted to age, sex, oncology treatment, and stool consistency. (4) Conclusion: In this subanalysis, the OEN protocol was associated with improved QoL.

Schmidt, SB, Boltzmann, M, Rollnik, JD
Clinical nutrition (Edinburgh, Scotland). 2020;(2):425-432
Abstract
BACKGROUND & AIMS Studies focusing on the nutritional status of neurological and neurosurgical early rehabilitation (NNER) patients are limited. The aim of the current study was to determine the nutritional status of NNER patients upon admission, to observe weight changes and to investigate the influence of nutritional status on complications and outcome. METHODS 109 enterally fed NNER patients were included in this prospective observational study. Weight changes, complications, neurological outcome scores (Early Rehabilitation Index [ERI], Barthel-Index [BI]) and the length of stay (LOS) were recorded. In addition, daily energy requirement was calculated and compared with daily intake to identify under-/optimally- and oversupplied patients. RESULTS A general weight loss was observed in the study group. Weight changes during rehabilitation differed between men and women as well as between under- and oversupplied patients. Nutritional supply during rehabilitation had no influence on the LOS and the change of neurological outcome scores, but significant differences in the frequency of nosocomial infections was observed between under-/optimally- and oversupplied patients. The nutritional status (weight group on admission) had a crucial impact on neurological outcome scores, indicated by lower BI at discharge in normal-compared to underweight patients. In addition, underweight + undersupplied patients showed a significantly lower improvement of the BI than underweight + oversupplied patients. To the contrary, underweight + oversupplied patients had a higher BI improvement than underweight + optimally supplied patients. CONCLUSIONS The nutritional status upon admission in combination with the nutritional supply during rehabilitation appears to have an impact on changes of neurological outcome scores.

Internal medicine journal. 2020;(1):77-85
Abstract
BACKGROUND Patients with anorexia nervosa (AN) are vulnerable to physiological decompensation and often require inpatient management by an eating disorders unit. AIMS Patients admitted to an Australian tertiary medical centre for medical stabilisation of AN were assessed as part of quality assurance. Analysis included: (i) medical complications during acute inpatient stabilisation; (ii) predictors of refeeding syndrome; (iii) predictors governing length of stay (LOS); and (iv) outcomes pre- and post-implementation of multidisciplinary treatment guidelines. METHODS A retrosepctive analysis of 95 consecutive admissions (60 individual patients) between November 2011 and August 2017 was performed. RESULTS Patients had a median LOS of 9.6 days (interquartile range 5.8-19.7) and a mean weight gain of 1.4 kg (standard deviation 2.9). Medical complications included the following: hypoglycaemia (11.6%) and refeeding electrolyte derangement (26.3%). Advancing age (odds ratio (OR) 1.06 per year, P = 0.019), nasogastric tube requirement (OR 3.4, P = 0.014) and Code Grey(s) (security calls) (OR 7.1, P = 0.010) were associated with refeeding electrolyte derangement. Parameters associated with increased LOS included the following: lower body mass index (P = 0.029), Code Grey(s) (P = 0.029) and tachycardia (P = 0.013). Following multivariate analysis, the post-guidelines implementation group required less intravenous fluid and electrolyte replacement, though had lower rates of refeeding electrolyte derangement (OR 0.33 (0.11-0.99)). CONCLUSION Patients with moderate to severe AN are at risk of dangerous medical complications, and older patients may have heightened predisposition to refeeding electrolyte derangement. Early identification of medically high-risk patients is imperative to implement timely, life-saving interventions.

Abstract
BACKGROUND & AIMS Stroke is the leading cause of disability in adult life. Oropharyngeal dysphagia occurs in 65-90% of patients, and its identification in the acute phase of stroke can prevent complications. The aim of this study was to verify whether oropharyngeal dysphagia during stroke hospitalization is associated with functional capacity, as assessed by the modified Rankin Scale (mRs), and mortality 90 days after stroke. MATERIALS AND METHODS A prospective cohort study evaluating 201 patients hospitalized in the Stroke Unit was carried out. Dysphagia was evaluated during hospitalization using both a specific protocol to evaluate swallowing biomechanics and the Functional Oral Intake Scale (FOIS), in which FOIS 1-3 reflects tube feeding, 4-5 reflects oral feeding requiring food consistency changes, and 6-7 reflects oral feeding with no changes in food consistency. An mRs≥3 at 90 days after discharge was considered disability. The data were adjusted for the National Institute of Health Stroke Scale score, sex, age, stroke-associated pneumonia, type of stroke, and presence of thrombolysis. The significance level was set at 5%. RESULTS Of the 201 patients evaluated, 42.8% (86) who had dysphagia were older, had a higher severity of stroke, and pneumonia rate. A FOIS score of 6-7 was a protective factor against disability (mRs≥3) (OR: 0.17; CI: 0.005-0.56; p = 0.004), and tube feeding use at hospital discharge increased the risk of mRs≥3 (OR: 14.97; CI: 2.68-83.65; p = 0.002) and mortality (OR: 9.79; CI: 2.21-43.4; p = 0.003) within 90 days after stroke. Pneumonia was the leading cause of death, however dysphagia and tube feeding at discharge were associated with death from any cause. CONCLUSION Dysphagia or tube feeding use at discharge are markers of poor prognosis after the first stroke. Our data suggest the importance of early evaluation of dysphagia and closely monitoring the tube fed patients following stroke.
