Abstract
Small peptide formulas versus standard polymeric formulas for enteral nutrition in critically ill patients with acute gastrointestinal injury (AGI) have been a topic of debate. A systematic review and meta-analysis were conducted to compare their clinical and nutritional outcomes. Relevant studies from January 1980 to June 2022 were searched in PubMed, Cochrane, and Embase databases. Randomized controlled trials involving AGI grade I-IV patients were included, while children, non-AGI patients, and non-critically ill patients were excluded. Results indicated no significant difference in all-cause mortality. Patients receiving small peptide formulas showed higher daily protein intake, greater albumin growth, and higher prealbumin levels. They also had shorter lengths of stay in the intensive care unit and hospital. Conversely, patients receiving standard polymeric formulas had a higher daily calorie intake. In conclusion, the choice of formula may not affect mortality in critically ill patients with AGI. Small peptide formulas were more conducive to increase daily protein intake, decrease intensive care unit and hospital length of stay. Further large-scale randomized controlled trials evaluating the effects of these two nutritional formulas on clinical and nutritional outcomes in critically ill patients with AGI are needed to confirm these results.

[PMID: 37840748 PMCID: PMC10568644 DOI: 10.3389/fmicb.2023.1242650] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 08/31/2023] [Indexed: 10/17/2023] Open
Abstract
Introduction Changes in the gut microbiota of patients with partial small intestinal obstruction (PSIO) have not been widely clarified. We aimed to explore bacterial diversity in a PSIO mouse model. Methods A PSIO mouse model was established using male C57BL/6 mice, and feces samples from the distal ileum and ileum epithelium tissues were collected. MiSeq sequencing of the 16S rRNA gene was conducted to characterize microbiota diversity and composition. RNA sequencing for differences in transcriptomic programming of the ileum tissue was performed between the PSIO and (Control) Ctrl groups. Results Bacterial diversity in the PSIO group was significantly lower than that in the controls. Pseudomonadota was predominant in the feces of the PSIO group. Unclassified_Muribaculaceae (p = 0.008) and Akkermansia (p = 0.007) were more abundant in the Ctrl group than those in the PSIO group. Furthermore, Escherichia_Shigella (p = 0.008) was more predominant in the feces of the PSIO group. The Kyoto Encyclopedia of Genes and Genomes pathways related to metabolism were depleted in the PSIO group. Pathways associated with intestinal fibrosis, including extracellular matrix-receptor interaction, focal adhesion, phosphoinositide 3-kinase (PI3K)-Akt signaling pathway and transforming growth factor (TGF)-beta signaling pathway, which were enriched in ileum epithelial tissue in the PSIO group. Conclusion PSIO can lead to changes in the predominant intestinal bacterial groups. Depleted functional profiles of the gut microbiota were identified in the PSIO group. Functional pathways associated with intestinal fibrosis were activated by PSIO. The potential regulation by the microbiota needs to be explored in the future.

Abstract
PURPOSE The aim of this study was to assess the risk factors for colistin-resistant carbapenemase-producing Enterobacterales (CR-CPE), and describe the mortality associated with this organism, in a low-income country. METHODS A descriptive, observational, and prospective multicenter study was carried out in Guayaquil, Ecuador. All patients with carbapenem-resistant Enterobacterales admitted between December 2021 and May 2022 were enrolled. Infection definitions were established according to the Centers for Disease Control and Prevention (CDC) protocols. The presence of carbapenemase-producing Enterobacterales was confirmed with a multiplex PCR for blaKPC, blaNDM, blaOXA-48, blaVIM, and blaIMP genes. MCR-1 production was studied molecularly, and MLST assays were carried out. RESULTS Out of 114 patients enrolled in the study, 32 (28.07%) had at least one positive sample for CR-CPE. Klebsiella pneumoniae ST512-KPC-3 was the most frequent microorganism isolated. Parenteral feeding, β-lactamase inhibitor use, recent hemodialysis, and renal failure were all considered independent risk factors for carrying CR-CPE. A mortality of 41.22% was detected, but we could not find any difference between colistin-resistant and colistin-susceptible CPE. MCR-1 production was not detected in any of the isolates studied. CONCLUSION A significant burden for CR-CPE was found in a South American country that was mainly caused by the high-risk clone K. pneumoniae ST512-KPC-3 and not mediated by mcr-1 production. Its acquisition involved parenteral feeding, β-lactamase inhibitor use, recent hemodialysis, and renal failure as independent risk factors, demonstrating the critical need for infection prevention and stewardship programs to avoid dissemination to other countries in the region.

Abstract
BACKGROUND AND AIMS Partially hydrolyzed guar gum (PHGG) is a water-soluble fiber supporting digestive health with well-established safety and efficacy. This open-label, single-arm, multicenter trial aimed to assess the tolerability and safety of a semi-elemental enteral formula containing PHGG at 12 g/L in tube-fed young children. METHODS Children aged 1-4 years with stable conditions requiring tube feeding to provide ≥80% of their nutritional needs received the study formula for seven days. Tolerability, safety, adequacy of energy/protein intake, and weight change were assessed. RESULTS Of 24 children (mean age 33.5 months; 10 [41.7%] female), 23 (95.8%) commenced treatment and 18 (75%) completed the study. All children had underlying neuro-developmental disabilities, often in association with gastrointestinal comorbidities requiring treatment for constipation (70.8%) or gastroesophageal reflux (66.7%). The formula was well-tolerated by 19 (82.6%) subjects, while 4 (17.4%; 95% CI: 5%, 39%) subjects withdrew early from the study due to gastrointestinal intolerance. The mean (SD) percentage energy and protein intake across the 7-day period were 103.5% (24.7) and 139.5% [50], respectively. Weight remained stable over the 7-day period (p = 0.43). The study formula was associated with a shift towards softer and more frequent stools. Pre-existing constipation was generally well controlled, and 3/16 (18.7%) subjects ceased laxatives during the study. Adverse events were reported in 12 (52%) subjects and were deemed 'probably related' or 'related' to the formula in 3 (13%) subjects. Gastrointestinal adverse events appeared more common in fiber-naïve patients (p = 0.09). CONCLUSION The present study indicates that the study formula was safe and generally well tolerated in young tube-fed children. CLINICALTRIALS GOV IDENTIFIER NCT04516213.

Abstract
The use of enteral nutrition (EN) continues to increase given benefits. However, with this increase in use, it is also becoming evident that enteral feeding intolerance (EFI) is also quite prevalent, leading to the inability to meet nutrition needs in many patients. Given the wide variability in the EN population as well as the number of formulas available, there is not a clear consensus regarding the best approach to EFI management. One approach that is emerging to improve EN tolerance is the use of peptide-based formulas (PBFs). PBFs refer to enteral formulas containing proteins that have been enzymatically hydrolyzed to dipeptides and tripeptides. These hydrolyzed proteins are often combined with higher medium-chain triglyceride content to generate an enteral formula that is essentially easier to absorb and utilize. Emerging data demonstrate that the use of PBF in patients with EFI may improve clinical outcomes along with a corresponding reduction in healthcare utilization and potentially the cost of care. This review aims to navigate through key clinical applications and benefits of PBF and to discuss relevant data shared in the literature.

Assessing the Effects of a Perioperative Nutritional Support and Counseling in Gastrointestinal Cancer Patients: A Retrospective Comparative Study with Historical Controls. Biomedicines 2023; 11:biomedicines11020609. [PMID: 36831145 PMCID: PMC9953606 DOI: 10.3390/biomedicines11020609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 02/13/2023] [Accepted: 02/15/2023] [Indexed: 02/22/2023] Open
Abstract
The aim of this study was to investigate the effects of perioperative nutritional therapy care in gastrointestinal (esophageal, gastric, gastroesophageal) cancer patients on nutritional status and disease progression (complications, hospitalization, mortality). We considered 62 gastrointestinal cancer patients treated at the Center for Integrated Oncology (CIO), University Hospital Bonn, Germany (August 2017-July 2019). Of these, 42 patients (as intervention group: IG) received pre- and postoperative nutritional support with counseling, while 20 patients (as historical control group CG) received only postoperative nutritional therapy. Several clinical parameters, such as Body Mass Index (BMI), nutritional risk screening (NRS), phase angle, postoperative complications, length of hospital stay, and mortality, were determined. There were significantly fewer patients with gastric cancer/CDH1 gene mutation and more with esophageal cancer in IG (p = 0.001). Significantly more patients received neoadjuvant therapy in IG (p = 0.036). No significant differences were found between the groups regarding BMI, NRS, complications, length of hospital stay, and mortality. However, the comparison of post- and preoperative parameters in IG showed a tendency to lose 1.74 kg of weight (p = 0.046), a decrease in phase angle by 0.59° (p = 0.004), and an increase in NRS of 1.34 points (p < 0.001). Contrary to prior reports, we found no significant effect of perioperative nutritional therapy care in gastrointestinal cancer patients; however, the small cohort size and infrequent standardization in nutritional status may possibly account for the variance. Considering that oncological pathways and metabolic nutritional pathways are interrelated, dividing patients into subgroups to provide a personalized nutritional approach may help in improving their treatment.
