Ketogenicdiet versus standard high-carbohydrate nutrition in sepsis: a randomized controlled trial

Project description:Sepsis patients suffer from severe metabolic and immunologic dysfunction that may be amplified by standard nutritional approaches relying primarily on carbohydrates. We here hypothesize that a ketogenic diet improves sepsis treatment. We conducted a monocentric open-labeled randomized controlled trial enrolling 40 adult sepsis patients. Patients were randomly assigned to either ketogenic diet (KD) or standard high-carbohydrate nutrition for 14 days and followed up until day 30. The primary outcome measure was β-hydroxybutyrate (BHB) serum concentration on day 14. We assessed feasibility and safety of KD, as well as diet-associated clinical and immunological changes. The respective nutrition protocols were successfully applied, dropouts did not occur. Regression analysis revealed a greater increase in BHB concentrations from baseline to day 14 in KD patients compared to controls. Metabolic side effects were not observed under ketogenic diet. Ventilation-free, vasopressor-free, dialysis-free and ICU-free days significantly increased in patients under ketogenic diet. Transcriptome profiling of both CD4+ and CD8+ T cells at day 14 revealed substantial differential regulation of gene expression in the KD vs. the control group indicating a reduced T-cell activation and a shift towards a more regulated immunity.

Whey Protein-based Enteral Nutrition Support to Improve Protein Economy in Surgical Patients

Project description:A prospective, randomized and controlled study is proposed to establish whether an enteral nutrition support regimen based on pressurized whey protein and glucose improves the postoperative utilization of amino acid substrates compared to a drink based on glucose alone. The kinetics of protein metabolism (protein breakdown, protein synthesis and amino acid oxidation) will be investigated using stable isotope methodology before and after surgery in patients undergoing colon resection. Stable isotope infusions will be conducted one week before surgery and on the second postoperative day for two hours in the fasted state and for four hours while sipping the enteral nutrition support regimen. Patients will consume one of two enteral nutrition support regimens consisting of a drink containing either pressurized whey protein and glucose or glucose alone. It is hypothesized that an enteral nutrition support regimen based on pressurized whey protein and glucose promotes positive protein balance through increased protein synthesis or reduced protein breakdown compared to glucose alone.

Effect of early calf-hood nutrition on the transcriptomic profile of subcutaneous adipose in Holstein-Friesian bulls

Project description:The aim of this study was to investigate the effect of early calf-hood nutrition on the transcriptomic profile of subcutaneous adipose in Holstein-Friesian bulls and possible downstream effects on reproduction. Holstein Friesian bull calves with a mean (±S.D.) age and bodyweight of 19 (±8.2) days and 47.5 (±5.3) kg, respectively, were assigned to either a high (n=10) or low (n=10) plane of nutrition. Calves were fed in order to achieve an overall growth rate of 1.08 and 0.5 kg/day for the high and low plane of nutrition treatments, respectively. At 126 days of age, the bulls were euthanized using an intravenous overdose of sodium pentobarbitone and subcutaneous adipose tissue samples were harvested and RNAseq analysis was performed. At the end of the trial period, there were 745 genes differentially expressed in adipose tissue of bulls on the high plane of nutrition relative to those on the low plane of nutrition (P<0.05; FDR<0.05; fold change >2.0). Plane of nutrition altered the expression of genes involved in energy production and branched chain amino acid degradation. Plane of nutrition was also found to down regulate genes such as leptin and adiponectin which are known to effect reproductive function. This study identifies some of the molecular mechanisms regulated by feeding bulls a high plane of nutrition, which may be incorporated into future breeding programmes for artificial insemination centres.

Investigation of parenteral nutrition-induced hepatotoxicity using human liver spheroid co-cultures

Project description:Parenteral nutrition (PN) is typically administered to individuals with gastrointestinal dysfunction, a contraindication for enteral feeding and a need for nutritional therapy. When PN is the only energy source in patients, it is defined as total parenteral nutrition (TPN). TPN is a life-saving approach for different patient populations, both in infants and adults. However, despite numerous benefits, TPN can cause adverse effects, including metabolic disorders and liver injury. TPN-associated liver injury, known as intestinal failure-associated liver disease (IFALD), represents a significant problem affecting up to 90% of individuals receiving TPN. IFALD pathogenesis is complex, depending on the TPN components as well as on the patient’s medical conditions. Despite numerous animal studies and clinical observations, the molecular mechanisms driving IFALD remain largely unknown. The present study was set up to elucidate the mechanisms underlying IFALD. For this purpose, human liver spheroid co-cultures were treated with TPN mixture followed by RNA sequencing analysis. It was found that prolonged exposure to TPN substantially changes the transcriptome profile of liver spheroids and affects multiple metabolic and signaling pathways contributing to liver injury.

Effect of early-life plane of nutrition on the transcriptional profile of the hypothalamus in heifer calves

Project description:The objective of this study was to examine changes in hypothalamic gene expression of heifer calves offered varying planes of nutrition during early life. Angus X Holstein-Friesian heifer calves (19 ± 5 days of age, BW: 51.2 ± 7.8 kg, mean ± SD) were offered a high (HP, n=14) or moderate plane of nutrition (MP, n=15) from 3 to 21 weeks of age to achieve a target growth rate of 1.2 kg/d and 0.5 kg/d, respectively. At 21 weeks of age, all calves were euthanized and the hypothalamus of each calf recovered. RNA was extracted and hypothalamic gene expression examined using RNAseq. Compared with calves on the moderate plane of nutrition, a HP of nutrition altered the expression of 39 transcripts in the hypothalamus. Biological pathway analysis revealed these differentially expressed genes to be involved in pathways including acute phase response signalling, STAT3 pathway, and tight junction signalling. Additionally, biological functions affected by early life plane of nutrition included cell-to-cell signalling and interaction, molecular transport, small molecule biochemistry, behaviour, nervous system development and function, nucleic acid metabolism, and cellular function and maintenance.
