Article Abstract
Background: Soybean oil lipid emulsions have been implicated in the development of parenteral nutrition-associated cholestasis (PNAC) in premature infants. A recent mixed fatty acid emulsion containing soybean oil, medium-chain triglycerides (MCTs), olive oil, and fish oil may reduce the incidence of PNAC, but evidence remains conflicting. The aim of this study was to evaluate the effect of mixed fatty acid emulsion on PNAC in extremely low-birth-weight (ELBW) infants.
Methods: We performed a retrospective cohort study on ELBW infants from 2016 to 2022. ELBW infants who received MCT/long-chain triglyceride (LCT) lipid emulsion or mixed fatty acid emulsion were compared. The primary outcome was the incidence of PNAC. Secondary outcomes included peak levels of direct bilirubin and bronchopulmonary dysplasia. Multivariable analysis was performed to adjust for potential confounders.
Results: A total of 180 ELBW infants were reviewed in this study. Twenty-six of 99 patients (26.2%) in the mixed fatty acid emulsion group and 29 of 81 patients (35.8%) in the MCT/LCT lipid emulsion group developed PNAC (P = 0.17). There was no significant difference in median peak direct bilirubin and the rate of bronchopulmonary dysplasia. The results remained consistent after adjusting for potential confounders. Time to PNAC, rate of rise of direct bilirubin, and age of direct bilirubin normalization were not statistically different between groups.
Conclusions: Compared with MCT/LCT lipid emulsion, mixed fatty acid emulsion did not reduce the incidence or degree of PNAC in ELBW infants.

Microbial consortia, involving two or more microorganisms, have been explored for pest management purposes, despite concerns regarding competitive exclusion among entomopathogenic fungi that may undermine synergistic effects. However, the precise molecular mechanisms governing entomopathogen competition in vivo remain inadequately elucidated. Here, we investigate competitive exclusion dynamics between two prominent entomopathogens, Metarhizium robertsii and Beauveria bassiana.

Background: Intravenous lipid emulsions are a key component of parenteral nutrition, and their fatty acid compositions may influence immune responses and clinical outcomes.
Methods: This retrospective cohort study conducted from January 2020 to December 2022 compared clinical outcomes of hospitalized non-critical care patients receiving parenteral nutrition with either mixed oil or soybean oil lipid emulsions for at least 48 h. The primary outcome was a composite of the presence of pneumonia, urinary tract infection, or an intra-abdominal collection diagnosed within 14 days of initiating parenteral nutrition.

This study investigated the effects of five representative biocarriers-biochar (BC), activated carbon (AC), nano-magnetite (NM), zero-valent iron (ZVI), and polyurethane sponge (PUS)-on chain elongation (CE) from ethanol/acetate in anaerobic systems. All carriers enhanced CE to varying extents. BC and NM significantly increased caproate yields (6032.

This study evaluated the effect of a nutraceutical supplementation (NS) and Mediterranean hypocaloric diet (MHD) on hepatic steatosis indices (HSIs), γ-glutamyl transferase (γGT), and lipid profile in adults with hyperlipidemia and nonalcoholic fatty liver disease (NAFLD). In vitro study on HepG2 cells explored potential molecular mechanisms. A retrospective study was conducted on 45 overweight/obese subjects (19 M) prescribed MHD with/without NS.

The study aimed to determine whether confinement with TMR during the first 21 DIM, followed by grazing supplemented with partial mixed ration (PMR), alleviates negative energy balance, enhancing productive performance and accelerating the resumption of ovarian cyclicity in primiparous and multiparous dairy cows, relative to a control group managed on grazing supplemented with PMR after calving. Following calving, 16 primiparous and 24 multiparous Holstein dairy cows were blocked and randomly distributed into 2 treatments: one included grazing plus supplementation with PMR after calving (T0), while the other one involved confinement with TMR ad libitum during the first 21 DIM and the same feeding management of T0 from d 22 onwards until 60 DIM (T21). Primiparous cows showed no significant differences between treatments in milk production.
