Neonates and infants are more vulnerable to infections and show reduced responses to vaccination. Consequently, repeated immunizations are required to induce protection and early life vaccines against major pathogens such as influenza are yet unavailable. Formulating antigens with potent adjuvants, including immunostimulators and delivery systems, is a demonstrated approach to enhance vaccine efficacy. Yet, adjuvants effective in adults may not meet the specific requirements for activating the early life immune system...

BACKGROUND: A dietary supply of docosahexaenoic acid (DHA) and arachidonic acid (AA) is critical for neonatal retinal development. Both are absent/minimal in parenteral nutrition (PN) using soy-oil emulsions ([SO] Intralipid®) traditionally used for neonatal intestinal failure. In contrast, fish-oil emulsions ([FO] Omegaven®) are enriched in DHA/AA. The aim of this study was to compare retinal function and fatty acid content in neonatal piglets fed PN with SO or FO. METHODS: Two-5-day-old piglets were randomly allocated to SO (n = 4) or FO (n = 4), provided at equivalent doses (5g/kg/d)...

Overdose of cardiovascular medications such as beta blockers and calcium channel blockers cause impaired cardiac contractility, vasoplegia, and/or rhythm disturbances. In addition to conventional management of limiting absorption, increasing elimination and hemodynamic support intravenous (IV) calcium infusion, hyperinsulinemia-euglycemia therapy, glucagon infusion, and IV lipid emulsion have been tried. Extracorporeal circulatory assist device support has been reported as a rescue therapy in overdose refractory to maximal medical therapy...

Elderly people are at high risk for influenza-related morbidity and mortality due to progressive immunosenescence. While toll-like receptor (TLR) agonist containing adjuvants, and other adjuvants, have been shown to enhance influenza vaccine-induced protective responses, the mechanisms underlying how these adjuvanted vaccines could benefit the elderly remain elusive. Here, we show that a split H1N1 influenza vaccine (sH1N1) combined with a TLR4 agonist, glucopyranosyl lipid adjuvant formulated in a stable oil-in-water emulsion (GLA-SE), boosts IgG2c:IgG1 ratios, enhances hemagglutination inhibition (HAI) titers, and increases protection in aged mice...

Condyloma acuminatum (CA) is a common sexually transmitted disease caused by human papillomavirus (HPV). Podophyllotoxin (POD), a cytotoxic compound, is able to effectively treat HPV; however, the severe irritation side effects of POD restrict its use as a treatment for CA. The aim of the present study was to construct novel POD‑loaded nanostructured nanolipid carriers (POD‑NLCs) and evaluate their physicochemical characteristics and cytotoxicity. POD‑NLCs (0.5%) were prepared using emulsion‑evaporation and low temperature‑solidification methods with optimized conditions and preparations...

Lipid oxidation is one of the most important reasons for the compromised shelf life of food emulsions. A major bottleneck in unravelling the underlying mechanisms is the lack of methods that provide a rapid, quantitative and comprehensive molecular view on lipid oxidation in these heterogeneous systems. In this study, the unbiased and quantitative nature of 1H NMR was exploited to assess lipid oxidation products in mayonnaise, a particularly oxidation-prone food emulsion. An efficient and robust procedure was implemented to produce samples where the 1H NMR signals of oxidation products could be observed in a well resolved and reproducible manner...

BACKGROUND: The purpose of this study was to characterize fatty acid profiles (FAPs) in parenteral nutrition (PN)-dependent infants with intestinal failure-associated liver disease (IFALD) receiving soybean oil-based lipid emulsion (SO) doses of ∼3 and ∼1 g/kg/d. METHODS: Prospectively collected data were retrospectively reviewed. Serum FAPs of patients <1 year old who experienced development of IFALD while receiving standard PN with SO were examined before transitioning to a fish oil-based lipid emulsion for IFALD treatment...

Intestine failure-associated liver disease (IFALD) is widely recognized as a lethal complication of long-term parenteral nutrition. The pathophysiology of IFALD is poorly understood but appears to be multifactorial and related to the inflammatory state in the patient with intestinal failure (IF). Visceral transplantation for IFALD includes variants of intestine, liver, or combined liver and intestine transplantation. Graft selection for an individual patient depends on the etiology of intestinal failure, abdominal and vascular anatomy, severity of IFALD, and potential for intestinal rehabilitation...

At an intensive care unit, four neonates died consecutively within 80 minutes. Citrobacter freundii was isolated from blood samples of the 4 patients. It was also cultured from the leftover SMOFlipid that had been infused intravenously into the patients. In this in vitro study, we evaluated the bacterial growth kinetics and change in size of fat globules in SMOFlipid contaminated with C. freundii. Following the growth of bacteria, pH of SMOFlipid decreased to < 6, and the number of fat globules larger than 5 μm increased...

Designing soft, palatable and nutritious texture-modified foods for the elderly is a challenge for food technologists. The aim of this work was to produce and characterize emulsion-gelled microparticles (EGM) made from whey protein isolate (WPI) and sodium alginate (NaAlg) that may be used to modify the rheology of liquid foods and as carriers of lipids and lipophilic nutrients and bioactives. Olive oil microdroplets became embedded in the WPI/NaAlg gel matrix in the form of an emulsion produced by ultrasound (US) or high-speed blending (HSB)...

There are many examples of bioactive proteins and peptides that would benefit from oral delivery through functional foods, supplements, or medical foods, including hormones, enzymes, antimicrobials, vaccines, and ACE inhibitors. However, many of these bioactive proteins are highly susceptible to denaturation, aggregation or hydrolysis within commercial products or inside the human gastrointestinal tract (GIT). Moreover, many bioactive proteins have poor absorption characteristics within the GIT. Colloidal systems, which contain nanoparticles or microparticles, can be designed to encapsulate, retain, protect, and deliver bioactive proteins...

Salts reduction/substitution have gained a lot interest from food industry since the US Food and Drug Administration (FDA) has issued a draft guidance for salt reduction. However how changes of salts in food formulation could influence lipid oxidation is still not fully understood. Using oil-in-water emulsions stabilized by a natural emulsifier - lecithin at pH 7.0 as a model system, this study evaluated how salts affect the physical parameters of the emulsion, the chelating activity of lecithin and thus the lipid oxidation of these emulsions...

Lipid emulsions have been associated with liver injury. Newer mixed emulsions (ML), such as SMOFlipid (Fresenius Kabi, Germany), are thought to be more hepatoprotective than soybean-based emulsions (SL), such as Intralipid (Baxter). Pediatric studies comparing long-term use between the 2 are limited. This study compares the severity of hepatic injury between a prospective cohort of hospitalized children on ML (n = 20) and a historical age- and diagnosis-matched cohort of hospitalized children on SL (n = 20)...

BACKGROUND: Parenteral nutrition (PN) is frequently needed in neonatal intensive care. The use of standard PN has emerged as an easy-to-prescribe approach that allows one to have on-site, ready-to-use PN. The aim of this study was to test the physicochemical stability and sterility of 2 specific PN solutions as well as simulate Y-site compatibility with lipid injectable emulsions (ILE). METHODS: Our study considered 2 standard ILE-free PN solutions according to neonatal weight...

We present the case of a 26-year-old man who was brought into our emergency department in cardiorespiratory arrest, having taken Kratom 24 h previously. Despite multi-organ support, he deteriorated and died from cardiorespiratory failure and hypoxic brain damage 12 h later. Lipid emulsion was given, with significant temporary improvement in the cardiorespiratory failure. Kratom is derived from Mitragyna speciosa, a tropical deciduous and evergreen tree in the coffee family, and is native to Southeast Asia, and its leaves are used as a legal high in some parts of the world...

We present the case of a 51-year-old woman admitted to our intensive care unit following an intentional overdose of a calcium channel antagonist and a beta blocker. The resultant hypotension was reversed with glucagon, noradrenaline, calcium and high-dose insulin. Despite these interventions, she remained vasoplegic and received a delayed, standard dose of intralipid. Subsequently, the vasoplegia resolved rapidly, and the vasopressor was stopped. Here, we review the management of overdose of calcium channel and beta-adrenergic receptor blockers, concentrating on the pharmacology of lipid emulsion therapy...

Neonatal units have started to switch from using conventional soy-based to alternate lipid emulsions, like SMOFlipid. SMOFlipid has been associated with an improvement in biochemical parameters and delays progression of parenteral nutrition-associated liver disease (PNALD). This retrospective epoch study aimed to compare clinically relevant neonatal outcomes in preterm infants (< 32 weeks), receiving SMOFlipid versus Intralipid. We compared clinical outcomes in two epochs-epoch 1 (Intralipid, October 2013-June 2015) versus epoch 2 (SMOFlipid, July 2015-March 2017)...
