Home parenteral nutrition (HPN) is a life-saving therapy for patients who are not able to use their gastrointestinal tract. There are a number of complications associated with HPN, including metabolic bone disease, intestinal failure-associated liver disease (IFALD), and catheter-related bloodstream infections. We present a case of a 32-year-old HPN patient who initially developed biopsy-proven IFALD (total bilirubin, 2.4 mg/dL) while on long-term HPN. His HPN was initiated due to myopathic intestinal dysmotility and pseudo-obstruction when he was 15 years old...

Background: Information on the bioavailability of the essential mineral Mg2+ is sparse. Objective/Method: Evaluation of the present knowledge on factors influencing the bioavailability and intestinal absorption of Mg2+. Results: Mg2+ is absorbed via a paracellular passive and a transcellular active pathway that involves TRPM6/7 channel proteins. The bioavailability of Mg2+ varies within a broad range, depending on the dose, the food matrix, and enhancing and inhibiting factors...

Background: The stomach is an underestimated key interface between the ingesta and the digestive system, affecting the digestion and playing an important role in several endocrine functions. The quality of starter microbiota and the early life feeding of medium chain triglycerides may affect porcine gastric maturation. Two trials (T1, T2) were carried out on 12 and 24 cesarean-delivered piglets (birth, d0), divided over two microbiota treatments, but slaughtered and sampled at two or three weeks of age, respectively...

Phosphorylated tocopherols are a new class of lipid excipients that have demonstrated potential in pharmaceutical applications. Their ability to solubilise poorly water soluble drugs indicates their potential utility in improving bioavailability of drugs where solubility limits their bioavailability. In this study a commercial mixture of phosphorylated tocopherols, TPM was combined with medium chain triglyceride (MCT) as a formulation for CoQ10, and in vitro and in vivo performance compared to the effect of addition of alternative tocopherol-based excipients...

In response to an acute threat to homeostasis or well-being, the hypothalamic-pituitary-adrenocortical (HPA) axis is engaged. A major outcome of this HPA axis activation is the mobilization of stored energy, to fuel an appropriate behavioral and/ or physiological response to the perceived threat. Importantly, the extent of HPA axis activity is thought to be modulated by an individual's nutritional environment. In this study, we report that nutritional manipulations signaling a relative depletion of dietary carbohydrates, thereby inducing nutritional ketosis, acutely and chronically activate the HPA axis...

Congenital stenosis (partial obstruction) of the small intestine is uncommon in comparison to atresia (complete obstruction). The clinical manifestations of stenosis could be delayed up to several weeks post-delivery. We present a case wherein a baby with a prenatal ultrasound examination showed a suspicious picture of small bowel obstruction. However, the clinical manifestations after delivery and imaging studies were misleading and non-classic; therefore, the resection of the stenotic portion of the ileum was delayed until the baby was one month of age...

The primary objective of this study was to develop lipid-based self-microemulsifying drug delivery systems (SMEDDS) without using any organic cosolvents that would spontaneously form microemulsions upon dilution with water. Cosolvents were avoided to prevent possible precipitation of drug upon dilution and other stability issues. Different polysorbates, namely, Tween 20, Tween 40, Tween 60, and Tween 80, were used as surfactants, and Captex 355 EP/NF (glycerol tricaprylate/caprate) or its 1:1 mixture with Capmul MCM NF (glycerol monocaprylocaprate) were used as lipids...

Neuroblastoma (NB) is a pediatric malignancy characterized by a marked reduction in aerobic energy metabolism. Recent preclinical data indicate that targeting this metabolic phenotype by a ketogenic diet (KD), especially in combination with calorie restriction, slows tumor growth and enhances metronomic cyclophosphamide (CP) therapy of NB xenografts. Because calorie restriction would be contraindicated in most cancer patients, the aim of the present study was to optimize the KD such that the tumors are sensitized to CP without the need of calorie restriction...

BACKGROUND: UV radiation from the sun is the most common environmental stressor to damage the skin. It is now well established that photodamaged skin manifests signs of mild but chronic inflammation, termed as "inflammaging." Thus, there is an urgent need for anti-inflammatory regimes that can limit the damage caused by inflammation. OBJECTIVES: This study aimed to evaluate the possible palliative effects of a new topical nanoemulsion formulation containing tocotrienol-rich fraction (TRF) on UV-induced inflammation (erythema) of human skin...

This article summarizes the presentations given at an ESPEN Workshop on "Lipids in the ICU" held in Tel Aviv, Israel in November 2014 and subsequent discussions and updates. Lipids are an important component of enteral and parenteral nutrition support and provide essential fatty acids, a concentrated source of calories and building blocks for cell membranes. Whilst linoleic acid-rich vegetable oil-based enteral and parenteral nutrition is still widely used, newer lipid components such as medium-chain triglycerides and olive oil are safe and well tolerated...

BACKGROUND: The use of total parenteral nutrition can affect liver function, causing a series of problems such as cholestasis. The aim of this meta-analysis was to compare structured triglyceride- (STG-) based lipid emulsions with physical medium-chain triglyceride (MCT)/long-chain triglyceride (LCT) mixtures in patients who had undergone liver surgery to identify any differences between these two types of parenteral nutrition. METHODS: We searched the databases of PubMed, the Cochrane Library, Web of Science, EMBASE, and Chinese Biomedicine Database from January 2007 to March 2017 and included studies that compared STG-based lipid emulsions with physical MCT/LCT mixtures for surgical patients with liver disease...

The purpose of the study was to develop a parenteral docetaxel lipid microsphere to inhibit its 7-epidocetaxel conversion in vitro and in vivo. 7-epidocetaxel conversion as the main indicator was investigated to optimize the formulation and process. 10% medium-chain triglyceride/long-chain triglyceride (3:1) as the oil phase, egg lecithin E80 as the emulsifier and 0.02% NaHSO3 as the acidity regulator were selected to prepare docetaxel lipid microsphere. This study found that pH and temperature were dominant factors on the epimerization of docetaxel in lipid microsphere, and that optimum conditions were a pH of 5...

BACKGROUND AND OBJECTIVES: A prior meta-analysis showed favorable metabolic effects of structured triglyceride (STG) lipid emulsions in surgical and critically ill patients compared with mixed medium-chain/long-chain triglycerides (MCT/LCT) emulsions. Limited data on clinical outcomes precluded pharmacoeconomic analysis. We performed an updated meta-analysis and developed a cost model to compare overall costs for STGs vs MCT/LCTs in Chinese hospitals. METHODS AND STUDY DESIGN: We searched Medline, Embase, Wanfang Data, the China Hospital Knowledge Database, and Google Scholar for clinical trials comparing STGs to mixed MCT/LCTs in surgical or critically ill adults published between October 10, 2013 and September 19, 2015...

Nowadays, therapeutic indications for cannabinoids, specifically Δ(9)-tetrahydrocannabinol (THC) and Cannabidiol (CBD) are widening. However, the oral consumption of the molecules is very limited due to their highly lipophilic nature that leads to poor solubility at the aqueous environment. Additionally, THC and CBD are prone to extensive first pass mechanisms. These absorption obstacles render the molecules with low and variable oral bioavailability. To overcome these limitations we designed and developed the advanced pro-nanolipospheres (PNL) formulation...
