BACKGROUND: Thiamine has a crucial role in energy production, and consequently thiamine deficiency (TD) has been associated with cardiac failure, neurological disorders, oxidative stress (lactic acidosis and sepsis) and refeeding syndrome (RFS). This review aims to explore analytical methodologies of thiamine compound quantification and highlight similarities, variances and limitations of current techniques and how they may be relevant to patients. CONTENT: An electronic search of Medline, PubMed and Embase databases for original articles published in peer-reviewed journals was conducted...

BACKGROUND AND AIM: The optimal timing of oral refeeding in acute pancreatitis is unclear. This study aimed to perform a systematic review with meta-analysis of randomized controlled trials (RCTs) that compared early oral refeeding with standard oral refeeding in acute pancreatitis. METHODS: PubMed, the Cochrane library, and the Igaku-Chuo-Zasshi database were searched in order to identify RCTs eligible for inclusion in the systematic review. The weighted mean differences (WMDs) or odds ratios (ORs) with 95% confidence intervals (CIs) were calculated...

Aims: The recovery of body weight after a period of caloric restriction is accompanied by an enhanced efficiency of fat deposition and hyperinsulinemia-which are exacerbated by isocaloric refeeding on a high fat diet rich in saturated and monounsaturated fatty acids (SFA-MUFA), and poor in polyunsaturated fatty acids (PUFA), and associated with a blunting of de novo lipogenesis in adipose tissue and liver. As high fat diets rich in PUFA have been shown to limit the excess fat deposition and improve glucose homeostasis, we investigated here the extent to which de novo lipogenesis in liver and adipose tissues (white and brown), as well as hepatic oxidative stress, are influenced by refeeding on diets rich in PUFA...

The marine mixotrophic ciliate Mesodinium rubrum is known to acquire chloroplasts, mitochondria, nucleomorphs, and nucleus from its cryptophyte prey, particularly from species in the genera, Geminigera and Teleaulax. The sequestered prey nucleus and chloroplasts are considered to support photosynthesis of M. rubrum. In addition, recent studies have shown enlargement of the retained prey nucleus in starved M. rubrum and have inferred that enlargement results from the fusion of ingested prey nuclei. Thus far, however, little is known about the mechanism underlying the enlargement of the prey nucleus in M...

Calorie restriction (CR) is an effective intervention to prevent chronic diseases including cancer. Although many factors, i.e., sex hormones, IGF-I and mTOR have been studied in response to CR, the molecular mechanisms of CR remain to be identified. Our objective was to determine the short and long-term effects of different CR protocols on pro-inflammatory cytokines. Our hypothesis was that Intermittent CR (ICR) would result in greater inhibition of pro-inflammatory serum cytokines compared to Chronic CR (CCR) as we previously found ICR to be more protective in the prevention of mammary tumor development...

Refeeding hypophosphatemia remains a serious and common complication during the early phases of nutritional rehabilitation and weight restoration for patients with anorexia nervosa. Typically, the risk of refeeding hypophosphatemia diminishes after the first 1-2 weeks of the refeeding process and thus, frequent monitoring serum phosphorus levels becomes less important as refeeding proceeds. Herein, we describe a case of persistent recurrent hypophosphatemia in a male-to-female transgender patient with severe anorexia nervosa...

The authors sought to increase the number of days when burn service patients receive 100% of prescribed enteral nutrition. The authors first performed a retrospective review of 37 patients (group 1) receiving enteral nutrition. The authors then created and implemented a nurse-directed feeding algorithm, placing patients into three age groups addressing maximum hourly infusion rates, high residual limits, initiating feeding, refeeding residuals, and replacing formula. The authors then performed a prospective review of 37 patients (group 2) fed utilizing the new algorithm...

The aim of the present work was to further explore the physiological roles of muscle-derived IL-6. Adult-floxed and conditional skeletal muscle IL-6 knock out male and female mice were used to study energy expenditure (indirect calorimetry at rest and during treadmill exercise, and body temperature cycle during the light phase) and energy intake (response to fast/refeeding). We also evaluated the responses to leptin and the activity of the insulin signalling pathway in skeletal muscle and liver by phosphorylation of Akt at Ser 473...

Uridine, a pyrimidine nucleoside present at high levels in the plasma of rodents and humans, is critical for RNA synthesis, glycogen deposition, and many other essential cellular processes. It also contributes to systemic metabolism, but the underlying mechanisms remain unclear. We found that plasma uridine levels are regulated by fasting and refeeding in mice, rats, and humans. Fasting increases plasma uridine levels, and this increase relies largely on adipocytes. In contrast, refeeding reduces plasma uridine levels through biliary clearance...

BACKGROUND: Oral feeding intolerance (OFI) is a common complication in patients with acute pancreatitis (AP). Variations in blood glucose are associated with impaired gastrointestinal function but, to date, measures of glucose variability have not been investigated to predict OFI in patients with AP. AIM: To investigate the usefulness of several glucose variability measures in predicting the occurrence of OFI early in the course of AP. METHODS: In this prospective cohort study, six measures of glucose variability were calculated prior to the occurrence of OFI...

Central pontine myelinolysis (CPM) is a demyelinating disorder characterized by the loss of myelin in the center of the basis pons, and is mainly caused by the rapid correction of hyponatremia. We report the case of a young woman who presented with gait disturbance and alcohol withdrawal, and who was eventually diagnosed with CPM. Generally, the cause and pathogenesis of CPM in chronic alcoholics remain unclear. In this cases, the CPM may be unrelated to hyponatremia or its correction. However, it is possible that the osmotic pressure changes due to refeeding syndrome after alcohol withdrawal was the likely cause in this case...

CTRP9 is a member of the C1q/TNF-related protein (CTRP) superfamily and has been studied in mammals, while the comparative studies of CTRP9 in non-mammalian species are still absent. In this study, CTRP9 was isolated and characterized from the orange-spotted grouper (Epinephelus coioides). The full length cDNA of CTRP9 was 1378 bp in size with ORF (open reading frame) of 1020 bp which encods a 339 amino acids preprohormone. The mRNA expression of CTRP9 showed a rather high level in the kidney and brain, but low level in other tissues...

OBJECTIVE: Glucagon-like peptide-2 (GLP-2) is co-secreted with GLP-1 from gut endocrine cells, and both peptides act as growth factors to expand the surface area of the mucosal epithelium. Notably, GLP-2 also enhances glucose and lipid transport in enterocytes; however, its actions on control of amino acid (AA) transport remain unclear. Here we examined the mechanisms linking gain and loss of GLP-2 receptor (GLP-2R) signaling to control of intestinal amino acid absorption in mice. METHODS: Absorption, transport, and clearance of essential AAs, specifically lysine, were measured in vivo by Liquid Chromatography triple quadrupole Mass Spectrometry (LC-MS/MS) and ex vivo with Ussing chambers using intestinal preparations from Glp2r(+/+) and Glp2r(-/-) mice...

BACKGROUND: Medical stabilization through inpatient nutritional rehabilitation is often necessary for patients with eating disorders (EDs) but includes the inherent risk of refeeding syndrome. Here we describe our experience of implementing and sustaining an inpatient nutritional rehabilitation protocol designed to strategically prepare patients with EDs and their families for discharge to a home setting in an efficient and effective manner from a general adolescent medicine unit. We report outcomes at admission, discharge, and 4-weeks follow-up...

Reciprocal regulation of hepatic glycolysis and gluconeogenesis contributes to systemic metabolic homeostasis. Recent evidence from lower order organisms has found that reversible post-translational modification of glyceraldehyde-3-phosphate dehydrogenase (GAPDH), particularly acetylation, contributes to the reciprocal regulation of glycolysis/gluconeogenesis. However, whether this occurs in mammalian hepatocytes in vitro or in vivo is unknown. Several proteomics studies have identified 4 lysine residues in critical regions of mammalian GAPDH that are altered by multiple post-translational modifications...

INTRODUCTION: Re-feeding Syndrome (RS) is a deadly complication, which can be encountered during "refeeding" of malnourished patients. In these patients, thiamin deficiency may develop and "risk awareness" is the most significant factor in the management of these patients. In this case report, the treatment is presented of an elderly patient who was diagnosed with RS and followed-up in the intensive care unit (ICU) due to resistant fluidelectrolyte imbalance. CASE: An 87-year-old elderly woman was admitted to the hospital due to aspiration pneumonia...

OBJECTIVE: Refeeding syndrome occurs when reinstating nutrition to severely malnourished patients. It can sometimes be fatal, particularly as a result of cardiac involvement such as congestive heart failure and arrhythmias. The aim of this study was to report a case of cardiogenic shock that occurred during refeeding in a patient with anorexia nervosa (AN). The cardiogenic shock was due to a previously unrecognized mechanism, namely a transient left midventricular obstruction that completely disappeared after treatment...

OBJECTIVE: Weight loss maintenance following very-low-calorie meal plans is poorly studied. This report describes weight loss efficacy and predictors of weight loss maintenance of a ketogenic, very-low-calorie meal plan (protein-sparing modified fast, PSMF) in people with obesity. METHODS: 127 consecutive adults in the PSMF meal plan (27.2 ±19.5 weeks) and 48 adults on a conventional, hypocaloric meal plan (23.6 ±20.8 weeks) were retrospectively studied for percent weight change from baseline to end of intervention and at 6, 12, and 24 months post-intervention...
