While dried blood spot (DBS) analysis concerning low molecular mass molecules has become more and more established in various fields of analytical chemistry, the utility of DBS in determining peptides and proteins from DBS is yet comparably limited. In consideration of the fact that the apparent benefits of DBS sampling are similar for analytes of lower and higher molecular mass, dedicated (non-generic) sample preparation procedures are required that meet the needs for detecting peptidic drugs and hormones in DBS...

Background: The prevalence of diabetes mellitus (DM) is increasing worldwide. Thereby, an increasing rate of patients with DM are subjecting to spine surgery. Reviewing the literature, a higher rate of surgery-related complications is reported in DM patients. There is no prospective study comparing the outcomes of lumbar fusion surgery in patients with and without DM. We aimed to investigate whether DM is associated with worse patient-reported outcomes, lower fusion rate, and higher complication rate in subjects undergoing spinal lumbar fusion surgery...

Despite the abundance of plant-derived fats in our diet, their effects on appetite, and metabolic markers, remain unclear. This single-blinded 3-way cross-over pilot study aimed to investigate the ability of the two most abundant dietary plant-derived fats, oleic (OA) and linoleic (LA) acids, to modulate postprandial appetite and levels of circulating appetite and metabolic regulators in overweight/obese individuals. Meals were a high-carbohydrate control, a high-OA or a high-LA meal, and provided 30% of participants' estimated energy requirements...

The hepatic glucose fasting response is gaining traction as a therapeutic pathway to enhance hepatic and whole-host metabolism. However, the mechanisms underlying these metabolic effects remain unclear. Here, we demonstrate the epidermal-type lipoxygenase, eLOX3 (encoded by its gene, Aloxe3), is a potentially novel effector of the therapeutic fasting response. We show that Aloxe3 is activated during fasting, glucose withdrawal, or trehalose/trehalose analogue treatment. Hepatocyte-specific Aloxe3 expression reduced weight gain and hepatic steatosis in diet-induced and genetically obese (db/db) mouse models...

Insulin is a frequently prescribed drug in hospitals and is usually administered by syringe pumps with an extension line which can be made of various materials. Two insulin solutions were studied: an insulin analogue, Novorapid® which contains insulin aspart and two phenolic preservatives (e.g. phenol and metacresol) and Umuline rapide® with human insulin and metacresol as preservative. Some studies have indicated interactions between insulin, polyvinyl chloride (PVC) and polyethylene (PE). The aim of this work was to study such interactions between Novorapid® or Umuline rapide® and infusion extension line materials (PVC, PE and coextruded (PE/PVC))...

AIMS: Patients with type 2 diabetes and non-alcoholic fatty liver disease (NAFLD) exhibit considerable residual risk for cardiovascular disease (CVD). There is, therefore, increasing interest in targeting postprandial lipid metabolism and remnant cholesterol. Treatment with the glucagon-like peptide 1 (GLP-1) analogue liraglutide reduces CVD risk by mechanisms that remain unexplained in part. Here we investigated the effects of liraglutide intervention on ectopic fat depots, hepatic lipogenesis and fat oxidation, postprandial lipid metabolism and glycaemia in humans with type 2 diabetes...

Erzsébet Nagy, Gábor Kovács
INTRODUCTION: The effectiveness of human and analogue insulins is similar but the latter have more advantageous pharmacokinetic features, leading to an improvement in hypoglycaemia and come closer to achieving the physiologic insulin profile. AIM: To demonstrate that switching from a human basal-bolus insulin treatment to an insulin glargine-based basal-bolus regimen can achieve a better glycaemic control. METHOD: This 3-month prospective, non-interventional study, including a 12-month retrospective data collection phase, enrolled patients who were switched to the insulin glargine- - 100 U/mL - based basal-bolus treatment at the time of enrolment if they were inadequately controlled and had at least one additional HbA1c result in the 12 months before the switch...

OBJECTIVE: Subcutaneous (sc) administration of fast-acting insulin analogues is the key in conventional therapy of type 1 diabetes (T1D). A model of sc insulin absorption would be helpful for optimizing insulin therapy and test new open- and closed-loop treatment strategies in in silico platforms. Some models have been published in the literature, but none was assessed on a frequently-sampled large dataset of T1D subjects. The aim here is to propose a model of sc absorption of fast-acting insulin, which is able to describe the data and precisely estimate model parameters with a clear physiological interpretation...

Glucagon-Like Peptide-1 (GLP-1) is hydrolyzed by Dipeptidyl-Peptidase 4 (DPP4), and several studies suggest that both GLP-1 and DPP4 inhibitors have potentially beneficial effects on cardiovascular risks. The objective of this study was to analyze the differences between plasma GLP-1 and DPP4 activity in male and female patients with metabolic syndrome, and its relationship with physiological and metabolic parameters. The study included 25 apparently healthy Controls (C) and 21 Metabolic Syndrome patients (MS)...

Since the discovery of amylin its use has been discouraged by the inadequacy of the protocol involving multiple injections in addition to insulin. We aimed here to develop a combined fixed-dose formulation of pramlintide with fast-acting insulin. We have investigated the compatibility of regular and fast-acting insulin analogues (Aspart, AspB28 , and LisPro, LysB28 ProB29 ) with the amylin analogue pramlintide by using electrospray ionization - ion mobility spectrometry-mass spectrometry (ESI-IMS-MS), kinetic aggregation assays monitored by thioflavin T, and transmission electron microscopy (TEM) in the evaluation of the aggregation product...

The development of fast-acting and highly stable insulin analogues is challenging. Insulin undergoes structural transitions essential for binding and activation of the insulin receptor (IR), but these conformational changes can also affect insulin stability. Previously, we substituted the insulin A6-A11 cystine with a rigid, non-reducible C=C linkage ("dicarba" linkage). A cis -alkene permitted the conformational flexibility of the A-chain N-terminal helix necessary for high-affinity IR binding, resulting in surprisingly rapid activity in vivo Here, we show that, unlike the rapidly acting LysB28 ProB29 insulin analogue (KP insulin), cis -dicarba insulin is not inherently monomeric...
