Admission sodium levels and hospital outcomes.

Background: Previous studies have found an increase in mortality among patients with worsening degrees of hyponatraemia. There is limited evidence on the impact of dysnatraemia on outcomes such as length of stay (LOS) and intensive care unit (ICU) admission.

Aims: To investigate the relationship between admission sodium levels at a quaternary referral hospital and outcomes, including mortality, LOS and admission to ICU.

Diabetes Medications and Cardiovascular Outcomes in Type 2 Diabetes.

Introduction: Patients with type 2 diabetes have an increased risk of developing adverse cardiovascular (CV) outcomes. The evidence relating to the effects of glucose-lowering medications on CV outcomes is of variable quality and there are numerous trials ongoing.

Results: In this review, we summarise the available literature on CV outcomes of the following diabetes treatments: metformin, the sulfonylureas, acarbose, glucagon-like peptide 1 (GLP1) receptor agonists, dipeptidyl peptidase-4 inhibitors (DPP4i), sodium-glucose co-transporter 2 inhibitors (SGLT2i), thiazolidinediones (TZDs) and insulin.

Prognostic implications of left atrial volume index in patients in sinus rhythm.

The maximum left atrial volume index (LAVI) has been shown to be of prognostic values, but previous studies have largely been limited to older patients with specific cardiovascular conditions. We examined the independent prognostic values of LAVI in a large unselected series of predominantly younger patients in sinus rhythm followed up for a long period. We evaluated 483 consecutive patients (mean age 47.

Eleven amino acid glucagon-like peptide-1 receptor agonists with antidiabetic activity.

Glucagon-like peptide 1 (GLP-1) is a 30 or 31 amino acid peptide hormone that contributes to the physiological regulation of glucose homeostasis and food intake. Herein, we report the discovery of a novel class of 11 amino acid GLP-1 receptor agonists. These peptides consist of a structurally optimized 9-mer, which is closely related to the N-terminal 9 amino acids of GLP-1, linked to a substituted C-terminal biphenylalanine (BIP) dipeptide.

Echocardiographic evaluation of left atrial size and function: current understanding, pathophysiologic correlates, and prognostic implications.

Left atrial (LA) volume has recently been identified as a potential biomarker for cardiac and cerebrovascular disease. However, evidence regarding the prognostic implications of LA volume still remains unclear. Evaluation of LA size and function using traditional and more recent echocardiographic parameters is potentially feasible in the routine clinical setting.

Pulmonary delivery of a GLP-1 receptor agonist, BMS-686117.

Alternate delivery route of therapeutic peptides is an attractive non-invasive option to patients who must chronically self-administer their medication through injections. In recent years, much attention has centered on pulmonary peptide delivery of peptide drugs such as insulin and GLP-1 mimetic peptides in the treatment of type II diabetes. In this study, we assessed the feasibility of delivering BMS-686117, an 11-mer GLP-1 receptor peptide agonist, to the lung in rats via intratracheal administration.

Disconnection between the early onset anorectic effects by C75 and hypothalamic fatty acid synthase inhibition in rodents.

In order to explore the relationship between the anorectic effect of 3-carboxy-4-octyl-2-methylenebutyrolactone (C75) and its pharmacokinetic properties, studies of in vivo and in vitro pharmacological characterization of C75 were performed in Fischer rats. In a quantitative measurement of food intake, we determined that appetite suppression by C75 takes place within 4 h. The C(max) for C75 of 2.

Development and validation of a liquid chromatography-mass spectrometric method for the determination of DPC 423, an antithrombotic agent, in rat and dog plasma.

A sensitive and selective LC-MS-MS method for the determination of DPC 423 (I), an antithrombotic agent, is described. This method used a solid-phase extraction from 0.1 ml plasma with an Isolute C(2) cartridge.

High-speed gradient parallel liquid chromatography/tandem mass spectrometry with fully automated sample preparation for bioanalysis: 30 seconds per sample from plasma.

In this work, a high-throughput and high-performance bioanalytical system is described that is capable of extracting and analyzing 1152 plasma samples within 10 hours. A Zymark track robot system interfaced with a Tecan Genesis liquid handler was used for simultaneous solid-phase extraction of four 96-well plates in a fully automated fashion. The extracted plasma samples were injected onto four parallel monolithic columns for separation via a four-injector autosampler.
