Assessing and addressing barriers towards MDI use in acute asthma exacerbations at a tertiary pediatric ED in the United Arab Emirates.

Asthma is one of the most common causes of emergency department (ED) visits in children. Therapy delivered through a meter dose inhaler with spacer (MDI + S) is equally as effective as nebulization in mild and moderate asthma exacerbations but was not routinely prescribed in the ED at the largest tertiary center for pediatrics in the United Arab Emirates (UAE). Phase 1 of this cohort study involved a validated survey to evaluate physicians' knowledge, attitudes and perceptions towards MDI therapy.

Potential for Gut Peptide-Based Therapy in Postprandial Hypotension.

Postprandial hypotension (PPH) is an important and under-recognised disorder resulting from inadequate compensatory cardiovascular responses to meal-induced splanchnic blood pooling. Current approaches to management are suboptimal. Recent studies have established that the cardiovascular response to a meal is modulated profoundly by gastrointestinal factors, including the type and caloric content of ingested meals, rate of gastric emptying, and small intestinal transit and absorption of nutrients.

Gastrointestinal Mechanisms Underlying the Cardiovascular Effect of Metformin.

Metformin, the most widely prescribed drug therapy for type 2 diabetes, has pleiotropic benefits, in addition to its capacity to lower elevated blood glucose levels, including mitigation of cardiovascular risk. The mechanisms underlying the latter remain unclear. Mechanistic studies have, hitherto, focused on the direct effects of metformin on the heart and vasculature.

Metformin attenuates the postprandial fall in blood pressure in type 2 diabetes.

Metformin has been shown to modulate the cardiovascular response to intraduodenal glucose in patients with type 2 diabetes (T2DM), and may have the capacity to regulate postprandial blood pressure (BP), which is often inadequately compensated in T2DM, resulting in postprandial hypotension. In the present study, we evaluated the acute effects of metformin on the BP and heart rate (HR) responses to oral glucose in patients with T2DM. Ten diet-controlled T2DM patients were evaluated on two occasions in a double-blind, randomized, crossover design.

Comparative effects of proximal and distal small intestinal administration of metformin on plasma glucose and glucagon-like peptide-1, and gastric emptying after oral glucose, in type 2 diabetes.

Aims: The gastrointestinal tract, particularly the lower gut, may be key to the anti-diabetic action of metformin. We evaluated whether administration of metformin into the distal, vs the proximal, small intestine would be more effective in lowering plasma glucose by stimulating glucagon-like pepetide-1 (GLP-1) and/or slowing gastric emptying (GE) in type 2 diabetes (T2DM).

Materials And Methods: Ten diet-controlled T2DM patients were studied on three occasions.

Agricultural irrigation of vine crops from desalinated and brackish groundwater under an economic perspective. A case study in Siġġiewi, Malta.

Maltese agriculture faces great challenges due to the severe scarcity of water. Sufficient water resources, in quantity and quality, are necessary to cover the demand in the production of wine grape, one of the most important crops in Maltese agriculture. But also, economic efficiency is essential in the grape cultivation.

A Protein Preload Enhances the Glucose-Lowering Efficacy of Vildagliptin in Type 2 Diabetes.

Objective: Nutrient "preloads" given before meals can attenuate postprandial glycemic excursions, at least partly by slowing gastric emptying and stimulating secretion of the incretins (i.e., glucagon-like peptide-1 [GLP-1] and glucose-dependent insulinotropic polypeptide [GIP]).
