Efficacy of Fenfluramine and Norfenfluramine Enantiomers and Various Antiepileptic Drugs in a Zebrafish Model of Dravet Syndrome.

Dravet syndrome (DS) is a rare genetic encephalopathy that is characterized by severe seizures and highly resistant to commonly used antiepileptic drugs (AEDs). In 2020, FDA has approved fenfluramine (FFA) for treatment of seizures associated with DS. However, the clinically used FFA is a racemic mixture (i.

Local immune response to food antigens drives meal-induced abdominal pain.

Up to 20% of people worldwide develop gastrointestinal symptoms following a meal, leading to decreased quality of life, substantial morbidity and high medical costs. Although the interest of both the scientific and lay communities in this issue has increased markedly in recent years, with the worldwide introduction of gluten-free and other diets, the underlying mechanisms of food-induced abdominal complaints remain largely unknown. Here we show that a bacterial infection and bacterial toxins can trigger an immune response that leads to the production of dietary-antigen-specific IgE antibodies in mice, which are limited to the intestine.

Development of a HILIC-MS/MS method for the quantification of histamine and its main metabolites in human urine samples.

An LC-MS/MS method was developed enabling the separation and quantification of histamine and its main metabolites (imidazole acetaldehyde, imidazole acetic acid, methyl imidazole acetic acid, methyl histamine, acetyl histamine) in urine samples. A fast separation was achieved in 10 min on two HILIC columns connected in series by adopting a linear gradient followed by an isocratic hold. The sample preparation consisted of a simple dilution step wherein 10 μL of urine was diluted with acetonitrile (ACN) to a final volume comprising 95% ACN.

Patient-centered care coordination, education and counseling of patients treated with oral anticancer drugs: An importance-performance analysis.

Purpose: To analyse the importance and performance of key elements in patient-centered care coordination, education and counseling of patients treated with oral anticancer drugs.

Method: In four Belgian non-academic hospitals, the importance and performance of a set of 82 key elements was cross-sectionally evaluated by primary and secondary healthcare professionals and by patients. These key elements were divided in 6 themes: coordination of care, style and content of patient contacts, medication counseling at treatment initiation, follow-up of treatment, psychosocial support, and involvement of family and friends.
