Cardiovascular safety of dihydroergotamine mesylate delivered by precision olfactory delivery (INP104) for the acute treatment of migraine.

Objective: To report the cardiovascular (CV) safety of dihydroergotamine mesylate (DHE) administered by precision olfactory delivery (INP104) from two clinical trials.

Background: Although the absolute risk is low, migraine is associated with an increased risk of CV events. DHE is a highly effective acute treatment for migraine, but due to its theoretical risk of promoting arterial vasoconstriction, DHE is contraindicated in patients with CV disease or an unfavorable risk factor profile.

Vertical distribution and tissue selection of Helicoverpa zea (Lepidoptera: Noctuidae) adult oviposition and neonates on soybean with an indeterminate or determinate growth habit.

Helicoverpa zea (Boddie) is a polyphagous pest that can cause serious damage to crops, including soybeans (Glycine max L.). In soybeans with both determinate and indeterminate growth habits, H.

New characterization of dihydroergotamine receptor pharmacology in the context of migraine: utilization of a β-arrestin recruitment assay.

Introduction: Dihydroergotamine mesylate (DHE) is an established effective acute therapy for migraine and is often characterized by its broad receptor pharmacology. Knowledge of DHE pharmacology largely comes from studies employing older methodologies.

Objective: To assess DHE receptor activity using high-throughput methods to screen for functional ß-arrestin activity at G protein-coupled receptors (GPCRs).

The Gut-brain Connection and Episodic Migraine: an Update.

Purpose Of Review: Historical evidence suggests a shared underlying etiology for migraine and gastrointestinal (GI) disorders that involves the gut-brain axis. Here we provide narrative review of recent literature on the gut-brain connection and migraine to emphasize the importance of tailoring treatment plans for patients with episodic migraine who experience GI comorbidities and symptoms.

Recent Findings: Recent population-based studies report the prevalence of migraine and GI disorders as comorbidities as well as overlapping symptomology.

The Current Burden and Future Solutions for Preoperative Cataract-Refractive Evaluation Diagnostic Devices: A Modified Delphi Study.

Purpose: To obtain consensus on the key areas of burden associated with existing devices and to understand the requirements for a comprehensive next-generation diagnostic device to be able to solve current challenges and provide more accurate prediction of intraocular lens (IOL) power and presbyopia correction IOL success.

Patients And Methods: Thirteen expert refractive cataract surgeons including three steering committee (SC) members constituted the voting panel. Three rounds of voting included a Round 1 structured electronic questionnaire, Round 2 virtual face-to-face meeting, and Round 3 electronic questionnaire to obtain consensus on topics related to current limitations and future solutions for preoperative cataract-refractive diagnostic devices.
