Summary
Vagus nerve stimulation (VNS) management varies significantly among healthcare providers, impacting patient outcomes. Further training on VNS programming, especially the Scheduled Programming feature, can improve consistency.
Area of Science:
- Neurology
- Neurosurgery
- Medical Devices
Background:
- Vagus nerve stimulation (VNS) is a key neuromodulation therapy for drug-resistant epilepsy not amenable to surgery.
- Established for 30 years, VNS has diverse clinical practice patterns among healthcare providers (HCPs).
Purpose of the Study:
- To investigate the variability in VNS titration and dosing practices among HCPs.
- To explore the relationship between VNS management strategies and patient outcomes using CORE-VNS study data.
Main Methods:
- A global survey of HCPs regarding VNS dosing and titration habits.
- Analysis of patient data from the CORE-VNS Study, examining generator model usage and programming features.
Main Results:
- Significant global variability observed in VNS initial/maximum target doses and time-to-dose among providers.
- Users of the SenTiva generator with Scheduled Programming showed faster time-to-dose compared to earlier models.
- Varied programming approaches correlated with differing perceptions of time to clinical benefit.
Conclusions:
- Discrepancies in VNS management highlight the need for standardized training.
- Optimizing VNS therapy may be enhanced through consistent application of programming features like Scheduled Programming.
- Further education for HCPs on VNS use can lead to more uniform patient care and potentially improved outcomes.

01:23EDTA: Indirect and Alkalimetric Titration
816
Unlike direct titration, back-titration, and displacement titration, indirect titration is an EDTA titration method for quantifying anions. In the indirect titration method, anions are precipitated as their insoluble salts with excess metal ions. The filtrate containing the excess metal ions is directly titrated with standard EDTA until the endpoint is achieved. Another approach involves extracting the metal ion and back-titrating with standard EDTA to obtain the endpoint. In this way, the...

01:08Titrimetric Methods: Types and Commonly Used Strategies
860
In chemistry, titrimetric methods are broadly classified into three types: volumetric, gravimetric, and coulometric. Volumetric titrations involve measuring the volume of a titrant of known concentration that is required to react completely with an analyte. In gravimetric titrations, the standard solution reacts with the analyte to form an insoluble precipitate, which is filtered, dried, and weighed. In coulometric titrations, current is applied to an electrochemical reaction until the reaction...

01:16Titration in Nonaqueous Solvents
721
Most acid-base titrations are performed in an aqueous medium. In aqueous titrations, water competes with weaker acids or bases for proton donation or acceptance, leading to ambiguous endpoints in the titration curve. Water also affects the partial ionization of weak acids or bases. For example, water accepts a proton from acetic acid to form hydronium and acetate ions. The hydronium ion formed is a stronger acid than acetic acid, and the acetate ion is a stronger base than water. As a result,...

01:30EDTA: Direct, Back-, and Displacement Titration
2.4K
The EDTA titration types for metal ion analysis include direct titration, back-titration, and replacement titration.
Direct titration involves buffering the metal ion solution to the desired pH and directly titrating with standard EDTA until the endpoint. The optimum pH ensures a large conditional formation constant of metal−EDTA and visibility of the free indicator color in the solution. In addition, auxiliary complexing reagents are used to prevent the precipitation of metal hydroxides...

01:26Acid–Base Titration: Overview
9.0K
An acid-base titration is a technique used to determine the concentration of an unknown acid or base, using a titrant of known concentration–either a base for acid titration or an acid for base titration. The process involves gradually adding the titrant, leading to a predictable change in the pH of the solution. This change is plotted on a titration curve, showing how a solution's pH varies with the amount of titrant added. Such curves are instrumental in monitoring the...
