The effects of ketamine on symptoms of depression and anxiety in real-world care settings: A retrospective controlled analysis.

Introduction: Ketamine intravenous therapy (KIT) appears effective for treating depression in controlled trials testing a short series of infusions. A rapidly proliferating number of clinics offer KIT for depression and anxiety, using protocols without a strong evidence basis. Controlled comparison of mood and anxiety from real-world KIT clinics, and the stability of outcomes, is lacking.

Observational study to characterize treatment-resistant depression in Germany, France and the United Kingdom: analysis of real-world data collected through a survey of healthcare professionals.

Objective: This study describes treatment patterns, productivity, healthcare resource utilization and previous episodes of depression for patients with treatment-resistant depression (TRD).

Methods: In this cross-sectional study, a quantitative survey was administered to 225 healthcare providers (HCPs) distributed evenly across Germany, France and the UK from July to August 2021. Each HCP was asked to answer based on medical records of five patients with TRD, defined as patients failing to respond to two or more treatments of adequate dose and duration in the same episode of major depressive disorder (MDD), which provided a sample size of 1125 patients.

Critical review of methods for sampling, analysis, and monitoring of vapor-phase toluene diisocyanate.

This article is a critical review of some of the methods that have been used for the sampling, analysis, and monitoring of vapor-phase toluene diisocyanate (TDI). Only some of the methods that have received relatively widespread application have been addressed in this article. This review includes a "tutorial style" discussion of basic definitions and basic principles and procedures of quality control and metrology for sampling, analysis, and monitoring.

Application of the Shifting Method as a Technique to Correct for the Background in Quantitative Analysis by Open-Path FTIR.

In open-path Fourier Transform Infrared spectroscopy, the generation of a suitable background single-beam spectrum is of major concern. The Shifting Method is a derivative-like approach to correct for the background without the need to actually measure a background spectrum using the sample single-beam spectrum. A thorough study of the Shifting Method was conducted.

International Diffusion of Open Path FTIR Technology and Air Monitoring Methods: Taiwan (Republic of China).

International cooperation and diffusion of environmental technologies is a central goal of the U.S. EPA Environmental Technology Initiative, and is of great interest to many countries.
