The concepts, importance, and implications of bioanalytical method validation has been discussed and debated for a long time. The recent high profile issues related to bioanalytical method validation at both Cetero Houston and former MDS Canada has brought this topic back in the limelight. Hence, a symposium on bioanalytical method validation with the aim of revisiting the building blocks as well as discussing the challenges and implications on the bioanalysis of both small molecules and macromolecules was featured at the PITTCON 2013 Conference and Expo. This symposium was cosponsored by the American Chemical Society (ACS)-Division of Analytical Chemistry and Analysis and Pharmaceutical Quality (APQ) Section of the American Association of Pharmaceutical Scientists (AAPS) and featured leading speakers from the Food & Drug Administration (FDA), academia, and industry. In this symposium, the speakers shared several unique examples, and this session also provided a platform to discuss the need for continuous vigilance of the bioanalytical methods during drug discovery and development. The purpose of this article is to provide a concise report on the materials that were presented.

Introduction: Understanding chronic stress as a potential risk factor for COVID-19 progression could inform public health measures and personalized preventive interventions. Therefore, we investigated the influence of chronic stress prior to SARS-CoV-2 infection on symptom persistence 1 month after COVID-19 onset.
Methods: The participants of this prospective cohort study named "StressLoC" were adults with COVID-19 who had tested positive for SARS-CoV-2 infection within the last 7 days.

Purpose: Non-adherence to inhaled medication poses a significant clinical and economic burden on patients with respiratory diseases. This narrative review provides an overview of key aspects of hair analysis, in general and specific for inhaled medications, and explores the potential of hair analysis as a novel tool to monitor adherence to inhaled medications.
Methods: PubMed searches were conducted to explore four aspects: (1) mechanisms of (inhaled) drug's systemic absorption and deposition in hair; (2) quantification of drugs in hair; (3) factors impacting (inhaled) drug hair concentrations; and (4) clinical studies assessing inhaled medication adherence through hair analysis.

The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use M10 guideline provides a global framework for bioanalytical method validation in studies intended for regulatory submission. While its structure ensures consistency and data reliability, the guideline also acknowledges that not all studies require the same level of validation. This paper examines where full compliance is essential and where scientific judgment allows for leaner, context-driven validation, such as in early-stage development, for additional matrices, metabolites, nonstandard biological matrices or studies intended for internal decision-making.

Background: Determination of the estradiol hormone in urine is crucial for evaluating congenital adrenal hyperplasia, certain hormone-producing ovarian tumors, polycystic ovary syndrome, liver disease, pregnancy, and infertility. On the other hand, steroid hormones can have destructive effects on the environment, animals, and the endocrine system of humans. Consequently, accurately measuring this hormone's concentration in trace amounts is essential for environmental safety and human health.
