Clinical Features and Hormonal Profile of Macroprolactinomas Presenting With the Hook Effect: A Systematic Review.

Objective: An assay artifact known as the "hook effect" causes spuriously low serum prolactin levels. This systematic review aimed to examine clinical reports on the "hook effect" in patients with macroprolactinomas to describe associated clinical features.

Methods: We systematically searched multiple databases from database inception to April 16, 2024 for case reports, case series, or observational studies of macroprolactinomas presenting with the hook effect.

Interrater agreement and reliability of the Bosniak classification for cystic renal masses version 2019.

Background: The Bosniak classification for cystic renal masses has undergone refinements since its inception. The 2019 version provides more objective criteria to enhance interrater agreement but needs validation. This study compares the interrater agreement of the 2005 and 2019 Bosniak classifications for cystic renal masses.

Initial behaviors and attitudes towards the COVID-19 vaccine in sarcoidosis patients: results of a self-reporting questionnaire.

Background: Individuals with self-declared sarcoidosis are at increased risk of COVID-19 related morbidity and mortality for which vaccination can be lifesaving. Despite this, vaccine hesitancy remains a large barrier to global acceptance of vaccination against COVID-19. We aimed to identify individuals with sarcoidosis who had and had not been vaccinated against COVID-19 vaccine to 1) establish a safety profile of COVID-19 vaccination in those with sarcoidosis and 2) to elucidate factors that contribute to COVID-19 vaccine hesitancy.
