The need for novel biological drugs against respiratory diseases has been highlighted during the Coronavirus (COVID-19) pandemic. The use of inhalation presents challenges to drug product stability, which is especially true for delivery using nebulizers (jet versus mesh technologies). The late-stage process of drug development in the pharmaceutical industry requires the investigation of in-use stability. In-use studies generate data that are guided by the requirements of regulatory authorities for inclusion in the clinical trial application dossier. In this review, I introduce the initial aspects of in-use stability studies during the development of an aerosol formulation to deliver biologics with a nebulizer. Lessons learned from this experience can guide future development and planning for formulation, analytics, material compatibility, nebulization process, and clinical trial preparations.

The clinical significance and burden of thyroid nodules discovered incidentally.
Ir J Med Sci
December 2024
School of Medicine, University College of Cork, Cork, Ireland.
Background: The majority of thyroid nodules are benign; however current guidelines suggest that thyroid incidentalomas should be appropriately evaluated to rule out malignancy.
Aims: This study aims to determine the incidence of thyroid incidentalomas and the likelihood that they harbour sinister pathology in the largest Irish cohort studied to-date.
Methods: A retrospective observational chart review was conducted using data from July 2018 to December 2018 using the Radiology Database in use at Cork University Hospital.
Desktop 3D printers in the workplace: use, emissions, controls, and health.
Ann Work Expo Health
December 2024
HSE Science Division, Health and Safety Executive's Science and Research Centre, Harpur Hill, Buxton SK17 9JN, United Kingdom.
Desktop three-dimensional (3D) printers are used in businesses, schools, and colleges, and are generally of an unenclosed design which may give rise to injuries or inhalation exposure to emissions of small particles (<1 µm) and volatile organic compounds (VOCs). The aim of this work was to explore the health risks related to the use of desktop 3D printers in workplaces in the United Kingdom. A digital survey on the use of desktop 3D printers was completed voluntarily and anonymously between February and June 2023, receiving 146 responses.

Such changes might be aided by voice-activated personal assistants (VAPAs), which offer interactive and real-time assistance through features such as reminders, or obtaining health information. However, there are little data on interest and acceptability of integrating VAPAs into programs such as the National Diabetes Prevention Program (National DPP) or diabetes, self-management, education, and support (DSMES) services.

Sci Rep
December 2024
Embryotox Center of Clinical Teratology and Drug Safety in Pregnancy, Institute of Clinical Pharmacology and Toxicology, Charité - Universitätsmedizin Berlin, corporate member of Freie Universität Berlin, Humboldt-Universität zu Berlin, Berlin, Germany.
Because of their developmental toxicity, some antiseizure medication (ASM) should be avoided during pregnancy. This may lead to discontinuation or switching of ASM after recognition of pregnancy, but some of these changes may be suboptimal. Trends in ASM use at conception were analyzed in 3,763 pregnancies prospectively ascertained by a teratology information service in Germany between 2000 and 2018.

Antimicrob Resist Infect Control
December 2024
Department of Microbiology, Immunology and Transplantation, KU Leuven, Louvain, Belgium.
Background: As part of the containment of the COVID-19 pandemic, mobile handwashing stations (mHWS) were deployed in healthcare facilities in low-resource settings. We assessed mHWS in hospitals in the Democratic Republic of the Congo for contamination with Gram-negative bacteria.
Methods: Water and soap samples of in-use mHWS in hospitals in Kinshasa and Lubumbashi were quantitatively cultured for Gram-negative bacteria which were tested for antibiotic susceptibility.
