How do patients determine when their inhaler is empty? Insights from an analysis of returned inhalers and a patient survey.

Background: Inhalers are widely used for the management of asthma and chronic obstructive pulmonary disease. However, there is little knowledge about the extent to which an inhaler is used and when it is disposed of, despite the implications for an individual's health (when used beyond the recommended number of doses (overused)), and medicine wastage, healthcare costs and the environment (when discarded with remaining doses (underused)). To explore inhaler use, we assessed the number of doses remaining in pressurised metered-dose inhalers (pMDIs) returned via a Chiesi Inhaler Recycling scheme.

Differential cortical aspartate uptake across the oestrous cycle is associated with changes in gut microbiota in Wistar-Kyoto rats.

Pain and psychological stress are intricately linked, with sex differences evident in disorders associated with both systems. Glutamatergic signalling in the central nervous system is influenced by gonadal hormones via the hypothalamic-pituitary-adrenal axis and is central in pain research. Emerging evidence supports an important role for the gut microbiota in influencing pain signalling.

GP emigration from Ireland: an analysis of data from key destination countries.

Background: Ireland is experiencing a general practitioner (GP) workforce crisis, facing an ageing workforce, a growing population with increased life expectancy, and increased complexity of patients. The GP crisis threatens access to primary care in Ireland, as well as Ireland's aim to transform into a primary-care centred system of universal healthcare via the proposed "Sláintecare" healthcare reforms. The challenges faced are common to many countries as health systems seek to expand their medical workforce post-pandemic.

Recommendations for the optimization of student led free vision screening programs.

Purpose: To report the summary characteristics of operational models associated with Student Led Free Vision Screening Programs (SLFVSP) and to identify opportunities for program optimization.

Methods: An 81-question mixed methods survey was distributed to SLFVSP leaders nationwide and Medical Student Educators within the American University Ophthalmology Professors (AUPO) Association. Survey responses were analyzed using Mann Whitney U and Fisher's Exact tests.

Novel Dynamic Organ Storage System Enhances Liver Graft Function in a Porcine Donation After Circulatory Death Model.

Donation after circulatory death (DCD) livers face increased risks of critical complications when preserved with static cold storage (SCS). Although machine perfusion (MP) may mitigate these risks, its cost and logistical complexity limit widespread application. We developed the Dynamic Organ Storage System (DOSS), which delivers oxygenated perfusate at 10°C with minimal electrical power requirement and allows real-time effluent sampling in a portable cooler.
