Antidepressants and the risk of hyponatremia: A multi‐institutional cohort study using observational medical outcomes partnership—Common Data Model

British Journal of Clinical Pharmacology, EarlyView.
Aim Hyponatremia is a common yet potentially serious adverse event associated with antidepressants. Identifying the antidepressant class with the least risk of hyponatremia would improve patient safety. Methods Using electronic medical records from 15 hospitals standardized into Observational Medical Outcomes Partnership Common Data Model (2003–2023 ...

Models for Cometary Comae Containing Negative Ions [PDF]

, 2012
The presence of negative ions (anions) in cometary comae is known from Giotto mass spectrometry of IP/Halley. The anions O(-), OH(-), C(-), CH(-) and CN(-) have been detected, as well as unidentified anions with masses 22-65 and 85-110 amu [I].

Use of antiemetics in early pregnancy 2012–2022: A cross‐sectional study

British Journal of Clinical Pharmacology, EarlyView.
Aim Nausea and vomiting in pregnancy impact quality of life, yet many pregnant women feel dismissed by healthcare professionals, despite the safety of first‐line antiemetic treatments for both mother and fetus. Therefore, this study aims to describe the prevalence of patient‐reported antiemetic use in early pregnancy in Copenhagen, Denmark, the changes

Feasibility and Safety of Distal Transradial Access in Patients With Out‐of‐Hospital Cardiac Arrest Undergoing Emergency PCI: A Single‐Center Retrospective Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Distal transradial access (dTRA) has gained attention for its lower risk of vascular complications compared to conventional transradial access (TRA). However, its feasibility and safety in patients with out‐of‐hospital cardiac arrest (OHCA) undergoing emergency percutaneous coronary intervention (PCI) remain uncertain.
