Sulfamethoxazole-Trimethoprim-Induced Hyperkalemia in Hospitalized Patients Using Potassium-Sparing Drugs: An Observational Study.

The objective of this analysis is to investigate the risk of hyperkalemia in hospitalized patients using sulfamethoxazole-trimethoprim (Co-trimoxazole) and a potassium-sparing drug (potassium-sparing diuretic or renin-angiotensin system [RAS]-inhibitor). Researchers conducted a nested case control study within a cohort of hospitalized patients using a potassium-sparing diuretic and/or a RAS-inhibitor from the PHARMO Database Network. Researchers estimated the odds ratios (ORs) and 95% confidence intervals (CI) for the risk of hyperkalemia in patients receiving both Co-trimoxazole and a potassium-sparing drug compared with patients only receiving a potassium-sparing drug.

Hospital registration of adverse drug reactions in electronic health records: importance and contribution to pharmacovigilance.

Background: Information on registered adverse drug reactions (ADRs) in hospitals may provide a large real-world data source that can be used to ensure patients' safety. This study aimed to assess the potential contribution of hospital registration of ADRs in electronic health records (EHR) to pharmacovigilance.

Research Design And Methods: An observational retrospective descriptive study using data from the Jeroen Bosch Hospital in the Netherlands in 2019.

Capillary blood sampling for the determination of clozapine concentrations: analytical validation and patient experience.

Patients may be reluctant to start clozapine (CLZ) because of the frequent blood sampling needed for white blood cell monitoring, but also therapeutic drug monitoring of CLZ. Finger prick, instead of venepuncture, might lower the threshold to CLZ use. The aim of this study was to determine whether CLZ concentrations are the same in capillary and venous blood samples.

[John McCrae, physician and poet of "In Flanders Fields"].

During the Second Battle at Ypres (1915), the Canadian medical officer John McCrae was situated in an Advanced Dressing Station in Boezinge, Belgium. Heavily influenced by the suffering of the war he wrote the poem "In Flanders Fields" in May 1915. In this poem he writes about the fallen soldiers who will not rest, until others have taken over the torch of the battle.

[Serotin syndrome; literature overview and Lareb pharmacovigilance reports].

Serotonin syndrome is a medication-induced clinical syndrome, caused by an increased concentration of serotonin in the central and peripheral nervous system. An excess of serotonin can be caused by the use of one or more serotinergic substances on the one hand, or by decreased clearance of these substances on the other hand We carried out a systematic literature search to make an estimation of substances and patient-related factors that might be associated with an increased risk of serotonin syndrome. We also carried out a search for all reports of serotonin syndrome in the Lareb (Netherlands pharmacovigilance centre) database.
