Stamatìa Tsampà has joined CPE as a doctoral student in perinatal pharmacoepidemiology under the main supervision of Cathrine Axfors. Stamatìa is a medical doctor and holds a master’s degree in Public Health Sciences, KI. During her thesis, she was working on discovering trends and patterns in medication use during pregnancy based on the Swedish registers and is joining CPE to contribute on systematic exploration of pregnancy drug safety using tree-based scan statistics.

Cathrine Axfors recently joined CPE as an Assistant Professor. Cathrine is a medical doctor with a PhD in perinatal psychiatry at Uppsala University, and she just came back to Sweden after two international postdocs in meta-research/evidence synthesis. Her previous research covers perinatal epidemiology, clinical trial transparency, and evidence synthesis for COVID-19. At CPE, Cathrine will start up a new project on systematic exploration of pregnancy drug safety in Swedish registers using tree-based scan statistics. 

At this year’s conference of the European Psychiatric Association in Madrid, Josef Isung presented findings from our ongoing study on sexual dysfunction in depression. The results show that the incidence of sexual dysfunction, including cases treated pharmacologically, is highest in the first year following a depression diagnosis and increases with age.

Essi Whaites Heinonen is new postdoc at CPE who will be working with Carolyn Cesta at 50% combined with clinical work as a neonatologist at Karolinska University Hospital. With her planned studies at CPE, Essi aims to create a neonatology-arm within the group, focusing on the neonatal effects after maternal use of medications during pregnancy.

Awad Smew is new postdoc at CPE who will be working with Carolyn Cesta. His main interest lies in optimising safety of maternal care through pharmacoepidemiologic studies of drug use during pregnancy as well as understanding effects of the pregnant women exposed to surgery, anaesthesia, or intensive care. 

This relates to Awad´s clinical work as a physician in anaesthesia and intensive care medicine at Karolinska University Hospital Solna. 

Asina is a public health master's student from Lunds University. This last semester of her master studies, Asina wants to specialize in the field of epidemiology as this is the area of public health she is most passionate about. She will be supervised by Marie Linder and David Hägg during her thesis work, were she will investigate the association between malignant melanoma and atopic dermatitis. Asina completed her undergraduate degree in the field of biological sciences, with a major in genetics.

Ingunn is a master’s student in Mathematical Statistics at Stockholm University. She will be writing her master’s thesis under the supervision of Pär Karlsson and Marie Linder, focusing on causal survival analysis. She completed her BSc in Applied Mathematics, majoring in statistics and data science in Reykjavík, Iceland.

In memory of Helle Kieler, former CPE director who passed away last fall, an In Memoriam has been written and published in the journal “Pharmacoepidemiology and Drug Safety”.

Julia Eriksson joined CPE as a statistician in June 2023 and will start her next chapter as a PhD student in January under the supervision of Marie Linder and other CPE/KEP researchers. Her project will investigate the exposure of glucagon-like peptide-1 (GLP-1) analogues in Sweden, focusing on use, indication, safety and efficacy. Julia has a Master's degree in Mathematical Statistics from Stockholm University and has worked as a statistician at Karolinska Institutet since 2021. 

CPE’s assistant professor Carolyn Cesta and affiliated researcher Cathrine Axfors have received a total of 17 million Swedish kronor in funding from individual starting grants from the Swedish Research Council (VR) and a project grant from the Swedish Research Council for Health, Working Life and Welfare (FORTE). The funding will be used for projects investigating the safety of medication use in pregnancy using Swedish national register data in collaboration with Nordic and international collaborators. 

We are happy to inform that CPE will arrange a course in pharmacoepidemiology 17-21 February 2025, “Drug exposure Definitions and Study Design Approaches in Register-based data”.

The application period for the course is from 15 October to 5 November. https://doctoralcourses.application.ki.se/fubasextern/info?kurs=K2F6033

Helle Kieler, professor emeritus and former centre director Helle Kieler , passed away 1 September at the age of 68.
