Prevalence of drugs used for chronic conditions after diagnosis of thyroid cancer: a register-based cohort study.

Objective: Little is known about thyroid cancer survivors' risk of chronic conditions. We, therefore, investigated the prevalence of drugs used for chronic conditions among thyroid cancer patients using population-wide register data.

Methods: We linked data from the Cancer Registry of Norway to the Norwegian Prescription Database and other databases for a study population of 3.

Incidence trends of adult glioma in Norway and its association with occupation and education: A registry-based cohort study.

Background: Gliomas constitute 75 % of all malignant primary adult brain tumors. Being the most frequent histologic subtype, glioblastomas (GBMs) cause substantial morbidity and mortality worldwide and the Nordic countries have some of the highest incidence rates in the world. Therefore, we investigated the incidence of gliomas in Norway including time trends and associations with education and occupation.

Associations between pregnancy-related factors and birth characteristics with risk of rare uterine cancer subtypes: a Nordic population-based case-control study.

Purpose: Uterine sarcomas are a rare group of uterine malignancies. Due to the low incidence and changes in uterine sarcoma classification, risk factors are not well characterized. Our objective was to evaluate risk factors for uterine sarcoma and compare risk factors between uterine sarcoma, malignant mixed Mullerian tumors (MMMTs), and type I endometrial carcinomas.

Body mass index, triglyceride-glucose index, and prostate cancer death: a mediation analysis in eight European cohorts.

Background: Insulin resistance is a hypothesised biological mechanism linking obesity with prostate cancer (PCa) death. Data in support of this hypothesis is limited.

Methods: We included 259,884 men from eight European cohorts, with 11,760 incident PCa's and 1784 PCa deaths during follow-up.

ADHD medication discontinuation and persistence across the lifespan: a retrospective observational study using population-based databases.

Background: Although often intended for long-term treatment, discontinuation of medication for ADHD is common. However, cross-national estimates of discontinuation are missing due to the absence of standardised measures. The aim of this study was to determine the rate of ADHD treatment discontinuation across the lifespan and to describe similarities and differences across countries to guide clinical practice.
