This study uses data from nationwide Danish registries to assess breast cancer risk with continuous use of levonorgestrel-releasing intrauterine systems, accounting for other hormonal exposures.
A protective effect of childhood vaccinations on leukemia risk, particularly acute lymphoblastic (ALL), has been hypothesized, though findings are inconsistent. We used a nationwide cohort Danish children born 1997-2018 (n = 1,360,230), to examine associations between and (<20 years) using registry data (follow-up: December 31, 2018). Cox proportional hazard models with age as the underlying time estimated ratios (HRs) for (any, ALL, myeloid [AML], other), comparing vaccinated unvaccinated...
Is the risk of hospital admission or outpatient contact for mental disorders increased in children born to women with fertility problems compared without problems? We found an problems. Few studies have investigated after treatment and although some pointed risk, others no association. The inconsistent results may be due methodological constraints many previous studies, including small sample size short follow-up, resulting imprecise estimates lack information on patterns adulthood.

Large population-based studies are needed to examine the effect of maternal use fertility drugs on risk cancer in children, while taking into account underlying infertility. A cohort 123,322 children born Denmark between 1964 and 2006 68,255 women who had been evaluated for infertility was established. We used a case-cohort design calculated hazard ratios (HRs) childhood (0-19 years) young adulthood (20-29 associated with six groups (clomiphene, gonadotropins [i.e., human menopausal...
Background: Surveillance of childhood cancer incidence is informative for etiologic research and health policy. However, high-quality data covering several decades virtually complete diagnosis in children sparse.Methods: Incident cases (0–19 years at diagnosis), classified according to Birch Marsden's International Classification Childhood Cancer, first edition (ICCC-1), were identified the Danish Cancer Registry used calculate age-standardized rates (ASRs) estimated annual percentage change...

<h3>Importance</h3> The incidence of central nervous system (CNS) tumors in children appears to be increasing, yet few risk factors are established.
