In the primary analysis report of GAIA/CLL13 trial, we found that venetoclax-obinutuzumab and venetoclax-obinutuzumab-ibrutinib improved undetectable measurable residual disease (MRD) rates progression-free survival compared with chemoimmunotherapy in patients previously untreated chronic lymphocytic leukaemia. However, to our knowledge, no data on direct comparisons different venetoclax-based combinations are available.

Questionnaire-based zygosity assessment in twins has generally been found to be valid. In this report we evaluate sex- and age-differences the validity of such questionnairebased classification when using four questions that have basis The Danish Twin Registry for half a century. Three hundred forty-two male 531 female twin pairs were diagnosed genetic markers results compared with original questionnaire based classification. We significant differences accuracy diagnosis stratifying data sex...

Abstract Physical functioning late in life has been shown to be affected by genetic factors. Only a few variants have suggested associated with physical functioning, and this only selected populations (e.g., young healthy males elite athletes). Declining is major problem terms of prevalence, morbidity, functional limitations, quality life. It therefore interest find phenotype reflecting which relatively high heritability can measured large samples. Hand grip strength known muscular other...

However, long‐term estimates as well cause‐specific data are sparse.

It is well established that the male sex associated with increased risk for, as poorer survival of, most cancers. A similar pattern has been described in lymphomas but not yet comprehensively assessed. In this nationwide population-based cohort study, we used Swedish Lymphoma Register to investigate differences lymphoma subtype incidence and excess mortality adults (age 18-99) diagnosed 2000-2019. Male-to-female rate ratios (IRRs) (EMRs) adjusted for age calendar year were predicted using...

In patients with systemic mastocytosis (SM), several aspects of morbidity remain poorly understood. We assessed the risk solid cancers, cardiovascular disease, anaphylaxis, osteoporosis, and fractures in SM patients. Using Danish medical registries, we conducted a nationwide population-based cohort study including 687 adult (≥15 years) diagnosed during 1997-2012.

This nationwide retrospective study linked health registries to identify 242 patients in Denmark 1977‐2017. For comparison, we identified three age‐matched sex‐matched cohorts only a general population cohort. The cohort had mean age 58.5 years at diagnosis, 51.2% were women, 27.3% classified as...
