Does endometriosis affect professional life? A matched case-control study in Switzerland, Germany and Austria.

OBJECTIVES Endometriosis is a gynaecological disease most commonly causing severe and chronic pelvic pain as well as an impaired quality of life. The aim of this study was to investigate if and how endometriosis affects choices regarding professional life as well as the quality of daily working life. DESIGN, SETTING AND PARTICIPANTS In the context of a multicentre case-control study, we collected data from 505 women with surgically/histologically confirmed diagnosis of endometriosis and 505 matched controls. Study participants were recruited prospectively in hospitals and doctors' practices in Switzerland, Germany and Austria. Using a detailed questionnaire, the study investigated work-life and career choices of study participants. MAIN OUTCOME MEASURES Associations between endometriosis/disease symptoms and limitations in career development as well as ability to work. RESULTS Women with endometriosis were less often able to work in their desired profession than women from the control group (adjusted OR=1.84, 95% CI: 1.15 to 2.94, R2=0.029, p=0.001) and they had to take health-related limitations into consideration in their career decisions to a significantly higher degree than women in the control group (OR=4.79, 95% CI: 2.30 to 9.96, R2=0.063, p<0.001). Among women with endometriosis, chronic pain was significantly associated with increased sick leave (OR=3.52, 95% CI: 2.02 to 6.13, R2=0.072, p<0.001) as well as with loss of productivity at work (OR=3.08, 95% CI: 2.11 to 4.50, R2=0.087, p<0.001). CONCLUSIONS Endometriosis is associated with impairment of professional life, in particular with regard to career choices. Further research to develop strategies to support endometriosis-affected women in realising professional opportunities is recommended. TRIAL REGISTRATION NUMBER NCT02511626; Pre-results

A highly contiguous genome assembly reveals sources of genomic novelty in the symbiotic fungus Rhizophagus irregularis

Funder: Max Planck Society; DOI: https://doi.org/10.13039/501100004189The root systems of most plant species are aided by the soil-foraging capacities of symbiotic arbuscular mycorrhizal (AM) fungi of the Glomeromycotina subphylum. Despite recent advances in our knowledge of the ecology and molecular biology of this mutualistic symbiosis, our understanding of the AM fungi genome biology is just emerging. Presented here is a close to T2T genome assembly of the model AM fungus Rhizophagus irregularis DAOM197198, achieved through Nanopore long-read DNA sequencing and Hi-C data. This haploid genome assembly of R. irregularis, alongside short- and long-read RNA-Sequencing data, was used to produce a comprehensive annotation catalog of gene models, repetitive elements, small RNA loci, and DNA cytosine methylome. A phylostratigraphic gene age inference framework revealed that the birth of genes associated with nutrient transporter activity and transmembrane ion transport systems predates the emergence of Glomeromycotina. While nutrient cycling in AM fungi relies on genes that existed in ancestor lineages, a burst of Glomeromycotina-restricted genetic innovation is also detected. Analysis of the chromosomal distribution of genetic and epigenetic features highlights evolutionarily young genomic regions that produce abundant small RNAs, suggesting active RNA-based monitoring of genetic sequences surrounding recently evolved genes. This chromosome-scale view of the genome of an AM fungus genome reveals previously unexplored sources of genomic novelty in an organism evolving under an obligate symbiotic life cycle
