- Antimicrobial resistance (AMR) is a major threat to global health. Understanding the emergence, evolution, and transmission of individual antibiotic resistance genes (ARGs) is essential to develop sustainable strategies combatting this threat. Here, we use metagenomic sequencing to analyse ARGs in 757 sewage samples from 243 cities in 101 countries, collected from 2016 to 2019. We find regional patterns in resistomes, and these differ between subsets corresponding to drug classes and are partly driven by taxonomic variation. The genetic environments of 49 common ARGs are highly diverse, with most common ARGs carried by multiple distinct genomic contexts globally and sometimes on plasmids. Analysis of flanking sequence revealed ARG-specific patterns of dispersal limitation and global transmission. Our data furthermore suggest certain geographies are more prone to transmission events and should receive additional attention.

- Uterine leiomyomata (UL) are the most common tumours of the female genital tract and the primary cause of surgical removal of the uterus. Genetic factors contribute to UL susceptibility. To add understanding to the heritable genetic risk factors, we conduct a genome-wide association study (GWAS) of UL in up to 426,558 European women from FinnGen and a previous UL meta-GWAS. In addition to the 50 known UL loci, we identify 22 loci that have not been associated with UL in prior studies. UL-associated loci harbour genes enriched for development, growth, and cellular senescence. Of particular interest are the smooth muscle cell differentiation and proliferation-regulating genes functioning on the myocardin-cyclin dependent kinase inhibitor 1A pathway. Our results further suggest that genetic predisposition to increased fat-free mass may be causally related to higher UL risk, underscoring the involvement of altered muscle tissue biology in UL pathophysiology. Overall, our findings add to the understanding of the genetic pathways underlying UL, which may aid in developing novel therapeutics.

- Introduction: The aim was to describe and compare changes in the reproductive pattern of women in their 40s observed over a decade in Scandinavia. Material and Methods: Cross-sectional study using the total population of women aged 40-49 years between 2008-2018 in Denmark, Norway and Sweden (on average n = 1.5 million). Aggregated data concerning birth and induced abortion rate were collected and analyzed from national health registers. National data on redeemed prescriptions of hormonal contraceptives in the three countries were collected from prescription registers. Births after spontaneous and assisted conceptions were identified by using cross-linked data on deliveries from the Medical Birth Registers and National Registers of Assisted Reproduction in the three countries. Results: Use of hormonal contraception increased among women aged 40-44 years in Denmark from 24% to 31%, in Sweden from 27% to 30%, and in Norway from 22% to 24%. The levonorgestrel-releasing intrauterine device was the most frequently used method in all countries. Birth rates among women 40-44 years increased continuously from 9.5 to 12/1000 women in Denmark and from 11.7 to 14.3/1000 in Sweden, but remained stable in Norway at similar to 11/1000 women. There was a doubling of assisted conceptions in Denmark from 0.71 to 1.71/1000 women, Sweden from 0.43 to 0.81/1000 and Norway from 0.25 to 0.53/1000 women 40-49 years of age. Sweden had the highest induced abortion rate (7.7 to 8.1/1000 women) in women aged 40-49 years during the study period. Conclusions: From 2008 to 2018, birth rates continuously increased among women aged 40-49 years in Denmark and Sweden and births resulting from assisted reproductive technology doubled in all three countries.

- "Very early medical abortion " (VEMA) refers to medical abortion (with mifepristone and misoprostol) before intrauterine pregnancy is visualized on ultrasound. Our aim is to present the current evidence on efficacy, safety (focused on ectopic pregnancies), and how to assess treatment success of VEMA. We conducted a systematic review of studies reporting outcomes of VEMA. The field is small and so our objective was to map all relevant literature, without conducting meta-analysis. We searched PubMed, Medline, and Embase on April 19, 2022. We conducted a narrative synthesis of the evidence. A total of 373 articles were identified. Six articles (representing four observational and one pilot trial) were included in the final review. Across all included studies, treatment efficacy ranged between 91 and 100%. Prevalence of ectopic pregnancy was low and very few cases ( n = 2) of ruptures were reported. Most studies used serial serum human chorionic gonadotrophin (s-hCG) levels to determine success of abortion; one study used low sensitivity urine hCG. From the available evidence, VEMA appears to be efficacious and does not appear to cause harm to ectopic pregnancies. Treatment can be assessed with pre- and postabortion s-hCG. Good quality, randomized controlled trial evidence is needed to best inform practice.
