Somatic mutation phasing informs our understanding of cancer-related events, like driver mutations. We generated linked-read whole genome sequencing data for 23 samples across disease stages from 14 multiple myeloma (MM) patients and systematically assigned somatic mutations to haplotypes using linked-reads. Here, we report the reconstructed cancer haplotypes and phase blocks from several MM samples and show how phase block length can be extended by integrating samples from the same individual.

Background: The public health measures associated with the COVID-19 pandemic may have indirectly impacted other health outcomes, such as falls among older adults. The purpose of this study was to examine trends in fall-related hospitalizations and emergency department visits among older adults before and during the COVID-19 pandemic in Ontario, Canada.

Methods: We obtained fall-related hospitalizations (N = 301,945) and emergency department visit (N = 1,150,829) data from the Canadian Institute for Health Information databases from 2015 to 2022 for adults ages 65 and older in Ontario.

Placenta accreta spectrum (PAS) comprising placenta accreta, increta, and percreta, is 1 of the leading causes of peripartum hemorrhage and accounts for up to 50% of all cesarean hysterectomies (CH). We analyzed the data of 216 parturients with PAS who underwent cesarean delivery (CD) and/or CH. Intraoperative surgical complications were noted in 215 (99.
