Outcomes of Partial Versus Total Colectomy in Ulcerative Colitis: A Propensity Score-Matched Analysis.

Introduction: Total abdominal colectomy (TAC) with ileostomy is the standard treatment for severe ulcerative colitis (UC). Partial colectomy (PC) with colostomy may present a less morbid treatment option.

Methods: The 2012-19 ACS-NSQIP database was queried to assess 30-day outcomes among patients undergoing TAC versus PC for UC, utilizing propensity score matching (PSM) techniques to account for differences in disease severity, patient selection, and presentation acuity.

Comparison of AlloDerm and AlloMax tissue incorporation in rats.

Background: Human acellular dermal matrices (HADMs) are used in a variety of settings. AlloMax is a new HADM currently being used for breast reconstruction and hernia repair. We compared the in vivo tissue integration of AlloMax to AlloDerm, a well-studied HADM, in rats.

Hydrogen fluoride inhalation injury because of a fire suppression system.

Automatic fire suppression systems (FSSs) use hydrofluorocarbons (HFCs) to chemically extinguish fires. At high temperatures, HFC can release hydrogen fluoride (HF), a toxic and potentially lethal gas. We report the deaths of three U.

Disruption of the mitotic kinesin Eg5 gene (Knsl1) results in early embryonic lethality.

Eg5, a member of the widely conserved kinesin-5 family, is a plus-end-directed motor involved in separation of centrosomes, and in bipolar spindle formation and maintenance during mitosis in vertebrates. To investigate the requirement for Eg5 in mammalian development, we have generated Eg5 deficient mice by gene targeting. Heterozygous mice are healthy, fertile, and show no detectable phenotype, whereas Eg5(-/-) embryos die during early embryogenesis, prior to the implantation stage.
