A Quality Improvement Initiative to Reduce the Frequency of Delays in Initiation and Restarts of Continuous Renal Replacement Therapy.

Background: Continuous renal replacement therapy (CRRT) is a lifesaving intervention for critically ill patients. Delays in initiation, or an inability to resume CRRT following a temporary suspension in therapy (CRRT restart), can result in suboptimal CRRT delivery.

Local Problem: Intensive care units across the health care system were experiencing significant delays in CRRT initiation and restarts.

Clinical, imaging, and intervention factors associated with the upgrade of isolated flat epithelial atypia.

Purpose: This study aims to determine clinical, imaging, and intervention factors associated with the upgrade of flat epithelial atypia (FEA) diagnosed on vacuum-assisted biopsy (VAB) in order to formulate criteria for excision and better assist in management.

Methods: Between 2012 and 2015, 254 patients had a form of atypia diagnosed on ultrasound, MRI or stereotactic VAB and met eligibility for this study. Demographic, imaging, biopsy and pathology characteristics were analyzed for association with upgrade.

Long-term impacts of nitrogen deposition on coastal plant communities.

Nitrogen deposition has been shown to have significant impacts on a range of vegetation types resulting in eutrophication and species compositional change. Data from a re-survey of 89 coastal sites in Scotland, UK, c. 34 years after the initial survey were examined to assess the degree of change in species composition that could be accounted for by nitrogen deposition.

Species composition of coastal dune vegetation in Scotland has proved resistant to climate change over a third of a century.

Climate change is expected to have an impact on plant communities as increased temperatures are expected to drive individual species' distributions polewards. The results of a revisitation study after c. 34 years of 89 coastal sites in Scotland, UK, were examined to assess the degree of shifts in species composition that could be accounted for by climate change.

An intra-abdominal abscess or "rind" as a consequence of peritoneal dialysis-associated pseudomonas peritonitis.

Background: Abdominal CT imaging has defined characteristics of two pathological entities specific to peritoneal dialysis patients. Both are associated with serious peritoneal complications. One is comprised of ascites accompanied by septation and loculated fluid pockets as a complication of bacterial peritonitis.

Selective and antagonistic functions of SWI/SNF and Mi-2beta nucleosome remodeling complexes during an inflammatory response.

Studies of mammalian genes activated in response to an acute stimulus have suggested diverse mechanisms through which chromatin structure and nucleosome remodeling events contribute to inducible gene transcription. However, because of this diversity, the logical organization of the genome with respect to nucleosome remodeling and gene induction has remained obscure. Numerous proinflammatory genes are rapidly induced in macrophages in response to microbial infection.
