Pragmatic review of interventions to prevent catheter-associated urinary tract infections (CAUTIs) in adult inpatients.

Background: Urinary tract infections (UTIs) are one of the most common hospital-acquired complications. Insertion of a urinary catheter and the duration of catheterization are the main risk factors, with catheter-associated UTIs (CAUTIs) accounting for 70-80% of hospital-acquired UTIs. Guidance is available regarding the prevention of hospital-acquired CAUTIs; however, how best to operationalize this guidance remains a challenge.

Simultaneous medial and lateral hallucal sesamoid fractures in a basketball player mimicking bipartite sesamoid condition.

Simultaneous fractures of the medial and lateral hallucal sesamoids from sports injuries are an extremely uncommon occurrences, with only one case reported in a hurdler. We describe an unusual injury in a basketball player resulting in simultaneous fractures of the medial and lateral hallucal sesamoid bones, a presentation, which we believe has not been reported before in the literature. With a growing interest in sports, the frequency of such injuries will undoubtedly rise.

Confirmation and variability of the Allee effect incell populations, possible role of chemical signaling within cell clusters.

In studies of the unicellular eukaryote, many have anecdotally observed that cell dilution below a certain 'threshold density' causes cells to undergo a period of slow growth (lag). However, little is documented about the slow growth phase and the reason for different growth dynamics below and above this threshold density. In this paper, we extend and correct our earlier work to report an extensive set of experiments, including the use of new cell counting technology, that set this slow-to-fast growth transition on a much firmer biological basis.

Ultrasound-guided thrombin injection of genicular artery pseudoaneurysm.

Pseudoaneurysm is a rare complication after arthroscopic procedures involving the knee. A 38-year-old man presented 1 month after right-knee arthroscopy with a 2-cm pulsating mass on the medial side of the right knee. Duplex ultrasound evaluation revealed 2.

Operative outcomes after open repair of descending thoracic aortic aneurysms in the era of endovascular surgery.

Background: Since the advent of endovascular techniques for repair of descending thoracic aortic aneurysms (DTAAs), there has been a relative paucity of current data for open repairs. The purpose of this study was to assess the operative and long-term outcomes in a contemporary series of open repairs of DTAAs.

Methods: We conducted a retrospective review of 68 patients (63±14.
