Post-implant transcatheter aortic prosthesis deformation: tricuspid versus bicuspid valve.

Objective: We sought to assess whether post-implant transcatheter aortic valve prosthesis multi detector computed characteristics differ between patients with native tricuspid and bicuspid aortic valve stenosis, as well as the effect on valve performance and clinical implications.

Methods: We analysed 100 consecutive post-implant multi detector computed tomography scans to assess self-expandable prosthesis non-uniform expansion at six pre-specified valvular levels, and other specific parameters, including valvular and perivalvular thrombosis at six months follow-up. Echocardiographic prosthesis performance and clinical outcome was also evaluated.

Veno-venous extracorporeal membrane oxygenation (VV ECMO) cannula malposition identified with point-of-care ultrasound.

Background: Point-of-care ultrasound (POCUS) has become a mainstay in the evaluation of critically ill patients in the intensive care unit (ICU). ECMO patients are susceptible to complications during prolonged ICU stay, including cannula malposition, which has deleterious consequences. Although the literature surrounding utility of ultrasound on ECMO patients is expansive, direct comparison between radiographic imaging versus ultrasound for identification of cannula malposition is lacking.

Disruption of the circadian rhythm of melatonin: A biomarker of critical illness severity.

Circadian dysrhythmias occur commonly in critically ill patients reflecting variable effects of underlying illness, ICU environment, and treatments. We retrospectively analyzed the relationship between clinical outcomes and 24-h urinary 6-sulfatoxymelatonin (aMT6s) excretion profiles in 37 critically ill patients with shock and/or respiratory failure. Nonlinear regression was used to fit a 24-h cosine curve to each patient's aMT6s profile, with rhythmicity determined by the zero-amplitude test.

Non-tuberculous mycobacterial thoracic osteomyelitis in an immunocompetent host: a rare presentation of .

An immunocompetent man in his 40s presented with 3 months of mid-thoracic back pain which progressed to include progressive paraesthesias and lower extremity weakness. Investigations revealed thoracic spine osteomyelitis with signs of cord compression. He underwent neurosurgical intervention, including laminectomy, spinal cord decompression and partial resection of an epidural mass.

Evaluation of the Antibacterial Activity of 75 Mushrooms Collected in the Vicinity of Oxford, Ohio (USA).

Antibiotic-resistant bacteria are an increasing and serious health concern worldwide, and multidrug-resistant pathogens are increasingly emerging among patients across the United States. Researchers are exploring sources of traditional medicines, including mushrooms, to find new antibiotic compounds. In this study, the antibiotic activities of 75 mushrooms collected in the area surrounding Oxford, Ohio (USA), were assayed for antibiotic activity against 6 bacterial strains (Pseudomonas aeruginosa reference strains PAO1 and PA14, P.

Comparison of endoscopic sinus surgery with and without image guidance.

Background: Image guidance based on preacquired computed tomography scans of the patient is a technique used to assist the physician during endoscopic sinus surgery (ESS). This study seeks to compare ESS with and without image guidance, analyzing a number of parameters that can impact on efficacy.

Methods: Retrospective chart review took place at a tertiary care referral center.
