The aim of this study was to report the safety, efficacy, and early results of tracheostomy in patients with COVID-19 and determine whether differences exist between percutaneous and open methods.

Prolonged respiratory failure is common in symptomatic patients with COVID-19, the disease process caused by infection with the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Tracheostomy, although posing potential risk to the operative team and other healthcare workers, may be beneficial for safe weaning of sedation and ventilator support. However, short- and long-term outcomes remain largely unknown.

A prospectively collected database of patients with COVID-19 undergoing tracheostomy at a major medical center in New York City between April 4 and April 30, 2020 was reviewed. The primary endpoint was need for continued mechanical ventilation. Secondary outcomes included complication rates, sedation weaning, and need for intensive care unit (ICU) level of care. Patient characteristics, perinuous intravenous sedation and mechanical ventilation. Continued follow-up of these patients to ascertain long-term outcome data is ongoing.
Tracheostomy under apneic conditions by either percutaneous or open technique can be safely performed in patients with respiratory failure due to COVID-19. Tracheostomy facilitated weaning from continuous intravenous sedation and mechanical ventilation. Continued follow-up of these patients to ascertain long-term outcome data is ongoing.
To define the current status of "difficult" LLR, a global database was created and investigated.

In the Second International Consensus Conference in 2014, minor LLR was considered as a standard practice and major LLR remained an innovative procedure. Since then, no updates on worldwide trends have been available.

A questionnaire on all consecutive patients who underwent difficult LLR (major hepatectomy, posterosuperior segmentectomy, sectionectomy, living donor hepatectomy, tumor size ≥10 cm, Child-Pugh grade ≥B, combined with biliary reconstruction, and Iwate criteria difficulty score ≥7) in 2014-2018 was distributed via email to 65 high-volume LLR centers worldwide. Individual data on patient and tumor demographics, surgical information, and short-term outcomes were obtained to create a large-scale international registry for analyses.

Overall, 58 centers in 19 countries performed 4478 difficult LLR (median, 58.5; range, 5-418) during the study period. learn more Hepatocellular carcinoma accounted for ≥40% of all indications. Half of the patients underwent major hepatectomy, followed by sectionectomy, posterosuperior segmentectomy, and living donor hepatectomy. In the vast majority of procedures, Clavien-Dindo grade ≥IIIa complication rates of ≈10% and 90-day mortality rates of ≈1% were achieved. Left or right trisectionectomy had the worst Clavien-Dindo grade ≥IIIa complication rate of ≥10% and 90-day mortality rate of 5%-10%. No significant correlation was observed between center volume and short-term outcomes.

Total 4478 patients underwent difficult LLR worldwide in 2014-2018. Most procedures are safe and feasible when conducted in specialized centers.

New onset atrial fibrillation commonly occurs following cardiac surgery and is associated with increased rates of stroke and mortality. In non-surgical patients with atrial fibrillation, novel oral anticoagulants (NOACs) have been shown to confer equivalent benefits for stroke prevention with less bleeding risk and less tedious monitoring requirements compared with Warfarin. However, NOACs have yet to be adopted widely in cardiac surgery patients. The NEW-AF study has been designed as a pragmatic, prospective, randomized controlled trial that will compare financial, convenience and safety outcomes for patients with new onset atrial fibrillation after cardiac surgery who are treated with NOACs versus Warfarin. Study results may contribute to optimizing the options for stroke prophylaxis in cardiac surgery patients and catalyze more widespread application of NOAC therapy in this patient population. The trial is registered with clinicaltrials.gov under registration number NCT03702582Rationale and Design of the Randomized Controlled Trial of New Oral Anticoagulants vs. Warfarin for post Cardiac Surgery Atrial Fibrillation The NEW-AF Trial.
Our goal was to describe contemporary management and in-hospital mortality associated with blunt thoracic aortic intimal tears (IT) within the American College of Surgeons Trauma Quality Improvement Program.

The evidence basis for nonoperative expectant management of traumatic IT of the thoracic aorta remains weak.

All adult patients with a thoracic aortic IT following blunt trauma were captured from Level I and II North American Centers enrolled in Trauma Quality Improvement Program from 2010 to 2017. For each patient, we extracted demographics, injury characteristics, the timing and approach of thoracic aortic repair and in-hospital mortality. Mortality attributable to IT was calculated by comparing IT patients to a propensity-score matched control cohort of severely injured blunt trauma patients without aortic injury.

There were 2235 IT patients across 330 facilities. Injury most often resulted from motor vehicle collision (74%). A total of 763 patients (34%) underwent operative management, with 94% (N = 714) of repairs performed via an endovascular approach. Median time to surgery was 11 hours (IQR 4-40). The frequency of operative management was higher in patients without traumatic brain injury (TBI) (35%, N = 679) compared to those with TBI (28%, N = 84) (P = 0.017). Compared to severely injured blunt trauma patients without aortic injury, IT was not associated with additional in-hospital mortality (11.0% for IT vs 12.1% for no IT, absolute risk difference -1.2%, 95% CI -3.1% to 0.7%).

The majority of blunt thoracic IT are managed nonoperatively and IT does not confer additional in-hospital mortality risk. Future studies should focus on the risk of injury progression.
