The David Versus the Bentall Procedure for Acute Type A Aortic Dissection.

: Type A aortic dissection (TAAD) is a life-threatening condition which requires prompt diagnosis and surgical treatment. When TAAD involves the aortic root, aortic valve-sparing or Bentall procedures are the main surgical treatment options. The subjects of this analysis were 3735 patients included in the European Registry of Type A Aortic Dissection (ERTAAD).

Malperfusion syndrome in patients undergoing repair for acute type A aortic dissection: Presentation, mortality, and utility of the Penn classification.

Background: The current study aims to report the presentation of the malperfusion syndrome in patients with acute type A aortic dissection admitted to surgery and its impact on mortality.

Methods: Data were retrieved from the multicenter European Registry of Type A Aortic Dissection. The Penn classification was used to categorize malperfusion syndromes.

The SpO/FiO Ratio Combined with Prognostic Scores for Pneumonia and COVID-19 Increases Their Accuracy in Predicting Mortality of COVID-19 Patients.

Identifying high-risk COVID-19 patients is critical for emergency department decision-making. Our study's primary objective was to identify new independent predictors of mortality and their predictive utility in combination with traditional pneumonia risk assessment scores and new risk scores for COVID-19 developed during the pandemic. : A retrospective study was performed in two Italian University Hospitals.

Failure to Rescue After Resection of Perhilar Cholangiocarcinoma in an International Multicenter Cohort.

Background: Failure to rescue (FTR) is defined as the inability to prevent death after the development of a complication. FTR is a parameter in evaluating multidisciplinary postoperative complication management. The aim of this study was to evaluate FTR rates after major liver resection for perihilar cholangiocarcinoma (pCCA) and analyze factors associated with FTR.

A magnetic mucus-penetrating nanoagent boosting phlegm elimination for inhalation injury treatment.

Inhalation injuries arising from exposure to toxic gases or smoke in fires or industrial accidents pose grave risks and significant respiratory complications. The limited efficacy of current treatment strategies stems from challenges in delivering therapeutic agents across the mucus barrier to the damaged trachea and bronchus. This research explores the reparative potential and underlying mechanisms of sputum-penetrable magnetic nanoparticles (MNPs) coated with poly(-isopropylacrylamide) (PNIPAM), combined with polyethylene glycol (PEG), and loaded with ambroxol hydrochloride (AH) (MNPs@PNIPAM-AH@PEG) as an innovative therapeutic approach for inhalation injuries.

Peceleganan Spray for the Treatment of Skin Wound Infections: A Randomized Clinical Trial.

Importance: Peceleganan spray is a novel topical antimicrobial agent targeted for the treatment of skin wound infections. However, its efficacy and safety remain unclear.

Objective: To assess the safety and efficacy of peceleganan spray for the treatment of wound infections.

Combining antibiotic-loaded bone cement-based free vastus lateralis muscle-sparing flap with split-thickness skin grafts: A reliable strategy for reconstructing diabetic foot ulcers at non-weight-bearing areas.

Diabetic foot ulcers (DFUs) present significant challenges due to their associated amputation rates, mortality, treatment complexity and excessive costs. Our earlier work introduced a wound surgical integrated treatment (WSIT) for DFUs, yielding promising outcomes. This study focuses on a specific WSIT protocol employing antibiotic-loaded bone cement (ALBC) in the first Stage, and free vastus lateralis muscle-sparing (VLMS) flaps and split-thickness skin grafts (STSGs) in the second stage to repair non-weight-bearing DFUs.

COVID-19: The Development and Validation of a New Mortality Risk Score.

The coronavirus disease 2019 (COVID-19) pandemic has found the whole world unprepared for its correct management. Italy was the first European country to experience the spread of the SARS-CoV-2 virus at the end of February 2020. As a result of hospital overcrowding, the quality of care delivered was not always optimal.

Higher Postoperative Mortality and Inferior Survival After Right-Sided Liver Resection for Perihilar Cholangiocarcinoma: Left-Sided Resection is Preferred When Possible.

Background: A right- or left-sided liver resection can be considered in about half of patients with perihilar cholangiocarcinoma (pCCA), depending on tumor location and vascular involvement. This study compared postoperative mortality and long-term survival of right- versus left-sided liver resections for pCCA.

Methods: Patients who underwent major liver resection for pCCA at 25 Western centers were stratified according to the type of hepatectomy-left, extended left, right, and extended right.

Diameter and dissection of the abdominal aorta and the risk of distal aortic reoperation after surgery for type A aortic dissection.

Background: Surgery for Stanford type A aortic dissection (TAAD) is associated with an increased risk of late aortic reoperations due to degeneration of the dissected aorta.

Methods: The subjects of this analysis were 990 TAAD patients who survived surgery for acute TAAD and had complete data on the diameter and dissection status of all aortic segments.

Results: After a mean follow-up of 4.

Baseline risk factors of in-hospital mortality after surgery for acute type A aortic dissection: an ERTAAD study.

Background: Surgery for type A aortic dissection (TAAD) is associated with high risk of mortality. Current risk scoring methods have a limited predictive accuracy.

Methods: Subjects were patients who underwent surgery for acute TAAD at 18 European centers of cardiac surgery from the European Registry of Type A Aortic Dissection (ERTAAD).

Analysis of Prevalence and Clinical Features of Aortic Stenosis in Patients with and without Bicuspid Aortic Valve Using Machine Learning Methods.

Aortic stenosis (AS) is the most commonly diagnosed valvular heart disease, and its prevalence increases with the aging of the general population. However, AS is often diagnosed at a severe stage, necessitating surgical treatment, due to its long asymptomatic period. The objective of this study was to analyze the frequency of AS in a population of cardiovascular patients using echocardiography (ECHO) and to identify clinical factors and features associated with these patient groups.

Preoperative arterial lactate and outcome after surgery for type A aortic dissection: The ERTAAD multicenter study.

Background: Acute type A aortic dissection (TAAD) is associated with significant mortality and morbidity. In this study we evaluated the prognostic significance of preoperative arterial lactate concentration on the outcome after surgery for TAAD.

Methods: The ERTAAD registry included consecutive patients who underwent surgery for acute type A aortic dissection (TAAD) at 18 European centers of cardiac surgery.

Human Keratinocytes and Fibroblasts Co-Cultured on Silk Fibroin Scaffolds Exosomally Overrelease Angiogenic and Growth Factors.

The optimal healing of skin wounds, deep burns, and chronic ulcers is an important clinical problem. Attempts to solve it have been driving the search for skin equivalents based on synthetic or natural polymers. Consistent with this endeavor, we used regenerated silk fibroin (SF) from to produce a novel compound scaffold by welding a 3D carded/hydroentangled SF-microfiber-based nonwoven layer (C/H-3D-SFnw; to support dermis engineering) to an electrospun 2D SF nanofiber layer (ESFN; a basal lamina surrogate).

Long-Term Effects of Severe Burns on the Kidneys: Research Advances and Potential Therapeutic Approaches.

Burns are a seriously underestimated form of trauma that not only damage the skin system but also cause various complications, such as acute kidney injury (AKI). Recent clinical studies have shown that the proportion of chronic kidney diseases (CKD) in burn patients after discharge is significantly higher than that in the general population, but the mechanism behind this is controversial. The traditional view is that CKD is associated with hypoperfusion, AKI, sepsis, and drugs administered in the early stages of burns.
