More isn't always better: antibiotic duration after surgical decortication in pleural empyema.

Background: While ample high-level evidence supports the limited use of antibiotics post-source control in intraabdominal infections, there is a paucity of available data in guiding antibiotic duration for intrathoracic infections. This study aims to analyze patient outcomes among those who have undergone surgical decortication for parapneumonic pleural empyema, comparing cases managed with infectious disease (ID) specialists against those without, and to identify predictive factors influencing antibiotic duration post-source control. We hypothesized that antibiotic duration would vary depending on the involvement of ID specialists.

Percutaneous Dilatational Tracheostomy in a Cardiac Surgical Intensive Care Unit: A Single-Center Experience.

Background: A significant proportion of cardiac surgery intensive care unit (CSICU) patients require long-term ventilation, necessitating tracheostomy placement. The goal of this study was to evaluate the long-term postoperative outcomes and complications associated with percutaneous dilatational tracheostomy (PDT) in CSICU patients.

Methods: All patients undergoing PDT after cardiac, thoracic, or vascular operations in the CSICU between January 1, 2013 and January 1, 2021 were identified.

Chest neck anastomotic leak post esophagectomy for malignancy: rate, predictors, and outcomes.

Background: Anastomotic leak is a major contributor to comorbidity and mortality following esophagectomy. We sought to assess rate and predictors of leak after esophagectomy and compare outcomes of chest versus neck anastomotic leaks.

Methods: A retrospective review was performed utilizing National-Surgical-Quality-Improvement-Program data from 2016-2019 for patients undergoing esophagectomy for malignancy.

Specialized pro-resolving mediators as modulators of immune responses.

Specialized pro-resolving mediators (SPMs) are endogenous small molecules produced mainly from dietary omega-3 polyunsaturated fatty acids by both structural cells and cells of the active and innate immune systems. Specialized pro-resolving mediators have been shown to both limit acute inflammation and promote resolution and return to homeostasis following infection or injury. There is growing evidence that chronic immune disorders are characterized by deficiencies in resolution and SPMs have significant potential as novel therapeutics to prevent and treat chronic inflammation and immune system disorders.

Utilization of Supplemental Regional Anesthesia in Lobectomy for Lung Cancer in the United States: A Retrospective Study.

Background: Pulmonary lobectomy is the standard of care for the treatment of early-stage non-small cell lung cancer. This study investigated the rate of utilization of supplemental anesthesia in patients undergoing video-assisted thoracoscopic surgery (VATS) or open lobectomy using a national database and assessed the effect of regional block (RB) on postoperative outcomes.

Methods: Patients who underwent lobectomy for lung cancer between 2014-2019 were identified in the American College of Surgeons National Surgical Quality Improvement Program.

Donation after cardiac death in heart transplantation: is there an ethical dilemma?

Purpose Of Review: In an attempt to address the organ shortages in heart transplantation, USA centres have begun utilizing donation after cardiac death (DCD) as an alternative to traditional donation after brain death (DBD). As this paradigm continues to expand, there is a need to address the medico-legal and ethical aspects of DCD donation, which is the focus of the current review.

Recent Findings: Current protocols use criteria established by the Uniform Determination of Death Act (UDDA), which is explicit in defining the irreversibility of circulation and brain function in determining death.

Bochdalek Hernia With Gastric Necrosis Requiring Roux-en-Y Esophagojejunostomy.

Bochdalek hernias are the most common congenital diaphragmatic hernias and are usually diagnosed during childhood. They can present in adulthood and, in uncommon circumstances, result in gastric herniation with strangulation. We present a case of an adult Bochdalek hernia resulting in total gastric necrosis necessitating Roux-en-Y esophagojejunostomy in an otherwise healthy 39-year-old man.

Trends in open lobectomy outcomes for lung cancer over the last 15 years: national cohort.

Objective: Adoption of thoracoscopic lobectomy has been increasing in the US; however, open lobectomy (OL) is still performed in half of the cases. Postoperative care and enhanced recovery after surgery (ERAS) pathways have evolved and improved outcomes. The study aims to evaluate postoperative outcomes of OL over the last 15 years.

Ischemia-reperfusion Injury in the Transplanted Lung: A Literature Review.

Lung ischemia-reperfusion injury (LIRI) and primary graft dysfunction are leading causes of morbidity and mortality among lung transplant recipients. Although extensive research endeavors have been undertaken, few preventative and therapeutic treatments have emerged for clinical use. Novel strategies are still needed to improve outcomes after lung transplantation.

Enhanced Recovery After Thoracic Surgery.

Enhanced recovery pathways (ERPs), used across multiple surgical subspecialties, is a multidisciplinary delivery of perioperative care designed to lessen the psychological stress of patients undergoing surgery. Thoracic ERP has been implemented but is not widespread, and variations exist between programs. Evidence of the benefit of thoracic ERP is emerging.

First, We Do Harm: Obtaining Informed Consent for Surgical Procedures.

Although many believe that the phrase "First, do no harm" was part of the Hippocratic Oath, in fact it was not. This phrase, often written in Latin ("Primum non Nocere"), seems to have first appeared in medical writing in the 17th century. However, it is obvious that many therapeutic interventions do cause at least some harm with hopes of benefitting patients in the long run.

Predictive value of pulmonary function measures for short-term outcomes following lung resection: analysis of a single high-volume institution.

Despite the importance of preoperative risk-stratification, there is a lack of consensus on how to identify high-risk patients for pulmonary resection. Enrollment criteria for national trials propose one definition based on preoperative pulmonary function tests. We sought to examine the value of preoperative forced expiratory volume in 1 second (FEV1) and diffusion capacity for carbon monoxide (DLCO) to predict short-term outcomes following pulmonary resection.

Specific Donor HLA-DR Types Correlate With Altered Susceptibility to Development of Chronic Lung Allograft Dysfunction.

Background: The greatest challenge to long-term graft survival is the development of chronic lung allograft dysfunction. Th17 responses to collagen type V (colV) predispose lung transplant patients to the severe obstructive form of chronic lung allograft dysfunction, known as bronchiolitis obliterans syndrome (BOS). In a previous study cohort (n = 54), pretransplant colV responses were increased in recipients expressing HLA-DR15, consistent with the high binding avidity of colV (α1) peptides for HLA-DR15, whereas BOS incidence, which was known to be strongly associated with posttransplant autoimmunity to colV, was higher in patients who themselves lacked HLA-DR15, but whose lung donor expressed it.

Modeling the Effect of the Aryl Hydrocarbon Receptor on Transplant Immunity.

Background: Exposure to pollutants through inhalation is a risk factor for lung diseases including cancer, asthma, and lung transplant rejection, but knowledge of the effects of inhaled pollutants on pathologies outside of the lung is limited.

Methods: Using the minor-mismatched model of male C57BL/6J (B6) to female B6 skin grafts, recipient mice were treated with an inhaled urban dust particle sample every 3 days before and after grafting. Graft survival time was determined, and analysis of the resulting immune response was performed at time before rejection.

Lung transplantation for high-risk patients with idiopathic pulmonary fibrosis.

Background: Survival for patients with idiopathic pulmonary fibrosis (IPF) and high lung allocation score (LAS) values may be significantly reduced in comparison to those with lower LAS values.

Objectives: To evaluate outcomes for high-risk IPF patients as defined by LAS values ≥46 (N=42) versus recipients with LAS values <46 (N=89).

Methods: We retrospectively reviewed records of 131 consecutive patients with IPF who received lung transplants at our institution between 1999 and 2013.

Amelioration of Clostridium difficile Infection in Mice by Dietary Supplementation With Indole-3-carbinol.

Objective: To determine the therapeutic effects of dietary supplementation on Clostridium difficile infection (CDI).

Background: With limited treatment options, the rise of C. difficile-associated disease has spurred on the search for novel therapies.

Timing and Frequency of Unplanned Readmissions After Lung Transplantation Impact Long-Term Survival.

Background: Adverse events that require hospital readmission frequently occur long after lung transplantation (LT) that has been successfully performed. We sought to identify the causes and rate of unplanned readmissions after LT and to determine whether unplanned readmissions have a significant impact on post-LT survival.

Methods: We retrospectively reviewed the outcomes in 174 LT recipients who underwent LT at our center from June 2005 to May 2014.

The presence or severity of pulmonary hypertension does not affect outcomes for single-lung transplantation.

Advanced lung disease (ALD) that requires lung transplantation (LTX) is frequently associated with pulmonary hypertension (PH). Whether the presence of PH significantly affects the outcomes following single-lung transplantation (SLT) remains controversial. Therefore, we retrospectively examined the outcomes of 279 consecutive SLT recipients transplanted at our centre, and the patients were split into four groups based on their mean pulmonary artery pressure values.
