CT-Based Lung Size Matching in Delayed Chest Closure for Systemic Sclerosis Lung Transplantation.

Purpose: Delayed chest closure (DCC) during lung transplantation (LTx) is a controversial surgical approach that lacks research in systemic sclerosis (SSc) patients. We investigated outcomes, clinical risk factors, and CT-based lung size-matching parameters associated with DCC in SSc recipients.

Methods: This retrospective study included 92 SSc recipients (age 51 years ± 10, 56/92 (61.

Utilization of the Liver-First Approach in Combined Lung-Liver Transplant Provides Comparable Outcomes to the Traditional Lung-First Approach: A UNOS Study.

Multiorgan transplantation is offered to a selected group of patients every year. The sequence in which organs are transplanted depends on ischemic time graft tolerance and the sickest organ first strategy. In the case of Lung-Liver transplantation, lung allografts are usually implanted before the liver.

Pneumatosis Intestinalis and Pneumoperitoneum After Lung Transplantation: Single-Center Experience and Systematic Review.

Pneumatosis intestinalis (PI) and pneumoperitoneum are some of the complications after lung transplantation (LT). But only limited reports are published. The purpose of this study is to review our experience and perform a systematic review to discuss the possible causes, risk factors, and management.

Combined HDAC8 and checkpoint kinase inhibition induces tumor-selective synthetic lethality in preclinical models.

The elevated level of replication stress is an intrinsic characteristic of cancer cells. Targeting the mechanisms that maintain genome stability to further increase replication stress and thus induce severe genome instability has become a promising approach for cancer treatment. Here, we identify histone deacetylase 8 (HDAC8) as a drug target whose inactivation synergized with the inhibition of checkpoint kinases to elicit substantial replication stress and compromise genome integrity selectively in cancer cells.

Adoption of a semi-elective lung transplantation practice by safely extending cold ischemic times.

Objective: Lung transplantation is a complex surgical procedure performed by specialized teams. Practice changes to eliminate overnight lung transplants were implemented at our center and patient outcomes were evaluated.

Methods: Patient and donor organ selection were performed in the standard fashion.

Predicting post-lung transplant survival in systemic sclerosis using CT-derived features from preoperative chest CT scans.

Objectives: The current understanding of survival prediction of lung transplant (LTx) patients with systemic sclerosis (SSc) is limited. This study aims to identify novel image features from preoperative chest CT scans associated with post-LTx survival in SSc patients and integrate them into comprehensive prediction models.

Materials And Methods: We conducted a retrospective study based on a cohort of SSc patients with demographic information, clinical data, and preoperative chest CT scans who underwent LTx between 2004 and 2020.

A Core NRF2 Gene Set Defined Through Comprehensive Transcriptomic Analysis Predicts Selective Drug Resistance and Poor Multicancer Prognosis.

The nuclear factor erythroid 2-related factor 2-Kelch-like ECH-associated protein 1 (NRF2-KEAP1) pathway plays an important role in the cellular response to oxidative stress but may also contribute to metabolic changes and drug resistance in cancer. However, despite its pervasiveness and important role, most of nuclear factor erythroid 2-related factor 2 (NRF2) target genes are defined in context-specific experiments and analysis, making it difficult to translate from one situation to another. Our study investigates whether a core NRF2 gene signature can be derived and used to represent NRF2 activation in various contexts, allowing better reproducibility and understanding of NRF2.

Transmission of Severe Acute Respiratory Syndrome Coronavirus 2 Among Residents and Employees in a Veterans Affairs Community Living Center: A 42-Month Prospective Cohort Study.

Background: Understanding routes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission in long-term care facilities is essential for the development of effective control measures.

Methods: Between March 1, 2020, and August 31, 2023, we identified coronavirus disease 2019 (COVID-19) cases among residents and employees in a Veterans Affairs community living center that conducted routine screening for asymptomatic COVID-19. Contact tracing was conducted to identify suspected transmission events, and whole genome sequencing was performed to determine the relatedness of SARS-CoV-2 samples.

Performance status at the time of lung retransplant predicts long-term function.

Background: Lung retransplantation is offered to select patients with chronic allograft dysfunction. Given the increased risk of morbidity and mortality conferred by retransplantation, post-transplant function should be considered in the decision of who and when to list. The aim of this study is to identify predictors of post-operative disability in patients undergoing lung retransplantation.

Comprehensive Proteomic Analysis of the Differential Expression of 83 Proteins Following Intracortical Microelectrode Implantation.

Intracortical microelectrodes (IMEs) are devices designed to be implanted into the cerebral cortex for various neuroscience and neuro-engineering applications. A critical feature of these devices is their ability to detect neural activity from individual neurons. Currently, IMEs are limited by chronic failure, largely considered to be caused by the prolonged neuroinflammatory response to the implanted devices.

Outcomes following minimally invasive approaches . open extended lobectomy for non-small cell lung cancer: a propensity-matched analysis of the National Cancer Database.

Background: Traditional thoracotomy, an invasive surgical procedure, has been the standard approach for extended lobectomy in treating non-small cell lung cancer (NSCLC). However, minimally invasive surgery (MIS) has gained traction with advancements in surgical techniques. Despite this, the outcomes of extended lobectomy via a minimally invasive approach remain largely uncharted.

Lung transplantation in HIV seropositive recipients: An analysis of the UNOS registry.

Background: Experience with lung transplantation (LT) in patients with human immunodeficiency virus (HIV) is limited. Many studies have demonstrated the success of kidney and liver transplantation in HIV-seropositive (HIV+) patients. Our objective was to conduct a national registry analysis comparing LT outcomes in HIV+ to HIV-seronegative (HIV-) recipients.

Immediate Postoperative COVID-19 Infection after Lung Transplantation: A Systematic Review and Case Series.

Background: With new variants challenging the effectiveness of preventive measures, we are beginning to recognize the reality that COVID-19 will continue to pose an endemic threat. The manifestations of COVID-19 in lung transplant recipients during index admission are poorly understood with very few cases reported in recent lung transplant recipients. Optimal management of immunosuppression and antiviral therapy in recent transplant recipients is challenging.

A novel scoring system to predict survival in cirrhotic patients undergoing isolated lung transplantation: The PENS-CEPT score.

Cirrhosis is usually regarded as a contraindication to isolated lung transplantation (ILT). We sought to determine which patients with cirrhosis could safely undergo ILT. Based on a retrospective analysis of patients with cirrhosis who underwent ILT at our center between 2007 and 2020, we developed an exclusionary algorithm (PENS-CEPT: Pittsburgh ExclusioN Score in Cirrhotics Evaluated for Pulmonary Transplant) to help determine which patients can undergo ILT with minimal incurred risk from their underlying liver disease.

Impact of gastro-jejunostomy tube in lung transplant patients: a propensity-matched analysis.

Objectives: During the postoperative phase of lung transplantation, the surgical creation of a gastro-jejunostomy (GJ) may be deemed necessary for patients with severe oesophageal dysmotility, prolonged oral intake difficulties stemming from use of a ventilator or marked malnutrition. We explored the effects of postoperative GJ tube on survival and bronchiolitis obliterans syndrome in lung transplant recipients.

Methods: We retrospectively reviewed all lung transplants performed at our institution between 2011 and 2022.
