Given the strong association between relative wall thickness (RWT) and cardiovascular dysfunction, this study aims to explore RWT as a novel cardiovascular indicator to predict the risk of acute kidney injury (AKI) after lung cancer surgery and guide clinical interventions. This study retrospectively analyzed 170 patients who underwent video-assisted thoracoscopic surgery (VATS) for lung cancer in Nanjing First Hospital, China, between January 2022 and December 2023. Patients were divided into AKI group (n = 52) and non-AKI group (n = 118) based on the occurrence of AKI.

Background: Lung cancer is the main cause of cancer death in the world, with small-cell lung cancer (SCLC) accounting for about 10-15% of all lung cancers. Although programmed cell death protein 1 (PD-1)/programmed cell death ligand 1 (PD-L1) inhibitors represent a major breakthrough in SCLC treatment, only a minority of patients will benefit and there is still a lack of accurate biomarkers to guide clinical application. Inflammation plays a crucial role in tumorigenesis, tumor development, metastasis, and drug resistance, but there is limited research on the predictive value of these inflammatory indicators in SCLC.

Background: Acute type A aortic dissection (ATAAD) requires emergency surgery, but the choice of primary surgery remains controversial. It is believed that simple ascending aorta replacement may lead to higher postoperative survival rate, while the Sun procedure [frozen elephant trunk (FET) + total arch replacement (TAR)] performed in the first stage may obtain better long-term results. The study aimed to compare the outcome of ATAAD patients who underwent the Sun procedure with those without TAR + FET.

Background: This study aimed to evaluate the impact of severe asthma (SA) treatments after 12 months in achieving clinical remission (CR) within the context of the Severe Asthma Network in Italy (SANI) using the recent SANI definition of CR on treatment.

Methods: CR has been defined by SANI as complete, partial, and no CR. Complete CR is defined by the absence of oral corticosteroids (OCS), no symptoms, no exacerbations, and stable lung function, and partial CR requires the absence of OCS and the fulfillment of 2 out of the other 3 criteria.

Chitosan is generally considered to be a procoagulant effect, which may cause adverse phenomena such as blood clotting when used in small-diameter vascular grafts. However, it also shows good biocompatibility and anti-inflammatory properties, which can facilitate vascular reconstruction. Therefore, it is significant to transition the effect of chitosan from coagulation promotion to antiplatelet while still harnessing its bioactivity.

Peking University People's Hospital, Peking University Institute of Hematology, National Clinical Research Center for Treatment of Hematological Disease, Beijing Key Laboratory of Hematopoietic Stem Cell Transplantation for the Treatment of Hematological Diseases, Beijing, China.

Background: Severe pneumonia after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is associated with high mortality. Given that cytokine, including Interleukin-6 (IL-6), play a critical role in immune-mediated organ injury in patients with severe COVID-19, we hypothesized that cytokines may also contribute to the pathogenesis of severe pneumonia after allo-HSCT. This study aimed to investigate the role of IL-6 in severe pneumonia post-allo-HSCT and explore its underlying mechanism.

Background: Post-COVID-19 respiratory sequelae often involve lung damage, which is called residual lung abnormalities, and potentially lead to chronic respiratory issues. The adaptive immune response, involving T-cells and B-cells, plays a critical role in pathogen control, inflammation, and tissue repair. However, the link between immune dysregulation and the development of residual lung abnormalities remains unclear.

R. China.

Background: Lipoid pneumonia (LP) is a rare disease caused by the accumulation of lipids and lipid-laden macrophages in the alveoli inducing damage. LP is difficult to differentiate from other similar diseases without pathological evidence, such as upper respiratory tract infection (URTI), pneumonia, cryptogenic organizing pneumonia (COP), pulmonary alveolar proteinosis (PAP), lung mucinous adenocarcinoma and pulmonary edema. Given the high misdiagnosis rate and limited statistical clinical and treatment data, there is an urgent need for novel indicators of LP.

Background: Vascular endothelial growth factor (VEGF) is overexpressed in nasopharyngeal carcinoma and suppresses the anti-tumour immune response. Previous studies have shown that adding anti-VEGF treatment to PD-1 inhibition treatment strategies improves tumour response. We aimed to compare the efficacy of pembrolizumab, a PD-1 inhibitor, with or without bevacizumab, a VEGF inhibitor, in nasopharyngeal carcinoma.
