Background: Both video-assisted thoracoscopic surgery (VATS) thymectomy and robot-assisted thoracoscopic surgery (RATS) thymectomy have been suggested as technically sound approaches for early-stage thymic epithelial tumors. However, the choice of VATS or RATS thymectomy for large and advanced thymic epithelial tumors remains controversial. In this study, the perioperative outcomes of VATS and RATS thymectomy were compared in patients with large thymic epithelial tumors (size ≥5.0 cm).
Methods: A total of 113 patients with large thymic epithelial tumors who underwent minimally invasive surgery were included. Sixty-three patients underwent RATS, and 50 patients underwent VATS. Patient characteristics and perioperative variables were compared.
Results: Compared with the VATS group, the RATS group experienced a shorter operation time (median: 110 min vs.130 min; P < 0.001) and less blood loss (30.00 ml vs. 100.00 ml, P < 0.001). No patients in the RATS group needed conversion to open surgery, but in the VATS series, five patients required conversion to open procedures (0% vs. 14.29%, P = 0.054). The rate of concomitant resection in the RATS group was similar to that in the VATS group (11.43% vs. 5.71%; P = 0.673). There was no significant difference between the two groups in the duration of chest tube (P = 0.587), postoperative complications (P = 1.000), and the duration of postoperative hospital stay (P = 0.141).
Conclusion: For large thymic epithelial tumors, RATS thymectomy can be performed safely and effectively in a radical fashion. Due to the advanced optics and precise instrument control, concomitant resections can be easily achieved in larger thymic epithelial tumors using the robotic approach.

Transplantation of the MSLN-deficient Thymus Generates MSLN Epitope Reactive T Cells to Attenuate Tumor Progression.

The development of mesothelin (MSLN) epitope reactive T cells is observed in mice that are immunized with the MSLN vaccine. Engineered T cells expressing MSLN-reactive high-affinity TCR exhibit extraordinary therapeutic effects for invasive pancreatic ductal adenocarcinoma in a mouse model. However, the generation of MSLN-reactive T cells through the introduction of MSLN-deficient thymus and the transplantation of the latter as a cure for cancer treatment have not been tested to date.

Airway inflammation, a hallmark feature of asthma, drives many canonical features of the disease, including airflow limitation, mucus plugging, airway remodeling, and hyperresponsiveness. The T2 inflammatory paradigm is firmly established as the dominant mechanism of asthma pathogenesis, largely due to the success of inhaled corticosteroids and biologic therapies targeting components of the T2 pathway, including IL-4, IL-5, IL-13, and thymic stromal lymphopoietin (TSLP). However, up to 30% of patients may lack signatures of meaningful T2 inflammation (ie, T2 low).

Objective: This study aimed to investigate the effects of cinnamaldehyde (CA) intervention on transient receptor potential melastatin 8 (TRPM8) expression in human nasal epithelial cells (HNECs) and mouse models of chronic rhinosinusitis (CRS) and determine the alleviating effects of CA on CRS.
Methods: HNECs were treated with CA, and the protein levels and mRNA expression of pro-inflammatory cytokines, namely, interleukin-25 (IL-25), IL-33, and thymic stromal lymphopoietin (TSLP), were measured by enzyme-linked immunosorbent assay and real-time reverse-transcription polymerase chain reaction (RT-PCR). TRPM8 expression levels were examined by RT-PCR and western blot.
Thymic stromal lymphopoietin (TSLP) is an alarmin cytokine activated by allergens, pathogens, and air pollutants. Recent studies suggest TSLP dysregulation in chronic inflammatory diseases. It was highlighted as a key player in the context of asthma-associated mucosal immunity.

Background And Purpose: We report the incidence, characteristics, and comorbidities of the complete unselected Danish cohort of patients with thymic epitheliums (TETs), which may serve as evidence for guiding treatment, surveillance, and counselling of TET patients.
Patients And Methods: All patients diagnosed with TETs from January 1st, 2015, to December 31st, 2020, were identified using the Danish Pathology Data Registry. Data on patient characteristics, comorbidities, and tumor histology were collected from electronic medical records available for all patients.
