Differences in postoperative prognosis between early-stage lung adenocarcinoma and squamous cell carcinoma.

Background: Although prognosis and treatments differ between small-cell- and nonsmall-cell carcinoma, comparisons of the histological types of NSCLC are uncommon. Thus, we investigated the oncological factors associated with the prognosis of early-stage adenocarcinoma and squamous cell carcinoma.

Methods: We retrospectively compared the clinicopathological backgrounds and postoperative outcomes of patients diagnosed with pathological stage I-IIA adenocarcinoma and squamous cell carcinoma primary lung cancer completely resected at our department from January 2007 to December 2017.

Performance of ChatGPT and Bard in self-assessment questions for nephrology board renewal.

Background: Large language models (LLMs) have impacted advances in artificial intelligence. While LLMs have demonstrated high performance in general medical examinations, their performance in specialized areas such as nephrology is unclear. This study aimed to evaluate ChatGPT and Bard in their potential nephrology applications.

Musashi-1 Is a Novel Immunohistochemical Marker of Neuroendocrine Carcinoma of the Lung.

Small cell lung cancer (SCLC) and large cell neuroendocrine carcinoma (LCNEC) have recently been grouped as lung neuroendocrine carcinomas (NECs). Because these lung NECs are clinically malignant and their treatment strategies differ from those of non-SCLC, the quality of diagnosis has a significant prognostic impact. The diagnosis of LCNEC requires positive immunohistochemical staining with chromogranin A, synaptophysin, and CD56, along with a morphological diagnosis, and insulinoma-associated protein 1 (INSM1) has been proposed as an additional marker but is still not an ideal or better marker.

Improvement of acceptability in patients undergoing esophagogastroduodenoscopy using auditory and visual stimulation.

Esophagogastroduodenoscopy (EGD) has become an indispensable examination to discover upper gastrointestinal diseases, including cancer, and perform endoscopic treatment. However, many individuals who undergo the procedure have feelings of anxiety and fear regarding EGD. Although the use of medication for sedation during EGD is useful for reducing anxiety and the stability of hemodynamics, sedation may increase the likelihood of complications.
