Benchmarking lung cancer screening programmes with adaptive screening frequency against the optimal screening schedules derived from the ENGAGE framework: a comparative microsimulation study.

Background: Lung cancer screening recommendations employ annual frequency for eligible individuals, despite evidence that it may not be universally optimal. The impact of imposing a structure on the screening frequency remains unknown. The ENGAGE framework, a validated framework that offers fully dynamic, analytically optimal, personalised lung cancer screening recommendations, could be used to assess the impact of screening structure on the effectiveness and efficiency of lung cancer screening.

Daikenchuto, a Japanese herbal medicine, ameliorates experimental colitis in a murine model by inducing secretory leukocyte protease inhibitor and modulating the gut microbiota.

Background: Inflammatory bowel disease (IBD) is a refractory inflammatory disorder of the intestine, which is probably triggered by dysfunction of the intestinal epithelial barrier. Secretory leukocyte protease inhibitor (SLPI) secreted by colon epithelial cells protects against intestinal inflammation by exerting anti-protease and anti-microbial activities. Daikenchuto (DKT) is one of the most commonly prescribed Japanese traditional herbal medicines for various digestive diseases.

Estimating sojourn time and sensitivity of screening for ovarian cancer using a Bayesian framework.

Background: Ovarian cancer is among the leading causes of gynecologic cancer-related death. Past ovarian cancer screening trials using combination of cancer antigen 125 testing and transvaginal ultrasound failed to yield statistically significant mortality reduction. Estimates of ovarian cancer sojourn time-that is, the period from when the cancer is first screen detectable until clinical detection-may inform future screening programs.

Co-occurrence of Epstein-Barr virus-positive nodal T/NK-cell lymphoma and nodal T-follicular helper cell lymphoma of different clonal origins: An autopsy case report.

Nodal T-follicular helper cell lymphoma (TFHL) is a subset of T-cell lymphoma and frequently co-occurs with Epstein-Barr virus (EBV)-positive B-cell lymphoma but not with T/NK-cell lymphoma. Recently, a new entity with a worse prognosis, called EBV-positive nodal T/NK-cell lymphoma (NTNKL) has been established. Here, we report an autopsy case of synchronous multiple lymphomas, including TFHL and NTNKL.
