Neoadjuvant Immunotherapy Followed by Surgery Compared with Upfront Surgery Alone in Operable Colon Cancer with Deficient Mismatch Repair: Modeling Oncological Outcomes and Numbers Needed to Treat.

Background: Trials on neoadjuvant immunotherapy in operable colon cancer with deficient mismatch repair (dMMR) reported high pathological response rates in the surgical specimen, but long-term survival is not known. Neoadjuvant immunotherapy as a stand-alone therapy without subsequent radical surgery is currently not investigated in colon cancer.
Objective: The aim of this study was to model outcomes between trial data and real-world patients after surgery.
A Pilot Rapid Triage Process for Prehospital ST-Segment Myocardial Infarction Patients Direct to the Catheterization Lab.

Background Rapid treatment of ST-elevation myocardial infarction (STEMI) patients with primary percutaneous coronary intervention (PCI) significantly reduces morbidity and mortality rates. Recent studies emphasize the importance of reducing total ischemic time, making first-medical-contact-to-balloon (FMCTB) time a key performance indicator. To improve FMCTB times in patients brought to the Emergency Department (ED) by Emergency Medical Services (EMS), we implemented a "Direct to Lab" (DTL) workflow during the following conditions: weekday daytime hours, when the lab is fully staffed, and for hemodynamically stable STEMI patients presenting via EMS.

Objective: With the increasing energy surrounding the development of artificial intelligence and machine learning (AI/ML) models, the use of the same external validation dataset by various developers allows for a direct comparison of model performance. Through our High Throughput Truthing project, we are creating a validation dataset for AI/ML models trained in the assessment of stromal tumor-infiltrating lymphocytes (sTILs) in triple negative breast cancer (TNBC).
Materials And Methods: We obtained clinical metadata for hematoxylin and eosin-stained glass slides and corresponding scanned whole slide images (WSIs) of TNBC core biopsies from two US academic medical centers.
Activation of PLCβ enzymes by G and G proteins is a common mechanism to trigger cytosolic Ca increase. We and others reported that G inhibitor FR900358 (FR) can inhibit both and G- and, surprisingly, G-mediated intracellular Ca mobilization. Thus, the G-G-PLCβ-Ca signaling axis depends entirely on the presence of active G, which reasonably explained FR-inhibited G-induced Ca release.
