[Case of a Pleomorphic Carcinoma Successfully Treated with Nivolumab and Ipilimumab].

A 70-year-old man was referred to our hospital for an abnormal chest X-ray shadow. A chest CT scan showed a mass shadow with a cavitary lesion in segment 6 of the right lung. One year after radical resection(resection of the lower lobe of the right lung; pT2aN0M0, pStage ⅠB), the patient exhibited enlarged mediastinal lymph nodes and liver metastases, and postoperative recurrence was determined.

Evaluation of Race-Neutral Glomerular Filtration Rate Estimating Equations in an Indian Population.

Introduction: Glomerular filtration rate (GFR) estimation equations have not been extensively validated in the Indian population. Preliminary data showed that the widely used creatinine-based Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) 2009 significantly overestimated GFR in Indians. Newer estimated GFR (eGFR) equations based on creatinine and cystatin C, omitting the race, have been recently proposed.

Activation of the α7nAChR by GTS-21 mitigates septic tubular cell injury and modulates macrophage infiltration.

The most common and serious complication among hospitalized and critically ill patients is sepsis-associated acute kidney damage (S-AKI), which raises the risk of comorbidities and is linked to a high mortality rate. Cholinergic anti-inflammatory pathway (CAP), an anti-inflammatory pathway mediated by the vagus nerve, acetylcholine, and α7 nicotinic acetylcholine receptors (α7nAChRs), offers new perspectives for the treatment of S-AKI. In this study, we investigated the role of CAP and α7nAChR in kidney injury by employing an LPS-induced septic kidney injury mouse model and GTS-21 intervention.
