Understanding the impact of variable oxygen tension on mechanisms of perioperative organ injury and patient outcomes drives our research program. In a study of 367,000 surgical patients, the fraction of inspired oxygen varied widely from 100% to air (21%). The medical center and anesthesiologist who cared for the patient accounted for far more variability than patient or procedure factors. This non-patient-centered variation identifies an opportunity to determine the optimal approach to intraoperative oxygen administration. In preclinical studies, high oxygen increased kidney and brain injury and dysfunction; in clinical trials, surgical patients randomly assigned to hyperoxia had increased concentrations of markers of oxidative damage and impaired vascular reactivity compared to patients assigned to normoxia. We now have an opportunity to determine best practices for oxygen administration during surgery in a large multicenter clinical trial.</p>","PeriodicalId":23186,"journal":{"name":"Transactions of the American Clinical and Climatological Association","volume":"136 ","pages":"149-157"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13695165/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149273469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acute pancreatitis and chronic pancreatitis are risk factors for developing pancreatic cancer, suggesting a strong inflammatory role for disease initiation. Recently, we found that activin a (activin), a TGFβ superfamily member, drives inflammation in acute pancreatitis via recruitment of macrophages and activation of neutrophils. Here, we expand our studies in pancreatic cancer in the setting of inflammation and activin signaling. We performed digital spatial profiling (DSP) on a tissue section of human chronic pancreatitis with suspicion of pancreatic cancer to quantify more than 50 proteins relative to activin expression <i>in situ</i>. We found that activin co-localization is associated with reduced T cell activation and increased MAPK and PI3K signaling. These data suggest a previously underappreciated immunomodulatory role for activin in the setting of pancreatic cancer.</p>","PeriodicalId":23186,"journal":{"name":"Transactions of the American Clinical and Climatological Association","volume":"136 ","pages":"287-299"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13695175/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149273471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The production of pulmonary surfactant by alveolar type II (AT2) cells is required for functional ventilation. Pulmonary surfactant is produced in lamellar bodies in AT2 cells. Key components of pulmonary surfactant include phospholipids and surfactant proteins B (SP-B) and C (SP-C). Phospholipids are transported into lamellar bodies by ATP-binding cassette subfamily A member 3 (ABCA3) where they combine with SP-B and -C to form surfactant that is secreted into alveoli. Recessive loss of function mutations in surfactant protein B (<i>SFTPB</i>) and <i>ABCA3</i>, or monoallelic dominant mutations in surfactant protein C (<i>SFTPC</i>), can cause severe respiratory distress in term newborns, later-onset childhood interstitial lung disease (ChILD), or adult-onset ILD. Currently, no specific treatments for these diseases are available. Genetic therapies, including gene addition and gene editing strategies, offer the possibility to correct these defects in AT2 progenitor cells.</p>","PeriodicalId":23186,"journal":{"name":"Transactions of the American Clinical and Climatological Association","volume":"135 ","pages":"119-129"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12323473/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144795626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
