Concerns have been raised over wide variation in rates of unplanned (emergency or urgent) surgery for access-sensitive surgical conditions—diagnoses requiring that preferably is planned (elective) but, when access limited, may be delayed until worsening symptoms require riskier and costlier surgery. Yet little known about geographic community-level factors increase the likelihood with adverse outcomes. We examined relationship between social vulnerability three conditions 2014–18 among...

Primary care physicians are often the first to screen and identify patients with access-sensitive surgical conditions that should be treated electively. These require surgery is preferably planned (elective), but, when access limited, treatment may delayed worsening symptoms lead emergency (for example, colectomy for cancer, abdominal aortic aneurysm repair, incisional hernia repair). We evaluated rates of elective versus three living in primary Health Professional Shortage Areas during...

Abstract Notch activation is highly prevalent among cancers, in particular T-cell acute lymphoblastic leukemia (T-ALL). However, the use of pan-Notch inhibitors to treat cancers has been hampered by adverse effects, particularly intestinal toxicities. To circumvent this barrier T-ALL, we aimed inhibit ETS1, a developmentally important transcription factor previously shown cobind response elements. Using complementary genetic approaches mouse models, show that ablation Ets1 leads strong...

Abstract Purpose Americans who reside in health professional shortage areas currently have less than half of the needed physician workforce. While designation has been associated with poor outcomes for chronic medical conditions, far is known about after high‐risk surgical procedures. Methods We performed a retrospective review Medicare beneficiaries living and nonshortage underwent abdominal aortic aneurysm repair, coronary artery bypass graft, esophagectomy, liver resection,...

Objective: Health professional shortage areas (HPSAs) were created by the Resources and Services Administration to identify communities with a of clinical providers. For medical conditions, these designations are associated worse outcomes. However, far less is known about patients undergoing high-complexity surgical procedures, such as coronary artery bypass grafting (CABG). Background: The aim was compare postoperative outcomes surgery in beneficiaries living HPSA versus non-HPSA designated...

Objective: To compare the rates of unplanned procedures for access-sensitive surgical conditions among beneficiaries living in census tracts varying social capital levels. Background: Access-sensitive are ideally screened and treated an elective setting. However, when left untreated, these may result (i.e., urgent or emergent) surgery. It is possible that capital—the resources available to individuals through their membership a network—may impact likelihood planned procedure occurring....
