Noninvasive positive pressure ventilation (NIPPV) plays an important role in the management of respiratory failure. However, since emergence COVID-19 pandemic, utilization traditional face mask NIPPV has been curtailed part due to risk aerosolization particles and subsequent health care worker exposure. A randomized clinical trial 2016 reported that alternative interface, helmet NIPPV, may be more effective than at preventing intubation improving mortality. The interface provides airway...

We present a case of 76 year-old, non-smoking Honduran female who was referred to our clinic for years persistent dry cough. Cardiac evaluation unremarkable. She denied symptoms heartburn, allergic rhinitis, and there no personal or family history asthma. Her physical exam demonstrated wheezing over the right mid-posterior chest. Spirometry within normal limits. CT-imaging chest middle lobe bronchus lingular segmental narrowing with bibasilar atelectasis mild interlobular septal thickening...

Aims Non‐cystic fibrosis bronchiectasis (NCFB) is a chronic progressive respiratory disorder occurring at rate ranging from 4.2 to 278.1 cases per 100,000 persons, depending on age, in the United States. For many patients with NCFB, presence of Pseudomonas aeruginosa (PA) makes treatment more complicated and typically has worse outcomes. Management NCFB can be challenging, warranting better understanding burden illness for treatments applied, healthcare resources used, subsequent costs....

Introduction: Vasoactive intestinal polypeptide tumors (VIPoma) are an extremely rare type of neuroendocrine tumor, with a worldwide incidence 1 in 10,000,000 people. VIPomas characterized by profuse watery diarrhea the secretory type. Case Report: A 45-year-old white female presented associated marked dehydration, electrolyte abnormalities, and weight loss. Her occurred day night. Physical exam demonstrated thin, fatigued female. She was tachycardic, her abdominal normal without tenderness...

6587 Background: Many individuals are concurrently eligible for multiple sources of government-reimbursed health services (e.g. Department Veterans Affairs (VA) and Medicare). Unclear is the impact on access, continuity care, disparities. We examined dual eligibility outcomes veterans with colorectal cancer initially treated surgically at VA hospitals. Methods: Retrospective analysis 13 years nationwide Medicare utilization data were conducted. Included patients diagnosed cancer, cure,...

3708 Background: Administrative databases have generally not been designed to permit cancer researchers readily follow patients forward from the period pre-diagnosis through initial curative intent treatment, adjuvant therapy, post-treatment follow-up, final endpoint of either death or loss follow-up. One major hurdle research using such has lack data as stage at diagnosis, and histopathologic type grade. A second is that many use more than one system care, in this instance, Department...

Introduction Mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene cause (CF), a disease which affects primarily respiratory and gastrointestinal (GI) tracts. The lifetime risk of colorectal cancer (CRC) patients with CF is approximately 5-10 times that general population. In 2018, Foundation CRC Screening Task Force recommended initiating screening adults at age 40. Case Presentations this case series, we present three cases females younger than 40 diagnosed...
