Population-based hospitalization burden estimates for respiratory viruses, 2015-2019.

Background: Acute respiratory infections (ARIs) result in millions of illnesses and hundreds of thousands of hospitalizations annually in the United States. The responsible viruses include influenza, parainfluenza, human metapneumovirus, coronaviruses, respiratory syncytial virus (RSV), and human rhinoviruses. This study estimated the population-based hospitalization burden of those respiratory viruses (RVs) over 4 years, from July 1, 2015 to June 30, 2019, among adults ≥18 years of age for Allegheny County (Pittsburgh), Pennsylvania.

A Sleeve-Sheath With a Coaxial Exchangeable Catheter for Palliative Evacuation of Recurrent Thoracic and Abdominal Effusions.

Herein we describe an outer cannula sleeve-sheath with a coaxially inserted exchangeable drainage catheter (SCDC) for effective evacuation of recurrent symptomatic fluid collections in the thorax and abdomen on patients in lieu of, or failed, current evacuation catheters and methods. The design is an alternative to existing commercially available devices and adds distinct enhancements with the possibility of intrathoracic or intrabdominal trans outer sleeve-sheath diagnostic or therapeutic interventions. This device aims at requiring a single invasive procedure (thoracentesis and paracentesis) while offering catheter exchange and repositioning if malfunction or malposition occurs during the patient's lifetime.

Estimating the burden of adult hospitalized RSV infection including special populations.

Background: Numerous studies in the U.S. have made estimates of the RSV burden among adults that vary widely due to differences in methodology, reliance on influenza surveillance, which does not adequately capture all RSV clinical symptoms, and lack of diagnostic methods to identify RSV when viral loads are low.

Agreement among sources of adult influenza vaccination in the age of immunization information systems.

Introduction: Many vaccination studies rely on self-reported vaccination status, with its inherent biases. Accuracy of influenza vaccination self-report has been evaluated periodically, typically using the medical record as the gold standard. The burgeoning of electronic medical records (EMRs) and immunization information systems (IISs) and the rise of adult vaccine administration in community pharmacies suggest the need for a reevaluation of self-reported vaccination status.

Percutaneous management of enterocutaneous fistulae and abscess-fistula complexes.

Abscess-fistula complexes and enterocutaneous fistulae are due to postoperative, spontaneous, and inflammatory etiologies. Conservative, percutaneous, endoscopic, and surgical treatment options are available options. Interventional radiologists have an array of different treatment strategies, often starting with percutaneous drainage of associated intra-abdominal abscesses.
