TL;DR: The frequency of IVC filter placement has doubled over the past decade, and radiologists continue to perform more than half of all procedures, and the inpatient setting remains by far the most common site of service.
Abstract: Purpose The aim of this study was to evaluate trends in the placement and removal of inferior vena cava (IVC) filters in the Medicare population. Methods Summary Medicare claims data from 1999 through 2008 were used to identify the frequency of IVC filter placement procedures by specialty (radiology, surgery, cardiology, and all others) and site of service. Claims from 2003 (the first year the FDA cleared retrievable labeling for filters) through 2008 were used to identify intravascular foreign body retrieval procedures, and modeling was used estimate a frequency range of removal procedures. Trends over time were evaluated. Results Between 1999 and 2008, total Medicare fee-for-service beneficiary frequency of IVC filter placement procedures increased by 111.5% (30,756 to 65,041). Volumes increased for radiologists (16,531 to 36,829 [+122.8%]), surgeons (11,295 to 22,606 [+100.1%]), and cardiologists (1,025 to 4,236 [+313.3%]). Relative specialty market shares changed little over time. Volumes increased by 114.2% (26,511 to 56,774) and 229.1% (2,286 to 7,524) for hospital inpatients and outpatients, respectively, and decreased by 62.1% (1,959 to 743) for those in all other locations combined. In 2008, with 65,041 filters placed, only an estimated 801 to 3,339 (1.2 to 5.1%) were removed. Conclusion The frequency of IVC filter placement has doubled over the past decade, and radiologists continue to perform more than half of all procedures. Although volume has more than tripled in hospital outpatients, the inpatient setting remains by far the most common site of service. In the Medicare population, IVC filters are not commonly removed.

TL;DR: Based on the literature-based financial analyses, medical 3D printing appears to reduce operating room costs secondary to shortening procedure times, while resource-intensive, 3D printed constructs used in patients' operative care provides considerable downstream value to health systems.

TL;DR: Markedly increased use of the Twitter microblogging platform at recent RSNA annual meetings demonstrates the potential to leverage this technology to engage meeting attendees, improve scientific sessions, and promote improved collaboration at national radiology meetings.
Abstract: Purpose Twitter is a social media microblogging platform that allows rapid exchange of information between individuals. Despite its widespread acceptance and use at various other medical specialty meetings, there are no published data evaluating its use at radiology meetings. The purpose of this study is to quantitatively and qualitatively evaluate the use of Twitter as a microblogging platform at recent RSNA annual meetings. Methods Twitter activity meta-data tagged with official meeting hashtags #RSNA11 and #RSNA12 were collected and analyzed. Multiple metrics were evaluated, including daily and hourly Twitter activity, frequency of microblogging activity over time, characteristics of the 100 most active Twitter users at each meeting, characteristics of meeting-related tweets, and the geographic origin of meeting microbloggers. Results The use of Twitter microblogging increased by at least 30% by all identifiable meaningful metrics between the 2011 and 2012 RSNA annual meetings, including total tweets, tweets per day, activity of the most active microbloggers, and total number of microbloggers. Similar increases were observed in numbers of North American and international microbloggers. Conclusion Markedly increased use of the Twitter microblogging platform at recent RSNA annual meetings demonstrates the potential to leverage this technology to engage meeting attendees, improve scientific sessions, and promote improved collaboration at national radiology meetings.

TL;DR: This Secret History documentary follows experts as they pick through the evidence and reveal why the plague killed on such a scale, and what might be coming next.
Abstract: Secret History: Return of the Black Death Channel 4, 7-8pm In 1348 the Black Death swept through London, killing people within days of the appearance of their first symptoms. Exactly how many died, and why, has long been a mystery. This Secret History documentary follows experts as they pick through the evidence and reveal why the plague killed on such a scale. And they ask, what might be coming next?

TL;DR: Clinicians should be prepared to offer patients a choice between a screening test that is effective at both early cancer detection and cancer prevention through the detection and removal of polyps and those that can detect cancer early and also can detect adenomatous polyps.
