CT allows evaluation of the relationship with the pulmonary veins and other adjacent structures that can be injured during the procedure. CT also simulates procedural fluoroscopic angles and provides evaluation of the interatrial septum, which is punctured during LAA closure. CT also provides a more convenient method for the evaluation of postprocedural complications such as incomplete closure, peridevice leaking, device-related thrombus, and device dislodgement.

Most cases are the result of iatrogenic trauma, although accidental trauma and a variety of inflammatory, infectious, and neoplastic processes have also been implicated. Timely diagnosis can often be difficult, as the classic triad of upper GI hemorrhage, biliary colic, and jaundice is present in a minority of cases, and there may be considerable delay in the onset of bleeding after the initial injury. Therefore, the radiologist must maintain a high index of suspicion for this condition and be attuned to its imaging characteristics across a variety of modalities. CT is the first-line diagnostic modality in evaluation of hemobilia, while catheter angiography and endoscopy play vital and complementary roles in both diagnosis and treatment. The authors review the clinical manifestations and multimodality imaging features of hemobilia, describe the wide variety of underlying causes, and highlight key management considerations.©RSNA, 2021.Hemoptysis, which is defined as expectoration of blood from the alveoli or airways of the lower respiratory tract, is an alarming clinical symptom with an extensive differential diagnosis. CT has emerged as an important noninvasive tool in the evaluation of patients with hemoptysis, and the authors present a systematic but flexible approach to CT interpretation. The first step in this approach involves identifying findings of parenchymal and airway hemorrhage. The second step is aimed at determining the mechanism of hemoptysis and whether a specific vascular supply can be implicated. Hemoptysis can have primary vascular and secondary vascular causes. Primary vascular mechanisms include chronic systemic vascular hypertrophy, focally damaged vessels, a dysplastic lung parenchyma with systemic arterial supply, arteriovenous malformations and fistulas, and bleeding at the capillary level. Evaluating vascular mechanisms of hemoptysis at CT also entails determining if a specific vascular source can be implicated. Although the bronchial arteries are responsible for most cases of hemoptysis, nonbronchial systemic arteries and the pulmonary arteries are important potential sources of hemoptysis that must be recognized. Secondary vascular mechanisms of hemoptysis include processes that directly destroy the lung parenchyma and processes that directly invade the airway. Understanding and employing this approach allow the diagnostic radiologist to interpret CT examinations accurately in patients with hemoptysis and provide information that is best suited to directing subsequent treatment. ©RSNA, 2021. To determine patient and disease characteristics associated with functional disability among adults with advanced non-small-cell lung cancer (NSCLC). In a prospective cohort of participants newly diagnosed with advanced NSCLC and beginning systemic treatment, functional disability in usual activities, mobility, and self-care was measured using the EuroQol-5D-5L at baseline. Demographics, comorbidities, brain metastases, Eastern Cooperative Oncology Group performance status (ECOG PS), and psychologic variables (depression [Patient Health Questionnaire-9] and anxiety [Generalized Anxiety Disorder 7-item scale]) were captured. Patients were classified into two disability groups (none-slight or moderate-severe) on the basis of total functional status scores. Differences between disability groups were determined (chi-square and tests). Associations between patient characteristics and baseline disability were assessed using logistic regression. Among 173 participants, mean age was 63.3 years, 56% were malevanced NSCLC have moderate-severe functional disability at baseline. Psychologic symptoms were significantly associated with moderate-severe baseline disability.Although generic drugs are typically inexpensive, rising prices among some generic drugs in recent years have raised concern. Using Medicaid data, we found that one in five generic drugs sold in the US experienced a price spike (defined as a doubling in price over the course of one year) initiated by at least one manufacturer during the period 2014-17. There was a trend toward fewer price spikes each year, from 7.8 percent of drugs in 2014 to 5.8 percent in 2017. Among drugs experiencing price spikes, 51 percent were injected products, 64 percent had three or fewer manufacturers, and 18 percent were in shortage at the time of the spike. Generic drug price spikes cost Medicaid $1.5 billion during 2014-16, representing 4.2 percent of all Medicaid generic drug spending in that period. The trend toward fewer price spikes over time may be due to increased public scrutiny and regulatory actions. However, price spikes can be very costly, and additional policies are needed to both ensure adequate competition and control prices among generic drugs.Private equity firms have increasingly acquired physician practices, and particularly dermatology practices. https://www.selleckchem.com/products/Triciribine.html Analyzing commercial claims from the Health Care Cost Institute (2012-17), we used a difference-in-differences design within an event study framework to estimate the prevalence of private equity acquisitions and their impact on dermatologist prices, spending, utilization, and volume of patients. By 2017 one in eleven dermatologists practiced in a private equity-owned practice, and private equity-owned practices employed four advanced practitioners for every ten dermatologists compared with three for non-private equity practices. Private equity firms targeted their acquisitions at larger practices that saw more commercially insured patients compared with practices that were never acquired by private equity firms. The volume of patients per private equity dermatologist ranged from 4.7 percent to 17.0 percent higher than the volume per non-private equity dermatologist up to nine quarters after acquisition.
