The clinical outcomes of major bleeding events following ultrasound-guided native and allograft parenchymal renal biopsy were evaluated. Forty-eight bleeding complications after biopsy (Society of Interventional Radiology adverse event grade ≥ 2) from 2002 to 2018 were identified. The primary outcome assessed was renal function. The clinical outcomes and interventions performed, including blood transfusion, angiography with or without embolization, nephrostomy tube placement, surgery, nephrectomy, hospitalization, intensive care unit admission, dialysis, and survival, were noted. Renal function may be moderately diminished in the short-term periprocedural setting. None of the patients studied died or required nephrectomy or the initiation of dialysis as a result of a major bleeding complication after the renal biopsy. 相似文献

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been reported as a global emergency. As respiratory dysfunction is a major clinical presentation of COVID-19, chest computed tomography (CT) plays a central role in the diagnosis and management of patients with COVID-19. Recent advances in imaging approaches using artificial intelligence have been essential as a quantification and diagnostic tool to differentiate COVID-19 from other respiratory infectious diseases. Furthermore, cardiovascular involvement in patients with COVID-19 is not negligible and may result in rapid worsening of the disease and sudden death. Cardiac magnetic resonance imaging can accurately depict myocardial involvement in SARS-CoV-2 infection. This review summarizes the role of the radiology department in the management and the diagnosis of COVID-19, with a special emphasis on ultra-high-resolution CT findings, cardiovascular complications and the potential of artificial intelligence. 相似文献

ABSTRACTSpousal caregivers draw upon understandings of shifting relationality to maintain a familial understanding of their spouse with Alzheimer’s disease. Working through what it means to think of an adult with Alzheimer’s disease “like a child,” I trace how spouses negotiate their shifting relationships across the course of Alzheimer’s. While regarding adults as childlike can be perceived as dehumanizing infantilization, for families living with Alzheimer’s disease, conceiving of one’s spouse as like a child can actually enable processes of continued care, sustained recognition, and love to uphold personhood in the midst of often radical change. 相似文献
