ractice.Since their introduction into clinical practice in the 1950s, ileal conduits have been the most common type of urinary diversion used after radical cystectomy worldwide. Although ileal conduits are technically simpler to construct than other forms of urinary diversion, a variety of complications can occur in the early and late postoperative periods. Early complications include urine leakage, urinary obstruction, postoperative fluid collection (eg, urinoma, hematoma, lymphocele, or abscess), and fistula formation. Late complications include ureteroileal anastomotic stricture, stomal stenosis, conduit stenosis, and urolithiasis. this website Although not directly related to ileal conduits, ureteroarterial fistula can occur in patients with an ileal conduit. Interventional radiologists can play a pivotal role in diagnosis and management of these complications by performing image-guided minimally invasive procedures. In this article, the authors review the surgical anatomy of an ileal conduit and the underlying pathophysiology of and diagnostic workup for complications related to ileal conduits. The authors also discuss and illustrate current approaches to interventional radiologic management of these complications, with emphasis on a collaborative approach with urologists or endourologists to best preserve patients' renal function and maintain their quality of life. ©RSNA, 2020.Gallbladder carcinoma is the most common cancer of the biliary system. It is challenging to diagnose because patients are often asymptomatic or present with nonspecific symptoms that mimic common benign diseases. Surgical excision is the only curative therapy and is best accomplished at early non-locally advanced stages. Unfortunately, gallbladder cancer often manifests at late locally advanced stages, precluding cure. Early tumors are often incidentally detected at imaging or at cholecystectomy performed for another indication. Typical imaging features of localized disease include asymmetric gallbladder wall thickening, polyps larger than 1.0 cm, and a solid mass replacing the gallbladder lumen. Advanced tumors are often infiltrative and can be confusing at CT and MRI owing to their large size. Determination of the origin of the lesion is paramount to narrow the differential diagnosis but is often challenging. It is important to identify gallbladder cancer and distinguish it from other benign and malignant hepatobiliary processes. Since surgical resection is the only curative treatment option, radiologist understanding and interpretation of pathways of nodal and infiltrative tumor spread can direct surgery or preclude patients who may not benefit from surgery. While both CT and MRI are effective, MRI provides superior soft-tissue characterization of the gallbladder and biliary tree and is a useful imaging tool for diagnosis, staging, and evaluation of treatment response. ©RSNA, 2020.Background Multiple modifiable lifestyle factors are well-known contributors to many health problems. Objectives This study aims to determine the association between latent class analysis (LCA) of modifiable lifestyle risk factors with being overweight and/or obese for children and/or adolescents. Methods Articles were selected from six databases, without limitation regarding language or date. The review included studies that identify latent classes of modifiable lifestyle risk factors [e.g., physical activity (PA), diet, sedentary behavior (SB), and/or unhealthy behavior] by LCA to determine the association between latent classes with being overweight and/or obese. The methodology of the selected studies was evaluated using the JBI Critical Appraisal Checklist for Analytical Cross-Sectional Studies. Owing to the heterogeneity between latent classes of modifiable lifestyle risk factors with obesity and/or being overweight, the results are described narratively. Results Using a selection process in two phases, nine articles were included. All of the included studies were of high methodological quality. The studies were conducted in six different countries the USA, Brazil, Canada, Portugal, Italy, and Australia. Sample sizes ranged from 166 to 18.587 children and adolescents, and in terms of age (range 5-19 years). Across study clusters characterized by low consumption of fruit and vegetables, and high consumption of fatty foods, sugar snack foods, sweets, chips and fries, low PA (2 hours/day), sleep time ( less then 10 hours/day) were positively associated with being overweight and/or obese. Conclusion Overall there is good evidence to support that the modifiable lifestyle risk factors clustered together by LCA should be novel targets for the treatment of obesity and its associated comorbidities.While SARS-CoV-2 primarily affects the lungs, the virus may be inflicting detriments to the cardiovascular system, both directly through angiotensin-converting enzyme 2 receptor and initiating systemic inflammation. Persistent systemic inflammation may be provoking vascular dysfunction, an early indication of cardiovascular disease risk. To establish the potential effects of SARS-CoV-2 on the systemic vasculature in the arms and legs, we performed a cross-sectional analysis of young healthy adults (control 5 M/15 F, 23.0 ± 1.3 y, 167 ± 9 cm, 63.0 ± 7.4 kg) and young adults who, 3-4 wk prior to testing, had tested positive for SARS-CoV-2 (SARS-CoV-2 4 M/7 F, 20.2 ± 1.1 y, 172 ± 12 cm, 69.5 ± 12.4 kg) (means ± SD). Using Doppler ultrasound, brachial artery flow-mediated dilation (FMD) in the arm and single passive limb movement (sPLM) in the leg were assessed as markers of vascular function. Carotid-femoral pulse wave velocity (PWVcf) was asvsessed as a marker of arterial stiffness. FMD was lower in the SARS-Corom this study were a strikingly lower vascular function and a higher arterial stiffness compared with healthy controls. Together, these results suggest rampant vascular effects seen weeks after contracting SARS-CoV-2 in young adults.In human heart failure and in murine hearts with left-ventricular pressure overload (LVPO), increases in fibrosis are associated with increases in myocardial stiffness. Secreted protein acidic and rich in cysteine (SPARC) is shown to be necessary for both cardiac fibrosis and increases in myocardial stiffness in response to LVPO; however, cellular sources of cardiac SPARC are incompletely defined. Irradiation and bone marrow transfer were undertaken to test the hypothesis that SPARC expression by bone marrow-derived cells is an important mediator of fibrosis in LVPO. In recipient SPARC-null mice transplanted with donor wild-type (WT) bone marrow and subjected to LVPO, levels of fibrosis similar to that of WT mice were found despite the lack of SPARC expression by resident cells. In recipient WT mice with donor SPARC-null bone marrow, significantly less fibrosis versus that of WT mice was found despite the expression of SPARC by resident cells. Increases in myocardial stiffness followed a similar pattern to that of collagen deposition.
