The discovery of Pre-RA has also underpinned the development of several clinical prevention trials in RA; specifically, the PRAIRI study demonstrated that a single dose of rituximab can delay the onset of clinically apparent IA in at-risk individuals. Additional studies are evaluating the ability of drugs including abatacept, hydroxychloroquine and methotrexate to prevent or delay future RA. SUMMARY The results from ongoing natural history and prevention trials in RA should further inform several critical issues in RA prevention including identification and enrolment of individuals at high-risk of imminent RA, the efficacy, safety and cost-effectiveness of prevention, and potentially the identification of new targets for prevention.PURPOSE OF REVIEW Musculoskeletal ultrasonography (MSUS) and magnetic resonance imaging (MRI) play important roles in diagnosis, monitoring, and prognostication of rheumatoid arthritis. This review highlights recent literature in this field and aims to provide insight into the future use in clinical practice. RECENT FINDINGS Recent studies concerning the use of MSUS and MRI in clinical practice show how MSUS and MRI can improve diagnosis and monitoring of rheumatoid arthritis and how they can predict both radiographic progression and clinical outcome (e.g., successful tapering of medical treatment). Moreover, novel technical developments of the two imaging modalities, such as 3D ultrasonography, ultrasound image reading with convolutional neural network, image fusion (MSUS and MRI) and whole-body MRI show promising results. Further validation of these novel techniques is required prior to implementation. SUMMARY MSUS and MRI will be important parts of the future management of rheumatoid arthritis patients, mostly because of their ability to detect rheumatoid arthritis changes at a very early stage and to predict the course of disease. However, the exact role in routine clinical practice is still to be defined.PURPOSE OF REVIEW As active rheumatic and musculoskeletal disease during pregnancy increases the risk for pregnancy loss, preterm birth, and maternal illness, ongoing management with pregnancy-compatible medications can improve these outcomes. Selecting and taking these medications can be challenging for rheumatologists and patients due to limited knowledge about potential risks and benefits. RECENT FINDINGS Fortunately, the American College of Rheumatology, American College of Obstetrics and Gynecology, British Rheumatology Society, and the European League Against Rheumatism have each published recommendations to guide the use of antirheumatic medications in pregnancy and lactation. Each of these groups endorsed the use of hydroxychloroquine, azathioprine, sulfasalazine, corticosteroids, NSAIDs, and tumor necrosis factor inhibitors in pregnancy. They also agreed that methotrexate, mycophenolate, cyclophosphamide, and leflunomide should be avoided in pregnancy. New medications, including small-molecules and biologics, have limited data to support safety in pregnancy and are not currently recommended during this period. Most antirheumatic medications are compatible with lactation. SUMMARY Because many patients are hesitant to use antirheumatic medications during pregnancy, honest and accurate discussions about pregnancy planning and management are important to help women make decisions that are in their and their offspring's best interest.Vascular remodeling is one of the most critical complications caused by hypertension. Previous studies have demonstrated that rosuvastatin has anti-inflammatory, antioxidant and antiplatelet effects and therefore can be used to treat cardiovascular disease. In this study, we explored the beneficial effects of rosuvastatin in reversing aortic remodeling in spontaneously hypertensive rats (SHR). After treating with different doses of rosuvastatin, its anti-lipid, anti-apoptosis and anti-inflammatory effects were determined. We also examined if rosuvastatin can improve the structure and function of the aorta. We found that rosuvastatin treatment of SHRs for two months at two different doses can effectively reduce the media thickness of the aorta compared with the control group. Similarly, rosuvastatin improved the vascular relaxation function of the aortic rings at a high level of acetylcholine in vitro. Mechanistically, it was found that rosuvastatin increased the expression of eNOS and plasma nitrite/nitrate levels. Besides, rosuvastatin suppressed the apoptosis and inflammation and up-regulated the expression of gap-junction complex connexin 43 both in media and endothelium. Lastly, rosuvastatin inhibited the AT1R/PKCα/HSP70 signaling transduction pathway. In summary, these findings demonstrated that rosuvastatin could improve the vascular structure and function mainly by increasing eNOS expression and preventing apoptosis and inflammation. This study provided evidence that rosuvastatin has beneficial effects in reversing the remodeling of the aorta due to hypertension.PURPOSE OF REVIEW Drug-induced liver injury (DILI) can be induced by a myriad of drugs. Assessing whether the patient has DILI and assessing which drug is the most likely culprit are challenging. There has been too little attention paid to the concept that certain drugs appear to have unique clinical features or 'phenotypes'. RECENT FINDINGS Several case series of DILI because of various drugs have been published, and analysis of these case series points to the fact that individual drugs have characteristic DILI signatures. These clinical phenotypes can be characterized by latency, biochemical features (R-value), as well as clinical symptoms and signs. Several drugs, including isoniazid, amoxicillin-clavulanic acid, anabolic steroids, β-interferon and others, have highly unique clinical features. Such unique properties may be able to be used to improve adjudication processes. SUMMARY Individual drugs have unique clinical DILI phenotypes or signatures. Furthermore, these may be able to be used to improve adjudication. In patients with aortic stenosis, the presence of hypertension negatively affects the hemodynamic severity of the stenosis, and worsens adverse left ventricular remodeling. It accelerates the progression of the stenosis and is associated with worse prognosis. Proper management of hypertension is thus crucial but there are concerns about the safety and efficacy of antihypertensive medications as well as uncertainty about optimal blood pressure (BP) targets and their impact on left ventricular mass regression and survival benefits. In the present review, we discuss these issues based on the evidence available in the current literature. E-616452 clinical trial Focus is first directed on the consequences of a persistently elevated BP before and after surgical aortic valve replacement or transcutaneous valve implantation, and the clinical significance of an abnormal BP response during exercise in patients with significant aortic stenosis. Available data on use of antihypertensive drugs are then critically addressed, the conclusion being that calcium channel blockers may be associated with lower survival, and that diuretics may have disadvantages in patients with left ventricular hypertrophy and smaller left ventricular cavity dimensions, β-blockers may be well tolerated and a better choice for patients with concomitant coronary artery disease and arrhythmias.
