The objective of this paper is to give an approach to tackle forearm access when there appears to be no palpable radial pulse. Preservation of radial flow is paramount while alternative forearm means to vascular access may help avoid the need to access the femoral artery. PMID: 31710251 [PubMed - as supplied by publisher]

We report on the prespecified secondary outcome, echocardiographic indexes of LV function, from a previously reported study of the effect of lung ultrasound (US)-guided dry weight reduction on systolic blood pressure.Study DesignSingle-blind randomized trial.Settings &Participants71 clinically euvolemic hypertensive hemodialysis patients in Greece and Slovenia.InterventionThe active intervention group’s (n = 35) volume removal was guided by the total number of lung US B-lines observed every week before a midweek dialysis session. The usual-care group (n = 36) was treated using standard-of-care...

This study is registered with the Netherlands Trial Registry, number NTR5263.FindingsWe screened patients for enrolment between Dec 3, 2015, and May 31, 2018. Patients completed baseline visits and started treatment between Dec 14, 2015, and July 2, 2018, and the last study visit of the last patient was Oct 4, 2018. Of 149 patients assessed for eligibility, 57 (38%) patients were excluded (predominantly because they did not meet one or several inclusion criteria, most often because of an absence of synovial inflammation or of flare-ups after NSAID washout) and 92 (62%) patients were eligible for inclusion. We randomly assi...

Background: Life expectancy of HIV patients has increased considerably as a result of antiretroviral therapy (ART), and cardiovascular (CV) disease has emerged as an important late concern. People with HIV infection could have an impaired systolic function; however data on diastolic function and markers of CV risk, such as epicardial adipose tissue (EAT) and intima-media thickness (IMT), are lacking. Aim of this study is to evaluate left ventricular function, EAT, and IMT in children and adolescents with vertically acquired HIV infection. Methods: We enrolled 29 subjects on ART (13, 45% men; median age of 13.0, and in...

Authors: Dai C, Li J, Li QM, Guo X, Fan YY, Qin HY Abstract PURPOSE: To compare the effect of tunneled and nontunneled peripherally inserted central catheter placement under B-mode ultrasound. METHODS: A single center, randomized, controlled, nonblinded, prospective trial was conducted in Guangzhou, China, between July 2018 and May 2019. A total of 174 participants were randomized to the experimental group (tunneled peripherally inserted central catheter) or the control group (nontunneled peripherally inserted central catheter) and were followed until extubation. Basic characteristics, peripherally inserted cen...
