In recent decades, endovascular approaches have become the standard treatment for most tentorial dural arteriovenous fistulas (TDAVFs). buy MPTP Although endovascular treatment (EVT) is associated with better clinical outcomes, the angiographic occlusion rates are lower than those of surgical or combined approaches.

To evaluate the efficacy and safety of EVT for TDAVFs using the transarterial approach (TAA) as a first-line strategy.

Clinical and radiological data from 45 consecutive patients with TDAVFs who underwent EVT at 2 centers were retrospectively reviewed. Patient demographics and clinical and angiographic data were registered. Postprocedural and 6-mo follow-up angiographic and clinical results were evaluated. Univariable and multivariable logistic regression were performed to identify angiographic occlusion predictors after the first session and predictors of clinical complications.

An isolated TAA was used for 40 TDAVFs (88.9%). A total of 37 (82.2%) TDAVFs were completely occluded after a single EVT session, and 44 TDAVFs (97.8%) were completely occluded after the last procedure. The presence of fewer than 5 arterial feeders was a predictor for total occlusion after the first treatment session (odds ratio [OR], 18.9; 95% CI 2.06-173.57; P=.01). Six-month angiographic control was performed in 42 patients, and all TDAVFs were occluded. Good long-term neurological outcomes were observed in 41 patients (91.1%). Clinical complications occurred in 7 (15.6%) patients. They were related to the number of accessed arteries to perform TAA (odds ratio, 2.53; 95% CI 1.10-5.86; P=.03). The procedure-related mortality rate was 2.2%.

TAA is a safe and effective treatment for TDAVFs.

Paravalvular leakage (PVL) after transcatheter aortic valve replacement (TAVR) is a common complication in patients with bicuspid aortic valve (BAV). However, predictors and mechanisms of PVL are not well understood in this subset. The aim of this study was to analyse determinants and mechanisms of PVL in BAV and tricuspid aortic valve (TAV).

Of the 2394 consecutive patients undergoing transfemoral TAVR using new-generation valves at our centre, we identified 242 cases with BAV. To adjust for baseline differences, we performed 3  1 propensity score matching (TAVPS n = 726). We analysed the aortic root anatomy and calcification as well as the number, circumferential distribution, and predilection sites of PVL using pre-procedural multidetector computed tomography and post-TAVR echocardiography. In the matched cohort, the incidence of PVL ≥mild (BAV 51.9% vs. TAVPS 51.7%; P = 0.955) and PVL ≥moderate (BAV 5.0% vs. TAVPS 3.7%; P = 0.393), the circumferential distribution, and independent predictors were similar between BAV and TAVPS. Both the presence of peri-annular calcium chunks or LVOT calcification were highly associated with PVL in BAV and TAVPS patients, whereas in BAV patients neither the presence of a calcium bridge nor the volume of its calcification was related to PVL. Notably, the spatial localization of these lesions did not necessarily match the circumferential leak position.

The incidence, circumferential distribution, predilection sites, and predictors of PVL were similar in matched population of BAV and TAVPS patients undergoing transfemoral TAVR using new-generation devices. These novel findings suggest a common underlying mechanism of PVL in both entities.

Short tandem repeat (STR)-based chimerism analysis has been widely used for chimerism monitoring after hematopoietic stem-cell transplantation (HSCT), but technical artifacts can be problematic. We designed a chimerism assay using single nucleotide polymorphisms (SNPs) adjacent and in linkage-disequilibrium (CASAL), which doubly checked for SNP pairs, and thus could reduce background errors and increase analytical sensitivity.

CASAL targeted 84 SNP pairs within 10 bp distance and in perfect linkage-disequilibrium. Using undiluted and serially diluted samples, baseline error rates, and linearity was calculated. Clinical performance of CASAL was evaluated in comparison with a conventional STR assay, using 191 posttransplant samples from 42 patients with HSCT.

CASAL had ∼10 times lower baseline error rates compared to that of ordinary next-generation sequencing. Limit of detection and quantification of CASAL were estimated to be 0.09 and 0.39%, respectively, with a linear range of 0.1-100%. CASAL correlated well with STR assay (r2 = 0.99) and the higher sensitivity enabled detection of low-level recipient chimerism and earlier prediction of relapse.

CASAL is a simple, analytically sensitive and accurate assay that can be used in clinical samples after HSCT with a higher performance compared to that of traditional assays. It should also be useful in other forensic and archeological testing.

To describe the usefulness of an innovative "semi-real-time" pharmacy dashboard in managing workload during the unpredictable coronavirus disease 2019 (COVID-19) pandemic.

We created a pharmacy dashboard to monitor workload and key performance indicators during the dynamic COVID-19 crisis. The dashboard accessed the prescribing workload from our clinical information system and filled prescriptions from robotic prescription dispensing systems. The aggregated data was visualized using modern tools. The dashboard presents performance data in near real time and is updated every 15 minutes. After validation during the early weeks of the COVID-19 crisis, the dashboard provided reliable data and served as a great decision support aid in calculating the backlog of prescribed but unfilled prescriptions. It also aided in adjusting manpower, identifying prescribing and dispensing patterns, identifying trends, and diverting staff resources to appropriate locations. The dashboard has been useful in clearing the backlog in a timely manner, staff planning, and predicting the next coming surge so that we can proactively minimize accumulation of backlogged prescriptions.
