Intra-Aneurysmal High-Resolution 4D MR Flow Imaging for Hemodynamic Imaging Markers in Intracranial Aneurysm Instability [RESEARCH]

BACKGROUND AND PURPOSE:

Prediction of aneurysm instability is crucial to guide treatment decisions and to select appropriate patients with unruptured intracranial aneurysms (IAs) for preventive treatment. High-resolution 4D MR flow imaging and 3D quantification of aneurysm morphology could offer insights and new imaging markers for aneurysm instability. In this cross-sectional study, we aim to identify 4D MR flow imaging markers for aneurysm instability by relating hemodynamics in the aneurysm sac to 3D morphologic proxy parameters for aneurysm instability.

MATERIALS AND METHODS:

In 35 patients with 37 unruptured IAs, a 3T MRA and a 7T 4D MRI flow scan were performed. Five hemodynamic parameters—peak-systolic wall shear stress (WSSMAX) and time-averaged wall shear stress (WSSMEAN), oscillatory shear index (OSI), mean velocity, and velocity pulsatility index—were correlated to 6 3D morphology proxy parameters of aneurysm instability—major axis length, volume, surface area (all 3 size parameters), flatness, shape index, and curvedness—by Pearson correlation with 95% CI. Scatterplots of hemodynamic parameters that correlated with IA size (major axis length) were created.

RESULTS:

WSSMAX and WSSMEAN correlated negatively with all 3 size parameters (strongest for WSSMEAN with volume (r = –0.70, 95% CI –0.83 to –0.49) and OSI positively (strongest with major axis length [r = 0.87, 95% CI 0.76–0.93]). WSSMAX and WSSMEAN correlated positively with shape index (r = 0.61, 95% CI 0.36–0.78 and r = 0.49, 95% CI 0.20–0.70, respectively) and OSI negatively (r = –0.82, 95% CI –0.9 to –0.68). WSSMEAN and mean velocity correlated negatively with flatness (r = –0.35, 95% CI –0.61 to –0.029 and r = –0.33, 95% CI –0.59 to 0.007, respectively) and OSI positively (r = 0.54, 95% CI 0.26–0.74). Velocity pulsatility index did not show any statistically relevant correlation.

CONCLUSIONS:

Out of the 5 included hemodynamic parameters, WSSMAX, WSSMEAN, and OSI showed the strongest correlation with morphologic 3D proxy parameters of aneurysm instability. Future studies should assess these promising new imaging marker parameters for predicting aneurysm instability in longitudinal cohorts of patients with IA.

PD-L1+ diffuse large B-cell lymphoma with extremely high mutational burden and microsatellite instability due to acquired PMS2 mutation [RESEARCH REPORT]

We present a unique case of a single patient presenting with two mutationally distinct, PD-L1+ diffuse large B-cell lymphomas (DLBCLs). One of these DLBCLs demonstrated exceptionally high mutational burden (eight disease-associated variants and 41 variants of undetermined significance) with microsatellite instability (MSI) and an acquired PMS2 mutation with loss of PMS2 protein expression, detected postchemotherapy. This report, while highlighting the extent of possible tumor heterogeneity across separate clonal expansions as well as possible syndromic B-cell neoplasia, supports the notion that, although rare, PD-L1 expression and associated states permissive of high mutational burden (such as mismatch repair gene loss of function/MSI) should be more routinely considered in DLBCLs. Appropriate testing may be predictive of outcome and inform the utility of targeted therapy in these genetically diverse and historically treatment-refractory malignancies.

BBC Arabic and the complexities of the Arab world

By Faris Couri, editor of the BBC Arabic Service


It is no secret that recent Arab uprisings have placed enormous burdens on the shoulders of BBC Arabic journalists responsible for reporting news from the region.

Covering the Arab world is not always an easy task - we need to mix sensible caution with a dose of courage in covering political issues that attract so many disputed views among Arabic-speaking audiences.

Our guiding principles are the BBC's values, its editorial guidelines, its ethical code, which are our reference points to maintain impartial, balanced and accurate reporting.

Across the Arab world - whether it's Tunisia, Yemen, Egypt or Libya, Bahrain, Syria and Iraq or the many other countries in the region - we know that audiences want access to objective and independent news, far removed from an agenda that favours one party, religion or sect against another. That is why audiences are turning to BBC Arabic.

Last year, our latest figures show that overall audiences to BBC Arabic have risen by more than 17% to a record high of 25.3 million adults weekly. That includes a big surge of 2.9 million in Saudi Arabia and 2.7 million in Egypt, where TV viewers in particular turned to the BBC to better understand the events happening in their own country. Our radio audiences are also holding up despite the reductions in transmission. Online is proving to be more of a challenge, but we are working hard to understand the needs of digital audiences and those for whom social media plays an increasingly important part in their lives.

In 2011, following the fall of the Mubarak leadership, we watched as ordinary Egyptians carried banners saying "Thank you, BBC!" But meeting the high expectation of audiences has a price and sometimes it's been a heavy one.

March 2011 brought a strong reminder of the risks that our staff face in covering the news - one of our reporters was arrested and tortured by Muammar Gaddafi's forces during the Libya uprising. In early 2012, our reporter in Yemen was beaten and received death threats from supporters of the outgoing president.

We are also challenged by those who disagree with our coverage. In countries such as Syria and Bahrain, BBC Arabic has been accused of bias.

The criticism comes from opposition and government alike. It may be a valid argument to say that getting criticism from both sides, in the case of Arab world certainly, is an indication of balanced coverage.

On Syria, for example, we had a series of documentaries looking at the civil war from a number of perspectives.

The first one, exploring what it's like to work for a Syrian television channel that's the mouthpiece of the government, was the butt of criticism and threats from Syrian opposition quarters. We followed it up with a programme charting a day in the lives of six Syrian women, five of whom were anti-government activists.

In our day-to-day news coverage, presenting a variety of voices from Syria is essential to us. And that is what distinguishes BBC Arabic from many media outlets in the Arab world which promote political views and agendas, and that is what we are determined to keep.

BBC Arabic marked its 75th anniversary in January. Arab politicians and ordinary people have expressed their appreciation of our track record of impartiality and trusted news. I am confident that the coming years will see further achievement on all our platforms - TV, radio and online.
