Health-related Quality of Life in Children and Adolescents with Sagittal Synostosis

Background: This study evaluated the health-related quality of life (HR-QoL) in patients with sagittal synostosis (SS), and the influence of frequent headaches and surgical techniques on the HR-QoL. Method: Patients with SS aged 8 to 18 years were invited to participate between June 2016 and February 2017. The Child Health Questionnaire was used to assess the HR-QoL. A detailed questionnaire was used to assess the severity of headache symptoms. The control group consisted of 353 school children aged 5 to 14 years. Results: In all, 95 parents of patients with SS were invited to participate, of whom 68 (71.6%) parents completed the CHQ-PF50. The mean age of the participating patients was 12.4 years (10.8 to 14.2). The Psychosocial-and Physical summary of the patients with SS was similar to the general population. In the distinct CHQ scales, "Family cohesion" (P=0.02) was higher, and "Mental health" (P=0.05) was lower compared with the general population. The type and timing of surgery did not affect the HR-QoL. Thirty-two patients (47.1%) reported having headache complaints at least once a month. The CHQ scores of SS patients with frequent headaches had a significantly lower score of mild to large effect than those without headaches. Conclusion: Patients with SS have a slightly lower to similar HR-QoL compared with the general population. In all, 47.1% of SS patients have frequent headaches, resulting in lower average HR-QoL. The type and timing of surgery did not affect the results. Clinicians should be aware of lower HR-QoL in some subgroups of patients with SS.</p

Does early resection of presumed low-grade glioma improve survival? A clinical perspective

Early resection is standard of care for presumed low-grade gliomas. This is based on studies including only tumors that were post-surgically confirmed as low-grade glioma. Unfortunately this does not represent the clinicians’ situation wherein he/she has to deal with a lesion on MRI that is suspect for low-grade glioma (i.e. without prior knowledge on the histological diagnosis). We therefore aimed to determine the optimal initial strategy for patients with a lesion suspect for low-grade glioma, but not histologically proven yet. We retrospectively identified 150 patients with a resectable presumed low-grade-glioma and who were otherwise in good clinical condition. In this cohort we compared overall survival between three types of initital treatment strategy: a wait-and-scan approach (n = 38), early resection (n = 83), or biopsy for histopathological verification (n = 29). In multivariate analysis, no difference was observed in overall survival for early resection compared to wait-and-scan: hazard ratio of 0.92 (95% CI 0.43–2.01; p = 0.85). However, biopsy strategy showed a shorter overall survival compared to wait-and-scan: hazard ratio

Comparison of eligible non-enrolled patients and the randomised TWENTE trial population treated with Resolute and XIENCE V drug-eluting stents

Aims: The TWENTE trial recently enrolled more than 80% of all eligible patients, who were randomised to zotarolimus-eluting Resolute or everolimus-eluting XIENCE V stents. In the present study, we investigated whether eligible, non-enrolled patients differed from the randomised TWENTE trial population in baseline characteristics and one-year outcome. Methods and results: Characteristics of 1,709 eligible patients were analysed. Independent external adjudication of clinical events was likewise performed for non-enrolled (n=318) and randomised patients (n=1,391). Non-enrolled and randomised patients did not differ in gender distribution, diabetes mellitus, and clinical presentation, but differed significantly in age and cardiovascular history. Nevertheless, clinical outcome after one year did not differ in the primary composite endpoint target-vessel failure (TVF; 9.8% vs. 8.1%; p=0.34), and its components cardiac death (1.6% vs. 1.2%; p=0.61), target vessel-related myocardial infarction (4.7% vs. 4.6%; p=0.92), and target-vessel revascularisation (3.8% vs. 3.0%; p=0.48). Previous bypass surgery predicted TVF in non-enrolled patients (p=0.001); removal of these patients resulted in identical TVF rates for non-enrolled and randomised patients (7.3% vs. 7.3%; p=0.99). Conclusions: Despite some differences in baseline characteristics, non-enrolled and randomised patients did not differ in one-year outcome, which was favourable for both populations and may be related to the drug-eluting stents used

A Randomized Controlled Trial in Second-Generation Zotarolimus-Eluting Resolute Stents Versus Everolimus-Eluting Xience V Stents in Real-World Patients : The TWENTE Trial

ObjectivesThe aim of this study was to compare the safety and efficacy of Resolute zotarolimus-eluting stents (ZES) (Medtronic Cardiovascular, Santa Rosa, California) with Xience V everolimus-eluting stents (EES) (Abbott Vascular Devices, Santa Clara, California) at 1-year follow-up.BackgroundOnly 1 randomized trial previously compared these stents.MethodsThis investigator-initiated, patient-blinded, randomized noninferiority study had limited exclusion criteria (acute ST-segment elevation myocardial infarctions not eligible). Patients (n = 1,391; 81.4% of eligible population) were randomly assigned to ZES (n = 697) or EES (n = 694). Liberal use of stent post-dilation was encouraged. Cardiac biomarkers were systematically assessed. The primary endpoint was target vessel failure (TVF), a composite of cardiac death, myocardial infarction not clearly attributable to non-target vessels, and clinically indicated target-vessel revascularization. An external independent research organization performed clinical event adjudication (100% follow-up data available). Analysis was by intention-to-treat.ResultsAcute coronary syndromes were present in 52% and “off-label” feature in 77% of patients. Of the lesions, 70% were type B2/C; the post-dilation rate was very high (82%). In ZES and EES, TVF occurred in 8.2% and 8.1%, respectively (absolute risk-difference 0.1%; 95% confidence interval: −2.8% to 3.0%, pnoninferiority = 0.001). There was no significant between-group difference in TVF components. The definite-or-probable stent thrombosis rates were relatively low and similar for ZES and EES (0.9% and 1.2%, respectively, p = 0.59). Definite stent thrombosis rates were also low (0.58% and 0%, respectively, p = 0.12). In EES, probable stent thrombosis beyond day 8 was observed only in patients not adhering to dual antiplatelet therapy.ConclusionsResolute ZES were noninferior to Xience V EES in treating “real-world” patients with a vast majority of complex lesions and “off-label” indications for drug-eluting stents, which were implanted with liberal use of post-dilation.

TCT-47 Two-Year Clinical Outcome of the TWENTE Trial, a Randomized Controlled Trial Comparing Second-Generation Zotarolimus-Eluting Resolute Stents Versus Everolimus-Eluting Xience V Stents in Real-World Patients

Background: In the prospective, randomized TWENTE trial, the zotarolimus-eluting Resolute stent was at 1 year follow-up non-inferior to the everolimus-eluting Xience V stent for the primary endpoint target vessel failure. This composite endpoint consisted of cardiac death, clinically indicated target vessel revascularization, or target vessel-related myocardial infarction (MI). So far, few long-term data of prospective head-to-head comparisons between both DES have been reported. Methods: Patients requiring percutaneous coronary interventions (PCI) with DES implantation at Thoraxcentrum Twente in Enschede were randomization between Resolute (Medtronic Vascular, Santa Rosa, CA, USA) and Xience V (Abbott Vascular, Santa Clara, CA, USA) in a 1:1 fashion. Inclusion of all coronary or bypass graft lesions and all clinical settings was permitted except for primary PCI (i.e. acute ST-elevation myocardial infarction (STEMI) was an exclusion criterion). Both external monitoring and clinical event adjudication were performed by an independent external contract research organization (Cardialysis, Rotterdam, the Netherlands). Two year clinical follow-up was performed as indicated in the study protocol. Results: A total of 1,391 patients were enrolled in the TWENTE trial between June 2008 and August 2010. The study population comprised 21.6% diabetics with a vast majority of complex lesions and “off-label” indications for drug-eluting stents (77.4%). Patients presented with either stable angina (48.5%) or unstable angina/Non-STEMI (51.5%). Demographics, baseline angiographic and procedural data, and 2-year clinical follow-up data will be presented. This includes the primary endpoint of the study: Target vessel failure (TVF) at 2 year follow-up. Secondary endpoints include the individual components of the primary endpoint and the incidence of very late stent thrombosis. In addition, results of subgroup analyses will be reported. Conclusions: Results of pre-specified analyses of 2-year clinical outcome of the TWENTE trial will be presented at TCT 2012

Clinical evaluation of a dedicated next generation sequencing panel for routine glioma diagnostics

Since 2013 next-generation sequencing (NGS) targeting genes mutated in diffuse gliomas is part of routine diagnostics in our institute. In the present report, we evaluate the use of this custom tailored NGS platform on 434 samples. The NGS panel assesses mutations in ATRX, CIC, EGFR, FUBP1, NOTCH1, PTEN; H3F3A, IDH1/2, PIK3CA, and BRAF, amplifications in EGFR or MDM2 and copy number alterations (CNA) of chromosome 1p, 7, 10 and 19q. TERT promoter mutations were assessed separately when indicated. Of the 433 samples of individual tumors with NGS data available, 176 cases were diagnosed as grade 2 or 3 glioma (40.6) and in 201 patients a glioblastoma (46.4%). Of the remaining 56 patients, 22 had inconclusive histology. In 378 cases (87.1%) a diagnosis solely based on glioma-targeted NGS could be established and resulted in a different diagnosis in ~ 1/4 of the cases. In 17 out of 22 cases without a conclusive histological diagnosis NGS resulted in a molecular diagnosis.The current study on a large cohort of patients confirms the diagnostic strength of the platform we developed, with a clear separation of glioma subgroups with different outcomes. It demonstrates the diagnostic value and the efficiency of glioma-targeted NGS for routine glioma diagnostics allowing with a single assay a glioma diagnosis in the large majority of cases. It allows in one run the molecular assessments required for the WHO classification of diffuse gliomas, including the recent recommendations to assess copy number alterations of chromosome 7 and 10, and of the TERT promoter region in IDHwt lower grade glioma

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results
