Is trans-radial approach related to an increased risk of radiation exposure in patients who underwent diagnostic coronary angiography or percutaneous coronary intervention? (The SAKARYA study)
Conclusion: In spite of an increased experience with trans-radial approach, PCI of coronary lesions via radial route was associated with a relatively small but significant radiation exposure in our study. Compared to femoral access, diagnostic CA via radial access was not related to an increased radiation exposure
Crizotinib efficacy and safety in patients with advanced NSCLC harboring MET alterations: A real-life data of Turkish Oncology Group
Crizotinib is a multikinase inhibitor, effective in non-small cell lung cancer (NSCLC) harboring mesenchymal-epidermal transition (MET) alterations. Although small prospective studies showed efficacy and safety of crizotinib in NSCLC with MET alterations, there is limited real-life data. Aim of this study is to investigate real-life efficacy and safety of crizotinib in patients with advanced NSCLC harboring MET alterations. This was a retrospective, multicenter (17 centers) study of Turkish Oncology Group. Patients' demographic, histological data, treatment, response rates, survival outcomes, and toxicity data were collected. Outcomes were presented for the study population and compared between MET alteration types. Total of 62 patients were included with a median age of 58.5 (range, 26-78). Major histological type was adenocarcinoma, and 3 patients (4.8%) had sarcomatoid component. The most common MET analyzing method was next generation sequencing (90.3%). MET amplification and mutation frequencies were 53.2% (n = 33) and 46.8% (n = 29), respectively. Overall response rate and disease control rate were 56.5% and 74.2% in whole study population, respectively. Median progression free survival (PFS) was 7.2 months (95% confidence interval [CI]: 3.8-10.5), and median overall survival (OS) was 18.7 months (95% CI: 13.7-23.7), regardless of treatment line. Median PFS was 6.1 months (95% CI: 5.6-6.4) for patients with MET amplification, whereas 14.3 months (95% CI: 6.7-21.7) for patients with MET mutation (P = .217). Median PFS was significantly longer in patients who have never smoked (P = .040), have good performance score (P < .001), and responded to the treatment (P < .001). OS was significantly longer in patients with MET mutation (25.6 months, 95% CI: 15.9-35.3) compared to the patients with MET amplification (11.0 months; 95% CI: 5.2-16.8) (P = .049). In never-smokers, median OS was longer than smoker patients (25.6 months [95% CI: 11.8-39.3] vs 16.5 months [95% CI: 9.3-23.6]; P = .049). The most common adverse effects were fatigue (50%), peripheral edema (21%), nausea (29%) and diarrhea (19.4%). Grade 3 or 4 adverse effects were observed in 6.5% of the patients. This real-life data confirms efficacy and safety of crizotinib in the treatment of advanced NSCLC harboring MET alteration

Abused android permissions by advertising networks
Android is the leading mobile operating system for smart phone and mobile tablet platforms. Since these mobile devices contain personal and sensitive data, security is a big challenge for them. Even though various security features are supported by Android, its permission model is quite problematic from usability and privacy aspects. When users want to install an application, they must grant all requested permissions. Since manually checking dozens of permissions is cumbersome, users ignore it and accept permissions without reading them. In Google Play Store, there exist thousands of applications that request more permissions than they actually need. Applications with unnecessary permissions can misuse their permissions and endanger their users' security and privacy. Especially, advertising network libraries, integrated within applications, request many unnecessary permissions and get unauthorized access to users' personal data. In this paper, we explain the results of our study which analyzes several advertising networks, their permission requests and behavior for accessing critical resources.IEEEIEEE Computer SocietyInst Creative Advanced Technologies Sci & EngnUniversity of Science and Technology BeijingKyonggi UniversityKorea Ind Security ForumKorean Convergence Security Asso

Moderate sedation in cardiac electrophysiology laboratory: a retrospective safety analysis
Acute pancreatitis linked to bevacizumab: A case report
Introduction: The monoclonal anti-vascular endothelial growth factor antibody bevacizumab is increasingly being used in the treatment of malignant tumors. It is the first molecular-targeted agent used in the treatment of several ovarian cancers. The typical side effects of this drug are hypertension and proteinuria. Bevacizumab-related acute pancreatitis (AP) has not been described before, but AP associated with other chemotherapeutic agents has been reported. Research has shown that patients can develop AP when taking sorafenib, a multiple tyrosine kinase inhibitor that inhibits VEGF. Case presentation: We explored the case of a 48-year-old woman who presented with undefined upper abdominal pain after receiving a cisplatin-gemcitabine-bevacizumab combination treatment as second-line therapy for metastatic ovarian cancer. Our patient was hospitalized because of AP after two cycles of this treatment. The patient started experiencing abdominal pain after the first course of chemotherapy. The severity and duration of this pain increased after the second cycle of chemotherapy. Her abdominal pain and elevated serum amylase disappeared when treated by chemotherapy without bevacizumab; this also improved her clinical pancreatitis. Conclusions: AP without other etiological factors can occur in patients treated by chemotherapy. Furthermore, bevacizumab might induce the side effects of AP
Automated generation of attack graphs using NVD
8th ACM Conference on Data and Application Security and Privacy (2018 : Tempe; United States)Today’s computer networks are prone to sophisticated multi-step, multi-host attacks. Common approaches of identifying vulnerabilities and analyzing the security of such networks with naive methods such as counting the number of vulnerabilities, or examining the vulnerabilities independently produces incomprehensive and limited security assessment results. On the other hand, attack graphs generated from the identified vulnerabilities at a network illustrate security risks via attack paths that are not apparent with the results of the primitive approaches. One common technique of generating attack graphs requires well established definitions and data of prerequisites and postconditions for the known vulnerabilities. A number of works suggest prerequisite and postcondition categorization schemes for software vulnerabilities. However, generating them in an automated way is an open issue. In this paper, we first define a model that evolves over the previous works to depict the requirements of exploiting vulnerabilities for generating attack graphs. Then we describe and compare the results of two different novel approaches (rule-based and machine learning-employed) that we propose for generating attacker privilege fields as prerequisites and postconditions from the National Vulnerability Database (NVD) in an automated way. We observe that prerequisite and postcondition privileges can be generated with overall accuracy rates of 88,8 % and 95,7 % with rule-based and machine learning-employed (Multilayer Perceptron) models respectively.ACM SIGSA
