An ontology based approach in health information systems: Blood test ontology example

<span>Health domain is a complex and distributed research area, where different institutions and people take and provide service, at the same time. Therefore, the health data about a patient is completely distributed among doctors, clinics, hospitals, pharmacies and insurance companies. To share and reuse the distributed, well-structured and semantically rich clinical data with the appropriate permissions from anywhere is one of the major areas that the research of information systems focused in healthcare domain in recent years. The semantic web provides a technological infrastructure with representing the meaning of data and reasoning new information from the existing knowledge for the healthcare domain. The blood, as the life fluid, gives hints to the clinicians about a patient's general health status by analyzing the ingredients in. The results of blood tests contain lots of information that can be used by different clinics. In the diagnostic phase, analyzing the blood for the same tests repeatedly delays to start the treatment process and increases the cost. The Blood Test Ontology is developed to model the blood tests semantically that is done in the health field and also to define information related with the blood and the blood tests as well as the relationships between them. The ontology in this work is developed with the aim to be used in the health information system, which should provide the querying, sharing and reusing the personalized the blood test result of the patients, as a knowledge base. The Blood Test Ontology is supported by the medical information standards to be able to interoperable with the other medical ontologies that are developed in the health.</span

Development of an Online Teaching Competency Scale for University Instructors

In providing effective online education, it is crucial that the instructors have the competence to teach online. The aim of this study is to develop a valid and reliable online teaching competency scale for online instructors. The data were collected from 392 instructors working in a big state university in Turkey (Istanbul University-Cerrahpasa). The instructors have conducted online courses through synchronous and asynchronous methods during the pandemic process. The development and evaluation process of the scale included exploratory factor analysis and convergent validity. The scale consists of 15 items and represents four factors of online instructors’ competencies: pedagogy, facilitation, technology, and course administration. The total variance of the scale was found 64%. Internal consistency coefficient of the whole scale was found to be .83 according to reliability analysis. The results of the study revealed that the scale is valid and reliable for measuring instructors’ online teaching competency. The implications of the study were discussed in detail

Duodenal Duplication Cyst with Recurrent Acute Pancreatitis: Report of a Case

Introduction:Duplication cyst can be occurred in any level of GI tract but the duodenal cysts are extremely rare. Most of the duplication cysts are detected in children. Duodenum duplication cysts are difficult to diagnose, as the presenting symptoms are nonspecific and are closely related to the type, size and location of the lesion. Both CT imaging and MRI can adequately identify a duodenal duplication cyst.Presentation of the case: We report an adult with recurrent episodes of acute pancreatitis who was diagnosed with ERCP. With the diagnosis of duodenal duplication cyst, we planned to perform surgical resection of the cyst.Conclusions: The surgical intervention for duodenal duplication cyst includes complete or partial surgical resection of the cyst. The location of the cysts in relation to the duodenum, especially to the ampulla, is important to determine the treatment strategy. Alternatively, duodenum duplication can be safely and effectively treated by different endoscopic interventions

Relationship between lymphovascular invasion and clinicopathological features of papillary thyroid carcinoma

Lymphovascular invasion (LVI) is an important prognostic factor in various solid tumors, however, data on the association between LVI and thyroid carcinomas are limited. In this study, we evaluated the relationship between LVI and clinicopathological features of papillary thyroid carcinoma (PTC). Six hundred seventy-eight patients diagnosed with PTC between 2012 and 2015 were included into the study. Patients were classified based on the presence or absence of LVI. Gender, age, ultrasonography (US), tumor size and multifocality, BRAFV600E mutation, perineural and capsular invasion, extrathyroid extension (ETE), nodal metastasis, and recurrences were evaluated, and risk analysis was performed for each parameter. The number of patients with LVI [LVI (+)] was 63, while the number of patients without LVI [LVI (-)] was 615. The female/male ratio was 564/114. LVI was present in 18.4% of male patients and in 7.4 % of female patients. In the age group between 17-25 years LVI was detected in 6/13 patients, and this result was statistically significant compared to other age groups (p = 0.004). Suspicious lymph nodes upon US, perineural or capsular invasion, ETE, tumor size, and nodal metastasis were significantly more frequent in LVI (+) group (p < 0.001). The frequency of BRAFV600E mutation was also significantly higher in LVI (+) group (p < 0.001). Overall, the presence of LVI was associated with gender, tumor size, age, lymph node metastasis, pathological lymph nodes, perineural and capsular invasion, ETE, and BRAFV600E mutation. These results suggest that in PTC patients undergoing thyroidectomy, the presence of LVI should be considered as an indicator of aggressive clinicopathological features and those patients should be followed up carefully for recurrences and metastasis

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
