Assessment of patients with symptoms suggestive of acute coronary syndrome : the use of high sensitive cardiac troponin T and a risk score

The aim of this thesis was to evaluate patients with symptoms suggestive of acute coronary syndrome with regard to early diagnosis and prognosis by the use of high sensitive cardiac troponin T and a risk score: a low-risk group in which admission and further investigations may not be necessary. In paper I, the early diagnostic value of high sensitive cardiac troponin T (hs-cTnT) was compared with conventional cardiac troponin assays in 233 patients with symptoms suggestive of acute coronary syndrome (ACS). When acute myocardial infarction (MI) was defined according to conventional cardiac troponins and the lowest level with a coefficient of variation (CV) ≤ 10% for each method was used as decision limit, hs-cTnT had a higher sensitivity than the conventional cardiac troponins. When acute MI was defined according to hs-cTnT, hs-cTnT performed better than the conventional cardiac troponins at different decision limits and had the largest Area Under Curve (AUC) in ROC analysis. In paper II, the prognostic value of hs-cTnT was compared with conventional cardiac troponin assays in 231 patients with symptoms suggestive of ACS. When the lowest level with a CV ≤ 10% for each method was used as decision limit,hs-cTnT identified more high-risk patients. After adjusting for differences in clinical baseline characteristics, hs-cTnT and N-terminal pro B-type natriuretic peptide (NT-proBNP) were independently associated with outcome. By combining hs-cTnT and NT-proBNP, patients could be divided into low-, intermediate- and high-risk groups. In paper III, HEART score was validated in 410 consecutive patients with chest pain. Of 247 (60.2 %) patients in HEART score 0-3, one patient (0.4%) had a combined endpoint. Of 144 (35.1 %) patients in heart score 4-6, 19 (13.2 %) patients had a combined endpoint. Of 19 (4.6%) patients in HEART score 7-10, 10 (52.6 %) patients had a combined endpoint. Of all admitted patients, 34.3 % had a HEART score 0-3. In paper IV: 48,594 patients admitted because of symptoms suggestive of ACS were included to examine the effects of introducing hs-cTnT into clinical practice. 25% had hs-cTnT < 14 ng/L (group 1), 22 % had hs-cTnT 14-49 ng/L group 2) and 53 % had hs-cTnT ≥ 50 ng/L (group 3). From group 1 to 3, there was a stepwise increase with regard to proportion of patients with significant coronary stenoses, left ventricular systolic dysfunction and death during follow-up. Thus, the introduction of hs-cTnT has led to a large proportion of patients with minor cardiac troponin elevation (14-49 ng/L). The majority with minor elevation do not have myocardial infarction but are still at high risk. When dividing patients into 20 groups according to hs-cTnT level, the adjusted mortality started to increase at hs-cTnT level of 14 ng/L. Conclusion: hs-cTnT improves early diagnosis and risk stratification compared with conventional cardiac troponin assays. An excellent risk prediction can be achieved by combining hs-cTnT and NT-proBNP in an easily used algorithm. The introduction of hs-cTnT has resulted in identification of a large population with only minor elevation of hs-cTnT (14-49 ng/L) but are still at high risk. HEART score may be a useful tool for evaluation of chest pain patients and identify a low-risk group in which admission and further investigations may not be necessary

A Pedagogical Strategy to Teach Entrepreneurship: An Observation Based on Literature

Among the common contemporary interests of universities is the development of students’ entrepreneurship due to the vital implication entrepreneurship has on personal success, social contribution, employability and competitiveness. This interest is taking different forms including adding courses or degrees, setting clubs and organizing activities that promote the entrepreneurial culture in the university ecosystem. There exists a plethora of studies on the educational aspects and teaching settings needed to attain goals and achieve outcomes. This literature shows a lack of experience in formal education in teaching and learning for real life. This leads faculty and students to perceive entrepreneurial education as another means for passing exams and getting certificates, without giving due importance to the link between this study and the needs of real life. This article aims to highlight a pedagogical strategy using an interdisciplinary approach to teach entrepreneurship. The main components of this strategy are the development of faculty and students, the interdisciplinary nature of teaching and the proper partnership with the industry. Accordingly, the pertinence to involve faculty members in the process is deliberated, the appropriateness of maintaining interdisciplinarity is highlighted and the academia industry relationship is revisited with observations on its apt directions. In closing, the outcome of the defined strategy on the components of the educational process is considered through a brief comparison between outcomes-based and competencybased methodologies, which highlights the appropriateness of the latter for the entrepreneurship education. &nbsp; &nbsp; Keywords: pedagogical strategy, entrepreneurship education, interdisciplinarity, academia industry relationship, CB

Knowledge Gap Hypothesis and Pandemics: Covid-19 Knowledge, Communication Inequality, and Media Literacy in Lebanon

The study examines the knowledge gap hypothesis during the Covid-19 pandemic in a country experiencing severe social, political, and economic turmoil and inequality. The research design assesses Covid-19 knowledge through 13 variables and incorporates income, education, gender, and media literacy among the socioeconomic status variables. It also includes television exposure, social media exposure, and social media posting as media use measures. A cross-sectional survey of adults living in Lebanon was implemented between March 27 and April 23, 2020. The study aimed for a nationally representative probability sample of 1,536 participants (95% CI, ±2.5%) and received 792 valid responses (51.6% response rate). The results show a positive relationship between Covid-19 knowledge and education, media literacy, and social media exposure, but no relationship between Covid-19 knowledge and income, gender, television exposure, and social media posting behavior. The evidence shows a widening of the knowledge gap for those more likely to post on social media and a narrowing of the knowledge gap for those more exposed to social media news, but the observed narrowing of the knowledge gap for television exposure was not statistically generalizable. Finally, the evidence shows that media literacy maintains the knowledge gap by almost identically increasing the knowledge level for both low and high socioeconomic groups, although the limitations in measuring media literacy merit further exploration

Urban Development in Beirut: Gender and Space

While tackling the gender/urban development approach is new, but widely spread in the western world, the subject is almost irrelevant to Middle-Eastern research. The case study of one neighborhood in the cosmopolitan and distinctive Beirut explores this approach while focusing on women, either as recipients or as producers within their experience of space and their involvement with urban material. &nbsp

Distribution of Ammonium-Oxidizing Bacteria in Sediment with Relation to Water Quality at the Musi River, Indonesia

The Musi River is located in the southern Sumatra, Indonesia. Most of activities, i.e. agricultural, industrial, and urban activities are considered as being major sources of chemicals and nutrients with their waste products effluent into the river. Nitrification, the microbial oxidation of ammonia to nitrite and nitrate, occurs in a wide variety of environments and naturally remove anthropogenic N pollution. The purpose of this research was to determine of distribution of ammonium-oxidizing bacteria (AOB) in sediment with relation to water quality at the Musi river area. This study was conducted on rainy and dry season 2016 at five sampling sites from the freshwater to seawater at high and low tide conditions, the sampling sites are station St1 (Gandus), station St2 (Palembang city), station St3 (Upang), station St4 (Sungsang), and station St5 (Sea). Sediment samples were collected from the surface layer by using an Ekman grab. Some water quality such as salinity, temperature, pH, and dissolved oxygen (DO) were directly analyzed in the field, while other water quality such as NH4-N, NO2-N, and NO3-N were analyzed in the laboratory. The Density of AOB was determined by the most probable number of (MPN) method. The PCA was used to correlate variations of the AOB with physicochemical properties using software Xlstat. The results showed that the physicochemical properties had a range of salinity of 0 to 20 ppt, temperature of 29.21 to 31.82oC, pH of 4.88 to 7.93, DO of 3.44 to 11.33 mg/l, NH4-N in sediment of 0.04 to 0.87 mg/l, NO2-N in sediment of 0.01 to 1.77 mg/l, NO3-N in sediment of 0.09 to 2.08 mg/l. The density of AOB ranged from 7.2 x 102 to 6.1 x 103 cells/g sediment. Principal component analyses showed that temperature, pH, DO, and concentrations of nutrient contributed to density of AOB
