Gebisssanierung unter Intubationsnarkose (ITN) bei Kindern und Jugendlichen. Retrospektive Analysen im Medizinischen Zentrum für Zahn-, Mund- und Kieferheilkunde der Universität Marburg

Das Ziel der retrospektiven Untersuchung war es, das Ausmaß der bestehenden Gebisserkrankungen, den Umfang der erforderlichen Therapie und die Indikation für die Zahnsanierung in Allgemeinanästhesie bei unter Intubationsnarkose behandelten Kindern zu eruieren. Darüber hinaus sollten die Arbeitshypothesen überprüft werden, ob die patientenspezifischen Eigenschaften biologisches Alter, Geschlecht und der allgemeinmedizinische Gesundheitszustand den Mundgesundheitszustand beeinflussen bzw. mit diesem in einem systematischen Zusammenhang stehen. Zu diesem Zweck wurden die Behandlungsunterlagen von 180 gebisssanierten null-bis volljährigen Kindern ausgewertet, die im Zeitraum von 2006-2010 im Universitätsklinikum Marburg in Intubationsnarkose behandelt worden waren. Die Daten wurden anonymisiert erhoben und der Kruskall-Wallis-Test zur Hypothesenüberprüfung verwendet. Die Gebissbefunderhebung erfolgte gemäß dmf-t- und DMF-T-Index

Why students use social networks for education: Extension of UTAUT2

Social networks sites have a considerable impact on all our life aspects, especially the educational sector. This study aims at identifying the factors affecting students’ actual usage of social networks sites for educational purposes in Jordanian universities.  The proposed model consists factors of UTAUT2 theory (Effort expectancy, Performance expectancy, Social influence, Facilitating condition, Habit, Hedonic motivation). In addition to two added factors (lecturer support, and student-related factors) as an extension. The study was conducted in (6) Jordanian universities, where (381) questionnaires were returned from the study sample with a response rate of (95%) from the total questionnaires that were distributed online. The results showed that (Performance expectancy, Social influence, Effort expectancy, Habit, lecturer support, and student-related factors) have a positive impact on the actual usage of social networks sites for educational purposes in Jordanian universities, while the factors (Facilitating condition and Hedonic motivation) don’t support their hypotheses).</jats:p

Why students use social networks for education: extension of UTAUT2

Social networks sites have a considerable impact on all our life aspects, especially the educational sector. This study aims at identifying the factors affecting students’ actual usage of social networks sites for educational purposes in Jordanian universities. The proposed model consists of factors of the Unified Theory of Acceptance and Use of Technology UTAUT2 theory (Effort expectancy, Performance expectancy, Social influence, Facilitating condition, Habit, Hedonic motivation) which is extended by adding two external factors (lecturer support, and student-related factors) as an extension. The study was conducted in (6) Jordanian universities, where (411) questionnaires were returned from the study sample with (380) responses are acceptable for data analysis (a response rate of 93%) from the total questionnaires that were distributed online. The statistical package for social sciences (SPSS 23.0) was used to determine the factors affecting the students’ actual use of s for educational purposes. Results: The results showed that (Performance expectancy, Social influence, Effort expectancy, Habit, lecturer support, and student-related factors) have a positive impact on the actual usage of social networks sites for educational purposes in Jordanian universities, while the factors (Facilitating condition and Hedonic motivation) don’t support their hypotheses). Based on the results, the researcher introduced a number of recommendations for the decision makers in the higher education that could be positively reflected on increasing the adoption of SNS for educational process in public Jordanian UniversitiesPeer Reviewe

Corrigendum to “Association between Virulence Factors and Extended Spectrum Beta-Lactamase Producing Klebsiella pneumoniae

Klebsiella pneumoniae is considered an important opportunistic multidrug-resistant pathogen. Extended spectrum β-lactamases (ESBLs) and expression of a multitude of virulence factors may work in a harmony resulting in treatment failure. This study was undertaken to compare the virulence characteristics and genetic relatedness between ESBL and non-ESBL producing K. pneumoniae. Methods. Antibiotic sensitivity test of all isolates was determined by disc diffusion assay. Phenotypic and genotypic detection of ESBL were done. Various virulence factors and some virulence factor-associated genes were screened. Random amplified polymorphic DNA (RAPD) was employed to investigate the genetic fingerprints of ESBL from non-ESBL producing K. pneumoniae. Results. 50% of isolates were ESBL producers. A significant association was observed between ESBL production and biofilm (strong and moderate), serum resistance, and iss gene. Moreover, significant association between non-ESBL producers and hypermucoviscosity was identified. Dendogram analysis of RAPD profile classified K. pneumoniae isolates into four clusters (a, b, c, and d). Seventy-six percent of ESBL producers belonged to cluster a. In conclusion, this study suggests a correlation between ESBL production and some virulence factors. Therefore, success of treatment depends mainly on increased clinicians awareness and enhanced testing by laboratories to reduce the spread of these isolates
