Экономическая безопасность функционирования предприятия в условиях сетевой экономики

В наше время возникновение сетевых особенностей в экономике связывают с развитием информационных технологий, что приводит к эволюции современных экономических систем, развитию нерыночных механизмов регулирования и сетевых организационных структур. Другими словами, сетевые экономические отношения играют особую роль в процессе координации экономических взаимодействий. Данные изменения обостряют проблему экономической безопасности предприятия в условиях развития межорганизационных взаимодействий формального и неформального характера с позиции сетевой экономики

Expanding the Grading of Recommendations Assessment, Development, and Evaluation (Ex-GRADE) for Evidence-Based Clinical Recommendations: Validation Study

Clinicians use general practice guidelines as a source of support for their intervention, but how much confidence should they place on these recommendations? How much confidence should patients place on these recommendations? Various instruments are available to assess the quality of evidence of research, such as the revised Wong scale (R-Wong) which examines the quality of research design, methodology and data analysis, and the revision of the assessment of multiple systematic reviews (R-AMSTAR), which examines the quality of systematic reviews

Comparison of two different composite resins used for tooth reshaping and diastema closure in a 4-year follow-up

Aims: This aim of this study is to evaluate and to compare the clinical performances of two nanohybrid composite resin systems used for diastema closure and tooth reshaping at 4 years.Subjects and Methods: Twenty‑three patients with midline or multidiastema problem were enrolled in this study. Nanohybrid resin composite systems to be used on each patient were randomly selected. Thirty seven teeth of 10 patients were restored with Filtek‑Z550 (3M/ESPE) in combination with Adper™ Single Bond 2 (3M/ESPE) etch and rinse adhesive in Group 1 whereas 39 teeth of 13 patients were restored with Charisma‑Diamond (Heraeus Kulzer) in combination with Gluma2 Bond (Heraeus Kulzer) etch and rinse adhesive in Group 2, by two operators. Esthetic, functional, and biological properties of the restorations were evaluated at baseline, 1, 2, 3, and 4 years using foreign direct investment criteria by two independent examiners. Statistical Analysis Used: The data were evaluated using Fisher’s Chi‑Square (P = 0.05).Results: Fifty‑eight restorations (19 patients) with a mean service time of 43.4 months were evaluated (recall rate 82.6%). One Filtek‑Z550 and two Charisma‑Diamond restorations were repaired due to partial fracture (Score 4). Survival rates of Group 1 and Group 2 were 96.3% and 93.5%, respectively (Kaplan–Meier) (P > 0.05). Qualitative deteriorations were observed within each group according to baseline regarding surface luster, surface/marginal staining, marginal adaptation, patient’s view, and periodontal response (P < 0.05). However, there were no significant differences between two restorative materials for any of the criteria assessed (P > 0.05).Conclusions: Both nanohybrid composite resin systems revealed esthetically, functionally, and biologically acceptable clinical performance when used for diastema closure and tooth reshaping at 4 years.Keywords: Clinical performance, composite resin buildup, diastema closur

Abortion associated with Campylobacter upsaliensis.

Campylobacter upsaliensis was isolated from the blood and fetoplacental material of an 18-week-pregnant woman who had contact with a household cat. We believe this is the first report of abortion associated with C. upsaliensis infection
