METHODSA systematic search of the Ovid MEDLINE and EMBASE databases by independent reviewers identified 70 articles including a total of 932141 IBD patients or IBD-related hospitalizations. RESULTSIn those with IBD, CDI is associated with increased morbidity, including subsequent escalation in IBD medical therapy, urgent colectomy and increased hospitalization, as well as excess mortality. Vancomycin-containing regimens are effective first-line therapies for CDI in IBD inpatients. No prospective data exists with regards to the safety or efficacy of initiating or maintaining corticosteroid, immunomodulator, or biologic therapy to treat IBD in the setting of CDI. Corticosteroid use is a risk factor for the development of CDI, while immunomodulators and biologics are not. CONCLUSIONStrong recommendations regarding when to initiate IBD specific therapy in those with CDI are precluded by a lack of evidence. However, based on expert opinion and observational data, initiation or resumption of immunosuppressive therapy after 48-72 h of targeted antibiotic treatment for CDI may be considered.展开更多

Previous studies have been mainly focused on how each of the two has influenced students' performances and achievement. However, according to the theoretical framework proposed by Brookhart (1997), it has been suggested that teachers' feedback may influence student motivation first, which, in turn, may have an impact on students' performances and achievement. Therefore, this paper first examines the nature and different types of feedback, and then gives a summary and critique of research studies on the relationship between teachers' feedback and student motivation. Areas that deserve further study are also indicated.展开更多

Then, combined with the detailed geology of Sichuan Basin, the effective gas-generating intensity of the Lower Cambrian source rock is approximately estimated by applying these parameters.展开更多
