Sepsis with an Atopobium-Like Species in a Patient with Fournier's Gangrene

Atopobium species are Gram-positive, anaerobic, catalase-negative, fastidious bacteria belonging to the family Coriobacteriaceae. We report the isolation of an Atopobium-like species in a patient with Fournier''s gangrene and highlight the role of 16S rRNA gene sequencing in the identification of fastidious organisms in the clinical laboratory.     

The relevance of team characteristics and team directed strategies in the implementation of nursing innovations: A literature review

BackgroundImplementation of innovations is a complex and intensive procedure in which different strategies can be successful. In nursing, strategies often focus on intrinsic motivation, competencies and attitudes of individual nurses while ignoring the social context. Since nurses often work in teams, identifying relevant team characteristics and successful team directed strategies may contribute to the implementation of innovations. The literature was searched for evidence.MethodsA literature review was performed including key words related to nursing teams, innovations, team characteristics and team-directed strategies. On-line databases were searched (MEDLINE, CINAHL, PsycINFO, ERIC database and Cochrane reviews CENTRAL). The journal Quality and Safety in Healthcare (QSHC) was hand searched. Methodological quality was assessed.ResultsInitially, 323 titles were found. Screening of titles and abstracts and full texts resulted in nine articles meeting the inclusion criteria. The methodological quality of the studies was generally low. The innovations included different types of practices. Fifteen different team characteristics were labeled according to six features of successful teams.Twenty-one different team-directed strategies were identified and inductively categorized.ConclusionFew studies and little evidence were found for the relevance of team characteristics and team directed strategies in the implementation of nursing innovations. Feedback was most frequently used as a strategy. Leadership could be labeled as a team characteristic as well as a team directed strategy. Further research should be of good methodological quality and focusing on patient outcomes and time and costs invested in strategy delivery. This increases scientific knowledge on nursing implementation strategies focusing on leadership.     

Antibiotics for coughing in general practice: a questionnaire study to quantify and condense the reasons for prescribing

Background  

Antibiotics are being overprescribed in ambulant care, especially for respiratory tract infections (RTIs). Gaining insight into the actual reasons for prescribing remains important for the design of effective strategies to optimise antibiotic prescribing. We aimed to determine items of importance for the antibiotic prescribing decision and to make them operational for an intervention trial.     

CPT performance in major depressive disorder before and after treatment with imipramine or fluvoxamine

Numerous neuropsychological studies have reported deficits in cognitive and attentional functioning in depressed patients. However, there are limited data available about unmedicated depressed patients and the effects of antidepressant treatment on attentional performance. In this study, a Continuous Performance Test (CPT) was employed to evaluate the attentional performance of depressed inpatients during a drugfree period (n=52) in comparison to healthy control subjects (n=73). After 4 weeks of double-blind treatment with imipramine (TCA) or fluvoxamine (SSRI) at adequate plasma levels the CPT performance was studied again. We found that the unmedicated patients had a significantly impaired performance on all CPT parameters (reaction time, omission errors and commission errors) in comparison to the controls. None of the CPT parameters correlated with the severity of the depression or the level of psychomotor retardation. However, the CPT performance in the patient group was significantly related to subjective mood state (depression, tension). Double-blind treatment with imipramine or fluvoxamine resulted in an improvement of the CPT performance. In the imipramine treatment group the mean reaction time decreased significantly, and after treatment with fluvoxamine a significant decrease of the mean reaction time and the number of omission errors was detected. Both antidepressants induced a significant improvement of clinical state, but we did not find a relationship between the altered CPT performance and the changes on the clinical scales. Future studies should investigate other mechanisms underlying the improved attentional performance after treatment.
