Thrombolyse bei tiefer Venenthrombose? [Thrombolytic therapy in deep venous thrombosis?]

Sie sehen eine 45-jährige Patientin mit einem bläulich-zyanotischen rechten Bein. Vor fünf Tagen habe ein Spannungsschmerz in der Wade begonnen und sich zunehmend in den Oberschenkel hochgezogen. Die rechte Wade misst im Umfang 4 cm mehr als die linke. Die Anamnese ergibt keine familiäre oder persönliche Vorgeschichte einer thromboembolischen Erkrankung. Die Patientin ist übergewichtig ( BMI 35 kg/m2) und nimmt seit einigen Jahren eine Östrogen-Progesteron-Kombination. Der Ultraschall zeigt eine Thrombose der tiefen Beinvenen, die bis in die äussere Beckenvene reicht.

Editorial research and the publication process in biomedicine and health: Report from the Esteve Foundation Discussion Group, December 2012.

Despite the fact that there are more than twenty thousand biomedical journals in the world, research into the work of editors and publication process in biomedical and health care journals is rare. In December 2012, the Esteve Foundation, a non-profit scientific institution that fosters progress in pharmacotherapy by means of scientific communication and discussion organized a discussion group of 7 editors and/or experts in peer review biomedical publishing. They presented findings of past editorial research, discussed the lack of competitive funding schemes and specialized journals for dissemination of editorial research, and reported on the great diversity of misconduct and conflict of interest policies, as well as adherence to reporting guidelines. Furthermore, they reported on the reluctance of editors to investigate allegations of misconduct or increase the level of data sharing in health research. In the end, they concluded that if editors are to remain gatekeepers of scientific knowledge they should reaffirm their focus on the integrity of the scientific record and completeness of the data they publish. Additionally, more research should be undertaken to understand why many journals are not adhering to editorial standards, and what obstacles editors face when engaging in editorial research.

Scientific value of systematic reviews: survey of editors of core clinical journals.

BACKGROUND: Synthesizing research evidence using systematic and rigorous methods has become a key feature of evidence-based medicine and knowledge translation. Systematic reviews (SRs) may or may not include a meta-analysis depending on the suitability of available data. They are often being criticised as 'secondary research' and denied the status of original research. Scientific journals play an important role in the publication process. How they appraise a given type of research influences the status of that research in the scientific community. We investigated the attitudes of editors of core clinical journals towards SRs and their value for publication.¦METHODS: We identified the 118 journals labelled as "core clinical journals" by the National Library of Medicine, USA in April 2009. The journals' editors were surveyed by email in 2009 and asked whether they considered SRs as original research projects; whether they published SRs; and for which section of the journal they would consider a SR manuscript.¦RESULTS: The editors of 65 journals (55%) responded. Most respondents considered SRs to be original research (71%) and almost all journals (93%) published SRs. Several editors regarded the use of Cochrane methodology or a meta-analysis as quality criteria; for some respondents these criteria were premises for the consideration of SRs as original research. Journals placed SRs in various sections such as "Review" or "Feature article". Characterization of non-responding journals showed that about two thirds do publish systematic reviews.¦DISCUSSION: Currently, the editors of most core clinical journals consider SRs original research. Our findings are limited by a non-responder rate of 45%. Individual comments suggest that this is a grey area and attitudes differ widely. A debate about the definition of 'original research' in the context of SRs is warranted.

Hydrokolloid bei diabetischen Fussulzera: besser als herkömmliche Wundverbände

Sie betreuen einen 82-jährigen Typ-2-Diabetiker mit einer 1 cm grossen Wunde an der Grosszehe. Der Patient hat sich geschnitten, als er Hornhaut entfernte. Die Wunde vergrössert sich seither stetig und sondert Flüssigkeit ab. Die Wundumgebung ist hyperkeratotisch, aufgeweicht, leicht fibrinös und feucht. Weder ist Kontakt zum darunterliegenden Knochen vorhanden noch gibt es Infektionszeichen. Der Patient ist für eine Neuropathie und Veneninsuffizienz bekannt; die Fusspulse sind spürbar. Seine Blutzuckerwerte sind stabil, der HbA1c-Wert liegt bei 7,5%. Er möchte die Wunde selbst weiter versorgen und sich regelmässig duschen können.

Pre-hospital tracheal intubation in patients with traumatic brain injury: systematic review of current evidence.

BACKGROUND: We reviewed the current evidence on the benefit and harm of pre-hospital tracheal intubation and mechanical ventilation after traumatic brain injury (TBI). METHODS: We conducted a systematic literature search up to December 2007 without language restriction to identify interventional and observational studies comparing pre-hospital intubation with other airway management (e.g. bag-valve-mask or oxygen administration) in patients with TBI. Information on study design, population, interventions, and outcomes was abstracted by two investigators and cross-checked by two others. Seventeen studies were included with data for 15,335 patients collected from 1985 to 2004. There were 12 retrospective analyses of trauma registries or hospital databases, three cohort studies, one case-control study, and one controlled trial. Using Brain Trauma Foundation classification of evidence, there were 14 class 3 studies, three class 2 studies, and no class 1 study. Six studies were of adults, five of children, and three of both; age groups were unclear in three studies. Maximum follow-up was up to 6 months or hospital discharge. RESULTS: In 13 studies, the unadjusted odds ratios (ORs) for an effect of pre-hospital intubation on in-hospital mortality ranged from 0.17 (favouring control interventions) to 2.43 (favouring pre-hospital intubation); adjusted ORs ranged from 0.24 to 1.42. Estimates for functional outcomes after TBI were equivocal. Three studies indicated higher risk of pneumonia associated with pre-hospital (when compared with in-hospital) intubation. CONCLUSIONS: Overall, the available evidence did not support any benefit from pre-hospital intubation and mechanical ventilation after TBI. Additional arguments need to be taken into account, including medical and procedural aspects.
