    BACKGROUND: It is unknown whether decompressive craniectomy improves clinical outcome for people with spontaneous severe deep intracerebral haemorrhage. The SWITCH trial aimed to assess whether decompressive craniectomy plus best medical treatment in these patients improves outcome at 6 months compared to best medical treatment alone.METHODS: In this multicentre, randomised, open-label, assessor-blinded trial conducted in 42 stroke centres in Austria, Belgium, Finland, France, Germany, the Netherlands, Spain, Sweden, and Switzerland, adults (18-75 years) with a severe intracerebral haemorrhage involving the basal ganglia or thalamus were randomly assigned to receive either decompressive craniectomy plus best medical treatment or best medical treatment alone. The primary outcome was a score of 5-6 on the modified Rankin Scale (mRS) at 180 days, analysed in the intention-to-treat population. This trial is registered with ClincalTrials.gov, NCT02258919, and is completed.FINDINGS: SWITCH had to be stopped early due to lack of funding. Between Oct 6, 2014, and April 4, 2023, 201 individuals were randomly assigned and 197 gave delayed informed consent (96 decompressive craniectomy plus best medical treatment, 101 best medical treatment). 63 (32%) were women and 134 (68%) men, the median age was 61 years (IQR 51-68), and the median haematoma volume 57 mL (IQR 44-74). 42 (44%) of 95 participants assigned to decompressive craniectomy plus best medical treatment and 55 (58%) assigned to best medical treatment alone had an mRS of 5-6 at 180 days (adjusted risk ratio [aRR] 0·77, 95% CI 0·59 to 1·01, adjusted risk difference [aRD] -13%, 95% CI -26 to 0, p=0·057). In the per-protocol analysis, 36 (47%) of 77 participants in the decompressive craniectomy plus best medical treatment group and 44 (60%) of 73 in the best medical treatment alone group had an mRS of 5-6 (aRR 0·76, 95% CI 0·58 to 1·00, aRD -15%, 95% CI -28 to 0). Severe adverse events occurred in 42 (41%) of 103 participants receiving decompressive craniectomy plus best medical treatment and 41 (44%) of 94 receiving best medical treatment.INTERPRETATION: SWITCH provides weak evidence that decompressive craniectomy plus best medical treatment might be superior to best medical treatment alone in people with severe deep intracerebral haemorrhage. The results do not apply to intracerebral haemorrhage in other locations, and survival is associated with severe disability in both groups.FUNDING: Swiss National Science Foundation, Swiss Heart Foundation, Inselspital Stiftung, and Boehringer Ingelheim.</p

    In Familienunternehmen beeinflussen familiäre Interessen unternehmerischen Verhaltensweisen und Unternehmensziele. Die voliegende Dissertation erforscht diese Zusammenhänge in qualitativen wie quantitativen Studien. Die Ergebnisse zeigen, dass für Familienunternehmen insbesondere soziales und regional kooperierendes Verhalten, sowie nicht-finanzielle Unternehmensziele von Bedeutung sind.Family-related interests alter entrepreneurial attitudes and performance goals in family firms. The dissertation at hand explores and explains these connections through qualitative and quantitative studies. Findings show that in the family firm context social and regional embeddedness, as well as non-financial performance goals are playing particularly important roles.von Andreas KallmünzerAbweichender Titel laut Übersetzung der Verfasserin/des VerfassersInnsbruck, Univ., Diss., 2015OeBB(VLID)45075

    ENTREPRENEURIAL ORIENTATION AND DIGITALIZATION IN THE FINANCIAL SERVICE INDUSTRY: A CONTINGENCY APPROACH

    No full text
    Financial service firms, and banks in particular, are faced with a shift from traditional, interpersonal forms of service to online services. Digital technologies are more and more becoming today’s standard and challenge traditional business models in the banking sector. Building on the concept of Entrepreneurial Orientation (EO), this study of banks in Germany, Switzerland and Liechtenstein aims at developing insights that explain how banks can use the tactics and strategies associated with EO to achieve superior performance in the digitalization age. Results from a survey in 102 banks show that: 1) banks that display high levels of EO report a higher level of performance, and 2) the relationship between strategic vision on digitalization and performance is moderated by EO. These results indicate that the sheer level of digitalization of a bank does not affect profitability. Instead, banks should develop a clear vision on digitalization that is characterized by innovation, being ahead of the competition, and a willingness to take risks

    Technology is rapidly changing the financial industry. Banks, in particular, are faced with a shift from traditional, interpersonal forms of service to digital financial services. These digital technologies are more and more becoming today's standard in the banking sector, they challenge traditional business models, and they provide opportunities for banks to capitalize on. Building on the concept of entrepreneurial orientation (EO), this study of banks in Germany, Switzerland, and Liechtenstein aims at developing insights that explain how banks can use the tactics and strategies associated with EO to achieve superior performance in the digitalization age. The results from a survey in 102 banks show that: 1) banks that display high levels of EO report a higher level of performance, and 2) the relationship between a banks’ strategic vision on digitalization, and performance is moderated by EO. These results indicate that the sheer level of the digitalization of a bank does not affect profitability. Instead, in this time of technological change banks should develop a clear vision on digitalization that is characterized by innovation, being ahead of the competition, and a willingness to take risks

    Quantitative Signal Intensity in Fluid-Attenuated Inversion Recovery and Treatment Effect in the WAKE-UP Trial

    International audienceBackground and Purpose— Relative signal intensity of acute ischemic stroke lesions in fluid-attenuated inversion recovery (fluid-attenuated inversion recovery relative signal intensity [FLAIR-rSI]) magnetic resonance imaging is associated with time elapsed since stroke onset with higher intensities signifying longer time intervals. In the randomized controlled WAKE-UP trial (Efficacy and Safety of MRI-Based Thrombolysis in Wake-Up Stroke Trial), intravenous alteplase was effective in patients with unknown onset stroke selected by visual assessment of diffusion weighted imaging fluid-attenuated inversion recovery mismatch, that is, in those with no marked fluid-attenuated inversion recovery hyperintensity in the region of the acute diffusion weighted imaging lesion. In this post hoc analysis, we investigated whether quantitatively measured FLAIR-rSI modifies treatment effect of intravenous alteplase. Methods— FLAIR-rSI of stroke lesions was measured relative to signal intensity in a mirrored region in the contralesional hemisphere. The relationship between FLAIR-rSI and treatment effect on functional outcome assessed by the modified Rankin Scale (mRS) after 90 days was analyzed by binary logistic regression using different end points, that is, favorable outcome defined as mRS score of 0 to 1, independent outcome defined as mRS score of 0 to 2, ordinal analysis of mRS scores (shift analysis). All models were adjusted for National Institutes of Health Stroke Scale at symptom onset and stroke lesion volume. Results— FLAIR-rSI was successfully quantified in stroke lesions in 433 patients (86% of 503 patients included in WAKE-UP). Mean FLAIR-rSI was 1.06 (SD, 0.09). Interaction of FLAIR-rSI and treatment effect was not significant for mRS score of 0 to 1 ( P =0.169) and shift analysis ( P =0.086) but reached significance for mRS score of 0 to 2 ( P =0.004). We observed a smooth continuing trend of decreasing treatment effects in relation to clinical end points with increasing FLAIR-rSI. Conclusions— In patients in whom no marked parenchymal fluid-attenuated inversion recovery hyperintensity was detected by visual judgement in the WAKE-UP trial, higher FLAIR-rSI of diffusion weighted imaging lesions was associated with decreased treatment effects of intravenous thrombolysis. This parallels the known association of treatment effect and elapsing time of stroke onset
