Benefit of a Contralateral Routing of Signal Device for Unilateral Cochlear Implant Users.

Objective: To investigate objective and subjective effects of an adjunctive contralateral routing of signal (CROS) device at the untreated ear in patients with a unilateral cochlear implant (CI). Design: Prospective study of 10 adult experienced unilateral CI users with bilateral severe-to-profound hearing loss. Speech in noise reception (SNR) and sound localization were measured with and without the additional CROS device. SNR was measured by applying speech signals at the untreated/CROS side while noise signals came from the front (S90N0). For S0N90, signal sources were switched. Sound localization was measured in a 12-loudspeaker full circle setup. To evaluate the subjective benefit, patients tried the device for 2 weeks at home, then filled out the abbreviated Speech, Spatial and Qualities of Hearing Scale as well as the Bern benefit in single-sided deafness questionnaires. Results: In the setting S90N0, all patients showed a highly significant SNR improvement when wearing the additional CROS device (mean 6.4 dB, p < 0.001). In the unfavorable setting S0N90, only a minor deterioration of speech understanding was noted (mean -0.66 dB, p = 0.54). Sound localization did not improve substantially with CROS. In the two questionnaires, 12 of 14 items showed an improvement in mean values, but none of them was statistically significant. Conclusion: Patients with unilateral CI benefit from a contralateral CROS device, particularly in a noisy environment, when speech comes from the CROS ear side. © 2014 S. Karger AG, Basel.

Die Rolle des Benefit-Finding für die Qualität der Anpassung an das Leben nach dem Spitzensport

Die Lebensereignisforschung postuliert, dass die Anpassung an eine durch ein kritisches Ereignis veränderte Situation durch Benefit-Finding gefördert wird, indem Menschen Gewinnbringendes für ihr Leben erkennen (Filipp & Aymanns, 2010). Während in der frühen Forschung zum oft als kritisches Lebensereignis beschriebenen Karriereende im Spitzensport Benefit-Finding mitbedacht wurde, wird es in der aktuellen Forschung nur punktuell berücksichtigt (z.B. Curtis & Ennis, 1988, Wippert, 2011). Basierend auf dem Konzept Kritisches Lebensereignis (Filipp, 1995) untersucht die vorliegende Studie die Rolle des Benefit-Finding für die kurz-, mittel- und langfristige Qualität der Anpassung an das Karriereende. Methods: 290 Schweizer Spitzenathleten (Frauenanteil: 32.8%) aus 64 Sportarten wurden etwa 7.46 Jahre nach ihrem Karriereende mittels Fragebogen zum Benefit-Finding, Erleben des Karriereendes, zur Dauer und subjektiven Qualität der Anpassung an das Karriereende sowie zum psychischen Wohlbefinden befragt. Die Datenauswertung erfolgte mittels Strukturgleichungsmodellierung. Results: Das Modell zur Vorhersage der langfristigen Anpassungsqualität (psychische Wohlbefinden) an das Karriereende mit einer Varianzaufklärung von R2 = .26 passt recht gut zu den Daten (χ2 = 114.764, p ≤ .001, df = 56, CFI = .93, SRMR = .06, RMSEA = .06; AGFI = .91). Wie postuliert, hat das Ausmass von Benefit-Finding einen – über die kurz- und mittelfristige Anpassungsqualität (positive Emotionen, Anpassungsdauer und subjektive Anpassungsqualität) – vermittelten Effekt auf das psychische Wohlbefinden im Leben nach dem Spitzensport. Discussion/Conclusion: Das Konzept Kritisches Lebensereignis kristallisierte sich als zielführender Ansatz für die Analyse von zusammenwirkenden Faktoren hinsichtlich Qualität der Anpassung an das Leben nach dem Spitzensport heraus. Die Befunde indizieren, dass sportpsychologische Interventionen mit Fokus auf Benefit-Finding, zusammen mit anderen Elementen der gängigen Career-Assistance-Programme, kurzfristig für eine gelingende Transition und langfristig ein günstiges psychisches Wohlbefinden sinnvoll sind.

“Therapeutic Advertising”: When Do Female Consumers Really Benefit?

This research examines whether female consumers benefit from brand strategies that attempt to decrease their self-discrepancies by setting more realistic ideals (i.e., therapeutic advertising, such as Body Shop, Aerie, and Always). The results of our preliminary study reveal that therapeutic advertising leads to stronger self-conscious emotions than idealistic advertising. More specifically, it leads to stronger emotions of both pride and shame. However, the latter only holds true for female consumers low in self-liking and high difficulties in abandoning unattainable goals. Female consumers who like themselves and are able to abandon unattainable goals do not feel more ashamed when being exposed to therapeutic advertising compared to idealized advertising. These findings have implications for marketing managers and policy makers.

Clinical benefit response in pancreatic cancer trials revisited.

OBJECTIVES Clinical benefit response (CBR), based on changes in pain, Karnofsky performance status, and weight, is an established palliative endpoint in trials for advanced gastrointestinal cancer. We investigated whether CBR is associated with survival, and whether CBR reflects a wide-enough range of domains to adequately capture patients' perception. METHODS CBR was prospectively evaluated in an international phase III chemotherapy trial in patients with advanced pancreatic cancer (n = 311) in parallel with patient-reported outcomes (PROs). RESULTS The median time to treatment failure was 3.4 months (range: 0-6). The majority of the CBRs (n = 39) were noted in patients who received chemotherapy for at least 5 months. Patients with CBR (n = 62) had longer survival than non-responders (n = 182) (hazard ratio = 0.69; 95% confidence interval: 0.51-0.94; p = 0.013). CBR was predicted with a sensitivity and specificity of 77-80% by various combinations of 3 mainly physical PROs. A comparison between the duration of CBR (n = 62, median = 8 months, range = 4-31) and clinically meaningful improvements in the PROs (n = 100-116; medians = 9-11 months, range = 4-24) showed similar intervals. CONCLUSION CBR is associated with survival and mainly reflects physical domains. Within phase III chemotherapy trials for advanced gastrointestinal cancer, CBR can be replaced by a PRO evaluation, without losing substantial information but gaining complementary information.

A missing link between facilitation and plant species coexistence: nurses benefit generally rare species more than common ones

1. Positive interactions among plants can increase species richness by relaxing environmental filters and providing more heterogeneous environments. However, it is not known if facilitation could affect coexistence through other mechanisms. Most studies on plant coexistence focus on negative frequency-dependent mechanisms (decreasing the abundance of common species); here, we test if facilitation can enhance coexistence by giving species an advantage when rare. 2. To test our hypothesis, we used a global data set from drylands and alpine environments and measured the intensity of facilitation (based on co-occurrences with nurse plants) for 48 species present in at least 4 different sites and with a range of abundances in the field. We compared these results with the degree of facilitation experienced by species which are globally rare or common (according to the IUCN Red List), and with a larger data base including over 1200 co-occurrences of target species with their nurses. 3. Facilitation was stronger for rare species (i.e. those having lower local abundances or considered endangered by the IUCN) than for common species, and strongly decreased with the abundance of the facilitated species. These results hold after accounting for the distance of each species from its ecological optimum (i.e. the degree of functional stress it experiences). 4. Synthesis. Our results highlight that nurse plants not only increase the number of species able to colonize a given site, but may also promote species coexistence by preventing the local extinction of rare species. Our findings illustrate the role that nurse plants play in conserving endangered species and link the relationship between facilitation and diversity with coexistence theory. As such, they provide further mechanistic understanding on how facilitation maintains plant diversity.

The effects of benefit finding on athletes’ quality of adjustment to career termination

Retirement from elite sports requires athletes to cope with adjustments on an occupational, financial, physical, social or emotional level. Research on critical life events (e.g., Filipp & Aymanns, 2010) suggests that benefit finding, defined as “the process of deriving positive growth from adversity” (Cassidy et al., 2014), may have a positive impact on this transition. The present study examined the effects of benefit finding on the quality of adjustment to career termination in the short, middle and long term. Former Swiss elite athletes (N = 290) completed a written survey collecting information on a) their emotional reaction to career termination, b) the amount of adjustment in various respects, c) situational characteristics of their career termination, d) the duration and quality of the transition, and e) their subjective well-being. Using Latent Variable Modelling, finding benefit in career termination was found to have both a direct and an indirect effect on long-term well-being (γ=.18). It predicts favorable emotional reactions to career termination (γ = .53) and less adjustment (γ = -.38) which in turn shortens the transition duration (β = -.15 and β = .55, respectively) and quality (β = -.15), and finally augments well-being (β = .41). The data suggest that a focus on benefit finding in both crisis-prevention and crisis-coping interventions may prove useful to prevent crisis transitions.

Younger Stroke Patients With Large Pretreatment Diffusion-Weighted Imaging Lesions May Benefit From Endovascular Treatment.

BACKGROUND AND PURPOSE Lesion volume on diffusion-weighted magnetic resonance imaging (DWI) before acute stroke therapy is a predictor of outcome. Therefore, patients with large volumes are often excluded from therapy. The aim of this study was to analyze the impact of endovascular treatment in patients with large DWI lesion volumes (>70 mL). METHODS Three hundred seventy-two patients with middle cerebral or internal carotid artery occlusions examined with magnetic resonance imaging before treatment since 2004 were included. Baseline data and 3 months outcome were recorded prospectively. DWI lesion volumes were measured semiautomatically. RESULTS One hundred five patients had lesions >70 mL. Overall, the volume of DWI lesions was an independent predictor of unfavorable outcome, survival, and symptomatic intracerebral hemorrhage (P<0.001 each). In patients with DWI lesions >70 mL, 11 of 31 (35.5%) reached favorable outcome (modified Rankin scale score, 0-2) after thrombolysis in cerebral infarction 2b-3 reperfusion in contrast to 3 of 35 (8.6%) after thrombolysis in cerebral infarction 0-2a reperfusion (P=0.014). Reperfusion success, patient age, and DWI lesion volume were independent predictors of outcome in patients with DWI lesions >70 mL. Thirteen of 66 (19.7%) patients with lesions >70 mL had symptomatic intracerebral hemorrhage with a trend for reduced risk with avoidance of thrombolytic agents. CONCLUSIONS There was a growing risk for poor outcome and symptomatic intracerebral hemorrhage with increasing pretreatment DWI lesion volumes. Nevertheless, favorable outcome was achieved in every third patient with DWI lesions >70 mL after successful endovascular reperfusion, whereas after poor or failed reperfusion, outcome was favorable in only every 12th patient. Therefore, endovascular treatment might be considered in patients with large DWI lesions, especially in younger patients.

Estimating the benefit of a second bone anchored hearing implant in unilaterally implanted users with a testband.

Conclusion Using a second bone anchored hearing implant (BAHI) mounted on a testband in unilaterally implanted BAHI users to test its potential advantage pre-operatively under-estimates the advantage of two BAHIs placed on two implants. Objectives To investigate how well speech understanding with a second BAHI mounted on a testband approaches the benefit of bilaterally implanted BAHIs. Method Prospective study with 16 BAHI users. Eight were implanted unilaterally (group A) and eight were implanted bilaterally (group B). Aided speech understanding was measured. Speech was presented from the front and noise came either from the left, right, or from the front in two conditions for group A (with one BAHI, and with two BAHIs, where the second device was mounted on a testband) and in three conditions for group B (same two conditions as group A, and in addition with both BAHIs mounted on implants). Results Speech understanding in noise improved with the additional device for noise from the side of the first BAHI (+0.7 to +2.1 dB) and decreased for noise from the other side (-1.8 dB to -3.9 dB). Improvements were highest (+2.1 dB, p = 0.016) and disadvantages were smallest (-1.8 dB, p = 0.047) with both BAHIs mounted on implants. Testbands yielded smaller advantages and higher disadvantages of the additional BAHI (average difference = -0.9 dB).
