Lösungsansätze für Nachbauprobleme durch bodenbürtige Pathogene im biologischen Erdbeeranbau
Soil-borne pathogens, above all Verticillium sp. cause plant losses and yield decreases in many Austrian strawberry fields, also in organic farming systems; in a research project possibilities to resolve this problem were examined. In a field trial, which was started 1998, organically managed and differently fertilized plots (green compost, manure, hornchips) were compared to an unfertilised control plot and to two mineral fertilized and conventionally treated plots; the differences in field characteristics of strawberries in 2004 and 2005 were low, but differences in storage and biochemical characteristics could be seen in 2005. Some new cultivars tested as alternative to the very sensitive 'Elsanta' planted in 2005 on several farms showed a higher tolerance to diseases and good yield and fruit quality characteristics. Brassica sp. planted as an intercrop before strawberries reduced the amount of microsclerotia of Verticillium dahliae in highly infested soils, nevertheless the system has to be optimised and adapted to our climatic and husbandry conditions in further trials
Possible solutions for replant problems caused by soil-borne pathogens in organic strawberry production
Soil-borne pathogens, above all Verticillium sp. cause plant losses and yield decreases in many Austrian
strawberry fields, also in organic farming systems; in a research project possibilities to resolve this problem
were examined. In a field trial, which was started 1998, organically managed and differently fertilized plots
(green compost, manure, hornchips) were compared to an unfertilised control plot and to two mineral
fertilized and conventionally treated plots; the differences in field characteristics of strawberries in 2004 and
2005 were low, but differences in storage and biochemical characteristics could be seen in 2005. Some new
cultivars tested as alternative to the very sensitive 'Elsanta' planted in 2005 on several farms showed a
higher tolerance to diseases and good yield and fruit quality characteristics. Brassica sp. planted as an
intercrop before strawberries reduced the amount of microsclerotia of Verticillium dahliae in highly infested
soils, nevertheless the system has to be optimised and adapted to our climatic and husbandry conditions in
further trials

Dakota Gold®-brand dried distiller’s grains with solubles: effects on finishing performance and carcass characteristics
A 153-day trial was conducted using
345 heifers to determine optimal level of
Dakota Gold dried distiller’s grains with
solubles (DDGS) in finishing diets based
on steam-flaked corn. Diets contained six
levels of DDGS: 0%, 15%, 30%, 45%,
60%, and 75%. DDGS affected average
daily gain, final weight and hot carcass
weight, all of which increased with 15%
DDGS and then decreased as additional
DDGS was added. Growth performance of
heifers fed 30% DDGS was similar to those
fed no DDGS. In general, heifers were
overfinished, with 61% being Yield Grade
3 or greater and 83% grading Choice or
Prime. Backfat tended to decrease with
addition of DDGS, and kidney, pelvic, and
heart fat and marbling scores tended to be
greatest for intermediate levels of DDGS.
Percentage of carcasses grading Choice or
Prime tended to be lower for heifers fed 60
or 75% DDGS
Variation in practice regarding pretreatment with dual antiplatelet therapy for patients with non–ST elevation myocardial infarction
BACKGROUND: Despite guideline recommendations, a significant number of patients with non–ST elevation myocardial infarction (NSTEMI) do not receive dual antiplatelet therapy (DAPT) before angiography “pretreatment.” While there may be valid clinical reasons to not pretreat, such as concern for bleeding or multivessel disease warranting coronary artery bypass graft surgery, the degree of variability and factors associated with DAPT pretreatment are unknown. METHODS AND RESULTS: From the multicenter TRIUMPH registry, 1632 NSTEMI patients were not taking DAPT on admission and were included in the study cohort. Among the study patients, only 22% patients received DAPT pretreatment. A multivariable logistic regression model showed that race other than white or black (odds ratio [OR] 0.41, 95% CI 0.21–0.83), hemoglobin level (OR 1.18, 95% CI 1.08–1.29), patients’ bleeding risk (assessed with NCDR CathPCI Bleeding Risk Score) (OR 0.85, 95% CI 0.74–0.99), and severe left ventricular dysfunction (OR 0.3, 95% CI 0.13–0.65) were the main predictors of pretreatment with DAPT, whereas likelihood of needing coronary artery bypass graft surgery (GRACE prediction model) was not (OR 1.09, 95% CI 0.88–1.35). Median ORs were calculated to assess variability of receiving DAPT pretreatment across sites after adjustment for patient characteristics. Receiving DAPT pretreatment varied substantially across sites (range 0–100%, mean OR 3.94, P<0.0001). CONCLUSIONS: While deviating from guideline‐recommended DAPT pretreatment in patients with NSTEMI was associated with patient factors (eg, bleeding risk), marked variation was present across sites after accounting for patient‐level characteristics. This suggests that site‐level interventions are needed to improve concordance with current guidelines
The influence of depth and velocity on age‐0 Scaphirhynchus sturgeon prey consumption: Implications for aquatic habitat restoration
After the pallid sturgeon (Scaphirhynchus albus) was listed as endangered in 1990, a variety of management actions focusing on early life history needs have been implemented to aid species recovery. Given the scarcity of age‐0 pallid sturgeon, managers and scientists have relied on sympatric congeners to evaluate the effectiveness of management actions in the short term; however, increased understanding of habitat requirements for age‐0 Scaphirhynchus sturgeon is still needed to appropriately focus management efforts. Recently, a lack of food‐producing and foraging habitats were proposed as potential limiting factors for pallid sturgeon, and the purpose of this study was to evaluate the current definition of these habitats at multiple spatial scales using data from age‐0 Scaphirhynchus sturgeon (shovelnose sturgeon [Scaphirhynchus platyrhynchus] or hybrid [shovelnose sturgeon x pallid sturgeon]). Results showed the water depths and velocities that currently define age‐0 pallid sturgeon foraging habitat had little effect on age‐0 Scaphirhynchus sturgeon prey consumption. Similar results occurred when evaluating the relationship between prey consumption and food‐producing habitat present 10, 20, and 30 days before capture. Assuming that individuals captured during this study were a valid surrogate, these results suggest that increasing foraging and food‐producing habitat as defined by the current depth and velocity criteria is unlikely to result in the desired benefits of increased growth and survival of age‐0 pallid sturgeon

Visuo-spatial cognition in Williams syndrome: Reviewing and accounting for the strengths and weaknesses in performance
Individuals with Williams syndrome typically show relatively poor visuo-spatial abilities in comparison to stronger verbal skills. However, individuals' level of performance is not consistent across all visuo-spatial tasks. The studies assessing visuo-spatial functioning in Williams syndrome are critically reviewed, in order to provide a clear pattern of the relative difficulty of these tasks. This prompts a possible explanation of the variability in performance seen which focuses on the processing demands of some of these tasks. Individuals with Williams syndrome show an atypical processing style on tests of construction, which does not affect tests of perception
Nuisance Bleeding With Prolonged Dual Antiplatelet Therapy After Acute Myocardial Infarction and its Impact on Health Status
ObjectivesThe purpose of this study was to examine the incidence of nuisance bleeding after AMI and its impact on QOL.BackgroundProlonged dual antiplatelet therapy (DAPT) is recommended after acute myocardial infarction (AMI) to reduce ischemic events, but it is associated with increased rates of major and minor bleeding. The incidence of even lesser degrees of post-discharge “nuisance” bleeding with DAPT and its impact on quality of life (QOL) are unknown.MethodsData from the 24-center TRIUMPH (Translational Research Investigating Underlying Disparities in Acute Myocardial Infarction Patients' Health Status) study of 3,560 patients, who were interviewed at 1, 6, and 12 months after AMI, were used to investigate the incidence of nuisance bleeding (defined as Bleeding Academic Research Consortium type 1). Baseline characteristics associated with “nuisance” bleeding and its association with QOL, as measured by the EuroQol 5 Dimension visual analog scale, and subsequent re-hospitalization were examined.ResultsNuisance (Bleeding Academic Research Consortium type 1) bleeding occurred in 1,335 patients (37.5%) over the 12 months after AMI. After adjusting for baseline bleeding and mortality risk, ongoing DAPT was the strongest predictor of nuisance bleeding (rate ratio [RR]: 1.44, 95% confidence interval [CI]: 1.17 to 1.76 at 1 month; RR: 1.89, 95% CI: 1.35 to 2.65 at 6 months; and RR: 1.39, 95% CI: 1.08 to 1.79 at 12 months; p < 0.01 for all comparisons). Nuisance bleeding at 1 month was independently associated with a decrement in QOL at 1 month (−2.81 points on EuroQol 5 Dimension visual analog scale; 95% CI: 1.09 to 5.64) and nonsignificantly toward higher re-hospitalization (hazard ratio: 1.20; 95% CI: 0.95 to 1.52).ConclusionsNuisance bleeding is common in the year after AMI, associated with ongoing use of DAPT, and independently associated with worse QOL. Improved selection of patients for prolonged DAPT may help minimize the incidence and adverse consequences of nuisance bleeding
