    Im Jahr 2018 startete die modellhafte Einführung der Ergänzenden unabhängigen Teilhabeberatung (EUTB®) nach § 32 Neuntes Buch Sozialgesetzbuch (SGB IX). Mit ihr wurden rund 500 Angebote in ganz Deutschland gefördert, in denen Menschen mit Behinderungen und ihre Angehörigen über Fragen der Rehabilitation und Teilhabe informiert und beraten werden. Die wissenschaftliche Begleitung der EUTB® adressiert grundsätzliche Fragen zu den Umsetzungs- und Wirkungsbedingungen der EUTB®. Ihre Ergebnisse zeigen, dass es der EUTB® auftragsgemäß gelungen ist, ein breit akzeptiertes Informations- und Beratungsangebot zu entwickeln, das die vorhandene Beratungsinfrastruktur im Bereich Rehabilitation und Teilhabe ergänzt. Im Zuge ihrer Etablierung konnte für die EUTB® - in der Regie der Fachstelle Teilhabeberatung - ein umfassendes System der Qualifizierung und Qualitätssicherung entwickelt werden, so dass zum Ende der Förderphase einheitliche Qualitätsstandards für die Beratung vorliegen und weiterentwickelt werden können. Die Zufriedenheit der Ratsuchenden mit der Beratung durch die EUTB® ist hoch. Die Klärung ihrer Anliegen und die Erreichung der wichtigsten Ziele gelingen nach ihrer Selbsteinschätzung häufig. Damit kann die EUTB® nachweislich zur Stärkung der Selbstbestimmung und gesellschaftlichen Teilhabe der Ratsuchenden beitragen. Die Beratung von Betroffenen für Betroffen als "Peer-Beratung" trägt zu einer wesentlichen Unterstützung des Angebots bei

    Background: The purpose of the study was to investigate a novel BRAF and CDK 4/6 inhibitor combination therapy in a murine model of BRAF-V600-mutant human melanoma monitored by F-18-FDG-PET/CT and diffusionweighted MRI (DW-MRI). Methods: Human BRAF-V600-mutant melanoma (A375) xenograft-bearing balb/c nude mice (n = 21) were imaged by 18F-FDG-PET/CT and DW-MRI before (day 0) and after (day 7) a 1-week BRAF and CDK 4/6 inhibitor combination therapy (n = 12;dabrafenib, 20 mg/kg/d;ribociclib, 100 mg/kg/d) or placebo (n = 9). Animals were scanned on a small animal PET after intravenous administration of 20 MBq F-18-FDG. Tumor glucose uptake was calculated as the tumor-to-liver-ratio (TTL). Unenhanced CT data sets were subsequently acquired for anatomic coregistration. Tumor diffusivity was assessed by DW-MRI using the apparent diffusion coefficient (ADC). Anti-tumor therapy effects were assessed by ex vivo immunohistochemistry for validation purposes (microvascular density -CD31;tumor cell proliferation -Ki-67). Results: Tumor glucose uptake was significantly suppressed under therapy (Delta TTLTherapy -1.00 +/- 0.53 vs.Delta TTLControl 0.85 +/- 1.21;p < 0.001). In addition, tumor diffusivity was significantly elevated following the BRAF and CDK 4/6 inhibitor combination therapy (Delta ADC(Therapy) 0.12 +/- 0.14 x 10(-3) mm(2)/s;Delta ADCControl -0.12 +/- 0.06 x 10(-3) mm(2)/s;p < 0.001). Immunohistochemistry revealed a significant suppression of microvascular density (CD31, 147 +/- 48 vs. 287 +/- 92;p = 0.001) and proliferation (Ki-67, 3718 +/- 998 vs. 5389 +/- 1332;p = 0.007) in the therapy compared to the control group. Conclusion: A novel BRAF and CDK 4/6 inhibitor combination therapy exhibited significant anti-angiogenic and anti-proliferative effects in experimental human melanomas, monitored by F-18-FDG-PET/CT and DW-MRI

    Effects of estrogen agonists on amphetamine-stimulated striatal dopamine release

    Based upon the observation that estrogen acts in the striatum to rapidly modulate dopamine (DA) neural transmission and DA-mediated behaviors, it has been postulated that these effects of estrogen are mediated by a specific, membrane-bound receptor mechanism. To further characterize the pharmacological specificity of the estrogen binding site, the present experiments examine effects of various estrogen agonists on amphetamine (AMPH)-induced DA release from striatal tissue of ovariectomized female rats, using a superfusion method. Catechol estrogens 4-, and 2-hydroxyestradiol, but not 2-methoxyestradiol, significantly enhance AMPH-induced striatal DA release. Estrogen metabolites, estrone and estriol, and the non-steroidal estrogen analog, diethylstilbestrol, are without effects. Estradiol conjugated to bovine serum albumin (BSA) mimics the effect of estradiol to enhance stimulated striatal DA release. These results indicate that the steroidal configuration and hydroxylation on the A-ring of estrogenic compounds may be important determinants of ligand binding to the putative estrogen binding site in the striatum. Furthermore, the effectiveness of the estradiol conjugated to BSA reinforces the idea of an external membrane-bound receptor binding site in the striatum.

    Background: Semaglutide, a GLP-1 receptor agonist, reduces the risk of major adverse cardiovascular events (MACE) in people with overweight or obesity, but the effects of this drug on outcomes in patients with atherosclerotic cardiovascular disease and heart failure are unknown. We report a prespecified analysis of the effect of once-weekly subcutaneous semaglutide 2·4 mg on ischaemic and heart failure cardiovascular outcomes. We aimed to investigate if semaglutide was beneficial in patients with atherosclerotic cardiovascular disease with a history of heart failure compared with placebo; if there was a difference in outcome in patients designated as having heart failure with preserved ejection fraction compared with heart failure with reduced ejection fraction; and if the efficacy and safety of semaglutide in patients with heart failure was related to baseline characteristics or subtype of heart failure. Methods: The SELECT trial was a randomised, double-blind, multicentre, placebo-controlled, event-driven phase 3 trial in 41 countries. Adults aged 45 years and older, with a BMI of 27 kg/m2 or greater and established cardiovascular disease were eligible for the study. Patients were randomly assigned (1:1) with a block size of four using an interactive web response system in a double-blind manner to escalating doses of once-weekly subcutaneous semaglutide over 16 weeks to a target dose of 2·4 mg, or placebo. In a prespecified analysis, we examined the effect of semaglutide compared with placebo in patients with and without a history of heart failure at enrolment, subclassified as heart failure with preserved ejection fraction, heart failure with reduced ejection fraction, or unclassified heart failure. Endpoints comprised MACE (a composite of non-fatal myocardial infarction, non-fatal stroke, and cardiovascular death); a composite heart failure outcome (cardiovascular death or hospitalisation or urgent hospital visit for heart failure); cardiovascular death; and all-cause death. The study is registered with ClinicalTrials.gov, NCT03574597. Findings: Between Oct 31, 2018, and March 31, 2021, 17 604 patients with a mean age of 61·6 years (SD 8·9) and a mean BMI of 33·4 kg/m2 (5·0) were randomly assigned to receive semaglutide (8803 [50·0%] patients) or placebo (8801 [50·0%] patients). 4286 (24·3%) of 17 604 patients had a history of investigator-defined heart failure at enrolment: 2273 (53·0%) of 4286 patients had heart failure with preserved ejection fraction, 1347 (31·4%) had heart failure with reduced ejection fraction, and 666 (15·5%) had unclassified heart failure. Baseline characteristics were similar between patients with and without heart failure. Patients with heart failure had a higher incidence of clinical events. Semaglutide improved all outcome measures in patients with heart failure at random assignment compared with those without heart failure (hazard ratio [HR] 0·72, 95% CI 0·60-0·87 for MACE; 0·79, 0·64-0·98 for the heart failure composite endpoint; 0·76, 0·59-0·97 for cardiovascular death; and 0·81, 0·66-1·00 for all-cause death; all pinteraction&gt;0·19). Treatment with semaglutide resulted in improved outcomes in both the heart failure with reduced ejection fraction (HR 0·65, 95% CI 0·49-0·87 for MACE; 0·79, 0·58-1·08 for the composite heart failure endpoint) and heart failure with preserved ejection fraction groups (0·69, 0·51-0·91 for MACE; 0·75, 0·52-1·07 for the composite heart failure endpoint), although patients with heart failure with reduced ejection fraction had higher absolute event rates than those with heart failure with preserved ejection fraction. For MACE and the heart failure composite, there were no significant differences in benefits across baseline age, sex, BMI, New York Heart Association status, and diuretic use. Serious adverse events were less frequent with semaglutide versus placebo, regardless of heart failure subtype. Interpretation: In patients with atherosclerotic cardiovascular diease and overweight or obesity, treatment with semaglutide 2·4 mg reduced MACE and composite heart failure endpoints compared with placebo in those with and without clinical heart failure, regardless of heart failure subtype. Our findings could facilitate prescribing and result in improved clinical outcomes for this patient group. Funding: Novo Nordisk

    Isoelectric focusing of proteolytic fragments from rabbit anti streptococcal antibodies of restricted heterogeneity

    No full text
    It is concluded that variations in the hinge region which link Fd and Fc portions of heavy chains and differences in Fc regions, contribute to the diversity of rabbit antibodies of restricted heterogeneity which may possess identical or very similar Fab regions. Whatever the origin of the heterogeneity of the constant region of H chain may be, isoelectric spectra of papain Fab fragments of restricted antibodies reflect better than the intact molecule the 'monoclonal' nature of the combining region of antibodies and should preferentially be used as a phenotypic marker of antibody producing cells.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

    (1) Background: To assess the treatment response of benign prostatic syndrome (BPS) following prostatic artery embolization (PAE) using a semi-automatic software analysis of magnetic resonance imaging (MRI) features and clinical indexes. (2) Methods: Prospective, monocenter study of MRI and clinical data of n = 27 patients with symptomatic BPS before and (1, 6, 12 months) after PAE. MRI analysis was performed using a dedicated semi-automatic software for segmentation of the central and the total gland (CG, TG), respectively; signal intensities (SIs) of T1-weighted (T1w), T2-weighted (T2w), and diffusion-weighted images (DWI), as well as intravesical prostatic protrusion (IPP) and prostatic volumes (CGV, TGV), were evaluated at each time point. The semi-automatic assessed TGV was compared to conventional TGV by an ellipse formula. International prostate symptom score (IPSS) and international consultation on incontinence questionnaire&ndash;urinary incontinence short form (ICIQ-UI SF) questionnaires were used as clinical indexes. Statistical testing in the form of ANOVA, pairwise comparisons using Bonferroni correction, and multiple linear correlations, were conducted using SPSS. (3) Results: TGV was significantly reduced one, six, and 12 months after PAE as assessed by the semi-automatic approach and conventional ellipse formula (p = 0.005; p = 0.025). CGV significantly decreased after one month (p = 0.038), but showed no significant differences six and 12 months after PAE (p = 0.191; p = 0.283). IPP at baseline was demonstrated by 25/27 patients (92.6%) with a significant decrease one, six, and 12 months after treatment (p = 0.028; p = 0.010; p = 0.008). Significant improvement in IPSS and ICIQ-UI SF (p = 0.002; p = 0.016) after one month correlated moderately with TGV reduction (p = 0.031; p = 0.05, correlation coefficients 0.52; 0.69). Apparent diffusion coefficient (ADC) values of CG significantly decreased one month after embolization (p &lt; 0.001), while there were no significant differences in T1w and T2w SIs before and after treatment at each time point. (4) Conclusions: The semi-automatic approach is appropriate for the assessment of volumetric and morphological changes in prostate MRI following PAE, able to identify significantly different ADC values post-treatment without the need for manual identification of infarct areas. Semi-automatic measured TGV reduction is significant and comparable to the TGV calculated by the conventional ellipse formula, confirming the clinical response after PAE
