Voters evaluate politicians not just by what they say, but also how they say it, via facial displays of emotions and vocal pitch. Candidate characteristics can shape how leaders use—and how voters react to—nonverbal cues. Drawing on role congruity expectations, we study how the use of and reactions to facial, vocal, and textual communication in political debates varies by candidate gender. Relying on full-length videos of four German federal election debates (2005–2017) and a minor party debate, we use video, audio, and text data to measure candidate facial displays of emotion, vocal pitch, and speech sentiment. Consistent with our expectations, Angela Merkel expresses less anger than her male opponents, but she is just as emotive in other respects. Combining these measures of emotional expression with continuous responses recorded by live audiences, we find that voters punish Merkel for anger displays and reward her happiness and general emotional displays.

Study Type – Prognosis (inception cohort) Level of Evidence 1b OBJECTIVES To validate the association of lymphovascular invasion (LVI) with disease recurrence and cancer-specific survival (CSS) in a multicentre cohort of patients treated with radical cystectomy (RC) for urothelial bladder cancer (UBC). PATIENTS AND METHODS We collected pathological and clinical data on 1099 lymph node-negative patients treated with RC at six German institutions. LVI was defined as the presence of tumour cells within an unequivocal endothelium-lined space in haematoxylin and eosin-stained sections. RESULTS LVI was present in 295 (26.8%) patients; the presence of LVI correlated significantly with increasing tumour stage, i.e. pT1, 65 (29.4%); pT2, 88 (31.5%); pT3 110 (31.8%); and pT4 32 (38.1%) ( P= 0.002) and grade ( P < 0.001). In univariable analysis the presence of LVI was significantly associated with reduced recurrence-free survival ( P= 0.008) and reduced CSS ( P= 0.039). On multivariable Cox regression analysis tumour stage ( P < 0.001), age (>75 vs ≥75 years; P= 0.018) and LVI ( P < 0.001) were identified as independent predictors of CSS. CONCLUSIONS Our large multicentre study confirms the independent prognostic value of LVI in patients with node-negative UBC. LVI can be regarded as a surrogate variable for lymphatic micrometastasis in node-negative UBC. Assessment of LVI might improve the selection of patients who are likely to benefit from adjuvant therapy after RC. The identification of factors involved in the process of LVI could reveal new therapeutic targets for UBC. [ABSTRACT FROM AUTHOR]

Abstract: Since hydromorphology in about 80% of German streams and rivers is degraded to a high degree, increased efforts in hydromorphological renaturalization are necessary. A measurement of the success of the first realized projects shows that improvement in stream morphology has a remarkably positive influence on aquatic ecology. An example of a restored stretch of a lowland stream in Saxony-Anhalt is used to describe the possibilities of success measurement programs for improvement of poor renaturalization. Therefore, a combined morphological and hydrobiological approach was developed. An integrated ecological assessment is possible by using the multimetric index EQI
M (Ecological Quality Index using benthic Macroinvertebrates) and the GFI (German Fauna Index). The latter represents a tolerance measure to evaluate the hydromorphological status of a site by using certain taxa that indicate either positive or negative physical attributes. To consider the special characteristics of the stream in its landscape unit, specific reference conditions (‘Leitbild’) were defined for macroinvertebrate communities by sampling comparable but undisturbed streams in the same landscape unit. Only the combination of biological indices, hydromorphological mapping and comparison to the reference status allows for an expressive evaluation of renaturalization measures and precise conclusions for their improvement.

Background: Medical schools globally now use objective structured clinical examinations (OSCEs) for assessing a student's clinical performance. In Germany, almost all of the 36 medical schools have incorporated at least one summative OSCE into their clinical curriculum. This nationwide study aimed to examine whether the introduction of OSCEs shifted studying time. The authors explored what resources were important for studying in preparation for OSCEs, how much time students spent studying, and how they performed; each compared to traditionally used multiple choice question (MCQ) tests. Methods: The authors constructed a questionnaire comprising two identical sections, one for each assessment method. Either section contained a list of 12 study resources requesting preferences on a 5-point scale, and two open-ended questions about average studying time and average grades achieved. During springtime of 2015, medical schools in Germany were asked to administer the web-based questionnaire to their students in years 3–6. Statistical analysis compared the responses on the open-ended questions between the OSCE and MCQs using a paired t-test. Results: The sample included 1131 students from 32 German medical schools. Physical examination courses were most important in preparation for OSCEs, followed by class notes/logs and the skills lab. Other activities in clinical settings (e.g. medical clerkships) and collaborative strategies ranked next. Conversely, resources for gathering knowledge (e.g. lectures or textbooks) were of minor importance when studying for OSCEs. Reported studying time was lower for OSCEs compared to MCQ tests. The reported average grade, however, was better on OSCEs. Conclusions: The study findings suggest that the introduction of OSCEs shifted studying time. When preparing for OSCEs students focus on the acquisition of clinical skills and need less studying time to achieve the expected level of competence/performance, as compared to the MCQ tests.

Introduction and objectives: The purpose of this study was to estimate the health-related quality of life (HRQoL) following modified ureterosigmoidostomy (Mainz Pouch II) urinary diversion.Materials and methods: Between March 1995 and February 2003 the procedure was performed in 83 patients (67 male and 16 female, median age 62 years, range 2–78 years) at the Departments of Urology in Bonn, Germany, and Pesaro, Italy. Patients were asked during follow-up to complete a validated, cancer-specific quality of life questionnaire, namely the EORTC QLQ C-30 Version 3. Forty-one patients (29 male, 12 female) completed the QLQ C-30. Twenty-eight patients were dead at the time of the study and 14 patients were lost to follow-up. A non-validated questionnaire was answered by 31 patients (75%) of the Bonn series to determine specific urinary diversion items. Mean follow-up time was 24.4 months (6 to 84 months).Results: No statistically significant differences (p < 0.05) in functional and symptom scales or global health status were detected between males and females. All scales but diarrhea showed good results and the outcome was comparable to health-related quality of life in a reference population of Germany. Continence rate was 100% at daytime; all but one patient had to get up for urination at night. About one third of the patients have to urinate more than six times during the day and more than three times during the night. Sixty-three percent of the patients in the Bonn series were able to distinguish between stool and urine.Conclusion: The Mainz Pouch II serves as a satisfying continent urinary diversion for both sexes in selected patients in terms of quality of life. Patients seem to adapt to their “individual” form of urinary diversion. In terms of continence modified ureterosigmoidostomy can lead to daytime continence rate of 100%. The relatively high voiding frequency during night-time was not felt to be disturbing by the patients and demonstrates the adaptability of the patients. [Copyright &y& Elsevier]

- Abstract
Background: Surgical resection is considered to be of purely diagnostic value in aggressive lymphoma. Evidence for an impact on outcome is scant and restricted to retrospective observations., Methods: In the "Positron Emission Tomography-guided Therapy of Aggressive non-Hodgkin Lymphomas" (PETAL) trial, patients with a negative baseline positron emission tomography (PET) scan were documented in a prospective observational substudy. Baseline PET-negative patients with the absence of lymph node enlargement on computed tomography and a negative bone marrow biopsy were considered to have undergone complete lymphoma resection., Results: Eighty-two of 1,041 patients (7.9%) had a negative baseline PET scan, and 67 were included in this analysis. All were treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), plus rituximab for CD20-positive lymphomas. Among 52 patients with diffuse large B-cell lymphoma (DLBCL), 48 had completely resected disease. Their outcome tended to be better than that of 115 baseline PET-positive stage I DLBCL patients treated in the main part of the PETAL trial (2-year progression-free survival 92.7% [95% confidence interval 84.7-100] versus 88.4% [82.5-94.3], P = .056; 2-year overall survival 92.7% [84.7-100] versus 93.7% [89.2-98.2], P = .176), but this was restricted to patients below the age of 60 years (2-year progression-free survival 100% versus 92.2% [84.8-99.6], P = .031; 2-year overall survival 100% versus 95.9% [90.2-100], P = .075). In peripheral T-cell lymphoma, eight of 11 patients had completely resected disease. In contrast to DLBCL, complete resection was not associated with improved outcome compared to the control., Conclusion: Young patients with early stage DLBCL may benefit from complete lymphoma resection prior to immunochemotherapy., (© 2020 The Authors.

- Abstract
Background: Research shows disparities in cancer outcomes by ethnicity or socio-economic status. Therefore, it is the aim of our study to perform a matched-pair analysis which compares the outcome of German and non-German (in the following described as 'foreign') cancer patients being treated at the Center for Integrated Oncology (CIO) Köln Bonn at the University Hospital of Bonn between January 2010 and June 2016., Methods: During this time, 6314 well-documented patients received a diagnosis of cancer. Out of these patients, 219 patients with foreign nationality could be matched to German patients based on diagnostic and demographic criteria and were included in the study. All of these 438 patients were well characterized concerning survival data (Overall survival, Progression-free survival and Time to progression) and response to treatment., Results: No significant differences regarding the patients' survival and response rates were seen when all German and foreign patients were compared. A subgroup analysis of German and foreign patients with head and neck cancer revealed a significantly longer progression-free survival for the German patients. Differences in response to treatment could not be found in this subgroup analysis., Conclusions: In summary, no major differences in survival and response rates of German and foreign cancer patients were revealed in this study. Nevertheless, the differences in progression-free survival, which could be found in the subgroup analysis of patients with head and neck cancer, should lead to further research, especially evaluating the role of infectious diseases like human papillomavirus (HPV) and Epstein-Barr virus (EBV) on carcinogenesis and disease progression.

- Abstract
Objective: Side effects are a concern during psychostimulant treatment. Unfortunately, many previous studies only investigated short-term effects of psychostimulants in laboratory settings which lack clinical daily routines. Methods: We examined 1042 patient records of patients with attention deficit hyperactivity disorder (ADHD) who were referred to a pediatric-psychiatry practice over 12 years. Data analysis was based on 466 children with ADHD who were newly treated with psychostimulants and who were not in treatment for elevated blood pressure. We analysed blood pressure percentiles, heart rate and BMI percentiles. Results: There was a decrease in systolic and diastolic blood pressure percentiles. Heart rate was not affected. BMI slightly declined in girls. Conclusions: In general psychostimulants were safe. To further elucidate negative effects of psychostimulants, long-term controlled and randomized studies in naturalistic settings are of interest.

- Abstract
Objective: The objective structured clinical examination (OSCE) has become widely accepted as a form of assessment in medical education. At the same time, the more traditional multiple choice question (MCQ) examinations remain a central modality of student assessment. This pilot survey aimed to investigate students' perceptions about the benefits of the OSCE and MCQs to yield data supporting the implementation of this assessment strategy into the national medical licensing examination in Germany. Methods: A questionnaire was delivered electronically to 34 German medical schools. Students in years 3-6 were invited to rate 11 items about objectives of good medical assessment. All items were presented for both the OSCE and MCQs using a 5-point Likert Scale (1=strongly disagree to 5=strongly agree). Factor analysis was used to identify underlying components in the ratings. Average scores of items that belonged to a component were computed. Results: Data analysis included 1,082 students from 32 medical schools. For the OSCE, factor analysis revealed two components, which were labelled "educational impact" and "development of clinical competence". The average scores of items were 3.37 and 3.55, respectively. For the MCQ modality, also two components emerged. These were labelled "perceived weaknesses of MCQs" and "perceived strengths of MCQs" (consisting of items such as "promotes my theoretical knowledge"). The average scores for these components were 1.85 and 3.62. Conclusion: The results of this pilot survey indicate that students consider both OSCE and MCQs as useful assessments for the purposes for which they were designed. The assessment strategy thus appears appropriate and it should be used in the national licensing examination.

- Abstract
Background: The prevalence of urolithiasis in Germany is 4.7%; its incidence has trebled in the last three decades. The risk of recurrence is 50-80%, depending on the type of stone, unless secondary prevention is instituted. Risk-adapted secondary prevention lowers this risk to 10-15%., Methods: This review is based on publications retrieved by a selective search in PubMed using the key words "urolithiasis," "urinary stones," "epidemiology," "lithogenesis," "biominerals," "risk factors," and "diagnosis, therapy, metaphylaxis." These publications were evaluated with the aid of the urolithiasis guideline of the European Association of Urology., Results: Acute renal colic can usually be diagnosed without sophisticated equipment. Stones can be dealt with by a variety of techniques depending on their size and location, including extracorporeal shock-wave lithotripsy, ureterorenoscopy, percutaneous nephrolitholapaxy, and open surgery. Most ureteric stones of diameter up to 5 mm pass spontaneously. 75% of patients have no complications. The basic evaluation needed for secondary prevention can be carried out by any physician on an ambulatory basis. In the 25% of patients who have complications, a more extensive interdisciplinary evaluation of metabolic parameters should be performed in a clinical center for urinary stones., Conclusion: Urolithiasis has many causes and can be treated in many different ways. An extensive metabolic work-up is often necessary for secondary prevention. The various treatment options must be considered for their suitability in each individual patient. Robust data are now available on surgical and interventional methods, but there are as yet no high-quality trials of secondary prevention. Further research should concentrate on the etiology and pathogenesis of urolithiasis.

- Abstract
Objectives: To identify the prognostic impact of venous tumour thrombus (VTT) in locally advanced renal cell carcinomas (RCCs). To further differentiate the clinical course of patients with VTT who have similar clinicopathological characteristics., Patients and Methods: We determined the VTT consistency (solid vs friable) in a retrospective cohort of 200 patients with RCC who had undergone nephrectomy between 1994 and 2011. We examined the correlation of VTT consistency in these patients with clinical and pathological variables., Results: A total of 65% of the patients had solid VTT and 35% had friable VTT, which has a significantly lower amount of cell-cell adhesion molecules and connective tissue than solid VTT. We found that friable VTT was associated with advanced pT stage, higher VTT level, papillary RCC subtype and a lower age. Patients with friable VTT had a significantly shorter median overall survival than those with solid VTT (29 vs 89 months), but VTT consistency was not found to be an independent predictor of patients' survival in the multivariate Cox analysis. We found that VTT consistency was an independent significant predictor of overall survival in patients without evidence of distant and nodal metastases (N = 119)., Conclusions: The VTT consistency is caused by the tumour and not by different surgical handling. Friable VTT is an important adverse prognostic predictor of overall survival in patients with non-metastatic RCC., (© 2013 The Authors. BJU International © 2013 BJU International.)

- Abstract
Background: Cabazitaxel (Cbz) is an approved second-line treatment in metastatic castration-resistant prostate cancer (mCRPC) following docetaxel therapy with a significant survival benefit compared with mitoxantrone. However, grade 3/4 toxicities were reported in 82% of patients., Objective: To report on the safety results of mCRPC patients treated within a compassionate-use programme in Germany., Design, Setting, and Participants: A total of 111 patients with a mean age of 67.9 yr (range: 49-81 yr) and progressive mCRPC were included. Patients had received a mean number of 12.7 ± 10.8 cycles (range: 6-69 cycles) of docetaxel with a mean cumulative dose of 970.9 mg/m(2); mean time from last docetaxel application to progression was 6.95 mo (range: 2-54 mo). Of the patients, 31.5% progressed by prostate-specific antigen (PSA) increase only; the remainder had a combination of PSA increase and clinical progression., Intervention: Cbz at a dosage of 25mg/m(2) intravenously every 3 wk combined with 5mg of oral prednisone twice a day., Outcome Measurements and Statistical Analysis: Treatment-associated toxicity was the primary study end point; progression-free and overall survival were secondary end points. A descriptive statistical analysis was performed., Results and Limitations: Patients received a mean number of 6.5 ± 2.2 cycles of Cbz and a mean cumulative dose of 160.3 ± 51.5mg/m(2). Grade 3 and 4 treatment-emergent adverse events were recorded in 34 patients (30.6%) and 18 patients (16.2%), respectively. Grade 3/4 anaemia, neutropenia, and thrombocytopenia were reported in 4.5%, 7.2%, and 0.9% of the patients, respectively. Neutropenic fever was reported in 1.8% of the patients. Grade 3/4 gastrointestinal toxicity was identified in 4.5% of the patients. Three patients died because of Cbz-related toxicity. Granulocyte colony-stimulating growth factors were used in 17.1% of patients. The limitations are due to the nonrandomised nature of the trial., Conclusions: Treatment with Cbz is tolerable and is associated with a low incidence of serious adverse events in a real-world patient population with CRPC. The outcome of serious adverse events can be minimised with proactive treatment management and conscientious monitoring., (Copyright © 2012 European Association of Urology. Published by Elsevier B.V.

- Abstract
Background: Outcome of patients with urothelial carcinoma of the bladder (UCB) varies between sexes. Although overall incidence is higher in men, cancer-specific survival (CSS) has been suggested to be lower in women. Although the former effect is attributed to greater exposure to carcinogens in men, the latter has not been elucidated., Objectives: The aim of the study was to identify sex-specific outcomes based on one of the largest databases of patients with UCB who underwent radical cystectomy (RC)., Methods: This retrospective multicenter series comprised 2483 patients in Stage M0 who underwent RC for UCB from 1989 to 2008; 20.4% of patients were women. The impact of sex on CSS in the entire study group and in specific subgroups was analyzed. The median follow-up time was 42 months (interquartile range, 21-79)., Results: Histopathologic criteria of pathologic tumor (pT), pathologic nodal (pN), grade, lymphovascular invasion (LVI), and associated carcinoma in situ (CIS) of the study did not differ between sexes. The percentage of female patients increased over time. Five-year CSS in female patients was significantly lower than in male patients (60% vs 66%; P = 0.005). In multivariate analysis adjusted to other covariates, tumor stage ≥pT3 (hazard ratio [HR] = 2.44; P < 0.001), positive pN status (HR = 1.91; P < 0.001), LVI (HR = 1.48; P < 0.001), lower count of lymph nodes removed (HR = 0.98; P = 0.002), older age (HR = 1.01; P < 0.001), and female gender (HR = 1.26; P = 0.011) had an independent impact on CSS. Deterioration of CSS in female patients was pronounced when LVI was present (HR = 1.57; P < 0.001) and when RC was performed in the earlier time period (HR = 2.44; P < 0.001). However, women showed significantly lower perioperative mortality (within 90 days after RC) compared with men., Conclusions: After RC for UCB, cancer-specific mortality was higher in female patients; this disadvantage was more pronounced in earlier time periods. In addition, worse outcome of women with verified LVI was shown to be comparable with men. These findings were suggestive of different tumor biology and potentially unequal access to timely RC in earlier time periods because of reduced awareness of UCB in women. Further studies are required to improve UCB outcome in both sexes, notably in female patients., (Copyright © 2012 Elsevier HS Journals, Inc. All rights reserved.)

- Abstract
Purpose: To evaluate the feasibility and safety of thulium:yttrium-aluminium-garnet laser vapoenucleation of the prostate (ThuVEP) in patients with chronic anticoagulation and bleeding disorders., Methods: We retrospectively analyzed the clinical data (transfusion rate, hemoglobin changes, residual urine, bleeding complications, complications and residual urine) of patients with chronic anticoagulation and bleeding disorders treated with ThuVEP. Anticoagulation was not paused for surgery., Results: We identified 39 patients who fulfilled the inclusion criteria (32 with chronic anticoagulation, 3 with bleeding disorder, and 4 with both). Mean preoperative hemoglobin was 12.9 g/l; the postoperative hemoglobin was 11.7 g/l. One patient received a blood transfusion. Mean residual urine was 166 ml preoperatively and 47 ml postoperatively, respectively; spontaneous voiding postoperatively was feasible in 36 patients. During follow-up, 5 patients suffered from gross hematuria, which was treated conservatively., Conclusions: ThuVEP is a safe procedure in patients with therapeutic anticoagulation, bleeding disorders and platelet aggregation inhibitor medication., (Copyright © 2012 S.

- Abstract
Background: The prognosis for patients with lymph node (LN)-positive bladder cancer (BCa) is likely affected by the extent of lymphadenectomy in radical cystectomy (RC) cases. Specifically, the prognostic significance of the LN density (ratio of positive LNs to the total number removed) has been demonstrated., Objective: To evaluate the prognostic signature of lymphadenectomy variables, including the LN density, for a large, multicentre cohort of RC patients with LN-positive BCa., Design, Setting, and Participants: The clinical and histopathologic data from 477 patients with LN-positive urothelial BCa (pN1-2) were analysed. The median follow-up period for all living patients was 28 mo., Measurements: Multivariable Cox regression analysis was used to test the effect of various pelvic lymph node dissection (PLND) variables on cancer-specific survival (CSS) based on colinearity in various models., Results and Limitations: The median number of LNs removed was 12 (range: 1-66), and the median number of positive LNs was 2 (range: 1-25). Two hundred ninety (60.8%) of the patients presented with stage pN2 disease. The median and mean LN density was 17.6% and 29% (range: 2.3-100), respectively, where 268 (56.2%) and 209 (43.8%) patients exhibited am LN density of ≤20% and >20%, respectively. In separate multivariable Cox regression models adjusted for age, sex, pTN stage, grade, associated Tis, and adjuvant chemotherapy, the interval-scaled LN density (hazard ratio [HR]: 1.01; p=0.002) and the LN density, ordinal-scaled by 20% (HR: 1.65; p<0.001) exhibit independent effects on CSS. In addition, an independent contribution appears from the pT but not the pN stage. Limitations include surgeon selection bias when determining the extent of lymphadenectomy., Conclusions: Our results support the prognostic relevance of LN density in patients with LN-positive BCa, where a threshold value of 20% stratifies the population into two prognostically distinct groups. Before LN density is integrated into the clinical decision-making process, these results should be validated by prospective studies with defined LN templates and standardised histopathologic methods., (Copyright © 2011 European Association of Urology.

- Abstract
Background: The highly vascular nature of renal carcinoma cells suggests that inhibition of angiogenesis may be beneficial in this disease. Thalidomide has been described as inhibitor of the fibroblast growth factor (FGF) and the vascular endothelial growth factor (VEGF). Therefore and in consideration of the promising response rates of the combination of IL-2, IFN-alpha and 5-FU [1] in metastatic renal cancer, we found it reasonable to test the combination of 5-FU and thalidomide. Thus, we conducted a phase I trial to determine safety, side effects and responses to such a treatment., Methods: Patients with metastasized renal cell cancer after nephrectomy and progress after IL-2 and interferon treatment, received oral 5-FU at a dose of 1250 mg/qm(2) twice a day for two weeks, then after pausing a week, the oral application was restarted. In addition, oral thalidomide was applied constantly at a maximum dose of 400 mg/d. The combined therapy was given for three months. The primary endpoint was duration until disease progression, the secondary endpoint the response to treatment. Response was determined by CT scans three months after the end of treatment., Results: In total, 12 male patients participated in the trial and received the combined oral therapy. Concerning clinical response, one mixed response (8%), a stable disease in 4/12 patients (33%) and progression was seen in 7 patients (58%). The survival from the start of the therapy showed a median of 21 months with three patients being alive. At present, the longest survival after the therapy is 51 months., Conclusions: The combination of oral 5-FU and thalidomide showed clinical response with tolerable side effects. Further studies will be required to assess the outcome of this treatment regimen.
