In Printmedien ist das klassische Inserat heute nicht mehr der einzige Weg, um Werbebotschaften zu kommunizieren. Vielfältige Werbeformen sind entstanden, die Grauzonen zwischen redaktionellen Beiträgen und Werbung dehnen sich aus. Eine systematische Aufarbeitung des Untersuchungsgegenstands Schleichwerbung in österreichischen Tageszeitungen ist jedoch bislang ausgeblieben. Diese Arbeit will daher einen Beitrag dazu leisten, diese Lücke in der kommunikationswissenschaftlichen Forschung zu schließen. Als ein interdisziplinäres Phänomen wird Schleichwerbung nicht ausschließlich über einen kommunikationswissenschaftlichen Zugang analysiert. Ebenso ist eine ökonomische Annäherung an das Thema notwendig sowie ein normativer Bezugsrahmen, der juristische Grundlagen und ethische Normen berücksichtigt. Der Untersuchungsgegenstand Schleichwerbung wird vor dem Hintergrund der zunehmenden Ökonomisierung der Medien betrachtet. Dabei werden Ursachen und Konsequenzen dieser Entwicklung, insbesondere für Journalismus und Gesellschaft, analysiert. Schleichwerbung wird als eine Folge der Ökonomisierung auf der Ebene der Medieninhalte verstanden und problematisiert. Im österreichischen Mediengesetz ist die Trennung von werbenden und redaktionellen Inhalten mit § 26 geregelt. Zudem gibt es eine freiwillige Selbstregulierung in Form von ethischen Selbstverpflichtungen. Die Ergebnisse der im Zeitraum einer künstlichen Woche in allen österreichischen Tageszeitungen durchgeführten Inhaltsanalyse machen deutlich: Die Medienrealität sieht anders aus, als die zahlreichen Regelungsversuche vermuten lassen. Demnach findet sich in fast allen Tageszeitungen Schleichwerbung. Als Schleichwerbung werden dabei Beiträge verstanden, die werbende und redaktionelle Inhalte vermischen und für den Leser irreführend sind. Die Untersuchung zeigt damit, dass es als Folge der Ökonomisierung der Medien auf der Inhaltsebene in den österreichischen Tageszeitungen zu Schleichwerbung kommt. Im Rahmen der Ergebnisinterpretation wird die Ökonomisierung jedoch nicht als einziges Erklärungsmodell beschrieben. Mögliche Erklärungsansätze liefern beispielsweise auch Aspekte der Aufmerksamkeitsökonomie. Die Arbeit schließt mit einem Fazit und stellt mögliche Konsequenzen der Untersuchungsergebnisse für Gesetzgebung, Kommunikationspraxis und Ausbildung, Selbstkontrolle sowie kommunikationswissenschaftliche Forschung zur Diskussion.Nowadays, classical advertisements are not the only way to communicate advertising messages via print media. Various forms of advertising have emerged. The undefined area between advertisements and editorial content is growing. A systematic analysis of surreptitious advertising in Austrian daily newspapers did not exist so far. Therefore the underlying thesis wants to provide a contribution in order to close this gap in communication sciences. Surreptitious advertising is an interdisciplinary phenomenon. For this reason it cannot be analysed exclusively from the perspective of communication sciences. An economic approach to the topic is necessary as well as a normative one, which considers judicial basic principles and ethic norms. Surreptitious advertising is analysed under consideration of the economisation of the media. Causes and consequences of this development, especially for journalism and society, are described. Surreptitious advertising is discussed as a consequence of the economisation at the level of editorial products. The separation of advertising and editorial content is regulated under section 26 of Austrian media law. Moreover there exists a form of voluntary self-regulation via the commitment to ethical guidelines. Based on the results of the content analysis, which covered the period of a so called artificial week in all Austrian daily newspapers, it can be noted that media reality strongly differs from the principles as laid down in the various regulations. Surreptitious advertising, defined as publications, which combine editorial and advertising contents in a, from the perspective of the reader, deceptive way, was detected in almost every daily newspaper. The analysis shows that in Austrian daily newspapers the consequences of the economisation are noted in form of surreptitious advertising. In the course of the interpretation, economisation is not brought forward as the only explication for the development outlined above. Another approach to explain surreptitious advertising is the influence of the economy of attention. The thesis closes with a conclusion and brings up to discussion possible consequences in the field of legislation, practice of communication, education, self-regulation and communication sciences
Tyrol Prostate Cancer Demonstration Project : early detection, treatment, outcome, incidence and mortality
This study aimed to evaluate the effectiveness of a well-controlled programme of early detection and treatment of prostate cancer in the population of Tyrol, Austria, where such a programme of early detection and treatment was initiated in 1988 and where prostate-specific antigen (PSA) testing was offered for free to all men aged 45-75 years from 1993. Comparison of prostate cancer mortality rates in Tyrol and the rest of Austria was accomplished through a generalized additive model. A piecewise linear change-point Poisson regression model was used to compare mortality rates in Tyrol and the rest of Austria. Standardized mortality ratios were calculated with reference to the mortality rates in 1986-1990. In all, 86.6% of eligible men have been tested at least once since 1993. Cancer deaths in Tyrol in 2005 were 54% (95% confidence interval [CI] 34-69%) lower than expected compared with 29% (95% CI 22-35%) in the rest of Austria. The decreasing trend in prostate cancer mortality was significantly greater in Tyrol compared with the rest of Austria (P = 0.001). A significant migration to lower stage disease occurred and radical prostatectomy was associated with low morbidity. In the Tyrol region where treatment is freely available to all patients, where widespread PSA testing and treatment with curative intent occurs, there was a reduction in prostate cancer mortality rates which was significantly greater than the reduction in the rest of Austria. This reduction in prostate cancer mortality is most probably due to early detection, consequent down-staging and effective treatment of prostate cancer
Potentials and limitations of real-time elastography for prostate cancer detection: a whole-mount step section analysis.
OBJECTIVES: To evaluate prostate cancer (PCa) detection rates of real-time elastography (RTE) in dependence of tumor size, tumor volume, localization and histological type.
MATERIALS AND METHODS: Thirdy-nine patients with biopsy proven PCa underwent RTE before radical prostatectomy (RPE) to assess prostate tissue elasticity, and hard lesions were considered suspicious for PCa. After RPE, the prostates were prepared as whole-mount step sections and were compared with imaging findings for analyzing PCa detection rates.
RESULTS: RTE detected 6/62 cancer lesions with a maximum diameter of 0-5 mm (9.7%), 10/37 with a maximum diameter of 6-10 mm (27%), 24/34 with a maximum diameter of 11-20 20 mm (70.6%), 14/14 with a maximum diameter of \u3e20 mm (100%) and 40/48 with a volume ≥0.2 cm(3) (83.3%). Regarding cancer lesions with a volume ≥ 0.2 cm³ there was a significant difference in PCa detection rates between Gleason scores with predominant Gleason pattern 3 compared to those with predominant Gleason pattern 4 or 5 (75% versus 100%; P = 0.028).
CONCLUSIONS: RTE is able to detect PCa of significant tumor volume and of predominant Gleason pattern 4 or 5 with high confidence, but is of limited value in the detection of small cancer lesions
Hypothesis That Urethral Bulb (Corpus Spongiosum) Plays an Active Role in Male Urinary Continence
The proximal urethral bulb in men is enlarged, surrounds the bulbous urethra, and extends dorsally towards the perineum. During intercourse engorgement takes place due to increased blood flow through the corpus spongiosum. Antegrade ejaculation is facilitated by contraction of the bulbospongiosus muscles during climax. Micturition during sexual stimulation is functionally inhibited. Supporting the bulb may indirectly facilitate continence in a certain subset of patients with postprostatectomy incontinence. During physical activity with increased abdominal pressure, reflex contraction of the pelvic floor muscles as well as the bulbospongiosus muscles occurs to support sphincter function and limit urinary incontinence. Operations to the prostate may weaken urinary sphincter function. It is hypothesized that the distal urinary sphincter may be supported indirectly by placing a hammock underneath the urethral bulb. During moments of physical stress the “cushion” of blood within the supported corpus spongiosum helps to increase the zone of coaptation within the sphincteric (membranous) urethra. This may lead to urinary continence in patients treated by a transobturator repositioning sling in patients with postprostatectomy incontinence. This paper describes the possible role of the urethral bulb in male urinary continence, including its function after retroluminal sling placement (AdVance, AdVance XP® Male Sling System, Minnetonka, USA)
Comparison of contrast enhanced color Doppler targeted biopsy to conventional systematic biology: Impact on Gleason score
Purpose: Prostate cancer grading with Gleason score is an important prognostic factor. This prospective randomized study compares ultrasound systematic biopsy vs contrast enhanced color Doppler targeted biopsy for the impact on Gleason score findings.
Materials and Methods: We examined 690 men (mean age 56 years, range 41 to 77) with a serum total prostate specific antigen of 1.25 ng/ml or greater, a free-to-total prostate specific antigen ratio less than 18% and/or a suspicious digital rectal examination. Contrast enhanced color Doppler targeted biopsies with a limited number of cores (5 or less) were performed in hypervascular areas of the peripheral zone during administration of the ultrasound contrast agent SonovueTM(Bracco, Milano, Italy). Ten systematic biopsies were obtained in a standard spatial distribution. Cancer detection rates and Gleason score were compared.
Results: Prostate cancer was identified in 221 of 690 subjects (32%) with a mean prostate specific antigen of 4.6 ng/ml (range 1.4 to 35.0). Prostate cancer was detected in 180 of 690 subjects (26%) with contrast enhanced color Doppler targeted biopsy and in 166 of 690 patients (24%) with systematic ultrasound biopsy. The Gleason score of all 180 cancers detected on contrast enhanced color Doppler targeted biopsy was 6 or higher (mean 6.8). The Gleason score of all 166 cancers detected on systematic biopsy ranged from 4 to 6 and mean Gleason score was 5.4. Contrast enhanced color Doppler targeted biopsy detected significantly higher Gleason scores compared to systematic biopsy (Wilcoxon rank sum test p \u3c0.003).
Conclusions: Contrast enhanced color Doppler targeted biopsy detected cancers with higher Gleason scores and more cancer than systematic biopsy. Therefore, contrast enhanced color Doppler seems to be helpful in the grading of prostate cancer, which is important for defining prognosis and deciding treatment
Racial differences in serum prostate-specific antigen (PSA) doubling time, histopathological variables and long-term PSA recurrence between African-American and white American men undergoing radical prostatectomy for clinically localized prostate cancer
To determine if there are significant differences in biochemical characteristics, biopsy variables, histopathological data, and rates of prostate-specific antigen (PSA) recurrence between African-American (AA) and white American (WA) men undergoing radical prostatectomy (RP), as AA men are twice as likely to die from prostate cancer than their white counterparts. PATIENTS AND METHODS We established a cohort of 1058 patients (402 AA, 646 WA) who had RP and were followed for PSA recurrence. Age, race, serum PSA, biopsy Gleason score, clinical stage, pathological stage, and PSA recurrence data were available for the cohort. The chi-square test of proportions and t -tests were used to assess basic associations with race, and log-rank tests and Cox regression models for time to PSA recurrence. Forward stepwise variable selection was used to assess the effect on the risk of PSA recurrence for race, adjusted by the other variables added one at a time. RESULTS The AA men had higher baseline PSA levels, more high-grade prostatic intraepithelial neoplasia (HGPIN) in the biopsy, and more HGPIN in the pathology specimen than WA men. The AA men also had a shorter mean (sd) PSA doubling time before RP, at 4.2 (4.7) vs 5.2 (5.9) years. However, race was not an independent predictor of PSA recurrence ( P = 0.225). Important predictors for PSA recurrence in a multivariable model were biopsy HGPIN ( P < 0.014), unilateral vs bilateral cancer ( P < 0.006), pathology Gleason score and positive margin status (both P < 0.001). CONCLUSIONS This study indicates that while there are racial differences in baseline serum PSA and incidence of HGPIN, race is not an independent risk factor for PSA recurrence. Rather, other variables such as pathology Gleason score, bilateral cancers, HGPIN and margin positivity are independently associated with PSA recurrence. The PSA doubling time after recurrence may also be important, leading to the increased mortality of AA men with prostate cancer.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/74706/1/j.1464-410X.2005.05561.x.pd
Seasonal variations in the diagnosis of testicular germ cell tumors: a national cancer registry study in austria
SIMPLE SUMMARY: Seasonal variations in cancer diagnosis could already be demonstrated in prostate and breast cancer. The reasons for this observed seasonal pattern are still unclear. The health care system or other determinants such as the protective function of vitamin D3 in carcinogenesis could be assumed as one explanation. Testicular germ cell tumors are the most common developed malignancy among young men. The aim of our study was to investigate, for the first time, the seasonal variations in the clinical diagnosis of testicular germ cell tumors. We have been able to confirm that the frequency of monthly newly diagnosed cases of testicular cell tumors in Austria has a strong seasonality, with a significant reduction in the tumor incidence during the summer months and an increase during the winter months. ABSTRACT: We conducted a retrospective National Cancer Registry study in Austria to assess a possible seasonal variation in the clinical diagnosis of testicular germ cell tumors (TGCT). In total, 3615 testicular cancer diagnoses were identified during an 11-year period from 2008 to 2018. Rate ratios for the monthly number of TGCT diagnoses, as well as of seasons and half-years, were assessed using a quasi-Poisson model. We identified, for the first time, a statistically significant seasonal trend (p < 0.001) in the frequency of monthly newly diagnosed cases of TGCT. In detail, clear seasonal variations with a reduction in the tumor incidence during the summer months (Apr–Sep) and an increase during the winter months (Oct–Mar) were observed (p < 0.001). Focusing on seasonality, the incidence during the months of Oct–Dec (p = 0.008) and Jan–Mar (p < 0.001) was significantly higher compared to the months of Jul–Sep, respectively. Regarding histopathological features, there is a predominating incidence in the winter months compared to summer months, mainly concerning pure seminomas (p < 0.001), but not the non-seminoma or mixed TGCT groups. In conclusion, the incidence of TGCT diagnoses in Austria has a strong seasonal pattern, with the highest rate during the winter months. These findings may be explained by a delay of self-referral during the summer months. However, the hypothetical influence of vitamin D3 in testicular carcinogenesis underlying seasonal changes in TGCT diagnosis should be the focus of further research
Suitability of PSA-detected localised prostate cancers for focal therapy: Experience from the ProtecT study
This article is available through a Creative Commons Attribution-NonCommercial-Share Alike 3.0 Unported License. Copyright @ 2011 Cancer Research UK.Background: Contemporary screening for prostate cancer frequently identifies small volume, low-grade lesions. Some clinicians have advocated focal prostatic ablation as an alternative to more aggressive interventions to manage these lesions. To identify which patients might benefit from focal ablative techniques, we analysed the surgical specimens of a large sample of population-detected men undergoing radical prostatectomy as part of a randomised clinical trial. Methods: Surgical specimens from 525 men who underwent prostatectomy within the ProtecT study were analysed to determine tumour volume, location and grade. These findings were compared with information available in the biopsy specimen to examine whether focal therapy could be provided appropriately. Results: Solitary cancers were found in prostatectomy specimens from 19% (100 out of 525) of men. In addition, 73 out of 425 (17%) men had multiple cancers with a solitary significant tumour focus. Thus, 173 out of 525 (33%) men had tumours potentially suitable for focal therapy. The majority of these were small, well-differentiated lesions that appeared to be pathologically insignificant (38–66%). Criteria used to select patients for focal prostatic ablation underestimated the cancer's significance in 26% (34 out of 130) of men and resulted in overtreatment in more than half. Only 18% (24 out of 130) of men presumed eligible for focal therapy, actually had significant solitary lesions. Conclusion: Focal therapy appears inappropriate for the majority of men presenting with prostate-specific antigen-detected localised prostate cancer. Unifocal prostate cancers suitable for focal ablation are difficult to identify pre-operatively using biopsy alone. Most lesions meeting criteria for focal ablation were either more aggressive than expected or posed little threat of progression.National Institute for Health Researc
Prostate-specific antigen testing in Tyrol, Austria: prostate cancer mortality reduction was supported by an update with mortality data up to 2008
Objectives: The objective of this study was to update an in-depth analysis of the time trend for prostate cancer (PCA) mortality in the population of Tyrol by 5 years, namely to 2008. In Tyrol, prostate-specific antigen (PSA) tests were introduced in 1988/89; more than three-quarters of all men in the age group 45–74 had at least one PSA test in the past decade. Methods: We applied the same model as in a previous publication, i.e., an age-period-cohort model using Poisson regression, to the mortality data covering more than three decades from 1970 to 2008. Results: For Tyrol from 2004 to 2008 in the age group 60+ period terms show a significant reduction in prostate cancer mortality with a risk ratio of 0.70 (95% confidence interval 0.57, 0.87) for Tyrol, and for Austria excluding Tyrol a moderate reduction with a risk ratio of 0.92 (95% confidence interval 0.87, 0.97), each compared to the mortality rate in the period 1989–1993. Conclusions: This update strengthens our previously published results, namely that PSA testing offered to a population at no charge can reduce prostate cancer mortality. The extent of mortality reduction is in line with that reported in the other recent publications. However, our data do not permit us to fully assess the harms associated with PCA screening, and no recommendation for PSA screening can be made without a careful evaluation of overdiagnosis and overtreatment
