Schweigen ist Silber, Reden ist Gold : sexuelle Belästigung am Arbeitsplatz gegenüber dem Pflegepersonal - ein Literaturreview

Einleitung: Bereits im 19. Jahrhundert ist sexuelle Belästigung gegenüber Pflegenden als Phänomen bekannt und stellt damals wie heute ein Tabuthema dar. Weltweit sind rund 25% der Pflegekräfte betroffen. Sensibilisieren und Anstoss zu einem wirkungsvollen Umgang geben, ist das Ziel dieser Bachelorthesis. Fragestellung: Was sagt die Literatur über sexuelle Belästigung gegenüber Pflegenden am Arbeitsplatz, ausgehend von Patientinnen und Patienten? Methode: Zur Beantwortung der Fragestellung erfolgt im Zeitraum von August bis Oktober 2019 eine systematisierte Literaturrecherche auf medizinisch-pflegerischen Datenbanken. Ergebnisse: In acht Studien, unterschiedlichen Designs, wird die Dimension des Phänomens bestätigt. Die Belästigung reicht von sexuell motiviertem Anstarren, über Bemerkungen bis zu eindeutigen Berührungen. Mit 60% ist das Patientengut als Täterschaft übervertreten. Pflegende reagieren mit Rückzug, Vermeidung, Ablenkung oder Verweigerung. Oft werden sexuelle Übergriffe als Teil der Arbeit angesehen und nicht gemeldet. Sie haben negative Auswirkungen auf das Pflegepersonal, Institutionen und das Patientengut. Betroffene Pflegende kämpfen mit psychischen und physischen Folgen wie Angstzustände, Hoffnungslosigkeit, Herzklopfen oder Zittern. Schlussfolgerung: Die Handlungsstrategien müssen durch Edukation, Öffentlichkeitsarbeit und politisches Engagement professionalisiert werden, um eine Reduktion des Phänomens zu erwirken. Ein Appell richtet sich an die schweizerischen Gewerkschaften und Organisationen. Die Politik ist gefordert, das Thema als relevant anzusehen

Patients’ sexual harassment of nurses and nursing students : a cross-sectional study

Background: Workplace sexual harassment towards nurses is a global phenomenon: approximately one quarter of all nurses are affected by sexual harassment. The extent and type of sexual harassment vary greatly depending on the country, culture, level of education, and care setting. Notably, patients are amongst the main perpetrators. Importantly, sexual harassment has serious consequences on nurses’ health and work performance. Objective: This study examined the prevalence of patients’ workplace sexual harassment towards nurses and nursing students at a University of Applied Sciences in Switzerland. Design: A quantitative cross-sectional descriptive correlational design was used. Setting: The survey was conducted at the university’s Institute of Nursing under the Department of Health. Participants: Nurses and nursing students who were studying or attending a continuing education programme and had worked as a nurse with direct contact with patients in the last 12 months could qualify as participants. A final sample of 251 participants was used for the analysis. Methods: Data were collected using the ‘Sexually Harassing Behaviour Questionnaire from an extraorganizational perspective’. Preliminary analysis involved computing the percentage and absolute frequencies, mean scores, standard deviations, and ranges. The hypotheses were tested using non-parametric tests, such as the Wilcoxon test for two independent samples, Spearman correlation test, and Kruskal-Wallis H test. Results were considered statistically significant at alpha < 0.05. Results: Most participating nurses were women (88.5%) and worked in adult acute care (54.2%). The mean age was 25.5 (SD = 7.5) years. On average, they had worked in the nursing profession for 7 years. 17.1% of the participants had received training on sexual harassment. Overall, 95.6% of the participants reported experiencing sexual harassment of any type at least once in the last 12 months. The most common type of harassment was verbal sexual harassment. Notably, sexual harassment was statistically significantly more frequent the younger the nurses were [rs = -0.13, p = 0.046]. Furthermore, it was statistically significantly more prevalent in adult acute care than in paediatrics [H (10) = 18.4; p = 0.048; Cohen’s d = 0.4]. Conclusions: Patients’ sexual harassment of participant nurses and nursing students is highly common. The high prevalence of sexual harassment and low number of nurses who have received training on sexual harassment demonstrate the need for initiatives to address this phenomenon in the basic education of nurses. Furthermore, evidence-based interventions against sexual harassment in the nursing profession are needed

Correlated-photon imaging at 10 volumetric images per second

The correlation properties of light provide an outstanding tool to overcome the limitations of traditional imaging techniques. A relevant case is represented by correlation plenoptic imaging (CPI), a quantum-inspired volumetric imaging protocol employing spatio-temporally correlated photons from either entangled or chaotic sources to address the main limitations of conventional light-field imaging, namely, the poor spatial resolution and the reduced change of perspective for 3D imaging. However, the application potential of high-resolution imaging modalities relying on photon correlations is limited, in practice, by the need to collect a large number of frames. This creates a gap, unacceptable for many relevant tasks, between the time performance of correlated-light imaging and that of traditional imaging methods. In this article, we address this issue by exploiting the photon number correlations intrinsic in chaotic light, combined with a cutting-edge ultrafast sensor made of a large array of single-photon avalanche diodes (SPADs). This combination of source and sensor is embedded within a novel single-lens CPI scheme enabling to acquire 10 volumetric images per second. Our results place correlated-photon imaging at a competitive edge and prove its potential in practical applications.Comment: 13 pages, 6 figure

Prognostic significance of cyclooxygenase-2 pathway and angiogenesis in head and neck squamous cell carcinoma

Prostaglandins play a critical role in tumor development and growth by regulating numerous biologic processes, including tumor angiogenesis, with clear prognostic and therapeutic implications. The aim of this study was to investigate the prognostic relevance of cyclooxygenase-2 (COX-2) pathway activation in head and neck squamous cell carcinoma (HNSCC). COX-2 activity was analyzed in 52 consecutive patients by assessing protein expression and prostaglandin E2(PgE2) levels and was then correlated to vascular endothelial growth factor (VEGF) expression and tumor angiogenesis. We evaluated the prognostic impact of these parameters by Kaplan-Meier and Cox survival analysis. COX-2 expression by tumor cells was closely correlated to VEGF expression and to tumor vascularization. According to Kaplan-Meier analysis, patients with COX-2 tumor overexpression and with higher PgE2tumor levels had significantly shorter overall survival estimates (P = 0.022 and P = 0.033, respectively). Analogously, patients with more-vascularized tumors had worse survival than those with less-vascularized cancers (P = 0.032). Cox multivariate analysis demonstrated that the most significant prognostic factors were presence of lymph node metastasis, tumor vascularization, COX-2 protein expression, and PgE2tumor levels. This study demonstrates a close correlation between COX-2 pathway, VEGF expression, and tumor angiogenesis in HNSCC. In addition, COX-2 overexpression and higher tumor vascularization appear to predict a shorter survival in patients with head and neck cancer. Copyright 2002, Elsevier Science (USA).

Measurement of the double-differential inclusive jet cross section in proton-proton collisions at s\sqrt{s} = 5.02 TeV

International audienceThe inclusive jet cross section is measured as a function of jet transverse momentum $p_\mathrm{T}$ and rapidity $y$. The measurement is performed using proton-proton collision data at $\sqrt{s}$ = 5.02 TeV, recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 27.4 pb$^{-1}$. The jets are reconstructed with the anti-$k_\mathrm{T}$ algorithm using a distance parameter of $R$ = 0.4, within the rapidity interval $\lvert y\rvert$$\lt$ 2, and across the kinematic range 0.06 $\lt$$p_\mathrm{T}$$\lt$ 1 TeV. The jet cross section is unfolded from detector to particle level using the determined jet response and resolution. The results are compared to predictions of perturbative quantum chromodynamics, calculated at both next-to-leading order and next-to-next-to-leading order. The predictions are corrected for nonperturbative effects, and presented for a variety of parton distribution functions and choices of the renormalization/factorization scales and the strong coupling $\alpha_\mathrm{S}$
