A descriptive cross-sectional study of cholera at Kakuma and Kalobeyei refugee camps, Kenya in 2018
(2020)
Introduction: cholera is a significant public health concern among displaced populations. Oral cholera vaccines are safe and can effectively be used as an adjunct to prevent cholera in settings with limited access to water and sanitation. Results from this study can inform future consideration for cholera vaccination at Kakuma and Kalobeyei.
Methods: a descriptive cross-sectional study of cholera cases at Kakuma refugee camp and Kalobeyei integrated settlement was carried out between May 2017 to May 2018 (one year). Data were extracted from the medical records and line lists at the cholera treatment centres.
Results: the results found 125 clinically suspected and confirmed cholera cases and one related death (CFR 0.8%). The cumulative incidence of all cases was 0.67 (95% CI=0.56-0.80) cases/1000 persons. Incidence of cholera was higher in children under the age of five 0.94(95% CI=0.63-1.36) cases/1000 persons. Children aged <5 years showed 51% increased risk of cholera compared to those aged ≥5 years (RR=1.51; 95% CI=1.00-2.31, p=0.051). Individuals from the Democratic Republic of Congo had nearly 9-fold risk of reporting cholera (RR=8.62; 95% CI=2.55-37.11, p<0.001) while individuals from South Sudan reported 7 times risk of cholera case compared to those from Somalia (RR=7.39; 95% CI=2.78-27.73, p<0.001).
Conclusion: in addition to the improvement of water, sanitation and hygiene (WaSH), vaccination could be implemented as a short-medium term measure of preventing cholera outbreaks. Age, country of origin and settlement independently predicted the risk of cholera.
Background:
Hereditary angioedema (HAE) is a rare genetic disease and characterized by clinical features such as paroxysmal, recurrent angioedema of the skin, the gastrointestinal tract, and the upper airways. Swelling of the skin occurs primarily in the face, extremities and genitals. Gastrointestinal attacks are accompanied by painful abdominal cramps, vomiting and diarrhea. Due to the low prevalence and the fact that HAE patients often present with rather unspecific symptoms such as abdominal cramps, the final diagnosis is often made after a long delay. The aim of this German-wide survey was to characterize the period between occurrence of first symptoms and final diagnosis regarding self-perceived health, symptom burden and false diagnoses for patients with HAE.
Results:
Overall, 81 patients with HAE were included and participated in the telephone-based survey. Of those, the majority reported their current health status as “good” (47.5%) or “very good” (13.8%), which was observed to be a clear improvement compared to the year before final diagnosis (“good” (16.3%), “very good” (11.3%)). Edema in the extremities (85.2%) and in the gastrointestinal tract (81.5%) were the most currently reported symptoms and occurred earlier than other reported symptoms (mean age at onset 18.1 and 17.8 years, respectively). Misdiagnoses were observed in 50.6% of participating HAE patients with appendicitis and allergy being the most frequently reported misdiagnoses (40.0 and 30.0% of those with misdiagnosis, respectively). Patients with misdiagnosis often received mistreatment (80.0%) with pharmaceuticals and surgical interventions as the most frequently carried out mistreatments (65.6 and 56.3% of those with mistreatment, respectively). The mean observed diagnostic delay was 18.1 years (median 15.0 years). The diagnostic delay was higher in older patients and index patients.
Conclusions:
This study showed that self-perceived status of health for patients is much better once the final correct diagnosis has been made and specific treatment was available. Further challenge in the future will still be to increase awareness for HAE especially in settings which are normally approached by patients at occurrence of first symptoms to assure early referral to specialists and therefore increase the likelihood of receiving an early diagnosis.
A novel method has been implemented to prepare metal oxide nanopowders covered with known quantities of adsorbed water; we subsequently studied the γ-radiolysis of ZrO2 nanopowders covered with H2O layers. H2 yields from the adsorbed water radiolysis are of importance in multiple industrial contexts – the nuclear industry being a prime example. Measured H2 yields at water coverages of just below and above one monolayer are around 350 times greater than for neat water, but these yields decrease rapidly with increasing water loading of the ZrO2 nanoparticles, approaching the yield of bulk water at coverages of tens of water layers. The observed plateau of the yields at 0.5 to 2.0 monolayers coverage can be explained by the ease with which electronic excitations in the ZrO2 can be transferred across the interface to the first one or two adsorbed water layers. However, with increasing water loading, energy transfer to water layers further away from the interface becomes less efficient, and above ~30 water layers, most of the water is not affected by any exciton formation in the ZrO2.
A study to assess the knowledge and attitude towards HIV of pharmacy students from Mumbai university
(2020)
Background: India is the biggest HIV epidemic in the world. The role of a pharmacist is pivotal in educating the general masses. The aim of the study was to determine the knowledge and attitude of pharmacy students from University of Mumbai.
Methods: A cross-sectional study was conducted in University of Mumbai during February-March 2020. Therein, 307 students (214: females and 94: males) participated in the study. The questionnaire was distributed in the classroom and data was collected by means of Google-forms. Furthermore, the data was analysed using IBM SPSS version 23.
Results: The participants demonstrated good knowledge (84%) and attitude (76%) score. With respect to knowledge score, no significant difference was observed except for responses of two questions, aim of the antiretroviral therapy (ART) and Avoidance of sexual intercourse can decrease the risk of HIV. With respect to attitude score, Volunteering to work at an institute for the welfare of HIV patients showed a significant difference.
Conclusion: The current study showed that there were no misconceptions or negative attitude regarding HIV among the students. However, a study with greater sample size must be conducted across India for further investigation.
Background: We sought to develop and test an objective scorecard-based system for assessing and categorizing available research sites in Lassa fever-affected countries based on their preparedness and capability to host Lassa fever vaccine clinical trials.
Methods: We mapped available clinical research sites through interrogation of online clinical trial registries and relevant disease-based consortia. A structured online questionnaire was used to assess the capability of clinical trial sites to conduct Lassa fever vaccine clinical trials. We developed a new scoring template by allocating scores to questionnaire parameters based on perceived importance to the conduct of clinical trials as described in the WHO/TDR Global Competency Framework for Clinical Research. Cutoff points of 75% and 50% were used to categorize sites into categories A, B, or C.
Results: This study identified 44 clinical trial sites in 8 Lassa fever-affected countries. Out of these, 35 sites were characterized based on their capacity to hold Lassa fever vaccine clinical trials. A total of 14 sites in 4 countries were identified as ready to host Lassa fever vaccine trials immediately or with little support.
Conclusion: It is feasible to hold Lassa fever vaccine trials in affected countries based on the outcome of the survey. However, the findings are to be validated through sites' visits. This experience with a standardized and objective method of the site assessment is encouraging, and the site selection method used can serve as an orientation to sponsors and researchers planning clinical trials in the region.
Background: Virtual reality (VR) is increasingly used as simulation technology in emergency medicine education and training, in particular for training nontechnical skills. Experimental studies comparing teaching and learning in VR with traditional training media often demonstrate the equivalence or even superiority regarding particular variables of learning or training effectiveness.
Objective: In the EPICSAVE (Enhanced Paramedic Vocational Training with Serious Games and Virtual Environments) project, a highly immersive room-scaled multi-user 3-dimensional VR simulation environment was developed. In this feasibility study, we wanted to gain initial insights into the training effectiveness and media use factors influencing learning and training in VR.
Methods: The virtual emergency scenario was anaphylaxis grade III with shock, swelling of the upper and lower respiratory tract, as well as skin symptoms in a 5-year-old girl (virtual patient) visiting an indoor family amusement park with her grandfather (virtual agent). A cross-sectional, one-group pretest and posttest design was used to evaluate the training effectiveness and quality of the training execution. The sample included 18 active emergency physicians.
Results: The 18 participants rated the VR simulation training positive in terms of training effectiveness and quality of the training execution. A strong, significant correlation (r=.53, P=.01) between experiencing presence and assessing training effectiveness was observed. Perceived limitations in usability and a relatively high extraneous cognitive load reduced this positive effect.
Conclusions: The training within the virtual simulation environment was rated as an effective educational approach. Specific media use factors appear to modulate training effectiveness (ie, improvement through “experience of presence” or reduction through perceived limitations in usability). These factors should be specific targets in the further development of this VR simulation training.
The antimicrobial activity of a phagemixture and a lactic acid bacteriumagainst Staphylococcus aureus isolates from bovine origin was investigated in vitro with regard to possible applications in the therapy of udder inflammation (mastitis) caused by bacterial infections. The S. aureus isolates used for inoculation derived from quarter foremilk samples of mastitis cases. For the examination of the antimicrobial activity, the reduction of the S. aureus germ density was determined [log10 cfu/mL]. The phage mixture consisted of the three obligatory lytic and S. aureus-specific phages STA1.ST29, EB1.ST11 and EB1.ST27 (1:1:1). The selected Lactobacillus plantarum strain with proven antimicrobial properties and the phage mixture were tested against S. aureus in milk, both alone and in combination. The application of the lactic acid bacterium showed only a low reduction ability for a 24 h incubation period. The bacteriophage mixture as well as its combination with the lactic acid bacterium showed high antimicrobial activity against S. aureus for a 24 h incubation period at 37 C, with only the phage mixture showing significance.

Untersuchungen zu Berufen der Wirtschaftsinformatik bleiben weiterhin
interessant, wenn sie helfen können, dem mittlerweile länger anhaltenden
IT-Fachkräftemangel entgegenzuwirken. Eine Untersuchung der Hochschule
Hannover zu Wirtschaftsinformatikern/-informatikerinnen in den ersten zehn Jahren im Beruf zeigt deren berufliche Ziele und die berufliche Zufriedenheit, die sie erlangen. Deutlich wird, dass Frauen und Männer das Arbeitsklima und die Arbeitsbedingungen sehr unterschiedlich wahrnehmen und daher auch unterschiedlich zufrieden sind. Dabei bemängeln Frauen vor allem Merkmale, die mit „fehlender Fairness“ zu beschreiben sind.
Die Nutzung von Messenger-Diensten hat die Nutzung von sozialen Medien übertroffen. Diese Mediennutzung bringt veränderte Erwartungen an Unternehmen mit sich. Unternehmen begegnen den Erwartungen ihrer Kund*innen in der Online-Kundenkommunikation mit dem Einsatz textbasierter Dialogsysteme. Im Facebook-Messenger wurden 2018 bereits über 300.000 Chatbots angeboten. Das Problem ist, dass Studien seit mehreren Jahren aufzeigen, dass diese Kommunikationstechnologie sich bei den Kund*innen noch nicht durchgesetzt hat und häufig noch skeptisch betrachtet wird. Für Unternehmen ist es daher notwendig zu verstehen, welche Kriterien erfüllt sein müssen, um die Akzeptanzbildung der Kund*innen gegenüber textbasierten Dialogsystemen positiv zu beeinflussen.
Das Ziel dieser Arbeit ist es zu betrachten, inwiefern die Eigenschaften textbasierter Dialogsysteme die Akzeptanzkriterien der Kund*innen erfüllen können. Dazu wird die folgende Forschungsfrage gestellt: Wie akzeptieren Kunden den Einsatz textbasierter Dialogsysteme in der Online-Kundenkommunikation von Unternehmen?
Um die Forschungsfrage zu beantworten, wird eine Literaturanalyse durchgeführt. Die Literatur wird mit Studienergebnissen verglichen, um Übereinstimmungen und Abweichungen herauszuarbeiten.
Eine Akzeptanzanalyse hat ergeben, dass Kund*innen textbasierte Dialogsysteme vor allem akzeptieren, wenn sie darin einen Nutzen erkennen. Jedoch beeinflussen neben nutzenorientierten Faktoren auch emotionale Faktoren die Akzeptanz.
Auf dieser Grundlage ist es empfehlenswert, positive und negative Einflussfaktoren des Akzeptanzprozesses zu identifizieren und die Gestaltung textbasierter Dialogsysteme an die Kund*innen anzupassen, bevor diese eingesetzt werden.
In order to reduce antimicrobial treatment and prevent environmental mastitis, the aim of the present study was to investigate associations between herd level factors and microbial load on teat ends with environmental mastitis pathogens. Quarterly farm visits of 31 dairy farms over a one-year period were used for statistical analysis. During each farm visit, teat-skin swabs, bedding and air samples were taken and management practices and herd parameters were documented. Total mesophilic bacteria, esculin-positive streptococci and coliform bacteria were examined in the laboratory procedures from teat skin and environmental samples. Esculin-positive streptococci and coliform bacteria on teat ends increased with high temperature–humidity indices (THI) in the barn during the spring and summer. Significantly more coliform bacteria on teat ends were found in herds with an increased percentage of normal or slightly rough teat ends. Cleaning cubicles more frequently, pre-cleaning teats before milking as well as post-dipping them after milking had a decreasing effect of teat-skin load with total mesophilic and coliform bacteria at the herd level. To conclude, teat-skin bacterial load with environmental pathogens is subject to fluctuations and can be influenced by aspects of farm hygiene.
Ausgangslage: Vor dem Hintergrund der vielfältigen Möglichkeiten des Settings Hochschule, die gesundheitlichen Belange von derzeit 719.203 Beschäftigten und 2,9 Millionen Studierenden zu gestalten und auf diese einzuwirken, bauen immer mehr Hochschulen interne Strukturen zur Gestaltung einer gesundheitsförderlichen Lehr-/ Lernumgebung auf. Besonders die Gesundheit von Studierenden ist in den vergangenen Jahren stärker in den Fokus gerückt, sodass Projekte des Studentischen Gesundheitsmanagements, die die Vermittlung von Gesundheitsförderung an alle Studierende als Aufgabe für den zukünftigen beruflichen Wirkungsbereich beabsichtigen, zunehmend vorangetrieben werden. Bislang gibt es jedoch keine empirischen Untersuchungen, die die MultiplikatorInnenrolle von AbsolventInnen in beruflichen Handlungsfeldern bestätigen.
Ziel der Studie: Ziel der Studie war es herauszufinden, ob und zu welchem Anteil die hochschulisch erworbenen Kompetenzen zum BGM bzw. zur BGF in den beruflichen Handlungsfeldern Anwendung finden und ob sich die AbsolventInnen als MultiplikatorInnen eigeninitiativ an der Gestaltung eines gesundheitsförderlichen Settings beteiligen.
Methoden: Im Rahmen einer als Querschnittsstudie angelegten AbsolventInnen-Befragung zum beruflichen Verbleib beteiligten sich n = 125 AbsolventInnen aus Studiengängen für Pflege- und Gesundheitsberufe. Die Auswertung und Diskussion der Ergebnisse fokussierte sich auf den Befragungsteil zum Betrieblichen Gesundheitsmanagement.
Ergebnisse: Die AbsolventInnen setzen insbesondere verhaltens- und verhältnisbezogene Maßnahmen in ihrem Berufsalltag um und fühlen sich durch ihr Studium gut darauf vorbereitet, Aufgaben zur Ausgangsbestimmung, Maßnahmenentwicklung sowie Evaluationen und Wirksamkeitsnachweise in Bereichen des Betrieblichen Gesundheitsmanagements bzw. der Betrieblichen Gesundheitsförderung zu übernehmen. Der Transfer des gesundheitsförderlichen Wissens und Handelns im Sinne der MultiplikatorInnenrolle zeigt jedoch Handlungsbedarf.
Schlussfolgerungen: Es bedarf einer vertiefenden Reflexion und Stärkung des persönlichen Selbstverständnisses und der professionellen Identität der Gesundheits- und Pflegeberufe mit Blick auf die Betriebliche Gesundheitsförderung unter Einbezug der kontextspezifischen Rahmenbedingungen der Hochschulen und des Gesundheitswesens.
One of the main concerns of this publication is to furnish a more rational basis for discussing bioplastics and use fact-based arguments in the public discourse. Furthermore, “Biopolymers – facts and statistics” aims to provide specific, qualified answers easily and quickly for decision-makers in particular from public administration and the industrial sector. Therefore, this publication is made up like a set of rules and standards and largely foregoes textual detail. It offers extensive market-relevant and technical facts presented in graphs and charts, which means that the information is much easier to grasp. The reader can expect comparative market figures for various materials, regions, applications, process routes, agricultural land use, water use or resource consumption, production capacities, geographic distribution, etc.
The control of clinical mastitis on dairy farms is an essential part of animal health management. Knowledge of the causative microorganisms, the cure rates achievable in the field and essential associated factors are crucial for proper control. The objectives of the present study were to characterize clinical mastitis cases in Germany and to analyze factors influencing cure rates and the recurrence rate. Milk samples of every clinical mastitis case occurring on 12 participating farms were examined cytomicrobiologically. Post-treatment quarter samples were taken after 14 and 21 days. Treatments were performed according to existing farm protocols. Of 2883 clinical mastitis cases, the most prevalent pathogens were Streptococcus (S.) uberis (20.2%) and coliforms (11.6%). In 35% of the milk samples, no bacteriological growth was detected. The overall bacteriological cure rate was 73.3%, while the cytological cure rate was 22.3%, the full cure rate 21.4% and the recurrence rate 18.8%. Regarding the pathogen distribution of severe mastitis, coliform bacteria were detected in 30.5% of the cases, whereas S. uberis was detected in 26.5% thereof. The results show that severe mastitis is caused almost as frequently by Gram-positive as by Gram-negative microorganisms. The low cytological cure rates show that the therapy needs to be further developed with regard to calming the inflammation. The obtained data can be very helpful in assessing internal mastitis scenarios and the effect of measures and therapies.
Die folgende Studie befasst sich mit den Auswirkungen der Corona-Pandemie und deren Effekt – ein verminderter CO2-Ausstoß in Deutschland. Für einen übersichtlichen Vergleich wird im weiteren Verlauf in unterschiedlichen Szenarien darauf eingegangen, wie sich der CO2-Ausstoß im Vergleich zu 2020 ohne die Corona-Pandemie in Deutschland verändern könnte. Grundbasis für die Ermittlungen der folgenden Szenarien ist der CO2-Trend ohne die Corona-Pandemie im Jahr 2020, in dem Deutschland das Emissionsziel von -40 % gegenüber 1990 mit einer Reduktion von lediglich 37 % verfehlt hätte. Im zweiten Szenario wird dargestellt, wie sich die aktuelle Corona-Pandemie mit verschiedenen Lockdown-Phasen auf den CO2-Ausstoß auswirkt. Deutlich wird hierbei, dass trotz der aktuellen Maßnahmen eine längere Lockdown-Phase benötigt wird, um das Klimaziel von -40 % langfristig gesichert zu erreichen. In den Szenarien 3 und 4 liegt der Fokus auf möglichen Handlungs- und Verhaltensweisen nach der Pandemie. Das Szenario 3 betrachtet die Folgen von wirtschaftsfördernden Maßnahmen nach dem Lockdown und dem damit einhergehenden CO2-Anstieg. Wie viel CO2 zusätzlich aufgrund von nachhaltigem und klimaorientiertem Verhalten eingespart werden kann, erläutert das Szenario 4 „CO2 Entwicklung unter Berücksichtigung der Corona-Pandemie 2020 und möglicher positiver Umweltentwicklungen aus dem Lockdown“.
Faktoren, wie die wachsende Bevölkerung, sich verändernde Produktionsfaktoren oder Umwelteinflüsse wurden vernachlässigt. Die Studie zeigt, dass die Chancen, die durch die wirtschaftlichen Einschnitte und die Verhaltensänderungen, die durch die Corona-Pandemie bzw. deren Folgen hervorgerufen wurden, einen maßgeblichen Einfluss auf den CO2-Ausstoß der Bundesrepublik Deutschland haben können.
With an increasing complexity and scale, sufficient evaluation of Information Systems (IS) becomes a challenging and difficult task. Simulation modeling has proven as suitable and efficient methodology for evaluating IS and IS artifacts, presupposed it meets certain quality demands. However, existing research on simulation modeling quality solely focuses on quality in terms of accuracy and credibility, disregarding the role of additional quality aspects. Therefore, this paper proposes two design artifacts in order to ensure a holistic quality view on simulation quality. First, associated literature is reviewed in order to extract relevant quality factors in the context of simulation modeling, which can be used to evaluate the overall quality of a simulated solution before, during or after a given project. Secondly, the deduced quality factors are integrated in a quality assessment framework to provide structural guidance on the quality assessment procedure for simulation. In line with a Design Science Research (DSR) approach, we demonstrate the eligibility of both design artifacts by means of prototyping as well as an example case. Moreover, the assessment framework is evaluated and iteratively adjusted with the help of expert feedback.
Die Bachelorarbeit "Content-Strategien im Luxusmodemarketing" befasst sich mit den jeweiligen Besonderheiten von Content-Strategie und Luxusmodemarketing. Diese Ansatzpunkte werden zur Hilfe genommen, um die jeweiligen Disziplinen aufeinander zu beziehen. Dabei spielen bei der Content-Strategie die Faktoren Zielgruppe, Zeitpunkt, Inhalt, Kanäle und Formate eine übergeordnete Rolle, während im Luxusmodemarketing die Symbolkraft der Marke, die Saisonalität der Mode, die Visualität sowie die Akzeptanz seitens des Konsumenten von Bedeutung sind. Mithilfe dieser Kernaspekte, die in dieser Arbeit anhand von Theorien und Modellen untersucht werden, können Bezugspunkte zu den beiden Disziplinen hergestellt werden.
Der Theorieteil erläutert diese Facetten und arbeitet heraus, welche genauen Muster innerhalb der Content-Strategie sowie des Luxusmodemarketings vorliegen. Schließlich beschreibt der Anwendungsteil, wie die relevanten Zielgruppen, die passenden Inhalte, der richtige Zeitpunkt, die erforderlichen Kanäle und die angemessenen Formate auszusehen haben, um eine Content-Strategie erfolgreich im Luxusmodemarketing zu implementieren. Diese Arbeit versucht dies anhand der gewonnenen theoretischen Erkenntnisse sowie entsprechenden Praxisbeispielen näher zu betrachten.

In the original publication of this article, the authors missed that reverse coding was necessary for the item “Do you work separate from your colleagues?” before calculating the scale ‘social relations’. So they corrected the analysis accordingly. The results with the revised scale show that there are no longer any significant differences between nurses and physicians with regard to this scale.
Unter Crowdsensing versteht man Anwendungen, in denen Sensordaten kollaborativ von einer Menge von Freiwilligen erhoben werden. So kann Crowdsensing eingesetzt werden um die Luftqualität an Orten zu messen, an denen keine fest installierten Sensoren verfügbar sind. In Crowdsensing-Systemen müssen die Teilnehmer koordiniert und die Messdaten verarbeitet werden, um relevante Daten zu erhalten. Im Rahmen der Abschlussarbeit wurde ein System konzipiert und prototypisch umgesetzt, das auf einem Raspberry Pi (unter Einsatz geeigneter Sensoren) Sensordaten erhebt und mit der Complex Event Processing Technologie verarbeitet.
This paper presents the implementation of a GMVC-based WAPSS to damp the interarea modes of power systems. The choise for the GMVC to tackle this problem lies on the fact that it can be used to compensate the time delay due to the latency of the transmission system in a more natural way than other controllers. The paper shows that it is possible to improve system’s closed-loop stability since its behavior is the same as if the time delay is not regarded. Simulation results with Kundur’s System prove that a latency of 1 second at a conventional WAPSS might lead system’s power to oscillate for 50 seconds for a short-circuit at the transmission line, whereas the oscillation decreases to only 5 seconds if the GMVC-based WAPSS is implemented.
