Background
Uncomplicated urinary tract infections (UTI) are common in general practice and usually treated with antibiotics. This contributes to increasing resistance rates of uropathogenic bacteria. A previous trial showed a reduction of antibiotic use in women with UTI by initial symptomatic treatment with ibuprofen. However, this treatment strategy is not suitable for all women equally. Arctostaphylos uva-ursi (UU, bearberry extract arbutin) is a potential alternative treatment. This study aims at investigating whether an initial treatment with UU in women with UTI can reduce antibiotic use without significantly increasing the symptom burden or rate of complications.
Methods
This is a double-blind, randomized, and controlled comparative effectiveness trial. Women between 18 and 75 years with suspected UTI and at least two of the symptoms dysuria, urgency, frequency or lower abdominal pain will be assessed for eligibility in general practice and enrolled into the trial. Participants will receive either a defined daily dose of 3 × 2 arbutin 105 mg for 5 days (intervention) or fosfomycin 3 g once (control). Antibiotic therapy will be provided in the intervention group only if needed, i.e. for women with worsening or persistent symptoms. Two co-primary outcomes are the number of all antibiotic courses regardless of the medical indication from day 0–28, and the symptom burden, defined as a weighted sum of the daily total symptom scores from day 0–7. The trial result is considered positive if superiority of initial treatment with UU is demonstrated with reference to the co-primary outcome number of antibiotic courses and non-inferiority of initial treatment with UU with reference to the co-primary outcome symptom burden.
Discussion
The trial’s aim is to investigate whether initial treatment with UU is a safe and effective alternative treatment strategy in women with UTI. In that case, the results might change the existing treatment strategy in general practice by promoting delayed prescription of antibiotics and a reduction of antibiotic use in primary care.
Leo A. Nefiodow, einer der angesehensten Vordenker der Informationsgesellschaft, verweist auf die großen Schäden und Verluste, die uns momentan durch psychische Störungen wie beispielsweise Angst, Depressionen, Burnout und ihre Folgen wie Gewalt, Kriminalität, Drogenmissbrauch und Erkrankungen entstehen. Die Förderung psychosozialer Gesundheit wäre somit geeignet, sowohl das Wohlbefinden des einzelnen Menschen zu verbessern als auch der Wirtschaft und der gesamten Gesellschaft einen Entwicklungsschub zu verleihen. Im Rahmen des Arbeitspapiers geht es darum, Möglichkeiten des Gegensteuerns aus dem Blickwinkel von Achtsamkeit vorzustellen. U. a. am praktischen Beispiel einer Schule wird versucht, das Wirkprinzip von Achtsamkeit zur Förderung psychosozialer Gesundheit in einer sozialen Einheit zu verdeutlichen.
Organisation der IT-Sicherheit in der Produktion : in zehn Schritten zur sicheren Produktionsanlage
(2018)
Der folgende Beitrag befasst sich mit der IT-Sicherheit von Produktionsanlagen aus Betreibersicht. Hierbei liegt der Fokus auf den organisatorischen Aspekten der IT-Sicherheit. In einer Bestandsaufnahme werden zunächst die Probleme herausgearbeitet, die entstehen, sofern sich eine Organisation im Wesentlichen auf technische Aspekte der IT-Sicherheit konzentriert. Daraus wird die Notwendigkeit organisatorischer Maßnahmen abgeleitet. Eine Betrachtung von Normen und Standards, die sich mit den organisatorischen Aspekten der IT-Sicherheit in der Produktion befassen, liefert das Grundgerüst für die Ableitung eines Maßnahmenplans. Der daraus resultierende 10-Punkte-Plan zur Umsetzung der IT-Sicherheit in der Produktion schließt den Beitrag ab.
Background: Oral cancer is among the top three types of cancers in India. Severe alcoholism, use of tobacco in the form of cigarettes, smokeless tobacco, and betel nut chewing are the most common risk factors for oral cancer. Often individuals with pre cancer even notice the alterations, such as reduced mouth opening in oral submucous fibrosis (OSMF), but they are not aware about the causes and consequences of these changes. Awareness about causes and features of oral cancers can be very helpful in prevention, control and early diagnosis of oral cancer.
Methods: A cross-sectional study was carried out among students from Mumbai University, India during May-June 2017. Five hundred students were approached to participate in the study of which 400 agreed to participate. Pretested questionnaire was distributed and collected data was analyzed using IBM SPSS version 23.
Results: There were 199 (49%) males and 201 (50%) females in the study and response rate was (80%). Respondents had good knowledge about oral cancer. Seventy four percent (268/362) respondents correctly identified smoking, and tobacco chewing as possible causes of oral cancer. Almost all (96%; 348/362) respondents correctly responded that oral cancer does not spread from person to person through touch or speaking. Seventy two percent (260/362) respondents believed that oral cancer is curable. Significantly higher number of male (98%) compared to female participants answered correctly to questions regarding spread of disease and occurrence of oral cancer in AIDS patients.
Conclusions: Participants showed good knowledge about oral cancer. Female participants showed lesser knowledge compared to male counterparts. Details about oral cancer should be incorporated in the undergraduate curriculum and periodic awareness programs should be organized for students.
The growing importance of renewable generation connected to distribution grids requires an increased coordination between transmission system operators (TSOs) and distribution system operators (DSOs) for reactive power management. This work proposes a practical and effective interaction method based on sequential optimizations to evaluate the reactive flexibility potential of distribution networks and to dispatch them along with traditional synchronous generators, keeping to a minimum the information exchange. A modular optimal power flow (OPF) tool featuring multi-objective optimization is developed for this purpose. The proposed method is evaluated for a model of a real German 110 kV grid with 1.6 GW of installed wind power capacity and a reduced order model of the surrounding transmission system. Simulations show the benefit of involving wind farms in reactive power support reducing losses both at distribution and transmission level. Different types of setpoints are investigated, showing the feasibility for the DSO to fulfill also individual voltage and reactive power targets over multiple connection points. Finally, some suggestions are presented to achieve a fair coordination, combining both TSO and DSO requirements.
Portable-micro-Combined-Heat-and-Power-units are a gateway technology bridging conventional vehicles and Battery Electric Vehicles (BEV). Being a new technology, new software has to be created that can be easily adapted to changing requirements. We propose and evaluate three different architectures based on three architectural paradigms. Using a scenario-based evaluation, we conclude that a Service-Oriented Architecture (SOA) using microservices provides a higher quality solution than a layered or Event-Driven Complex-Event-Processing (ED-CEP) approach. Future work will include implementation and simulation-driven evaluation.
A nonblinded, positively controlled, noninferiority trial was conducted to evaluate the efficacy of an alternative, nonantibiotic therapy with Masti Veyxym® to reduce ineffective antibiotic usage in the treatment of nonsevere clinical mastitis (CM) in cows with longer lasting udder diseases. The solely intramammary treatment with Masti Veyxym® (three applications, 12 hr apart) and the combined treatment with Masti Veyxym® and antibiotics as usual on the farm according to label of the respective product were compared with the reference treatment of solely antibiotic therapy. The matched field study was conducted on eight free-stall dairy farms located in Eastern Germany. Cases of mild-to-moderate CM in cows with longer lasting high somatic cell counts in preceding dairy herd improvement test days and with previous CM cases in current lactation were randomly allocated to one of the three treatment groups. A foremilk sample of the affected quarter was taken before treatment and again approximately 14 days and 21 days after the end of therapy for cyto-bacteriological examination. Primary outcomes were clinical cure (CC) and no CM recurrence within 60 days after the end of treatment (no R60). Bacteriological cure (BC) and quarter somatic cell count (QSCC) cure were chosen as secondary outcomes although low probabilities of BC and QSCC cure for selected cows were expected. The study resulted in the following findings: the pathogens mostly cultured from pretreatment samples were Streptococcus uberis, followed by Staphylococcus aureus and coagulase-negative staphylococci. There were no significant differences between the two test treatments in comparison with the reference treatment regarding all outcome variables. The sole therapy with Masti Veyxym® resulted in a numerically lower likelihood of BC without significant differences to the reference treatment. The combined therapy group showed a numerically higher nonrecurrence rate than the two other treatment groups and noninferiority compared to the reference treatment was proven. Having regard to the selection criteria of cows in this study, the findings indicated that sole treatment with Masti Veyxym® in nonsevere CM cases may constitute an alternative therapy to reduce antibiotics. However, noninferiority evaluations were mostly inconclusive. Further investigations with a larger sample size are required to confirm the results and to make a clear statement on noninferiority.

Im Social Web wird der Gatekeeper zum Gatewatcher. Unternehmen können medial eigene Inhalte an die relevanten Bezugsgruppen vermitteln, ohne auf einen Gatekeeper angewiesen zu sein. Die Relevanz der Inhalte wird allerdings durch das Publikum bestimmt. Die Nachrichtenwerttheorie, die ursprünglich auf die Selektion von Journalisten von Nachrichten geprägt war, muss uminterpretiert werden, um aktuell zu bleiben. Welche Nachrichtenfaktoren bestimmen also die Interaktion des Publikums und sorgen für wahre Relevanz in den Sozialen Medien?
Informationskompetenz ist eine Schlüsselkompetenz für gesellschaftliche Teilhabe. Unter dem Eindruck des „Framework for Information Literacy for Higher Education“ der ACRL verändert sich das Verständnis von Informationskompetenz. Die Angebote zur Förderung von Informationskompetenz von Universitäts- und Hochschulbibliotheken müssen besser in die Lehre in den Disziplinen integriert werden. E-Learning-Formate eigenen sich hierfür besonders gut. Für die gelungene Gestaltung von E-Learning-Angeboten sind Kenntnisse über Lerntheorien und Mediendidaktik notwendig. Auf eine breite theoretische Betrachtung folgt der Entwurf mediendidaktischer Konzepte für ein E-Learning-Angebot zur Förderung von Informationskompetenz an der Universitätsbibliothek der Freien Universität Berlin.
Marketing, get ready to rumble — How rivalry promotes distinctiveness for brands and consumers
(2018)
Scholars typically advise brands to stay away from public conflict with competitors as research has focused on negative consequences - e.g., price wars, escalating hostilities, and derogation. This research distinguishes between rivalry between firms (inter-firm brand rivalry) and rivalry between consumers (inter-consumer brand rivalry). Four studies and six samples show both types of rivalry can have positive consequences for both firms and consumers. Inter-firm brand rivalry boosts perceived distinctiveness of competing brands independent of consumption, attitude, familiarity, and involvement. Inter-consumer brand rivalry increases consumer group distinctiveness, an effect mediated by brand identification and rival brand disidentification. We extend social identity theory by demonstrating that: 1) outside actors like firms can promote inter-consumer rivalry through inter-firm rivalry and 2) promoting such conflict can actually provide benefits to consumers as well as firms. The paper challenges the axiom “never knock the competition,” deriving a counter-intuitive way to accomplish one of marketing's premier objectives.
The effect of magnetism on hydrogen adsorption and subsurface diffusion through face-centred cubic (fcc) γ-Fe(0 0 1) was investigated using spin-polarised density functional theory (s-DFT). The non-magnetic (NM), ferromagnetic (FM), and antiferromagnetic single (AFM1) and double layer (AFMD) structures were considered. For each magnetic state, the hydrogen preferentially adsorbs at the fourfold site, with adsorption energies of 4.07, 4.12, 4.03 and 4.05 eV/H atom for the NM, FM, AFM1 and AFMD structures. A total barrier of 1.34, 0.90, 1.32 and 1.25 eV and a bulk-like diffusion barrier of 0.6, 0.2, 0.4 and 0.3 eV were calculated for the NM, FM, AFM1 and AFMD magnetic states. The Fe atoms nearest to the H atom exhibited a reduced magnetic moment, whereas the next-nearest neighbour Fe atoms exhibited a non-negligible local perturbation in the magnetic moment. The presence of magnetically ordered structures has a minimal influence on the minimum energy path for H diffusion through the lattice and on the adsorption of H atoms on the Fe(0 0 1) surface, but we computed a significant reduction of the bulk-like diffusion barriers with respect to the non-magnetic state of fcc γ-Fe.

Against the background of climate change and finite fossil resources, bio-based plastics have been in the focus of research for the last decade and were identified as a promising alternative to fossil-based plastics. Now, with an evolving bio-based plastic market and application range, the environmental advantages of bio-based plastic have come to the fore and identified as crucial by different stakeholders. While the majority of assessments for bio-based plastics are carried out based on attributional life cycle assessment, there have been only few consequential studies done in this area. Also, the application of eco-design strategies has not been in the focus for the bio-based products due to the prevailing misconceptions of renewable materials (as feedstock for bio-based plastics) considered in itself as an ‘eco-design strategy’. In this paper, we discuss the life cycle assessment as well as eco-design strategies of a bio-based product taking attributional as well as consequential approaches into account.

Background: Discovery of antibiotics have helped to manage the devastating diseases. Presently, the antibiotic era is threatened by the emergence of high level of antibiotic resistance of important pathogens. Misuse of antibiotics poses a serious risk to infectious disease control. It is necessary to improve public awareness to bring a change in the behavior of consumers. Therefore, present study was undertaken to assess the existing knowledge, attitude and practices related to antibiotic usage among university students.
Methods: A cross-sectional study was carried out among students from Mumbai University, India during May-June 2017. 300 students were approached to participate in the study of which 250 agreed to participate (males: 117; females: 133). Pretested questionnaire was distributed and collected data was analyzed using IBM SPSS version 23.
Results: Substantial number (33% and 40%) participants were unaware about the differences in antibiotic-anti-inflammatory drugs and antibiotic-antipyretics respectively. 28% of the participants thought it is right to stop antibiotics only based on symptoms improvement. Sixty eight percent and seventy nine percent participants believed that antibiotics should always be prescribed to treat flu like symptoms and pneumonia respectively.
Conclusions: Participants demonstrated poor knowledge about antibiotics. Similarly, their attitude and practice toward antibiotic use was associated with misconceptions. An educational intervention can be introduced to make them aware about rational antibiotic practices.
Background: Human papillomavirus (HPV) is a common sexually transmitted infection (STI) that may cause cervical cancer and other malignancies including those of the vulva, anus, vagina, penis, head and neck. In most Asian countries including India, cervical cancer is the second most common cancer in women. Awareness about HPV and cervical cancer, use of vaccines can be very helpful in prevention, control and early diagnosis of cervical cancer. Methods: A cross-sectional study was carried out among students from Mumbai University, India during May - June 2017. Two hundred students were approached to participate in the study of which 142 were selected to participate (males: 54; females: 88). Pretested questionnaire was distributed and collected data was analyzed using IBM SPSS version 23. Results: Participants had fair knowledge (61% average) about HPV, whereas knowledge about symptoms, prevention and spread of HPV was very poor i.e. 18%. Knowledge about HPV vaccine was 50% and 78% participants had positive attitude for HPV vaccine. Conclusions: This study showed the lacunas in the pharmacy curriculum and urgent need to create awareness of HPV among bachelor of pharmacy students from Mumbai University.
Knowledge and attitude towards voluntary blood donation among students from Mumbai University
(2018)
Background: Blood is scarce; its demand far outweighs the supply. In addition to limited supply, the issue of safety especially with regard to the risk of transfusion transmissible infection is also an issue of utmost concern especially in the developing countries. Blood transfusion services in India have gained special significance in recent years and forms a vital part of national health care system. Voluntary Non-Remunerated Blood Donation (VNRBD) is the safest of all types of blood donations. One of the potential sources that can be tapped for blood donation is the young and physically fit students from educational institutions across India. Methods: A cross-sectional study was carried out among students from Mumbai University, India during May–June 2017. Two hundred and fifty students were approached to participate in the study of which 201 agreed to participate (males: 104; females: 97). Pretested questionnaire was distributed and collected data was analyzed using IBM SPSS version 23. Results: High number of participants agreed about encouraging general public about voluntary blood donation (96%; 193/201), lack of awareness about VBD in general public (82%; 164/201). But not a single participant was able to respond to the knowledge part of the questionnaire with 100% accuracy. Almost all the participants had correct knowledge about blood groups (98%; 196/201) and blood matching need (195/201; 97%). Conclusions: Participants showed good attitude but demonstrated poor knowledge about voluntary blood donation. Details about blood donation should be incorporated in the undergraduate curriculum and periodic awareness programs should be organized for students.
Background: Epilepsy is a chronic disorder of the brain that affects people worldwide. The overall prevalence (3.0-11.9 / 1,000) and incidence (0.2-0.6/1,000) of epilepsy in India are comparable to the rates of high-income countries. The high prevalence of negative attitudes towards epilepsy has been highlighted by several studies. Pharmacy students represent a better-educated section of society regarding drugs and have the potential to create awareness, and influence attitudes towards the disease. Thus, it is important that they have the appropriate and updated knowledge and appropriate attitude towards epilepsy and antiepileptic drugs. Objective of the present study was to determine the Mumbai University pharmacy student’s awareness about epilepsy, so as to know the kind of education and awareness strategies that would be applicable to them.
Methods: A cross-sectional study was carried out among students from Mumbai University, India during May-June 2017. Two hundred and fifty students were approached to participate in the study of which 213 agreed to participate (males: 107; females: 106). Pretested questionnaire was distributed and collected data was analyzed using IBM SPSS version 23.
Results: Response rate for this study was 85.2% (213/250). Ninety six percent (204/213) of the participants had heard or read about epilepsy. Overall knowledge was poor (40.2%) and attitude was fair (75.3%). None of the participants were aware about recent research regarding hereditary nature of epilepsy. Only 2 (0.98%) students were aware how to perform the first aid in epilepsy. Only 6.8% participants felt that epileptics should participate in sports.
Conclusions: The findings of this study show that, even with extensive curriculum covering diseases, drugs and relevant laws of land, the knowledge and attitude scores were low. There is a need to have focused education and campaigns to increase the knowledge and attitude towards epilepsy.
