Strengthening the health surveillance of marine mammals in the waters of metropolitan France by monitoring strandings

peer reviewedMonitoring the health status of marine mammals is a priority theme that France aims to develop with the other European Union Member States in the next two years, in the context of the Marine Strategy Framework Directive. With approximately 5,000 km of coastline and for nearly ten years, France has been recording an average of 2,000 strandings per year, which are monitored by the National Stranding Network, managed by Pelagis, the observatory for the conservation of marine mammals from La Rochelle University and the French National Center for Scientific Research. Since 1972, this network has successively evolved from spatial and temporal faunistic description to, nowadays, the detection of major causes of mortality. It now aims to carry out epidemiological studies on a population scale. Thus, a strategy to strengthen the monitoring of marine mammals’ health status based on stranding data has been developed. This strategy will allow for a more accurate detection of anthropogenic cause of death as well as those of natural origin. It will allow the monitoring of time trends and geographical differences of diseases associated with conservation and public health issues while ensuring the early detection of emerging and/or zoonotic diseases of importance. It will also allow a better assessment of the consequences of human activities on these animal populations and on the environment. Thus, this strategy is fully in line with the “One Health” approach which implies an integrated vision of public, animal and environmental health. It is broken down into four surveillance modalities: (1) general event-based surveillance (GES); (2) programmed surveillance (PS); (3) specific event-based surveillance (SES); (4) and in the longer term, syndromic surveillance (SyS). This article describes the French strategy as well as these different surveillance modalities, the levels of examinations and the associated sampling protocols and finally, the method of standardisation of the data collected. The objective is to present the strategy developed at the French level in order to integrate it into a future strategy shared at the European level to standardise practices and especially complementary analysis, necessary for a better evaluation of the health status of these mobile marine species

Entrepreneurship and Creative Professions – A Micro-Level Analysis

It has widely been recognized that creativity plays an immense role not only for arts, sciences, and technology, but also for entrepreneurship, innovation, and thus, economic growth. We analyze the level and the determinants of self-employment in creative professions at the level of individuals. The analysis is based on the representative micro data of the German Socio-Economic Panel (SOEP). The findings suggest that people in creative professions appear more likely to be self-employed and that a high regional share of people in the creative class increases an individual's likelihood of being an entrepreneur. Investigating the determinants of entrepreneurship within the creative class as compared to non-creative professions reveals only some few differences

The use of urea for the treatment of onychomycosis: a systematic review

Abstract Background Onychomycosis, a fungal infection affecting the nail plate, is a common condition often requiring prolonged treatment regimens, with low success rates. Urea is one treatment option, which is thought to improve the efficacy of topical and oral antifungal agents. Despite a theoretical basis for the use of urea for the treatment of onychomycosis, the evidence-base for this treatment has not been systematically reviewed. Aim The purpose of this study was to conduct a systematic literature review to determine the efficacy and safety of urea as a monotherapy and as adjunct therapy, compared to other treatment regimens for onychomycosis. Method A systematic literature search of ten electronic databases was conducted. Only studies that used microscopy and culture or other validated laboratory-based testing method to confirm the presence of a fungal infection before treatment were included. The outcome measures assessed were efficacy (defined in terms of mycological, clinical and complete cure) and safety (defined as self-reported adverse events). Results The systematic search yielded 560 unique studies for review. Of these, only six were eligible for inclusion. All studies were observed to have methodological concerns, most studies consisted of small sample sizes and were difficult to compare given heterogeneity in outcome measures and follow-up time. Despite this, a trend was observed to suggest that urea, when added to topical or oral antifungal treatment regimens, improved efficacy of the treatment. Conclusion This review suggests that topical urea, as an adjunct to topical and oral antifungal treatment regimens, may improve the efficacy of treatment. However, further research is needed

Consensus-based statements for assessing clinical competency in podiatry-related work integrated learning

Abstract Background The training of undergraduate and graduate-entry podiatry students in Australia and New Zealand includes practical sessions in a simulated and real-life clinical setting and Work Integrated Learning (WIL) comprising professional clinical placements. Student performance during WIL is evaluated by their Clinical Educators using clinical competency tools. Having a standardised and validated clinical assessment tool for WIL in podiatry would facilitate consistency in assessment, promote standardisation between programs, and ensure that all podiatry students are assessed against a set of criteria over the course of their clinical programs to the point of threshold clinical competency. Therefore, the aim of this study was to develop a series of consensus-based statements via Delphi technique as the first step towards developing guidelines to direct the assessment of podiatry students during WIL. Methods This study used a three-round modified Delphi consensus method. A panel of 25 stakeholders was sought. Specifically, representation from each of the universities in Australia and New Zealand who provide entry level programs, Clinical Educators, podiatry student representatives, new podiatry graduates and consumers (podiatrists hiring new graduates). The survey for Round 1 aimed for consensus and consisted of five open-ended questions. Questions one to three asked respondents to nominate what they considered were the important elements that needed to be assessed for podiatry students undertaking WIL for: Clinical performance/skills, Communication and Professional behaviour, Question 4 asked respondents to identify further/other elements of importance, whilst Question 5 asked a) how these elements should be evaluated and b) how should overall competency and ability to progress within the program be determined. Round 2 and 3 aimed to gather agreement and the questions were based on the responses from previous rounds. Results Twenty-five participants agreed to participate, 17 females (68%) and eight males (32%). The panel consisted of 10 podiatry educators (40%), nine Clinical Educators (36%), two student representatives (8%), two new podiatry graduates (8%) and two consumers (8%). From the 25 recruited participants, 21 responded to Round one, 18 to Round two and 17 in Round three. At the conclusion of the Delphi survey, 55 statements had reached consensus or agreement. Conclusions This Delphi study is the first of its kind for the podiatry profession to develop consensus-based statements regarding the assessment of WIL. Fifty-five statements pertinent to the assessment of WIL were identified. This is an important first step toward the development of a consistent WIL assessment tool which may be applied across entry-level podiatry programs across Australia and New Zealand

Quantitative comparison of catalytic mechanisms and overall reactions in convergently evolved enzymes : implications for classification of enzyme function

The authors thank the National Institutes of Health (NIH R01 GM60595 to PCB) and the Scottish Universities Life Sciences Alliance (SULSA to JBOM) for funding.Functionally analogous enzymes are those that catalyze similar reactions on similar substrates but do not share common ancestry, providing a window on the different structural strategies nature has used to evolve required catalysts. Identification and use of this information to improve reaction classification and computational annotation of enzymes newly discovered in the genome projects would benefit from systematic determination of reaction similarities. Here, we quantified similarity in bond changes for overall reactions and catalytic mechanisms for 95 pairs of functionally analogous enzymes (non-homologous enzymes with identical first three numbers of their EC codes) from the MACiE database. Similarity of overall reactions was computed by comparing the sets of bond changes in the transformations from substrates to products. For similarity of mechanisms, sets of bond changes occurring in each mechanistic step were compared; these similarities were then used to guide global and local alignments of mechanistic steps. Using this metric, only 44% of pairs of functionally analogous enzymes in the dataset had significantly similar overall reactions. For these enzymes, convergence to the same mechanism occurred in 33% of cases, with most pairs having at least one identical mechanistic step. Using our metric, overall reaction similarity serves as an upper bound for mechanistic similarity in functional analogs. For example, the four carbon-oxygen lyases acting on phosphates (EC 4.2.3) show neither significant overall reaction similarity nor significant mechanistic similarity. By contrast, the three carboxylic-ester hydrolases (EC 3.1.1) catalyze overall reactions with identical bond changes and have converged to almost identical mechanisms. The large proportion of enzyme pairs that do not show significant overall reaction similarity (56%) suggests that at least for the functionally analogous enzymes studied here, more stringent criteria could be used to refine definitions of EC sub-subclasses for improved discrimination in their classification of enzyme reactions. The results also indicate that mechanistic convergence of reaction steps is widespread, suggesting that quantitative measurement of mechanistic similarity can inform approaches for functional annotation.Publisher PDFPeer reviewe
