Parasites of the freshwater fish trade in Brazil: science metric study

This paper presents a science metric study of parasites of fish farming in Brazil, including a significant review of the literature. The methodology used was based on researching articles in three different databases, carried out ​on May 2012: ISI (Institute for Scientific Information), SciELO (Scientific Electronic Library Online), and Google Academic. The number of articles on fish parasites is mounting (currently over 110), having much increased since 1995. However, the quantity is still low compared with the amount of papers on parasites of fish from natural environments. In Brazil, the farmed fish that have been studied the most are pacu, tilapia and tambaqui. Monogeneans represent the most prevalent group, followed by protozoa and crustaceans. The regions most researched were the southeast and south, making up 84% of the total literature. The main issue addressed in articles was pathology, followed by treatment and record. In conclusion, the treatment of parasitic diseases of farmed fish in Brazil is still incipient, highlighting the importance and usefulness of management practices to prevent the occurrence of health problems.

Suomen satamissa käsiteltävät pakatut vaaralliset aineet ja esimerkkejä niiden vaaraominaisuuksista

Tämä raportti on tehty osana Kymenlaakson ammattikorkeakoulun hallinnoiman NELIn (North European Logistics Institute) esiselvitystä vaarallisten aineiden tunnistamisesta konttiliikenteessä. Tässä Turun yliopiston merenkulkualan koulutus- ja tutkimuskeskuksen Kotkassa toimivan Merenkulun logistiikan tutkimus -yksikön tekemässä selvityk-sessä on tutkittu kansallista satamaliikenteen PortNet-järjestelmää hyödyntäen, mitä pakattuina kuljetettavia vaarallisia aineita ja kuinka suuria määriä Suomen satamissa käsitellään. PortNet-analyysin tulosten pohjalta tutkimuksessa on selvitetty Suomen satamissa eniten käsiteltyjen, pakattuina kuljetettavien vaarallisten aineiden vaaraominaisuuksia sekä ihmisten että ympäristön kannalta. Tutkimuksessa tehdyn PortNet-analyysin perusteella pakattuja vaarallisia aineita käsiteltiin 16:ssa Suomen satamassa vuonna 2012. Käsiteltyjen aineiden kokonaismäärä oli noin 820 000 tonnia, josta viennin osuus oli 53 % ja tuonnin 47 %. Eniten kuljetettuja IMDG-luokkia olivat luokan 3 palavat nesteet (31 %:n osuus), luokan 9 muut vaaralliset aineet ja esineet (25 %) sekä luokan 8 syövyttävät aineet (23 %). Muiden luokkien osuus oli alle 10 %. Suomen satamissa käsiteltiin vuonna 2012 yhteensä noin 1 020 eri-laista, pakattua vaarallista ainetta. Yli 10 000 tonnia käsiteltyjä aineita oli yhteensä 16, 1 000–10 000 tonnia käsiteltyjä aineita 84, 100–1 000 tonnia käsiteltyjä aineita 148 ja alle 100 tonnia käsiteltyjä aineita noin 770. Eniten käsiteltyjä aineita olivat pääasiassa erilaiset aineyhdisteet ja tarkemmin määrittelemättömät aineet, kuten ympäristölle vaarallinen aine n.o.s, maalit, polymeeripelletit, hartsiliuos, kohotetussa lämpötilassa oleva neste n.o.s. ja nikkelimetallihybridiakut. Näitä kaikkia käsiteltiin Suomen satamissa yli 20 000 tonnia vuonna 2012. Varsinaisista yksittäisistä vaarallisista aineista eniten käsiteltyjä olivat muurahaishappo, vetyperoksidin vesiliuos, natriumkloraatti, ammoniumnitraatti, fenoli ja kloorietikkahappoliuos. Näitä kaikkia käsiteltiin yli 10 000 tonnia vuonna 2012. PortNet-analyysin tulosten pohjalta valittiin kymmenen ainetta, joiden vaaraominaisuuksia sekä ihmisten että ympäristön kannalta tarkasteltiin tarkemmin. Tarkasteluun valittiin, tieteellistä harkintaa käyttäen, eniten kuljetettavia vaarallisia yksittäisiä kemikaaleja. Tarkasteluun valitut kemikaalit olivat muurahaishappo, vetyperoksidi, natrium-kloraatti, kloorietikkahappo, fenoli, akryyliamidiliuos, ksyleenit, akryylinitriili, tolueeni ja epikloorihydriini. Tutkituista kemikaaleista ympäristölle haitallisimpia ovat fenoli, kloorietikkahappo ja akryyliamidiliuos. Ihmisen kannalta kaikki 10 tutkittua kemikaalia muodostavat onnettomuustilanteessa riskin ihmisten terveydelle joko syövyttävyytensä, reaktiivisuutensa tai myrkyllisyytensä vuoksi. Osa kemikaaleista voi aiheuttaa ihmisille myös kroonisia haittoja, kuten kohonnutta syöpäriskiä tai muutoksia perimässä, joko suurina kerta-annoksina tai pieninä toistuvina pitoisuuksina. Suomen satamissa käsiteltävien pakattujen kemikaalien erilaisuus ja suuri lukumäärä tekevät niistä vaikeasti hallittavissa olevan riskitekijän. Yleisesti ottaen voidaan sanoa, että pakatuista kemikaaleista aiheutuu pienehköissä vuototilanteissa suurempi uhka ihmisen terveydelle kuin ympäristölle, kun taas irtolastikuljetuksissa tapahtuvien onnettomuuksien yhteydessä vuotaneen aineen määrä on yleensä suurempi ja näin ollen myös ympäristölle koituva uhka voi olla suuri.

Scientific creativity and diversity of physical work environment: framework development

The aim of this research was to develop a framework to analyze how physical environment influences scientific creativity. Due to the relative novelty of this topic, there is still a gap in the unified method to study connection between physical environment and creativity. Therefore, in order to study this issue deeply, the qualitative method was used (interviews and qualitative questionnaire). Scientists (PhD students and senior researchers) of Graduate School of Management were interviewed to build the model and one expert interview was conducted to assess its validity. The model highlights several dimensions via which physical environment can influence scientific creativity: Comfort, Instruments and Diversity. Comfort and Instruments are considered to be related mostly to productivity, an initial requirement for creativity, while Diversity is the factor responsible for supporting all the stages of scientific creative process. Thus, creative physical environment is not one place by its nature, but an aggregative phenomenon. Due to two levels of analysis, the model is named the two-level model of creative physical environment.

Mapping cancer, cardiovascular and malaria research in Brazil

This paper presents performance indicators for the Brazilian cancer, cardiovascular and malaria research areas from 1981 to 1995. The data show an increasing number of papers since 1981 and author numbers indicate a continuous growth of the scientific community and suggest an expected impact of scientific activity on biomedical education. The data also characterize cardiovascular research as a well-established area and cancer research as a faster growing consolidating field. The 1989-1994 share of Brazilian articles among world publications shows a growing trend for the cancer (1.61) and cardiovascular (1.59) areas, and a decrease for the malaria area (0.89). The burden of the three diseases on society is contrasted by the small number of consolidated Brazilian research groups, and a questionable balance of thematic activity, especially with regard to malaria. Brazilian periodicals play an important role in increasing the international visibility of science produced in the country. Cancer and cardiovascular research is strongly concentrated in the Southeastern and in Southern regions of Brazil, especially in São Paulo (at least one address from São Paulo in 64.5% of the 962 cancer articles and in 66.9% of the 2250 cardiovascular articles, the second state being Rio de Janeiro with at least one address in 14.1 and 11% of those articles, respectively). Malaria research (468 articles) is more evenly distributed across the country, following the pattern of the endemic distribution of the disease. Surveying these national indicator trends can be useful to establish policies in the decision process about health sciences, medical education and public health.

Reporting on methods of subgroup analysis in clinical trials: a survey of four scientific journals

Results of subgroup analysis (SA) reported in randomized clinical trials (RCT) cannot be adequately interpreted without information about the methods used in the study design and the data analysis. Our aim was to show how often inaccurate or incomplete reports occur. First, we selected eight methodological aspects of SA on the basis of their importance to a reader in determining the confidence that should be placed in the author's conclusions regarding such analysis. Then, we reviewed the current practice of reporting these methodological aspects of SA in clinical trials in four leading journals, i.e., the New England Journal of Medicine, the Journal of the American Medical Association, the Lancet, and the American Journal of Public Health. Eight consecutive reports from each journal published after July 1, 1998 were included. Of the 32 trials surveyed, 17 (53%) had at least one SA. Overall, the proportion of RCT reporting a particular methodological aspect ranged from 23 to 94%. Information on whether the SA preceded/followed the analysis was reported in only 7 (41%) of the studies. Of the total possible number of items to be reported, NEJM, JAMA, Lancet and AJPH clearly mentioned 59, 67, 58 and 72%, respectively. We conclude that current reporting of SA in RCT is incomplete and inaccurate. The results of such SA may have harmful effects on treatment recommendations if accepted without judicious scrutiny. We recommend that editors improve the reporting of SA in RCT by giving authors a list of the important items to be reported.

The use and misuse of the "impact factor" as a parameter for evaluation of scientific publication quality: a proposal to rationalize its application

We present a critical analysis of the generalized use of the "impact factor". By means of the Kruskal-Wallis test, it was shown that it is not possible to compare distinct disciplines using the impact factor without adjustments. After assigning the median journal the value of one (1.000), the impact factor value for each journal was calculated by the rule of three. The adjusted values were homogeneous, thus permitting comparison among distinct disciplines.

The modest but growing Brazilian presence in psychiatric, psychobiological and mental health research: assessment of the 1998-2002 period

The objective of the present survey was to assess the Brazilian scientific production in psychiatry, psychobiology, and mental health during the 1998-2002 period. The universities' graduate programs concentrate the vast majority of the scientific production in Brazil. We assessed the annual reports from the graduate programs to the Brazilian Ministry of Education concerning master's and doctoral theses and the articles published in journals indexed by the Institute of Scientific Information (ISI). There are nine Master's and Doctoral graduate programs dedicated to research in psychiatry, neuropsychiatry, psychobiology, and mental health in the country, seven being located in southern states. During the 5-year period, from 1998 to 2002, 186 students received their doctorate degree (37/year). The programs published 637 articles in journals indexed by ISI, the majority of them in journals with an impact factor higher than 2. The research advisors' productivity varied among graduate programs, ranging from 0.6 to 2.0 articles per year in ISI-indexed journals. Despite the substantial barriers faced by the Brazilian scientific community (mainly financial and writing difficulties), Brazil's scientific mental health production is on the rise. The number of articles published in ISI-indexed journals has doubled without a significant increase in the number of graduate theses, suggesting that there was an improvement in both the quality of the scientific production and the productivity of the graduate programs. Based on these data, it is reasonable to predict a tendency to an increase in production over the next few years.

Brazilian medical publications: citation patterns for Brazilian-edited and non-Brazilian literature

Today, the quality of a scientific article depends on the periodical in which it is published and on the number of times the article is cited in the literature. In Brazil, the criteria for the evaluation of this scientific production are improving. However, there is still some resistance, with authors arguing that Brazilian publications must be preferentially addressed to the national readers and, therefore, they should ideally be written in Portuguese. In order to determine the kind of scientific journals cited in the reference lists of articles published in medical periodicals edited in Brazil, in the present study we determine the rate of Portuguese/English citations. Three issues of 43 periodicals (19 indexed in SciELO, 10 in PubMed, 10 in LILACS, and 4 in the ISI-Thompson base) of different medical specialties were analyzed, and the number of both Portuguese and English citations in the reference list of each article was recorded. The results showed that in Brazilian-edited journals the mean number of citations/article was 20.9 ± 6.9 and the percentage of citations of international non-Brazilian periodicals was 86.0 ± 11.2%. Of the latter, 94.4 ± 7.0 are indexed by ISI-Thompson. Therefore, we conclude that Brazilian medical scientists cite the international non-Brazilian periodicals more than the national journals, and most of the cited papers are indexed by ISI-Thompson.

Profile of the Brazilian scientific production in multiple sclerosis

This paper analyzes the profile of the Brazilian output in the field of multiple sclerosis from 1981 to 2004. The search was conducted through the MEDLINE and LILACS databases, selecting papers in which the term "multiple sclerosis" was defined as the main topic and "Brazil" or "Brasil" as others. The data were analyzed regarding the themes, the state in Brazil and institution where the papers were produced, the journals where the papers were published, journal's impact factor, and language. The search disclosed 141 documents (91 from MEDLINE and LILACS, and 50 from LILACS only) published in 44 different journals (23 of them MEDLINE-indexed). A total of 111 documents were produced by 17 public universities, 29 by 3 private medical schools and 1 by a non-governmental organization. There were 65 original contributions, 37 case reports, 20 reviews, 6 PhD dissertations, 5 guidelines, 2 validation studies, 2 clinical trials, 2 chapters in textbooks, 1 Master of Science thesis, and 1 patient education handout. The journal impact factor ranged from 0.0217 to 6.039 (median 3.03). Of 91 papers from MEDLINE, 65 were published by Arquivos de Neuro-Psiquiatria. More than 90% of the papers were written in Portuguese. São Paulo was the most productive state in the country, followed by Rio de Janeiro, Minas Gerais and Paraná. Eighty-two percent of the Brazilian output came from the Southeastern region.
