This paper presents records extending or confirming the distribution of Mediterranean species. Three alien algae are included, namely Codium taylorii reported for the first time from the Aegean and Turkey (Izmir Gulf), Caulerpa racemosa var. cylindracea (Karpathos and Chalki Isl., Aegean Sea) and Ganonema farinosum (Karpathos Isl., Aegean Sea). As far as animals are concerned, Litarachna divergens (Acari: Hydrachnidia) was recorded (Side, Eastern Mediterranean) and represents a new amendment at genus level for Turkish fauna. Other invertebrates include alien species such as the crabs Dyspanopeus sayi (Lago Fusaro, SW Italy), Percnon gibbesi (Larnaca, Cyprus; Karpathos and Chalki Isl., Aegean Sea) and Callinectes sapidus (Voda estuary, NW Greece), the nudibranch Aplysia dactylomela (Boka Kotorska Bay, Montenegro), the gastropod Conomurex persicus (Karpathos and ChalkiIsl., Aegean Sea) and the bryozoan Electra tenella (Livorno harbour and Messina Straits area). The alien fish Siganus luridus, Siganus rivulatus, Fistularia commersonii, Sphyraena chrysotaenia and Sargocentron rubrum are also reported from the islands of Karpathos and Chalki, and Pteragogus pelycus from Heraklion Bay, Crete. In addition, new localities for four rare Mediterranean inhabitants are given: the cephalopod Thysanoteuthis rhombus (NW Sardinia) and the fish: Lampris guttatus (Calabria, S Italy), Petromyzon marinus (Gokova Bay) and Remora australis (Saronikos Gulf), while the opisthobranch gastropod Cerberilla bernadettae is reported for the first time from the E Mediterranean (Cyprus). Finally, three species of the Aegean ascidiofauna are recorded for the first time: Lissoclinum perforatum, Ciona roulei and Ecteinascidia turbinata. Furthermore, it was established that Phallusia nigra has extended its distributional range to the north of the Aegean Sea.

Published: May 2013

Spatial distribution and ecology of the larvae of three tuna species (Thunnus thynnus, Auxis rochei and Euthynnus alletteratus) were studied during an ichthyoplankton survey carried out in the Gulf of Gabes (Tunisia) in June and July 2009. A total of 80 stations, distributed on a regular sampling grid, were sampled. The main objectives of this survey were to provide information on tuna larvae distribution in the Gulf of Gabes in relation to the environmental parameters. Regarding small tunas, larvae of A. rochei (bullet tuna) showed the more widespread distribution, being found at both inshore and offshore stations. E. alletteratus (Atlantic black skipjack) larvae were mainly found at the inshore stations covering the wide continental shelf of this region. On the other hand, larvae of the large migratory tuna T. Thynnus (Atlantic bluefin tuna), were mainly recorded at offshore stations, suggesting that spawning possibly takes place mainly near the shelf break. Regarding the biological and physical parameters examined, our results indicate that tuna larvae were mainly collected in oligotrophic and mixed waters resulting from the confluence of surface water of recent Atlantic origin and resident surface Mediterranean waters, as shown by their preference for lower chlorophyll a concentrations (from 1.4 to 2.5 mg m-3) and moderate salinity values (between 37.35 and 37.75). Significantly, tuna larvae seemed to avoid the more eutrophic and saltier waters of the gulf situated very close to the coast and around Kerkennah and Djerba islands.
Comparative distribution of the fan mussel Atrina fragilis (Bivalvia, Pinnidae) in protected and trawled areas of the north Aegean Sea (Thermaikos Gulf)
Authors: FRYGANIOTIS K. , ANTONIADOU C. , CHINTIROGLOU C.
Published: May 2013

The distribution of the fan mussel Atrina fragilis was studied at two contrasting areas of the north Aegean Sea (Thermaikos Gulf): one routinely trawled and one closed to trawlers for over 25 years. Significant differences were detected between the two areas with decreased values in density and size of A. fragilis individuals at the trawled area. As habitat differences, i.e. sediment composition and bathymetry, had non-significant effect, extensive trawling activities probably explain the observed results.
Effects of habitat and substrate complexity on shallow sublittoral fish assemblages in the Cyclades Archipelago, North-eastern Mediterranean Sea
Authors: GIAKOUMI S. , KOKKORIS G.D.
Published: May 2013

This is the first study to explore fish community structure and its relations to habitat and topographic complexity in the shallow coastal waters of the Cyclades Archipelago, North-eastern Mediterranean Sea. In situ visual surveys were carried out at 233 sampling sites in 26 islands of the Cyclades Archipelago. Fish community parameters and biomass were estimated across seven substrate types: sand, seagrass, vertical walls, boulders, horizontal/subhorizontal continuous rock, rocky substrate with patches of sand, and rocky substrate with patches of sand and Posidonia oceanica. Topographic complexity and percentage of algal cover were estimated on hard substrate. Substrate type was found to be a determining factor affecting the structure and composition of fish assemblages. Species number, abundance and biomass were significantly lower in sandy areas and always higher on hard substrates, with seagrass habitats presenting intermediate values. Topographic complexity in rocky bottoms did not seem to affect species richness, density or biomass. This study provides a baseline for future evaluation of changes produced by potential management actions such as the creation of marine protected areas in the study region.
Biological aspects and ecological effects of a bed of the invasive non-indigenous mussel Brachidontes pharaonis (Fischer P., 1870) in Malta
Authors: BONNICI L. , EVANS J. , BORG J.A. , SCHEMBRI P.J. J.
Published: May 2013

No mussel beds were known to occur in the Maltese Islands previous to 2009, when a single bed of the Lessepsian immigrant Brachidontes pharaonis, first recorded from the islands in 1970, was discovered in Birzebbugia Bay. The population structure of B. pharaonis was investigated to assess its potential to spread and colonise new shores, while the biotic community at the mussel bed was compared to that present on uncolonised substratum to determine the effects of mussel bed establishment on the associated biota. Results indicate a lower species richness and slightly different community structure with greater small-scale heterogeneity at the mussel bed site compared to the adjacent rocky shore where mussels are present but where there is no bed formation. The B. pharaonis population had a peak density of 16550 ± 2051 ind.m-2 within the mussel bed and included recent recruits. These data suggest that the B. pharaonis population has the potential to expand. Establishment of extensive beds by this invasive mussel could change the structure of native rocky shore assemblages around the Maltese Islands and elsewhere in the Mediterranean.

Published: May 2013

Compared to their shelf-living relatives, the biology and ecology of most pelagic and deep-sea cephalopods is currently rather unknown owing to the difficulties to catch them. To cover the lack of information on these cephalopods, scientists have to make use of the limited and fragmentary data gathered from different sources such as sporadic captures, strandings or stomach contents of their predators. Here, we give some biological and ecological information on eleven uncommon pelagic and deep-sea cephalopods collected during more than fifteen years of fisheries surveys in the western Mediterranean Sea. The cephalopods investigated include two epipelagic octopuses (Ocythoe tuberculata and Tremoctopus violaceus), one deep-sea cirrate octopus (Opisthoteuthis calypso), the sepiolid Stoloteuthis leucoptera and seven teuthoid species inhabiting preferentially mesopelagic and bathypelagic waters (Abraliopsis morisii, Ancistrocheirus lesueurii, Brachioteuthis riisei, Chiroteuthis veranyi, Chtenopteryx sicula, Onychoteuthis banksii and Taonius pavo). Although all of these species are either cosmopolitan or present a wide distribution in other oceans, they are nevertheless relatively rare in catches, and therefore remain poorly known. The finding of T. pavo represents the first record of this cephalopod in the Mediterranean.

Published: May 2013

In this study, the growth parameters of the four-spotted megrim, (Lepidorhombus boscii Risso, 1810), were studied in Saros Bay, which had been closed to bottom trawl fishery since 2000. The sex ratio of females to males was 1:0.42. Length-weight relationships were W=0.0032L3.31 and W=0.0069L3.04 for females and males, respectively. Growth parameters of the populations were L∞=49.8 cm, k=0.09 year-1, t0=-2.15 year for females; L∞=39.1 cm, k=0.11 year-1, t0=-2.59 year for males. The growth performance index (Φ’) was found to be 2.35 and 2.23 for females and males, respectively.
ELNAIS meets EASIN: distribution of marine alien species in Greece using EASIN mapping services and ELNAIS spatial data

Published: May 2013

The European Alien Species Information Network (EASIN) was created with the aim to provide easy access to accurate information on alien species in Europe. EASIN allows the retrieval of spatial information from existing online data providers in order to produce integrated georeferenced distribution maps of alien species in Europe. In November 2012, a new data provider, the Ellenic Network on Aquatic Invasive Species (ELNAIS), joined EASIN; this has significantly increased the available georeferenced information on marine/estuarine alien species in Greek waters. Here, we use maps created by EASIN to show differences in patterns of distribution in Greece for the most abundant Phyla of marine alien species - Mollusca, Arthropoda, Chordata and Annelida. We also show that the two main pathways of introduction of marine alien species (Lessepsian migration and Shipping) are related to different patterns of species spatial distribution in Greece. Overall, the tools provided by EASIN can greatly aid scientists and policy makers in obtaining high quality information on marine alien species in Greece, especially after the association with ELNAIS.
First report of the North Atlantic myrionematoid brown alga Ulonema rhizophorum Foslie (Phaeophyceae, Chordariaceae) in the Mediterranean Sea
Authors: TASKIN E.
Published: May 2013

The myrionematoid brown alga Ulonema rhizophorum Foslie (Phaeophyceae, Chordariaceae) is reported for the first time from the Mediterranean Sea. This species was collected growing as an epiphyte on Ulva sp. from the Dardanelles (Sea of Marmara, Turkey) in the midlittoral zone. Ulonema rhizophorum is characterized by downwardly produced rhizoids from the basal system. A key to the Mediterranean related genera of Ulonema is provided.

Published: May 2013

The variation of the smaller size fraction of zooplankton was investigated during a two-year period in a brackish deep and anoxic coastal lake of western Greece (Aitoliko), along with the specific environmental characteristics of this ecosystem. The zooplanktonic community comprised a relatively small number of taxa and it was dominated by brackish-water calanoid copepods (Paracartia latisetosa, Calanipeda aquaedulcis) and in certain periods by rotifers and tintinnids. The zooplankton abundance showed an increase in the warmer period starting from late spring and reached maximum values in July. In the well oxygenated surface layer, temperature was the most important parameter influencing the seasonal cycles of all groups. In contrast, the oxygen depletion a few meters under the surface affected the vertical distribution of most of the zooplankton groups, which were found restricted in the surface layer especially from spring until autumn. Only the meroplanktonic larvae of polychaetes presented increased proportions in the deeper layers. Salinity has not significantly influenced the zooplanktonic assemblages. The results point out the degraded status of the Aitoliko basin where the hypoxic/anoxic layers resulted to a high portion of dead organic material identified as copepod carcasses, and underlines the necessity of monitoring of this ecosystem.
Pelvic fin walking and punting behaviour of Raja radula Delaroche, 1809 observed in the Sea of Marmara
Authors: BILECENOGLU M. , EKSTROM L. J.
Published: May 2013

A mature female rough ray (Raja radula Delaroche, 1809) individual was observed at Sea of Marmara during a scuba dive to perform pelvic fin walking and punting, which was a previously unrecorded rajid behaviour from the Mediterranean Sea. The underwater video footage were analyzed, in which the average distance travelled per punt was measured as 0.40 disc length (DL) at an average speed of 0.26DL per second.
Is Posidonia oceanica regression a general feature in the Mediterranean Sea?
Authors: BONACORSI M. , PERGENT-MARTINI C. , BREAND N. , PERGENT G.
Published: May 2013

Over the last few years, a widespread regression of Posidonia oceanica meadows has been noticed in the Mediterranean Sea. However, the magnitude of this decline is still debated. The objectives of this study are (i) to assess the spatio-temporal evolution of Posidonia oceanica around Cap Corse (Corsica) over time comparing available ancient maps (from 1960) with a new (2011) detailed map realized combining different techniques (aerial photographs, SSS, ROV, scuba diving); (ii) evaluate the reliability of ancient maps; (iii) discuss observed regression of the meadows in relation to human pressure along the 110 km of coast. Thus, the comparison with previous data shows that, apart from sites clearly identified with the actual evolution, there is a relative stability of the surfaces occupied by the seagrass Posidonia oceanica. The recorded differences seem more related to changes in mapping techniques. These results confirm that in areas characterized by a moderate anthropogenic impact, the Posidonia oceanica meadow has no significant regression and that the changes due to the evolution of mapping techniques are not negligible. However, others facts should be taken into account before extrapolating to the Mediterranean Sea (e.g. actually mapped surfaces) and assessing the amplitude of the actual regression.
The nematode assemblage as a tool for the assessment of marine ecological quality status: a case-study in the Central Adriatic Sea

Published: May 2013

Free-living nematodes are efficiently used as bio-indicators of anthropogenic disturbance in marine ecosystems. Among various criteria, functional traits may represent useful tools for monitoring environmental impact in coastal areas. A study of nematode assemblages was carried out in three locations of the Central Adriatic Sea (Italy), one at the mouth of the Foglia River (Baia Flaminia) and two enclosed in the Monte San Bartolo Natural Park (Monte Brisighella and Fiorenzuola di Focara). Taxonomic composition and the functional traits of the nematode assemblage revealed a possible influence of the organic load of the Foglia River. Biotic data, as well as environmental parameters, suggested a particularly negative impact of the river on the assemblage at Baia Flaminia. Here, the increasing impact of the river led to a rise in the relative abundance of r-strategist genera like Chromadora, Sabatieria and Viscosia. Poor ecological conditions were also present at Brisighella, where the river might exert its influence due to the presence of long shore currents. In contrast, the results revealed that the best ecological quality was at Fiorenzuola di Focara, where the impact of anthropogenic activities was generally irrelevant. This study documents how nematodes can be used as an early warning indicator with which to monitor the health quality of vulnerable littoral areas.

Published: May 2013

The Croatian part of the Adriatic Sea covers more than 35% of the total Croatian territory, which means that monitoring changes in marine ecosystems and the conservation of biodiversity are of great importance. Following global changes, Croatia is experiencing increasing problems due to the introduction of new species that include aliens (due to aquaculture activities and shipping) and species from other Mediterranean subregions that are extending their geographic range. This work provides a checklist of introduced species in Croatian waters. A total of 113 species (15 phytoplankton, 16 zooplankton, 16 macroalgae, 44 zoobenthic and 22 fish species) have been recorded in the eastern part of the Adriatic Sea, of which 61 species are alien and 52 introduced, due to climate change.

This paper concerns records of species that have extended their distribution in the Mediterranean Sea. The finding of the rare brackish angiosperm Althenia filiformis in the island of Cyprus is interesting since its insertion in the Red Data Book of the Flora of Cyprus is suggested. The following species enriched the flora or fauna lists of the relevant countries: the red alga Sebdenia dichotoma (Greece), the hydrachnid mite Pontarachna adriatica (Slovenia), and the thalassinid Gebiacantha talismani (Turkey). Several alien species were recorded in new Mediterranean localities. The record of the burrowing goby Trypauchen vagina in the North Levantine Sea (Turkish coast), suggests the start of spreading of this Lessepsian immigrant in the Mediterranean Sea. The findings of the following species indicate the extension of their occurrence in the Mediterranean Sea: the foraminifer Amphistegina lobifera (island of Zakynthos, Greece), the medusa Cassiopea andromeda (Syria), the copepod Centropages furcatus (Aegean Sea), the decapod shrimp Melicertus hathor (island of Kastellorizo, Greece), the crab Menoethius monoceros (Gulf of Tunis), the barnacles Balanus trigonus, Megabalanus tintinnabulum, Megabalanus coccopoma and the bivalves Chama asperella, Cucurbitula cymbium (Saronikos Gulf, Greece).
Product Design for the Long Run: Consumer Responses to Typical and Atypical Designs at Different Stages of Exposure
Authors: Landwehr Jan R. , Wentzel Daniel , Herrmann Andreas
Published: May 2013

Extant research on product design has suggested that a design's typicality is an important determinant of consumers' aesthetic liking. Yet most studies to date have measured consumers' reactions to designs of varied typicality after a single exposure. In reality, however, consumers usually have multiple opportunities to observe a product before making a decision. Against this background, the authors perform three studies in the automobile domain that examine whether the positive effect of design typicality is moderated by the level of exposure. Study 1 indicates that aesthetic liking of typical car designs is greater at lower exposure levels, whereas people like atypical car designs better at higher exposure levels. Study 2 uses real sales data and indicates that the interaction between design typicality and exposure also affects sales, suggesting that atypical cars may be more successful in the long run. Using experimental manipulations of the key constructs, Study 3 provides evidence for the underlying process and finds renewed support for the notion that design typicality and exposure interact to affect aesthetic liking.
On Brands and Word of Mouth
Authors: Lovett Mitchell J. , Peres Renana , Shachar Ron
Published: May 2013

Brands and word of mouth (WOM) are cornerstones of the marketing field, and yet their relationship has received relatively little attention. This study aims to enhance understanding of brand characteristics as antecedents of WOM by executing a comprehensive empirical analysis. For this purpose, the authors constructed a unique data set on online and offline WOM and characteristics for more than 600 of the most talked-about U.S. brands. To guide this empirical analysis, they present a theoretical framework arguing that consumers spread WOM on brands as a result of social, emotional, and functional drivers. Using these drivers, the authors identify a set of 13 brand characteristics that stimulate WOM, including three (level of differentiation, excitement, and complexity) that have not been studied to date as WOM antecedents. The authors find that whereas the social and functional drivers are the most important for online WOM, the emotional driver is the most important for offline WOM. These results provide an insightful perspective on WOM and have meaningful managerial implications for brand management and investment in WOM campaigns.
Temporal Contiguity and Negativity Bias in the Impact of Online Word of Mouth
Authors: Chen Zoey , Lurie Nicholas H.
Published: May 2013

Prior research shows that positive online reviews are less valued than negative reviews. The authors argue that this is due to differences in causal attributions for positive versus negative information such that positive reviews tend to be relatively more attributed to the reviewer (vs. product experience) than negative reviews. The presence of temporal contiguity cues, which indicate that review writing closely follows consumption, reduces the relative extent to which positive reviews are attributed to the reviewer and mitigates the negativity bias. An examination of 65,531 Yelp.com restaurant reviews shows that review value is negatively related to review valence but that this negative relationship is absent for reviews that contain temporal contiguity cues. A series of lab studies replicates these findings and suggests that temporal contiguity cues enhance the value of a positive review and increase the likelihood of choosing a product with a positive review by changing reader beliefs about the cause of the review.
Association of combined features of amino acid and protein withcrystallization propensity of proteins fromCytophaga Hutchinsonii
Authors: Yan Shaomin , Wu Guang
Published: May 2013

Various features of amino acids have been so far associated with crystallization propensity of proteins. The majority of features generally represents a certain aspect of individual amino acid, for example, molecular weight of an amino acid. Meanwhile, a small portion of features, which represents a certain aspect of a whole protein, is also associated with crystallization propensity of proteins, such as protein length. Clearly, the features of individual amino acids distinguish themselves from the features of a whole protein. Therefore it would be more rationale to use the features, which combine both features of individual amino acids and a whole protein, to associate crystallization propensity of proteins, because the features of individual amino acids are not subject to amino acids‘ positions in a protein, for instance. In this study, each of three combined features of individual amino acids and a whole protein are associated with crystallization propensity of proteins fromCytophaga Hutchinsoniithrough logistic regression and neural network, and each of 535 features of individual amino acids is also associated with crystallization propensity of the proteins to serve as benchmark. The results show that the combined features have a good relationship with crystallization propensity of proteins fromCytophaga Hutchinsonii. This study provides the information that the combined features can be used for predicting crystallization propensity of protein.

Published: May 2013

This review describes the input of sol-gel chemistry to the immobilization of polyol dehydrogenases on electrodes, for applications in bioelectrocatalysis. The polyol dehydrogenases are described and their application for biosensing, biofuel cell and electrosynthesis are briefly discussed. The immobilization of proteins via sol-gel approaches is described, including a discussion on the difficulty to maintain the activity of proteins in a silica matrix and the strategies developed to offer a proper environment to the proteins by developing optimal organic-inorganic hybrid materials. Finally, the co-immobilization of the NAD
+
co-factor and of mediators for the elaboration of reagentless devices is presented, based on published and original data. All-in-all, sol-gel approaches appear to be a very promising for development of original electrochemical applications involving dehydrogenases in near future.
Acridine – a Promising Fluorescence Probe of Non-Covalent Molecular Interactions
Authors: Rozhkova Yulia , Gurinov Andrey A. , Tolstoy Peter M. , Denisov Gleb S. , Shenderovich Ilya G. , Korotkov Valentin Ivanovich
Published: May 2013

Fluorescence and absorption spectral parameters of acridine have been studied in solution at room temperature in the presence of different proton donors aiming to inspect whether or not acridine can be used as a spectroscopic probe suitable to measure the geometry of hydrogen bonds under different conditions. It has been shown that the most appropriate spectral parameter is the position of fluorescence maximum that changes heavily upon a contraction of the N···H distance. Presumably, also the intensity of the maximum strongly depends on the hydrogen bond geometry. These two parameters can be used to establish two independent, mutually complementary correlations connecting the spectral manifestations and the geometry of hydrogen bond.

Published: May 2013

Background: The prevalence of gastric polyps is unknown in Hungary. Aim: The aim of the authors was to assess the prevalence of polypoid lesions of the stomach in the endoscopic centre of the 2nd Department of Medicine, Semmelweis University. Methods: Results of upper gastrointestinal endoscopies carried out between March 2010 and June 2011 were analysed. Results: 193 cases with polyps were diagnosed in 4174 endoscopies (4.62%). Hyperplastic polyps, fundic gland polyps and malignant lesion were detected in 33.67%, 31.09% and 2.07% of the cases, respectively. Proton pump inhibitor use was more frequent among patients diagnosed with fundus gland polyps (p = 0.007), while hyperplastic polyps were diagnosed more frequently in patients with chronic gastritis (p = 0.032). Conclusions: The frequency of gastric polyps was higher than expected from data published in the literature. Long-term proton pump-inhibitor use and chronic gastritis were associated with fundus gland and hyperplastic polyps, respectively. Orv. Hetil., 2013, 154, 770–774.
O uso da entrevista na pesquisa-intervenção participativa em saúde mental: o dispositivo GAM como entrevista coletiva
Authors: Sade Christian , Barros Leticia Maria Renault de , Melo Jorge José Maciel , Passos Eduardo
Published: May 2013

O artigo propõe-se a discutir um modo de fazer entrevista em sintonia com o ideário da Reforma Psiquiátrica brasileira. Na metodologia de uma pesquisa-intervenção participativa da saúde mental, a entrevista é um procedimento menos de coleta do que de colheita de dados; voltada ao cultivo dos princípios da atenção psicossocial, da autonomia como direção do tratamento, do protagonismo do usuário e de sua rede social e de sua participação cidadã. Inspirados na técnica da entrevista de explicitação, entendemos que o manejo da entrevista supõe uma atitude de abertura capaz de promover e acolher diferentes pontos de vista. Tal atitude faz da entrevista uma experiência coletiva, de compartilhamento e de pertencimento, permitindo que os participantes se reposicionem subjetivamente e que haja a contração de grupalidade. Como exemplo do emprego da entrevista como ferramenta metodológica na investigação em saúde mental é citada a pesquisa de adaptação do dispositivo Gestão Autônoma da Medicação (GAM). É uma abordagem de intervenção norteada por princípios que valorizam a autonomia e o protagonismo dos usuários de psicofármacos, a sua qualidade de vida, os seus direitos e o reconhecimento das significações plurais da medicação e entendido aqui como uma prática de entrevista coletiva.
Empoderamento de usuários e familiares em saúde mental e em pesquisa avaliativa/interventiva: uma breve comparação entre a tradição anglo-saxônica e a experiência brasileira
Authors: Vasconcelos Eduardo Mourão
Published: May 2013

O objeto deste artigo são as principais características das tradições e experiências de empoderamento de usuários e familiares em abordagens e serviços de saúde mental em países anglo-saxônicos e no Brasil, e suas repercussões e estratégias no campo da pesquisa avaliativa e interventiva em saúde mental. O objetivo é comparar, através de uma breve revisão bibliográfica da literatura, como as tradições de empoderamento se desenvolveram nos dois cenários, a partir de características do contexto econômico, político, social e particularmente cultural. A revisão mostrou como estes contextos geram diferentes perspectivas de valorização da autonomização e empoderamento de usuários e familiares nas políticas sociais em geral e em saúde mental, como também nas apropriações no campo da pesquisa avaliativa e interventiva em saúde mental. Nos países anglo-saxônicos, esta tradição vem se desenvolvendo fortemente há cerca de 4 décadas, e no Brasil as estratégias participacionistas enfatizam mecanismos mistos - profissionais, usuários e familiares juntos -, com a presença dominante dos profissionais, e as iniciativas mais diretamente desenhadas para os usuários e familiares são muito recentes, a partir de 2005.

Narrativas são cada vez mais frequentes em estudos qualitativos para compreender experiências e diferentes visões de sujeitos num dado contexto. Partindo desta concepção, faz-se o resgate de tradições que abordam a narratividade - a filosofia de Paul Ricoeur, a perspectiva histórica em Walter Benjamin e o campo da antropologia médica constituída a partir da fenomenologia. Em Ricoeur, tendo a hermenêutica como pensamento derivado e variante da fenomenologia, a narrativa é ligada à temporalidade. Em Benjamin, a narrativa, sempre inconclusa, feita de restos e fragmentos, emerge à revelia das histórias oficiais. Se Ricoeur retoma de Gadamer a tradição como componente fundamental para a construção de um mundo do texto com que se torna possível a imitação da vida, Benjamin, diante da derrocada da tradição, aponta para a invenção de formas narrativas fora dos cânones tradicionais, possibilitando retomar o passado para transformar o presente. Apresentam-se ainda pressupostos da antropologia médica, que considera a narrativa como dimensão do vivido e não sua abstração, ou seja, uma narrativa corporificada e situada. Por fim, apresentam-se três pesquisas distintas em saúde mental que se utilizam de narrativas, articuladas às correntes teóricas apresentadas, com suas diferenças e aproximações.

Detivemo-nos sobre as particularidades das abordagens etnográficas na pesquisa em saúde mental, destacando razões pelas quais o tipo de conhecimento que a etnografia produz é relevante no contexto da Reforma Psiquiátrica e da biomedicalização da existência. Centramos nossa discussão na etnografia de base interpretativa no campo da saúde mental, enfatizando as bases teórico-metodológicas de um tipo compreensivo de apreensão do objeto que se aproxima de uma clínica do sujeito. Apontamos a centralidade do social/cultural na apreensão etnográfica e as inflexões desta mediadas pelo próprio tipo de empreendimento metodológico etnográfico. Finalmente, tomamos a etnografia da loucura como objeto exemplar para evidenciar algumas dessas particularidades. Argumentamos que acessar pessoas psicóticas (ou outras que venham a falar dessas experiências) de lugares variados no seu cotidiano e situadas a partir de suas diversas inscrições sociais e, ao mesmo tempo, confrontar essas interpretações com outras dimensões interpretativas da sua realidade social e dentro das lógicas afeitas às suas psicologias locais é um procedimento relevante de onde certos aspectos do entendimento sobre a loucura (ou sobre as razões da sua incompreensão) podem emergir.

Em um contexto de altas taxas de medicalização da população e face ao uso pouco crítico de medicamentos psiquiátricos em serviços de saúde mental, este artigo reporta aspectos de uma pesquisa qualitativa que teve a oportunidade de intervir em práticas de cuidado em três grandes cidades do Brasil. Seguindo o princípio da Reforma Psiquiátrica brasileira da defesa dos direitos do usuário em participar das decisões sobre seu tratamento, a pesquisa interveio nos centros de atenção psicossocial (CAPS) buscando o "empoderamento" dos usuários em relação ao uso de medicamentos em seus projetos terapêuticos. Foram realizados entrevistas e grupos focais. A partir desse material registrado, o artigo analisou algumas situações que atestaram, entre outras, a dificuldade de evitar o uso do poder sobre os usuários por via da administração de medicamentos psicotrópicos. Também se percebeu, nos serviços pesquisados, pouco diálogo sobre os medicamentos e a existência de espaços de estigmatização onde os direitos dos usuários são inibidos ou aceitos com cautela

O artigo parte da experiência de pesquisar com usuários de saúde mental (e não sobre eles, ou para eles), narrando cenas de um estudo no qual se colocaram em jogo modos distintos de articulação entre pesquisa e clínica, problematizando suas fronteiras e as questões éticas implicadas. Situa o campo da clínica e da pesquisa de que se trata com o aporte de autores que, desde a análise institucional, propõem a ideia de pesquisa-intervenção; e, no contexto da saúde coletiva, resgatam o conceito de clínica ampliada. Fundamenta-se a articulação entre esses dois termos - pesquisa-intervenção e clínica ampliada - desde a noção de subjetividade que opera no âmbito da saúde coletiva e que culmina na ideia de autonomia. Finalmente, propõe-se a cogestão como estratégia a partir da qual os diferentes atores implicados na condução da pesquisa e no exercício da clínica constroem coletivamente uma direção de trabalho, ao mesmo tempo terapêutica e ética.

O tema dos direitos dos usuários ganha centralidade na discussão contemporânea no campo da saúde mental. A partir da criação de um Comitê Cidadão, composto por usuários e familiares em uma aliança de pesquisa internacional entre Brasil e Canadá, propomos discutir os efeitos, nestes sujeitos, da experiência de cogestão promovida pela pesquisa participativa "Gestão Autônoma da Medicação (GAM)". Através de descrição detalhada do histórico do Comitê e de entrevista e análise de transcrição da voz de seus membros, problematizamos a relação dialogada entre o saber científico e o saber advindo da experiência singular destes sujeitos, em uma perspectiva metodológica de pesquisa participativa. Como resultado da pesquisa, observamos que a experiência do Comitê Cidadão na cogestão da pesquisa em saúde pode ser propiciadora do aumento nos graus de autonomia, maior empoderamento e exercício de protagonismo e cidadania, com a consequente emergência de sujeitos de direitos.

É típico da população idosa a prevalência elevada de doenças crônicas, que comprometem a sua autonomia. Um exemplo são as síndromes demenciais. O objetivo deste trabalho é projetar o número de idosos demenciados. Para isto estimou-se o número atual, aplicando medidas de prevalência por grupos de idade à população de 65 anos e mais, enumerada pelo Censo Demográfico de 2010. Estas medidas fora\m obtidas nos levantamentos encontrados na literatura. Para se obter uma medida nacional, utilizou-se uma média ponderada das prevalências estimadas. Foram obtidas taxas de prevalência por idade e sexo para a população idosa brasileira. Pesquisas existentes mostram que a demência cresce acentuadamente com a idade. As mulheres e os analfabetos apresentam uma prevalência mais elevada. A prevalência brasileira média apresenta-se mais alta que a mundial. Projeções para a população brasileira apontam para um pequeno crescimento na taxa de prevalência de demência na população com 65 anos e mais, de 7,6% para 7,9% entre 2010 e 2020, ou seja, 55.000 novos casos por ano. As demências constituem uma questão de saúde pública e trazem uma preocupação bioética com o envelhecimento: a perda da autonomia das pessoas afetadas e a responsabilidade do sistema de saúde para atendê-las.
The prevalence of medical/clinical technology over psychosocial care actions in outpatient mental health services
Authors: Fiorati Regina Celia , Saeki Toyoko
Published: May 2013

The scope of this study was to evaluate how aspects of mental health policy in Brazil have been conceived and implemented in outpatient services, such as the Regional Outpatient Mental Health Clinic and the Psychosocial Care Center II, both in Ribeirão Preto, São Paulo. Semi-direct interviews and focus groups were conducted with 22 health professionals. The theoretical method and data analysis were supported by the dialectical hermeneutic framework of Jürgen Habermas. The following aspects were detected: considerable technological advancement in health actions and centrality of clinical-medical technology in relation to other nonmedical therapeutic actions; the prioritization of treatment options emphasizing pathology and drug therapy, and a process of mounting precariousness in labor relations. With respect to psychosocial rehabilitation, analysis revealed that instrumental and technically-oriented treatment is imposed upon the practical and dialogical rationale proposed by Brazilian Psychiatric Reform. As an alternative, participatory evaluative research is required in order to unify clinical and psychosocial rehabilitation actions in therapeutic projects, while establishing mechanisms to promote the improvement of care based on the psychosocial care model.
Diferentes faces da depressão no suicídio em idosos

Published: May 2013

O artigo analisa diferentes faces da depressão associadas a suicídio em idosos, a partir de autópsias psicológicas. Utilizou-se um método retrospectivo para o estudo de mortes indeterminadas, a partir de entrevistas e laudos, que analisa circunstâncias psicossociais associadas ao suicídio. O artigo traz uma predominância de gênero, classe social e raça - mulheres, classe média e alta, brancos - e contextualiza de modo inédito a depressão numa população de alto risco de suicídio, pouco estudada no Brasil e no mundo. Buscou-se reconstituir o nível de saúde física e mental, as circunstâncias sociais e os traços biográficos marcantes para compreender a magnitude da depressão no suicídio. A depressão apareceu na quase totalidade dos casos como diagnóstico primário ou secundário, como sintoma associado a outras comorbidades ou como reação a estressores sociais, demandando diferentes condutas e procedimentos terapêuticos. A associação entre depressão e comorbidade múltipla agrava o prognóstico do caso e amplia cumulativamente o risco de suicídio. A depressão acompanhada de ideações suicidas é um fator de risco que justifica medidas preventivas e imediatas. Recomenda-se ampliar as formas de diagnosticar e tratar assertivamente a depressão em idosos.

Buscou-se investigar a associação da violência psicológica (VP) na adolescência com fatores sociodemográficos, estrutura/relacionamento familiar e com outras formas de maus-tratos. Aplicou-se em 229 adolescentes (11-18 anos) um questionário, em serviços ambulatoriais de um hospital pediátrico público terciário. Encontrou-se que 26,4% dos entrevistados sofrem VP severa no contexto familiar, sendo que apenas cinco relataram não sofrer qualquer tipo de VP familiar, sugerindo que essa violência é considerada como uma forma corriqueira de relacionamento familiar. Comportamentos de VP familiares mais relatados: ser criticado pelo que faz ou diz, não ser encorajado quando tenta atuar de forma autônoma, ser chamado por nomes desagradáveis e ter adulto dizendo que está errado ao tentar agir. Insatisfação dos responsáveis com o adolescente, a estrutura familiar nuclear, a posição da criança entre os irmãos e o compartilhamento dos mesmos pais pelos irmãos mostraram-se associados à VP que ocorre no contexto familiar. O setor saúde, capacitando-se para detectar os sinais de VP, pode promover o direito à saúde integral de adolescentes, confirmando ser um dos principais setores sociais capazes de atuar preventivamente sobre as formas de violência sofridas e praticadas pelo grupo familiar.

O objetivo desta investigação foi determinar a prevalência de amputações por pé diabético e analisar associações com fatores relacionados à pessoa e à atenção básica. Estudo epidemiológico de corte transversal. A amostra compreendeu 214 portadores de pé diabéticos internados em um dos quatro hospitais com especialidade cirurgia vascular de Pernambuco. Os dados foram coletados mediante questionário semiestruturado. Na análise dos dados foram aplicados os procedimentos da estatística descritiva, análise de associações de qui-quadrado e de regressão de poisson (p < 0,05). A prevalência de amputações encontrada foi de 50%. Estiveram associados à sua ocorrência fatores relacionados à pessoa: baixa escolaridade (p = 0,027), duas ou mais pessoas residentes no domicílio (p = 0,046) e renda do paciente inferior a um salário mínimo (p = 0,004). Dos fatores relacionados à atenção básica: não ter os pés examinados (RP = 1,17) e não ter recebido orientações sobre os cuidados com os pés (RP = 2,24) nas consultas realizadas no último ano, além de não usar o medicamento para controle do DM conforme prescrição (RP = 1,60) e controle inadequado da glicemia (RP = 1,83) foram associados à ocorrência de amputações. A compreensão desses fatores ajuda a identificar aspectos da assistência preventiva que precisam ser melhorados.

The scope of this paper was to analyze the profile of medical consultations and drugs used for the treatment of comorbidities in patients with diabetes attended in the Brazilian Unified Health System. This was a pharmaco-epidemiological cross-sectional study conducted between March 2006 and February 2007 All patients with diabetes attended in the western sanitary district of Ribeirao Preto in the state of São Paulo were included in the study. The types of medical attendance (primary, secondary and emergency care) and the drugs prescribed for the treatment of comorbidities were analyzed. The drugs were classified according to the Anatomical Therapeutic Chemical Classification System and 3,198 patients were identified. The mean age was 60.4 years and more than 55% of the patients were 60 years or older. The cardiovascular drugs most used were captopril or enalapril (60%). About 40.6% of the patients used acetylsalicylic acid in platelet antiaggregant doses. The patients had an average of 5.1 medical consultations per year (primary care, secondary care and emergency care). The utilization of statins and acetylsalicylic acid was less than that reported in the literature and the data indicate a high prevalence of admission to emergency care.
