Container productivity, daily survival rates and dispersal of Aedes aegypti mosquitoes in a high income dengue epidemic neighbourhood of Rio de Janeiro: presumed influence of differential urban structure on mosquito biology

Different urban structures might affect the life history parameters of Aedes aegypti and, consequently, dengue transmission. Container productivity, probability of daily survival (PDS) and dispersal rates were estimated for mosquito populations in a high income neighbourhood of Rio de Janeiro. Results were contrasted with those previously found in a suburban district, as well as those recorded in a slum. After inspecting 1,041 premises, domestic drains and discarded plastic pots were identified as the most productive containers, collectively holding up to 80% of the total pupae. In addition, three cohorts of dust-marked Ae. aegypti females were released and recaptured daily using BGS-Traps, sticky ovitraps and backpack aspirators in 50 randomly selected houses; recapture rate ranged from 5-12.2% within cohorts. PDS was determined by two models and ranged from 0.607-0.704 (exponential model) and 0.659-0.721 (non-linear model), respectively. Mean distance travelled varied from 57-122 m, with a maximum dispersal of 263 m. Overall, lower infestation indexes and adult female survival were observed in the high income neighbourhood, suggesting a lower dengue transmission risk in comparison to the suburban area and the slum. Since results show that urban structure can influence mosquito biology, specific control strategies might be used in order to achieve cost-effective Ae. aegypti control.

Integrating Metalib and SFX into the BV-SSPA

Introduction To guarantee the success of a virtual library it is essential that all users can access all the library resources independently of the user’s location. Achieving this goal in the Andalusian Public Health System has been a particularly difficult task, due to it is made up of 10 research centers and 95.000 health-care professionals. Aims Since the BV-SSPA started three years ago, one of its mayor aims has been to provide remote access to all its resources in this complex scenario, as well as facilitate the access to the virtual library to both professionals and citizens. IP access was guaranteed because health-care professionals could access everything from their workplaces thanks to the intranet, but it was restricted when they were not there. The BV-SSPA solved this problem by installing a federated authentication and authorization system called PAPI and a PAPI rewriting proxy. After three years the BV-SSPA has met a new challenge: adapting its federated access system to Metalib and SFX, specifically the access management module PDS had to be connected with the existing PAPI system. This new challenge came along with the introduction of a new metasearcher and link resolver. Material and Methods Initially there were three independent systems: • A Metalib and SFX PDS module, • A federated authentication and authorization system: PAPI. • A PAPI Rewriting Proxy. The chosen solution went through the reutilization of the existing software. To achieve this goal, a PHP connector between these applications was developed and several modules in the PDS configuration were modified. On the other hand, providing a simplified access to Metalib has been solved using Xerxes and integrating it in a Drupal website. Results Thanks to this connector the BV-SSPA was able to get all its users remotely accessing its new metasearcher without changing the way they used to validate, or without having to remember a new username and password. Futhermore, thanks to Xerxes, it is possible to use Metalib from a simple interface and without having to leave the BV-SSPA website to go its native interface.

Personality disorders and the Five-Factor Model among French speakers in Africa and Europe

Objective: Several authors have suggested that Personality Disorders (PDs) might be more accurately described using a dimensional model instead of a categorical one. The aim of this study was to describe the relationship between PDs and the Five-Factor Model (FFM)-a dimensional model describing normal personality traits known for its invariance across cultures-in two different cultural settings. Method: Subjects from nine French-speaking African countries (n = 2,014) and from Switzerland (n = 697) completed both the French-version of the IPDE screening questionnaire, assessing the ten DSM-IV PDs, and the French-version of the NEO-PI-R, assessing the five domains and thirty facets of the FFM. Results: Correlations between PDs and the five domains of the FFM were similar in both samples. For example, Neuroticism was highly correlated with Borderline, Avoidant, and Dependent PDs in both Africa and Switzerland. The total rank-order correlation (rho) between the two correlation matrices was very high (rho = 0.93) and significant (P < 0.001), as were the rhos for all domains of the FFM and all PDs, except Paranoid and Dependent PDs. However, the rhos for PDs across facet-scales were all highly significant (P < 0.001). Moreover, 80% of Widiger and colleagues' predictions and 70 % of Lynam and Widiger's prototypes, concerning the relationship between PDs and the FFM, were confirmed in both samples. Conclusions: The relationship between PDs and the FFM was stable in two samples separated by a great cultural distance. These results suggest that a dimensional approach and in particular the FFM might be useful for describing PDs in a variety of cultural settings.

The potential of the European network of congenital anomaly registers (EUROCAT) for drug safety surveillance: a descriptive study.

BACKGROUND: European Surveillance of Congenital Anomalies (EUROCAT) is a network of population-based congenital anomaly registries in Europe surveying more than 1 million births per year, or 25% of the births in the European Union. This paper describes the potential of the EUROCAT collaboration for pharmacoepidemiology and drug safety surveillance. METHODS: The 34 full members and 6 associate members of the EUROCAT network were sent a questionnaire about their data sources on drug exposure and on drug coding. Available data on drug exposure during the first trimester available in the central EUROCAT database for the years 1996-2000 was summarised for 15 out of 25 responding full members. RESULTS: Of the 40 registries, 29 returned questionnaires (25 full and 4 associate members). Four of these registries do not collect data on maternal drug use. Of the full members, 15 registries use the EUROCAT drug code, 4 use the international ATC drug code, 3 registries use another coding system and 7 use a combination of these coding systems. Obstetric records are the most frequently used sources of drug information for the registries, followed by interviews with the mother. Only one registry uses pharmacy data. Percentages of cases with drug exposure (excluding vitamins/minerals) varied from 4.4% to 26.0% among different registries. The categories of drugs recorded varied widely between registries. CONCLUSIONS: Practices vary widely between registries regarding recording drug exposure information. EUROCAT has the potential to be an effective collaborative framework to contribute to post-marketing drug surveillance in relation to teratogenic effects, but work is needed to implement ATC drug coding more widely, and to diversify the sources of information used to determine drug exposure in each registry.

Psychiatric Status across Body Mass Index in a Mediterranean Spanish Population.

BACKGROUND Mental and body weight disorders are among the major global health challenges, and their comorbidity may play an important role in treatment and prevention of both pathologies. A growing number of studies have examined the relationship between psychiatric status and body weight, but our knowledge is still limited. OBJECTIVE The present study aims to investigate the cross-sectional relationships of psychiatric status and body mass index (BMI) in Málaga, a Mediterranean city in the South of Spain. MATERIALS AND METHODS A total of 563 participants were recruited from those who came to his primary care physician, using a systematic random sampling, non-proportional stratified by BMI categories. Structured clinical interviews were used to assess current Axes-I and II mental disorders according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR). BMI was calculated as weight (Kg) divided by square of height in meters (m2). Logistic regression was used to investigate the association between BMI and the presence of any mental disorder. BMI was introduced in the models using restricted cubic splines. RESULTS We found that high BMI values were directly associated with mood and adjustment disorders, and low BMI values were directly associated with avoidant and dependent personality disorders (PDs). We observed an inverse relationship between low BMI values and cluster A PDs. There were not significant relationships between anxiety or substance-related disorders and BMI. CONCLUSION Psychiatric status and BMI are related in a Mediterranean Spanish population. A multidisciplinary approach to both pathologies becomes increasingly more necessary.

Erosão em sulcos em diferentes preparos e estados de consolidação do solo

O preparo e a consolidação do solo alteram a sua capacidade em resistir à erosão em sulcos. Com o objetivo de estudar a erosão em sulcos em diferentes preparos e consolidação do solo, conhecer o diâmetro mediano dos sedimentos transportados e determinar a erodibilidade em sulcos (Kr) e a tensão crítica de cisalhamento (τc) do solo, foi realizado um experimento no campo, em 1997/98, em um Argissolo Vermelho-Amarelo distrófico arênico. O delineamento experimental foi inteiramente casualizado com seis repetições. Os tratamentos constaram de: preparo convencional recente (CR), preparo convencional consolidado (consolidação de dois meses) (CC), plantio direto sem palha (PDS) e plantio direto com palha (PDC, 94% de cobertura). Usou-se chuva simulada de intensidade constante (65 mm h-1) até escoamento aproximadamente constante de água no solo. Em seguida, na extremidade superior do sulco, foram adicionadas descargas líquidas (Q) crescentes de 0,0002 m³ s-1 até 0,0010 m³ s-1, para os tratamentos CR e CC, e de 0,0004 m³ s-1 até 0,0020 m³ s-1, para os tratamentos PDS e PDC, sendo as amostras coletadas na parte inferior de cada sulco. As parcelas foram delimitadas por chapas metálicas cravadas no solo no sentido do declive (0,20 m de largura por 6,00 m de comprimento). O valor de Kr determinado foi de 0,012 kg N-1 s-1 e o τc foi de 2,61 N m-2. A desagregação, as perdas de solo e o diâmetro mediano dos sedimentos apresentaram a seguinte seqüência em magnitude: CR, CC, PDS e PDC, particularmente nas maiores Q. O regime de escoamento foi turbulento supercrítico, com exceção da primeira Q aplicada, onde o regime foi laminar subcrítico, para o PDC, graças à presença de resíduos culturais, e laminar supercrítico, para os demais tratamentos. A consolidação e a cobertura do solo alteram o regime do escoamento e reduzem a erosão em sulcos e seus efeitos são complementares.

Erosão em entressulcos em diferentes preparos e estados de consolidação do solo

O preparo torna o solo mais susceptível à desagregação pelo impacto das gotas da chuva e transporte pelo fluxo superficial laminar e salpicamento, mas, com o passar do tempo, o solo reconsolida-se, aumentando novamente sua resistência. Com o objetivo de estudar a erosão em entressulcos, em diferentes métodos de preparo do solo e consolidação, foi realizado, em 1997/98, um experimento em um Argissolo Vermelho-Amarelo distrófico arênico, que vinha há oito anos sob plantio direto. O delineamento experimental foi inteiramente casualizado com seis repetições. Os tratamentos testados foram: preparo convencional recente (CR), preparo convencional consolidado (CC, consolidação de dois meses), plantio direto com palha (PDC, 94% de cobertura) e plantio direto sem palha (PDS). O experimento foi realizado com chuva simulada, com intensidade constante de 65 mm h-1, durante 90 min. As parcelas usadas tiveram dimensões de 0,50 m por 0,75 m e declividade média de 8,5%. Foi determinado o fator de erodibilidade do solo em entressulcos (Ki), obtendo-se o valor de 1,77 x 10(6) kg s m-4. Quanto à perda de solo, os tratamentos com preparos convencionais (CR e CC) não foram diferentes entre si, nem os com plantio direto (PDS e PDC), mas houve diferença entre esses dois grupos, havendo uma redução de sete vezes com a não-mobilização do solo. O diâmetro médio geométrico dos agregados foi significativamente menor no PDS e PDC que no CR e CC. Portanto, as perdas de solo foram reduzidas e a agregação aumentada, em virtude da longa consolidação (oito anos) e efeitos associados. O PDC reduziu a taxa constante de perda de água em 31% em relação ao PDS devido à cobertura do solo. Assim, a consolidação e a cobertura do solo reduzem, de forma complementar, as perdas de solo e água.
