A Eclosão do Turismo Sexual em Cabo Verde

O artigo pretende expor a violência resultante das opções desenvolvimentistas dos governos cabo-verdianos pós-coloniais, nomeadamente a aposta no turismo de massa. Parte-se do caso de uma jovem república em vias de ser invadida pelo turismo sexual para se esboçar a prefiguração do que a globalização significa em termos de relações Norte-Sul. Em Cabo Verde, explosões de uma sexualidade e violência juvenil não-domesticáveis, na medida em que agridem o senso moral e os interesses das famílias de classe média em processo de distanciamento sociocultural de suas origens populares, desencadeiam um conjunto de estudos financiados pelas redes internacionais de protecção social. Na esteira de um desses estudos, o artigo parte de um trabalho de campo realizado em 2005 e outro em 2010 em que se entrevista um grande número de crianças em situação de vulnerabilidade.

Efficacy and Safety of Canakinumab Vs Triamcinolone Acetonide in Patients with Gouty Arthritis Unable to Use Nonsteroidal Anti-Inflammatory Drugs and Colchicine, and On Stable Urate Lowering Therapy (ULT) or Unable to Use ULT

Background/Purpose: The primary treatment goals for gouty arthritis (GA) are rapid relief of pain and inflammation during acute attacks, and long-term hyperuricemia management. A post-hoc analysis of 2 pivotal trials was performed to assess efficacy and safety of canakinumab (CAN), a fully human monoclonal anti-IL-1_ antibody, vs triamcinolone acetonide (TA) in GA patients unable to use NSAIDs and colchicine, and who were on stable urate lowering therapy (ULT) or unable to use ULT. Methods: In these 12-week, randomized, multicenter, double-blind, double-dummy, active-controlled studies (_-RELIEVED and _-RELIEVED II), patients had to have frequent attacks (_3 attacks in previous year) meeting preliminary GA ACR 1977 criteria, and were unresponsive, intolerant, or contraindicated to NSAIDs and/or colchicine, and if on ULT, ULT was stable. Patients were randomized during an acute attack to single dose CAN 150 mg s.c. or TA 40 mg i.m. and were redosed "on demand" for each new attack. Patients completing the core studies were enrolled into blinded 12-week extension studies to further investigate on-demand use of CAN vs TA for new attacks. The subpopulation selected for this post-hoc analysis was (a) unable to use NSAIDs and colchicine due to contraindication, intolerance or lack of efficacy for these drugs, and (b) currently on ULT, or contraindication or previous failure of ULT, as determined by investigators. Subpopulation comprised 101 patients (51 CAN; 50 TA) out of 454 total. Results: Several co-morbidities, including hypertension (56%), obesity (56%), diabetes (18%), and ischemic heart disease (13%) were reported in 90% of this subpopulation. Pain intensity (VAS 100 mm scale) was comparable between CAN and TA treatment groups at baseline (least-square [LS] mean 74.6 and 74.4 mm, respectively). A significantly lower pain score was reported with CAN vs TA at 72 hours post dose (1st co-primary endpoint on baseline flare; LS mean, 23.5 vs 33.6 mm; difference _10.2 mm; 95% CI, _19.9, _0.4; P_0.0208 [1-sided]). CAN significantly reduced risk for their first new attacks by 61% vs TA (HR 0.39; 95% CI, 0.17-0.91, P_0.0151 [1-sided]) for the first 12 weeks (2nd co-primary endpoint), and by 61% vs TA (HR 0.39; 95% CI, 0.19-0.79, P_0.0047 [1-sided]) over 24 weeks. Serum urate levels increased for CAN vs TA with mean change from baseline reaching a maximum of _0.7 _ 2.0 vs _0.1 _ 1.8 mg/dL at 8 weeks, and _0.3 _ 2.0 vs _0.2 _ 1.4 mg/dL at end of study (all had GA attack at baseline). Adverse Events (AEs) were reported in 33 (66%) CAN and 24 (47.1%) TA patients. Infections and infestations were the most common AEs, reported in 10 (20%) and 5 (10%) patients treated with CAN and TA respectively. Incidence of SAEs was comparable between CAN (gastritis, gastroenteritis, chronic renal failure) and TA (aortic valve incompetence, cardiomyopathy, aortic stenosis, diarrohea, nausea, vomiting, bicuspid aortic valve) groups (2 [4.0%] vs 2 [3.9%]). Conclusion: CAN provided superior pain relief and reduced risk of new attack in highly-comorbid GA patients unable to use NSAIDs and colchicine, and who were currently on stable ULT or unable to use ULT. The safety profile in this post-hoc subpopulation was consistent with the overall _-RELIEVED and _-RELIEVED II population.

Intimate partner violence against pregnant women: the environment according to Levine's nursing theory

Abstract OBJECTIVE Analyzing the elements that compose the environment of pregnant women who have experienced intimate partner violence in the light of Levine's Nursing Theory. METHOD A qualitative, descriptive study conducted from September to January 2012, with nine pregnant women in a Municipal Health Center in Rio de Janeiro. The interviews were semi-structured and individual. The theoretical framework was based on Levine's Nursing Theory. RESULTS Thematic analysis evidenced the elements that composed the external environment, such as violence perpetrated by intimate partners before and during pregnancy, violence in childhood and adolescence, alcohol consumption and drug use by the partner, unemployment, low education and economic dependency, which affected health and posed risks to the pregnancy. CONCLUSION Violence perpetrated by an intimate partner was the main external factor that influenced the internal environment with repercussions on health. This theory represents a tool in nursing care which will aid in detecting cases and the fight against violence.

Risk reduction practices in men who have sex with men in Switzerland: serosorting, strategic positioning, and withdrawal before ejaculation.

The aim of this study was to identify predictors of intentional use of the HIV risk reduction practices of serosorting, strategic positioning, and withdrawal before ejaculation during unprotected anal intercourse (UAI) with casual partners. A cross-sectional survey pertaining to the Swiss HIV behavioral surveillance system, using an anonymous self-administered questionnaire, was conducted in 2007 in a self-selected sample of men having sex with other men (MSM). Analysis was restricted to participants with UAI with casual partner(s) (N = 410). Logistic regression was used to estimate factors associated with intentional use of serosorting, strategic positioning, and withdrawal before ejaculation. In the previous 12 months, 71% of participants reported having UAI with a casual partner of different or unknown HIV-status. Of these, 47% reported practicing withdrawal, 38% serosorting, and 25% strategic positioning. In the 319 participants with known HIV-status, serosorting was associated with frequent Internet use to find partners (OR = 2.32), STI (OR = 2.07), and HIV testing in the past 12 months (OR = 1.81). Strategic positioning was associated with HIV-status (OR = 0.13) and having UAI with a partner of different or unknown HIV-status (OR = 3.57). Withdrawal was more frequently practiced by HIV-negative participants or participants reporting high numbers of sexual partners (OR = 2.48) and having UAI with a partner of unknown or different serostatus (OR = 2.08). Risk reduction practices are widely used by MSM, each practice having its own specificities. Further research is needed to determine the contextual factors surrounding harm reduction practices, particularly the strategic or opportunistic nature of their use.

Source inference of exogenous gamma-hydroxybutyric acid (GHB) administered to humans by means of carbon isotopic ratio analysis: novel perspectives regarding forensic investigation and intelligence issues.

γ-Hydroxybutyric acid (GHB) is an endogenous short-chain fatty acid popular as a recreational drug due to sedative and euphoric effects, but also often implicated in drug-facilitated sexual assaults owing to disinhibition and amnesic properties. Whilst discrimination between endogenous and exogenous GHB as required in intoxication cases may be achieved by the determination of the carbon isotope content, such information has not yet been exploited to answer source inference questions of forensic investigation and intelligence interests. However, potential isotopic fractionation effects occurring through the whole metabolism of GHB may be a major concern in this regard. Thus, urine specimens from six healthy male volunteers who ingested prescription GHB sodium salt, marketed as Xyrem(®), were analysed by means of gas chromatography/combustion/isotope ratio mass spectrometry to assess this particular topic. A very narrow range of δ(13)C values, spreading from -24.810/00 to -25.060/00, was observed, whilst mean δ(13)C value of Xyrem(®) corresponded to -24.990/00. Since urine samples and prescription drug could not be distinguished by means of statistical analysis, carbon isotopic effects and subsequent influence on δ(13)C values through GHB metabolism as a whole could be ruled out. Thus, a link between GHB as a raw matrix and found in a biological fluid may be established, bringing relevant information regarding source inference evaluation. Therefore, this study supports a diversified scope of exploitation for stable isotopes characterized in biological matrices from investigations on intoxication cases to drug intelligence programmes.

Biologia, comportamento social e alocação sexual de Digelasinus diversipes (Kirby, 1882) (Hymenoptera, Argidae)

São apresentados os resultados de um estudo de dois anos sobre o Symphyta neotropical Digelasinus diversipes. Esta espécie é univoltina e comum na Estação Ecológica Jataí, uma reserva de Cerrado no Estado de São Paulo. As larvas alimentam-se gregariamente em Eugenia glazioviana (Myrtaceae) de novembro a abril. Associações entre grupos de alimentação foram freqüentes. Após o período de alimentação, as larvas congregam-se e comunalmente constróem uma massa de casulos (105 casulos ± 60DP; n = 25) aderida ao tronco da planta hospedeira, permanecendo em diapausa como prepupas até o início da estação chuvosa, em outubro. O pico populacional foi observado em dezembro, quando 62% (n = 2.967) dos adultos emergiram. Em condições experimentais, foram observadas emergências das 6:30 às 15:00 h, mas 73,5% (n = 223) dos adultos emergiram entre 9:00 e 12:00 h. Não foi observado, durante a emergência, sequenciamento sexual, mas em um agregado de casulos os machos podem emergir de 20 a 40 dias antes das fêmeas. Após a emergência os machos podem (1) dispersar-se (no início e final do período de emergência; outubro e novembro, janeiro e fevereiro, respectivamente) ou (2) permanecer sobre ou próximo ao agregado de casulos e copular com as fêmeas recém-emergidas (durante o pico de emergência, em dezembro). As cópulas duraram 4,28 minutos (± 3,4DP; n = 28). Ao longo do dia, os machos podem copular com diferentes fêmeas (1-8; n = 5); contudo, as fêmeas copularam apenas uma vez. Em média, as fêmeas emergem com 76 (± 21DP; n = 19) ovos maduros e todos eles são ovipositados de uma só vez sob uma única folha da planta hospedeira. A guarda dos ovos pelas fêmeas durou apenas 2 dias (n = 12) dos 30 necessários para sua incubação. O repertório de comportamentos da fêmea contra potenciais inimigos foi menor do que o observado em outras espécies de Symphyta. Aparentemente, a fêmea induz um necrosamento do tecido foliar que cobre os ovos. Isto formaria uma proteção rígida para os ovos durante sua incubação. Em D. diversipes, adultos de ambos os sexos não se alimentaram (condição controlada) e tiveram vida curta (5,2 dias ± 1,7DP; mínimo 1, máximo 11; n = 179). A razão sexual média foi 2,83 (± 0,014EP) em favor de fêmeas. Os principais fatores de mortalidade foram falhas no desenvolvimento, falta de alimento devido à intensa herbivoria e ataque de parasitóides. Parasitóides criados, Lymeon dieloceri (Costa Lima, 1937) (Ichneumonidae), Conura (Spilochalcis) sp. (Chalcididae) e Perilampus sp. (Perilampidae).

Geochemistry and stable isotope composition of fresh alkaline porphyry copper tailings: Implications on sources and mobility of elements during transport and early stages of deposition

Prevention of acid mine drainage (AMD) in sulfide-containing tailings requires the identification of the geochemical processes and element pathways in the early stages of tailing deposition. However, analyses of recently deposited tailings in active tailings impoundments are scarce because mineralogical changes occur near the detection limits of many assays. This study shows that a detailed geochemical study which includes stable isotopes of water (delta H-2, delta O-18), dissolved sulfates (delta S-34, delta O-18) and hydrochernical parameter (pH, Eh, DOC, major and trace elements) from tailings samples taken at different depths in rainy and dry seasons allows the understanding of weathering (oxidation, dissolution, sorption, and desorption), water and element pathways, and mixing processes in active tailings impoundments. Fresh alkaline tailings (pH 9.2-10.2) from the Cu-Mo porphyry deposit in El Teniente, Chile had low carbonate (0.8-1.1 Wt-% CaCO3 equivalent) and sulfide concentrations (0.8-1.3 wt.%, mainly as pyrite). In the alkaline tailings water, Mo and Cu (up to 3.9 mg/L Mo and 0.016 mg/L Cu) were mobile as MoO42- and Cu (OH)(2)(0). During the flotation, tailings water reached equilibrium with gypsum (up to 738 mg/L Ca and 1765 mg/ L SO4). The delta S-34 VS. delta O-18 covariations of dissolved sulfate (2.3 to 4.5% delta S-34 and 4.1 to 6.0 % delta O-18) revealed the sulfate sources: the dissolution of primary sulfates (12.0 to 13.2%. delta S-34, 7.4 to 10.9%.delta O-18) and oxidation of primary sulfides (-6.7 to 1.7%. delta S-34). Sedimented tailings in the tailings impoundment can be divided into three layers with different water sources, element pathways, and geochemical processes. The deeper sediments (> 1 m depth) were infiltrated by catchment water, which partly replaced the original tailings water, especially during the winter season. This may have resulted in the change from alkaline to near-neutral pH and towards lower concentrations of most dissolved elements. The neutral pH and high DOC (up to 99.4 mg/L C) of the catchment water mobilized Cu (up to 0.25 mg/L) due to formation of organic Cu complexes; and Zn (up to 130 mg/L) due to dissolution of Zn oxides and desorption). At I m depth, tailings pore water obtained during the winter season was chemically and isotopically similar to fresh tailings water (pH 9.8-10.6, 26.7-35.5 mg/L Cl, 2.3-6.0 mg/L Mo). During the summer, a vadose zone evolved locally and temporarily up to 1.2 m depth. resulting in a higher concentration of dissolved solids in the pore water due to evaporation. During periodical new deposition of fresh tailings, the geochemistry of the surface layer was geochemically similar to fresh tailings. In periods without deposition, sulfide oxidation was suggested by decreasing pH (7.7-9.5), enrichment of MoO42- and SO42-, and changes in the isotopic composition of dissolved sulfates. Further enrichment for Na, K, Cl, SO4, Mg, Cu, and Mo (up to 23.8 mg/L Mo) resulted from capillary transport towards the surface followed by evaporation and the precipitation of highly soluble efflorescent salts (e.g., mirabilite, syngenite) at the tailing surface during summer.

Sexual associations for two species of mutillid wasps (Hymenoptera, Mutillidae), with the description of a new species of Anomophotopsis

The sexes of Pseudometocha melanocephala (Perty, 1833) and of a new species of Anomophotopsis are associated based on mating pairs found in the field and also in laboratory mating trials. The previously unknown male of Pseudomethoca melanocephala (Perty, 1833) and both sexes of Anomophotopsis quinteroi Cambra, sp. nov., are described. We present the first distribution record of P. melanocephala from Argentina. Anecdotal data on their mating behavior are also discussed.

Comportamento sexual de Anastrepha sororcula Zucchi (Diptera, Tephritidae) em laboratório

Anastrepha sororcula Zucchi, 1979, é uma das espécies de mosca-das-frutas mais disseminadas no País, sendo considerada a praga-chave que causa os maiores danos à produção de goiaba (Psidium guajava L., 1758) no Brasil. Em vista da importância desta espécie no complexo de pragas naturais da fruticultura brasileira e, em face à escassez de dados sobre sua biologia e comportamento, este trabalho teve por objetivo obter informações sobre a idade de maturação sexual de A. sororcula em laboratório e descrever seu comportamento reprodutivo. Os machos atingiram a maturidade sexual entre 7 e 18 dias após a emergência, com a maioria dos indivíduos tornando-se sexualmente maduros entre 10 e 13 dias de idade. Exibiram comportamento de sinalização às fêmeas, caracterizado pela distensão da região pleural do abdome, formando uma pequena bolsa de cada lado e, eversão de uma diminuta bolsa membranosa de cutícula retal que circunda a área anal. Durante este processo, os machos realizaram rápidos movimentos de vibração das asas, produzindo sinais audíveis. Uma gotícula foi liberada da região anal durante os movimentos de vibração alar. Após a atração das fêmeas, os machos realizaram uma série de movimentos elaborados de cortejo. As fêmeas alcançaram a maturação sexual entre 14 e 24 dias da emergência, com a maioria tornando-se sexualmente madura aos 19 dias de idade. A exibição diária das atividades sexuais foi confinada quase que exclusivamente ao período das 16:00-17:30h. A. sororcula apresentou um acentuado padrão de protandria.

Traitement des fractures de l'enfant par enclouage centro-médullaire élastique stable (ECMES) [Treatment of pediatric fractures by intramedullary stable elastic pinning]

During the past decade several new techniques for the treatment of children's fractures respecting the specificity of the growing bone have been described. The goal of all these techniques was to mechanically stabilise the fracture however to preserve a certain instability of the fracture gap itself inducing early callus formation and subsequent consolidation. The dynamic external fixation as well as the elastic stable intramedullary pinning have become accepted means in the treatment of long bone fractures in the paediatric age group. We report our experience of the last seven years with the intramedullary pinning of 105 fractures. Eighty-four were fractures of the femur, 9 of the humerus, 8 of the forearm, and a further 4 of the tibial shaft. The intramedullary elastic pinning represents a simple technique which supports or even enhances the natural process of fracture healing of the growing bone. The method is not very invasive, is cost effective, and allows short hospitalisation. Early physical activity is guaranteed due to early consolidation of the fracture. Complications are rare and the final orthopedic and cosmetic outcome is excellent.

Diagnostic de la maladie coronarienne stable par FFR non invasive, mythe ou réalité [Diagnosis of stable coronary artery disease with non-invasive FFR: myth or reality?].

Decision to revascularize a patient with stable coronary artery disease should be based on the detection of myocardial ischemia. If this decision can be straightforward with significant stenosis or in non-significant stenosis, the decision with intermediate stenosis is far more difficult and require invasive measures of functional impact of coronary stenosis on maximal blood (flow fractional flow reserve=FFR). A recent computer based method has been developed and is able to measure FFR with data acquired during a standard coronary CT-scan (FFRcT). Two recent clinical studies (DeFACTO and DISCOVER-FLOW) show that diagnostic performance of FFRcT was associated with improved diagnostic accuracy versus standard coronary CT-scan for the detection of myocardial ischemia although FFRcT need further development.

Duplo Padrão Sexual e Conhecimento das Doenças Sexualmente Transmissíveis nos Estudantes Africanos em Braga

A modificação do comportamento de risco e o estudo dos factores psicossociais associados a esses comportamentos têm vindo a assumir um papel de grande importância no domínio da prevenção das doenças sexualmente transmissíveis. Contudo, têm sido vários os factores, nomeadamente de carácter social e psicossocial relacionada com as práticas de comportamentos sexuais de risco. São disso exemplo as normas sociais que ditam o comportamento sexual mais indicado para homens e para as mulheres (duplo padrão sexual) e, por outro lado, os factores relacionados com a adopção de comportamentos e estratégias de protecção contra as DST`s e o HIV/SIDA. Este estudo teve como objectivo principal verificar a relação entre o duplo padrão sexual e o conhecimento das DST`s. Ou seja, pretende-se ver como a influência do duplo padrão e dos estereótipos sociais influenciam o comportamento e prática sexual, os conhecimentos, atitudes e crenças dos jovens africanos (PALOP) estudantes da Universidade do Minho e da Universidade Católica Portuguesa de Braga. A amostra foi constituída por 107 participantes, predominantemente do sexo feminino (n=64) e masculino (n=43) com a idade compreendida entre os 17 e os 30 anos. Este estudo centrou a atenção numa população de jovens adultos com características específicas: “estudantes africanos”. Os instrumentos utilizados foram a Escala do Duplo Padrão Sexual, traduzido e adaptado a população portuguesa por Nogueira, 2008 e o Questionário do Conhecimento das Doenças Sexualmente Transmissíveis adaptado a população portuguesa por Cruz e Nogueira, 2007. Os resultados obtidos apontaram para: a) a existência de um duplo padrão sexual tradicional; b) a não existência de relações significativas entre o grau de conhecimentos e as outras variáveis psicossociais; e c) um baixo nível do conhecimento das DST`s. Este estudo parece revelar-se de uma importância fundamental para a intervenção e prevenção das DST`s em particular do HIV/SIDA. Também parece evidenciar a potencial ineficácia de programas de prevenção das DST`s centrados único e exclusivamente na transmissão de conhecimentos, como sendo um único indicador da eficácia dos programas de prevenção e mudanças de atitudes e comportamentos.
