Les routes d’invasion du criocère du lis (Lilioceris lilii) en Amérique du Nord

Le criocère du lis, Lilioceris lilii (Coleoptera : Chrysomelidae), un ravageur de lis et de fritillaires d’origine eurasienne, a été observé pour la première fois en Amérique du Nord en 1943 sur l’Ile de Montréal au Canada. Après y avoir été confiné pendant environ 25 années, ce coléoptère a par la suite progressé rapidement sur le territoire nord-américain. Actuellement, on l’observe dans huit provinces canadiennes et huit états américains. Cette étude a investigué les routes d’invasion utilisées par le criocère du lis au Canada et aux États- Unis avec l’aide de marqueurs génétiques AFLP. Pour ce faire, 516 individus parmi 34 sites en Amérique du Nord et en Europe ont été échantillonnés et analysés. Le premier objectif était de déterminer, en analysant la structure génétique des populations nord-américains, s’il y avait eu une ou plusieurs introductions en provenance d’Europe. Le deuxième objectif était d’identifier l’origine de la ou des populations introduites en Amérique du Nord. Finalement, le troisième objectif consistait à proposer un scénario d’invasion de L. lilii en Amérique du Nord basé sur les données de première mention et de structure génétique des populations échantillonnées. Les résultats démontrent une signature génétique distincte entre les criocères du lis du Canada et ceux des États-Unis, suggérant ainsi deux sources d’introductions indépendantes en Amérique du Nord, soit une première introduction à Montréal, Québec, dans les années 1940 et une seconde aux États-Unis au début des années 1990 à Cambridge, Massachusetts. De plus, les deux populations nord-américaines semblent provenir de différentes régions du nord de l’Europe, ce qui est conséquent avec le scénario suggérant deux sources d’introductions indépendantes. Chacune des populations aurait par la suite progressé respectivement dans leur pays d’introduction selon une dispersion de type stratifiée. En effet, la progression continue de L. lilii dans certaines régions suggère une dispersion naturelle de l’espèce sur le territoire nord-américain, alors que la progression rapide sur de longues distances semble être causée par le transport anthropique de lis contaminés.

Eficacia de la estimulación magnética transcraneal en la disminución de severidad en el trastorno depresivo mayor en monoterapia y coadyuvante comparado con tratamientos farmacológicos. Revisión sistemática y meta-análisis

Resumen Introducción Una posible opción de tratamiento para el manejo del trastorno depresivo mayor (TDM) es la estimulación magnética transcraneal (EMT) que ha mostrado propiedades antidepresivas superiores al placebo con un buen perfil de seguridad. El objetivo del presente trabajo es determinar la reducción en la severidad del TDM y la proporción de eventos adversos (EA) en pacientes con TDM refractario y no refractario, posterior al uso de EMT administrada en monoterapia o tratamiento coadyuvante comparado con terapia farmacológica. Metodología Se planteó una pregunta PICOT de la cual se realizó una búsqueda sistemática de estudios clínicos en las bases de datos Medline, EMBASE y Cochrane. Dos investigadores en forma independiente realizaron la selección de artículos, evaluación de calidad con la herramienta de la colaboración Cochrane y extracción de datos. Se extrajeron datos de eficacia como tasa de respuesta, porcentaje de remisión, calidad de vida, diminución sintomática del trastorno depresivo mayor en la escala de Hamilton y capacidad funcional. Igualmente, proporción de pacientes con EA. Se realizó un meta-análisis de estas variables teniendo en cuenta la heterogeneidad. Resultados La presente revisión sistemática incluyó 26 estudios clínicos aleatorizados de baja calidad metodológica mostrando que la EMT presentó una eficacia superior cuando es usada como coadyuvante a las terapias con que venían siendo tratados los pacientes con TDM refractario y no refractario en los desenlaces de tasa de respuesta y porcentaje de remisión. En el caso de intervenciones farmacológicas específicas, la EMT presento eficacia similar, tanto en terapia coadyuvante como en monoterapia comparado con las intervenciones farmacológicas. En cuanto a seguridad, la EMT presenta un buen perfil de seguridad debido a que en todos los escenarios estudiados los EA fueron no serios y baja frecuencia Conclusiones La evidencia disponible sugiere que la EMT mostró ser efectivo y seguro para el manejo del TDM refractario y no refractario. Sin embargo, la evidencia es débil por lo tanto se necesita mayor investigación clínica que soporte su uso.

Growth of the lava dome and extrusion rates at Soufrière Hills Volcano, Montserrat, West Indies: 2005–2008

The third episode of lava dome growth at Soufrière Hills Volcano began 1 August 2005 and ended 20 April 2007. Volumes of the dome and talus produced were measured using a photo-based method with a calibrated camera for increased accuracy. The total dense rock equivalent (DRE) volume of extruded andesite magma (306 ± 51 Mm3) was similar within error to that produced in the earlier episodes but the average extrusion rate was 5.6 ± 0.9 m3s−1 (DRE), higher than the previous episodes. Extrusion rates varied in a pulsatory manner from <0.5 m3s−1 to ∼20 m3s−1. On 18 May 2006, the lava dome had reached a volume of 85 Mm3 DRE and it was removed in its entirety during a massive dome collapse on 20 May 2006. Extrusion began again almost immediately and built a dome of 170 Mm3 DRE with a summit height 1047 m above sea level by 4 April 2007. There were few moderate-sized dome collapses (1–10 Mm3) during this extrusive episode in contrast to the first episode of dome growth in 1995–8 when they were numerous. The first and third episodes of dome growth showed a similar pattern of low (<0.5 m3s−1) but increasing magma flux during the early stages, with steady high flux after extrusion of ∼25 Mm3

The central European floods of August 2002: Part 2 - Synoptic causes and considerations with respect to climatic change

In the first part of this paper (Ulbrich et al. 2003), we gave a description of the August 2002 rainfall events and the resultant floods, in particular of the flood wave of the River Elbe. The extreme precipitation sums observed in the first half of the month were primarily associated with two rainfall episodes. The first episode occurred on 6/7 August 2002. The main rainfall area was situated over Lower Austria, the south-western part of the Czech Republic and south-eastern Germany. A severe flash flood was produced in the Lower Austrian Waldviertel (`forest quarter’ ). The second episode on 11± 13 August 2002 most severely affected the Erz Mountains and western parts of the Czech Republic. During this second episode 312mm of rain was recorded between 0600GMT on 12 August and 0600GMT on 13 August at the Zinnwald weather station in the ErzMountains, which is a new 24-hour record for Germany. The flash floods resulting from this rainfall episode and the subsequent Elbe flood produced the most expensive weatherrelated catastrophe in Europe in recent decades. In this part of the paper we discuss the meteorological conditions and physical mechanisms leading to the two main events. Similarities to the conditions that led to the recent summer floods of the River Oder in 1997 and the River Vistula in 2001 will be shown. This will lead us to a consideration of trends in extreme rainfall over Europe which are found in numerical simulations of anthropogenic climate change.

Estudo da resposta inflamatória em lactentes com sibilância : análise de IL-10 e celularidade no aspirado nasofaríngeo

Episódios de sibilância secundários a infecções respiratórias virais são comuns nos primeiros anos de vida. Contudo, sua patogênese e relação com o posterior surgimento de asma permanecem ainda pouco esclarecidos. Com o objetivo de analisar a resposta celular e da IL-10 em lactentes com sibilância, foram analisadas amostras de aspirado nasofaríngeo de 71 lactentes. Os pacientes foram classificados em três grupos: primeiro episódio de sibilância (n=36), sibilância recorrente (n=18) e infecção de vias aéreas superiores (n=17). O exame citológico da secreção nasofaríngea demonstrou uma predominância de neutrófilos em todos os grupos. Não foi evidenciada a presença de eosinófilos na secreção nasofaríngea de nenhum paciente, exceto em um caso do grupo de sibilância recorrente, cujo percentual dessas células foi de 1%. Foram encontrados níveis de IL-10 significativamente aumentados no aspirado nasofaríngeo do grupo com primeiro episódio de sibilância, quando comparados ao grupo de infecção de vias aéreas superiores (p=0,017). Não foi encontrada correlação significativa entre os níveis de IL-10 em secreção nasofaríngea e gravidade do episódio de sibilância. Conclui-se que os neutrófilos são as células que predominam na resposta inflamatória em lactentes com sibilância secundária à infecção respiratória viral e que a IL-10 pode ser uma citocina com participação importante na predisposição à doença obstrutiva brônquica do lactente.

Caracterização comportamental endócrina das fases ontogenéticas de sagüi comum (Callithrix jacchus)

The use of animal models in biomedical research is ever increasing. Models that use primates might also have advantages in terms of low maintenance costs and availability of biological knowledge, thereby favoring their use in different experimental protocols. Many current stress studies use animal models at different developmental stages since biological response differs during ontogeny. The aims of this study were to perform a detailed characterization of the developmental stages of common marmosets (Callithrix jacchus), a very important animal model used in biomedical research. Ten subjects, 6 females and 4 males, were followed from birth to initial adult age (16 months). Behavioral and fecal collection for measurement of adrenal (cortisol) and sex (progesterone, estradiol and androgens) hormones took place twice a week during the first month of life and once a week for the remainder of the study. Behavior was observed for 30 minutes in the morning (0700-09:00h) and afternoon (12:00-14:00h). Behavioral profile showed changes during ontogeny, characterizing the 4 developmental stages and the respective phases proposed by Leão et al (2009).. Differentiation of developmental stages was considered using the onset, end, change and stabilization of the behavioral profile parental care (weaning and carrying), ingestion (solid food), affiliation (social grooming) and autogrooming, agonism (scent marking and piloerection) and play behavior and endocrine profile. Infant weaning and carrying terminated within the infantile stage and the peak of solid food ingestion was recorded in the infantile III phase. Receiving grooming was recorded earlier than grooming performed by the infant and autogrooming. The first episode of scent marking was recorded in the 4th week and it was the least variable behavior, in terms of its onset, which, in almost all animals, was between the 5th and 7th week of life. Solitary play and play with the twin started around the 7th week and play with other members of the group started 8 weeks later. Sex hormone secretion started to differ from basal levels between the 21st and 23rd week of life, in males and females, suggesting that puberty occurs simultaneously in both sexes. Basal cortisol, even at an early age, was higher in females than in males. However, cortisol was not correlated with the juvenile stage, as expected, since this stage corresponds to the transition between infancy and adult age and most behaviors are intensified by this time. The behavioral and endocrine profile of subadult animals did not differ from that of the adults. These results provide more detailed parameters for the developmental process of C. jacchus and open new perspectives for the use of experimental approaches focused on the intermediate ontogenetic phases of this species

Venous ulcer: clinical characteristics and risk factors

BackgroundLower limb venous ulceration ranks among the 10 most common medical problems in Western countries and has significant socioeconomic impact. The aim of this study was to identify the risk factors for unhealed, recurrent, and large ulcers and to characterize patients with active or recently healed venous ulcers.MethodsWe identified 97 patients and assessed 103 ulcerated limbs in 90 patients. All patients underwent clinical examination, arterial and venous system evaluation, ankle-brachial index determination, and ultrasound of the affected limb. Clinical characteristics included age, gender, race, ulcer duration, time since first episode, history of recurrence, localization of ulcer, ulcer area, eczema, ochre dermatitis, lipodermatosclerosis, pain, body mass index, and medical history data. Risk factors were identified by univariate analysis and estimated odds ratios.ResultsWe assessed 90 patients (103 limbs) with active or healed venous leg ulcers, of whom 84.4% were Caucasian and 68.9% were female. Mean age was 56.0 +/- 13.3 years. Ulcers had remained unhealed for < 1 year in 40.7%. Lipodermatosclerosis, lower limb hyperpigmentation, edema, and eczema were seen in 96.7%, 95.6%, 94.4%, and 51.1% of patients, respectively. Pain was a frequent symptom in 74.4%. Body mass index was assessed in 85 patients: 30.6% were slightly, 36.5% moderately, and 7% severely obese. Patient age > 60 years (odds ratio [OR] 4.0), extensive lipodermatosclerosis (OR 8.7), and previous history of ulceration (OR 19.9) were risk factors for unhealed ulcers. Time since first ulcer episode >= 2 years (OR 29.2) and incompetence of venous systems (OR 1.6) were risk factors for recurrence.ConclusionsLongstanding and large ulcers and recurrences are the main problems encountered by venous ulcer patients. Severe lipodermatosclerosis, previous ulcer history, and time since first ulcer episode >= 2 years are significant risk factors.

Evolução termocronológica do sistema de falhas Senador Pompeu-CE

The region of the Senador Pompeu Shear Zone (SPSZ), in the North Tectonic Domain of the Borborema Province (BP), has its recent history associated with to South Atlantic Ocean formation event at the Jurassic. A lot of geologics models have discussed about crustal axis elevation in local scale and large scale (Borborema Province), relative to importants regionals tectonics directions of it. The identification and the relationship among this surfaces, stepped in many topographyc levels by tectonics mecanisms, is dificult because of the erosion process on it. Over there, sedimentary deposits is complex and it has not biostratigraphyc record in continental deposits. The analysis metodology on apatita fission-track, in the region of the SPSZ, purpose the more knowledge about morphotectonics mecanisms of the area and the impruvement of its morphotectonics models. For this, it was moleled the age and thermal history of the 11 apatites samples collected on both sides of this shear zone, taking relationships among other results of the thermochronology studies in the BP. Based on the thermal studies in this search, the region of the BP developed on two distint cooling events, separated for one period of relative stabilited. The first episode occur between 130 and 90 M.y., has been began when the samples cross the 120°C isoterm for last time and fineshed at 70°C. The second moment of the cooling process was began about 30 M.y., when the temperature was 90°C, from this to the equlibrium with present surface temperature at 30°C. Some evidences indicated a relacionship between thermal episodes and uplift events of the regional relief. The fundaments of the interpretation was based mainly on comparatives studies among results of the thermochronology analysis and geologics studies about BP. Nóbrega et al.(2005), e.g., on studies about the Portalegre Shear Zone, got similar results on SPSZ, with some details relative to local tectonic activity. Morais Neto et al. (2000) interpreted two importants cooling events in the BP based on their regional studies, that can be associated to regional uplift events. When Assine (1992) studied the stratigraphyc sequences of the Araripe Basin, in the south of Ceará state, conclude that the abrupt return to continentals condictions from the last sedimentar sequency (albiano-cenomaniane) indicate a regional uplift of the NE region of the Brazil at the 100 M.y., in the Albiano Intermediate/Superior. This ages are compatible to termal model of the SPSZ. This two periods of the thermal history of the BP are completely registered in the apatites samples just one age groups of the fission-track, that it is the most ancient age groups. This one suggest it has happened in response to heating before 75 M.y and it has erased the last report of the first moment relief evolution of the BP. The NNE-SSW and E-W structure reativation can have created ideal condictions for heating and local elevations of the geothermal gradients. The equilibrium between the apatites temperatures of this groups and the regionais temperatures took place about 50 M.y., when the samples of the two ages groups had a simillar evolution to present surfaces temperatures

Secretion of middle ear in infants - Occurrence, recurrence and related factors

Objective: The present study aimed at evaluating the occurrence and recurrence of middle ear effusion and possible associated factors in the first two years of life of 190 newborns and infants, participants in the interdisciplinary prevention, detection, and intervention program at the Clínica de Educação para Saúde of Universidade do Sagrado Coração, Methods: Newborns and infants were monthly submitted to anamneses, otoscopy, behavioral hearing assessment using sound instruments and pure tones (pediatric audiometry) and tympanometry. Results: The results revealed that 68.4% of infants presented one or more episodes of middle ear effusion during their two first years, with more recurrence among males. Peak occurrence was between four and 12 months of age and, the earlier the first episode, the higher the probability of recurrence. Greatest incidence was during May and August. It was found that, of the variables investigated, the period of exclusive breastfeeding actuated as a protector factor. With respect of risk factors, it was observed that passive smoking, gastro-esophageal reflux and respiratory allergy were related with the recurrences of effusion. Conclusion: Findings revealed the importance of periodic auditory follow-up for infants during their first two years of life, considered to be the critical period of auditory system maturation, during which sensory deprivation can be responsible for damage to the development of speech, language and other auditory abilities.

Descrição de outras doenças sexualmente transmissíveis em pessoas infectadas pelo vírus da imunodeficiência humana do tipo 1

Noventa pacientes soropositivos para o HIV-1 foram estudados, visando-se a descrição de manifestações clínicas e de marcadores de outras doenças sexualmente transmissíveis, assim como de fatores demográficos e comportamentais que possam estar relacionados com a infecção pelo HIV-1 e em pacientes com SIDA/AIDS. A maioria dos entrevistados (83,3%) foi do sexo masculino, apresentou a média de idade 31,4 anos (variando entre 18 e 60 anos) e a distribuição da renda familiar mensal mostrou que 79,5% tinham um ganho inferior a cinco salários mínimos. Pelos menos um tipo de droga, foi consumido por 51,1%, sendo que 20.7% usaram droga não medicamentosa de uso injetável. Destes, 94,4% referiram antecedentes de doenças sexualmente transmissíveis. A observação dos hábitos sexuais revelou que 41,6% eram bissexuais, 38,2% heterossexuais e 20,2% eram homossexuais. Cerca de 51,1% dos bissexuais usaram drogas injetáveis e todos referiram a prática de sexo anal e foram positivos para a presença de anticorpos para Chlamydia. A média de idade da primeira relação sexual com penetração foi de 14.7 anos, enquanto que a média de idade em que ocorreu a primeira doença sexualmente transmissível foi de 20.6 anos. A quase totalidade (95,5%) dos entrevistados tiveram múltiplos parceiros sexuais, antes do conhecimento da soropositividade para o HIV-1. Dentre os 90 soropositivos, 73,3% referiram antecedentes de doenças sexualmente transmissíveis. Destes, 82,2% referiram a presença de secreção uretraI, de sífilis e de herpes simples. No momento da avaliação, 36,6% (33/90) apresentaram secreção uretral, anal e/ou vaginal, lesão genital, anal, perianal e/ou adenopatia inguinal, assim discriminado: Secreção (51,1%), vesículas (18,1%), lesão verrucosa (18,1%), Adenopatias iguinais ( 18,1% ), úlceras ( 12,1 %) e pápulas (6% ). A reação do VDRL foi positiva em 13,7% (11/80), sendo que neste grupo, 90,9% referiram a prática do sexo anal e 81,8% revelaram antecedentes de DST. Cerca de 96,4% (81/84) apresentaram anticorpos para Chlamydia, sendo que 81,8% revelaram a prática do sexo anal e 72,8% relataram antecedentes de DST .

Eficácia e segurança de uma vacina oral de rotavírus humano atenuado contra gastroenterite grave por rotavírus, durante os primeiros dois anos de vida em crianças em Belém, Pará, Brasil

Os rotavírus se constituem nos principais agentes causadores de gastroenterite grave entre crianças com idades inferiores a 5 anos, tanto nos países desenvolvidos quanto naqueles em desenvolvimento, com pico de incidência entre 6 e 24 meses de vida. Em termos globais, estima-se que pelo menos 500.000 óbitos por ano se associem a esse enteropatógeno. Um extenso ensaio clínico de fase 111, randomizado na proporção de 1 :1, controlado por placebo e duplo-cego, envolvendo 11 países da América Latina e a Finlândia se levou a efeito objetivando-se avaliar a eficácia e segurança de uma vacina atenuada, de origem humana, contra rotavírus, denominada RIX4414. Na totalidade, recrutaram-se mais de 63.000 crianças. Em Belém, Pará, tais estudos envolveram 3.218 indivíduos aos quais se administraram duas doses de vacina ou placebo, no segundo e quarto meses de idade. Desse total avaliou-se um subgrupo de 653 crianças quanto à eficácia da vacina, com acompanhamento ao longo de 1 a 2 anos, quando se registraram 37 episódios de GE grave por rotavírus, 75,6% (28/37) dos quais no grupo placebo e 24,3% (9/37) entre os vacinados, daí se inferindo eficácia da vacina de 68,8% (IC95% 32.0-87,0) nos primeiros dois anos de vida. No que se refere à intensidade desses episódios, notou-se maior eficácia contra os classificados como muito graves (escore de Ruuska & Vesikari ≥ 15), alcançando níveis de 83% (IC95% 22-96). No grupo placebo observou-se risco cumulativo, quanto ao desenvolvimento de gastroenterite grave por rotavírus, 4 vezes superior em relação ao vacinado. Quanto aos sorotipos de rotavírus G1 e não-G1, evidenciou-se proteção de 51 % (IC95% -30 - 81) e 82% (IC95% 37-95), respectivamente, denotando-se proteção tanto homotípica quanto heterotípica. De particular relevância se constituiu a proteção frente ao G9 [93% (IC95% 47-99)], dado o caráter emergente global desse sorotipo, além do seu potencial quanto a desencadear quadros diarréicos rotineiramente mais graves. A eficácia da vacina contra episódios de GE de qualquer etiologia alcançou 35,3% (IC95% 11,6-52,9), do que se depreende o expressivo impacto em potencial da vacinação contra rotavírus em termos de saúde pública. No que se refere à segurança desse imunizante, não se observaram diferenças significativas do ponto de vista estatístico, entre os grupos vacina e placebo, no que concerne à ocorrência de eventos adversos graves. Não se registrou qualquer caso de intussuscepção entre os sujeitos participantes, mercê de extensiva vigilância ativa nos hospitais de referência. Os resultados encontrados nesse estudo corroboram os já descritos em ensaios multicêntricos como um todo, em vários continentes, consolidando os indicadores quanto à eficácia e segurança da vacina RIX4414 quando administrada em duas doses a crianças saudáveis.

Avaliação da terapêutica da malária por Plasmodium vivax: perfil cinético da cloroquina e primaquina

Os relatos crescentes da resistência aos antimaláricos no tratamento da malária vivax direcionam a busca de novas estratégias de aperfeiçoamento do tratamento e controle da doença e ao se considerar a ausência de dados referentes a eficácia da associação cloroquina e primaquina e seus respectivos perfis cinéticos em pacientes com malária vivax no estado do Pará, este estudo objetivou avaliar as características epidemiológicas, a resposta terapêutica e as funções renal e hepática de 40 pacientes com malária vivax atendidos no Programa de Ensaios Clínicos em Malária do Instituto Evandro Chagas (Belém/Pará) no período 2008 a 2010. Houve predomínio do gênero masculino (67,5%), a faixa etária de maior incidência foi 34-42 anos (30%), as ocupações principais foram maritimos e vendedores; a maioria (85%) residente em Belém-PA; os primoinfectados representaram 42,5%. A parasitemia inicial média foi 4.485,7 ± 6.732,7 parasitos/mm3, sendo considerada baixa em 95% e média em 5% dos casos. A anemia esteve presente em 60% dos casos com faixa estária predominante entre 23 a 60 anos; 57,5% apresentaram os demais índices hematimétricos foram normais em ambos os gêneros. Os parâmetros bioquímicos foram similares nos pacientes primoinfectados e recorrentes; O perfil cinético da cloroquina demonstrou pico de concentração plasmática de1.102,15 ± 313,52 ng/mL; em D30 foram D30 foram de 98,6 ± 35,88. Os teores médios de primaquina em D2, D7 e D14 foram de 210,2 ng/mL, 345,0 ng/mL e 91,7 ng/mL, respectivamente. O seguimento clínico e laboratorial dos pacientes não detectou recidiva da infecção após o seguimento de 28 dias, e não foram evidenciadas sintomatologia clínica adicional, o que aliado ao tempo médio de clareamento da parasitemia de 80±32 horas indicam que o esquema terapêutico utilizado foi eficaz com taxa de cura de 100%, bem como a qualidade das medidas de orientação, esclarecimento e seguimento do serviço de saúde nos quais os pacientes foram diagnosticados e tratados.
