During a research project aimed at the study of the Culicinae fauna of Gabon and carried out in the National Park of La Lopé, we captured an unknown sandfly male specimen (genus Phlebotomus) by CDC miniature light trap belonging to a new species for Science. Furthermore, the originality of his genitalia does not allow us to include this species in one of the existing subgenus, thus in this paper we propose the creation of a new subgenus, as Phlebotomus (Legeromyia) multihamatus sp. nov., subg. nov. described from the National Park of La Lopé, through one male captured with CDC miniature light trap. A new species and a new subgenus of sandfly is characterised by a short style with three spines, a paramere wearing a basal hook as well as a basal pouch and the absence of basal lobe on the coxite. The originality of the genitalia of the male gives way to discussion about potential primary homologies between P. multihamatus sp. nov. and Phlebotomus (Abonnencius) fortunatarum, Phlebotomus (Anaphlebotomus) stantoni and Phlebotomus (Euphlebotomus) argentipes, which should be verified for future studies. The discovery of this new species in Gabon must encourage the study of sandflies in this country.

Aiming to identify new sources of bioactive secondary metabolites, we isolated 82 endophytic fungi from stems and barks of the native Brazilian tree Caesalpinia echinata Lam. (Fabaceae). We tested their ethyl acetate extracts in several in vitro assays. The organic extracts from three isolates showed antibacterial activity against Staphylococcus aureus and Escherichia coli [minimal inhibitory concentration (MIC) 32-64 μg/mL]. One isolate inhibited the growth of Salmonella typhimurium (MIC 64 μg/mL) and two isolates inhibited the growth of Klebsiella oxytoca (MIC 64 μg/mL), Candida albicans and Candida tropicalis (MIC 64-128 μg/mL). Fourteen extracts at a concentration of 20 μg/mL showed antitumour activities against human breast cancer and human renal cancer cells, while two isolates showed anti-tumour activities against human melanoma cancer cells. Six extracts were able to reduce the proliferation of human peripheral blood mononuclear cells, indicating some degree of selective toxicity. Four isolates were able to inhibit Leishmania (Leishmania) amazonensis and one isolate inhibited Trypanosoma cruzi by at least 40% at 20 μg/mL. The trypanocidal extract obtained from Fusarium sp. [KF611679] culture was subjected to bioguided fractionation, which revealed beauvericin as the compound responsible for the observed toxicity of Fusarium sp. to T. cruzi. This depsipeptide showed a half maximal inhibitory concentration of 1.9 μg/mL (2.43 μM) in a T. cruzi cellular culture assay.

O presente trabalho tem como objetivo levantar o número de pacientes atendidas no Setor de Urgências Psiquiátricas (SUP) e ClÃnica Obstétrica do Hospital das ClÃnicas (COHC) da FMRP-USP, com o diagnóstico 648.4 (Transtornos Mentais na Gravidez, Parto e Puerpério), conforme CID-9, no perÃodo de 1988 a 1993. Solicitou-se um registro ao hospital, contendo informações sobre os atendimentos destes serviços. A população constitui-se de mulheres entre 15 e 29 anos cujos transtornos apresentados incluÃram distúrbios psicóticos, quadros depressivos com ou sem tentativas de suicÃdio e transtornos mentais não especificados. Alguns desses distúrbios apresentaram-se em comorbidade com outros diagnósticos. Os resultados evidenciaram a necessidade do enfermeiro estar atento à s manifestações sugestivas dos mesmos, bem como ajudar na busca de meios que facilitem a identificação de mulheres com alto risco.

Utilizando a técnica de Tábuas de Vida de Seguimento o presente estudo estimou a sobrevida de pacientes submetidos à hemodiálise, segundo grupo etário, de 1997 a 2000, em Ribeirão Preto-SP A partir das probabilidades de sobrevivência estimou também, os gastos por paciente que inicie o tratamento. Cerca de 60% dos pacientes seguidos continuavam vivos ao final dos quatros anos de estudo, apontando para uma sobrevivência elevada. Os resultados mostram ainda que o crescimento dos gastos com hemodiálise deve-se ao aumento da sobrevida e não especificamente a uma ampliação da demanda pela terapia.

A estratégia de Saúde da FamÃlia apresenta-se como uma alternativa de superação do paradigma dominante no campo da saúde. Este trabalho teve como objetivo identificar o processo de trabalho das enfermeiras no Programa Saúde da FamÃlia (PSF) no municÃpio de MarÃlia, SP. A metodologia utilizada baseou-se nos pressupostos da Teoria de Intervenção Práxica em Enfermagem em Saúde Coletiva proposto por Egry (1996). Foram sujeitos do estudo a totalidade de enfermeiras que atuavam no PSF do municÃpio de MarÃlia, no ano de 2001. Os dados foram coletados por meio de entrevista semi-estruturada e de observação direta do trabalho da enfermeira. Os resultados apontaram que as enfermeiras do PSF são jovens e possuem pouca experiência de trabalho em atenção básica. O processo de trabalho, desenvolvido por estas profissionais, toma como objeto o corpo individual, têm por finalidade os perfis de desgaste dos grupos sociais e utilizam meios e instrumentos tradicionais da saúde pública.

O primeiro contato do doente de tuberculose (TB) com o sistema de saúde se dá na porta de entrada, e é fundamental para o acesso ao diagnóstico. Objetivou-se identificar e analisar a porta de entrada no sistema de saúde de Ribeirão Preto para o diagnóstico da TB. Baseou-se em um instrumento do Primary Care Assessment Tool, adaptado para a TB no Brasil. Realizou-se entrevista estruturada com 100 doentes de TB diagnosticados entre Junho de 2006 e Julho de 2007. Destes, 61% chegaram ao local de diagnóstico por encaminhamento e apenas 29% se apresentaram espontaneamente; 66% procuraram por serviços de atenção primária, 34% por serviços de nÃvel secundário e terciário. Ademais, 89% foram diagnosticados em serviços públicos e destes, 44% foram diagnosticados nos pronto-atendimentos. Além disso, 88% foram diagnosticados fora de sua área de abrangência. Apesar dos doentes terem procurado atendimento na atenção primária e mais próximo de suas residências, o diagnóstico se deu na atenção secundária e terciária.

Recently, genetic evidence supported the existence of a new species of the genus Pollicipes from the Cape Verde Islands, previously considered a population of P. pollicipes. However, P. pollicipes was not sampled at its southern limit of distribution (Dakar, Senegal), which is geographically separated from the Cape Verde Islands by about 500 km. Herein we describe Pollicipes caboverdensis sp. nov. from the Cape Verde Islands and compare its morphology with the other three species of Pollicipes: P. pollicipes, P. elegans and P. polymerus. Pollicipes pollicipes was sampled at both the middle (Portugal) and southern limit (Dakar, Senegal) of its geographical distribution. The genetic divergence among and within these two regions and Cape Verde was calculated through the analysis of partial mtDNA CO1 gene sequences. Pollicipes caboverdensis sp. nov. has a single whorl of capitular plates below the subrostrum, peduncular scales pointing up toward the capitulum and multi-articulate caudal appendages (all characters shared with P. pollicipesand P. elegans), reddish-orange capitular plates (large specimens), a single rostral median latus between the median latus and the rostrolatus (both characters shared with P. elegans), and uniquely possesses peduncular scales that are approximately the same width as height. The genetic distance between the Cape Verde population and the Senegal and Portugal populations is 13–14%, whilst between Senegal and Portugal it is < 1%.

Objectives: To determine psychometric properties of the Functional Assessment of Chronic Illness Therapy-Spiritual well-being (FACIT-Sp) in a cohort of older patients admitted to rehabilitation. Method: Patients aged 65+, with MMSE score>19, admitted consecutively over 6 months in post-acute rehabilitation were enrolled (N=144, 81.27.2 years, 68.8% women). Data on medical, functional, and mental status were systematically collected upon admission. Spiritual well-being was assessed within 3 days after admission using the FACIT-Sp (12 items, score from 0 to 48, high spiritual well-being defined as a score ≥36) and the single question "Are you at peace?" (score from 0 to 10 on a visual analog scale). Results: FACIT-Sp scores ranged from 7 to 44(mean=29.87.7). Overall, 24.3% of the patients had high spiritual well-being. Internal consistency was optimal for total score (Cronbach's alpha =0.85). Itemto- total correlations were all significant, ranging from 0.28 to 0.73. A confirmatory factorial analysis yielded a 2-factor solution, consistent with Meaning and Faith proposed subscales and accounting for 52% of the variance . FACIT-Sp total score correlated positively with the question «Are you at peace ?» (Spearman's rho 0.49, P<.001) and negatively with depressive symptoms (Spearman's rho -0.37, P<.001), confirming FACIT-Sp validity. Compared to the others, patients with higher spiritual well-being had significantly better function at admission (Barthel's score 74.817.1 vs 68.514.1, P=.014). Conclusions: The FACIT-Sp remains a reliable and valid measure to assess spiritual well-being in older patients undergoing rehabilitation. The relatively low proportion of patients with high spiritual well-being deserves further investigation.

Sharpshooter leafhoppers (Hemiptera, Cicadellidae, Cicadellinae) in citrus groves of the area of Bebedouro, SP, with description of a new species of Acrogonia Stål. Sixteen species of Cicadellidae, subfamily Cicadellinae, were collected and identified: 11 of the tribe Cicadellini and five of the tribe Proconiini. The ten most common species, together with a new species, are characterized based on external morphology and male genitalia: Acrogonia citrina Marucci & Cavichioli sp. nov.; Bucephalogonia xanthophis (Berg, 1879); Dilobopterus costalimai Young, 1977; Ferrariana trivittata (Signoret, 1854); Hortensia similis (Walker, 1851); Macugonalia cavifrons (Stål, 1862); M. leucomelas (Walker, 1851); Oncometopia facialis (Signoret, 1854); Plesiommata corniculata Young, 1977 and P. mollicella (Fowler, 1900). The leafhopper samples were collected in citrus groves and in adjacent habitats (woods, swamp, cultivable plain, spontaneous vegetation of the grove, coffee crop and sugarcane) at the counties of Bebedouro and Monte Azul Paulista and in the district of TurvÃnia. The collecting methods were: insect net, yellow sticky cards, portable suction trap and Malaise trap. Identification keys were elaborated for the 16 species. There is a great diversity of Cicadellinae species in the citric groves. In the three areas sampled, it was collected a larger number of species of the tribe Cicadellini than of the tribe Proconiini. In the Bebedouro area, the vector species of Xylella fastidiosa, A. citrina sp. nov., B. xanthophis, D. costalimai and O. facialis, were collected in the citrus groves and in all adjacent habitats.
