RESUMO JUSTIFICATIVA E OBJETIVOS: Recomenda-se a utilização de cartilhas socioeducativas para auxiliar no controle da dor crônica (DC). No entanto, a eficácia e a segurança dessas tecnologias leves foram pouco testadas para ampla aplicação, com base no modelo de evidências científicas. Este estudo teve como objetivo avaliar o efeito de um programa de educação em saúde em indivíduos com DC por meio da cartilha EducaDor. MÉTODOS: Ensaio clínico randomizado realizado com indivíduos que apresentam DC em Unidades Básicas de Saúde (UBS) de Salvador, Bahia, Brasil. Os participantes foram submetidos à aplicação do Inventário Breve de Dor (BPI), Escala Analógica Visual (EAV) e do instrumento de Qualidade de Vida da Organização Mundial da Saúde - Bref (WHOQoL-bref ), antes e após a intervenção, para análises intra e intergrupos: Grupo Teste (booklet) e Grupo Controle (cuidado convencional). O conteúdo da cartilha EducaDor foi apresentado didaticamente em seis encontros com intervalo de uma semana entre eles. RESULTADOS: A amostra foi composta por 10 pessoas em cada grupo (n = 20). No Grupo Controle, houve aumento da intensidade da dor (p=0,034), enquanto o Grupo Teste apresentou redução da intensidade de dor (p=0,015) e menor nível de interferência nos domínios de qualidade de vida físico, psicológico, social e ambiental (p<0,05). Nas comparações intergrupos, observou-se melhora no domínio relações sociais no Grupo Teste (p=0,015). CONCLUSÃO: A cartilha EducaDor mostrou-se eficaz e segura para a educação de pacientes com DC, por reduzir a intensidade da dor e melhorar a qualidade de vida dos pacientes.

ABSTRACT BACKGROUND AND OBJECTIVES: The use of socio-educational booklets is recommended for assisting in the control of chronic pain. However, the efficacy and safety of these light technologies have not yet been tested enough for widespread application, based on the model of scientific evidence. This study aimed to assess the effect of a health education program in individuals suffering from CP using the EducaDor booklet. METHODS: Randomized clinical trial conducted with chronic pain patients from Unidades Básicas de Saúde (UBS – Primary Health Care Units) in Salvador, Bahia, Brazil. Assessments were performed using the Brief Pain Inventory (BPI), Visual Analog Scale of Pain (VAS-P) and World Health Organization Quality of Life instrument-Bref (WHOQoL-bref ), before and after the intervention, for intra and intergroup analyses: Test Group (Booklet) and Control Group (Conventional Care). The contents of the EducaDor booklet were presented didactically in six meetings with an interval of one week between them. RESULTS: The sample was composed of 10 individuals in each group (n = 20). In the Control Group, there was an increase in pain intensity (p=0.034), while the Test Group showed a reduction in pain intensity (p=0.015) and a lower level of interference in the physical, psychological, social relationships and environmental quality of life domains (p<0.05). In the intergroup comparisons, an improvement was observed in the domain of social relationships in the Test Group (p=0.015). CONCLUSION: EducaDor booklet has been shown to be effective and safe for the education of patients suffering from CP by reducing pain intensity and improving patients’ quality of life.

Abstratc This work reports the production of low-tin Cu-Sn alloy coatings on carbon steel substrates using a bath containing CuCl2, SnCl2, and sodium citrate. In the first part of this study, the coatings were electrodeposited by direct and simple pulse current processes (DC and SPC, respectively). Different current density values were used, while the pulse frequency and duty cycle remained constant. Independent of the current mode used, low-tin Cu-Sn coatings, showing globular surface morphology and Cu6Sn5 as the main compositional phase, were produced. Both the current mode and the applied current density affected the anticorrosive properties of the coatings. The most protective DC and SPC coatings, showing Sn content < 3 wt.% and compact morphology, were prepared using j = 80 A m-2 and jc = 167 A m-2, respectively. High charge transfer resistance values were verified even after immersion for 24 h in 0.5 mol L-1 NaCl solution.

Resumo O objetivo do presente trabalho foi determinar a soropositividade paraLeishmania spp. e Trypanosoma cruzi em cães do Estado da Paraíba, Nordeste do Brasil, bem como identificar fatores de risco. Foram utilizados 1.043 cães e, para o diagnóstico sorológico de doença de Chagas (DC) e leishmaniose visceral canina (LVC), foi utilizada a reação de imunofluorescência indireta (RIFI). Animais positivos para ambas as doenças (pela RIFI) foram submetidos ao ELISA. Dos 1.043 cães investigados, 81 foram soropositivos para Leishmania spp., resultando em prevalência de 7,8% (IC 95% = 6,1-9,4%) e, para T. cruzi, 83 (7,9%; IC 95% = 6,3-9,6%) animais foram soropositivos. Quarenta e nove animais (4,6%; IC 95% = 3,6-6,2%) apresentaram sororeatividade mista. Criação semidomiciliar (OR = 2,044), criação solta (OR = 4,151), ambiente de terra (OR = 3,425) e ambiente de terra/cimento (OR = 3,065) foram apontados como fatores de risco para LVC, e criação semidomiciliar (OR = 2,353), criação solta (OR = 3,454) e contato com bovinos (OR = 2,015) para DC. Conclui-se que LVC e DC estão presentes em cães do Estado da Paraíba, o que sugere revisão e intensificação das medidas de controle através do constante monitoramento da população canina.

Abstract The aim of this survey was to determine the seropositivity and risk factors forLeishmania spp. and Trypanosoma cruzi in dogs in the State of Paraíba, Northeastern Brazil. A total of 1,043 dogs were tested, and the serological diagnoses of Chagas disease (CD) and canine visceral leishmaniasis (CVL) was performed by the indirect fluorescent antibody test (IFAT). Animals that tested seropositive for both diseases (by IFAT) were further subjected to ELISA. Of the 1,043 dogs 81 (7.8%; 95% CI = 6.1-9.4%) tested seropositive for Leishmania spp., while 83 were seropositive for T. cruzi (7.9%; 95% CI = 6.3-9.6%). Simultaneous serological reactions were detected in 49 animals (4.6%; 95% CI= 3.6-6.2%). Semi-domiciled housing (OR = 2.044), free housing (OR = 4.151), and soil (OR = 3.425) and soil/cement (OR = 3.065) environmental conditions were identified as risk factors for CVL seropositivity. The risk factors identified for CD seropositivity were semi-domiciled (OR = 2.353) or free housing (OR = 3.454), and contact with bovine (OR = 2.015). This study revealed the presence of dogs in the Paraíba State seropositive for CVL and CD, suggesting the need for revisiting and intensification of disease control measures through constant monitoring of the canine population.

Amphibian skin secretions are a source of potential new drugs with medical and biotechnological applications. Rich in peptides produced by holocrine-type serous glands in the integument, these secretions play different roles, either in the regulation of physiological skin functions or in the defense against predators or microorganisms. The aim of the present work was to identify novel peptides with bradykinin-like structure and/or activity present in the skin of Phyllomedusa nordestina. In order to achieve this goal, the crude skin secretion of this frog was pre-fractionated by solid phase extraction and separated by reversed-phase chromatography. The fractions were screened for low-molecular-mass peptides and sequenced by mass spectrometry. It was possible to identify three novel bradykinin-related peptides, namely: KPLWRL-NH2 (Pnor 3), RPLSWLPK (Pnor 5) and VPPKGVSM (Pnor 7) presenting vascular activities as assessed by intravital microscopy. Pnor 3 and Pnor 7 were able to induce vasodilation. On the other hand, Pnor 5 was a potent vasoconstrictor. These effects were reproduced by their synthetic analogues.

O papel da craniotomia descompressiva (CD) no tratamento da hipertensão intracraniana (HIC) refratária ainda não está estabelecido na literatura. Atualmente é recomendada como opção, pois há deficiência de trabalhos classe I ou II que suportem seu emprego. Trabalhos recentes têm avaliado a eficácia da CD quando aplicada precocemente no tratamento da HIC pós traumática. No presente trabalho analisam-se 21 pacientes nos quais a CD foi realizada precocemente. A maioria dos pacientes apresentava traumatismo cranioencefálico grave (Escala de coma glasgow <9) e tomografia de crânio evidenciando tumefação cerebral (brain swelling) ou hematoma subdural agudo. A principal complicação inerente à técnica foi a hidrocefalia (28,5%). Boa reabilitação social ocorreu em 11 pacientes (52,5%). Parece que a CD, quando realizada precocemente, é eficaz no tratamento da HIC refratária, ressaltando-se ainda a necessidade de estudos classe I e II que suportem esta opinião.

There is no clear role for decompressive craniotomy (DC) for the intracranial hypertension (ICH) treatment in the literature. Actually, there is a lack of class I or II published data for DC, so it is recomended as a second tier option for the refractory ICH. Recent studies has analized the role of early DC for pos traumatic ICH. The present study analizes 21 patients who has received the early DC for the treatment of traumatic ICH. The majority of the patients had Glasgow Coma Scale < 9 and harboring a brain swelling or acute subdural hematoma at cranial computadorized tomography. Hydrocephalus was frequent after DC (28.5%). Good results were obtained in 11 patients (52.5%). We favour the early application of DC for pos traumatic hypertension.

Esse trabalho estuda três espécies medicinais de Compositae, descrevendo características morfo-histológicas e relacionando as características físico e fito-químicas com as variações sazonais. Os teores de umidade e de cinzas parecem não sofrer alterações expressivas em função da estação do ano. Bacharis trimera DC (carqueja) não mostrou diferenças qualitativas em seus princípios ativos, que foram detectados tanto na primavera, como no verão e no inverno: saponinas e flavonóides. Solidago microglossa DC (arnica) apresentou alcalóides no verão e no inverno, na primavera não. Flavonóides e taninos, contudo, não apresentaram essa variação. Achillea millefolium L. revelou presença de alcalóides, heterósides cianogéticos, taninos e flavonóides durante o ano todo. A fração saponínica, contudo, falta no verão, justamente quando aparecem os fenóis, ausentes na primavera e no inverno.

This work deals with three medicinal species of Compositae in relation to the botanic-diagnostic, physical-chemistry and phytoterapic aspects, considering the seazonal variations. The level of humidity and ashes seems to have no seazonal variations. Bacharis trimera DC did not shows qualitative variations in its composition of saponins and flavonoids. Solidago microglossa DC presented alkaloids only at the summer and winter. Its flavonoidic and tanninic compositions, however, did not shows qualitative variations. Achillea millefolium L. has alkaloids, cianogenic heterosides, tannins and flavonoids all the year long. The saponinic fraction lacks at the summer however, just when the phenols show up, after disappearance at the spring and in the winter.
