The aetiology of autoimmunes disease is multifactorial and involves interactions among environmental, hormonal and genetic factors. Many different genes may contribute to autoimmunes disease susceptibility. The major histocompatibility complex (MHC) genes have been extensively studied, however many non-polymorphic MHC genes have also been reported to contribute to autoimmune diseases susceptibility. The aim of the present study was to evaluate the influence of SLC11A1 gene in systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Ninety-six patients with SLE, 37 with RA and 202 controls enrolled in this case-control study, were evaluated with regard to demographic, genetic, laboratorial and clinical data. SLE mainly affects females in the ratio of 18 women for each man, 88,3% of the patients aged from 15 to 45 years old and it occurs with similar frequency in whites and mulattos. The rate of RA between women and men was 11:1, with 77,1% of the cases occurring from 31 to 60 years. The genetic analysis of the point mutation -236 of the SLC11A1 gene by SSCP did not show significant differences between alleles/genotypes in patients with SLE or RA when compared to controls. The most frequent clinical manifestations in patients with SLE were cutaneous (87%) and joint (84.9%). In patients with RA, the most frequent out-joint clinical manifestation were rheumatoid nodules (13,5%). Antinuclear antibodies were present in 100% of the patients with SLE. There was no significant relation between activity of disease and presence of rheumatoid factor in patients with RA, however 55,6% of patients with active disease presented positive rheumatoid factor. Significant association between alleles/genotypes of point mutation -236 and clinical manifestations was not found

Resumen Los equinos deportivos, son víctimas de frecuentes heridas en la región distal de los miembros y de fracturas articulares. La medicina regenerativa es un campo emergente el cual utiliza métodos alternativos para diferentes lesiones de difícil resolución con tratamiento convencional. Existen antecedentes que utilizan parches de fibrina (PF) en la reparación de heridas cutáneas y plasma rico en plaquetas (PRP) en lesiones osteoarticulares. Este trabajo tuvo por objetivo evaluar la aplicación de PRP sobre una fractura de tercer carpiano del miembro anterior derecho y la aplicación de PF en una herida de 54 cm² en la región metatarsiana del miembro posterior izquierdo de un equino Sangre Pura de Carrera (SPC). Se realizó una única aplicación PRP mediante artrocentesis intercarpiana. Sobre la herida cutánea, se realizaron 3 aplicaciones (1 por semana) de PF. Un mes post-aplicación de PRP el equino ya no evidenciaba claudicación, no manifestaba dolor ni inflamación articular y no rechazaba el apoyo. A nivel radiográfico, se observó consolidación de la línea de fractura, con remodelación ósea. A su vez, luego de la tercera aplicación de PF (3 semanas), la superficie de la herida se redujo dos tercios del tamaño original y a las 8 semanas se logró su completa resolución

Sandflies stand out as important vectors of leishmaniasis. The females need to ingest blood meals, enabling them to transmit protozoa of the genus Leishmania, which may give rise to visceral leishmaniasis (VL) or American tegumentary leishmaniasis (ATL), in addition to transmitting other parasites. Leishmaniasis are important infirmities, distributed worldwide, whose infection results from the interaction of reservoir animals, the vector insect, parasitic protozoa and the healthy host. In the state of Rio Grande do Norte (RN), Brazil, these insects are important transmitters of VL, which usually presents in the most serious form. It occurs mainly in metropolitan areas, with the dog as its main reservoir and Lutzomyia longipalpis as the vector. ATL is most present in the highland areas of the state. In addition to hematophagia, engaged in by the females, both sexes need to ingest carbohydrates, which are essential to the sand flies energy requirements and may interfere in the development of Leishmania. The aim of this study was to determine the occurrence and abundance of sand flies in different environments on the farm belonging to the Empresa de Pesquisas Agropecuárias do RN (Institute of Agricultural Research of RN), in the municipality of Parnamirim, in order to relate this occurrence with climatological and biological references and eating habits. Three consecutive monthly collections were carried out with CDC traps in a fragment of the Atlantic Forest, in a residence, on a goat breeding farm and on cashew, dwarf and giant coconut, mango, banana, eucalyptus, acacia and bean plantations. A total of 1241 sandflies from eight species (Lutzomyia evandroi, Lutzomyia longipalpis, Lutzomyia shannoni, Lutzomyia sordellii Lutzomyia walkeri, Lutzomyia wellcomei, Lutzomyia whitmani, and Lutzomyia intermedia) were collected, most in the forest environment. L. longipalpis, the main VL transmitter, was confirmed as a species adapted to anthropic environments, whereas others such as L. wellcomei, the vector of ATL, occurred predominantly in forests. Carbohydrate characterization of the sand flies and plants of the region demonstrated that a number of exotic plants such as hay and eucalyptus may play some role in the adaptation of these species to modified environments. Breeding in laboratory showed a mean biological cycle of 53.5 days from egg to adulthood for L. shannoni and the possibility of diapause behavior in L. wellcomei. This study serves as a source of information that may contribute to the epidemiological vigilance of tegumentary and visceral leishmaniasis in the state, given that it analyzes the bioecology of transmitting species, as well as their potential to adapt to new environments

GB virus type C (GBV-C) appears to promote a Th1 response and is associated with prolonged survival in HIV-infected people. L. chagasi causes a spectrum of illness that varies from severe visceral leishmaniasis, a disease that in the majority of cases is fatal if not treated, to self resolution of infection and development of positive DTH response that is protective against symptomatic disease. To determine if GBV-C viremia might influence the outcome of Leishmania infection, we characterized GBV-C status in a cohort of subjects residing in a L. chagasi endemic area in Brazil. GBV-C viremia was more prevalent in blood donors from urban than in periurban regions of Natal, Brazil (16% and 7.5% respectively). Evidence of prior GBV-C (anti-E2 antibodies) was detected in 24% and 12%of these groups respectively. Anti-E2 increased with age (p= 0.0121). No difference in GBV-C viremia was found in the DTH+ and VL groups (p= 0.269); however, subjects with visceral leishmaniasis were more likely to have anti-E2 than DTH+ subjects (p=0.0012), and DTH induration was smaller in subjects with E2 antibodies (4.5 mm) compared those without (7.12 mm) (p= 0.002). Furthermore, the size of the Leishmania DTH response was greater in GBV-C viremica subjects (6.8 mm) compared to non-viremic subjects (3.3 mm; p= 0.0054). There findings suggest that GBV-C virus may promote a type 1 immune response that could influence the outcome of Leishmania infection

A psoríase é uma doença inflamatória cutânea crónica, prevalente em ambos os géneros, com incidência mundial de 1 a 3 %, estando associada a uma alteração física e a uma assolação psicológica, que condiciona intimamente a interação da pessoa com o meio envolvente. A questão de investigação reiterante desta Revisão Integrativa da Literatura é: "Qual o impacto da psoríase no autoconceito e na socialização?", tendo como objetivos: compreender o impacto psicossocial da psoríase; compreender a influência das lesões no autoconceito e na socialização da pessoa com psoríase; identificar as Intervenções de Enfermagem para um cuidado com qualidade. A pesquisa foi efetuada, através da definição das palavras-chave "Intervenções de Enfermagem", "Psoríase", "Autoconceito", "Socialização" nos motores de busca B-on e EBSCOhost. Após aplicação de critérios de inclusão e de exclusão e do método PI[C]OD, obtiveram-se 6 artigos científicos. Conclui-se que a psoríase condiciona fortemente a autoimagem, induzindo a diminuição do autoconceito; a pessoa, na tentativa de mascarar a desfiguração física, adota comportamentos que a impedem de estabelecer relações; o enfermeiro deve desenvolver uma relação de ajuda com a pessoa que vise a redução do impacto desta patologia.

O presente relatório diz respeito ao estágio curricular realizado no Hospital Veterinário de Portimão, sob a orientação da Prof. Doutora Josefina Coucelo e com a duração de cinco meses, entre um de janeiro de 2016 e trinta e um de maio de 2016. Este relatório foi realizado no âmbito da conclusão do Mestrado Integrado em Medicina Veterinária e consiste em duas partes. A primeira é referente aos casos acompanhados no decorrer do estágio curricular, e a segunda é uma revisão bibliográfica do tema “Leishmaniose Felina”, seguida de um caso clínico acompanhado pelo autor. A Leishmaniose é uma importante zoonose, endémica em várias regiões no mundo, como o sul da Europa, afetando variados mamíferos, debilitando-os e podendo ser fatal. Causada por protozoários do género Leishmania, considera-se como uma afeção rara em gatos. Existe um número crescente de casos nesta espécie, que não é, no entanto, reservatório da infeção para humanos; Small Animal Practice Abstract: The present report describes a training in Portimãos’s Veterinary Hospital, under Doctor Josefina Coucelo’s supervision with the duration of five months, between the 1st January 2016 and the 31st May 2016. This report was written in the context of the Veterinary Medicine Integrated Master degree’s conclusion and is made up of two parts. The first refers to the clinical cases followed during the training and the second is a monography about “Feline Leishmaniasis”, followed by a case report on the subject observed by the author. Leishmaniasis is an important zoonosis endemic in many world regions as well as in southern Europe, affecting many mammals debilitating them and sometimes fatal. It is caused by protozoan of the genus Leishmania. It’s considered a rare affection in cats, however, there’s an increasing number of cases in this host species which still isn’t considered a human infection reservoir.
