Huylmer Lucena Chaves, Mayanna Pinho Batista, Germana Bastos Pontes, Lia Pontes de Melo, José Carlos Godeiro Junior
Open Journal of Radiology (OJRad) , 2019, DOI: 10.4236/ojrad.2019.91001
Abstract: A spontaneous portosystemic shunt is a rare malformation of the liver vessels. The etiology of these shunts is controversial. They can be divided into acquired (most commonly associated with liver cirrhosis) and congenital. Vascular shunts are asymptomatic in the majority of the patients, and when symptomatic were presented by severe complications. The specific way of management can be selected depended on whether the patient was symptomatic or not, and also on the size of the shunt, shunt ratio and whether it was associated with cancer. We will present a clinical case and discuss the importance of the radiological imaging in the screening, diagnosis and follow up of these anomalies.

Abstract:

Objectives: This study proposes to evaluate risk factors for kidney disease in HIV patients treated chronically and correlate with microalbuminuria measurements. Methods: Review charts and analyses of microalbuminuria in subgroup of HIV patients treated at Ceara/Brazil. Results: 149 patients, 69.1% male, mean 38.5 years old, infection mean 86.8 months. Mean Creatinine Clearance 110.2%, Creatinine 0.97, Urea 27.76 mg/dl, CD4+ 600.37 cels/mm3 and detectable viral load 530.59 copies with 61.7% undetectable. Mean Dosages of microalbuminuria/24h 147, 46 ± 820, 45 (N = 48) and microalbuminuria (mg/dl) 32.05 ± 85.25 (N = 43). Kidney Diseases Classification analyses evidenced 6.4% patients in stages ≥3 and 6.2% presented altered Microalbuminuria/24h. Patients using Tenofovir (TDF) 27.27% had Stage 2 and protease inhibitors (PI) had 4.1% in Stage 3. Proteinuria was observed in 5% stage ≥3. Association PI/TDF had 4.1% in Stage 3. No statistical difference between CD4 > or < 350 cels/mm3 and microalbuminuria/24h > 300 mg (p = 0.69); detectable/undetectable viral load and microalbuminuria/24h (p = 0.63) or stage ≥3 (p = 0.17); relation to Diabetes or arterial hypertension and microalbuminuria 24 h (p = 0.5 and p = 0.21); relation stage ≥3 and microalbuminuria/24h (p = 0.33); relation HIV diagnoses >/< 60 months and stage ≥3 (p = 0.51); or microalbuminuria/24h and TDF (p = 0.4), PI (p = 1), TDF/PI (p = 0.69), Atazanavir (p = 0.4) or Lopinavir/r (p = 1) regimens. There was statistical significance comparing age > or < 50 years and stage ≥3 (p = 0.001) without difference with age > or < 50 years and microalbuminuria/24h (p = 0.55) or microalbuminuria mg/d (p = 0.32). Relating comorbidities risk (Diabetes Mellitus plus Systemic Arterial Hypertension) to Kidney Diseases, it was found that 55.5% patients in Stage 3 or above with comorbidities compared with 15% with comorbidities in lower stages (P = 0.005).

Abstract: Objective: Due to the lack of studies assessing hypovitaminosis D and secondary hyperparathyroidism in Brazilian HIV-infected population, especially in the northeastern population, this study aimed to determine the profile of these conditions in patients infected with HIV and its correlation with immuno-virological, sociodemographic data and associated comorbidities. Methods: Comparison studies were obtained from routine clinical samples of HIV infected patients submitted for 25-OH Vitamin D, PTH and alkaline phosphatase determination. Results: A total of 78 patients were included, 42 (53.8%) males, mean age 45.7 years. Antiretroviral regimens most used in this study were Zidovudine/Lamivudine/Efavirenz 17.9%, Tenofovir/Lamivudine/Efavirenz 17.9%,Tenofovir/Lamivudine/Atazanavir-r 15.4%. The mean value CD4 count was 592.1 ± 247.2 cells/mm3, CD8 cell count was 1026.5 ± 467.3 cells/mm3, mean detectable viral load was 2220 ± 15703 copies and CD4/CD8 ratio was 0.63 ± 0.33. A total of 34 vitamin D dosages were collected with 41.2% representing sufficient amount and 58.8% insufficient. Alkaline Phosphatase (ALP) dosage was elevated in 49.3% (N=35) of the patients. Parathormone (PTH) was elevated in 18% (N = 11). Among patients with elevated PTH levels, 81.9% had elevated levels of ALP (p = 0.01). In the group of patients with high levels of ALP, 45.7% had a CD4 count < 500 cels/mm3 (p = 0.02). There was no significant difference in vitamin D related to gender (p = 0.21), age (p = 0.23), CD4 count (p =

Abstract: From January to March of 2005 one experiment was developed in a screen house to evaluate the effect of sources and levels of water salinity on emergence and initial development of papaya seedlings cv. Sunrise Solo. A completely randomized experimental design was used and treatments were distributed in a factorial arrangement 3×5, corresponding to three sources (dam water, water salinized with sodium and water salinized with sodium sulfate) and five water saline levels (0.4; 2.0; 4.0; 6.0 e 8.0 dS.m-1) and five replications. At 60 days after seedling emergence the following variables were evaluated: soil electrical conductivity, seedling emergence, plant height, stem diameter and dry mass of shoots and roots. The soil electrical conductivity increased independently of salt source, with more expressiveness for dam water, and all evaluated variables of plant growth were inhibited with water salinity increase. No período, de janeiro a mar o de 2005, foi desenvolvido um experimento em abrigo telado para avaliar o efeito de fontes e níveis de salinidade sobre a emergência e desenvolvimento inicial de plantulas de mam o Havaí cv. Sunrise Solo. Os tratamentos foram distribuídos em delineamento inteiramente casualizado, em esquema fatorial 3×5, correspondente a três fontes (água salina de barragem (AS), água concentrada em cloreto de sódio (NaCl) e água rica em sulfato de sódio (Na2SO4) e cinco níveis de salinidade (0,4; 2,0; 4,0; 6,0 e 8,0 dS m-1) em cinco repeti es. Aos 60 dias após a emergência foram avaliadas as seguintes variáveis: Condutividade elétrica do extrato de satura o do solo (CEes), % de emergência de sementes, altura de plantas, diametro caulinar na altura do colo e biomassa seca de parte aérea e raízes. A CEes do substrato foi elevada, independentemente da fonte utilizada, com maior expressividade para a água de barragem, e as variáveis de crescimento vegetativo avaliadas foram inibidas, independentemente da fonte utilizada, com o incremento da salinidade da água de irriga o.

Abstract: in recent years, public policy evaluation in brazil has become a strategic tool for improving the performance of public action, capable of contributing effectively to social welfare. despite this recognition, evaluative practice has still not been incorporated into the programs' "life cycle", especially in the social area. programs that lack significant evaluative practice include those related to food and nutrition. this article thus aimed to characterize the field of evaluation of public food and nutrition interventions in graduate studies programs in brazil. the study focused primarily on theses and dissertations from 1980 to 2004, converging on the functioning of interventions with a predominance of documental research and case studies. analytically, the principal thematic categories in these theses and dissertations have shifted from a more biological focus to the socio-political dimension.

Abstract: the following paper analyzes key aesthetic ideas from the avant-garde theoretical production of the arte concreto-invención, a group that in the mid-40s revolutionized the argentinean art field with a disruptive artistic and political proposal. as noted by the artists themselves, the aesthetic-political program of concrete art begins from the premises of historical materialism. while its basics are framed in marxist aesthetics, this categorization can be too wide for our analysis, due to the variety of proposals and conceptualizations that can be included within. that is why this paper will aim to define the specificity of the argentinean aesthetics of concreteness in relation to other aesthetics that define or consider themselves marxists. the work includes a review of primary sources that haven't been deeply considered, focusing primarily on the writings that tomás maldonado drawn between 1944 and 1954, which is where the artist defines his art proposal by arguing with other artists, intellectuals and other ways of understanding the relationship between art, reality and social transformation.

Abstract: a group composition study of the minke whale, balaenoptera bonaerensis (burmeister, 1867) captured in the waters of costinha, paraíba, brazil, was conducted with the aim of better understand the reproductive behavior of this species as well as the ecological characteristics of that population. in this study, the information gathered by superintendência para o desenvolvimento da pesca and companhia de pesca norte do brasil from 1975 to 1985 about the whale's group size and composition, sexual proportion, sexual maturity of the captured whales was analyzed. the groups found in the waters of costinha were in general of small size and composed by animals of both sexes, with a greater proportion of sexual mature and female animals. calves, lactating or pregnant females were rarely found. that population concentrated in higher number in the waters of costinha between september to october, the most important period for the species conception. a great number of conceptions might occur at this time in the area. the absence of lactating females and calves in the population demonstrate that births do not occur in this area. strandings and sightings of young minke whales in the south america east coast (between 25os e 40os) suggests that births occur at medium latitudes of this region, where the water temperature is inferior to that one in the northeast brazilian coast. in that way, the possibility of the existence of distinct areas to births and breeding activities of minke whales in the south atlantic ocean might be considered. the polygamy is a reproductive behavior of minke whale, observed by the composition and sexual proportion of groups composed by sexual mature animals in this breeding ground.
Algunas consideraciones sobre la estética materialista de la Asociación Arte Concreto-Invención A few Considerations on the Materialist Aesthetics of Asociación Arte Concreto-Invención

Abstract: El siguiente trabajo analiza las principales ideas estéticas de la producción teórica de la vanguardia Arte Concreto-Invención, grupo que a mediados de los a os 40 revolucionó el campo artístico argentino con una disruptiva propuesta artístico-política. Tal como se alan los propios artistas, el programa estético-político del arte concreto parte de las premisas del materialismo histórico. Si bien las bases y los fundamentos del concretismo se encuentran enmarcados dentro de la estética marxista, esa categorización resulta amplia para el análisis, debido a la gran variedad de planteos y conceptualizaciones que pueden incluirse dentro de la misma. Es por esto que el presente estudio busca delimitar la especificidad de la estética del concretismo argentino en relación con otras estéticas que se autodefinen o se consideran marxistas. El trabajo incluye una revisión de fuentes primarias hasta ahora poco estudiadas y se focaliza, fundamentalmente, en los escritos de Tomás Maldo-nado entre 1944 y 1954, puesto que es allí donde el artista explicita la propuesta del arte concreto polemizando, a su vez, con otros artistas, otros intelectuales y otras formas de comprender las relaciones entre arte, realidad y transformación social. The following paper analyzes key aesthetic ideas from the avant-garde theoretical production of the Arte Concreto-Invención, a group that in the mid-40s revolutionized the Argentinean art field with a disruptive artistic and political proposal. As noted by the artists themselves, the aesthetic-political program of Concrete Art begins from the premises of historical materialism. While its basics are framed in Marxist aesthetics, this categorization can be too wide for our analysis, due to the variety of proposals and conceptualizations that can be included within. That is why this paper will aim to define the specificity of the Argentinean aesthetics of concreteness in relation to other aesthetics that define or consider themselves Marxists. The work includes a review of primary sources that haven't been deeply considered, focusing primarily on the writings that Tomás Maldonado drawn between 1944 and 1954, which is where the artist defines his art proposal by arguing with other artists, intellectuals and other ways of understanding the relationship between art, reality and social transformation.
