A presente pesquisa versa sobre a interiorização da Perícia Criminal da Polícia Federal, que consiste num projeto de implantação de Unidades Técnico-Científicas para a execução de exames periciais em algumas cidades do interior do Brasil onde existem delegacias da Polícia Federal. Após a abertura das primeiras unidades no interior do país surgiram alguns resultados positivos. Entretanto, também surgiram situações indesejáveis e aspectos negativos que não foram previstos. O objetivo do estudo foi avaliar as vantagens e as desvantagens da instalação de Unidades Técnico-Científicas no interior do país para a administração da Perícia Criminal Federal. A pesquisa foi realizada com 59 chefes das unidades de perícia criminal das capitais dos estados e das unidades do interior. O estudo demonstrou que alguns resultados positivos foram alcançados, como a maior rapidez no atendimento e a melhor interação com o usuário do serviço de perícia criminal. Mas foi constatado também que existem problemas relacionados à infraestrutura, recursos humanos e materiais nas unidades do interior. Com o estudo foi possível concluir que a continuidade do programa de interiorização da perícia criminal federal depende preliminarmente da realização dos investimentos necessários em recursos humanos e materiais para que as unidades atualmente existentes possam ter as condições adequadas para seu funcionamento.

Brazilian public policy entered in the so-called new social federalism through its conditional cash transfers. States and municipalities can operate together through the nationwide platform of the Bolsa Familia Program (BFP), complementing federal actions with local innovations. The state and the city of Rio de Janeiro have created programs named, respectively, Renda Melhor (RM) and Família Carioca (FC). These programs make use of the operational structure of the BFP, which facilitates locating beneficiaries, issuing cards, synchronizing payment dates and access passwords and introducing new conditionalities. The payment system of the two programs complements the estimated permanent household income up to the poverty line established, giving more to those who have less. Similar income complementation system was subsequently adopted in the BFP and the Chilean Ingreso Ético Familiar, which also follow the principle of estimation of income used in the FC and in the RM. Instead of using the declared income, the value of the Rio cash transfers are set using the extensive collection of information obtained from the Single Registry of Social Programs (Cadastro Único): physical configuration of housing, access to public services, education and work conditions for all family members, presence of vulnerable groups, disabilities, pregnant or lactating women, children and benefits from other official transfers such as the BFP. With this multitude of assets and limitations, the permanent income of each individual is estimated. The basic benefit is defined by the poverty gap and priority is given to the poorest. These subnational programs use international benchmarks as a neutral ground between different government levels and mandates. Their poverty line is the highest of the first millennium goal of the United Nations (UN): US$ 2 per person per day adjusted for the cost of living. The other poverty line of the UN, US$ 1.25, was implicitly adopted as the national extreme poverty line in 2011. The exchange of methodologies between federal entities has happened both ways. The FC began with the 575,000 individuals living in the city of Rio de Janeiro who were on the payroll of the BFP. Its system of impact evaluation benefited from bi-monthly standardized examinations. In the educational conditionalities, the two programs reward students' progress, a potential advantage for those who most need to advance. The municipal program requires greater school attendance than that of the BFP and the presence of students’ parents at the bimonthly meetings held on Saturdays. Students must achieve a grade of 8 or improve at least 20% in each exam to receive a bi-monthly premium of R$50. In early childhood, priority is given to the poor children in the program Single Administrative Register (CadÚnico) to enroll in kindergarten, preschools and complementary activities. The state program reaches more than one million people with a payment system similar to the municipal one. Moreover, it innovates in that it transfers awards given to high school students to savings accounts. The prize increases and is paid to the student, who can withdraw up to 30% annually. The total can reach R$3,800 per low-income student. The State and the city rewarded already education professionals according to student performance, now completing the chain of demand incentives on poor students and their parents. Increased performance is higher among beneficiaries and the presence of their guardians at meetings is twice compared to non beneficiaries; The Houston program, also focuses on aligning the incentives to teachers, parents and students. In general, the plan is to explore strategic complementarities, where the whole is greater than the sum of its parts. The objective is to stimulate, through targets and incentives, synergies between social actors (teachers, parents, students), between areas (education, assistance, work) and different levels of government. The cited programs sum their efforts and divide labor so as to multiply interactions and make a difference in the lives of the poor.

O Brasil, a exemplo de outros países, passou a adotar políticas de ação afirmativa com a finalidade de compensar grupos sociais que se encontram em posição desfavorável, usualmente em razão de um passado de discriminação, proporcionando-lhes a fruição de direitos fundamentais. Desde a última década, a maior parte das medidas aprovadas tinha como foco a educação, em especial o acesso às universidades públicas de alta qualidade. Já a reserva de vagas em concursos públicos, embora já vigorasse em diversos municípios, só começou a ganhar espaço no debate social e na agenda governamental recentemente, a partir de sua implementação por parte de estados e da aprovação do Estatuto da Igualdade Racial, que prevê a aplicação de políticas de ação afirmativa como maneira a permitir a participação da população negra em condição de igualdade na vida econômica, social, política e cultural do País. Dados do Ministério do Planejamento, Orçamento e Gestão indicam que, apesar de representarem a metade da população brasileira, negros e pardos ocupam menos de 30% dos cargos do Poder Executivo. Nas carreiras mais bem remuneradas, como as de nível superior, a presença dos negros é ainda mais reduzida. Em resposta a esse cenário de desigualdades, foi sancionada Lei nº 12.990, de 9 de junho de 2014, que reserva aos negros 20% das vagas oferecidas nos concursos públicos no âmbito da administração pública federal. O objetivo deste projeto é avaliar os desdobramentos do sistema de cotas implementado pela referida lei, que utiliza exclusivamente critério de natureza racial. Tenciona-se verificar se tal mecanismo é capaz de tornar menos excludente o acesso ao serviço público federal, de forma a contribuir para o debate a respeito das ações afirmativas.

High carotid artery resistance indices in the elderly arise mainly as a result of harmful daily lifestyle behavior and poor eating habits. The aim of this multidisciplinary study was to assess and correlate carotid artery resistance and functional autonomy in elderly women. A descriptive, exploratory cross-sectional study was conducted with a sample comprising 27 women, enrolled in pastoral programs in the city of Teresina, Brazil. Carotid artery resistance was assessed by a high-resolution Doppler ultrasound device and functional autonomy was evaluated through five protocol tests of the Latin American Development Group for the Elderly (GDLAM), simulating activities of daily life. The data were analyzed by the Shapiro-Wilk test and the correlation by Spearman s test, considering a p-value of <0.05. The sample consisted of women with mean age and standard deviation of (68.67 ± 4.52) years, respectively and carotid resistance index of (0.71 ± 0.07). The general index value of functional autonomy classified the elderly of the study group as weak in the performance of activities of daily living (30.46 ± 6.31). The general index of functional autonomy showed a high level of sedentary behavior in the group studied (p < 0.01). The sample was classified as weak in the performance of activities of daily life. The correlation coefficient between the carotid resistance index and the general GDLAM index was r = 0.998 and p = 0.000, showing a significant correlation. The elderly women assessed had a high carotid artery resistance index and low functional autonomy; a positive correlation was found between the dependent variables studied. To perform this study we formed a team composed of a nurse, who helped in organizing the sample and performing the examinations; a radiologist, who conducted the Doppler examinations; an angiologist, who collaborated in interpreting examination data; in addition to two physical education professors and two physical therapists, who applied the functional autonomy tests and conducted the 34 research along elderly health lines, contributing thus to the multidisciplinary character, fundamental for carrying out the study

In Brazil school food is constitutionally guaranteed to public school students at the preschool and elementary level. This food must be nutritious, hygienic and sanitary. The aim of the present study was to assess the hygienic/sanitary conditions of food and table utensil handlers in municipal public schools in Natal, Brazil. In total, 27 public schools were assessed, using a checklist and microbiological analysis of the hands and table utensils. For the microbiological analyses of the hands, coliforms were analyzed at 45ºC and for the utensils aerobic mesophilic bacteria, using methods recognized by AOAC, 2002 and APHA, 1992, respectively. Most of the schools studied did not exhibit good food and utensil handling practice procedures in any of the variables analyzed. It was shown that 74.1% of the handlers received no periodic training, 51.9% did not undergo annual health examinations and 100% did not practice proper hand hygiene, which reflected significantly (p < 0.05) in hand contamination, where fecal coliforms were detected on 55.6% of the hands analyzed. With respect to the utensils, it was found that 100% of the schools studied did not follow correct hygiene practices and most were classified as very bad ; that is, aerobic mesophilic bacteria values above the limits established by PAHO (Pan American Health Organization), with schools in the north and south districts recording the highest percentages. The results show that the hygienic-sanitary conditions of the food and utensil handlers in the schools studied were inadequate, demonstrating the need for implanting good handling practices aimed at protecting the health of children that take part in the program and offering safer foods. Researchers from the areas of food microbiology, nutrition, public health and statistics participated in this study, a decisive factor for characterizing it as multidisciplinary

The biliopancretic diversion with duodenal switch is one of the mixing techniques used in the treatment of morbid obesity. The duodenal switch reduces the stomach capacity and leaves only 50-100 cm of small intestine for nutrition and absorption. The surgery produces hormonal, structural and biochemical changes, which can influence on the result of scintigraphic examinations in operated patients. With the objective of evaluate the postoperative biodistribution of sodium pertechnetate (Na99mTcO4) in brain, thyroid, heart, lung, liver, spleen, kidney, stomach, duodenum, pancreas, small intestine, bladder, muscle and bone of Wistar rats. The rats were randomly allocated into 3 groups of 7 rats each: the duodenal switch group (DS), the control group (C) and the sham group (S). They were operated under anesthesia and aseptic technique. In the tenth postoperative day, 0.1mL of sodium pertechnetate was injected via orbital plexus. After 30 min the animals were killed with overdose of anesthetic and samples of liver, spleen, pancreas, stomach, duodenum, small intestine, thyroid, lung, heart, kidney, bladder, muscle, bone and brain were harvested, washed with saline and weighed. The detention of radioactivity was made using the automatic Gamma Counter Wizard, PerkinElmer and the percentage of activity per gram of tissue (%ATI/g) was calculated. There was no early or late mortality in either rats groups. The values of percent radioactivity per gram of tissue (%ATI/g), showed no significant difference in liver, stomach, small bowel, duodenum, kidney, heart, bladder, bone and brain, when compared the DS rats with sham and controls rats. A postoperative significant increase in mean %ATI/g levels was observed in spleen, pancreas and muscle in group DS rats, as compared to group S and C rats (p<0.05). In the lung there was an increase and in thyroid a decrease in mean %ATI/g of DS rats, when compared to sham rats (p>0.05). In conclusion, the biliopancreatic diversion with duodenal switch in rats modified the biodistribution of sodium pertechnetate in thyroid, lung, pancreas, spleen and muscle. The study had the participation of the departments and laboratories researches, as Nucleus of Experimental Surgery, Department of Surgery, Laboratory of Radiobiology, Department of Pathology and Service of Nuclear Medicine, certifying the character of a multidisciplinary research

The objective of the present study was to investigate the prevalence of Cryptosporidium (Apicomplexa, Cryptosporidiidae) in the snake Crotalus durissus terrificus (Serpentes, Viperidae). Fifty animals were evaluated for the presence of oocysts of Cryptosporidium sp. at the time of arrival and 30 and 60 days later. Intestinal washings with saline solution (1% body weight), fecal samples, and organ scrapings were collected during the study. Oocysts were concentrated by an ether-phosphate-buffered saline sedimentation technique and then separated by a density gradient centrifugation technique. Smears were made with the sediment and submitted to modified acid-fast and auramine-rhodamine staining. Cryptosporidium-positive smears were used as controls for the experimental findings. The overall prevalence of Cryptosporidium sp. oocysts was 14%. Among the positive snakes, oocysts were detected only in the intestinal washing in two specimens, only in the feces in four specimens, and in both materials at least once in one specimen. The positive snakes were predominantly from Santa Maria da Serra city State of São Paulo (57.1%). We also observed that all of the examinations that presented positive results were obtained at least 27 days after the capture of the animals.

Beta thalassemia arises as a consequence of the reduction (β+, β++, βsilent) or absence (β0) of beta globin chain synthesis and results from a number of mechanisms that lead to genetic defects. The inheritance of beta thalassemia is characterized by the existence of heterozygous individuals, compound heterozygotes, homozygotes and those with coinheritance of beta thalassemia allele and other thalassemias and/or hemoglobin variants. The aim of this study was to perform molecular and laboratory characterization of beta thalassemia in heterozygous and homozygous individuals and in those with coinheritance of S beta thalassemia. A total of 48 individuals were included (35 heterozygotes, 4 homozygotes and 9 S beta thalessemia carriers) referred to the Integrated Laboratory of Clinical Analyses of the Federal University of Rio Grande do Norte (UFRN) and the Hematology Ambulatory Facility of the Dalton Barbosa Cunha Hemocenter (Hemonorte Natal, Brazil). Peripheral blood samples form each patient underwent the following laboratory examinations: erythrogram, hemoglobin electrophoresis at alkaline pH, measurements of Hb A2, Fetal Hb and serum ferritin. DNA was extracted using the illustra blood genomicPrep Mini Spin Kit and molecular characterization was performed by the PCR/RFLP technique, which involves digestion with specific restriction enzymes for IVS-1 nt 1 (G®A), IVS-1 nt 6 (T®C) and codon 39 (CAG®TAG) mutations. Of the 35 heterozygotes, 37.1% showed IVS-1 nt 6 mutation, 42.9% IVS-1 nt 1 and 20% were carriers of other mutations not identified by the technique used. The four homozygous patients presented with the IVS-1 nt 6 mutation, while 66.7% of the individuals with S beta thalassemia had the IVS-1 nt 1 mutation. Codon 39 was not detected in any of the patients investigated. Of the thallasemic alleles found, 40.4% were IVS- 1 nt 1, 40.4% IVS-1 nt 6 and 19.2% were not identified. Laboratory data showed that the heterozygotes exhibited microcytosis and hypochromia, evidenced by MCV ranging from 57 to 75fL and MCH from 15.9 to 23.6 pg. Hemoglobin A2 varied between 3.7 and 7.2%. The homogygotes also showed reduced MCV and MCH and elevated HbA2.. Comparison of laboratory data between heterozygous individuals with IVS-1 nt 1 and IVS-1 nt 6 mutations showed that heterozygotes for the IVS1-1 mutation had significantly lower mean MCV and MCH (p = 0.023 and 0.007, respectively) and significantly higher hemoglobin A2 (p < 0.001) when compared to heterozygotes for the IVS-1 nt 6 mutation. PCR/RFLP was useful in identifying the presence or absence of IVS-1 nt 6, IVS-1 nt 1 and codon 39 mutations in most of the patients investigated here. This is the first study conducted in the state of Rio Grande do Norte, Brazil aimed at identifying beta thalassemia mutations and represents an important contribution to the knowledge regarding the molecular profile of beta thalassemia in our country

PURPOSE. To compare the effectiveness of posterior sub-Tenon's infusion (STi) and intravitreal injection (IVI) of triamcinolone acetonide (TA) for treatment of refractory diffuse diabetic macular edema.METHODS. Thirty-six phakic diabetic patients with refractory diffuse diabetic macular edema were prospectively enrolled. Patients randomly received either 40 mg STi or 4 mg IVI of TA. Comprehensive ophthalmic evaluation was performed at baseline and 1, 2, 4, 8 +/- 1, 12 +/- 2 and 24 +/- 2 weeks after treatment. Macular morphologic changes detected by optical coherence tomography and visual acuity, intraocular pressure, and lens status were evaluated.RESULTS. Twenty-eight patients (28 eyes) completed the 24-week study. Central macular thickness was significantly reduced in the IVI group when compared with the STi group at 2, 4, 8, 12, and 24 weeks after treatment (P < 0.01). Mean visual acuities (in logarithm of the minimum angle of resolution [logMAR]) at week-4, -8, and -12 follow-up examinations were significantly higher in the IVI group (0.74, 0.75, and 0.82, respectively) when compared with the STi group (0.88, 0.88, and 0.90, respectively; P < 0.01). A significant change from baseline in mean intraocular pressure (mm Hg) was seen at weeks 4 (+/- 3.21) and 8 (+/- 3.35) in STi the group (P < 0.01), and at week 8 (+/- 2.78) in the IVI group (P < 0.05). No patient had cataract progression during the study.CONCLUSIONS. Although the number of patients and length of follow-up in this preliminary study were limited, the changes in central macular thickness and visual acuity observed after treatment suggest that IVI TA may be more effective than STi for the management of refractory diffuse diabetic macular edema. Further studies are needed to confirm these preliminary findings.

Dois casos de displasia da valva tricúspide são relatados neste trabalho. Os cães foram avaliados devido à fraqueza e presença de ascite. em ambos os casos, o exame ecocardiográfico mostrou insuficiência tricúspide e, em um deles, a inserção dos folhetos da valva tricúspide encontrava-se deslocada para baixo do ventrículo direito, caracterizando a anomalia de Ebstein. A terapia medicamentosa para insuficiência cardíaca congestiva foi iniciada, mas um dos animais veio a óbito subitamente alguns dias após o diagnóstico. O outro cão, apesar de inicialmente ter apresentado melhora significativa do quadro clínico, apresentou morte súbita. A necropsia dos animais revelou dilatação atrioventricular direita e folhetos tricúspides espessados. As características clínicas, métodos de diagnóstico e terapia medicamentosa são discutidas neste artigo.

Nesta pesquisa foram utilizadas vinte fêmeas bovinas, sem patologias aparentes nas glândulas mamárias, em lactação, objetivando avaliar estruturas anatômicas das papilas mamárias. Quatro técnicas ultra-sonográficas foram avaliadas. Utilizou-se transdutor linear de 7,5 MHz para uso endoretal, na obtenção das imagens, padronizando-se o lado direito do animal para visualização das papilas craniais e caudais, em dois planos anatômicos (sagital e transversal). Os animais foram divididos em quatro grupos (G1, G2, G3, G4) que representaram as diferentes técnicas empregadas em momentos distintos (antes e após ordenha). Os resultados indicaram que entre as técnicas estudadas, as de exame direto e com uso de almofadada de silicone, foram as que apresentaram maior aplicabilidade, quando considerada a sua facilidade de uso na rotina com complementação do exame clinico. Entretanto, pólipos e cálculos lácteos tem sua extensão e localização convenientemente visibilizados mediante uso da técnica de pressão de liquido. Já a técnica de imersão em água, mostrou-se mais eficiente quanto à qualidade das imagens obtidas e na caracterização das estruturas anatômicas. O experimento realizado, traz subsídios anatomo-topográfico que irão contribuir com a qualidade do diagnóstico em pacientes que possam ter indicação cirúrgica (telotomia) e levanta questões que poderão ser respondidas conforme a casuística e a experiência consolidada do cirurgião.
