A PPCCIPS: a Política Pública da Coleta Complementar Itinerante e Programada de Sangue, sob a luz da teoria do ciclo da política pública

This study aimed to focus on aspects of public administration concerning the implementation of the public policy of complementary blood collection by the itinerant and scheduled PPCCIPS services either trough off local unity or mobile unit blood collection operations, which are managed by the State Institute of Hematology Arthur de Siqueira Cavalcanti - HEMORIO. The case study method was used in that public health institutional field, in search for a better understanding of responsibilities and management related to collection, serology, fractionation, storage and distribution of blood supply to almost all public hospitals and clinics, summed up to agreements with the single health system of the State of Rio de Janeiro. Bibliographic references, documentary and field data obtained through interviews and systematic observation in the public servants of HEMORIO workplaces, were treated by the analysis of the content method and the results of this research revealed the complexity of those services, and needs in outstanding aspects of infrastructure, equipment, logistics and personnel, which are critical for the achievement of the increased public collection of blood in the Rio de Janeiro State, endorsing the suggestions for the implementation of PPCCIPS in HEMORIO. The main point found in this research results concern the immanent ethical commitment of that public service personnel, including staff members and low ranking members as well, perceived due to a brief philosophical overlook on that personnel¿s attitudes. An important strategic aspect was revealed by the need for excellence of midia communications and education programs to implement the community involvement in the whole process. Final reflections point out that personnel posture is considered vital for the quality of the expected care of the technical activities and also for the quality of its final products release to the local public, fluminense, which is the irreplaceable human blood, and their derivatives. Despite the author¿s effort in this dissertation there is much more to be studied on that crucial theme.

Identificação do linfonodo-sentinela em pacientes com carcinoma de colo uterino invasor estádio I-B 1

Objetivo: determinar a viabilidade da identificação do linfonodo-sentinela em pacientes com câncer invasor de colo uterino estádio Ib1. Material e Métodos: 16 pacientes consecutivas com câncer de colo uterino agendadas para histerectomia radical com linfadenectomia pélvica bilateral realizaram estudo para detecção de linfonodo-sentinela. Onze pacientes injetaram 1 mCi de tecnécio 99 (99Tc) em quatro pontos do estroma superficial do colo uterino ao redor do tumor, às 12, 3, 6 e 9 h ( 16 horas antes da cirurgia ). No dia da cirurgia, as pacientes foram submetidas ao mapeamento linfático com gamma-probe e azul patente injetado nos mesmos pontos que o 99Tc.Cinco pacientes realizaram a detecção apenas com azul patente. Resultados: foi detectado pelo menos um (1 a 3 por paciente) linfonodo-sentinela em cada uma das 15 pacientes (93,7 %) que realizaram a técnica combinada.Foi detectado pelo menos 1 linfonodo-sentinela em 4 pacientes ( 80% )com azul patente apenas. A maioria dos linfonodos-sentinela foi localizada nas regiões: obturadora (37 %), ilíaca externa (22,2 %) e inter-ilíacas (18,5 %). Seis pacientes (40 %) tiveram linfonodos-sentinela bilaterais. Dos 27 linfonodos-sentinela detectados, 11 (40,7 %) foram detectados pelo corante, 9 (33,3%) pela radioatividade e 7 (26 %) pela radioatividade e corante. O índice de detecção intra-operatória com o gamma-probe foi de 90,9 % ( 11 pacientes ). Destes, 7 linfonodos foram azul e quente (31,8 %), 6 linfonodos foram apenas azuis (27,2 %) e 9 linfonodos foram apenas quentes (40,9 %). A sensibilidade, especificidade e valor preditivo negativo para a detecção do linfonodo-sentinela foram 100%, 85,7 % e 100 % respectivamente. Conclusão: A combinação do radiofármaco 99Tc e azul patente é efetiva na detecção do linfonodosentinela em câncer de colo uterino inicial.

5th BRICS Trade and Economic Research Network (TERN) meeting: the impact of mega agreements on BRICS

The BRICS TERN – BRICS Trade and Economics Research Network is a group of independent research institutes established four years ago by five think tanks from Brazil, Russia, India, China and South Africa. The main objective of the network is to study different aspects of trade and economic relations amongst these five countries. The purpose of the V BRICS TERN Meeting was to analyze and debate the effects of the negotiations of the Mega Agreements, mainly those initiated by the US and the EU, already in negotiation, to each of the BRICS Trade Policies. Both Mega Agreements were examined – the Trans Pacific Partnership (TPP) and the Transatlantic Trade and Investment Partnership (TTIP). The studies included the main impacts on trade flows and on the international trade rules system, respecting the perspective of each of the countries concerned. This workshop was an initiative of the Center for Global Trade and Investments (CGTI), a think-tank on International Trade held by FGV Sao Paulo School of Economics. Its main objective is the research on trade regulation, preferential trade agreements, trade and currency, trade and global value chains, through legal analysis and economic modelling. One of its main researches, now, is on the potential economic and legal impacts of the Mega Agreements on Brazil and WTO rules. This meeting was organized in March14, 2014, in Rio de Janeiro, in a perfect timing for introducing such issues in the international agenda, in advance of the 6th BRICS Summit scheduled to be held in Brazil in July 2014.

Prevalence of helicobacter pylori infection in advanced gastric carcinoma

There is substantial evidence that infection with Helicobacter pylori plays a role in the development of gastric cancer and that it is rarely found in gastric biopsy of atrophic gastritis and gastric cancer. On advanced gastric tumors, the bacteria can be lost from the stomach. Aims - To analyze the hypothesis that the prevalence of H.pylori in operated advanced gastric carcinomas and adjacent non-tumor tissues is high, comparing intestinal and diffuse tumors according to Lauren’s classifi cation. Methods - A prospective controlled study enrolled 56 patients from “Hospital Universitário”, Federal University of Rio Grande do Norte, Natal, RN, Brazil, with advanced gastric cancer, treated from February 2000 to March 2003. Immediately after partial gastrectomy, the resected stomach was opened and several mucosal biopsy samples were taken from the gastric tumor and from the adjacent mucosa within 4 cm distance from the tumor margin. Tissue sections were stained with hematoxylin and eosin. Lauren‘s classifi cation for gastric cancer was used, to analyse the prevalence of H. pylori in intestinal or diffuse carcinomas assessed by the urease rapid test, IgG by ELISA and Giemsa staining. H. pylori infected patients were treated with omeprazole, clarithromycin and amoxicillin for 7 days. Follow-up endoscopy and serology were performed 6 months after treatment to determine successful eradication of H. pylori in non-tumor tissue. Thereafter, follow-up endoscopies were scheduled annually. Chi-square and MacNemar tests with 0.05 signifi cance were used. Results - Thirty-four tumors (60.7%) were intestinal-type and 22 (39.3%) diffuse type carcinomas. In adjacent non-tumor gastric mucosa, chronic gastritis were found in 53 cases (94.6%) and atrophic mucosa in 36 patients (64.3%). All the patients with atrophic mucosa were H. pylori positive. When examined by Giemsa and urease test, H. pylori positive rate in tumor tissue of intestinal type carcinomas was higher than that in diffuse carcinomas. In tumor tissues, 34 (60.7%) H. pylori-positive in gastric carcinomas were detected by Giemsa method. H. pylori was observed in 30 of 56 cases (53.5%) in tissues 4 cm adjacent to tumors. This difference was not signifi cant. Eradication of H. pylori in non-tumor tissue of gastric remnant led to a complete negativity on the 12th postoperative month. Conclusions - The data confi rmed the hypothesis of a high prevalence of H. pylori in tumor tissue of gastric advanced carcinomas and in adjacent non-tumor mucosa of operated stomachs. The presence of H. pylori was predominant in the intestinal-type carcinoma

Estudo epidemiológico das parasitoses oculares na população de escolares da cidade de Natal-RN, Brasil

The objective of this study is to estimate the prevalence of Ocular Toxocariasis, Diffuse Unilateral Subacute Neuroretinitis (DUSN), Toxoplasma gondii infection and Ocular Toxoplasmosis in a student population in Natal-RN/Brazil and relate it to demographic, epidemiologic and socio-economic risk factors. The incidence of DUSN was observed in patients at the Federal University of Rio Grande do Norte Ophthalmology Service and the Prontoclinica de Olhos Ophthalmology clinic in Natal. In cases where a worm was found in the subretinal space, the result of treatment with photocoagulation using Green Laser (Eye Light ALCON) was evaluated in relation to final visual result. The sample was randomly selected among the schools of the four districts of Natal, according to the type of institution (public or private), its level (elementary or secondary), and study period (morning, afternoon or evening). The school population was studied from March to May, 2001. Initially, the students answered a questionnaire to evaluate demographic, epidemiologic and socio-economic risk factors. Afterwards, the following procedures were carried out: blood samples were taken for Toxoplasmosis (IgG, IgM) serology, hemogram, ophthalmological examination, consisting of clinical history, measurement of visual acuity, refraction under cycloplegia, biomicroscopy of the anterior segment and annexa, funduscopy and examination of extrinsic motility. The prevalence of Toxocariasis was 0.2% or 2 per one thousand students. The sample was insufficient to estimate the prevalence of DUSN. Seventy patients with DUSN diagnosis were examined from January, 2001 to January, 2003. A live worm was found in the subretinal space of all four patients in the acute phase, and these were treated with laser photocoagulation. After follow-up (average = 11.5 months), visual acuity improved in three eyes and remained unaltered in one eye. Worms were found in 22 of the 66 patients in the chronic phase, and these also were treated with laser photocoagulation. After a follow-up period of 13.1 months, on average, visual acuity improved in two of the patients, remained unchanged in 19 and worsened in one. The comparison of visual result before and after treatment was not statistically significant (p = 0.302). The diagnosis of DUSN in the acute phase, followed by prompt localization and destruction of the worm by photocoagulation, can improve the patient s vision. However, destruction of the worm by laser photocoagulation in eyes with DUSN in the chronic phase does not improve visual acuity. Seroprevalence for IgG was 46% (Confidence Interval CI 95%-42.9-49.2%) and for IgM it was 1.4% (CI 95% = 0.8-2.4%). The prevalence of ocular lesion was 1.15% (CI 95% = 0.6 - 2.0%). Socio-economic conditions were determinants in the prevalence of Systemic and Ocular Toxoplasmosis in the bivaried analysis and confirmed in the multivaried analysis (mother s scholarity illiterate/ OR = 2.9 and p < 0.001). The T. gondii infection prevalence, although high, was less than that found in studies performed in the South and Southeast of Brazil and that of Ocular Toxoplasmosis was completely discrepant, varying from 5 to 17 times less. Although important epidemiological variables such as owning a cat, drinking unfiltered water, and coming into contact with rivers or lakes showed an association in the preliminary analysis, they lost their influence when included in the logistic model. Future studies are scheduled to begin in March, 2004, in collaboration with other Brazilian and American universities in an attempt to discover the reason for these findings, as well as identifying the different strains of Toxoplasma gondii, and studying the sources of water utilized by the population of Natal Brazil

Segurança Alimentar e Controle de Qualidade: um estudo da implantação do Programa Alimentos Seguros em supermercados de bairro

This study aimed to analyze the percentage of compliance, related to the requirements of Practice, achieved by 23 supermarkets in neighborhood after the deployment of Food Insurance Program. For its development research methodology adopted was the application start and end of a check-list (tool-specific SBP) in 23 supermarkets, target of this study. After the deployment of PAS was made a comparative study where it was possible to see that these companies need to improve conditions related to food safety, because according to the study, none of the 23 supermarkets evaluated met the criteria recommended by the SBP to 100% of compliance for the items critical of the check-list. Only 04 of the 23 supermarkets were in the range of 80 to 90% of the overall percentage of compliance, representing only 17.3% of the sample. Most of the sample submitted in a regular situation, according to the methodology of Cardoso (2001). Of the 23 supermarkets studied, 03 supermarkets were classified as poor (13.04%), 13 as scheduled (56.52%) as good and 07 (30.43%). You can see improvements in a small part of the sample, but the decline in the percentage of compliance of 02 companies after working for the implementation of the program, showing lack of responsibility and commitment of companies which should have as its top priority to food safety that market

Uma contribuição à avaliação dos impactos da gestão de estoque na satisfação e fidelização pós-vendas de clientes de concessionárias de automóveis : um estudo empírico em Natal-RN

This paper aims to conduct a study to evaluate and measure the possible impact that the unavailability of spare parts can have on customer satisfaction for car dealerships in the post-sales. A theoretical-conceptual review on the subject of satisfaction and loyalty, on the backdrop of the reality of the automobile market, allowed the construction of a research tool dedicated to collect opinions of car owners, to allow an analysis empirical relationship between the availability of parts, repairs or scheduled service possible, and change or stay on the mark on the occasion of change of vehicle. 236 forms were applied to car owners in the city of Natal / RN. The results obtained in this survey allowed the identification of the unavailability of parts as a significant factor, among others, the motivation for the customer to switch brands. Collaterally, we could also conclude that the dynamics of change in marks, whatever its motivation, is reflected in the perceived positions of the different brands as the market share both in strictly quantitative terms and in terms of relative positioning, with significant changes in the ranking of consumer preferences for different brands available

Aplicação de tensoativos não iônicos na recuperação de fluidos de perfuração poliméricos

The drilling fluid used to assist in the drilling operation of oil wells, accumulates solids inherent in the formation as it is circulated in the well, interfering in the fluid performance during operation. It is discarded after use. The disposal of these fluids causes one of the most difficult environmental problems in the world. This study aims to promote liquid phase separation of drilling fluids, which have circulated in oil wells, and enable this recovered liquid to formulate a new fluid. For this, non-ionic surfactants were used in order to select the best outcome in phase separation. Five real water-based drilling fluids were utilized, which were collected directly from the fields of drilling oil wells, classified as polymeric fluids. The methodology used consisted in combining the fluid with surfactant and then subjecting it to a process of centrifugation or decantation. The decantating tests were scheduled through experimental planning 23 and 32, using as variables the percentage (%) of surfactant utilized and the stirring time in minutes. The surfactants used were ethoxylated nonylphenol and lauryl alcohol ethoxylated with different degrees of ethoxylation. Phase separation was monitored first by tests of stability, and subsequently by the height of the interface in beakers of 100 mL. The results showed that from the surfactants studied, the lauryl alcohol ethoxylated with 3 ethoxylation units has been the most effective in the phase separation process of the drilling fluids tested. The statistical tool used was of great industrial value regarding the programming phase separation in drilling fluids. In conclusion, the liquid phase separated using surfactant can be reused for a new formulation of drilling fluid with similar properties of a new fluid, assuring its efficiency. And in the resulting analysis it is also suggested that the adsorption is the mechanism that leads the phase separation, with surfactant adsorbing in the active solids

Avaliação da qualidade da atenção primária à saúde da criança no Rio Grande do Norte: visão das usuárias

The study aims to evaluate the quality of the work processes of the teams from the Family Health Strategy regarding the comprehensive health care for children, in the view of users in the state of Rio Grande do Norte. This is a cross-sectional observational evaluative research with quantitative approach. The primary data are part of the External Review from the Program of Improving Access and Quality of Primary Care (PMAQ) in 2012. 190 women were interviewed. The inclusion criteria was the presence in the clinic at the time of the survey, have attended the service in the last 12 months and be a mother or companion of a child up to two years old. A research protocol was developed in the dimensions of Growth and Development, Breastfeeding and nutrition, and health problems and its variables. The results revealed that mothers / companions who responded to the questionnaire 71% were aged between 18 and 35 years, 92.1% were literate, 96.3% had a monthly income and 62.6% received financial assistance from the government. As for the children, 39.4% were aged between 13 to 24 months. In promotion and prevention actions for children, 64.2% had consultation up to the 7th day of life, 91.1% underwent the screening test, 95.3% had a health handbook, 98.9% had a vaccine, 17.9% breastfed or breastfeed from 6 to 24 months. As for link and continuity of care, 86.8% of the children were accompanied by the same professional staff and 59.5% left with next consultation scheduled. In acute situations 42.4% of the children went to the health unit and 64% of these were attended. It is concluded that the actions involving prevention and health promotion of children in RN, are evaluated positively by the service users and meet the requirements of MS, as well as link and continuity of care. The weakness in access and reception of users is evident, indicating the need to adapt the service to the demand of health and planning actions to welcome all who seeks basic health unit-UBS

Does sealing endotracheal tube cuff pressure diminish the frequency of postoperative laryngotracheal complaints after nitrous oxide anesthesia?

Study Objectives: To study endotracheal tube (ETT) cuff pressures during nitrous oxide (N2O) anesthesia when the cuffs are inflated with air to achieve sealing pressure, and to evaluate the frequency of postoperative laryngotracheal complaints.Design: Prospective, randomized, blind study.Setting: Metropolitan teaching hospital.Patients: 50 ASA physical status I and II patients scheduled for elective abdominal surgery.Interventions: Patients received standard general anesthesia with 66% N2O in oxygen. In 25 patients, the ETT cuff was inflated with air to achieve a sealing pressure (P-seal group). In 25 patients, the ETT cuff was inflated with air to achieve a pressure of 25 cm H2O (P-25 group).Measurements and Main Results: ETT intracuff pressures were recorded before (control) and at 30, 60, 90, 120, and 150 minutes during N2O administration. We investigated the frequency and intensity of sore throat, hoarseness, and dysphagia in patients in the Post-Anesthesia Care Unit (PACU) and 24 hours following tracheal extubation. The cuff pressures in the P-seal group were significantly lower than in the P-25 group at all time points studied (p < 0.001), with a significant increase with time in both groups (p < 0.001). The cuff pressures exceeded the critical pressure of 30 cm H2O only after 90 minutes in the P-seal group and already by 30 minutes in the P-25 group. The frequency and intensity of sore throat, hoarseness, and dysphagia were similar in both groups in the PACU and 24 hours after tracheal extubation (p > 0.05).Conclusions: Minimum ETT sealing cuff pressure during N2O anesthesia did not prevent, but instead attenuated, the increase in cuff pressure and did not decrease postoperative laryngotracheal complaints.
