Prevalence of Risk Factors for Coronary Artery Disease in the Brazilian State of Rio Grande do Sul

OBJECTIVE - To determine the risk factors prevalence for coronary artery disease in the State of Rio Grande do Sul, Brazil and to identify their relation with the age bracket. METHODS - We carried out an observational, cross-sectional study of 1,066 adults older than 20 years in the Brazilian State of Rio Grande do Sul. We investigated the risk factors: familial antecedents, systemic arterial hypertension, high levels of cholesterol and glycemia, overweight/obesity, smoking and sedentary lifestyle. A standardized questionnaire completed at the patients' dwellings by health agents were used; the data were stored in an EPI-INFO software database. The results were expressed with a 95% confidence interval. RESULTS - The sample composition was of 51.8% females. The risk factors prevalences were: 1) sedentary lifestyle 71.3%; 2) familial antecedents: 57.3%; 3) overweight/obesity (body mass index >25): 54.7%; 4) smokers: 33.9%; 5) hypertension: 31.6% (considering >140/90mmHg) and 14.4% (considering >160/95mmHg); 6) high glycemia (>126 mg/dL): 7%; 7) high cholesterol >240 mg/dL): 5.6%. CONCLUSION - The prevalence of the major risk factors for coronary artery disease in the Brazilian state of Rio Grande do Sul could be determined in a study that integrated public and private institutions.

Predictive factors of in-hospital mortality and of severe perioperative complications in myocardial revascularization surgery

OBJECTIVE: To investigate preoperative predictive factors of severe perioperative intercurrent events and in-hospital mortality in coronary artery bypass graft (CABG) surgery and to develop specific models of risk prediction for these events, mainly those that can undergo changes in the preoperative period. METHODS: We prospectively studied 453 patients who had undergone CABG. Factors independently associated with the events of interest were determined with multiple logistic regression and Cox proportional hazards regression model. RESULTS: The mortality rate was 11.3% (51/453), and 21.2% of the patients had 1 or more perioperative intercurrent events. In the final model, the following variables remained associated with the risk of intercurrent events: age ³ 70 years, female sex, hospitalization via SUS (Sistema Único de Saúde - the Brazilian public health system), cardiogenic shock, ischemia, and dependence on dialysis. Using multiple logistic regression for in-hospital mortality, the following variables participated in the model of risk prediction: age ³ 70 years, female sex, hospitalization via SUS, diabetes, renal dysfunction, and cardiogenic shock. According to the Cox regression model for death within the 7 days following surgery, the following variables remained associated with mortality: age ³ 70 years, female sex, cardiogenic shock, and hospitalization via SUS. CONCLUSION: The aspects linked to the structure of the Brazilian health system, such as factors of great impact on the results obtained, indicate that the events investigated also depend on factors that do not relate to the patient's intrinsic condition.

Acute myocardial infarction: clinical and epidemiological profile and factors associated with in-hospital death in the municipality of Rio de Janeiro

OBJECTIVE: To study the factors associated with the risk of in-hospital death in acute myocardial infarction in the Brazilian public health system in Rio de Janeiro, Brazil. METHODS: Sectional study of a sample with 391 randomly drawn medical records of the hospitalizations due to acute myocardial infarction recorded in the hospital information system in 1997. RESULTS: The diagnosis was confirmed in 91.7% of the cases; 61.5% males; age = 60.2 ± 2.4 years; delta time until hospitalization of 11 hours; 25.3% were diabetic; 58.1% were hypertensive; 82.6% were in Killip I class. In-hospital mortality was 20.6%. Thrombolysis was used in 19.5%; acetylsalicylic acid (ASA) 86.5%; beta-blockers 49%; angiotensin-converting enzyme (ACE) inhibitors 63.3%; calcium channel blockers 30.5%. Factors associated with increased death: age (61-80 years: OR=2.5; > 80 years: OR=9.6); Killip class (II: OR=1.9; III: OR=6; IV: OR=26.5); diabetes (OR=2.4); ventricular tachycardia (OR=8.5); ventricular fibrillation (OR=34); recurrent ischemia (OR=2.7). The use of ASA (OR=0.3), beta-blockers (OR=0.3), and ACE inhibitors (OR=0.4) was associated with a reduction in the chance of death. CONCLUSION: General lethality was high and some interventions of confirmed efficacy were underutilizated. The logistic model showed the beneficial effect of beta-blockers, and ACE inhibitors on the risk of in-hospital death.

La reconversion du quartier Gare/Crêt-Taconnet à Neuchâtel: réflexions sur la densification qualifiée

La reconversion des friches industrielles des secteurs de gare est prometteuse dans l'optique d'un développement urbain dense alternatif à l'étalement. Elles constituent en effet une réserve foncière centrale et bien desservie par les transports publics. La densification de ces terrains stratégiques ne pourra cependant freiner l'étalement urbain qu'à condition d'offrir un cadre de vie attractif pour l'habitat. Notre hypothèse est que l'engagement des pouvoirs publics est déterminant pour assurer cette densification qualifiée. Brown fields regeneration in railway station areas is particularly promising in the perspective of a compact urban development alternative to sprawl. They indeed constitute a central land stock which is well connected to public transportation networks. However, the densification of these strategic lands will make it possible to moderate urban sprawl only by providing an attractive environment for residential activities. Our hypothesis is that public authorities involvement is decisive to ensure such a qualified densification. Die Umnutzung von Industriebrachen in Bahnhofsarealen scheint viel versprechend im Hinblick auf eine Stadtentwicklung nach innen als Alternative zur Ausbreitung. Zentralgelegen, stellen diese ungenutzten Flächen eine strategische Bodenreserve dar, welche gut an das öffentliche Verkehrsmittelnetz angeschlossen ist. Ihre Verdichtung kann jedoch die Stadtausbreitung nur eindämmen unter der Bedingung, einen attraktiven Lebens- und Wohnraum zu bieten. Unsere Hypothese lautet, dass das Ausmass des Engagements der öffentlichen Hand bestimmend ist um diese qualitative Verdichtung sicherzustellen.

The feasibility of forecasting influenza epidemics in Cuba

A large influenza epidemic took place in Havana during the winter of 1988. The epidemiologic surveillance unit of the Pedro Kouri Institute of Tropical Medicine detected the begining of the epidemic wave. The Rvachev-Baroyan mathematical model of the geographic spread of an epidemic was used to forecast this epidemic under routine conditions of the public health system. The expected number of individuals who would attend outpatient services, because of influenza-like illness, was calculated and communicated to the health authorities within enough time to permit the introduction of available control measures. The approximate date of the epidemic peak, the daily expected number of individuals attending medical services, and the approximate time of the end of the epidemic wave were estimated. The prediction error was 12%. The model was sufficienty accurate to warrant its use as a pratical forecasting tool in the Cuban public health system.

Estudi epidemiològic de l'obesitat de 1r d'ESO de l'IES Pedraforca

Treball de recerca realitzat per una alumna d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l'any 2009. L'obesitat és una malaltia crònica que es caracteritza per un augment de la massa grassa i en conseqüència per un augment de pes. En el segle XXI aquesta malaltia, considerada epidèmia, està arribant a la població infantil i adolescent, i ha cridat l'atenció de totes les institucions de salut pública que estan lluitant per evitar aquesta alta prevalença d'obesitat i sobrepès. Aquest estudi confirma que existeix un alt percentatge d'obesitat i sobrepès en l'edat infantil i que està relacionat amb factors de risc (alguns modificables) que poden ser clau per a evitar aquesta malaltia. El mètode emprat és la realització d’un estudi epidemiològic transversal sobre una mostra de nens compresa en 39 individus de 12 a 14 anys d'edat. Es van determinar el pes, la talla, el plec bicipital i tricipital, l'ample del canell i del colze, a més de la realització d'una enquesta sobre hàbits alimentaris en l’esmorzar i dades socioculturals. L'obesitat i el sobrepès es van definir com resultats de IMC iguals als percentils 85 i 97 de les taules Orbegozo, respectivament. Els resultats van mostrar una prevalença de sobrepès i obesitat en la nostra mostra de població que va ser de 28,2%, la de només sobrepes del 15,4% i la de només obesitat del 12,8%. La prevalença d'obesitat és major en nens amb un 13,6% que en nenes 12,5% igual que el sobrepès. L'obesitat i sobrepès és major quan els estudis materns són inferiors als universitaris, també quan existeixen famílies amb 3 o més fills i quan es veu la TV més de 3 hores al dia.

Toxoplasmosis and mental retardation: report of a case-control study

A case-control study evaluating the association between mental retardation and toxoplasmosis was conducted among 845 school children in Belo Horizonte, MG, Brazil. Cases (450) were mentally retarded children attending a public school for special education. Controls (395) were children from the regular public school system. Clinical and anthropometric examinations and interviews were carried out to determine risk factors for toxoplasmosis and mental retardation. Diagnosis of Toxoplasma gondii infection was based upon an indirect immunofluorescent test (IFA); 55% of cases and 29% of controls were positive. The Relative Odds of mental retardation in children with positive serology was 3.0 (95% CI 2.2-4.0). Maternal exposure to cats and contact with soil were associated with an increased risk of mental retardation. Retinochoroiditis was fourfold more prevalent among cases than controls and was only diagnosed in T. gondii IFA positive participants. Congenital toxoplasmosis, in its subclinical form, appears to be an important component in the etiology of mental retardation, especially in high risk (lower socio-economic) groups. The population attributable risk was estimated as 6.0 - 9.0%, suggesting the amount of mental retardation associated with this infection.

L'oficina judicial a Catalunya: mitjà real d'una justícia eficaç pel ciutadà del segle XXI

En aquest estudi es pretenia assolir la pràctica d'un sistema que només s'ha plantejat teòricament, doncs l'experiència acumulada, ja abans de la reforma orgànica de 2003, parteix de la figura dels serveis comuns, amb un criteri d'eficiència, racionalitat i economia per invertir en l'Administració de justícia catalana. Assumir i donar resposta jurídica concreta a tots els reptes tècnics pot fer-se des d'una perspectiva dogmàtica, tot i que el temps transcorregut també permet advertir exigències pràctiques a l'àmbit de la dogmàtica processal, el context socio-cultural i, naturalment, les necessitats laborals. En aquest sentit, els objectius s'introdueixen cap a la garantia d'un apropament material, conceptual i quotidià de l'Administració de justícia al ciutadà, establert com a eix inextricable del sistema, tenint present la de vegades despesa incomprensible en una realitat històricament menystinguda i deficitària, malgrat l'esforç pressupostari fet els darrers anys que, malgrat tot, no ha evitat discordances greus per manca de racionalitat i eficiència en el consum diari dels operadors implicats. Es pretén aconseguir, per mitjà del nou sistema d'oficina judicial estructurat, un avenç efectiu i econòmic a l'estat de la Justícia al país, especialment envers la dilació dels tràmits, a més de reclamar reformes legals, de caire processal especialment, que no es prestin a mers paràmetres d'ajust formal, sinó que incideix substantivament en millores per altre part reclamades fa temps per la doctrina científica. S'han aconseguit les fites definides des del punt de vista teòric, així com s'ha afrontat tots el problemes conceptuals i hipòtesis pràctiques més significatives, establint pautes de resposta sota la prèvia determinació de les qüestions debatudes i els conflictes habituals que correspon enfrontar. D'aquesta manera, s'ha estudiat la normativa en presència i la jurisprudència que hi dona actualitat pràctica, sense oblidar la doctrina d'autors. S'ha repassat el funcionament existent a l'oficina judicial i les previsions de la mateixa en un futur immediat, remarcant les noves tecnologies en ús i projectades, de igual manera que les bondats i crítiques de tots els operador jurídics actuants.

Schistosomiasis control in the State of São Paulo

The program of schistosomiasis control for the State of São Paulo, where only low endemicity areas occur, is discussed in this paper. Inclusion of schistosomiasis among the diseases due to obligatory notification is considered as a measure of great importance. Accordingly the search for passive cases conducted by the public health system acquired major importance in the disease surveillance. As from 1981 to 1992 only 11% of the detected cases were considered as autochthonous. The main transmission areas are located at the Litoral and Paraiba Valley regions. In the period of time under analysis, the epidemiological surveillance data suggest a decrease in the morbidity and in the autochthony tendency in the State of São Paulo.

Obstetric analgesia and anesthesia in Switzerland in 2007

Introduction: The last twenty years has witnessed important changes in the field of obstetric analgesia and anesthesia. In 2007, we conducted a survey to obtain information regarding the clinical practice of obstetric anesthesia in our country. The main objective was to ascertain whether recent developments in obstetric anesthesia had been adequately implemented into current clinical practice. Methodology: A confidential questionnaire was sent to 391 identified wiss obstetric anesthetists. The questionnaire included 58 questions on 5 main topics: activity and organization of the obstetric unit, practice of labor analgesia, practice of anesthesia for caesarean section, prevention of aspiration syndrome, and pain treatment after cesarean section. Results: The response rate was 80% (311/391). 66% of the surveyed anesthetists worked in intermediate size obstetric units (500-1500 deliveries per year). An anesthetist was on site 24/24 hours in only 53% of the obstetric units. Epidural labor analgesia with low dose local anesthetics combined with opioids was used by 87% but only 30% used patient controlled epidural analgesia (PCEA). Spinal anesthesia was the first choice for elective and urgent cesarean section for 95% of the responders. Adequate prevention of aspiration syndrome was prescribed by 78%. After cesarean section, a multimodal analgesic regimen was prescribed by 74%. Conclusion: When comparing these results with those of the two previous Swiss surveys [1, 2], it clearly appears that Swiss obstetric anesthetists have progressively adapted their practice to current clinical recommendations. But this survey also revealed some insufficiencies: 1. Of the public health system: a. Insufficient number of obstetric anesthetists on site 24 hours/24. b. Lack of budget in some hospitals to purchase PCEA pumps. 2. Of individual medical practice: a. Frequent excessive dosage of hyperbaric bupivacaine during spinal anesthesia for cesarean section. b. Frequent use of cristalloid preload before spinal anesthesia for cesarean section. c. Frequent systematic use of opioids when inducing general anesthesia for cesarean section. d. Fentanyl as the first choice opioid during induction of general anesthesia for severe preeclampsia. In the future, wider and more systematic information campaigns by the mean of the Swiss Association of Obstetric Anesthesia (SAOA) should be able to correct these points.

Opening Education Beyond the Property Relation: From Commons to Communism

Open Education, and specifically the OER movement, seeks to provide universal access to knowledge, undermining the historical enclosure and the increasing privatisation of the public education system. In this paper we examine this aspiration by submitting the implicit theoretical assumptions of Open Education to the test of critical political economy. We acknowledge the Open Education movement's revolutionary potential but outline the inherent limitations of its current focus on the commons (property relations) rather than the social relations of capitalist production (wage work, the company) and because of this, argue that it will only achieve limited, rather than revolutionary, impact.

Guía metodológica para la elaboración de planes de igualdad en entidades del Sistema Sanitario Público de Andalucía (SSPA)

Currently equality plans are an effective tool to incorporate equal opportunities in human resource management of both companies and public administrations. They are also the appropriate mechanism to detect possible disparities and gender gaps in employment. Configured as an ordered set of actions and measures taken after a diagnosis of the situation and help organizations to promote equal treatment and opportunities between women and men in the workplace, and help eliminate discrimination based on sex. In this regard, the Directorate General of Health Planning and Innovation of the Ministry of Health, intends to promote and facilitate the development and implementation of equality plans in institutions and centers of the Andalusian Public Health System. This has raised the production and dissemination of a methodological guide that supports the design of equality plans in unison to allow both the completion of the monitoring process as the development and practical implementation of those plans.
