La Argentina y el Plan Marshall: promesas y realidades

El artículo analiza los intereses y prioridades de la política económica externa de los Estados Unidos y las complejas relaciones entre Washington y el gobierno de Buenos Aires en relación a la puesta en marcha del Plan Marshall de reconstrucción de Europa Occidental. La no participación de la Argentina en él dificultó su proceso de industrialización al restringir su comercio con el viejo continente e impedirle obtener las divisas necesarias para comprar en los EEUU, proveedor fundamental de los bienes que necesitaba.

The 1623 Plan for Global Governance: the obscure history of its reception

Abstract In the present article we analyze the characteristics and the reception of the first plan for global governance, the New Cyneas by Émeric Crucé. With this goal in mind, we examine the history of its readings and the possible influence on the Duke of Sully's project for European confederation, the case most often cited by historians of ideas. Our analysis takes into consideration the 17th century reception, the scant dissemination of the work and the possible causes of its limited impact. Our conclusions support, on the one hand, the novelty of Crucé's principal ideas, and on the other, their limited impact over the time with the exception of the period surrounding the creation of the League of Nations.

Distribución de recursos del Plan de Atención Básico con criterio de equidad, Bogotá 2002

OBJETIVO: Aplicar una técnica que oriente la distribución de recursos financieros del Plan de Atención Básico para acciones colectivas, según las condiciones de salud diferenciales. MÉTODOS: Se parte de la estimación previa de un índice global de salud mediante análisis de componentes principales, que jerarquiza las localidades de Bogotá, Colombia, en grupos según su estado de salud: "peor" estado, "intermedio" y "mejor" que los anteriores. Se aplica una técnica de mínimos cuadrados que minimice la diferencia entre el índice global de salud observado y un índice esperado con la inversión de tales recursos. RESULTADOS: Se obtiene la distribución de los recursos del Plan de Atención Básico para las veinte Localidades, destinando una cifra superior a la mediana Distrital en las Localidades con "peor" estado de salud. Además, se identifican las Localidades con déficit para el cubrimiento universal de la población de acuerdo con la destinación per cápita de dichos recursos. CONCLUSIÓN: La técnica utilizada pone en evidencia la diferencia en las condiciones de salud entre las localidades con "peor" estado de salud, con respecto a las localidades con "mejor" estado, a pesar de la incremento en la asignación del Plan de Atención Básico, indicando la necesidad de inversión social a nivel intersectorial en dichas localidades.

Spatial analysis of urban violence based on emergency room data

OBJECTIVE: To estimate the spatial intensity of urban violence events using wavelet-based methods and emergency room data. METHODS: Information on victims attended at the emergency room of a public hospital in the city of São Paulo, Southeastern Brazil, from January 1, 2002 to January 11, 2003 were obtained from hospital records. The spatial distribution of 3,540 events was recorded and a uniform random procedure was used to allocate records with incomplete addresses. Point processes and wavelet analysis technique were used to estimate the spatial intensity, defined as the expected number of events by unit area. RESULTS: Of all georeferenced points, 59% were accidents and 40% were assaults. There is a non-homogeneous spatial distribution of the events with high concentration in two districts and three large avenues in the southern area of the city of São Paulo. CONCLUSIONS: Hospital records combined with methodological tools to estimate intensity of events are useful to study urban violence. The wavelet analysis is useful in the computation of the expected number of events and their respective confidence bands for any sub-region and, consequently, in the specification of risk estimates that could be used in decision-making processes for public policies.

Screening for pulmonary tuberculosis in Teresópolis, RJ, Brazil: the search for respiratory symptomatic patients in emergency service of "Hospital das Clínicas de Teresópolis Costantino Ottaviano, Fundação Educacional Serra dos Órgãos"

The aim of the present study was to investigate the detection percentage of tuberculosis among patients that are respiratory symptomatic (TB suspects). In this work, we present the preliminary results of research carried out at "Hospital das Clínicas de Teresópolis Costantino Ottaviano da Fundação Educacional Serra dos Órgãos (FESO)" from November 2003 to April 2004. Among the 40 respiratory symptomatic individuals identified and referred to the Tuberculosis Control Program in Teresópolis, two (5.0%) were characterized as smear-positive. These results confirm reports in the literature and underscore the need for and importance of this strategy.

Ten years of a hantavirus disease emergency in the Federal District, Brazil

Abstract: INTRODUCTION: Hantavirus diseases are emerging human diseases caused by Hantavirus spp. of the Bunnyaviridae family. Hantavirus pulmonary syndrome (HPS) has been detected in the Federal District (DF) of Brazil since 2004. Among the 27 Brazilian Federal Units, DF has the highest fatality rate. More than 10 years have already passed since then, with confirmation of cases caused by the Araraquara and Paranoa species. The reservoir is Necromys lasiurus. METHODS: Local surveillance data of the confirmed cases were analyzed, including age, sex, month and year of occurrence, clinical symptoms, syndromes and outcomes, and probable transmission place (PTP). The cases were mainly confirmed by IgM detection with a capture enzyme immunoassay. The cases were classified as autochthonous if PTPs were in the DF area. RESULTS: From 2004 to 2013, in the DF, 126 cases of hantavirus were confirmed, and the cumulative incidence was 5.0 per 100,000 inhabitants. The occurrence of cases was predominantly from April to August. At least 75% of the cases were autochthonous. Acute respiratory failure was reported in 47.5% of cases, and the fatality rate was 40%. CONCLUSIONS: In the DF, the cumulative incidence of HPS was one of the highest worldwide. A seasonal pattern of hantavirus disease in the dry season is clear. There was a high frequency of severe clinical signals and symptoms as well as a high fatality rate. For the near future, visitors and inhabitants of DF rural areas, particularly male adults, should receive continuous education about hantavirus transmission and prevention.

Hypertonic/hyperoncotic solution in hypovolemic patients: experience in the emergency room

Hypertonic solutions have been studied extensively in the treatment of hypovolemic shock, both in experimental and clinical models. Safety, efficacy, and long-term effects on animals and patients have been evaluated. The present article reviews indications, safety, mortality rates, and outcome in patients with hemorrhagic hypovolemic shock who were treated after admission with a hypertonic/hyperoncotic solution under strict observation in the emergency room.

Suicide attempts and substance use in an emergency room sample

OBJECTIVE: Describe suicide attempts assisted in an emergency room (ER) and acute substance consumption or dependence on these individuals. METHODS: Descriptive epidemiologic study was carried out during one year, evaluating suicide attempts assisted at Embu das Artes ER, São Paulo, Brazil. Patients were scheduled to a non structured psychiatric interview. Main outcomes measures were: socio demographic data, suicide attempt method, drugs or alcohol acute use in the six hours prior to attempt, patients with ICD-10 substance dependence diagnosis. The descriptive analyses and chi-square test (p < 0.05) were used to verify associations between the variables studied. RESULTS: sample was formed of 80 patients, mean age of 26.9 years (SD = 8.91), predominantly female (72.5%) and 21.2% adolescents. Most suicide attempts were made through medicine ingestion (62.5%). Approximately 21.2% and 7.5% related to have used alcohol and an illicit drug respectively within 6 hours prior to attempt and 10% were found to be substance dependent. All substance dependents had attempted suicide previously (p-value = 0.4). There was a significant association between suicide attempt through medicine ingestion and psychiatric treatment history (p = 0.02). CONCLUSION: More national studies are necessary to consider the role of alcohol and drug in suicide attempts assisted in ER, especially in chemical dependents whose suicidal behavior is relevant.

Hormonal, metabolic and nutritional alterations in smokers: emergency for smoking abstinence

OBJECTIVE: To evaluate the biochemical and nutritional status of smokers in treatment for smoking cessation and its association with anthropometric parameters. METHODS: This is a cross-sectional study with convenience sample. Adult smokers were assessed at the start of treatment in the Interdisciplinary Center for Tobacco Research and Intervention of the University Hospital of the Federal University of Juiz de Fora (CIPIT/HU-UFJF). We evaluated the body mass index (BMI), conicity index (CI); waist circumference (WC), percentage of body fat (%BF), fasting glycemia, cortisol, insulin, total cholesterol (TC), LDL-c, HDL-c, triglycerides (TG) and metabolic syndrome (MS). RESULTS: Most participants (52.2%) had MS and high cardiovascular risk. The fasting glycemia was abnormal in 30.4%. There was a significant positive correlation between BMI and WC (r = 0.90; p = 0.0001), %BF (r = 0.79; p = 0.0001), CI (r = 0.65; p = 0.0001), glycemia (r = 0.42; p = 0.04) and TG (r = 0.47; p = 0.002). The CI presented positive correction with insulin (r = 0.60; p = 0.001), glycemia (r = 0.55; p = 0.007), TG (r = 0.54; p = 0.008) and %BF (r = 0.43; p = 0.004). Patients with longer duration of smoking had a higher risk of developing MS (OR = 9.6, p = 0.016). CONCLUSION: The smokers evaluated had increased risk for developing MS, especially those with longer duration of smoking, requiring urgent smoking cessation.

Therapeutic approach to patients complaining of high blood pressure in a cardiological emergency room

OBJECTIVE: To evaluate the management of patients complaining of high blood pressure (BP) in a cardiological emergency room. METHODS: Patients referred to the cardiological emergency room with the main complaint of high blood pressure were consecutively selected. The prescriptions and the choice of antihypertensive drugs were assessed. The classification of these patients as hypertensive emergencies or pseudoemergencies, according to the physician who provided initial care, was recorded. RESULTS: From a total of 858 patients presenting to the emergency room, 80 (9.3%) complained of high BP, and 61 (76.3%) received antihypertensive drugs. Sublingual nifedipine was the most commonly used drug (59%). One patient received intravenous medication, one patient was hospitalized and 6 patients (7.5%) were classified as hypertensive emergencies or pseudoemergencies. CONCLUSION: High BP could seldom be classified as a hypertensive emergency or pseudoemergency, even though it was a frequent complaint (9.3% of visits). Currently, the therapeutic approach is not recommended, even in specialized clinics.

Chest pain in the emergency room. Importance of a systematic approach

OBJECTIVE: To evaluate the efficiency of a systematic diagnostic approach in patients with chest pain in the emergency room in relation to the diagnosis of acute coronary syndrome (ACS) and the rate of hospitalization in high-cost units. METHODS: One thousand and three consecutive patients with chest pain were screened according to a pre-established process of diagnostic investigation based on the pre-test probability of ACS determinate by chest pain type and ECG changes. RESULTS: Of the 1003 patients, 224 were immediately discharged home because of no suspicion of ACS (route 5) and 119 were immediately transferred to the coronary care united because of ST elevation or left bundle-branch block (LBBB) (route 1) (74% of these had a final diagnosis of acute myocardial infarction [AMI]). Of the 660 patients that remained in the emergency room under observation, 77 (12%) had AMI without ST segment elevation and 202 (31%) had unstable angina (UA). In route 2 (high probability of ACS) 17% of patients had AMI and 43% had UA, whereas in route 3 (low probability) 2% had AMI and 7 % had UA. The admission ECG has been confirmed as a poor sensitivity test for the diagnosis of AMI ( 49%), with a positive predictive value considered only satisfactory (79%). CONCLUSION: A systematic diagnostic strategy, as used in this study, is essential in managing patients with chest pain in the emergency room in order to obtain high diagnostic accuracy, lower cost, and optimization of the use of coronary care unit beds.
