    Abstract Starting from the idea that “nation building” always begins with the destruction of the original nation, and that the stage of reconstruction does not take place, it is postulated that today this process is limited to the destruction of nations. This destruction is done with military intervention, as in the case of Irak, or without it, as in a large part of the world. Focusing on the pre-1952 Bolivian case, the author of this article offers a chronicle of that undercovered operation conceptualized as “destruction of nations.” He builds his chronicle with declassified documents from the United States Department of State, many of which were originally secret and remained so for a long time. A partir de la idea de que la "construcción de la nación” siempre comienza con la destrucción de la nación original, y que la etapa de la reconstrucción ya no se realiza, se postula que hoy por hoy ese proceso se limita a la destrucción de naciones. Esa destrucción se hace con la intervención militar, como en el caso de Irak, o sin ella, como en gran parte del planeta. Centrándose en el caso boliviano pre-1952, el autor de este trabajo ofrece una crónica de esa operacion encubierta conceptualizada como “destrucción de naciones”. La crónica está reconstruida con documentos desclasificados del Departamento de Estado de los Estados Unidos, muchos de los cuales fueron originalmente secretos y permanecieron así por mucho tiempo.

    Abstract: We report on a new measurement of the beam transverse single spin asymmetry in electron-proton elastic scattering, A_{⊥}^{ep}, at five beam energies from 315.1 to 1508.4 MeV and at a scattering angle of 30°<θ<40°. The covered Q^{2} values are 0.032, 0 ... ...

    Abstract We report on a new measurement of the beam transverse single spin asymmetry in electron-proton elastic scattering, A_{⊥}^{ep}, at five beam energies from 315.1 to 1508.4 MeV and at a scattering angle of 30°<θ<40°. The covered Q^{2} values are 0.032, 0.057, 0.082, 0.218, 0.613 (GeV/c)^{2}. The measurement clearly indicates significant inelastic contributions to the two-photon-exchange (TPE) amplitude in the low-Q^{2} kinematic region. No theoretical calculation is able to reproduce our result. Comparison with a calculation based on unitarity, which only takes into account elastic and πN inelastic intermediate states, suggests that there are other inelastic intermediate states such as ππN, KΛ, and ηN. Covering a wide energy range, our new high-precision data provide a benchmark to study those intermediate states.

    Title translation High incidence of hyperestrogenemia and dyslipidemia in a group of infertile men.
    Abstract The aim of this paper is to describe metabolic and endocrine alterations in the male, partners of infertile couples. One hundred and six consecutive men were taken in order to analyze their serum samples. Each serum sample was analyzed by duplicate for luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2), free-testosterone (T), 17 alpha-hydroxyprogesterone (17OHP), androstenedione (A), dehydroepiandrosterone-sulphate (DHEA-S), prolactin (PRL), insulin, glucose, total cholesterol and triclylcerides. The data analysis evidenced different metabolic or endocrine alterations in the group. A dysplipidemia incidence of 65% was found (isolated hypercholesterolemia, isolated triglyceridemia or both), where 80% of these patients were younger than 40 years. There was no correlation with obesity, overweight any endocrine alteration and the type of sperm alterations. There was a positive correlation between E2 and FSH (r = 0.67, p < 0.0001) in the group of 106 patients, which remained significant in the group of hyperestrogenic men (n = 27, r = 0.68, p < 0.0001), but not in men with normal serum estrogen levels (n = 79, r = 0.10, NS). Other alterations: obesity in 18%, overweight in 30.2%, diabetes mellitus 4.7%, glucose intolerance 15%, hypertension 26% (14/53), hypergonadotropic hypogonadism 3.8% (one of them with an Emty Sella syndrome). Unexpectedly only nine patients (8.4%) out of the 106 consecutive patients recluted did not have any of the metabolic or endodrine abnormalities here described. These are more significant since 83% of the patients are younger than 40 years. The most interesting non previously described finding was the positive correlation observed between E2 and FSH when estradiol levels exceeds 50 pg/mL.

    Title translation Hospital expenditures for five diseases of high economic impact.
    Abstract Objective: to identify by gender and age group, the hospital expenditures of the diseases that have the major economic impact at Instituto Mexicano del Seguro Social through using the diagnosis related groups (DRG) classification system and by estimating their associated costs.
    Methods: DRG system served to estimate hospital expenditures for five diseases: hypertension, type 2 diabetes, chronic renal failure, cervical cancer and HIV/AIDS. DRG allow for better estimation given that consider cost adjustment based on the amount of resources employed in the treatment of different episodes.
    Results: in the year 2002, 6.7 % of the hospital budget was assigned to the care of these five diseases. 42.6 % of the expenditures were allocated to patients aged 60 years and older and 22.3 % to patients from 50 to 59 years of age. Regarding diabetes mellitus and hypertension, care to patients over the age of 60 reached values of 55 % and 57 % of hospital expenditures respectively. Chronic renal failure and cervical cancer reached 60.5 % and 72.8 % of the expenditures, which were concentrated in patients aged 59 years or less; HIV/AIDS expenditures were distributed among patients from 20 to 50 years of age, the highest percentage (41.7 %) was in the group of 30 to 39 years of age.
    Conclusions: It is relevant to develop classification and information tools that consider the type of patients receiving hospital care, that are able to monitor changes due to the demographic and epidemiologic transition processes, and that allow for sensitive outcomes measurement. These tools will help in achieving an adequate financing and planning of health expenditures.

    Abstract This study assessed and quantified the effect of quality of care on death preventability, independent of social and biological variables. One hundred and eighty-one avoidable perinatal deaths (cases) were compared to 341 non-avoidable ones (controls). Judgement criteria on death preventability were based predominantly on compliance with explicit hospital medical care standards, determined by peer review. The overall perinatal mortality rate was 24.8 per 1000 births and could be reduced by 35% if all avoidable perinatal deaths were prevented. Sixteen per cent of the deaths presented structural and 31.2% process deficiencies; both predominated among avoidable perinatal deaths (35.4% vs 5.3%, p < 0.000; and 79.3% vs 5.9%, p < 0.000, respectively). Structural deficiencies increased the risk of an avoidable perinatal death eleven-fold (95% confidence interval (CI) 4.1, 26.9; p < 0.001) and process deficiencies eighty-eightfold (95% CI 37.2, 204.5, p < 0.001), after controlling for confounders. The strength of the association between quality of care and preventable perinatal mortality was estimated.

    Abstract Background: To study the sensitivity and specificity of the 50-g, 1-hour gestational glucose challenge test performed 1 to 2 hours after a non-standardized home breakfast in urban Mexican women by using three different gestational diabetes mellitus diagnostic criteria.
    Methods: Four hundred and forty-five consecutive women of 24-28 weeks gestation were studied. The glucose challenge test was performed in the fed state and a week later a fasting 100-g, 3-hours oral glucose tolerance test was carried out in all of them. Duplicate serum glucose concentrations were determined by a glucose-oxidase method. Sensitivity and specificity were calculated using three different diagnostic criteria for gestational diabetes mellitus.
    Results: The glucose challenge test performed as indicated, with a cutoff of 7.8 mmol/L, had 88-89% sensitivity and 85-87% specificity when using as diagnostic criteria those proposed by the National Diabetes Data Group and by Carpenter & Coustan; by using Sacks et al. criteria, the values were 82% and 88%, respectively. Considering only pregnant women > or = 25 years of age, the sensitivity increased to 92% with the National Diabetes Data Group criteria. Pregnant women < 25 years of age had significantly lower blood glucose values than those with age > or = 25 years during the glucose tolerance test.
    Conclusions: For the general group the sensitivity of the glucose challenge test performed 1 to 2 hours after breakfast was similar, based on the National Diabetes Data Group and the Carpenter & Coustan's diagnostic criteria for gestational diabetes mellitus. However, when pregnant women > or = 25 years of age were considered, the use of the former criteria yielded a slightly better sensitivity.
