Regímenes Internacionales y Derechos Humanos. La incidencia del sistema interamericano de protección en la legislación y jurisprudencia argentinas. International Regimes and Human Rights. The incidence of inter-American system in Argentine law and jurisprudence.

El nuevo escenario internacional produce lo que se ha dado en caracterizar como la globalización del derecho, especialmente en el ámbito de los derechos humanos. En este contexto se analiza la incidencia del Sistema Interamericano de protección de los Derechos Humanos con especial énfasis en el derecho de la información, desde la optica del derecho interno. Nos preguntamos acerca de cómo se presenta la tensión entre la lógica estatal con su rasgo de afirmación en la soberanía y monopolio en la creación de la jurisdicción doméstica, con la doctrina del derecho internacional de los derechos humanos, que consecuentemente conduce hacia una globalización jurídica de estos temas. Esto refleja un debilitamiento en el monopolio de creación y aplicación del derecho por parte de los Estados. A partir de este dato del escenario internacional buscamos determinar la incidencia de los informes de la Comisión Interamericana de Derechos Humanos y los pronunciamientos de la Corte Interamericana en materia de derecho de la información y su influencia en la jurisprudencia y creación de legislación en nuestro país. The new internacional scenario produces wtah has come to be characterized as the globalization of law, especially in the field of the human rights. In this context we analyze the impact of the Inter-American system of human Rights, whit particular emphasis on media law in domestic law

Incidence and Predictors of Cardiovascular Complications and Death after Vascular Surgery

AbstractBackground:Patients undergoing arterial vascular surgery are considered at increased risk for post-operative complications.Objective:To assess the incidence and predictors of complications and death, as well as the performance of two models of risk stratification, in vascular surgery.Methods:This study determined the incidence of cardiovascular complications and deaths within 30 days from surgery in adults. Univariate comparison and logistic regression assessed the risk factors associated with the outcomes, and the receiver operating characteristic (ROC) curve assessed the discriminatory capacity of the revised cardiac risk index (RCRI) and vascular study group of New England cardiac risk index (VSG-CRI).Results:141 patients (mean age, 66 years; 65% men) underwent the following surgeries: carotid (15); lower limbs (65); abdominal aorta (56); and others (5). Cardiovascular complications and death occurred within 30 days in 28 (19.9%) and 20 (14.2%) patients, respectively. The risk predictors were: age, obesity, stroke, poor functional capacity, altered scintigraphy, surgery of the aorta, and troponin change. The scores RCRI and VSG-CRI had area under the curve of 0.635 and 0.639 for early cardiovascular complications, and 0.562 and 0.610 for death in 30 days.Conclusion:In this small and selected group of patients undergoing arterial vascular surgery, the incidence of adverse events was elevated. The risk assessment indices RCRI and VSG-CRI did not perform well for complications within 30 days.

Pneumocystis carinii: its incidence in rodents and enhancement of the infection by corticosteroids

A survey was made on the incidence of Pneumocystis carinii in 361 rodents including sewer rats, albino rats, albino mice, guinea-pigs and rabbits. P. carinii was found in 4 of the 215 Rattus norvegicus examined (1,8%). These results accord with recent observations but disagree with investigations made by the researchers who first studied this parasite in the past when high indexes of infection were found. However, in 20 albino rats treated with corticosteroids (betamethazone) we found 8 positive (40%) and in 20 albino mice treated by the same way, 9 were positive for P. carinii (45%). These results confirm the opportunistic character of P. carinii in rodents already well demonstrated in man.

Analyse rétrospective de la prise en charge du cancer ovarien au Centre Hospitalier Universitaire Vaudois

Introduction:¦L'incidence annuelle du cancer de l'ovaire en Suisse est de 600 cas, il touche principalement les femmes âgées de plus de 60 ans. Le cancer de l'ovaire est aujourd'hui la 1ère cause de mortalité par cancer gynécologique chez la femme. Le but de notre recherche, est de créer une base de données de toutes les¦patientes atteintes d'un cancer de l'ovaire et hospitalisées au CHUV pour la prise en charge de leur maladie.¦Cette étude rétrospective monocentrique nous permettra en premier lieu d'analyser les caractéristiques de¦cette tumeur présentées par les patientes, les traitements instaurés pour traiter ce cancer et les taux de¦récidives et de survie des patientes en fonction de ces variables.¦Méthodologie:¦Analyse rétrospective de 147 patientes diagnostiquées d'un cancer de l'ovaire et hospitalisées au CHUV entre¦septembre 2001 et mars 2010 pour la prise en charge de leur tumeur ovarienne. Utilisation du programme informatique ARCHIMED qui contient les dossiers médicaux de toutes les patientes inclues dans l'étude et création de 2 bases des données. La 1ère base de données regroupe l'ensemble des patientes de l'étude y¦compris les tumeurs type borderline, la 2ème base de données concerne uniquement les patientes ayant récidivé de leur tumeur. Les tumeurs bénignes ont été exclues de l'étude.¦Résultats:¦La probabilitéde survie à 1 an chez les patientes avec un cancer de l'ovaire, tous stades FIGO et prises en¦charge confondus, hospitalisées au CHUV est de 88,04% (95% CI = 0.7981-­‐0.9306), à 3 ans la probabilité de survie est de 70,4% (95% CI = 0.5864-­‐0.7936), et à plus de 5 ans, elle est de 60% (95% CI = 0.4315-­‐0.6859).¦Nous avons comparé le taux de survie en fonction du stade FIGO de la tumeur ovarienne et nous avons observé une différence significative de survie entre les stades FIGO précoces et les stades avancés (Pvaleur=¦0.0161).¦En plus d'une intervention chirurgicale, les patientes atteintes d'un cancer de l'ovaire sont normalement traitées par une chimiothérapie. Dans notre étude, 70 patientes ont bénéficié d'une chimiothérapie; un¦traitement adjuvant a été donné dans 78 % des cas (N = 55), un traitement néoadjuvant a été administré chez 22% des patientes (N=15). Le type combiné carboplatine-­‐taxane est la chimiothérapie la plus fréquente (75%). Au total sur l'étude, 66 patientes sur les 147 (44%) ont récidivé de leur tumeur. En ce qui¦concerne leur prise en charge, 46% des patientes ont reçu une chimiothérapie unique comme du gemzar, cealyx ou taxotère après leur récidive. Une cytoréduction secondaire a également été effectuée chez 33% de ces patientes ayant une récidive. Nous avons également étudié l'intervalle de temps entre la date de la¦récidive et celle du décès. Parmi les 28 patientes décédées chez les récidives, 10 d'entre-­‐elles (36%) ont survécu moins d'un an une fois la récidive diagnostiquée, 8 (28%) patientes ont survécu jusqu'à 2 ans, et¦les 10 (36%) autres patientes ont survécu de 2 à 5 ans. En ce qui concerne le taux de mortalité; 39 patientes sur les 147 étudiées sont décédées pendant la période d'observation, soit 26% des cas. La tumeur¦type borderline, présente une prolifération épithéliale atypique sans invasion dans le stroma et représente¦10 à 20% de toutes les tumeurs ovariennes. Dans notre étude, 41 patientes sont porteuses de cette tumeur¦(28%) et la moyenne d'âge est de 49 ans. En ce qui concerne leur prise en charge, l'intervention chirurgicale¦la plus fréquente, soit 23% des cas, est l'annexectomie unilatérale, qui reste une attitude conservative pour¦ces patientes désirant préserver leur fertilité. 6 patientes présentant ce type de tumeur ont récidivé, soit 14% des cas, avec une progression pelvienne, et 3 de ces 6 patientes sont décédées. Dans notre analyse, on observe que la probabilité de vivre plus longtemps que 1an pour les patientes ayant une tumeur borderline est de 93,8% (95% CI= 0.6323-­‐ 0.9910), à 3 ans elle est également de 93,8% (95% CI = 0.6323-­‐0.9910) et à 5 ans elle est de 78,1% (95% CI = 0.3171-­‐0.9483). Nous n'avons pas observé de¦différence de survie dans notre étude entre les patientes présentant une tumeur borderline et le « non‐borderline ». (Pvaleur=0.3301)

Ecology of sandflies Diptera: Psychodidae) in a restricted focus of cutaneous leishmaniasis in Northern Venezuela: IV. Sandfly monthly fluctuation and leishmaniasis incidence relationship

An attempt has been made to correlate the monthly incidence of human leishmaniasis with the temporal distribution of sandfly species at San Esteban, Northern Venezuela. Upon statistical analysis, the seasonal fluctuation of L. ovallesi population correlated strongly with the human disease, while the dynamics of L. panamensis, generally believed to be the vector in the Central area of the country, showed only a very weak correlation. These findings support the hypothesis that L. panamensis might not be the main or unique species responsible for the transmission in this area and that L. ovallesi and additionally L. olmeca bicolor might be involved in the epidemiology of the disease.

A contribution to the study of simulium and Culicoides of Rio de Janeiro: monthly incidence and biting activity

During March 1984 to February 1985, we captured simuliids and biting midges in the National Park of Tijuca, Rio de Janeiro. A study on monthly incidence and biting activity and their correlation to air temperature, relative humidity, and rainfall was made.

Ecologic correlations of selected food groups with disease incidence and mortality in Switzerland.

Background: There is little information regarding the impact of diet on disease incidence and mortality in Switzerland. We assessed ecologic correlations between food availability and disease.Methods: In this ecologic study for the period 1970-2009, food availability was measured using the food balance sheets of the Food and Agriculture Organization of the United Nations. Standardized mortality rates (SMRs) were obtained from the Swiss Federal Office of Statistics. Cancer incidence data were obtained from the World Health Organization Health For All database and the Vaud Cancer Registry. Associations between food availability and mortality/incidence were assessed at lags 0, 5, 10, and 15 years by multivariate regression adjusted for total caloric intake.Results: Alcoholic beverages and fruit availability were positively associated, and fish availability was inversely associated, with SMRs for cardiovascular diseases. Animal products, meat, and animal fats were positively associated with the SMR for ischemic heart disease only. For cancer, the results of analysis using SMRs and incidence rates were contradictory. Alcoholic beverages and fruits were positively associated with SMRs for all cancer but inversely associated with all-cancer incidence rates. Similar findings were obtained for all other foods except vegetables, which were weakly inversely associated with SMRs and incidence rates. Use of a 15-year lag reversed the associations with animal and vegetal products, weakened the association with alcohol and fruits, and strengthened the association with fish.Conclusions: Ecologic associations between food availability and disease vary considerably on the basis of whether mortality or incidence rates are used in the analysis. Great care is thus necessary when interpreting our results.

Disseminated M. avium complex infection in the Swiss HIV Cohort Study: declining incidence, improved prognosis and discontinuation of maintenance therapy.

Introduction of potent antiretroviral combination therapy (ART) has reduced overall morbidity and mortality amongst HIV-infected adults. Some prophylactic regimes against opportunistic infections can be discontinued in patients under successful ART. (1) The influence of the availability of ART on incidence and mortality of disseminated M. avium Complex infection (MAC). (2) The safety of discontinuation of maintenance therapy against MAC in patients on ART. The Swiss HIV-Cohort Study, a prospective multicentre study of HIV-infected adults. Patients with a nadir CD4 count below 50 cells/mm3 were considered at risk for MAC and contributed to total follow-up time for calculating the incidence. Survival analysis was performed by using Kaplan Meier and Cox proportional hazards methods. Safety of discontinuation of maintenance therapy was evaluated by review of the medical notes. 398 patients were diagnosed with MAC from 1990 to 1999. 350 had a previous CD4 count below 50 cells/mm3. A total of 3208 patients had a nadir CD4 count of less than 50 cells/mm3 during the study period and contributed to a total follow-up of 6004 person-years. The incidence over the whole study period was 5.8 events per 100 person-years. In the time period of available ART the incidence of MAC was significantly reduced (1.4 versus 8.8 events per 100 person-years, p < 0.001). Being diagnosed after 1995 was the most powerful predictor of better survival (adjusted hazard ratio for death: 0.27; p < 0.001). None of 24 patients discontinuing maintenance therapy while on ART experienced recurrence of MAC during a total follow-up of 56.6 person-years (upper 95% confidence limit 5.3 per 100 person-years). Introducing ART has markedly reduced the risk of MAC for HIV-infected individuals with a history of very low CD4 counts. Survival after diagnosis of MAC has improved after ART became available. In patients responding to ART, discontinuation of maintenance therapy against M. avium may be safe.

Unusual spread of a penicillin-susceptible methicillin-resistant Staphylococcus aureus clone in a geographic area of low incidence.

We describe the unusual spread of a penicillin-susceptible methicillin-resistant Staphylococcus aureus (MRSA) clone in hospitals in western Switzerland, where the incidence of MRSA is usually low. During a 2-year period, this clone had been responsible for several outbreaks and had been isolated from &gt;156 persons in 21 institutions. Molecular typing by pulsed-field gel electrophoresis (PFGE) demonstrated that all of these isolates belonged to the same clone. In 1 of the outbreaks, involving 30 cases, the clone was responsible for at least 17 secondary cases. In contrast, during the period of the latter outbreak, 9 other patients harboring different MRSA strains, as assessed by PFGE, were hospitalized in the same wards, but no secondary cases occurred. These observations suggest that this clone, compared with other MRSA strains, had some intrinsic factor(s) that contributed to its ability to disseminate and could thus be considered epidemic.

Tuberculosis in HIV-negative and HIV-infected patients in a low-incidence country: clinical characteristics and treatment outcomes.

BACKGROUND: In Switzerland and other developed countries, the number of tuberculosis (TB) cases has been decreasing for decades, but HIV-infected patients and migrants remain risk groups. The aim of this study was to compare characteristics of TB in HIV-negative and HIV-infected patients diagnosed in Switzerland, and between coinfected patients enrolled and not enrolled in the national Swiss HIV Cohort Study (SHCS). METHODS AND FINDINGS: All patients diagnosed with culture-confirmed TB in the SHCS and a random sample of culture-confirmed cases reported to the national TB registry 2000-2008 were included. Outcomes were assessed in HIV-infected patients and considered successful in case of cure or treatment completion. Ninety-three SHCS patients and 288 patients selected randomly from 4221 registered patients were analyzed. The registry sample included 10 (3.5%) coinfected patients not enrolled in the SHCS: the estimated number of HIV-infected patients not enrolled in the SHCS but reported to the registry 2000-2008 was 146 (95% CI 122-173). Coinfected patients were more likely to be from sub-Saharan Africa (51.5% versus 15.8%, P<0.0001) and to present disseminated disease (23.9% vs. 3.4%, P<0.0001) than HIV-negative patients. Coinfected patients not enrolled in the SHCS were asylum seekers or migrant workers, with lower CD4 cell counts at TB diagnosis (median CD4 count 79 cells/µL compared to 149 cells/µL among SHCS patients, P = 0.07). There were 6 patients (60.0%) with successful outcomes compared to 82 (88.2%) patients in the SHCS (P = 0.023). CONCLUSIONS: The clinical presentation of coinfected patients differed from HIV-negative TB patients. The number of HIV-infected patients diagnosed with TB outside the SHCS is similar to the number diagnosed within the cohort but outcomes are poorer in patients not followed up in the national cohort. Special efforts are required to address the needs of this vulnerable population.

Survival and Molting Incidence after Heat and Cold Shocks in Panstrongylus megistus Burmeister

Survival and molting incidence were studied after heat (40°C) and cold (0°C) shocks in specimens of Panstrongylus megistus with the aim of establishing its response to temperature stress under laboratory rearing conditions and to understand occasional changes in the biological characteristics of specimens captured in nature. The response to the thermal shocks was found to vary as a function of the temperature and duration of the shock, developmental phase and sex of the specimens, and in certain cases, the insect habit and nourishment conditions. P. megistus specimens were found to be less resistant to the heat shock assay than Triatoma infestans, another reduviid species. The short cold shock affected survival of P. megistus more than did the heat shock, survival of fully-nourished specimens being preferential. The response of adults to the short cold shock was affected by sex, males being generally less resistant. The insect sylvatic habit was found to seldom affect the thermal shock response established for specimens with domestic habit. A decrease in molting frequency and sometimes a slowdown of the molting rate were found after the short heat and cold shocks, possibly promoted by change in hormonal balance, and differing from patterns reported for T. infestans. The results indicate that no generalization should be made for different reduviid species in terms of the effects of temperature shocks.

Incidence of second sarcomas: a cancer registry-based study.

BACKGROUND: In high-quality cancer registration systems, about one in eight incident cancers are second primary cancers. This is due to a combination of careful diagnostic ascertainment, shared genetic determinants, shared exposure to environmental factors and consequences of treatment for first cancer. METHODS: We used data derived from the Swiss population-based cancer Registries of Vaud and Neuchâtel, including 885,000 inhabitants. RESULTS: Among 107,238 (52% males) first cancers occurring between 1976 and 2010, a total of 126 second sarcomas were observed through active and passive follow-up versus 68.2 expected, corresponding to a standardized incidence ratio (SIR) of 1.85 (95 % CI 1.5-2.2). Significant excess sarcoma risks were observed after skin melanoma (SIR = 3.0), breast cancer (2.2), corpus uteri (2.7), testicular (7.5), thyroid cancer (4.2), Hodgkin lymphoma (5.7) and leukemias (4.0). For breast cancer, the SIR was 3.4 ≥5 years after sarcoma diagnosis. CONCLUSIONS: The common denominator of these neoplasms is the utilization of radiotherapy in their management. Some sarcomas following breast cancer may be due to shared genetic components (i.e., in the Li-Fraumeni syndrome), as well as possibly to shared environmental factors, with sarcomas, including overweight, selected dietary and reproductive factors which are, however, too little defined for any quantitative risk assessment.

Age-specific incidence of all neoplasms after colorectal cancer.

PURPOSE: Patients diagnosed with a specific neoplasm tend to have a subsequent excess risk of the same neoplasm. The age incidence of a second neoplasm at the same site is approximately constant with age, and consequently the relative risk is greater at younger age. It is unclear whether such a line of reasoning can be extended from a specific neoplasm to the incidence of all neoplasms in subjects diagnosed with a defined neoplasm. METHODS: We considered the age-specific incidence of all non-hormone-related epithelial neoplasms after a first primary colorectal cancer (n = 9542) in the Vaud Cancer Registry data set. RESULTS: In subjects with a previous colorectal cancer, the incidence rate of all other epithelial non-hormone-related cancers was stable around 800 per 100,000 between age 30 and 60 years, and rose only about twofold to reach 1685 at age 70 to 79 years and 1826 per 100,000 at age 80 years or older. After excluding synchronous cancers, the rise was only about 1.5-fold, that is, from about 700 to 1000. In the general population, the incidence rate of all epithelial non-hormone-related cancers was 29 per 100,000 at age 30 to 39 years, and rose 30-fold to 883 per 100,000 at age 70 to 79 years. Excluding colorectal cancers, the rise of all non-hormone-related cancers was from 360 per 100,000 at age 40 to 49 years to 940 at age 70 to 79 years after colorectal cancer, and from 90 to 636 per 100,000 in the general population (i.e., 2.6- vs. 7.1-fold). CONCLUSIONS: The rise of incidence with age of all epithelial non-hormone-related second cancers after colorectal cancer is much smaller than in the general population. This can possibly be related to the occurrence of a single mutational event in a population of susceptible individuals, although alternative models are plausible within the complexity of the process of carcinogenesis.
