Coxiella burnetii infection (Q fever) is a widespread zoonosis with low endemicity in Switzerland, therefore no mandatory public report was required. A cluster of initially ten human cases of acute Q fever infections characterized by prolonged fever, asthenia and mild hepatitis occurred in 2012 in the terraced vineyard of Lavaux. Epidemiological investigations based on patients' interviews and veterinary investigations included environmental sampling as well as Coxiella-specific serological assay and molecular examinations (real-time PCR in vaginal secretions) of suspected sheep. These investigations demonstrated that 43% of sheep carried the bacteria whereas 30% exhibited anti-Coxiella antibodies. Mitigation measures, including limiting human contacts with the flock, hygiene measures, flock vaccination and a public official alert, have permitted the detection of four additional human cases and the avoidance of a much larger outbreak. Since November 2012, mandatory reporting of Q fever to Swiss public health authorities has been reintroduced. A close follow up of human cases will be necessary to identify chronic Q fever.

BACKGROUND After cardiac surgery with cardiopulmonary bypass (CPB), acquired coagulopathy often leads to post-CPB bleeding. Though multifactorial in origin, this coagulopathy is often aggravated by deficient fibrinogen levels. OBJECTIVE To assess whether laboratory and thrombelastometric testing on CPB can predict plasma fibrinogen immediately after CPB weaning. PATIENTS / METHODS This prospective study in 110 patients undergoing major cardiovascular surgery at risk of post-CPB bleeding compares fibrinogen level (Clauss method) and function (fibrin-specific thrombelastometry) in order to study the predictability of their course early after termination of CPB. Linear regression analysis and receiver operating characteristics were used to determine correlations and predictive accuracy. RESULTS Quantitative estimation of post-CPB Clauss fibrinogen from on-CPB fibrinogen was feasible with small bias (+0.19 g/l), but with poor precision and a percentage of error >30%. A clinically useful alternative approach was developed by using on-CPB A10 to predict a Clauss fibrinogen range of interest instead of a discrete level. An on-CPB A10 ≤10 mm identified patients with a post-CPB Clauss fibrinogen of ≤1.5 g/l with a sensitivity of 0.99 and a positive predictive value of 0.60; it also identified those without a post-CPB Clauss fibrinogen <2.0 g/l with a specificity of 0.83. CONCLUSIONS When measured on CPB prior to weaning, a FIBTEM A10 ≤10 mm is an early alert for post-CPB fibrinogen levels below or within the substitution range (1.5-2.0 g/l) recommended in case of post-CPB coagulopathic bleeding. This helps to minimize the delay to data-based hemostatic management after weaning from CPB.

A 37-year-old man presented with a 4-day history of nonbloody diarrhea, fever, chills, productive cough, vomiting, and more recent sore throat. He worked for the municipality in a village in the Swiss Alps near St. Moritz. Examination showed fever (40 °C), hypotension, tachycardia, tachypnea, decreased oxygen saturation (90 % at room air), and bibasilar crackles and wheezing. Chest radiography and computed tomography scan showed an infiltrate in the left upper lung lobe. He responded to empiric therapy with imipenem for 5 days. After the imipenem was stopped, the bacteriology laboratory reported that 2/2 blood cultures showed growth of Francisella tularensis. He had recurrence of fever and diarrhea. He was treated with ciprofloxacin (500 mg twice daily, oral, for 14 days) and symptoms resolved. Further testing confirmed that the isolate was F. tularensis (subspecies holarctica) belonging to the subclade B.FTNF002-00 (Western European cluster). This case may alert physicians that tularemia may occur in high-altitude regions such as the Swiss Alps.

Plants release herbivore-induced volatiles (HIPVs), which can be used as cues by plants, herbivores and natural enemies. Theory predicts that HIPVs may initially have evolved because of their direct benefits for the emitter and were subsequently adopted as infochemicals. Here, we investigated the potential direct benefits of indole, a major HIPV constituent of many plant species and a key defence priming signal in maize. We used indole-deficient maize mutants and synthetic indole at physiologically relevant doses to document the impact of the volatile on the generalist herbivore Spodoptera littoralis. Our experiments demonstrate that indole directly decreases food consumption, plant damage and survival of S. littoralis caterpillars. Surprisingly, exposure to volatile indole increased caterpillar growth. Furthermore, we show that S. littoralis caterpillars and adults consistently avoid indole-producing plants in olfactometer experiments, feeding assays and oviposition trials. Synthesis. Together, these results provide a potential evolutionary trajectory by which the release of a HIPV as a direct defence precedes its use as a cue by herbivores and an alert signal by plants. Furthermore, our experiments show that the effects of a plant secondary metabolite on weight gain and food consumption can diverge in a counterintuitive manner, which implies that larval growth can be a poor proxy for herbivore fitness and plant resistance.

BACKGROUND National safety alert systems publish relevant information to improve patient safety in hospitals. However, the information has to be transformed into local action to have an effect on patient safety. We studied three research questions: How do Swiss healthcare quality and risk managers (qm/rm(1)) see their own role in learning from safety alerts issued by the Swiss national voluntary reporting and analysis system? What are their attitudes towards and evaluations of the alerts, and which types of improvement actions were fostered by the safety alerts? METHODS A survey was developed and applied to Swiss healthcare risk and quality managers, with a response rate of 39 % (n=116). Descriptive statistics are presented. RESULTS The qm/rm disseminate and communicate with a broad variety of professional groups about the alerts. While most respondents felt that they should know the alerts and their contents, only a part of them felt responsible for driving organizational change based on the recommendations. However, most respondents used safety alerts to back up their own patient safety goals. The alerts were evaluated positively on various dimensions such as usefulness and were considered as standards of good practice by the majority of the respondents. A range of organizational responses was applied, with disseminating information being the most common. An active role is related to using safety alerts for backing up own patient safety goals. CONCLUSIONS To support an active role of qm/rm in their hospital's learning from safety alerts, appropriate organizational structures should be developed. Furthermore, they could be given special information or training to act as an information hub on the issues discussed in the alerts.

We study how the democratization of the diffusion of research through the Internet could have helped non traditional fields of research. The specific case we approach is Heterodox Economics as its pre-prints are disseminated through NEP, the email alert service of RePEc. Comparing heterodox and mainstream papers, we find that heterodox ones are quite systematically more downloaded, and particularly so when considering downloads per subscriber. We conclude that the Internet definitely helps heterodox research, also because other researcher get exposed to it. But there is still room for more participation by heterodox researchers.

The prevalence of obesity has reached epidemic proportions in the United States. Twenty-five percent of school aged students are overweight. Schools have the opportunity to help slow this epidemic. School cafeterias in the United States feed millions of students every day through the National School Lunch Program.^ Point-of-sale machines are used in most school cafeterias to help streamline the process of purchasing school lunches. The point-of-sale software allows school personnel to place special notes on student's accounts to provide alerts about parental requests. This study investigated what the alerts are used for, who uses the alerts, and if there are any patterns by demographic characteristics. ^ Counts and percentages were used to determine what the alerts were used for and who used them. This study found that students who were white non-Hispanic, paid status, or in elementary school were most likely to have alerts placed on their accounts. Also, the majority of point-of-sale alerts were used as allowances (i.e., allowed to purchase snacks from the balance on the school lunch account), rather than restrictions (i.e., restricted from purchasing high calorie foods or specific food items). Using chi-square analysis, a total of 688 alerts were analyzed. There were significant differences in alert frequencies for intent category by grade level (p=0.000), snack access (p=0.000), and gender (p=0.002). Therefore, the results are significant, and one can conclude there is a significant relationship between gender, grade level, and snack access, and the presence of an alert on the school lunch account.^ Also, school administrators may want to take into consideration possible changes to their program, such as requiring more time to run the software. The results of this study can assist school administrators to better understand that a point-of-sale alert program may help their school lunch programs run more efficiently, while also providing parental influence on students’ food choices at the point-of-sale.^ School food service authorities should consider implementing a structured point-of-sale alert policy to encourage parental input on their children's food choices. When implementing the point-of-sale policy, schools should publicize this policy online, through school lunch menus, and parent communications increase participation throughout the school district.^

Placenta previa is alleged to be more common among women with a history of prior induced abortion. To investigate further whether there is a relationship between previous induced abortion and subsequent pregnancy complication of placenta previa, a matched case-comparison study was conducted comparing the reproductive histories of 256 women with placenta previa matched on age, date of delivery, and hospital with those of 256 women having normal deliveries and cesarean section deliveries without placental complications.^ Women with placenta previa had a twofold increase in the odds of having had one previous induced abortion (odds ratio 2.25) over women with no placental complications. Women with placenta previa and two or more previous induced abortions had a sevenfold increase in odds.^ The significant association of placenta previa and previous induced abortion remained after including gravida status, previous dilatation and curettage (D&C) status, previous spontaneous abortion, and race in a conditional logistic regression model. There is interaction between high gravidity and previous spontaneous abortion. Dilatation and curettage is associated with placenta previa primarily because women with abortion histories have also had a dilatation and curettage.^ Women who are seeking abortion and wish to have children later should be informed that there may be a longterm effect of developing placental complications in subsequent pregnancies. Women who have had at least one induced abortion or any dilatation and curettage procedure should be monitored carefully during any subsequent pregnancy for the risk of the complication of placenta previa. This knowledge should alert the physician or nurse-midwife to treat those women with a history of previous induced abortions as potential high risk pregnancies and could perhaps reduce maternal and fetal morbidity rates. ^

This study evaluated the administration-time-dependent effects of a stimulant (Dexedrine 5-mg), a sleep-inducer (Halcion 0.25-mg) and placebo (control) on human performance. The investigation was conducted on 12 diurnally active (0700-2300) male adults (23-38 yrs) using a double-blind, randomized sixway-crossover three-treatment, two-timepoint (0830 vs 2030) design. Performance tests were conducted hourly during sleepless 13-hour studies using a computer generated, controlled and scored multi-task cognitive performance assessment battery (PAB) developed at the Walter Reed Army Institute of Research. Specific tests were Simple and Choice Reaction Time, Serial Addition/Subtraction, Spatial Orientation, Logical Reasoning, Time Estimation, Response Timing and the Stanford Sleepiness Scale. The major index of performance was "Throughput", a combined measure of speed and accuracy.^ For the Placebo condition, Single and Group Cosinor Analysis documented circadian rhythms in cognitive performance for the majority of tests, both for individuals and for the group. Performance was best around 1830-2030 and most variable around 0530-0700 when sleepiness was greatest (0300).^ Morning Dexedrine dosing marginally enhanced performance an average of 3% with reference to the corresponding in time control level. Dexedrine AM also increased alertness by 10% over the AM control. Dexedrine PM failed to improve performance with reference to the corresponding PM control baseline. With regard to AM and PM Dexedrine administrations, AM performance was 6% better with subjects 25% more alert.^ Morning Halcion administration caused a 7% performance decrement and 16% increase in sleepiness and a 13% decrement and 10% increase in sleepiness when administered in the evening compared to corresponding in time control data. Performance was 9% worse and sleepiness 24% greater after evening versus morning Halcion administration.^ These results suggest that for evening Halcion dosing, the overnight sleep deprivation occurring in coincidence with the nadir in performance due to circadian rhythmicity together with the CNS depressant effects combine to produce performance degradation. For Dexedrine, morning administration resulted in only marginal performance enhancement; Dexedrine in the evening was less effective, suggesting the 5-mg dose level may be too low to counteract the partial sleep deprivation and nocturnal nadir in performance. ^

Prevalence and mortality rates for non-insulin dependent (Type II) diabetes mellitus are two to five times greater in the Mexican-American population than in the general U.S. population. Diabetes has been associated with risk factors which increases the likelihood of developing atherosclerosis. Relatives of noninsulin dependent diabetic probands are at increased risk of developing diabetes; and offspring of diabetic parents are at greater risk. Elevation in risk factor levels clearly began to develop prior to adulthood. Therefore an excess of these risk factors are expected among offspring and relatives of diabetics.^ The purposes of this study were to describe levels of risk factors within a group of Mexican American children who were identified through a diabetic proband, and to determine if there was a relationship between risk factor levels and heritability. Data from three hundred and seventy-six children and adolescents between the ages of 7 and 13 years, inclusively, were analyzed. These children were identified through a diabetic proband who participated in the Diabetes Alert Study. This study group was compared to a representative sample of Mexican American children, who participated in the Hispanic Health and Nutrition Examination Survey.^ For females, there were statistically significant associations between upper body fat distribution and increased systolic and diastolic blood pressure after adjusting for age and measures of fatness. Body mass index was positively related to and explained a significant portion of the variability in systolic blood pressure, total cholesterol, and HDL-cholesterol, for males only. No relationship was found between degree of relationship to the diabetic proband and risk factor levels. The most likely explanations for this were insufficient sample size to detect differences, and/or incomplete ascertainment of pedigree information.^ Although there was evidence that these Mexican American children are fatter and have more central fat distribution than non-Hispanic children, there is no evidence of increased risk for diabetes and/or cardiovascular disease at these ages. ^

Por el éxito y trascendencia de sus eventos anteriores, el Instituto CIFOT siente la obligación de hacer conocer las principales conclusiones del II Seminario de Ordenamiento Territorial, el que comienza a marcar pautas a partir de las preocupaciones comunes, enfoques teórico-metodológicos prevalecientes en el Ordenamiento Territorial, la planificación Estratégica y Ambiental, como también sobre las prácticas de gestión de la información territorial. Se sintetiza la idea central de las conferencias Magistrales: - Dr. Juan Gastó- Pontificia Universidad Católica de Chile- presenta “ La Ordenación Territorial como eje del Desarrollo Rural", cuyo punto central es la imposibilidad de separar la problemática territorial urbana de la rural. - Dr. Eduardo Salinas- Universidad de La Habana , Cuba- en “El Ordenamiento Territorial como instrumento de la Planificación y Gestión Ambiental" establece la necesidad de una planificación sustentable ambientalmente, con una concepción sistémica y holística de los problemas. -Dra. Elsa Laurelli -Universidad de La Plata , Argentina- en “Nuevas Tendencias del Ordenamiento Territorial en una Economía de Mercado. Limitaciones y posibilidades" plantea coexistencia de áreas receptoras de IDE vs espacios degradados y con problemáticas sociales y reflexiona sobre el rol del Estado para atenuar los efectos del mercado en el territorio y la sociedad. - Dr. Pablo Ciccolella -UBA-, Argentina. En “ Desafíos y opciones en la Gestión Urbana bajo el Capitalismo Global: Planificación Estratégica y Desarrollo Económico-Territorial" alerta sobre la planificación llave en mano que genera un desarrollo elitista, banal y efímero. - Dr. Mariano Zamorano -Universidad Nacional de Cuyo, Mendoza- presenta “ Una propuesta de Regionalización de la Provincia de Mendoza sobre la base de la Lógica Territorial " destinada a optimizar la gestión municipal y provincial. Al II Seminario de Ordenamiento Territorial concurren alrededor de 140 personas y se exponen 43 trabajos en las siguientes áreas temáticas : - 1 Nuevas tendencias en el Ordenamiento territorial . - 2 Ambiente y Ordenamiento Territorial. - 3 El Ordenamiento Territorial en el ámbito urbano. - 4 El Ordenamiento Territorial en el ámbito rural. - 5 La gestión de la información en el Ordenamiento Territorial. - 6 El rol de las Instituciones en el Ordenamiento Territorial. Conclusiones De l rico debate e intercambio de ideas realizado durante el II Seminario, se extraen tres grandes temas: - La necesidad de una visión general y holística del territorio, evitando la fragmentación disciplinar. - La interdisciplina, como campo de convergencia de problemáticas complejas. La planificación estratégica como instancia participativa y visión integral del territorio. - La metodología para el Ordenamiento Territorial debe ser verdaderamente aplicada. No se puede seguir planificando con una racionalidad limitada en busca de una imagen objetivo rígida mientras el territorio, conformado por sistemas complejos y abiertos, está en constante cambio por exigencias propias de lo global. - Un Estado en retirada no contiene la estructura necesaria ni el consenso para imponerse en sociedades democráticas con dominio absoluto de tipo capitalista.

La gestión del territorio no cuenta hasta el presente con una respuesta clara en cuanto a acciones a desarrollar para una concreta toma de decisiones. Para ello es necesario contar con información precisa y oportuna. Aquí los SIG se presentan como verdaderos sistemas de gestión en los que interactúan los componentes tecnológicos, organizacionales, metodológicos y estadísticos, que permiten elaborar planes de ordenamiento territorial y de manejo ambiental, monitorear la biodiversidad y construir indicadores ambientales. Su organización se basa en subsistemas tales como: • modelo de organización de la información espacial (que sustenta la plataforma SIG y de la Teledetección ), el que genera una base de datos relacional asociada a información contenida en el observatorio, representa cartográficamente los inicadores ambientales y el monitoreo de los mismos; • la metadata que incorpora las fuentes y datos vinculados a la documentación de datos geoespaciales digitales estandarizados y, por ultimo, • el modelo de monitoreo de la biodiversidad que conlleva a una serie de procesos tendientes especializar y analizar la dinámica presente en la cobertura vegetal a partir de imágenes del programa Landsat. El modelo involucra una integración de procesos apoyados en métodos científicos de teledetección y Sistemas de Información geográfica, permitiendo así el monitoreo para el diagnostico de estado actual de la cobertura marítima y terrestre, el análisis multitemporal, la espacialización y la transferencia de resultados. Un resultado directo de esta metodología es la detección de alertas tempranas.

Uno de los objetivos del Programa de Ordenamiento y Protección de los Recursos Naturales de la Costa Atlántica de Río Negro es promover experiencias innovadoras, vinculadas a la protección del patrimonio natural y cultural del litoral costero rionegrino. Dentro de este marco, el objetivo general es establecer las bases para un desarrollo sustentable. Esto no es posible, si no se acompaña de una fuerte sensibilización ambiental dirigida a diferentes sectores sociales respecto de los valores que representa este ecosistema costero, actividad desarrollada en el marco del Proyecto Desarrollo de una Política de Sensibilización ambiental. La implementación de una estrategia de Educación Ambiental que permita generar en la comunidad una mayor capacidad para comprender el ambiente y que contribuyan a valorar el patrimonio natural y cultural, es el eje fundamental para alcanzar el desarrollo sustentable de la región. Es por ello que se plantea el objetivo de generar una política integral de sensibilización ambiental que permita incluir la temática ambiental en los diferentes sectores sociales y modalidades del sistema educativo. Para lograrlo se realiza el Primer Seminario Taller sobre Diseño de una Política de Capacitación y Sensibilización Ambiental, que es el primer paso que permitió generar las bases de una propuesta de una Política Integral de Sensibilización Ambiental. Posteriormente se realiza una encuesta dirigida a la comunidad en general y a docentes en la que se propone analizar cada una de las problemáticas ambientales reconocidas a la luz de cuatro variables: muy grave, grave, leve y no conoce/no contesta. No fue intención realizar un análisis profundo y detallado de las variables sino resaltar grandes rasgos que permitan establecer comparaciones para su ordenamiento y tratamiento. También la se realiza un Curso para Docentes que brinda el marco propicio para la Formulación e Implementación de una Política de Sensibilización Ambiental. Otra actividad es la organización de un concurso anual "Conozcamos Nuestras Costas" dirigido a la comunidad educativa, en el que participaron activamente 430 alumnos pertenecientes a las tres localidades costeras. Se elabora y distribuye materiales de sensibilización ambiental elaborados luego de un trabajo de diagnóstico, recopilación de información y material fotográfico. El mismo se organizó en sets de 10 juegos cada uno (rompecabezas, libro de imágenes, memotest, entre otros), cuyo contenido es de flora y fauna, áreas de mayor sensibilidad ecológica y los principios de conservación. Por último se realiza un Taller para la Cooperación en la Prevención y Mitigación de Impactos Ambientales en la Costa Atlántica. Como resultado de este taller se obtuvo una Red de Alerta y Comunicación, que contribuya a la formalización y fortalecimiento de la ya existente. La creación de un Centro de un Coordinación Ambiental (CCA) que tendría su sede en la Dirección de Defensa Civil.

En este artículo se presentan avances de una investigación, en el campo de la Educación Especial, que aborda los procesos de derivación de educación común a educación especial de niños y niñas que habitan en contexto de pobreza. Dado que la investigación se funda en el interés por documentar y visibilizar las tramas altamente naturalizadas de la cotidianeidad escolar, se plantea que las derivaciones a educación especial representadas en las intervenciones del Centro de Servicios Alternativos y Complementarios alertarían ante posibles procesos complejos y contradictorios de inclusión/exclusión escolar. Por un lado, se parte de concepciones que consideran que los contextos de pobreza significan un “déficit" en relación a las posibilidades educativas de niños/as, inscribiéndolo como una “carencia", “deficiencia", no sólo social y económica, sino también “cultural" y “simbólica", y ante ello la necesidad de pensar en una oferta educativa “adecuada" y “diferenciada". Por otro lado, esta oferta educativa es identificada con la educación especial a través de las intervenciones de los Centros de Servicios Alternativos y Complementarios, configurándose así circuitos escolares diferenciados que vincularían a la pobreza con la educación especial, “patologizando" las desigualdades sociales y económicas al interior del sistema educativo.
