Populismo y polarización política en la Región Andina. Entre los líderes y la demanda populista

Este artículo combina el estudio del populismo y la polarización política en Bolivia, Colombia, Ecuador y Perú. Utilizando datos agregados de la región andina, se indica una relación significativa entre la presencia de líderes populistas y el incremento en la polarización política. Luego, empleando datos individuales provenientes de una encuesta en línea a ecuatorianos mayores de 16 años, aplicada en 2019, 2020 y 2021, se consideran las actitudes políticas para el estudio de la interacción entre el populismo y la polarización política. Intuitivamente, los resultados corroboran que las actitudes políticas del electorado contribuyen al éxito electoral de líderes populistas. A su vez, las actitudes políticas aumentan indirectamente las probabilidades de polarización política

Studying the non-thermal lobes of IRAS 16547-4247 through a multi-wavelength approach

In recent years, massive protostars have turned out to be a possible population of high-energy emitters. Among the best candidates is IRAS 16547-4247, a protostar that presents a powerful outflow with clear signatures of interaction with its environment. This source has been revealed to be a potential high-energy source because it displays non-thermal radio emission of synchrotron origin, which is evidence of relativistic particles. To improve our understanding of IRAS 16547-4247 as a high-energy source, we analyzed XMM-Newton archival data and found that IRAS 16547-4247 is a hard X-ray source. We discuss these results in the context of a refined one-zone model and previous radio observations. From our study we find that it may be difficult to explain the X-ray emission as non-thermal radiation coming from the interaction region, but it might be produced by thermal Bremsstrahlung (plus photo-electric absorption) by a fast shock at the jet end. In the high-energy range, the source might be detectable by the present generation of Cherenkov telescopes, and may eventually be detected by Fermi in the GeV range

A critical view on the current use of daptomycin in Spain: The daptomise study

Background: The Study on the Clinical Use of DAPTOMycin in Spain (DAPTOMISE Study) is a national surveillance program of daptomycin use. The objectives of this study are to evaluate the current variability in daptomycin consumption across the different hospitals and the adequacy of therapy, specially focused on underdosing. Methods: All adult and pediatric patients who received, at least, one dose of daptomycin in a single week in 98 institutions in Spain were included. The adequacy of daptomycin use was evaluated with respect to the indication, dosage, adjustments after microbiology results, switching to an oral agent and length of treatment. Results: A total of 615 patients received daptomycin during the study week. The prevalence use was 2.3 patients / 100,000 inhabitants per week, 12.4 patients / 1000 admissions and 9.2 Days of Therapy (DOT) / 1000 hospital stays. These rates varied between hospitals: from 0 to 13.9 patients / 100,000 inhabitants, from 0 to 76.1 patients / 1000 admissions and from 0 to 49.4 DOT / 1000 hospital stays. The most frequent infections were bacteremia (31.6 %) and skin and soft tissue infections (17.9 %). Microbiological results were available in only 65.4 % of infections. The most frequent microorganisms were Staphylococcus aureus (192 isolates, of which 87 were resistant to methicillin) and coagulase-negative staphylococci (124 isolates). A total of 136 prescriptions (22.1 %) were underdosed. Dosages < 8 mg/kg were used for 35.6 % of endovascular infections and for 26.2 % of osteoarticular infections. Overall, 57.2 % of prescriptions were not optimal in, at least, one item. Clinical cure rate was 76.1% and mortality attributable to the infection 8.1%. Conclusion: This is the first registry that identifies the prevalence of use of daptomycin in Spain and shows a high variability in the consumption between the different hospitals. Daptomycin underdosing was present in more than 20 % of cases. (c) 2023 Published by Elsevier Ltd on behalf of King Saud Bin Abdulaziz University for Health Sciences.

Molecular, microbiological and clinical characterization of Clostridium difficile isolates from tertiary care hospitals in Colombia

In Colombia, the epidemiology and circulating genotypes of Clostridium difficile have not yet been described. Therefore, we molecularly characterized clinical isolates of C.difficile from patients with suspicion of C.difficile infection (CDI) in three tertiary care hospitals. C.difficile was isolated from stool samples by culture, the presence of A/B toxins were detected by enzyme immunoassay, cytotoxicity was tested by cell culture and the antimicrobial susceptibility determined. After DNA extraction, tcdA, tcdB and binary toxin (CDTa/CDTb) genes were detected by PCR, and PCR-ribotyping performed. From a total of 913 stool samples collected during 2013–2014, 775 were included in the study. The frequency of A/B toxins-positive samples was 9.7% (75/775). A total of 143 isolates of C.difficile were recovered from culture, 110 (76.9%) produced cytotoxic effect in cell culture, 100 (69.9%) were tcdA+/tcdB+, 11 (7.7%) tcdA-/tcdB+, 32 (22.4%) tcdA-/tcdB- and 25 (17.5%) CDTa+/CDTb+. From 37 ribotypes identified, ribotypes 591 (20%), 106 (9%) and 002 (7.9%) were the most prevalent; only one isolate corresponded to ribotype 027, four to ribotype 078 and four were new ribotypes (794,795, 804,805). All isolates were susceptible to vancomycin and metronidazole, while 85% and 7.7% were resistant to clindamycin and moxifloxacin, respectively. By multivariate analysis, significant risk factors associated to CDI were, staying in orthopedic service, exposure to third-generation cephalosporins and staying in an ICU before CDI symptoms; moreover, steroids showed to be a protector factor. These results revealed new C. difficile ribotypes and a high diversity profile circulating in Colombia different from those reported in America and European countries

Métodos de evaluación de Pastizales en Patagonia Sur

Prólogo de la presente edición: “En los últimos cincuenta años hemos observado cómo ha ido reduciéndose el stock ganadero de las provincias patagónicas. Se han ensayado muchas estrategias de fortalecimiento de la ganadería que no han dado los resultados esperados. La mayor parte de ellas estuvieron orientadas a reposición animal. Si bien científicos como el Ing. Alberto Soriano lo expresaron en 1950 nos faltó convicción para reconocer que la ganadería patagónica se basa en los forrajes que consumen sus animales. Y es allí donde debemos poner nuestras prioridades. Sin una buena alimentación no es posible tener buena reproducción, sanidad, calidad de lana y carne y avanzar en programas de genética. Por otro lado se aprecia un deterioro de los recursos naturales como consecuencia de las actividades humanas sin presupuestos de uso. El presenta Manual realiza una contribución significativa en este sentido aportando las distintas técnicas disponibles en la región para evaluar y utilizar los recursos forrajeros.” Ing. Agr.

Cruise Summary Report - MEDWAVES survey. MEDiterranean out flow WAter and Vulnerable EcosystemS (MEDWAVES)

The MEDWAVES (MEDiterranean out flow WAter and Vulnerable EcosystemS) cruise targeted areas under the potential influence of the MOW within the Mediterranean and Atlantic realms. These include seamounts where Cold-water corals (CWCs) have been reported but that are still poorly known, and which may act as essential “stepping stones” connecting fauna of seamounts in the Mediterranean with those of the continental shelf of Portugal, the Azores and the Mid-Atlantic Ridge. During MEDWAVES sampling has been conducted in two of the case studies of ATLAS: Case study 7 (Gulf of Cádiz-Strait of Gibraltar-Alboran Sea) and Case study 8 (Azores). The initially targeted areas in the Atlantic were: the Gazul Mud volcano, in the Gulf of Cádiz (GoC) area, included in the case study 7, and the Atlantic seamounts Ormonde (Portuguese shelf) and Formigas (by Azores), both part of the case study 8. In the Mediterranean the targeted areas were The Guadiaro submarine canyon and the Seco de los Olivos (also known as Chella Bank) seamount. Unfortunately it was not possible to sample in Guadiaro due to time constraints originated by adverse meteorological conditions which obligate us to reduce the time at sea focusing only in 4 of the 5 initially planned areas. MEDWAVES was structured in two legs; the first leg took place from the 21st September (departure from Cádiz harbour in Spain) to the 13th October 2016 (arrival in Ponta Delgada, São Miguel, Azores, Portugal took place the 8th of October due to the meteorological conditions that obligated to conclude the first leg earlier as planned). during the Leg 1 sampling was carried out in Gazul, Ormonde and Formigas. The second leg started the 14th October (departure from Ponta Delgada) and finished the 26th October (arrival in Málaga harbour, Spain). MEDWAVES had a total of 30 effective sampling days, being 6 days not operative due to the adverse meteorological conditions experienced during the first leg which forced us to stay in Ponta Delgada from the 08th to the 13th October. During MEDWAVES the daily routine followed a similar scheme, depending of course on the weather and sea conditions. The main activity during the day, starting early in the morning (around 08:00 AM, once the night activities were finished), was the ROV deployment. Generally a single ROV dive of around 8 hours was performed, however in several occasions two dives were carried out in the same day (see General station list, Appendix II). After the ROV (and sometimes between two dives) the Box Corer and/or Van Veen Grab and/or Multicore was deployed. After these activities, during the night CTD-Rosette deployments and MB was conducted. Accordingly to this schema the scientific personnel worked in the day or in the night watch. A total of 215 sampling stations have been covered in MEDWAVES, using the following sampling gears: Multibeam echosounder, CTD-Rosette, LADCP, Box Corer, Van Veen Grab, Multicorer and a Remotely Operated Vehicle (ROV). Table 1 sumamrised the number of sampling stations conducted with each gear in each sampling zone. Additionally MB surveys have been conducted during the transits between area

Healthcare workers hospitalized due to COVID-19 have no higher risk of death than general population. Data from the Spanish SEMI-COVID-19 Registry

Aim To determine whether healthcare workers (HCW) hospitalized in Spain due to COVID-19 have a worse prognosis than non-healthcare workers (NHCW). Methods Observational cohort study based on the SEMI-COVID-19 Registry, a nationwide registry that collects sociodemographic, clinical, laboratory, and treatment data on patients hospitalised with COVID-19 in Spain. Patients aged 20-65 years were selected. A multivariate logistic regression model was performed to identify factors associated with mortality. Results As of 22 May 2020, 4393 patients were included, of whom 419 (9.5%) were HCW. Median (interquartile range) age of HCW was 52 (15) years and 62.4% were women. Prevalence of comorbidities and severe radiological findings upon admission were less frequent in HCW. There were no difference in need of respiratory support and admission to intensive care unit, but occurrence of sepsis and in-hospital mortality was lower in HCW (1.7% vs. 3.9%; p = 0.024 and 0.7% vs. 4.8%; p<0.001 respectively). Age, male sex and comorbidity, were independently associated with higher in-hospital mortality and healthcare working with lower mortality (OR 0.211, 95%CI 0.067-0.667, p = 0.008). 30-days survival was higher in HCW (0.968 vs. 0.851 p<0.001). Conclusions Hospitalized COVID-19 HCW had fewer comorbidities and a better prognosis than NHCW. Our results suggest that professional exposure to COVID-19 in HCW does not carry more clinical severity nor mortality
