Shared commitments towards social resilience in populations vulnerable to extreme weather conditions

The processes involved in moving from vulnerability to resilience imply shared commitments between community and social actors. This paper documents such a shared experience among groups of high school learners from three cities in Veracruz state, Mexico, which have been periodically affected by extreme weather conditions. Earlier research carried out with high school learners and teachers analysed the resilience that the community demonstrated while coping with, and recovering from, an environmental contingency. In this initial research stage, we obtained information from official sources, and from questionnaires and interviews on the physical and social elements that impact the learners’ vulnerability. In addition, we identified the participants’ interest in being involved in processes to build resilient communities. With all this information, it was then possible to make progress in the development of strategies towards building the relevant capacities in those high school learners interested in becoming change agents in their own communities. The research also contributed to the creation of intra-community contingency support networks in the three municipalities participating in the study. In addition, high school learners and teachers became interested in initiating environmental protection activities and in taking on the commitment to communicate their concerns to decision-makers in their own communities to try and influence public policy. Accordingly, these actions and shared commitments can be seen to foster community and social resilience

Systemic lupus erythematosus is a chronic autoimmune disease of multiorgan commitment, uncommon in the male sex, where it occurs with greater morbidity. The clinical case of a man who debuts with severe systemic commitment, adding refractory bullous skin commitment to immunosuppressive treatment, with a good response after Rituximab.El lupus eritematoso sistémico, es una enfermedad crónica autoinmune de compromiso multiorgánico, infrecuente en el sexo masculino, donde se presenta con una mayor morbimortalidad. Se presenta el caso clínico de un hombre que debuta con compromiso sistémico grave, agregando compromiso cutáneo bulloso refractario a tratamiento inmunosupresor, con una buena respuesta posterior a Rituximab.

Representaciones sociales sobre cambio climático en dos grupos de estudiantes de educación secundaria de España y bachillerato de México

El objetivo de la investigación que se presenta fue analizar y contrastar las representaciones sociales (RS) sobre cambio climático (CC) de estudiantes de secundaria y bachillerato de España y México. La metodología fue de corte cualitativo, utilizando esquemas gráfi cos y entrevistas semiestructuradas, con un enfoque procesual. Los hallazgos revelan la construcción de diversos tipos de RS, predominando, en ambos grupos, la que privilegia información sobre aspectos biofísicos del CC. Esta cualidad común deriva de procesos globalizados de difusión del fenómeno. También, en porcentajes similares, ambos grupos expresan una visión lejana acerca de sus afectaciones. En la mayoría de los casos reconocen la infl uencia antrópica en el CC y las consecuencias en el medio natural. Asimismo, se advierte el infl ujo del discurso mediático sobre el fenómenoTh e objective of the current study was to analyze and contrast the social representations of climate change among secondary students in Spain and high school students in Mexico. Th e methodology was qualitative and used graphic systems and semi-structured interviews, with a procedural approach. Th e fi ndings reveal the construction of diverse types of social representations, and predominant in both groups are representations that favor information on the biophysical aspects of climate change: a result of globalized processes involving the spread of information about the phenomenon. Both groups also express, in similar percentages, a distant view of the aff ects of climate change. Most cases recognize the anthropic infl uence on climate change and the consequences for the environment. In addition, media involvement in the phenomenon is recognizedS

El cambio climático en el bachillerato : aportes pedagógicos para su abordaje

Ministerio de Economía y Competitividad del Gobierno de España, en el marco del VI Programa Nacional 2016-18La investigación presentada tiene como propósito conocer elementos de las representaciones sociales (RS) sobre cambio climático (CC) en estudiantes de bachillerato general y tecnológico del estado de Veracruz, y formular aportaciones pedagógicas orientadas a promover acciones ecociudadanas en estudiantes de este nivel. Se ha realizado una investigación cuantitativa con una muestra de 858 estudiantes, a través de un cuestionario demoscópico conformado por 43 preguntas cerradas. La hipótesis de investigación es: si no existe diferencia significativa entre las RS sobre CC en los dos grupos de estudio, cabe pensar que es la cultura común la que configura en mayor medida dicha RS. Los resultados muestran que este colectivo construye una RS del CC limitada a su dimensión biofísica con presencia de conceptos difusos, sin identificarse diferencias significativas entre las RS de los grupos.This research aims to know the elements of the social representations (SR) on climate change (CC) in students of general (BG) and technological (BT) high school of the state of Veracruz, and make pedagogical contributions oriented to promote eco-citizen actions in students of this level. A quantitative investigation was carried out with a sample of 858 students, through a demographic questionnaire of 43 closed questions. The research hypothesis is: if there is no significant difference between the SRs on CC in the two study groups, it is possible to think that it is the common culture that configures this SR to a greater extent. The results show that this group builds a SR of the CC limited to its biophysical dimension with the presence of diffuse concepts, without identifying significant differences between the SRs of the groups

(188)Re radiopharmaceuticals for radiosynovectomy: evaluation and comparison of tin colloid, hydroxyapatite and tin-ferric hydroxide macroaggregates

BACKGROUND: Radiosynovectomy is a therapy used to relieve pain and inflammation from rheumatoid arthritis and related diseases. In this study three (188)Re particulate compounds were characterized according to their physico-chemical properties and their biological behavior in rabbits. The results were compared in order to establish which was the radiopharmaceutical that better fits the requirements of this kind of radiotherapy. METHODS: Three radiopharmaceutical formulations, tin colloid, hydroxyapatite particles (HA) and ferric hydroxide macroaggregates coated with tin colloid (FHMA), were physically characterized (number, volume and surface of the particles). For this purpose laser diffraction methodology was used. To evaluate cavity leakage of activity the following studies in New Zealand rabbits were performed: scintigraphic images for 48 hr after intraarticular injection of each radiopharmaceutical, biodistribution at 48 hr and urine samples collection during the first 24 hr post-radiopharmaceutical administration. RESULTS: Labeling procedures for (188)Re-HA and (188)Re-Sn-FHMA were labour intensive while (188)Re-Sn was easily prepared. Furthermore, (188)Re-Sn colloid offered the greatest surface area in the 2–10 microm range and was obtained with a radiochemical purity over 95%, while percentage of bound activity for (188)Re-HA and (188)Re-Sn-FHMA were 55% and 92% respectively. Stability was verified for the three radiopharmaceuticals for 24 hr. Scintigraphic studies and biodistribution in rabbits after intraarticular administration of the radiopharmaceuticals showed relevant activity only in the knee, this being over 90% of the residual activity in the whole body at 48 hr in every case. Renal elimination of (188)Re-Sn colloid and (188)Re-Sn-FHMA was detected by activity measurements in urine samples, during the first 12 hr post-radiopharmaceutical injection. The percentage of activity retained in the knee was 69.1% for (188)Re-Sn colloid, 55.1% for (188)Re-Sn-FHMA and 33.6% for (188)Re-HA. CONCLUSION: The (188)Re-Sn colloid was easy to prepare, minimum facilities were required, was stable for 24 hr and showed minimal leakage from the joint after intraarticular injection into the rabbit's knee. Furthermore, (188)Re-Sn colloid has greater retention in the knee when it is compared with the other radiopharmaceuticals, so it could provide the best therapeutic effect/absorbed dose ratio for the patient

Re-HEDP : pharmacokinetic characterization, clinical and dosimetric evaluation in osseous metastatic patients with two levels of radiopharmaceutical dose

BACKGROUND: A study for pain relief therapy with (188)Re-HEDP was done in patients with bone metastases secondary to breast and prostate cancer. MATERIALS AND METHODS: Patients received 1.3 or 2.2 GBq, in single or multiple doses. Platelets, white and red cells were evaluated during 11 weeks. Pharmacokinetic characterization was done from blood and urine samples for 5 patients along 24 hours. Urinary excretion was evaluated in other 16 patients during 6 hours. Bone uptake was estimated as remaining activity in whole body. Scintigraphic images were acquired at 2 and 24 hs post-administration. Absorbed dose in bone marrow was estimated with Mirdose3. Analgesics intake and pain score were daily recorded. Tumour markers (PSA, and Tn-structure) were monitored in 9 patients during 4 to 6 months. Single doses of low activity (1.3 GBq) were given to twelve patients. Nine patients received multiple doses. RESULTS: All except one patient had normal levels of platelets, white and red cells. Remaining dose in blood at 2 hours was 9%. Urinary elimination was 58%. Bone uptake at 24 hours was 43% (mean value; n = 5). No changes of the haematological parameters were detected along follow-up period. Pain relief was evidenced by decrease or supression of opioid analgesic and by subjective index. PSA showed a decrease in prostate cancer patients (n = 4). Tn-structure showed a significant increase after 4 to 8 months. CONCLUSION: Single or multiple dose scheme could be safely used, with administered activity of (188)Re-HEDP up to 60 mCi, with low bone marrow absorbed doses

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Revista iberoamericana de educación

Resumen tomado de la publicaciónMonográfico con el título: “Educación para el desarrollo sostenible”Durante la primera mitad de los años noventa del siglo pasado, y más específicamente a partir de la celebración de la Cumbre de la Tierra (Río de Janeiro, 1992), se inició un proceso tendiente a sustituir la noción de educación ambiental por la de educación para el desarrollo sustentable y otras nociones equivalentes. Aunque dicho proceso perdura hasta hoy en día, ya desde entonces se levantaron voces que discreparon de tales propósitos, emprendidos por diversos organismos internacionales encabezados por la UNESCO. Ello, como es obvio, ha generado diversas confusiones y tomas de postura entre los educadores ambientales. El presente trabajo se enfoca a dar cuenta de los resultados de dos encuestas aplicadas en la región de América Latina y el Caribe sobre esta situación, y al final se hacen algunas reflexiones sobre el imaginario y sobre el ideario de los educadores ambientales en el momento histórico que vivimos ahora de complejas y vertiginosos transiciones.MadridUniversidad de Burgos.
