Evaluación del nivel de la vulnerabilidad sísmica en viviendas autoconstruidas en el anexo 22, San Antonio de Huarochirí, Lima, 2022

La presente investigación de Evaluación del Nivel de Vulnerabilidad Sísmica en Viviendas Autoconstruidas en San Antonio de Jicamarca - Anexo 22, Distrito de San Antonio – Huarochirí – Lima, según el RNE, tiene por objetivos establecer el nivel de vulnerabilidad frente a condiciones de sismo de las viviendas autoconstruidas de manera informal en el sistema constructivo de albañilería confinada, mediante el uso de la metodología FEMA P-154, en análisis del comportamiento de la estructura en el software ETABS y la comparación de los resultados con las normas técnicas del RNE. La metodología empleada para la presente investigación es del tipo aplicada, con un diseño de investigación no experimental. Los resultados obtenidos fueron que un 50% de las viviendas presentan un nivel de vulnerabilidad sísmica alta, 25% media y 25% baja; también, que todas las viviendas presentan irregularidades e incumplimientos relacionados a condiciones de construcción, estructuración y calidad de materiales, esto debido a la ejecución de autoconstrucciones informales con resultados de 71.88% (cumplimiento), 2.78% (cumplimiento parcial) y 25.35% (no cumplimiento); así mismo que se comprueba que al reducir los índices de autoconstrucción informal, se reduce también la severidad e intensidad de daños que pueden presentarse ante la ocurrencia de eventos sísmicos moderados y severo

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Clinical characterization of data-driven diabetes subgroups in Mexicans using a reproducible machine learning approach

Introduction Previous reports in European populations demonstrated the existence of five data-driven adult-onset diabetes subgroups. Here, we use self-normalizing neural networks (SNNN) to improve reproducibility of these data-driven diabetes subgroups in Mexican cohorts to extend its application to more diverse settings.Research design and methods We trained SNNN and compared it with k-means clustering to classify diabetes subgroups in a multiethnic and representative population-based National Health and Nutrition Examination Survey (NHANES) datasets with all available measures (training sample: NHANES-III, n=1132; validation sample: NHANES 1999–2006, n=626). SNNN models were then applied to four Mexican cohorts (SIGMA-UIEM, n=1521; Metabolic Syndrome cohort, n=6144; ENSANUT 2016, n=614 and CAIPaDi, n=1608) to characterize diabetes subgroups in Mexicans according to treatment response, risk for chronic complications and risk factors for the incidence of each subgroup.Results SNNN yielded four reproducible clinical profiles (obesity related, insulin deficient, insulin resistant, age related) in NHANES and Mexican cohorts even without C-peptide measurements. We observed in a population-based survey a high prevalence of the insulin-deficient form (41.25%, 95% CI 41.02% to 41.48%), followed by obesity-related (33.60%, 95% CI 33.40% to 33.79%), age-related (14.72%, 95% CI 14.63% to 14.82%) and severe insulin-resistant groups. A significant association was found between the SLC16A11 diabetes risk variant and the obesity-related subgroup (OR 1.42, 95% CI 1.10 to 1.83, p=0.008). Among incident cases, we observed a greater incidence of mild obesity-related diabetes (n=149, 45.0%). In a diabetes outpatient clinic cohort, we observed increased 1-year risk (HR 1.59, 95% CI 1.01 to 2.51) and 2-year risk (HR 1.94, 95% CI 1.13 to 3.31) for incident retinopathy in the insulin-deficient group and decreased 2-year diabetic retinopathy risk for the obesity-related subgroup (HR 0.49, 95% CI 0.27 to 0.89).Conclusions Diabetes subgroup phenotypes are reproducible using SNNN; our algorithm is available as web-based tool. Application of these models allowed for better characterization of diabetes subgroups and risk factors in Mexicans that could have clinical applications

Promoción turística sostenible de la reserva de la biosfera Tajo-Tejo Internacional

Convocatoria proyectos de innovación de Extremadura 2020/2021Se describe un proyecto llevado acabo por varios centros educativos ubicados en la zona de la Reserva de la Biosfera Tajo-Tejo Internacional (RBTTI) que pretendía contribuir a la transformación sostenible del entorno mediante su conocimiento y promoción, implementando las competencias digital, social y ciudadana y la cultura emprendedora mediante metodologías activas como el aprendizaje servicio. Entre los objetivos principales del proyecto destacan: dar a conocer las implicaciones de la RBTTI; diseñar una campaña de promoción de la RBTTI mediante trípticos y vídeos promocionales; conocer la Reserva a través de las principales vías pecuarias y caminos que comunican los pueblos; descubrir los principales elementos socioculturales, históricos y tradicionales de la Reserva; valorar la importancia del territorio para conservar la biodiversidad: paisajes, ecosistemas, fauna y flora representativa; relacionar la trashumancia y las vías pecuarias como rasgos identificativos de la Reserva, vinculándolo con la historia y rasgos culturales de los pueblos y valorar el emprendimiento y la iniciativa personal, el asosiacionismo y creación de redes de cooperación en y entre pueblos como motor de desarrolloExtremaduraES

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
