Resultados clĂnicos iniciales y variables pronĂłsticas en la implementaciĂłn de un CĂłdigo Sepsis en un Hospital Universitario de alta complejidad
Objective: To assess the impact of the first months of application of a Code Sepsis in a high complexity hospital, analyzing patientÂŽs epidemiological and clinical characteristics and prognostic factors.
Methods: A long-term observational study was carried out throughout a consecutive period of seven months (February 2015 - September 2015). The relationship with mortality of risk factors, and analytic values was analyzed using uni- and multivariate analyses.
Results: A total of 237 patients were included. The in-hospital mortality was 24% at 30 days and 27% at 60 days. The mortality of patients admitted to Critical Care Units was 30%. Significant differences were found between the patients who died and those who survived in mean levels of creatinine (2.30 vs 1.46 mg/dL, p 65 years (OR 5.33, p 3 mmol/L (OR 5,85, p 1,2 mgr /dL (OR 4,54, p <0,05) and shock (OR 6,57, P <0,05).
Conclusions: The epidemiological, clinical and mortality characteristics of the patients in our series are similar to the best published in the literature. The study has identified several markers that could be useful at a local level to estimate risk of death in septic patients. Studies like this one are necessary to make improvements in the Code Sepsis programsObjetivo. Evaluar el impacto de un programa educativo y
organizativo llamado CĂłdigo Sepsis, en los primeros siete meses
de su aplicaciĂłn en un hospital de alta complejidad.
Material y métodos. Se realizó un estudio observacional
durante un perĂodo consecutivo de siete meses (Febrero
2015-Septiembre 2015). Se analizĂł la relaciĂłn con la mortalidad
de los factores de riesgo y los valores analĂticos usando
anĂĄlisis uni y multivariante.
Resultados. Se incluyeron un total de 237 pacientes. La
mortalidad intrahospitalaria a los 30 dĂas fue del 24 % y del
27% a los 60 dĂas. La mortalidad de los pacientes ingresados
en Unidades de Cuidados CrĂticos fue del 30%. Se encontraron
diferencias significativas entre los pacientes que murieron y
los que sobrevivieron en sus valores medios de creatinina (2,30
vs 1,46 mg/dL, p <0,05), ĂĄcido lĂĄctico (6,10 vs 2,62 mmol/L, p
<0,05) y procalcitonina (23,27 vs 12,73 mg/dL, p <0,05). Se encontrĂł
una tendencia lineal estadĂsticamente significativa entre
los valores de la escala SOFA y la mortalidad (p <0,05). En el
anĂĄlisis multivariante se identificaron otros factores de riesgo
independientes asociados con la muerte: edad > 65 años (OR
5,33, p 3 mmol/L (OR 5,85, p <0,05),
creatinina > 1,2 mgr/dL (OR 4,54, p <0,05) y el shock (OR 6,57,
P <0,05).
Conclusiones. La mortalidad en este estudio se encuentra
dentro de los lĂmites de los ensayos clĂnicos mĂĄs recientes de
sepsis. El estudio ha identificado varios marcadores que podrĂan
ser Ăștiles a nivel local para estimar el riesgo en pacientes
sépticos. Estudios como éste son necesarios para hacer mejoras
en los programas de CĂłdigo Sepsi
Reforestation model with native plants of the Jaraba swamp through the IEP
La sequĂa en Ă©poca de verano ocasionada por la acciĂłn
directa del sol sobre las costas a causa de la perdida
de vegetaciĂłn en las mismas, es una realidad que afecta
a las poblaciones ribereñas en la actualidad. Los
programas de reforestaciĂłn son herramientas Ăștiles
en la mejora de la calidad de vida de las diferentes
partes del mundo afectadas por esta realidad. Este
estudio tuvo como propósito diseñar un modelo de
reforestación con plantas nativas de la ciénaga de
Jaraba mediante la InvestigaciĂłn como Estrategia
PedagĂłgica (IEP). La metodologĂa se orientĂł bajo el
enfoque cualitativo, utilizando el tipo de investigaciĂłn
acción, desde un diseño descriptivo, exploratorio. Para
la recolección de datos se utilizaron técnicas como;
anĂĄlisis documental a partir de la implementaciĂłn
de un software que analiza las caracterĂsticas de los
arbustos y semillas propicias para la reforestaciĂłn.
La poblaciĂłn estuvo conformada por cincuenta (50)
estudiantes de la IED Antonio Bruges Carmona sede
ERM de Jaraba del Municipio de Santa Ana Magdalena.
Dando como resultados la creaciĂłn de un
vivero natural con diferentes especies de plantas
seleccionadas para este modelo ecolĂłgico. Llegando
a la conclusiĂłn que existe la necesidad de fortalecer
la cultura ambiental por parte de los habitantes y
visitantes en las orillas de la ciénaga, donde se vierte
toda clase de desechos que difĂcilmente alcanzarĂĄn
un nivel de degradaciĂłn.The drought in summer time caused by the direct
action of the sun on the coasts because of the loss
of vegetation in them, is a reality that affects the
riverside populations at present. Reforestation programs
are useful tools in improving the quality of
life in different parts of the world affected by this
reality. The purpose of this study was to design a
reforestation model with native plants of the Jaraba
swamp through Research as a Pedagogic Strategy
(IEP). The methodology was oriented under the
qualitative approach, using the type of action research,
from a descriptive, exploratory design. For
the collection of data, techniques such as; documentary
analysis based on the implementation of software
that analyzes the characteristics of shrubs
and seeds that are conducive to reforestation. The
population was conformed by fifty (50) students
of the IED Antonio Bruges Carmona ERM headquarters
of Jaraba of the Municipality of Santa
Ana Magdalena, giving as results the creation of
a natural nursery with different species of plants
selected for this ecological model. Reaching the
conclusion that there is a need to strengthen the
environmental culture on the part of the inhabitants
and visitors on the banks of the swamp, where
all kinds of waste that will hardly reach a level of
degradation are poured
Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2
The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and lowâmiddle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of âsingle-useâ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for lowâmiddle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both highâ and lowâmiddleâincome countries
A comparative study of the ZnO growth on graphene and graphene oxide: the role of the initial oxidation state of carbon
The role of the oxidation state of carbon on the early stages of growth of metal oxides was studied for the particular case of ZnO deposition on graphene and graphene oxide on SiO2 (G/SiO2 and GO/SiO2, respectively) substrates. The growth was carried out by thermal evaporation of metallic Zn under an oxygen atmosphere at room temperature. This technique permits quasi-equilibrium conditions during the oxide growth, allowing the characterization of the fundamental interaction between ZnO and the graphene-based substrates. Although in both cases ZnO follows a VolmerâWeber growth mode controlled by nucleation at defects, the details are different. In the case of the GO/SiO2 substrate, the nucleation process acts as a bottleneck, limiting the coverage of the complete surface and allowing the growth of very large ZnO structures in comparison to G/SiO2. Moreover, by studying the Zn-LMM Auger spectra, it is shown how the initial nature of the substrate influences the composition of the ZnO deposit during the very early stages of growth in terms of Zn/O atomic ratio. These results are compared to those previously reported regarding ZnO growth on graphite and graphene on Cu (G/Cu). This comparison allows us to understand the role of different characteristics of graphene-based substrates in terms of number of defects, oxidation state, graphene support substrate and number of graphene layers.This investigation has been funded by the MINECO of Spain through the FIS2015-67367-C2-1-P project and by the Comunidad de Madrid through the NANOMAGCOST-CM P2018/NMT4321 project.
