Diseño e implementación de una red de monitoreo de aguas subterráneas en el distrito de Santa Marta departamento del Magdalena

El presente proyecto tiene como finalidad, realizar una red de monitoreo de calidad del agua en el Distrito de Santa Marta; buscando establecer el estado y la calidad de las aguas subterráneas, con el fin de llevar el soporte para definir los lineamientos y estrategias de políticas para la protección y conservación del recurso hídrico subterráneo. Los resultados del monitoreo de las aguas subterráneas nos servirán para contribuir a mejorar su planeamiento, desarrollo, protección y manejo; anticipándonos en posibles escenarios por contaminación y deterioro de las mismas. Generalmente el monitoreo tiene por finalidad establecer las características y el comportamiento hidrogeológico, así como sus posibles variaciones, tanto espaciales como temporales, las propiedades que se monitorean comúnmente son la calidad, la reserva y la productividad. En ciudades al interior del país, así como Ciudades de países extranjeros como México, Argentina, y Brasil, han brindado el valor correspondiente a las aguas subterráneas contenidas o depositadas en los acuíferos como fuente de abastecimiento en localidades pequeñas en donde se determinan las zonas principales o eficientes para elaborar pozos profundos en donde la columna de agua brindada es suficiente y la calidad de esta es relacionada con la necesidad requerida.The present project has like purpose, to realize a network of monitoring of water quality in the District of Santa Marta; thinking about how to establish the state and the quality of the groundwater, in order to take the support to define the lineaments and politics strategies for the protection and conservation of the underground water resource. The results of the monitoring of the groundwater will serve to us to help to improve its planning, development, protection and handling; anticipating us in possible stages for contamination and deterioration of the same ones. Generally the monitoring takes as a purpose to establish the characteristics and the behavior hidrogeológico, as well as its possible changes, both spatial and temporary, the properties that monitorean commonly are the quality, the reservation and the productivity. In cities to the interior of the country, as well as Cities of foreign countries as Mexico, Argentina, and Brazil, they have offered the value corresponding to the groundwater suppressed or deposited in the aquifers as source of supplying in small localities where the main or efficient areas decide to prepare deep wells where the column of offered water is sufficient and the quality of this one is related to the required need

The impact of surgical delay on resectability of colorectal cancer: An international prospective cohort study

AIM: The SARS-CoV-2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non-delayed surgery. METHODS: This was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January-April 2020). Surgical delay was defined as an operation taking place more than 4 weeks after treatment decision, in a patient who did not receive neoadjuvant therapy. A subgroup analysis explored the effects of delay in elective patients only. The impact of longer delays was explored in a sensitivity analysis. The primary outcome was complete resection, defined as curative resection with an R0 margin. RESULTS: Overall, 5453 patients from 304 hospitals in 47 countries were included, of whom 6.6% (358/5453) did not receive their planned operation. Of the 4304 operated patients without neoadjuvant therapy, 40.5% (1744/4304) were delayed beyond 4 weeks. Delayed patients were more likely to be older, men, more comorbid, have higher body mass index and have rectal cancer and early stage disease. Delayed patients had higher unadjusted rates of complete resection (93.7% vs. 91.9%, P = 0.032) and lower rates of emergency surgery (4.5% vs. 22.5%, P < 0.001). After adjustment, delay was not associated with a lower rate of complete resection (OR 1.18, 95% CI 0.90-1.55, P = 0.224), which was consistent in elective patients only (OR 0.94, 95% CI 0.69-1.27, P = 0.672). Longer delays were not associated with poorer outcomes. CONCLUSION: One in 15 colorectal cancer patients did not receive their planned operation during the first wave of COVID-19. Surgical delay did not appear to compromise resectability, raising the hypothesis that any reduction in long-term survival attributable to delays is likely to be due to micro-metastatic disease

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Curso de agregação pedagógica, módulo de tecnologias. (Original)

Information and Communication Technologies (ICTs) play a revolutionary role in society and at school; they bring changes in the ways of relating, acting, thinking, dialoguing, exchanging information and experiences and producing knowledge. The Higher Polytechnic Institute of Porto Amboim (ISUP), from the Cuanza Sul Province, Angola, in its program for the continuous training of teachers; planned a training course in ICTs for the teachers of this institution; in order to encourage the evolution of critical thinking and the capacity for innovation and collaboration of teachers, for the development of their teaching activities through the use of ICTs. The hygienic sanitary measures adopted by the Republic of Angola to face the spread of COVID-19 reinforced the need to carry out the training course in order to be able to continue with the social object of ISUP through distance education. A diagnostic was applied to 52 teachers, which showed a low rate of use of ICT by them in their pedagogical practice, among which 23% of the use of digital platforms stand out; of this result, only 4% have mastered Moodle. The course was given over a period of 15 days, and according to the assessment of the tasks, the course participants were trained in the use of ICTs. The response of the survey applied at the end of the course showed that the objectives of the course were achieved.As Tecnologias da Informação e a Comunicação (TICs) jogam um papel revolucionário na sociedade e na escola; trazem consigo mudanças nas formas de relacionar-se, actuar, pensar, dialogar, trocar informações e experiências e produzir conhecimento.

Where Brain, Body and World Collide

The production cross section of electrons from semileptonic decays of beauty hadrons was measured at mid-rapidity (|y| &lt; 0.8) in the transverse momentum range 1 &lt; pt &lt; 8 Gev/c with the ALICE experiment at the CERN LHC in pp collisions at a center of mass energy sqrt{s} = 7 TeV using an integrated luminosity of 2.2 nb^{-1}. Electrons from beauty hadron decays were selected based on the displacement of the decay vertex from the collision vertex. A perturbative QCD calculation agrees with the measurement within uncertainties. The data were extrapolated to the full phase space to determine the total cross section for the production of beauty quark-antiquark pairs
