Diseño e implementación de un prototipo de telecontrol de una secadora de cacao con interfaz web mediante uso de hardware y software libre

En la actualidad existen diversas máquinas secadoras de cacao, que permiten a los agricultores extraer la humedad del producto para su venta, sin embargo no se ha aprovechado los beneficios de la tecnología para mejorar el rendimiento de dichas máquinas, con lo cual el usuario sería capaz de automatizar los sistemas que se usan para el secado, dándole la capacidad de controlar y monitorear en todo momento las operaciones necesarias con tan solo usar un dispositivo móvil y obtener reportes de los procedimientos llevados a cabo en el sistema. Esto permitiría mejorar la calidad del producto y reducir considerablemente el tiempo necesario para procesar el cacao. El objetivo del proyecto es implementar dicho sistema utilizando software y hardware libre de tal manera que el producto final sería de bajo costo.Currently there are several cocoa beans dryer machines, that allow farmers to remove humidity from the product tobe sold, however technology hasn’t been exploited to improve the performance of these machines, allowing the user to automate the systems used for drying, giving him the ability to monitor and control at any time the operations required by simply using a mobile device and receive reports of the entire procedures performed in the system. This will improve product quality and will reduce the time required to process cocoa. The objective of this project is to implement such system using open source software and open hardware, such that the final product would be inexpensive

Radiofrecuencia térmica en alivio del dolor lumbar de origen facetario. Resultado de una serie de casos

Background: Low back pain is the most common causes of medical consultation, being responsible for 10-15% of labor incapacity. In Colombia is third cause of consultation in the hospital emergency department, the leading cause of job relocation and second cause of disability pensions. The importance of evaluating the effectiveness of different therapeutic measures is important; how radio-frequency to relief of pain.Objective: To describe clinical, therapeutic and evolutionary data of the medial branches thermal radiofrequency in the relief of low back pain of facet origin.Methods: Was a cross-sectional study from a cohort of patients with lumbar facet pain. Subject was treatment with thermal radiofrequency. The first control was taken from the first month, then every three months up to a year after treatment. A procedure was considered successful when there was a reduction in pain of 50% or more.Results: The procedure was success in 80% of patients at the first month; the success of the procedure was progressively decreasing over time; 3 months (70%), 6 (61%), 9 (44%), and 12 (diminish to 25%). It was reported as an adverse effect an initial increase of pain in a patient and other patients with the sensation of diminished of the leg strength that disappeared during the first week.Conclusions: The thermal radiofrequency of the medial branches reduce chronic low back pain of facet origin. The improvement gradually decreases. The low incidence of side effects and radiofrequency complications justify its use.Introducción: El dolor lumbar es causa frecuente de consulta médica, responsable de 10-15% de incapacidades laborales. En Colombia es la tercera causa de consulta en servicios de urgencias, la cuarta en medicina general, la primera causa de reubicación laboral y la segunda de pensiones por invalidez, por esto la importancia de evaluar la efectividad de diferentes medidas terapéuticas, como la radiofruencia, para alivio de esta clase de dolor.Objetivos: Describir los datos clínicos, terapéuticos y evolutivos a corto plazo de la radiofrecuencia térmica de los ramos mediales en el alivio del dolor lumbar de origen facetario.Métodos: Se realizó un estudio transversal de la cohorte de pacientes con dolor lumbar facetario sometidos a radiofrecuencia térmica. Se analizaron variables demográficas y clínicas; se evaluaron en el primer control al mes y controles trimestrales, hasta un año de seguimiento. Se calificó como mejoría al procedimiento aquel paciente que con disminución del dolor <50% con respecto al basal.Resultados: El procedimiento fue efectivo en 80% de los pacientes; disminuyó progresivamente con el tiempo: 3 meses (70%), 6 (61%), 9 (44%) de mejoría y 12 (disminuyó a 25%). Como efectos adversos, un paciente refirió incremento inicial del dolor y otro sensación de disminución de la fuerza de las piernas que desapareció durante la primera semana.Conclusiones: La radiofrecuencia térmica de los ramos mediales disminuye el dolor lumbar crónico de origen facetario. La mejoría se reduce gradualmente. La baja incidencia de efectos colaterales y complicaciones de la radiofrecuencia justifican su utilización

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

Toxin distribution and sphingoid base imbalances in Fusarium verticillioides-infected and fumonisin B1-watered maize seedlings

Fusarium verticillioides is a major maize pathogen and there are susceptible and resistant cultivars to this fungal infection. Recent studies suggest that its main mycotoxin fumonisin B1 (FB1) may be involved in phytopathogenicity, but the underlying mechanisms are mostly still unknown. This work was aimed at assessing whether FB1 disseminates inside the plants, as well as identifying possible correlations between the maize resistant/susceptible phenotype and the unbalances of the FB1-structurally-related sphingoid base sphinganine (Sa) and phytosphingosine (Pso) due to toxin accumulation. Resistant (RH) and susceptible hybrid (SH) maize seedlings grown from seeds inoculated with a FB1-producer F. verticillioides and from uninoculated ones irrigated with FB1 (20 ppm), were harvested at 7, 14 and 21 days after planting (dap), and the FB1, Sa and Pso levels were quantified in roots and aerial parts. The toxin was detected in roots and aerial parts for inoculated and FB1-irrigated plants of both hybrids.However, FB1 levels were overall higher in SH seedlings regardless of the treatment (infection or watering). Sa levels increased substantially in RH lines, peaking at 54-fold in infected roots at 14 dap. In contrast, the main change observed in SH seedlings was an increase of Pso in infected roots at 7 dap. Here, it was found that FB1 disseminates inside seedlings in the absence of FB1-producer fungal infections, perhaps indicating this might condition the fungus?plant interaction before the first contact. Furthermore, the results strongly suggest the existence of at least two ceramide synthase isoforms in maize with different substrate specificities, whose differential expression after FB1 exposure could be closely related to the susceptibility/resistance to F. verticillioides.Fil: Arias, Silvina Lorena.

Screen use, sleep duration, daytime somnolence, and academic failure in school-aged adolescents

In this study, we examined the relationship between screen time use, sleep characteristics, daytime somnolence, and academic performance in school-aged adolescents. We surveyed 1,257 12- to 18-year-old adolescents attending 52 schools in urban or suburban areas of Argentina. We recorded the daily exposure to various screen-based activities, including video- and online-gaming, social media, TV or streaming. Screen time and device type in the hour before bedtime, sleep patterns during weekdays and weekends, somnolence (Pediatric Daytime Sleepiness Scale score), and grades in language and mathematics were also assessed. Structural Equation Modelling was used to identify a path connecting the latent variables. Results are expressed as standardized regression weights (srw). Missing data were present in 393 subjects, and thus the final sample consisted of 864 complete responses. Daytime somnolence (i.e., PDSS score ≥ 15) was observed in 614 participants (71%), and academic failure (i.e., grades < 7/10) in 352 of them (41%). Time spent using video gaming consoles was negatively associated with sleep duration (srw = -0.22, p<0.01) and positively connected with daytime somnolence (srw = 0.11, p<0.01). Use of mobile devices was associated with lower academic performance (srw = -0.11, p<0.01). Sleep duration was inversely related to daytime somnolence (srw = -0.27, p<0.01), which was in turn negatively associated with academic performance (srw = -0.18, p<0.05). Bedtime computer use did not influence any outcome. In summary, among adolescents, screen use adversely affected nighttime sleep, daytime somnolence, and academic performance. These findings call for the implementation of educational public campaigns aimed at promoting healthy sleep and reducing screen exposure among adolescents.Fil: Pérez Chada, Daniel.
