Sistema super inductivo en edema óseo. Revisión bibliográfica

Introducción. El edema óseo se produce por una inflamación de la parte interna del hueso provocada por la acumulación de líquidos y sangre (glóbulos rojos, blancos y plaquetas) produciendo así el edema. Puede tener diferentes orígenes cómo traumatismos (fracturas), sobrecarga continuada o incluso por una lesión degenerativa. El síntoma principal es un dolor localizado en la zona del hueso afectado debido al aumento de presión provocado por el acúmulo de líquidos. Objetivo/s. Observar si el sistema super inductivo tiene un efecto positivo en el tratamiento del edema óseo. Material y métodos: Se realizó la búsqueda bibliográfica en cuatro bases de datos diferentes,utilizando las palabras clave junto a los operadores booleanos OR y AND. Mediante los filtros aplicados y siguiendo los criterios de inclusión y exclusión, se han obtenido 7 artículos. Resultados. El tratamiento con el campo electromagnético pulsado ha resultado ser útil en la consolidación ósea y en aumentar de la densidad ósea después de una fractura y al mismo tiempo disminuye el tiempo de tratamiento. Además, según algunos estudios, ayuda en la disminución del edema, pero se necesita más investigación para demostrar su eficacia. Conclusión: Se pueden observar resultados favorables en la consolidación ósea. Sin embargo, se necesita investigación para demostrar la eficacia del sistema super inductivo en el edema óseo.Introduction. Bone edema is caused by an inflammation of the internal part of the bone caused by the accumulation of fluids and blood (red and white blood cells, and platelets), thus producing edema. It can have different origins such as trauma (fractures), continuous overload or even a degenerative injury. The main symptom is localized pain in the area of the affected bone due to increased pressure caused by the accumulation of fluids. Objective/s. Observe if the super inductive system has a positive effect in the treatment of bone edema. Material and methods. The bibliographic search was carried out in four different databases, using the keywords together with the Boolean operators OR and AND. Through the applied filters and following the inclusion and exclusion criteria, 7 articles have been obtained. Results. Treatment with the pulsed electromagnetic field has proven to be useful in bone consolidation and in increasing bone density after a fracture and at the same time decreases the treatment time. Also, according to some studies, it helps in decreasing edema, but more research is needed to prove its effectiveness. Conclusion. Favorable results can be observed in bone consolidation. However, research is needed to demonstrate the efficacy of the super inductive system on bone edema

Iron absorption from iron-biofortified sweetpotato is higher than regular sweetpotato in Malawian women while iron absorption from regular and iron-biofortified potato is high in Peruvian women

Background: Sweetpotato and potato are fast-maturing staple crops and widely consumed in low- and middle-income countries. Conventional breeding to biofortify these crops with iron could improve iron intakes. To our knowledge, iron absorption from sweetpotato and potato has not been assessed. Objective: The aim was to assess iron absorption from regular and iron-biofortified orange-fleshed sweetpotato in Malawi and yellow-fleshed potato and iron-biofortified purple-fleshed potato in Peru. Methods: We conducted 2 randomized, multiple-meal studies in generally healthy, iron-depleted women of reproductive age. Malawian women (n = 24) received 400 g regular or biofortified sweetpotato test meals and Peruvian women (n = 35) received 500 g regular or biofortified potato test meals. Women consumed the meals at breakfast for 2 wk and were then crossed over to the other variety. We labeled the test meals with 57Fe or 58Fe and measured cumulative erythrocyte incorporation of the labels 14 d after completion of each test-meal sequence to calculate iron absorption. Iron absorption was compared by paired-sample t tests. Results: The regular and biofortified orange-fleshed sweetpotato test meals contained 0.55 and 0.97 mg Fe/100 g. Geometric mean (95% CI) fractional iron absorption (FIA) was 5.82% (3.79%, 8.95%) and 6.02% (4.51%, 8.05%), respectively (P = 0.81), resulting in 1.9-fold higher total iron absorption (TIA) from biofortified sweetpotato (P < 0.001). The regular and biofortified potato test meals contained 0.33 and 0.69 mg Fe/100 g. FIA was 28.4% (23.5%, 34.2%) from the regular yellow-fleshed and 13.3% (10.6%, 16.6%) from the biofortified purple-fleshed potato meals, respectively (P < 0.001), resulting in no significant difference in TIA (P = 0.88). Conclusions: FIA from regular yellow-fleshed potato was remarkably high, at 28%. Iron absorbed from both potato test meals covered 33% of the daily absorbed iron requirement for women of reproductive age, while the biofortified orange-fleshed sweetpotato test meal covered 18% of this requirement. High polyphenol concentrations were likely the major inhibitors of iron absorption. These trials were registered at www.clinicaltrials.gov as NCT03840031 (Malawi) and NCT04216030 (Peru)

Energy Performance and Control Strategy for Dynamic Façade with Perovskite PV Panels—Technical Analysis and Case Study

Effective implementation of renewable energy sources (RES) is one of the main challenges in regard to the organization of local energy microgrids with buildings. One of the solutions is the use of dynamic building façades with photovoltaic (PV) panels, in particular the innovative perovskite solar cells (PSCs). This paper describes a case study performed on a pilot installation of perovskite PV panels located in Poland, Central-Eastern Europe. Results of preliminary measurements on this installation are provided in terms of verifying its energy efficiency and the possibility of selecting settings for the façade dynamics control system. Our experiments have considered the sun-tracking mechanism and its energy consumption as well as the impact of weather conditions at different times of the year. The energy efficiency results for the PV system, with average levels below 10%, are rather low. Therefore, even small energy savings in the operation of the PV system itself are significant. Changes in control scenarios for sun-tracking have been proposed and have obtained a reduction from 5% to 1% of energy consumption in autumn and from almost 3.2% to 0.6% in spring, in relation to overall energy produced by the PV system. The need for further experimental research from the perspective of the development and extension of the analyzed installation is pointed out as well
