El Neoconstitucionalismo y el Estado Constitucional de Derecho han internacionalizado los sistemas jurídicos de cada país, toda vez que los mismos han tenido que ajustar sus normas a las prescripciones supranacionales, sometiéndose al control de los organismos internacionales, tales como la Corte Interamericana de Derechos Humanos, máximo intérprete de la Convención Americana de Derechos Humanos. Es así como los jueces en Colombia, en repetidas oportunidades han fundamentado sus decisiones sobre derechos humanos, en tratados o convenciones internacionales ratificados por Colombia, por tanto, en el presente artículo de investigación se propone como pregunta central ¿Cuál es el alcance del control difuso de convencionalidad en las providencias judiciales en Colombia? Como objetivo general se pretende determinar el alcance del Control de Convencionalidad en las providencias judiciales en Colombia.

Published: August 2020

Conflicts and violence occur in various regions of Indonesia. It due to a lack of mutual understanding and respect between one group to other. Intercultural education was needed to build communication and understanding diversity. This article aims to explain the perceptions of students and educators regarding intercultural education. The research design used a qualitative method. Informants were 40 respondents. In this study,the survey instruments used interviews and questionnaires which contained 3 main components. Data analysis used coding and categorization. Data analysis used interactive analysis which includes data collection, data reduction, and verification to find general patterns. Data validation used the method triangulation by checking through interviews with the respondents.The result showed the most students considered that the direction of intercultural learning was to develop knowledge and sensitivity to social reality. Intercultural learning digitally becomes an opportunity and a challenge. We could utilize learning technology,innovative and creative methods, the efficiency of learning time, provide new perspectives on intercultural learning digitally. Digital media visualized themes and made learning more concrete. Students’ sense of meaning difference increased as a necessity. Differences in background, culture, thought, behavior, environment, level, and religion did not become a problem for students in interacting and communicating.

Published: August 2020

Anemia is a common complication of chronic kidney disease (CKD), and its prevalence has shown a tendency to increase in many countries. Anemia is associated with incident heart failure and increases mortality in CKD patients, garnering public attention. Here, we reviewed recent studies about CKD with anemia, and tried to summarize the risks and causes and new progress in the treatment of renal anemia. Among the risks and causes, calcium and phosphorus metabolism disorders should be pointed out along with common causes such as iron and erythropoietin deficiencies, hypoxia, inflammation and uremic toxins, and so on. The new anti-anemia treatments mainly include hematopoietic materials supplementation, erythropoietin-stimulating agents, calcium and phosphorus regulators and hypoxia-inducible factor prolyl hydroxylase inhibitors.

Published: August 2020

Abstract
Background: Data on student experience of the clinical learning environment in Ghana are scarce. We therefore aimed to assess students’ evaluation of the clinical learning environment and the factors that influence their learning experience.Methods: This was a cross-sectional survey of 225 undergraduate nursing and midwifery students. We used the Clinical Learning Environment and Supervision + Nurse Teacher (CLES +T) evaluation scale to assess students’ experience of their clinical placement. The association between student demographic characteristics and clinical placement experience was determined using t-test or ANOVA.Results: Most of the sampled students were Nurses (67 %) and in the third year of training (81%). More students received supervision from a nurse (57%) during clinical placement and team supervision (67%) was the most common during clinical placement. Nursing students were more likely to rate their clinical experience better than midwifery students (p=0.002). Students who had increased contact with private supervisors were also more likely to rate their experience higher (p=0.002). Clinical experience was also rated higher by students who received successful supervision compared to those who had unsuccessful or team supervision (p=0.001).Conclusion: Team supervision is high in health facilities where students undertake clinical placement in Ghana. Frequent contact with private supervisor and successful supervision are associated with better rating of clinical experience among Ghanaian undergraduate nursing and midwifery students.

Published: August 2020

Abstract
Background

To investigate changes in levels of myokines after regular aerobic training and resistance training in post- menopausal females with obesity.

Methods

A community-based a randomized controlled trial study was 41 post- menopausal females with obesity from Buk-gu community center, Chuncheon, Gangwon-do, Republic of Korea, from November 2017 until the end of October 2018. Among 41 post- menopausal obese females volunteered to participate in this study performed regular physical exercise training (aerobic exercise and resistance exercise). These participants were randomly assigned to one aerobic exercise group (n = 21) and one resistance exercise group (n = 20). The experimental group performed three days of aerobic exercise and resistance exercise per week (i.e., Monday, Wednesday, and Friday) each group. Body composition, physical fitness, and myokines were measured at baseline, 6 weeks, and 12 weeks.

Results

Two-way within-factor ANOVA revealed group × time interaction for body mass index (BMI, P < 0.05). In the resistance exercise group, muscle endurance (P < 0.001), power (P < 0.01), and agility (P < 0.001) were significantly increased at 12 weeks than those at 6 weeks and baseline. In the aerobic exercise group, muscle strength (P < 0.05), flexibility (P < 0.05), muscle endurance (P < 0.001), and agility (P < 0.001) were greater at 12 weeks than those at 6 weeks and baseline. Levels of IL-6 (P < 0.001), IL15 (P < 0.001), and BDNF (P < 0.001) were greater at 12 weeks than those at 6 weeks and baseline in both exercise groups.

Conclusions

Aerobic exercise training and resistance exercise training can change levels of myokines and improve body composition and physical fitness of obese females. These findings provide preliminary evidence that obese females need to exercise or perform physical activity to improve their levels of myokines and physical fitness.

Abstract
Background: Evidence regarding the association between daily steps recommendation and older adults’ lower limb strength is lacking; thus, this study investigated whether taking at least 7,000 steps/day is cross-sectionally and prospectively related to lower-extremity performance in older Taiwanese adults. 89 community-dwelling adults aged over 60 years (mean age: 69.5 years) who attended both baseline and follow-up surveys. Methods: This study used adjusted logistic regression analysis to explore cross-sectional and prospective relationships between their accelerometer-assessed daily steps and lower-extremity performance (five-times-sit-to-stand test). Results: This study found the older adults who took 7,000 steps/day were more likely to have better lower-extremity performance cross-sectionally (odds ratio [OR] = 3.82; 95% confidence interval [CI]: 1.04, 13.95; p = 0.04), as well as to maintain or increase their lower-extremity performance prospectively (OR=3.53; 95% CI: 1.05, 11.84; p = 0.04). Conclusions: Our findings support a minimum recommended level of step-based physical activity for older adults, namely, 7,000 steps/day, as beneficial for maintaining or increasing older adults’ lower-extremity performance.

Published: August 2020

Abstract
Background It remains unclear whether a specific chest CT characteristic is associated with the clinical severity of COVID-19. This meta-analysis was performed to assess the relationship between different chest CT features and severity of clinical presentation in COVID-19.Methods PubMed, Embase, Scopus, web of science databases (WOS), Cochrane library, and Google scholar were searched up to May 19, 2020 for observational studies that assessed the relationship of different chest CT manifestations and the severity of clinical presentation in COVID-19 infection. Risk of bias assessment was evaluated applying the Newcastle-Ottawa Scale. A random-effects model or fixed-effects model, as appropriately, were used to pool results. Heterogeneity was assessed using Forest plot, Cochran's Q test, and I2. Publication bias was assessed applying Egger’s test.Results A total of 18 studies involving 3323 patients were included. Bronchial wall thickening (OR 11.64, 95% CI 1.81- 74.66) was more likely to be associated with severe cases of COVID-19 infection, followed by linear opacity (OR 3.27, 95% CI 1.10- 9.70), and GGO (OR 1.37, 95% CI 1.08- 1.73). However, there was no significant association between the presence of consolidation and severity of clinical presentation (OR 2.33, 95% CI 0.85- 6.36). Considering the lesion distribution bilateral lung involvement was more frequently associated with severe clinical presentation (OR 3.44, 95% CI 1.74- 6.79).Conclusions Our meta-analysis of observational studies suggests some specific chest CT features. The presence of these CT features can help the physicians to early and appropriately approach to the severe and fatal cases of COVID-19.

Abstract
Background: Sperm-associated antigen 9 (SPAG9) has been proposed as a novel biomarker for early diagnosis of human tumors. This study was aimed to assess the clinical value of serum SPAG9 for HCC diagnosis.Methods: Serum SPAG9 was measured by quantitative real-time ploymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA). Chi-square test was applied to evaluate the association between serum SPAG9 mRNA level and clinical characteristics. The diagnostic accuracy of the serum SPAG9 mRNA was assessed using receiver operating characteristic (ROC) curve.Results: Serum SPAG9 level was significantly higher in HCC patients than that in healthy controls at both mRNA and protein levels (P<0.01 for all). Furthermore, serum SPAG9 mRNA level was positively correlated with TNM stage (P=0.047), tumor size (P=0.044), and lymph node metastasis (P=0.014). The area under the curve (AUC) of the ROC curve was 0.794, with a sensitivity of 71.4%, a specificity of 80.4%, suggesting the high diagnostic accuracy of serum SPAG9 mRNA for HCC. The cutoff value was 1.030.Conclusions: Serum SPAG9 is significantly increased in HCC, and positively correlated with aggressive clinical characteristics. SPAG9 may serve as a diagnostic biomarker for HCC.

Published: August 2020

Abstract
X-ray diffraction analysis and ultrasonic measurements of a glass with the pyrope composition were conducted to determine its structural and elastic properties at pressures from 1 atm to 12.9 GPa. Our results indicate that its structural evolution is closely related to changes in the compression wave velocity (VP), shear wave velocity (VS), and Poisson ratio. We observed three modes of pyrope glass compression. Moderate shrinkage in the intermediate-range ordered structure occurred at pressures below 6 GPa. Significant shrinkage in the intermediate-range ordering was observed at pressures between 6 and 9 GPa. We observed changes in the short-range ordered structure at pressures above 9 GPa, which were associated with an increase in the coordination number of tetrahedral cations. The absolute values of VP and VS in pyrope glass are similar to those in magnesium-bearing silicate glasses with enstatite and diopside compositions. However, the velocities are higher than those observed in sodium aluminum silicate glasses with jadeite and albite compositions. This indicates that the velocities are governed by the initial density of a glass, which is determined by its chemical composition. In terms of pressure, the velocity minimum in pyrope glass occurs at ~5 GPa, which is similar to the velocity minima in fully polymerized glasses, such as jadeite and albite. The degree of polymerization in pyrope glass is intermediate, and it has a relatively polymerized network. A drastic increase in velocity was observed when the pyrope glass was subjected to pressures above 7–8 GPa, and the velocity exceeded that observed in silicate glasses. Densification phenomenon, such as an increase in the Al coordination number, was efficiently promoted. This was because the cationic field strength of Mg2+ exceeds those of typical non-network forming cations. Magnesium cations may have an important role in controlling the behavior of silicate glass, and partially melted mantle becomes enriched with Mg under pressure. Studying Mg-bearing aluminosilicate glasses can thus help us to better understand the behavior of magma deep in the interior of the Earth.
Tungsten mineralization during the evolution of a magmatic-hydrothermal system: Mineralogical evidence from the Xihuashan rare-metal granite in South China

Abstract
Tungsten deposits are usually associated with granitic intrusions that record a long and complex evolution of the magmatic-hydrothermal system. However, the genetic link between magmatic-hydrothermal evolution and tungsten mineralization remains unclear. The Xihuashan tungsten deposit in South China, an important vein-type wolframite deposit, is closely associated with greisen and multi-phase intrusive activity that produced biotite granite, two-mica granite, and muscovite granite. From the biotite granite to the two-mica granite to the muscovite granite, micas vary from siderophyllite to lithian siderophyllite, with decreasing K/Rb and Nb/Ta ratios and increasing Rb and Cs contents. The zoned micas in the muscovite granite and greisen display fluorine-depleted rims, reflecting subsolidus replacement by external aqueous fluids. The presence of siderite indicates a Fe-, Mn-, and CO2-rich fluid under reducing conditions. The micas in the greisen have higher-F contents and lower Fe3+/Fe2+ ratios than those in the muscovite granite, suggesting that the fluids contributing to greisen formation had a relatively high-fluorine content and were reduced. The increase of CO2 in the fluid enhanced its ability to unlock W from melts/rocks into fluids. The reducing environment also facilitated the tungsten mineralization. During greisenization, the pH value of the fluid increased, which destabilized the polymeric tungstates to form WO42–. The mixture of W-rich solution and Fe-, Mn-rich external fluid eventually precipitated as vein-type wolframite in favorable locations. An empirical equation (Li2O = 0.0748 × F2 + 0.0893 × F) was introduced for estimating the Li2O contents of hydrothermal micas using the F contents determined by EPMA.

Published: August 2020

Introduction. After the Iraq war, the dust phenomenon has increased in western Iran. Our study aimed to evaluate the effect of the dust phenomenon on the content of heavy metals in raw milk in Ilam province.
Study objects and methods. The dust samples were collected during one year. The concentrations of dust particles were determined with the Enviro Check Laser System, using the Dust Monitor Check. The concentration of heavy metals in dust was determined by using the high volume air samplers and glass fiber filters.
Results and discussion. Heavy metals (lead, arsenic, zinc, copper, and iron) were measured at four sampling sites in raw milk by the atomic absorption method. The mean and standard deviations of dust particulate matter (PM10 and PM2.5) were 105.6 ± 90.5 and 25.9 ± 15.4 μg/m3, respectively. The amounts of arsenic, zinc, lead, and copper were higher in the spring and summer. Lead levels in western and southern regions were higher than those in the east, center, and north.
Conclusion. We found similar trends for arsenic, zinc, copper, and iron in raw milk. Our results showed the potential effect of the dust phenomenon on the presence of heavy metals in raw milk.
