Abstract
Several reports associated the severe Coronavirus disease-2019 (sCOVID-19) with secondary-haemophagocytic lymphohistiocytosis (sHLH) and proposed the HScore table for sCOVID-19 patients. We conducted a meta-analysis to found the possible association of HScore parameters with severity in COVID-19 patients. Systematic search was performed in Medline (PubMed), EMBASE, and Cochrane databases using all HScore and COVID-19 keywords. The records were screened based on inclusion/exclusion criteria. Random/fixed-effect models were employed. The pooled mean differences were estimated for continuous parameters. The pooled odds-ratio was estimated for fever. Eighteen studies met the criteria and included in the meta-analysis (2459 patients). Significant higher levels of leukocyte, neutrophil, aspartate-transaminase (AST), ferritin, and fibrinogen, as well as lower level of lymphocyte, platelet, and hemoglobin were found in sCOVID-19 patients compared to non-severe ones. Fever was nearly associated with 2 times increased odds of sCOVID-19 (p-value = 0.051). Lymphopenia, thrombocytopenia, hypohemoglobinemia, hyperferritinemia, high levels of AST, and fever are common features of both sCOVID-19 and HLH. However, leukocytosis, neutrophilia, and hyperfibrinogenemia found in sCOVID-19 contrast with HScore. Conclusively, HScore parameters could be risk factors for the severity of COVID-19. However, some parameters’ roles are contradictory, suggesting further investigation and a new way of HScore interpretation for sCOVID-19 patients.

Objective:
The aim of this study was to describe the clinical characteristics of patients that have had a heart failure with preserved ejection fraction (HF-pEF) and to identify the factors associated with 5-year mortality and readmission.

Methods:

A prospective cohort study was conducted of patients followed by the Heart Failure Unit of the Internal Medicine Department. Clinical characteristics and outcomes were collected. Univariate and multivariate analyses were performed in order to identify factors associated with 5-year mortality and readmission.

Results:
A total of 209 patients with HF-pEF were followed, 59.3% of these were women, with a mean age 79 years. The main etiology was hypertensive heart disease and a high level of comorbidity (chronic renal failure, hypertension and atrial fibrillation) was observed. The 5-year mortality was 55.5%; the related variables were anemia (hazard ratio [HR]=1.7; 95% confidence interval [CI]: 1.2-2.5), in patients being treated with statins (HR=0.7; 95%CI 0.5-0.9) and spironolactone (HR= 1.6; 95% CI: 1.1-2.3); 24.5% of patients had >2 admission in 5 years, with the main related factors being atrial fibrillation (HR=2.7; 95%CI: 1.4-5.5), anemia (HR=1.9; 95%CI:1.0-3.3) and were being treated with spironolactone (HR=2.1; 95%CI:1.2-3.7).

Conclusion:

Patients with HF-pEF are old and present a high level of comorbidity. Furthermore, they have a high 5-year mortality and readmission rate. The only factor associated with lower mortality was the treatment with statins. The use of spironolactone was associated with a higher mortality risk.

Published: August 2020

Purpose:
The aim was to report on the visual outcomes and safety of myopic LASIK performed in patients with corneas of central thickness below average(<540μm) and normal topography.

Methods:
This is a retrospective cohort study conducted at a private practice setting on Mexican Hispanic patients who underwent myopic LASIK between January 2014 and January 2015. An analysis of records of patients >18 years-old with previous normal topography, stable refraction, corrected visual acuity ≥ 20/20 (Snellen), Central Corneal Thickness (CCT) < 540μm and at least 12 months follow up after surgery was conducted. The main outcome measures were standard visual outcomes (efficacy, safety, refractive stability) and Percent Tissue Altered (PTA) analysis was conducted.

Results:
A total of 51 patients (102 eyes) were included; 56% (n=57) were female. The mean age was 26.52 ± 8.06 (range 18-55 years) with a mean follow up of 13.9 ± 1.2 months. Preoperative CCT was 515.44 ± 17.87μm (range 452- 540μm), with a mean refractive spherical equivalent (SEQ): -4.08 ± 2.17 D (range -0.75 to -9.75 D), and mean refractive cylinder: -1.44 ± 1.29 D (range 0.00 to -6.00 D). Mean predictability of postoperative SEQ was -0.20 ± 0.40 D (range -1.25 to +1.25). Postoperative SEQ was ±0.50 D in 71%, ±1.00 D in 93% of the eyes. Postoperative uncorrected distance visual acuity was ≥20/20 in 78% and ≥20/25 in 95%. One line of CDVA was lost in 3% of the eyes, no eyes lost ≥2 lines. No ectasia cases were observed during follow-up.

Conclusion:
LASIK surgery in Mexican Hispanic patients with thinner than “normal” corneas (<540 μm) is safe, efficient and predictable at 1 year follow up for myopic refractive corrections with no evidence of postoperative keratectasia.
Comparisons Between Braking Experiments and Longitudinal Train Dynamics Using Friction Coefficient and Braking Pressure Modeling in a Freight Train
Authors: Choi Don Bum , Jeong Rag-Gyo , Kim Yongkook , Chai Jangbom 
Published: August 2020

Background:
This paper describes the predictions and validation of the pneumatic emergency braking performance of a freight train consisting of a locomotive and 20 wagons, generally operated in Korea. It suggests the possibility of replacing the expensive and time-consuming train running tests with longitudinal train dynamic simulations.

Methods:
The simulation of longitudinal train dynamics of a freight train uses the time integration method of EN 14531. For reasonable simulation results, the characteristics of the train and brake equipment must be considered. For the train characteristics, specifications provided by the vehicle manufacturer are used. The braking characteristics are analyzed by friction coefficient tests and a braking pressure model. The friction coefficients of a locomotive and wagons are tested with a dynamo test bench and statistically expanded to account for variability. Freight trains should take into account the braking delay time. To reflect this in the simulation, the brake cylinder pressure pattern model uses pressures and exponential empirical equations measured at selective positions in a train of 50 vehicles. The simulation results are validated in comparison with those of the braking tests of a freight train consisting of 1 locomotive and 20 wagons.

Results:
The results of the longitudinal dynamics simulation show very similar results to the running test results based on the speed profile and braking distance.

Conclusion:
In particular, the statistical expansion method of the friction coefficient enables robust prediction of the distribution of the braking distance. The simulation can reduce or make up for costly and time-consuming repeated braking tests and reduce the risks that may arise during testing.

José Enrique Rodó: The Birth of Latin America Out of Spiritual Revolt
Authors: Schelkshorn Hans 
Published: August 2020

Abstract
In the second half of the 19th century positivism became the official state doctrine of many countries in southern America. Around 1900, however, the authoritarian positivistic regimes were increasingly criticized due to their cultural imitation on the Anglo-Saxon world and the atheistic ideology. In this context, José Enrique Rodó, a poet and philosopher of Uruguay, called for a critical and creative re-adoption of the “Latin” roots of southern America, specifically Greek culture and early Christianity. In his essay “Ariel” (1900), Rodó sparked a spiritual revolt that especially affected the youth of the whole continent. In contrast to Nietzsche but on the basis of secular reason, Rodó defended a religion of love, which inspired important philosophies in the 20th century, from José Vasconcelos and Antonio Caso to the theologies and philosophies of liberation. Thus, “Latin America” as a self-designation of the South American peoples was essentially inaugurated through the spiritual revolt initiated by José Enrique Rodó.
(B)Orders of Immobility
Authors: Echchaibi Nabil 
Published: August 2020

Abstract
Against the promise of free movement and mobility celebrated by the narrative of capitalism and globalization, the border stands as a stark reminder of the terrorizing history of death, destruction, and humiliation at the frontier. Like the Atlantic Ocean, home of the invisible and brutalizing memory of the slave trade, the Mediterranean and the Sonoran Desert today have become a dead zone, a dark trail of loss and sufferance amidst faint dreams of open lands and seas and freedom to roam. The growing militarization and securitization of the border unleashed by sophisticated technologies and algorithms of surveillance reflect a disturbing precariousness of empathy which seeks to conceal and banalize the trauma of crossing frontiers. By framing the debate of borders around security, threat and territory, the narrow calculus of border thinking multiplies and mutates beyond the physical spaces of the frontier, animating in the process a narrative of invasion, cultural purity, and territorial privilege. This article offers a critical reading of the politics, performance, and poetics of the border, border practices and border thinking in our current fractious conjuncture. Using the works of Caribbean poet and philosopher Edouard Glissant, I argue for a different interpretation and poetics of the border, one which does not nullify rootedness but refutes the tyranny of the “totalitarian root”. Under this alternative imaginary, the degeneration of borders into zones of non-being and the converse image of mobility as a human right force us to re-visit old fundamental questions about the distribution of the earth.
Concepts and Dimensions of Human Dignity in the Christian Tradition
Authors: Müller Sigrid 
Published: August 2020

Abstract
This paper investigates the extent to which Christian tradition can be used to support human dignity and human rights in contemporary society. It explores the Christian tradition for ideas that correspond to the four main dimensions of human dignity: anthropological, moral, legal, and practical. It examines how these dimensions relate to the two main Christian perspectives that define human dignity, namely the imago Dei paradigm and dignity of the human soul or person. Concluding observations demonstrate that the corresponding Christian ideas offer a solid foundation for developing a strong Christian narrative and engagement in support of human dignity and human rights. However, an analysis of the two dominating concepts also indicates that a reception that excludes the universal aspect of the imago Dei paradigm can endanger a full acceptance of human dignity and human rights. Therefore, it is necessary to continue existing ecumenical efforts to create a complementary reading of the two traditions.

Landslide is a disaster that can harm properties and souls. Losses due to landslide can be minimized if there are known signs of landslide.. In this research, the landslide indicator is known through the analysis of the magnetic susceptibility of topsoil. This research is a case study conducted at Bukit Sula, Talawi District, Sawahlunto City.Soil samples were taken from two locations in Sula Hill, which are vegetated location (location A) and unvegetated location (location B). This research’s samples took with downward vertical of each 100 m was taken with a space range of 5 m, so that is obtained 21 sampling points at each of these locations. Measurement of magnetic susceptibility value using Bartington Magnetic Susceptibility Meter measured at two frequencies, namely low frequency of 0.465 kHz (χLF) and high frequency of 4.65 kHz (χHF). At location A the obtained average value of χLF is 804.05×10-8 m3kg-1while the average value of χHF is 804.25×10-8 m3kg-1. At location B the obtained average value of χLF is 9.85×10-8 m3kg-1, while the average value of χHF is 9.64×10-8 m3kg-1. XRF test result showed that magnetic minerals in samples at both locations a hematit (Fe2O3). Based on the comparison of susceptibility value and concentration of hematite and quartz minerals between sample of location A and location B, it can be said that location B has been eroded. Based on the presence of superparamagnetic grain, the samples taken from location B have finer grains than the samples at location A. Scanning Electron Microscope (SEM) also shows that sample B has finer grains than the sample B. These are because location B is an area without vegetation, causing rain drop directly into the soil and can decrease the level of soil grain attachment. Therefore, location B more likely occurred landslide than location A.

Surface Flow and Erosion of Plant Closure of Nusantara Superior Teak (JUN) UNB Experimental Garden, Cogreg, Bogor The study results showed that the amount of rainfall was 1862.40 m3/ha and the volume of runoff occured was 387.20 m3/ha or 20.79 % and the amount of erosion occured 780.52 kg/ha or 0.78 ton/ha or 0.57 m3/ha. This showed that the nusantara superior teak plants (JUN) not optimally hold erosion. This sthappened because the plants was only four years, old so the root was not so deep and the infer cropping plant just harvesed. While erosion was still below the threshold limit. Regression analysis showed that the relationship of rainfall and the long rain runoff was very close relasionship to the value of r = 0.93 with R2 value of 86.5 %, while for the erosion having the r value of = 0.903 and R2 = 81.5 % . This means that 86.5 % rainfall and long of rains affected runoff and 81.5 % against erosion. From the linear regression analysis showed that the one- unit change in rainfall and long rains would cause changes in flow accretion of 0.31 m3 and erosion of 2,661 kg/ha erosion.Keywords : Teak Superior archipelago, Erosion, Surface Flow ABSTRAK Hasil penelitian menunjukkan bahwa jumlah curah hujan adalah 1862,40m3/ha dan volume aliran permukaan yang terjadi adalah sebesar 387,20m3/ha atau 20,79 % dan jumlah erosi yang terjadi adalah sebesar 780,52 kg/ha atau 0,78 ton/ha atau 0,57 m3/ha. Ini menunjukkan bahwa tanaman jati unggul nusantara (JUN) belum secara maksimal untuk menahan laju aliran permukaan yang terjadi.Hal ini disebabkan anaman jati tersebut baru berumur empat tahun. Sehinggan sistem perakarannya belum begitu dalam dan tanaman tumpangsarinya baru dilakukan pemanenan. Sedangkan erosi yang terjadi masih di bawah ambang batas. Analisis regresi menunjukkan bahwa hubungan curah hujan dan lama hujan terhadap aliran permukaan adalah sangat erat dengan nilai r =0,93 dengan nilai R2 86,5% , sedangkan untuk erosi nilai r = 0,903 dan R2 =81,5%. Ini berarti bahwa 86,5% curah hujan dan lama hujan berpengaruh terhadap aliran permukaan dan 81,5% terhadap erosi yang terjadi. Dari analisis regresi linier menunjukan bahwa dengan perubahan satu – satuan curah hujan dan lama hujan akan menyebabkan perubahan pertambahan 0,31 m3 aliran permukaan dan 2,661 kg/ha erosi.Kata kunci : Jati Unggul Nusantara, Erosi, Aliran Permukaan
