Background
Accurate prediction of the disease severity of patients with COVID-19 would greatly improve care delivery and resource allocation and thereby reduce mortality risks, especially in less developed countries. Many patient-related factors, such as pre-existing comorbidities, affect disease severity and can be used to aid this prediction.

Objective
Because rapid automated profiling of peripheral blood samples is widely available, we aimed to investigate how data from the peripheral blood of patients with COVID-19 can be used to predict clinical outcomes.

Methods
We investigated clinical data sets of patients with COVID-19 with known outcomes by combining statistical comparison and correlation methods with machine learning algorithms; the latter included decision tree, random forest, variants of gradient boosting machine, support vector machine, k-nearest neighbor, and deep learning methods.

Results
Our work revealed that several clinical parameters that are measurable in blood samples are factors that can discriminate between healthy people and COVID-19–positive patients, and we showed the value of these parameters in predicting later severity of COVID-19 symptoms. We developed a number of analytical methods that showed accuracy and precision scores >90% for disease severity prediction.

Conclusions
We developed methodologies to analyze routine patient clinical data that enable more accurate prediction of COVID-19 patient outcomes. With this approach, data from standard hospital laboratory analyses of patient blood could be used to identify patients with COVID-19 who are at high risk of mortality, thus enabling optimization of hospital facilities for COVID-19 treatment.

Published: March 2021

Background and objectives
CKD is an independent risk factor for heart failure. Iron dysmetabolism potentially contributes to heart failure, but this relationship has not been well characterized in CKD.

Design, setting, participants, & measurements
We performed a historical cohort study using data from the Veterans Affairs Corporate Data Warehouse to evaluate the relationship between iron status and heart failure hospitalization. We identified a CKD cohort with at least one set of iron indices between 2006 and 2015. The first available date of serum iron indices was identified as the study index date. The cohort was divided into four iron groups on the basis of the joint quartiles of serum transferrin saturation (shown in percent) and ferritin (shown in nanograms per milliliter): reference (16%–28%, 55–205 ng/ml), low iron (0.4%–16%, 0.9–55 ng/ml), high iron (28%–99.5%, 205–4941 ng/ml), and function iron deficiency (0.8%–16%, 109–2783 ng/ml). We compared 1-year heart failure hospitalization risk between the iron groups using matching weights derived from multinomial propensity score models and Poisson rate-based regression.

Results
A total of 78,551 veterans met the eligibility criteria. The covariates were well balanced among the iron groups after applying the propensity score weights (n=31,819). One-year adjusted relative rate for heart failure hospitalization in the iron deficiency groups were higher compared with the reference group (low iron: 1.29 [95% confidence interval, 1.19 to 1.41]; functional iron deficiency: 1.25 [95% confidence interval, 1.13 to 1.37]). The high-iron group was associated with lower 1-year relative rate of heart failure hospitalization (0.82; 95% confidence interval, 0.72 to 0.92). Furthermore, the association between iron deficiency and heart failure hospitalization risk remained consistent regardless of the diabetes status or heart failure history at baseline.

Conclusions
Iron deficiency, regardless of cause, was associated with higher heart failure hospitalization risk in CKD. Higher iron status was associated with lower heart failure hospitalization risks.

WHENCE THE DEMAND FOR ETHICAL THEORY?
Authors: Cueni Damian , Queloz Matthieu 
Published: March 2021

AbstractWhere does the impetus towards ethical theory come from? What drives humans to make values explicit, consistent, and discursively justifiable? This paper situates the demand for ethical theory in human life by identifying the practical needs that give rise to it. Such a practical derivation puts the demand in its place: while finding a home for it in the public decision-making of modern societies, our account also imposes limitations on the demand by presenting it as scalable and context-sensitive. This differentiates strong forms of the demand calling for theory from weaker forms calling for less, and contexts where it has a place from contexts where it is out of place. In light of this, subjecting personal deliberation to the demand turns out to involve a trade-off.
Realism and Naturalism in Samrat Upadhyay’s The Guru of Love
Authors: Shrivastwa Bimal Kishore 
Published: March 2021

This research project seeks to explore realism and naturalism in Samrat Upadhyay's novel, The Guru of Love, in the context of Nepalese society. It analyses how the novel delineates a realistic account of Nepalese middle-class people's hardships, struggles, and problems they face internally and externally through the character of Ramchandra, the protagonist of the fiction, an ordinary mathematics teacher who faces some hindrances in search of a better life and developing a career in the capital city. The principal objective of the study is to find the realistic, naturalistic, and materialistic elements in the novel, to examine the psychic predispositions that characters come through realistically, and to analyze the role of love and sex in terms of spirituality and emancipation as they all fall into the parameters of naturalism and realism. This study is developed through a theoretical framework based on realism and naturalism for the close textual analysis of the novel. The principal finding of the research paper is that the major characters of the novel, The Guru of Love, suffer from the conflict between their desires and their socio-economic realities. The article also surveys how material prosperity fails to resolve all the problems that human being goes through. It is expected that the paper stands as a reference for the research scholars interested to explore in the area.

The problem of waste is a common problem in the world, in the era of the Industrial Revolution 4.0, ready-to-eat food and beverage products resulted in piles of waste which resulted in environmental pollution. Waste that can damage the environment is waste that cannot be decomposed by nature. As a form of saving the earth to reduce the waste of plastic bottles and glass bottles, the younger generation should be able to use them such as pencil boxes, plastic flower vases, chairs, multipurpose storage places and bross. Meanwhile, waste glass bottles can be made into products such as miniatures, flower pots and home decorations. Permasalahan sampah menjadi masalah bersama didunia, pada era Revolusi Industri 4.0, produk makanan dan minuman kemasan siap saji mengakibatkan timbunan sampah yang mengakibatkan pencemaran lingkungan. Sampah yang dapat merusak lingkungan adalah sampah yang tidak dapat terurai oleh alam. Sebagai bentuk penyelamatan bumi mengurangi limbah botol plastik dan botol kaca, sebagai generasi muda harus dapat memanfaatkan seperti kotak pensil, vas bunga bunga dari plastik, kursi, tempat penyimpanan serbaga guna dan bross.

Published: March 2021

Objective To determine the reliability of common clinical tests for tibialis posterior tendinopathy (TPT) and to investigate their relationship with grayscale ultrasound findings in individuals who have medial foot/ankle pain. Design Prospective cohort. Methods Fifty-two individuals reporting medial foot/ankle pain were clinically examined by 2 physical therapists using 4 clinical tests for TPT: pain on tendon palpation, swelling around the tendon, pain/weakness with tibialis posterior contraction, and pain during or inability to perform a single-leg heel raise (SLHR). Individuals also underwent an ultrasound examination by a sonographer. Physical therapists and the sonographer were blind to each other's findings. Positive ultrasound examination included at least 1 of the following grayscale changes: hypoechogenicity, fibrillar disruption, or thickening of the tendon. For reliability between the 2 physical therapists, we calculated kappa coefficients and 95% confidence intervals (CIs). To assess relationships between clinical and imaging findings, we calculated odds ratios and 95% CIs. Results The SLHR was the most reliable test, with substantial agreement between physical therapists (κ = 0.74; 95% CI: 0.54, 0.93), while the other tests had moderate levels of reliability. Of all clinical tests, the SLHR was most related to grayscale findings on ultrasound (odds ratio = 5.8), but was imprecisely so, with a 95% CI of 1.7 to 20.4. Conclusion Of all tests, the SLHR was the most reliable between clinicians and best related to imaging findings in individuals presenting with TPT, aligning with contemporary thinking of tendinopathy as a load-related clinical presentation. There was a disconnect between clinical findings and ultrasound grayscale changes in the tibialis posterior tendon in individuals with TPT. J Orthop Sports Phys Ther 2021;51(5):253–260.

Published: March 2021

The present fuel cell technology is under considerations as a potential power source for Unmanned Aerial Vehicles. Fuel cells are an electrochemical power plant that takes hydrogen and oxygen as inputs and produces electricity, water and heat as outputs. Most of the global hydrogen production is from non-renewable fossil fuels. Therefore, this paper investigates how to save hydrogen fuel consumption and operate at high efficiency in the fuel cell/battery hybrid system to power a small Aircraft. We achieved that by working on the power management of the fuel cell/battery hybrid propulsion system for small UAV by using the fuzzy logic controller and charging up the batteries. The hybrid propulsion system consists of a 1.2kW PEM fuel cell, three 12V batteries, DC/DC converters, and an electric engine. The fuzzy logic controls the batteries' output powers through the bidirectional DC/DC converter. It will help maintain the fuel cell operates at an optimal point with high efficiency as the main power supply for different flight phases to achieve the desired power.
Does Deportation Infringe Rights?
Authors: Draper Kaila 
Published: March 2021

Consider the migrant who illegally crosses an international border, and suppose that agents of the state she has entered apprehend and detain her, and then forcibly return her to her country of origin. Some opponents of aggressive deportation policies believe that, barring unusual circumstances, this process of using coercion and force to expel the migrant is an infringement of the migrant’s rights. Many of those who disagree contend that, because a state has a right to enact and enforce immigration restrictions, most deportations do not infringe rights. This paper takes the position that, absent an adequate argument to the contrary, one can conclude presumptively that the typical deportation is an infringement of the migrant’s rights. Its primary aim is to show that certain serious arguments to the contrary are inadequate.
recommendation to the SSH community: Take a linguist on board
Authors: Beeken Jeannine 
Published: March 2021

In this paper we address how Natural Language Processing (NLP) approaches and language technology can contribute to data services in different ways; from providing social science users with new approaches and tools to explore oral and textual data, to enhancing the search, findability and retrieval of data sources. By using linguistic approaches we are able to process data, for example using Automated Speech Recognition (ASR) and named entity recognizers (NER), extract key concepts and terms, and improve search strategies. We provide examples of how computational linguistics contribute to and facilitate the mining and analysis of oral or textual material, for example (transcribed) interviews or oral histories, and show how free open source (OS) tools can be used very easily to gain a quick overview of the key features of text, which can be further exploited as useful metadata.
Preoperative Left Ventricular Remodeling Based on Echocardiographic Findings in Patients with Ischemic Mitral Regurgitation
Authors: Rudenko S. A. , Potashev S. V. , Verich N. M. 
Published: March 2021

Ischemic mitral regurgitation (IMR) is a dynamic phenomenon depending on myocardial function and he- modynamics. Grade, hemodynamic significance and anatomic reasons of IMR are always key features for defining indica- tions for surgical treatment. In chronic IMR diagnosis, the emphasis is upon mitral regurgitation (MR) mechanisms and its hemodynamic consequences.
The aim. To study preoperative echocardiographic features of left ventricular (LV) remodeling and IMR, and retro- spectively define their influence upon the choice of IMR surgical correction method.
Materials and methods. We performed surgical correction of IMR in 292 patients over the period from January 2012 to December 2019 at the National Amosov Institute of Cardiovascular Surgery. All the patients were divided into 2 groups depending on MR surgical correction method. Group 1 included 141 patients who underwent valve-sparing sur- gery. Group 2 included 151 patients after prosthetic mitral valve replacement. All the patients underwent comprehensive echocardiography prior to surgery.
Results and discussion. The patients of Group 2, who underwent prosthetic mitral valve replacement showed sig- nificantly more marked eccentric LV remodeling, namely significantly higher LV EDI (p=0.02) and ESI (p=0.0027) with significantly worse LV global contractility: compared to Group 1, almost twice bigger proportion of patients in Group 2 had severely decreased LVEF ≤30% (p=0.047), while mean LVEF corresponded with moderate LV systolic dysfunc- tion (LVEF≤45%), and in Group 1 the majority of patients had mild-to-moderate LV systolic dysfunction (LVEF ≥45% and ≥35%, respectively, p=0.016) with significantly higher proportion of patients with preserved LVEF (p=0.039). This caused marked remodeling in Group 2 patients, lead to impossibility of valve-sparing MV plastics and brought up neces- sity of prosthetic MV replacement, which is aligned with available evidence on poor prognosis markers and reverse left chambers remodeling in functional secondary MR, including IMR.
Conclusions. Significantly more marked LV remodeling and more severe systolic dysfunction lead to more severe IMR with more marked MV valvular morphology alterations and more frequent MV replacement. Our data witness in favor of earlier surgical intervention in coronary artery disease (CAD) patients with IMR aiming at successful valve-sparing IMR correction.
