Abstract
Background
The outbreak of coronavirus disease 2019 (COVID-19) is now becoming an enormous threat to public health. The clinical spectrum of COVID-19 is extensive, of which critical cases are with rapid disease progression and high mortality. The aim of our study is to summarize the characteristics of different subtypes and explore risk factors of illness severity for early identification and prompt treatment.

Methods
In this retrospective study, we collected data of patients confirmed COVID-19 in Zhejiang Province from 17 January to 12 February 2020. According to the definition of clinical classification, we divided confirmed cases into four types, and summarize epidemiological and clinical characteristics, laboratory and radiograph findings, treatments, and outcomes, respectively. Moreover, we used univariate and multivariate ordinal logistic regression models to explore risk factors for the severity of illness in patients with COVID-19.

Results
A total of 788 patients were enrolled in our study, of whom 52 cases (6.6%) were mild type, 658 cases (83.5%) were common type, 61 cases (7.2%) were severe type, and 17 cases (2.2%) were critical type. Multivariate ordinal logistic regression demonstrated increasing odds of the severity of illness in patients with COVID-19 associated with male (odds ratio [OR] = 1.7, 95% confidence interval [CI]: 1.2–2.6 P = 0.008), fever (OR = 3.6, 95% CI: 2.1–6.3, P <  0.001), cough (OR = 1.7, 95% CI: 1.0–2.9, P = 0.041), hemoptysis (OR = 3.4, 95% CI: 1.1–10.3, P = 0.032), gastrointestinal symptoms (OR = 1.9, 95% CI: 1.0–3.5, P = 0.047), hypertension (OR = 2.6, 95% CI: 1.2–5.6, P = 0.013). With the increase of age-grading, risk for the severity of illness was gradually higher (≤ 18 years [OR = 1.0], 19–40 years [OR = 12.7, 95% CI: 4.5–36.0, P < 0.001], 41–65 years [OR = 14.8, 95% CI: 5.2–42.1, P <  0.001], ≥ 66 years [OR = 56.5, 95% CI: 17.1–186.5, P < 0.001]).

Conclusions
Clinicians should pay close attention to these features in patients with COVID-19 including older age, male, fever, cough, hemoptysis, gastrointestinal symptoms and hypertension to identify the severity of illness as early as possible.

Abstract
Purpose
Although platelet-rich plasma (PRP) therapy has become an increasingly popular treatment for sports-related injuries, the molecular mechanisms of PRP on tissue healing process remain poorly understood. The aim of the present study was to develop an experimental method quantifying the efficacy of PRP with murine patellar tendon injury model, leading to future elucidation of the mechanisms of PRP on healing processes.

Methods
Full-thickness defects were created in the central third of the murine patellar tendon. The prepared allogenic PRP gel was applied on the defect of the patellar tendon (PRP group), while the remaining mice served as the untreated control group. Mice were sacrificed at 2, 4, 6, 8, and 10 weeks after the operation, with histological sections obtained in each time point (n = 4 / time point / group). Semi-quantitative histological evaluation was performed in accordance with the Bonar score. The variables included in this scoring system were cell morphology, ground substance, collagen arrangement, and vascularity, with higher grades indicating worse tendon structures. In addition, the ratio of the collagen fibers to the entire tendon tissue (FT ratio) was measured using KS400 software as a quantitative histological evaluation.

Results
The total Bonar score in the PRP group was significantly lower than in control group. With regard to the variables in the Bonar score, the vascularity score was significantly higher in the PRP group at 2 and 4 weeks, while the collagen arrangement score was significantly lower in the PRP group at 8 weeks. Based on a quantitative evaluation, the recovery speed of the patellar tendon determined by FT ratio was significantly faster in the PRP group than in the control group at 6 and 8 weeks.

Conclusions
We have developed an experimental method for histological and quantitative evaluation of the effects of PRP on tissue healing using murine patellar tendon injury model. The results of this study suggest that the local application of PRP could enhance the tissue-healing process both directly through action on localized cells and indirectly through the recruitment of reparative cells through the blood flow. Further investigations will be needed to confirm the mechanisms of PRP in tissue-healing processes with the development of this experimental model.

Published: July 2020

AbstractParticular interest in selenium (Se) was generated as a result of clinical studies showing that balanced Se dietary system is very important for many physiological processes. There is no recent information available on the Se content in Egyptian foods. The present study was conducted to measure Se content in different food groups. A cross-sectional study was designed; a total of 87 food items were randomly purchased from the main markets and hypermarkets in Alexandria governorate, then digested by wet ashing procedure and finally analyzed using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The highest mean Se value was obtained in protein-rich food followed by nuts and sweetened products (6.8, 6.2, and 5.89 μg/g respectively) shrimps had the highest value among all studied samples (6.8 μg/g), while the lowest one was in soft cheese (0.0036 μg/g). Selenium content in food groups is strongly correlated with food matrix and composition of food items, soil composition, and fortification process.

PURPOSE: Cancer-related fatigue is a prevalent, debilitating symptom that contributes to increased health care utilization among hospitalized patients. Music therapy is a nonpharmacological intervention that uses active (eg, singing, selecting songs) and passive (eg, listening) techniques. Preliminary evidence from small trials suggests a potential benefit for cancer-related fatigue in the inpatient setting; however, it remains unclear which techniques are most effective. METHODS: A cross-sectional mixed-methods study was performed to compare cancer-related fatigue before and after active or passive music therapy. Cancer-related fatigue was captured via the Edmonton Symptom Assessment Scale fatigue item. Patients were asked to provide postsession free-text comments. RESULTS: A total of 436 patients (mean [standard deviation] age, 62.2 [13.4] years; n = 284 [65.1%] women; n = 294 [67.4%] white; active music therapy n = 360 [82.6%]; passive music therapy n = 76 [17.4%]) with a range of primary malignancies participated. Active music therapy was associated with a 0.88-point greater reduction in cancer-related fatigue (95% CI, 0.26 to 1.51; P = .006; Cohen’s D, 0.52) at postsession as compared with passive music therapy when restricting the analysis to patients who rated their baseline cancer-related fatigue as moderate to severe (ie, ≥ 4; n = 236 [54.1%]). Free-text responses confirmed higher frequencies of words describing positive affect/emotion among active music therapy participants. CONCLUSIONS: In a large sample of inpatient adults with diverse cancer disease types, active music therapy was associated with greater reduction in cancer-related fatigue and increased reporting of positive affect/emotions compared with passive music therapy. Additional research is warranted to determine the specific efficacy and underlying mechanisms of music therapy on cancer-related fatigue.

Monolithic lasers on Si have long been anticipated as an enabler of full photonic integration, and significant progress in GeSn material development shows promise for such laser devices. While there are many reports focused on optically pumped lasers, in this work, we demonstrate electrically injected GeSn lasers on Si. We grew a GeSn/SiGeSn heterostructure diode on a Si substrate in a ridge waveguide laser device and tested it under pulsed conditions, giving consideration to the structure design to enhance the carrier and optical confinement. The peak linewidth of 0.13 nm (0.06 meV) and injection current curves indicated lasing, which was observed up to 100 K with emission peaks at 2300 nm. We recorded a threshold of

ZusammenfassungAnalysebasierte Dienstleistungen stellen einen neuartigen Servicetyp dar. Sie stützen ihre Wertschöpfung im Schwerpunkt auf die Anwendung statistischer Analyseverfahren auf Daten, um es ihren Kunden zu ermöglichen bessere Entscheidungen zu treffen oder komplexere Probleme lösen zu können. Während jedoch ihr Potenzial für neue Wertschöpfungsmöglichkeiten viel diskutiert ist, bleibt das Service Design als Instrument zur Erarbeitung neuer Dienstleistungen in Bezug auf diesen Servicetyp bisher unspezifisch. Als Folge haben Service Design Teams nach wie vor Schwierigkeiten, analysebasierte Dienstleistungen systematisch zu entwickeln. In diesem Beitrag entwickeln wir ein neues methodisches Werkzeug, das Service Designer dabei unterstützt Servicekonzepte analysebasierter Dienstleistungen zu entwickeln. Hierfür stellen wir allgemeingültige Gestaltungsrichtlinien auf und nutzen diese anschließend, um ein neues methodisches Werkzeug – das Analysebasierte-Dienstleistungs-Canvas – vorzuschlagen.

As cidades possuem a capacidade de gerar o seu clima próprio, decorrente das transformações de sua superfície em consonância com seus atributos geoecológicos. Nesse contexto, o trabalho objetiva-se a analisar se o processo de urbanização, associado às mudanças nos padrões de uso e ocupação da terra foram capazes de alterar as condições térmicas no distrito de Carapina – Serra/ES, ao ponto de caracterizar no mesmo a existência de uma ilha de calor atmosférica. Para isso, utilizou-se transects fixos e móveis realizados no verão, sob atuação do sistema anticliclonal semi-fixo da América do Sul (ASAS). Os resultados mostram que as áreas mais aquecidas ficaram bem definidas nos períodos matutinos e vespertinos. Na análise noturna, o campo termal apresentou comportamento homogêneo. A maior amplitude térmica foi observada às 16h00min. De maneira geral, os pontos localizados na porção litorânea apresentaram temperaturas mais amenas em relação ao interior. O diagnóstico confirmou que as mudanças de uso e cobertura da terra, associadas às características do relevo local, bem como à dinâmica de brisas marítimas e terrestres, influenciam diretamente no comportamento térmico do ar atmosférico.

Poland’s policy towards membership in the Economic and Monetary Union
Authors: Kołodziejczyk Katarzyna 
Published: July 2020

Poland’s accession to the European Union determines future membership in the Economic and Monetary Union (EMU). The subject of the research is the analysis of Polish policy towards EMU membership during the first 15 years of Poland’s membership in the EU. The research is political nature and intentionally does not focus on the economic benefits and challenges associated with Poland’s membership in the EMU.
The aim of research is to focus on changes taking place in the policy towards Poland’s membership in the EMU conducted by the ruling parties, successively by the coalition of the Civic Platform (PO) and the Polish People’s Party (PSL) – PO-PSL in years 2007–2015 and then by the Law and Justice (PiS) in years 2005–2007 in consultation with the Self-Defence (Samoobrona RP) and the League of Polish Families (LPR) as well as 2015–2019 in the coalition with the Jarosław Gowin’s Agreement (Porozumienie Jarosława Gowina) and Zbigniew Ziobro’s Solidary Poland (Solidarna Polska).
The main research questions relate to how has Poland’s membership in the EMU been perceived by the ruling parties since 2004 and what are the reasons for the fact that joining the eurozone by Poland until recently had been the strategic goal of the ruling elite of the country, and nowadays the strategic goal has become non-entry into the EMU.
The main research methods were the analysis of the content of documents and a comparative method. The first method allowed presenting the perspective of Poland’s entry into the euro area from the side of the ruling parties policy. That is why the text was mainly based on source materials, i.e. reports, government documents, political speeches, party election programs and press articles. The second research method allowed to compare the concept of Poland’s membership in the EMU presented in various programs of the ruling political parties.
The result of the conducted research indicates the radicalisation of the views of the Polish political scene. It also proves that date of adoption of the single European currency depends not only on meeting the convergence criteria, but also on which political option will rule in Poland.

Published: July 2020

Abstract
The noise of dental turbines is mainly correlated with the anxiety and discomfort of patients and the work safety of the dental professionals. Rotational speed, torque, airflow, and noise have an essential role in the proper performance of dental air turbines. This work aimed to address the following question: how do rotational speed, torque, and airflow correlate with noise in dental high-speed handpieces? Three new air turbines of nine different commercial brands were essayed for rotational speed, torque, noise level (A-weighting), and airflow in agreement with ISO 14457:2017, Dentistry – Handpieces and Motors (27 handpieces) 3 times a day and for 5 days under controlled air pressure. One-way analysis of variance and Tukey’s test (α = 0.05) showed differences among brands for speed, torque, noise, and airflow (210.17–397.93 kr/min, 0.03–0.15 N·cm, 68.80–82.16 dB, and 29.6–37.8 L/min, respectively). Speed (r =–0.7) and airflow (r = –0.6) showed an inverse correlation with noise: the higher the speed, the higher the airflow and the lower the noise. Torque showed no correlation with the speed (r = –0.1). As a conclusion, dental handpieces achieving the maximum airflow and speed can produce lower noise.
