Published: October 2020

Aim

Aortic valve replacement (AVR) using sutureless prosthesis is a reasonable alternative in those patients with aortic stenosis who would benefit from reduced cross clamp time, such as elderly and high-risk patients. Actually, excellent performances have been demonstrated in hemodynamic outcomes and safety, but some questions remain open regarding long-term durability and the need for postoperative pacemaker implantation.

Methods

Between January 2014 and August 2019, all 436 patients [male 40.6%, median age 78 years interquartile range (73–82)] treated with sutureless AVR with a Perceval prosthesis were included in our analysis.

Results

The univariate logistic regression showed previous aortic valve surgery [P = 0.028; odds ratio (OR) 3.248], dialysis (P = 0.036; OR 6.435), renal insufficiency (P = 0.021; OR 2.75), EuroSCORE II (P = 0.016; OR 1.051) and year of operation (P < 0.01; OR 0.658) as factors associated with the development of atrioventricular type II or type III block or junctional block requiring pacemaker implantation. The overall incidence of pacemaker implantation after sutureless AVR was 7.1% in the current study, but it dropped to 3.8 and 4.7%, respectively, in 2018 and 2019.

Conclusion

The Perceval aortic valve is associated with encouraging postoperative results. The incidence of pacemaker implantation is strictly linked to the surgeons’ experience, decreasing year by year after an adequate sizing, reaching a percentage comparable with sutured valve.
Financial development and income inequality
Authors: Weychert Ewa
Published: October 2020

This paper analyses the influence of financial development on income inequality. Throughout this work, one may find the overview of theoretical and empirical literature as well as the empirical model using fixed panel data method. This research paper tries to disentangle the opposing views on the relationship between finance and income distribution, by evaluating the impact of the different dimensions of financial development on the level of income inequality. The important added value of this research is the usage of quintiles of income distribution as a dependent variable that may help to recognise the effect of financial development on the poorest and richest. Another novelty of the paper is the consideration of the effects of financial variables on Gini coefficient in the long and short run. The main results of the analysis using dataset from 2003 to 2014 indicate that financial access decreases income inequality.
The Covid-19 pandemic: collective action and European public policy under stress
Authors: Kovac Mitja , Elkanawati Amira , Gjikolli Vita , Vandenberghe Ann-Sophie
Published: October 2020

The European continent faces an apocalyptic pandemic that poses mortal danger to millions of citizens. This paper seeks to address the role played by European public policy in addressing the Covid-19 pandemic. Currently, each Member State across Europe is applying its own measures to deal with the coronavirus; namely, decentralised decision-making that could trigger political tensions among the states. The paper argues that European public policy must change rapidly and fundamentally if these tensions are to be successfully managed; otherwise, such policy might simply cease to exist. Moreover, the known and notorious problem of collective action, information asymmetries, irrationality, negative externalities and the related free-riding phenomenon persistently are distorting the Member States’ combined efforts, resulting in deficient attempts to contain the spread of Covid-19. The paper also argues that the current unprecedented outbreak of this superspreading virus calls for a bigger EU-wide coordinated response. We argue that the Covid-19 pandemic is a good example of an area in which the central EU level holds a comparative advantage over lower levels of government. In addition, the paper offers several substantive insights into ways to improve the public policy response in the ‘war’ against Covid-19.
Theories behind a nursing intern's error in terms of clinical decision-making
Authors: Wu Meng
Published: October 2020

Clinical decision-making and judgment is an essential skill that should be acquired by nursing interns. However, many studies reveal that a large proportion of nursing interns have difficulty in meeting the basic expectation of clinical decision-making. This article begins with a brief review of some theories related to clinical decision-making. Then it takes a case, for example, to show how the wrong decision is made. Furthermore, it makes a general analysis on the case drawing on the concept of bounded rationality, dual-process model, and skills acquisition theory. This article ends with some reflections from the case, to improve the consciousness and skills in decision-making for nursing interns.
From an aging person to an elegant senior: a humanistic approach to viewing older adults
Authors: Cheng Fung-Kei
Published: October 2020

The continuing growth in the number of adults aged 60-plus has raised global alertness of population restructuring. This demographic change, on the one hand, reduces productivity and increases public expenditure due to aging, resulting in prejudice, bias, misrepresentation, and discrimination against them. On the other hand, it develops a specific consumer market segment and extends the availability and accessibility of the elderly through employment, volunteering, or grandparenting. This study argues against the stigmatization of this age group from a functional perspective that damages social cohesion. It advocates a humanistic view toward seniors to eradicate marginalization and promotes the manageability of the senior population. With the aid of advanced technology and health equity, senior adults can retain everyday competence for self-care with dignity, as well as gracefully attain physical and psychological health, autonomy, and well-being in their later life. All these considerations give medical and nursing professionals insight into how to take care of the elderly.
Immigrants and tuberculosis in Europe – are we prepared for outbreak?
Authors: Koper Dorota , Pajączek Małgorzata , Kryczka Tomasz
Published: October 2020

Introduction. International travel and immigration have led to a rise in the incidence of tuberculosis in European countries, mainly due to migration from Africa and the Middle East.

Aim. In this article we point to an additional migration path - from Ukraine - and the threat of tuberculosis associated with this migration and we discuss our preparation for an increase in the incidence of this disease.

Discussion. It is estimated that about 1.5-2.5 million Ukrainians work or live in Poland or the EU. This results from the implementation of some EU directives and Polish law regulations, which simplified an access of the Ukrainian citizens to the European labor market. Importantly, Ukraine is one of the 18 high-priority countries to fight tuberculosis in the WHO European Region and among the top 20 highest drug-resistant tuberculosis burden countries in the world. More importantly, there is no unitary tuberculosis screening program for migrants in the EU member states. For this reason, we have no reliable data on tuberculosis burden in any nationality group of immigrants in Europe, including Ukrainians.

Conclusions. Nurses have always dealt with infectious diseases, they have always been and will be the last line of defense against the epidemic. Any epidemic, including tuberculosis. Perhaps, in the absence of an integrated tuberculosis policy in Europe, our only future are the experience, skills and dedication of nurses.

Authors: Rostiyanti Susy Fatena , Hansen Seng , Siregar Pratama H , Jodie Zevinska
Published: October 2020

The practice of providing safe temporary facilities for pedestrians during the execution of infrastructure projects is still challenging due to project complexity and the management of existing traffic flow. The challenge of ensuring pedestrian safety also becomes a concern in Jakarta, Indonesia, which currently has many ongoing infrastructure projects. The execution of these projects along existing main roads demands contractors to close some road lanes including pedestrian accesses. The circumstance highlights the importance of investigating the current practice in providing safe temporary pedestrian access. This study aims to investigate the safety and comfort measure of pedestrian access adjacent to the construction site. Nonconformities to safety findings from the field later are used as a basis for expert interviews in order to acquire recommendations. This research took a case study of the Light Rail Transit (LRT) project with a section length of 3.6 km. Observations took place every 100 meters and all nonconformities to safety data were recorded. Findings showed that among the potential nonconformities to safety, only six of those factors occurred frequently which later became the basis of questionnaire development for semi-structured expert interviews. Three experts from different backgrounds were chosen. Content analysis was used to analyze the data. Field observation result shows that among the six factors of nonconformity to safety, the unavailability of the separator system between the pedestrian access and road lane becomes the most occurred factor. The research demonstrates that in order to provide safety for pedestrians, access should be prepared with a minimum width of 90-100 cm, durable and stable surface, as well as a barrier that ensures safety against traffic and construction work. This study recommends the practical considerations for pedestrian safety as well as policies in terms of contractor’s organization and government in a broader perspective.
Determinants of executive compensation in South African state-owned enterprises
Authors: Maloa Frans , Bussin Mark
Published: October 2020

This research explores the determinants of executive compensation in South African state-owned enterprises (SOEs). A quantitative research approach wasfollowed and secondary data analysis was carried out. The target population consisted of 222 executives in 21 SOEs. This research has shown that the size of the organisation, type of industry and job function can be considered significant and positive determinants of executive compensation in South African SOEs. The findings of the present research also show that demographic characteristics are not significant determinants of executive compensation and should therefore not be taken into consideration when determining executive compensation in South African SOEs.

Objetivo: Analisar a prevalência de pacientes com Diabetes Mellitus tipo 2 e hipovitaminose e compreender os impactos clínicos dessa correlação. Métodos: Foi acessado o DeCS para delimitar e selecionar os seguintes descritores: metformin, vitamin B12 e diabetes mellitus. Nas bases de dados PubMed, LILACS e SciELO, com auxílio de filtros de buscas, foram selecionados 20 artigos publicados nos últimos 10 anos. Resultados: O Diabetes Mellitus tipo 2 tem como primeira escolha no tratamento a metformina, que ajuda no controle glicêmico, auxilia na perda ponderal, reduz os riscos cardiovasculares e a mortalidade. Em contrapartida, existem evidências significativas da associação do uso de metformina à deficiência de vitamina B12. Esta hipovitaminose de cobalamina resulta da interferência na ação da membrana dependente de cálcio responsável pela absorção do fator intrínseco da vitamina B12 no íleo terminal, resultando em neuropatias e anemias megaloblásticas. Portanto, diante deste quadro, é importante realizar o controle vitamínico dos pacientes para a reposição assim que necessária. Considerações finais: Os estudos selecionados apresentaram uma alta prevalência de deficiência ou possível hipovitaminose em usuários de metformina. Por fim, é necessária a realização de novos estudos sobre os impactos clínicos dessa hipovitaminose para elucidar a necessidade da suplementação.

Published: October 2020

Effective treatment or vaccine is not yet available for combating SARS coronavirus 2 (SARSCoV-2) that caused the COVID-19 pandemic. Recent studies showed that two drugs, Camostat and Nafamostat, might be repurposed to treat COVID-19 by inhibiting human TMPRSS2 required for proteolytic activation of viral spike (S) glycoprotein. However, their molecular mechanisms of pharmacological action remain unclear. Here, we perform molecular dynamics simulations to investigate their native binding sites on TMPRSS2. We revealed that both drugs could spontaneously and stably bind to the TMPRSS2 catalytic center, and thereby inhibit its proteolytic processing of the S protein. Also, we found that Nafamostat is more specific than Camostat for binding to the catalytic center, consistent with reported observation that Nafamostat blocks the SARS-CoV-2 infection at a lower concentration. Thus, this study provides mechanistic insights into the Camostat and Nafamostat inhibition of the SARS-CoV-2 infection, and offers useful information for COVID-19 drug development.

Published: October 2020

Reversing the polarity in molecules is a versatile tool for expanding the boundaries of structural space. Despite a manifold of different umpolung methods available today, overcoming the inherent reactivity still remains a constant challenge in organic chemistry. The oxidative α-functionalization of ketones by external nucleophiles constitute such an example. Herein, we present a hypervalent F-iodane mediated umpolung of pyridyl ketones triggered by Lewis base Lewis acid non-covalent interactions. A wide variety of external nucleophiles are introduced with high regioselectivity applying this substratedirecting concept.
Dynamics of Lithium Insertion in Electrochromic Titanium Dioxide Nanocrystal Ensembles

Published: October 2020

Nanocrystalline anatase TiO2 is a robust model anode for Li-insertion in batteries. The influence of nanocrystal size on the equilibrium potential and kinetics of Li-insertion is investigated with in operando spectroelectrochemistry of thin film electrodes. Distinct visible and infrared responses correlate with Li-insertion and electron accumulation, respectively, and these optical signals are used to deconvolute Li-insertion from other electrochemical responses, such as double-layer capacitance and electrolyte leakage. Electrochemical titration and phase-field simulations reveal that a difference in surface energies between anatase and lithiated phases of TiO2 systematically tunes Li-insertion potentials with particle size. However, particle size does not affect the kinetics of Li-insertion in ensemble electrodes. Rather, Li-insertion rates depend on applied overpotential, electrolyte concentration, and initial state-of-charge. We conclude that Li diffusivity and phase propagation are not rate-limiting during Li-insertion in TiO2 nanocrystals. Both of these processes occur rapidly once the transformation between the low-Li anatase and high-Li orthorhombic phases begins in a particle. Instead, discontinuous kinetics of Li accumulation in TiO2 particles prior to the phase transformations limits (dis)charging rates. We demonstrate a practical means to deconvolute non-equilibrium charging behavior in nanocrystalline electrodes through a combination of colloidal synthesis, phase field simulations and spectroelectrochemistry.
Characterizing the Turbostratic Disorder in COF-5 with NMR Crystallography
Authors: Pope Giovanna , Vazquez Demetrius , Uribe-Romo Fernando , Harper James K.
Published: October 2020

Since its initial synthesis in 2005, COF-5 has been known to have intrinsic disorder in the placement of the 2D layers relative to one another (i.e. turbostratic disorder). Prior studies of have demonstrated that the eclipsed layering found in the space group originally assigned to COF-5 (P6/mmm) is inconsistent with energy considerations. Herein it is demonstrated that eclipsed layers are also inconsistent with 13C solid-state NMR data. Crystal structure predictions are made in five alternative space groups and good agreement is obtained in P21/m, Cmcm, and C2/m. We posit that all three space groups are present within the stacked 2D layers and show that this conclusion is consistent with evidence from 13C solid-state NMR linewidths and chemical shifts, powder x-ray diffraction data and energy considerations. An alternative explanation involving a mixture of multiple pure phases is rejected because the observed NMR spectra don’t exhibit the characteristic features of such mixed phase materials.
Osmolytes and Macromolecular Crowders Diversely Affect the Aggregation of the Cancerrelated L106R Mutant of the Axin RGS Domain
Authors: Garfagnini Tommaso , Harries Daniel , Friedler Assaf
Published: October 2020

Protein aggregation is involved in a variety of diseases, including neurodegenerative diseases and cancer. The cellular environment is crowded by a plethora of cosolutes comprising small molecules and biomacromolecules at high concentrations, which may influence the aggregation of proteins in vivo. To account for the effect of cosolutes on cancer-related protein aggregation, we studied their effect on the aggregation of the cancer-related L106R mutant of the Axin protein. Axin is a key player in the Wnt signaling pathway, and the L106R mutation in its RGS domain results in a native molten globule that tends to form native-like aggregates. This results in uncontrolled activation of the Wnt signaling pathway, leading to cancer. We monitored the aggregation process of Axin RGS L106Rin vitro in the presence of a wide ensemble of cosolutes including polyols, amino acids, betaine and polyethylene glycol (PEG) crowders. Except myo-inositol, all polyols decreased RGS L106R aggregation, with carbohydrates exerting the strongest inhibition. Conversely, betaine and PEGs enhanced aggregation. These results are consistent with the reported effects of osmolytes and crowders on the stability of molten globular proteins and with both amorphous and amyloid aggregation mechanisms. We suggest a model of Axin L106R aggregation in vivo, whereby molecularly small osmolytes keep the protein as a free solublemolecule but the increased crowding of the bound state by macromolecules induces its aggregation at the nano-scale. Our study sheds light on the potential contribution of cosolutes to the onset of cancer as a protein misfolding disease, and on the relevance of aggregation in the molecular aetiology of cancer.
An Affordable Option to Au Single Crystals Through Cathodic Corrosion of a Wire: Fabrication, Electrochemical Behavior, and Applications in Electrocatalysis and Spectroscopy
Authors: Elnagar Mohamed , Hermann Johannes M. , Jacob Timo , Kibler Ludwig A.
Published: October 2020

Faceting and nanostructuring of polycrystalline gold electrodes by cathodic corrosion in concentrated potassium hydroxide electrolytes has been systematically studied at different electrode potentials. Current-potential curves for the restructured Au electrodes in 0.1 M H2SO4 show characteristic features of Au(111) facets in the double-layer and oxidation region. Thus, the modified Au electrodes adopt properties typically known for well-defined single crystal surfaces. Besides the preferential surface faceting, the electrochemically active surface area (EASA) is enhanced as a function of potential, concentration and time. Scanning electron micrographs show the formation of well-defined triangular pits and nanostructures with a specific orientation confirming the formation of (111)-facets. In this way, the behavior of single crystals is accompanied with the properties of nanoparticles which are of utmost interest in electrocatalysis and surface enhanced Raman spectroscopy (SERS). The electrocatalytic activity of the newly formed “Au(111)” surface from an Au wire has been tested towards the hydrogen evolution reaction (HER) and for the formic acid oxidation reaction (FAOR). The study of electrocatalytic reactions at these nanostructured electrodes allows to identify active centers, which are absent for extended single crystal surfaces. Adsorbed pyridine on the nanostructured Au electrodes directly shows SERS activity, while untreated polycrystalline Au is SERS-inactive. The use of cathodic corrosion of simple wires is a paradigm of SERS-applications in electrochemistry with clean Au electrodes that provide properties of Au(111) single crystals.

Stroke is basically a medical condition where there is low blood flow to the brain and thus results in cell death. It remains the second most common cause of death. Stroke patients also have different comorbidities on an average where they are prescribed with 6-10 medicines. This increase the chances for drug-related problems (DRPs) and adverse drug events (ADEs) or adverse drug reactions (ADRs) and the interventions found during the follow up of stroke patients. Several studies finding of interventions in stroke patients and reconciliation are ways to reduce ADRs and improve medication use safety. Interventions and medical reconciliation (MR) address a wide array of potential medication-related issues, which is carefully planned that may be done by pharmacist or doctor or professional (or) physician. Here the aim was to access the impact of interventions which includes medications reconciliation and counselling of stroke patients and also identification and categorization of DRPs. Polypharmacy causing DRPs was statistically significant in all the regions inappropriate drug selection (2.85%), and dose selection (2.85%) was the primary cause of DRPs 85% partially solved. Epidemiologically of all the three regions (GNT, VIJ, RJY) in the total study population. Males are more affected than females. Majority of comorbidities like HTN(70.05%), and DM(47.01%)were in leading role causing stroke absorbed during interventions. Leaflet & patient counselling had prominent role in conducting medical reconciliation. Other health care professionals systematically find, differentiate & report interventions like (DRPs, ADRs, and causes).

Using particle swarm optimisation and the silhouette metric to estimate the number of clusters, select features, and perform clustering
Authors: Lensen Andrew , Xue Bing , Zhang Mengjie
Published: October 2020

© Springer International Publishing AG 2017. One of the most difficult problems in clustering, the task of grouping similar instances in a dataset, is automatically determining the number of clusters that should be created. When a dataset has a large number of attributes (features), this task becomes even more difficult due to the relationship between the number of features and the number of clusters produced. One method of addressing this is feature selection, the process of selecting a subset of features to be used. Evolutionary computation techniques have been used very effectively for solving clustering problems, but have seen little use for simultaneously performing the three tasks of clustering, feature selection, and determining the number of clusters. Furthermore, only a small number of existing methods exist, but they have a number of limitations that affect their performance and scalability. In this work, we introduce a number of novel techniques for improving the performance of these three tasks using particle swarm optimisation and statistical techniques. We conduct a series of experiments across a range of datasets with clustering problems of varying difficulty. The results show our proposed methods achieve significantly better clustering performance than existing methods, while only using a small number of features and automatically determining the number of clusters more accurately.
