Persistent Homology as Stopping-Criterion for Voronoi Interpolation
Authors: Melodia Luciano
Published: August 2020

In this study the Voronoi interpolation is used to interpolate a set of points drawn from a topological space with higher homology groups on its filtration. The technique is based on Voronoi tessellation, which induces a natural dual map to the Delaunay triangulation. Advantage is taken from this fact calculating the persistent homology on it after each iteration to capture the changing topology of the data. The boundary points are identified as critical. The Bottleneck and Wasserstein distance serve as a measure of quality between the original point set and the interpolation. If the norm of two distances exceeds a heuristically determined threshold, the algorithm terminates. We give the theoretical basis for this approach and justify its validity with numerical experiments.

Authors: Yang Kaiqiao , Du Yue , WANG YUAN , man tang , Liu Qiuyun
Published: August 2020

Tangshan earthquake in China occurred with a periodicity of 297 years with focal depth of 11 km. An average of 0.10147 meter of earth crust is uplifted every day. The 9.0 magnitude earthquake was said to occur once every other 1100 years off the northeastern pacific coast of Japan with a focal depth of 20 km. An average of 0.04981 meter of earth’s crust is uplifted daily. These results can be viewed as slope coefficient or potential energy coefficient. Other coefficient such as latitude needs to be incorporated for theoretical calculations.

The study aimed to create a machine learning method for differentiating diagnostically valued tumorous tissue from diagnostically “non-valued” non-tumorous tissues in the human brain, using cross-polarization optical coherence tomography (CP OCT) in order to provide guidance for stereotactic biopsies. A method of feature extraction from OCT data in two orthogonal polarization channels has been proposed and a classification algorithm for the resulting feature vectors has been created. If used for stereotactic biopsy guidance, the proposed approach could decrease the number of excised diagnostically non-valued samples and minimize the invasiveness of the procedure and the risk of excessive bleeding.

Behavioral immune tradeoffs: Interpersonal value relaxes social pathogen avoidance
Authors: Tybur Joshua M. , Lieberman Debra , Fan Lei , Kupfer Tom , de Vries Reinout E.
Published: August 2020

Behavioral immune system research has illuminated how people detect and avoid signs of infectious disease. But how do we regulate exposure to pathogens that produce no symptoms in their hosts? This manuscript tests the proposition that estimates of interpersonal value are used for this task. Three studies (N = 1694), each conducted using U.S. samples, are consistent with this proposition: people are less averse to engaging in infection-risky acts not only with friends relative to foes, but also with honest and agreeable strangers relative to dishonest and disagreeable ones. Further, a continuous measure of how much a person values a target covaries with comfort with infection-risky acts with that target, even within relationship categories. Findings indicate that social prophylactic motivations arise not only from cues to infectiousness, but also interpersonal value. Consequently, pathogen transmission within social networks might be exacerbated by relaxed contamination aversions with highly valued social partners.
Developmental trajectories in the understanding of everyday uncertainty terms
Authors: Meder Björn , Mayrhofer Ralf , Ruggeri Azzurra
Published: August 2020

Dealing with uncertainty and different degrees of frequency and probability is critical in many everyday activities. However, relevant information does not always come in the form of numerical estimates or direct experiences, but is instead obtained through qualitative, rather vague verbal terms (e.g., “the virus often causes coughing” or “the train is likely to be delayed”). Investigating how people interpret and utilize different natural language expressions of frequency and probability is therefore crucial to understand reasoning and behavior in real-world situations. While there is considerable work exploring how adults understand everyday uncertainty phrases, very little is known about how children interpret them and how their understanding develops with age. We take a developmental and computational perspective to address this issue and examine how 4- to 14-year-old children and adults interpret different terms. Each participant provided numerical estimates for 14 expressions, comprising both frequency and probability phrases. In total we obtained 2,856 quantitative judgments, including 2,240 judgments from children. Our findings demonstrate that adult-like intuitions about the interpretation of everyday uncertainty terms emerge surprisingly early in development, with the quantitative estimates of children converging to those of adults from around 9 years on. We also demonstrate how the vagueness of verbal terms can be represented through probability distributions, which provides additional leverage for tracking developmental shifts through cognitive modeling techniques. Taken together, our findings provide key insights into the developmental trajectories underlying the understanding of everyday uncertainty terms, and open up novel methodological pathways to formally model the vagueness of probability and frequency phrases, which are abundant in our everyday life and activities.
Making it abstract, making it contestable: Politicization at the intersection of political and cognitive science
Authors: Mazzuca Claudia , Santarelli Matteo
Published: August 2020

The notion of politicization has been often assimilated to that of partisanship, especially in political and social sciences. However, these accounts underestimate more fine-grained, and yet pivotal, aspects at stake in processes of politicization. In addition, they overlook cognitive mechanisms underlying politicizing practices. Here, we propose an integrated approach to politicization relying on recent insights from both social and political sciences, as well as cognitive science. We outline two key facets of politicization, that we call partial indetermination and contestability, and we show how these can be accounted for by appealing to recent literature in cognitive science concerned with abstract conceptual knowledge. We suggest that politicizing a concept often implies making its more abstract components more salient, hence legitimating its contestable character. Finally, we provide preliminary suggestions to test our proposal, using the concept of gender as case study.

Published: August 2020

After its relative lenient, “intelligent lockdown” approach to the COVID-19 coronavirus, the Netherlands has continued its singular trajectory in combating the pandemic. The month of July introduced further relaxations to prior mitigation measures, but also saw a resurgence of infections. This working paper examines how these developments are reflected in Dutch citizens’ compliance with safe-distance measures during this period. Building on our previous surveys during the months of May and June, we report the findings of two additional survey waves collected in early (7-10) and late (21-23) July among nationally representative samples (N = 1064 and N = 1023, respectively). The results show that the decline in compliance that was observed from May to June seems to have halted. At the same time, important predictors of compliance – such as citizens’ capacity to comply, perceptions of the threat of the virus, and support for mitigation measures – have ceased to decrease, or are increasing. Taken together, these findings suggest that Dutch citizens’ compliance with mitigation measures may be on the rise again. However, our findings also suggest that social norms for compliance continue to be eroding, which may continue to dampen citizens’ tendency to comply.
Deep Learning Schätzung absorbierter Strahlungsdosis für die nuklearmedizinische Diagnostik
Authors: Melodia Luciano
Published: August 2020

The distribution of energy dose from Lu177 radiotherapy can be estimated by convolving an image of a time-integrated activity distribution with a dose voxel kernel (DVK) consisting of different types of tissues. This fast and inacurate approximation is inappropriate for personalized dosimetry as it neglects tissue heterogenity. The latter can be calculated using different imaging techniques such as CT and SPECT combined with a time consuming monte-carlo simulation. The aim of this study is, for the first time, an estimation of DVKs from CT-derived density kernels (DK) via deep learning in convolutional neural networks (CNNs). The proposed CNN achieved, on the test set, a mean intersection over union (IOU) of =0.86 after 308 epochs and a corresponding mean squared error (MSE) =1.24⋅10−4. This generalization ability shows that the trained CNN can indeed learn the difficult transfer function from DK to DVK. Future work will evaluate DVKs estimated by CNNs with full monte-carlo simulations of a whole body CT to predict patient specific voxel dose maps.

Indocyanine green videoangiography for recipient vessel stratification in superficial temporal artery–middle cerebral artery bypass surgery
Authors: Goldberg Johannes , Vajkoczy Peter , Hecht Nils
Published: August 2020

OBJECTIVE

In superficial temporal artery–middle cerebral artery (STA-MCA) bypass surgery, recipient vessel properties are likely one of the main reasons for bypass failure. In daily practice, most surgeons select the recipient with the largest diameter. However, selection of the ideal recipient remains debatable because there are no objective selection criteria if multiple potential recipients exist. Here, the authors assessed the benefit of using indocyanine green videoangiography (ICG-VA) to optimize recipient vessel selection in patients undergoing STA-MCA bypass surgery for hemodynamic compromise.

METHODS

All patients who had undergone STA-MCA bypass procedures with pre- and postanastomosis ICG-VA between 2010 and 2019 were eligible for inclusion in this study. The primary bypass surgeon was blinded to the preanastomosis ICG-VA. Preanastomosis white-light and ICG-VA images were compared to determine the identifiability of potential recipient vessels and pathological flow patterns. After completion of the anastomosis, a second (postanastomosis) ICG-VA image was used to analyze the flow increase within the chosen recipient based on the vessel diameter, initial recipient blood flow, initial sequence of appearance on ICG-VA, initial blood flow direction within the recipient, and orientation of the bypass graft. ICG-VA, FLOW 800, and intraoperative white-light images, as well as demographic, clinical, and radiographic patient data, were retrospectively analyzed by a clinician who was not directly involved in the patients’ care.

RESULTS

Sixty patients underwent 65 STA-MCA bypass procedures with pre- and postanastomosis ICG-VA. The ICG-VA permitted identification of a significantly higher number of potential recipient vessels (median 4, range 1–9) than the white-light images (median 2, range 1–5; p < 0.001), with detection of pathological flow patterns in 20% of all procedures. No association was found between the diameter and blood flow within potential recipients (Spearman r = 0.07, p = 0.69). After bypass grafting, the highest flow increase was noted in recipients with an initially low flow (p < 0.01), a late appearance (p < 0.01), and an initially retrograde flow direction (p = 0.02). Interestingly, flow increase was not significantly influenced by the recipient diameter (p = 0.09) or graft orientation (p = 0.44).

CONCLUSIONS

ICG-VA facilitates identification of potential recipient vessels and detection of pathological flow patterns. Recipients with an initially low flow, a late appearance, and a retrograde flow seem to bear the highest potential for flow increase, possibly due to a higher hemodynamic need for revascularization.

Published: August 2020

OBJECTIVE

The incidence of postoperative shoulder imbalance following posterior spinal fusion (PSF) is still high in Lenke 1 curves despite following current treatment recommendations for upper instrumented vertebra (UIV) selection. The objective of this retrospective study was to identify differences in preoperative shoulder balance and to report the surgical outcome of two subtypes of Lenke 1 curves (flexible vs stiff) in patients with adolescent idiopathic scoliosis (AIS).

METHODS

The authors grouped patients’ curves as Lenke 1–ve (flexible) when their preoperative proximal thoracic side bending (PTSB) Cobb angle was < 15° and as Lenke 1+ve (stiff) when the PTSB Cobb angle was 15°–24.9°. The authors hypothesized that these two subtypes had distinct preoperative and postoperative shoulder and neck balance following PSF using pedicle screw constructs.

RESULTS

Fifty patients had Lenke 1 (flexible) curves and 61 had Lenke 1 (stiff) curves. The mean preoperative T1 tilt for patients with Lenke 1 (flexible) was −4.9° ± 5.3°, and for those with Lenke 1 (stiff) curves it was −1.0° ± 5.3° (p < 0.001). Mean cervical axis (CA) was −0.1° ± 3.2° for Lenke 1 (flexible) curves and 2.3° ± 3.5° for Lenke 1 (stiff) curves (p < 0.001). Preoperative radiographic shoulder height (RSH) and clavicle angle (Cla-A) were similar between the two curve subtypes. Following surgery, there were significant differences between the subtypes in terms of T1 tilt (p < 0.001), RSH (p = 0.014), and Cla-A (p = 0.031). Interestingly, 41.0% of patients with a Lenke 1 (stiff) curve had +ve T1 tilt compared to 2.0% in Lenke 1 (flexible) group. Moreover, 26.2% of patients with the Lenke 1 (stiff) curve had +ve RSH compared to 12.0% of those with Lenke 1 (flexible) curves. And, 24.6% of patients with Lenke 1 (stiff) had +ve Cla-A compared to 10.0% of those with Lenke 1 (flexible) curves.

CONCLUSIONS

Lenke 1 (flexible) and Lenke 1 (stiff) curves had distinct preoperative T1 tilt and CA measurements. Following PSF, the authors noted +ve T1 tilt in 41% of patients with Lenke 1 (stiff) curves versus 2.0% in those with Lenke 1 (flexible) curves. The authors also noted a significant difference in postoperative RSH and Cla-A measurements.

Published: August 2020

Background. Coronary artery disease (CAD) is caused by narrowing of the coronary arteries. In the event of acute myocardial infarction (AMI), there will be an increase in heart markers. Several studies have examined the relationship between Platelet Distribution Width (PDW) and AMI, but there is no specific correlation with troponin as the most sensitive and specific cardiac biomarker for AMI. This study aims to see the correlation PDW values with troponin I in patients with AMI. Method. This study was a cross-sectional method to determine the correlation of PDW variable values ​​with troponin I in patients with AMI. In this study, the sample consisted of 64 people. Results. There is a moderate correlation between PDW and troponin I (r2= 0.72, p <0.001). There is a strong correlation with positive direction between PDW and Troponin I in patients with AMI based on the onset of chest pain (<6 hours and > 6 hours : r2 = 0.647 p <0.001and r2 = 0.756, p <0.001). Conclusion. Platelet Distribution Width (PDW) is strongly correlated with Troponin I in patients with AMI, and based on chest pain onset also has a significantly positive correlation.

Published: August 2020

Background Coronary Heart Disease (CHD) is one of the leading causes of death in developed and developing countries.  Syzygium polyanthum leaf (daun salam) are reported to have anti-inflammatory, antioxidant, antidiabetic, antimicrobial, antihypertensive, antitumor, antidiarrheal, acetylcholinesterase inhibition, and lipase inhibitory activity. The purpose of this study was to prove the effect of bay leaf extract (Syzygium polyanthum) on serum interleukin (IL)-10 levels in the heart of Wistar Strain Mice Model of Acute Coronary Syndrome (ACS). Methods This is an experimental study to compare the IL-10 level in 32 ACS mice which were divided into 8 groups. Serum IL-10 values were collected and analyzed according to the corresponding group with and without bay leaf extract administration, on day 1,4,7, and 14. Result: There is an IL-10 value increasing with the duration of examination following the onset of ACS induction. The highest average IL-10 value was found on the 14th day, in the two groups. On the same day, it was seen that the treatment group had a higher IL-10 value compared to the control group (p<0.001). The result showed that the concentration of IL-10 was significantly greater among the treatment group, which  reveal the potential benefit of bay leaf extract in patients with ACS. Conclusion: There was found a significant difference of serum IL-10 between Wistar Strain Mice Model of ACS that was given S. polyanthum leaf extracts.

Una nueva perspectiva sobre la densidad actual de conducción
Authors: Lucena Lucas Ruas de
Published: August 2020

Este artículo analiza propuestas alternativas y complementarias a las leyes de J.C.Maxwell del electromagnetismo clásico, basadas en ciertas hipótesis, ejemplos hipotéticos y cálculos, con resultados que pueden inferir nuevas interpretaciones sobre la densidad actual de conducción del fenómeno físico. Estas nuevas interpretaciones aportan un nuevo entendimiento a la dinámica de la Ley de Gauss y, siendo ciertas, hacen que la Ley Ampère-Maxwell sea totalmente simétrica a la ley Faraday-Lenz-Maxwell, sin ninguna incoherencia matemática o física. Estos entendimientos inevitablemente traen implicaciones y puntos de vista complementarios a la teoría clásica del electromagnetismo.

ABSTRACT

 

Background

Mayer-Rokitansky-Kuster-Hauser Syndrome (MRKH) is caused by an embryological growth disorder of the mullerian duct. Laparoscopic Vecchietti and Davydov are laparoscopic surgery techniques that are often used for neovaginal surgery

 

Objective

This paper aims to compare the success rate of neovagina with the Vecchietti laparoscopic method and Davydov's laparoscopic method in patients with Mayer-Rokitansky-Kuster-Hauser Syndrome (MRKH)

 

Methods: A systematic data search was performed on a medical database (PUBMED, MEDLINE, Cochrane Database, Google Scholar). Inclusion criteria: (1) randomized randomized study of the Vecchietti Laparoscopic Method with Davydov’s Laparoscopy, (2) all inclusive papers can be accessed completely, and (3) the data obtained can be accurately analyzed

 

Data acquisition and analysis: We searched for a random blind study (RCT) with the following keywords: (1) Vecchietti Laparoscopy [title] AND (2) Davydov’s Laparoscopy [title] AND Mayer-Rokitansky-Kuster-Hauser syndrome [title]

 

Results: Three RCTs comparing neovaginal success with the Vecchietti laparoscopic method and Davydov's laparoscopic method a total of 122 patients were analyzed. Average vaginal length (mean difference [MD] -0.70, and 95% [CI] -0.99 to -0.41 (P <0.00001), Average number of Female Sexual Function Index scores (mean difference [MD] -1.34, and 95% [CI] -1.71 through -0.96. (P <0.00001)

Olof Palme: One Life, Many Readings
Authors: Quirico Monica
Published: August 2020

The analysis of Olof Palme’s politics and of his legacy in Swedish Social Democracy has been somewhat “frozen” due to two uncommon circumstances. Firstly, there has been his violent death, which makes it uneasy for commentators to express any detached judgement. Secondly, there has been a kind of sin of omission; that is to say, in looking at his figure, right-wing as well as left-wing politicians and intellectuals have recalled the man – whose biography is undoubtedly a success story – rather than discussing his contribution to national history and to the Social Democratic movement.
Aðskilnaður ríkis og kirkju. Almenn umræða á „stuttri tuttugustu öld“. Fyrri grein - Með aðskilnaði
Authors: Hugason Hjalti
Published: August 2020

In this article and another which follows the author analyses the discourse about the separation of the state and the national church in Iceland over the period 1915–1995 — called “the short 20th century”. In this first article it will be dealt with the arguments for separation. In the second one views against separation will be discussed.

Various ecclesiastical, theological or religious arguments were presented for separation. First it was pointed out that the liberal theology had made a schism within the national church which according to the constitution of Iceland should be evangelical-Lutheran. Therefore, it would be best to separate the church from the state as soon as possible so that the liberal ones and the conservatives could go their own ways in the future. Later it was stated that the separation between the state and the national church increased the freedom of church in fulfilling its vocation. It was also argued for separation from the ecumenical point of view and stated that the religious communities in the country should stand on equal footing in spite of various size.

Many advocated for separation on the basis of human rights views. Some of them stated that the national church system effectively prevented the constitutional religious freedom of the people. It was also pointed out that the national church enjoyed a multitude of direct and indirect economical support from the state. In this way, all Icelanders indirectly participated in the cost of churchwork regardless of their church membership and religious beliefs.

Finally, some recommended separation of financial reasons. They pointed out that the state invested large sums in the church, which, however, had few formal roles in the society.

Background/Aims: Data on treatment efficacy and safety of glecaprevir/pibrentasvir (GLE/PIB) for chronic hepatitis C virus (HCV) infection in Asian patients with severe renal impairment are limited. This study aimed to study the treatment and side effects of GLE/PIB in these patients infected with non-1 genotype (GT) HCV.Methods: We prospectively recruited patients with Child’s A cirrhosis and eGFR <30 mL/min/1.73 m2 in Hong Kong and Taiwan during 2017–2018 to receive GLE/PIB treatment.Results: Twenty-one patients (GT2, n=7; GT3, n=6; and GT6, n=8) received GLE/PIB for 11.2±1.8 weeks. All except one were treatment-naïve. GLE/PIB was initiated in 16 patients while on dialysis (seven on peritoneal dialysis [PD] and nine on hemodialysis) and in five patients before dialysis. One patient died of PD-related peritonitis during treatment and two were lost to follow up. The SVR12 rate in the remaining 18 patients was 100%. All patients achieved undetectable levels at 4-, 12-, 24- and 48-week after treatment. Patients with deranged alanine aminotransferase showed normalization after 4 weeks and the response was sustained for 48 weeks. No significant adverse event was observed.Conclusions: GLE/PIB treatment was associated with high efficacy and tolerability in HCV-infected patients with severe renal impairment.

Diabetes mellitus is associated with increased inflammatory response, which may contribute to atherosclerosis progression. Experimental results demonstrated anti-inflammatory activity of glitazones; their effect on leukocyte adhesion molecules has not been studied to date. We therefore studied the effect of rosiglitazone treatment on leukocyte surface expression of adhesion molecules in patients with type 2 diabetes mellitus and compared our results with findings in healthy subjects. 33 subjects with type 2 diabetes and 32 healthy controls were included; patients were examined at baseline and after 5 months of rosiglitazone treatment (4 mg/d). Leukocyte expression of adhesion molecules LFA-1, CD18 and ICAM-1 was quantified using flow cytometry; in addition, CD14 (lipopolysaccharide receptor) expression was analyzed as a marker of nonspecific immunity. The expression of examined molecules at baseline was higher in patients compared to controls. Despite only mild decrease in blood glucose, rosiglitazone treatment induced substantial decrease of CD18 and CD14 expression and borderline decrease of LFA-1 and ICAM-1 expression (on monocytes only). We thus observed improvement in the expression of leukocyte inflammatory markers after rosiglitazone treatment. This effect is supposed to be mediated by direct effect of rosiglitazone on PPAR-γ receptors on leukocytes.
Editor’s Pick: Regulatory and Ethical Issues in the New Era of Radiomics and Radiogenomics
Authors: Pesapane Filippo
Published: August 2020

Radiomics is a science that investigates a large number of features from medical images using data-characterisation algorithms, with the aim to analyse disease characteristics that are indistinguishable to the naked eye. Radiogenomics attempts to establish and examine the relationship between tumour genomic characteristics and their radiologic appearance. Although there is certainly a lot to learn from these relationships, one could ask the question: what is the practical significance of radiogenomic discoveries? This increasing interest in such applications inevitably raises numerous legal and ethical questions. In an environment such as the technology field, which changes quickly and unpredictably, regulations need to be timely in order to be relevant.  In this paper, issues that must be solved to make the future applications of this innovative technology safe and useful are analysed.

Experiment on obtaining an algologically pure culture of Tetraselmis viridis in non-sterile conditions
Authors: Gorbunova Svetlana Yu. , Trenkenshu Rudolf P.
Published: August 2020

The possibility of obtaining an algologically pure culture of Tetraselmis viridis, grown on the Black Sea water in non-sterile conditions, was shown experimentally. Our experiments showed that at low initial population density of the culture after 1–3 days, there was an infection of the culture with blue-green species of microalgae (Oscillatoria sp.). Thrice repeated mechanical removal of blue-green microalgae cells by filtering the infected culture allowed obtaining an algologically pure culture of T. viridis. Under similar conditions of T. viridis cultivation, but with the initial addition of NaCl (15 g/l) to the nutrient medium aimed at increasing salinity to the Mediterranean level, there was no contamination of the culture.
