La trombocitosis es un marcador de supervivencia reducida en pacientes con carcinoma de células renales.
Authors: Cadena Castro Luis Eduardo , Cadena Vizuete Jorge Eduardo
Published: September 2022

Introduction: Thrombocytosis occurs as an inflammatory bone marrow response in the presence of chronic diseases, generally infectious. The association of thrombocytosis and its prognostic impact on survival in patients with renal cell carcinoma (RCC) has not been definitively established. This study aimed to determine survival rates in two reference centers in Quito-Ecuador for treating patients with RCC.
Methods: The present longitudinal study was conducted at the "Carlos Andrade Marín" Specialty Hospital and the General Specialty Hospital Number 1, in Quito-Ecuador, from January 2005 to December 2016. Patients with CRC at one year of age were included. Survival since nephrectomy was determined. Mortality, age, staging, and survival were determined. Two groups with the presence or absence of thrombocytosis were analyzed. The sample was probabilistic. Survival analysis is performed using the Kaplan-Meier method, and a COX regression is performed on the associated variables.
Results: 183 patients, 62.2 ± 12.8 years old, were included. There were 132 cases (72.1%) of localized CRC, 35 cases (19.1%) of advanced stage, and 16 cases (8.7%) of the metastatic stage. The mean number of platelets was 300020 ±102300 u/ul. Fifty patients (27.3%) presented thrombocytosis. Overall survival of the group with thrombocytosis was 50.4 (38.2-62.6) months versus 68.1 (60.8-75.3) months in the group without thrombocytosis, P<0.005.

Authors: Rojas Canchala Maricela Suleidy , Troya Ronquillo Paola Cristina , Almagro Guerrero Patricio , Rivera Buse José
Published: September 2022

Introduction: The microvascular similarities of the retina and the kidney cause the manifestations of diabetic microangiopathy to occur in both systems. Few epidemiological data exist on this group of patients with stage 5 chronic kidney disease (CKD), so the objective of this study was to determine the prevalence of proliferative and non-proliferative diabetic retinopathy (PDR) in patients undergoing hemodialysis.
Methods: In this cross-sectional study, 205 type 2 diabetic patients with stage 5 CKD undergoing hemodialysis at the Hospital Eugenio Espejo from June 2013 to May 2014 were evaluated. Comorbidity was determined in all patients (n=205). Associated abilities, glycosylated hemoglobin, time of evolution of DM2, and diagnosis of diabetic retinopathy were determined. In all eyes (n=410), visual acuity, degree of diabetic retinopathy, and complications of diabetic retinopathy were determined.
Results: Of 205 patients, 62.9% were women, 53.7% were aged between 70-79 years, the time of evolution of DM2 was more significant than 20 years in 65.9%, and 83.4% were treated with insulin. 92.2% had DR, 58% were cases of non-proliferative DR, and 34.2% had PDR.
Conclusions: There is a high prevalence of DR in this group of a non-symmetrical type. The severity of the involvement concerns kidney damage since more than half of the patients present RDNP while the kidney is in end-stage renal failure.
Variabilidad biológica intra y extra individual de calcio total, urea y creatinina en pacientes adultos con insuficiencia renal crónica prediálisis y postdiálisis.
Authors: Vernaza Guerra Cristina Paola , Pazmiño Martínez Lourdes Alicia
Published: September 2022

Introduction: The intra- and inter-individual variability of calcium, urea, and creatinine in hemodialysis patients depends on their nutritional status and the removal produced by the treatment. The objective of the present study was to determine the variability over a 10-month observation period in a group of patients in a hemodialysis program.
Methods: This longitudinal study was conducted with adult patients with stage 5-d chronic kidney disease from the Clinef-Norte dialysis center in Quito, Ecuador. The variables were age, sex, urea, creatinine, and total calcium before and after dialysis. The sample was probabilistic, consisting of 120 cases. The individual biological variation (CVI), the inter-individual biological variation (CVG), the change reference value, and the relative variation coefficient (CVR) were calculated.
Results: 165 cases, 60.5 ± 15.2 years old, were analyzed. The CVI of urea was 0.36%, and CVG of 0.87% pre-dialysis, 24.3%, and 28.94% post-dialysis. Creatinine CVI was 10.8%, CVG 24.23% pre-dialysis, post-dialysis CVI 12.9%, and CVG 36.36%. The CVI of Calcium was not calculable; the CVG was 7.31%.
Conclusions: The CVI of pre-dialysis urea indicated a regular protein intake, a finding with significant implications for patient care. The CVI of post-dialysis urea was variable and is related to differences in the prescription of the extracorporeal flow of hemodialysis, highlighting the need for personalized treatment. The CVI of serum creatinine has implications for constant loss of muscle mass in the study time, a practical consideration for patient management. Calcium GVC was associated with an increase in calcaemia in the first four months and a continuous fall after this period, probably associated with a decrease in the intake of calcium products after the 4th month of dialysis treatment, a finding that can guide dietary recommendations.
Determinación de Cistatina C como marcador de función renal en pacientes normoalbuminúricos con Diabetes Mellitus tipo 2.
Authors: Alcívar Vásquez Juan Manuel , Puig Gilbert Carlos Alberto , Wong Lama Jeany , Flor Rodríguez Miguel Angel
Published: September 2022

Introduction: Early identification of impaired renal function is crucial in diabetic patients. Clinically, serum cystatin C could be the most sensitive indicator of glomerular filtration rate. The present study's objective was to propose using cystatin C as a routine test to evaluate renal function in type 2 diabetic patients.
Methods: An observational cross-sectional study on 115 normoalbuminuric type two diabetic patients, establishing the glomerular filtration rate with cystatin C values and the Cockroft-Gault formula. Those with a glomerular filtration rate < 60 mL/min underwent 24-hour urine creatinine clearance. We compared the results with the statistical program SPSS 17, presenting the data in contingency tables with risk analysis and significance test of X2
Results: The glomerular filtration rate obtained with cystatin C had an average value of 99 ± 19.07 ml/min/1.73 square meters of body surface (SMS). The Cockroft-Gault value was 79.85 ± 23.63 ml/min/1.73 sms, reflecting a better correlation with creatinine clearance in 24-hour urine, which was 74.95 ± 37.41 ml/min/1.73 sms. Both parameters had no significant relationship when relating the values to the 24-hour urinary creatinine clearance (P = 0.14).
Conclusions: The glomerular filtration rate with cystatin C presents a significant dispersion in the correlation with the creatinine clearance in the urine for 24 hours; this fact, together with various factors that influence its variability, and the higher cost of its determination, make its use to assess renal function little justifiable.

Published: September 2022

Hospitals and the concept of a healthcare delivery system are practically synonymous. Surgical services, emergency and disaster services, and inpatient care are the three main services they offer. Outpatient clinics and facilities are also available at some hospitals, where patients can receive specialty consultations and surgical services. What challenges do hospital administrators face when attempting to balance the supply and demand for medical services while preserving service quality and maintaining low prices? In what ways and to what extent has OM literature contributed to the resolution of these issues? What are the current trends in practice? What additional opportunities and challenges do they present to OM students? This study is an attempt by the authors to answer the aforementioned questions. Although service capacity could be measured by the number of physical and human resources employed, we chose to focus on the three primary types of services provided by hospitals.
3 x Ukraine: Zur Politischen Soziologie eines Angriffskriegs
Authors: Schlichte Klaus
Published: September 2022

Im Unterschied zu allen anderen Kriegen der Gegenwart hat der Angriff Russlands auf die Ukraine zahlreiche moralische und politische Statements von Wissenschaftler*innen im Fach der Internationalen Beziehungen hervorgerufen. Realistische wie liberale Ansätze deduzieren dabei Erklärungen eher aus ihrem Theoriebestand, als sie aus dem Material zu entwickeln. Der Beitrag schlägt stattdessen eine kritisch-analytische Herangehensweise aus der Perspektive einer historischen politischen Soziologie vor. Während es vor dem Hintergrund der zugänglichen Quellen schwierig ist, den ursächlichen Prozess dieses Krieges genau zu bestimmen, wird versucht, vier Bedingungskomplexe dieses Prozesses zu benennen. Sie berücksichtigen sowohl die geschichtlichen Strukturierungen wie das eigentliche Konflikthandeln. Die Gleichzeitigkeit des Ungleichzeitigen und der postimperiale Habitus der politischen Klasse Russlands sind solche strukturierenden Komplexe des Prozesses, während die asymmetrische Figuration Russlands, der Ukraine und der USA sowie das Konflikthandeln im engeren Sinne dynamisierende Bedingungen des Prozesses sind. Der Beitrag schließt mit einem kritischen Ausblick auf die weitere Interpretation des Konflikts und ihre möglichen Effekte auf Krieg und Frieden.

Authors: Wegel Melanie , Baier Dirk
Published: September 2022

Die Covid-19 Pandemie stellte auch für die Institutionen des Freiheitsentzuges eine Herausforderung dar. Gesundheitlich mehrfach belastete InsassInnen, begrenzte räumliche Rahmenbedingungen und ein Doppelmandat zwischen Sicherheit und Betreuung stellten das Justizwesen vor die Herausforderung, die einschränkenden Präventionsmaßnahmen so umzusetzen, dass einerseits die Tagesstrukturen gewährleistet waren und zugleich ein Ausbruch der Covid-19 Pandemie in den Institutionen des Freiheitsentzuges verhindert werden konnte. Im Folgenden werden die Gelingensbedingungen der Pandemiebekämpfung im schweizerischen Freiheitsentzug genauer erläutert.
Mutterschaft als Ressource. Eine geographisch-intersektionale Perspektive auf den Ankommensprozess geflüchteter jesidischer Frauen
Authors: Enßle-Reinhardt Friederike
Published: September 2022

Bestehende Studien zur Lebenssituation geflüchteter Frauen verweisen auf eine Schlechterstellung dieser im Vergleich zu geflüchteten Männern. Dies wird vor allem durch familiäre Verpflichtungen, insbesondere Sorgearbeit für Kinder begründet. Anhand einer qualitativen, intersektionalen Forschung mit geflüchteten jesidischen Frauen, ehrenamtlichen Unterstützerinnen und Institutionenvertreterinnen in einer süddeutschen Mittelstadt ändert der Artikel den Blickwinkel. Eine geographische Analyse der Verhandlung von Zuschreibungen, die geflüchtete Frauen mit und ohne Kinder erleben, zeigt entlang von vier Räumen, dass Mutterschaft kontextabhängig unterschiedlich sichtbar wird und die eigene Handlungsmacht stärken kann. Der Artikel plädiert für eine differenzierte Sichtweise auf Mutterschaft im Ankommensprozess, die neben Herausforderungen auch eine greifbare Ressource darstellen kann, etwa als Zugang zu sozialen Kontakten und Institutionen.
Frauen afghanischer Herkunft auf dem Weg in den oberösterreichischen Arbeitsmarkt – Annäherung an eine Typisierung zur zielgerichteten Unterstützung
Authors:   Wetzelhütter,   Hasengruber,   Falkner-Matzinger,   Angerer
Published: September 2022

Die (aus)bildungsspezifische Charakteristik von Frauen afghanischer Herkunft, ihre Lebenssituation sowie die Verfügbarkeit von Ressourcen und den damit in Verbindung stehenden Herausforderungen und Gelingensfaktoren auf dem Weg in den Arbeitsmarkt sind wenig erforscht. Die Entwicklung entsprechender Maßnahmen gestaltet sich schwierig. Hierbei kann die im Beitrag vorgestellte Typologisierung dienlich sein. Diese ist auf Basis von Interviews und einer Fokusgruppe mit ExpertInnen sowie Gesprächen mit in Oberösterreich lebenden Afghaninnen mit Fluchterfahrungen entstanden. Die Ergebnisse zeigen: Es wird unterschiedlichste Unterstützung benötigt. Die Bedarfe hängen von Qualifikation, lebenssituationsspezifischen Rahmenbedingungen (z.B. Wohnen, Mobilität), sozialen Ressourcen, persönlichen Merkmalen und beruflichen Aspirationen ab. Davon ausgehend differenziert die Typologie, zur zielgerichteten Unterstützung, in Abstufungen ›chancenreiche‹ bis ›vulnerable‹ Afghaninnen auf dem Weg in den Arbeitsmarkt.
Role of Public-Private Partnerships in Primary Healthcare Services Worldwide: A Scoping Review
Authors: Ghasemi Mohammad , Amini-Rarani Mostafa , Shaarbafchi Zadeh Nasrin , Karimi Saeed
Published: September 2022

Background: The public health system is currently facing a shortage of resources, and the demand for healthcare has increased, indicating the need to use the capacities of other sectors through public-private partnership (PPP) strategies to improve the quantity and quality of health services. Objectives: The purpose is to identify PPPs' role in providing primary healthcare worldwide. Methods: This study was conducted in 2020. The Arksey O’Malley framework was used, along with a systematic literature search on five databases, including Web of Science (ISI), Scopus, Pubmed, ProQuest, and Google Scholar. Data were gathered from 2000 to 2020. Results: The findings presented in this study are reported based on 16 selected studies. The findings point to the positive impacts of cooperation between the public and private sectors in health care systems on matters of provision, coverage, and performance of services, as well as improvements in responsiveness to providers towards enhancing health referral systems. The provision of participatory services in countries varied according to their level of development, and further interactions between the government and the private sector resulted in better coverage and reduced inequality in service delivery. Conclusions: Public-private partnership is an effective way to achieve sustainable development goals. Public-private partnerships can be strengthened by integrating public and private sector facilities and aligning the interests and motivations of service providers with public health goals. Also, awareness of the plans and capacity of public and private sectors, along with conscious and mutual interaction, can strengthen health on a larger scale. Scientific approaches and correct participation can also relieve the part of governmental responsibilities to focus on more primary measures so that it can carry out its core tasks, including stewardship, policy-making, and supervision, with greater focus and power to facilitate the achievement of goals.
Environmental Philosophy at the Edges of Science
Authors: Norton Bryan G. ,   Philosophy Documentation Center
Published: September 2022

While environmental ethics has flourished and contributed to the discussion of environmental policy, other areas of philosophy (epistemology, for example), have been less in evidence in these discussions. In this paper, we explore a role for these neglected areas: they are best viewed as meta-level discussions of the conceptual and linguistic problems that arise as scientists develop models at the edges of scientific fields relevant to our understanding of environmental problems and possible solutions. The relevant fields, which might differ depending on the specific environmental problem being addressed, can be thought of as a collection of “philosophies of ____” where the blank stands for one of the relevant disciplines, such as biology, ecology, or economics. We eschew the typical arguments regarding which models are correct in favor of a pragmatic/pluralistic approach to understanding scientific models. This pragmatic approach softens interdisciplinary conflicts as Rudolf Carnap’s Principle of Tolerance (linguistic conventionalism) urges an experimental approach to developing linguistic frameworks for differing situations. This approach is illustrated by an examination of the models proposed by ecologists and economists.
Establishing the Test-Retest Reliability and Minimal Detectable Change of the Multiple Sclerosis Resiliency Scale
Authors: Gromisch Elizabeth S. , Turner Aaron P. , Neto Lindsay O. , Ruiz Jennifer A. , Lo Albert C. , Agresta Thomas , Foley Frederick W.
Published: September 2022

BACKGROUND

The Multiple Sclerosis Resiliency Scale (MSRS) was designed to assess factors connected to resilience when facing MS-related challenges. Although the MSRS has demonstrated good internal consistency and construct validity, its test-retest reliability has yet to be established. Identifying the minimal detectable change (MDC) of the scale will also improve its utility as an outcome measure for resilience-based interventions. This study aimed to determine the test-retest reliability and MDC of the MSRS.

METHODS

Participants were 62 persons with MS who completed the MSRS twice, with a mean ± SD of 16.60 ± 3.97 days (range, 14–30 days) between assessments. Test-retest reliability was evaluated using a 2-way, random-effects, single-measurement intraclass correlation coefficient (ICC), with agreement between time 1 and time 2 visualized with a Bland-Altman plot. The MDC was calculated using the standard error of measurement with a 95% CI.

RESULTS

At time 1, the mean ± SD MSRS score was 77.19 ± 11.97 (range, 45.83–97.00); at time 2, the mean ± SD score was 76.38 ± 12.75 (range, 46–98). The MSRS total score had good test-retest reliability (ICC = 0.88), with the subscale ICCs ranging from 0.77 (MS Peer Support) to 0.93 (Spirituality). The MDC for the total score was 11.95.

CONCLUSIONS

These findings suggest that the MSRS has good test-retest reliability and that persons with MS with a difference of 12 points or more between assessments have experienced a reliable change. The results support the utility of the MSRS as a potential outcome measure for MS-related resilience.
On the Typology of the Negative Image of an Anarchist in Graphic Art at the Turn of the XIX-XX centuries.
Authors: Velásquez Sabogal Paúl Marcelo
Published: September 2022

The subject of the study is the thematic and iconographic directions of the negative interpretation of the image of an anarchist in the printed culture of the turn of the XIX-XX centuries. The object of the study is graphic works published in periodicals of various ideological trends and devoted to the representation of the image of an anarchist. Three main directions of such interpretation are identified and described, namely, the criminal-terrorist, the mentally ill and the immigrant, whose iconographic features are analyzed in the light of socio-political and historical-cultural conditions of each specific context. Among the reviewed publications should be mentioned: L'Assiette au beurre, Le Petit Journal (France), Freie Jugend (Germany), Het Volk (Netherlands), La Obra, El Peludo (Argentina), Star (New Zealand) and The Washington Post (USA).   The scientific novelty of the work consists in the fact that for the first time in modern art criticism, the process of forming the negative archetype of an anarchist is considered and analyzed on the basis of its graphic representation. Thus, a methodological basis is being created for studying the types of classification of the anarchist image. The methods used in the work are as follows: source studies, iconographic, artistic and stylistic analysis. The results of the study reveal the specifics of one of the interpretations of the image of an anarchist of the turn of the XIX-XX centuries, which has its roots in both right and left political trends, whose approaches to anarchism are based on socio-legal and medical sciences, among which criminology stands out. The latter, led by Cesare Lombroso, played a primary place in the mythologization, which is still active today, of the image of an anarchist as a carrier of chaos.
Myth as a manifestation of the functional asymmetry of the human
Authors: Stavitskiy Andrey Vladimirovich
Published: September 2022

The subject of the article is the problem of the functioning of myth in the context of a dialectically constructed functional asymmetry of culture, language and thinking, where myth and science actively interact complementing each other. The purpose of the article is to consider the causes, nature and mechanism of this interaction, to identify the features of its manifestation and to show its positive sides. As a methodological support for the research, approaches and principles of non-classical science were used, allowing to move away from the classical attitudes of mythology and look at it more broadly, considering the myth not as a legend about gods and heroes, but as a cultural universal and a property of consciousness. The main conclusions of the article are reduced to understanding the importance of the perception of myth in the mode of non-classical mythology developed in the twentieth century, where myth is understood as a semantic matrix of culture responsible for the formation of a field of value meanings. This makes it possible to better understand the role of myth and myth-making in the structure of culture and consciousness, as well as to consider the epistemological resource of myth in scientific creativity, which is clearly underestimated in science, creating a complex system of cognitive dependencies resembling the interaction of the left and right hemispheres of the brain, which form the necessary variety of functional capabilities of human intelligence, working on the principle of mutual complementarity.
Stability switches in a linear differential equation with two delays
Authors: Hata Yuki , Matsunaga Hideaki
Published: September 2022

This paper is devoted to the study of the effect of delays on the asymptotic stability of a linear differential equation with two delays \[x'(t)=-ax(t)-bx(t-\tau)-cx(t-2\tau),\quad t\geq 0,\] where \(a\), \(b\), and \(c\) are real numbers and \(\tau\gt 0\). We establish some explicit conditions for the zero solution of the equation to be asymptotically stable. As a corollary, it is shown that the zero solution becomes unstable eventually after undergoing stability switches finite times when \(\tau\) increases only if \(c-a\lt 0\) and \(\sqrt{-8c(c-a)}\lt |b| \lt a+c\). The explicit stability dependence on the changing \(\tau\) is also described.

In the era of highly thin, multi-functional and integrated electronic devices, it will inevitably lead to the heat accumulation inside the composite material, thereby seriously affecting the operation stability and service life of the equipment. How to realize the rapid and efficient heat conduction and heat dissipation of dielectric materials has become a bottleneck problem restricting the further development of electronic devices. The intrinsic thermal conductivity of traditional polyimide is low, which limits its application in electrical equipment, smart grid and other fields. The development of new high thermal conductivity polyimide dielectric film materials has become the focus of research. This paper introduces the thermal conduction mechanism of composite materials, summarizes the research progress and development status of thermally conductive polyimide films in recent years, and focuses on the effects of thermally conductive fillers, interface compatibility, and molding process of the thermal conductivity of materials. Finally, some key scientific and technical issues in the research are summarized and prospected in combination with the future development needs of thermally conductive polyimide composite dielectric materials.

Um olhar epistemológico sobre as controvérsias do estado laico e da laicidade no Brasil Contemporâneo
Authors:   Faculdades EST, Gabatz Celso , Angelin Rosángela , Hahn Noli Bernardo , Castro Sartori Alana Taíse
Published: September 2022

O debate acerca do Estado laico e da laicidade no Brasil rende muitas reflexões, não somente em questões concernentes aos meandros da intolerância religiosa, mas, principalmente, enseja um olhar mais aguçado em relação aos Poderes Constituídos: Executivo, Legislativo e Judiciário. Por meio de uma abordagem hipotética dedutiva, desenvolvida com a consulta a documentos históricos, jurídicos, acadêmicos e notícias do cenário nacional, esta abordagem procura traçar um percurso epistemológico que busca refletir sobre as práticas governamentais na esfera pública brasileira contemporânea que evidenciam controvérsias no tocante a garantia da laicidade e da preservação constitucional de um Estado laico. Os resultados demonstram a presença contundente de dogmas religiosos na esfera pública. Tanto o Poder Executivo, quanto os Poderes Legislativo e Judiciário se posicionam de maneira paradoxal. Ora assumindo uma premissa alinhada com os parâmetros constitucionais inerentes à dimensão legal laica, respeitando certas diretrizes da laicidade, ora as afrontando, de forma explicita ou velada, a depender das situações e dos interesses, não corroborando para a consolidação de um ideal democrático.
Aproximações teológico-políticas entre Agamben, Schmitt e Foucault Teología económica, teología política y poder pastoral
Authors: Rosa Alex
Published: September 2022

Este artículo es una revisión bibliográfica sobre el concepto de Teología Política, buscando establecer similitudes y diferencias con sus temas relacionados, Teología Económica y Poder Pastoral. Trabajados respectivamente por Carl Schmitt, Giorgio Agamben y Michel Foucault, los conceptos abordan la relación entre religión y estado, oscilando entre perspectivas centradas en la relación de soberanía estatal y enfoques en el campo de las técnicas de poder. Guiada por el método inductivo, la investigación utilizó los principales trabajos de los autores, interpretándolos de manera heurística y preocupándose por establecer y demarcar las posibles relaciones entre ellos, sin señalar ninguno como definitivo. Contribuyendo a la discusión sobre la influencia de las Iglesias en la sociedad y en el Estado (supuestamente neutrales), especialmente en América Latina, la investigación mapeó elementos teóricos que ayudan a comprender la influencia de las Iglesias en modalidades: a veces en su trayectoria institucional - acercándose los enfoques centrados en la derecha, a veces a través de representantes electos y / o formación de opinión popular a través de los fieles, enfoques que se orientan por técnicas de poder.
Assessment of Choroidal Thickness in Acute Central Serous Chorioretinopathy Using Swept Source Optical Coherence Tomography: A Case-control study
Authors: Bamel Arjun , Shah Parag K , Bharadwaj Rahul , Dhawan Aeshvarya , Singh Anupam
Published: September 2022

Introduction: Central Serous Chorioretinopathy (CSCR) is a disease characterised by localised Neurosensory Detachment (NSD) with or without focal Pigment Epithelial Detachments (PED) and altered Retinal Pigment Epithelium (RPE). Since CSCR being a pachychoroid entity the visualisation and evaluation of choroidal vessels have shown that vascular layers are altered in the disease process. Aim: To assess Sub Foveal Choroidal Thickness (SFCT), in acute Central Serous Chorioretinopathy (CSCR) patients in both affected and fellow unaffected eyes using Swept Source Optical Coherence Tomography (SS-OCT), and to compare these with age-matched control group. Materials and Methods: This was a hospital-based casecontrol study, conducted between July 2018 and May 2019 at Outpatient Department (OPD) of Aravind Eye Hospital, Coimbatore. Total of 41 patients and 41 controls from OPD were included. Uncorrected Visual Acuity (UCVA) and Best Corrected Visual Acuity (BCVA) were measured on Snellen’s chart. After pupil dilatation, posterior segment evaluation with slit lamp bio microscopy using a 90D lens and documentation with fundus photograph were done. All subjects were examined using SSOCT which was done for both the eyes. Descriptive analysis such as mean, standard deviation and percentage were used to exhibit the clinical parameters. Independent t-test analysis was more suitable for this data. All the statistical tests were examined with 5% (p-value≤0.05) level of significance. Results: The age (mean±SD) of cases and controls were 38.44±6.14 years and 37.21±2.72 years, respectively. The mean SFCT of affected and unaffected fellow eye of cases were 465.39±60.02 μm and 407.12±57.29 μm respectively, (p-value<0.001). The mean SFCT of affected eyes of cases and control group eyes were 465.39±60.02 μm and 267.5±34.40 μm respectively, (p-value<0.001). Conclusion: The choroid was significantly thicker in affected as well as unaffected eye of CSCR patient. This implies that the CSCR affect the choroidal thickness in both affected as well as unaffected eye of patient as compared to control group.
Investigation of the uncertainty of initial and boundary conditions in the hindcasts of flow fields over urban areas using a mesoscale numerical weather prediction model
Authors: Kawamoto Yoichi
Published: September 2022

Numerous studies have been conducted using mesoscale numerical weather prediction models to analyze the thermal and wind environments of urban areas around the world. However, weather predictions are highly sensitive to initial conditions. This is the so‐called “butterfly effect.” In this study, the effects of initial and boundary conditions upon the reproduction accuracy for wind environments (particularly for the sea breeze) over the Fukuoka metropolitan area were investigated by varying (i) the objective analysis data used for the initial and boundary conditions and (ii) the length of the spin‐up calculation period. The results of the simulation were compared with surface observations and Doppler LIDAR observations of the airflow field. The accuracy is thought to decrease under an increase in the length of the spin‐up calculation period; however, this was not the case in this study. In terms of the differences in the objective analysis data, no clear trend was observed from the comparisons with surface observations; however, slight differences were observed when comparing with the Doppler LIDAR. The lagged average forecasting method (which reduces the uncertainty of the initial conditions by shifting the calculation start time) was also adopted; the ensemble‐averaged results showed a good correspondence with the observations.

Purpose

The 4D computed tomography (CT) simulation is an essential procedure for tumors exhibiting breathing‐induced motion. However, to date there are no established guidelines to assess the characteristics of existing systems and to describe meaningful performance. We propose a commissioning quality assurance (QA) protocol consisting of measurements and acquisitions that assess the mechanical and computational operation for 4D CT with both phase and amplitude‐based reconstructions, for regular and irregular respiratory patterns.

Methods

The 4D CT scans of a QUASAR motion phantom were acquired for both regular and irregular breathing patterns. The hardware consisted of the Canon Aquilion Exceed LB CT scanner used in conjunction with the Anzai laser motion monitoring system. The nominal machine performance and reconstruction were demonstrated with measurements using regular breathing patterns. For irregular breathing patterns the performance was quantified through the analysis of the target motion in the superior and inferior directions, and the volume of the internal target volume (ITV). Acquisitions were performed using multiple pitches and the reconstructions were performed using both phase and amplitude‐based binning.

Results

The target was accurately captured during regular breathing. For the irregular breathing, the measured ITV exceeded the nominal ITV parameters in all scenarios, but all deviations were less than the reconstructed slice thickness. The mismatch between the nominal pitch and the actual breathing rate did not affect markedly the size of the ITV. Phase and normalized amplitude binning performed similarly.

Conclusions

We demonstrated a framework for measuring and quantifying the initial performance of 4D CT simulation scans that can also be applied during periodic QAs. The regular breathing provided confidence that the hardware and the software between the systems performs adequately. The irregular breathing data suggest that the system may be expected to capture in excess the target motion and geometry, but the deviation is expected to be within the slice thickness.
Understanding entrance‐air‐kerma as a quality‐control metric for dual‐energy x‐ray absorptiometry

Purpose

The low exposures, unique x‐ray beam geometry, and scanning design in dual‐energy x‐ray absorptiometry (DXA) make measurement and quality‐control strategies different from traditional x‐ray equipment. This study examines the dependence of measured entrance‐air‐kerma (EAK) on both dose sensor type and scan length. The feasibility of using EAK to compare scanner output between different scan modes, individual scanners, and scanner platforms was also established. Finally, the congruence between measured and vendor‐reported EAK was analyzed.

Methods

Four Hologic DXA scanners at two institutions and all four available scan modes were tested. EAK was measured directly by three types of Radcal dose sensors: 60‐cc pancake ion‐chamber (IC), 180‐cc pancake IC, and solid‐state detector. The coefficient of variation (COV) was used to assess the dependence of EAK on scan length. Variations in EAK between the types of dose sensors as well as measured versus vendor‐reported values were evaluated using Bland–Altman analysis: mean ±95% prediction interval (PI): 1.96σ.

Results

Dose sensor variations in EAK were minimal, with a −3.5 ± 3.5% (mean ±95% PI) percent difference between the two sizes of IC's. The solid‐state detector produced highly similar measurements to the 180‐cc IC. These small differences were consistent across all scanners and all scan modes tested. Neither measured nor vendor‐reported EAK values were found to show relevant dependence on scan length, with all COV values ≤4%. Differences between measured and reported EAK were higher at −6 ± 48%. Likely errors in vendor‐reported EAK calculations were also identified.

Conclusion

It is feasible to quantify DXA scanner stability using EAK as a quality‐control metric with a variety of solid‐state and IC dose sensors, and the scan length used is not critical. Although vendor‐reported EAK was consistent among scanners of the same platform, measured EAK varied significantly from scanner to scanner. As a result, measured and reported EAK may not always be comparable.

The optimized design of 3D‐printed continuous fiber reinforced composites (CFRCs) at the structural level provides the possibility of further performance improvement. Herein, a design scheme of three‐point bending heterogeneous 3D‐printed continuous carbon fiber reinforced composites (CCFRCs) based on fiber volume fraction is reported. It is found experimentally that, compared with the pure polylactic acid (PLA), the force bearing capacity of the three designed CCFRCs with different fiber volume fractions increases by 190.46%, 222.36%, and 253% with the raise of fiber content, and flexural modulus increases by 369.32%, 426.05%, and 549.41%, respectively. Another discovery is that the spatial arrangement of fibers is also an important factor affecting the bending performance, and it is concluded that the bottom region's fiber content has a significant effect on the bending performance, with the same fiber content (10.20%), the load withstood with a larger fiber volume fraction setting of the bottom layer is 117.69% of that with a smaller one. The failure modes are observed using cone beam computed tomography and the main failure causes of the structures are analyzed. Herein, a solution for the lightweight structure design is provided as well as improves its comprehensive performance, further promoting the potential application of 3D‐printed CCFRCs.

High‐entropy alloys (HEAs) or complex concentrated alloys (CCAs) offer a huge research area for new material compositions and potential applications. Since the combination of several elements sometimes leads to unexpected and unpredictable material properties. In addition to the element combinations, the optimization of the element proportions in CCAs and HEAs is also a decisive factor in tailoring desired material properties. However, it is almost impossible to achieve the composition and characterization of CCAs and HEAs with a sufficient number of compositions by conventional experiments. Therefore, an optimized high‐throughput magnetron sputtering synthesis to fabricate a new HEA gradient layer of six elements is presented. With this approach, the compositional space of the HEA system CrMoNbTaVW can be studied in different subsections to determine the influence of the individual elements and their combinations on the structure, morphology, and physical properties (hardness and resistivity). It is found that the Cr‐, Ta‐, and W‐rich phases, which have a grain size of 10–11 nm, exhibit the hardest mechanical properties, whereas V‐, Ta‐, and Cr‐rich compounds exhibit the highest electrical resistivity. The combination of high‐throughput synthesis, automated analysis tools, and automated data interpretation enables rapid and time‐efficient characterization of the novel CrMoNbTaVW gradient film.

Wire and arc additive manufacturing (WAAM) has the potential to significantly reduce material waste due to the milling of components made of TiAl6V4 (Ti‐64). To keep up with the market development, this resource‐efficient technology is becoming increasingly important to achieve climate policy goals. Therefore, this study not only focuses on the influence of different process parameters, such as torch and wire feed speed, but also different gas mixtures on the microstructure and related mechanical properties, as well as on the scalability by investigating single‐ to multilayer welded structures. The wire feed speed is found to have a major influence on the geometry and mechanical properties. The use of different process gases, i.e., argon (Ar), helium (He), and a mixture of 70% He and 30% Ar neither significantly affect the microstructure nor the mechanical properties. It is also found that a solution heat treatment followed by an annealing step degrades mechanical properties, while an ordinary stress‐relief heat treatment leads to improved mechanical properties. It is shown that by adapting WAAM process and heat treatment parameters, mechanical properties of additively produced specimens can be achieved, which are fully comparable to milled components.
