Introduction: Disease-related undernutrition is highly prevalent and requires timely intervention. However, identifying undernutrition often relies on physician judgment. As Internal Medicine wards are the backbone of the hospital setting, insight into the prevalence of nutritional risk in this population is essential. We aimed to determine the prevalence of nutritional risk in Internal Medicine wards, to identify its correlates, and to assess the agreement between the physicians’ impression of nutritional risk and evaluation by Nutritional Risk Screening 2002.Material and Methods: A cross-sectional multicentre study was performed in Internal Medicine wards of 24 Portuguese hospitals during 2017. Data on demographics, previous hospital admissions, primary diagnosis, and Charlson comorbidity index score were collected. Nutritional risk at admission was assessed using Nutritional Risk Screening 2002. Agreement between physicians’ impression of nutritional risk and Nutritional Risk Screening 2002 was tested by Cohen’s kappa.Results: The study included 729 participants (mean age 74 ± 14.6 years, 51% male). The main reason for admission was respiratory disease. Mean Charlson comorbidity index score was 5.8 ± 2.8. Prevalence of nutritional risk was 51%. Nutritional risk was associated with admission during the previous year (odds ratio = 1.65, 95% confidence interval: 1.22 - 2.24), solid tumour with metastasis (odds ratio = 4.73, 95% confidence interval: 2.06 - 10.87), any tumour without metastasis (odds ratio = 2.04, 95% confidence interval:1.24 - 3.34), kidney disease (odds ratio = 1.83, 95% confidence interval: 1.21 - 2.75), peptic ulcer (odds ratio = 2.17, 95% confidence interval: 1.10 - 4.25), heart failure (odds ratio = 1.51, 95% confidence interval: 1.11 - 2.04), dementia (odds ratio = 3.02, 95% confidence interval: 1.96 - 4.64), and cerebrovascular disease (odds ratio = 1.62, 95% confidence interval: 1.12 - 2.35). Agreement between physicians’ evaluation of nutritional status and Nutritional Risk Screening 2002 was weak (Cohen’s kappa = 0.415, p < 0.001).Discussion: Prevalence of nutritional risk in the Internal Medicine population is very high. Admission during the previous year and multiple comorbidities increase the odds of being at-risk. Subjective physician evaluation is not appropriate for nutritional screening.Conclusion: The high prevalence of at-risk patients and poor subjective physician evaluation suggest the need to implement mandatory nutritional screening.

Published: June 2021

Introduction: In Portugal, extracorporeal membrane oxygenation (ECMO) is used in pediatric patients since 2010. The aim of this study was to describe the clinical characteristics of patients, indications, complications and mortality associated with the use of ECMO during the first 10-years of experience in the Pediatric Intensive Care Unit located in Centro Hospitalar Universitário Lisboa Norte.Material and Methods: Retrospective observational cohort study of all patients supported with ECMO in a Pediatric Intensive Care Unit, from the 1st of May 2010 up to 31st December 2019.Results: Sixty-five patients were included: 37 neonatal (≤ 28 days of age) and 28 pediatric patients (> 28 days). In neonatal cases, congenital diaphragmatic hernia was the main reason for ECMO (40% of neonatal patients and 23% of total). Among pediatric patients, respiratory distress was the leading indication for ECMO (47% of total). The median length of ECMO support was 12 days. Clinical complications were more frequent than mechanical complications (65% vs 35%). Among clinical complications, access site bleeding was the most prevalent with 38% of cases. The overall patient survival was 68% at the time of discharge (65% for neonatal and 71% for pediatric cases), while the overall survival rate in Extracorporeal Life Support Organization registry was 61%. The number of ECMO runs has been increasing since 2011, even though in a non-linear way (three cases in 2010 to 11 cases in 2019).Discussion: In the first 10 years we received patients from all over the country. Despite continuous technological developments, circuitrelated complications have a significant impact. The overall survival rate in the Pediatric Intensive Care Unit was not inferior to the one reported by the Extracorporeal Life Support Organization.Conclusion: The overall survival of our Pediatric Intensive Care Unit is not inferior to one reported by other international centers. Our experience showed the efficacy of the ECMO technique in a Portuguese centre.

L'entrée des Croisés à Constantinople
Authors: Chimot Jean-Philippe
Published: June 2021

Inquiet de son avenir, le gouvernement de la Monarchie de Juillet (1830-48) invente une sorte de roman national en peinture, à Versailles notamment. Il en attend une légitimation indirecte. Dans l'épisode des Croisades (12°et 13° siècles), réévalué et chanté par le romantisme, Delacroix reçoit une commande : l'Entrée des Croisés à Constantinople (1204), livrée en 1840. On analyse ici comment, d'un épisode peu glorieux (en fait un pillage), il développe, par sa poétique plastique et chromatique, toutes les sombres et éclatantes contradictions.

Published: June 2021

Distributed fiber optic vibration sensors based on Φ-OTDR using Rayleigh backscattering of highly coherent light source pulses are very popular type in the area of sensors due to many attractive features, mainly due to its distributed manner of sensing, i.e. they can operate as thousands of local sensors simultaneously. The paper summarizes and describes several important modifications of the original sensor scheme to enhance its key performance parameters and to extend its application potential. A multi-fiber sensor form was proposed. Single- and two-fiber sensors were designed, constructed and tested both in the laboratory and in a real environment. Variants of two-fiber sensor utilizing optical switches for the sensor flexibility enhancement are proposed and their applications are described.
Theoretical Investigation of Subluminal Particles Endowed with Imaginary Mass
Authors: Nanni Luca
Published: June 2021

In this article, the general solution of the tachyonic Klein-Gordon equation is obtained as a Fourier integral performed on a suitable path in the complex \omega-plane. In particular, it is proved that under given boundary conditions this solution does not contain any superluminal components. On the basis of this result, we infer that all possible spacelike wave equations describe the dynamics of subluminal particles endowed with imaginary mass. This result is validated for the Chodos equation, used to describe the hypothetical superluminal behaviour of neutrino. In this specific framework, it is proved that the wave packet propagates in spacetime with subluminal group velocities and that for enough small energies it behaves as a localized wave.
Relativistic Scalar Feld Under the EﬀEcts of Lorentz Symmetry Violation Subject to Cornell-Type Potential
Authors: Ahmed Faizuddin
Published: June 2021

We investigate a scalar particle under Lorentz symmetry breaking eﬀects determined by a tensor out of the Standard Model Extension (SME) in the presence of a Cornell-type potential by modifying the mass term M → M +S in the KG-equation. The ﬁeld conﬁguration is such that a Coulomb-type radial electric ﬁeld and a constant magnetic ﬁeld can be induced by Lorentz symmetry violation, and analyze the behaviour of a scalar particle. One can see that the bound states solution to the KG-equation under the consider eﬀects can be achieved, and a quantum eﬀect characterized by the dependence of charge density distribution parameter on the quantum numbers of the system is observed.

Authors: Vuorinen Ilkka , Oksanen Atte , Savolainen Iina , Sirola Anu , Kaakinen Markus , Paek Hye-Jin , Zych Izabela
Published: June 2021

Background and aims Loneliness and a low sense of mastery have been associated with excessive gambling, but the underlying processes of these relationships remain unstudied. Because psychological distress can increase vulnerability to excessive gambling, we investigated its mediating role in these relationships among young people. To meet the need for cross-country research, we also observed how these relationships occur in four countries with different cultures. Design, setting and participants Demographically balanced cross-sectional survey data were collected for 15–25-year-olds in Finland (n=1200; 50% male), the United States (n=1212; 49.8% male), South Korea (n=1192; 49.6% male) and Spain (n=1212; 51.2% male). Measurements Excessive gambling was measured with the South Oaks Gambling Screen, psychological distress was assessed with the 12-Item General Health Questionnaire, loneliness was measured with the Three-Item Loneliness Scale and low sense of mastery was assessed with the Pearlin Mastery Scale. Associations were examined first using zero-inflated negative binomial regression analyses with excessive gambling as the outcome. In addition, path analyses were performed to study how loneliness and low sense of mastery relate to excessive gambling, with psychological distress as the mediating variable. Findings Loneliness and low sense of mastery were associated indirectly with excessive gambling via psychological distress in all country samples. Low sense of mastery was also directly associated with excessive gambling. There was a direct association between loneliness and excessive gambling only in samples from South Korea and Spain. Conclusions Psychological distress is an important factor in understanding how loneliness and sense of mastery relate to gambling.
Why Recessive Lethal Alleles Have Not Disappeared?
Authors: Jormakka Jorma , Ghosh Sourangshu
Published: June 2021

The article derives the probability for lethal recessive alleles in the case of recessive disadvantage or advantage. It is shown that the recessive advantage of a lethal gene can be detected by the ratio of heterozygotes and homozygotes. This demonstrates that the higher IQ of certain ethnic groups cannot be explained by the recessive advantage of lethal genes. The article shows that lethal genes can survive in the population if some lineages of families have much more children than the average.
Mass Spectrometry-based Proteomic and Immunoproteomic Analyses of the Candida albicans Hyphal Secretome Reveal Diagnostic Biomarker Candidates for Invasive Candidiasis

Published: June 2021

Invasive candidiasis (IC) is associated with high morbidity and mortality in hospitalized patients if not diagnosed early. Long-term use of central venous catheters is a predisposing factor for IC. Hyphal forms of Candida albicans (the major etiological agent of IC) are related to invasion of host tissues. The secreted proteins of hyphae are involved in virulence, host interaction, immune response, and immune evasion. To identify IC diagnostic biomarker candidates, we characterized the C. albicans hyphal secretome by gel-free proteomic analysis, and further assessed the antibody-reactivity patterns to this subproteome in serum pools from 12 patients with non-catheter-associated IC (ncIC), 11 patients with catheter-associated IC (cIC), and 11 non-IC patients. We identified 301 secreted hyphal proteins stratified to stem from the extracellular region, cell wall, cell surface, or intracellular compartments. ncIC and cIC patients had higher antibody levels to the hyphal secretome than non-IC patients. Seven secreted hyphal proteins were identified to be immunogenic (Bgl2, Eno1, Pgk1, Glx3, Sap5, Pra1 and Tdh3). Antibody-reactivity patterns to Bgl2, Eno1, Pgk1 and Glx3 discriminated IC patients from non-IC patients, while those to Sap5, Pra1 and Tdh3 differentiated between cIC and non-IC patients. These proteins may be useful for development of future IC diagnostic tests.
Eﬀects of Lorentz Symmetry Breaking and scalar Potential on Relativistic Quantum Oscillator
Authors: Ahmed Faizuddin
Published: June 2021

In this paper, we investigate the behaviour of a relativistic quantum oscillator under the eﬀects of Lorentz symmetry violation determined by a tensor (KF)µναβ out of the Standard Model Extension. We analyze the quantum system under a Coulomb-type radial electric ﬁeld and a uniform magnetic induced by Lorentz symmetry breaking eﬀects under a Cornell-type potential, and obtain the bound states solution by solving the Klein-Gordon oscillator. We see a quantum eﬀect due to the dependence of the angular frequency of the oscillator on the quantum numbers of the system, and the energy eigenvalues and the wave-function of the oscillator ﬁeld get modiﬁed by the Lorentz symmetry breaking parameters as well as due to the presence of Cornell-type potential.
Real-Time Smoke Simulation based on Vortex Method
Authors: Wan Fei , Zhang Jingpu , Guo Lizheng , Liu Yunchang
Published: June 2021

In this paper, we use three different experimental methods (particle method, grid method and hybrid method) to model and simulate the smoke from the perspective of fluid dynamics. Through the comparison of different methods, we conclude: The particle method can avoid the numerical dissipation problem caused by grid calculation, but it also brings problems such as the distortion of the trajectory of the example. The grid method is accurate in calculation, but it is prone to numerical dissipation and loss of details. Finally, we choose the hybrid method to store the vorticity in the form of particles in vortex particles, avoiding the numerical dissipation problem caused by the use of grids, and including rich turbulence, which perfectly shows the simulation effect of smoke.

Published: June 2021

Brazil chicken production is around 13 million tons and about a third is exported to over 150 countries, placing Brazil as the world largest chicken meat producer, and therefore it is crucial to follow the legislation of all importer markets. This study aimed at evaluating ten chemical residues (amoxicillin, bacitracin, colistin, dinitolmide + zoalene, spectinomycin, roxarsone, tiamulin, tylosin, trenbolone acetate and virginiamycin) in chicken breast and one (halofuginone hydrobromide) in chicken liver. Most of these compounds are not covered by National Residues and Contaminants Control Plan (PNCRC), although they are mandatory to export chicken meat worldwide. A total of 2580 samples were collected from 45 industries and submitted to analyte extraction and chromatographic verification of compliance in an accredited laboratory. The results showed that no compound exceeded the maximum residue limits established by worldwide legislation. All results were below the method detection limit, thereby confirming the capability of Brazilian chicken meat plants in complying to foreign markets. Our results can provide occurrence trends of veterinary drug from poultry products in Brazil.

Authors: Stătescu Carmen , Stoica Doru , Deaconu Andrei , Gavrilă Bogdan Ion , Trăistaru Magdalena Rodica , Bălșeanu Tudor Adrian
Published: June 2021

Background and Objectives: Sports medicine, orthopaedic and rehabilitation physicians use gait analysis and goniometry to evaluate and diagnose patients with neuro-musculo-skeletal diseases. Goniometry is a measuring method that shows the joint’s range of motion. Three-dimensional goniometry has been used in order to assess the patients in a kinematic manner, but they are not affordable, so, phone apps come handy to any orthopaedic or rehabilitation physician so we can have a clear image of the progress made by the patient after the rehabilitation program or should something happen and the patient cannot come to the facility, such as the Covid-19 pandemic, when some orthopaedic and most of the rehabilitation facilities have been temporarily closed. Midstance has been chosen as the moment of the gait evaluation in this paper since it has an important role in stability. The objective of this paper is to figure out if the measurements taken during midstance at the knee joint of the subjects can be statistically significant and used during usual examinations. Materials and Methods: Four groups of subjects: patients suffering from hip, knee, hip and knee osteoarthritis and a control group volunteered their participation, being asked to normally walk while their gait was recorded and uploaded into Angles App – a phone based videogoniometer. Results: Patients suffering from hip osteoarthritis have a higher knee angle on the right side than the ones suffering from knee osteoarthritis, hip and knee osteoarthritis and the control group. Female patients suffering from hip osteoarthritis also presented a more flexed knee than the ones suffering from knee osteoarthritis and the ones in the control group, the knee flexion presenting itself as a compensation mechanism. Conclusion: Video goniometry can help us make an orthopaedic, rehabilitation or neurology database for each assessment with constant updates of the evolution of the osteoarthritis patient’s treatment.
Relativistic Spin-0 Particle Under Linear Central Potential Eﬀects Induced by Lorentz Symmetry Violation
Authors: Ahmed Faizuddin
Published: June 2021

In this work, we investigate the behaviour of a relativistic scalar particle in the background of the Lorentz symmetry violation determined by a tensor (KF)µναβ out of the Standard Model Extension. A linear electric ﬁeld and a uniform magnetic can be induced by the violation of the Lorentz symmetry breaking eﬀects, and analyze the behaviour of the scalar particle. We see that the analytical solution to the KG-equation can be achieved, and a quantum eﬀect characterized by the dependence of the magnetic ﬁeld on the quantum numbers is observed
Construction of Differentiated Periodic Freight Train Paths in Dense Mixed Traffic
Authors: Drábek Michal , Janoš Vít
Published: June 2021

The article is focused on detailed framework process for hierarchized construction of periodic freight train paths (PFTPs) – allocation of pre-arranged railway capacity to freight rail operators. The framework process considers fluctuations in demand for capacity from freight rail opera-tors, so the quality of a freight train path is related with its construction priority. Introduced framework process aims to offer freight rail operators attractive train paths, with low number of scheduled stops, and this way enhance competitiveness and decrease energy consumption of freight railway as a factor for sustainable development. The proposed generic process is in-tended for all time horizons of capacity allocation. Correctness of the framework process is tested on the example of mainline Prague – Dresden, in the context of prospective (denser) mod-el passenger timetable.
Linear Central Potential Eﬀects Induced by Lorentz Symmetry Violation on Spin-0 Particle Under Coulomb-type scalar Potential
Authors: Ahmed Faizuddin
Published: June 2021

In this work, quantum dynamics of a spin-0 particle under the eﬀects of Lorentz symmetry violation in the presence of Coulombtype non-electromagnetic potential $(S(r) ∝ \frac{1}{r})$ is investigated. The non-electromagnetic (or scalar) potential is introduced by modifying the mass term via transformation $M → M + \frac{η_c}{r}$ in the relativistic wave equation. The linear central potential induced by the Lorentz symmetry violation is a linear radial electric and constant magnetic ﬁeld and, analyze the eﬀects on the spectrum of energy and the wave function

Coronavirus Disease 2019 (COVID-19) is the pandemic challenge of the last year. Cardiovascular involvement is one of the main characteristics of this disease. Due to endothelial damage, consequent phlogosis may increase a thrombosis risk. Cardiac injury may occur in different ways. However, an ischemic involvement of the cardiovascular system is rarely implied. In this regard, direct and indirect effects of COVID-19 are described. Nonetheless, the possible evaluation of the cardiovascular system may require different modalities. The cardiovascular evaluation may be different in emergency compared to critical care, requiring different tools for each setting. The aim of this review is to explore these modalities according to the different involvement of the cardiovascular system..
Physician Assistant Roles in Prevention and Management of Anterior Cruciate Ligament Injury
Authors: Crandall Katherine
Published: June 2021

With incidence of anterior cruciate ligament (ACL) injuries on the rise and a predicted impending shortage of physicians in medical fields, including orthopaedics, demand could soon outweigh supply for optimal care of these injuries. Physician assistants (PAs) are uniquely suited to care for patients in the screening, prevention, and management of ACL injuries. PAs frequently practice in primary care and in this setting can screen for at-risk patients and promote preventative techniques such as neuromuscular training. Primary care PAs can perform patient education about preventative measures and provide resources on a variety of available prevention programs that exist which aim to decrease the likelihood of ACL injury. Primary care PAs frequently use standardized scales or questionnaires in clinic to screen for health risks in their patients such as the Patient Health Questionnaire-9 (PHQ-9) for depression; the creation of a similarly standardized screening tool which assesses for ACL injury risk factors may be beneficial to aid primary care PAs in performing such screenings moving forward. Recovery from an ACL injury, regardless of operative or conservative management, can be a lengthy and complex process that is defined by months of follow-up appointments, rehabilitation exercises, and psychological management. Psychological impairment is a vital component in ACL injury recovery and has been identified as a preeminent factor in prolonging or inhibiting return to sport. By using available psychological measurement tools such as the ACL-Return to Sport after injury, as well as the patient education and counseling skills emphasized in their training, PAs can incorporate a psychologically based approach in management to promote a patient’s safe and timely return to sport. Maximizing efficiency and effectiveness of ACL rupture recovery can occur with the utilization of PAs. PAs embody the training, skills, and scope of practice to prevent and manage ACL injury; therefore, it becomes imperative to promote PA involvement in this injury. Proposed methods to achieve this objective include enhancing orthopaedic training in PA programs and integrating the work of national orthopaedic and PA organizations. More investigation is needed on this topic because having a comprehensive understanding of the potential roles of PAs in ACL care could have a profound, far-reaching impact on this increasingly prevalent injury.

Published: June 2021

Research and development of sigil-based teaching materials based on facts in yhe field, namely students rarely read textbooks in printed form because the display is less attractive, additive and addictive substances have not been delivered as a whole so thaht astudents miss lessons and lack insight. When in class students tend not to play attention because the learning used by teachers is often convensional and rarely uses media. Teaching materials are needed by students in learning activities that can be used anytime and anywhere so that learning activities can be efficient. The purpose of the study was to describe the results of validation and student responses to sigil-based teaching materials for junior high schools. This type of research is the research and development of R&D (Research and development). The development model in this study uses a model developed by Thiagarajan 4-D. The product that has been developed is then validated by 2 (two) lecturers from the Faculty of Tarbiyah and teacher Training consisting of material experts and media experts as well as one science teacher of SMP Plus Darus Shlolah as user expert. After being validated, the product is then field tested to determine student responses. The results of the materials expert assessment are 98.75%, 91.42% media expert and 92.30% user expert, all three have a high percentage so that the developed digital teaching material has the criteria of “very valid”. The small-scale trial results showed a percentage of 78.4% so they included the criteria of “interesting”. Large-scale trial results the percentage of results is 83.3% so it includes the criteria of “very interesting”.

This study aims to determine the level of understanding of science tadris students in semester 5A at IAIN Bengkulu in the biomolecule and metabolism course which is carried out in an online system. This research was conducted by giving online questionnaires/questionnaires to respondents. The type of questionnaire given is an open questionnaire, in which the respondent is free to fill in the answers according to their wishes. Based on the questionnaire, it was found that students had difficulty understanding biomolecule and Metaboism courses. The difficulty in understanding the material that has been provided online, which is deemed ineffective, this can have an effect on the low learning achievement of Tadris IPA 5A students at IAIN Bengkulu. For this reason, there is need for awareness from students to improve the learning process outside class hours, this aims to maximize student understanding of the materials and assignments given by the lecturer in order to maintain the stability of the value of each student.

The ultimate goal of sand control design in producing hydrocarbons is to obtain solids free at lowest cost per barrel. Therefore, predictable production and its associated cost is vital to achieve the best business value. Previously, the prediction of production from sand control well is cumbersome. This paper presents the novel method which using the field data to provide the insight of sand control and deliver an optimal design for the sanding propensity well.

Gravel pack sand control designs involves many parameters and is a tedious process for an engineer to interact with several dynamics parameters. This novel method started with field data collection from previous sand control operations. The datasets are prepared into the structured form, then reservoirs are sorted based on their similarities and finally the parameters are selected based on their significance. These parameters are mapped onto the productivity index using a variety of modeling types. The prediction result show that the productivity index can be modeled with high statistic measure (i.e. R-squared). Ultimately, Net Present Value (NPV) derived from anticipated reserves are known before pumping the gravel pack job. The continuous improvement of datasets can significantly help improve the sand control design.

In this study, the novel method is presented using field dataset to optimize the sand control design. The design process can be driven with the use of data and machine-learning algorithms. This emerging technology allows greater insight into the day-to-day operations. The continuous adoption of this technology is a key enabler of futuristic industrial 4.0. The data-driven process empowers the oil & gas industry to become more durable, robust and competitive.
Fit for Purpose Connection Design for Drilling Operations in Size Constrained Tubular
Authors: Plessis Guillaume , Muradov Andrei , Griffin Richard , Dugas Jeremy , Orlando Justin , Delcambre Devin
Published: June 2021

Drilling out or working within small sizes of casing and liners requires the use of a drill string with small outside diameter tool joints to fit inside the casing/liner bore and, at the same time, a large enough connection internal diameter to pump actuating balls inside the drill string when needed. These requirements significantly limit the available options that can be used.

Historically, a drill pipe double shoulder connection with a 3⅛-in. outside diameter (OD) has been used for such operations, as it allows for multiple makeups and breakouts before it needs to be repaired. This is a great improvement compared to using small tubing premium connections that are somewhat limited on the number of makeups. However, the geometry constraints are such that the thin material envelope leads to torsional weakness in the connection, resulting in a higher than expected recut rate as connections can be overtorqued downhole in operation.

A research and development (R&D) project was commissioned to improve the connection performance significantly to mitigate the downhole overtorque. Exploring the acceptable connection envelope limits allowed for a slightly reduced internal diameter (ID) when compared to the previously used connection. The team considered different thread designs and decided to use the one that would provide the highest torque. The design process was then followed to develop and qualify a well-balanced connection.

The design validation was performed at an engineering technology center in Houston, Texas, where samples were destructively tested to compare the actual capacity of the new connection against the calculated values. It was confirmed that the torsional strength of the new design meets and exceeds the theoretical value, an improvement of at least 85% over the previously used connection, and a first string was built. It was subsequently deployed in the field and the recut rate was monitored to establish that the objective of delivering a connection capable of higher torque was indeed met to resist the downhole overtorque.
