Published: July 2023

Both direct and indirect methods of exoplanet detection rely upon detailed knowledge of the potential host stars. Such stellar characterization allows for accurate extraction of planetary properties, as well as contributing to our overall understanding of exoplanetary system architecture. In this analysis, we examine the photometry of 264 known exoplanet host stars (harboring 337 planetary companions) that were observed during the Transiting Exoplanet Survey Satellite (TESS) Prime Mission. We identify periodic signatures in the lightcurves of these stars and make possible connections to stellar pulsations and their rotation periods, and compare the stellar variability to the published planetary orbital periods. From these comparisons, we quantify the effects of stellar variability on exoplanet detection, confirming that exoplanets detection is biased toward lower variability stars, but larger exoplanets dominate the population of exoplanets around variable stars. Exoplanet detection methods represented among these systems are distinct between stellar spectral types across the main sequence, though notable outliers exist. In addition, biases present in both the sourced data from TESS and the host star selection process, which strongly influences the representation of both stellar and planetary characteristics in the final populations. We also determine whether the host stars photometric variability affects or mimics the behavior or properties of the system’s planets. These results are discussed in the context of how the behavior of the host star is responsible for how we observe exoplanet characteristics, most notably their radii and atmospheric properties, and how the activity may alter our measurements or impact the evolution of planetary properties.

We present optical, radio, and X-ray observations of a rapidly evolving transient SN2019wxt (PS19hgw), discovered during the search for an electromagnetic counterpart to the gravitational-wave (GW) trigger S191213g. Although S191213g was not confirmed as a significant GW event in the off-line analysis of LIGO-Virgo data, SN2019wxt remained an interesting transient due to its peculiar nature. The optical/near-infrared (NIR) light curve of SN2019wxt displayed a double-peaked structure evolving rapidly in a manner analogous to currently known ultrastripped supernovae (USSNe) candidates. This double-peaked structure suggests the presence of an extended envelope around the progenitor, best modeled with two components: (i) early-time shock-cooling emission and (ii) late-time radioactive 56Ni decay. We constrain the ejecta mass of SN2019wxt at M
ej ≈ 0.20M
⊙, which indicates a significantly stripped progenitor that was possibly in a binary system. We also followed up SN2019wxt with long-term Chandra and Jansky Very Large Array observations spanning ∼260 days. We detected no definitive counterparts at the location of SN2019wxt in these long-term X-ray and radio observational campaigns. We establish the X-ray upper limit at 9.93 × 10−17 erg cm−2 s−1 and detect an excess radio emission from the region of SN2019wxt. However, there is little evidence for SN1993J- or GW170817-like variability of the radio flux over the course of our observations. A substantial host-galaxy contribution to the measured radio flux is likely. The discovery and early-time peak capture of SN2019wxt in optical/NIR observations during EMGW follow-up observations highlight the need for dedicated early, multiband photometric observations to identify USSNe.
RAM: Rapid Advection Algorithm on Arbitrary Meshes

Published: July 2023

The study of many astrophysical flows requires computational algorithms that can capture high Mach number flows, while resolving a large dynamic range in spatial and density scales. In this paper we present a novel method, RAM: Rapid Advection Algorithm on Arbitrary Meshes. RAM is a time-explicit method to solve the advection equation in problems with large bulk velocity on arbitrary computational grids. In comparison with standard upwind algorithms, RAM enables advection with larger time steps and lower truncation errors. Our method is based on the operator splitting technique and conservative interpolation. Depending on the bulk velocity and resolution, RAM can decrease the numerical cost of hydrodynamics by more than one order of magnitude. To quantify the truncation errors and speed-up with RAM, we perform one- and two-dimensional hydrodynamics tests. We find that the order of our method is given by the order of the conservative interpolation and that the effective speed-up is in agreement with the relative increment in time step. RAM will be especially useful for numerical studies of disk−satellite interaction, characterized by high bulk orbital velocities and nontrivial geometries. Our method dramatically lowers the computational cost of simulations that simultaneously resolve the global disk and potential well inside the Hill radius of the secondary companion.
Looking for Traces of Nonminimally Coupled Dark Matter in the X-COP Galaxy Clusters Sample
Authors: Gandolfi Giovanni , Haridasu Balakrishna S. , Liberati Stefano , Lapi Andrea
Published: July 2023

We look for possible evidence of a nonminimal coupling (NMC) between dark matter (DM) and gravity using data from the X-COP compilation of galaxy clusters. We consider a theoretically motivated NMC that may dynamically arise from the collective behavior of the coarse-grained DM field (e.g., via Bose–Einstein condensation) with averaging/coherence length L
NMC. In the Newtonian limit, the NMC modifies the Poisson equation by a term

L

NMC

proportional to the Laplacian of the DM density itself. We show that this term, when acting as a perturbation over the standard Navarro–Frenk–White (NFW) profile of cold DM particles, can yield DM halo density profiles capable of correctly fitting galaxy clusters’ pressure profiles with an accuracy comparable to and, in some cases, even better than the standard cold DM NFW profile. We also show that the observed relation between the NMC length scale and the virial mass found in Gandolfi et al. for late-type galaxies is consistent with the relation we find in the current work, suggesting that the previously determined power-law scaling law holds up to galaxy cluster mass scales.
Reoriented Memory of Galaxy Spins for the Early Universe
Authors: Moon Jun-Sung , Lee Jounghun
Published: July 2023

Galaxy spins are believed to retain the initially acquired tendency of being aligned with the intermediate principal axis of the linear tidal field, which disseminates the prospect of using them as a probe of early universe physics. This roseate prospect, however, is contingent upon the key assumption that the observable stellar spins of present galaxies measured at inner radii have the same alignment tendency toward the initial tidal field as their dark matter counterparts measured at virial limits. We test this assumption directly against a high-resolution hydrodynamical simulation by tracing the galaxy component particles back to the protogalactic stage. It is discovered that the galaxy stellar spins at z = 0 have strong but reoriented memory for the early universe, exhibiting a significant signal of cross-correlation with the major principal axis of the initial tidal field at z = 127. An analytic single-parameter model for this reorientation of the present galaxy stellar spins relative to the initial tidal field is devised and shown to be in good accord with the numerical results.
The Effects of Rotation, Metallicity, and Magnetic Field on the Islands of Failed Supernovae
Authors: Li 李 Lei 磊 , Zhu Chunhua , Guo Sufen , Liu Helei , Lü Guoliang
Published: July 2023

Failed supernovae (FSN) are a possible channel for the formation of heavy stellar-mass black holes (M
BH > ∼30 M
⊙). However, the effects of metallicity, rotation, and magnetic field on the islands of explodabilty of massive stars are not clear. Here, we simulate the stellar structure and evolution in the mass range between 6 and 55 M
⊙ with different initial rotational velocities, metallicities, and magnetic fields from zero-age main sequence (ZAMS) to pre-collapse. We find that the rapid rotating stars can remain lower 12C mass fraction at the time of C ignition, which allows the transition, from convective carbon burning to radiative burning, to occur at lower M
ZAMS than those from stars without rotation. However, the rapid rotation is unfavorable for FSN occurring but is conducive to long gamma-ray bursts (lGRBs) because it results in the specific angular momentum in the CO core being greater than the last stable orbit at core collapse. The increasing metallicity does not affect FSN islands, but high metallicity inhibits rotational mixing and is unfavorable for producing lGRBs. A magnetic field can constrain the mass-loss rate even for rapid rotating stars, resulting in higher mass at pre-collapse. The magnetic braking triggered by the magnetic field can reduce the rotation velocity for high-metallicity models, which decreases the specific angular momentum in the CO core and is favorable for FSN occurring. We suggest that the heavy-mass black holes detected by LIGO may originate from rapidly rotating massive stars with strong magnetic fields, rather than those with very low metallicity.
The Role of Microtubules in Heart Failure
Authors: Purwowiyoto Sidhi Laksono , Afiyani Nadia , Jusuf Axel , Kusharsamita Hillary
Published: July 2023

Heart failure (HF) is a complex pathological state in which cardiac performance fails to match perfusion demand, commonly preceded by an enlargement of the heart known as cardiac hypertrophy. Pathological changes in the microtubule network (MTN) organization have been shown to increase cellular stiffness and lead to contractile dysfunction of cardiomyocytes. In this narrative review, we are focusing on the role of the microtubule and also its mechanism in the heart, especially in HF. We conducted literature research for published articles carried out from 2012 to 2022. Microtubules are polymers that serve as structural elements with the shape of long, rigid tubes that are highly dynamic. The stiffness of the myocardium is largely influenced by the MTN. Through various methods, the MTN is remodeled during cardiac hypertrophy and HF. Targeting microtubules for the treatment of HF might become a new approach to improve the outcome. While colchicine inhibits various microtubule-dependent cellular in interphase cells and proliferation, it needs further study for the safety of the adjusted dosage. Manipulating detyrosination of microtubules might be useful for restoring the function of failing myocytes although there are still very limited data on this.
Revolutionizing Oman's energy network with an optimal mixture renewable energy source
Authors: Abdullah ALHinai Humaid , Mohd Ariffin Azrul , Osman Miszaina
Published: July 2023

The electricity demand has increased to 240% during the last decade in the Sultanate of Oman due to population growth and industrial expansion. Solar energy can act as an alternate source of energy production to meet the surge in demand for electric power. Also, the government has planned to derive 30% of the electricity from renewables by 2030. Moreover, agreements have been made to reduce greenhouse gas (GHG) emissions by decreasing 7% by 2030. The main objective of this paper is to design a grid-connected PV solar system based on the real-time data collected from the location called Nizwa, Oman using Hybrid Optimization of Multiple Electric Renewables (HOMER) software. The real-time data of average high and low temperature, solar radiation, estimated monthly average daily sunshine and peak hours of solar radiation of Nizwa has been collected from Meteorological Office Oman for January to December 2022. Nizwa recorded a temperature max of 43 ℃ during summer and 12 ℃ in January. Daily sun radiation in July averages between 5,500 and 6,000 Wh/m2, and the average sunshine is 9 hours per day at the selected project area (Nizwa). The collected data has been analyzed and designed using HOMER software. HOMER is used to model, optimize and analyze an integrated energy system that primarily utilizes renewable and non-conventional resources for both grid connected and autonomous systems. A 9-kW grid-connected PV solar panel has been designed and implemented in the proposed system. The proposed PV solar system worked perfectly and gave the results of an estimated number of hours of operation to be 4,362 hrs/year; the cost of energy per kilowatt is ＄ 0.044 and the annual energy saving cost of the hybrid system is ＄ 173.696. For the environmental feasibility of producing 14,765 kWh/yr, carbon dioxide emissions have decreased from 7,230,440 g to 4,396.001 g, with a difference of 7,226,043.9 g of carbon dioxide.
Optimal disclosure of information to privately informed agents
Authors: Candogan Ozan , Strack Philipp
Published: July 2023

We study information design with multiple privately informed agents who interact in a game. Each agent's utility is linear in a real‐valued state. We show that there always exists an optimal mechanism that is laminar partitional and bound its “complexity.” For each type profile, such a mechanism partitions the state space and recommends the same action profile within a partition element. Furthermore, the convex hulls of any two partition elements are such that either one contains the other or they have an empty intersection. We highlight the value of screening: the ratio of the optimal and the best payoff without screening can be equal to the number of types. Along the way, we shed light on the solutions to optimization problems over distributions subject to a mean‐preserving contraction constraint and additional side‐constraints, which might be of independent interest.
Utopie, Gefangenschaft, Verrat
Authors: Schmitz Walter
Published: July 2023

Zu jedem Exil gehört eine Vorgeschichte von Verfolgung, Gefangenschaft und Verrat. Die Besonderheit des deutsch-deutschen Literaturexils ergibt sich aus der Besonderheit der DDR als eine „partizipative“ Diktatur, die sich zudem als das „andere“, bessere Deutschland verstehen und präsentieren wollte. So fächert sich das Literaturexil vielfältig auf in Formen, Phasen, Lebenswege. Ebenso vielfältig sind die Formen der Traumatisierung, wie sie für die Autorschaft der Exilierten bestimmend bleibt. Poetologisch antwortet eine Utopie authentischen Schreibens ‚in der Wahrheit‘ auf das ‚Jahrhundert des Verrats‘ (Margret Boveri) – exemplarisch variiert in den Großromanen von Uwe Johnson, Horst Bienek und Guntram Vesper.
Ähnlichkeit als Strategie der Entdramatisierung
Authors: Colin Nicole
Published: July 2023

Im Mittelpunkt des Beitrags stehen die Erzählung Die Letzten: Aufzeichnungen aus Udo Posbichs Druckerei (2000) und der Roman Böse Schafe (2007) von Katja Lange-Müller. In ihrem ironischen, zuweilen sarkastischen Rückblick auf die untergegangene geteilte Stadt Berlin nimmt die Autorin in gelungener Weise eine subversive dritte Position ein, welche die in der Regel forcierten Gegensätze zwischen Ost und West deutlich relativiert. Ohne die real existierenden Probleme zu verharmlosen, ermöglicht die durch Ähnlichkeiten geprägte Darstellung der beiden Teile Berlins – insbesondere in der Beschreibung der verschiedenen Lebensstile auf beiden Seiten der Mauer – eine geradezu wohltuende Entideologisierung sowie Entdramatisierung der üblichen Ost-West-Dichotomien und eröffnet auf diese Weise mikrohistorische Perspektiven für ein potenzielles deutsch-deutsches Narrativ, das sich vor allem auf gemeinsame, aber oft vergessene Traditionen und Erfahrungen stützt.
Günter Kunerts „Platzwechsel“
Authors: Benoît Martine
Published: July 2023

Der Artikel versucht den gedanklichen Weg nachzuzeichnen, den Kunert ging, als er noch in der DDR lebte und dort als einer der wichtigsten Autoren seiner Generation galt, dann auch in der BRD von der Kritik und der literarischen Öffentlichkeit der Bundesrepublik mit größter Aufmerksamkeit wahrgenommen wurde, bis hin zum „Platzwechsel“, sprich Flucht der Flucht in die BRD und wie er dort seinen literarischen Platz fand und auf die Jahre in der DDR zurückblickte. Kunert, der das Wort Exil nicht für sich verwenden wollte, wurde nicht besonders herzlich in der BRD aufgenommen, blieb sein Leben lang gegenüber der DDR und ihrer Entwicklung sehr kritisch und begrüßte den Fall der Mauer und das Ende der DDR.
Roger Loewig : ni de l’Est ni de l’Ouest, de nulle part
Authors: Mortier Jean
Published: July 2023

Roger Loewig (1930-1997) ist Maler, Zeichner, Radierer und Poet. 1972 verlässt er die DDR, wo sowohl seine Gedankenwelt als auch sein tief durch die deutsche Schuld an den Gräueln der Vergangenheit und das Trauma der Teilung Deutschlands geprägtes Werk den Unmut der Behörden auf sich ziehen. Auch im Westen findet er seinen rechten Platz nicht. Die konsumorientierte Welt und die Herrschaft des Geldes stoßen ihn ab. Die neuen Formen in der Kunst bleiben ihm ebenfalls fremd. Die Verwirklichung der von ihm gehegten Hoffnung, endlich die ihm bisher versagte Anerkennung zu erlangen, lässt auf sich warten. Die Rezeption hebt die fantastische und surrealistische Dimension seiner Produktion hervor, während sich sein Werk eigentlich als engagiert und zutiefst humanistisch versteht. Loewig bleibt im Abseits des Kunstmarktes. Tiefe Wurzeln verbinden ihn nach wie vor mit seinem Ursprungsland. Richtung Osten bleibt sein Blick gewandt, Richtung Osten – nach Prag und Warschau – führen ihn seine Schritte immer wieder. Roger Loewig sollte der erste deutsche Zeichner sein, der im Museum von Auschwitz ausgestellt wurde.
En transit. Résonances d’exils
Authors: Farges Patrick
Published: July 2023

Kann man „das Unvergleichliche vergleichen“, d.h. Parallelen zwischen unterschiedlichen Exil- und Migrations-Paradigmen ziehen? Einerseits das Exil vor dem Nationalsozialismus nach 1933, andererseits das innerdeutsche Exil, also die Übersiedlung von Ost nach West nach 1945? In beiden Fällen stand die Dialektik zwischen Transit und Verankerung im Mittelpunkt eines Prozesses, der dem Exil einen (politischen, individuellen, künstlerischen) Sinn verlieh. Über den Verlust hinaus ist die Ent-Ortung produktiv, da sie Perspektiven der Dezentrierung/ Neuzentrierung, der Verankerung und Neuverankerung eröffnet, die ein anderes Sehen und Fühlen ermöglichen. Das Exil dringt somit tief in die Kunst und in das Leben ein. Es durchdringt die Materie des Werks, seine Struktur und sogar seine Färbung. In diesem Sinne erscheinen Kunst und Literatur als Mittel, tiefgreifende menschliche Mechanismen der Ent-Ortung zu verstehen.
NOITES IMAGINADAS EM TEMPOS PANDÊMICOS : ENTRE ESPAÇOS PRIVILEGIADOS, LUGARES VAZIOS E SOCIABILIDADE SUPERVISIONADA NA CIDADE DO RIO DE JANEIRO
Authors: Góis Marcos Paulo Ferreira de , Monteiro Leonardo José Iorio
Published: July 2023

Este artigo busca analisar as imagens da sociabilidade noturna no Rio de Janeiro, Brasil, durante a pandemia da covid-19. Apoiados por uma revisão da literatura sobre vida noturna e sociabilidade e pelos atos jurídicos relativos à disseminação e contenção do vírus, discutimos um conjunto de políticas e discursos públicos acerca da covid-19 e analisamos imagens jornalísticas que mostram cenários noturnos entre março de 2020 e o início de 2021. Concluiu-se que a vida social à noite foi um dos temas mais relevantes da imprensa para discutir medidas de contenção do vírus, e sua apresentação compõe um imaginário sobre usos de espaços e tipos de comportamento associados à noite na cidade que convivem com um conjunto de noções criadas sobre a noite ao longo dos anos. Essa estratégia discursiva tratou de cenários específicos de sociabilidade noturna e sua ordenação espacial como exemplos para amplificar essa reivindicação à cidade.
Transcending Boundaries
Authors: Gruber Sibylle
Published: July 2023

This chapter addresses the important role of moral respect, reciprocity, and dialogical interactions in order to create spaces that move beyond traditional heteronormative boundaries and engage with empathy across gender constructs. The author shows that awareness of heteronormative constructs is necessary to explore 21st-century solutions to such monumental issues as increased LGBTQI+ harassment, discrimination, bullying, and the erasure of LGBTQI+ rights in conjunction with economic, social, cultural, gender, civil, and political rights. The author utilizes a teacher research approach to highlight the successes of culturally responsive and sustaining teaching (CRST) practices with specific attention to intersectionality that respond to the concerns of LGBTQI+ youth as well as to students marginalized based on cultural, ethnic, racial, and economic backgrounds. The author concludes by arguing for teaching practices that draw on epistemological frameworks such as asymmetrical reciprocity and deep rhetorical listening to complicate and rethink normative stories about LGBTQI+ youth.
Promoting Unity in Diversity Through Integration of LGBTIQ+ Issues at the Borders of Classrooms and Sports Fields
Authors: Cools Wouter , Lecocq Gilles
Published: July 2023

Sport without Stereotypes! It is from this motto that this chapter proposes to focus on the way in which cultural spaces that welcome adolescents allow them to practice physical activity for competitive, fun, and/or educational purposes. This chapter has a regard in particular to “transgender and gender nonconforming adolescents” who need specific psychosocial support adapted to understanding the dynamics underlying the emergence of minority sexual orientations among adolescents. This will then be an opportunity to consider that the “person with minority sexual orientations” is the future of sporting humanity when a “with-them-apart” status is assumed by an adolescent and accepted by adults. This is what allows a stereotype to be lived fully and intensely within sports cultures: Be Stronger Together through our differences! Thus, between unity and diversity, the authors of this chapter are interested in the articulations to be valued between the I and the We, between sporting success and self-realization, between a “socially categorized sexuality” and a “singular sexuality assumed.”
Central Bank Digital Currency in India
Authors: Ozili Peterson K.
Published: July 2023

This chapter explores the benefits and issues surrounding the digital Rupee, also known as the eRupee or the central bank digital currency in India. The study found that Indian people who were interested in ‘cryptocurrency' information were also interested in ‘central bank digital currency' information. The study also showed that the introduction of CBDC has potential benefits such as reduced dependency on cash, higher seigniorage due to lower transaction costs, and reduced settlement risk. However, the India CBDC has associated risks that need to be carefully evaluated against the potential benefits. The introduction of a digital Rupee or CBDC in India will require legal and regulatory changes to make the phased CBDC implementation possible.

This research aims to design a human body temperature detection system based on the Internet of Things (IoT) and featuring the output with human voice. The implementation of the IoT concept using the MQTT Protocol. The stages in developing this system are needs analysis, design, develop, testing and evaluation. Principally, this system works as follows, once the temperature sensor detects a human temperature, the microcontroller will process this temperature data (1) convert the data into human voice and (2) sending (publish) the data to a web server in the internet. In this research uses Adafruit.com as Mqtt broker. Anyone subscribes to the feeds of the Adafruit will receive such temperature data automatically. To determine the output of the human temperature we must adjust with +3 from the original result of MLX90614 in the normal room temperature. By this adjustment we have the best of error average 0.96% and an average difference of result 0.35°C. It means, by adjustment +3 from the original result of the sensor will conform with the standards of IEC No. 13B-23 and the 13th revision of Melexis in 2019, where the maximum of error tolerance is 5% and the temperature difference is 0.5°C. For distance testing, the result is that the farther the object from the MLX90614 sensor will result the greater errors value and the object closer to the sensor, will result the smaller error. The average delay time to send data to the Adafruit Webserver and android application is 1.53 seconds.

The natural resources of the coastal sands of North Sulawesi are very potential and need to be explored and developed. Sand is composed of compounds based on the location of the sand along the coast. The potential of beach sand, namely Si (Silicon) can be a basic material such as SiC (Silicon Carbide) functional materials, semiconductors, and others. The first stage is sampling of white sand at several points and varying sand depths. Furthermore, the white sand is cleaned of impurities and iron sand. The second stage is sand preparation, sand identification and the third stage is silica extraction using the Alkali Fusion method using a high concentration base. Testing of elemental composition using XRF (X-ray Fluorescence), crystal structure using X-Ray Diffraction, and functional groups using Fourier Transform Infrared. The results of XRF analysis show that beach sand is composed of chemical compositions with a chemical component of CaO > 80%, the results of XRD analysis show that Silica (SiO2) compounds are in the form of quartz and show the Si-O functional group.

Authors: Khan M. A. , Pasha Mohammed Mahaboob , Arjun M. N. , Subramanian Narayanan
Published: July 2023

Background:

Venous thromboembolism (VTE) commonly presents as either deep-vein thrombosis (DVT) or pulmonary embolism (PE). Despite rapid advances in its diagnostic and therapeutic modalities, it still leads to significant morbidity and mortality.

Objectives:

Our study predominantly aims at studying the clinical profile, risk factors, and the clinical outcomes in VTE patients presenting to a single tertiary care center to rapidly detect the disease and use appropriate thrombo-prophylaxis.

Materials and Methods:

This was an prospective observational study involving 40 patients of confirmed cases of VTE who presented to this tertiary care hospital during a period from June 2017 to May 2019. Data collected included the age, sex, clinical presentation, risk factors, diagnostic modalities, and their clinical outcomes. Descriptive analysis was carried out by mean and standard deviation for quantitative variables; frequency and proportion for the categorical variables.

Results:

Among the study groups, 30 (74%) had DVT, 4 (11%) had PE, and 6 (15%) had both. Major risk factors detected included smoking history (44%), recent surgery (15%), malignancy (11%), history of immobility (10%), and past history of DVT (15%). The clinical presentation mainly included leg pain (62%) and leg swelling (87%). The outcomes were predominantly re-canalization (31%), recurrent DVT (21%), recurrent PE (1%), chronic DVT (27%), chronic venous insufficiency (36%), chronic venous ulcer (7%), pulmonary hypertension (16%), and death (5%). In our study population, the most common pro-thrombotic state was found to be hyperhomocysteinemia.

Conclusions:

In our study of VTE patients, we have highlighted the possible risk factors, clinical presentation, and clinical outcomes to identify the disease early and help us initiate appropriate thromboprophylaxis to reduce morbidity.

Aim:

The study explores the emergence of COVID-19 pandemic fatigue among well-educated Egyptians measured in terms of their level of adherence toward COVID-19 protective measures along 20 months since the beginning of the pandemic.

Setting and Design:

A cross-sectional study was conducted in October 2021, using an online questionnaire for well-educated Egyptians in different governorates.

Results:

A total of 888 participants completed the questionnaire, their mean age was 39 ± 7.2 years and 60% of them were females. There was a strong association between the presence of either behavioral risk factors or chronic conditions and % of infection. The main sources of COVID-19 information were social media, followed by the Egyptian Ministry of health and population and WHO websites. A pandemic fatigue was observed after nearly 7 to 10 months from the pandemic emergence. The participant’s age, previous COVID-19 infection, and occupation status were significant predictors for adherence to COVID-19 protective measures. The participants claimed that difficulty in remaining at home, feeling uncomfortable with face masks, the high cost of protective supplies, absence of governmental enforcement, and forgetfulness are the most perceptive barriers hindering their adherence to COVID-19 protective measures. They suggested some strategies for better adherence and reduced pandemic fatigue that includes: the implementation of governmental enforcement measures, including penalties for nonwearing masks, educational health programs, and availability of free protective supplies at the workplace.

Conclusions:

Pandemic fatigue was observed after 7 to 10 months from the pandemic emergence even though the high education level of the participants.

Background

Following coronary artery bypass graft (CABG), the main causes of postoperative morbidity and mortality are postoperative pulmonary complications, respiratory dysfunction, and arterial hypoxemia.

Aim

To evaluate the effect of postoperative incentive spirometry (IS) on dyspnea severity among patients undergoing CABG.

Research hypothesis

H1: there is a statistically significant improvement in dyspnea severity among patients undergoing CABG after using IS when compared with before use.

Design

A quasi-experimental (one group pretest–posttest) design was used in the current study.

Setting

This study was conducted at selected cardiothoracic care units and cardiothoracic ward affiliated to Cairo University Hospitals.

Sample

A convenient sample of 49 adult patients undergoing CABG was included.

Tools

Three tools were used to collect data: first, demographic characteristics and health relevant data; second, chest auscultation; and third, dyspnea severity score.

Results

There were statistically significant improvements found in the dyspnea severity score on first day, second day, and third day after using IS compared with before using spirometry among the patients.

Moreover, there was significant improvement in chest auscultation before and after using spirometry. Half of the patients (53.1%) revealed regaining of normal breath sounds on the third day after using IS versus before using spirometry, where only 28.6% had normal breath sounds on the third day.

Conclusion

It can be concluded that postoperative IS decreased dyspnea severity and improved respiratory function among patients undergoing CABG.

Recommendation

Future trials may be carried out with adequate research grants with postoperative IS after major surgery and other respiratory diseases to improve dyspnea severity without medication.

Authors: Katragadda Bharat Chandra , Kumar S. Satheesh , Suresh Anoop
Published: July 2023

Background:

Most patients requiring total knee arthroplasty (TKA) have bilateral symptoms and need surgery on both knees. The decision to adopt a simultaneous versus a staged bilateral TKA (BTKA) remains a matter of much debate. Our study tries to alleviate the surgeon and patient concerns regarding three main parameters of TKA – costs, complications, and clinical outcomes.

Materials and Methods:

In this retrospective study, two propensity-matched cohorts of patients who underwent simultaneous BTKA (n = 350) and unilateral TKA (UTKA, n = 350) were created. The complications profile, costs involved, and functional outcomes were compared between the two groups.

Results:

There was no significant difference in the mortality rate and major and minor complications between the two groups. A pulmonary embolism (PE) rate of 1.7% in BTKA patients was higher than 0.3% after UTKA (P = 0.07). A significant postoperative hemoglobin drop was noted after BTKA, but there was no significant difference in transfusion requirement between the cohorts (2.5% vs. 1.3%, P = 0.3). BTKA on average reduced the hospital stay by 2.7 days, rehabilitation requirement by 3.4 days, and the overall costs by 20% when compared to undergoing UTKA twice in a staged BTKA procedure. Pain scores and function scores were similar at the final follow-up.

Conclusions:

In our study, BTKA was associated with similar functional outcomes and safety profiles compared to UTKA. We suggest the use of simultaneous BTKA in bilateral symptomatic patients since the overall costs could be reduced by 20% compared to staged BTKA.

Introduction:

Anterior cruciate ligament (ACL) is the most common ligament injured in the knee and its major portion attributed to contact sports. This study aims to reveal the correlation between clinical examination, magnetic resonance imaging (MRI) evaluation, and arthroscopic findings in ACL injury with the consideration of arthroscopic findings as the gold standard among them.

Materials and Methods:

A prospective double blinded study conducted in 161 patients attended sports injury clinic from September 2020 to September 2022. Patient selection done with well defined inclusion and exclusion criteria. All selected patients were underwent clinical examination, MRI evaluation and arthroscopic procedure.

Results:

The sensitivity of clinical examination and MRI evaluation for ACL injury was the same (94.9%), while specificity were 72.1 and 79.1%, respectively. Positive and negative predictive value of clinical examination was 90.3% and 83.8%, were as for MRI evaluation, it was 92.6% and 85.0%. The accuracy of MRI evaluation and clinical examination were 90.7% and 88.8%, respectively.

Conclusion:

A methodically performed clinical examination is equivocal to MRI evaluation in isolated ACL injury and MRI evaluation can be useful to clarify the diagnosis in doubtful clinical scenarios.

Published: July 2023

Globally, the proportion of reverse total shoulder arthroplasty (RTSA) is on the rise compared to the anatomic total should replacement and hemiarthroplasty. Historically performed as a salvage surgery for cuff tear arthropathy, the indications for RTSA have now expanded over the years owing to an evolution in implant designs and the application of biomechanics in the shoulder joint. The indications for reverse polarity prosthesis have expanded from the earlier cuff tear arthropathy to included a wide range of noncuff related indications as well. The goal of this brief overview is to walk readers through the growing list of RTSA indications. The indications for RTSA are ever increasing due to its peculiar design, biomechanical advantages, and relatively good functional outcome. Off-label indications are expanding and the avenue is yet to be completely explored.
