APOPHATHICS OF THE TEXT. TATYANA’S DREAM IN A.S. PUSHKIN’S NOVEL “EUGENE ONEGIN”: CULTURAL COMMENTARY
Authors:   Peoples' Friendship University of Russia, Dudareva M.A.
Published: March 2022

The object of the article is apophatics as a phenomenon of artistic culture. The subject is the national topic in A.S. Pushkin’s works. The material for the article is the novel “Eugene Onegin”. The fifth chapter of the novel, namely Tatyana’s dream, is in the center of the hermeneutic reconstruction. Much attention is paid to the Russian folklore tradition in the novel, which is expressed both explicitly and implicitly. The research methodology is reduced to a holistic ontohermeneutical analysis aimed at highlighting the folkloric, ethnographic paradigm of this literary text, which allows addressing the issues of the creative process itself ontologically, digging into the understanding of the phenomenon of Pushkin’s “magic crystal”. Much attention is paid to the dream as a borderline state, which is equated with death. Parallels are drawn with the Russian fairy tale and folkloric account. Tatyana has semiotic thinking, and this must be taken into account by a researcher analyzing the oneiric space of "Eugene Onegin". The research results are to identify the cultural potential of the work for further study of the national topic, national existence and otherness, apophatics as a phenomenon of Russian culture associated with the phenomenon of death. The research results can also be used in teaching courses on Russian literature of the 19th century, cultural studies, philosophy.
Subarachnoid hemorrhage: management considerations for COVID-19
Authors: Panther Eric J. , Lucke-Wold Brandon
Published: March 2022

Subarachnoid hemorrhage (SAH) has deleterious outcomes for patients, and during the hospital stay, patients are susceptible to vasospasm and delayed cerebral ischemia. Coronavirus disease 2019 (COVID-19) has been shown to worsen hypertension through angiotensin-converting enzyme 2 (ACE2) activity, therefore, predisposing to aneurysm rupture. The classic renin-angiotensin pathway activation also predisposes to vasospasm and subsequent delayed cerebral ischemia. Matrix metalloproteinase 9 upregulation can lead to an inflammatory surge, which worsens outcomes for patients. SAH patients with COVID-19 are more susceptible to ventilator-associated pneumonia, reversible cerebral vasoconstriction syndrome, and respiratory distress. Emerging treatments are warranted to target key components of the anti-inflammatory cascade. The aim of this review is to explore how the COVID-19 virus and the intensive care unit (ICU) treatment of severe COVID can contribute to SAH.

There are several ways that can be done to prevent the transmission of Covid-19, one of which is by spraying disinfectant in the surrounding environment and objects that are at risk of transmitting the virus. Making your own disinfectant at home can actually be done using ingredients that are household cleaning products. However, many people from Panca Jaya village, Muara Kaman sub-district, Kutai Kartanegara district, still don't know how to make a disinfectant, even if they know they generally just mix chemicals with water without knowing the content, properties and dosages that will be used to make the disinfectant. Seeing this in the field, it is necessary to have educational activities for the community regarding the manufacture of disinfectants. The purpose of this community service is to provide knowledge and understanding to the residents of Panca Jaya village about how to make disinfectants with home cleaning products in their respective homes. The method used in this counseling was to provide information via LCD and give out pamphlets to participants, demonstrate to make disinfectant, then continue spraying disinfectant in the surrounding environment. It is hoped that this activity can be applied in their daily life as a form of prevention and transmission of Covid-19.

Rambu-Rambu Village is one of the villages in Laeya District, South Konawe Regency. Rambu-Rambu Village has potential human resources, potential for agricultural and plantation products that can support entrepreneurial development. The problem faced by the community, especially the Family Welfare Empowerment Group (FWE)) is that they do not yet have the knowledge and understanding of entrepreneurship because they have never received entrepreneurship counseling from the government and universities. To overcome this problem, it is important to conduct counseling through the Institute for Research and Community Service (IRCS). The purpose of entrepreneurship counseling is to convey information to the FWE group so that they have knowledge, understanding and increase the participants' insight on how to do entrepreneurship. The method of implementing the extension is through the stages of observation and site survey, coordinating with the village government, preparing the location for the extension event, and providing tools or facilities and infrastructure, then carrying out counseling through lectures and questions and answers. Entrepreneurship counseling was held at the Rambu-Rambu Village Hall with a total of 42 participants. The results of the extension activities showed that the extension materials delivered by the extension team were very useful for the FWE group because it could provide motivation, could increase knowledge and understanding of entrepreneurship and could encourage the FWE group to be more creative and innovative in taking micro and small business opportunities. From the results of the question and answer, it was also revealed that after completing the entrepreneurship counseling activities, it is better to continue the beginner entrepreneur training activities for the practice of making micro and small business products.

Meaning above (and in) the head: Combinatorial visual morphology from comics and emoji
Authors: Cohn Neil , Foulsham Tom
Published: March 2022

Compositionality is a primary feature of language, but graphics can also create combinatorial meaning, like with items above faces (e.g., lightbulbs to mean inspiration). We posit that these “upfixes” (i.e., upwards affixes) involve a productive schema enabling both stored and novel face–upfix dyads. In two experiments, participants viewed either conventional (e.g., lightbulb) or unconventional (e.g., clover-leaves) upfixes with faces which either matched (e.g., lightbulb/smile) or mismatched (e.g., lightbulb/frown). In Experiment 1, matching dyads sponsored higher comprehensibility ratings and faster response times, modulated by conventionality. In Experiment 2, event-related brain potentials (ERPs) revealed conventional upfixes, regardless of matching, evoked larger N250s, indicating perceptual expertise, but mismatching and unconventional dyads elicited larger semantic processing costs (N400) than conventional-matching dyads. Yet mismatches evoked a late negativity, suggesting congruent novel dyads remained construable compared with violations. These results support that combinatorial graphics involve a constrained productive schema, similar to the lexicon of language.

DNA molecule is found in every cell in a living organism and function as an instruction manual for growth, development, as well as any other processes that happen. As the cell divide, it needs to copy its DNA. During the copying, an error can occur, which can lead to a disease. However, there are different error repair mechanisms that are searching for an error, and repairing it. This study focused on 2 proteins involved in DNA repair mechanism, RPA32B and RPA2 from Arabidopsis thaliana. Throughout multiple in silico approached,  multiple sequence alignment, phylogenetic tree construction, 3D visualisation, combination and interaction, we confirmed that the  RPA2 and RPA 32b are involved in DNA replication, meiotic recombination and DNA repair mechanism.

The Comparison of the Effectiveness of Respiratory Physiotherapy Plus Myofascial Release Therapy Versus Respiratory Physiotherapy Alone on Cardiorespiratory Parameters in Patients With COVID-19
Authors: Fereydounnia, PhD, PT Sara , Shadmehr, PhD, PT Azadeh , Tahmasbi, MSc, PT Alireza , Salehi, MSc, SPT Raha Shams
Published: March 2022

Background: Respiratory involvement is a common consequence of COVID-19; changes in cardiorespiratory parameters of these patients during respiratory rehabilitation program are very important. Previous studies showed that myofascial release therapy (MFRT) could affect the respiratory muscle and adjunct fascia.
Purpose: The aim of this study was to evaluate the effects of MFRT techniques and respiratory physiotherapy, in comparison with respiratory physiotherapy alone, on improving cardiorespiratory parameter in patients with COVID-19.
Setting: A hospital affiliated to Tehran University of Medical Sciences in Tehran, Iran, from February to July 2021.
Participants: Fifty patients with COVID-19 participated in this study.
Research Design: A single-blind, ran-domized control design.
Intervention: The patients with COVID-19 randomly assigned to an intervention group who received respiratory physiotherapy combined with MFRT or a control group receiving respiratory physiotherapy alone.
Main Outcome Measure(s): Heart rate, systolic and diastolic blood pressure, respiration rate, oxygen saturation, chest expansion, and ease of breathing were assessed at baseline and after the first and third session of treatment. Dyspnea and fatigue perception and 6-minute walking were assessed at baseline and at the end of treatment. Patient’s thoughts about the treatment were examined through the 4-point Likert scale.
Results: The ANOVAs found significant time effect for ease of breathing, dyspnea perception (F = 32.33, p < .01 and F = 11.72, p < .01, respectively). Also significant time by group interaction was found for chest expansion at xiphoid level (F = 4.02, p = .02).
Conclusions: The present study provided evidence that both programs could result in improving ease of breathing and dyspnea perception, although the inclusion of MFR techniques into a respiratory physiotherapy program did not result in better outcomes in cardiorespiratory function of patients with COVID-19.

Authors: Geoffroy-Legeay, BTSM, RMT Hélène
Published: March 2022

Objectives: This case report aimed to explore the process and outcomes of a seven-week massage therapy treatment on post-surgical intervention to reduce humeral shaft fracture.
Participant: An active 9-year-old girl who recently moved in the region and who underwent two surgeries following a humeral fracture with displacement after a fall at school.
Intervention: The treatment used various techniques such as manual lymphatic drainage (MLD), myofascial release (MFR), therapeutic massage, and neuromuscular techniques (NMT) in conjunction with the physiotherapist rehabilitation programme to help the client recover both physically and emotionally from the trauma. Evaluation of the outcome measures (OM) took place throughout the study and after the four-week interim that followed the interven-tion period.
Results: The massage th erapy intervention indicated improvement regarding range of motion (ROM) and muscular strength. The clients’ progress using the Patient-Specific Functional Scale (PSFS) indicated a gradual evolution to reach almost a 95% gain, and the Upper Extremity Function Index (UEFI) also showed improvement in everyday activities with a 21.5% positive change. The Child Outcome Rating Scale (CORS) and subsequent Child Session Rating Scale (CSRS) monitored therapeutic progress and indicated improvement on biopsychosocial (BPS) aspects throughout the treatment.
Conclusion: The client felt strong and more confident after each massage in-tervention. A combination of techniques and the child’s empowerment positively affected the client’s overall wellness and confidence to return to activities.
The Experiences of Touch Therapies in Symptom Management of Rural and Regional Cancer Patients in Australia
Authors: Cadet, PhD Tamara , Davis, PhD Cindy , Wilson, MHealth, BCouns, RN Patricia , Elks, RN Jacinta
Published: March 2022

Introduction: Cancer patients are increasingly combining touch therapies (e.g., remedial massage, lymphatic massage, and/or reflexology) with conventional treatments to deal with the impact of their cancer and treatments on their physical and mental well-being. To understand the impact of integrative oncology services on cancer patients, it is essential to explore the impact that various types of integrative oncology services have on cancer patients.
Aims: This paper presents cancer patients’ experiences with touch therapies in a community-based cancer support center and to identify opportunities for better access to these practices and service provision in Australia.
Methods: A random selection of cancer patients (n=36) receiving touch therapies at a rural/regional community cancer center completed mixed-methods mail surveys regarding the use of touch therapies, their satisfaction, and the impact on pain, fatigue, nausea and overall well-being.
Results: Findings indicated that these services helped manage both physical and emotional symptoms. Of the participants experiencing pain and fatigue, findings revealed that touch therapies assisted with pain in 90% of participants and with fatigue in 70%.
Conclusion: Given the increased and continued use of touch therapies by individuals with cancer, cancer centers should consider establishing touch therapy services or provide referrals to touch therapy services that can assist with symptom management and improve quality care. By more clearly understanding the benefits of the different types of integrative oncology interventions, patients with cancer receive more tailored and effective interventions throughout of their cancer journey.
A STUDY ON THE IMPACT OF SUSTAINABLE MANAGEMENT ON EARNINGS PERSISTENCE AND MARKET PRICING: EVIDENCE FROM KOREA
Authors: Ma Hee Young , Yoo Ji Yeon
Published: March 2022

This study examines the implications of sustainable management for the persistence of earnings and earnings components. This study also analyzes whether sustainable management influences investors’ assessments of earnings persistence. According to previous studies, sustainable management activities ultimately have a positive effect on corporate financial performance and corporate value by satisfying the desires of not only shareholders, but also various actors concerned with social contributions and reduced information asymmetry. In addition, the transparency of financial reporting increases as earnings management decreases due to ethical management. So this study predicts that excellent sustainable management activities will improve earnings persistence and investors use as a signal to correctly price the persistence of earnings. This research uses the ESG ratings as a proxy for sustainable management and sample size is 3,247 in Korea securities market. The empirical results show that there is a significant positive relationship between higher ESG grades and earnings and earnings components. And by the method of Mishkin (1983), investors correctly price the persistence of earnings and earnings components based upon sustainable management activities. The results in this study helps to improve our understanding of the impact of sustainable management for earnings quality and investors’ evaluation of earnings quality.

Modeling Ion Beams, Kinetic Instabilities, and Waves Observed by the Parker Solar Probe near Perihelia
Authors: Ofman Leon , Boardsen Scott A , Jian Lan K , Verniero Jaye L , Larson Davin
Published: March 2022

Recent in situ observations from the Parker Solar Probe (PSP) mission in the inner heliosphere near perihelia show evidence of ion beams, temperature anisotropies, and kinetic wave activity, which are likely associated with kinetic heating and acceleration processes of the solar wind. In particular, the proton beams were detected by PSP/Solar Probe Analyzers-Ion (SPAN-I) and related magnetic fluctuation spectra associated with ion-scale waves were observed by the FIELDS instrument. We present the ion velocity distribution functions (VDFs) from SPAN-I and the results of 2.5D and 3D hybrid-particle-in-cell models of proton and α particle super-Alfvénic beams that drive ion kinetic instabilities and waves in the inner heliospheric solar wind. We model the evolution of the ion VDFs with beams, and obtain the ion relative drifts speeds, and ion temperature anisotropies for solar wind conditions near PSP perihelia. We calculate the partition of energies between the particles (ions) along and perpendicular and parallel to the magnetic field, as well as the evolution of magnetic energy, and compare to observationally deduced values. We conclude that the ion beam driven kinetic instabilities in the solar wind plasma near perihelia are important components in the cascade of energy from fluid to kinetic scales, an important component in the solar wind plasma heating process.

distributions measured in situ by the Mars Atmosphere and Volatiles EvolutioN (MAVEN) orbiter, we derive semiempirical average energetic neutral atom (ENA) distributions near Mars. Differential fluxes of H-ENAs and O-ENAs are estimated by line-integrating ENA production and loss rates in the average phase-space ion distributions. By repeating the procedure for a systematic series of vantage points, we produce synthetic ENA observations for virtual circular orbits with radii twice that of Mars, revealing the angular dependence of the observer’s position. Accounting for known ENA production and loss terms, we find that H+ in the upstream solar wind yields total antisunward H-ENA fluxes of ∼3 × 105 cm−2 s−1. The dayside magnetosheath produces H-ENA angular-differential fluxes of up to 3 × 105 cm−2 s−1 sr−1, while the magnetosheath flanks populate the planet’s nightside with H-ENA fluxes in the range of 104–105 cm−2 s−1 sr−1. The O-ENA environment is dominated by a near-isotropic ∼105 cm−2 s−1 sr−1 relatively low-energy (tens of eV) population originating in the top-side ionosphere, particularly on the dayside. Lower fluxes (103–104 cm−2 s−1 sr−1) of energetic O-ENAs (≳100 eV) are mainly found on the nightside and above the electric polar regions of the induced magnetosphere. Asymmetries in the ENA flow are largely limited to the energetic O-ENA populations, while the H-ENA distribution is mostly symmetric around the Sun‒Mars line. We discuss how synthetic ENA observations can provide insight into the near-Mars space environment, including the planet’s plasma environment and exosphere.
Properties of Type Ibn Supernovae: Implications for the Progenitor Evolution and the Origin of a Population of Rapid Transients
Authors: Maeda Keiichi , Moriya Takashi J.
Published: March 2022

Type Ibn supernovae (SNe Ibn) show signatures of strong interaction between the SN ejecta and hydrogen-poor circumstellar matter (CSM). Deriving the ejecta and CSM properties of SNe Ibn provides a great opportunity to study the final evolution of massive stars. In the present work, we present a light-curve (LC) model for the ejecta–CSM interaction, taking into account the processes in which the high-energy photons originally created at the forward and reverse shocks are converted to the observed emission in the optical. The model is applied to a sample of SNe Ibn and “SN Ibn” rapidly evolving transients. We show that the characteristic post-peak behavior commonly seen in the SN Ibn LCs, where a slow decay is followed by a rapid decay, is naturally explained by the transition of the forward-shock property from cooling to adiabatic regime without introducing a change in the CSM density distribution. The (commonly found) slope in the rapid-decay phase indicates a steep CSM density gradient (ρ
CSM ∝ r
−3), inferring a rapid increase in the mass-loss rate toward the SN as a generic property of the SN Ibn progenitors. From the derived ejecta and CSM properties, we argue that massive Wolf–Rayet stars with an initial mass of ≳18 M
⊙ can be a potential class of the progenitors. The present work also indicates the existence of a currently missing population of UV-bright rapid transients for which the final mass-loss rate is lower than the optical SNe Ibn, which can be efficiently probed by future UV missions.

The relative distribution of molecular gas and star formation in galaxies gives insight into the physical processes and timescales of the cycle between gas and stars. In this work, we track the relative spatial configuration of CO and Hα emission at high resolution in each of our galaxy targets and use these measurements to quantify the distributions of regions in different evolutionary stages of star formation: from molecular gas without star formation traced by Hα to star-forming gas, and to H ii regions. The large sample, drawn from the Physics at High Angular resolution in Nearby GalaxieS ALMA and narrowband Hα (PHANGS-ALMA and PHANGS-Hα) surveys, spans a wide range of stellar masses and morphological types, allowing us to investigate the dependencies of the gas‒star formation cycle on global galaxy properties. At a resolution of 150 pc, the incidence of regions in different stages shows a dependence on stellar mass and Hubble type of galaxies over the radial range probed. Massive and/or earlier-type galaxies in our sample exhibit a significant reservoir of molecular gas without star formation traced by Hα, while lower-mass galaxies harbor substantial H ii regions that may have dispersed their birth clouds or formed from low-mass, more isolated clouds. Galactic structures add a further layer of complexity to the relative distribution of CO and Hα emission. Trends between galaxy properties and distributions of gas traced by CO and Hα are visible only when the observed spatial scale is ≪500 pc, reflecting the critical resolution requirement to distinguish stages of the star formation process.
Toward a More Complete Optical Census of Active Galactic Nuclei via Spatially Resolved Spectroscopy

Published: March 2022

While emission line flux ratio diagnostics are the most common technique for identifying active galactic nuclei (AGNs) in optical spectra, applying this approach to single-fiber spectra of galaxies can omit entire subpopulations of AGNs. Here, we use spatially resolved spectroscopy from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey to construct a sample of 10 galaxies where Baldwin–Philips–Terlevich line flux ratio diagnostics classify each galaxy’s central 3″ spectrum as LINER or star-forming, while >10% of the spaxels in the galaxy’s MaNGA footprint are classified as Seyfert. We obtain Chandra observations of these 10 galaxies with off-nuclear Seyfert regions to determine whether AGNs are actually present in them. Our main result is that 7–10 (depending on strictness of criteria) of the galaxies host one or more X-ray AGNs, even though none of them were classified as AGNs based on their single-fiber optical spectra. We find that these AGNs were not identified in the single-fiber spectra because they are AGNs in the nuclei of companion galaxies, low-luminosity AGNs, dust-obscured AGNs, and/or flickering AGNs. In summary, we find that off-nuclear AGN signatures may increase the number of known AGNs by a factor of two over what conventional single nuclear fiber spectra identify. Our results show that spatially resolved spectroscopy can be leveraged to reveal a more complete census of AGNs that are traditionally missed by single-fiber spectra.

We present 0.″035 resolution (∼200 pc) imaging of the 158 μm [C ii] line and the underlying dust continuum of the z = 6.9 quasar J234833.34–305410.0. The 18 hour Atacama Large Millimeter/submillimeter Array observations reveal extremely compact emission (diameter ∼1 kpc) that is consistent with a simple, almost face-on, rotation–supported disk with a significant velocity dispersion of ∼160 km s−1. The gas mass in just the central 200 pc is ∼4 × 109
M
⊙, about a factor of two higher than that of the central supermassive black hole. Consequently we do not resolve the black hole’s sphere of influence, and find no kinematic signature of the central supermassive black hole. Kinematic modeling of the [C ii] line shows that the dynamical mass at large radii is consistent with the gas mass, leaving little room for a significant mass contribution by stars and/or dark matter. The Toomre–Q parameter is less than unity throughout the disk, and thus is conducive to star formation, consistent with the high-infrared luminosity of the system. The dust in the central region is optically thick, at a temperature >132 K. Using standard scaling relations of dust heating by star formation, this implies an unprecedented high star formation rate density of >104
M
⊙ yr−1 kpc−2. Such a high number can still be explained with the Eddington limit for star formation under certain assumptions, but could also imply that the central supermassive black hole contributes to the heating of the dust in the central 200 pc.
Testing the Cosmological Principle: Astrometric Limits on Systemic Motion of Quasars at Different Cosmological Epochs
Authors: Makarov Valeri V. , Secrest Nathan J.
Published: March 2022

A sample of 60,410 bona fide optical quasars with astrometric proper motions in Gaia Early Data Release 3 and spectroscopic redshifts above 0.5 in an oval 8400 square degree area of the sky is constructed. Using orthogonal Zernike functions of polar coordinates, the proper motion fields are fitted in a weighted least-squares adjustment of the entire sample and of six equal bins of sorted redshifts. The overall fit with 37 Zernike functions reveals a statistically significant pattern, which is likely to be of instrumental origin. The main feature of this pattern is a chain of peaks and dips mostly in the R.A. component with an amplitude of 25 μas yr−1. This field is subtracted from each of the six analogous fits for quasars grouped by redshifts covering the range 0.5 through 7.03, with median values of 0.72, 1.00, 1.25, 1.52, 1.83, 2.34. The resulting residual patterns are noisier, with formal uncertainties up to 8 μas yr−1 in the central part of the area. We detect a single high-confidence Zernike term for the R.A. proper motion components of quasars with redshifts around 1.52 representing a general gradient of 30 μas yr−1 over 150° on the sky. We do not find any small- or medium-scale systemic variations of the residual proper motion field as functions of redshift above the 2.5σ significance level.

Published: March 2022

Introduction: Limb salvage in children with primary malignant bone tumors in lower extremity is challenging, with considerations such as shortening, bone and joint remodeling and high functional demands of active children. We adopted a biological approach by preserving the patient native joint, with bony defects bridged by autologous tibial biological grafts.Presentation of Case: A 16-year-old female with pain in the left lower leg and was diagnosed with a tibial distal osteosarcoma. The patient was perform preoperative chemotherapy and had a good result. This was assessed clinically by a decrease in the size of the swelling and pain from the tumor, and radiological. Then she underwent wide excision surgery, we decided to perform biological reconstruction with pasteurized technic, and evaluation after 3 month (union, early weight bearing and rehabilitation).Discussion: We found that biological reconstruction using pasteurized technic with autologous tibial biological grafts is a viable option in children with high grade osteosarcoma in lower extremity. It provides immediate stability, allows early weight bearing and early rehabilitation. Time to full weight bearing is shorter than prosthetic replacement. Use of autologous tibial biological grafts has lower cost, no rejection because the patient’s own tissue is used, exact anatomical matching and no donor morbidity.Keyword: biological bonegraft, pasteurized, osteosarcoma.

Authors: Hamila Mohamed , Hussein Khaled , Ismail Mohamed Fatehy , Kamal Ahmed
Published: March 2022

BACKGROUND: Head trauma and traumatic brain injury (TBI) are major causes of death and disability worldwide. TBI is associated with a variety of electrocardiographic (ECG) changes.

AIM: We aimed to evaluate the prevalence of ECG changes in TBI.

METHODS: Participants with TBI were included in the study, while participants with chest trauma or cardiovascular diseases were excluded from the study. A consecutive sample of 50 participants (mean age 37.8 ± 14.85 years, 80% males) was selected and referred for 12 lead ECG on admission, 24 h, and 72 h after admission.

RESULTS: The prevalence of sinus bradycardia versus sinus tachycardia, short PR interval, ST segment elevation, and inverted T wave in the study population was 18% versus 38%, 26%, 2%, and 16% in ECG on admission, 5% versus 22%, 14%, 0%, and 10% in ECG 24 h after admission, 5% versus 8%, 4%, 0%, and 8% in ECG 72 h after admission, respectively. Serial ECG was significantly associated with changes in heart rate (χ² [1] = 17.337, p = 0.002) and short PR interval (χ² [1] = 9.695, p = 0.008), respectively. There was a significant association between ECG changes and brain edema (χ² [1] = 4.131, p = 0.042), intracerebral hemorrhage (χ² [1] = 4.539, p = 0.033), and subarachnoid hemorrhage groups (χ² [1] = 5.889, p = 0.015), respectively.

CONCLUSIONS: ECG changes are prevalent in non-cardiac TBI patients. The significant association of serial ECG with changes in heart rate and short PR interval and the significant association of ECG changes with brain edema, intracerebral hemorrhage, and subarachnoid hemorrhage highlights the potential role of serial ECG as a screening tool for cardiac dysfunction in patients with TBI.

Published: March 2022

Background: Efforts to prevent and control DHF in Palu City are still inadequate. The lack of community participation in the implementation of 3M causes the density of Aedes aegypti larvae to be high.
Objective: To analyze the knowledge, attitudes and behavior of larva monitoring interpreters before and after being given health education in reducing dengue cases.
Methods: This type of research is a quasi-experimental, with one group pre and posttest design. Carried out in Palu City, Central Sulawesi Province and Pasang Kayu Regency, West Sulawesi Province. The sample size is 98 Jumantik cadres. The interview study instrument used a set of previously validated and tested questionnaires. Informed consent was taken from all respondents and confidentiality was guaranteed throughout the study. Data were analyzed using SPSS with Paired T-test dependent  
Results: Knowledge about ways to prevent DHF increased the highest from the pre-test (20.10) post-test (51.77) which means that it increased by 32.3% p = 0.000, the smallest increase in knowledge about the spread of DHF was the pre-test value ( 12.9) post-test (14.2) means an increase of 1.3% p=0.003. The attitude that increased the most was the effort to control DHF with a pre-test value (9.4) post-test (48.2%) increased by 38.8% p = 0.000, while the smallest increase was the attitude of responsibility for controlling DHF with a pre-test value. -test (53.32) post-test (53.50) increased by 0.18% p=0.737. The behavior with the highest increase in value was about larval control with a pre-test score (4.75) post-test (37.78) means an increase of 33.0% p = 0.000, while the smallest increase is the behavior of draining the water tank with the pre-test (26.87) post-test (35.83) increasing 8.96% p = 0.002.
Conclusion: Health education through counseling methods is effective in increasing the knowledge, attitudes and behavior of Jumantik Cadres in preventing dengue fever in Palu City, Central Sulawesi and Pasangkayu Regency, West Sulawesi

Published: March 2022

Abstract:
Aim: Assessment of antibacterial effect and fluoride release on glass ionomer cement (GIC) modified by different concentrations of gallic acid (GA) and their effect on working and setting time.
Methodology: Four groups were tested, group I (control non modified group) and groups II-IV represent GIC modified by GA in three different concentrations (125mg/ml, 62.5mg/ml and 31.25mg/ml GA powder / GIC liquid respectively). Antibacterial effect against Streptococcus Mutans (S. Mutans) was determined after 24hr by broth dilution method. Fluoride release was evaluated after three time intervals 24, 48 and 96hr using spectrophotometer. Working and setting time were measured in all groups by indentation method.
Results: Increasing the concentration of GA significantly increase the antibacterial effect. For all time intervals, the highest fluoride release were observed in group IV and the lowest were in group I. After 24hr groups II, III and IV were significant to group I, while after 48 and 96hr group IV was significant to group I. In addition, working and setting time significantly increased with increasing the GA concentration.
Conclusion: Gallic acid improve the antibacterial effect of GIC against S. Mutans and also improve the fluoride release. The increase in working and setting time of GA modified groups were still within the limit given by ISO 9917–1:2007 specifications.

Published: March 2022

Cutaneous B-Cell Lymphoma is a rare type of cutaneous lymphoma with a plethora of clinical manifestations ranging from macules, papules, nodules, or plaques. The lesions are often painless and certain subtypes such as the primary cutaneous follicle center lymphoma (PCFCL) are indolent. The disease is often misdiagnosed with other dermatoses including bacterial and fungal infections. Here we report a 55-year-old female patient with clinical manifestations resembling multibacillary leprosy that was then confirmed to be PCFCL through aid of dermoscopy and histopathology. The patient then undergone chemotherapy using the R-CHOP regiment which resulted in significant clinical improvement and no signs of metastases or extracutaneous involvement upon follow-up.
