The System of Information Processing Standards as a Prerequisite to Fostering Students’ Academic Ethics Development
Authors: Еременко Т.В. 
Published: February 2023

Проведен анализ этических норм как правил и предписаний, регулирующих работу с информацией, с целью раскрытия их потенциала в формировании у студентов ключевых ценностей академической морали. Актуальность исследования определяется уникальной ролью педагогической среды вуза в формировании таких ценностей и их значением для всей последующей профессиональной карьеры выпускников. В исследовании применены методы теоретического анализа литературы, библиометрии, обобщения, систематизации и сравнения. Исследование содержания этических норм показало, что целенаправленное, последовательное и неукоснительное следование этим нормам выступает детерминантой успешного формирования у студентов академических ценностей честности, уважения и ответственности. Как результат исследования представлена описательная характеристика двух уровней вузовского пространства академических ценностей: фундаментального и репрезентации, которые находятся в динамичном взаимодействии. Фундированные ранее индикаторы академических ценностей на уровне их репрезентации раскрыты через нормы работы студентов с информацией. Структура пространства таких конкретных ценностей, как честность, уважение и ответственность, визуализирована на схемах. Подробно описаны основные виды нарушений норм работы студентов с информацией, также сконцентрированные под эгидой академических ценностей.
The article analyzes ethical norms as rulesthat regulate information processing in order to investigate their potential as a prerequisite to fostering the values of academic ethics in students. The relevance of the research is predetermined by the unique role university teachers play in the development of academic ethics as a key ingredient of career success. The research employs theoretical analysis, bibliometric analysis, generalization, systematization, comparative analysis. The investigation of ethical norms shows that by purposefully, consistently and continuously adhering to ethical norms, students develop such academic values as honesty, respect, responsibility. The research describes two types of academic values typical of the university environment, namely fundamental and represented as dynamic interaction. Previously funded indicators of academic values are represented as students’ information processing standards. Honesty, respect and responsibility as basic academic values are visually represented by diagrams. The article provides a detailed description of some violations of information processing standards, which contradict academic values.
Asteroseismology of the Pulsating Extremely Low-mass White Dwarf SDSS J111215.82 + 111745.0: A Model with p-mode Pulsations Consistent with the Observations
Authors: Su 苏 Jie 杰 , Li 李 Yan 焱 
Published: January 2023

Abstract
SDSS J111215.82+111745.0 is the second pulsating extremely low-mass white dwarf discovered. Two short-period pulsations, 107.56 and 134.275 s, were detected on this star, which would be the first observed pressure mode (p-mode) pulsations observed on a white dwarf. While the two potential p-modes have yet to be confirmed, they make SDSS J111215.82+111745.0 an interesting object. In this work, we analyzed the whole set of seven periods observed on SDSS J111215.82+111745.0. We adopt three independent period-spacing tests to reveal a roughly 93.4 s mean period spacing of ℓ = 1 g-modes, which gives added credence to the ℓ = 1 identifications. Then we perform asteroseismic modeling for this star, in which the H chemical profile is taken as a variable. The stellar parameters M = 0.1650 ± 0.0137 M
☉ and T
eff = 9750 ± 560 K are determined from the best-fit model, and the H/He chemical profiles are also defined. The two suspected p-modes are also well represented in the best-fit model, and both the stellar parameters and the pulsation frequencies are in good agreement with the values derived from spectroscopy.
Orbital Migration of Protoplanets in a Marginally Gravitationally Unstable Disk. II. Migration, Merging, and Ejection
Authors: Boss Alan P. 
Published: January 2023

Abstract
Protoplanets formed in a marginally gravitationally unstable (MGU) disk by either core accretion or disk instability will be subject to dynamical interactions with massive spiral arms, possibly resulting in inward or outward orbital migration, mergers with each other, or even outright ejection from the protoplanetary system. The latter process has been hypothesized as a possible formation scenario for the unexpectedly high frequency of unbound gas giant exoplanets (free floating planets, FFPs). Previous calculations with the EDTONS fixed grid three-dimensional (3D) hydrodynamics code found that protoplanets with masses from 0.01 M
⊕ to 3 M
Jup could undergo chaotic orbital evolutions in MGU disks for ∼1000 yr without undergoing monotonic inward or outward migration. Here the Enzo 2.5 adaptive mesh refinement 3D hydrodynamics code is used to follow the formation and orbital evolution of protoplanets in MGU disks for up to 2000 yr. The Enzo results confirm the basic disk fragmentation results of the EDTONS code, as well as the absence of monotonic inward or outward orbital migration. In addition, Enzo allows protoplanet mergers to occur, unlike EDTONS, resulting in a significant decrease in the number of protoplanets that survive for 1000–2000 yr in the Enzo models. These models also imply that gas giants should be ejected frequently in MGU disks that fragment into large numbers of protoplanets, supporting ejection as a possible source mechanism for the observed FFPs.
Les vulnérabilités de jeunes ruraux précaires : comparaison entre des jeunes nomades saisonniers viticoles et des jeunes non diplômés en milieu rural néo-aquitain
Authors: Reversé Clément , Auger Émilie 
Published: January 2023

Résumé : Bien que les recherches s’intéressent de plus en plus aux problématiques liées à la jeunesse en milieu rural, les jeunes circulant dans les espaces ruraux sont encore sous-étudiés et font partie d’une jeunesse invisibilisée qui peine à faire entendre sa voix dans la sphère publique. Pour autant, ces jeunes méritent notre intérêt du fait qu’ils vivent, ou circulent, dans des espaces ruraux hétérogènes qui sont intégrés aux enjeux professionnels et économiques globalisés et libéralisés de notre société contemporaine. Dans ce contexte particulier, l’article s’intéresse aux convergences et aux multiplications des vulnérabilités induites ainsi qu’à leurs particularités telles qu’elles sont vécues par des jeunes non diplômés et des jeunes nomades saisonniers viticoles vivant, ou circulant, dans des espaces ruraux de Nouvelle-Aquitaine.

Authors: Herrera Eloisa , Rutherford Wendy , Plume Tracy , Fields Willa , Mollon Deene 
Published: January 2023

Background:
Clinical staff showed a knowledge deficit with identifying and managing delirium. The effect of a validated assessment tool and delirium education on staff knowledge and confidence and patient outcomes was analyzed.

Method:
A descriptive qualitative and quantitative pre- and postintervention study analyzed the demographics of patients with stroke and clinical outcomes pre- and postimplementation of an assessment tool and delirium staff education.

Results:
Early and frequent delirium assessments, use of an assessment tool, a delirium order set, and education for clinical staff resulted in increased knowledge and confidence with identifying and managing patients with stroke, an increase in the number of patients with stroke discharged home, and decreased incidence of hospital-acquired urinary tract infection and pneumonia.

Conclusion:

Delirium education positively impacts staff knowledge and confidence with the identification and management of delirium. Patients with an acute stroke may benefit from early and frequent delirium assessments. Staff education, structured assessment frequency with a validated assessment tool, and specific interventions affect patient outcomes, such as infection rates and discharge level of care.

Feasibility of the expectation-maximization algorithm for assessing individuals with different sensory perceptions in discrimination of specialty coffees
Authors: Oliveira Larissa Karolina de , Resende Mariana , Borém Flávio Meira , Cirillo Marcelo Angelo 
Published: January 2023

The results of sensory evaluations of coffees are associated with latent factors, such as the particular subjectivity of each individual. Based on the foregoing, assessing the quality of a sensory panel for product discrimination basically depends on the statistical methodology to be used in data analysis. Following this argument, this study aimed to evaluate the feasibility of the EM - Expectation Maximization algorithm in discriminating groups of individuals, characterized by the degree of experience and knowledge in sensory analysis of coffees of different varieties, produced in the Serra da Mantiqueira micro-region, with different processing and altitudes. The main advantage of this algorithm is the fast convergence, when the current solution approaches the optimal solution with high precision. The disadvantage is because it is a deterministic optimization technique, which can only achieve a local optimization depending on the initialization, i.e., initial values input in the iterative procedure. It can be concluded that estimates of the correlation matrices obtained by the EM algorithm showed that the final grade has a greater influence of sweetness, in addition to discriminating groups of consumers with different sensory perceptions and in situations where the number of individuals in each group is unknown, the EM algorithm was accurate in estimating the proportion of individuals belonging to each group, assuming that the correlations of sensory responses follow a bivariate normal distribution.
Accelerated swelling of wood for rapid dimensional stability
Authors: Almeida Tiago Hendrigo , Icimoto Felipe Hideyoshi , Almeida Diego Henrique , Aquino Vinicius , Christoforo André Luis , Lahr Francisco Antonio Rocco 
Published: January 2023

Dimensional stability of wood can be determined by measuring the total swelling percentage between 0% and FSP moisture content according to the ABNT NBR 7190 (Associação Brasileira de Normas Técnicas [ABNT], 1997). Wood dimensional variation by the moisture content modifications must influence both structural elements and connections into timber structures. The wood swelling procedure according to the Brazilian code for saturation of wood samples can take more than a month, but the use of autoclave devices may accelerate this activity, making easier the dimensional stability determination. This paper aims to investigate the possibility of accelerating the wood swelling activity using an autoclave device, considering the Brazilian code for thirteen Brazilian commercial wood species. Contrast test for comparison between accelerated process (Stage 4 – 225 min. at 0.49 MPa pressure) and the conventional procedure for wood swelling resulted in p-value equal to 0.0730 and the average difference between groups about 1.1307% (varying between -0.0541 and 2.3156 with 95% confidence level). According to results, 225 min. at 0.49 MPa pressure provides an equivalent wood swelling compared to the conventional procedure, which can make faster the wood dimensional stability evaluation according to the ABNT NBR 7190 (ABNT, 1997).

Published: January 2023

Background:
Due to the high prevalence of addiction in society and the need to its attention, various methods are used for addiction withdrawal. The side effects of some methods restrict their use and increase the risk of recurrence. One of the Iranian useful methods is consumption of opium tincture (OT) that may cause brain structure and memory defects. Hence, this study aimed the effects of different doses of OT on memory and hippocampal neurons with the use of an antioxidant such as various concentrations chicory.

Materials and Methods:
In the present study, 70 Wistar rats were randomly divided into 10 groups and the effect of various doses of chicory extract and OT were assessed on memory by the passive avoidance test. The neurons and astrocyte cells numbers in dentate gyrus were investigated, using histological examination.

Results:
In passive avoidance test, the total time in dark compartment was significantly more in groups with 100 and 75 μl OT compared with control and normal saline groups (P < 0.001). Traffic number results showed that there was a significant difference between T100 and control groups (P > 0.05). Moreover, initial latency time was significantly shorter in groups with 75 and 100 μl of OT compared with control and normal saline groups (P < 0.05). However, the presence 250 mg/kg of chicory increases granular layer thickness of dentate gyrus and number of neurons.

Conclusion:
The use of 250 mg/kg of chicory extract may be promising strategy for inducing neurogenesis and this dose could prevent neural damage.

Authors: Sharma Mini , Kataria Dinesh , Raut Nitin B. , Ramesh Om Sai , Rehman Sajjadur , Gracy BK 
Published: January 2023

Background:
The planet has been hit by the novel coronavirus since December 2019, which has not only affected the day-to-day activities but has also affected the health-seeking approach of the general population. The reports from the National Institute on Drug Abuse survey hint toward a rise in opioid use in the states. Even in India, the utilization of health services, especially the outpatient department (OPD) and opioid substitution clinics have been affected due to the impact of COVID-19 and subsequent national and regional lockdowns. The Indian studies reflect upon the experience and measures to continue the treatment facilities in substance users, yet none are available to reflect upon the impact of COVID-19 on the pattern of opioid use or functionality of OPD services.

Objective:
The objective of this study is to study the impact of COVID-19 pandemic on treatment seeking among opioid users from OPD-based opioid treatment centers: a retrospective study.

Methodology:
A retrospective study was done in an OPD-based opioid treatment center of a tertiary care hospital to analyze the impact of COVID-19 on treatment-seeking opioid users by comparing the data of pre-COVID-19 (April 2019–March 2020) and during COVID-19 (April 2020–March 2021) OPD visits by opioid users. The OPD visits data were collected, including the number of visits, the total number of buprenorphine tablets dispensed, and the dose of buprenorphine consumed per month. The data collected were further analyzed for the descriptive and analytic statistics using the SPSS software version 23.0.

Results:
During the pre-COVID-19 (April 2019–March 2020) duration, there were a total of 1104 (average 92/month) OPD visits and 4818 (Average 401/month) buprenorphine tablets were dispensed; whereas during the COVID-19 year (April 2020–March 2021), it was 980 (average 81.66/month) visits and 5174 (431/month) tablets. The results were further compared using the paired t-test, which was found to be statistically significant for the number of tablets dispensed, whereas not statistically significant for the number of OPD visits and doses.

Conclusion:
Although the COVID-19 pandemic has affected the feasibility to seek treatment in opioid users, it has not significantly affected OPD visits for opioid treatment at our center. Although the policy changes such as Indian Psychiatry Society (IPS) interim guidelines for opioid substitution therapy have been beneficial to facilitate the harm reduction and treatment-seeking attitude and have not affected the treatment seeking as expected due to lockdown and transportation which have been a hurdle. Further regulations on opioid treatment OPD, Tele-consultation services and mobile mental health services may be helpful to ensure continuity of treatment and harm reduction among the opioid users.

Authors: Nemade Shyam H. , Kamal Meherbano M. 
Published: January 2023

Introduction:
In the diagnosis of malignant tumors, cytological examinations of various body fluids are useful. For the preparation of body fluid, many methods are used till date. The use of liquid-based cytology is new upcoming in the field.

Aim:
To examine the performance of liquid-based cytology on body cavity fluids as compared to conventional cytopreparatory techniques.

Methodology:
In the present study, 700 body fluid samples were processed by both liquid- based cytology (BD SurePath™) and conventional cytopreparatory technique (Thick & Thin). The performance of both techniques was compared in terms of “smear quality” and “overall diagnostic test performance.”

Results:
Out of 155 body fluid samples from proven malignancy patients, 32 (20.65%) were reported as Positive for malignancy, 23 (14.84%) as Suspicious of malignancy, and 100 (64.51%) as Negative for malignancy by CS (Thick and Thin). A total of 44 (28.39%) were reported as Positive for malignancy, 12 (7.74%) as Suspicious of malignancy, and 99 (63.87%) as Negative for malignancy by LBC.

Conclusion:
Liquid-based cytology is advantageous over conventional techniques in cytomorphology of body fluids, but not better in sensitivity and specificity. Also saves cytopathologist's valuable time for screening.
The baneful alliance of COVID-19 and mucormycosis
Authors: Singh Anshu , Kumar Vijay , Kumar Vikul , Verma Nidhi 
Published: January 2023

Background:
Mucormycosis, once a rare fungal disease, has now shown a surge in cases, and its epidemiology in India is intriguing. Rising incidence confers the necessity of defining the demography of the population at risk, early diagnosis, and recommendations for the management of mucormycosis in patients with coronavirus disease (COVID-19) infection.

Aims:
To study the clinico-epidemological profile, risk factors, and histopathological features of COVID-19-associated Mucormycosis (CAM).

Setting and Design:
This is a retrospective observational study.

Material and Methods:
Fifty-six biopsy specimens taken from patients of COVID-19 with clinical suspicion of mucormycosis were included.

Results:
Diabetes mellitus, corticosteroids, and oxygen therapy were the most common risk factors associated with CAM. The mean duration between the onset of symptoms of COVID-19 and onset of CAM was 25.2 ± 15.3 days. Rhino-orbito-cerebral mucormycosis (ROCM) was present in 24.5% of the cases, with a survival rate of 58.3%. Histopathology showed tissue invasion by branching broad-based, pale, fungal hyphae consistent with mucor in 49 (87.5%) cases. Inflammation was acute neutrophilic type in 61.2% of the patients with a survival rate of 63.33%. The survival rate with chronic non-granulomatous and chronic granulomatous was 100% and 81.8%, respectively.

Conclusion:
Keeping a high index of suspicion for mucormycosis in COVID-19 by all medical fraternities of the health community in the existence of risk factors is the need of the hour for prompt diagnosis. Biopsy of antral necrotic tissue should be performed immediately after suspicion for histopathological study to confirm the diagnosis of mucormycosis and predict prognosis depending on the type of inflammation incited, fungal morphology, load, and necrosis.

Authors: Varghese Shereen R. , Kwatra Gagandeep 
Published: January 2023

Background:
The first objective of the Global Action Plan proposed by the WHO in preventing and controlling Antimicrobial resistance is to improve awareness and understanding of antimicrobial resistance through effective communication, education and training. Self-directed learning is a student oriented teaching learning method ideal for imparting lasting knowledge on topics of national and global importance such as antimicrobial resistance among medical students, which will help them develop an in-depth understanding of the topic and hence the aim of this study was to develop and implement a Self Directed Learning Module on Antimicrobial Resistance.

Material and Methods:
The study was conducted in the department of Microbiology with the Phase 2 medical students. Four self-directed learning sessions were developed and disseminated which included case scenarios, class assignments, obtaining antibiotic history from admitted patients, brain storming sessions, final assessment and feedback from students and faculty.

Results:
62 out of 80 students gave their consent for the study. 72.6% students attended all the SDL sessions. 55 students gave their final assessments and feedback and all students scored above 50% marks. More than 70% of students said that the SDL aroused curiosity about the topic, while making it interesting, interactive and enjoyable.

Conclusions:
The self-directed learning module on antimicrobial resistance evoked interest and enthusiastic participation among the medical students. The discussions, assignments and the brainstorming sessions helped to deepen their knowledge on this emerging threat at the local, national and global levels.
Evaluation and prognostic significance of tumor budding in pancreatic ductal adenocarcinomas
Authors: Argon Asuman , Öz Özden , Kebat Tulu Ayata 
Published: January 2023

Aim:
In this study, it was aimed to investigate the prognostic importance of Tumor budding (TB) in Pancreatic ductal adenocarcinomas(PDAC) and its correlation with histopathological findings according to the International Tumor Budding Consensus Conference(ITBCC) grading.

Material and Methods:
A total of 75 patients diagnosed with PDAC were included in this study. The demographic features of the cases (age, sex) and the macroscopic features of the tumors (localization, size) were obtained from the electronic archive system. All Hematoxylin-Eosin-stained sections were re-evaluated in terms of differentiation, presence of lymphovascular (LVI) and perineural invasion(PNI), surgical margin positivity, primary tumor(pT), lymph node metastasis(LNM) and tumor budding. Statistically, Chi-square test, cox-regression and Kaplan-Meier test were performed.

Results:
Thirty four of the cases were female and 41 were male. The mean age was 64.21±9.71years. The degree of TB was TB-few in 17 cases, TB-moderate in 25cases, and TB-high in 33cases. LVI, PNI, LNM and TB-high were poor prognostic factors. Moreover, TB-high was related with poor differantiation, LVI, PNI, LNM and short survival time. Tumor budding was independent negative prognostic factor in multivariable model analyzes.

Conclusion:
ITBCC scoring can also be used in PDACs. In addition, high tumor budding was a poor prognostic feature and might be a target for tumor-specific treatments as it could be a predictive finding for the locally invasive character of the tumor. Evaluation and grading of TB thought to represent EMT may be a histological feature that can be used in tumor selection for advanced molecular methods to identify subtypes that may be associated with poor prognosis and drug resistance.
