Background:The transversus abdominis plane (TAP) block is a well-known regional nerve block that is used for the pain control after various inguinal andabdominal surgeries. The most effective and well known method of administering the TAP block is under ultrasound guidance.Till now only few studies have evaluated analgesic efficacy of TAP block in Abdominoplastysurgical procedure, in which post-operative pain is a major concern for both surgeon as well for the patient. Objectives:We conducted retrospective cohort study to assess efficacy of ultrasound-guided bilateral TAP block, in controlling post-operative pain in abdominoplasty patients. Methods:Sixty Patients who had undergone Lipoabdominoplasty procedurewere studied retrospectively. The patients who had received TAP block were assigned as groups A and those patients who had not received any TAP block were assigned as group B, with thirty Patients in each group.The patients in two groups were compared for their demographic characteristics, pain intensity on mobilization, time to first rescue analgesic dose (visual analog scale (VAS) score ≥ 5 or on demand), opioid consumptionand incidence of nausea-vomitingepisodes during first post-operative 24 hours. Results:The patients in two groups were similar in demographic characteristics. Patients in group A (TAP block group) had required significantly smaller mean dose of postoperative opioids (Group A: 5mg Group B: 75 mg P = <0.000) and hadsignificantly longer mean time of first request for analgesic medication (Group A: 8 hours 11 minutes Group B: 1 hours 20 minutes P = <0.000).Median VAS score on mobilization was significantly lower in Group A(group A: 1 Group B: 5).Only Three patients in group A as compared to 18 patients in group B had experienced nausea and vomiting in post-operative period. Conclusions:The ultrasound guided TAP block provide more effective analgesia after Lipoabdominoplasty, which allows more comfortable early post-operative mobilization, decreases opioid requirement as well as opioid related side-effects, Therefore ultrasound guided TAP block should be considered in most of lipoabdominoplasty patients for better patient experience and outcome.

Published: November 2020

A PROPOSITION FOR TEACHING LABORATORY OF QUALITATIVE ANALYTICAL CHEMISTRY. Teaching laboratory of qualitative analytical chemistry is still a controversial issue in chemistry courses. However, important researchers and educators in chemistry recognized and highlighted the importance that the contents of this discipline represent in the formation of chemists, once it can provide handling and understanding of microscopic phenomena based on the observation of their macroscopic effects, once such reactions and phenomena are the basis of important instrumental methods of analysis. Thus, a proposal based on a bottom-up approach has been developed, starting with the observation of different reactions of cations in laboratory, followed by a search for the reaction responsible for each resulting phenomenon observed during the experimental step. Then these reactions are related with the separation procedures of each group of cations. Eventually the separation of these groups can also be performed depending on the time available. The proposal has been applied in teaching laboratory of qualitative analytical chemistry at Instituto de Química de São Carlos/USP since 2015, where the discipline is offered duirng 4 hours/week, and a positive feedback regarding the evolution of the methodology and its acceptance by students. Good results were also obtained concerning the appropriation of the contents by the students, using the proposal.

Authors: Azeeze Mohamed S.T.A. , Santhosh Shanthi B. , Manjari Murugesan S. , Meyyanathan Subramania N.
Published: November 2020

Background:

Conventional medicines, along with herbal formulations of Chinese, serve
as the primary source and hub of active new drugs where the initial research concentrates on the extraction
and isolation of bioactive lead compound(s) to treat several diseases largely for cancer.
Plant-derived natural products and their analogs reveal a significant source of several clinically useful
anticancer agents. Herbs and herbal derived active compounds play an unavoidable role in the
treatment, drug discovery and delivery for decades, as evidenced by numerous existing marked
drugs and various cancer-related molecular targets in clinical development.

Objective:

Solubility, resistance and metabolic limitations of the drug can be overcome by suitable
molecular modifications. Due to enhancements in tumor targeting technology, some agents who
failed in earlier clinical studies are also stimulating renewed interest. In this connection, In Vitro-In
Vivo Correlation (IVIVC) plays an important role in the development of dosage forms in the field
of pharmaceutical technology.

Conclusion:

IVIVC tool fastens and improves the drug development process and product quality,
which is also utilized in internal control for scale-up to improve formulations and alternative production
processes. Most importantly, this IVIVC tool lessens the number of human studies during
new pharmaceuticals developments. In this review, we would like to grab the attention of readers
to the importance and significance of IVIVC for natural products of anticancer drugs examples
such as Docetaxel, Etoposide phosphate, 6-Gingerol, Capsaicin, etc.
Histone Deacetylase Inhibitors Prevented the Development of Morphine Tolerance by Decreasing IL6 Production and Upregulating μ-Opioid Receptors
Authors: Jindal Sahil , Kumar Nitesh , Shah Aarti Abhishek , Shah Abhishek , Gourishetti Karthik , Chamallamudi Mallikarjuna R.
Published: November 2020

Background:

Morphine tolerance on long-term usage leads to chronic pain conditions.
Preclinical studies demonstrated that the upregulation of HDACs is associated with a decrease in
the sensitivity of μ-opioid receptors, which results in morphine tolerance.

Objective:

The present study was designed to assess the influence of the selected known HDAC inhibitors
(NMJ2 and NMJ3) on the pain tolerance induced by chronic administration of morphine in
Balb/c mice.

Methods:

In the present study, morphine was administered in incremental doses 1, 2, 3.6, 6.5, 11.2,
21, and 21 mg/kg daily for seven days to develop morphine tolerance. The nociceptive thresholds,
analgesia, and tolerance were assessed 30 min after morphine administration alternatively from 1st
day to 7th day using the hot plate and mechanical allodynia methods.

Results:

The morphine control group showed a reduction in the Paw Withdrawal Threshold (PWT)
and the percentage Maximum Possible Effects (MPEs). In contrast, the combination of SAHA and
test drugs with morphine increased the PWT and MPEs as compared to the morphine alone group.
Administration of morphine alone also showed an increase in the production of the pro-inflammatory
mediator, IL-6, and down-regulation of the μ-opioid receptor in the brain tissues. Treatment
with HDAC inhibitors, SAHA, and test drugs showed a reversal in these changes.

Conclusion:

Results indicated that HDAC inhibitors were involved in the prevention of morphine
tolerance in normal mice by inhibiting pro-inflammatory marker production and by increasing the
sensitivity of neurons towards morphine in producing an analgesic effect in morphine tolerated
mice.

O surto de desenvolvimento observado na metodologia das Ciências do Comportamento Humano, na última década, impõe revisão completa dos métodos de ensino no campo da Administração. Tal ensino deve, necessariamente, basear-se em observações sistemáticas (pesquisas) da realidade político-administrativa. No Brasil, onde são grandes as discrepâncias entre a estrutura formal e a realidade funcional, em virtude do ritmo acelerado do seu processo de desenvolvimento, imperiosa se faz a realização de pesquisas dentro das técnicas modernas. Há necessidade de se criar uma nova mentalidade, uma mentalidade voltada para o estudo dos fenômenos tais como eles se apresentam no contexto social. A mera argumentação deve ceder lugar à linguagem dos fatos cujos resultados nos levem a novas descobertas. A publicação do presente projeto de pesquisa visa despertar o interesse por esta técnica pouco difundida no Brasil.

Racial Variation in the Association between Positive Urgency and Body Mass Index among American Children
Authors: Assari Shervin
Published: November 2020

Background: Positive urgency reflects a specific facet of impulsivity and correlates with several health-related risk behaviors such as obesity, food addiction, and substance use. However, less is known about whether positive urgency is similarly or differently associated with high body mass index (BMI) across diverse racial groups. Aim: The aim of this study was to investigate racial differences in the associations between positive urgency and BMI in 9-10-year-old children in the US. Materials and Methods: This cross-sectional study used the Adolescent Brain Cognitive Development (ABCD) study. Participants were 11590 American children between ages 9 and 10 years old. The independent variable was positive urgency measured by the Urgency, Premeditation (lack of), Perseverance (lack of), Sensation Seeking, Positive Urgency, Impulsive Behavior Scale (UPPS-SS). The primary outcome was BMI. Race was the moderator. Demographic variables (age and sex) were covariates. Mixed-effects regression models were used for data analysis to adjust for the nested nature of the ABCD data. We also used weights (propensity score) to generate nationally representative results. Results: In the pooled sample, race showed a statistically significant interaction with positive urgency on children’s BMI, indicating a stronger effect of positive urgency on BMI for White children, compared to African American children. Conclusion: The association between positive urgency and BMI seems to be weaker in African American children than in White American children. The role of individual-level risk factors such as impulsive traits may be smaller for African American than White American children. Future research should study the role of obesogenic environments and other area level indicators in altering the effects of individual-level risk factors on BMI and obesity.
THE CORRELATION OF MATRIX METALLOPROTEINASE-9 WITH STROKE AND PREVALENCE, RISK FACTORS, AND KNOWLEDGE OF STROKE AMONG PALESTINIANS
Authors: ATTILI ROZAN , A HEJAZ HATEM
Published: November 2020

Objectives: The research study aims to estimate the prevalence of the stroke, to evaluate the stroke associated risk factors, and to determine the factors and symptoms associated with the knowledge of the stroke among the Palestinian population. Furthermore, to find the association between matrix metalloproteinase-9 (MMP-9) levels and the stroke, the concentration of MMP-9 in the serum of stroke patients was measured.

Methods: The research study includes a cross-sectional survey that was conducted. The serum MMP-9 levels were also measured in 11 stroke patients using an ELISA reader. Statistical analysis was performed by GraphPad Prism version 8. Sociodemographic characteristics of stroke patients associated with stroke among the Palestinian population were also obtained and analyzed.

Results: The higher incidence of the stroke was in the patient’s ages between 51 and 60 years old, with 30 patients (46%) of the total stroke patients. The majority of the stroke patients 40 (60.6%) were having enough income. Most of the stroke patients (29, 43.9%) were none educated. The majority of the stroke patients 48 (72.2%) had a family member/s who has been diagnosed with a stroke. Most of the stroke patients 60 (90.9%) have sudden numbness, weakness in the face, arms, and legs. All the samples analyzed showed a marked increase in MMP-9 concentration.

Conclusions: The prevalence of stroke and the high risk of stroke were high among adults aged ≥51 years in Palestine. Hypertension was the highest risk factor for stroke. The serum MMP-9 could be an important prognostic factor for the stroke.
RUSKO-KINESKA SARADNJA U VOJNO-BEZBEDNOSNIM PITANjIMA I ENERGETICI POSLE UKRAJINSKE KRIZE
Authors: Nedic Pavle
Published: November 2020

Saradnja Ruske Federacije i Narodne Republike Kine se razvijala nakon Hladnog rata, ali jedna drugoj nisu bile u spoljnopolitičkom fokusu. Ukrajinska kriza 2014. menja ovu situaciju. Kao posledica drastičnog pogoršanja odnosa sa SAD i Evropskom unijom, Rusija se okreće znatno intenzivnijoj saradnji sa Kinom. Ona se posebno ispoljava u dve oblasti: vojno-bezbednosnim pitanjima i energetici. Dve države su realizovale nekoliko izuzetno važnih ugovora o kupoprodaji oružja i vojnih tehnologija. Zajedničke vojne vežbe su češće i izvode se na provokativnijim lokacijama. Dodatno, Kina postaje sve veći potrošač nafte i gasa, a Rusija se pozicionirala kao jedan od primarnih izvoznika ovih resursa u Kinu. Kineske kompanije imaju udeo u nekoliko značajnih ruskih energentskih projekata, a kineske banke su bile spremne da daju značajne zajmove za njihovu realizaciju. Budući da će se zaoštravanje odnosa Moskve i Pekinga sa zapadnim državama nastaviti, saradnja Rusije i Kine u ovim oblastima će se dalje razvijati. Ipak, ne treba očekivati stvaranje zvaničnog rusko-kineskog saveza.
An Unfair Game of Virtual Hide-and-Go-Seek: The Passive Collection of Children's Information Online
Authors: Korajlija Andrea
Published: November 2020

In this paper, I examine the regulatory deficiencies surrounding children’s online privacy. Specifically, I assess how the passive collection of children’s information through their parents is permitted under the current legislation. I examine two online activities of parents that jeopardize their children’s privacy: (1) “sharenting” on social media platforms; and (2) the use of pregnancy and parenting mobile applications. I outline the consequences children face because of this unconsented passive collection of their information enabled by their parents’ technology use. Lastly, I call for more stringent regulation. We need legislation that explicitly differentiates children’s privacy interests and offers specific safeguards for them to preserve their digital identity and overall safety.

Global Leadership and Change Management on the Example of the German Automotive Industry
Authors:   University of Latvia, Filkorn Markus
Published: November 2020

Change Management is a term which is omnipresent in nowadays discussions of all areas, be it politically or economically motivated. This article discusses different scientific process theories of Change Management, such as Teleological theories, Dialectical theories, Life cycle theories and Evolutionary theories, that all regard change as involving a number of events, decisions and actions that are connected in some sort of sequences, but distinguish themselves when understanding change as a structured process. Moreover, the linkage of the interconnected fields of Change Management and Strategy Management are seized. Lastly, the importance and different role of Leadership and Management are discussed before reviewing the historic evolvement of the German automotive industry, as well as its current challenges. It is concluded why Change Management in this industry is nowadays more important than ever due to fierce global competition, regulatory requirements and different technological developments all ending up in distinct client requirements and expectations.

Published: November 2020

E-commerce activities in Nigeria are rapidly growing as a result of vast improvements in telecommunication services. And e-banking is one area of e-commerce that has proven successful in Nigeria. The growth of internet users from year 2000 to 2019 is sporadic as it recorded 73% growth rates. This study explores the benefits of e-commerce and the challenges of e-commerce that inhibit its successful operation in Nigeria. Survey research was adopted for this study. The questionnaire was designed and administered randomly to 1200 respondents. Collected data were analysed using Statistical Package for Social Science (SPSS). The findings indicate that the major benefits of e-commerce adoption in Nigeria are increased sales, competitive advantage, customer loyalty, increased automation of processes, extended application of new technology, better knowledge management, and enhanced well-being and education of customer. The key challenges identified in the Nigerian context include power outages and frequent power interruption, insecurity, technology cost, lack of trust in web retailers, software compatibility, and acquisition of IT skilled personnel. The study recommends, among other issues, the need for adequate publicity on e-commerce with emphasis on e-shopping, e-banking, and e-business.
Formalization of decision making process on including geophysical maps into integrated atlases
Authors: Loginov D.S. , Krylov S.A.
Published: November 2020

The authors’ approach to formalizing decision-making on including geophysical maps into integrated atlases is considered in the article. The method of taking factors characterizing the spatiotemporal distribution of geophysical fields within the mapped area into account is proposed. The issues of creating and analyzing maps of direct and estimated factors using previously published ones and data from open geological and geophysical resources are considered. The matrix for the geophysical section of the atlas is developed; it defines the necessary criteria for all the possible options of placing geophysical maps in the atlas. Experimental testing of the method was performed on the example of the Russian Federation subjects. As a result, a pivot table and a map were compiled; they are showing recommendations for incorporating geophysical maps into integrated atlases of the Russian Federation. The proposed approach to formalizing the matter of including the geophysical section in the atlas is characterized by flexibility in decision making; it enables determining the composition of maps of specific fields in the section quickly and automatically, and can be applied for different levels of mapping (global, regional, local and municipal).
Synthetic Observational Health Data with GANs: from slow adoption to a boom in medical research and ultimately digital twins?
Authors: Georges-Filteau Jeremy , Cirillo Elisa
Published: November 2020

After being collected for patient care, Observational Health Data (OHD)
can further benefit patient well-being by sustaining the development of
health informatics and medical research. Vast potential is unexploited
because of the fiercely private nature of patient-related data and
regulation about its distribution. Generative Adversarial Networks
(GANs) have recently emerged as a groundbreaking approach to learn
generative models efficiently that produce realistic Synthetic Data
(SD). They have revolutionized practices in multiple domains such as
self-driving cars, fraud detection, simulations in the and marketing
industrial sectors known as digital twins, and medical imaging. The
digital twin concept could readily apply to modelling and quantifying
disease progression. In addition, GANs posses a multitude of
capabilities relevant to common problems in the healthcare: augmenting
small dataset, correcting class imbalance, domain translation for rare
diseases, let alone preserving privacy. Unlocking open access to
privacy-preserving OHD could be transformative for scientific research.
In the COVID-19’s midst, the healthcare system is facing unprecedented
challenges, many of which of are data related and could be alleviated by
the capabilities of GANs. Considering these facts, publications
concerning the development of GAN applied to OHD seemed to be severely
lacking. To uncover the reasons for the slow adoption ofGANs for OHD, we
broadly reviewed the published literature on the subject. Our findings
show that the properties of OHD and eval-uating the SD were initially
challenging for the existing GAN algorithms (unlike medical imaging, for
which state-of-the-art model were directly transferable) and the choice
of metrics ambiguous. We find many publications on the subject, starting
slowly in 2017and since then being published at an increasing rate. The
difficulties of OHD remain, and we discuss issues relating to
evaluation,consistency, benchmarking, data modeling, and
reproducibility.

The low-temperature transportation, a process of gathering and
transportation at ultrahigh water content, can incline the energy
consumption and elevate the efficiency of the surface gathering system.
Here we found that there is the risk of wall sticking of heavy oil in
the low-temperature transportation.In this work, a theoretical model of
boundary condition for heavy oil in low-temperature transportation based
on DLVO theory was proposed to predict the wall sticking occurrence
temperature. The outcomes of modeling results had a good agreement in
comparison with experiment results (error values:
0.1°C~1.5°C).Moreover, the interaction mechanism of wall
sticking was correlated well with the Hamaker constant, radius of oil
droplets, Ζeta potential, and Debye length.

The problem of bullying represents a priority institutional, as well as wider
social problem, and it needs to be addressed persistently and
systematically, bearing in mind the long-term negative consequences that it
leaves on all involved actors. In the school environment the most commonly
applied level of prevention is universal, i.e. primary prevention. The study
of the effectiveness of the application of various bullying prevention
programs shows that it is possible to identify certain characteristics of
effective programs. The given characteristics are systematized in terms of
those related to the program itself, the specifics of the school staff and
the teaching staff. In order for the school bullying prevention program to
give valid results, it is necessary to focus on two general goals: creating
a safe and supportive school environment - through changes at different
levels of school functioning in order to create an supportive school
climate, as well as the application of school rules against bullying; and
the development of individual interpersonal competences among students -
through the application of appropriate measures and activities at the
individual or group level, aimed at the development of interpersonal skills.
The process of designing school bullying prevention program should be based
on the analysis and understanding of the specifics and needs of the existing
school context.

Ensuring safety on the territory of the subject of the Russian Federation is a key aspect, including implementation of measures to ensure safety of the technogenic environment, which includes hydraulic structures, as well as hydraulic structures that do not have an owner or the owner of which is unknown or whose ownership rights were refused (ownerless hydraulic structures). Development and implementation of preventive measures to ensure safety of the technogenic environment contribute to the prevention of emergencies and the development of an algorithm for eliminating their consequences. Article 5 of Federal law № 117-FZ of July 21, 1997 «On safety of hydraulic structures» establishes the powers of the executive authorities of the subjects of the Russian Federation in the field of safety of hydraulic structures, one of which is the authority to develop and implement regional programs to ensure safety of hydraulic structures, including ownerless hydraulic structures. Despite the twenty third year period of validity for this federal law, most subjects of the Russian Federation do not have regional programs of ensuring safety of hydraulic structures, including ownerless hydraulic structures (for ownerless hydraulic structures, such a norm was introduced in 2013). In this case, the executive authorities of the subjects of the Russian Federation refer to the norm of p. 4 of Art. 25 of the Water Code of the Russian Federation, in accordance with which the programs of the subjects of the Russian Federation for the use and protection of water bodies or their parts located on the territories of the subjects of the Russian Federation were developed, approved and are being implemented. The absence in the subject of the Russian Federation of an approved regional program for ensuring safety of hydraulic structures creates the risk of occurrence of an emergency.

The coke foam formed from the intumescent paint at the beginning of the fire effect is a good heat insulator and allows to protect the building structure elements from critical heating (from 500 °C) for some time. However, violations of technology on the real object can cause coking defects. And an insufficiently accurate assessment of the quality of the intumescent coating and foam in the laboratory can endanger the fire hazard of an object at risk. There are oversimplifications, limitations, and uncertainties in the existing laboratory procedures for testing fire-retardant properties of the intumescent paints. In this regard, many problems arise. The main property of the intumescent paint is tested under the influence of fire, that is, after the formation of the coke foam. Therefore, the fire test should be carried out only after the coating is completely ready at the facility. Аlso the area of the test coating should be significantly larger (20–80 cm2) than that of laboratory samples, since the functioning of paint and foam in real conditions is somewhat different. Additional study is required of the number of properties and behavior of intumescent paints that are capable to cause hidden defects in the original coating and foam. The authors highlight two main factors that cause hidden defects: incorrect choice of the thickness of the intumescent paint layer and excessive dilution of it before applying. Currently, the regulatory documentation does not regulate such important properties of the coke foam as the density and thickness of the layer, which determine the structure fire safety. An important task of future research is to find the ways to quickly identify violations of paint manufacturing and application technology, which lead to a critical deterioration in the properties of the future coke foam. The ultimate goal of the study of the methodology of fire protection, the authors see in the development of a comprehensive technique for detecting hidden defects when testing fire-retardant properties directly at the object, at large areas of fire-retardant coating (20–80 cm2), with the subsequent restoration of this area if the intumescent paint passed the test.

Modern economic conditions, intensive modernization and digitalization of production, and the level of technologies require a change in the approach to training in the field of occupational safety and health. It is necessary to improve the methodology and organization of the educational process, training programs, material and technical base and logistics. Due to the appearance of Generation Z, the generation «born with gadgets in their hands», there was a huge gap between generations X, Y and Z (51–65, 31–50 and 18–30 years). The development of programs and training methods should consider generational psychophysiological features: the format, volume and speed of perception of information flows differ among employees of different generations. The main aspects of the methodology that are recommended to be used in the development of training programs and methods are considered and justified. The first aspect is the change in perception due to digitalization of the society and economy, as well as the use of modern means of communication. The «bandwidth» of intelligence was increased: faster and more data is perceived per unit of time, but the ability to concentrate was decreased. In Generation Z, in comparison with X and Y, the ability to hold attention on one object decreased from an average of 12 to 8 seconds. Constant communication in gadgets and the specific format of information on the Internet formed the new psychophysiological features: to operate with abstractions, pictures; «scan» the text, and not read in the usual sense of the word, etc.

Temperature is one of the environmental factors that has influences on the material properties, and its behavior in service life. In this study, effects of temperature and exposure duration on the ultrasound wave velocity, dynamic Modulus of Elasticity, Modulus of Elasticity in bending, and Modulus of Rupture were figured out by the transmission of ultrasound longitudinal wave and three points bending tests. According to results, all determined properties were decreased at intensive treatment conditions. Maximum decreases were 4.7, 16.6, 20.7, 34.1, and 8.7 % at 210 °C 8 h treatments for VLL, Edyn, MOE, MOR, and density, respectively. However, at moderate temperatures up-to 150 °C, properties (except density) were increased (VLL: 12.7%, Edyn: 20.2%, MOE: 18.1%, MOR: 11.7% at 80°C for 8h) with the increase in exposure time within the groups but decreased between the groups. Pearson correlation coefficients between the variables were ranged from 0.71 to 0.93 for Edyn-MOE, 0.47 to 0.85 for Edyn-MOR, 0.02 to 0.75 for Edyn-VLL, 0.71 to 0.88 for MOE-MOR, 0.02 to 0.78 for MOE-VLL, and 0.01 to 0.81 for MOR-VLL. Furthermore, R2 values were ranged from 0.7 to 0.9.
Lateral-Torsional Buckling Strength of Two-Span Glass Fiber Reinforced Polymer Beams
Authors: Sirjani Mojtaba B. , Razzaq Zia
Published: November 2020

This paper presents the outcome of a study of two-span glass fiber reinforced polymer (GFRP) I-section beams susceptible to lateral-torsional buckling when subjected to gradually increasing concentrated vertical load(s) in the presence of two different types of lateral bracing schemes. It is found that loading one span results in a smaller buckling load as compared with the cases with loading in both spans regardless of the type of bracing scheme used. Also, the study shows that the addition of midspan braces for the GFRP beams results in up to 5.5 times increase in the buckling load capacity.

COVID-19 is proving to be a double-edged sword for health care professionals. It is not only causing physical malfunctioning but mental suffering among medical undergraduates. This study demonstrates the psychological impact and various predisposing factors causing mental distress. This is a descriptive cross-sectional study involving 157 medical undergraduates of Third, Fourth, and Final year MBBS being trained in tertiary care hospitals of Rawalpindi, Pakistan in September 2020, when the graph of COVID-19 was flattening. Data was collected through a self-designed questionnaire for demographic details and DASS-21. The mean and standard deviation was calculated for depression, anxiety, and stress levels. Frequencies and percentages were calculated for the severity of DASS-21 and predisposing factors. Data analysis was done through SPSS. V. 25. Out of 157 students, there were 80(51%) males and 77 (49%) females. The mean age was 22.52 (SD=1.60). The overall mean score of anxiety was 7.43 ± 4.53, depression was 7.75 ± 4.12, and stress was 8.15 ± 4.53. This study found that the most common reason for stress and anxiety among students attending wards was the fear that they might infect their family members 42 (26.8%), followed by the fear of getting infected themselves 39 (24.8%). This study doesn’t exhibit a significant mental burden of grave concern however, the anxiety level was high among the Third year and depression level was high among Final year students. Fear of infecting family members and contracting the virus themselves were common reasons for distress.
