ABSTRACT

Introduction: Calciphylaxis, otherwise known as calcium uremic arteriolopathy, is defined as calcium deposition around blood vessels in skin and fat tissue which occurs in 1-4% of patients with end-stage renal disease (ESRD). Calcium deposition in the esophagus is extremely rare;to date, there have been only 4 cases reported worldwide. We report the fifth case of esophageal mucosal calcinosis occurring in a young male with ESRD. Case Description/Methods: A 37-year-old Thai man with ESRD on peritoneal dialysis since 2005 presented with generalized weakness and odynophagia due to oral ulcers, resulting in poor PO intake. He denied drinking alcohol, illicit drug use, or smoking. On exam his abdomen was soft, non-distended, non-tender, without any guarding. Past medical history included hypertension and COVID-19 in January 2022. Laboratory tests revealed neutropenia and pancytopenia, hyperphosphatemia, and hypocalcemia. EGD revealed distal esophageal esophagitis and hemorrhagic erosive gastropathy. Biopsy showed ulcerative esophagitis with dystrophic calcification, consistent with esophageal mucosal calcinosis .No intestinal metaplasia was noted. Immunohistochemistry was negative for CMV, HSV1, and HSV2. The patient was treated with pantoprazole 40mg IV every 12 hours, Magic Mouthwash 5ml qid, and Carafate 10mg qid. He was transferred to a cancer center where he had a bone marrow biopsy formed which was negative. His symptoms resolved and the patient was discharged to home (Figure). Discussion(s): Esophageal mucosal calcinosis is extremely rare. It is due to a combination of factors involving acidosis and the phenotypic differentiation (and apoptosis) of vascular smooth muscle cells (VSMC) into chondrocytes or osteoblast-like cells. These changes, along with the passive accumulation of calcium and phosphate, induce calcification. Acidosis is well-known to promote inflammation of the arterial walls, releasing cytokines that induce vascular calcification. The benefits of treatment with sodium thiosulfate remain unclear. An ample collection of cases should help devise standardized treatment options and establish management guidelines for this condition.

ABSTRACT

Background: Digital literacy has gained growing importance in the health agenda. However, the level of digital information use and access among Korean older adults is still low at 54%. It is important to understand digital literacy among older adults to provide healthcare and social connectivity, especially during the COVID-19 pandemic. Objective: This study aims to explore the digital literacy and identify barriers to learning and using digital devices among community-dwelling older adults in urban South Korea. Methods: A qualitative study was conducted using a semi-structured interview guide according to the DigComp 2.0 framework which emphasizes the competencies for full digital participation in five categories: information, communication, content creation, safety, and problem solving. Our sample consisted of 14 older adults (age 68 – 79, 12 women). Results: Participants reported varying competency of using digital devices for search, communication, and self-management of lifestyle and health. They actively sought help from family and community members to troubleshoot issues related to installation, maintenance, setup software or applications. However, they were passive or evasive in the use of digital devices because of concerns about invasion of privacy or personal information. They struggled to use digital devices owing to physical and cognitive changes associated with aging. Conclusion: Our findings depict current state and barriers of digital literacy in urban older adults in Korea.

ABSTRACT

Reduced amounts of aerosols blowing into the Yellow Sea (YS), owing to the temporary lockdown of factories in China during COVID-19, resulted in a 15% decrease in spring chlorophyll-a concentration (CHL) in March 2020 compared to its mean March values from 2003 to 2021. Particularly, the effect of land-based AOD is insignificant compared with that of atmospheric aerosols flowing into the YS, as indicated by the currents and wind directions. Hence, the main objective of this study was to understand the relationship between atmospheric aerosols and CHL by quantitatively considering relevant environmental changes using a Random Forest (RF) algorithm. Various input physical forcing variables to RF were employed, including aerosol optical depth (AOD), sea surface temperature (SST), mixed layer depth (MLD), wind divergence (WD), and total precipitation (TP). From the RF-based analysis, we estimated the relative contribution of each physical forcing variable to the difference in CHL during and after the COVID-19 lockdown period. The sensitivity of the RF model to changes in aerosol levels indicated positive effects of increased amounts of aerosols during spring blooms. Additionally, we calculated the quantitative contribution of aerosols to CHL changes. When SST was warmer and TP was lower than their climatology in March 2020, CHL increased by 0.22 mg m-3 and 0.02 mg m-3, respectively. Conversely, when MLD became shallower and AOD was lower than their climatology, CHL decreased as much as 0.01 mg m-3 and 0.20 mg m-3. Variations in WD caused no significant change in CHL. Overall, the specific estimations for reduced spring blooms were caused by a reduction in aerosols during the COVID-19 lockdown period. Furthermore, the RF developed in this study can be used to examine CHL changes and the relative role of significant environmental changes in biological blooms in the ocean for any normal year.

ABSTRACT

Public conspiracy beliefs prevent various social institutions including governments from communicating effectively. Fostering effective communication with high conspiracy belief individuals, who often disregard important public health messages, is crucial. This study investigated whether war framing could be used to effectively communicate with highly suspicious individuals. Specifically, it used an online experiment with 398 Korean citizens to examine how war-framing effects vary based on individual differences in general conspiracy and government-related conspiracy beliefs in the COVID-19 vaccination context. The results generally showed that literal messages were more effective for low conspiracy belief individuals while war-framed messages were more effective for those with high conspiracy beliefs. Additional analysis indicated that general conspiracy and government-related conspiracy beliefs were negatively associated with individuals’ vaccination attitudes and intentions. This study concludes by discussing the practical implications of its findings for health communication involving highly suspicious individuals. © 2022 SAGE Publications.

ABSTRACT

We examine whether the impacts of COVID-19 on labor supply differ across women with different degrees of childcare burden during the initial stage of the pandemic in South Korea. To identify the effect of the outbreak, we exploit the fact that the first wave of the outbreak in South Korea was concentrated in a specific region due to a largescale religious gathering. Utilizing the Local Area Labour Force Survey, we find that the negative impact was larger for women with young children than for women without young children. Specifically, our preferred specification suggests the employment rate of women with young children decreased by 3.9 percentage points more than that of women without young children due to the COVID-19 outbreak. Women with young children also reduced weekly working hours more than their counterparts without young children. Unlike women, the impacts of COVID-19 on the labor supply among men with and without young children were not different.

ABSTRACT

The inevitable shift towards online learning due to the emergence of the COVID-19 pandemic triggered a strong need to assess students using shorter exams whilst ensuring reliability. This study explores a data-centric approach that utilizes feature importance to select a discriminative subset of questions from the original exam. Furthermore, the discriminative question subset’s ability to approximate the students exam scores is evaluated by measuring the prediction accuracy and by quantifying the error interval of the prediction. The approach was evaluated using two real-world exam datasets of the Scholastic Aptitude Test (SAT) and Exame Nacional do Ensino Médio (ENEM) exams, which consist of student response data and the corresponding the exam scores. The evaluation was conducted against randomized question subsets of sizes 10, 20, 30 and 50. The results show that our method estimates the full scores more accurately than a baseline model in most question sizes while maintaining a reasonable error interval. The encouraging evidence found in this paper provides support for the strong potential of the on-going study to provide a data-centric approach for exam size reduction. © 2021, Springer Nature Switzerland AG.

ABSTRACT

Smart irrigation is among the IoT smart farming practices deemed important in optimizing the ever-growing need for farm produce given the climate change and other farm produce affecting events e.g., COVID-19. In this paper we aim at enhancing the existing technology in smart farming by proposing some insight towards developing an easy-to-use tool. The tool helps irrigation farmers in making informed decisions on their water sprinkler placement for maintaining the recommended soil water moisture contents for their farm. Our framework notifies the farmer when the sprinklers rearrangement is due based on the farm's soil moisture level readings. Our work defines the optimal computational parameter values for the strategic sprinkler deployment and introduces the required instruments and set up procedure. We demonstrate the implementation and user-friendly output of the apparatus with a display showing the actionable soil moisture information. Such results will provide the very critical information needed by a smart irrigation farmer to make informed decisions about their farm based on its soil water moisture contents.

ABSTRACT

The unprecedented COVID-19 pandemic at the beginning of 2020 jeopardized the entire world. Meanwhile, the Russia–Saudi Arabia oil war led a crude oil market going out of the frying pan into the fire. This research has two main purposes. First, we investigate structures of the crude oil related exchange-traded products (ETPs) in terms of operation and cost. Second, we analyze the correlation and investment performance of the crude oil related ETPs and West Texas Intermediate spot market. The major findings are as follows: (1) there is a positive correlation between the crude oil spot and the crude oil producing firm, (2) the investment performance of the crude oil related ETPs is inferior to that of the crude oil spot due to the rollover cost, (3) the investment performance of the crude oil related leverage ETNs (Exchange-Traded Notes) or inverse ETPs has deteriorated because their managing structure tracks the daily return which leads to the compounding effects. These empirical results show the characteristics of the gain and loss of the crude oil-related ETPs, which enhance conceptual understanding and offer implications to policymakers and authorities for the efficiency of the alternative investment strategy. © 2021, Korean Securities Association.

ABSTRACT

TOPIC: Chest Infections TYPE: Medical Student/Resident Case Reports INTRODUCTION: As the COVID-19 pandemic progresses, genetic variants have been identified globally, including the UK, South Africa, and Brazil strains. These variants exhibit genetic mutations in spike proteins and open reading frame regions. Rising cases of COVID-19 strains call to question the accuracy of current polymerase chain reaction (PCR) testing in detecting genetic variants. CASE PRESENTATION: A 76-year-old male nursing home resident was brought to the emergency department (ED) by ambulance due to progressively worsening dyspnea. His past medical history was remarkable for COPD and diabetes mellitus type II. On initial presentation, his respiratory rate was 30 breaths per minute, heart rate was 128 beats per minute, blood pressure was 135/64 mmHg, and oxygen saturation was 92% on supplemental oxygen via bilevel positive airway pressure (BIPAP). Physical exam was remarkable for bilateral rhonchi with accessory muscle use. Labs were remarkable for a white blood cell count of 16.5 109/L with lymphopenia, lactic acid of 2.2 mmol/L, and a d-dimer of 5250 ng/mL. Chest CT showed bilateral patchy ground glass infiltrates, fibrotic changes, and small bilateral pleural effusions (Image 1). He tested negative for influenza A and B, Mycoplasma pneumoniae, Streptococcus pneumonia, and Legionella. Sputum cultures showed no growth. The patient tested negative for COVID-19 twice by RT-PCR analysis (Abbott Laboratory, Chicago, IL). He was treated with intravenous steroids and broad-spectrum antibiotics. He was unable to be weaned from BIPAP to a lower level of supplemental oxygen. Eight days after hospital admission, the patient tested positive for COVID-19 IgM and IgG antibodies. After 12 days of treatment, the patient suffered a fatal cardiac arrest. DISCUSSION: We present an elderly man with a clinical symptoms and imaging findings highly suggestive of COVID-19, despite multiple negative RT-PCR tests. The patient did not improve despite treatment with broad spectrum antibiotic and intravenous corticosteroids. Patients had positive COVID-19 IgM antibodies, despite no known recent prior infection. Although the lab utilized for COVID-19 RT-PCR analysis asserts that testing is not impacted by genetic variants, these cases challenge the true sensitivity of this testing in detecting emerging strains. CONCLUSIONS: There are potentially many patients in the community hospitals presenting with COVID-19 variants that are not detected by existing RT-PCR testing. The genetic diversity of COVID-19 may diminish the sensitivity of RT-PCR testing, as labs across the country utilize different primers and probes with variable sensitivities in detecting variants. Clinicians should maintain a high suspicion for COVID-19, despite negative PCR testing. REFERENCE #1: Wang R, Hozumi Y, Yin C, Wei G-W. Mutations on COVID-19 diagnostic targets.

ABSTRACT

Objective: The objectives of this study were to measure the global impact of the pandemic on the volumes for intravenous thrombolysis (IVT), IVT transfers, and stroke hospitalizations over 4 months at the height of the pandemic (March 1 to June 30, 2020) compared with two control 4-month periods. Background: The COVID-19 pandemic led to widespread repercussions on the delivery of health care worldwide. Design/Methods: We conducted a cross-sectional, observational, retrospective study across 6 continents, 70 countries, and 457 stroke centers. Diagnoses were identified by ICD-10 codes and/or classifications in stroke center databases. Results: There were 91,373 stroke admissions in the 4 months immediately before compared to 80,894 admissions during the pandemic months, representing an 11.5% (95%CI,-11.7 to-11.3, p<0.0001) decline. There were 13,334 IVT therapies in the 4 months preceding compared to 11,570 procedures during the pandemic, representing a 13.2% (95%CI,-13.8 to-12.7, p<0.0001) drop. Interfacility IVT transfers decreased from 1,337 to 1,178, or an 11.9% decrease (95%CI,-13.7 to-10.3, p=0.001). There were greater declines in primary compared to comprehensive stroke centers (CSC) for stroke hospitalizations (-17.3% vs-10.3%, p<0.0001) and IVT (-15.5% vs-12.6%, p=0.0001). Recovery of stroke hospitalization volume (9.5%, 95%CI 9.2-9.8, p<0.0001) was noted over the two later (May, June) versus the two earlier (March, April) months of the pandemic, with greater recovery in hospitals with lower COVID-19 hospitalization volume, high volume stroke center, and CSC. There was a 1.48% stroke rate across 119,967 COVID-19 hospitalizations. SARS-CoV-2 infection was noted in 3.3% (1,722/52,026) of all stroke admissions. Conclusions: The COVID-19 pandemic was associated with a global decline in the volume of stroke hospitalizations, IVT, and interfacility IVT transfers. Primary stroke centers and centers with higher COVID19 inpatient volumes experienced steeper declines. Recovery of stroke hospitalization was noted in the later pandemic months, with greater recovery in hospitals with lower COVID-19 hospitalizations, high volume stroke centers, and CSCs.

ABSTRACT

Problem Statement: A newly discovered infectious disease, known as COVID-19, has spread across the world with alarming speed. This resulted in shifting from face-to-face to online instruction and provoking stress and anxiety for many physical education teachers. Purpose: Grounded in transformative learning theory, we examined physical education teachers’ perceptions and experiences online teaching during the COVID-19 pandemic. Method: The participants in the present study consisted of four male and four female teachers who were all certified in teaching PE from several different regions of the United States. A semi-structured interview was employed. Five participants teach at the public elementary school and three participants teach at the public middle school. The following questions guided this study: (a) what are the perceptions of physical education teachers when they are requested online teaching?;(b) what are the experiences of physical education teachers when transitioning from face-to-face physical education to online teaching? and;(c) Did your perspectives change after online teaching? The data were analyzed by open, axial, and selective coding. Results: The following themes emerged from the analysis: (a) Not excited about online teaching: Lack of technological knowledge;(b) Benefits and challenges of online teaching;(c) Main goal: engage in physical activity;(d) Marginalization: physical education is not valued and;(e) Longing for face-to-face physical education. Conclusions: The findings of the current study showed that participants expressed unfavorable perceptions of online teaching during the COVID-19 pandemic. The results of this study revealed that all of the participants looked forward to teaching face-to-face physical education because they missed in-person relationships and interactions with their students. © 2021, Editura Universitatii din Pitesti.

ABSTRACT

IntroductionCOVID-19, was declared a pandemic by World Health Organisation on March 11, 2020. Older people with dementia or those with multimorbidity are more vulnerable to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the development of COVID-19. Given absence of a vaccine or treatment, prevention is the fundamental aspect of COVID-19 control. This requires early identification of contagious people with COVID-19 and isolation keeping them apart from non infected group of people. Early identification of infection in elderly with dementia or functional psychiatric condition is often difficult, due to difficulty in obtaining history or evaluating medical symptoms.Objectives1) To establish the current standards of interventions provided at the unit to control COVID-19, with current recommendation by Government guidance. 2) To address difficulties in early identification of people of COVID-19 in Old Age Psychiatry wards. 3) To introduce sustainable interventions aimed at controlling COVID-19 risk, targeted to this group.MethodsTrust guidance for COVID-19 testing on the ward and guidance of isolation were reviewed. Literature review of currently available scientific evidence for testing for controlling COVID-19 was conducted.ResultsWe have created a bi-weekly mass testing guidance for Old Age Psychiatry inpatient wards with clear guidane of when to start isolation and when to stop isolation.ConclusionsThere is no specific interventions to target older adult within our service currently and it was felt that it is necessary to develop a sustainable mass testing programme for this group of people for control of COVID-19.

ABSTRACT

Background: Since the COVID-19 pandemic began in early 2020, there have been many reports that it has had a significant impact on screening, case identification and referral in cancer diagnosis. We investigated the diagnostic and therapeutic status of breast malignancy before and after the COVID-19 pandemic at the multi-institution level. Methods: We have reviewed the records of patients with breast cancer from February 2019 to July 2020 in six university hospitals in Korea. The patients were divided into two groups according to the initial date of cancer diagnosis: Period A, from February to April and Period B, from May to July in 2020. The two groups were compared for the same periods in 2019. The goals were to determine whether breast cancer screening and diagnosis have been delayed and thus resulted in stage migration. We also examined the difference in the number of surgeries in patients diagnosed with breast cancer during those periods. Results: The total of 1,669 breast malignancy diagnosis was made in the grouped periods of 2019, and 1,369 diagnoses in 2020. All patients were screened by PCR test for COVID-19 prior to hospitalization, and none of them tested positive. Overall, there was a 9.9% reduction in the number of diagnoses than in 2019 and the decrease was more significant in Period A (11.1% vs. 8.7%). According to the age, there was no difference until the 30s but decreased from those in their 40s and above. The decline was more pronounced in the elderly. The COVID-19 pandemic has affected breast cancer screening (decreased by 27.4%) and more diminished in Period A (41.0% vs. 19.0%). Invasive breast cancer stage was not statistically different in Period A compare with 2019 (p = 0.170). But the stage in Period B was different (p = 0.032), and more patients were observed in advanced stages in 2020. The decrease in surgery was noticeably observed in Period A (4.6%, from 480 to 438 surgeries) and not in Period B. The analysis of reconstruction surgery was similar. Conclusions: Patients with COVID-19 increased exponentially from late February in Korea. However, the number of patients per day decreased to less than 100 on March 15 and then flattened. The health care system for cancer was not overloaded and restrictions on visiting hospital were minimal. Analysis in the pandemic period of the 6-month showed that the number of breast cancer screening, diagnosis and surgeries decreased compared with the previous year. Those decreases were prominent in Period A when the COVID-19 patient surged. The upstage migration of breast cancer was generally insignificant but slightly occurred in Period B. The outbreak of infectious disease makes patients reluctant to come to the hospital, especially in the elderly. We need to discuss the potential long-lasting deleterious effect of the COVID-19 pandemic on cancer diagnosis and management. And we should prepare for how to deal with the backlog caused by the COVID-19 pandemic.

ABSTRACT

Introduction:Venous thromboembolism (VTE) is a leading cause of morbidity and mortality worldwide, with an annual incidence of 1 to 2 per 1000 per year in the US. Data support that this incidence is often secondary to thromboprophylaxis failure more than omission. Studies have demonstrated that an extensive pro-inflammatory and hypercoagulable state is present in COVID-19 patients, however the duration of this state post-infection is unclear. Early identification of additional risk factors for thromboprophylaxis failure warrants a closer follow up.Case Description:A 47-year-old man with obesity, recent COVID-19 pneumonia with ventilator dependent respiratory failure (VDRF) presents with one-day history of worsening abdominal pain and bloating due to pneumoperitoneum secondary to PEG tube placement 9 days prior. Patient was discharged after a prolonged admission for management of respiratory failure in the setting of COVID-19 infection that was complicated with severe hemodynamic compromising, subsequently managed with mechanical ventilation and V-V ECMO. Patient received DVT prophylaxis since admission. On presentation, patient was tachycardic in moderate respiratory distress and SpO2 of 94% on 75% FiO2. Further work-up revealed COVID PCR negative, elevated Ferritin of 1130 ng/mL, elevated NT-proB type Natriuretic peptide (NT-Pro BNP) of 467 pg/mL and elevated D-Dimer of 914 ng/mL. ABG revealed decreased PO2 and elevated A-a gradient. Computed tomography angiogram revealed moderate sized right upper lobe pulmonary embolism with no evidence of right heart strain. Patient was started on heparin drip.Discussion:The development of VTE despite prophylaxis is not uncommon. The rates of DVT in the absence of prophylaxis range between 40 and 60% and 2-5% in its presence. It is pertinent learning to identify high risk patients to develop VTE and consider anticoagulation at a higher dose or for a longer period of time even after discharge. Patients with COVID-19 infection possess and additional risk from the underlying hypercoagulable state and a worse outcome is expected. The high risk of thrombosis in COVID-19 is demonstrated by the increase in d-dimer, which was found to be the most significant change in coagulation parameters in these group, suggesting increased thrombin production and activation of fibrinolysis. There is therefore a need to identify the increased risk of VTE at an early stage and to prevent thrombotic events and organ damage as far as possible. More data is needed on how long this hypercoagulability period persist, but definite steps need to be taken to address this common complication in this special population.

ABSTRACT

The COVID-19 pandemic markedly changed the human shopping nature, necessitating a contactless shopping system to curb the spread of the contagious disease efficiently. Consequently, a customer opts for a store where it is possible to avoid physical contacts and shorten the shopping process with extended services such as personalized product recommendations. Automatic age and gender estimation of a customer in a smart store strongly benefit the consumer by providing personalized advertisement and product recommendation;similarly, it aids the smart store proprietor to promote sales and develop an inventory perpetually for the future retail. In our paper, we propose a deep learning-founded enterprise solution for smart store customer relationship management (CRM), which allows us to predict the age and gender from a customer’s face image taken in an unconstrained environment to facilitate the smart store’s extended services, as it is expected for a modern venture. For the age estimation problem, we mitigate the data sparsity problem of the large public IMDB-WIKI dataset by image enhancement from another dataset and perform data augmentation as required. We handle our classification tasks utilizing an empirically leading pre-trained convolutional neural network (CNN), the VGG-16 network, and incorporate batch normalization. Especially, the age estimation task is posed as a deep classification problem followed by a multinomial logistic regression first-moment refinement. We validate our system for two standard benchmarks, one for each task, and demonstrate state-of-the-art performance for both real age and gender estimation. © 2021 by the authors.

ABSTRACT

A park has a variety of attributes, providing beautiful natural scenery and a place to rest as well as a cultural space in which performances and events are held. This study aimed to examine the various destination attributes that a place has, specifically, the resources of an urban park, by profiling visitors according to these destination attributes. The study setting, Gwanggyo Lake Park (GLP), is located in Suwon City and is in the limelight as an eco-friendly leisure and tourism destination in South Korea. As a result of profiling 595 visitors through an application of Latent Profile Analysis (LPA), three types of profiles were obtained: “Relaxation Leisure Seekers (RLS),” “Nature Environment Seekers (NES),” and “Ecological Experience Seekers (EES).” There were differences by type in visiting patterns, environmental propensity, distance from residence, and income. The results allow a better understanding of the various attributes of the park as an ecological tourism destination by visitor profile and profile-specific characteristics. Due to COVID-19, more people are visiting parks, which are natural outdoor spaces. This study provides implications for both theoretical and practical aspects of natural resource management in that it profiles visitors by highlighting parks as both leisure and tourism destinations. © 2021 by the authors.

ABSTRACT

Objectives: The objective of this presentation is to implement and evaluate a yoga-based psychoeducation program in a school setting. Methods: The program consisted of a 35-minute session once weekly for 8 weeks. Each session introduced a psychosocial theme, breathing exercises, yoga poses, and relaxation techniques. Both sites had the same instructor and program, and ran from January to March 2020. Multiple measures of mental health were completed before and after the program. Results: A total of 33 students from 2 high schools participated. Of those, 29 students (88%) participated in at least 6 sessions, and all (100%) participated in at least 5 of 8 sessions. The mean age was 14.8 ± 0.8 years. Nineteen (57.6%) were female, and 14 (42.4%) were male. Seventeen (51.5%) were Asian, 5 (15.2%) were White, 3 (9.1%) were Hispanic/Latinx, 4 (12.1%) identified as other, and 4 (12.1%) were unknown. Of the 29 survey respondents, 28 (96.6%) responded that the program helped their psychosocial problems. The Outcomes Rating Score (ORS) showed no significant differences before the program (M = 29.0, SD = 7.8) compared to after the program (M = 28.9, SD = 5.6 [t = 0.03;p = 0.49]). The Child and Youth Resilience Measure (CYRM) also showed no difference before the program (M = 72.6, SD = 9.8) compared to after the program (M = 72.9, SD = 9.9 [t = –0.097;p = 0.46]). In addition, the Strength and Difficulties Questionnaire (SDQ) showed no differences from pre- (M = 9.2, SD = 4.6) to postprogram (M = 10.1, SD = 6.2 [t = –0.49;p = 0.32]). Controlling for sex and ethnicity did not change the results for all 3 measures. Conclusions: This study demonstrated the feasibility of implementing a yoga-based psychoeducation program in schools with positive student feedback. However, there were no significant differences in outcome measures before and after the program. The discrepancy between the participants’ feedback and the lack of significant changes in outcome measures may be attributable to a couple factors, including the possible impact of COVID-19 and the participant group being a healthy population. For future studies, we recommend a larger sample size with a control group. We also recommend considering repeating the program with a clinical population with a screening process or using measures more specific for healthy populations. CAM, SC, WL
