ABSTRACT

Purpose@#To report the first domestic case of orbital eccrine hidrocystoma.Case summary: A 40-year-old man visited our clinic after an orbital mass was discovered in the left eye. Orbital magnetic resonance imaging showed a well-defined 1 cm mass on the superomedial side of the orbit, slightly posterior to the globe. The mass was excised completely without rupture through an incision to the upper eyelid skin. The mass appeared more like a cyst than a hemangioma. The diagnosis of eccrine hidrocystoma was confirmed histopathologically. The patient recovered and there was no recurrence at the 6-month follow-up. @*Conclusions@#Although orbital eccrine hidrocystoma is very rare, it should be included in the differential diagnosis of orbital tumors.

ABSTRACT

Objective@#This study investigated whether sleep and stress mutually interact to induce changes in white matter integrity. @*Methods@#Diffusion tensor imaging (DTI) was conducted on 36 participants (male=22, female=14; mean age=38.33±12.78 years). Participants were divided into three groups depending on their sleep quality and stress levels: poor sleepers with stress, poor sleepers without stress, and good sleepers. Sleep quality and stress level were evaluated using the Pittsburgh Sleep Quality Index and the Life Experiences Survey, respectively. Fractional anisotropy (FA) values were calculated employing DTI tractography. @*Results@#After controlling for age and sex, poor sleepers with stress exhibited a lower FA of the left inferior cerebellar peduncle (ICP) than did poor sleepers without stress (t=2.81, p=0.02). Poor sleepers without stress showed a higher FA of the right middle longitudinal fasciculus (MdLF) than did good sleepers (t=3.35, p=0.006). @*Conclusion@#The current study reports the effects of sleep, stress, and their interaction on the white matter integrities of the ICP and MdLF. ICP change seems to be associated with sleep disturbances related to stress, while MdLF change would be associated with sleep disturbances unrelated to stress.

ABSTRACT

Background@#Atopic dermatitis (AD) patients usually wonder if their condition will worsen after vaccination or if they should continue with the treatment they are receiving. Considering that many patients treated with dupilumab had previously experienced severe AD symptoms and flares, the concerns are more understandable. @*Objective@#This study aimed to investigate the safety of the coronavirus disease 2019 (COVID-19) vaccination in patients with AD treated with dupilumab. @*Methods@#We enrolled 133 patients (101 dupilumab-treated and 32 systemic oral agentstreated as control group) with AD from six hospitals. Patients were asked about worsening pruritus and AD (5-point Likert scale) after vaccination. AD variables (eczema area and severity index [EASI], investigator’s global assessment [IGA], itch numerical rating scale [NRS], sleep NRS, and patient-oriented eczema measure [POEM]) were compared pre- and postvaccination. Adverse reactions to the COVID-19 vaccination were observed. @*Results@#The incidence of adverse reactions to COVID-19 vaccines and worsening AD symptoms in dupilumab-treated patients were not significantly different compared with that in the control group. The itch NRS score increased significantly after vaccination (p<0.001).However, there were no statistically significant differences between the pre-and post-EASI, IGA, and POEM scores. Eight patients (7.9%) had worse EASI scores and required rescue therapy; however, most were easily managed with low-dose steroids or topical agents. None of the patients discontinued dupilumab treatment. @*Conclusion@#No serious adverse reactions were observed in patients with AD after COVID-19 vaccination. Exacerbation of pruritus and AD symptoms was observed but was mostly mild and transient.

ABSTRACT

Objective@#This study compared the treatment results of emergency department (ED) patients presenting with gingival bleeding, who were given dental consultations with those who were not. Also, the study compared patients presenting with gingival bleeding based on the period of availability of the dental consultation in the ED. @*Methods@#This was a retrospective study of patients with gingival bleeding visiting the ED from January 2011 to April 2020. The demographic data of patients, past medical history, etiology of bleeding, vital signs, lab findings, treatment methods, and disposition were analyzed. @*Results@#The mean level of hemoglobin was 13.3 g/dL in the group to whom dental consultation was made available, and 11.7 g/dL in the group not given dental consultation, which was a significant difference (P=0.010). Vitamin K injections were given to 1.9% of the former group and 6.2% of the latter group (P=0.049). Suturing was done in 14% of the former group and 1.2% of the latter (P<0.001). There were no significant differences between the two groups regarding admission to the ward or revisits to the ED. @*Conclusion@#Emergency physicians carried out conservative treatments for patients with gingival bleeding when dental consultation was unavailable. No differences in the treatment results were observed based on the length of time the dental consultation was made available.

ABSTRACT

Purpose@#This study aimed to develop and examine the validity and reliability of a self-efficacy scale for preventive health management related to premature labor (PHMSE-PL) for women of childbearing age. @*Methods@#Instrument development and validation were undertaken in three steps: conceptualization through a literature review and in-depth interviews, item generation and evaluation of content validity, and evaluation of construct validity and reliability. The content validity, factorial structure validity, and internal consistency reliability of the PHMSE-PL were evaluated, and cognitive interviewing was undertaken. Data were analyzed using confirmatory factor analyses, Cronbach's α, and 95% confidence intervals (CIs). @*Results@#The content validity was assessed by experts and was strengthened through cognitive interviews with women of childbearing age. The PHMSE-PL comprised 34 items across five factors. The construct validity of the PHMSE-PL was supported. Cronbach's α for the total scale was .97 (95% CI=.96-.97). @*Conclusion@#An evaluation of the psychometric properties of the PHMSE-PL scale found it to be a valid and reliable tool for women of childbearing age. The scale appears to be useful for women of childbearing age to self-assess their preventive health management self-efficacy related to premature labor and for health professionals to evaluate and promote women's preventive health management.

ABSTRACT

Background@#As the number of large-scale studies involving multiple organizations producing data has steadily increased, an integrated system for a common interoperable format is needed. In response to the coronavirus disease 2019 (COVID-19) pandemic, a number of global efforts are underway to develop vaccines and therapeutics. We are therefore observing an explosion in the proliferation of COVID-19 data, and interoperability is highly requested in multiple institutions participating simultaneously in COVID-19 pandemic research. @*Results@#In this study, a laboratory information management system (LIMS) approach has been adopted to systemically manage various COVID-19 non-clinical trial data, including mortality, clinical signs, body weight, body temperature, organ weights, viral titer (viral replication and viral RNA), and multiorgan histopathology, from multiple institutions based on a web interface. The main aim of the implemented system is to integrate, standardize, and organize data collected from laboratories in multiple institutes for COVID-19 non-clinical efficacy testings. Six animal biosafety level 3 institutions proved the feasibility of our system. Substantial benefits were shown by maximizing collaborative high-quality non-clinical research. @*Conclusions@#This LIMS platform can be used for future outbreaks, leading to accelerated medical product development through the systematic management of extensive data from non-clinical animal studies.

ABSTRACT

Objectives@#Our study aims to investigate the clinical and polysomnographic variables associated with subjective sleep perception. @*Methods@#Among the patients who underwent nocturnal polysomnography (PSG) at the Center for Sleep and Chronobiology of Seoul National University Hospital from May 2018 to July 2019, 109 diagnosed with insomnia disorder based on DSM-5 were recruited for the study, and their medical records were retrospectively analyzed. Self-report questionnaires about clinical characteristics including Pittsburgh sleep quality index (PSQI), Beck depression inventory (BDI), and Epworth sleepiness scale (ESS) were completed. Subjective sleep quality was measured using variables of subjective total sleep time (subjective TST), subjective sleep onset latency (subjective SOL), subjective number of awakenings, morning feeling after awakening, and sleep discrepancy (subjective TST–objective TST) the morning after PSG. Pearson and Spearman correlation analyses were used to determine the factors associated with subjective sleep perception. @*Results@#In patients with insomnia, subjective TST was negatively correlated with Wake After Sleep Onset (WASO) (p = 0.001) and N1 sleep (p = 0.039) parameters on polysomnography. Also, it was negatively correlated with PSQI (p < 0.001) and BDI (p = 0.014) scores. Sleep discrepancy was negatively correlated with PSQI score (p = 0.018). Morning feeling was negatively correlated with PSQI (p = 0.019) and BDI (p < 0.001) scores. @*Conclusion@#Our results demonstrated that subjective sleep perception is associated with PSG variables (WASO and N1 sleep) and with PSQI and BDI scores. In clinical practice, it is helpful to assess and manage insomnia patients in consideration of objective sleep variables, subjective sleep quality, and depressed mood, which can influence subjective sleep perception.

ABSTRACT

Background@#The coronavirus disease 2019 (COVID-19) pandemic has impacted various aspects of daily living and has influenced the life of every individual in a unique way.Acute myocardial infarction (AMI) is associated with high morbidity and mortality; thus, timely treatment is crucial to prevent poor prognosis. Therefore, an immediate emergency department (ED) visit is required; however, no domestic studies have reported the effect of COVID-19 on ED visits by patients with AMI. Therefore, this study aimed to assess the changes in the pattern of ED visits by patients with AMI by comparing visits during the COVID-19 outbreak period to those during two control periods. @*Methods@#This nationwide, retrospective study used registry data of the National Emergency Department Information System. The ‘outbreak period’ was defined as the period between February 21, 2020 and April 1, 2020, while the ‘control period’ was defined as the same time period in the preceding two years (2018 and 2019). The primary outcome of our study was the number of patients admitted to the ED owing to AMI during the outbreak and control periods. Secondary outcomes were time from symptom onset to ED visit, length of ED stay, and 30-day mortality following admission. @*Results@#During the outbreak period, 401,378 patients visited the ED; this number was lower than that during the control periods (2018: 577,548; 2019: 598,514). The number of patients with AMI visiting the ED was lower during the outbreak period (2,221) than during 2018 (2,437) and 2019 (2,591). @*Conclusion@#The COVID-19 pandemic has caused a reduction in ED visits by patients with AMI. We assume that this could likely be caused by misinterpretation of AMI symptoms as symptoms of respiratory infection, fear of contracting severe acute respiratory syndrome coronavirus 2, and restrictions in accessing emergency medical care owing to overburdened healthcare facilities. This study sheds light on the fact that healthcare and emergency medical staff members must work towards eliminating hurdles due to this pandemic for patients to receive timely emergency care, which in turn will help curb the growing burden of mortality.

ABSTRACT

This article aims to introduce the inception and operation of the COVID-19 International Collaborative Research Project, the world’s first coronavirus disease 2019 (COVID-19) open data project for research, along with its dataset and research method, and to discuss relevant considerations for collaborative research using nationwide real-world data (RWD). COVID-19 has spread across the world since early 2020, becoming a serious global health threat to life, safety, and social and economic activities. However, insufficient RWD from patients was available to help clinicians efficiently diagnose and treat patients with COVID-19, or to provide necessary information to the government for policy-making. Countries that saw a rapid surge of infections had to focus on leveraging medical professionals to treat patients, and the circumstances made it even more difficult to promptly use COVID-19 RWD. Against this backdrop, the Health Insurance Review and Assessment Service (HIRA) of Korea decided to open its COVID-19 RWD collected through Korea’s universal health insurance program, under the title of the COVID-19 International Collaborative Research Project. The dataset, consisting of 476 508 claim statements from 234 427 patients (7590 confirmed cases) and 18 691 318 claim statements of the same patients for the previous 3 years, was established and hosted on HIRA’s in-house server. Researchers who applied to participate in the project uploaded analysis code on the platform prepared by HIRA, and HIRA conducted the analysis and provided outcome values. As of November 2020, analyses have been completed for 129 research projects, which have been published or are in the process of being published in prestigious journals.

ABSTRACT

Background@#The objective of this article is to assess the mental health issues of the mild condition coronavirus disease 2019 (COVID-19) patients admitted to a community treatment center (CTC) in Korea. @*Methods@#A total of 107 patients admitted to a CTC were included as the study population, and their mental health problems including depression (patient health questionnaire-9), anxiety (generalized anxiety disorder scale-7), post-traumatic stress disorder (PTSD) (PTSD checklist-5) and somatic symptoms (by patient health questionnaire-15) were evaluated every week during their stay. The stigma related to COVID-19 infection was evaluated with an adjusted version of the Middle East respiratory syndrome (MERS) stigma scale. @*Results@#During the first week of isolation, the prevalence of more-than-moderate depression was 24.3%, more-than-moderate anxiety was 14.9%, more-than-moderate somatic symptoms was 36.5% and possible PTSD was 5.6% of total population. For depression and anxiety, previous psychiatric history and stigma of COVID-19 infection were significant risk factors. For PTSD, previous psychiatric history and stigma of COVID-19 infection as well as total duration of isolation were found to be significant risk factors. Prevalence of depression, anxiety and possible PTSD remained similar across the four weeks of observations, though the prevalence of severe depression, increased after four weeks of stay. Somatic symptoms seemed to decrease during their stay. @*Conclusion@#The results suggest that social mitigation of COVID-19 related stigma, as well as care of patients with pre-existing mental health problems are important mental health measures during this crisis period. It is also important that clinical guidelines and public health policies be well balanced over the protection of the public and those quarantined to minimize the negative psychosocial consequences from isolation of the patients.

ABSTRACT

In this paper, we reviewed domestic and foreign cases and evaluation methods for validation of sleep products for development of the domestic sleep industry. Foreign companies and organizations are trying to verify products relatively systematically for demonstration purposes, but they are using different methods depending on the institution, and standardized validation guidelines have not been established. In Korea, there has been little evaluation including objective verification for sleep products. Sleep-wake evaluation for validation of sleep products requires expert evaluation of the product and of the product effectiveness by users, and subjective and objective sleep-wake evaluations and circadian rhythm evaluation methods can be used. For more accurate verification, experimental designs such as randomization method, control product utilization method, and cross-experiment design can be used.

ABSTRACT

Purpose@#The purposes of this study were to describe the development and implementation of an interprofessional simulation-based education (IPSE) for undergraduate nursing and medical students, their perceptions of the impact of IPSE, and identify their changes in attitudes toward each other’s health professions after participating in IPSE in South Korea. @*Methods@#This study used a qualitative descriptive design. A purposive sample of 43 third-year medical students and a convenient sample of 44 fourth-year nursing students participated in a 2-day IPSE program that consisted of ice-breaking and patient safety activities, and 4-hour three interprofessional team-based high-fidelity simulation education sessions. Data were collected through reflective journal after the IPSE program and keywords before and after the IPSE program, and were analyzed using the content analysis and word cloud analysis. @*Results@#Three themes emerged: “positive experience” with understanding roles and responsibilities and learning by doing in simulation environments being reported. In the second theme, “positive learning outcomes” participants reported enhancing collaboration and confidence in communication skills. The final theme “benefits to patients of interprofessional collaborative practice” included high quality of care and patient safety. Before the IPSE experience, most medical students perceived the nurse as nightingale and syringe, and nursing students perceived the doctor as order, expert, and knowledge. After their IPSE experience, both nursing and medical students viewed each other as colleagues. @*Conclusion@#These results suggest that the use of high-fidelity team-based simulation in IPE is effective in practicing and developing undergraduate nursing and medical students’ interprofessional collaboration through hands-on experience.

ABSTRACT

Objective@#This study was performed to investigate the associations of life event stress with impulsivity, anxiety, and depressed mood as a function of the presence of a sleep disturbance. @*Methods@#In total, 214 participants (age 38.96±10.53 years; 111 females) completed self-report questionnaires, including the Life Experience Survey (LES), Pittsburgh Sleep Quality Index (PSQI), Barratt’s Impulsivity Scale (BIS), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI). The presence of a sleep disturbance was defined as a PSQI score >5. @*Results@#In total, 127 participants presented with a sleep disturbance (age 39.33±10.92 years; 64 females), whereas the remaining 87 did not (age 38.43±9.97 years; 47 females). Negative LES scores were significantly correlated with BIS (r=0.22, p=0.001), BAI (r=0.46, p< 0.001), and BDI (r=0.51, p<0.001) scores, and PSQI scores were significantly correlated with BAI (r=0.49, p<0.001) and BDI (r=0.60, p< 0.001) scores. Moderation analysis revealed statistically significant interactions between negative LES scores and the presence of a sleep disturbance on BIS (p=0.044) and BDI (p=0.014) but not on BAI (p=0.194) scores. @*Conclusion@#The findings of the present study suggest that life event stress has varying degrees of influence on mental health, especially impulsivity and depressed mood, depending on the presence or absence of a sleep disturbance.

ABSTRACT

Objectives@#. This study aimed to elucidate the patterns of upper airway collapse in obstructive sleep apnea (OSA) patients with a low body mass index (BMI). @*Methods@#. We designed and conducted a retrospective cohort study. Consecutive patients diagnosed with OSA who underwent drug-induced sleep endoscopy (DISE) were included. Patients were classified into four groups according to their BMI. Age, sex, and polysomnography data were investigated. The patterns of upper airway collapse were characterized by the structures involved (soft palate, tongue base, lateral pharyngeal wall, and epiglottis). We compared the patterns of upper airway collapse in the supine and lateral decubitus position among the four BMI groups using the chi-square test and multivariate binary logistic regression analysis. @*Results@#. A total of 627 patients (male, 517; mean age, 47.6±12.8 years) were included, consisting of 45, 79, 151, and 352 patients who were underweight or lower normal-weight (defined as the low BMI group), upper normal-weight, overweight, and obese, respectively. Severity indicators of OSA, such as the overall apnea-hypopnea index and duration of SaO2 below 90%, were significantly lower in patients with a low BMI than in obese patients, while their average oxygen saturation was significantly higher. The most common obstruction site in the supine position was the tongue base in patients with a low BMI (100%), whereas this obstruction site was significantly less common in obese patients (54.8%). Tongue base obstruction was mostly relieved in the lateral position, with no discernible obstruction in 86.7% of the low BMI patients. @*Conclusion@#. Airway obstruction in OSA patients with a low BMI is mostly due to tongue base obstruction, which improves in the lateral position. These characteristics should be kept in mind when considering treatment options for this subgroup of OSA patients.

ABSTRACT

This paper reviews the updated findings, including the current clinical guidelines and recent research trends, on the pathophysiology, diagnosis, and treatment of obstructive sleep apnea (OSA), a common sleep disorder associated with medical and mental disorders. The pathophysiology of OSA is believed to be related not only to the anatomical causes of the upper airway but also to the comparative anatomical mechanisms, such as the upper airway muscle function, arousal threshold, and loop gain. When OSA is suspected of being a clinical symptom or sign, a sleep study should be used for a diagnosis of OSA. Traditionally, continuous positive airway pressure has been the most effective first-line treatment for OSA. On the other hand, there could be a limitation of long-term compliance and new therapies that are suitable for the diverse mechanisms of OSA have been proposed or studied. In the future, the treatment of enhancing the effect through a more individualized consideration should be applied for OSA.

ABSTRACT

BACKGROUND: In cardiac arrest, the survival rate increases with the provision of bystander cardiopulmonary resuscitation (CPR), of which the initial response and treatment are critical. Telephone CPR is among the effective methods that might increase the provision of bystander CPR. This study aimed to describe and examine the improvement of neurological outcomes in individuals with out-of-hospital acute cardiac arrest by implementing the nationwide, standardized telephone CPR program. METHODS: Data from the emergency medical service-based cardiac arrest registry that were collected between 2009 and 2014 were used. The effectiveness of the intervention in the interrupted time-series study was determined via a segmented regression analysis, which showed the risk ratio and risk difference in good neurological outcomes before and after the intervention. RESULTS: Of 164,221 patients, 148,403 were analyzed. However, patients with unknown sex and limited data on treatment outcomes were excluded. Approximately 64.3% patients were men, with an average age of 63.7 years. The number of bystander CPR increased by 3.3 times (95% confidence interval [CI], 3.1–3.5) after the intervention, whereas the rate of good neurological outcomes increased by 2.6 times (95% CI, 2.3–2.9 [1.6%]; 1.4–1.7). The excess number was identified based on the differences between the observed and predicted trends. In total, 2,127 cases of out-of-hospital cardiac arrest (OHCA) after the intervention period received additional bystander CPR, and 339 cases of OHCA had good neurological outcomes. CONCLUSION: The nationwide implementation of the standardized telephone CPR program increased the number of bystander CPR and improved good neurological outcomes.
