Health Belief Model Factors and Personal Characteristics Associated With COVID-19 Vaccination Behaviors in Adults.

Prior studies have mainly examined factors regarding COVID-19 vaccination intentions. This study investigated the factors associated with COVID-19 vaccination behaviors in Korean adults. A total of 620 adults recruited from a survey company between July and August 2021 completed an online survey asking about their personal characteristics, health beliefs, and COVID-19 vaccination status. The collected data were analyzed using descriptive statistics, Pearson's χ2 test, independent-samples t test, and logistic regression analysis. Less than half the participants received COVID-19 vaccinations, whereas 56.3% did not. The full regression model explained 33.3% of the variance in COVID-19 vaccination status. Age older than 60 years, perception of feeling healthy, presence of chronic diseases, past flu shot experiences, and five health belief model factors were significant factors associated with COVID-19 vaccination behaviors. COVID-19 vaccination intention was the most closely related factor (odds ratio, 12.37; 95% confidence interval, 3.54-43.26; P < .001). Vaccinated participants were more likely than unvaccinated to perceive susceptibility to COVID-19 infection, benefits, self-efficacy, moral responsibility, and subjective norms regarding COVID-19 vaccination. Based on the results, vaccinated and unvaccinated individuals showed different attitudes toward COVID-19 infection and vaccination. This study suggests that COVID-19 vaccination intentions lead to actual vaccination behavior.

Idiopathic systemic capillary leak syndrome: a case report.

BACKGROUND: Idiopathic systemic capillary leak syndrome (ISCLS) is a rare disease characterized by recurrent episodes of acute life-threatening attacks of shock, hemoconcentration, and hypoalbuminemia. Increase in capillary permeability results in reversible plasma movement into the interstitial spaces followed by appearance of related symptoms or complications, including renal failure. This condition can be potentially life-threatening; however, it is easily misdiagnosed. CASE PRESENTATION: A 47-year-old man with no previous medical history presented to the emergency department after experiencing general weakness and abdominal pain. He developed hypovolemic shock within 3 h of presentation and initial laboratory tests showed hemoconcentration, hypoalbuminemia and acute kidney injury. Following vigorous fluid therapy and supportive care, the patient recovered, but a similar episode recurred after 4 months without any specific trigger. Based on the combined clinical manifestations and laboratory findings of both the attacks, he was diagnosed with ISCLS. Symptomatic relief was achieved via oxygen supplementation and massive volume replacement using normal saline and the patient was prescribed bambuterol 10 mg and theophylline 400 mg once-a-day. He was discharged from the hospital on day 5 of hospitalization. Thereafter, the patient has been followed for 5 years without any symptoms or recurrence of ISCLS even in the situation of COVID-19 infection. CONCLUSIONS: ISCLS is an extremely infrequent and commonly misdiagnosed disease. However, early diagnosis, treatment and prophylaxis through accumulated clinical data can prevent ISCLS recurrence and the development of related fatal complications. Therefore, clinicians need to be well aware of the variety of clinical characteristics and treatment options of this disease.

Impact of COVID-19 infection on sports performance of elite university athletes.

BACKGROUND: Cardiopulmonary functions of athletes can be affected by the Coronavirus disease 2019 (COVID-19). This study aimed to investigate athletes' pattern of returning to sports after COVID-19, their experience of COVID-19-associated symptoms, and the disturbance in sports performance caused by the symptoms. METHODS: Elite university athletes who were infected with COVID-19 in 2022 were recruited for the survey and the data for 226 respondents were analyzed. Information about COVID-19 infection and the degree of disturbance in ordinary training and competition was collected. Their returning pattern to sports, the prevalence of COVID-19 symptoms, the degree of disturbance in sports by related symptoms, and factors associated with disturbance in sports and fatigue were analyzed. RESULTS: Results showed that 53.5% of the analyzed athletes returned to ordinary training immediately after quarantine, while 61.5% experienced disturbance in ordinary training, and 30.9% experienced that in competition. Most prevalent COVID-19 symptoms were lack of energy, easy fatiguability and cough. Disturbance in ordinary training and competition were mainly related to generalized, cardiologic, and respiratory symptoms. Women and those with severe and generalized symptoms had significantly higher odds of experiencing disturbance in training. Those with cognitive symptoms had higher odds of being "fatigue case." CONCLUSIONS: More than half of the athletes returned immediately to sports after the legal quarantine period of COVID-19 infection and experienced disturbance in ordinary training by related symptoms. Prevalent COVID-19 symptoms and the associated factors causing disturbance in sports and fatigue case were also revealed. This study will be helpful to establish the safe return guidelines essential for athletes after COVID-19.

The Experience of Patient Safety Error for Nursing Students in COVID-19: Focusing on King's Conceptual System Theory.

Some nursing students experience errors related to patient safety, such as falls, medication administration errors, and patient identification errors during clinical practice. However, only a few nursing students report errors during clinical practice. Accordingly, the present study aimed to investigate patient safety errors that nursing students experience during clinical practice in the context of the COVID-19 pandemic. This study conducted in-depth interviews with 14 candidates for graduation from the Department of Nursing at a university in South Korea. In addition, after transcribing the collected data, a directed content analysis for the data based on King's interacting system theory was performed. As a result, four core categories were identified: (i) nursing students' perception of patient safety error occurrence, (ii) interaction between nursing students and others, (iii) interaction between nursing students and organizations, and (iv) nursing students' training needs related to patient safety errors. Consequently, this study identified the patient safety error-related experiences of nursing students during clinical practice during the COVID-19 pandemic. The results suggest that in the future, nursing education institutions must establish a system for nursing students to report patient safety errors during clinical practice for patient safety education and develop practical and targeted education strategies in cooperation with practice training hospitals.

Chest CT Findings of COVID-19 Patients with Mild Clinical Symptoms at a Single Hospital in Korea.

Purpose: To retrospectively evaluate the chest computed tomography (CT) findings of coronavirus disease 2019 (COVID-19) in patients with mild clinical symptoms at a single hospital in South Korea. Materials and Methods: CT scans of 87 COVID-19 patients [43 men and 44 women; median age: 41 years (interquartile range: 26.1-51.0 years)] with mild clinical symptoms (fever < 38℃ and no dyspnea) were evaluated. Results: CT findings were normal in 39 (44.8%) and abnormal in 48 (55.2%) patients. Among the 48 patients with lung opacities, 17 (35.4%) had unilateral disease and 31 (64.6%) had bilateral disease. One (2.1%) patient showed subpleural distribution, 9 (18.8%) showed peribronchovascular distribution, and 38 (79.2%) showed subpleural and peribronchovascular distributions. Twenty-two (45.8%) patients had pure ground-glass opacities (GGOs) with no consolidation, 17 (35.4%) had mixed opacities dominated by GGOs, and 9 (18.8%) had mixed opacities dominated by consolidation. No patients demonstrated consolidation without GGOs. Conclusion: The most common CT finding of COVID-19 in patients with mild clinical symptoms was bilateral multiple GGO-dominant lesions with subpleural and peribronchovascular distribution and lower lung predilection. The initial chest CT of almost half of COVID-19 patients with mild clinical symptoms showed no lung parenchymal lesions. Compared to relatively severe cases, mild cases were more likely to manifest as unilateral disease with pure GGOs or GGO-dominant mixed opacities and less likely to show air bronchogram.

Onset of various CNS inflammatory demyelination diseases following COVID-19 vaccinations.

BACKGROUND: Since the start of COVID-19 vaccination worldwide, there have been several reports of inflammatory demyelinating diseases of the central nervous system (CNS-IDDs) following vaccination. METHODS: We prospectively collected cases of new-onset CNS-IDDs with a temporal relationship between disease onset and COVID-19 vaccination and investigated their proportion among newly registered cases of CNS-IDD over the past year. RESULTS: Among 117 cases, 10 (8.5%) had their first disease manifestation within one month following COVID-19 vaccination: 2 multiple sclerosis, 2 neuromyelitis optica spectrum disorder, 3 MOG antibody-associated disease, and 3 unclassified CNS-IDDs. CONCLUSION: This observation suggests that COVID-19 vaccination may trigger the onset of various CNS-IDDs in susceptible individuals.

Development and Evaluation of a Preceptor Education Program Based on the One-Minute Preceptor Model: Participatory Action Research.

This participatory action research study was conducted to confirm the implementation process and effect of developing and applying a preceptor education program based on the One-Minute Preceptor Model to foster the competence of preceptor clinical nurses. The study was conducted for eight weeks from March 2020 on 30 preceptor nurses in South Korea. Nursing standards were developed for two weeks and six cycles (comprising four stages) were performed. Data collection was integrated using both quantitative and qualitative approaches. For quantitative data, the Clinical Core Competency of Preceptor (CCCP) and General Communication Competence Scale (GICC-15) results were collected from preceptor nurses through questionnaires. Reflection journals of nurses' experiences were also analyzed through content analysis and frequency of keywords using WordClouds. There was no significant change in CCCP or GICC-15 results among preceptor nurses. However, nurses' experiences were associated with the growth and development of competencies such as evidence-based practice, quality feedback, and self-reflection. The program was effective in developing nurse competencies. Therefore, it is necessary to encourage One-Minute Preceptor Model activities among preceptors through an action research approach and to actively support research and practice in clinical settings, as well as to provide organizational and systematic support.

Effects of Government-Driven Smartphone Text Messages on Public Compliance With COVID-19 Preventative Measures.

The new pandemic situation caused by a highly infectious virus has prompted the government of many countries to strengthen epidemic prevention measures. An unprecedented action was taken by the Korean government by sending text messages on COVID-19 preventative measures and the movement routes of confirmed-positive persons to the entire nation's smartphones. This study aimed to examine how effective the government-driven smartphone text messages were for public compliance with the measures. A total of 489 participants completed an online questionnaire or a pencil-and-paper questionnaire between September and October 2020. A self-reported questionnaire was used to measure the degree of compliance with the measures, the perceptions of the role of smartphone text messages in compliance with the measures, and the overall feelings toward smartphone text messages. The data were analyzed using descriptive statistics and two-way analysis of variance. The written responses were grouped by meaning. The participants presented a high degree of compliance with the measures and perceived the importance of the role of continuous smartphone text messages in complying with the measures. Positive feelings toward smartphone text messages predominated over negative feelings. Using smartphone text messages in nursing practice is recommended for patients requiring the continuous management of their disease.

Nurses' Adaptations in Caring for COVID-19 Patients: A Grounded Theory Study.

As the novel coronavirus (COVID-19) pandemic continues, frontline nurses caring for COVID-19 patients are experiencing severe fatigue and mental stress. This study explored nurses' adaptation process in caring for COVID-19 patients and examined how nurses interact with the phenomenon using a grounded theory approach. The study aimed to develop a substantive theory and provide basic data with which to develop intervention programs that can support nurses caring for COVID-19 patients. Data were collected between 7 August and 31 October 2020, via face-to-face in-depth interviews with 23 nurses who had been caring for COVID-19 patients for six months or more at a nationally designated COVID-19 hospital. Sampling was started purposively and continued theoretically. Data analysis, performed using the method proposed by Strauss and Corbin, resulted in 13 main categories, the core one being "growing as a proficient nurse alongside comrades on the COVID-19 frontline". The study's results identify the nurses' adaptation process in caring for COVID-19 patients and their reactions to the circumstances around it. Ensuring that nurses can systematically cope with emerging infectious diseases requires regularly providing them with basic education on caring for patients with such diseases and strengthening professional education in order to develop nurses specializing in them. This study also recommends that a support system for work and childrearing be developed.

Development and Effects of Leukemia Nursing Simulation Based on Clinical Reasoning.

While the effects of simulation education and the importance of the clinical reasoning process have been well-reported, an acute myelocytic leukemia (AML) patient-care simulation program has yet to be formulated exclusively for the clinical experience of students. This study developed and subsequently applied a simulation program based on clinical reasoning for AML to improve the learning outcomes and describe the learning experience for nursing students. Following a mixed-methods framework, the program's effects on students' knowledge were quantitatively measured, while their learning experience was qualitatively measured using self-reflection through journal writing. Differences in the pre- and post-scores between the experimental and control groups were statistically significant for theoretical knowledge and clinical performance. In addition, content analysis of both groups' journals revealed three themes: (1) transformation into a self-directed learner for understanding the clinical situation, (2) increased awareness of clinical reasoning ability, and (3) embodiment of the clinical reasoning process. Standardizing the developed program's scenarios prompted the participants' compliance and engagement, and effectively achieved the learning outcomes. This simulation program aided the assessment of nursing intervention's effectiveness and suggested objective criteria according to clinical reasoning. Similar programs involving other clinical cases, not exclusive to leukemia, should be developed and evaluated.

Factors Associated with Worsening Oxygenation in Patients with Non-severe COVID-19 Pneumonia.

BACKGROUND: This study aimed to determine the parameters for worsening oxygenation in non-severe coronavirus disease 2019 (COVID-19) pneumonia. METHODS: This retrospective cohort study included cases of confirmed COVID-19 pneumonia in a public hospital in South Korea. The worsening oxygenation group was defined as that with SpO2 ≤94% or received oxygen or mechanical ventilation (MV) throughout the clinical course versus the non-worsening oxygenation group that did not experience any respiratory event. Parameters were compared, and the extent of viral pneumonia from an initial chest computed tomography (CT) was calculated using artificial intelligence (AI) and measured visually by a radiologist. RESULTS: We included 136 patients, with 32 (23.5%) patients in the worsening oxygenation group; of whom, two needed MV and one died. Initial vital signs and duration of symptoms showed no difference between the two groups; however, univariate logistic regression analysis revealed that a variety of parameters on admission were associated with an increased risk of a desaturation event. A subset of patients was studied to eliminate potential bias, that ferritin ≥280 µg/L (p=0.029), lactate dehydrogenase ≥240 U/L (p=0.029), pneumonia volume (p=0.021), and extent (p=0.030) by AI, and visual severity scores (p=0.042) were the predictive parameters for worsening oxygenation in a sex-, age-, and comorbid illness-matched case-control study using propensity score (n=52). CONCLUSION: Our study suggests that initial CT evaluated by AI or visual severity scoring as well as serum markers of inflammation on admission are significantly associated with worsening oxygenation in this COVID-19 pneumonia cohort.

Clinical Experience with Use of Remdesivir in the Treatment of Severe Acute Respiratory Syndrome Coronavirus 2: a Case Series.

BACKGROUND: A novel antiviral agent, remdesivir (RDV), is a promising candidate treatment for coronavirus disease 2019 (COVID-19) in the absence of any proven therapy. MATERIALS AND METHODS: This retrospective case series included 10 patients with a clinically and laboratory confirmed diagnosis of severe COVID-19 pneumonia who had received RDV for 5 days (n = 5) or 10 days (n = 5) in the Phase III clinical trial of RDV (GS-US-540-5773) conducted by Gilead Sciences. The clinical and laboratory data for these patients were extracted. RESULTS: One patient in the 10-day group received RDV for only 5 days because of nausea and elevated liver transaminases. No patient had respiratory comorbidity. Seven patients had bilateral lesions and three had unilateral lesions on imaging. All patients had received other medications for COVID-19, including lopinavir/ritonavir and hydroxychloroquine, before administration of RDV. Five patients required supplemental oxygen and one required mechanical ventilation. All patients showed clinical and laboratory evidence of improvement. Half of the patients developed elevated liver transaminases and three had nausea. There were no adverse events exceeding grade 2. CONCLUSION: Our experience indicates that RDV could be a therapeutic option for COVID-19. A well-designed randomized controlled clinical trial is now needed to confirm the efficacy of RDV in patients with COVID-19.

Four cases of coronavirus disease 2019 in the early stage of pandemic of South Korea: a single public hospital experience.

In view of this pandemic, as of February 2020, South Korea has the second highest number of confirmed cases in the world. Herein, we report four confirmed coronavirus disease 2019 (COVID-19) cases in the early stage of the pandemic in South Korea and describe the identification, diagnosis, clinical course, and management, including one patient's initial mild symptoms at presentation and their progression to pneumonia on day 21 of illness. Within 48 hours of hospitalization, all four patients underwent evaluation for initial laboratory parameters, COVID-19 polymerase chain reaction (PCR), and chest computed tomography (CT) findings. All four mild COVID-19 patients were discharged, and they were re-examined 14 days after discharge. Despite all four of them being asymptomatic, one patient was re-admitted after confirmation of COVID-19 through PCR viral nucleic acid detection. She could be discharged after 7 days with two subsequent negative COVID-19 PCR at 24-hour intervals. Patients with mild COVID-19 generally have normal follow-up chest CT scans after discharge, even if the early chest CT definitely indicates pneumonia. Re-hospitalized patients with COVID-19 PCR positive results after discharge were not related to her initial chest CT, lab, symptoms compared other three patients.
