Social jetlag and quality of life among nursing students during the COVID-19 pandemic: a cross-sectional study.

BACKGROUND: Amid drastic changes in the educational environment and continued substitution of in-person learning with online learning owing to the COVID-19 pandemic, it is important to analyze the predictors of quality of life among nursing students to devise strategies to enhance their quality of life. This study aimed to identify the predictors of nursing students' quality of life during the COVID-19 pandemic, focusing on social jetlag. METHODS: In this cross-sectional study, data were collected from 198 Korean nursing students in 2021, using an online survey. Chronotype, social jetlag, depression symptoms, and quality of life were assessed using the Korean version of the Morningness-Eveningness Questionnaire, Munich Chronotype Questionnaire, Center for Epidemiological Studies Depression Scale, and World Health Organization Quality of Life Scale abbreviated version, respectively. Multiple regression analyses were performed to identify the predictors of quality of life. RESULTS: Factors affecting participants' quality of life were age (ß = - 0.19, p = .003), subjective health status (ß = 0.21, p = .001), social jetlag (ß = - 0.17, p = .013), and depression symptoms (ß = - 0.33, p < .001). These variables accounted for 27.8% of the variance in quality of life. CONCLUSION: As the COVID-19 pandemic continues, the social jetlag of nursing students has decreased compared to before the pandemic. Nevertheless, the results showed that mental health issues such as depression affect their quality of life. Therefore, it is necessary to devise strategies to support students' ability to adapt to the rapidly changing educational environment and promote their mental and physical health.

Geographic Trends in Pediatric Psychotropic Medication Dispensing Before and After the Start of the COVID-19 Pandemic.

OBJECTIVE: This study examined trends and geographic variability in dispensing of prescription psychotropic medications to U.S. youths before and after the start of the COVID-19 pandemic. METHODS: Using national data on prescription medication dispensing, the authors performed a cross-sectional study examining the monthly percent change in psychotropic medications dispensed (total N=95,639,975) to youths (ages 5-18 years) in 2020 versus 2019, across medication classes and geographic regions. RESULTS: For many medications, more were dispensed in March 2020 than in March 2019 and fewer in April-May 2020 versus April-May 2019. Stimulants had the largest decline: -26.4% in May 2020 versus May 2019. The magnitude of the monthly percent change varied by region. CONCLUSIONS: Fewer psychotropic medications were dispensed to U.S. youths after the start of the COVID-19 pandemic compared with 2019. Although some medication classes rebounded to prepandemic dispensing levels by September 2020, dispensing varied by class and region.

Factors Affecting Fatigue among Nurses during the COVID-19 Pandemic.

This study identified clinical nurses' fatigue and related factors during the COVID-19 pandemic. This was a cross-sectional study. Data were collected from South Korean hospitals on 234 nurses' general characteristics, fatigue, depression, occupational stress, insomnia, and perceived daytime sleepiness using a structured questionnaire. The prevalence of fatigue was 62.0%, depression 52.1%, insomnia 20.7%, and daytime sleepiness 36.1%. Insomnia, sleepiness, depression, and occupational stress were significantly associated with fatigue. Ward nurses who cared for COVID-19 patients within the past month had significantly higher occupational stress related to organizational climate than those who had not provided care, and ICU nurses who cared for COVID-19 patients had significantly higher job insecurity-related occupational stress. Nurses have a high prevalence of fatigue and depression during the pandemic. Thus, insomnia, sleepiness, depression, and occupational stress must be reduced to lower nurses' fatigue. Caring for COVID-19 patients was not significantly associated with fatigue, but there were significant differences in occupational stress between nurses who provided such care and those who did not. Work environment-specific strategies are needed to reduce nurses' occupational stress during the pandemic.

Psychotropic Prescriptions During the COVID-19 Pandemic Among U.S. Children and Adolescents Receiving Mental Health Services.

Objective: Increased mental health problems among children and adolescents during the COVID-19 pandemic may have impacted psychotropic medication use. This study describes trends in monthly psychotropic medications before and early in the COVID-19 pandemic among 2- to 17-year-old children and adolescents with mental health disorders. Methods: A cross-sectional study design using the 2019-2020 IQVIA™ prescription and medical commercial claims data to estimate the proportion of children and adolescents with any psychotropic prescription in the month out of all with any mental health-related medical or prescription services in the month and the year-over-year percent change. We assessed monthly proportions of youth who filled a psychotropic prescription overall and by psychotropic class, stratified by age and gender. Results: Of the 8,896,713 children and adolescents in the sample, 24.7% received psychotropic medication during the study period. The proportion of the cohort prescribed a psychotropic medication in a given month averaged 27%-28% from January 2019 to February 2020, peaked at 36.9% in April 2020, and gradually declined to 28.7% in September 2020. The largest year-over-year percent change was in April for antipsychotic (41.9%) and antidepressant (37.9%) medication, which remained higher in September 2020 compared to September 2019, particularly among ages 6 years or older and females. Conclusion: The proportion of youth with a psychotropic prescription increased at the onset of the COVID-19 pandemic, later returning to prepandemic levels. However, antipsychotics and antidepressants remained higher than prepandemic, highlighting the need to further understand the long-lasting effects of the pandemic on children and adolescents.

Hyperglycemia and Hypoglycemia Are Associated with In-Hospital Mortality among Patients with Coronavirus Disease 2019 Supported with Extracorporeal Membrane Oxygenation.

Metabolic abnormalities, such as preexisting diabetes or hyperglycemia or hypoglycemia during hospitalization aggravated the severity of COVID-19. We evaluated whether diabetes history, hyperglycemia before and during extracorporeal membrane oxygenation (ECMO) support, and hypoglycemia were risk factors for mortality in patients with COVID-19. This study included data on 195 patients with COVID-19, who were aged ≥19 years and were treated with ECMO. The proportion of patients with diabetes history among nonsurvivors was higher than that among survivors. Univariate Cox regression analysis showed that in-hospital mortality after ECMO support was associated with diabetes history, renal replacement therapy (RRT), and body mass index (BMI) < 18.5 kg/m2. Glucose at admission >200 mg/dL and glucose levels before ventilator >200 mg/dL were not associated with in-hospital mortality. However, glucose levels before ECMO >200 mg/dL and minimal glucose levels during hospitalization <70 mg/dL were associated with in-hospital mortality. Multivariable Cox regression analysis showed that glucose >200 mg/dL before ECMO and minimal glucose <70 mg/dL during hospitalization remained risk factors for in-hospital mortality after adjustment for age, BMI, and RRT. In conclusion, glucose >200 mg/dL before ECMO and minimal glucose level <70 mg/dL during hospitalization were risk factors for in-hospital mortality among COVID-19 patients who underwent ECMO.

Work stress and perceived organisational support on young Korean nurses' care for COVID-19 patients.

Background: Since the outbreak of COVID-19 worldwide, frontline nurses have faced tremendous stress. Younger nurses in their early-to-mid careers can be more exposed to burnout and work stress, and perceived organisational support can influence the quality of nursing care for vulnerable patients. Aim: To identify the impact of younger nurses' work stress and perceived organisational support on their willingness to care for COVID-19 patients. Methods: The cross-sectional secondary data analysis included 211 hospital nurses (<35 years) in South Korea with a mean age of 24.60 years (SD=1.90). Multiple logistic regression analysis was used to identify the factors influencing willingness to care. Findings: Supplying personal protective equipment, training in the use of personal protective equipment, lower work stress, and positive perceptions of organisational support significantly increased early-career nurses' willingness to care. For mid-career nurses, being male and higher work stress significantly increased their willingness to care. Discussion: Support, including COVID-19-related education or training, should be provided to reduce work stress arising from being exposed to infection or while providing care to critically ill patients, especially among early-career nurses. Support from nurse managers, senior staff, and colleagues could help younger nurses cope better with the challenges of COVID-19, thus increasing their willingness to care. Conclusion: Perceived organisational support may facilitate early-career nurses' organisational commitment. Healthy work environments can relieve early-to-mid-career nurses' work stress, thus facilitating patient-centred care.

Analyzing Topics and Sentiments from Twitter to Gain Insights to Refine Interventions for Family Caregivers of Persons with Alzheimer's Disease and Related Dementias (ADRD) During COVID-19 Pandemic.

We randomly extracted Tweets mentioning dementia/Alzheimer's caregiving-related terms (n= 58,094) from Aug 23, 2019, to Sep 14, 2020, via an API. We applied a clustering algorithm and natural language processing (NLP) to publicly available English Tweets to detect topics and sentiment. We compared emotional valence scores of Tweets from before (through the end of 2019) and after the beginning of the COVID-19 pandemic (2020-). Prevalence of topics related to caregiver emotional distress (e.g., depression, helplessness, stigma, loneliness, elder abuse) and caregiver coping (e.g., resilience, love, reading books) increased, and topics related to late-stage dementia caregiving (e.g., nursing home placement, hospice, palliative care) decreased during the pandemic. The mean emotional valence score significantly decreased from 1.18 (SD 1.57; range -7.1 to 7.9) to 0.86 (SD 1.57; range -5.5 to 6.85) after the advent of COVID-19 (difference -0.32 CI: -0.35, -0.29). The application of topic modeling and sentiment analysis to streaming social media provides a foundation for research insights regarding mental health needs for family caregivers of a person with ADRD during COVID-19 pandemic.

Mental health nurses' disaster nursing competencies: A cross-sectional study.

The unprecedented and prolonged coronavirus disease 2019 (COVID-19) pandemic has escalated the gravity of disasters in the field of mental health. Nurses are health care providers who play a pivotal role in all phases of disaster management and psychiatric nurses are required to be prepared and equipped with competencies to respond to such disasters. This cross-sectional study aimed to investigate the effects of mental health nurses' professional quality of life on disaster nursing competencies. This study adhered to the STROBE checklist for observational research. Data were collected from 196 mental health nurses working in various settings, including hospitals and communities in South Korea. Compassion satisfaction and compassion fatigue were measured using the Korean version of the Professional Quality of Life Scale. Disaster nursing competencies were measured using the Disaster Nursing Preparedness-Response Competencies Scale. Multiple regression analysis showed that compassion satisfaction (ß = 0.36, P < 0.001) was the most potent predictor of disaster nursing competencies of mental health nurses, followed by participation in disaster nursing (ß = 0.15, P = 0.023) and disaster nursing-related education (ß = 0.15, P = 0.026); these factors explained 30.1% of the variance. Education programmes ensuring that mental health nurses are adequately prepared for disaster management should include theoretical content as well as simulation training using virtual situations that resemble actual disasters. Further, supportive leadership and work environments that encourage cohesive teamwork are needed to increase compassion satisfaction of nurses.

Central blood pressure lowering effect of telmisartan-rosuvastatin single-pill combination in hypertensive patients combined with dyslipidemia: A pilot study.

This multicenter, phase 4, Prospective Randomized Open, Blinded End-point (PROBE) study aimed to evaluate safety and efficacy of telmisartan/rosuvastatin single-pill combination (SPC) therapy on lowering central blood pressure (BP) compared with telmisartan monotherapy in hypertensive patients with dyslipidemia in Korea. Study was terminated earlier than planned due to COVID-19 pandemic, thus should be considered as a pilot study. Among 125 patients who met the inclusion criteria of hypertension and dyslipidemia (defined as 10-year Atherosclerotic Cardiovascular Disease risk score over 5%), 80 patients went through 4-week single-group run-in period with telmisartan 40-80 mg, then randomized to telmisartan 80 mg + rosuvastatin (10 or 20 mg) SPC group or telmisartan 80 mg monotherapy group. The central/brachial BP, brachial-ankle pulse wave velocity (baPWV), and augmentation index (AIx) were assessed at baseline and 16 weeks later. Mean brachial SBP changed from 135.80 ± 14.22 mmHg to 130.69 ± 13.23 mmHg in telmisartan/rosuvastatin group and from 134.37 ± 12.50 mmHg to 133.75 ± 12.30 mmHg in telmisartan monotherapy group without significant difference (between-group difference p = .149). Mean central SBP were reduced significantly in the telmisartan/rosuvastatin group with change from 126.72 ± 14.44 mmHg to 121.56 ± 14.56 mmHg while telmisartan monotherapy group showed no significant change (between-group difference p = .028). BaPWV changed from 1672.57 ± 371.72 m/s to 1591.75 ± 272.16 m/s in telmisartan/rosuvastatin group and from 1542.85 ± 263.70 m/s to 1586.12 ± 297.45 m/s in telmisartan group with no significance (between-group difference p = .078). Change of AIx had no significant difference (between-group difference p = .314). Both groups showed excellent compliance rate of 96.9 ± 4.5% with no significant difference in adverse rate. Telmisartan/rosuvastatin SPC therapy was more effective in lowering central BP compared with the telmisartan monotherapy. The results of this study showed benefit of additive statin therapy in hypertensive patients combined with dyslipidemia.

Associations among Solo Dining, Self-Determined Solitude, and Depression in South Korean University Students: A Cross-Sectional Study.

Although solo dining motivated by self-determined solitude can be a positive and healthy experience for individuals, solo dining that is not motivated by self-determined solitude can trigger physical and mental health problems. This study examined the associations among solo dining, self-determined solitude, and depression in university students. Accordingly, an online survey was conducted on 372 university students. The results show that students who live alone, those in poor health, and those with more frequent solo dining experiences had higher depression scores than others. Whereas satisfaction with solo dining was high when voluntary solitude was high, female students displayed higher depression scores when they had low self-determined solitude or high non-self-determined solitude, and when they had a higher frequency of eating lunch alone, compared to their male counterparts. University undergraduates who live and dine alone, owing to non-self-determined solitude, are highly vulnerable to mental health problems, including depression. Hence, interventions that foster social connectedness and entail the identification of factors accounting for students' non-self-determined solitude should be developed.

Changes in Core Competencies among Korean University Students Due to Remote Learning during the COVID-19 Pandemic.

This study aimed to determine the academic performance and learning skills of students who studied through remote teaching methods during the coronavirus disease 2019 (COVID-19) pandemic. It was conducted in February 2021 with 398 university students in South Korea. Data were collected through online surveys. Generalized estimating equations (GEEs) with an autoregressive correlation structure were employed to distinguish differences in core competencies, academic performance, satisfaction, and usefulness of teaching methods before 2019 and after the COVID-19 pandemic. The findings revealed that the overall core competencies of participants were significantly lower in 2020 than before the COVID-19 pandemic. Furthermore, knowledge construction, responsibility practice, and socialization were significantly low during the COVID-19 pandemic, whereas information management and identity value did not show a significant difference. However, problem-solving was higher during the COVID-19 pandemic. Enhancing the core competencies of university students is integral in the new learning environment of the post-COVID-19 era. It is necessary to devise approaches that improve the effectiveness of remote teaching methods and simultaneously augment student satisfaction.

Beneficial Effect of Statins in COVID-19-Related Outcomes-Brief Report: A National Population-Based Cohort Study.

OBJECTIVE: Although statins are widely prescribed lipid-lowering drugs, there are concerns about the safety of their use in the context of coronavirus disease 2019 (COVID-19), since statins increase the expression of ACE2 (angiotensin-converting enzyme 2). This study aimed to disclose the association between statins and 60-day COVID-19 mortality. Approach and Results: All patients hospitalized with laboratory-confirmed COVID-19 were enrolled in this study from January 19 to April 16, 2020, in Korea. We evaluated the association between the use of statins and COVID-19-related mortality in the overall and the nested 1:2 propensity score-matched study. Furthermore, a comparison of the hazard ratio for death was performed between COVID-19 patients and a retrospective cohort of patients hospitalized with pneumonia between January and June 2019 in Korea. The median age of the 10 448 COVID-19 patients was 45 years. Statins were prescribed in 533 (5.1%) patients. After adjusting for age, sex, and comorbidities, Cox regression showed a significant decrease in hazard ratio associated with the use of statins (hazard ratio, 0.637 [95% CI, 0.425-0.953]; P=0.0283). Moreover, on comparing the hazard ratio between COVID-19 patients and the retrospective cohort of hospitalized pneumonia patients, the use of statins showed similar benefits. CONCLUSIONS: The use of statins correlates significantly with lower mortality in patients with COVID-19, consistent with the findings in patients with pneumonia.

Different therapeutic associations of renin-angiotensin system inhibitors with coronavirus disease 2019 compared with usual pneumonia.

BACKGROUND/AIMS: Although it is near concluded that renin-angiotensin system inhibitors do not have a harmful effect on coronavirus disease 2019 (COVID-19), there is no report about whether angiotensin receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs) offer any protective role. This study aimed to compare the association of ARBs and ACEIs with COVID-19-related mortality. METHODS: All patients with COVID-19 in Korea between January 19 and April 16, 2020 were enrolled. The association of ARBs and ACEIs with mortality within 60 days were evaluated. A comparison of hazard ratio (HR) was performed between COVID-19 patients and a retrospective cohort of pneumonia patients hospitalized in 2019 in Korea. RESULTS: Among 10,448 COVID-19 patients, ARBs and ACEIs were prescribed in 1,231 (11.7%) and 57 (0.6%) patients, respectively. After adjusting for age, sex, and history of comorbidities, the ARB group showed neutral association (HR, 1.034; 95% CI, 0.765 to 1.399; p = 0.8270) and the ACEI groups showed no significant associations likely owing to the small population size (HR, 0.736; 95% CI, 0.314 to 1.726; p = 0.4810). When comparing HR between COVID-19 patients and a retrospective cohort of patients hospitalized with pneumonia in 2019, the trend of ACEIs showed similar benefits, whereas the protective effect of ARBs observed in the retrospective cohort was absent in COVID-19 patients. Meta-analyses showed significant positive correlation with survival of ACEIs, whereas a neutral association between ARBs and mortality. CONCLUSION: Although ARBs or ACEIs were not associated with fatal outcomes, potential beneficial effects of ARBs observed in pneumonia were attenuated in COVID-19.

Extracorporeal Membrane Oxygenation for Coronavirus Disease 2019: Expert Recommendations from The Korean Society for Thoracic and Cardiovascular Surgery.

Since the first reported case of coronavirus disease 2019 (COVID-19) in December 2019, the numbers of confirmed cases and deaths have continued to increase exponentially despite multi-factorial efforts. Although various attempts have been made to improve the level of evidence for extracorporeal membrane oxygenation (ECMO) treatment over the past 10 years, most experts still hesitate to take an active position on whether to apply ECMO in COVID-19 patients. Several ECMO management guidelines have been published recently, but they reflect some important differences from the Korean medical system and aspects of real-world medical practice in Korea. We aimed to find evidence on the efficacy of ECMO for COVID-19 patients by reviewing the published literature and to propose expert recommendations by analyzing the Korean COVID-19 ECMO registry data.
