The Worldwide Prevalence of Sleep Problems Among Medical Students by Problem, Country, and COVID-19 Status: a Systematic Review, Meta-analysis, and Meta-regression of 109 Studies Involving 59427 Participants.

Purpose of Review: Several studies have found that medical students have a significant prevalence of sleep issues, such as poor sleep quality, excessive daytime sleepiness, and inadequate sleep duration. The purpose of this review is to carefully evaluate the current research on sleep problems among medical students and, as a result, estimate the prevalence of these disturbances. The EMBASE, PsychINFO, PubMed/MEDLINE, ScienceDirect, Scopus, and Web of Science and retrieved article reference lists were rigorously searched and rated for quality. Random effects meta-analysis was performed to compute estimates. Recent Findings: The current meta-analysis revealed an alarming estimated pooled prevalence of poor sleep quality (K = 95, N = 54894) of 55.64% [95%CI 51.45%; 59.74%]. A total of 33.32% [95%CI 26.52%; 40.91%] of the students (K = 28, N = 10122) experienced excessive sleepiness during the day. The average sleep duration for medical students (K = 35, N = 18052) is only 6.5 h per night [95%CI 6.24; 6.64], which suggests that at least 30% of them get less sleep than the recommended 7-9 h per night. Summary: Sleep issues are common among medical students, making them a genuine problem. Future research should focus on prevention and intervention initiatives aimed at these groups.

Insomnia during coronavirus disease 2019 pandemic in Korea: a National sleep survey.

Coronavirus disease 2019 (COVID-19) pandemic has caused widespread increase in stress and affected sleep quality and quantity, with up to 30% prevalence of sleep disorders being reported after the declaration of the pandemic. This study aimed to assess perceived changes due to the pandemic in the prevalence of insomnia and excessive daytime sleepiness (EDS) in Korea, and identify the associated factors. An online survey was conducted among 4000 participants (2035 men and 1965 women) aged 20-69 years enrolled using stratified multistage random sampling according to age, sex, and residential area, between January, 2021 and February, 2022. The questionnaire included various items, such as socio-demographics, Insomnia Severity Index, and Epworth Sleepiness Scale (ESS). Insomnia was defined as difficulty falling asleep and difficulty maintaining sleep more than twice a week. EDS was classified as an ESS score ≥ 11. Insomnia was reported by 32.9% (n = 1316) of the participants (37.3% among women and 28.6% among men). Multivariate logistic regression revealed that insomnia was associated with female sex [odds ratio (OR) = 1.526, 95% confidence interval (CI) = 1.297-1.796], night workers (OR 1.561, 95% CI 1.160-2.101), and being unmarried (OR 1.256, 95% CI 1.007-1.566). EDS was reported by 12.8% (n = 510) of the participants (14.7% among men and 10.7% among women). EDS was associated with male sex (OR 1.333, 95% CI 1.062-1.674), and being employed (OR 1.292, 95% CI 1.017-1.641). During the COVID-19 pandemic, the prevalence of insomnia increased in Korea, while there was no significant change in EDS compared with pre-pandemic evidence.

Associations between Sleep, Depression, and Cognitive Performance in Adolescence.

The relevance of cognitive performance during adolescence requires further studies that analyze potential associated factors. This study aimed to analyze inductive reasoning, reading comprehension, and mathematical thinking (problem-solving and number and calculation) in relation to sleep and depression in 244 students aged 12-17 years (47.6% boys and 52.4% girls). Daytime sleepiness, sleep quality, dysthymia, and euthymia (state and trait) were assessed by self-reported questionnaires. Moreover, correlations between these variables and cognitive performance, and differences depending on sociodemographic variables (sex, age, or academic year) were analyzed using non-parametric tests. Robust regression models were also conducted to evaluate the predictive role of significant variables on cognitive performance. The results showed significant bidirectional relationships between sleep- and depression-related variables, and between the latter ones and cognitive performance. Depression-trait was more related to cognitive performance than depression-state, and euthymia more than dysthymia, but neither daytime sleepiness nor sleep quality significantly correlated with it. As for sociodemographic variables, girls reported worse sleep and more depressive symptoms than boys did, and younger students reported better sleep but performed worse than the older ones. Although these findings should be further explored in forthcoming studies adding other promising variables, they highlight the importance of promoting euthymia to improve cognitive performance in adolescents.

Assessment of Sleep Quality among Medical Students During the Covid- 19 Pandemic

Objective: To assess the sleep quality among medical students, comparing their sleep cycles during physical and online studies along with other factors associated with sleep patterns. Study Design: Cross-sectional Questionnaire based survey Place and Duration of Study: Department of Community Medicine, HITEC Institute of Medical Sciences Taxila from 1st January 2020 to 31st March 2020 Methodology: One hundred and forty seven students were surveyed in a time period of 1 month. The questionnaire included PSQI Pittsburgh Sleep Quality Index and other clinically validated questions. Students with known sleeping disorders were excluded from this survey. Result(s): There were 81 (55.1%) females and 65 (44.2%) males with mean age 20+/-1.4 years. Out of these 94(63.9%) were classified as "Poor Sleepers" and only 53 (36.1%) were "Good Sleepers". Poor sleep quality was associated with female gender (p<0.05), day-scholar residence status (p<0.054), excessive time required to sleep (p<0.00), excessive screen time usage (p<0.007), increased hours of study (p<0.089), experiencing trouble while driving, eating and socializing (p<0.002), lack of enthusiasm (p<0.000), unsatisfactory daily activities (p<0.000) and poor daytime alertness levels (p<0.360). 104 (70.7%) were aware of the effects of melatonin on sleep, only 51 (34.7%) admitted to have used coffee to stay awake at night. 98 (66.7%) subjects were pre-exam workers, 95 (64.6%) admitted not being able to wake up easily in the morning. Conclusion(s): The students and hostelites that used less screen time slept better. Excessive daytime tiredness was also a result of poor sleeping habits. Students who studied for longer periods of time and had difficulty waking up in the morning slept poorly. Poor sleepers also find it difficult to interact and are often unambitious about performing their daily menial tasks, as well as displeased with their daily activities. As a matter of fact, we deduce that sleep quality has unanticipated consequences for medical students' social and mental health.Copyright © 2023 Lahore Medical And Dental College.

Impact of Taiwan's 2021 COVID-19 lockdown on the symptom severity and quality of life of patients with narcolepsy.

COVID-19 lockdowns can influence the sleep quality and daytime condition of patients with narcolepsy. Using data from our cohort study, we investigated changes in the quality of life and the symptom severity of patients with narcolepsy during Taiwan's 2021 lockdown and investigated differences by narcolepsy subtype, sex, and age. Patients with type 1 and type 2 narcolepsy (NT1 and NT2, respectively) aged 6-40 years were retrospectively recruited from our narcolepsy cohort study. These patients were regularly evaluated using the Short Form 36 Health Survey questionnaire (SF-36), the Epworth Sleepiness Scale (ESS), the visual analog scale (VAS) for hypersomnolence, the VAS for cataplexy and sleep diary. We compared the differences between the lockdown and the prelockdown periods by narcolepsy subtype, sex, and age. We used a paired t test analysis to compare differences in the SF-36, ESS, VAS scores and data of sleep diary between the prelockdown and lockdown periods (p1), and an independent t test analysis was used to compare the changes in different subgroups between the prelockdown and lockdown periods (p2). A total of 120 patients with narcolepsy were recruited (mean age 24.22 ± 6.87 years; 58% male); 80 of the patients had NT1 (mean age 25.25 ± 6.79 years; 60% male) and 40 had NT2 (mean age 22.16 ± 6.64, 53% male). During the lockdown period, the ESS score of total patients was decreased (p = 0.039) and body mass index was increased (p = 0.02). The NT1 group decreased significantly (p1 = 0.017), especially in men (p1 = 0.016) and adults (p1 = 0.04); scores for the VT domain of the SF-36 increased significantly in male and adult patients with NT2 (p1 = 0.048 and 0.012). Additionally, male patients with NT2 exhibited significantly decreased scores in the physical and emotional role functioning domains (p1 = 0.028, 0.024). The children and adolescents with NT1 had significantly decreased scores in the general health domain of the SF-36, but no significant change was noted in that of adults (p1 = 0.027, p2 = 0.012). We observed both negative and positive impacts of Taiwan's 2021 lockdown on patients with narcolepsy. A more flexible but structured daily routine with adequate sleep time should be considered for this population during lockdown and nonlockdown periods.

Sleep disturbances in children with cystic fibrosis and primary ciliary dyskinesia at the beginning and in the first year of COVID-19 pandemic

Introduction: During the COVID-19 pandemic, the lifestyle and sleep habits of children with chronic lung disease have changed. Aims and objectives: To evaluate the differences in sleep habits in the first year of the pandemic in children with cystic fibrosis (CF) and primary ciliary dyskinesia (PCD). Method(s): Primary caregivers of children with CF and PCD aged 3-16 years who were evaluated for sleep habits at the beginning of the pandemic were re-evaluated at the end of the first year of the pandemic. The Sleep Disturbance Scale for Children (SDSC) was used and questions were asked about sleep habits and weight changes during the first year of the pandemic. Result(s): Primary caregivers of 31 children with CF and 14 children with PCD were included in the study. The median age of the children were 10.0 (7.5-12.0) years, 42.2% of the children were female. The mean BMI of children with CF was 15.8+/-1.8, and 20.0+/-3.5 in children with PCD (p:0.001). The mean daily screen time was 2h (1-3) at the beginning and 5h (4-6) in the first year of the pandemic among children with CF, 2h (1-2.2) at the beginning and 5h (4.7-6) in the first year of the pandemic among children with PCD (p<0.001, p:0.001, respectively). There were no differences in terms of disorders of initiating and maintaining sleep, sleep breathing disorders, disorders of arousal, sleep-wake transition disorders, disorders of excessive somnolence, sleep hyperhidrosis scores between two groups during first year of pandemic. Conclusion(s): While daily screen time increased in children with CF and PCD, sleep disturbances and changes in daily habits continued in the first year of the pandemic.

Sleep symptoms are essential features of long-COVID - Comparing healthy controls with COVID-19 cases of different severity in the international COVID sleep study (ICOSS-II).

Many people report suffering from post-acute sequelae of COVID-19 or "long-COVID", but there are still open questions on what actually constitutes long-COVID and how prevalent it is. The current definition of post-acute sequelae of COVID-19 is based on voting using the Delphi-method by the WHO post-COVID-19 working group. It emphasizes long-lasting fatigue, shortness of breath and cognitive dysfunction as the core symptoms of post-acute sequelae of COVID-19. In this international survey study consisting of 13,628 subjects aged 18-99 years from 16 countries of Asia, Europe, North America and South America (May-Dec 2021), we show that post-acute sequelae of COVID-19 symptoms were more prevalent amongst the more severe COVID-19 cases, i.e. those requiring hospitalisation for COVID-19. We also found that long-lasting sleep symptoms are at the core of post-acute sequelae of COVID-19 and associate with the COVID-19 severity when COVID-19 cases are compared with COVID-negative cases. Specifically, fatigue (61.3%), insomnia symptoms (49.6%) and excessive daytime sleepiness (35.8%) were highly prevalent amongst respondents reporting long-lasting symptoms after hospitalisation for COVID-19. Understanding the importance of sleep-related symptoms in post-acute sequelae of COVID-19 has a clinical relevance when diagnosing and treating long-COVID.

Insomnia, Daytime Sleepiness, and Quality of Life among 20,139 College Students in 60 Countries around the World-A 2016-2021 Study.

Background: Sleep disorders are a widespread phenomenon, and the number of individuals suffering from them is increasing every year, especially among young adults. Currently, the literature lacks studies that cover both countries with different levels of development and a period before the announcement of the ongoing COVID-19 pandemic. Therefore, this study aims to globally assess the prevalence of insomnia and daytime sleepiness among students and assess their quality of life. Methods: For this purpose, our own questionnaire was distributed online via Facebook.com. In addition to the questions that assessed socioeconomic status, the survey included psychometric tools, such as the Athens insomnia scale (AIS), the Epworth sleepiness scale (ESS), and the Manchester short assessment of the quality of life (MANSA). The survey distribution period covered 31 January 2016 to 30 April 2021. Results: The survey involved 20,139 students from 60 countries around the world. The vast majority of the students were women (78.2%) and also those residing in countries with very high levels of development and/or high GDP (gross domestic product) per capita at 90.4% and 87.9%, respectively. More than half (50.6%) of the respondents (10,187) took the survey before the COVID-19 pandemic was announced. In the group analyzed, 11,597 (57.6%) students obtained a score indicative of insomnia and 5442 (27.0%) a score indicative of daytime sleepiness. Women, low-income residents, and nonmedical students were significantly more likely to have scores indicating the presence of insomnia. Individuals experiencing both sleepiness (B = −3.142; p < 0.001) and daytime sleepiness (B = −1.331; p < 0.001) rated their quality of life significantly lower. Conclusions: Insomnia and excessive daytime sleepiness are common conditions among students worldwide and are closely related. The COVID-19 pandemic significantly altered students' diurnal rhythms, which contributed to an increase in insomnia. Students in countries with a high GDP per capita index are significantly less likely to develop insomnia compared to the residents of countries with a low GDP per capita index. Sleep disorders definitely reduce the quality of life of students.

Anxiety, depression, and sleep disorders among healthcare workers during the COVID-19 pandemic.

OBJECTIVE: In this study, we examined the level of anxiety and depression, daytime sleepiness, and sleep quality in healthcare workers working during the COVID-19 pandemic. METHODS: This study was conducted in a tertiary care university hospital. Socio-demographic information form, Beck Anxiety Scale, Beck Depression Scale, Pittsburg Sleep Quality Index, and Epworth Sleepiness Scale were used as data collection tools. RESULTS: A total of 273 healthcare workers were recruited into the study. It was determined that there is an enormous mental health burden on healthcare workers. About 100% and 45.4% of the participants got above-threshold scores from Beck Anxiety Scale, and Beck Depression Scale, and the prevalence of daytime sleepiness and impaired sleep quality was 11.4% and 38.8%, respectively. The female gender was found to have more severe anxiety levels and lower sleep quality (p<0.001). In logistic regression analysis, the female gender was a risk factor for having a level of severe anxiety, and the nursing profession was a risk factor for having severe anxiety and low sleep quality (p<0.05). CONCLUSION: Global serious outbreaks cause increased depression and anxiety levels and sleep disorders in healthcare workers. Therefore, we believe that trainings and support which aims to strengthen the psychological well-being of healthcare workers should be implemented.

A PATIENT WITH COVID-19 PNEUMONIA, PULMONARY EMBOLISM, AND OSA

SESSION TITLE: Global Case Reports in Critical Care SESSION TYPE: Global Case Reports PRESENTED ON: 10/19/2022 12:45 pm - 01:45 pm INTRODUCTION: Thrombotic complications in patients diagnosed with COVID-19 pneumonia are emerging as an important and significant morbidity and mortality burden, with overwhelming inflammation, hypoxia, immobilization, and diffuse intravascular coagulation among possible causes of a procoagulant state (1). Obstructive sleep apnea (OSA), with intermittent arterial oxygen desaturation, may in its turn contribute to a procoagulant state, causing hemodynamic alterations as polycythemia and sluggish blood flow (2). Here we report on a case of sudden and massive non-lethal pulmonary thromboembolism (PTE) in a patient with COVID-19 severe pneumonia, for whom OSA was suspected and documented as a possible concurrent mechanism of thromboembolic complication during follow-up. CASE PRESENTATION: A 55-year-old male non-smoker obese (BMI 33 Kg/m2) was admitted to our hospital after 9 days of fever. In the Emergency Room, a chest HRCT scan showed bilateral diffuse ground glass opacities. He was treated with subcutaneous Tocilizumab (324 mg) single shot, Remdesivir (200 mg/day for first day and 100/daily for further 4 days), methyl-prednisolone 40 mg/daily, Enoxaparin 6000 UI/twice daily, azithromycin 500 mg/daily, high flow nasal cannula oxygen (50 L/min, TC 34°C, FiO2 35%) for moderate acute respiratory failure due to COVID-19 pneumonia (pO2: 58 mmHg, PCO2 34 mmHg pH 7.50, P/F 275). After 10 days, patient's clinical conditions worsened, needing non-invasive respiratory support;D-dimer increased abruptly, rising to 10 ng/mL, with findings consistent with PTE at a computed tomographic angiography (CTA, Fig 1). The patient was successfully treated with 10 mg/daily subcutaneous fondaparinux for 12 days, while assisted in the Intensive Care Unit, being discharged home in room air shortly later with oral anticoagulants. At the 3-month follow-up visit, OSA was suspected due to reported excessive daytime sleepiness and weakness, snoring, disturbed night sleep, morning headache in the last 4 years. The patient underwent a home sleep apnea test (HSAT) overnight. Test results revealed an AHI of 50 events/h, with several prolonged episodes of obstructive sleep apnea (307 apnea and hypopnea (A+H) events, 70 obstructive apnea and 233 hypopnea events, with a mean duration of 10% and an average arterial saturation of 93% (Fig. 2). He was adapted to CPAP therapy, with benefit and good correction of polygraphic indexes. DISCUSSION: The pathogenetic mechanisms of COVID 19 and OSA could have played a synergistic effect on endothelial damage, thus increasing the risk of thromboembolism. CONCLUSIONS: The presence of underdiagnosed comorbidities may well worsen the clinical course and complication of COVID-19;an earlier diagnosis of OSA is a prerequisite for timely treatment and, potentially, improved long-term clinical outcomes.

Retrospective analysis of individualised melatonin regimens and a multidisciplinary targeted approach in managing insomnia during the second wave of COVID-19

Introduction: The therapeutic benefits of sleep in the critically ill has been extensively studied in the medical literature.1 Chronic insomnia increases a patient's risk of delirium, cortical atrophy, diabetes, cancer, cardiovascular death from arterial hypertension, myocardial infarction and heart failure.2 Insomnia reduces interaction during videocalls with family and limits co-operation with physiotherapy, medical and nursing interventions, potentially delaying rehabilitation and recovery. Objectives: To improve sleep by introducing an individualised melatonin regimen and a multidisciplinary targeted approach to managing insomnia in an adult intensive care unit. Methods: A retrospective analysis was conducted in a single centre UK adult ICU. Data was retrieved from pharmacy dispensing records, electronic medical notes and prescriptions from September 2020 to March 2021. The primary outcome was resolution of insomnia. Other information collected included causes of insomnia, referral to psychology for cognitive behavioural therapy (CBT), prevalence and resolution of delirium, adverse effects, and death. Each patient received a tailor made regimen based on Bellapart et al's original concept of mimicking the natural endogenous secretion of melatonin.3 However, unlike previous studies3,4,5 dosing was modified and adjusted according to patient response. A loading dose of 0.75 to 3mg was administered at 21:00 followed by a smaller hourly dose of 0.25 to 0.5mg between 22:00 and 03:00. Additionally, the duration of treatment continued for as long as therapeutic benefit was realised, which included post discharge from ICU. Prior experience of conventional melatonin dosing did not demonstrate therapeutic benefit from the original pilot study and when nursing staff inadvertently omitted the hourly dose between 10pm and 3am. Adverse effects were documented. Sleep hygiene measures were introduced and standardised where possible e.g. ear plugs, eye mask, dim lights, environmental noise reduction and minimal night time physical interventions from nursing and medical staff. The principal investigator referred to psychology patients who expressed fear and anxiety as a cause of insomnia. Results: 132 patients were admitted during September 2020 to March 2021. 30 patients received tailor made melatonin regimens (22.7%). The medical notes of four (13.3%) patients could not be accessed for data collection and were, therefore, excluded from the study. The primary outcome of resolution of insomnia occurred in 23 out of 26 (88.4%) patients. At the time of ICU discharge, delirium had occurred in 15 patients (57.7%), resolved in 10 patients (66.7%), three (20%) patients remained intermittently delirious, one remained continuously delirious, and one died. Mechanical ventilation, environmental noise, necessary medical and nursing interventions throughout the night and infection accounted for 23 (88.4%) of patients' insomnia. Fear or anxiety were expressed by eight (30.8%) patients as a cause of insomnia whilst medicines e.g. steroids, beta blockers accounted for six patients (26.1%). Seven patients (26.9%) expressing fear or anxiety were referred to psychology for adjunctive CBT. One patient experienced excessive daytime drowsiness, which resolved with dose regimen adjustment. One patient died of a cause unrelated to melatonin. Conclusion: An individualised melatonin regimen combined with a multidisciplinary targeted approach can result in resolution of insomnia in ICU patients, with minimal risk of adverse effects.

Dark nighttime interventions and sleep quality in intensive care unit patients: A systematic review and meta‐analysis

Background Aim Study Design Results Conclusion Relevance to Clinical Practice Sleep disturbances resulting from adverse clinical and environmental conditions are associated with unfavourable outcomes in critically ill patients.To collect evidence on the effect of dark nighttime interventions on sleep quality and daytime sleepiness in intensive care unit (ICU) patients.The study followed the Preferred Reporting Items for Systematic reviews and Meta‐Analyses recommendations. This is a systematic review and meta‐analysis of experimental and quasi‐experimental studies, developed with adult patients admitted to ICUs and submitted to measures such as environmental brightness reduction, eye mask or blue light‐blocking glass use at night. Outcomes were subjective or objective sleep quality and excessive daytime sleepiness. Search was carried out in the PubMed/MEDLINE, Cochrane Library, Embase, Virtual Health Library, Cumulative Index to Nursing and Allied Health Literature, Web of Science, and Scopus databases, using grey literature. Covidence software, Cochrane tools and Grading of Recommendations Assessment, Development and Evaluation were used, and a meta‐analysis was performed using RevMan software.Thirteen articles were included in the systematic review and seven studies were included in the meta‐analysis. There were 3 trials with 175 participants regarding lighting reduction and environmental noise control versus the usual routine, 2 of these trials, with 96 patients, were compiled in meta‐analysis in which it was observed a significant statistical improvement in subjective sleep quality, mean difference (MD) of 11.89 points (0–100);95% confidence interval (CI) 8.0–15.76, evidence set with moderate certainty, as well as this same intervention, reduced daytime sleepiness in 2 trials, 135 participants (standardized MD −0.63;95% CI −0.98 to −0.28), with low certainty evidence. Eye masks versus usual routine, 2 trials, 126 participants, improved subjective sleep quality (MD of 10 points;95% CI 7.97–12.03), with moderate certainty of evidence. Eye mask use combined with other therapies versus usual routine, 5 trials, 204 participants, improved subjective sleep quality in all studies, with low certainty of evidence. Objective sleep assessment was not improved with these interventions.This review shows some benefits of nighttime interventions on subjective sleep quality and excessive sleepiness, however, there is an urgent need to conduct better and more robust studies in this field.applying measures such as lighting reduction and eye mask use significantly improves sleep quality.

Adolescent mobile phone addiction during the COVID-19 pandemic predicts subsequent suicide risk: a two-wave longitudinal study.

Both the rate of mobile phone addiction and suicidality among adolescents have increased during the pandemic lockdown. However, the relationship between mobile phone addiction and suicide risk and the underlying psychological mechanisms remains unknown. This study examined the associations between mobile phone addiction in adolescents during the first month of lockdown and the suicide risk in the subsequent five months. A two-wave short-term longitudinal web-based survey was conducted on 1609 senior high school students (mean age = 16.53 years, SD = 0.97 years; 63.5% female). At Time 1 (T1), the severity of mobile phone addiction and basic demographic information was collected from Feb 24 to 28, 2020 in Sichuan Province, China (at the pandemic's peak). Five months later, between July 11 and July 23 (Time 2, T2), mobile phone addiction, daytime sleepiness, depression, and suicidality were measured within the past five months. The regression analysis revealed that mobile phone addiction during quarantine directly predicted suicidality within the next five months, even after controlling for the effect of depression and daytime sleepiness. Meanwhile, mobile phone addiction at T1 also indirectly predicted suicidality at T2, with depression and daytime sleepiness mediating this association. Programs targeting improvement of daytime sleepiness and depressive symptoms may be particularly effective in reducing suicide risk among adolescents with mobile phone addiction.

Sleep disturbances in craniopharyngioma: a challenging diagnosis

Introduction: The hypothalamus plays a crucial role in regulating vital functions and circadian rhythms. Both the tumor involving the hypothalamic area and its treatment can lead to hypothalamic dysfunction, resulting in disturbances in sleep-wake patterns, sleep fragmentation, and increased daytime sleepiness. We describe two patients with craniopharyngioma who came to our attention due to the occurrence of episodes characterized by psychomotor slowing and afinalistic limb movements, temporal and spatial disorientation, psychomotor agitation, and oneiric stupor like episodes diagnosed as severe sleep disturbances. Case reports: Patient 1 is a 19-year-old male diagnosed with surgically treated craniopharyngioma. Subsequently, episodes of psychomotor slowing, afinalistic movements of the upper limbs diagnosed as seizures in another neurological center appeared;antiepileptic treatment was started without improvement. At the first examination in our center, excessive daytime sleepiness (EDS), fragmented nighttime sleep, episodes characterized by bimanual automatic gestures occurring during drowsy state, hypnagogic hallucinations, and sudden loss of muscle tone while awake were recognized. Actigraphy demonstrated irregular bedtimes, frequent nocturnal activity, and inappropriate daytime rest episodes. The Epworth Sleepiness Scale (ESS) showed subjective EDS (ESS=19). At PSG, hypersomnolence, severe sleep-related breathing disorder (SRBD), and no interictal and ictal seizure abnormalities were found. A BiPAP NIV was started, and antiepileptic therapy was discontinued. In the following months, PSG revealed marked improvement in SRBD and 1 SOREMP, and the MSLT a mean SOL of 6 min and 10 sec and 3 SOREMPs. These data allowed the diagnosis of secondary narcolepsy, and treatment with pitolisant was initiated with clinical improvement and reduced daytime sleepiness (ESS=9). Patient 2 is a 12-year-old male, surgically treated for craniopharyngioma at the age of 4 years, who developed episodes of myoclonic jerks, temporal and spatial disorientation, and psychomotor agitation during the lockdown period for COVID-19 emergency. Surmising paroxysmal epileptic episodes, the patient was hospitalized. The anamnestic data collection revealed a sleep-wake rhythm dysregulation, fragmented nighttime sleep, EDS, oneiric stupor-like episodes during which the patient performed simple automatic gestures mimicking daily-life activity, and severe impairment of alertness. The Long-term video-EEG, including polygraphic measurements, showed destruction of the wake-NREM sleep-REM sleep boundaries, episodes of undetermined state of vigilance, and concurrence of elements typical of different sleep stages. Moreover, a severe SRBD (AHI 19/h) has been observed. The MRI showed a volumetric increase in the post-surgical interpeduncular fossa and right paramedian cysts. Therefore, a multifactorial therapeutic plan including sleep hygiene and slow-release melatonin was started with improvement in nighttime sleep, but EDS persisted. Surgical treatment of cyst fenestration improved sleep-wake rhythm and behavior;BiPAP NIV was initiated with very poor adherence. Discussion: We aim to focus on sleep disorders as a possible complication of tumors involving the hypothalamic region. Our cases highlight that the clinical manifestation of these dysfunctions can be challenging to diagnose and can lead to misdiagnosis and inappropriate treatment that can harm patients' health and the quality of life of patients and their families. Conclusion: These findings support the need to incorporate comprehensive sleep assessment in survivors from childhood brain tumors involving the suprasellar/hypothalamic region.

Wake Up and Learn - A School Based Sleep Education and Surveillance Program: Excessive Daytime Sleepiness a Common Concern

Introduction: "Wake Up and Learn" (WUAL) is a population based preventative sleep screening and education program for 7th to 12th graders through an asynchronously delivered virtual platform. The program was intentionally developed to be completely virtually delivered for scalability, which was of advantage during COVID allowing for the program to continue to be implemented with modest delays related to school schedule changes. This is a descriptive summary of excessive daytime sleepiness over two time points during the academic school year. Materials and Methods: The 7th to 12th grade students of Montgomery school district (Pennsylvania) were given an opt-out option for participation in the WUAL program. The surveys were generated using REDcap and included the Epworth sleepiness scale-CHAD (ESS-CHAD) and the childhood sleep habits questionnaire (CHSQ). The surveys became available online via the WUAL website (wakeupandlearn.org) and the students were instructed to access the website and complete the surveys as part of class time. Surveys were completed in December 2020 for the first time and then again in April 2021 as part of the planned three times per year surveillance. Due to school schedule changes experienced related to COVID the first survey planned for beginning of the academic year was skipped. Results: A total of 344 students completed ESS-CHAD in December 2020. There were 57 students with ESS scores greater than 10 (16.5%). In April, a total of 321 students completed ESS-CHAD with 49 students (15%) having ESS scores greater than 10. Of those with abnormal scores in December 15 (26%) had persistent sleepiness, 28 (49%) improved, and 14 (25%) did not provide a completed survey in April 2021. With this said, 34 (69%) of the respondents in April 2021 were newly identified to have pathologic sleepiness. 31% with persistent EDS from December 2020. Conclusions: Excessive daytime sleepiness is common in this adolescent high school cohort, but may not remain persistent over time. The majority of students who provided follow up responses had resolution of complaints of excessive daytime sleepiness between the two time points. Alarmingly, however, 34 additional students endorsed new complaints of EDS. Further examination of trends of EDS over time in this age group is required to better determine if this pattern is replicated in different school districts. If this is replicated it will be important to further explore factors that contribute to development, persistence and recovery from EDS. It is important to note that COVID and varying school structures (i.e in-person, virtual, hybrid) may have played a role in these findings. Wake Up and Learn is an on going program with plans for further expansion into additional school districts that may provide further insights into these trends.

Prevalence of sleep disorders symptoms in health professionals attending patients with suspicion or confirmation of COVID-19

Introduction: In November 2019, in China, an outbreak of a disease caused by the new coronavirus (SARS-CoV-2) has begun. The spread of Coronavirus Disease 2019 (COVID-19) to hundreds of countries, causing respiratory illness and death, especially in risk groups, led the World Health Organization to declare a pandemic in March 2020. For patient's management, an extensive network of multidisciplinary care is necessary, exposing them to a greater contamination risk. Objective: This study aims to describe the prevalence of sleep disorders on health professionals who care for patients with suspicion/ confirmation of COVID-19. Methods: This is a crosssectional study, carried out using an online form sent to health professionals, with higher education, of both genders, aged 18 years or more, from any city in Brazil. Data collection took place from August to December 2020 (epidemiological weeks 32 to 53). The participants were asked about the frequency of several sleep disorders, sociodemographic, health and lifestyle characteristics. Subsequently, descriptive statistics were performed. The study protocol was approved by the National Research Ethics Committee (CONEP) under opinion 4.073.427. Results: The sample consisted of 184 health professionals with an average age of 37 (±9,3) years, predominantly female (69,9%), physicians (48,4%), living in Rio Grande do Sul (77,7%), graduated in the last 10 years (53,3%), working in the morning (83,1%), afternoon (82,6%) and night (32,1%), who have non-transferable chronic diseases (25,5%), consume alcoholic beverages (54,9%) and practice physical activities (57,6%). Regarding sleep disorders, participants presented tiredness on waking up (88,6%), waking up at night (82,1%), excessive daytime sleepiness (73,4%), nightmares (69,6%), difficulty in starting sleep (69%), waking up too early and not being able to go back to sleep (63,6%), grinding or clenching teeth during sleep (59,2%), snoring (58,7%), sleep apnea (13%) and sleepwalking (8,7%). 74,5% of participants had 5 or more symptoms simultaneously. Conclusion: The results demonstrate a high number of symptoms of sleep disorders in the sample, especially tiredness on waking up and night awaking, as well as a high number of health professionals with 5 or more associated symptoms. The data are of concern, as they affect the performance of these professionals, which may expose them and the patients to greater risks.

Sleep quality in patients in the rehabilitation phase after COVID-19 diagnosis

Introduction: The inflammatory process and multisystemic manifestation caused by Covid-19 infection can involve multiple sequelae with damage on physical, cognitive, psychological, and biological aspects. This condition results on poor quality of life, fatigue, dyspnea and sleep difficulties. The focus on sleep difficulties, the most common symptoms are related to night drowsiness and insomnia, but little is known about the clinical characteristics of these patients who develop this complication. Objective: Evaluate the main complaints and clinical signs in patients after COVID-19. - Rate the quality of sleep in post-COVID-19 Syndrome patients who have had mild, moderate and/or severe symptoms of the disease. Methods: Observational study and descriptive, with a quantitative approach to data. A general and a specific sleep quality questionnaire were applied to patients undergoing rehabilitation after the diagnosis of COVID-19, who did or did not need to be hospitalized, with symptoms that had started at least 5 weeks before the questionnaire response date. Participants who were unable to answer the questionnaires due to a deficit in understanding the questions asked, or who gave up on completing the questionnaires without finishing, were excluded. Results: 177 participants participated in the research, 124 men (70%) and 53 women (30%). 62.7% of participants reported at least one comorbidity and only 23 people (12.9%) were not vaccinated with any dose until participation in this study. With regard to hospital admission, 109 participants (61.6%) required admission to the ICU and of these, 57.8% (63) required orotracheal intubation, with prolonged hospital stay for more than 12 days. The most common symptoms after covid-19 were muscle fatigue (78.3%), excessive daytime sleepiness (51.4%), persistent cough (47.4%) and headache (47.1%). 81.4% of participants reported that they felt their sleep quality had worsened after the diagnosis of COVID-19. And after applying a specific questionnaire (PSQI), 93.7% of participants were classified as poor sleepers. There was a very strong correlation (r>0.9) with participants who assessed hospitalized and in invasive mechanical ventilation, with bad sleep quality. Conclusion: The post-COVID-19 Syndrome, associated with age, comorbidities, length of stay and use of invasive mechanical ventilation, were factors that are associated with a higher prevalence of sleep disorders.

Online workshop proposal on sleep hygiene during the COVID-19 pandemic

Introduction: Inadequate sleep habits can compromise the quality of sleep and performance in activities of daily living of the individual, even more, considering the COVID-19 pandemic, which significantly interfered in the sleep and mental health of the population. Objective: To encourage the perception of habits that negatively influence the sleep quality of young people during social isolation in times of COVID-19. Methods: A workshop was proposed through the Youtube platform, during a scientific event on “Mental Health”. Two speech therapists organized a workshop with the theme “Sleep care practices”. The theme was divided into three parts. First, the basic concepts in sleep, the notion of sleep phase distribution, and consequences of sleep deprivation were addressed. The second part included the explanation and stimulation for self-application of the Mini Sleep Questionnaire (MSQ) from the Epworth Sleepiness Scale (ESS). This MSQ questionnaire was selected because, in addition to being self-administered, it assesses the frequency of sleep-related complaints and the ESS Scale subjectively assesses excessive daytime sleepiness. Finally, the third and last part consisted of reflections on sleep hygiene, with tips on how to improve these behaviors and habits. Results: The interactive proposal based on practice in brainstorming, aimed to generate reflections to participants, seeking to highlight inappropriate points in their routines, in order to enable a new planning of behaviors related to habits that influence the various aspects of sleep hygiene. In eight days of making the video available on the aforementioned platform, 3,624 views and 388 likes were achieved. The total video time was 22 minutes and 20 seconds, with the first part having 5 minutes and 21 seconds, the second part with 6 minutes and 6 seconds and the third with 11 minutes. Conclusion: Through information and communication technologies it was possible to encourage and raise awareness of a considerable population with regard to practices favorable to quality sleep, in a short period of time.
