    Abstract: Background: Because Korea is the fastest aging country, the stroke incidence is increasing rapidly. We investigate the trend of the number of patients with acute stroke in recent years and estimate the burden of the neurologist to treat the acute stroke patient visited the emergency department.Methods: We requested a questionnaire survey to all teaching hospitals on the number of hospital beds, the number of stroke patients who visited the emergency department, the number of stroke patients in charge of the neurologist, and the number of days on duty of residents from 2016 to 2019.Results: Of 69 teaching hospitals, 41 hospitals answered the survey. The average hospital beds per hospital were increased annually from 909 to 916. The average patients who visited the emergency department with stroke and were in charged to neurologists were rapidly increased from 799 to 867 per hospital. In particular, the number of patients with hyperacute cerebral infarction requiring the thrombolytic administration or mechanical thrombectomy were rapidly increased from 105 to 131. On the other hand, the average number of residents per hospital was decreased from 5.1 to 4.8. Therefore, the days on duty per resident were increased from 74 to 77.Conclusions: The number of acute stroke patients, especially, hyperacute stroke required the rapid cooperation and high labor were increasing rapidly in recent years. However, because the number of residents were decreased, the burden was increasing. To improve the quality of acute stroke treatment, it is necessary to increase the number of residents.

    Abstract: Background: To evaluate workload in emergency rooms (ERs) among clinical specialties including neurology and investigate characteristics of neurological consultations in ER.Methods: A nationwide survey was conducted to evaluate the number of specialists, resident physicians/surgeons, and emergency consultations of each clinical specialty in Korean tertiary referral hospitals from 2018 to 2019. Characteristics of neurological emergency consultations during the same period were investigated in one of the hospitals that participated.Results: A total of 23 hospitals were included. Four irrelevant clinical specialties were excluded. The number of neurology specialists and resident physicians were 12.5/hospital (4.1% of all specialists) and 6.4/hospital (3.4% of all resident physicians/surgeons), respectively, while the mean numbers of specialists and resident physicians or surgeons per clinical specialty were 13.7/hospital and 8.6/hospital, respectively. Neurological consultations accounted for 11.0% of all ER consultations for severe patients (Korean Triage and Acuity Scale level 1-3). Annual ER consultations for severe patients per neurology specialist was 274.1, which was only second to pediatrics (290.0). Annual ER consultations for severe patients per resident physician was 406.6 which was 1.6 times higher than the second highest (internal medicine, 247.0). Frequent conditions for neurological ER consultation were dizziness (24.8%), motor weakness (23.9%), headache (10.6%), dysarthria (9.9%), and seizures (7.7%). Frequent primary diagnoses were cerebrovascular diseases (29.0%) and episodic and paroxysmal disorders (24.9%).Conclusions: Workloads of neurology specialists for ER consultation were significantly heavy, and the workload of neurology resident physicians was the heaviest among all specialties. This should be considered in health care policies.

    Abstract: The present study aimed to examine the association between morningness‐eveningness preferences, sleep duration, weekend catch‐up sleep duration and depression among Korean high‐school students. A total of 8,655 high‐school students participated from 15 districts in South Korea and completed an online self‐report questionnaire. The following sleep characteristics were assessed: weekday and weekend sleep duration, weekend catch‐up sleep duration, morningness‐eveningness preference, perceived sufficiency of sleep, self‐reported snoring and sleep apnea, daytime sleepiness, and sleep environment. Age, gender, body mass index, number of private classes, proneness to internet addiction, and depressive mood were also evaluated. A logistic regression analysis was conducted to compute odds ratios for the association between depression and sleep characteristics, after controlling for relevant covariates. Eveningness preference was a significant predictor of depressive mood (adjusted OR, 1.71; 95% CI, 1.47–1.99). Weekend CUS durations that were ≥2 hr and enrollment in numerous private classes were associated with a lower risk for depression (0.68, 0.55–0.85; 0.76, 0.60–0.95; respectively). Female gender, underweight and obese body weight, short weekday sleep durations, excessive daytime sleepiness, perceived excessiveness and insufficiency of sleep, self‐reported snoring and sleep apnea, proneness to internet addiction and a non‐optimal sleep environment were associated with an increased risk for depression. Eveningness preference and insufficient weekday sleep duration were associated with an increased risk for depression. Weekend CUS duration ≥2 hr reduced the risk for depression. Diverse aspects, including sleeping habits and sleep‐related environmental factors, should be considered to reduce depressive symptoms in late adolescents.

    Abstract: This study was conducted to investigate sex differences in the prevalence and clinical presentation of migraine and probable migraine in a general population‐based sample. Background While there is research on sex differences in clinical characteristics and their impact on migraine headache, only few studies have investigated sex differences in probable migraine in population‐based settings. Moreover, compared with Western countries, the prevalence of probable migraine in Asia is relatively high. This cross‐sectional study was designed to investigate sex differences in the prevalence and clinical presentation of migraine and probable migraine in a general population‐based sample. Methods We used the data of the Korean Headache‐Sleep Study, which is a nationwide survey on headache and sleep. Results We interviewed 7430 people, and 3114 of them agreed to participate in our study (rejection rate, 58.1%). Among these people, 419 withdrew their participation during the interview. Ultimately, 2695 people completed our survey (cooperation rate, 36.3%). The prevalence of overall migraine and probable migraine was 350/1350 (25.9%) for women and 172/1345 (12.8%) for men ( P   〈  .001, respectively). The prevalence of migraine (107/1350 [7.9%] vs 36/1345 [2.7%] , P   〈  .001) and probable migraine (243/1350 [18.0%] vs 136/1345 [10.1%] , P   〈  .001) was significantly higher among women than among men. Headache frequency per month (median [interquartile range]) (1.0 [0.3–3.0] vs 0.8 [0.3–2.0], P  = .037), the visual analog scale score for headache intensity (5.0 [4.0–7.0] vs 5.0 [3.0–6.0] , P  = .019), and the impact of headache {Headache Impact Test‐6 score (47.0 [42.0–54.0] vs 44.0 [42.0–51.8] , P  = .013)} were significantly higher among women with probable migraine than men. Headache frequency per month (2.0 [0.4–4.0] vs 1.0 [0.3–2.0] , P  = .073), headache intensity (6.0 [5.0–8.0] vs 6.0 [4.2–7.0] , P  = .281), and the impact of headache (55.0 [48.0–61.0] vs 49.0 [46.3–60.8] , P  = .225) were not significantly different between women and men with migraine. Other comorbidities or associated symptoms, such as anxiety and depression, were not significantly different between women and men with migraine and probable migraine, except for nausea in probable migraine. Conclusion Women experience more severe symptoms and a higher impact of headache than men among participants with probable migraine. Our findings suggest that women with PM need a more intensive evaluation and treatment than men with PM.

    Abstract: Studies focusing on the association between sleep habit and parasomnia in adolescents are relatively scarce compared to other age group. Our study aimed to investigate the association between sleep duration and abnormal behavior during sleep (ABS) in Korean adolescents. Methods In this cross-sectional study, we evaluated 25,789 adolescents between 12 and 18 years of age (mean 15.76 ± 1.73 years; male 48.51%). Global Sleep Assessment Questionnaire and self-report questionnaires were used to assess ABS, sleep habits including catch-up weekend (CUW) sleep duration, and various socio-behavioral factors as covariates. Results The prevalence of ABS was 3.39% (n = 873). The analyses of multivariate logistic regression of the adjusted OR for ABS were significantly associated with male (OR, 1.304; 95% CI, 1.111 - 1.532), usually/always snoring (OR, 3.452; 95% CI, 2.800 - 4.257), usually/always witnessed sleep apnea (OR, 5.494; 95% CI, 4.143 - 7.286), weekday sleep duration (OR, 0.850; 95% CI, 0.797 - 0.90), weekend sleep duration (OR, 1.041; 95% CI, 1.004 - 1.080), CUW sleep duration (OR, 1.063; 95% CI, 1.026 - 1.101), perceived insufficient sleep (OR, 1.299; 95% CI, 1.092 - 1.545), increased internet addiction (OR, 1.031; 95% CI, 1.024 - 1.038), often coffee consumption (OR, 1.857; 95% CI, 1.443 - 2.390), often alcohol consumption (OR, 2.377; 95% CI, 1.292 - 4.374), sleeping with a doll or pets (OR, 1.60; 95% CI, 1.351 - 1.895), and keeping TV or radio during sleep (OR, 1.325; 95% CI, 1.084 - 1.619). Conclusion Short weekday sleep duration and CUW sleep duration are associated with abnormal behavior during sleep in Korean adolescents. Support (if any)

    Abstract: Sleep patterns have been linked to various heath disease. Evaluating population-level trend of sleep could provide a comprehensive population health-forecasting model that has the potential to inform targeted interventions. Therefore, we aimed to examine the cross-sectional differences in sleep characteristics among Korean adults during a 9-year period of 2009-2018. Methods The data in this study were derived from two nationwide survey regarding sleep and headache in the representative sample of Korean adult population, namely the Korean Sleep Headache Study phase I (2009) and II (2018). The survey was conducted through door-to-door visit and face-to-face interview by using structured questionnaires. Total of 2,836 participants from Phase I (47.9±16.4 years old; female, 50.2%) and 2,501 participants (47.9±16.4 years old; female, 50.3%) from Phase II gave informed consents and completed the survey. For this study, we excluded those who worked as shift workers and missing data. From the MCTQ, we collected participants’ sleep schedule during workdays and free days over the past four weeks. Average sleep duration was a weighted mean of sleep duration on workdays and free days. Poor sleep quality was defined as PSQI & gt;5. Excessive daytime sleepiness and Depression are performed with ESS and PHQ-9, respectively. Results During the 9 years, average sleep duration decreased by 21 minutes, especially more reduction on free days (workday: 7:17±1:58 vs. 7:06±1:06, p & lt;0.001; free days 8:04±2:32 vs. 7:49±1:23, p & lt;0.001). People go to sleep and wake up earlier on workday (workday 23:39±1:50 vs. 23:25±1:30, p & lt;0.001; free days 23:51±2:11 vs. 23:25±2:11, p & lt;0.001), whereas they go to bed earlier and wake up later on free days compared to past (workday 6:52±1:36 vs. 6:37±1:11, p & lt;0.001; 7:42±2:04 vs. 7:49±1:42 p =0.023). Social jetlag was increased by 5 minutes (0:46±1:35 vs. 0:51±0:52, p =0.028). There was the difference of age on the habitual sleep-wake rhythm and sleep related symptoms. Also, short or long sleep duration was associated with a significant increase in each health outcomes. Conclusion Decreased sleep duration seems to be on the rise in the general adult population, which lead to a poor health status. Interventions to promote adequate sleep is urgently needed.
