Comprehensive Assessment of Acute Isolated or Prominent Dysarthria in the Emergency Department: A Neuro-Emergency Expert's Experience beyond Stroke.

We investigated the clinical characteristics, neuroimaging findings, and final diagnosis of patients with acute isolated or prominent dysarthria who visited the emergency department (ED) between 1 January 2020 and 31 December 2021. Of 2028 patients aged ≥ 18 years with neurologic symptoms treated by a neuro-emergency expert, 75 with acute isolated or predominant dysarthria within 1 week were enrolled. Patients were categorized as having isolated dysarthria (n = 28, 37.3%) and prominent dysarthria (n = 47, 62.7%). The causes of stroke were acute ischemic stroke (AIS) (n = 37, 49.3%), transient ischemic attack (TIA) (n = 14, 18.7%), intracerebral hemorrhage (n = 1, 1.3%), and non-stroke causes (n = 23, 30.7%). The most common additional symptoms were gait disturbance or imbalance (n = 8, 15.4%) and dizziness (n = 3, 13.0%) in the stroke and non-stroke groups, respectively. The isolated dysarthria group had a higher rate of TIA (n = 7, 38.9%), single and small lesions (n = 10, 83.3%), and small-vessel occlusion in Trial of Org 101072 in acute stroke treatment (n = 8, 66.7%). Acute isolated or prominent dysarthria in the ED mostly presented as clinical symptoms of AIS, but other non-stroke and medical causes were not uncommon. In acute dysarthria with ischemic stroke, multiple territorial and small and single lesions are considered a cause.

Experience of a Neuro-Emergency Expert in the Emergency Department during One Year of the COVID-19 Pandemic.

We aimed to evaluate the overall clinical characteristics of patients treated by a neuro-emergency expert dedicated to the emergency department (ED) as an attending neurologist during the COVID-19 pandemic. We included adult patients who visited the ED between 1 January and 31 December 2020 and were treated by a neuro-emergency expert. We retrospectively obtained and analyzed the data on patients' clinical characteristics and outcome. The neuro-emergency expert treated 1155 patients (mean age, 62.9 years). The proportion of aged 18-40 years was the lowest, and the most common modes of arrival were public ambulance (50.6%) and walk-in (42.3%). CT and MRI examinations were performed in 94.4 and 33.1% of cases, respectively. The most frequent complaints were dizziness (31.8%), motor weakness (24.2%), and altered mental status (15.8%). The ED diagnoses were acute ischemic stroke (19.8%), benign paroxysmal positional vertigo (14.2%), vestibular neuritis (9.9%), and seizure (8.8%). The mean length of stay in the ED was 207 min. Of the patients, 55.0% were admitted to the hospital, and 41.8% were discharged for outpatient follow-up. Despite the longer stay and the complexity and difficulty of neurological diseases during the COVID-19 pandemic, the accurate diagnosis and treatment provided by a neuro-emergency expert can be presented as a good model in the ED.

Association between Serum Insulin-Like Growth Factor-1 and Neurological Severity in Acute Ischemic Stroke.

BACKGROUND AND PURPOSE: Serum insulin-like growth factor-1 (IGF-1) is known to have a neuroprotective effect. This study aimed to determine the effects of serum IGF-1 on the severity and clinical outcome of acute ischemic stroke (AIS). METHODS: This study included 446 patients with AIS who were admitted to Hallym University Sacred Heart Hospital within 7 days of stroke onset from February 2014 to June 2017. Serum IGF-1 levels were measured within 24 hours of admission. Stroke severity was measured using the National Institutes of Health Stroke Scale (NIHSS) score at admission, and the functional outcome at 3 months after symptom onset was assessed using the modified Rankin Scale score. The effects of serum IGF-1 levels on stroke severity and 3-month functional outcomes were analyzed using multivariate logistic regression analysis. RESULTS: This study evaluated 379 patients with AIS (age 67.2±12.6 years, mean±standard deviation; 59.9% males) after excluding 67 patients who had a history of previous stroke (n=25) or were lost to follow-up at 3 months (n=42). After adjusting for clinically relevant covariates, a higher serum IGF-1 level was associated with a lower NIHSS score at admission (adjusted odds ratio=0.44, 95% confidence interval=0.24-0.80, p=0.01), while there was no significant association at 3 months. CONCLUSIONS: This study showed that a higher serum IGF-1 level is associated with a lower NIHSS score at admission but not at 3 months. Further studies are required to clarify the usefulness of the serum IGF-1 level as a prognostic marker for ischemic stroke.

The Socialist Camp's North Korean Medical Support and Exchange (1945-1958): Between Learning from the Soviet Union and Independent Course.

This study focused on the socialist camp's North Korean medical support and its effects on North Korean medical field from liberation to 1958. Except for the Soviet assistance from liberation to the Korean War, existing studies mainly have paid attention to the 'autonomous' growth of the North Korean medical field. The studies on the medical support of the Eastern European countries during the Korean War have only focused on one-sided support and neglected the interactions with the North Korean medical field. Failing in utilizing the materials produced in North Korea has led to the omission of detailed circumstances of providing support. Since the review of China's support and the North Korea-China medical exchanges has been concentrated in the period after the mid-1950s, the impacts of China's medical support on North Korea during the Korean War period and the post-war recovery period have not been taken into account. In terms of these limitations, this study examined the medical activities by the Socialist camp of the Eastern European countries in North Korea after the Korean War. The medical aid teams from Hungary, Romania, Bulgaria, Czechoslovakia, Poland, and East Germany that came to North Korea in the wake of the Korean War continued to stay in North Korea after the war to build hospitals and train medical personnel. In the hospitals operated by these countries, cooperative medical care with North Korean medical personnel and medical technology education were conducted. Moreover, medical teams from each country in North Korea held seminars and conferences and exchanged knowledge with the North Korean medical field staffs. These activities by the Socialist countries in North Korea provided the North Korean medical personnel with the opportunity to directly experience the medical technology of each country. China's support was crucial to North Korea's 'rediscovery' of Korean medicine in the mid-1950s. After the Korean War, North Korea began to apply the Chinese-Western medicine integration policy, which was performed in China at that time, to the North Korean health care field through China's medical support and exchanges. In other words, China's emphasis on Chinese medicine and the integration of the Chinese-Western medicine were presented as one of the directions for medical development of North Korea in the 1950s, and the experiences of China in this process convinced North Korea that Korean medicine policy was appropriate. The decision-makers of the North Korean medical policies, who returned to North Korea after studying abroad in China at that time, actively introduced the experiences from China and constantly sought to learn about them. This study identified that a variety of external stimuli had complex impacts on the North Korean medical field in the gap between 'Soviet learning' in the late 1940s and the 'autonomous' medical development since the 1960s. The North Korean medical field was formed not by the unilateral or dominant influences of a single nation but by the stimulation from many nations and the various interactions in the process.
