PURPOSE: The aim of this study was to evaluate the influence of the mothers' native country on influenza vaccinations in adolescents in multicultural families. METHODS: Data were gathered from the 13th (2017) Youth Risk Behavior Web-Based Survey. Logistic regression analyses were conducted using a complex sample data analysis method. The participants in this study had a father who was born in Korea and a mother born outside of Korea. The sample included 481 adolescents. RESULTS: The analysis of non-adjusted confounding variables showed that influenza vaccination was higher in multicultural adolescents whose mother's native country had an annual minimum temperature less than 21℃ (odds ratio [OR]: 1.81, 95% confidence interval [CI]: 1.20~2.74). Furthermore, when the analysis was adjusted for confounding variables, an annual minimum temperature less than 21℃ in the mother's native country had a statistically significant association with influenza vaccination (OR: 2.12, 95% CI: 1.36~3.29). CONCLUSION: Multicultural adolescents belong to a socioeconomically vulnerable class, and their health promotion behaviors are influenced by their mothers' culture. Thus, healthcare providers and school nurses should provide adolescents with appropriate information related to influenza vaccination depending on their mothers' culture and their family's cultural background.

BACKGROUND: Periodic lateralized epileptiform discharges (PLEDs) are the main electroencephalograph (EEG) findings that imply the existence of acute or subacute structural lesions. The purpose of this study was to investigate the electrophysiologic characteristics of PLEDs by identifying the relationship between the current-source distribution (CSD) of PLEDs and the high signal intensity of diffusion-weighted magnetic resonance imaging (MRI; HSI-DWI) in viral encephalitis. METHODS: Six patients were enrolled. Twenty typical EEG, 1-s epochs, including the negative peak of the PLEDs, were averaged into an averaged-PLED (a-PLED). The CSD at the negative peak point of the a-PLED was located on the Talairach human brain map in each patient. The CSDs of the patients were compared with the anatomic locations of encephalitic lesions observed on diffusion-weighted MRI. RESULTS: In all patients, the locations with HSI-DWI were observed in the cortical areas. In two out of the six patients the locations of CSD and those of HSI-DWI were matched. In the other patients, they were partly matched. The matched areas were observed in the frontal, temporal, and parietal areas. The additional areas of CSD were in both insular areas, and those of HSI-DWI were in the frontal, temporal, parietal, and occipital areas. CONCLUSIONS: This study showed that the CSDs of PLEDs in viral encephalitis were mostly matched with the HSI-DWI in the cortical area of the frontal, temporal, and parietal areas. The cortical lesion itself in viral encephalitis may be part of the neural generator of PLEDs.

BACKGROUND: The voltage topography of temporal spikes has two distinct patterns, designated type I and type II; the orientation of the current-dipole source (O-CDS) of type I spikes tends to be oblique, while that of type II spikes tends to be horizontal. The purpose of this study was to identify the effects of the O-CDS of anterior temporal spikes on clinical factors including onset age, seizure frequency, secondary generalization, disease duration, intractability, polytherapy, febrile seizure, hippocampal sclerosis, and neocortical-temporal aura. METHODS: We examined the scalp electroencephalograms of 24 patients with temporal lobe epilepsy (TLE) and anterior temporal spikes. A spatiotemporal dipole model was applied to determine the O-CDS of the averaged spikes in each patient. We performed current-source analysis of multiple spatiotemporal dipole models using Brain Electrical Source Analysis software. The patients were divided into two subgroups according to their O-CDS pattern: oblique and horizontal. Clinical factors were compared between the two groups. RESULTS: Sixteen patients were classified into the oblique group, and 8 patients into the horizontal group. A neocortical-temporal aura was more commonly observed in the horizontal group (p<0.05), while drug-resistance tendencies were more commonly observed in the oblique group (p<0.1). CONCLUSIONS: The horizontal O-CDS of anterior temporal spikes may be more frequently associated with a neocortical-temporal aura than the oblique O-CDS in TLE. In addition, the oblique O-CDS pattern suggests a tendency toward drug resistance. The findings of this study imply that the oblique O-CDS pattern of anterior temporal spikes may provide additional electrophysiologic information regarding drug-resistant mesial TLE.

Ictal crying has been associated with ictal activities in the medial frontal or medial temporal area of the nondominant hemisphere. We applied current-source analysis to the interictal spikes of a patient with episodes of ictal crying without sad feelings, but fear sensation. The current sources were in the medial frontal area of both cerebral hemispheres, the temporal area and the posterior cingulate gyrus of the right hemisphere.

Alpha coma is a coma state with predominant alpha activities in electroencephalography. There are two different patterns of alpha coma, depending upon the distribution of alpha activity. The causes may vary with the distribution pattern. To clarify the difference in alpha-activity distribution, we conducted current-source analysis of the alpha-frequency band in two patients with alpha-coma caused by drug intoxication and pontine infarction, respectively. The current-source analysis of alpha-frequency bands may make it easier to distinguish the distribution patterns.

Aged people are challenged by serious complications from chronic diseases, such as mood disorder, diabetes, heart disease, and infectious diseases, which are also the most common causes of death in older people. Therefore, elderly care facilities are more important than ever. The most common causes of death in elderly care facilities were reported to be diabetes, cardiovascular disease, and pneumonia. Recently, the coronavirus disease 2019 (COVID-19) pandemic have a great impact on blind spots of safety where aged people were isolated from society. Elderly care facilities were one of the blind spots in the midst of the pandemic, where major casualties were reported from COVID-19 complications because most people had one or two mortality risk factors, such as diabetes or cardiovascular disease. Therefore, medical governance of public health center and hospital, and elderly care facility is becoming important issue of priority. Thus, remote health monitoring service by the Internet of Medical Things (IoMT) sensors is more important than ever. Recently, technological breakthroughs have enabled healthcare professionals to have easy access to patients in medical blind spots through the use of IoT sensors. These sensors can detect medically urgent situations in a timely fashion and make medical decisions for aged people in elderly care facilities. Real-time electrocardiograms and blood sugar monitoring sensors are approved by the medical insurance service. Real-time monitoring services in medical blind spots, such as elderly care facilities, has been suggested. Heart rhythm monitoring could play a role in detecting early cardiovascular disease events and monitoring blood glucose levels in the management of chronic diseases, such as diabetes, in aged people in elderly care facilities. This review presents the potential usefulness of remote monitoring with IoMT sensors in medical blind spots and clinical suggestions for applications.

Background: Ultrafiltration (UF) would enhance coagulation profiles by concentrating coagulation elements during cardiopulmonary bypass (CPB) for cardiac surgery. Methods: We retrospectively reviewed electronic medical records of 75 patients who had undergone cardiac surgery with rotational thromboelastometry-based coagulation management in a university hospital and analyzed the UF-induced changes in the maximum clot firmness (MCF) of extrinsically activated test with tissue factor (EXTEM) during CPB in 30 patients. Results: The median volume of filtered-free water was 1,350 ml, and median hematocrit was significantly increased from 22.5% to 25.5%. As the primary measure, UF significantly increased the median MCF-EXTEM from 48.0 mm to 50.5 mm (P = 0.015, effect size r = 0.44). The area under the receiver operating characteristic curve pre-UF MCF-EXTEM for discrimination of any increase of MCF-EXTEM after applying UF was 0.89 (95% CI [0.77, 1.00], P < 0.001), and its cut-off value was 50.5 mm (specificity of 81.8% and sensitivity of 84.2% in Youden’s J statistic). In the secondary analyses using the cut-off value, UF significantly increased the median MCF-EXTEM from 40.5 mm to 42.5 mm in 18 patients with pre-UF MCF-EXTEM ≤ 50.5 mm. However, it did not increase MCF-EXTEM in 12 patients with pre-UF MCF-EXTEM > 50.5 mm. There was a significant interaction between pre-UF MCF-EXTEM values and applying UF (P < 0.001 for the subgroup, P = 0.046 for UF, P = 0.003 for interaction). Conclusions Applying UF improved clot firmness, and the improvement was more pronounced when pre-UF MCF-EXTEM had been reduced during CPB.
