Background: Contents of bioactive substances extractable from different parts of terrestrial plants vary enormously. Aim: To ascertain that parts of Withania somnifera other than its roots can also be used for prevention and cure of unavoidable stress triggered central hypersensitivity to pain. Material and Methods: Groups of male or female mice treated either with Withania somnifera extracts or with metformin, aspirin, imipramine, diazepam and niacin for 11 consecutive days were subjected to "foot-shock stress-induced hyperthermia" and "hot plate" tests on the 1st, 5th, 7th, and 10th days of the experiments. On the 11th day, they were subjected to tail suspension test and on 12th day pentobarbital hypnosis test. Results: Except for diazepam and imipramine, protective effects of all other tested drugs as well as of the Withania somnifera extracts against stress-induced central hypersensitivity to pain were accompanied by their preventive effects against foot-shock stress-induced body weight losses. All observed stress response suppressing effects of all test agents increased with increasing numbers of treatment days. However, mean duration of pentobarbital-induced sleep was shorter in the extracts treated groups and longer in the diazepam treated ones only. Conclusions: Reported observations reveal that pharmacological activity profile of Withania somnifera extracts in male and female mice are almost identical, and are not like those of several drugs currently often prescribed for the treatment of diabetes-associated comorbidities. Withanolides are not the only extractable bioactive constituents of Withania somnifera. The described bioassay system is well suited for pharmacological standardization of diverse types of Withania somnifera extracts.

Objective: Shift work including night work is known to be harmful to the health of nurses. This study was conducted in order to systematically review the academic literature on the health effects of working time patterns, including shift work or night work, among Korean nurses and propose a research direction for the future. Methods: We searched online academic databases to find relevant papers in domestic and international journals using the keyword terms 'shift work', 'night work', 'night shift', 'work shift', 'nurse', and 'Korea', and reviewed a total of 36 articles. Results: As a result of this literature review, more than half of the articles were found to investigate the health effects between shiftwork and non-shiftwork nurses. A few studies considered the shift type(n=6), frequency of night shift(n=4), and shiftwork duration(n=3) as working time patterns. These studies focused mainly on mental health(n=18) or sleep(n=15). Conclusions: Based on the review results obtained from this study, it is necessary to assess working time patterns of Korean nurses using a variety of variables including night-work-related factors, and various health outcomes should be examined considering the confounder.
BACKGROUND: Children with significant adenotonsillar hypertrophy (ATH) may show right ventricular (RV) dysfunction. We aimed to evaluate RV dysfunction in such children before adenotonsillectomy by evaluating peak longitudinal right atrial (RA) strain (PLRAS) in systole. PLRAS, electrocardiogram (ECG) and conventional echocardiographic parameters were compared to distinguish children with significant ATH with sleep-related breathing disorder (ATH-SRBD) from controls. METHODS: Fifty-six children (23 controls and 33 children with ATH-SRBD without symptoms of heart failure) were retrospectively studied. Preoperative echocardiograms and ECGs of children with ATH-SRBD who underwent adenotonsillectomy were compared to those of controls. Available postoperative ECGs and echocardiograms were also analyzed. RESULTS: Preoperatively, prolonged maximum P-wave duration (Pmax) and P-wave dispersion (PWD), decreased PLRAS, and increased tricuspid annulus E/E' were found in children with ATH-SRBD compared to those of controls. From the receiver operating characteristic curves, PLRAS was not inferior compared to tricuspid annulus E/E', Pmax, and PWD in differentiating children with ATH-SRBD from controls; however, the discriminative abilities of all four parameters were poor. In children who underwent adenotonsillectomy, echocardiograms $1.2{\pm}0.4$ years after adenotonsillectomy showed no difference in postoperative PLRAS and tricuspid annulus E/E' when compared with those of the preoperative period. CONCLUSIONS: Impaired RA deformation was reflected as decreased PLRAS in children with ATH-SRBD before adenotonsillectomy. Decreased PLRAS in these children may indicate subtle RV dysfunction and increased proarrhythmic risk. However, usefulness of PLRAS as an individual parameter in differentiating preoperative children with ATH-SRBD from controls was limited, similar to those of tricuspid annulus E/E', Pmax, and PWD.
Purpose: This study was performed to assess the level of blood glucose and to identify poor glycemic control groups among patients with type 2 diabetes mellitus (DM). Methods: Data of 1,022 Korean type 2 DM patients aged 30-64 years were extracted from the Korea National Health and Nutrition Examination Survey VII. Complex samples analysis and a decision-tree analysis were performed using the SPSS WIN 26.0 program. Results: The mean level of hemoglobin A1c (HbA1c) was 7.22±0.25%, and 69.0% of the participants showed abnormal glycemic control (HbA1c≥6.5%). The characteristics of participants associated with poor glycemic control groups were presented with six different pathways by the decision-tree analysis. Poor glycemic control groups were classified according to the patients' characteristics such as period after DM diagnosis, awareness of DM, sleep duration, gender, alcohol drinking, occupation, income status, low density lipoprotein-cholesterol, abdominal obesity, and number of walking days per week. Period of DM diagnosis with a cut-off point of 6 years was the most significant predictor of the poor glycemic control group. Conclusion: The findings showed the predictable characteristics of the poor glycemic control groups, and they can be used to screen the poor glycemic control groups among adults with type 2 DM.
Objectives: This study examined the changes in dietary habits, the prevalence of chronic diseases, and mental health problems in the regional areas of the Republic of Korea before and after the COVID-19 pandemic to provide evidence of the status of regional health inequalities. Methods: This study analyzed Korean adults aged 19 or older who participated in the Korea Community Health Survey (n = 686,708) and Consumer Behavior Survey for Foods (n = 19,109) from 2018 to 2020. The participants were classified according to their residence area (Seoul metropolitan area, Metropolitan cities, Provinces); 2018-2019 were defined as before COVID-19, and 2020 as after COVID-19. The dietary behaviors, chronic diseases, and mental health problems were measured using a self-report questionnaire. Results: After COVID-19, the eating-out usage rate in the Seoul metropolitan area and Provinces decreased compared to before COVID-19 (P < 0.001), and when responding that they eat out, the frequency of eating out with household members in the Seoul metropolitan area increased (P = 0.024). The deliveries/takeout usage rate in the Provinces decreased after COVID-19 compared to before (P < 0.001). After COVID-19, the prevalence of obesity decreased in all regions (P < 0.001), and the prevalence of hypertension increased significantly in the Provinces (P = 0.015). The prevalence of diabetes mellitus increased continuously before and after COVID-19 in all regions (P < 0.002). High-risk subjective stress levels increased significantly in the Seoul metropolitan area (P < 0.001), and sleep duration significantly increased in all regions (P < 0.001). Major depressive disorder was reduced significantly in Metropolitan cities (P = 0.042) and Provinces (P < 0.001). Conclusions: After the COVID-19 pandemic, the prevalence of chronic diseases and mental health problems showed regional differences along with changes in dietary habits. It is necessary to reflect the regional differences in dietary habits in future policies resolving regional health inequalities.
Objectives: Screen time refers to the time spent using screen media, such as televisions, smartphones, computers, or tablets. Excessive exposure to screen media has been reported to negatively impact young children's health and development, including overweight, short sleep duration, and language delays. This study examined the association of screen time and mealtime media use with dietary behaviors among preschool children. Methods: A cross-sectional survey was conducted on parents of children aged three to five years using the online questionnaires of the Nutrition Quotient for Preschoolers (NQ-P) and the Dietary Screening Test (DST). Data from 261 children's parents were analyzed. Results: Of the 261 children, 96.9% used screen media, 55.6% used screen media for two hours or more daily, and 30.7% were exposed to screen media during meals. The NQ-P scores were significantly lower in the children with longer screen time and mealtime media use. Children who used screen media for two hours or more and those exposed to screen media during meals consumed kimchi less frequently and confectionery and sugar-sweetened beverages more frequently than children who used less than two hours and were not exposed to screen media during meals. In addition, they were more likely to be picky about food, refuse to eat, and less likely to feed themselves than children with shorter screen time and no mealtime media use. Conclusions: This study reported an association between unhealthy dietary behaviors, feeding difficulties, and screen time and mealtime media use among preschool children. Further research should explore effective strategies for reducing children's screen time.
Objectives: The purpose of this study was to report a case of a woman with intractable hiccups after a traffic accident through Korean medicine treatment. Methods: A combination of treatments, including herbal medicine (Soshiho-tang), pharmacopuncture, acupuncture, Chuna, cupping, and moxibustion, was administered to the patient for 21 days. The frequency and duration of hiccups, the degree of body shaking, and total sleep time were measured daily. The accompanying symptoms were measured daily using the Visual Analogue Scale. Results: After Korean medicine treatment, Hiccup symptoms disappeared. Further, the degree of clinical symptoms and QOL improved significantly after Korean medicine treatment. No adverse events were observed. Conclusions: This study suggests that Korean medicine treatment can be an effective treatment for intractable hiccups after traffic accidents.

Objectives: Parkinson's disease (PD) is currently the most rapidly increasing degenerative brain disease due to population aging and westernization of lifestyle. Levodopa is the most commonly used drug to manage PD symptoms. However, levodopa has a problem in that the wearing-off phenomenon occurs as the duration and dose of administration increase. In order to investigate the wearing-off phenomenon in PD patients and devise countermeasures, we conducted a questionnaire survey in Korea. Methods: For the study, a questionnaire with a total of seven items was prepared. Part IV of the MDS-UPDRS (Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale) and the WOQ-9 (9-symptom Wearing-off Questionnaire) were used as references. Results: Of the 48 patients who completed the questionnaire, all 47 patients who completed the questionnaire experienced the wearing-off phenomenon. Only one of the patients diagnosed with PD a year ago did not experience the wearing-off phenomenon. Patients frequently mentioned a lack of sleep and stress as aggravating factors for wearing-off. They also stated that in order to resolve the off-state, they walked, massaged, warmed up the body, stretched and exercised. Conclusions: Because wearing-off is such a common occurrence, it is thought necessary to develop wearing-off prevention and resolution measures that PD patients can use in their daily lives.
Purpose : This study aimed to identify factors influencing the quality of life of family caregivers of intensive care unit (ICU) patients. Methods : We conducted a study using a cross-sectional design. The study involved 109 family caregivers of ICU patients at a university-affiliated hospital in Gyeonggi-do, South Korea. Data were collected through self-report questionnaires between July 2020 and April 2021 and analyzed using descriptive statistics, independent t-tests, one-way ANOVA, Pearson's correlation coefficients, and multiple regression analysis. Results : The study revealed significant differences in quality of life based on economic status (F=11.63, p<.001), cohabitation with patients (t=-2.04, p=.044), sleep duration after patient's admission to the ICU (t=-2.48, p =.025), and subjective health status (F=30.06, p<.001). There were significant negative correlations observed between quality of life and post-traumatic stress symptoms (r=-.38, p<.001) as well as caregiver burden (r=-.46, p<.001). Factors affecting quality of life were subjective health status, economic status, and caregiver burden (adj. R2=0.52, F=15.64, p<.001). Conclusion : These findings underscore the need to develop and implement intervention programs tailored to the health conditions and economic status of family caregivers, with a focus on alleviating caregiver burden. Such initiatives are essential to ultimately improve the quality of life for family caregivers of ICU patients.
The purpose of this study was to investigate the sociopsychological factors which might influence the course of the temporomandibular disorders and to develop models for prediction of treatment outcome related to pain, dysfunction and sound. For this study, 268 patients with temporomandibular disorders were selected from the patients presented to department of Oral Medicine, Wonkwang university dental hospital. Chief complaints of these subjects were largely grouped into three categories such as pain, dysfunction and sound, and 10 cm visual analogue scale(VAS) was used to record the state of the three complaints every visit and Treatment Index(VAS TI) was calculated from VAS. All the forty-two items obtained from clinical examination or questionnaire were statistically processed with $SPSS^{(R)}$ windows. The results of this study were as follows: 1. The items showed a difference between male and female subjects were maximum mouth opening, palpation score, jaw jerk during mandibular movement, and sleep disturbance. Among questionnaires such as SRRS, HAD scale and PSQI, the HAD scales showed the most highly significant correlation with the each scale item of the SCL-90R. 2. Among the groups classified by VAS TI, the group with the lowest VAS TI showed the highest VAS score in the start of treatment but showed the lowest score in the end of treatment, without respect to the type of chief complaint. From these results, it is assumed that the active treatment duration for the subjects with lower VAS score in the first visit would be longer than the subjects with higher score with the somewhat poor treatment outcome. 3. With regard to all the three complaints, the items showing significant effect in the model for prediction of treatment outcome were from questionnaire, except one item, maximum mouth opening, which suggest that the sociopsychological factors would be strongly related to development and progress of the symptoms.
