  • Background: Due to aging, blood flow rate decreases, also posture and chewing habit may be changed. Objective: To identify that changes in blood velocity in the common carotid arteries (CCAs) in old persons with unilateral chewing habit (UCH) and forward head posture (FHP) in the elderly. Design: An observational cross-sectional study. Methods: Chewing habits, FHP, and CCAs velocities were assessed in 85 elderly subjects. Chewing habits were measured by visual observation. CCAs measured the peak systolic velocity (PSV), end-diastolic velocity (EDV), minimum diastolic velocity, and resistivity index. The subjects were divided into UCH and bilateral chewing habit groups depending on chewing habit. The subjects were also divided into >49 degrees and <49 degrees for comparison of blood flow between the left and right CCAs. Results: In the UCH, the chewing side had significantly higher EDV (P=.003), PSV (P=.023) than the non-chewing side. There was no significant difference in velocity between the CCAs in the FHP. Conclusion: This study shows that the blood flow velocity of the chewing side of UCH was higher, and unilateral chewing affects the CCAs velocity and thus highlight the importance of chewing habit in the elderly than head posture.

  • Objectives: The purpose of this study was to characterize Indonesian women's knowledge of HIV/AIDS and to investigate the effects of socio-demographic characteristics thereupon with the goal of supporting the prevention and early detection of HIV/AIDS. Methods: This cross-sectional study was conducted using secondary data from the standard Indonesian Demographic and Health Survey (IDHS) in 2012. A total of 34 984 subjects ranged in age from 15 years to 49 years. Data were analyzed using the chi-square test and logistic regression to identify the effects of socio-demographic characteristics on Indonesian women's knowledge of HIV/AIDS. Results: All socio-demographic characteristics except marital status were related to knowledge of HIV/AIDS among Indonesian women in the univariate analysis (p<0.05). Multivariate analysis revealed that only age group, education level, location of residence, and wealth index were related to Indonesian women's knowledge of HIV/AIDS (p<0.05). Conclusions: Indonesian women's insufficient knowledge related to HIV/AIDS shows that the provision of accurate and comprehensive information related to HIV/AIDS are components of prevention and control interventions that should be improved. With greater knowledge, women are expected to be more likely to determine their own and their partners' human immunodeficiency virus status and to take appropriate preventive steps.

  • The relationship between obstructive sleep apnea (OSA) and diverse types of pain conditions have been proposed. However, no consensus on the relationship between OSA and painful temporomandibular disorders (TMDs) has been established. Therefore, this systematic review has been conducted to review the existing literatures and provide comprehensive synthesis of such literatures about OSA and painful TMDs using the evidence-based methodology. A literature search was conducted using two electronic databases, Scopus, and PubMed. Risk of bias was assessed using the risk-of-bias assessment tool for non-randomized study version 2.0. A total of 158 articles were screened from the initial search and eventually, 5 articles were included in this systematic review. One study adopted both the longitudinal prospective cohort and case-control designs and other 4 articles adopted the cross-sectional design. Two studies employed polysomnography (PSG) for the diagnosis of OSA and mentioned the results from the PSG. All cross-sectional studies demonstrated higher OSA prevalence among patients with TMD, and one cohort study suggested OSA as a risk factor for TMD. OSA appears to have potential influences on the development of TMD; however, the role of TMD in the development of OSA remains to be unknown owing to the lack of high-quality evidences.

  • Purpose: With the first generation of marriage-based immigrant women in East Asia now reaching their middle or old age, the need to focus investigations on their health-related quality of life has arisen. This study aimed to examine the extent to which physical and mental health, and psychosocial variables can predict health-related quality of life among Japanese middle-aged immigrant women. Methods: This study has a descriptive cross-sectional design. A convenience sample of 197 Japanese middle-aged marriage-based immigrant women from two regions of South Korea were recruited between December 2017 and March 2018. Participants completed self-administered questionnaires on health-related quality of life, menopausal symptoms, depression, perceived health status, disease morbidity, social support, and acculturation. The data were analyzed using hierarchical multiple regression. Results: Depression was the strongest predictor of health-related quality of life, followed by perceived health status, social support, and household income. Menopausal symptoms, presence of disease, and acculturation appeared to have no additional impact on participant's health-related quality of life. Conclusion: In times of rapid growth of global migration and the aging of immigrants in new destination countries, nursing interventions and public health policies for aging marriage-based immigrant women should be prioritized to improve their mental health by facilitating social support and disease management. In addition, social and employment policies that can help immigrant women transition to a healthy midlife are needed.

  • Objective: The purpose of this study was to compare and analyze the effects of arch support taping on static balance, static/dynamic foot contact area, and ground reaction force during walking according to the types of elastic tapes with mechanical elasticity differences. Design: Cross-sectional study Methods: Twenty-six participants selected for flexible flat feet through the navicular drop test were randomly assigned to non-taping, Dynamic-taping, and Mechano-taping conditions. Static balance and foot contact area were compared in the standing posture according to arch support taping conditions, and foot contact area and ground reaction force were compared during walking. Results: There was no significant difference in static balance according to the taping condition in the standing position, but the foot contact area in the Mechano-taping condition showed a significant decrease compared to the non-taping condition (p<0.05). The foot contact area during walking significantly decreased in the Dynamic-taping and Mechano-taping conditions (p<0.05), but there was no significant difference between the ground reaction force. Conclusions: Based on the results of this study, it was confirmed that among the types of elastic taping, arch support taping using dynamic taping and Mechano-taping has the effect of supporting the arch with high elastic recovery. Any type of elastic tape can be used for arch alignment in flexible flat foot.

  • Sarcopenia and myosteatosis can increase the risk of adverse effects in dogs and humans. However, such imaging study results for evaluating sarcopenia and myosteatosis in small dogs have not yet been available. The objective of this study was to assess age-related changes according to the breed in epaxial muscle cross-sectional area (CSA) and fat infiltration using CT to evaluate sarcopenia and age-related myosteatosis in small breed dogs. In 144 dogs (92 Maltese dogs, 27 Poodle dogs, and 25 Shih Tzu dogs), Hounsfield Unit (HU) values and CSA of left epaxial muscle were measured at the thirteenth thoracic vertebral level on non-contrast transverse CT images. Differences in HU values and CSA according to age and breed were analyzed. The geriatric group (≥12 years) had significantly lower HU values of epaxial muscle than mature adult group (2 to 6 years) of all breeds. The geriatric group had significantly lower CSA of epaxial muscle than mature adult and senior groups (7 to 11 years) of Maltese dogs. HU values of epaxial muscle were not significantly different among all age groups of all breeds. Maltese dogs had significantly lower CSA of epaxial muscle than Poodle and Shih Tzu dogs in all age groups. Results of this study showed that as age increased in small breed dogs, muscle mass and density decreased.

  • PURPOSE: This research investigated clinical hazardous components and analyzed the proportion of sarcopenia among young Korean women. METHODS: The cross-sectional study included 1,236 women aged 20 to 29 years, categorized into two groups according to their skeletal muscle mass index (SMI). Of these, 20 participants were placed in the sarcopenia group, while 1,216 were included in the normal group. The analysis involved hazardous components including body dimensions, clinical indicators, and behavioral trait variables: height, weight, body mass index, waist circumference, skeletal muscle mass index, systolic and diastolic blood pressure, blood laboratory tests assessing fasting glucose, triglycerides, total cholesterol, as well as smoking habits and alcohol consumption. Complex sampling analysis was used to analyze the proportion and hazardous components of sarcopenia. RESULTS: The proportion of sarcopenia was at 1.76% (95% of CI: 1.08-2.83). Anthropometric measurements, such as height, BMI, and WC, exhibited significant differences between the groups (p < .05). However, there was no significant difference in weight (p > .05) between the two groups. Among the clinical indicators, SBP, DBP, FBG, serum triglycerides, and total TC found to be significant hazardous components for sarcopenia within both groups (p < .05). Smoking status as a behavioral trait was significant as well (p < .05), unlike alcohol consumption (p > .05). CONCLUSION: This study discerned both the proportion of sarcopenia and the hazardous components associated with it among community-dwelling women of a young age.
