The purpose of this study was to examine the influence of 12-week combined exercise program on carotid artery structure and function, and vascular endothelial growth factor (VEGF) in obese older women. All subjects were sixty years or older (66.90±4.2 years), performed the combined exercise training during 12-week consisting of aerobic exercise, band exercise, and yoga exercise for 70 minutes 3 times a week under the supervision of exercise specialist. Despite no statistically significant change in control group, percent body fat mass (3.26 %, p<.01), systolic blood pressure (6.2 mmHg, p<.05), diastolic blood pressure (5.6 mmHg, p<.001), and 10 m maximal walking time (0.56 sec, p<.05), TC (20.5 mg/dl, p<.05), and LDL-C (22.16 mg/dl, p<.05) were significantly decreased respectively after 12-week combined exercise in exercise group. In addition, sit-and-reach (3.6 cm, p<.01), oxygen uptake per weight (3.27 ml/kg/min, p<.05), VEGF (17.85 pg/dl, p<.001), and carotid artery LD (0.4 cm, p<.01), PFV (10.06 cm/sec, p<.05), EFV (6.04 cm/sec, p<.05) were significantly increased in the exercise group than in the control group. The VEGF had the significant correlation with LD (r=.389, p<.01), PFV (r=.427, p<.01), EFV (r=.264, p<.05). In conclusion, 12-week combined exercise program is effective to improve and/or physical function and body composition. And also, exercise can improve serum lipid metabolism, VEGF regulation, and carotid artery function and structure.

BACKGROUND AND PURPOSE: The purpose of this study was to investigate the impact of multi-tasking exercise on cognitive and motor function in patients with mild cognitive impairment (MCI) and cognitive normal elderly (CNE).METHODS: A total of 144 subjects were recruited from 14 regional dementia centers in Busan Metropolitan City. With the exception of 77 subjects unsuitable for the study, 67 subjects participated in the intervention. The Korean version of Mini-Mental State Examination for Dementia Screening (MMSE-DS), Subject Memory Complain Questionnaire (SMCQ), and the Korean version of the Short-Form Geriatric Depression Scale (SGDS-K) were used to determine changes in cognitive function and depressive symptoms pre-post intervention in patients with MCI and CNE, respectively. To observe changes in motor function, 5-chair sit to stand and 5-meter walking speed on the lower body strength and walking ability were also measured in both groups.RESULTS: For the MCI group, changes in cognitive and depressive symptoms on the tasks of MMSE-DS (p=0.006), SMCQ (p=0.000), SGDS-K (p=0.000) and the result of the motor function analysis on the items of 5-chair sit to stand (p=0.000), normal speed (p=0.004) and maximal speed (p=0.002) of 5-meter walking speed (p< 0.005). In the CNE group, all the items except MMSE-DS (p=0.068) and SGDS-K (p=0.095) showed statistically significant improvement.CONCLUSIONS: Multi-tasking exercise intervention, including exercise and cognitive tasks, may possibly improve the cognitive and motor function in patients with MCI and CNE.

OBJECTIVES: This study aimed to compare the efficacy of tibolone and transdermal estrogen in treating menopausal symptoms in postmenopausal women with an intact uterus.METHODS: Overall, 26 women consumed tibolone orally and 31 women received transdermal estrogen gel mixed with progestogen. The menopause rating scale (MRS) was used to assess their menopausal symptoms at their first outpatient visit and 6 months later.RESULTS: The transdermal estrogen group showed significant improvements in more items of the MRS questionnaire. There was a favorable change in body weight in the transdermal estrogen group compared with that in the tibolone group. Depressive mood, irritability, physical and mental exhaustion, sexual and bladder problems, and joint and muscular discomfort improved only in the transdermal estrogen group, whereas heart discomfort and vaginal dryness improved only in the tibolone group. Nevertheless, the intergroup differences in each item were insignificant after adjusting for body mass index and hypertension, which differed before treatment.CONCLUSIONS: Both the therapeutic options improved menopausal symptoms within 6 months of use. However, transdermal estrogen appeared to be more effective in preventing weight gain in menopausal women than tibolone.

Background:
Although menopause is considered a risk factor for depression, no association has been established between the risk of suicidal ideation and age at menopause. This study aimed to evaluate the association between age at menopause and suicidal ideation in middleaged menopausal Korean women.
Methods:
This cross-sectional study used data from the Korea National Health and Nutrition Examination Survey (2013–2018). Women aged 40–65 years were divided into the following three categories: primary ovarian insufficiency (POI), early menopause, and menopause, according to age at natural menopause (< 40, 40–45, and > 45 years, respectively). Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9).
Results:
Among 2,232 menopausal women, 25 (1.1%) experienced POI and 114 (5.1%) experienced early menopause. The PHQ-9 items that pertained to low self-esteem and suicidal ideation scored higher in women with POI than in those who experienced menopause after 45 years of age. The prevalence of suicidal ideation differed significantly according to age at menopause (POI, 30.0%; early menopause, 12.7%; menopause, 8.0%; P = 0.016). Logistic regression analysis revealed that POI was significantly associated with suicidal ideation after the adjustment for age, body mass index, and education, household income, and walking levels (odds ratio, 4.2; 95% confidence interval, 1.0–17.7).
Conclusion
Korean middle-aged women with POI were more likely to have suicidal ideation than those who experienced menopause at 45 years or above, despite not being diagnosed with major depressive disorder.

Background:
and Purpose: The aim of this study was to investigate the effects of multicomponent exercise on cognitive function, depression, and quality of life in elderly individuals.
Methods:
This study prospectively recruited 605 participants, and constructed an exercise pyramid comprising even distributions of daily physical activities, aerobic exercise, musclestrengthening exercise, flexibility exercise, balance exercise, and activities that subjects could perform while sitting down. The exercise program was divided into six stages according to the participant’s level of frailty. The 12-week exercise program intervention was conducted once yearly.
Results:
The exercise regimen was followed by 402 of the 605 enrolled participants, giving a dropout rate of 33.6%. The 27-month exercise program was completed by 60 participants.The scores for the Mini Mental State Examination for dementia screening (MMSE-DS), short form of the Geriatric Depression Scale, World Health Organization Quality of Life Assessment (WHOQOL-BREF), International Physical Activity Questionnaire (IPAQ), fear of falling, handgrip strength, and walking speed were improved after the exercise intervention. The analysis of frailty revealed that participants in the frail group showed greater improvements for the MMSE-DS, WHOQOL-BREF, IPAQ, fear of falling, handgrip strength, and walking speed.
Conclusions
Individually customized, multicomponent exercise programs lead to improved levels of cognitive function, depression, and quality of life, especially among those who are more frail.

OBJECTIVE: To develop the Korean version of the Kessler Foundation Neglect Assessment Process (KF-NAP), which enables a more functional assessment of unilateral spatial neglect, by first translating it into Korean and then statistically standardizing it. METHODS: Two rehabilitation specialists translated the KF-NAP into Korean. The entire process of administering the Korean KF-NAP to 30 patients with brain disease was video-recorded. Five occupational therapists from 4 university hospitals nationwide evaluated the 30 video-recorded examination cases. We analyzed inter- and intra-reliabilities of the Korean KF-NAP using the intraclass coefficient and Pearson correlation coefficient. Internal consistency reliability of the assessment categories was also examined using Cronbach's alpha coefficient. RESULTS: For the construct validation study, the Korean KF-NAP was strongly correlated with the Albert's test and letter cancellation test (r ≥ 0.8; p < 0.05). The intraclass correlation coefficients for the first and second assessments of the Korean KF-NAP were 0.973 and 0.982, respectively, showing high reliability (p < 0.05). The intra-rater reliabilities exceeded 0.9 (p < 0.05), and Cronbach's alpha coefficient exceeded 0.8, showing internal consistency reliability. CONCLUSION: The Korean KF-NAP is a reliable and valid instrument for assessing hemispatial neglect symptoms in patients with brain diseases.

PURPOSE: To investigate whether autologous platelet-rich plasma (PRP) treatment can improve regeneration of the endometrium in an experimental model of ethanol-induced damage. MATERIALS AND METHODS: Sixty female Sprague-Dawley rats were randomly assigned into three groups: control group, ethanol group, and PRP-treated group (administration of 0.25 mL of PRP into both uterine cavities 72 hours after ethanol injection). After 15 days of endometrial damage, all the animals were sacrificed during the estrous cycle, and samples were taken from the mid-uterine horn. Functional and structural recovery of the endometrium was analyzed by hematoxylin-eosin (H&E) and Masson trichrome (MT) staining, real-time polymerase chain reaction (PCR) assay, and immuno-histochemical (IHC) analyses. RESULTS: H&E and MT staining confirmed significantly decreased fibrosis and increased cellular proliferation in the PRP-treated group, compared to the ethanol group. The endometrial areas in the ethanol and PRP-treated groups were 212.83±15.84 µm² and 262.34±12.33 µm² (p=0.065). Significantly stronger IHC expression of cytokeratin, homeobox A10 (HOXA10), vascular endothelial growth factor (VEGF), and Ki-67 was found in the PRP-treated group, compared to the ethanol group. In real-time PCR analyses, interleukin-1β mRNA was down-regulated, while c-Kit mRNA was up-regulated, in the PRP-treated group, compared to the ethanol group. CONCLUSION: Intrauterine administration of autologous PRP stimulated and accelerated regeneration of the endometrium and also decreased fibrosis in a murine model of damaged endometrium.

Background:
To analyze the factors associated with women's vasomotor symptoms (VMS) using machine learning.
Methods:
Data on 3,298 women, aged 40–80 years, who attended their general health check-up from January 2010 to December 2012 were obtained from Korea University Anam Hospital in Seoul, Korea. Five machine learning methods were applied and compared for the prediction of VMS, measured by the Menopause Rating Scale. Variable importance, the effect of a variable on model performance, was used for identifying the major factors associated with VMS.
Results:
In terms of the mean squared error, the random forest (0.9326) was much better than linear regression (12.4856) and artificial neural networks with one, two, and three hidden layers (1.5576, 1.5184, and 1.5833, respectively). Based on the variable importance from the random forest, the most important factors associated with VMS were age, menopause age, thyroid-stimulating hormone, and monocyte, triglyceride, gamma glutamyl transferase, blood urea nitrogen, cancer antigen 19-9, C-reactive protein, and low-density lipoprotein cholesterol levels. Indeed, the following variables were ranked within the top 20 in terms of variable importance: cancer antigen 125, total cholesterol, insulin, free thyroxine, forced vital capacity, alanine aminotransferase, forced expired volume in 1 second, height, homeostatic model assessment for insulin resistance, and carcinoembryonic antigen.
Conclusion
Machine learning provides an invaluable decision support system for the prediction of VMS. For managing VMS, comprehensive consideration is needed regarding thyroid function, lipid profile, liver function, inflammation markers, insulin resistance, monocyte count, cancer antigens, and lung function.
