The purpose of this study was to investigate the changes in health related fitness, β-amyloid and dehydroepiandrosterone sulfate (DHEAs) concentration, in elderly women after 12 weeks of combined exercise. Subjects consisted of fourteen elderly women (control : 7, exercise : 7) whose ages were over 75 yrs and mini mental status examination (MMSE) scores were more than 24. The combined exercise program included stretching for 10 minutes, 30 minutes of low impact aerobic exercise at an intensity above 40∼59% of HRR during 1∼6 weeks and 60∼84% of HRR during 7∼12 weeks, and 20 minutes of resistance exercise composed of muscle strengthening and posture correction. The program was conducted 3 times a week for 12 weeks. We found that peakVO₂ and peakVO₂/weight significantly (P<.05) increased after combined exercise. Also β-amyloid significantly (P<.05) decreased and DHEAs concentration significantly (P2 (r=−0.929, P=0.001) and positively correlated with a change in LDL-C (r=0.799, P=0.031) in the exercise group. The change in DHEAs positively correlated with a change in peakVO₂ (r=0.705, P=0.017) in the exercise group. In conclusion, these results suggest that combined exercise in elderly women (mean age of 75-years) for 12 weeks would play a positive role in cardiopulmonary function, lipid metabolism and dementia risk factors such as β-amyloid and DHEAs.

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.

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.

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: 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.

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.

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.

Background: We used machine learning and population-based data for analyzing the determinants of sarcopenia in adult women and developing its decision support systems for various subgroups. Methods: All data was acquired from the Korea National Health and Nutrition Examination Survey, and women 18 years and older were included in this research. The variables were selected based on female characteristics and the ability to be acquired in a survey format, and were ranked by importance using Random Forest. From this ranking, four main variables were selected, age, menopause age, menarche age and number of pregnancy. A decision supporting system was constructed based on a tree randomly selected from Random Forest. Results: We defined sarcopenia as -2SD below the appendicular skeletal mass (ASM) index reference of 0.5136, and 89.87% (n = 8,610) were found non-sarcopenic and 10.13% (n = 971) were found sarcopenic. The subjects were divided into 6 groups based on menopausal status and BMI. The obese postmenopausal women had the highest number of sarcopenia, whereas the non-obese premenopausal women had the least number of sarcopenic subjects. In non-obese premenopausal women, which was considered to be at the lowest risk for sarcopenia, the most determining variable was the menarche age, followed by age and number of pregnancies. In obese and postmenopausal women, which was considered to be at the highest risk for sarcopenia, the most influential factor was the menopausal age, followed by age and menarche age. Conclusions We identified the major determinants of sarcopenia using machine learning and population-based data. This study demonstrated the strengths of the random forest as an effective decision support system for each stratified subgroup to find its own optimal cut-off points for the major variables of sarcopenia.
