ABSTRACT
Postmenopause, the secretion of female hormones changes, causing excessive fat accumulation in the body and leading to chronic inflammation, which increases the incidence of cardiovascular diseases (CVD). Walking is an easily accessible daily exercise and effective non-pharmacological treatment for reducing obesity and the incidence of CVD. The aim of this study was to investigate the effect of moderate intensity walking exercises on body composition, vascular inflammatory factors, and vascular endothelial growth factor (VEGF) in postmenopausal women with obesity. Twenty-six older postmenopausal women with obesity (ages 68-72) were randomly assigned to control (n = 12, BMI 26.06 ± 1.37) or exercise (n = 14, BMI 26.04 ± 1.94) groups. Following a 12-week moderate intensity walking exercise program, we measured the participants' body composition with an InBody S10 analyzer and assessed blood sera using enzyme-linked immunosorbent assays. There was a significant clustering by weight (p < 0.01), body mass index (p < 0.01), percentage body fat (p < 0.001), high-sensitivity C-reactive protein (p < 0.05), interleukin-6, and tumor necrosis factor-α (p < 0.05) being significantly decreased in the exercise group. Although VEGF levels did not change significantly, a tendency to increase was observed in participants that exercised. Our results indicate that walking exercise may help prevent CVD in postmenopausal women with obesity by reducing obesity and vascular inflammatory factors.

ABSTRACT
This study was conducted to evaluate the efficacy and safety of Unicenta in female subjects with menopausal symptoms by analyzing the changes in the Kupperman index (primary endpoint) and hormonal changes (secondary endpoint). It was a randomized, multi-center, double-blind, parallel, non-inferiority clinical study conducted at two different tertiary medical centers. A Unicenta injection was shown to be non-inferior to Melsmon based on the Kupperman index in both the intent-to-treat and per-protocol populations (p = 0.789 and p = 0.826, respectively). Additionally, there were no statistically significant differences in hormone levels (estradiol, follicular-stimulating hormone) or in the evaluation of facial flushes. There was no statistically significant difference in the incidence rate of adverse events between the two groups (p = 0.505). The study demonstrated that Unicenta is not inferior to Melsmon in terms of the change in the Kupperman index after 12 days of injection. The efficacy and safety of Unicenta were shown, resulting in the improvement of menopausal symptoms.

OBJECTIVE: This study aimed to examine the association of circulating senescence-associated secretory phenotype proteins, secreted by senescent cells, with indicators of women's ovarian reserve. METHODS: This secondary analysis of cross-sectional baseline survey data was undertaken by the Korean Genome and Epidemiology Study Cardiovascular Disease Association Study. A total of 223 women (aged 40-82 y), without any history of oophorectomy, hysterectomy, or other medical conditions that could lower the ovarian reserve, were enrolled in this analysis. Chronological age (years), menopausal status, and serum anti-müllerian hormone (ng/mL) level were used to assess the associations among biological aging, accelerated menopausal aging, and ovarian reserve. RESULTS: Of the 223 women participants (53.4 ± 11.0 y), 147 (46.4 ± 3.9 y) and 76 (67.0 ± 6.9 y) were premenopausal and postmenopausal, respectively. Serum levels of senescence-associated secretory phenotype proteins were generally higher in postmenopausal, than in premenopausal, women. In the analyses adjusted for chronological age and body mass index, 17 senescence-associated secretory phenotype proteins were associated with menopausal status. However, in premenopausal women, no association trends with the level of anti-müllerian hormone were detected for a total of 28 senescence-associated secretory phenotype proteins. CONCLUSIONS: In a cohort of middle-aged/older women, the level of circulating senescence-associated secretory phenotype proteins indicated chronological age and menopausal status. Yet, serum levels of senescence-associated secretory phenotype protein potentially have limited predictive value for ascertaining ovarian reserve in premenopausal women.

BACKGROUND: Oxiracetam may have a modest effect on preventing cognitive decline. Exercise can also enhance cognitive function. This trial aims to investigate the effect of oxiracetam on post-stroke cognitive impairment and explore whether this effect is modified by exercise. Furthermore, the mechanisms that mediate this effect will be investigated through a neural network analysis. METHODS: This is a multicenter, randomized, double-blind, placebo-controlled phase IV trial. Patients who complained of cognitive decline 3 months after stroke and had a high risk of cognitive decline were eligible. Patients were randomly assigned to receive either 800 mg of oxiracetam or placebo twice daily for 36 weeks. After randomization, a predetermined exercise protocol was provided to each participant, and the degree of physical activity was assessed using wrist actigraphy at 4, 12, 24, and 36 weeks. Resting-state functional MRI was obtained in baseline and 36-week follow-up. Co-primary endpoints are changes in the Mini-Mental State Examination and Clinical Dementia Rating-Sum of Boxes. Secondary endpoints include changes in the NINDS-CSN VCIHS-Neuropsychology Protocol, Euro QoL, patient's global assessment, and functional network connectivity. If there is a significant difference in physical activity between the two groups, the interaction effect between physical activity and the treatment group will be examined. A total of 500 patients were enrolled from February 2018, and the last patient's final follow-up was completed in September 2022. CONCLUSION: This trial is meaningful not only to prove the efficacy of oxiracetam, but also evaluate whether exercise can modify the effects of medication and how cognitive function can be restored.

BACKGROUND: The aim of this study is to compare the surgical outcomes of single-port laparoscopic surgery (SPLS) and single-port robotic surgery (SPRS). METHODS: We retrospectively analyzed patients who underwent a hysterectomy, ovarian cystectomy, or myomectomy with SPLS or SPRS from January 2020 to July 2022. Statistical analyses were performed using the SPSS chi-square test and student's t-test. RESULTS: A total of 566 surgeries including single-port laparoscopic hysterectomy (SPLH; n = 148), single-port robotic hysterectomy (SPRH; n = 35), single-port laparoscopic ovarian cystectomy (SPLC; n = 207), single-port robotic ovarian cystectomy (SPRC; n = 108), single-port laparoscopic myomectomy (SPLM; n = 12), and single-port robotic myomectomy (SPRM; n = 56). The SPRH, SPRC, and SPRM groups had a shorter operation time than the SPLS group, although the results were not statistically significant (SPRH vs. SPLH, p = 0.134; SPRC vs. SPLC, p = 0.098; SPRM vs. SPLM, p = 0.202). Incisional hernia occurred as a postoperative complication in two patients only in the SPLH group. Postoperative Hb changes were lower in the SPRC and SPRM groups than in the SPLC and SPLM groups (SPRC vs. SPLC, p = 0.023; SPRM vs. SPLM, p = 0.010). CONCLUSIONS: Our study demonstrated that the SPRS had comparable surgical outcomes when compared to the SPLS. Therefore, the SPRS should be considered a feasible and safe option for gynecologic patients.
ABSTRACT
A randomized controlled trial (RCT) was conducted to evaluate the effect of fermented sarco oysters (FSO) on muscle strength in postmenopausal females with low muscle mass. Fifty-two female participants were randomly divided into the experiment group (EG) or control group (CG). For 12 weeks, the EG was subjected to 1000 mg of FSO extract daily while the CG consumed the placebo extract. The muscle extension and flexion at an angular velocity of 60°/s and with respect to grip strength, body composition, and muscle growth-related blood factors were measured at the baseline and after the trial. The difference in the quadriceps muscle extension at an angular velocity of 60°/s, grip strength on both the left and right side, and insulin-like growth factor-1(IGF-1) between groups were significantly higher in the EG compared with the CG. However, no differences were found in body composition, blood pyruvate, lactate, or high-sensitivity C-reactive protein (hsCRP) concentration between the two groups. In conclusion, FSO supplements may improve muscle strength in postmenopausal females with relatively reduced muscle strength without a change in muscle mass.

Estradiol (E2) treatment has been known to induce changes in food intake, energy expenditure, and weight gain. However, its direct effects on adipose tissue macrophages (ATM) in vivo are not fully understood. Thus, we aimed to explore this aspect at cellular and molecular levels in ovariectomized obese mice. We examined the changes in ATMs after eight weeks of a high-fat diet (HFD) in male, female, and ovariectomized (OVX) mice. After eight weeks, osmotic pumps were inserted into OVX mice to provide two weeks of E2 treatment. We additionally set up a vehicle Pair-Fed (PF) control group that supplied the same amount of HFD consumed by the E2-treated group. We then investigated the in vivo phenotypic changes of visceral adipose tissue (VAT) macrophages. The percentage of M1-like ATMs decreased by the anorectic effect of E2, while M2-like ATMs increased regardless of the anorexia. E2 treatment increased the expression of anti-inflammatory genes but decreased pro-inflammatory genes in VAT. Monocyte recruitment and local proliferation contributed to M2-like ATMs. Furthermore, M2-like phenotypes were induced by E2 treatment in human macrophages. E2 treatment increases M2-like macrophages and improves the tissue milieu of VAT regardless of the anorectic reaction of E2.
ABSTRACT
Chemotherapy-induced ovarian damage and fertility preservation in young patients with cancer are emerging disciplines. The mechanism of treatment-related gonadal damage provides important information for targeting prevention methods. The genomic aspects of ovarian damage after chemotherapy are not fully understood. Several studies have demonstrated that gene alterations related to follicular apoptosis or accelerated follicle activation are related to ovarian insufficiency and susceptibility to ovarian damage following chemotherapy. This may accelerate follicular apoptosis and follicle reservoir utilization and damage the ovarian stroma via multiple molecular reactions after chemotherapy. This review highlights the importance of genomic considerations in chemotherapy-induced ovarian damage and multidisciplinary oncofertility strategies for providing high-quality care to young female cancer patients.

Fertility preservation is an emerging discipline, which is of substantial clinical value in the care of young patients with cancer. Chemotherapy and radiation may induce ovarian damage in prepubertal girls and young women. Although many studies have explored the mechanisms implicated in ovarian toxicity during cancer treatment, its molecular pathophysiology is not fully understood. Chemotherapy may accelerate follicular apoptosis and follicle reservoir utilization and damage the ovarian stroma via multiple molecular reactions. Oxidative stress and the radiosensitivity of oocytes are the main causes of gonadal damage after radiation treatment. Fertility preservation options can be differentiated by patient age, desire for conception, treatment regimen, socioeconomic status, and treatment duration. This review will help highlight the importance of multidisciplinary oncofertility strategies for providing high-quality care to young female cancer patients.

OBJECTIVES: To objectively assess light physical activity (PA), moderate-to-vigorous PA (MVPA), step counts and number of 10 min MVPA bouts and their association with physical function among older adults. DESIGN: Cross-sectional design. SETTING: Urban community setting in Taiwan. PARTICIPANTS: 127 Taiwanese older adults aged over 65 years (mean age=70.8±5.3 years; 72% women). PRIMARY AND SECONDARY OUTCOME MEASURES: Triaxial accelerometers were used to measure PA variables for 10 hours/day for seven consecutive days. Then, five physical function components (handgrip strength, single-leg stance, 5-metre walk speed, timed up and go and sit-to-stand test) were measured. Multiple linear regressions were used to perform separate analyses for older men and women. RESULTS: For older women, daily MVPA time (ß: 0.39, 95% CI: 0.12, 0.64; p=0.004), daily step counts (ß: 0.46, 95% CI: 0.12, 0.78; p=0.009) and number of 10 min MVPA bouts (ß: 0.27, 95% CI: 0.001, 0.53; p=0.049) were positively associated with handgrip strength after adjusting for accelerometer wear time, sedentary time and other confounders. Furthermore, daily MVPA time was positively associated with a single-leg stance (ß: 0.25, 95% CI: 0.02, 0.49; p=0.036) and higher daily step counts were associated with shorter walking speed performance (ß: -0.31, 95% CI: -0.57, -0.001; p=0.049). None of the variables of the objectively assessed PA patterns was associated with physical function outcomes among older men due to their small sample size. CONCLUSIONS: Daily MVPA, MVPA bouts of at least 10 min and accumulated daily steps are important for improving physical function among older women. Future prospective research should establish causal associations between PA patterns and functional ability among older adults.

Endometriosis is one of the most common diseases in reproductive ages, and it affects patients' quality of life and fertility. However, few Korean guidelines are available for the evaluation and management of endometriosis. Korean Society of Endometriosis reviewed various literatures and trials, and to provide seventy-one evidence-based recommendations. This review presents guidelines for the diagnosis and management of endometriosis with emphasis on: it's role in infertility, treatment of recurrence, asymptomatic women, endometriosis in adolescents and menopausal women, and possible association of endometriosis with cancer.
ABSTRACT
PURPOSE: Ascorbic acid has been reported to have an adipogenic effect on 3T3-L1 preadipocytes, while evidence also suggests that ascorbic acid reduces body weight in humans. In this study, we tested the effects of ascorbic acid on adipogenesis and the balance of lipid accumulation in ovariectomized rats, in addition to long-term culture of differentiated 3T3-L1 adipocytes. MATERIALS AND METHODS: Murine 3T3-L1 fibroblasts and ovariectomized rats were treated with ascorbic acid at various time points. In vitro adipogenesis was analyzed by Oil Red O staining, and in vivo body fat was measured by a body composition analyzer using nuclear magnetic resonance. RESULTS: When ascorbic acid was applied during an early time point in 3T3-L1 preadipocyte differentiation and after bilateral ovariectomy (OVX) in rats, adipogenesis and fat mass gain significantly increased, respectively. However, lipid accumulation in well-differentiated 3T3-L1 adipocytes showed a significant reduction when ascorbic acid was applied after differentiation (10 days after induction). Also, oral ascorbic acid administration 4 weeks after OVX in rats significantly reduced both body weight and subcutaneous fat layer. In comparison to the results of ascorbic acid, which is a well-known cofactor for an enzyme of collagen synthesis, and the antioxidant ramalin, a potent antioxidant but not a cofactor, showed only a lipolytic effect in well-differentiated 3T3-L1 adipocytes, not an adipogenic effect. CONCLUSION: Taking these results into account, we concluded that ascorbic acid has both an adipogenic effect as a cofactor of an enzymatic process and a lipolytic effect as an antioxidant.

Mice lacking peroxisome-proliferator activated receptor-γ (PPARγ) in neurons do not become leptin resistant when placed on a high-fat diet (HFD). In male mice, this results in decreased food intake and increased energy expenditure, causing reduced body weight, but this difference in body weight is not observed in female mice. In addition, estrous cycles are disturbed and the ovaries present with hemorrhagic follicles. We observed that PPARγ was more highly expressed in astrocytes than neurons, so we created an inducible, conditional knockout of PPARγ in astrocytes (AKO). The AKO mice had impaired glucose tolerance and hepatic steatosis that did not worsen with HFD. Expression of gluconeogenic genes was elevated in the mouse livers, as was expression of several genes involved in lipogenesis, lipid transport, and storage. The AKO mice also had a reproductive phenotype with fewer estrous cycles, elevated plasma testosterone levels, reduced corpora lutea formation, and alterations in hypothalamic and ovarian gene expression. Thus, the phenotypes of the AKO mice were very different from those seen in the neuronal knockout mice, suggesting distinct roles for PPARγ in these two cell types.
ABSTRACT
PROBLEM: Inflammation is a key process in the establishment and progression of endometriosis. Resistin, an adipocytokine, has biological properties linked to immunologic functions, but its role in endometriosis is unclear. METHOD OF STUDY: Resistin gene expression was examined in eutopic and ectopic endometrial tissues from women with (n=25) or without (n=25) endometriosis. Resistin mRNA and protein levels were determined in endometrial tissue using quantitative real-time reverse transcription PCR and Western blotting, following adipokine profiling arrays. RESULTS: Resistin protein was detected in human endometrial tissues using an adipokine array test. Resistin mRNA and protein levels were significantly higher in ectopic endometrial tissue of patients with endometriosis than in normal eutopic endometrial tissue. CONCLUSION: Our results indicate that resistin is differentially expressed in endometrial tissues from women with endometriosis and imply a role for resistin in endometriosis-associated pelvic inflammation.

OBJECTIVES: This study examined the relationships between vasomotor symptoms (VMS), bone mineral density (BMD) and osteoporosis in postmenopausal women. STUDY DESIGN: A cross-sectional study was conducted of 1390 postmenopausal Korean women aged 45-65 years who attended a routine health check-up at a single institution. Their results on the Menopause Rating Scale were used to assess VMS, and moderate, severe, and very severe VMS were combined into moderate-to-severe VMS. MAIN OUTCOME MEASURES: The relationships of VMS with BMD and osteoporosis in the lumbar spine and femoral neck bone were analyzed by multivariate regression analyses. RESULTS: The mean age of all participants was 54.63 ± 4.78 years. Four hundred seventy-one (33.9%) women reported mild VMS and 344 (24.7%) reported moderate-to-severe VMS. Osteoporosis was newly diagnosed in 156 (11.2%) women. BMD levels were not significantly different among the no/mild/moderate-to-severe VMS groups, despite the significant differences in the prevalence of osteoporosis in the femoral neck bone. Women with mild VMS and those with moderate-to-severe VMS had a lower BMD than women without VMS after adjustment for age, years since menopause, years of reproductive age, BMI, insulin resistance, smoking, alcohol, steroids use, exercise, previous fracture and parental history of hip fracture. And moderate-to-severe VMS was significantly associated with the risk of osteoporosis in the femoral neck bone (OR = 2.97, 95% CI = 1.41-6.26) and in the lumbar spine (OR = 1.93, 95% CI = 1.09-3.40). CONCLUSIONS: VMS are associated with decreased BMD, and moderate-to-severe VMS in particular are independently associated with the risk of osteoporosis in otherwise healthy postmenopausal Korean women.

The aim of this cross-sectional study was to evaluate the association between vasomotor symptoms (VMS) and insulin resistance, which can be postulated by the homeostatic model assessment (HOMA) index. This study involved 1,547 Korean postmenopausal women (age, 45 to 65 years) attending a routine health check-up at a single institution in Korea from January 2010 to December 2012. A menopause rating scale questionnaire was used to assess the severity of VMS. The mean age of participants was 55.22±4.8 years and 885 (57.2%) reported VMS in some degree. The mean HOMA index was 1.79±0.96, and the HOMA index increased with an increase in severity of VMS (none, mild, moderate and severe) in logistic regression analysis (ß=0.068, t=2.665, P =0.008). Insulin resistance needs to be considered to understand the linkage between VMS and cardiometabolic disorders.
ABSTRACT
BACKGROUND: Although paratubal cysts are common, borderline paratubal cysts are extremely rare. We describe the case of a large borderline paratubal cyst in a 17-year-old adolescent female treated with laparo-endoscopic single-site surgery (LESS), and review the literature. CASE: A 17-year-old female was referred due to a large right adnexal cyst on pelvic sonogram. A CT scan showed a 19-cm cystic lesion with enhancing papillary projection along the wall. Laparo-endoscopic single-site surgery confirmed a large cystic mass that originated from the right salpinx. Right salpingectomy and right ovarian wedge resection were performed, and intraoperative frozen section analysis was conducted. The result of the frozen section analysis and final pathologic review indicated that the cyst was a serous papillary-type borderline tumor in a paratubal cyst. SUMMARY AND CONCLUSION: To the best of our knowledge, this is the first case report of a BPC treated with LESS. We suggest that minimally invasive, fertility-preserving surgery should be considered as a standard treatment of borderline paratubal cysts if patients desire future fertility.
