Correlation of Sarcopenic Obesity on Various Cardiometabolic Risk Factors and Fracture Risk in Mid-Aged Korean Women

Objectives@#This study aimed to investigate the correlation of sarcopenic obesity with various cardiometabolic risk factors and fracture risk in middle-aged Korean women. @*Methods@#In this cross-sectional study, the medical records of 1,775 women who had visited Pusan National University Hospital for routine health screenings from 2010 to 2016 were reviewed. The patients were divided into four groups as follows: group 1, nonsarcopenic, nonobese (NS-NO); group 2, nonsarcopenic, obese (NS-O); group 3, sarcopenic, nonobese (S-NO); and group 4, sarcopenic, obese (S-O). Each patient was assessed based on self-reported questionnaires and individual interviews with a healthcare provider. The Fracture Risk Assessment Tool (FRAX) was used to assess bone fracture risk. @*Results@#Postmenopausal women accounted for 68.5% of the total patient population. The proportion of each group was as follows:NS-NO, 71.2%; NS-O, 17.9%; S-NO, 10.2%; and S-O, 0.7%. Statistical analysis of various parameters associated with metabolic and cardiovascular risks revealed that the S-O group had more patients with hypertension, diabetes, osteopenia, and metabolic syndrome.The FRAX scores were significantly higher in the S-O group than in other groups. @*Conclusions@#Middle-aged women with obesity and reduced muscle mass, known as sarcopenic obesity, are at increased risk of hypertension, diabetes, and metabolic syndrome. Furthermore, sarcopenic obesity, individual cardiometabolic risks, and menopause can increase the bone fracture risk.

Two Cases of Primary Ovarian Insufficiency Accompanied by High Serum Anti-Müllerian Hormone Levels and Preservation of Ovarian Follicles

Primary ovarian insufficiency (POI) is defined as the presence of amenorrhea for ≥ 4 months accompanied by evidence of two serum follicle-stimulating hormone levels in the menopausal range in women aged < 40 years. Anti-Müllerian hormone (AMH) has been recognized as the most reliable marker of ovarian reserve status, and its serum level is very low or undetectable in women with POI.Here we report two cases of patients who were diagnosed with POI despite high serum AMH levels and preservation of ovarian follicles, as revealed by ultrasound. In addition, we have presented a review of the current literature regarding this condition.

Impact of menopause on the women's health

Menopause is a consequence of loss of ovarian function. Withdrawal of estrogen level cause various menopausal symptoms. Change in the estrogen level can affect large areas of body target, causing atrophy of tissues and metabolic modifications with psychological and sexual changes that are variably experienced by individual woman. Short-term consequences of estrogen deprivation include vasomotor symptoms and urogenital atrophy. Long-term consequences of estrogen deprivation include cardiovascular disease, bone loss and osteoporosis, cognitive decline and Alzheimer's disease.

A Rare Case of an Autoamputated Ovary with Mature Cystic Teratoma

Autoamputated ovary with mature cystic teratoma (MCT) is a rarely reported gynecologic entity with an unknown prevalence. A 34-year-old woman referred to our clinic for presumed left ovarian tumor. Pelvic examination, ultrasonography and computed tomography scan revealed a 5-cm, cystic ovarian mass with calcification and fat component, and tumor markers were as follows, cancer antigen (CA) 125; 10.4 U/mL, CA19-9; 2 U/mL. Laparoscopy was performed. The mass was identified in the left adnexal region without any ligamentous or direct connection with the pelvic organs. The right ovary was normal. However, the left ovary and the tube could not be identified in its proper anatomical location. The mass was successfully removed with sharp and blunt dissection. A review of histopathologic study revealed a MCT. The patient became pregnant within seven months and gave birth to a healthy baby by cesarean section. We present a rare case of an autoamputated ovary with MCT.

Lymphoepithelioma-like carcinoma of the uterine cervix

Lymphoepithelioma-like carcinoma (LELC) of the uterine cervix is exceedingly uncommon. We herein report a rare case of cervical LELC. A 45-year-old woman was admitted to gynecology department with vaginal bleeding for one month. Liquid-based cytology revealed atypical endometrial cells, not otherwise specified on her cervix. On a hysteroscopy, an endocervical mass was identified and the pathologic result was consistent with poorly differentiated squamous cell carcinoma. Magnetic resonance imaging and positron emission tomography with 2-deoxy-2-[fluorine-18] fluoro-D-glucose integrated with computed tomography revealed a 3.1-cm endocervical mass without distant metastasis or enlarged lymph nodes. The International Federation of Gynecology and Obstetrics stage was IB1. A radical hysterectomy and bilateral pelvic lymph node dissection were performed. The pathologic diagnosis was a poorly differentiated carcinoma, showing features of LELC. She has been followed for 8 months without adjuvant treatment since the surgery, during which time there has been no evidence of tumor recurrence or metastasis.

Non-puerperal Uterine Inversion Presented with Hypovolemic Shock

We report a non-puerperal uterine inversion with nulliparous women caused by huge pedunculated submucosal fibroid. Massive bleeding from protruding mass through vagina brought the heart to stop in 42-year-old nulliparous woman. She became cardiopulmonary resuscitation survivor in emergency room and then underwent laparotomy which ended in successful myomectomy rather than hysterectomy considering her demand for future fertility. Meticulous and adequate fluid therapy and transfusion was also administered to recover from hypovolemic status. Pathologic report confirmed benign submucosal fibroid with degeneration, necrosis and abscess formation. Thus, clinician should be aware of uterine inversion when encountered with huge protruding vaginal mass and consider uterus-preserving management as surgical option when the future fertility is concerned.

The association between oxidative stress and bone mineral density according to menopausal status of Korean women

OBJECTIVE: The aim of this study is to investigate the association between oxidative stress and bone mineral density (BMD) according to menopausal status of Korean women. METHODS: A total of 2,232 women who visited to the health promotion center at Pusan National University Hospital between 2010 and 2014 were included in this cross-sectional study. Laboratory tests, such as uric acid, albumin, total bilirubin, which were evaluated as a natural antioxidants. Homocysteine also was evaluated as a factor associated with oxidative stress. Correlation analyses and partial correlation coefficient between BMD scores and laboratory parameters associated with oxidative stress according to menopausal status were performed with Pearson test. RESULTS: By correlation analysis, uric acid had only positive correlation with femur and lumbar BMD in premenopausal and postmenopausal group. But albumin and bilirubin, which were the other natural antioxidants, had no correlation with BMD except total bilirubin with femur BMD in postmenopausal group. Homocysteine had negative correlation with femur BMD in postmenopausal group. But there were different results in partial correlation coefficient adjusted by age and BMI. In premenopausal group, uric acid was still positive correlation with femur and lumbar BMD, whereas in postmenopausal group homocysteine had no correlation with femur BMD, total bilirubin and uric acid had no correlation with lumbar BMD. At the multiple logistic regressions, only age and menopause status, uric acid had correlation with BMD. CONCLUSION: In this study, homocysteine had no correlation with BMD. But in natural antioxidant, uric acid had only positive correlation with BMD.

Effects of Menopausal Hormone Therapy on Uterine Myoma in Menopausal Women

OBJECTIVES: The aim of the present study is to evaluate the long term effects of estrogen-progestogen therapy (EPT) on uterine myomas volume in postmenopausal women. METHODS: We performed a retrospective analysis on postmenopausal women with asymptomatic uterine myoma during the period between April, 2008 and September, 2012. Postmenopause was defined as amenorrhea for longer than a year or serum follicle stimulating hormone levels higher than 40 IU/L. The volume of the myoma was assessed by transvaginal ultrasonography for every 6 months after administration of EPT. RESULTS: Thirty-eight women were included in the study, with 32 in the EPT group and 6 in the control group. Overall, uterine myoma volume (mean +/- standard deviation, cm3) in the EPT group was 19.5 +/- 24.6 at baseline, and those at 6 and 12 months were 24.7 +/- 35.1 and 28.5 +/- 56.4, respectively. Myoma volume did not change significantly with EPT, and these changes were not significantly different from the control group. Myoma volume changes were not significantly different in the subgroups according to the route of estrogen administrations and the method of progestogen administrations. Clinically significant volume increases during one year of EPT was noted in 28.1% (9/32), however, only one showed transient increases. CONCLUSION: Our results suggest that treating postmenopausal woman with EPT on a long-term basis does not increase the volume of uterine myomas.

The Relationship between Uterine Myoma Growth and the Endocrine Disruptor in Postmenopausal Women

OBJECTIVES: To investigate the number of leiomyoma patients-exposed to bisphenol A (BPA) and to observe whether the serum concentration of BPA is related to leiomyoma growth. METHODS: A total of 158 patients were recruited for this study. Leiomyoma patients were divided into three groups, mild (n = 48), moderate (n = 32) and severe (n = 28), according to the size of leiomyomas. The control (n = 30) group was defined as having no leiomyomas. Transvaginal ultrasonography was used to identify and measure the leiomyomas. Serum BPA concentrations were measured by enzyme-linked immunosorbent assay. RESULTS: BPA was detected in 87.0% out of a total of 158 samples, and in 86.0% out of 108 leiomyoma patients. In detail, the detection rates of serum BPA were 88.0% in the control group, 77.2% in the mild group, 90.0% in the moderate group and 96.0% in the severe group. The mean BPA concentration in the control group was 0.558 +/- 0.097 ng/mL, the leiomyoma groups, the mean BPA concentrations were 0.274 +/- 0.063 ng/mL (mild), 0.346 +/- 0.064 ng/mL (moderate) and 0.647 +/- 0.039 ng/mL (severe) (P = 0.0003). Values represent the mean +/- standard error. CONCLUSION: The detection rates of serum BPA in the control and leiomyoma groups were 88.0% and 86.0%, respectively. However, there was no significant difference in the serum BPA concentrations between the control and leiomyoma groups. To verify the effect of BPA on leiomyoma growth, a close and sequential monitoring is recommended for people who are at risk for uterine leiomyoma.

A Case of Vaginal Cancer with Uterine Prolapse

Primary vaginal cancer combined with uterine prolapse is very rare. We present a case of 80-year-old postmenopausal women complaints of something coming out per vagina for the past 20 years, along with blood stained discharge, foul odor leukorrhea, and severe pelvic pain for the last 3 months. A 4 x 5 cm ulcer was present on middle third of vaginal wall with marked edema and ulceration of surrounding tissue. The prolapse was reduced under intravenous sedation in operating room. On gynecologic examination, uterus was normal in size, no adnexal mass was examined, and both parametrium were thickened. Papanicolaou smear was normal. Biopsy of the ulcer at vaginal wall revealed invasive squamous cell carcinoma of vagina. Magnetic Resonance Imaging of abdomen and pelvis showed left hydronephrosis and liver metastasis. Positron emission tomography (PET)/computed tomography (CT) revealed metastasis to lung, liver and iliac bone. She died from progression of disease one month after diagnosis.

A Case of Torsion of a Subserosal Leiomyoma

Uterine leiomyoma is one of the most common gynecological tumor, whereas acute torsion of the uterine leiomyoma is very rare. We report a case of subserosal leiomyoma that was first detected by ultrasonography, and further confirmed as torsion of subserosal leiomyoma by laparoscopic surgery.

A Case of Adenoid Basal Carcinoma of the Uterine Cervix

Adenoid basal carcinoma of the uterine cervix is uncommon neoplasia mostly occurring in postmenopausal women. It has excellent prognosis and a favorable clinical course. In addition, adenoid basal carcinoma is differentiated from adenoid cystic carcinoma by histologic and cellular morphologies, and immunohistochemistry. In this paper, we present the case of a 22 year old Korean female. She initially had a high-grade squamous intraepithelial lesion (HSIL) on Pap smear and a subsequent cervical loop electrosurgical excision procedure (LEEP) specimen revealing adenoid basal carcinoma. The lesion showed the histologic characteristics of adenoid basal carcinoma. Because of the lesion's low potential for recurrence and metastasis, the young primipara had a conization procedure performed and has been under close observation.

Expression of CD44 in endometrial stromal cells from women with and without endometriosis and its effect on the adherence to peritoneal mesothelial cells

OBJECTIVE: This study was performed to compare the expression of CD44 in endometrial stromal cells (ESCs) of women with and without endometriosis and to evaluate the role of CD44 in the adherence of ESCs to peritoneal mesothelial cells (PMCs). METHODS: A PMC adherence assay was performed to evaluate the adherence of ESCs to PMCs in women with and without endometriosis. The expression of CD44 mRNA was measured by reverse transcription-polymerase chain reaction. CD44 protein was evaluated by Western blot analysis. RESULTS: There were no significant differences in the expression of CD44 mRNA and protein in ESCs or in the binding of ESCs to PMCs between patients with endometriosis and controls. Although the expression of CD44 protein was decreased in both women with endometriosis and controls after anti-CD44 antibody treatment, there was no effect on binding of ESCs to PMCs. Treatment of ESCs with peritoneal fluid from endometriosis patients resulted in a significant increase in binding of ESCs to PMCs compared to untreated ESCs in the endometriosis group. CONCLUSION: This study demonstrates that the expression of CD44 protein in ESCs from women with endometriosis might not be directly associated with adherence to PMCs.

Mortality Associated with Hormone Replacement Therapy in Postmenopausal Women / 대한폐경학회지

There was controversy about decrease in mortality as the eventual result of hormone replacement therapy (HRT). The reduction of mortality was known in large observational-cohort studies in women with HRT compared with non-HRT after correction of confounding factors. The second analysis of Women's Health Initiative (WHI) results revealed that the 30% decrease in mortality was observed in HRT users. These findings resemble with the results of past observational studies. The meta-analysis including the second analysis of WHI results showed that HRT use in young menopausal women decrease the mortality. Although there was a chaos about the risk and benefit of HRT since the first announcement of WHI study in 2002, HRT in young menopausal women could decrease the morbidity and mortality related to coronary heart disease and stroke.

Effects of simvastatin on the proliferation and apoptosis of human endometrial stromal cells from women with endometriosis / 대한산부인과학회지

OBJECTIVE: To evaluate the effects of simvastatin on the proliferation and apoptosis of human endometrial cells from women with endometriosis. METHODS: Endometrial tissues were obtained from four women with endometriosis. The endometrial stromal cells isolated from tissue were cultured with 0, 2 and 10 micrometer simvastatin treatments for 48 hours. The proliferation of endometrial stromal cells was inhibited with 2 and 10 micrometer simvastatin treatments compared to control. The effect of simvastatin on the sub-G1 phase of cell cycle was determined by flow cytometry. The expression of apoptosis related molecule (Bcl-2, Bax and caspase-3) was examined in control and simvastatin treatments using western blot. RESULTS: The sub-G1 phase was higher in 10 micrometer simvastatin than in control and 2 micrometer simvastatin (P<0.05). This result showed that simvastatin could induce apoptosis of stromal cells. The expression of Bcl-2 was increased in simvastatin treatments slightly (P<0.05) and the expression of Bax was not different between control and experimental groups. The activation of caspase-3 was significantly higher in 10 micrometer simvastatin treated group than control and 2 micrometer simvastatin treated groups (P<0.05). CONCLUSION: Simvastatin induces apoptosis of endometrial stromal cells and inhibits their proliferation. It was considered that simvastatin could potentially be a therapeutic agent for the treatment of endometriosis.

The hyperexpressions of putative stem cells in the eutopic endometrium of patients with advanced endometriosis / 대한산부인과학회지

OBJECTIVE: Recently it has been proposed that stem cells may be associated with the pathogenesis of endometriosis. The purposes of this study are to investigate whether the eutopic endometrial cells of women with or without endometriosis show the characteristics of stem cells in vitro and have a difference of the expressions of the undifferentiated stem cell markers as OCT-4 and CXCR4. METHODS: A total of 6 women with advanced endometriosis and a total of 10 women without endometriosis, adenomyosis or leiomyoma were included in this study. The eutopic endometrial cells, which were obtained from the menstrual blood at menstrual cycle day 2 to 4, were cultured in vitro for approximately 2 weeks, subsequently the putative very small stem cells were separated by Percoll density gradient method and were cultured. The expressions of OCT-4 and CXCR4 were analyzed by real time RT-PCR. RESULTS: The eutopic endometrial cells of the group of endometriosis compared with the control group showed the different morphological characteristics in vitro; more commonly heterogeneous supportive cells, very small round cells less than 3 micrometer and 5~15 micrometer sized hyperchromatic round cells. After the separation of very small round cells by Percoll density gradient method, these cells showed the several characteristics of stem cells; self-renewal, asymmetric cell division, colony formation and embryoid body-like formation. Also These cells showed the similar characteristics of very small embryonic-like stem cells; the mobile cells smaller than erythrocyte, the cell migration or adhesion to supportive cells, the sphere formation by cell aggregation and the formation of new differentiated cell by cell fusion. The expressions of OCT-4 and CXCR4 in the group of endometriosis are respectively 5.66 times and 17.69 times as high as the control group (P<0.05). CONCLUSION: The very small round cells less than 3 micrometer and 5~15 micrometer sized hyperchromatic round cells, which showed the several characteristics of stem cells in vitro, were more common in eutopic endometrial cells of patients with endometriosis and the expressions of OCT-4 and CXCR4 were significantly higher. This study suggests that stem cells might play a key role in the pathogenesis of endometriosis and OCT-4 and CXCR4 might be used as a tool for diagnosis or follow-up.

The infertility treatment related with polycystic ovary syndrome / 대한산부인과학회지

The treatment of infertile women with polycystic ovary syndrome (PCOS) has not yet been established. Before any intervention is initiated, lifestyle modification with diet and exercise leading to weight loss should be emphasized in overweight women. The recommended first-line treatment for ovulation induction remains clomiphene citrate. If clomiphene citrate use fails to result in ovulation or pregnancy, the recommended second-line intervention is exogenous gonadotropins. The use of exogenous gonadotropins is related to an increased risk for multiple pregnancies, and, therefore, intense ovarian response monitoring is required. Laparoscopic ovarian surgery is an alternative to gonadotropin therapy because this surgery is as effective as gonadotropin in pregnancy rate or live birth rate. However, the surgery may require additional ovulation induction drug and should be performed by well-trained surgeon, its use solely to induce ovulation is unwarranted. Recommended third-line treatment is in vitro fertilization (IVF). IVF reduces the risk of multiple pregnancies by using single-embryo transfer in women with PCOS. The use of metformin alone as first-line infertility therapy or in combination with clomiphene is surrounded by controversies. Aromatase inhibitors appear to be as effective as clomiphene citrate for induction of ovulation, but the drug is currently not approved for treatment of infertility. Further studies should demonstrate the efficacy and long term safety.

Relationship between Ghrelin levels of maternal serum, umbilical vein and birth weight / 대한산부인과학회지

OBJECTIVE: Ghrelin is a newly isolated peptide from the stomach. Subsequent studies revealed that ghrelin is expressed in human placenta. Circulating ghrelin levels reflect acute and chronic energy balance in humans. However, it is not proven whether ghrelin plays a role during pregnancy. The purpose of this study was to compare relationship between ghrelin levels of maternal serum, umbilical vein and birth weight. METHODS: We measured maternal ghrelin levels (N=41) in each trimester and postpartum whose fetus were appropriate-for-gestational age. Also we checked cord blood ghrelin levels at delivery in appropriate-for-gestational age group (N=20) and small-for-gestational age group (N=20). RESULTS: Ghrelin was detected in all samples from maternal and cord blood. Maternal serum ghrelin levels showed a peak in the 2nd trimester (35.7+/-12.7 pg/mL) and decreased in the late 3rd trimester (26.5+/-10.3 pg/mL). An increase was observed again in postpartum, which was measured at one day after delivery. There was no significant correlation between maternal serum ghrelin level and birth weight (P>0.05), but there was statistically significant correlation between cord blood ghrelin level and birth weight (r=-0.411, P<0.05). CONCLUSION: Maternal serum ghrelin levels showed a peak around mid-gestation during pregnancy and then, decreased in the 3rd trimester, the time of increased maternal body weight. There was no association between maternal serum ghrelin level and birth weight. But small-for-gestational age neonates present with higher umbilical cord ghrelin level than that of appropriate-for-gestational age neonates. It is conceivable that ghrelin may play a physiologic role in fetal adaptation to intrauterine malnutritional state.

The effects of leptin on in vitro development of mouse embryos / 대한산부인과학회지

OBJECTIVE: To investigate the effects of leptin on in vitro development of mouse embryos. METHODS: Female C57BL mice, aged 8 to 15 weeks, were superovulated with IP injection of 5 IU of PMSG followed by 5 IU hCG at 48 hours later. And then the mice were mated with male mice. The next morning, one-cell embryos were collected and cultured in media added with various concentrations (0, 5, 50, 500 ng/mL) of leptin for 4 days. In addition, to determine whether the sensitivity to leptin varied at different stages of development, embryos at 2- or 4-cell stage were treated with the same concentrations of leptin and cultured up to blastocyst stage. The total cell number of blastocyst was assessed and the expression of leptin receptor was examined in all stages of development by immnuofluorescence. RESULTS: The rate of blastocyst formation from one-cell embryos significantly increased at culture media that leptin was added at 50 ng/mL concentration, whereas decreased at 500 ng/mL concentration compared to the control (P<0.05). The development rate of embryos, from 2-cell stage, was similar to the rate from 1-cell stage. However, the addition of leptin to culture media in 4-cell embryos had no significant effects on embryo development compared to the control. In addition, the dose-dependent stimulatory or inhibitory effect of leptin on embryo development was weakened at 2-cell and 4-cell embryo stages compared one-cell embryo stage. The total cell number of blastocyst also significantly increased at 50 ng/mL of leptin, but decreased at 500 ng/mL. Leptin receptor was expressed in all stages from one-cell embryos to blastocyst. The intensity of Ob-Rb immnuostaining was mainly stronger in one- or two-cell embryos, decreased with advancing development stages, and increased again in blastocyst. CONCLUSION: This study shows that addition of leptin to embryo culture media affects embryo development in a dose-dependent and developmental stage-dependent manner. The effects of leptin seems to be associated with the expression pattern of leptin receptor at different stages of development.
