RESUMEN

OBJECTIVE: We aimed to determine whether ovarian-preserving surgery for adnexal torsion helps preserve ovarian function without increasing the risk of postoperative complications. METHODS: We retrospectively evaluated 71 women who were surgically diagnosed with adnexal torsion between January 2015 and December 2019 at Severance Hospital, Yonsei University College of Medicine (ovarian preservation group, 56; oophorectomy, 15). Serum anti-Müllerian hormone (AMH) levels measured within 6 months before surgery were compared to levels measured 6-24 months after surgery. Surgical findings and postoperative complications were compared between the groups. RESULTS: There was a borderline significant difference in the decrease in serum AMH levels between the oophorectomy group and ovarian preservation group before and after surgery. There were no significant differences between the groups in terms of fever, infection, or duration of admission. Discoloration of the twisted ovary was found in 27.3% and 33.3% of the patients in the ovarian preservation and oophorectomy groups, respectively. There was no difference in the decrease in serum AMH levels between patients with and those without discoloration. CONCLUSION: Ovarian-preserving surgery may not increase postoperative complications in patients with adnexal torsion, even if a twisted mass is suspected to be necrotic. Moreover, the ovarian reserve may not be affected by torsion if the ovary is preserved. Conservative ovarian surgery can be safely performed to preserve the reproductive potential of women with adnexal torsion and cystic masses.

RESUMEN

The regeneration potential of implantable organ model hydrogels is applied to treat a loss of ovarian endocrine function in women experiencing menopause and/or cancer therapy. A rat ovariectomy model is used to harvest autologous ovary cells while subsequently producing a layer-by-layer form of follicle spheroids. Implantation of a microchannel network hydrogel with cell spheroids [vascularized hydrogel with ovarian spheroids (VHOS)] into an ischemic hindlimb of ovariectomized rats significantly aids the recovery of endocrine function with hormone release, leading to full endometrium regeneration. The VHOS implantation effectively suppresses the side effects observed with synthetic hormone treatment (i.e., tissue overgrowth, hyperplasia, cancer progression, deep vein thrombosis) to the normal levels, while effectively preventing the representative aftereffects of menopause (i.e., gaining fatty weight, inducing osteoporosis). These results highlight the unprecedented therapeutic potential of an implantable VHOS against menopause and suggest that it may be used as an alternative approach to standard hormone therapy.

RESUMEN

OBJECTIVE: To evaluate the effect of female sex hormones on the clinical outcomes of coronavirus disease 2019 patients using national claims data. METHODS: This retrospective cohort study used the Health Insurance Review and Assessment data of 5,061 adult patients with laboratory-confirmed coronavirus disease 2019 in South Korea from January 20 to April 8, 2020. To evaluate the effect of hormone therapy on clinical outcomes among women, subgroup analyses using age-matched case-control data were performed. RESULTS: Coronavirus disease 2019 was most prevalent in women in the 20-39 years age group (1,250 [44.14%]). Men were more likely to receive oxygen therapy (144 [6.46%] vs 131 [4.63%], P = 0.004), be admitted to the intensive care unit (60 [2.69%] vs 53 [1.87%], P = 0.049), and have a longer length of stay after admission to the intensive care unit (19.70 ± 11.80 vs 14.75 ±â€Š9.23, P = 0.016). However, there was no significant difference in the mortality rate (men vs women: 42 [1.88%] vs 42 [1.48%], P = 0.267). In the multivariable Cox analysis, older age and underlying comorbidities, but not sex, were independent risk factors for mortality. Hormone therapy was not significantly associated with clinical outcomes. CONCLUSIONS: This study, using nationwide data, suggests that female sex hormones are not associated with the morbidity and clinical outcomes of coronavirus disease 2019 in South Korea.

RESUMEN

BACKGROUND: Despite the good prognosis in patients with transplant organs, limited evidence is available on how immunosuppressants affect pregnancy. The aim of this study was to determine whether immunosuppressant use affects the pregnancy outcome and to identify whether there is any need to change the immunosuppressant before the patient tries to conceive. METHODS: This retrospective cohort study included women with previous kidney transplantation history who visited the Department of Obstetrics and Gynecology for either infertility or antenatal care between January 2005 and May 2016. A total of 40 cases (36 women) met the inclusion criteria. Statistical analyses were performed using SAS version 9.4. RESULTS: There were no differences in the immunosuppressant regimen between the pregnant and non-pregnant groups (never-pregnant+miscarriage) (P = 0.73). Individual immunosuppressant use was significantly different in terms of pregnancy outcome among the never-pregnant, miscarriage, and clinical pregnancy groups (azathioprine, P = 0.01; deflazacort, P < 0.0001). Only deflazacort use differed significantly between the clinical pregnancy and non-pregnant groups (P = 0.003). After adjusting for factors that may affect pregnancy outcome, deflazacort use remained significantly associated with a decreased odds ratio for clinical pregnancy (P = 0.02). Cox regression analysis also showed that deflazacort use was the only remaining factor that could hinder the success of clinical pregnancy (P = 0.03). CONCLUSIONS: Our study suggests that the type of immunosuppressive regimen may not affect the success of clinical pregnancy. However, deflazacort may decrease the possibility of clinical pregnancy in women with kidney transplant when they try to conceive.

RESUMEN

OBJECTIVES: Decreased renal function is associated with increased cardiovascular risk. Our study was planned to verify the association of decreased renal function and subclinical coronary atherosclerosis in postmenopausal women. METHODS: We performed a retrospective review of 251 Korean postmenopausal women who visited the health promotion center for a routine health checkup. Estimated glomerular filtration rate (eGFR) was used to show renal function, which was estimated by calculated using the Cockcroft-Gault (CG) and the modification of diet in renal disease (MDRD) formulas. Coronary atherosclerosis was assessed by 64-row multidetector computed tomography. RESULTS: Women with reduced eGFR (< 60 mL/minute/1.73 m2) had significantly higher brachial-ankle pulse wave velocity (baPWV) than women with normal eGFR (≥ 60 mL/minute/1.73 m2). The eGFR was negatively correlated with baPWV (r = -0.352, P < 0.001), significantly. The eGFR was lower in women with coronary atherosclerosis than in normal control women, markedly. Reduced eGFR was significantly associated with the presence of coronary atherosclerosis (odds ratio [OR] = 7.528, 95% confidence interval [CI] = 2.728-20.772, P < 0.001). CONCLUSIONS: Decreased eGFR was closely associated with increased arterial stiffness and coronary atherosclerosis in postmenopausal women. Evaluating subclinical atherosclerosis by screening the renal function in postmenopausal women may be helpful screening high risk group and considering starting menopausal hormone therapy before atherosclerosis development.

RESUMEN

This study aimed to investigate the association between serum levels of 25-hydroxyvitamin D [25(OH)D] and metabolic syndrome along with its associated risk factors in Korean postmenopausal women. This study was performed using data from the KNHANES 2008-2010 study and included 4,364 postmenopausal Korean women. Clinical and other objective characteristics, seasonality, and presence of metabolic syndrome with its five components were evaluated and correlated with the serum levels of 25(OH)D. Although no statistically significant associations were observed between the levels of serum 25(OH)D and the prevalence of metabolic syndrome, the adjusted OR for elevated blood pressure, elevated triglycerides (TGs), and reduced high-density lipoprotein cholesterol (HDL-C) showed tendency to decrease sequentially as tertiles of serum 25(OH)D levels increased (p for trends  = 0.066, 0.043, and 0.010, respectively). Women in the highest tertile of serum 25(OH)D showed a significant decrease in the prevalence of elevated blood pressure, elevated TGs, and reduced HDL-C as compared with those in the lowest tertile of serum 25(OH)D (p = 0.020, 0.014, and 0.002, respectively). Based on these results, we consider that adequate serum levels of 25(OH)D in Korean postmenopausal women may not entirely indicate a lower risk of developing metabolic syndrome. However, adequate serum levels of 25(OH)D are significantly associated with a decrease in elevated blood pressure, elevated TGs, and reduced HDL-C levels in postmenopausal women.

RESUMEN

OBJECTIVE: To investigate the complete metabolic and phenotypic profiles of a large cohort of untreated, consecutively recruited Korean women with polycystic ovary syndrome (PCOS), for whom a registry for Korean women with PCOS was constructed. DESIGN: Observational study. SETTING: Three infertility clinics and 10 university hospitals. PATIENT(S): Eight hundred sixty-five women with PCOS were recruited using the Rotterdam criteria. INTERVENTION(S): Standardized evaluation protocol and web-based case report form. MAIN OUTCOME MEASURE(S): Metabolic and phenotypic profiles. RESULT(S): The subjects with PCOS mainly consisted of young and nonobese women. The most problematic subjective symptom was menstrual disturbance or infertility, and, on average, the patients seemed to menstruate every 2 months. PCO morphology was observed in 96.5% of the patients. Although few women visited hospitals owing to HA symptoms alone, hirsutism was observed in one-third of the patients (33.9%) and half (47.4%) of the patients had biochemical HA. About one-fifth (20.1%) of the patients had generalized obesity, and one-third (33.2%) had central obesity. Prevalence of dyslipidemia, diabetes, hypertension, and metabolic syndrome were 35.7%, 3.5%, 4.0%, and 13.7%, respectively. Prevalence of prediabetes was 20.8%, and a substantial proportion of additional subjects with normal fasting plasma glucose or oral glucose tolerance tests were identified as having prediabetes by hemoglobin A1C testing. CONCLUSION(S): Our well-defined cohort provided comprehensive estimates of the features of metabolic and phenotypic profiles related to PCOS in Korean women. Further longitudinal follow-up studies are needed to investigate the changes in phenotypic and metabolic markers in this PCOS cohort.

RESUMEN

PROBLEM: The aim of this study was to evaluate serum and urinary levels of vascular endothelial growth factors, tumor necrosis factor-alpha (TNF-alpha), and soluble fms-like tyrosine kinase (sFlt-1) in patients with endometriosis. METHOD OF STUDY: During surgery for pelvic pain, pelvic mass or infertility, serum and urine were collected. Of 70 patients, 46 had histology-proven endometriosis and 24 patients without endometriosis participated as controls. RESULTS: Serum TNF-alpha levels and urinary sFlt-1 levels corrected for creatinine excretion were significantly increased in the endometriosis group (P=0.001 and P=0.011 respectively). Serum sFlt-1 levels and urinary sFlt-1 levels corrected for creatinine were significantly higher in patients with minimal-to-mild disease (P=0.014 and P=0.015 respectively), where serum TNF-alpha levels were increased in moderate-to-severe endometriosis (P<0.001). CONCLUSION: The pathogenesis of minimal-to-mild endometriosis and moderate-to-severe endometriosis seems to be different. Increased sFlt-1 levels in serum and urine of minimal-to-mild disease indicate that sFlt-1 may have an important role in inhibiting angiogenic process of the disease.

RESUMEN

PURPOSE: This study was conducted to investigate the efficacy of black cohosh (Cimicifuga racemosa) and St. John's wort (Hypericum perforatum) in women with climacteric symptoms, and to assess their effects on vaginal atrophy, hormone levels, and lipid profiles. MATERIALS AND METHODS: In this double-blind randomized, placebo-controlled, multicenter study, 89 peri- or postmenopausal women experiencing climacteric symptoms were treated with St. John's wort and black cohosh extract (Gynoplus), Jin-Yang Pharm., Seoul, Korea) or a matched placebo for 12 weeks. Climacteric complaints were evaluated by the Kupperman Index (KI) initially and at 4 and 12 weeks following treatment. Vaginal maturation indices, serum estradiol, FSH, LH, total cholesterol, HDL- cholesterol, LDL-cholesterol, and triglyceride levels were measured before and after treatment. From the initial 89 participants, 77 completed the trial (42 in the Gynoplus group, 35 in the placebo group). RESULTS: Baseline characteristics were not significantly different between the two groups. Mean KI scores and hot flushes after 4 and 12 weeks were significantly lower in the Gynoplus group. Differences in superficial cell proportion were not statistically significant. HDL levels decreased in the control group from 60.20 +/- 16.37 to 56.63 +/- 12.67, and increased in the Gynoplus group from 58.32 +/- 11.64 to 59.74 +/- 10.54; this was statistically significant (p=0.04). CONCLUSION: Black cohosh and St. John's wort combination was found to be effective in alleviating climacteric symptoms and might provide benefits to lipid metabolism.

RESUMEN

Our aim was to demonstrate the potential of first-trimester embryofetoscopy for prenatal diagnosis in a continuing pregnancy. A patient at risk for giving birth to an infant with short rib-polydactyly syndrome, type II (Majewski), presented for prenatal diagnosis at 9 weeks of gestation. A 1 mm semirigid fiberoptic endoscope with an 18 gauge examination sheath and a single-chip digital camera were used for transabdominal embryofetoscopy. Transabdominal embryofetoscopy was performed at 13 weeks of gestation. Direct visualization of the fetus was achieved and no gross limb or facial abnormalities were seen. This case shows that embryofetoscopy is a useful tool for early diagnosis in high-risk patients in the first trimester for continuing pregnancies.
