Menopausal stages and overactive bladder symptoms in middle-aged women: A cross-sectional study.

OBJECTIVE: To examine the prevalence of overactive bladder (OAB) according to menopausal stages in middle-aged women. DESIGN: Cross-sectional study. SETTING: Total Healthcare Center in South Korea. POPULATION: Middle-aged Korean women (n=3469, mean age, 49.5 ± 2.9 years). METHODS: Menopausal stages were defined according to the Stages of Reproductive Aging Workshop +10 criteria, and menopausal symptoms were assessed using the Korean version of Menopause-Specific Quality of Life (MENQOL). Logistic regression models were used to estimate prevalence ratios with 95% confidence intervals for OAB according to menopausal stage and to assess the associations with menopausal symptoms. MAIN OUTCOME MEASURES: OAB symptoms were evaluated using the Overactive Bladder Symptom Score (OABSS). RESULTS: The prevalence of OAB increased with menopausal stage; however, the multivariable-adjusted prevalence ratios for women in menopausal transition and postmenopausal stage were insignificant (ptrend = 0.160) compared to those for premenopausal women. Among individual OAB symptoms, the multivariable-adjusted prevalence ratios for nocturia increased with menopausal stage in a dose-response manner (ptrend = 0.005 for 1 time/day; ptrend < 0.001 for ≥2 times/day). The association between menopausal stages and nocturia occurring ≥2 times/day was evident in women without OAB and with relatively high MENQOL scores, vasomotor symptoms and difficulty sleeping. CONCLUSIONS: The prevalence of OAB, particularly nocturia, increased with menopausal stage, and the association was obvious in women with other menopausal symptoms. This finding underscores the importance of addressing nocturia as a potential menopausal symptom in middle-aged women. Further studies are required to understand the mechanisms linking OAB with menopausal symptoms in middle-aged women.

Metabolically healthy and unhealthy obesity and risk of vasomotor symptoms in premenopausal women: cross-sectional and cohort studies.

OBJECTIVE: To examine the relationship between metabolically healthy and unhealthy obesity phenotypes and risk of vasomotor symptoms (VMS) in premenopausal women. DESIGN: Prospective cohort study. SETTING: Middle-aged women in a cohort based on regular health screening examinations. POPULATION: Premenopausal Korean women aged 42-52 years were recruited and were followed up for a median of 4.2 years. The cross-sectional and cohort studies comprised 4672 women and 2590 women without VMS at baseline, respectively. METHODS: Adiposity measures included body mass index (BMI), waist circumference and percentage body fat. Being metabolically healthy was defined as not having any metabolic syndrome components or a homeostasis model assessment of insulin resistance of 2.5 or more. MAIN OUTCOMES MEASURES: VMS (hot flushes and night sweats) assessed using the questionnaire. RESULTS: All adiposity measures were positively associated with an increased risk of VMS in both cross-sectional and longitudinal studies. The multivariable-adjusted prevalence ratio (95% confidence interval [CI]) for VMS comparing percentage body fat of 35% or more with the reference was 1.47 (95% CI 1.14-1.90) in metabolically healthy women, and the corresponding prevalence ratio was 2.32 (95% CI 1.42-3.78) in metabolically unhealthy women (Pinteraction  = 0.334). The multivariable-adjusted hazard ratio for incident VMS comparing percentage body fat of 35% or more with the reference was 1.34 (95% CI 1.00-1.79) in metabolically healthy women, whereas the corresponding hazard ratio was 3.61 (95% CI 1.81-7.20) in metabolically unhealthy women (Pinteraction  = 0.036). The association between BMI, waist circumference and VMS did not significantly differ by metabolic health status. CONCLUSIONS: Maintaining normal weight and being metabolically healthy may help to prevent VMS in premenopausal women. TWEETABLE ABSTRACT: Avoiding obesity and a metabolically unhealthy status may help reduce vasomotor symptoms in premenopausal women.

Association of Age at Menarche With Left Ventricular Diastolic Dysfunction in Middle-Aged Women.

BACKGROUND: There is sparse research on whether if early menarche is related to left ventricular (LV) diastolic dysfunction. The present study examined this relationship in Korean women.Methods and Results:In a cross-sectional study we analyzed the records of 18,910 Korean women (≥30 years) who underwent echocardiography as part of a comprehensive health examination. Age at menarche was assessed using standardized, self-administered questionnaires. Presence of LV diastolic dysfunction was determined from the echocardiographic findings. Of the 18,910 women, 3,449 had LV diastolic dysfunction. Age at menarche was inversely associated with prevalence of LV diastolic dysfunction. In a multivariable-adjusted model, odds ratios (95% confidence interval) for LV diastolic dysfunction comparing menarche age to menarche at 15-18 years were 1.77 (1.38-2.27) for <12 years, 1.31 (1.11-1.54) for 12 years, 1.26 (1.11-1.43) for 13 years, and 1.03 (0.91-1.15) for 14 years (P for trend <0.001). Adjusting for body mass index or percent fat mass partially reduced these associations. CONCLUSIONS: This large study found an inverse relationship between menarche age and LV diastolic dysfunction. Future prospective studies are needed to investigate potential causal relationships.

Incidence, natural course, and characteristics of postlaparoscopic shoulder pain.

BACKGROUND: To determine the incidence, natural course, and specific characteristics of postlaparoscopic shoulder pain (PLSP). METHODS: The prospective study included 105 patients undergoing laparoscopy for benign gynecologic diseases. The intensity of pain, and the identification of the pain site, was assessed 24- and 48-h after surgery, using a visual analogue scale. The description and intensity of PLSP, its aggravating and relieving factors, and the response to analgesics were assessed over a 1-week period using a self-reported questionnaire. RESULTS: Of 105 patients, 84 (80%) experienced PLSP. PLSP along with wound pain peaked one day after surgery, gradually subsided, and were not reported by the seventh day after surgery. Of the 84 patients experiencing PLSP, 77 (91.7%) had aggravating and relieving factors, which included position change (48.8%) and rest (42.9%), respectively. Analgesics provided significantly less pain relief for PLSP (32.7 ± 32.2%), when compared to relief of wound pain (68.0 ± 16.2%) (P < 0.001). CONCLUSION: PLSP, identified in 80% of our patients, resolved in most patients within the first week after laparoscopy. Since PLSP is less responsive to analgesics, when compared to wound pain, surgeons should pay attention to the prevention of PLSP among patients undergoing laparoscopy.

Randomised comparison of silicone gel and onion extract gel for post-surgical scars.

To compare the efficacy of silicone gel and onion extract gel on new surgical wounds, we performed a randomised controlled trial evaluating the appearance of the laparoscopic surgical scars of 60 subjects after 12 weeks of two times daily application of either silicone gel or onion extract gel. Objective scar assessment by the Vancouver Scar Scale (VSS) and the Image Panel Scale (IPS) and subjective scar assessment by the Body Image Scale (BIS) and Cosmetic Scale (CS) were performed after 12 weeks of treatment. Safety was also evaluated by gathering adverse events related to application of the gel. After 12 weeks of applying the assigned gel, there were no differences between the two groups in VSS (p = .779), IPS (p = .621), BIS (p = .924), or CS (p = .843). Subject compliance and safety with the assigned gel was similar between the two study groups. Our conclusion was that silicone gel and onion extract gel had similar compliance, side effects and efficacy in making surgical scars less distinct. Impact Statement What is already known on this subject: There are commercially available, topical scar emollients for prevention of surgical scarring. Despite their popularity, data demonstrating the efficacy of these scar emollients are lacking. What do the results of this study add: After 12 weeks of applying the assigned topical scar emollients, there were no differences between the two groups in terms of cosmesis and satisfaction. What are the implications of these findings for clinical practice and/or further research: Silicone gel and onion extract gel had similar compliance, side effects and efficacy in making surgical scars less distinct.

Binge eating is associated with trait anxiety in Korean adolescent girls: a cross sectional study.

BACKGROUND: Binge eating occurs more frequently in women than in men, and is known to be related to psychological factors such as stress, depression, and anxiety. This study examined the relationship between binge eating and depression, trait anxiety, and perceived stress in Korean adolescents. METHODS: Four hundred girls (aged 17-18 years) from two high schools located in Seoul completed self-report questionnaires. In total, 327 participants returned reliable responses, and were included in the final study. Binge eating was measured using the Bulimic Inventory Test Edinburgh. The questionnaire also included the Perceived Stress Scale (PSS), Trait Anxiety (TA) of State-Trait Anxiety Inventory, Anxiety Sensitivity Inventory (ASI), and Beck Depression Inventory (BDI). RESULTS: The binge-eating group had higher BMI than the control group. The binge-eating group showed higher scores than control on the PSS, BDI, ASI, and TA. The TA was most highly correlated with binge eating. From logistic regression analysis, TA was revealed to be the only factor that raised the risk of binge eating, whereas PSS, BDI, and ASI showed no statistical significance. CONCLUSION: Although binge eating was correlated with perceived stress, depression, and trait anxiety, when their influences were controlled, only binge eating appeared to be associated with trait anxiety.

The Intensity of Postlaparoscopic Shoulder Pain Is Positively Correlated with the Amount of Residual Pneumoperitoneum.

STUDY OBJECTIVE: Residual carbon dioxide, which is inevitably retained in the abdominal cavity after laparoscopy, plays an important role in inducing postlaparoscopic shoulder pain (PLSP). The aim of this study was to determine the relationship between the volume of a residual pneumoperitoneum and the intensity of PLSP. DESIGN: A prospective cohort study (Canadian Task Force classification II-2). SETTING: A university hospital. PATIENTS: A total of 203 patients undergoing laparoscopy for nonmalignant gynecologic diseases. INTERVENTIONS: Gynecologic laparoscopy. MAIN OUTCOME MEASURES: The volume of the residual pneumoperitoneum was measured by performing chest radiography 24 hours after surgery. The pneumoperitoneum was graded as high volume (defined as ≥the median volume of the pneumoperitoneum) and low volume (defined as

Optimal timing for performing hysterectomy according to different phase of menstrual cycle: Which is best?

The aim of this study was to determine whether the different phases of the menstrual cycle could affect operative bleeding in women undergoing laparoscopic hysterectomy. This was a retrospective comparative study. Based on the adjusted day of menstrual cycle, 212 women who underwent laparoscopic hysterectomy were classified into three groups: the follicular phase (n = 51), luteal phase group (n = 125), and menstruation group (n = 36). The primary outcome measure was the operative bleeding. There was no difference in the baseline characteristics of the patients belonging to the three groups. For the groups, there were no significant differences in operative bleeding (p = .469) and change in haemoglobin (p = .330), including operative time, length of hospital stay and complications. The menstrual cycle did not affect the operative bleeding and other parameters. Therefore, no phase of the menstrual cycle could be considered as an optimal timing for performing laparoscopic hysterectomy with minimal operative bleeding. Impact statement What is already known on this subject: the menstrual cycle results in periodic changes in haemostasis and blood flow in the reproductive organs. What the results of this study add: the menstrual cycle did not affect the operative bleeding and other operative parameters during laparoscopic hysterectomy. What the implications are of these findings for clinical practice and/or further research: no phase of the menstrual cycle could be considered as an optimal timing for performing laparoscopic hysterectomy with minimal operative bleeding.

Age at menarche and non-alcoholic fatty liver disease.

BACKGROUND & AIMS: The goal of this study was to examine the association between age at menarche and non-alcoholic fatty liver disease (NAFLD) in Korean women and to explore whether any observed associations were mediated by adult adiposity. METHODS: A cross-sectional study was performed for 95,183 Korean women, aged 30 or older, who underwent a regular health screening examination between March 2011 and April 2013. Information regarding age at menarche was collected using standardized, self-administered questionnaires. The presence of fatty liver was determined using ultrasonographic findings. Poisson regression models with robust variance were used to evaluate the association between age at menarche and NAFLD. RESULTS: Of the 76,415 women evaluated in this study, 9601 had NAFLD. Age at menarche was inversely associated with the prevalence of NAFLD. In a multivariable-adjusted model, the prevalence ratios (95% CIs) for NAFLD comparing menarche at <12, 12, 14, 15, and 16-18 years to menarche at 13 years were 1.31 (1.18-1.45), 1.05 (0.97-1.13), 0.93 (0.87-0.99), 0.87 (0.82-0.93), and 0.78 (0.73-0.84), respectively (p for trend <0.001). Adjusting for adult BMI or percent fat mass (%) substantially reduced these associations; however, they remained statistically significant. The association between age at menarche and NAFLD was modified by age. CONCLUSIONS: We identified an inverse association between age at menarche and NAFLD in a large sample of middle-aged women. This association was partially mediated by adiposity. The findings of this study suggest that obesity prevention strategies are needed in women who undergo early menarche to reduce the risk of NAFLD.

Quality of life after single-port laparoscopic surgery versus conventional laparoscopic surgery for benign gynecologic disease.

BACKGROUND: The aim of current study was to determine whether single-port laparoscopic surgery (SP-LS) improves the health-related quality of life (QoL) compared with conventional laparoscopic surgery (conventional LS) in women with benign gynecologic disease. METHODS: We performed a prospective case-control study from October 2010 to December 2012. A total of 273 women with benign gynecologic disease participated in this study, and 135 of them were in the SP-LS group and 138 in the conventional LS. We evaluated QoL after SP-LS or conventional LS. All patients were asked to complete short-form 36 (SF-36) QoL health surveys preoperatively and at 1, 3, and 6 months postoperatively. RESULTS: Clinical characteristics and operative outcomes showed no significant differences between both groups. SP-LS had no benefits in QoL compared with conventional LS in the main categories, even though SP-LS showed statistically significant higher scores than conventional LS for the role of physical domain at 1 month postoperatively and for social function at 3 months postoperatively. In contrast to this, conventional LS had statistically significant higher scores than SP-LS for role function, bodily pain, general health, vitality, and emotional well-being at 6 months postoperatively. CONCLUSIONS: With a 6-month follow-up, SP-LS does not offer a QoL benefit over conventional LS in women with benign gynecologic disease. However, a larger prospective randomized study would be required to confirm this.

Effect on ovarian reserve of hemostasis by bipolar coagulation versus suture during laparoendoscopic single-site cystectomy for ovarian endometriomas.

STUDY OBJECTIVE: To compare the postoperative decrease in ovarian reserve between hemostasis by bipolar coagulation and suture during laparoendoscopic single-site cystectomy (LESS-C) for ovarian endometriomas. DESIGN: Prospective comparative study (Canadian Task Force Classification II-1). SETTING: University hospital. PATIENTS: One hundred twenty-five patients with ovarian endometriomas. INTERVENTIONS: Patients with endometrioma were managed by hemostasis with either bipolar coagulation (n = 62) or suturing (n = 63) during LESS-C. We evaluated the impact of surgery on ovarian reserve using serum anti-Müllerian hormone (AMH) levels, which were measured before surgery and 3 months after surgery in all patients. MEASUREMENT AND MAIN RESULTS: Baseline characteristics such as age, bilaterality of endometriomas, and preoperative AMH levels were similar between the 2 study groups. There were also no differences between the 2 groups in surgical outcomes, such as operative time, operative blood loss, or operative complications. In both study groups, postoperative AMH levels were lower than preoperative AMH levels (p < .001). The decline rate of AMH levels was significantly greater in the bipolar coagulation group than in the suture group (42.2% [interquartile range, 16.5%-53.0%] and 24.6% [interquartile range, 11.6%-37.0%], respectively, p = .001). CONCLUSION: Hemostasis by bipolar coagulation after stripping of the endometrioma during LESS-C reduces ovarian reserve more than suturing does, as determined by serial AMH levels. Therefore, suturing may be a better hemostatic choice after stripping ovarian endometriomas.

Timing for a Laparoscopic Myomectomy During the Menstrual Cycle.

OBJECTIVE: To determine whether the different phases (follicular phase, luteal phase, or menstruation) of the menstrual cycle could affect the operative blood loss during a laparoscopic myomectomy. DESIGN: Retrospective comparative study. SETTING: University hospital. PATIENTS: A total of 220 patients who underwent a laparoscopic myomectomy were classified into the follicular phase (n = 90), luteal phase (n = 93), and menstruation group (n = 37) on the basis of the adjusted day of the menstrual cycle. INTERVENTIONS: Laparoscopic myomectomy. MEASUREMENTS AND MAIN RESULTS: The operative blood loss during the laparoscopic myomectomy was measured. The baseline demographics (age, body mass index, and myoma characteristics) were similar among the 3 groups. No significant differences were observed in the operative blood loss (p = .231) and in the hemoglobin change (p = .526) among the 3 groups. In addition, no other statistical differences were found in terms of the other operative results, including the operative time, the length of hospital stay, and operative complications. CONCLUSIONS: The different phase of the menstrual cycle had no effect in the operative blood loss during laparoscopic myomectomy. Therefore, the menstrual cycle is not an important factor to determine the optimal timing of a laparoscopic myomectomy.

A prospective matched case-control study of laparoendoscopic single-site vs conventional laparoscopic myomectomy.

STUDY OBJECTIVE: To compare operative and obstetric outcomes of laparoendoscopic single-site myomectomy (LESS-M) vs conventional laparoscopic myomectomy (LM). DESIGN: Prospective matched case-control study. SETTING: A university hospital and a tertiary care center. PATIENTS: Forty-five women underwent LESS-M, and 90 women underwent conventional LM. INTERVENTION: LESS-M or conventional LM. MEASUREMENTS AND MAIN RESULTS: Operative and obstetric outcomes. There were no significant differences between the 2 groups in demographic characteristics, operative time (135 vs 140 minutes), change in hemoglobin concentration (1.9 vs 1.95 g/dL), return of bowel activity (35 vs 28 hours), hospital stay (5 vs 5 days), or complication rate (11.1% vs 8.9%). Insofar as obstetric outcomes, no significant differences were observed between the 2 groups for duration of follow-up (24.4 vs 23.2 months), pregnancy rate in patients who desired pregnancy (66.7% vs 50.0%), full-term delivery rate (66.7% vs 58.3%), and time to first pregnancy after surgery (7.6 vs 10.1 months). CONCLUSION: LESS-M is feasible and safe and has comparable obstetric outcomes to conventional LM in selected women with symptomatic myomas. However, a large prospective randomized study is needed.

The overtreatment risk of see-and-treat strategy in management of abnormal cervical cytology.

BACKGROUND: To evaluate the feasibility of conization without a prior punch biopsy for patients with abnormal cytology. METHODS: A retrospective review was performed for 700 patients who underwent conization at a single institution from January 2003 to August 2012. Each of these patients was assigned to one of two groups, either the 'see-and-treat' group or the 'three-step' group, depending on whether the patient had undergone a punch biopsy before conization or not. The final histologic results of two groups were compared. RESULTS: The overtreatment risk was higher in the 'see-and-treat' group in patients with atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion (ASCUS/LSIL) cytology (64.7% in the 'see-and-treat' group vs. 36.5% in the 'three-step' group; p = 0.001). There was no significant statistical difference in the rate of cervical dysplasia or invasive carcinoma in patients with high-grade squamous intraepithelial lesion (HSIL) cytology between groups (91.8% in the 'see-and-treat' group vs. 93.5% in the 'three-step' group; p = 0.793). CONCLUSION: The patients with HSIL on cytology can be managed by a 'see-and-treat' strategy with a low risk of overtreatment. On the other hand, the 'three-step' management is more appropriate in patients with ASCUS/LSIL cytology.

Overactive bladder and cognitive impairment in middle-aged women: A cross-sectional study.

BACKGROUND: Overactive bladder (OAB) is a common condition in middle-aged and older women. It has been reported to be potentially linked to cognitive decline, particularly in older adults. This study investigated the association between OAB symptoms and cognitive impairment in middle-aged women. MATERIALS AND METHODS: This cross-sectional study had a sample of 1652 women (mean age 49.3 ± 2.8 years) who were not taking medication for either urinary tract infection or OAB. OAB symptoms and cognitive function were evaluated by self-administered questionnaires: the Overactive Bladder Symptom Score and the Alzheimer's disease 8. Logistic regression models estimated prevalence ratios (PRs) with 95 % confidence intervals (CI) for cognitive impairment according to the presence/absence of OAB. Mediation analyses assessed the impact of poor sleep quality on this association. RESULTS: Cognitive impairment was more prevalent in women with OAB than in those without OAB (multivariable-adjusted PR: 1.88 [95 % CI: 1.52-2.24]). Women experiencing nocturia (≥twice a night), urinary urgency at least once a week, and urgency urinary incontinence at least once a week had multivariable-adjusted PRs (95 % CI) for cognitive impairment of 2.08 (1.50-2.65), 2.12 (1.66-2.58), and 1.75 (1.17-2.34), respectively. Poor sleep quality mediated 10.81 % [95 % CI: 4.55-19.44 %] of the relationship between OAB and cognitive impairment. CONCLUSIONS: Among middle-aged women not taking OAB medications, OAB symptoms were associated with cognitive impairment, partly because of poor sleep quality. Further research is needed to determine whether early screening of patients with OAB can help identify those susceptible to cognitive impairment associated with OAB medication and if preventive measures should be targeted at this group.

Early-onset vasomotor symptoms and development of depressive symptoms among premenopausal women.

BACKGROUND: We investigated the association between vasomotor symptoms (VMSs) and the onset of depressive symptoms among premenopausal women. METHODS: This cross-sectional study included 4376 premenopausal women aged 42-52 years, and the cohort study included 2832 women without clinically relevant depressive symptoms at baseline. VMSs included the symptoms of hot flashes and night sweats. Depressive symptoms were evaluated using the Center for Epidemiological Studies Depression Scale; a score of ≥16 was considered to define clinically relevant depressive symptoms. RESULTS: Premenopausal Women with VMSs at baseline exhibited a higher prevalence of depressive symptoms compared with women without VMSs at baseline (multivariable-adjusted prevalence ratio 1.76, 95 % confidence interval [CI] 1.47-2.11). Among the 2832 women followed up (median, 6.1 years), 406 developed clinically relevant depressive symptoms. Women with versus without VMSs had a significantly higher risk of developing clinically relevant depressive symptoms (multivariable-adjusted hazard ratio, 1.72; 95 % CI 1.39-2.14). VMS severity exhibited a dose-response relationship with depressive symptoms (P for trend <0.05). LIMITATIONS: Self-reported questionnaires were only used to obtain VMSs and depressive symptoms, which could have led to misclassification. We also could not directly measure sex hormone levels. CONCLUSIONS: Even in the premenopausal stage, women who experience hot flashes or night sweats have an increased risk of present and developed clinically relevant depressive symptoms. It is important to conduct mental health screenings and provide appropriate support to middle-aged women who experience early-onset VMSs.

Vasomotor and other menopause symptoms and the prevalence of ideal cardiovascular health metrics among premenopausal stage women.

OBJECTIVE: We examined the association between menopause symptoms and the prevalence of ideal cardiovascular health (CVH) metrics among premenopausal women. METHODS: This cross-sectional study comprised 4,611 premenopausal women aged 42 to 52 years. Data for CVH metrics were collected during health screening examinations. Menopause symptoms were measured using the Korean version of the Menopause-Specific Quality of Life questionnaire. For vasomotor, psychosocial, physical, and sexual symptoms, participants were divided into absent or symptomatic groups, further divided into tertiles (range, 0-7; 7 being the most bothersome). Ideal CVH metrics were defined according to the American Heart Association Life Simple 7 metrics, except dietary component. Cardiovascular health metrics were scored from 0 (unhealthy) to 6 (healthy) and classified as poor (0-2), intermediate (3-4), and ideal (5-6). Multinomial logistic regression models were used to estimate the prevalence ratios for intermediate and poor CVH metrics using ideal CVH as the reference. RESULTS: The overall and 4 menopause-specific quality of life domain scores were significantly associated with poorer CVH metrics scores in a dose-response manner ( P < 0.05). After adjusting for age, parity, education level, anti-Mullerian hormone levels, and alcohol intake, women with the most bothersome degree for vasomotor, psychosocial, physical, and sexual symptoms had significantly higher prevalence of poor CVH metrics, with corresponding prevalence ratios (95% confidence interval) of 2.90 (1.95-4.31), 2.07 (1.36-3.15), 3.01 (1.19-7.65), and 1.66 (1.15-2.39), respectively, compared with those without each vasomotor, psychosocial, physical, and sexual symptom. CONCLUSIONS: Premenopausal stage women with either vasomotor or nonvasomotor menopausal symptoms have significantly higher prevalence of poor CVH metrics, compared with those without any menopausal symptoms.

Differences of the association of anti-Müllerian hormone with clinical or biochemical characteristics between women with and without polycystic ovary syndrome.

The aim of the present study was to compare the associations of anti-Müllerian hormone (AMH) with clinical or biochemical characteristics between women with and without polycystic ovary syndrome (PCOS). We also explored the optimal cutoff point of AMH to diagnose PCOS. A cross-sectional study was performed in 87 women diagnosed with PCOS and 53 healthy control subjects. Body mass index (BMI), indices of insulin resistance, metabolic syndrome-related variables, reproductive hormones and serum AMH were measured in all subjects. We conducted receiver operating characteristic (ROC) curve analysis to determine the cutoff of AMH for diagnosis of PCOS. Serum AMH levels were significantly (p <0.001) higher in women with PCOS after adjustment for age and BMI. AMH levels were not significantly related with obesity, indices of insulin resistance, and metabolic syndrome-related variables in both PCOS and control groups. In the control group, AMH levels showed positive correlations with total testosterone (p <0.001), free testosterone (p=0.024), and adiponectin (p=0.002), and showed negative correlations with age (p=0.010) and estradiol (E2) (p=0.012). However, only total (p=0.044) and free testosterone (p=0.012) levels showed significant positive correlations with serum AMH level in PCOS group. ROC curve analysis showed a cutoff point for AMH of 7.82 ng/mL (sensitivity 75.9%, specificity 86.8%) for diagnosis of PCOS. Differences of the association of AMH with clinical or biochemical characteristics between women with PCOS and control groups were observed. This might contribute to the pathogenesis of PCOS, although further investigation is necessary to elucidate the detailed mechanism.

The gap between physicians and the public in satisfaction with the National Health Insurance system in Korea.

The Korean National Health Insurance (NHI) system was an unprecedented accomplishment that was achieved in a short period of time. In this study, we sought to identify gaps between physicians and the public with respect to attitudes toward the NHI system in Korea. The study population was derived from the 2008 Korean Medical Association Survey, which was conducted to investigate satisfaction with and perceptions of the NHI system among physicians (n = 961) and the public (n = 935). Only 6.5% of the physicians were satisfied with NHI system, and 71.5% were dissatisfied with it. In contrast, 28.3% of the public were satisfied with the NHI system, and 21.4% were dissatisfied. The level of dissatisfaction expressed by physicians (2.03 ± 0.91 on a five-point scale) was also higher than that expressed by the public (3.06 ± 0.84). Despite rapid growth of NHI system, a large gap in satisfaction exists between physicians and the public.

High low-density lipoprotein cholesterol level is associated with an increased risk of incident early-onset vasomotor symptoms.

We investigated the associations between serum lipid profiles and risk of early-onset vasomotor symptoms (VMSs) in premenopausal women. This cohort study comprised 2,540 premenopausal women aged 42-52 years without VMSs at baseline (median follow-up: 4.4 years). VMSs, including hot flashes and night sweats, were assessed using the Menopause-Specific Quality of Life questionnaire (Korean version). Early-onset VMSs were defined as VMSs that occurred premenopause; moderate/severe VMSs were defined as a score of ≥ 3 points (range: 0 to 6, 6 being most bothersome). Cox proportional hazard regression models were used to estimate hazard ratios with 95% confidence intervals (CI) for the development of VMSs across the lipid levels. Higher low-density lipoprotein (LDL) cholesterol levels were positively associated with increased risk of early-onset VMSs. Compared to the < 100 mg/dL LDL group, the multivariable-adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) for incident VMSs were 1.19 (1.03-1.37) and 1.20 (1.03-1.40) in participants with LDL cholesterol levels of 100-129 mg/dL and ≥ 130 mg/dL, respectively (P for trend = 0.027). The multivariable-adjusted HR for incident moderate/severe VMSs was 1.37 (95% CI: 1.08-1.73) in participants with LDL ≥ 130 mg/dL, compared to those with LDL < 100 mg/dL. Meanwhile, triglycerides and total and high-density lipoprotein cholesterol levels were not significantly associated with early-onset VMSs risk in premenopausal women. Premenopausal women with high serum LDL cholesterol concentrations had a higher risk of incident early-onset VMSs. Further studies should confirm our findings and examine whether LDL-lowering interventions reduce the risk of early-onset VMSs among women during menopause transition.
