Is There a Difference in Hirsutism Score in Adolescents with Polycystic Ovary Syndrome on the Basis of Ethnicity and Race?

BACKGROUND: The complex correlation between ethnicity and race, clinical hyperandrogenism as signified by hirsutism, and biochemical androgen concentrations in polycystic ovary syndrome (PCOS) is poorly understood. STUDY OBJECTIVE: The aim of this study was to define the correlation between ethnicity/race and hirsutism score in patients with PCOS. METHODS: We conducted a retrospective chart review of a total of 251 patients with PCOS at the time of diagnosis. Patients were categorized by their ethnicity and race into 5 main groups: Asian (n = 19, 7.6%), Black or African American (n = 11, 4.4%), Hispanic or Latino (n = 26, 10.3%), White (n = 177, 70.5), and others (n = 18, 7.2%). A general linear model was applied using BlueSky software. RESULTS: For the entire study population, the mean age at diagnosis was 15.6 ± 1.7, the mean body mass index (BMI) was 30.6 ± 9.8, the mean hirsutism score using the modified Ferriman-Gallwey score chart was 6.2 ± 3.8, and the mean total testosterone was 40.1 ± 20. The hirsutism score was the highest in the Asian population (mean = 9.1, P = .002) and Hispanic or Latino population (mean = 7.8, P = .02), followed by others (mean = 7.4, P = .04) and the Black or African American population (mean = 7.1, P = .2), compared with the White population (mean = 5.4). This correlation remained significant despite accounting for BMI and androgen levels (P < .001). CONCLUSION: There are factors likely related to hair follicle sensitivity or endogenous response to circulating free androgens that differ between ethnicities and races, such that similar biochemical concentrations lead to differing severity of hirsutism, despite accounting for differences in BMI and androgen levels. More research is needed in this realm to understand the pathophysiologic basis of this interaction.

Racial and ethnic disparities in polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder that impacts women worldwide. There are several racial and ethnic differences in PCOS phenotypes and in PCOS- associated metabolic dysfunction. In this review, we summarize the current literature on disparities in the diagnosis and outcomes associated with PCOS in the United States. Future studies are needed to address gaps in knowledge for racial and ethnic-specific differences in PCOS, and include a large number of non-White and/or Hispanic participants in PCOS studies.

Ethnic discordance in serum anti-Müllerian hormone in European and Indian healthy women and Indian infertile women.

RESEARCH QUESTION: Does anti-Müllerian hormone (AMH) differ between healthy European and Indian women, and are potential ethnic differences modified by infertility diagnosis? DESIGN: Cross-sectional analysis of three prospectively recruited cohorts (n = 2758); healthy European women (n = 758), healthy community cohort from Kolhapur, India (n = 400) and infertility cohort from Kolhapur, India (n = 1600). AMH was determined by assay. Ethnicity, age and cause of infertility were modelled using additive quantile regression models. RESULTS: Healthy Indian women had lower AMH than their healthy European counterparts (population estimates 20.0% lower [95% CI 7.2-36.5]), with increasing discordance with increasing age; at 25 years AMH was 11.9% lower (95% CI 9.4-14.1), increasing to 40.0% lower (95% CI 0-64.6) by age 45. Comparison of healthy and infertile Indian women revealed differences that were related to cause of infertility. Women whose male partner had severe oligoasthenoteratozoospermia (n = 95) had similar AMH to controls; women with polycystic ovary syndrome (n = 220) had higher AMH, especially in those <30 years, and in women with a principal diagnosis of unexplained infertility (n = 757) AMH was lower (median difference 22.6% lower; 95% CI 9.1-37.7) than controls. CONCLUSIONS: AMH is substantially lower in healthy Indian women at all ages than their European counterparts. Infertile Indian women have variable differences in AMH from healthy Indian controls, with the extent and direction of differences primarily reflecting the underlying cause of infertility. Recognition of ethnic and cause-specific differences are critical to ensure accurate contextualizing of results and clinical outcomes for patients.

Association of three missense mutations in the homocysteine-related MTHFR and MTRR gene with risk of polycystic ovary syndrome in Southern Chinese women.

BACKGROUND: The etiology between homocysteine and polycystic ovary syndrome (PCOS) is unclear. In humans, the level of homocysteine is mainly affected by two enzymes: methylene tetrahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR). While the activity of these two enzymes is mainly affected by three missense mutations, namely C677T (MTHFR), A1298C (MTHFR), and A66G (MTRR). This study aims to examine the association between the three missense mutations and PCOS and investigate whether the three missense mutations exerted their effect on PCOS by affecting the homocysteine level. METHODS: A case-control study was designed, comprising 150 people with PCOS and 300 controls. Logistic regression analysis was used to assess the association between the three missense mutations and PCOS. Linear regression analysis was used to assess the association between the three missense mutations and the homocysteine level. Mediation analysis was used to investigate whether the three missense mutations exerted their effect on PCOS by affecting the homocysteine level. RESULTS: Following adjustments and multiple rounds of testing, MTHFR A1298C was found to be significantly associated with PCOS in a dose-dependent manner (compared to AA, OR = 2.142 for AC & OR = 3.755 for CC; P < 0.001). MTRR A66G was nominally associated with PCOS. Mutations in MTHFR A1298C and MTRR A66G were significantly associated with the homocysteine level. Mediation analysis suggested the effect of MTHFR A1298C on PCOS was mediated by homocysteine. CONCLUSIONS: MTHFR A1298C and MTRR A66G were associated with PCOS, and MTHFR A1298C might affect the risk of PCOS by influencing the homocysteine level.

Influence of ethnicity on different aspects of polycystic ovary syndrome: a systematic review.

This systematic review aimed to assess variations in the clinical presentation and treatment outcomes of patients with polycystic ovary syndrome (PCOS) belonging to different ethnicities. A search was performed for studies comparing various clinical aspects of PCOS in two or more different ethnic groups. After screening 2264 studies, 35 articles were included in the final analysis. In comparison with White women with PCOS (wPCOS), East Asian women with PCOS (eaPCOS) were less hirsute, whereas Hispanic women with PCOS (hPCOS), South Asian women with PCOS (saPCOS) and Middle Eastern women with PCOS (mePCOS) were more hirsute. saPCOS had higher androgen and lower sex hormone-binding globulin (SHBG) concentrations, mePCOS had higher DHEAS concentrations, and hPCOS and Black women with PCOS (bPCOS) had lower SHBG and DHEAS measures than wPCOS. Menstrual disturbances were more frequent in eaPCOS. Both saPCOS and eaPCOS had lower body mass index with increased central adiposity. hPCOS and bPCOS were more obese. saPCOS, mePCOS, hPCOS and bPCOS had a higher prevalence of insulin resistance than wPCOS. bPCOS had a better lipid profile but higher blood pressure and cardiovascular risk. Indigenous Australian women with PCOS were more obese and more insulin resistant with higher androgen concentrations. The clinical phenotype of PCOS therefore shows a wide variation depending on ethnicity.

Characterizing the Clinical and Genetic Spectrum of Polycystic Ovary Syndrome in Electronic Health Records.

CONTEXT: Polycystic ovary syndrome (PCOS) is one of the leading causes of infertility, yet current diagnostic criteria are ineffective at identifying patients whose symptoms reside outside strict diagnostic criteria. As a result, PCOS is underdiagnosed and its etiology is poorly understood. OBJECTIVE: We aim to characterize the phenotypic spectrum of PCOS clinical features within and across racial and ethnic groups. METHODS: We developed a strictly defined PCOS algorithm (PCOSkeyword-strict) using the International Classification of Diseases, ninth and tenth revisions and keywords mined from clinical notes in electronic health records (EHRs) data. We then systematically relaxed the inclusion criteria to evaluate the change in epidemiological and genetic associations resulting in 3 subsequent algorithms (PCOScoded-broad, PCOScoded-strict, and PCOSkeyword-broad). We evaluated the performance of each phenotyping approach and characterized prominent clinical features observed in racially and ethnically diverse PCOS patients. RESULTS: The best performance came from the PCOScoded-strict algorithm, with a positive predictive value of 98%. Individuals classified as cases by this algorithm had significantly higher body mass index (BMI), insulin levels, free testosterone values, and genetic risk scores for PCOS, compared to controls. Median BMI was higher in African American females with PCOS compared to White and Hispanic females with PCOS. CONCLUSIONS: PCOS symptoms are observed across a severity spectrum that parallels the continuous genetic liability to PCOS in the general population. Racial and ethnic group differences exist in PCOS symptomology and metabolic health across different phenotyping strategies.

Metabolic comparison of polycystic ovarian syndrome and control women in Middle Eastern and UK Caucasian populations.

To determine if metabolic characteristics differed in women with and without polycystic ovary syndrome (PCOS) between a Caucasian and Middle East population. Comparative cross-sectional analysis. Demographic and metabolic data from Middle Eastern women from Qatar Biobank (97 with PCOS, 622 controls) were compared to a Caucasian PCOS biobank in Hull UK (108 with PCOS, 69 controls). In both populations, PCOS women showed a worse cardiovascular risk profile of increased systolic and diastolic blood pressure, increased C-reactive protein (CRP), reduced HDL, insulin resistance as well as increased androgens compared to their respective controls without PCOS. UK women without PCOS had higher systolic and diastolic blood pressures, and increased testosterone results (p < 0.01) compared to Middle Eastern women without PCOS who had higher inflammatory markers (WBC and CRP), HDL and insulin resistance (p < 0.001). UK PCOS women had a higher body mass index, systolic and diastolic blood pressures, triglycerides (p < 0.01), whilst Middle Eastern PCOS women showed increased testosterone, free androgen index, HDL and CRP (P < 0.01). There was no difference in insulin or insulin resistance between the two PCOS cohorts. This study highlights ethnic population differences because, whilst cardiovascular risk indices were increased for both PCOS cohorts, this may be for different reasons: BMI, waist and hip measurements, systolic and diastolic blood pressure, and triglycerides were higher in the UK cohort whilst testosterone, HDL and CRP were higher in the Middle East population. Insulin resistance did not differ between the two PCOS populations despite differences in BMI.

Association of non-alcoholic fatty liver disease and polycystic ovarian syndrome.

BACKGROUND: Polycystic ovarian syndrome (PCOS) is a common endocrine disorder in women. Women with PCOS have androgen excess as a defining feature. They also have increased insulin resistance and obesity, which are also risk factors for non-alcoholic fatty liver disease (NAFLD). However, published data regarding PCOS as independent risk factor for NAFLD remain controversial. Therefore, we conducted this study to evaluate the association between PCOS and NAFLD using a large national database. METHODS: We identified adult female patients (≥18 years) with PCOS using the National Inpatient Sample database between 2002 and 2014. The control group included patients who did not have a diagnosis of PCOS. Multivariate logistic regression analysis was performed to study the association of NAFLD with PCOS. RESULTS: Out of a total of 50 785 354 women, 77 415 (0.15%) had PCOS. These patients were younger (32.7 vs 54.8; p<0.001) and more likely to be obese (29.4% vs 8.6%; p<0.001) compared with non-PCOS patients. However, the PCOS group had less hypertension (23.2% vs 39.8%), dyslipidaemia (12% vs 17.8%) and diabetes mellitus (18.1% vs 18.3%) (p<0.001 for all). Using multivariate logistic regression, patients with PCOS had significantly higher rate of NAFLD (OR 4.30, 95% CI 4.11 to 4.50, p<0.001). CONCLUSION: Our study showed that patients with PCOS have four times higher risk of developing NAFLD compared with women without PCOS. Further studies are needed to assess if specific PCOS treatments can affect NAFLD progression.

Características fenotípicas y factores de riesgo de síndrome de ovario poliquístico en estudiantes enfermeras / Phenotype characteristics and risk factors of polycystic ovarian syndrome among nursing students

Background: Polycystic ovarian syndrome (PCOS) is a common endocrine condition that occurs in women and is associated with problems such as menstrual irregularities; hirsutism; obesity; insulin resistance; acne; and later life with diabetes mellitus and uterine cancer. The study aim was to assess phenotype characteristics and risk factors of polycystic ovarian syndrome among nursing students. Cross sectional study (descriptive) included a sample of 400 females from Faculty of Nursing, Zagazig University, Egypt.Tools were used for data collection; structured-interviewing questionnaire sheet, data related to anthropometric measures, risk factors about PCOS and observational check list about phenotype characteristics of PCO. The results showed that, (6%) of the studied student females had family history of PCO, nearly half of them had fast food, more than half of studied student females had hirsutism, more than one quarter had acne, (14.5%) had menstrual irregularity and one third of them had continuous abnormal weight gain. Also, this study showed that lack of awareness were found among majority of girls about PCOS. Therefore, it could be concluded that, family history of PCOS, obesity and fast food diet habits are found to be the predisposing factors for development of PCOS. The risk of PCOS increases with presence of one or more identified predisposing factors. Most of the factors tested as predisposing factors in our study are interlinked to each other and are mostly modifiable Although that PCOS is prevalent endocrine disorder, there was poor knowledge among student females in Faculty of Nursing Zagazig University. The study recommended screening program from ministry of health for early detection of predisposing factors of PCOS including the secondary school students and faculties students through educational programs and messages through the counseling, brochures, to increase student's awareness about PCOS symptoms. Further research on larger sample size to identify how the problem is risky and how to deal it. Including the problem in social media and healthy channels. K

Association of vascular endothelial growth factor polymorphisms with polycystic ovarian syndrome risk: a meta-analysis.

BACKGROUND: Polycystic ovarian syndrome (PCOS) is a multi-gene hereditary disorder caused by the interaction of certain gene variation with environmental factors. Previous studies have shown that vascular endothelial growth factor (VEGF) gene polymorphisms are associated with the risk of polycystic ovarian syndrome. However, the results of these studies remain controversial. We performed the present meta-analysis aiming to further investigate the potential relationship between VEGF polymorphisms and susceptibility to PCOS. METHODS: The following databases were systematically searched: PubMed, EMBASE, Web of Science (WOS), China National Knowledge Infrastructure (CNKI), and Wanfang Databases. The correlation between VEGF polymorphisms and PCOS risk was assessed by calculating pooled odds ratios (ORs) and their 95% confidence intervals (95% CIs). Subgroup analyses stratified by ethnicity and source of control were also conducted. Besides, trial sequential analysis (TSA) was done to verify the reliability of the pooled results. RESULTS: 10 relevant case-control studies were incorporated in this meta-analysis, involving 1347 PCOS cases and 1378 controls. The VEGF rs2010963 polymorphism was associated with decreased PCOS risk in the whole population and the Asian populations. The VEGF rs3025039 polymorphism was associated with decreased PCOS susceptibility and the Asian populations, but increased risk of PCOS was observed among the Caucasian populations. In addition, the results of trial sequential analysis (TSA) showed the negative correlation between rs2010963 and PCOS risk, obtained by our meta-analysis, was stable and reliable. CONCLUSION: Overall, different VEGF gene polymorphisms may exert different effects on PCOS susceptibility. The VEGF rs2010963 polymorphism decreases PCOS susceptibility in both the whole population and the Asian populations, and VEGF rs3025039 polymorphism causes lower PCOS susceptibility in the whole population and the Asian populations but higher in the Caucasian populations.

Association of Paraoxonase 1 Gene Polymorphisms and Polycystic Ovarian Syndrome Susceptibility: A Systematic Review and Meta-Analysis.

INTRODUCTION: The goal of this study was to review relevant case-control trials in order to determine the association of paraoxonase 1 (PON1) gene polymorphisms (-108C/T, 55L/M, 192Q/R) and polycystic ovarian syndrome (PCOS) susceptibility. METHODS: Using appropriate keywords, we identified relevant studies using PubMed, Cochrane, Embase, CNKI, VANFUN, and VIP. Key pertinent sources in the literature were also reviewed, and all articles published through April 2019 were considered for inclusion. Based on the qualified studies, we performed a meta-analysis of associations between -108C/T, 55L/M and 192Q/R polymorphisms in PON1 and risk of PCOS. RESULTS: We included 13 case-control studies with 3,660 total patients in the PCOS group and 2,835 in the control group. These studies found that the population with -108C/T locus T were associated with lower PCOS susceptibility by heterozygote model (OR 0.442, 95% CI 0.259-0.754); the Caucasian population with -108C/T locus T were associated with higher PCOS susceptibility by regressive model (OR 2.087, 95% CI 1.242-3.504). The population with 55L/M locus M were associated with higher PCOS susceptibility by regressive model (OR 1.518, 95% CI 1.067-2.160); the Asian population with 55L/M locus M were associated with lower PCOS susceptibility by dominant model and heterozygote model. The population with 192Q/R locus R were associated with higher PCOS susceptibility by the 5 gene models. The Asian population with 192Q/R locus R were associated with higher PCOS susceptibility: allelic model (OR 1.271, 95% CI 1.139-1.417); homozygote model (OR 1.575, 95% CI 1.244-1.995); dominant model (OR 1.299, 95% CI 1.069-1.580); regressive model (OR 1.421, 95% CI 1.207-1.673). The Caucasian population with 192Q/R locus R were associated with higher PCOS susceptibility: heterozygote model (OR 2.113, 95% CI 1.266-3.526). CONCLUSION: Our meta-analysis suggested that 192Q/R locus R were associated with higher PCOS susceptibility in both the Asian and Caucasian population.

Variation analysis of Ghrelin gene in Chinese patients with obesity, having polycystic ovarian syndrome.

Association of single-nucleotide polymorphisms (SNPs) of the ghrelin gene with polycystic ovary syndrome (PCOS)is unclear. However, their correlation with PCOS-related obesity has been observed. The objective of this study was to evaluate the effects of ghrelin gene SNPs on PCOS-related obesity in Chinese women. The full-length sequence of the ghrelin gene was determined to explore the relationship of the SNPs with PCOS-related obesity in Chinese women. The gene was sequenced, including all exons, introns and exon-intron boundaries in 230 Han Chinese women with PCOS and 162 normal women. Significant genotypic and allelic differences were observed between the obese PCOS group and obese control group at rs35681 locus (p = .013 and .017). The genotypic analysis of obese and non-obese people in the PCOS group showed that the proportion of A allele in the obese PCOS group (10.9%) was higher than that of the G allele (3.6%). This study revealed that ghrelin rs35681 might be related to the occurrence of obesity associated with PCOS, and allele A was found to increase the risk of obesity in PCOS.

Polycystic Ovary Syndrome Signs and Metabolic Syndrome in Premenopausal Hispanic/Latina Women: the HCHS/SOL Study.

CONTEXT: Polycystic ovary syndrome (PCOS), a condition of androgen excess in women, is associated with cardiometabolic risk factors; however, this association is not fully characterized in a population-based sample of premenopausal women and high-risk groups such as Hispanics/Latinas. OBJECTIVE: We examined the association of PCOS signs and metabolic syndrome (MetS) in premenopausal Hispanic/Latina women. METHODS: This cross-sectional analysis includes 1427 women age 24 to 44 years from the Hispanic Community Health Study/Study of Latinos. PCOS signs included menstrual cycle greater than 35 days or irregular, self-reported PCOS, and oral contraceptive use to regulate periods or acne, and a composite of 1 or more PCOS signs. We calculated odds ratios (OR) and 95% CI for MetS, accounting for sociodemographic factors and the complex survey design; an additional model included body mass index (BMI). RESULTS: The mean age was 34 years and 30% reported any PCOS sign. The odds of MetS were higher in women reporting cycles greater than 35 days or irregular (OR 1.63; CI: 1.07-2.49) vs cycles 24 to 35 days, self-reported PCOS (OR 2.49; CI: 1.38-4.50) vs no PCOS, and any PCOS sign (OR 1.58; CI: 1.10-2.26) vs none. We found no association between OC use to regulate periods or acne and MetS (OR 1.1; CI: 0.6-1.8). When adjusting for BMI, only the association of self-reported PCOS and MetS was attenuated (OR 1.78; CI: 0.92-3.44). CONCLUSIONS: In Hispanic/Latina women, irregular menstrual cycles, self-reported PCOS, and any PCOS sign were associated with MetS and could indicate women at metabolic disease risk.

Polycystic ovary syndrome, medical semantics, and the political ecology of health in India.

Within public health, investigations into the rise of metabolic syndrome disorders, such as obesity and type II diabetes, following on the heels of globalisation have tended to focus on the twin axes of diet and physical exercise. However, such a limited focus obscures wider transformations in bodily and health-related practices that emerge in response to globalisation. This paper is an exploration of public discourses about PCOS-a hormonal disorder that affects menstruation, is associated with obesity, heart disease, and type II diabetes, and has been on the rise in India since the liberalisation of its economy in 1991- and it examines the concerns regarding sociocultural, environmental, and political-economic changes brought by liberalisation that these discourses index. Attention to medical semantics, as revealed through public discourses about PCOS, can help counter the limited focus of diet and physical activity-centred models through an emphasis on the political ecology of health. Such engagement can reveal how an emerging relationship between the body and its environment, which is seen as characteristically modern, is implicated in the rise of metabolic disorders. It can also offer critical insights for biomedical and public health research into such disorders.

Cultural Experiences, Patterns, and Practices of American Indian Women With Polycystic Ovary Syndrome: An Ethnonursing Study.

Introduction: Knowledge is needed about the cultural experiences, patterns, and practices of American Indian women with polycystic ovary syndrome (PCOS), so nurses can provide culturally congruent care. Method: A qualitative, ethnonursing study based on Leininger's theory of culture care diversity and universality. Data were collected from 13 key informants living on a reservation in the Western United States. Data were analyzed with Leininger's four phases of qualitative analysis. Results: Three universal themes were identified: (1) control of PCOS symptoms is important for the cultural well-being of tribal women, (2) culturally congruent PCOS education and health care are important with variations in approaches to treatment, and (3) tribal culture is important with variations in use of tribal practices. Discussion: Tribal culture affects the health care beliefs and practices of American Indian women with PCOS. The findings can be used to improve culturally congruent care for women with this chronic condition.

Association of GWAS identified INSR variants (rs2059807 & rs1799817) with polycystic ovarian syndrome in Indian women.

Polycystic ovary syndrome (PCOS), a gynaecological endocrine disorder affects 9% of Indian women and is linked to type II diabetes. The association of INSR (INSulin Receptor gene) variants (rs2059807 and rs1799817) with PCOS was established through genome-wide association studies, yet requires validation for the Indian population. This case-control study included 253 PCOS women and 308 age-matched control. The minor allele frequency of rs2059807 had an odds ratio of 13.5 and that of rs1799817 was 11.8. The cohort with rs2059807 MAF presented elevated levels of luteinising hormone [PCOS vs Control: 6.32 ± 2.26 mIU/mL vs 4.97 ± 3.27 mIU/mL], estradiol [116.01 ± 60.63 pg/mL vs 65.04 ± 44.98 pg/mL], and decreased HDL - C [50.4 ± 11.59 mg/dL vs 64 ± 15.49 mg/dL] showing disturbances in the hormonal patterns. The rs1799817 polymorphism cohort had elevated levels of serum insulin [17.99 ± 11.6 mIU/mL vs 11.67 ± 6.63 mIU/mL], blood glucose [199.15 ± 63.72 mg/dL vs 96.6 ± 24.3 mg/dL], and testosterone [0.91 ± 0.2 nmol/L vs 0.53 ± 0.16 nmol/L] thereby triggering metabolic dysfunction and predisposed to lifestyle disorder. Also, the SNPs were found to be in linkage equilibrium and contributed to the development of PCOS differentially.

Triglycerides as a Metabolic Target in Afrocaribbean Infertile Women with Polycystic Ovary Syndrome.

Background: Polycystic ovary syndrome (PCOS) is classically associated with insulin resistance, metabolic syndrome, or type 2 diabetes. Infertile Afrocaribbean (AC) women with PCOS may have metabolic features that could help to better target their management. Objective: To evaluate the characteristics of PCOS in this population and their metabolic profile to target the worst metabolic parameter. Methods: A retrospective study including infertile AC women for 4 years. PCOS was diagnosed using Rotterdam criteria and compared with non-PCOS women referred consecutively for infertility during the same period. Results: Among 981 AC women evaluated for infertility, PCOS was found in 17%. PCOS women were younger than non-PCOS women. After age and body mass index (BMI) matching, only fasting blood glucose and triglyceride levels were higher in PCOS women compared with non-PCOS women. PCOS was positively correlated with triglyceride levels and negatively with vitamin D levels. PCOS women with obesity had low high-density lipoprotein-cholesterol and increased triglyceride levels compared with those without obesity. No correlation was found between lipids or glucose levels and androgen levels. Multivariate analysis showed that only triglycerides were independently related to PCOS after adjustment for age and BMI. Conclusions: In the AC population where the prevalence of obesity and diabetes is increased, the metabolic profile of infertile women with PCOS is mainly characterized by hypertriglyceridemia, with a higher risk of visceral obesity and nonalcoholic fatty liver disease. Interventional studies would be useful to evaluate the predictive value of hypertriglyceridemia on diabetes and cardiovascular diseases in this population.

Phenotype and genotype of polycystic ovary syndrome in Asia: Ethnic differences.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder in reproductive-aged women, and ethnic diversity has been reported in its manifestation. This review addressed phenotype and genetic studies in Asian women with PCOS. Generally, East Asians are less hirsute, and the hirsutism score cutoff is lower than the Caucasian counterpart. It is not clear whether there are any significant differences in the prevalence or severity of irregular menstruation (IM) or characteristics of polycystic ovary (PCO) across ethnicities. Interestingly, the IM/PCO subgroup is a relatively common phenotype in East Asian patients but not in Caucasian patients. The prevalence of insulin resistance in PCOS patients varies depending on the index used and the cutoff, but women with PCOS showed a higher degree of insulin resistance than those of controls across ethnicities. Lower body mass index (BMI) and lower prevalence of metabolic syndrome were reported in East Asian patients, but despite lower BMI, a comparative study reported that Asian women with PCOS were more likely to have diabetes compared with Caucasian patients, suggesting they also have metabolic complications. Unlike East Asian patients, South Asian patients showed an increased degree of hirsutism, early onset of symptoms, and severe insulin resistance and metabolic risks compared with Caucasians. Genetic components play important roles in the pathogenesis of PCOS, and genome-wide association studies of PCOS suggest that similar genetic risk factors exist between Asian and Caucasian patients. Continuous comparative studies are needed to standardize the diagnosis and management of PCOS across different ethnicities.

Using the Medicine Wheel Model to Study Polycystic Ovary Syndrome in American Indian Women.

Developing a nursing research project with American Indian tribes and navigating the institutional review board approval process can appear daunting to investigators because of tribal research requirements in addition to academic requirements. Nurse investigators conducted a research project exploring experiences of American Indian women with polycystic ovary syndrome. After successful implementation of the project, a model emerged to guide researchers working with tribal communities through project development and the institutional review board process. The model is based on the American Indian medicine wheel with each quadrant aligned with a season of the year: spring, summer, fall, and winter. The seasonal approach divides project development into sections that can be developed independently or simultaneously. The model emphasizes collaborative relationships between the research team and tribe. Researchers can adapt and customize the model for their projects based on their objectives and targeted populations. The purpose of this article is to describe the medicine wheel model and, as an exemplar, demonstrate application of the model in a project involving American Indian women with polycystic ovary syndrome. Additionally, potential implications of the model for nursing research, education, and practice are presented.

Defining polycystic ovary syndrome phenotype in Vietnamese women.

AIM: This study aimed to evaluate the unique phenotype of the Vietnamese polycystic ovarian syndrome (PCOS) population. METHODS: In this multicenter cross-sectional descriptive study, a total of 901 reproductive-age women were recruited at three medical centers in Vietnam from June 2016 to May 2018. Group I included 479 patients with PCOS (Rotterdam 2003 consensus) and Group II included 422 non-PCOS women, consisted of women with regular menstrual cycle, collected at the same time of PCOS recruitment, without ovarian disease or ovarian failure. Main outcome measures were anthropomorphic, serum hormone, ultrasound and physical characteristics of PCOS. RESULTS: The Vietnamese PCOS population was lean, but with a higher weight and body mass index compared to controls. About 34.4% of PCOS subjects had hirsutism, primarily confined to the leg, arm and pubis. The PCOS population had higher serum luteinizing hormone (LH), LH : follicle stimulating hormone ratio, anti-Mullerian hormone and testosterone. The PCOS population had double the ovarian volume compared to controls. PCOS subjects had no increase in metabolic disease history and had on average optimal serum markers for low metabolic disease risk. Group D (O + polycystic ovary morphology [PCOM]) was the most prevalent phenotype noted in our Vietnamese PCOS cohort (67.6%). Modified Ferriman-Gallwey, levels of LH, testosterone and anti-Mullerian hormone were highest in Group A (O + H + PCOM) and lowest in Group D (O + PCOM). CONCLUSION: The Vietnamese PCOS population is characterized by a lean body type, nonfacial hirsutism, anovulatory, enlarged ovaries and typical PCOS serum hormone markers, low risk factors for metabolic syndrome. Nonclassical phenotypes for PCOS were more frequent than the classic phenotype.
