    Objective: To study the associations between androgens, glucose homeostasis, inflammation and statin treatment in women with polycystic ovary syndrome (PCOS). Design and methods: Oral glucose tolerance tests, androgens, hs-CRP and interleukin-1 receptor antagonist (IL-1Ra) were analyzed at baseline and after 6months of atorvastatin (20 mg/d) or placebo treatment in 27 women with PCOS. Results: Testosterone associated with insulin resistance measured with ISIMatsuda independently of BMI, age and SHBG concentrations and the full model, including IL-1Ra, hs-CRP and HDL-C, also showed independency of BMI and waist circumference (p≤.042). Free androgen index (FAI) associated with ISIMatsuda independently of adiposity (p≤.025) but in the full model with waist circumference the association was insignificant. ISIMatsuda decreased with testosterone >1.2nmol/l compared with lower levels at baseline (p=.043) and at six months (p=.003). Accordingly, 30-minute insulin levels were increased with moderately elevated testosterone independently of adiposity (p≤.046). Increased fasting glucose and AUC insulin associated with statin treatment independently of adiposity and the associations attenuated after adjusting for testosterone.  Conclusions: Moderately elevated testosterone concentrations together with obesity-related inflammatory factors modify glucose homeostasis by increasing insulin resistance and early insulin secretion.Peer reviewe

    Objective: To compare the metabolic profiles of normo- and hyperandrogenic women with polycystic ovary syndrome (PCOS) with those of control women at different ages during reproductive life. Design: Case-control study. Setting: Not applicable. Patient(s): In all, 1,550 women with normoandrogenic (n = 686) or hyperandrogenic (n = 842) PCOS and 447 control women were divided into three age groups: 39 years). Interventions(s): None. Main Outcome Measure(s): Body mass index (BMI), waist circumference, blood pressure, glucose, insulin, cholesterol, lipoproteins, triglycerides and high-sensitivity C-reactive protein. Result(s): Both normo- and hyperandrogenic women with PCOS were more obese, especially abdominally. They had increased serum levels of insulin (fasting and in oral glucose tolerance tests), triglycerides, low-density lipoprotein, and total cholesterol, higher blood pressure, and lower high-density lipoprotein levels independently from BMI compared with the control population as early as from young adulthood until menopause. The prevalence of metabolic syndrome was two-to fivefold higher in women with PCOS compared with control women, depending on age and phenotype, and the highest prevalence was observed in hyperandrogenic women with PCOS at late reproductive age. Conclusion(s): When evaluating metabolic risks in women with PCOS, androgenic status, especially abdominal obesity and age, should be taken into account, which would allow tailored management of the syndrome from early adulthood on.

    Sjukskötarutbildningens mål är att utbilda studenterna med en omfattande kunskap till sjuk-skötaryrkets centrala arbetsuppgifter. Den kliniska undervisningen skall förbereda studenten till hennes kommande yrke. I detta examensarbete undersöks studenternas upplevda kompetens av den kliniska undervisningen de fått från Arcada. Arbetet ingår i GROW-projektet där ett av de centrala målen var att utveckla den kliniska undervisningen. Syfte med arbetet är reda ut vad studenterna anser om sin kliniska kompetens som de erhållit under sin studietid. Följande frå-geställningar användes i arbetet: Vilka är studenternas erfarenheter av den kliniska undervis-ningen: med fokus på simulering och yrkespraktik? Hur kan den kliniska undervisningen ut-vecklas? Som teoretisk referensram användes P. Benners teori ’Från novis till expert’ och K. Erikssons modell av vårdprocessen. Arbetet är en kvantitativ enkätundersökning som gjordes via internet. Enkäten har 34 påståenden och en öppen fråga. I undersökningen deltog 38 stu-denter av 160. Vid bearbetningen av materialet användes SPSS-dataprogrammet. I resultatet stiger det fram hur studiepoäng inverkar på upplevd kompetens, ju mera studiepoäng desto högre upplevd kompetens. Den öppna frågan lyfter fram 3 huvudkategorier som studenterna ansåg att stöder deras inlärning: lärarens roll, praktisk övning och teoretisk bakgrund. På grund av att svarsprocenten blev så låg kan inte resultatet generaliseras men den kan ge en inblick i studenternas åsikter och upplevelser av den kliniska undervisningen.The aim of nursing education is to educate students with a comprehensive knowledge to the main work tasks in nursing. The purpose of clinical education is to prepare the student for her future profession. This thesis studies students’ experiences of the clinical education and the competence they get of it. This thesis is a part of Arcadas GROW-project. One of the main aims of the project was to develop the clinical education. The aim of this thesis is to explore students’ thoughts on their clinical competence regarding the education they obtained. The following questions were used in this study: What are students’ experiences of the clinical education: with focus on simulation and clinical practice? Are there development opportuni-ties in the clinical education? P. Benner ‘From novice to expert’ and K. Eriksson ‘The process of nursing’ was used as the theoretic frame of reference. The study is a quantitative survey that has 34 claims and one open question. 38 out of 160 students participated in the survey. SPSS was used to analyze the material. The result indicates that the higher the study points are; the higher students evaluate their clinical competence. The open questioner brings up three main categories: the roll of the educator, practical exercises and theoretical background. Because of a low amount of participants, the results cannot be generalized but they can help Arcadas administration to better understand how students look at the clinical education

    Abstract Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. The main features of the syndrome include menstrual irregularities and hyperandrogenism. In addition to symptoms related to fertility, some women also suffer from an unfavourable metabolic profile including impaired glucose tolerance, dyslipidaemia and low-grade chronic inflammation. In the present studies we aimed to investigate the role of age on adrenal and ovarian androgen secretion in 79 women with PCOS and 98 healthy women, with special focus on the menopause. Furthermore, we studied the effects of combined hormonal contraceptives (CHCs) administered orally, transdermally and vaginally (n=42, healthy women, 9 weeks) and atorvastatin treatment (n=28, women with PCOS, 6 months) on androgen levels and metabolic factors. Androgen secretion capacity was analysed by using adrenal and ovarian stimulation tests and glucose tolerance by using oral and intravenous glucose tolerance tests. Furthermore, chronic inflammation was assessed via assay of C-reactive protein and pentraxin-3. Basal and stimulated adrenal and ovarian androgen production was elevated and levels remained higher in women with PCOS compared with healthy women even after the menopause. Furthermore, women with PCOS presented with enhanced insulin resistance and chronic inflammation, which persisted beyond menopausal transition. During CHC treatment, the route of administration was insignificant, and all treatments impaired insulin sensitivity and increased chronic inflammation. In women with PCOS, treatment with atorvastatin improved chronic inflammation and the lipid profile as expected, but worsened glucose tolerance and did not affect testosterone levels. Regardless of strict exclusion criteria, where only relatively healthy women with PCOS were recruited, the results showed that enhanced androgen secretion and unfavourable metabolic alterations associated with PCOS persist through menopausal transition. The findings emphasize the importance of monitoring glucose metabolism during the use of CHCs, especially in women with known risks of type 2 diabetes. Atorvastatin treatment exacerbates insulin resistance in women with PCOS and therefore the treatment should only be considered after individual risk assessment of cardiovascular disease and not just because of PCOS.Tiivistelmä Monirakkulainen munasarjaoireyhtymä (PCOS) on hedelmällisessä iässä olevien naisten yleisin hormonaalinen ongelma. Tyypillisiä PCOS:n oireita ovat munarakkuloiden epäsäännöllisestä kypsymisestä johtuvat kuukautiskierron häiriöt ja miessukuhormonien eli androgeenien liikatuotanto. Hedelmällisyyttä heikentävien oireiden lisäksi PCOS:än liittyy aineenvaihdunnan ongelmia, kuten heikentynyttä sokerinsietoa sekä taipumus rasva-aineenvaihdunnan häiriöihin ja krooniseen tulehdukseen. Tutkimuksessa selvitettiin ikääntymisen ja vaihdevuosien vaikutuksia lisämunuais- ja munasarjaperäiseen androgeenieritykseen 79 PCOS-naisella ja 98 terveellä naisella. Lisäksi tutkittiin eri yhdistelmäehkäisyvalmisteiden antoreittien (suu, iho, emätin) (n=42, terveet naiset, 9 viikkoa) ja atorvastatiinihoidon (n=28, PCOS-naiset, 6 kuukautta) vaikutuksia androgeenitasoihin ja aineenvaihdunnallisiin muuttujiin. Androgeenieritystä tutkittiin lisämunuaisten ja munasarjojen stimulaatiotesteillä ja sokeriaineenvaihdunnan muutoksia suun kautta ja suonensisäisesti tehtävillä sokerirasituskokeilla. Tulehduksellista tilaa mitattiin määrittämällä C-reaktiivisen proteiinin ja pentraksiini-3:n pitoisuuksia. Lisämunuaisten ja munasarjojen androgeenieritys oli PCOS-naisilla lisääntynyt terveisiin naisiin verrattuna, ja ero säilyi vaihdevuosi-iän jälkeen. PCOS-naisilla esiintyi myös enemmän heikentynyttä sokerinsietoa ja kroonista tulehdusta vielä vaihdevuosi-iän jälkeenkin. Hormonaalinen yhdistelmäehkäisy heikensi insuliiniherkkyyttä sekä pahensi pitkäaikaista tulehdusta annostelureitistä riippumatta. Atorvastatiinihoito puolestaan paransi pitkäaikaista tulehdusta sekä rasva-aineenvaihduntaa PCOS-naisilla, mutta huononsi sokerinsietoa ja insuliiniherkkyyttä eikä sillä ollut vaikutusta testosteronitasoihin. Koska poissulkukriteerit olivat tiukat, tutkimuksiin valikoitui varsin terveitä PCOS-naisia. Siitä huolimatta osoittautui, että PCOS:än liittyvä lisääntynyt androgeenituotanto sekä epäedulliset aineenvaihdunnan muutokset jatkuvat vielä vaihdevuosi-iän jälkeen. Hormonaalisen yhdistelmäehkäisyn käytön aikana olisi hyvä seurata sokeriaineenvaihdunnan muutoksia erityisesti niillä naisilla, joilla on kohonnut riski sairastua aikuistyypin diabetekseen. Atorvastatiinihoito huonontaa PCOS-naisilla insuliiniherkkyyttä, minkä vuoksi hoito tulisi aloittaa vain yksilöllisen riskiarvion perusteella

    Racial and ethnic differences in the prevalence of metabolic syndrome and its components of metabolic syndrome in women with polycystic ovary syndrome : a regional cross-sectional study

    BACKGROUND: Polycystic ovary syndrome is a heterogeneous disorder and its presentation varies with race and ethnicity. Reproductive-age women with polycystic ovary syndrome are at increased risk of metabolic syndrome; however, it is not clear if prevalence of metabolic syndrome and clustering of its components differs based on race and ethnicity. Moreover, the majority of these women do not undergo routine screening for metabolic syndrome. OBJECTIVE: We sought to compare the prevalence of metabolic syndrome and clustering of its components in women with polycystic ovary syndrome in the United States with women in India, Brazil, Finland, and Norway. STUDY DESIGN: This is a cross-sectional study performed in 1089 women with polycystic ovary syndrome from 1999 through 2016 in 5 outpatient clinics in the United States, India, Brazil, Finland, and Norway. Polycystic ovary syndrome was defined by the Rotterdam criteria. Main outcome measures were: metabolic syndrome prevalence, blood pressure, body mass index, fasting high-density lipoprotein cholesterol, fasting triglycerides, and fasting glucose. Data from all sites were reevaluated for appropriate application of diagnostic criteria for polycystic ovary syndrome, identification of polycystic ovary syndrome phenotype, and complete metabolic workup. The US White women with polycystic ovary syndrome were used as the referent group. Logistic regression models were used to evaluate associations between race and metabolic syndrome prevalence and its components and to adjust for potential confounders, including age and body mass index. RESULTS: The median age of the entire cohort was 28 years. Women from India had the highest mean Ferriman-Gallwey score for clinical hyperandrogenism (15.6 +/- 6.5, P <.001). The age-adjusted odds ratio for metabolic syndrome was highest in US Black women at 4.52 (95% confidence interval, 2.46-8.35) compared with US White women. When adjusted for age and body mass index, the prevalence was similar in the 2 groups. Significantly more Black women met body mass index and blood pressure criteria (P <.001), and fewer met fasting triglycerides criteria (P <.05). The age- and body mass index-adjusted prevalence of metabolic syndrome was highest in Indian women (odds ratio, 6.53; 95% confidence interval, 3.47-12.30) with abnormalities in glucose and fasting high-density lipoprotein cholesterol criterion and in Norwegian women (odds ratio, 2.16; 95% confidence interval, 1.17-3.98) with abnormalities in blood pressure, glucose, and fasting high-density lipoprotein cholesterol criterion. The Brazilian and Finnish cohorts had similar prevalence of metabolic syndrome and its components compared to US White women. CONCLUSION: Despite a unifying diagnosis of polycystic ovary syndrome, there are significant differences in the prevalence of metabolic syndrome and clustering of its components based on race and ethnicity, which may reflect contributions from both racial and environmental factors. Our findings indicate the prevalence of metabolic syndrome components varies in women with polycystic ovary syndrome, such that compared to White women from the United States, Black US women had the highest prevalence, whereas women from India and Norway had a higher prevalence of metabolic syndrome independent of obesity. The differences in clustering of components of metabolic syndrome based on ethnicity highlight the need to routinely perform complete metabolic screening to identify specific targets for cardiovascular risk reduction strategies in these reproductive-age women.Peer reviewe
