Risk of Bowel Obstruction after Hysterectomy for Benign Indication According to Surgical Method in Denmark, 1984-2013.

STUDY OBJECTIVE: To estimate the risk of bowel obstruction (BO) after hysterectomy for benign indications depending on the surgical method (abdominal, vaginal, or laparoscopic) and identify risk factors for adhesive BO. DESIGN: A national registry-based cohort. SETTING: Danish hospitals during the period 1984-2013. PATIENTS: Danish women who underwent hysterectomy for benign indications (N = 125 568). INTERVENTIONS: Abdominal hysterectomies were compared with vaginal hysterectomies, laparoscopic hysterectomies, and minimally invasive (vaginal and laparoscopic) hysterectomies. MEASUREMENTS AND MAIN RESULTS: The incidence of BO according to the surgical method was compared using Cox proportional hazard regression. The covariates included were the time period, age, concomitant operations, previous abdominal surgery or disease, and socioeconomic factors. In a subanalysis (n = 35 712 women) of the period 2004-2013, detailed information from the Danish Hysterectomy Database enabled the inclusion of patient-, surgery-, and complication-related covariates. The overall crude incidence of BO was 17.4 of 1000 hysterectomies (2196 incident cases). The 10-year cumulative incidence of BO differed among the surgical routes (abdominal, 1.7%; laparoscopic, 1.4%; and vaginal, 0.9%). In multiple-adjusted analyses, the risk of BO was higher after abdominal hysterectomy than after vaginal (hazard ratio 1.64 [95% confidence interval, 1.39-1.93]) and minimally invasive (vaginal or laparoscopic) hysterectomy (hazard ratio 1.54 [1.33-1.79]). Additional pre-existing risk factors for BO at the time of hysterectomy were increased age, low education, low income, smoking, high American Society of Anesthesiologists comorbidity score, history of infertility, abdominal infection, and previous abdominal surgery (apart from cesarean section), penetrating lesions in abdominal organs, or operative adhesiolysis. Perioperative risk factors at the time of hysterectomy included concomitant removal of the ovaries, adhesiolysis, blood transfusion, readmission, and overall presence of perioperative complications. CONCLUSION: Abdominal hysterectomy is associated with a 54% higher risk of BO than minimally invasive (laparoscopic or vaginal) hysterectomy.

Mechanisms Underlying Absent Training-Induced Improvement in Insulin Action in Lean, Hyperandrogenic Women With Polycystic Ovary Syndrome.

Women with polycystic ovary syndrome (PCOS) have been shown to be less insulin sensitive compared with control (CON) women, independent of BMI. Training is associated with molecular adaptations in skeletal muscle, improving glucose uptake and metabolism in both healthy individuals and patients with type 2 diabetes. In the current study, lean hyperandrogenic women with PCOS (n = 9) and healthy CON women (n = 9) completed 14 weeks of controlled and supervised exercise training. In CON, the training intervention increased whole-body insulin action by 26% and insulin-stimulated leg glucose uptake by 53% together with increased insulin-stimulated leg blood flow and a more oxidative muscle fiber type distribution. In PCOS, no such changes were found, despite similar training intensity and improvements in VO2max In skeletal muscle of CON but not PCOS, training increased GLUT4 and HKII mRNA and protein expressions. These data suggest that the impaired increase in whole-body insulin action in women with PCOS with training is caused by an impaired ability to upregulate key glucose-handling proteins for insulin-stimulated glucose uptake in skeletal muscle and insulin-stimulated leg blood flow. Still, other important benefits of exercise training appeared in women with PCOS, including an improvement of the hyperandrogenic state.

Multistrain Probiotic Increases the Gut Microbiota Diversity in Obese Pregnant Women: Results from a Randomized, Double-Blind Placebo-Controlled Study.

BACKGROUND: Maternal obesity is associated with adverse pregnancy outcomes. Probiotic supplementation during pregnancy may have positive effects on blood glucose, gestational weight gain (GWG), and the risk of gestational diabetes mellitus [GDM and glycated hemoglobin (HbA1c)]. OBJECTIVES: This feasibility study involved a daily probiotic intervention in obese pregnant women from the early second trimester until delivery. The primary aim was to investigate the effect on GWG and maternal glucose homeostasis (GDM and HbA1c). Secondary aims were the effect on infant birth weight, maternal gut microbiota, and other pregnancy outcomes. METHODS: We carried out a randomized double-blinded placebo-controlled study in 50 obese pregnant women. Participants were randomly allocated (1:1) to multistrain probiotic (4 capsules of Vivomixx®; total of 450 billion CFU/d) or placebo at 14-20 weeks of gestation until delivery. Participants were followed with 2 predelivery visits at gestational week 27-30 and 36-37 and with 1 postdelivery visit. All visits included blood and fecal sampling. An oral-glucose-tolerance test was performed at inclusion and gestational week 27-30. RESULTS: Forty-nine participants completed the study. Thirty-eight participants took >80% of the capsules (n = 21), placebo (n = 17). There was no significant difference in GWG, GDM, HbA1c concentrations, and infant birth weight between groups. Fecal microbiota analyses showed an overall increase in α-diversity over time in the probiotic group only (P = 0.016). CONCLUSIONS: Administration of probiotics during pregnancy is feasible in obese women and the women were willing to participate in additional study visits and collection of fecal samples during pregnancy. Multistrain probiotic can modulate the gut microbiota in obese women during pregnancy. A larger study population is needed to uncover pregnancy effects after probiotic supplementation. This trial was registered at clincaltrials.gov as NCT02508844.

Persistence of cervical high-risk human papillomavirus in women living with HIV in Denmark - the SHADE.

BACKGROUND: Women living with HIV (WLWH) have high rates of persistent high-risk human papillomavirus (hrHPV) infections and cervical cancer. We aimed to assess the distribution of hrHPV genotypes, risk factors of type-specific hrHPV persistence, and high-grade squamous intraepithelial lesions or worse (≥HSIL) in WLWH in Denmark. METHODS: From the prospective Study on HIV, cervical Abnormalities and infections in women in Denmark (SHADE) we identified WLWH with a positive hrHPV test during the study period; 2011-2014. HIV demographics were retrieved from the Danish HIV Cohort Study and pathology results from the The Danish Pathology Data Bank. Logistic regression was used to identify risk factors associated with persistent hrHPV infection (positivity of the same hrHPV type in two samples one-two years after the first hrHPV positive date) and ≥ HSIL. RESULTS: Of 71 WLWH, 31 (43.7%) had persistent hrHPV infection. Predominant hrHPV genotypes were HPV58, 52, 51, and 35 and most frequently observed persistent genotypes were HPV52, 33 and 31. CD4 < 350 cells/µL predicted genotype-specific hrHPV persistence (adjusted OR 4.36 (95%CI: 1.18-16.04)) and ≥ HSIL was predicted by prior AIDS (adjusted OR 8.55 (95% CI 1.21-60.28)). CONCLUSIONS: This prospective cohort study of well-treated WLWH in Denmark found a high rate of persistent hrHPV infections with predominantly non-16/18 hrHPV genotypes. CD4 count < 350 cells/µL predicted hrHPV persistence, while prior AIDS predicted ≥HSIL.

Danish doctors' reactions to 'internationalization' in clinical training in a public university hospital.

OBJECTIVE: From 2012 to 2015, two Departments of Obstetrics and Gynecology and two Departments of Pediatrics at the University of Copenhagen implemented an English medium international project. The project allowed international students to work in pairs with local Danish speaking students in a clinical setting. The student cohort was supported by Danish doctors who were responsible for student-pair supervision in English and, ultimately, patient care. Drawing on survey responses of 113 Danish doctors, this study considers the doctors' overall evaluation of the program and their perception of the international students' knowledge, skills and attitudes compared with local students. RESULTS: The Danish doctors rated the international and local students comparable in respect to professional commitment (p = 0.347), academic level (p = 0.134), and English proficiency (p = 0.080). The Danish doctors rated the international students significantly lower than the local students regarding communication with Danish doctors, other hospital staff, and patients (p < 0.001 in all cases). Ninety percent of the doctors involved in the project supported continuing working with internationalization if it included mixed pairs of students and a Danish doctor assigned each day to be exclusively responsible for student supervision. Language barriers for international medical students could be overcome but required substantial faculty support.

Prevalence and treatment of group B streptococcus colonization based on risk factors versus intrapartum culture screening.

OBJECTIVES: To estimate the prevalence of group B streptococcus at onset of labor and to compare the accuracy of intrapartum antibiotic prophylaxis based on a risk factor strategy versus an intrapartum screening. STUDY DESIGN: In this cross-sectional study, 700 women referred for intended vaginal delivery were tested for group B streptococcus at onset of labor by gold standard culture in vaginal and rectal swabs. The results were blinded, and intrapartum antibiotic prophylaxis was given to women with risk factors for group B streptococcus infection: previous neonatal group B streptococcus infection, group B streptococcus in urine and/or vagina in current pregnancy, gestational age <36 + 0 weeks, temperature ≥38.0 °C or rupture of membranes ≥18 h. RESULTS: Of 642 women, who delivered within three days of specimen collection, 170 (26.5%) received benzylpenicillin as intrapartum antibiotic prophylaxis based on risk factors. The prevalence of group B streptococcus at onset of labor was 17.8% (114/642), with 62 women positive for group B streptococcus in both the vagina and rectum, 12 in the vagina only and 40 in rectum only. Intrapartum antibiotic prophylaxis was administered correctly in 31.6% (36/114) of GBS positive women at time of delivery and 78.8% (134/170) of women who received antibiotics were actually GBS negative. The positive predictive value of intrapartum antibiotic prophylaxis based on risk factors was 21.2%. The sensitivity was 31.6% and the specificity was 74.6%. CONCLUSION: The accuracy of predicting maternal group B streptococcus infection from risk factors is low. Intrapartum group B streptococcus diagnostics is more precise and will not increase the overall use of intrapartum antibiotic prophylaxis.

Risk of adhesive bowel obstruction after abdominal surgery. A national cohort study of 665,423 Danish women.

BACKGROUND: Adhesive bowel obstruction is associated with considerable morbidity and mortality, but the magnitude of the risk is debated. METHOD: In a national cohort of all Danish women with an abdominal operation (N = 665,423) between 1977 and 2013, the risk of adhesive bowel obstruction was assessed by Cox multiple regression. Covariates were the number of abdominal operations, the surgical methods, the anatomical site involved, and the calendar year. RESULTS: In the cohort, 1.4% experienced an episode of adhesive bowel obstruction. The risk increased 33-43% during the study period, was lower after gynecological and obstetrical procedures compared to gastrointestinal (HR 0.36 [0.34-0.38]), lower after laparoscopic compared to laparotomic surgery (HR 0.51 [0.48-0.54]) and increased proportionally after each additional operation. CONCLUSIONS: The risk of adhesive bowel obstruction after abdominal operations depends on the site of earlier operations, the method of access and the number of earlier operations.

Molecular Mechanisms in Skeletal Muscle Underlying Insulin Resistance in Women Who Are Lean With Polycystic Ovary Syndrome.

CONTEXT: Skeletal muscle molecular mechanisms underlying insulin resistance in women with polycystic ovary syndrome (PCOS) are poorly understood. OBJECTIVE: To provide insight into mechanisms regulating skeletal muscle insulin resistance in women who are lean with PCOS. PARTICIPANTS AND METHODS: A hyperinsulinemic-euglycemic clamp with skeletal muscle biopsies was performed. Thirteen women who are lean who have hyperandrogenism and PCOS and seven age- and body mass index-matched healthy control subjects were enrolled. Skeletal muscle protein expression and phosphorylation were analyzed by Western blotting and intramuscular lipid content was measured by thin-layer chromatography. RESULTS: Women with PCOS had 25% lower whole-body insulin sensitivity and 40% lower plasma adiponectin concentration than in control subjects. Intramuscular triacylglycerol, sn-1.3 diacylglycerol, and ceramide contents in skeletal muscle were higher (40%, 50%, and 300%, respectively) in women with PCOS than in control subjects. Activation of insulin signaling did not differ between groups. In women with PCOS, the insulin-stimulated glucose oxidation was reduced and insulin-stimulated dephosphorylation of pyruvate dehydrogenase (PDH) Ser293 was absent. AMP-activated protein kinase (AMPK) α2 protein expression and basal Thr172 phosphorylation were 45% and 50% lower in women with PCOS than in control subjects, respectively. CONCLUSIONS: Whole-body insulin resistance in women who are lean who have hyperandrogenism and PCOS was not related to changes in the proximal part of the insulin signaling cascade in skeletal muscle despite lipid accumulation. Rather, reduced insulin sensitivity was potentially related to plasma adiponectin levels playing a modulating role in human skeletal muscle via AMPK. Furthermore, abnormal PDH regulation may contribute to reduced whole-body metabolic flexibility and thereby insulin resistance.

Are previous episodes of bacterial vaginosis a predictor for vaginal symptoms in breast cancer patients treated with aromatase inhibitors?

Objective To estimate the prevalence of vaginal symptoms in postmenopausal women with breast cancer exposed to aromatase inhibitors, and to investigate if the risk of vaginal symptoms is associated with previous episodes of bacterial vaginosis. Methods Patients from Rigshospitalet and Herlev University Hospital, Denmark, were identified through the register of Danish Breast Cancer Cooperation Group and 78 patients participated in the study. Semiquantitave questionnaires and telephone interview were used to assess the prevalence of vaginal symptoms and previous episode(s) of bacterial vaginosis. Multivariable logistic regression models were used to assess the association between vaginal symptoms and previous episodes of bacterial vaginosis. Results Moderate to severe symptoms due to vaginal itching/irritation were experienced by 6.4% (95% CI: 2.8-14.1%), vaginal dryness by 28.4% (95% CI: 19.4-39.5%), and dyspareunia by 23.1% (95% CI: 11.0-42.1%). Patients with earlier episodes of bacterial vaginosis had an increased risk of vaginal dryness when exposed to a treatment with an aromatase inhibitor, adjusted OR 5.5 (95% CI 1.3-21.6). Conclusion A considerable number of patients exposed to aromatase inhibitor have vaginal symptoms and the risk is highest among patients with earlier episodes of bacterial vaginosis.

Excessive gestational weight gain in first trimester is a risk factor for exacerbation of asthma during pregnancy: A prospective study of 1283 pregnancies.

BACKGROUND: Acute exacerbation during pregnancy is the most important risk factor for an unfavorable outcome of pregnancy in women with asthma. OBJECTIVE: We sought to identify pregnancy-related risk factors for acute exacerbations of asthma during pregnancy. METHODS: Since 2007, all pregnant women referred to give birth at Hvidovre Hospital, Denmark, have been offered participation in the prospective Management of Asthma during Pregnancy (MAP) program. Women were included in the present analysis if they fulfilled the following criteria: (1) diagnosed with asthma, (2) prescribed at least rescue bronchodilator, and (3) had the first visit to the respiratory outpatient clinic within the first 18 weeks of pregnancy. Data were analyzed using multiple logistic regression models with backward stepwise elimination (Proc Logistic procedure in SAS). RESULTS: Over an 8-year study period, a total of 1283 pregnancies in 1208 women fulfilled the criteria for inclusion in the MAP cohort. Women with asthma exacerbation(s) had larger gestational weight gain (GWG) in the first trimester of pregnancy (P < .001) and increased total GWG (P < .001) compared with women without exacerbation. More than 5 kg first-trimester weight gain was associated with an increased risk of asthma exacerbation (odds ratio, 9.35; 95% CI, 6.39-13.68; P < .001), and the risk increased in a dose-dependent manner with additional weight gain in excess of 5 kg. CONCLUSIONS: Excessive GWG in the first trimester is a risk factor for asthma exacerbation during pregnancy and the risk increases in a dose-dependent manner with increasing GWG.

Obstetrical complications in dichorionic twin pregnancies in women with polycystic ovary syndrome.

INTRODUCTION: Both women with polycystic ovary syndrome (PCOS) and women with twin pregnancies have increased risk of adverse pregnancy outcome. The aim of this study was to investigate the impact of PCOS and maternal androgen levels on the outcome of dichorionic twin pregnancy. MATERIAL AND METHODS: A retrospective study of 360 women with dichorionic twin pregnancies: 72 women with PCOS from a fertility clinic (years 1997-2010) and 288 women without PCOS from a hospital cohort (years 2005-2007). The obstetrical outcome was extracted from Danish National registers and supplemented by patient file data. In all, 65% of the PCOS group had a registered prepregnancy androgen level and these were stratified into normoandrogenic and hyperandrogenic women. The groups were compared by multiple regression analysis adjusting for mode of conception and prepregnancy body mass index. RESULTS: We found no overall impact of PCOS on the pregnancy outcome; the risks of preeclampsia, gestational diabetes and preterm delivery were comparable within the groups. However, five deliveries in the PCOS group compared with two in the control group occurred before gestational week 28. No difference in the obstetrical outcome between hyperandrogenic and normoandrogenic women was found. The body mass index in the PCOS population was lower than in the non-PCOS, possibly reflecting a higher socioeconomic status and a healthier lifestyle, which may underestimate the impact of a PCOS diagnosis. CONCLUSION: Neither PCOS nor maternal androgen levels confer additional risks to the outcome of dichorionic twin pregnancies of normal weight women.

Postpartum airway responsiveness and exacerbation of asthma during pregnancy - a pilot study.

BACKGROUND: Airway responsiveness and inflammation are associated with the clinical manifestations of asthma and the response to pharmacological therapy. OBJECTIVE: To investigate if airway responsiveness and inflammatory characteristics are related to asthma exacerbations during pregnancy. MATERIALS AND METHODS: In women with asthma who were prescribed controller medication and monitored closely during pregnancy, the risk of exacerbations was analyzed in relation to postpartum measures of fractional exhaled nitric oxide (FENO), skin prick test reactivity, static and dynamic lung volumes, diffusing capacity for carbon monoxide, bronchial responsiveness to inhaled mannitol, and inflammatory characteristics in induced sputum. Obtained data were analyzed in relation to exacerbation status during pregnancy. The PD15 is defined as the cumulative administered dose causing a 15% decline in forced expiratory volume in the first second (FEV1). RESULTS: Fifty women (mean age ± standard deviation of 32±5 years) were enrolled over an 11-month period and examined on average 4 months postpartum. During pregnancy, 13 women had a total of 16 exacerbations (8 mild and 8 severe). Women with asthma exacerbation during pregnancy had more pronounced airway responsiveness to inhaled mannitol (geometric mean PD15 82 vs 171 mg, p=0.04) and were less likely to be atopic (62% vs 86%, respectively; p=0.04) than the non-exacerbators. No statistically significant difference was found between the 2 groups of women with regard to type of airway inflammation in sputum and fractional exhaled nitric oxide (FENO). CONCLUSION: More pronounced airway hyperresponsiveness together with nonatopic status appears to characterize women at high risk of exacerbation of asthma during pregnancy.

The Impact of Upper Abdominal Pain During Pregnancy Following a Gastric Bypass.

OBJECTIVE: The aim of the present study was to describe the risk of internal herniation (IH) and the obstetric outcome in pregnant women with Roux-en-Y gastric bypass (RYGB) and episodes of upper abdominal pain. METHODS: The cohort included 133 women with RYGB: 94 with 113 pregnancies, from the local area referred for routine antenatal care (local cohort) and 39 with 40 pregnancies referred from other hospitals for specialist consultation due to RYGB. RYGB was mainly performed without closure of the mesenteric defects. Data collected from medical records were episodes of upper abdominal pain, pregestational and gestational abdominal surgery and pregnancy outcome. The risk of upper abdominal pain was estimated in the local cohort. Surgical intervention, IH and obstetric outcome according to pain were evaluated for 139 pregnancies with delivery of a singleton after 24 weeks of gestation (birth cohort). RESULTS: Upper abdominal pain complicated 42/113 (37.2 %) pregnancies in the local cohort and 11 women (9.7 %) had IH. In the birth cohort, upper abdominal pain complicated 64/139 (46.0 %) pregnancies; surgery was performed in 30/64 (46.9 %), and IH diagnosed in 21/64 (32.8 %). The median gestational age at onset of pain was 25 + 3 weeks. Women reporting abdominal pain had a higher risk of preterm birth (n = 14/64 vs. 1/75, p < 0.005), lower median gestational length (269 vs. 278 days, p < 0.005) and lower median birth weight (3018 vs. 3281 g, p = 0.002) compared to women without abdominal pain. CONCLUSIONS: Upper abdominal pain during pregnancy is frequent among women with Roux-en-Y gastric bypass, is often due to IH and is associated with adverse pregnancy outcome.

The impact of gastric bypass surgery on sex hormones and menstrual cycles in premenopausal women.

Obesity has adverse effects on ovulation, menstrual cyclicity and oocyte development leading to clinical symptoms such as infertility and menstrual disorders. The Roux-en-Y gastric bypass (RYGB) leads to weight loss, improved insulin sensitivity and may improve ovarian function. In 31 premenopausal women, 18 eu- and 13 oligo-/amenorrhoic, we followed the changes in follicular phase sex hormones 3, 6 and 12 month after RYGB. The average weight loss during the first postoperative year was 39.6 kg. The insulin sensitivity and serum insulin improved markedly especially within the first three postoperative months. SHBG increased progressively and was doubled after 12 months. In contrast, total and free androgens and DHEA declined about 50% during the first three postoperative months and remained fairly constant hereafter. One year after surgery, 85% (11/13) of the women with oligo-/amenorrhea gained regular menstrual cycles. Our results indicate that some of the endocrine changes related to regulation of ovarian function occur very early after bariatric surgery.

Low risk of adverse obstetrical and perinatal outcome in pregnancies complicated by asthma: A case control study.

BACKGROUND: Asthma in pregnancy have been associated with an increased risk of pregnancy complications. Our aim was to estimate incidence and describe risk factors for adverse obstetrical and perinatal outcomes in pregnant women with asthma. METHODS: Women enrolled in the Management of Asthma during Pregnancy (MAP) program were each matched with three controls (i.e. consecutive women giving birth at our obstetrical service). Asthma severity was classified according to treatment step. Data on obstetrical and perinatal outcomes were obtained from medical records. Logistic regression analysis was applied, and findings expressed as odds ratios (OR) unadjusted and adjusted (adj) for BMI, age, parity, smoking, ethnicity and marital status. RESULTS: Nine-hundred-thirty-nine pregnancies in women with asthma (i.e. cases) were compared to 2.782 controls. Overall, the incidence of complications was low, although women with asthma had a statistically significant higher risk of pre-eclampsia (5% vs. 3%, ORadj 1.60, 95% CI 1.07-2.38; p = 0.02) and small for gestational age neonates (SGA) (ORadj 1.30, 95% CI 1.10-1.54; p < 0.01) compared to controls. Compared to mild asthma, more severe asthma was associated with a higher risk of SGA (60% vs 53%, ORadj. 1.30, 95% CI 1.10-1.54; p < 0.01). Women with asthma exacerbation during pregnancy tended to have a higher risk of severe pre-eclampsia (ORadj 3.33 95% CI 0.96-11.65, p = 0.06) compared to pregnancies without any exacerbations. CONCLUSION: The overall risk of adverse obstetrical and perinatal outcomes in pregnancies complicated by asthma is low compared to non-asthmatic women. Our observations suggest that enrollment into an asthma management program has a positive impact on overall pregnancy outcome.

Prevalence and distribution of cervical high-risk human papillomavirus and cytological abnormalities in women living with HIV in Denmark - the SHADE.

BACKGROUND: Women living with HIV (WLWH) are at increased risk of persistent human papillomavirus (HPV) infection, cervical dysplasia and cervical cancer compared with women from the general population (WGP). We assessed the prevalence and distribution of cervical high-risk (hr) HPV infection and cytological abnormalities in WLWH compared with WGP in Denmark. Predictors of HPV and cytological abnormalities were estimated in WLWH. METHODS: WLWH consecutively enrolled in the Study on HIV, cervical Abnormalities and infections in women in Denmark (SHADE) in 2011 and were examined for cervical HPV and cytological abnormalities. WLWH were matched on age and prior cytological findings with WGP from an earlier study. HIV demographics were retrieved from the nationwide Danish HIV Cohort Study. Logistic regression was used to estimate predictors of hrHPV and cytological abnormalities. RESULTS: Of 334 included WLWH 26.4 % were positive for hrHPV as opposed to 16.6 % WGP (p < 0.0001). WLWH had a higher number of multiple infections (>1 h genotype present) (38.5 % versus 25.7 %, p = 0.030). Hr genotypes in descending order of frequency were HPV58 (7.1 %), 52 (5.4 %), and 16 (4.8 %) in WLWH versus HPV16 (4.1 %), 52 (2.8 %) and 58 (2.4 %) in WGP. Predictors of hrHPV in WLWH were short duration of HAART (adjusted OR per year 0.90 (95 % CI 0.84-0.96)), AIDS prior to inclusion (adjusted OR 3.61 (95 % CI 1.75-7.46)), ≥5 lifetime sexual partners (adjusted OR 2.20 (95 % CI 1.08-4.49)), sexual debut <16 years of age (adjusted OR 2.05 (95 % CI 1.03-4.10)) and CD4 < 350 cells/µL (adjusted OR 2.53 (95 % CI 1.20-5.40)). Cytological abnormalities were prevalent in 10.4 % vs. 5.2 % (p = 0.0003) of WLWH and WGP. In WLWH with hrHPV, short duration of HAART predicted cervical dysplasia (adjusted OR per year 0.83 (95 % CI 0.71-0.97)). CONCLUSIONS: WLWH presented with more cervical hrHPV infections and cytological abnormalities, and a different distribution of hrHPV genotypes compared with WGP. Cervical hrHPV and cytological abnormalities were predicted by short duration of HAART.

Effects of probiotics (Vivomixx®) in obese pregnant women and their newborn: study protocol for a randomized controlled trial.

BACKGROUND: Maternal obesity is associated with increased risks of adverse pregnancy-related complications and outcomes for both mothers and infants. Overweight and obese women have an increased risk of pregnancy-induced hypertension, preeclampsia and gestational diabetes mellitus (GDM). Infant Body Mass index (BMI) and the risk of obesity in adulthood are related to maternal gestational weight gain (GWG). Preventive lifestyle and dietary interventions are time-consuming and do not always reduce GWG or the risk of maternal pregnancy complications. Recent research has indicated that the gut microbiota may play a significant role in the development of obesity. Some studies have indicated that the daily consumption of probiotics may reduce the risk of preeclampsia, maintain serum insulin levels and reduce the frequency of GDM in pregnant women. The aims of this study are to investigate whether daily probiotic supplements in obese women during pregnancy can limit gestational weight gain, improve glucose homeostasis and thereby improve maternal, fetal and infant health outcomes. METHODS: A pilot study including 50 obese pregnant nulliparous women with a prepregnancy BMI of between 30 and 35 kg/m2 will be randomized to receive daily probiotics (four capsules of Vivomixx®; total of 450 billion CFU/day, including eight probiotic bacterial strains) or placebo from gestational age 14-20 weeks until delivery. The infants will be followed until 9 months of age. The women will be monitored by weight, blood, fecal, vaginal and urine samples, diet questionnaires and hospital record review. Primary outcomes are: maternal weight gain, glycated hemoglobin (HbA1c) level and changes in glucose concentration measured during an oral glucose tolerance test. Secondary outcomes are: microbiota and inflammatory markers in mother and child, pregnancy complications, pregnancy outcomes, physical activity and the body composition of the neonate. DISCUSSION: We expect to find alterations in the metabolic profiles, microbiota and possibly pregnancy outcomes. From a clinical point of view the effects of Vivomixx® could control weight gain and reduce complications during pregnancy by inducing changes in the gut microbiota. Furthermore, this intervention during pregnancy could influence the infant's microbiota, which could have important implications for infant development and health.

A new model of paired clinical teaching of international and Danish medical students.

INTRODUCTION: Since 2006, one hospital has offered two clinical courses in obstetrics/gynaecology and paediatrics to international (I) students. However, as I-student enrolment increased, the hospital faced cut-backs. As from 2010, I-team course evaluations therefore dropped to unacceptable levels and more I- than Danish (DK) students failed exams. Therefore, in 2012 we started a three-year internationalisation project (I-project) at two hospitals. The primary intervention was to pair training for I- and DK-students at clinical contact, and to offer an exclusive daily lecturer for I-teams. METHODS: We compared the course evaluations and exam grades of I-teams and DK-teams for two years prior to (107 from I-teams - 211 participants from DK-teams) and during the I-project (245 participants from I-teams - 575 from DK-teams). RESULTS: During the I-project, the I-teams' course evaluations increased to acceptable values and to levels comparable to the evaluation scores of DK-teams. Furthermore, I-students now considered that their communication with the patients was acceptable. Before the I-project, I-students had lower exam grades (median = 10 (range: 0-12)) than DK-students (10 (4-12)) (p = 0.03), but during the I-project, exam grades increased to the levels achieved by DK-students (10 (2-12) - 10 (0-12) (p = 0.22), and no more I- than DK-students failed exams (p = 0.51). CONCLUSIONS: Pairing students for clinical training and allocating an exclusive lecturer for I-teams produced improved courses for internationalisation. Allocating an exclusive lecturer was associated with a cost of about 615 EUR per student per course when the team consisted of ten students.

A Time Interval of More Than 18 Months Between a Pregnancy and a Roux-en-Y Gastric Bypass Increases the Risk of Iron Deficiency and Anaemia in Pregnancy.

OBJECTIVE: The aim of the study is to explore the impact of time between Roux-en-Y gastric bypass (RYGB) and pregnancy on obstetrical outcome and nutritional derangements. METHODS: In a retrospective cross-sectional study of pregnant women admitted for antenatal care at two tertiary hospitals, we examined 153 women with RYGB and a singleton pregnancy of at least 24 weeks. The women were stratified according to a pregnancy <18 months (40 women) or ≥18 months (113 women) after RYGB. Main outcome measures were nutritional parameters and glycated haemoglobin 1Ac (HbA1c) in second and third trimester of pregnancy, gestational hypertension, length of pregnancy, mode of delivery and foetal birth weight. RESULTS: The two groups were comparable regarding age, parity and prepregnancy body mass index. The frequency of iron deficiency anaemia (ferritin <12 µg/L and haemoglobin <6.5 mmol/L/10.5 g/dL) was significantly higher in the late group, 29 vs. 8 % in the early group, p = 0.010. No differences were found for vitamin B12, vitamin D and zinc. Median HbA1c was significantly higher in the late group than in the early group (33 vs. 31 mmol/mol, p = 0.027). There were no significant differences in the risk of adverse pregnancy outcome or birth weight between the two groups. CONCLUSION: A long surgery-to-pregnancy time interval after a RYGB increases the risk of iron deficiency anaemia but not of other nutritional deficits. Time interval does not seem to have an adverse effect on the obstetrical outcome, including intrauterine growth restriction. Specific attention is needed on iron deficit with increasing surgery-to-pregnancy time interval.
