Polycystic ovary syndrome and low-grade inflammation with special reference to YKL-40

Objective: To evaluate the plasma level of YKL-40 in a Danish polycystic ovary syndrome (PCOS) population and to investigate whether YKL-40 is associated with CVD risk factors such as waist circumference, body mass index (BMI), insulin resistance (IR), fasting glucose, fasting insulin, blood lipids and CRP.

Design: Cross-sectional study.

Setting: Gynecological clinics at three Danish University Hospitals.

Patients: One hundred seventy-one premenopausal women with PCOS recruited consecutively from April 2010 to February 2012. PCOS was diagnosed according to the Rotterdam criteria.

Main outcome measures: Plasma level of YKL-40 in four phenotypes of PCOS defined by BMI and IR.

Results: No statistically significant difference was observed in the plasma level of YKL-40 across the four BMI/IR-phenotypes. Positive associations were observed between YKL-40 and BMI, total and free testosterone, triglycerides, and CRP. Total and free testosterone were independent predictors of YKL-40.

Conclusion: YKL-40, the marker of low-grade inflammation is not increased in women with PCOS.     

ß-hCG and prediction of therapeutic success in ectopic pregnancies treated with methotrexate,results from a prospective observational study

Objective: To evaluate the diagnostic accuracy of different beta-human chorionic gonadotrophin (ß-hCG) levels measurement, for predicting success of medical treatment in cases diagnosed as tubal ectopic pregnancy (TEP).

Design: Five-year prospective observational study.

Setting: Prenatal Diagnosis Unit, Vall d'Hebron University Hospital – Barcelona.

Patients: TEP cases fulfilling criteria for medical treatment with Methotrexate.

Interventions: ß-hCG levels were measured on d 0, 4 and 7 of treatment. Results were compared by non-parametrical tests. A ROC curve was plotted to define cut-off points. Diagnostic accuracy of the different measurements was evaluated.

Main outcome measure: Failure of treatment defined as need for surgical treatment or persistence of high ß-HCG levels despite treatment.

Results: 126 women were diagnosed as TEP, eligible for medical treatment. There were no differences in parity, age, previous TEP, or adnexal mass size. Success rate was 88%. ß-HCG decreased significantly more, between days 0–7 and 4–7, in the successful cases. LR for success prediction was 6.2 and 7.8 for ß-HCG levels at days 4 and 7 respectively, 4.02 and 2.47 for decrement between days 0–7 (25%) and 4–7 (20%), respectively.

Conclusion: ß-hCG cutoff values have a potential for predicting a successful medical treatment of TEP.     

The influence of psychological factors on postpartum weight retention 12 months post-birth

Background

During the first postpartum year 20% of women retain excessive weight from pregnancy (postpartum weight retention; PPWR), which predicts long-term overweight/obesity.

Objective

The aim of this study was to explore the associations between psychological factors (depression, anxiety and stress symptoms and body attitudes) in late gestation and at 12-months postpartum with PPWR one-year post-birth.

Methods

Pregnant women (N = 176) completed questionnaires in early–mid pregnancy (Time 1; mean (SD) = 16.97 (1.35) weeks), late pregnancy (Time 2; mean (SD) = 33.33 (2.05) weeks), and one year postpartum (Time 3; mean (SD) = 53.12 (3.34) weeks). Women provided demographic characteristics, height and pre-pregnancy weight at Time 1. At Times 2 and 3, weight, depressive, anxiety and stress symptoms and body attitudes (salience of weight and shape, attractiveness, feeling fat, and strength and fitness) were assessed in addition to physiological, socio-contextual and lifestyle factors. Gestational weight gain and PPWR were calculated. Hierarchical linear regression models were conducted to explore variance in 12-month PPWR.

Results

Overall, models explained 26–39% variance in PPWR. Gestational weight gain in late pregnancy and low attractiveness at 12 months postpartum were the only variables associated significantly with 12-month PPWR.

Conclusion

While psychological factors did not appear to be important direct contributors to PPWR at 12 months, the overall contribution of all variables suggests that such factors may be implicated in a small and incremental way. Exploration of the interactions between variables will help unpack potential mechanisms of the development of PPWR at 12 months post-birth.     

Transcervical Foley’s catheter versus Cook balloon for cervical ripening in stillbirth with a scarred uterus: a randomized controlled trial

Objective: To compare the efficacy and safety of the use of transcervical Foley’s catheter versus Cook cervical ripening balloon in pregnant women with stillbirth, unfavorable cervix and scarred uterus.

Design: Randomized controlled study.

Setting: El Minia University Hospital, El Minia, Egypt.

Patients and methods: Two-hundred pregnant women with stillbirth, unfavorable cervix and scarred uterus were recruited into this study. They were randomized into two groups. In group I (n?=?100), cervical ripening was done using Foley’s catheter. In group II (n?=?100), cervical ripening was done using Cook cervical ripening balloon.

Main outcome measures: Balloon insertion to delivery interval, successful ripening rate, cesarean delivery rate, maternal adverse events and maternal satisfaction.

Results: Time from balloon insertion to expulsion and from balloon insertion to delivery was significantly shorter in Foley’s catheter group. However, the difference between the two groups regarding time from balloon insertion to active labor, time from balloon expulsion to delivery, cervical ripening, cesarean section, instrumental delivery, pain score, need for analgesia, hospital stay and maternal satisfaction was not statistically significant.

Conclusions: Foley’s catheter and Cook cervical ripening balloon are comparable regarding efficacy and safety profile when used to ripen the cervix in pregnant women with stillbirth, unfavorable cervix and scarred uterus. However, Foley’s catheter has a shorter induction to delivery interval and is relatively cheaper device.     

Role of ultrasound in the management of diabetes in pregnancy

The purpose of this review is to discuss the established role of ultrasound (US) in the management of pregnancy complicated by diabetes mellitus (DM), as well as new developments with regard to the use of US in this situation. We choose to explore the role of US in pregnancy complicated by DM in three areas:

(1) Role of US in estimation of fetal weight.

(2) Role of US in diagnosis of congenital malformation.

(3) Role of US in monitoring diabetic pregnant patients.     

Micronized progesterone reduces vasoconstriction in the placenta

Objective: To investigate if micronized progesterone (P4) has the ability to attenuate thromboxane mimetic U46619-mediated fetoplacental artery vasoconstriction.

Methods: Paired cotyledons obtained from the same placenta of five-term subjects were analyzed. The fetal artery and maternal intervillous space of one cotyledon was infused with P4 while another cotyledon was infused with control perfusate. After 30?min, a bolus dose of U44619 was administered to both cotyledons.

Results: The change in the measured fetoplacental vascular pressure caused by bolus administration of U46619 was less in the cotyledons infused with P4 (p?=?0.009).

Conclusion: Continuous treatment with P4 significantly attenuates the U46619-mediated fetoplacental vasoconstriction.     

Morphological and functional aspects of acute kidney injury after fetal programing in the offspring of diabetic rats

Objective: To evaluate the effects of folic acid (FA)-induced renal failure in young offspring of diabetic mothers.

Methods: The offspring of streptozotocin-induced diabetic dams were divided into four groups: CC (controls receiving vehicle); DC (diabetics receiving vehicle); CA (controls receiving FA solution, 250?mg/kg) and DA (diabetics receiving FA solution, 250?mg/kg). Renal function tests and morphometry results were analyzed.

Results: An increase in creatinine and urea levels was observed in CA and DA groups at two and five months. FA administration caused a significant reduction in the number of glomeruli in the offspring of diabetic dams. The diabetes group treated with FA had fewer glomeruli compared to controls at two and five months. FA caused an increase in the area of the urinary space both in controls and offspring of diabetic dams at two and five months. The number of glomeruli and area of the urinary space at two months were negatively correlated.

Conclusions: Fetal programing promotes remarkable changes in kidney morphology and function in offspring. We suggest that the morphological changes in the kidneys are more pronounced when fetal programing is associated with newly acquired diseases, e.g. renal failure induced by FA.     

Comparison between resveratrol and cabergoline in preventing ovarian hyperstimulation syndrome in a rat model

Objective: The aim of this study is to investigate the effects of resveratrol in a rat model of ovarian hyperstimulation syndrome (OHSS) and compare with cabergoline.

Design: Randomized controlled, animal study.

Animal(s): Female Wistar rats.

Material and methods: A rat OHSS model was used to investigate the effects of resveratrol compare with cabergoline administration for preventing OHSS. Body weight, ovary weight, diameter, vascular permeability (VP), vascular endothelial growth factor (VEGF), cyclooxygenase-2 (COX-2) expression (immunohistochemistry), and serum estradiol (E2) levels were then compared.

Results: The ovarian VEGF concentration was significantly increased in the OHSS Groups (Groups 3–5) compared with the control groups (1 and 2). But vascular permeability, VEGF, and COX-2 expressions were reduced in animals treated with the resveratrol group compared with the cabergoline group (group 5) and the severe OHSS (group 3) group. Blood E2 levels were decreased in group treated with the resveratrol group compared with the cabergoline group (group 5) and severe the OHSS (group 3) group.

Conclusion(s): Our results in a rat model suggest that resveratrol has a beneficial effect on OHSS by reducing the increases in ovarian daimeter, VP, and VEGF expression associated with OHSS. These effects may be mediated by the COX-2 inhibitory capacity of resveratrol.     

Prognostic value of funisitis and/or chorionic vasculitis compared to histologic chorioamnionitis in full-term infants

Aim: To compare pathological findings in the placenta and cord with the prognosis of full-term infants in cases of neonatal infection and microbial analyses.

Methods: The pathological findings in the placenta and cord and microbial analyses of amniotic fluid and neonatal samples based on culture or polymerase chain reaction (PCR) were observed in 1208 full-term mother–infant pairs at our center. We also collected neonatal clinical infection data, such as the occurrence of septicemia and other infectious diseases.

Results: Neonatal infection and positive identification of microorganisms were more common in the funisitis and/or chorionic vasculitis group than in the histologic chorioamnionitis group.

Conclusion: Funisitis and/or chorionic vasculitis is a valuable pathological marker for assessing the comparison between intrauterine infection and neonatal inflammatory conditions in infants delivered at full-term.     

Does preeclampsia involve the pancreas? A report of original research

Objective: To analyze the effect, if any, of pregnancy-related hypertension on the pancreas.

Methods: A database of pregnant women with hyperbilirubinemia was reviewed for cases with serum amylase values. These cases were linked to a computerized obstetric database, and women were analyzed according to the diagnosis of preeclampsia.

Results: A total of 292 consecutive women with hyperbilirubinemia during pregnancy delivered at our institution between 2005 and 2011. Of these, 52 (18%) were diagnosed with preeclampsia, and in only nine was serum amylase abnormally elevated.

Conclusion: Using serum analytes as surrogates for organ injury, it appears preeclampsia infrequently affects the pancreas.     

Increase of neuronal injury markers Tau and neurofilament light proteins in umbilical blood after intrapartum asphyxia

Aim: Compare the levels of the brain injury biomarkers Tau and neurofilament light protein (NFL) in cases of asphyxia with those in controls.

Materials and methods: We analyzed the neuronal proteins Tau and NFL in umbilical blood of 10 cases of severe-moderate intrapartum asphyxia and in 18 control cases.

Results: The levels of both Tau and neurofilament were significantly higher after asphyxia and it appeared to be a correlation between the levels of the biomarkers and the severity of the insult.

Discussion: Future studies are warranted to support or refute the value of Tau/NFLin clinical practice.

Conclusion: Fetal asphyxia remains a clinical problem resulting in life-long neurological disabilities. We urgently need more accurate early predictive markers to direct the clinician when to provide neuroprotective therapy.     

Maternal burn-out: an exploratory study

Introduction: Maternal burn-out is a psychological, emotional and physiological condition resulting from the accumulation of various stressors characterised by a moderate but also a chronic and repetitive dimension. Little research has focused on this syndrome.

Objective: The current study aims to assess maternal burn-out rate and to identify factors associated with this state of exhaustion.

Method: 263 French mothers aged between 20 and 49 years answered five scales quantifying maternal burn-out, perceived social support, parental stress, depression and anxiety symptoms and history of postnatal depression.

Results: About 20% of mothers were affected by maternal burn-out. The main factors related to maternal burn-out were having a child perceived as difficult, history of postnatal depression, anxiety, satisfaction of a balance between professional and personal life and parental stress.

Conclusion: This research shows the need for further work on maternal burn-out to better understand and prevent this syndrome.     

Support for family diversity: a three-country study

Objective: To understand levels of support for differences between families in terms of sexuality and mode of family formation across three countries.

Background: Previous research has found that attitudes towards family diversity continue to improve over time, although differences remain.

Methods: Subjects were 1605 people living in Australia, the United Kingdom or the United States who completed a questionnaire which sought to explore levels of support for a diverse range of family forms and modes of family formation.

Results: Religiosity, political leanings and beliefs about the importance of genetic relatedness were all correlated with level of support. Gender of participant was a predictor of level of support. Cluster analysis indicated three clusters (unsupportive, neutral and supportive) for level of support, for which both sexuality and parent status were predictors.

Conclusion: Findings highlight the normative status of reproductive heterosex, and demonstrate the considerable value accorded to genetic relatedness.     

Influence of storage time on vitrified human cleavage-stage embryos froze in open system

Background: During in vitro fertilization, rapid growth of vitrification and liquid nitrogen storage of embryos have been well characterized. However, the effect of storage time on vitrified cleavage-stage embryos in an open system is poorly understood.

Aims: To investigate the influence of storage time on the survival and pregnancy outcomes of vitrified human cleavage-stage embryos froze and stored in an open system.

Methods: A retrospective study of 786 vitrified-warmed cycles of 735 patients was performed from January 2013 to October 2013. The cycles were divided into five groups according to storage time: 1–3 months, 4–6 months, 7–12 months, 13–24 and 25–60 months. The clinical outcomes of cycles with different storage time were analyzed.

Results: There were no significant differences of the survival rate, clinical pregnancy outcomes, birth rate, gestational weeks and singleton birthweights at various storage times.

Conclusion: For vitrified embryos froze and stored in an open system, the storage time would not influence the survival rate and pregnancy outcomes by storage time up to 5 years.     

Increased mood symptoms in postmenopausal women related to the polymorphism rs743572 of the CYP17 A1 gene

Background: Menopausal and depressive symptoms are highly prevalent after the menopause; but may vary from one population to another and genetics play a key role.

Objective: To analyze the intensity of these symptoms in relation to the genetic variants of the rs743572 polymorphism of the CYP17 A1 gene in postmenopausal women.

Methods: DNA was extracted from the whole blood of 168 natural postmenopausal women (40–65 years) and tested for the rs743572 polymorphism of the CYP17 A1 gene. Intensity of menopausal (Menopause Rating Scale, MRS) and depressive symptoms (Hospital Anxiety and Depressive Scale, HADS) were correlated to polymorphism genotypes.

Results: Women with the GG genotype of the rs743572 polymorphism displayed significantly higher scores for the MRS (items 5 and 6 [irritability and anxiety] and the psychological subscale) and the HADS (total and subscales).

Conclusion: The intensity of menopausal symptoms related to mood was found higher among postmenopausal women presenting the GG genotype of the rs743572 polymorphism of the CYP17 A1 gene. There is a need for more research in this regard.     

Anti-Mullerian hormone and insulin resistance in polycystic ovary syndrome

Introduction: Polycystic ovary syndrome (PCOS) is a prevalent disease affecting women of reproductive age. It may be associated with metabolic disorders such as insulin resistance (IR) and obesity. The anti-Mullerian hormone (AMH) levels seem to be higher in patients with PCOS.

Objective: The present study was designed to evaluate the association between AMH and insulin in women with PCOS with and without IR.

Methods: Cross-sectional study, including 86 patients, selected and divided into three groups: Group A: 26 women with PCOS and IR; Group B: 30 women with PCOS and without IR; and Group C: 30 controls without PCOS.

Results: We found significant difference between serum AMH levels in the group of women with PCOS and without IR when compared to the control group, thus showing that PCOS and IR play an important role in elevating the levels of this hormone. When the groups were compared with each other following adjustment for BMI, serum AMH levels were significantly higher in the group of women with PCOS and IR.

Conclusion: AMH levels are significantly higher in patients with PCOS, particularly in those women with PCOS and IR. Nevertheless, larger samples are required to confirm these findings.     

We wanted to choose us: how embryo donors choose recipients for their surplus embryos

Objective: This study aimed to explore factors affecting donors’ choice of recipients for their surplus embryos in the New Zealand context of conditional, known donations.

Background: Internationally, embryo donation has a low uptake in spite of large numbers of cryopreserved embryos. Possible reasons include a lack of knowledge about and concern for the future welfare of the resultant offspring. In New Zealand, donors and recipients meet prior to donation and legislation supports disclosure and access to genetic knowledge.

Method: Twenty-two embryo donors (10 couples, two individuals) were interviewed between March 2012 and February 2013 about their experiences of donation and factors affecting their donation. Interview data were analysed thematically.

Results: In the interests of the welfare of the child resulting from donation, donors were invested in choosing recipients who would make suitable parents. They attempted to choose recipients similar to themselves, as well as those that they trusted to disclose the manner of conception and facilitate agreed-upon information exchange and contact.

Conclusion: The interest of donors in ensuring offspring well-being may lend support to conditional forms of open donation, allowing for assessment of recipients’ suitability to parent, and for negotiation around information exchange and contact.     

The role of narrative medicine in pregnancy after liver transplantation

Narrative medicine allows professionals from all fields of medical sciences to understand the patient’s total experience of illness, and meet his/her needs in an empathetic environment. Narrative medicine helps spread holistic knowledge of a multitude of complex clinical conditions, including transplantation.

Objective: To underline the role of narrative medicine in women who become pregnant after a liver transplant by using their narrations of this very special experience.

Methods: We describe our study with narration and listening to the stories of three women expecting their first child after a liver transplant, by analysing the structure and role of narration in the context of relationships between patients and caregivers. The narrations were transcribed verbatim with the main plot analysed in order to address all the aspects of this rare clinical condition and the transition to parenthood.

Results: The women narrated this experience in three phases: transplantation, pregnancy and delivery, and post-partum. They described all phases of pregnancy as stressful but satisfying, whereas the fact of becoming a mother was perceived as a victory both as a woman and as a transplant patient.

Conclusions: Our results suggest that narrative medicine represents a significant professional tool for caring for transplant patients during pregnancy.     

Umbilical cord care: national survey,literature review and recommendations

Background: The basic principle of umbilical cord (UC) care is to keep it clean and dry, as this provides the fastest and safest UC healing.

Objective: To evaluate Slovenian UC care practice and compare its consistency with current international recommendations.

Methods: A questionnaire covering UC care from birth to complete healing of the umbilical wound was sent to all Slovenian primary-, secondary- and tertiary-level pediatric centers. Three different clinical conditions of the newborn’s umbilicus were defined: healthy umbilicus (HU), umbilicus at risk (UR) and unhealthy umbilicus (UU).

Results: The study revealed a correlation between the clinical condition of the umbilicus, the frequency of UC care and the antiseptic usage in both the outpatient and inpatient UC care groups. HU was treated less frequently than UR and significantly less than UU. In both groups, these two conditions were also indications for UC care with antiseptic. The frequency of antiseptic usage for HU care was significantly lower in the outpatient care group.

Conclusions: Slovenian UC care follows the general international recommendations. Based on these and our experience, we formulated recommendations for adjustments to UC care, depending on the clinical condition of the umbilicus, in order to prevent important complications.
