    ABSTRACT: We conducted a survey to explore levels of awareness and knowledge of HPV and cervical cancer in 170 female students and whether mode of data collection (online vs. paper) affected the results. 27% of women named HPV as a cause of cervical cancer with online respondents more likely to do so. 75% of women had heard of HPV. More online respondents had heard of HPV than paper respondents. 127 women reported having heard of HPV, with a mean knowledge score of 2.989 (SD = 1.599). Online respondents scored higher (3.57, SD = 1.316) than paper respondents (2.688, SD = 1.591). Knowledge and awareness of HPV and its link to cervical cancer appear to have increased which may be related to the HPV vaccination programme. However, there is still a considerable number of women with little to no knowledge of HPV. Online surveys may result in an inflated estimation of awareness and knowledge.

    ABSTRACT: The aim of the study was to assess serum total antioxidant capacity (TAC) and the impact of supplements on oxidative stress (OS) during pregnancy. Fifty volunteer pregnant women (21-40 years old), in the 12 ± 2 weeks' and 38 ± 2 weeks' gestation of pregnancy (study group), and 25 non-pregnant healthy women (control group) were enrolled. All pregnant women were divided into two age groups (A1: < 35 years and A2: ≥ 35 years) and four groups according to supplementation (B1: iron, B2: folic acid, B3: both and B4: none). Antioxidant activity was assayed using the TAC kit (Cayman Chemical Co.). Level of statistical significance was p < 0.05. Serum TAC values in all pregnant women in the first trimester were significantly lower, as compared with those of the control group. Levels of TAC increased significantly in the third trimester of pregnancy, especially with folic acid or no supplementation. In conclusion, pregnancy is associated with OS, which is promoted by the administration of iron supplementation.

    ABSTRACT: The aim of this study was to determine the location of the appendix at the third trimester of pregnancy as there are conflicting results in literature. Distances from the base of the appendix were measured intra-operatively to the anterior iliac spine (A), symphysis pubis (B) and the xyphoid process (C). The same measurements were taken from McBurney's point on the abdominal wall (A1, B1 and C1). In the allocated 21 pregnant and 18 non-pregnant women, distance A and B were 10.3 ± 0.9 cm and 18.3 ± 3.2 cm in pregnant and 6.7 ± 0.9 cm and 13.2 ± 0.9 cm in non-pregnant women (p < 0.001), respectively. Distance C was shorter in pregnant women (14.7 ± 2.5 cm vs. 23.8 ± 1.9, p < 0.001). Conversely, distance C1 was longer in pregnant women (30.3 ± 3.0 vs. 24.8 ± 5.1 cm, p = 0.004). This study provides evidence that the appendix moves cranially late in the course of the pregnancy. Therefore, McBurney's point cannot be used as a reference point to localise the appendix at the third trimester of pregnancy.

    ABSTRACT: This is a systematic review for evaluating failure rates (secondary hysterectomy or maternal mortality) and success rates (subsequent menstruation or pregnancy) following radiological or conservative surgical interventions for abnormally invasive placenta (AIP). Twelve cohort studies and 8 case series or case reports were included. The cumulative outcomes showed success rates of 159/177 (89.8) for arterial embolisation, a secondary hysterectomy in 20/177 (11.3%), a subsequent menstruation in 74/85 (87.1%) and a subsequent pregnancy in 3/10 (30%). Artery occlusion balloon presented a success rate of 33/42 (78.6%), and a secondary hysterectomy presented that of 8/42 (19%). Uterus-preserving surgery showed a success rate of 48/76 (63.2), a secondary hysterectomy in 23/76 (30%), maternal mortality in 2/54 (3.7%), a subsequent menstruation in 20/37 (81.1%) and a subsequent pregnancy in 21/27 (77.8%). This review indicates that different uterine-sparing radiological and surgical techniques may be effective in managing AIP in select patients.

    ABSTRACT: Prescription of postnatal thromboprophylaxis has increased with the Royal College of Obstetricians and Gynaecologists and the National Institute for Health and Care Excellence guidance. Our study of postnatal women meeting the criteria for thromboprophylaxis aimed to ascertain compliance with low-molecular-weight heparin and barriers to completion of a full course. Women were recruited from the antenatal clinic or postnatal wards. Those who agreed were contacted by telephone 14 days after delivery and asked about their compliance with and experience of thromboprophylaxis. 111 women were followed up. We found reported compliance with postnatal thromboprophylaxis to be high (83% taking the full course); most women self-injected (54%) but a significant number relied on family members (39%). Most would be prepared to take the course in a future pregnancy (94%); however, some felt that they needed more information. Reported compliance with postnatal thromboprophylaxis is high. This may be down to the motivation of the new mother, appropriate information giving and access to health care professionals for advice.

    ABSTRACT: Objective: Noninvasive and simple markers are needed for the prediction of preterm delivery in women at risk for preterm labour. The aim of this study was to determine the value of platelet indices in the prediction of preterm delivery. Design: A retrospective study. Setting: Routine antenatal care in Zonguldak Bülent Ecevit University between 2008 and 2011. Sample: Ninety patients who delivered between 28 and 37 weeks of gestational age and 128 patients who delivered at term. Methods: Plateletcrit and other haematological markers, cervical dilatation and effacement, and the neutrophil-to-lymphocyte ratio as an inflammation marker. Main outcome measure: The role of platelet indices in predicting the preterm delivery. Results: The platelet count, plateletcrit, white blood cell count, red cell distribution width, and neutrophil count were significantly higher in the preterm delivery group. Receiver operating characteristic curve analysis showed that the plateletcrit cut-off value for predicting spontaneous preterm labour was 0.201%, with a sensitivity of 95.6% and specificity of 87.5%; the cut-off value for the platelet count was 234 ? 103/mm3 with a sensitivity of 81.0% and specificity of 71.0%. Conclusion: Plateletcrit is a low-cost, widely available, and noninvasive marker that might be used for the prediction of preterm delivery in patients with a history of preterm labour.

    ABSTRACT: We assessed whether maternal height was associated with gestational age in a cohort of 294 children born at term. Increasing maternal height was associated with longer pregnancy duration (p = 0.002). Stratified analyses showed that the main effect on pregnancy length appears to occur among shorter mothers (<165 cm tall), whose pregnancies were ∼0.6 and ∼0.7 weeks shorter than pregnancies of mothers 165-170 cm (p = 0.0009) and >170 cm (p = 0.0002) tall, respectively. Further, children of shorter mothers were more likely to be born early term than those of average height (p = 0.021) and taller (p = 0.0003) mothers. Maternal stature is likely to be a contributing factor influencing long-term outcomes in the offspring via its effect on pregnancy length.

    ABSTRACT: There are circumstances in the management of thromboembolic events during pregnancy when anticoagulant therapy is either contraindicated or not advisable, such as when pulmonary embolism (PE) or deep venous thrombosis is diagnosed close to term, given the risk of bleeding during delivery. In these cases, the thromboembolic risk can be controlled using temporary inferior vena cava filters (T-IVCFs). We present the case of a pregnant woman with thrombophilia who remained at rest for eight weeks due to an amniotic prolapse and for whom the placement of a T-IVCF was decided at 32 weeks' gestation after anticoagulant therapy had failed. An emergency caesarean section was performed at 33 weeks' gestation due to placental abruption following the spontaneous onset of preterm labour. The risk of bleeding during delivery when high doses of heparin are used, and the risk of PE when the heparin dose is decreased, needs to be evaluated versus the risks related to T-IVCF placement procedure and, as such, a review of the published experience in this field is warranted. We have concluded that T-IVCFs can be a safe alternative treatment for pregnant women in whom anticoagulation therapy is either contraindicated or not advisable.

    ABSTRACT: Objective: Emesis Gravidarum (EG) is common medical condition in pregnancy with significant negatively effects on daily social life, physical and psychological health. In this study, relationship of social support, psychological distress and mood disorders on EG were investigated. Methods: The pregnant women with mild EG were accepted as control group and moderate and severe EG were accepted as patient group. All patients completed sociodemographic data collection form, Pregnancy-Unique Quantification of Emesis and Nausea scale (PUQE-24), Symptom Check List questionnaire (SCL-90 R), Spielberger state-trait anxiety inventory (STAI), Beck depression inventory (BDI) and Multidimensional Scale of Perceived Social Support (MSPSS). STAI, BDI, MSPSS and GSI (global symptom index) scores of the patients and control groups were compared. Results: Statistically significant differences were found between the patients and control group on STAI score, BDI score and GSI scores. No statistically significant were found between the patients and control group on MSPSS score. Conclusion: Social support does not prevent patients from EG. But, there is a clear relationship between EG and psychological distress. Thus, psychiatric evaluation should be done in patients with EG. Obstetricians should encourage their patients to have psychiatric support. Further studies on relationship of psychosocial factors and EG are needed.

    ABSTRACT: Women obtain information on epidural analgesia from various sources. For epidural for pain relief in labour this is provided by the anaesthetist as part of the consenting process. There is much discussion about the inadequacy of this consenting process; we report on women's knowledge, experience and recall of this process at a regional hospital with a 24-h epidural service. Fifty-four women were interviewed within 72 h of a vaginal birth. 91% of the women had acquired information from friends, relatives and antenatal classes. Lack of recall of benefits of epidural analgesia accounted for 26 (38%) and 25 (26%) of the responses, respectively. Similarly in terms of amount of pain relief they could expect, 13 (21%) could not remember and 13 (21%) thought that it may not work. We suggest use of varying methods of disseminating information and wider utilisation of anaesthetists in the antenatal educational programmes.

    ABSTRACT: Pelvic organ prolapse (POP) is a debilitating condition of unknown aetiology affecting > 50% of women over 40 years of age. In POP patients, the vaginal walls are weakened allowing descent of pelvic organs through the vagina. We sought to determine if sphingosine-1-phosphate (S1P) signalling, which regulates smooth muscle contractility and apoptosis via the RhoA/Rho-kinase (ROK) pathway, is altered in the vagina of women with POP. Utilising anterior vaginal wall specimens, we provide novel demonstration of the S1P pathway in this organ. Additionally, comparing specimens from women having pelvic reconstructive surgery for POP and control subjects, we reveal increases in mRNA expression of the three major mammalian S1P receptors (S1P1-S1P3), and RhoA and the ROK isoforms: ROKα and ROKβ in POP patients, which correlates with a decrease in elastic fibre assembly pathway constituents. Taken together, our data suggest the S1P/ROK pathway as a novel area for future POP research and potential therapeutic development.
