Dexamethasone versus placebo for prevention of nausea, vomiting and pain after open total abdominal hysterectomy.

Post-operative nausea and vomiting (PONV) is a disturbing issue. Dexamethasone has been suggested for the prevention of PONV. The aim of the present study was to evaluate the efficacy of dexamethasone as an anti-emetic and analgesic following total abdominal hysterectomy. The study was performed as a double blind, placebo-controlled randomised clinical trial on 102 women undergoing an open total abdominal hysterectomy. The intervention group received 8 mg dexamethasone 1 h before surgery, and the control group received a placebo. The total number of emesis episodes during the 24 h after surgery did not show significant difference between the two groups, however, the number of emesis episodes in hours 2 and 4 after the surgery were less in the intervention group, but not in hours 0, 6, 12 and 24. The nausea severity in hours 0, 2, 4, 6 and 12 after the surgery, was less in the intervention group. The severity of pain was not different between the two groups.IMPACT STATEMENTWhat is already known on this subject? Post-operative nausea and vomiting (PONV) is an important and disturbing issue. It is one of the most common problems following gynaecological surgeries including open total abdominal hysterectomy (TAH). Dexamethasone has been suggested as a prophylaxis for the prevention of PONV.What do the results of this study add? Dexamethasone 8 mg is effective for the prevention of late onset PONV (after 2 h of surgery) in the cases of open total abdominal hysterectomy. However, it has no effect on PONV immediately following surgery (hour 0) and pain.What are the implications of these findings for clinical practice and/or further research? Dexamethasone can be considered as an effective prophylaxis for PONV for the first 24 h after an open total abdominal hysterectomy, but it has limited effects on the management of early onset of PONV; between 0 and 2 h after surgery. Since the highest rates of emesis episodes and nausea severity are at this time, it is suggested to combine another rapid onset medication with dexamethasone. Also, dexamethasone, 8 mg, cannot be considered for pain relief after an open total abdominal hysterectomy. Higher amounts of dexamethasone should be evaluated for this purpose, in order to find appropriate dosages.

A qualitative assessment of the sexual-health education, training and service needs of young adults in Tehran.

BACKGROUND: Sexual Health and Relationships Education (SHRE) provides individuals with knowledge and skills to manage risky behaviors and take informed decisions to protect themselves against STIs, and unintended pregnancy. Only minimal SHRE is provided in Iranian schools and universities and previous research has highlighted needs and demands for improved SHRE and sexual services in Iran. This study explored young, Iranian adults' experience of, and need for sexual health education, sexual skills training and sexual healthcare services, as well their views on how to augment and improve existing provision. DESIGN AND METHODS: Semi-structured interviews were conducted with a sample of 25 young adults who lived in Tehran, Iran and had volunteered to participate in the study. Transcripts were analyzed using thematic analysis. RESULTS: Participants explained their needs and demands for sexual health education and sexual healthcare. They unanimously expressed their dissatisfaction with available SHRE and sexual health care provision. They highlighted barriers to gaining sexual health information and seeking advice and healthcare, including a lack of reliable resources, taboo and cultural barriers, lack of trust and protected confidentiality. This has resulted in ambiguities and misconceptions, including those regarding the cause and transmission of STIs and correct use of contraceptives. Participants recommended improvements, including holding mixed-gender extracurricular workshops with a comprehensive approach to sexual health and relationships education. CONCLUSIONS: There is a clear need and demand for provision of relevant and reliable sexual health and relationships education for young adults in Tehran. This should be addressed to empower young people to make informed choices and avoid risky sexual behavior.

Evaluating the efficacy of outpatient use of isosorbide mononitrate on cervical ripening in pregnant women with unfavourable cervix.

The aim of the present study was to evaluate the efficacy of outpatient administration of nitric oxide donor isosorbide mononitrate for cervical ripening. A randomised clinical trial was performed on term pregnant women with Bishop Score < 6. In the case group, Isosorbide-5-mononitrate capsule and in the control group, placebo was inserted in the posterior vaginal fornix for two consecutive days. The main outcomes were increases in Bishop Score after 48 hours of intervention, number of vaginal deliveries and interval from intervention to delivery.There was a significant increase of the mean Bishop score in the isosorbide group [3.57 ± 1.12 VS 1.54 ± 1.42 respectively (p = .001)]. The other outcome variables did not show a significant difference between the two groups except for headache which was significantly more in the case group. No cases of tachysystole were observed in the two groups. Additionally, haemoglobin levels after delivery did not show a significant difference between the two groups.Impact statement:What is already known on this subject? Cervical ripening in women with an unfavourable cervix and having an indication for induction of labour is an important issue in modern obstetrics. Different methods have been used for cervical ripening and induction of labour including mechanical (i.e. laminaria tents, Dilapan-S, foley catheter), medical (i.e. PGs) and supportive methods. There is no consensus on the best option for cervical ripeningWhat will the results of this study add to the current knowledge of this subject? Outpatient administration of nitric oxide could affect cervical ripening without a significant improvement in the duration of different stages of labour, intervention to delivery interval and number of vaginal deliveries.What are the implications of these findings for clinical practice and/or further research? Due to the contradictory results of various studies, more studies should be performed with greater sample size to evaluate nitric oxide donor isosorbide mononitrate effect on labour duration and reducing caesarean deliveries. Additional data is needed to assess the real impact of NO donors on different stages of labour and its implications.

Efficacy comparison of titrated oral solution of misoprostol and intravenous oxytocin on labour induction in women with full-term pregnancy.

A double-blind randomised trial was conducted on women with gestational age of 40-42 weeks of pregnancy and Bishop score of more than 5. The first group received oxytocin infusion and the second group received a titrated oral solution of misoprostol. Then, the two groups were compared by the primary outcome (the number of deliveries in the first 24 hours of intervention). The two groups did not have any significant difference in maternal and gestational age at the time of intervention, primary Bishop score, parity and neonatal weight. The number of deliveries in the first 24 hours was greater in the misoprostol group. Duration of onset of intervention to proper contractions was longer in the misoprostol group. However, the number of deliveries between 6-12 hours, 12-18 hours and 18-24 hours after induction was greater in the misoprostol group. The incidence of tachysystole and meconium was greater in the misoprostol group.Impact statementWhat is already known on this subject? Labour induction is widely used where the continuation of pregnancy might be dangerous for the mother or the baby. Of the various methods used for induction, misoprostol which is a prostaglandin E1 analogue has been reviewed more in recent years. Misoprostol has various routes of administration but in most studies only vaginal administration has been evaluated, leaving us with limited data about oral administration.What do the results of this study add? Oral misoprostol is a suitable method for labour induction and can be used as an alternative to oxytocin.What are the implications of these findings for clinical practice and/or further research? Misoprostol is not expensive, has a long shelf life, accessible in underdeveloped countries and rural areas and has several routes of administrations such as oral, sublingual and vaginal. Despite the fact that the oral route of misoprostol has a fast absorption and easier administration, there are relatively few studies assessing the the use of the oral route of misoprostol. Misoprostol is a suitable method for Labour induction and it has the potentials of being used as an alternative for oxytocin, however, the optimum dosages, the preferred route of administration, the maximum dose, the maximum time for administration, and maternal and neonatal safety should be studied more.

A comparison between induction of labor with 3 methods of titrated oral misoprostol, constant dose of oral misoprostol and Foley catheter with extra amniotic saline infusion (EASI), in women with unfavorable cervix.

Background: Different methods of cervical ripening and induction of labor have been used in the cases of unfavorable cervix with different levels of success, but no method has been found to be the best option. The purpose of the present study was to find the effects and side effects of three different methods of cervical ripening and induction of labor. These three methods were oral titrated misoprostol, constant dose of oral misoprostol and Foley catheter with extra-amniotic saline infusion. Methods: This clinical trial was performed on women with unfavorable cervix who had been admitted in Akbarabadi Teaching Hospital for induction of labor and had bishop score of less than six; between March 2014- March 2015. The eligible women were assigned into three groups. In titrated oral misoprostol group (n=33), titrated solution of misoprostol, and in oral misoprostol group (n=33), 50µg oral misoprostol every four hours and in Foley catheter group (n=50), Foley catheter with extra-amniotic saline infusion were administered. The main outcome was the number of vaginal deliveries during the first 24 hours. In addition, number of cesarean deliveries and adverse effects were compared between the three groups. The obtained data were analyzed using SPSS 18 software. Data analysis was performed according to the intention to treat principle. Chi-square test, Fisher Exact test, Student ttest, and Mann-Whitney U test, were used for comparing data. P-value≤0.05 was considered statistically significant. Results: The three groups did not have any significant difference according to maternal age, gestational age at the time of admission, gravidity, parity, and primary Bishop Score. There was no significant difference between the three groups for the main outcome, which was vaginal delivery during the first 24 hours (p=0.887). There was no significant difference between the three groups according to hypertonicity, uterine hyperstimulation, meconium passage, non-reassuring fetal heart rate, neonatal Apgar score in minutes one and 5, and mean duration of beginning the intervention up to delivery. However, uterine tachysystole and NICU admission were more in the group to whom the titrated solution of misoprostol was administered (p=0.002 and p=0.037 respectively). The number of cesarean deliveries due to failure to progress was higher in the EASI group. However, EASI group showed the least number of none-reassuring fetal heart rate between the three groups. Meconium passage was more in the titrated misoprostol group, but the difference was not significant. Conclusion: All three methods are appropriate methods for induction of labor in the cases of unfavorable cervix; and choosing each method depends on the expertise of labor staff, accessibility to the medications, cost, and taking care for monitoring the patients and adverse effects.

Evaluating the effects of administration of 25-hydroxyvitamin D supplement on serum anti-mullerian hormone (AMH) levels in infertile women.

The aim of the study was to evaluate the effects of administration of 25-hydroxyvitamin D [25(OH) D] on serum antimullerian hormone (AMH) levels in infertile women. The study was performed as a non-randomized clinical trial on 30 infertile women who had low serum level of both 25(OH) D and anti-mullerian hormone. Vitamin D was prescribed 50,000 IU weekly for up to three months for all eligible participants. Serum levels of both 25(OH) D and AMH have increased significantly after treatment with 25(OH) D. There was a significant correlation between serum levels of 25(OH) D after treatment with AMH (p = .029, OR = 2.9, CI 95% = 2.7-5.5). Mean AMH level after treatment was higher in women with sufficient 25(OH) D, than women with insufficient 25(OH) D (1.048 ± 0.644 vs. 0.513 ± 0.284 ng/ml), which shows a significant difference (p = .043). Also, after treatment, in women with mean AMH level of >0.7 ng/ml (19 women), mean level of 25(OH) D was higher than in women with mean AMH level of <0.7 ng/ml (11 women) (59.332 ± 21.751 vs. 38.881 ± 17.281 ng/ml, p = .013). This means that higher levels of 25(OH) D are accompanied with higher levels of AMH. In conclusions with administration and increasing the amount of vitamin D serum levels, the serum levels of AMH have increased.

Comparison between two doses of betamethasone administration with 12 hours vs. 24 hours intervals on prevention of respiratory distress syndrome: a randomised trial.

The purpose of the present study was to compare the effect of a two-dose administration of betamethasone with 12 hours interval vs. 24 hours interval on neonatal respiratory distress syndrome (RDS). The study was performed as a randomised clinical trial on 201 pregnant women with a gestational age of 26-34 weeks. In one group 12 mg of betamethasone every 12 hours for two doses and in the other group 12 mg of betamethasone every 24 hours for two doses were prescribed intramuscularly. There were no significant differences between the two groups according to maternal age, parity, gravidity, BMI, neonatal sex, need to surfactant, NICU admission, NICU stay, neonatal death, neonatal sepsis and Apgar score at minutes 1 and 5, but the gestational age at the beginning of the study and delivery receiving complete course of betamethasone and neonatal weight were lower in 24 hours group. RDS, necrotising enterocolitis, intra-ventricular haemorrhage and chorioamnionitis were more in the 24 hours' group. Multiple regression analysis showed that RDS and IVH (p = .022, RR = 0.07, CI95% 0.006-0.96 and p = .013; RR = 0.9, CI95% 0.1-0.89, respectively) were more in the 24 hours group and neonatal death (p = .034, RR = 4.7, CI95% 1.07-16.2) and NEC (p = 0.038, RR = 2.5, CI95% 1.7-3.7), were more in the 12 hours group. In conclusion, it seems that 12 hours interval betamethasone therapy may be considered as an alternative treatment in the case of preterm labour for acceleration of lung maturity; however, it is suggested that more studies should be performed on this issue and various morbidities. IMPACT STATEMENT What is already known on this subject: Administration of a single course of corticosteroids in all women with a gestational age of 24-34 weeks of pregnancy who are at risk for preterm labour and delivery has been recommended. The accepted regimen by National Institutes of Health (NIH) is an injection of betamethasone for two doses with 24 hours interval. What do the results of this study add: Twelve hours interval betamethasone therapy may be considered as an alternative treatment in the cases of preterm labour for acceleration of lung maturity. What are the implications of these findings for clinical practice and/or further research: Prescription of two doses (complete regimen) is more important than the interval between two doses for obtaining the maximum effect in a preterm birth.

Comparison between maternal and neonatal outcome of PPROM in the cases of amniotic fluid index (AFI) of more and less than 5 cm.

The study was performed on pregnant women with a gestational age of 26-32 weeks of pregnancy, who had been admitted to the hospital with a confirmed diagnosis of premature rupture of membranes. In all eligible women, ultrasounds were performed for the evaluation of amniotic fluid index. Then, the women were divided into two groups according to amniotic fluid index of ≥5 cm and <5 cm. These women were followed and monitored up to delivery. The women of the two groups did not have significant difference between them according to age, gestational age at the time of ruptured membrane, body mass index, gravidity, parity, gestational age at delivery and route of delivery. Maternal morbidities including chorioamnionitis, placental abruption, uterine atony after delivery and retention of placenta did not show significant difference between the two groups. There was no significant difference between the two groups' amniotic fluid index <5 cm and amniotic fluid index ≥5 cm, regarding neonatal morbidities, except for neonatal sepsis and neonatal death, which were higher in the amniotic fluid index <5 cm group [7(14.6%) versus 1(2.3%), p = .039, RR = 7.7 (95%CI 0.04-0.06) and 11(30.9%) versus 2(4.7%), p = .013, RR = 6.095 (95%CI = 1.26-29.31)]. In the subgroups of two categories of gestational ages of 260-296 and 300-346, neonatal morbidities were higher in the amniotic fluid index <5 cm group. The results suggest that amniotic fluid index <5 cm should be considered as a warning sign for predicting poor prognosis of pregnancy complicated by preterm premature rupture of membranes. Impact statement What is already known on this subject? In a retrospective study in 1993, the relationship between oligohydramnios (which was defined as the largest single packet of fluid less than 2 × 2 cm) at the time of hospital admission, and the outcome of mother, foetus and neonates in a gestational age of less than 35 weeks of pregnancy was evaluated. In the oligohydramnios group, chorioamnionitis and funistis were more common. Also, the mean gestational age at the time of delivery and neonatal weight was less than that of the normal amniotic fluid group. According to these results, it was concluded that a low amniotic fluid volume in the women with preterm premature rupture of membranes (PPROM) can be considered as a prognostic factor in the cases of conservative management of PPROM. In contrast, the other study, which was performed on a larger sample size (290 patients), could not show more cases of amnionitis in the cases of amniotic fluid index (AFI) of less than 5 cm; however, the latency period was shorter in comparison with AFI of more than 5 cm. What do the results of this study add? Chorioamnionitis, placental abruption and uterine atony after delivery, retention of placenta and route of delivery did not show a significant difference between the two groups. Respiratory distress syndrome (RDS), need of surfactant and intubation, intra ventricular haemorrhage (IVH) and duration of neonatal intensive care unit (NICU) admission did not show a significant difference between the two groups; however, the rate of neonatal sepsis and neonatal death were higher in the AFI <5 cm group. What are the implications of these findings for clinical practice and/or further research? The results suggest that AFI <5 cm should be considered as a warning sign for predicting poor prognosis of pregnancy complicated by PPROM.

Evening primrose oil and labour, is it effective? A randomised clinical trial.

The purpose of the present study was to evaluate the effects of evening primrose oil (EvPO) on the duration of pregnancy and labour. The study was performed as a triple blind placebo controlled randomised clinical trial on nulliparous low-risk women with a certain gestational age of 40 weeks of pregnancy and a Bishop score of less than 4. In the case group (EvPO group), EvPO capsules were administered, 1000 mg, twice daily, for 7 days, and in the control group, placebo was administered similarly. The women of the two groups were followed up to delivery. In total, 80 women finished the study (40 in each group). The women of the two groups did not have significant differences according to age, BMI, Bishop Score at the beginning of the study, gestational age at entering the study, employment status and education level, the number of capsules used and duration of using medications. There was no significant difference between the two groups according to gestational age at delivery, need for induction or augmentation of labour, duration of different stages of labour, neonatal weight and Apgar scores, and the indications for hospital admission. Impact statement What is already known on this subject? Evening primrose oil has been used for the treatment of systemic disorders, which are accompanied with chronic inflammation such as atopic dermatitis, rheumatoid arthritis and psoriasis. Also, it has been proposed for some women's health conditions including breast pain (mastalgia), symptoms of premenstrual syndrome and menopausal symptoms, cervical ripening and induction or augmentation of labour. What do the results of this study add? Evening primrose oil does not have any impact on Bishop Score and the duration of different stages of labour. What are the implications of these findings for clinical practice and/or further research? According to the present study and the other performed studies, there is not enough evidence confirming effectiveness of Evening primrose oil for cervical ripening and duration of labour. It is suggested that pending further data its usage should be limited to experimental RCTs and its use in clinical practice should be prevented. Also, different routes of administration and different dosages should be investigated.

A comparison between the effects of metformin and megestrol on simple endometrial hyperplasia.

INTRODUCTION: Endometrial hyperplasia is one of the most serious causes of severe abnormal bleeding and also can be a precursor of endometrial carcinoma. OBJECTIVE: The purpose of the present study was to compare the effects of metformin and megestrol on the endometrial hyperplasia. METHODS: The study was performed as a randomized clinical trial on 42 cases of histopathologically confirmed simple endometrial hyperplasia without atypia. The eligible women were randomly assigned into two groups. In metformin group, metformin was prescribed, 500 mg twice a day (1000 mg daily), for a duration of 4 weeks, and then, followed by 1500 mg daily, for 8 more weeks. In the megestrol group, megestrol was prescribed 40 mg daily for 12 weeks. At the end of the duration of the treatment, endometrial sampling was performed and the results were compared between the two groups. RESULTS: The women of the two groups did not have significant difference according to age, BMI and gravidity, parity and history of abortion. Overall, 18 women (81.8%) in metformin group and 12 women (60%) in the megestrol group had normal endometrial histology, after 12 weeks of treatment (p = 0.11). CONCLUSION: Metformin is comparable with megestrol for the treatment of simple endometrial hyperplasia.

A comparison between pregnancy outcome in women in 15 to 19 and 20 to 35 years age group.

Background: Pregnancy is one of the most important periods of a woman's life and is influenced by many different factors. For years, it was assumed that teenage pregnancy can cause poor pregnancy outcome. The purpose of this study was to compare some pregnancy complications between 2 groups of 15 to 19 and 20 to 35 year- old primigravida pregnant women Methods: This was a cross- sectional study conducted on the data sheets of primigravida women who delivered their babies in a teaching hospital. A total of 3040 eligible women entered the study; of them, 280 (9.3%) were in the 15 to 19 years age group and 2756 in the 20 to 35 years age group. The 2 groups were compared for preeclampsia, PROM, preterm birth, SGA, placental abruption, and placenta previa. A logistic regression model was used for data analysis. Results: The women of the 2 groups significantly differed in BMI and socioeconomic background. The rate of preeclampsia (p=0.008), PROM (p=0.002), and preterm delivery (p=0.001) were less in the 15 to 19 years age group. The rate of placental abruption, placenta previa, IUFD, and SGA was not significantly different between the 2 groups. After multivariate regression analysis, preeclampsia (adjusted odd ratio= 2.157; 95% CI= 1.38- 4.21) and preterm delivery (adjusted odd ratio= 2.443; 95% CI= 1.78- 5.13) were found to be higher in the 20 to 35 years group. Conclusion: The risk of poor pregnancy outcome is not higher in teenage pregnancies compared to pregnancies in the 20 to 35 years age group if confounding factors, including socioeconomic factors, are carefully controlled.

A comparison between the effects of metformin and N-acetyl cysteine (NAC) on some metabolic and endocrine characteristics of women with polycystic ovary syndrome.

OBJECTIVE: To compare N-acetyl cysteine (NAC) and metformin on polycystic ovary syndrome (PCOS). METHOD: Study was performed as a randomized double-blind clinical trial on women with diagnosis of PCOS without additional complications. In one group, oral NAC 600 mg, three times a day and in the other group, 500 mg oral metformin, three times a day were prescribed. Duration of treatment was 24 weeks, and after finishing this period of treatment, fasting blood glucose (FBS) and insulin, lipid profile and Homeostasis Model Assessment (HOMA) index were measured (all the blood samples were taken while fasting) and were compared in the two groups. RESULTS: Forty-six women in NAC group and 48 women in metformin group finished the study. The two groups did not show significant difference according to age, body mass index (BMI) of more than 30; mean BMI, AUB, FBS, fasting blood insulin, lipid profile and HOMA index before treatment. After 24 weeks of treatment; BMI >30 [17 (35.4%) versus 7 (15.2%), p = 0.033], mean BMI [(28.36 ± 2.27) versus (27.11 ± 3.55), p = 0.44], number of women with the complain of abnormal uterine bleeding (AUB) [24 (50%) versus 13 (28.3%), p = 0.037], FBS [(90.02 ± 6.24) versus (86.61 ± 7.81), p = 0.021], fasting insulin (10.40 ± 2.64 versus 8.89 ± 2.20, p = 0.004), HOMA Index (2.09 ± 0.69 versus 1.71 ± 0.45, p = 0.001), low density lipoprotein (LDL) (141.83 ± 26.98 versus 127.89 ± 28.70, p = 0.017) were less in NAC group. Triglyceride (TG) and total cholesterol did not show significant difference between the two groups after treatment. High-density lipoprotein (HDL) was higher in NAC group. CONCLUSION: NAC can improve lipid profile and fasting blood sugar (FBS) and fasting blood insulin better than metformin.

Risk factors in ectopic pregnancy and differences between adults and adolescents, is consanguinity important?

The aim of the study was to determine the risk factors of ectopic pregnancy (EP) and to compare them between women over and under 20 years of age. 308 cases of EP (case group) were compared with 616 cases of normal pregnancy. Smoking [Ad OR =5.7 (CI 95%=2.8-11.6), p < 0.001], previous EP [Ad OR= 11.4 (CI 95%=3-42.4), p = 0.000], previous STD [Ad OR =3.2 (CI 95%=2.1-4.9), p < 0.001], previous use of IUD [Ad OR =4.1 (CI 95%=2.1-8), p < 0.001], history of infertility [Ad OR= 1.8 (CI 95%=1.1-3), p = 0.01], previous caesarean delivery [Ad OR= 1.5 (CI 95%=1.1-2.3), p = 0.03] and consanguinity [Ad OR =2.2 (CI 95%=1.3-3.6), p = 0.002] were considered as risk factors for EP. Prior abortion [p = 0.000], prior STD [p = 0.004], previous caesarean delivery [p = 0.000] and consanguinity [p = 0.04] were more in the >20-year-old group. Negative Rh [p = 0.02], good economic status [p = 0.000] and prior STD [p = 0.03] were more common in Afghan women. However, previous caesarean delivery [p = 0.04] was more in Iranian women. Smoking, previous EP, history of STD, IUD, infertility, previous caesarean delivery and consanguinity are all risk factors for EP.

A comparison between serum levels of interleukin-6 and CA125 in patients with endometriosis and normal women.

BACKGROUND: The purpose of the present study was to compare the serum levels of IL6 and CA125 in women with and without endometriosis. They were also compared in mild, moderate and severe cases. METHODS: In this case-control study, CA125 and IL6 levels in 76 women with laparoscopic proven endometriosis were compared with 76 women without evidence of endometriosis. Sensitivity, specificity, positive (PPV) and negative (NPV) predictive values were then calculated for each test. RESULTS: Both groups did not show significant difference in their age, BMI, ESR and gravidity. Mean serum levels of IL-6 and CA125 were significantly higher in the case group (30.4±6.43 vs 13.9±3.17 Pg/ml and 62.6±10.69 vs 16.6±1.79 IU/ml respectively). Considering a cutoff point of 30 Pg/ml for IL-6, sensitivity, specifically, PPV and NPV value of 21.1%, 66.6%, 86.8% and 23.37% were obtained, respectively. Considering a cutoff point of 35 IU/ml for CA125, sensitivity, specifically, PPV and NPV were 44.76%, 94.73%, 89.47% and 63.15%, respectively. Area under the ROC curve was 0.69 for CA125 and 0.54 for IL6, which showed a low value for these tests. CONCLUSION: Although CA125 and IL-6 were higher than normal controls in endometriosis, area under the ROC curve, did not show significant any diagnostic value for these tests.

Evaluation of the relationship between Helicobacter Pylori infection and Hyperemesis Gravidarum.

BACKGROUND: Hyperemesis gravidarum (HEG) is one of the many problems during pregnancy; its etiology has not been clearly understood. Inflammatory factors like helicobacter pylori infection has been considered as a risk factor in some studies. The purpose of the present study is to find a relationship between Helicobacter Pylori (H.P) infection and hyperemesis gravidarum (HEG). METHODS: A case control study was performed on two groups of pregnant women who were in the first trimester of their pregnancies. Case group were pregnant women with hyperemesis gravidarum and control group were pregnant women with the same gestational age but without hyperemesis gravidarum. In both groups, IgG for H.P was measured and compared between the 2 groups. RESULTS: Totally, 175 pregnant women were evaluated; 78 women with HEG and 97 without. Both groups had no statistically significant difference according to age, gestational age, gravidity, and body mass index (BMI). 51 women out of 78 (65.4%) in HEG group and 43 women (44.3%) in the control group were IgG positive for HP, which showed a significant difference (p=0.005); OR= 2.37, CI 95%= 1.28-4.38. Also, mean serum level of IgG was higher in the HEG group (42.1 ± 3.75 VS 32.6 ± 3.65, p= 0.05). Between the different variables of age, gestational age, gravidity and HP infection, only HP infection was found as a risk factor for HEG using logistic regression model (p=0.011); OR= 2.522, CI 95%= 1.23-5.14. CONCLUSION: HP infection is higher in HEG cases and may be considered as its risk factor.

Effects of tranexamic acid on the amount of bleeding following vaginal delivery and its adverse effects: a double-blind placebo controlled randomized clinical trial.

INTRODUCTION: Postpartum hemorrhage (PPH) is the most important concern after delivery. Tranexamic acid (TXA), an anti-fibrinolytic agent, has been suggested for prevention and treatment of PPH. OBJECTIVE: The purpose of the present study was to find the effects of TXA on the amount of bleeding following vaginal delivery and its adverse effects. MATERIALS AND METHODS: The study was performed as a randomized double blind placebo controlled clinical trial on low risk pregnant women who delivered vaginally. The patients were randomly assigned into two groups. Women in the intervention group received 10 mg/kg infusion of TXA in 100 mL normal saline and the control group received one vial of distilled water (as placebo) in 100 mL normal saline. The primary outcome was amount of bleeding after delivery. The secondary outcomes were decreased in hemoglobin level, need for additional uterotonic agents and need for blood transfusion. All were evaluated 6 h after delivery and compared in the two groups. Participants were followed up to six weeks after delivery for any TXA side effects. RESULTS: Two hundred and seven women finished the study. There were no significant differences between the two groups in terms of demographic data and risk factors for bleeding. Mean blood loss and need to misoprostol was more in the control group (p=.033 and p=.000, respectively). Hemoglobin level was higher in the TXA group 6 h after delivery. None of the subjects needed blood transfusion, uterine balloon tamponade or emergency hysterectomy. Adverse effects were higher in the TXA group, however, there were no side effects between weeks 3 and 6 in both groups. There were no thromboembolic events during six weeks after delivery. CONCLUSIONS: Tranexamic acid can reduce the amount of bleeding after vaginal delivery in low risk women without having serious complications. Also, it may decrease the need for additional uterotonic agents. Trial registration number and registry website: IRCT20091023002624N22.

Comparing the efficacy of dilapan with extra-amniotic saline infusion and oral misoprostol for cervical ripening in term pregnancies.

INTRODUCTION: Labor induction is an important issue in modern obstetrics. One of the important factors for the success of induction of labor is the Bishop score of cervix. OBJECTIVE: The purpose of the present study was to evaluate and compare the efficacy of dilapan with extra-amniotic saline infusion and oral misoprostol for cervical ripening in term pregnancies. METHODS: This clinical trial study was performed on 120 nulliparous pregnant women with the Bishop score of less than 5. Group one, group two and group three received dilapan, extra amniotic saline infusion (EASI) and misoprostol respectively. All three groups were compared for duration from beginning of the intervention up to cervical ripening and Bishop Score of ≥7, duration of active phase and the second stage of labor, number of deliveries in the first 24 h, duration from beginning of the intervention up to delivery, rout of delivery as well as neonatal weight, neonatal Apgar score; hyper- stimulation, and need for oxytocin and oxytocin doses administered after 12 h of intervention. RESULTS: The number of deliveries in the first 24 h after intervention were not significantly different between the three groups. There was no significant difference between the three groups according to duration from beginning of the intervention up to cervical ripening and Bishop Score of ≥7, duration of active phase and the second stage of labor, duration from beginning of the intervention up to delivery, rout of delivery as well as neonatal weight, neonatal Apgar score; and hyperstimulation. The Bishop Score was higher in the misoprostol group 6 h after intervention [dilapan: 4.32 ± 1.38, EASI: 5.47 ± 1.28, and misoprostol: 6.72 ± 1.61 (p = .000)], Oxytocin requirement [dilapan: 38 (95%) women, EASI: 37 (92.50%) and misoprostol: 30 (75%) women, p = .013], and required dose [dilapan: 7543 ± 2465 miu/ml, EASI: 5758 ± 1615miu/ml and misoprostol: 4930 ± 2589miu/ml, p = .000] were lower in misoprostol group. CONCLUSION: Dilapan is an effective and safe method for cervical ripening in full term gestations. In cases where misoprostol and EASI cannot be used or are not desirable, dilapan can be used as an alternative.Trial registration number and registry website: IRCT20091023002624N25.

Evaluation of placental alpha microglobulin-1(PAMG1) accuracy for prediction of preterm delivery in women with the symptoms of spontaneous preterm labor; a comparison with cervical length and number of contractions.

INTRODUCTION: Since the capacity of tertiary centers is limited, identifying women with the risk of preterm delivery is crucial amongst women who refer to hospitals with threatened preterm labor. OBJECTIVE: The purpose of the present study was to evaluate the accuracy of the placental alpha microglobulin-1 (PAMG-1) test for identifying women who referred to hospitals with signs of spontaneous preterm labor and ultimately delivered within ≤48 h and ≤7 of testing and ≤37 weeks of gestation and its comparison with cervical length of <25 mm and number of contractions. MATERIALS AND METHODS: A prospective observational study was performed on women with the signs of spontaneous preterm labor. Placental alpha microglobulin-1 (PAMG-1) was evaluated in vaginal secretion. Cervical length (CL) and number of contractions were evaluated and recorded. The test to- spontaneous- delivery interval was documented. Sensitivity (SN), specificity (SP), accuracy rate of the PAMG-1, cervical length of <25 mm and number of contractions in prediction of spontaneous preterm delivery within ≤48 h, ≤7 days and preterm delivery (≤37 weeks of gestation) were calculated. RESULTS: One hundred eighty women finished the study. 44 women had positive PAMG-1 test and 58 women had cervical length of <25 mm. Women with a positive PAMG-1 were more likely to deliver within ≤48 h (p < .0001), ≤7 days (p < .0001), and before 37 weeks (p < .0001), compared to the women who had a negative test. For delivery within ≤48 h, ≤7 days and ≤37 weeks, specificity (SP) of the PAMG-1; was statistically higher than cervical length of <25 mm and contractions of 12-17/hr but not contractions of ≥18/hr. PAMG-1 showed a higher accuracy rate than cervical length of <25 mm, contractions of 12-17/hr and contractions of ≥18/hr for deliveries within ≤48 h (78.9, 55.3, 48.9, and 69.44%, respectively) and ≤7 days (76.1, 55.32, 55, and 65.56%, respectively). For deliveries before 37 weeks; the PAMG-1 test showed higher LR + than CL of <25 mm, contractions of 12-17/hr and contractions of ≥18/hr [10.24 (2.57-40.86), 2.01 (1.24-3.23), 1.30 (1.05-1.62), and 5.12 (1.24-21.11), respectively]. PPV for deliveries within ≤48 h and ≤7 days for PAMG-1 was greater than cervical length of <25 mm and number of contractions, however, NPV did not show a significant difference. CONCLUSION: PAMG-1 test showed a higher accuracy rate for prediction of delivery within ≤48 and ≤7 days in comparison with cervical length of <25 mm and number of contractions. Also, PAMG-1 test had a higher positive likelihood ratio for deliveries at ≤37 weeks. PPV for deliveries within ≤48 h and ≤7 days for PAMG-1 was greater than cervical length of <25 mm and number of contractions, however, NPV did not show a significant difference.

Severe maternal outcome in Afghan immigrant women: A study in Tehran, Iran.

OBJECTIVE: To evaluate the risk factors for severe maternal outcome (SMO) in Afghan immigrant women. METHODS: Women with potentially life-threatening conditions (PLTC) were selected. Then risk factors for those PLTC which led to SMO (maternal near-miss or maternal death) were evaluated. In addition, risk factors for those SMOs occurring on hospital admission or during the first 12 hours after admission to the hospital (SMO12) were evaluated. RESULTS: Parity ≥3 (adjusted odds ratio [aOR] 3.24, 95% confidence interval [CI] 1.62-6.50, P = 0.03), low literacy level in mother (aOR 2.99, 95% CI 1.16-5.01, P = 0.03), inadequate prenatal care (aOR 2.74, 95% CI 1.2-3.87, P = 0.01), multigravidity (gravidity ≥5: aOR 2.62, 95% CI 1.31-4.53, P = 0.03), lack of health insurance (aOR 2.52, 95% CI 1.25-4.02, P = 0.01), and low literacy level in husband (aOR = 1.49, 95% CI 1.15-2.9, P = 0.02) were the risk factors for SMO in women with PLTC. Inadequate prenatal care (aOR 4.2, 95% CI 2.05-8.25, P = 0.04), low literacy level in mother (aOR 3.38, 95% CI 1.32-6.65, P = 0.04), parity ≥3 (aOR 2.69, 95% CI 1.16-4.7, P = 0.04), and lack of health insurance (aOR 2.13, 95% CI 1.25-3.67, P = 0.03) were risk factors for SMO12. CONCLUSION: There was a higher rate of SMO and SMO12 cases among Afghan immigrant women.

Cerebroplacental ratio (CPR) and reduced fetal movement: predicting neonatal outcomes.

OBJECTIVE: The aim of this study was to evaluate the role of cerebroplacental ratio (CPR) in term pregnancies with reduced fetal movements (RFM) and appropriate for gestational age (AGA)fetuses to predict poor neonatal outcomes. METHODS: A prospective cohort study was performed on 150 singleton pregnancies with gestational age of 37-41 weeks and multiple episodes of RFM (case group) and 150 pregnancies within the same criteria only without RFM (control group). Both groups had appropriate for gestational age (AGA)fetuses. Umbilical artery (UA) and middle cerebral artery (MCA) pulsatility indices (PI) were measured, and MCA to UA ratio (CPR) was calculated. Doppler indices and neonatal outcomes were compared between the two groups. Independent prediction role of CPR MoM was evaluated through a binary logistic regression method. RESULTS: The RFM group had significantly higher UA- PI MoM (1.01 ± 0.19 versus 0.86 ± 0.05, p < .001), lower MCA MoM (1.28 ± 0.20 versus 1.40 ± 0.13, (p < .001)) and lower CPR MoM (0.98 ± 0.24 versus 1.23 ± 0.12, (p < .001)) compared to the control group. Mean umbilical artery pH was lower in the RFM group and the frequency of neonatal UA cord pH <7.2 was higher in the RFM group. In RFM group, CPR MoM showed a significant linear correlation with birth weight centiles (r = 0.244, p = .003), umbilical artery pH (r = 0.319, p < .001) and Apgar score at minute 1 (r = 0.332, p < .001). CPR MoM exhibited negative correlation with duration of NICU stay (r= -0.187, p = .022). No similar correlation was observed in the control group. In binary logistic regression analysis, CPR MoM was adjusted for the results of NST; and it was concluded that CPR MoM was the only significant predictor of Apgar score minute 1 = <7 (OR: 0.004; 95% CI: 0.0002-0.0673, p < .001), umbilical artery ph <7.2 (OR: 0.019; 95% CI: 0.00005-0.0423, p < .001) and NICU admission (OR: 0.116; 95% CI: 0.018-0.744, p = .023). In multivariate binary logistic regression analysis included parity, history of abortion and ART, AFI, BPP and CPR MoM; the AFI (OR: 0.976; 95% CI: 0.957-0.995, p = .014), BPP (OR: 0.306; 95% CI: 0.172-0.545, p < .001) and CPR MoM (OR: 0.00005 95% CI: 0.000003-0.00061, p < .001) were the significant predictor of RFM. Area under the curve in receiver operating characteristics (ROC) curve was calculated as 0.828 for CPR MoM as a predictor of RFM (SE: 0.024, p < .001), yielding sensitivity and specificity estimates of 80.0% and 65.0%, respectively, using an optimal cutoff level of = < 1.19. CONCLUSION: This study concluded that reduced fetal movement was significantly related to low CPR MOM. Also, it showed the independent role of CPR MoM for prediction of lower neonatal umbilical artery pH, lower Apgar score minute 1 and higher rate of NICU admission in AGA term fetuses without considering NST results. Also, AFI, BPP and CPR MoM are significant predictors of RFM.
