RESUMO

The third stage of labor is defined as the time period between delivery of the fetus through delivery of the placenta. During a normal third stage, uterine contractions lead to separation and expulsion of the placenta from the uterus. Postpartum hemorrhage is a relatively common complication of the third stage of labor. Strategies have been studied to mitigate the risk of postpartum hemorrhage, leading to the widespread implementation of active management of the third stage of labor. Initially, active management of the third stage of labor consisted of a bundle of interventions including administration of a uterotonic agent, early cord clamping, controlled cord traction, and external uterine massage. However, the effectiveness of these interventions as a bundle has been questioned, leading to abandonment of some components in recent years. Despite this, upon review of selected international guidelines, we found that the term "active management of the third stage of labor" was still used, but recommendations for and against individual interventions were variable and not necessarily supported by current evidence. In this review, we: (1) examine the physiology of the third stage of labor, (2) present evidence related to interventions that prevent postpartum hemorrhage and promote maternal and neonatal health, (3) review current global guidelines and recommendations for practice, and (4) propose future areas of investigation. The interventions in this review include pharmacologic agents to prevent postpartum hemorrhage, cord clamping, cord milking, cord traction, cord drainage, early skin-to-skin contact, and nipple stimulation. Treatment of complications of the third stage of labor is outside of the scope of this review. We conclude that current evidence supports the use of effective pharmacologic postpartum hemorrhage prophylaxis, delayed cord clamping, early skin-to-skin contact, and controlled cord traction at delivery when feasible. The most effective uterotonic regimens for preventing postpartum hemorrhage after vaginal delivery include oxytocin plus ergometrine; oxytocin plus misoprostol; or carbetocin. After cesarean delivery, carbetocin or oxytocin as a bolus are the most effective regimens. There is inconsistent evidence regarding the use of tranexamic acid in addition to a uterotonic compared with a uterotonic alone for postpartum hemorrhage prevention after all deliveries. Because of differences in patient comorbidities, costs, and availability of resources and staff, decisions to use specific prevention strategies are dependent on patient- and system-level factors. We recommend that the term "active management of the third stage of labor" as a combined intervention no longer be used. Instead, we recommend that "third stage care" be adopted, which promotes the implementation of evidence-based interventions that incorporate practices that are safe and beneficial for both the woman and neonate.

RESUMO

We present the case of a 30-year-old female with primary infertility who had multiple large myomas up to 22 weeks uterine size. She had a body mass index of 42 kg/m2 and also concurrent endometriosis, for which she was on medical management. After meticulous preoperative planning, total robotic myomectomy and endometriosis clearance was done. Four large myomas weighing a total of 750 g were removed after morcellation. Console time was 160 min, and she made an uneventful recovery with only 0.1 g/dL drop in hemoglobin. Robotic myomectomy is considered as an improvement over laparotomy for patients with up to three myomas and when the surgical time does not exceed 4 hours. We were successful in our attempt at total robotic myomectomy to extend these limits and had a positive surgical outcome.

RESUMO

Associations between anaesthetic techniques and pregnancy outcomes were assessed among 129,742 pregnancies delivered by caesarean section (CS) in low- and middle-income countries (LMICs) using two WHO databases. Anaesthesia was categorized as general anaesthesia (GA) and neuraxial anaesthesia (NA). Outcomes included maternal death (MD), maternal near miss (MNM), severe maternal outcome (SMO), intensive care unit (ICU) admission, early neonatal death (END), neonatal near miss (NNM), severe neonatal outcome (SNO), Apgar score <7 at 5 minutes, and neonatal ICU (NICU) admission. A two-stage approach of individual participant data meta-analysis was used to combine the results. Adjusted odds ratio (OR) with 95% confidence intervals (CIs) were presented. Compared to GA, NA were associated with decreased odds of MD (pooled OR 0.28; 95% CI 0.10, 0.78), MNM (pooled OR 0.25; 95% CI 0.21, 0.31), SMO (pooled OR 0.24; 95% CI 0.20,0.28), ICU admission (pooled OR 0.17; 95% CI 0.13, 0.22), NNM (pooled OR 0.63; 95% CI 0.55, 0.73), SNO (pooled OR 0.55; 95% CI 0.48, 0.63), Apgar score <7 at 5 minutes (pooled OR 0.35; 95% CI 0.29, 0.43), and NICU admission (pooled OR 0.53; 95% CI 0.45, 0.62). NA therefore was associated with decreased odds of adverse pregnancy outcomes in LMICs.

RESUMO

ABSTRACT: The molecular mechanism of iron transfer across placenta in response to maternal anemic status/ iron supplementation is not clear. We hypothesized that maternal iron/ anemia status during early trimesters can be utilized as a biomarker tool to get estimates of placental iron status. Early interventions can be envisaged to maintain optimum placental/ foetal iron levels for healthy pregnancy outcomes. One hundred twenty primigravida were recruited and divided into non-anemic and anemic group on the basis of hemoglobin levels. The groups were randomly allocated to receive daily and weekly iron folic acid (IFA) tablets till six weeks postpartum. Hematological and iron status markers in blood and placenta were studied along with the delivery notes. Weekly IFA supplementation in anemic primigravidas resulted in significantly reduced levels of hematological markers (p < 0.01); whereas non-anemic primigravidas showed lower ferritin and iron levels, and higher soluble transferrin receptor levels (p < 0.05). At baseline, C-reactive protein and cortisol hormone levels were also significantly lower in non-anemic primigravidas (p < 0.05). A significantly decreased placental ferritin expression (p < 0.05); and an increased placental transferrin expression was seen in anemic primigravidas supplemented with weekly IFA tablets. A significant positive correlation was observed between serum and placental ferritin expression in anemic pregnant women (r = 0.80; p < 0.007). Infant weight, gestational length and placental weight were comparable in both the supplementation groups. To conclude, mother's serum iron / anemia status switches the modulation in placental iron transporter expression for delivering the optimum iron to the foetus for healthy pregnancy outcomes.

RESUMO

Background Pregnancy is associated with biochemical changes leading to increased nutritional demands for the developing fetus that result in altered micronutrient status. The Indian dietary pattern is highly diversified and the data about dietary intake patterns, blood micronutrient profiles and their relation to low birthweight (LBW) is scarce. Methods Healthy pregnant women (HPW) were enrolled and followed-up to their assess dietary intake of nutrients, micronutrient profiles and birthweight using a dietary recall method, serum analysis and infant weight measurements, respectively. Results At enrolment, more than 90% of HPW had a dietary intake below the recommended dietary allowance (RDA). A significant change in the dietary intake pattern of energy, protein, fat, vitamin A and vitamin C (P < 0.001) was seen except for iron (Fe) [chi-squared (χ2) = 3.16, P = 0.177]. Zinc (Zn) deficiency, magnesium deficiency (MgDef) and anemia ranged between 54-67%, 18-43% and 33-93% which was aggravated at each follow-up visit (P ≤ 0.05). MgDef was significantly associated with LBW [odds ratio (OR): 4.21; P = 0.01] and the risk exacerbate with the persistence of deficiency along with gestation (OR: 7.34; P = 0.04). Pre-delivery (OR: 0.57; P = 0.04) and postpartum (OR: 0.37; P = 0.05) anemia, and a vitamin A-deficient diet (OR: 3.78; P = 0.04) were significantly associated with LBW. LBW risk was much higher in women consuming a vitamin A-deficient diet throughout gestation compared to vitamin A-sufficient dietary intake (OR: 10.00; P = 0.05). Conclusion The studied population had a dietary intake well below the RDA. MgDef, anemia and a vitamin A-deficient diet were found to be associated with an increased likelihood of LBW. Nutrient enrichment strategies should be used to combat prevalent micronutrient deficiencies and LBW.

RESUMO

BACKGROUND: Anaemia affects as many as half of all pregnant women in low-income and middle-income countries, but the burden of disease and associated maternal mortality are not robustly quantified. We aimed to assess the association between severe anaemia and maternal death with data from the WHO Multicountry Survey on maternal and newborn health. METHODS: We used multilevel and propensity score regression analyses to establish the relation between severe anaemia and maternal death in 359 health facilities in 29 countries across Latin America, Africa, the Western Pacific, eastern Mediterranean, and southeast Asia. Severe anaemia was defined as antenatal or postnatal haemoglobin concentrations of less than 70 g/L in a blood sample obtained before death. Maternal death was defined as death any time after admission until the seventh day post partum or discharge. In regression analyses, we adjusted for post-partum haemorrhage, general anaesthesia, admission to intensive care, sepsis, pre-eclampsia or eclampsia, thrombocytopenia, shock, massive transfusion, severe oliguria, failure to form clots, and severe acidosis as confounding variables. These variables were used to develop the propensity score. FINDINGS: 312 281 women admitted in labour or with ectopic pregnancies were included in the adjusted multilevel logistic analysis, and 12 470 were included in the propensity score regression analysis. The adjusted odds ratio for maternal death in women with severe anaemia compared with those without severe anaemia was 2·36 (95% CI 1·60-3·48). In the propensity score analysis, severe anaemia was also associated with maternal death (adjusted odds ratio 1·86 [95% CI 1·39-2·49]). INTERPRETATION: Prevention and treatment of anaemia during pregnancy and post partum should remain a global public health and research priority. FUNDING: Barts and the London Charity.

RESUMO

BACKGROUND: The World Health Organization (WHO) recommends induction of labour (IOL) for women who have reached 41 completed weeks of pregnancy without spontaneous onset of labour. Many women with prolonged pregnancy and/or their clinicians elect not to induce, and chose either elective caesarean section (ECS) or expectant management (EM). This study intended to assess pregnancy outcomes of IOL, ECS and EM at and beyond 41 completed weeks. METHODS: This study is a secondary analysis of the WHO Global Survey (WHOGS) and the WHO Multi-country Survey (WHOMCS) conducted in Africa, Asia, Latin America and the Middle East. There were 33,003 women with low risk singleton pregnancies at ≥41 completed weeks from 292 facilities in 21 countries. Multilevel logistic regression model was used to assess associations of different management groups with each pregnancy outcome accounted for hierarchical survey design. The results were presented by adjusted odds ratios (aORs) with 95% confidence intervals (CIs) after adjusting for age, education, marital status, parity, previous caesarean section (CS), birth weight, and facility capacity index score. RESULTS: The prevalence of prolonged pregnancy at facility setting in WHOGS, WHOMCS and combined databases were 7.9%, 7.5% and 7.7% respectively. Regarding to maternal adverse outcomes, EM was significantly associated with decreased risk of CS rate consistently in both databases i.e. (aOR0.76; 95% CI: 0.66-0.87) in WHOGS, (aOR0.67; 95% CI: 0.59-0.76) in WHOMCS and (aOR0.70; 95% CI: 0.64-0.77) in combined database, compared to IOL. Regarding the adverse perinatal outcomes, ECS was significantly associated with increased risks of neonatal intensive care unit admission (aOR1.76; 95% CI: 1.28-2.42) in WHOMCS and (aOR1.51; 95% CI: 1.19-1.92) in combined database compared to IOL but not significant in WHOGS database. CONCLUSIONS: Compared to IOL, ECS significantly increased risk of NICU admission while EM was significantly associated with decreased risk of CS. ECS should not be recommended for women at 41 completed weeks of pregnancy. However, the choice between IOL and EM should be cautiously considered since the available evidences are still quite limited.

RESUMO

AIMS: Pregnancy is a phenomenon associated with dynamic changes in physical, mental and biochemical status of body and demands increased nutritional intake for developing foetus. The level of various micronutrients which act as co-factors for antioxidant enzymes or it-self as antioxidants gets altered with the progression of pregnancy. The present longitudinal study summarized the trend of selected micronutrients level in anaemic (AP) and non-anaemic primigravida (NAP) supplemented with daily and weekly oral iron folic acid (IFA) tablet during pregnancy and postpartum. METHODS: A total of 200 primigravida {N = 100; NAP (Hb > 11 g/dl) and N = 100 AP (Hb = 8-11 g/dl) assigned daily (N = 50) and weekly (N = 50) supplementation} were recruited and overnight fasting blood samples were withdrawn at 13-16 weeks, after 3 months and 6 weeks postpartum. The serum iron, copper, zinc, magnesium and manganese were estimated by inductively coupled plasma-atomic emission spectrophotometer. RESULTS: Serum manganese (p < 0.05) at baseline and magnesium (p < 0.01) at postpartum was significantly different between NAP and AP supplemented with daily IFA tablets. The trend of copper found to be increased during pregnancy and later declined at postpartum in both the groups. Daily supplementation resulted in significantly high iron (p < 0.05) in NAP during third trimester. CONCLUSIONS: Hypozincemia and hypomagnesemia was observed in anaemic pregnancy supplemented with weekly and daily IFA respectively. Clear evidence of altered micronutrients levels during healthy and anaemic pregnancy was seen. The reference values may be drawn from this study for the nutritional assessment during pregnancy for healthy pregnancy outcomes.

RESUMO

INTRODUCTION: In high-income countries, a reduced clinical threshold for obstetric interventions such as labour induction (LI) and prelabour caesarean delivery (PLCD) has played a substantial role in increasing rates of late preterm births. However, the association between provider-initiated delivery and perinatal outcomes have not been studied in a multicountry setting including low-income and middle-income countries. METHODS: 286 hospitals in 29 countries participated in the WHO Multi-Country Survey on Maternal and Newborn Health and yielded 2 52 198 singleton births of at least 34 weeks in 2010-2011. We used an ecological analysis based on generalised estimating equations under multilevel logistic regression to estimate associations between hospital rates of PLCD and LI with rates of late preterm birth (34-36 weeks), stillbirth and intrahospital early neonatal death, in relation to country development based on the Human Development Index (HDI). RESULTS: Rates of LI were higher in hospitals from very high-HDI (median 10.9%) and high-HDI (11.2%) countries compared with medium-HDI (4.0%) or low-HDI (3.8%) countries. Rates of PLCD were by far the lowest in low-HDI countries compared with countries in the other three categories (5.1% vs 12.0%-17.9%). Higher rates of PLCD were associated with lower perinatal death rates (OR 0.87 (0.79, 0.95) per 5% increase in PLCD) and non-significantly with late preterm birth (1.04 (0.98, 1.10)) regardless of country development. LI rates were positively associated with late preterm birth (1.04 (1.01, 1.06)) regardless of country development and with perinatal death (1.06 (0.98, 1.15)) only in middle-HDI and low- HDI countries. CONCLUSION: PLCD was associated with reduced perinatal mortality and non-significantly with increased late preterm birth. LI was associated with increases in both late preterm birth and, in less-developed countries, perinatal mortality. Efforts to provide sufficient, but avoid excessive, access to provider-initiated delivery should be tailored to the local context.

RESUMO

Caesarean section (CS) is increasing globally, and women with prior CS are at higher risk of uterine rupture in subsequent pregnancies. However, little is known about the incidence, risk factors, and outcomes of uterine rupture in women with prior CS, especially in developing countries. To investigate this, we conducted a secondary analysis of the World Health Organization Multicountry Survey on Maternal and Newborn Health, which included data on delivery from 359 facilities in 29 countries. The incidence of uterine rupture among women with at least one prior CS was 0.5% (170/37,366), ranging from 0.2% in high-Human Development Index (HDI) countries to 1.0% in low-HDI countries. Factors significantly associated with uterine rupture included giving birth in medium- or low-HDI countries (adjusted odds ratio [AOR] 2.0 and 3.88, respectively), lower maternal educational level (≤6 years) (AOR 1.71), spontaneous onset of labour (AOR 1.62), and gestational age at birth <37 weeks (AOR 3.52). Women with uterine rupture had significantly higher risk of maternal death (AOR 4.45) and perinatal death (AOR 33.34). Women with prior CS, especially in resource-limited settings, are facing higher risk of uterine rupture and subsequent adverse outcomes. Further studies are needed for prevention/management strategies in these settings.

RESUMO

PURPOSE: To evaluate the role of umbilical cord serum (UCS) and autologous serum (AS) therapy in reepithelialization of corneal graft after keratoplasty in a randomized controlled trial. METHODS: A total of 105 eyes with epithelial defect (ED) after keratoplasty (penetrating keratoplasty-67 and anterior lamellar keratoplasty-38) on the first postoperative day were included in the study. The eyes were randomized into three groups: UCS (n=35), AS (n=35), and artificial tears (AT) (n=35). All patients received standard postoperative medical therapy. The primary outcome measure was time to epithelialization, and secondary outcome measures were best-corrected visual acuity and graft clarity. RESULTS: The ED healed completely in 103 eyes. The mean time for complete reepithelialization was 2.5±2.1, 3.1±2.2, and 4.5±1.4 days in UCS, AS, and AT groups, respectively. The mean percentage decrease in the size of the ED was significantly better in the UCS and AS groups as compared with the AT group (P=0.001). The rate of reepithelialization was comparable between the AS and UCS groups (P=0.3). On bivariate analysis, significant correlation was found between the mean size of postoperative ED, grade of the donor cornea (P=0.001), and the presence of preoperative ED (P=0.001). No complications were associated with the use of serum therapy. CONCLUSION: Most of the cases of postkeratoplasty corneal ED can be managed with AT only. The serum therapy (AS/UCS) helps in the faster reepithelialization of postkeratoplasty ED as compared with AT and may be considered as a treatment option for early epithelial healing.

RESUMO

Anaemia during pregnancy is most commonly observed and highly prevalent in South-East Asia. Various effective programmes have been laid down for its management, mainly daily supplementation of iron folic acid (IFA) tablets. Following the same, standard obstetrical practice has included the IFA supplementation without requiring the determination of iron deficiency. In this study, a total of 120 primigravida (N = 60; non-anaemic (Hb > 11 g/dl) and N = 60 anaemic (Hb = 8-11 g/dl)) were selected among those attending the Antenatal Clinic in Department of Obstetrics and Gynaecology, All India Institute of Medical Sciences, Ansari Nagar, New Delhi, India. They were supplemented with daily and weekly IFA tablets till 6 weeks postpartum. Corresponding changes in haemoglobin level on advance of pregnancy, side effects and compliance associated with daily and weekly IFA supplementation and its associations with iron status markers were studied. The inflammatory markers were also estimated. The statistical significance level (p < 0.05) between the groups were assessed by applying unpaired t-test using SPSS (version 16.0). The obtained results publicized the salutary role of daily IFA supplementation in improving the haemoglobin level and iron status markers in anaemic pregnant women though the levels could not reach up to the non-anaemic haemoglobin levels. However, weekly IFA supplementation seems to be a better approach in non-anaemic pregnant women where almost comparable results were obtained in terms of haematological parameters, gestation length and birth weight. CONCLUSION: Weekly IFA supplementation found to be as effective as daily supplementation in iron sufficient non-anaemic pregnant women whereas anaemic pregnant women should be prescribed daily IFA supplementation irrespective of iron replete/deplete state.

RESUMO

INTRODUCTION: Emergency contraception is a safe and effective method to prevent an unwanted pregnancy after an unprotected or inadequately protected sexual intercourse. Several methods for emergency contraception (EC) are currently registered in many countries for use in an emergency to prevent a pregnancy following an unprotected, possibly fertile intercourse or after a contraceptive accident like condom rupture. Different methods have varying modes of action, time frame of efficacy, dosage schedule and unwanted effects. Since several methods are available it is important to decide the best method. EVIDENCE ACQUISITION: In this article the available literature on emergency contraception has been reviewed and an attempt has been made to discuss the need for emergency contraception and compare different options for emergency contraception in terms of their efficacy in pregnancy prevention, their safety profile and unwanted side effects. EC repeated use and initiating a regular method after EC use are also discussed. EVIDENCE SYNTHESIS: Emergency contraceptive methods include copper Intra-uterine devices (IUD) and different types of pills like estrogen progestin combination pill (Yuzpe Regimen), Progestin only pill (LNG), antiprogestin pill (Mifepristone), and progesterone modulator Uripristal Acetate (UPA). There is a marginal difference in the mechanism of action, efficacy including time frame and ability to protect from pregnancy with regular doses in obese women, drug interactions and side effects. These are discussed in detail. CONCLUSIONS: Copper IUD is the most effective emergency contraceptive with advantage of providing continued contraception. However, it cannot be used universally due to lack of infrastructure and a trained provider as well as not being suitable option for women at risk of sexually transmitted infections. Amongst different pills LNG is more effective with fewer side effects than Yuzpe regimen. LNG and UPA are comparable with similar efficacy and side effect profile. UPA has a wider window of efficacy, in LNG efficacy declines after 72 hours. UPA is more suitable for obese women. Mifepristone is effective but is registered as EC pill only in few countries and use is limited as it is also used as an abortion pill. Yuzpe regimen is the least effective of all contraceptive pills as EC, and works only till 72 hours of unprotected sex, but is useful in places where dedicated methods are not available, as it is easily accessible. Any combined pill can be used in this regimen except triphasic pill.

RESUMO

OBJECTIVE: To investigate optimal timing of elective repeat caesarean section among low-risk pregnant women with prior caesarean section in a multicountry sample from largely low- and middle-income countries. DESIGN: Secondary analysis of a cross-sectional study. SETTING: Twenty-nine countries from the World Health Organization Multicountry Survey on Maternal and Newborn Health. POPULATION: 29,647 women with prior caesarean section and no pregnancy complications in their current pregnancy who delivered a term singleton (live birth and stillbirth) at gestational age 37-41 weeks by pre-labour caesarean section, intra-partum caesarean section, or vaginal birth following spontaneous onset of labour. METHODS: We compared the rate of short-term adverse maternal and newborn outcomes following pre-labour caesarean section at a given gestational age, to those following ongoing pregnancies beyond that gestational age. MAIN OUTCOME MEASURES: Severe maternal outcomes, neonatal morbidity, and intra-hospital early neonatal mortality. RESULTS: Odds of neonatal morbidity and intra-hospital early neonatal mortality were 0.48 (95% confidence interval [CI] 0.39-0.60) and 0.31 (95% CI 0.16-0.58) times lower for ongoing pregnancies compared to pre-labour caesarean section at 37 weeks. We did not find any significant change in the risk of severe maternal outcomes between pre-labour caesarean section at a given gestational age and ongoing pregnancies beyond that gestational age. CONCLUSIONS: Elective repeat caesarean section at 37 weeks had higher risk of neonatal morbidity and mortality compared to ongoing pregnancy, however risks at later gestational ages did not differ between groups.

RESUMO

We present here a report, based on data obtained from six selected North Indian hospitals, on variations in the number of human deliveries over the period from 1 October 2010 to 30 September 2011. We tried to identify whether there are any cycles exhibited by the data. We discover cyclicity over different months of the year and days of the week whereas cyclicity over different phases of the lunar cycle is not clearly established.

OBJECTIVE: This study was evaluated the role of perifollicular Doppler blood flow in predicting cycle response in women with and without genital tuberculosis (TB) undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. MATERIALS AND METHODS: This prospective observational study was performed on 254 women undergoing IVF for tubal factor infertility in the assisted reproductive unit. Perifollicular Doppler blood flows were assessed in dominant follicles >16 mm before oocyte recovery in patients with and without genital TB. RESULTS: A positive correlation was found between estradiol on the day of human chorionic gonadotropin (r = 0.15, P = 0.05), number of oocytes retrieved (r = 0.25, P = 0.001), MII (r = 0.24, P = 0.001), day 1 2PN (r = 0.16, P = 0.04), number of embryos (r = 0.16, P = 0.04) and blood flow in patients without genital TB. A trend of having poor ovarian blood flow was observed in patients with genital TB when compared with those without the disease (P > 0.001). CONCLUSION: In our study, the perifollicular blood flow (PFBF) provided a favorable prediction on the quantity of oocytes retrieved, MII, day 1 2PN and number of embryos but did not show any significant statistical difference in other outcome variables including fertilization or cleavage rate in women with or without genital TB undergoing IVF/ICSI cycles. Hence PFBF has the potential to be used as a simple and non-invasive surrogate marker of capillary blood flow around recruitable follicles to predict response to ovarian stimulation and cycle outcome.

RESUMO

AIM: The aim of this study was to assess the role of total serum estradiol on the day of injection HCG, estradiol per mature follicle, and estradiol per oocytes retrieved (OR) on clinical pregnancy rate (CPR) and oocyte/embryo quality in assisted reproduction. MATERIALS AND METHODS: A retrospective review of 342 in vitro fertilization cycles with normal ovarian reserve in women who underwent long GnRH agonist protocol was included. The outcomes assessed are number of OR, number of mature oocytes (MO), number of oocytes fertilized (FO), fertilization rate, number of embryos cleaved (EC), cleavage rate (CR), number of Grade I embryos (E), number of cryopreserved embryos (CPE), and CPR. The Estradiol/follicle ratio (E2/fol) was defined as estradiol level per mature follicle >14 mm in diameter. Estradiol/oocyte (E2/O) ratio was defined as estradiol level per OR. These two ratios were categorized by the 25th percentile into four groups. RESULTS: A positive correlation was seen between E2/fol and OR (r = .334, p value = .0001), MO (r = .335, p value = .0001), FO (r = .222, p value = .002), and CPE (r = .289, p value = .0001). Increased CPR was seen in Group C (E2/fol = 200-299.99) compared to Group A, B, and D (p value = .033). With E2/O ratio, negative correlation was seen between E2/O and OR (r = -.281, p value = .002), MO (r = -.296, p value = .008), FO (r = -.220, p value = .003), EC (r = -.211, p value = .004), Grade 1 embryo (r = -.216, p value = .001), and CPE (r = -.206, p value = .005). No difference in FR, CR, or CPR was seen. No difference was seen in CPR with total serum estradiol. CONCLUSIONS: In conclusion, serum estradiol is an important determinant of IVF success. While total serum estradiol does not exert any positive or negative influence on IVF outcome, estradiol per mature follicle and retrieved oocytes do have an impact. Pregnancy rate is better when E2/fol is between 200 and 299.99 pg/ml. Also, increasing serum E2/fol positively correlates with better oocytes and embryo quality. In contrast, E2/O negatively correlates with oocytes and embryo quality parameters.

RESUMO

Emergency contraception (EC) is a safe and effective method which is used to prevent unwanted pregnancy after unprotected sexual intercourse. Many of the unwanted pregnancies end in unsafe abortions. The search for an ideal contraceptive, which does not interfere with spontaneity or pleasure of the sexual act, yet effectively controls the fertility, is still continuing. Numerous contraceptive techniques are available, yet contraceptive coverage continues to be poor in India. Thus, even when not planning for a pregnancy, exposure to unprotected sex takes place often, necessitating the use of emergency contraception. This need may also arise due to failure of contraceptive method being used (condom rupture, diaphragm slippage, forgotten oral pills) or following sexual assault. Emergency contraception is an intervention that can prevent a large number of unwanted pregnancies resulting from failure of regular contraception or unplanned sexual activity, which in turn helps in reducing the maternal mortality and morbidity due to unsafe abortions. However, a concern has been expressed regarding repeated and indiscriminate usage of e-pill, currently the rational use of emergency contraception is being promoted as it is expected to make a significant dent in reducing the number of unwanted pregnancies and unsafe abortions. In fact, since the introduction of emergency contraception, the contribution of unsafe abortion towards maternal mortality has declined from 13 to 8 per cent.

RESUMO

BACKGROUND: We report the main findings of the WHO Multicountry Survey on Maternal and Newborn Health (WHOMCS), which aimed to assess the burden of complications related to pregnancy, the coverage of key maternal health interventions, and use of the maternal severity index (MSI) in a global network of health facilities. METHODS: In our cross-sectional study, we included women attending health facilities in Africa, Asia, Latin America, and the Middle East that dealt with at least 1000 childbirths per year and had the capacity to provide caesarean section. We obtained data from analysis of hospital records for all women giving birth and all women who had a severe maternal outcome (SMO; ie, maternal death or maternal near miss). We regarded coverage of key maternal health interventions as the proportion of the target population who received an indicated intervention (eg, the proportion of women with eclampsia who received magnesium sulphate). We used areas under the receiver operator characteristic curves (AUROC) with 95% CI to externally validate a previously reported MSI as an indicator of severity. We assessed the overall performance of care (ie, the ability to produce a positive effect on health outcomes) through standardised mortality ratios. RESULTS: From May 1, 2010, to Dec 31, 2011, we included 314,623 women attending 357 health facilities in 29 countries (2538 had a maternal near miss and 486 maternal deaths occurred). The mean period of data collection in each health facility was 89 days (SD 21). 23,015 (7.3%) women had potentially life-threatening disorders and 3024 (1.0%) developed an SMO. 808 (26.7%) women with an SMO had post-partum haemorrhage and 784 (25.9%) had pre-eclampsia or eclampsia. Cardiovascular, respiratory, and coagulation dysfunctions were the most frequent organ dysfunctions in women who had an SMO. Reported mortality in countries with a high or very high maternal mortality ratio was two-to-three-times higher than that expected for the assessed severity despite a high coverage of essential interventions. The MSI had good accuracy for maternal death prediction in women with markers of organ dysfunction (AUROC 0.826 [95% CI 0.802-0.851]). INTERPRETATION: High coverage of essential interventions did not imply reduced maternal mortality in the health-care facilities we studied. If substantial reductions in maternal mortality are to be achieved, universal coverage of life-saving interventions need to be matched with comprehensive emergency care and overall improvements in the quality of maternal health care. The MSI could be used to assess the performance of health facilities providing care to women with complications related to pregnancy.

RESUMO

INTRODUCTION: Diagnostic hysteroscopy is a vital tool and a gold standard to evaluate the uterine cavity. The aim of this study was to estimate the prevalence of unsuspected intrauterine abnormalities. MATERIALS AND METHODS: This cross-sectional study was done involving 870 asymptomatic, infertile women enrolled for IVF, who underwent a transvaginal ultrasound followed by office hysteroscopy. The presence of uterine cavity abnormalities was recorded. RESULTS: Transvaginal sonography revealed abnormal findings in 113 patients (12.9 %). Hysteroscopy confirmed the ultrasound findings in 76 (67.3 %) women with no obvious findings seen on hysteroscopy in 37 (32.7 %). Among the 757 women, who had a normal pelvic scan, abnormal findings were observed in 108 (14.2 %) on hysteroscopy, while the remaining 649 (85.7 %) patients had normal findings on hysteroscopy. Thus, a total of 184 (21.1 %) patients had confirmed abnormalities that required to be treated before performing IVF/ICSI. CONCLUSIONS: The present study highlights the relatively higher prevalence of intrauterine abnormalities in our patient population. Diagnosing and treating these abnormalities are imperative to improve the success of IVF treatment. Therefore, a routine diagnostic hysteroscopy in these patients becomes mandatory before proceeding with expensive procedures such as assisted reproduction.
