Introduction
This is the first of seven articles from a preterm birth and stillbirth report. Presented here is an overview of the burden, an assessment of the quality of current estimates, review of trends, and recommendations to improve data.Preterm birth
Few countries have reliable national preterm birth prevalence data. Globally, an estimated 13 million babies are born before 37 completed weeks of gestation annually. Rates are generally highest in low- and middle-income countries, and increasing in some middle- and high-income countries, particularly the Americas. Preterm birth is the leading direct cause of neonatal death (27%); more than one million preterm newborns die annually. Preterm birth is also the dominant risk factor for neonatal mortality, particularly for deaths due to infections. Long-term impairment is an increasing issue.Stillbirth
Stillbirths are currently not included in Millennium Development Goal tracking and remain invisible in global policies. For international comparisons, stillbirths include late fetal deaths weighing more than 1000g or occurring after 28 weeks gestation. Only about 2% of all stillbirths are counted through vital registration and global estimates are based on household surveys or modelling. Two global estimation exercises reached a similar estimate of around three million annually; 99% occur in low- and middle-income countries. One million stillbirths occur during birth. Global stillbirth cause-of-death estimates are impeded by multiple, complex classification systems.Recommendations to improve data
(1) increase the capture and quality of pregnancy outcome data through household surveys, the main data source for countries with 75% of the global burden; (2) increase compliance with standard definitions of gestational age and stillbirth in routine data collection systems; (3) strengthen existing data collection mechanisms—especially vital registration and facility data—by instituting a standard death certificate for stillbirth and neonatal death linked to revised International Classification of Diseases coding; (4) validate a simple, standardized classification system for stillbirth cause-of-death; and (5) improve systems and tools to capture acute morbidity and long-term impairment outcomes following preterm birth.Conclusion
Lack of adequate data hampers visibility, effective policies, and research. Immediate opportunities exist to improve data tracking and reduce the burden of preterm birth and stillbirth.2.

Introduction
Interventions directed toward mothers before and during pregnancy and childbirth may help reduce preterm births and stillbirths. Survival of preterm newborns may also be improved with interventions given during these times or soon after birth. This comprehensive review assesses existing interventions for low- and middle-income countries (LMICs).Methods
Approximately 2,000 intervention studies were systematically evaluated through December 31, 2008. They addressed preterm birth or low birth weight; stillbirth or perinatal mortality; and management of preterm newborns. Out of 82 identified interventions, 49 were relevant to LMICs and had reasonable amounts of evidence, and therefore selected for in-depth reviews. Each was classified and assessed by the quality of available evidence and its potential to treat or prevent preterm birth and stillbirth. Impacts on other maternal, fetal, newborn or child health outcomes were also considered. Assessments were based on an adaptation of the Grades of Recommendation Assessment, Development and Evaluation criteria.Results
Most interventions require additional research to improve the quality of evidence. Others had little evidence of benefit and should be discontinued. The following are supported by moderate- to high-quality evidence and strongly recommended for LMICs:? Two interventions prevent preterm births—smoking cessation and progesterone? Eight interventions prevent stillbirths—balanced protein energy supplementation, screening and treatment of syphilis, intermittant presumptive treatment for malaria during pregnancy, insecticide-treated mosquito nets, birth preparedness, emergency obstetric care, cesarean section for breech presentation, and elective induction for post-term delivery? Eleven interventions improve survival of preterm newborns—prophylactic steroids in preterm labor, antibiotics for PROM, vitamin K supplementation at delivery, case management of neonatal sepsis and pneumonia, delayed cord clamping, room air (vs. 100% oxygen) for resuscitation, hospital-based kangaroo mother care, early breastfeeding, thermal care, and surfactant therapy and application of continued distending pressure to the lungs for respiratory distress syndromeConclusion
The research paradigm for discovery science and intervention development must be balanced to address prevention as well as improve morbidity and mortality in all settings. This review also reveals significant gaps in current knowledge of interventions spanning the continuum of maternal and fetal outcomes, and the critical need to generate further high-quality evidence for promising interventions.3.
Introduction
Despite the substantial global burden of preterm and stillbirth, little attention has been given to the ethical considerations related to research and interventions in the global context. Ethical dilemmas surrounding reproductive decisions and the care of preterm newborns impact the delivery of interventions, and are not well understood in low-resource settings. Issues such as how to address the moral and cultural attitudes surrounding stillbirths, have cross-cutting implications for global visibility of the disease burden. This analysis identifies ethical issues impacting definitions, discovery, development, and delivery of effective interventions to decrease the global burden of preterm birth and stillbirth.Methods
This review is based on a comprehensive literature review; an ethical analysis of other articles within this global report; and discussions with GAPPS's Scientific Advisory Council, team of international investigators, and a community of international experts on maternal, newborn, and child health and bioethics from the 2009 International Conference on Prematurity and Stillbirth. The literature review includes articles in PubMed, Academic Search Complete (EBSCO), and Philosopher's Index with a range of 1995-2008.Results
Advancements in discovery science relating to preterm birth and stillbirth require careful consideration in the design and use of repositories containing maternal specimens and data. Equally important is the need to improve clinical translation from basic science research to delivery of interventions, and to ensure global needs inform discovery science agenda-setting. Ethical issues in the development of interventions include a need to balance immediate versus long-term impacts—such as caring for preterm newborns rather than preventing preterm births. The delivery of interventions must address: women's health disparities as determinants of preterm birth and stillbirth; improving measurements of impact on equity in coverage; balancing maternal and newborn outcomes in choosing interventions; and understanding the personal and cross-cultural experiences of preterm birth and stillbirth among women, families and communities.Conclusion
Efforts to improve visibility, funding, research and the successful delivery of interventions for preterm birth and stillbirth face a number of ethical concerns. Thoughtful input from those in health policy, bioethics and international research ethics helped shape an interdisciplinary global action agenda to prevent preterm birth and stillbirth.4.

Background
Efforts to achieve the Millennium Development Goals (MDGs) to improve maternal and child health can be accelerated by addressing preterm birth and stillbirth. However, most global health stakeholders are unaware of the inextricable connections of these adverse pregnancy outcomes to maternal, newborn and child health (MNCH). Improved visibility of preterm births and stillbirths will help fuel investments and strengthen commitments in the discovery, development and delivery of low-cost solutions globally. This article addresses potential barriers and opportunities to increasing global awareness and understanding.Methods
Qualitative research was conducted to analyze current knowledge, attitudes and commitments toward preterm birth and stillbirth; identify advocacy challenges; and learn more about examples of programs that successfully advocate for research and appropriate interventions. Forty-one individuals from 14 countries on six continents were interviewed. They included maternal, newborn, and child health advocates and implementers, United Nations agency representatives, policymakers, researchers, and private and government donors.Results
A common recognition of three advocacy challenges with regard to preterm birth and stillbirth emerged from these interviews: (1) lack of data about the magnitude and impact; (2) lack of awareness and understanding; and (3) lack of low-cost, effective and scalable interventions. Participants also identified advocacy opportunities. The first of these opportunities involves linking preterm birth and stillbirth to the MDGs, adding these outcomes to broader global health discussions and advocacy efforts, and presenting a united voice among advocates in the context of broader MNCH issues when addressing preterm birth and stillbirth. Another key opportunity is putting a human face to these tragedies—such as a parent who can speak to the personal impact on the family. Lastly, several interviewees suggested identifying and engaging champions to garner additional visibility and strengthen efforts. Ideal champions will work collaboratively with these and other maternal, newborn and child health issues. Conclusion: Advocacy efforts to add preterm births and stillbirths to broader MNCH goals, such as the MDGs, and to identify champions for these issues, will accelerate interdisciplinary efforts to reduce these adverse outcomes. The next article in this report presents an overview of related ethical considerations.5.

Background
Preterm birth and stillbirth are complex local and global health problems requiring an interdisciplinary approach and an international commitment. Stakeholders developed recommendations for a Global Action Agenda (GAA) at the 2009 International Conference on Prematurity and Stillbirth. The primary goal of this GAA is to forge a collaborative effort toward achieving common goals to prevent preterm birth and stillbirth, and to improve related maternal, newborn, and child health outcomes.Conference participants
GAPPS co-convened this four-day conference with the Bill & Melinda Gates Foundation, March of Dimes, PATH, Save the Children, UNICEF and the World Health Organization. Participants included about 200 leading international researchers, policymakers, health care practitioners and philanthropists. A near-final draft of this report was sent three weeks in advance to help co-chairs and participants prepare for workgroup discussions.Global Action Agenda
Twelve thematic workgroups, composed of interdisciplinary experts, made recommendations on short-, intermediate-, and long-term milestones, and success metrics. Recommendations are based on the following themes: (1) advance discovery of the magnitude, causes and innovative solutions; (2) promote development and delivery of low-cost, proven interventions; (3) improve advocacy efforts to increase awareness that preterm birth and stillbirth are leading contributors to the global health burden; (4) increase resources for research and implementation; and (5) consider ethical and social justice implications throughout all efforts.Summary
The conference provided an unprecedented opportunity for maternal, newborn and child health stakeholders to create a collaborative strategy for addressing preterm birth and stillbirth globally. Participants and others have already completed or launched work on key milestones identified in the GAA. Updates will be provided at www.gapps.org.6.
Purpose
This study aimed to investigate the association between periodontitis in pregnant women and adverse pregnancy outcomes by heeding confounding risk factors for preterm low birth weight infants.Methods
This study was reported according to The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement. A case–control study was conducted. Medical records of all pregnant women attending a prenatal care clinic were screened. Those between 21 and 34 years and gestational age of 28–32 weeks were initially enrolled in the study. The exclusion criteria were then applied: diabetes mellitus, genitourinary tract infections, or HIV infection; previous multiple gestations; previous preterm birth/low birth weight infants; in vitro fertilization procedures; placental, cervical/uterine abnormalities; history of infertility; history of drug abuse; and any medical conditions that required antibiotics prophylaxis. Patients’ anthropometric, demographic, and behavioral characteristics were collected. The periodontal clinical parameters were obtained from six sites per tooth: clinical attachment level, probing pocket depth, dental plaque index, and gingival bleeding index. Women were then allocated into two groups: mothers of preterm and/or low birth weight newborns (cases) and mothers of full-term and normal birth weight newborns (controls).Results
Periodontal clinical parameters were analyzed and reported separately for each group, and no significant differences were observed (p > 0.05). Logistic regression analysis revealed that periodontal clinical parameters were not associated with the adverse pregnancy outcomes.Conclusion(s)
After controlling for confounding factors, our results suggest that maternal periodontal disease is not a risk factor associated with preterm low birth weight infants.7.
Purpose
To study the effects of gestational transient thyrotoxicosis (GTT) on pregnancy outcomes.Methods
This case–control study retrospectively analyzed 7976 women with singleton pregnancies whose thyroid function was measured before 16 weeks of gestation and who delivered at ≥22 weeks of pregnancy. GTT was defined as hyperthyroidism (free thyroxine [FT4] level: ≥95th percentile) in the early pregnancy, which normalized in mid-pregnancy without thyroid-stimulating hormone receptor antibodies. Using data extracted from electronic records, we examined the association between GTT and the pregnancy outcomes (preterm delivery, gestational age at delivery, pregnancy induced hypertension (PIH), preeclampsia, placental abruption, caesarian section, birth weight, low birth weight, Apgar score, cord pH, stillbirth at gestational week ≥22, and neonatal death). We classified the cases into quartiles according to their FT4 values during the early pregnancy and investigated the association with the gestational age at delivery.Results
Two hundred and eight cases of GTT and 6317 cases with normal thyroid assessments were reviewed. GTT was associated with hyperemesis gravidarum, but not with stillbirth, preterm delivery, PIH, preeclampsia, placental abruption, or low birth weight. The gestation period was shorter in patients with GTT than in those with a normal thyroid function (38.69 ± 1.79 vs. 39.07 ± 1.64 weeks, p < 0.01). Higher FT4 levels during the early pregnancy were associated with earlier delivery (p = 0.02).Conclusions
GTT was associated with a lower gestational age at delivery but not with adverse pregnancy outcomes. There was a negative correlation between the FT4 values in the early pregnancy and the gestational period.8.

Background
The rate of preterm birth has been increasing worldwide, including in Brazil. This constitutes a significant public health challenge because of the higher levels of morbidity and mortality and long-term health effects associated with preterm birth. This study describes and quantifies factors affecting spontaneous and provider-initiated preterm birth in Brazil.Methods
Data are from the 2011–2012 “Birth in Brazil” study, which used a national population-based sample of 23,940 women. We analyzed the variables following a three-level hierarchical methodology. For each level, we performed non-conditional multiple logistic regression for both spontaneous and provider-initiated preterm birth.Results
The rate of preterm birth was 11.5 %?, (95 % confidence 10.3 % to 12.9 %) 60.7 % spontaneous - with spontaneous onset of labor or premature preterm rupture of membranes - and 39.3 % provider-initiated, with more than 90 % of the last group being pre-labor cesarean deliveries. Socio-demographic factors associated with spontaneous preterm birth were adolescent pregnancy, low total years of schooling, and inadequate prenatal care. Other risk factors were previous preterm birth (OR 3.74; 95 % CI 2.92–4.79), multiple pregnancy (OR 16.42; 95 % CI 10.56–25.53), abruptio placentae (OR 2.38; 95 % CI 1.27–4.47) and infections (OR 4.89; 95 % CI 1.72–13.88). In contrast, provider-initiated preterm birth was associated with private childbirth healthcare (OR 1.47; 95 % CI 1.09–1.97), advanced-age pregnancy (OR 1.27; 95 % CI 1.01–1.59), two or more prior cesarean deliveries (OR 1.64; 95 % CI 1.19–2.26), multiple pregnancy (OR 20.29; 95 % CI 12.58–32.72) and any maternal or fetal pathology (OR 6.84; 95 % CI 5.56–8.42).Conclusion
The high proportion of provider-initiated preterm birth and its association with prior cesarean deliveries and all of the studied maternal/fetal pathologies suggest that a reduction of this type of prematurity may be possible. The association of spontaneous preterm birth with socially-disadvantaged groups reaffirms that the reduction of social and health inequalities should continue to be a national priority.9.
Reducing stillbirths: prevention and management of medical disorders and infections during pregnancy
Esme V Menezes Mohammad Yawar Yakoob Tanya Soomro Rachel A Haws Gary L Darmstadt Zulfiqar A Bhutta 《BMC pregnancy and childbirth》2009,9(Z1):S4
Background
An estimated two-thirds of the world's 3.2 million stillbirths occur antenatally, prior to labour, and are often overlooked in policy and programs. Poorly recognised, untreated or inadequately treated maternal infections such as syphilis and malaria, and maternal conditions including hypertensive disorders, are known risk factors for stillbirth.Methods
We undertook a systematic review of the evidence for 16 antenatal interventions with the potential to prevent stillbirths. We searched a range of sources including PubMed and the Cochrane Library. For interventions with prior Cochrane reviews, we conducted additional meta-analyses including eligible newer randomised controlled trials following the Cochrane protocol. We focused on interventions deliverable at the community level in low-/middle-income countries, where the burden of stillbirths is greatest.Results
Few of the studies we included reported stillbirth as an outcome; most that did were underpowered to assess this outcome. While Cochrane reviews or meta-analyses were available for many interventions, few focused on stillbirth or perinatal mortality as outcomes, and evidence was frequently conflicting. Several interventions showed clear evidence of impact on stillbirths, including heparin therapy for certain maternal indications; syphilis screening and treatment; and insecticide-treated bed nets for prevention of malaria. Other interventions, such as management of obstetric intrahepatic cholestasis, maternal anti-helminthic treatment, and intermittent preventive treatment of malaria, showed promising impact on stillbirth rates but require confirmatory studies. Several interventions reduced known risk factors for stillbirth (e.g., anti-hypertensive drugs for chronic hypertension), yet failed to show statistically significant impact on stillbirth or perinatal mortality rates. Periodontal disease emerged as a clear risk factor for stillbirth but no interventions have reduced stillbirth rates.Conclusion
Evidence for some newly recognised risk factors for stillbirth, including periodontal disease, suggests the need for large, appropriately designed randomised trials to test whether intervention can minimise these risks and prevent stillbirths. Existing evidence strongly supports infection control measures, including syphilis screening and treatment and malaria prophylaxis in endemic areas, for preventing antepartum stillbirths. These interventions should be incorporated into antenatal care programs based on attributable risks and burden of disease.10.

Background
There is an overwhelming body of evidence strongly suggesting that periodontal infection may have a significant negative impact on pregnancy outcome in some women. The aim of this study was to determine the association between periodontal disease and preterm low birth weight of babies.Materials and Methods
A total of 300 pregnant women, between 20 and 24 weeks of gestation i.e., second trimester, were considered for the study. The periodontal status was recorded using the following parameters: probing pocket depth, clinical attachment level, oral hygiene index and plaque index. After initial examination in the second trimester, the pregnant women were followed till delivery of the baby. Postpartum data i.e., weight of baby, gestational age of pregnancy and type of delivery, were recorded.Results
Out of 300 pregnant women, 248 women had full-term delivery (12 low birth weight and 236 normal birth weight) while 52 had preterm delivery (6 normal birth weight and 46 low birth weight). There was significant association between body mass index and level of periodontal disease severity of pregnant women with birth weight of babies, gestational age of pregnant women and mode of delivery, respectively. As the level of periodontal disease severity increased, the proportion of delivering preterm and low birth weight babies also increased.Conclusion
The conclusions obtained revealed that Periodontal disease is a potential risk factor for preterm low birth weight babies of pregnant women.11.

Purpose
The purpose of the study is to calculate the cumulative pregnancy rate and cumulative live birth rate in women undergoing in vitro fertilization (IVF) at ages 44–45.Methods
The study calculated cumulative live pregnancy rate and cumulative live birth rate of 124 women aged 44 to 45 years old who commenced IVF treatment.Main outcome measures
The main outcome measures are cumulative live pregnancy rate and cumulative live birth rate.Results
Cumulative live pregnancy rates following 1, 2, 3, and 4 cycles were 5.6, 11, 17, and 20%, respectively, with no additional pregnancies in further cycles. Cumulative live birth rates following 1, 2, and 3 cycles were 1.6, 3, and 7%, respectively, with no additional live births in further cycles.Conclusions
The cumulative pregnancy rate rises during the first 4 cycles and cumulative live birth rate rises during the first 3 cycles, with no additional rise in pregnancies or deliveries thereafter, suggesting that it is futile to offer more than 3 cycles of treatment to 44–45-year-old women.12.
Background
Uterine-preserving prolapse surgery offers the chance to retain fertility; however, limited data is available for the safety of pregnancy following surgery and the effect of pregnancy on surgical outcome. Our operative technique involves mesh encircling the cervix and uterine arteries, which raises concerns that compromise of uterine blood flow during pregnancy may lead to foetal growth restriction. We also think this necessitates delivery by caesarean section. We report on six pregnancy outcomes following laparoscopic hysteropexy. Primary outcomes were live birth and birth weight. Secondary outcomes were integrity of mesh and immediate effect on prolapse.Results
All patients had successful pregnancy outcomes with birth weights on or above the 10th centile. There was no effect on mesh integrity seen in any of the cases. There was no deterioration in apical prolapse when assessed post delivery, but two patients had new onset anterior vaginal wall prolapse.Conclusions
We think our technique of hysteropexy is safe for those wishing to conceive. Larger numbers are needed to allow robust evidence-based guidance for patients and clinicians.13.
Background
Management of preterm labor by tocolysis remains an unmet medical need. Prostaglandins play a major role in regulation of uterine activity and in molecular mechanisms of human labor and parturition. There is some circumstantial evidence that prostaglandin F2α by action through the prostaglandin receptor subtype FP is effective in key events during labor uterine contraction, rupture of membranes and cervical dilation. This role of FP is briefly reviewed. In this study, we tested the hypothesis that an orally active and selective FP antagonist may arrest labor and delay parturition in animal models.Methods
We examined the effects of a small molecule selective antagonist of the FP receptor (AS604872) in inhibition of spontaneous uterine contraction in pregnant rat near term. We tested AS604872 for its ability to delay preterm birth in a mouse model in which the anti-progestin agent RU486 triggered parturition.Results
By oral or intravenous dosing AS604872 reduced markedly and dose-dependently the spontaneous uterine contractions in late-term pregnant rats at gestational days 19–21. In pregnant mice, AS604872 delayed the preterm birth caused by RU486 administration. The effect was dose-dependent with a significant increase in the mean delivery time of 16 and 33 hours at oral doses of 30 mg/kg and 100 mg/kg, respectively, in the case of labor triggered at gestational day 14. In both models AS604872 appeared more effective than the β-agonist ritodrine.Conclusion
The tocolytic activity displayed by a selective FP receptor antagonist supports a key role for the FP receptor in the pathophysiology of premature birth and demonstrates the therapeutic potential of an FP antagonist for the treatment of preterm labor cases in which uterine hyperactivity plays a dominant role.14.
Introduction
Preconception care recognizes that many adolescent girls and young women will be thrust into motherhood without the knowledge, skills or support they need. Sixty million adolescents give birth each year worldwide, even though pregnancy in adolescence has mortality rates at least twice as high as pregnancy in women aged 20-29 years. Reproductive planning and contraceptive use can prevent unintended pregnancies, unsafe abortions and sexually-transmitted infections in adolescent girls and women. Smaller families also mean better nutrition and development opportunities, yet 222 million couples continue to lack access to modern contraception.Method
A systematic review and meta-analysis of the evidence was conducted to ascertain the possible impact of preconception care for adolescents, women and couples of reproductive age on MNCH outcomes. A comprehensive strategy was used to search electronic reference libraries, and both observational and clinical controlled trials were included. Cross-referencing and a separate search strategy for each preconception risk and intervention ensured wider study capture.Results
Comprehensive interventions can prevent first pregnancy in adolescence by 15% and repeat adolescent pregnancy by 37%. Such interventions should address underlying social and community factors, include sexual and reproductive health services, contraceptive provision; personal development programs and emphasizes completion of education. Appropriate birth spacing (18-24 months from birth to next pregnancy compared to short intervals <6 months) can significantly lower maternal mortality, preterm births, stillbirths, low birth weight and early neonatal deaths.Conclusion
Improving adolescent health and preventing adolescent pregnancy; and promotion of birth spacing through increasing correct and consistent use of effective contraception are fundamental to preconception care. Promoting reproductive planning on a wider scale is closely interlinked with the reliable provision of effective contraception, however, innovative strategies will need to be devised, or existing strategies such as community-based health workers and peer educators may be expanded, to encourage girls and women to plan their families.15.

Objective
To study the incidence, maternal, and perinatal outcomes in intrahepatic cholestasis of pregnancy with active management.Materials and Methods
This observational study included 48 cases diagnosed as intrahepatic cholestasis of pregnancy. Medical treatment and active management (fetal surveillance and termination of pregnancy at 37–38 weeks) were offered to all. Maternal and perinatal outcomes are studied.Results
Incidence of ICP was 2.4 %. More than 86 % of patients presented with generalized pruritus mostly after 30 weeks. Incidences of Intrapartum abnormal cardiotocography (12.5 %) and thick meconium (8.33 %) were high. Cesarean section rate was high (41.66 %). Most common indications were CDMR, fetal distress, and non-progress of labor. Incidence of preterm labor, IUGR, Apgar score (<7), and neonatal admission rate were not high. There was one stillbirth at 36 weeks of gestation. Serum transaminase levels tended to be higher in patients with poor perinatal outcomes, such as stillbirth, fetal distress, and meconium-stained amniotic fluid.Conclusion
Serum transaminase levels tended to be higher in patients with poor perinatal outcome. Perinatal outcome is good with active management, at the cost of higher LSCS rate. Further randomized controlled trial of early versus spontaneous delivery may be justified.17.

Background
The course of pregnancy in a woman with portal hypertension is a difficult one as it is associated with complications like variceal bleeding, splenic artery rupture and coagulopathy. All these pose a threat to a woman’s life. Although this condition is rare, every obstetrician should have a high index of suspicion when an antenatal mother presents with splenomegaly, thrombocytopenia or hematemesis. Hence, we aimed to review maternal and fetal outcomes in pregnant women with portal hypertension.Methods
In a retrospective observational study, 41 women and 47 pregnancies were evaluated, from January 2000–December 2015 at Fernandez Hospital, a tertiary referral perinatal center. Maternal outcomes studied were variceal bleed during pregnancy, surgical procedures, morbidity and mortality. Neonatal variables were gestational age at delivery, birth weight and morbidities.Results
Mean maternal age was 26.4 years. Average gestational age at delivery was 36.5 weeks. Mean birth weight was 2507.5 g. There were three maternal deaths out of 47 deliveries, the cause of death was massive variceal bleed in one, the second one was due to cardiac arrest on MRI table, and the third death was due to splenic hilar vessel bleed. There was one stillbirth, and no neonatal deaths.Conclusion
A multidisciplinary approach is essential to improve perinatal outcomes in pregnancy complicated by portal hypertension. Surgical measures to reduce portal venous pressure done before pregnancy or beta blockers during pregnancy might help reduce sudden variceal bleeds.18.

Background
Screening and monitoring in pregnancy are strategies used by healthcare providers to identify high-risk pregnancies so that they can provide more targeted and appropriate treatment and follow-up care, and to monitor fetal well-being in both low- and high-risk pregnancies. The use of many of these techniques is controversial and their ability to detect fetal compromise often unknown. Theoretically, appropriate management of maternal and fetal risk factors and complications that are detected in pregnancy and labour could prevent a large proportion of the world's 3.2 million estimated annual stillbirths, as well as minimise maternal and neonatal morbidity and mortality.Methods
The fourth in a series of papers assessing the evidence base for prevention of stillbirths, this paper reviews available published evidence for the impact of 14 screening and monitoring interventions in pregnancy on stillbirth, including identification and management of high-risk pregnancies, advanced monitoring techniques, and monitoring of labour. Using broad and specific strategies to search PubMed and the Cochrane Library, we identified 221 relevant reviews and studies testing screening and monitoring interventions during the antenatal and intrapartum periods and reporting stillbirth or perinatal mortality as an outcome.Results
We found a dearth of rigorous evidence of direct impact of any of these screening procedures and interventions on stillbirth incidence. Observational studies testing some interventions, including fetal movement monitoring and Doppler monitoring, showed some evidence of impact on stillbirths in selected high-risk populations, but require larger rigourous trials to confirm impact. Other interventions, such as amniotic fluid assessment for oligohydramnios, appear predictive of stillbirth risk, but studies are lacking which assess the impact on perinatal mortality of subsequent intervention based on test findings. Few rigorous studies of cardiotocography have reported stillbirth outcomes, but steep declines in stillbirth rates have been observed in high-income settings such as the U.S., where cardiotocography is used in conjunction with Caesarean section for fetal distress.Conclusion
There are numerous research gaps and large, adequately controlled trials are still needed for most of the interventions we considered. The impact of monitoring interventions on stillbirth relies on use of effective and timely intervention should problems be detected. Numerous studies indicated that positive tests were associated with increased perinatal mortality, but while some tests had good sensitivity in detecting distress, false-positive rates were high for most tests, and questions remain about optimal timing, frequency, and implications of testing. Few studies included assessments of impact of subsequent intervention needed before recommending particular monitoring strategies as a means to decrease stillbirth incidence. In high-income countries such as the US, observational evidence suggests that widespread use of cardiotocography with Caesarean section for fetal distress has led to significant declines in stillbirth rates. Efforts to increase availability of Caesarean section in low-/middle-income countries should be coupled with intrapartum monitoring technologies where resources and provider skills permit.19.
Purpose
Vaginal colonization with Candida species (spp.) during pregnancy has been associated with impaired pregnancy outcomes. There is a reduction in spontaneous preterm birth among women with recurrent asymptomatic colonization of Candida who were treated with clotrimazole. This study aimed to evaluate the impact of the trimester of vulvovaginal colonization with Candida species.Methods
Data from all women, who were tested positive for the vaginal colonization with Candida spp. during the first or second trimester of pregnancy, and who registered for a planned birth at our tertiary referral center between 2005 and 2014 were retrospectively analyzed. Their preterm birth rate served as the primary outcome variable. Secondary outcome variables were neonatal birthweight and Apgar score.Results
Overall, 1066 women were eligible for the study. In 673 women (63%), who were diagnosed with Candida spp. during the first trimester of pregnancy, the rate of preterm birth was 10% (N?=?64). In 393 women (37%), who were diagnosed with candidosis during the second trimester, the preterm birth rate was 18% (N?=?71; p?=?0.0002). Neonates of women, who presented with vulvovaginal candidosis during the first trimester, had a mean birthweight of 3243 g, compared to 2989 g in the group with a second trimester colonization (p?<?0.0001).Conclusion
Women who are colonized with Candida spp. during the second trimester of pregnancy have higher rates of preterm birth and lower neonatal birthweight than those who are colonized during the first trimester of their pregnancy. Screening programs for asymptomatic Candida colonization should take this information into account.20.
