The dynamics of the female microbiome: unveiling abrupt changes of microbial domains across body sites from prepartum to postpartum phases. Microbiol Spectr 2024:e0014724. [PMID: 38917430 DOI: 10.1128/spectrum.00147-24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 05/17/2024] [Indexed: 06/27/2024] Open
Abstract
The microbial ecosystem of women undergoes enormous changes during pregnancy and the perinatal period. Little is known about the extent of changes in the maternal microbiome beyond the vaginal cavity and its recovery after birth. In this study, we followed pregnant women [maternal prepartum (mpre), n = 30] into the postpartum period [1 month postpartum, maternal postpartum (mpost), n = 30]. We profiled their oral, urinary, and vaginal microbiome; archaeome; mycobiome; and urinary metabolome and compared them with those of nonpregnant (np) women (n = 29). Overall, pregnancy status (np, mpre, and mpost) had a smaller effect on the microbiomes than body site, but massive transitions were observed for the oral and urogenital (vaginal and urinary) microbiomes. While the oral microbiome fluctuates during pregnancy but stabilizes rapidly within the first month postpartum, the urogenital microbiome is characterized by a major remodeling caused by a massive loss of Lactobacillus and thus a shift from Vaginal Community State Type (CST) I (40% of women) to CST IV (85% of women). The urinary metabolome rapidly reached an np-like composition after delivery, apart from lactose and oxaloacetic acid, which were elevated during active lactation. Fungal and archaeal profiles were indicative of pregnancy status. Methanobacterium signatures were found mainly in np women, and Methanobrevibacter showed an opposite behavior in the oral cavity (increased) and vagina (decreased) during pregnancy. Our findings suggest that the massive remodeling of the maternal microbiome and metabolome needs more attention and that potential interventions could be envisioned to optimize recovery and avoid long-term effects on maternal health and subsequent pregnancies. IMPORTANCE The perinatal microbiome is of specific interest for the health of the mother and infant. We therefore investigate the dynamics of the female microbiome from nonpregnant over prepartum to the postpartum period in urine and the oral and vaginal cavities. A specific focus of this study is put not only on the bacterial part of the microbiome but also on the underinvestigated contribution of fungi and archaea. To our knowledge, we present the first study highlighting those aspects. Our findings suggest that the massive remodeling of the maternal microbiome and metabolome needs more attention and that potential interventions could be envisioned to optimize recovery and avoid long-term effects on maternal health and subsequent pregnancies.

Abstract
Patient blood management is an evidence-based concept that seeks to minimize blood loss by maintaining adequate hemoglobin levels and optimizing hemostasis during surgery. Since the coronavirus disease 2019 pandemic, patient blood management has gained significance due to fewer blood donations and reduced amounts of blood stored for transfusion. Recently, the prevalence of postpartum hemorrhage (PPH), as well as the frequency of PPH-associated transfusions, has steadily increased. Therefore, proper blood transfusion is required to minimize PPH-associated complications while saving the patient's life. Several guidelines have attempted to apply this concept to minimize anemia during pregnancy and bleeding during delivery, prevent bleeding after delivery, and optimize recovery methods from anemia. This study systematically reviewed various guidelines to determine blood loss management in pregnant women.

Abstract
There have been widely documented beneficial role of vaginal Lactobacillus species as an important biomarker for vaginal health and healthy pregnancy progression. When translating this to clinical settings, pregnant women with low proportions of Lactobacillus and commensurately high proportion of rich and highly diverse abnormal microbiota are most likely to encounter negative pregnancy outcome such as preterm birth and postpartum complications. However, multiple literatures have also addressed this notion that the absence of a Lactobacillus-dominated microbiota does not appear to directly imply to a diseased condition and may not be a major determinant of negative obstetric outcome. Caesarian delivery is notably a risk factor for preterm birth and postpartum endometritis, yet recent data shows a trend in the overuse of CS across several populations. Growing evidence suggest the potential role of vaginal/uterine cleaning practice during CS procedures in influencing postpartum infections, however there is a controversy that this practice is associated with increased rates of postpartum endometritis. The preponderance of bacterial vaginosis associated bacteria vagitype at postpartum which persist for a long period of time even after lochia regression in some women may suggest why short interpregnancy interval may pose a potential risk for preterm birth, especially multigravidas. While specifically linking a community of microbes in the female reproductive tract or an exact causative infectious agent to preterm birth and postpartum pathologies remains elusive, clinical attention should also be drawn to the potential contribution of other factors such as short interpregnancy interval, birth mode, birth practices and the postpartum vaginal microbiome in preterm birth which is explicitly described in this narrative review.

Abstract
The normal physiologic changes of pregnancy complicate evaluation for sepsis and subsequent management. Previous sepsis studies have specifically excluded pregnant patients. This narrative review evaluates the presentation, scoring systems for risk stratification, diagnosis, and management of sepsis in pregnancy. Sepsis is potentially fatal, but literature for the evaluation and treatment of this condition in pregnancy is scarce. While the definition and considerations of sepsis have changed with large, randomized controlled trials, pregnancy has consistently been among the exclusion criteria. The two pregnancy-specific sepsis scoring systems, the modified obstetric early warning scoring system (MOEWS) and Sepsis in Obstetrics Score (SOS), present a number of limitations for application in the emergency department (ED) setting. Methods of generation and subsequently limited validation leave significant gaps in identification of septic pregnant patients. Management requires consideration of a variety of sources in the septic pregnant patient. The underlying physiologic nature of pregnancy also highlights the need to individualize resuscitation and critical care efforts in this unique patient population. Pregnant septic patients require specific considerations and treatment goals to provide optimal care for this particular population. Guidelines and scoring systems currently exist, but further studies are required.

Abstract
PURPOSE To evaluate the efficacy of preoperative vaginal cleansing using povidone-iodine solution 10% on rates of post cesarean section (CS) infectious morbidities (endometritis, febrile morbidity and wound infection). METHODS This prospective randomized trial was conducted among 226 pregnant women scheduled for term elective CS. Patients were equally divided into two groups by simple randomization method. The study group had preoperative vaginal cleansing using povidone-iodine solution 10% for about 1 min, while the control group did not. All cases received the prophylactic antibiotics and the usual abdominal scrub. Adverse post CS infectious morbidities such as endometritis, febrile morbidity and wound infection were observed at the time of hospital discharge and weekly for 6 weeks postpartum. RESULTS Both groups were matched regarding the baseline patients' characteristics. Overall, post-CS infectious morbidity was significantly reduced from 20.7% in the control group to 7.5% in the intervention group. Marked significant reduction was seen in the incidence of endometritis (11.8% in the control group versus 2.8% in the intervention group). However, maternal fever and wound infection showed no significant difference between both groups. CONCLUSION Vaginal cleansing with povidone-iodine solution 10% prior to elective CS appears to be effective in reducing rates of post-CS infectious morbidity mainly endometritis.

Abstract
BACKGROUND Post-caesarean section infection is a cause of maternal morbidity and mortality. Administration of antibiotic prophylaxis is recommended for preventing infection after caesarean delivery. The route of administration of antibiotic prophylaxis should be effective, safe and convenient. Currently, there is a lack of synthesised evidence regarding the benefits and harms of different routes of antibiotic prophylaxis for preventing infection after caesarean section. OBJECTIVES The aim of this review was to assess the benefits and harms of different routes of prophylactic antibiotics given for preventing infectious morbidity in women undergoing caesarean section. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 January 2016), ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (6 January 2016) and reference lists of retrieved studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing at least two alternative routes of antibiotic prophylaxis for caesarean section (both elective and emergency). Cross-over trials and quasi-RCTs were not eligible for inclusion. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion, assessed the risk of bias and extracted data from the included studies. These steps were checked by a third review author. MAIN RESULTS We included 10 studies (1354 women). The risk of bias was unclear or high in most of the included studies.All of the included trials involved women undergoing caesarean section whether elective or non-elective. Intravenous antibiotics versus antibiotic irrigation (nine studies, 1274 women) Nine studies (1274 women) compared the administration of intravenous antibiotics with antibiotic irrigation. There were no clear differences between groups in terms of this review's maternal primary outcomes: endometritis (risk ratio (RR) 0.95, 95% confidence interval (CI) 0.70 to 1.29; eight studies (966 women) (low-quality evidence)); wound infection (RR 0.49, 95% CI 0.17 to 1.43; seven studies (859 women) (very low-quality evidence)). The outcome of infant sepsis was not reported in the included studies.In terms of this review's maternal secondary outcomes, there were no clear differences between intravenous antibiotic or irrigation antibiotic groups in terms of postpartum febrile morbidity (RR 0.87, 95% CI 0.48 to 1.60; three studies (264 women) (very low-quality evidence)); or urinary tract infection (RR 0.74, 95% CI 0.25 to 2.15; five studies (660 women) (very low-quality evidence)). In terms of adverse effects of the treatment on the women, no drug allergic reactions were reported in three studies (284 women) (very low-quality evidence), and there were no cases of serious infectious complications reported (very low-quality evidence). There was no clear difference between groups in terms of maternal length of hospital stay (mean difference (MD) 0.28 days, 95% CI -0.22 to 0.79 days, (random-effects analysis), four studies (512 women). No data were reported for the number of women readmitted to hospital. For the baby, there were no data reported in relation to oral thrush, infant length of hospital stay or immediate adverse effects of the antibiotics on the infant. Intravenous antibiotic prophylaxis versus oral antibiotic prophylaxis (one study, 80 women) One study (80 women) compared an intravenous versus an oral route of administration of prophylactic antibiotics, but did not report any of this review's primary or secondary outcomes. AUTHORS' CONCLUSIONS There was no clear difference between irrigation and intravenous antibiotic prophylaxis in reducing the risk of post-caesarean endometritis. For other outcomes, there is insufficient evidence regarding which route of administration of prophylactic antibiotics is most effective at preventing post-caesarean infections. The quality of evidence was very low to low, mainly due to limitations in study design and imprecision. Furthermore, most of the included studies were underpowered (small sample sizes with few events). Therefore, we advise caution in the interpretation and generalisability of the results.For future research, there is a need for well-designed, properly-conducted, and clearly-reported RCTs. Such studies should evaluate the more recently available antibiotics, elaborating on the various available routes of administration, and exploring potential neonatal side effects of such interventions.

Abstract
BACKGROUND Postpartum sepsis accounts for most maternal deaths between three and seven days postpartum, when most mothers, even those who deliver in facilities, are at home. Case fatality rates for untreated women are very high. Newborns of ill women have substantially higher infection risk. METHODS/DESIGN The objectives of this study are to: (1) create, field-test and validate a tool for community health workers to improve diagnostic accuracy of suspected puerperal sepsis; (2) measure incidence and identify associated risk factors and; (3) describe etiologic agents responsible and antibacterial susceptibility patterns. This prospective cohort study builds on the Aetiology of Neonatal Infection in South Asia study in three sites: Sylhet, Bangladesh and Karachi and Matiari, Pakistan. Formative research determined local knowledge of symptoms and signs of postpartum sepsis, and a systematic literature review was conducted to design a diagnostic tool for community health workers to use during ten postpartum home visits. Suspected postpartum sepsis cases were referred to study physicians for independent assessment, which permitted validation of the tool. Clinical specimens, including urine, blood, and endometrial material, were collected for etiologic assessment and antibiotic sensitivity. All women with puerperal sepsis were given appropriate antibiotics. DISCUSSION This is the first large population-based study to expand community-based surveillance for diagnoses, referral and treatment of newborn sepsis to include maternal postpartum sepsis. Study activities will lead to development and validation of a diagnostic tool for use by community health workers in resource-poor countries. Understanding the epidemiology and microbiology of postpartum sepsis will inform prevention and treatment strategies and improve understanding of linkages between maternal and neonatal infections.

Abstract
The year 2015 marked the 200th anniversary of the birth of Ignaz Semmelweis, the Hungarian physician who identified unhygienic practices of physicians as a major cause of childbed fever or puerperal sepsis. Although such practices have largely disappeared as a factor in the development of chorioamnionitis and postpartum or puerperal endometritis, it is appropriate that this article on sepsis in pregnancy acknowledges his contributions to maternal health. This review describes the incidence and mortality of sepsis in pregnancy, methods to identify and define sepsis in this population, including scoring systems, causes, and sites of infection during pregnancy and parturition and management guidelines.

Abstract
OBJECTIVE Antibiotic administration is a standard practice in preterm premature rupture of membranes (PROM). Specific anti-microbial agents often include ampicillin and/or erythromycin. Anaerobes and genital mycoplasmas are frequently involved in preterm PROM, but are not adequately covered by antibiotics routinely used in clinical practice. Our objective was to compare outcomes of PROM treated with standard antibiotic administration versus a new combination more effective against these bacteria. STUDY DESIGN A retrospective study compared perinatal outcomes in 314 patients with PROM <34 weeks receiving anti-microbial regimen 1 (ampicillin and/or cephalosporins; n = 195, 1993-2003) versus regimen 2 (ceftriaxone, clarithromycin and metronidazole; n = 119, 2003-2012). Intra-amniotic infection/inflammation was assessed by positive amniotic fluid culture and/or an elevated amniotic fluid MMP-8 concentration (>23 ng/mL). RESULTS (1) Patients treated with regimen 2 had a longer median antibiotic-to-delivery interval than those with regimen 1 [median (interquartile range) 23 d (10-51 d) versus 12 d (5-52 d), p < 0.01]; (2) patients who received regimen 2 had lower rates of acute histologic chorioamnionitis (50.5% versus 66.7%, p < 0.05) and funisitis (13.9% versus 42.9%, p < 0.001) than those who had received regimen 1; (3) the rates of intra-ventricular hemorrhage (IVH) and cerebral palsy (CP) were significantly lower in patients allocated to regimen 2 than regimen 1 (IVH: 2.1% versus 19.0%, p < 0.001 and CP: 0% versus 5.7%, p < 0.05); and (4) subgroup analysis showed that regimen 2 improved perinatal outcomes in pregnancies with intra-amniotic infection/inflammation, but not in those without intra-amniotic infection/inflammation (after adjusting for gestational age and antenatal corticosteroid administration). CONCLUSION A new antibiotic combination consisting of ceftriaxone, clarithromycin, and metronidazole prolonged the latency period, reduced acute histologic chorioamnionitis/funisitis, and improved neonatal outcomes in patients with preterm PROM. These findings suggest that the combination of anti-microbial agents (ceftriaxone, clarithromycin, and metronidazole) may improve perinatal outcome in preterm PROM.

Abstract

Puerperal genital tract infections include endometritis as well as abdominal and perineal wound infections. These infections interrupt postpartum restoration, increase the potential for readmission to a health care facility, and can interfere with maternal-infant bonding. In addition, unrecognized or improperly treated genital tract infection could extend to other sites via venous circulation or the lymphatic system and increase the risk of severe complications or sepsis. Midwives are leaders in education, low rates of intervention, and prompt recognition of deviation from normal. Because puerperal genital tract infection usually begins after discharge, detailed education for women will encourage preventative health care, prompt recognition, and treatment.

The vaginal microbiome during pregnancy and the postpartum period in a European population. Sci Rep 2015; 5:8988. [PMID: 25758319 PMCID: PMC4355684 DOI: 10.1038/srep08988] [Citation(s) in RCA: 346] [Impact Index Per Article: 38.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2014] [Accepted: 02/11/2015] [Indexed: 12/29/2022] Open
Abstract
The composition and structure of the pregnancy vaginal microbiome may influence susceptibility to adverse pregnancy outcomes. Studies on the pregnant vaginal microbiome have largely been limited to Northern American populations. Using MiSeq sequencing of 16S rRNA gene amplicons, we characterised the vaginal microbiota of a mixed British cohort of women (n = 42) who experienced uncomplicated term delivery and who were sampled longitudinally throughout pregnancy (8–12, 20–22, 28–30 and 34–36 weeks gestation) and 6 weeks postpartum. We show that vaginal microbiome composition dramatically changes postpartum to become less Lactobacillus spp. dominant with increased alpha-diversity irrespective of the community structure during pregnancy and independent of ethnicity. While the pregnancy vaginal microbiome was characteristically dominated by Lactobacillus spp. and low alpha-diversity, unlike Northern American populations, a significant number of pregnant women this British population had a L. jensenii-dominated microbiome characterised by low alpha-diversity. L. jensenii was predominantly observed in women of Asian and Caucasian ethnicity whereas L. gasseri was absent in samples from Black women. This study reveals new insights into biogeographical and ethnic effects upon the pregnancy and postpartum vaginal microbiome and has important implications for future studies exploring relationships between the vaginal microbiome, host health and pregnancy outcomes.

Abstract
BACKGROUND Postpartum endometritis occurs when vaginal organisms invade the endometrial cavity during the labor process and cause infection. This is more common following cesarean birth. The condition warrants antibiotic treatment. OBJECTIVES Systematically, to review treatment failure and other complications of different antibiotic regimens for postpartum endometritis. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 November 2014) and reference lists of retrieved studies. SELECTION CRITERIA We included randomized trials of different antibiotic regimens after cesarean birth or vaginal birth; no quasi-randomized trials were included. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. MAIN RESULTS The review includes a total of 42 trials, and 40 of these trials contributed data on 4240 participants.Regarding the primary outcomes, seven studies compared clindamycin plus an aminoglycoside versus penicillins and showed fewer treatment failures (risk ratio (RR) 0.65, 95% confidence interval (CI) 0.46 to 0.90). There were more treatment failures in those treated with an aminoglycoside plus penicillin when compared to those treated with gentamycin/clindamycin (RR 2.57, 95% CI 1.48 to 4.46). There were more treatment failures (RR 1.66, 95% CI 1.01 to 2.74) and wound infections (RR 1.88, 95% CI 1.08 to 3.28) in those treated with second or third generation cephalosporins (excluding cephamycins) versus those treated with clindamycin plus gentamycin. In four studies comparing once-daily with thrice-daily dosing of gentamicin, there were fewer failures with once-daily dosing. There were more treatment failures (RR 1.94, 95% CI 1.38 to 2.72) and wound infections (RR 1.88, 95% CI 1.17 to 3.02) in those treated with a regimen with poor activity against penicillin-resistant anaerobic bacteria as compared to those treated with a regimen with good activity against penicillin-resistant anaerobic bacteria. There were no differences between groups with respect to severe complications and no trials reported any maternal deaths.Regarding the secondary outcomes, three studies that compared continued oral antibiotic therapy after intravenous therapy with no oral therapy, found no differences in recurrent endometritis or other outcomes. Four trials that compared clindamycin plus aminoglycoside versus cephalosporins identified fewer wound infections in those treated with clindamycin plus an aminoglycoside (RR 0.53, 95% CI 0.30 to 0.93). There were no differences between groups for the outcomes of allergic reactions. The overall risk of bias was unclear in the most of the studies. The quality of the evidence using GRADE comparing clindamycin and an aminoglycoside with another regimen (compared with cephalosporins or penicillins) was low to very low for therapeutic failure, severe complications, wound infection and allergic reaction. AUTHORS' CONCLUSIONS The combination of clindamycin and gentamicin is appropriate for the treatment of endometritis. Regimens with good activity against penicillin-resistant anaerobic bacteria are better than those with poor activity against penicillin-resistant anaerobic bacteria. There is no evidence that any one regimen is associated with fewer side-effects. Following clinical improvement of uncomplicated endometritis which has been treated with intravenous therapy, the use of additional oral therapy has not been proven to be beneficial.

Abstract
BACKGROUND Cesarean delivery is one of the most common surgical procedures performed by obstetricians. Infectious morbidity after cesarean delivery can have a tremendous impact on the postpartum woman's return to normal function and her ability to care for her baby. Despite the widespread use of prophylactic antibiotics, postoperative infectious morbidity still complicates cesarean deliveries. OBJECTIVES To determine if cleansing the vagina with an antiseptic solution before a cesarean delivery decreases the risk of maternal infectious morbidities, including endometritis and wound complications. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (10 December 2014). SELECTION CRITERIA We included randomized and quasi-randomized trials assessing the impact of vaginal cleansing immediately before cesarean delivery with any type of antiseptic solution versus a placebo solution/standard of care on post-cesarean infectious morbidity. DATA COLLECTION AND ANALYSIS We independently assessed eligibility and quality of the studies. MAIN RESULTS Seven trials randomizing 2816 women (2635 analyzed) evaluated the effects of vaginal cleansing (all with povidone-iodine) on post-cesarean infectious morbidity. The risk of bias was generally low, with the quality of most of the studies being high. Vaginal preparation immediately before cesarean delivery significantly reduced the incidence of post-cesarean endometritis from 8.3% in control groups to 4.3% in vaginal cleansing groups (average risk ratio (RR) 0.45, 95% confidence interval (CI) 0.25 to 0.81, seven trials, 2635 women). The risk reduction was particularly strong for women who were already in labor at the time of the cesarean delivery (7.4% in the vaginal cleansing group versus 13.0% in the control group; RR 0.56, 95% CI 0.34 to 0.95, three trials, 523 women) and for women with ruptured membranes (4.3% in the vaginal cleansing group versus 17.9% in the control group; RR 0.24, 95% CI 0.10 to 0.55, three trials, 272 women). No other outcomes realized statistically significant differences between the vaginal cleansing and control groups. No adverse effects were reported with the povidone-iodine vaginal cleansing.The quality of the evidence using GRADE was low for post-cesarean endometritis, moderate for postoperative fever, and low for wound infection. AUTHORS' CONCLUSIONS Vaginal preparation with povidone-iodine solution immediately before cesarean delivery reduces the risk of postoperative endometritis. This benefit is particularly realized for women undergoing cesarean delivery, who are already in labor or who have ruptured membranes. As a simple, generally inexpensive intervention, providers should consider implementing preoperative vaginal cleansing with povidone-iodine before performing cesarean deliveries.

Abstract
In this first paper in a series of four papers on midwifery, we aimed to examine, comprehensively and systematically, the contribution midwifery can make to the quality of care of women and infants globally, and the role of midwives and others in providing midwifery care. Drawing on international definitions and current practice, we mapped the scope of midwifery. We then developed a framework for quality maternal and newborn care using a mixed-methods approach including synthesis of findings from systematic reviews of women's views and experiences, effective practices, and maternal and newborn care providers. The framework differentiates between what care is provided and how and by whom it is provided, and describes the care and services that childbearing women and newborn infants need in all settings. We identified more than 50 short-term, medium-term, and long-term outcomes that could be improved by care within the scope of midwifery; reduced maternal and neonatal mortality and morbidity, reduced stillbirth and preterm birth, decreased number of unnecessary interventions, and improved psychosocial and public health outcomes. Midwifery was associated with more efficient use of resources and improved outcomes when provided by midwives who were educated, trained, licensed, and regulated. Our findings support a system-level shift from maternal and newborn care focused on identification and treatment of pathology for the minority to skilled care for all. This change includes preventive and supportive care that works to strengthen women's capabilities in the context of respectful relationships, is tailored to their needs, focuses on promotion of normal reproductive processes, and in which first-line management of complications and accessible emergency treatment are provided when needed. Midwifery is pivotal to this approach, which requires effective interdisciplinary teamwork and integration across facility and community settings. Future planning for maternal and newborn care systems can benefit from using the quality framework in planning workforce development and resource allocation.

Abstract
The epidemiology of infections in the puerperium (post partum period) is not well understood and remains underestimated because surveillance systems are often limited to the acute care setting. The most common source of persistent fever after delivery is genital tract infection for which diagnosis remains mostly clinical and antibiotic treatment empiric. This review will emphasize surgical site infections (SSIs) and endometritis. Septic thrombo-phlebitis, mastitis, urinary tract infections and rare infections will be covered in less detail. Puerperal sepsis will not be reviewed.

Abstract
Childbirth and the postnatal period, spanning from right after birth to the following several weeks, presents a time in which the number of deaths reported still remain alarmingly high. Worldwide, about 800 women die from pregnancy- or childbirth-related complications daily while almost 75% of neonatal deaths occur within the first seven days of delivery and a vast majority of these occur in the first 24 hours. Unfortunately, this alarming trend of mortality persists, as 287,000 women lost their lives to pregnancy and childbirth related causes in 2010. Almost all of these deaths were preventable and occurred in low-resource settings, pointing towards dearth of adequate facilities in these parts of the world. The main objective of this paper is to review the evidence based childbirth and post natal interventions which have a beneficial impact on maternal and newborn outcomes. It is a compilation of existing, new and updated interventions designed to help physicians and policy makers and enable them to reduce the burden of maternal and neonatal morbidities and mortalities. Interventions during the post natal period that were found to be associated with a decrease in maternal and neonatal morbidity and mortality included: advice and support of family planning, support and promotion of early initiation and continued breastfeeding; thermal care or kangaroo mother care for preterm and/or low birth weight babies; hygienic care of umbilical cord and skin following delivery, training health personnel in basic neonatal resuscitation; and postnatal visits. Adequate delivery of these interventions is likely to bring an unprecedented decrease in the number of deaths reported during childbirth.

Abstract
In an effort to accelerate progress towards achieving Millennium Development Goal (MDG) 4 and 5, provision of essential reproductive, maternal, newborn and child health (RMNCH) interventions is being considered. Not only should a state-of-the-art approach be taken for services delivered to the mother, neonate and to the child, but services must also be deployed across the household to hospital continuum of care approach and in the form of packages. The paper proposed several packages for improved maternal, newborn and child health that can be delivered across RMNCH continuum of care. These packages include: supportive care package for women to promote awareness related to healthy pre-pregnancy and pregnancy interventions; nutritional support package for mother to improve supplementation of essential nutrients and micronutrients; antenatal care package to detect, treat and manage infectious and noninfectious diseases and promote immunization; high risk care package to manage preeclampsia and eclampsia in pregnancy; childbirth package to promote support during labor and importance of skilled birth attendance during labor; essential newborn care package to support healthy newborn care practices; and child health care package to prevent and manage infections. This paper further discussed the implementation strategies for employing these interventions at scale.

The emergence of Clostridium difficile infection among peripartum women: a case-control study of a C. difficile outbreak on an obstetrical service. Infect Dis Obstet Gynecol 2011; 2011:267249.

Abstract
OBJECTIVE An outbreak of 20 peripartum Clostridium difficile infections (CDI) occurred on the obstetrical service at the University of Washington Medical Center (UWMC) between April 2006 and June 2007. In this report, we characterize the clinical manifestations, describe interventions that appeared to reduce CDI, and determine potential risk factors for peripartum CDI. METHODS An investigation was initiated after the first three peripartum CDI cases. Based on the findings, enhanced infection control measures and a modified antibiotic regimen were implemented. We conducted a case-control study of peripartum cases and unmatched controls. RESULTS During the outbreak, there was an overall incidence of 7.5 CDI cases per 1000 deliveries. Peripartum CDI infection compared to controls was significantly associated with cesarean delivery (70% versus 34%; P=0.03), antibiotic use (95% versus 56%; P=0.001), chorioamnionitis (35% versus 5%; P=0.001), and the use of the combination of ampicillin, gentamicin, and clindamycin (50% versus 3%; P<0.001). Use of combination antibiotics remained a significant independent risk factor for CDI in the multivariate analysis. CONCLUSIONS The outbreak was reduced after the implementation of multiple infection control measures and modification of antibiotic use. However, sporadic CDI continued for 8 months after these measures slowed the outbreak. Peripartum women appear to be another population susceptible to CDI.

Abstract
OBJECTIVE We sought to investigate whether oral antibiotics are necessary, after 48 hours of clinical improvement, in uncomplicated septic abortion. STUDY DESIGN In a randomized double-blind clinical trial, 56 women with uncomplicated septic abortion were treated with intravenous antibiotics, followed by uterine evacuation. On hospital discharge (day 1), patients were randomized to receive either oral doxycycline plus metronidazole or placebo, until completing 10 days of treatment. Clinical cure was defined by the absence of fever (<37.7°C), reduced vaginal bleeding, and minimal or no pelvic pain. RESULTS Cure was observed in all 56 patients. The institutional review board stopped the treatment arm as it was adding risk with no further benefit to the patients. An observational cohort with additional 75 cases was followed up in the no treatment arm and no failure was identified (probability of an adverse event, 0%; 95% confidence interval, 0-0.03). CONCLUSION After 48 hours of clinical improvement, antibiotics may not be necessary.

Abstract
BACKGROUND Approximately one-quarter of all pregnancy- and delivery-related maternal deaths worldwide occur in India. Taking into account the costs, feasibility, and operational complexity of alternative interventions, we estimate the clinical and population-level benefits associated with strategies to improve the safety of pregnancy and childbirth in India. METHODS AND FINDINGS Country- and region-specific data were synthesized using a computer-based model that simulates the natural history of pregnancy (both planned and unintended) and pregnancy- and childbirth-associated complications in individual women; and considers delivery location, attendant, and facility level. Model outcomes included clinical events, population measures, costs, and cost-effectiveness ratios. Separate models were adapted to urban and rural India using survey-based data (e.g., unmet need for birth spacing/limiting, facility births, skilled birth attendants). Model validation compared projected maternal indicators with empiric data. Strategies consisted of improving coverage of effective interventions that could be provided individually or packaged as integrated services, could reduce the incidence of a complication or its case fatality rate, and could include improved logistics such as reliable transport to an appropriate referral facility as well as recognition of referral need and quality of care. Increasing family planning was the most effective individual intervention to reduce pregnancy-related mortality. If over the next 5 y the unmet need for spacing and limiting births was met, more than 150,000 maternal deaths would be prevented; more than US$1 billion saved; and at least one of every two abortion-related deaths averted. Still, reductions in maternal mortality reached a threshold ( approximately 23%-35%) without including strategies that ensured reliable access to intrapartum and emergency obstetrical care (EmOC). An integrated and stepwise approach was identified that would ultimately prevent four of five maternal deaths; this approach coupled stepwise improvements in family planning and safe abortion with consecutively implemented strategies that incrementally increased skilled attendants, improved antenatal/postpartum care, shifted births away from home, and improved recognition of referral need, transport, and availability/quality of EmOC. The strategies in this approach ranged from being cost-saving to having incremental cost-effectiveness ratios less than US$500 per year of life saved (YLS), well below India's per capita gross domestic product (GDP), a common benchmark for cost-effectiveness. CONCLUSIONS Early intensive efforts to improve family planning and control of fertility choices and to provide safe abortion, accompanied by a paced systematic and stepwise effort to scale up capacity for integrated maternal health services over several years, is as cost-effective as childhood immunization or treatment of malaria, tuberculosis, or HIV. In just 5 y, more than 150,000 maternal deaths would be averted through increasing contraception rates to meet women's needs for spacing and limiting births; nearly US$1.5 billion would be saved by coupling safe abortion to aggressive family planning efforts; and with stepwise investments to improve access to pregnancy-related health services and to high-quality facility-based intrapartum care, more than 75% of maternal deaths could be prevented. If accomplished over the next decade, the lives of more than one million women would be saved.

Abstract
BACKGROUND It is important that healthcare provided in crisis settings is based on the best available research evidence. We reviewed guidelines for child and perinatal health care in crisis situations to determine whether they were based on research evidence, whether Cochrane systematic reviews were available in the clinical areas addressed by these guidelines and whether summaries of these reviews were provided in Evidence Aid. METHODS Broad internet searches were undertaken to identify relevant guidelines. Guidelines were appraised using AGREE and the clinical areas that were relevant to perinatal or child health were extracted. We searched The Cochrane Database of Systematic Reviews to identify potentially relevant reviews. For each review we determined how many trials were included, and how many were conducted in resource-limited settings. RESULTS Six guidelines met selection criteria. None of the included guidelines were clearly based on research evidence. 198 Cochrane reviews were potentially relevant to the guidelines. These reviews predominantly addressed nutrient supplementation, breastfeeding, malaria, maternal hypertension, premature labour and prevention of HIV transmission. Most reviews included studies from developing settings. However for large portions of the guidelines, particularly health services delivery, there were no relevant reviews. Only 18 (9.1%) reviews have summaries in Evidence Aid. CONCLUSIONS We did not identify any evidence-based guidelines for perinatal and child health care in disaster settings. We found many Cochrane reviews that could contribute to the evidence-base supporting future guidelines. However there are important issues to be addressed in terms of the relevance of the available reviews and increasing the number of reviews addressing health care delivery.

Abstract
BACKGROUND Cesarean delivery is one of the most common surgical procedures performed by obstetricians. Infectious morbidity after cesarean delivery can have a tremendous impact on the postpartum woman's return to normal function and her ability to care for her baby. Despite the widespread use of prophylactic antibiotics, postoperative infectious morbidity still complicates cesarean deliveries. OBJECTIVES To determine if cleansing the vagina with an antiseptic solution before a cesarean delivery decreases the risk of maternal infectious morbidities, including endometritis and wound complications. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (December 2009). SELECTION CRITERIA We included randomized trials assessing the impact of vaginal cleansing immediately before cesarean delivery with any type of antiseptic solution versus a placebo solution/standard of care on post-cesarean infectious morbidity. DATA COLLECTION AND ANALYSIS We independently assessed eligibility and quality of the studies. MAIN RESULTS Four trials (involving 1361 randomized and 1198 analyzed women) evaluated the effects of vaginal cleansing (all with povidone-iodine) on post-cesarean infectious morbidity. The risk of bias was generally low, with the quality of most of the studies being high. Vaginal preparation immediately before cesarean delivery significantly reduced the incidence of post-cesarean endometritis from 9.4% in control groups to 5.2% in vaginal cleansing groups (risk ratio (RR) 0.57, 95% confidence interval (CI) 0.38 to 0.87, four trials, 1198 women). The risk reduction was particularly strong for women with ruptured membranes (1.4% in the vaginal cleansing group versus 15.4% in the control group; RR 0.13, 95% CI 0.02 to 0.66, two trials, 148 women). No other outcomes realized statistically significant differences between the vaginal cleansing and control groups. No adverse effects were reported with the povidone-iodine vaginal cleansing. AUTHORS' CONCLUSIONS Vaginal preparation with povidone-iodine solution immediately before cesarean delivery reduces the risk of postoperative endometritis. This benefit is particularly realized for women undergoing cesarean delivery with ruptured membranes. As a simple, generally inexpensive intervention, providers should consider implementing preoperative vaginal cleansing with povidone-iodine before performing cesarean deliveries.

Abstract
OBJECTIVE The objective of the study was to determine whether vaginal preparation with povidone iodine before cesarean delivery decreased the risk of postoperative maternal morbidities. STUDY DESIGN The design of the study was a randomized, controlled trial in women undergoing cesarean delivery with subjects assigned to have a preoperative vaginal cleansing with povidone iodine or to a standard care group (no vaginal wash). The primary outcome was a composite of postoperative fever, endometritis, sepsis, readmission, wound infection, or complication. RESULTS There were 155 vaginal cleansing subjects and 145 control subjects. Overall, 9.0% developed the composite outcome, with fewer women in the cleansing group (6.5%) compared with the control group (11.7%), although the difference was not statistically significant (relative risk, 0.55; 95% confidence interval, 0.26-1.11; P = .11). Length of surgery, being in labor, and having a dilated cervix were all associated with the composite morbidity outcome. CONCLUSION Vaginal cleansing with povidone iodine before cesarean delivery may decrease postoperative morbidities, although the reduction is not statistically significant.

Abstract
Despite advances in peripartum care, maternal morbidity and mortality associated with infections in pregnancy are increasing even in developed countries. Recently published data from the Center for Disease Control's Pregnancy Mortality Surveillance System indicates that although maternal mortality from hemorrhage, embolism, and anesthesia has declined in the United States, the proportion of maternal deaths due to infections has increased. During 1991–7 infection accounted for 13.2% of pregnancy-related deaths overall and 36.3% of abortion-related deaths. The greatest infection risk is found in blacks, older women, women without prenatal care, and women with multiple pregnancy. In the United States pregnancy rates are stable or increasing in these groups. Infection is also a major cause of morbidity and mortality for the fetus and newborn. Many perinatal infections are associated with intra-uterine growth retardation and low birthweight, or cause fetal and neonatal brain injury. Infections, particularly bacterial vaginosis and chorioamnionitis, can result in preterm delivery of live-born infants (delivery before 37 weeks gestation), or stillbirth. A multitude of immunologic, endocrinologic, metabolic, physiologic, and anatomic changes influence the likelihood and course of many infections during pregnancy. Some of these changes are intrinsic, and occur in all normal pregnancies, while others occur to varying degrees in normal and abnormal pregnancies.

Abstract
BACKGROUND In Mexico, the lifetime risk of dying from maternal causes is 1 in 370 compared to 1 in 2,500 in the U.S. Although national efforts have been made to improve maternal services in the last decade, it is unclear if Millennium Development Goal 5--to reduce maternal mortality by three-quarters by 2015--will be met. METHODOLOGY/PRINCIPAL FINDINGS We developed an empirically calibrated model that simulates the natural history of pregnancy and pregnancy-related complications in a cohort of 15-year-old women followed over their lifetime. After synthesizing national and sub-national trends in maternal mortality, the model was calibrated to current intervention-specific coverage levels and validated by comparing model-projected life expectancy, total fertility rate, crude birth rate and maternal mortality ratio with Mexico-specific data. Using both published and primary data, we assessed the comparative health and economic outcomes of alternative strategies to reduce maternal morbidity and mortality. A dual approach that increased coverage of family planning by 15%, and assured access to safe abortion for all women desiring elective termination of pregnancy, reduced mortality by 43% and was cost saving compared to current practice. The most effective strategy added a third component, enhanced access to comprehensive emergency obstetric care for at least 90% of women requiring referral. At a national level, this strategy reduced mortality by 75%, cost less than current practice, and had an incremental cost-effectiveness ratio of $300 per DALY relative to the next best strategy. Analyses conducted at the state level yielded similar results. CONCLUSIONS/SIGNIFICANCE Increasing the provision of family planning and assuring access to safe abortion are feasible, complementary and cost-effective strategies that would provide the greatest benefit within a short-time frame. Incremental improvements in access to high-quality intrapartum and emergency obstetric care will further reduce maternal deaths and disability.

Abstract
BACKGROUND In maternal medicine, research evidence is scattered making it difficult to access information for clinical decision making. Systematic reviews of good methodological quality are essential to provide valid inferences and to produce usable evidence summaries to guide management. This review assesses the methodological features of existing systematic reviews in maternal medicine, comparing Cochrane and non-Cochrane reviews in maternal medicine. METHODS Medline, Embase, Database of Reviews of Effectiveness (DARE) and Cochrane Database of Systematic Reviews (CDSR) were searched for relevant reviews published between 2001 and 2006. We selected those reviews in which a minimum of two databases were searched and the primary outcome was related to the maternal condition. The selected reviews were assessed for information on framing of question, literature search and methods of review. RESULTS Out of 2846 citations, 68 reviews were selected. Among these, 39 (57%) were Cochrane reviews. Most of the reviews (50/68, 74%) evaluated therapeutic interventions. Overall, 54/68 (79%) addressed a focussed question. Although 64/68 (94%) reviews had a detailed search description, only 17/68 (25%) searched without language restriction. 32/68 (47%) attempted to include unpublished data and 11/68 (16%) assessed for the risk of missing studies quantitatively. The reviews had deficiencies in the assessment of validity of studies and exploration for heterogeneity. When compared to Cochrane reviews, other reviews were significantly inferior in specifying questions (OR 20.3, 95% CI 1.1-381.3, p = 0.04), framing focussed questions (OR 30.9, 95% CI 3.7- 256.2, p = 0.001), use of unpublished data (OR 5.6, 95% CI 1.9-16.4, p = 0.002), assessment for heterogeneity (OR 38.1, 95%CI 2.1, 688.2, p = 0.01) and use of meta-analyses (OR 3.7, 95% CI 1.3-10.8, p = 0.02). CONCLUSION This study identifies areas which have a strong influence on maternal morbidity and mortality but lack good quality systematic reviews. Overall quality of the existing systematic reviews was variable. Cochrane reviews were of better quality as compared to other reviews. There is a need for good quality systematic reviews to inform practice in maternal medicine.

Abstract
BACKGROUND Secondary postpartum haemorrhage is any abnormal or excessive bleeding from the birth canal occurring between 24 hours and 12 weeks postnatally. In developed countries, two per cent of postnatal women are admitted to hospital with this condition, half of them undergoing uterine surgical evacuation; in developing countries it is a major contributor to maternal death. OBJECTIVES To evaluate the relative effectiveness and safety of the treatments used for secondary postpartum haemorrhage. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group trials register (May 2001), the Cochrane Controlled Trials Register (The Cochrane Library, issue 2, 2001), MEDLINE (back to 1966) and EMBASE (back to 1988). The National Research Register was also searched. The reference lists of trial reports and reviews were searched by hand. Where possible, further sources were sought from the first named authors of the papers identified. SELECTION CRITERIA All randomised or quasi randomised comparisons between drug therapies, surgical therapies and placebo or no treatment for the management of secondary postpartum haemorrhage occurring between 24 hours and three months following a pregnancy of at least 24 weeks gestation. DATA COLLECTION AND ANALYSIS Reports of possibly eligible studies were scrutinised by two investigators. The third investigator acted as an advisor/arbitrator. MAIN RESULTS Of the 45 papers identified, none met the inclusion criteria. REVIEWER'S CONCLUSIONS No information is available from randomised controlled trials to inform the management of women with secondary postpartum haemorrhage. This topic may have received little attention because it is perceived as being associated with maternal morbidity rather than mortality in developed countries; it is only recently that the extent and importance of postnatal maternal morbidity has been recognised. A well designed randomised controlled trial comparing the various drug therapies for women with secondary postpartum haemorrhage against each other and against placebo or no treatment groups is needed.
