Pregnancy-induced changes to the gut microbiota drive macrophage pyroptosis and exacerbate septic inflammation. Immunity 2023; 56:336-352.e9. [PMID: 36792573 DOI: 10.1016/j.immuni.2023.01.015] [Citation(s) in RCA: 25] [Impact Index Per Article: 25.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Revised: 09/18/2022] [Accepted: 01/13/2023] [Indexed: 02/16/2023]
Abstract
The physiological and immune changes that occur during pregnancy are associated with worsened disease outcomes during infection and sepsis. How these perturbations exacerbate inflammation has not been explored. Here, using antibiotic treatment and fecal microbial transfers, we showed that sepsis susceptibility is driven by pregnancy-induced changes to gut microbiome in mice and humans. Integrative multiomics and genetically engineered bacteria revealed that reduced Parabacteroides merdae (P. merdae) abundance during pregnancy led to decreased formononetin (FMN) and increased macrophage death. Mechanistically, FMN inhibited macrophage pyroptosis by suppressing nuclear accumulation of hnRNPUL2 and subsequent binding to the Nlrp3 promoter. Treatment with FMN or deletion of murine hnRNPUL2 protected against septic inflammation. Intestinal abundances of P. merdae and FMN inversely correlated with the progression of septic patients. Our data reveal a microbe-immune axis that is disrupted in pregnant septic hosts, highlighting the potential of the FMN-hnRNPUL2-NLRP3 axis in providing promising therapeutic strategies for sepsis.

Maternal Sepsis in Italy: A Prospective, Population-Based Cohort and Nested Case-Control Study. Microorganisms 2022; 11:microorganisms11010105. [PMID: 36677397 PMCID: PMC9865500 DOI: 10.3390/microorganisms11010105] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 12/21/2022] [Accepted: 12/28/2022] [Indexed: 01/04/2023] Open
Abstract
Maternal sepsis represents a leading cause of mortality and severe morbidity worldwide. In Italy, it is the second cause of direct maternal mortality. Delay in recognition and treatment initiation are the drivers of sepsis-associated adverse outcomes. Between November 2017 and October 2019, the Italian Obstetric Surveillance System coordinated a prospective population-based study on maternal sepsis occurring before or after childbirth from 22 weeks' gestation onward and up to 42 days following the end of pregnancy. A nested 1:2 matched case-control study on postpartum sepsis was also performed. Maternal sepsis was diagnosed for the presence of suspected or confirmed infection alongside signs or symptoms of organ failure. The aim of this study was to assess maternal sepsis incidence and its associated risk factors, management, and perinatal outcomes. Six Italian regions, covering 48.2% of the national births, participated in the project. We identified an incidence rate of 5.5 per 10,000 maternities (95% CI 4.80-6.28). Seventy percent of patients had a low education level and one third were foreigners with a language barrier. Genital, respiratory, and urinary tract infections were the predominant sources of infection; the majority of cases was caused by E. coli and polymicrobial infections. The presence of vascular and indwelling bladder catheters was associated with a nine-fold increased risk of postpartum sepsis. There were no maternal deaths, but one fourth of women experienced a serious adverse event and 28.3% required intensive care; 1.8% of newborns died. Targeted interventions to increase awareness of maternal sepsis and its risk factors and management should be promoted.

Abstract
Background Sepsis is a very serious complication of cesarean section, understanding the influencing factors is important to the prevention and management of sepsis. We aimed to analyze the associated risk factors of sepsis of cesarean section, to provide evidences into the clinical management and nursing care of cesarean section. Methods Patients who underwent cesarean section surgery from January 1, 2017 to June 30, 2021 in our hospital were included. The characteristics of patients were collected and analyzed. Logistic regression analyses were conducted to analyze the influencing factors of sepsis of cesarean section. Results A total of 3819 patients undergoing cesarean section were included, the incidence of sepsis in patients undergoing cesarean section was 0.84%. There were significant differences in the age, vaginal delivery attempt, premature rupture of membranes, preoperative hemoglobin, estimated blood loss during surgery and postoperative urinary tube implacement between sepsis and no sepsis patients (all p < 0.05). Logistic regression analyses found that age ≥ 35y(OR3.22, 95%CI1.20 ~ 5.15), gestational diabetes(OR2.64, 95%CI1.91 ~ 4.15), vaginal delivery attempt(OR2.05, 95%CI1.70 ~ 4.42), premature rupture of membranes(OR2.42, 95%CI1.02 ~ 4.20), preoperative hemoglobin ≤ 105 g/L(OR4.39, 95%CI1.02 ~ 7.88), estimated blood loss during surgery ≥ 400 ml(OR1.81, 95%CI1.35 ~ 3.01), postoperative urinary tube implacement(OR2.19, 95%CI1.27 ~ 2.50) were the risk factors of sepsis in patients undergoing cesarean section(all p < 0.05). Escherichia Coli(46.15%), Enterococcus faecalis(17.95%) and Pseudomonas aeruginosa(12.83%) were the most commonly-seen bacteria in sepsis patients. Conclusion In clinical practice, medical workers should carry out strict management and early prevention of related risk factors during the perioperative period of pregnant women, to effectively reduce the occurrence of sepsis after cesarean section.

Short-lived sensitization of cardiovascular outcomes of postpartum endotoxemia in preeclamptic rats: Role of medullary solitary tract neuroinflammation. Eur J Pharmacol 2021; 910:174494.

Abstract
Preeclampsia (PE) is a pregnancy-related disorder with serious maternal complications. Considering the increased importance of postpartum infection in maternal morbidity and mortality, we investigated whether preeclamptic maternal programming alters cardiovascular consequences of endotoxemia in rats and the role of cardiac and brainstem neuroinflammation in this interaction. Preeclampsia was induced by oral administration of L-NAME (50 mg/kg/day) for 7 days starting from day 14 of conception. Changes in blood pressure, heart rate, and cardiac autonomic function caused by lipopolysaccharide (LPS, 5 mg/kg i.v.) were assessed in mothers at 3 weeks (weaning time) and 9 weeks postnatally. Compared with respective non-PE counterparts, LPS treatment of weaning PE mothers caused significantly greater (i) falls in blood pressure, (ii) rises in heart rate and left ventricular contractility (dP/dtmax), (iii) reductions in time and frequency domain indices of heart rate variability and shifts in cardiac sympathovagal balance (low-frequency/high-frequency ratio, LF/HF) towards parasympathetic dominance, and (iv) attenuation of reflex bradycardic responses measured by the vasoactive method. The intensified LPS effects in weaning PE rats subsided after 9 weeks of delivery. Immunohistochemical studies showed increased protein expression of nuclear factor kappa B (NF-κB) in brainstem neuronal pools of the nucleus of the solitary tract (NTS), but not rostral ventrolateral medulla (RVLM), in endotoxic PE weaning rats compared with non-PE rats. Cardiac NF-κB expression was increased by LPS but this was similarly noted in PE and non-PE rats. Together, preeclamptic maternal programming elicits short-term exacerbation of endotoxic cardiovascular and autonomic derangements due possibly to exaggerated NTS neuroinflammatory insult.

Abstract
OBJECTIVE Sepsis is a life-threatening syndrome caused by the body's response to infection. The Global Maternal Sepsis Study (GLOSS) suggests sepsis plays a larger role in maternal morbidity and mortality than previously thought. We therefore sought to compare national and international guidelines for maternal sepsis to determine their consistency with each other and the Third International Consensus for Sepsis and Septic Shock (SEPSIS-3). STUDY DESIGN Using Cochrane Database of Systematic Reviews, PubMed, Google Scholar, and organization Web sites, we identified seven guidelines on maternal sepsis in the English language-The American College of Obstetricians and Gynecologists, Society for Maternal-Fetal Medicine, Royal Australian and New Zealand College of Obstetricians and Gynaecologists, Society of Obstetric Medicine of Australia and New Zealand, Royal College of Obstetricians and Gynaecologists, Royal College of Physicians of Ireland Institute of Obstetricians and Gynaecologists, and World Health Organization. Guidelines were reviewed to ascertain the commonality and variation, if any, in definitions of maternal sepsis, tools and criteria utilized for diagnosis, obstetric warning systems used, as well as evaluation and management of maternal sepsis. These variables were also compared with SEPSIS-3. RESULTS All guidelines provided definitions consistent with a version of the SEPSIS, although the specific version utilized were varied. Clinical variables and tools employed for diagnosis of maternal sepsis were also varied. Evaluation and management of maternal sepsis and septic shock were similar. CONCLUSION In conclusion, national and international maternal sepsis guidelines were incongruent with each other and SEPSIS-3 in diagnostic criteria and tools but similar in evaluation and management recommendations. KEY POINTS · Definitions for maternal sepsis and septic shock are varied.. · Maternal sepsis guidelines differ in proposed criteria and tools.. · Maternal sepsis guidelines have similar management recommendations..

Abstract
PURPOSE OF REVIEW Maternal sepsis is the second leading cause of maternal death in the United States. A significant number of these deaths are preventable and the purpose of this review is to highlight causes such as delays in recognition and early treatment. RECENT FINDINGS Maternal sepsis can be difficult to diagnose due to significant overlap of symptoms and signs of normal physiological changes of pregnancy, and current screening tools perform poorly to identify sepsis in pregnant women. Surveillance should not only include during pregnancy, but also throughout the postpartum period, up to 42 days postpartum. Education and awareness to highlight this importance are not only vital for obstetric healthcare provides, but also for nonobstetric healthcare providers, patients, and support persons. SUMMARY Through education and continual review and analysis of evidence-based practice, a reduction in maternal morbidity and mortality secondary to maternal sepsis should be attainable with dedication from all disciplines that care for obstetric and postpartum patients. Education and vigilance also extend to patients and support persons who should be empowered to escalate care when needed.

Abstract
La sepsis se reconoce como una enfermedad común y mortal, cuya epidemiología obliga al médico tratante a realizar un diagnóstico oportuno por el alto riesgo de complicaciones o muerte. En las gestantes hay una gran vulnerabilidad debido a los cambios físicos y hormonales que están afrontado. Es indispensable iniciar el tratamiento tan pronto se tenga el diagnóstico, para evitar que sea mortal tanto para la madre como para el feto. Es por esto que el objetivo es una revisión sobre la intervención en las pacientes con diagnóstico de sepsis en estado de embarazo al ingreso a la UCI, bajo los siguientes ejes temáticos: definición clara de sepsis en el embarazo, factores de riesgo, intervención terapéutica en UCI y consecuencias para el feto durante su intervención. Se concluye que el manejo de la sepsis en las embarazadas es muy similar a las que no lo están. Hacen falta investigaciones con evidencia científica, velando siempre por la vida ya que no solo se trata un ser humano sino de dos.

Abstract
Group A Streptococcus (GAS) infections result in a considerable underappreciated burden of acute and chronic disease globally. A 2018 World Health Assembly resolution calls for better control and prevention. Providing guidance on global health research needs is an important World Health Organization (WHO) activity, influencing prioritization of investments. Here, the role, status, and directions in GAS vaccines research are discussed. WHO preferred product characteristics and a research and development technology roadmap, briefly presented, offer an actionable framework for vaccine development to regulatory and policy decision making, availability, and use. GAS vaccines should be considered for global prevention of the range of clinical manifestations and associated antibiotic use. Impediments related to antigen diversity, safety concerns, and the difficulty to establish vaccine efficacy against rheumatic heart disease are discussed. Demonstration of vaccine efficacy against pharyngitis and skin infections constitutes a key near-term strategic goal. Investments and collaborative partnerships to diversify and advance vaccine candidates are needed.

Abstract
BACKGROUND An awareness campaign set to accompany the Global Maternal Sepsis Study (GLOSS) was launched in 2017. In order to better develop and evaluate the campaign, we sought to understand the factors that influence awareness of maternal sepsis by exploring healthcare providers' knowledge, perception of enabling environments, and perception of severity of maternal sepsis. METHODS We used a mixed-methods approach that included 13 semi-structured interviews to GLOSS regional and country coordinators and 1555 surveys of providers working in GLOSS participating facilities. Directed content analysis and grounded theory were used for qualitative analysis, based on a framework including four overarching themes around maternal health conditions, determinants of maternal health, barriers and facilitators to sepsis identification and management, plus 24 additional sub-topics that emerged during the interviews. Descriptive statistics for frequencies and percentages were used for the quantitative analysis; significance was tested using Pearson χ2. Logistic regressions were performed to adjust for selected variables. RESULTS Analysis of interviews described limited availability of resources, poor quality of care, insufficient training and lack of protocols as some of the barriers to maternal sepsis identification and management. Analysis from the quantitative survey showed that while 92% of respondents had heard of maternal sepsis only 15% were able to correctly define it and 43% to correctly identify initial management. Provider confidence, perceived availability of resources and of a supportive environment were low (33%, 38%, and 48% respectively). Overall, the predictor that most explained awareness was training. Respondents from the survey and interviewees identified sepsis among the main conditions affecting women at their facilities. CONCLUSIONS Awareness on maternal sepsis, while acknowledged as important, remains low. Healthcare providers need resources and support to feel confident about the correct identification and management of sepsis, as a prerequisite for the improvement of awareness of maternal sepsis. Similarly, providers need to know about maternal sepsis and its severity to understand the importance of reducing sepsis-related mortality and morbidity. Awareness raising campaigns can help bring neglected maternal health conditions, such as sepsis, to the forefront of global and local agendas.

Abstract
OBJECTIVE To analyze quality improvement opportunities (QIOs) identified through review of cases of maternal death from sepsis by the California Pregnancy-Associated Mortality Review Committee. DESIGN Qualitative descriptive design using thematic analysis. SAMPLE A total of 118 QIOs identified from 27 cases of pregnancy-related deaths from sepsis in California from 2002 to 2007. METHODS We coded and thematically organized the 118 QIOs using three of the four domains commonly applied in quality improvement initiatives for maternal health care: Readiness, Recognition, and Response. Data did not include reporting issues, so the Reporting domain was excluded from the analysis. RESULTS Women's delay in seeking care was the central theme in the Readiness domain. In the Recognition domain, health care providers missed the signs and symptoms of sepsis, including elevated temperature, elevated white blood cell count, increased heart rate, decreased blood pressure, mottled skin, preterm labor, headache, and pain. For Response, late antibiotic administration was a central theme; multiple emergent themes included administration of the wrong antibiotics, failure to investigate women's complaints of pain, lack of nurse/provider communication, and lack of follow-up care after hospital discharge. CONCLUSION To reverse the contribution of sepsis to the rising rate of maternal mortality in the United States, health care facilities and providers need to reduce barriers for women who seek care, recognize early symptoms, and respond with appropriate treatment. This could be achieved by implementation of the Maternal Early Warning Criteria, standardized guidelines such as those from the Surviving Sepsis campaign, and comprehensive discharge education.

Abstract
OBJECTIVE To examine the microbiology and associated antibiotic resistance patterns among febrile peripartum women with positive blood cultures. METHODS We conducted a retrospective cohort study in which we reviewed all bacteremia cases between 2009 and 2016 that occurred between 7 days before and 30 days after delivery. Institutional guidelines include obtaining blood cultures and promptly initiating intravenous antibiotics for all obstetric patients with fever of 100.4°F or higher. We describe antibiotic resistance patterns for the most frequently isolated organisms and perform univariate analyses regarding maternal and neonatal outcomes based on type of bacteremia. RESULTS Among 56,835 deliveries, 3,797 (6.7%) obstetric patients had blood cultures drawn and 120 (3.2%) had documented bacteremia. The most commonly cultured organisms were Escherichia coli (17.5%, n=21), Bacteroides species (10.8%, n=13), Enterococcus species (10.8%, n=13), group B streptococci (10.8%, n=13), and group A streptococci (5.0%, n=6). E coli had high rates of resistance to ampicillin (n=17, 81.0%) and extended spectrum beta lactams (n=10, 47.6%). Gram-positive bacteremia was noted in 65/120 patients (54.2%), gram-negative bacteremia in 39/120 (32.5%), and anaerobic bacteremia in 16/120 (13.3%) (P=.02). Neonatal bacteremia was identified in 8/120 cases (6.7%), of which 7/8 (87.5%) were attributable to gram-negative bacteria and 1/8 (12.5%) were attributable to gram-positive bacteremia (P=.004). There were no differences in neonatal death or maternal intensive care unit admission. CONCLUSION Peripartum bacteremia is uncommon, with the most frequently isolated organism being E coli. The evolution of antibiotic resistance patterns in E coli at our institution may be of clinical significance in determining antibiotic choice for peripartum fever.

Abstract
Background Prophylactic antibiotics are commonly prescribed intra-operatively after caesarean section birth, often at high doses. Even so, wound infections are not uncommon and obesity increases the risk. Currently, no independent wound assessment technology is available to stratify women to low or high risk of surgical site infection (SSI).Study Aim: to investigate the potential of non-invasive infrared thermography (IRT), performed at short times after surgery, to predict later SSI. Methods IRT was undertaken in hospital on day 2 with community follow up (days 7, 15, 30) after surgery. Thermal maps of wound site and abdomen were accompanied by digital photographs, the latter used for wound assessment by six experienced healthcare professionals. Confirmatory diagnosis of SSI was made on the basis of antibiotic prescribing by the woman's community physician with logistic regression models derived to model dichotomous outcomes. Results Fifty-three women aged 21-44 years with BMI 30.1-43.9 Kg.m- 2 were recruited. SSI rate (within 30 days) was 28%. Inter-rater variability for 'professional' opinion of wound appearance showed poor levels of agreement. Two regions of interest were interrogated; wound site and abdomen. Wound site temperature was consistently elevated (1.5 °C) above abdominal temperature with similar values at days 2,7,15 in those who did and did not, develop SSI. Mean abdominal temperature was lower in women who subsequently developed SSI; significantly so at day 7. A unit (1 °C) reduction in abdominal temperature was associated with a 3-fold raised odds of infection. The difference between the sites (wound minus abdomen temperature) was significantly associated with odds of infection; with a 1 °C widening in temperature associated with an odds ratio for SSI of 2.25 (day 2) and 2.5 (day 7). Correct predictions for wound outcome using logistic regression models ranged from 70 to 79%. Conclusions IRT imaging of wound and abdomen in obese women undergoing c-section improves upon visual (subjective) wound assessment. The proportion of cases correctly classified using the wound-abdominal temperature differences holds promise for precision and performance of IRT as an independent SSI prognostic tool and future technology to aid decision making in antibiotic prescribing.

Abstract
During the past decade, there has been an increase in the awareness of infections associated with pregnancy and delivery. The most significant cause of post-partum infection is caesarean section; 20-25% of operations are followed by wound infections, endometritis or urinary tract infections. Approximately 13% of women in the UK undergo operative vaginal delivery (OVD) with forceps or vacuum, which is also associated with an increased risk of infection, estimated at 0.7%-16% of these deliveries. Despite this, previous reviews have identified only one small trial of antibiotic prophylaxis in 393 women and concluded that there was insufficient evidence to support the routine use of prophylactic antibiotics after OVD. The ANODE trial, a multicentre, blinded, placebo-controlled trial from the UK, is due to report findings from more than 3400 women in 2019 and will be the largest study to date of antibiotic prophylaxis following OVD.

Abstract
Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Sepsis can be caused by a broad range of pathogens; however, bacterial infections represent the majority of sepsis cases. Up to 42% of sepsis presentations are culture negative, suggesting a non-bacterial cause. Despite this, diagnosis of viral sepsis remains very rare. Almost any virus can cause sepsis in vulnerable patients (e.g., neonates, infants, and other immunosuppressed groups). The prevalence of viral sepsis is not known, nor is there enough information to make an accurate estimate. The initial standard of care for all cases of sepsis, even those that are subsequently proven to be culture negative, is the immediate use of broad-spectrum antibiotics. In the absence of definite diagnostic criteria for viral sepsis, or at least to exclude bacterial sepsis, this inevitably leads to unnecessary antimicrobial use, with associated consequences for antimicrobial resistance, effects on the host microbiome and excess healthcare costs. It is important to understand non-bacterial causes of sepsis so that inappropriate treatment can be minimised, and appropriate treatments can be developed to improve outcomes. In this review, we summarise what is known about viral sepsis, its most common causes, and how the immune responses to severe viral infections can contribute to sepsis. We also discuss strategies to improve our understanding of viral sepsis, and ways we can integrate this new information into effective treatment.

Abstract
Background Maternal sepsis is the underlying cause of 11% of all maternal deaths and a significant contributor to many deaths attributed to other underlying conditions. The effective prevention, early identification and adequate management of maternal and neonatal infections and sepsis can contribute to reducing the burden of infection as an underlying and contributing cause of morbidity and mortality. The objectives of the Global Maternal Sepsis Study (GLOSS) include: the development and validation of identification criteria for possible severe maternal infection and maternal sepsis; assessment of the frequency of use of a core set of practices recommended for prevention, early identification and management of maternal sepsis; further understanding of mother-to-child transmission of bacterial infection; assessment of the level of awareness about maternal and neonatal sepsis among health care providers; and establishment of a network of health care facilities to implement quality improvement strategies for better identification and management of maternal and early neonatal sepsis. Methods This is a facility-based, prospective, one-week inception cohort study. This study will be implemented in health care facilities located in pre-specified geographical areas of participating countries across the WHO regions of Africa, Americas, Eastern Mediterranean, Europe, South East Asia, and Western Pacific. During a seven-day period, all women admitted to or already hospitalised in participating facilities with suspected or confirmed infection during any stage of pregnancy through the 42nd day after abortion or childbirth will be included in the study. Included women will be followed during their stay in the facilities until hospital discharge, death or transfer to another health facility. The maximum intra-hospital follow-up period will be 42 days. Discussion GLOSS will provide a set of actionable criteria for identification of women with possible severe maternal infection and maternal sepsis. This study will provide data on the frequency of maternal sepsis and uptake of effective diagnostic and therapeutic interventions in obstetrics in different hospitals and countries. We will also be able to explore links between interventions and maternal and perinatal outcomes and identify priority areas for action.

Abstract
Objective Although their rates are decreasing, pregnancy-related mortality and morbidity are problems worldwide. In this study, we aimed to review the characteristics, diagnoses, required interventions and outcomes of obstetric patients admitted between 2006 and 2014 to the Intensive Care Unit (ICU) of a tertiary university hospital to provide an indicator for improving the management of critically ill obstetric patients. Methods A retrospective study of hospital records of obstetric admissions to the ICU was conducted. Results The pregnancy-related ICU admission rate was 0.21% among all deliveries during the study period. Nine antepartum (mean gestational age: 23 weeks) and 48 postpartum (mean gestational age: 34 weeks) obstetric ICU admissions were included. Most obstetric patients admitted antepartum were primiparous (88.8%), whereas those admitted postpartum were multiparous (64.6%). The mean ICU stay was 7 days among the patients admitted antepartum and 6 days among those admitted postpartum. Common medical reasons for ICU admission were respiratory failure and HELLP syndrome in both groups; DIC and eclampsia were also medical reasons causing ICU admission among the postpartum patients. Mechanical ventilation and blood derivative transfusion were the most common interventions required during the ICU stay of the obstetric patients. Maternal death was unique to the patients admitted postpartum (6 patients, 12.5%). Conclusion We reviewed obstetric admissions to our institution over an 8-year period. We believe that a nationwide study in Turkey that provides an indicator of the frequency, reasons of ICU admission and outcome of obstetric patients is required to improve the quality of intensive care.

Abstract
Background There is a need for a clear and actionable definition of maternal sepsis, in order to better assess the burden of this condition, trigger timely and effective treatment and allow comparisons across facilities and countries. The objective of this study was to review maternal sepsis definitions and identification criteria and to report on the results of an expert consultation to develop a new international definition of maternal sepsis. Methods All original and review articles and WHO documents, as well as clinical guidelines providing definitions and/or identification criteria of maternal sepsis were included. A multidisciplinary international panel of experts was surveyed through an online consultation in March-April 2016 on their opinion on the existing sepsis definitions, including new definition of sepsis proposed for the adult population (2016 Third International Consensus Definitions for Sepsis and Septic Shock) and importance of different criteria for identification of maternal sepsis. The definition was agreed using an iterative process in an expert face-to-face consensus development meeting convened by WHO and Jhpiego. Results Standardizing the definition of maternal sepsis and aligning it with the current understanding of sepsis in the adult population was considered a mandatory step to improve the assessment of the burden of maternal sepsis by the expert panel. The literature review and expert consultation resulted in a new WHO consensus definition “Maternal sepsis is a life-threatening condition defined as organ dysfunction resulting from infection during pregnancy, child-birth, post-abortion, or post-partum period”. Plans are in progress to validate the new WHO definition of maternal sepsis in a large international population. Conclusion The operationalization of the new maternal sepsis definition requires generation of a set of practical criteria to identify women with sepsis. These criteria should enable clinicians to focus on the timely initiation of actionable elements of care (administration of antimicrobials and fluids, support of vital organ functions, and referral) and improve maternal outcomes.

Abstract
In addition to immediate implications for pregnancy complications, increasing evidence implicates maternal obesity as a major determinant of offspring health during childhood and later adult life. Observational studies provide evidence for effects of maternal obesity on her offspring's risks of obesity, coronary heart disease, stroke, type 2 diabetes, and asthma. Maternal obesity could also lead to poorer cognitive performance and increased risk of neurodevelopmental disorders, including cerebral palsy. Preliminary evidence suggests potential implications for immune and infectious-disease-related outcomes. Insights from experimental studies support causal effects of maternal obesity on offspring outcomes, which are mediated at least partly through changes in epigenetic processes, such as alterations in DNA methylation, and perhaps through alterations in the gut microbiome. Although the offspring of obese women who lose weight before pregnancy have a reduced risk of obesity, few controlled intervention studies have been done in which maternal obesity is reversed and the consequences for offspring have been examined. Because the long-term effects of maternal obesity could have profound public health implications, there is an urgent need for studies on causality, underlying mechanisms, and effective interventions to reverse the epidemic of obesity in women of childbearing age and to mitigate consequences for offspring.

Abstract
BackgroundStudies of maternal mortality have been shown to result in important improvements to women’s health. It is now recognised that in countries such as the UK, where maternal deaths are rare, the study of near-miss severe maternal morbidity provides additional information to aid disease prevention, treatment and service provision.ObjectivesTo (1) estimate the incidence of specific near-miss morbidities; (2) assess the contribution of existing risk factors to incidence; (3) describe different interventions and their impact on outcomes and costs; (4) identify any groups in which outcomes differ; (5) investigate factors associated with maternal death; (6) compare an external confidential enquiry or a local review approach for investigating quality of care for affected women; and (7) assess the longer-term impacts.MethodsMixed quantitative and qualitative methods including primary national observational studies, database analyses, surveys and case studies overseen by a user advisory group.SettingMaternity units in all four countries of the UK.ParticipantsWomen with near-miss maternal morbidities, their partners and comparison women without severe morbidity.Main outcome measuresThe incidence, risk factors, management and outcomes of uterine rupture, placenta accreta, haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome, severe sepsis, amniotic fluid embolism and pregnancy at advanced maternal age (≥ 48 years at completion of pregnancy); factors associated with progression from severe morbidity to death; associations between severe maternal morbidity and ethnicity and socioeconomic status; lessons for care identified by local and external review; economic evaluation of interventions for management of postpartum haemorrhage (PPH); women’s experiences of near-miss maternal morbidity; long-term outcomes; and models of maternity care commissioned through experience-led and standard approaches.ResultsWomen and their partners reported long-term impacts of near-miss maternal morbidities on their physical and mental health. Older maternal age and caesarean delivery are associated with severe maternal morbidity in both current and future pregnancies. Antibiotic prescription for pregnant or postpartum women with suspected infection does not necessarily prevent progression to severe sepsis, which may be rapidly progressive. Delay in delivery, of up to 48 hours, may be safely undertaken in women with HELLP syndrome in whom there is no fetal compromise. Uterine compression sutures are a cost-effective second-line therapy for PPH. Medical comorbidities are associated with a fivefold increase in the odds of maternal death from direct pregnancy complications. External reviews identified more specific clinical messages for care than local reviews. Experience-led commissioning may be used as a way to commission maternity services.LimitationsThis programme used observational studies, some with limited sample size, and the possibility of uncontrolled confounding cannot be excluded.ConclusionsImplementation of the findings of this research could prevent both future severe pregnancy complications as well as improving the outcome of pregnancy for women. One of the clearest findings relates to the population of women with other medical and mental health problems in pregnancy and their risk of severe morbidity. Further research into models of pre-pregnancy, pregnancy and postnatal care is clearly needed.FundingThe National Institute for Health Research Programme Grants for Applied Research programme.

Abstract
Although septic shock is rare in pregnancy, it is an important contributor to maternal mortality. A woman in the perinatal period can appear deceptively well before rapidly deteriorating to septic shock. We evaluated compliance with early goal-directed therapy before, during, and after the implementation of a standardized physician order set and interprofessional education. A retrospective study included 97 women with positive screening results for sepsis from April 2014 to January 2015. When comparing preintervention and postintervention results in women with sepsis, statistical significance was achieved for blood lactate level testing (p = .029), administering a broad-spectrum antibiotic (p = .006), repeat lactate level testing (p = .034), and administering a broad-spectrum antibiotic in women with severe sepsis and septic shock (p = .010). Education and a sepsis protocol using a multidisciplinary approach improves compliance with sepsis bundles, which are a group of interventions that, when used together, are intended to improve health outcomes.

Abstract
Background Detailed local case review is commonly used as a strategy to improve care. However, recent reports have highlighted concerns over quality of local reviews in maternity care. The aim of this project was to describe the methods used for conducting local reviews of care of women with severe maternal morbidity, and to compare lessons identified for future care through external and local reviews. Methods Thirty-three anonymised clinical records from women with severe maternal morbidities were obtained, together with the report of the local review of their care. The methodology used for the local reviews was described, including specific tools used, team members involved, their disciplines, report format and whether an action plan with recommendations for audit was produced. Multidisciplinary external reviewers considered the records using a standard confidential enquiry approach. A thematic analysis of lessons learned from the two approaches was undertaken. Results A formal report of the local review was produced for 11/33 cases; 4 of these used root cause analysis. A further 12 local reviews consisted of a group discussion with output noted in a spreadsheet; 5 consisted of a timeline with good practice points and 5 had no formal review. Patients were involved in five local reviews; only one was multidisciplinary. Action plans were recorded in 14 local reviews; 3 of these included a recommendation to audit the proposed changes. External reviews identified additional messages for care and highlighted aspects of good care in every case, whereas only 55% (n=18) of local reviews identified good care (p<0.0005). Conclusions The quality of local reviews can clearly be improved. Very few of the reviews involved patients. Local reviews should be multidisciplinary, generate an action plan, and the implementation of recommendations should be audited. Improvements in local reviews may be achieved by standardised training or development of national protocols.

Clinical chorioamnionitis at term V: umbilical cord plasma cytokine profile in the context of a systemic maternal inflammatory response. J Perinat Med 2016; 44:53-76.

Abstract
OBJECTIVE Microbial invasion of the fetus due to intra-amniotic infection can lead to a systemic inflammatory response characterized by elevated concentrations of cytokines in the umbilical cord plasma/serum. Clinical chorioamnionitis represents the maternal syndrome often associated with intra-amniotic infection, although other causes of this syndrome have been recently described. The objective of this study was to characterize the umbilical cord plasma cytokine profile in neonates born to mothers with clinical chorioamnionitis at term, according to the presence or absence of bacteria and/or intra-amniotic inflammation. MATERIALS AND METHODS A cross-sectional study was conducted, including patients with clinical chorioamnionitis at term (n=38; cases) and those with spontaneous term labor without clinical chorioamnionitis (n=77; controls). Women with clinical chorioamnionitis were classified according to the results of amniotic fluid culture, broad-range polymerase chain reaction coupled with electrospray ionization mass spectrometry (PCR/ESI-MS) and amniotic fluid interleukin (IL)-6 concentration into three groups: 1) no intra-amniotic inflammation; 2) intra-amniotic inflammation without detectable microorganisms; or 3) microbial-associated intra-amniotic inflammation. A fetal inflammatory response syndrome (FIRS) was defined as an umbilical cord plasma IL-6 concentration >11 pg/mL. The umbilical cord plasma concentrations of 29 cytokines were determined with sensitive and specific V-PLEX immunoassays. Nonparametric statistical methods were used for analysis, adjusting for a false discovery rate of 5%. RESULTS 1) Neonates born to mothers with clinical chorioamnionitis at term (considered in toto) had significantly higher median umbilical cord plasma concentrations of IL-6, IL-12p70, IL-16, IL-13, IL-4, IL-10 and IL-8, but significantly lower interferon gamma (IFN-γ) and tumor necrosis factor alpha (TNF)-α concentrations than neonates born to mothers with spontaneous term labor without clinical chorioamnionitis; 2) neonates born to mothers with clinical chorioamnionitis at term but without intra-amniotic inflammation had higher concentrations of IL-6, IL-12p70, IL-13, IL-4, IL-5, and IL-8, but lower IFN-γ, than neonates not exposed to clinical chorioamnionitis, suggesting that maternal fever in the absence of intra-amniotic inflammation leads to a change in the fetal cytokine network; 3) there were significant, positive correlations between maternal and umbilical cord plasma IL-6 and IL-8 concentrations (IL-6: Spearman correlation=0.53; P<0.001; IL-8: Spearman correlation=0.42; P<0.001), consistent with placental transfer of cytokines; 4) an elevated fetal plasma IL-6 (>11 pg/mL), the diagnostic criterion for FIRS, was present in 21% of cases (8/38), and all these neonates were born to mothers with proven intra-amniotic infection; and 5) FIRS was associated with a high concentration of umbilical cord plasma IL-8, IL-10 and monocyte chemoattractant protein (MCP)-1. CONCLUSIONS Neonates born to mothers with clinical chorioamnionitis at term had higher concentrations of umbilical cord plasma cytokines than those born to mothers without clinical chorioamnionitis. Even neonates exposed to clinical chorioamnionitis but not to intra-amniotic inflammation had elevated concentrations of multiple cytokines, suggesting that intrapartum fever alters the fetal immune response.

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 To estimate the incidence of severe maternal sepsis due to group B Streptococcus (GBS) in the UK, and to investigate the associated outcomes for mother and infant. DESIGN National case-control study. SETTING All UK consultant-led maternity units. PARTICIPANTS 30 women with confirmed or suspected severe GBS sepsis, and 757 control women. MAIN OUTCOME MEASURES Disease incidence, additional maternal morbidity, critical care admission, length of stay, infant infection, mortality. RESULTS The incidences of confirmed and presumed severe maternal GBS sepsis were 1.00 and 2.75 per 100,000 maternities, respectively, giving an overall incidence of 3.75 per 100,000. Compared with controls, severe GBS sepsis was associated with higher odds of additional maternal morbidity (OR 12.35, 95% CI 3.96 to 35.0), requiring level 2 (OR 39.3, 95% CI 16.0 to 99.3) or level 3 (OR 182, 95% CI 21.0 to 8701) care and longer hospital stay (median stay in cases and controls was 7 days (range 3-29 days) and 2 days (range 0-16 days), respectively, p<0.001). None of the women died. Severe maternal GBS sepsis was associated with higher odds of infant sepsis (OR 32.7, 95% CI 8.99 to 119.0); 79% of infants, however, did not develop sepsis. There were no associated stillbirths or neonatal deaths. CONCLUSIONS Severe maternal GBS sepsis is a rare occurrence in the UK. It is associated with adverse maternal and neonatal outcomes.

Modified obstetric early warning scoring systems (MOEWS): validating the diagnostic performance for severe sepsis in women with chorioamnionitis. Am J Obstet Gynecol 2015; 212:536.e1-8.

Abstract
OBJECTIVE We sought to compare the predictive power of published modified obstetric early warning scoring systems (MOEWS) for the development of severe sepsis in women with chorioamnionitis. STUDY DESIGN This was a retrospective cohort study using prospectively collected clinical observations at a single tertiary unit (Chicago, IL). Hospital databases and patient records were searched to identify and verify cases with clinically diagnosed chorioamnionitis during the study period (June 2006 through November 2007). Vital sign data (heart rate, respiratory rate, blood pressure, temperature, mental state) for these cases were extracted from an electronic database and the single worst composite recording was identified for analysis. Global literature databases were searched (2014) to identify examples of MOEWS. Scores for each identified MOEWS were derived from each set of vital sign recordings during the presentation with chorioamnionitis. The performance of these MOEWS (the primary outcome) was then analyzed and compared using their sensitivity, specificity, positive and negative predictive values, and receiver-operating characteristic curve for severe sepsis. RESULTS Six MOEWS were identified. There was wide variation in design and pathophysiological thresholds used for clinical alerts. In all, 913 women with chorioamnionitis were identified from the clinical database. In all, 364 cases with complete data for all physiological indicators were included in analysis. Five women developed severe sepsis, including 1 woman who died. The sensitivities of the MOEWS in predicting the severe deterioration ranged from 40-100% and the specificities varied even more ranging from 4-97%. The positive predictive values were low for all MOEWS ranging from <2-15%. The MOEWS with simpler designs tended to be more sensitive, whereas the more complex MOEWS were more specific, but failed to identify some of the women who developed severe sepsis. CONCLUSION Currently used MOEWS vary widely in terms of alert thresholds, format, and accuracy. Most MOEWS have not been validated. The MOEWS generally performed poorly in predicting severe sepsis in obstetric patients; in general severe sepsis was overdetected. Simple MOEWS with high sensitivity followed with more specific secondary testing is likely to be the best way forward. Further research is required to develop early warning systems for use in this setting.

Abstract
Background Maternity care is recognised as a particularly high-risk speciality that is subject to investigation and inquiry, and improvements in risk management have been recommended. However, the quality of guidelines for local reviews of maternity incidents is unknown. The aim of the study is to appraise the quality of local guidance on conducting reviews of severe maternity incidents in the National Health Service. Methods Guidelines for incident reviews were requested from all 211 consultant-led maternity units in the UK during 2012. The Appraisal of Guidelines for Research and Evaluation Instrument (AGREE II) was used to evaluate the quality of guidelines. The methods used for reviewing an incident, the people involved in the review and the methods for disseminating the outcomes of the reviews were also examined. Results Guidelines covering 148 (70%) of all NHS maternity units in the UK were received for evaluation. Most guidelines (55%) received were of good or high quality. The median score on ‘scope and purpose’ (86%), concerned with the aims and target population of the guideline, was higher than for other domains. Median scores were: ‘stakeholder involvement’ (representation of users’ views) 56%, ‘rigour of development’ (process used to develop guideline) 34%, ‘clarity of presentation’ 78%, ‘applicability’ (organisational and cost implications of applying guideline) 56% and ‘editorial independence’ 0%. Most guidelines (81%) recommended a range of health professionals review serious maternity incidents using root cause analysis. Findings were most often disseminated at meetings, in reports and in newsletters. Many guidelines (69%) stated lessons learnt from incidents would be audited. Conclusions Overall, local guidance for the review of maternity incidents was mostly of good or high quality. Stakeholder participation in guideline development could be widened, and editorial independence more clearly stated. It was unclear in over a quarter of guidelines whether changes in practice in response to review recommendations were audited or monitored; such auditing should be mandatory. Further research is required to examine the translation of guidance into practice by evaluating the quality of local reviews of maternity incidents.

Abstract
Background and Aims: Admission to an intensive care unit (ICU) is considered as an objective marker of severe maternal morbidity. The aim was to assess the incidence and possible risk factors of obstetric patient admissions in the multidisciplinary ICU of a tertiary care center with emphasis on standardized mortality ratio (SMR). Material and Methods: A retrospective five year ICU record analysis was done for all pregnant women, who were admitted to multidisciplinary ICU of a tertiary care hospital during June 2007-12. Results: During this 5-year period, 21,943 deliveries took place and 164 women required ICU admission. Out of these, the data of 151 patients were analyzed. Maternal mortality rate was 31.1% (47 deaths) for patients admitted to ICU. The simplified acute physiologic score (SAPS) II was 62 (55-68) in nonsurvivor versus 34.00 (28-46) in survivor group (P value < 0.001). The receiver operated characteristic curve was plotted using SAPS II scores and the area under the curve was 0.93 with 95% confidence interval (0.89-0.96). The calculated SMR was 0.97. Conclusions: Women admitted to ICU with diagnosis of puerperal sepsis and intrauterine death (IUD) with coexisting sepsis had higher mortality as compared to women with hypertensive disease of pregnancy and hemorrhage. The calculated SMR was less than one which is a predictor of good ICU care.

Abstract
Despite the acquisition of a large body of evidence, there are many unanswered questions about sepsis. The definition of this disease is plagued by the lack of a simple pathophysiological description linking cause to effect and the activation of host immune responses that hinders disease progression at the same time producing multiorgan dysfunction. A plethora of inconsistent clinical features has served to obfuscate rather than illuminate. The Surviving Sepsis Guidelines (SSG) are a major advance because it comprehensively interrogates all aspects of care for the critically ill. For vulnerable populations living in low- and middle-income countries, this guideline is ineffectual because of the lack of region-specific data, differences in etiology of sepsis and burden of disease, limited human capacity and infrastructure, as well as socioeconomic realities. Appropriate care must be guided by common sense guidelines that are sensitive to local realities and adapted as relevant data are acquired.

Abstract
BACKGROUND In light of increasing rates and severity of sepsis worldwide, this study aimed to estimate the incidence of, and describe the causative organisms, sources of infection, and risk factors for, severe maternal sepsis in the UK. METHODS AND FINDINGS A prospective case-control study included 365 confirmed cases of severe maternal sepsis and 757 controls from all UK obstetrician-led maternity units from June 1, 2011, to May 31, 2012. Incidence of severe sepsis was 4.7 (95% CI 4.2-5.2) per 10,000 maternities; 71 (19.5%) women developed septic shock; and five (1.4%) women died. Genital tract infection (31.0%) and the organism Escherichia coli (21.1%) were most common. Women had significantly increased adjusted odds ratios (aORs) of severe sepsis if they were black or other ethnic minority (aOR = 1.82; 95% CI 1.82-2.51), were primiparous (aOR = 1.60; 95% CI 1.17-2.20), had a pre-existing medical problem (aOR = 1.40; 95% CI 1.01-1.94), had febrile illness or were taking antibiotics in the 2 wk prior to presentation (aOR = 12.07; 95% CI 8.11-17.97), or had an operative vaginal delivery (aOR = 2.49; 95% CI 1.32-4.70), pre-labour cesarean (aOR = 3.83; 95% CI 2.24-6.56), or cesarean after labour onset (aOR = 8.06; 95% CI 4.65-13.97). Median time between delivery and sepsis was 3 d (interquartile range = 1-7 d). Multiple pregnancy (aOR = 5.75; 95% CI 1.54-21.45) and infection with group A streptococcus (aOR = 4.84; 2.17-10.78) were associated with progression to septic shock; for 16 (50%) women with a group A streptococcal infection there was <2 h-and for 24 (75%) women, <9 h-between the first sign of systemic inflammatory response syndrome and a diagnosis of severe sepsis. A limitation of this study was the proportion of women with sepsis without an identified organism or infection source (16.4%). CONCLUSIONS For each maternal sepsis death, approximately 50 women have life-threatening morbidity from sepsis. Follow-up to ensure infection is eradicated is important. The rapid progression to severe sepsis highlights the importance of following the international Surviving Sepsis Campaign guideline of early administration of high-dose intravenous antibiotics within 1 h of admission to hospital for anyone with suspected sepsis. Signs of severe sepsis in peripartum women, particularly with confirmed or suspected group A streptococcal infection, should be regarded as an obstetric emergency.
