RESUMO
BACKGROUND: Mothers of advanced age, defined as pregnant women aged ≥ 35 years at the time of giving birth, are traditionally known to be associated with increased risks of adverse maternal outcomes. We determined the prevalence of adverse maternal outcomes and associated factors among mothers of advanced age who delivered at Kabale Regional Referral Hospital (KRRH), in Southwestern Uganda. METHODS: We conducted a cross-sectional study at the Maternity Ward of KRRH from April to September 2023. We consecutively enrolled pregnant women aged ≥ 35 years during their immediate post-delivery period and before discharge. We obtained data on their socio-demographic, obstetric, medical characteristics and their maternal outcomes using interviewer-administered questionnaires. We defined adverse maternal outcome as any complication sustained by the mother that was related to pregnancy, delivery and immediate post-partum events (obstructed labour, antepartum haemorrhage, mode of delivery [cesarean or vacuum extraction], postpartum haemorrhage, hypertensive disorders of pregnancy, preterm or postdate pregnancy, anemia, premature rupture of membranes, multiple pregnancy, and maternal death). A participant was considered to have an adverse outcome if they experienced any one of these complications. We identified factors associated with adverse outcomes using modified Poisson regression. RESULTS: Out of 417 participants, most were aged 35-37 years (n = 206; 49.4%), and had parity ≥ 5 (65.5%). The prevalence of adverse maternal outcomes was 37.6% (n = 157, 95%CI: 33.1-42.4%). Common adverse maternal outcomes included caesarian delivery (23%), and obstructed labour (14.4%). Other complications included anemia in pregnancy (4.5%), chorioamnionitis (4.1%), preterm prelabour rupture of membranes (3.9%), and chronic hypertension and preeclampsia (both 2.4%). Factors associated with adverse maternal outcomes were precipitate labour (adjusted prevalence ratio [aPR] = 1.95, 95%CI: 1.44-2.65), prolonged labour, lasting > 12 h (aPR = 2.86, 95%CI: 1.48-3.16), and chronic hypertension (aPR = 2.01, 95%CI: 1.34-3.9). CONCLUSION: Approximately two-fifth of the advanced-aged mothers surveyed had adverse outcomes. Mothers with prolonged labour, precipitate labour and chronic hypertension were more likely to experience adverse outcomes. We recommend implementation of targeted interventions, emphasizing proper management of labor as well as close monitoring of hypertensive mothers, and those with precipitate or prolonged labor, to mitigate risks of adverse outcomes within this study population.

OBJECTIVE: To determine the relative burdens of maternal and perinatal complications for preterm and term pre-eclampsia. DESIGN: Prospective observational cohort study. SETTING: Two English maternity units. POPULATION: Unselected women with singleton pregnancies who developed pre-eclampsia (International Society for the Study of Hypertension in Pregnancy definition). METHODS: Outcomes were ascertained by health record review and compared between pregnancies with preterm (versus term) pre-eclampsia. MAIN OUTCOME MEASURES: Severe maternal hypertension, maternal mortality or major maternal morbidity, perinatal mortality or major neonatal morbidity, neonatal unit (NNU) admission ≥48 hours, and birthweight <3rd percentile. RESULTS: Among 40 241 singleton pregnancies, 298 (0.7%, 95% confidence interval [CI] 0.66-0.83) and 1194 (3.0%, 95% CI 2.8-3.1) developed preterm and term pre-eclampsia, respectively. Women with preterm (versus term) pre-eclampsia more commonly experienced adverse maternal or perinatal events: severe hypertension 18.5% (95% CI 14.5-23.3) versus 13.6% (95% CI 11.7-15.6); maternal mortality/major morbidity 7.4% (95% CI 4.9-10.9) versus 2.2% (95% CI 1.5-3.2); perinatal mortality/major neonatal morbidity 29.5% (95% CI 24.6-34.9) versus 2.2% (95% CI 1.5-3.2); and birthweight <3rd percentile 54.4% (95% CI 48.7-59.9) versus 14.2% (95% CI 12.4-16.3). However, in absolute terms, most maternal complications occurred in women with term pre-eclampsia, as did a large proportion of perinatal complications: severe hypertension 74.7% (95% CI 68.5-80.0); maternal mortality/major morbidity 54.2% (95% CI 40.3-67.4); perinatal mortality/major neonatal morbidity 22.8% (95% CI 16.1-31.3); NNU admission ≥48 hours 38.1% (95% CI 32.4-44.1); and birthweight <3rd percentile 51.2% (95% CI 45.8-56.5). CONCLUSIONS: Although adverse event risks are greater with preterm (versus term) pre-eclampsia, term disease is associated with at least equivalent total numbers of maternal, and a significant proportion of perinatal, adverse events. Increased efforts should be made to decrease the incidence of term pre-eclampsia.

OBJECTIVES: To assess clinical utility of the urine Congo red dot test (CRDT) in predicting composite adverse maternal and neonatal outcomes in women with suspected preeclampsia (PE). METHODS: CRDT result and pregnancy outcomes were prospectively documented in women with new onset or pre-existing hypertension, new or pre-existing proteinuria, PE symptoms and suspected PE-related fetal growth restriction or abnormal Doppler presenting from 20 weeks' gestation between January 2020 and December 2022. Participants and clinicians were blinded to the CRDT result and managed according to internally agreed protocols. Composite maternal outcome was defined as PE, postpartum hemorrhage, intensive care unit admission, and maternal death. Composite neonatal outcome was defined as small for gestational age, preterm birth, 5-min Apgar score < 7, neonatal intensive care unit admission, and neonatal death. RESULTS: Two hundred and forty-four women out of two hundred and fifty-one (97.2%) had a negative CRDT. All seven women with positive CRDT had both adverse maternal and neonatal outcomes, giving positive predictive values (PPV) of 100%. Rates of composite adverse maternal and neonatal outcomes in CDRT negative women were 103/244 [42.2%, 95% confidence interval (CI) 36.2%-48.5%] and 170/244 (69.7%, 95% CI 63.6%-75.1%), respectively. CRDT negative predictive values (NPV) for adverse maternal and neonatal outcomes were, respectively, 141/244 (57.8%, 95% CI 48.6%-68.2%) and 74/244 (30.3%, 95% CI 23.8%-38.1%). CONCLUSION: CRDT had low NPV but high PPV for adverse maternal and neonatal outcomes in women with suspected PE. Its role in clinical management and triage of women with suspected PE is limited as it cannot identify those at low risk of developing adverse outcomes.
RESUMO
OBJECTIVE: This study aimed to systematically assess the impact of cardiomyopathy on maternal pregnancy outcomes. DATA SOURCES: PubMed, Ovid Embase, Ovid MEDLINE, Cochrane Library, and ClinicalTrials.gov were systematically searched from inception to April 24, 2022. STUDY ELIGIBILITY CRITERIA: Observational cohort, case-control, and case-cohort studies in human populations were included if they reported predefined maternal outcomes for pregnant women with cardiomyopathy (any subtype) and for an appropriate control population (pregnant women with no known heart disease or pregnant women with noncardiomyopathy heart disease). METHODS: Two reviewers independently assessed the articles for eligibility and risk of bias, and conflicts were resolved by a third reviewer. Data were extracted and synthesized according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Meta-Analyses of Observational Studies in Epidemiology guidelines. RESULTS: A total of 14 studies (n=57,539,306 pregnancies) were eligible for inclusion. Women with cardiomyopathy were more likely to deliver by cesarean delivery than women with no heart disease (odds ratio, 2.96; 95% confidence interval, 2.47-3.55; I2=95%; P≤.00001) or women with noncardiomyopathy heart disease (odds ratio, 1.90; 95% confidence interval, 1.62-2.22; I2=91%; P<.00001). Having cardiomyopathy conferred a greater risk for experiencing severe maternal adverse cardiovascular events during pregnancy when compared with not having any heart disease (odds ratio, 206.64; 95% confidence interval, 192.09-222.28; I2=73%; P<.0001) or having noncardiomyopathy heart disease (odds ratio, 7.09; 95% confidence interval; 6.08-8.27; I2=88%; P<.00001). In-hospital mortality was significantly higher among women with cardiomyopathy than among women with no heart disease (odds ratio, 126.67; 95% confidence interval, 43.01-373.07; I2=87%; P<.00001) or among women with noncardiomyopathy heart disease (odds ratio, 4.30; 95% confidence interval, 3.42-5.40; I2=0%; P<.00001). CONCLUSION: Pregnant women with cardiomyopathy have increased risks for adverse maternal outcomes, including maternal death, when compared with both women with no heart disease and women with noncardiomyopathy heart disease. Our results highlight the importance of preconception risk assessments to allow for informed decision-making before pregnancy. Pregnancies affected by cardiomyopathy are high risk and should be managed by expert, multidisciplinary obstetrical and cardiology teams.

BACKGROUND: The risk of venous thromboembolism after delivery is modified by mode of delivery, with the risk of venous thromboembolism being higher after cesarean delivery than vaginal delivery. The risk of venous thromboembolism after peripartum hysterectomy is largely unknown. OBJECTIVE: This study aimed to compare the incidence and risk of venous thromboembolism among women who had and did not have a peripartum hysterectomy. Furthermore, we sought to compare the risk of venous thromboembolism after hysterectomy with other patient, pregnancy, and delivery risk factors known to be associated with venous thromboembolism. STUDY DESIGN: This was a cross-sectional study of women with delivery encounters identified in the Nationwide Readmissions Database from October 2015 to December 2017. Delivery encounters and all variables of interest were identified using the International Classification of Diseases, Tenth Revision diagnosis and procedure codes. The incidence of venous thromboembolism during delivery and rehospitalizations within 6 weeks after discharge was compared among women who had and did not have a peripartum hysterectomy. Multivariable logistic regressions were used to estimate associations between venous thromboembolism and hysterectomy, adjusted for the following characteristics: maternal age, payer at time of delivery, obesity, hypertension, diabetes mellitus, tobacco use, multifetal gestation, peripartum infection, and peripartum hemorrhage. Similarly, venous thromboembolism risk was compared by mode of delivery, including hysterectomy. Diagnoses that may have been indications for peripartum hysterectomy were identified among patients who underwent a hysterectomy and compared between those who did and did not have venous thromboembolism. Analyses used survey weights to obtain population estimates. RESULTS: Of the 4,419,037 women with deliveries, 5098 (11.5 per 10,000 deliveries) underwent a hysterectomy. Moreover, 110 patients (215.8 per 10,000 deliveries) were diagnosed with venous thromboembolism after hysterectomy. The risk of venous thromboembolism was significantly higher in women who underwent a hysterectomy than in women who did not have a hysterectomy (unadjusted odds ratio, 25.1 [95% confidence interval, 20.0-31.5]; adjusted odds ratio, 11.2 [95% confidence interval, 8.7-14.5]; P<.001). Comparing the risk of venous thromboembolism by mode of delivery, the unadjusted and adjusted incidences of venous thromboembolism were 6.9 (95% confidence interval, 6.5-7.3) and 7.4 (95% confidence interval, 6.9-7.8) per 10,000 deliveries among women after vaginal delivery without peripartum hysterectomy, 12.5 (95% confidence interval, 11.8-13.1) and 11.3 (95% confidence interval, 10.7-12.0) per 10,000 deliveries after cesarean delivery without hysterectomy; and 217.2 (95% confidence interval, 169.1-265.2) and 96.9 (95% confidence interval 76.9-126.5) per 10,000 deliveries after hysterectomy, regardless of mode of delivery. Of the 110 diagnoses of venous thromboembolism with peripartum hysterectomy, 89 (81%) occurred during delivery admission. Of the remaining 21 cases, 50% occurred within the first 10 days after discharge from delivery, and 75% occurred within 25 days after discharge. CONCLUSION: These findings have demonstrated that peripartum hysterectomy is associated with a markedly increased risk of venous thromboembolism in the postpartum period, even when controlling for other known risk factors for postpartum thromboembolic events. Here, the incidence of venous thromboembolism after peripartum hysterectomy (2.2%) met some guideline-based risk thresholds for routine thromboprophylaxis, potentially for at least 2 weeks after delivery. Further investigation into the role of routine venous thromboembolism prophylaxis during and after delivery is needed.

BACKGROUND: While maternal sexually transmitted infections (STIs) during pregnancy have been extensively studied, fewer studies have directly compared the associations of different infections and co-infections or investigated the association between STIs in pregnancy and maternal outcomes. OBJECTIVES: We examine associations between STIs and co-infections in pregnancy on risks of adverse neonatal and maternal outcomes. METHODS: Data from the 2019 US natality files (n = 3,747,882) were used to assess the associations between STIs in pregnancy on adverse pregnancy outcomes. Five mutually exclusive STI groups were examined: a single chlamydia, syphilis, or gonorrhoeal infection, chlamydia and gonorrhoea co-infection, and syphilis co-infection (with chlamydia, gonorrhoea, or both). Demographic and obstetric characteristics among each STI group were compared to those of an uninfected comparison group. Prevalence ratios (PR) of adverse neonatal outcomes (preterm birth, small for gestational age [SGA] births, and 5-min APGAR (Appearance, Pulse, Grimace, Activity, and Respiration) score < 7) and maternal outcomes (gestational hypertension) by STI status were examined using log-binomial regression. RESULTS: Increased prevalence of preterm birth was apparent, especially among those with a syphilis infection (PR 1.19, 95% confidence intreval [CI] 1.10, 1.30 for single infections and PR 1.31, 95% CI 1.10, 1.57 for co-infections). All STI groups, except gonorrhoea and chlamydia co-infections, were associated with an increased prevalence of gestational hypertension, with the strongest association among those with syphilis co-infections (PR 1.41, 95% CI 1.13, 1.76). CONCLUSIONS: An increased prevalence was of preterm birth and low APGAR scores were associated with syphilis infection. Increased prevalence of GH among those with STIs warrants further investigation into the relationships and corresponding mechanisms of STIs in pregnancy on adverse maternal outcomes.

BACKGROUND: Coronavirus disease 2019 may be associated with adverse maternal and neonatal outcomes in pregnancy, but there are few controlled data to quantify the magnitude of these risks or to characterize the epidemiology and risk factors. OBJECTIVE: This study aimed to quantify the associations of coronavirus disease 2019 with adverse maternal and neonatal outcomes in pregnancy and to characterize the epidemiology and risk factors. STUDY DESIGN: We performed a matched case-control study of pregnant patients with confirmed coronavirus disease 2019 cases who delivered between 16 and 41 weeks' gestation from March 11 to June 11, 2020. Uninfected pregnant women (controls) were matched to coronavirus disease 2019 cases on a 2:1 ratio based on delivery date. Maternal demographic characteristics, coronavirus disease 2019 symptoms, laboratory evaluations, obstetrical and neonatal outcomes, and clinical management were chart abstracted. The primary outcomes included (1) a composite of adverse maternal outcome, defined as preeclampsia, venous thromboembolism, antepartum admission, maternal intensive care unit admission, need for mechanical ventilation, supplemental oxygen, or maternal death, and (2) a composite of adverse neonatal outcome, defined as respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, 5-minute Apgar score of <5, persistent category 2 fetal heart rate tracing despite intrauterine resuscitation, or neonatal death. To quantify the associations between exposure to mild and severe or critical coronavirus disease 2019 and adverse maternal and neonatal outcomes, unadjusted and adjusted analyses were performed using conditional logistic regression (to account for matching), with matched-pair odds ratio and 95% confidence interval based on 1000 bias-corrected bootstrap resampling as the effect measure. Associations were adjusted for potential confounders. RESULTS: A total of 61 confirmed coronavirus disease 2019 cases were enrolled during the study period (mild disease, n=54 [88.5%]; severe disease, n=6 [9.8%]; critical disease, n=1 [1.6%]). The odds of adverse composite maternal outcome were 3.4 times higher among cases than controls (18.0% vs 8.2%; adjusted odds ratio, 3.4; 95% confidence interval, 1.2-13.4). The odds of adverse composite neonatal outcome were 1.7 times higher in the case group than to the control group (18.0% vs 13.9%; adjusted odds ratio, 1.7; 95% confidence interval, 0.8-4.8). Stratified analyses by disease severity indicated that the morbidity associated with coronavirus disease 2019 in pregnancy was largely driven by the severe or critical disease phenotype. Major risk factors for associated morbidity were black and Hispanic race, advanced maternal age, medical comorbidities, and antepartum admissions related to coronavirus disease 2019. CONCLUSION: Coronavirus disease 2019 during pregnancy is associated with an increased risk of adverse maternal and neonatal outcomes, an association that is primarily driven by morbidity associated with severe or critical coronavirus disease 2019. Black and Hispanic race, obesity, advanced maternal age, medical comorbidities, and antepartum admissions related to coronavirus disease 2019 are risk factors for associated morbidity.

BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) is a major global public health concern. However, there is a dearth of literature on whether MDR-TB and its medications impact maternal and perinatal outcomes, and when such evidence exists the findings are conflicting. OBJECTIVES: This systematic review and meta-analysis aimed to examine the impact of MDR-TB and its medications during pregnancy on maternal and perinatal outcomes. SEARCH STRATEGY: PubMed, Scopus and Web of Science databases were searched from earliest to February 2020. SELECTION CRITERIA: Records were screened based on pre-defined selection criteria and assessed for quality by two independent reviewers. DATA COLLECTION AND ANALYSIS: A meta-analysis was performed using the random effects model to calculate pooled prevalence for each outcome. MAIN RESULTS: Of the 72 records identified, 12 were included in the systematic review and meta-analysis, consisting of 174 pregnant women with MDR-TB and 110 adverse outcomes. Maternal death, pregnancy loss, preterm birth and low birthweight were the most common maternal and perinatal adverse outcomes reported in the studies. The overall pooled prevalence was 7.5% (95% CI 3.2-12.8) for maternal death, 10.6% (95% CI 6.0-16.3) for pregnancy loss, 12.9% (95% CI 0.0-38.0) for preterm birth and 23.7% (95% CI 17.0-31.0) for low birthweight. CONCLUSIONS: The findings suggest that MDR-TB is associated with a high risk of adverse maternal and perinatal outcomes, but these should be interpreted cautiously because the evidence is largely preliminary. Adequately powered prospective cohort studies are urgently required to corroborate these findings. TWEETABLE ABSTRACT: Multidrug-resistant tuberculosis may increase the risk of adverse maternal and perinatal outcomes.

BACKGROUND: The incidence of eclampsia and its adverse maternal outcomes are very high in developing countries, particularly in Subsaharan African Countries. Identifying predictors for adverse maternal outcomes of eclampsia has paramount importance for helping health care providers to optimize their management outcomes. Therefore, this study aimed to assess the incidence of adverse maternal outcomes of eclampsia and its determinant factors. METHODS: A retrospective follow-up study design was applied. The data were extracted from patient charts using a structured, pre-tested, questionnaire. Descriptive analyses (frequencies, means, and standard deviation) were calculated, and bi-variable and multivariable logistic regression models were used to testing the association between independent variables and an outcome variable. After the data were coded and entered into Epi-Info Version 7.2 Software, the data were analyzed using STATA Version 14 Statistical Software. RESULTS: The magnitude of eclampsia was 5.36 per 1000 pregnancies (95% CI: 4.72, 6.10). The incidence of adverse maternal outcomes in eclamptic mothers was 53.7% (95% CI: 47.02, 60.24%). After adjusting for covariates maternal age 30-34, AOR 5.4 [95% CI = 1.02, 28.6]; age above 34, AOR 10.5 [95% CI = 1.3, 88.6]; gravidity 2-4, AOR 0.3 [95% CI = 0.1, 0.9]; 10 or more convulsions, AOR 4.6 [95% CI = 1.4, 14.9]; mild pyrexia, AOR 20.4 [95% CI = 3.7, 112.7]; moderate pyrexia, AOR 14.6 [95% CI = 1.7125.1]; platelet count below 50,000 cells/mm3, AOR 34.9 [95% CI = 3.6, 336.2]; platelet count between 50,000 and 99,000 cells/mm3, AOR 24.5 [95%CI = 5.4111.6]; and stillbirth of the current pregnancy, AOR 23.2 [95%CI = 2.1257.5] were strong predictors of adverse maternal outcomes in eclamptic mothers. CONCLUSIONS: The incidence of adverse maternal outcomes of eclampsia was found to be high compared to similar studies discussed in this study. This study recommends early identification of patients with the risk factors (having many convulsions, high body temperature, low platelet count, patient age above 30 years, and 2-4 pregnancies), strengthening the referral system, and advocation of research on the area of adverse maternal outcomes and thereby encourage evidence-based medicine.

This review aimed to examine the existing evidence about interventions proposed for the treatment of clinical chorioamnionitis, with the goal of developing an evidence-based contemporary approach for the management of this condition. Most trials that assessed the use of antibiotics in clinical chorioamnionitis included patients with a gestational age of ≥34 weeks and in labor. The first-line antimicrobial regimen for the treatment of clinical chorioamnionitis is ampicillin combined with gentamicin, which should be initiated during the intrapartum period. In the event of a cesarean delivery, patients should receive clindamycin at the time of umbilical cord clamping. The administration of additional antibiotic therapy does not appear to be necessary after vaginal or cesarean delivery. However, if postdelivery antibiotics are prescribed, there is support for the administration of an additional dose. Patients can receive antipyretic agents, mainly acetaminophen, even though there is no clear evidence of their benefits. Current evidence suggests that the administration of antenatal corticosteroids for fetal lung maturation and of magnesium sulfate for fetal neuroprotection to patients with clinical chorioamnionitis between 24 0/7 and 33 6/7 weeks of gestation, and possibly between 23 0/7 and 23 6/7 weeks of gestation, has an overall beneficial effect on the infant. However, delivery should not be delayed to complete the full course of corticosteroids and magnesium sulfate. Once the diagnosis of clinical chorioamnionitis has been established, delivery should be considered, regardless of the gestational age. Vaginal delivery is the safer option and cesarean delivery should be reserved for standard obstetrical indications. The time interval between the diagnosis of clinical chorioamnionitis and delivery is not related to most adverse maternal and neonatal outcomes. Patients may require a higher dose of oxytocin to achieve adequate uterine activity or greater uterine activity to effect a given change in cervical dilation. The benefit of using continuous electronic fetal heart rate monitoring in these patients is unclear. We identified the following promising interventions for the management of clinical chorioamnionitis: (1) an antibiotic regimen including ceftriaxone, clarithromycin, and metronidazole that provides coverage against the most commonly identified microorganisms in patients with clinical chorioamnionitis; (2) vaginal cleansing with antiseptic solutions before cesarean delivery with the aim of decreasing the risk of endometritis and, possibly, postoperative wound infection; and (3) antenatal administration of N-acetylcysteine, an antioxidant and antiinflammatory agent, to reduce neonatal morbidity and mortality. Well-powered randomized controlled trials are needed to assess these interventions in patients with clinical chorioamnionitis.

INTRODUCTION: A previously developed Obstetric Comorbidity Index has been validated in highly selected cohorts. Validation of the index in an unselected population as well as in other health registers is, however, of high importance to determine external validity. MATERIAL AND METHODS: Using nationwide registers, we formed a nationwide cohort including completed pregnancies (both live- and stillborn) in Denmark from 2000 through 2014. Maternal age and 20 comorbid conditions were assessed and weighted. Outcomes were maternal end-organ injury or death within 30 days postpartum. The index's predictive and discriminative ability was estimated by Brier score and the area under the receiver operating characteristic curve (AUC), respectively. Logistic regression analysis was used to estimate odds ratios (OR) with 95% confidence interval (CI). RESULTS: In 876 496 completed pregnancies by 527 079 women, 1.40% (n = 12 314) experienced an outcome. The majority of women (64.1%) did not have any record of a condition included in the index and only 0.3% (n = 3044) had a score >6. The incidence of an outcome increased with increasing comorbidity score from 0.9% (95% CI 0.8-0.9) in women scoring 0% to 10.4% (95% CI 7.6-13.9) in women scoring 9-10. Compared with women scoring 0, a score of 1-2 yielded an OR of 2.34 (95% CI 2.25-2.44), 3-4 an OR of 5.16 (95% CI 4.81-5.54), 5-6 an OR of 4.84 (95% CI 4.31-5.44), and 8-9 an OR of 7.97 (95% CI 6.54-9.72) for experiencing the outcome. The index had a Brier score of 0.01 and an AUC of 0.64. CONCLUSIONS: Despite potential weaknesses in the outcome definition, the Obstetric Comorbidity Index showed a moderate ability to discriminate and predict end-organ injury and death in a nationwide cohort in Denmark, in accordance with previous findings. These results suggest that the index may be a useful tool to control for confounding in health research and clinically to identify women at high risk for adverse maternal outcomes.

High-risk obstetric patients have chances of deterioration which can be detected by any early warning score. This study was aimed to assess the suitability of the Obstetrics National Early Warning System (ONEWS) for the pregnant women. This prospective study was conducted on 500 high-risk pregnant women attending a tertiary care teaching hospital. The ONEWS charts were plotted for each of them. The primary outcome measure was composite adverse maternal outcome (CAMO) in the form of one or more among mortality, severe maternal morbidity and intensive care unit admissions. Of the 500 women who participated, 200 (40%) had a score ≥3 (triggered an intervention). The CAMO among the triggered group [59.5% (n=119)] was significantly higher compared to that in the non-triggered group [13.3% (n=40) (P=0.001)]. The area under the receiver operating characteristic curve was 0.800 (95% confidence interval 0.752-0.847). The sensitivity of the ONEWS in predicting CAMO was 74.8 per cent, specificity 76.2 per cent, positive predictive value 59.5 per cent and negative predictive value 86.7 per cent at a cut-off score of 3. ONEWS appears to be a useful tool for predicting adverse maternal outcomes in high-risk pregnant women.

BACKGROUND: For low risk women, there is good evidence that planned birth in a midwifery unit is associated with a reduced risk of maternal interventions compared with planned birth in an obstetric unit. Findings from the Birthplace cohort study have been interpreted by some as suggesting a reduced risk of interventions in planned births in freestanding midwifery units (FMUs) compared with planned births in alongside midwifery units (AMUs). However, possible differences have not been robustly investigated using individual-level Birthplace data. METHODS: This was a secondary analysis of data on 'low risk' women with singleton, term, 'booked' pregnancies collected in the Birthplace national prospective cohort study. We used logistic regression to compare interventions and outcomes by parity in 11,265 planned FMU births and 16,673 planned AMU births, adjusted for potential confounders, using planned AMU birth as the reference group. Outcomes considered included adverse perinatal outcomes (Birthplace primary outcome measure), instrumental delivery, intrapartum caesarean section, 'straightforward vaginal birth', third or fourth degree perineal trauma, blood transfusion and maternal admission for higher-level care. We used a significance level of 1% for all secondary outcomes. RESULTS: There was no significant difference in adverse perinatal outcomes between planned AMU and FMU births. The odds of instrumental delivery were reduced in planned FMU births (nulliparous: aOR 0.63, 99% CI 0.46-0.86; multiparous: aOR 0.41, 99% CI 0.25-0.68) and the odds of having a 'straightforward vaginal birth' were increased in planned FMU births compared with planned AMU births (nulliparous: aOR 1.47, 99% CI 1.17-1.85; multiparous: 1.86, 99% CI 1.35-2.57). The odds of intrapartum caesarean section did not differ significantly between the two settings (nulliparous: p = 0.147; multiparous: p = 0.224). The overall pattern of findings suggested a trend towards lower intervention rates and fewer adverse maternal outcomes in planned FMU births compared with planned AMU births. CONCLUSIONS: The findings support the recommendation that 'low risk' women can be informed that planned birth in an FMU is associated with a lower rate of instrumental delivery and a higher rate of 'straightforward vaginal birth' compared with planned birth in an AMU; and that outcomes for babies do not appear to differ between FMUs and AMUs.

OBJECTIVE: To explore and compare perinatal and maternal outcomes in women at 'higher risk' of complications planning home versus obstetric unit (OU) birth. DESIGN: Prospective cohort study. SETTING: OUs and planned home births in England. POPULATION: 8180 'higher risk' women in the Birthplace cohort. METHODS: We used Poisson regression to calculate relative risks adjusted for maternal characteristics. Sensitivity analyses explored possible effects of differences in risk between groups and alternative outcome measures. MAIN OUTCOME MEASURES: Composite perinatal outcome measure encompassing 'intrapartum related mortality and morbidity' (intrapartum stillbirth, early neonatal death, neonatal encephalopathy, meconium aspiration syndrome, brachial plexus injury, fractured humerus or clavicle) and neonatal admission within 48 hours for more than 48 hours. Two composite maternal outcome measures capturing intrapartum interventions/adverse maternal outcomes and straightforward birth. RESULTS: The risk of 'intrapartum related mortality and morbidity' or neonatal admission for more than 48 hours was lower in planned home births than planned OU births [adjusted relative risks (RR) 0.50, 95% CI 0.31-0.81]. Adjustment for clinical risk factors did not materially affect this finding. The direction of effect was reversed for the more restricted outcome measure 'intrapartum related mortality and morbidity' (RR adjusted for parity 1.92, 95% CI 0.97-3.80). Maternal interventions were lower in planned home births. CONCLUSIONS: The babies of 'higher risk' women who plan birth in an OU appear more likely to be admitted to neonatal care than those whose mothers plan birth at home, but it is unclear if this reflects a real difference in morbidity. Rates of intrapartum related morbidity and mortality did not differ statistically significantly between settings at the 5% level but a larger study would be required to rule out a clinically important difference between the groups.

OBJECTIVES: To evaluate the impact of maternal BMI on intrapartum interventions and adverse outcomes that may influence choice of planned birth setting in healthy women without additional risk factors. DESIGN: Prospective cohort study. SETTING: Stratified random sample of English obstetric units. SAMPLE: 17,230 women without medical or obstetric risk factors other than obesity. METHODS: Multivariable log Poisson regression was used to evaluate the effect of BMI on risk of intrapartum interventions and adverse maternal and perinatal outcomes adjusted for maternal characteristics. MAIN OUTCOME MEASURES: Maternal intervention or adverse outcomes requiring obstetric care (composite of: augmentation, instrumental delivery, intrapartum caesarean section, general anaesthesia, blood transfusion, 3rd/4th degree perineal tear); neonatal unit admission or perinatal death. RESULTS: In otherwise healthy women, obesity was associated with an increased risk of augmentation, intrapartum caesarean section and some adverse maternal outcomes but when interventions and outcomes requiring obstetric care were considered together, the magnitude of the increased risk was modest (adjusted RR 1.12, 95% CI 1.02-1.23, for BMI > 35 kg/m(2) relative to low risk women of normal weight). Nulliparous low risk women of normal weight had higher absolute risks and were more likely to require obstetric intervention or care than otherwise healthy multiparous women with BMI > 35 kg/m(2) (maternal composite outcome: 53% versus 21%). The perinatal composite outcome exhibited a similar pattern. CONCLUSIONS: Otherwise healthy multiparous obese women may have lower intrapartum risks than previously appreciated. BMI should be considered in conjunction with parity when assessing the potential risks associated with birth in non-obstetric unit settings.

INTRODUCTION: Many female teenagers in low-resource settings conceive, of which half are unplanned and end in many deaths in sub-Saharan Africa, accounting for the majority of the cases. Teenage pregnancy is associated sometimes with poor maternal, newborn, and child deaths. OBJECTIVES: The aim of the study was to determine the prevalence, maternal obstetric outcomes, and factors associated with poor maternal obstetric outcomes among teenage mothers delivering at Mbarara Regional Referral Hospital. METHODS: This was a cross-sectional study carried out in a maternity ward at Mbarara Regional Referral Hospital, where 9,200 mothers deliver annually. All the women coming in for the delivery of their babies were consecutively approached for inclusion in the study. The women were enrolled in the post-delivery ward after delivery and interviewed with pretested questionnaires to capture the sociodemographic, obstetric, and medical profiles of the mothers. Factors were significant if the p-value was <0.05. Results: Out of the 327 participants, the majority were rural dwellers (68.5%), married (75.8%), attained primary education (69.4%), had not used contraception (89%), and had had a planned pregnancy (63.3%). The prevalence of adverse maternal obstetrical events was 59.9%. The HIV-positive rate was 4.9%, and about half of the participants had delivered by cesarean section (41.6%). The participants' mean age was 18.4 years and SD 1.1. The mean number of antenatal care contacts attended was 4.59 and SD 1.9. The adverse maternal outcomes included episiotomy (30.9%), perineal tear (18.7%), premature rupture of membranes (10.1%), placenta abruption (5.2%), and pre-eclampsia/eclampsia (4%). Having a cesarean delivery was found to significantly reduce the occurrence of adverse maternal obstetric events among the participants by 97% (adjusted odds ratio (aOR) (95% CI) of 0.03 (0.02-0.06), p-value<0.001). Having a prior history of a miscarriage was significantly associated with the occurrence of adverse maternal obstetrical events among the participants (aOR (95% CI) of 6.55 (1.46-29.42), p-value0.014). CONCLUSIONS: Slightly more than half of the teenage mothers had adverse maternal obstetrical outcomes, and a history of a miscarriage in previous pregnancies was significantly associated with adverse maternal obstetrical outcomes. Having a cesarean delivery was found to significantly reduce the occurrence of adverse maternal obstetric events among the participants. Teenage mothers are at a high risk of adverse maternal obstetrical outcomes, and close antepartum and intrapartum surveillance is recommended.
RESUMO
BACKGROUND AND AIMS: Stimulant-related disorders (SRD), or the continued misuse of illicit or prescribed stimulants, during pregnancy can have adverse health effects for mothers and infants. This study aimed to measure prevalence and trends of SRD diagnosis in pregnancy, and associations between SRD diagnosis and adverse maternal and infant health outcomes, among pregnant individuals in California. DESIGN: Retrospective cohort study. SETTING: California, USA. PARTICIPANTS: Pregnant individuals from the Study of Outcomes in Mothers and Infants (SOMI) with singleton live births between 2012 and 2020 (n = 3 740 079). MEASUREMENTS: SRD diagnosis (excluding cocaine) and maternal (gestational diabetes, gestational hypertension [gHTN], severe maternal morbidity [SMM]) and infant (very preterm birth [gestational age <32 weeks], preterm birth [gestational age 32-37 weeks], neonatal intensive care unit [NICU] admission, small for gestational age [SGA]) outcomes were classified using International Classification of Disease (ICD) codes and vital statistics. Risk ratios were estimated with modified Poisson log linear regression that accounted for sibling pregnancies. Covariates included maternal sociodemographic characteristics, mental and physical health problems, nicotine use and co-occurrence of other diagnosed substance use disorders. Bias analyses were conducted to address unmeasured confounding and exposure misclassification. FINDINGS: SRD diagnosis among pregnant individuals increased from 2012 to 2020 (554 to 748 per 100 000 births). SRD diagnosis was associated with an increased risk of SMM (adjusted risk ratio [aRR] = 2.3; 95% confidence interval [CI] = 2.2-2.5), gHTN (aRR = 1.8; 95% CI = 1.7-1.9), very preterm birth (aRR = 2.2, 95% CI = 2.0-2.5), preterm birth (aRR = 2.1, 95% CI = 2.1-2.2) and NICU admission (aRR = 2.0, 95%CI = 1.9-2.0), and a decreased risk of gestational diabetes (aRR = 0.8; 95% CI = 0.8-0.9). SRD diagnosis was not associated with infants born SGA. Findings were generally robust to unmeasured confounding and misclassification of diagnosis. CONCLUSIONS: Stimulant-related disorder diagnosis during pregnancy appears to be associated with an increased risk for select adverse maternal and infant health outcomes including severe maternal morbidity, gestational hypertension, very preterm birth, preterm birth and neonatal intensive care unit admission.
RESUMO
Information on the effect of bloody amniotic fluid during labor at term is scarce. This study assessed risk factors and adverse outcomes in labors with bloody amniotic fluid. During the six years of this study, all nulliparas in our institution, with a trial of labor, were included. Multiple pregnancies and preterm deliveries were excluded. Outcomes were compared between the bloody amniotic fluid group and the clear amniotic fluid group. Overall, 11,252 women were included. Among them, 364 (3.2%) had bloody amniotic fluid and 10,888 (96.7%) had clear amniotic fluid. Women in the bloody amniotic fluid group were characterized by shorter duration of the second stage and higher rate of cesarean section due to non-reassuring fetal heart rate. In addition, there were higher rates of low cord pH (<7.1) and NICU admissions in the bloody amniotic fluid group. In multivariate logistic regression analysis, cesarean delivery, cord blood pH < 7.1, and NICU admission were independently associated with increased odds ratio for bloody amniotic fluid. Bloody amniotic fluid at term is associated with adverse outcomes and must be considered during labor.
RESUMO
Background: The relationship between physical comorbidities and postpartum hospital readmission is well studied, with less research regarding the impact of mental health conditions on postpartum readmission. Methods: Using hospital discharge data (2016-2019) from the Hospital Cost and Utilization Project Nationwide Readmissions Database (n = 12,222,654 weighted), we evaluated the impact of mental health conditions (0, 1, 2, and ≥3), as well as five individual conditions (anxiety, depressive, bipolar, schizophrenic, and traumatic/stress-related conditions) on readmission within 42 days, 1-7 days ("early"), and 8-42 days ("late") of hospitalization for birth. Results: In adjusted analyses, the rate of 42-day readmission was 2.2 times higher for individuals with ≥3 mental health conditions compared to those with none (3.38% vs. 1.56%; p < 0.001), 50% higher among individuals with 2 mental health conditions (2.33%; p < 0.001), and 40% higher among individuals with 1 mental health condition (2.17%; p < 0.001). We found increased adjusted risk of 42-day readmission for individuals with anxiety (1.98% vs. 1.59%; p < 0.001), bipolar (2.38% vs. 1.60%; p < 0.001), depressive (1.93% vs. 1.60%; p < 0.001), schizophrenic (4.00% vs. 1.61%; p < 0.001), and traumatic/stress-related conditions (2.21% vs. 1.61%; p < 0.001), relative to individuals without the respective condition. Mental health conditions had larger impacts on late (8-42 day) relative to early (1-7 day) readmission. Conclusions: This study found strong relationships between mental health conditions during the hospitalization for birth and readmission within 42 days. Efforts to reduce the high rates of adverse perinatal outcomes in the United States should continue to address the impact of mental health conditions during pregnancy and throughout the postpartum period.

OBJECTIVE: To evaluate the association between fetal head position during prevacuum assessment and adverse outcomes. METHOD: This retrospective cohort study included all vacuum-assisted deliveries using the Kiwi Omnicup over 5 years. Primary outcomes were third- or fourth-degree perineal tear, pH < 7.1, and subgaleal hematoma (SGH). AGAR, neonatal intensive care unit admission, cephalohematoma, Erb's palsy, third-stage duration, and postpartum hemorrhage were secondary. Outcomes were compared between the occiput posterior (OP) and occiput anterior (OA) positions. RESULTS: The study included 1960 patients. OP position was more likely to involve epidural analgesia (311 [82.5%] vs. 1216 [77%], P = 0.020), higher fetal head station (P = 0.001), higher percentage of cup detachments (121 cases [32.1%] vs. 307 [19.4%], P = 0.001), and longer procedure (5.5 ± 3.7 min vs. 4.7 ± 2.8 min, P = 0.001). OP was associated with umbilical cord pH < 7.1 (21 [5.5%] vs. 52 [3.9%], P = 0.032), NICU admissions (16 [4.2%] vs. 38 [2.4%], P = 0.049), SGH (18 [4.8%] vs. 38 [2.4%], P = 0.013), and high-degree perineal tears (12 [3.2%] vs. 26 [1.7%], with borderline significance, P = 0.051). SGH and high-grade tears remained significantly associated with OP position (P = 0.008 and P = 0.016, respectively) after adjusting for maternal age, nulliparity, diabetes, epidural anesthesia, preprocedure head station, and birth weight. CONCLUSION: OP position is an independent risk-factor for anal sphincter injury and SGH during vacuum-assisted delivery.
