RESUMEN

INTRODUCTION: Preeclampsia, characterized by hypertensive disorders and systemic inflammatory response, remains a leading cause of maternal morbidity and mortality globally. Effective risk assessment tools are crucial for predicting adverse maternal outcomes. OBJECTIVE: This study evaluates the performance of the fullPIERS (Preeclampsia Integrated Estimate of Risk) model in predicting adverse maternal outcomes within 24 hours of admission for preeclampsia. METHODS: A cross-sectional study was conducted over one year, involving 100 preeclamptic patients admitted to Nil Ratan Sircar Medical College & Hospital (NRSMCH). Predictor variables were collected within 24 hours of admission and analyzed using the fullPIERS model. RESULTS: The fullPIERS model effectively stratified maternal risk. Adverse outcomes were significantly associated with systolic blood pressure (BP) ≥ 140 mmHg, diastolic BP ≥ 90 mmHg, oxygen saturation ≤ 95%, frontal headache, visual disturbances, chest pain/dyspnea, and abnormal random blood sugar, albumin, alanine aminotransferase, platelet count, and creatinine levels. A fullPIERS score ≥ 30 was strongly predictive of adverse maternal outcomes. CONCLUSION: The fullPIERS model is a valuable tool for predicting adverse maternal outcomes in preeclampsia, aiding in timely and effective clinical decision-making.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Gestational diabetes mellitus (GDM) is a growing public health concern that affects many pregnancies globally. The condition is associated with adverse maternal and neonatal outcomes including gestational hypertension, preeclampsia, placental abruption, preterm birth, stillbirth, and fetal growth restriction. In the long-term, mothers and children have an increased risk of developing metabolic diseases such as type 2 diabetes and cardiovascular disease. Accumulating evidence suggest that alterations in the maternal microbiome may play a role in the pathogenesis of GDM and adverse pregnancy outcomes. This review describes changes in the maternal microbiome during the physiological adaptations of pregnancy, GDM and adverse maternal and neonatal outcomes. Findings from this review highlight the importance of understanding the link between the maternal microbiome and GDM. Furthermore, new therapeutic approaches to prevent or better manage GDM are discussed. Further research and clinical trials are necessary to fully realize the therapeutic potential of the maternal microbiome and translate these findings into clinical practice.

RESUMEN

OBJECTIVE: To determine the predictors of adverse maternal and perinatal outcomes among parturients with prolonged second stage of labor. METHODS: This study is a cross-sectional study of women with prolonged second stage of labor from January 1 to June 30, 2021, in four tertiary hospitals in Ethiopia. Data were collected prospectively using a structured questionnaire. Descriptive statistics were used to analyze baseline characteristics. Bivariate and multivariate logistic regression analyses were applied to determine predictors of adverse maternal and perinatal outcomes. RESULTS: A total of 406 women were included in the study. More than half (25/46, 54%) of the women with a prolonged second stage of 4 h or longer had vaginal delivery, which was lower than the 73% (140/190) of women who had a second stage of 2-3 h and the 63.4% (64/101) of women with a second stage duration of 3-4 h. Duration of second stage of labor was not a predictor of composite adverse maternal outcomes nor was it a predictor of adverse perinatal outcome. Operative vaginal delivery (adjusted odds ratio [aOR] 6.0, 95% confidence interval [CI] 2.41-14.9) and nulliparity (aOR 4.1, 95% CI 1.58-10.41) were predictors of adverse maternal outcome, but nulliparity (aOR 1.8, 95% CI 1.05-3.04) and duration of rupture of membranes greater than 18 h (aOR 2.4, 95% CI 1.21-4.93) were predictors of adverse perinatal outcomes. CONCLUSION: Under strict fetal and maternal well-being monitoring, women with a prolonged second stage of labor can labor for an additional 2 h (up to a total of 4 h) without increasing adverse maternal and neonatal outcomes.

RESUMEN

OBJECTIVE: To systematically review and assess the risk of bias in the literature evaluating the performance of INTERGROWTH-21st estimated fetal weight (EFW) standards to predict maternal, fetal and neonatal adverse outcomes. METHODS: Searches were performed in seven electronic databases (Scopus, Web of Science, Medline, Embase, Lilacs, Scielo and Google Scholar) using citation tools and keywords (intergrowth AND (standard OR reference OR formula OR model OR curve); all from 2014 to the last search on April 16th, 2021). We included full-text articles investigating the ability of INTERGROWTH-21st EFW standards to predict maternal, fetal or neonatal adverse outcomes in women with a singleton pregnancy who gave birth to infants with no congenital abnormalities. The study was registered on PROSPERO under the number CRD42020115462. Risk of bias was assessed with a customized instrument based on the CHARMS checklist and composed of 9 domains. Meta-analysis was performed using relative risk (RR [95%CI]) and summary ROC curves on outcomes reported by two or more methodologically homogeneous studies. RESULTS: Sixteen studies evaluating fifteen different outcomes were selected. The risk of bias was high (>50% of studies with high risk) for two domains: blindness of assessment (81.3%) and calibration assessment (93.8%). Considering all the outcomes investigated, for 95% of the results, the specificity was above 73.0%, but the sensitivity was below 64.1%. Pooled results demonstrated a higher RR of neonatal small for gestational age (6.71 [5.51-8.17]), Apgar <7 at 5 min (2.17 [1.48-3.18]), and neonatal intensive care unit admission (2.22 [1.76-2.79]) for fetuses classified <10th percentile when compared to those classified above this limit. The limitation of the study is the absence of heterogeneity exploration or publication bias investigation, whereas no outcomes were evaluated by more than five studies. CONCLUSIONS: The IG-21 EFW standard has low sensitivity and high specificity for adverse events of pregnancy. Classification <10th percentile identifies a high-risk group for developing maternal, fetal and neonatal adverse outcomes, especially neonatal small for gestational age, Apgar <7 at 5 min, and neonatal intensive care unit admission. Future studies should include blind assessment of outcomes, perform calibration analysis with continuous data, and evaluate alternative cutoff points.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Breast cancer is a common type of cancer diagnosed during pregnancy, with increasing incidence over the last years, as more women choose to delay childbearing. Compared to breast cancer in general population, pregnancy-associated breast cancer (PABC) is significantly different in its terms of epidemiology, diagnostic and therapeutic management, while it exhibits particularly aggressive behavior, deriving from its unique molecular and biological profile. Although not fully elucidated, the pathophysiological basis of PABC can be traced back to a combination of hormonal and immune changes during pregnancy, breast involution and altered gene expression. There is considerable controversy in the existing literature about the influence of PABC on pregnancy outcomes, regarding both short- and long-term effects on maternal and fetal/neonatal health. The majority of PABC patients have advanced-stage disease at initial diagnosis and face a significantly poorer prognosis, with decreased survival rates. The most commonly reported adverse obstetrical-fetal events are preterm delivery and prematurity-associated neonatal morbidity, while other neonatal treatment-associated complications might also occur, even when safe therapeutic options are applied during pregnancy. The objective of the present comprehensive review was to summarize current knowledge and up-to-date evidence about the pathophysiological, molecular and biological basis of PABC, as well as its association with adverse maternal, obstetrical, fetal and neonatal outcomes.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVE: To evaluate the association between interpregnancy interval (IPI) and risk for gestational diabetes mellitus (GDM). METHODS: We conducted a retrospective cohort study among singleton, non-anomalous, live birth pregnancies of 5,705,812 pregnant individuals in the United States from 2016 to 2018. We examined IPI of 4-<6 months, 6-11 months, 12-17 months, 24-35 months, 36-47 months, 48-59 months, 60-71 months, and ≥72 months in comparison to the reference interval of 18-23 months in relation to risk for GDM. We used logistic regression to evaluate the association between IPI and risk for GDM. RESULTS: There is a significantly increased risk for GDM associated with IPIs of 6-11 months and 12-17 months compared to the reference of 18-23 months (adjusted Odds Ratio [aOR] 1.05, 95% CI: 1.03-1.07; aOR 1.02, 95% CI: 1.01-1.03). The risk for GDM is greater for longer IPIs (36-47 months aOR 1.10, 95% CI: 1.05-1.08; 48-59 months aOR 1.11, 95% CI: 1.09-1.13; 60-71 months aOR 1.14, 95% CI: 1.12-1.16; ≥72 months aOR 1.31, 95% CI: 1.30-1.33). CONCLUSION: Our findings support the growing evidence that shorter and longer IPI increase the risk of GDM in pregnant individuals. Screening guidelines for detection of GDM may need to be re-evaluated and updated to include longer IPIs (≥36 months) as a risk factor for earlier screening prior to current recommendation of 24 weeks gestational age.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Pyelonephritis, a leading cause of infection during pregnancy, is associated with increased maternal adverse outcomes. Therefore, early recognition and intervention of pyelonephritis are important. Early recognition of pyelonephritis has historically been dependent on fever and costovertebral angle tenderness. However, the reliability of these findings to distinguish women who will develop maternal adverse outcomes is limited. OBJECTIVE: This study aimed to identify clinical variables on presentation that are predictive of maternal adverse outcomes associated with pyelonephritis during pregnancy. STUDY DESIGN: A retrospective cohort study of pregnant women admitted with pyelonephritis at a single hospital from October 1, 2015, to July 31, 2021, was conducted. The primary outcome was a composite maternal adverse outcome consisting of any of the following: maternal intensive care unit admission, surgical intervention, hypotension requiring vasopressors, acute respiratory distress syndrome, pulmonary edema, mechanical ventilation, high-flow nasal cannula, disseminated intravascular coagulation, altered mental status, dialysis, organ failure, venous thromboembolism, or maternal death. Differences in maternal characteristics and clinical signs and symptoms on admission were stratified by the presence or absence of a maternal adverse outcome. Categorical variables were analyzed using the Fisher exact test. Continuous data were analyzed with Wilcoxon rank-sum test. Sensitivity and specificity and likelihood ratios with 95% confidence intervals were calculated for the detection of maternal adverse outcomes by specified admission physical examination and laboratory findings. RESULTS: Of 97 women that met the inclusion criteria, 28 (28.9%) had maternal adverse outcomes. Moreover, 50 of 97 women (51.5%) had fever on presentation, with no difference between cohorts recognized. Admission vital signs were not significantly different between cohorts. Costovertebral angle tenderness was present in 78 of 97 women (80.4%) on presentation, with no difference between cohorts. Compared with women without a maternal adverse outcome, women with maternal adverse outcomes were more likely to have leukocytosis (18/28 [64.3%] vs 20/69 [29.0%]), thrombocytosis (3/28 [10.7%] vs 5/69 [7.2%]), bandemia (8/28 [28.6%] vs 7/69 [10.1%]), and an abnormal serum potassium (20/28 [71.4%] vs 32/63 [50.8%]). CONCLUSION: Admission vital signs may not reliably identify women with pyelonephritis at risk of maternal adverse outcomes. Laboratory studies, particularly a complete blood count and electrolytes, may provide a means of distinguishing those at risk of maternal adverse outcomes.

RESUMEN

OBJECTIVE: To determine whether adjusting for healthcare utilization and comorbidity diagnosed in the year before delivery improves the prediction of adverse maternal outcomes. METHODS: The Truven Health MarketScan database was used to determine whether healthcare utilization and comorbidity diagnosed in the year before pregnancy improved prediction of acute organ injury or death during the delivery hospitalization through 30 days postpartum in this retrospective cohort study. In an initial model, we analyzed the risk for adverse outcomes controlling for underlying comorbidity, obesity, and demographic risk factors present during pregnancy. Subsequent models included diagnoses from the year before pregnancy as well as whether patients had emergency department encounters, inpatient hospitalizations, or received medications from a pharmacy. We compared risk estimates and whether prediction of acute organ injury or death improved with data from the year before pregnancy. Unadjusted and adjusted log-linear regression models were performed to demonstrate the association between exposures and outcomes with unadjusted (RR) and adjusted risk ratios (aRR) with 95% CIs as measures of effects. Logistic regression was performed to calculate the c-statistic of the adjusted models. Separate analyses were performed for patients with Medicaid and commercial insurance. An analysis of Medicaid patients by maternal race and ethnicity was performed to determine if diagnoses and utilization before pregnancy accounted for maternal disparities. RESULTS: A total of 740,002 patients were analyzed in this study. In unadjusted analyses of patients with commercial insurance, ≥2 compared to 0 emergency department encounters (RR = 1.82, 95% CI = 1.61, 2.07), ≥2 compared to 0 inpatient hospitalizations (RR = 4.43, 95% CI = 3.20, 6.13), and receipt of medications from ≥5 prescription groups compared to no prescriptions (RR = 1.97, 95% CI = 1.74, 2.24) were all associated with increased risk for acute organ injury or death. Higher underlying comorbidity and obesity were also associated with increased risk. These risks were attenuated in adjusted analyses but retained significance. Risk estimates were similar for patients with Medicaid insurance with the exception of receipt of medications from ≥5 prescription groups which was non-significant in adjusted analyses (aRR = 1.12, 95% CI = 0.90, 1.40). C-statistics from logistic regression models were similar for models with and without pre-pregnancy data. When race was added to the adjusted models, risk among black women in the adjusted models did not differ significantly from the unadjusted estimate. CONCLUSION: ED encounters and inpatient admissions the year before pregnancy were associated with increased risk of adverse maternal outcomes. However, adding these risk factors to adjusted models did not meaningfully improve the amount of variance accounted for. Further research is indicated to determine to what degree longitudinal care quality is associated with maternal risk.

RESUMEN

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.

RESUMEN

OBJECTIVES: To provide up-to-date data concerning hypertensive disorders of pregnancy on maternal and neonatal profiles in Indonesia. METHODS: Retrospective clinical audit on all pregnancy-associated hypertensive women between 1 January 2020 and 31 March 2020 at Cianjur General District Hospital. RESULTS: Preeclampsia accounts for 66.8% (235/352) of hypertensive disorders of pregnancy, gestational hypertension 29% (102/352) and chronic hypertension 4.3% (15/352). Compared to other pregnant women, those with preeclampsia, on average, had higher systolic and diastolic blood pressures and poorer kidney (ureum and creatinine) and liver function (aspartate transaminase enzyme and alanine transaminase enzyme) profiles (p < 0.001, < 0.001, < 0.001, 0.003, 0.033 and 0.002, respectively), and required more intensive care admission. Neonates from women with severe forms of preeclampsia (eclampsia and HELLP syndrome (haemolysis, elevated liver enzymes, low platelets)) had, on average, lower birthweight (p = 0.015 and 0.048, respectively) and birth length (p = 0.021, 0.017). Neonates from eclamptic mothers had poorer APGAR (appearance, pulse, grimace, activity and respiration) scores (p = 0.006 and 0.005, respectively). CONCLUSION: Hypertensive disorders of pregnancy exerts adverse maternal and neonatal outcomes, particularly among eclampsia and HELLP-syndrome neonates. Various challenges remain for optimal management.
