Association of the humoral immune response with the inflammatory profile in Plasmodium vivax infections in pregnant women.

Plasmodium vivax infection, when it occurs during pregnancy, has often been associated with serious adverse pregnancy outcomes. However, immunological alterations in pregnancy and their consequences have been little explored. We characterized the humoral immune response in pregnant women exposed to malaria by P. vivax antigens and its association with the maternal inflammatory profile and poor pregnancy outcomes. An observational cohort study in the Brazilian Amazon was conducted between 2013 and 2015. After applying exclusion criteria, 242 mother-child pairs were included in the analysis. Data on maternal infection, gestational outcomes, and inflammatory factors were evaluated in the maternal peripheral plasma. In samples from the first infection, the presence of total IgG and its subclasses in plasma against PvMSP119 protein were also quantified. Previous exposure to malaria, observed by anti-total IgG antibodies to the PvMSP119 antigen, increased the inflammatory response to infection when the pregnant woman had malaria during pregnancy. IL-6 and IL-10 levels were positively correlated with parasitemia and with total IgG levels; but they were negatively correlated with the gestational age at delivery from Pv-infected woman. In multivariate linear regression analyses, IgG 1, 2 and 4 was negatively and positively associated with cytokines IL-6 and IL-10, respectively, in P. vivax-infection. An association between the humoral immune response and the peripheral inflammatory cytokine profile with the adverse outcomes in malaria in pregnancy by P. vivax was observed. Previous exposure to the parasite can influence the IL-6 and IL-10 response, which is associated with increased parasitemia, reduced maternal weight gain and premature delivery.

Creating Perinatal Nursing Care Plans Using ChatGPT: A Pathway to Improve Nursing Care Plans and Reduce Documentation Burden.

Extensive time spent on documentation in electronic health records (EHRs) impedes patient care and contributes to nurse burnout. Artificial intelligence-based clinical decision support tools within the EHR, such as ChatGPT, can provide care plan recommendations to the perinatal nurse. The lack of explicit methodologies for effectively integrating ChatGPT led to our initiative to build and demonstrate our ChatGPT-4 prompt to support nurse care planning. We employed our process model, previously tested with 22 diverse medical-surgical patient scenarios, to generate a tailored prompt for ChatGPT-4 to produce care plan suggestions for an exemplar patient presenting with preterm labor and gestational diabetes. A comparative analysis was conducted by evaluating the output against a "nurse-generated care plan" developed by our team of nurses on content alignment, accuracy of standardized nursing terminology, and prioritization of care. ChatGPT-4 delivered suggestions for nursing diagnoses, interventions, and outcomes comparable to the "nurse-generated care plan." It accurately identified major care areas, avoided irrelevant or unnecessary recommendations, and identified top priority care. Of the 24 labels generated by ChatGPT-4, 16 correctly utilized standardized nursing terminology. This demonstration of the use of our ChatGPT-4 prompt illustrates the potential of leveraging a large language model to assist perinatal nurses in creating care plans. The next steps are improving the accuracy of ChatGPT-4-generated standardized nursing terminology and integrating our prompt into EHRs. This work supports our broader goal of enhancing patient outcomes while mitigating the burden of documentation that contributes to nurse burnout.

Immune Thrombocytopenic Purpura and Maternal and Neonatal Outcomes During Pregnancy: A Systematic Review and Meta-Analysis.

Immune thrombocytopenic purpura (ITP) affects 1-3 out of every 10000 pregnancies, posing significant risks to both mothers and newborns. The condition often requires careful management to prevent severe hemorrhagic events. PubMed, Embase, Scopus, and Web of Science searched for relevant literature until June 2024. A meta-analysis was performed to evaluate the effect of ITP on maternal and fetal outcomes. The results showed that antepartum hemorrhage occurred in 0.17 (95% CI = 0.12-0.25) of patients and postpartum hemorrhage occurred in 0.11 (95% CI = 0.07-0.16) of pregnant women with ITP. About 0.63 (95% CI = 0.50-0.74) of pregnant women needed treatment for ITP. The cesarean section (CS) rate was 0.48 (95% CI = 0.34-0.61), and the occurrence of preterm labor was 0.14 (95% CI = 0.07-0.24). A total of 0.32 of neonates had thrombocytopenia (95% CI = 0.18-0.52). The difference between the platelet count of those diagnosed with ITP before pregnancy and those diagnosed after pregnancy was significant (MD=-31.50, 95% CI=51.29-11.72, p<0.01). This meta-analysis highlights the significant impact of ITP on pregnancy, estimating risks of bleeding, CS, gestational diabetes, preterm labor, and neonatal thrombocytopenia. These findings underscore the need for vigilant monitoring and tailored management of pregnant women with ITP.

Association between Gestational Bisphenol A Exposure and Maternofoetal Outcomes: A Cohort Study in a Single Tertiary Hospital in Klang Valley

A growing body of literature has documented the adverse effects of bisphenol A (BPA) exposure on pregnancy and birth outcomes. Regardless, how gestational BPA exposure affects mother-newborn pairs in Malaysia is yet to be explored. Hence, this study aimed to investigate urinary BPA levels of pregnant women living in Klang Valley and their associations with adverse obstetric and birth outcomes. This cross-sectional study involved pregnant women in their third trimester attending antenatal clinic in Hospital Al Sultan Abdullah (HASA), UiTM Puncak Alam, who planned to have their delivery in HASA. Information on maternal age, parity, education, household income, gestational age, and obstetric complications, such as Gestational Diabetes Mellitus (GDM), preeclampsia, preterm labour, and foetal growth restriction (FGR) were collected. Maternal urine samples were also obtained and evaluated using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Additionally, the neonatal outcomes including mode of delivery, gestational age, birth weight and need for NICU admission were documented. Our LC-MS/MS analysis showed that BPA was present in all the urine samples, with levels varying from 4.42 to 30.86 ng/mL. The median level was 15.96 ng/mL. Urinary BPA level has no significant correlation with gestational hypertension (GHTN), preterm labour and low birth weight babies. Babies who need NICU admission were born to mothers who exhibited significantly different urinary BPA levels compared to those whose babies were not admitted (p=0.049). Finding from this study suggestive of further investigation on level of gestational urinary BPA with NICU admission, ideally with a larger sample size to validate these results.

Tocolysis and Neurodevelopment of Children Born Very Preterm

Neurodevelopmental outcomes of very preterm children exposed to tocolytics are not well described. To investigate whether tocolysis administered after spontaneous preterm labor is associated with neurodevelopmental outcomes at 5.5 years and to assess whether the type of tocolytic drug is associated with neurodevelopmental outcomes among infants exposed. This prospective, national, population-based cohort study used data from the French Etude Épidémiologique sur les Petits Âges Gestationnels-2 cohort. Children who were alive and participated in an assessment at 5.5 years and whose mothers experienced spontaneous preterm labor without an infectious context and delivered at 24 to 31 weeks were eligible for this study. Recruitment occurred from March to December 2011. Follow-up at age 5.5 years was conducted from September 2016 to December 2017. Data analysis was performed from July 2023 through April 2024. The primary analysis examined tocolytics (yes vs no), and the secondary analysis examined the type of tocolytic (atosiban vs calcium channel blockers [CCBs]). The composite outcome neurodevelopmental disabilities included cerebral palsy; visual, hearing, and cognitive deficiencies; developmental coordination disorders; or behavioral problems. A total of 1055 mothers (mean [SD] age, 29.2 [5.7] years) had preterm labor without fever and gave birth to 1320 children (704 male [weighted percentage, 53.3%; 95% CI, 50.6%-56.1%]; mean [SD] gestational age, 28.8 [2.0] weeks). Overall, 776 mothers (weighted percentage, 73.5%; 95% CI, 70.8%-76.2%) received tocolytics; 136 mothers (weighted percentage, 17.9%; 95% CI, 15.3%-20.8%) received only a CCB, and 295 mothers (weighted percentage, 37.6%; 95% CI, 34.2%-41.0%) received only atosiban. From modified Poisson regression with propensity score matching, the risk of overall neurodevelopmental disabilities (mild, moderate, or severe) at 5.5 years did not differ between preterm children exposed and not exposed to tocolytics (relative risk [RR], 1.11; 95% CI, 0.85-1.45; P = .44) or in preterm infants exposed to atosiban compared with those exposed to CCBs (RR, 0.94; 95% CI, 0.67-1.32; P = .71). In this study, tocolytics were not associated with neurodevelopmental disabilities among very preterm children surviving at 5.5 years.

Asymptomatic bacteriuria screening for developing countries using a modified water quality test kit.

Between 2% and 15% of pregnant women unknowingly experience asymptomatic bacteriuria (ASB), defined as ≥105 CFU per milliliter of urine in the absence of symptoms. ASB increases the risk of adverse pregnancy outcomes including pyelonephritis, preterm labor, and low-birth weight infants. While pregnant women in the United States are routinely screened for ASB, those in developing countries with limited resources and funding lack an accurate mechanism for ASB screening. Aquagenx water quality test kits detect Escherichia coli, the most common causative agent of ASB, and total coliform bacteria in drinking water via colorimetric and fluorescent indicators. We found that the Aquagenx system is compatible with human urine and then proceeded to develop an ASB screening protocol using disposable inoculating loops. Our protocol diagnosed artificial ASB- samples (104 CFU/mL E. coli) with a false positive (FP) rate of 33% (n = 18) and ASB+ (105 CFU/mL E. coli) with a false negative (FN) rate of 5.6% (n = 18). Clinical sample testing with our protocol revealed a FP rate of 0% in ASB- samples (n = 28) and a FN rate of 0% in ASB+ samples caused by coliforms (n = 13). Aquagenx did not detect ASB in nine clinical samples with non-coliform etiological agents due to the limitations of the technology. However, with very high accuracy for detection of E. coli and other causative agents that collectively account for 90.1% of ASB cases, these kits could be used as a diagnostic ASB screening tool in developing countries in which there is currently no alternative to urine culture.IMPORTANCEAsymptomatic bacteriuria (ASB) affects 2%-15% of pregnant women and can result in adverse maternal and fetal outcomes if left undetected and untreated. In the United States and other developed nations, pregnant women are regularly screened for ASB via urine culture. However, in low-resource countries where bacterial culture is not available, dipstick testing is used. Although accurate in cases of symptomatic bacteriuria, dipstick detection is ineffective for detecting ASB. Here, we made use of an existing water quality field test for ASB urine screening, which would be readily deployable in low-resource settings. We optimized a dilution protocol for sampling patient urine within the detection limits of the Aquagenx kit technology. Overall, we were able to detect ASB samples with Gram-negative pathogens that collectively account for 90% of all ASB cases. Utilization of this repurposed technology for proactive medical screening may help prevent adverse pregnancy and birth outcomes due to ASB.

Intrauterine infusion of autologous platelet rich plasma can be an efficient treatment for patients with unexplained recurrent implantation failure

The studies posits that there is not sufficient evidence to support the use of intrauterine platelet-rich plasma (PRP) infusion in patients with recurrent implantation failure (RIF). This study aims to investigate the effects of infusion of PRP on patients with unexplained-RIF in fresh and frozen embryo transfer (ET) cycles. A total of 80 participants were included in this study. The participants were randomly assigned to one of two groups with and without PRP infusion. Each of the PRP and control groups were also divided into fresh and frozen ET subgroups. ET outcomes were compared between groups. Clinical pregnancy rate was significantly higher in Frozen ET in PRP group than other subgroups (p < 0.0001). Miscarriage rate were significantly lower in PRP group than control group. Pregnancy complications and preterm labor were significantly higher in PRP group than control group (p < 0.0001). Live birth and healthy baby rate were significantly higher in PRP group than control group (p < 0.0001). The intrauterine infusion of 0.8-1 ml of PRP 48 h before blastocyst ET at fresh and frozen cycles can be an efficient treatment option for u-RIF patients. Also, results indicated that the clinical pregnancy rate was equal to the live birth rate at fresh ET cycles, whereas the live birth rate was lower than the clinical pregnancy rate at frozen ET cycles. Therefore, considering the superiority of fresh cycles over freeze cycles, the infusion of PRP into the uterus of patients with RIF is recommended to be done at fresh ET cycles.Trial registration: NCT, NCT03996837.

Severity of pulmonary hypertension and pregnancy outcomes: newer insights from the M-PAC registry

Abstract Background Pregnancy outcomes in women with pulmonary hypertension remain suboptimal. Pregnant women with pulmonary hypertension (PH) are placed in the modified WHO category IV, regardless of the severity or etiology of PH. Earlier studies have indicated that pregnancy outcomes may differ based on the etiology, with more favourable outcomes observed with PH related to left to right shunts. However, it is possible that the pregnancy outcomes may vary based on the severity of PH also. Purpose To analyse pregnancy outcomes in women with PH and investigate differences based on disease severity. Methods M-PAC Registry, is a single center prospective study of pregnancies in women with heart diseases, conducted between July 2016 and December 2019 in a low-and middle-income country from South Asia, whose methodology and outcomes have been published(1). The current study analysed pregnancies with PH enrolled in the M-PAC registry. The tricuspid regurgitation velocity obtained during transthoracic echocardiography, was used to estimate right ventricular systolic pressure (RVSP). Based on the estimated RVSP, PH was classified into three groups; mild (36-45 mm of Hg), moderate (46-64 mm of Hg) and severe (≥ 65 mm of Hg). The differences in the maternal and foetal outcomes among the groups were analysed. Results Of the 1029 pregnancies complicated by heart disease enrolled in the M-PAC registry, 352(34.2%)had PH. Among these 352 pregnancies, 186(52.8%) had mild, 73 (20.7%) had moderate and 93 (26.5%) had severe PH. Adverse maternal cardiac events occurred in 77 pregnancies (21.8%), with heart failure in 53(15.1%) and mortality in 10(2.8%). The composite adverse foetal event rate was 38.6%, foetal loss at 9.7%, low birth weight at 28.9%, and preterm labour at 7.1%. The mean (±standard deviation) RVSP was higher in pregnancies with adverse maternal outcome (58.81±16.9 vs 51.16±15.9; P &amp;lt; 0.001) or adverse foetal outcome (58.10±17.3 vs 49.52±14.9; P &amp;lt; 0.001)compared to those without. When comparing the three groups, pregnancies with mild PH exhibited significantly lower rates of adverse maternal and fetal events compared to those with severe and moderate PH (Fig-1 and Table-1). Mild PH was associated with outcomes similar to those without PH in the M-PAC registry. Conclusion The severity of PH significantly correlated with the adverse pregnancy outcomes. Women with mild PH tend to experience pregnancy outcomes comparable to those without PH, suggesting that pregnancy should not be deemed contraindicated in this subgroup. Therefore, re-evaluation of the placement of PH within the modified World Health Organization (mWHO) classification is warranted, considering the severity of PH.Figure 1:Pregnancy Outcomes &amp; PH SeverityTable-1 PH Severity &amp; Pregnacny Outcomes

The impact of intimate partner violence on adverse birth outcomes in 20 sub-Saharan African countries: propensity score matching analysis

BackgroundIntimate partner violence (IPV) is a significant public health problem, with serious consequences on women's physical, mental, sexual, and reproductive health, as well as birth outcomes. Women who encounter IPV are more likely to experience adverse birth outcomes such as low birth weight, premature delivery, and stillbirth. Although numerous studies are exploring the association between IPV and adverse birth outcomes, they merely used classical models and could not control for potential confounders. The purpose of this study was to ascertain whether there was a causation between IPV and adverse birth outcomes in sub-Saharan Africa (SSA) using a quasi-experimental statistical technique [i.e., propensity score matching (PSM) analysis].MethodThis study used the most recent (2015–22) Demographic and Health Survey (DHS) data from 20 SSA countries. A total weighted sample of 13,727 women was included in this study. IPV (i.e., sexual, physical, emotional, and at least one form of IPV) was the exposure/treatment variable and adverse birth outcomes (preterm delivery, low birth weight, stillbirth, and macrosomia) were the outcome variables of this study. PSM was employed to estimate the impact of IPV on adverse birth outcomes.ResultsThe average treatment effects (ATE) of sexual, physical, emotional, and at least one form of IPV were 0.031, 0.046, 0.084, and 0.025, respectively. Sexual, physical, emotional, and at least one form of IPV increased adverse birth outcomes by 3.1%, 4.6%, 8.4%, and 2.5%, respectively. Findings from the average treatment effect on treated (ATT) showed that women who experienced sexual, physical, emotional, and at least one form of IPV had an increased risk of adverse birth outcomes by 3.6%, 3.7%, 3.3%, and 3.0%, respectively, among treated groups.ConclusionThis study demonstrates a causal relationship between IPV and adverse birth outcomes in SSA countries, indicating a need for programs and effective interventions to mitigate the impact of IPV during pregnancy to reduce related adverse pregnancy outcomes. Furthermore, we suggest further research that investigates the causal effect of IPV on adverse birth outcomes by incorporating additional proximal variables not observed in this study.

Outcome of pregnancy in women with unrepaired atrial septal defect - study of a single tertiary centre

Abstract Background Patients with unrepaired atrial septal defect (ASD) are prone to develop arrhythmia, right heart failure and to suffer paradoxical embolism. The risk might be even bigger during pregnancy due to the hemodynamic changes combined with the hypercoagulable state. Purpose To evaluate maternal, foetal, and neonatal outcome of pregnancy in women with unrepaired ASD. Methods A retrospective study of 43 pregnancies in 24 women with unrepaired ASD was performed in our tertiary centre from 2004. Previous maternal cardiovascular events and events during pregnancy (maternal, neonatal, and obstetric) were documented. Results 24 women with unrepaired ASD (median age: 27.5 ± 6.2) had 43 pregnancies resulting in one termination, 4 miscarriages and 38 live births. 55% were primigravida and 2 twin pregnancies were documented. At baseline 2 women (10.5%) were in NYHA functional class II and signs of right ventricle (RV) volume overload were detected on echocardiography in 18 cases (47%). 2 women had a history of supraventricular tachycardia. Median gestation at delivery was 39 ± 2.6 weeks. No thromboembolic events, pulmonary hypertension, or desaturation occurred during pregnancy. However maternal cardiovascular complications all affected women with RV volume overload: 2 cases (5.2%) of supraventricular tachycardia, 2 (5.2%) cases with NYHA functional class deterioration and 1 case (2.6%) of syncope were documented. Only one obstetric event; preeclampsia occured. Neonatal complications were as follows: premature delivery in 3 cases (7.9%) and recurrence of congenital heart disease (CHD) in 4 pregnancies (10.5%). After the pregnancy device or surgical closure of the ASD was indicated for 11 women (45.8%). Since then, five already underwent device closure, one had surgical repair, while five women are still waiting for intervention. Conclusions Our results align with the mWHO classification. Pregnancy with an unrepaired ASD is well tolerated and has a low risk of neonatal and maternal cardiovascular events. However, women with right ventricle volume overload are prone to develop arrhythmia or right heart failure during pregnancy. Therefore, cardiology follow-up during pregnancy should be decided on an individual basis. In our cohort no thromboembolic events were documented during pregnancy, however the prevalence of congenital heart disease in the foetus was higher compared to the literature.

Exploring factors associated with domestic violence among pregnant women in Pakistan and its implications for maternal and perinatal health

ABSTRACT Domestic violence during pregnancy is a critical health issue due to its significant implications for both maternal and fetal well-being. Women in South Asian countries are particularly at a higher risk of experiencing domestic violence. The objective of this study was to identify factors associated with domestic violence among pregnant women attending tertiary care antenatal services in Pakistan. The secondary aim was to evaluate the impact of domestic violence on maternal and perinatal outcomes. The study participants were 681 pregnant women registered for antenatal care and delivery at a tertiary care hospital in Islamabad, Pakistan. Data were collected through in-person surveys and medical chart reviews. Associations between domestic violence and study variables were examined by logistic regression analysis. Among the study participants, 31.4%experienced some form of domestic violence during pregnancy, with psychological abuse (16.4%) being the most prevalent followed by sexual abuse (9.5%) and physical violence (1.8%). Women whose husbands were unemployed were three times more likely to experience domestic violence (aOR; 3.3, 95%CI: 1.6, 7.0). Similarly, husband’s substance abuse was significantly associated with domestic violence during pregnancy (aOR: 120.8, 95%CI: 57.9, 252.2). Domestic violence was a significant predictor of adverse maternal outcomes, including anemia, preterm labor, and recurrent abdominal pain. Similarly, domestic violence was a significant predictor of NICU admission (aOR: 20.6, 95%CI: 12.6, 33.8) and low birthweight (aOR: 24.4, 95%CI: 10.2, 58.4). The study findings emphasize the urgent need for comprehensive interventions targeting domestic violence among women and preventing its cascading effects on pregnancies.

Diagnostic value of prenatal ultrasound screening and analysis of pregnancy outcomes in velamentous umbilical cord insertion

Objective: To explore diagnostic value of prenatal ultrasound screening in velamentous umbilical cord insertion (VCI) and its influence on perinatal outcomes, and to provide theoretical basis for clinical practice. Methods: Fifty-eight pregnant women diagnosed with VCI before or after delivery admitted to the First Affiliated Hospital of Xi'an Jiaotong University were selected from January 2012 to December 2022. The clinical features and perinatal outcomes of 45 women finally with VCI after delivery (VCI group) were retrospectively analyzed, and 225 women with normal umbilical cord attachment were selected as the control group during the same period. Results: (1) Among 58 women, 54 (93.1%, 54/58) were diagnosed with VCI by prenatal ultrasound screening, 4 patients (6.9%, 4/58) were missed; and 13 (22.4%, 13/58) were misdiagnosed. Finally, a total of 45 women were confirmed by postpartum placental examination, and 11 (24.4%,11/45) were combined with vasa previa. (2) There were no differences in age, number of pregnancies, and number of induced abortions between the two groups (all P>0.05). Compared with the control group, the rate of assisted reproductive technology [13.3% (6/45) vs 0.4% (1/225); P<0.01], and twin pregnancy rate [8.9% (4/45) vs 0.4% (1/225); P<0.01] in the VCI group were significant higher. (3) Compared with the control group, the rate of placenta previa, succenturiate placenta, vasa previa, postpartum hemorrhage, prenatal hemorrhage and postpartum intrauterine remainder in the VCI group were significant higher (all P<0.05); there was no significant difference in the incidence of placental abruption, premature rupture of membranes, fetal distress and single umbilical artery between the two groups (all P>0.05). The incidence of fetal structural abnormalities in the VCI group (4.4%, 2/45) was higher than that in the control group (1.3%, 3/225), but there was no significant difference between the two groups (P=0.195). (4) The cesarean section rate [75.0% (33/44) vs 45.1% (101/224); P<0.01], preterm birth rate [29.5% (13/44) vs 5.4% (12/224); P<0.01], rate of small for gestational age [20.5% (9/44) vs 5.4% (12/224); P<0.01] in the VCI group were significant higher. However, neonatal birth weight [(2 928±552) vs (3 353±498) g; P<0.01], and 1-minute Apgar score (median: 10 vs 10; P<0.01) in the VCI group were lower than those in the control group. Conclusions: Prenatal ultrasound screening is an important method to diagnose VCI. VCI is more prone to adverse pregnancy outcomes, such as postpartum hemorrhage, premature delivery, small for gestational age, et al. Its risk factors include twin pregnancy, assisted reproductive technology, placenta previa, and para-placenta.

Embryotomy for head last retention: A case report from Thiès, Senegal

Introduction: Hydrocephalus is a pathology of heterogeneous nature and complex pathogenesis. It corresponds to an active distension of the ventricular system. Faced with hydrocephalus with retained head in a dead child, embryotomy by craniotomy is indicated. Case Report: We report a case of intrapartum fetal death with head-last retention due to hydrocephalus treated with craniotomy performed at the regional hospital of Thiès (CHRT). This was a 21-year-old primigravida patient seen for premature delivery in a pregnancy of 33 weeks 5 days. The ultrasound concluded that the pregnancy had stopped at 33 weeks 5 days with major hydrocephalus. A craniotomy followed by gradual evacuation of the cerebrospinal fluid allowed easy delivery of a fresh stillborn weighing 1950 grams. The afterbirth was simple. Conclusion: Embryotomy by craniotomy constitutes a good option to complete delivery by natural means in the face of head retention due to hydrocephalus with intrapartum death. It is therefore necessary to master this simple and less morbid technique than a cesarean section in such a situation.

Impact of gestational age on the management of acute appendicitis during pregnancy: A nationwide observational study.

To compare conservative management and appendectomy for acute appendicitis during pregnancy by trimester. This retrospective cohort study used data from a national inpatient database from July 2010 to March 2022. Pregnant women diagnosed with acute appendicitis were included. Multivariable analysis using generalized estimating equations was performed to compare outcomes between conservative management and appendectomy across trimesters. The main outcomes were preterm labor, preterm delivery, or abortion; antepartum hemorrhage; duration of hospitalization; and duration of antibiotic use. A total of 3158 individuals from 632 acute-care hospitals were eligible. The proportion of conservative management versus appendectomy by trimester were 507 (49.1%) versus 525 (50.9%) in the first, 690 (44.6%) versus 856 (55.4%) in the second, and 337 (58.1%) versus 243 (41.9%) in the third. In the second trimester, appendectomy was associated with a higher rate of preterm delivery, preterm labor, or abortion (odds ratio [OR], 2.91 [95% confidence interval (CI), 1.62-5.25]). Antepartum hemorrhage occurred more frequently for appendectomy in the first (OR, 2.12 [95% CI, 1.31-3.43]) and third (OR, 2.43 [95% CI, 1.79-3.31]) trimesters. Appendectomy was associated with a longer duration of hospitalization in the second (2.15 days; 95% CI, 1.14-3.17 days) and third (3.97 days; 95% CI, 2.22-5.71 days) trimesters. Antibiotic use duration was shorter for appendectomy in the first (-1.20 days [95% CI -1.51 to -0.90 days]) and second (-0.61 days [95% CI -0.90 to -0.32 days]) trimesters. Clinical outcomes of acute appendicitis during pregnancy vary by trimester. Considering the appendectomy risks, conservative management may be viable depending on the clinical context and trimester.

Risk factors for neonatal admission from the beginning of pregnancy in Northeast Spain.

Maternal health and gestational control are crucial to improving the newborn's prognosis. This study analyses demographic and obstetric factors at the beginning of pregnancy related to neonatal health, assessing their impact on the risk of hospital admission and prematurity. Observational retrospective study conducted in Northeast Spain with data of 9560 newborns between February 2017 and February 2022. The following have been evaluated as risk factors for hospital admission: nulliparity, multiple gestation, fertilisation techniques, foreign maternal origin, maternal age, smoking and residential location, dividing the sample according to gestational age. Hypothesis testing and logistic regression were performed. Nulliparity, fertilisation techniques and multiple gestation represent a risk factor for neonatal admission (OR 22.48, 4.04 and 3.34, respectively), especially in premature newborns <32 weeks of GA (OR: 30.71, 10.71 and 22.76, respectively). Foreign maternal origin also adds risk of admission, both in term newborns (OR 1.26; CI: 1.10-1.43) and in premature babies <32 weeks of GA (OR 1.61; CI: 1.09-2.38). Tobacco does not present a significant risk of neonatal admission. The multivariate analysis model confirms the influence of the following factors in all the studied groups: nulliparity, multiple gestation and foreign maternal origin. Nulliparity and multiple pregnancies are both main risk factors for neonatal admission and premature delivery. The use of fertilisation techniques and the foreign origin of the mother significantly associate increased risk of admission and neonatal prematurity. These findings underscore the need for a comprehensive approach to prenatal care to improve neonatal prognosis and promote long-term health in risk populations.

Outcomes of COVID-19 in Pregnant Women: A Retrospective Analysis of 300 Cases in Jordan

Background: The impact of COVID-19 on pregnancy remains a critical area of research, with growing evidence suggesting that maternal infection, particularly in the third trimester, may lead to significant complications Aims: The primary aim was to investigate the maternal and neonatal outcome of pregnant Jordanian women with COVID-19. The secondary aim included exploring demographics, obstetrics characteristics, and comorbidities among these women. Methods: A retrospective comprehensive review of the records of 300 cases of pregnant women with COVID-19, who were treated between November 2020 and April 2021 at Queen Alia Military Hospital (a main referral center for patients with COVID-19) in Jordan. All cases were confirmed by the rapid antigen test (RAT) + long polymerase chain reaction (PCR) test used to detect SARS-CoV-2 by amplifying viral RNA from patient samples. Women infected with COVID-19 were categorized into four groups according to the RCOG guidelines for COVID-19 infection in pregnancy: asymptomatic, mild, moderate, and severe cases. All cases were managed following the Royal College of Obstetricians and Gynecologists protocol for COVID-19 in pregnancy. Data extracted from patient’s records included demographic information, COVID-19 clinical manifestations, obstetric history, diagnostic findings, treatment plans, comorbidities, gestational age at diagnosis, treatment protocols, and maternal and neonatal outcomes. Results: The mean age was 29.7 years; 98.3% were nonsmokers; 8% had previous miscarriages, and 67.3% had the infection in the third trimester. Iron deficiency anemia affected 30.3%, while 18.3% had comorbidities, mainly hypothyroidism. Most women were asymptomatic 61.7%, but 33% had respiratory symptoms, 4.7% needed intensive care unit (ICU) admission, and 2.7% resulted in maternal deaths. First-trimester and second-trimester miscarriages were recorded in 2.67% and 3.67% of cases, respectively, while preterm labor occurred in 3.0% of pregnancies. Additionally, age and hospitalization duration had a positive correlation with the neonatal outcomes (r = 0.349, p &lt; 0.01), (r = 0.376, p &lt; 0.01), respectively. Furthermore, COVID-19 presentation and treatment options demonstrated a strong positive correlation (p-value &lt;0.01). On the other hand, maternal death had a strong negative correlation with poor neonatal outcomes (r = −0.776, p &lt; 0.01). Conclusion: The study showed that COVID-19 in pregnant women, particularly in the third trimester, is associated with significant neonatal complications, with age, hospitalization duration, and COVID-19 severity strongly impacting outcomes.

Lupus activity and pregnancy outcomes in systemic lupus erythematosus patients undergoing assisted reproductive therapy: A systematic review and meta-analysis.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease primarily impacting women of childbearing age. While pregnancy and hormonal stress can trigger SLE flare-ups, the effects of assisted reproductive therapies (ARTs) on SLE patients are not well defined. We conducted a search of PubMed/Medline, Embase, and CENTRAL until March 20, 2024, to find observational studies assessing the prevalence of SLE flares and pregnancy outcomes following ARTs. Our analysis included random-effects meta-analysis and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach for evaluating evidence quality. Five studies involving 237 SLE women who underwent ARTs were eligible. The meta-analysis indicated a prevalence of SLE flares at 17% (95% CI: 10-25%) with moderate-quality evidence. The pooled prevalence of arthritis flares was 7% (95% CI: 0-25%) with low-quality evidence. Successful pregnancy rates were 58% (95% CI: 43-72%), and live birth rates were 96% (95% CI: 83-100%), both with low-quality evidence. Moderate-quality evidence showed pregnancy complications, including preterm premature rupture of membranes (PPROM) at 8% (95% CI: 3-16%), miscarriages at 2% (95% CI: 0-9%), intrauterine fetal demise (IUFD) at 4% (95% CI: 0-11%), and preeclampsia at 7% (95% CI: 1-17%). Low-quality evidence showed preterm labor at 10% (95% CI: 0-32%) and ovarian hyperstimulation syndrome (OHSS) at 2% (95% CI: 0-11%). SLE flares, as well as pregnancy complications such as IUFD, miscarriage, PPROM, and preeclampsia in ART recipients, are equivalent to those in spontaneous conception. This indicates that ART is relatively safe for SLE patients with meticulous pregnancy planning. Key Points •Systemic lupus erythematosus (SLE) is a chronic autoimmune disease primarily impacting women of childbearing age. • Pregnancy in women with SLE poses elevated maternal and fetal risks compared to healthy women. • SLE flares and pregnancy complications while receiving ART are equivalent to those in spontaneous conception and ART is relatively safe for SLE patients.

Severe Deep Fascial Spaces Infections with Pregnancy: A Retrospective Study.

Background: Odontogenic infections are common and self-limiting in most cases, but, they can lead to severe consequences and considerable morbidity and can even be fetal in spite of modern medical therapy. Patients and Methods: Retrospective study included data of pregnant patients with deep fascial space infections, done in Oral & Maxillofacial Surgery Department, Faculty of Dentistry. Alexandria University, and Oral & Maxillofacial Surgery Department, King Fahd Specialist Hospital, Burayda, Qassim, Saudi Arabia, from June2017 to Dec2022. Data were analyzed to study incidence, etiology, pattern, treatment modalities, outcomes, complications, and effects on pregnancy. Results: Thirty-eight pregnant patients, with a mean age of 30.8 ± 6.21 years, were included. The mean age of pregnancy was 24.5 ± 4.3 weeks. Diabetes mellitus was identified in seven cases (18.42%) and combined with hypertension in one case (2.63%) and with valvular heart disease in another one. The commonest affected single space was the submandibular space that occurred in six cases (15.8%). Canine space was the second single commonly involved one which occurred in five patients (13.2%). Complications occurred in 11 patients. Unesthetic scar occurred in three patients (7.9%). Trismus was observed in two patients (5.3%). Recurrent abscess was found in one case. Complications affecting the developing fetus and considered the most serious occurred in four patients: two cases of preterm labor and two cases of abortion. Conclusion: These infections may lead to serious outcomes and may have irreversible effects on the pregnancy and the developing fetus. Urgent intervention with multidisciplinary team to provide adequate care.

Ultrasonographic placental edematous changes as predictive markers of unplanned preterm birth in post-Fontan pregnancies: A single-center observational study.

Fontan surgery is a palliative procedure commonly performed for functional single-ventricle heart diseases. Fontan circulation is characterized by elevated central venous pressure and low cardiac output. It causes placental hypoxia, which could lead to poor obstetric outcomes. During post-Fontan pregnancies, ultrasonography may detect abnormal appearance of the placenta. We have focused on higher incidences of unexpected onset of labor when this ultrasonographic finding is present. In this study, we aimed to investigate whether this finding could be an indicator of premature delivery before pre-scheduled dates in post-Fontan pregnancies. During post-Fontan pregnancies, the placenta exhibits a mosaic pattern with areas of low and high echogenicity and unusually thick on ultrasonography. We refer to these changes as "ultrasonographic placental edematous changes." We retrospectively analyzed clinical charts and ultrasonograms for post-Fontan pregnancies between 2015 and 2022. Fifteen patients were included in this study. Ultrasonographic placental edematous changes in the placenta during pregnancy were detected in eight cases (53%). Six (75%) of these patients experienced unexpected premature labor. Two patients underwent vaginal delivery because of sudden onset of labor. Four patients underwent emergency cesarean sections. Two patients underwent planned preterm cesarean sections. In the seven pregnancies without placental edematous changes, all deliveries occurred on the pre-scheduled dates determined based on the maternal heart condition. Pregnancies with ultrasonographic placental edematous changes have a higher risk of unexpected preterm delivery than those without these changes. Ultrasonographic placental edematous changes may serve as predictive markers for unplanned preterm births in post-Fontan pregnancies.

Effects of supportive hemodialysis on the management of a pregnant woman with advanced chronic kidney disease: a case report and literature review

BackgroundPregnancy in women with chronic kidney disease (CKD) is associated with an increased risk of adverse maternal and fetal outcomes, including worsening renal function, hypertension, proteinuria, preeclampsia, preterm delivery, stillbirth, and intrauterine growth restriction. Some pregnant women with CKD may require dialysis after conception. Clinical guidelines provide recommendations for optimal hemodialysis prescription in pregnant women undergoing maintenance hemodialysis for end-stage kidney disease. However, the timing of initiation and optimal doses of hemodialysis for pregnant women with non-dialysis advanced CKD remain uncertain.Case presentationWe describe the case of a 29-year-old woman with a history of CKD for at least 2 years. She was referred to our department with a serum creatinine level of 2.48 mg/dL and an estimated glomerular filtration rate of 20 mL/min/1.73 m2. Because she was found to be pregnant at the initial visit, she was referred to the Department of Obstetrics. At 23 weeks’ gestation, she was admitted due to threatened premature delivery and urinary tract infection, which were managed with ritodrine hydrochloride and antibiotics. Owing to maternal weight loss and asymmetrical fetal growth restriction, daily protein intake was increased from 40 g/day to 60–80 g/day. Additionally, supportive hemodialysis (three times per week) was initiated at 26 weeks’ gestation, and the pre-dialysis blood urea nitrogen (BUN) level was consistently maintained < 40 mg/dL. Consequently, the patient’s weight increased, and fetal growth recovered. Because her blood pressure increased particularly during and after dialysis sessions, dialysis was discontinued at 32 weeks’ gestation. Urinary protein increased to a nephrotic level, and blood pressure was poorly controlled by medication, suggesting the onset of preeclampsia. Thus, a cesarean section was performed at 33 weeks’ gestation, and she delivered a male baby weighing 1449 g. Following childbirth, the patient did not require hemodialysis.ConclusionsSupportive hemodialysis during pregnancy in women with advanced CKD can increase maternal protein intake without elevating BUN levels, leading to improved fetal growth.
