Aeromedical retrieval for suspected preterm labour or rupture of membranes in the Northern Territory, Australia: may some cases be safely not retrieved?

BackgroundSuspected preterm labour (PTL) and prelabour rupture of membranes (PPROM) are common indications for aeromedical retrieval in the Top End, Northern Territory, Australia, where many women reside remotely and preterm birth (< 37 completed weeks of gestation) is common. The primary objective of this study was to determine rate of delivery during the index admission following aeromedical transfers from remote clinics to Royal Darwin Hospital for suspected PTL/PPROM.MethodsA retrospective cohort study of aeromedical transfers for suspected PTL/PPROM from 1 January 2020 to 31 July 2022 was undertaken. Transfers were identified through CareFlight, the regional air ambulance service, and complemented with data from hospital records. Clinical and sociodemographic characteristics were compared by delivery status during the index (post-retrieval) admission using parametric and non-parametric tests and multivariable linear regression analysis.Results238 women with singleton pregnancies were retrieved for suspected PPROM (n = 77, 32.4%) or PTL (n = 161, 67.6%), together accounting for 49.2% of all obstetric transfers (n = 483). Of 77 patients transferred for suspected PPROM, 47 (61.0%) had ruptured membranes confirmed on arrival, and 45 (95.7%) of them delivered during the index admission. None of the 30 women transferred for suspected PPROM with intact membranes on arrival delivered during the index admission. Of 161 patients transferred for suspected PTL, 13 (8.1%) had ruptured membranes confirmed on arrival, and 12 (92.3%) of them delivered during the index admission. Amongst women transferred for suspected PTL with intact membranes confirmed on arrival, 14.9% (22/149) delivered during the index admission. Prior to arrival, 120 women (50.4%) had a documented speculum examination, and 15 (6.3%) and 9 (3.8%) had cervicovaginal swab tests to assess their risks of a PPROM and PTL, respectively. Half of women who did not deliver during the index admission had received antenatal corticosteroids (n = 76).ConclusionsMany aeromedical retrievals for suspected PTL/PPROM did not result in delivery during the index admission. Women retrieved for suspected PPROM with intact membranes on arrival were less likely to deliver. Upskilling remote clinic staff and better point-of-care testing may reduce retrievals and unnecessary interventions. Prospective cohort studies designed to enable accurate prediction of which cases can be safely not retrieved are required.Trial registrationNot applicable.

Management Practices for Hemodynamic Impairment in Neonates Born Prematurely: A Quality Improvement Project.

Background: No consensus exists on the management of hemodynamic impairment in very premature neonates. At level 3 NICU, the protocol involves an initial infusion of crystalloids, followed by a cardiac ultrasound if the infusion fails to restore appropriate hemodynamics. Based on the ultrasound findings, a decision is then made regarding a second infusion or the prescription of vasopressor amines. The aim of the present study was to assess the effect of and compliance with this management practice in neonates born prematurely between 26 and 31 completed weeks of gestation following a plan-do-study-act design. Methods: Data were collected retrospectively from patient records for all neonates who were managed for hemodynamic impairment within the first 24 h of life. Results: Of 604 neonates born during the study period, 68 were included in this study, but only eight cases followed the protocol. Reasons for non-compliance were the absence of cardiac ultrasound and variations in the duration and dosage of fluid administration. There was a significant relationship between blood pressure and positive inspiratory pressure levels at the time of management and compliance with the protocol. Conclusions: A revision of the protocol will emphasize the importance of echocardiography assessment, as all neonates responded to the ultrasound-guided therapy. As a quality improvement measure, attending neonatologists will be trained to thoroughly adhere to the protocol before the next evaluation.

Maternal and fetal outcome of postdated pregnancy; A cross sectional study

Background: Postdated pregnancy refers to a pregnancy that extends beyond the expected date of delivery, which is 280 days. When a pregnancy surpasses 42 weeks (more than 294 days), it is termed as post-term pregnancy. Postdated pregnancy is one of the most common obstetric problems associated with increased maternal and foetal morbidity, and mortality. Gestational age is among the most important determinants of perinatal outcomes, but studies have focused more on preterm births (&lt;37 completed gestational weeks) and less on the understanding and prevention of post term births. Objectives: To assess the maternal and fetal outcome of postdated pregnancy. Material and Methods: Present observational descriptive cross sectional study was conducted for the period of 1 year from 1st April 2023 to 31st March 2024. Total 150 postdated pregnant women included in present study as per predefined after satisfying the inclusion and exclusion criteria. Results: During study period out of total deliveries 110 were postdated deliveries. Out of them 46.36% and 28.18% were of 21-25 years and 26-30 years of age respectively. The mean age of all participants was 25.51 ± 4.58 years. A statistically significant association was found between the gestational age of postdated women and their mode of delivery. Out of 110 postdated women, 68.18% and 31.81% had vaginal and caesarean deliveries, respectively. Conclusion: Adverse maternal and fetal outcomes of post-dated pregnancy should be anticipated and counseling of women at risk of post-term pregnancy and timely management for its prevention is recommended

Invasive ventilation at the boundary of viability: A respiratory pathophysiology study of infants born between 22 and 24 weeks of gestation

BackgroundInvasive ventilation of infants born before 24 weeks of gestation is critical for survival and long-term respiratory outcomes, but currently there is a lack of evidence to guide respiratory management. We aimed to compare respiratory mechanics and gas exchange in ventilated extremely preterm infants born before and after 24 weeks of gestation. MethodsSecondary analysis of two prospective observational cohort studies, comparing respiratory mechanics and indices of gas exchange in ventilated infants born at 22–24 weeks of gestation (N=14) compared to infants born at 25–27 weeks (N=37). The ventilation/perfusion ratio (VA/Q), intrapulmonary shunt, alveolar dead space (VDalv) and adjusted alveolar surface area (SA) were measured in infants born at the Neonatal Unit of King’s College Hospital NHS Foundation Trust, London, UK. ResultsCompared to infants of 25–27 weeks, infants of 22–24 weeks had higher median (IQR) intrapulmonary shunt [18 (4 - 29) % vs 8 (2 – 12) %, p=0.044] and higher VDalv [0.9 (0.6 – 1.4) vs 0.6 (0.5 – 0.7) ml/kg, p=0.036], but did not differ in VA/Q. Compared to infants of 25–27 weeks, the infants of 22–24 weeks had a lower adjusted SA [509 (322- 687) vs 706 (564 - 800) cm2, p=0.044]. The infants in the two groups did not differ in any of the indices of respiratory mechanics. ConclusionVentilated infants born before 24 completed weeks of gestation exhibit abnormal gas exchange, with higher alveolar dead space and intrapulmonary shunt and a decreased alveolar surface area compared to extreme preterms born after 24 weeks of gestation.

Lamivudine dosing for preterm infants exposed to HIV: a population pharmacokinetic modelling and simulation study.

To develop a pragmatic twice daily lamivudine dosing strategy for preterm infants from 24 to 37 completed weeks of gestation. Data were combined from eight pharmacokinetic studies in neonates and infants receiving lamivudine oral solution. A population pharmacokinetic model was developed using non-linear mixed effects regression. Different lamivudine dosing strategies, stratified by gestational age at birth (GA) bands, were simulated in a virtual population of preterm infants, aimed at maintaining lamivudine drug exposures (AUC0-12) within a reference target range of 2.95 to 13.25 µg·h/mL, prior to switching to WHO-weight band doses when ≥4 weeks of age and weighing ≥3 kg. A total of 154 infants (59% female) contributed 858 lamivudine plasma concentrations. Median (range) GA at birth was 38 (27-41) weeks. At the time of first pharmacokinetic sampling infants were older with median postnatal age (PNA) of 6.3 (0.52-26.6) weeks. Lamivudine concentrations were described by a one-compartment model, with CL/F and V/F allometrically scaled to weight. Maturation of CL/F was described using an Emax model based on PNA. CL/F was also adjusted on GA to allow extrapolation for extreme prematurity. Simulations predicted an optimal lamivudine dosing for infants GA ≥24 to <30 weeks of 2 mg/kg twice daily from birth until weighing 3 kg; and for GA ≥30 to <37 weeks, 2 mg/kg twice daily for the first 4 weeks of life, followed by 4 mg/kg twice daily until weighing 3 kg. Model-based predictions support twice daily pragmatic GA band dosing of lamivudine for preterm infants, but clinical validation is warranted.

A Cross-sectional Study on the Awareness of Miscarriage among Students of the University of Cyberjaya

Miscarriage is generally defined as the loss of an intrauterine pregnancy before 24 completed weeks of gestation. The World Health Organization (WHO) defines miscarriage as ‘the expulsion from its mother of an embryo or fetus weighing 500 g or less, corresponding to a gestational age of up to 20 completed weeks of gestation with no signs of life’. This study serves as an initial investigation on the level of awareness of miscarriage among students of the University of Cyberjaya. It is a cross-sectional study which involves the students of University Of Cyberjaya, a set of questionnaires were distributed among themselves to determine the prevalence of the condition or knowledge in question. Overall, out of 449 respondents 73,7%; n:331 of the respondents are within the age of 20- 29 years old. The results of this study shows that four of five categories, which are the gender (female, 71%, p=0.004), age group (20-29 years old, 94.9%, p=0.002), ethnicity (Indian, 40.2%, p=0.013) and courses (MBBS, 52.1%, p=0.701) show remarkable associations with students' knowledge levels regarding miscarriage. It was also found that the respondents agreed on idea of substance abuse (57.0%, mean = 4.314) is the most common risk factor for miscarriage and the best preventative measure to overcome this problem is by controlling sugar levels, blood pressure, cholesterol, tobacco, and alcohol consumption (56.1%, p&lt;0.001). Our research also proves that there is a significant relationship among knowledge levels, awareness of risk factors, and the adoption of preventive measures related to miscarriage among students at the University of Cyberjaya. Higher knowledge levels are associated with increased awareness of risk factors (p&lt;0.001), and both knowledge and awareness are positively correlated with the adoption of preventive measures (p&lt;0.001 respectively).

Medical management of first trimester missed miscarriages - A cross-sectional study.

Miscarriage, a common complication of early pregnancy before 12 completed weeks of gestation, is typically managed medically. We aimed to estimate the success and complication rate of medical management in women with first-trimester missed miscarriages. Our objective was to calculate the rate of complete uterine evacuation within three weeks of treatment, rate of infection, significant blood loss, re-admission, or surgical evacuation. It was a retrospective cross-sectional study that included women diagnosed with miscarriage at less than 13 weeks' gestation in Latifa Hospital's Gynecology Department from January 2019 to December 2019 in Dubai. These patients were given vaginal misoprostol, 400-800 mcg every 6-8 hours until expulsion of pregnancy. There were 294 women included in the study. The success rate was 60.5% (178/294). Twenty women developed significant blood loss (6.8%), four women developed infection (1.4%), 76 required readmission (25.9%), 12 women received blood transfusion (4.1%), and 74 women required a surgical evacuation (25.2%). Nulliparity, unscarred uterus, and the presence of abdominal pain with vaginal bleeding before treatment were significantly associated with the successful medical treatment (p<0.05). The success rate of the medical regimen studied lies on the lower end of what is quoted in the literature. The difference in the success rate could be attributed to the different definitions of success in other studies. Nulliparity, unscarred uterus and presence of abdominal pain with vaginal bleeding were associated with higher success.

Stillbirth risk by fetal size among 126.5 million births in 15 countries from 2000 to 2020: A fetuses-at-risk approach.

To compare stillbirth rates and risks for small for gestational age (SGA), large for gestational age (LGA) and appropriate for gestational age (AGA) pregnancies at 24-44 completed weeks of gestation using a birth-based and fetuses-at-risk approachs. Population-based, multi-country study. National data systems in 15 high- and middle-income countries. Live births and stillbirths. A total of 151 country-years of data, including 126 543 070 births across 15 countries from 2000 to 2020, were compiled. Births were categorised into SGA, AGA and LGA using INTERGROWTH-21st standards. Gestation-specific stillbirth rates, with total births as the denominator, and gestation-specific stillbirth risks, with fetuses still in utero as the denominator, were calculated from 24 to 44 weeks of gestation. Gestation-specific stillbirth rates and risks according to size at birth. The overall stillbirth rate was 4.22 per 1000 total births (95% CI 4.22-4.23) across all gestations. Applying the birth-based approach, the stillbirth rates were highest at 24 weeks of gestation, with 621.6 per 1000 total births (95% CI 620.9-622.2) for SGA pregnancies, 298.4 per 1000 total births (95% CI 298.1-298.7) for AGA pregnancies and 338.5 per 1000 total births (95% CI 337.9-339.0) for LGA pregnancies. Applying the fetuses-at-risk approach, the gestation-specific stillbirth risk was highest for SGA pregnancies (1.3-1.4 per 1000 fetuses at risk) prior to 29 weeks of gestation. The risk remained stable between 30 and 34 weeks of gestation, and then increased gradually from 35 weeks of gestation to the highest rate of 8.4 per 1000 fetuses at risk (95% CI 8.3-8.4) at ≥42 weeks of gestation. The stillbirth risk ratio (RR) was consistently high for SGA compared with AGA pregnancies, with the highest RR observed at ≥42 weeks of gestation (RR 9.2, 95% CI 15.2-13.2), and with the lowest RR observed at 24 weeks of gestation (RR 3.1, 95% CI 1.9-4.3). The stillbirth RR was also consistently high for SGA compared with AGA pregnancies across all countries, with national variability ranging from RR 0.70 (95% CI 0.43-0.97) in Mexico to RR 8.6 (95% CI 8.1-9.1) in Uruguay. No increased risk for LGA pregnancies was observed. Small for gestational age (SGA) was strongly associated with stillbirth risk in this study based on high-quality data from high- and middle-income countries. The highest RRs were seen in preterm gestations, with two-thirds of the stillbirths born as preterm births. To advance our understanding of stillbirth, further analyses should be conducted using high-quality data sets from low-income settings, particularly those with relatively high rates of SGA.

Intramyometrial and intravenous oxytocin compared to intravenous carbetocin for prevention of postpartum hemorrhage in elective cesarean section-A quasi-randomized controlled phase IV non-inferiority interventional trial.

Our objective was to assess non-inferiority of the unique approach used in our institution of combined 10 IU IM (intramyometrial) and 10 IU IV (intravenous) oxytocin to carbetocin IV in preventing severe postpartum blood loss in elective cesarean sections. The design was a prospective controlled phase IV non-inferiority interventional trial. The setting was a tertiary center at University Hospital, Zurich, Switzerland. The population consisted of 550 women undergoing elective cesarean section after 36 completed weeks of gestation at low risk for postpartum hemorrhage (PPH). Participants were assigned to either combined oxytocin regimen (10 IU IM and 10 IU IV) or carbetocin (100 μg IV). Non-inferiority for oxytocin for severe PPH was assessed with a 0.05 margin using the Newcombe-Wilson score method. The main outcome measures were severe postpartum blood loss defined as delta hemoglobin (∆Hb, Hb prepartum-Hb postpartum) ≥30 g/L. Non-inferiority of combined oxytocin (IM/IV) in preventing severe postpartum blood loss was not shown (17 women in the oxytocin group vs. 7 in the carbetocin group). The number needed to treat when using carbetocin was 28. The risk difference for ∆Hb ≥30 g/L was 0.04 (oxytocin 0.06 vs. 0.03), 95% confidence interval (CI) (0.00-0.08). No significant difference was observed for ∆Hb (median 12 [IQR 7.0-19.0] vs. 11 [5.0-17.0], p = 0.07), estimated blood loss (median 500 [IQR 400-600] vs. 500 [400-575], p = 0.38), or the PPH rate defined as estimated blood loss ≥1000 mL (12[4.5] vs. 5 [2.0], risk difference 0.03, 95% CI (-0.01 to 0.06), p = 0.16). More additional uterotonics were administered in the oxytocin group compared to the carbetocin group (15.2% vs. 5.9%, p = 0.001). Total case costs were non-significantly different in the oxytocin group (US $ 10 146 vs. 9621, mean difference 471.4, CI (-476.5 to 1419.3), p = 0.33). Combined (IM/IV) oxytocin is not non-inferior to carbetocin regarding severe postpartum blood loss defined as postpartum Hb decrease ≥30 g/L in elective cesarean sections. We recommend carbetocin for use in clinical practice for elective cesarean sections.

Recommendations for data collection in cohort studies of preterm born individuals - The RECAP Preterm Core Dataset.

Preterm birth (before 37 completed weeks of gestation) is associated with an increased risk of adverse health and developmental outcomes relative to birth at term. Existing guidelines for data collection in cohort studies of individuals born preterm are either limited in scope, have not been developed using formal consensus methodology, or did not involve a range of stakeholders in their development. Recommendations meeting these criteria would facilitate data pooling and harmonisation across studies. To develop a Core Dataset for use in longitudinal cohort studies of individuals born preterm. This work was carried out as part of the RECAP Preterm project. A systematic review of variables included in existing core outcome sets was combined with a scoping exercise conducted with experts on preterm birth. The results were used to generate a draft core dataset. A modified Delphi process was implemented using two stages with three rounds each. Three stakeholder groups participated: RECAP Preterm project partners; external experts in the field; people with lived experience of preterm birth. The Delphi used a 9-point Likert scale. Higher values indicated greater importance for inclusion. Participants also suggested additional variables they considered important for inclusion which were voted on in later rounds. An initial list of 140 data items was generated. Ninety-six participants across 22 countries participated in the Delphi, of which 29% were individuals with lived experience of preterm birth. Consensus was reached on 160 data items covering Antenatal and Birth Information, Neonatal Care, Mortality, Administrative Information, Organisational Level Information, Socio-economic and Demographic information, Physical Health, Education and Learning, Neurodevelopmental Outcomes, Social, Lifestyle and Leisure, Healthcare Utilisation and Quality of Life. This core dataset includes 160 data items covering antenatal care through outcomes in adulthood. Its use will guide data collection in new studies and facilitate pooling and harmonisation of existing data internationally.

High protein intake on later outcomes in preterm children: a systematic review and meta-analysis

Abstract Background Appropriate protein intake is crucial for growth and development in children born preterm. We assessed the effects of high (HP) versus low protein (LP) intake on neurodevelopment, growth, and biochemical anomalies in these children. Methods Randomised and quasi-randomised trials providing protein to children born preterm (&lt;37 completed weeks of gestation) were searched following PRISMA guideline in three databases and four registers (PROSPERO registration CRD42022325659). Random-effects model was used for assessing the effects of HP (≥3.5 g/kg/d) vs. LP (&lt;3.5 g/kg/d). Results Data from forty-four studies (n = 5338) showed HP might slightly reduce the chance of survival without neurodisability at ≥12 months (four studies, 1109 children, relative risk [RR] 0.95 [95% CI 0.90, 1.01]; P = 0.13; low certainty evidence) and might increase risk of cognitive impairment at toddler age (two studies; 436 children; RR 1.36 [0.89, 2.09]; P = 0.16; low certainty evidence). At discharge or 36 weeks, HP intake might result in higher weight and greater head circumference z-scores. HP intake probably increased the risk of hypophosphatemia, hypercalcemia, refeeding syndrome and high blood urea, but reduced risk of hyperglycaemia. Conclusions HP intake for children born preterm may be harmful for neonatal metabolism and later neurodisability and has few short-term benefits for growth. Impact statement Planned high protein intake after birth for infants born preterm might be harmful for survival, neurodisability and metabolism during infancy and did not improve growth after the neonatal period. Protein intake ≥3.5 g/kg/d should not be recommended for children born preterm.

IL-1 and TNF mediates IL-6 signaling at the maternal-fetal interface during intrauterine inflammation.

IL6 signaling plays an important role in triggering labor and IL6 is an established biomarker of intrauterine infection/inflammation (IUI) driven preterm labor (PTL). The biology of IL6 during IUI at the maternal-fetal interface was investigated in samples from human subjects and non-human primates (NHP). Pregnant women with histologic chorioamnionitis diagnosed by placenta histology were recruited (n=28 term, n=43 for preterm pregnancies from 26-36 completed weeks of gestation). IUI was induced in Rhesus macaque by intraamniotic injection of lipopolysachharide (LPS, n=23). IL1 signaling was blocked using Anakinra (human IL-1 receptor antagonist, n=13), and Tumor necrosis factor (TNF) signaling was blocked by anti TNF-antibody (Adalimumab n=14). The blockers were given before LPS. All animals including controls (intraamniotic injection of saline n=27), were delivered 16h after LPS/saline exposure at about 80% gestation. IUI induced a robust expression of IL6 mRNAs in the fetal membranes (chorion-amnion-decidua tissue) both in humans (term and preterm) and NHP. The major sources of IL6 mRNA expression were the amnion mesenchymal cells (AMC) and decidua stroma cells. Additionally, during IUI in the NHP, ADAM17 (a protease that cleaves membrane bound IL6 receptor (IL6R) to release a soluble form) and IL6R mRNA increased in the fetal membranes, and the ratio of IL6 and soluble forms of IL6R, gp130 increased in the amniotic fluid signifying upregulation of IL6 trans-signaling. Both IL1 and TNF blockade suppressed LPS-induced IL6 mRNAs in the AMC and variably decreased elements of IL6 trans-signaling. These data suggest that IL1 and TNF blockers may be useful anti-inflammatory agents via suppression of IL6 signaling at the maternal-fetal interface.

Ambient PM2.5, household environment and preterm birth: A birth cohort study in Shandong, China

BackgroundThe associations between fine particulate matter with an aerodynamic diameter of 2.5 μm or less (PM2.5) and risk of preterm birth (PTB) are inconsistent, and the effect of household environment on PTB is largely unclear. AimTo investigate the association of ambient PM2.5 throughout pregnancy, household environmental factors and PTB, with further exploration of their potential interaction and joint effect on PTB. MethodsThe study included 5888 pregnant women between 2018 and 2021 in Weifang Maternal and Child Health hospital of Shandong, China. Maternal exposure to PM2.5 was extracted from ChinaHighAirPollutants datasets according to individual home address. Household environmental information including residential floor level, double-glazed window, heating fuel, cooking, smoking and window ventilation was collected by questionnaires at enrollment. PTB was defined as a birth before 37 completed weeks of gestation. General additive models were applied to examine the associations of PM2.5 exposure, household environment and PTB. ResultsOne-unit increase of PM2.5 throughout pregnancy was associated with significantly increased risk of PTB (OR = 1.069, 95% CI: 1.037, 1.103). In contrast, installation of double-glazed windows (OR = 0.763, 95% CI: 0.589, 0.990) and residential floor level of the 5th floor or above (OR = 0.746, 95% CI: 0.583, 0.955) were found to be associated with significantly reduced risk of PTB. The stratified analyses demonstrated that the protective associations remained among those with high PM2.5 exposure, urban residence, middle SES level and cesarean delivery. A negative interaction between residential floor level and PM2.5 exposure on PTB, and joint effect of installation of double-glazed windows plus residential floor level of the 5th floor or above on PTB were observed. ConclusionsThis study found the adverse effect of PM2.5 during the pregnancy on PTB, and identified protective associations between installing double-glazed windows, living on the 5th floor or above and PTB in relatively polluted regions.

Neurodevelopmental outcome of pre-term babies less than 34 weeks of gestation at corrected 2 years of age, with respect to their antenatal steroid status

Objectives: The objective of this study was to determine the neurodevelopmental status of pre-term babies between &lt;34 weeks of gestation and equal to or more than 25 weeks of gestation, at corrected 2 years of age with respect to their antenatal steroid status. Materials and Methods: This population-level prospective study was conducted over a period of 6 years from 2017 to 2023 in middle Kerala. Pre-term babies with gestational age at birth between &lt;34 weeks and equal to or more than 25 completed weeks, presenting for follow-up within 3 months of delivery, were randomly enrolled for the study. A total of 150 children were followed up and neurodevelopmental assessment done using Bayley Scales of Infant and Toddler Development edition-3 at their corrected 2 years of age. Approval for this prospective observational study was obtained from the Institutional Ethics Committee, School of Behavioral Sciences, Mahatma Gandhi University, Kottayam, Kerala, dated September 22, 2017. Results: Eighty-one pre-term &lt;34 weeks babies belonged to the antenatal steroid complete group, 40 pre-term &lt;34 weeks babies belonged to the antenatal steroid partial group, and 29 pre-term &lt;34 weeks babies belonged to the nil steroid group. Total neurodevelopmental status score and domain-wise, cognitive, language, motor, and social-emotional developmental scores show significantly higher scores for pre-term &lt;34 weeks with antenatal history of complete course steroid administered before pre-term delivery compared to partial and nil antenatal steroid group. Conclusions: Antenatal steroids are having a significant impact on the overall neurodevelopmental outcome of pre-term babies equal to or more than 25 weeks of gestation and &lt;34 weeks of gestation, at their corrected 2 years of age, the maximum benefit for complete antenatal steroid group pre-term babies, equal to or more than 25 weeks and &lt;34 completed weeks of gestation when compared with pre-term babies, equal to or more than 25 weeks and &lt;34 completed weeks of gestation without any antenatal steroids.

Prenatal ochratoxin A exposure, birth outcomes and infant growth in rural Burkina Faso: A human biomonitoring sub-study from the MISAME-III trial

Mycotoxin exposure during pregnancy has been associated with adverse birth outcomes and poor infant growth in low- and middle-income countries. We assessed multiple biomarkers and metabolites of exposure to mycotoxins during pregnancy and their associations with birth outcomes and infant growth in 305 pregnant participants, between 30 and 34 completed weeks of gestation, in rural Burkina Faso. In this study, whole blood microsamples were analyzed for mycotoxin concentrations using ultra-performance liquid chromatography coupled to tandem mass spectrometry. Unadjusted and adjusted associations between mycotoxin exposure, and birth outcomes and infant growth at 6 months were estimated using linear regression models for continuous outcomes and linear probability models with robust variance estimation for binary outcomes. Infant growth trajectories from birth to 6 months were compared by exposure status using mixed-effects models with random intercept for the individual infant and random slope for the infant's age. Ochratoxin A (OTA) exposure was detected in 50.8 % of the study participants, with aflatoxin G1, aflatoxin M1, cyclopiazonic acid, deoxynivalenol and T-2-toxin being detected in the range of 0.33 % and 2.31 % of the population. We found no statistically significant (p ≥ 0.05) associations between OTA exposure, and birth outcomes and infant growth. Despite this, the findings indicate a significant presence of ochratoxin A among pregnant participants. Public health policies and nutrition-sensitive interventions must ensure that OTA exposure is reduced in Burkina Faso.

Pregnancy complicated by small cell neuroendocrine carcinoma of the cervix

Small cell neuroendocrine carcinoma of the cervix (SCNCC) is considered to be an extremely rare, highly invasive and aggressive subtype of squamous cell carcinoma. It is particulary rare during pregnancy. Here we report a case in which a 32-year-old patient who was admitted to our Department at 27 completed weeks of gestation with intermittent vaginal spotting and a large amount of malodorous vaginal discharge. Gynecological examination revealed a 2 cm exophytic polypoid tumor coming out of the cervix. On rectal examination there was no clinically evident parametrial invasion. Biopsy of the cervix was performed and the diagnosis of small cell neuroendocrine carcinoma was established. We reviewed and discussed the features, diagnosis, treatment and prognosis of SCNCC diagnosed during pregnancy.

Risk factors for spontaneous preterm deliveries above twenty-eight complete weeks of gestation

Purpose: To identify risk factors for spontaneous preterm delivery (SPD) given that it is associated with high neonatal morbidity and mortality. Material and methods: This case-control study was carried out between 1st February and 31st July 2021. Women who delivered spontaneously between 28 and ˂37 weeks (cases) or at ≥37 weeks (controls) were recruited. The main variables recorded included maternal age and parity, inter-pregnancy interval, if the pregnancy was intended, medical, obstetrical and family past-histories, gestational age at delivery, number of gestation and pathologies during current gestation. Fisher exact test, t-test and logistic regression were used for comparison. P&lt;0.05 was considered statistically significant. Results: Our frequency of preterm delivery was 15.3% (116/759 births), with 9.9% (75/759) being SPD. Significant risk factors for SPD were premature rupture of membranes (aOR 19.96, 95%CI 11.04-45.82), inter-pregnancy interval ˃60 months (aOR 13.02, 95%CI 6.11-33.01), Nulliparity (aOR 10.21, 95%CI 5.72-21.31), 1st degree family history of SPD (aOR 7.73, 95%CI 1.54-11.39), malaria in the 3rd trimester (aOR 6.89, 95%CI 2.15-8.63), multiple pregnancies (aOR 6.43, 95%CI 3.21-9.79), severe anemia (Hb ˂6g/dl) in the 3rd trimester (aOR 5.73, 95%CI 2.04-10.60) and unintended pregnancies (aOR 2.44, 95%CI 1.98-7.88). Conclusion: Women with multiple or unintended pregnancies and those with the pre-gestational risk factors identified above should be well followed up during pregnancy to allow prevention, if not, early diagnosis of SPD. Moreover, prevention of the above-identified pathologies in pregnancy is mandatory if we want to reverse the rate of SPD

Outcomes of Premature Rupture of Membrane Among Women Admitted in Teaching Hospital, Chitwan, Nepal

Background: Premature rupture of membranes is defined as rupture of membranes after 28th weeks of gestation before the onset of labor is called preterm PROM when it occurs after 37 completed weeks of gestation and before onset of labor, then it is term PROM. Spontaneous rupture of the membrane any time beyond 28th weeks of pregnancy but before the onset of labor is called Premature Rupture of Membrane (PROM). The management of maternal and fetal outcome in PROM is very important to decrease maternal as well as neonatal mortality and for better management and prevention of complications which has essential significance for the further fate pregnancy. Thus, the study aims to find out the factors and outcomes of PROM among the women who will be admitted in maternity ward at Chitwan Medical College. Methods: A descriptive cross-sectional study was conducted in a teaching hospital of Chitwan, Nepal during the study period of six months from 13th Feb 2023 to 14th August 2023 after getting ethical approval from Chitwan Medical College- institutional Review Committee (Reference number-CMC-IRC/079/080). Women were selected via convenience sampling technique. Face to face interview was conducted to gather socio-demographic and obstetric data by structured interview schedule whereas, data related to the feto maternal outcomes were obtained from patient charts and delivery record books. Statistical Package for Social Sciences version 20 was used for data analysis. Point estimate at 95% confidence interval was calculated along with frequency and proportion for binary data. Result: The prevalence of premature rupture of membrane was found to be 15.3% out of 503 delivered mothers during six-month period. More than half (67.5%) of postnatal mother were between age of 35-45 years. More than half (57.1%) of mother were at 33-35weeks of gestation. Only 3.9 % of mother has Postpartum hemorrhage as maternal outcome. Only 2.6% of fetus have meconium aspiration syndrome as fetus outcome. Conclusion: The burden of premature rupture of membrane was found quite higher as compared to other similar studies done in Nepal. Hence, awareness, early screening, and treatment are necessary for the hospital attended pregnant women to minimize the risk of premature rupture of membrane.

Maternal Acylcarnitine Disruption as a Potential Predictor of Preterm Birth in Primigravida: A Preliminary Investigation.

Preterm birth, defined as any birth before 37 weeks of completed gestation, poses adverse health risks to both mothers and infants. Despite preterm birth being associated with several risk factors, its relationship to maternal metabolism remains unclear, especially in first-time mothers. Aims of the present study were to identify maternal metabolic disruptions associated with preterm birth and to evaluate their predictive potentials. Blood was collected, and the serum harvested from the mothers of 24 preterm and 42 term births at 28-32 weeks gestation (onset of the 3rd trimester). Serum samples were assayed by untargeted metabolomic analyses via liquid chromatography/mass spectrometry (QTOF-LC/MS). Metabolites were annotated by inputting the observed mass-to-charge ratio into the Human Metabolome Database (HMDB). Analysis of 181 identified metabolites by PLS-DA modeling using SIMCA (v17) showed reasonable separation between the two groups (CV-ANOVA, p = 0.02). Further statistical analysis revealed lower serum levels of various acyl carnitines and amino acid metabolites in preterm mothers. Butenylcarnitine (C4:1), a short-chain acylcarnitine, was found to be the most predictive of preterm birth (AUROC = 0.73, [CI] 0.60-0.86). These observations, in conjuncture with past literature, reveal disruptions in fatty acid oxidation and energy metabolism in preterm primigravida. While these findings require validation, they reflect altered metabolic pathways that may be predictive of preterm delivery in primigravida.
