RESUMO

OBJECTIVE: Our aim was to assess diagnostic accuracy in the prediction of small for gestational age (SGA <10th centile) and fetal growth restricted (FGR) (SGA <3rd centile) fetuses using three different sonographic methods in pregnancies at increased risk of fetal growth restriction: 1) fetal abdominal circumference (AC) z-scores, 2) estimated fetal weight (EFW) z-scores according to postnatal reference standard; 3) EFW z-scores according to a prenatal reference standard. METHODS: Singleton pregnancies at increased risk of fetal growth restriction seen in two university hospitals between 2014 and 2015 were studied retrospectively. EFW was calculated using formulas proposed by the INTERGROWTH-21st project and Hadlock; data derived from publications by the INTEGROWTH-twenty-first century project and Hadlock were used to calculate z-scores (AC and EFW). The accuracy of different methods was calculated and compared. RESULTS: The study group included 406 patients. Prenatal standard EFW z-scores derived from INTERGROWTH-21st project and Hadlock and co-workers performed similarly and were more accurate in identifying SGA infants than using AC z-scores or a postnatal reference standard. The subgroups analysis demonstrated that EFW prenatal standard was more or similarly accurate compared to other methods across all subgroups, defined by gestational age and birth weight. CONCLUSIONS: Prenatal standard EFW z-scores derived from either INTERGROWTH-21 st project or Hadlock and co-workers publications demonstrated a statistically significant advantage over other biometric methods in the diagnosis of SGA fetuses.

RESUMO

BACKGROUND: The single vitrified-warmed blastocyst transfer (SVBT) cycle has been increasingly utilized for assisted reproductive technology. Women of advanced maternal age (AMA) comprise a significant portion of patients who have undergone 'freeze-all' cycles. This study investigated the association between the post-warming extended culture duration and pregnancy outcomes in patients of AMA. METHODS: This retrospective cohort study analyzed the outcomes of 697 SVBT cycles between January 2016 and December 2017. The cycles were divided into 3 groups based on the age of the female partners: group I: < 35 years (n = 407), group II: 35-37 years (n = 176); and group III, 38-40 years (n = 114). Data are shown as the mean ± standard error of the mean. Data were analyzed using one-way ANOVA followed by Duncan's multiple range test. Statistical significance was set at P < 0.001. RESULTS: The blastocyst rate, clinical pregnancy rate, and live birth rate (LBR) was significantly lower in the AMA groups. However, there were no significant differences in LBR in the transfer between the AMA and younger groups according to blastocyst morphology and post-warming extended culture duration. CONCLUSION: Post-warming extended culture of blastocysts is not harmful to patients of AMA. It could be a useful parameter in clinical counseling and decision making for fertility treatments.

RESUMO

BACKGROUND AND PURPOSE: The aim of this study was to define the prevalence of pre-eclampsia, gestational hypertension (HT), chronic HT, and gestational diabetes during pregnancy in a defined population of patients with saccular intracranial aneurysms (sIAs). METHODS: We included all patients with sIA, first admitted to the Neurosurgery Department of Kuopio University Hospital from its defined catchment population between 1990 and 2015, who had given birth for the first time in 1990 or later. The patients' medical records were reviewed, and clinical data were linked with prescription drug usage, hospital diagnoses and causes of death, obtained from nationwide registries. The prevalences of pre-eclampsia, other hypertensive disorders and gestational diabetes in patients were compared with a matched control population (n = 324). In addition, the characteristics of sIA disease in patients with pre-eclampsia were compared to those of sIA patients without pre-eclampsia. RESULTS: A total of 169 patients with sIA fulfilled the inclusion criteria. Of these, 22 (13%) had pre-eclampsia and 32 (19%) had other hypertensive disorders during pregnancy. In 324 matched controls who had given birth, the prevalence of pre-eclampsia was 5% (n = 15) and other hypertensive disorders were diagnosed in 10% (n = 34). There was no significant difference in prevalence of gestational diabetes (12% vs. 11%). Patients with sIA with pre-eclampsia more frequently had irregularly shaped aneurysms (p = 0·003). CONCLUSIONS: Pre-eclampsia was significantly more frequent in patients with sIA than in their population controls. Irregularly shaped aneurysms were more frequent in sIA patients with pre-eclampsia. Further studies are required to determine whether history of pre-eclampsia may indicate an elevated risk for sIA formation or rupture.

RESUMO

Sperm DNA damage is considered a predictive factor for the clinical outcomes of patients undergoing ART. Laboratory evidence suggests that zygotes and developing embryos have adopted specific response and repair mechanisms to repair DNA damage of paternal origin. We have conducted a systematic review in accordance with guidelines from Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to identify and review the maternal mechanisms used to respond and repair sperm DNA damage during early embryonic development, how these mechanisms operate and their potential clinical implications. The literature search was conducted in Ovid MEDLINE and Embase databases until May 2021. Out of 6297 articles initially identified, 36 studies were found to be relevant through cross referencing and were fully extracted. The collective evidence in human and animal models indicate that the early embryo has the capacity to repair DNA damage within sperm by activating maternally driven mechanisms throughout embryonic development. However, this capacity is limited and likely declines with age. The link between age and decreased DNA repair capacity could explain decreased oocyte quality in older women, poor reproductive outcomes in idiopathic cases and patients who present high sperm DNA damage. Ultimately, further understanding mechanisms underlying the maternal repair of sperm DNA damage could lead to the development of targeted therapies to decrease sperm DNA damage, improved oocyte quality to combat incoming DNA insults or lead to development of methodologies to identify individual spermatozoa without DNA damage.

RESUMO

INTRODUCTION: To evaluate whether the incidence of hypertensive disorders of pregnancy (HDP) in pregnant women was related to endometriosis (EM), ovulation and embryo vitrification technology. METHODS: A retrospective cohort study was conducted on the clinical data of 3674 women who were treated with IVF / ICSI in the Reproductive Medicine Center of the First Affiliated Hospital of Sun Yat-sen University and maintained clinical pregnancy for more than 20 weeks. All pregnancies were followed up until the end of pregnancy. The follow-up consisted of recording the course of pregnancy, pregnancy complications, and basic situation of newborns. RESULTS: Compared with NC-FET without EM, HRT-FET without EM was found to have a higher incidence of HDP during pregnancy (2.7% V.S. 6.1%, P<0.001); however, no significant difference was found in the incidence of HDP between NC-FET and HRT-FET combined with EM (4.0% V.S. 5.7%, P>0.05). In total frozen-thawed embryo transfer (total-FET), the incidence of HDP in the HRT cycle without ovulation (HRT-FET) was observed to be higher than that in the NC cycle with ovulation (NC-FET) (2.8% V.S. 6.1%, P<0.001). In patients with EM, no significant difference was found in the incidence of HDP between fresh ET and NC-FET (1.2% V.S. 4.0%, P>0.05). CONCLUSION: EM does not seem to have an effect on the occurrence of HDP in assisted reproductive technology. During the FET cycle, the formation of the corpus luteum may play a protective role in the occurrence and development of HDP. Potential damage to the embryo caused by cryopreservation seems to have no effect on the occurrence of HDP.

RESUMO

Examining how spatial access to health care varies across geography is key to documenting structural inequalities in the United States. In this article and the accompanying StoryMap, our team identified ZIP Code Tabulation Areas (ZCTAs) with the largest share of minoritized racial and ethnic populations and measured distances to the nearest hospital offering emergency services, trauma care, obstetrics, outpatient surgery, intensive care, and cardiac care. In rural areas, ZCTAs with high Black or American Indian/Alaska Native representation were significantly farther from services than ZCTAs with high White representation. The opposite was true for urban ZCTAs, with high White ZCTAs being farther from most services. These patterns likely result from a combination of housing policies that restrict housing opportunities and federal health policies that are based on service provision rather than community need. The findings also illustrate the difficulty of using a single metric-distance-to investigate access to care on a national scale.

RESUMO

The aim of the study was to evaluate the effects of thyroperoxidase antibody (TPOAb) and thyroglobulin antibody (TgAb) on maternal and neonatal adverse outcomes in pregnant women. A total of 296 singleton pregnant women were classified into four groups according to the thyroid auto-antibody in the first trimester. Finally, there were 97 women in TPOAb positive group (TPOAb+/TgAb-), 35 in TgAb positive group (TPOAb-/TgAb+), 85 in TPOAb and TgAb positive group (TPOAb+/TgAb+), and 79 in TPOAb and TgAb negative group (TPOAb-/TgAb-). Thyroid function, TPOAb, and TgAb were checked during pregnancy and followed up at 6 weeks, 3 months, 6 months, 9 months, and 12 months postpartum. Levothyroxine sodium tablets could be taken to maintain euthyroid antepartum. Thyroid function of women with postpartum thyroiditis (PPT) were followed up at 2 and 3 years postpartum. We observed the incidence of PPT, premature rupture of membranes (PROM), placental abruption, placenta previa, polyhydramnios, oligohydramnios, postpartum hemorrhage, preterm birth, and low birth Weight in the four groups. 19.93% of the women had PPT. The incidence of PPT in TPOAb+/TgAb-, TPOAb-/TgAb+, TPOAb+/TgAb+groups was significantly higher than that in TPOAb-/TgAb- group, respectively (16.49 vs. 6.33%, 22.86 vs. 6.33%, 35.29 vs. 6.33%, p <0.05). The incidence of PPT in TPOAb+/TgAb+group was significantly higher than that in TPOAb+/TgAb- group (35.29 vs. 16.49%, p <0.01). PPT occurred as early as 6 weeks postpartum, but mainly at 3 and 6 months postpartum in the four groups (62.50%, 75.00%, 70.00%, 80.00%). All PPT in TPOAb-/TgAb- group occurred within 6 months postpartum, while it was found at 9 months or 12 months postpartum in other three groups. There was no classical form of PPT in TPOAb-/TgAb- group, while in the other three groups, all three types (classical form, isolated thyrotoxicosis, isolated hypothyroidism) existed. At 2 years postpartum of the women with PPT, the rate of euthyroidism in TPOAb+/TgAb+group was significantly lower than that in TPOAb-/TgAb- group (p <0.05). At 3 years postpartum of the women with PPT, the rate of euthyroidism in TPOAb+/TgAb-, TPOAb-/TgAb+, and TPOAb+/TgAb+groups were significantly lower than that in TPOAb-/TgAb- group (p <0.05). The values of TPOAb and TgAb postpartum were significantly higher than those during pregnancy (p <0.05). The incidence of PROM in TPOAb+/TgAb- group was significantly higher than that in TPOAb-/TgAb- group (32.99 vs. 17.72%, p <0.05). The binary logistic regression for PPT showed that the OR value of TPOAb was 2.263 (95% CI 1.142-4.483, p=0.019). The OR value of TgAb was 3.112 (95% CI 1.700-5.697, p=0.000). In conclusion, pregnant women with positive thyroid auto-antibodies had an increased risk of PPT and a reduced rate of euthyroidism at 2 and 3 years postpartum. TPOAb is associated with the incidence of PROM. Both of TPOAb and TgAb were independent risk factors for PPT. TgAb deserves more attention when studying autoimmune thyroid disease (AITD) combined with pregnancy.

RESUMO

BACKGROUND: Sonography based estimate of fetal weight is a considerable issue for delivery planning. The study evaluated the influence of diabetes, obesity, excess weight gain, fetal and neonatal anthropometrics on accuracy of estimated fetal weight with respect to the extent of the percent error of estimated fetal weight to birth weight for different categories. METHODS: Multicenter retrospective analysis from 11,049 term deliveries and fetal ultrasound biometry performed within 14 days to delivery. Estimated fetal weight was calculated by Hadlock IV. Percent error from birth weight was determined for categories in 250 g increments between 2500 g and 4500 g. Estimated fetal weight accuracy was categorized as accurate ≤ 10% of birth weight, under- and overestimated by > ± 10% - ± 20% and > 20%. RESULTS: Diabetes was diagnosed in 12.5%, obesity in 12.6% and weight gain exceeding IOM recommendation in 49.1% of the women. The percentage of accurate estimated fetal weight was not significantly different in the presence of maternal diabetes (70.0% vs. 71.8%, p = 0.17), obesity (69.6% vs. 71.9%, p = 0.08) or excess weight gain (71.2% vs. 72%, p = 0.352) but of preexisting diabetes (61.1% vs. 71.7%; p = 0.007) that was associated with the highest macrosomia rate (26.9%). Mean percent error of estimated fetal weight from birth weight was 2.39% ± 9.13%. The extent of percent error varied with birth weight with the lowest numbers for 3000 g-3249 g and increasing with the extent of birth weight variation: 5% ± 11% overestimation in the lowest and 12% ± 8% underestimation in the highest ranges. CONCLUSION: Diabetes, obesity and excess weight gain are not necessarily confounders of estimated fetal weight accuracy. Percent error of estimated fetal weight is closely related to birth weight with clinically relevant over- and underestimation at both extremes. This work provides detailed data regarding the extent of percent error for different birth weight categories and may therefore improve delivery planning.

RESUMO

The purpose of this study was to highlight the possible effects on the hippocampus of the electromagnetic field (EMF) emitted by mobile phones, and to investigate whether these potential effects can be reduced using various antioxidant substances. Twenty-seven female Wistar albino rats were divided into nine equal groups, each containing three pregnant rats aged 8-10 weeks and weighing 200-250 gr. The EMF groups were exposed to 900 Megahertz (MHz) EMF for 1 h (hr) a day for 21 days. No EMF exposure was applied to the Cont and also the groups given only Garcinia kola (GK), Momordica charantia (MC), and thymoquinone (TQ). The Sham group was kept in the polycarbonate EMF exposure system, but was not exposed to EMF. Four weeks after birth, rat pups were subjected to behavioural tests. Brain tissue samples were evaluated using histological, stereological, functional, and immunohistochemical methods. The numbers of pyramidal neurons in the rat cornu ammonis (CA) were determined using the optical fractionator method. Superoxide dismutase (SOD) and catalase (CAT) enzyme activities in the blood samples were also evaluated. The analysis data indicated that total pyramidal neuron numbers were decreased significantly in the CA of the EMF (1 hr) group (p < 0.01). Our results also showed that the protective effect of MC was more potent than that of the other antioxidant substances (p < 0.01). A 900 MHz EMF can cause deleterious changes in the brain. It can also be suggested that GK, MC and TQ are capable of reducing these adverse effects.

RESUMO

OBJECTIVE: Pregnant women may develop disseminated intravascular coagulation (DIC), possibly resulting in massive maternal haemorrhage and perinatal death. The Japan guideline recommends use of antithrombin III (ATIII) for DIC in obstetrics; however, its effect remains uncertain. The present study aimed to investigate the effect of ATIII for DIC in obstetrics, using a national inpatient database in Japan. DESIGN: Nationwide observational study. SETTING: Japan. POPULATION: We used the Diagnosis Procedure Combination inpatient database to identify patients who delivered at hospital and were diagnosed with DIC from July 2010 to March 2018. METHODS: Propensity score matching analyses were performed to compare in-hospital maternal mortality and hysterectomy during hospitalisation between users and non-users of ATIII on the day of delivery. MAIN OUTCOME MEASURES: In-hospital mortality, hysterectomy. RESULTS: A total of 9920 patients were enrolled, including 4329 patients (44%) who used ATIII and 5511 patients (56%) who did not use ATIII. One-to-one propensity score matching created 3290 pairs. In-hospital maternal mortality did not differ significantly between the propensity-matched groups (0.3% in the ATIII group versus 0.5% in the control group; odds ratio 0.73; 95% CI 0.35-1.54). A significantly lower proportion of patients in the ATIII group, compared with those in the control group, underwent hysterectomy during hospitalisation (5.3% versus 8.7%; absolute risk difference -2.9%; 95% CI -4.2 to -1.6%). CONCLUSIONS: Although the present study did not show a mortality-reducing effect of ATIII for patients with DIC in obstetrics, it may have clinical benefit in terms of reducing the number of patients undergoing hysterectomy. TWEETABLE ABSTRACT: This study did not show mortality-reducing effect of antithrombin III for patients with DIC in obstetrics.

RESUMO

BACKGROUND The retroperitoneal hematoma is a very rare entity in obstetrics. A type of obstetric hematoma that extends into the retroperitoneal space, this hematoma usually occurs after laceration of the uterine artery, after uterine rupture, or by extension of a vaginal hematoma. Although the hematoma usually manifests as intense abdominal pain, sometimes the clinical signs can go unnoticed. This is the main reason it is important to report the cases in which retroperitoneal hematomas occur. In addition to clinical suspicion, experience in management can also help improve maternal morbidity and mortality from this cause. CASE REPORT We present a series of 3 clinical cases in which retroperitoneal hematomas occurred after instrumental deliveries. The 3 clinical cases described took place before the COVID-19 pandemic. In the first 2 deliveries, a vacuum was used, while in the third delivery, spatulas were used. CONCLUSIONS Our findings showed that suspicion is essential in patients with symptoms of nonspecific pain, as well as in patients with anemia that causes hemodynamic instability in the immediate postpartum period. The use of early computed tomography angiography in hemodynamically stable patients is essential to reach a diagnosis and to determine if the patient can be treated by embolization of the bleeding vessel.

RESUMO

Wasting among infants and young children in underdeveloped countries including Ethiopia is one of the most serious public health issues. Therefore, this study was designed to assess the magnitude of wasting and the variables that associate with it among infants and young children in the Kuyu district of Northern Oromia, Ethiopia. A community-based cross-sectional study of 612 infants and young children aged 6-23 months was conducted. To select eligible infants and young children from each family in the Kuyu district, a multilevel sampling approach was used. The amount and determinants related to wasting were investigated using the Statistical Package for Social Sciences (SPSS) version 20.0. In the study area, 14.1% of infants and young children were found to be wasting. Maternal educational status (AOR = 1.8, 95% CI; 1.01, 4.32), diarrhoea (AOR = 2.3, 95% CI; 1.98, 4.56), exclusive breastfeeding (AOR = 2.46, 95% CI, 1.4, 4.58), antenatal care visits (AOR = 2.21; 95% CI, 1.32, 3.48), and wealth index (AOR = 1.66, 95% CI; 1.07, 4.47) were significantly associated with wasting. According to the findings of this study, mother educational status, the occurrence of diarrhoea, exclusive breastfeeding, antenatal care visits, and wealth index have an impact on infants and young children's wasting. Therefore, to lower the burden of wasting among infants and young children in the study, community-based schooling and nutritional interventions are urgently needed.

RESUMO

Objective: We aimed to study the relationship between ferroptosis proteins and reproductive outcomes of infertile patients with PCOS and construct the related prognostic model. Methods: These endometrium samples of the study were collected from 33 women with PCOS and 7 control women with successful pregnancies at the Reproductive Center of Lanzhou University Second Hospital, September 2019 to September 2020. The 40 patients' endometrium was identified the differentially expressed proteins (DEPs) using liquid chromatography tandem mass spectrometry. The Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis and Gene Ontology (GO) showed that the DEPs related pathways and functions between PCOS and controls. Subsequently, univariate Cox regression analysis and Lasso regression were used to identifying independent prognostic ferroptosis proteins, which were utilized to establish a prognostic model. Then the performance of the prognostic model was evaluated by receiver operating characteristic curve (ROC) and decision curve analysis (DCA). Then clinical data and prognostic model were used to predict the reproductive outcomes of PCOS patients by constructing the nomograms. Finally, we performed the single sample gene set enrichment analysis (ssGSEA) to explore the correlation between risk scores and immune status. Results: A total of 5331 proteins were identified, 391 proteins were differentially expressed in the PCOS and controls. The KEGG analysis revealed that the ferroptosis pathway was significantly different between PCOS and controls. 5 ferroptosis proteins (GPX4, DPP4, G6PD, PCBP1, and PCBP2) prognostic model (FerSig) was constructed via Cox regression and Lasso regression. Patients were separated into high and low-risk groups according to the FerSig. Kaplan-Meier curve showed that patients in the low-risk group had much better reproductive outcomes than those in the high-risk group. The DCA showed that the risk score was an independent predictive factor for reproductive outcomes. Compared with clinical data, ROC curve analysis indicated the FerSig proteins as a potential diagnostic and prognostic factor in PCOS patients. Functional analysis revealed that the FerSig proteins and immune microenvironment were correlated to the prognosis of PCOS. Conclusion: The prognostic model focused on the FerSig proteins could predict the reproductive outcomes of PCOS patients with decreased endometrial receptivity, and provided theoretical basis for individualized treatment.

RESUMO

Background: Few studies have described the relationship between the type of infertility and live birth in patients treated with intrauterine insemination (IUI). We focused on this issue and attempted to explore it. Methods: This retrospective study enrolled 2,256 infertile patients who underwent their first IUI cycle and were subsequently diagnosed with a clinical pregnancy at Ji'an Women and Child Health Care Hospital between 2007 and 2018. Inductees were divided into primary infertility (1,680 patients) and secondary infertility groups (876 patients). Following 1:1 propensity score matching to obtain balanced data, the COX proportional hazards model, landmark analysis, and subgroup analysis were used to assess the association between infertility types and live birth rates. Subsequently, a sensitivity analysis was employed to evaluate the potential effect of unmeasured confounding on outcomes. Results: Of the 1,486 patients who were identified as a matched cohort, 743 were in the primary infertility group and the remaining patients were in another group. A total of 1,143 patients had live births during 431,009 person-days of follow-up (average 290.0 days). Throughout the follow-up period, patients with secondary infertility demonstrated more live births than patients with primary infertility (hazard ratio [HR], 1.16; 95% confidence interval [CI], 1.04 to 1.30; P = .007). More details were observed in the landmark analysis. Live birth rates were similar in both groups within 316 days of follow-up (HR, 0.84; 95% CI, 0.62 to 1.14; P = .269), whereas the opposite was found between 316 days of follow-up and delivery day (HR, 1.19; 95% CI, 1.06 to 1.34; P = .004). This was also obtained in a subgroup analysis of patients younger than 35 years old and patients treated with natural cycles (NCs) and IUIs. Conclusion: Among the infertile patients who underwent a single natural or stimulated cycle followed by IUI and had later pregnancies, full-term young secondary infertility mothers (<35 years of age) had a greater chance of having viable babies than the primary infertility ones. The latter may get more benefits when undergoing ovarian stimulation and IUI rather than NC-IUI.

RESUMO

Introduction: embryo implantation is a crucial step for assisted reproductive technology (ART) achievement. Human chorionic gonadotropin (hCG) is one of the main regulators of the implantation process. Studies focusing on the impact of intrauterine hCG infusion at the time of embryo transfer on clinical ART outcomes have shown controversial results, mainly at blastocyst stage. In this study, we aimed to investigate whether intrauterine hCG infusion one day before human blastocyst transfer in fresh invitro fertilization (IVF) cycles enhances implantation and pregnancy rates. Methods: a total of 174 subfertile women undergoing autologous fresh blastocyst transfer were enrolled in this randomized prospective study. Patients were randomly divided into three groups; group 1 (n = 54) and group 2 (n = 59) received an intrauterine injection of respectively 500 IU and 1000 IU of hCG one day before blastocyst transfer and the control group (n= 61) did not receive any intrauterine injection. The pregnancy and implantation rates were compared between the three study groups. Results: significant difference was found between the study groups. The bio chemical pregnancy rates were 25.9%, 30.5% and 29.5%, the clinical pregnancy rates were 24.1%, 27.1% and 27.9% and the implantation rates were 14.9%, 17.9% and 18.7% respectively in group 1,2 and control group. Conclusion: our results have shown that clinical outcomes in fresh IVF cycles cannot be improved through intrauterine hCG administration one day prior to blastocyst transfer, neither with 500 IU of hCG nor with a higher dose of 1000 IU of hCG.

RESUMO

Introduction: iron deficiency anaemia (IDA) in pregnancy is a prominent risk factor for maternal mortality and poor pregnancy outcomes in low- and middle-income countries, but studies on the significance of dietary iron intake (DII) in IDA in this population are limited. This study assessed the association of DII with odds of IDA among pregnant women attending primary health centres in Ifako-Ijaiye, Lagos, Nigeria. Methods: sociodemographic information and dietary intakes were assessed among 432 singleton pregnant women (without pre-existing medical complications) using a pre-tested questionnaire and 24 hr-dietary recall, respectively. Dietary iron intake (DII) was derived from the 24 hr-dietary recall using the West African food composition table. Haemoglobin (Hb) levels in blood samples were measured using the haemoglobin-cyanide technique, and IDA was defined using the World Health Organization criteria. Multivariable-adjusted odds ratios (OR) of IDA and 95% confidence intervals (CI) by energy-adjusted tertiles of DII were estimated using logistic regression with a two-sided P<0.05. Results: mean age of respondents was 28.5 ± 4.6 years, and the average gestational age was 31.3 ± 4.1 weeks. Mean DII was 20.3 ± 3.3 mg/day, and Hb concentration was 97.9 ± 12.9 g/L. Furthermore, 83.8% had IDA and multivariable-adjusted OR and 95% CI for odds of IDA across tertiles of energy-adjusted DII were 1.00, 0.32 (0.05, 1.77), 0.07 (0.01, 0.36) P for trend < 0.0001 adjusting for age, primigravidae status and monthly income. Conclusion: higher DII was inversely associated with the odds of IDA among pregnant women. Behavioural change communication promoting the consumption of iron-rich foods might be a viable dietary strategy to alleviate the high burden of IDA among women in this population.

RESUMO

Introduction: poor maternal health outcomes remain a major public health issue in Nigeria. These have been shown to be affected by the low level of utilization of maternal healthcare services. This study investigates the levels of gender relations (GR) among Nigerian women and how these influence their utilization of maternal healthcare services. The relations are conceptualized as feminine (FGR), masculine (MGR) and egalitarian. Methods: data on household decision-making, antenatal care (ANC) visits, health facility delivery, and associated sociodemographic variables, were extracted from the 2018 Nigeria Demographic and Health Survey for 29,992 parous women aged 15-49 for a cross-sectional study. Associations were investigated using Chi-Square and regression analyses. Results: women with FGR constituted 5.7% of the population at the national level, while subnational variations ranged from 1.8% in the North-East to 12.8% in the South-South regions. The prevalence rates of the recommended minimum ANC visits (RMANC) and health facility delivery were 42.1% and 30.0% at the national level and were lowest in the northern regions. At both the unadjusted and adjusted levels, FGR was not significantly associated with RMANC and health facility delivery at the national level and in all the regions except the South-West. MGR was however significantly associated with increased odds of RMANC (OR: 2.235, CI: 2.043-2.444) and health facility delivery (OR: 2.571, CI: 2.369-2.791) at national level. Significant subnational variations in the association between gender relations and the utilization of maternal healthcare services were also recorded. Conclusion: sub-national variations in GR and their varying impacts on the utilization of maternal healthcare services in Nigeria suggest that gender-related policies to improve maternal health outcomes should be location-specific, rather than general. As FGR did not affect maternal healthcare services utilization, educating men on the benefits of supporting their wives to scale-up utilization is recommended.

RESUMO

Vulvovaginal candidosis (VVC) is a symptomatic vaginal yeast infection, especially caused by Candida spp. Although VVC is common among reproductive-age women, prevalence studies notice the uprise of vaginal Candida colonization to 30% during pregnancy by culture, especially in the last trimester. Recent studies have considered it a severe problem due to the emerging evidence showing the association of VVC with a higher chance of pregnancy-related complexities (e.g., preterm labor, premature rupture of membranes, congenital cutaneous candidosis, and chorioamnionitis). In this review, we have reassessed and summarized the prevalence rate of VVC in expecting mothers and analyzed the association of several factors to the increased risk of VVC during pregnancy in different regions of the world. Altogether, these data collected from various studies showed the highest prevalence of VVC during pregnancy, mostly in Asian and African countries (90.38%, 62.2%, and 61.5% in Kenya, Nigeria, and Yemen, respectively). The prevalence rate of VVC during pregnancy was also found to differ with age, gestation period, parity, educational status, and socioeconomic level. Some pregnancy-related factors (e.g., weakened immunity; elevated level of sex hormones, glycogen deposition; low vaginal pH; decreased cell-mediated immunity) and several clinical and behavioral factors can be suggested as potential risk factors of candidosis during pregnancy.

RESUMO

Background: Spontaneous abortion is one of the prevalent adverse reproductive outcomes, which seriously threatens maternal health around the world. Objective: The current study is aimed to evaluate the association between maternal age and risk for spontaneous abortion among pregnant women in China. Methods: This was a case-control study based on the China Birth Cohort, we compared 338 cases ending in spontaneous abortion with 1,352 controls resulting in normal live births. The main exposure indicator and outcome indicator were maternal age and spontaneous abortion, respectively. We used both a generalized additive model and a two-piece-wise linear model to determine the association. We further performed stratified analyses to test the robustness of the association between maternal age and spontaneous abortion in different subgroups. Results: We observed a J-shaped relationship between maternal age and spontaneous abortion risk, after adjusting for multiple covariates. Further, we found that the optimal threshold age was 29.68 years old. The adjusted odds ratio (95% confidence interval) of spontaneous abortion per 1 year increase in maternal age were 0.97 (0.90-1.06) on the left side of the turning point and 1.25 (1.28-1.31) on the right side. Additionally, none of the covariates studied modified the association between maternal age and spontaneous abortion (P > 0.05). Conclusions: Advanced maternal age (>30 years old) was significantly associated with increased prevalence of spontaneous abortion, supporting a J-shaped association between maternal age and spontaneous abortion.

RESUMO

Background: Pregnant women are a critical part of the community to assess various determinants of their future breastfeeding practice. This study aimed to assess the levels and determinants of breastfeeding knowledge, attitude, and intention among pregnant women. Methods: A hospital-based cross-sectional study was conducted among 422 pregnant women from January 18 to February 27, 2022, at Debre Tabor Comprehensive Specialized Hospital (DTCSH) in Northwest Ethiopia. Data were collected via face-to-face interviews from participants selected by convenience sampling technique. Data analysis was made using Stata version 16.0. Multiple logistic regression analysis was used to assess the determinants of the knowledge, attitude, and intention of pregnant women, with a p-value < 0.05 considered statistically significant. Result: About 57.8% of participants had adequate breastfeeding knowledge and only 46.9% had a positive attitude. Almost two-thirds (65.4%) of them had good intentions to breastfeed. Pregnant women attaining secondary education (AOR = 2.0; 95% CI: 1.31, 3.19), achieving college or university education (AOR = 3.13; 95% CI: 1.63, 7.41), being multiparous (AOR = 2.11; 95% CI: 1.33, 3.43), having four or more ANC visits (AOR:1.45; 95% CI: 1.21, 4.31), and having prior breastfeeding experience (AOR: 3.53; 95% CI: 2.22, 5.65) were significant predictors of adequate knowledge. Attending college or university education (AOR = 2.71;95% CI: 2.33, 5.13), being multiparous (AOR = 1.56; 95% CI: 1.32, 8.25), and having adequate knowledge (AOR = 2.02; 95% CI: 1.88,7.14) were determinants of a positive breastfeeding attitude. Whereas, advanced age (AOR = 1.44; 95% CI: 1.12, 5.59), adequate knowledge (AOR: 5.21; 95% CI: 1.51,8.04), and positive attitude (AOR = 2.41;95% CI:1.50, 4.27) were independent predictors of good breastfeeding intention. Conclusion: The breastfeeding knowledge and attitude of pregnant women were generally suboptimal. Their overall breastfeeding intention was also unsatisfactory. This highlights the need to develop culture-specific interventions aimed at improving breastfeeding knowledge, attitudes, and intention to enhance the appropriate breastfeeding practice of their future children.
