Pregnancy Outcomes among Women with Intermittent Asthma: A Retrospective Cohort Study

Background: It is already known that asthma strongly increases risks of poor pregnancy outcomes. We wonder whether intermittent asthma, the least severe form but accounting for the majority of cases, increases such adverse outcomes or not. Therefore, we conducted this study to compare adverse pregnancy outcomes between pregnancies with intermittent asthma and low-risk pregnancies (controls). Methods: The full medical records of pregnancies with intermittent asthma were comprehensively reviewed and low-risk pregnancies were randomly recruited as controls with a ratio of 10:1. The obstetric outcomes were compared between both groups, and the outcomes in the active subgroup of intermittent asthma (defined as at least one asthmatic attack during pregnancy) were also compared with the controls. Results: Of 364 study cases and 3640 controls, the rates of poor outcomes (preterm birth, preeclampsia, fetal growth restriction etc.) were not significantly different. However, cases with active disease slightly, but significantly, increased the risk of low birth weight. Moreover, mean gestational age was significantly lower in the study group. Conclusions: A new insight gained from this study is that intermittent asthma is not associated with poor pregnancy outcomes, but cases with asthmatic attack during pregnancy tended to increase the risk of preterm birth and low birth weight. This information is important for counseling and the planning of antepartum management.

Adverse Pregnancy

Objective: The primary objectives of this study are to compare the rates of preterm birth; fetal growth restriction and low birth weight between the following groups: (1) pregnant women treated for thyrotoxicosis and low-risk pregnancies; (2) between pregnant women with thyrotoxicosis with no need of medication and low-risk pregnancies; and (3) between those treated with MMI and PTU. Methods: The medical records of singleton pregnancies with thyrotoxicosis were comprehensively reviewed. Low-risk pregnancies matched for age and parity were randomly recruited as controls. The obstetric outcomes were compared between both groups; the outcomes of various subgroups of the thyrotoxicosis group were also compared. Results: A total of 408 pregnant women with thyrotoxicosis were recruited. Compared with the controls; the women of the thyrotoxicosis group had significantly higher rates of low birth weight (LBW) (23.7% vs. 17.7%; p: 0.036), preterm birth (19.3% vs. 12.3%; p: 0.007), preeclampsia (8.5% vs. 4.4%; p: 0.019) and cesarean section (21.5% vs. 16.0%; p: 0.046). In the thyrotoxicosis group; 67; 127; and 158 patients were treated with MMI; PTU and no anti-thyroid drug (ATD), respectively. All obstetric outcomes were comparable between the women treated with PTU and those with MMI; and between the controlled and uncontrolled groups. However, women who needed ATD had significantly higher rates of LBW and preterm birth than those without medications. Conclusions: Thyrotoxicosis, whether treated or not needing ATDs, was significantly associated with an increased risk of adverse pregnancy outcomes. Also, active disease, indicated by the need for ATD significantly increased the risk of such adverse outcomes; whereas the patients treated with MMI or PTU had comparable adverse outcomes.

Adverse Pregnancy

Background and Aim: Advanced maternal age pregnancy could be referred to as pregnancy after 35 years or older. The prevalence of postponing pregnancies is increasing day by day worldwide. However, limited evidence was found on advanced maternal age pregnancy association with fetal adverse outcomes. The present study aimed to evaluate the frequency of advanced maternal age selected fetal adverse pregnancy outcomes. Place and Duration: Obstetrics & Gynaecology department of Alkhidmat Hospital Kohat and Qazi Hussain Ahmad Medical Complex, Nowshera for duration of six months from November 2020 to April 2021. Materials and Methods: This single-centered retrospective study was conducted on 220 postpartum women in the study group (≥35 years) and 170 control group postpartum women (20-34 years) who delivered at Obstetrics & Gynaecology department of Alkhidmat Hospital Kohat and Qazi Hussain Ahmad Medical Complex, Nowshera after 28 gestational weeks. Individuals who met the inclusion criteria were enrolled and sampled based on randomized control sampling technique for both control and study groups. Data extraction checklist and pretested questionnaire were used for data collection from the maternal charts. Adverse pregnancy outcome and advanced maternal age was correlated adjusted relative risks and strength with a 95% confidence interval. SPSS version 20 was used for data analysis and considered p-value >0.05 as a statistical standard. Results: The adverse neonatal outcomes include low birth weight, preterm birth, and stillbirth with a prevalence 38 (17.4%), 46 (20.8%), and 31 (14.2%) respectively in the study group. In the control group, the incidence of low birth weight, preterm birth, and stillbirth was 21 (12.6%), 15 (14.6%) and 6 (3.5%) respectively. The stillbirth (ARR=3.16 95% CI (1.29–6.03) and preterm deliveries (ARR=2.71 95% CI (1.79–3.86) risk had significantly higher prevalence compared to control group advanced age pregnancy. Insignificance association was found between low birth weight and advanced maternal age. Conclusion: Stillbirth and preterm birth was the adverse fetal outcome significantly related with advanced maternal age pregnancy. There was no significant association between low birth weight and advanced maternal age. Keywords: Maternal age, Fetal Adverse Pregnancy Outcomes

Chlamydial trachomatis infection has been associated with adverse pregnancy and neonatal outcomes such as premature rupture of membranes, preterm birth, low birth weight, conjunctivitis, and pneumonia in infants. This review evaluates existing literature to determine potential benefits of antenatal screening and treatment of C. trachomatis in preventing adverse outcomes. A literature search revealed 1824 studies with 156 full-text articles reviewed. Fifteen studies were selected after fulfilling inclusion criteria. Eight studies focused on chlamydial screening and treatment to prevent adverse pregnancy outcomes such as premature rupture of membranes, preterm birth, low birth weight, growth restriction leading to small for gestational age infants, and neonatal death. Seven studies focused on the effects of chlamydial screening and treatment on adverse infant outcomes such as chlamydial infection including positive mucosal cultures, pneumonia, and conjunctivitis. Given the heterogeneity of those studies, this focused review was exclusively qualitative in nature. When viewed collectively, 13 of 15 studies provided some degree of support that antenatal chlamydial screening and treatment interventions may lead to decreased adverse pregnancy and infant outcomes. However, notable limitations of these individual studies also highlight the need for further, updated research in this area, particularly from low and middle-income settings.

Abstract Background Several risk factors predisposing women and their live-borns to adverse outcomes during pregnancy have been documented. Little is known about sanitation being a factor contributing to adverse pregnancy outcomes in India. The role of sanitation in adverse pregnancy outcomes remains largely unexplored in the Indian context. This study is an attempt to bring the focus on sanitation as a factor in adverse pregnancy outcome. Along with the sanitation factors, few confounder variables have also been studied in order to understand the adverse pregnancy outcomes. Methods The study is based on the fourth round of National Family Health Survey (NFHS-IV) covering 26,972 married women in the age-group 15–49. The study variables include the mother’s age, Body Mass Index (BMI), education, anemia, and Antenatal care (ANC) visits during their last pregnancy. The household level variable includes place of residence, religion, caste, wealth index, access to toilet, type of toilet, availability of water within toilet premises, and facility of hand wash near the toilet. Children study variables include Low Birth Weight (LBW), the order of birth (Parity), and the death of the children of the women in the last 5 years. The target variable Adverse Pregnancy Outcome (APO) was constructed using children born with low birth weight or died during the last pregnancy. Results We calculated both adjusted as well as unadjusted odds ratios for a better understanding of the association between sanitation and adverse pregnancy outcomes. Findings from the study showed that women who did not have access to a toilet within the house had a higher risk of adverse pregnancy outcome. In the multivariable model, no association was observed for adverse pregnancy outcome among women who did not have access to toilet and women who used shared toilet. Teenage (15–19 years), uneducated, underweight and anemic mothers were more likely to face APO as compare to other mothers in similar characteristics group. Conclusions Our findings contribute to the decidedly less available literature on maternal sanitation behaviour and adverse pregnancy outcomes. Our results support that sanitation is a very significant aspect for women who are about to deliver a baby as there was an association between sanitation and adverse pregnancy outcome. Education on sanitation practices is the need of the hour as much as it needs to follow.

Adverse Pregnancy

Introduction. Pregnancy at an advanced maternal age is defined as pregnancy at 35 years or older. Today, women postpone pregnancy due to different socioeconomic and personal reasons. However, there was limited evidence on fetal adverse outcomes’ association with pregnancy at an advanced maternal age in Ethiopia and particularly in the study area. This study was aimed at assessing the effect of pregnancy at an advanced age on selected neonatal adverse pregnancy outcomes in Debre Markos Referral Hospital, Ethiopia, 2019. Methods. Institution-based retrospective cohort study was conducted on 303 exposed (35 years and older) and 604 nonexposed (20–34 years old) immediate postpartum women who delivered at Debre Markos Referral Hospital after 28 weeks of gestation. All exposed women who fulfilled the inclusion criteria were sampled, and systematic random sampling was employed for those in the nonexposed group. The data were collected from 1st of July to 30th of December, 2019, by face-to-face interview and extraction from maternal chart using a structured questionnaire and data extraction checklist, respectively. Binary logistic regression (bivariate and multivariable) model was fitted, and wealth index was analyzed by principal component analysis. Adjusted relative risk with respect to 95% confidence interval was employed for the strength and directions of association between advanced maternal age and selected adverse pregnancy outcomes, respectively. P -value of <0.05 was used to declare statistical significance. Results. The incidence of adverse neonatal outcomes including stillbirth, preterm birth, and low birth weight in the advanced maternal age group was 13.2%, 19.8%, and 16.5%, respectively. The incidence of stillbirth, preterm birth, and low birth weight in the nonexposed group was 3.1%, 8.4%, and 12.4%, respectively. The advanced maternal age group had three times the risk of stillbirth compared with the nonexposed group (ARR = 3.14 95% CI (1.30–7.00)). The advanced maternal age group had 2.66 times the risk of delivering preterm fetus (ARR = 2.66 95% CI (1.81–3.77)) compared with the younger counterparts. Low birth weight was not significantly associated with pregnancy at an advanced maternal age. Conclusion. Fetal adverse outcomes including stillbirth and preterm birth were significantly associated with pregnancy at an advanced maternal age.

Objective This study aimed to analyze the effects of maternal weight on adverse pregnancy outcomes. Methods Data were retrospectively collected from a hospital in Wuhan, China. A total of 1593 pregnant women with singletons were included. Adverse outcomes during pregnancy, such as small for gestational age (SGA), large for gestational age (LGA), and hypertensive disorders in pregnancy (HDP) were analyzed. Results The risks of low birth weight, SGA, and preterm birth were significantly higher in the inadequate gestational weight gain (GWG) group compared with the adequate GWG group. GWG over the guidelines was related to a higher risk of macrosomia, LGA, cesarean section, and HDP than GWG within the guidelines. The risks of low birth weight (OR = 5.082), SGA (OR = 3.959), preterm birth (OR = 3.422), and gestational diabetes mellitus (OR = 1.784) were significantly higher in women with a normal pre-pregnancy body mass index (BMI) and inadequate GWG compared with women with a normal pre-pregnancy BMI and adequate GWG. The risks of macrosomia (OR = 3.654) and HDP (OR = 1.992) were increased in women with normal pre-pregnancy BMI and excessive GWG. Conclusion Women with an abnormal BMI and inappropriate GWG have an increased risk of adverse maternal and infant outcomes. Weight management during the perinatal period is required.

Abstract Background The study aimed to determine the association between antenatal visits and adverse pregnancy outcomes among Ghanaian women in the North East Region.Methods We analysed data on the birth records of 2907 women who delivered at Baptist Medical Centre between January 2018 to December 2018. Binary logistic regression was used to assess the association between antenatal visits and four adverse pregnancy outcomes – preterm birth, low birth weight, small-for-gestational-age, and stillbirth. Results Our analysis showed that ANC attendance offered some protection against preterm birth, low birth weight, small-for-gestational-age, and stillbirth in the study sample, albeit with variations in the protective effect depending on the number of visits attended. An increase in the number of ANC visits was associated with a decrease in the occurrence of the adverse pregnancy outcomes, except for low birth weight where the protective effect was observed only after four ANC visits. Adolescent mothers attended the least number of ANC visits during the study period. Our analysis suggests that the effect of ANC attendance on preterm birth and low birth weight differed depending on the age of the mother. Among mothers who never attended any ANC visits, adolescent mothers and older mothers had higher odds of low birth weight compared to mothers aged 20-30years. Surprisingly, the odds of preterm birth among the mothers who never attended any ANC visits was lower in adolescent mothers and older mothers compared to mothers aged 20-30years. For mothers who attended four or more ANC visits, the odds of low birth weight were higher in adolescent mothers and lower in older mothers compared to mothers aged 20-30years. However, the odds of preterm birth among the mothers who attended more than four ANC visits was higher in adolescent mothers and older mothers compared to mothers aged 20-30years. Conclusion The findings highlight the importance of ANC in preventing adverse pregnancy outcomes and the need for every pregnant woman to initiate and ensure adequate ANC contacts. The results also highlight the need to prioritise adolescents and older pregnant women for ANC.

Adverse Pregnancy

Abstract: Data from epidemiological and clinical studies published in the past two decades indicate certain association between periodontal disease and increased risk for preterm birth or low birth weight. Although the strength of those observed associations is weak, periodontitis today is considered as one of the potentially modifiable risk factors for adverse pregnancy outcomes. The aims of the publication are to summarize the epidemiological and clinical evidence for the impact of periodontal disease on adverse pregnancy outcomes and to make an attempt to overview the potential biological mechanism behind this association. The majority of epidemiological and clinical studies found certain negative effect of poor maternal periodontal condition on the incidence of low birth weight, preterm birth, pre-eclampsy, restricted foetal growth or even stillbirth. Two possible biological pathways have so far been identified: 1) the direct dissemination of the periodontal pathogens or their toxic by-products which reach the foetal-placental unit, and 2) an indirect mechanism when the circulating systemic inflammatory mediators induced by the periodontal inflammation can provoke secondary inflammation and foetal damage in the amnion. The periodontal therapy applied during the second or third trimesters has not been proven to reduce the incidence of any adverse pregnancy outcomes in pregnant women. A much more prophylaxis-oriented approach in periodontal treatment is needed. The adequate periodontal therapy should be completed before the conception to provide benefit to the pregnant women and also the new born baby. Orv Hetil. 2018; 159(25): 999–1007.
