Factors associated with pregnant women's willingness to receive maternal pertussis vaccination in Guizhou Province, China: An exploratory cross-sectional study

The rise in pertussis incidence among infants in Guizhou, China underscores the need for maternal acellular pertussis vaccine (aP) immunization, a key strategy in protecting infants from severe health consequences. However, the willingness of pregnant women in Guizhou to receive this vaccine is not well-understood. This study aimed to explore pregnant women's intentions toward maternal pertussis vaccination in Guizhou and identify the associated factors. A questionnaire based on the health belief model, was administered in an exploratory cross-sectional study from January to February 2022. Data from 564 participants were collected and analyzed. The chi-square test, Mann-Whitney U test, and Poisson regression were used to identify potential factors associated with vaccination intentions. Participants' median age was 27 y (interquartile range (IQR): 24-31), and the median number of children per participant was one. The study found that only 36.0% of the participants intended to receive the aP vaccine while 64.0% were uncertain or negative in this regard. Significant factors associated with intentions to vaccinate included perceived barriers and cues for action and perceived benefits. The major barriers for low vaccination intentions were safety concerns for both the fetus and the mother, and family members' negative attitudes. Free vaccines, perceiving preventive benefits, observing other pregnant women getting vaccinated, and healthcare provider recommendations may facilitate vaccination intentions. Multiple immune strategies should be developed or optimized to cope with the resurgence of pertussis.

Secondhand smoke prevention through the perceptions of pregnant women with smoking family members: a Thailand study

PURPOSE

Pregnant women with smoking family members are at risk of exposure to second-hand smoke, which leads to adverse pregnancy outcomes. Second-hand smoke prevention is thus important but remains less understood based on pregnant women's perceptions. This study aimed to describe the perceptions of pregnant women on second-hand smoke prevention.

METHODS

This study employed a qualitative descriptive approach. Data collection was performed between July and August 2023 through in-depth interviews with 17 pregnant women purposively selected from a province in central Thailand. The verbatim transcribed data were analysed using thematic analysis.

RESULTS

Five themes emerged: unclear understanding of second-hand smoke; influences shaping perceptions related to second-hand smoke; attempt to prevent second-hand smoke exposure; barriers to prevention of second-hand smoke exposure; and needs related to prevention of second-hand smoke exposure.

CONCLUSION

The findings provide insights into second-hand smoke prevention from the perception of pregnant women with smoking family members. Healthcare professionals need to design interventions tailored to pregnant women's needs and involve smoking family members. It is necessary to develop and incorporate clinical guidelines into standard prenatal care to support healthcare personnel in identifying, assessing, educating, and mitigating the issue of second-hand smoking exposure.

Deep metagenomic characterization of the gut virome in pregnant women with preeclampsia

Preeclampsia (PE), a pregnancy-specific syndrome, has been associated with the gut bacteriome. Here, to investigate the impact of the gut virome on the development of PE, we identified over 8,000 nonredundant viruses from the fecal metagenomes of 40 early-onset PE and 37 healthy pregnant women and profiled their abundances. Comparison and correlation analysis showed that PE-enriched viruses frequently connected to Blautia species enriched in PE. By contrast, bacteria linked to PE-depleted viruses were often the Bacteroidaceae members such as Bacteroides spp., Phocaeicola spp., Parabacteroides spp., and Alistipes shahii. In terms of viral function, PE-depleted viruses had auxiliary metabolic genes that participated in the metabolism of simple and complex polysaccharides, sulfur metabolism, lipopolysaccharide biosynthesis, and peptidoglycan biosynthesis, while PE-enriched viruses had a gene encoding cyclic pyranopterin monophosphate synthase, which seemed to be special, that participates in the biosynthesis of the molybdenum cofactor. Furthermore, the classification model based on gut viral signatures was developed to discriminate PE patients from healthy controls and showed an area under the receiver operating characteristic curve of 0.922 that was better than that of the bacterium-based model. This study opens up new avenues for further research, providing valuable insights into the PE gut virome and offering potential directions for future mechanistic and therapeutic investigations, with the ultimate goal of improving the diagnosis and management of PE.IMPORTANCEThe importance of this study lies in its exploration of the previously overlooked but potentially critical role of the gut virome in preeclampsia (PE). While the association between PE and the gut bacteriome has been recognized, this research takes a pioneering step into understanding how the gut virome, represented by over 8,000 nonredundant viruses, contributes to this condition. The findings reveal intriguing connections between PE-enriched viruses and specific gut bacteria, such as the prevalence of Blautia species in individuals with PE, contrasting with bacteria linked to PE-depleted viruses, including members of the Bacteroidaceae family. These viral interactions and associations provide a deeper understanding of the complex dynamics at play in PE.

Consumption of ultra-processed foods and mental health of pregnant women from the South of Brazil

The objective of this study is to evaluate the association between the consumption of ultra-processed foods (UPF) and the mental health of pregnant women from the South of Brazil. This is a cross-sectional study carried out in Criciúma, Brazil, through face-to-face interviews, from April to December 2022. Pregnant women aged 18 or older who underwent prenatal care in the 48 Basic Health Units of the municipality and who were in their third trimester of pregnancy were included. High consumption of UPF was considered as 6 or more items or subgroups of UPF consumed on the day before the interview, using the Nova-UPF screener. The mental health variables were depressive symptoms, stress, sadness, and anxiety. Crude and adjusted analyses were conducted using the Fisher's exact test and the Poisson regression with robust variance. In total, 428 pregnant women were studied; most of them were aged between 20 and 25 years and were white. Pregnant women who presented high consumption of UPF were 1.42-fold (95%CI 1.06;1.92) more likely to experience anxiety and presented a prevalence 56% (95%CI 1.18;2.07) higher of stress when compared to those who did not present high consumption of UPF. The prevalence of depressive symptoms and feelings of sadness was 1.31-fold (95%CI 1.08;1.60) and 3.41-fold (95%CI 1.77;6.58) higher among those with high consumption of UPF, respectively. The results suggest that diet quality is associated with the mental health of pregnant women. Promoting joint actions focused on food and nutritional education for pregnant women, as well as mental health, is necessary.

Stimulating Preconception Care Uptake by Women With a Vulnerable Health Status Through a Mobile Health App (Pregnant Faster): Pilot Feasibility Study

BACKGROUND

A low socioeconomic status is associated with a vulnerable health status (VHS) through the accumulation of health-related risk factors, such as poor lifestyle behaviors (eg, inadequate nutrition, chronic stress, and impaired health literacy). For pregnant women, a VHS translates into a high incidence of adverse pregnancy outcomes and therefore pregnancy-related inequity. We hypothesize that stimulating adequate pregnancy preparation, targeting lifestyle behaviors and preconception care (PCC) uptake, can reduce these inequities and improve the pregnancy outcomes of women with a VHS. A nudge is a behavioral intervention aimed at making healthy choices easier and more attractive and may therefore be a feasible way to stimulate engagement in pregnancy preparation and PCC uptake, especially in women with a VHS. To support adequate pregnancy preparation, we designed a mobile health (mHealth) app, Pregnant Faster, that fits the preferences of women with a VHS and uses nudging to encourage PCC consultation visits and engagement in education on healthy lifestyle behaviors.

OBJECTIVE

This study aimed to test the feasibility of Pregnant Faster by determining usability and user satisfaction, the number of visited PCC consultations, and the course of practical study conduction.

METHODS

Women aged 18-45 years, with low-to-intermediate educational attainment, who were trying to become pregnant within 12 months were included in this open cohort. Recruitment took place through social media, health care professionals, and distribution of flyers and posters from September 2021 until June 2022. Participants used Pregnant Faster daily for 4 weeks, earning coins by reading blogs on pregnancy preparation, filling out a daily questionnaire on healthy lifestyle choices, and registering for a PCC consultation with a midwife. Earned coins could be spent on rewards, such as fruit, mascara, and baby products. Evaluation took place through the mHealth App Usability Questionnaire (MAUQ), an additional interview or questionnaire, and assessment of overall study conduction.

RESULTS

Due to limited inclusions, the inclusion criterion "living in a deprived neighborhood" was dropped. This resulted in the inclusion of 47 women, of whom 39 (83%) completed the intervention. In total, 16 (41%) of 39 participants visited a PCC consultation, with their main motivation being obtaining personalized information. The majority of participants agreed with 16 (88.9%) of 18 statements of the MAUQ, indicating high user satisfaction. The mean rating was 7.7 (SD 1.0) out of 10. Points of improvement included recruitment of the target group, simplification of the log-in system, and automation of manual tasks.

CONCLUSIONS

Nudging women through Pregnant Faster to stimulate pregnancy preparation and PCC uptake has proven feasible, but the inclusion criteria must be revised. A substantial number of PCC consultations were conducted, and this study will therefore be continued with an open cohort of 400 women, aiming to establish the (cost-)effectiveness of an updated version, named Pregnant Faster 2.

Effects of an individualized nutritional educational program in pregnant women: A randomized controlled trial in Japan

AIM

To evaluate the effectiveness of an individualized nutritional education program in promoting adequate nutrient intake in pregnant women.

METHODS

A stratified randomized controlled trial was conducted. Participants were stratified by factors affecting the primary outcome and randomly assigned to the intervention or control groups. Intervention group participants received an individualized 30-min booklet-based education program in their 2nd and 3rd trimesters; the control group received usual care. The primary outcome was protein intake after the intervention, which was compared between the intervention and control groups. Secondary outcomes included comparing the amount of increase of protein before and after the intervention. Nutrient intake was measured using a self-administered short dietary history questionnaire, and analyses of covariance and t tests were performed.

RESULTS

Of the 130 participants, 66 were assigned to the intervention group and 64 to the control group. There was no difference in protein intake between the two groups after the intervention (p = .051, 95% CI [-0.021, 12.4]). Comparing the increase in protein intake before and after intervention, the intervention group was 7.4 g/day higher than that of the control group (p = .040; F = 4.31; effect size = 0.36).

CONCLUSIONS

The primary outcome, a comparison of protein intake between the groups after the program, revealed no significant differences. However, on comparing the amount of protein increase before and after the intervention, the intervention group's increase was significantly higher than that of the control group. Results indicate the potential for individualized face-to-face interventions for pregnant women in Japan.

Preeclampsia Onset, Days to Delivery, and Autism Spectrum Disorders in Offspring: Clinical Birth Cohort Study

BACKGROUND

Maternal preeclampsia is associated with a risk of autism spectrum disorders (ASD) in offspring. However, it is unknown whether the increased ASD risk associated with preeclampsia is due to preeclampsia onset or clinical management of preeclampsia after onset, as clinical expectant management of preeclampsia allows pregnant women with this complication to remain pregnant for potentially weeks depending on the onset and severity. Identifying the risk associated with preeclampsia onset and exposure provides evidence to support the care of high-risk pregnancies and reduce adverse effects on offspring.

OBJECTIVE

This study aimed to fill the knowledge gap by assessing the ASD risk in children associated with the gestational age of preeclampsia onset and the number of days from preeclampsia onset to delivery.

METHODS

This retrospective population-based clinical cohort study included 364,588 mother-child pairs of singleton births between 2001 and 2014 in a large integrated health care system in Southern California. Maternal social demographic and pregnancy health data, as well as ASD diagnosis in children by the age of 5 years, were extracted from electronic medical records. Cox regression models were used to assess hazard ratios (HRs) of ASD risk in children associated with gestational age of the first occurrence of preeclampsia and the number of days from first occurrence to delivery.

RESULTS

Preeclampsia occurred in 16,205 (4.4%) out of 364,588 pregnancies; among the 16,205 pregnancies, 2727 (16.8%) first occurred at <34 weeks gestation, 4466 (27.6%) first occurred between 34 and 37 weeks, and 9012 (55.6%) first occurred at ≥37 weeks. Median days from preeclampsia onset to delivery were 4 (IQR 2,16) days, 1 (IQR 1,3) day, and 1 (IQR 0,1) day for those first occurring at <34, 34-37, and ≥37 weeks, respectively. Early preeclampsia onset was associated with greater ASD risk (P=.003); HRs were 1.62 (95% CI 1.33-1.98), 1.43 (95% CI 1.20-1.69), and 1.23 (95% CI 1.08-1.41), respectively, for onset at <34, 34-37, and ≥37 weeks, relative to the unexposed group. Within the preeclampsia group, the number of days from preeclampsia onset to delivery was not associated with ASD risk in children; the HR was 0.995 (95% CI 0.986-1.004) after adjusting for gestational age of preeclampsia onset.

CONCLUSIONS

Preeclampsia during pregnancy was associated with ASD risk in children, and the risk was greater with earlier onset. However, the number of days from first preeclampsia onset to delivery was not associated with ASD risk in children. Our study suggests that ASD risk in children associated with preeclampsia is not increased by expectant management of preeclampsia in standard clinical practice. Our results emphasize the need to identify effective approaches to preventing the onset of preeclampsia, especially during early pregnancy. Further research is needed to confirm if this finding applies across different populations and clinical settings.

Psychometric Properties of the Healthy Lifestyle Behaviors Scale in Portuguese Pregnant Women

BACKGROUND

Pregnancy provides a privileged and opportune moment to implement interventions promoting healthy lifestyle behaviors and significantly improving perinatal outcomes. The Healthy Lifestyle Behaviors Scale (HLBES) can be used to assess health promoting behaviors, such as diet, physical activity, and mental health.

PURPOSE

This study aimed to examine the psychometric properties of the HLBES in Portuguese pregnant women.

METHODS

A methodological study was conducted on a convenience sample of 192 pregnant women receiving prenatal care. After cross-cultural adaptation, an exploratory factor analysis and internal consistency assessment were carried out to evaluate the psychometric properties of the scale. Data collected included the Healthy Lifestyle Beliefs Scale to assess the HLBES' criterion validity.

RESULTS

Exploratory factor analysis with Varimax rotation yielded 2 subscales that explained 45.23% of the total variance. The scale revealed an overall internal consistency of 0.78 and a good criterion validity with the Healthy Lifestyle Beliefs Scale (r = 0.65, P < .01).

CONCLUSION

Our results suggest that the HLBES is an instrument for reporting healthy lifestyle behaviors in Portuguese pregnant women; however, further studies are recommended. This scale can be used to not only describe healthy lifestyle behaviors in pregnant women but also to determine the effects of health promoting interventions.

Clinical Outcome and Factors with Dietary Behaviors in Pregnant Women with Listeria monocytogenes: A Hospital-Based Case-Control Study in Shanghai

Listeriosis is a globally rare foodborne disease that causes fetal-placental infection, leading to adverse pregnancy outcome, while limited research among pregnant women is available in China. This study was therefore aimed at analyzing the incidence, clinical manifestations, and clinical outcome of listeriosis among pregnant women and its associated dietary behavior risk factors in prevention. A hospital-based case-control study had been conducted from January 2017 to December 2021. Clinical data, laboratory information, and questionnaires including dietary behaviors and personal hygiene were collected within 2 days after case diagnosis. There were 48 pregnant women, including 12 cases and 36 controls, with an average age of 31.19 ± 3.75 years. The incidence of admission-based listeriosis among pregnant women was 1.6058 per 10,000. The 12 strains were divided into 3 serotypes: 1/2a(83.33%), 1/2b(8.33%), and 4b(8.33%). Among the cases, 5 cases (41.67%) resulted in abortion, 3 cases (25%) induced preterm labor, and 4 cases (33.33%) had full-term deliveries after treatment. There were 7 live births in the case group, among which 6 were admitted to the neonatal intensive care unit (NICU), while 1 case had a healthy fetal outcome. All patients in the control group gave birth to live fetuses. Epidemiological investigation revealed that pregnant women dining at restaurants three or more times per week might increase the risk of having Listeria infection. There were no significant differences in dietary consumed behaviors, hand hygiene, and refrigerator usage behaviors between case and control groups. The study suggested that dining at restaurants might be associated with Listeria infection among pregnant women. Therefore, it is essential to enhance education on listeriosis serious consequences and promote healthy dietary and hygiene habits among pregnant women.

The influencing factors of changes in physical activity levels of pregnant women during pregnancy: From the perspective of continuous care

A comprehensive understanding of physical activity levels (PAL) among Chinese pregnant women and an exploration, from a continuous care perspective, of various factors influencing these activity levels. Investigating the correlations between adverse habits, psychological factors, and PAL in prenatal health management. This study aims to provide substantial guidance for prenatal health management and personalized care, offering recommendations to healthcare professionals and policymakers to enhance the overall health and well-being of pregnant women. This study enrolled 1256 pregnant women as research subjects. Baseline information was collected through a personal information collection form. Subsequently, continuous care was provided during the early, middle, and late stages of pregnancy, documenting the respective influencing factors. Simultaneously, the International Physical Activity Questionnaire (IPAQ) was utilized to assess the PAL of pregnant women across different trimesters. Finally, using the SPSS software version 25.0, a combined approach of generalized linear mixed effects (GLME) models and multivariate logistic regression was used to statistically analyze the collected data, comprehensively exploring the influencing factors of PAL during pregnancy. The proportion of research subjects engaged in low-level physical activity decreased from 60.80% to 40.34% across various stages of pregnancy, while the proportion engaged in moderate-level physical activity ranged from 25.32% to 40.75%. Meanwhile, the proportion engaged in high-level physical activity accounted for 13.88% to 18.91%.There was P = .021 and β = -0.276 for smoking before pregnancy. The P-value of pregnant women who smoke in the second trimester was.035, the Odds Ratio (OR) value was 0.638, and the 95% confidence interval (CI) was (0.406, 0.972). The difference was statistically significant (all P < .05). In China, the physical activity level of pregnant women is generally low, which is related to factors such as smoking, alcohol consumption, sleep disorders, and depression during pregnancy. Medical personnel should improve the living habits of pregnant women and enhance their PAL through measures such as health education and psychological counseling.

Experiences of women with gestational diabetes about fear of having diabetes in their babies: A qualitative study

Gestational Diabetes Mellitus is an important public health problem that often occurs during pregnancy. This study aimed to reveal the experiences of women with gestational diabetes regarding the fear of having diabetes in their babies. A qualitative research method was carried out with a phenomenological approach. The interviews had a semi-structured form and were recorded on an online/face-to-face voice recorder, and thematic content analysis was performed on the MAXQDA22. Following the inclusion criteria, 12 women with gestational diabetes from the 2 hospitals in the study were included, and in this way, the study reached saturation. As a result of the interviews, 4 main themes and one subtheme were obtained from coding. The main themes were "sugar baby," "risky child," "raising a fearful baby," and "problematic gene carrier." From the main theme of "problematic gene carrier," the subtheme of "pregnancies with problematic genes" was created. This research sheds light on the problems women with gestational diabetes experience with themselves and their babies, and how they deal with these problems. Women with gestational diabetes try to accept and cope with the diagnosis. This research shows that the women were worried about both themselves and their babies. Illuminating the experiences of women with gestational diabetes is part of an integrative care approach that will help increase quality care and treatment in endocrine clinics. More qualitative studies are needed to learn more about the experiences of women with gestational diabetes in endocrine clinics.

Choline in pregnant women: a systematic review and meta-analysis

CONTEXT

Choline is a critical nutrient. Inadequate choline intake during pregnancy increases the risk of adverse maternal and offspring health.

OBJECTIVE

A systematic review and meta-analysis were conducted to examine the current recommendations for choline intake by pregnant women, estimate the overall prevalence of pregnant women with adequate choline intake, and explore associations between maternal choline level and adverse pregnancy outcomes (APOs).

METHODS

Choline recommendations for pregnant women were assessed from eight nutrient guidelines of the United States, United Kingdom, Canada, Australia, Asia, International Federation of Gynecology and Obstetrics, and World Health Organization. Data on the prevalence of pregnant women with adequate choline intake and the association between maternal choline level and APOs were collected from 5 databases up to May 2023. Meta-analyses with random effects and subgroup analyses were performed for the pooled estimate of prevalence and association.

RESULTS

Five recent nutrition guidelines from the United States (United States Department of Agriculture), United States (Food and Drug Administration), Canada, Australia, and the International Federation of Gynecology and Obstetrics have emphasized the importance of adequate choline intake for pregnant women. Of 27 publications, 19 articles explored the prevalence and 8 articles explored the association. Meta-analysis of 12 prevalence studies revealed a concerning 11.24% (95% confidence interval, 6.34-17.26) prevalence of pregnant women with adequate choline intake recommendations. A meta-analysis of 6 studies indicated a significant association between high maternal choline levels and a reduced risk of developing APOs, with an odds ratio of 0.51 (95% confidence interval, 0.40-0.65).

CONCLUSION

The existing guidelines highlight the importance of choline in supporting maternal health and fetal development during pregnancy. Furthermore, a high maternal choline level was likely to be associated with a lower risk of APOs. However, 88.76% of pregnant women do not achieve the optimal choline intake. Therefore, specific policies and actions may be necessary to improve choline intake in pregnant women's care and support the well-being of pregnant women.

Possible Risk Factors and Their Potential Associations with Combined Heavy Metal Exposures in Pregnant Women in the Republic of Suriname

Background

The exposure of pregnant women to multiple environmental pollutants may be more disadvantageous to birth outcomes when compared to single-compound contaminations.

Objective

This study investigated the mixed exposures to mercury, manganese, or lead in 380 pregnant Surinamese women. The factors that might be associated with the heavy metal exposures and the relative risk of the potential factors to cause the mixed exposures were explored. The influencing factors of exposures to mixed contaminants assessed were living in Suriname's rural regions, several parts of which are contaminated with heavy metals emitted from artisanal and small-scale gold mining and agricultural activities; the consumption of potentially contaminated foods; advanced maternal age; as well as a relatively low formal educational level and monthly household income.

Methods

Descriptive statistics were used to calculate frequency distributions and χ2-contingency analyses to calculate associations and relative risks (RR) with 95% confidence intervals (CI).

Findings

Blood levels of two or three of the heavy metals above public health limits were observed in 36% of the women. These women were more often residing in the rural regions, primarily consumed potentially contaminated food items, were 35 years or older, were lower educated, and more often had a lower household income. However, only living in the rural regions (RR = 1.48; 95% CI 1.23-1.77) and a low household income (RR = 1.38; 95% CI 1.15-1.66) significantly increased the risk of exposure exceeding levels of concern to two or three of the heavy metals (by 48% and 38%, respectively).

Conclusion

More comprehensive pharmacological, ecological, and epidemiological studies about exposures to mixed heavy metal contaminations in pregnant women are warranted.

Intimate partner violence during pregnancy and quality of life in Southern Brazil: a cross-sectional study, 2022

OBJECTIVE

To analyze the association between intimate partner violence during pregnancy (IPVP) and quality of life (QOL).

METHODS

A cross-sectional study was conducted with pregnant women receiving care in Primary Health Care in the municipality of Criciúma, Santa Catarina state, Brazil, in 2022; QOL was assessed in the physical, psychological, social relationship and environmental domains using WHOQOL-Bref instrument; IPVP was evaluated by means of the World Health Organization Violence Against Women; Crude and adjusted linear regression analyses were performed.

RESULTS

A total of 389 pregnant women were evaluated; IPVP was observed in 13.6% of cases; in the adjusted analysis, IPVP remained associated with physical, psychological and social relationship domains; pregnant women who experienced IPVP had a reduction in their QOL score by 9.77, 11.07 and 8.95 points, respectively, when compared to those who did not experience IPVP.

CONCLUSION

IPVP was associated with poorer QOL in the physical, psychological and social relationships domains. Health services equipped to address and prevent violence against pregnant women are essential.

MAIN RESULTS

Intimate partner violence (IPV) was observed in 13.6% of pregnant women and was associated with poorer quality of life in the physical, psychological and social relationship domains.

IMPLICATIONS FOR SERVICES

The results emphasize the need for an intersectoral approach in addressing the issue, with specialized healthcare centers for situations of violence integrated with social assistance and public security.

PERSPECTIVES

Development of intersectoral policies and actions that strengthen existing ones and ensure social and healthcare assistance to pregnant women victims of violence and their children, given the negative impact of IPVP on quality of life.

Antibody response to malaria vaccine candidates in pregnant women with Plasmodium falciparum and Schistosoma haematobium infections

Malaria in pregnancy has severe consequences for the mother and foetus. Antibody response to specific malaria vaccine candidates (MVC) has been associated with a decreased risk of clinical malaria and its outcomes. We studied Plasmodium falciparum (Pf) and Schistosoma haematobium (Sh) infections and factors that could influence antibody responses to MVC in pregnant women. A total of 337 pregnant women receiving antenatal care (ANC) and 139 for delivery participated in this study. Pf infection was detected by qPCR and Sh infection using urine filtration method. Antibody levels against CSP, AMA-1, GLURP-R0, VAR2CSA and Pfs48/45 MVC were quantified by ELISA. Multivariable linear regression models identified factors associated with the modulation of antibody responses. The prevalence of Pf and Sh infections was 27% and 4% at ANC and 7% and 4% at delivery. Pf infection, residing in Adidome and multigravidae were positively associated with specific IgG response to CSP, AMA-1, GLURP-R0 and VAR2CSA. ITN use and IPTp were negatively associated with specific IgG response to GLURP-R0 and Pfs48/45. There was no association between Sh infection and antibody response to MVC at ANC or delivery. Pf infections in pregnant women were positively associated with antibody response to CSP, GLURP-R0 and AMA-1. Antibody response to GLURP-R0 and Pfs48/45 was low for IPTp and ITN users. This could indicate a lower exposure to Pf infection and low malaria prevalence observed at delivery.

The factor structure of "expectant mothers of concern" as perceived by midwives

AIM

To clarify the factor structure of "expectant mothers of concern" for whom midwives anticipate difficulties in future childrearing.

METHODS

The participants were 2633 midwives working at hospitals and clinics in Japan. Data were collected using a 108-item, five-point Likert scale questionnaire about the behaviors, appearance, and family relationships of the expectant mothers of concern to the nurses. Items with a mean equal to or greater than 4.0 were selected as items considered relevant to expectant mothers of concern by midwives. Exploratory factor analysis, confirmatory factor analysis, and further secondary factor analysis were conducted.

RESULTS

The factor structure of the expectant mothers of concern as perceived by midwives comprised seven factors, including 23 items: "Suspected of being a victim of intimate partner violence," "Uneasy feeling about the expectant mother's marital relationship," "Perception that the expectant mother is conflicted about her pregnancy," "Uneasy feeling about the expectant mother's actions/behaviors concerning her medical checkups," "Engages in physically risky actions and behaviors," "Does not appear to be able to build relationships with children," and "Makes remarks that indicate possible bonding disorder" (goodness-of-fit index = 0.910, adjusted goodness-of-fit index = 0.879, comparative fit index = 0.939, and root mean square error of approximation = 0.070). Further, a secondary factor, "Expectant mothers who must urgently be connected to support," was extracted.

CONCLUSIONS

The elucidation of the factor structure of the expectant mothers of concern could help midwives identify expectant mothers who may face difficulties in future childrearing.

Exploration of cardiopulmonary resuscitation teamwork training for maternal cardiac arrest using the SimMan intelligent simulation platform: A simulation teaching study

Background and Aims

Maternal cardiac arrest is the most urgent clinical event in obstetrics and can lead to serious consequences, such as maternal or fetal death. Therefore, the training of team cardiopulmonary resuscitation (CPR) skills for obstetricians is essential. The aim of this study was to investigate the effect of applying intelligent simulation to CPR in maternal cardiac arrest teamwork training for obstetricians.

Methods

Twenty-four obstetricians who participated in the "Maternal First Aid Workshop," organized by our hospital in 2018, were selected as training participants. The SimMan intelligent comprehensive patient simulator was used to train the CPR team collaboration with first-aid skills. Each team participating in the training was assessed before and after the training using a questionnaire survey.

Results

The evaluation of the results after the training showed that all four teams were qualified and that the timing of the cesarean section was 100% correct. The mean score, team collaboration score, and chest compression fraction were significantly higher than before training. Teamwork CPR assessment time, interruption time of chest compressions, and artificial airway establishment time were significantly shorter than before training. The questionnaire survey showed that 95.8% of the physicians reported that the training was rewarding and helpful to their clinical work, and 100% of the physicians believed that obstetricians require similar training.

Conclusion

Using the SimMan intelligent comprehensive patient simulator to train obstetricians for CPR of maternal cardiac arrest teamwork first-aid skills can significantly improve the training effect, clinical first-aid skills, and teamwork awareness.

Prevalence of self-medication practices among pregnant women in India: A systematic review and meta-analysis

BACKGROUND

Self-medication practice among pregnant women is a global concern. However, its understanding in the Indian context is limited due to a lack of comprehensive studies.

PURPOSE

This study aimed to comprehensively assess the prevalence of self-medication, the medications used for self-medication, diseases/conditions associated with self-medication, and the reasons for self-medication among Indian pregnant women.

METHODS

This study was carried out following the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A thorough search was done in PubMed, Embase, and Google Scholar to find articles that were published up until May 2023. Inclusion criteria comprised observational studies reporting self-medication prevalence among pregnant women in India. Data were extracted using a standardized sheet, and a random-effects model was applied to determine the overall prevalence of self-medication using R software. The I2 statistic was employed to assess the heterogeneity among the studies.

RESULTS

This study analyzed eight studies with a collective sample size of 2208 pregnant women. The pooled prevalence of self-medication among pregnant Indian women was 19.3% (95% CI: 7.5%-41.3%; I2 = 99%; p < 0.01). Common self-treated conditions were cold, cough, fever, headache, and stomach disorders. Antipyretics, analgesics, antihistamines, and antacids were frequently used for self-medication. The perception of mild ailment, immediate alleviation, convenience, time savings, and advice from family, friends, or the media were all reasons for self-medication. Local pharmacies were the most usual source for obtaining drugs, and pharmacists, family, friends, and past prescriptions were common sources of medicine information.

CONCLUSIONS

A low yet substantial number of pregnant women in India are engaged in self-medication practices. Appropriate strategies need to be planned to reduce self-medication practices to attain sustainable developmental goals for maternal health in India.

The relation between eHealth literacy and healthy lifestyle behaviours in pregnant women

The aim of this study was to determine the relationship between eHealth literacy and healthy lifestyle behaviours among pregnant women. This cross-sectional study was conducted in five family health centres in a city in the western part of Turkey. The study sample consisted of 201 pregnant women who were admitted to the five family health centres between September and December 2022. A socio-demographic questionnaire, the eHealth Literacy Scale and the Healthy Lifestyle Behaviours in Pregnancy Scale were used to collect data. Multiple linear regression analysis was used to explore predictors of health-promoting behaviours. The mean score of the eHealth Literacy Scale was 29.37 ± 6.20. The mean score of the Healthy Lifestyle Behaviours Scale was 119.69 ± 13.58. Multiple linear regression showed that predictors of healthy lifestyle behaviours among pregnant women were eHealth literacy, using internet to access health information and gestational age. eHealth literacy was found to be an important factor affecting the healthy lifestyle behaviours of pregnant women. This study highlights the importance of considering pregnant women's eHealth literacy in interventions aimed at improving healthy lifestyle behaviours.

Prevalence and social determinants of periodontal disease in Colombian pregnant women

OBJECTIVE

The objective of the study was to identify the prevalence of periodontal disease in pregnant women in the Colombian population and its association with social determinants and medical history based on data from the Fourth National Oral Health Survey (ENSAB IV).

METHODS

A total of 1012 pregnant women from different areas of Colombia were evaluated. A periodontal evaluation was performed using a North Carolina periodontal probe. The following data were recorded: number of teeth, probing depth (PD), the position of the gingival margin (GM) and clinical attachment level (CAL). An ordinal logistic regression analysis was performed for the association between social determinants and the Centers for Disease Control and Prevention and the American Academy of Periodontology (CDC/AAP) classification and logistic regression between social determinants and the European Federation of Periodontology (EFP) classification.

RESULTS

The prevalence of periodontitis was 37.1% using the CDC/AAP criteria and 41.2% according to the criteria of EFP distributed in sensitive (40.2%) and specific cases (0.9%). Age, belonging to a subsidized regime, living in a rural area, having an intermittent water supply and bleeding in medical records were found to be positively associated with periodontitis (mild, moderate, severe).

CONCLUSIONS

The findings of this national study of pregnant women show a high prevalence of periodontitis-using the CDC/AAP and EFP criteria-associated with age, living in rural areas, subsidized regime, intermittent water supply and bleeding in medical records.

Heat stress and adverse pregnancy outcome: Prospective cohort study

OBJECTIVE

To explore the relationship between occupational heat exposure, physiological heat strain indicators and adverse outcomes in pregnant women.

DESIGN

Prospective cohort.

SETTING

Workplaces in Tamil Nadu, India.

SAMPLE

A cohort of 800 pregnant women engaged in moderate to heavy physical work in 2017-2019 and 2021-2022.

METHODS

Participants were recruited at between 8 and 14 weeks of gestation. Occupational heat exposure and heat strain indicators were captured each trimester. 'Heat exposed' was defined as heat stress exceeding the threshold limit value (TLV) for safe manual work (with maximum wet-bulb globe temperatures of 27.5°C for a heavy workload and 28.0°C for a moderate workload). Physiological heat strain indicators (HSIs) such as core body temperature (CBT) and urine specific gravity (USG) were measured before and after each shift. Heat-related health symptoms were captured using the modified HOTHAPS questionnaire.

MAIN OUTCOME MEASURES

The main outcome measures included (1) a composite measure of any adverse pregnancy outcome (APO) during pregnancy (including miscarriage, preterm birth, low birthweight, stillbirth, intrauterine growth restriction and birth defects), (2) a composite measure of adverse outcomes at birth (3) and miscarriage.

RESULTS

Of the 800 participants, 47.3% had high occupational heat exposure. A rise in CBT was recorded in 17.4% of exposed workers, and 29.6% of workers experienced moderate dehydration (USG ≥ 1.020). Heat-exposed women had a doubled risk of miscarriage (adjusted odds ratio, aOR 2.4; 95% confidence interval, 95% CI 1.0-5.7). High occupational heat exposure was associated with an increased risk of any adverse pregnancy and foetal outcome (aOR 2.3; 95% CI 1.4-3.8) and adverse outcome at birth (aOR 2.0; 95% CI 1.2-3.3).

CONCLUSIONS

High occupational heat exposure is associated with HSIs and adverse pregnancy outcomes in India.

A Study of Fluid Intake, Hydration Status, and Body Composition of Pregnant Women in Their Third Trimester, and Relationships with Their Infant's Birth Weight in China: A Prospective Cohort Study

BACKGROUND

Water intake and hydration status may potentially influence maternal and child health. However, there is little research regarding this topic.

OBJECTIVES

This study aimed to investigate pregnant women's total fluid intake (TFI) levels, hydration status, and body composition and further explore their relationship with infant birth weight.

METHODS

A 7-day, 24 h fluid intake recorded was applied to determine participants' TFI levels. Morning urine samples were collected and tested to evaluate their hydration status. Maternal body compositions in their third trimester and infant birth weights were measured.

RESULTS

A total of 380 participants completed the study. The TFI was insufficient for pregnant women during their third trimester (median = 1574 mL), with only 12.1% of participants meeting the recommended adequate fluid intake level for pregnant women living in China (1.7 L per day). With the increasing TFI values, the urine osmolality decreased, which showed statistical significance among the four groups (χ2 = 22.637, p < 0.05). The participants displayed a poor hydration status. Meanwhile, the percentage of participants who were in dehydrated status decreased (χ2 = 67.618, p < 0.05), while body water content and basal metabolic rate increased with the increase in TFI levels (χ2 = 20.784, p < 0.05; χ2 = 14.026, p < 0.05). There were positive linear relationships between plain water intake, the basal metabolic rate of pregnant women and their infant birth weight (SE = 0.153, p < 0.05; SE = 0.076, p < 0.05).

CONCLUSIONS

Water intake was insufficient, and poor hydration status was common among pregnant women in China. There may be potential relationships between plain water intake, basal metabolic rate, and infant birth weight.

Before and after study of a national complementary and supplementary feeding programme in Rwanda, 2017-2021

To address high rates of malnutrition among children from vulnerable households in Rwanda, the government initiated a national food supplementation programme. A before and after evaluation, using repeat cross-sectional surveys in randomly selected villages was conducted; aimed at assessing the effectiveness of providing fortified blended food (FBF) to children 18-23 months of age, pregnant and lactating women in the lowest tier of Rwanda's social support system. Data were collected in 2017, 2018 and 2021 through interviews with caregivers; anthropometric measurements and a capillary blood sample were obtained from children. The primary statistical analysis compared the nutritional status of children before and after the introduction of FBF. We enroled 724 children during each survey. The prevalence of stunting declined from 47% to 35% between 2017 and 2021; in 2018, the prevalence of stunting was 43%. Children had a 42% reduction in the odds of being stunted (adjusted odds ratio [AOR]: 0.58, 95% confidence interval [CI]: 0.47-0.74, p < 0.001) from 2017 to 2021 even after adjusting for inherent, distal, proximal, and intermediate covariates. The reduction in stunting observed within the first year of the programme was not statistically significant (AOR: 0.83, 95% CI: 0.67-1.03, p < 0.091). We observed meaningful reductions in the prevalence of stunting among children which coincided with the introduction of Government-led initiative to reduce malnutrition. The Rwandan Government has committed to improving the living conditions of vulnerable households and has made strong investments in reducing malnutrition. The impact of these investments can be seen in the overall trend towards improved nutritional status highlighted in this evaluation.

The cost-effectiveness of syphilis screening in pregnant women: a systematic literature review

Introduction

The cost-effectiveness study of syphilis screening in pregnant women has not been synthesized. This study aimed to synthesize the economic evidence on the cost-effectiveness of syphilis screening in pregnant women that might contribute to making recommendations on the future direction of syphilis screening approaches.

Methods

We systematically searched MEDLINE, PubMed, and Web of Science databases for relevant studies published before 19 January 2023 and identified the cost-effectiveness analyses for syphilis screening in pregnant women. The methodological design quality was appraised by the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) 2022 checklist.

Results

In total, 17 literature met the eligibility criteria for a full review. Of the 17 studies, four evaluated interventions using different screening methods, seven assessed a combination of syphilis testing and treatment interventions, three focused on repeat screening intervention, and four evaluated the interventions that integrated syphilis and HIV testing. The most cost-effective strategy appeared to be rapid syphilis testing with high treatment rates in pregnant women who were positive.

Discussion

The cost-effectiveness of syphilis screening for pregnancy has been widely demonstrated. It is very essential to improve the compliance with maternal screening and the treatment rates for positive pregnant women while implementing screening.

Difficulty in Serologic Screening for Subclinical Rubella during Pregnancy

In Japan, rubella antibodies are tested in all pregnant women to detect subclinical infections. This study aimed to assess the validity of measuring rubella antibodies for detecting subclinical rubella among pregnant women in Japan. This single-center retrospective study measured rubella hemagglutination inhibition (HI) titers and rubella-specific IgM antibody index (IgM) values. IgM values were measured by conducting enzyme immunoassay, and IgM-values >1.2 were considered positive. Of 14,965 included pregnant women, 186 (1.2%) were IgM-positive. Only one patient was clinically diagnosed with rubella (HI titer, 1:2,048; IgM value, 10) and developed fever and skin rash. She decided to terminate her pregnancy without undergoing repeated blood tests. Of the IgM-positive patients, 136 (73.1%) had rubella HI titers of < 1:256. The correlation coefficient between rubella HI and IgM titers was weakly positive (0.2527; P < 0.0001). This study showed that a single combination of rubella HI and rubella-specific IgM measurements alone could not detect subclinical rubella. Creating awareness among pregnant women by informing them that almost all rubella-specific IgM-positive individuals without symptoms are not acutely infected could decrease their anxiety and prevent unnecessary pregnancy termination.

Understanding Fijian health system challenges in the prevention of mother-to-child transmission of HIV services in the three tertiary hospitals in Fiji

Mother-to-child transmission is the most common route of human immunodeficiency virus transmission in children, which could be prevented with proper treatment and access to care. Health system challenges can impede the effectiveness of prevention of mother-to-child transmission (PMTCT) programmes. We aim to understand the health system challenges to the provision of PMTCT services for pregnant women in three tertiary hospitals in Fiji. Data were collected using in-depth interviews in the three tertiary hospitals and associated health clinics in Fiji between April-May 2013 and February-March 2014. Ethical approvals were obtained. A total of 58 healthcare providers were interviewed including doctors (n = 12), midwives (n = 19), nurses (n = 14), laboratory technicians (n = 5) and counsellors (n = 8). The data were analysed using thematic analysis. We found that the healthcare workers faced a wide range of health system challenges including institutional and human resource challenges. Staff shortage, limited PMTCT training and shortage of supplies were barriers to the quality of PMTCT services. Our findings would be useful in developing strategies to overcome barriers as it would be imperative in improving the quality of PMTCT service provision in Fiji and other similar settings.

Emergency medical team interventions in Poland during out-of-hospital deliveries: A retrospective analysis

BACKGROUND

Emergency medical teams are a crucial component of healthcare systems, routinely providing essential care to pregnant patients in various situations.

OBJECTIVES

To evaluate the rate and outcomes of out-of-hospital deliveries attended by Emergency Medical Services (EMS) in Poland and identify areas for improvement in the care provided by emergency medical teams.

MATERIAL AND METHODS

This retrospective study was based on 41,335 EMS emergency calls to women in advanced pregnancy, of which 879 births were delivered directly by medical teams between January 2018 and December 2022. Data were obtained from the Polish National Monitoring Center for Emergency Medical Services, encompassing all EMS interventions in Poland.

RESULTS

The study involved 879 EMS team interventions for pregnant women, with an average patient age of 29.87 years. Most patients were in their 2nd pregnancy (28.26%) and delivering for the 2nd time (25.77%). The postnatal condition of newborns, assessed using the Apgar score, was missing in 408 cases (46.52%) due to incorrect completion of documentation. Emergency Medical Services teams, predominantly P-type (basic) teams, handled 69.78% of deliveries, while S-type (specialist) teams were involved in 30.22% of cases. Medical procedures often performed during childbirth included manual assistance in spontaneous delivery, pulse oximetry, physical examination, examination of systemic blood pressure, obtaining peripheral intravenous access, and gynecological examination.

CONCLUSIONS

Given the rate of encountered cases and the gaps identified in medical documentation, there is merit in potentially implementing a dedicated form to be completed by medical teams when caring for a pregnant patient. Ongoing training and enhancements in the range of assistance provided to the mother and newborn are imperative for ensuring appropriate care.

The potential benefits of long-acting injectable cabotegravir in pregnant and breastfeeding women and their infants

BACKGROUND

Pregnant and breastfeeding women (PBW) in sub-Saharan Africa have high HIV incidence rates and associated risk of vertical transmission to their infants. Oral preexposure prophylaxis (PrEP) and injectable PrEP (long-acting cabotegravir, or CAB-LA) can potentially reduce this HIV transmission, but population-level impacts are uncertain.

METHODS

We extended a previously developed model of HIV and PrEP in South Africa to allow for variable PrEP duration and preference in PBW. We considered three potential scenarios for PrEP provision to PBW: oral PrEP only, CAB-LA only, and allowing oral/CAB-LA choice, with uptake and retention assumptions informed by South African data, each compared with a 'base' scenario without PrEP for PBW.

RESULTS

Without PrEP for PBW, the model estimates 1.31 million new infections will occur between 2025 and 2035 in South African adults and children, including 100 000 in PBW, 16 800 in infants at/before birth, and 35 200 in children through breastmilk. In the oral PrEP-only scenario, these numbers would reduce by 1.2% (95% CI: 0.7-1.7%), 8.6% (4.8-12.9%), 4.0% (2.1-5.8%), and 5.3% (3.0-8.2%) respectively. In the CAB-LA-only scenario, the corresponding reductions would be 6.1% (2.9-9.6%), 41.2% (19.8-65.0%), 12.6% (6.0-19.4%), and 29.5% (13.9-46.8%), respectively, and in the oral/CAB-LA choice scenario, similar reductions would be achieved [5.6% (3.4-8.0%), 39% (23.4-55.9%), 12.4% (7.4-16.8%) and 27.6% (16.5-39.9%) respectively].

CONCLUSION

CAB-LA has the potential to be substantially more effective than oral PrEP in preventing HIV acquisition in PBW and vertical transmission, and can also modestly reduce HIV incidence at a population level.

Socioeconomic inequality in timing of ANC visit among pregnant women in Ethiopia, 2019

Background

Antenatal care (ANC) remains an invaluable approach to preventive care for ensuring maternal and infant health outcomes. Women in sub-Saharan Africa tend to delay their first antenatal care visits. In Ethiopia, only 20% of women received their first antenatal care during the first trimester of pregnancy. Timely and appropriate antenatal care practices can potentially save the lives of both mothers and children. Understanding socioeconomic inequality in the timing of antenatal care visits and its determinants may contribute to tackling disparities and achieving the sustainable development goals for maternal health.

Objective

This study aimed to assess the socioeconomic inequality in the timing of antenatal care visit.

Method

Secondary data sourced from the Mini Ethiopian Demographic Health Survey 2019 were used for this study. A total of 2,906 pregnant women were included in the study, and concentration curves were used to show inequality among sociodemographic and economic variables. Decomposition analysis was performed to estimate the contribution of each independent variable to the inequality in the timing of antenatal care visits.

Result

The estimate of early initiation of antenatal care was 63%. The concentration index was 0.18 (P < 0.001). The inequality in the timing of antenatal care visit was more concentrated among the wealthiest pregnant women with a concentration index value of 0.18 (P < 0.001). Based on decomposition analysis results, the wealth index (81.9%.), education status (22.29%), and region (0.0642%) were identified as contributing factors to the inequality in the timing of antenatal care visits among women.

Conclusion

The wealth index, educational status, and region were significant contributors to inequality in the early initiation of antenatal care visit. Improving women's wealth and education and narrowing the inequality gap are crucial for improving the health status of women and their children. We should focus on interventions targeted at early antenatal care visit to address the determinants of socioeconomic inequities.

Characteristics and Outcomes of Coronavirus Disease- 2019 Among Pregnant Women in Saudi Arabia; a Retrospective Study

Background

Pregnancy-related coronavirus disease 2019 infection ranges from asymptomatic to very serious illness. This study aimed to determine the impact of the COVID-19 infection on pregnant women in the Jazan region of Saudi Arabia.

Methods

Retrospective observational study of women who had COVID-19 positive test in pregnancy admitted in King Fahd Hospital, Abu Arish General Hospital, and Sabya General Hospital, Jazan, Saudi Arabia during the period between March 2020 and March 2022. Data were extracted from the patient's records. Frequency and percentage distributions were calculated for categorical variables. Descriptive studies and regression analysis were conducted to evaluate the association between selected variables and pregnancy outcomes.

Results

Of the 33 pregnant women with confirmed infection, the majority were in their second and third trimester, with approximately 42.4% requiring intensive care unit (ICU) admission and oxygen therapy. The most prevalent symptoms were high respiratory rate and low blood pressure, often accompanied by fever, cough, and shortness of breath. Live births resulted in 54.5% of the cases, while two maternal deaths were reported. Significant associations were found between the need for non-invasive ventilation and timing of infection (p = 0.026), the mode of delivery and timing of infection (p = 0.036), and the mode of delivery and body mass index (BMI) (p = 0.007).

Conclusion

COVID-19 poses significant risks to pregnant women, particularly in the third trimester, and emphasized the importance of early identification of high-risk pregnancies, strategic planning, and enhanced monitoring during antenatal care.

Exposure to air pollution as a risk factor for anaemia: a global scoping review

Anaemia is an important global health issue with various factors responsible for its occurrence. Though nutritional deficiency is one of the main causes of the disease, evidence suggests a potential link between long-term exposure to ambient air pollution and an increased risk of developing anaemia. Our scoping review evaluates studies conducted across the world to examine possible associations between anaemia and ambient air pollution. Six databases were searched, 153 sources were identified, and 21 articles were included in the review. Apart from one article which showed no significant effect, studies reported positive associations between anaemia and air pollution. This was true for both indoor and outdoor air pollution, various types of particulate matter exposure, and across demographic groups. The review highlights the importance of recognizing exposure to air pollution as a potential risk factor for anaemia and emphasizes the imperative for focused interventions and policy measures to mitigate air pollution.

Tenofovir alafenamide or tenofovir disoproxil fumarate in pregnancy to prevent HBV transmission: Maternal ALT trajectory and infant outcomes

BACKGROUND

The use of antiviral agents, specifically tenofovir disoproxil fumarate (TDF), in pregnant women to prevent mother-to-child HBV transmission is a key step towards hepatitis elimination. However, data on using tenofovir alafenamide (TAF) is insufficient. The frequent occurrence of postpartum ALT flares may impact the clinical implementation.

METHODS

The maternal and infant outcomes were compared in multi-centre trials of high viral load HBsAg/HBeAg+ pregnant women receiving TAF or TDF from the third trimester until 2 weeks postpartum with intensive follow-ups. To explore the dynamic pre- and postpartum changes in ALT levels, we used a group-based trajectory model for analysing data of 332 women from three prospective studies.

RESULTS

After treatment, the maternal HBV DNA levels significantly decreased from baseline to delivery: 7.87 ± 0.59 to 3.99 ± 1.07 Log10 IU/mL TAF (n = 78) and 8.30 ± 0.36 to 4.47 ± 0.86 Log10 IU/mL (TDF, n = 53), with viral load reductions of 3.87 versus 3.83 Log10 IU/mL. The HBsAg-positive rates among 12-month-old infants were 1.28% (1/78) versus 1.82% (1/55) respectively (p = 1.00). Of the TAF or TDF-treated mothers, 25.64% versus 16.98% experienced ALT > 2X ULN, and 11.54% versus 1.89% received extended antiviral treatment. Our model revealed four distinct ALT patterns: stable ALT (87.2%), moderate (8.0%) or marked (2.4%) postpartum flares, or prepartum elevations (2.4%).

CONCLUSIONS

TAF effectively reduces mother-to-child HBV transmission, but prophylaxis failure still occurred in few cases. Postpartum ALT flares are common in women receiving TAF or TDF during pregnancy. Approximately 12.8% of mothers may require extended postpartum antiviral treatment.

Effects of COVID-19 infection risk perception on depressive symptoms among pregnant women in different periods of the COVID-19 pandemic in China: A mediation model

OBJECTIVE

The study investigated the mediation mechanisms between coronavirus disease 2019 (COVID-19) infection risk perception and depressive symptoms among pregnant women during the different periods of the COVID-19 pandemic.

METHODS

Study data were derived from a sample of 463 pregnant women in Hubei Province, the province with the most severe COVID-19 outbreak in China. Data were collected in two phases (during and after the acute phase of the COVID-19 pandemic) using the COVID-19 infection risk perception scales, the Edinburg Postnatal Depression Scale (EPDS), the Perceived Stress Scale (PSS), and the Peritrauma Distress Inventory (PDI). Mediation model analysis was used for data analysis, overall and by groups.

RESULTS

The level of depressive symptoms among pregnant women after the acute phase of the COVID-19 pandemic was moderate (median, 9.00 [25th percentile, 75th percentile = 5.00, 12.00]), higher than the acute group (median, 7.00 [25th percentile, 75th percentile = 4.50, 10.00]). Perceived stress and traumatic stress fully mediated the relationship between infection worry (total indirect effect, 0.39 [95% confidence interval, 0.24-0.54])/infection possibility (total indirect effect, 0.41 [95% confidence interval, 0.22-0.61]) and depressive symptoms among pregnant women during the acute phase of the COVID-19 pandemic, whereas the relationship was only fully mediated by perceived stress after the acute pandemic.

CONCLUSIONS

Effects of risk perception on depressive symptoms varied by periods of COVID-19. These findings have important implications for developing effective prevention and early psychoeducational intervention strategies for pregnant women with a high risk of depressive symptoms during different periods of emerging infectious diseases.

Characteristics and Outcomes of Pregnant Women Hospitalized With Laboratory-Confirmed Respiratory Syncytial Virus Before and During the COVID-19 Pandemic

Background

Respiratory syncytial virus (RSV) can cause severe disease among infants and older adults. Less is known about RSV among pregnant women.

Methods

To analyze hospitalizations with laboratory-confirmed RSV among women aged 18 to 49 years, we used data from the RSV Hospitalization Surveillance Network (RSV-NET), a multistate population-based surveillance system. Specifically, we compared characteristics and outcomes among (1) pregnant and nonpregnant women during the pre-COVID-19 pandemic period (2014-2018), (2) pregnant women with respiratory symptoms during the prepandemic and pandemic periods (2021-2023), and (3) pregnant women with and without respiratory symptoms in the pandemic period. Using multivariable logistic regression, we examined whether pregnancy was a risk factor for severe outcomes (intensive care unit admission or in-hospital death) among women aged 18 to 49 years who were hospitalized with RSV prepandemic.

Results

Prepandemic, 387 women aged 18 to 49 years were hospitalized with RSV. Of those, 350 (90.4%) had respiratory symptoms, among whom 33 (9.4%) were pregnant. Five (15.2%) pregnant women and 74 (23.3%) nonpregnant women were admitted to the intensive care unit; no pregnant women and 5 (1.6%) nonpregnant women died. Among 279 hospitalized pregnant women, 41 were identified prepandemic and 238 during the pandemic: 80.5% and 35.3% had respiratory symptoms, respectively (P < .001). Pregnant women were more likely to deliver during their RSV-associated hospitalization during the pandemic vs the prepandemic period (73.1% vs 43.9%, P < .001).

Conclusions

Few pregnant women had severe RSV disease, and pregnancy was not a risk factor for a severe outcome. More asymptomatic pregnant women were identified during the pandemic, likely due to changes in testing practices for RSV.

Can EPDS and EPDS-3A be used to replace GAD-7 to screen the anxiety of pregnant women during pregnancy examination?

OBJECTIVE

To examine the screening ability and cut-off scores of the Edinburgh Postnatal Depression Scale (EPDS) and EPDS-3A for pregnancy anxiety in pregnancy examination.

METHODS

This was a prospective repetitive measurement study. A follow-up survey was performed in Chinese pregnant women with the EPDS, the 7-item Generalized Anxiety Disorder (GAD-7) scale and a basic information questionnaire. A total of 609 women participated in all surveys at three trimesters, and all data were complete with no missing values. Receiver operating characteristic curves, Cohen's kappa and cross-tabulation were used to test the single and combined screening ability of EPDS and EPDS-3A for pregnancy anxiety.

RESULTS

The areas under the curves of EPDS and EPDS-3A were close to or more than 0.90. EPDS scores greater than 14 in the first trimester and greater than 13 in the second and third trimesters could be used as the cut-off values. EPDS-3A score greater than 4 could be used as the cut-off value in each trimester. Adding the EPDS-3A to the EPDS would lead to correct identification of an additional 6.33%, 6.35%, and 7.25% of anxious women and misdiagnosis of an additional 6.60%, 2.56%, and 2.41% of normal women in each trimester, respectively.

CONCLUSION

The EPDS and EPDS-3A can be used alone or in combination for initially screening of pregnancy anxiety. Under certain conditions, they can even be used to replace GAD-7 for anxiety screening to reduce the adverse influence of excessive screening on pregnant women, and improve the quality of survey data and efficiency of clinical services.

Predictors of physical inactivity among pregnant women

It is recommended that pregnant women be physically active to promote maternal and child health. This study aimed to explore the prevalence of physical inactivity and its modifiable predictors in the three trimesters in Chinese pregnant women. Four hundred forty-four pregnant women completed the Pregnant Physical Activity Questionnaire in the first, second, and third trimesters. The prevalence of physical inactivity reached its highest (66.2%) in the first trimester and lowest (19.4%) in the second trimester. Pregnant women with inadequate physical activity knowledge and low self-efficacy were at higher risk for physical inactivity. Monitoring physical inactivity could be incorporated into antenatal care and start from the first trimester. Prenatal care professionals should take action to increase pregnant women's physical activity self-efficacy and knowledge to enhance their physical activity.

Dietary diversity practice and its associated factors among pregnant women in Eastern Ethiopia: A community-based cross-sectional study

Micronutrient insufficiencies during pregnancy have a marked impact on the health of the woman and her offspring. Evidence about the dietary practice of pregnant women is limited in Ethiopia, particularly in drought-prone areas where food insecurity is widely seen. Therefore, this research aimed to assess the dietary diversity practice and associated factors among pregnant women in Chiro district, Eastern Ethiopia. We employed a community-based cross-sectional survey in Chiro district, Eastern Ethiopia. The data were collected from 417 randomly selected pregnant women using an interview-administered structured questionnaire. EpiData-3.1 and STATA-14 were used for data entry and analysis, respectively. The binary logistic regression analysis was deployed to assess the association between dietary diversity practice and predictor variables. Out of 420 calculated sample size, 417 pregnant women completed the survey giving a response rate of 99.3%. The overall prevalence of optimal dietary diversity was 38.4% (95% CI: 33.7%, 43.2%). Educational status (adjusted odds ratio [AOR]: 2.71, 95% CI: 1.08, 6.81), meal frequency (AOR: 1.91, 95% CI: 1.11, 3.28), home gardening (AOR: 4.21, 95% CI: 2.48, 7.16), and household food security (AOR: 0.23, 95% CI: 0.13, 0.40) were independent predictors of dietary diversity practice.This study found that a substantial proportion of pregnant women had suboptimal dietary diversity, indicating a fundamental micronutrient inadequacy. Educational status, meal frequency, home gardening practice, and household food security were independent determinants of dietary diversity practice. The findings suggest that promoting maternal education and home gardening practice, and controlling food insecurity might enhance optimal dietary diversity.

Mediterranean Diet Adherence and Health-Related Quality of Life during Pregnancy: Is the Mediterranean Diet Beneficial in Non-Mediterranean Countries?

This study aimed to examine the association of Mediterranean diet (MD) adherence and MD components with health-related quality of life (HRQoL) in pregnant women from Spain and Sweden. A total of 138 pregnant women from Spain (age: 32.9 ± 4.6 years old) and 302 pregnant women from Sweden (age: 31.3 ± 4.1 years old) were included. MD adherence was assessed with the Mediterranean food pattern (i.e., a MD index) at the 14-16th gestational weeks. HRQoL was assessed with the Spanish and Swedish versions of the 36-item Short-Form Health Survey (SF-36 and RAND-36, respectively) at the 14-16th and 34-37th gestational weeks. A greater MD adherence was associated with better physical functioning, bodily pain, vitality, emotional role, and mental health in cross-sectional associations (2nd trimester) in the Spanish sample (all p < 0.05). Furthermore, a greater MD adherence was associated with lower bodily pain in both Spanish and Swedish samples (both p < 0.05) in the 3rd trimester. The associations of MD adherence with pain seem to be explained by a greater intake of fiber, fish, fruits, nuts, and legumes (all p < 0.05). A greater MD adherence, driven by a higher intake of fiber, fish, fruits, nuts, and legumes, was associated with lower pain throughout pregnancy in both Mediterranean and non-Mediterranean populations.

Sociodemographic and obstetric factors associated with health-related quality of life of high-risk pregnant women

OBJECTIVE

To evaluate the association between sociodemographic and obstetric factors and the health-related quality of life of pregnant women in high-risk prenatal care.

METHODS

A cross-sectional study of women in high-risk prenatal care in Ceara, Brazil. The investigated outcomes were health-related quality of life, using the Medical Outcomes Study 36-item short-form health survey; the investigated covariates were sociodemographic and obstetric data. Associative analyses were performed using the Jamovi® software version 0.9.

RESULTS

Of the 276 women included in the study, women with the following characteristics presented a better quality of life in some domain of the scale: age equal to or greater than 35 years, higher income per dependent, religious, living with three or fewer persons, with their own home, in primigestation, nulliparous, with no history of previous abortion, and with up to two living children. The regression model showed an association between the total scale score, which means a higher quality of life in women with age equal to or greater than 35 years and a higher income per dependent.

CONCLUSION

The study identified sociodemographic and obstetric factors that may affect the quality of life of high-risk pregnant women, providing subsidies to health providers so that they can promote better prenatal care.

The gut microbiota composition and metabolites are different in women with hypertensive disorders of pregnancy and normotension: A pilot study

INTRODUCTION

Hypertensive disorders of pregnancy (HDP) are one of the main causes of perinatal morbidity. Gut microbiota influences host inflammatory pathways, glucose, and lipid metabolism. However, there is a lack of studies available on gut microbiota in HDP.

OBJECTIVES

We investigate the mechanistic and pathogenic role of microbiota in the development of HDP, and want to treat HDP with gut microbiota.

METHODS

We performed a case-control study to compare fecal samples of HDP and normotensive pregnant women by 16S ribosomal RNA sequencing. Fecal samples, collected from pregnant women, were divided into groups P and C (pregnant women with HDP and normotension, respectively). There were six pregnant women in group P and nine pregnant women in group C. Age of pregnant women is from 18 to 40 years and gestational age is from 27 to 40 weeks. DNA was extracted from fecal samples; a gene library was constructed and analyzed using bioinformatics. Finally, we determined the changes in the microbiome by alpha diversity, beta diversity, classification abundance, and taxonomic composition analyses.

RESULTS

Escherichia (10.48% in group P and 0.61% in group C) was the dominant bacterium in HDP patients by classification abundance analysis, which can lead to the development of preeclampsia through inflammatory response. We found that pregnant women with HDP had higher abundance of Rothia (p = 0.04984), Actinomyces (p = 0.02040), and Enterococcus (p = 0.04974) and lower abundance of Coprococcus (p = 0.04955) than pregnant women with normotension for the first time by taxonomic composition analysis. Based on the Kyoto Encyclopedia of Genes and Genomes database analysis, physiological and biochemical functions of HDP patients were significantly weakened, especially in energy metabolism.

CONCLUSIONS

We found the effect of changes in gut microbiota on the development of HDP. In comparison with group C, group P contained more harmful bacteria and less beneficial bacteria, which are associated with HDP. Our research further provides a basis for a clinical application for HDP treatment using antibiotics and probiotic supplementation.

Mycoplasma hominis increases the risk for Ureaplasma parvum infection in Human immunodeficiency virus infected pregnant women

INTRODUCTION

Mycoplasma hominis and Ureaplasma parvum have been recently linked to sexually transmitted diseases and other conditions. There are a limited number of studies conducted on South African pregnant women that have assessed the prevalence and risk factors for genital mycoplasmas.

METHODOLOGY

This study included 264 HIV infected pregnant women attending the King Edward VIII antenatal clinic in eThekwini, South Africa. DNA was extracted using the PureLink Microbiome kit and pathogens were detected using the TaqMan Real-time PCR assays. The statistical data analysis was conducted in a freely available Statistical Computing Environment, R software, version 3.6.3 using the RStudio platform.

RESULTS

The prevalence of M. hominis and U. parvum, was 215/264 (81.4%), and 203/264 (76.9%), respectively. In the M. hominis positive group, a significantly (p = 0.004) higher proportion, 80.5% tested positive for U. parvum infection when compared to 61.2% among the M. hominis negative. Of the U. parvum positive women, a significantly (p = 0.004) higher proportion of women (85.2%) tested positive for M. hominis when compared to 68.9% among the U. parvum negative. In the unadjusted and adjusted analysis, being M. hominis positive increased the risk for U. parvum by approximately 3 times more (p = 0.014) and 4-fold (p = 0.008), respectively.

CONCLUSIONS

This study showed a significant link between M. hominis and U. parvum infection. To date, there are a limited number of studies that have investigated M. hominisbeing a risk factor for U. parvum infection. Therefore, the data presented in the current study now fills in this gap in the literature.

Perspectives of pregnant women on maternal health information handouts at KwaZulu-Natal sub-district

BACKGROUND

Maternal health information handouts are used by midwives to facilitate health education of pregnant women during their antenatal care (ANC) period. South Africa's Saving Mothers Report 2014 showed that delay in accessing medical help, as a patient-related avoidable factor, accounted for 27% of maternal and neonatal mortality.

AIM

To ascertain the perceptions of pregnant women attending ANC in the Msunduzi sub-district in uMgungundlovu District, towards the maternal health information handouts.

SETTING

The study was conducted at three primary health care (PHC) clinics (two PHC and one CHC [Community Health Care]) that provided ANC in the Msunduzi sub-district KwaZulu-Natal, in 2019.

METHODS

Using a qualitative approach, focus group discussions (FGDs) were conducted with 10 participants from each clinic. Data were transcribed and analysed using thematic analysis.

RESULTS

The themes explored included: availability and access of handouts, usefulness, review of handouts, alternative methods available, and family involvement.

CONCLUSION

The authors concluded that although the maternal information handouts were given to the mothers during their maternal health visits, few of them were aware of these handouts. New strategies should be employed to deliver this vital information, as suggested by mothers.Contribution: The awareness of pregnant mothers about the information handouts contributes to the positive perinatal outcomes at clinic levels.

The effect of classical foot massage on insomnia and anxiety in preeclamptic pregnant women: a randomized controlled study

OBJECTIVE

Preeclampsia is one of the most common complaints during pregnancy. Preeclamptic pregnant women may experience insomnia and anxiety.

METHODS

This study was a randomized controlled trial with 71 preeclamptic women. In the experimental group, a foot massage was done for 3 days in a week. In the control group, any applications were not done. These groups were assessed for insomnia and anxiety levels.

RESULTS

In this study, it was found that classical foot massage significantly reduced (12.45±5.74 vs. 33.4±6.41) insomnia and anxiety compared with the control group (18.8±6.44 vs. 39.19±8.31, respectively, p<0.05).

CONCLUSION

The classical foot massage can effectively decrease insomnia and anxiety symptoms.

Physical activity and associated factors in Australian women during pregnancy: A cross-sectional study

ISSUE ADDRESSED

Whilst the benefits of regular physical activity during pregnancy are well known, the few studies conducted in Australian pregnant women suggest that most do not meet recommended exercise guidelines. The aim of this study was to determine the levels of physical activity, sedentary behaviours, and associated factors in Australian pregnant women.

METHODS

A random sample of pregnant women (N = 780) of (mean [SD]) 31 (5) years of age completed a questionnaire describing weekly physical activity and sedentary behaviours. A number of potential risk factors, including socio-demographic characteristics and ethnicity, were investigated using logistic regression.

RESULTS

Approximately one-third (34%) of women were classified as "active"; however, only 7% of women performed the recommended amount of physical activity according to Australian guidelines. Women reported (mean [95% CI]) sitting for 8 (7.8-8.2) hours and lying down during the day for 0.5 (0.5-0.6) hour while pregnant. Being university educated (OR [95% CI]) (2.87 [1.6-4.9]), in paid employment (2.12 [1.14-3.94]) and having a lower body mass index (0.91 [0.87-0.95]) were factors associated with being active.

CONCLUSION

Australian women performed low levels of physical activity during pregnancy and spend long periods of time in sedentary behaviours. SO WHAT?: There is a strong need for a concerted health promotion strategy to endorse increased physical activity, along with a reduction in sedentary behaviours, during pregnancy to support better maternal outcomes in Australia.

Inadequate food diversity and food taboo associated with maternal iron deficiency among pregnant women living in slum settlements in Makassar City, Indonesia

BACKGROUND

Anemia in pregnancy is a major public health problem, especially in developing countries. The most common cause is nutritional deficiencies, especially iron deficiency. Adequate nutritional intake from food is essential during pregnancy. Therefore, this study aimed to investigate the relationship between food access and intake patterns with the incidence of iron deficiency among pregnant women living in the slum settlement in Makassar City.

MATERIALS AND METHODS

This research is a sub-study of the Indonesian Birth Cohort Study based in Makassar City. This sub-study used a cross-sectional design and recruited 173 pregnant women in their second and third trimesters using total sampling. All data were collected using a structured questionnaire and recorded using KoboToolbox software. Serum ferritin levels were examined for iron status using the ELISA method at the Microbiology Laboratory Unit at Hasanuddin University Teaching Hospital. The statistical data were analyzed using STATA version 14 with Chi-square analysis and logistic regression.

RESULTS

The prevalence of iron deficiency in pregnant women living in slum settlements in Makassar City was 78%. Logistic regression analysis showed that inadequate food diversity (AOR: 2.58; 95% CI: 1.17-5.69; P = 0.019) and food taboos (AOR: 2.81; 95% CI: 1.26-6.26; P = 0.011) were significantly associated with the incidence.

CONCLUSIONS

Most pregnant women living in slum settlements in Makassar City experienced iron deficiency. Pregnant women who experience iron shortages have been connected to food taboos and dietary diversity.

Significance of cervical secretion culture in predicting maternal and fetal outcome in pregnant women with premature rupture of membranes: a retrospective cohort study

Background: To investigate the clinical value of cervical secretion culture in pregnant women with premature rupture of membranes (PROM) in predicting maternal and fetal outcomes. Methods: We retrospectively reviewed clinical records of pregnant women who underwent obstetric examination and delivered in Fujian Maternal and Child Healthcare from December 2013 to December 2016. Pregnant women with a clear diagnosis of PROM, who underwent cervical secretion culture immediately after hospital admission were selected for the study. The primary outcome was the occurrence of chorioamnionitis. The secondary outcome was neonatal admission to the neonatal intensive care unit (NICU). Correlation between maternal and fetal outcomes and the results of the cervical secretion culture was analyzed by one-way analysis and multifactorial analysis, respectively. The predictive efficacy of cervical secretion culture was evaluated using receiver operating characteristic curve (ROC), area under the curve (AUC) and the integrated discrimination improvement (IDI). Results: A total of 7,727 pregnant women with PROM were included in the study. Of them, 1812 had positive cervical secretion cultures (635 positive for mycoplasma infection, 475 for bacterial, 637 for fungal, and 65 for chlamydial infections). Pregnant women with positive mycoplasma and bacterial cultures had higher rates of developing chorioamnionitis compared to women with negative cervical secretion cultures (9%, 12% vs. 1%, respectively). Similarly, positive mycoplasma and bacterial cultures were associated with higher rate of the preterm (before 34 weeks) labor (3%, 3% vs. 1% in women with negative cultures, respectively), and neonatal admission to the NICU (9%, 11% vs. 7%, respectively). After adjusting for various confounding factors, our analysis demonstrated that a positive cervical secretion culture for mycoplasma or bacterial pathogens remained an independent risk factor for chorioamnionitis. Cervical secretion culture outcome was less effective in predicting chorioamnionitis (AUC 0.569) compared to white blood count (WBC) (AUC 0.626) and C-reactive protein (CRP) levels (AUC 0.605). The IDI of the combined predictive model incorporating WBC, CRP, maternal fever and cervical secretion culture results was 0.0029. Conclusion: Positive cervical secretion cultures, especially for mycoplasma and bacteria, are associated with higher incidence of adverse maternal and fetal outcomes. However, the predictive value of this test is poor, and cannot be efficiently used for predicting chorioamnionitis.

Importance of Community Health Workers for Maternal Health Care Management

Objectives: Community Health Workers (CHWs) are important healthcare professionals and key members of team. The purpose of this research is to identify the roles and responsibilities of CHWs in developed and developing countries who provide healthcare assistance to pregnant and lactating women. Methods: For this particular study, a comparison was conducted between CHWs role in seven developed countries, seven South Asian developing countries, and India, with special emphasis on improving maternal health status. Results: CHW programs are essential in communities, institutional health programs, and outreach delivery systems. Without active community involvement, CHWs cannot reach their full potential. Developed countries have frameworks for CHWs, such as the Swasthya Shebika Program, Village Health Worker Cadret, Lady Health Worker Programme, and Accredited Social Health Activist program. CHWs are well-paid in developed nations and work with marginalized groups to spread health messages. However, up to 60% of community health workers in low- and lower-middle-income countries do not receive remuneration. Conclusion: Health systems must support CHWs in choosing technical interventions and providing necessary training, supervision, and logistical support.

Applying the WHO INSPIRE Framework to Ending Violence Against Pregnant Women and Unborn Children: A Case Study in Vietnam

This article adapted the INSPIRE framework, developed by the World Health Organization to prevent violence against children, to the systematic analysis of city-level healthcare services for pregnant women who experienced intimate partner violence. A mixed-methods study conducted in-depth interviews with 22 health and social care professionals and 140 pregnant women in Vietnam. The women were more likely to report limited system-level support for partners regarding violence and mental health, while the professionals perceived more weaknesses in policies and management of services. Traditional values tend to isolate abused women from receiving social services. The INSPIRE framework is innovative and could be applied in other contexts.

Change in Prevalence of Hepatitis B Virus Infection in Pregnant Women in the Last Two Decades in Thailand

Objectives: In Thailand, there has been a strategy to prevent the mother-to-child transmission of HBV for over 30 years. However, there is still a lack of empirical evidence regarding the effectiveness of this strategy. This study aims to investigate the trends in the prevalence of HBV infection in pregnant women and to identify factors that may be associated with the prevalence of HBV infection in pregnant women. Patients and Methods: A maternal-fetal medicine database was accessed to retrieve the consecutive obstetric records of women giving birth at Chiang Mai University Hospital, Thailand, from January 2003 to December 2022. All women undergoing HBV tests with available results were included for an analysis of the trends and changes in the prevalence of maternal HBV infection. Also, the rates of infection in different age cohorts were compared. Results: During the study period, a total of 36,958 women were eligible for analysis. Overall, the prevalence of HBV infection in pregnant women was found to be 5.3% (1970 cases). Overall, HBV prevalence fell from 6.11% in 2003 to 3.15% in 2022. There was a significant reduction, especially in the adolescent group, decreasing from 8.26% in 2003 to 0% in 2022. In the reproductive age group, the prevalence significantly decreased from 6.41% to 2.01%. However, the prevalence in the elderly group was unchanged. The only significant risk factor was the years in the early timeline of the study period, presumably associated with previous HBV vaccination. Other factors, such as socioeconomic status, residential area, and being a private case, were not correlated with the prevalence of HBV. Conclusion: The prevalence of HBV infection in pregnant women has significantly decreased in the past two decades from 6.11% in 2003 to 3.15% in 2022. The percentage of reduction was very striking in the adolescent group, dropping from 8.6% in 2003 to 0.0% in 2022 or being nearly eradicated in the most recent years. Our results suggest that the overall prevalence of HBV infection among our pregnant women will probably be less than 1.0% in the near future.

Antimicrobial Resistance Profile of Group B Streptococci Colonization in a Sample Population of Pregnant Women from Romania

Group B Streptococcus (GBS) represents one of the leading causes of life-threatening invasive disease in pregnant women and neonates. Rates of GBS colonization vary by region, but studies on maternal GBS status are limited in Romania. This study aims to identify the prevalence of colonization with GBS and whether the obstetrical characteristics are statistically associated with the study group's antimicrobial susceptibility patterns of tested GBS strains. This observational study was conducted between 1 May and 31 December 2021 at The Department of Obstetrics and Gynecology at Elias University Emergency Hospital (EUEH) in Bucharest, Romania. A total of 152 samples were positive for GBS and included in the study according to the inclusion criteria. As a result, the prevalence of colonized patients with GBS was 17.3%. GBS isolated in this population had the highest resistance to erythromycin (n = 38; 25%), followed by clindamycin (n = 36; 23.7%). Regarding the susceptibility patterns of tested strains to penicillin, the 152 susceptible strains had MIC breakpoints less than 0.06 μg/μL. The susceptibility patterns of tested strains to linezolid indicated three resistant strains with low levels of resistance (MICs ranging between 2 and 3 μg/μL). Multidrug resistance (at least three antibiotic classes) was not observed. In conclusion, although GBS naturally displays sensitivity to penicillin, the exact bacterial susceptibility testing should be performed in all cases where second-line therapy is taken into consideration for treatment. We acknowledge the need for future actions to limit multidrug-resistant bacteria.
