Review
BACKGROUND
Preconception health has the potential to improve parental, pregnancy and infant outcomes. This scoping review aims to (1) provide an overview of the strategies, policies, guidelines, frameworks, and recommendations available in the UK and Ireland that address preconception health and care, identifying common approaches and health-influencing factors that are targeted; and (2) conduct an audit to explore the awareness and use of resources found in the scoping review amongst healthcare professionals, to validate and contextualise findings relevant to Northern Ireland.
METHODS
Grey literature resources were identified through Google Advanced Search, NICE, OpenAire, ProQuest and relevant public health and government websites. Resources were included if published, reviewed, or updated between January 2011 and May 2022. Data were extracted into Excel and coded using NVivo. The review design included the involvement of the "Healthy Reproductive Years" Patient and Public Involvement and Engagement advisory panel.
RESULTS
The searches identified 273 resources, and a subsequent audit with healthcare professionals in Northern Ireland revealed five additional preconception health-related resources. A wide range of resource types were identified, and preconception health was often not the only focus of the resources reviewed. Resources proposed approaches to improve preconception health and care, such as the need for improved awareness and access to care, preconceptual counselling, multidisciplinary collaborations, and the adoption of a life-course approach. Many behavioural (e.g., folic acid intake, smoking), biomedical (e.g., mental and physical health conditions), and environmental and social (e.g., deprivation) factors were identified and addressed in the resources reviewed. In particular, pre-existing physical health conditions were frequently mentioned, with fewer resources addressing psychological factors and mental health. Overall, there was a greater focus on women's, rather than men's, behaviours.
CONCLUSIONS
This scoping review synthesised existing resources available in the UK and Ireland to identify a wide range of common approaches and factors that influence preconception health and care. Efforts are needed to implement the identified resources (e.g., strategies, guidelines) to support people of childbearing age to access preconception care and optimise their preconception health.

American Journal of Obstetrics and... Jun 2024To investigate the association between actual and planned modes of delivery, neonatal mortality, and short-term outcomes among preterm pregnancies ≤32 weeks of gestation. (Review)
Review
Cesarean delivery is associated with lower neonatal mortality among breech pregnancies - a systematic review and meta-analysis of preterm deliveries ≤32 weeks of gestation.
OBJECTIVE
To investigate the association between actual and planned modes of delivery, neonatal mortality, and short-term outcomes among preterm pregnancies ≤32 weeks of gestation.
DATA SOURCES
A systematic literature search was conducted in three main databases (PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) from inception to November 16, 2022. The protocol was registered in advance in the International Prospective Register of Systematic Reviews (CRD42022377870).
STUDY ELIGIBILITY CRITERIA
Eligible studies examined pregnancies ≤ 32nd gestational week. All infants received active care, and the outcomes were reported separately by different modes of delivery. Singleton and twin pregnancies at vertex and breech presentations were included. Studies that included pregnancies complicated with preeclampsia and abruptio placentae were excluded. Primary outcomes were neonatal mortality and intraventricular hemorrhage.
STUDY APPRAISAL AND SYNTHESIS METHODS
Articles were selected by title, abstract, and full text, and disagreements were resolved by consensus. Random effects model-based odds ratios with corresponding 95% confidence intervals were calculated for dichotomous outcomes. ROBINS-I was used to assess the risk of bias.
RESULTS
A total of nineteen observational studies were included involving a total of 16,042 preterm infants in this systematic review and meta-analysis. Actual cesarean delivery improves survival (odds ratio, 0.62; 95% confidence interval, 0.42 to 0.9) and decreases the incidence of intraventricular hemorrhage (odds ratio, 0.70; confidence interval, 0.57 to 0.85) compared to vaginal delivery. Planned cesarean delivery does not improve the survival of very and extremely preterm infants compared to vaginal delivery (odds ratio, 0.87; 95% confidence interval, 0.53 to 1.44). Subset analysis found significantly lower odds of death for singleton breech preterm deliveries born by both planned (odds ratio, 0.56; 95% confidence interval, 0.32 to 0.98) and actual (odds ratio, 0.34; 95% confidence interval, 0.13 to 0.88) cesarean delivery.
CONCLUSION
Cesarean delivery should be the mode of delivery for preterm ≤32 weeks of gestation breech births due to the higher mortality in preterm infants born via vaginal delivery.

Meta-Analysis Review
PURPOSE
This study was aimed to systematically evaluate the efficacy of artificial cycle-prepared frozen-thawed embryo transfer (FET) with or without gonadotrophin-releasing hormone agonist (GnRH-a) pretreatment for women with polycystic ovary syndrome (PCOS).
METHODS
The analysis was carried out by searching the PubMed, EMBASE, and CNKI databases with a combination of keywords before October 2021. The available studies of the effects of GnRH-a pretreatment or no pretreatment on FET in PCOS patients were considered. The risk ratios (RRs) or standardized mean differences (SMD) with 95% confidence intervals (CIs) were calculated with using subgroups and sensitivity analysis. The quality evaluation for this analysis was followed.
RESULTS
Seventeen studies including 3646 women were analyzed. GnRH-a pretreatment was significantly associated with a higher implantation rate (RR = 1.12, 95%CI: 1.00-1.24) and clinical pregnancy rate (RR = 1.19, 95%CI: 1.08-1.32) than the placebo. Moreover, in the GnRH-a pretreatment group, significant differences were detected for increasing the endometrium thickness among PCOS patients (SMD = 0.56, 95%CI: 0.20-0.92). However, for RCTs subgroup, no differences were observed, even after sensitivity analyses. In addition, the miscarriage rates, ectopic pregnancy rates, multiple pregnancy rates, and live birth rates were similar in both two groups.
CONCLUSIONS
Endometrial preparation using GnRH agonist pretreatment prior to FET seems to be the better choice for PCOS patients. However, well-designed RCTs are required for confirmation.

Review
BACKGROUND
Early identification of psychosocial vulnerability among expectant parents through psychosocial assessment is increasingly recommended within maternity care. For routine antenatal assessment, a strong recognition exists regarding conversational assessment tools. However, the knowledge base of conversational tools is limited, inhibiting their clinical use.
OBJECTIVE
Synthesising existing knowledge pertaining to antenatal conversational psychosocial assessment tools, including identifying characteristics, acceptability, performance, effectiveness and unintended consequences.
DESIGN
Mixed-method systematic review based on searches in CINAHL, PubMed, Embase, PsycINFO, Cochrane and Scopus. 20 out of 5394 studies were included and synthesised with a convergent integrated approach using a thematic analysis strategy.
FINDINGS
We identified seven antenatal psychosocial assessment tools that partially or completely utilised a conversational approach. Women's acceptability was high, and tools were generally found to support person-centred communication and the parent-health care professional relationship. Evidence regarding effectiveness and performance of conversational tools was limited. Unintended consequences were found, including some women having negative experiences related to assessment of intimate partner violence, lack of preparation and lack of relevance. High acceptability was reported by health care professionals who considered the tools as valuable and enhancing of identification of vulnerability. Unintended consequences, including lack of time and competencies as well as discomfort when assessment is very sensitive, were reported.
CONCLUSIONS
Evidence regarding conversational tools' effectiveness and performance is limited. More is known about the acceptability of conversational tools, which is generally highly acceptable among women and health care professionals. Some unintended consequences of the use of included conversational tools were identified.

Meta-Analysis
BACKGROUND
Sudden sensorineural hearing loss (SSNHL) during pregnancy is a rare condition and has not been much studied. The study aimed to perform a systematic review and meta-analysis of the risk factors, complications, and treatment modalities for SSNHL in pregnant women.
MATERIALS AND METHODS
PubMed, Web of Science, Scopus, ProQuest, and Google Scholar were used for the literature search. The Cochrane technique for assessing risk of bias was used for the article quality appraisal, and RevMan 5.4 was used for conducting the meta-analysis. Standard mean difference (SMD) and odds ratios with a 95% confidence interval (95% CI) were utilized. Heterogeneity and publication bias were assessed using the I-square (I2) test statistic and the Egger's test, respectively.
RESULTS AND DISCUSSION
The seven primary studies employed prospective and retrospective study designs. The meta-analysis showed that there were fewer risk variables for SSNHL in the experimental group compared with those in the control group (SMD = -0.45 to 3.24, 95% CI = -3.063.63 to 2.16-2.85), indicating that the analysis revealed an insignificant difference. However, the treated patients presented hearing improvement, suggesting a significant analysis (SMD = -0.6710.20, 95% CI = -1.2713.51 to -0.066.88). Furthermore, after therapy, substantial differences were observed in SMD between the two groups (SMD = -0.7415.18, 95% CI = -1.2423.85 to -0.256.40) in favor of the experimental group patients, based on the analysis results of four included studies. However, the I2-value of 0% showed that the heterogeneity was low.
CONCLUSION
SSNHL during pregnancy is a notably rare condition with an unknown cause. However, hormonal fluctuations, particularly increased levels of estrogen and progesterone during pregnancy, have been frequently implicated as potential triggers for SSNHL.

Review
Microplastic (MP) pollution is a growing global concern because of its potential to impair human health, particularly with regard to fetal development. However, the origins of prenatal MP exposure and its effects on fetal development have not been well studied. This study aimed to provide a systematic review of the literature regarding the impact of microplastics on pregnancy and fetal development. PubMed, Embase, ScienceDirect, Web of Science, Scopus, and Google Scholar were searched from 2010 until March 2024. Original publications exploring the impact of microplastics on pregnancy and fetal development were included in the study. After selecting papers, two independent reviewers extracted data regarding study characteristics, microplastics identified, and reproductive impacts. The quality of studies was assessed using the Critical Appraisal Checklists for Studies created by the Joanna Briggs Institute (JBI). Twelve studies, including 234 subjects, were selected from a total of 2,809 citations for the final qualitative analysis. Articles were published between 2021 and 2024, and most were conducted in China. The results of the included studies confirmed the existence of microplastics with varying sizes (2.1 to 100 micrometers) in the placenta and the fetal body. Studies revealed correlations between lifestyle choices and the presence of microplastics in the placenta. They also reported correlations between the level of microplastics and diminished microbiome diversity, reduced birthweights, affected gestational age, and fetal growth and development. Microplastics may be detrimental to a developing fetus during pregnancy. Nonetheless, more thorough research is required to comprehend the impact of microplastic exposure on pregnancy and fetal development.

Meta-Analysis
BACKGROUND
Acute HIV infection during pregnancy and in the postpartum period increases the risk of vertical transmission. The World Health Organization (WHO) has recommended preexposure prophylaxis for pregnant and postpartum women at risk of acquiring HIV. However, there are significant gaps between the actual practice and the ideal goal of preexposure prophylaxis implementation among pregnant and postpartum women. Therefore, it is important to determine what influences women's implementation of preexposure prophylaxis during pregnancy and in the postpartum period. This review aims to aggregate barriers and facilitators to preexposure prophylaxis implementation among pregnant and postpartum women.
METHODS
A range of electronic databases, including PubMed, CINAHL Plus with Full Text, Embase, and Web of Science, were searched for potentially relevant qualitative studies. The search period extended from the establishment of the databases to March 16, 2023. This review used the ENTREQ (Enhancing transparency in reporting of qualitative research synthesis) statement to guide the design and reporting of qualitative synthesis. The methodological quality of the included studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. The JBI meta-aggregation method was applied for guiding the data extraction, and the JBI ConQual method was applied for guiding the evaluation of the level of evidence for the synthesis.
RESULTS
Of retrieved 2042 studies, 12 met the inclusion criteria. The total population sample included 447 participants, including 231 pregnant and postpartum women, 21 male partners, 75 healthcare providers (HCPs)/healthcare workers (HCWs), 18 policymakers, 37 mothers, and 65 women of childbearing age. A total of 149 findings with credibility ratings of "unequivocal" or "equivocal" were included in this meta-synthesis. Barriers and facilitators to preexposure prophylaxis implementation were coded into seven categories, including three facilitator categories: perceived benefits, maintaining relationships with partners, and external support, and four barriers: medication-related barriers, stigma, barriers at the level of providers and facilities, and biases in risk perception.
CONCLUSION
This systematic review and meta-synthesis aggregated the barriers and facilitators of preexposure prophylaxis implementation among pregnant and postpartum women. We aggregated several barriers to maternal preexposure prophylaxis implementation, including medication-related factors, stigma, barriers at the level of providers and facilities, and risk perception biases. Therefore, intervention measures for improving preexposure prophylaxis services can be developed based on these points.

INTRODUCTION
Smoking during pregnancy is harmful to maternal and child health. Vaping is used for smoking cessation but evidence on health effects during pregnancy is scarce. We conducted a systematic review of health outcomes of vaping during pregnancy.
METHODS
We searched six databases for maternal/fetal/infant outcomes and vaping, including quantitative, English language, human studies of vaping during pregnancy, to November 10th, 2023. We assessed study quality with the Mixed-Methods Appraisal Tool. We focused on comparisons of exclusive-vaping with non-use of nicotine and tobacco products and with smoking. Presentation is narrative as the studies were of insufficient quality to conduct meta-analysis.
RESULTS
We included 26 studies, with 765,527 women, with one randomised controlled trial (RCT) comparing vaping and nicotine replacement therapy for smoking cessation, 23 cohort studies and two case-control studies. While the RCT met 4/5 quality criteria, the quality of the cohort studies and case-control studies was poor; none adequately assessed exposure to smoking and vaping. For studies comparing exclusive-vaping with 'non-use', more reported no increased risk for vaping (three studies) than reported increased risk for maternal pregnancy/postpartum outcomes (one study) and for fetal and infant outcomes (20 studies no increased risk, four increased risk), except for birth-weight and neurological outcomes where two studies each observed increased and no increased risk. When the RCT compared non-users with those not smoking but vaping or using NRT, irrespective of randomisation, they reported no evidence of risk for vaping/NRT. For studies comparing exclusive-vaping and exclusive-smoking, most studies provided evidence for a comparable risk for different outcomes. One maternal biomarker study revealed a lower risk for vaping. For small-for-gestational-age/mean-birth-centile equal numbers of studies found lower risk for vaping than for smoking as found similar risk for the two groups (two each).
CONCLUSIONS
While more studies found no evidence of increased risk of exclusive-vaping compared with non-use and evidence of comparable risk for exclusive-vaping and exclusive-smoking, the quality of the evidence limits conclusions. Without adequate assessment of exposure to vaping and smoking, findings cannot be attributed to behaviour as many who vape will have smoked and many who vape may do so at low levels.

Review
Literature surrounding miscarriage is broad in scope, yet narrative constructions following miscarriage are significantly under-researched. Few studies have sought to understand sense-making processes following miscarriage, including how and why people story their experience. Consequently, the complexities and nuances of these processes have not been adequately explored. This review aimed to gain insight into what is already known about how people story their experience of miscarriage, as well as research gaps and limitations. A systematic literature review of qualitative literature was conducted across four databases to identify relevant research related to miscarriage narratives and sense-making. Eligibility criteria was applied to a staged screening process to identify the highest quality, peer-reviewed research. Ten studies were included in the review and presented as a narrative synthesis. The literature was divided into five collective themes: women's perspectives, male partner's perspectives, couples' perspectives, healthcare professional's perspectives, and cultural perspectives. The literature review summarises existing knowledge about narrative processes in relation to miscarriage, as well as highlighting research gaps, clinical implications, and directions for future research. When working with those who have experienced involuntary child loss and infertility, there is a need for professionals to have appropriate training to support the provision of compassionate, individualised care and decision-making. The role of language requires consideration as there is a need to address over-medicalised systems of knowledge, and it is important that there is understanding regarding the need for expression, and the various ways that individuals might express their feelings and loss.

Meta-Analysis
The etiology of recurrent pregnancy loss (RPL) is complex and multifactorial and in half of patients it remains unexplained (U-RPL). Recently, low-molecular-weight heparin (LMWH) has gained increasing relevance for its therapeutic potential. On this regard, the aim of this systematic review and meta-analysis is to analyze the efficacy of low molecular weight heparin (LMWH) from the beginning of pregnancy in terms of live birth rates (LBR) in U-RPL. Registered randomized controlled trials (RCTs) were included. We stratified findings based on relevant clinical factors including number of previous miscarriages, treatment type and control type. Intervention or exposure was defined as the administration of LMWH alone or in combination with low-dose aspirin (LDA). A total of 6 studies involving 1016 patients were included. The meta-analysis results showed that LMWH used in the treatment of U-RPL was not associated with an increase in LBR with a pooled OR of 1.01, a medium heterogeneity (26.42%) and no publication bias. Results of other sub-analyses according to country, treatment type, and control type showed no significant effect of LMWH on LBR in all subgroups, with a high heterogeneity. The results highlight a non-significant effect of LMWH in U-RPL on LBR based on moderate quality evidence.Registration number: PROSPERO: ( https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022326433 ).
