Genitourinary infection and gastroschisis: A systematic review and meta-analysis.

BACKGROUND: Gastroschisis is a congenital anomaly of the umbilical ring with increasing prevalence, especially amongst younger mothers. There is increasing evidence that exposure to genitourinary infections (GUTI) may play an important role in the etiology of gastroschisis. This systematic review and meta-analysis aimed to identify, appraise, and summarize the literature on exposure to GUTI and gastroschisis. METHODS: Six electronic databases (MEDLINE, EMBASE, Web of Science, Scopus, Cochrane Library electronic databases, and Prospero) were searched using a comprehensive search strategy. Citations and cited articles for all included studies were searched. Peer-reviewed, quantitative studies reporting an association of urinary tract infections (UTI) and/or sexually transmitted infections (STI) with gastroschisis were included. Prospero registration CRD42022377420. RESULTS: A total of 2392 papers were identified via the searches of which 15 met our inclusion criteria and were included after title and abstract and full text screening. The study period for included studies ranged from 1995 to 2016, most were from the USA. Four studies considering exposure to STIs and five to UTIs were eligible to progress to meta-analysis. Meta-analysis identified a significantly increased risk of gastroschisis in association with periconceptional exposure to UTI [OR 1.54 (95% CI 1.29, 1.8)], STI [OR 1.4 (95% CI 1.01, 1.79)]. CONCLUSIONS: Periconceptional exposure to GUTI is associated with an increased risk of gastroschisis. The prevention and timely treatment of GUTI amongst women of childbearing age may help to reduce the occurrence of gastroschisis.

Healthcare professional perspectives on improving inter-pregnancy care after a baby loss for women with type 1 and type 2 diabetes.

AIMS: Women with diabetes (WWD) (type 1 and type 2) are around four times more likely to experience baby loss: miscarriage, stillbirth, neonatal death or termination of pregnancy for medical reasons. Many WWD become pregnant again soon after loss. This study aimed to explore healthcare professional perspectives on improving inter-pregnancy care for WWD after baby loss, as they play a crucial role in facilitating access to support for WWD to prepare for subsequent pregnancy. METHODS: Eighteen healthcare professionals recruited through social media and professional networks between November 2020 and July 2021 participated in a semi-structured remote interview. Data were analysed using thematic analysis. RESULTS: Three main themes were identified: (1) supporting WWD who want to become pregnant again after baby loss; (2) recognising multiple hidden burdens in the inter-pregnancy interval after loss; (3) discontinuities and constraints in inter-pregnancy care. Most participants tended to assume WWD wanted time and space before thinking about pregnancy after loss, so they did not routinely broach the subject. Participants reported receiving little or no training on managing sensitive conversations. Care provision varied across providers, and unclear referral pathways were challenging to navigate. Participants reported concerns that not all healthcare professionals knew how to mitigate pregnancy risks. CONCLUSIONS: It is unclear who is responsible for supporting WWDs preconception health between baby loss and subsequent pregnancy. Healthcare professionals may be reticent to initiate conversations about pregnancy for fear of causing upset or distress. Future research is required to scope out ways to raise awareness among healthcare professionals and practical tips on sensitively raising the topic of subsequent pregnancy.

The effects of radiofrequency exposure on male fertility: A systematic review of human observational studies with dose-response meta-analysis.

BACKGROUND: The World Health Organization (WHO) is bringing together evidence on radiofrequency electromagnetic field (RF-EMF) exposure in relation to health outcomes, previously identified as priorities for research and evaluation by experts in the field, to inform exposure guidelines. A suite of systematic reviews have been undertaken by a network of topic experts and methodologists to collect, assess and synthesise data relevant to these guidelines. Following the WHO handbook for guideline development and the COSTER conduct guidelines, we systematically reviewed the evidence on the potential effects of RF-EMF exposure on male fertility in human observational studies. METHODS: We conducted a broad and sensitive search for potentially relevant records within the following bibliographic databases: MEDLINE; Embase; Web of Science and EMF Portal. We also conducted searches of grey literature through relevant databases including OpenGrey, and organisational websites and consulted RF-EMF experts. We hand searched reference lists of included study records and for citations of these studies. We included quantitative human observational studies on the effect of RF-EMF exposure in adult male participants on infertility: sperm concentration; sperm morphology; sperm total motility; sperm progressive motility; total sperm count; and time to pregnancy. Titles and abstracts followed by full texts were screened in blinded duplicate against pre-set eligibility criteria with consensus input from a third reviewer as required. Data extraction from included studies was completed by two reviewers, as was risk of bias assessment using the Office of Health Assessment and Translation (OHAT) tool. We conducted a dose-response meta-analysis as possible and appropriate. Certainty of the evidence was assessed by two reviewers using the OHAT GRADE tool with input from a third reviewer as required. RESULTS: We identified nine studies in this review; seven were general public studies (with the general public as the population of interest) and two were occupational studies (with specific workers/workforces as the population of interest). General public studies. Duration of phone use: The evidence is very uncertain surrounding the effects of RF-EMF on sperm concentration (10/6 mL) (MD (mean difference) per hour of daily phone use 1.6 106/mL, 95 % CI -1.7 to 4.9; 3 studies), sperm morphology (MD 0.15 percentage points of deviation of normal forms per hour, 95 % CI -0.21 to 0.51; 3 studies), sperm progressive motility (MD -0.46 percentage points per hour, 95 % CI -1.04 to 0.13; 2 studies) and total sperm count (MD per hour -0.44 106/ejaculate, 95 % CI -2.59 to 1.7; 2 studies) due to very low-certainty evidence. Four additional studies reported on the effect of mobile phone use on sperm motility but were unsuitable for pooling; only one of these studies identified a statistically significant effect. All four studies were at risk of exposure characterisation and selection bias; two of confounding, selective reporting and attrition bias; three of outcome assessment bias and one used an inappropriate statistical method. Position of phone: There may be no or little effect of carrying a mobile phone in the front pocket on sperm concentration, total count, morphology, progressive motility or on time to pregnancy. Of three studies reporting on the effect of mobile phone location on sperm total motility and, or, total motile count, one showed a statistically significant effect. All three studies were at risk of exposure characterisation and selection bias; two of confounding, selective reporting and attrition bias; three of outcome assessment bias and one used inappropriate statistical method. RF-EMF Source: One study indicates there may be little or no effect of computer or other electric device use on sperm concentration, total motility or total count. This study is at probably high risk of exposure characterisation bias and outcome assessment bias. Occupational studies. With only two studies of occupational exposure to RF-EMF and heterogeneity in the population and exposure source (technicians exposed to microwaves or seamen exposed to radar equipment), it was not plausible to statistically pool findings. One study was at probably or definitely high risk of bias across all domains, the other across domains for exposure characterisation bias, outcome assessment bias and confounding. DISCUSSION: The majority of evidence identified was assessing localised RF-EMF exposure from mobile phone use on male fertility with few studies assessing the impact of phone position. Overall, the evidence identified is very uncertain about the effect of RF-EMF exposure from mobile phones on sperm outcomes. One study assessed the impact of other RF-EMF sources on male fertility amongst the general public and two studies assessed the impact of RF-EMF exposure in occupational cohorts from different sources (radar or microwave) on male fertility. Further prospective studies conducted with greater rigour (in particular, improved accuracy of exposure measurement and appropriate statistical method use) would build the existing evidence base and are required to have greater certainty in any potential effects of RF-EMF on male reproductive outcomes.

The effects of radiofrequency exposure on adverse female reproductive outcomes: A systematic review of human observational studies with dose-response meta-analysis.

BACKGROUND: To inform radiofrequency electromagnetic field (RF-EMF) exposure guidelines the World Health Organization (WHO) is bringing together evidence on RF-EMF in relation to health outcomes prioritised for evaluation by experts in this field. Given this, a network of topic experts and methodologists have conducted a series of systematic reviews collecting, assessing, and synthesising data of relevance to these guidelines. Here we present a systematic review of the effect of RF-EMF exposure on adverse pregnancy outcomes in human observational studies which follows the WHO handbook for guideline development and the COSTER conduct guidelines. METHODS: We conducted a broad, sensitive search for potentially relevant records within the following bibliographic databases: MEDLINE; Embase; and the EMF Portal. Grey literature searches were also conducted through relevant databases (including OpenGrey), organisational websites and via consultation of RF-EMF experts. We included quantitative human observational studies on the effect of RF-EMF exposure in adults' preconception or pregnant women on pre-term birth, small for gestational age (SGA; associated with intrauterine growth restriction), miscarriage, stillbirth, low birth weight (LBW) and congenital anomalies. In blinded duplicate, titles and abstracts then full texts were screened against eligibility criteria. A third reviewer gave input when consensus was not reached. Citation chaining of included studies was completed. Two reviewers' data extracted and assessed included studies for risk of bias using the Office of Health Assessment and Translation (OHAT) tool. Random effects meta-analyses of the highest versus the lowest exposures and dose-response meta-analysis were conducted as appropriate and plausible. Two reviewers assessed the certainty in each body of evidence using the OHAT GRADE tool. RESULTS: We identified 18 studies in this review; eight were general public studies (with the general public as the population of interest) and 10 were occupational studies (with the population of interest specific workers/workforces). General public studies. From pairwise meta-analyses of general public studies, the evidence is very uncertain about the effects of RF-EMF from mobile phone exposure on preterm birth risk (relative risk (RR) 1.14, 95% confidence interval (CI): 0.97-1.34, 95% prediction interval (PI): 0.83-1.57; 4 studies), LBW (RR 1.14, 95% CI: 0.96-1.36, 95% PI: 0.84-1.57; 4 studies) or SGA (RR 1.13, 95% CI: 1.02-1.24, 95% PI: 0.99-1.28; 2 studies) due to very low-certainty evidence. It was not feasible to meta-analyse studies reporting on the effect of RF-EMF from mobile phone exposure on congenital anomalies or miscarriage risk. The reported effects from the studies assessing these outcomes varied and the studies were at some risk of bias. No studies of the general public assessed the impact of RF-EMF exposure on stillbirth. Occupational studies. In occupational studies, based on dose-response meta-analyses, the evidence is very uncertain about the effects of RF-EMF amongst female physiotherapists using shortwave diathermy on miscarriage due to very low-certainty evidence (OR 1.02 95% CI 0.94-1.1; 2 studies). Amongst offspring of female physiotherapists using shortwave diathermy, the evidence is very uncertain about the effects of RF-EMF on the risk of congenital malformations due to very low-certainty evidence (OR 1.4, 95% CI 0.85 to 2.32; 2 studies). From pairwise meta-analyses, the evidence is very uncertain about the effects of RF-EMF on the risk of miscarriage (RR 1.06, 95% CI 0.96 to 1.18; very low-certainty evidence), pre-term births (RR 1.19, 95% CI 0.32 to 4.37; 3 studies; very low-certainty evidence), and low birth weight (RR 2.90, 95% CI: 0.69 to 12.23; 3 studies; very low-certainty evidence). Results for stillbirth and SGA could not be pooled in meta-analyses. The results from the studies reporting these outcomes were inconsistent and the studies were at some risk of bias. DISCUSSION: Most of the evidence identified in this review was from general public studies assessing localised RF-EMF exposure from mobile phone use on female reproductive outcomes. In occupational settings, each study was of heterogenous whole-body RF-EMF exposure from radar, short or microwave diathermy, surveillance and welding equipment and its effect on female reproductive outcomes. Overall, the body of evidence is very uncertain about the effect of RF-EMF exposure on female reproductive outcomes. Further prospective studies conducted with greater rigour (particularly improved accuracy of exposure measurement and using appropriate statistical methods) are required to identify any potential effects of RF-EMF exposure on female reproductive outcomes of interest.

Barriers and facilitators of adherence to low-dose aspirin during pregnancy: A co-produced systematic review and COM-B framework synthesis of qualitative evidence.

INTRODUCTION: Women at increased risk of developing pre-eclampsia are advised to take a daily low-dose of aspirin from 12 weeks of pregnancy to reduce their risks. Despite the well-established prophylactic effect of aspirin, adherence to this therapy is low. This systematic review aimed to summarise evidence on the barriers and facilitators of adherence to low-dose aspirin to inform intervention development to support decision making and persistence with aspirin use for pre-eclampsia prevention. MATERIALS AND METHODS: A systematic review and meta-synthesis of qualitative research was co-produced by representatives from charities, and public, clinical and academic members. Eight electronic databases (MEDLINE, PsycINFO, CINAHL, Web of Science, Scopus, EMBASE, Prospero, OpenGrey), archives of charities and professional organisations were searched (between October and November 2023 and re-run in August 2023) using predefined search terms. Studies containing qualitative components related to barriers and facilitators of adherence to low-dose aspirin during pregnancy were included. Quality assessment was performed using the Critical Appraisal Skills Programme checklist for qualitative research. A combination of the COM-B framework with phases of adherence process as defined by international taxonomy was used as the coding framework. Co-production activities were facilitated by use of 'Zoom' and 'Linoit'. RESULTS: From a total of 3377 papers identified through our searches, five published studies and one dissertation met our inclusion criteria. Studies were published from 2019 to 2022 covering research conducted in the USA, Canada, UK, Netherlands and Australia. Barriers and facilitators to adherence were mapped to six categories of the COM-B for three phases of adherence: initiation, implementation, and discontinuation. The discontinuation phase of adherence was only mentioned by one author. Four key themes were identified relating to pregnancy: 'Insufficient knowledge', 'Necessity concerns balance', 'Access to medicine', 'Social influences', and 'Lack of Habit'. CONCLUSIONS: The COM-B framework allowed for detailed mapping of key factors shaping different phases of adherence in behavioural change terms and now provides a solid foundation for the development of a behavioural intervention. Although potential intervention elements could be suggested based on the results of this synthesis, additional co-production work is needed to define elements and plan for the delivery of the future intervention.

Demographic and pregnancy-related predictors of postnatal contraception uptake: A cross-sectional study.

OBJECTIVE: To examine the uptake of postnatal contraception (PNC) and experiences of PNC care across a geographical region of England. DESIGN: Cross-sectional online survey. SETTING: The North East and North Cumbria Integrated Care System (ICS). POPULATION: Women who had completed a pregnancy in the previous 3 years. METHODS: The uptake of PNC by accessed method(s) and the availability of preferred method(s) is described, and adjusted odds ratios are reported for group differences in uptake by characteristics of interest. MAIN OUTCOME MEASURES: Uptake of medically prescribed/administered contraception and uptake of long-acting reversible contraception (LARC) during the postnatal period, and access to preferred PNC methods. RESULTS: Although almost half of respondents (47.1%; n = 1178) reinitiated some form of sexual activity during the postnatal period, only 38.7% (n = 969) of respondents accessed a medically prescribed/administered contraceptive method postnatally, and only 15.5% (n = 389) of respondents accessed a LARC. It is a matter of concern that 18.8% (n = 451) of respondents indicated that they were unable to access their preferred PNC. In multivariate analysis, younger age, lower household income, higher multiparity, operative delivery, unplanned pregnancy and not breastfeeding were significant predictors of higher PNC uptake. CONCLUSIONS: The uptake of PNC in this cohort was low, with almost a fifth of women unable to access their preferred method. However, there was some evidence that women belonging to groups perceived to be at risk of rapid repeat pregnancy were more likely to access reliable PNC methods.

Poverty proofing healthcare: A qualitative study of barriers to accessing healthcare for low-income families with children in northern England.

Poverty impacts negatively on children's health and future life chances. Access to the UK's National Health Service (NHS) is based on clinical need rather than the ability to pay but horizontal inequities in access exist. Children North East, a charity supporting children experiencing poverty, are working with partners to reduce the impacts of poverty on NHS access. This collaborative study aimed to understand barriers to healthcare access faced by families living on low incomes to validate and support further development of a Poverty Proofing© healthcare tool. Twenty-four parents and eight Voluntary Community Social Enterprise sector staff participated in qualitative interviews or focus groups. Data were analysed thematically, and three main themes were identified as impacting access to healthcare: hidden costs, securing appointments and developing relationships with healthcare providers. We conclude that low-income families experience both financial and other barriers to accessing NHS healthcare and that these barriers are exacerbated for low-income families living in remote/rural areas.

The Gestational Obesity Weight Management: Implementation of National Guidelines (GLOWING) study: a pilot cluster randomised controlled trial.

BACKGROUND: Pregnancy weight management interventions can improve maternal diet, physical activity, gestational weight gain, and postnatal weight retention. UK guidelines were published in 2010 but health professionals report multiple complex barriers to practice. GLOWING used social cognitive theory to address evidence-based barriers to midwives' implementation of weight management guidelines into routine practice. This paper reports the pilot trial outcomes relating to feasibility and acceptability of intervention delivery and trial procedures. METHODS: GLOWING was a multi-centre parallel-group pilot cluster RCT comparing the delivery of a behaviour change intervention for midwives (delivered as training workshops) with usual practice. The clusters were four NHS Trusts in Northeast England, randomised to intervention or control arms. Blinding of allocation was not possible due to the nature of the intervention. We aimed to deliver the intervention to all eligible midwives in the intervention arm, in groups of 6 midwives per workshop, and to pilot questionnaire data collection for a future definitive trial. Intervention arm midwives' acceptability of GLOWING content and delivery was assessed using a mixed methods questionnaire, and pregnant women's acceptability of trial procedures by interviews. Quantitative data were analysed descriptively and qualitative data thematically. RESULTS: In intervention arm Trusts, 100% of eligible midwives (n = 67) were recruited to, and received, the intervention; however, not all workshops had the planned number of attendees (range 3-8). The consent rate amongst midwives randomised (n = 100) to complete questionnaires was 74% (n = 74) (95% CI 65%, 83%), and overall completion rate 89% (n = 66) (95% CI 82%, 96%). Follow-up response rate was 66% (n = 49) (95% CI 55%, 77%), with a marked difference between intervention (39%, n = 15) and control (94%, n = 34) groups potentially due to the volume of research activities. Overall, 64% (n = 47) (95% CI 53%, 75%) completed both baseline and follow-up questionnaires. Midwives viewed the intervention as acceptable and directly relevant to routine practice. The least popular components related to scripted role-plays. Pregnant women viewed the recruitment and trial processes to be acceptable. CONCLUSIONS: This rigorously conducted pilot study demonstrated feasibility intervention delivery and a high level of acceptability amongst participants. It has provided information required to refine the intervention and trial protocol, enhancing confidence that a definitive trial could be carried out.

Academic achievement at ages 11 and 16 in children born with congenital anomalies in England: A multi-registry linked cohort study.

BACKGROUND: Children born with major congenital anomalies (CAs) have lower academic achievement compared with their peers, but the existing evidence is restricted to a number of specific CAs. OBJECTIVES: To investigate academic outcomes at ages 11 and 16 in children with major isolated structural CAs and children with Down or Turner syndromes. METHODS: This population-based cohort study linked data on approximately 11,000 school-aged children born with major CAs in 1994-2004 registered by four regional CA registries in England with education data from the National Pupil Database (NPD). The comparison group was a random sample of children without major CAs from the background population recorded in the NPD that were frequency matched (5:1) to children with CAs by birth year, sex and geographical area. RESULTS: Overall, 71.9%, 73.0% and 80.9% of children with isolated structural CAs achieved the expected attainment level at age 11 compared to 78.3%, 80.6% and 86.7% of the comparison group in English language, Mathematics and Science, respectively. Children with nervous system CAs as a whole had the lowest proportion who achieved the expected attainment at age 11. At age 16, 46.9% of children with CAs achieved the expected level compared to 52.5% of their peers. Major CAs were associated with being up to 9% (95% confidence interval [CI] 8%, 11%) and 12% (95% CI 9%, 14%) less likely to achieve expected levels at ages 11 and 16, respectively, after adjustment for socioeconomic deprivation. CONCLUSIONS: Although many children with isolated CAs achieved the expected academic level at ages 11 and 16, they were at higher risk of underachievement compared to their peers. These stark yet cautiously encouraging results are important for counselling parents of children with specific CAs and also highlight the possible need for special education support to reduce potential academic difficulties.

Predictors of Post-Operative Hospital Length of Stay Following Complete Repair of Tetralogy of Fallot in a Pediatric Cohort in the North of England.

We sought to estimate the median post-operative length of stay (PLOS) and predictors of PLOS following tetralogy of Fallot (ToF) repair at a specialist surgical center in the North of England. The local National Congenital Heart Disease Audit dataset was used to identify patients aged < 2 years who underwent surgical repair for ToF between 1 January 1986 and 13 May 2022. Coefficients representing the median change in PLOS (days) according to predictors were estimated using Quantile regression. There were 224 patients (59.4% male, median age = 9 months, interquartile range (IQR) 5-13 months) with a median PLOS of 9 days (IQR 7-13). In the univariable regression, age (months) and weight (kg) at operation (ß = - 0.17, 95% CI: - 0.33, - 0.01) and (ß = - 0.53, 95% CI: - 0.97, - 0.10), previous (cardiac or thoracic) procedure (ß = 5, 95% CI:2.38, 7.62), procedure urgency (elective vs urgent) (ß = 2.8, 95% CI:0.39, 5.21), bypass time (mins) (ß = 0.03, 95% CI:0.01, 0.05), cross-clamp time (mins) (ß = 0.03, 95% CI:0.01, 0.06) and duration of post-operative intubation (days) (ß = 0.81, 95% CI:0.67, 0.96), were significantly associated with PLOS. Previous procedure and intubation time remained significant in multivariable analyses. Some patient and operative factors can predict PLOS following complete ToF repair. Information on PLOS is important for health professionals to support parents in preparing for their child's discharge and to make any necessary practical arrangements. Health commissioners can draw on evidence-based guidance for resource planning. The small sample size may have reduced the power to detect small effect sizes, but this regional study serves as a foundation for a larger national study.

Surveillance of multiple congenital anomalies; searching for new associations.

Many human teratogens are associated with a spectrum of congenital anomalies rather than a single defect, and therefore the identification of congenital anomalies occurring together more frequently than expected may improve the detection of teratogens. Thirty-two EUROCAT congenital anomaly registries covering 6,599,765 births provided 123,566 cases with one or more major congenital anomalies (excluding chromosomal and genetic syndromes) for the birth years 2008-2016. The EUROCAT multiple congenital anomaly algorithm identified 8804 cases with two or more major congenital anomalies in different organ systems, that were not recognized as part of a syndrome or sequence. For each pair of anomalies, the odds of a case having both anomalies relative to having only one anomaly was calculated and the p value was estimated using a two-sided Fisher's exact test. The Benjamini-Hochberg procedure adjusted p values to control the false discovery rate and pairs of anomalies with adjusted p values < 0.05 were identified. A total of 1386 combinations of two anomalies were analyzed. Out of the 31 statistically significant positive associations identified, 20 were found to be known associations or sequences already described in the literature and 11 were considered "potential new associations" by the EUROCAT Coding and Classification Committee. After a review of the literature and a detailed examination of the individual cases with the anomaly pairs, six pairs remained classified as new associations. In summary, systematically searching for congenital anomalies occurring together more frequently than expected using the EUROCAT database is worthwhile and has identified six new associations that merit further investigation.

Contraception prescribing in England during the COVID-19 pandemic.

BACKGROUND: National lockdowns in England due to COVID-19 resulted in rapid shifts in healthcare provision, including in primary care where most contraceptive prescriptions are issued. This study aimed to investigate contraception prescribing trends in primary care during the pandemic and the impact of socioeconomic deprivation. METHODS: Prescribing data were accessed from the English Prescribing Dataset for the first year of the COVID-19 pandemic (1 March 2020-28 February 2021) and the year prior (1 March 2019-29 February 2020). Data were analysed by geographical region (London, Midlands and East of England, North of England, South of England) and contraceptive type (progestogen-only pill (POP), combined oral contraception (COC), emergency hormonal contraception (EHC) and contraceptive injections). Differences in prescribing rates were calculated using Poisson regression. Pearson correlation coefficients were calculated for the Index of Multiple Deprivation (IMD) scores for each Clinical Commissioning Group (CCG) in the North East and North Cumbria (NENC). RESULTS: Contraception prescribing rates decreased overall during the COVID-19 pandemic in England (Poisson regression coefficient (ß)=-0.035), with a statistically significant (p<0.01) decrease in all four regions. Prescriptions decreased for COC (ß=-0.978), contraceptive injections (ß=-0.161) and EHC (ß=-0.2005), while POP (ß=0.050) prescribing rates increased. There was a weak positive correlation between IMD and prescribing rates in NENC (p>0.05). CONCLUSIONS: Contraception provision was impacted by COVID-19 with an overall decrease in prescribing rates. The deprivation results suggest that this may not be a significant contributing factor to this decrease. Further research is recommended to better understand these changes, and to ensure that services respond appropriately to population needs.

A systematic review and meta-analysis of school and cognitive function domains of health-related quality of life measures for children and young adults with congenital heart disease.

BACKGROUND: Research on cognitive and school functioning domains of health-related quality of life (HRQOL) for children and adolescents with congenital heart disease (CHD) presents inconsistencies. OBJECTIVES: To summarize and synthesize data on school and cognitive function domains of HRQOL for children and young people (CYP) with CHD. METHODS: Five electronic databases MEDLINE, Scopus, PsycINFO, EMBASE, ERI, and citations were systematically searched. We included original-research articles reporting the cognitive and school function domains of HRQOL for children and young people with CHD (child and parent reports included). Both fixed and random-effects meta-analyses were performed to estimate pooled mean test scores for cognitive and school function. A total of 34 studies met our inclusion criteria and were synthesized narratively, 17 studies were included in formal meta-analyses. RESULTS: Self-reported cognitive function was lower for children and young people with CHD than healthy controls (SMD -0.28 (-0.42, -0.15)). Parental reports demonstrated similar results to self-reports (SMD -0.54 (-0.91, -0.18)). School function was lower in children and young people with CHD compared with healthy controls in self-reported (SMD -0.30 (-0.48, -0.13)) and parent reported HRQOL (SMD -0.49 (0.64, -0.36)). Self-reported school function domain scores were lower for young (<8 years) (SMD -0.65 (-1.32, 0.03)) and older children (8-18 years) (SMD -0.25 (-0.47, -0.03)) with CHD than their peers. Similarly, parents reported lower school function domain scores for young (<8 years) (SMD -0.68 (-1.29, -0.07)) and older (8-18 years) (SMD -0.46 (-068, -0.25)) children with CHD than typically developing peers. CONCLUSION: Children born with CHD may experience lower cognitive and school function HRQOL scores than healthy controls (self and proxy-report). This is consistent with a subgroup meta-analysis of young (<8 years) and older (8 years old or more) children with CHD reporting lower school function scores compared to controls.

Prevalence of neural tube defects in England prior to the mandatory fortification of non-wholemeal wheat flour with folic acid: a population-based cohort study.

OBJECTIVES: To determine the baseline trends in the total birth prevalence of neural tube defects (NTDs) in England (2000-2019) to enable the impact of folic acid fortification of non-wholemeal wheat flour to be monitored. DESIGN: Population-based, observational study using congenital anomaly (CA) registration data for England curated by the National Congenital Anomaly and Rare Disease Registration Service (NCARDRS). SETTING: Regions of England with active registration in the time period. PARTICIPANTS: Babies that were liveborn or stillborn and pregnancies that resulted in a termination of pregnancy or a late miscarriage (20-23 weeks' gestation) with an NTD. MAIN OUTCOME MEASURES: Total birth prevalence of anencephaly, spina bifida and all NTDs in England. Poisson regression analysis was used to evaluate time trends with regional register as a random effect. The progress of national registration across England was assessed. RESULTS: There were 4541 NTD pregnancies out of 3 637 842 births in England; 1982 anencephaly and 2127 spina bifida. NTD prevalence was 12.5 (95% CI 12.1 to 12.9) per 10 000 total births. NTD prevalence per 10 000 total births was significantly higher in 2015-2019 (13.6, 95% CI 12.9 to 14.4) compared with 2010-2014 (12.1, 95% CI 11.7 to 12.5). An increasing trend in NTDs overall was detected (incidence rate ratio (IRR) 1.01, 1.00 to 1.02), although further analysis determined this effect was confined to 2015-2019 (compared against 2000-2004, IRR 1.14, 1.04 to 1.24). The birth prevalence of anencephaly reflected this pattern. The prevalence of spina bifida remained relatively stable over time. CONCLUSIONS: Baseline NTD prevalence for England has been established. National and standardised CA registration is in place, facilitating the systematic and consistent monitoring of pre-fortification and post-fortification NTD trends and evaluating the impact of fortification on NTD prevalence.

Identifying, synthesising and appraising existing evidence relating to myalgic encephalomyelitis/chronic fatigue syndrome and pregnancy: a mixed-methods systematic review.

OBJECTIVES: To identify, synthesise and appraise evidence relating to myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and pregnancy. DESIGN: Mixed-methods systematic review, using convergent segregated design. DATA SOURCES: MEDLINE, EMBASE, Scopus, PsycINFO, CINAHL, MedRxiv, PROSPERO and grey literature sources through 6 August 2023. ELIGIBILITY CRITERIA: We included original research studies, expert opinion and grey literature reporting on ME/CFS and pregnancy/post partum (up to 2 years), risk of pregnancy outcomes with ME/CFS or experiences during pregnancy for mother, partner or health and social care professionals following ME/CFS during pregnancy, all where the evidence was relevant to a confirmed ME/CFS diagnosis prior to pregnancy. DATA EXTRACTION AND SYNTHESIS: Three independent reviewers completed all screening, data extraction and quality assessment. Risk of bias was assessed using the mixed-methods appraisal tool V.2018. Qualitative and quantitative literature was analysed separately using thematic and descriptive syntheses. Findings were integrated through configuration. RESULTS: Searches identified 3675 articles, 16 met the inclusion criteria: 4 quantitative (1 grey), 11 qualitative (9 grey) and 1 grey mixed-methods study. Of the four quantitative studies that reported on ME/CFS severity during pregnancy, two suggested pregnancy negatively impacted on ME/CFS, one found most women had no change in ME/CFS symptoms and one found ME/CFS improved; this difference in symptom severity across studies was supported by the qualitative evidence. The qualitative literature also highlighted the importance of individualised care throughout pregnancy and birth, and the need for additional support during family planning, pregnancy and with childcare. Only one quantitative study reported on pregnancy outcomes, finding decreased vaginal births and higher rates of spontaneous abortions and developmental and learning delays associated with pregnancies in those with ME/CFS. CONCLUSIONS: Current evidence on ME/CFS in pregnancy is limited and findings inconclusive. More high-quality research is urgently needed to support the development of evidence-based guidelines on ME/CFS and pregnancy.

Influence of neighborhood-level socioeconomic deprivation and individual socioeconomic position on risk of developing type 2 diabetes in older men: a longitudinal analysis in the British Regional Heart Study cohort.

INTRODUCTION: Evidence from longitudinal studies on the influence of neighborhood socioeconomic deprivation in older age on the development of type 2 diabetes mellitus (T2DM) is limited. This study investigates the prospective associations of neighborhood-level deprivation and individual socioeconomic position (SEP) with T2DM incidence in older age. RESEARCH DESIGN AND METHODS: The British Regional Heart Study studied 4252 men aged 60-79 years in 1998-2000. Neighborhood-level deprivation was based on the Index of Multiple Deprivation quintiles for participants' 1998-2000 residential postcode. Individual SEP was defined as social class based on longest-held occupation. A cumulative score of individual socioeconomic factors was derived. Incident T2DM cases were ascertained from primary care records; prevalent cases were excluded. Cox proportional hazard models were used to examine the associations. RESULTS: Among 3706 men, 368 incident cases of T2DM were observed over 18 years. The age-adjusted T2DM risk increased from the least deprived quintile to the most deprived: HR per quintile increase 1.14 (95% CI 1.06 to 1.23) (p=0.0005). The age-adjusted T2DM HR in social class V (lowest) versus social class I (highest) was 2.45 (95% CI 1.36 to 4.42) (p=0.001). Both associations attenuated but remained significant on adjustment for other deprivation measures, becoming non-significant on adjustment for body mass index and T2DM family history. T2DM risk increased with cumulative individual adverse socioeconomic factors: HR per point increase 1.14 (95% CI 1.05 to 1.24). CONCLUSIONS: Inequalities in T2DM risk persist in later life, both in relation to neighborhood-level and individual-level socioeconomic factors. Underlying modifiable risk factors continue to need to be addressed in deprived older age populations to reduce disease burden.

Risk factors for mortality in infancy and childhood in children with major congenital anomalies: A European population-based cohort study.

BACKGROUND: Preterm birth and young maternal age are known risk factors for infant and childhood mortality. There is limited knowledge of the impact of these risk factors in children born with major congenital anomalies (CAs), who have inherently higher risks of death compared with other children. OBJECTIVES: To investigate the risk factors for mortality up to age 10 years in children born with specific major CAs. METHODS: This population-based cohort study involved 150,198 livebirths from 1995 to 2014 in 13 European CA registries linked to mortality data. Cox proportional hazards models estimated the association of gestational age, maternal age and child's sex with death <1 year and 1-9 years for the whole cohort and by CA subgroup. Hazard ratios (HR) from each registry were pooled using multivariate meta-analysis. RESULTS: Preterm birth had a dose-response association with mortality; compared with infants born at 37+ weeks gestation, those born at <28, 28-31 and 32-36 weeks had 14.88 (95% CI 12.57, 17.62), 8.39 (95% CI 7.16, 9.85) and 3.88 (95% CI 3.40, 4.43) times higher risk of death <1 year, respectively. The corresponding risks at 1-9 years were 4.99 (95% CI 2.94, 8.48), 3.09 (95% CI 2.28, 4.18) and 2.04 (95% CI 1.69, 2.46) times higher, respectively. Maternal age <20 years (versus 20-34 years) was a risk factor for death <1 year (HR 1.30, 95% CI 1.09, 1.54) and 1-9 years (HR 1.58, 95% CI 1.19, 2.10). Females had 1.22 (95% CI 1.07, 1.39) times higher risk of death between 1 and 9 years than males. CONCLUSION: Preterm birth was associated with considerably higher infant and childhood mortality in children with CAs, comparable to estimates reported elsewhere for the background population. Additional risk factors included young maternal age and female sex. Information on risk factors could benefit clinical care and guide counselling of parents following CA diagnoses.

Cultural Influences on African Migrant Pregnant and Postnatal Women's Dietary Behaviours and Nutrition Support Needs in the UK.

Black women in the UK face significantly higher risks of overweight and obesity and adverse pregnancy outcomes compared to women from other ethnic groups. Maternal nutrition plays a pivotal role in influencing the health outcomes of women and their children, especially during preconception and pregnancy. Cultural and environmental factors significantly influence the dietary experiences of African women after migration. This study explored the unique nutrition-related challenges faced by African migrant pregnant and postnatal women in the UK, and their nutrition support needs. Interviews were conducted with 23 African migrant women living in the UK, who were either pregnant or had a pregnancy within the past 3 years. These were analysed thematically, resulting in five overarching themes: food rituals and beliefs, pregnancy cravings, limited access to culturally appropriate food, limited access to culturally appropriate and evidence-based nutritional guidance, and the focus on healthy weight. The study identified challenges that African migrant women face in balancing their cultural heritage with the UK food environment and dietary recommendations, including potential implications on their health and pregnancy outcomes. It emphasised the importance of addressing these challenges through culturally sensitive approaches and tailored interventions, to enable informed decision making and enhance health outcomes for these women.

Preconception and Pregnancy Nutrition Support for Women with a History of Bariatric Surgery: A Mixed-Methods Survey of Healthcare Professionals in the UK.

Preconception bariatric surgery improves obesity-related maternal pregnancy complications but may reduce the absorption of nutrients required for healthy fetal growth and development. Women who receive preconception nutritional support after bariatric surgery are less likely to have adverse pregnancy outcomes. This study aimed to investigate the provision of preconception and pregnancy-specific nutritional support for women having bariatric surgery in the UK. A mixed-methods survey was distributed to healthcare professionals working in obesity or maternity services between December 2018 and October 2019. We collected both quantitative and qualitative data which were analysed using a mixed-methods approach. We received 135 responses from online (n = 99) and postal (n = 36) questionnaires. Only 45% of participants reported being 'very familiar' with the preconception/pregnancy nutritional needs of this population. Barriers to providing nutritional support included: a lack of resources and time; poor communication both across services and with women; not having contact with women preconception; and a lack of information and guidance. Respondents felt that dietitians have the expertise in nutrition necessary to provide support; however, GPs and midwives have the most frequent patient access post-surgery, both before and during pregnancy. Optimal preconception and pregnancy-related nutritional support requires multidisciplinary care pre- and post-surgery, and healthcare professionals require training and guidance to inform practice.

Maternal Obesity and Patterns in Postnatal Diet, Physical Activity and Weight among a Highly Deprived Population in the UK: The GLOWING Pilot Trial.

Preconception obesity is associated with adverse pregnancy outcomes and deprivation. The postnatal period provides an opportunity for preconception intervention. There is a lack of published postnatal behaviour and weight data to inform intervention needs. Secondary analysis of the GLOWING study explored postnatal diet, physical activity (PA) and weight among women living with obesity in deprivation. Thirty-nine women completed food frequency and PA questionnaires and provided weight measurement(s) between 3-12 months postnatal. Women's diet and PA fell short of national guidelines, especially for fruit/vegetables (median 1.6-2.0 portions/day) and oily fish (0-4 g/day). PA was predominantly light intensity. Patterns in weight change across time points indicated postnatal weight loss compared with 1st (median -0.8 to -2.3 kg) and 3rd-trimester weights (-9.0 to -11.6 kg). Weight loss was higher among women without excessive gestational weight gain (GWG) (-2.7 to -9.7 kg) than those with excessive GWG (2.3 to -1.8 kg), resulting in postnatal weight measurements lower than their 1st trimester. These pilot data suggest preconception interventions should commence in pregnancy with a focus on GWG, and postnatal women need early support to achieve guideline-recommendations for diet and PA. Further research in a larger population could inform preconception intervention strategies to tackle inequalities in maternal obesity and subsequent pregnancy outcomes.
