BACKGROUND AND AIMS
Evidence regarding perinatal low-calorie (or artificial) sweetener (LCS) consumption and its effect on maternal health outcomes is limited and inconclusive. The primary outcomes of our systematic review and meta-analysis were the effect of preconception and pregnancy LCS exposure on reproductive and pregnancy outcomes. Secondary outcomes included long-term maternal health.
METHODS
A systematic search of electronic databases, including PubMed, Embase, CINAHL, the Cochrane Library, Scopus, Web of Science, PsycINFO, ProQuest Health and Medical, ClinicalTrials.gov and Google Scholar, was conducted up to 20 November 2023. Primary studies, including clinical trials, cohort studies, case-control studies, which reported any LCS consumption during perinatal period and pregnancy and maternal health outcomes were eligible. A random effects model with restricted maximum likelihood estimation was used for the meta-analysis. We appraised the quality of the included studies using the National Institute of Health study quality appraisal tool and the overall quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation tool.
RESULTS
A total of 19 eligible studies with 203,706 participants were included. LCS consumption during pregnancy was associated with 11% increased risk of preterm birth (RR = 1.11, 95% CI: 1.07-1.16, I = 0.01%) and 42% increased risk of gestational diabetes (RR = 1.42, 95% CI: 0.98-2.04, I = 67.60%) compared with no consumption, however, the effect size for gestational diabetes was not precise as the 95% CI indicated that the effect estimate could range from 2% lower risk to 204% (or 2.04 times) higher risk. We found no association between LCS consumption during pregnancy and gestational weight gain (standardized mean difference (SMD) = 0.04; 95% CI: -0.17 - 0.24, I = 41.31%) or gestational age at birth (SMD = 0.00; 95% CI: -0.13 - 0.14, I = 80.13%). The effect of LCS consumption on reproductive treatment outcomes were inconsistent.
CONCLUSIONS
Based on the evidence available, LCS consumption in pregnancy was associated with increased risk of preterm birth and gestational diabetes. Robust research, such as well-designed randomized trials and large prospective cohort studies, is required to confirm the causal effect of LCS consumption during perinatal period on adverse maternal health outcomes.

BACKGROUND
Caesarean section (CS) rate increased dramatically worldwide, exceeding the World Health Organization's benchmark (10-15 %) in many countries. This rate varies in different regions of the continent. Using various study designs, researchers from across East African countries investigated the prevalence of caesarean section and the factor associated with it but no study shows a pooled prevalence of caesarean section in the Eastern African region. Therefore, this review aimed to systematically summarize and estimate the pooled prevalence of caesarean section and its associated factors in Eastern Africa, 2023.
METHODS
PubMed, Web of Science, EMBASE, Scopus and CINAHL were rigorously searched to find relevant studies. All identified observational studies reporting the prevalence of CS and its associated factors in East Africa published till August 2023 were considered. Heterogeneity across the studies was evaluated using the I test. Publication bias was assessed by funnel plot and Egger's regression test. Finally, a random effect meta-analysis model was computed to estimate the pooled prevalence of CS and qualitative analysis was employed for associated factors. The study protocol was registered in PROSPERO.
RESULTS
This review was assessed using twenty-six eligible studies from a total of 2223 articles with a total of 600,431 participants. In this meta-analysis, the pooled prevalence of caesarean section in Eastern Africa was 24.0 % (95%CI: 22-27 %). The highest pooled prevalence of caesarean section was in Ethiopia, 28.30 % (95%CI; 21.3-35.2 %), and the lowest was seen in Uganda, 11.9 % (95%CI; 7.9-15.9 %). Urban residency, having high level of wealth asset, education level college and above, advanced maternal age, big birth weight, history of previous caesarean section, private institution delivery, multiple pregnancies, pregnancy-induced hypertension, antepartum haemorrhage and fetal malpresentation were linked with a greater likelihood of having CS.
CONCLUSIONS
and recommendation: The overall pooled prevalence of CS in Eastern Africa was high compared to the WHO proposed recommended range. Therefore, the finding implies that each East African countries Ministry of Health and health care professionals shall be given particular emphasis made on strengthening antenatal care services and ensure more women have access to skilled healthcare professionals during childbirth. This can help in providing appropriate interventions, support to women and reducing the need for emergency and unnecessary CSs. The result of this research are a baseline data for future researchers to conduct further studies to better understand the reasons behind the high rates and identify potential interventions and solutions specific to the African context.: CRD42023440131.

The British Journal of General Practice... Jul 2024Routine primary care data may be a valuable resource for preconception health research and informing provision of preconception care.
BACKGROUND
Routine primary care data may be a valuable resource for preconception health research and informing provision of preconception care.
AIM
To review how primary care data could provide information on the prevalence of preconception indicators and examine associations with maternal and offspring health outcomes.
DESIGN AND SETTING
Systematic review of observational studies using UK routine primary care data.
METHOD
Literature searches were conducted in five databases (March 2023) to identify observational studies that used national primary care data from individuals aged 15-49 years. Preconception indicators were defined as medical, behavioural and social factors that may impact future pregnancies. Health outcomes included those that may occur during and after pregnancy. Screening, data extraction and quality assessment were conducted by two reviewers.
RESULTS
From 5,259 records screened, 42 articles were included. The prevalence of 30 preconception indicators was described for female patients, ranging from 0.01% for sickle cell disease to >20% for each of advanced maternal age, previous caesarean section (among those with a recorded pregnancy), overweight, obesity, smoking, depression and anxiety (irrespective of pregnancy). Few studies reported indicators for male patients (n=3) or associations with outcomes (n=5). Most studies had low risk of bias, but missing data may limit generalisability.
CONCLUSION
Findings demonstrate that routinely collected UK primary care data can be used to identify patients preconception care needs. Linking primary care data with health outcomes collected in other datasets is underutilised but could help quantify how optimising preconception health and care can reduce adverse outcomes for mothers and children.

Nutrition Reviews Jul 2024Previous research linked vitamin D deficiency in pregnancy to adverse pregnancy outcomes.
CONTEXT
Previous research linked vitamin D deficiency in pregnancy to adverse pregnancy outcomes.
OBJECTIVE
Update a 2017 systematic review and meta-analysis of randomized controlled trials (RCTs) on the effect of vitamin D supplementation during pregnancy, identify sources of heterogeneity between trials, and describe evidence gaps precluding a clinical recommendation.
DATA SOURCES
The MEDLINE, PubMed, Europe PMC, Scopus, Cochrane Database of Systematic Reviews, Web of Science, and CINAHL databases were searched. Articles were included that reported on RCTs that included pregnant women given vitamin D supplements as compared with placebo, no intervention, or active control (≤600 IU d-1). Risk ratios (RRs) and mean differences were pooled for 38 maternal, birth, and infant outcomes, using random effects models. Subgroup analyses examined effect heterogeneity. The Cochrane risk of bias tool was used.
DATA EXTRACTION
Included articles reported on a total of 66 trials (n = 17 276 participants).
DATA ANALYSIS
The median vitamin D supplementation dose was 2000 IU d-1 (range: 400-60 000); 37 trials used placebo. Antenatal vitamin D supplementation had no effect on the risk of preeclampsia (RR, 0.81 [95% CI, 0.43-1.53]; n = 6 trials and 1483 participants), potentially protected against gestational diabetes mellitus (RR, 0.65 [95% CI, 0.49-0.86; n = 12 trials and 1992 participants), and increased infant birth weight by 53 g (95% CI, 16-90; n = 40 trials and 9954 participants). No effect of vitamin D on the risk of preterm birth, small-for-gestational age, or low birth weight infants was found. A total of 25 trials had at least 1 domain at high risk of bias.
CONCLUSION
Additional studies among the general pregnant population are not needed, given the many existing trials. Instead, high-quality RCTs among populations with low vitamin D status or at greater risk of key outcomes are needed. Benefits of supplementation in pregnancy remain uncertain because current evidence has high heterogeneity, including variation in study context, baseline and achieved end-line 25-hydroxyvitamin D level, and studies with high risk of bias.

Effect of preconception multiple micronutrients vs. iron-folic acid supplementation on maternal and birth outcomes among women from developing countries: a systematic review and meta-analysis.
BACKGROUND
Maternal malnutrition affects the somatic growth of the fetus and subsequent adverse events during infancy and childhood period. Though trials have been conducted on multiple micronutrient (MMN) supplements initiated during the preconception period, there is no collated evidence on this.
MATERIALS AND METHODS
We performed a systematic review of published trials with the application of Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The searches were conducted until 30 September 2023. Meta-analysis was performed using Review Manager 5 software. The primary objective was to compare the effect of preconception MMN vs. iron-folic acid (IFA) supplementation on newborn anthropometric parameters at birth.
RESULTS
Of the 11,832 total citations retrieved, 12 studies with data from 11,391 participants [Intervention = 5,767; Control = 5,624] were included. For the primary outcome, there was no significant difference in the birth weight [MD, 35.61 (95% CI, -7.83 to 79.06), = 0.11], birth length [MD, 0.19 (95% CI, -0.03 to 0.42), = 0.09], and head circumference [MD, -0.25 (95% CI, -0.64 to -0.14), = 0.22] between the MMN and control groups. For all the secondary outcomes [except for small for gestational age (SGA) and low birth weight (LBW)], the difference between the MMN and control groups was not significant. The GRADE evidence generated for all the outcomes varied from "very low to moderate certainty."
CONCLUSION
A "very low certainty" of evidence suggests that MMN supplementation may not be better than routine IFA supplementation in improving newborn anthropometric parameters (weight, length, and head circumference). The adverse events resulting from the supplementation were not significant. We need better quality uniformly designed RCTs before any firm recommendation can be made.: identifier (CRD42019144878: https://www.crd.york.ac.uk/prospero/#searchadvanced).

Review
INTRODUCTION
To compare neonatal, obstetrical, and maternal outcomes associated with outpatient versus inpatient management of pregnancies with preterm prelabor rupture of membranes (PPROM).
MATERIAL AND METHODS
A search of MEDLINE, EMBASE, the Cochrane Database and Central Register from January 1, 1990 to July 31, 2023 identified randomized controlled trials (RCTs) and cohort studies comparing outpatient with inpatient management for pregnant persons diagnosed with PPROM before 37 weeks' gestation. No language restriction was applied. We applied a random effects model for meta-analysis. Trustworthiness was assessed using recently published guidance and Risk of bias using the RoB 2.0 tool for RCTs and ROBINS-I tool for cohort studies. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach was used to assess the certainty of evidence (COE). Outcomes of interest included perinatal mortality, neonatal morbidities, latency and gestational age at delivery, and maternal morbidities. RCTs and cohort studies were analyzed separately. This study was registered in the International Prospective Register of Systematic Reviewsr: CRD42022295275.
RESULTS
From 2825 records, two RCTs and 10 cohort studies involving 1876 patients were included in the review and meta-analysis. Outpatient management protocols varied but generally included brief initial hospitalization, strict eligibility criteria, and surveillance with laboratory and ultrasound investigations. Outpatient management showed lower rates of neonatal respiratory distress syndrome (cohort: RR 0.63 [0.52-0.77, very low COE]), longer latency to delivery (RCT: MD 7.43 days [1.14-13.72 days, moderate COE], cohort: MD 8.78 days [2.29-15.26 days, low COE]), higher gestational age at birth (cohort: MD 7.70 days [2.02-13.38 days, low COE]), lower rates of Apgar scores <7 at 5 min of life (cohort: RR 0.66 [0.50-0.89, very low COE]), and lower rates of histological chorioamnionitis (cohort: RR 0.74 [0.62-0.89, low COE]) without increased risks of adverse neonatal, obstetrical, or maternal outcomes.
CONCLUSIONS
Meta-analysis of data from RCTs and cohort studies with very low-to-moderate certainty of evidence indicates that further high-quality research is needed to evaluate the safety and potential benefits of outpatient management for selected PPROM cases, given the moderate-to-high risk of bias in the included studies.

OBJECTIVES
Respiratory syncytial virus (RSV) is a leading cause of acute lower respiratory infection (ALRI) in young children. With substantial advances in RSV research, we aimed to conduct an updated systematic review of risk factors for RSV-ALRI in children under five years.
METHODS
We updated our previously published literature search to November 2022 among three English databases and additionally searched three Chinese databases (from January 1995) to identify all relevant publications. We performed random-effects meta-analyses to estimate the pooled odds ratio and 95% confidence interval (CI) for each risk factor and each outcome (RSV-ALRI in the community and RSV-ALRI hospitalisation).
RESULTS
A total of 47 studies were included (26 from the updated search). Indoor air pollution was identified as a possible risk factor for RSV-ALRI in the community (OR 1.45, 95% CI: 1.10-1.90). The identified risk factors for RSV-ALRI hospitalisation fall into four categories: demographic (male sex, Māori and Pacific ethnicities vs European or other ethnicities), pre- and post- neonatal (prematurity, low birth weight, small for gestational age, maternal smoking during pregnancy or lactation, maternal age <30 years vs 30-34 years, multiparity, caesarean section vs vaginal), household and environmental (having siblings, passive smoking, maternal asthma, daycare centre attendance), and health and medical conditions (any chronic diseases, bronchopulmonary dysplasia, HIV infections, congenital heart disease, Down syndrome, cystic fibrosis, previous asthma). The pooled ORs ranged from 1.14 to 4.55.
CONCLUSIONS
Our findings on the risk factors for RSV-ALRI help identify RSV high-risk groups, which has important implications for RSV prevention at both individual and population levels.

INTRODUCTION
The aim of this systematic review and meta-analysis was to evaluate fetal cardiac function in fetuses of mothers with diabetes compared to those of mothers without diabetes using 2D-STE.
METHODS
Embase, MEDLINE and CENTRAL were searched for observational studies on 2D-STE fetal left and right ventricular global longitudinal strain and strain rate that included singleton, non-anomalous pregnancies complicated by pregestational or gestational diabetes mellitus compared to uncomplicated pregnancies. The strain values were pooled per 4 weeks of gestation for meta-analysis using random-effects models.
RESULTS
Fifteen studies met the criteria, including 990 fetuses of diabetic mothers and 1,645 control fetuses. The study design was cross-sectional in fourteen studies and longitudinal in one study. Gestational age, type of diabetes, ultrasound device and 2D-STE software varied between the studies. Glycemic control and type of treatment were often lacking. In fetuses of diabetic mothers versus healthy mothers, left ventricular strain was significantly decreased (7 studies), increased (1 study) or not significantly different (7 studies). Right ventricular strain was decreased (7 studies), increased (1 study) or not different (2 studies). Left ventricular strain rate was decreased (3 studies), increased (1 study) or not different (2 studies). Right ventricular strain rate was increased (1 study) or not different (2 studies).
CONCLUSION
Fetuses of mothers with diabetes show evidence of systolic dysfunction, which is more visible in the right ventricle. Contradictory results are probably due to suboptimal study designs and variation in gestational age, diabetes severity, image acquisition and software. Large prospective longitudinal studies are needed to assess fetal myocardial function with 2D-STE in pregestational diabetes mellitus type 1 and 2 and gestational diabetes mellitus pregnancies. The influence of glycemic control, BMI and treatment should be evaluated.

The dietary supplements effect on metabolic markers in non-pharmacologically managed gestational diabetes mellitus patients: a systematic review and meta-analysis and meta-regression of randomized controlled trials.
BACKGROUND
Although several randomized clinical trials have tested the effect of prenatal dietary supplements on plasma glucose and lipid levels in non-pharmacologically managed gestational diabetes mellitus patients (GDM), a rigorous meta-analytic compendium lacks in the context. Therefore, this study aims to address this evidence gap.
METHOD
Eligible trials retrieved from searches in the PubMed, Embase, and Scopus databases were appraised using the Revised Cochrane risk-of-bias tool for randomized trials (RoB 2). The weighted mean differences (WMD) between dietary supplements and placebo were estimated using random-effect meta-analysis models for plasma glycemic and lipid markers. Meta-regression analysis ensued for effect modifier identification. The statistical significance estimation happened at < 0.05 (95% confidence interval).
RESULTS
This review included 19 trials (mostly Iranian and of low risk of bias primarily) of > 8000 GDM patients. Meta-analysis showed favorable effects of dietary supplementation on fasting plasma glucose (WMD: -5.42 mg/dL, p < 0.001), homeostasis model assessment indexes- insulin resistance (HOMA-IR; WMD: -1.02, p < 0.001), quantitative insulin sensitivity check index (WMD: 0.01, p < 0.001), total cholesterol (TC; WMD: -7.70 mg/dL, = 0.006), triglycerides (WMD: -10.23 mg/dL, = 0.0083), TC/high-density lipoprotein (WMD: -0.31 mg/dL, < 0.001), low-density lipoprotein (WMD: -5.79 mg/dL; < 0.001) and very-low-density lipoprotein (WMD: -5.67 mg/dL, < 0.001) levels. However, the HOMA- ß-cell function didn't increase (WMD: -17.91, < 0.001). Baseline maternal age ( = 0.28, = 0.014) and GDM diagnostic criteria ( = 0.90, = 0.012) were effect moderators of HOMA-IR and body mass index (BMI) ( = 6.07, = 0.022) and supplement type (solo versus combined) ( = 14.99, = 0.006) were effect moderators of triglyceride levels.
CONCLUSION
Altogether, antenatal dietary supplements achieved control over plasma glycemic and lipid profiles in non-pharmacologically treated GDM patients. Maternal age and GDM diagnostic criteria moderated HOMA-IR levels. BMI and supplement-type moderated triglyceride levels.

Review
Bladder cancer (BCa) represents the second most common malignancy of the genitourinary tract. The major risk factors include age, gender, smoking attitude, and occupational exposure, while the exact etiopathogenesis is still uncertain. Patients diagnosed with a BCa showing invasion of the muscle layer below the submucosa must undergo radical cystectomy (RC) with urinary diversion (UD). Many different surgical approaches to UD have been developed. Packaging an orthotopic neobladder (ON) with a bowel tract represents the gold standard when certain patient selection criteria are satisfied. Using PRISMA guidelines, we performed a systematic review assessing early (within 90 days) and late (beyond 90 days) post-procedural complications of different ON surgical approaches. A comprehensive systematic search was conducted in PubMed, Scopus, and Google Scholar databases to identify papers starting from 2012 using dedicated keywords ("neobladder", "orthotopic neobladder", "complications'' and "outcomes"). A total of 27 articles were found to satisfy the inclusion criteria and selected. Although the ON is a safe procedure that guarantees the patient the best quality of life (QoL), it is not free from risks. Many complications could occur during and after the surgical time which imposes the necessity of strict follow-up and careful checks over time, which should be properly discussed with patients before.
