Meta-Analysis Review
OBJECTIVES
The purpose of this study was to compare and determine whether there were any differences in clinical outcomes between pregnant and non-pregnant women who had been infected with COVID-19.
METHODS
A literature search was performed in 9 databases on November 20, 2021. The relative risk (RR) with 95% confidence interval (95% CI) was used to estimate the effect of pregnancy on COVID-19 outcomes. The I square value was used to assess heterogeneity, and the random or the fixed-effects model were adopted. Sensitivity and publication bias analyses were performed.
RESULTS
This study included 8 published studies with 859,278 COVID-19 female patients. The incidences of fever and cough among pregnant women with COVID-19 were 19.07% and 28.79%, respectively. Pregnancy was associated with significantly increased risks of intensive care unit (ICU) admission (RR = 2.23, 95% CI = 1.58-3.16) and ventilation (RR = 2.13, 95% CI = 1.06-4.28), but was not associated with a statistically significant increase in mortality.
CONCLUSIONS
Our results suggest that pregnant women with COVID-19 have a significantly higher probability of being hospitalized to the ICU and ventilation than non-pregnant women with COVID-19. To avoid these adverse outcomes, pregnant women should take precautions (for example, reduce going out, maintain social distance, and wear a mask) to avoid COVID-19 infection. Finally, additional research into the fetal outcomes is required to better investigate the impact of COVID-19 on pregnancy.

Meta-Analysis
OBJECTIVES
A conflicting body of evidence suggests localized periodontal inflammation spreads systemically during pregnancy inducing adverse pregnancy outcomes. This systematic review and meta-analysis aim to specifically evaluate the relationship between periodontitis and preeclampsia.
METHODS
Electronic searches were carried out in Medline, Pubmed, Embase, Lilacs, Cochrane Controlled Clinical Trial Register, CINAHL, ClinicalTrials.gov, and Google Scholar with no restrictions on the year of publication. We identified and selected observational case-control and cohort studies that analyzed the association between periodontal disease and preeclampsia. This meta-analysis was conducted following the PRISMA checklist and MOOSE checklist. Pooled odds ratios, mean difference, and 95% confidence intervals were calculated using the random effect model. Heterogeneity was tested with Cochran's Q statistic.
RESULTS
Thirty studies including six cohort- and twenty-four case-control studies were selected. Periodontitis was significantly associated with increased risk for preeclampsia (OR 3.18, 95% CI 2.26 - 4.48, p < 0.00001), especially in a subgroup analysis including cohort studies (OR 4.19, 95% CI 2.23 - 7.87, p < 0.00001). The association was even stronger in a subgroup analysis with lower-middle-income countries (OR 6.70, 95% CI 2.61 - 17.19, p < 0.0001).
CONCLUSIONS
Periodontitis appears as a significant risk factor for preeclampsia, which might be even more pronounced in lower-middle-income countries. Future studies to investigate if maternal amelioration of periodontitis prevents preeclampsia might be warranted.

Meta-Analysis Review
OBJECTIVE
The World Health Organization has recently declared a monkeypox outbreak as a public health emergency of global concern. The main aim of this systematic review was to ascertain the maternal and perinatal outcomes of pregnancies complicated by monkeypox infection.
DATA SOURCES
The Medline, Embase, and Cochrane databases were searched on June 25, 2022 utilizing combinations of the relevant medical subject heading terms, key words, and word variants for "monkeypox" and "pregnancy."
STUDY ELIGIBILITY CRITERIA
The search and selection criteria were restricted to the English language.
METHODS
The outcomes observed were miscarriage; intrauterine, neonatal, and perinatal death; preterm birth, vertical transmission, and maternal symptoms. A metaanalysis of proportions was used to analyze the data.
RESULTS
Four studies were included. All the cases in the present systematic review presented with symptoms and signs of monkeypox infection. There was no case of maternal death. Miscarriage occurred in 39% of cases (95% confidence interval, 0-89.0), whereas intrauterine fetal death occurred in 23.0% (95% confidence interval, 0-74.0) of cases. The overall incidence of late fetal and perinatal loss was 77.0% (95% confidence interval, 26.0-100), whereas only 23% (95% confidence interval, 0-74.0) of the included fetuses survived to birth. The incidence of preterm birth before 37 weeks of gestation was 8.0% (95% confidence interval, 0-62.0). Vertical transmission occurred in 62.0% (95% confidence interval, 3.0-100) of cases. When stratifying the analysis according to gestational age at infection, fetal loss was found to occur in 67.0% (95% confidence interval, 9.0-99.0) of cases with first-trimester infection and in 82.0% (95% confidence interval, 17.0-100) of those with second-trimester infection.
CONCLUSION
Monkeypox infection in pregnancy is associated with a high risk of perinatal loss and vertical transmission. The preliminary results from this systematic review affected by a very small number of included cases highlight the need for thorough maternal and fetal surveillance in pregnancies complicated by monkeypox infection.

Meta-Analysis Review
BACKGROUND
Disparities in health outcomes between immigrant and native-origin populations, particularly pregnant women, pose significant challenges to healthcare systems. The aim of this systematic-review and meta-analysis was to investigate the risk of adverse pregnancy outcomes among immigrant-women compared to native-origin women in the host country.
METHODS
PubMed (including MEDLINE), Scopus, and Web of Science were searched to retrieve studies published in English language up to September 2020. All observational studies examining the prevalence of at least one of the short-term single pregnancy outcomes for immigrants who crossed international borders compared to native-origin pregnant population were included. The meta-prop method was used for the pooled-estimation of adverse pregnancy-outcomes' prevalence. For pool-effect estimates, the association between the immigration-status and outcomes of interest, the random-effects model was applied using the model described by DerSimonian and Laird. I statistic was used to assess heterogeneity. The publication bias was assessed using the Harbord-test. Meta-regression was performed to explore the effect of geographical region as the heterogeneity source.
FINDINGS
This review involved 11 320 674 pregnant women with an immigration-background and 56 102 698 pregnant women as the native-origin population. The risk of emergency cesarean section (Pooled-OR = 1.1, 95%CI = 1.0-1.2), shoulder dystocia (Pooled-OR = 1.1, 95%CI = 1.0-1.3), gestational diabetes mellites (Pooled-OR = 1.4, 95%CI = 1.2-1.6), small for gestational age (Pooled-OR=1.3, 95%CI = 1.1-0.4), 5-min Apgar less than 7 (Pooled-OR = 1.2, 95%CI = 1.0-1.3) and oligohydramnios (Pooled-OR = 1.8, 95%CI = 1.0-3.3) in the immigrant women were significantly higher than those with the native origin background. The immigrant women had a lower risk of labor induction (Pooled-OR = 0.8, 95%CI = 0.7-0.8), pregnancy induced hypertension (Pooled-OR = 0.6, 95%CI = 0.5-0.7) preeclampsia (Pooled-OR = 0.7, 95%CI = 0.6-0.8), macrosomia (Pooled-OR = 0.8, 95%CI = 0.7-0.9) and large for gestational age (Pooled-OR = 0.8, 95%CI = 0.7-0.8). Also, the risk of total and primary cesarean section, instrumental-delivery, preterm-birth, and birth-trauma were similar in both groups. According to meta-regression analyses, the reported ORs were not influenced by the country of origin.
CONCLUSION
The relationship between the immigration status and adverse perinatal outcomes indicated a heterogenous pattern, but the immigrant women were at an increased risk of some important adverse pregnancy outcomes. Population-based studies with a focus on the various aspects of this phenomena are required to explain the source of these heterogenicities.

Meta-Analysis Review
Vaginal bleeding during pregnancy has been recognised as a significant risk factor for adverse pregnancy outcomes. This study aimed to investigate the association between vaginal bleeding during the first trimester of pregnancy and clinical adverse effects using a systematic review and meta-analysis. Databases of Scopus, Web of Science, PubMed (including Medline), Cochrane Library and Science Direct were searched until June of 2023. Data analysis using statistical test fixed- and random-effects models in the meta-analysis, Cochran and meta-regression. The quality of the eligible studies was assessed by using the Newcastle-Ottawa Scale checklist (NOS). A total of 46 relevant studies, with a sample size of 1,554,141 were entered into the meta-analysis. Vaginal bleeding during the first trimester of pregnancy increases the risk of preterm birth (OR: 1.8, CI 95%: 1.6-2.0), low birth weight (LBW; OR: 2.0, CI 95%: 1.5-2.6), premature rupture of membranes (PROMs; OR: 2.3, CI 95%: 1.8-3.0), abortion (OR: 4.3, CI 95%: 2.0-9.0), stillbirth (OR: 2.5, CI 95%: 1.2-5.0), placental abruption (OR: 2.2, CI 95%: 1.4-3.3) and placenta previa (OR: 1.9, CI 95%: 1.5-2.4). Vaginal bleeding in the first trimester of pregnancy is associated with preterm birth, LBW, PROMs, miscarriage, stillbirth, placental abruption and placenta previa. Therefore, physicians or midwives need to be aware of the possibility of these consequences and manage them when they occur.

Review
BACKGROUND
Herbal and homeopathic remedies have been used to assist with child bearing and pregnancy for centuries. Allopathic ('Western') medicine is traditionally avoided during pregnancy because of limited drug trials and the suspected teratogenic effects of these medications. This has led to an increase in the use of herbal and homeopathic remedies, asthey are viewed to have no teratogenic effect on the developing foetus. Health providers are faced with questions from their clients regarding the safety of these remedies, but much of the evidence about these herbal and homeopathic remedies is anecdotal and few remedies havebeen tested scientifically.
OBJECTIVES
By conducting a systematic review, the primary objective was to evaluate maternal and neonatal outcomes of ingested herbal and homeopathic remedies during pregnancy.
METHOD
A systematic review was conducted to synthesise all the evidence with the purpose of evaluating the safety of herbal and homeopathic remedies based on adverse maternal and neonatal outcomes. Only randomised and quasi-randomised controlled trials that met allinclusion criteria were included in the review.
RESULTS
The ingestion of ginger for nausea and vomiting during pregnancy was shown to have no harmful maternal or neonatal effects. Ingestion of castor oil for induction of labour showed a tendency towards an increase in the incidence of caesarean section and meconiumstained liquor, warranting further research into its safety issues.
CONCLUSION
Larger randomised controlled trials need to be conducted, especially in South Africa, to establish the safety and efficacy of commonly-used remedies.

BACKGROUND
Systematic reviews often conclude low confidence in the results due to heterogeneity in the reported outcomes. A Core Outcome Set (COS) is an agreed standardised collection of outcomes for a specific area of health. The outcomes included in a COS are to be measured and summarized in clinical trials as well as systematic reviews to counteract this heterogeneity.
AIM
The aim is to identify, compile and assess final and ongoing studies that are prioritizing outcomes in the area of pregnancy and childbirth.
METHODS
All studies which prioritized outcomes related to pregnancy and childbirth using consensus method, including Delphi surveys or consensus meetings were included. Searches were conducted in Ovid MEDLINE, EMBASE, PsycINFO, Academic Search Elite, CINAHL, SocINDEX and COMET databases up to June 2021. For all studies fulfilling the inclusion criteria, information regarding outcomes as well as population, method, and setting was extracted. In addition, reporting in the finalized studies was assessed using a modified version of the Core Outcome Set-STAndards for Reporting.
RESULTS
In total, 27 finalized studies and 42 ongoing studies were assessed as relevant and were included. In the finalized studies, the number of outcomes included in the COS ranged from 6 to 51 with a median of 13 outcomes. The majority of the identified COS, both finalized as well as ongoing, were relating to physical complications during pregnancy.
CONCLUSION
There is a growing number of Core Outcome Set studies related to pregnancy and childbirth. Although several of the finalized studies follow the proposed reporting, there are still some items that are not always clearly reported. Additionally, several of the identified COS contained a large number (n > 20) outcomes, something that possibly could hinder implementation. Therefore, there is a need to consider the number of outcomes which may be included in a COS to render it optimal for future research.

Review
Flood is one of the natural disasters with high prevalence in the world. The aim of this research was to investigate the effect of flood on pregnancy outcome and pregnancy complication such as preterm birth, LBW, SGA, stillbirth, spontaneous abortion, preeclampsia and eclampsia. This is a systematic review based on the PRISMA model that examines pregnancy disorder, pregnancy complication, and reproductive outcomes in floods. For fulfilling of the objectives of the research, related keywords were identified using Mesh and Emtree databases. Then the search was done in the electronic database of Medline, Web of Science, Embase, scopus until 2021.2.10. The search strategy in the Medline database. Database searches resulted in 823 non-duplicate records. After reading the abstracts, 808 articles were excluded. 15 abstracts were eligible for the study, which their full texts were provided. Finally based on inclusion and exclusion criteria 7 articles were included in this study. After flood, the rate of LBW birth and gestational hypertension increases. However, there is no significant difference in preterm birth rates. Pregnancy complications can be reduced or prevented by starting prenatal care early and also by controlling risk factors such as reducing smoking and alcohol consumption.

Sexually Transmitted Infections May 2022To examine associations between infection during pregnancy and adverse outcomes. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
To examine associations between infection during pregnancy and adverse outcomes.
METHODS
We did a systematic review of observational studies. We searched Medline, EMBASE, the Cochrane Library and CINAHL up to 11 August 2021. Studies were included if they compared preterm birth, spontaneous abortion, premature rupture of membranes, low birth weight or perinatal death between women with and without . Two reviewers independently assessed articles for inclusion and extracted data. We used random-effects meta-analysis to estimate summary ORs and adjusted ORs, with 95% CIs, where appropriate. Risk of bias was assessed using established checklists.
RESULTS
We identified 116 records and included 10 studies. Women with were more likely to experience preterm birth in univariable analyses (summary unadjusted OR 1.91, 95% CI 1.29 to 2.81, I=0%, 7 studies). The combined adjusted OR was 2.34 (95% CI 1.17 to 4.71, I=0%, 2 studies). For spontaneous abortion, the summary unadjusted OR was 1.00 (95% CI 0.53 to 1.89, I=0%, 6 studies). The adjusted OR in one case-control study was 0.9 (95% CI 0.2 to 3.8). Unadjusted ORs for premature rupture of membranes were 7.62 (95% CI 0.40 to 145.86, 1 study) and for low birth weight 1.07 (95% CI 0.02 to 10.39, 1 study). For perinatal death, the unadjusted OR was 1.07 (95% CI 0.49 to 2.36) in one case-control and 38.42 (95% CI 1.45 to 1021.43) in one cohort study. These two ORs were not combined, owing to heterogeneity. The greatest risk of bias was the failure in most studies to control for confounding.
CONCLUSION
might be associated with an increased risk of preterm birth. Further prospective studies, with adequate control for confounding, are needed to understand the role of in adverse pregnancy outcomes. There is insufficient evidence to indicate routine testing and treatment of asymptomatic in pregnancy.
