“…Spontaneous preterm delivery is one of the most important issues that involves obstetricians and gynecologists because the care and treatment of the complications of the birth of a preterm baby incur a huge cost every year and sometimes cause irreparable emotional and psychological damage to families. Today, a high percentage of pregnant women have preterm birth (4.9%–6.2%), which has caused a lot of problems and costs for the health system ( Hoffman et al., 2016 ; Behboudi-Gandevani et al., 2023 ). Complications caused by spontaneous preterm delivery in babies include necrotizing enterocolitis, hyaline membrane disease, brain’s intraventricular hemorrhage, and if the baby survives, deafness, vision disorders, seizures, and neurological disorders ( Stamm et al., 2005 ).…”

BackgroundSpontaneous preterm delivery is defined as the beginning of the birth process before the 37th week of pregnancy. The presence of microorganisms in the fetal membranes is accompanied by an increase in the production of prostaglandin, one of the important factors associated with the prevalence of preterm birth. The invasion of microorganisms leads to the production of protease, coagulase, and elastase, which directly stimulate the onset of childbirth. We investigated the role of genital infections in women with preterm birth.MethodsThe present case-control study was conducted in the west of Iran on 100 women with spontaneous preterm delivery (following 24 weeks of gestation and before 36 weeks and 6 days) as the case group and 100 women with normal delivery as controls. A questionnaire was applied to collect the data. Polymerase chain reaction and pathological examination of the placenta were performed.ResultsThe average age in women with normal delivery (30.92 ± 5.10) in women with spontaneous preterm delivery (30.27 ± 4.93). The prevalence of Chlamydia trachomatis, Neisseria gonorrhea, Listeria monocytogenes, and Mycoplasma genitalium infections was zero in both groups. The highest prevalence of Gardnerella vaginalis was 19 (19%) in the case group and Ureaplasma parvum 15 (15%) in the control group. Also, Placental inflammation was zero in controls and 7(7%) in the patient group. There was a significant relationship between Gardnerella vaginalis bacteria and spontaneous preterm delivery.ConclusionThe results of our study showed that except for Gardnerella vaginalis bacteria, there is no significant relationship between the above bacterial infections and spontaneous preterm birth. Moreover, despite the significant reduction in the prevalence of many sexually transmitted infections in this research, it is still suggested to increase the awareness of people, including pregnant women, about the ways it can be transmitted by gynecologists and health and treatment centers.

The article reviews the literature on spontaneous preterm birth (PB) risk factors. The search for literature sources was conducted in the electronic databases Medline (PubMed), Scopus, Web of Science, eLibrary, and CyberLeninka for the last ten years using keywords such as preterm birth, epidemiology, perinatal outcomes, risk factors, and prognosis. PBs are a significant issue in modern obstetrics due to their widespread prevalence, contribution to perinatal morbidity and mortality, and the lack of reduction in their incidence in recent years, even in developed countries. Despite advancements in managing PB and care for mothers and premature newborns, there has been no decrease in the frequency of PBs. Therefore, studying risk factors for PBs is crucial for identifying pregnant women at risk and predicting the likelihood of PB during pregnancy, enabling the timely implementation of preventive measures. Keywords: Premature birth, frequency, risk factors, prediction.

Background/Objectives: The aim of this study is to assess the knowledge, attitudes, and practices of pregnant women and hospital staff regarding umbilical cord blood (UCB) donation and storage to understand its limitations in clinical practice. Methods: MEDLINE, Scopus, LILACS, EMBASE, Scielo.br, and PROSPERO were searched from inception to 30 November 2023 with no geographic or language restrictions. The study eligibility criteria included cross-sectional studies that interviewed pregnant women and/or hospital staff about their knowledge, attitudes, and practices regarding private or public storage. A random-effects restricted maximum-likelihood model with Freeman–Tukey Double arcsine transformation meta-analysis was carried out to calculate the pooled estimates. MOOSE guidelines were followed. STATA 14.1 was used for statistical analysis. The Newcastle–Ottawa Scale and ROBINS-I tool were used for quality and risk of bias assessments. Results: In total, 19 studies providing data for 19,904 pregnant women and 1245 hospital staff members were included. Pooled pregnant women awareness was 61% ((95% CI 0.60 to 0.62), I2 = 0%, τ2 = 0.00, Q = 11.0 (p = 0.950)), and 61% for hospital staff (95% CI 0.58 to 0.64), I2 = 0%, τ2 = 0.00, Q = 4.00 (p = 0.310)). In total, 57% ((95% CI 0.56 to 0.58), I2 = 0, τ2 = 0.00, Q = 4.00 (p = 0.320)) of pregnant women had a positive attitude about UCB, while 34% ((95% CI 0.32 to 0.36), I2 = 0%, τ2 = 0.00, Q = 4.00 (p = 0.310)) were in favor of donating UCB for research and 65% ((95% CI 0.63 to 0.66), I2 = 0%, τ2 = 0.00, Q = 4.0 (p = 0.350)) were planning UCB storage. A significant (p < 0.001) preference for public relative to private banking (51% ([95% CI 0.49 to 0.54], I2 = 0%, τ2 = 0.00, Q = 4.0 (p = 0.310)) vs. 12% ([95% CI 0.10 to 0.13], I2 = 0%, τ2 = 0.00, Q = 4.0 (p = 0.300))) was noted for pregnant women. The same was retrievable for professionals (84% ([95% CI 0.79 to 0.88], I2 = 0%, τ2 = 0.00, Q = 2.0 (p = 0.110)) vs. 6% ([95% CI 0.03 to 0.09], I2 = 0%, τ2 = 0.00, Q = 1.0 (p = 0.070); p < 0.001)). Conclusions: Despite these efforts, lack of knowledge and positive attitudes about UCB banking remain, emphasizing the need for increasing educational programs on the subject.
