Meconium-stained amniotic fluid during labor may be a protective factor for the offspring's childhood wheezing up to 3 years of age: the Japan Environment and Children's Study. Eur J Pediatr 2022; 181:3153-3162. [PMID: 35852596 DOI: 10.1007/s00431-022-04530-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Revised: 03/10/2022] [Accepted: 06/12/2022] [Indexed: 11/27/2022]
Abstract
UNLABELLED We aimed to evaluate the association between meconium-stained amniotic fluid during labor and offspring's childhood wheezing. This study analyzed the data of participants enrolled in the Japan Environment and Children's Study, a nationwide prospective birth cohort study, between 2011 and 2014. Data of women with singleton live births between 22 and 40 weeks' gestation were analyzed. Participants were categorized into two groups according to the presence or absence of meconium-stained amniotic fluid. The primary outcome measure was the offspring's childhood wheezing up to 3 years of age. A logistic regression model was used to calculate the adjusted odds ratio for childhood wheezing in children of women with meconium-stained amniotic fluid, considering those without meconium-stained amniotic fluid as a reference, taking into account the potential confounding factors affecting the incidence of wheezing. We analyzed data from 61,991 participants: 1796 (2.9%) participants had meconium-stained amniotic fluid during labor and 18,919 (30.5%) of the offspring had childhood wheezing. The adjusted odds ratios for the offspring's childhood wheezing were 0.89 (95% confidence interval, 0.79-0.99) in total participants, 0.87 (95% confidence interval, 0.78-0.97) in term births, and 2.00 (95% confidence interval, 0.98-4.09) in preterm births. CONCLUSIONS This study revealed a decreased incidence of childhood wheezing among the children of women with meconium-stained amniotic fluid in term births. By yet unknown mechanisms, meconium-stained amniotic fluid was associated with a decreased incidence of childhood wheezing in the offspring. Further studies are required to clarify the mechanism of one's own meconium in affecting their health condition. WHAT IS KNOWN • Meconium-stained amniotic fluid during labor is associated with several adverse perinatal outcomes, and meconium aspiration syndrome is associated with offspring's childhood asthma and wheezing. • Meconium-stained amniotic fluid during labor could be an independent protective factor for the offspring's dermatitis and skin rash. WHAT IS NEW • Whole cases with meconium-stained amniotic fluid during labor were associated with a decreased incidence of offspring's childhood wheezing up to 3 years of age. • This study may shed light on the effects of simple meconium-stained amniotic fluid on offspring's childhood health.

Abstract
Diaper dermatitis is a common type of irritant contact dermatitis occurring in infants and toddlers. Its occurrence is triggered by an unfavorable environment under the diaper, damage to skin integrity by fecal enzyme degradation, overhydration and disruption of the lipid bilayer structure facilitating the entry of irritants and microorganisms. In diaper dermatitis development, the central proinflammatory cytokines are IL-1α, IL-8 and TNF-α. The initial release of IL-1α and TNF-α starts a further cascade of pro-inflammatory chemo- and cytokines, resulting in inflammation and erythema of the skin. A recently recognized factor in diaper dermatitis is the composition of the skin microbiome; common pathogenic strains Candida albicans and Staphylococcus aureus are associated with skin irritation. The resulting impaired microbiome composition produces a local inflammatory response and may thus worsen the initial dermatitis clinical presentation and subsequent healing. Introduction of probiotics is an attractive treatment for microbiome modulation, which has shown success in other skin conditions in adults and children. Probiotics are thought to work as a protective shield against irritants, maintain low skin pH, secrete beneficial metabolites, and block pathogen invasion. There is preliminary evidence that certain probiotics given orally or topically could be used as a gentle intervention in diaper dermatitis.

[PMID: 33730429 DOI: 10.1002/ppul.25357] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 02/07/2021] [Accepted: 02/16/2021] [Indexed: 11/10/2022]
Abstract
OBJECTIVE Meconium stained amniotic fluid (MSAF) is a well-established risk factor for neonatal short-term respiratory complications. Little is known regarding the long-term morbidity. We investigated the possible association between MSAF and offspring respiratory morbidity. METHODS A population-based, cohort study of singleton deliveries occurring between 1991 and 2014 at a sole regional tertiary medical center was performed. Incidence of offspring respiratory related hospitalizations up to the age of 18 years were evaluated and compared to unexposed offspring. A Kaplan-Meier survival curve was used to compare cumulative respiratory morbidity incidence, and a Cox proportional hazards model was used to control for confounders. RESULTS During the study period 242,342 deliveries met the inclusion criteria. Of them, 14.7% (n = 35,609) were complicated with MSAF. Incidence of respiratory-related hospitalizations was significantly lower in children exposed to MSAF as compared to the unexposed group (4.5% vs. 4.9%, respectively; p < .01). Specifically, hospitalizations involving pneumonitis were significantly less common among the MSAF group (odds ratio, 0.35; 95% confidence interval [95% CI], 0.13-0.96; p = .03). The Kaplan-Meier survival curve demonstrated significantly lower total cumulative respiratory morbidity rates in the MSAF exposed group (log rank p < .01). In the Cox model, controlled for clinically relevant confounders, MSAF exhibited an independent and significant protective effect on long-term childhood respiratory morbidity (aHR, 0.91; 95% CI, 0.86-0.96; p < .01). CONCLUSIONS Fetal exposure to MSAF during labor appears to be associated with lower rates of long-term respiratory related hospitalizations in the offspring. Changes in offspring microbiome, as well as functional and anatomical modulations possibly resulting from MSAF exposure, might offer a plausible explanation of our findings.

Abstract
Human skin, our most environmentally exposed organ, is colonized by a vast array of microorganisms constituting its microbiome. These bacterial communities are crucial for the fulfillment of human physiological functions such as immune system modulation and epidermal development and differentiation. The structure of the human skin microbiome is established during the early life stages, starting even before birth, and continues to be modulated throughout the entire life cycle, by multiple host-related and environmental factors. This review focuses on extrinsic factors, ranging from cosmetics to the environment and antibacterial agents, as forces that impact the human skin microbiome and well-being. Assessing the impact of these factors on the skin microbiome will help elucidate the forces that shape the microbial populations we coexist with. Furthermore, we will gain additional insight into their tendency to stimulate a healthy environment or to increase the propensity for skin disorder development.

The effect of meconium-stained amniotic fluid on perinatal outcome in pregnancies complicated by preterm premature rupture of membranes. Arch Gynecol Obstet 2020; 301:1181-1187.

Abstract
PURPOSE To determine whether meconium-stained amniotic fluid (MSAF) encountered in pregnancies complicated by preterm premature rupture of membranes (PPROM) is associated with adverse maternal and perinatal outcome. METHODS A retrospective cohort study of all singleton pregnancies with PPROM and MSAF who delivered in a tertiary hospital at 24 + 0-36 + 6 weeks of gestation between 2007 and 2017. Women with PPROM-MSAF (study group) were compared to women with PPROM and clear amniotic fluid (control group). Controls were matched to cases according to age, gravidity, parity and gestational age at delivery in a 3:1 ratio. Primary outcome was defined as neonatal intensive care unit admission. Secondary outcomes were neonatal adverse outcomes, chorioamnionitis and placental abruption diagnosed clinically or by placental cultures and histology. RESULTS Seventy-five women comprised the study group and were matched to 225 women representing the control group. A significantly higher rate of neonatal intensive care unit admissions was noted in the study group compared to controls (61.3% vs. 45.7%, p = 0.03). Multivariate analysis demonstrated that MSAF is an independent risk factor for neonatal intensive care unit admission (adjusted OR = 2.82, 95% CI 1.39-5.75, p = 0.004). MSAF was found to be associated to higher rates of cesarean and operative vaginal deliveries (30.7% vs. 24.4% and 5.3% vs. 2.7%, p = 0.057, respectively) as well as to chorioamnionitis and placental abruption (33.3% vs. 19.3%, p = 0.034 and 16.0% vs. 7.7%, p = 0.021, respectively). CONCLUSION MSAF is associated with higher frequencies of adverse perinatal outcome when compared to clear amniotic fluid in pregnancies complicated by PPROM.

Abstract
A successful pregnancy depends on not only the tolerance of the fetal immune system by the mother but also resistance against the threat of hazardous microorganisms. Infection with pathogenic microorganisms during pregnancy may lead to premature delivery, miscarriage, growth restriction, neonatal morbidity, and other adverse outcomes. Moreover, the host also has an intact immune system to avoid these adverse outcomes. It is important to note the presence of normal bacteria in the maternal reproductive tract and the principal role of the maternal-placental-fetal interaction in antimicrobial immunity. Previous studies mainly focused on maternal infection during pregnancy. However, this review summarizes the new views on the study of the maternal microbiome and expounds the innate immune defense mechanism of the maternal vagina and decidua as well as how cytotrophoblasts and syncytiotrophoblasts recognize and kill bacteria in the placenta. Fetal immune systems, thought to be weak, also exhibit an immune defense function that is indispensable for maintaining the safety of the fetus. The skin, lungs, and intestines of the fetus during pregnancy constitute the main immune barriers. These findings will provide a new understanding of the effects of normal microbial flora and how the host resists harmful microbes during pregnancy. We believe that it may also contribute to the reference on the clinical prevention and treatment of gestational infection to avoid adverse pregnancy outcomes.
