Obesity and periodontal disease could synergistically amplify the inflammatory and oxidative status, resulting in increased local and systemic biomarkers particularly when GDM is diagnosed.
Maternal obesity is associated with inflammation and oxidative stress, strongly impacting the intrauterine environment with detrimental consequences for both mother and offspring. The saliva is a non-invasive biofluid reflecting both local and systemic health status. This observational study aimed to profile the epigenetic signature in the saliva of Obese (OB) and Normal-Weight (NW) pregnant women. Sixteen NW and sixteen OB Caucasian women with singleton spontaneous pregnancies were enrolled. microRNAs were quantified by the OpenArray Platform. The promoter region methylation of Suppressor of Cytokine Signaling 3 (SOCS3) and Transforming Growth Factor Beta 1 (TGF-Beta1) was assessed by pyrosequencing. There were 754 microRNAs evaluated: 20 microRNAs resulted in being differentially expressed between OB and NW. microRNA pathway enrichment analysis showed a significant association with the TGF-Beta signaling pathway (miTALOS) and with fatty acids biosynthesis/metabolism, lysine degradation, and ECM–receptor interaction pathways (DIANA–miRPath). Both SOCS3 and TGF-Beta1 were significantly down-methylated in OB vs. NW. These results help to clarify impaired mechanisms involved in obesity and pave the way for the understanding of specific damaged pathways. The characterization of the epigenetic profile in saliva of pregnant women can represent a promising tool for the identification of obesity-related altered mechanisms and of possible biomarkers for early diagnosis and treatment of pregnancy-adverse conditions.
Introduction: Proteinuria assessment is a key test in pregnancy to evaluate renal and systemic well-being. The finding of proteinuria may allow diagnosis and ready intervention for pre-eclampsia and glomerulonephritis, which may compromise a favorable delivery. Moreover, pathological-range isolated proteinuria is a risk factor by itself for adverse outcomes during pregnancy. An appropriate interpretation of pathologic values of proteinuria is therefore of crucial importance. Patient presentation: We present the case of a 33-year-old apparently healthy woman at her first pregnancy who developed a clinically significant proteinuria during the first trimester; we describe the clinical workup and the management of the patient up to delivery. Conclusion: Urine analysis with dipstick or protein-to-creatinine ratio is part of the routine prenatal clinical care during pregnancy. Detection of a pathological proteinuria (>300 mg/24 h or equivalent) should never be underestimated, and timed urine collection is required, as well as a thorough medical examination. The main goal is to exclude pre-eclampsia, whereas the suspect of a primary kidney disease can be managed together with the nephrologist, both for management and treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
