Placenta accreta is a significant obstetric complication in which the placenta is completely or focally adherent to the myometrium. The worldwide incidence of placenta accreta spectrum (PAS) is increasing day by day, mostly due to the increasing trends in cesarean section rates. The accurate and timely diagnosis of placenta accreta is important to improve the fetomaternal outcome. Although standard ultrasound is a reliable and primary tool for the diagnosis of placenta accreta, the absence of ultrasound findings does not preclude the diagnosis of placenta accreta. Therefore, clinical evaluation of risk factors is equally essential for the prediction of abnormal placental invasion. Pregnant women with a high impression or established diagnosis of placenta accreta should be managed by a multidisciplinary team in a specialist center. Traditionally, PAS has been managed by an emergency obstetric hysterectomy. Previously, few studies suggested a satisfactory success rate of conservative management in well-chosen cases, whereas few studies recommended delayed hysterectomy to reduce the amount of bleeding. The continuously increasing trends of PAS and the challenges for its routine management are the main motives behind this literature review.
Background: Obesity, inflammation and alterations in matrix metalloproteinase-9 (MMP-9) and nitric oxide (NO) levels are involved in the development of polycystic ovary syndrome (PCOS). Objective: To investigate the relationship of MMP-9, NO and interleukin-10 (IL-10) with the increase in body mass index (BMI) in women with PCOS. Materials and Methods: Sixty two infertile PCOS women were included in the study. Serum levels of NO, IL-10 and MMP-9 were assessed in the women with increase in BMI. Results: MMP-9 was significantly increased (p = 0.029) and IL-10 (p = 0.015) was significantly reduced in obese PCOS subjects compared to those with lesser BMI. MMP- 9 levels positively correlated with the duration of infertility (r = 0.253, p = 0.047) and negatively correlated with NO levels (r = - 0.259, p = 0.042). A significant negative correlation between the interleukin-10 levels and the BMI (r = - 0.272, p = 0.033) was also found in the PCOS subjects. Conclusion: MMP-9 levels are increased in obese PCOS women and it is associated with NO levels and the duration of infertility. Key words: Body mass index, Interleukin-10, Nitric oxide, Matrix metalloproteinase-9.
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.
