Serum ceruloplasmin level may have significant role as the markers of oxidative stress in pre-eclampsia especially when used in combination with uric acid levels.
Background The aim of this study was to evaluate the markers of oxidative stress (OS), as well as the magnesium (Mg) concentration, pregnancy-associated plasma protein A (PAPP-A) and human chorionic gonadotropin (β-hCG) values in patients with previous recurrent miscarriages, with the purpose of comparing the level of OS with normal pregnancy. Methods The study was conducted as a prospective study, which included a total of 95 pregnant women divided into two groups. In the study group (n = 35), there were women with at least three consecutive previous miscarriages. The control group (n = 60) consisted of healthy pregnant women without previous miscarriages and complications in pregnancy. Blood samples were taken between the 11th and 14th weeks of gestation, and the values of superoxide dismutase (SOD-1), glutathione peroxidase (GSH-Px) and total antioxidant status (TAS) in the serum, as well as the Mg concentration, PAPP-A and β-hCG values were determined. Results The values of SOD and GHS-Px were statistically higher in the study group, while the values of TAS were statistically significantly higher in the control group. The values of the Mg concentration were statistically significantly higher in the control group, while the values of β-hCG were statistically significantly higher in the study group. When the study group was divided into subgroups according to the outcome of pregnancy, there were statistical differences in the level of GSH-Px, SOD between miscarriages and the term delivery group, as well as in the Mg concentration between miscarriages and the term delivery group and between the term and preterm delivery groups. Higher values of SOD and GHS-Px, and lower values of TAS and Mg concentration could be used as markers for the prediction of spontaneous miscarriages. Conclusions The results of this research indicated higher OS and exhaustion of antioxidant mechanisms in early pregnancy in a group with recurrent miscarriages. Also, lower values of serum Mg concentration could be one of the markers for the prediction of spontaneous miscarriages.
Many adolescents worldwide have the problem of meeting recommended nightly sleep hours. The causes of sleep disturbance are multifactorial, but interest in food’s effect on sleep has dramatically increased lately. In this study, we investigated the association between regular energy drink (ED) intake (weekly or more frequent) and sufficient sleep (SS) (≥8 h) in adolescents. Additional objectives were to examine the relationship between health-related behaviors and SS, stratified by gender. A population-based cross-sectional study was conducted during the 2019/2020 school year from 12 schools in Belgrade. There were 1287 students aged 15 to 19 who participated (37.4% male). We used a modified version of the food frequency questionnaire adapted for Serbian adolescents. Logistic regression revealed that regular ED consumption was an independent risk factor negatively related to SS in both sexes. Additionally, daily vegetable and water intake (≥2 L) showed a positive correlation with SS in boys, while in girls, the odds of realizing SS decreased with statements of sedative use. In conclusion, we show that ED intake is negatively associated with SS in both sexes; daily vegetable and water intake (≥2 L) may raise the odds of SS in boys, while sedative use may decrease the chances of SS in girls.
Our study indicates that the pregnancy complicated with bacterial vaginosis ends much earlier than the pregnancy without it. Also, higher levels of biochemical markers of inflammation in the serum in the study group, similarly to results of other studies, suggest that pathophysiological processes responsible for preterm delivery can begin very early in pregnancy.
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.
