Abstract
This study aimed to profile the clinical progression, demographics, and oxidative status of COVID-19 patients, correlating with disease severity. The study included 143 participants: 93 patients with COVID-19 (28 outpatients, 65 inpatients), and 50 control participants. Thiobarbituric acid reactive substance (TBARS) was used as an oxidative damage marker. Antioxidant activity was assessed via quantification of Vitamin C, sulfhydryl groups, ferric reduction ability of plasma (FRAP), Uric acid (UA), and evaluation of delta-aminolevulinate dehydratase (δ-ALA-D) enzymatic activity. Geriatric patients, especially men, with comorbidities such as obesity and/or chronic diseases were more likely to develop the most severe form of COVID-19. The activity of the δ-ALA-D was lower in inpatients, and there was no significant difference with the outpatient. Antioxidants decreased in COVID-19 groups, while lipid peroxidation increased. FRAP and Vitamin C decreased with evolution of the disease. Oxidative stress could be used as a predictor of worsening clinical condition.

Abstract
This study aimed to investigate the effects of delivery type (normal or caesarean) on the antioxidant and oxidative capacity of colostrum collected shortly after delivery. A total of 61 parturients were included in the study and divided into two groups: those who underwent vaginal delivery (n = 36) and those who underwent elective caesarean section (n = 25). Colostrum samples were collected by manual milking up to 48 h post parturition and analysed for thiol groups (-SH), vitamin C, ferric reducing ability (FRAP), nitrate/nitrite oxides (NOx), and advanced oxidation protein products (AOPP). Colostrum levels of -SH (p = 0.0042), vitamin C (p = 0.0455), and FRAP (p = 0.0374) were significantly lower in the vaginal delivery group. The results suggest that vaginal delivery, compared to caesarean section, is associated with lower levels of antioxidants in colostrum and the mode of delivery plays an important role in the composition of antioxidants in maternal colostrum that help protect newborns from oxidative damage.IMPACT STATEMENTWhat is already known on this subject? Colostrum is the first biological fluid produced by the mother after delivery and is responsible for a child's growth, cognitive development and health. It is known that childbirth can cause oxidative imbalance, and its effects have already been evaluated in maternal and foetal blood, however, there are few studies evaluating the effects of childbirth on colostrum composition.What do the results of this study add? Previously, a study showed that caesarean section caused greater oxidation of colostrum compared to vaginal delivery. Thus, we sought to evaluate other markers (thiol groups, vitamin C, ferric reducing ability, nitrate/nitrite oxides, and advanced oxidation protein products), in a short period of time after delivery, in order to elucidate this still little discussed issue. Unlike the previous one, our study suggests that vaginal delivery, compared to caesarean section, is associated with lower levels of antioxidants in colostrum, which may make it difficult to protect newborns from oxidative damage.What are the implications of these findings for clinical practice and/or further research? Our study suggests that normal delivery can influence the antioxidant composition of maternal colostrum, and it is debateable for future clinical practice to improve eating habits during pregnancy and lactation, in order to strengthen the antioxidant capacity of colostrum and reduce oxidative damage to newborns.

Abstract
INTRODUCTION Oxidative stress is closely related to the pathophysiology of gestation, where the placenta is susceptible to oxidative damage, contributing to the onset of gestational complications. Currently, few studies evaluate the use of oxidative markers for prediction of risk of gestational complications. However, there are some reports that suggest these biomarkers as potential prognostic biomarkers. Therefore, the objective of this study was to compare the biomarkers of oxidative stress from gestations with and without complications, and also evaluate the delta of variation in these markers from the first gestational trimester. MATERIAL AND METHODS A total of 45 pregnant women were evaluated during the three gestational trimesters, of whom 15 developed gestational complications by the end of gestation. The evaluated oxidative damage markers were thiobarbituric acid reactive substances and nitric oxide dosage. Evaluation of the antioxidant system was performed by the quantification of vitamin C, sulfhydryl groups, total antioxidant capacity, plasmatic iron reduction ability, the evaluation of catalase and delta-aminolevulinate dehydratase enzymatic activity. RESULTS According to the results, the markers of oxidative damage are increased, and the antioxidant profile decreased, in the third trimester of complicated pregnancies as compared to uncomplicated pregnancies. Moreover, the delta of variation in both oxidative damage markers and antioxidants was higher in complicated gestations as compared to uncomplicated gestations, thus suggesting a higher oxidative stress in pregnancies with complications. CONCLUSIONS Oxidative stress parameters appear altered in pregnant women with gestational complications. The markers to oxidative stress can be possible biomarkers, helping in understanding mechanisms underlying the associations between complications during pregnancy and various health outcomes.

Abstract
Aims: The objective of this study was to investigate the effect of the type of delivery (vaginal and cesarean) on the activity of the enzyme delta-aminolevulinate dehydratase (δ-ALA-D), which as yet has not been studied, and the markers of oxidative stress.Methods: Seventy-six mothers and their newborns were divided into two groups: normal birth (VD) and elective cesarean section (ECS). Samples of maternal and umbilical cord blood were collected up to 5 min after birth. Thiobarbituric acid reactive substances (TBARS), advanced oxidation protein products (AOPP), protein thiol (P-SH), nonprotein (NP-SH), the ferric reducing ability of plasma (FRAP), total antioxidant capacity (TAC), catalase, and δ-ALA-D enzyme activity were tested.Results: TBARS and AOPP were significantly higher in mothers of the VD group, while P-SH, NP-SH, FRAP and TAC were reduced. In newborns, TBARS and AOPP did not differ between the groups; however, in the VD group, there was a decrease in P-SH, NP-SH, FRAP, TAC, and catalase. The activity of the δ-ALA-D enzyme was decreased in mothers and neonates born by VD.Conclusions: Mothers undergoing VD had higher levels of free radicals and lower antioxidant defenses, while their newborns decreased antioxidant defenses likely to contain the oxidative imbalance. The inhibition of the δ-ALA-D enzyme in this scenario allows its use as a useful marker of oxidative stress in different obstetric settings.

Abstract
The purpose is to determine markers of oxidative stress related to the longer and shorter duration of labor (DOL) of pregnant women in the umbilical cord blood of neonates, not yet studied. Blood samples from the umbilical cord were collected from pregnant women with normal delivery and classified according to DOL in two groups: a group with DOL less than 310 min (n = 33) and a group with DOL greater than or equal to 310 min (n = 35). The oxidative stress parameters were analyzed by the quantification of thiobarbituric acid reactive substances (TBARS), nitrate/nitrite (NOx), protein thiol groups (P-SH) and non-protein (NP-SH), vitamin C and plasma iron reduction capacity (FRAP), in addition to the activity of the enzyme delta-aminolevulinate dehydratase (δ-ALA-D). The activity of the δ-ALA-D enzyme was shown to be decreased in longer DOL, however, the oxidant parameters and antioxidants were higher in the longer DOL, with the exception of NP-SH that was lower. The longer maternal DOL time is related to the alteration of δ-ALA-D enzyme activity and other parameters in neonates, suggesting an increase in the passage of maternal oxidative markers by umbilical cord blood.

Abstract
Pregnancy is characterized by changes in various organs, triggering changes in the use of energy substrates and increased oxygen consumption. In addition, gestation is an oxidative event that can be assessed by the relationship between free radicals and antioxidants produced by the body. Excessive production of free radicals has detrimental effects such as damage to enzymes, carbohydrates, and DNA. Thus, the objective of this study was to evaluate the oxidative status and antioxidant responses throughout pregnancy through a longitudinal study. Reactive oxygen species were analyzed by means of thiobarbituric acid reactive substances and nitric oxide, the antioxidant system through vitamin C, sulfhydryl groups, total antioxidant capacity, and ferric reducing ability of plasma as well as enzymes such as catalase and delta-aminolevulinate-dehydratase in pregnant women in the three gestational trimesters (n = 30). According to the results, the markers of oxidative damage showed significant differences in the different gestational trimesters where they were increased in the second trimester when compared to the first trimester. The antioxidant defenses responded differently in each gestational trimester, suggesting a response pattern to try to combat the damage caused by free radicals, in order to stabilize the increase of oxidative stress caused in the second gestational trimester.
