Unlabelled: SIRTs were demonstrated to play an important role in inflammatory, degenerative, and metabolic alterations, constituting the background of the central nervous system. Thus, they seem to be an appropriate object of investigation (as potential biomarkers of disease activity and/or novel therapeutic targets) in multiple sclerosis (MS), which has a complex etiology that comprises a cross-talk between all these processes. The aim of this study was to evaluate the levels of SIRT1 and SIRT2 in the serum of patients with the relapsing-remitting type of MS (RRMS), as well as their relationships with various aspects of MS-related disability.

We investigated the effects of tobacco smoke exposure and abnormal body weight on selected peptide hormones and their association with metabolic and hormonal disorders in women with polycystic ovary syndrome (PCOS). The study group included 88 women with PCOS and 28 women without the disease. In women with PCOS, chemerin, lipocalin, and apelin concentrations were influenced by overweight and obesity status, with the highest concentrations observed in those with a body mass index (BMI) ≥ 30.

This prospective cohort study was conducted to evaluate the association between women's satisfaction with breastfeeding at 1 month post-partum and the risk of exclusive breastfeeding (EBF) interruption before 6 months. 287 mother-infant dyads randomly selected from two maternity hospitals were followed from birth to 24 months of infant's age. Women's satisfaction with breastfeeding was assessed using the Maternal Breastfeeding Evaluation Scale (MBFES) at 1 month.

Objectives: The nitrogen-containing xenobiotics, such as nitrates and acrylamide may potentially influence systemic redox status and contribute to the generation of oxidative stress (OS) in the human body, but there is still a lack of studies that would evaluate the various parameters assessing the oxidative-antioxidant balance. The aim of this study was to evaluate the exposure to nitrates and acrylamide derived from daily diet and to analyze the impact of these nitrate-containing xenobiotics on the parameters of systemic redox status in healthy young adults.

Material And Methods: To assess nitrate and acrylamide intake in the study population, a semi-quantitative food frequency questionnaire was used.

The aim of this study was to evaluate oxidative stress parameters, specifically the concentration of advanced oxidation protein products (AOPP) and ferric-reducing antioxidant power (FRAP), in the serum of patients with relapsing-remitting multiple sclerosis (RRMS). We also analyzed the relationships between each parameter and selected clinical/laboratory multiple-sclerosis-related parameters. The study group comprised 204 patients with RRMS and 29 healthy, age-matched controls.

Silent information regulators, sirtuins (SIRTs), are a family of enzymes which take part in major posttranslational modifications of proteins and contribute to multiple cellular processes, including metabolic and energetic transformations, as well as regulation of the cell cycle. Recently, SIRTs have gained increased attention as the object of research because of their multidirectional activity and possible role in the complex pathomechanisms underlying human diseases. The aim of this study was to review a current literature evidence of SIRTs' role in the physiology and pathology of the central nervous system (CNS).

We investigated selected pro/antioxidant parameters in a group of women with polycystic ovary syndrome (PCOS) divided according to age, body mass index (BMI), waist-to-hip ratio (WHR), homeostatic model assessment for insulin resistance (HOMA-IR) and quantitative insulin sensitivity check index (Quicki). We chose oxidized low-density lipoproteins (oxLDL-C) as a marker of oxidative stress and the ferric reducing ability of plasma (FRAP) as a marker of antioxidant status. In women with PCOS, the values of BMI, WHR, age and concentration of glucose significantly affected oxLDL-C concentration and FRAP values.

Superoxide dismutase (SOD) is a crucial antioxidant enzyme involved in the antioxidant pathway during both normal cellular metabolism and different pathologic processes. We investigated the activity of the copper (Cu)-zinc (Zn) SOD1 as well as the level of Cu and Zn in the serum of women with polycystic ovary syndrome (PCOS) and control group. Moreover, the prevalence of rs2070424 gene polymorphism of the enzyme in the course of PCOS was evaluated.

We investigated the relationship between selected body composition (BC) parameters and included 55 women diagnosed with PCOS and 29 women in which PCOS was excluded. Hormone concentration and BC parameters were assessed during hospitalization. Women with PCOS had higher concentration of luteinizing hormones, total testosterone, androstenedione, and Anti-Müllerian hormones compared to women that were not diagnosed with PCOS.

We aimed to evaluate the relationship between selected serum sex hormones and lipid profiles in a group of women with polycystic ovary syndrome (PCOS) dividing according to four phenotypes, value of body mass index (BMI), and presence of hyperlipidemia. The study included 606 Caucasian women. Lipids and selected hormones were estimated using commercially available procedures during hospitalization in 2017.

Objective: Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disorders, which may contribute to the development of cardiovascular diseases. The aim of our study was to evaluate the association between of 24-hour ambulatory blood pressure measurement (ABPM) and selected biochemical and anthropometric parameters in women with PCOS.

Patients And Methods: The study involved 153 Polish, Caucasian women with PCOS hospitalized in the Department of Endocrinology Gynecology from January 2018 to March 2020.

This study aimed to evaluate the concentration of proprotein convertase subtilisin/kexin type-9 (PCSK9) and the activities of paraoxonase 1 in women with and without polycystic ovary syndrome (PCOS). We found significant higher PCSK9, whereas lower high-density lipoprotein concentration in the serum of women with PCOS when compared to the group without PCOS. Also paraoxonase 1 activities were significantly different between women with PCOS than without PCOS.

Background: Due to the multiple health benefits of breastfeeding, it is essential to identify factors that may negatively interfere with this healthy practice. Among such factors are postpartum depression (PPD) and maternal satisfaction with breastfeeding. The objective of this study was to evaluate the association between maternal satisfaction with breastfeeding and symptoms of PPD in the first month after childbirth.

Article Synopsis
  • This study explores maternal satisfaction with breastfeeding among women in Porto Alegre, Brazil, within the first month after giving birth, as previous research primarily focused on breastfeeding duration rather than the quality of the experience.
  • The research involved 287 women who were surveyed about their breastfeeding satisfaction using the validated Maternal Breastfeeding Evaluation Scale (MBFES) and analyzed factors influencing this satisfaction.
  • Results showed high satisfaction levels, with median scores indicating that women of brown and black skin color had significantly higher satisfaction rates compared to other groups.
