Article Synopsis
  • Brazil had 37 million COVID-19 cases by January 2023, but vaccination reduced mortality; however, long-term impacts, such as Post-Covid Condition (PCC), remain a concern for health professionals.
  • Longitudinal studies are vital for understanding the chronic health consequences of COVID-19 and how it affects patients' quality of life over time.
  • The study identified that women and previously hospitalized patients are more likely to experience PCC, highlighting the need for public health strategies to address the ongoing challenges posed by the virus.

Background: Metabolic syndrome is a multifactorial disease, and the gut microbiota may play a role in its pathogenesis. Obesity, especially abdominal obesity, is associated with insulin resistance, often increasing the risk of type two diabetes mellitus, vascular endothelial dysfunction, an abnormal lipid profile, hypertension, and vascular inflammation, all of which promote the development of atherosclerotic cardiovascular disease.

Aim: To evaluate the outcomes of fecal microbiota transplantation (FMT) in patients with metabolic syndrome.

Several perturbations in the number of peripheral blood leukocytes, such as neutrophilia and lymphopenia associated with Coronavirus disease 2019 (COVID-19) severity, point to systemic molecular cell cycle alterations during severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. However, the landscape of cell cycle alterations in COVID-19 remains primarily unexplored. Here, we performed an integrative systems immunology analysis of publicly available proteome and transcriptome data to characterize global changes in the cell cycle signature of COVID-19 patients.

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.

Background: Obesity and comorbidities onset encompass gut dysbiosis, altered intestinal permeability, and endotoxemia. Treatments that target gut dysbiosis can cope with obesity and nonalcoholic fatty liver disease (NAFLD) management. Peroxisome proliferator-activated receptor (PPAR)-alpha activation and dipeptidyl-peptidase-4 (DPP-4) inhibition alleviate NAFLD, but the mechanism may involve gut microbiota modulation and merits further investigation.

The aim of this study was to investigate the clinical and oxidative profile, including the activity of the enzyme delta-aminolevulinate dehydratase (δ-ALA-D), in women who acquired toxoplasmosis during pregnancy and used the triple regimen (sulfadiazine + pyrimethamine + folinic acid [SPFA]) as treatment. These parameters have not been evaluated in pregnant women with toxoplasmosis who used the triple regimen. A total of 53 pregnant women were recruited and divided into two groups: control (C; n = 27) and acute toxoplasmosis (AT; n = 26).

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 ( = 33) and a group with DOL greater than or equal to 310 min ( = 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).

Heart failure (HF) is a clinical syndrome that involves structural changes in the heart, leading to a decrease in cardiac output, mainly caused by myocardial infarction (MI), which is the most common form of cardiovascular disease worldwide. Clinical evaluation remains the most accurate diagnostic method for ischemic HF, since the known biomarkers have high cost, are difficult to use for early diagnosis, and have low specificity. This often leads to late diagnosis since only ~ 25% symptoms of HF appear after MI.

January 2019

Postgraduate Program in Pharmaceutical Sciences, Department of Clinical and Toxicology Analysis, Center of Healthy Sciences, Federal University of Santa Maria (UFSM), Santa Maria 97105-900, Brazil.

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.

Preeclampsia is an important pregnancy-specific multisystem disorder characterized by the onset of hypertension and proteinuria. It is of unknown etiology and involves serious risks for the pregnant women and fetus. One of the main factors involved in the pathophysiology of preeclampsia is oxidative stress, where excess free radicals produce harmful effects, including damage to macromolecules such as lipids, proteins and DNA.

Int J Environ Res Public Health

May 2016

Postgraduate Program in Pharmaceutical Sciences, Department of Clinical and Toxicology Analysis, Center of Healthy Sciences, Federal University of Santa Maria (UFSM), Santa Maria 97105-900, Brazil.

An oxidative burst occurs during pregnancy due to the large consumption of oxygen in the tissues and an increase in metabolic demands in response to maternal physiological changes and fetal growth. This study aimed to determine the oxidative profile and activity of δ-aminolevulinate dehydratase (δ-ALA-D) in pregnant women who received iron supplementation. Oxidative stress parameters were evaluated in 25 pregnant women with iron supplementation, 25 pregnant women without supplementation and 25 non-pregnant women.
