Evaluation of oxidative stress level: reactive oxygen species, reduced glutathione, and D-dimer in patients hospitalized due to COVID-19.

Elevated D-dimer levels at hospital admission may also indicate a higher likelihood of progressing to a severe or critical state. This study aimed to assess reactive oxygen species (ROS), non-enzymatic antioxidant reduced glutathione (GSH), and D-dimer levels in COVID-19 patients upon admission, examining their association with mortality outcomes. Data was collected from the medical records of 170 patients hospitalized in a referral hospital unit between March 2020 and December 2021. Patients were divided into two groups: the ward bed group (n = 87), comprising 51% with moderate clinical conditions, and the intensive care unit (ICU) group (n = 83), comprising 49% with severe conditions. The mean age was 59.4 years, with a male predominance of 52.4%. The overall death rate was 43%, with 30.6% in the moderate group and 69.4% in the severe group. The average time from symptom onset to hospitalization was 6.42 days. Results showed that non-survivors had high D-dimer and ROS counts, longer ICU stays, and worse saturation levels at admission. In conclusion, elevated ROS and D-dimer levels may contribute to worse outcomes in critically ill patients, potentially serving as specific and sensitive predictors of poor outcomes upon admission.

Influence of pesticide exposure on farmers' cognition: A systematic review.

Objectives: Pesticide application has become necessary to increase crop productivity and reduce losses. However, the use of these products can produce toxic effects. Farmers are individuals occupationally exposed to pesticides, thus subject to associated diseases as well as cognitive impairment. However, this relation is not well established in the literature, requiring further investigation. To assess the potential association between farmers' pesticide exposure and cognitive impairment, we followed the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, considering participants, interventions, comparators, outcomes, and study strategies. Materials and Methods: This study included articles published between 2000 and 2021 on the Scopus, Web of Science, ScienceDirect, and PubMed databases, retrieved by the terms "pesticides and cognition" and "pesticides and memory." Results: In total, ten studies fit the established criteria and were included in the sample. All had farmers occupationally exposed to pesticides in their sample and only one study dispensed with a control group. Of the neurobehavioral tests, four studies used mini-mental state examination, six neurobehavioral core test batteries (tests recognized in the area), and the remaining, other tests. We observed that 90% of articles found an association between cognitive impairment and pesticide exposure. Overall, five studies measured the activity of cholinesterases in their sample, of which three found significant differences between groups, confirming intoxication in those exposed. Conclusion: Despite the limited number of trials, we found scientific evidence to support the existence of adverse effects of pesticides on farmers' cognition. We recommend that future studies research similar projects, expanding knowledge on the subject.

Occupational exposure to pesticides dysregulates systemic Th1/Th2/Th17 cytokines and correlates with poor clinical outcomes in breast cancer patients.

Pesticides are compounds known to cause immunetoxicity in exposed individuals, which have a potential to substantially modify the prognosis of pathologies dependent on an efficient immune response, such as breast cancer. In this context, we examined the circulating cytokine profile of Th1/Th2/Th17 patterns in women occupationally exposed to pesticides and their correlation with worse prognostic outcomes. Peripheral blood samples were collected from 187 rural working women with breast cancer, occupationally exposed or not to pesticides, to quantify the levels of cytokines IL-1ß, IL-12, IL-4, IL-17-A, and TNF -α. Data on the disease profile and clinical outcomes were collected through medical follow-up. IL-12 was reduced in exposed women with tumors larger than 2 cm and in those with lymph node metastases. Significantly reduced levels of IL-17A were observed in exposed patients with Luminal B subtype tumors, with high ki67 proliferation rates, high histological grade, and positive for the progesterone receptor. Reduced IL-4 was also seen in exposed women with lymph node invasion. Our data show that occupational exposure to pesticides induces significant changes in the levels of cytokines necessary for tumor control and correlates with poor prognosis clinical outcomes in breast cancer.

Evaluation of the effects of metformin on antioxidant biomarkers and mineral levels in patients with type II diabetes mellitus: A cross-sectional study.

Diabetes mellitus (DM) and arterial hypertension are considered serious public health problems. Several studies have shown that oxidative stress is usually related to the onset of DM and hypertension, as well their associated complications. Moreover, the levels of some minerals are closely related to the pathophysiology of these diseases. Thus, in this study we aimed to evaluate the effect of metformin on the redox profile and mineral levels in the serum of patients with DM type 2 and hypertension. We also tested the effect of metformin on the viability and redox profile of peripheral blood mononuclear cells (PBMCs) for 24 h. As expected, we found that patients with type 2 DM and hypertension + type 2 DM had higher fasting glucose and triglyceride levels. As groundbreaking research, we found that both patients DM type 2 and Hypertension + DM type 2 had reduced myeloperoxidase (MPO) activity. On the other hand, the levels of total thiols (PSH) and vitamin C were increased. There was no statistical significance for the alterations in mineral levels. In addition, metformin treatment had no cytotoxic effect on PBMCs. Similarly, in patients of both groups, MPO activity was reduced and PSH levels were increased in PBMCs. We have shown that metformin is a drug with a protective effect in patients with DM type 2 against oxidative stress by reducing MPO activity and improving the levels of PSH and antioxidant defenders such as vitamin C. The results of in vitro assays support the antioxidant effect of metformin. Furthermore, we suggest studies to assess the biochemical mechanisms of metformin and how it can be used in a pharmacological therapeutic perspective against oxidative damage.

Gummies candy enriched with Konjac glucomannan reduces hunger intensity and waist circumference of overweight individuals.

Konjac glucomannan (KGM) is a herbal medicine with benefits in appetite control, body weight and biochemical parameters in overweight individuals. The objective of our work was to evaluate the effect of the consumption of gummy candy enriched with KGM on appetite, to evaluate anthropometric data, biochemical and oxidative stress markers in overweight individuals. Forty-two participants aged 18 to 45 years completed our randomized, double-blind, placebo-controlled clinical trial. Participants were randomly assigned to consume for fourteen days, 2 candies per day, containing 250 mg of KGM or identical-looking placebo candy with 250 mg of flaxseed meal, shortly after breakfast and dinner. As a result, we observed that there was a reduction in waist circumference and in the intensity of hunger/satisfaction of the participants who consumed KGM for fourteen days, and we believe that a longer consumption time as well as an increase dose of KGM contribute to even more satisfactory body results.

Effects of Intuitive Eating on the Quality of Life and Wellbeing of Yoga Practitioners, Physical Activity Practitioners and Sedentary Individuals.

This study is a comparative analysis of the effects of intuitive eating and correlations with quality of life and wellbeing in Yoga practitioners, physical activity practitioners and sedentary individuals. The study involved 204 participants, comprising 66 Yoga practitioners, 74 physical activity practitioners and 64 sedentary individuals, between the ages of 20 and 59, who were resident in Brazil at the time of the study. Quantitative research was conducted through Facebook and the application questionnaires via Google Forms to measure intuitive eating, food consumption, quality of life, stress level, satisfaction with body image and level of mindfulness. The study found that while intuitive eating did not differ between Yoga practitioners and physical activity practitioners, both showed greater adoption of intuitive eating as compared to inactive individuals. Still, Yoga practitioners had better confidence in their physiological signs of hunger and satiety, as well as better eating behavior, quality of life, satisfaction with body image, healthy body weight, and stress-related emotional regulation, as compared to the other groups. In addition, there was a positive correlation between intuitive eating and quality of life, body esteem, mindfulness and eating behaviors that discouraged eating in response to external or psychological influences, and a negative correlation to stress and weight gain. This study finds that physical exercise, in particular the practice of Yoga, is linked to the promotion of better intuitive eating behavior as well as better quality of life and wellbeing.

Effect of polycaprolactone nanocapsules loaded with essential oils on biofilm formation by Staphylococcus aureus strains isolated from bovine mastitis cases

Abstract Bovine infectious mastitis is largely resistant to antibacterial treatment, mainly due to mechanisms of bacterial resistance in the biofilms formed by Staphylococcus aureus. Melaleuca (MEO) and citronella essential oils (CEO) are promising agents for reducing or eliminating biofilms. Free melaleuca oil presented a medium Minimum Inhibitory Concentration (MIC) of 0.625% and a Minimum Bactericidal Concentration (MBC) of 1.250%, while free citronella oil showed medium MIC and MBC of 0.313%. Thus, free CEO and MEO demonstrate bacteriostatic and bactericidal potential. We generated polymeric nanocapsules containing MEO or CEO and evaluated their efficacy at reducing biofilms formed by S. aureus. Glass and polypropylene spheres were used as test surfaces. To compare the responses of free and encapsulated oils, strains were submitted to 10 different procedures, using free and nanoencapsulated essential oils (EOs) in vitro. We observed no biofilm reduction by MEO, free or nanoencapsulated. However, CEO nanocapsules reduced biofilm formation on glass (p=0.03) and showed a tendency to diminish biofilms on polypropylene (p=0.051). Despite nanoencapsulated CEO reducing biofilms in vitro, the formulation could be improved to modify the CEO component polarity and, including MEO, to obtain more interactions with surfaces and the biofilm matrix

In vitro antioxidant extracts evaluation from the residue of the Hevea brasiliensis seed.

The antioxidants used in the food industry are essential to inhibit the formation of free radicals, preserving the existing properties in the different matrices. However, the insecurity of the synthetic antioxidants regarding human health propels search for natural substrates with potential antioxidant activity as an alternative to synthetic compounds. In this way, the work had as objective obtaining extracts from the seed pomace of the Hevea brasiliensis (rubber tree), relating the contents of flavonoids and total phenols in the application as an antioxidant. The methodology consisted of the extraction using four solvents, varying extractive methods, time, and seed concentrations. The antioxidant activity in vitro was evaluated by capturing the DPPH (2,2-diphenyl-1-picryl-hydrazil) radical. The optimized results demonstrate that the aqueous extracts produced in the Soxhlet in the concentrations of 85 g L-1 and retention time of 4 h reached 37.73 ± 1.69% in the antioxidant tests of the free radical DPPH capture, 1405.15 mg EAC 100 g-1 in the quantification of phenolic compounds and 223.34 mg 100 g-1 of total flavonoids. Thus, this work may contribute to the realization of studies and future research for characterization and identification concerning which phenolic compounds and flavonoids attribute the antioxidant characteristic to the extracts produced, enabling the discovery of products with high added value in the production chain. In addition, because the water used as a solvent showed greater antioxidant potential between the extracts, the non-toxic and environmentally friendly character is highlighted, allowing a wide variety of applications in the food industry.

Antioxidant Evaluation of Extracts of Pecan NutShell (Carya illinoensis) in Soybean Biodiesel B100.

Biodiesel is subject to radical reactions that promote degradation. To decrease the speed of these degradation reactions and increase oxidative stability, either natural or synthetic antioxidants are added to biodiesel. Thus, the objective of this study is to evaluate the effect of extracts of pecan nutshell (Carya illinoensis) as natural antioxidants derived from biomass using water, ethanol, and methanol/water (50/50) as a solvent for extraction. The addition of these antioxidants is performed during the soybean biodiesel washing process in an unconventional manner. The results obtained are statistically analyzed and compared to the control. The induction time (IT) for the biodiesel samples washed with ethanolic extract of pecan nutshell (5 g L-1), aqueous extract of pecan nutshell (12 g L-1) and methanol/water extract of pecan nutshell (12 g L-1), are, respectively, 9.46, 7.60, 7.43 h. The activation energy and the storage time of the biodiesel samples washed with the extracts are also studied. The order of reaction of the oxidation kinetics of biodiesel is first order.

Características físico-químicas dos tubérculos da Tropaeolum pentaphyllum Lam / Physico-chemical characteristics of tubers of Tropaeolum pentaphyllum Lam

A Tropaeolum pentaphyllum Lam é uma Planta Alimentícia Não Convencional (PANC) nativa do Brasil, que está em crescente estudo. O objetivo deste trabalho foi avaliar a composição físico-química, o pH e cor da polpa da batata. Observou-se que a umidade (79,32 %), proteína (2,33%) e cinzas (0,93%), apresentaram-se semelhantes à T. pentaphyllum Lam avaliadas em outros estudos. Já os teores de carboidratos (13,02%), valor energético (82,19%) e lipídeos (3,82%) apresentaram-se superiores e de fibras (1,78%) inferiores a vegetais da mesma espécie. Além disso, a planta mostrou-se ácida, luminosa e com coloração tendendo ao vermelho e ao amarelo. Assim, percebe-se que a batata pode ser considerada um complemento alimentar pela sua composição nutricional e que é necessário a realização de mais estudos, a fim de aprimorar o conhecimento sobre a mesma.

BACKGROUND: Crohn's disease is an idiopathic chronic inflammatory disease. It is classified as an inflammatory bowel disease. Crohn's disease can change patient quality of life, especially during flares. Crohn's disease has been associated with symptoms of anxiety and depression, because the clinical symptoms have a high impact on quality of life. OBJECTIVE: To investigate the prevalence of symptoms of anxiety and depression in Brazilian patients diagnosed with Crohn's disease, as well as their quality of life. METHODS: A total of 110 Brazilian patients aged 21-59 years, both genders, with Crohn's disease were included. The data were collected through questionnaires. The Hospital Anxiety and Depression Scale (HADS) was used to assess anxiety and depression symptoms. Quality of life was evaluated using the Inflammatory Bowel Disease Questionnaire. Data were analyzed by ANOVA, followed by the Duncan post-hoc test and the multiple linear regression test. RESULTS: Of the total, 61.7% of participants reported symptoms of anxiety or depression or both. Regarding quality of life, the majority (43.6%) were classified as "regular" and the minority (3.6%) as "excellent". Multiple linear regression showed that worse quality of life correlated with greater presence of anxiety and depression symptoms (<0.001). CONCLUSION: Crohn's disease has considerable impact on quality of life and contributes to the appearance of anxiety and/or depression symptoms.

Effects of Fish and Grape Seed Oils as Core of Haloperidol-Loaded Nanocapsules on Oral Dyskinesia in Rats.

Haloperidol is a widely used antipsychotic, despite the severe motor side effects associated with its chronic use. This study was carried out to compare oral dyskinesia induced by different formulations of haloperidol-loaded nanocapsules containing caprylic/capric triglycerides, fish oil or grape seed oil (GSO) as core, as well as free haloperidol. Haloperidol-loaded lipid-core nanocapsules formulations were prepared, physicochemical characterized and administered (0.5 mg kg-1-ip) to rats for 28 days. Oral dyskinesia was evaluated acutely and subchronically and after that cell viability and free radical generation in cortex and substantia nigra. All formulations presented satisfactory physicochemical parameters. Acutely, all formulations were able to prevent oral dyskinesia development in comparison to free haloperidol, except haloperidol-loaded nanocapsules containing GSO, whose effect was only partial. After subchronic treatment, all haloperidol-loaded nanocapsules formulations prevented oral dyskinesia in relation to free drug. Also, haloperidol-loaded nanocapsules containing fish oil and GSO were more effective than caprylic/capric triglycerides nanocapsules and free haloperidol in cell viability preservation and control of free radical generation. Our findings showed that fish oil formulation may be considered as the best formulation of haloperidol-loaded lipid-core nanocapsules, being able to prevent motor side effects associated with chronic use of antipsychotic drugs, as haloperidol.

Toxicological aspects of trans fat consumption over two sequential generations of rats: Oxidative damage and preference for amphetamine.

Chronic consumption of processed food causes structural changes in membrane phospholipids, affecting brain neurotransmission. Here we evaluated noxious influences of dietary fats over two generations of rats on amphetamine (AMPH)-conditioned place preference (CPP). Female rats received soybean oil (SO, rich in n-6 fatty acids (FA)), fish oil (FO, rich in n-3 FA) and hydrogenated vegetable fat (HVF, rich in trans fatty acids (TFA)) for two successive generations. Male pups from the 2nd generation were maintained on the same supplementation until 41 days of age, when they were conditioned with AMPH in CPP. While the FO group showed higher incorporation of n-3 polyunsaturated-FA (PUFA) in cortex/hippocampus, the HVF group showed TFA incorporation in these same brain areas. The SO and HVF groups showed AMPH-preference and anxiety-like symptoms during abstinence. Higher levels of protein carbonyl (PC) and lower levels of non-protein thiols (NPSH) were observed in cortex/hippocampus of the HVF group, indicating antioxidant defense system impairment. In contrast, the FO group showed no drug-preference and lower PC levels in cortex. Cortical PC was positively correlated with n-6/n-3 PUFA ratio, locomotion and anxiety-like behavior, and hippocampal PC was positively correlated with AMPH-preference, reinforcing connections between oxidative damage and AMPH-induced preference/abstinence behaviors. As brain incorporation of trans and n-6 PUFA modifies its physiological functions, it may facilitate drug addiction.

Haloperidol-loaded polysorbate-coated polymeric nanocapsules decrease its adverse motor side effects and oxidative stress markers in rats.

Haloperidol is the most widely used antipsychotic drug in the treatment of psychiatric disorders. Despite its satisfactory therapeutic effect, its chronic use is related to severe motor side effects. Here, we investigate the incidence of motor side effects of haloperidol-loaded nanocapsules when compared to free haloperidol and the relation with oxidative stress (OS) development. Both vehicle (B-NcFO) and haloperidol loaded polysorbate-coated nanocapsules suspension (H-NcFO) prepared with fish oil as core showed uniform and rounded particles, nanometric size, negative zeta potential, low polydispersity indices and high encapsulation efficiency. Wistar rats received a single dose of free haloperidol (FH), B-NcFO or H-NcFO (0.2 mg/kg ip) and were submitted to acute motor side effects evaluation 1 h after the injection. Lower catalepsy time and oral dyskinesia were observed in H-NcFO-treated group than in FH group; however, both formulations decreased animals' locomotor activity. In a experiment performed subchronically, rats injected daily with H-NcFO (0.2 mg/kg-ip) for 28 days showed decreased oral dyskinesia frequency and catalepsy time and no impairment on locomotor activity as compared to FH group (0.2 mg/kg-ip). FH group showed higher OS, as observed by increased lipid peroxidation and reduced glutathione levels and catalase activity in extrapyramidal region. Our findings showed that nanocapsules may be an efficient form to prevent or minimize haloperidol motor side effects, which are related to OS development, ameliorating psychiatric patients' quality of life.

Short term dietary fish oil supplementation improves motor deficiencies related to reserpine-induced parkinsonism in rats.

Fish oil (FO) supplementation could cause an increase in the concentration of plasmatic free fatty acids and, consequently, could compete with pro-inflammatory arachidonic acid (ARA) derived from brain biomembranes metabolism in the cerebrospinal fluid. Essential fatty acids (EFA) (n-3) have been reported by their antioxidant and neuroprotective properties, and therefore the influence of the FO supplementation on the reserpine-induced motor disorders was studied. Wistar rats were orally treated with FO solution for 5 days, and co-treated with reserpine (R; 1 mg/kg/mL) or its vehicle for 3 days (every other day). Reserpine-induced orofacial dyskinesia and catalepsy (P < 0.05) were prevented by FO (P < 0.05). Biochemical evaluations showed that reserpine treatment increased the lipid peroxidation in the cortex and striatum (P < 0.05), while the FO supplementation prevented this oxidative effect in both brain regions (P < 0.05). Our results showed the protective role of FO in the brain lipid membranes, reinforcing the beneficial effect of n-3 fatty acids in the prevention of degenerative and motor disorders.

Effects of omega-3 essential fatty acids (omega-3 EFAs) on motor disorders and memory dysfunction typical neuroleptic-induced: behavioral and biochemical parameter.

The effects of fish oil supplementation on motor disorders, memory dysfunction, and lipid peroxidation (LP) induced by typical neuroleptics were studied. Wistar rats received a suspension prepared with fish oil containing omega-3 fatty acids, water, and Tween 80 (1%) in the place of drinking water (FO group) or vehicle (C group) for 8 weeks. After 4 weeks of treatment, half of the animals of both groups were treated with haloperidol (H and FO + H groups; experiment 1), fluphenazine (F and FO + F groups; experiment 2), or vehicle (C group), administered once a week (12 mg/kg/im) for 4 weeks, maintaining the treatment with FO. Extrapyramidal motor disorders by haloperidol and fluphenazine were observed by an increase in vacuous chewing movements and catalepsy (P < 0.05). These effects were reduced by FO treatment (P < 0.05). Both neuroleptics displayed impairment in memory retention observed by latency time to find the original location of platform in water-maze task, after 4 days of training performed in the last treatment week. This effect was reduced by FO (P < 0.05) to both haloperidol and fluphenazine treatments. Haloperidol increased the LP in plasma and hippocampus, and these effects were decreased by FO treatment (P < 0.05). Fluphenazine increased the LP in plasma and substantia nigra, which were completely decreased by FO treatment (P < 0.05). The FO decreased the motor disorders, memory dysfunction, and oxidative damage typical neuroleptic-induced. Our results indicate that FO exhibits a neuroprotector role useful on diseases related to oxidative damages, and may be considered in the prevention of motor and memory side effects induced by the antipsychotic treatment.
