Evid Based Complement Alternat Med 2021 6;2021:5584965. Epub 2021 Dec 6.

Departamento de Biofísica e Fisiologia, Universidade Federal do Piauí, CEP 64049-550, Teresina, PI, Brazil.

This study aimed to evaluate the effects of the treatment with bacuri seed butter (BB) on body weight, growth, body mass index, lipid profile, atherosclerotic indices, and liver function in dyslipidemic hamsters. Freshly weaned, male hamsters were divided into four groups: (1) normal group (NG)-maintained with standard chow (AIN-93G); (2) dyslipidemia group (DG)-maintained with hyperlipidemic chow (AIN-93G modified) throughout the follow-up period; (3) bacuri seed butter 25 mg/kg/day (BB-25); and (4) bacuri seed butter 50 mg/kg/day (BB-50). BB groups (25 and 50 mg/kg/day) were also maintained with hyperlipidemic chow throughout the follow-up period, and the treatment started after 21 days receiving a hyperlipidemic diet to induce hypercholesterolemia and maintained for 28 days. No significant differences in triglycerides and total cholesterol were observed for BB-25 and BB-50 groups when compared with NG and DG groups. On the contrary, BB-25 and BB-50 induced both increase of HDL-c (51.40 ± 1.69 and 51.00 ± 2.34, respectively) and decrease of LDL-c (103.80 ± 6.87 and 100.50 ± 3.95, respectively) when compared with DG (41.00 ± 2.94 and 132.70 ± 9.41, respectively). In addition, BB promoted a reduction in the risk of atherosclerotic disease by decreasing ( < 0.05) the atherogenic index, coronary artery risk index, and LDL/CT ratio ( < 0.05) and increasing HDL/CT ratio. On the contrary, no changes were observed in total cholesterol and triglyceride levels or in body weight, growth, body mass index, or liver function parameters. Thus, bacuri seed butter at doses of 25 and 50 mg/kg/day has positive repercussions on the lipid profile, more precisely on plasma HDL-c and LDL-c, and additionally promotes reduction in the risk of atherosclerosis in hamsters.

The increase in the input of ultra-processed ingredients in the food of children and adolescents is related to the development of noncommunicable diseases such as dyslipidemia. The scope of this study was to conduct a systematic review of the literature on the relationship of consumption of ultra-processed foods in the lipid profile of children and adolescents. A search in the PubMed, Scopus, Cochrane and LILACS databases was carried out to locate cross-sectional and longitudinal studies, with or without intervention, in apparently healthy children and/or adolescents, who had the intake of ultra-processed food as an exposure variable and the lipid profile as an outcome. After screening, 14 studies were included, of which nine demonstrated that ultra-processed food consumption was related to increased LDL-c, total cholesterol, triglycerides and a reduction in HDL-c. Three studies found no relationship and two demonstrated that the increased intake of ready-to-eat cereals was related to the decrease in total cholesterol and LDL-c. There was a high consumption of ultra-processed foods and positive relation with blood lipids among children and adolescents, which calls attention to interventions, such as nutritional education, with a view to reducing the intake of these foods.

[Association between ultra-processed food consumption and lipid parameters among adolescents].

Cien Saude Colet 2020 Oct 13;25(10):4055-4064. Epub 2019 Feb 13.

Departamento de Nutrição, UFPI. Teresina PI Brasil.

The scope of this study was to analyze the association between ultra-processed food (UPF) consumption and lipid parameters. It was a cross-sectional study performed with high school adolescents. Food consumption was analyzed by means of a 24-hour food recall form, where UPF were identified in line with the NOVA system of food classification. The total cholesterol levels, HDL-c and triglycerides were determined by enzymatic colorimetry and the LDL-c fraction estimated by formula. The Student's t-test or Mann-Whitney was used to compare averages, and linear regression to make associations among the variables. The results show that UPF consumption was more frequent in female adolescents between 17 and 19 years of age, with a family income above two minimum wages and from private schools. It was observed that individuals in the upper third of UPF consumption had a higher energetic, carbohydrate and sodium intake, with a lower intake of proteins and fibers. Moreover, it was found that a higher UPF intake was negatively associated with HDL-c levels and positively associated with triglyceride levels and dyslipidemia. Therefore, UPF is associated with a worsening of the nutritional profile of the diet and contributes to negative changes in the lipid parameters of young individuals.

Lycopene-Rich Extract from Red Guava ( L.) Decreases Plasma Triglycerides and Improves Oxidative Stress Biomarkers on Experimentally-Induced Dyslipidemia in Hamsters.

Nutrients 2019 Feb 13;11(2). Epub 2019 Feb 13.

Medicinal Plants Research Center, Federal University of Piaui, Teresina, PI 64.049-550, Brazil.

This work assessed the effects of a 28-day treatment with lycopene-rich extract (LRE) from red guava fruit ( L.) on the lipid profile and oxidative stress in an experimental model of dyslipidemia. Male hamsters (116.5 ± 2.16 g) were fed with the AIN 93G diet containing casein (20%), coconut fat (13.5%) and cholesterol (0.1%). The animals were divided into four groups: normolipidemic control (standard feed; NC, = 7); hypercholesterolemic control (HC, = 7); LRE 25 mg/kg/day (LRE-25, 7) and LRE 50 mg/kg/day (LRE-50, 9). After treatment, plasma concentrations of triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL) cholesterol (LDL-c), high-density lipoprotein (HDL) cholesterol (HDL-c), malondialdehyde (MDA-p) and myeloperoxidase (MPO), as well as erythrocytic superoxide dismutase (SOD-e) and the atherogenic index, were determined. Malondialdehyde (MDA-h), catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD-h) levels were assessed. Feed intake (FI) and weight gain (WG) were also determined. The LRE-25 group presented significantly lower TG levels and atherogenic index than did the HC group ( < 0.05). Both LRE-25 and LRE-50 groups presented lower levels of MDA-p and MPO than did the HC group ( < 0.05). LRE demonstrated a promising effect against dyslipidemia and oxidative stress.

Nectar Supplementation Reduced Biomarkers of Oxidative Stress, Muscle Damage, and Improved Psychological Response in Highly Trained Young Handball Players.

Front Physiol 2018 31;9:1508. Epub 2018 Oct 31.

Group of Studies on Exercise Physiology Applied to Performance and Health, Department of Biophysics and Physiology, Federal University of Piauí, Teresina, Brazil.

The purpose of this study was to investigate the effects of (SC) nectar supplementation on performance, markers of oxidative stress, muscle damage, and psychological response in Handball players. Twenty-five young athletes (age = 18.6 ± 2.4 years) from an elite high school national level Brazilian Handball team were randomized into two study groups: SC/Jamelon nectar (SC, = 12) and placebo ( = 13). The subjects ingested 10 mL/kg/day of Jamelon nectar or placebo 30 min before the training sessions and immediately after training cessation, for 28 days. Body mass index (BMI) and percentage of fat mass were assessed using bioelectrical impedance analysis. Biomarkers of oxidative stress were measured by lipid peroxidation, which was quantified by malondialdehyde (MDA). Total antioxidant capacity (TAC), creatine kinase (CK) activity, and lactate dehydrogenase (LDH) were determined. The 20 m shuttle run test, vertical jump, and running anaerobic sprint test were assessed to verify performance and the fatigue index was calculated. The Profile of Mood States (POMS) questionnaire was used for psychological evaluation. Both groups demonstrated improved vertical jump performance and a decreased fatigue index over time but without significant differences between them regarding performance. There was statistically significance only for SC in CK, LDH, and MDA, and TAC was greater in the SC compared to placebo. Furthermore, only the SC group demonstrated improved mood disturbance and confusion after the intervention. In conclusion, the present study suggests that SC nectar supplementation reduced biomarkers of oxidative stress and muscle damage, and improved psychological response in young handball players.

Cholesterol-Lowering and Liver-Protective Effects of Cooked and Germinated Mung Beans ( L.).

Nutrients 2018 Jun 26;10(7). Epub 2018 Jun 26.

Department of Nutrition, Universidade Federal do Piauí, Campus Universitário Ministro Petrônio Portela, Teresina, PI 64.049-550, Brasil.

We investigated the hypocholesterolemic and liver-protective effects of cooked and germinated whole mung beans. Hamsters were fed for 28 days on diets rich in saturated fatty acids and cholesterol, differing only in protein source (20%): casein, cooked whole mung bean, and germinated mung bean. After 28 days, we found reduced plasma concentrations of total cholesterol and non-HDL cholesterol, increased faecal cholesterol excretion, and reduced levels of asparagine aminotransferase and alanine aminotransferase enzymes in the liver. Reduction in hepatic lipid deposition was observed between each of the mung bean groups relative to the casein group. In addition, the animals of the geminated mung bean group showed a lack of inflammatory infiltrate and better vascularisation of the hepatic tissue. Results from this study show significant hypocholesterolemic and liver-protective properties of the mung bean, which are further enhanced after germination.

Prevalence of photoprotection and its associated factors in risk group for skin cancer in Teresina, Piauí.

An Bras Dermatol 2017 Mar-Apr;92(2):206-210

Faculdade Facid-DeVry - Teresina (PI), Brazil.

Background:: The incidence of skin cancer has increased worldwide, particularly melanoma rates, which had a mean development of 2.6 % a year in the last 10 years. The agreement on the relation between long-term or chronic exposure to the sun and the emergence of these neoplasias has made several workers who perform activities exposed to solar radiation to form a risk group for the development of skin cancer, community health agents included.

Objectives:: To analyze the prevalence of sunscreen-use-related factors to skin cancer in a labor risk group.

Methodology:: Cross-sectional study with community health agents selected through simple random sampling. After collecting data using semi-structured interviews, a descriptive analysis was performed for the qualitative variables, bivariate analysis was employed for checking the association between sunscreen use and sociodemographic, occupational and knowledge about skin variables, and multivariate analysis was conducted to check independent variables associated to sunscreen use. A 5% significance level was used.

Results:: Of 261 health gents selected, 243 were able to participate in the study. The prevalence rate of sunscreen use was 34.2% (95% CI: 28.2-40.2). Factors associated with sunscreen use were female sex, advanced age, use of sunscreen in situations when the skin got burnt, knowledge of the negative effects of the sun on the skin and skin cancer history.

Conclusions:: The prevalence found reveals that there is a need for implementing educational strategies in health services regarding photoprotection.

Effect of magnesium supplementation on insulin resistance in humans: A systematic review.

Nutrition 2017 Jun 2;38:54-60. Epub 2017 Feb 2.

Department of Nutrition, Federal University of Piaui, Campus Minister Petrônio Portela, Ininga, Teresina, Piaui, Brazil. Electronic address:

Objectives: Recent studies have demonstrated that minerals play a role in glucose metabolism disorders in humans. Magnesium, in particular, is an extensively studied mineral that has been shown to function in the management of hyperglycemia, hyperinsulinemia, and insulin resistance (IR) action. The aim of this study was to investigate the effect of magnesium supplementation on IR in humans via systematic review of the available clinical trials.

Methods: This review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. A survey was conducted to select clinical trials related to the effects of this mineral in insulin sensitivity using the following databases: PubMed, SciVerse Scopus, ScienceDirect, and SciVerse Cochrane.

Results: After the selection process, 12 articles were identified as eligible, representing different clinical conditions and being free of restriction with regard to sex, age, ethnicity, and differential dosing/shape of magnesium. The results of eight clinical trials showed that supplementation with magnesium influences serum fasting glucose concentrations, and five trials determined an effect on fasting insulin levels. The results of seven studies demonstrated that mineral supplementation reduced homeostasis model assessment for IR values.

Conclusions: The data of this systematic review provide evidence as to the benefits of magnesium supplementation in reducing IR in patients with hypomagnesemia presenting IR. However, new intervention studies are needed to elucidate the role of the nutrient in protection against this metabolic disorder, as well as the standardization of the type, dose, and time of magnesium supplementation.

IN VITRO AND IN VIVO ANTIOXIDANT ACTIVITY OF BURITI FRUIT (MAURITIA FLEXUOSA L.F.).

Nutr Hosp 2015 Nov 1;32(5):2153-61. Epub 2015 Nov 1.

Federal University of Piauí. Teresina-Piaui..

Introduction: studies have shown high concentration of monounsaturated fatty acids, carotenoids, polyphenols and ascorbic acid in Buriti fruit (Mauritia flexuosa L.f.). This study evaluated the in vitro and in vivo antioxidant activities of buriti fruit (Mauritia flexuosa L.f.).

Methods: the chemical composition and total phenolic and carotenoid contents of the buriti pulp and the feed rations were determined, and the in vitro antioxidant activity was analyzed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical assay. Wistar rats (21 days old) were randomly allocated (n=10) into a control groups and experimental groups (feed enriched with buriti pulp). After 60 days, the in vivo antioxidant activity was evaluated through the determination of the catalase activity and non-protein sulfhydryl (NPSH) groups in the liver and quantification of malondialdehyde (MDA) in the plasma and tissues.

Results: high contents of oleic fatty acids (73.3%), phenolic compounds (192 ± 0.3 mg/100 g) and carotenoids (23.9 ± 0.5 mg/100 g) as well as elevated in vitro antioxidant activity were found in the buriti pulp. The enriched diet had higher contents of phenols and carotenoids as well as higher antioxidant activity compared with the standard feed (p < 0.05). There were no differences between the groups regarding catalase activity in the liver and MDA concentrations in the plasma, liver and kidneys. The male rats of the experimental group had higher liver concentrations of NPSH compounds (p < 0.05).

Conclusion: these results may corroborate the claim that buriti fruit is an antioxidant functional food and support its utilization in a nutritionally balanced diet.

Ferulic acid ethyl ester diminished Complete Freund's Adjuvant-induced incapacitation through antioxidant and anti-inflammatory activity.

Naunyn Schmiedebergs Arch Pharmacol 2016 Jan 24;389(1):117-30. Epub 2015 Oct 24.

Ferulic acid ethyl ester (FAEE) is a derivate from ferulic acid which reportedly has antioxidant effect; however, its role on inflammation was unknown. In this study, we investigated the orally administered FAEE anti-inflammatory activity on experimental inflammation models and Complete Freund's Adjuvant (CFA)-induced arthritis in rats. CFA-induced arthritis has been evaluated by incapacitation model and radiographic knee joint records at different observation time. FAEE (po) reduced carrageenan-induced paw edema (p < 0.001) within the 1st to 5th hours at 50 and 100 mg/kg doses. FAEE 50 and 100 mg/kg, po inhibited leukocyte migration into air pouch model (p < 0.001), and myeloperoxidase, superoxide dismutase, and catalase activities (p < 0.001) increased total thiol concentration and decreased the TNF-α and IL-1β concentrations, NO, and thiobarbituric acid reactive species. In the CFA-induced arthritis, FAEE 50 and 100 mg/kg significantly reduced the edema and the elevation paw time, a joint disability parameter, since second hour after arthritis induction (p < 0.001). FAEE presented rat joint protective activity in radiographic records (p < 0.001). The data suggest that the FAEE exerts anti-inflammatory activity by inhibiting leukocyte migration, oxidative stress reduction, and pro-inflammatory cytokines.

Hypoalbuminemia and oxidative stress in patients on renal hemodialysis program.

Nutr Hosp 2014 Oct 1;30(4):952-9. Epub 2014 Oct 1.

Graduate student in Medicine. Federal University of Piaui. Teresina-Piaui, Brazil..

Introduction: Albumin is considered an important extracellular antioxidant molecule. hypoalbuminemia is a strong and independent predictor of mortality in patients on hemodialysis. The present study evaluated the relation between hypoalbuminemia and oxidative stress by comparing superoxide dismutase activity, lipid peroxidation and antioxidant micronutrient consumption in chronic renal failure patients.

Methods: A case-control study was carried out with 64 patients of both sexes aged 18 to 59 years. The patients with hypoalbuminemia (ALB < 3,5 g/dL) were defined as case (n = 26) and control (n = 38) those with ALB ≥ 3.5 g/dL.Determinations of activity superoxide dismutase (SOD)and nitric oxide production by the contraction of nitrite in erythrocytes, concentration of malondialdehyde (MDA)in plasma, lipid profile and micronutrient antioxidants intake were performed. For comparisons between groups,the Student t test was used. Possible associations between variables were tested using the chi-square test and Pearson correlation test.

Results: Consumption of copper was significantly lower(p < 0.05) in the group with hypoalbuminemia. There was a positive correlation between the concentrations of albumin and intake copper (r = 0.280). Negative correlation was found between albumin and MDA concentrations.

Conclusion: Hypoalbuminemia is associated with increased lipid peroxidation, and can contribute to oxidative stress in chronic renal failure patients. Additionally, patients with chronic renal disease undergoing hemodialysis evaluated in this study had reduced consumption of cooper.

Use of anti-obesity drugs among college students.

Rev Assoc Med Bras (1992) 2011 Sep-Oct;57(5):570-6

Universidade Federal do Piauí, PI, Brazil.

Objective: To evaluate the use of anti-obesity drugs among students attending a public university.

Methods: This was a cross sectional random study of 664 college students. Drug use, socioeconomic, and anthropometric variables were observed. Body mass index (BMI) and waist circumference (WC) were classified according to World Health Organization criteria.

Results: Current or previous use of anti-obesity drugs was reported by 6.8% of students. Amphetamine and sympathomimetic amines (40.5%) were the most commonly used drugs. Among those who reported use of anti-obesity agents, 62.2% were female. Only 31.1% of medications were prescribed by doctors. Mean BMI and WC were higher among students reporting the use of such drugs, but 47% of them were classified as eutrophic by BMI, and 76.5% had normal WC measure.

Conclusion: The use of anti-obesity drugs among college students is of concern, particularly due to the high proportion of drug use without indication or prescription.

Rev Assoc Med Bras (1992) 2011 Jan-Feb;57(1):50-5

Universidade Federal do Piauí, Teresina, PI.

Objective: To determine prevalence of overweight and abdominal fat in adult population in the urban area of Teresina-PI.

Methods: Cross-sectional study with probabilistic sample by conglomerates. The study evaluated 464 adults, 20 to 59 years of age living in the urban area of Teresina-PI. Nutritional status was classified by the body mass index (BMI) and abdominal fat accumulation was estimated according to waist circumference. The significance level was set at 5% (p<0.05).

Results: Prevalence of overweight and obesity according to nutritional status based on BMI was, respectively, 30.0% and 7.7%. There was an increase in the proportion of overweight and obesity among men with progressively higher family income. Highest rates of obesity were found among individuals 50 to 59 years of age with stable marriages and nonsmokers. No association was found between individual or family income and presence of abdominal fat in the population.

Conclusion: Prevalence of overweight in the study population follows the Brazilian trend. Proportions of overweight and obesity were higher among men and increased with age. Women and married persons showed a greater tendency for abdominal obesity.

Arq Bras Cardiol 2010 Aug 18;95(2):192-9. Epub 2010 Jun 18.

Universidade Federal do Piauí, Teresina, PI, Brazil.

Background: High blood pressure, excess weight and sedentary lifestyle are important risk factors for cardiovascular diseases, and they are closely associated.

Objective: To evaluate the nutritional status, level of physical activity and blood pressure levels of students of Universidade Federal do Piauí, Teresina, Brazil.

Methods: Cross-sectional study with a sample of 605 students (46.1% males and 53.9% females), with a mean age of 21.7 ± 3.7 years. The nutritional status was classified according to body mass index (BMI), and central adiposity according to waist circumference (WC). The level of physical activity was evaluated using the short version of the International Physical Activity Questionnaire (IPAQ). Elevated blood pressure was defined as systolic blood pressure > 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg.

Results: The prevalence of elevated blood pressure was 9.7%, and was higher among men. Excess weight (BMI > 25 kg/m(2)) was found in 18.2% of the students, with overweight and obesity rates of 15.2% and 3%, respectively. Abdominal obesity was found in 2.4% of the students regardless of gender, and sedentary lifestyle in 52%. The mean blood pressure increased with increasing BMI and WC. No association was found between the levels of physical activity and blood pressure.

Conclusion: An association of increased body weight and waist circumference with higher blood pressure levels was observed among the participants. Instruments for an early assessment of the cardiovascular risk and preventive advice should be established for these young individuals.

[The social representations of hospital-acquired infections elaborated by nursing professionals].

Rev Bras Enferm 2008 Jul-Aug;61(4):441-6

Faculdade NOVAFAPI, Teresina, PI.

Prevention and control of hospital acquired infections is a constant challenge for the nursing professionals. This study sought to grasp the social representations of hospital-acquired infections elaborated from the perceptions of nursing professionals, and to discuss how these representations influence their practices in controlling and preventing infections. This is a qualitative research, applied in a reference urgency-emergence service, which used as a data collection technique the semi-structured interview, and for content analysis the category elaboration. It was observed that the execution of the activities is closely tied to the individual subjectivities of each professional and deeply dependant on the moral, ethical, ideological and subjective values of these professionals, regarding interpretation, judging and personal decision in the application of the scientific knowledge.
