RESUMO

BACKGROUND: Although germline BRCA mutations have been associated with adverse outcomes in prostate cancer (PC), understanding of the association between somatic/germline alterations in homologous recombination repair (HRR) genes and treatment outcomes in metastatic castration-resistant PC (mCRPC) is limited. The aim of this study was to investigate the prevalence and outcomes associated with somatic/germline HRR alterations, particularly BRCA1/2, in patients initiating first-line (1L) mCRPC treatment with androgen receptor signalling inhibitors (ARSi) or taxanes. PATIENTS AND METHODS: Data from 729 mCRPC patients were pooled for CAPTURE from four multicentre observational studies. Eligibility required 1L treatment with ARSi or taxanes, adequate tumour samples and biomarker panel results. Patients underwent paired normal and tumour DNA analyses by next-generation sequencing using a custom gene panel including ATM, BRCA1, BRCA2, BRIP1, CDK12, CHEK2, FANCA, HDAC2, PALB2, RAD51B and RAD54L. Patients were divided into subgroups based on somatic/germline alteration(s): with BRCA1/2 mutations (BRCA); with HRR mutations except BRCA1/2 (HRR non-BRCA); and without HRR alterations (non-HRR). Patients without BRCA1/2 mutations were classified as non-BRCA. Radiographic progression-free survival (rPFS), progression-free survival 2 (PFS2) and overall survival (OS) were assessed. RESULTS: Of 729 patients, 96 (13.2%), 127 (17.4%) and 506 (69.4%) were in the BRCA, HRR non-BRCA and non-HRR subgroups, respectively. BRCA patients performed significantly worse for all outcomes than non-HRR or non-BRCA patients (P < 0.05), while PFS2 and OS were significantly shorter for BRCA than HRR non-BRCA patients (P < 0.05). HRR non-BRCA patients also had significantly worse rPFS, PFS2 and OS than non-HRR patients. Exploratory analyses suggested that for BRCA patients, there were no significant differences in outcomes associated with 1L treatment choice (ARSi or taxanes) or with the somatic/germline origin of the alterations. CONCLUSIONS: Worse outcomes were observed for mCRPC patients in the BRCA subgroup compared with non-BRCA subgroups, either HRR non-BRCA or non-HRR. Despite its heterogeneity, the HRR non-BRCA subgroup presented worse outcomes than the non-HRR subgroup. Screening early for HRR mutations, especially BRCA1/2, is crucial in improving mCRPC patient prognosis.

RESUMO

Congenital Zika Syndrome (CZS) is characterized by many impairments especially in the central nervous system, potentially compromising neurodevelopment and causing significant morbidity in affected children. The aim was to assess gross motor function in children with CZS. This was a cross-sectional investigation nested within a prospective cohort study of children with CZS based in a Brazilian referral hospital in Rio de Janeiro. Between March/2017 and February/2018, we performed gross motor function assessments using the Gross Motor Function Classification (GMFCS) and the Gross Motor Function Measure (GMFM), estimating the mean and standard deviation of GMFM scores among GMFCS groups. The study sample included 72 children, with a median age of 13 months (7-25). Of these, 63 (87.5%) had severe motor impairment, 3 (4%) had moderate impairment, and 6 (8%) had mild impairment. The mean GMFM score for each group was respectively 11.6, 26.1, and 81.6, with statistically significant differences (p-value < 0.001). Severely affected children only achieved head control in the sitting posture when supported. Children with milder forms were able to develop walking skills.Conclusion: Most children with CZS have major motor disabilities and a poor prognosis. Better understanding of limitations and functionality in children with CZS can serve as a prognostic guide in their management. What is Known: • Severe motor impairment was present in 63 (87.5%) children with CZS. • The degree of neurological impairment was inversely associated with motor performance. What is New: • Microcephaly was more frequent among children with severe gross motor function impairment. • Children with CZS have major motor disabilities and a poor prognosis.

RESUMO

Good fundamentals of posture and balance are essential for the efficient performance of both simple daily tasks and more complex movement patterns. In particular, postural balance is the ability to keep the body in equilibrium and to regain balance after the shift of body segments: postural control mechanisms of integration of the visual, vestibular and foot afferential channels contribute to this. This document provides recommendations based on scientific evidence, clinical practice, and consensus between experts concerning the prevention, diagnosis, and treatment of postural dysfunction at the three stages of life as the developmental age, adult age, and old age > 65 years and follows the "National Guidelines on Classification and Measuring of Posture and its Dysfunctions" per the Italian Ministry of Health (December 2017). The paper answers four main questions: i) "Which measures can be adopted to prevent postural dysfunctions?" ii) "What can we do in order to make a correct diagnosis of postural dysfunction?" iii) "What are the correct treatment programs for postural dysfunctions?" iv) Which professional competencies and experiences are useful for preventing, diagnosing and treating postural dysfunctions? By the Consensus of the Experts and the scientific evidence, emerge that the approach to postural dysfunctions requires a multidisciplinary and interdisciplinary team. Furthermore, rehabilitation treatment interventions must be specific to the age groups that have been indicated, to consider the integration of the main systems and subsystems of postural control that change with age.

RESUMO

Pesticides are key stressors of soil microorganisms with reciprocal effects on ecosystem functioning. These effects have been mainly attributed to the parent compounds, while the impact of their transformation products (TPs) has been largely overlooked. We assessed in a meadow soil (soil A) the transformation of iprodione and its toxicity in relation to (i) the abundance of functional microbial groups, (ii) the activity of key microbial enzymes, and (iii) the diversity of bacteria, fungi, and ammonia-oxidizing microorganisms (AOM) using amplicon sequencing. 3,5-Dichloroaniline (3,5-DCA), the main iprodione TP, was identified as a key explanatory factor for the persistent reduction in enzymatic activities and potential nitrification (PN) and for the observed structural changes in the bacterial and fungal communities. The abundances of certain bacterial (Actinobacteria, Hyphomicrobiaceae, Ilumatobacter, and Solirubrobacter) and fungal (Pichiaceae) groups were negatively correlated with 3,5-DCA. A subsequent study in a fallow agricultural soil (soil B) showed limited formation of 3,5-DCA, which concurred with the lack of effects on nitrification. Direct 3,5-DCA application in soil B induced a dose-dependent reduction of PN and NO3--N, which recovered with time. In vitro assays with terrestrial AOM verified the greater toxicity of 3,5-DCA over iprodione. "Candidatus Nitrosotalea sinensis" Nd2 was the most sensitive AOM to both compounds. Our findings build on previous evidence on the sensitivity of AOM to pesticides, reinforcing their potential utilization as indicators of the soil microbial toxicity of pesticides in pesticide environmental risk analysis and stressing the need to consider the contribution of TPs in the toxicity of pesticides on the soil microbial community.IMPORTANCE Pesticide toxicity on soil microorganisms is an emerging issue in pesticide risk assessment, dictated by the pivotal role of soil microorganisms in ecosystem services. However, the focus has traditionally been on parent compounds, while transformation products (TPs) are largely overlooked. We tested the hypothesis that TPs can be major contributors to the soil microbial toxicity of pesticides using iprodione and its main TP, 3,5-dichloroaniline, as model compounds. We demonstrated, by measuring functional and structural endpoints, that 3,5-dichloroaniline and not iprodione was associated with adverse effects on soil microorganisms, with nitrification being mostly affected. Pioneering in vitro assays with relevant ammonia-oxidizing bacteria and archaea verified the greater toxicity of 3,5-dichloroaniline. Our findings are expected to advance environmental risk assessment, highlighting the potential of ammonia-oxidizing microorganisms as indicators of the soil microbial toxicity of pesticides and stressing the need to consider the contribution of TPs to pesticide soil microbial toxicity.

RESUMO

The objective of this study was to evaluate the effect of feeding laying hens diets containing cashew nut shell liquid (CNSL) as a source of anacardic acid on the blood biochemical parameters as well as the enzymatic activity and lipid peroxidation of liver and tissues of the reproductive system (ovary, magnum, and uterus). A total of 216 Hisex White commercial laying hens were distributed randomly into six treatments, with six replicates of six birds. Treatments consisted of a diet without growth promoter (GP); a diet with GP; and diets without GP, with addition of increasing levels of CNSL (0.25, 0.50, 0.75 and 1.0%). Addition of CNSL to the diet did not affect the blood biochemical parameters (uric acid, creatinine, alanine aminotransferase, aspartate aminotransferase, total cholesterol, high density lipoproteins, low-density lipoproteins and triglycerides), the enzymatic activity (superoxide dismutase and nonprotein sulphydryl groups) in the organs (liver, ovary, magnum and uterus) or the peroxidation of lipids from the blood serum, liver, magnum and uterus (p > 0.05). However, the addition of 0.75% and 1.00% CNSL provided a lower thiobarbituric acid reactive substances content in the birds' ovary (p < 0.001) compared to birds of other treatments, whereas the treatment without the GP provided a higher value. Addition of up to 1% of the CNSL as a source of anacardic acid in the laying hens' diets does not influence blood biochemical parameters or the endogenous enzymatic activity in the liver, ovary, magnum and uterus, but affects the lipid peroxidation in the ovary, although the problem is reduced from the inclusion of 0.75% CNSL.

RESUMO

A large evidence-based review on the effects of a moderate consumption of beer on human health has been conducted by an international panel of experts who reached a full consensus on the present document. Low-moderate (up to 1 drink per day in women, up to 2 in men), non-bingeing beer consumption, reduces the risk of cardiovascular disease. This effect is similar to that of wine, at comparable alcohol amounts. Epidemiological studies suggest that moderate consumption of either beer or wine may confer greater cardiovascular protection than spirits. Although specific data on beer are not conclusive, observational studies seem to indicate that low-moderate alcohol consumption is associated with a reduced risk of developing neurodegenerative disease. There is no evidence that beer drinking is different from other types of alcoholic beverages in respect to risk for some cancers. Evidence consistently suggests a J-shaped relationship between alcohol consumption (including beer) and all-cause mortality, with lower risk for moderate alcohol consumers than for abstainers or heavy drinkers. Unless they are at high risk for alcohol-related cancers or alcohol dependency, there is no reason to discourage healthy adults who are already regular light-moderate beer consumers from continuing. Consumption of beer, at any dosage, is not recommended for children, adolescents, pregnant women, individuals at risk to develop alcoholism, those with cardiomyopathy, cardiac arrhythmias, depression, liver and pancreatic diseases, or anyone engaged in actions that require concentration, skill or coordination. In conclusion, although heavy and excessive beer consumption exerts deleterious effects on the human body, with increased disease risks on many organs and is associated to significant social problems such as addiction, accidents, violence and crime, data reported in this document show evidence for no harm of moderate beer consumption for major chronic conditions and some benefit against cardiovascular disease.

RESUMO

BACKGROUND AND AIM: Prehypertension is an increasingly highly prevalent condition in the general population, and is associated with an increased risk for coronary heart disease and stroke. However, evidence from population-based studies of the risk factors for prehypertension is scant. We sought to examine the predictors of progression from normotension to prehypertension in a community-based population from Western New York. METHODS AND RESULTS: A longitudinal analysis, over 6 years of follow-up, among 569 men and women (mean age 51.8 years) who were free of prehypertension, hypertension, cardiovascular disease and diabetes at the baseline examination, in the Western New York Health Study (WNYHS). Incident prehypertension at follow-up was defined as systolic blood pressure of 120-139 mm Hg and/or diastolic blood pressure of 80-89 mm Hg. The cumulative six year incidence of prehypertension was 33.5% (189/564). In bivariate analyses, there were several correlates of incident prehypertension, including age, BMI and waist circumference, impaired fasting glucose (IFG), uric acid, and baseline blood pressure levels. After multivariate adjustment, IFG at baseline [odds ratio (OR): 1.70, 95% CI: 1.07-2.69) and weight gain since age 25 (OR: 1.12, 1.04-1.21 per 10 lb increase)] were the strongest significant predictors of prehypertension at follow-up. Neither baseline waist circumference nor change in BMI were predictor variables in models when they were substituted for weight gain. CONCLUSIONS: Results from this study suggest early dysregulation of glucose metabolism and weight gain over the lifespan may represent important risk factors for prehypertension in the general population.

RESUMO

Mounting evidence supports the hypothesis that functional foods containing physiologically-active components may be healthful. Longitudinal cohort studies have shown that some food classes and dietary patterns are beneficial in primary prevention, and this has led to the identification of putative functional foods. This field, however, is at its very beginning, and additional research is necessary to substantiate the potential health benefit of foods for which the diet-health relationships are not yet scientifically validated. It appears essential, however, that before health claims are made for particular foods, in vivo randomized, double-blind, placebo controlled trials of clinical end-points are necessary to establish clinical efficacy. Since there is need for research work aimed at devising personalized diet based on genetic make-up, it seems more than reasonable the latter be modeled, at present, on the Mediterranean diet, given the large body of evidence of its healthful effects. The Mediterranean diet is a nutritional model whose origins go back to the traditional dietadopted in European countries bordering the Mediterranean sea, namely central and southern Italy, Greece and Spain; these populations have a lower incidence of cardiovascular diseases than the North American ones, whose diet is characterized by high intake of animal fat. The meeting in Naples and this document both aim to focus on the changes in time in these two different models of dietary habits and their fall out on public health.

RESUMO

OBJECTIVE: To investigate depression, anxiety and cognitive impairment and their associations with clinical and socio-demographic variables in type 2 diabetes. METHODS: The Zung Self-Rating Depression-Anxiety Scale and Mini-Mental State Examination (MMSE) were administered at baseline and after 4 years to 498 consecutive patients, 249 non-insulin treated (NIT) and 249 insulin treated (IT), aged 40-80 years. RESULTS: At baseline, IT patients were older, had longer disease duration, higher HbA1c and did more glucose monitoring (p < 0.001, all) but their depression scores were lower than among NIT (p = 0.006), with no differences for anxiety or MMSE. After 4 years, 72 patients were lost to the follow-up, of whom 18 had died. 41 NIT had switched to insulin and increased BMI (p = 0.004), blood pressure (p < 0.001), retinopathy severity (p = 0.03) and microalbuminuria (p = 0.0045), but did not change their scores for depression, anxiety or MMSE. The remaining 171 NIT improved fasting glucose (p = 0.006), total cholesterol (p < 0.0001), triglyceride (p = 0.0026) and HbA1c (p = 0.0006). Despite increased prevalence of microalbuminuria and retinopathy (p < 0.0001, both), depression (p = 0.04) and MMSE (p = 0.0007) improved. Foot ulcers (p = 0.03), retinopathy (p < 0001), microalbuminuria (p = 0.0047) and hypertension (p < 0.0001) increased in the remaining 214 IT patients, in whom depression (p = 0.0005) and anxiety (p < 0.0001) worsened while MMSE improved slightly (p = 0.0002). On multivariate analysis, depression was associated with being a woman and anxiety with diabetes duration and lower schooling, which also affected MMSE scores. CONCLUSIONS: Depression was associated with female gender and worsening complications but not modified by diabetes duration or switching to insulin therapy. Diabetes duration and lower schooling may affect anxiety and cognitive impairment.

RESUMO

Herbicides play a pivotal role in paddy rice cultivation by effectively controlling weeds, thus ensuring optimal resource utilisation and higher crop yields, making them indispensable for efficient rice production systems. However, herbicide applications could be related to potential environmental impacts such as water contamination and harm to non-target species, requiring special attention in their management to ensure the long-term sustainability of rice farming practices. The development and utilisation of robust risk assessment indicators for pesticides are essential tools in evaluating and mitigating potential environmental and human health hazards associated with pesticide use in agricultural practices. The Environmental Potential Risk Indicator for Pesticides (EPRIP) is not suitable for rice paddy cultivation due to its limitations in accurately assessing pesticide risk in this specific agricultural context. This is primarily attributed to the unique hydrological characteristics and ecosystem dynamics of paddy fields, which significantly differ from other agricultural systems. To address this issue and to enhance the accuracy of pesticide risk assessment in rice paddy fields, EPRIP has been improved and validated in two agricultural seasons. A synergistic approach involving field experiments and enhanced EPRIP model simulations was employed to assess the risk associated with the application of two herbicides in Italian paddy rice systems. The observed and model-predicted surface water (SW) concentrations exhibited a close alignment, though an overestimation was observed for groundwater (GW). In general, the estimated Risk Points (1 for SW and 4 for GW) were largely in accord with those derived from the field experiments (1 for SW and 3 for GW), suggesting that the refined EPRIP model holds promise for conducting reliable risk assessments following herbicide applications in such contexts.

RESUMO

Variability in snake venom composition is well-documented and crucial for understanding snake ecology and predicting snakebites. In this study, we characterize the venom composition and biological activities of newborn female and male Bothrops moojeni and their mother. Our results reveal significant differences between the venom of newborn females and males, demonstrating a broad and diverse range of proteins. The venoms of newborn females showed higher serine protease effects, increased hemorrhagic activity, and greater lethality compared to the venom of newborn males. However, no differences were observed in phospholipase A2 and coagulant activity. The differences in protein composition and toxic activities between maternal and neonatal venom, as well as between the venoms of newborn females and males, contribute to understanding the diverse outcomes of snakebites. These results underscore the importance of considering sex and ontogeny in understanding venom composition in snakes.

RESUMO

The present study focused on investigating the antioxidant, antiglycation activity, digestive enzymes inhibition, bioaccessibility and hypoglycemic effect of C. arabica leaves extracts. The extracts deactivated the O2•-, ROO•, H2O2, HOCl reactive oxygen species. Coffee leaves showed strong inhibition of α-glucosidase (IC50 = 40.30 µg mL-1) greater than the isolated metabolites and acarbose. There was also inhibition of pancreatic lipase (IC50 = 56.43 µg mL-1) in addition to a hypoglycemic effect in zebrafish similar to acarbose and metformin. With the exception of rutin, all biocompounds were detected at all stages of in vitro digestion. Finally, these results suggest that C. arabica leaf extracts possess antidiabetic and anti-obesity properties that can be attributed to the main metabolites and the synergistic action between them.Communicated by Ramaswamy H.

RESUMO

Education in reproductive science is operating from an outdated paradigm of teaching and learning. Traditionally, reproductive education follows the pattern where students read a textbook, listen to instructor presentations, re-read the textbook and class notes and then complete a test. This paradigm is inefficient, costly and has not incorporated the potential that technology can offer with respect to increases in student learning. Further, teachers of reproductive science (and all of science for that matter) have little training in the use of documented methods of instructional design and cognitive psychology. Thus, most of us have learned to teach by repeating the approaches our mentors used (both good and bad). The technology now exists to explain complex topics using multimedia presentations in which digital animation and three-dimensional anatomical reconstructions greatly reduce time required for delivery while at the same time improving student understanding. With funding from the Small Business Innovation Research program through the U.S. Department of Education, we have developed and tested a multimedia approach to teaching complex concepts in reproductive physiology. The results of five separate experiments involving 1058 university students and 122 patients in an OB/GYN clinic indicate that students and patients learned as much or more in less time when viewing the multimedia presentations when compared to traditional teaching methodologies.

RESUMO

The serpent study involves physiological, behavioral and interaction factors with an extremely dynamic and complex environment. The relation of these animals with biodiversity is still quite preliminary, little studied and sustained by popular practices related to traditional medicine, esoteric and mystical currents. Therefore, this study proposed to know about the effect of 80% crude alcoholic extract of Petiveria alliacea L., popularly known as Tipi Herb, and its effects associated with the repellency of the Bothrops moojeni serpent. A complex of boxes was built for the observation of the snake's displacement, carried out for a total period of six days, the first three for defining the exploratory pattern and the other two for testing the alcoholic extract of Tipi, and finally on the sixth day, one cycle with the presence of a live attractant as bait. It was observed that the animal had no inhibition behavior and moved through the complex in a way like what occurs in nature and showed behavior to avoid remaining in the presence of the extract both with the presence of a live attractant or without it, preferring to move in the other compartments. The results show that this proposed tool is valid for the study of displacement of Bothrops moojeni snakes, in the same way that it added values on the importance of cerrado biome biodiversity and on the popular medicine practices of Tipi Herb, since the repellent effect on the snake was significant in the two tests performed.

RESUMO

Knowledge of how congenital Zika syndrome (CZS) impacts motor development of children longitudinally is important to guide management. The objective of the present study was to describe the evolution of gross motor function in children with CZS in a Rio de Janeiro hospital. In children with CZS without arthrogryposis or other congenital osteoarticular malformations who were followed in a prospective cohort study, motor performance was evaluated at two timepoints using the Gross Motor Function Classification System (GMFCS) and the Gross Motor Function Measurement test (GMFM-88). Among 74 children, at the baseline evaluation, the median age was 13 (8-24) months, and on follow-up, 28 (24-48) months. According to GMFCS at the second timepoint, 6 children were classified as mild, 11 as moderate, and 57 as severe. In the GMFM-88 assessment, children in the severe group had a median score of 10.05 in the baseline evaluation and a follow-up score of 12.40, the moderate group had median scores of 25.60 and 29.60, and the mild group had median scores of 82.60 and 91.00, respectively. Although a small developmental improvement was observed, the motor impairment of children was mainly consistent with severe cerebral palsy. Baseline motor function assessments were predictive of prognosis.

RESUMO

BACKGROUND AND AIMS: There is little epidemiological evidence regarding the association of impaired glucose metabolism with recurrent cardiovascular events. We therefore examined potential sex differences in the effect of impaired fasting glucose (IFG) on recurrent cardiovascular disease (CVD) in a community-based study of survivors of a first acute myocardial infarction (MI). METHODS AND RESULTS: This report focuses on 1226 incident MI cases (28.4% women) discharged alive from area hospitals in the Western New York Acute MI Study (1996-2004). Deaths and underlying cause of death were determined via query of the National Death Index (Plus) Retrieval Program with follow-up through December 31, 2004. Outcomes reported included fatal or non-fatal coronary heart disease (CHD) or coronary revascularization surgery and total stroke. Traditional CHD risk factors and other explanatory variables were determined by clinical examination after the first acute event. Impaired fasting glucose was defined as fasting blood glucose between 100 and 125mg/dl. During a mean follow-up of 4.5 years, there were 91 recurrent events (26.1%) in women and 173 recurrent events (19.7%) in men. After multivariable adjustment, the hazard ratios for recurrent cardiovascular events were 1.96 (95% CI: 1.15-3.16) and 2.59 (1.56-4.30) in women with IFG and with diabetes, respectively, compared to normoglycemic women. Among men, neither IFG nor diabetes was independently related to risk of recurrence. CONCLUSIONS: In this study, IFG was a strong risk factor for recurrent cardiovascular events only among women. These results suggest that increased cardiovascular risk in MI survivors begins at lower glucose levels in women than men.

RESUMO

BACKGROUND AND AIMS: Glycoprotein 6 (GP6) is a platelet-specific collagen receptor implicated in the thrombotic pathway to acute myocardial infarction (AMI), but a possible genetic relationship between GP6 and AMI is poorly understood. We tested for the genetic association between AMI and single nucleotide polymorphisms (SNPs) in 24 loci, including GP6. METHODS AND RESULTS: We conducted a case-control study of AMI and GP6 in a community-based population (n = 652 cases, 625 controls). We also examined men and women separately and stratified the latter by use of hormone replacement therapy (HRT). Among both sexes, the strongest association was for a protective missense polymorphism (rs1163662) in the GP6 gene (OR = 0.70; Bonferroni-adjusted p < 0.05). SNPs in GP6 were also strongly associated with AMI among women who reported ever taking HRT, but not among women who never took HRT. Haplotype analyses were consistent with the single-SNP findings. CONCLUSIONS: In this sample of white non-Hispanic men and women, several SNPs in GP6 were significantly related to risk of AMI. Development of pharmacologic therapy directed towards platelet activity and thrombosis may reduce the incidence of AMI among at-risk groups.

RESUMO

An increased carotid intima-media thickness (IMT) is detectable in young subjects with parental history of premature myocardial infarction (PHPMI) or hypertension (PHH). In this study we evaluated if PHPMI and PHH exert a different influence on carotid IMT and if their conjunction produces additive effects. High-resolution B-mode ultrasonographic evaluation of common carotid artery IMT was acquired from 48 subjects without PHPMI and PHH (22 males, 26 females; mean age 22.1±4.9 years; controls), 24 age- (±1 year) and sex-matched subjects with PHH without PHPMI (PHH-positive/PHPMI-negative subjects), 24 age- and sex-matched subjects with PHPMI without PHH (PHH-negative/PHPMI-positive subjects) and 24 age- and sex-matched subjects with both PHPMI and PHH (PHH/PHPMI-positive subjects). Lipid profile, resting blood pressure, smoking behaviour and body mass index (BMI) were also assessed. Carotid IMT was smaller in controls (0.41±0.07mm) compared to PHH-positive/PHPMI-negative subjects (0.47±0.10, p=0.023), to PHH-negative/PHPMI-positive subjects (0.54±0.11, p<0.001) and to PHH/PHPMI-positive subjects (0.52±0.10mm, p<0.001). Carotid IMT was greater in PHH-negative/PHPMI-positive (p=0.006) and in PHH/PHPMI-positive (p=0.031) than in PHH-positive/PHPMI-negative subjects. No difference in carotid IMT was evident between PHH-negative/PHPMI-positive and PHH/PHPMI-positive subjects (p=0.549). In the comparison among subjects using multiple regression analysis, only PHPMI, age and BMI were independently associated with carotid IMT. In healthy young subjects with PHPMI and/or PHH, carotid IMT is increased. PHPMI is a stronger predictor of increased carotid IMT than PHH. PHH in conjunction with PHPMI does not add any further detrimental effect on carotid IMT.

RESUMO

Ethanol extract of mango seeds (EEMS) are composed of several polyphenolic compounds with considerable in vitro antioxidant activity that can be used in pig feed and may contribute positively to meat quality characteristics. The aim of this study was to evaluate the effect of EEMS as a source of antioxidants in growing-finishing pig diets on meat quality, lipid stability, sulfhydryl groups non-proteinaceous (SG-NP), total phenolic compounds, total antioxidant potential and total antioxidant activity of meat after 1 and 7 days of refrigeration storage. Thirty-two (60-day-old) barrows, weighing 20.20 ±â€¯1.34 kg, were used in a randomized block design consisting of eight animals with four treatment regimens. Treatments consisted of: Control = no dietary antioxidant; butylated hydroxytoluene (BHT) = diet with 200 ppm BHT; EEMS200 = diet with 200 ppm EEMS; EEMS400 = diet with 400 ppm EEMS. At 145 days of age and average weight of 95.47 ±â€¯6.19 kg, the animals were slaughtered and loin samples were collected and frozen before for qualitative analysis and evaluation of the effect of subsequent storage for 1 or 7 days at 8 °C on lipid stability, SG-NP, phenolic compounds, total antioxidant capacity and total antioxidant activity Meat from animals fed EEMS400 diet showed lower cooking loss (P < 0.0001) and higher non-protein sulfhydryl groups, phenolic compounds and total antioxidant activity at both 1 and 7 days of storage (P < 0.0001) compared to the other treatments. Greater antioxidant capacity was observed at 1 day storage in the meat of animals that consumed EEMS regardless of concentration when compared to the control group (P < 0.01). The dietary inclusion of EEMS to pig diets is more effective at 400 ppm in improving meat quality after cooking and antioxidant parameters of pork.
