Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ayahuasca (AYA) is a psychedelic brew used in religious ceremonies. It is broadly used as a sacred medicine for treating several ailments, including pain of various origins. AIM OF THE STUDY To investigate the antinociceptive effects of AYA and its mechanisms in preclinical models of acute and chronic pain in mice, in particular during experimental neuropathy. MATERIALS AND METHODS The antinociceptive effects of AYA administered orally were assessed in the following models of pain: formalin test, Complete Freund's Adjuvant (CFA)-induced inflammation, tail flick test, and partial sciatic nerve ligation model of neuropathic pain. Antagonism assays and Fos immunohistochemistry in the brain were performed. AYA-induced toxicity was investigated. AYA was chemically characterized. The antinociceptive effect of harmine, the major component present in AYA, was investigated. RESULTS AYA (24-3000 μL/kg) dose-dependently reduced formalin-induced pain-like behaviors and CFA-induced mechanical allodynia but did not affect CFA-induced paw edema or tail flick latency. During experimental neuropathy, single treatments with AYA (24-3000 μL/kg) reduced mechanical allodynia; daily treatments once or twice a day for 14 days promoted consistent and sustained antinociception. The antinociceptive effect of AYA (600 μL/kg) was reverted by bicuculline (1 mg/kg) and methysergide (5 mg/kg), but not by naloxone (5 mg/kg), phaclofen (2 mg/kg), and rimonabant (10 mg/kg), suggesting the roles of GABAA and serotonergic receptors. AYA increased Fos expression in the ventrolateral periaqueductal gray and nucleus raphe magnus after 1 h, but not after 6 h or 14 days of daily treatments. AYA (600 μL/kg) twice a day for 14 days did not alter mice's motor function, spontaneous locomotion, body weight, food and water intake, hematological, biochemical, and histopathological parameters. Harmine (3.5 mg/kg) promoted consistent antinociception during experimental neuropathy. CONCLUSIONS AYA promotes consistent antinociceptive effects in different mouse models of pain without inducing detectable toxic effects. Harmine is at least partially accountable for the antinociceptive properties of AYA.

Abstract
Zinc (Zn) is an essential micronutrient that plays a crucial role in fish development and physiology. This study aimed to evaluate the effects on growth and health in Nile tilapia (Oreochromis niloticus) supplemented with graded levels of zinc amino acid complex (Zn-AA) and subjected to transport stress. Nile tilapia (21.78 ± 0.17 g; (n = 12 fish per tank; stocking density of 1.045 kg- 3) were fed with 0, 25, 50, 75, or 100 mg Zn-AA kg- 1 (equivalent to 77.49, 102.69, 127.89, 153.09, or 178.29 mg Zn kg- 1) in extruded diets (280 g kg- 1 digestible protein; isoproteic and isocaloric) for 60 days. At the end of the experimental period, after growth performance measurements, the fish were transported by car for 3 h, and blood collection was performed. The linear regression showed that the best growth performance (final weight, final biomass, weight gain, specific growth rate, and feed intake) was found in fish fed with 100 mg Zn-AA kg diet- 1 (p < 0.05). The increased dietary Zn-AA increased linearly plasma triglyceride levels, hemoglobin, mean corpuscular hemoglobin, and leukocyte values and reduced plasma total protein, cholesterol (total and LDL), and aspartate aminotransferase levels (p < 0.05). According to quadratic regression, the highest plasma glucose and alanine aminotransferase values were found in the control group (p < 0.05). In conclusion, under the conditions of this study, 100 mg Zn-AA kg diet- 1 is recommended for Nile tilapia as it can improve their growth, metabolism, physiology, and immunity.

Abstract
BACKGROUND Sickle cell disease is a severe genetic disorder, and searching for therapeutic strategies is indispensable for prolonged and improved life for people affected by this condition. OBJECTIVE This qualitative systematic review aimed to highlight the therapeutic potential of omega- 3 (n-3) in people with sickle cell disease. METHODS The search was performed by combining sickle cell disease and n-3 descriptors in DeCS/ MeSH databases, including Scopus, PubMed, ScienceDirect, Web of Science, and Virtual Health Library. The risk of bias assessment in the primary studies was performed using the Cochrane risk of bias tool for randomized controlled trials. The evidence quality was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool. RESULTS From the 187 records identified, seven were selected for data collection. Based on the evidence, n-3 supplementation contributes to lower activation of pro-inflammatory biomarkers, improves the concentration of docosahexaenoic and eicosapentaenoic acids in the erythrocyte membrane, provides better hemostatic response, and helps in vaso-occlusive crisis, pain episodes, and hospitalization reduction. CONCLUSION The findings suggest that n-3 adjuvant therapy favors the clinical and general aspects of people with sickle cell disease.

Abstract
BACKGROUND Acute rejection remains one of the main complications in the first months after transplantation and may influence long-term outcomes. Tacrolimus has proven its usefulness in solid organ transplants and its monitoring through the application of pharmacokinetic concepts to optimize individual drug therapy. OBJECTIVE This research proposes to evaluate the tacrolimus pharmacokinetic parameters in patients suspected of acute kidney graft rejection under methylprednisolone pulse therapy. METHODS Eleven adult tacrolimus-treated renal recipients were selected from a prospective, single-arm, single-center cohort study, with suspicion of acute rejection although in use of methylprednisolone pulses therapy. They were followed up for three months posttransplantation, being tacrolimus trough serum concentrations determined using a chemiluminescent magnetic immunoassay, and pharmacokinetic parameters were estimated by using a nonlinear mixed-effects model implemented by Monolix 2020R1. A tacrolimus trough serum concentration range of 8 to 12 ng.mL-1 was considered therapeutic. RESULTS Six patients showed acute cellular rejection, and two of them in addition had an antibody- mediated rejection. Tacrolimus trough serum concentration was below the reference range in eight patients. Most patients showed a high tacrolimus concentration intrapatient and pharmacokinetic parameters variability. CONCLUSION The obtained pharmacokinetics parameters helped in understanding the kidney recipient patients' tacrolimus behavior, assisting in the improvement of individual drug therapy and reducing the risk of acute rejection episodes.

Abstract
Acute kidney injury (AKI) is the main cause of death from Bothrops snakebite. Although many studies have investigated the nephrotoxicity induced by other Bothrops species, no study has assessed the renal alterations induced by intramuscular (i.m.) injection of Bothrops leucurus venom. In this study, we evaluated the nephrotoxicity induced by B. leucurus venom by analyzing renal function and histology. Wistar rats were submitted to i. m. injection of B. leucurus venom or saline and divided into two groups: Control group (C), rats submitted to i. m. injections of saline, and B. leucurus group (Bl), rats submitted to i. m. injections of B. leucurus venom (1 mg/kg). After venom or saline injection, serum and urine were collected to measure creatinine, albumin, sodium, and potassium levels. The glomerular filtration rate (GFR), urinary flow urinary, creatinine/serum creatinine ratio, and albuminuria-urinary creatinine ratio were determined. All rats were euthanized 72 h following the injections, and the kidneys were removed for histology and immunohistochemical studies. B. leucurus experimental envenoming was accompanied by an increase of 236% in serum creatine kinase activity in the Bl group. The weights of the right and left kidneys were, respectively, 26 and 22% higher in rats of the Bl group than in control rats. Regarding renal function, the Bl group showed a decrease of 37% in GFR compared to control group. The rats of the Bl group also presented increased cortical (8.20 ± 1.35) and medullar (6.17 ± 2.00) tubulointerstitial lesion area when compared to control group (0.02 ± 0.00) (1.20 ± 0.73), respectively. The number of macrophages was also higher in the renal cortex (6.66 ± 0.06) and medulla (1.22 ± 0.10) of rats from the Bl group when compared to control rats (1.04 ± 0.55), (0.65 ± 0.10), respectively. Our results indicate that B. leucurus venom promoted significant histological and functional renal alterations following intramuscular inoculation, which simulates the majority of snakebites observed in the clinical practice.

Abstract
Introduction. In recent years, cholesterol has received interest in the study of infection due to evidence of a relationship between low plasma cholesterol levels and tuberculosis (TB).Hypothesis/Gap Statement. Plasma lipid profiles of serum amyloid A (SAA), apolipoprotein A-I and high-density lipoprotein cholesterol (HDL-C) are biomarkers associated with symptomatic TB patients.Objective. We aimed to evaluate plasma lipid profiles of apolipoprotein A-I, SAA and the size of HDL as biomarkers to diagnose symptomatic TB patients.Methodology. Patients with TB symptoms attending the Instituto Brasileiro para a Investigação da Tuberculose/Fundação José Silveira (IBIT/FJS) between September 2015 and August 2016 for diagnosis of TB were studied. From 129 patients, 97 were classified as pulmonary TB and 32 as negative-bacilloscopy (non-TB group). Medical history, fasting serum and plasma were obtained. Total cholesterol (TC), HDL-C, apolipoprotein A-I and SAA were measured by enzymatic or immunochemical reaction assays. HDL size was measured by laser light-scattering.Results. In TB patients, TC (147.0±37 vs. 168±44 mg dL-1), HDL-C (37±14 vs. 55±18 mg dL-1) and apolipoprotein A-I (102±41 vs. 156±47 mg dL-1) concentrations were lower (P<0.0001), while HDL particle size (10.16±1.02 vs. 9.62±0.67 nm) and SAA levels (280±36 vs. 19±8 mg L-1) were higher (P<0.0001). Using receiver-operating characteristic curve analysis for predicting TB, the cutoff values were <83.85 mg L-1 for SAA (sensitivity=96.88 %, specificity=78.43 %, P<0.0001), >44.50 mg dL-1 for HDL-C (sensitivity=75 %, specificity=72.16 %, P<0.001) and >118.5 mg dL-1 for apolipoprotein A-I (sensitivity=83.83 %, specificity=72.22 %, P<0.001).Conclusion. SAA, HDL-C and apolipoprotein A-I are associated with TB infection and could be used as laboratory biomarkers, especially in patients who are negative for alcohol-acid-resistant bacilli.

Abstract
Urinary tract infection (UTI) is one of the most common bacterial infections among humans. Urine culture is the gold standard diagnostic method for UTI; however, the dipstick test for nitrite is a widely used method signalling the presence of urinary nitrate-reducing bacteria. Unlike the gold standard, the dipstick test is easy to perform, while it is also less time-consuming and less expensive, and produces a result in a few minutes. This study investigates the sensitivity of the dipstick test for nitrite compared with the Griess test in urine samples from UTI caused by Enterobacterales species. We used the Griess test, which is the gold standard in nitrite measurement, to determine the sensitivity of the nitrite dipstick test. Semiquantitative urine culture was performed using standard procedures, and Enterobacterales identification was performed by manual conventional biochemical tests. In the first sample selection, 3 % (8/267) of urine samples suspected of UTI, analysed from March to April 2016, were nitrite-negative by dipstick test but positive for Enterobacterales in the urine culture. In the second sample selection, 5 % (2/44) of urine samples from October to December 2022 were also nitrite-negative but showed urine Enterobacterales isolation. All nitrite-negative dipstick results were consistent with the Griess test. Escherichia coli was the most prevalent bacterium, followed by Klebsiella pneumoniae, independent of sample selection. The dipstick test is a safe alternative for investigating nitrite in urine samples. We believe that the cause of nitrite-negative results is a lack of dietary nitrate, dilution of urine and exogenous interference (e.g. ascorbic acid). These findings support the idea that standard urine culture is necessary to rule out UTI.

Abstract
BACKGROUND HIV infection affects millions of people globally. Currently, several drugs have brought an improvement in the quality and life expectancy of these individuals, but this therapy is accompanied by several adverse effects. OBJECTIVE To conduct a systematic review with studies examining the relationship between antiretroviral therapy (ART) uses and secondary dyslipidemia. METHODS The review followed the criteria defined by PRISMA. Only articles that completely evaluated the lipid profile were included, which consisted of total cholesterol (TC), triglycerides (TG) and LDL cholesterol (LDL-c), HDL cholesterol (HDL-c). RESULTS It was observed that the use of nucleoside and non-nucleoside reverse transcriptase inhibitor (NNRTI and NNRTI respectively) drugs and protease inhibitors are the most used in ART and are associated with changes in lipid profiles. The main changes observed were increases in TC, TG, and LDL-c in addition to a decrease in HDL-c. These patients had a higher risk of developing cardiovascular disease not only due to the use of therapy but also due to the presence of other comorbidities evaluated in these studies, such as obesity, diabetes, and hypertension. The increase in age, the difference between genders, CD4 T-cell count, and viral load, were observed as risk factors for worsening dyslipidemia. CONCLUSION Based on the present study, it was concluded that anti-HIV therapy is associated with dyslipidemia, which may be the primary cause or not, and is usually associated with several metabolic disorders that may in themselves aggravate this condition.

Abstract
Background: Green tea, obtained from the plant Camellis sinensis, is one of the oldest drinks in the world and contains numerous bioactive compounds. Studies have demonstrated the efficacy of green tea in preventing obesity and cardiovascular diseases that may be related to the reduction of lipid levels. Aim: This study aimed to evidence, through a systematic review, the therapeutic potential of green tea on the lipid profile in preclinical studies in obese animals and clinical studies in obese individuals. Methods: This systematic review follows the recommendations of the preferred report items for systematic reviews and meta-analyses. The electronic databases, PubMed (Medline), Science Direct, Scopus, and Web of Science were consulted. Articles from January 2009 to December 2019 were selected. Results: This search resulted in twenty-nine articles were included cirtically reviewed. In experimental studies, green tea administration has been shown to reduce total cholesterol, triglycerides and low-density lipoprotein cholesterol in animals exposed to obesity-inducing diet. In humans' studies green tea was not shown to be effective for obese lipid control. Because supplementation with green tea extract reduced total cholesterol, triglycerides, low-density lipoprotein for three months at a specific dose. Conclusion: Therefore, green tea appears to act as a protective agent for dyslipidemia in obesity-induced animals. In human studies, green tea has not been shown to be effective in controlling obese lipids.

Abstract
Introduction. Sickle cell disease (SCD) children have a high susceptibility to pneumococcal infection. For this reason, they are routinely immunized with pneumococcal vaccines and use antibiotic prophylaxis (AP).Hypothesis/Gap Statement. Yet, little is known about SCD children's gut microbiota. If antibiotic-resistant Enterobacterales may colonize people on AP, we hypothesized that SCD children on AP are colonized by resistant enterobacteria species.Objective. To evaluate the effect of continuous AP on Enterobacterales gut colonization from children with SCD.Methodology. We analysed 30 faecal swabs from SCD children on AP and 21 swabs from children without the same condition. Enterobacterales was isolated on MacConkey agar plates and identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) (bioMérieux, Marcy l'Etoile, France). We performed the antibiogram by Vitek 2 system (bioMérieux, Marcy l'Etoile, France), and the resistance genes were identified by multiplex PCR.Results. We found four different species with resistance to one or more different antibiotic types in the AP-SCD children's group: Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii, and Citrobacter farmeri. Colonization by resistant E. coli was associated with AP (prevalence ratio 2.69, 95 % confidence interval [CI], 1.98-3.67, P<0.001). Strains producing extended-spectrum β-lactamases (ESBL) were identified only in SCD children, E. coli, 4/30 (13 %), and K. pneumoniae, 2/30 (7 %). The ESBL-producing Enterobacterales were associated with penicillin G benzathine use (95 % CI, 22.91-86.71, P<0.001). CTX-M-1 was the most prevalent among ESBL-producers (3/6, 50 %), followed by CTX-M-9 (2/6, 33 %), and CTX-M-2 (1/6, 17 %).Conclusion. Resistant enterobacteria colonize SCD children on AP, and this therapy raises the chance of ESBL-producing Enterobacterales colonization. Future studies should focus on prophylactic vaccines as exclusive therapy against pneumococcal infections.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Physalis angulata is an herb found in tropical and subtropical regions of the world; it is widely applied in popular medicine due to the therapeutic properties of the whole plant and its parts. Extracts and infusions of this plant have been extensively applied in folk medicine worldwide to treat inflammatory and immune-mediated diseases, including oral inflammatory conditions such as sore throat and gingivitis. AIM OF THE STUDY The present study was designed to investigate the protective effects of the ethanolic extract of P. angulata (EEPA) in a murine model of chronic periodontitis, aiming to corroborate its traditional use as an anti-inflammatory and immunomodulatory agent, and to point out possible mechanisms involved in these effects. MATERIALS AND METHODS EEPA was obtained from the stems of P. angulata collected in Belém (PA, Brazil). Chronic periodontitis was induced in male C57BL/6 mice by 12 administrations of lipopolysaccharide (LPS; 20 μg/1μL) into the gingival papilla in the course of 28 days. Starting from the 15th day after the first LPS injection, mice were daily treated with EEPA (50 or 100 mg/kg), nimesulide (25 mg/kg, reference drug), or vehicle by oral route for 14 days. At the end of the experimental period, alveolar bone loss was evaluated along with the gingival expression of biomarkers of periodontitis and cytokines by RT-q-PCR and ELISA. Hematological and biochemical parameters suggestive of systemic toxicity were also evaluated. The transcriptional activity of NF-κB was investigated using the luciferase assay in macrophages. RESULTS Mice with chronic experimental periodontitis suffered alveolar bone loss that was prevented by the treatment with EEPA (50 or 100 mg/kg) or nimesulide (25 mg/kg). EEPA (50 and 100 mg/kg) and nimesulide (25 mg/kg) reduced mRNA levels of MMP-9 mRNA, but not of TIMP-1 in gingival tissue of periodontitis-induced mice. Both treatments also reduced the production of the pro-inflammatory cytokines IL-1β and IL-6. The treatment with EEPA (100 mg/kg) increased the production of the anti-inflammatory cytokine TGF-β. No hematological or biochemical alterations were caused by the daily treatment with EEPA. In vitro luciferase assay suggested that a putative mechanism of EEPA is reducing the transcriptional activity of NF-κB. CONCLUSIONS EEPA exhibited a disease-modifying effect in the chronic experimental periodontitis, along with unidentifiable systemic toxicity. This work corroborates the traditional use of P. angulata in oral inflammatory conditions and provides mechanistic hypotheses to explain its therapeutic effects.

Abstract
Naltrexone (NTX) is an opioid antagonist that inhibits cell proliferation in vivo when administered in low doses. Naltrexone in low doses are able to reduce tumor growth by interfering with cell signalling as well as by modifying the immune system. It acts as an opioid growth factor receptor (OGFr) antagonist and the OGF-OGFr axis is an inhibitory biological pathway present in human cancer cells and tissues, being a target for treatment with naltrexone low-dose (LDN). Clinical trials have proposed a unique mechanism(s) allowing LDN to affect tumors. LDN shows promising results for people with primary cancer of the bladder, breast, liver, lung, lymph nodes, colon and rectum. This short review provides further evidence to support the role of LDN as an anticancer agent.

Abstract
Glycidyl methacrylate (GMA; CAS no. 106-91-2) is a chemical monomer used in the manufacture of dental resins, can coatings and polymers. GMA has demonstrated toxicity to the ocular, digestive, respiratory and dermal systems. Human exposure occurs mainly in the workplace, but it can also happen through food. Although there were no available data on carcinogenicity of GMA, carcinogenic potential in the nasal cavity is highly expected. Further studies are needed to assess GMA exposure in humans. This study provides an alert of GMA human exposure and its genotoxic and carcinogenic potential.

Abstract
Objective Acute tubular necrosis (ATN) is a frequent cause of acute kidney injury (AKI). In patients with nephrotic syndrome (NS), AKI demands the differential diagnosis between ATN and rapidly progressive glomerulonephritis. In some cases, conclusive diagnosis is possible only by kidney biopsy. We aimed to study the potential use of urine cytology in the differential diagnosis between ATN and proliferative glomerular lesion in patients with NS. Results Cell size analysis showed a higher proportion of small cells and a lower proportion of large cells in the urine of patients with AKI. Cells phenotypes were easily defined using cytological preparations. Leukocytes were found to be a primary classifier of NS groups, with higher number in patients with AKI and patients with proliferative glomerular lesions. Although renal biopsy is still required for confirmative diagnosis, our data suggests that urinary cytology can be readily performed and support the differential diagnosis between proliferative glomerular lesion and ATN in patients with NS and AKI.

Abstract
AIM This study aimed to verify the correlation between murine measurements and retroperitoneal adipose tissue in rats exposed to the high-fat diet. Material and methods: Wistar male adult rats, descendants of mothers who consumed a high-fat diet during pregnancy and lactation and fed the same diet after weaning were used. At 60 days of life, body weight, longitudinal axis and waist circumference (WC) were measured. The Body Mass Index (BMI) and the Lee Index were calculated for a posterior analysis of the correlation with the amount of retroperitoneal adipose tissue dissected on the same day. For analysis of the data, the Pearson correlation test was used, considering statistical significance for p <0.05. Results: Body weight had a weak correlation (r= 0.31; p= 0.38) with retroperitoneal adipose tissue. While the longitudinal correlated moderately and negative (r= -0.40; p= 0.25). Abdominal circumference (r= 0.62; p= 0.05), body mass index (r= 0.61; p= 0.03) and Lee (r= 0.69; p= 0.03) correlated moderately and positively with adipose tissue. Conclusion: Among the measured murine measurements, weight and longitudinal axis were not good indicators to represent accumulation of retroperitoneal adipose tissue in rats. However, Lee's index seems to be the best murine marker to diagnose the accumulation of retroperitoneal fat. BMI, CA and Lee index were murine parameters with higher correlation.

Abstract
Abstract Interventions via the Internet are promising regarding the promotion of healthy habits among youth. The objective of this study was to evaluate the effect of an adapted version of StayingFit to promote healthy eating habits and the measurement adequacy of anthropometric markers among adolescents. A web school-based 12-month cluster-randomized controlled trial examining 7th to 9th grade students was conducted in twelve schools in Salvador, Bahia, Brazil. The schools’ students were randomly distributed into the intervention and control groups. The intervention group participated in StayingFit, an online program designed to encourage and guide healthy eating habits and control body weight. Data on food consumption, anthropometry, physical activity level, and sedentary behavior were collected from all of the students at the beginning of and after the 12-month study. Demographic and socioeconomic data were collected at baseline. The baseline data indicated high rates of overweight (14.4% overweight and 8.5% obese), insufficiently active (87.6%), and sedentary (63.7%). Furthermore, few adolescents regularly consumed fruits (18.8%) and vegetables/legumes (16.4%). Generalized estimating equations (GEEs) were used to evaluate the effect of the intervention. At the end of the follow-up period, students in the intervention group had a 43% increased chance of regularly consuming beans (OR = 1.43, 95% CIs = 1.10–1.86) and a 35% decreased chance of regularly consuming soft drinks (OR = 0.65, 95% CIs = 0.50–0.84). No differences were found between the groups studied with regard to the anthropometric parameters. Despite these modest results, the implementation of a web intervention can be beneficial and help promote positive changes in adolescent eating habits.

Abstract
Objective: To determine the frequency of active smoking among patients with asthma and individuals without asthma by self-report and urinary cotinine measurement. Methods: This was a cross-sectional study conducted in the city of Salvador, Brazil, and involving 1,341 individuals: 498 patients with severe asthma, 417 patients with mild-to-moderate asthma, and 426 individuals without asthma. Smoking status was determined by self-report (with the use of standardized questionnaires) and urinary cotinine measurement. The study variables were compared with the chi-square test and the Kruskal-Wallis test. Results: Of the sample as a whole, 55 (4.1%) reported being current smokers. Of those, 5 had severe asthma, 17 had mild-to-moderate asthma, and 33 had no asthma diagnosis. Of the 55 smokers, 32 (58.2%) were daily smokers and 23 (41.8%) were occasional smokers. Urinary cotinine levels were found to be high in self-reported nonsmokers and former smokers, especially among severe asthma patients, a finding that suggests patient nondisclosure of smoking status. Among smokers, a longer smoking history was found in patients with severe asthma when compared with those with mild-to-moderate asthma. In addition, the proportion of former smokers was higher among patients with severe asthma than among those with mild-to-moderate asthma. Conclusions: Former smoking is associated with severe asthma. Current smoking is observed in patients with severe asthma, and patient nondisclosure of smoking status occurs in some cases. Patients with severe asthma should be thoroughly screened for smoking, and findings should be complemented by objective testing.

Abstract
Several changes occur in lipid metabolism during gestation due to hormonal and metabolic changes, which are essential to satisfy the nutritional demands of the maternal-fetal unit development. The gestation shows two distinct periods that begin with fat accumulation, mainly in maternal adipose tissue, and the late phase, characterized by accelerated catabolism, with the increase of fatty acids in the circulation that causes hyperlipidemia, especially the one characterized as hypertriglyceridemia. Maternal hyperlipidemia may be associated with the development of maternal-fetal complications (preterm birth, preeclampsia, vascular complications) and the development of long-term cardiovascular disease. The cardiovascular risk may not only be related to lipoproteins cholesterol content, but also to the number and functionality of circulating lipoprotein particles. This review reports the major changes that occur in lipoprotein metabolism during pregnancy and that are associated with the development of dyslipidemias, lipoprotein atherogenic phenotype, and maternal-fetal unit complications.

Abstract
AIM Obesity during pregnancy is one of the most established risk factors for negative long-term programming. The aim of the present study was to investigate the effects of maternal consumption of a high-fat diet during pregnancy and lactation on the weight gain, visceral adipose tissue and cholesterolemia in neonatal rats. METHODS Wistar rats were divided into two groups according to the mother's diet during pregnancy and lactation: Control group (CG, n = 12) were the offspring of rats fed a standard diet (4% lipid) and the Test group (TG, n = 12) were pups rats fed on a high fat diet (23% lipid). The weight of the animals was measured on alternate days until the 22nd day of life, when collected visceral adipose tissue and blood were collected for biochemical analysis. For statistical analysis the Student t test, Sidak´s teste and two way ANOVA was used, with p <0.05. RESULTS the test group showed differences in weight gain, visceral adipose tissue and higher cholesterol. CONCLUSION a maternal exposure to a high-fat diet during pregnancy and lactation can promote changes in weight gain, hypercholesterolemia and an increase in adipose tissue in neonatal rats.

Abstract
BACKGROUND Obesity is associated with numerous cardiac complications, including arrhythmias, cardiac fibrosis, remodeling and heart failure. Here we evaluated the therapeutic potential of mesenchymal stromal cells (MSCs) and their conditioned medium (CM) to treat cardiac complications in a mouse model of high-fat diet (HFD)-induced obesity. METHODS After obesity induction and HFD withdrawal, obese mice were treated with MSCs, CM or vehicle. Cardiac function was assessed using electrocardiography, echocardiography and treadmill test. Body weight and biochemical parameters were evaluated. Cardiac tissue was used for real time (RT)-polymerase chain reaction (PCR) and histopathologic analysis. RESULTS/DISCUSSION Characterization of CM by protein array showed the presence of different cytokines and growth factors, including chemokines, osteopontin, cystatin C, Serpin E1 and Gas 6. HFD-fed mice presented cardiac arrhythmias, altered cardiac gene expression and fibrosis reflected in physical exercise incapacity associated with obesity and diabetes. Administration of MSCs or CM improved arrhythmias and exercise capacity. This functional improvement correlated with normalization of GATA4 gene expression in the hearts of MSC- or CM-treated mice. The gene expression of connexin 43, troponin I, adiponectin, transforming growth factor (TGF) β, peroxisome proliferator activated receptor gamma (PPARγ), insulin-like growth factor 1 (IGF-1), matrix metalloproteinase-9 (MMP9) and tissue inhibitor of metalloproteinases 1 (TIMP1) were significantly reduced in MSCs, but not in CM-treated mice. Moreover, MSC or CM administration reduced the intensity of cardiac fibrosis. CONCLUSION Our results suggest that MSCs and CM have a recovery effect on cardiac disturbances due to obesity and corroborate to the paracrine action of MSCs in heart disease models.

Abstract
Background Sepsis is an illness with a high morbidity for which no effective treatment exists. Its treatment has a high cost because it usually requires an intensive care unit and expensive antibiotics. The present study focus in the production of reactive oxygen species in the early stages of sepsis. This study aimed at investigating the production of reactive oxygen specie during the inflammatory response in patients with sepsis. Methods Reactive oxygen specie production and insoluble myeloperoxidase obtained from fresh whole blood were measured by photon counting chemiluminescence in the blood of 18 septic patients and 12 healthy individuals. Modified red blood cells were evaluated by staining of blood smears. The production of reactive oxygen species by macrophages and polymorphonuclear leukocytes put into contact with modified red blood cells were also assessed by photon counting chemiluminescence. Results The appearance of oxidatively modified erythrocytes, which is an evidence of oxidative stress, was supported by the detection of reactive oxygen species and insoluble myeloperoxidase in the whole blood of all septic patients. Peroxynitrite was the main reactive oxygen species found in the whole blood. Oxidatively modified erythrocytes activated phagocytic cells in vitro, leading to the considerable production of free radicals. Conclusion It was found that sepsis led to a high oxidative stress and to extensive modification of erythrocytes. It is proposed that a positive feedback mechanism, involving the activation of circulating leukocytes by these modified erythrocytes would maintain the pro-oxidative state even after the disappearance of bacteria.

Abstract
OBJECTIVE Diabetes mellitus is the main cause of Charcot neuroarthropathy and is clinically classified as follows: Charcot foot, acute Charcot foot (ACF) when there is inflammation, and inactive Charcot foot when inflammatory signs are absent. The aim of this study was to identify the risk factors for ACF in patients with type 2 diabetes mellitus. MATERIALS AND METHODS A matched case-control study was conducted to assess the factors associated with acute Charcot foot from February 2000 until September 2012. Four controls for each case were selected 47 cases of ACF and 188 controls without ACF were included. Cases and controls were matched by year of initialization of treatment. Conditional logistic regression was used to estimate matched odds ratios (ORs) and 95% confidence intervals (95% CIs). RESULTS In multivariate analysis, patients having less than 55 years of age (adjusted OR = 4.10, 95% CI = 1.69 - 9.94), literate education age (adjusted OR = 3.73, 95% CI = 1.40 - 9.92), living alone (adjusted OR = 5.84, 95% CI = 1.49 - 22.86), previous ulceration (adjusted OR = 4.84, 95% CI = 1.62 - 14.51) were at increased risk of ACF. However, peripheral arterial disease (adjusted OR = 0.16, 95% CI = 0.05 - 0.52) of 6.25 (1.92 - 20.0) was a protective factor. DISCUSSION The results suggest that PCA in type 2 diabetes primarily affects patients under 55 who live alone, are literate, and have a prior history of ulcers, and that peripheral arterial disease is a protective factor.

Abstract
AIM considering the frequent consumption of fat-rich diets by women of reproductive age, the aim of the present study was to investigate the effects of maternal consumption of a high-fat diet during the perinatal and/ or post-weaning period on the liver parameters and lipid metabolism of young rats. METHODS Wistar female rats were fed a high-fat (H) or control (C) diet during pregnancy and lactation. The offspring were allocated to four groups: Control Control (CC, n = 11), offspring fed a control diet after weaning; Control High-fat (CH, n = 10), offspring fed a high-fat diet after weaning; High-fat High-fat (HH, n = 10), offspring of mothers H fed a high-fat diet after weaning; and High-fat Control (HC, n = 9), offspring of mothers H fed with control diet after weaning. RESULTS AND DISCUSSION the food intake did not differ among the groups, however, the relative weight of the adipose tissue was higher in animals from the HC, HH and CH groups (p ≤ 0.005). Liver steatosis was found in the CH and HH animals, which also exhibited hypercholesterolemia (p ≤ 0.05). The levels of the liver enzymes alanine aminotransferase (ALT) and gamma-glutamyl transpeptidase (GGT) were higher in the HH group, and the LDL level was higher in the CH group compared to the CC. The consumption of an obesogenic diet during critical periods of development may contribute to the occurrence of visceral obesity, liver steatosis and hypercholesterolemia in adult rats, even in the absence of changes in dietary intake.

Abstract
AIM to evaluate the effects of a protocol promoting adequate and healthy eating on adolescent health parameters. METHODS this controlled intervention study was conducted for 9 months, with the participation of adolescents enrolled in two schools (intervention/control) located in a poor neighbourhood in the city of Salvador (Bahia), Brazil. For the intervention school, activities promoting adequate and healthy eating were designed based on the Food Guide for the Brazilian Population (Guia Alimentar para a População Brasileira). Students underwent biochemical, sexual maturation and anthropometric tests at baseline and at the end of the 9-month period. In addition, students answered a questionnaire on food consumption, physical activity and sedentary behaviour. Information on the socioeconomic status of their family was also obtained. Generalized Estimating Equation (GEE) analysis was chosen to evaluate the associations of interest. RESULTS students under intervention presented decreases of 7.64 mg/dL in mean total cholesterol (TC) (p = 0.009) and 7.77 mg/dL in mean low-density lipoprotein cholesterol (LDLc) (p = 0.003) and increases of 18% in legume consumption (odds ratio [OR] = 1.18; 95% confidence interval [CI] 1.03-1.37) and 17% in vegetable consumption (OR = 1.17; 95%CI 1.01-1.35) compared with students who did not undergo intervention. No differences were observed in the anthropometric parameters analysed. CONCLUSION the results showed a positive effect of activities promoting adequate and healthy eating on reducing TC and LDLc and on increasing the consumption of vegetables and legumes, evidencing that the intervention model was able to prevent and/or treat cardiovascular risk factors in adolescents.

Abstract
OBJECTIVE This study aimed to identify the seroprevalence of celiac disease in adolescents from public schools in the city of Salvador, Bahia. METHODS This was a cross-sectional study with probabilistic sample of 1,213 adolescents, aged 11 to 17 years old, of both genders. The body mass index was used to determine the participants' nutritional status based on the percentiles for age and gender recommended by the World Health Organization. Measurement of the anti-human transglutaminase immunoglobulin A (anti-tTG-IgA) antibody was established as the specific screening test for celiac disease, which involved an enzyme-linked immunosorbent assay (ELISA). Descriptive analysis was performed using proportions and means (standard deviation). RESULTS The female gender prevailed in the sample, and most of the participants had normal weights. The anti-tTG-IgA antibody was positive in 6/1,213 (0.49%) adolescents. CONCLUSION The seroprevalence of celiac disease was 0.49% in the investigated adolescents. Further studies are necessary to establish the prevalence of celiac disease in this age range.

Abstract
Through the integration of chemical, biochemical and morphological analyses, this study investigated the effects of multiple pollutants on environmental biomarkers, such as gill histopathological changes and hematological and biochemical parameters, in Oreochromis niloticus exposed to four sites in the Jacuipe and Subaé rivers over seven days. Sediment analyses identified Sapelba as the most contaminated site, followed by Oliveira de Campinhos, Santo Amaro and Jacuípe. Water analyses revealed aluminum, iron and manganese at all sites. Aluminum and other metal were also detected in the gills of fishes. Fish exposed to the Sapelba site exhibited significant necrosis formation, as well as higher hematological parameters and trend to increase of cortisol levels. However, filament epithelium proliferation was higher at the Oliveira de Campinhos and Santo Amaro sites, at which the lowest levels of the hematological variables were observed. Multivariate analysis grouped some gill histopathological changes together, such as epithelial detachment with edema and lamellar epithelial proliferation with the lamellar fusion of adjacent filaments, revealing relationships among them. Positive associations were identified between sediment contamination and necrosis and cortisol, while water contamination was related with filament epithelium proliferation, aneurism, lamellar fusion and several hematological parameters. Furthermore, relationships between blood parameters and gill histopathological changes demonstrated a joint physiological response that may have resulted from environmental variables such as dissolved oxygen. The results exhibited the direct influence of xenobiotics on these biomarkers but also highlighted the need to consider the complexity of environmental factors to optimize the adoption of these environmental predictive tools.

Abstract
Cardiovascular diseases represent the main cause of morbidity and mortality in the world and are epidemic events involving the atherosclerosis and coronary artery disease in particular. There are a wide variety of factors and markers associated with the development and aggravation of these diseases, including atherosclerosis. Subclinical Atherosclerosis can be determined by serum inflammatory markers present in the atherogenic process. Such markers can take a direct or indirect indicator role on atherosclerotic cardiovascular disease. The extracellular matrix metalloproteinases are biomarkers closely related into modifying and remodeling of vascular wall and other tissues and can represent predictive value patterns to support diagnosis. This review discusses the function and types of matrix metalloproteinases and its use as an indicator of support for the diagnosis of atherosclerosis.

Abstract
Objetivos: avaliar a capacidade dos indicadores antropométricos e pontos de corte na predição da síndrome metabólica (SM) em crianças e adolescentes. Métodos: estudo transversal, envolvendo amostra probabilística de 879 crianças e adolescentes de ambos os sexos. Dados metabólicos, antropométricos e sociodemográficos foram coletados. Para diagnóstico da SM, foi utilizada a definição modificada do National Cholesterol Education Program's Adult Treatment Panel III (NCEP-ATP III). A capacidade dos indicadores antropométricos na predição do SM foi avaliada por meio da curva Receiver Operating Characteristic (ROC). Resultados: a prevalência de SM foi de 6,6%. Na predição da SM, a área sob a curva ROC foi de 0,79 (0,72; 0,85) para índice de massa corporal (IMC), de 0,79 (0,73; 0,85) para circunferência da cintura (CC) e de 0,83 (0,78; 0,89) para circunferência da cintura corrigida pela estatura (RCE). O ponto de corte identificado para RCE na predição da SM foi de 0,448 (ambos os gêneros). Conclusões: todos os indicadores antropométricos utilizados, com pequena superioridade da RCE, foram bons preditores da SM. O ponto de corte identificado para RCE na predição da SM aproxima-se daquele proposto por alguns autores como universal. Sugere-se o uso deste índice dado a sua simples operacionalidade em estudos clínicos e epidemiológicos como preditor da SM.

Abstract
Bergenin (1) is a C-glucoside of 4-O-methylgallic acid with known antiarthritic activity attributed to modulation of cytokine production. The present study was undertaken to evaluate whether 1 has antinociceptive properties in models of inflammatory pain and to investigate its possible mechanisms of action. Pretreatment with 1 (12.5-100 mg/kg, ip) produced a dose-related inhibition of acetic acid-induced writhing in mice. Furthermore, treatment with 1 (50 and 100 mg/kg) inhibited both the early and late phases in a formalin test. In addition, 1 (50 and 100 mg/kg, ip) inhibited mechanical hyperalgesia, edema, and paw production of hyperalgesic cytokines (TNF-α and IL-1β) induced by complete Freund's adjuvant. However, the local production of IL-10, an anti-inflammatory cytokine, was not altered by 1 (100 mg/kg, ip). Treatment with 1 produced a similar profile of antinociception in wild-type and IL-10-deficient mice. Mice treated with 1 did not show any motor performance alterations or apparent systemic toxicity. The results presented herein demonstrate that bergenin has consistent antinociceptive and anti-inflammatory properties, acting by the inhibition of IL-1β and TNF-α production, and suggest its potential for the control of inflammatory pain.

Abstract
7-Hydroxycoumarin (umbelliferone, 1), the main metabolite of coumarin, has been reported to produce potent antinociceptive effects in animal models of pain. However, the biochemical events involved in antinociception mediated by 1 are currently not well understood. In the present study, the mechanisms by which 1 exerts its pharmacological actions were investigated. Acute pretreatment of mice with 1 produced a long-lasting antinociceptive effect against complete Freund's adjuvant (CFA)-induced hyperalgesia. The subchronic administration of 1 inhibited CFA-induced hyperalgesia and paw edema, while it did not cause any apparent toxicity. Another set of experiments showed that 1 inhibited carrageenan-induced mechanical hyperalgesia, but not mechanical hyperalgesia induced by prostaglandin E(2) (PGE(2)), suggesting that it acts upstream of PGE(2.) Treatment with 1 was able to prevent the plantar tissue neutrophil influx induced by local inflammatory stimuli. In addition, 1 exhibited inhibitory effects on the release of hyperalgesic cytokines (TNF-α and IL-1β) and the production of PGE(2), a directly acting hyperalgesic mediator. The present results suggest that the antinociceptive effect of 1 is correlated with the inhibition of neutrophil migration, cytokine release, and PGE(2) production and are supportive of the further investigation of the therapeutic potential of 1 to control inflammatory pain.
