Abstract
Trypanosoma cruzi is a parasite with a high capacity to adapt to the host. Animal models have already demonstrated that the tropism of this parasite occurs not only in cardiac/digestive tissues but also in adipose tissue (AT). That said, the consequences ofT. cruziinfection for AT and the implications of treatment with Benzonidazole in this tissue are under discussion. Here, we tested the hypothesis that T. cruzi infection in adipose tissue upon treatment with Benzonidazole (Bz) and the interaction of mononuclear immune cells (PBMC) influences the relative expression of ACAT1, FASN, and PNPLA2 genes. Thus, stem cells derived from adipose tissue (ADSC) after adipogenic differentiation were indirectly cultivated with PBMC after infection with the T. cruzi Y strain and treatment with Bz. We use the TcSAT-IAM system and RT-qPCR to evaluate the parasite load and the relative quantification (ΔCt) of the ACAT1, FASN, and PNPLA2 genes. Our results demonstrate that treatment with Bz did not reduce adipocyte infection in the presence (p-value: 0.5796) or absence (p-value: 0.1854) of cultivation with PBMC. In addition, even though there is no statistical difference when compared to the control group (AT), T. cruzi induces the FASN expression (Rq: 14.00). However, treatment with Bz in AT suggests the increases of PNPLA2 expression levels (Rq: 12.58), even in the absence of T. cruzi infection. During indirect cultivation with PBMC, T. cruzi smooths the expression of PNPLA2 (Rq: 0.824) and instigates the expression of ACAT1 (Rq: 1.632) and FASN (Rq: 1.394). Furthermore, the treatment with Bz during infection induces PNPLA2 expression (Rq: 1.871), maintaining FASN expression levels (Rq: 1.334). Given this, our results indicate that treatment with Benzonidazole did not decrease T. cruzi infection in adipose tissue. However, treating the adipocyte cells with Bz during the interaction with PBMC cells influences the lipid pathways scenario, inducing lipolytic metabolism through the expression of PNPLA2.

Abstract
BACKGROUND Biochemical markers and imaging tests have been used with the aim of stratifying the risk and detecting atrial fibrosis. Speckle-tracking echocardiography (STE) is used for the detection of atrial fibrosis and Gal-3 provides an important prognostic value. The objective of the study was to assess the association between atrial fibrosis markers and serum levels, genetic polymorphisms and genic expression of galectin-3. METHODS 206 patients with permanent AF and 70 patients with paroxysmal AF were included in the study. Real time PCR (TaqMan) system was used to study SNPs rs4652 and 4644 of the gene LGALS3. Serum levels of Gal-3 were determined by ELISA and STE was performed to assess fibrosis. RESULTS Mean age of individuals with permanent AF was 66.56 ± 12 years. As for the echocardiography results, those patients showed an decrease in the following parameters peak atrial longitudinal strain (PALS) (p = 0.002) when compared to the same parameters from the paroxysmal AF group of patients. There was a correlation between serum levels of Gal-3 and PALS in the group of patients with permanent AF; the lower the levels of gal-3, the lower the LA strain (r = 0.24; p = 0.01). CONCLUSIONS Echocardiographic findings showed association with the groups, and with serum levels of Gal-3 in patients with permanent AF. The distribution of allelic and genotypic frequencies, and of the haplotypes of polymorphism LGALS3 rs4652 and rs4644 did not present statistical variation, which suggests that those SNPs are not associated with the AF clinical forms (permanent and paroxysmal).

Abstract
BACKGROUND MicroRNAs are involved in gene regulation in several common liver diseases and may play an essential role in activating hepatic stellate cells. The role of these post-transcriptional regulators in schistosomiasis needs to be further studied in populations from endemic areas for a better understanding of the disease, the development of new therapeutic approaches, and the use of biomarkers for the prognosis of schistosomiasis. AREAS COVERED We performed a systematic review to describe the main human microRNAs identified in non-experimental studies associated with aggravation of the disease in people infected with Schistosoma mansoni (S. mansoni) and Schistosoma japonicum (S. japonicum). Structured searches were carried out in PubMed, Medline, Science Direct, Directory of Open Access Journals, Scielo, Medcarib, and Global Index Medicus databases without time and language restrictions. This is a systematic review following the guidelines of the PRISMA platform. EXPERT OPINION The miR-146a-5p, miR-150-5p, let-7a-5p, let-7d-5p, miR-92a- 3p, and miR-532-5p are associated with liver fibrosis in schistosomiasis caused by S. japonicum, revealing that these miRNAs that have been shown to be associated with liver fibrosis are good targets for new studies that evaluate their potential as a biomarker or even treating liver fibrosis in schistosomiasis.

Abstract
OBJECTIVE Identify original articles that analyzed the diagnostic value of miR-21 in hepatocellular carcinoma without language restriction or publication date. METHODOLOGY We performed structured searches on PubMed, Web of Science, VHL, and EMBASE. The Standard Quality Assessment Criteria for Evaluating Primary Research Papers from a Variety of Fields was used to assess the quality of each study. Random effect models were used to study heterogeneity, evaluated based on the Higgins I2 statistic. RESULTS 12 articles were evaluated and contained raw data from 1,329 individuals, of which 617 had HCC, 473 were healthy, and 239 had Chronic liver disease. The combined sensitivity and combined specificity of miR-21 for diagnosing HCC were, respectively, 0.83(95% CI:0.78-0.89) and 0.85(95% CI:0.80-0.90). The sensitivity and specificity, in that order, by type of control were 0.81 (95% CI: 0.71-0.91) and 0.88 (95% CI: 0.82-0.93) for CLDs and 0.86(95% CI: 0.81-0.91) and 0.83(95% CI:0.74-0.91) for Healthy controls. CONCLUSION miR-21 has a moderate overall performance in diagnosing HCC and may serve as a potential non-invasive marker for this early-stage disease. Thus, it may contribute to complementing the results of alpha-fetoprotein in the diagnosis and help to detect HCC at an earlier stage, increasing the survival chances of these patients.

Abstract
In HIV-infected patients, antiretroviral therapy (ART) is associated to adipose tissue redistribution known as lipodystrophy (LD). This study aimed at verifying the association between the polymorphism of the MMP1 gene (rs1799750) (1G/2G) and the serum levels of matrix metalloproteinase 1 (MMP-1) with LD and its subtypes in people living with HIV on ART. This is a cross-secional study. LD was self-reported. The determination of the MMP1 rs1799750 gene polymorphism was performed by real-time PCR, and the serum concentrations of MMP-1 were quantified by the enzyme-linked immunosorbent assay (ELISA) method. Of 404 participants, 204 (51%) were diagnosed with LD, of whom 89 (43%) had mixed lipodystrophy (ML), 72 (35%) had lipohypertrophy (LH), and 43 (22%) had lipoatrophy (LA). There was an association between the genotypes 1G/1G+1G/2G and higher serum levels of MMP-1 (p = .025). There was no association of MMP1 (1G/2G) with LD. Other factors associated with LD were current CD4 ≤ 350 [odds ratio (OR) = 4.85, confidence interval (CI) = 1.78-47.99, p = .0033] and serum MMP-1 levels >6.81 (OR = 2.67, CI = 1.21-6.08, p = .0165). Factors associated with ML: current CD4 ≤ 350 (OR = 5.59, CI = 1.69-20.39, p = .006); with LH: number of antiretroviral regimens used: 2 (OR = 2.06, CI = 1.01-4.20, p = .0460) and 3+ (OR = 2.09, CI = 1.00-4.35, p = .0477), and current CD4 ≤ 350 (OR = 2.08, CI = 1.00-4.24, p = .0461); and with LA: current viral load >40 (OR = 2.52, CI = 1.03-5.91, p = .0372) and current use of zidovudine (OR = 2.97, CI = 1.32-6.54, p = .0074). Higher levels of MMP-1 were associated with genotypes 1G/2G+1G/1G and with LD. Other individual risk factors were independently associated with LD, and its subtypes, suggesting that the pathogenesis itself is differently manifested for each type of LD.

Abstract
The aim of this study was to perform a systematic review to identify data reported in the literature concerning the association of APOC3 (rs2854116), ESR2 (rs3020450), HFE (rs1799945), MMP1 (rs1799750) and PPARG (rs1801282) polymorphisms with lipodystrophy in people living with HIV (PLWHIV) on antirretroviral therapy. The research was conducted in six databases and the studies were selected in two steps. First, a search was undertaken in the following electronic databases: PubMed, Science Direct, Medline, World Wide Science, Directory of Open Access Journals, Scielo, Lilacs and Medcarib. The titles and abstracts of 24,859 articles were read to select those that match the elegibilty criteria. Five papers that addressed the association of HAART, lipodystrophy and polymorphisms were selected for the review. There was no association between the polymorphisms of the genes APOC3 and PPARG and lipodystrophy. Another study described an association between the variant allele (G) of HFE and protection concerning the development of lipoatrophy (0.02) when compared with the reference allele (C). On the other hand, the variant allele (T) of the ESR2 gene was associated with the development of lipoatrophy (p = 0.007) when compared with the reference allele (C). In addition, the genotype and the variant allele of the gene MMP1 (2G) were associated with lipodystrophy in PLWHIV on HAART (p = 0.0002 and p = 0.0008, respectively). Therefore, further studies with other populations, involving PLWHIV on HAART are necessary to better understand the role of genetic markers, which may be involved in a predisposition to lipodystrophy.

Abstract
INTRODUCTION Warfarin continues to be the most widely used anticoagulant in clinical practice around the world for the prevention of thromboembolic events in patients with atrial fibrillation (AF). The evaluation of the quality of anticoagulation control, estimated by time in therapeutic range (TTR), is accepted as a good method to evaluate the quality of anticoagulation. The variability of TTR can be explained by the presence of variants of the CYP2C9 and VKORC1 genes. METHODS This study examined the association between polymorphisms of the CYP2C9 and VKORC1 genes and control of oral anticoagulation, through TTR, in patients with AF. A cross-sectional study was conducted within a cohort follow-up. The study comprised of 317 patients with AF, using warfarin, who were followed up for one year. The genotyping of genes CYP2C9 (rs1057910), (rs1799853) and VKORC1 (rs923231) was performed by PCR in real time, using TaqMan probes. RESULTS Patients who had variant genotypes for the CYP2C9*3 gene (rs1057910) presented higher TTR (TTR 81-100%) when compared to when compared to the <45% and 46-60% TTR groups (p=0.005 and p=0.002, respectively). Regarding VKORC1 (rs923231), patients who had the variant genotype for the VKORC1 (rs923231) gene also presented a higher TTR (TTR 81-100%), when when compared to the <45% and 46-60% TTR groups (p=0.005 and p=0.004, respectively). In a multivariate model, VKORC1 (rs923231) remained associated for comparisons with the TTR groups (<45% vs 81-100% groups, p=0.01; and 46-60% vs 81-100% groups, p=0.01). CONCLUSION The genotypes of the CYP2C9*3 (AA) and VKORC1 -1639 (GG) genes were associated with the worst quality of anticoagulation control (TTR) in patients with AF using warfarin in the northeast of Brazil.

Abstract
INTRODUCTION Alcoholic Cardiomyopathy (ACM) is a disease with a difficult diagnosis. The real mechanisms related to its pathophysiology are not fully understood. OBJECTIVE The aims of this study were to investigate whether miR-133b and miR-138 could be associated with ACM. METHODS Forty-four patients were included comprising 24 with ACM and 20 with cardiomyopathies of different etiologies (control group). Real-time PCR was performed to verify the relative expression among the studied groups. In the statistical analysis, the quantitative variables t-student Mann- Whitney and correlation of Pearson tests were carried out, while the qualitative variable comprised the chi-square test, with p<0.05 being considered statistically significant. RESULTS There was no association between clinical and sociodemographic characteristics of the groups. The patients with ACM presented downregulation of miR-133b in comparison with control patients (p=0.004). On the other hand, for the miR-138, there was no association when the ACM group was compared with the control group. The presence of miR-133b among cases and controls was not correlated with any of the echocardiographic parameters. However, the increase in the expression of miR-138 was correlated with an increase in the ejection fraction (r=0.28, p=0.01) and the diameter of the left atrium (r=0.23, p=0.04) in patients with ACM. CONCLUSION The downregulation of miR-133b might be a marker for ACM and, in addition, miR- 138 could be used to correlate the increase in ejection fraction with and normalization of the diameter of the left atrium diameter in patients with this disease.

Abstract
INTRODUCTION Patients with sickle cell anemia (SCA) may present chronic hemolytic anemia, vaso-occlusion and respiratory tract infection (RTI) episodes. Galectin-3 (GAL-3) is a multifunctional protein involved in inflammation, apoptosis, adhesion and resistance to reactive oxygen species. Studies point to a dual role for GAL-3 as both a circulation damage-associated molecular pattern and a cell membrane associated pattern recognition receptor. OBJECTIVE To investigate associations between the SNPs of GAL-3 gene (LGALS3) and serum levels with RTI and vaso-occlusive crisis (VOC) in children with SCA. MATERIALS AND METHODS SNPs +191 and +292 in LGALS3 were studied using the TaqMan real-time PCR system; GAL-3 serum levels were measured by ELISA. The study included 79 children with SCA ranging from 2 to 12 years old. RESULTS GAL-3 serum levels were associated with LGALS3 +191 and +292 genotypes (p <0.0001; p = 0.0169, respectively). LGALS3 +191, AA genotype was associated with low and CC with higher levels of GAL-3. For LGALS3 +292, the CC genotype was associated with lower GAL-3 and AA with higher levels. Patients with Frequency of RTI (FRTI) ≥1 presented higher frequency of +191AA (p = 0.0263) and +292AC/CC genotypes (p = 0.0320). SNP +292 was associated with Frequency of VOC (FVOC) (p = 0.0347), whereas no association was shown with SNP +191 and FVOC. However, CA/AC and AA/CC genotypes with lower GAL-3 levels showed a higher frequency in patients with FRTI ≥1 (p = 0.0170; p = 0.0138, respectively). Also, patients with FVOC ≥1 presented association with CA/AC (p = 0.0228). LGALS3 +191 and +292 combined genotypes related to low (p = 0.0263) and intermediate expression (p = 0.0245) were associated with FRTI ≥1. Lower GAL-3 serum levels were associated with FRTI ≥1 (p = 0.0426) and FVOC ≥1 (p = 0.0012). CONCLUSION Variation of GAL-3 serum levels related to SNPs at +191 and +292 may constitute a susceptibility factor for RTI and VOC frequency.
