title: The use of sugar beet pulp in pig diet to control skatole analysed by HPLC quantification method

description: ABSTRACT This study aimed to determine the efficacy of a finishing diet added with sugar beet pulp to reduce backfat skatole of entire male pigs, using the optimised high-performance liquid chromatographic (HPLC) method. The study comprised 72 males Pietrain (Large White × Landrace), divided into two groups of 36 animals each. Pigs in group A (treatment) were fed a supplemented formula (addition of 10 % beet pulp). while animals in group B (control) received a commercial feed, both for a period of 14 days before slaughter. The isocratic HPLC method achieved the chromatographic separation of indolic compounds in approximately 3 min. Skatole was significantly lower ( p = 0.002) in group A, showing that beet root supplementation reduced skatole levels in pig fat. In addition, the optimised HPLC method was reliable, less time-consuming, and showed a resolution suitable for small amounts of skatole.

title: Verbenaceae in Itacolomi State Park, Minas Gerais, Brazil: richness, geographical distribution, and a new synonym for Stachytarpheta commutata

description: Abstract Verbenaceae includes 32 genera and approximately 800 species distributed mainly in the Neotropical region, especially diversified in Brazil, where the campo rupestre stands out as an important vegetation type for the family. The Itacolomi State Park (ISP) is located in the southeast of the Quadrilátero Ferrífero, Minas Gerais state (MG), Brazil. Vegetation at the Park is composed of campo rupestre and forest remnants among degraded areas. The present research provides a floristic treatment of Verbenaceae in this protected area. Data were obtained from fieldwork and herbarium study. A total of 13 species were recorded: Glandularia phlogiflora, Lantana camara, Lantan fucata, Lantana tiliaefolia, Lantana trifolia, Lippia brasiliensis, Lippia hermannioides, Lippia origanoides, Petrea volubilis, Stachytarpheta cayennensis, Stachytarpheta commutata, Verbena litoralis and Verbena rigida. Among them, six are new records for the ISP. Stachytarpheta glabra, endemic to MG, was found in an area of canga very close to the boundaries of the Park. Additionally, S. viscidula, whose type locality is close to the Park, is proposed as a new synonym for S. commutata, whose type specimen comes from the Park. We provide an identification key, descriptions, photographs and comments on taxonomy, ecology and distribution for each species.

title: General Approach to Acute Myocardial Infarction with Nonobstructive Coronary Arteries (MINOCA): A Systematic Review

description: Abstract Background Acute myocardial infarction (AMI) without obstructive coronary arteries (MINOCA) is a medical condition of great relevance, with clinical characteristics of AMI, but without evidence of coronary artery obstruction. The mechanism involved in the pathophysiology of the disease and its possible etiologies are important objects of study due to their impact on the morbidity and mortality of affected patients. Objectives The aim of this study was to systematically review MINOCA and its characteristics, with emphasis on the clinical profile of patients, etiology, pathophysiology, diagnosis, and treatment of the syndrome. Methods Relevant articles related to MINOCA were analyzed in the PubMed and LILACS databases. In the initial search stage, 619 eligible articles were obtained, with final inclusion criteria being: original systematic reviews with clinical, epidemiological, diagnostic, or treatment data on MINOCA, published in Portuguese or English, with an abstract, and a publication date limit of September 2020. Results A total of 10 articles classified as systematic reviews that considered clinical data on MINOCA were included in this review. Conclusion After analyzing various literature, the present study provided a tool to better understand MINOCA, not only regarding its casuistry but also in grouping parameters and information that contribute to a healthy approach to this clinical situation. It was possible to identify and better outline the clinical profile of patients who presented this condition and the use of appropriate tools for correct diagnosis and ideal treatment.

title: Development and validation of an analytical method by HPLC-DAD for determination of caffeine in products based on guarana extracts (Paullinia cupana)

description: Abstract Guarana (Paullinia cupana) is a native plant from the Amazon whose seeds contain a high concentration of caffeine. Aqueous extract of guarana is widely used in the world. In this study, the objective was to develop and validate a High-Performance Liquid Chromatography method for the determination of caffeine in extracts and commercial beverages based on guarana. A sensitive, simple, and viable high performance liquid chromatographic method without the need of an analyte extraction procedure was developed and validated according to Brazilian and international requirements. The method presented high performance, fulfilling Brazilian and international requirements, in addition to allowing product compliance tests. Results confirmed high selectivity and linearity (&gt;0.999) between 5 to 135 ug/mL, with no significant matrix effect. Detection and quantification limits were 0.02 µg/mL and 2 µg/mL, respectively. Precision was less than 4 %, and accuracy varied from 99.9-120 %. Applicability of the method was demonstrated by conducting a limited evaluation in products containing caffeine. Commercial extracts showed quite different caffeine levels, while carbonated drinks follow Brazilian and American recommendations. Our results indicate that the developed method can be used to evaluate the quality of the guarana extract and of products containing caffeine.

title: Motor and cognitive outcomes of neonates with low birth weight in Brazil: a systematic review and meta-analysis

description: Abstract Background Data on the outcomes of preterm newborns in South American countries are scarce. Given the great effect of low birth weight (LBW) and/or prematurity on children’s neurodevelopment, it is extremely necessary to conduct studies on these phenomena in greater depth in more heterogeneous populations such as those ones from countries with limited resources. Methods We conducted a comprehensive literature search on databases including PubMed, the Cochrane Library, and Web of Science for articles published in Portuguese and English up to March 2021 involving children born and evaluated in Brazil. The analysis of the risk of bias was adapted from the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement and used to evaluate the methodology of the included studies. Results From the eligible trials, 25 articles were selected for qualitative synthesis, and 5 of those, for quantitative synthesis (meta-analysis). The meta-analyses showed that children born with LBW presented lower scores on motor development when compared with controls (standardized mean difference: –1.15; 95% confidence interval [95%CI]: –1.56-–0.73]; I2: 80%) and also scored lower in terms of cognitive development (standardized mean difference: –0.71; 95% CI: –0.99––0.44; I2: 67%). Conclusion The results of the present study reinforce that impaired motor and cognitive functions can be a significant long-term outcome of LBW. The lower the gestational age at delivery, the higher the risk of impairment in those domains. The study protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database under number CRD42019112403.

title: Why all the field technicians of the National Chagas Program in Argentina are men?

description: Abstract Chagas is a disease caused by the parasite Trypanosoma cruzi and a socio-environmental health problem present throughout the world. One of the routes of transmission of this parasite is through contact with feces of infected kissing bugs. In Argentina there are vector control programs that are responsible for preventing this route of transmission. Specifically, those who are in charge of this work are the field technicians, who are practically all men. Through a qualitative and interpretive approach that included interviews, documentary analysis and observation, we investigated why women do not participate in this occupational area in the National Program of Chagas. Most of the people interviewed justified the lack of women based on gender stereotypes. Another group indicated that it is due to the possible damage that insecticides would generate in women. We found that there is occupational segregation by gender towards women and other sex-gender identities, since there are no official recommendations or regulations which forbids women to perform in this type of job. We believe that it is necessary for the work teams to be diverse in terms of gender, since it would improve vector control interventions and strategies in the different territories.

title: Optimization of automated preparation of long oval-shaped root canals using supplementary instrumentation

description: Abstract This study compared the preparation of long oval-shaped root canals using WaveOne Gold and XP-endo Shaper systems, both supplemented or not with manual instrumentation. Twenty-four long oval-shaped canals of mandibular incisors were distributed into two groups according to the instrumentation: WaveOne Gold Primary or XP-endo Shaper systems. All root canals were manually instrumented with a size 25 K-file after automated preparation. The specimens were scanned by using a micro-CT device (17.42 µm) before and after automated preparation and manual instrumentation. The increased surface of the root canal and the percentage of untouched areas were assessed. Both WaveOne Gold and XP-endo Shaper systems increased the root canal surface and had similar untouched areas (p&gt;0.05). Supplementary instrumentation increased the surface of the root canal and decreased the untouched walls (p&lt;0.05). WaveOne Gold and XP-endo Shaper systems provided a similar preparation of long oval-shaped canals and manual instrumentation improved their preparation.

title: Characterization of whitening toothpastes and their effect on the physical properties of bulk-fill composites

description: Abstract Objective To characterize activated charcoal and 2% hydrogen peroxide-based toothpastes and investigate their effects on roughness, color change, and gloss of bulk-fill composite resin. Methodology Composite resin specimens (Aura Bulk Fill, SDI) were subjected to 5,000 brushing cycles with regular toothpaste (Colgate Total 12, [RT]), activated charcoal toothpaste (Bianco Dental Carbon, [AC]), or hydrogen peroxide-containing toothpaste (Colgate Luminous White Advanced, [HP]), with or without coffee exposure. The pH, particle characterization by scanning electron microscopy (SEM), and weight% of solid particles in the toothpaste were assessed. Roughness (Ra) was evaluated using a surface profile-measuring device, color change (∆Eab/∆E00) by reflectance spectrophotometer, and gloss unit (GU) by glossmeter. Kruskal–Wallis, Dunn, Friedman, and Nemenyi tests were used, and the correlation coefficient test was performed between Ra and GU (α=0.05). Results RT presented a higher Ra after brushing and did not change after staining with coffee; moreover, the ∆Eab/∆E00 values were higher for RT than HP. Regarding gloss, AC and HP obtained higher values compared to RT. A significant negative correlation between gloss and Ra was found for RT exposed to coffee. All toothpastes had a neutral pH; however, RT had the largest percentage of solids by weight. SEM images showed particles of many sizes: irregular shape (RT), more regular particles (AC), and spherical clusters (HP). Although surface roughness, color change, and gloss may compromise the longevity of restorations, the whitening toothpastes tested did not promote more morphology changes than regular toothpastes.
