Abstract Genetic, epigenetic and environmental factors play an important role in the genesis of Type 2 Diabetes Mellitus (T2D). In the genetic context, one of the strategies used to investigate possible associations with diabetes is the search for Single Nucleotide Polymorphisms (SNPs), involving the comparison of alelle frequencies, the phenotypic variations and other relevant factors, such as environmental influences and lifestyle choices, Thus, the aim of this study was to find the relationship of risk variants for T2D in SNPs (rs4994) in the ADRB3 gene; (rs1799854) in the ABCC8 gene; (rs7901695 and rs12255372) in the TCF7L2 gene; and (rs8050136) in the FTO gene in a sample of the population of the municipality of Santarém (PA), Brazilian Amazon, in the northern region of Brazil. ABCC8 (rs1799854 C>T) showed a statistically significant association with T2D. Each chosen gene and SNP has been previously implicated in T2D risk according to existing scientific literature, owing to their roles in glucose regulation and body fat. Genetic TD .

Abstract The heterogeneous and vulnerable nature of the unhoused population reveal the complexity of living on the street and call for the State to play a fundamental role in the provision of health and social care policies. The scope of this study was to evaluate the intersectorality between health policies, social protection and organized civil society actions for the unhoused population in Brazil, based on an integrative literature review. To achieve this, a search was conducted in the SciELO, LILACS and PubMed databases, from which ten articles published between 2004-2021, all of a qualitative nature, were selected. From the analysis of the chosen articles, the evidence of intersectorality between the policies for the unhoused population was observed, mainly described as a point of intersection between the services offered. However, interventions are still poorly explored and systematized. It is recommended that quantitative studies aimed at the evaluation of intersectoral public policies be developed to allow the assessment of the impact of intersectorality between health services, social assistance and organized civil society on the quality of life of the unhoused population.

Malaria is nowadays one of the most serious health concerns in a global scale and, although there is an evident increase in research studies in this area, pointed by the vast number of hits and leads, it still appears as a recurrent topic every year due to the drug resistance shown by the parasite exposing the urgent need to develop new antimalarial medications. In this work, 38 molecules were synthesized via copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC) or “click” chemistry, following different routes to produce 2 different organic azides, obtained from a 4,7 dicholoquinoline, reacted with 19 different commercially available terminal alkynes. All those new compounds were evaluated for their in vitro activity against the chloroquine resistant malaria parasite Plasmodium falciparum (W2). The cytotoxicity evaluation was accomplished using Hep G2 cells and SI index was calculated for every molecule. Some of the quinoline derivatives have shown high antimalarial activity, with IC50 values in the range of 1.72-8.66 µM, low cytotoxicity, with CC50>1000 µM and selectivity index (SI) in the range of 20-100, with some compounds showing SI>800. Therefore, the quinolinotriazole hybrids could be considered a very important step on the development of new antimalarial drugs.

ABSTRACT The aim of this study was to develop and evaluate the antioxidant characteristics and sensory acceptance of Greek yogurt with added whole sorghum flours (WSF) from genotypes BRS305 (tannin) and BR501 (tannin-free). Five formulations were elaborated: 1) Control (without WSF); 2) 2% BR501; 3) 4% BR501; 4) 2% BRS305 and 5) 4% BRS305 and evaluated for antioxidant capacity, total anthocyanins, total phenols, condensed tannins, sensory acceptance and purchase intention. The 4% BRS305 formulation presented higher antioxidant properties, but lower sensory acceptance. No significant difference was observed for: color, flavor and overall acceptability between the control and 2% BR501; nor for texture and overall acceptability between the control and 4% BR501. Principal component analysis explained that all variables associated with antioxidant properties were positively correlated with the first major component (PC1: 82.7%). The 2% and 4% BR501 formulations were more highly correlated with PC1 (92.7%), as well as the control in relation to sensorial characteristics. The addition of WSF BRS305 improved the antioxidant properties of yogurts and the addition of WSF BR501 did not interfere with the sensory acceptance of the formulations. The similarity of the sensory acceptance of the yogurt containing WSF from the BR 501 genotype to the control, opens perspectives for the insertion of sorghum in human food, using dairy products as suitable matrices, adding potential functionality to this type of product.

RESUMEN El trabajo tuvo como propósito desarrollar y evaluar las características antioxidantes y la aceptación sensorial de yogurt griego con adición de harinas integrales de sorgo (HIS) de los genotipos BRS305 (con taninos) y BR501 (sin taninos). Cinco formulaciones fueron elaboradas: 1) Control (sin HIS); 2) 2% BR501; 3) 4% BR501; 4) 2% BRS305 y 5) 4% BRS305. Las formulaciones fueron evaluadas en función de su actividad antioxidante, antocianinas totales, fenólicos totales, taninos condensados, aceptación sensorial e intención de compra. La formulación 4% BRS305 presentó más propiedades antioxidantes, pero menor aceptación sensorial que las otras formulaciones. No se observó diferencia significativa entre el control y el 2% BR501 para el color, sabor e impresión global, ni tampoco para textura e impresión global en relación al 4% BR501. El análisis de componente principal ha explicado que todas las variables asociadas a las propiedades antioxidantes han sido positivamente correlacionadas con el primer componente principal (PC1: 82,7%). Las formulaciones 2% y 4% BR501 se han correlacionado más con el PC1 (92,7%), así como el control con las características sensoriales. La adición de HIS BRS305 ha mejorado las propiedades antioxidantes de los yogurts y la adición de HIS BR501 no ha interferido en la aceptación sensorial de las formulaciones. La similitud de la aceptación sensorial del yogurt que contiene el HIS del genotipo BR501 con el control, abre perspectivas para la inserción del sorgo en la alimentación humana, utilizando productos lácteos como matrices adecuadas, agregando funcionalidad potencial a este tipo de producto.

BACKGROUND Visceral Leishmaniasis (VL) is an infectious disease that is a significant cause of death among infants aged under 1 year and the elderly in Brazil. Serodiagnosis is a mainstay of VL elimination programs; however, it has significant limitations due to low accuracy. OBJECTIVE This study aimed to evaluate three recombinant Leishmania infantum proteins (rFc, rC9, and rA2) selected from previous proteomics and genomics analyses to develop enzyme-linked immunosorbent assay (ELISA) and immunochromatographic tests (ICT) for the serodiagnosis of human VL (HVL) and canine VL (CVL). METHODS A total of 186 human (70 L. infantum-infected symptomatic, 20 other disease-infected, and 96 healthy) and 185 canine (82 L. infantum-infected symptomatic, 27 L. infantum-infected asymptomatic, and 76 healthy) sera samples were used for antibody detection. FINDINGS Of the three proteins, rA2 (91.5% sensitivity and 87% specificity) and rC9 (95.7% sensitivity and 87.5% specificity) displayed the best performance in ELISA-HVL and ELISA-CVL, respectively. ICT-rA2 also displayed the best performance for HVL diagnosis (92.3% sensitivity and 88.0% specificity) and had high concordance with immunofluorescence antibody tests (IFAT), ELISA-rK39, IT-LEISH®, and ELISAEXT. ICT-rFc, ICT-rC9, and ICT-rA2 had sensitivities of 88.6%, 86.5%, and 87.0%, respectively, with specificity values of 84.0%, 92.0%, and 100%, respectively for CVL diagnosis. MAIN CONCLUSIONS The three antigens selected by us are promising candidates for VL diagnosis regardless of the test format, although the antigen combinations and test parameters may warrant further optimisation.

Introduction Muscle activity in the aquatic environment was investigated using electromyographic analyses. The physical properties of water and the resistance used may influence the response of the muscle during exercise. The objective of this study was to evaluate the electrical activity in water and on the floor during flexion and knee extension exercises with and without load and aimed at understanding the muscular response while performing resistance exercises in water. Methods The sample consisted of 14 volunteers between 18 and 35 years old who were subjected to active exercises involving knee flexion and extension with and without load on the floor and in water. Electromyography was performed during the movement. Results A significant increase was found in the electrical activity of the rectus femoris muscle during exercises on the floor. The biceps femoris muscle showed increased electromyographic activity when resistance was used. A significant increase was found in the electrical activity of the rectus femoris muscle compared with exercises with and without load and the moment of rest in immersion. The electrical activity of the rectus and biceps femoris muscles was reduced in exercises with load and without load in a therapy pool compared with on the floor. Conclusion There was a reduction of the electromyographic activity in the aquatic environment compared with that on the ground, which could be attributed to the effects from hot water. Therefore, it is believed that resistance exercises can be performed early in a therapy pool, which will facilitate the prevention and treatment of musculoskeletal disorders.

OBJETIVO: O objetivo desse estudo foi analisar as mundanças na quantidade de transfusão necessária com uso do Intraoperative red blood cell salvage (Cell saver), em pacientes submetidos a transplante ortotópico de fígado, doador cadáver. MÉTODOS: Foram avaliados dados de 41 pacientes submetidos a transplante de fígado. O sangramento foi calculado de acordo com débito do aspirador, compressas e captação do Cell saver. A reposição necessária foi avaliada de acordo com a quantidade de transfusão heteróloga e autóloga. Para análise dos dados os pacientes foram dividos em dois grupos: com e sem uso de Cell saver. RESULTADOS: A mediana de idade foi 50 anos e principal indicação de transplante foi cirrose hepática com 35 casos (85,3%). A mediana de sangramento durante o procedimento cirúrgico 8362 + 3994 ml (com cell saver) e 10824 + 7002 ml (sem cell saver) e a mediana de transfusão de concentrado de hemácias heterólogo, durante o período de internação hospitalar 9,6 + 8 unidades (com cell saver) compar 22,3 + 21 unidades (sem cell saver). CONCLUSÃO: Uso de Cell Saver tem um potential para reduzir a quantidade de transfusão heteróloga, dimuindo o risco de transmissão de doenças.

PURPOSE: The aim of this study was to analyse the changes in transfusion requirements, in patients submitted to orthotopic liver transpantation from cadaveric donors, with the use of intraoperative red blood cell salvage (Cell Saver). METHODS: Data from 41 transplants were analysed. Intraoperative blood loss was calculated from the cell salvage, suction and the swabs. The autologous and heterologous transfusions were recorded The red blood salvage was performed using the Cell Saver 5 System (Haemonetics).. For analysis the patients were divided in two groups: one that used the Cell Saver and another that didn't. RESULTS: The median age of the patients was 50 years and the main indication for liver transplantation was cirrhosis (35 cases - 85.3%). The median blood loss was 8362 + 3994 ml (with the Cell Saver) and 10824 + 7002 ml (without the Cell Saver) and the median transfusion of heterologous packed red blood cells was 9,6 + 8 units (with the Cell Saver) compared to 22,3 + 21 units (without the Cell Saver). CONCLUSIONS: The Cells Saver has the potential to reduce the need for heterologous blood transfusion reducing the risks of transmissible diseases.

The distribution of genetic polymorphisms of chemokine receptors CCR5-delta32, CCR2-64I and chemokine (SDF1-3’A) mutations were studied in 110 Human Immunodeficiency Virus type 1 (HIV-1) seropositive individuals (seropositive group) and 139 seronegative individuals (seronegative group) from the population of the northern Brazilian city of Belém which is the capital of the state of Pará in the Brazilian Amazon. The CCR5-delta32 mutation was found in the two groups at similar frequencies, i.e. 2.2% for the seronegative group and 2.7% for the seropositive group. The frequencies of the SDF1-3’A mutation were 21.0% for the seronegative group and 15.4% for the seropositive group, and the CCR2-64I allele was found at frequencies of 12.5% for the seronegative group and 5.4% for the seropositive group. Genotype distributions were consistent with Hardy-Weinberg expectations in both groups, suggesting that none of the three mutations has a detectable selective effect. Difference in the allelic and genotypic frequencies was statistically significant for the CCR2 locus, the frequency in the seronegative group being twice that found in the seropositive group. This finding may indicate a protective effect of the CCR2-64I mutation in relation to HIV transmission. However, considering that the CCR2-64I mutation has been more strongly associated with a decreased risk for progression for AIDS than to the resistance to the HIV infection, this could reflect an aspect of population structure or a Type I error.

Paciente sadio em que, ao exame de rotina, foi detectado nódulo pulmonar esquistossomótico com verme adulto, 25 anos após o tratamento específico com oxamniquine® e distante da região endêmica. O nódulo simulava clinicamente neoplasia.

OBJETIVO: Mostrar a eficácia do método para evitar biópsias excisionais, verificar suas dificuldades técnicas, definir entre seguimento e biópsia excisional nos nódulos categoria IV do BI-RADS™ e agilizar o procedimento cirúrgico nos casos de nódulos altamente suspeitos de malignidade (categoria V). MATERIAIS E MÉTODOS: As pacientes foram submetidas a exame clínico de rotina, mamografia e ultra-som. A "core" foi feita com pistola automática e agulha número 14, e foram colhidas de quatro a oito amostras. RESULTADOS: Das 100 lesões estudadas, 47 foram submetidas à cirurgia, além da "core", e diagnosticaram-se 34 carcinomas (34,0%). Das 23 lesões classificadas como categoria III, identificou-se apenas um carcinoma (4,34%); das 43 classificadas como categoria IV, sete (16,28%); e das 34 classificadas como categoria V, 26 (76,47%). Evitou-se a biópsia excisional em 53 casos (53,0%). Identificou-se dificuldade no método da "core" em sete casos (7,0%), devido a material insuficiente, risco para malignidade envolvendo lesões esclerosantes complexas e discordância entre imagem e histologia. As 33 lesões com resultados de malignidade à punção biópsia por agulha grossa foram confirmadas após a biópsia cirúrgica. Em um caso o diagnóstico pela "core" foi de hiperplasia ductal atípica e após a biópsia cirúrgica da peça diagnosticou-se carcinoma, correspondendo a um resultado falso-negativo. Não houve nenhum resultado falso-positivo.

OBJECTIVE: To demonstrate the efficacy of core-needle biopsy to avoid unnecessary surgery; to assess the technical difficulties of this method; to establish decision criteria for clinical follow-up or surgery in patients with lesions classified as suspicious for malignancy (BI-RADS IV); to expedite surgery in patients with lesions classified as highly suspicious for malignancy (BI-RADS V). MATERIALS AND METHODS: The patients were submitted to clinical examination, mammography and ultrasound. Core-needle biopsy was done using a 14-gauge needle, and 4-8 cores per lesion were obtained. RESULTS: A hundred lesions were studied, 47 of them underwent surgery and biopsy, and 34 cancers were diagnosed. In 23 lesions classified as probably benign (III) only one case of cancer was diagnosed (4.34%). In 43 lesions classified as IV, seven (16.28%) cancers were found whereas in 34 lesions classified as V, 26 (76.47%) cases of cancer were identified. It was possible to avoid surgery in 53 cases (53%). Difficulties in core-needle biopsy occurred in seven cases including insufficient material, risk of malignancy due to sclerosing lesions and lack of correlation between imaging and core-needle biopsy results. All the core biopsy diagnoses of malignancy were confirmed by surgery. There was one false negative result when the core biopsy specimen examination showed atypical hyperplasia while surgery specimen analysis revealed a carcinoma. There were no false positive cases.
