ABSTRACT: The study evaluated the efficacy and soybean spectral responses to fifteen foliar fungicide mixtures labeled to control Asian soybean rust. Canopy level reflectance was measured using a multispectral camera onboard a multirotor drone before and two hours after each spray. The third application of fungicides improved control of soybean rust and increased yield. Nevertheless, up to three consecutive foliar fungicides applications did not affect the reflectance of soybean plants at visible and infrared wavelengths. Thus, drones can be a viable strategy for data acquisition regardless of the application of the fungicides.

ABSTRACT: This research evaluated the biomass productivity and nutritional value of the haylage and hay from intercropping between Tamani grass and different legume species. For the productive characteristics of the different intercrops, we adopted a randomized block design, for evaluation of the combination of intercropping and conservation technic we used 5 x 2 factorial scheme (five intercrops and two types of conservation techniques). The treatments were Tamani grass as monoculture, and the intercrops of Tamani grass with crotalaria, soybean, cowpea, or pigeon pea. The conservation techniques were haylage (520 g/kg of DM) and hay (870 g/kg of DM). Plants were sown in alternate rows, with 45 cm of spacing between the rows. The parameters evaluated were grass and legume biomass production, canopy height, and haylage and hay chemical composition, and in vitro dry matter digestibility (ivDMD). There were no differences in the total biomass production between the intercrops and TA grass monoculture. The treatments intercropped with cowpea and soybean had the highest legume participation in the mixture, promoting an increase in crude protein and ivDMD content of haylage and hay. Haylage and hay had the same chemical composition, although haylage had higher ivDMD than hay. We concluded that intercropping Tamani grass with soybeans or cowpea maintained total biomass productivity and improved the nutritional value of haylage and hay.

Published: April 2022

RESUMO A formação de professoras para a educação das futuras gerações se traduz em grande desafio, principalmente quando se acredita que junto do compartilhar de conteúdos científicos, curriculares, entende-se como partícipes dessa relação de aprendizado o compartir de conteúdos morais, sociais, éticos, estéticos etc. Daí, pensar em uma educação que se estabeleça em diferentes bases pode se tornar promissor, haja vista a possibilidade de se somar formação profissional e formação pessoal. Nessa perspectiva, utilizando os construtos teóricos eliasianos e a abordagem (auto)biográfica em suas interfaces com o campo educativo, o artigo traz à baila o inventário de um arquivo pessoal docente com foco em memoriais de infância (auto)biográficos elaborados por acadêmicas do curso de Pedagogia da Faculdade de Educação (FAED) da Universidade Federal da Grande Dourados (UFGD), localizada em Dourados, estado de Mato Grosso do Sul (MS). O objetivo foi examinar a formação inicial de professoras que, em perspectiva, trabalharão com a educação das crianças. Analisaram-se diferentes figurações que compuseram esses processos, bem como teias de interpendência presentes nas trajetórias da professora e das acadêmicas, apreendendo que a (re)significação do vivido, ato reflexivo entendido como sendo de autoconhecimento do indivíduo, pode viabilizar o (re)constituir-se, propiciando novos fazeres para o cenário educativo.

Published: April 2022

Abstract Hepatitis C virus infection (HCV) is the foremost reason of progressive hepatic fibrosis and cirrhosis, with an elevated risk of hepatocellular carcinoma (HCC) development. Medicinal plants have been used for human health benefits for several years, but their therapeutic potential needs to be explored. The main objective of this study was to figure out the in vitro antiviral and anticancer characteristics of total crude protein of Iberis gibraltarica against HCV and HCC. Total crude protein of Iberis gibraltarica was isolated and quantified. The level of cytotoxicity was measured against the HepG2 cell line and it shows no significant cytotoxicity at the concentration of 504µg/ml. The anti-HCV effect was determined by absolute quantification via real time RT-PCR method and viral titer was reduced up to 66% in a dose dependent manner against the total protein of Iberis gibraltarica. The anticancer potential of Iberis gibraltarica was also examined through mRNA expression studies of AFP and GPC3 genes against the total protein of Iberis gibraltarica-treated HepG2 cells. The results show up to 90% of the down-regulation expression of AFP and GPC3. The obtained results indicate the therapeutic potential of total protein of Iberis gibraltarica against HCV and hepatocellular carcinoma in vitro.

Abstract The aim of this article was to analyze the relationship between the informational content of the key audit matters (KAMs) reported in the Independent Audit Report (IAR) and financial analysts’ forecasts for the companies listed on the B3 S.A. - Brasil, Bolsa, Balcão (B3). The research that has investigated the relevance of KAMs has not analyzed the incremental information about the audited firm, from the independent auditor’s viewpoint, that can affect financial analysts’ forecasts. The findings of this research reveal that the KAMs reported present relevant informational content about the audited firm for financial analysts, thus improving the quality of their forecasts. In addition, it was observed in the quantile analysis that the KAMs contribute to the fine tuning of analysts’ forecasts. The debate on the auditor-analyst relationship is also widened, specifically regarding the utility of KAMs for financial analysts, in terms of them considering using this information in their projections for the analyzed companies, thus reinforcing the search for their improvement by the regulator. The analysis was conducted based on generalized least squares (GLS) and quantile regressions covering 137 non-financial companies, using data from (quarterly and annual) analysts’ forecasts available from Thomson Reuters Eikon® and financial information from Economatica®. In general, the quantity and content of the items reported as KAMs were revealed to be significant in relation to the analysts’ earnings per share forecasts and to their forecasting error, revealing a reduction in asymmetry. Thus, the higher the informational value of the KAMs, the better the quality of that information is, contributing to forming an earnings forecast consensus and minimizing the error in the financial analysts’ estimates. In addition, it was observed that the disclosure of KAMs has no immediate reflection in the earnings forecast in the quarter following their disclosure, with their informational content being diluted over the following financial period, impacting the annual earnings forecast.

Published: April 2022

RESUMO O gorgulho-do-milho, Sitophilus zeamais é considerado uma das principais pragas de grãos armazenados. Visando à busca de um método alternativo de controle dessa praga, avaliou-se, em laboratório, o potencial inseticida dos pós de frutos e da planta inteira (com frutos) de Chenopodium ambrosioides. Os insetos utilizados nos ensaios foram obtidos de criação mantida em grãos de trigo. Avaliou-se o efeito inseticida dos pós sobre a fase imatura e adultos do inseto, utilizando-se caixas plásticas contendo 20 g de trigo em seu interior, e liberados 20 adultos de S. zeamais para que realizassem a oviposição. Após 3 dias, os insetos foram retirados, e aos 15 e 21 dias após a infestação foram adicionados 0,25 g dos pós de C. ambrosioides. As avaliações foram realizadas no período de 25 a 60 dias a contar da infestação inicial. Para avaliação do poder residual, foram utilizadas caixas plásticas contendo 20 g de trigo em seu interior, e colocados 0,25 g dos pós de C. ambrosioides, separados e em contato com os grãos. Posteriormente, foram liberados 20 adultos de S. zeamais, em diferentes períodos: no momento da instalação do ensaio (0 dia), e após 5, 10 e 20 dias. As avaliações foram realizadas 5 dias após a infestação, contandose o número de insetos mortos. Concluiu-se que pós de frutos e da planta inteira (com frutos), aplicados após 15 dias da infestação inicial, possuem efeito inseticida sobre a fase imatura de S. zeamais e que pós de frutos apresentam efeito inseticida residual contra adultos do inseto pelo período máximo de 5 dias.

RESUMO O meloeiro é uma das principais culturas de exportação do Nordeste, que tem como pragachave, a mosca-branca Bemisia tabaci biótipo B. Para controlá-la têm sido utilizados, freqüentemente, inseticidas de largo espectro e muitas vezes não registrados, promovendo o desenvolvimento de populações resistentes da praga. Estudou-se a eficiência de produtos naturais sob condições de casa de vegetação e de campo. O delineamento foi inteiramente casualizado, representado por 7 tratamentos: T1-Testemunha absoluta, T2-extrato pirolenhoso (Pironat), T3-extrato de timbó (Rotenat), T4-Beauveria bassiana (Bovenat), T5-Metarhizium anisospliae (Metanat), T6-óleo de neem (Natuneem) e T7-imidacloprid (Confidor 700 GrDA), distribuídos em 4 repetições. Avaliou-se a média de ninfas em casa de vegetação e a média de adultos e ninfas nas folhas do meloeiro em campo. Em casa de vegetação, observou-se que a maior eficiência no controle de ninfas de B. tabaci biótipo B foi obtida quando aplicaram-se o óleo de neem (66,49%) e o extrato pirolenhoso (67,35%). Já em condições de campo, verificou-se que o óleo de neem foi o inseticida vegetal mais eficiente para o controle de adultos e ninfas da praga. Os produtos à base de fungos entomopatogênicos foram mais eficientes no controle de ninfas, sendo o Metarhizium anisopliae mais eficiente do que Beauveria bassiana. O extrato de timbó foi mais eficiente no controle de adultos de Bemisia tabaci biótipo B no início de cultivo do meloeiro e para ninfas, no final do ciclo, enquanto que o extrato pirolenhoso apresentou aumento na eficiência de controle de ninfas ao longo do desenvolvimento da planta, com uma redução no controle de adultos no final do ciclo da cultura.

RESUMO Avaliou-se a etiologia de bactérias aeróbicas e fúngica e a sensibilidade microbiana in vitro de agentes bacterianos, de 207 éguas com endometrite. Obteve-se o isolamento microbiano em 75 (36,5%) amostras de secreção uterina. Isolou-se com maior freqüência Streptococcus beta-hemolítico (32,0%), Escherichia coli (17,3%) e Corynebacterium spp. (12,0%). Dentre os agentes de origem fúngica identificou-se Candida albicans (4,0%) e Geotrichum candidum(1,3%). No teste in vitro de sensibilidade microbiana, a norfloxacina (77,0%), a ampicilina (72,3%) e a gentamicina (63,5%) foram os antimicrobianos mais efetivos. Estreptomicina (68,75%), sulfadiazina/trimetoprim (50,5%) e penicilina G (48,7%) apresentaram os maiores índices de resistência frente aos agentes. O presente estudo ratifica a complexidade etiológica na gênese de infecções uterinas na espécie eqüina, e a importância do perfil in vitro de sensibilidade microbiana, como subsídio para procedimentos terapêuticos.

Abstract The objective of this work was to evaluate the potential of the essential oils of the LGRA-106 and LGR A-108 Lip pia g racili s genot y pes for the control of diamondback moth (Plutella xylostella). The lethal concentrations (LCs) were estimated by two routes of action (residual and spraying), using oil concentrations ranging from 0.5 to 3.0% v v−1, diluted in Tween 80 (1.5%). To determine the effect of the LC to 50% (LC50) on the development of P. xylostella, two compounds of the L. gracilis genotypes, thymol, and carvacrol, were sprayed on the insects. The repellency of the LC50 was evaluated by residual action, in a free-choice behavioral bioassay. The LGRA-106 genotype showed a greater toxicity via residual action (LC50 = 8.82 mg mL−1), as well as a higher repellency index. LGRA-108 was more toxic via spraying (LC50= 9.64 mg mL−1). Larval development and viability were reduced in approximately 50% with LGRA-106 or thymol and up to 70% with LGRA-108 or carvacrol, which caused mortality from 1.70 to 1.97 days after spraying. The oils of the LGRA-106 and LGRA-108 genotypes of L. gracilis have insecticidal activity in the control of P. xylostella.

Abstract The objective of this work was to simultaneously select pre-commercial grain sorghum hybrids with high adaptability and yield stability, through mixed modeling, in 20 environments, during six years. The evaluated plant material consisted of 57 commercial grain sorghum hybrids. In all experiments, hybrids were arranged in a triple lattice design; some experiments used a 6x6 lattice, and others, a 5x5 lattice. Adaptability and stability parameters were obtained based on the prediction by harmonic mean of the relative performance of genotypic values (HMRPGV). The mixed models proved to be adequate to analyze the genotype x environment (GxE) interaction and the genotypic adaptability and stability studies on grain sorghum. The hybrids that stand out, considering all environments are 1G282, A9904, 50A50, A9902, and XB6022. The A9904 hybrid stands out in favorable environments, with a grain yield above average. Only 1G282 is among the five best hybrids for each group of environments, and it is the best grain sorghum hybrid for yield performance, adaptability, and stability. The predicted genotypic values based on genotypic means can be used in the environments with the same GxE interaction pattern because they are free of the GxE interaction.

ABSTRACT Objective: To compare the interobserver reliability of measurements of psoas morphology and lumbar lordosis in different positions and to standardize the performance of magnetic resonance imaging in the prone and lateral positions. Methods: This is a cross-sectional study carried out with asymptomatic volunteers of both sexes, aged over 18 years, with no known pathological changes in the lumbar region. Magnetic resonance imaging of the lumbar spine was performed in the supine, right lateral decubitus and prone positions, obtaining images in T2-weighted sequences in the sagittal and axial planes. The distances were measured from the psoas to the vertebral plateau and from the psoas to the lumbar plexus. The exams were assessed by two independent, blinded orthopedists. Results: There was excellent agreement between the measurements of vertebral size (ICC=0.92), low agreement for plexus distance (ICC=0.63) and high agreement for the anterior margin (ICC=0.84). Conclusion: There was good reproducibility of 2 of the 3 measures proposed, suggesting that the technique in the lateral and prone positions is capable of generating quality images.

Published: April 2022

ABSTRACT Objective: To analyze the pre- and postoperative spinopelvic parameters and global sagittal balance of patients with adolescent idiopathic scoliosis (AIS) divided into 3 groups (Group 1 – thoracic arthrodesis, Group 2 - thoracolumbar arthrodesis, and Group 3 – lumbar arthrodesis), observing differences in these two moments and whether the parameter values are maintained or not over a period of up to 2 years following surgery. Methods: We analyzed the radiographs from a single-center database of 99 patients who underwent arthrodesis with posterior instrumentation. Pelvic incidence, pelvic version, sacral slope, lumbar lordosis, thoracic kyphosis, and sagittal vertical axis values were measured in the pre- and postoperative radiographies of each patient. Results: The parameters of pelvic incidence, pelvic version, sacral slope, and sagittal vertical axis did not show statistically significant differences among the 3 groups. There was a difference in preoperative lumbar lordosis between the 3 groups (p = 0.049). Thoracic kyphosis showed differences both in the pre- (p = 0.015) and postoperative (p = 0.042) values, in addition to demonstrating a relationship of dependence between the pre- and postoperative values in the final statistical analysis. Conclusion: The evaluation of the parameters analyzed shows that the study groups have similar values of individual balance, with the exception of thoracic kyphosis and lumbar lordosis, which are measurements that depend on the surgical technique and compensatory mechanisms, but remained within normal ranges. These factors allow the surgeon to be attentive to both the coronal and sagittal planes when planning the correction in order to achieve the equilibrium of the trunk in addition to correction of the deformity.

ABSTRACT Introduction: Vertebral fracture is the main complication of osteoporosis and is common among the elderly. Conservative treatment is the first choice for osteoporotic vertebral compression fractures (OVCF) but for persistent painful cases, percutaneous vertebral cement augmentation techniques, such as vertebroplasty and kyphoplasty, are indicated. We performed a systematic review to compare clinical and radiological outcomes of both methods. Methods: A systematic review was performed according to the PRISMA and Cochrane Handbook for Systematic Reviews of Interventions. The PICO search strategy consisted of the following terms: Population- Patients with OVCFs; Intervention- Kyphoplasty; Control- Vertebroplasty; Outcomes- Pain, Cement Leakage, Vertebral Body Height, Adjacent level fractures, Oswestry (ODI) and SF36. Results: Seven articles were included in the qualitative analysis, selecting only randomized controlled trials. Four hundred and fifty patients were treated with vertebroplasty (VP) and 469 with kyphoplasty (KP). The leakage rate of the VP group was 63% versus 14% for the KP group. However, these results were without statistical significance. The Visual Analogue Scale (VAS), ODI and SF-36 outcomes were evaluated based on the 6-month and 1-year follow-up results, and we were unable to find any significant differences between treatments. For restoration of vertebral height, the values of the KP group were, on average, 0.71 cm higher than those of the VP group, with 95% CI. Conclusion: Based on this systematic review, kyphoplasty is superior to vertebroplasty for achieving gains in vertebral body height. As regards cement leakage and other clinical outcomes, neither method showed statistically significant superiority. Level of Evidence I; Systematic review.

ABSTRACT Introduction: Denosumab is a human monoclonal antibody that binds to the receptor activator of nuclear factor kB (RANKL), it is used in the treatment of Osteoporosis. The Giant Cell Tumor (GCT) and the Aneurysmal Bone Cyst (ABC) use the same RANKL, and for this reason this drug began to be used for its treatment. There is consensus on the use, dose-time and 12-month duration for Denosumab treatment of GCT. Not so for ABC. In unresectable, disabling or recurrent tumors, its use could be for life. The adverse events of the habitual use of the drug are known, but it is not known if these increase with time. The objective of the present work is to identify the possible adverse events of treatment with Denosumab for more than 12 months. Material and Method: Series of cases with a diagnosis of GCT or ABC in spine, treated with Denosumab for more than 12 months. Adverse events are: arthralgia, fatigue, spinal pain, pain in extremities, headache, hypokalaemia, hypocalcemia, osteonecrosis of the jaw, malignant transformation, pathological fractures. Results: Eight patients, 6 TCG and 2 ABC, with a mean age at diagnosis of 25,6 years; presenting a mean treatment of 4.18 years (range 1.7 - 8.7). Of 6 operated patients, 4 had recurrence (2 to 36 months after surgery). One patient had to suspend treatment due to necrosis of the jaw, another hypocalcemia, both returned to treatment when stabilized. Conclusions: A minor adverse event (hypocalcemia) and a major adverse event (jaw bone necrosis) were observed. Level of Evidence IV; Original.

Methods: A retrospective cohort study, with patients treated by percutaneous interlaminar or transforaminal endoscopic discectomy at the Spine Service of the ISCMPA, in southern Brazil. Data were collected from the patients’ electronic medical records by two independent physicians. The clinical outcomes of pain intensity and lumbar functionality were evaluated, respectively, using the visual analogue scale and the Oswestry Disability Index. Results: Thirty-six patients were included in the study, with a mean age of 50.8 ± 15.3 years, 19 (52.8%) of whom were males. As for the clinical outcomes for both transforaminal and interlaminar percutaneous endoscopic approaches, we observed a statistically significant reduction in pain intensity (mean difference of 3.5 points, p < 0.001) and a statistically significant improvement in functionality (mean difference of 33.2 points, p < 0.001) when we compared the pre- and 30-day postoperative periods, with no significant differences in terms of approaches. The type of technical approach also differed in relation to the patients’ age, the location, type, and migration of the herniated disc, and the patient’s time in the operating room. Conclusion: There was a similar effect on pain reduction and restoration of lumbar functions, 30 days after percutaneous endoscopic discectomy, in both technical approaches, with no significant differences between them.

ABSTRACT Introduction: Upper lumbar disc herniations (ULDH) are considered infrequent injuries (1-11%). They present, most often in older adults, with special clinical features that make diagnosis and therapeutic decision-making difficult. The prevalence, location, and management of these herniations and the medical history of our patients were analyzed. Methods: Sex, age, injury level, previous surgery, and patient treatment data from July 2018 to May 2021 were collected retrospectively. During this period, 179 patients underwent surgery, 33 of whom patients presented ULDH. Results: Thirty-three patients were included in the study (18 male and 15 female). Ages ranged from 39 to 85 years, with a predominance of elderly patients. The levels operated were L1-L2 in seven patients, L2-L3 in ten patients, L3-L4 in fourteen patients, and surgery in two levels (L2-L3, L3-L4) in two patients. In our practice, microdiscectomy is the preferred approach and was performed in all cases, with the addition of fusion in four of the 33 patients. Finally, a history of low lumbar disc herniation (LLDH) surgery was found in 16 patients. Conclusions: In our population, ULDHs are a rare entity with lower prevalence at the higher lumbar levels. They occur more frequently in elderly patients and clinical presentation can vary, which is a challenge for surgeons. In older adults, the development of lumbar kyphosis due to vertebral wedging is considered a risk factor for the development of ULDH. Surgical management by microdiscectomy is considered a technique with good results for this pathology. Level of Evidence III; Retrospective, longitudinal, descriptive, observational study.

ABSTRACT Objective: To report the results of our patients who underwent scoliosis correction surgery in relation to their quality of life. Introduction: Juvenile idiopathic scoliosis affects between 1 and 3% of the population during puberty. Treatment will be conservative in most cases. The goal of surgical treatment is to improve coronal and sagittal alignment. The SRS 22 questionnaire is a useful tool for assessing quality of life in these patients. Methods: A retrospective study of 22 patients submitted to corrective surgery for juvenile idiopathic scoliosis between October 2017 and January 2020 was conducted. All of them had curves greater than 45 degrees managed through instrumentation and arthrodesis. Post-surgical quality of life was assessed using the SRS 22 questionnaire. Results: The average age of our patients at the time of the intervention was 15.5 years with a predominance of female patients. The application of the SRS 22 questionnaire generated the following mean scores: pain 4.6, function 4.3, self-image 4.41, mental health 4.89, and satisfaction 5.0. Conclusions: The development of surgical techniques has allowed good results to be achieved in the treatment of scoliosis. The evaluation of our patients using the SRS 22 questionnaire reflects a good quality of life in the 5 parameters evaluated. The main limitations of this study were the small sample size and its retrospective nature. Level of Evidence III; Retrospective, longitudinal, descriptive, observational study.

A quantitative study on the synergistic effect between limestone powder and supplementary cementitious materials
Authors: Wang Dehui , Jia Huangfei
Published: April 2022

As an industrial solid waste from limestone quarrying, limestone powder (LP) is often used in cement-based materials to reduce cost and carbon dioxide emissions. It is well known that the synergistic effect between LP and alumina-rich supplementary cementitious materials (SCMs) influences the properties of cement-based materials. To study the synergistic effect quantitatively, the hydration heat, hydration products and porosity of cement pastes with different binders were investigated. Test results showed that the synergistic effect between LP and fly ash (FA) or slag (S) improved the hydration degree and increased the total hydration heat of the pastes. When FA or S were incorporated along with LP, the calcium carbonate consumption at 3 days increased from 2.0 wt% to 4 wt%; at 180 days it increased from 2.4 wt% to 9.3 wt% (with FA) and 11.8 wt% (with S). The incorporation of FA or S also increased the diffraction peak of carboaluminate, indicating more carboaluminate was formed. The synergistic effect between LP and SCMs refined the pore structure and reduced the porosity of the cement pastes. The synergistic effect between LP and FA or S increased the density of the cement pastes by 1.04% or 1.41%, respectively, and correspondingly improved the compressive strength of the pastes.
Surficial mass movements on cut slopes of Prime National Highway 1 in Bhutan

Published: April 2022

This paper presents the characteristics of surficial mass movements after cutting a slope through Prime National Highway 1 (PNH-1) in Bhutan. A surficial mass movement, in the form of slope failures, affects the ability of traffic to move along PNH-1. The geology of the area of PNH-1 consists of metamorphic rocks. There are several types of surficial mass movement in slopes – for instance, rock/soil slide, debris flow and rockfalls. Slope failure occurs due to geological discontinuities, the boundary of strata, joints and so on. From the observation of more than 100 slope failures along PNH-1, the authors classified the surficial mass movements into three types: ‘denudation’, ‘flows’ and ‘slides’. Among these three types, denudation and flows destabilise the surface layer of the slope a while after cutting, while slides tend to collapse on the slope within a short time after cutting. According to Varnes’s landslide classification, surficial mass movements such as denudation and flows are categorised as flows, and slides as slides.

Published: April 2022

Estudos sobre os grupos sanguíneos ABO e fator Rh são importantes no ramo da medicina e da biologia molecular, principalmente, por fornecerem informações quanto à disponibilidade de sangue para transfusões, e risco de ocorrência da doença hemolítica perinatal (DHP). O objetivo deste trabalho foi determinar a distribuição e frequência dos fenótipos, genótipos e alelos dos sistemas ABO e Rh entre os moradores da Comunidade Novo Cruzeiro, zona rural do município de Alta Floresta, Mato Grosso. Foram entrevistados 102 moradores, sendo que apenas 43 souberam informar o grupo sanguíneo ao qual pertencem. Em relação ao sistema Rh, 91%   são Rh+, e entre as mulheres, 9% são Rh-, o que merece atenção em função da DHP. Entre os homens, o desconhecimento quanto ao fator Rh foi maior. O grupo sanguíneo “O” foi o mais frequente (55,8%), e com relação às frequências alélicas estimadas, o alelo mais frequente foi o “i” (75%). A predominância dos grupos “O Rh+” e “A Rh+” entre os moradores pode estar relacionada ao processo de colonização e a formação das populações contemporâneas. Diante dos resultados, reconhece-se o não conhecimento, pela maioria dos moradores, quanto ao grupo sanguíneo e fator Rh ao qual pertencem, e se torna urgente a necessidade de projetos que esclareçam a população quanto à importância do conhecimento sobre o sistema ABO e fator Rh.

Abstract
Studies of blood groups ABO and Rh factor are important in the field of medicine and molecular biology, as they provide information regarding the availability of blood available for transfusions and the risk of perinatal hemolytic disease (PHD). In this context, this study aimed to determine the distribution and frequency of phenotypes, genotypes and alleles of the ABO and Rh systems among residents of Novo Cruzeiro Community, a rural area in the municipality of Alta Floresta, Mato Grosso.  102 residents were interviewed, and  only 43 able to inform the blood group to which they belong to. Regarding the Rh system, 91% are Rh +, and among women, 9% are Rh-, which deserves attention due to PHD. Among men, the lack of knowledge about the Rh factor was greater. Blood group “O” was the most frequent (55.8%), and regarding to estimated allele frequencies, the most frequent allele was “i” (75%). The predominance of the “O Rh +” and “A Rh +” groups among residents may be related to the colonization process and the formation of contemporary populations. In view of the results, it is recognized that most residents do not know about the blood group and Rh factor to which they belong to, and there is an urgent need for projects that clarify the population regarding the importance of knowledge about the ABO system and the factor Rh.

Published: April 2022

Background: To delineate the predominant clinical features of dengue infection among children in Bangladesh.Methods: A cross-sectional descriptive study was in Dhaka Shishu hospital, Dhaka, Bangladesh. All children of age <18 years admitted with suspected dengue infection starting from July 2019 till September 2019 were enrolled in this study. Demographic variables, presenting complaints and examination findings were recorded on a standard questionnaire. Data was analyzed by using SPSS version 27.Results: A total of 584 children were included in the study, of which 345 (59.1%) were male. Children ranged from age 1 month to 18 years with a mean of 5.6±4 years. Most of the children did not go to school or were less than 5 years of age 532 (91.1%). All the children presented with either high- or low-grade fever, and around half of them complained of vomiting. Notable symptoms among the children were abdominal pain in 20% cases, dehydration, and flu-like symptoms (cough and cold) in 10% of cases. Dengue warning signs were noted in 161 cases (27.6%), and vomiting was present in 43.7% of cases. Anaemia, respiratory distress, and pleural effusion were rarely noticed among the studied patients. Laboratory investigation of the dengue patients revealed that NS1 antigen was positive in 49 cases (8.4%). Haemoglobin was low in one-third of the cases, and leukopenia and thrombocytopenia were present in 23.5% and 38.7% cases, respectively. Among the dengue patients, around 12% (n=71) were infants.Conclusions: This descriptive study identifies that vomiting, abdominal pain, and dengue warning signs are the predominant clinical features of dengue infection among children in Bangladesh. Comparison with earlier studies reveals that clinical and laboratory features of dengue might vary by age, severity and region.
