ABSTRACT Introduction: Blood transfusion is one of the most common medical practices worldwide. However, current scientific literature has shown that the immunomodulatory effects of blood transfusion are associated with an increased likelihood of infection, prolonged hospitalization, and morbimortality. Also, it means high costs for healthcare systems. Methods: In this context, acknowledging that blood transfusions are essentially heterologous cell transplantations, the use of therapeutic options has gained strength and is collectively known as the patient blood management (PBM) program. PBM is an approach based on three main pillars: (1) treating anemias and coagulopathies in an optimized manner, especially in the preoperative period; (2) optimizing perioperative hemostasis and the use of blood recovery systems to avoid the loss of the patient's blood; (3) anemia tolerance, with improved oxygen delivery and reduced oxygen demand, particularly in the postoperative period. Results: Current scientific evidence supports the effectiveness of PBM by reducing the need for blood transfusions, decreasing associated complications, and promoting more efficient and safer blood management. Thus, PBM not only improves clinical outcomes for patients but also contributes to the economic sustainability of healthcare systems. Conclusion: The aim of this review was to summarize PBM strategies in a comprehensive, evidence-based approach through a systematic and structured model for PBM implementation in tertiary hospitals. The recommendations proposed herein are from researchers and experts of a high-complexity university hospital in the network of the Sistema Único de Saúde, presenting itself as a strategy that can be followed as a guideline for PBM implementation in other settings.

Abstract Food processing allows a wide variation in the final quality of the product, which directly depends on the quality of the raw material used, the processing conditions, storage and commercialization. Salting, for example, is one of the oldest methods used to preserve meat. In the meat industry, the incorporation of salts into products is commonly used to improve dietary functionality and ensure food safety. Thus, the objective of this review was to understand that the discarded matrix meat can be used to make jerky meat, adding value to the final product. The processing of jerked beef is based on the osmotic dehydration process in counter flow, promoted by the penetration of salt with consequent exit of water from the inter and extra fibrillar compartments to the surface, with subsequent drying. At the same time, myosin denaturation occurs as a result of high temperatures, as well as myoglobin oxidation, promoted by salt, increasing the susceptibility to protein oxidation. The use of discarded animal meat to make jerky adds value to the by-product, improving sensory quality.

RESUMEN El objetivo del estudio es discutir uno de los usos del crack denominado “virado”, como estrategia de reducción de daños entre las personas que usan crack en Pernambuco, Brasil. Se realizó una investigación cualitativa y transversal. Desde marzo hasta agosto de 2016, se realizaron entrevistas semiestructuradas sobre la cultura del uso de crack a 39 personas que usan esta substancia. El límite de participantes se estableció por el criterio de saturación. Los datos se analizaron con la técnica de análisis de contenido. Las personas que participaron relataron que el virado es una manera distinta de utilizar el crack y, al comparar su efecto con el uso fumado o inhalado, mencionaron que el virado produce menos impacto en las relaciones interpersonales y en la libido, además de reducir el uso compulsivo de crack, cuestiones que se podrían considerar como estrategias de reducción de daños. Un aspecto negativo es que comparten los canutos para aspirar el virado, lo cual es una situación de riesgo para la transmisión de enfermedades infecciosas. Conocer la cultura del uso del crack en distintas formas y situaciones es imprescindible para la planificación y desarrollo de acciones de atención a la salud.

ABSTRACT The aim of the study is to discuss the use of crack in the form of “virado” as a harm reduction strategy in Pernambuco, Brazil. This is a cross-sectional study with a qualitative approach in which semi-structured interviews were conducted regarding aspects related to the culture of crack use with 39 crack users between March and August 2016. Participants were recruited using saturation criteria and data were analyzed through content analysis. Respondents discussed the use of “virado” and compared its effects in relation to crack, addressing improvement in interpersonal relationships, libido, and non-compulsive drug use, which can all be understood as harm reduction strategies. On the other hand, equipment sharing for the use of “virado” was identified as a high-risk practice with regards to the transmission of infectious diseases. Knowing about the culture of crack use in different contexts is essential in order to plan and develop health care actions.

RESUMO: Foram avaliadas cinco cultivares de Zea mays (BRS Caatingueiro, BRS Gorutuba, BRS Sertanejo, BRS Asa Branca e BR 106) e seu efeito na nutrição do gorgulho-do-milho Sitophilus zeamais, por meio da análise de proteína total em adultos alimentados com esses cultivares e a presença de lectinas e inibidores da tripsina nos grãos. Além disso, foram realizados ensaios com e sem chance de escolha para investigar a resistência dos cultivares de Z. mays ao ataque de S. zeamais. O cultivar BR 106 apresentou o menor índice de susceptibilidade, seguido por BRS Caatingueiro, BRS Asa Branca, BRS Sertanejo e BRS Gorutuba. O número de adultos emergidos nos cultivares de Z. mays variou de 213,17 a 74,0, e o menor número de insetos foi registrado para o cultivar BR 106. Os insetos foram capazes de se alimentar de todos os cultivares, no entanto, o BR 106 mostrou a menor redução na biomassa seca. As lectinas foram detectadas em extratos de BR 106, BRS Asa Branca, BRS Sertanejo e BRS Gorutuba, e a maior atividade foi demonstrada pela BR 106. A menor assimilação de proteína foi detectada nos insetos que se alimentaram com BRS Asa Branca. Os extratos de todos os cultivares foram capazes de inibir a atividade da tripsina bovina, mas esse efeito não está correlacionado ao grau de resistência dos cultivares de Z. mays. Os resultados sugerem a resistência da BR 160 ao ataque de S. zeamais, além de indicar que a presença de lectina nos grãos é a causa dessa resistência.

ABSTRACT: Five Zea mays cultivars (BRS Caatingueiro, BRS Gorutuba, BRS Sertanejo, BRS Asa Branca and BR 106) were evaluated considering their effect on the nutrition of the maize weevil Sitophilus zeamais, by analysis of total protein in adult fed with these cultivars and for the presence of lectins and trypsin inhibitors in grains. In addition, free-choice and no-choice assays were performed to investigate the resistance of grains of the Z. mays cultivars to an attack by S. zeamais. The BR 106 cultivar showed the lowest susceptibility index, followed by BRS Caatingueiro, BRS Asa Branca, BRS Sertanejo and BRS Gorutuba. The number of emerged adults in the Z. mays cultivars ranged from 213.17 to 74.0, and the lowest number of insects was recorded for the BR 106 cultivar. The insects were able to feed on grains of all cultivars, but the BR 106 cultivar showed the least reduction in dried biomass. Lectins were detected in extracts from BR 106, BRS Asa Branca, BRS Sertanejo and BRS Gorutuba, and the highest activity was shown by BR 106. The lowest protein assimilation was detected in the insects from treatments with BRS Asa Branca. The extracts from all cultivars were able to inhibit the activity of bovine trypsin, but this effect was not related to the resistance degree of Z. mays cultivars. The results suggest the resistance of BR 160 to the attack of S. zeamais, as well as indicating that the presence of lectin in the grains is the cause of this resistance.

ABSTRACT: Ankylosis is an anomaly of tooth eruption characterized by the fusion of cementum and alveolar bone, and may affect from small regions to the entire root surface. Clinical assessment combined with imaging exams can aid diagnosis. Radiographic testing enables assessing only proximal regions of possibly affected roots. Whereas cone beam computed tomography (CBCT) allows a three-dimensional assessment of axial, coronal, and sagittal planes of all dental extension, eliminating thus overlapping images and helping to confirm the correct diagnosis. The present study contains a case report of a male patient with ankylosis in tooth 16 diagnosed by CBCT, aiming at providing information for dentists about this anomaly, its characteristics and situations in which CBCT should be indicated.

RESUMEN: La anquilosis es una anomalía de la erupción del diente caracterizada por la fusión de cemento y hueso alveolar, y puede afectar desde pequeñas regiones hasta toda la superficie de la raíz. La evaluación clínica combinada con los exámenes de imagen puede ayudar a diagnosticar esta anomalía. Las pruebas radiográficas permiten evaluar sólo las regiones proximales de las raíces posiblemente afectadas. La tomografía computarizada de haz de cono (CBCT) permite una evaluación tridimensional de los planos axial, coronal y sagital de toda la extensión dental, eliminando así las imágenes superpuestas y ayudando a confirmar el diagnóstico correcto. En el presente estudio se presenta un reporte de caso de un paciente con anquilosis en el diente 16 diagnosticado por CBCT, con el objetivo de proporcionar información para los dentistas sobre esta anomalía, sus características y situaciones en las que debe indicarse la CBCT.

RESUMO A displasia fibrosa é uma lesão fibro-óssea benigna em que o osso normal é substituído por tecido conjuntivo fibroso e osso imaturo, podendo afetar um único osso (monostótica) ou vários ossos (poliostótica), ocorrendo principalmente em crianças e adultos jovens. Quando presente nos ossos faciais, a maxila é envolvida com mais frequência que a mandíbula, podendo causar assimetria facial, além de complicações odontológicas. Nos exames por imagem a característica principal da displasia fibrosa é a aparência de vidro despolido. A tomografia computadorizada é o método ideal para avaliação dessa lesão e relação com estruturas adjacentes. A radiografia convencional, devido a sobreposição de estruturas anatômicas, torna difícil a delimitação da extensão da lesão. O presente estudo teve como objetivo apresentar o relato de caso de um paciente do sexo feminino, 10 anos de idade, com presença de displasia fibrosa na maxila, objetivando orientar os cirurgiões-dentistas com relação às principais características imaginológicas dessa lesão.

ABSTRACT Fibrous dysplasia is a benign fibrous-osseous lesion in which normal bone is replaced by fibrous connective tissue and immature bone, affecting only one (monostotic) or several bones (polyostotic) and mainly occurring in children and young adults. When present in facial bones, the maxilla is more frequently involved than the mandible, which can cause facial asymmetry in addition to dental complications. In the image exams, the main characteristic of fibrous dysplasia is its unpolished glass appearance. Computed tomography is the ideal method for evaluating this lesion and its relationship with adjacent structures. The use of conventional radiography, due to the overlapping of anatomical structures, makes it difficult to delineate the extension of the lesion. The present study is aimed at guiding dentist-surgeons on the main imaging characteristics of fibrous dysplasia by describing a case of a female 10-year-old patient presenting with this lesion in the maxilla.

The aim of this report is to present a case of dens invaginatus asymptomatic discovered after exam cone beam computed tomography. A 20-year-old patient attended the clinic Radiology to perform tomography to fracture research at the root of the tooth 15. However, the examination was observed the presence of a conoid supernumerary tooth between the tooth located roots 11 and 12, which had a hyperdense line to the apex of the root, representing the invagination of the enamel, dens invaginatus feature. It was also observed extensive hypodense image in the periapical region, with areas of external resorption both in supernumerary tooth as we ll as the roots of teeth 11 and 12. The treatment consisted of surgery for dens invaginatus extraction. The dentists should be aware of the imaginological characteristics of the anomalies that can affect the teeth/jaws, which can be discovered in tests for routine imaging and proper conduct for the treatment of patients.

Un paciente de 20 años de edad acudió a la clínica radiológica para realizarse una tomografía producto una fractura radicular del diente 15. Sin embargo, en el exámen se observó la presencia de un diente supernumerario cónico localizado entre las raíces de los dientes 11 y 12, observando además una línea hiperdensa hacia el ápice de la raíz, que representa la invaginación del esmalte, característica propia de undens invaginatus.También se observó un área hipodensa en la región periapical, con áreas de reabsorción externa tanto en el diente supernumerario como en las raíces de los dientes 11 y 12. El tratamiento consistió en cirugía de extracción deldens invaginatus. Los dentistas deben conocer las características imagenológicas de las anomalías que pueden afectar a los dientes, las cuales pueden ser descubiertas en exámenes de rutina y también el protocolo adecuado de tratamiento de éstas.

Gliomas are the most common type of primary central nervous system neoplasm. Astrocytomas are the most prevalent type of glioma and these tumors may be influenced by sex steroid hormones. A literature review for the presence of estrogen and progesterone receptors in astrocytomas was conducted in the PubMed database using the following MeSH terms: “estrogen receptor beta” OR “estrogen receptor alpha” OR “estrogen receptor antagonists” OR “progesterone receptors” OR “astrocytoma” OR “glioma” OR “glioblastoma”. Among the 111 articles identified, 13 studies met our inclusion criteria. The majority of reports showed the presence of estrogen and progesterone receptors in astrocytomas. Overall, higher tumor grades were associated with decreased estrogen receptor expression and increased progesterone receptor expression.

ABSTRACT: Children with cerebral palsy (CP) present motor disability and may have fewer sensorimotor experiences, which may interfere in their main activity: playing. The purpose of this study was to identify the perceptions of parents and occupational therapists on the ludic behavior of children with CP. The study was carried out with 25 children with CP using Initial Interview with Parents and Assessment of Ludic Behavior aimed at occupational therapists. Results indicated an agreement rate ranging from 8% to 93%; regarding the child's General Interest to Other People; from 88% to 100% for Child's General Interest for the Sensorial Environment; from 84% to 96% in the category Ludic Interests and Skills; and from 68% to 100% in the category Characteristics of the Ludic Attitude. The instruments used were capable of identifying the children's ludic behavior and may help define the objectives and treatment plan with a patient-centered approach. This study showed that children with CP, regardless of their motor severity, demonstrate attitude, action and interest in playing, consistently to the Ludic Model.

RESUMO INTRODUÇÃO: A proximidade das raízes com o seio maxilar pode criar uma variedade de riscos. OBJETIVO: Avaliar a relação entre as raízes dos dentes hígidos com o seio maxilar, assim como com a ocorrência de doenças sinusais. MÉTODO: Três radiologistas analisaram 109 imagens de tomografia computadorizada de feixe cônico (TCFC). O teste Kappa avaliou a concordância intra e interexaminadores. Os testes de Qui-quadrado e Razão de Prevalência foram utilizados para testar a hipótese de que raízes de dentes hígidos dentro do seio maxilar favorecem a ocorrência doenças sinusais (nível de significância = 0,01). RESULTADOS: A concordância intra e interexaminadores variou de boa a excelente. O teste Qui-quadrado mostrou uma diferença estatisticamente significante (p = 0,006) entre as raízes dentárias dentro do seio maxilar patológico (6,09%) e aquelas dentro do seio normal (3,43%). O teste de Razão de Prevalência mostrou uma ocorrência de raízes dentárias dentro de seios patológicos estatisticamente maior do que dentro de seios normais (p < 0,0001). As raízes dentro do seio maxilar foram encontradas 1,82 vezes mais associadas a seios patológicos. CONCLUSÃO: Raízes dentárias dentro do seio maxilar são quase duas vezes mais associadas a seios patológicos do que a seios normais. Dentes hígidos que têm raízes dentro do seio maxilar podem induzir uma resposta inflamatória da mucosa sinusal. Suspeita-se que procedimentos odontológicos possam agravar tal situação.

ABSTRACT INTRODUCTION: The proximity of the roots to the maxillary sinus can create a variety of risks. OBJECTIVE: To evaluate the relationship between the roots of healthy teeth and the maxillary sinus, as well as the occurrence of sinus pathologies. METHODS: Three radiologists analyzed 109 cone beam computed tomography (CBCT) images. The Kappa test was used to assess the intra- and inter-rater agreement. The chi-squared test and prevalence ratio were used to test the hypothesis that roots of healthy teeth in the maxillary sinus favored the occurrence of sinus pathologies ( p = 0.01). RESULTS: Intra- and inter-rater agreement ranged from good to excellent. The chi-squared test demonstrated a statistically significant difference ( p = 0.006) between the tooth roots in diseased maxillary sinuses (6.09%) and those in normal sinuses (3.43%). The prevalence ratio test showed a statistically significant higher prevalence of tooth roots in diseased sinuses than in normal sinuses ( p < 0.0001). Roots in the maxillary sinus were 1.82 times more associated with diseased sinuses. CONCLUSION: Dental roots in the maxillary sinus are almost twice as likely to be associated with diseased sinuses than normal sinuses. Healthy teeth whose roots are inside the maxillary sinus may induce an inflammatory response in the sinus membrane. It is suspected that dental procedures may exacerbate the condition.

Abstract The purpose of this study was to perform a microcomputed tomographic evaluation of the radioprotective effect of resveratrol on the volume of mandibular incisors of irradiated rats. A second aim was to make a quantitative assessment of the effect of x-ray exposure on these dental tissues. Twenty adult male rats were divided into four groups: control, irradiated control, resveratrol, and irradiated resveratrol. The resveratrol groups received 100 mg/kg of resveratrol, whereas the irradiated groups were exposed to 15 Gy of irradiation. The animals were sacrificed 30 days after the irradiation procedure, and their mandibles were removed and scanned in a microcomputed tomography unit. The images were loaded into Mimics software to allow segmentation of the mandibular incisor and assessment of its volume. The results were compared by One-way ANOVA and Tukey’s post hoc test, considering a 5% significance level. The irradiated groups showed significantly diminished volumes of the evaluated teeth, as compared with the control group (p < 0.05). The resveratrol group presented higher values than those of the irradiated groups, and volumes similar to those of the control group. High radiation doses significantly affected tooth formation, resulting in alterations in the dental structure, and thus lower volumes. Moreover, resveratrol showed no effective radioprotective impact on dental tissues. Future studies are needed to evaluate different concentrations of this substance, in an endeavor to verify its potential as a radioprotector for these dental tissues.
