Abstract Introduction Mindfulness-based interventions (MBI) have been growing progressively as treatment options in the field of mental health. Aim: To assess the impact of mindfulness-based interventions for reducing suicidal thoughts and behaviors. Methods A systematic review was performed in December 2020 using PubMed, PsycINFO, EMBASE, SciELO, Pepsic, and LILACS databases with no year restrictions. The search strategy included the terms (‘mindfulness’ OR ‘mindfulness-based’) AND (‘suicide’ OR ‘suicidal’ OR ‘suicide risk’ OR ‘suicide attempt’ OR ‘suicide ideation’ OR ‘suicide behavior’). The protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO), CRD42020219514. Results A total of 14 studies met all inclusion criteria and were included in this review. Most of the studies presented Mindfulness-Based Cognitive Therapy as the MBI assessed (n=10). An emerging and rapidly growing literature on MBI presents promising results in reduction of suicide risk, particularly in patients with MDD. Four studies assessing other MBI treatment protocols (Mindfulness-Based Stress Reduction; Daily Mindfulness Meditation Practice; Mind Body Awareness and Mindfulness-Based Cognitive Behavior Therapy) all demonstrated that MBI reduces factors associated with suicide risk. Conclusion MBI might target specific processes and contribute to suicide risk reduction.

Abstract Objective: To evaluate the barriers to access and oral health care faced by children and adolescents with Cerebral Palsy (CP) according to their motor impairment through the perception of caregivers. Material and Methods: A case series study was carried out at three health institutions in Pernambuco, Brazil. The study sample consisted of 94 caregivers of 5-to-18-year-old patients with CP, according to GMFCS (The Gross Motor Function Classification System). Data were collected using a semi-structured form to evaluate the barriers to access and analyzed statistically by the chi-square and Fisher exact tests, adopting a 5% level of significance. In addition, binary logistic regression was performed to determine the weight of the variables in explaining the outcome variable. Results: There were major difficulties involving transportation (p=0.04) and structural accessibility to dental services (p<0.01) among children and adolescents with severe CP. In addition, the more severe the CP, the greater the difficulty of accessibility (OR=4.09,) and the lower the income (OR=8.80), the greater the motor impairment. Conclusion: Despite the availability of access to dental services, low-income families have more severe CP patients, contributing to the daily difficulties already faced by them in oral health care.

Resumo Rangelia vitalii infecta eritrócitos, leucócitos e células endoteliais de cães. O presente estudo objetivou relatar a detecção molecular confirmada por sequenciamento de R. vitalii no estado do Paraná e descrever as alterações clínicas, hematológicas e bioquímicas dos cães infectados. Três cães doentes da região metropolitana de Curitiba, PR, Brasil, foram submetidos a exame físico e exames laboratoriais que incluíram hematologia, bioquímica, reação em cadeia da polimerase (PCR) e sequenciamento genético. Os sinais clínicos incluíram apatia, anorexia e hemorragia. Piroplasmas intra-eritrocíticos e extracelulares foram encontrados em esfregaços de sangue periférico dos três cães. As amostras de sangue destes animais foram positivas para Babesia sp. pela PCR baseada no gene 18S rRNA. Os produtos de PCR dos três cães foram sequenciados e a análise de BLAST mostrou que as seqüências geradas por PCR eram altamente homólogas com as de R. vitalii previamente relatadas. Os achados hematológicos incluíram anemia grave, desvio de neutrófilos à esquerda regenerativo e trombocitopenia. Os níveis de uréia no soro aumentaram nos três cães, e os níveis de bilirrubina direta foram elevados em um cão.

Abstract Rangelia vitalii infects erythrocytes, leukocytes and endothelial cells of dogs. The present study aimed to report the molecular detection confirmed by sequencing of R. vitalii in the state of Paraná, as well as describe the clinical, hematological and biochemical alterations of the infected dogs. Three sick dogs from the metropolitan area of Curitiba, PR, Brazil, underwent a physical exam, and laboratory tests included hematology, biochemistry, polymerase chain reaction (PCR), and gene sequencing. Clinical signs included apathy, anorexia, and hemorrhage. Intra-erythrocytic and extracellular piroplasms were found on peripheral blood smears from all three dogs. Blood samples from these animals were positive for Babesia sp. by PCR targeting 18S rRNA. PCR products from all three dogs were sequenced, and BLAST analysis showed that the PCR-generated sequences were highly homologous with those of R. vitalii previously reported. Hematologic findings included severe anemia, shift of neutrophils to the regenerative left, and thrombocytopenia. Serum urea levels were increased in all three dogs, and direct bilirubin levels were elevated in one dog.

Measles is a human infectious disease of global concern that is caused by the measles virus. In this study, we report the complete genome sequencing of one measles virus isolate, genotype D8, that was obtained directly from a urine sample in Boa Vista city, the capital of Roraima state in Brazil. Phylogenetic reconstruction grouped the genome described in this study with that of samples from Australia, South Korea, and Italy. To our knowledge, this is the first complete genome sequence of a wild-type measles virus reported from Latin America. Therefore, the present data strengthen the current knowledge on the molecular epidemiology of measles worldwide.

The non-melanoma skin cancer is the most common cancer and accounts for more than half of the diagnoses of cancer, and basal cell carcinoma (BCC), the most frequent cutaneous neoplasm, corresponding to 70-80% of cutaneous tumors. Oxidative stress is an important trigger for skin carcinogenesis. Thus, it is important to evaluate oxidative stress, in order to discern effective therapeutic strategies able to stop it or attenuate it, thereby prevent the installation of non-melanoma skin cancer. Cross-sectional study with controls, involving 84 individuals of both sexes aged between 38-84 years, divided into two groups: control group of healthy people( n = 24) and the case group included individuals who presented non-melanoma skin and they have undergoing surgery (n = 60). The blood samples of the individuals were obtained for evaluation of biomarkers of oxidative stress (F2-isoprostane, nitrite, thiobarbituric acid reactive substances (TBARS) and total antioxidant capacity). The usual dietary intake and nutritional status of the subjects were evaluated. The significance level for this study was 5%. Patients in the case group had higher serum concentrations of biomarkers of oxidative stress, F2-isoprostane concentrations were significantly higher compared to controls. The results showed high rates of overweight and obesity in the case and control groups. The dietary concentrations of antioxidant minerals zinc, copper and selenium in the case group were significantly lower compared to controls. The correlation between markers of oxidative stress and dietary concentrations of antioxidant nutrients showed the influence of food intake of vitamins A and E in reducing oxidative stress, since these nutrients behave as important antioxidants, acting as sweepers of RL, by removing of the body the negative effects on the redox balance of the skin. We emphasize the importance of adopting healthy eating habits that optimize the consumption of antioxidant nutrients as a strategy to prevent oxidative damage to the skin.

El cáncer de piel no melanoma es el cáncer más común y representa más de la mitad de los diagnósticos de cáncer, y el carcinoma de células basales (BCC), la neoplasia cutánea más frecuente, representando el 70-80% de los tumores cutáneos. El estrés oxidativo es un disparador importante en la carcinogénesis de la piel. Por lo tanto, es importante para evaluar el estrés oxidativo, con el fin de prever y estrategias terapéuticas eficaces capaces de detener o mitigar ella, para evitar de este modo la instalación de cáncer de piel no melanoma. Estudio transversal con los controles, con la participación de 84 sujetos de ambos sexos con edades comprendidas entre 38 a 84 años, divididos en dos grupos: grupo control de sujetos sanos (n = 24) personas y el grupo de casos incluyeron los individuos que presentaron para el cáncer de piel no melanoma tiene someterse a la cirugía (n = 60). Las muestras de sangre de los sujetos fueron obtenidos para la evaluación de los biomarcadores de estrés oxidativo (F2-isoprostano, nitritos, sustancias reactivas al ácido tiobarbitúrico (TBARS) y capacidad antioxidante total). Se evaluó la ingesta dietética habitual y el estado nutricional de los sujetos. El nivel de significación para este estudio fue de 5%. Los pacientes en el grupo de casos tenían mayores concentraciones séricas de biomarcadores de estrés oxidativo, las concentraciones de F2-isoprostano fueron significativamente mayor en comparación con los controles. Los resultados mostraron altas tasas de sobrepeso y obesidad en los grupos de casos y controles. Las concentraciones dietéticas de antioxidante minerales de zinc, cobre y selenio en el grupo de casos fueron significativamente más bajos en comparación con los controles. La correlación entre los marcadores de estrés oxidativo y las concentraciones dietéticas de nutrientes antioxidantes destacó la influencia de la ingesta de alimentos de vitaminas A y E en la reducción del estrés oxidativo, ya que estos nutrientes se comportan como antioxidantes importantes, actuando como barrenderos RL, el cuerpo se deshaga de estos efectos negativos sobre el equilibrio redox de la piel. Hacemos hincapié en la importancia de adoptar hábitos de alimentación saludables que optimizan el consumo de nutrientes antioxidantes como estrategia para prevenir el daño oxidativo de la piel.

This research presents a breakdown of activities performed by a group of students, tutors and preceptors as a proposal of the PET-Health Project of Marília College of Medicine in partnership with Municipal Health Secretary of Marília. Having proposed to analyze the reasons for nonadherence to a community's educational actions nine interviews were conducted with users who, having been invited to participate in education actions within a group, did not attend. Data analysis allowed the development of three units of meaning, which revealed the difficulty of exercising citizenship and the incompatibility with wishes and possibilities of the community; disinterest of the population and the emphasis on the biomedical model permeating healthcare actions, and indications for developing such actions. Facing the challenges to be confronted when glimpsing changes in the care model, it is believed that there is a necessity to review the process of team work and to recognize that changes happen in a slow and gradual way.

Este estudio presenta el desglose de actividades de un grupo de estudantes, tutores y preceptores que forman parte de una propuesta del Proyecto PET-Salud de la Facultad de Medicina de Marília juntamente con la Secretaria Municipal de Salud de dicha ciudad. Con la propuesta de analizar los motivos de la no adhesión de una comunidad a las acciones educativas, fueron realizadas nueve entrevistas con usuarios que no se presentaron a las acciones educativas en grupo. Las entrevistas fueron grabadas y transcritas. El análisis de datos permitió elaborar tres núcleos de sentido: dificultad en ejercer la ciudadanía e incompatibilidad con los deseos y posibilidades de la comunidad; desinterés de la población y énfasis en el modelo biomédico que impregna las acciones de salud y, finalmente, indicaciones para desarrollar tales acciones. Ante el reto de los cambios en el modelo de atención, es importante considerar la necesidad de rever el proceso de trabajo del equipo y reconocer que los cambios suceden de forma lenta y gradual.

O presente estudo apresenta um desdobramento das atividades realizadas por um grupo de estudantes, tutores e preceptores, que compõe uma proposta do Projeto PET-Saúde da Faculdade de Medicina de Marília em parceria com a Secretaria Municipal de Saúde de Marília. Tendo como proposta analisar os motivos da não adesão de uma comunidade às ações educativas, foram realizadas nove entrevistas com usuários que, convidados para ações educativas em grupo, não compareceram. As entrevistas foram gravadas e transcritas. A análise dos dados possibilitou a elaboração de três núcleos de sentido, os quais revelaram a dificuldade em exercer a cidadania e incompatibilidade com os desejos e possibilidades da comunidade; o desinteresse da população e a ênfase no modelo biomédico permeando as ações de saúde e indicações para desenvolver tais ações. Frente aos desafios a serem enfrentados ao se vislumbrarem mudanças no modelo de atenção, acredita-se na necessidade de rever o processo de trabalho da equipe e reconhecer que as mudanças acontecem de forma lenta e gradual.

A freqüência do vírus Epstein-Barr (EBV) em pacientes com linfoma de Hodgkin Clássico (LHC) sofre variabilidade geográfica. No presente estudo investigamos a freqüência do EBV em pacientes com LHC no estado do Ceará. Trinta e sete casos de linfoma de Hodgkin clássico foram avaliados por imuno-histoquímica para EBV usando o anticorpo monoclonal contra a proteína latente da membrana (LMP1) e pelo método de hibridização in situ para RNA associado ao EBV (EBER1). Não há diferença por sexo e idade dos pacientes no que concerne à freqüência de LHC. O subtipo histológico esclerose nodular foi predominante. LMP1 esteve presente em células Reed-Sternberg em 67,5% e pela hibridização in situ, através da sonda EBER, foi evidente em 75,6% dos casos. Não observamos predominância significativa da associação de EBV com os subtipos histológicos esclerose nodular (EN) e celularidade mista (CM) (p = 0,66).

The prevalence of Epstein-Barr virus (EBV) in patients with classical Hodgkin’s lymphoma (CHL) is geographically variable. In the present study the prevalence of EBV in CHL was assessed in adult patients from Ceará, Brazil. Thirty-seven cases were immunohistochemically evaluated for EBV using latent membrane protein (LMP1) antibody and for EBV latency-associated RNA (EBER1) using in situ hybridization (ISH). Sex and age did not differ among patients as to the frequency of CHL. Nodular sclerosis was the predominant histological subtype. LMP1 was found in Reed-Sternberg cells in 67.5% of the cases whereas ISH detected EBER1 in 75.6%. Regarding histological subtypes EBV infection rates were not found statistically different in nodular sclerosis (NS) and mixed cellularity (MC) subtypes (p = 0.66).

Pesquisou-se o nível de desgaste dental (atrição e/ou abrasão) em 168 espécimes de Didelphis albiventris e D. marsupialis (gambás) do sul do Brasil. O desgaste foi muito importante, com elevada freqüência de dentina terciária e de exposição da câmara coronária e/ou do canal radicular, devido à associação de fraturas e desgaste, pois as fraturas predispõem ao desgaste e este favorece as fraturas. O grau de desgaste aumentou com a idade dos animais. A ordem crescente na freqüência de dentina terciária nos dentes caudais aos caninos foi: primeiro, segundo e terceiro molares, terceiro e segundo pré-molar, e quarto molar. Diferentemente de outros onívoros, em Didelphis o desgaste dentário parece mais relacionado às fraturas devidas aos alimentos (seguida de atrição/abrasão) do que ao contato entre os dentes. Ao contrário da literatura, os molares tribosfênicos não parecem "ideais" para tal dieta onívora, o que é evidenciado pela elevada freqüência de desgaste, fraturas e exposição da câmara coronária ou do canal radicular.

This work deals with the study of dental wear down (atrittion and/or abrasion) in 168 specimens of Didelphis albiventris and D. marsupialis from Southern Brazil. Wear down was very important, with high frequency of tertiary dentine and exposition of the pulp cavity/radicular canal, due to the association of fractures and wear down. Fractures predispose wear down which, on the other side, favors fractures. The degree of attrition increased with age. The order of growing frequency of tertiary dentin in poscanines was: first, second and third molars, third and second premolars, and finally fourth molar. Differently from others omnivorous in Didelphis tooth wear down seems rather related to fractures due to food (followed by attrition) than to teeth contact. Contrary to literature, tribosphenic molars seems not to be "ideals" for such omnivorous diet, as is evident from the high frequency of wear down, fractures and teeth cavities exposition.
