ABSTRACT

The puma (Puma concolor Linnaeus, 1771), the most widely distributed felid species in the Americas, can be found in all Brazilian biomes. Nevertheless, few studies have focused on hemoparasites in this species. Cytauxzoon felis, a hemoparasite that can infect domestic cats, has also been described in wild felids in Brazil. To the best of our knowledge, this study is the first to diagnose the natural infection and molecular detection of C. felis in a P. concolor in the state of Goiás. This animal presented non-regenerative anemia and inclusion suggestive of piroplasmids within red blood cells. The amplified 551 bp fragment of partial Piroplasmida 18S rRNA gene sequence was 100% identical to corresponding sequences of C. felis available in GenBank. No specific treatment for cytauxzoonosis was administered, and after rehabilitation, the animal was reintroduced into the wild. This finding provides some evidence that P. concolor may act as a natural host of the parasite. The epidemiology, vector and pathogenicity of this hemoparasite in wild and domestic cats in Brazil deserves further investigation.


O puma (Puma concolor Linnaeus, 1771) tem a maior distribuição entre os felídeos das Américas e é encontrado em todos os biomas do Brasil. No entanto, poucos estudos têm se concentrado nos hemoparasitos nesta espécie. Cytauxzoon felis, um hemoparasito que pode infectar gatos domésticos, também foi descrito em felídeos selvagens no Brasil. A saber, este estudo é o primeiro diagnóstico de infecção natural e detecção molecular de C. felis em um P. concolor do estado de Goiás. Este animal apresentou anemia arregenerativa e inclusão de piroplasmídeos nos glóbulos vermelhos. A amplificação do fragmento de 551 pb da sequência parcial do gene Piroplasmorida 18S rRNA foi 100% idêntica a sequências correspondentes de C. felis disponíveis no GenBank. Nenhum tratamento específico para citauxzoonose foi administrado e, após a reabilitação, o animal foi reintroduzido na natureza. Essa descoberta fornece algumas evidências de que P. concolor pode atuar como um hospedeiro natural do parasito. A epidemiologia, vetor e patogenicidade deste hemoparasito em gatos selvagens e domésticos no Brasil merecem uma investigação mais aprofundada.

ABSTRACT

O objetivo do estudo foi analisar o estágio de desenvolvimento motor de escolares do ensino Fundamental II em Instituições públicas e privadas, por meio da habilidade motora salto vertical. Participaram do estudo 79 escolares da zona leste da cidade de São Paulo / SP, matriculados no Ensino Fundamental II. Os instrumentos utilizados de medidas antropométricas foram uma balança de bioimpedância, estadiômetro, filmadora digital e a Sistemática de Avaliação do Padrão Motor de crianças no Salto Vertical proposta por Araujo. De acordo com os resultados foi observado (26-32,9%) dos participantes no estágio Inicial, (47-59,5%) no estágio Emergentes Elementar e (6-7,6%) no estágio Proficiente. Constatou-se uma incidência elevada no estágio Emergentes Elementar (47-59,5%), o que sugere que o desenvolvimento motor para o salto vertical não está adequado para a faixa etária. Os resultados se diferem do que sugere a Teoria de Gallahue, pois, para a faixa etária dos participantes desse estudo, os mesmos deveriam apresentar padrões de movimentos fundamentais consistentes e proficientes. Essa discordância com a Teoria de Gallahue pode estar associada a quantidade e a qualidade dos estímulos presentes nessa fase que compreende os participantes do estudo, influenciando diretamente o desenvolvimento, esses fatores não foram controlados por esse estudo. (AU)


The objective of the study was to analyze the stage of motor development of elementary schoolchildren in public and private institutions, through motor skill vertical jump. The study was attended by 79 schoolchildren from the eastern zone of the city of São Paulo / SP, enrolled in Elementary School II. The instruments used for anthropometric measurements were: a bioimpedance scale, stadiometer, digital camcorder and the Child Motor Pattern Assessment Systematic in the Vertical Jump proposed by Araujo. According to the results (26-32.9%) of the participants in the Initial stage, (47-59.5%) in the Emergents Elementary stage and (6-7.6%) in the Proficient stage. There was a high incidence in the Emergentes Elemental stage (47-59.5%), which suggests that motor development for vertical jump is not adequate for the age group. The results differ from those suggested by the Gallahue Theory, since, for the age group of the participants of this study, they should present consistent and proficient fundamental movement patterns. This disagreement with the Gallahue Theory may be associated with the quantity and quality of the stimuli present in this phase that comprises study participants, directly influencing the development, these factors were not controlled by this study.

ABSTRACT

Abstract Herpetic whitlow is a viral infection of the fingers caused by the herpes simplex virus. The disease has a bimodal age distribution, affecting children under 10 years of age and young adults between 20 and 30 years old. It can be easily mistaken for panaritium or bacterial cellulitis. In patients with AIDS, atypical, chronic and recurrent ulcerated lesions occur. The Tzanck test allows a quick and low-cost diagnosis of herpes simplex virus infection. The authors report the case of a child with AIDS with painful finger ulcers in which the diagnosis was confirmed by the Tzanck test.

ABSTRACT

Resumo: Introdução: O período do internato para um estudante de Medicina é complexo e demanda atenção das escolas médicas em relação à saúde mental desses médicos em formação. Objetivo: Este estudo teve como objetivo avaliar os fatores associados aos níveis de ansiedade em estudantes internos de Medicina. Método: Trata-se de um estudo transversal analítico com abordagem quantitativa. Aplicaram-se dois questionários: um com dados sociodemográficos, pessoais e clínicos, e o Inventário de Ansiedade de Beck (BAI). Resultados: Foram incluídos na pesquisa 140 estudantes internos de um curso de Medicina. A maioria tinha até 24 anos (67,9%) e 70,7% eram do sexo feminino. Dos participantes, 54,2% eram solteiros, 31% eram adeptos de uma religião e 68,3% moravam com familiares. Na comparação dos aspectos sociodemográficos com os níveis de ansiedade, identificou-se, no sexo feminino, uma frequência bem maior de ansiedade leve e moderada do que no sexo masculino (p = 0,0133). Aspectos pessoais e clínicos comparados com os níveis de ansiedade mostraram uma frequência maior de ansiedade em estudantes que afirmaram realizar terapia psiquiátrica ou psicológica (p = 0,0110). Ter insônia esteve relacionado com ansiedade de moderada a severa (p < 0,0001). A utilização de substâncias que alteram o sono foi associada com maior frequência a todos os níveis de ansiedade (p = 0,0099). A satisfação com o rendimento acadêmico teve menor relação com os níveis de ansiedade (p = 0,0017). Entretanto, maiores frequências de ansiedade de moderada a severa e ansiedade severa foram encontradas nos alunos que afirmaram ter pensado em abandonar o curso de Medicina (p = 0,0239). Conclusão: O presente estudo revelou os aspectos sociodemográficos, pessoais e clínicos, e, consequentemente, os fatores de risco que estão mais associados ao nível de ansiedade em estudantes internos de Medicina. Ademais, expõem-se as consequências que os níveis de ansiedade podem provocar em um indivíduo, sendo imprescindível a adoção de medidas para combater e prevenir o desenvolvimento de sintomas ansiosos.


Abstract: Introduction: The internship period for a medical student is complex and demands attention from medical schools regarding the mental health of these trainee doctors. Objective: Accordingly, the aim of this study was to assess factors associated with anxiety levels among medical interns. Method: A cross-sectional analytical study with a quantitative approach. Two questionnaires were applied, one with sociodemographic, personal and clinical data and the other consisting of the Beck Anxiety Inventory (BAI) Results: 140 medical students were included in the research. Most of the students were 24 years old or under (67.9%); 70.7% were female. The majority were single (54.2%), and lived with family members (68.3%), while 31% reported having a religion. When correlating sociodemographic aspects to levels of anxiety, a much higher frequency of females with mild and moderate anxiety was identified than that of males (p = 0.0133). Personal and clinical aspects compared to the levels of anxiety showed a higher frequency of anxiety in all levels of students who claimed to undergo psychiatric or psychological therapy (p = 0.0110). Suffering from insomnia is related to moderate to severe anxiety (p <0.0001). Using substances that alter sleep is related to a higher frequency of students at all levels of anxiety (p = 0.0099). Satisfaction with academic performance is less related to anxiety levels (p = 0.0017). However, higher frequency in students with moderate to severe and severe anxiety were found in those who reported having already contemplated leaving medical school (p = 0.0239). Conclusion: This study revealed the sociodemographic, personal and clinical aspects and, consequently, the risk factors that are most frequently associated to anxiety in medical interns. Furthermore, it exposes the consequences that the variable levels of anxiety can have on an individual, and it is essential to adopt measures to combat and prevent the development of anxiety symptoms.

ABSTRACT

Abstract Background: Resistant hypertension (RH) consists of increased blood pressure (BP) despite the use of 3 or more antihypertensives or BP control only when is use of 4 or more antihypertensives. It is fundamental to exclude pseudoresistance, which can be attributed to poor therapeutic adherence. Adherence evaluation, generally by the Morisky-Grenn test, is important because, when appropriate, it is associated with fewer cardiovascular complications and better BP control. Objectives: To evaluate the adherence of patients with RH and to investigate its relation with epidemiological, anthropometric and clinical characteristics, as well as to estimate the prevalence of pseudoresistance and to outline strategies to improve adherence. Methods: Retrospective observational cohort from an interview with patients followed at an outpatient clinic for RH. Therapeutic adherence, demographic, anthropometric data, cardiovascular risk factors, comorbidities, complementary exams and BP level were collected. One-way ANOVA and Student's t-tests were used for normal variables, and the Kruskal-Wallis and Mann-Whitney tests were used for non-normal tests. Categorical variables were compared using the Chi-Square test. We considered a 5% significance level in all tests. Results: 217 individuals were included. Of these, 17% had poor adherence. Epidemiological and clinical characteristics, complications, comorbidities, BP level or drugs used were statistically insignificant between groups. The poor adherence group used significantly more drugs (p = 0.0313) and 28% of pseudoresistance was estimated. Conclusions: Most of the individuals presented good therapeutic adherence by the Morisky test. Only the number of antihypertensive drugs had a statistically significant influence on adherence, while the epidemiological, anthropometric and clinical characteristics were statistically insignificant.

ABSTRACT

RESUMO: Modelo do Estudo: Relato de caso. Importância do problema: No mundo, mais de três milhões de pessoas estão vivendo com deficiência física devido à hanseníase. O Brasil é o segundo país com o maior número de casos novos registrados.A magnitude e o alto risco de incapacidade mantêm a doença como problema de saúde pública. O diagnóstico de hanseníase em geral é simples. Porém, quadros com ausência de lesões cutâneas características, somente com alterações neurais, representam um desafio para o diagnóstico diferencial com outras doenças neurológicas. Comentários: Relatamos o caso de um paciente encaminhado ao serviço de neurologia com história clínica e eletroneuromiografia compatíveis com polineuropatia desmielinizante, sem qualquer lesão cutânea ao exame de admissão. O raciocínio clínico inicial foi direcionado para o diagnóstico das polineuropatias desmielinizantes inflamatórias adquiridas como Polineuropatia Desmielinizante Inflamatória Crônica (CIDP) e suas variantes. No entanto, após anamnese e exame físico detalhados, chamou a atenção a ausência do componente atáxico e a presença predominante de alterações sensitivas de fibra fina, espessamento de nervo e importante fator epidemiológico para hanseníase, motivando a suspeita e a in-vestigação desta enfermidade por meio da biópsia de nervo que foi sugestiva de hanseníase. Após três meses, em novo exame do paciente para biopsiar áreas de anestesia para reforçar o diagnóstico, observou-se o surgimento de extensas lesões levemente hipocrômicas no tronco e membros inferiores, cuja biópsia definiu o diagnóstico de hanseníase.

ABSTRACT: Study: Case report. Importance: Worldwide over three million people are living with disabilities due to leprosy. Brazil is the second country with the highest number of new cases registered. The magnitude and high risk of disability make the disease a public health problem. The diagnosis of leprosy can be simple. However, in the absence of skin lesions and with many possibilities of neurological impairment, diagnosis can become a challenge. Comments: We report the case of a patient referred to the neurology service with a clinical history and electrophysiological tests compatible with demyelinating polyneuropathy, without any skin lesion at admission examination. The initial clinical research was directed to the diagnosis of acquired inflammatory demyelinating polyneuropathies such as Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)and its variants. However, after anamnesis and detailed physical examination, the absence of the ataxic component and the predominant presence of sensory alterations of fine fiber, nerve thickening and important epidemiological factor for leprosy,led to the suspicion and investigation of this disease by nerve biopsy that was suggestive of leprosy. After three months, in a new patient examination "to perform a biopsy in areas of anesthesia" to reinforce the diagnosis, there was the appearance of extensive slightly hypochromic lesions in the trunk and lower limbs, whose biopsy defined the diagnosis of leprosy.(AU)

ABSTRACT

Com grande distribuição mundial e incidência significativa, a toxoplamose é uma doença comum em mamíferos e pássaros, causada pelo protozoário Toxoplasma gondii. No homem, o parasitismo na fase proliferativa intracelular pode se apresentar sem sintomas, ou causar clínica transitória caracterizada por febre, fadiga e linfadenopatia. Por se tratar de patologia com sintomas inespecíficos e comuns a muitas outras, é fundamental a correta pesquisa de diagnósticos diferenciais, como citomegalovírus e Epstein-Barr. Relatamos o caso de um jovem e hígido, que desenvolveu pneumonia e, após confirmação sorológica para toxoplasmose e o tratamento adequado, apresentou melhora clínica.


With great worldwide distribution and significant incidence, toxoplamosis is a common disease in mammals and birds, caused by the protozoan Toxoplasma gondii. In humans, the parasitism in its intracellular proliferative phase may present no symptoms, or cause a transient condition characterized by fever, fatigue, and lymphadenopathy. Because it is a pathology with nonspecific symptoms that are common to many other conditions, it is fundamental to find the correct research of differential diagnoses, such as for Cytomegalovirus and Epstein Barr. We report a case of a young and healthy man who developed pneumonia and, after serological confirmation for toxoplasmosis and the appropriate treatment, presented clinical improvement

ABSTRACT

A gengivite tem se tornado a doença periodontal que apresenta maior prevalência na atualidade. Este trabalho tem como objetivo, avaliar a prevalência da gengivite associada ao biofilme em pacientes atendidos na Clínica Escola de Odontologia de um Centro Universitário no interior do Ceará, além de analisar, sexo, faixa etária, associação com alterações sistêmicas e o fumo. Desta forma, foi realizado um estudo epidemiológico de base de dados secundários, executado através de avaliação de prontuários de pacientes que foram atendidos no período de 2013 a 2018. Um total de 8.039 prontuários avaliados, apenas 2.821 (35%) atenderam aos critérios de inclusão. Diante dos dados (30%) foram identificados com saúde periodontal. Enquanto que a gengivite associada ao biofilme apresentou-se como sendo a alteração periodontal com maior prevalência em (74%) dos casos. O sexo feminino é dominante em (62%) dos pacientes. A faixa etária mais acometida foi de 30 a 44 anos. Em relação ao uso de tabaco, (78%) nunca fizeram uso. Por conseguinte, (86%) não apresentaram nenhum tipo de doença sistêmica. Conclui-se que mulheres normossistêmicas, não fumantes e acima de 30 anos de idade, apresentaram maior predisposição para o desenvolvimento de gengivite (AU)


Gingivitis has become the most prevalent periodontal disease now a days. The aim of this study is to evaluate the prevalence of gingivitis associated to biofilm in patients treated at the School of Dentistry Clinic of a University Center in Ceará, as well as to analyze gender, age, association with systemic changes and smoking. Thus, an epidemiological study of secondary database was performed, through the evaluation of medical records of patients who were attended from 2013 to 2018. A total of 8,039 medical records evaluated, only 2,821 (35%) met the inclusion criteria. Due to the data (30%) were identified with periodontal health. While gingivitis associated to biofilm was the most prevalent periodontal alteration in (74%) of the cases. Females are dominant in (62%) patients. The most affected age group was 30 to 44 years. Regarding tobacco use, (78%) never made use of it. Therefore, (86%) did not present any type of systemic disease. It was concluded that normosystemic women, non-smokers and over 30 years old, were more predisposed to the development of gingivitis. (AU)

ABSTRACT

Malaria is a disease of global tropical distribution, being endemic in more than 90 countries and responsible for about 212 million cases worldwide in 2016. To date, the strategies used to eradicate this disease have been ineffective, without specific preventive measures such as vaccines. Currently, the existing therapeutic arsenal is limited and has become ineffective against the expansion of artemisinin-resistant Plasmodium, demonstrating the need for studies that would allow the development of new compounds against this disease. In this context, we studied the volatile oil obtained from rhizomes of Cyperus articulatus (VOCA), a plant species commonly found in the Amazon region and popularly used as a therapeutic alternative for the treatment of malaria, in order to confirm its potential as an antimalarial agent by in vitro and in vivo assays. We cultured Plasmodium falciparum W2 (chloroquine-resistant) and 3D7 (chloroquine-sensitive) strains in erythrocytes and exposed them to VOCA at different concentrations in 96-well microplates. In vivo antimalarial activity was tested in BALB/c mice inoculated with approximately 106 erythrocytes infected with Plasmodium berghei. VOCA showed a high antimalarial potential against the two P. falciparum strains, with IC50 = 1.21 µg mL-1 for W2 and 2.30 µg mL-1 for 3D7. VOCA also significantly reduced the parasitemia and anemia induced by P. berghei in mice. Our results confirmed the antimalarial potential of the volatile oil of Cyperus articulatus. (AU)

ABSTRACT

Modelo do estudo: relato de caso Importância do problema: A tuberculose é um grave problema de saúde no nosso país, no entanto poucos profissionais sabem identificar as formas extrapulmonares da doença, que são responsáveis por 23,3% dos óbitos por tuberculose no Brasil. Das formas extra-pulmonares, apenas 1-2% representam formas cutâneas. É importante que o médico generalista conheça as formas cutâneas de tuberculose, uma vez que pode ser a única manifestação da doença. O seu diagnóstico é um desafio, pois os exames tradicionais têm menor sensibilidade e especificidade para a apresentação cutânea em relação à forma pulmonar. No entanto, novos exames vêm sendo implantados como o GeneXpert. Comentários: Relatamos um caso raro de tuberculose cutânea em paciente imunocompetente, com a manifestação de três formas clínicas simultaneamente ­ escrofuloderma, tubercúlide papulonecrótica e eritema indurado de Bazin. A ocorrência de duas formas simultâneas é descrita na literatura mas a ocorrência de três formas simultâneas é inédita. Essa manifestação atípica foi de difícil diagnóstico clínico por simular outras doenças e os exames tradicionais como o RX de tórax, baciloscopia e cultura não evidenciaram o diagnóstico. A identificação do Mycobacterium tuberculosis só foi possível por meio da pesquisa de PCR com o GeneXpert, que mostrou positividade no escarro pulmonar e no exsudato do escrofuloderma, possibilitando iniciar o tratamento precocemente. Este novo exame de alta sensibilidade e especificidade no diagnóstico da tuberculose pulmonar mostrou-se de grande utilidade no diagnóstico deste caso atípico de tuberculose cutânea onde os exames tradicionais não definiram o diagnóstico. (AU)


Study: Case Report Importance: Tuberculosis is a serious health problem in Brazil. Nevertheless, only few physicians know how to identify the non-pulmonary cases of this disease, which can represent up to 23,3% of deaths caused by tuberculosis in Brazil. Among the non-pulmonary cases, only 1-2% affect the skin. It is important for the general physician to understand the cutaneous presentations of tuberculosis, once it can be the only symptom that the patient presents. Diagnosing cutaneous tuberculosis is a challenge, because traditional laboratory tests have smaller sensitivity and specificity for the cutaneous form in contrast to pulmonary tuberculosis. However, implementation of new exams such as GeneXpert may come in hand. Comments: We report a rare case of cutaneous tuberculosis on an immunocompetent patient, with three different simultaneous presentations - scrofuloderma, papulonecrotic tuberculids and Bazin's indurated erythema. Occurrence of two simultaneous presentations has been reported, however, three simultaneous forms have not. Diagnosing this atypical manifestation was very hard because the clinical presentation often mimics other dermatological conditions, and traditional laboratory testing such as chest X-ray, bacilloscopy and culture did not evidence infection. Identification of Mycobacterium tuberculosis was only possible due to positive PCR testing through GeneXpert on pulmonary and scrofuloderma fluids, allowing rapid treatment initiation. This new high sensitivity and specificity exam proved to be of great value when diagnosing this atypical cutaneous tuberculosis case, in which diagnose was not possible through traditional laboratory testing.

ABSTRACT

The faveira bean (Parkia platycephala Benth.), belongs to the Fabaceae family, this species is recommended for afforestation and also has a forage potential. In addition, it has the potential of landscaping, the wood can be used for box-office, tables for internal divisions in small constructions, linings, confection of toys, as well as for firewood and charcoal. That way, the aim of this study was to evaluate the effect of different temperature and substrate on the germination of seeds of P. platycephala. The study was carried out at the laboratory for analysis of Seeds of the Department of Plant Science and Environmental Agricultural Sciences Center of the da Universidade Federal da Paraíba, in Areia - PB. Therefore, a completely randomized design and a 6 x 4 factorial arrangement were performed, consisting of the combinations of six temperatures (25, 30 and 35 °C constant and 20-30, 20-35 and 25-35 °C alternating) and four substrates (sand, coconut fiber, paper and vermiculite). To evaluate the effect of the treatments were performed germination test, first count and germination speed index, length of plants, root and aerial dry matter. The constant temperature of 35 °C provided better performance of seeds Parkia platycephala when using the sand as substrate.


A faveira (Parkia platycephala Benth.), pertence à família Fabaceae, é uma espécie recomendada para arborização e também possui potencial forrageiro. Além disso, tem potencial paisagístico, a madeira pode ser utilizada para caixotaria, tabuados para divisões internas em pequenas construções, forros, confecção de brinquedos, bem como para lenha e carvão. Dessa forma, o trabalho objetivou avaliar o efeito de diferentes temperaturas e substratos na germinação de sementes de P. platycephala. O mesmo foi realizado no Laboratório de Análise de Sementes, do Departamento de Fitotecnia e Ciências Ambientais do Centro de Ciências Agrárias da Universidade Federal da Paraíba, no município de Areia, PB. Portanto, realizou-se experimento em delineamento inteiramente ao acaso e arranjo fatorial 6 x 4, constituídos pelas combinações de seis temperaturas (25, 30 e 35 °C constantes e 20-30, 20-35 e 25-35 °C alternadas) e quatro substratos (areia, fibra de coco, papel e vermiculita). Para avaliação dos tratamentos realizou-se testes de germinação e vigor (primeira contagem e índice de velocidade de germinação, bem como o comprimento e massa seca das raízes e parte área).

ABSTRACT

The species Enterolobium contortisiliquum (Vell.) Morong., (Fabaceae) is widely distributed in Brazil, commonly found in the Atlantic Forest domain. Despite its importance for the ecosystems, studies based on storage of E. contortisiliquum seeds are scarce. The objective of this work was to evaluate the physiological quality of seeds of Enterolobium contortisiliquum stored in different packages, environments and storage periods. The seeds were obtained from ripe fruits at the beginning of the natural dispersion in seven selected trees, located in the municipality of Areia - Paraíba, between the months of November and December 2010 and then taken to the laboratory for analysis of Seeds of the Department of Plant Science and Environmental Agricultural Sciences Center of the Universidade Federal da Paraíba. A completely randomized design was used, with subdivided plots, being the major portion constituted by environments (lab, cold storage chamber, freezer and fridge), a sub-plot for the packages (kraft paper bag, cloth, aluminum, plastic (PP) and PET bottle) and the sub plot constituted by the storage periods (0, 30, 60, 90, 120, 150, 180, 210, 240 and 270 days). For the evaluation of physiological quality was determined by water content, percentage of emergence, length and dry weight of shoots and roots. The packing of seeds ofE. contortisiliquum can be made in polypropylene plastic bags (PP) and they can be stored under natural laboratory environment for 270 days with no decrease of seed vigor.


A espécie Enterolobium contortisiliquum (Vell.) Morong., (Fabaceae) tem ampla ocorrência noBrasil, especialmente no domínio de Mata Atlântica. Apesar de sua importância na dinâmica dos ecossistemas, os estudos sobre o armazenamento de suas sementes são escassos. Dessa forma, o objetivo do trabalho foi avaliar a qualidade fisiológica de sementes de Enterolobium contortisiliquum armazenadas em diferentes embalagens, ambientes e períodos de armazenamento. As sementes foram obtidas de frutos maduros no inicio da dispersão natural em sete árvores matrizes localizadas no município de Areia - PB, entre os meses de novembro e dezembro de 2010 e, em seguida, levados ao Laboratório de Análise de Sementes do Departamento de Fitotecnia e Ciências Ambientais do Centro de Ciências Agrárias da Universidade Federal da Paraíba. O delineamento foi inteiramente ao acaso em parcela subsubdividida, sendo a parcela principal constituída pelos ambientes (laboratório, câmara fria, freezer e geladeira), a subparcela pelas embalagens (papel kraft, pano, alumínio, plástico (PP) e garrafa PET) e a subsubparcela constituída pelos períodos de armazenamento (0, 30, 60, 90, 120, 150, 180, 210, 240 e 270 dias). Para avaliação da qualidade fisiológica determinou-se o teor de água, porcentagem de emergência, comprimento e massa seca de parte aérea e raízes. As sementes de E. contortisiliquumpodem ser acondicionadas em embalagem de saco de plástico de polipropileno (PP) e armazenadas em ambiente natural de laboratório durante 270 dias sem redução no vigor.

ABSTRACT

O sucesso da reabilitação de pacientes edêntulos requer uma adaptação funcional e psicológica. As preocupações dos pacientes estão relacionadas ao conforto, à função e à estética. A prótese total sobre implantes é uma alternativa para pacientes totalmente desdentados com rebordo ósseo, que não proporciona retenção e nem estabilidade para uma prótese total convencional. Próteses sobre implantes esteticamente favoráveis estão diretamente relacionadas com a condição dos tecidos moles e duros que as envolvem. A preservação dos tecidos mucogengivais ao redor de implantes dentários instalados na maxila anterior propicia um sorriso harmonioso, com uma estética bastante agradável. O tratamento de reparação dentária deve ter início com a construção de próteses diagnósticas, onde o profissional pode prever o resultado final. Este artigo tem como objetivo mostrar a importância da gengiva artificial de porcelana em pacientes que tiveram reabsorção óssea, perda da DVO e perda de tecido gengival, utilizando o ODEF (Oral Design para Estética e Função Oclusal) no diagnóstico estético e oclusal como planejamento reverso.


The successful rehabilitation of edentulous patients requires a functional and psychological adaptation. Patient concerns are related to comfort, function and aesthetics. Total prosthesis on implants is an alternative for fully edentulous patients with a bone ridge that provides no retention and no stability for a conventional total prosthesis. Prostheses on aesthetically favorable implants are directly related to the condition of soft and hard tissues that surround them. The preservation of the mucogingival tissues around dental implants installed in the anterior maxilla provides a harmonious smile, with a pleasant aesthetic. The dental repair treatment should begin with diagnostic prostheses manufacturing, with which the professional can predict the final result. This article aims to show the importance of porcelain artificial gingiva in patients who have had bone resorption, loss of VDO and loss of gingival tissue, using ODEF (Oral Design for Aesthetics and Occlusal Function) in aesthetic and occlusal diagnosis as a reverse planning.

ABSTRACT

ABSTRACT: Caesalpinia pulcherrima is a Fabaceae family species from Central America, which has a small size and is widely used as a living fence in the urban afforestation for streets, parks, and gardens. Based on this importance, the aim of this research was to study the influence of light and temperature on the germination of C. pulcherrima seeds. The study was carried out at the Laboratory of Seed Analysis of the Center of Agricultural Sciences of the Universidade Federal da Paraíba, Areia, PB, Brazil. The experimental design was completely randomized, comprising a 3x5 (three temperatures and five light regimes) factorial scheme with four replicates containing 25 seeds each. Germination and vigor of seeds were evaluated under temperatures of 25°C and 30ºC constant and 20-30ºC alternated in different light regimes: white, green, red-distant, red, and absence of light. Variables analyzed were: germination, first germination count, germination speed index, root length, shoot length, and the ratio of dry mass of root/shoot of the seedlings. Seeds of C. pulcherrima germinate in the presence and absence of light, being a neutral photoblastic. Recommendation to test the vigor of these seeds is the temperature of 30°C in the white light regime.

A pesquisa foi conduzida no Laboratório de Análise de Sementes, do Centro de Ciências Agrárias da Universidade Federal da Paraíba, em Areia, PB, Brasil. O experimento foi conduzido em um esquema fatorial 3x5 (três temperaturas e cinco regimes de luz) com quatro repetições, contendo 25 sementes para cada tratamento. Avaliou-se a germinação e vigor das sementes sob temperaturas de 25°C e 30ºC constantes e 20-30ºC alternada em diferentes regimes de luz: branca, verde, vermelha-distante, vermelha, e ausência de luz. As variáveis analisadas foram: germinação, primeira contagem de germinação, índice de velocidade de germinação, comprimento de raiz/parte aérea e massa seca de raiz/parte área de plântulas. As sementes de C. pulcherrima germinam na presença e ausência de luz, sendo um fotoblástico neutro. A recomendação para testar o vigor dessas sementes é a temperatura de 30°C no regime de luz branca.

ABSTRACT

ABSTRACT This paper reports the first study of the variation of the chemical composition and abundance of the essential oil of Croton heliotropiifolius, in four seasons, and the evaluation of its antibacterial activity. Essential oil obtained from leaves of C. heliotropiifolius were analyzed by GC/MS and evaluated against eight bacteria strains by broth microdilution method. The chemical constituents identified were the same in all samples, but with different proportions. The total percentages identified were 96.58% in summer, 92.08% in autumn, 98.44% in winter and 90.78% in spring. The majors constituents are β-caryophyllene, bicyclogermacrene, germacrene-D, limonene and 1,8-cineole. β-Caryophyllene was the major compound in all samples. The results of the antibacterial evaluations showed weak to moderate activity against the analyzed strains. In all analyzes was observed that essential oil sample collected in summer stands out from the others, displaying stronger activity against Gram-positive as Gram-negative bacteria.

ABSTRACT

Abstract Introduction Optical microscope images can be useful to evaluate nebulizers considering the size of droplets produced by these devices. From this perspective, the proposed method was compared to the classic concept of Mass Median Aerodynamic Diameter (MMAD) for the ideal droplet size between 0.5-5.5 µm. Methods We tested a sample of five home nebulizers sold on the Brazilian market. A high-speed camera coupled to a microscope obtained images of the droplets during the nebulization process, which allowed us to characterize the diameter of the aero-dispersed droplets. The Count Median Aerodynamic Diameter (CMAD) was used as measurement parameter. Results The images obtained during the nebulization process with the five different nebulizers provided data to determine the frequency distribution of the aero-dispersed droplet population. Successive images were obtained in the range of 2.0s to evaluate the dynamic behavior of the droplets. The generated data also allowed the elaboration of histograms emphasizing the ideal diameter range of droplets between 0.5 and 5.5 μm. Conclusion The Direct Laminar Incidence (DLI) model using digital image processing technique allowed the characterization of respirable particles. This model proposes the creation of a range of optimum absorption of the droplets by the respiratory tract. Although there is a technical limitation in the direct acquisition of images due to the depth of focus, presenting an error of 9.3%, the described method provides consistent results when compared to other droplets characterization techniques. Thus, the authors believe that Direct Laminar Incidence (DLI) is a viable method to assess the performance of nebulizers despite the requirement of adjustments and possible improvements required to minimize measurement errors.

ABSTRACT

INTRODUCTION: The study of the nutritional status of the elderly merits attention, since there is no consensus regarding the criteria for the evaluation of the Body Mass Index (BMI) of this population. OBJECTIVE: The evaluation of the nutritional status of elderly women practicing regular physical exercise, as well as the comparison of the World Health Organization (WHO) and the Lipschitz criteria for the identification of health risks in order to examine their agreement. METHOD: A descriptive cross-sectional study was conducted with the participation of 76 elderly women taking part in physical exercise groups in Petrolina-PE. The nutritional status was obtained by the calculation of BMI, according to the WHO and Lipschitz criteria. The Variance analysis (ANOVA) was used to compare the variables, followed by Tukey's post hoc. The Kappa statistic established an agreement between the two BMI criteria and the Spearman coefficient determined a correlation between BMI and waist circumference (WC). RESULTS: Elderly women aged 60-79 years old were classified as being overweight by WHO and eutrophic by Lipschitz. Participants 80-89 years old demonstrated eutrophy, according to the Lipschitz criteria, while the WHO criteria diverged for this group between thinness and eutrophy. There was weak agreement between both the criteria, Kappa (0.232, p = 0.002) and a strong correlation between BMI and WC (r = 0.722, p <0.001). CONCLUSION: A divergence between the WHO and Lipschitz criteria was found. The WHO criteria proved to be more sensitive for identifying overweight and obesity, while the Lipschitz criteria were more sensitive for identifying normal weight and malnutrition. The WC measure was more accurate for detecting health risks, especially in elderly eutrophic women.


INTRODUÇÃO: O estudo do estado nutricional de idosos merece atenção, visto que não existe um consenso sobre os critérios ideias à avaliação do Índice de Massa Corporal (IMC) dessa população. OBJETIVO: Avaliar o estado nutricional de idosas praticantes regulares de exercícios físicos, bem como comparar os critérios da Organização Mundial de Saúde (OMS) e de Lipschitz à identificação do risco de saúde e examinar sua concordância. MÉTODO: Estudo transversal analítico descritivo, realizado com 76 idosas integrantes de grupos de exercícios físicos, em Petrolina-PE. O estado nutricional foi obtido pelo cálculo do IMC, conforme os critérios da OMS e Lipschitz. Utilizou-se a análise de Variância (ANOVA) para comparação das variáveis, seguida pelo post hoc de Tukey. A estatística de Kappa estabeleceu a concordância entre os critérios do IMC, o coeficiente de Spearman determinou a correlação entre o IMC e a medida da circunferência abdominal (CA). RESULTADOS: Idosas entre 60-79 anos foram classificadas, sobretudo, com excesso de peso pela OMS e eutróficas por Lipschitz. Octogenárias demonstraram eutrofia segundo o critério de Lipschitz, a OMS divergiu para este grupo entre magreza e eutrofia. Verificou-se concordância fraca entre ambos os critérios, Kappa (0,232, p=0,002) e forte correlação entre o IMC e a CA (r=0,722, p<0,001). CONCLUSÃO: Existiu divergência entre os critérios da OMS e Lipschitz. A OMS se mostrou mais sensíveis para identificar sobrepeso e obesidade e Lipschitz o peso normal e a desnutrição. A medida da CA foi mais competente para detectar o risco de saúde, principalmente, em idosas eutróficas.
