CONTRIBUIÇÃO AO ESTUDO QUÍMICO DE FOLHAS DE Lippia thymoides

O gênero Lippia (Verbenaceae) destaca-se pela sua composição química rica emcompostos fenólicos como os flavonoides, os quais possuem atividade antioxidante(FURANI, 2010; SUDHA; SRINIVASA, 2014). A maioria das espécies de Lippia sãoaromáticas, assim os estudos relacionados à fitoquímica desse gênero sãoprincipalmente dedicados à composição química dos óleos essenciais (CATALAN;LAMPASONA, 2002)

The influence of previous sport experiences in transfer of behaviour patterns among team sports

The present study aimed to examine how players' positional data can be used to assess the transfer of behaviour patterns among team sports (basketball, football and rugby) in early specialized and diversified sport careers. Thirty-four college students were divided into early specialization and early diversification groups, according to information provided by a questionnaire designed to obtain detailed information about their sports career. In-game derived variables were calculated based on players' positioning data, collected by GPS and processed with non-linear techniques (approximate entropy). For each positional variable (distance to both team and opponent team centroid and distance to target and opponent target) a top-10 ranking was computed based on approximate entropy values in basketball, football and rugby game performance. The results suggested that students belonging to the early diversification group are over-represented (top-10) in all positional variables regardless of sport. This trend, especially in football and rugby, confirms that it is possible that transfer of behavior patterns occurs more significantly in early diversified approach.El presente estudio tuvo como objetivo examinar cómo se pueden utilizar los datos posicionales de los jugadores para evaluar la transferencia de patrones de comportamiento entre los deportes de equipo (baloncesto, fútbol y rugby) en las carreras deportivas de especialización ó diversificación temprana. Treinta y cuatro estudiantes universitarios fueron divididos en grupos de especialización temprana ó de diversificación temprana, de acuerdo a la información proporcionada por un cuestionario diseñado para obtener información detallada acerca de su carrera deportiva. Las variables de la situación de juego, fueron calculadas en función de los datos de posicionamiento de los jugadores, obtenidos por GPS y procesados con técnicas no lineales (entropía aproximada). Para cada variable posicional (distancia de la propia equipo a su centro, y la distancia al centro del equipo contrario y la meta oponente) se calculó un ranking top-10 con en base a los valores de entropía aproximadas en el juego del baloncesto, fútbol y rugby. Los resultados sugieren que los estudiantes pertenecientes al grupo de la diversificación temprana son más representado (top-10) en todas las variables posicionales, independientemente del deporte. Esta tendencia, sobre todo en el fútbol y el rugby, confirma que es posible que la transferencia de patrones de comportamiento se produce más significativamente cuando la iniciación deportiva es direccionada a una diversificación temprana

the incomplete process of an action research in the hospital

Health professionals are at high risk for developing burnout symptoms. Directed at reducing the organizational variables affecting professionals’ burnout, an action research was developed in a specific sector of a large hospital, with 59 doctors, 66 nurses, and 42 ancilliary professionals. Researchers conducted 11 interviews, one focus group, and 20 h of in loco observation. Professionals report demotivation and the need to address the emotional part of their job. Nonetheless, the hierarchy blocked the proposed intervention possibilities. Organizational factors are unequivocally relevant, particularly in complex settings with emotionally charged interactions, and the direct hierarchy is pivotal for facilitating organizational change.publishersversionpublishe

Caso clínico dermatológico

Congenital cutaneous candidiasis is a rare disease acquired in utero via ascending Candida infection. Skin involvement is diffuse and often appears in the first six days of life. Diagnosis can be confirmed by microscopic examination and cutaneous lesion culture. Empiric therapy with systemic antifungal should be promptly started at the time of cutaneous manifestations, specially in preterm infants, to prevent dissemination and decrease mortality risk.info:eu-repo/semantics/publishedVersio

Changes in choroidal thickness and retinal activity with a myopia control contact lens

Purpose: The axial elongation in myopia is associated with some structural and functional retinal changes. The purpose of this study was to investigate the effect of a contact lens (CL) intended for myopia control on the choroidal thickness (ChT) and the retinal electrical response. Methods: Ten myopic eyes (10 subjects, 18–35 years of age) with spherical equivalents from −0.75 to −6.00 diopters (D) were enrolled. The ChT at different eccentricities (3 mm temporal, 1.5 mm temporal, sub-foveal ChT, 1.5 mm nasal, and 3 mm nasal), the photopic 3.0 b-wave of ffERG and the PERG were recorded and compared with two material-matched contact lenses following 30 min of wear: a single-vision CL (SV) and a radial power gradient CL with +1.50 D addition (PG). Results: Compared with the SV, the PG increased the ChT at all eccentricities, with statistically significant differences at 3.0 mm temporal (10.30 ± 11.51 µm, p = 0.020), in sub-foveal ChT (17.00 ± 20.01 µm, p = 0.025), and at 1.5 mm nasal (10.70 ± 14.50 µm, p = 0.044). The PG decreased significantly the SV amplitude of the ffERG photopic b-wave (11.80 (30.55) µV, p = 0.047), N35-P50 (0.90 (0.96) µV, p = 0.017), and P50-N95 (0.46 (2.50) µV, p = 0.047). The amplitude of the a-wave was negatively correlated with the ChT at 3.0T (r = −0.606, p = 0.038) and 1.5T (r = −0.748, p = 0.013), and the amplitude of the b-wave showed a negative correlation with the ChT at 1.5T (r = −0.693, p = 0.026). Conclusions: The PG increased the ChT in a similar magnitude observed in previous studies. These CLs attenuated the amplitude of the retinal response, possibly due to the combined effect of the induced peripheral defocus high-order aberrations impacting the central retinal image. The decrease in the response of bipolar and ganglion cells suggests a potential retrograde feedback signaling effect from the inner to outer retinal layers observed in previous studies.This work was funded by the Portuguese Foundation for Science and Technology (FCT) in the framework of projects PTDC/FIS-OPT/0677/2014, the FCT Strategic Funding UID/FIS/04650/2013, FCT-SFRH/BPD/92365/2013 and SFRH/BD/136684/2018

Estudo das alterações imunofenotípicas de populações linfocitárias em doentes com artrite reumatóide

A Artrite Reumatóide (AR) é uma doença auto-imune que devido às suas características tornam por si só os indivíduos afectados susceptíveis a infecções; imunocomprometimento que por vezes ainda é agravado por terapêuticas imunomodulatórias usadas para o seu tratamento. Este estudo tem como objectivo analisar, as populações/sub-populações de linfócitos conjuntamente com a análise das imunoglobulinas G e M, apresentando como factores discriminatórios, a idade, o sexo e a presença de terapêutica imunomodulatória, nos doentes com AR. Os resultados sugerem uma depleção significativa dos linfócitos B e um aumento dos T, os quais dão indícios para um aumento da susceptibilidade a infecções.Rheumatoid arthritis (RA) is an autoimmune disease that due to their characteristics make itself affected individuals susceptible to infections, immunosuppression which sometimes is still aggravated by immunomodulatory therapies used to treat it. This study has as objective analyze the populations/sub-populations of lymphocytes together with the analysis of immunoglobulins G and M, presenting as discriminatory factors age, sex and the presence of immunomodulatory therapy in patients with RA. The results suggest a significant depletion of B cells and an increase in T, which give clues to an increased susceptibility to infections

Correlação dos achados clínicos com os parâmetros funcionais em idosos portadores de asma

AbstractIntroduction: Advanced age is a risk factor for a blunted perception of the symptoms, severity and mortality of asthma. There are only a few studies in the literature on the relationship between respiratory symptoms and pulmonary function in elderly asthmatics.Aims: To evaluate the divergence between clinical and functional classification of asthma in the elderly and to characterise subgroups of patients at greater risk of clinico-functional divergence.Material and methods: A cross-sectional study evaluating 41 elderly asthmatics (60years old or over; 33 female; mean age 68.2years old). Data on age, gender, educational level, smoking, time since diagnosis of the disease and weight were obtained. Clinical classification, peak expiratory flow measurement and spirometry were performed.Results: We found that forced expiratory volume in one second (FEV1) correlated positively with the other functional parameters, and FEV1 correlated negatively with time since diagnosis of the disease. The percentage of clinico-functional divergence was 73.2%. Female patients and those with lower levels of schooling had an 8.6 and 9.3 risk of clinico-functional divergence respectively.Conclusion: The great clinico-functional divergence in elderly asthmatics shows the need to establish functional measurements as markers of asthma severity.Rev Port Pneumol 2009; XV (6): 1029-104

O perfil sociodemográfico da população em situação de rua no Estado de Santa Catarina e na Cidade de Florianópolis versus as estratégias e ações para o seu enfrentamento

The aim was to describe and analyze the socio-demographic profile of the homeless population registered in the Unified Registry of the Unified Health System in the State of Santa Catarina and in the city of Florianópolis in the period from 2014 to 2019 versus the implemented health strategies and actions aimed at to that population. This is a documentary, descriptive and retrospective study, with a quantitative approach, which analyzes the number of homeless people registered in the Unified Registry of the Unified Health System, in the State of Santa Catarina and in the capital, Florianópolis between the years of 2014 and 2019. The number of homeless people in the State of Santa Catarina and in the city of Florianópolis in the period from 2014 to 2019 showed an increasing trend. The results obtained with the study allow us to reflect that, despite the expansion of inclusive policies aimed at social issues involving the homeless population, in practice, there is still a need for governmental and non-governmental investments that can reduce urban violence and improve the living conditions of this population, including ease of satisfactory health care.Objetivou-se descrever e analisar o perfil sócio demográfico da população em situação de rua cadastrada no Cadastro Único do Sistema Único de Saúde no Estado de Santa Catarina e na cidade de Florianópolis no período de 2014 a 2019 versus as estratégias e ações de saúde implementadas destinadas a essa população. Trata-se de uma pesquisa documental, descritiva e retrospectiva, com abordagem quantitativa, que analisa o número de pessoas em situação de rua cadastrada no Cadastro Único do Sistema Único de Saúde, no Estado de Santa Catarina e na capital, Florianópolis entre os anos de 2014 e 2019. O número de pessoas da população em situação de rua no Estado de Santa Catarina e na cidade de Florianópolis no período de 2014 a 2019 apresentaram tendência crescente. Os resultados obtidos com estudo permitem refletir que, apesar da expansão de políticas inclusivas voltadas para as questões sociais que envolvem a população em situação de rua, na prática, ainda se observa a necessidade de investimentos governamentais e não governamentais que possam reduzir a violência urbana e melhorar as condições de vida desta população, incluindo a facilidade ao atendimento satisfatório a saúde
