Pediatric rehabilitation: social support and stress in cases of cerebral palsy / Reabilitação pediátrica: suporte social e estresse em casos de paralisia cerebral / Rehabilitación pediátrica: apoyo social y estrés en casos de parálisis cerebral

In pediatric rehabilitation, cerebral palsy constitutes one of the most diagnosed clinical conditions, however, further research is still necessary to improve care quality in the Brazilian context. Therefore, the present study aimed to: characterize, evaluate, and correlate social support and stress in family caregivers; and compare two care modalities (individual and group) of a rehabilitation program. In Study 1, 22 family members received individual and group care. In Study 2, 29 family members received only individual care. The instruments used were Sociodemographic Questionnaire, Social Support Perception Scale, Parental Stress Scale, Question about the Source of Social Support, and Case Reports. Researchers found no differences between the participants in Studies 1 and 2. The analysis of the entire sample revealed low-stress levels. Limited sources of support were observed, with family support being predominant. It was possible to identify a negative correlation between social support and stress.

Em reabilitação pediátrica, a paralisia cerebral é uma das condições clínicas mais diagnosticadas, mas ainda são necessárias pesquisas para aprimorar a qualidade assistencial no contexto brasileiro. Diante disso, a presente investigação teve como objetivos: caracterizar, avaliar e correlacionar suporte social e estresse de familiares cuidadores; e comparar duas modalidades de atendimento (individual e grupal) em um programa de reabilitação. No Estudo 1, 22 familiares receberam atendimentos individuais e grupais. No Estudo 2, 29 familiares frequentaram somente atendimentos individuais. Adotaram-se como instrumentos: o Questionário Sociodemográfico, a Escala de Percepção do Suporte Social, a Escala de Stress Parental, a Questão sobre Fonte de Suporte e os Registros de Casos. Não se constatou diferença entre participantes do Estudo 1 e do Estudo 2. A análise da totalidade amostral revelou baixo nível de estresse. Notou-se limitação das fontes de suporte, havendo predomínio do suporte familiar. Foi possível identificar correlação negativa entre suporte social e estresse

Assessment of coronal leakage of a new temporary light-curing filling material in endodontically treated teeth.

Introduction: The aim of this study was to evaluate the sealing ability of a new temporary filling material X‑Temp LC (DFL, São Paulo, SP, Brazil) compared with that obtained for Coltosol (Vigodent, Rio de Janeiro, RJ, Brazil) and Vitro Fill (DFL, Rio de Janeiro, RJ, Brazil), using a dye penetration test. Methods: Standard endodontic access cavities were prepared in 75 human premolars. The teeth were divided into five groups (n = 15 for each group), including a positive (no sealing of access cavity) and a negative control (Filtek Z350 XT, 3M, São Paulo, SP, Brazil). In the experimental groups, the access cavities were sealed with one of the three tested materials. After that, the teeth were immersed in 10% Indian ink for 14 days. The teeth were then rinsed, dried, sectioned in bucco‑lingual direction and evaluated under a stereomicroscope using scores for dye penetration. Data were analyzed using Kruskall‑Wallis and Student‑Newman‑Keuls tests (α =0.05). Results: Positive control sections exhibited complete dye penetration and negative control had no specimen showing marginal leakage. X‑Temp LC and Coltosol showed similar results, with no statistical difference between them. Vitro Fill exhibited the highest dye penetration among the experimental groups. Conclusion: The results of this in vitro study suggest that all temporary restorative materials exhibit some degree of marginal leakage. X‑Temp LC and Coltosol, however seal better than Vitro Fill glass ionomer cement.

Biological activities of the sulfated polysaccharide from the vascular plant Halodule wrightii

A sulfated polysaccharide (SPSG) was successfully isolated from seagrass Halodule wrightii Asch., Cymodoceaceae, and its antioxidant and anticoagulant activities were investigated. The data presented here showed that the SPSG is a 11 kDa sulfated heterogalactan with a sulfatation degree of 20.63 percent and it also contains glucose and xylose. SPSG antioxidant activities were evaluated using several in vitro assays and the anticoagulant activity was evaluated by aPTT and PT tests. These assays suggested that the SPSG possessed remarkable antioxidant properties in different in vitro assays and an outstanding anticoagulant activity 2.5-fold higher than that of heparin Clexane® in the aPTT test. This data represents the first reported on the sulfated polysaccharide biological activities from seagrass. These results indicate that SPSG can be considered in the future as a drug utilized in treating diseases from these systems.
