Ficha de Observação/Avaliação Motora: Ficha para verificação da qualidade de jogo dos alunos do 3º ciclo do Ensino Básico, nos Jogos Desportivos Colectivos

The present work consisted on the design of a motor performance observational sheet that could also be used for motor evaluation. For this purpose, we analyzed the common characteristics of group sports, with the intention of obtaining a distinction between the two final levels (good or weak). We also used all the basic theoretical assumptions inherent to the construction of motor performance tests, as well as the programme for Physical Education proposed by the Education Ministry for the school year of 2004/2005. This work has emerging relevance mainly due to the lack of observational instruments on the motor performance, domain of group sports with territorial invasion. We therefore, attempted to create an observational sheet as valid, objective and reliable as possible, in order to evaluate students of the third grade of basic education. This assessment was made independently of student age or gender so that the success criterion could be adapted to the abilities that are expected to be present in these students. Prior to the use of this observational sheet, the proper application conditions should be present, as well as its application protocol should be of the subject’s knowledge. When used along with video aid this sheet becomes an extraordinarily simple and fast instrument to work with, being also wide enough to include several types of group sports

Antioxidant activity and cytotoxicity of solubilized C60 and its conjugates with butylated hydroxytoluene

It has been described that fullerenes (C60) present interesting properties with potential application in clinical conditions related to oxidative stress. One of the most prominent features of fullerenes is the ability to quench free radicals. However, because of its poor solubility, this has been studied mostly in organic solutions, while the antioxidant activity and cytotoxicity of fullerenes and their derivates in aqueous medium is not well characterized. The antioxidant capacity of synthesised C60-conjugates has been investigated and its was higher comparing to C60 isolated. The aim of this study was to assess the viability of C60-conjugates by determining its antioxidant activity and cytotoxicity in bio-relevant media

In vitro cytocompatibility evaluation of poly(DL-lactic acid) scaffolds loaded with minocycline and voriconazole addressing osteomyelitis

Osteomyelitis or bone infection is an acute or chronic inflammatory process involving the bone and its structures, secondary to infection with pyogenic organisms, such as bacteria and fungi. Considering the associated high patient economic burden, morbidity, and mortality, it is essential to develop novel strategies for osteomyelitis management. Porous scaffolds based on biomaterials may locally deliver high concentrations of antibiotics, an effective strategy in eradicating bone infection. When incorporating bioactive bioglasses and bioresorbable polymers like poly(DL-lactic acid) (PDLLA), these structures exhibit biosafety, biodegradability, and the expected global structure to promote cell expansion and cell differentiation, being critical to consider and evaluate their biocompatibility compliance. As the encapsulation of more than one active pharmaceutical ingredient is an attractive approach, the present study focuses on the cytocompatibility evaluation of an innovative system based on the dual delivery of two antimicrobials, an antibiotic that enhances bone formation, minocycline (MH), and an antifungal agent with a broad spectrum of activity, voriconazole (VCZ), aiming bone infection therapeutics. Scaffolds were prepared by solvent casting/particulate leaching techniques and functionalized with bioglass. The scaffolds produced were adsorbed with 0.5 or 0.1 mg/mL of minocycline and also with 0.1 mg/mL of voriconazole. To test the bio-functionality and the biological safety of scaffolds, in vitro cell assays were achieved employing the MG-63 cell line (ATCC® CRL-1427TM human osteoblast cell line). The AlamarBlue® assay was used to measure cell proliferation in the scaffold. As osteoblast differentiation markers, the following were determined: alkaline phosphatase activity and mineralization using Alizarin red assay, an indicator of in vitro bone formation. All scaffolds sustained the proliferation of metabolically active cells, nonetheless, scaffolds adsorbed with the highest concentration of MH (0.5 mg/mL) presented a significant (p<0.05) cytotoxic effect. Matrix maturation assays supported early osteoblasts differentiation and the osteoinductive role of minocycline described in the literature was also highlighted. Matrix mineralization analysis showed the highest value associated with scaffolds with both antimicrobials adsorbed. Once the described scaffolds enhanced osteoblasts' differentiation, and matrix mineralization and evidenced no cytotoxic effects, they come to light as an auspicious alternative for local antimicrobial therapy addressing osteomyelitis prevention and therapeutics.info:eu-repo/semantics/publishedVersio

Nationwide consensus on quality indicators to assess glaucoma care: A modified Delphi approach

Purpose Performance assessments are essential to tracking and improving quality in health care systems. Key aspects of the care process that act as indicators must be measured in order to gain an in-depth understanding of a care unit's operation. Without standardized quality indicators (QIs), it is difficult to characterize and compare the abilities of institutions to achieve excellence. The aim of this study is to reach a consensus among glaucoma specialists concerning the development of a set of QIs to assess the performance of glaucoma care units. Methods A two-round Delphi technique was performed among glaucoma specialists in Portugal, using a 7-point Likert scale. Fifty-three initial statements (comprising process, structure, and outcome indicators) were evaluated and participants had to agree on which ones would be part of the final set of QIs. Results By the end of both rounds, 28 glaucoma specialists reached consensus on 30/53 (57%) statements, including 19 (63%) process indicators (mainly relating to the proper implementation of complementary exams and the setting of follow-up intervals), 6 (20%) structure indicators, and 5 (17%) outcome indicators. Of the indicators that were part of the final list, functional and structural aspects of glaucoma progression and the availability of surgical/laser procedures were the most prevalent. Conclusions A set of 30 QIs for measuring the performance of glaucoma units was developed using a consensus methodology involving experts in the field. Their use as measurement standards would provide important information about unit operations and allow further implementation of quality improvements

Insatisfação relativa à MC: preço elevado da assistência médica privada; alto custo dos medicamentos; precariedade da assistência prestada pelos serviços públicos. Crenças positivas sobre MCA: tão eficazes como a MC; se correctamente utilizadas, não ocasionam efeitos colaterais prejudiciais; mais compatíveis com valores pessoais e filosofias religiosas do que MC. Utilização das MCA: mais utilizadas (homeopatia e fitoterapia); tratamento e controlo de doenças crónicas. Objectivo do estudo: caracterizar as crenças sobre homeopatia e fitoterapia e os comportamentos de consumo dos estudantes da ESTeSL, enquanto consumidores e futuros profissionais de saúde

Experimental assessment of Textile Reinforced Sprayed Mortar strengthening system for brickwork wallettes

This work explores the feasibility of strengthening masonry with Textile Reinforced Mortar (TRM) by projecting it to save application time. Nineteen tests on masonry samples strengthened with TRM have been carried out to assess this new application method. Different mortars and fibre grids were considered for studying their influence and applicability with this new technique. Three points bending tests have been performed on the specimens to compare the flexural strength between cases with manually applied mortar (TRM) and sprayed application (TRSM) of the mortar layer. It was noticed that the strengthening mortar has a significant influence on the failure mode. Results show a remarkable (between 2 and 6 times more) productivity increase when using TRSM and a load-bearing capacity rise for the cases with larger grid spacing and projectable mortar when using TRSM instead of TRM. Greater ductility values were also observed for the TRSM cases in comparison with the analogue TRM cases (same grid and mortar). (C) 2013 Elsevier Ltd.

Erros de distribuição em dose unitária: tipos e causas

Os erros de medicação são um problema de saúde pública com uma repercussão económica importante, afectando a qualidade de vida dos utentes e os custos em saúde. Ao nível da farmácia hospitalar, “que tem como principal função a dispensa dos medicamentos aos doentes de acordo com a prescrição médica, nas quantidades e especificações solicitadas, de forma segura e no prazo requerido, promovendo o uso seguro e racional do medicamento,” o erro de distribuição é definido como a discrepância entre a ordem prescrita pelo médico e o atendimento dessa ordem, podendo gerar oportunidades de erros de administração. Os erros classificam-se em função da etapa do circuito do medicamento em que ocorrem: prescrição, distribuição e administração. A distribuição de medicamentos em sistema de dose unitária (DMDU) está descrita como imperativo para aumentar a segurança no circuito do medicamento, prevendo uma distribuição diária de medicamentos, em dose individual unitária, para um período de 24 horas. Sempre que possível, a DMDU deverá apoiar-se em equipamentos semi-automáticos, para redução dos erros. Sendo a qualidade e segurança uma preocupação crescente e uma prioridade dos sistemas de saúde, os profissionais de saúde devem intervir activamente na melhoria dos sistemas de utilização dos medicamentos para garantir a segurança do doente. Consequentemente, vários estudos têm sido desenvolvidos para verificar os tipos de erros mais frequentes em farmácia hospitalar. Objectivo do estudo: identificar os principais erros de distribuição em dose unitária descritos na literatura nos últimos 5 anos e as suas causas, através de uma revisão sistemática
