  • Barriers to access prenatal screening: integrative review
    Publication . Carvalho, Elisabete; Göttems, Leila; Monteiro, Sandra; Guilhem, Dirce; Ribeiro, Laiane
    Introduction: Prenatal monitoring is essential to reducing maternal and neonatal morbidity and mortality rates. However, organisational barriers may hamper access to the actions and services carrying on with the fragmentation and quality of care. Objectives: To analyse in the Brazilian scientific production the access barriers to performing screenings during prenatal monitoring. Method: Integrative review of publications searched in the bibliographic databases of Latin American and Caribbean Center on Health Sciences Information (LILACS), Nursing Database (BDENF), and Medical Literature Analysis and Retrieval System Online (MEDLINE), published in Portuguese, English, and Spanish from 2005 to 2015. Results: Of 708 articles searched, 15 met the inclusion criteria. The studies were systematised and led to four categories for analysis: (1) Sluggishness in the process of exam scheduling, sample collection, and releasing of results; (2) Insufficient quotas for the primary care screenings; (3) Lack of resources of the pregnant women; and (4) Adequacy of screenings related to the early onset of prenatal care. Conclusion: The access barriers to screenings in the prenatal monitoring are mainly related to the scant health resources devoted to primary care; sluggishness in the process of scheduling and running of tests; and to the lack of resources of the pregnant woman, who cannot afford the costs of examinations not covered by the public health system. The publications also highlighted the positive aspects for the pregnant women who had an early onset of prenatal care.

  • Formulation and Characterization of a Composite Coating Formulation Based on Acrylic Foam and Cork Granules
    Publication . Monteiro, Sandra; Ferreira, Nuno; Paiva, Diana; Silva, Susana P.; Martins, Jorge; Carvalho, Luisa; Magalhães, Fernão D.
    Cork, the bark of Quercus suber L., in addition to presenting several notable physicalmechanical properties, possesses a distinctive look and feel that make it attractive for interior surfaces, such as in furniture, wall paneling, or flooring. This work envisaged the development of a coating based on cork granules, a subproduct from the wine stopper industry, capable of creating a smooth surface similar to natural cork. In order to avoid the high rugosity that characterizes surfaces coated with paints that incorporate cork granules, a new solution was developed, based on a foamed acrylic binder, applied by knife coating. The foam formulation was successfully optimized, using appropriate additives and resorting to mechanical agitation to promote the generation of air bubbles. The addition of cork granules did not hinder foam stability, and the final coating displayed the intended visual and sensory characteristics. Dynamic Mechanical Analysis was performed on the pristine acrylic foam and on the composite foam showed a stiffening effect associated with the presence of cork granules, and a thermal transition centered at around −10 ◦C, associated with the acrylic binder’s glass transition. The surface has hardness slightly lower than cork, depending on the amount of particles incorporated. Pull-off testing consistently resulted in substrate failure, indicating that the coating’s cohesion and adhesion are excellent. The developed coating showed to have the intended functionality while being easily applicable on flat panel surfaces. The fact that a foam is used as a binder system allows for a smooth and soft surface, having excellent opacity with minimal usage of cork.
