Background: Integration between organizational units to achieve common goals has been of interest to health systems because of the potential to improve patient-centered care. However, the means by which integrative practices actually influence patient-centered care remain unclear. Whereas many studies claim a positive association between implementation of integrative practices and patient-centered care, others raise concerns that integrative practices may not necessarily improve patient-centered care. Purpose: The aim of this studywas to explore themechanismbywhich integrative practices influence patient-centered care and to suggest a systematic approach for effective integration. Approach: We conducted a qualitative study comparing diabetes and mental health services through focus groups with 60 staff members from one health maintenance organization.We developed quantitative indicators to support the suggested model. Findings: We identified a five-category framework of integrative practices that each directly and distinctively influences patient-centered care.Moreover, our findings suggest that integrative practices influence patient-centered care indirectly through creation of interdependent treatment competence, which enables providers to repeatedly deliver interdependent treatment in a flexible and adaptive way. Practical Implications: Providers should carefully implement integrative practices considering patient and disease characteristics, as our findings suggest that more implementation of integrative practices is not necessarily better.

Bioactive glasses synthesized by the sol-gel technique possess many of the qualities associated with an ideal scaffold material for a bone graft substitute. In view of the potential clinical applications, we performed a detailed in vitro study of the biological reactivity of synthesized 58S bioactive glass containing-zinc, in terms of osteoblast morphology, proliferation, and deposition of a mineralized extracellular matrix (ECM). Human Sarcoma Osteoblast (SAOS-2) cells were used to i) assess cytotoxicity by lactate dehydrogenase (LDH) release and ii) evaluate the deposition of a calcified extracellular matrix by ELISA assay and quantitative RT-PCR (qRT-PCR). In comparison with pure silica and 58S, the 58S-Zn0.4 bioglass showed a significant increase in cellular proliferation and deposition of ECM components such as decorin, fibronectin, osteocalcin, osteonectin, osteopontin, type-I and -IIIcollagens. Calcium deposition was significantly higher than on pure silica and 58S samples. Also Alkaline phosphatase(ALP) activity and its protein content was higher with respect to pure silica and 58S. qRT-PCR analysis revealed the up-regulation of type-I collagen, bone sialoprotein and osteopontin genes. All together these results demonstratethe cytocompatibility of 58S-Zn0.4 bioglass and its capability to promote osteoblast differentiation. Source

Carbohydrate Polymers | Year: 2012
Nanocomposite films were prepared by the addition of cellulose nanocrystals (CNCs) eventually surfactant modified (s-CNC) and silver (Ag) nanoparticles in the polylactic acid (PLA) matrix using melt extrusion followed by a film formation process. Multifunctional composite materials were investigated in terms of morphological, mechanical, thermal and antibacterial response. The nanocomposite films maintained the transparency properties of the PLA matrix. Thermal analysis showed increased values of crystallinity in the nanocomposites, more evident in the s-CNC based formulations that had the highest tensile Young modulus. The presence of surfactant favoured the dispersion of cellulose nanocrystals in the polymer matrix and the nucleation effect was remarkably enhanced. Moreover, an antibacterial activity against Staphylococcus aureus and Escherichia coli cells was detected for ternary systems, suggesting that these novel nanocomposites may offer good perspectives for food packaging applications which require an antibacterial effect constant over time. © 2011 Elsevier Ltd.
