ABSTRACT

The design and development of a bio-adhesive hydrogel with on-demand removability and excellent antibacterial activities are meaningful to achieve high wound closure effectiveness and post-wound-closure care, which is desirable in clinical applications. In this work, a series of adhesive antioxidant antibacterial hydrogels containing peptides from Periplaneta americana (PAP) were prepared through multi-dynamic-bond cross-linking among 3,4-dihydroxybenzaldehyde (DBA) containing catechol and aldehyde groups and chitosan grafted with 3-carboxy-4-fluorophenylboronic acid (CS-FPBA) to enable the effective adhesion of skin tissues and prevention of bacterial infection of wound. PAP was derived from alcohol-extracted residues generated during the pharmaceutical process, aiming to minimize resource wastage and achieve the high-value development of such a medicinal insect. The hydrogel was prepared by freezing-thawing with no toxic crosslinkers. The multi-dynamic-bond cross-linking of dynamic borate ester bonds and dynamic Schiff base bonds can achieve reversible breakage and re-formation and the adhesive strength of CS-FPBA-DBA-P-gel treated with a 20 % glucose solution dramatically decreased from 3.79 kPa to 0.35 kPa within 10 s. Additionally, the newly developed hydrogel presents ideal biocompatibility, hemostasis and antibacterial activity against Staphylococcus aureus and Escherichia coli compared to commercial chitosan gel (approximately 50 % higher inhibition rate), demonstrating its great potential in dealing with infected full-thickness skin wounds.

ABSTRACT

PURPOSE: The purpose of this research is to examine the potential of e-health by focusing explicitly on the delivery of health care products and services. The examination of e-health activity is guided by one broad research question, "What is the potential for constructing e-health strategy as an innovative health technology?". A great amount of attention has been given to e-health activity in the present day. However important this form of e-health is, this type of service simply does not face the same constraints that must be addressed by those actually delivering health care services. DESIGN/METHODOLOGY/APPROACH: The researchers employed a qualitative data collection technique to formulate more examples and cases to derive lessons for Jordan. Phone interviews in a random sample were conducted with corporate officers in Jordan in order to reveal the internal organizational structure and business trends, interface issues, marketing strategies, as well as comparing and contrasting the online health world to the traditional health care realm. FINDINGS: Internet-related projects is a top priority for health care information technology executives in the present day, with a cautious approach toward "e-health", as many products have yet to mature, and that the "click and mortar" model may perhaps be the optimal strategy for e-health in Jordan. RESEARCH LIMITATIONS/IMPLICATIONS: This paper reviews the e-health trends to demonstrate the tremendous potential for health-related commercial activity on the internet. However, the researcher examining the barriers facing e-health to the Jordanian health system also pointed out almost insurmountable challenges. PRACTICAL IMPLICATIONS: Despite the apparent promise of e-health, its instability is measured by its failure so far to systematically penetrate the organization of health care. Beyond the pragmatic negotiation of e-health in the immediate context of clinical practice, there are wider issues about how the development/implementation of e-health is funded, about its organization and management at the policy level; and about its potential medico-legal risks. ORIGINALITY/VALUE: It is hoped that the handful of ventures into cyber medicine appears to be coming from a few enterprising physicians who have set up medical practices on the Web.

ABSTRACT

Jordan's relative success in containing costs is the result of public financing of the health insurance system, the health care system reform strategy, and expanding the primary care network, which allows for cost containment and universal access based on the need for services rather than the ability to pay. The shift of costs from the public to the private sector must be curtailed. The determinants of health care (i.e. environment; human biology; life style; and health care system) are the main factors that determine future spending on health.
