Regulation of apoptosis during homeostasis and disease in the intestinal epithelium

A single epithelial layer serves as the interface between the organism and the contents of the gastrointestinal tract, underlining the importance of regulating cellular viability despite an onslaught of pathogens, toxins, waste by-products, and cytokines. A balance between cellular proliferation and apoptosis is necessary to maintain this critical barrier. Recent findings have begun to explain the mechanisms by which intestinal epithelial cells are able to survive in such an environment and how loss of normal regulatory processes may lead to inflammatory bowel disease (IBD) and predispose to inflammation-associated neoplasia. This review focuses on the regulation of physiological apoptosis in development and homeostasis and on pathological apoptosis in intestinal disease, inflammation, and neoplasia, identifying remaining questions and areas of needed investigation.     

Drug users’ adherence to a 6-month vaccination protocol: Effects of motivational incentives

Vaccines represent a new and promising avenue of treatment for drug abuse but pose new medication adherence challenges due to prolonged and widely spaced administration schedules. This study examined effects of prize-based incentives on retention and medication adherence among 26 cocaine users involved in a 6-month hepatitis B vaccination series. Participants could meet with research staff weekly for 24 weeks and receive 7 injections containing either the Hepatitis B vaccine or a placebo. All participants received $10 at each weekly visit (maximum of $240). Those randomly assigned to the incentive program received additional monetary payments on an escalating schedule for attendance at weekly monitoring and vaccination visits with maximum possible earnings of $751. Group attendance diverged after study week 8 with attendance better sustained in the incentive than control group (group by time interaction, p = .035). Overall percent of weekly sessions attended was 82% for incentive versus 64% for control (p = .139). Receiving all scheduled injections were 77% of incentive versus 46% of control participants (p = .107). A significantly larger percentage (74% versus 51%; p = .016) of injections were received by incentive versus control participants on the originally scheduled day. Results suggest that monetary incentives can successfully motivate drug users to attend sessions regularly and to receive injected medications in a more reliable and timely manner than may be seen under usual care procedures. Thus, incentives may be useful for addressing adherence and allowing participants to reap the full benefits of newly developed medications.     

A Pharmacy Blueprint for Electronic Medical Record Implementation Success

Objective:

Implementation of an integrated, electronic medical record (EMR) has been promoted as a means of improving patient safety and quality. While there are a few reports of such processes that incorporate computerized prescriber order entry, pharmacy verification, an electronic medication administration record (eMAR), point-of-care barcode scanning, and clinical decision support, there are no published reports on how a pharmacy department can best participate in implementing such a process across a multihospital health care system.

Method:

This article relates the experience of the design, build, deployment, and maintenance of an integrated EMR solution from the pharmacy perspective. It describes a 9-month planning and build phase and the subsequent rollout at 8 hospitals over the following 13 months.

Results:

Key components to success are identified, as well as a set of guiding principles that proved invaluable in decision making and dispute resolution. Labor/personnel requirements for the various stages of the process are discussed, as are issues involving medication workflow analysis, drug database considerations, the development of clinical order sets, and incorporation of bar-code scanning of medications. Recommended implementation and maintenance strategies are presented, and the impact of EMR implementation on the pharmacy practice model and revenue analysis are examined.

Conclusion:

Adherence to the principles and practices outlined in this article can assist pharmacy administrators and clinicians during all medication-related phases of the development, implementation, and maintenance of an EMR solution. Furthermore, review and incorporation of some or all of practices presented may help ease the process and ensure its success.
