RESUMEN
Personal health records (PHRs) typically employ "passive" communication strategies, such as non-personalized medical text, rather than direct patient engagement in care. Currently there is a call for more active PHRs that directly engage patients in an effort to improve their health by offering elements such as personalized medical information, health coaches, and secure messaging with primary care providers. As part of a randomized clinical trial comparing "passive" with "active" PHRs, we explore patients' experiences with using an "active" PHR known as HealthTrak. The "passive" elements of this PHR included problem lists, medication lists, information about patient allergies and immunizations, medical and surgical histories, lab test results, health reminders, and secure messaging. The active arm included all of these elements and added personalized alerts delivered through the secure messaging platform to patients for services coming due based on various demographic features (including age and sex) and chronic medical conditions. Our participants were part of the larger clinical trial and were eligible if they had been randomized to the active PHR arm, one that included regular personalized alerts. We conducted focus group discussions on the benefits of this active PHR for patients who are at risk for cardiovascular disease. Forty-one patients agreed to participate and were organized into five separate focus group sessions. Three main themes emerged from the qualitatively analyzed focus groups: participants reported that the active PHR promoted better communication with providers; enabled them to more effectively partner with their providers; and helped them become more proactive about tracking their health information. In conclusion, patients reported improved communication, partnership with their providers, and a sense of self-management, thus adding insights for PHR designers hoping to address low adoption rates and other patient barriers to the development and use of the technology.

Keeping patients with complex medical illnesses up to date with their preventive care and chronic disease management services, such as lipid testing and retinal exam in patients with diabetes, is challenging. Within a commercially available electronic health record (EHR) with a secure personal health record (PHR), we developed a system that sends up to three weekly reminders to patients who will soon be due for preventive care services. The reminder messages reside within the secure PHR, which is linked to the EHR, and are displayed on a screen where patients can also send to the physician's office an electronic message to request appointments for the needed services. The reminder messages stop when the patient logs on to review the reminders. The system, designed with patient input, groups together all services that will be due in the next 3 months to avoid repeatedly messaging the patient. After 2 months, the cycle of reminders begins again. This system, which is feasible and economical to build, has the potential to improve care and compliance with quality measures.

Lentiviruses have been increasingly used for genetic modification of human cells including embryonic stem (ES) cells. Using four ubiquitous promoters--cytomegalovirus (CMV), cytomegalovirus immediate-early enhancer/chicken beta-actin hybrid (CAG), phosphoglycerate kinase (PGK), and human elongation factor-1alpha (EF1alpha)--in a lentiviral vector to drive the expression of the enhanced green fluorescent protein (EGFP) gene in human ES cells and mouse ES cells, we determined the extent of EGFP suppression by assessing the percentage of cells that were transduced with the EGFP gene but did not fluoresce green. A much higher level of transgene suppression was observed in human ES cells as compared to mouse ES cells. The suppression was also highly promoter dependent, leading to inactivation of more than 95% of the EGFP genes under the CMV or CAG promoter while only 55% under the PGK promoter. No promoter-dependent suppression was observed in transient transfection of human ES cells. Thus, the common phenomenon of poor transgene expression in human ES cells may be caused mainly by suppression of the transgene right after transduction and integration. Cautions should be taken to choose the optimal promoter when lentiviruses are used for genetic modification of human ES cells.
