BACKGROUND
Lack of awareness may be a significant barrier to participation by low- and middle-income seniors in pharmaceutical cost-assistance programs.
OBJECTIVE
The goal of this study was to determine whether older adults' awareness of 2 major state and federal pharmaceutical cost-assistance programs was associated with the seniors' ability to access and process information about assistance programs.
METHODS
Data were gathered from a cross-sectional study of independently living, English- or Spanish-speaking adults aged > or =60 years. Participants were interviewed in 30 community-based settings (19 apartment complexes and 11 senior centers) in New York, New York. The analysis focused on adults aged > or =65 years who lacked Medicaid coverage. Multivariable logistic regression was used to model program awareness as a function of information access (family/social support, attendance at senior or community centers and places of worship, viewing of live health insurance presentations, instrumental activities of daily living, site of medical care, computer use, and having a proxy decision maker for health insurance matters) and information-processing ability (education level, English proficiency, health literacy, and cognitive function). The main outcome measure was awareness of New York's state pharmaceutical assistance program (Elderly Pharmaceutical Insurance Coverage [EPIC]]) and the federal Medicare Part D low-income subsidy program (Extra Help).
RESULTS
A total of 269 patients were enrolled (mean [SD] age, 76.9 [7.5] years; 32.0% male; 39.9% white). Awareness of the programs differed widely: 77.3%) knew of EPIC! and 22.3% knew of Extra Help. In multivariable analysis, study participants were more likely to have heard of the EPIC program if they had attended a live presentation about health insurance issues (adjusted odds ratio [AOR], 3.40; 95% CI, 1.20-9.61) and less likely if they received care in a clinic (AOR, 0.45; 95% CI, 0.23-0.92). Awareness of Extra Help in the multivariable models was more likely among study participants who had viewed a live health insurance presentation (AOR, 3.35; 95% CI, 1.55-7.24) and less likely for those with inadequate health literacy (AOR, 0.15; 95% CI, 0.03-0.74).
CONCLUSIONS
Viewing of live health insurance presentations and adequate health literacy were associated with greater awareness of important pharmaceutical cost-assistance programs in this study in low-income, elderly individuals. The findings suggest that use of live presentations, in addition to health literacy materials and messages, may be important strategies in promoting knowledge of and enrollment in state and federal pharmaceutical cost-assistance programs for low-income seniors.

BACKGROUND
Experimental human stem cell transplantation to the heart has begun, but the mechanisms underlying benefits seen in preclinical models, both at the site of cell injection and at more distant regions, remain uncertain. We hypothesize that these benefits can be best understood first at the level of key intracellular signaling cascades in the host myocardium, which can be responsible for functional and structural preservation of the heart.
STUDY DESIGN
Western blot and ELISA were used to assess key pathways that regulate cardiac myocyte survival and hypertrophy in both the infarct/borderzone and remote myocardium of C57/B6 mouse hearts subjected to coronary artery ligation, with subsequent injection of either vehicle or bone marrow-derived adult mesenchymal stem cells (MSC).
RESULTS
Improved left ventricular function with MSC transplantation was associated with a relative preservation of Akt phosphorylation (activation) and of phosphorylation of downstream mediators of cell survival and hypertrophy. There was no substantial difference in activation of mitogen-activated protein kinase p38, and activation of the antiapoptotic mitogen-activated protein kinase extracellular signal-regulated kinase was lower at 1 week after MSC treatment, but rose beyond controls by week 2. Similar changes were observed in both the infarct/borderzone and the remote myocardium.
CONCLUSION
Stem cell transplantation in the post-MI murine myocardium is associated with preservation of Akt signaling. Together with a possible later increase in extracellular signal-regulated kinase activation, this signaling change might be responsible for cardioprotection. Additional focused investigation might identify elements in transplantation regimens that optimize this mechanism of benefit, and that can increase the likelihood of human clinical success.

BACKGROUND
Although physicians sometimes use the futility rationale to limit the use of life-sustaining treatments, little is known about how surrogate decision makers view this rationale. We sought to determine the attitudes of surrogates of patients who are critically ill toward whether physicians can predict futility and whether these attitudes predict surrogates' willingness to discontinue life support when faced with predictions of futility.
METHODS
This multicenter, mixed qualitative and quantitative study took place at three hospitals in California from 2006 to 2007. We conducted semistructured interviews with surrogate decision makers for 50 patients who were critically ill and incapacitated that addressed their beliefs about medical futility and inductively developed an organizing framework to describe these beliefs. We used a hypothetical scenario with a modified time-trade-off design to examine the relationship between a patient's prognosis and a surrogate's willingness to withdraw life support. We used a mixed-effects regression model to examine the association between surrogates' attitudes about futility and their willingness to limit life support in the face of a very poor prognosis. Validation methods included the use and integration of multiple data sources, multidisciplinary analysis, and member checking.
RESULTS
Sixty-four percent of surrogates (n = 32; 95% confidence interval [CI], 49 to 77%) expressed doubt about the accuracy of physicians' futility predictions, 32% of surrogates (n = 16; 95% CI, 20 to 47%) elected to continue life support with a < 1% survival estimate, and 18% of surrogates (n = 9; 95% CI, 9 to 31%) elected to continue treatment when the physician believed that the patient had no chance of survival. Surrogates with religious objections to the futility rationale (n = 18) were more likely to request continued life support (odds ratio, 4; 95% CI, 1.2 to 14.0; p = 0.03) than those with secular or experiential objections (n = 15; odds ratio, 0.95; 95% CI, 0.3 to 3.4; p = 0.90).
CONCLUSIONS
Doubt about physicians' ability to predict medical futility is common among surrogate decision makers. The nature of the doubt may have implications for responding to conflicts about futility in clinical practice.
