The ability to trigger changes to material properties with external stimuli, so‐called “smart” behavior, has enabled novel technologies for a wide range of healthcare applications. Response to small changes in temperature is particularly attractive, where material transformations may be triggered by contact with the human body. Thermoreversible gelators are materials where warming triggers reversible phase change from low viscosity polymer solution to a gel state. These systems can be generated by the exploitation of macromolecules with lower critical solution temperatures included in their architectures. The resultant materials are attractive for topical and mucosal drug delivery, as well as for injectables. In addition, the materials are attractive for tissue engineering and 3D printing. The fundamental science underpinning these systems is described, along with progress in each class of material and their applications. Significant opportunities exist in the fundamental understanding of how polymer chemistry and nanoscience describe the performance of these systems and guide the rational design of novel systems. Furthermore, barriers to translating technologies must be addressed, for example, rigorous toxicological evaluation is rarely conducted. As such, applications remain tied to narrow fields, and advancements will be made where the existing knowledge in these areas may be applied to novel problems of science.

Purpose: This exploratory study used a set of four obstacle constructs derived from both the existing literature and our earlier work to describe the diverse end-of-life scenarios observed for a group of residents in a long-term care facility. Design and Methods: Data from a retrospective chart review and both quantitative and qualitative methods of data collection and analysis were used to examine in-depth the end-of-life experiences of all nursing home residents ( N ϭ 41) who died on the nursing care unit of a large continuing care retirement community during an 18-month period. Results: A hierarchy of obstacles to palliation and end-of-life care seems to exist in long-term care settings that begins with the lack of recognition that restorative, rehabilitative, or curative treatment futility has commenced. The next three obstacles in sequence include lack of communication among decision makers, no agreement on a course of care, and failure to implement a timely plan of care. Implications: The findings highlight the importance of determining treatment futility as an initial step in the successful delivery of palliative and end-oflife care to residents in long-term care followed by the need for a deliberate and proactive series of actions and care planning processes.

This is a report of a controlled, prospective, longitudinal trial of an intervention to affect medical students' attitudes toward aging. Members of the Class of 2002 at the University of Oklahoma College of Medicine were assigned a senior mentor (a community-dwelling older person) upon matriculation into medical school. Students were required to perform a structured interview with the mentor once per semester for the first 2 preclinical years and to discuss these interviews in small groups mediated by geriatrics faculty. Members of the Class of 2001 were controls. Attitudes toward aging were determined using the Aging Semantic Differential (ASD) attitude scale in August 1998 and again at the end of the second year of medical school. Initial mean ASD scores were not significantly different for the two groups. Although both classes experienced improvements in their ASD scores from Time 0 to Time 1, the improvement for the class of 2002 was significantly greater than that for the class of 2001 (2001 class mean = 0.17, 2002 class mean = 0.40, t = -3.09, degrees of freedom (df) = 219, P =.002). This difference held up under controls for sex, age, prior visits to a nursing home, prior work/volunteering in an old-age environment, and a prior course on aging (Model F = 3.00, df = 6/214, P =.008; class F = 9.70, df = 1, P =.002). It was concluded that a low-intensity intervention to introduce entering medical students to healthy older people might have a positive effect on attitudes toward aging.

Employing the Andersen/Neuman model of health behavior, this research compares the medically vulnerable (elderly, poor, and uninsured) with their less vulnerable counterparts with regard to (1) health and disability status, (2) likelihood of physician use, and (3) (among users) amount of physician use. Data were from the Oklahoma Behavioral Risk Factor Surveillance Survey and the Area Resource File. Findings indicate that the medically vulnerable are more likely to be disabled and to experience poorer health than the nonmedically vulnerable. The uninsured are less likely to have seen a physician in the past year. Among those who have seen a physician in the past year, the uninsured and Medicare recipients without supplemental insurance experienced fewer physician visits. The results point to inequalities in the distribution of physician care that may be exacerbated by federal policies that are currently under consideration.

Education and clinical experience embedded in a continuous quality-improvement model are needed to ensure sustained change that will overcome the multiple, interwoven barriers to providing appropriate palliative care.

In this article, the personal, idiosyncratic elements of the nursing home search and selection process from the point Of king that institutionalization was necessary through thermal selection decision, is investigated. Data are derived from interviews with 25 nursing home patient "sponsors" (the individuals identified by nursing homes as the primary contact person or responsible person for the patient) of recently admitted nursing home patients and 3 significant other informants for a total sample size of 28. Their stories reveal a rather hectic and stressful processor which families were ill-prepared, and often undertaken during the crisis of hospitalization. Most respondents did not comment on the use or benefit of printed nursing home guides. Instead, respondents simply looked for facility that was convenient to home or work and relied heavily on word-of-mouth recommendations by friends and family members.

Caregiver medication administration hassles represent a complex, multidimensional construct that warrants consideration in studies of contemporary family caregiver stress, strain, and burden.
