RESUMO
BACKGROUND: Medication-related problems (MRPs) are a major healthcare burden. The rate of MRPs in those ≥65 years old is â¼50 events per 1000 person-years, and contributes to a four-fold higher hospitalization rate when compared to younger patients. Medication therapy management (MTM) can identify MRPs in high-risk patients. However, in 2015, only 12.9% of Medicare patients qualified for MTM services through their Part D plan. OBJECTIVE: To examine the type and frequency of MRPs in community-dwelling Medicare beneficiaries and which patient factors are associated with having ≥1 MRP. METHODS: Fourteen health clinics targeting Medicare beneficiaries were held in 10 Northern/Central California cities during Fall 2017. Trained student pharmacists, supervised by licensed pharmacists, conducted comprehensive medication reviews. Sociodemographic, chronic condition, medication, and MRP data were collected via standardized surveys. RESULTS: MTM services were provided to 910 patients, of which 633 (69.6%) had at least 1 MRP. The most common MRPs were severe drug-drug interaction [nâ¯=â¯297(33.4%)] and untreated condition [nâ¯=â¯134 (14.7%). Individuals with MRPs took significantly more prescription and over-the-counter medications. Additionally, those with MRPs were more likely to be subsidy recipients and in a Medicare Advantage Prescription Drug Plan. A total of 120 (13%) individuals were found to have had an MRP severe enough to warrant prescriber follow-up. CONCLUSIONS: Although only a fraction of Medicare beneficiaries qualify for MTM services through their Part D plan, many can benefit from such services. Understanding the type, frequency, and factors contributing to MRPs is imperative to identify and avoid negative sequelae. Reduction of MRPs can potentially improve patient clinical outcomes, increase quality-of-life, and decrease overall cost of care.

Transcriptional factor paired box 6 (PAX6) is very important for the development of the eyes, central nervous system, and pancreas. PAX6 mutations are associated with a diabetic phenotype and abnormal glucose metabolism. Our previous study showed that PAX6 directly bound to and activated the prohormone convertase 1/3 (Pc1/3) gene promoter and subsequently regulated proinsulin processing. Prohormone convertase 2 (PC2) is the essential enzyme for pancreatic proinsulin processing. To study the regulation of PAX6 in Pc2 expression, we did research on the pancreas of Pax6 R266Stop mutant mice, where truncated mutations happened in the C-terminal of the PAX6 protein. Our studies showed that the mutant PAX6 protein was stable and regulated the activity of Pc2 promoter as shown by luciferase activity assays. We found that the wild-type PAX6 protein imparts a transcriptional effect, and the mutant PAX6 can also regulate the downstream molecules. The results provide new insights into the mechanism of truncated PAX6 in regulating the functions of the pancreas and endocrine system.
