Alzheimer disease (AD) may develop after the onset of type 2 diabetes mellitus (T2DM), and the risk of AD may depend on the antidiabetic drug administered. We compared the risk of AD among 66 085 patients (≥ 65 years) with T2DM (1250 having concomitant AD) who had been administered antidiabetic drug monotherapy for T2DM who had voluntarily reported themselves in the Food and Drug Administration Adverse Event Reporting System. The risk of AD from the use of different antidiabetic drug monotherapies compared to that of metformin monotherapy was assessed by logistic regression. Rosiglitazone (adjusted reporting odds ratio [aROR] = 0.11; 95% confidence interval [CI]: 0.07-0.17; P < .001), exenatide (aROR = 0.22; 95% CI: 0.11-0.37; P < .001), liraglutide (aROR = 0.36; 95% CI: 0.19-0.62; P < .001), dulaglutide (aROR = 0.39; 95% CI: 0.17-0.77; P = .014), and sitagliptin (aROR = 0.75; 95% CI: 0.60-0.93; P = .011) were found to have a significantly lower associated risk of AD than that of metformin. Therefore, the administration of glucagon-like peptide 1 receptor agonists and rosiglitazone may reduce the risk of AD in patients with T2DM.

Article 25-2 of the Japanese Pharmacists' Act was revised in June 2014, establishing the position of pharmacists as "advisors on the use of pharmaceuticals." Prior to the Act's revision, we investigated the perceptions of patients and pharmacists about pharmacists' roles using a social science methodology. We also examined current opinions and necessary factors for the future growth and development of pharmacists. This questionnaire survey was conducted using an internet method. Patients and pharmacists answered 12 questions. Responses from 529 patients and 338 pharmacists were analyzed. For all items, pharmacists' awareness of their roles exceeded patients' awareness of the roles. In this study, the difference between pharmacist and patient awareness was larger than in similar research conducted in the United States. The greatest difference was observed in three items: "Understanding the effects of the drugs the patients are taking" (rate of high ratings: pharmacists 80.2%, patients 37.8%), "Understanding the health changes caused by the drugs dispensed to the patients" (pharmacists 80.2%, patients 28.4%), and "Consciously protecting patients from the adverse effects of drugs" (pharmacists 82.8%, patients 42.2%), indicating role discrepancy. Partition analysis indicated the three factors for a pharmacist to be regarded as a drug therapy or medication specialist: "The patient regards the pharmacist as his/her family or regular pharmacist," "The pharmacist is making it easy for a patient to talk with him/her" and "The pharmacist is aware of a patient's use of products other than prescribed drugs, such as over the counter (OTC) medications or health foods and nutritional supplements." Future efforts are necessary to resolve role discrepancy and implement ongoing monitoring.

Type 2 diabetes mellitus (T2DM) is a risk factor for depression. Since brain insulin resistance plays a potential role in depression, the future risk of depression in patients with T2DM may be altered depending on the class of oral hypoglycemic agent (OHA) used for T2DM therapy. The aim of the present study was to determine if specific classes of OHAs are associated with a risk for comorbid depression in T2DM. Japanese adult patients with T2DM (n = 40 214) were divided into a case group (with depression; n = 1979) and control group (without depression; n = 38 235). After adjustment for age [adjusted odds ratio (AOR) for 10 years: 1.03; 95% confidence interval (CI): 0.99‐1.07; P = .1211], sex [AOR for female: 1.39; 95% CI: 1.26‐1.53; P < .0001], hemoglobin A1c [AOR for 1.0%: 1.18; 95% CI: 1.11‐1.26; P < .0001], duration of T2DM [AOR for 1 year: 1.00; 95% CI: 0.99‐1.01; P = .4089], and history of seven medical conditions, the odds ratios for the development of depression was significantly lower for dipeptidyl peptidase‐4 (DPP‐4) inhibitors [AOR: 0.31; 95% CI: 0.24‐0.42; P < .0001]. However, there was no significant association for the other classes of OHAs. Therefore, this study finds that there is less risk of depression associated with the use of DPP‐4 inhibitors for the treatment of T2DM.

Pharmacists applied deprescribing, which is a process for the rational use of drugs, for 13 at-home patients. The standard used for the rational use of drugs was the``Guidelines for Medical Treatment and Its Safety in the Elderly'' (the Guidelines). The results of the deprescribing were discussed with physicians to determine prescriptions. After the prescription change, activities of daily living (ADL) and QOL were assessed using the Barthel Index and SF-36v2, respectively. Potentially inappropriate medications (PIMs) were detected in 10 of the 13 patients (76.9％). This detection rate is higher than previous PIM detection rates of 48.4％ and 40.4％ reported in prescriptions for home-care patients in Japan under the Beers and STOPP/START criteria. The Guidelines appeared useful as a decision support tool for deprescribing. The patients continuing the changed prescriptions showed no decrease in ADL or QOL after deprescribing, suggesting its rationality. The 10 measurement items of the Barthel Index were all suitable for evaluating the physical conditions of the patients. Meanwhile, SF-36v2 includes many items, but few indexes were directly applicable.Key words-deprescribing; potentially inappropriate medication; home-care patient; activities of daily living; QOL; criteria One agent less as physician prescribed a compounding drug.
