Multicenter Study
The Glucose-lowering Efficacy of Sitagliptin in Obese Japanese Patients with Type 2 Diabetes.
Objective Dipeptidyl peptidase-4 (DPP-4) inhibitors are the most frequently prescribed oral hypoglycemic agents in Japan. Although a relationship between the efficacy of DPP-4 inhibitors and the body mass index (BMI) has been reported, this relationship is controversial. We investigated whether the BMI value affects the glucose-lowering efficacy of sitagliptin in obese Japanese patients with type 2 diabetes. ⋯ A multiple logistic regression analysis revealed that the baseline HOMA-β function and HbA1c level and a baseline BMI value of ≥30 kg/m2 significantly contributed to the response to sitagliptin treatment. Conclusion The results indicated that sitagliptin treatment was effective in controlling glucose metabolism disorder in obese Japanese patients with type 2 diabetes. However, the efficacy of sitagliptin treatment might be attenuated in severely obese patients, such as those with a BMI value of ≥30 kg/m2.

Long-term Efficacy and Safety of Sitagliptin in Elderly Patients with Type 2 Diabetes Mellitus.
Objective We herein conducted a retrospective study to evaluate the long-term efficacy and safety of sitagliptin treatment in elderly patients with type 2 diabetes mellitus. Methods We analyzed the changes in glycemic control in 112 Japanese type 2 diabetes patients over 65 years of age treated with 50 mg/day sitagliptin. Hemoglobin A1c (HbA1c) levels, liver and kidney functions, and usage of hypoglycemic agents were recorded for 24 months. ⋯ No patient experienced severe hypoglycemia episodes, and aspartate transaminase, alanine transaminase, gamma-glutamyl transpeptidase, and the eGFR remained unchanged. The dose of sulfonylurea was finally decreased in 72% of patients treated with sulfonylurea. Conclusion Sitagliptin treatment continually decreases the HbA1c level for 24 months and is useful to reduce the dose of sulfonylurea in elderly patients with type 2 diabetes.

The Differences in the Epidemiology and Predictors of Death between Candidemia Acquired in Intensive Care Units and Other Hospital Settings.
The burden of candidemia is shifting from intensive care units (ICU) to non-ICU settings. This study aimed to define the differences in epidemiology and predictors of death between ICU-acquired candidemia (ICUAC) and non-ICUAC. ⋯ The Candida species and antifungal resistance profiles in patients with ICUAC were similar to non-ICUAC patients, but led to worse outcomes. The protective and risk factors for death may therefore be relevant for the clinical management of patients with candidemia in ICU and non-ICU settings.

Randomized Controlled Trial Multicenter Study
Effects of hydrochlorothiazide on oxidative stress and pulse pressure in hypertensive patients with chronic stroke: the EMINENT study.
Thiazide diuretics are reported to have antioxidant effects and reduce pulse pressure (PP). The aim of this study was to elucidate whether hydrochlorothiazide additionally exerts such effects in stroke patients under treatment with losartan. ⋯ In this study, hydrochlorothiazide treatment did not provide any additional benefits over non-diuretic antihypertensive drugs in terms of antioxidant effects or reducing PP.

Multicenter Study Clinical Trial
Effects of esomeprazole on sleep in patients with gastroesophageal reflux disease as assessed on actigraphy.
Gastroesophageal reflux disease (GERD) is strongly associated with sleep disturbances. Although treatment with proton pump inhibitors (PPIs) helps to improve GERD symptoms and subjective sleep parameters, the effects of PPI therapy on objective sleep parameters are conflicting. The aim of this study was to examine the effects of esomeprazole treatment on GERD symptoms and sleep parameters assessed using actigraphs and questionnaires. ⋯ Esomeprazole treatment significantly improves various objective sleep parameters in Japanese patients with GERD. Further placebo-controlled randomized trials are needed to obtain detailed results.
