Acta Mathematica Sinica,English Series 2024年

作者： Satoshi YAMAGUCHI Eiichi NAKAI katsunori SHIMOMURA Department of Mathematics Ibaraki University

In this paper we extend the duality(■)*= H1(Rd) to generalized Campanato spaces with variable growth condition Lp,φ(Rd) instead of BMO(Rd). We also extend the characterization of Cc∞omp(Rd)BMO(Rd)by Uchiyama(1978) to ■. Moreover, using this characterization, we prove the boundedness of singular and fractional integral operators on ■.The function space Lp,φ(Rd) treated in this paper covers the case that it is coincide with Lipαon one area, with BMO on another area and with the Morrey space on the other area, for example.

Aims: To investigate the effects of a newly developed color-coded educational glucose control instruction (COLOR), combined with a color-displayed glucose meter on changes in type-2 diabetes patient’s behavior and their HbA1c levels. Material and Methods: Patients using a COLOR-self-monitoring of blood glucose (SMBG) method were instructed to record daily blood glucose levels with red (high glucose ≥ 180 mg/dL) or blue (low glucose ≤ 70 mg/dL) colored circles on their SMBG notebooks according to the colors displayed on the glucose meter. Results: COLOR-SMBG showed an improved the actual behavior modification scores by 14% compared to Conventional group at 1-month follow-up

Quantifying the Effect of Metformin 1000 mg/day in Japanese Patients with Type 2 Diabetes

引用

International Journal of Clinical Medicine 2014年第15期5卷 894-901页

作者： katsunori suzuki Taishi Yoshioka Yoko Wakui Division of Endocrinology and Metabolism Saiseikai Niigata Daini Hospital Niigata Japan

Objective: To examine the effect of high-dose metformin on glucose metabolism in Japanese patients with type 2 diabetes. Method: A total of 144 patients with type 2 diabetes who could be followed up for 6 months after their dose of metformin was increased to 1000 mg/day (from 750 mg/day or less) were examined. The dose of metformin was increased from 750 mg/day in 70 subjects (250-mg dose increase) and from 500 mg/day in 74 subjects (500-mg dose increase). Results: After the dose increased to 1000 mg/day, HbA1c was significantly decreased by 0.65% ± 0.7%, 0.42% ± 0.5%, and 0.87% ± 0.7% in all subjects, the 250-mg dose increase group, and the 500-mg dose increase group, respectively. No significant change was observed in weight. Analysis by BMI (2 and ≥25 kg/m2) revealed a comparable significant decrease in HbA1c in all subjects, the 250-mg dose increase group, and the 500-mg dose increase group. Analysis by duration of diabetes showed a significant decrease in HbA1c regardless of the duration. Conclusion: Increasing the metformin dose to 1000 mg/day showed a significant antihyperglycemic effect over 6 months in Japanese patients with type 2 diabetes. Blood glucose improved regardless of the duration of diabetes or the presence or absence of obesity. Overall tolerability was favorable.

Sitagliptin for Elderly Patients Aged 75 Years or Older with Inadequately Controlled Type 2 Diabetes with Common Antidiabetes Treatments

引用

International Journal of Clinical Medicine 2015年第9期6卷 672-681页

作者： katsunori suzuki Yurie Mistuma Takaaki Sato Mariko Hatta Division of Endocrinology and Metabolism Saiseikai Niigata Daini Hospital Niigata Japan Department of Nutrition Saiseikai Niigata Daini Hospital Niigata Japan

Background: The purpose of this study was to evaluate the effects of sitagliptin in elderly patients with type 2 diabetes aged 75 years or older versus those aged 65 - 74 years. Methods: Outpatients aged 65 years or older with type 2 diabetes who received sitagliptin at a dose of 50 mg daily for 6 months were divided into two groups: those who were 75 years and older and those who were 65 - 74 years. The efficacy and safety were retrospectively evaluated by comparison of laboratory values before and after the administration of sitagliptin and by review of adverse events after treatment. Results: One hundred and twelve older patients with type 2 diabetes were studied. Six months after the initiation of sitagliptin, participants’ hemoglobin A1c was significantly decreased by 1.09% ± 0.8% in 65 - 74-year-olds (66 patients;mean age, 69.1 ± 3.0 years;mean HbA1c before administration, 8.4% ± 0.8%) and by 1.05% ± 0.8% in patients 75 years or older (46 patients;mean age, 79.8 ± 4.1 years;mean HbA1c before administration, 8.5% ± 0.7%). There was no significant difference in hemoglobin A1c between the two groups. Furthermore, sitagliptin was well tolerated in both age groups. Conclusions: In elderly patients (75 years or older) with type 2 diabetes, the effect of sitagliptin was similar that in older patients (younger than 75 years) with type 2 diabetes.

Background: Working memory is an executive function that plays an important role in many aspects of daily life, and its impairment in patients with attention-deficit/hyperactivity disorder (ADHD) affects quality of life. The dorsolateral prefrontal cortex (DLPFC) has been a good target site for transcranial direct current stimulation (tDCS) due to its intense involvement in working memory. In our 2018 study, tDCS improved visual-verbal working memory in healthy subjects. Objective: This study examines the effects of tDCS on ADHD patients, particularly on verbal working memory. Methods: We conducted an experiment involving verbal working memory of two modalities, visual and auditory, and a sustained attention task that could affect working memory in 9 ADHD patients. Active or sham tDCS was applied to the left DLPFC in a single-blind crossover design. Results: tDCS significantly improved the accuracy of visual-verbal working memory. In contrast, tDCS did not affect auditory-verbal working memory and sustained attention. Conclusion: tDCS to the left DLPFC improved visual-verbal working memory in ADHD patients, with important implications for potential ADHD treatments.

Prognostic Impact of Surgical Margin Width in Hepatectomy for Colorectal Liver Metastasis

引用

Journal of Clinical and Translational Hepatology 2023年第3期11卷 705-717页

As for resection for colorectal liver metastasis (CRLM), secur-ing an adequate surgical margin is important for achieving a better prognosis. However, it is often difficult to achieve ade-quate margins for the resection of CRLM. So the current sur-vival impact of sub-centi/millimeter surgical margins in he-patectomy for CRLM should be evaluated. In the current era of multidisciplinary treatment options, this review focused on the prognostic impact of a sub-centi/millimeter surgical margin width in hepatectomy for CRLM. We systematically reviewed retrospective studies that clearly described the sur-gical margin width for hepatectomy for CRLM. We selected studies conducted since 2000 that involved patients diag-nosed as having CRLM. We focused on studies that investi-gated not only surgical margins, but also microscopic surgical curability such as R0 (microscopically complete resection) or R1 (microscopically incomplete resection), which clearly de-scribe their definitions. Based on our literature review, 1, 2, or 5 mm was considered the minimum surgical margin width for hepatectomy for CRLM. Although a surgical margin width of 1 mm is acceptable for hepatectomy for CRLM, submil-limeter margins, which are defined as R1 in many reports, are only acceptable for limited patients such as those who have undergone preoperative chemotherapy. Zero-mm mar-gins are also acceptable in limited patients such as those who show a good response to preoperative chemotherapy. New chemotherapy agents have been reported to reduce the prognostic impact of a narrow surgical margin width. The incidence of margin recurrence, which is a major concern regarding R1 resection of CRLM, is about 20-30% according to the majority of earlier reports. As evaluations of the actual prognostic impact of the surgical margin remain difficult, fur-ther study is warranted.
