    Abstract An 88-year-old man underwent thoracoscopic lower lobectomy for left lung cancer at the age of 87. Ten months later, he was examined closely for abdominal distention, frequent constipation, and anemia with a decreased Hb of 6.1 g/dL. The CT scan revealed an irregular tumor with contrast effect. The patient was diagnosed with malignant tumor of small intestine. At laparotomy, a tumor of 5 cm in diameter was found in the jejunum, and small bowel resection was done. Pathological examination revealed that the tumor was a metastasis of lung cancer. Seven months later, the patient is currently an outpatient, with no evidence of cancer recurrence.

    Abstract We compared laparoscopic gastrectomy and open gastrectomy for the early gastric cancer. Laparoscopic surgery was comparable to laparotomy in terms of operation time and number of lymph node dissections, significantly less bleeding volume, postoperative hospital stay, and lower postoperative complication rate. As a result of E-PASS, surgical invasion was significantly low and the overall risk score was also significantly low. There was no difference in cancer-specific survival, and overall survival was significantly better with laparoscopic distal gastrectomy. Based on the above, laparoscopic gastrectomy is considered to be superior to open gastrectomy as a surgical technique for the early gastric cancer.

    Abstract The patient was a 79-year-old man with complaints of defecation difficulties and constipation. CT scan showed a 7.5 cm diameter mass in the lower rectum, and biopsy revealed GIST. MRI findings suggested prostate invasion, and the patient was started treatment with imatinib. Six months later, the tumor shrank to 4.5 cm in diameter. However, the patient refused surgery and continued taking Imatinib. The tumor continued to shrink gradually. Currently, 7 years later at the age of 86, it is only 2 cm in diameter and its inside has almost completely been replaced with calcifications.

    Abstract The patient is a 74-year-old woman. She had breast cancer(invasive ductal carcinoma, ER[+], PgR[+], HER2[-], Ki-67: 30-40%)and primary right lung cancer with lumbar metastasis, which led to the diagnosis synchronous double cancers of the breast and the lung. We decided to precede surgery for lung cancer because breast cancer was indicated hormonal receptor positive. Breast cancer is treated with anastrozole, thoracoscopic right upper lobectomy was performed for the lung cancer. Radiation therapy was performed for metastatic bone tumors. 13 months later, partial mastectomy sentinel lymph node biopsy performed. The histopathological diagnosis of breast cancer was pT2, pN0, cM0, pStage ⅡA, and histological response was Grade 2a. The remaining breast was treated radiation therapy. The breast cancer has not recurred and is doing well 6 months after surgery. As for primary lung cancer, 19 months have passed since surgery, and the patient is in complete remission without recurrence.

    Abstract Anodic porous alumina templates with controlled microscale geometrical structures were prepared by a process combining mask formation and subsequent selective etching of the alumina layer. In this process, the anisotropic etching of anodic porous alumina allows the preparation of anodic porous alumina with microhole array patterns having high aspect ratios. The electrodeposition of Ni using the obtained alumina templates generated an array of Ni micropillars with high aspect ratios. The height of Ni micropillars could also be controlled by adjusting the thickness of the anodic porous alumina. The obtained Ni micropillar array with a high aspect ratio was applied as a mold for imprinting. The ordered microstructures of TiO

    Abstract Aim: Multiple risk factors are involved in geriatric syndrome (GS) occurring in older adults. Although drug therapy often contributes to GS, the specific causes among older adults in Japan remain unclear. In this study, we examined the possible prescribing cascade rate among older outpatients eligible for Late-stage Elderly Health Insurance and elucidated the differences between GS and GS associated with medication (GSAM) trends.
    Methods: This retrospective study enrolled patients from health insurance claims data in Japan between October 2018 and March 2019; hospitalized patients were excluded. Two groups were identified among the participants with GS: GS (no use of GS-causing medications) and possible-GSAM (p-GSAM; use of GS-causing medications). The collected data were analyzed using the Bell Curve for Excel, and statistical significance was set at P < 0.05.
    Results: In total, 137 781 outpatients were enrolled. Of the 32 259 outpatients who did not use GS-causing medications, 7342 were classified into the GS group. Among 105 522 outpatients who used GS-causing medications, 8347 were classified as having p-GSAM. The mean number of prescriptions was significantly higher in the p-GSAM group than in the GS group (P < 0.01). Furthermore, all GS symptoms showed significant differences, with impaired appetite being the most prevalent in the p-GSAM group than in the GS group (P < 0.01). A possible prescribing cascade was suspected in 2826 (33.9%) of 8347 outpatients in the p-GSAM group.
    Conclusion: Impaired appetite in patients taking GS-causing medications might lead to prescribing cascades. Further studies are needed to prevent such prescribing cascades. Geriatr Gerontol Int 2024; 24: 61-67.
