    Abstract Introduction: Early detection of cognitive impairment in older adults is important for the prevention of dementia. Intra-individual variability in reaction time (IIV-RT) during go/no-go tasks can be used for the early detection of cognitive impairment in older adults living in the community. This study aimed to determine the relationship between IIV-RT and cognitive function during go/no-go tasks and the cutoff values for determining the risk of cognitive impairment in community-dwelling older adults.
    Methods: This study included 31 older adults without cognitive impairment, 15 community-dwelling older adults with cognitive impairment, and 34 healthy young adults. All participants performed a go/no-go task to assess the IIV-RT. Additionally, older adults underwent neuropsychological testing. Based on the results of the Japanese version of the Montreal Test of Cognitive Abilities (MoCA-J), older adults were divided into those with normal cognition and those with cognitive impairment.
    Results: There were significant differences in the IIV-RT among groups, including a higher IIV in the cognitively impaired group than in young adults and cognitively normal older adults. Moreover, the IIV-RT was correlated with the MoCA-J (
    Conclusions: These findings indicate that the IIV-RT during go/no-go tasks is a useful early indicator of cognitive impairment in community-dwelling older adults.

    Abstract We report a case of recurrent breast cancer with bone metastasis in a premenopausal woman. A 46-year-old woman underwent mastectomy for right breast cancer 6 years ago. Histopathological diagnosis was invasive ductal carcinoma, T2N3aM0, stage ⅢC. She received adjuvant chemotherapy and irradiation followed by tamoxifen. Four and a half years after surgery, serum tumor marker levels elevated, and bone metastasis in the sacral region was revealed by PET-CT scan. After suppressing ovarian function with LH-RH agonist, we switched the endocrine therapy from tamoxifen to letrozole with a CDK4/6 inhibitor. Five months after starting administration of abemaciclib, the bone metastasis disappeared on PET-CT. The elevated tumor markers normalized and have continued to decrease. Abemaciclib combined with endocrine therapy was significantly effective as first-line treatment for premenopausal women with metastatic breast cancer.

    Abstract We report a case of advanced breast cancer in an elderly patient effectively treated with locoregional therapy. The patient was an 81-year-old woman who presented with an increasing right breast lump. The tumor was 55 mm in diameter, accompanied by fixation to pectoral muscle. A core needle biopsy for right breast tumor led to a diagnosis of mucinous carcinoma, positive for estrogen receptor(ER)and progesterone receptor(PgR), negative for HER2/neu. The Ki-67 positive cell index was 10%. A bone scintigraphy revealed multiple bone metastases, so, we confirmed the diagnosis as T4cN2aM1, Stage Ⅳ. She initiated endocrine therapy by letrozole. By changing the endocrine therapy to toremifene followed by fulvestrant, the therapy achieved a partial response. However, the size of the primary tumor increased accompanied by bleeding, and surgical resection of the right breast was performed for local control. The locoregional surgery was effective, improving the patient's quality of life. She was administered lapatinib as anti-HER2 therapy in addition to the endocrine therapy. Two years and 6 months after surgery, there has been no worsening of bone metastasis or appearance of visceral metastasis.

    Abstract Background: Contrast-induced nephropathy (CIN) caused by exposure to radioactive contrast media can cause acute kidney injury in patients with chronic kidney disease (CKD). We developed a multifaceted approach in a CIN-quality improvement (QI) program based on a shorter saline hydration protocol for the prevention of CIN in outpatients and assessed the effect of our CIN-QI program on decreasing both the incidence rate of CIN and overall use of contrast agents in patients undergoing contrast-enhanced computed tomography (CT).
    Methods: We conducted a multi-center prospective interrupted time-series study from 2006 to 2018 investigating the efficacy of a CIN-QI program in preventing CIN among outpatients with CKD. An automatic medical record system alert was implemented to instruct physicians to consult a nephrologist and administer prophylactic hydration and follow-up when ordering contrast-enhanced imaging in patients with an estimated glomerular filtration rate (eGFR) <45 mL/min/1.73 m2. The primary outcomes were the rates of prophylactic hydration and follow-up kidney function assessment, and the incidence of CIN for eligible patients. The usage rate of contrast-enhanced CT was also examined.
    Results: A total of 95 594 patients who underwent contrast-enhanced CT were included in the study. The annual prophylactic hydration rate before the CIN-QI program ranged from 2.0% to 23.2% but increased to 59.2%-75.2% during the CIN-QI program (P < .001). The annual rate of follow-up kidney function testing also improved from 18.6%-25.8% to 34.1%-42.5% after implementation of the CIN-QI program (P < .001). The rate of CIN significantly declined in level by 10.0% at the start of the CIN-QI program (P = .002) and in trend by 2.9%/year (P < .001). The number of contrast-enhanced CT orders showed a positive level change in patients with advanced CKD, who were the CIN-QI program target group of patients with eGFR <45 mL/min/1.73 m2, at the start of the implementation of the CIN-QI program. After implementing the CIN-QI program, the number of contrast-enhanced CT orders showed a negative trend change across all patients, which decreased from -1.4%/year to -10.0%/year for patients with advanced CKD.
    Conclusion: The multifaceted approach in the CIN-QI program may be associated with the decreased incidence of CIN and increased rates of prophylactic hydration and follow-up kidney function testing.

    Abstract Background: Pancreatic ductal carcinoma (PDAC) is an extremely poor prognostic disease. Even though multidisciplinary treatment for PDAC has developed, supportive therapies, such as nutritional therapy or perioperative rehabilitation to sustain and complete aggressive treatment, have not yet been well-established in PDAC. The aim of this study was to elucidate the relationship between the combined index using psoas muscle mass index (PMI) values and controlling nutritional status (CONUT) score and prognosis.
    Methods: We included 101 patients diagnosed with PDAC who underwent radical pancreatectomy with regional lymphadenectomy. The cut-off value was set at the first quartile (male, 6.3 cm
    Results: In the poor general condition group, the proportion of elderly people over 70 years of age was significantly higher than that in the other groups (p < 0.001). The poor general condition group had a significantly worse prognosis than the good and moderate general condition groups (p = 0.012 and p = 0.037). The 5-year survival rates were 10.9%, 22.3%, and 36.1% in the poor, moderate, and good general condition groups, respectively. In multivariate analysis, poor general condition, with both low PMI and malnutrition status, was an independent poor prognostic factor for postoperative OS (hazard ratio 2.161, p = 0.031).
    Conclusions: The combination of PMI and CONUT scores may be useful for predicting the prognosis of patients with PDAC after radical surgery.

    Abstract Background: Living kidney transplant donors are classified as stage 3 chronic kidney disease after kidney donation. For this reason, we provide daily lifestyle guidance, such as blood pressure and weight management before surgery, and dietary counseling focused on salt restriction. We emphasize providing lifestyle guidance after kidney donation.
    Method: At Osaka Medical and Pharmaceutical University Hospital, living kidney donors are scheduled for their first postoperative visit 1 month after kidney donation, followed by regular checkups every 6 months after that, starting 3 months after the initial visit. When living kidney donors come to the Renal Replacement Therapy Selection Outpatient Clinic before kidney transplantation, we provide sufficient explanations of the potential risks that may arise after kidney donation and ensure that they understand the importance of regular postoperative checkups. Apart from cases where patients reside far away, and we ask another hospital to provide postoperative follow-up, we can achieve regular checkups for almost all cases.
    Results: Eighty-four living kidney transplant donors are being followed up at Osaka Medical and Pharmaceutical University Hospital. The average age is 59.8 ± 11.8 years, showing a trend of aging. Among the donors under follow-up, 7 developed hyperlipidemia, 2 developed hypertension, and 1 developed diabetes as new-onset lifestyle diseases after kidney donation.
    Conclusion: The ability to empathize with and support the anxieties associated with kidney donation and build a strong relationship of trust with the donors has become a significant factor in achieving a high rate of regular checkups after kidney donation. As a result, it has led to early detection and intervention for donor diseases, contributing to the maintenance of their health. Managing lifestyle-related diseases after kidney donation is essential for living kidney donors.

    Abstract Background: Evidence linking chronic kidney disease (CKD) and sleep duration is inconsistent. This study examined whether sleep duration is associated with a long-term risk of kidney function decline.
    Methods: This retrospective, longitudinal cohort study included 82 001 participants who visited a primary care centre in Japan. Participants were categorized into CKD risk groups and sleep duration categories according to their self-reported average nightly sleep duration. The relationship between average nightly sleep duration and the incidence of composite renal outcome comprised a ≥40% reduction in estimated glomerular filtration rate (eGFR) from baseline and a decline in eGFR to <15 mL/min/1.73 m² was evaluated.
    Results: The mean age and eGFR (±standard deviation) of the patient cohort were 45.8 (±12.4) years and 81.8 (±15.4) mL/min/1.73 m², respectively. A total of 41 891 participants (51.1%) were women. During the median follow-up of 5.1 years [interquartile range 2.2-9.6], 4214 (5.1%) participants achieved the composite renal outcome. Only the long and very long sleep durations (≥8 h/night) were associated with an increased incidence of the composite renal outcome compared with the reference duration (7 h/night) [adjusted odds ratio (OR) 1.22 and 1.44; 95% confidence interval (CI) 1.09-1.36 and 1.13-1.84, for long and very long sleep durations, respectively]. Furthermore, this association was significant for both long and very long sleep durations in the low CKD risk group but only for long sleep duration in the intermediate CKD risk group. The results of the sex-specific analysis showed that men had a decreased risk of achieving the composite renal outcome (OR 0.91; 95% CI 0.79-1.06), while there was an increased risk for women (OR 1.14; 95% CI 1.02-1.28).
    Conclusions: Average sleep durations ≥8 h/night were associated with an increased incidence of poor renal outcomes over time. However, a longitudinal cohort study is required to confirm whether sleep duration can prevent poor renal outcomes.
