■ Paper- Abstract Pancreatic cancer is a malignant tumor that metastasizes to distant organs, such as the liver and lungs from an early stage. Few animal models can reproduce early metastasis. In addition, no model has been reported that reproduces cancer-related hypercoagulability, which is characteristic of pancreatic ductal adenocarcinoma and other adenocarcinomas. We hypothesized that the reason why the commonly used orthotopic cell xenograft model cannot reproduce the disease is inadequate construction of the cancer microenvironment. We developed an orthotopic tissue fragment xenograft model in which tumor tissue was transplanted into the pancreas of mice while preserving the microenvironment. Briefly, we injected single cancer cells subcutaneously to form a tumor, which was then cut with a scalpel into tumor fragments. A fragment was then sutured and fixed to the surface of the pancreatic tail. In this study, we evaluated the superiority of this model over a conventional orthotopic cell xenograft model. As a result, the novel orthotopic tissue xenograft model reproduced early distant metastasis to the liver and lung, nerve invasion, and cancer-related hypercoagulability of human pancreatic cancer, and showed greater similarity to clinical cases than the control orthotopic cell xenograft model.Springer Science and Business Media LLC, Mar. 2025, Medical Molecular Morphology, English[Refereed]Scientific journal

- Background. Mechanically ventilated critically ill patients need the opportunity to communicate their physical and psychosocial concerns to nurses. However, these patients face the unique problem of lacking even the opportunity to communicate. Aims. The study aimed to describe the characteristics of communication opportunities for critically ill mechanically ventilated patients. Methods. The study was designed as a video-based descriptive observational study. Participants included seven mechanically ventilated critically ill patients at the intensive care unit, coronary care unit, or high care unit who were conscious and seven registered nurses (seven pairs). Videos were recorded continuously from 8 am to 4 pm, and the footage was then descriptively analyzed. Data collection took place between July 2019 and June 2020. Results. The total recording time was 668.0 minutes. Of these 668.0 minutes, nurses stayed in the Conversation Area of the Patient for 279.6 minutes, and of these 279.6 minutes, two-way face-to-face communication between nurse and patient occurred for 78.0 minutes. Of these 78.0 minutes, communications were started by nurses for 47.2 minutes (174 scenes) and by patients for 24.2 minutes (36 scenes). The patient-started two-way communication scenes included 37 instances of Patient-Intentional-Action that triggered the start of communication. Actions using the upper limbs were observed in 20 instances and represented the most frequently used body part. The head/face, lower limbs, or trunk were also used in some of the actions. Gestures were the most commonly used action type (14 instances). Other types included lip movement, grimace, leg flex/extension, and cough. Conclusions. We found that nurses tended to start communication more frequently than patients did and that patients demonstrated Patient-Intentional-Action with a variety of actions using various body parts. Communication opportunities for patients were created when nurses took the initiative to start communication or when they noticed and responded to the Patient-Intentional-Action. Our findings demonstrate that nurses need to recognize and always respond to Patient-Intentional-Action and to take the initiative in communicating rather than waiting for the patient to do so.Hindawi Limited, Jul. 2022, Nursing Research and Practice, 2022, 1 - 11, English[Refereed]Scientific journal

- Aim Increased crossing of finger nailfold capillaries could be a novel visual marker of early microvascular damage among type 2 diabetes mellitus patients. Although abdominal obesity is an important driver of early microvascular damage, its association with an increase in the percentage of crossing capillaries remains uncertain. We investigated the association between abdominal obesity and an increase in the percentage of crossing capillaries in the finger nailfold in patients with type 2 diabetes mellitus. Methods This cross-sectional study enrolled 123 type 2 diabetes mellitus patients (age 40-75 years) who visited the outpatient diabetic clinic at Osaka University Hospital between May and October 2019. Abdominal obesity was defined as a waist circumference >= 90 cm in women and >= 85 cm in men. Capillary morphology was assessed by nailfold capillaroscopy based on the simple capillaroscopic definitions of the European League Against Rheumatism Study Group. The association between abdominal obesity and a high percentage of crossing capillaries in the finger nailfold (defined as the highest tertile of crossing capillaries) was analyzed using multivariable logistic regression. Results After adjusting for age, sex, smoking status, regular exercise, duration of diabetes, glycated hemoglobin, hypertension, and dyslipidemia, abdominal obesity was significantly associated with a high percentage of crossing capillaries (multivariable-adjusted odds ratios [95% confidence interval] = 2.70 [1.05-6.90], p = 0.038). Conclusions Abdominal obesity may play an important role in the increase in the percentage of crossing capillaries in the finger nailfold in patients with type 2 diabetes mellitus.Springer Science and Business Media LLC, Jul. 2021, Diabetology International, 12(3) (3), 260 - 267, English[Refereed]Scientific journal
- Aims/Introduction Crossing capillaries in the finger nailfold might potentially be a novel diabetic retinopathy (DR) biomarker that could be assessed non-invasively in the clinical setting. However, the association between crossing capillaries and DR is controversial. This study aimed to investigate the association between the percentage of crossing capillaries in the finger nailfold and DR in patients with type 2 diabetes mellitus.Materials and Methods This cross-sectional study enrolled 108 type 2 diabetes mellitus patients (aged 40-75 years) who visited the outpatient diabetic clinic at Osaka University Hospital, Osaka, Japan, between May and October 2019. Capillary morphology was assessed using nailfold capillaroscopy based on the simple capillaroscopic definitions of the European League Against Rheumatism Study Group. Details of DR and other laboratory data were obtained from medical records. The association between the tertile of the percentage of the crossing capillary and DR was analyzed using multivariable logistic regression.Results After adjusting for age, sex, diabetes duration, glycated hemoglobin, systolic blood pressure, body mass index, and use of renin-angiotensin system inhibitor and antihyperlipidemic medication, the percentage of crossing capillaries was significantly associated with DR (multivariable-adjusted odds ratios for increasing tertiles of the percentage of crossing capillary: 1 [reference], 2.05 [95% confidence interval 0.53-7.94], and 4.33 [95% confidence interval 1.16-16.21]; P-trend = 0.028).Conclusions A higher percentage of crossing capillaries in the nailfold was associated with a higher risk of DR, independent of traditional risk and inhibiting factors, in patients with type 2 diabetes mellitus.Wiley, Jun. 2021, Journal of Diabetes Investigation, 12(6) (6), 1007 - 1014, English[Refereed]Scientific journal
- Purpose This study compared age differences in risk factors for falls requiring treatment in psychiatric patients. Design and Methods An incident database was used to compare fall incidents in patients aged less than 65 years and those aged greater than or equal to 65 years. Findings Approximately 30% of fallers were less than 65 years. Mental status and medication were the main risk factors. Decreased activities of daily living were associated with the most falls in patients greater than or equal to 65 years. Practice Implications Fall risk differed between the two age groups. Medication may play a major role in falls among patients less than 65 years.Lead, Wiley, Jan. 2021, Perspectives in Psychiatric Care, 57(1) (1), 311 - 317, English[Refereed]Scientific journal
- OBJECTIVES: The objective of this study was to evaluate the validity of Eurolung risk models in a Japanese population and assess their utility as predictive indicators for the prognosis. METHODS: Between 2007 and 2014, 612 anatomic lung resections were performed among 694 lung cancer patients in our institution. We analysed the cardiopulmonary morbidity and mortality and compared them with the predicted results. We also investigated the association between the Eurolung aggregate risk scores and the long-term outcomes using the Kaplan-Meier method and a multivariable analysis. RESULTS: The percentage of cardiopulmonary complications was lower than that predicted by Eurolung 1 (22.4% vs 24.6%). The mortality rate was significantly lower than predicted by Eurolung 2 (0.7% vs 3.0%). The morbidity rate was stratified by Aggregate Eurolung 1. The stratification of the mortality rate by the Eurolung 2 aggregate score was also in line with the increase in score, although the observed number of deaths was quite small (4 cases). The 5-year overall survival was clearly separated according to the stratified Aggregate Eurolung 1 and 2 (P < 0.01 and P < 0.01, respectively). Besides pathological stage, both the Aggregate Eurolung 1 (score 0-7 vs 8-20) and 2 (score 0-8 vs 9-19) scores were shown to be independently associated with overall survival on multivariable. CONCLUSIONS: Eurolung risk models cannot be directly applied to the patients in our institution. However, Eurolung aggregate risk scores were helpful not only for stratifying morbidity and mortality after anatomic lung resection but also for predicting the long-term outcomes.Nov. 2019, Interactive cardiovascular and thoracic surgery, 29(5) (5), 722 - 728, English, International magazine[Refereed]Scientific journal
- Falls are an important health issue for older people, as they lead to increased morbidity and mortality and reduced physical function, activities of daily living, and quality of life. Skin sensation is an indicator of the ability to maintain balance, which is a factor in fall risk. We investigated the validity of a computer-controlled plantar-foot sensation-testing instrument (PFS tester) that measures skin sensation. We examined the within-subject reproducibility of skin sensation thresholds and their relationship to balance in older participants. Within-subject skin sensation threshold reproducibility was examined using intraclass correlation coefficients. The skin sensation thresholds showed moderate within-subject reproducibility. The associations between skin sensation thresholds and balance were examined using multiple regression analysis. We found a significant relationship between skin sensation thresholds and balance. The results indicate that the PFS tester is clinically applicable and a reliable indicator of balance ability.Lead, IOS Press, 24 Jul. 2024, Studies in Health Technology and Informatics, 315, 740 - 741, EnglishIntroduction international proceedings
