Chronic disseminated intravascular coagulation (DIC) complicates 5.7% of thoracic aortic aneurysm. DIC with thoracic aortic aneurysm is characterized by hyperfibrinolysis, but usually shows a stable condition in a state of compensated non-overt DIC with limited hemorrhagic symptoms. However, in some cases, hemorrhage caused by external factors may induce uncompensated overt DIC and lead to serious hemorrhagic tendencies. In the present study, we report a patient with a thoracic aortic aneurysm complicated by DIC who exhibited marked hemorrhagic tendencies. DIC remarkably improved following administration of recombinant human soluble thrombomodulin.

Vitronectin (VN) is an extracellular matrix protein with a crucial role in regulating bone remodeling. In this study, we aimed to investigate the effect of VN deficiency in a mouse model of osteoporosis induced by ovariectomy (OVX).The findings revealed that the absence of VN led to an increase in the activity of tartrate-resistant acid phosphatase (TRAP), a marker for osteoclasts, in the plasma of OVX-operated mice. TRAP staining further demonstrated that VN deficiency resulted in a higher number of osteoclasts within the femurs of OVX-operated mice. X-ray micro-computed tomography analysis of the femurs in OVX-operated mice indicated that VN deficiency significantly suppressed the OVX-induced increase of marrow area and total volume of bone. Additionally, we assessed structural model index (SMI) and degree of anisotropy (DA) as indices of osteoporosis. The results showed that VN deficiency effectively attenuated the OVX-induced increase in SMI and DA among OVX-operated mice. In summary, our study demonstrates the vital role of VN in regulating osteoclastogenesis and bone remodeling in the mouse model of osteoporosis.

The clinical competence needed by every beginning resident and the present status of such competencewere examined in August 1998 through questionnaires distributed to clinical educators and the nursing staff of university hospitals and clinical training hospitals designated by the Ministry of Health and Welfare. Completed questionnaires were returned by 576 (65.9%) of clinical educators and nursing staff. With a cluster analysis of the necessity and the present status of clinical competence, 21 items for clinical competence were identified as those most requiring evaluation by the national examination. These 21 items included 11 items for clinical competence in the cognitive domain, 8 items in the psychomotor domain, and 2 in the affective domain. In about half of the direct answers obtained from clinical educators, evaluations were considered necessary for 15 items of clinical competence, of which 13 belonged to the cognitive domain. These results were consistent with the present status. However, practical examinations have also attracted increasing attention, as the results included strong demands that the national examination evaluate some basic clinical skills, such as physical examination and measurement of vital signs. However, about 30 % of authorities governing the national examination thought no changes are needed in the national examination.

Background/Aims: Covered self-expandable metallic stents (cSEMS) have become popular for endoscopic ultrasound-guided hepaticogastrostomy with transmural stenting (EUS-HGS). We compared the time to recurrent biliary obstruction (TRBO), complications, and reintervention rates between EUS-HGS using plastic stent (PS) and cSEMS in patients with unresectable malignancies at multicenter institutions in Japan. Methods: Patients with unresectable malignant biliary obstruction who underwent EUS-HGS between April 2015 and July 2020 at any of the six participating facilities were enrolled. Primary endpoint: TRBO; secondary endpoints: rate of complications other than recurrent biliary obstruction and technical success rate of reintervention were evaluated. Results: PS and cSEMS were used for EUS-HGS in 109 and 43 patients, respectively. The TRBO was significantly longer in the cSEMS group than in the PS group (646 vs. 202 days). Multivariate analysis identified two independent factors associated with a favorable TRBO: combined EUS-guided antegrade stenting with EUS-HGS and the use of cSEMS. No significant difference was observed in the rate of complications other than recurrent biliary obstruction between the two groups. The technical success rate of reintervention was 85.7% for PS and 100% for cSEMS (p=0.309). Conclusions cSEMS might be a better option for EUS-HGS in patients with unresectable malignancies, given the longer TRBO.

Purpose: The purpose of this study is to clarify the factors related to the content of consultation in the cancer nursing outpatient department of Gunma University Hospital. Method: A retrospective survey was conducted with 1084 cases, excluding the unknown cases, from 1308 consultations in FY2019. Survey items included age, gender, consulter, number of uses, treatment status, consultation content, etc. We conducted χ2 tests, and binomial logistic regression analysis between the content of the consultation and the attributes of the user. Results: The treatment-related content was associated with the following factors: 70s or older, family/relatives only, presence of recurrence/metastasis, first use, pre-treatment, urinary organs, uterine/ovary, and unknown primary. The body-related content was associated with the following factors: under treatment, post-treatment, no recurrence/metastasis, and digestive organs. The mental health-related content was associated with 30s or younger, 40s–60s, patient only, and second time or more. The social aspects-related content was associated with the following factors: patient only, family/relatives only, no recurrence/metastasis, and breast. Conclusion: The results reveal that associated factors differ by consultation content. These findings can be used to prepare for consultation based on the relevant associated factors.
