Objective In recent decades, living conditions have changed drastically. However, there are few data regarding the interaction between living conditions and the risk of ischemic stroke (IS) in young adults. The present study explored the association between living conditions or marital status and the risk factors, etiology, and outcome of IS in young adults. ⋯ Furthermore, in the solitary group, the proportions of men, unmarried individuals, and current smokers were significantly higher than in the cohabiting group. In addition, poor outcomes (modified Rankin Scale ≥4) of IS were more common in the solitary group than in the cohabiting group. Conclusion Our study showed that not only conventional vascular risk factors but also living conditions, especially living alone while unmarried, were independent risk factors for IS in young adults.

Objective In routine practice, central venous ports without blood return (CVPWBRs) are common. However, very few studies have reported on the viable period of CVPWBR use. We therefore investigated this period by retrospectively analyzing the venographic images of CVPWBRs. ⋯ Conclusion There are two learning points in our study. First, venography is needed when the CVP becomes a CVPWBR for the first time due to the high risk, and second, CVPWBRs can be used for a relatively long period in patients without major complications. It is necessary to develop an appropriate follow-up management method for CVPWBRs in prospective studies.

Desminopathy is a cardiac and skeletal myopathy caused by disease-causing variants in the desmin (DES) gene and represents a subgroup of myofibrillar myopathies, where cytoplasmic desmin-postive immunoreactivity is the pathological hallmark. We herein report a 28-year-old Japanese man who was initially diagnosed with sporadic hypertrophic cardiomyopathy with atrioventricular block at 9 years old and developed weakness in the soft palate and extremities. ⋯ Genetic testing confirmed a de novo mutation of DES, which has already been linked to desminopathy. As the molecular diagnosis of desminopathy is challenging, particularly if patients show predominantly cardiac signs and a routine skeletal muscle biopsy is unavailable, these characteristic pathological findings of endomyocardial proteinase K-resistant desmin aggregates might aid in clinical practice.

Objective The effect of sarcopenia on the prognosis of patients undergoing chemotherapy for unresectable pancreatic ductal adenocarcinoma remains largely unexplored. In this retrospective study, we investigated the relationship between sarcopenia and the prognosis of patients receiving first-line nanoparticle albumin-bound paclitaxel plus gemcitabine for unresectable pancreatic ductal adenocarcinoma. Methods We enrolled 251 patients with unresectable metastatic or locally advanced pancreatic ductal adenocarcinoma who had received chemotherapy between January 2015 and December 2020 at Kitasato University Hospital. ⋯ There were no significant differences between groups with regard to major adverse events or drug toxicity occurrences. Both the progression-free and overall survival were significantly shorter in the skeletal muscle index loss group than in the non-skeletal muscle index loss group (p=0.026 and 0.045, respectively). Conclusion Skeletal muscle index loss during the initial treatment phase may be an early marker for the long-term prognosis of patients receiving nanoparticle albumin-bound paclitaxel plus gemcitabine as first-line treatment for unresectable pancreatic ductal adenocarcinoma.

A 76-year-old man undergoing hemodialysis complained of pain and discoloration of his right finger. The hemodialysis arteriovenous fistula was in the right upper extremity. Ultrasonography showed right subclavian artery occlusion. ⋯ Thus, we performed the procedure after exposing the proximal brachial artery. We were able to recanalize the subclavian artery and restore blood flow to the right upper extremity. When the lesion is on the side of the arteriovenous fistula and approaching from the lower extremity is difficult, exposure of the proximal brachial artery can be considered.
