Abstract Background and Aim Combined hepatocellular–cholangiocarcinoma (CHC) is a primary liver cancer containing both hepatocellular carcinoma (HCC) intrahepatic cholangiocarcinoma (ICC) elements. Its reported clinicopathological features prognoses have varied because of its low prevalence. This study aimed to clarify these aspects CHC. Methods We enrolled 28 patients with CHC, 1050 HCC, 100 ICC compared the characteristics prognosis CHC HCC ICC. also analyzed prognostic factors, recurrence...

Abstract Hepatocellular carcinoma ( HCC ) is a highly prevalent cancer with poor prognosis. The correlation between overexpression of fatty acid‐binding protein 5 FABP 5) and malignant potential tumor growth metastasis in several cancers has been previously reported. However, the expression behavior remains unknown. We compared patient characteristics paired adjacent noncancerous liver tissues from 243 patients who underwent surgical resection primary . Cell proliferation, invasion,...

Despite recommendations from clinical practice guidelines to initiate and titrate guideline-directed medical therapy (GDMT) during their hospitalization, patients with acute heart failure (AHF) are frequently undertreated. In this study we aimed clarify GDMT implementation titration rates, as well the long-term outcomes, in hospitalized AHF patients.

Long-term outcomes of iatrogenic coronary dissection and perforation in patients undergoing percutaneous intervention (PCI) remains under-investigated. We analyzed 8,721 consecutive discharged after PCI between 2008 2019 from Keio Cardiovascular (KiCS) multicenter prospective registry the Tokyo metropolitan area. Significant was defined as persistent contrast medium extravasation or spiral filling defects with complete distal impaired flow. The primary outcome a composite all-cause death,...

Mycoplasma pneumoniae infection is conventionally diagnosed using serum antibody testing, microbial culture, and genetic testing. Recently, immunochromatography-based rapid mycoplasma antigen test kits have been developed commercialised for diagnosis of M. infection. However, as these do not provide sufficient sensitivity specificity, a kit with improved accuracy desired. The present prospective study evaluated diagnostic system utilizing newly silver amplification immunochromatography (SAI)...

Antiphospholipid syndrome (APS) is clinically characterized by arterial or venous thrombosis; however, non-thromboembolic lung manifestations, such as diffuse alveolar hemorrhage (DAH), have also been previously reported. DAH relatively common in APS patients with systemic lupus erythematosus, although it rare primary APS. We encountered a 78-year-old man who presented hemoptysis and dyspnea. Chest CT showed ground-glass opacity pulmonary thromboembolism. He was successfully treated...

The prognosis of mycoplasma pneumonia in adults is generally favorable, but a few patients show progression to acute respiratory distress syndrome (ARDS). We have described the management patient who showed ARDS. A 26-year-old male with no significant past medical or social history presented 5-day fever. Following this, he was diagnosed bacterial and treated tazobactam/piperacillin; however, little clinical improvement this treatment approach. an antigen test him azithromycin prednisolone....

The high expression Fatty Acid Binding Protein 5 (FABP5) has been reported its malignant potential in several cancers. However, function FABP5 HCC remains unknown. We analyzed correlation between and behavior using tissues human cell lines. Methods: A total 231 samples were obtained through our institute subjected to immunohistochemical analysis. In vitro, protein lines was assessed by Western blot...
