Objectives: To compare treatment outcomes in patients with late-onset rheumatoid arthritis (LORA) and younger-onset rheumatoid arthritis (YORA).
Methods: We analyzed patients diagnosed with early rheumatoid arthritis (disease duration < 2 years) between 2000 and 2016 in the IORRA cohort. Patients were categorized into LORA (onset at ≥ 65 years) and YORA (onset at < 65 years).
Introduction: Endoscopic transsphenoidal surgery can be performed by two surgeons, including an endoscopist (PE/2S), and by a single surgeon with an endoscope-holder system (PE/1S + H). We analyzed the surgical outcome, and outcome predictors in acromegaly patients in endoscopic transsphenoidal surgery using floor standing pneumatic endoscope-holder system.
Methods: Endoscopic transsphenoidal surgery was performed with PE/1S+H (n = 51) and PE/2S (n = 20).
A 74-year-old woman, who had been receiving olaparib for the treatment of ovarian cancer for more than a year, visited the emergency department complaining of a fever that had lasted for 1 month. She had been taking antipyretics and antibiotics for her fever, but without any effect. Although she had no symptoms other than fever, she had stopped taking olaparib for 1 week before her visit because she had developed anemia caused by myelosuppression from olaparib.

Materials And Methods: This retrospective single-center clinical study was conducted between January 2013 and December 2022. We included consecutive patients who underwent MT for acute large-vessel occlusion of the anterior circulation with low pretreatment DWI-Alberta Stroke Program Early Computed Tomography Scores (ASPECTS) (0-5), effective recanalization [thrombolysis in cerebral infarction (TICI) 2b or TICI3], and magnetic resonance imaging (MRI) acquired before and after MT.
Background: Pituitary apoplexy rarely causes internal carotid artery (ICA) occlusion and acute ischemic stroke. Some cases have been reported, but the neuroimaging findings, including cerebral angiography, have not been discussed.
Observations: A 55-year-old male suffered the sudden onset of right cervical pain and left mild hemiparesis.
Objectives: This article aims to examine the ability of the Rheumatoid Arthritis Observation of Biologic Therapy (RABBIT) risk score to predict the occurrence of serious infections in Japanese patients with rheumatoid arthritis (RA), after initiating their first biologic disease-modifying antirheumatic drug (bDMARD).
Methods: We used data from the Institute of Rheumatology, Rheumatoid Arthritis cohort from 2008 to 2020. Patients with RA who were started on their first bDMARDs were included.
Objectives: We aimed to examine the impact of concomitant interstitial lung disease (ILD) on achieving clinical remission and the occurrence of unfavourable clinical events in patients with RA.
Methods: Among the participants in the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) cohort from 2011 to 2012, patients not achieving remission of 28-joint disease activity score (DAS28) at baseline and those with chest CT images were enrolled. Based on the chest CT images, the patients were divided into two groups: the ILD group and non-ILD group.
Idiopathic pleuroparenchymal fibroelastosis (PPFE) is a rare type of idiopathic interstitial pneumonia, which is characterised by pleural fibrosis and subjacent parenchymal fibroelastosis of the upper lobes. Herein, we present a case of microscopic polyangiitis (MPA) following PPFE. The patient had abnormal shadows on chest radiographs 15 years before the onset of MPA, and the patient was diagnosed with PPFE.

Methods: Measurements were performed using thin slice T2-weighted MRI, and/or time-of-flight (TOI) MR angiography imaging for 64 nonfunctioning pituitary neuroendocrine tumors (NF-pitNETs), 22 growth hormone-producing pitNETs (GH producing pitNETs), and 46 normal controls. We measured the ICD at 3 anatomic levels: at the distal dural ring (ICD-A); at the most concave point of the C4-C5 bend (ICD-B); and at the most convex point of the C4 bend (ICD-C).
Objective: To investigate factors associated with improvements in cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) after combined revascularization surgery for moyamoya disease, with special attention to the size of craniotomy.
Methods: We retrospectively analyzed 35 hemispheres in 27 patients with adult and older pediatric moyamoya disease. CBF and CVR were measured separately in the MCA and ACA territories from acetazolamide-challenged single-photon emission computed tomography before and after 6 months postoperatively, and associations with various factors were analyzed.
Objective: Carotid artery stenting (CAS) is the established treatment strategy of the cervical internal carotid artery (cICA) stenosis, but its use for acute tandem lesions remains controversial. We investigated the clinical and procedural outcomes of management of cICA lesions and evaluated the risk factors for complications.
Methods: Fifty patients who underwent acute mechanical thrombectomy for tandem lesion between January 2014 and June 2022 were included.
Objectives: The aim of this article is to investigate the mortality rate of patients with early rheumatoid arthritis (RA) over the past 17 years.
Methods: Japanese patients with early RA enrolled in the Institute of Rheumatology, Rheumatoid Arthritis cohort from 2001 to 2012 were classified into Groups A (2001-06) and B (2007-12). The standardized mortality ratio (SMR) and 5-year survival rate were calculated.
An 18-year-old Japanese woman with systemic lupus erythematosus experienced dyspnoea, headache, tinnitus, and purpura for 2 weeks and was admitted to our hospital. The patient had been diagnosed with systemic lupus erythematosus and secondary immune thrombocytopenia 8 years before and treated with high-dose prednisolone and mycophenolate mofetil. Since the blood test on admission showed haemolytic anaemia with a positive direct Coombs test and anti-glycoprotein IIb/IIIa antibodies, the patient was initially diagnosed with Evans syndrome (ES).

Methods: A decision-analytic model was used to estimate the cost per American College of Rheumatology response of at least 50% improvement (ACR50) responder and per patient in Clinical Disease Activity Index (CDAI) and Simplified Disease Activity Index (SDAI) remission from a Japanese healthcare payers' perspective over a 2-year time horizon. Clinical characteristics of patients on ABA-1L were matched with those of patients on ABA second or later line (2L+) or tumour necrosis factor inhibitor (TNFi)-1L directly or using propensity scores.
Background: Delayed hyponatremia after pituitary surgery can be treated with the V2-receptor antagonist, oral tolvaptan. We investigated the pharmacological effect of oral tolvaptan against SIAD in patients with hyponatremia after pituitary surgery.
Methods: Thirty-nine patients with pituitary adenoma treated by endoscopic transsphenoidal surgery developed SIAD according to the major guidelines, and 7 patients (17.
Protein kinase A promotes beige adipogenesis downstream from β-adrenergic receptor signaling by phosphorylating proteins, including histone H3 lysine 9 (H3K9) demethylase JMJD1A. To ensure homeostasis, this process needs to be reversible however, this step is not well understood. We show that myosin phosphatase target subunit 1- protein phosphatase 1β (MYPT1-PP1β) phosphatase activity is inhibited via PKA-dependent phosphorylation, which increases phosphorylated JMJD1A and beige adipogenesis.
