Long-term effects of abatacept on atherosclerosis and arthritis in older vs. younger patients with rheumatoid arthritis: 3-year results of a prospective, multicenter, observational study.

Background: We aimed to reveal the effect of abatacept (ABT) on atherosclerosis in rheumatoid arthritis (RA) patients, 3-year efficacy for arthritis, and safety in a population of older vs. younger patients.

Methods: In this open-label, prospective, observational study, patients were stratified into four groups: younger (20-64 years old) and older (≥ 65 years) patients taking ABT (AY and AO) and conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) (CY and CO).

Real-world clinical decisions of physicians in the management of Takayasu arteritis and giant cell arteritis in Japan: A cross-sectional web questionnaire survey.

Objectives: The aim is to access the real-world clinical management of physicians who treat Takayasu arteritis (TAK) and giant cell arteritis (GCA) after the publication of the Japanese Circulation Society (JCS) 2017 Guidelines for the Management of Vasculitis Syndrome.

Methods: This descriptive, cross-sectional study utilized self-administered electronic questionnaires, which were answered in February 2022 by physicians treating TAK or GCA and registered with Macromill Inc.

Results: The 329 survey respondents were enrolled.

Development of risk-score model in patients with negative surgical margin after robot-assisted radical prostatectomy.

A total of 739 patients underwent RARP as initial treatment for PCa from November 2011 to October 2018. Data on BCR status, clinical and pathological parameters were collected from the clinical records. After excluding cases with neoadjuvant and/or adjuvant therapies, presence of lymph node or distant metastasis, and positive SM, a total of 537 cases were eligible for the final analysis.

Oral pathobiont chaperon usher pili provide site-specific adaptation for the inflamed gut mucosa.

The ectopic gut colonization by orally derived pathobionts has been implicated in the pathogenesis of various gastrointestinal diseases, including inflammatory bowel disease (IBD). For example, gut colonization by orally derived spp. has been linked to IBD in mice and humans.

Platelet and large platelet ratios are useful in predicting severity of COVID-19.

The role of platelets in coronavirus disease (COVID-19) severity requires further exploration. To determine whether the platelet index is useful in predicting COVID-19 severity, we compared the platelet index in patients with higher and lower oxygen requirements (≥ 4 L/min vs. < 4 L/min) and patients without COVID-19.

Systematic review for the treatment of older rheumatoid arthritis patients informing the 2024 update of the Japan College of Rheumatology clinical practice guidelines for the management of rheumatoid arthritis.

Objectives: To update an evidence base informing the 2024 Japan College of Rheumatology clinical practice guidelines for the management of rheumatoid arthritis (RA) in older adults.

Methods: Four clinical questions (CQs) regarding efficacy and safety of drug treatment were evaluated, with CQ1 addressing methotrexate (MTX), CQ2 biological disease-modifying antirheumatic drugs, CQ3 Janus kinase (JAK) inhibitors, and CQ4 glucocorticoids (GCs). Quality of the evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation system.

Metabolic network of the gut microbiota in inflammatory bowel disease.

Gut dysbiosis is closely linked to the pathogenesis of inflammatory bowel disease (IBD). Emerging studies highlight the relationship between host metabolism and the modulation of gut microbiota composition through regulating the luminal microenvironment. In IBD, various disease-associated factors contribute to the significant perturbation of host metabolism.

Effectiveness and safety of treat-to-target strategy for methotrexate-naïve rheumatoid arthritis patients >75 years of age.

Objectives: To identify differences in effectiveness and safety of a treat-to-target (T2T) strategy comparing late-onset MTX-naïve RA patients (LORA) ≥75 or <75 years of age.

Methods: Treatment was adjusted to target low disease activity with conventional synthetic DMARDs followed by biologic DMARDs (bDMARDs) in LORA ≥75 years ( = 98, mean age 80.0 years) and LORA <75 years ( = 99) with moderate-high disease activity.

A meta-analysis of the gut microbiome in inflammatory bowel disease patients identifies disease-associated small molecules.

Changes in the gut microbiome have been associated with several human diseases, but the molecular and functional details underlying these associations remain largely unknown. Here, we performed a multi-cohort analysis of small molecule biosynthetic gene clusters (BGCs) in 5,306 metagenomic samples of the gut microbiome from 2,033 Inflammatory Bowel Disease (IBD) patients and 833 matched healthy subjects and identified a group of Clostridia-derived BGCs that are significantly associated with IBD. Using synthetic biology, we discovered and solved the structures of six fatty acid amides as the products of the IBD-enriched BGCs.

Trastuzumab deruxtecan in patients with human epidermal growth factor receptor 2-expressing salivary gland carcinoma: a pooled analysis of two phase I studies.

Background: HER2-expressing salivary gland carcinoma (SGC) is associated with poor prognosis. Trastuzumab deruxtecan (T-DXd, DS-8201) has shown evidence of antitumor activity for several HER2-expressing solid tumors in multiple studies. This study aimed to present the efficacy and safety of T-DXd in patients with HER2-expressing SGC from a pooled analysis.

Organ Damage and Quality of Life in Takayasu Arteritis - Evidence From a National Registry Analysis.

Background: Takayasu arteritis, affecting primarily young women, damages large arteries and organs. We examined the impact of disease duration and sex on organ damage and quality of life using Japan's Intractable Disease Registry.

Methods and results: After refining data, 2,013 of 2,795 patients were included in the study.

Association between Major Adverse Cardiovascular Events and the Liver Fibrosis Score in Patients with and without Coronary Artery Disease: From the FU-CCTA Registry.

The liver fibrosis score reflects the degree of hepatic scarring and has been reported to be associated with cardiovascular disease. Using a coronary artery computed tomography angiography registry at the Fukuoka University Hospital (FU-CCTA registry), we investigated the association between major adverse cardiovascular events (MACEs) and the liver fibrosis score (fibrosis-4 index (FIB-4I)) in 612 patients who underwent CCTA to screen for coronary artery disease and performed a prognosis survey for up to 5 years. The primary endpoint was MACEs (all-cause mortality, acute myocardial infarction, ischemic stroke, coronary revascularization).

Ravulizumab Can Effectively Treat Ischemic Enteritis Caused by Paroxysmal Nocturnal Hemoglobinuria.

Ischemic colitis is a common disease with a good prognosis; however, complications can occur in the presence of a serious underlying disease. Herein, we present a case report in which characteristic findings on lower gastrointestinal endoscopy led to a diagnosis of paroxysmal nocturnal hemoglobinuria (PNH). An 82-year-old woman visited our hospital for chronic heart and renal failure.

Challenges faced by nurses engaged in rheumatology care in Japan.

Objectives: This study aimed to identify the challenges faced by nurses engaged in rheumatology care in Japan.

Methods: We conducted a questionnaire survey of nurses in Japan in 2020 on challenges experienced in rheumatology care. The participants were nurses certified by the Japan Rheumatism Foundation.
