Abstract

Objectives:

A global downward trend in the number of rheumatoid arthritis (RA)-related surgeries has been reported. The purpose of our study was to investigate the latest trends in RA-related surgeries in a single-centre Japanese RA cohort.

Methods:

This study was a retrospective analysis of RA-related surgeries between 2001 and 2020 in the Institute of Rheumatology Rheumatoid Arthritis cohort. An average of 4944 patients per semi-annual survey was included in the study. The primary goal was to analyse the half-year period prevalence proportion (HPP) of RA-related surgeries in a 20-year period, and the secondary goal was to analyse the HPP of surgeries by site or by categories of disease activity.

Results:

There has been a downward trend in the HPP of RA-related surgeries in the 20-year study period. The total HPP of RA-related surgeries decreased by 50.3% during the 20-year study period. There was a significant decrease in knee, hip, shoulder/elbow, and hand procedures. Only foot/ankle joint surgeries significantly increased in volume during this period (p = .001). The HPP of RA-related surgeries remained unchanged in patients with remission or low disease activity.

Conclusions:

The number of RA-related surgeries decreased over a 20-year period, but foot/ankle joint surgeries increased in the site-specific evaluation.

Inflammatory Bowel Disease V: Surgical Management

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Rheumatic Heart Disease III: Medical Management

Rheumatic Heart Disease III: Medical Management

Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...

Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
