Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

15.3K
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 I: Introduction

426
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

12.0K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

476
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...

Rheumatic Heart Disease III: Medical Management

282
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...

Rheumatic Heart Disease IV: Nursing Management

AssessmentA comprehensive assessment is essential in managing a patient with rheumatic heart disease (RHD). Begin with obtaining a detailed medical history, including recent streptococcal infections, a history of rheumatic fever, or previously diagnosed rheumatic heart disease. Assess the patient for symptoms such as fever, chest pain, widespread joint pain (arthralgia), tachycardia, pericardial friction rub, muffled heart sounds, heart murmurs, peripheral edema, subcutaneous nodules, and...

Area of Science:

  • Rheumatology
  • Immunology
  • Epidemiology

Background:

  • Rheumatoid arthritis (RA) is a prevalent autoimmune disorder causing joint inflammation.
  • RA affects 0.24-1% of the population with diverse clinical presentations.
  • Disease progression involves preclinical to chronic stages with variable pathogenic mechanisms.

Purpose of the Study:

  • To review the epidemiology of rheumatoid arthritis.
  • To summarize the complex pathogenesis of RA.
  • To discuss current diagnostic options for RA.

  • Analysis of diagnostic strategies for RA.

Main Results:

  • Identified key risk factors including smoking, obesity, age, and gender.
  • Highlighted the intricate interplay of genetic and immunological factors in RA.
  • Emphasized the need for tailored therapeutic approaches due to disease heterogeneity.

Conclusions:

  • A comprehensive understanding of RA epidemiology and pathogenesis is crucial.
  • Advances in understanding RA pathophysiology are driving new therapeutic developments.
  • Effective RA management requires consideration of individual patient factors and disease variability.
