Amyloid Fibrils03:03

Amyloid Fibrils

12.0K
Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

372
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Fibril-associated Collagen01:11

Fibril-associated Collagen

3.4K
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

Directing Effect of Substituents: meta-Directing Groups

6.0K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

Cancer Prevention

8.2K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
Some...

Summary
This summary is machine-generated.

Colchicine effectively prevents post-operative atrial fibrillation (AF) after cardiac surgery. While it increases gastrointestinal issues, it does not lead to early treatment discontinuation, suggesting its potential as an adjunctive therapy.

Area of Science:

  • Cardiology
  • Pharmacology

Background:

  • Post-operative atrial fibrillation (AF) is a common complication following cardiac surgery.
  • Inflammatory processes are implicated in the development of post-operative AF.
  • Colchicine, an anti-inflammatory drug, may mitigate this risk.

Purpose of the Study:

  • To evaluate the efficacy and safety of colchicine in preventing post-operative AF.
  • To synthesize evidence from randomized controlled trials (RCTs) on colchicine for post-operative AF prevention.

Main Methods:

  • A systematic literature search was conducted across major databases (PubMed, EMBASE, Web of Science, etc.).
  • RCTs comparing colchicine with placebo for post-operative AF prevention were included.
  • The primary outcome was the incidence of AF within 12 months post-surgery, analyzed using a random-effects model.

Main Results:

  • Analysis of 3 RCTs (912 patients) indicated a significant reduction in post-operative AF with colchicine (RR: 0.65; 95% CI: 0.46 to 0.91).
  • Colchicine use was associated with a higher incidence of gastrointestinal intolerance (RR: 2.20; 95% CI: 1.31 to 3.70).
  • No significant increase in early treatment discontinuation was observed (RR: 1.37; 95% CI: 0.95 to 1.96).

Conclusions:

  • Current evidence supports colchicine's efficacy in preventing post-operative AF.
  • Colchicine may serve as an effective adjunctive prophylactic agent.
  • Further research is needed to optimize treatment protocols and minimize gastrointestinal side effects.
