Abstract

Insights

Early treatment and targeting disease activity in rheumatoid arthritis (RA) significantly improve long-term outcomes. This includes better functional ability, suppressed joint damage, and normalized survival rates, making remission achievable.

Area of Science:

  • Rheumatology
  • Clinical Medicine
  • Immunology

Background:

  • Investigating long-term outcomes in rheumatoid arthritis (RA) over the past decade.
  • Assessing the impact of different treatment strategies on RA progression.

Purpose of the Study:

  • To evaluate the effectiveness of various treatment strategies in patients with DMARD-naïve RA.
  • To determine the long-term impact of treatment-to-target approaches on disease activity, functional ability, and radiologic damage.

Main Methods:

  • Randomized trial comparing four treatment strategies: sequential DMARD monotherapy, step-up combination therapy, initial combination therapy with prednisone, and initial combination therapy with infliximab.
  • Treatment guided by a treat-to-target strategy aiming for DAS ≤ 2.4, with assessments every three months.
  • Evaluation of functional ability (HAQ), radiologic damage (Sharp/vanderHeijde Score), and overall survival.

Main Results:

  • Initial combination therapies (prednisone or infliximab) led to earlier clinical improvement.
  • High rates of remission achieved: up to 50% DAS-remission and 29% drug-free remission.
  • Significant suppression of radiologic damage (median 2 SHS points at 10 years) and functional ability near normal (mean HAQ 0.6).
  • No increased mortality observed (SMR 1.16).

Conclusions:

  • Early treatment initiation is crucial for early clinical improvement in RA.
  • A treat-to-target strategy is key for achieving favorable long-term outcomes.
  • Preventing radiologic damage, disability, achieving drug-free remission, and normalized survival are attainable goals in RA management.

Behaviorism01:28

Behaviorism

The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
The core premise of behaviorism is its focus on observable behavior rather than internal thoughts or feelings. This approach argues that true scientific...

Hindsight Biases01:12

Hindsight Biases

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Cognitive Learning01:21

Cognitive Learning

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Law of Effect01:06

Law of Effect

B.F. Skinner, a prominent figure in behavioral psychology, introduced operant conditioning by emphasizing the role of consequences in shaping behavior. This theory builds upon the law of effect proposed by Edward Thorndike, which posits that behaviors followed by satisfying outcomes are likely to be repeated. In contrast, those followed by unsatisfying outcomes are less likely to recur.
Edward Thorndike's foundational work involved studying learning in animals, particularly using puzzle...

Blind Procedures02:07

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Methods of Documentation V: CBE

Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.
In CBE, healthcare professionals establish predefined standards of practice that define what constitutes...
