Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids01:21

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

156
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

309
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

Exercise and Cardiovascular Response01:20

Exercise and Cardiovascular Response

869
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Summary

Corticosteroid injections are common for triathletes with knee pain, offering subjective improvement and a quick return to sport for many. However, this study found no significant association between injections and faster return to sport compared to other treatments.

Area of Science:

  • Sports Medicine
  • Orthopedics
  • Exercise Physiology

Background:

  • Knee pain is prevalent among triathletes, impacting performance and training.
  • Corticosteroid injections are frequently used for athletic knee pain, but their specific efficacy in triathletes remains understudied.

Purpose of the Study:

  • To evaluate the attitudes, usage patterns, subjective effectiveness, and return-to-sport timelines associated with corticosteroid injections versus alternative treatments for knee pain in triathletes.

Main Methods:

  • An observational study utilizing a 13-question survey distributed online to triathletes during the COVID-19 pandemic.
  • Data collected from 61 triathlete respondents regarding their experiences with knee pain treatments.

Main Results:

  • 97% of respondents experienced knee pain; 63% received corticosteroid injections, predominantly in older triathletes (average age 51).
  • Most triathletes reported subjective pain improvement with injections, with many experiencing relief for 2-3 months or over a year (often with multiple injections).
  • While 80.6% returned to sport within a month post-injection, this was not significantly faster than alternative methods (73.7% return within a month).

Conclusions:

  • Corticosteroid injections are frequently used by older triathletes for knee pain, providing subjective pain relief.
  • No significant evidence supports corticosteroid injections leading to a quicker return to sport compared to alternative treatments in this population.
  • Triathletes should receive comprehensive counseling on injection timing, potential side effects, and associated risks.
