Reactivity of Enols01:18

Reactivity of Enols

4.0K
Enols are a class of compounds where a hydroxyl group is attached to a carbon–carbon double bond, which implies that it is a vinyl alcohol. A carbonyl compound with an α hydrogen undergoes keto–enol tautomerism and remains in equilibrium with its tautomer, the enol form. Usually, the keto tautomer is present in a higher concentration than the enol tautomer due to the higher bond energy of C=O compared to C=C. Moreover, the direction of the keto–enol equilibrium is...

Fixed Action Patterns01:06

Fixed Action Patterns

17.6K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Reactivity of Enolate Ions01:23

Reactivity of Enolate Ions

3.3K
Enolate ions are formed by the acid–base reaction of a carbonyl compound with a base. This leads to deprotonation of the α hydrogen atom, leading to a resonance-stabilized enolate ion where one of the contributing structures is an oxyanion, which imparts additional stability. Therefore, the proton on the α carbon is more acidic in nature than that of other sp3-hybridized C–H bonds but less acidic than those in O–H bonds where the negative charge in the conjugate...

Radical Reactivity: Overview01:11

Radical Reactivity: Overview

2.6K
Radicals, the highly reactive species, gain stability by undergoing three different reactions. The first reaction involves a radical-radical coupling, in which a radical combines with another radical, forming a spin‐paired molecule. The second reaction is between a radical and a spin‐paired molecule, generating a new radical and a new spin‐paired molecule. The third reaction is radical decomposition in a unimolecular reaction, forming a new radical and a spin‐paired...

Summary
This summary is machine-generated.

Reactive arthritis (ReA) may be decreasing in prevalence and severity in Canada, with changing causes often remaining unknown in clinical practice. Physicians noted declining incidence and evolving triggers for this inflammatory condition.

Area of Science:

  • Rheumatology
  • Immunology
  • Epidemiology

Background:

  • Reactive arthritis (ReA) is a form of inflammatory arthritis.
  • Its prevalence and causative agents are subject to evolving trends.

Purpose of the Study:

  • To characterize Canadian rheumatologists' perspectives on the changing trends of reactive arthritis.
  • To understand current opinions on ReA's prevalence, causes, and treatment.

Main Methods:

  • A survey was distributed to 548 members of the Canadian Rheumatology Association.
  • 37 questions addressed demographics, practice setting, and views on ReA; 66 surveys were fully completed.

Main Results:

  • Nearly half of respondents perceived a decline in ReA incidence, with changing causative agents.
  • Unknown organisms, STIs, and GI infections were cited as common causes; full triad ReA correlated with recurrence.
  • Investigations included inflammatory markers, HLA-B27, and pathogen testing; treatments involved NSAIDs, injections, DMARDs, and TNF inhibitors.

Conclusions:

  • Reactive arthritis may be decreasing in frequency and severity in Canada.
  • Potential factors include reduced foodborne illness, improved water quality, and prompt STI treatment.
  • The causal organism in ReA often remains unidentified in clinical settings.
