A Lifestyle Management for Arthritis Group education intervention for people with inflammatory and degenerative arthritis: An observational study.

Background: Occupational therapy self-management groups aim to assist individuals to incorporate health-promoting behaviours and management strategies into their daily routines to promote wellbeing. The Lifestyle Management for Arthritis Group (LMAG) is a 2-h-long, occupational therapy educational-behavioural group intervention adapted from the evidence-based Lifestyle Management for Arthritis Programme (Hammond & Rayner, 2013) and was delivered to inpatients with inflammatory and degenerative arthritis separately.

Aim: The aim of this study was to evaluate the effectiveness of this intervention in an inpatient Rheumatology Rehabilitation setting.

Protonated benzofuran, anthracene, naphthalene, benzene, ethene, and ethyne: measurements and estimates of pK(a) and pK(R).

Aqueous solvolyses of acyl derivatives of hydrates (water adducts) of anthracene and benzofuran yield carbocations which undergo competitive deprotonation to form the aromatic molecules and nucleophilic reaction with water to give the aromatic hydrates. Trapping experiments with azide ions yield rate constants k(p) for the deprotonation and k(H2O) for the nucleophilic reaction based on the "azide clock". Combining these with rate constants for (a) the H(+)-catalyzed reaction of the hydrate to form the carbocation and (b) hydrogen isotope exchange of the aromatic molecule (from the literature) yields pK(R) = -6.
