Electronic Journal of Differential Equations, 2016 In this article, we use critical point theory to obtain multiple periodic solutions for second-order discrete Hamiltonian systems, when the nonlinearity is partially periodic and its gradient is linearly and sublinearly bounded.

Arthritis Care &Research, EarlyView.Objective Several case reports have proposed a potential association between COVID‐19 vaccination and the subsequent development of idiopathic inflammatory myositis (IIM). This study examined prior COVID‐19 vaccination in US veterans who developed new‐onset IIM compared to those without new‐onset IIM.

Almost periodic solutions of higher order differential equations on Hilbert spaces
Electronic Journal of Differential Equations, 2010 We find necessary and sufficient conditions for the differential equation $$ u^{(n)}(t) = Au(t)+f(t), quad tin mathbb{R} $$ to have a unique almost periodic solution. Some applications are also given.

Retractions in Rheumatology: Trends, Causes, and Implications for Research Integrity
Arthritis Care &Research, EarlyView.Objective We aimed to describe the trends and main reasons for study retraction in rheumatology literature. Methods We reviewed the Retraction Watch database to identify retracted articles in rheumatology. We recorded the main study characteristics, authors’ countries, reasons for retraction, time from publication to retraction, and trends over time ...

Immune Checkpoint Inhibitor–Related Myositis and Associated Triad Overlap Syndrome
Arthritis Care &Research, EarlyView.Objective Immune checkpoint inhibitor (ICI) myositis is a rare but a highly morbid condition, particularly with the ICI myositis triad syndrome of myositis, myocarditis, and myasthenia gravis. We report the clinical characteristics of ICI myositis and all‐cause mortality in these patients.

Arthritis Care &Research, EarlyView.Objective The American College of Rheumatology recommends HLA‐B*58:01 allele testing before the initiation of allopurinol, specifically among Asian and African American/Black patients, due to their increased risk for severe hypersensitivity reactions. However, testing rates remain low at many health care facilities.

The Sarkovskii order for periodic continua II
Topology and its Applications, 2007 \textit{A. N. Sharkovskij} [Ukr. Mat. Zh. 16, 61--71 (1964; Zbl 0122.17504)] proved that if \(p \prec q\) according to the following ordering of the positive integers, then for any map of the real line to itself with a periodic point of period \(p\), there exists a periodic point of period \(q\).

Arthritis Care &Research, EarlyView.Objective We examined whether 18 months of strength training in individuals with knee varus alignment and medial tibiofemoral osteoarthritis (OA) reduced knee joint loads during walking compared to an attention control group. Methods This study was a secondary analysis of a randomized clinical trial that compared the effects of strength training to a ...
