Incidence of COVID-19 in a cohort of adult and paediatric patients with rheumatic diseases treated with targeted biologic and synthetic disease-modifying anti-rheumatic drugs.
To investigate the incidence of COVID-19 in a cohort of adult and paediatric patients with rheumatic diseases receiving targeted biologic and synthetic disease modifying anti-rheumatic drugs (tDMARDs) and to explore the possible effect of these treatments in the clinical expression of COVID-19. ⋯ Adult and paediatric patients with rheumatic diseases on tDMARDs do not seem to present a higher risk of COVID-19 or a more severe disease outcome when compared to general population.

Does type 2 diabetes increase the risk of musculoskeletal pain? Cross-sectional and longitudinal analyses of UK biobank data.
We investigated cross-sectional associations and whether type 2 diabetes increases the risk of musculoskeletal pain after adjusting for the presence of important comorbidities. ⋯ People with type 2 diabetes are more likely to report musculoskeletal pain in shoulder/neck, knee or hip. In addition, people with type 2 diabetes, particularly women, are more likely to present with a future episode of neck/shoulder pain. This study highlights the need to consider musculoskeletal screening among patients with diabetes and also serves as a stimulus for investigation of the mechanisms that explain the relationship between musculoskeletal pain and type 2 diabetes; with a view to prevention or improving future treatment.

Visual and semiquantitative assessment of cranial artery inflammation with FDG-PET/CT in giant cell arteritis.
Assessing cranial artery inflammation plays an important role in the diagnosis of cranial giant cell arteritis (C-GCA). However, current diagnostic tests are limited. The use of fluorine-18-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT imaging is an established tool for assessing large vessel inflammation but is currently not used for assessment of the cranial arteries. This study aimed to evaluate the accuracy of FDG-PET/CT in the diagnosis of biopsy proven C-GCA and its relation to clinical presentation. ⋯ FDG-PET/CT can reliably diagnose C-GCA by assessing cranial artery inflammation using SUVmax. Extending the use of FDG-PET/CT to include assessment of the cranial arteries may improve its diagnostic value in GCA and provide a suitable alternative to TAB. Moderate agreement between visual and semiquantitative assessment methods suggest diagnostic accuracy may be improved by further standardisation.

COVID-19 in rheumatic disease patients on immunosuppressive agents.
To analyze clinical characteristics and outcome of COVID-19 patients with underlying rheumatic diseases (RD) on immunosuppressive agents. ⋯ There were 4 COVID-19 inpatients with RD from our hospital, and the mean age was 57 ± 21 years. Two patients had a mild infection, and 2 developed severe COVID-19 related respiratory complications, including 1 patient on secukinumab requiring mechanical ventilation and 1 patient on rituximab developing viral pneumonia requiring supplemental oxygenation. All 4 patients had elevated acute phase reactants, 2 patients had mild COVID-19 with lymphopenia, and 2 patients had severe COVID-19 with normal lymphocyte counts, and high levels of IL-6. None of the patients exhibited an exacerbation of their underlying RD. In the literature, there were 9 studies of COVID-19 involving 197 cases of various inflammatory RD. Most patients were on DMARDs or biologics, of which TNFα inhibitors were most frequently used. Two tocilizumab users had a mild infection. Two patients were on rituximab with 1 severe COVID-19 requiring mechanical ventilation. Six patients were on secukinumab with 1 hospitalization. Of the total 201 cases, 12 died, with an estimated mortality of 5.9% CONCLUSION: Patients with RD are susceptible to COVID-19. Various DMARDs or biologics may affect the viral disease course differently. Patients on hydroxychloroquine, TNFα antagonists or tocilizumab may have a mild viral illness. Rituximab or secukinumab could worsen the viral disease. Further study is warranted.

Randomized Controlled TrialOnset and maintenance of efficacy of subcutaneous tanezumab in patients with moderate to severe osteoarthritis of the knee or hip: A 16-week dose-titration study.
To examine the onset and maintenance of efficacy of subcutaneous tanezumab for pain relief and functional improvement in difficult-to-treat patients with moderate-to-severe osteoarthritis (OA) in a 16-week dose-titration study (NCT02697773). ⋯ Subcutaneous tanezumab provided statistically significant improvements compared with placebo in average daily index joint pain within the first week and WOMAC Pain and Physical Function (week 2) that were generally maintained throughout the 16-week treatment period. Tanezumab 5 mg provided only modest additional efficacy over tanezumab 2.5 mg.
