- Comorbidities are frequent in psoriatic arthritis (PsA) but it is not known how they differ from other high comorbidity burden diseases like rheumatoid arthritis (RA) and diabetes mellitus (DM).Objectives:To compare the prevalence of comorbidities in PsA vs. RA and DM patients.Methods:215 PsA patients were age/gender-matched with 215 RA and 215 DM patients from two tertiary hospitals. Prevalence of comorbidities (hypertension, current smoking, hyperlipidemia, obesity (BMI≥30), coronary disease [CD], stroke, MACE [combined CD and stroke], depression, osteoporosis, history of malignancies) were compared across the three groups. Within PsA group, associations between comorbidities and demographic and clinical features (e.g entheitis), including PsA phenotypes (RA-like vs oligoarthritis pattern and Axial-involvment vs Non-Axial-involvement) were assessed.Results:Hyperlipidaemia, obesity and depression were more frequent in PsA vs. RA. Depression and osteoporosis were more common in PsA vs DM. In contrast, hypertension was more frequent in DM. All other comorbidities, including frequency of stroke, CD and major adverse cardiovascular events did not differ between groups. Results remain unchanged after adjustments (Table 1).Table 1.Comparison of comorbidities between psoriatic arthritis (PsA), rheumatoid (RA) arthritis and Diabetes mellitus (DM) patients.

MACEs in PsA, were associated with male gender (p=0.03), older age (p=0.0002), dyslipidaemia (p=0.003) and hypertension (p<0.0001). No differences were found between different phenotypes of PsA.Conclusion:PsA patients had higher BMI and hyperlipidaemia compared to RA but not to DM. MACE is comparable between PsA and RA or DM, while depression is more common in PsA. Taking into account certain risk factors, screening for and management of comorbidities in PsA is important in the clinical setting.Disclosure of Interests:George E.

- Structural and morphological control of crystalline nanoparticles is crucial in the field of heterogeneous catalysis and the development of reaction specific catalysts. To achieve this, colloidal chemistry methods are combined with ab initio calculations in order to define the reaction parameters, which drive chemical reactions to the desired crystal nucleation and growth path. Key in this procedure is the experimental verification of the predicted crystal facets and their corresponding electronic structure, which in case of nanostructured materials becomes extremely difficult. Here, by employing P-31 solid-state nuclear magnetic resonance aided by advanced density functional theory calculations to obtain and assign the Knight shifts, we succeed in determining the crystal and electronic structure of the terminating surfaces of ultrafine Ni2P nanoparticles at atomic scale resolution. Our work highlights the potential of ssNMR nanocrystallography as a unique tool in the emerging field of facet-engineered nanocatalysts. Structural and morphological control of crystalline nanoparticles is crucial in heterogeneous catalysis. Applying DFT-assisted solid-state NMR spectroscopy, we determine the surface crystal and electronic structure of Ni2P nanoparticles, unveiling NMR nanocrystallography as an emerging tool in facet-engineered nanocatalysts.
