ABSTRACT
Background and Objectives: Multiple hyaluronic acid (HA) products were approved and marketed to manage osteoarthritis (OA). Although these products are widely prescribed by orthopedic surgeons to manage OA, especially knee OA, the therapeutic value of these products is highly uncertain. Few studies with significant limitations in their designs have indicated positive outcomes among OA patients treated with HA; however, their results were inconclusive. Thus, we aimed to explore the therapeutic value of different HA products in alleviating knee OA pain and improving patients' physical function from the orthopedic surgeons' perspective. Materials and Methods: This was a questionnaire-based cross-sectional study in which practicing orthopedic surgeons in two countries (e.g., Saudi Arabia and Jordan) were invited to participate. The 10-item, newly developed questionnaire inquired about the respondents' sociodemographic characteristics (e.g., age, gender, country, years of experience), and their opinions regarding the efficacy of HA products in the management of OA (e.g., efficacy in improving mobility and alleviating pain). Results: Out of the 200 orthopedic surgeons who were invited to participate, 122 (61%) filled out the questionnaire. Most of the respondents were from Saudi Arabia (58%), aged 35 to 55 years (68%), had at least 10 years of experience (69%), and male (98%). About 80% of the respondents reported prescribing HA, such as Hyalgan®, Orthovisc®, Hyalubrix®, and Crespine Gel®. About 66% of the respondents believed that HA was moderately to highly effective in managing knee OA, and 34% believed that HA was either ineffective or mildly effective. Pain at the site of injection (44.3%) and rash or local skin reactions (22.1%) were the most commonly reported adverse events. Conclusions: The variations in the formulation of different HA brands (e.g., molecular weight and cross-linking) did not seem to offer any therapeutic advantage. HA might have value in the management of knee OA; however, its value is highly uncertain and necessitates more well-designed studies to further examine its therapeutic value.

BACKGROUND: Pseudomonas aeruginosa is a leading nosocomial Gram-negative bacteria associated with prolonged hospitalization, and increased morbidity and mortality. Limited data exist regarding P. aeruginosa infection and outcome in patients managed in intensive care units (ICUs) in the Gulf countries. We aimed to determine the risk factors, antimicrobial susceptibility pattern and patient outcomes of P. aeruginosa infection in ICU. METHODS: In this matched case-control study, all P. aeruginosa infections that occurred >48 h after hospital admission between January 31st 2016 and December 31st 2018 at ICUs affiliated with King Abdulaziz Medical City, Riyadh were included. P. aeruginosa was identified using MALDI-TOF (Vitek-MS) by biomérieux, and the antimicrobial susceptibility testing was performed using an automated biomérieux VITEK®ï¸ 2 Antimicrobial Susceptibility card. RESULTS: The study included 90 cases and 90 controls. Compared with controls, cases had significantly higher mean ICU stay and higher proportions with previous history of antimicrobial therapy, coronary artery disease, malignancy, hemodialysis, previous surgery, use of central line, urethral catheterization, nasogastric tube, and tracheostomy. In a multivariate conditional logistic regression analysis, factors independently associated with P. aeruginosa infection were ICU duration [Odds Ratio (OR) 9.05, 95%CI 2.53-32.27, p = .001], previous surgery (OR = 7.33, 95%CI 1.66-32.36, p = .009), tracheostomy (OR = 11.13, 95%CI 1.05-118.59, p = .046), urethral catheterization (OR = 7.38, 95%CI 1.21-45.11, p = .030) and use of aminoglycosides (OR = 10.59, 95%CI 1.14-98.13, p = .038). Approximately 41% of P. aeruginosa isolates were resistant to imipenem, while 36.7% were multidrug-resistant. Mortality was similar in both groups: 54(60%) cases and 51(56.7%) controls; p = .650. CONCLUSIONS: The study identifies several potentially modifiable factors associated with P. aeruginosa infection in ICUs. Identification of these factors could facilitate case identification and enhance control measures.

OBJECTIVE: Our aim is to test the validity of the Psoriasis Symptom Inventory (PSI), a patient-reported outcome, to assess the psoriasis severity within the scope of rheumatology. METHODS: Within the PsA international database (PSART-ID), 571 patients had PSI, while 322 of these also showed body surface area (BSA). Correlations between PSI, BSA, and other patient- and physician-reported outcomes were investigated. RESULTS: There was a good correlation between PSI and BSA (r=0.546, p<0.001), which was even higher for mild psoriasis (BSA<3 (n=164): r=0.608, p<0.001). PSI significantly correlated with fatigue, pain, and patient and physician global parameters (p<0.001). CONCLUSION: PSI has a good correlation with other patient- and physician-reported outcomes, and our findings support its use in rheumatology practice.
ABSTRACT
OBJECTIVE: To investigate the relationship between physical examination (PE) and sonographic features of enthesitis, based on anatomical sites. METHODS: The analysis was done using merged raw data of 3 studies on 2298 entheses. RESULTS: Patients with clinical Achilles enthesitis had more abnormalities on ultrasound (US): hypoechogenicity, p < 0.001; thickening, p = 0.001; Doppler signals, p = 0.002; and erosions, p = 0.02. The patellar tendon origin also correlated with PE but distal patellar tendon insertion and plantar aponeurosis were uncoupled from the US. CONCLUSION: The relationship between clinical and sonographic findings for large entheses is dependent on the anatomical site. For the patellar tendon origin and Achilles entheses, PE is significantly linked to US findings.

Objectives: AS and PsA share clinical and immunological features centred on enthesitis. However, a strong association between PsA and preceding injury has been recognized. The aim of this study was to test the hypothesis that the entheseal damage seen by US is commoner in PsA patients than in AS patients. Methods: Seventy-nine AS and 85 PsA patients had US scans of 1640 entheses to calculate entheseal inflammation (hypoechogenicity, thickening and Doppler) and damage scores (calcifications, enthesophytes and erosions). Regression modelling was done to evaluate the effect of diagnoses on outcomes, controlling for age, gender, BMI, clinical enthesitis, HLA-B27, and anti-TNF use. Results: Both inflammation and damage scores on US were correlated with BMI (r = 0.392; r = 0.320) and age (r = 0.308; r = 0.538) (P < 0.001), and men had higher inflammation scores than women [12.3 (7.5) vs 8.9 (7.3), P = 0.001]. In multivariate analysis, despite similar (anti-TNF-treated patients) or slightly less inflammation (anti-TNF-naïve patients) in the PsA group, they had 4.22 times more US damage than their counterparts with AS. The difference was even higher in the anti-TNF-naïve patients (5.6 times). Conclusion: On US assessment, PsA patients have greater entheseal insertion damage scores compared with AS, suggesting potential differences in tissue repair, immunobiology or response to injury at insertions.

Psoriatic arthritis (PsA) may affect different joints, including the spine. The prevalence of spinal involvement is variable depending on the definition and a subset of patients have been identified in cohorts that do not have clinical features of axial disease and yet have imaging findings. Still, there is not a consensus on how and when to screen axial disease. In this study, we aimed to investigate factors associated with being underdiagnosed for axial psoriatic arthritis (axPsA) and its impacts on outcomes. Disease features and outcomes of axPsA according to the physician (n = 415) were compared with patients with imaging findings only (sacroiliitis fulfilling the modified New York criteria, n = 112), using data from a real-life PsA registry. Patients with imaging findings only were more frequently women (83/220 (37.7%) vs 29/122 (23.8%); p = 0.008). This group also had higher peripheral disease activity (imaging only vs clinical AxPsA: mean (SD) tender joint count 5.3 (6.1) vs 3.3 (4.7), swollen joint count 1.9 (2.9) vs 1.2 (2.4); p < 0.001 for both comparisons) and was less often treated using TNF inhibitors (16.1 vs 38.2%; p < 0.001) than patients who were classified as axPsA. Patient-reported outcomes were similar in both groups. PsA patients, especially women with more severe peripheral disease, have a higher risk of being underdiagnosed for axPsA. The severity of peripheral symptoms may be a risk factor to mask the spinal features of PsA.
