Background: While vaccination remains crucial in mitigating the impact of the COVID-19 pandemic, several ocular adverse events has been reported, including Acute Zonal Occult Outer Retinopathy (AZOOR) complex. Case presentation: A 31-year-old female presented declined best corrected visual acuity (BCVA) and flashes in both eyes three days following second recombinant mRNA COVID-19 vaccine (Moderna). Fundus autofluorescence (FAF) illustrated speckled hyper-AF lesions surrounding right eye torpedo maculopathy site and hyper-AF lesions in the left macula. The spectral-domain optical coherence tomography delineated inner and outer segment (IS/OS) line disruption; hyperreflective deposits in the outer nuclear layer (ONL); and undetectable interdigitation zone (IDZ). Her BCVA further declined after 3-month observation, thus she received 8-month oral prednisolone and mycophenolate mofetil treatment. Her BCVA recovered; the hype-AF lesions resolved; and the IS/OS line and ONL resumed. Conclusions: We present a rare case of AZOOR complex following COVID-19 vaccination inciting from torpedo retinopathy where outer-retinal barrier breaks down. [ABSTRACT FROM AUTHOR]

Background: Detecting vertebral structural damage in patients with ankylosing spondylitis (AS) is crucial for understanding disease progression and in research settings. Objectives: This study aimed to use deep learning to score the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) using lateral X-ray images of the cervical and lumbar spine in patients with AS in Asian populations. Design: A deep learning model was developed to automate the scoring of mSASSS based on X-ray images. Methods: We enrolled patients with AS at a tertiary medical center in Taiwan from August 1, 2001 to December 30, 2020. A localization module was used to locate the vertebral bodies in the images of the cervical and lumbar spine. Images were then extracted from these localized points and fed into a classification module to determine whether common lesions of AS were present. The scores of each localized point were calculated based on the presence of these lesions and summed to obtain the total mSASSS score. The performance of the model was evaluated on both validation set and testing set. Results: This study reviewed X-ray image data from 554 patients diagnosed with AS, which were then annotated by 3 medical experts for structural changes. The accuracy for judging various structural changes in the validation set ranged from 0.886 to 0.985, whereas the accuracy for scoring the single vertebral corner in the test set was 0.865. Conclusion: This study demonstrated a well-trained deep learning model of mSASSS scoring for detecting the vertebral structural damage in patients with AS at an accuracy rate of 86.5%. This artificial intelligence model would provide real-time mSASSS assessment for physicians to help better assist in radiographic status evaluation with minimal human errors. Furthermore, it can assist in a research setting by offering a consistent and objective method of scoring, which could enhance the reproducibility and reliability of clinical studies.

Background: Patients with ankylosing spondylitis (AS) suffer from impaired physical activity and are prone to motor vehicle accidents (MVA), but definite instruction regarding the relationship between disease evolvement and MVA and potential risk factors is lacking. Objectives: To explore the risk factors and their impact on recorded MVA with profound injuries in AS patients with prescriptions. Design: Nationwide, population-based, matched retrospective cohort study. Methods: Using Taiwanese administrative healthcare databases, with available claims data from 2003 to 2013, we selected 30,911 newly diagnosed adult AS patients with concurrent prescriptions from 2006 to 2012 as AS patients, along with 309,110 non-AS individuals as the control group, matched in gender, age at index date and year of the index date. The risk of recorded MVA with profound injuries was compared between the two groups in terms of incidence rate ratio (IRR) and log-rank test p -value. Using Cox regression analysis, we studied associations between the risk and AS diagnosis. Results: The risk of recorded MVA with profound injuries in AS patients was significantly higher than in non-AS individuals, specifically 2 years after AS diagnosis (IRR, 2.00; 95% confidence interval (CI), 1.42–2.81). For patients with follow-up periods >2 years, the adjusted risk was positively associated with suburban residence (adjusted hazard ratio (aHR), 2.18; 95% CI, 1.55–3.06), rural residence (aHR, 1.89; 95% CI, 1.27–2.80), lower insured income (aHR, 1.35; 95% CI, 1.01–1.81) and recorded MVA with profound injuries before AS diagnosis (aHR, 6.16; 95% CI, 2.53–14.96). AS diagnosis (aHR, 1.81; 95% CI, 1.27–2.59) and frequency of ambulatory visits (aHR, 1.01; 95% CI, 1.004-–1.02) were specific associated factors for them compared with those with follow-up periods ⩽2 years. Conclusion: For adult AS patients in Taiwan, factors such as AS disease evolution and frequent ambulatory visits for disease control in the second year of the disease course may significantly increase the risk of recorded MVA with profound injuries beyond 2 years after AS diagnosis.

Primary Sjogren's syndrome (pSS) is often concomitant with fibromyalgia (FM). Salivary gland sonography aids in the diagnosis of pSS. We aimed to discover, in primary FM patients, the presence of pSS in undiagnosed patients through salivary gland sonography. We prospectively recruited 42 primary FM patients. FM symptoms were evaluated based on the revised Fibromyalgia Impact Questionnaire (FIQR). Salivary gland sonography was performed. Patients with positive findings underwent salivary gland biopsy. Comparisons were undertaken using the Mann–Whitney U tests and Chi-squared test. In primary FM patients, the prevalence of dry eye was 83%, and dry mouth was 90%. The salivary gland sonographic score did not differ between patients with and without dry eye/mouth. One patient with a positive finding at salivary gland sonography had a positive result of salivary gland biopsy. In the other four patients who received salivary gland biopsy, despite negative findings in salivary gland sonography, only one had a positive result of salivary gland biopsy. To be noted, scores evaluated by salivary gland sonography were negatively associated with levels of pain (rho = −0.360, p= 0.023) and levels of sleep quality (rho = −0.447, p = 0.004). Our pilot study demonstrated the potential of salivary gland biopsy in detecting undiagnosed pSS in primary FM patients. [ABSTRACT FROM AUTHOR]

Objective The objective of this study was to assess the incidence and risk factors of major adverse cardiovascular events (MACEs) in patients with systemic sclerosis (SSc). Methods We conducted a nationwide, population-based, cohort study using Taiwan's National Health Insurance Research Database. We performed propensity score matching (PSM) using a 1:2 ratio, resulting in inclusion of 1379 patients with SSc and 2758 non-SSc individuals in the analysis. We assessed the association between SSc and MACEs, using the multivariable Cox proportional hazard regression model with adjustment of time-dependent covariates, and investigated risk factors for MACEs in patients with SSc, shown as adjusted hazard ratios (aHRs) with 95% CIs. Results SSc was not significantly associated with the risk of MACEs (aHR 1.04; 95% CI 0.77–1.42). Nevertheless, SSc was associated with increased risk of myocardial infarction [incidence rate ratio (IRR) 1.76; 95% CI 1.08–2.86] and peripheral arterial occlusion disease (IRR 3.67; 95% CI 2.84–4.74) but not of ischaemic stroke (IRR 0.89; 95% CI 0.61–1.29). Factors independently associated with MACEs in SSc patients included age (aHR 1.02), male gender (aHR 2.01), living in a suburban area (aHR 2.09), living in a rural area (aHR 3.00), valvular heart disease (aHR 4.26), RA (aHR 2.14), use of clopidogrel (aHR 26.65), and use of aspirin (aHR 5.31). Conclusions The risk of MACEs was not significantly increased in Taiwanese patients with SSc, and our investigation effectively identified the factors independently associated with MACEs in SSc patients. Additionally, patients with SSc exhibited higher risks of myocardial infarction and peripheral arterial occlusion disease but not of ischaemic stroke. [ABSTRACT FROM AUTHOR]
