Diagnosis, Treatment, and Follow-Up of Giant-Cell Arteritis: A Retrospective Multicenter Study.

BACKGROUND AND PURPOSE: Giant-cell arteritis (GCA) is the most common type of vasculitis in the elderly and is associated with high risks of visual loss and recurrence. Owing to its rarity in Asian populations, the current clinical interventions for these patients are not well known. Here we aimed to characterize the current management status of patients with GCA using Korean multicenter data. METHODS: This retrospective study analyzed medical records of patients with GCA at six Korean university hospitals from February 2009 to November 2022. GCA had originally been diagnosed based on the 1990 American College of Rheumatology (ACR) criteria, and cases were selected for inclusion in this study based on the 2022 ACR/European Alliance of Associations for Rheumatology criteria. We evaluated treatments, follow-up periods, and outcomes (relapse, remission, and adverse drug reactions) in patients with GCA with or without arteritic anterior ischemic optic neuropathy (AAION). RESULTS: This study analyzed 18 patients with a median age of 75.5 years that included 12 females (66.7%). Seven patients (38.8%) had AAION. All patients initially received prednisolone treatment, while four (22.2%) underwent adjuvant treatment with methotrexate and azathioprine during prednisolone tapering. During the median follow-up of 3.5 months (interquartile range: 2.0-23.2 months), 4 patients (22.2%) had prednisolone-related adverse reactions, 2 (11.1%) relapsed, and 13 (72.3%) dropped out. Nine patients (50.0%) experienced remission, with this being sustained in four (36.4%). CONCLUSIONS: This study observed high dropout rates and short follow-ups. Adverse effects of prednisolone were common, and relapses occurred in approximately one-tenth of Korean patients with GCA. Thus, optimizing GCA treatment necessitates regular monitoring and long-term follow-up.

Clinical and Radiological Features of Korean Patients With Anti-HMGCR Myopathy.

BACKGROUND AND PURPOSE: To understand the characteristics of Korean patients with anti-3-hydroxy-3-methylglutaryl-coenxyme A reductase (HMGCR) myopathy, we measured anti-HMGCR antibodies and analyzed the clinical, radiological, and pathological features of patients with anti-HMGCR myopathy. METHODS: We measured titers of anti-HMGCR antibodies in the sera of 99 patients with inflammatory myopathy, 36 patients with genetic myopathy, and 63 healthy subjects using an enzyme-linked immunosorbent assay. We tested 16 myositis-specific autoantibodies (MSAs) in all patients with anti-HMGCR myopathy. RESULTS: Positivity for the anti-HMGCR antibody was observed in 17 (4 males and 13 females) of 99 patients with inflammatory myopathy. The median age at symptom onset was 60 years. Ten (59%) of the patients with anti-HMGCR positivity had taken statins. The titer of anti-HMGCR antibodies was significantly higher in the statin-naïve group (median=230 U/mL, interquartile range=170-443 U/mL) than in the statin-exposed group (median=178 U/mL, interquartile range=105-210 U/mL, p=0.045). The most common symptom was proximal muscle weakness in 15 patients (88%), followed by myalgia in 9 (53%), neck weakness in 4 (24%), dysphagia in 3 (18%), and skin lesions in 2 (12%). The median titer of anti-HMGCR antibody was 202 U/mL. We found eight different MSAs in nine (53%) patients. The median disease duration from symptom onset to diagnosis was significantly shorter in the MSA-positive group than in the MSA-negative group (p=0.027). CONCLUSIONS: Our study was the first to measure anti-HMGCR antibodies in inflammatory myopathy. It has provided new findings, including the suggestion of the coexistence of other MSAs in Korean patients.

A 'health message' on sustainable physical and mental health for the prolonged COVID-19 and other pandemics.

The world has been living with another pandemic physical inactivity (PI) and sedentary behavior (SB) and of other nature for years. As social measures to prevent the spread of COVID-19 have been strengthened, the physical activity (PA) barrier has been hit and the PI/SB pandemic has been exacerbated, and in the current situation, triggered by its prolonged period, it is emerging as a problem to be considered in order to combat the PI/SB pandemic through PA and to maintain continuous physical and mental health. This review aims to summarize existing and recent studies on the effects of PA/SB on physical and mental health in preparation for the context of prolonged COVID-19 and provides an easy and fun way to motivate, access PA, and PA recommendations for maintaining physical and mental health. We performed search strategies on PubMed, Medline, Scopus, and Google Scholar databases, and used a literature review of the current available literature on the COVID-19 and the effects of PI, SB, and PA on physical and mental health. The clinical relevance of this review shows that integrating PA into daily life and reducing prolonged sitting time is an important strategy for continuing a healthy life physically and mentally. As a result, for those who have not yet incorporated exercise as part of their daily routine, fun and easy access to PA suggests that in the long run, may be an opportunity to implement newer habits. In addition, in an emergency such as the COVID-19 quarantine period or other pandemics, it is essential for one to maintain health through PA at home, and underscore the 'health message' of the current review that reducing SB, progressively increasing PA, and doing more PA regularly in the current context prolonged COVID-19 can bring significant benefits to long-term habits and physical and mental health.

BACKGROUND: Based on the analysis results that can further enhance organizational satisfaction and response to changes in the employment environment of cosmetic employees and workers through organizational commitment and turnover intention of cosmetic. OBJECTIVES: This research paper empirically analyzed changes in employment environment due to coronavirus disease-19 (COVID-19) pandemic and 4th industrial revolution and the effect of employees and job satisfaction on turnover intention in the cosmetic industry, and sought measures necessary for conflict management in industrial sites. METHODS: A self-report questionnaire was conducted on 508 cosmetic implementers. Statistical processing of the data collected by the data analysis method was analyzed using the Statistical Package for Social Science (SPSS) WIN23.0 statistical package program through data coding and data organizing process. RESULTS: Changes in the employment environment were found to have a significant effect on job satisfaction (t = -11.728, p < 0.05). Changes in the employment environment were found to have a significant effect on organizational commitment, which is a dependent variable (t = -9.476, p < 0.05). Changes in the employment environment and job satisfaction were found to have a significant effect on organizational commitment, and this regression model was found to be statistically significant (F = 67.703, p < 0.05). Job satisfaction showed a significant positive (+) effect on organizational commitment rather than the employment environment (t = 6.235, p < 0.05). As a result, it was found that the organizational commitment and job satisfaction of cosmetic employees and workers affected their turnover intentions due to changes in the employment environment due to the 4th industrial revolution and the COVID-19 pandemic. CONCLUSION: This study focused on the relationship between employment environment changes in the cosmetic industry due to the recent 4th industrial revolution and the COVID-19 pandemic, and the effects of job satisfaction and organizational commitment of cosmetic employees on turnover intention. Based on the results of the analysis that can further increase the organizational commitment and search for job satisfaction of cosmetic employers and workers, we intend to establish the identity of cosmetic industry organizations nationwide and raise community awareness.

Clinical pitfalls and serological diagnostics of MuSK myasthenia gravis.

BACKGROUND: We aimed to evaluate the diagnostic accuracy of enzyme-linked immunosorbent assay (ELISA) for anti-muscle specific tyrosine kinase (MuSK) antibody (Ab) in a large cohort of anti-acetylcholine receptor (AChR) Ab-negative generalized myasthenia gravis (MG), and also to investigate clinical contexts for the diagnosis of MuSK MG. METHODS: A retrospective study of 160 patients with a clinical suspicion of AChR Ab-negative generalized MG was performed. The serum samples were tested for anti-clustered AChR Ab by cell-based assay (CBA), anti-MuSK Ab by ELISA, CBA and/or radioimmunoprecipitation assay (RIPA). Clinical data were compared between anti-MuSK Ab-positive MG and double seronegative (AChR and MuSK) MG groups. RESULTS: After excluding non-MG and clustered AChR Ab-positive patients, we identified 89 patients as a cohort of AChR Ab-negative generalized MG. Anti-MuSK Ab was positive by ELISA in 22 (24.7%) patients. While CBA identified five additional anti-MuSK Ab-positive patients, the results of ELISA were mostly consistent with CBA and RIPA with Cohen's kappa of 0.80 and 0.90, respectively (p < 0.001). The most frequent differential diagnosis was motor neuron disease particularly of bulbar onset which showed remarkably overlapping clinical and electrophysiological features with MuSK MG at presentation. CONCLUSION: While confirming the highest sensitivity of CBA for detecting anti-MuSK Ab, our results highlight the clinical pitfalls in making a diagnosis of MuSK MG and may support a diagnostic utility of MuSK-ELISA in clinical practice.
