BackgroundMonitoring the blood concentrations of antipsychotic drugs and their metabolites can guide the adjustment of clinical treatment plans， improving therapeutic efficacy while reducing adverse effects. However， there is currently a lack of a method that can accurately and efficiently quantitatively detect multiple antipsychotic drugs and their metabolites. ObjectiveTo establish a ultra-high performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS） method for the simultaneous identification and quantitation of 12 antipsychotic drugs and their main metabolites in human serum. MethodsUsing UPLC-MS/MS technology， protein precipitation method was employed for sample pretreatment. An Agela Technologies Durashell C₈ chromatographic column （50 mm×3.0 mm， 5 μm） was selected for chromatographic separation with gradient elution. The flow rate was 0.4 mL/min， and the total analysis time was 5 minutes. The column temperature was 40℃. The mass spectrometry detection was carried out in the multiple reaction monitoring （MRM） mode， and the isotope internal standard method was used for quantification. ResultsThe relative standard deviation （RSD） of the internal standard normalization matrix effect factor for 12 antipsychotic drugs and their main metabolites at low and high quality concentrations was all less than 15%. The extraction recovery rate was 85% to 115%. They showed good linear relationships within their respective standard curve ranges （r>0.995）. At low， medium， and high quality concentrations， the accuracy was 85.24% to 114.71%， and the RSD of intra-batch and inter-batch precision was all ≤14.15%， with good stability. ConclusionAll the analytical performance indicators of this method meet the verification requirements， providing an analytical means for the quantitative detection of antipsychotic drugs and their main metabolites in human serum. ［Funded by The Third Batch of Science and Technology Projects in Chaozhou City in 2023 （number， 202303GY02）］

Purpose: This study aimed to investigate the potential association between thyroid disorders and breast cancer (BC) risk in a cohort of Korean women. Materials and Methods: Data for this retrospective cohort study were obtained from the Korean National Health Insurance database, including all women aged ≥ 40 who underwent BC screening from 2009 to 2010 in Korea. Thyroid disorders were identified using medical records from 2009 to 2010 and extracted using the International Classification of Diseases, 10th revision (ICD-10) codes for thyroid nodules, hypothyroidism, and hyperthyroidism. BC cases were defined using the ICD-10 codes and tracked until December 2021. A Cox regression model was used to evaluate the association between thyroid disorders and the risk of BC. Additionally, we evaluated the association between well-known risk factors of BC and thyroid disorders using logistic regression analysis. Results: Among 5,051,633 women, the mean±standard deviation age was 55.2±10.7 years, and the median follow-up was 11.6 years, with 87,784 BC cases recorded. The proportions of patients with thyroid nodules, hypothyroidism, and hyperthyroidism were 2.5%, 1.8%, and 0.9%, respectively. The hazard ratio for BC risk associated with thyroid nodules was 1.16 (95% confidence interval [CI], 1.11 to 1.20), for hypothyroidism was 0.98 (95% CI, 0.93 to 1.03), and for hyperthyroidism was 1.13 (95% CI, 1.06 to 1.21). In both premenopausal and postmenopausal women, an increased risk of BC was significantly associated with thyroid nodules (adjusted hazard ratio [aHR], 1.16 and 1.13) and hyperthyroidism (aHR, 1.11 and 1.16). History of benign breast disease, oral contraceptive use, breastfeeding, menopausal status, and hormone replacement therapy were associated with thyroid nodules and hyperthyroidism. Conclusion Our findings suggest an increased risk of BC in women with a history of thyroid nodules and hyperthyroidism, whereas no such association was found in women with hypothyroidism.

OBJECTIVE: Asthma imposes a significant global health burden. This study examines changes in the asthma-related disease burden from 1990 to 2021 and projects future burdens for 2050 under different scenarios. METHODS: Using data from the Global Burden of Disease 2021 study, we analyzed asthma incidence, prevalence, mortality, and disability-adjusted life years (DALYs) from 1990 to 2021. We projected the disease burden for 2050 based on current trends and hypothetical scenarios in which all risk factors are controlled. Temporal trends in age-standardized incidence, prevalence, mortality, and DALY rates were explored using Annual Percent Change. RESULTS: In 2021, the age-standardized rates for asthma incidence, prevalence, mortality, and DALYs in China were 364.17 per 100,000 (95% uncertainty interval [ UI]: 283.22-494.10), 1,956.49 per 100,000 (95% UI: 1,566.68-2,491.87), 1.47 per 100,000 (95% UI: 1.15-1.79), and 103.76 per 100,000 (95% UI: 72.50-145.46), respectively. A higher disease burden was observed among Chinese men and individuals aged 70 years or older. Compared to the current trend, a combined scenario involving improvements in environmental factors, behavioral and metabolic health, child nutrition, and vaccination resulted in a greater reduction in the disease burden caused by asthma. CONCLUSION Addressing modifiable risk factors is essential for further reducing the asthma-related disease burden.

STRESS IN RELATIONSHIP WITH BURNOUT DUE TO COVID-19: THE MODERATING ROLE OF COPING STRATEGIES This study investigates the relationship between stress and burnout related to the COVID-19 pandemic, focusing on the moderating influence of positive and negative coping strategies. In a cross-sectional survey involving 3,664 Vietnamese citizens aged 18 and above, the research explores the dynamics of stress and burnout symptoms associated with the ongoing pandemic. The results reveal a negative impact of stress symptoms on COVID-19-related burnout among the population. Notably, both positive and negative coping strategies are identified as significant moderators in the interplay between stress and burnout. This suggests that individuals’ coping mechanisms influence the severity of stress and burnout experienced in dealing with COVID-19 challenges. These findings contribute to the foundational understanding of the stress-burnout relationship during the pandemic and provide essential insights for interventions. By recognizing the moderating role of coping strategies, this study lays the groundwork for strategies aimed at enhancing individuals’ coping abilities, ultimately reducing stress and burnout levels. These insights hold the potential to assist individuals in adapting more effectively to the challenges posed by the COVID-19 pandemic, fostering improved mental well-being in the face of ongoing uncertainties.
