        Multimorbidity Pattern and Risk for Mortality Among Patients With Dementia: A Nationwide Cohort Study Using Latent Class Analysis

        Che-Sheng Chu,Shu-Li Cheng,Ya-Mei Bai,Tung-Ping Su,Shih-Jen Tsai,Tzeng-Ji Chen,Fu-Chi Yang,Mu-Hong Chen,Chih-Sung Liang 대한신경정신의학회 2023 PSYCHIATRY INVESTIGATION Vol.20 No.9

        Objective Individuals with dementia are at a substantially elevated risk for mortality; however, few studies have examined multimorbidity patterns and determined the inter-relationship between these comorbidities in predicting mortality risk.Methods This is a prospective cohort study. Data from 6,556 patients who were diagnosed with dementia between 1997 and 2012 using the Taiwan National Health Insurance Research Database were analyzed. Latent class analysis was performed using 16 common chronic conditions to identify mortality risk among potentially different latent classes. Logistic regression was performed to determine the adjusted association of the determined latent classes with the 5-year mortality rate.Results With adjustment for age, a three-class model was identified, with 42.7% of participants classified as “low comorbidity class (cluster 1)”, 44.2% as “cardiometabolic multimorbidity class (cluster 2)”, and 13.1% as “FRINGED class (cluster 3, characterized by FRacture, Infection, NasoGastric feeding, and bleEDing over upper gastrointestinal tract).” The incidence of 5-year mortality was 17.6% in cluster 1, 26.7% in cluster 2, and 59.6% in cluster 3. Compared with cluster 1, the odds ratio for mortality was 9.828 (95% confidence interval [CI]=6.708–14.401; p<0.001) in cluster 2 and 1.582 (95% CI=1.281–1.953; p<0.001) in cluster 3.Conclusion Among patients with dementia, the risk for 5-year mortality was highest in the subpopulation characterized by fracture, urinary and pulmonary infection, upper gastrointestinal bleeding, and nasogastric intubation, rather than cancer or cardiometabolic comorbidities. These findings may improve decision-making and advance care planning for patients with dementia.

      • Decreased Expression of FADS1 Predicts a Poor Prognosis in Patients with Esophageal Squamous Cell Carcinoma

        Du, Yong,Yan, Shu-Mei,Gu, Wan-Yi,He, Fan,Huang, Li-Yun,Li, Mei,Yuan, Yan,Chen, Ren-Hui,Zhong, Qian,Li, Man-Zhi,Li, Yong,Zeng, Mu-Sheng Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.12

        FADS1 (fatty acid desaturase 1) plays a crucial role in fatty acid metabolism, and it was recently reported to be involved in tumorigenesis. However, the role of FADS1 expression in esophageal squamous cell carcinoma (ESCC) remains unknown. In the current study, we investigated the expression and clinical pathologic and prognostic significance of FADS1 in ESCC. Immunohistochemical analyses revealed that 58.2% (146/251) of the ESCC tissues had low levels of FADS1 expression, whereas 41.8% (105/251) exhibited high levels of FADS1 expression. In positive cases, FADS1 expression was detected in the cytoplasm of cells. Correlation analyses demonstrated that FADS1 expression was significantly correlated with tumor location (p=0.025) but not with age, gender, histological grade, tumor status, nodal status or TNM staging. Furthermore, patients with tumors expressing high levels of FADS1had a longer disease-free survival time (p<0.001) and overall survival time (p <0.001). Univariate and multivariate analyses revealed that, along with nodal status, FADS1 expression was an independent and significant predictive factor (p<0.001). In conclusion, our study suggested that FADS1 might be a valuable biomarker and potential therapeutic target for ESCC.

      • Safety and Efficacy of Elbasvir/Grazoprevir in Asian Participants with Hepatitis C Virus Genotypes 1 and 4 Infection

        Aims: Clinical experience with direct-acting antiviral treatments for hepatitis C virus (HCV) infection is emerging in the Asia-Pacific region. We conducted an integrated analysis of the safety and efficacy of elbasvir (EBR)/grazoprevir (GZR) in self-identified Asian participants who were enrolled in 11 EBR/GZR phase 2/3 studies. Methods: All participants received EBR/GZR 50 mg/100 mg alone for 12 weeks or in combination with ribavirin (RBV) for 16 weeks. The primary endpoint of all studies was sustained virologic response (HCV RNA < 15 IU/mL) 12 weeks after end of therapy (SVR12). Results: A total of 780 Asian participants with HCV GT1 or 4 infection were included (GT1b, n=715; GT1non-b, n=63; GT4, n=2). Most participants were enrolled from Japan (n=366, 46.9%), mainland China (n=146, 18.7%), Taiwan (n=109, 14.0%) and South Korea (n=90, 11.5%). Overall, 12.4% of participants had cirrhosis, and 20.4% were treatment-experienced. SVR12 was achieved by 756/780 (96.9%, 95% CI 95.5-98.0) of all Asian participants, including 748/772 (96.9%, 95% CI 95.4- 98.0) who received EBR/GZR for 12 weeks and 8/8 (100%, 95% CI 63.1-100.0) who received EBR/GZR + RBV for 16 weeks. The frequency of safety events among Asian participants was: any adverse event (AE), 58.1% (453/780), drug-related AEs, 23.6% (184/780), serious AEs, 2.6% (20/780), and discontinuation due to an AE, 0.9% (7/780). Fifteen participants (1.9%) had elevated ALT/AST levels that met the criteria for an event of clinical interest (ALT/AST >3× baseline and >100 U/L), 3 of whom discontinued treatment. The efficacy and safety profile of EBR/GZR was comparable to that observed among non-Asians. Conclusions: The combination of EBR/GZR was safe and highly effective in this large population of Asian participants with primarily HCV GT1b infection. Late transaminase elevations were reported in approximately 2% of participants, which is consistent with the safety profile of EBR/GZR in non-Asians.
