    Glabridin Suppresses Macrophage Activation by Lipoteichoic Acid In Vitro: The Crucial Role of MAPKs-IL-1β-iNOS Axis Signals in Peritoneal and Alveolar Macrophages

    by Shaw-Min Hou, Chun-Ming Yang, Wei-Chieh Huang, Ssu-Wei Cheng, Ting-Lin Yen, Chih-Wei Hsia, Cheng-Ying Hsieh, Chih-Hsuan Hsia

    Inflammation, a fundamental response to infection and injury, involves interactions among immune cells and signaling molecules. Dysregulated inflammation contributes to diseases such as autoimmune disorders and cancer. Interleukin-1 beta (IL-1β), produced by macrophages in response to lipoteichoic acid (LTA) from Gram-positive bacteria, is a key inflammatory mediator. Glabridin (GBD), a bioactive compound from licorice root, exhibits anti-inflammatory properties. This study investigates GBD’s effects on LTA-induced proinflammatory signaling in RAW 264.7 murine macrophages and alveolar macrophages, MH-S, focusing on IL-1β expression and signaling pathways. Cell viability assays confirmed that 20 μM GBD was non-cytotoxic. Confocal microscopy and quantitative PCR showed that GBD significantly reduced IL-1β fluorescence intensity, mRNA, and protein levels. GBD also inhibited inducible nitric oxide synthase (iNOS) expression and nitric oxide (NO) production. Further analysis revealed that GBD suppressed NF-κB p65 nuclear translocation and selectively modulated MAPK pathway activation by reducing JNK and p38 MAPK phosphorylation without affecting ERK. Studies using specific inhibitors demonstrated that IL-1β production reduction was mechanistically linked to MAPK pathway inhibition. These findings highlight GBD’s potential as a therapeutic agent for inflammatory diseases through its ability to modulate critical inflammatory mediators and signaling pathways.

    Costs and Length of Stay of Hospitalizations due to Diabetes-Related Complications

    by Ssu-Wei Cheng, Chih-Yuan Wang, Yu Ko

    Background. Diabetes mellitus (DM) has become a significant worldwide public health problem and economic burden because a great proportion of healthcare costs has been spent on the treatment of DM and its related complications. The aim of this study was to examine the costs and length of stay (LoS) of hospitalizations due to diabetes-related complications in Taiwan. Methods. This study is a retrospective claim database analysis using the Longitudinal Cohort of Diabetes Patients, with 2012 used as the base year. The hospitalization costs and LoS per admission were estimated for each complication of interest using data from the LHDB 2004 to 2012 cohorts. The presence of eight DM-related complications were identified using the ICD-9-CM codes and procedure codes. ANOVA was used to examine the relationships of diabetes duration with the LoS and costs of the complications. Results. A total of 27,473 DM patients who were hospitalized in 2012 due to one of the examined DM-related complications were identified. The most common complications that caused the hospitalizations were nonfatal stroke (34.7%) and nonfatal ischemic heart disease (IHD) (28.7%). Amputation was the complication with the longest hospital stay, with a mean±SD of 21.6±14.1 days, followed by nonfatal stroke (13.6±11.3), ulcer (12.7±11.8), and fatal IHD (12.2±13.6). The complications with the greatest hospitalization cost were fatal IHD (mean=TWD 306,209.8; median=TWD 221,417.0; 1TWD=0.034USD) and fatal myocardial infarction (mean=TWD 272,840.1; median=TWD 174,008). Conclusions. This study indicates that DM-related complications are associated with significant hospital LoS and costs. The study results could be useful for economic evaluations of diabetes treatments and the estimation of the overall economic impact of diabetes.

    Healthcare costs and utilization of diabetes-related complications in Taiwan

    by Ssu-Wei Msc Cheng, Chin-Yuan Wang, Jin-Hua Chen, Yu Ko

    To estimate the healthcare utilization and costs of major diabetes mellitus (DM)-related complications in Taiwan in the year of first occurrence and in subsequent years. This study is a retrospective claim database analysis using the longitudinal cohort of diabetes patients (LHDB) with 2012 as the base year. Occurrences of 8 DM-related complications of interest were identified using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. Annual healthcare costs and utilization of these DM-related complications in the LHDB cohorts of the years 2004 to 2009 were examined, and the generalized linear model was used to estimate annual total healthcare costs for each complication. DM patients with complications were more likely to have at least 1 emergency room (ER) visit and at least 1 hospitalization (both P < .001), and they also had more outpatient visits, higher hospitalization costs, higher outpatient costs, and higher ER costs (all P < .001) than those without. The mean annual total healthcare cost of the patients with DM-related complications was US $4189, whereas the mean annual cost of those patients without complication was $1424 (P < .001). The complications with the greatest event costs were amputation ($7877; 95% confidence interval [CI]: $6628–$9322) and fatal MI ($4067; 95% CI: $3001–$5396) while the complication with the greatest state costs was end-stage renal disease (ESRD) ($2228; 95% CI: $2155 to $2302). DM-related complications could significantly increase healthcare utilization and costs. The results of this study provide data that are useful for local economic evaluations of DM treatments.


  • Patient preferences for diabetes-related complications in Taiwan

    by Yi-Ju Lin, Chin-Yuan Wang, Ssu-Wei Cheng, Yu Ko

    Background: As the prevalence of diabetes mellitus (DM) continues to increase rapidly, there has been a rising need not only to assess the clinical outcomes but also the impact of DM on the health-related quality of life (HRQoL) of affected individuals. Most previous studies have found that having complications is strongly associated with decreased HRQoL in DM patients. As such, it is crucial to measure individuals’ preferences for DM-related complications in order to assess the magnitude of complications’ effect on overall HRQoL. In addition, preference scores are an essential component of cost–utility analyses (CUAs), which studies can incorporate healthcare costs, HRQoL and clinical outcomes of DM into one analysis. Objective: The aims of this study were to assess the preference scores of DM-related complications using both the standard gamble (SG), a choice-based method, and visual analogue scale (VAS), a scaling method. We also aimed to assess several possible factors that might be associated with the preference scores of the complications. Methods: This is a cross-sectional interview-administered survey, and 213 patients with type 2 DM were interviewed. The respondents’ preference scores of eleven DM-related complications were obtained using VAS and SG techniques. Demographic information, clinical characteristics and risk attitudes were also collected to explore factors that may affect patients’ preference scores. Results: Nearly one quarter of participants in Taiwan ranked at least one of the complications worse than death. The mean VAS scores ranged from 0.004 (amputation) to 0.47 (nocturnal hypoglycemia) while the mean adjusted SG scores ranged from 0.30 (blindness) to 0.66 (nocturnal hypoglycemia). There were significant differences in all of the complications’ preference scores depending on risk attitudes. Conclusion: Both the VAS and SG methods were used to elicit the preference scores of DM-related complications, and the preference scores derived could be useful for future cost utility analyses.

Patients and methods: The SOADAS was translated to Chinese and was modified based on reviews of two physicians, five diabetes educators, and two patient focus groups. A cross-sectional interviewer-administered survey was conducted in adult patients with type 2 DM who were taking OADs. The Chinese version of the SOADAS (C-SOADAS), the EuroQol 5 dimensions 3-level (EQ-5D-3L) questionnaire, and a demographic questionnaire were administered to participants. Instrument structure, internal consistency, convergent validity, and known-group validity were assessed. Results: A total of 260 DM patients were recruited. The mean score of an individual item ranged from 3.6 to 3.9, while the mean total score (out of 25 possible points) was 18.7 points. Overall, floor and ceiling effects were negligible. The Cronbachâ
