Valuating the efficiency of social security and healthcare in OECD countries from a sustainable development.

Under the goal of sustainable development, coping with the increase in social security and healthcare expenses caused by population aging is becoming increasingly important, but it is rare in the literature to evaluate the impact of social security efficiency on healthcare efficiency. This research uses the dynamic SBM two-stage model to observe the efficiencies of social security and healthcare in OECD countries. There are two findings as follows. First, the higher social security efficiency is, the better is the healthcare efficiency of countries with lower per capita GDP. Second, higher social security efficiency of National Health Service (NHS) countries denote better healthcare efficiency. When the financial source of the social security system is taxation, then it is more likely to bring higher efficiency to healthcare.

Chemoresistance in acute myeloid leukemia: An alternative single-cell RNA sequencing approach.

Our previous study demonstrated that myc, mitochondrial oxidative phosphorylation, mTOR, and stemness are independently responsible for chemoresistance in acute myeloid leukemia (AML) cells. This study aimed to identify potential mechanisms of chemoresistance of the "7 + 3" induction in AML by using a single-cell RNA sequencing (scRNA-seq) approach. In the present study, 13 untreated patients with de novo AML were enrolled and stratified into two groups: complete remission (CR; n = 8) and non-CR (n = 5). Single-cell RNA sequencing was used to analyze genetic profiles of 28,950 AML cells from these patients; results were validated using a previously published bulk RNA-seq dataset. Our study results showed chemoresistant AML cells had premature accumulation during early hematopoiesis. Hematopoietic stem cell-like cells from the non-CR group expressed more leukemic stem cell markers (CD9, CD82, IL3RA, and IL1RAP) than those from the CR group. Chemoresistant progenitor cells had impaired myeloid differentiation owing to early arrest of hematopoiesis. Notably, AML cells analyzed by scRNA-seq and bulk RNA-seq harbored a comparable myeloid lineage cell fraction, which internally validated our results. Using the TCGA database, our analysis demonstrated that patients with AML with higher expression of chemoresistant genetic markers (IL3RA and IL1RAP) had a worse overall survival (p < 0.01 for IL3RA; p < 0.05 for IL1RAP). In conclusion, AML cells responsive and resistant to the "7 + 3" induction were derived from a diverse cancerous hematopoietic stem cell population, as indicated by the specific genetic biomarkers obtained using scRNA-seq approach. Furthermore, arrest of hematopoiesis was shown to occur earlier in chemoresistant AML cells, furthering the current understanding of chemoresistance in AML.

Lipid Droplets in Lung Cancers Are Crucial for the Cell Growth and Starvation Survival.

For rapid and unlimited cell growth and proliferation, cancer cells require large quantities of nutrients. Many metabolic pathways and nutrient uptake systems are frequently reprogrammed and upregulated to meet the demand from cancer cells, including the demand for lipids. The lipids for most adult normal cells are mainly acquired from the circulatory system. Whether different cancer cells adopt identical mechanisms to ensure sufficient lipid supply, and whether the lipid demand and supply meet each other, remains unclear, and was investigated in lung cancer cells. Results showed that, despite frequent upregulation in de novo lipogenesis and the lipid transporter system, different lung cancer cells adopt different proteins to acquire sufficient lipids, and the lipid supply frequently exceeds the demand, as significant amounts of lipids stored in the lipid droplets could be found within lung cancer cells. Lipid droplet surface protein, PLIN3, was found frequently overexpressed since the early stage in lung cancer tissues. Although the expression is not significantly associated with a specific gender, age, histology type, disease stage, and smoking habit, the frequently elevated expression of PLIN3 protein indicates the importance of lipid droplets for lung cancer. These lipid droplets are not only for nutrient storage, but are also crucial for tumor growth and proliferation, as well as survival in starvation. These results suggest that manipulation of lipid droplet formation or TG storage in lung cancer cells could potentially decrease the progression of lung cancer. Further exploration of lipid biology in lung cancer could help design novel treatment strategies.

Risk factors of acute renal impairment after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

BACKGROUND: Acute renal impairment (ARI) is a major complication after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for cancer patients with peritoneal metastases. This study aimed to investigate the incidence and identify the risk factors of post-HIPEC creatinine increased. METHODS: From April 2015 to December 2019, demographic and perioperative data of 169 patients undergoing CRS/HIPEC with a preoperative creatinine level <1.5 mg/dL were retrospectively reviewed. Renal impairment was defined according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. The risk factors of creatinine increased were analyzed using univariate and multiple logistic regression analyses. RESULTS: Among the 169 enrolled patients, 21 (12.4%) had postoperative creatinine increased (ARI group) and 148 (87.6%) did not (non-ARI group). Significantly more of the ARI group received a cisplatin HIPEC regimen than the non-ARI group (71.4 vs. 37.8%, p = 0.004). Multiple logistic regression analysis revealed that the patients who received a cisplatin HIPEC regimen (adjusted odds ratio [AOR] = 11.38, p < 0.001) and peritoneal dialysis solution as HIPEC perfusate (AOR = 7.07, p = 0.002) were more likely to develop post-HIPEC creatinine increased. CONCLUSIONS: Identifying the risk factors of post-HIPEC creatinine increased can help to improve patient selection, a dose of HIPEC regimens modification and perioperative care. We also identified the detrimental renal effect of peritoneal dialysis solution as HIPEC perfusate. More prospective studies are warranted to confirm these findings.

Performance of Bioelectrical Impedance Analysis in the Estimation of Bone Mineral Content in Healthy Children Aged 6-12 Years.

BACKGROUND: Bioelectrical impedance analysis (BIA) is a widely available tool which provides mineral estimate. However, BIA is not currently recognized as a bone mineral measuring method. This study aimed to explore the ability of BIA to predict bone mineral content (BMC) in children, using dual-energy X-ray absorptiometry as a gold standard. METHODS: Healthy children aged 6-12 years (n = 176) were recruited for BIA and dual-energy X-ray absorptiometry measurements. Predictive models were generated using basic indices (age, height, weight, waist circumference, hip circumference, etc.) and BIA parameters (minerals, fat mass, and fat free mass). RESULTS: The root-mean-square deviation and R2 for the total BMC predictive model were 0.089 kg and 0.926, respectively using height and weight as predictors whereas 0.113 kg and 0.886, respectively using minerals by BIA. The root-mean-square deviation and R2 for the subtotal BMC predictive model were 0.080 kg and 0.935, respectively using height and weight as predictors whereas 0.098 kg and 0.906, respectively using minerals by BIA. The best predictive models included basic indices and BIA parameters as predictors, but they had only slightly better performance over simple models. CONCLUSIONS: Mineral content by BIA was good predictor of total and subtotal BMC in healthy children but with similar overall model performance compared to basic indices. More complex models combined all the predictive variables gave better prediction power, but of little improvement to these simple models. The BIA instrument does not appear to be useful in estimating BMC in healthy children as basic indices are more widely available measures but provide comparable performance. Future studies are needed to determine the clinical usefulness of the more complex prediction model in children with disease or children in other subgroups.

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy for peritoneal malignancy: preliminary results of a multi-disciplinary teamwork model in Asia.

BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is an emerging surgical procedure for peritoneal carcinomatosis (PC). CRS/HIPEC is a complicated treatment that requires multi-disciplinary teamwork (MDT), which may be lacking when establishing a CRS/HIPEC programme. Herein, we report our preliminary treatment outcomes with the early implementation of an MDT model for CRS/HIPEC. METHODS: From April 2015 to December 2016, 45 patients with a diagnosis of PC who received CRS/HIPEC were reviewed retrospectively in a single institution in Taiwan. RESULTS: Among the 45 patients, CRS was mainly performed by laparotomy (n = 42), and only three patients with limited PC underwent laparoscopic CRS. The first 13 patients received treatment before the MDT had been established (group 1), and the other 32 patients were treated after the MDT had been established (group 2). The highest peri-HIPEC body temperature in group 2 was significantly lower than that in group 1 (36.8 °C vs. 37.5 °C, p < 0.001). Overall, eight patients experienced major complications. The trend of a lower major complication rate was observed after the MDT model had been implemented (30.7% in group 1 vs. 12.4% in group 2, p = 0.202). Pre-CRS/HIPEC abdominal pain significantly increased the risk of post-operative major complications (p = 0.017). CONCLUSIONS: Our experience suggests that the early implementation of an MDT model when establishing a CRS/HIPEC programme at a single institution may result in a higher complete cytoreduction rate and lower major complication rate, and also shorten the learning curve of this complicated procedure.

Epidermal growth factor activates telomerase activity by direct binding of Ets-2 to hTERT promoter in lung cancer cells.

Growth signals are directly or indirectly involved in telomerase regulation. In this study, we investigated molecular mechanisms of the effect of EGF (epidermal growth factor) on regulating hTERT (human telomerase reverse transcriptase) expression. To elucidate specific transcription factors involved in EGF-stimulated hTERT transcription in A549 and H1299 lung cancer cells, transcription factors drives hTERT promoter activity, such as Myc, Mad, and Ets-2, was evaluated on luciferase reporter assay. The upregulation of hTERT promoter by Ets-2 and Myc were abolished by Mad. Using DAPA (DNA affinity precipitation assay), Ets-2 binding to SNP (T) was stronger than Ets-2 binding to SNP (C) at -245 bp upstream of the transcription start site within the core promoter of hTERT. Ets-2 silence by siRNA decreased hTERT expression at mRNA and protein levels. The regulation of hTERT promoter by EGF/Ets-2 was diminished via the EGFR kinase signal pathway-specific inhibitors AG1478 and Iressa. Inhibitors of Erk and Akt inhibited Ets-2-activated hTERT promoter activity. These data suggested that Ets-2, a genuine cancer-specific transcription factor, is actively involved in EGFR kinase-induced hTERT overexpression pathway in lung cancer cells. Blockage of this pathway may contribute to targeted gene therapy in lung cancer.

Abdominal obesity validates the association between elevated alanine aminotransferase and newly diagnosed diabetes mellitus.

To examine how elevated alanine aminotransferase (ALT) could be associated with newly diagnosed diabetes mellitus. We conducted a cross-sectional analysis on a mass health examination. The odds ratios (ORs) for diabetes mellitus and newly diagnosed diabetes mellitus were compared between people with and without abdominal obesity, together with and without elevated ALT levels. 5499 people were included in this study. Two hundred fifty two (4.6%) fulfilled the diagnosis of diabetes mellitus with 178 (3.2%) undiagnosed before. Metabolic syndrome was vigorously associated with diabetes mellitus and newly diagnosed diabetes mellitus (12.4% vs. 1.4% and 9.0% vs. 0.9%), but elevated ALT alone was not. However, coexisting with obesity, elevated ALTs were robustly associated with diabetes mellitus and newly diagnosed diabetes mellitus. For the incidence of newly diagnosed diabetes mellitus, in comparison to non-obese people with normal ALT (1.7%, OR = 1), obese people especially with elevated ALT levels had significantly higher ORs (obese with ALT ≤ 40 U/L: 4.7%, OR 1.73, 95% CI 1.08-2.77, P 0.023; ALT 41-80 U/L: 6.8%, OR 2.06, 95% CI 1.20-3.55, P 0.009; ALT 81-120 U/L: 8.8%, OR 3.07, 95% CI 1.38-6.84, P 0.006; ALT > 120 U/L: 18.2%, OR 7.44, 95% CI 3.04-18.18, P < 0.001). Abdominal obesity validates the association between elevated alanine aminotransferase and diabetes mellitus and newly diagnosed diabetes mellitus. People with abdominal obesity, especially with coexisting elevated ALT levels should be screened for undiagnosed diabetes mellitus.

Performance of Microsoft Azure Kinect DK as a tool for estimating human body segment lengths.

The Microsoft Kinect depth sensor, with its built-in software that automatically captures joint coordinates without markers, could be a potential tool for ergonomic studies. This study investigates the performance of Kinect in limb segment lengths using dual-energy X-ray absorptiometry (DXA) as a reference. Healthy children and adults (n = 76) were recruited for limb length measurements by Kinect and DXA. The results showed consistent ratios of arm, forearm, thigh, and leg lengths to height, which were 0.16, 0.14, 0.23, and 0.22 respectively, for both age groups and methods. Kinect exhibited perfect correlation among all limb lengths, indicating fixed proportions assumed by its algorithm. Comparing the two methods, there was a strong correlation (R = 0.850-0.985) and good to excellent agreement (ICC = 0.829-0.977), except for the right leg in adults, where agreement was slightly lower but still moderate (ICC = 0.712). The measurement bias between the methods ranged from - 1.455 to 0.536 cm. In conclusion, Kinect yields outcomes similar to DXA, indicating its potential utility as a tool for ergonomic studies. However, the built-in algorithm of Kinect assumes fixed limb proportions for individuals, which may not be ideal for studies focusing on investigating limb discrepancies or anatomical differences.

The Expression of TP63 as a Biomarker of Early Recurrence in Resected Esophageal Squamous Cell Carcinoma after Neoadjuvant Chemoradiotherapy.

Esophageal cancer ranks among the ten most common cancers worldwide. Despite the adoption of neoadjuvant concurrent chemoradiotherapy (nCCRT) followed by surgery as the standard treatment approach in recent years, the local recurrence rate remains high. In this study, we employed RNA-seq to investigate distinctive gene expression profiles in esophageal squamous cell carcinoma (ESCC) with or without recurrence following a standard treatment course. Our findings indicate that recurrent ESCC exhibits heightened keratinizing and epidermis development activity compared to non-recurrent ESCC. We identified TP63 as a potential candidate for distinguishing clinical outcomes. Furthermore, immunohistochemistry confirmed the trend of TP63 overexpression in ESCC recurrence. Patients with elevated TP63 expression had poorer overall survival and lower 3-year recurrence-free survival. This study underscores the potential of TP63 as a biomarker for detecting cancer recurrence and suggests its role in guiding future treatment options.

Identification of a novel norketamine precursor from seized powders: 2-(2-chlorophenyl)-2-nitrocyclohexanone.

The identification of new psychoactive substances (NPSs) and their precursors is crucial to understand trends in NPSs so that they can be regulated before they pose a serious threat to human health. In this case, 24 bags containing approximately 600 kg of yellow powder were seized; the smugglers had been monitored for 3 years by the officers of Taiwan's Ministry of Justice Investigation Bureau. A handheld Raman analyzer yielded a positive result for N-boc norketamine; thus, the seized powder was sent to this laboratory for confirmation through gas chromatography-mass spectrometry, liquid chromatographyhigh-resolution mass spectrometry, proton nuclear magnetic resonance (1H NMR), carbon-13 nuclear magnetic resonance (13C NMR), two-dimensional correlation NMR measurements (2D_COSY), heteronuclear single-quantum correlation NMR measurements (2D_HSQC), and single-crystal X-ray diffraction. This thermolabile powder was subsequently identified as 2-(2-chlorophenyl)- 2-nitrocyclohexanone (2-CPNCH), which can be employed as a precursor for the synthesis of norketamine and is available commercially. Norketamine has similar pharmacological effects to ketamine and phencyclidine but is not regulated in many countries. In this case report, mass fragments, 1H NMR, 13C NMR, 2D_COSY, and 2D_HSQC data of 2-CPNCH are presented; moreover, how criminals exploit the loopholes in the law for conducting unauthorized drug manufacturing is discussed.

AGR2 expression as a predictive biomarker for therapy response in esophageal squamous cell carcinoma.

Despite multidisciplinary therapy, the prognosis is poor for esophageal squamous cell carcinoma (ESCC). In the locally advanced stage, neoadjuvant chemoradiotherapy (nCRT) followed by surgery could provide survival benefits to some patients. Here, we aimed to identify for tumor therapy response a biomarker based on RNA sequencing. We collected endoscopic biopsies of 32 ESCC patients, who were divided according to nCRT response, into two groups: the complete response group (n = 13) and the non-complete response group (n = 19). RNA-sequencing data showed that 464 genes were differentially expressed. Increased in non-complete response group, 4 genes increased expressions were AGR2 (anterior gradient 2), GADD45B (growth arrest and DNA damage inducible beta), PPP1R15A (protein phosphatase 1 regulatory subunit 15A) and LRG1 (leucine rich alpha-2-glycoprotein 1). The areas under the curve (AUC) of the AGR2 gene was 0.671 according to read counts of RNA-seq and therapy response of nCRT. In vitro study showed that apoptosis cell was significantly increased in the AGR2-knockdown TE-2 cell line treated with cisplatin and 5-Fluorouracil (5-FU), when compared with si-control. Results suggest that in ESCC, the AGR2 gene is a promising and predictive gene marker for the response to anti-tumor therapy.

Quality of life and symptom distress after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/ HIPEC) for peritoneal surface malignancy can effectively control the disease, however it is also associated with adverse effects which may affect quality of life (QoL). AIM: To investigate early perioperative QoL after CRS/HIPEC, which has not been discussed in Taiwan. METHODS: This single institution, observational cohort study enrolled patients who received CRS/HIPEC. We assessed QoL using the Taiwanese version of the MD Anderson Symptom Inventory (MDASI-T) and European Organization Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30). Participants completed the questionnaires before CRS/HIPEC (S1), at the first outpatient follow-up (S2), and 3 mo after CRS/HIPEC (S3). RESULTS: Fifty-eight patients were analyzed. There was no significant perioperative difference in global health status. Significant changes in physical and role functioning scores decreased at S2, and fatigue and pain scores increased at S2 but returned to baseline at S3. Multiple regression analysis showed that age and performance status were significantly correlated with QoL. In the MDASI-T questionnaire, distress/feeling upset and lack of appetite had the highest scores at S1, compared to fatigue and distress/feeling upset at S2, and fatigue and lack of appetite at S3. The leading interference items were working at S1 and S2 and activity at S3. MDASI-T scores were significantly negatively correlated with the EORTC QLQ-C30 results. CONCLUSION: QoL and symptom severity improved or returned to baseline in most categories within 3 mo after CRS/HIPEC. Our findings can help with preoperative consultation and perioperative care.

Electrical characterization of single cells using polysilicon wire ion sensor in an isolation window.

A polysilicon wire (PSW) sensor can detect the H(+) ion density (pH value) of the medium coated on its surface, and different cells produce different extracellular acidification and hence different H(+) ion densities. Based on this, we used a PSW sensor in combination with a mold-cast polydimethylsiloxane (PDMS) isolation window to detect the adhesion, apoptosis and extracellular acidification of single normal cells and single cancer cells. Single living human normal cells WI38, MRC5, and BEAS-2B as well as non-small-cell lung cancer (NSCLC) cells A549, H1299, and CH27 were cultivated separately inside the isolation window. The current flowing through the PSW channel was measured. From the PSW channel current change as a function of time, we determined the cell adhesion time by observing the time required for the current change to saturate, since a stable extracellular ion density was established after the cells were completely adhered to the PSW surface. The apoptosis of cells can also be determined when the channel current change drops to zero. We found that all the NSCLC cells had a higher channel current change and hence a lower pH value than the normal cells anytime after they were seeded. The corresponding average pH values were 5.86 for A549, 6.00 for H1299, 6.20 for CH27, 6.90 for BEAS-2B, 6.96for MRC5, and 7.02 for WI38, respectively, after the cells were completely adhered to the PSW surface. Our results show that NSCLC cells have a stronger cell-substrate adhesion and a higher extracellular acidification rate than normal cells.

Assessment of total and regional bone mineral density using bioelectrical impedance vector analysis in elderly population.

This study aimed to investigate the relationship between bone mineral density (BMD) and height-adjusted resistance (R/H), reactance (Xc/H) and phase angle (PhA). A total of 61 male and 64 female subjects aged over 60 years were recruited from middle Taiwan. The R and Xc were measured using Bodystat Quadscan 4000 at a frequency of 50 kHz. BMD at the whole body, L2-L4 spine, and dual femur neck (DFN), denoted as BMDTotal, BMDL2-L4, and BMDDFN, were calculated using a Hologic DXA scanner. The R-Xc graph was used to assess vector shift among different levels of BMD. BMD was positively correlated with Xc/H and negatively correlated with R/H (p < 0.001). The General Linear Model (GLM) regression results were as follows: BMDTotal = 1.473-0.002 R/H + 0.007 Xc/H, r = 0.684; BMDL2-L4 = 1.526-0.002 R/H + 0.012 Xc/H, r = 0.655; BMDDFN = 1.304-0.002 R/H + Xc/H, r = 0.680; p < 0.0001. Distribution of vector in the R-Xc graph was significantly different for different levels of BMDTotal, BMDL2-L4 and BMDDFN. R/H and Xc/H were correlated with BMD in the elderly. The linear combination of R/H and Xc/H can effectively predict the BMD of the whole body, spine and proximal femur, indicating that BIVA may be used in clinical and home-use monitoring tool for screening BMD in the elderly in the future.

Prediction of Nonalcoholic Fatty Liver Disease by Anthropometric Indices and Bioelectrical Impedance Analysis in Children.

Background: Nonalcoholic fatty liver disease (NAFLD) is highly prevalent in children and is associated with obesity. Objectives: To test whether addition of bioelectrical impedance analysis (BIA) parameters to BMI and anthropometric indices improves the prediction performance of NAFLD than BMI z score (BAZ) alone. Methods: This cross-sectional study recruited 933 children 6-12 years of age for anthropometric measure, BIA, and liver ultrasound. Prediction models of the BAZ, anthropometric, and BIA sets were built in children with obesity using machine learning algorithms. Results: Prevalences of NAFLD were 44.4% (59/133) and 20% (12/60) in boys and girls with obesity, respectively. In both sexes, BAZ set performed worst; adding anthropometric indices into the model improved the model performance, whereas BIA parameters were the best approach for predicting NAFLD. The best result in boys achieved had an accuracy of 75.9% and area under receiver operating characteristic curve of 0.854. In girls, the best result achieved had an F-measure score of 0.615, Matthews correlation coefficient of 0.512, and area under precision-recalled curve of 0.697. Conclusion: BIA is a simple and highly precise tool that yields better NAFLD prediction model than anthropometric indices, and much better performance than BAZ. This study suggests BIA as a potential predictor for pediatric NAFLD.

Effects of Laser Acupuncture Therapy for Patients With Inadequate Recovery From Bell's Palsy: Preliminary Results From Randomized, Double-Blind, Sham-Controlled Study.

Introduction: Inadequate recovery from Bell's palsy exists in a third of patients and results in physical and social impairments. The controversial nature of existing medical treatment options means that novel, alternative approaches are needed. In basic and clinical studies, low-level laser therapy (LLLT) has proven successful in regenerating peripheral nerves. Laser acupuncture therapy (LAT) is a rapidly growing treatment modality; however, its effectiveness for treating chronic Bell's palsy is unknown. The feasibility of this innovative approach is the focus of this pilot study. Methods: A two-armed, parallel, randomized, investigator-subject-assessor-blinded, sham-controlled pilot study was conducted, and 17 eligible subjects were randomly allocated to either LAT (n=8) or sham LAT (n=9). The LAT group received three treatments each week for six weeks (18 sessions), while the sham LAT group received the same procedure but with a sham laser device. The change from baseline to week 6 in the social subscale of the Facial Disability Index (FDI) was the primary outcome. Secondary outcomes were changes in the House-Brackmann facial paralysis scale (HB), the Sunnybrook facial grading system (SB) and a stiffness scale at weeks 3 and 6. Results: A significant difference was shown in the HB score (P=0.0438) between baseline and week 3 and borderline significance was observed in both SB and stiffness scores from baseline to week 6 (P=0.0598 and P=0.0980 respectively). There was no significant difference in the FDI score between baseline and week 6. Conclusion: To the best of our knowledge, this clinical trial is the first such investigation on this topic. Our findings suggest that using LAT may have clinical effects on long-term complications of Bell's palsy and justify further large-scale studies.

Acupuncture Decreased the Risk of Coronary Heart Disease in Patients with Osteoarthritis in Taiwan: A Nationwide Matched Cohort Study.

Objectives: Patients with osteoarthritis (OA) are more likely to develop coronary heart disease (CHD) than the general population. Acupuncture is commonly used in OA patients; however, the therapeutic effect of acupuncture on the risk of CHD in patients with OA and the association between OA patients and their risk to develop CHD in Taiwan are unknown. We investigated the risk of CHD according to acupuncture use in OA patients and compared it with the general population. Design: Records obtained from Taiwan's National Health Insurance Research Database identified 84,773 patients with OA, which were compared with 727,359 patients without OA diagnosis. Five thousand forty-six of those who met study inclusion criteria had 1:1 frequency matching and were categorized as OA-acupuncture cohort (n = 1682), OA nonacupuncture cohort (n = 1682), and non-OA cohort (n = 1682). Cox proportional hazards regression analysis determined the risk of CHD, which was defined as the study main outcome. Therapeutic effects of acupuncture and medical expenditure were also analyzed. Results: OA nonacupuncture cohort had 3.04 higher risk to develop CHD compared with OA-acupuncture cohort (95% confidence interval [CI], 2.54-3.63, p < 0.001) and non-OA cohort had 1.88 higher risk to develop CHD compared with OA-acupuncture cohort (95% CI, 1.52-2.32, p < 0.001). In subgroup analyses, OA patients treated with both acupuncture and oral steroids were at significantly lower risk of CHD compared with those who used neither (adjusted hazard ratio 0.34; 95% CI, 0.22-0.53), and OA patients treated with acupuncture had the lowest medical expenditure in a follow-up time of 6 months, and 3 and 5 years. Conclusion: This is the first large-scale investigation in Taiwan that shows the association between OA and CHD and the beneficial effects of acupuncture in OA patients, and their associated risk to develop CHD. Our results may provide valuable information for health policy decision making. Further randomized controlled trials are needed to confirm these observational findings.
