The Association between Diabetic Retinopathy and Macular Degeneration: A Nationwide Population-Based Study.

OBJECTIVE: Age-related macular degeneration (AMD), particularly its exudative form, is a primary cause of vision impairment in older adults. As diabetes becomes increasingly prevalent in aging, it is crucial to explore the potential relationship between diabetic retinopathy (DR) and AMD. This study aimed to assess the risk of developing overall, non-exudative, and exudative AMD in individuals with DR compared to those without retinopathy (non-DR) based on a nationwide population study in Taiwan. METHODS: A retrospective cohort study was conducted using the Taiwan National Health Insurance Database (NHIRD) (2000-2013). A total of 3413 patients were placed in the study group (DR) and 13,652 in the control group (non-DR) for analysis. Kaplan-Meier analysis and the Cox proportional hazards model were used to calculate the hazard ratios (HRs) and adjusted hazard ratios (aHRs) for the development of AMD, adjusting for confounding factors, such as age, sex, and comorbid conditions. RESULTS: Kaplan-Meier survival analysis indicated a significantly higher cumulative incidence of AMD in the DR group compared to the non-DR group (log-rank test, p < 0.001). Adjusted analyses revealed that individuals with DR faced a greater risk of overall AMD, with an aHR of 3.50 (95% CI = 3.10-3.95). For senile (unspecified) AMD, the aHR was 3.45 (95% CI = 3.04-3.92); for non-exudative senile AMD, it was 2.92 (95% CI = 2.08-4.09); and for exudative AMD, the aHR was 3.92 (95% CI = 2.51-6.14). CONCLUSION: DR is a significant risk factor for both overall, senile, exudative, and non-exudative AMD, even after adjusting for demographic and comorbid conditions. DR patients tend to have a higher prevalence of vascular comorbidities; however, our findings indicate that the ocular pathologies inherent to DR might have a more significant impact on the progression to AMD. Early detection and appropriate treatment of AMD is critically important among DR patients.

Long-term safety of total knee arthroplasty in patients with chronic kidney disease in Taiwan: a retrospective cohort study.

BACKGROUND: Chronic kidney disease (CKD) is a prevalent condition in Taiwan, and the incidence of total knee arthroplasty (TKA) is on the rise. This study aimed to evaluate the postoperative results of patients with different degrees of CKD after TKA, using data from the Taiwan National Health Insurance Research Database. METHODS: The study analyzed 3,078 patients who received TKA from 2012 to 2017, equally divided into three groups: none-CKD, mild CKD (without dialysis), and severe CKD (with dialysis). Propensity score matching was used to minimize selection bias. RESULTS: After TKA, there was no significant difference in the risk of debridement surgery for infection between the three groups (adjusted HR of mild CKD 0.71 95% CI = 0.36 - 1.38, P = 0.3073; adjusted HR of severe CKD: 1.14, 95% CI = 0.63 - 2.06, P = 0.6616). However, CKD patients requiring dialysis had a significantly higher risk of mortality (adjusted HR 1.98, 95% CI = 1.57 - 2.50, P < 0.001) and readmission within 90 days of any causes (adjusted HR 1.83, 95% CI = 1.48 - 2.26, P < 0.001) than non-CKD and mild CKD patients. CONCLUSION: Severe CKD patients needing dialysis after TKA have a higher risk of mortality and readmission rates than that of the non-CKD or mild CKD patients. If the patient is in the early stage of CKD, their prognosis after receiving TKA is expected to be as good as non-CKD patients. LEVEL OF EVIDENCE: IV; well-designed cohort study.

Examining the Impact of the Current Reimbursement Regulation on Patient Access to Innovative Medical Devices in Taiwan: Insights From 8 Years' Reimbursement Data.

OBJECTIVES: This study aimed to assess the impact of the reimbursement regulation of medical devices (Regulation), introduced by the National Health Insurance Administration (NHIA) in 2013, on patients' access to innovative medical devices in Taiwan. METHODS: Analysis of the amount of time needed from application for NHIA reimbursement for new medical devices to receiving the decision from NHIA was done using the nonreimbursement product list featured on the NHIA website. Additionally, Welch analysis of variance was used to compare the amount of time it took from application to NHIA with reimbursement decisions made by the NHIA for different nonreimbursement code categories. Further, related Pharmaceutical Benefit Reimbursement Scheme meeting minutes were analyzed to obtain more detailed information concerning medical devices' reimbursement or not. RESULTS: From December 2012 to June 2021, the overall reimbursement percentage was 56.7%, and the average amount of time between application and reimbursement was 856.7 ± 474.7 days. The mandatory reimbursement rate was about 45%. NHIA reimbursement decisions as special medical devices also take a longer amount of time, because the applicants need to agree to the decision (P < .05). The NHIA decision-making process for nonreimbursement medical devices requires a significantly longer amount of time than for general materials (eg, suture, etc) decisions. CONCLUSIONS: Although the Regulation resolves payment issues, it also increases the amount of time to reach reimbursement decisions, thus hindering patient access to innovative medical devices. The study suggests that the review process needs to be simplified concerning reimbursement notification, using local real-world data to support reimbursement decisions.

Trends and Age-Period-Cohort Effect on Incidence of Male Breast Cancer from 1980 to 2019 in Taiwan and the USA.

Although male breast cancer (MBC) is globally rare, its incidence significantly increased from 1990 to 2017. The aim of this study was to examine variations in the trends of MBC incidence between populations in Taiwan and the USA from 1980 to 2019. The Taiwan Cancer Registry database and the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute of the USA were used. The age-standardized incidence rate was calculated using the world standard population in 2000. The long-term trends of the age, time period, and birth cohort effect on MBC incidence rates were estimated using the SEER Age-Period-Cohort Web Tool. The results revealed that the incidence of MBC in both countries increased from 2010 to 2019 (Taiwan: average annual percentage change (AAPC) = 2.59%; USA: AAPC = 0.64%). The age and period effects on the incidence rates in both countries strengthened, but the cohort effect was only identified in Taiwan (Rate ratio: 4.03). The identified cohort effect in this study bears resemblance to that noted in a previous investigation on female breast cancer in Taiwan. This suggests the possible presence of common environmental factors influencing breast cancer incidence in both genders, such as a high fat diet and xenoestrogen.

Adverse events from HPV vaccination in Taiwan.

The safety of human papillomavirus (HPV) vaccines has been evaluated continuously in pre-licensure clinical trials, post-marketing surveillance systems, and observational studies. Most studies have found no significant association between serious adverse events and HPV vaccination. However, these studies have focused on Western populations; similar studies focusing on Asian populations are insufficient. Our retrospective cohort study used the HPV-vaccination records of junior high-school adolescent girls aged 12-15 years between 2013 and 2018 in Taiwan's National Immunization Information System and linked them to a registry for beneficiaries in Taiwan's National Health Insurance Database (NHID) to establish the vaccinated group. We selected 19 serious diseases as serious adverse events. We compared the incidence rates of these serious adverse events between the vaccinated group and girls in the same age group population, and we calculated the standardized incidence ratio (SIR) to evaluate the risk of serious adverse events after HPV vaccination. Because of the onset of different types of diseases, we set three periods after the subjects received HPV vaccination: within 3 months, within 1 year, and during the study period (2013-2018). The results showed the incidence rates and the SIRs of 19 selected adverse events. Among the 19 selected serious adverse events, the disease with the highest incidence rate during the study period was fibromyalgia (73.23 cases per million population), and the disease with the lowest incidence rate during the study period was Crohn's disease (0.15 cases per million population). The results showed no statistically significant increases in the risk of 19 selected serious adverse events and indicated no association between HPV vaccination and serious adverse events. Given the benefits and safety of HPV vaccination, our research can reduce concerns about vaccine side effects, inform health policies and improve public and clinician's acceptance of HPV vaccine policy.

Trends and sex-specific incidence of upper urinary tract cancer in Taiwan: A birth cohort study.

BACKGROUND: Taiwan has one of the highest incidences of upper tract urothelial cancer (UTUC) worldwide, especially in women; however, no nationwide, long-term follow-up study has evaluated this. METHODS: We investigated the incidence of UTUC in Taiwan using data from the national population-based Taiwan Cancer Registry database (1985-2019). We divided the birth cohort into nine 5-year age groups and calculated the age-specific incidence for these groups according to the corresponding birth years. RESULTS: The average annual percent change in the incidence of renal pelvis cancer from 1985 to 2019 showed sex-specific differences, with 3.5% and 5.3% increases in the incidences in men and women, respectively. The age-specific incidence rate for renal pelvis cancer among women showed a gradual increase in the group with older women as well as an increase over time in each age group. The results of a birth cohort analysis revealed that younger cohorts had higher incidence rates of renal pelvis cancer than older cohorts did. CONCLUSION: We demonstrated that the incidence of UTUC is unusually high among older Taiwanese women and that younger cohorts have a high risk of UTUC than older cohorts.

Association between clinical use of lansoprazole and the risk of type 2 diabetes mellitus: a pharmacoepidemiological cohort study.

BACKGROUND: Proton pump inhibitors (PPIs) are common and widely used for gastrointestinal-related disorders. Lansoprazole is one of PPIs with potential benefits of anti-inflammation, reduced oxidative stress, and anti-diabetes. The aims of this study are to determine whether lansoprazole imparts differential risk of type 2 diabetes as compared with other PPIs. METHODS: A population-based retrospective cohort study was conducted using the National Health Insurance Research Database in Taiwan. Patients who received lansoprazole more than 90 days and without records of use of other PPIs between January 1, 2000 and December 31, 2005 (the exposure period) were considered as the exposed cohort (n = 1668). In comparison, patients who received other PPIs more than 90 days and without use of lansoprazole in the exposure period were treated as the comparison cohort (n = 3336).The primary outcome was the new-onset of type 2 diabetes mellitus (T2DM). The association between use of lansoprazole and the risk of T2DM was determined by hazard ratios (HRs) and 95% confidence intervals (CIs) derived from multivariable Cox proportional hazards models. RESULTS: The lansoprazole cohort showed a significantly reduced risk of T2DM with an adjusted HR of 0.65 (95% CI 0.56-0.76). Interestingly, the inverse association between use of lansoprazole and risk of T2DM was observed in both genders and in various age groups. CONCLUSION: The present study findings suggest that lansoprazole was associated with a reduced risk of T2DM compared with other PPIs. Further studies are needed to determine the clinical implications of the present study.

Association between clinical use of nifedipine and the risk of osteoporosis: a nationwide retrospective cohort study.

Nifedipine is one of the common calcium channel blockers (CCBs) for hypertension that induce peroxisome-proliferator-activated receptor γ coactivator 1-α, which is envisioned as a potential therapeutic target in bone disease. The findings of this retrospective cohort study suggest that patients who receive nifedipine may have a potential protective effect on osteoporosis in comparison to other CCBs. INTRODUCTION: Nifedipine was one L-type dihydropyridine calcium channel blocker (CCB) that can improve bone loss. However, epidemiological studies on the association between the use of nifedipine and osteoporosis risk are limited. Thus, this study aimed to evaluate the association between the clinical use of nifedipine and the risk of osteoporosis. METHODS: This retrospective cohort was conducted using the National Health Insurance Research Database of Taiwan from 2000 to 2013. The study includes 1225 patients receiving nifedipine (the exposed cohort) and 4900 patients receiving other CCBs (the comparison cohort). The primary outcome was the diagnosis of osteoporosis. The hazard ratios (HRs) and 95% confidence intervals (CIs) were used to assess the association between the use of nifedipine and the risk of osteoporosis. RESULTS: Patients receiving nifedipine treatment had a reduced risk of osteoporosis as compared with those undergoing other CCB treatments (adjusted HR, 0.44; 95% CI, 0.37-0.53). Moreover, this inverse association is evident in both sexes and various age groups. CONCLUSIONS: This population-based cohort study demonstrated that nifedipine may have potential protective effect on osteoporosis compared with other CCBs. The clinical implications of the present study need further investigation.

Incidence trends of oral cavity, oropharyngeal, hypopharyngeal and laryngeal cancers among males in Taiwan, 1980-2019: a population-based cancer registry study.

In a country with a high prevalence of cigarette smoking, betel chewing, and alcohol drinking, cancers of the oral cavity, nasopharynx, and larynx were the fourth, twelfth and seventeenth leading causes of cancer death, respectively, for men in 2020. We analyzed patients with head and neck cancer from 1980 to 2019 from the Taiwan Cancer Registration Database and discussed the annual average percent change, average percent change, age period, and birth cohort. Obvious period effects and birth effects are seen in oral, oropharyngeal, and hypopharyngeal cancer; however, the most significant period effect was seen between 1990 and 2009, which mainly reflects the consumption of betel nuts per capita. In addition, the period effect lessens after 2010 in oral cancer and hypopharyngeal cancers, while oropharyngeal cancers remain an obvious period effect, which results from the rising prevalence of HPV. Due to the high prevalence rate of betel quid chewing and cigarette smoking in the 1990s, the government executed several acts. As a result, the age-adjusted incidence rates of oral, oropharyngeal, and hypopharyngeal cancers have flattened since 2010, which can be explained by the declining cigarette smoking rate. The strict policy indeed shows an obvious effect on the head and neck cancer incidence rates, and we expect to see a further decline in the future.

Association of Dipeptidyl Peptidase-4 Inhibitors Use with Reduced Risk of Hepatocellular Carcinoma in Type 2 Diabetes Patients with Chronic HBV Infection.

Previous studies have indicated that HBV infection and T2DM are the factors that increase the risk of developing HCC. The experimental evidence has shown that antiglycemic agents may reduce the risk of HCC. However, the effect of dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors) on the risk of HCC in T2DM patients with chronic HBV infection remains unclear. In this retrospective cohort study, we extracted patients with T2DM and chronic HBV infection from the National Health Insurance Research Database (NHIRD) in Taiwan. The cases were divided into DPP-4 inhibitors use and non-use groups, according to whether they received DPP-4 inhibitors treatment, and the risk of HCC was compared between the two groups. At the end of the follow-up, approximately 2.33% of DPP-4 inhibitors users had received an HCC diagnosis compared with 3.33% of non-DPP-4 inhibitors users (p < 0.0001). After multivariate adjustment, DPP-4 inhibitors users showed a significant reduction in HCC risk (adjusted hazard ratios (aHRs): 0.53; 95% confidence intervals (CIs): 0.44-0.65). In conclusion, this population-based retrospective cohort study indicated that, in T2DM patients with chronic HBV infection, the use of DPP-4 inhibitors significantly reduced the risk of developing HCC compared with non-DPP-4 inhibitors use.

Effects of Different Voice Rest on Vocal Function After Microlaryngeal Surgery: A Systematic Review and Meta-Analysis.

OBJECTIVES: To compare the results of a voice handicap index (VHI) scale and acoustic parameters in patients who underwent microlaryngeal surgery followed by either short-duration (voice rest for <7 days) or long-duration (≥7 days) voice rest. STUDY DESIGN: Systematic review and meta-analysis. METHODS: The PubMed, Embase, and Cochrane Library databases were systematically searched for articles published before March 1, 2021. Randomized controlled trials (RCTs) that measured the voice outcomes of patients after different durations and extents of postoperative voice restriction were included in the meta-analysis. RESULTS: Four RCTs comprising 112 patients were included in the quantitative meta-analysis. Compared with the long-duration voice rest group, the short-duration group exhibited comparable VHI scores (mean difference [MD], -7.01; 95% CI, -16.12 to 2.09; p = 0.13), maximum phonation time (MD, -2.58; 95% CI, -5.42 to 0.26; p = 0.07), and acoustic variables of jitter (MD, -1.25; 95% CI, -3.43 to 0.94; p = 0.26) and shimmer (MD, -0.79; 95% CI, -2.08 to 0.51; p = 0.24). Subgroup analysis for benign pathology and cold instruments studies demonstrated significantly better VHI scores (MD, -14.45; 95% CI, -26.19 to -2.72; p = 0.02 and MD, -15.98; 95% CI, -28.52 to -3.44; p = 0.01, respectively) in the short-duration group. CONCLUSIONS: The limited evidence does not demonstrate benefit in voice outcomes from long-duration voice rest and suggests potential unfavorable effects on compliance and quality of life, providing a rationale for short-duration voice rest after microlaryngeal surgery. More studies are required to determine the optimal duration and extent of postoperative voice rest. LEVEL OF EVIDENCE: 1 Laryngoscope, 133:154-161, 2023.

Secular Trends in Incidence of Esophageal Cancer in Taiwan from 1985 to 2019: An Age-Period-Cohort Analysis.

In Taiwan, the age-standardized incidence of EC, especially esophageal squamous cell carcinoma (ESCC), has increased substantially during the past thirty years. We described the incidence trends of EC from 1985−2019 by an average annual percentage change (AAPC) and age-period-cohort model by using Taiwan Cancer Registry data. Age-period-cohort modeling was used to estimate the period and cohort effects of ESCC and esophageal adenocarcinoma (EAC). The Spearman's correlation coefficient was used to analyze the correlation between age-adjusted incidence rates of EC and the prevalence of risk factors from national surveys. The results showed the incidence rate of ESCC in men (AAPC = 4.2, 95% CI = 3.1−5.4, p < 0.001) increased prominently from 1985−1989 to 2015−2019 while that of EAC in men (AAPC = 1.2, 95% CI = 0.9−1.5, p < 0.001) and ESCC in women (AAPC = 1.7, 95% CI = 1.4−2.1, p < 0.001) increased to a lesser degree. Increased period effects were observed in ESCC in men, ESCC in women, and EAC in men. High correlations were found between the risk factors and the increased birth-cohort effects of ESCC (p < 0.05). To conclude, the incidence of ESCC in both sex and EAC in men increased with statistical significance in recent decades. The increased prevalence of risk factors from approximately 1970−1995 could explain the increased cohort effects of ESCC.

Clinical Use of Lansoprazole and the Risk of Osteoporosis: A Nationwide Cohort Study.

BACKGROUND: Proton pump inhibitor (PPI) lansoprazole acts as a liver X receptor agonist, which plays a crucial role in the crosstalk of osteoblasts and osteoclasts in vitro and during bone turnover in vivo. However, epidemiological studies on the association between the use of lansoprazole and osteoporosis risk are limited. We aimed to determine the risk of developing osteoporosis in patients with lansoprazole use. METHODS: A retrospective cohort study was conducted using the National Health Insurance Research Database of Taiwan dated from 2000 to 2013. The study includes 655 patients with lansoprazole use (the exposed cohort) and 2620 patients with other PPI use (the comparison cohort). The main outcome was the primary diagnosis of osteoporosis. The hazard ratios (HRs) and 95% confidence intervals (CIs) were used to assess the association between the use of lansoprazole and risk of osteoporosis. RESULTS: Patients receiving lansoprazole treatment had a reduced risk of osteoporosis as compared with those undergoing other PPI therapy (adjusted HR, 0.56; 95% CI, 0.46-0.68). Moreover, this inverse association is evident in both sexes and in various age groups. CONCLUSIONS: This population-based cohort study demonstrated that lansoprazole use was associated with a reduced risk of osteoporosis. The clinical implications of the present study need further investigations.

Use of Hormone Replacement Therapy and Risk of Dementia: A Nationwide Cohort Study.

OBJECTIVE: Estrogen has the potential to influence brain physiology implicated in dementia pathogenesis. Hormone replacement therapy (HRT) might be expected to influence the risk of dementia. Observational data indicated that HRT was associated with reductions in dementia risk, but experimental evidence demonstrates that HRT increases the incidence of dementia. To determine the effect of HRT on risk of dementia, a retrospective cohort study was performed using a nationwide claims dataset in Taiwan. METHODS: A population-base longitudinal study was performed using data from the Longitudinal Health Insurance Database in Taiwan. A total of 35,024 women with HRT were enrolled as the exposed cohort and 70,048 women without HRT were selected on the basis of propensity matching as the comparison cohort. All of the subjects were followed up until the diagnosis of dementia, death, or at the end of December 31, 2013, whichever occurred first. Overall, the average duration of follow-up (±SD) in the HT and comparison cohort was 12.3(±2.3) and 12.2 (±2.4), respectively. The Cox proportional hazards regression models were conducted to produce hazard ratios (HRs) with 95% confidence intervals (CIs) to evaluate the association of HRT with the risk of dementia. RESULTS: In the follow-up period, the cumulative incidence of dementia for the HRT cohort (20.04 per 1,000) was significantly higher than the corresponding cumulative incidence for the comparison cohort (15.79 per 1,000), resulting in an adjusted hazard ratio of 1.35 (95% CI, 1.13-2.62). There was an increased risk of dementia with a higher cumulative dose of HRT prescription (p for trend <0.0001). CONCLUSION: This cohort study documented that HRT was associated with an increased risk of dementia. The clinical implications of this study merit further investigations.

Human Papillomavirus and Risk of Colorectal Cancer: An Analysis of Nationwide Claims Data.

Background and Objectives: Although human papillomavirus (HPV) is a major etiology of cervical and anogenital cancers, whether it is associated with colorectal carcinogenesis is yet undetermined. Materials and Methods: The longitudinal association of HPV infection with colorectal cancer (CRC) was evaluated using 2000-2013 data from a nationwide Taiwanese claims database. In this retrospective cohort study, 358 patients with primary HPV diagnoses (HPV-infected cohort) and 1432 patients without such a diagnosis (HPV-uninfected cohort) were recruited between 2000 and 2006. Both cohorts were followed up to identify CRC incidences from 2006 to 2013. Hazard ratios (HRs) and their 95% confidence intervals (CIs) derived from Cox proportional hazards models were used to estimate the association between HPV and CRC risk. Results: The HPV-infected cohort had a significantly higher cumulative incidence of CRC than the HPV-uninfected cohort. The presence of HPV was associated with an increased risk of CRC (adjusted HR, 1.63; 95% CI, 1.02-3.62). Furthermore, the significant HPV-CRC risk association was evident in both sexes. Conclusions: This population-based cohort study reveals longitudinal evidence that HPV is associated with an increased risk of CRC. Further studies are required to verify the role of HPV in colorectal carcinogenesis.

Age Specific Risks of Uterine Cancer in Type 2 Diabetes and Associated Comorbidities in Taiwan.

Introduction: The global incidence of uterine cancer has increased substantially in recent decades. We evaluated if the trend of increasing prevalence of diabetes mellitus (DM) and obesity are attributed to the development of uterine cancer. Methods: Using data derived from the National Health Insurance database and Taiwan Cancer Registry, multivariate Cox proportional hazards regression models were adapted to analyze the risk factors of uterine cancer with potential confounding variables. Results: There were a total of 5,104,242 women aged 30−70 years enrolled in the study and 147,772 of them were diagnosed with DM during 2005−2007. In a total of 11 years of follow-up, 14,398 subjects were diagnosed with uterine cancer. An elevated risk of uterine cancer was observed in women with DM of all ages (HR 1.66, 95% CI 1.53−1.81, p < 0.0001). The effect of DM was highest at age 30−39 years (RR 3.05, 95% CI 2.35−3.96, p < 0.0001). In the group of <50 years old, DM patients had at least a twofold higher risk of developing uterine cancer (HR 2.39, 95% CI 2.09−2.74, p < 0.0001). Subjects among all ages diagnosed with polycystic ovary syndrome (PCOS) (HR 2.91, 95% CI 2.47−3.42, p < 0.0001), obesity (HR 2.13, 95% CI 1.88−2.41, p < 0.0001), and those undergoing hormone replacement therapy (HRT) (HR 1.60, 95% CI 1.33−1.93, p < 0.0001) were also positively associated with uterine cancer. Positive associations of hyperlipidemia (HR 1.33, 95% CI 1.22−1.46, p < 0.0001) and statin use (HR 1.27, 95% CI 1.12−1.44, p = 0.0002) on uterine cancer were only observed in subjects <50 years. On the contrary, hyperlipidemia was negatively associated with uterine cancer in subjects ≥50 years (HR 0.91, 95% CI: 0.84−0.98, p = 0.0122). Conclusions: DM is in general the most important risk factor for uterine cancer, especially in premenopausal women. Obesity, PCOS, HPL, statin use, and HRT were also associated with uterine cancer in subjects younger than 50 years. Premenopausal women with DM and respective comorbidities should be aware of the development of uterine cancer.

Developing a New Region-Specific Preference-Based Measure in East and Southeast Asia.

OBJECTIVES: Almost all preference-based measures (PBMs) have been developed in Western countries, with none having been formulated in Asian countries. In this study, we construct a new generic PBM based on concept elicitation using interview surveys in East and Southeast Asian countries and qualitative analysis. METHODS: This cross-sectional study included 225 adults recruited from 9 East and Southeast Asian countries or regions (Indonesia, Japan, Korea, mainland China, Malaysia, the Philippines, Singapore, Taiwan, and Thailand). Trained interviewers conducted semistructured interviews with 25 participants from the general population of each country/region. Qualitative data were analyzed using a content analysis approach. The selection of items was determined based on interview surveys and team member discussions. The description of items was considered based on a detailed qualitative analysis of the interview survey. RESULTS: A new region-specific PBM-the Asia PBM 7 dimensions instrument-was designed. It reflects East and Southeast Asian values and comprises 7 items: pain, mental health, energy, mobility, work/school, interpersonal interactions, and burden to others. CONCLUSIONS: The new region-specific instrument is one of the first PBMs developed in the context of non-Western countries. The Asia PBM 7 dimensions contains 7 items that address the core concepts of health-related quality of life that are deemed important based on East and Southeast Asian health concepts.

The Association between Hypertriglyceridemia and Colorectal Cancer: A Long-Term Community Cohort Study in Taiwan.

(1) Background: Colorectal cancer (CRC) is the third most common malignancy and the second leading cause of cancer deaths worldwide. It often diagnosed at advanced stages, and with increasing incidence at younger generation. CRC poses a heavy financial burden and a huge public health challenge nowadays. Lipoproteins and serum lipids may have an influence on carcinogenesis by making oxidative stress, inflammation, and insulin resistance. Dyslipidemia plays a potential role in the risk of CRC. The purpose of this study is to use nationally representative samples to determine epidemiologic characteristics of CRC in the Taiwanese population, and to evaluate the associations between baseline levels of lipid profile and their effect on risk of colorectal cancer (CRC) comprehensively and quantitatively. The control of dyslipidemia in primary and secondary prevention may reduce the disease burden of CRC. (2) Methods: This is a nationwide long-term community-based prospective cohort study. Data were retrieved from the nationwide population-based Taiwanese Survey on Hypertension, Hyperglycemia and Hyperlipidemia (TwSHHH). Variables were estimated by the Cox proportional hazards model which was then further adjusted for age. We also calculated the relative ratios (RRs) of CRC for joint categories of serum cholesterol, triglyceride (TG), low-density lipoproteins cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) level, and to examine their combined effect and statistical interactions. (3) Results: Male, age, waist circumference, diabetes mellitus (DM), high TG, high cholesterol level, smoking history, and metabolic syndrome were proved to increase the risk of CRC. In addition, DM patients with a TG level ≥150 mg/dL and cholesterol ≥180 mg/dL had a 4.118-fold higher risk of CRC as compared with a TG level <150 mg/dL and cholesterol level <180 mg/dL, which was a significant difference (95% CI, 1.061−15.975; p = 0.0407). (4) Conclusions: Patients with DM should control TG and cholesterol level through diet, exercise, or taking medications more aggressively, not only for preventing cardiovascular disease, but also for first prevention of CRC. The study can be valuable for the clinicians and policy makers to implement more precisely goals about dyslipidemia management.

Association between Non-Steroidal Anti-Inflammatory Drugs Use and the Risk of Type 2 Diabetes Mellitus: A Nationwide Retrospective Cohort Study.

BACKGROUND: Although the link between non-steroidal anti-inflammatory drugs (NSAIDs) and tramadol and symptomatic hypoglycemia has been documented, there is a limited understanding of the associations of NSAIDs and tramadol with the risk of type 2 diabetes mellitus (T2DM). This study was established to evaluate the association between the clinical use of NSAIDs and the risk of T2DM. PATIENTS AND METHODS: A historical cohort study was conducted using the National Health Insurance Research Database in Taiwan dated from 2000 to 2013. Patients who received NSAIDs for at least 3 prescription orders and without co-treatment of tramadol in the exposure period (from 2000 to 2005) were considered as the exposed cohort (n = 3047). In comparison, patients who received tramadol for at least 3 prescription orders and without concomitant use of NSAIDs in the exposure period were considered as the comparison cohort (n = 9141). The primary outcome was the occurrence of T2DM. Multivariable hazard ratios (HRs) with 95% confidence intervals (CIs) derived from the Cox proportional hazard models were applied to determine the association between NSAIDs use and the risk of T2DM. RESULTS: In the average follow-up period of 9.56 years, there were 159 newly diagnosed T2DM, with an incidence rate of 56.96 per 10,000 person years in the exposed cohort. Comparatively, there were 1737 incident T2DM cases, with an incidence rate of 161.23 per 10,000 person years in the comparison cohort. Compared to the comparison cohort, the NSAIDs cohort showed a significantly reduced risk of T2DM with an adjusted HR of 0.31 (95% CI, 0.26-0.36). CONCLUSIONS: Our cohort study provides longitudinal evidence that the use of NSAIDs was associated with a reduced risk of T2DM.

Association between Dysphagia and Frailty in Older Adults: A Systematic Review and Meta-Analysis.

BACKGROUND: Increasing bodies of epidemiological evidence indicate potential associations between dysphagia and the risk of frailty in older adults. We hypothesized that older adults with symptoms of dysphagia might have a higher prevalence of frailty or prefrailty than those without dysphagia. METHODS: We systematically searched the PubMed, Embase, and Cochrane Library databases for relevant studies published through 20 April 2022. Cross-sectional and longitudinal studies that examined the associations between dysphagia and the existence of frailty or prefrailty in community-dwelling, facility-dwelling, or hospitalized adults aged 50 years or older were synthesized. The Newcastle-Ottawa Scale was used to evaluate study quality. RESULTS: The meta-analysis comprised 12 cohorts, including 5,503,543 non-frailty participants and 735,303 cases of frailty or prefrailty. Random-effect meta-analysis demonstrated a significant association between dysphagia and the risk of frailty and prefrailty (OR, 3.24; 95% CI, 2.51-4.20). In addition, we observed consistent results across the subgroups and heterogeneity assessments. CONCLUSIONS: We propose including dysphagia assessment as a critical factor in the cumulative deficit model for identifying frailty in older adults. Understanding dysphagia and the potential role of nutritional supplements in older adults may lead to improved strategies for preventing, delaying, or mitigating frailty.
