RESUMEN
BACKGROUND: The second-most common cause of cancer-related death for women worldwide is breast cancer. However, there is little information about breast cancer among women with disabilities in Taiwan. OBJECTIVES: This study investigated differences between women with and without disabilities regarding breast cancer stages and evaluated the probability of developing an advanced stage and the mortality risk of breast cancer. METHODS: This study conducted a nationwide retrospective cohort study using the National Health Insurance Research Database and other nationwide databases. Our participants were newly diagnosed breast cancer patients, including women with and without disabilities, between 2004 and 2010. We matched both of them with propensity score matching methods (1:5), and all were followed up until the end of 2016. RESULTS: This study included 50,683 participants with breast cancer. After matching, women with disabilities who did not receive breast cancer screening had a more significant proportion of advanced-stage breast cancer (19.95 %) than those without disabilities who did not receive breast cancer screening (16.87 %). After adjusting for related variables, women with disabilities were 1.27 times more likely to have advanced-stage breast cancer than those without disabilities. Additionally, after suffering from breast cancer, individuals with disabilities had a 1.23 times greater mortality risk compared to those without disabilities. CONCLUSIONS: Although cancer stages were controlled, women with disabilities still had a higher mortality risk of breast cancer. Hence, policymakers should pay more attention to women with disabilities to treat them at an early stage, which can reduce the mortality risk attributable to advanced stages.

We aimed to investigate the effects of the time from hospice and palliative care enrollment to death on the quality of care and the effectiveness and trend of healthcare utilization in patients with terminal cancer. Data on the cancer-related mortality rates between 2005 and 2018 reported in the National Health Insurance Research Database in Taiwan were obtained. The effect of hospice and palliative care enrollment at different timepoints before death on healthcare utilization was explored. This retrospective cohort study included 605,126 patients diagnosed with terminal cancer between 2005 and 2018; the percentage of patients receiving hospice and palliative care before death increased annually. Terminal cancer patients who enrolled in hospice and palliative care at different timepoints before death received higher total morphine doses; the difference in the total morphine doses between the two groups decreased as the time to death shortened. The difference in the total morphine doses between the groups gradually decreased from 2005 to 2018. The enrolled patients had longer hospital stays; the length of hospital stays for both groups increased as the time to death lengthened, but the difference was not significant. The enrolled patients incurred lower total medical expenses, but the difference between the two groups increased as the time to death shortened.
RESUMEN
This retrospective cohort study aimed to examine the effect of palliative care for patients with terminal cancer on healthcare utilization. The National Health Insurance (NHI) Research Database and death certificates were utilized to identify patients who died of cancer between 2005 and 2018. The number of terminal cancer patients between 2005 and 2018 was 605,126. Propensity score matching and conditional logistic regression were performed. The odds ratios (ORs) for "emergency care utilization", "CPR", "endotracheal intubation", and "ICU admission" were significantly lower for enrolled patients regardless of enrollment time compared to unenrolled patients. Compared to unenrolled patients, the OR for "emergency care utilization" increased from 0.34 to 0.68, the OR for "CPR use" increased from 0.13 to 0.26, the OR for "intubation" increased from 0.15 to 0.26, and the OR for "ICU admission" increased from 0.27 to 0.40 in enrolled patients. Between 2005 and 2010, CPR utilization, intubation, and ICU admission in patients enrolled in palliative care declined each year. Since the inclusion of palliative care in NHI (from 2010 onward), its utilization has increased slightly each year. Patients with terminal cancer enrolled in palliative care consume fewer medical resources before death than unenrolled patients; however, the difference decreases with longer times before death.
RESUMEN
Pay-for-performance (P4P) programs for diabetes care enable the provision of comprehensive and continuous health care to diabetic patients. However, patient outcomes may be affected by the patient's educational attainment. The present retrospective cohort study aimed to examine the effects of the educational attainment of diabetic patients on participation in a P4P program in Taiwan and the risk of dialysis. The data were obtained from the National Health Insurance Research Database of Taiwan. Patients newly diagnosed with type 2 diabetes mellitus (T2DM) aged 45 years from 2002 to 2015 were enrolled and observed until the end of 2017. The effects of their educational attainment on their participation in a P4P program were examined using the Cox proportional hazards model, while the impact on their risk for dialysis was investigated using the Cox proportional hazards model. The probability of participation in the P4P program was significantly higher in subjects with a junior high school education or above than in those who were illiterate or had only attained an elementary school education. Subjects with higher educational attainment exhibited a lower risk for dialysis. Different educational levels had similar effects on reducing dialysis risk among diabetic participants in the P4P program.
RESUMEN
Most patients are diagnosed as having diabetes only after experiencing diabetes complications. Educational attainment might have a positive relationship with diabetes prognosis. The diabetes pay-for-performance (P4P) program-providing comprehensive, continuous medical care-has improved diabetes prognosis in Taiwan. This retrospective cohort study investigated how educational attainment affects the presence of diabetes complications at diabetes diagnosis and mortality risk in patients with diabetes enrolled in the P4P program. From the National Health Insurance Research Database, we identified patients aged >45 years who had received a new diagnosis of type 2 diabetes during 2002-2015; they were followed up until the end of 2017. We next used logistic regression analysis to explore whether the patients with different educational attainments had varied diabetic complication risks at diabetes diagnosis. The Cox proportional hazard model was employed to examine the association of different educational attainments in people with diabetes with mortality risk after their enrollment in the P4P program. The results indicated that as educational attainment increased, the risk of diabetes complications at type 2 diabetes diagnosis decreased gradually. When type 2 diabetes with different educational attainments joined the P4P program, high school education had the highest effect on reducing mortality risk; however, those with ≤ 6th grade education had the lowest impact.

Many adults with diabetes mellitus are unaware worldwide. The study objectives aimed to evaluate the risk of dialysis within 5 years of diagnosis between patients with newly diagnosed diabetes with and without diabetes-related complications. A retrospective longitudinal nationwide cohort study was conducted. Patients diagnosed with diabetes between 2005 and 2013 were followed up until 2018. They were categorized based on the presence or absence of complications, the number of complications, and the diabetes complications severity index (DCSI) scores. Dialysis outcomes were determined through the Registry of Catastrophic Illness from the National Health Insurance Research Database. Among the analyzed patients, 25.38% had complications at diagnosis. Patients with complications at diagnosis had a significantly higher risk of dialysis within 5 years (adjusted hazard ratio: 9.55, 95% confidence interval CI 9.02-10.11). Increasing DCSI scores and the number of complications were associated with higher dialysis risks. Patients with one complication had a 7.26-times higher risk (95% CI 6.83-7.71), while those with ≥ 3 complications had a 36.12-times higher risk (95% CI 32.28-40.41). In conclusion, newly diagnosed diabetes patients with complications face an increased risk of dialysis within 5 years. The severity and number of complications are directly linked to the risk of dialysis within this timeframe.

OBJECTIVE: Cervical cancer is the fourth most prevalent cancer in women worldwide. It is vital to achieve a high cervical cancer screening rate among women. We compared the Pap smear test (PST) used between individuals with disabilities and those without disabilities in Taiwan. METHODS: Individuals registered in the Taiwan Disability Registration File and the National Health Insurance Research Database (NHIRD) were screened for this nationally representative retrospective cohort study. Women aged 30 and above in 2016 and who were still alive in 2016 were matched in a 1:1 ratio via propensity score matching (PSM); 186,717 individuals with disabilities and 186,717 individuals without disabilities were included. Controlling for relevant variables, the odds of receiving PST were compared using conditional logistic regression analysis. RESULTS: A lower percentage of individuals with disabilities (16.93%) received PST than those without disabilities (21.82%). The odds of individuals with disabilities receiving PST were 0.74 times that of individuals without disabilities (OR = 0.74, 95% CI = 0.73-0.76). Compared to individuals without disabilities, individuals with intellectual and developmental disabilities had the lower odds of receiving PST (OR = 0.38, 95% CI = 0.36-0.40), followed by individuals with dementia (OR = 0.40, 95% CI = 0.33-0.48) or multiple disabilities (OR = 0.52, 95% CI = 0.49-0.54). CONCLUSIONS: We highly recommend that healthcare practitioners recognize the unique needs of individuals with different types of disabilities, especially those with cognitive impairments.
RESUMEN
Objective: The difficulties faced by pregnant women with disabilities in accessing health care may make them less likely to receive prenatal care. The aims of this study were to compare the number of prenatal services and the risk of preterm birth between pregnant women with and without disabilities. Methods: A total of 2999 pregnant women aged ≥20 years with birth records in 2011-2014 in Taiwan were enrolled. Data were obtained from the Registration File for Physical and Mental Disabilities and the National Health Insurance Research Database. A 1:4 matching between pregnant women with disabilities and those without disabilities was performed. The logistic regression analysis with generalized estimating equations was used to analyze. Results: The median of prenatal care services used by pregnant women with disabilities was 9.00 (interquartile range, IQR: 2.00). Pregnant women with disabilities used fewer services than those without disabilities (median, 10.00; IQR: 1.00). The disabled group (8.44%) had a significantly higher proportion of preterm births than did the non-disabled group (5.40%). The disabled group was at a 1.30 times higher risk of preterm births than was the non-disabled group. Conclusions: Pregnant women with disabilities used significantly fewer prenatal care services and had a significantly higher risk of preterm birth than pregnant women without disabilities.

To investigate the impact of chronic hepatitis on cardiovascular events in patients with type 2 diabetes mellitus (T2DM). This nationwide retrospective cohort study included 152,709 adult patients (> 20 years) with T2DM enrolled in the National Health Insurance Diabetes Pay-for-Performance Program from 2008 to 2010 and followed up until the end of 2017. Patients were categorized into groups with hepatitis B, hepatitis C, fatty liver disease, and patients without chronic hepatitis. The incidence of cardiovascular events in patients with T2DM and hepatitis C (79.9/1000 person-years) was higher than that in patients with diabetes combined with other chronic hepatitis, or without chronic hepatitis. After adjusting for confounding factors, T2DM with fatty liver (adjusted hazard ratio [HR]: 1.10; 95% confidence interval [CI]: 1.07-1.13) and hepatitis C (adjusted HR: 1.09; 95% CI: 1.03-1.12) demonstrated a significantly higher risk of cardiovascular events. The adjusted visit-to-visit coefficient of variation of HbA1c and fasting blood glucose were associated with a high risk of cardiovascular events (HRs of the highest quartile were 1.05 and 1.12, respectively). Chronic hepatitis affects cardiovascular events in adult patients with T2DM. Glucose variability could be an independent risk factor for cardiovascular events in such patients.

Dysregulation of amyloidogenic proteins and their abnormal processing and deposition in tissues cause systemic and localized amyloidosis. Formation of amyloid ß (Aß) fibrils that deposit as amyloid plaques in Alzheimer's disease (AD) brains is an earliest pathological hallmark. The polysulfated heparan sulfate (HS)/heparin (HP) is one of the non-protein components of Aß deposits that not only modulates Aß aggregation, but also acts as a receptor for Aß fibrils to mediate their cytotoxicity. Interfering with the interaction between HS/HP and Aß could be a therapeutic strategy to arrest amyloidosis. Here we have synthesized the 6-O-phosphorylated HS/HP oligosaccharides and reported their competitive effects on the inhibition of HP-mediated Aß fibril formation inâ vitro using a thioflavin T fluorescence assay and a tapping mode atomic force microscopy.

Because of the difficulties in accessing medical care, the likelihood of receiving breast cancer screening may be low for women with disabilities. We aimed to investigate differences in the utilization of breast cancer screening among women with and without disabilities. Participants included women with and without disabilities from 2004 to 2010, and it was observed whether the participants had received a breast cancer screening during 2011 and 2012. Propensity-score matching was employed to match disabled women with non-disabled women (1:1). Data sources included the National Health Insurance Research Database, the Cancer Screening Database, and the Disability Registration File. Conditional logistic regression was performed to examine the odds ratios (ORs) that both groups would undergo breast cancer screening. The proportion of women with disabilities who received breast cancer screening was 18.33%, which was significantly lower than that of women without disabilities (25.52%) (p < 0.001). Women with dementia had the lowest probability of receiving a mammography examination (OR = 0.34; 95% CI: 0.28−0.43), followed by those with multiple disabilities (OR = 0.43; 95% CI: 0.40−0.47) and intellectual disabilities (OR = 0.45; 95% CI: 0.41−0.50). In conclusion, compared to women without disabilities, those with disabilities were less likely to undergo breast cancer screening.

BACKGROUND: The number of people with disabilities is increasing. People with disabilities are more likely to be physically inactive, which can lead to chronic diseases, including stroke. Stroke is a leading cause of illness and death worldwide, but little is known regarding stroke among people with disabilities. OBJECTIVE: To evaluate the incidence density rate, relative risk, and associated risk factors of stroke and measure the risk of death due to stroke among people with disabilities in Taiwan. METHODS: This retrospective cohort study used nationwide data from the National Health Insurance Research Database, National Disability Registry Database, and Cause of Death File. Incidence density rates of stroke were estimated as new cases per 1000 person-years. Cox proportional hazard models were used to estimate the relative risk of stroke, adjusted survival curves, and adjusted cumulative incidence curves. RESULTS: A total of 670,630 people with disabilities were included in our analyses. The average person-years of observation was 9.43 ± 5.31, with a yearly rate of 16.72 new cases of stroke per 1000 person-years. The highest risk of stroke was found among people with balance disorder (hazard ratio [HR] = 2.27, 95% confidence interval [CI] = 2.00-2.57) and intractable epilepsy (HR = 1.85, 95% CI = 1.56-2.19). The highest risk of death due to stroke was found among people with dementia and multiple disabilities. CONCLUSIONS: Stroke rates were higher among people with disabilities than among the general population, and certain disabilities were associated with a higher stroke risk and death rate.

BACKGROUND: The World Health Organization has recognized that people with disability are among the most marginalized in the world. This study's objective was to investigate the differences in the probability of colorectal cancer (CRC) screening with faecal immunochemical testing (FIT) between people with disability and without disability in Taiwan. METHODS: The study participants included people with and without disability from the Disability Registration Database (2012) and the National Health Insurance Research Database (2009-2012). The study included 50- to 69-year-olds with and without disability who were screened from 2011 to 2012 and were alive in 2012. There were 16 categories of disability. After propensity score matching (PSM) between the two groups, conditional logistic regression analysis with control variables was used to investigate the odds ratio (OR) that people with or without disability would undergo CRC screening. RESULTS: The percentage of people with disability receiving CRC screening was 21.84%, and the highest rate of those receiving CRC screening (38.72%) was found in people with intractable epilepsy, whose OR was 1.47 times that of people with moving functional limitation (95% confidence interval (CI) = 1.17-1.85). The results showed that the probability of CRC screening in people with disability was lower than that in people without disability (OR = 0.88, 95%CI = 0.87-0.89). The probability of receiving CRC screening differed between people with different categories of disability. CONCLUSIONS: Although the probability of CRC screening in the four categories of disability was higher than that in the general population, overall, people with disability were less likely than people without disability to undergo CRC screening. Health inequalities still exist under National Health Insurance in Taiwan.

Oesophageal cancer is the sixth leading cause of cancer death worldwide. This nationwide study analyses the survival results of oesophageal cancer under multidisciplinary team (MDT) care. We enrolled oesophageal cancer patients diagnosed between 2010 and 2015 with follow-up for at least 1 year. This study performed propensity score matching with a ratio of 1:1 between MDT participants and non-MDT participants. We performed conditional Cox proportional hazards model to research relative risk of survival and associated factors of survival. The adjusted survival curves were plotted. 8184 newly diagnosed oesophageal cancer patients were included. The favourable survival factors include participant status of MDT, gender, monthly salary, urbanization level, other catastrophic illness, stage of cancer, treatment methods, and service volume of physicians (P < 0.05). MDT participants showed lower risk of death (HR = 0.73; 95% CI 0.67-0.79). Further stratification analysis revealed that the incorporation of an MDT reduced the death risk of patients with stages 2, 3, and 4 cancer, with the greatest reduction observed in patients with stage 3 cancer (HR = 0.72; 95% CI 0.67-0.79). The risk of death was lower for oesophageal cancer patients who enrolled in MDT care.

BACKGROUND: The diabetes patients enrolled in the pay-for-performance (P4P) program demonstrate reduced risk of death. Body mass index (BMI) is a risk factor of all-cause death. This study investigates the effects of BMI and P4P on the risk of death in type 2 diabetes patients. METHODS: This is a retrospective cohort study. The study population includes the 3-wave National Health Interview Survey in Taiwan. A total of 6354 patients with diabetes aged ≥ 20 years were enrolled and followed up until the end of 2014. RESULTS: The highest mortality rate per 1000 person-years was 61.05 in the underweight patients with diabetes. A lower crude death rate was observed in the P4P participants than non-P4P participants. The risk of death was 1.86 times higher in the underweight patients with diabetes than that in the normal weight group (95% CI: 1.37-2.53) and was lower in the P4P participants, as compared to the non-participants (HR: 0.55, 95% CI: 0.44-0.69). The most significant effect of joining the P4P program in reducing death risk was found in the underweight patients with diabetes (HR: 0.11, 95% CI: 0.04-0.38), followed by the obesity group (HR: 0.30, 95% CI: 0.17-0.52). CONCLUSIONS: Different effects of joining the P4P program on reducing death risk were observed in the underweight and obesity groups. We strongly recommend that patients with diabetes and without healthy BMIs participate in the P4P program.

Human endo-O-sulfatases (Sulf-1 and Sulf-2) are extracellular heparan sulfate proteoglycan (HSPG)-specific 6-O-endosulfatases, which regulate a multitude of cell-signaling events through heparan sulfate (HS)-protein interactions and are associated with the onset of osteoarthritis. These endo-O-sulfatases are transported onto the cell surface to liberate the 6-sulfate groups from the internal d-glucosamine residues in the highly sulfated subdomains of HSPGs. In this study, a variety of HS oligosaccharides with different chain lengths and N- and O-sulfation patterns via chemical synthesis were systematically studied about the substrate specificity of human Sulf-1 employing the fluorogenic substrate 4-methylumbelliferyl sulfate (4-MUS) in a competition assay. The trisaccharide sulfate IdoA2S-GlcNS6S-IdoA2S was found to be the minimal-size substrate for Sulf-1, and substitution of the sulfate group at the 6-O position of the d-glucosamine unit with the sulfonamide motif effectively inhibited the Sulf-1 activity with IC50 = 0.53 µM, Ki = 0.36 µM, and KD = 12 nM.

We aimed to assess the risk of oral cancer incidence in a high-risk population, establish a predictive model for oral cancer among these high-risk individuals, and assess the predictive ability of the constructed model. Individuals aged ≥30 years who had a habit of smoking or betel nut chewing and had undergone oral cancer screening in 2010 or 2011 were selected as study subjects. The incidence of oral cancer among the subjects at the end of 2014 was determined. The annual oral cancer incidence among individuals with a positive screening result was 624 per 100,000 persons, which was 6.5 times that of the annual oral cancer incidence among all individuals screened. Male sex, aged 45-64 years, divorce, low educational level, presence of diabetes, presence of other cancers, high comorbidity severity, a habit of smoking or betel nut chewing, and low monthly salary were high-risk factors for oral cancer incidence (p < 0.05). The area under the curve of the predictive model for oral cancer incidence was 0.73, which indicated a good predictive ability. Therefore, the oral cancer screening policy for the high-risk population with a habit of smoking and/or betel nut chewing is beneficial for the early diagnosis of oral cancer.

PURPOSE: Although nonenzyme-inducing antiepileptic drugs (nEIAEDs) are accepted for the treatment of epilepsy, few studies have examined the costs, benefits, and cost-effectiveness of nEIAEDs in relation to the incidence of fracture among patients with epilepsy. In the present study, we performed cost-benefit and cost-effectiveness analyses comparing the influence of enzyme-inducing AEDs (EIAEDs) and nEIAEDs on the risk of fracture in this population. METHODS: A total of 4864 patients with epilepsy were classified into EIAED and nEIAED groups. Propensity score matching was applied to reduce the influence of selection bias. Clinical outcomes were measured in relation to AED fee, medical expenses associated with epilepsy and fracture, and the total number of fractures. Cost-benefit and cost-effectiveness analyses were performed for all patients. RESULTS: Patients in the unmatched EIAED cohort (nâ¯=â¯3686) were older and had more comorbidities. After matching, the cohorts exhibited similar features (nâ¯=â¯2432 each). Fracture risk was lower in the nEIAED group than in the EIAED group (HRâ¯=â¯0.70). The additional medical expense of nEIAEDs in fractures and epilepsy for 2â¯years per person was 107,731 New Taiwan dollars (NT$). The additional cost for nEIAEDs to reduce one event of fracture was $14,789,421 NT$. CONCLUSIONS: Patients with epilepsy using nEIAEDs had a lower risk of fracture than those using EIAEDs. However, the cost-benefit ratio and cost-effectiveness of such treatment were lower in the nEIAED group than in the EIAED group.

Cancer treatment with antibodies (Abs) is one of the most successful therapeutic strategies for obtaining high selectivity. In this study, α-gal-Ab conjugates were developed that dramatically increased cellular cytotoxicity by recruiting natural Abs through the interaction between α-gal and anti-gal Abs. The potency of the α-gal-Ab conjugates depended on the amount of α-gal conjugated to the antibody: the larger the amount of α-gal introduced, the higher the level of cytotoxicity observed. The conjugation of antibodies with an α-gal dendrimer allowed the introduction of large amounts of α-gal to the Ab, without loss of affinity for the target cell. The method described here will enable the re-development of Abs to improve their potency.

Patients with diabetes are at a high risk of lower extremity amputations and may have a reduced life expectancy. Taiwan has implemented a diabetes pay-for-performance (P4P) program providing team care to improve the control of disease and avoid subsequent complications. Few studies investigated the effects of adopting a nationalized policy to decrease amputation risk in diabetes previously. Our study aimed to analyze the impact of the P4P programs on the incidence of lower extremity amputations in Taiwanese patients with diabetes.This was a population-based cohort study using the Taiwan National Health Insurance Research Database (which provided coverage for 98% of the total population in Taiwan) from 1998 to 2007. Patients with diabetes were identified based on the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnostic codes. We linked procedure codes to inpatient claims to identify patients hospitalized for nontraumatic lower extremity amputations.A total of 9738 patients with diabetes with amputations were enrolled (mean age ± standard deviation: 64.4â±â14.5 years; men: 63.9%). The incidence of nontraumatic diabetic lower extremity amputations decreased over the time period studied (3.79-2.27 per 1000 persons with diabetes). Based on the Cox proportional hazard regression model, male sex (hazard ratio: 1.83, 95% confidence interval [CI] 1.76-1.92), older age, and low socioeconomic status significantly interact with diabetes with respect to the risks of amputation. Patients who did not join the P4P program for diabetes care had a 3.46-fold higher risk of amputation compared with those who joined (95% CI 3.19-3.76).The amputation rate in Taiwanese diabetic patients decreased over the time period observed. Diabetes in patients with low socioeconomic status is associated with an increased risk of amputations. Our findings suggested that in addition to medical interventions and self-management educations, formulate and implement of medical policies, such as P4P program, might have a significant effect on decreasing the diabetes-related amputation rate.
