Cost-effectiveness of diabetic retinopathy screening for newly diagnosed type 2 diabetic patients: A nationwide population-based propensity score-matched cohort study.

AIMS: This study investigated the association between the frequency of screening for diabetic retinopathy (DR) versus the development of DR and corresponding medical expenses among patients newly diagnosed with type 2 diabetes mellitus (T2DM). METHODS: This longitudinal, population-based study used the Taiwan National Health Insurance Research Database (2004 to 2020) as a data source. Propensity score matching (PSM) (sex, age, comorbidities and concurrent medication use) was employed in the grouping of T2DM patients according to different frequency of DR screening. Outcome measures included the proportion of patients who developed DR, who received DR treatment, and the associated medical expenses and hospitalizations. RESULTS: The 17-year cohort included 337,046 patients. After PSM, three groups each containing 35,739 patients were assembled and analyzed. Compared to low-frequency screening, high-frequency screening was more effective in detecting patients requiring treatment; however, the net cost for treatment was significantly lower. Standard-frequency screening appears to provide the best balance in terms of DR detection, diagnosis interval, the risk of DR-related hospitalization, and DR treatment costs. CONCLUSIONS: In this real-world cohort study covering all levels of the healthcare system, infrequent screening was associated with delayed diagnosis and elevated treatment costs, while a fundus screening interval of 1-2 years proved optimal in terms of detection and medical expenditures.

The association between comprehensive patient-centered care and health-related quality of life (HRQoL) for patients with chronic viral hepatitis-A pathway analysis.

BACKGROUND: Patient-centered care (PCC) is a crucial objective for enhancing healthcare in the 21st century. PCC has demonstrated effectiveness in caring for patients with chronic conditions. However, the process from PCC to patient outcomes has not been thoroughly studied, particularly for patients with chronic hepatitis. OBJECTIVE: To investigate the relationship between PCC and the outcomes of hepatitis patients and determine the key mediator in the connection between PCC and outcomes. METHODS: A cross-sectional study was conducted from October to December 2016 in four hospitals in northern Taiwan. Patients with chronic viral hepatitis were assessed for five PCC factors: autonomy support, goal setting, coordination of care, information/education/communication, and emotional support. Trust in the physician, patient adherence, and patient activation (PA) were selected as mediators, with health-related quality of life (HRQoL) as the patient outcome. Pathway analysis was applied to examine the correlation. RESULTS: In total, 496 chronic hepatitis patients were included in the study. The pathway analysis revealed that autonomy support (ß = 0.007, p = 0.011), information/education/communication (ß = 0.009, p = 0.017), and emotional support (ß = 0.001, p = 0.011) correlated with better HRQoL. The effects of PCC factors are fully mediated by trust in physicians, patient adherence, and PA. Among them, PA is the key factor in the process of PCC. CONCLUSION: For chronic viral hepatitis care, PCC should be introduced into clinical practice for better HRQoL, and PA is a key mediator.

Bibliometric and Visualized Analysis of Good Death Research from 2001-2021.

Quantitative analysis via bibliometric field analyses is a recent, gradually emerging method. We conducted a bibliometric study to investigate the authors' scientific influence and contributions and evaluate trends and research foci in good death-related literature using the Web of Science (WOS) Core Collection. A total of 1,157 publications were selected for the analysis. There was a significant increase in annual publications per year (R2 = 0.79). The publication (317, 27.4%) and average citation (29.2) numbers were highest in the USA. Controlling for population number and GDP, the Netherlands had the highest number of articles per million persons (5.89) and US$ 1010 GDP (1.02). North American and Western European countries are leaders in the field, but some East Asian countries (Japan and Taiwan) perform well. Current research focuses on patient perspectives of good death and advance care planning among patients, families, and health care providers.

Advance Care Planning Among Adult Patients and Their End-of-Life Care Preferences.

To explore people's intentions to opt for a good death when planning for their end-of-life care, this study examined the type of end-of-life care preferred by patients receiving advance care planning (ACP) consulting services for five specified clinical and disability conditions and possible factors affecting their decision-making. This cross-sectional study analyzed 1303 hospital patients and 1032 nonhospital patients who attended a clinic providing ACP consulting services. This study revealed the following two results. First, patients who were older, were female, did not have an appointed surrogate decision-maker, and were nonhospital patients had a higher intention of not receiving life-sustaining treatments (LST) or artificial nutrition and hydration (ANH) under the five specified clinical and disability conditions. Second, people who were the least willing to receive LST or ANH under the following conditions (in descending order): permanent vegetative state, severe dementia, irreversible coma, other disease conditions recognized by the central competent authority, and end-of-life stage.

The effect of a pay-for-performance program on health-related quality of life for patients with hepatitis in Taiwan.

PURPOSE: Chronic viral hepatitis is a major global public health problem. The guidelines suggest the long-term performance of regular ongoing liver examinations to monitor liver inflammation and screen for hepatocellular carcinoma. However, the effects of regular liver examinations on health-related quality of life (HRQoL) have not been adequately evaluated. Therefore, this study evaluated the effects of regular ongoing examinations on the quality of life of patients with hepatitis. METHODS: A cross-sectional study was conducted from October to December 2016 in four hospitals in northern Taiwan. A hepatitis pay-for-performance (P4P) program was launched in 2010 to ensure that hepatitis patients have regular ongoing liver examinations. The study group consisted of patients who joined and stayed in the program for more than one year. The study assessed HRQoL utilizing the five-level version of the EuroQol-5 Dimension (EQ-5D-5L) and the EuroQoL visual analog scale (EQ-VAS). The responses for the EQ-5D-5L in hepatitis patients were transformed into the EQ-5D index according to the Taiwanese population's value set. Sociodemographic and clinical characteristics were collected by questionnaire, and descriptive statistics were presented. A two-part model and generalized linear model with a Poisson distribution and a log link function, respectively, were used to examine the associations of the EQ-5D index and EQ-VAS score with participation in the hepatitis P4P program. We applied propensity score weighting with inverse probability weighting to control for selection bias. RESULTS: In all, 508 patients (aged 57.6 ± 11.6 years; 60.8% male) were enrolled in this study. The mean (standard deviation, SD) reported EQ-5D index and EQ-VAS scores were 0.93 (0.12) and 75.1 (13.8), and the median (interquartile range, IQR) values were 1 (0.108) and 80 (15), respectively. The study group had a moderately significantly higher EQ-VAS score (mean ratio = 1.029, P < 0.001). However, the differences in the EQ-5D index scores between the study and control groups were not significant. CONCLUSION: Patients with hepatitis partially benefited from receiving hepatitis P4P in Taiwan, which featured regular ongoing liver examinations, in that their EQ-VAS scores were enhanced but not their EQ-5D index scores.

Metformin, Statin Use, and Female Colorectal Cancer: A Population-Based Cohort Study in Taiwan.

In the last few years, the incidence of colorectal cancer (CRC) in women has gradually increased. However, epidemiological studies on the relationship between type II diabetes mellitus (T2DM) and female CRC and the effect of metformin or statins on female CRC are insufficient. To determine their association, we conducted a population-based cohort study on women in Taiwan. We collected data on a total of 396,521 women aged 40 to 64 years old from 1 January 2007 to 31 December 2009 from the National Health Insurance Research Database. We followed up on all participants in the cohort until the occurrence of CRC, the date for all death, or 31 December 2015. Full development of CRC was identified using the International Classification of Disease (ICD), 9th Revision, code 153. We estimated hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) using the Cox proportional hazards model. Both metformin (adjusted hazard ratio, aHR = 1.12; 95% CI: 0.934-1.335, p = 0.227) and statin (aHR = 1.03; 95% CI: 0.906-1.172, p = 0.645) use showed no association with female CRC in a multivariate analysis. The findings indicate that metformin and statin use showed no protective effect against female colorectal cancer (CRC). An additional randomized trial is necessary to investigate the effect of metformin and statin use in CRC prevention.

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.

Clinical Benefits and Challenges in Application of Novel Portable Gastric Capsule Endoscopy for Home Healthcare Patients.

Portable magnetic-assisted capsule endoscopy (MACE) provides satisfactory patient experience and safety with comparable performance in diagnosis of organic lesions when compared to conventional upper gastrointestinal endoscopy. In this study, a total of 58 homecare patients were included for MACE either in the hospital (n = 42) or at home (n = 16), with mean age of 71.1 ± 12.4 years. A total of 55 patients (94.83%) had completed the MACE with diagnosis of reflux esophagitis (43.6%), gastritis (54.5%), erosions (21.8%), fundic polyps (14.5%), peptic ulcers (25.9%), etc. Most patients (n = 47, 85.5%) were satisfied with the experience, and all patients who received MACE at home (n = 15, 100%) appreciated the convenience of endoscopy at home. Less than half of the patients (n = 24, 43.6%) could afford MACE if the expense was not covered by health insurance (USD 714). Time consumption from both traffic and capsule manipulation was also challenging for the physicians, as it took an average of 24.7 min to complete MACE, but it added up to a total of 92.7 min at home, which is about 15 times that of conventional endoscopy in hospital. More efforts are needed to ease the financial burden of patients, and optimization of workflow in community practice may help lift the obstacles revealed in this study.

Reducing Medication Problems among Minority Individuals with Low Socioeconomic Status through Pharmacist Home Visits.

Introduction: In this study, pharmacists conducted home visits for individuals of medically underserved populations in Taiwan (i.e., socioeconomically disadvantaged individuals, middle-aged or older adults, and individuals living alone, with dementia, or with disabilities) to understand their medication habits. We quantified medication problems among various groups and investigated whether the pharmacist home visits helped to reduce the medication problems. Materials and Methods: From April 2016 to March 2019, pharmacists visited the homes of the aforementioned medically underserved individuals in Taipei to evaluate their drug-related problems and medication problems. Age, living alone, diagnoses of dementia or disabilities, and socioeconomic disadvantages contributed significantly to inadequate disease and medical treatment knowledge and self-care skills as well as lifestyle inappropriateness among patients. The patients who were living alone and socioeconomically disadvantaged stored their drugs in inappropriate environments. Results: After the pharmacists visited the patients' homes twice, the patients improved considerably in their disease and medical treatment knowledge, self-care skills, and lifestyles (p < 0.001). Problems related to the uninstructed reduction or discontinuation of drug use (p < 0.05) and use of expired drugs (p < 0.001) were also mitigated substantially. Discussion and conclusion: Through the home visits, the pharmacists came to fully understand the medicine (including Chinese medicine) and health food usage behaviors of the patients and their lifestyles, enabling them to provide thorough health education. After the pharmacists' home visits, the patients' drug-related problems were mitigated, and their knowledge of diseases, drug compliance, and drug storage methods and environments improved, reducing drug waste. Our findings can help policymakers address the medication problems of various medically underserved groups, thereby improving the utilization of limited medical resources.

Exploratory Study of Palliative Care Utilization and Medical Expense for Inpatients at the End-of-Life.

BACKGROUND: Previous research mostly analyzed the utilization of palliative care for patients with cancer, and data regarding non-cancer inpatients are limited. OBJECTIVES: This research aimed to investigate the current situation regarding palliative care and the important factors that influence its utilization by inpatients (including inpatients with and without cancer) at the end of their lives. We also explored the feasibility of establishing a prediction model of palliative care utilization for inpatients at the end of their lives. These findings will allow medical staff to monitor and focus on those who may require palliative care, resulting in more end-of-life patients receiving palliative care and thereby reducing medical expense and improving their quality of life. METHODS: This was a retrospective study based on real-world health information system (HIS) data from 5 different branches of Taipei City Hospital between 1 January 2018 and 31 December 2018 that enrolled a total of 1668 deceased inpatients. To explore palliative care utilization at the end of life, we used 5-fold cross-validation in four different statistical models to obtain the performance of predictive accuracy: logistic regression (LGR), classification and regression tree (CART), multivariate adaptive regression spline (MARS), and gradient boosting (GB). The important variables that may affect palliative care utilization by inpatients were also identified. RESULTS: The results were as follows: (1) 497 (29.8%) inpatients received palliative care; (2) the average daily hospitalization cost of patients with cancer who received palliative care (NTD 5789 vs. NTD 12,115; p ≤ 0.001) and all patients who received palliative care (NTD 91,527 vs. NTD 186,981; p = 0.0037) were statistically significantly lower than patients who did not receive palliative care; (3) diagnosis, hospital, and length of stay (LOS) may affect palliative care utilization of inpatient; diagnosis, hospitalization unit, and length of hospitalization were statistically significant by LGR; (4) 51.5% of patients utilized palliative consultation services, and 48.5% utilized palliative care units; and (5) MARS had the most consistent results; its accuracy was 0.751, and the main predictors of palliative care utilization are hospital, medical expense, LOS, diagnosis, and Palliative Care Screening Tool-Taiwan version (TW-PCST) scores. CONCLUSIONS: The results reveal that palliative care utilization by inpatients remains low, and it is necessary to educate patients without cancer of the benefits and advantages of palliative care. Although data were limited, the predictability of the MARS model was 0.751; a better prediction model with more data is necessary for further research. Precisely predicting the need for palliative care may encourage patients and their family members to consider palliative care, which may balance both physical and mental care. Therefore, unnecessary medical care can be avoided and limited medical resources can be allocated to more patients in need.

Exploring the Workplace Bullying of Indonesian Caregivers and Its Influencing Factors in Taiwan.

Background: Bullying can pose a risk to the health and safety of humans, including the risk of damage to the emotional, psychosocial, mental, or physical health of employees in the workplace. In this study, we aimed to understand the personal characteristics, mental health, sleep quality, and workplace bullying status of Indonesian caregivers and explore the influencing factors of workplace bullying among them. Methods: This cross-sectional study was based on a structured questionnaire in Indonesian, which was designed to collect the data of essential personal characteristics, workplace bullying, sleep quality, and mental health using the Indonesian versions of the Negative Acts Questionnaire−Revised (NAQ-R), Pittsburgh Sleep Quality Index (PSQI), and the Brief Symptoms Rating Scale (BSRS-5). Results: A total of 60.9% of Indonesian caregivers never experienced workplace bullying in Taiwan. A multiple regression analysis revealed that being a household caregiver (ß = 0.14, p = 0.021), sleep quality (ß = 0.18, p = 0.031), and mental health (ß = 0.44, p < 0.001) were significantly correlated with the overall workplace bullying scores of the respondents and revealed that these three variables explained 45% of the variance. Conclusions: Taiwan Indonesian caregivers have a similar workplace bullying rate to Indonesian employees in the workplace. This study indicated the relationships among the workplace bullying of foreign caregivers and demonstrated that being a household caregiver, sleep quality, and mental health were closely related.

Feasibility of Upper Gastrointestinal Examination in Home Care Setting with a Magnetically Assisted Capsule Endoscopy System: A Retrospective Study.

The magnetic assisted capsule endoscope (MACE) with a hand-held magnetic field navigator (MFN) for upper gastrointestinal examination achieved satisfactory results in a healthy volunteer study. We evaluated the feasibility of upper gastrointestinal examination in the home care setting with the MACE system. Home care patients with upper gastrointestinal symptoms that received an MACE exam were enrolled in the study. MACE procedure time; completeness of observation of important anatomical landmarks; endoscopic diagnosis; patient tolerance during the procedure; and patient data, including age, sex, comorbidities, symptoms, body weight, and height, were retrieved from hospital information system for data analysis. A total of 16 participants were enrolled with a mean age 74.3 ± 15.4 years (47 to 99 years). One patient failed to swallow the capsule and was excluded. The average procedure time was 23.7 ± 10.0 min (14.1 to 42.5 min) to complete each endoscopic exam for the remaining 15 patients. The overall maneuverability in the esophagus, stomach, and duodenum was 93.75%, 87.5%, and 75%, respectively. Overall completeness in the aforementioned regions was 93.75%, 81.25%, and 75%, respectively. No severe adverse events were noted. The results clearly demonstrate the promise of using this MACE system to perform endoscopic examination outside the hospital for patients confined to the community and home.

Prevalence and Risk Factors of Metabolic Syndrome among the Homeless in Taipei City: A Cross-Sectional Study.

The safety and health of homeless people are important social issues. Metabolic syndrome (MetS) is a sub-health-risk phenomenon that has been severely aggravated worldwide in recent years. The purpose of this study was to investigate the prevalence and risk factors of MetS among the homeless in Taipei City, Taiwan. In this study, a convenience sampling was conducted at homeless counseling agencies in Taipei City from April 2018 to September 2018. A total of 297 homeless participants were recruited, from whom clinical indicators and questionnaire information were collected. Through statistical verification, analysis of variance (ANOVA), and logistic regression, we found the following main conclusions for homeless adults in Taipei: (1) The prevalence of MetS was estimated to be 53%, with 50% meeting four or more diagnostic conditions. (2) Dyslipidemia (high-density lipoprotein (HDL) deficiency and elevated triglyceride (TG)) showed the strongest association with the prevalence of MetS; more than 83% of people with HDL deficiency or hypertriglyceridemia had MetS. For the patient groups meeting more MetS diagnostic conditions, the values of high-density lipoprotein cholesterol (HDL-C), TG, and total cholesterol (TC) increased significantly. (3) The deterioration of MetS was significantly related to the high prevalence of hyperlipidemia (HL). (4) The homeless who were divorced, separated or widowed were more likely to suffer from MetS.

Investigating Key Factors Related to the Decision of a Do-Not-Resuscitate Consent.

BACKGROUND: The decision to sign a do-not-resuscitate (DNR) consent is critical for patients concerned about their end-of-life medical care. Taiwan's National Health Insurance Administration (NHIA) introduced a family palliative care consultation fee to encourage family palliative care consultations; since its implementation, identifying which families require such consultations has become more important. In this study, the Taiwanese version of the Palliative Care Screening Tool (TW-PCST) was used to determine each patient's degree of need for a family palliative care consultation. OBJECTIVE: This study analyzed factors associated with signing DNR consents. The results may inform family palliative care consultations for families in need, thereby achieving a higher DNR consent rate and promoting the effective use of medical resources, including time, labor, and funding. METHOD: In this retrospective study, logistic regression analysis was conducted to determine which factors affected the DNR decisions of 2144 deceased patients (aged ≥ 20 years), whose records were collected from the Taipei City Hospital health information system from 1 January to 31 December 2018. RESULTS: Among the 1730 patients with a DNR consent, 1298 (75.03%) received family palliative care consultations. The correlation between DNR consent and family palliative care consultations was statistically significant (p < 0.001). Through logistic regression analysis, we determined that participation in family palliative care consultation, TW-PCST score, type of ward, and length of stay were significant variables associated with DNR consent. CONCLUSIONS: This study determined that TW-PCST scores can be used as a measurement standard for the early identification of patients requiring family palliative care consultations. Family palliative care consultations provide opportunities for patients' family members to participate in discussions about end-of-life care and DNR consent and provide patients and their families with accurate medical information regarding the end-of-life care decision-making process. The present results can serve as a reference to increase the proportion of patients willing to sign DNR consents and reduce the provision of ineffective life-prolonging medical treatment.

The Effects of Obesity-Related Anthropometric Factors on Cardiovascular Risks of Homeless Adults in Taiwan.

Homelessness is a pre-existing phenomenon in society and an important public health issue that national policy strives to solve. Cardiovascular disease (CVD) is an important health problem of the homeless. This cross-sectional study explored the effects of four obesity-related anthropometric factors-body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR)-on cardiovascular disease risks (expressed by three CVD markers: hypertension, hyperglycemia, and hyperlipidemia) among homeless adults in Taipei and compared the relevant results with ordinary adults in Taiwan. The research team sampled homeless adults over the age of 20 in Taipei City in 2018 and collected 297 participants. Through anthropometric measurements, blood pressure measurements, and blood tests, we calculated the obesity-related indicators of the participants and found those at risks of cardiovascular disease. The results showed that the prevalence of hypertension, hyperglycemia, and hyperlipidemia in homeless adults was significantly higher than that of ordinary adults in Taiwan. Among the four obesity-related indicators, WHtR showed the strongest association with the prevalence of hypertension and hyperlipidemia, followed by WHR, both of which showed stronger association than traditional WC and BMI indicators. It can be inferred that abdominal obesity characterized by WHtR is a key risk factor for hypertension and hyperlipidemia in homeless adults in Taiwan. We hope that the results will provide medical clinical references and effectively warn of cardiovascular disease risks for the homeless in Taiwan.

A Worldwide Bibliometric Analysis of Publications on Advance Care Planning in the Past 3 Decades.

BACKGROUND: In recent decades, issues related to end-of-life care and advance care planning (ACP) have attracted popular attention. Advance care planning has been broadly discussed as one of the potential solutions to protect a patient's rights, autonomy, and dignity at the end of life. To better understand publishing on this topic, we conducted this study to demonstrate the worldwide research productivity, trends, and citations of ACP in the past 3 decades by bibliometric analysis. METHODS: Articles published on ACP were retrieved from the Web of Science Core Collection database, and the subject terms included "advance directive," or "advance care planning." RESULTS: Overall, 2126 publications on ACP were retrieved until January 22, 2019. North America, Western Europe, and Australia were the most productive regions. The top 15 countries published 95.9% of the total number of articles. The United States accounted for approximately three-fifths (61.0%) of all publications. When adjusted for population size, Australia had the highest number of articles per million persons (6.64), followed by the Netherlands (6.14) and Belgium (4.61). The most productive authors were Sudore (n = 37), Deliens (n = 29), and Green (n = 24). CONCLUSIONS: The current study revealed that research in terms of publications on ACP has rapidly increased over the past 3 decades. Developed countries, especially the United States, were more concerned with the ACP research field than developing countries were.

Prediction of Recurrence-associated Death from Localized Prostate Cancer with a Charlson Comorbidity Index-reinforced Machine Learning Model.

Research has failed to resolve the dilemma experienced by localized prostate cancer patients who must choose between radical prostatectomy (RP) and external beam radiotherapy (RT). Because the Charlson Comorbidity Index (CCI) is a measurable factor that affects survival events, this research seeks to validate the potential of the CCI to improve the accuracy of various prediction models. Thus, we employed the Cox proportional hazard model and machine learning methods, including random forest (RF) and support vector machine (SVM), to model the data of medical records in the National Health Insurance Research Database (NHIRD). In total, 8581 individuals were enrolled, of whom 4879 had received RP and 3702 had received RT. Patients in the RT group were older and exhibited higher CCI scores and higher incidences of some CCI items. Moderate-to-severe liver disease, dementia, congestive heart failure, chronic pulmonary disease, and cerebrovascular disease all increase the risk of overall death in the Cox hazard model. The CCI-reinforced SVM and RF models are 85.18% and 81.76% accurate, respectively, whereas the SVM and RF models without the use of the CCI are relatively less accurate, at 75.81% and 74.83%, respectively. Therefore, CCI and some of its items are useful predictors of overall and prostate-cancer-specific survival and could constitute valuable features for machine-learning modeling.

Dialysis Membranes Influence Perfluorochemical Concentrations and Liver Function in Patients on Hemodialysis.

Introduction: Perfluoro-octanesulfonate (PFOS) and perfluoro-octanoic acid (PFOA) are two toxic perfluorochemicals (PFCs) commonly used as surfactants. PFCs are difficult to be eliminated from the body. We investigated the influence of different dialysis membranes on the concentrations of PFCs in patients under hemodialysis. Method: We enrolled 98 patients. Of these, 58 patients used hydrophobic polysulfone (PS) dialysis membranes, and the other 40 had hydrophilic membranes made by poly-methyl methacrylate (PMMA) or cellulose triacetate (CTA). Liquid chromatography tandem mass spectrometry coupled was used with isotope dilution to quantify PFOA and PFOS. Results: The predialysis concentrations of PFOA and PFOS in patients with hydrophobic PS dialysis membranes were 0.50 and 15.77 ng/mL, respectively, lower than the concentrations of 0.81 and 22.70 ng/mL, respectively, in those who used hydrophilic membranes (such as CTA or PMMA). Older patients have higher PFOS and poorer body function, with lower Karnofsky Performance Status Scale (KPSS) scores. The demographic data of the two groups were similar. However, patients with hydrophobic PS dialysis membranes had lower predialysis aspartate transaminase (AST) (p = 0.036), lower glucose levels (p = 0.017), and better body function (nonsignificantly higher KPSS scores, p = 0.091) compared with patients who used other membranes. These differences may be associated with the effects of different membranes, because PFOA positively correlated with AST, while PFOS negatively correlated with body function. Conclusions: This is the first study comparing PFC levels in uremic patients with different dialysis membrane. PS membrane may provide better clearance of PFCs and may, therefore, be beneficial for patients.

Associations between perfluorinated chemicals and serum biochemical markers and performance status in uremic patients under hemodialysis.

Perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA) are commonly used perfluorinated chemicals (PFCs). PFCs are mainly excreted by urine. Uremic patients tend to accumulate toxins in their body and have poor functional status. We investigated the associations between PFCs and the clinical profile of uremic patients under hemodialysis (HD). Liquid chromatography tandem mass spectrometry coupled with isotope dilution was used to quantify PFOA and PFOS. We enrolled 126 patients under regular HD. Compared with previous research, the concentration of PFOA was lower, but that of PFOS was higher in uremic patients than in the general population. The levels of PFOA and PFOS in uremic patients before dialysis were 0.52 (ng/ml) and 21.84 (ng/ml) respectively. The PFOA level remained unchanged but that of PFOS decreased to1.85 ng/mL after dialysis. PFOS can be removed by HD. Patients using hypertensive medication had a lower PFOS then those who did not. The PFOS level was negatively correlated with the duration of the HD session and patient performance status, but positively correlated with levels of cholesterol, chloride (an indicator of acidemia), ferritin, and total protein. (p<0.05). The association with serum protein may explain the long half-life of PFCs in humans. This is the first study which investigated PFCs in uremic patients and showed PFCs are associated with adverse effects in this population.

Bibliometric Analysis of Palliative Care-Related Publication Trends During 2001 to 2016.

BACKGROUND: The scientific contributions (publications) and international influence (citations) from authors providing the palliative care (PC)-related literature has a limited number of bibliometric reports. We aimed to analyze PC-related literature using the Institute for Scientific Information Web of Science (WoS) database. METHODS: WoS database was used to retrieve publications with the following key words with title: "palliative care" OR "End of Life care" OR "terminal care.". The statistical analysis of the documents published during 2001 to 2016 was performed. The quantity and quality of research were assessed by the number of total publications and citation analysis. In addition, we also analyzed whether there were possible correlations between publication and socioeconomic factors. RESULTS: The total research output was 6273 articles for PC. There was a 3-fold increase in the number of publications during the period and strong correlation between the year and number of PC-related publications ( R2 = .96). The United States took a leading position in PC research (2448, 39.0%). The highest average citations was reported for the Norway (21.8). Australia had gained the highest productive ability in PC research (24.9 of articles per million populations). The annual impact factor rose progressively with time and increased 1.13 to 2.24 from 2003 to 2016. The number of publications correlated with gross domestic product ( r = .74; P < .001). CONCLUSION: The United States and United Kingdom contributed most of the publications, but some East Asian countries also had a great performance. According to the socioeconomic factors, the publication capacity of top 20 countries is correlated with their economic scale.
