Risk of Atrial Fibrillation in Patients with Different Cancer Types in Taiwan. Life (Basel) 2024; 14:621. [PMID: 38792641 DOI: 10.3390/life14050621] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 05/05/2024] [Accepted: 05/09/2024] [Indexed: 05/26/2024] Open
Abstract
Atrial fibrillation (AF) commonly occurs in approximately 2% of cancer patients, and the incidence of AF among cancer patients is greater than in the general population. This observational study presented the incidence risk of AF among cancer patients, including specific cancer types, using a population database. The Taiwan Cancer Registry was used to identify cancer patients between 2008 and 2017. The diagnosis of AF was based on the International Classification of Diseases codes (ICD-9-CM: 427.31 or ICD-10-CM: I48.0, I48.1, I48.2, and I48.91) in Taiwan national health insurance research datasets. The incidence of developing AF in the cancer population was calculated as the number of new-onset AF cases per person-year of follow-up during the study period. The overall incidence of AF among cancer patients was 50.99 per 100,000 person-years. Patients aged older than 65 years and males had higher AF incidence rates. Lung cancer males and esophageal cancer females showed the highest AF incidence risk (185.02 and 150.30 per 100,000 person-years, respectively). Our findings identified esophageal, lung, and gallbladder cancers as the top three cancers associated with a higher incidence of AF. Careful monitoring and management of patients with these cancers are crucial for early detection and intervention of AF.

Decomposing and simplifying the Fracture Risk Assessment Tool-a module from the Taiwan-specific calculator. JBMR Plus 2024; 8:ziae039. [PMID: 38644977 PMCID: PMC11032218 DOI: 10.1093/jbmrpl/ziae039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 02/26/2024] [Accepted: 03/08/2024] [Indexed: 04/23/2024] Open
Abstract
The Fracture Risk Assessment Tool (FRAX®) is a widely utilized country-specific calculator for identifying individuals with high fracture risk; its score is calculated from 12 variables, but its formulation is not publicly disclosed. We aimed to decompose and simplify the FRAX® by utilizing a nationwide community survey database as a reference module for creating a local assessment tool for osteoporotic fracture community screening in any country. Participants (n = 16384; predominantly women (75%); mean age = 64.8 years) were enrolled from the Taiwan OsteoPorosis Survey, a nationwide cross-sectional community survey collected from 2008 to 2011. We identified 11 clinical risk factors from the health questionnaires. BMD was assessed via dual-energy X-ray absorptiometry in a mobile DXA vehicle, and 10-year fracture risk scores, including major osteoporotic fracture (MOF) and hip fracture (HF) risk scores, were calculated using the FRAX®. The mean femoral neck BMD was 0.7 ± 0.1 g/cm2, the T-score was -1.9 ± 1.2, the MOF was 8.9 ± 7.1%, and the HF was 3.2 ± 4.7%. Following FRAX® decomposition with multiple linear regression, the adjusted R2 values were 0.9206 for MOF and 0.9376 for HF when BMD was included and 0.9538 for MOF and 0.9554 for HF when BMD was excluded. The FRAX® demonstrated better prediction for women and younger individuals than for men and elderly individuals after sex and age stratification analysis. Excluding femoral neck BMD, age, sex, and previous fractures emerged as 3 primary clinical risk factors for simplified FRAX® according to the decision tree analysis in this study population. The adjusted R2 values for the simplified country-specific FRAX® incorporating 3 premier clinical risk factors were 0.8210 for MOF and 0.8528 for HF. After decomposition, the newly simplified module provides a straightforward formulation for estimating 10-year fracture risk, even without femoral neck BMD, making it suitable for community or clinical osteoporotic fracture risk screening.

Inequalities in women's health insurance coverage before and after the implementation of universal health insurance in Indonesia. J Public Health Policy 2024:10.1057/s41271-024-00480-7. [PMID: 38609498 DOI: 10.1057/s41271-024-00480-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/19/2024] [Indexed: 04/14/2024]
Abstract
Indonesia implemented a National Social Security System (Jaminan Kesehatan Nasional, JKN) in 2014. To examine the changes in the magnitude of socioeconomic inequity in women's health insurance coverage among those of reproductive age, we conducted a repeated cross-sectional study design using data from the Indonesia Demographic and Health Surveys conducted in 2012 and 2017, before and after the implementation of JKN. Results showed that while the JKN program helped to increase health insurance coverage among Indonesian women of childbearing age, low education level and household wealth status were associated with an increase in inequalities in health insurance coverage. The findings highlight the need to sustain coverage for citizens and to extend the JKN program to informal workers to reduce health coverage disparities. Further research is required to explore the mechanisms responsible for health coverage inequality based on socioeconomic indicators.

Enhancing indicator condition-guided HIV testing in Taiwan: a nationwide case-control study from 2009 to 2015. BMC Public Health 2024; 24:967. [PMID: 38580963 PMCID: PMC10998297 DOI: 10.1186/s12889-024-18499-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Accepted: 04/02/2024] [Indexed: 04/07/2024] Open
Abstract
BACKGROUND Although indicator condition (IC)-guided HIV testing (IC-HIVT) is effective at facilitating timely HIV diagnosis, research on IC categories and the related HIV risk in Taiwan is limited. To improve the adoption and spread of IC-HIVT in Taiwan, this study compared the IC categories of people living with HIV (PLWH) and non-HIV controls and investigated delays in the diagnosis of HIV infection. METHODS This nationwide, retrospective, 1:10-matched case-control study analyzed data from the Notifiable Diseases Surveillance System and National Health Insurance Research Database to evaluate 42 ICs for the 5-year period preceding a matched HIV diagnostic date from 2009 to 2015. The ICs were divided into category 1 ICs (AIDS-defining opportunistic illnesses [AOIs]), category 2 ICs (diseases associated with impaired immunity or malignancy but not AOIs), category 3 ICs (ICs associated with sexual behaviors), and category 4 ICs (mononucleosis or mononucleosis-like syndrome). Logistic regression was used to evaluate the HIV risk associated with each IC category (at the overall and annual levels) before the index date. Wilcoxon rank-sum test was performed to assess changes in diagnostic delays following an incident IC category by HIV transmission routes. RESULTS Fourteen thousand three hundred forty-seven PLWH were matched with 143,470 non-HIV controls. The prevalence results for all ICs and category 1-4 ICs were, respectively, 42.59%, 11.16%, 15.68%, 26.48%, and 0.97% among PLWH and 8.73%, 1.05%, 4.53%, 3.69%, and 0.02% among non-HIV controls (all P < 0.001). Each IC category posed a significantly higher risk of HIV infection overall and annually. The median (interquartile range) potential delay in HIV diagnosis was 15 (7-44), 324.5 (36-947), 234 (13-976), and 74 (33-476) days for category 1-4 ICs, respectively. Except for category 1 for men who have sex with men, these values remained stable across 2009-2015, regardless of the HIV transmission route. CONCLUSIONS Given the ongoing HIV diagnostic delay, IC-HIVT should be upgraded and adapted to each IC category to enhance early HIV diagnosis.

Trend Analysis of Palliative Care Utilization in Patients with Chronic Obstructive Pulmonary Disease During Hospitalization from 2007 to 2018 in Taiwan. Int J Chron Obstruct Pulmon Dis 2023; 18:3015-3026. [PMID: 38143921 PMCID: PMC10748865 DOI: 10.2147/copd.s435954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 12/10/2023] [Indexed: 12/26/2023] Open
Abstract
Purpose Palliative care utilization among hospitalized patients with advanced chronic obstructive pulmonary disease (COPD) in Taiwan remains low despite its costs making it eligible for reimbursement since 2009. Few studies have examined the trends of palliative care utilization. We analyzed the annual rate, associated factors, and timing of the inpatient palliative care utilization by hospitalized patients with COPD. Patients and Methods We conducted a cross-sectional observational study between 1 January 2007 and 31 December 2018. Population-based claims data were extracted from Taiwan's National Health Insurance Research Database to identify patients aged ≧40 years with COPD five years before the first instance of inpatient palliative care utilization. Results There were 24,502 patients with COPD receiving inpatient palliative care. Our results indicated that older age, concomitant chronic conditions-especially cancer-and severity of comorbidities were associated with a higher rate of palliative care utilization by hospitalized patients with chronic obstructive pulmonary disease. In our study, the proportion of hospitalized patients with COPD receiving inpatient palliative care and having a Charlson comorbidity index score of 1-2 was lower than that of patients with cancer and a Charlson comorbidity index score ≧3 during the 12-year study-observation period. In addition, approximately 50% of hospitalized patients with COPD received palliative care within 18 months after their initial admission for COPD during the study period. However, individuals with a CCI score of 1-2 exhibited a slower entry into palliative care, with nearly 50% initiating it within the first two years. Conclusion Inpatient palliative care utilization by hospitalized patients with advanced COPD remains low due to various causes. Our findings highlight that palliative care may be considered by professional care providers as routine care and as a way to manage problematic symptoms during hospitalization.

Abstract
Introduction This study aimed to investigate the determinants of cancer incidence and mortality in patients with vitamin D deficiency using a real-world population database. Methods We utilized the International Diagnostic Classification Code (ICD9:268 / ICD10: E55) to define patients with vitamin D deficiency. Additionally, the Cox regression model was used to estimate overall mortality and identify potential factors contributing to mortality in cancer patients. Results In 5242 patients with vitamin D deficiency, the development of new-onset cancer was 229 (4.37%) patients. Colon cancer was the most prevalent cancer type. After considering confounding factors, patients aged 50-65 and more than 65 indicated a 3.10-fold (95% C.I.: 2.12-4.51) and 4.55-fold (95% C.I.: 3.03-6.82) cancer incidence, respectively compared with those aged <50. Moreover, patients with comorbidities of diabetes mellitus (DM) (HR: 1.56; 95% C.I.: 1.01-2.41) and liver disease (HR: 1.62; 95% C.I.: 1.03-2.54) presented a higher cancer incidence rate than those without DM/ liver disease. In addition, vitamin D deficiency patients with cancer and dementia histories indicated a significantly higher mortality risk (HR: 4.04; 95% C.I.: 1.05- 15.56) than those without dementia. Conclusion In conclusion, our study revealed that vitamin D deficiency patients with liver disease had an increased incidence of cancer, while those with dementia had an increased mortality rate among cancer patients.

Factors of early breastfeeding initiation among Filipino women: A population-based cross-sectional study. Appl Nurs Res 2023; 74:151732. [PMID: 38007244 DOI: 10.1016/j.apnr.2023.151732] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Revised: 08/03/2023] [Accepted: 08/14/2023] [Indexed: 11/27/2023]
Abstract
BACKGROUND Early breastfeeding initiation (EBI) within the first hour after birth has the potential to reduce neonatal mortality. However, the prevalence of EBI still falls short of the 70 % target set by the WHO for 2030. Limited research has been conducted on this issue. Therefore, the study aimed to assess the prevalence and factors of EBI in the Philippines. METHODS This study is a secondary analysis of the data from the Philippine National Demographic and Health Survey (PNDHS) in 2017. Women survey participants aged 15 to 49 (n = 3750) who had given birth within the two years prior to the survey were included in this study. A p-value < 0.05 was used to define statistical significance when identifying the factors associated with EBI using hierarchical logistic regression analysis. RESULTS Women who were more likely to practice EBI were those from the Cordillera Administrative Region, who read newspaper/magazines, and delivered infants at 2 or later birth order. On the contrary, women from Central Luzon, CALABARZON (Cavite, Laguna, Batangas, Rizal, and Quezon provinces), Central Visayas, Eastern Visayas, and the Autonomous Region of Muslim Mindanao; who listen to the radio at least once a week; and give birth through cesarean section were less likely to practice EBI. CONCLUSION Channeling breastfeeding messages through printed mass media and provision of specialized breastfeeding support to mothers with cesarean section delivery may help in reducing the barriers to early breastfeeding initiation. Targeted interventions and strategies that promote breastfeeding practices, particularly among primigravida women and in regions with lower rates of EBI contribute to increased rate of optimal breastfeeding.

Abstract
CONTEXT Osteoporosis is becoming a global epidemic in aging societies. Anti-osteoporotic medications can prevent fractures, and their pleiotropic effect on mortality is interesting but not well compared among each other. OBJECTIVE To provide real-world evidence on the pleiotropic effect of different anti-osteoporotic medications on all-cause mortality, stratified by fracture site, sex, and age. METHODS This longitudinal population-based postfracture cohort study, included mega-data from subjects ≥40 years of age with osteoporotic fracture who used anti-osteoporotic medications as recorded in Taiwan's National Health Insurance Research Database from 2009 to 2017 and followed until 2018. A multivariate Cox proportional hazards model with immortal time bias was used to assess the relationship between fracture sites and mortality stratified by anti-osteoporosis medication. RESULTS A total of 46 729 subjects with an average age of 74.45 years (80.0% female) and a mean follow-up period of 4.73 years were enrolled. In the total fracture group, compared with raloxifene and bazedoxifene, we found that alendronate/risedronate (hazard ratio [HR] 0.83; 95% CI, 0.79-0.88), denosumab (HR 0.86; 95% CI, 0.81-0.91), and zoledronic acid (HR 0.78; 95% CI, 0.73-0.84) resulted in significantly lower mortality. Similar trends were observed in the hip, vertebral, or nonhip/nonvertebral fracture groups. Subjects receiving long-acting zoledronic acid showed the lowest mortality in the subanalysis according to sex or age over 65 years. CONCLUSION This real-world mega-data study suggests that the usage of osteoporotic medication, especially a long-acting regimen, may lower postfracture mortality.

Abstract
OBJECTIVES Muscle soreness occurs after exercise and also in musculoskeletal diseases, such as fibromyalgia (FM). However, the nosography and pathoetiology of morbid soreness in FM remain unknown. This study aimed to investigate the morbid soreness of FM, evaluate its therapeutic responses and probe its pathophysiology with metabolomics profiling. METHODS Patients with newly diagnosed FM were prospectively recruited and completed self-report questionnaires pertaining to musculoskeletal symptoms. The phenotypes and metabotypes were assessed with variance, classification and correlation analyses. RESULTS Fifty-one patients and 41 healthy controls were included. Soreness symptoms were prevalent in FM individuals (92.2%). In terms of manifestations and metabolomic features, phenotypes diverged between patients with mixed pain and soreness symptoms (FM-PS) and those with pain dominant symptoms. Conventional treatment for FM did not ameliorate soreness severity despite its efficacy on pain. Moreover, despite the salient therapeutic efficacy on pain relief in FM-PS cases, conventional treatment did not improve their general disease severity. Metabolomics analyses suggested oxidative metabolism dysregulation in FM, and high malondialdehyde level indicated excessive oxidative stress in FM individuals as compared with controls (p=0.009). Contrary to exercise-induced soreness, lactate levels were significantly lower in FM individuals than controls, especially in FM-PS. Moreover, FM-PS cases exclusively featured increased malondialdehyde level (p=0.008) and a correlative trend between malondialdehyde expression and soreness intensity (r=0.337, p=0.086). CONCLUSIONS Morbid soreness symptoms were prevalent in FM, with the presentation and therapeutic responses different from FM pain conditions. Oxidative stress rather than lactate accumulation involved phenotype modulation of the morbid soreness in FM. TRIAL REGISTRATION NUMBER NCT04832100.

Abstract
BACKGROUND The patent ductus arteriosus (PDA) treatment in very preterm infants is controversial. This study focused on preterm infants born at 28-32 weeks of gestation and analyzed the association between various PDA treatments and clinical outcomes. METHODS We conducted a retrospective cohort study of infants born at 28-32 weeks of gestation between 2016 and 2019 at 22 hospitals in the Taiwan Premature Infant Follow-up Network. We categorized the infants into four groups according to treatment strategies: medication, primary surgery, medication plus surgery, or conservative treatment. RESULTS A total of 1244 infants presented with PDA, and 761 (61.1%) were treated. Medication was the predominant treatment (50.0%), followed by conservative treatment (38.9%), medication plus surgery (7.6%), and primary surgery (3.5%). The risk of mortality was not reduced in the active treatment group compared to the conservative treatment group. There was a higher prevalence of severe intraventricular hemorrhage, necrotizing enterocolitis (NEC), and any degree of bronchopulmonary dysplasia (BPD) in both the primary surgery and medication plus surgery groups than in the conservative treatment group. After adjustment, both the primary surgery and medication plus surgery groups still had higher odds ratios for the occurrence of NEC and any degree of BPD. CONCLUSIONS Compared with active PDA treatment, conservative treatment for PDA did not increase the risk of mortality and morbidity in very preterm infants born at 28-32 weeks of gestation. The risks and benefits of surgery (PDA ligation) in these infants must be considered cautiously.

Abstract
Background: Lung cancer increases the risk for pulmonary tuberculosis (PTB). The risk factors for newly diagnosed PTB are not known in lung cancer. This study analyzed risk factors of new-onset PTB among lung cancer patients in Taiwan. Methods: Taiwan's National Health Insurance Research Database and Taiwan Cancer Registry were used to define PTB and lung cancer patients between 2007 and 2015. Considering that mortality was a competing risk event during the cancer treatment, Fine and Gray method was performed to estimate the possible risk factors for PTB among lung cancer patients. Results: A total of 1,335 patients had PTB after lung cancer. The incidence of PTB increased with patients' raising age. Males had 1.7-fold (95% CI: 1.5-2.0) risk of PTB compared with females. Patients aged between 60-69 years (HR: 1.4; 95% CI: 1.1-1.8) and those ≥70 years (HR: 1.9; 95% CI: 1.5-2.4) had higher PTB risk than those aged under 50 years. Patients with history of pneumoconiosis and patients who received the treatments of surgery and chemotherapy also had significant increasing risk of PTB. Conclusion: Screening for PTB may be important among lung cancer patients with the aforementioned risk factors.

Abstract
Lung squamous cell carcinoma (LUSC) represents a minor proportion of nonsmall cell lung cancer (NSCLC) harboring a poor prognosis. Herein, retrospective medical record research was performed to investigate real-world treatment patterns and identify the prognostic factors among LUSC patients. A total of 173 patients with a median age of 68 years were enrolled for analysis. Males were predominant (n = 143, 83%) and current or ex-smokers contributed to 78% of the entire cohort. Pleura and lung were the most common metastatic sites, whereas brain metastasis was only 7%. After diagnosis, however, only 107 patients (62%) had received first-line chemotherapy. In the chemotherapy cohort, median progression-free survival (PFS) and overall survival (OS) were 3.9 and 11.1 months, respectively. After multivariable analysis, bone metastasis and the use of first-line single-agent chemotherapy independently predicted shorter PFS. For baseline characteristics, male sex, metastasis to lung, pleura, liver, and bone independently predicted worse OS. Regarding the treatment pattern, patients who had undergone standard first-line doublet therapy and employed targeted therapies after disease progression linked to longer OS. In the real world, even those who underwent chemotherapy still had poor outcome. The findings may help clinicians to orchestrate the treatment strategies for LUSC patients and provide further direction of large-scale studies.

Abstract
Smoking increases the cancer-specific and overall mortality risk in women with breast cancer (BC). However, the effect of smoking cessation remains controversial, and detailed research is lacking in Asia. We aimed to investigate the association between smoking status and mortality in women with BC using the population-based cancer registry. The Taiwan Cancer Registry was used to identify women with BC from 2011 to 2017. A total of 54,614 women with BC were enrolled, including 1687 smokers and 52,927 non-smokers. The outcome, mortality, was identified using Taiwan’s cause-of-death database. The association between smoking status and mortality was estimated using Cox proportional regression. Women with BC who smoked had a 1.25-fold higher (95% C.I.: 1.08–1.45; p = 0.0022) risk of overall mortality and a 1.22-fold higher (95% C.I.: 1.04–1.44; p = 0.0168) risk of cancer-specific mortality compared with non-smokers. The stratified analysis also indicated that women with BC who smoked showed a significantly higher overall mortality risk (HR: 1.20; 95% CI: 1.01–1.43; p = 0.0408) than women with BC who did not smoke among women without comorbidities. Additionally, current smokers had a 1.57-fold higher risk (95% CI: 1.02–2.42; p = 0.0407) of overall mortality compared with ever smokers among women with BC who smoked. It was shown that a current smoking status is significantly associated with an increase in overall and cancer-specific mortality risk in women with BC. Quitting smoking could reduce one’s mortality risk. Our results underscore the importance of smoking cessation for women with BC.

Risk of adverse fetal outcomes following nonobstetric surgery during gestation: a nationwide population-based analysis. BMC Pregnancy Childbirth 2022; 22:406. [PMID: 35562679 PMCID: PMC9102935 DOI: 10.1186/s12884-022-04732-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2021] [Accepted: 04/18/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Literature suggests that nonobstetric surgery during gestation is associated with a higher risk of spontaneous abortion, prematurity, and a higher cesarean section rate, but the direct impact on fetal outcomes is still unclear. In this study, we aimed to investigate whether nonobstetric surgery during pregnancy is associated with negative fetal outcomes by analysing a nation-wide database in Taiwan. METHODS This population-based retrospective observational case-control study was based on the linkage of Taiwan's National Health Insurance Research Database, Birth Reporting Database, and Maternal and Child Health Database between 2004 and 2014. For every pregnancy with nonobstetric surgery during gestation, four controls were randomly matched according to maternal age and delivery year. We estimated adjusted odds ratios (aOR) and 95% confidence intervals (CIs) of adverse fetal outcomes with the non-surgery group as the reference. The primary outcomes involved stillbirth, prematurity, low birth weight, low Apgar scores, and neonatal and infant death. RESULTS Among 23,721 identified pregnancies, 4,747 underwent nonobstetric surgery. Pregnancies with nonobstetric surgery had significantly higher risks of prematurity (aOR: 1.46; 95% CI: 1.31-1.62), lower birth weight (aOR: 1.49; 95% CI: 1.33-1.67), Apgar scores < 7 (1 min, aOR: 1.58; 95% CI: 1.33-1.86; 5 min, aOR: 1.34; 95% CI: 1.03-1.74), neonatal death (aOR: 2.01; 95% CI: 1.18-3.42), and infant death (aOR: 1.69; 95% CI: 1.12-2.54) than those without nonobstetric surgery after adjustment for socioeconomic deprivation, hospital level, and other comorbidities. Surgery performed in the third trimester was associated with a significantly increased rate of prematurity (aOR: 1.38; 95% CI: 1.03-1.85), but lower rates of stillbirth (aOR: 0.1; 95% CI: 0.01-0.75) and Apgar score < 7 at the 5th minute (aOR: 0.2; 95% CI: 0.05-0.82), than surgery performed in the first trimester. CONCLUSIONS Pregnancies with nonobstetric surgery during gestation were associated with increased risks of prematurity, low birth weight, low Apgar scores, neonatal and infant death, longer admission, and higher medical expenses than those without surgery. Furthermore, surgery in the third trimester was associated with a higher rate of prematurity than surgery performed in the first trimester. TRIAL REGISTRATION Not applicable.

Reduced All-Cause Mortality with Bisphosphonates Among Post-Fracture Osteoporosis Patients: A Nationwide Study and Systematic Review. Clin Pharmacol Ther 2022; 112:711-719. [PMID: 35561128 DOI: 10.1002/cpt.2645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Accepted: 05/03/2022] [Indexed: 11/05/2022]
Abstract
We assessed the survival outcomes associated with real-world bisphosphonate use, stratified by fracture site, type, administration, and duration of treatment, among patients with osteoporosis. A systematic review that incorporates our findings was conducted to provide up-to-date evidence on survival outcomes with bisphosphonate treatment in real-world settings. Patients diagnosed with osteoporosis who had been hospitalized for major fractures were identified from Taiwan's National Health Insurance Research Database 2008-2017 and followed until 2018. There were 24,390 new bisphosphonate users who were classified and compared with 76,725 nonusers of anti-osteoporosis medications in terms of survival outcomes using Cox model analysis. An inverse probability of treatment weighted Cox model and landmark analyses for minimizing immortal time bias were also performed. Bisphosphonate users vs. nonusers had a significantly lower mortality risk, regardless of fracture site (hazard ratios (95% confidence intervals) for patients with any major fracture, hip fracture, and vertebral fracture: 0.90 (0.88, 0.93), 0.83 (0.80, 0.86), and 0.86 (0.82, 0.89), respectively). Compared with nonuse, zoledronic acid (0.77 (0.73, 0.82)) was associated with the lowest mortality, followed by ibandronate (0.85 (0.78, 0.93)) and alendronate/risedronate (0.93 (0.91, 0.96)). Using bisphosphonates for ≥ 3 years had lower mortality (0.60 (0.53, 0.67)) than using bisphosphonates for < 3 years (0.98 (0.95, 1.01)). Intravenous bisphosphonates had a lower mortality than that of oral bisphosphonates. Our results are consistent with the systematic review findings among real-world populations. In conclusion, bisphosphonate use, especially persistence to intravenous bisphosphonates (e.g., zoledronic acid), may reduce post-fracture mortality among patients with osteoporosis, particularly those with hip/vertebral fractures. This supports the rational use of bisphosphonates in post-fracture care.

Abstract
OBJECTIVE To examine if the rankings of state HIV age-standardised death rates (SDRs) would be different if different standard populations (SPs) were used when age-specific death rates (ASDRs) in states being compared do not have a consistent relationship. DESIGN A cross-sectional population-based observational study. SETTING 36 states in the USA. PARTICIPANTS Residents living in the 36 states. MAIN OUTCOME MEASURES HIV SDR by state using two SPs, namely US2000 and US2020. RESULTS US HIV ASDR by state did not have consistent relationships. Of 36 states analysed, the HIV death rates of people aged 55-64 years were higher than people aged 45-54 years in 20 states; on the contrary, the HIV death rates of people aged 55-64 years were lower than people aged 45-54 years in 16 states. No change in ranking in 19 states and change in ranking in 17 states. Of the 17 states whose rankings changed, the rankings of 9 states calculated using US2000 were higher (lower SDR) than those calculated using US2020; in 8 states, the rankings were lower (higher SDR). The states with the greatest changes in rankings between US2000 and US2020 were Kentucky (12th and 9th, respectively) and Massachusetts (8th and 11th, respectively). CONCLUSIONS Calculating SDR using elder SP (US2020) would disproportionately increase the SDR in states with peak HIV death rate in older adults than those used younger SP (US2000).

The association between osteoporosis medications and lowered all-cause mortality after hip or vertebral fracture in older and oldest-old adults: a nationwide population-based study. Aging (Albany NY) 2022; 14:2239-2251. [PMID: 35232893 PMCID: PMC8954959 DOI: 10.18632/aging.203927] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Accepted: 02/15/2022] [Indexed: 11/29/2022]
Abstract
Background: Osteoporotic fracture is a common public-health problem in ageing societies. Although post-fracture usage of osteoporosis medications may reduce mortality, recent results have been inconsistent. We aimed to examine associations between osteoporosis medication and mortality in older adults, particularly oldest-old adults (>=85 years old). Methods: Participants aged 65 years old and older newly diagnosed with both osteoporosis and hip or vertebral fractures within 2009-2017 were recruited from the records of 23,455,164 people in Taiwan National Health Insurance Research Database (NHIRD). Osteoporosis medication exposure was calculated after the first-time ambulatory visit with newly diagnosed osteoporosis. Mortality and its specific causes were ascertained from Cause of Death Data. Patients were followed until death or censored at the end of 2018. Results: A total of 87,935 participants aged 65 years old and over (73.4% female), with a mean 4.13 follow-up years, were included. Taking medication was associated with significantly lower risk of mortality (hip fracture HR 0.75, vertebral fracture HR 0.74), even in the oldest-old adults (hip fracture HR 0.76, vertebral fracture HR 0.72), where a longer duration of taking osteoporosis medication was associated with lower all-cause mortality. Specific causes of mortality were also significantly lower for participants taking osteoporosis medication (cancer HR 0.84 in hip fracture, 0.75 in vertebral fracture; cardiovascular disease HR 0.85 in hip fracture, 0.91 in vertebral fracture). Conclusions: Osteoporosis medication after hip or vertebral fracture may reduce mortality risk in older adults, notably in oldest-old adults. Encouraging the use of post-fracture osteoporosis medication in healthcare policies is warranted.

Risk of dementia in colorectal cancer patients receiving chemotherapy: A nationwide cohort study. Cancer Epidemiol 2021; 76:102083. [PMID: 34920341 DOI: 10.1016/j.canep.2021.102083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Revised: 11/29/2021] [Accepted: 12/08/2021] [Indexed: 12/01/2022]
Abstract
BACKGROUND Studies have reported conflicting evidence regarding whether chemotherapy leads to dementia. This study aimed to determine whether chemotherapy increases dementia risk in Taiwanese patients with colorectal cancer (CRC). METHODS Data from the Taiwan Cancer Registry and National Health Insurance Research Database were used. Patients newly diagnosed as having CRC between 2007 and 2015 without prior history of dementia or neurodegenerative disorders were identified. Based on whether they underwent chemotherapy, patients were divided into chemotherapy and non-chemotherapy groups. Those who later developed dementia were identified using validated diagnostic codes. The Fine and Gray subdistribution hazard model for all-cause dementia with competing risk of death was applied for all patients or each stratified group. RESULTS A total of 76,130 patients with CRC were included, with 45,872 (60.25%) in the chemotherapy group and 30,258 (39.75%) in the non-chemotherapy group. A higher incidence of dementia was observed in the non-chemotherapy group compared with the chemotherapy group (3.75% vs. 2.40%, p < 0.0001), but the risk of dementia did not differ between the groups (adjusted subdistribution hazard ratio [HRSD] = 0.97, 95% confidence interval [CI]: 0.88-1.06, p = 0.492). In the stratified analysis, chemotherapy was a risk factor for dementia in patients aged > 80 years (adjusted HRSD = 1.20, 95% CI: 1.03-1.40, p = 0.0190), whereas gender, clinical cancer stage, comorbidities, surgery, and radiation therapy had no impact on the risk of dementia. CONCLUSION Chemotherapy increased the risk of dementia in elderly patients with CRC, highlighting the necessity to monitor their cognitive function after chemotherapy.

Genetic modulation of longitudinal change in neurocognitive function among adult glioma patients. J Neurooncol 2021; 156:185-193. [PMID: 34817796 DOI: 10.1007/s11060-021-03905-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Accepted: 11/17/2021] [Indexed: 11/24/2022]
Abstract
PURPOSE Impaired neurocognitive function (NCF) is extremely common in patients with higher grade primary brain tumor. We previously reported evidence of genetic variants associated with NCF in glioma patients prior to treatment. However, little is known about the effect of genetic variants on NCF decline after adjuvant therapy. METHODS Patients (N = 102) completed longitudinal NCF assessments that included measures of verbal memory, processing speed, and executive function. Testing was conducted in the postoperative period with an average follow up interval of 1.3 years. We examined polymorphisms in 580 genes related to five pathways (inflammation, DNA repair, metabolism, cognitive, and telomerase). RESULTS Five polymorphisms were associated with longitudinal changes in processing speed and 14 polymorphisms with executive function. Change in processing speed was strongly associated with MCPH1 rs17631450 (P = 2.2 × 10-7) and CCDC26 rs7005206 (P = 9.3 × 10-7) in the telomerase pathway; while change in executive function was more strongly associated with FANCF rs1514084 (P = 2.9 × 10-6) in the DNA repair pathway and DAOA rs12428572 (P = 2.4 × 10-5) in the cognitive pathway. Joint effect analysis found significant genetic-dosage effects for longitudinal changes in processing speed (Ptrend = 1.5 × 10-10) and executive function (Ptrend = 2.1 × 10-11). In multivariable analyses, predictors of NCF decline included progressive disease, lower baseline NCF performance, and more at-risk genetic variants, after adjusting for age, sex, education, tumor location, histology, and disease progression. CONCLUSION Our longitudinal analyses revealed that polymorphisms in telomerase, DNA repair, and cognitive pathways are independent predictors of decline in NCF in glioma patients.

Factors Influencing the Compliance of Pregnant Women with Iron and Folic Acid Supplementation in the Philippines: 2017 Philippine Demographic and Health Survey Analysis. Nutrients 2021; 13:nu13093060. [PMID: 34578937 PMCID: PMC8468511 DOI: 10.3390/nu13093060] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Revised: 08/28/2021] [Accepted: 08/30/2021] [Indexed: 11/16/2022] Open
Abstract
Anemia in pregnancy, which is a public health concern for most developing countries, is predominantly caused by iron deficiency. At least, 180 days of iron and folic acid (IFA) supplementation is recommended for pregnant women to mitigate anemia and its adverse effects. This study aimed to examine compliance with the recommendation of IFA supplementation and its underlying factors using the 2017 Philippine National Demographic and Health Survey data. The variables assessed included age, highest level of education, occupation, wealth index, ethnicity, religion, residence, number of pregnancies, time of first antenatal care (ANC) visit and number of ANC visits. Compliance with the recommendation of at least 180 days of IFA supplementation was the outcome variable. The study assessed 7983 women aged 15-49 years with a history of pregnancy. Of these participants, 25.8% complied with the IFA supplementation recommendation. Multiple logistic regression analysis showed that pregnant women of Islamic faith and non-Indigenous Muslim ethnicity were less likely to comply with the IFA supplementation recommendation. Being aged between 25 and 34 years, having better education and higher wealth status, rural residency, initiating ANC visits during the first trimester of pregnancy and having at least four ANC visits positively influenced compliance with IFA supplementation. The effect of residence on IFA adherence differed across the wealth classes. Strategies targeted at specific groups, such as religious minorities, poor urban residents, the less educated and young women, should be strengthened to encourage early and regular antenatal care visits for improving compliance.

Abstract
Introduction Acquired immune deficiency syndrome (AIDS) events at distinct time points after human immunodeficiency virus (HIV) diagnosis require various AIDS prevention strategies. However, no nationwide epidemiological surveillance studies have been conducted to explore the trends of distinct AIDS event time points in various at-risk populations. The aim of this study was to explore the issues and characterize the determinants of AIDS status after HIV diagnosis. Methods This nationwide cohort study enrolled HIV-positive Taiwanese during 1984–2016. AIDS events were classified into three time points (≤ 3, 4–12, > 12 months) by their occurrence time after HIV diagnosis. The periods of HIV/AIDS diagnosis were divided into six categories according to the calendar year of HIV/AIDS diagnosis: 1984–1991, 1992–1996, 1997–2001, 2002–2006, 2007–2011, and 2012–2016. HIV-positive Taiwanese during 1984–2011 were then selected to determine the factors associated with four AIDS statuses within 5 years after HIV diagnosis (no AIDS, AIDS ≤ 3 months, within 4–12 months, > 12 months) using multinomial logistic regression. Results Of 33,142 cases, we identified 15,254 (46%) AIDS events. The overall AIDS incidence (events/100 person-years) peaked during 1992–1996 (20.61), then declined, and finally stabilized from 2002 (8.96–9.82). The evolution of the proportion of distinct time points of AIDS events following HIV diagnosis changed significantly in heterosexuals and intravenous drug users (IDUs) during 1984–2016 (decline at ≤ 3 months in IDUs, decline at 4–12 months in IDUs, and increase at > 12 months in heterosexuals and IDUs) but not among men who have sex with men (MSM). Time points at ≤ 3 months remained at > 50% among MSM and at > 55% among heterosexuals. In multinomial logistic regression, IDUs (vs. men who have sex with men; MSM) had a lower risk of all AIDS statuses; heterosexuals (vs. MSM) had a higher risk of AIDS events ≤ 3 months after HIV diagnosis. Conclusion The magnitude of AIDS in Taiwan has been stable since 2002. Enhancing early diagnosis among people with sexual contact and optimizing the HIV care continuum among heterosexuals and IDUs should be priorities for further AIDS prevention strategies.

Abstract
BACKGROUND To study the distribution of the birthplaces of very-low-birth-weight (VLBW) infants and examine whether delivery at different levels of hospital affects neonatal and infant mortality. METHODS This population-based cohort study was retrieved from Taiwan Maternal and Child Health Database. Livebirth singleton VLBW infants born between 2011 and 2014, with BW between 500 and 1499 g and gestational age ≥22 weeks were enrolled. The main outcomes were risk-adjusted odds ratios (aOR) of neonatal and infant mortality by birthplace, which was categorized as medical center (MC), regional hospital (RH), district hospital (DH), and clinic (C) based on Taiwan's hospital accreditation system. RESULTS Of 4560 VLBW infants enrolled, 3005 (66%) were born in MCs, 1181 (26%) in RHs, 213 (5%) in DHs, and 161 (4%) in Cs. Neonatal mortality rates were 10%, 15%, 16%, 17%, and infant mortality rates were 13%, 17%, 18%, 21%, if born in MCs, RHs, DHs and Cs, respectively. The aORs for neonatal and infant mortality were 1.94 (95% CI 1.53-2.48) and 1.67 (1.34-2.08) for those born in RHs, 2.26 (1.38-3.70) and 1.82 (1.16-2.86) for infants born in DHs/Cs, as compared to those born in MCs. For VLBW infants born in RHs, DHs, and Cs and postnatally transferred to MCs, the aORs of neonatal and infant mortality were lower than those who were not transferred. CONCLUSION VLBW infants born outside of MCs had higher neonatal and infant mortality and a two-fold higher risk of mortality than those born in MCs. When possible, VLBW infants should be born in MCs.

Abstract
Studies from the United States have shown increasing incidence of autism spectrum disorder (ASD) with increasing socioeconomic status (SES), whereas in Scandinavian countries, no such relation was identified. We investigated how ASD risk in offspring varied according to parental SES in Taiwan, where there is universal health care. Through linking birth reporting data and data from Taiwan's national health insurance program, we studied 706,111 singleton births from 2004 to 2007 and followed them until 2015. Parental SES was determined by monthly salary at the time of childbirth, and child neuropsychiatric outcomes were defined using International Classification of Diseases codes. We identified 7,323 ASD cases and 7,438 intellectual disability (ID) cases; 17% of ASD cases had co-occurring ID. In multivariable Cox regression analysis, higher SES was independently associated with higher risk of ASD after we took into account urbanization levels, child sex, parental age, and other covariates. By contrast, higher SES was independently associated with lower risk of ID. Besides the SES disparity in ASD case ascertainment and in the access to health care, findings from Taiwan suggest that other social, environmental, biological, and immunological factors linked with parental SES levels may contribute to the positive relation of SES and ASD risk.

Abstract
Background The expanded definition of liver-related deaths includes a wide range of etiologies and sequelae. We compared the changes in liver-related mortality by etiology and sequelae for different age groups between 2008 and 2018 in the USA using both underlying and multiple cause of death (UCOD and MCOD) data. Methods We extracted mortality data from the CDC WONDER. Both the absolute (rate difference) and relative (rate ratio and 95% confidence intervals) changes were calculated to quantify the magnitude of change using the expanded definition of liver-related mortality. Result Using the expanded definition including secondary liver cancer and according to UCOD data, we identified 68,037 liver-related deaths among people aged 20 years and above in 2008 (29 per 100,000) and this increased to 90,635 in 2018 (33 per 100,000), a 13% increase from 2008 to 2018. However, according to MCOD data, the number of deaths was 113,219 (48 per 100,000) in 2008 and increased to 161,312 (58 per 100,000) in 2018, indicating a 20% increase. The increase according to MCOD was mainly due to increase in alcoholic liver disease and secondary liver cancer (liver metastasis) for each age group and hepatitis C virus (HCV) and primary liver cancer among decedents aged 65–74 years. Conclusion The direction of mortality change (increasing or decreasing) was similar in UCOD and MCOD data in most etiologies and sequelae, except secondary liver cancer. However, the extent of change differed between UCOD and MCOD data.

Abstract
After traumatic brain injury (TBI), an inflammatory response in the brain might affect the immune system. The risk of pulmonary infection reportedly increases in patients with TBI. We aimed to evaluate the risk of tuberculosis (TB) in patients with TBI in Taiwan. All participants were selected from the intensive care unit (ICU). Patients with TBI were defined as patients in ICU with intracranial injury, and comparison cohort were patients in ICU without TBI diagnosis. There was a significant difference in TB risk between the patients with TBI and the comparison cohort according to age and the Charlson’s comorbidity index (CCI) score. Thus, we divided patients based on CCI into three groups for further analysis: mild (CCI = 0), moderate (CCI = 1/2), severe (CCI > 2). Mild-CCI group had a lower TB incidence rate (0.74%) and longer time to TB development (median: 2.43) than the other two groups. Moderate-CCI group had 1.52-fold increased risk of TB infection (p < 0.0001) compared with mild-CCI group. In the severe-CCI group, patients aged ≥ 80 years had 1.91-fold risk of TB compared with mild-CCI group (p = 0.0481). Severe-CCI group had significantly higher mortality than the mild-CCI group (p = 0.0366). Patients with TBI and more comorbidities had higher risk of TB infection with higher mortality rate.

This study aimed to investigate the performance of innovative and traditional cardiometabolic indices, including body mass index (BMI), waist circumference (WC), Chinese visceral adiposity index (CVAI), visceral adiposity index, lipid accumulation product, a body shape index (ABSI), body roundness index, conicity index (CI), triglyceride-glucose (TyG) index, TyG-BMI, and TyG-WC, in estimating atherosclerotic cardiovascular disease (ASCVD) risk in 3143 Taiwanese adults aged 20–79 years. Elevated 10-year ASCVD risk was defined as ≥7.5% using the Pooled Cohort Equations. The performance of different indices in estimating elevated ASCVD risk was assessed by receiver operating characteristic (ROC) curves. In multivariate-adjusted logistic regression analyses, all cardiometabolic indices (p-value < 0.001) were significantly associated with elevated ASCVD risk in both genders, except for ABSI and CI in women. In particular, CVAI had the largest area under the curve (AUC) in men (0.721) and women (0.883) in the ROC analyses. BMI had the lowest AUC in men (0.617), while ABSI had the lowest AUC in women (0.613). The optimal cut-off value for CVAI was 83.7 in men and 70.8 in women. CVAI performed best among various cardiometabolic indices in estimating elevated ASCVD risk. CVAI may be a reliable index for identifying people at increased risk of ASCVD.

Existing Data Sources in Clinical Epidemiology: The Taiwan National Health Insurance Laboratory Databases. Clin Epidemiol 2021; 13:175-181. [PMID: 33688263 PMCID: PMC7935352 DOI: 10.2147/clep.s286572] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Accepted: 01/30/2021] [Indexed: 01/28/2023] Open
Abstract
This paper provides an introduction to laboratory databases established by Taiwan National Health Insurance Administration (NHIA) since 2015 and released for research since June 2017. The National Health Insurance (NHI) is a government-run single-payer program introduced in 1995 that now covers more than 99% of 23 million Taiwanese citizens. To prevent duplication of medication prescriptions and laboratory test and examination prescriptions, contracted health care providers are required to upload the results of laboratory tests and reports of examinations to the NHIA. The cumulative number of laboratory test results was 5.64 billion from January 2015 to the end of August 2020 for 602 types of test. There are 35 variables for each laboratory test result stored in the databases that can be used for research. However, different hospitals might use different format in reporting the results. The researchers therefore have to develop algorithms to include and exclude incompatible records and to determine whether the results are positive or negative (normal or abnormal). The NHIA suggests that researchers release their source codes of algorithms so that other researchers can modify the codes to improve inter-study comparability. Through the unique personal identification number, the laboratory data can be linked to NHI inpatient and outpatient claims data for further value-added analyses. Non-Taiwanese researchers can collaborate with Taiwan researchers to access the NHI laboratory databases.

Hepatitis C virus infection mortality trends according to three definitions with special concern for the baby boomer birth cohort. J Viral Hepat 2021; 28:317-325. [PMID: 33141497 DOI: 10.1111/jvh.13436] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 10/20/2020] [Accepted: 10/23/2020] [Indexed: 12/31/2022]
Abstract
We examined mortality trends of hepatitis C virus (HCV) infection in the United States in 1999-2018 according to the following definitions: HCV as the underlying cause of death (UCOD), HCV mentioned anywhere on the death certificate (mentioned), and HCV recorded in Part 1 of the death certificate. By using entity axis information in mortality multiple-cause files, we ascertained the position of HCV on the death certificate. Joinpoint regression analysis was used to evaluate changes in HCV mortality rates according to the definitions. The age-standardized HCV mortality rates (deaths per 100,000 people) in terms of UCOD, mentioned, and Part 1 were, respectively, 1.36, 2.87 and 1.94, in 1999; increased to 1.90, 5.09 and 2.96 in 2013; and declined to 0.98, 3.77 and 2.29 in 2018. The mentioned/UCOD mortality ratio was 2.11 in 1999 and increased to 3.86 in 2018. The mentioned/Part 1 ratio was almost identical (ie 1.48 in 1999 and 1.65 in 2018). The extent of decline from 2014 to 2018 differed according to the definitions; the annual per cent changes for UCOD, mentioned, and Part 1 were -14.6%, -7.1% and -9.8%, respectively. For the same age group, the baby boomer subcohort 1950-1954 had the highest mortality rates among the subcohorts (1945-1949, 1955-1959 and 1960-1964). HCV mortality according to HCV in Part 1 of the death certificate-the explicit opinion of a certifying physician that HCV played a substantial role and directly caused death-differed from that according to HCV as UCOD and HCV mentioned.

Abstract
Purpose Influenza virus infection is associated with a high disease burden. COVID-19 caused by SARS-CoV-2 has become a pandemic outbreak since January 2020. Taiwan has effectively contained COVID-19 community transmission. We aimed to validate whether fighting COVID-19 could help to control other respiratory infections in Taiwan. Method We collected week-case data of severe influenza, invasive Streptococcus pneumoniae disease and death toll from pneumonia among 25 calendar weeks of the influenza season for four years (2016–2020), which were reported to Taiwan CDC. Trend and slope differences between years were compared. Result A downturn trend of severe influenza, invasive S. pneumoniae disease and the death toll from pneumonia per week in 2019/2020 season and significant trend difference in comparison to previous seasons were noted, especially after initiation of several disease prevention measures to fight potential COVID-19 outbreak in Taiwan. Conclusions Fighting COVID-19 achieved collateral benefits on significant reductions of severe influenza burden, invasive S. pneumoniae disease activity, and the death toll from pneumonia reported to CDC in Taiwan.

Does sex matter? Association of fetal sex and parental age with pregnancy outcomes in Taiwan: a cohort study. BMC Pregnancy Childbirth 2020; 20:348. [PMID: 32513208 PMCID: PMC7282132 DOI: 10.1186/s12884-020-03039-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2019] [Accepted: 05/28/2020] [Indexed: 12/20/2022] Open
Abstract
Background Worldwide several studies have examined the associations of fetal sex, paternal age and maternal age with pregnancy outcomes, with the evidence regarding paternal age being less consistent. Although in Taiwan we keep good records on birth certificates, these issues have been seldom researched. Our objective was to assess the association of fetal sex and parental age with gestational hypertension/preeclampsia, eclampsia and preterm delivery in the Taiwanese population. Methods We conducted a nationwide study and included 1,347,672 live births born between 2004 and 2011 in Taiwan. Gestational hypertension/preeclampsia and eclampsia were ascertained based on the International Classification of Diseases codes; preterm delivery (< 37 weeks) was defined according to the gestational age documented by healthcare providers. We implemented logistic regression models with covariates adjusted to assess the association of fetal sex and parental age with pregnancy outcomes. Results The prevalence was 2.27% for gestational hypertension/preeclampsia, 0.07% for eclampsia and 6.88% for preterm delivery. After considering other parent’s age and covariates, we observed a significantly stepped increase in the risk of both gestational hypertension/preeclampsia and preterm delivery as paternal and maternal age increased. For example, fathers aged ≥50 years were associated with a significantly higher risk of gestational hypertension/preeclampsia (odds ratio [OR]: 1.60, 95% CI: 1.39, 1.84) and preterm delivery (OR: 1.38, 95% CI: 1.27, 1.51) than fathers aged 25–29 years. Analysis on fetal sex showed that relatively more female births were linked to gestational hypertension/preeclampsia and more male births linked to preterm delivery, compared to the whole population. Conclusions We found both paternal and maternal age, as well as fetal sex, were associated with the risk of pregnancy outcomes. Some findings on fetal sex contradicted with previous research using non-Asian samples, suggesting that ethnicity may play a role in the association of fetal sex and pregnancy outcomes. Besides, there is a need to counsel couples who are planning their family to be aware of the influence of both advanced maternal and paternal age on their pregnancy outcomes.

Physician code creep after the initiation of outpatient volume control program and implications for appropriate ICD-10-CM coding. BMC Health Serv Res 2020; 20:127. [PMID: 32075642 PMCID: PMC7031988 DOI: 10.1186/s12913-020-5001-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Accepted: 02/14/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Most studies on the physician code creep (i.e., changes in case mix record-keeping practices to improve reimbursement) have focused on episodes (inpatient hospitalizations or outpatient procedures). Little is known regarding changes in diagnostic coding practices for better reimbursement among a fixed cohort of patients with chronic diseases. METHODS To examine whether physicians in tertiary medical centers changed their coding practices after the initiation of the Outpatient Volume Control Program (OVCP) in Taiwan, we conducted a retrospective observational study of four patient cohorts (two interventions and two controls) from January 2016 to September 2017 in Taiwan. The main outcomes were the number of outpatient visits with four coding practices: 1) OVCP monitoring code recorded as primary diagnosis; 2) OVCP monitoring code recorded as secondary diagnosis; 3) non-OVCP monitoring code recorded as primary diagnosis; 4) non-OVCP monitoring code recorded as secondary diagnosis. RESULTS The percentage change of the number of visits with coding practice 1 between 2016Q1 and 2017Q3 was - 74% for patients with hypertension and - 73% with diabetes in tertiary medical centers and - 23% and - 17% in clinics, respectively. By contrast, the percentage changes of coding practice 3 were + 73% for patients with hypertension and + 46% for patients with diabetes in tertiary medical centers and - 19% and - 2% in clinics, respectively. CONCLUSIONS Physician code creep occurred after the initiation of the OVCP. Education regarding appropriate outpatient coding for physicians will be relatively effective when proper coding is related to reimbursement.

Cataract surgery-related complications in patients with end-stage renal disease- a nationwide population-based study in Taiwan. Sci Rep 2020; 10:2159. [PMID: 32034272 PMCID: PMC7005803 DOI: 10.1038/s41598-020-59160-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2019] [Accepted: 01/21/2020] [Indexed: 11/29/2022] Open
Abstract
This nationwide retrospective case-control study was aimed at elucidating the risk from cataract surgery in end-stage renal disease (ESRD) patients. Cataract surgery patients were identified using the diagnostic and procedural codes for International Classification of Diseases, 9th Revision, Clinical Modification from Taiwan’s National Health Insurance Research Database. ESRD patients were selected as cases, while propensity scores for age, sex, comorbidities and year-of-surgery-matched patients without chronic kidney disease constituted the controls. Patients who had undergone eye surgery within 3 years before cataract surgery were excluded. The main outcome measures were target cataract surgery-related complications within 3 months after surgery. A total of 352 cases and 1,760 controls were analysed. Patients with ESRD had a 5.06-fold (95% CI: 2.36–10.87; p < 0.001) risk of vitreous haemorrhage and a 2.74-fold (95% CI: 1.20–6.27; p = 0.017) risk of re-operation for dropped nucleus or vitreous complications. Non-diabetic ESRD patients had a 3.49-fold (95% CI: 1.36–8.91; p = 0.009) risk of corneal oedema. In conclusion, ESRD patients have a higher risk of vitreous haemorrhage, re-operation for dropped nucleus or vitreous complications and corneal oedema (non-diabetic patients) after cataract surgery. Pre-surgery corneal examination, surgery procedure and medication adjustment, closer and longer post-surgery follow-up may lower the risk and improve the visual outcome.

Abstract
OBJECTIVE To investigate regional variation in the registration of births (still+live) as live born for birth weight <500 g and the impact on the city/county ranking of neonatal mortality rate (NMR) in Taiwan. DESIGN Population-based cross-sectional ecological study. SETTING 20 cities/counties in Taiwan. PARTICIPANTS Registered births for birth weight <500 g and neonatal deaths in 2015-2016. MAIN OUTCOME MEASURES City/county percentage of births <500 g registered as live born and ranking of city/county NMR (deaths per 1000 live births) including and excluding live births <500 g. RESULTS The percentage of births <500 g registered as live born ranged from 0% in Keelung City (0/26) and Penghu County (0/4) to 20% in Taipei City (112/558), 24% in Hsinchu County (5/21) and 28% in Hualien County (9/32). The change in city/county ranking of NMR from including to excluding live births <500 g was most prominent in Taipei City (from the 15th to the 1st) followed by Kaohsiung City (from the 18th to the 14th). CONCLUSIONS The city/county NMR in Taiwan is influenced by variation in the registration of live born for births with uncertain viability. We recommend presenting city/county NMR using both criteria (with or without minimum threshold of gestation period or birth weight) for better interpretation of the findings of comparisons of city/county NMR.

Abstract
BACKGROUND A yearly increase in the proportion of very low birth weight (VLBW) live births has resulted in the slowdown of decreasing trends in crude infant mortality rates (IMRs). In this study, we examined the trends in birth weight-specific as well as birth weight-adjusted IMRs in Taiwan. METHODS We linked three nationwide datasets, namely the National Birth Reporting Database, National Birth Certification Registry, and National Death Certification Registry databases, to calculate the IMRs according to the birth weight category. Trend tests and mortality rate ratios in the periods 2010-2011 and 2004-2005 were used to examine the extent of reduction in birth weight-specific and birth weight-adjusted IMRs. RESULTS The proportion of VLBW (<1500 g) infants among live births increased from 0.78% in 2004-2005 to 0.89% in 2010-2011, thus exhibiting a 15% increase. The extents of the decreases in birth weight-specific IMRs in the 500-999, 1000-1499, 1500-1999, 2000-2499, and 2500-2999 g birth weight categories were 15%, 33%, 43%, 30%, and 28%, respectively, from 2004-2005 to 2010-2011. The reduction in IMR in each birth weight category was larger than the reduction in the crude IMR (13%). By contrast, the IMR in the <500 g birth weight category exhibited a 56% increase during the study period. The IMRs were calculated by excluding all live births with a birth weight of <500 g. The birth weight-adjusted IMRs, which were calculated using a standard birth weight distribution structure for adjustment, exhibited similar extent reductions. CONCLUSION In countries with an increasing proportion of VLBW live births, birth weight-specific or -adjusted IMRs are more appropriate than other indices for accurately assessing the real extent of reduction in IMRs.

Abstract
Background Although many epidemiological studies have presented road traffic injuries (RTIs) according to the victim’s mode of transport, very few have mentioned the mode of transport of the victim’s counterparts. We sought to use matrix frame to present the pattern of RTIs based on the International Classification of Diseases, Tenth Revision (ICD-10) codes. Methods Patients admitted to Hualien Tzu Chi Hospital, Taiwan, for RTIs from January 1, 2013 to December 31, 2016 were included. The numbers and proportions of various crash types of RTIs were presented using a matrix frame. The row margin of the matrix is the second character of ICD-10 codes V00–V79 (victim’s mode of transport), and the column margin of the matrix is the third character of ICD-10 codes V00–V79 (mode of transport of victim’s counterpart), constituting a 80-cell grid. Results In total, 2727 patients were included. The cell with the highest proportion in the matrix grid was ICD-10 code V23 “motorcycle rider injured in collision with car, pick-up truck or van” (27.0%, 737/2727), followed by that of V27 “motorcycle rider injured in collision with fixed or stationary object” (12.5%, 342/2727) and V28 “motorcycle rider injured in noncollision transport accident” (12.2%, 334/2727). The matrix pattern of RTIs differed with sex and age. Conclusions By using the matrix frame, we can easily understand the RTI pattern for different demographic groups and identify the priority crash types.

Abstract
BACKGROUND The association between palliative care and life-sustaining treatments for patients with dementia is unclear in Asian countries. AIM To analyse the use of palliative care and its association with aggressive treatments based on Taiwanese national data. DESIGN A matched cohort study was conducted. The association between intervention and outcome was evaluated using conditional logistic regression analyses. SETTING/PARTICIPANTS The source population comprised 239,633 patients with dementia diagnosed between 2002 and 2013. We selected patients who received palliative care between 2009 and 2013 (the treatment cohort; N = 1996) and assembled a comparative cohort ( N = 3992) through 1:2 matching for confounding factors. RESULTS After 2009, palliative care was provided to 3928 (1.64%) patients of the dementia population. The odds ratio for undergoing life-sustaining treatments in the treatment cohort versus the comparative cohort was <1 for most treatments (e.g. 0.41 for mechanical ventilation (95% confidence interval: 0.35-0.48)). The odds ratio was >1 for some treatments (e.g. 1.73 for tube feeding (95% confidence interval: 1.54-1.95)). Palliative care was more consistently associated with fewer life-sustaining treatments for those with cancer. CONCLUSIONS Palliative care is related to reduced life-sustaining treatments for patients with dementia. However, except in the case of tube feeding, which tended to be provided alongside palliative care regardless of cancer status, having cancer possibly had itself a protective effect against the use of life-sustaining treatments. Modifying the eligibility criteria for palliative care in dementia, improving awareness on the terminal nature of dementia and facilitating advance planning for dementia patients may be priorities for health policies.

Abstract
Traumatic brain injury (TBI) is an important health issue with high mortality. Various complications of physiological and cognitive impairment may result in disability or death after TBI. Grouping of these complications could be treated as integrated post-TBI syndromes. To improve risk estimation, grouping TBI complications should be investigated, to better predict TBI mortality. This study aimed to estimate mortality risk based on grouping of complications among TBI patients. Taiwan's National Health Insurance Research Database was used in this study. TBI was defined according to the International Classification of Diseases, Ninth Revision, Clinical Modification codes: 801-804 and 850-854. The association rule data mining method was used to analyze coexisting complications after TBI. The mortality risk of post-TBI complication sets with the potential risk factors was estimated using Cox regression. A total 139,254 TBI patients were enrolled in this study. Intracerebral hemorrhage was the most common complication among TBI patients. After frequent item set mining, the most common post-TBI grouping of complications comprised pneumonia caused by acute respiratory failure (ARF) and urinary tract infection, with mortality risk 1.55 (95% C.I.: 1.51-1.60), compared with those without the selected combinations. TBI patients with the combined combinations have high mortality risk, especially those aged <20 years with septicemia, pneumonia, and ARF (HR: 4.95, 95% C.I.: 3.55-6.88). We used post-TBI complication sets to estimate mortality risk among TBI patients. According to the combinations determined by mining, especially the combination of septicemia with pneumonia and ARF, TBI patients have a 1.73-fold increased mortality risk, after controlling for potential demographic and clinical confounders. TBI patients aged<20 years with each combination of complications also have increased mortality risk. These results could provide physicians and caregivers with important information to increase their awareness about sequences of clinical syndromes among TBI patients, to prevent possible deaths among these patients.

Abstract
OBJECTIVES The aim of this quasi-experimental study was to examine whether high-volume percutaneous coronary intervention (PCI) operators still maintain high volume and quality of outcomes when they moved to lower volume hospitals. BACKGROUND Systematic reviews have indicated that high-volume PCI operators and hospitals have higher quality outcomes. However, little is known on whether high PCI volume and high quality outcomes are mainly due to operator characteristics (i.e., skill and experience) and is portable across organizations or whether it is due to hospital characteristics (i.e., equipment, team, and management system) and is less portable. METHODS We used Taiwan National Health Insurance claims data 2000-2012 to identify 98 high-volume PCI operators, 10 of whom moved from one hospital to another during the study period. We compared the PCI volume, risk-adjusted mortality ratio, and major adverse cardiovascular event (MACE) ratio before and after moving. RESULTS Of the 10 high-volume operators who moved, 6 moved from high- to moderate- or low-volume hospitals, with median annual PCI volumes (interquartile range) of 130 (117-165) in prior hospitals and 54 (46-84) in subsequent hospitals (the hospital the operator moved to), and the remaining 4 moved from high to high-volume hospitals, with median annual PCI volumes (interquartile range) of 151 (133-162) in prior hospitals and 193 (178-239) in subsequent hospitals. No significant differences were observed in the risk-adjusted mortality ratios and MACE ratios between high-volume operators and matched controls before and after moving. CONCLUSIONS High-volume operators cannot maintain high volume when they moved from high to moderate or low-volume hospitals; however, the quality of care is maintained. High PCI volume and high-quality outcomes are less portable and more hospital bound.

Regional and hospital variations in the extent of decline in the proportion of percutaneous coronary interventions performed for nonacute indications - a nationwide population-based study. BMC Cardiovasc Disord 2017; 17:149. [PMID: 28599642 PMCID: PMC5466717 DOI: 10.1186/s12872-017-0592-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2017] [Accepted: 06/05/2017] [Indexed: 11/26/2022] Open
Abstract
Background The volume and percentage of percutaneous coronary interventions (PCIs) performed for nonacute indications have declined in the United States since 2007. However, little is known if similar trends occurred in Taiwan. Methods We used data from Taiwan National Health Insurance inpatient claims to examine the regional and hospital variations in the extent of decline in the percentage of nonacute indication PCIs from 2007 to 2012. Results The volume of total PCIs persistently increased from 29,032 in 2007 to 35,811 in 2010 and 37,426 in 2012. However, the volume of nonacute indication PCIs first increased from 7916 in 2007 to 9143 in 2009 and then decreased to 8666 in 2012. The percentage of nonacute indication PCIs steadily decreased from 27% in 2007 to 26% in 2009 and then to 23% in 2012, a − 15% change. The extent of decline was largest in the North region (from 27% to 21%, a − 22% change) and least in Kaopin region (from 20% to 18%, a − 13% change). Of the 71 hospitals studied, 14 did not show a decreasing trend. Five of the 14 hospitals even showed an increasing trend, with a percentage change >10% between 2007 and 2012. In 2012, 6 hospitals had a nonacute indication PCI percentage >35%. Conclusions In Taiwan, four-fifths of the hospitals showed a decline in the percentage of nonacute indication PCIs from 2007 to 2012. It is plausible that Taiwanese cardiologists would have been influenced by the recommendations of crucial US trials and guidelines.

Association of maternal chronic disease with risk of congenital heart disease in offspring. CMAJ 2016; 188:E438-E446. [PMID: 27729382 DOI: 10.1503/cmaj.160061] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/02/2016] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Information about known risk factors for congenital heart disease is scarce. In this population-based study, we aimed to investigate the relation between maternal chronic disease and congenital heart disease in offspring. METHODS The study cohort consisted of 1 387 650 live births from 2004 to 2010. We identified chronic disease in mothers and mild and severe forms of congenital heart disease in their offspring from Taiwan's National Health Insurance medical claims. We used multivariable logistic regression analysis to assess the associations of all cases and specific types of congenital heart disease with various maternal chronic diseases. RESULTS For mothers with the following chronic diseases, the overall prevalence of congenital heart disease in their children was significantly higher than for mothers without these diseases: diabetes mellitus type 1 (adjusted odds ratio [OR] 2.32, 95% confidence interval [CI] 1.66-3.25), diabetes mellitus type 2 (adjusted OR 2.85, 95% CI 2.60-3.12), hypertension (adjusted OR 1.87, 95% CI 1.69-2.07), congenital heart defects (adjusted OR 3.05, 95% CI 2.45-3.80), anemia (adjusted OR 1.31, 95% CI 1.25-1.38), connective tissue disorders (adjusted OR 1.39, 95% CI 1.19-1.62), epilepsy (adjusted OR 1.37, 95% CI 1.08-1.74) and mood disorders (adjusted OR 1.25, 95% CI 1.11-1.41). The same pattern held for mild forms of congenital heart disease. A higher prevalence of severe congenital heart disease was seen only among offspring of mothers with congenital heart defects or type 2 diabetes. INTERPRETATION The children of women with several kinds of chronic disease appear to be at risk for congenital heart disease. Preconception counselling and optimum treatment of pregnant women with chronic disease would seem prudent.

Risks of all-cause and site-specific fractures among hospitalized patients with COPD. Medicine (Baltimore) 2016; 95:e5070. [PMID: 27749576 PMCID: PMC5059079 DOI: 10.1097/md.0000000000005070] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2016] [Revised: 08/18/2016] [Accepted: 09/10/2016] [Indexed: 01/04/2023] Open
Abstract
Patients with chronic obstructive pulmonary disease (COPD) have a high prevalence of osteoporosis. The clinical sequel of osteoporosis is fracture. Patients with COPD who experience a fracture also have increased morbidity and mortality. Currently, the types of all-cause and site-specific fracture among patients with COPD are unknown. Thus, we elucidated the all-cause and site-specific fractures among patients with COPD.A retrospective, population-based, cohort study was conducted utilizing the Taiwan Longitudinal Health Insurance Database.Patients with COPD were defined as those who were hospitalized with an International Classification of Diseases, Ninth Revision, Clinical Modification code of 490 to 492 or 496 between 2001 and 2011. The index date was set as the date of discharge. The study patients were followed from the index date to the date when they sought care for any type of fracture, date of death, date of health insurance policy termination, or the last day of 2013. The types of fracture analyzed in this study included vertebral, rib, humeral, radial and ulnar/wrist, pelvic, femoral, and tibial and fibular fractures.The cohort consisted of 11,312 patients with COPD. Among these patients, 1944 experienced fractures. The most common site-specific fractures were vertebral, femoral, rib, and forearm fractures (radius, ulna, and wrist) at 32.4%, 31%, 12%, and 11.8%, respectively. The adjusted hazard ratios of fracture were 1.71 [95% confidence interval (95% CI) = 1.56-1.87] for female patient with COPD and 1.50 (95% CI = 1.39-1.52) for patients with osteoporosis after covariate adjustment.Vertebral and hip fractures are common among patients with COPD, especially among males with COPD. Many comorbidities contribute to the high risk of fracture among patients with COPD.

Underreporting of maternal mortality in Taiwan: A data linkage study. Taiwan J Obstet Gynecol 2016; 54:705-8. [PMID: 26700989 DOI: 10.1016/j.tjog.2015.10.002] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/31/2014] [Indexed: 10/22/2022] Open
Abstract
OBJECTIVE This study examined the extent to which maternal mortality in Taiwan is underreported in officially published mortality statistics. MATERIALS AND METHODS We used National Health Insurance claims data collected from two million samples, which were linked with the officially published mortality data, to identify women aged 15-49 years, who were admitted to a hospital with pregnancy-related diagnoses during 2000-2009 and died during the pregnancy or within 42 days after the termination of pregnancy. RESULTS Based on these linked data, we identified 26 maternal deaths, only nine of which were reported in the original officially published mortality data; thus, the rate of underreporting was 65% [(26 - 9)/26]. The revised maternal mortality ratio was 14.1 deaths per 100,000 live births (95% confidence interval: 8.7-19.5), which was approximately three times higher than the official reported ratio of 4.9 (95% confidence interval: 1.7-8.1). The most common cause of maternal deaths was amniotic fluid embolism (n = 10), followed by eclampsia and preeclampsia (n = 4). CONCLUSION Approximately two-thirds of the maternal deaths in Taiwan were unreported in the officially published mortality data. Hence, routine nationwide data linkage is essential to monitor maternal mortality in Taiwan accurately.

Cognitively-Related Basic Activities of Daily Living Impairment Greatly Increases the Risk of Death in Alzheimers Disease. PLoS One 2016; 11:e0160671. [PMID: 27571265 PMCID: PMC5003345 DOI: 10.1371/journal.pone.0160671] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2016] [Accepted: 07/22/2016] [Indexed: 11/23/2022] Open
Abstract
INTRODUCTION Some Alzheimer's disease (AD) patients die without ever developing cognitively impaired basic activities of daily living (basic ADL), which may reflect slower disease progression or better compensatory mechanisms. Although impaired basic ADL is related to disease severity, it may exert an independent risk for death. This study examined the association between impaired basic ADL and survival of AD patients, and proposed a multistate approach for modeling the time to death for patients who demonstrate different patterns of progression of AD that do or do not include basic ADL impairment. METHODS 1029 patients with probable AD at the Baylor College of Medicine Alzheimer's Disease and Memory Disorders Center met the criteria for this study. Two complementary definitions were used to define development of basic ADL impairment using the Physical Self-Maintenance Scale score. A weighted Cox regression model, including a time-dependent covariate (development of basic ADL impairment), and a multistate survival model were applied to examine the effect of basic ADL impairment on survival. RESULTS As expected decreased ability to perform basic ADL at baseline, age at initial visit, years of education, and sex were all associated with significantly higher mortality risk. In those unimpaired at baseline, the development of basic ADL impairment was also associated with a much greater risk of death (hazard ratios 1.77-4.06) over and above the risk conferred by loss of MMSE points. A multi-state Cox model, controlling for those other variables quantified the substantive increase in hazard ratios for death conferred by the development of basic ADL impairment by two definitions and can be applied to calculate the short term risk of mortality in individual patients. CONCLUSIONS The current study demonstrates that the presence of basic ADL impairment or the development of such impairments are important predictors of death in AD patients, regardless of severity.

International Ranking of Infant Mortality Rates: Taiwan Compared with European Countries. Pediatr Neonatol 2016; 57:326-32. [PMID: 26768510 DOI: 10.1016/j.pedneo.2015.07.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2015] [Revised: 04/28/2015] [Accepted: 07/14/2015] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Rankings of infant mortality rates are commonly cited international comparisons to assess the health status of individual countries. We compared the infant mortality rate of Taiwan with those of European countries for 2004 according to two definitions. METHODS First, the countries were ranked on the basis of crude infant, neonatal, and postneonatal mortality rates. The countries were then ranked according to the mortality rates calculated after exclusion of live births with a known birth weight of <1000 g, which is the definition set by the World Health Organization. RESULTS Taiwan was ranked 11(th), 12(th), and 15(th) among 26 high-income countries for crude infant, neonatal, and postneonatal mortality rates, respectively. The ranks were 12(th), 16(th), and 15(th), respectively, for mortality rates, excluding live births with a birth weight of <1000 g. However, in only seven, four, and 10 countries were the mortality rate ratios statistically significantly lower than Taiwan in infant, neonatal, and postneonatal mortality, respectively, according to the second definition. CONCLUSION The ranking of Taiwan was similar (11(th) vs. 12(th)) according the two definitions. However, after consideration of the confidence interval, only six countries (Sweden, Finland, Czech Republic, Belgium, Austria, and Germany) had infant mortality rates statistically significantly lower than those of Taiwan in 2004.

Increased risk of new-onset depression in patients with traumatic brain injury and hyperlipidemia: the important role of statin medications. J Clin Psychiatry 2016; 77:505-11. [PMID: 27035519 DOI: 10.4088/jcp.14m09749] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2014] [Accepted: 03/26/2015] [Indexed: 10/22/2022]
Abstract
OBJECTIVE Depression is a common complication after traumatic brain injury (TBI). This study aimed to evaluate the risk of hyperlipidemia for new-onset depression after TBI and the role of statin medications using a longitudinal population database. METHOD A matched longitudinal cohort study of 3,792 subjects (1,264 TBI patients [ICD-9-CM code: 801-804 and 850-854] with preexisting hyperlipidemia [ICD-9-CM code: 272.0, 272.1, 272.2, 272.4] and 2,528 age- and sex-matched TBI patients without hyperlipidemia) was conducted using the Taiwan Longitudinal Health Insurance Database from January 2001 to December 2008. The incidence and hazard ratios (HRs) for the development of new-onset depression (ICD-9-CM code: 296.2X-296.3X, 300.4, and 311.X) after TBI were compared between the 2 groups. RESULTS The incidence rate of depression in TBI with preexisting hyperlipidemia was 136.61 per 10,000 person-years. TBI patients with preexisting hyperlipidemia had a 1.72-fold increased incidence rate ratio compared with those without hyperlipidemia (P = .0056). A Cox model showed hyperlipidemia to be an independent predictor of depression (HR = 1.61; 95% CI, 1.03-2.53). TBI patients with hyperlipidemia who were not treated with statins experienced a 1.95-fold incidence risk ratio (P = .0017) and higher risk of new-onset depression (HR = 1.61; 95% CI, 1.03-2.53) compared to TBI patients without hyperlipidemia. CONCLUSIONS Preexisting hyperlipidemia could be an independent predictor of new-onset depression in TBI patients, and TBI patients with preexisting hyperlipidemia who were not treated with statins presented a higher risk of new-onset depression than TBI patients without hyperlipidemia. Our findings may provide some insight into the important role of statin medications in the development of new-onset depression in patients with traumatic brain injury.
