Abstract
Early identification of Alzheimer's disease (AD) and AD-related dementias (ADRD) has high clinical significance, both because of the potential to slow decline through initiating FDA-approved therapies and managing modifiable risk factors, and to help persons living with dementia and their families to plan before cognitive loss makes doing so challenging. However, substantial racial and ethnic disparities in early diagnosis currently lead to additional inequities in care, urging accurate and inclusive risk assessment programs. In this study, we trained an artificial intelligence foundation model to represent the electronic health records (EHR) data with a vast cohort of 1.2 million patients within a large health system. Building upon this foundation EHR model, we developed a predictive Transformer model, named TRADE, capable of identifying risks for AD/ADRD and mild cognitive impairment (MCI), by analyzing the past sequential visit records. Amongst individuals 65 and older, our model was able to generate risk predictions for various future timeframes. On the held-out validation set, our model achieved an area under the receiver operating characteristic (AUROC) of 0.772 (95% CI: 0.770, 0.773) for identifying the AD/ADRD/MCI risks in 1 year, and AUROC of 0.735 (95% CI: 0.734, 0.736) in 5 years. The positive predictive values (PPV) in 5 years among individuals with top 1% and 5% highest estimated risks were 39.2% and 27.8%, respectively. These results demonstrate significant improvements upon the current EHR-based AD/ADRD/MCI risk assessment models, paving the way for better prognosis and management of AD/ADRD/MCI at scale.

Exploring the Link between Chronic Kidney Disease and Alzheimer's Disease: A Longitudinal Follow-Up Study Using the Korean National Health Screening Cohort. Biomedicines 2023; 11:1606. [PMID: 37371701 DOI: 10.3390/biomedicines11061606] [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: 05/12/2023] [Revised: 05/29/2023] [Accepted: 05/30/2023] [Indexed: 06/29/2023] Open
Abstract
Chronic kidney disease (CKD) and Alzheimer's disease (AD) are common chronic diseases in the elderly population. Although a relationship between CKD and the occurrence of AD has been proposed, previous research results have been disputed, and further investigation is necessary to confirm this relationship. In this longitudinal follow-up study, we examined data from the Korean National Health Insurance Service-Health Screening Cohort, consisting of 15,756 individuals with CKD and 63,024 matched controls aged ≥40 years who received health check-ups between 2002 and 2019. Overlap-weighted Cox proportional hazard regression models were exploited to calculate hazard ratios (HRs) for the association between CKD and AD. During the monitoring period, individuals with CKD had a greater incidence of AD than those without CKD (15.80 versus 12.40 per 1000 person years). After accounting for various factors, CKD was significantly associated with a 1.14-fold increased likelihood of developing AD, with a 95% confidence interval ranging from 1.08 to 1.20. In subgroup analysis, this relationship persisted irrespective of age (≥70 or <70), sex, income, smoking status, alcohol consumption, place of residence, or fasting blood glucose level. Additionally, the association between CKD and AD was still evident among patients who were overweight or obese, those with normal blood pressure or cholesterol levels, and those without any other health conditions or with a CCI score of ≥2. These results suggest that CKD could increase the probability of developing AD in the Korean adult population irrespective of demographic or lifestyle conditions. This may make it challenging to predict AD in patients with CKD, emphasizing the importance of frequent AD screening and management.

Predicting cognitive impairment in chronic kidney disease patients using structural and functional brain network: An application study of artificial intelligence. Prog Neuropsychopharmacol Biol Psychiatry 2023; 122:110677. [PMID: 36395980 DOI: 10.1016/j.pnpbp.2022.110677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 08/20/2022] [Accepted: 11/10/2022] [Indexed: 11/16/2022]
Abstract
OBJECTIVE To develop and validate artificial intelligence models for the prediction of cognitive impairment in chronic kidney disease (CKD) patients using structural and functional brain network. METHODS This study retrospectively recruited 621 CKD patients and 625 healthy controls in Jinling hospital and 57 CKD patients in Hainan hospital. These CKD patients were divided into cognitive function impairment (CFI) group and non-CFI group based on diagnostic criteria. All patients underwent brain MRI scan, neuropsychological test and laboratory exam. A deep learning model (Attention MLP) based on structural and functional sub-network (determined by the comparison between the patients and healthy controls) topological properties was developed to generate the MRI signature for the discrimination of CFI. Finally, a clinical-topological logistic regression model was built by combining MRI signature and clinical features. The area under curve (AUC), sensitivity and specificity were calculated to evaluate the model performance. Delong test was used to examine the difference of AUCs between models. The integrated discrimination improvement (IDI) and net reclassification index (NRI) between models were calculated. RESULTS Attention MLP model performed well in both internal test set and external test set (AUC = 0.744 and 0.763, respectively). After combining with the clinical features, the model performance was further improved both in the internal (AUC: 0.748) and external test sets (AUC: 0.774), while both IDI and NRI were significant (all p < 0.05) in the external test set. According to the comprehensive comparison, the AUC of the Attention MLP model was significantly or marginal significantly higher than that of traditional machine learning models (logistic regression: AUC = 0.634; support vector machine: AUC = 0.613; decision tree: AUC = 0.539; XGBoost: AUC = 0.639) in internal test set. The results showed that the model built on the combining of structural and functional networks data outperformed those on the single network, as well as the connection matrix. CONCLUSION The result indicated that the integration of the clinical information and the MRI signature generated by artificial intelligence model based on structural and functional network topological properties could help to predict the CFI of CKD patients effectively. Our results provided a set of quantifiable imaging biomarkers for CFI which may be beneficial to CKD patients.

Abstract
INTRODUCTION The relationship between impaired kidney function (KF), dementia, and brain pathologies remains unclear. METHODS A total of 1354 dementia- and kidney disease-free participants including 895 with normal and 459 with impaired KF were followed from 2002 until 2020 (median [interquartile range]: 5 [2-9]) to detect incident dementia. KF was assessed at baseline and categorized as normal or impaired. Over the follow-up, 453 participants died and underwent autopsies for neuropathological assessment. RESULTS Compared to those with normal KF, the hazard ratios (95% confidence intervals [CIs]) of those with impaired KF was 1.48 (1.15, 1.90)/1.44 (1.10, 1.88) for dementia/Alzheimer's dementia. Furthermore, impaired KF was related to a significantly higher burden of cerebral amyloid angiopathy (CAA; odds ratio = 1.96, 95% CI: 1.17, 3.30), but not to other brain pathologies. DISCUSSION Impaired KF is associated with an increased risk of dementia and Alzheimer's dementia. CAA may underlie, in part, this association. HIGHLIGHTS Impaired kidney function (KF) was associated with higher dementia and Alzheimer's dementia risk. Impaired KF anticipated dementia and Alzheimer's dementia onset by more than 1.5 years. Impaired KF was significantly related to a higher burden of cerebral amyloid angiopathy (CAA) but not to other brain pathologies.

[PMID: 36374833 DOI: 10.1016/j.arr.2022.101762] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 10/07/2022] [Accepted: 10/14/2022] [Indexed: 01/31/2023]
Abstract
OBJECTIVE This study aimed to evaluate the bidirectional association between the kidney dysfunction and the brain health, including structural and functional abnormalities. DESIGN Systematic review and meta-analysis with network meta-analysis for outcomes with different estimated glomerular filtration rate (eGFR) ranges. DATA SOURCES PubMed, Embase database, Cochrane library and Web of Science (up to Dec. 2021). ELIGIBILITY CRITERIA FOR SELECTING STUDIES Longitudinal studies that provided evidence of the impact of kidney function estimated from eGFR and urine albumin-to-creatinine ratio (UACR) or chronic kidney disease (CKD) on structural and functional brain abnormalities, and those that provided evidence of the opposite relationship. Studies with study population mean age under 18 years old were excluded. MAIN OUTCOME MEASURES Two independent reviewers screened the included studies, extracted the data, and assessed the risk of bias. We performed a random-effects meta-analysis and a network meta-analysis for outcomes with compatible data. We assessed the risk of bias using the Newcastle-Ottawa Quality Assessment Scale criteria (NOS). Subgroup and sensitivity analyses were conducted to explore heterogeneity in the meta-analyses. Inconsistency analyses using the node-splitting method were performed to confirm the results of network meta-analysis. RESULTS A total of 53 studies with 3037,357 participants were included in the current systematic review. Among these, 16 provided evidence of structural brain abnormalities, and 38 provided evidence of cognitive impairment and dementia. Analysis of evidence of categorical kidney function showed a positive association between kidney dysfunction and cerebral small vessel disease (cSVD) (relative risk (RR) 1.77, 95% confidence interval (CI) 1.40-2.24, I2 = 0.0%), but such results were not found in the analyses of evidence where the kidney function was measured as a continuous variable. Meanwhile, analysis of 28 prior longitudinal studies with 194 compatible sets of data showed that the worse kidney function as categorical variables was related to a greater risk of global brain cognitive disorder (RR 1.28, 95% CI 1.20-1.36, I2 = 82.5%). CONCLUSIONS In this systematic review and meta-analysis, we found a positive association between CKD and functional brain disorders. However, the relationship between the kidney dysfunction and structural abnormalities in the brain remains controversial. As for the opposite relationship, structural brain abnormalities, especially cerebral microbleeds and silent infarction, but not functional brain abnormalities, are associated with worse renal function. In addition, a higher UACR, but not a lower eGFR, was associated with a higher risk of Alzheimer's disease and vascular dementia.

Abstract
INTRODUCTION Decreased renal function is a potential risk factor for dementia. METHODS This retrospective cohort study of 2.8 million adults aged ≥50 years used the IMRD-THIN database, representative of UK primary care, from January 1, 1995 to February 24, 2020. The associations between estimated glomerular filtration rate (eGFR) and urine albumin creatinine ratio (ACR) with incident all-cause dementia were analyzed using Cox regression. RESULTS In the eGFR cohort (n = 2,797,384), worsening renal dysfunction was associated with increased hazard of all-cause dementia, with greatest hazard at eGFR 15-30 ml/min/1.73min2 (hazard ratio [HR] 1.26, 95% confidence interval [CI] 1.19-1.33). In the ACR cohort (n = 641,912), the hazard of dementia increased from ACR 3-30 mg/mmol (HR 1.13, 95% CI 1.10-1.15) to ACR > 30 mg/mmol (HR 1.25, 95% CI 1.18-1.33). DISCUSSION Worsening eGFR and albuminuria have graded associations with the risk of dementia, which may have significant implications for the care of patients with kidney disease.

Abstract
Alzheimer's disease (AD) is a progressive neurodegenerative disorder that is the most common cause of dementia. Over a third of dementia cases are estimated to be due to potentially modifiable risk factors, thus offering opportunities for both identification of those most likely to be in early disease as well as secondary prevention. Diabetes, hypertension and chronic kidney failure have all been linked to increased risk for AD and dementia and through their high prevalence are particularly apt targets for initiatives to reduce burden of AD. This can take place through targeted interventions of cardiovascular risk factors (shown to improve cognitive outcomes) or novel disease modifying treatments in people with confirmed AD pathology. The success of this approach to secondary prevention depends on the availability of inexpensive and scalable methods for detecting preclinical and prodromal dementia states. Developments in blood-based biomarkers for Alzheimer's disease are rapidly becoming a viable such method for monitoring large at-risk groups. In addition, digital technologies for remote monitoring of cognitive and behavioral changes can add clinically relevant data to further improve personalisation of prevention strategies. This review sets the scene for this approach to secondary care of dementia through a review of the evidence for cardiovascular risk factors (diabetes, hypertension and chronic kidney disease) as major risk factors for AD. We then summarize the developments in blood-based and cognitive biomarkers that allow the detection of pathological states at the earliest possible stage. We propose that at-risk cohorts should be created based on the interaction between cardiovascular and constitutional risk factors. These cohorts can then be monitored effectively using a combination of blood-based biomarkers and digital technologies. We argue that this strategy allows for both risk factor reduction-based prevention programmes as well as for optimisation of any benefits offered by current and future disease modifying treatment through rapid identification of individuals most likely to benefit from them.

Abstract
OBJECTIVES It is unclear whether kidney disease is a risk factor for developing dementia. We examined the association between kidney disease and risk of future dementia. DESIGN AND SETTING Nationwide historical registry-based cohort study in Denmark based on data from 1 January 1995 until 31 December 2016. PARTICIPANTS All patients diagnosed with kidney disease and matched general population cohort without kidney disease (matched 1:5 on age, sex and year of kidney disease diagnosis). PRIMARY AND SECONDARY OUTCOME MEASURES All-cause dementia and its subtypes: Alzheimer's disease, vascular dementia and other specified or unspecified dementia. We computed 5-year cumulative incidences (risk) and hazard ratios (HRs) for outcomes using Cox regression analyses. RESULTS The study cohort comprised 82 690 patients with kidney disease and 413 405 individuals from the general population. Five-year and ten-year mortality rates were twice as high in patients with kidney disease compared with the general population. The 5-year risk for all-cause dementia was 2.90% (95% confidence interval: 2.78% to 3.08%) in patients with kidney disease and 2.98% (2.92% to 3.04%) in the general population. Compared with the general population, the adjusted HRs for all-cause dementia in patients with kidney disease were 1.06 (1.00 to 1.12) for the 5-year follow-up and 1.08 (1.03 to 1.12) for the entire study period. Risk estimates for dementia subtypes differed substantially and were lower for Alzheimer's disease and higher for vascular dementia. CONCLUSIONS Patients diagnosed with kidney disease have a modestly increased rate of dementia, mainly driven by vascular dementia. Moreover, patients with kidney disease may be underdiagnosed with dementia due to high mortality and other comorbidities of higher priority.

Abstract
Chronic (neuro)inflammation plays an important role in many age-related central nervous system (CNS) diseases, including Alzheimer's disease, Parkinson's disease and vascular dementia. Inflammation also characterizes many conditions that form a risk factor for these CNS disorders, such as physical inactivity, obesity and cardiovascular disease. Lipocalin 2 (Lcn2) is an inflammatory protein shown to be involved in different age-related CNS diseases, as well as risk factor conditions thereof. Lcn2 expression is increased in the periphery and the brain in different age-related CNS diseases and also their risk factor conditions. Experimental studies indicate that Lcn2 contributes to various neuropathophysiological processes of age-related CNS diseases, including exacerbated neuroinflammation, cell death and iron dysregulation, which may negatively impact cognitive function. We hypothesize that increased Lcn2 levels as a result of age-related risk factor conditions may sensitize the brain and increase the risk to develop age-related CNS diseases. In this review we first provide a comprehensive overview of the known functions of Lcn2, and its effects in the CNS. Subsequently, this review explores Lcn2 as a potential (neuro)inflammatory link between different risk factor conditions and the development of age-related CNS disorders. Altogether, evidence convincingly indicates Lcn2 as a key constituent in ageing and age-related brain diseases.

Abstract
BACKGROUND The objective of the study is to investigate the incidence and risk factors of delirium after percutaneous coronary intervention (PCI) in acute coronary syndrome (ACS) patients accompanied with renal dysfunction. MATERIALS AND METHODS This was a prospective and cohort study, performed in a medical center from July 2014 to June 2017, which enrolled ACS patients accompanied with renal dysfunction who were treated with PCI. Univariate analysis and binary logistic regression analysis was used to determine the incidence and risk factors of delirium. RESULTS Data were analyzed from 119 patients. The 7-day incidence of delirium after PCI in ACS patients accompanied with renal dysfunction was 15.97% (n = 19/119). The binary logistic regression analysis results indicate that age (odd ratio [OR] 1.463; 95% confidence interval [CI] 1.070-2.001; P = 0.017), preoperative higher serum cortisol (COR) (OR 1.025; 95% CI 1.002-1.048; P = 0.030), and lower serum acetylcholine (Ach) (OR 0.965; 95% CI 0.937-0.993; P = 0.016) were significant differences in delirium and nondelirium groups. CONCLUSIONS Age, preoperative higher serum COR levels, and lower serum Ach levels were independent risk factors for delirium after PCI in ACS patients accompanied with renal dysfunction.

Abstract
This study aimed to assess the association between chronic kidney disease (CKD) and the risk of pulmonary tuberculosis (TB) before initiating renal replacement therapy (RRT) in Taiwan.Total 16,052 subjects newly diagnosed with CKD between 2000 and 2012 were included in the CKD group, and 31,949 randomly selected subjects who did not have CKD formed the non-CKD group. Subjects with a history of pulmonary TB or RRT, including dialysis and renal transplantation, before the index date were excluded. We determined the incidence of pulmonary TB at the end of 2013. A multivariable Cox proportional hazards regression model was used to assess the hazard ratio (HR) and 95% confidence interval (CI) for the risk of developing pulmonary TB associated with CKD.The overall incidence of pulmonary TB was 1.47-fold greater in the CKD group compared to that in the non-CKD group (4.94 vs 3.35 per 1000 person-years, 95% CI 1.39, 1.56). Multivariable Cox proportional hazards regression analysis showed that the adjusted HR of pulmonary TB was 1.45-fold higher in the CKD group (95% CI 1.27, 1.64) than in the non-CKD group. Male sex (adjusted HR 2.04), age (increase per one year, adjusted HR 1.05), chronic obstructive pulmonary disease (adjusted HR 1.54), and diabetes mellitus (adjusted HR 1.34) were also associated with pulmonary TB.CKD is associated with an increased risk of developing pulmonary TB before the initiation of RRT.

Abstract
BACKGROUND Benzodiazepine use is highly prevalent in elderly and late middle-aged populations and may be associated with an increased risk of dementia. Observational studies have suggested that benzodiazepine use may increase the risk of dementia, however there have been significant concerns regarding protopathic bias in these studies, precluding conclusive findings. OBJECTIVE The aim of our study was to investigate the risk of dementia associated with the use of benzodiazepines in elderly patients, after controlling for protopathic bias. METHODS We identified observational studies with more than 50 cases, adequate assessment of benzodiazepine exposure, and reliable dementia diagnosis ascertainment, from the MEDLINE, PubMed, EMBASE, CINAHL, LILACS and CENTRAL electronic databases through to 5 June 2018, with no language limits. The association of any current or former use of short- or long-acting benzodiazepines with incident dementia was analysed. A subgroup analysis was performed by the introduction of lag time to assess the effect of protopathic bias. We also performed analyses considering the effect of higher benzodiazepine cumulative doses and adjustment for psychiatric covariates. Study quality was investigated using the Newcastle-Ottawa Scale. RESULTS We identified 15 studies reported in 14 articles, involving 159,090 cases. Ever use of benzodiazepines was associated with a significantly increased risk of dementia [odds ratio (OR) 1.39, 95% confidence interval (CI) 1.21-1.59]. Those studies that implemented the longest lag times of ≥ 5 years, and hence most likely to overcome protopathic bias, found a risk estimate that was marginally attenuated, but still significant (OR 1.30, 95% CI 1.14-1.48). Long-acting benzodiazepines were associated with a marginally higher magnitude risk (OR 1.21, 95% CI 0.99-1.49) than short-acting benzodiazepines (OR 1.13, 95% CI 1.02-1.26), although the former failed to reach statistical significance (p = 0.059). CONCLUSIONS Our findings indicate that the association between benzodiazepine use and dementia incidence is not purely an artefact due to protopathic bias. Reduction of inappropriate benzodiazepine prescription is likely to attenuate dementia risk.

Abstract
OBJECTIVE Dietary magnesium may be associated with a lower risk of dementia; however, the impact of magnesium oxide (MgO), a common laxative, on dementia has yet to be elucidated. This study aimed to investigate the association between the usage of MgO and the risk of developing dementia. METHODS We used a dataset from the National Health Research Institute Database (NHRID) of Taiwan containing one million randomly sampled subjects to identify patients aged ≥50 years with no history of MgO usage. A total of 1547 patients who had used MgO were enrolled, along with 4641 controls who had not used the MgO propensity score matched by age, gender and comorbidity, at a ratio of 1:3. After adjusting for confounding risk factors, a Cox proportional hazards model was used to compare the risk of developing dementia during a 10 year follow-up period. RESULTS Of the enrolled patients, 44 (2.84%) developed dementia, when compared to 199 (4.28%) in the control group. The Cox proportional hazards regression analysis revealed that the patients who had used MgO were less likely to develop dementia with a crude hazard ratio of 0.617 (95% CI, 0.445-0.856, p = .004). After adjusting for age, gender, comorbidity, geographical area and urbanization level of residence, and monthly income, the adjusted hazard ratio was 0.517 (95% CI, 0.412-0.793, p = .001). CONCLUSIONS The patients who used MgO had a decreased risk of developing dementia. Further studies on the effects of MgO in reducing the risk of dementia are therefore warranted.

Abstract
BACKGROUND/OBJECTIVE The incidence of pyogenic liver abscess in Taiwan appears to be much higher than that in western countries. However, little is known about the incidence of pyogenic liver abscess among patients with predialysis chronic kidney disease. The objective of this study was to assess the association between predialysis chronic kidney disease and the risk of pyogenic liver abscess in Taiwan. METHODS This population-based, retrospective, cohort study was conducted to analyse the database of the Taiwan National Health Insurance Program. There were 81118 subjects aged 20-84 years with newly diagnosed chronic kidney disease as the predialysis chronic kidney disease group since 2000-2010, and 81118 randomly selected subjects without chronic kidney disease as the nonchronic kidney disease group. The predialysis chronic kidney disease group and the nonchronic kidney disease group were matched with sex, age and comorbidities. The incidence of pyogenic liver abscess at the end of 2013 was calculated in both groups. Subjects who currently received dialysis therapy before the endpoint were excluded from the study. The multivariable Cox proportional hazards regression model was used to assess the hazard ratio (HR) and 95% confidence interval (CI) for the risk of pyogenic liver abscess associated with predialysis chronic kidney disease and other comorbidities including alcohol-related disease, biliary stone, chronic liver disease and diabetes mellitus. RESULTS The overall incidence of pyogenic liver abscess was 1·65-fold higher in the predialysis chronic kidney disease group than that in the nonchronic kidney disease group (1·38 vs. 0·83 per 1000 person-years, 95% CI 1·59, 1·71). After adjustment for covariables, the adjusted HR of pyogenic liver abscess was 1·51(95% CI 1·30, 1·76) for the predialysis chronic kidney disease group, comparing with the nonchronic kidney disease group. In addition, the adjusted HR would increase to 3·31 (95% CI 2·61, 4·19) for subjects with predialysis chronic kidney disease and with any comorbidity studied. CONCLUSION Predialysis chronic kidney disease is associated with 1·5-fold increased risk of pyogenic liver abscess. There seem to be a synergistic effect on the risk of pyogenic liver abscess between predialysis chronic kidney disease and comorbidities.

Abstract
OBJECTIVES This study aimed to examine the association between fluvastatin use and acute pancreatitis in Taiwan. METHODS Using the database from the Taiwan National Health Insurance (NHI) Program, we designed a case-control study which consisted of 3501 individuals aged 20-84 with new at-the-time diagnoses acute pancreatitis as the case group and 8373 randomly selected individuals without acute pancreatitis as the control group during the period of 1998-2011. Both groups were matched for sex, age, and index year of being diagnosed with acute pancreatitis. "Current use" of fluvastatin was defined as individuals whose last remaining tablet of fluvastatin was noted ≤ 7 days before the date of their being diagnosed with acute pancreatitis. "Late use" of fluvastatin was defined as individuals whose last remaining tablet of fluvastatin was noted within 8-30 days before the date of their being diagnosed with acute pancreatitis. "No use" of fluvastatin was defined as individuals who had never had a fluvastatin prescription. The odds ratio (OR) and 95% confidence interval (CI) for acute pancreatitis associated with fluvastatin use was examined using a multivariable unconditional logistic regression analysis. RESULTS After adjustment for potential confounders, the multivariable analysis showed that the adjusted ORs of acute pancreatitis were 1.17 for individuals with "current use" of fluvastatin (95% CI 0.69, 1.97) and 1.82 for individuals with "late use" of fluvastatin (95% CI 0.41, 8.19), but there was no statistical significance when compared with individuals with "no use" of fluvastatin. CONCLUSIONS In this this study, no association was detected between fluvastatin use and acute pancreatitis.

Abstract
BACKGROUND AND OBJECTIVES Few studies have reported the association of the use of selective serotonin reuptake inhibitors (SSRIs) with acute pancreatitis. We conducted a population-based case-control study to explore this relationship. METHODS In this study, 4631 cases with first attack of acute pancreatitis and 4631 controls without acute pancreatitis were selected using a randomly sampled cohort of one million health insurance enrollees from 2000 to 2013. Both cases and controls were aged 20-84 years and were matched with sex, age, comorbidities, and index year of diagnosis of acute pancreatitis. Patients with current use of SSRIs were defined as those whose last tablet of SSRIs was noted ≤ 7 days before the date of diagnosis of acute pancreatitis; patients with late use of SSRIs were defined as those whose last tablet of SSRIs was noted ≥ 8 days before the date of diagnosis; and patients with no use of SSRIs were defined as those who were never prescribed SSRIs. The odds ratio (OR) and 95% confidence interval (CI) for acute pancreatitis associated with the use of SSRIs were assessed using multivariate unconditional logistic regression analysis. RESULTS After adjusting for covariables, multivariate logistic regression analysis revealed that compared with patients with no use of SSRIs, the adjusted OR of acute pancreatitis for those with current use of SSRIs was 1.7 (95% CI, 1.1-2.5), whereas that for patients with late use of SSRIs was 1.0 (95% CI, 0.9-1.2) without statistical significance. CONCLUSIONS Current use of SSRIs is associated with the diagnosis of acute pancreatitis. Therefore, clinicians should consider the possibility of SSRI-associated acute pancreatitis among patients currently taking SSRIs and those presenting with the diagnosis of acute pancreatitis without a definite cause.

Cognitive impairment and dementia commonly occur in individuals with chronic kidney disease, especially in advanced stages, but are still poorly diagnosed. OBJECTIVE To evaluate the cognitive ability of patients with chronic kidney disease on hemodialysis and its relationship with sociodemographic and clinical characteristics. METHODS A cross-sectional study was carried out in a Renal Replacement Therapy Unit in the interior of the State of São Paulo involving 99 patients. The data were collected through an individual interview, using the Sociodemographic and Clinical Characterization questionnaires and the Addenbrooke's Cognitive Examination - Revised (ACE-R) questionnaire. RESULTS Participants were predominantly male, with a mean age of 54.68 years. The mean ACE-R score was 64.26 points, and 76.76% of patients had lower-than-expected scores, suggesting the presence of cognitive impairment. A moderate, negative correlation was found between total score on the ACE-R and age (r= -0.38, p≤0.001), a moderate positive correlation with years of education (r=0.52, p≤0.001), and a weak positive correlation of total score with hemodialysis time (r=0.26, p≤0.001). CONCLUSION A relationship was found between cognitive ability and age, years of education and hemodialysis time, suggesting that individuals who were older, had less education and longer hemodialysis time presented greater cognitive impairment.

Abstract
BACKGROUND/OBJECTIVE Little is known about the relationship between proton pump inhibitors use and pyogenic liver abscess. The objective of this study was to evaluate the correlation between proton pump inhibitors use and pyogenic liver abscess in Taiwan. METHODS This was a population-based case-control study using the database of the Taiwan National Health Insurance Program since 2000 to 2011. Subjects aged 20 to 84 who experienced their first episode of pyogenic liver abscess were enrolled as the case group (n = 1372). Randomly selected subjects aged 20 to 84 without pyogenic liver abscess were enrolled as the control group (n = 1372). Current use, early use, and late use of proton pump inhibitors was defined as subjects whose last one tablet for proton pump inhibitors was noted ≤30 days, between 31 to 90 days and ≥91 days before the date of admission for pyogenic liver abscess. Subjects who never received a prescription for proton pump inhibitors were defined as nonusers of proton pump inhibitors. A multivariable unconditional logistic regression model was used to measure the odds ratio and 95% confidence interval to evaluate the correlation between proton pump inhibitors use and pyogenic liver abscess. RESULTS After adjusting for confounders, the adjusted odds ratio of pyogenic liver abscess was 7.59 for subjects with current use of proton pump inhibitors (95% confidence interval 5.05, 11.4), when compared with nonusers. CONCLUSIONS Current use of proton pump inhibitors is associated with a greater risk of pyogenic liver abscess.

Abstract
AIM The objective of this review was to assess chronic kidney disease-related frailty and cognitive impairment, as well as their probable causes, mechanisms and the interventions. METHODS Studies from 1990 to 2015 were reviewed to evaluate the relationship between chronic kidney disease and physical frailty and cognitive impairment. Of the 1694 studies from the initial search, longitudinal studies (n = 22) with the keywords "Cognitive and CKD" and longitudinal or cross-sectional studies (n = 5) with the keywords "Frailty and CKD" were included in final analysis. RESULTS By pooling current research, we show clear evidence for a relationship between chronic kidney disease and frailty and cognitive impairment in major studies. Vascular disease is likely an important mediator, particularly for cognitive impairment. However, non-vascular factors also play an important role. Many of the other mechanisms that contribute to impaired cognitive function and increased frailty in CKD remain to be elucidated. In limited studies, medication therapy did not obtain the ideal effect. There are limited data on treatment strategies, but addressing the vascular disease risk factors earlier in life might decrease the subsequent burden of frailty and cognitive impairment in this population. Multidimensional interventions, which address both microvascular health and other factors, may have substantial benefits for both the cognitive impairments and physical frailty in this vulnerable population. CONCLUSIONS Chronic kidney disease is a potential cause of frailty and cognitive impairment. Vascular and non-vascular factors are the possible causes. The mechanism of chronic kidney disease-induced physical frailty and cognitive impairment suggests that multidimensional interventions may be effective therapeutic strategies in the early stage of chronic kidney disease.

Abstract
The correlation between simvastatin use and acute pancreatitis is explored. A case-control study was conducted to analyze claim data from the Taiwan National Health Insurance Program. The case group comprising a total of 3882 subjects aged 20 to 84 years with their first acute pancreatitis episode occurring between 1998 and 2011 formed the case group, against 3790 randomly selected controls matched for sex, age, comorbidities, and index year of acute pancreatitis diagnosis. Recent use of simvastatin was defined as subjects whose last remaining simvastatin tablet was noted ≤7 days before the date of acute pancreatitis diagnosis. Remote use of simvastatin was defined as subjects whose last remaining 1 tablet for simvastatin was noted >7 days before the date of acute pancreatitis diagnosis. Never use of simvastatin was defined as subjects who had never been prescribed simvastatin. A multivariable unconditional logistic regression model was used to estimate the odds ratio and 95%CI to explore the correlation between simvastatin use and acute pancreatitis. After adjustment for confounders, multivariable logistic regression analysis revealed that the adjusted odds ratio of acute pancreatitis was 1.3 for subjects with recent use of simvastatin (95%CI 1.02, 1.73), when compared with those with never use of simvastatin. The crude odds ratio decreased to 1.1 for those with remote use of simvastatin (95%CI 0.93, 1.34) but without statistical significance. Recent use of simvastatin is associated with acute pancreatitis. Clinicians should consider the possibility of simvastatin-associated acute pancreatitis for patients presenting for acute pancreatitis without known cause.

Abstract
Little research focuses on the association between immune thrombocytopenic purpura and human immunodeficiency virus infection in Taiwan. This study investigated whether immune thrombocytopenic purpura might be an early hematologic manifestation of undiagnosed human immunodeficiency virus infection in Taiwan. We conducted a retrospective population-based cohort study using data of individuals enrolled in Taiwan National Health Insurance Program. There were 5472 subjects aged 1-84 years with a new diagnosis of immune thrombocytopenic purpura as the purpura group since 1998-2010 and 21,887 sex-matched and age-matched, randomly selected subjects without immune thrombocytopenic purpura as the non-purpura group. The incidence of human immunodeficiency virus infection at the end of 2011 was measured in both groups. We used the multivariable Cox proportional hazards regression model to measure the hazard ratio and 95 % confidence interval (CI) for the association between immune thrombocytopenic purpura and human immunodeficiency virus infection. The overall incidence of human immunodeficiency virus infection was 6.47-fold higher in the purpura group than that in the non-purpura group (3.78 vs. 0.58 per 10,000 person-years, 95 % CI 5.83-7.18). After controlling for potential confounding factors, the adjusted HR of human immunodeficiency virus infection was 6.3 (95 % CI 2.58-15.4) for the purpura group, as compared with the non-purpura group. We conclude that individuals with immune thrombocytopenic purpura are 6.47-fold more likely to have human immunodeficiency virus infection than those without immune thrombocytopenic purpura. We suggest not all patients, but only those who have risk factors for human immunodeficiency virus infection should receive testing for undiagnosed human immunodeficiency virus infection when they develop immune thrombocytopenic purpura.

Abstract
OBJECTIVE The aim of this study was to explore the association between etodolac use and acute in Taiwan. DESIGN We designed a case-control study using the database of Taiwan's National Health Insurance. SUBJECTS In all, 7577 subjects aged 20 years or older with newly diagnosed acute pancreatitis were defined as cases, and 27032 sex-matched and age-matched subjects without acute pancreatitis were defined as controls. The period considered for this study was from 1998 to 2011. For the study, never having used etodolac is defined as a subject never receiving a prescription for etodolac. Active use of etodolac is defined as a subject receiving at least 1 prescription for etodolac within 7 days of the date of their being diagnosed with acute pancreatitis. Non-active use of etodolac is defined as a subject not receiving a prescription for etodolac within 7 days but receiving at least 1 prescription for etodolac ≥ 8 days before the date of their being diagnosed with acute pancreatitis. MAIN OUTCOME MEASURE The association between etodolac use and acute pancreatitis was estimated by using the multivariable unconditional logistic regression model. RESULTS After correcting for covariates, the adjusted odds ratio of acute pancreatitis was 3.78 for subjects with active use of etodolac (95% confidence interval 1.11, 12.9), compared with subjects who never used etodolac. The adjusted odds ratio decreased to 1.18 for subjects with non-active use of etodolac (95% confidence interval 0.38, 3.67), but that was without statistical significance. CONCLUSION There could be an association between active use of etodolac and acute pancreatitis. Clinicians should take into account the possibility of etodolac-associated acute pancreatitis when patients currently using etodolac present with acute pancreatitis with an unknown cause.

Abstract
Purpose To determine whether acute kidney injury (AKI) is a risk factor for dementia. Methods This nationwide population-based cohort study was based on data from the Taiwan National Health Insurance Research Database for 2000–2011. The incidence and relative risk of dementia were assessed in 207788 patients hospitalized for AKI. The comparison control was selected using the propensity score based on age, sex, index year and comorbidities. Results During the 12-year follow-up, patients with AKI had a significantly higher incidence for developing dementia than did the controls (8.84 vs 5.75 per 1000 person-y). A 1.88-fold increased risk of dementia (95% confidence interval, 1.76–2.01) was observed after adjustment for age, sex, and several comorbidities (diabetes, hypertension, hyperlipidemia, head injury, depression, stroke, chronic obstructive pulmonary disease, coronary artery disease, congestive heart failure, atrial fibrillation, cancer, liver disease, chronic infection/inflammation, autoimmune disease, malnutrition). Conclusions We found that patients with AKI exhibited a significantly increased risk of developing dementia. This study provides evidence on the association between AKI and long-term adverse outcomes. Additional clinical studies investigating the related pathways are warranted.

Abstract
Objective: Adverse neurological effects may be common following acute kidney injury (AKI). The purpose of our study was to investigate the long-term risk of dementia following AKI and temporary dialysis during hospitalization. Materials and Methods: The study was based on data from the National Health Insurance Research Database of Taiwan. Patients 18-year-old and older who were withdrawn from temporary dialysis because of AKI and survived for at least 90 days following discharge were included in our acute-dialysis-recovery group. Patients without AKI and dialysis were the control group. A Cox proportional-hazards regression model was applied to determine the risk of dementia. Results: Of 2905 acute-dialysis patients, 689 (23.7%) survived for at least 90 days following recovery from acute dialysis. The Cox proportional-hazards regression model showed that the acute-dialysis-recovery group had an increased long-term risk of dementia (hazard ratio [HR], 2.01; P = 0.01) compared with the control group. The conditional effects plot showed that the risk of dementia was amplified in patients who were older than 58 years. The development of dementia following recovery from acute dialysis was associated with an increase in all-cause mortality (HR, 2.38; P < 0.001). Conclusions: Patients with acute dialysis have a greater risk for the subsequent development of dementia after recovery than patients without AKI and dialysis, and patients who develop dementia after recovery from temporary dialysis are at increased risk for mortality.

Abstract
Long-term studies demonstrating the effect of pioglitazone use on primary prevention of ischemic cerebrovascular disease in older people with type 2 diabetes mellitus are lacking. This study investigated the relationship between pioglitazone use and first attack of ischemic cerebrovascular disease in Taiwan.We conducted a case-control study using the database of the Taiwan National Health Insurance Program. There were 2359 type 2 diabetic subjects aged ≥65 years with newly diagnosed ischemic cerebrovascular disease from 2005 to 2011 as the case group and 4592 sex- and age-matched, randomly selected type 2 diabetic subjects aged ≥65 years without ischemic cerebrovascular disease as the control group. The odds ratio (OR) with 95% confidence interval (CI) of ischemic cerebrovascular disease associated with pioglitazone use was measured by the multivariable unconditional logistic regression model.After adjustment for confounding factors, the multivariable logistic regression analysis disclosed that the adjusted ORs of first attack of ischemic cerebrovascular disease associated with cumulative duration of using pioglitazone were 3.34 for <1 year (95% CI 2.59-4.31), 2.53 for 1 to 2 years (95% CI 1.56-4.10), 2.20 for 2 to 3 years (95% CI 1.05-4.64), and 1.09 for ≥3 years (95% CI 0.55-2.15), respectively.Our findings suggest that pioglitazone use does not have a protective effect on primary prevention for ischemic cerebrovascular disease among older people with type 2 diabetes mellitus during the first 3 years of use. Whether using pioglitazone for >3 years would have primary prevention for ischemic cerebrovascular disease needs a long-term research to prove.

Abstract
Little is known on the association between appendectomy and pyogenic liver abscess. The objective of this study was to investigate the association between appendectomy and the risk of pyogenic liver abscess in Taiwan.This population-based retrospective cohort study was conducted using the hospitalization dataset of the Taiwan National Health Insurance Program. There were 212,530 subjects age 20 to 84 years with newly diagnosed appendectomy as the appendectomy group since 1998 to 2010, and 850,099 randomly selected subjects without appendectomy as the nonappendectomy group. Both appendectomy and nonappendectomy groups were matched with sex, age, comorbidities, and index year of diagnosing appendectomy. The incidence of pyogenic liver abscess at the end of 2011 was estimated in both groups. The multivariable Cox proportional hazards regression model was applied to investigate the hazard ratio (HR) and 95% confidence interval (CI) for risk of pyogenic liver abscess associated with appendectomy and other comorbidities including alcoholism, biliary stone, chronic kidney disease, chronic liver diseases, and diabetes mellitus.The overall incidence of pyogenic liver abscess was 1.73-fold greater in the appendectomy group than that in the nonappendectomy group (3.85 vs 2.22 per 10,000 person-years, 95% CI 1.71, 1.76). The multivariable regression analysis disclosed that the adjusted HR of pyogenic liver abscess was 1.77 for the appendectomy group (95% CI 1.59, 1.97), when compared with the nonappendectomy group.Appendectomy is associated with increased hazard of pyogenic liver abscess. Further studies remain necessary to confirm our findings.

Abstract
A higher risk of dementia was reported in patients undergoing maintenance hemodialysis (HD) compared to those undergoing peritoneal dialysis (PD). Selection bias and competing risk of death were not considered in previous studies. The aim of this study was to investigate dementia risk in patients undergoing HD and PD by using the Taiwan Longitudinal Health Insurance Database. We enrolled 52,332 incident HD patients and 3292 incident PD patients who were older than 40 years between January 1, 1998 and December 31, 2007. During the study period, 3775 patients were diagnosed with dementia in the HD group (177.5 per 10,000 person-years incidence rate) and 181 patients in the PD group (145.9 per 10,000 person-years incidence rate). The results revealed that the higher hazard ratio of HD compared with PD for dementia disappeared after controlling for demographic characteristics, propensity score, and competing death risk (subdistribution hazard ratio was 1.086; 95% confidence interval, 0.940–1.255). In conclusion, HD did not increase the risk of dementia in dialysis-dependent patients compared to PD.

Abstract
Alzheimer's disease (AD) is the most common neurodegenerative disorder in elderly people, but there are still no curative options. Senile plaques and neurofibrillary tangles are considered hallmarks of AD, but cerebrovascular pathology is also common. In this review, we summarize findings on cardiovascular disease (CVD) and risk factors in the etiology of AD. Firstly, we discuss the association of clinical CVD (such as stroke and heart disease) and AD. Secondly, we summarize the relation between imaging makers of pre-clinical vascular disease and AD. Lastly, we discuss the association of cardiovascular risk factors and AD. We discuss both established cardiovascular risk factors and emerging putative risk factors, which exert their effect partly via CVD.

The impact of acute kidney injury with temporary dialysis on the risk of fracture. J Bone Miner Res 2014; 29:676-84. [PMID: 23929760 DOI: 10.1002/jbmr.2061] [Citation(s) in RCA: 73] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2013] [Revised: 07/22/2013] [Accepted: 07/29/2013] [Indexed: 12/21/2022]
Abstract
Acute kidney injury (AKI) has a negative impact on long-term renal function and prognosis. However, the association between acute renal dysfunction and long-term effects on bone disorders has not yet been characterized. Using a population-based cohort study, we aimed to evaluate associations between AKI and long-term effects on bone fractures. We identified relevant data of all hospitalized patients aged >18 years with histories of dialysis-requiring AKI, with subsequent recovery and discharge, from the claim records of the Taiwan National Health Insurance database between 2000 and 2008. We determined long-term de novo bone fracture and all-cause mortality after patients' index-hospitalization discharge using propensity score-adjusted Cox proportional hazard model. Varying-time models were used to adjust for long-term effects of end-stage renal disease (ESRD) on main outcomes. Among 448 AKI patients who had dialysis and survived 90 days after index-hospitalization discharge without reentering dialysis, 273 were male (60.9%) with a mean age of 61.4 ± 16.6 years. Controls included 1792 hospitalized patients without AKI, dialysis, or bone fracture history. In the AKI recovery group, bone fracture incidence was 320 per 10,000 person-years and hazard ratio (HR) of long-term bone fracture was 1.25 (p = 0.049) compared with the control group, independent of subsequent ESRD status (HR = 1.55; p = 0.01). Both AKI recovery status (HR = 2.31; p < 0.001) and time varying factor of bone fracture (HR = 1.43; p < 0.001) were independent predictors of mortality compared with controls. In conclusion, AKI requiring temporary dialysis independently increases long-term risk of bone fracture, regardless of subsequent progression to ESRD. Long-term bone fractures may negatively impact patient mortality.

Lai SW, Wang IK, Lin CL, Chen HJ, Liao KF. Splenectomy correlates with increased risk of pulmonary tuberculosis: a case-control study in Taiwan. Clin Microbiol Infect 2014; 20:764-7. [PMID: 24372744 DOI: 10.1111/1469-0691.12516] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2013] [Revised: 12/17/2013] [Accepted: 12/17/2013] [Indexed: 11/27/2022]
Abstract
This study investigated whether there was an association between splenectomy and pulmonary tuberculosis. This was a case-control study using the database of the Taiwan National Health Insurance Programme. We identified 18 960 patients (aged 20 years or older) with newly diagnosed pulmonary tuberculosis as the case group and 73 988 participants without pulmonary tuberculosis as the control group from 1998 to 2011. Both groups were matched for sex, age (per 5 years) and index year of pulmonary tuberculosis diagnosis. The risk of pulmonary tuberculosis associated with splenectomy and other co-morbidities was estimated. After controlling for confounders, multivariable logistic regression analysis showed that the odds of pulmonary tuberculosis were 1.91 in patients with splenectomy (95% CI 1.06-3.44), compared with the participants without splenectomy. Chronic obstructive pulmonary diseases (OR 3.07, 95% CI 2.94-3.21), pneumoconiosis (OR 2.20, 95% CI 1.90-2.56), chronic kidney diseases (OR 1.49, 95% CI 1.33-1.67), diabetes mellitus (OR 1.57, 95% CI 1.50-1.64) and chronic liver diseases (OR 1.31, 95% CI 1.25-1.37) were associated with an increased risk of pulmonary tuberculosis. The sub-analysis demonstrated that the odds of pulmonary tuberculosis were 4.81 (95% CI 2.31-10.0) for patients co-morbid with splenectomy and any of the above diseases. Splenectomy is associated with a 1.9-fold increased risk of pulmonary tuberculosis in Taiwan. There is a synergistic effect between splenectomy and other co-morbidities on the risk of pulmonary tuberculosis.

Abstract
UNLABELLED This study described the incidence of hip fractures, associated diseases, and related costs generated in dialysis versus non-dialysis patients. INTRODUCTION Skeletal fractures are a great concern in chronic kidney disease patients and, in particular, hip fractures that enhance the mortality. We aimed to accurately determine the incidence of hip fractures and associated diseases and to calculate the costs generated in dialysis patients. METHODS We obtained data from the 2010 French National Hospital Database. We first extracted the hospital stays related to hip fractures as a primary diagnosis according to the ICD-10 codes and then the hospitalizations for dialysis. We compared the frequency of comorbidities in both populations. RESULTS Among the 88,962 patients who suffered from hip fractures, 362 were on dialysis. The incidence was significantly higher in dialysis patients (x4) compared to non-dialysis patients. Women on dialysis experienced hip fractures at an earlier age than non-dialysis women. Dementia was identified as a major risk factor in the dialysis patients (72 vs. 26%, p < 0.0001). Moreover, diabetes and cardiovascular diseases were comorbidities strongly associated with hip fractures in both gender, but hypertension and malnutrition were observed exclusively in men on dialysis. Mortality rate and length of hospital stay were increased (5 days) in both genders. CONCLUSION The incidence of hip fractures is increased in dialysis patients, affecting a larger percentage of men and women on dialysis than in the non-dialysis population and enhancing the financial burden and mortality. Dementia is a major risk factor for hip fractures in dialysis patients in addition to diabetes and cardiovascular diseases.

Abstract
The prevalence of the cardiorenal metabolic syndrome (CRS) is increasing in parallel with obesity, type 2 diabetes mellitus, Alzheimer's disease, and other forms of dementia. Along with metabolic, inflammatory, and immunological abnormalities, there is maladaptive structural remodeling of the heart, kidney, and brain. The term 'diabetic cognopathy' (DC) may be used when discussing functional and structural changes in the brain of the diabetic patient. DC likely represents an advanced form of these changes in the brain that evolve with increasing duration of the CRS and subsequent clinical diabetes. We posit that DC develops due to a convergence of aging, genetic and lifestyle abnormalities (overnutrition and lack of exercise), which result in multiple injurious metabolic and immunologic toxicities such as dysfunctional immune responses, oxidative stress, inflammation, insulin resistance, and dysglycemia (systemically and in the brain). These converging abnormalities may lead to endothelial blood-brain barrier tight junction/adherens junction (TJ/AJ) complex remodeling and microglia activation, which may result in neurodegeneration, impaired cognition, and dementia. Herein, we describe the brain ultrastructural changes evolving from a normal state to maladaptive remodeling in rodent models of CRS including microglia activation/polarization and attenuation and/or loss of the TJ/AJ complexes, pericytes and astrocytes of the neurovascular unit. Further, we discuss the potential relationship between these structural changes and the development of DC, potential therapeutic strategies, and future directions.
