C-Reactive Protein and Risk of Cardiovascular Events and Mortality in Patients with Various Cardiovascular Disease Locations.

Anti-inflammatory drugs reduce the risk of cardiovascular events in patients with coronary artery disease (CAD), but less is known about the relation between inflammation and outcomes in patients with cerebrovascular disease (CeVD), peripheral artery disease (PAD), and abdominal aortic aneurysm (AAA). This study assessed the association between C-reactive protein (CRP) and clinical outcomes in patients with CAD (n = 4,517), CeVD (n = 2,154), PAD (n = 1,154), and AAA (n = 424) from the prospective Utrecht Cardiovascular Cohort-Second Manifestations of ARTerial disease study. The primary outcome was recurrent cardiovascular disease (CVD), defined as myocardial infarction, ischemic stroke, or cardiovascular death. Secondary outcomes were major adverse limb events and all-cause mortality. Associations between baseline CRP and outcomes were assessed using Cox proportional hazards models adjusted for age, sex, smoking, diabetes mellitus, body mass index, systolic blood pressure, non-high-density lipoprotein cholesterol, and glomerular filtration rate. Results were stratified by CVD location. During a median follow-up of 9.5 years, 1,877 recurrent CVD events, 887 major adverse limb events, and 2,341 deaths were observed. CRP was independently associated with recurrent CVD (hazard ratio [HR] per 1 mg/L 1.08, 95% confidence interval [CI] 1.05 to 1.10), and all secondary outcomes. Compared with the first quintile of CRP, HRs for recurrent CVD were 1.60 (95% CI 1.35 to 1.89) for the last quintile ≤10 mg/L and 1.90 (95% CI 1.58 to 2.29) for the subgroup with CRP >10 mg/L. CRP was associated with recurrent CVD in patients with CAD (HR per 1 mg/L 1.08, 95% CI 1.04 to 1.11), CeVD (HR 1.05, 95% CI 1.01 to 1.10), PAD (HR 1.08, 95% CI 1.03 to 1.13), and AAA (HR 1.08, 95% CI 1.01 to 1.15). The association between CRP and all-cause mortality was stronger for patients with CAD (HR 1.13, 95% CI 1.09 to 1.16) than for patients with other CVD locations (HRs 1.06 to 1.08; p = 0.002). Associations remained consistent beyond 15 years after the CRP measurement. In conclusion, greater CRP is independently associated with an increased risk of recurrent CVD and mortality, irrespective of previous CVD location.

Validation study on definition of cause of death in Japanese claims data.

Identifying the cause of death is important for the study of end-of-life patients using claims data in Japan. However, the validity of how cause of death is identified using claims data remains unknown. Therefore, this study aimed to verify the validity of the method used to identify the cause of death based on Japanese claims data. Our study population included patients who died at two institutions between January 1, 2018 and December 31, 2019. Claims data consisted of medical data and Diagnosis Procedure Combination (DPC) data, and five definitions developed from disease classification in each dataset were compared with death certificates. Nine causes of death, including cancer, were included in the study. The definition with the highest positive predictive values (PPVs) and sensitivities in this study was the combination of "main disease" in both medical and DPC data. For cancer, these definitions had PPVs and sensitivities of > 90%. For heart disease, these definitions had PPVs of > 50% and sensitivities of > 70%. For cerebrovascular disease, these definitions had PPVs of > 80% and sensitivities of> 70%. For other causes of death, PPVs and sensitivities were < 50% for most definitions. Based on these results, we recommend definitions with a combination of "main disease" in both medical and DPC data for cancer and cerebrovascular disease. However, a clear argument cannot be made for other causes of death because of the small sample size. Therefore, the results of this study can be used with confidence for cancer and cerebrovascular disease but should be used with caution for other causes of death.

Trends of Ten Leading Causes of Death in Head and Neck Squamous Cell Carcinoma.

OBJECTIVE: An understanding of the leading causes of death in patients with head and neck squamous cell carcinoma (HNSCC) would be helpful to inform doctors, patients, and healthcare providers on disease management. This study aimed to comprehensively study the leading causes of death in these survivors. METHODS: We investigated the trends of risk factors for major causes of death in patients with HNSCC. Causes of death in HNSCC were obtained from the Surveillance, Epidemiology, and End Results registries. We characterized trends in the 5-year cumulative mortality as well as risk factors associated with the ten leading causes of death. RESULTS: Among 48 297 deaths identified, the ten leading causes were as follows: HNSCC, heart disease, lung cancer, chronic obstructive pulmonary disease (COPD), cerebrovascular disease, pneumonia & influenza, accidents & adverse effects, esophagus cancer, chronic liver diseases, and septicemia. Non-HNSCC deaths surpassed HNSCC deaths 4 years after cancer diagnosis. There was a significant decline in the 5-year cumulative mortality from HNSCC, heart disease, lung cancer, COPD, cerebrovascular disease, and esophagus cancer. The risks of mortality from the ten leading causes varied with patient characteristics. CONCLUSION: Our findings provide a useful picture of mortality patterns in HNSCC survivors, which might help when planning personalized HNSCC care.

Tendência da mortalidade das doenças cardiovasculares, nas capitais brasileiras, no período entre 1990 e 2018 / Trends in mortality from cardiovascular diseases in brazilian capitals between 1990 and 2018

As doenças cardiovasculares (DCV) são a principal causa de morte no Brasil e no mundo. As doenças isquêmicas do coração (DIC) e doenças cerebrovasculares (DCBV) estão entre as dez principais causas de mortes no Brasil. A análise de tendência da mortalidade por DCV permite definir populações prioritárias para intervenções, elaborar e avaliar ações em saúde pública. Nesse sentido, o objetivo do estudo foi analisar a tendência da mortalidade por DIC e DCBV nas 27 capitais brasileiras, no período de 1990 a 2018. Trata-se de um estudo ecológico de série temporal, os dados de óbitos foram obtidos através do Sistema de Informações sobre Mortalidade (SIM). Buscando corrigir problemas na qualidade da informação dos registros de óbito do SIM, realizou-se a correção dos óbitos referentes aos dados com sexo e/ou faixa etária ignorada e aos óbitos registrados com causas "mal definidas". As taxas de mortalidade por DIC e DBCV foram padronizadas pelo método direto, tomando-se como população padrão a população do Brasil no ano de 2010. A análise de tendência da mortalidade por DIC e DCBV para a população total, homens e mulheres foi realizada utilizando o modelo de regressão de Poisson. Os resultados mostraram tendência de redução da mortalidade por DCBV tanto para a população total como para homens e mulheres em todas as capitais brasileiras. Vitória, capital da região Sudeste, apresentou a maior redução da taxa de mortalidade total por DCBV dentre todas as capitais brasileiras, -5,6% ao ano (IC95%: -6,0; -5,1%). No entanto, Macapá, capital da região Norte, teve a menor dentre todas as capitais -1,7% ao ano (IC95%: -2,7; -0,7%). Paras as DIC foi observada tendência de redução da mortalidade tanto para a população total como para homens e mulheres nas capitais das regiões Sul, Sudeste e para a maioria das capitais da região Centro-Oeste. As capitais das regiões Norte e Nordeste apresentaram uma variabilidade na tendência da mortalidade por DIC. Conclui-se que as capitais das regiões Sul e Sudeste apresentaram as maiores reduções da tendência da mortalidade por DIC e DCBV. Os achados desse estudo são importantes para prover informações mais detalhadas buscando auxiliar a gestão local na promoção de políticas de saúde pública, planejamento de estratégias e elaboração de medidas e ações em saúde.

Cardiovascular diseases (CVD) are the leading cause of death in Brazil and worldwide. Ischemic heart diseases (IHD) and cerebrovascular diseases (CBVD) are among Brazil's ten main causes of death. The trend analysis of mortality from CVD allows defining priority populations for interventions, designing and evaluating public health actions. In this sense, the study's objective was to analyze the mortality trend from IHD and CBVD in the 27 Brazilian capitals from 1990 to 2018. This is an ecological time-series study with the Mortality Information System (SIM) data. Seeking to correct the quality of the information in the SIM death records, the correction of deaths referring to data with anonymous sex and age group and deaths recorded with "ill-defined" causes was carried out. IHD and CBVD mortality rates were standardized by the direct method, using the population of Brazil in 2010 as the standard population. Trend analysis of IHD and CBVD mortality for the total population, men and women, was performed using the Poisson regression model. The results showed a reduction in the trend of mortality from CBVD for both the total population and for men and women in all Brazilian capitals. Vitória, the capital of the Southeast region, showed the greatest reduction in the total mortality rate from CVD among all Brazilian capitals, -5.6% per year (95%CI: -6.0; -5.1%). However, Macapá, the capital of the North region, had the lowest among all capitals -1.7% per year (95%CI: -2.7; -0.7%). For IHD, a decrease in the mortality trend was observed both for the total population and for men and women in the capitals of the South and Southeast regions and most capitals of the Center-West region. The capitals of the North and Northeast regions showed variability in the trend of IHD mortality. In conclusion, the capitals of the South and Southeast regions showed the greatest reductions in the mortality trend due to IHD and CBVD. The findings of this study are essential to provide more detailed information to assist local management in promoting public health policies, planning strategies, and designing health measures and actions.

Increased risk of cerebrovascular mortality in head and neck cancer survivors aged ≥ 65 years treated with definitive radiotherapy: a population-based cohort study.

BACKGROUND: To investigate the relationship between radiotherapy (RT) and the risk of cerebrovascular mortality (CVM) in head and neck cancer (HNC) survivors aged ≥ 65 years. METHODS: Patients with HNC survivors aged ≥ 65 years diagnosed between 2000 and 2012 were included from the Surveillance, Epidemiology, and End Results database. Kaplan-Meier analysis, Log-rank tests, and Cox proportional-hazards regression models were performed for statistical analyses. RESULTS: We included 16,923 patients in this study. Of these patients, 7110 (42.0%) patients received surgery alone, 5041 (29.8%) patients underwent RT alone, and 4772 (28.2%) patients were treated with surgery and RT. With a median follow-up time of 87 months, 1005 patients died with cerebrovascular disease. The 10-years CVM were 13.3%, 10.8%, and 11.2% in those treated with RT alone, surgery alone, and surgery plus RT, respectively (P < 0.001). The mean time for CVM was shorter in RT alone compared to surgery alone and surgery plus RT (52 months vs. 56-60 months). After adjusting for covariates, patients receiving RT alone had a significantly higher risk of developing CVM compared to those receiving surgery alone (hazard ratio [HR] 1.703, 95% confidence interval [CI] 1.398-2.075, P < 0.001), while a comparable risk of CVM was found between those treated with surgery alone and surgery plus RT (HR 1.106, 95% CI 0.923-1.325, P = 0.274). Similar trends were found after stratification age at diagnosis, gender, tumor location, and marital status. CONCLUSIONS: Definitive RT but not postoperative RT can increase the risk of CVM among older HNC survivors. Long-term follow-up and regular screening for CVD are required for HNC patients who received definitive RT to decrease the risk of CVM.

Frailty Measurement and Implications for Cerebrovascular Disease Management in a Veteran Based Population.

BACKGROUND: Rapid and objective preoperative assessment of patients undergoing carotid endarterectomy (CEA) remains difficult and variable. The Risk Analysis Index (RAI) is a validated medical record-based assessment of frailty that has been used to predict clinical outcomes for patients undergoing surgical procedures including CEA. We applied RAI to a veteran population following CEA for asymptomatic cerebrovascular disease and examined the factors related to post-operative morbidity and mortality. METHODS: After obtaining IRB approval, Veteran Affairs Surgical Quality Improvement Program data was queried for CEA procedures from 2002 to 2015 for ICD-9 codes indicating asymptomatic patients. RAI was then calculated based on Veteran Affairs Surgical Quality Improvement Program variable medical record extraction. Three groupings of patients were undertaken including non-frail (RAI < 30), frail (RAI 30-34) and very frail (RAI ≥ 35). Chi squared and ANOVA were used to assess cohort differences. Binary logistic regression was used to evaluate predictors of post-operative stroke, myocardial infarction (MI), any complication, and death. RESULTS: Between 2002 and 2015, 37,873 asymptomatic patients underwent CEA. Over 98% (37,266) of the patients were male with an average age of 68.3 ± 8.55 years. The cohorts contained 82.8% (n = 31,362), 12.4% (n = 4,678), and 4.8% (n = 1,833) for the non-frail, frail and very frail groups respectively. Frailty was associated with increased rates of post-operative stroke, MI, any complication, death, and longer hospital length of stay (P< 0.001). Operative time did not significantly differ between the groups. Increasing frailty was associated with having one or more complications (OR 1.69, 95% CI 1.50-1.90 for frail and OR 2.79, 95% CI 2.41-3.24 for very frail, (P< 0.001), post-operative stroke in frail (OR 1.33 95% CI 1.06-1.67) and very frail (OR 1.57 1 95% CI 1.14-2.16) patients, and MI in both frail (OR 1.68, CI 1.17-2.43) and very frail (OR 3.73, CI 2.52-5.51) patients. Frailty was also significantly associated with death with in very frail patients (OR 4.14, 95% CI 3.00-5.71, P< 0.001). CONCLUSION: Increasing frailty as determined by RAI was associated with worse post-operative outcomes in asymptomatic patients undergoing CEA. Higher RAI score cohorts were associated with higher rates of postoperative stroke, MI, complications, and death. We recommend the use of this frailty index as a screening tool to guide risk discussions with asymptomatic patients undergoing CEA.

Malperfusion in Acute Type A Aortic Dissection: Management Strategies.

Over the decades, it has been well established that malperfusion complicates a number of acute type A aortic dissection (ATAAD) patients. Of the many complications that arise from ATAAD is malperfusion, which is the result of true lumen compression secondary to the dissection, and it is one of the most dangerous complications. Left untreated, malperfusion can eventually compromise circulation to the vascular beds of almost all vital organs. Clinicians must consider the diagnosis of malperfusion promptly following a diagnosis of acute aortic dissection. The outcomes post-surgery for patients with ATAAD with concomitant malperfusion remains poor, despite mortality for aortic surgery improving over time. Optimal management for ATAAD with associated malperfusion has yet to be implemented, further research is warranted to improve the detection and management of this potentially fatal pathology. In this review, we explore the literature surrounding the complications of malperfusion in ATAAD and the various symptom presentations, investigations, and management strategies available.

Progressive multifocal leukoencephalopathy and Creutzfeldt-Jakob disease: population-wide incidences, comorbidities, costs of care, and outcomes.

Neurological disorders associated with chronic infections are often progressive as well as challenging to diagnose and manage. Among 4.4 million persons from 2004 to 2019 receiving universal health, progressive multifocal leukoencephalopathy (PML, n = 58) and Creutzfeldt-Jakob disease (CJD, n = 93) cases were identified, revealing stable yearly incidence rates with divergent comorbidities: HIV/AIDS affected 37.8% of PML cases while cerebrovascular disease affected 26.9% of CJD cases. Most CJD cases died within 1 year (73%) although PML cases lived beyond 5 years (34.1%) despite higher initial costs of care. PML and CJD represent important neurological disorders with evolving risk variables and impact on health care.

Allisartan isoproxil reduces mortality of stroke-prone rats and protects against cerebrovascular, cardiac, and aortic damage.

Stroke is a common cause of death and disability. Allisartan isoproxil (ALL) is a new angiotensin II receptor blocker and a new antihypertensive drug discovered and developed in China. In the present study we investigated the therapeutic effects of ALL in stroke-prone renovascular hypertensive rats (RHR-SP) and the underlying mechanisms. The model rats were generated via two-kidney two-clip (2K2C) surgery, which led to 100% of hypertension, 100% of cerebrovascular damage as well as 100% of mortality 1 year after the surgery. Administration of ALL (30 mg · kg-1 · d-1 in diet, for 55 weeks) significantly decreased stroke-related death and prolonged lifespan in RHR-SP, but the survival ALL-treated RHR-SP remained of hypertension and cardiovascular hypertrophy compared with sham-operated normal controls. In addition to cardiac, and aortic protection, ALL treatment for 10 or 12 weeks significantly reduced cerebrovascular damage incidence and scoring, along with a steady reduction of blood pressure (BP) in RHR-SP. Meanwhile, it significantly decreased serum aldosterone and malondialdehyde levels and cerebral NAD(P)H oxidase expressions in RHR-SP. We conducted 24 h continuous BP recording in conscious freely moving RHR-SP, and found that a single intragastric administration of ALL produced a long hypotensive effect lasting for at least 12 h on systolic BP. Taken together, our results in RHR-SP demonstrate that ALL can be used for stroke prevention via BP reduction and organ protection, with the molecular mechanisms related to inhibition of angiotensin-aldosterone system and oxidative stress. This study also provides a valuable scoring for evaluation of cerebrovascular damage and drug efficacy.

Mortality risks among blue- and white-collar workers: A time series study among Japanese men aged 25-64 years from 1980 to 2015.

OBJECTIVE: We aimed to analyse age-standardised mortality trends in Japan among blue- and white-collar male workers aged 25-64 years, by major causes of mortality from 1980 to 2015. METHODS: Five-yearly mortality data were extracted from occupation-specific vital statistics maintained by the Japanese Ministry of Health, Labour and Welfare. A time series study was conducted among employed men aged 25-64 years. Age-standardised mortality trends by occupational category were calculated separately for all cancers, ischaemic heart disease, cerebrovascular disease and suicide. Poisson regression analysis was performed to analyse mortality trends by occupational category for each cause. RESULTS: Mortality rates for all cancers and ischaemic heart disease were higher among white-collar workers than blue-collar workers throughout the 35-year study period. The gap in the mortality rates for all four causes of death among blue- and white-collar workers widened in 2000 after Japan's economic bubble burst in the late 1990s. Simultaneously, suicide mortality rates among white-collar workers increased sharply and have remained higher than among blue-collar workers. CONCLUSIONS: White-collar male workers in Japan have a higher risk of mortality than male blue-collar workers. However, despite substantial differences, significant progress has been made in recent years in reducing mortality across all occupations in Japan.

Elderly Mortality from Cerebrovascular Disease in Alagoas, 2000-2016: Spatial-Temporal Analysis

Abstract Background Cerebrovascular diseases (CVDs) are the second leading cause of death in Brazil. Objective This study aimed to describe the epidemiological profile and to analyze the spatiotemporal dynamics of mortality from cerebrovascular disease in the elderly in Alagoas from 2000-2016. Methods This is a multilevel ecological study of all deaths from CVD in individuals aged 60 years or older. Data were collected from the Mortality Information System. The variables were submitted to descriptive analysis, trend analysis by Joinpoint Regression method and spatial analysis with Global Moran's and local statistics; 95% confidence interval and significance of 5% were considered in the analysis. Results There were 21,440 deaths in the study period, 50.4% (n=10,797) male, 40.5% (n=8,670) aged ≥ 80 years, 44.5% (n=9,465) of "brown" race, 30.1% (n=6,448) married and 36.5% (n=7,828) with less than four years of schooling. Female and male mortality rates were 460.24/100,000 and 602.23 / 100,000, respectively. An annual decreasing trend of -1.4% (p<0.001) in overall and male mortality was observed from 2007 on. The highest mortality rates were concentrated in the eastern region of Alagoas (Moran's I =0.766288; p=0.01). Twenty-two municipalities were in quadrant Q1 of Moran's scattering diagram and considered priorities. Conclusion Death from CVD in Alagoas occurred equally in men and women in the study period, mostly in individuals of mixed race, married, and with low education attainment. The highest rates were observed in the eastern region of the state . The results highlight the need for public policies aimed at healthy aging in the state.

Cause-specific mortality rates in patients with diabetes according to comorbid macro- and microvascular complications: BioBank Japan Cohort.

Objective: This study aimed to compare cause-specific mortality rates in patients with type 2 diabetes with and without various vascular complications. Methods: In Japanese hospitals, we followed up 30 834 patients with a mean age of 64.4 (standard deviation [SD]: 11.1) years. Patients were followed up from 2003 to 2007 for a median of 7.5 (interquartile range: 6.1-9.7) years. We calculated cause-specific mortality rates (number of deaths/1000 person-years) and confounder-adjusted hazard ratios in patients with macrovascular disease and in those with diabetic nephropathy, neuropathy and retinopathy, allowing for overlap of complications. Results: All-cause mortality rate was highest (51.4) in the nephropathy group, followed by the macrovascular disease group (45.2), the neuropathy group (39.5), the retinopathy group (38.7) and the nonvascular complication group (18.1). In the nephropathy group, morality rates of ischaemic heart, cerebrovascular, and infectious diseases and cancer were also highest among the groups. However, the cancer mortality rate was similar among the vascular complication groups. Relative to the nonvascular complication group, covariate-adjusted hazard ratios for ischaemic heart and cerebrovascular disease mortality were triple to quadruple in the macro- and microvascular complication groups. All-cause mortality rates rose exponentially according to age. Conclusion: Highest risks of all-cause, cancer, and ischaemic heart, infectious, and cerebrovascular disease mortality were determined in Japanese patients with diabetic nephropathy. Although cancer is the primary cause of death in Japanese patients with diabetes, cancer mortality rates are similar among those with and without vascular complications.

Frailty as a predictor of major adverse cardiac and cerebrovascular events after endovascular aortic aneurysm repair.

OBJECTIVE: To evaluate the effect of frailty assessed by the modified Frailty Index (mFI) on major adverse cardiac and cerebrovascular events (MACCE) in the elderly patients after endovascular aortic aneurysm repair (EVAR). METHODS: This was a retrospective cohort study of elderly patients who underwent EVAR in a tertiary hospital. The main exposure was frailty status assessed by the mFI. The primary outcomes were 30-day and long-term MACCE. The predictive ability of the mFI was compared with the Revised Cardiac Risk Index (RCRI) using net reclassification improvement (NRI) and integrated discrimination improvement (IDI) statistics. RESULTS: Of 749 participants, 134 (17.89%) were identified as frail and 185 (24.70%) as prefrail. Thirteen patients (1.74%) were lost in follow-up after surgery, and the median length of follow-up was 32.00 months (range, 15.00-59.25 months). Frailty was associated with a significantly increased risk of 30-day MACCE (adjusted odds ratio OR, 14.53; 95% confidence interval [CI], 4.59-46.04; P < .0001) and longer intensive care unit stay (adjusted odds ratio, 2.43; 95% CI, 1.17-5.07; P = .0176). As for long-term outcomes, both frailty and prefrailty were associated significantly increased risks of MACCE after EVAR (prefrail: adjusted hazard ratio [HR] 1.71; 95% CI, 1.12-2.61; frail: adjusted HR, 3.37; 95% CI, 1.86-6.10). When considering death as a competing risk, we also observed a significant association between frailty and cardiac and cerebrovascular events (adjusted HR, 2.95; 95% CI, 1.06-8.15). In addition, frailty was associated with a significantly increased risk of all-cause mortality (adjusted HR, 1.93; 95% CI, 1.28-2.90). Compared with the RCRI, the mFI had better discrimination in predicting 30-day MACCE (IDI: 0.225; 95% CI, 0.018-0.431; P = .033; NRI: 0.225; 95% CI, 0.023-0.427; P = .029) and long-term MACCE (IDI: 0.056; 95% CI, 0.018-0.128; P = .013; NRI: 0.237; 95% CI, 0.136-0.359; P < .001). CONCLUSIONS: Frailty assessed by the mFI may serve as a useful predictor of both short-term and long-term MACCE in elderly patients after EVAR, with improved discrimination and reclassification abilities compared with the RCRI.

Ten-year all-cause death following percutaneous or surgical revascularization in patients with prior cerebrovascular disease: insights from the SYNTAX Extended Survival study.

BACKGROUND: Coronary bypass artery grafting (CABG) has a higher procedural risk of stroke than percutaneous coronary intervention (PCI), but may offer better long-term survival. The optimal revascularization strategy for patients with prior cerebrovascular disease (CEVD) remains unclear. METHODS AND RESULTS: The SYNTAXES study assessed the vital status out to 10 year of patients with three-vessel disease and/or left main coronary artery disease enrolled in the SYNTAX trial. The relative efficacy of PCI vs. CABG in terms of 10 year all-cause death was assessed according to prior CEVD. The primary endpoint was 10 year all-cause death. The status of prior CEVD was available in 1791 (99.5%) patients, of whom 253 patients had prior CEVD. Patients with prior CEVD were older and had more comorbidities (medically treated diabetes, insulin-dependent diabetes, metabolic syndrome, peripheral vascular disease, chronic obstructive pulmonary disease, impaired renal function, and congestive heart failure), compared with those without prior CEVD. Prior CEVD was an independent predictor of 10 year all-cause death (adjusted HR: 1.35; 95% CI: 1.04-1.73; p = 0.021). Patients with prior CEVD had a significantly higher risk of 10 year all-cause death (41.1 vs. 24.1%; HR: 1.92; 95% CI: 1.54-2.40; p < 0.001). The risk of 10 year all-cause death was similar between patients receiving PCI or CABG irrespective of the presence of prior CEVD (p-interaction = 0.624). CONCLUSION: Prior CEVD was associated with a significantly increased risk of 10 year all-cause death which was similar in patients treated with PCI or CABG. These results do not support preferential referral for PCI rather than CABG in patients with prior CEVD. TRIAL REGISTRATION: SYNTAX: ClinicalTrials.gov reference: NCT00114972. SYNTAX Extended Survival: ClinicalTrials.gov reference: NCT03417050.

Risk factors associated with major adverse cardiac and cerebrovascular events following percutaneous coronary intervention: a 10-year follow-up comparing random survival forest and Cox proportional-hazards model.

BACKGROUND: Due to the limited number of studies with long term follow-up of patients undergoing Percutaneous Coronary Intervention (PCI), we investigated the occurrence of Major Adverse Cardiac and Cerebrovascular Events (MACCE) during 10 years of follow-up after coronary angioplasty using Random Survival Forest (RSF) and Cox proportional hazards models. METHODS: The current retrospective cohort study was performed on 220 patients (69 women and 151 men) undergoing coronary angioplasty from March 2009 to March 2012 in Farchshian Medical Center in Hamadan city, Iran. Survival time (month) as the response variable was considered from the date of angioplasty to the main endpoint or the end of the follow-up period (September 2019). To identify the factors influencing the occurrence of MACCE, the performance of Cox and RSF models were investigated in terms of C index, Integrated Brier Score (IBS) and prediction error criteria. RESULTS: Ninety-six patients (43.7%) experienced MACCE by the end of the follow-up period, and the median survival time was estimated to be 98 months. Survival decreased from 99% during the first year to 39% at 10 years' follow-up. By applying the Cox model, the predictors were identified as follows: age (HR = 1.03, 95% CI 1.01-1.05), diabetes (HR = 2.17, 95% CI 1.29-3.66), smoking (HR = 2.41, 95% CI 1.46-3.98), and stent length (HR = 1.74, 95% CI 1.11-2.75). The predictive performance was slightly better by the RSF model (IBS of 0.124 vs. 0.135, C index of 0.648 vs. 0.626 and out-of-bag error rate of 0.352 vs. 0.374 for RSF). In addition to age, diabetes, smoking, and stent length, RSF also included coronary artery disease (acute or chronic) and hyperlipidemia as the most important variables. CONCLUSION: Machine-learning prediction models such as RSF showed better performance than the Cox proportional hazards model for the prediction of MACCE during long-term follow-up after PCI.

Patient participation and associated factors in the discussions on do-not-attempt-resuscitation and end-of-life disclosure: a retrospective chart review study.

BACKGROUND: Patient participation is a key foundation of advance care planning (ACP). However, a patient himself/herself may be left out from sensitive conversations such as end-of-life (EOL) care discussions. The objectives of this study were to investigate patients' participation rate in the discussion of Cardiopulmonary Resuscitation (CPR) / Do-Not-Attempt-Resuscitation (DNAR) order, and in the discussion that the patient is at his/her EOL stage (EOL disclosure), and to explore their associated factors. METHODS: This is a retrospective chart review study. The participants were all the patients who were hospitalized and died in a university-affiliated teaching hospital (tertiary medical facility) in central Tokyo, Japan during the period from April 2018 to March 2019. The following patients were excluded: (1) cardiopulmonary arrest on arrival; (2) stillbirth; (3) under 18 years old at the time of death; and (4) refusal by their bereaved family. Presence or absence of CPR/DNAR discussion and EOL disclosure, patients' involvement in those discussions, and their associated factors were investigated. RESULTS: CPR/DNAR discussions were observed in 336 out of the 358 patients (93.9%). However, 224 of these discussions were carried out without a patient (patient participation rate 33.3%). Male gender (odds ratio (OR) = 2.37 [95% confidence interval (CI) 1.32-4.25]), living alone (OR = 2.51 [1.34-4.71]), and 1 year or more from the date of diagnosis (OR = 1.78 [1.03-3.10]) were associated with higher patient's participation in CPR/DNAR discussions. The EOL disclosure was observed in 341 out of the 358 patients (95.3%). However, 170 of the discussions were carried out without the patient (patient participation rate 50.1%). Patients who died of cancer (OR = 2.41[1.45-4.03]) and patients without mental illness (OR=2.41 [1.11-5.25]) were more likely to participate in EOL disclosure. CONCLUSIONS: In this clinical sample, only up to half of the patients participated in CPR/DNAR discussions and EOL disclosure. Female, living with family, a shorter period from the diagnosis, non-cancer, and mental illness presence are risk factors for lack of patients' participation in CPR/DNAR or EOL discussions. Further attempts to facilitate patients' participation, based on their preference, are warranted.

Competing risk analysis of cardiovascular/cerebrovascular death in T1/2 kidney cancer: a SEER database analysis.

BACKGROUND: Kidney cancer (KC) is associated with cardiovascular regulation disorder and easily leads to cardiovascular and cerebrovascular death (CCD), which is one of the major causes of death in patients with KC, especially those with T1/2 status. However, few studies have treated CCD as an independent outcome for analysis. We aimed to identify and evaluate the key factors associated with CCD in patients with T1/2 KC by competing risk analysis and compared these risk factors with those associated with kidney cancer-specific death (KCD) to offer some information for clinical management. METHODS: A total of 45,117 patients diagnosed with first primary KC in T1/2 status were obtained from the Surveillance, Epidemiology, and End Results (SEER) database. All patients were divided into the CCD group (n = 3087), KCD group (n = 3212), other events group (n = 6312) or alive group (n = 32,506). Patients' characteristics were estimated for their association with CCD or KCD by a competing risk model. Pearson's correlation coefficient and variance inflation factor (VIF) were used to detect collinearity between variables. Factors significantly correlated with CCD or KCD were used to create forest plots to compare their differences. RESULTS: The competing risk analysis showed that age at diagnosis, race, AJCC T/N status, radiation therapy, chemotherapy and scope of lymph node represented different relationships to CCD than to KCD. In detail, age at diagnosis (over 74/1-50: HR = 9.525, 95% CI: 8.049-11.273), race (white/black: HR = 1.475, 95% CI: 1.334-1.632), AJCC T status (T2/T1: HR = 0.847, 95% CI: 0.758-0.946) and chemotherapy (received/unreceived: HR = 0.574, 95% CI: 0.347-0.949) were correlated significantly with CCD; age at diagnosis (over 74/1-50: HR = 3.205, 95% CI: 2.814-3.650), AJCC T/N status (T2/T1: HR = 2.259, 95% CI: 2.081-2.451 and N1/N0:HR = 3.347, 95% CI: 2.698-4.152), radiation therapy (received/unreceived: HR = 2.552, 95% CI: 1.946-3.346), chemotherapy (received/unreceived: HR = 2.896, 95% CI: 2.342-3.581) and scope of lymph nodes (1-3 regional lymph nodes removed/none: HR = 1.378, 95% CI: 1.206-1.575) were correlated significantly with KCD. CONCLUSIONS: We found that age at diagnosis, race, AJCC T status and chemotherapy as the independent risk factors associated with CCD were different from those associated with KCD.

Ischaemic heart and cerebrovascular disease mortality in uranium enrichment workers.

OBJECTIVE: Linear and non-linear dose-response relationships between radiation absorbed dose to the lung from internally deposited uranium and external sources and circulatory system disease (CSD) mortality were examined in a cohort of 23 731 male and 5552 female US uranium enrichment workers. METHODS: Rate ratios (RRs) for categories of lung dose and linear excess relative rates (ERRs) per unit lung dose were estimated to evaluate the associations between lung absorbed dose and death from ischaemic heart disease (IHD) and cerebrovascular disease. RESULTS: There was a suggestion of modestly increased IHD risk in workers with internal uranium lung dose above 1 milligray (mGy) (RR=1.4, 95% CI 0.76 to 2.3) and a statistically significantly increased IHD risk with external dose exceeding 150 mGy (RR=1.3, 95% CI 1.1 to 1.6) compared with the lowest exposed groups. ERRs per milligray were positive for IHD and uranium internal dose and for both outcomes per gray external dose, although the CIs generally included the null. CONCLUSIONS: Non-linear dose-response models using restricted cubic splines revealed sublinear responses at lower internal doses, suggesting that linear models that are common in radioepidemiological cancer studies may poorly describe the association between uranium internal dose and CSD mortality.
