Cardiovascular-specific mortality and risk factors in colorectal Cancer patients: A cohort study based on registry data of over 500,000 individuals in the US.

BACKGROUND: Colorectal cancer (CRC) is one of the most common cancers worldwide, and recent studies have found that CRC patients are at increased risk for cardiovascular disease (CVD). This study aimed to investigate competing causes of death and prognostic factors among a large cohort of CRC patients and to describe cardiovascular-specific mortality in relation to the US standard population. METHODS: This registry-based cohort study identified patients diagnosed with CRC between 1973 and 2015 from the Surveillance, Epidemiology, and End Results (SEER) database in the US. Cumulative mortality functions, conditional standardized mortality ratios, and cause-specific hazard ratios were calculated. RESULTS: Of the 563,298 eligible CRC patients included in this study, 407,545 died during the follow-up period. CRC was the leading cause of death, accounting for 49.8% of all possible competing causes of death. CVD was the most common non-cancer cause of death, accounting for 17.8% of total mortality. This study found that CRC patients have a significantly increased risk of cardiovascular-specific mortality compared to the US standard population, with the risk increasing with age and extended survival time. CONCLUSION: This study highlights the need to develop multidisciplinary prevention and management strategies for CRC and CVD to improve CRC patients' survival and quality of life.

Study of the excess mortality associated with the SARS-CoV-2 pandemic in the Local Health Authorities and Districts of the Autonomous Region of Sardinia - quinquennium 2017-2021.

Background: Based on the indications of the Italian National Recovery and Resilience Plan and the Ministerial Decree n°77/2022, detecting specific populations' social-welfare needs is essential to reorganize the national and regional health service. The present analysis studies the impact of pandemic and pre-pandemic conditions in terms of mortality on Sardinian health service organizational subunits to indirectly investigate the need for specific social and health interventions. Design: Retrospective observational mortality study on the Sardinian resident population, surveyed by the Italian National Institute of Statistics (Istat) from 2017 to 2021. Methods: The database was built by crossing demographic data from the Istat divided into 21 five-year age groups (0-4 to 100+). Mortality and excess mortality were calculated with a focus on local health authorities and districts. The analysis were made considering three age groups (0-64, ≥ 65, 0-100+) and comparing the individual years 2020 and 2021 with the pre-pandemic triennium 2017-2019. To better understand the phenomenon of excess mortality, the old age index was calculated for the Local Health Authority and District for each year of the quinquennium considered. Results: Standardized mortality ratios increased in the biennium of the SARS-CoV-2 pandemic compared to the baseline 2017-2019. A global increaseof the Standardized mortality ratios in all districts (2021) was measured, including those with Standardized mortality ratios already increasing in 2020. Notably, the Standardized mortality ratios (2020 and 2021) were often increased by the 0-64 age group. The regional excess mortality (0-100+) confirmed an increase in mortality compared to the baseline, with a slight decrease from 2020 to 2021. Conclusions: Sardinia presents peculiar demographic and geographical characteristics. Monitoring mortality rates and excess mortality confirms to be crucial to constantly re-modulating health interventions and planning of the supply of services, including the equitable allocation of resources based on actual health needs. Sardinia should embrace the concept of "age-friendly community" and create communities designed to promote active aging and social participation.

Conditional survival among patients with oropharyngeal cancer treated with radiation therapy and alive without recurrence 5 years after diagnosis.

BACKGROUND: Risk of recurrence among patients with oropharyngeal cancer (OPC) who survive 5 years is low. The goal of this study was to assess long-term survival of patients with OPC alive without recurrence 5 years after diagnosis. METHODS: This study included newly diagnosed patients with OPC, who had been treated with radiation and were alive without recurrence 5 years after diagnosis. Overall survival (OS) probabilities beyond 5 years were estimated using the Kaplan-Meier method. Factors associated with OS were determined using Bayesian piecewise exponential survival regression. Standardized mortality ratios for all-cause death were estimated controlling for study year, age, and sex in the US general population. RESULTS: Among 1699 patients, the additional 2-year, 5-year, and 10-year OS probabilities were 94%, 83%, and 63%, respectively, and were lower than those in the general population. Patients who were older, were current or former smokers, had other than tonsil or base of tongue tumors, or had T4 tumors had a higher risk of death. Patients who had base of tongue tumors and had received intensity-modulated radiation therapy (IMRT) or lower-radiation doses had a lower risk of death. Standardized mortality ratios were higher among current and heavy smokers and lower among recipients of IMRT and lower radiation doses. CONCLUSIONS: In this large cohort, long-term survival among patients with OPC was good but lower than predicted for the general population. Patients treated with IMRT and those with less tobacco exposure had better outcomes.

Immediate risk of non-cancer deaths after a cancer diagnosis.

BACKGROUND: Receiving a cancer diagnosis may trigger immediate fatal non-cancer health outcomes in addition to dying of cancer itself. We aim to investigate the full pattern of non-cancer deaths in patients within a year of a cancer diagnosis. METHODS: Patients diagnosed with cancer between 1990 and 2016 were identified from the SEER program. Standardized mortality ratios (SMRs) were calculated to characterize the relative risks of non-cancer deaths compared with the general population. RESULTS: Among 7,366,229 patients, 241,575 non-cancer deaths (15.9%) were recorded in the first year following a cancer diagnosis. The relative risk of non-cancer deaths was 2.34-fold (95% confidence interval (CI): 2.33-2.35) that of the general population. The majority of non-cancer deaths were caused by cardiovascular diseases (21.8%), followed by infectious diseases (7.2%). Significant elevations in mortality risks were observed for nearly all non-cancer causes, particularly in infectious diseases (SMR: 5.08; 95% CI: 5.03-5.13). Patients with liver cancer (SMR: 12.29; 95% CI: 12.06-12.53) were at the highest risk of early non-cancer deaths. The risks of non-cancer deaths were highest within the first month after diagnosis, and decreased rapidly thereafter. CONCLUSIONS: Risks of non-cancer deaths vary by the types of causes and anatomic sites of cancer. Our data underscore the importance of close observation and early multidisciplinary care for noncancer conditions in patients who have recently received a cancer diagnosis.

A Bayesian spatio-temporal analysis of mortality rates in Spain: application to the COVID-19 2020 outbreak.

BACKGROUND: The number of deaths attributable to COVID-19 in Spain has been highly controversial since it is problematic to tell apart deaths having COVID as the main cause from those provoked by the aggravation by the viral infection of other underlying health problems. In addition, overburdening of health system led to an increase in mortality due to the scarcity of adequate medical care, at the same time confinement measures could have contributed to the decrease in mortality from certain causes. Our aim is to compare the number of deaths observed in 2020 with the projection for the same period obtained from a sequence of previous years. Thus, this computed mortality excess could be considered as the real impact of the COVID-19 on the mortality rates. METHODS: The population was split into four age groups, namely: (< 50; 50-64; 65-74; 75 and over). For each one, a projection of the death numbers for the year 2020, based on the interval 2008-2020, was estimated using a Bayesian spatio-temporal model. In each one, spatial, sex, and year effects were included. In addition, a specific effect of the year 2020 was added ("outbreak"). Finally, the excess deaths in year 2020 were estimated as the count of observed deaths minus those projected. RESULTS: The projected death number for 2020 was 426,970 people, the actual count being 499,104; thus, the total excess of deaths was 72,134. However, this increase was very unequally distributed over the Spanish regions. CONCLUSION: Bayesian spatio-temporal models have proved to be a useful tool for estimating the impact of COVID-19 on mortality in Spain in 2020, making it possible to assess how the disease has affected different age groups accounting for effects of sex, spatial variation between regions and time trend over the last few years.

Suicidality among adult survivors of childhood cancer: A report from the St. Jude Lifetime Cohort Study.

BACKGROUND: Suicide is a serious public health concern. An increased risk of suicide ideation previously has been reported among survivors of childhood cancer. METHODS: Suicide mortality was assessed for all potentially eligible survivors (those aged ≥18 years who were ≥5 years after their cancer diagnosis; 7312 survivors). Risk factors for acute suicidal ideation were assessed among clinically evaluated survivors (3096 survivors) and the prevalence of acute ideation was compared with that of community controls (429 individuals). The prevalence of 12-month suicidality was assessed among survivors who could be compared with population data (1255 survivors). Standardized mortality ratios compared rates of suicide mortality among survivors with those of the general population. Risk ratios (RRs) and 95% confidence intervals (95% CIs) derived from generalized linear models identified risk factors associated with acute suicidal ideation. Standardized incidence ratios (SIRs) compared the prevalence of 12-month suicidality among survivors with that of a matched sample from the general population. RESULTS: Survivors reported a similar 12-month prevalence of ideation compared with the general population (SIR, 0.68; 95% CI, 0.35-1.01) and a lower prevalence of suicidal behaviors (planning: SIR, 0.17 [95% CI, 0.07-0.27]; attempts: SIR, 0.07 [95% CI, 0.00-0.15]) and mortality (standardized mortality ratio, 0.60; 95% CI, 0.34-0.86). Among survivors, depression (RR, 12.30; 95% CI, 7.89-19.11), anxiety (RR, 2.19; 95% CI, 1.40-3.40), and financial stress (RR, 1.47; 95% CI, 1.00-2.15) were found to be associated with a higher prevalence of acute suicidal ideation. CONCLUSIONS: Survivors of childhood cancer were found to be at a lower risk of suicidal behaviors and mortality, yet endorsed a prevalence of ideation similar to that of the general population. These results are in contrast to previous findings of suicidal ideation among survivors and support the need for further research to inform screening strategies and interventions. LAY SUMMARY: The purpose of the current study was to compare the risk of suicidal ideation, behaviors, and mortality in adult survivors of childhood cancer with those of the general population. Risk factors associated with suicidal ideation among survivors of childhood cancer also were examined. Survivors of childhood cancer reported a similar risk of ideation compared with the general population, but a lower risk of suicidal behaviors and mortality. Psychological health and financial stressors were found to be risk factors associated with suicidal ideation. Although adult survivors of childhood cancer did not report a greater risk of suicidality compared with the general population, psychosocial care in survivorship remains essential.

Causes that Contribute to the Excess Mortality Risk in Multiple Sclerosis: A Population-Based Study.

BACKGROUND: Lifespan is 6-10 years shorter in multiple sclerosis (MS), but the reasons remain unclear. Using linked clinical- and population-based administrative health databases, we compared cause-specific mortality in an MS cohort to the general population. METHODS: MS patients in British Columbia (BC), Canada, were followed from the later of first MS clinic visit or January 1, 1986, to the earlier of death, emigration, or December 31, 2013. Comprehensive mortality information was obtained by linkage to BC's multiple-cause-of-death mortality data. Causes were grouped using International Classification of Disease codes. Standardized mortality ratios (SMRs) were calculated for underlying cause, and relative mortality ratios (RMRs) for any mention cause, by comparison to mortality rates in the age-, sex-, and calendar year-matched general population. Cause-specific relative mortality was explored by sex and disease course (relapsing onset and primary progressive). RESULTS: Among 6,629 MS patients with 104,236 patient-years of follow-up, 1,416 died. The all-cause mortality risk was increased relative to the general population (SMR 2.71; 95% CI 2.55-2.87). MS was the underlying cause in 50.4%, and a mentioned cause in 77.9%, of deaths. Mortality by underlying cause was higher than expected for genitourinary disorders/infections (SMR 3.55; 95% CI 2.25-5.32), respiratory diseases/infections (SMR 2.69; 95% CI 2.17-3.28), suicide (SMR 2.40; 95% CI 1.61-3.45), cardiovascular disease (SMR 1.57; 95% CI 1.36-1.81), and other infections/septicemia (SMR 1.83; 95% CI 1.15-2.78). Risks of death due to overall cancer, accidents, digestive system disorders, and endocrine/nutritional diseases as underlying causes were similar to the general population. However, mortality with any mention of accidents (RMR 2.71; 95% CI 2.22-3.29) or endocrine/nutritional diseases (RMR 1.75; 95% CI 1.46-2.09) was greater. Bladder cancer mortality was increased in women (SMR 3.87; 95% CI 1.42-8.42) but not men. No notable differences were observed by disease course. CONCLUSIONS: MS itself was the most frequent underlying cause of death. Infections (genitourinary, respiratory, and septicemia), suicides, cardiovascular disease, and accidents contributed significantly to the increased risk of death. Some findings differed by sex, but not disease course. Multiple-cause death data offer advantages over "traditional" use of underlying cause only.

Acute and Delayed Deaths after West Nile Virus Infection, Texas, USA, 2002-2012.

Infection with West Nile virus (WNV) has a well-characterized acute disease process. However, long-term consequences are less understood. We searched death records for 4,142 residents of Texas, USA, infected with WNV during 2002-2012 and identified 557 (13%) deaths. We analyzed all-cause and cause-specific deaths after WNV infection by calculating standardized mortality ratios and using statewide mortality data. Acute-phase deaths (<90 days after symptom onset) occurred in 289 (7%) of case-patients; of those deaths, 289 (92%) were cases of West Nile neuroinvasive disease (WNND). Convalescent-phase deaths (>90 days after symptom onset) occurred in 268 (7%) of the remaining 3,853 case-patients; 210 (78%) of these deaths occurred in patients with WNND. Convalescent-phase WNND case-patients showed excess deaths from infectious and renal causes; case-patients <60 years of age had increased risk for all-cause death, specifically from renal, infectious, digestive, and circulatory causes. We provide population-level evidence of increased risk for death after WNV infection resulting in WNND.

Mortality of patients with haemophilia in Brazil: First report.

INTRODUCTION: Brazil has the fourth largest world population of patients with haemophilia. However, mortality rates in this population are unknown. AIM: To analyse mortality and its causes in Brazilian patients with haemophilia from 2000 to 2014. METHODS: The number of deceased patients with haemophilia and causes of death were obtained from the Brazilian National Mortality Information System (SIM), according to the 10th International Classification of Diseases (ICD-10). Standardized mortality ratios (SMR) were calculated to estimate the rate of overall death of patients with haemophilia relative to that of the Brazilian general male population. RESULTS: A total of 784 deaths were identified in the period of 15 years. Mortality of patients with haemophilia was 13% higher when compared with the general male population (SMR 1.13, 95% CI: 1.01-1.16). Haemorrhage was the main cause of death (n = 254; 32.4%) of which 137 (54%) was intracranial haemorrhage. The total number of deaths due to HIV decreased over the years, and an increase in deaths due to cancer and cardiovascular disease was observed. A total of 129 deaths (16.5%) were related to hepatitis infection, of whom, 109 (86.5%) patients also presented with cirrhosis and hepatocellular carcinoma or other liver diseases. CONCLUSION: Mortality rate of Brazilian patients with haemophilia decreased over the evaluated period. Intracranial haemorrhage is still an important cause of death in these patients, which requires major effort for prevention. Death due to age-related cardiovascular disease and cancer has increased over the years, following the same tendency observed in developed countries.

[Trends in stroke mortality rates in Russia and the USA over a 15-year period]. / Dinamika pokazatelei smertnosti naseleniia ot ostrogo narusheniia mozgovogo krovoobrashcheniia v Rossii i SShA za 15-letnii period.

AIM: to comparatively analyze standardized mortality ratios (SMR) from stroke in the populations aged over 30 years in the Russian Federation and in the USA over a 15-year period. MATERIAL AND METHODS: The analysis included nontraumatic subarachnoid hemorrhage (NTSH) (a group of ICD-10 codes I60), nontraumatic intracerebral hemorrhage (NTIH) (I61), cerebral infarction (CI) (I63), and stroke, not specified as hemorrhage or infarction (SNSHI) (I64). The new European standard (European Standard Population.2013) was used for standardization. The data of the Federal State Statistics Service of the Russian Federation, those of the World Health Organization Mortality Database (WHO MD) and Human Mortality Database (HMD) for the USA were applied. RESULTS: During the considered period, 30-49-year-old Russian men showed a reduction in SMRs from NTSH (I61) by 9.0% (from 18.9 to 17.2 per 100,000 population), from SNSHI (I64) by 10 times (from 12.5 to 1.3); SMRs from CI (I63) increased by 4.3% (from 6.9 to 7.2). In men aged 50 years and older, SMRs from NTIH and SNSHI decreased by 32.3% (from 143.2 to 97.0) and by 10 times (from 580.8 to 60.6), respectively; those from CI increased by 13.8% (from 229.8 to 261.4). In the USA, 30-49-year-old men displayed 26.1% and 2-fold decreases in SMRs from NTIH (from 2.5 per 100,000 population in 1999 to 1.7 in 2013) and CI (from 1.8 to 0.9), respectively; those from SNSHI remained unchanged (1.3). In men aged 50 years and older, SMRs from NTIH, CI, and SNSHI reduced by 39.7% (from 29.0 to 17.5), by 2 times (from 1.8 to 0.9), and by 2 times (143.0 to 72.5), respectively. 30-49-year-old Russian women exhibited a 22.2% reduction in SMRs from NTIH (from 9.0 to 7.0), a 4.3% increase in those from CI (from 2.7 to 2.8), and an 11-fold decrease in those from SNSHI (from 5.5 to 0.5). Women aged 50 years and older showed changes in SMRs from the codes in the same sequence from 105.6 to 60.5, from 172.8 to 189.6, and from 466.5 to 43.7, respectively. In the USA, 30-49-year-old women displayed reductions in SMRs from NTIH by 10.0% (from 1.5 to 0.9), from CI by 33.3% (from 0.3 to 0.2), and from SNSHI by 10% (from 1.0 to 0.9). Women aged 50 years and older exhibited changes in SMRs from the codes in the same sequence from 24.0 to 14.8), n those from CI (from 20.6 to 6.7) and from SNSHI (from 6.5 to 10.3). CONCLUSION: In Russia, the reduction in mortality rates from the above causes (which is most significant from that in NTSH may be associated with both medical and socioeconomic factors, including with the improved prevention and organization of medical care. The differences in SMRs between the two countries may be related to the principles in the organization and control of coding of the causes of death.

Overall and cause-specific mortality in Korean patients with inflammatory bowel disease: A hospital-based cohort study.

BACKGROUND AND AIM: Limited data are available regarding mortality from inflammatory bowel disease in non-Caucasian populations. Herein, we evaluated overall and cause-specific mortality in a hospital-based cohort of Korean inflammatory bowel disease patients. METHODS: We determined mortality in 2414 Crohn's disease patients and 2798 ulcerative colitis patients diagnosed between 1977 and 2013. Standardized mortality ratios were calculated in several demographic and phenotypic subgroups. RESULTS: During the mean 9-year follow up, 114 patients died: 35 with Crohn's disease and 79 with ulcerative colitis. The overall standardized mortality ratios were 1.40 (95% confidence interval: 0.97-1.94) in Crohn's disease and 0.73 (0.58-0.91) in ulcerative colitis. In Crohn's disease, female sex, age < 30 years at diagnosis, disease duration > 10 years, ileocolonic disease at diagnosis, perianal fistula, intestinal resection, and ever-use of corticosteroids were associated with higher mortality. In ulcerative colitis, male sex, age ≥ 30 years at diagnosis, disease duration ≤ 5 years, proctitis at diagnosis, and no history of colectomy were associated with lower mortality, while primary sclerosing cholangitis was associated with higher mortality. In both Crohn's disease and ulcerative colitis, high mortality rates due to nonmalignant gastrointestinal causes (standardized mortality ratios: 4.59 and 2.32, respectively) and gastrointestinal malignancies (standardized mortality ratios: 16.59 and 3.45, respectively) were observed. Cardiovascular mortality was lower in ulcerative colitis (standardized mortality ratio: 0.47). CONCLUSIONS: The overall mortality tended to be higher in Crohn's disease patients than in the general population; it was slightly lower in ulcerative colitis patients than in the general population.

Mortality in a combined cohort of uranium enrichment workers.

OBJECTIVE: To examine the patterns of cause-specific mortality and relationship between internal exposure to uranium and specific causes in a pooled cohort of 29,303 workers employed at three former uranium enrichment facilities in the United States with follow-up through 2011. METHODS: Cause-specific standardized mortality ratios (SMRs) for the full cohort were calculated with the U.S. population as referent. Internal comparison of the dose-response relation between selected outcomes and estimated organ doses was evaluated using regression models. RESULTS: External comparison with the U.S. population showed significantly lower SMRs in most diseases in the pooled cohort. Internal comparison showed positive associations of absorbed organ doses with multiple myeloma, and to a lesser degree with kidney cancer. CONCLUSION: In general, these gaseous diffusion plant workers had significantly lower SMRs than the U.S. POPULATION: The internal comparison however, showed associations between internal organ doses and diseases associated with uranium exposure in previous studies. Am. J. Ind. Med. 60:96-108, 2017. Published 2016. This article is a U.S. Government work and is in the public domain in the USA.

A study update of mortality in workers at a phosphate fertilizer production facility.

OBJECTIVE: To evaluate the mortality experience among 3,199 workers employed 1951-1976 at a phosphate fertilizer production plant in central Florida with follow-up through 2011. METHODS: Cause-specific standardized mortality ratios (SMRs) for the full cohort were calculated with the U.S. population as referent. Lung cancer and leukemia risks were further analyzed using conditional logistic regression. RESULTS: The mortality due to all-causes (SMR = 1.07, 95% confidence interval [CI] 1.02-1.13, observed deaths [n] = 1,473), all-cancers (SMR = 1.16, 95%CI 1.06-1.28, n = 431), and a priori outcomes of interests including lung cancer (SMR = 1.32, 95%CI = 1.13-1.53, n = 168) and leukemia (SMR = 1.74, 95%CI = 1.11-2.62, n = 23) were statistically significantly elevated. Regression modeling on employment duration or estimated radiation scores did not show exposure-response relation with lung cancer or leukemia mortality. CONCLUSION: SMR results showed increased lung cancer and leukemia mortality in a full cohort of the phosphate fertilizer production facility. There was, however, no exposure-response relation observed among cases and matched controls.

Mapping the Grounds for Mortalities in Acute Myeloid Leukemia Through Registry Analyses: A Retrospective Cohort Study of Children, Adolescents, and Young Adults Patients.

Background: Our objective was to identify non-malignant factors that contribute to mortality in children, adolescents and young adults, aiming to improve patient follow-up and reduce mortality rates to achieve better survival outcomes. Methods: We analyzed 8,239 acute myeloid leukemia (AML) cases diagnosed between 2000 and 2019 in the USA. Using version 8.4.0.1 of the Surveillance, Epidemiology, and End Results (SEER)*Stat software, we calculated the standardized mortality ratios (SMRs) and 95% confidence intervals (CIs) for each cause of death. Results: Out of the 3,165 deaths observed in the study population, the majority (2,245;70.9%) were attributed to AML itself, followed by non-AML cancers (573; 18.1%) and non-cancerous causes (347; 10.9%). Conclusions: Patients with AML are at a higher risk of developing other types of cancer and granulocyte deficiencies, which increases the risk of death from non-cancerous causes such as infections. Moreover, treatment for AML carries the risk of cardiac problems. AML is commoner in males than females.

Cause-specific mortality after hospital discharge for suicide attempt or suicidal ideation: A cohort study in Piedmont Region, Italy.

BACKGROUND: Suicide attempters are at higher risk of death than the general population. The present study aims to investigate the excess of all-cause mortality and cause-specific mortality in a cohort of patients who have attempted suicide or had suicidal ideation compared with the general population. METHOD: The cohort included 826 patients residing in the Piedmont Region of Northwest Italy who were admitted to a hospital or emergency department for suicide attempts or suicidal ideation between 2010 and 2016. Mortality excesses of the study population compared to the general population were estimated by applying indirect standardization. Standardized Mortality Ratios and 95% Confidence Intervals were calculated for all-cause, and cause-specific, natural, and unnatural causes of death by gender and age. RESULTS: During the 7 years of follow-up, 8.2% of the study sample died. The mortality of suicide attempters and ideators was significantly higher than that of the general population. Mortality was about twice than expected from natural causes, and 30 times than expected from unnatural causes. The mortality due to suicide was 85 times higher than that of the general population, with an excess of 126 times for females. The SMRs for all-cause mortality decreased with increasing age. CONCLUSIONS: Patients who access hospitals or emergency departments for suicide attempts or suicidal ideation are a frail group at high risk of dying from natural or unnatural causes. Clinicians should pay special attention to the care of these patients, and public health and prevention professionals should develop and implement appropriate interventions to timely identify individuals at higher risk for suicide attempts and suicidal ideation and provide standardized care and support services.

At What Point Are Long-Term (>5 Years) Survivors of APL Safe? A Study from the SEER Database.

BACKGROUND: Acute promyelocytic leukemia (APL) is a highly curable cancer, but it is not clear whether it is also necessary to monitor long-term toxicity in "cured" patients who survive for more than five years, which is critical to ensuring maximum survival in APL patients. METHODS: A total of 1952 APL 5-year survivors and 5973 non-APL acute myeloid leukemia (AML) 5-year survivors were included from the Surveillance, Epidemiology, and End Results (SEER) database. The standardized mortality ratio (SMR) was calculated to measure the risk of death. Cumulative mortality is calculated as the incidence of specific causes of death under competing risk events. RESULTS: The SMR of all causes of death in >5-year survivors of APL was higher than that of the general population only at 60-119 months (SMR, 1.41). This was mainly because a significant increase in mortality from AML (SMR, 87.67) and second malignant neoplasms (SMNs) (SMR, 1.56) was found only at 60-119 months. However, there was no higher risk of death from non-cancer-related disease in >5-year survivors of APL than that of the general population (SMR, 0.89). The SMR of all-cause deaths in >5-year survivors of non-APL AML decreased year by year and was no higher than that of the general population until after 216 months. The cumulative incidence of AML-related death, SMN-related death, and non-cancer-related death was significantly lower in APL patients than in non-APL AML patients throughout the follow-up period. CONCLUSIONS: Compared with the general population, the risk of death of patients with APL was higher within 5 to 10 years but not higher over 10 years. Therefore, we believe that long-term survivors of APL are safe after 10 years.

Cause of death during nasopharyngeal carcinoma survivorship: a population-based analysis.

Background: Recently, the survival rate of nasopharyngeal carcinoma (NPC) patients has improved greatly due to developments in NPC treatments. But cause-specific mortality in NPC patients remains unclear. This study aims to investigate the common causes of death in NPC patients. Methods: Eligible patients with NPC were included from the Surveillance, Epidemiology, and End Results (SEER) database. Standardized mortality ratios(SMRs) were calculated to compare death rates in NPC patients with those in the general population. Results: A total of 3475 patients with NPC were included, of whom 1696 patients died during the follow-up period. 52.83% of deaths were caused by NPC, followed by other cancers (28.13%) and non-cancer causes (18.46%). The proportion of patients who died of NPC decreased over survival time. Moreover, non-cancer causes of death increase from 12.94% to 51.22% over time after 10 years of diagnosis. Heart diseases was the most common non-cancer cause of death in NPC patients. Conclusions: Although NPC remains the leading cause of death after NPC diagnosis, other non-NPC causes of death represent an increased number of death in NPC patients. These findings support the involvement of multidisciplinary care for follow-up strategy in NPC patients.

Sex differences in the generalizability of randomized clinical trials in heart failure with reduced ejection fraction.

AIMS: In order to understand how sex differences impact the generalizability of randomized clinical trials (RCTs) in patients with heart failure (HF) and reduced ejection fraction (HFrEF), we sought to compare clinical characteristics and clinical outcomes between RCTs and HF observational registries stratified by sex. METHODS AND RESULTS: Data from two HF registries and five HFrEF RCTs were used to create three subpopulations: one RCT population (n = 16 917; 21.7% females), registry patients eligible for RCT inclusion (n = 26 104; 31.8% females), and registry patients ineligible for RCT inclusion (n = 20 810; 30.2% females). Clinical endpoints included all-cause mortality, cardiovascular mortality, and first HF hospitalization at 1 year. Males and females were equally eligible for trial enrolment (56.9% of females and 55.1% of males in the registries). One-year mortality rates were 5.6%, 14.0%, and 28.6% for females and 6.9%, 10.7%, and 24.6% for males in the RCT, RCT-eligible, and RCT-ineligible groups, respectively. After adjusting for 11 HF prognostic variables, RCT females showed higher survival compared to RCT-eligible females (standardized mortality ratio [SMR] 0.72; 95% confidence interval [CI] 0.62-0.83), while RCT males showed higher adjusted mortality rates compared to RCT-eligible males (SMR 1.16; 95% CI 1.09-1.24). Similar results were also found for cardiovascular mortality (SMR 0.89; 95% CI 0.76-1.03 for females, SMR 1.43; 95% CI 1.33-1.53 for males). CONCLUSION: Generalizability of HFrEF RCTs differed substantially between the sexes, with females having lower trial participation and female trial participants having lower mortality rates compared to similar females in the registries, while males had higher than expected cardiovascular mortality rates in RCTs compared to similar males in registries.
