Background/Objectives: Orofacial clefts are congenital anomalies that cause substantial morbidity and mortality. This study aimed to investigate temporal and geographic trends in mortality among Brazilian individuals with orofacial clefts listed as the underlying cause of death on death certificates. Methods: A retrospective cross-sectional study was conducted using data from the Department of Informatics of the Brazilian Unified Health System (DATASUS) from 1996 to 2023. Results: The mortality information system registered 987 deaths related to orofacial clefts, with 880 patients under 1 year of age. There was a downward trend in annual mortality rates from 1996 to 2019, followed by an increase from 2020 to 2023. The main associated cause of death was respiratory and cardiovascular disorders. The mortality rate for infants under 1 year with orofacial clefts showed greater variation than did the mortality rate of children who died of other causes. The reduction in mortality rates from 1996 to 2019 occurred during the expansion and strengthening of DATASUS and its coordination with other levels of healthcare. The rise in mortality between 2020 and 2023 coincided with a reduction in surgical procedures due to the COVID-19 pandemic. Conclusions: This study revealed a decline in deaths from orofacial clefts in Brazil over several decades. These findings emphasize the importance of addressing preventable causes of death, including respiratory infections and malnutrition. High mortality within the first year of life—particularly among newborns under 28 days—highlights a critical shortage of pediatricians and its impact on care for individuals with craniofacial anomalies.

Background: Myocarditis is a life-threatening condition with an increasing incidence in the past two decades. Little is known about the frequency of specific causes of death following myocarditis. This study aimed to identify the different causes of death after myocarditis diagnosis and determine factors associated with mortality. Methods: We conducted a retrospective population-wide observational study in New South Wales (NSW), Australia from July 2004 to September 2021. Data were attained from the NSW Admitted Patient Data Collection database and death was tracked from the death registry to 31 March 2022. Cause of death was ascertained from manual reviews of all death certificates and adjudicated independently by three reviewers. Results: Among 4071 unique index admissions for myocarditis (median age: 42 years; 66% male), cumulative all-cause mortality was 4.5% in-hospital, 8.2% at 1 year, 13.3% at 5 years and 15.5% by the end of follow up (median 5.3 years). Within 30 days of admission, the leading cause of death was cardiovascular (66%), including myocarditis (36%) and heart failure (12%). Non cardiovascular causes accounted for 32% of deaths and included infection (17%) and malignancy (6%). Beyond 30 days, cardiovascular deaths declined to 34% (only 3% due to myocarditis). Higher mortality risk was associated with older age, higher Charlson comorbidity index, and myocarditis complicated by intensive care unit admission, heart failure, stroke, or arrhythmia. Conclusions: Patients admitted with myocarditis face significant mortality risks. The highest mortality occurs within the first 30 days, predominantly due to cardiovascular causes, although after 30 days the predominant cause of death shifts to non-cardiovascular causes.

Background: Cardiovascular disease (CVD) significantly impacts Alzheimer’s Disease and Related Dementia (AD/ADRD) mortality. South Carolina has a high incidence of CVD and dementia mortality. The aim of this study, therefore, was to examine the neurological causes of death and the leading causes of death in the South Carolina Alzheimer’s Disease Registry (SCADR). Method: Data from 2005–2018 were extracted from the SCADR using ICD-9 and ICD-10 codes. The top 10 leading causes of death (LCOD) were identified using death certificates. Some neurological causes of death were operationalized by combining related ICD codes, such as CVD_C (I219, I251, I500, I64) and chronic obstructive pulmonary disease (COP_C), (J449, C349), and ${\chi }^2$ was used to compare socio-demographic characteristics and mortality. Adjusted hazard ratios (aHR) and 95% confidence intervals (CI) were estimated using extended Cox Proportional Hazard modeling, adjusting for socio-demographic factors. Results: A total of 207,093 registry cases were included in the analysis. About 70% of cases had Alzheimer’s Disease (AD) diagnosis, and 40% of all cases were 85 years and older. The LCOD was CVD_C (13.4%). The risk of death among cases with vascular dementia (VaD) was 1.17 times the risk of death among those with AD (aHR: 1.172, 95% CI: 1.148–1.196). Among all deaths, cases with COP_C had a significantly higher likelihood of death compared to those with CVD_C (aHR: 1.06, 95% CI: 1.025–1.090). Conclusions: The study highlights CVD_C as the LCOD in frequency, with survival analysis indicating COP_C risk of death as significantly higher compared to CVD_C deaths. There is a need to prioritize CVD and lung-related comorbidity prevention, assessment, and management programs for individuals living with ADRD. Full article

Background and Objectives: Growing evidence suggests a strong relationship between hypertension and cancer, which can increase the risk of poor prognosis. However, data regarding mortality related to cancer and hypertension are limited. Our study aims to analyze the mortality trends related to cancer and hypertension in the United States from 1999 to 2023. Materials and Methods: A retrospective observational analysis was conducted using mortality data for the adult U.S. population from 1999 to 2023, retrieved from the CDC WONDER database using death certificates. Age-adjusted mortality rates (AAMRs) were calculated, and annual percentage changes (APCs) were analyzed using JoinPoint Regression. Results: From 1999 to 2023, a total of 1,406,107 deaths related to cancer and hypertension were recorded in the United States. The AAMR increased from 12.59 in 1999 to 35.49 in 2023. Males had a higher mortality rate compared to women throughout the study period (AAMR; 30.3 vs. 20.4). Non-Hispanic (NH) Black Americans, or African Americans had the highest mortality rates, followed by NH white, Hispanic or Latino groups, and other NH groups. The highest AAMR was observed in the South, followed by the Midwest, the Northeast, and the West. Rural areas had higher mortality rates compared to urban areas. Conclusions: Cancer- and hypertension-related mortality rates have consistently increased in the United States from 1999 to 2023, particularly affecting males, NH Black Americans, the southern region, and rural areas. The trends highlight the need for targeted prevention, including early screening, lifestyle changes, and treatment adherence. Full article

Background: Assessing recent changes in mortality among patients undergoing hemodialysis (HD) can help both to identify the causes of death most closely associated with these changes and to develop prevention strategies. This study explored trends in all-cause and cause-specific mortality among patients undergoing HD in South Korea using an analysis of national data. Methods: We used national death certificate and claims data from 2003 to 2021 provided by the National Health Insurance Service. Age-standardized mortality rates (ASRs) were calculated by standardizing to the 2011 population of patients undergoing HD. Joinpoint regression analysis was performed to calculate the annual percentage change (APC) in mortality. All-cause and cause-specific ASRs and APCs were evaluated for the study period. Results: The proportion of male and older adult patients increased over time. In particular, the proportion of patients aged ≥ 80 years in the 2018–2021 period was more than 4 times higher than in the 2003–2007 period. From 2003 to 2021, there were a total of 136,302 deaths among patients undergoing HD in South Korea. Cardiovascular causes accounted for 13.6% of deaths, and the majority (86.4%) were attributed to noncardiovascular causes. In 2003, the all-cause ASR was 174.1 per 1000 person-years, which steadily decreased to 114.5 per 1000 person-years in 2021. The ASR from cardiovascular disease remained unchanged from 2003 to 2013 but increased by 3.9% (95% confidence interval: 1.3 to 14.0) per year from 2013 to 2021. In contrast, the ASR from noncardiovascular disease decreased during the study period. Conclusions: Nationally representative data showed a declining trend in the ASR among patients undergoing HD from 2003 to 2021. Noncardiovascular disease mortality decreased during the study period, while cardiovascular disease mortality increased. Full article

Background/Objectives: Identifying reliable biomarkers for healthy aging and longevity is a fundamental challenge in aging research and medical sciences. The neutrophil-to-lymphocyte ratio (NLR) is a readily measurable indicator of immune balance that reflects the interplay between innate immune activation and adaptive immune suppression. Methods: This study examined NLR values in 204 physically healthy residents (98 men and 106 women) stratified into four lifespan categories based on death certificates. Page’s test and ordinal regression (Cumulative Link Model) were used to assess trends with longevity. Results: In men, a downward trend in NLR values was observed. In women, a significant age-related decline in NLR was identified, with longer-lived individuals showing notably lower NLR values compared to their shorter-lived counterparts. The findings suggest that lower NLR is associated with longer survival, particularly in older women, reflecting superior immune regulation and reduced systemic inflammation. Conversely, elevated NLR may indicate immune dysfunction and heightened inflammatory burden. Conclusions: The results of this study complement existing findings, reinforcing the critical importance of immune balance in supporting healthy aging and longevity. These findings also underscore the potential of NLR as a robust biomarker for evaluating immune function and anticipating resilience to age-related decline, offering a practical tool for assessing immune health in the aging population.

Population-based cancer registries are crucial for tracking cancer trends, supporting research, guiding policy decisions, and ensuring efficient healthcare resource allocation. However, their effectiveness relies heavily on data quality, specifically the completeness of the cancer registration process. Background/Objectives: This systematic review aims to identify the methods used by adult population-based cancer registries worldwide to assess the completeness of their data. It also considered the significant role of high-quality data in method selection and the significant challenges of data handling. Methods: A comprehensive electronic literature search was conducted across the Web of Science, Scopus, and PubMed for studies published from January 2004 to December 2024. The review was written according to PRISMA guidelines, and the risk of bias was assessed using the Joanna Briggs Institute tool. Results: The review identified 83 studies from 31 countries, the majority from Europe, especially Nordic and Central European countries. Most studies met high-quality standards, with only one study scoring below 75%. Common approaches include independent case ascertainment (the most used), a capture–recapture analysis, a death-certificate-only analysis, and comparisons with historical rates. While independent case ascertainment is valuable when high-quality auxiliary sources are available, its accuracy varies. Other methods, like capture-recapture or Mortality-to-Incidence ratios, may be more accurate or feasible in some cases. Conclusions: The findings suggest that methods for completeness evaluations vary widely across registries, influenced by data quality and regional practices. The results emphasize the importance of the continuous refinement of these assessment methods to improve the reliability and global comparability of cancer registry data. Full article

Background/Objectives: Acute myocardial infarction (AMI) has been a leading cause of mortality in the US. Though AMI mortality has been decreasing in the US, significant disparities have persisted. We aim to evaluate disparities in AMI-related deaths in the US from 1999 to 2022. Methods: Data from the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research (CDC WONDER) multiple causes of death database were used to analyze death certificates from 1999 to 2022 for AMI-related deaths among United States older adults (aged ≥ 65) for overall trend and disparities based on demographic (sex, race/ethnicity, and ten-year age groups) and regional (census regions, rural-urban status, and states) subgroups. Rural and urban status were distinguished using definitions set by the 2013 NCHS Urban-Rural Classification scheme for counties. These data come from the 2010 Census report and are updated from the 2006 NCHS Urban-Rural Classification scheme for counties. The crude mortality rate (CMR) and age-adjusted mortality rates (AAMRs) per 100,000 people were used to calculate annual percentage changes (APCs) and average annual percentage changes (AAPCs) using Joinpoint regression analysis. Results: From 1999 to 2022, there were 3,249,542 deaths due to AMI. Overall, age-adjusted mortality rates (AAMRs) decreased by 62.78% from 563.2 * (95% CI 560.3–565.7) in 1999 to a nadir at 209.6 * (208.3–210.8) in 2019, with an AAPC of −4.96 * (95% CI −5.11 to −4.81). There were a total of 355,441 deaths from AMI from 2020 to 2022; 21,216 (5.97%) of those were from AMI with COVID-19 infection. An increase of 11.4% was observed from an AAMR of 209.6 * (95% CI 208.3–210.8) in 2019 to 233.5 * (95% CI 232.2–234.8) in 2021. From 2021 to 2022, the AAMR of AMI decreased from 233.5 * (95% CI 232.2–234.8) to 209.8 * (95% CI 208.6–211), recovering to the 2019 levels. The AAMR for AMI excluding associated COVID-19 infection was 217.2 at its peak in 2021, which correlates to only a 3.63% increase from 2019. Significant disparities in AMI mortality were observed, with higher mortality rates in men, African Americans, the oldest age group (age ≥ 85), and those living in southern states and rural areas. Conclusions: AMI mortality in the older adult population of the US has significantly decreased from 1999 to 2019, with a brief increase during the pandemic from 2019 to 2021, followed by recovery back to the 2019 level in 2022. The majority of the rise observed during the pandemic was associated with COVID-19 infection. Despite remarkable improvement in mortality, significant disparities have persisted, with men, African Americans, and those living in rural areas and the southern region of the US having disproportionately higher mortality.

Background and Objectives: Radon is a known risk factor for lung cancer, and residential radon exposure is the leading cause of lung cancer in never smokers; however, in Italy, there is still a lack of public awareness regarding the risk caused by residential radon exposure. In this mortality study, which was carried out in an Italian Apulian town (Locorotondo) of the Bari province, we aimed to analyze lung cancer mortality and all-cause mortality in a population highly exposed to radon. Materials and Methods: The study period was 1998–2021. Local and Italian population and national mortality data were collected from the Italian National Institute of Statistics (ISTAT) website platform. Local mortality data were collected using copies of the Local Health Authority death certificates. Results: We identified 117 lung cancers in the studied period. The mortality data trends revealed a decrease in the all-causes standardized mortality ratios (SMRs), increases in the incidence rates of lung cancer and colorectal cancer in recent years, and a decrease in the incidence of noncancer diseases. We also found high SMRs for colorectal cancer until 2016 among older females. With respect to the cardio-circulatory system, only in 2014 did the male SMRs significantly influence the total SMR; after this period, a decreasing stable trend was observed. Conclusions: The natural balance of the population is decreasing, and mortality is decreasing for all causes. A future study will be needed to assess the associations between observed lung cancer cases and domestic radon exposure to drive radon mitigation and public health strategies. Full article

Background and Objectives: The epidemiological data regarding mortality rates of adults with sarcoidosis and non-ischemic cardiovascular disease (CVD) are limited. A retrospective observational analysis was conducted to identify trends and disparities related to sarcoidosis and non-ischemic cardiovascular disease mortality among the adult US population from 1999 to 2022. Methods: We used the Centers for Disease Control and Prevention (CDC) WONDER database to extract death certificate data for the adult US population (≥25 years). The age-adjusted mortality rates (AAMRs) per 100,000 persons were calculated, and annual percent changes (APCs) were determined using Joinpoint. Results: Between 1999 and 2022, 23,642 deaths were identified related to non-ischemic CVD + sarcoidosis. The overall AAMR increased from 0.2 (95% CI, 0.2 to 0.3) in 1999 to 0.5 (95% CI, 0.5 to 0.6) in 2022. Females had a higher AAMR than males (0.6 vs. 0.5). Non-Hispanic (NH) blacks had the highest AAMR, followed by NH whites and Hispanic or Latinos. The southern region had the highest AAMR (0.7: 95% CI, 0.6–0.7), followed by the Midwest (0.6, 95% CI, 0.54–0.669), the Northeast (0.5, 95% CI, 0.5 to 0.6), and the West (0.4; 95% CI, 0.3–0.4). Urban and rural areas had comparable mortality rates (0.5 vs. 0.6). People aged 65+ had the highest AAMRs. Conclusions: The overall mortality rates for non-ischemic CVD and sarcoidosis have increased in the US from 1999 to 2022. Females and NH blacks had higher AAMRs, while a minimal variation was observed based on geographical regions. Early diagnosis and prompt management are the keys to reducing the mortality burden of non-ischemic CVD plus sarcoidosis. Full article

Multiple cause data refer to all conditions reported on death certificates. Compared to the single underlying cause of death, these data provide additional information concerning the presence of comorbidities and complications leading to death. The objective of the study is to use a novel multiple cause approach for identifying comorbidities and complications of COVID-19. We analysed certificates referring to deaths that occurred in Italy in 2020–2021. With a double step chi squared test, we identified the conditions associated with COVID-19 and whether such conditions were reported as ‘cause of’ (comorbidities) or ‘due to’ (complications) COVID-19. For comparison, we adopted the same procedure for influenza deaths that occurred in Italy in 2016–2019. Pneumonia, respiratory failure and adult respiratory distress syndrome are the most frequent complications of COVID-19 and are also associated with it. These diseases have the same role for influenza, nevertheless this latter is strongly associated also with heart failure reported as a complication. Comorbidities are similar for COVID-19 and influenza: diabetes mellitus, chronic obstructive pulmonary disease (COPD) and obesity are the most frequent, with obesity much more frequent in COVID-19 cases. Hypertension is strongly associated with COVID-19 and is more frequent than in influenza cases. This approach is also suitable for other target diseases. Full article

Ozone concentrations have increased in recent decades, and several studies have reported that long-term exposure to ozone increases the mortality risk induced by respiratory conditions. However, research on cause-specific mortality related to ozone exposure and respiratory diseases remains scarce. We constructed a retrospective cohort of 5,360,032 adults aged ≥ 65 years from the National Health Insurance Service of Republic of Korea, and death certificates were obtained from Statistics Republic of Korea to determine the cause of death between 2010 and 2019. The daily maximum 8 h average levels of ozone during the warm season annually (May–September) and other air pollutants were determined for the residential district. We analyzed the data using a time-varying Cox proportional hazards model with individual- and district-level covariates, incorporating a competing risk framework to address deaths from causes other than chronic obstructive pulmonary disease (COPD) and asthma. In our single-pollutant model with a 3-year moving average, a 1 ppb increase in ozone exposure was associated with a hazard ratio (HR) of 1.011 (95% confidence interval [CI]: 1.008–1.013) for COPD mortality and an HR of 1.016 (95% CI: 1.011–1.022) for asthma mortality. In our model adjusted for the presence of underlying diseases and district-level variables, the HRs were 1.009 (95% CI: 1.008–1.014) for COPD and 1.017 (95% CI: 1.011–1.023) for asthma, respectively. These associations remained robust in our two-pollutant model, except for NO₂ and COPD. A linear concentration–response relationship was identified between ozone concentration, COPD, and asthma mortality. In this large nationwide cohort study, long-term exposure to ozone was associated with an increased risk of death from COPD and asthma in older Korean adults. Full article

Background: The aim of this study was to analyze the association between center quality certifications and patients’ characteristics, clinical management, and outcomes after carotid revascularization. Methods: This study is a pre-planned sub-study of the ISAR-IQ project, which analyzes data from the Bavarian subset of the nationwide German statutory quality assurance carotid database. Hospitals were classified as to whether a certified vascular center (cVC) or a certified stroke unit (cSU) was present on-site or not. The primary outcome event was any stroke or death until discharge from the hospital. Results: In total, 31,793 cases were included between 2012 and 2018. The primary outcome rate in asymptomatic patients treated by CEA ranged from 0.7% to 1.5%, with the highest rate in hospitals with cVC but without cSU. The multivariable regression analysis revealed a significantly lower primary outcome rate in centers with cSU in asymptomatic patients (aOR 0.69; 95% CI 0.56–0.86; p < 0.001). In symptomatic patients needing emergency treatment, the on-site availability of a cSU was associated with a significantly lower primary outcome rate (aOR 0.56; 95% CI 0.40–0.80; p < 0.001), whereas the presence of a cVC was associated with higher risk (aOR 3.07; 95% CI 1.65–5.72). Conclusions: This study provides evidence of statistically significant better results in some sub-cohorts in certified centers. In centers with cSU, the risk of any stroke or death was significantly lower in asymptomatic patients receiving CEA or symptomatic patients treated by emergency CEA. Full article

Fusarium circinatum, the causative agent of pine pitch canker disease, is a pathogenic fungus that poses a significant threat to pine forests globally. It infects various Pinus species, causing resinous cankers, needle discoloration, and tree death. The disease severely impacts forest ecosystems, necessitating cost-effective and environmentally friendly management strategies. Contaminated pine seeds and seedlings are the main pathways for introducing this fungus to disease-free areas. To mitigate this disease and prevent its spread, it is crucial to implement new processes in forest plant production systems that align with the existing conditions of forest nurseries, ensuring effective and sustainable management. With this in mind, a national collaborative study involving 14 Portuguese partners was initiated to develop new prevention and mitigation strategies. In this work, four different treatments—MennoFlorades, Captan, ethanol, and hot water—were tested for their ability to eliminate F. circinatum from contaminated Pinus seeds in vitro. The most effective treatments were selected for further in vitro assays and real-context nursery germination trials to assess their impacts on seed germination, plant production, and certification. MennoFlorades, Captan, and hot water were tested in the nursery, with hot water showing the most promising results due to its negligible impact on seedlings, eco-friendly nature, ease of implementation, and cost-effectiveness. These findings offer promising prospects for preventing pine pitch canker outbreaks in nurseries and, consequently, in forests. Full article

The 11th Revision of the International Statistical Classification of Diseases, Injuries, and Causes of Death (ICD-11) will replace its predecessor as international standard for cause-of death-statistics. The digitization of healthcare is a main motivation for its introduction. In parallel, the replacement of the paper-based death certificate with an electronic format is under evaluation. At the moment, the death certificate is used in paper-based format with ICD-10 for coding in Germany. To be prepared for the switch to ICD-11, the compatibility between ICD-11 and the electronic certificate should be assured. Objectives were to check the appropriateness of diagnosis-related information found on death certificates for an ICD-11 coding and to describe enhancements to the certificate’s structure needed to fully utilize the strengths of ICD-11. As part of an exploratory test of a respective application, information from 453 electronic death certificates were provided by one local health authority. From a sample of 200 certificates, 433 diagnosis texts were coded into the German version of ICD-11. The appropriateness of the results as well as the further requirements of ICD-11, particularly with regard to post-coordination, were checked. For 430 diagnosis texts, 649 ICD-11 codes were used. Three hundred and sixty two diagnosis texts were rated as appropriately represented through the coding result. Almost all certificates contained diagnosis texts that lacked details required by ICD-11 for a precise coding. The distribution of diseases was very similar between ICD-10 and ICD-11 coding. A few gaps in ICD-11 were identified. Information requested by ICD-11 for a mandatory post-coordination were almost entirely absent from the death certificates. The structure and content of the death certificate are currently not well prepared for an ICD-11 coding. Necessary information was frequently missing. The line-oriented structure of death certificates has to be supplemented with a more flexible approach. Then, the semantic knowledge base of ICD-11 should better guide the content related input fields of a future electronic death certificate. Full article
