Adaptive Gaussian Markov random fields for child mortality estimation.

The under-5 mortality rate (U5MR), a critical health indicator, is typically estimated from household surveys in lower and middle income countries. Spatio-temporal disaggregation of household survey data can lead to highly variable estimates of U5MR, necessitating the usage of smoothing models which borrow information across space and time. The assumptions of common smoothing models may be unrealistic when certain time periods or regions are expected to have shocks in mortality relative to their neighbors, which can lead to oversmoothing of U5MR estimates. In this paper, we develop a spatial and temporal smoothing approach based on Gaussian Markov random field models which incorporate knowledge of these expected shocks in mortality. We demonstrate the potential for these models to improve upon alternatives not incorporating knowledge of expected shocks in a simulation study. We apply these models to estimate U5MR in Rwanda at the national level from 1985 to 2019, a time period which includes the Rwandan civil war and genocide.

Association of depressive symptoms with incidence and mortality rates of COVID-19 over 2 years among healthcare workers in 20 countries: multi-country serial cross-sectional study.

BACKGROUND: Long-term deterioration in the mental health of healthcare workers (HCWs) has been reported during and after the COVID-19 pandemic. Determining the impact of COVID-19 incidence and mortality rates on the mental health of HCWs is essential to prepare for potential new pandemics. This study aimed to investigate the association of COVID-19 incidence and mortality rates with depressive symptoms over 2 years among HCWs in 20 countries during and after the COVID-19 pandemic. METHODS: This was a multi-country serial cross-sectional study using data from the first and second survey waves of the COVID-19 HEalth caRe wOrkErS (HEROES) global study. The HEROES study prospectively collected data from HCWs at various health facilities. The target population included HCWs with both clinical and non-clinical roles. In most countries, healthcare centers were recruited based on convenience sampling. As an independent variable, daily COVID-19 incidence and mortality rates were calculated using confirmed cases and deaths reported by Johns Hopkins University. These rates represent the average for the 7 days preceding the participants' response date. The primary outcome was depressive symptoms, assessed by the Patient Health Questionnaire-9. A multilevel linear mixed model (LMM) was conducted to investigate the association of depressive symptoms with the average incidence and mortality rates. RESULTS: A total of 32,223 responses from the participants who responded to all measures used in this study on either the first or second survey, and on both the first and second surveys in 20 countries were included in the analysis. The mean age was 40.1 (SD = 11.1), and 23,619 responses (73.3%) were from females. The 9323 responses (28.9%) were nurses and 9119 (28.3%) were physicians. LMM showed that the incidence rate was significantly and positively associated with depressive symptoms (coefficient = 0.008, standard error 0.003, p = 0.003). The mortality rate was significantly and positively associated with depressive symptoms (coefficient = 0.049, se = 0.020, p = 0.017). CONCLUSIONS: This is the first study to show an association between COVID-19 incidence and mortality rates with depressive symptoms among HCWs during the first 2 years of the outbreak in multiple countries. This study's findings indicate that additional mental health support for HCWs was needed when the COVID-19 incidence and mortality rates increase during and after the early phase of the pandemic, and these findings may apply to future pandemics.

The burden of acute lymphoid leukemia among adolescents and young adults in the Western Pacific Region: evidence from Global Burden Disease 2019.

PURPOSE: Acute lymphoblastic leukemia (ALL) is a type of blood cancer that affects white blood cells. Here, we use data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, to estimate the burden and incidence rate changes in adolescents and young adults (AYA) ALL in the Western Pacific Region and to reveal potential risk factors of incidence- and mortality rates. METHODS: The GBD 2019 study data was stratified by sex, age, country, and territory. We calculated the Estimated annual percentage changes (estimated APC) in mortality and incidence rates for each of the 25 countries and territories of the western Pacific region from 1990 to 2019. RESULTS: This study found global AYA ALL incidence rates had increased while the mortality rates had decreased between 1990 and 2019. Moreover, healthcare access and quality (HAQ), and government per capita health spending were identified as country-level risk factors of AYA ALL incidence rates, while HAQ, male education, and sex were identified as mortality rate predictors in 25 Western Pacific Region countries. CONCLUSION: To address and reduce the burden of incidence and mortality among AYA, various regions around the world, particularly developing countries, could revise their AYA prevention and treatment strategies.

Comparison of Hospital Volume and Risk-Standardized Mortality Rate as a Proxy for Hospital Quality in Complex Oncologic Hepatopancreatobiliary Surgery.

BACKGROUND: Centralization of hepatopancreatobiliary procedures to more experienced centers has been recommended but remains controversial. Hospital volume and risk-stratified mortality rates (RSMR) are metrics for interhospital comparison. We compared facility operative volume with facility RSMR as a proxy for hospital quality. PATIENTS AND METHODS: Patients who underwent surgery for liver (LC), biliary tract (BTC), and pancreatic (PDAC) cancer were identified in the National Cancer Database (2004-2018). Hierarchical logistic regression was used to create facility-specific models for RSMR. Volume (high versus low) was determined by quintile. Performance (high versus low) was determined by RSMR tercile. Primary outcomes included median facility RSMR and RSMR distributions. Volume- and RSMR-based redistribution was simulated and compared for reductions in 90-day mortality. RESULTS: A total of 106,217 patients treated at 1282 facilities were included; 17,695 had LC, 23,075 had BTC, and 65,447 had PDAC. High-volume centers (HVC) had lower RSMR compared with medium-volume centers and low-volume centers for LC, BTC, and PDAC (all p < 0.001). High-performance centers (HPC) had lower RSMR compared with medium-performance centers and low-performance centers for LC, BTC, and PDAC (all p < 0.001). Volume-based redistribution required 16.0 patients for LC, 11.2 for BTC, and 14.9 for PDAC reassigned to 15, 22, and 20 centers, respectively, per life saved within each US census region. RSMR-based redistribution required 4.7 patients for LC, 4.2 for BTC, and 4.9 for PDAC reassigned to 316, 403, and 418 centers, respectively, per life saved within each US census region. CONCLUSIONS: HVC and HPC have the lowest overall and risk-standardized 90-day mortality after oncologic hepatopancreatobiliary procedures, but RSMR may outperform volume as a measure of hospital quality.

Hospitalization and mortality in Asian autoimmune bullous dermatosis patients: A 17-year retrospective study.

Limited data exist on the factors associated with hospitalization and mortality in Asian inpatients with autoimmune bullous dermatoses (AIBDs). This study aimed to elucidate the risk factors affecting hospitalization and mortality rates in Asian patients with AIBDs. A retrospective analysis of patients with AIBDs treated at Siriraj Hospital during a 17-year period was performed using the International Classification of Diseases 10th revision codes. The characteristics of inpatients and outpatients were compared, and mortality rates and associated factors were identified. The study included 360 AIBD patients (180 inpatients, 180 outpatients). Inpatients were significantly younger than outpatients. The identified risk factors for hospitalization were malignancy (odds ratio [OR] 2.83, 95% confidence interval [CI] 1.13-8.04; p = 0.034), moderate to severe disease (OR 2.52, 95% CI 1.49-4.34; p < 0.001), systemic corticosteroid use ≥15 mg/day (OR 2.27, 95% CI 1.21-4.41; p = 0.013) and oral cyclophosphamide treatment (OR 9.88, 95% CI 3.82-33.7; p < 0.001). Kaplan-Meier analysis revealed mortality rates of 26%, 36% and 39% for inpatients with pemphigus at 1, 3 and 5 years, respectively. For inpatients with pemphigoid, the corresponding rates were 28%, 38% and 47%. Infections, particularly pneumonia, were the predominant cause of death in both conditions. This study confirmed that both Asian ethnicity and healthcare disparities may be correlated with adverse outcomes in patients with AIBDs. Pemphigus mortality rates were substantially greater in Asian patients than in Caucasian patients. Continuous monitoring of factors contributing to hospitalization and mortality is imperative to improve treatment outcomes.

Cause-specific mortality in a population-level cohort of diffuse large B-cell lymphoma following chemotherapy in the early 21st century.

Diffuse large B-cell lymphoma (DLBCL) is a severe non-Hodgkin's lymphoma. Life expectancy has improved with rituximab, but cause-specific mortality data is lacking. Using the Surveillance, Epidemiology, and End Results (SEER) database to study 27,449 individuals aged 20-74 years diagnosed with primary DLBCL who received chemotherapy between 2000 and 2019, we calculated standardized mortality rate (SMR) and excess absolute risk (EAR) and examined the connection between age, sex, time after diagnosis, and cause of death. Based on 12,205 deaths, 68.7% were due to lymphoma, 20.1% non-cancer causes, and 11.2% other cancers. Non-cancer mortality rates (SMR 1.2; EAR, 21.5) increased with DLBCL compared to the general population. The leading non-cancer death causes were cardiovascular (EAR, 22.6; SMR, 1.6) and infectious (EAR, 9.0; SMR, 2.9) diseases with DLBCL. Risks for non-cancer death and solid neoplasms are highest within the first diagnosis year, then decrease. Among socioeconomic factors, being white, being married, and having a higher income were favorable factors for reducing non-cancer mortality. To improve survival, close surveillance, assessment of risk factors, and early intervention are needed.

Trends in multiple myeloma incidence, prevalence, mortality, and survival rate in South Korea: a nationwide population-based study.

This is the first study presenting the overall descriptive epidemiology of multiple myeloma (MM), including incidence, mortality rate, and prevalence, in South Korea between 2010 and 2018 based on nationwide medical insurance coverage and mortality statistics data. The incidence of MM between 2010 and 2018 was obtained from nationwide medical claims data, and mortality data were obtained from the Korea National Statistical Office. The age-standardized incidence rate (ASIR) and mortality rate (ASMR) and one- and five-year survival rates of patients with MM each year were estimated. There were 10,835 patients with MM aged ≥ 20 years in South Korea between 2010 and 2018. The ASIR was 2.42/100,000 in 2010 and increased to 2.71/100,000 in 2018, with an annual percent change (APC) of 1.86% (95% CI = 0.74-2.99%, P = 0.005). While this trend was significant in women, it was not statistically significant in men. The ASMR did not significantly change over time. Furthermore, the median survival time of patients with MM diagnosed between 2010 and 2018 was 3.36 years. Notably, the one-year survival rate of patients was increased from 65.3% in 2010 to 76.2% in 2017. Finally, the proportion of patients with MM who received novel therapeutic agents, such as proteasome inhibitors or immunomodulatory drugs, as first-line treatment increased from 37.7% in 2010 to 97.8% in 2018. The ASIR and prevalence of MM in South Korea increased between 2010 and 2018, especially in women and the survival rate of patients with MM has increased.

Sex Differences in Mortality Risk after the First Hospitalisation with Lower Extremity Peripheral Arterial Disease.

OBJECTIVE: Lower extremity peripheral arterial disease (PAD) is a severe condition that increases the risk of major adverse cardiovascular events, major adverse limb events, and all cause mortality. This study aimed to investigate the mortality risk among females and males hospitalised for the first time with lower extremity PAD. METHODS: Three cohorts of patients who were admitted for the first time with lower extremity PAD in 2007 - 2010, 2011 - 2014, and 2015 - 2018 were constructed. For the 2007 - 2010 and 2011 - 2014 cohorts, the 28 day, one year, and five year mortality rates were calculated, assessing survival time from date of hospital admission until date of death, end of study period, or censoring. For the 2015 - 2018 cohort, only 28 day and one year mortality were investigated due to lack of follow up data. Mortality rates of these cohorts were compared with the general population using standardised mortality rates (SMRs), and the risk of death between sexes was evaluated using Cox proportional hazards models. Cox models were adjusted for age, cardiovascular disease, and diabetes mellitus to account for potential confounding factors. RESULTS: In total, 7 950, 9 670, and 13 522 patients were included in the 2007 - 2010, 2011 - 2014, and 2015 - 2018 cohorts, respectively. Over 60% of individuals in each cohort were males. Mortality rates at 28 day and one year remained stable across all cohorts, while the five year mortality rate increased for both males and females in the 2011 - 2014 cohort. The SMRs both of females and males with PAD were significantly higher than in the general population. Multivariable regression analyses found no significant differences in mortality risk between sexes at 28 day and one year. However, the five year mortality risk was lower in females, with a hazard ratio of 0.89 (95% confidence interval [CI] 0.83 - 0.97) in the 2007 - 2010 cohort and 0.88 (95% CI 0.82 - 0.94) in the 2011 - 2014 cohort. CONCLUSION: The five year mortality risk has increased, and females face a lower mortality risk than males. Lower extremity PAD still carries unfavourable long term consequences compared with the general population.

Estimation of mortality rate ratios for chronic conditions with misclassification of disease status at death.

Estimation of mortality rates and mortality rate ratios (MRR) of diseased and non-diseased individuals is a core metric of disease impact used in chronic disease epidemiology. Estimation of mortality rates is often conducted through retrospective linkage of information from nationwide surveys such as the National Health Interview Survey (NHIS) and death registries. These surveys usually collect information on disease status during only one study visit. This infrequency leads to missing disease information (with right censored survival times) for deceased individuals who were disease-free at study participation, and a possibly biased estimation of the MRR because of possible undetected disease onset after study participation. This occurrence is called "misclassification of disease status at death (MicDaD)" and it is a potentially common source of bias in epidemiologic studies. In this study, we conducted a simulation analysis with a high and a low incidence setting to assess the extent of MicDaD-bias in the estimated mortality. For the simulated populations, MRR for diseased and non-diseased individuals with and without MicDaD were calculated and compared. Magnitude of MicDaD-bias depends on and is driven by the incidence of the chronic disease under consideration; our analysis revealed a noticeable shift towards underestimation for high incidences when MicDaD is present. Impact of MicDaD was smaller for lower incidence (but associated with greater uncertainty in the estimation of MRR in general). Further research can consider the amount of missing information and potential influencers such as duration and risk factors of the disease.

Evaluating neonatal mortality in Malta compared with other EU countries: Exploring the influence of congenital anomalies and maternal risk factors.

BACKGROUND: Globally, 240,000 babies die in the neonatal period annually due to congenital anomalies (CA). Malta reports the highest neonatal mortality rate (NMR) among EU (European Union) Countries, constituting a public health concern. OBJECTIVES: This study describes the contribution of CA to NMR in Malta, investigating possible associations with known maternal risk factors of maternal age, nationality, and education. Additionally, it provides an update on the contribution of CA to neonatal deaths in Malta and other EU countries. METHODS: Anonymous data for births and neonatal deaths were obtained for 2006-2020 from the National Obstetrics Information System (NOIS) in Malta. Regression analyses adjusting for maternal risk factors were run on this data to explore possible associations with NMR. NMRs published by EUROSTAT 2011-2020 were used to compare mortality by underlying cause of death (CA or non-CA causes) for Malta and other EU countries. RESULTS: Between 2006 and 2020, 63,890 live births with 283 neonatal deaths were registered in Malta, (NMR 4.4 per 1000 live births). CA accounted for 39.6% of neonatal deaths. No time trends were observed in either total NMR, NMR attributed to CA or mortality due to non-CA causes. Adjusted variables revealed associations for women hailing from non-EU, low-income countries. Malta registered high NMRs compared to EU countries, most marked for deaths attributed to CA. CONCLUSIONS: Between 2006 and 2020, Malta's NMR remained stable. Maternal Nationality, from non-EU low-income countries, was associated with higher neonatal mortality. The influx of such migrants may play a partial role in the high NMRs experienced. Malta's high NMR was primarily driven by early neonatal deaths, which included high proportions of deaths due to CA and is linked to the fact that termination of pregnancy is illegal in Malta.

COVID-19 increases mortality in hemodialysis patients: exploring links with inflammation and telomere attrition.

BACKGROUND AND OBJECTIVE: An increased risk of mortality and hospitalization was consistently demonstrated in hemodialysis (HD) patients affected by pandemic coronavirus infection (COVID-19). In this study, we analyzed parameters that may impact mortality in COVID-19 HD patients, including neutrophil-to-lymphocyte ratio (NLR), lactate dehydrogenase (LDH), C-reactive protein (CRP), COVID-19 disease status and telomere length in peripheral blood cells (TL). MATERIALS AND METHODS: A total of 130 chronic hemodialysis patients were enrolled and followed up for 18 months. Patients were categorized into groups based on their COVID-19 disease history and subsequent data about their survival status at the end of the study. Routine laboratory parameters were assessed using standard automated methods and TL was determined using the modified Cawthon method. Survival predictors were analyzed using Kaplan-Meier analysis. RESULTS: Deceased patients (30%) were older with higher body mass index (BMI), higher levels of LDH, NLR index, CRP and lower TL and lymphocytes count compared to survivors. Kaplan-Meier survival analysis showed six parameters were significant mortality predictors in the following order of significance: COVID-19 history, 2-years cardiovascular mortality risk score, NLR, TL, CRP, LDH. Using binary logistic regression analysis Summary risk score, a combination of these six parameters revealed as the best predictor of patient's survival in this group of parameters (log rank 25.4, p < 0.001). CONCLUSION: Compared to the general population, the mortality rate among HD patients persists at a higher level despite advancements in HD technology and patient care. The situation has been exacerbated by COVID-19, by significant increase in mortality rate among these patients.

Late-onset sepsis in newborns caused by Bacillus Cereus: a case report and literature review.

Bacillus cereus is a bacterium capable of causing late-onset neonatal sepsis. By analyzing 11 cases, this study investigates the diagnosis, treatment, and prognosis of Bacillus cereus infections, aiming to provide insights into clinical diagnosis and therapy. The study scrutinized 11 instances of late-onset neonatal sepsis, including two fatalities attributable to Bacillus cereus, one accompanied by cerebral hemorrhage. An examination and analysis of these cases' symptoms, signs, laboratory tests, and treatment processes, along with a review of related literature from 2010 to 2020, revealed a high mortality rate of 41.38% in non-gastrointestinal infections caused by Bacillus cereus. Our findings underscore the critical importance of rapid diagnosis and effective antimicrobial therapy in reducing mortality rates. Once the source of infection is identified, implementing effective infection control measures is essential.

Changes in mortality during the COVID-19 pandemic in Japan: descriptive analysis of national health statistics up to 2022.

BACKGROUND: Amidst the global coronavirus disease (COVID-19) pandemic, Japan has faced a significant public health challenge, evident from the significant increase in mortality rates since 2021. This study described the variations in all-cause and cause-specific changes in mortality up to 2022 in Japan. METHODS: This study used official Vital Statistics from the Ministry of Health, Labour and Welfare (MHLW) to assess the impact of the pandemic on mortality trends. An analysis of all-cause and cause-specific age-standardized mortality rates (ASMRs) from 1995 to 2022 was conducted, employing the 2015 Japan Standard Population. Sex- and cause-specific ASMRs for a particular year were compared with those from the preceding year to assess annual changes. RESULTS: Among men, the annual all-cause ASMR per 100,000 people increased from 1356.3 in 2021 to 1437.8 in 2022 (6.0% increase). Among women, the annual all-cause ASMR increased from 722.1 in 2021 to 785.8 in 2022 (6.5% increase). Compared with the period 2020 to 2021, COVID-19 (+29.1 per 100,000 people for men and +13.4 per 100,000 people for women), senility (+14.1 per 100,000 people for men and +12.5 per 100,000 people for women), heart disease, malignant neoplasms (for women) and "other causes not classified as major causes" substantially contributed to the increase in all-cause ASMR from 2021 to 2022. CONCLUSIONS: Further long-term monitoring from 2023 onwards is necessary, especially for conditions like senility, cardiovascular disease, and cancer, which may have long-term effects due to changes in healthcare settings, even though the strong countermeasures against COVID-19 were lifted in 2023.

Spatiotemporal trends in the burden of aortic aneurysms caused by high sodium intake from 1990 to 2019: A global, regional, and national analysis.

BACKGROUND AND AIMS: This study, drawing on Global Burden of Disease (GBD) data, examines spatiotemporal trends in mortality and disability-adjusted life years (DALYs) linked to aortic aneurysm (AA) from high sodium intake. The aim is a comprehensive analysis globally, regionally, and nationally spanning 1990 to 2019. METHODS AND RESULTS: Quantifying AA deaths and DALYs due to high sodium intake, incorporating age-standardized mortality rate (ASMR) and age-standardized DALYs rate (ASDR), revealed a global surge. Deaths rose by 86.09 %, DALYs by 74.02 % from 1990 to 2019. EAPC for ASMR and ASDR displayed negative trends (-0.72 and -0.77). High/middle-high Socio-demographic Index (SDI) regions bore higher burdens than lower SDI regions. Males consistently had higher burdens across SDI regions, with both genders showing a slight downward trend. Age-wise, AA deaths and DALYs rose with age, followed by decline. A positive correlation existed between SDI and global burden, inversely related to EAPC for ASMR and ASDR. CONCLUSION: AA burden from high sodium intake is pronounced in high SDI regions, necessitating targeted interventions. The global data highlights a significant increase in AA deaths and DALYs due to high sodium intake, urging prompt and effective control measures.

Association between maternal health service utilization and under-five mortality rate in China and its provinces, 1990-2017.

BACKGROUND: The United Nations (UN) Sustainable Development Goal - 3.2 aims to eliminate all preventable under-five mortality rate (U5MR). In China, government have made efforts to provide maternal health services and reduce U5MR. Hence, we aimed to explore maternal health service utilization in relation to U5MR in China and its provinces in 1990-2017. METHODS: We obtained data from Global Burden of Disease 2017, China Health Statistics Yearbook, China Statistical Yearbook, and Human Development Report China Special Edition. The trend of U5MR in each province of China from 1990 to 2017 was analyzed using Joinpoint Regression model. We measured the inequities in maternal health services using HEAT Plus, a health inequity measurement tool developed by the UN. The generalized estimating equation model was used to explore the association between maternal health service utilization (including prenatal screening, hospital delivery and postpartum visits) and U5MR. RESULTS: First, in China, the U5MR per 1000 live births decreased from 50 in 1990 to 12 in 2017 and the average annual percentage change (AAPC) was - 5.2 (p < 0.05). Secondly, China had a high maternal health service utilization in 2017, with 96.5% for prenatal visits, 99.9% for hospital delivery, and 94% for postnatal visits. Inequity in maternal health services between provinces is declining, with hospital delivery rate showing the greatest decrease (SII, 14.01 to 1.87, 2010 to 2017). Third, an increase in the rate of hospital delivery rate can significantly reduce U5MR (OR 0.991, 95%CI 0.987 to 0.995). Postpartum visits rate with a one-year lag can reduce U5MR (OR 0.993, 95%CI 0.987 to 0.999). However, prenatal screening rate did not have a significant effect on U5MR. CONCLUSION: The decline in U5MR in China was associated with hospital delivery and postpartum visits. The design and implementation of maternal health services may provide references to other low-income and middle-income countries.

Perinatal death in the Nordic countries in relation to gestational age: The impact of registration practice.

INTRODUCTION: Although perinatal death rates in the Nordic countries are among the lowest in the world, the risk of perinatal death is unevenly distributed across the Nordic countries, despite similarity in health care systems and pregnancy care. Birth registration practices across countries may explain some of the differences. We investigated differences in national registration of perinatal mortality within the Nordic countries and its impact on perinatal mortality according to gestational age. MATERIAL AND METHODS: Each country provided information by answering a questionnaire about registration of perinatal deaths. Furthermore, we collected aggregated count data based on Medical Birth Registries (MBR) from all Nordic countries in 2000 to 2021. Perinatal mortality was defined as stillbirth or neonatal death occurring within first 7 days of life. Data were grouped into six groups by gestational age (GA): extremely preterm (>28 + 0 weeks, subdivided into 22 + 0-23 + 6 and 24 + 0-27 + 6), very preterm (GA 28 + 0-31 + 6), moderate preterm (GA 32 + 0-33 + 6), late preterm (GA 34 + 0-36 + 6), term (GA 37 + 0-40 + 6) and late term or post-term birth (GA ≥ 41 + 0). Perinatal mortality rate and risk ratio with 95% confidence intervals were calculated per country for each gestational age group. For Denmark, separate analyses included and excluded induced abortions. RESULTS: The study included 6 343 805 live births, 22 727 stillbirths and 8932 liveborn infants who died within the first week of life after GA 22 + 0. Further 25 057 births were included with GA < 22 + 0, unknown GA and as a result of induced abortion. Overall, perinatal mortality rates decreased during year 2000-2021 in all Nordic countries. After exclusion of induced abortions, the perinatal mortality rate was similar in the five Nordic countries. The perinatal mortality rate for extremely preterm born infants was highest in Denmark, whereas the highest rate among infants born late term/post-term was in Sweden. CONCLUSIONS: The perinatal mortality rate in the Nordic countries is still decreasing, especially in the group of extremely preterm born infants. This study supports the need for further standardization of birth registration practices to ensure the validity of international comparisons.

Epidemiology and management of transient ischemic attack in Trieste district, how day hospital assessment improves outcomes: a five-year retrospective study.

BACKGROUND: Transient ischemic attack (TIA) is defined as a transient episode of neurologic dysfunction, without acute infarction or tissue injury lasting less than 24 h. Previous data suggest TIA precedes 15% of ischemic strokes, with a higher risk in the first week. Current practice guidelines advise evaluation through rapid neurological visit or admission to hospital. We provide data on TIA incidence in Trieste, and we compare three different types of assessment: day hospital (DH), stroke unit (SU), and emergency department/outpatients (ED). METHODS: This is a 5-year retrospective study of transient cerebrovascular events admitted in the University Hospital of Trieste (230.623 inhabitants), between 2016 and 2020. We calculated TIA prevalence in Trieste district's general population. Our primary endpoint is ischemic recurrences within 90 days, and we evaluate the possible association between different types of management. RESULTS: TIA incidence rate was 0.54/1000 inhabitants. In the multivariate analysis remained significantly associated with primary endpoint: ABCD2 (OR 1.625, CI 95% 1.114-2.369, p = 0.012) and DH evaluation (OR 0.260, CI 95% 0.082-0.819, p = 0.021). CONCLUSIONS: Incidence of TIA in Trieste district is in line with previous data. We demonstrate the crucial role of DH evaluation over the outpatient/ED in reducing overall mortality and recurrence rate. Prompt recognition of patients at high risk for cerebrovascular events and specialist follow-up may reduce the incidence of major vascular events and death.

Negative excess oral and pharyngeal cancer mortality in Europe during the early pandemic years.

OBJECTIVE: The COVID-19 pandemic had direct and indirect effects on oral and pharyngeal cancer (OPC) mortality due to high COVID-19 mortality risk among cancer patients, and to the COVID-19 response that caused treatment delays and reduced routine visits. This study investigated the excess OPC mortality in Europe during the early pandemic years. METHODS: Mortality and population data were gathered from the Eurostat database. The 2011-2019 mortality rates were used to estimate the 2020-2021 expected rates through joinpoint trend analysis. The excess mortality rates (observed minus expected mortality) with 95% confidence intervals (95 CIs) were assessed. RESULTS: Statistically significant negative excess age-standardized and crude (age strata <65 and ≥65 years) OPC mortality rates in males and females, in the European Union (EU, 27 countries) and Europe were reported. The estimated OPC missing deaths in EU were 831 (95 CI, 630-985) and 1240 (95 CI, 1039-1394) in 2020 and 2021, respectively, with differences between sexes, age strata, and countries. The OPC deaths in the EU and Europe were 3.6% and 3.5% lower than expected. CONCLUSION: Missing OPC deaths reported in Europe in 2020-2021 could be explained by changes in death certification of OPC patients who developed COVID-19, rather than a real OPC mortality decline.

Clinical characteristics of patients hospitalized for COVID-19: comparison between different age groups.

BACKGROUND: To test whether known prognosticators of COVID-19 maintained their stratification ability across age groups. METHODS: We performed a retrospective study. We included all patients (n = 2225), who presented to the Emergency Department of the Careggi University Hospital for COVID-19 in the period February 2020-May 2021, and were admitted to the hospital. The following parameters were analyzed as dichotomized: 1) SpO2/FiO2 ≤ or > 214; 2) creatinine < or ≥ 1.1 mg/dL; 3) Lactic dehydrogenase (LDH) < or ≥ 250 U/mL; 4) C Reactive Protein (CRP) < or ≥ 60 mg/100 mL. We divided the study population in four subgroups, based on the quartiles of distribution of age (G1 18-57 years, G2 57-71 years, G3 72-81 years, G4 > 82). The primary end-point was in-hospital mortality. RESULTS: By the univariate analysis, the aforementioned dichotomized variables demonstrated a significant association with in-hospital mortality in all subgroups. We introduced them in a multivariate model: in G1 SpO2/FiO2 ≤ 214 (Relative Risk, RR 15.66; 95%CI 3.98-61,74), in G2 creatinine ≥ 1.1 mg/L (RR 2.87, 95%CI 1.30-6.32) and LDH ≥ 250 UI/L (RR 8.71, 95%CI 1,15-65,70), in G3 creatinine ≥ 1.1 mg/L (RR 1.98, 95%CI 1,17-3.36) and CRP ≥ 60 ng/L (RR 2.14, 95%CI 1.23-3.71), in G4 SpO2/FiO2 ≤ 214 (RR 5.15, 95%CI 2.35-11.29), creatinine ≥ 1.1 mg/L (RR 1.75, 95%CI 1.09-2.80) and CRP ≥ 60 ng/L (RR 1.82, 95%CI 1.11-2.98) were independently associated with an increased in-hospital mortality. CONCLUSIONS: A mild to moderate respiratory failure showed an independent association with an increased mortality rate only in youngest and oldest patients, while kidney disease maintained a prognostic role regardless of age.

Rhabdomyolysis in older adults: outcomes and prognostic factors.

BACKGROUND: Rhabdomyolysis is a common condition in older adults, often associated with falls. However, prognostic factors for rhabdomyolysis have mainly been studied in middle-aged populations. OBJECTIVE: To test the hypothesis that age influences rhabdomyolysis prognostic factors. METHODS: This retrospective single-center observational study included all patients with a creatine kinase (CK) level greater than five times normal, admitted to Rennes University Hospital between 2013 and 2019. The primary endpoint was 30-day in-hospital mortality rate. RESULTS: 343 patients were included (median age: 75 years). The mean peak CK was 21,825 IU/L. Acute renal failure occurred in 57.7% of the cases. For patients aged 70 years and over, the main etiology was prolonged immobilization after a fall. The 30-day in-hospital mortality rate was 10.5% (23 deaths). The Charlson score, number of medications and CK and creatinine levels varied according to age. Multivariate analysis showed age to be a factor that was associated, although not proportionally, with 30-day in-hospital mortality. CONCLUSION: Factors influencing rhabdomyolysis severity were not randomly distributed according to age. The term rhabdomyolysis encompasses various clinical realities and is associated with different mechanisms. More research is needed to better understand the physio-pathological and prognostic factors of rhabdomyolysis, especially in older adults.
