Mortality Status Research Articles

Global, regional, and national temporal trends of diet-related ischemic stroke mortality and disability from 1990 to 2019.

Stroke is the second leading cause of death and the third leading cause of disability in the general population worldwide. However, the changing trend of ischemic stroke burden attributable to various dietary risk factors has not been fully revealed and may contribute to a better understanding of stroke epidemiology. Our article aimed to evaluate the temporal trend of diet-related ischemic stroke burden to inform future research and policy-making. This analysis was based on the data from the Global Burden of Disease (GBD) Study 2019 (spanning years 1990 to 2019), and we used the joinpoint regression to model temporal trends in diet-related ischemic stroke burden across countries and regions of the world during the study period. Six specific dietary factors known to influence stroke risk, including sodium, red meat, fiber, vegetables, whole grains, and fruits, were evaluated in the GBD study to determine their individual and joint impact on ischemic stroke. The changing trend was primarily measured by the average annual percent change (AAPC). Age-standardized rates (ASRs) of mortality and years lived with disability (YLD) per 100,000 population were used to evaluate disease burden. Finally, the socioeconomic background, which was quantified as sociodemographic index (SDI), and its association with diet-related ischemic stroke burden were also explored with the Pearson correlation coefficient. During the study period, the ischemic stroke ASR of mortality attributable to overall dietary risk decreased by an average of 1.6% per year, while the ASR of YLD decreased by an average of 0.2% per year. High sodium diet was still a key driver of diet-related ischemic stroke, accounting for 8.4% and 11.0% of deaths and disabilities, respectively, in 2019. In addition, we found a negative association between temporal evolution of stroke burden and socioeconomic background (r = -0.6603 for mortality and r = -0.4224 for disability, P < 0.001), which suggested that the developing countries with weak social and economic foundation faced greater challenges from the ongoing burden of diet-related strokes compared with developed countries. Our study found declining trends and revealed the current status of diet-related ischemic stroke mortality and disability. Interdisciplinary countermeasures involving the development of effective food policies, evidence-based guidelines, and public education are needed in the future to combat this global epidemic. The data used for analysis were open-access and can be obtained from https://vizhub.healthdata.org/gbd-results/.

Mortality among non-severely under nourished children with pneumonia globally: protocol for a systematic review and meta-analysis

Background Pneumonia remains the commonest cause of ill health and mortality among children worldwide. Severe undernutrition increases the mortality risk among children with pneumonia. While children with pneumonia are at increased risk of developing malnutrition, the impact of pneumonia on mortality and nutritional status of non-severely undernourished children is not well described. The impact of nutritional supplementation on mortality and nutritional status in this population is not well understood. This review will collate available evidence on the all-cause mortality and anthropometric indices outcomes following pneumonia, as well as the impact of nutritional supplementation on mortality and anthropometry among non-severely malnourished children with pneumonia. Methods The review will be done using a priori criteria developed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. Data will be obtained from data bases, grey literature, and bibliographies. An experienced librarian will conduct article search in PUBMED, MEDLINE, EMBASE, Web of Science, Google scholar, and Scopus. Retrieved articles will be entered in Endnote ver 9.0, duplicates removed, and transferred to Epi-reviewer for screening and data abstraction. Risk of bias in the included articles will be assessed using standard criteria. Heterogeneity will be assessed using I2-statistic and sub-group analysis will be done. Data will be analysed using both narrative and quantitative synthesis. Quantitative synthesis will be done using DeSimonian and Laird Random-effects model in STATA ver 15.0. Conclusions The results will provide baseline information about the mortality and anthropometric outcomes of pneumonia among non-severely malnourished children as well as the potential effect of nutritional supplementation on these outcomes. This will provide a basis to explore the potential for nutritional supplementation improving clinical outcomes like mortality and occurrence of severe acute malnutrition among children with severe pneumonia worldwide. Registration The review has been registered in PROSPERO (CRD42021257272; 15 July 2021).

Associations of Lower-Carbohydrate and Lower-Fat Diets with Mortality among People with Cardiovascular Disease

BackgroundAlthough low-carbohydrate and low-fat diets have been shown to have short-term metabolic benefits, the associations of these dietary patterns, particularly different food sources and macronutrient quality, with mortality in people with cardiovascular disease (CVD) remain unclear. ObjectivesTo examine the associations of different types of lower-carbohydrate diets (LCDs) and lower-fat diets (LFDs) with mortality in individuals with CVD. MethodsThis study included 3971 adults with CVD from the NHANES 1999–2014. Mortality status was linked to National Death Index mortality data through 31 December 2019. Overall, unhealthy and healthy LCD and LFD scores were determined based on the percentages of energy from total and subtypes of carbohydrate, fat, and protein. Cox proportional hazards regression models were applied to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). ResultsHigher healthy LCD score was associated with favorable blood lipids and higher homeostasis model assessment of insulin resistance, whereas higher unhealthy LFD score was associated with lower high-density lipoprotein and higher C-reactive protein at baseline (all P-trend < 0.05). During 35,150 person-years of follow-up, 2163 deaths occurred. For per 20-percentile increment in dietary scores, the multivariate-adjusted HRs of all-cause mortality were 0.91 (95% CI: 0.86, 0.96) for healthy LCD score (P < 0.001), 0.94 (95% CI: 0.89, 1.00) for healthy LFD score (P = 0.04), and 1.07 (95% CI: 1.00, 1.14) for unhealthy LFD score (P = 0.04). ConclusionsOverall LCD and LFD scores are not associated with total mortality. Unhealthy LFD scores are associated with higher total mortality, whereas healthy LCD and LFD scores are associated with lower mortality in people with CVD.

Time to death and its determinants of under-five children in rural Ethiopia by using shared frailty

Under-five (U5M) is one of the most significant and sensitive measures of the community's health. Children who live in rural areas are more likely than those who live in urban areas to die before the age of five. Therefore, the study aimed to assess the Survival status of under-five mortality and its determinants in rural Ethiopia. The 2019 Ethiopia Mini Demographic and Health Survey was used in this study as a secondary source (EMDHS). A total of 4426 weighted under-five children were included in the study. To determine survival time and identify predictors of death among children under the age of five, the Cox's gamma shared frailty model and the Kaplan Meier model, respectively, were used. An adjusted Hazard Ratio (AHR) along with a 95% Confidence Interval (CI) were used to measure the size and direction of the association. The Study showed that in rural Ethiopia, 6.03% of children died before celebrating their first birthday. The median age of under-five mortality in rural Ethiopia was estimated to be 29 Months. The hazard of death among under-five children and those who had given birth to two children in the last five years was 4.99 times less likely to be at risk of dying than those who had given birth to one Child in the previous five years (AHR 4.99, 95% CI 2.97, 8.83). The Study Concluded that under-five mortality remained high in rural Ethiopia. In the final model, the Age of Mothers, Sex of Household, Breastfeeding, Types of Birth, Sex of Child, Educational Level of Mothers, Wealth Index, Child ever born, Marital Status, and Water Source were significant predictors of under-five mortality. Twins and children who are not breastfed should receive additional attention, along with improving water resources for households and mothers income.

The impact of COVID-19 and vaccination status on outcomes in veterans with head and neck squamous cell carcinoma.

The impact of both COVID-19 infection and vaccination status on patients with head and neck squamous cell carcinoma (HNSCC) remains unknown. To determine the impact of COVID-19 infection and vaccination status on 60-day mortality, cardiovascular, and respiratory complications in patients with a prior diagnosis of HNSCC. This was a retrospective cohort study through the Veterans Affairs (VA) Corporate Data Warehouse of Veterans with HNSCC who were tested for COVID-19 during any inpatient VA medical center admission. A cohort of patients was created of Veterans with a diagnosis of HNSCC of the oral cavity,oropharynx, hypopharynx, larynx, and nasopharynx based on International Classification of Disease (ICD) codes. Data collected included clinical/demographic data, vaccination status, and incidence of 60-day mortality, 60-day cardiovascular complication (including myocardial infarction, venous thromboembolism, cerebrovascular accident), and 60-day respiratory complication (including acute respiratory failure, acute respiratory distress syndrome, and pneumonia). The interactions between COVID-19 infection, vaccination status, morbidity and mortality were investigated. Of the 14 262 patients with HNSCC who were tested for COVID-19 during inpatient admission, 4754 tested positive (33.3%), and 9508 (67.7%) tested negative. Patients who tested positive demonstrated increased 60-day mortality (4.7% vs. 2.0%, respectively; p < 0.001), acute respiratory failure (ARF; 15.4% vs. 7.1%, p < 0.001), acute respiratory distress syndrome (ARDS; 0.9% vs. 0.2%, p < 0.001), and pneumonia (PNA; 20.0% vs. 6.4%, p < 0.001) compared to those who never tested positive, respectively. Patients who received COVID-19 vaccination between 2 weeks and 6 months prior to a positive test demonstrated decreased rates of ARF (13.2% vs. 16.0%, p = 0.034) and PNA (16.7% vs. 20.9%, p = 0.003) compared to the unvaccinated group. A logistic regression of patients with COVID-19 infections who died within 60 days was performed, with no significant survival advantage among patients vaccinated between 2 weeks and 6 months prior to the positive test. COVID-19 infection may significantly increase rates of 60-day mortality and respiratory complications in patients with HNSCC. COVID-19 vaccination between 2 weeks and 6 months prior to infection may decrease severity of respiratory complications but did not show significant mortality benefits in this study. These data highlight the need for surveillance of respiratory infection and vaccination in this vulnerable population.

Association of neutrophil-to-lymphocyte ratio and risk of cardiovascular and all-cause mortality in hypertension patients

Background and objectiveHypertension affects over a billion people worldwide and is often associated with poor prognoses. The neutrophil-to-lymphocyte ratio (NLR) has become a significant marker, showing a connection to adverse outcomes in cardiovascular diseases (CVDs). The objective of this study is to examine the relationship between the NLR and outcomes in patients with hypertension. MethodsThe study included hypertensive individuals who were surveyed in the National Health and Nutrition Examination Survey (NHANES) from 2009 to 2018. Mortality status was determined using the data from National Death Index (NDI). To investigate the dose-response relationship, restricted cubic spline (RCS) models were used. This study employed adjusted cox proportional hazards regression models to compute hazard ratios (HRs) and their corresponding 95% confidence intervals (CIs) for all-cause and cardiovascular mortality. The predictive accuracy of the NLR for survival outcomes was assessed utilizing time-dependent receiver operating characteristic (ROC) curve analysis. ResultsA total of 13,724 participants were included in the final analysis, including 7073 males and 6651 females. The cohort was stratified into higher (>2.0) and lower (≤2.0) NLR groups according to the median value. Over a median follow-up of 64 months, there were 1619 all-cause deaths and 522 cardiovascular deaths among participants. The RCS analysis indicated a non-linear relationship between NLR and the risk of mortality. The adjusted model showed that the group with a higher NLR had a significantly higher risk of all-cause (HR 1.47, 95% CI 1.22–1.77) and cardiovascular mortality (HR 2.08, 95% CI 1.52–2.86). ROC analysis showed that the area under the curves (AUCs) of 0.692, 0.662, 0.644, and 0.625 for predicting all-cause mortality, and 0.712, 0.692, 0.687, and 0.660 for cardiovascular mortality at 1, 3, 5, and 10 years. ConclusionElevated NLR is associated with increased risk of cardiovascular and all-cause mortality, and NLR may independently predict outcomes in individuals with hypertension.

Association between diabetic status and risk of all-cause and cause-specific mortality on dialysis following first kidney allograft loss.

Diabetes mellitus (DM) is associated with a greater risk of mortality in kidney transplant patients, primarily driven by a greater risk of cardiovascular disease (CVD)-related mortality. However, the associations between diabetes status at time of first allograft loss and mortality on dialysis remain unknown. All patients with failed first kidney allografts transplanted in Australia and New Zealand between 2000 and 2020 were included. The associations between diabetes status at first allograft loss, all-cause and cause-specific mortality were examined using competing risk analyses, separating patients with diabetes into those with pre-transplant DM or post-transplant diabetes mellitus (PTDM). Of 3782 patients with a median (IQR) follow-up duration of 2.7 (1.1-5.4) years, 539 (14%) and 390 (10%) patients had pre-transplant DM or developed PTDM, respectively. In the follow-up period, 1336 (35%) patients died, with 424 (32%), 264 (20%) and 199 (15%) deaths attributed to CVD, dialysis withdrawal and infection, respectively. Compared to patients without DM, the adjusted subdistribution HRs (95%CI) for pre-transplant DM and PTDM for all-cause mortality on dialysis were 1.47 (1.17-1.84) and 1.47 (1.23-1.76), respectively; for CVD-related mortality were 0.81 (0.51-1.29) and 1.02 (0.70-1.47), respectively; for infection-related mortality were 1.84 (1.02-3.35) and 2.70 (1.73-4.20), respectively; and for dialysis withdrawal-related mortality were 1.71 (1.05-2.77) and 1.51 (1.02-2.22), respectively. Patients with diabetes at the time of kidney allograft loss have a significant survival disadvantage, with the excess mortality risk attributed to infection and dialysis withdrawal.

The Effect of Out-of-Hours Admission on Mortality in Patients Who Underwent Thrombectomy Due to Ischemic Stroke.

It is important to investigate the factors that may delay the diagnosis and treatment process of ischemic stroke. The aim of this study was to investigate whether in-hospital mortality increased in patients who presented to the emergency department out-of-hours and underwent thrombectomy. A total of 59 patients who applied to the emergency department between January 1, 2018 and November 1, 2021 and underwent thrombectomy due to ischemic stroke were included in the study. Patient age, gender, thrombectomy success (successful recanalization), in-hospital mortality status, intracranial hemorrhage status after thrombectomy, and out-of-hours admission status were recorded and compared according to out-of-hours admission status. Twenty-seven (45.8%) patients were male, and the median age was 74 (61-81) years. Forty-two (71.2%) patients applied to the emergency department out-of-hours. In-hospital mortality occurred in 27 (45.8%) patients. There was no statistically significant difference in out-of-hours admission status between the non-survivor group and the survivor group (non-survivor: 24 [75%]; survivor: 18 [66.7%], p = 0.481). Nor was a statistically significant difference found in the intracranial hemorrhage complication rate of the patients admitted out-of-hours compared to the patients admitted during working hours (out-of-hours: 17 [40.5%]; during working hours: 6 [35.3%], p = 0.712). No statistically significant difference was found in the rate of in-hospital mortality and intracranial bleeding complications in patients who underwent thrombectomy out of working hours compared to during working hours.

The Impact of Age Over 80 Years on Outcomes in Geriatric Patients with Acute Pancreatitis: A Single Center Experience

The aim of this study is to evaluate the prognosis and mortality of acute pancreatitis (AP) in older subjects and compare octogenarians (≥80 years) with nonoctogenarians (age &amp;lt;80 years). The medical records of elderly patients who were followed up with the diagnosis of AP at our clinic between January 2018 and December 2021 were retrospectively analyzed. The etiology of AP, comorbidities, laboratory parameters, intensive care unit (ICU) admission, and mortality were noted. Among survivors, one-year mortality status was also recorded. Disease severity, in-hospital mortality and one-year mortality were compared. A total of 206 older patients (60 octogenarian, 146 nonoctogenariean) were recruited to the study. Of them, 115 (56%) were female and the mean age was 76.1±7.3 years. Severity of AP didn’t differ between octogenarians and nonctogenarians (p&amp;gt;0.05). ICU admission was seen in 13% of octogenarians and 11% of nonoctogenarians (p&amp;gt;0.05). In-hospital mortality occurred in 8.3% of octogenarians and 6.8% of nonoctogenarians (p&amp;gt;0.05). After discharge, one-year mortality occurred in 20% of octogenarians and 6.6% of nonoctogenarians (p&amp;lt;0.01). In multivariate analysis severe AP (OR:24.940;%95CI:1.013–95.609; p=0.01), ICU admission (OR:10.244;%95CI:1.399–74.990; p=0.01) and chronic kidney disease(CKD) (OR:9.840;%95CI:1.013–95.609; p=0.04) were independent risk factors for in-hospital mortality, and ≥80 years (OR:2.984;%95 CI:1.116–7.980; p =0.03) and neurological disorders (OR:4.424;%95CI:1.480–13.226; p &amp;lt;0.01) were independent factors related to one-year mortality. Our results showed that advenced age has not a significant effect on the course of AP in elderly. Comorbidities play important role in short- and long-term outcomes in elderly. Larger prospective trials are needed to draw more definitive conclusions.

Short and long-term outcomes of decompressive craniectomy among patients with non-traumatic acute intracranial hypertension; A 5-year retrospective analysis of a referral center

BackgroundDecompressive craniectomy (DC) is performed for the management of the patients with acutely elevated intracranial pressure (ICP). Considering the paucity of the evidence regarding the outcome predictors in patients with non-traumatic raised ICP, we aimed to assess short- and long-term outcome related factors in DC subjects. MethodsIn this cross-sectional study, health records of the patients who underwent DC for non-traumatic etiologies over the five years were interrogated and demographic data, clinical features, operative findings, and follow-up notes were collected. The primary short- and long-term outcomes were in-hospital mortality and functional status, respectively. Functional status was evaluated using Glasgow Outcome Scale (GOS) at 6-month follow-up. ResultsOf the 223 eligible patients, 113 (50.7 %) were male and the mean age was 48.68 ± 13.97 years. In-hospital mortality rate was 48.4 % (n = 108). Of the survivors, 28 (30.4 %) had favorable outcomes (GOS 4–5). The most common post-operative complications were infection with respiratory source (n = 52, 23 %) and external cerebral herniation (n = 61, 27.4 %). Presence of diabetes mellitus (DM) (OR = 6.09; 95 % CI = 2.0–18.51; P = 0.001), subarachnoid hemorrhage (SAH) (OR = 5.61; 95 % CI = 1.47––21.3; P = 0.01), and prolonged duration of ICU-stay (OR = 1.37; 95 % CI: 1.03, 1.24; P = 0.006) were associated with in-hospital mortality. Also, preexisting DM was two times more prevalent among the subjects deceased in the hospital than those who survived. ConclusionsConcomitant SAH, DM, and prolonged ICU stay were associated with increased in-hospital mortality. In addition, preexisting DM may increase mortality rates, likely irrespective of age factor.

Does the healthy vaccinee bias rule them all? Association of COVID-19 vaccination status and all-cause mortality from an analysis of data from 2.2 million individual health records

ObjectivesWe investigated the validity of claims of the healthy vaccinee effect (HVE) in COVID-vaccine studies by analyzing associations between all-cause mortality (ACM) and COVID-19 vaccination status. MethodsApproximately 2.2 million individual records from two Czech health insurance companies were retrospectively analyzed. Each age group was stratified according to the vaccination status (unvaccinated vs. individuals less than 4 weeks vs. more than 4 weeks from Doses 1, 2, 3, and 4 or more doses of vaccine). ACMs in these groups were computed and compared. ResultsConsistently over datasets and age categories, ACM was substantially lower in the vaccinated than unvaccinated groups regardless of the presence or absence of a wave of COVID-19 deaths. Moreover, the ACMs in groups more than 4 weeks from Doses 1, 2, or 3 were consistently several times higher than in those less than 4 weeks from the respective dose. HVE appears to be the only plausible explanation for this, which is further corroborated by a created mathematical model. ConclusionsIn view of the presence of HVE, the baseline difference in the frailty of vaccinated and unvaccinated populations in periods without COVID-19 must be taken into account when estimating COVID-19 vaccine effectiveness from observational data.

A Greater Variety of Social Activities Is Associated With Lower Mortality Risk.

More frequent engagement in social activity is often associated with better physical health outcomes. Yet, less is known about whether engagement in a greater variety of social activities such as a mix of volunteering and attending club meetings (social activity variety) is important for health. The current study assessed whether social activity variety relates to mortality risk after adjusting for social activity frequency, nonsocial activity frequency and variety, and sociodemographic covariates, and how this relationship varies depending on age. Using data from the Health and Retirement Study, we included 5,017 adults aged 51 and older who completed questions about social activity participation in 2008 and whose mortality status was recorded up to 2019. We also examined whether age moderated the relationship between social activity variety and mortality risk. Cox proportional hazard model analyses revealed that those with higher activity variety in social activities were more likely to survive over the following 11 years than those with low social activity variety. Moreover, age moderation indicated that the association between social activity variety with mortality risk was stronger among the oldest adults. Findings suggest that a greater variety of social activities is linked to mortality risk even after adjusting for social activity frequency, nonsocial activities, and health status across adulthood.

Smoking is associated with higher short-term risk of revision and mortality following primary hip or knee arthroplasty: a cohort study of 272,640 patients from the Dutch Arthroplasty Registry.

Patients actively smoking at the time of primary hip or knee arthroplasty are at increased risk of direct perioperative complications. We investigated the association between smoking status and risk of revision and mortality within 2 years following hip or knee arthroplasty. We used prospectively collected data from the Dutch Arthroplasty Register. All primary total hip arthroplasties (THAs), total knee arthroplasties (TKAs), and unicondylar knee arthroplasties (UKAs) with > 2 years' follow-up were included (THA: n = 140,336; TKA: n = 117,497; UKA: n = 14,807). We performed multivariable Cox regression analyses to calculate hazard risks for differences between smokers and non-smokers, while adjusting for confounders (aHR). The smoking group had higher risk of revision (THA: aHR 1.3, 95% confidence interval [CI] 1.1-1.4 and TKA: aHR 1.4, CI 1.3-1.6) and risk of mortality (THA: aHR 1.4, CI 1.3-1.6 and TKA: aHR 1.4, CI 1.2-1.6). Following UKA, smokers had a higher risk of mortality (aHR 1.7, CI 1.0-2.8), but no differences in risk of revision were observed. The smoking group had a higher risk of revision for infection following TKA (aHR 1.3, CI 1.0-1.6), but not following THA (aHR 1.0, CI 0.8-1.2). This study showed that the risk of revision and mortality is higher for smokers than for non-smokers in the first 2 years following THA and TKA. Smoking could contribute to complications following primary hip or knee arthroplasty.

Effectiveness of nurse-led fever, sugar-hyperglycemia, and swallowing bundle care on clinical outcome of patients with stroke at a tertiary care center: A randomized controlled trial.

Stroke is a medical emergency, the leading cause of death, and a significant cause of disability in developing countries. The primary goals of stroke management focus on reducing disability, which needs prompt treatment in time. Fever, sugar-hyperglycemia, and swallowing (FeSS) bundle are a promising nurse-led composite for reducing disability and death. The present study aims to assess the effect of FeSS bundle care on disability, functional dependency, and death among acute stroke patients. A randomized controlled trial was conducted among 104 acute stroke patients, who were admitted within the first 48 h of stroke symptoms and had no previous neurological deficits. Randomization was stratified based on gender and type of stroke. The intervention group received FeSS bundle care, which included nurse-led fever and sugar management for the first 72 h, and a swallowing assessment done within the first 24 h or before the first oral meal. A follow-up assessment was done after 90 days to assess the disability, functional dependency, and mortality status using a modified Rankin scale and Barthel index. No significant difference was noted in the 90-day disability and functional dependency between the groups. A reduction in mortality was noted in the intervention group. The risk ratio for mortality between groups was 2.143 (95% confidence interval: 0.953-4.820). Although no significant reduction in disability, there was a reduction in mortality in the intervention group. Hence, the study suggested the promotion of nurse-led intervention using the FeSS bundle in stroke units.

Survival Status and Predictors of Mortality Among Low-birth-weight Neonates in Southern Ethiopia: A Prospective Follow-up Study

Background Due to anatomical and physiological immaturity low-birth-weight (LBW) neonates are at risk for different complications which may lead to death at a specified period after birth. Therefore, this study aimed to assess the survival rate and predictors of mortality among LBW neonates. Methods A hospital-based prospective cohort study design was conducted among 768 LBW neonates. The Cox proportional hazard model was used to identify predictors of mortality among LBW neonates. Result The mortality rate of low birth weight was 38.8 (95% CI: 33.9–44.3) per 1,000 child-day observations. Parity (AHR = 1.47 [95% CI: 1.06–2.05]), Birth weight &lt;1000 gram (AHR = 4.70 [95% CI: 2.36–9.35]), Birth weight &lt;1500 gram (AHR = 1.62 [95% CI: 1.16–2.27]), Neonatal sepsis (AHR = 2.41 [95% CI: 2.25–2.91]), Birth asphyxia (AHR = 1.46 [95% CI = 1.02–2.08]), Kangaroo mother care (KMC) (AHR = 0.35 [95% CI: 0.24–0.49]), were statistically significantly associated with mortality. Conclusions The findings of this study revealed that the incidence rate of mortality among LBW neonates was high. Practising KMC for all LBW neonates and appropriate treatment of neonatal sepsis and birth asphyxia were strongly recommended to reduce mortality among LBW neonates.

Survival Status and Predictors of Mortality Among Children Admitted With Acute Lymphocytic Leukemia at Cancer Treatment Hospitals in Addis Ababa, Ethiopia.

Acute lymphocytic leukemia is a cancer affecting the blood and bone marrow and is the most frequently diagnosed cancer among children. In Ethiopia, it represents the predominant form of childhood leukemia, comprising approximately 80% of cases and serving as a leading cause of childhood cancer-related deaths. Therefore, the objective of this study is to examine the survival status and factors that may predict mortality in children admitted with acute lymphocytic leukemia at cancer treatment hospitals in Addis Ababa, Ethiopia. A retrospective follow-up study was conducted at cancer treatment hospitals in Addis Ababa, focusing on children diagnosed with acute lymphocytic leukemia. The investigation covered records from January 1, 2017, to December 30, 2023, encompassing a sample of 230 study records. Variables with a P-value below 0.25 in the bivariate analysis were selected for entry into the multivariable analysis. Subsequently, variables demonstrating a P-value less than 0.05 in the multivariable Cox proportional hazards model were deemed statistically significant. The cumulative proportion of survival was 98.3% (95%CI: 94.8, 99.5), 89.2% (95%CI: 82.0, 93.6), and 24.1% (95%CI: 8.43, 44.1) at the end of the 20th, 40th, and 60th month, respectively. The incidence rate of mortality among cohort of children admitted with acute lymphocytic leukemia was 0.45 per 100 child months. History of relapse (AHR: 2.48; 95%CI: 1.01, 6.08) and infection (AHR: 2.34; 95%CI: 1.03, 5.31) were independent predictors of mortality among children admitted with acute lymphocytic leukemia. The likelihood of mortality increased in the later stages of follow-up for children admitted with acute lymphocytic leukemia, and the incidence density rate of mortality in this group was lower compared to previous reports from other regions. Furthermore, independent predictors of mortality among children with acute lymphocytic leukemia included a history of relapse and infection.

Abstract WMP47: Neighborhood Socio-Economic Status as a Predictor of All-Cause Long-Term Post-Stroke Mortality

Background: Previous studies have shown that neighborhood socioeconomic status may be associated with post-stroke mortality. However, these studies did not adjust for stroke severity. We aim to determine the association between neighborhood of residence on long-term mortality after stroke. Methods: Within our population of 1.3 million in the Greater Cincinnati Northern Kentucky area, incident strokes among adult residents were ascertained at all area hospitals during calendar years 2005, 2010 and 2015. Participants addresses were used to geocode and determine their census tract and then used a validated index to determine neighborhood socio-economic status. We used national death index data to determine mortality status at 5 years post stroke. Individuals who survived at least 30 days were included in the analysis. We used cox proportional hazards to determine the association between neighborhood of residence deprivation and case fatality rate after stroke. Results: Among 4514 incident ischemic strokes, there were 1719 deaths over 5 years; for an all-cause post-stroke mortality rate of 38.08% among survivors of 30 days post-stroke. Similarly, there were 552 intracerebral hemorrhages with 224 deaths over 5 years: yielding an all-cause post-stroke mortality rate of 40.58%. Individuals in the quartile of neighborhoods with lowest neighborhood socio-economic status had 1.3 times the all-cause post-stroke mortality rate (HR 1.29 95% CI 1.08-1.54); after adjustment for age sex, race, and year of study (2005, 2010 and 2015). After adjustment for age, race, sex, year of study and NIH stroke scale score, individuals living in the quartile of neighborhoods with the lowest neighborhood socio-economic status had 1.29 times the risk of dying (HR 1.29 95% CI 1.09-1.53). We found insufficient evidence of an association between neighborhood socio-economic status and 5-year case fatality rate among intracerebral hemorrhages. Conclusion: Rates of all-cause post-stroke long-term mortality were higher among patients with ischemic stroke who lived in neighborhoods with lowest quartile of socio-economic status. This effect persisted even after adjusting for stroke severity.

Association between cytomegalovirus seropositivity and all-cause mortality: An original cohort study.

To examine the association between cytomegalovirus (CMV) seropositivity and all-cause mortality in a nationwide cohort of US adults. We obtained data from the National Health and Nutrition Examination Survey III (1988-1994), including 16,547 participants aged 18-90 years old with CMV serology assessments. Mortality status was ascertained until December 2019 using the National Death Index linkage data. The Cox proportional hazard model was applied to estimate the association between CMV seropositivity and mortality. During a median follow-up of 26.3 years, 6,930 deaths were recorded. CMV seropositivity was associated with a higher hazard of all-cause mortality after adjusting for attained age, sex, and ethnicity (HR: 1.22, 95% CI: 1.10, 1.36, p < 0.001). The magnitude of the association attenuated slightly after adjusting further for body mass index, family income, smoking status, diabetes, and self-reported cancer history (HR = 1.11, 95% CI: 1.00, 1.23, p = 0.04). While the association was observed for both men and women, it was only statistically significant among non-Hispanic white people (HR: 1.16, 95% CI: 1.06, 1.26, p = 0.001) but not among other ethnic populations. CMV seropositivity might be an independent risk factor for all-cause mortality among US adults. If the findings are validated in an independent population, further research is needed to unveil the biological mechanisms driving the increased mortality with CMV seropositivity.

The association between TyG and all-cause/non-cardiovascular mortality in general patients with type 2 diabetes mellitus is modified by age: results from the cohort study of NHANES 1999–2018

BackgroundThe prognostic value of triglyceride-glucose (TyG) index in general type 2 diabetes mellitus (T2DM) patients is still unclear. Therefore, we aimed to determine the associations between TyG and all-cause/cause-specific death in a T2DM cohort and explore whether such associations would be modified by age.MethodsA total of 3,376 patients with T2DM from the National Health and Nutrition Examination Survey (NHANES) 1999–2018 were selected and divided into the younger group (< 65 yrs) and the older group (≥ 65 yrs). Baseline TyG was calculated and cause-specific mortality status [cardiovascular (CV), cancer, and non-CV] was determined by the NHANES Public-Use Linked Mortality Files through 31 December 2019. Multivariate Cox and restricted cubic spline (RCS) regression models were used to evaluate the association between TyG and all-cause/cause-specific mortality. Interaction between TyG and age to mortality was also evaluated. Sensitivity analyses were performed in patients without cardiovascular disease, chronic kidney disease, or insulin treatment.ResultsDuring a median follow-up of 107 months, 805 all-cause deaths occurred, of which 250 and 144 were attributed to CV and cancer deaths. There was a significant age interaction to the association between TyG and all-cause/non-CV mortality. After fully adjusting for potential confounding factors, higher TyG was associated with an increased risk of all-cause [TyG per unit increase Hazard Ratio (HR) 1.33, 95% Confidence Interval (CI) 1.06–1.66, p = 0.014] and non-CV mortality (TyG per unit increase HR 1.54, 95% CI 1.18–2.01, p = 0.002) only in the younger group, but not in the older group. There was no significant association between TyG and CV/cancer death in the total cohort and two age subgroups. Similar results were found in RCS and sensitivity analyses.ConclusionIn a national sample of patients with T2DM in the United States, we found that the association between TyG and all-cause/non-CV death was modified by age. Higher TyG was only associated with an increased risk of all-cause/non-CV only in T2DM patients younger than 65 years old, but not in older patients.

Open-heart surgery in patients with cirrhosis: Variables associated with survival outcomes

BackgroundUnderstanding the risks of performing open-heart surgery in patients with cirrhosis is of critical importance given increased risks of morbidity and mortality. We analyzed the variables and risk scoring systems associated with survival and postoperative outcomes among patients with cirrhosis after open-heart surgery. MethodsThis is a single-center retrospective study of 32 patients with cirrhosis who underwent open-heart surgery at our institution between August 2020 – September 2022. Patients were stratified by mortality status to compare demographic and clinical variables. Survival was assessed using Kaplan-Meier curves and log-rank tests for the following variables: Model for End-Stage Liver Disease (MELD) score (<11 vs ≥11), Child-Turcotte-Pugh (CTP) class (A vs B vs C), Society of Thoracic Surgeons (STS) score (predicted mortality <4 vs 4 to 8 vs ≥8), European System for Cardiac Operative Risk Evaluation (EuroSCORE) II (<3.3 vs ≥3.3), and cardiopulmonary bypass (off pump vs on pump). ResultsOverall survival for our patient cohort was 93.8% at 30 days, 81.3% at 1 year, and 78.1% at 2 years postoperatively. Increased preoperative creatinine (p = 0.049), preoperative total bilirubin (p = 0.017), intraoperative blood products (p = 0.016), and intensive care unit length of stay (p = 0.001) were significantly associated with decreased survival. Among the risk scoring systems, only CTP class was significantly associated with survival (p < 0.0001). ConclusionsWe demonstrated high short-term and long-term survival among patients with cirrhosis after open-heart surgery, suggesting that select patients may be operative candidates. Among risk-scoring systems, only CTP was significantly associated with survival, which may guide future risk stratification strategies.
