Aligning antimicrobial resistance surveillance with schistosomiasis research: an interlinked One Health approach.

One Health surveillance involves the analysis of human, animal and environmental samples, recognising their interconnectedness in health systems. Such considerations are crucial to investigate the transmission of many pathogens, including drug-resistant bacteria and parasites. The highest rates of antimicrobial resistance (AMR)-associated deaths are observed in sub-Saharan Africa, where concurrently the waterborne parasitic disease schistosomiasis can be highly endemic in both humans and animals. Although there is growing acknowledgment of significant interactions between bacteria and parasites, knowledge of relationships between schistosomes, microbes and AMR remains inadequate. In addition, newly emergent research has revealed the previously underappreciated roles of animals and the environment in both AMR and schistosomiasis transmission. We consider shared environmental drivers and colonisation linkage in this narrative review, with a focus on extended-spectrum beta-lactamase-mediated resistance among bacteria from the Enterobacteriaceae family, which is exceedingly prevalent and responsible for a high burden of AMR-associated deaths. Then we examine novel findings from Malawi, where the landscapes of AMR and schistosomiasis are rapidly evolving, and make comparisons to other geographic areas with similar co-infection epidemiology. We identify several knowledge gaps that could be addressed in future research, including the need to characterise the impact of intestinal schistosomiasis and freshwater contact on intestinal AMR colonisation, before proposing a rationale for connecting AMR surveillance and schistosomiasis research within a One Health framework.

Pneumonia in Geriatric Patients and Prediction of Mortality Based on the Pneumonia Severity Index (PSI), CURB-65, Frailty Index (FI), and FI-Lab21 Scores.

Background Elderly individuals have higher rates of morbidity, death, and financial burden due to community-acquired pneumonia (CAP). Objectives The study aimed to assess the outcomes of geriatric pneumonia patients and the prediction of mortality based on the pneumonia severity index (PSI), CURB-65 (confusion, urea, respiratory rate, blood pressure, and 65-year-old score), frailty index (frailty index), and FI-Lab21 (21-item frailty index based on laboratory) scores. Methods A prospective observational study was conducted on 100 elderly patients (≥ 65 years) with CAP. PSI, CURB-65, FI, and FI-Lab21 scores were determined. The outcome measures were 30-day mortality and the risk factors of mortality. The mortality predictive value of scores were compared. Results The mean age of the study subjects was 72.14 ± 6.1 years. Specifically, 76 (76%) were male, and 24 (24%) were females.During the follow-up, there was a 30-day mortality rate of 57%. On performing multivariate regression, the PSI score and severely frail were significant independent risk factors of mortality, with an odds ratio of 1.046 and 52.213, respectively. Area under the ROC curve (AUC) showed that the performance of the PSI score (AUC: 0.952; 95% CI: 0.910-0.994), CURB-65 score (AUC: 0.936; 95% CI: 0.893-0.978), and severely frail (AUC: 0.907; 95% CI: 0.851-0.962) was outstanding, while FI-Lab21 (AUC: 0.515; 95% CI: 0.400-0.631) was non-significant. Among all the parameters, the PSI score was the best predictor of mortality at the cutoff points of >121 with a diagnostic accuracy of 92%. Conclusion CAP in the elderly carries a high mortality rate. Out of PSI, CURB-65, FI, and FI-Lab21 scores, the PSI holds the best predicting ability for mortality.

Trend of Mortality Due to Congenital Anomalies in Children Younger Than 5 Years in Eastern China, 2012-2021: Surveillance Data Analysis.

As one of the leading causes of child mortality, deaths due to congenital anomalies (CAs) have been a prominent obstacle to meet Sustainable Development Goal 3.2. We conducted this study to understand the death burden and trend of under-5 CA mortality (CAMR) in Zhejiang, one of the provinces with the best medical services and public health foundations in Eastern China. We used data retrieved from the under-5 mortality surveillance system in Zhejiang from 2012 to 2021. CAMR by sex, residence, and age group for each year was calculated and standardized according to 2020 National Population Census sex- and residence-specific live birth data in China. Poisson regression models were used to estimate the annual average change rate (AACR) of CAMR and to obtain the rate ratio between subgroups after adjusting for sex, residence, and age group when appropriate. From 2012 to 2021, a total of 1753 children died from CAs, and the standardized CAMR declined from 121.2 to 62.6 per 100,000 live births with an AACR of -9% (95% CI -10.7% to -7.2%; P<.001). The declining trend was also observed in female and male children, urban and rural children, and neonates and older infants, and the AACRs were -9.7%, -8.5%, -8.5%, -9.2%, -12%, and -6.3%, respectively (all P<.001). However, no significant reduction was observed in children aged 1-4 years (P=.22). Generally, the CAMR rate ratios for male versus female children, rural versus urban children, older infants versus neonates, and older children versus neonates were 1.18 (95% CI 1.08-1.30; P<.001), 1.20 (95% CI 1.08-1.32; P=.001), 0.66 (95% CI 0.59-0.73; P<.001), and 0.20 (95% CI 0.17-0.24; P<.001), respectively. Among all broad CA groups, circulatory system malformations, mainly deaths caused by congenital heart diseases, accounted for 49.4% (866/1753) of deaths and ranked first across all years, although it declined yearly with an AACR of -9.8% (P<.001). Deaths due to chromosomal abnormalities tended to grow in recent years, although the AACR was not significant (P=.90). CAMR reduced annually, with cardiovascular malformations ranking first across all years in Zhejiang, China. Future research and practices should focus more on the prevention, early detection, long-term management of CAs and comprehensive support for families with children with CAs to improve their survival chances.

Fine particulate matter air pollution and health implications for Nairobi, Kenya

Background: Continuous ambient air quality monitoring in Kenya has been limited, resulting in a sparse data base on the health impacts of air pollution for the country. We have operated a centrally located monitor in Nairobi for measuring fine particulate matter (PM2.5), the pollutant that has demonstrated impact on health. Here, we describe the temporal levels and trends in PM2.5 data for Nairobi and evaluate associated health implications. Methods: We used a centrally located reference sensor, the beta attenuation monitor (BAM-1022), to measure hourly PM2.5 concentrations over a 3-year period (21 August 2019 to 20 August 2022). We used, at minimum, 75% of the daily hourly concentration to represent the 24-hour concentrations for a given calendar day. To estimate the deaths attributable to air pollution, we used the World Health Organization (WHO) AirQ+ tool with input as PM2.5 concentration data, local mortality statistics, and population sizes. Results: The daily (24-hour) mean (±SEM) PM2.5 concentration was 19. 2 ± 0.6 (µg/m3). Pollutant levels were lowest at 03:00 and, peaked at 20:00. Sundays had the lowest daily concentrations, which increased on Mondays and remained high through Saturdays. By season, the pollutant concentrations were lowest in April and highest in August. The mean annual concentration was 18.4 ± 7.1 (µg/m3), which was estimated to lead to between 400 and 1,400 premature deaths of the city’s population in 2021 hence contributing 5%–8% of the 17,432 adult deaths excluding accidents when referenced to WHO recommended 2021 air quality guideline for annual thresholds of 5 µg/m3. Conclusion: Fine particulate matter air pollution in Nairobi showed daily, day-of-week, and seasonal fluctuations consistent with the anthropogenic source mix, particularly from motor vehicles. The long-term population exposure to PM2.5 was 3.7 times higher than the WHO annual guideline of 5 µg/m3 and estimated to lead to a substantial burden of attributable deaths. An updated regulation targeting measures to reduce vehicular emissions is recommended.

Prevalence, Patient Awareness, Treatment, and Control of Hypertension in Canadian Adults With Common Comorbidities

BackgroundWhether certain medical conditions are associated with blood pressure (BP) treatment and control is unclear. MethodsUsing the Canadian Health Measures Survey (2007-2019), BP was assessed according to the presence of selected comorbidities, including prior heart attack or stroke, dyslipidemia, chronic kidney disease, diabetes mellitus, obstructive sleep apnea, and overweight or obesity. ResultsA total of 5,841,453 people, representing 23.0% (95% confidence interval [CI] 21.7%-24.2%) of Canadian adults, were hypertensive. The adjusted odds ratio (aOR) of having hypertension treated and controlled was higher in people with the following conditions, as compared to people without these conditions: a prior heart attack or stroke (aOR 3.15; 95% CI 2.31-4.31); dyslipidemia (aOR 2.51; 95% CI 1.96-3.21); obstructive sleep apnea (aOR 1.95; 95% CI 1.19-3.21); overweight or obesity (aOR 1.51; 95% CI 1.18-1.94); chronic kidney disease (aOR 1.49; 95% CI 1.13-1.95); and diabetes (aOR 1.44; 95% CI 1.12-1.86). Individuals without any of these comorbidities were less likely to have BP that is treated and controlled (aOR 0.34; 95% CI 0.25-0.48). Moreover, the prevalence of BP treatment and control was low among many people without prior heart attack or stroke, even those with a moderate (aOR 0.25; 95% CI 0.17-0.37) or high (aOR 0.10; 95% CI 0.06-0.16) Framingham risk. ConclusionsLarge differences in levels of BP control exist across comorbidity profiles, and the greatest gaps are seen in individuals without recognized comorbidities, even those who have a moderate-to-high Framingham risk. Efforts to optimize BP control and narrow care gaps, especially in individuals without recognized comorbidities, are necessary to reduce the burden of cardiovascular disease and premature death in Canada.

Global burden of non-communicable diseases attributable to kidney dysfunction with projection into 2040.

Spatiotemporal disparities exist in the disease burden of non-communicable diseases (NCDs) attributable to kidney dysfunction, which has been poorly assessed. The present study aimed to evaluate the spatiotemporal trends of the global burden of NCDs attributable to kidney dysfunction and to predict future trends. Data on NCDs attributable to kidney dysfunction, quantified using deaths and disability-adjusted life-years (DALYs), were extracted from the Global Burden of Diseases Injuries, and Risk Factors (GBD) Study in 2019. Estimated annual percentage change (EAPC) of age-standardized rate (ASR) was calculated with linear regression to assess the changing trend. Pearson's correlation analysis was used to determine the association between ASR and Sociodemographic Index (SDI) for 21 GBD regions. A Bayesian age-period-cohort (BAPC) model was used to predict future trends up to 2040. Between 1990 and 2019, the absolute number of deaths and DALYs from NCDs attributable to kidney dysfunction increased globally. The death cases increased from 1,571,720 (95% uncertainty interval [UI]: 1,344,420-1,805,598) in 1990 to 3,161,552 (95% UI: 2,723,363-3,623,814) in 2019 for both sexes combined. Both the ASR of death and DALYs increased in Andean Latin America, the Caribbean, Central Latin America, Southeast Asia, Oceania, and Southern Sub-Saharan Africa. In contrast, the age-standardized metrics decreased in the high-income Asia Pacific region. The relationship between SDI and ASR of death and DALYs was negatively correlated. The BAPC model indicated that there would be approximately 5,806,780 death cases and 119,013,659 DALY cases in 2040 that could be attributed to kidney dysfunction. Age-standardized death of cardiovascular diseases (CVDs) and CKD attributable to kidney dysfunction were predicted to decrease and increase from 2020 to 2040, respectively. NCDs attributable to kidney dysfunction remain a major public health concern worldwide. Efforts are required to attenuate the death and disability burden, particularly in low and low-to-middle SDI regions.

Nationwide burden of sudden cardiac death among patients with a psychiatric disorder

Abstract Background and aim Patients with psychiatric disorders have increased all-cause mortality compared to the general population. Previous research has shown that they have a 4-fold increased risk of sudden cardiac death (SCD) among the young. However, the risk across all age groups remains unknown. Purpose To investigate the incidence of SCD in patients with psychiatric disorders aged 18-90 years in the Danish population by systematically reviewing all deaths in one year. Methods We examined all deaths in Denmark among residents aged 18-90 years in 2010 by reviewing death certificates and autopsy reports. All deaths were categorized as non-SCD, or SCD, based on the available information. Psychiatric disorder was defined according to ICD-10 criteria, or by redemption of a prescription for psychotropic medication within one year prior to death. Results Out of 4.3 million residents in 2010 aged 18-90 years, we observed 45 703 deaths of which 6 002 were SCD. Overall, the incidence of SCD was 4.35 times (CI: 4.20-4.50, p-value &amp;lt;0.001) higher among patients with psychiatric disorders than in the general population and was age dependent (p-value &amp;lt;0.001). When adjusting for age, sex, and comorbidities, psychiatric disorders were independently associated with SCD, with a hazard ratio (HR) of 2.46 (2.33-2.60, p-value: &amp;lt;0.001), with highest SCD risk among patients suffering from schizophrenic disorders with a HR of 5.27 (4.23-6.56 p-value &amp;lt;0.001). Furthermore, patients with psychiatric disorders had an expected 10-year excess loss of life of which 13% was caused by SCD. Conclusion The rate of SCD in patients with psychiatric disorders was 4 times higher than in the general population. Having a psychiatric disorder is independently associated with SCD. Life-expectancy for an 18-year-old with a psychiatric disorder is projected to be 10-years shorter in comparison.Incidence rate of SCD by age groupExcess loss of life-years

Associations between PM2.5 Components and Mortality of Ischemic Stroke, Chronic Obstructive Pulmonary Disease and Diabetes in Beijing, China.

Ischemic stroke (IS), chronic obstructive pulmonary disease (COPD) and diabetes mellitus (DM) account for a large burden of premature deaths. However, few studies have investigated the associations between fine particular matter (PM2.5) components and mortality of IS, COPD and DM. We aimed to examine these associations in Beijing, China. Data on daily mortality, air pollutants and meteorological factors from 2008 to 2011 in Beijing were collected. Daily concentrations of five PM2.5 components, namely, sulfate ion (SO42-), ammonium ion (NH4+), nitrate ion (NO3-), organic matter (OM) and black carbon (BC), were obtained from the Tracking Air Pollution (TAP) database in China. The association between PM2.5 components and daily deaths was explored using a quasi-Poisson regression with the distributed lag nonlinear model (DLNM). The average daily concentrations of SO42-, NH4+, NO3-, OM and BC were 11.24, 8.37, 12.00, 17.34 and 3.32 μg/m3, respectively. After adjusting for temperature, relative humidity, pressure, particulate matter less than 10 μm in aerodynamic diameter (PM10), nitrogen dioxide (NO2) and sulfur dioxide (SO2), an IQR increase in OM at lag day 2 and lag day 6 was associated with an increased DM mortality risk (RR 1.038; 95% CI: 1.005-1.071) and COPD mortality risk (RR 1.013; 95% CI: 1.001-1.026). An IQR increase in BC at lag day 0 and lag day 6 was associated with increased COPD mortality risk (RR 1.228; 95% CI: 1.017-1.48, RR 1.059; 95% CI: 1.001-1.121). Cumulative exposure to SO42- and NH4+ was associated with an increased mortality risk for IS, with the highest effect found for lag of 0-7 days (RR 1.085; 95% CI: 1.010-1.167, RR 1.083; 95% CI: 1.003-1.169). These effects varied by sex and age group. This study demonstrated associations of short-term exposure to PM2.5 components with increased risk of IS, COPD and DM mortality in the general population. Our study also highlighted susceptible subgroups.

Review of Hepatocellular Carcinoma and Liver Disease Prevalence

Abstract: The main reason for liver-related death globally is reported as cancer which results in most patients with cirrhosis, therefore in this article, we discuss the epidemiology of liver diseases and liver cancer in the world. : Ongoing review article efforts to address updated knowledge of study topics worldwide. Information on the prevalence and mortality of liver disease were extracted from Pubmed, Scopus, Web of Science and Cochrane Library. Ninety-two relevant in-depth consequent guide approaches and evidence-based choices were selected, associated with a knowledgeable collection of current, high-quality manuscripts. : Research reported that around 2.3 billion people in the world are infected with one of the hepatitis viruses that could cause liver cancer. The prevalence of non-alcoholic fatty liver disease, cirrhosis and liver cancer is varied worldwide. In the United States, each year 18600 males and 9000 females die from liver cancer. The global burden of deaths due to liver cancer was reported in 830,200 in 2020 that predicted to increase to &gt;55% by 2040. The major causes of liver cancer reported as hepatitis B (mainly in Asia) and C viruses. Regarding chronic liver disease that could cause cancer in some patients, the prevalence of non-alcoholic fatty liver disease (NAFLD) is estimated to be 6% to 35% worldwide. Steatosis and steatohepatitis affect 25% of the population worldwide. It is well known that the geographic distribution of different forms of liver disorders is divergent. Owing to population growth and ageing, liver cirrhosis and its development of cancer is an important health subject worldwide. Further studies regarding early detection of liver disease based on the easy and inexpensive test to score primary necroinflammation recommended advantageously.

Trends in the global, regional, and national burden of testicular cancer from 1990 to 2019: an observational study with 30-year global data.

Testicular cancer (TC) is currently the most common malignancy in young and middle-aged men. A comprehensive assessment of TC burden is in lack. Global incidence, deaths, and disability-adjusted life-years (DALYs) of TC from 1990 to 2019 were obtained. Estimated annual percentage change (EAPC) was calculated to quantify trends in TC changes during the period. Relationships between disease burden and age, socio-demographic index (SDI) levels, human development index (HDI) were further analyzed. Globally, incident cases of TC more than doubled from 1990 to 2019, together with an increasing of global age-standardized incidence rates (ASIR) of TC from 1.9 to 2.8. The age-standardized deaths rates (ASDR) remained stable from 0.31 to 0.28. The similar results were reflected in the DALYs. In 2019, the highest ASIR were found in Southern Latin America, Central Europe and Western Europe. Analogously, the highest ASDR were found in Southern Latin America followed by Central Latin America and Central Europe. The burden of incidence increased with SDI, appropriately reached a peak at about 0.78, and then declined. Similarly, the burden of deaths increased with SDI, met a maximum at about 0.7. From 1990 to 2019, the ASIR of TC has increased significantly, while the ASDR has been relatively stable and slightly decreased. The disease burden of TC is shifting to regions and countries with moderate to high levels of development. TC remains a rapidly growing global health problem, and new changes in TC burden should be considered when formulating new TC control policies.

Recovery Rate and Predictors for Cure of Admitted COVID-19 Patients in Ethiopia; A Systemic Review and Meta-Analysis

BACKGROUND. Despite the global efforts to curb COVID-19 infection using vaccines and drugs, the burden of illness, hospitalization, and death are continued as a deadly pandemic. Previous study finding estimated recovery time of 2 weeks for mild and 3 to 6 weeks for hospitalized cases. However, in low and middle-income countries like Ethiopia, recovery rate and viral negative conversion time are lowballed and underestimated due to the new variant incidence, limited resources and lacked skilled healthcare providers for admitted COVID-19 patients. This study aimed to estimate pooled recovery rate, and predictors for cure among admitted COVID-19 patients in Ethiopia. METHODS. Five electronic databases (Medline, PubMed, HINARY, Africa Journals Online, and Google Scholar) were searched. A total of 529 articles were extracted from cohort studies published in English spanning from December 30, 2019, to December 30, 2023. PRISMA guidelines were adhered to articles screening and extracted using Microsoft Excel. The quality of eligible articles was evaluated using the JBI checklist. The pooled effect size and adjusted odds ratio (AOR) with 95% confidence intervals were determined using the random-effect meta-regression using STATA version 17. Heterogeneity among studies was assessed using Cochran's Q-test, and the variation was estimated by I2, and presented in a forest plot. Subgroup analysis was also used to identify sources of heterogeneity among studies. RESULT. A total of 12 studies were included in the final meta-analysis. During the recovery screening of 5,152 admitted COVID-19 cases, 4,411 participants were discharged as cured. The pooled recovery rate was estimated at 90.6% (95% CI: 87.1-94.23, I² = 96.11%, P = 0.001). In subgroup analysis, Addis Ababa exhibited the highest recovery rate with 95.1%, followed by Oromia (94.6%), and Southern nation nationalities (SNN) region (91.55%). The recovery rate was higher for individuals aged 15-30 years (AHR = 2.01, 95% CI: 1.41-2.86, P = 0.001), males’ gender (AHR=1.46, 95% CI: 1.14-1.88, P=0.002), and cases admitted with ≥37.5°C (AHR = 2.01, 95% CI: 1.41-2.86, P = 0.001) compared to their counterparts. This manuscript is ongoing a submitted for registered in Prospero. CONCLUSION. In Ethiopia, nearly nine in every ten (90%) admitted COVID-19 cases recovered. However, the recovery rate exhibits a significant variation across each study region, setting, and pandemic phase. Therefore, healthcare providers prioritize care for critical cases to increase the overall survival rate of admitted patients.

Health Risks Associated with Tobacco Consumption in Humans: An Overview

Tobacco use remains a significant public health concern globally, with over 8 million anticipated deaths annually by 2030, despite declining rates in some high-income nations. Smoking is prevalent worldwide, particularly in developing and middle-income countries, where over 80% of smokers reside. The inhalation of tobacco substances leads to various diseases, including cancer and respiratory ailments, resulting in more deaths than AIDS, tuberculosis, and other major causes combined. Secondhand smoke exposure also poses significant health risks. The economic burden of tobacco-related deaths and diseases is substantial, especially in low- and middle-income economies, where almost 80% of tobacco-related deaths occur. Lack of awareness, societal influence, and ineffective enforcement of anti-tobacco laws contribute to widespread tobacco use. Although anti-tobacco campaigns and policies have shown some success, challenges persist, particularly in rural areas where tobacco dependence is high. In India, despite declining tobacco use attributed to awareness campaigns and increased taxes on cigarettes, certain demographics, such as middle-aged individuals, illiterates, and rural residents, continue to have high tobacco consumption rates due to inadequate implementation of anti-tobacco norms and limited access to information. Quitting smoking can significantly extend life expectancy and reduce the risk of smoking-related diseases. However, nicotine addiction poses a challenge, with only a small percentage of users successfully quitting without assistance. Professional support and cessation drugs can double the likelihood of successful quitting, and nicotine replacement therapy has shown effectiveness. Overall, there is no safe level of cigarette use, emphasizing the importance of comprehensive tobacco control efforts to mitigate the global health and economic impacts of tobacco use. This review deals with the health risks associated with tobacco consumption in humans. Keywords: Tobacco, Nicotine, Carcinogens, Cancer, Cardiovascular diseases.

Reducing air pollution does not necessarily reduce related adults' mortality burden: Variations in 177 countries with different economic levels

Prolonged exposure to PM2.5 is associated with increased mortality. However, reducing air pollution concentrations does not necessarily reduce the related burden of deaths. Here, we aim to estimate the variations in PM2.5-related mortality due to contributions from key factors – PM2.5 concentration, population exposure, and healthcare levels – for 177 countries from 2000 to 2018 at the 1-km grid scale according to the Global Mortality Exposure Model (GEMM) model. We find that global reductions in PM2.5-related deaths mainly come from high and upper-middle income countries, where lowered air pollutant concentration and better healthcare can offset mortality burdens caused by increasing exposed populations. Changes in population exposure to PM2.5 contribute the most (54 %) to change in global related deaths over the examined period, followed by changes in healthcare (−42 %) and pollution concentrations (4 %). The impacts vary across countries and regions within them due to other drivers, which are significantly influenced by development status. Policies aiming at reducing PM2.5 associated health risks need to account for country-specific balances of these key socioeconomic drivers.

Tobacco Cessation: A Review

Tobacco use is one of the biggest public health threats. Tobacco use is clearly a big hazard in terms of its magnitude and use in different forms. There is no safe level of exposure to tobacco, as users can experience health consequences at any age. Globally, it accounts for 8 million deaths every year, among which 1.3 million are due to second-hand smoking. It also has heavy social and economic burdens. Tobacco is the most important preventable cause of death and disease among adults. The burden of tobacco-related illness and death is heaviest in low- and middle-income countries, due to a lack of public awareness, inadequate healthcare infrastructure, and weak regulatory interventions. Most of the tobacco users who become aware of the dangers of tobacco-use want to quit. However, the nicotine present in tobacco products is highly addictive and makes it difficult to quit. Without proper cessation support, hardly 4% of users who attempt to quit tobacco use will succeed. Tobacco cessation in the adult population is essential to accelerate the reduction in smoking-related morbidity and mortality.

Burden, causes, and risk factors of perinatal mortality in Eastern Africa: a protocol for systematic review and meta-analysis.

Although global mortality rates in children under 5 years have decreased substantially in the last 30 years, there remain around 2.6 million stillbirths and 2.9 million neonatal deaths each year. The majority of these deaths occur in Africa and South Asia. To reduce perinatal deaths in East Africa, knowledge of the burden, but also the risk factors and causes of perinatal deaths are crucial. To the best of our knowledge, reviews have previously focused on the burden of perinatal deaths; here we aim to synthesize evidence on the burden, causes, and risk factors for perinatal mortality in East Africa. We will conduct a systematic literature search in Medline, Web of Science, EMBASE, Global Health, SCOPUS, Cochrane Library, CINAHL, HINARI, African Index Medicus, African Journals Online (AJOL), and WHO African Regional Office (AFRO) Library. The study population includes all fetuses and newborns from ≥22 weeks of gestation (birth weight ≥500gm) to 7 days after birth, with reported causes or/and determinants as exposure, and perinatal mortality (stillbirths and/or early neonatal deaths) as an outcome. We will include studies from 2010 to 2022, and to facilitate the inclusion of up-to-date data, we will request recent data from ongoing surveillance in the region. To assess the quality of included studies, we will use the Joanna Briggs Institute quality assessment tool for observational and trial studies. We will analyze the data using STATA version 17 statistical software and assess heterogeneity and publication bias by Higgins' I 2 and funnel plot, respectively. This systematic review will search for published studies, and seek unpublished data, on the burden, causes, and risk factors of perinatal mortality in East Africa. Findings will be reported, and gaps in the evidence base identified, with recommendations, with the ultimate aim of reducing perinatal deaths. PROSPERO-CRD42021291719.

Youth Experiencing Parental Death Due to Drug Poisoning and Firearm Violence in the US, 1999-2020

Youth (those aged <18 years) parental death has been associated with negative health outcomes. Understanding the burden of parental death due to drug poisoning (herein, drugs) and firearms is essential for informing interventions. To estimate the incidence of youth parental death due to drugs, firearms, and all other causes. This cross-sectional observational study was conducted using vital registration, including all US decedents, and census data from January 1990 through December 2020. Data were analyzed from May 30, 2023, to March 28, 2024. Parental death due to drug poisoning or firearms. A demographic matrix projection model was used to estimate the number and incidence of youth experiencing parental death, defined as the death of 1 or more parents, per 1000 population aged less than 18 years. Analyses evaluated parental deaths by drugs, firearms, and all other causes from 1999 through 2020 by race and ethnicity. Between 1999 and 2020, there were 931 785 drug poisoning deaths and 736 779 firearm-related deaths with a mean (SD) age of 42.6 (16.3) years. Most deaths occurred among males (73.8%) and White decedents (70.8%) followed by Black (17.5%) and Hispanic (9.5%) decedents. An estimated 759 000 (95% CI, 722 000-800 000) youth experienced parental death due to drugs and an estimated 434 000 (95% CI, 409 000-460 000) youth experienced parental death due to firearms, accounting for 17% of all parental deaths. From 1999 to 2020, the estimated number of youth who experienced parental death increased 345% (95% CI, 334%-361%) due to drugs and 39% (95% CI, 37%-41%) due to firearms compared with 24% (95% CI, 23%-25%) due to all other causes. Black youth experienced a disproportionate burden of parental deaths, based primarily on firearm deaths among fathers. In 2020, drugs and firearms accounted for 23% of all parental deaths, double the proportion in 1999 (12%). Results of this modeling study suggest that US youth are at high and increasing risk of experiencing parental death by drugs or firearms. Efforts to stem this problem should prioritize averting drug overdoses and firearm violence, especially among structurally marginalized groups.

Epidemiology and demographic patterns of cardiovascular diseases and neoplasms deaths in Western Europe: a 1990–2019 analysis

ObjectivesCardiovascular diseases (CVDs) and neoplasms have been considered as public health concerns worldwide. This study aimed to estimate the epidemiological patterns of death burden on CVDs and neoplasms and its attributable risk factors in Western Europe from 1990 to 2019 to discuss the potential causes of the disparities. Study design and methodsWe collected data on CVDs and neoplasms deaths in 24 Western European countries from the Global Burden of Disease Study. We analyzed patterns by age, sex, country, and associated risk factors. The results include percentages of total deaths, age-standardized death rates per 100,000 population, and uncertainty intervals (UIs). Time trends were assessed using annual percent change. ResultsIn 2019, CVDs and neoplasms accounted for 33.54% and 30.15% of Western Europe's total deaths, with age-standardized death rates of 128.05 (95% UI: 135.37, 113.02) and 137.51 (95% UI: 142.54, 128.01) per 100,000. Over 1990–2019, CVDs rates decreased by 54.97%, and neoplasms rates decreased by 19.54%. Top CVDs subtypes were ischemic heart disease and stroke; top cancers for neoplasms were lung and colorectal. Highest CVD death burdens were in Finland, Greece, Austria; neoplasm burdens in Monaco, San Marino, Andorra. The major risk factors were metabolic (CVDs) and behavioral (neoplasms). Gender differences revealed higher CVDs death burden in males, while neoplasms burden varied by risk factors and age groups. ConclusionIn 2019, CVDs and neoplasms posed significant health risks in Western Europe, with variations in death burdens and risk factors across genders, age groups, and countries. Future interventions should target vulnerable groups to lessen the impact of CVDs and neoplasms in the region.

Emerging Strategies and Effective Prevention Measures for Investigating the Association Between Stroke and Sudden Cardiac Fatality.

Stroke-related cardiac death is a significant concern for patients with stroke and their healthcare providers. It is a complex and multifaceted condition that requires careful management of both modifiable and non-modifiable risk factors. This review provides an overview of the pathophysiology, risk factors, and prevention strategies for stroke-related cardiac death. The review highlights the importance of identifying and managing modifiable risk factors such as hypertension, diabetes, and lifestyle factors, as well as non-modifiable risk factors such as age and genetics. Additionally, the review explores emerging strategies for prevention, including the use of wearable devices and genetic testing to identify patients at risk, stem cell therapy and gene therapy for cardiac dysfunction, and precision medicine for personalized treatment plans. Despite some limitations to this review, it provides valuable insights into the current understanding of stroke-related cardiac death and identifies important areas for future research. Ultimately, the implementation of evidence-based prevention strategies and personalized treatment plans has the potential to improve outcomes for patients with stroke and reduce the burden of stroke-related cardiac death in the population.

Impact of Social Vulnerability on Cardiac Arrest Mortality in the United States, 2016 to 2020.

Cardiac arrest is 1 of the leading causes of morbidity and mortality, with an estimated 340 000 out-of-hospital and 292 000 in-hospital cardiac arrest events per year in the United States. Survival rates are lower in certain racial and socioeconomic groups. We performed a county-level cross-sectional longitudinal study using the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research multiple causes of death data set between 2016 and 2020 among individuals of all ages whose death was attributed to cardiac arrest. The Social Vulnerability Index is a composite measure that includes socioeconomic vulnerability, household composition, disability, individuals from racial and ethnic minority groups status and language, and housing and transportation domains. We examined the impact of social determinants on cardiac arrest mortality stratified by age, race, ethnicity, and sex in the United States. All age-adjusted mortality rate (cardiac arrest AAMRs) are reported as per 100 000. Overall cardiac arrest AAMR during the study period was 95.6. The cardiac arrest AAMR was higher for men compared with women (119.6 versus 89.9) and for the Black population compared with the White population (150.4 versus 92.3). The cardiac arrest AAMR increased from 64.8 in counties in quintile 1 of Social Vulnerability Index to 141 in quintile 5, with an average increase of 13% (95% CI, 9.8%-16.9%) in AAMR per quintile increase. Mortality from cardiac arrest varies widely, with a >2-fold difference between the counties with the highest and lowest social vulnerability, highlighting the differential burden of cardiac arrest deaths throughout the United States based on social determinants of health.

Computed tomography benefits and cost in hemodynamically stable patients with blunt abdominal trauma at an Egyptian University Hospital

BackgroundTrauma is a significant cause of mortality, especially among individuals aged between 15 and 44 years, with a substantial burden falling on economically active populations. Low- and middle-income countries (LMICs) bear the burden of trauma-related deaths, accounting for over 90 % globally. In Egypt, trauma rates are increasing, primarily due to road traffic crashes (RTC), affecting males disproportionately. Blunt abdominal trauma, often caused by RTC, can lead to missed intra-abdominal injuries (IAIs) due to atypical symptoms. Computed Tomography (CT) offers high sensitivity and specificity in detecting IAIs, but concerns about cost and radiation exposure exist. MethodologyThis study investigates the roles of Focused Assessment with Sonography for Trauma (FAST) and CT in managing blunt abdominal trauma. A retrospective cohort study was conducted on hemodynamically stable patients. Data included patient demographics, trauma details, healthcare decisions, costs, and outcomes. ResultsComputed tomography significantly reduced unnecessary laparotomies (12.3% vs. 24.8 %, p = 0.001), shortened hospital stays (4.83±0.71 days vs. 6.15±1.28 days, p = 0.005), and reduced ICU admissions (8 vs. 32, p = 0.023) compared to FAST alone. Overall costs were lower in the CT & FAST Group ($2055.95 vs. $3488.7, p = 0.0001), with no significant difference in missed IAIs. ConclusionThis study highlights the limitations of relying solely on FAST for IAIs and underscores the value of CT in guiding healthcare decisions. Incorporating CT led to reduced negative laparotomies, shorter hospital stays, and fewer ICU admissions. While CT incurs initial costs, its long-term benefits outweigh expenditures, particularly in LMICs. This study provides insights into optimizing diagnostic approaches for blunt abdominal trauma in low-resource settings.
