Assessment of Factors Responsible for Encroachment on Public Land in Ajoda New Town in Oyo State, Nigeria
Public land is crucial for the execution of developmental projects in many nations. However, studies have indicated that most of the time, public land is often being encroached. The issue of concern in this paper is: why do people encroach on public land? A contextual investigation approach was embraced for this study and residents of Ajoda New Town (ANT) - a scheme of Oyo State Government, Nigeria were involved as respondents to a structured questionnaire prepared on a five-point Likert scale format. Respondents were randomly selected, and, a total of 322 completed copies of the questionnaire were found valid for data analysis. The study employed Weighted Mean Score and Principal Component Analysis in determining the factors that led to the land encroachment in the community. Results indicate that faulty administrative/implementation, the hostile attitude of original settlers, and excessive land acquisition by the government are the major factors responsible for land encroachment in the study area. It was recommended that during the acquisition process, the government should imbibe the culture of acquiring a reasonable portion of land which will not be far more than what is required to avoid encroachment, and adequate compensation paid to the affected persons
Adequate Compensation as a Tool for Conflict Resolution in Oil-Polluted Wetlands of Niger Delta Region of Nigeria
Nigeria as a nation is battling with conflicts in virtually all geopolitical zones of the country. A major conflicting region is Niger Delta, where oil and gas resource of the nation domicile and this has become a major threat to the national development as well as the economic base of the nation. The conflict in Niger Delta has many dimensions to it and has given birth to unrepentant militant whose aim is to truncate the nation if their demands were not met. Although attempts have been made by the government at various levels as well as the multinational oil companies to address the problems emanating from the negative effect of oil and gas exploration, production and transportation in the region, the desired peace is yet to be fully realized. As part of the solution to the conflict in Niger Delta, this paper argued that adequate compensation to oil pollution victim is a right step in right direction. However, to arrive at such compensation value, there is need to review the legal framework, composition of heads of claim, as well as the procedural guide to the conduct of compensation valuation among the Nigerian Estate Surveyors and Valuers

Valuation of properties in close proximity to waste dumps sites: The Nigeria experience
The paper identified and evaluated the techniques used by Nigerian Estate Surveyors and Valuers in valuing properties close to waste dump sites. A random sample of 107 Estate Surveyors and Valuers were taken from a sampling frame of 228 for the administration of questionnaire out of which 99 were returned. The data was analysed using the percentile, mean score and One SampleĀ tātest. The results show that majority of the Estate Surveyors and Valuers were not aware of the existence of methodologies used for the valuation of environmentally contaminated properties. The result further showed that the Estate Surveyors and Valuers over value properties in close proximity to the waste dump sites using inappropriate methods. In view of these findings, the undergraduate and postāgraduate curricula in Estate Management in the tertiary institutions should be reviewed to incorporate the appropriate methods of valuation in use for environmentally contaminated properties and the Continuous Professional Development (CPD) programme for the practitioners should be tailored to addresses this area of deficiency.

Global age-sex-specific mortality, life expectancy, and population estimates in 204 countries and territories and 811 subnational locations, 1950ā2021, and the impact of the COVID-19 pandemic: a comprehensive demographic analysis for the Global Burden of Disease Study 2021
Background: Estimates of demographic metrics are crucial to assess levels and trends of population health outcomes. The profound impact of the COVID-19 pandemic on populations worldwide has underscored the need for timely estimates to understand this unprecedented event within the context of long-term population health trends. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 provides new demographic estimates for 204 countries and territories and 811 additional subnational locations from 1950 to 2021, with a particular emphasis on changes in mortality and life expectancy that occurred during the 2020ā21 COVID-19 pandemic period. Methods: 22 223 data sources from vital registration, sample registration, surveys, censuses, and other sources were used to estimate mortality, with a subset of these sources used exclusively to estimate excess mortality due to the COVID-19 pandemic. 2026 data sources were used for population estimation. Additional sources were used to estimate migration; the effects of the HIV epidemic; and demographic discontinuities due to conflicts, famines, natural disasters, and pandemics, which are used as inputs for estimating mortality and population. Spatiotemporal Gaussian process regression (ST-GPR) was used to generate under-5 mortality rates, which synthesised 30 763 location-years of vital registration and sample registration data, 1365 surveys and censuses, and 80 other sources. ST-GPR was also used to estimate adult mortality (between ages 15 and 59 years) based on information from 31 642 location-years of vital registration and sample registration data, 355 surveys and censuses, and 24 other sources. Estimates of child and adult mortality rates were then used to generate life tables with a relational model life table system. For countries with large HIV epidemics, life tables were adjusted using independent estimates of HIV-specific mortality generated via an epidemiological analysis of HIV prevalence surveys, antenatal clinic serosurveillance, and other data sources. Excess mortality due to the COVID-19 pandemic in 2020 and 2021 was determined by subtracting observed all-cause mortality (adjusted for late registration and mortality anomalies) from the mortality expected in the absence of the pandemic. Expected mortality was calculated based on historical trends using an ensemble of models. In location-years where all-cause mortality data were unavailable, we estimated excess mortality rates using a regression model with covariates pertaining to the pandemic. Population size was computed using a Bayesian hierarchical cohort component model. Life expectancy was calculated using age-specific mortality rates and standard demographic methods. Uncertainty intervals (UIs) were calculated for every metric using the 25th and 975th ordered values from a 1000-draw posterior distribution. Findings: Global all-cause mortality followed two distinct patterns over the study period: age-standardised mortality rates declined between 1950 and 2019 (a 62Ā·8% [95% UI 60Ā·5ā65Ā·1] decline), and increased during the COVID-19 pandemic period (2020ā21; 5Ā·1% [0Ā·9ā9Ā·6] increase). In contrast with the overall reverse in mortality trends during the pandemic period, child mortality continued to decline, with 4Ā·66 million (3Ā·98ā5Ā·50) global deaths in children younger than 5 years in 2021 compared with 5Ā·21 million (4Ā·50ā6Ā·01) in 2019. An estimated 131 million (126ā137) people died globally from all causes in 2020 and 2021 combined, of which 15Ā·9 million (14Ā·7ā17Ā·2) were due to the COVID-19 pandemic (measured by excess mortality, which includes deaths directly due to SARS-CoV-2 infection and those indirectly due to other social, economic, or behavioural changes associated with the pandemic). Excess mortality rates exceeded 150 deaths per 100 000 population during at least one year of the pandemic in 80 countries and territories, whereas 20 nations had a negative excess mortality rate in 2020 or 2021, indicating that all-cause mortality in these countries was lower during the pandemic than expected based on historical trends. Between 1950 and 2021, global life expectancy at birth increased by 22Ā·7 years (20Ā·8ā24Ā·8), from 49Ā·0 years (46Ā·7ā51Ā·3) to 71Ā·7 years (70Ā·9ā72Ā·5). Global life expectancy at birth declined by 1Ā·6 years (1Ā·0ā2Ā·2) between 2019 and 2021, reversing historical trends. An increase in life expectancy was only observed in 32 (15Ā·7%) of 204 countries and territories between 2019 and 2021. The global population reached 7Ā·89 billion (7Ā·67ā8Ā·13) people in 2021, by which time 56 of 204 countries and territories had peaked and subsequently populations have declined. The largest proportion of population growth between 2020 and 2021 was in sub-Saharan Africa (39Ā·5% [28Ā·4ā52Ā·7]) and south Asia (26Ā·3% [9Ā·0ā44Ā·7]). From 2000 to 2021, the ratio of the population aged 65 years and older to the population aged younger than 15 years increased in 188 (92Ā·2%) of 204 nations. Interpretation: Global adult mortality rates markedly increased during the COVID-19 pandemic in 2020 and 2021, reversing past decreasing trends, while child mortality rates continued to decline, albeit more slowly than in earlier years. Although COVID-19 had a substantial impact on many demographic indicators during the first 2 years of the pandemic, overall global health progress over the 72 years evaluated has been profound, with considerable improvements in mortality and life expectancy. Additionally, we observed a deceleration of global population growth since 2017, despite steady or increasing growth in lower-income countries, combined with a continued global shift of population age structures towards older ages. These demographic changes will likely present future challenges to health systems, economies, and societies. The comprehensive demographic estimates reported here will enable researchers, policy makers, health practitioners, and other key stakeholders to better understand and address the profound changes that have occurred in the global health landscape following the first 2 years of the COVID-19 pandemic, and longer-term trends beyond the pandemic
Burden of disease scenarios for 204 countries and territories, 2022ā2050: a forecasting analysis for the Global Burden of Disease Study 2021
Background: Future trends in disease burden and drivers of health are of great interest to policy makers and the public at large. This information can be used for policy and long-term health investment, planning, and prioritisation. We have expanded and improved upon previous forecasts produced as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) and provide a reference forecast (the most likely future), and alternative scenarios assessing disease burden trajectories if selected sets of risk factors were eliminated from current levels by 2050. Methods: Using forecasts of major drivers of health such as the Socio-demographic Index (SDI; a composite measure of lag-distributed income per capita, mean years of education, and total fertility under 25 years of age) and the full set of risk factor exposures captured by GBD, we provide cause-specific forecasts of mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) by age and sex from 2022 to 2050 for 204 countries and territories, 21 GBD regions, seven super-regions, and the world. All analyses were done at the cause-specific level so that only risk factors deemed causal by the GBD comparative risk assessment influenced future trajectories of mortality for each disease. Cause-specific mortality was modelled using mixed-effects models with SDI and time as the main covariates, and the combined impact of causal risk factors as an offset in the model. At the all-cause mortality level, we captured unexplained variation by modelling residuals with an autoregressive integrated moving average model with drift attenuation. These all-cause forecasts constrained the cause-specific forecasts at successively deeper levels of the GBD cause hierarchy using cascading mortality models, thus ensuring a robust estimate of cause-specific mortality. For non-fatal measures (eg, low back pain), incidence and prevalence were forecasted from mixed-effects models with SDI as the main covariate, and YLDs were computed from the resulting prevalence forecasts and average disability weights from GBD. Alternative future scenarios were constructed by replacing appropriate reference trajectories for risk factors with hypothetical trajectories of gradual elimination of risk factor exposure from current levels to 2050. The scenarios were constructed from various sets of risk factors: environmental risks (Safer Environment scenario), risks associated with communicable, maternal, neonatal, and nutritional diseases (CMNNs; Improved Childhood Nutrition and Vaccination scenario), risks associated with major non-communicable diseases (NCDs; Improved Behavioural and Metabolic Risks scenario), and the combined effects of these three scenarios. Using the Shared Socioeconomic Pathways climate scenarios SSP2-4.5 as reference and SSP1-1.9 as an optimistic alternative in the Safer Environment scenario, we accounted for climate change impact on health by using the most recent Intergovernmental Panel on Climate Change temperature forecasts and published trajectories of ambient air pollution for the same two scenarios. Life expectancy and healthy life expectancy were computed using standard methods. The forecasting framework includes computing the age-sex-specific future population for each location and separately for each scenario. 95% uncertainty intervals (UIs) for each individual future estimate were derived from the 2Ā·5th and 97Ā·5th percentiles of distributions generated from propagating 500 draws through the multistage computational pipeline. Findings: In the reference scenario forecast, global and super-regional life expectancy increased from 2022 to 2050, but improvement was at a slower pace than in the three decades preceding the COVID-19 pandemic (beginning in 2020). Gains in future life expectancy were forecasted to be greatest in super-regions with comparatively low life expectancies (such as sub-Saharan Africa) compared with super-regions with higher life expectancies (such as the high-income super-region), leading to a trend towards convergence in life expectancy across locations between now and 2050. At the super-region level, forecasted healthy life expectancy patterns were similar to those of life expectancies. Forecasts for the reference scenario found that health will improve in the coming decades, with all-cause age-standardised DALY rates decreasing in every GBD super-region. The total DALY burden measured in counts, however, will increase in every super-region, largely a function of population ageing and growth. We also forecasted that both DALY counts and age-standardised DALY rates will continue to shift from CMNNs to NCDs, with the most pronounced shifts occurring in sub-Saharan Africa (60Ā·1% [95% UI 56Ā·8ā63Ā·1] of DALYs were from CMNNs in 2022 compared with 35Ā·8% [31Ā·0ā45Ā·0] in 2050) and south Asia (31Ā·7% [29Ā·2ā34Ā·1] to 15Ā·5% [13Ā·7ā17Ā·5]). This shift is reflected in the leading global causes of DALYs, with the top four causes in 2050 being ischaemic heart disease, stroke, diabetes, and chronic obstructive pulmonary disease, compared with 2022, with ischaemic heart disease, neonatal disorders, stroke, and lower respiratory infections at the top. The global proportion of DALYs due to YLDs likewise increased from 33Ā·8% (27Ā·4ā40Ā·3) to 41Ā·1% (33Ā·9ā48Ā·1) from 2022 to 2050, demonstrating an important shift in overall disease burden towards morbidity and away from premature death. The largest shift of this kind was forecasted for sub-Saharan Africa, from 20Ā·1% (15Ā·6ā25Ā·3) of DALYs due to YLDs in 2022 to 35Ā·6% (26Ā·5ā43Ā·0) in 2050. In the assessment of alternative future scenarios, the combined effects of the scenarios (Safer Environment, Improved Childhood Nutrition and Vaccination, and Improved Behavioural and Metabolic Risks scenarios) demonstrated an important decrease in the global burden of DALYs in 2050 of 15Ā·4% (13Ā·5ā17Ā·5) compared with the reference scenario, with decreases across super-regions ranging from 10Ā·4% (9Ā·7ā11Ā·3) in the high-income super-region to 23Ā·9% (20Ā·7ā27Ā·3) in north Africa and the Middle East. The Safer Environment scenario had its largest decrease in sub-Saharan Africa (5Ā·2% [3Ā·5ā6Ā·8]), the Improved Behavioural and Metabolic Risks scenario in north Africa and the Middle East (23Ā·2% [20Ā·2ā26Ā·5]), and the Improved Nutrition and Vaccination scenario in sub-Saharan Africa (2Ā·0% [ā0Ā·6 to 3Ā·6]). Interpretation: Globally, life expectancy and age-standardised disease burden were forecasted to improve between 2022 and 2050, with the majority of the burden continuing to shift from CMNNs to NCDs. That said, continued progress on reducing the CMNN disease burden will be dependent on maintaining investment in and policy emphasis on CMNN disease prevention and treatment. Mostly due to growth and ageing of populations, the number of deaths and DALYs due to all causes combined will generally increase. By constructing alternative future scenarios wherein certain risk exposures are eliminated by 2050, we have shown that opportunities exist to substantially improve health outcomes in the future through concerted efforts to prevent exposure to well established risk factors and to expand access to key health interventions
Global age-sex-specific mortality, life expectancy, and population estimates in 204 countries and territories and 811 subnational locations, 1950ā2021, and the impact of the COVID-19 pandemic: a comprehensive demographic analysis for the Global Burden of Disease Study 2021
BACKGROUND: Estimates of demographic metrics are crucial to assess levels and trends of population health outcomes. The profound impact of the COVID-19 pandemic on populations worldwide has underscored the need for timely estimates to understand this unprecedented event within the context of long-term population health trends. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 provides new demographic estimates for 204 countries and territories and 811 additional subnational locations from 1950 to 2021, with a particular emphasis on changes in mortality and life expectancy that occurred during the 2020ā21 COVID-19 pandemic period. METHODS: 22ā223 data sources from vital registration, sample registration, surveys, censuses, and other sources were used to estimate mortality, with a subset of these sources used exclusively to estimate excess mortality due to the COVID-19 pandemic. 2026 data sources were used for population estimation. Additional sources were used to estimate migration; the effects of the HIV epidemic; and demographic discontinuities due to conflicts, famines, natural disasters, and pandemics, which are used as inputs for estimating mortality and population. Spatiotemporal Gaussian process regression (ST-GPR) was used to generate under-5 mortality rates, which synthesised 30ā763 location-years of vital registration and sample registration data, 1365 surveys and censuses, and 80 other sources. ST-GPR was also used to estimate adult mortality (between ages 15 and 59 years) based on information from 31ā642 location-years of vital registration and sample registration data, 355 surveys and censuses, and 24 other sources. Estimates of child and adult mortality rates were then used to generate life tables with a relational model life table system. For countries with large HIV epidemics, life tables were adjusted using independent estimates of HIV-specific mortality generated via an epidemiological analysis of HIV prevalence surveys, antenatal clinic serosurveillance, and other data sources. Excess mortality due to the COVID-19 pandemic in 2020 and 2021 was determined by subtracting observed all-cause mortality (adjusted for late registration and mortality anomalies) from the mortality expected in the absence of the pandemic. Expected mortality was calculated based on historical trends using an ensemble of models. In location-years where all-cause mortality data were unavailable, we estimated excess mortality rates using a regression model with covariates pertaining to the pandemic. Population size was computed using a Bayesian hierarchical cohort component model. Life expectancy was calculated using age-specific mortality rates and standard demographic methods. Uncertainty intervals (UIs) were calculated for every metric using the 25th and 975th ordered values from a 1000-draw posterior distribution. FINDINGS: Global all-cause mortality followed two distinct patterns over the study period: age-standardised mortality rates declined between 1950 and 2019 (a 62Ā·8% [95% UI 60Ā·5ā65Ā·1] decline), and increased during the COVID-19 pandemic period (2020ā21; 5Ā·1% [0Ā·9ā9Ā·6] increase). In contrast with the overall reverse in mortality trends during the pandemic period, child mortality continued to decline, with 4Ā·66 million (3Ā·98ā5Ā·50) global deaths in children younger than 5 years in 2021 compared with 5Ā·21 million (4Ā·50ā6Ā·01) in 2019. An estimated 131 million (126ā137) people died globally from all causes in 2020 and 2021 combined, of which 15Ā·9 million (14Ā·7ā17Ā·2) were due to the COVID-19 pandemic (measured by excess mortality, which includes deaths directly due to SARS-CoV-2 infection and those indirectly due to other social, economic, or behavioural changes associated with the pandemic). Excess mortality rates exceeded 150 deaths per 100ā000 population during at least one year of the pandemic in 80 countries and territories, whereas 20 nations had a negative excess mortality rate in 2020 or 2021, indicating that all-cause mortality in these countries was lower during the pandemic than expected based on historical trends. Between 1950 and 2021, global life expectancy at birth increased by 22Ā·7 years (20Ā·8ā24Ā·8), from 49Ā·0 years (46Ā·7ā51Ā·3) to 71Ā·7 years (70Ā·9ā72Ā·5). Global life expectancy at birth declined by 1Ā·6 years (1Ā·0ā2Ā·2) between 2019 and 2021, reversing historical trends. An increase in life expectancy was only observed in 32 (15Ā·7%) of 204 countries and territories between 2019 and 2021. The global population reached 7Ā·89 billion (7Ā·67ā8Ā·13) people in 2021, by which time 56 of 204 countries and territories had peaked and subsequently populations have declined. The largest proportion of population growth between 2020 and 2021 was in sub-Saharan Africa (39Ā·5% [28Ā·4ā52Ā·7]) and south Asia (26Ā·3% [9Ā·0ā44Ā·7]). From 2000 to 2021, the ratio of the population aged 65 years and older to the population aged younger than 15 years increased in 188 (92Ā·2%) of 204 nations. INTERPRETATION: Global adult mortality rates markedly increased during the COVID-19 pandemic in 2020 and 2021, reversing past decreasing trends, while child mortality rates continued to decline, albeit more slowly than in earlier years. Although COVID-19 had a substantial impact on many demographic indicators during the first 2 years of the pandemic, overall global health progress over the 72 years evaluated has been profound, with considerable improvements in mortality and life expectancy. Additionally, we observed a deceleration of global population growth since 2017, despite steady or increasing growth in lower-income countries, combined with a continued global shift of population age structures towards older ages. These demographic changes will likely present future challenges to health systems, economies, and societies. The comprehensive demographic estimates reported here will enable researchers, policy makers, health practitioners, and other key stakeholders to better understand and address the profound changes that have occurred in the global health landscape following the first 2 years of the COVID-19 pandemic, and longer-term trends beyond the pandemic.

Global incidence, prevalence, years lived with disability (YLDs), disability-adjusted life-years (DALYs), and healthy life expectancy (HALE) for 371 diseases and injuries in 204 countries and territories and 811 subnational locations, 1990ā2021: a systematic analysis for the Global Burden of Disease Study 2021
Background: Detailed, comprehensive, and timely reporting on population health by underlying causes of disability and premature death is crucial to understanding and responding to complex patterns of disease and injury burden over time and across age groups, sexes, and locations. The availability of disease burden estimates can promote evidence-based interventions that enable public health researchers, policy makers, and other professionals to implement strategies that can mitigate diseases. It can also facilitate more rigorous monitoring of progress towards national and international health targets, such as the Sustainable Development Goals. For three decades, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) has filled that need. A global network of collaborators contributed to the production of GBD 2021 by providing, reviewing, and analysing all available data. GBD estimates are updated routinely with additional data and refined analytical methods. GBD 2021 presents, for the first time, estimates of health loss due to the COVID-19 pandemic. Methods: The GBD 2021 disease and injury burden analysis estimated years lived with disability (YLDs), years of life lost (YLLs), disability-adjusted life-years (DALYs), and healthy life expectancy (HALE) for 371 diseases and injuries using 100 983 data sources. Data were extracted from vital registration systems, verbal autopsies, censuses, household surveys, disease-specific registries, health service contact data, and other sources. YLDs were calculated by multiplying cause-age-sex-location-year-specific prevalence of sequelae by their respective disability weights, for each disease and injury. YLLs were calculated by multiplying cause-age-sex-location-year-specific deaths by the standard life expectancy at the age that death occurred. DALYs were calculated by summing YLDs and YLLs. HALE estimates were produced using YLDs per capita and age-specific mortality rates by location, age, sex, year, and cause. 95% uncertainty intervals (UIs) were generated for all final estimates as the 2Ā·5th and 97Ā·5th percentiles values of 500 draws. Uncertainty was propagated at each step of the estimation process. Counts and age-standardised rates were calculated globally, for seven super-regions, 21 regions, 204 countries and territories (including 21 countries with subnational locations), and 811 subnational locations, from 1990 to 2021. Here we report data for 2010 to 2021 to highlight trends in disease burden over the past decade and through the first 2 years of the COVID-19 pandemic. Findings: Global DALYs increased from 2Ā·63 billion (95% UI 2Ā·44ā2Ā·85) in 2010 to 2Ā·88 billion (2Ā·64ā3Ā·15) in 2021 for all causes combined. Much of this increase in the number of DALYs was due to population growth and ageing, as indicated by a decrease in global age-standardised all-cause DALY rates of 14Ā·2% (95% UI 10Ā·7ā17Ā·3) between 2010 and 2019. Notably, however, this decrease in rates reversed during the first 2 years of the COVID-19 pandemic, with increases in global age-standardised all-cause DALY rates since 2019 of 4Ā·1% (1Ā·8ā6Ā·3) in 2020 and 7Ā·2% (4Ā·7ā10Ā·0) in 2021. In 2021, COVID-19 was the leading cause of DALYs globally (212Ā·0 million [198Ā·0ā234Ā·5] DALYs), followed by ischaemic heart disease (188Ā·3 million [176Ā·7ā198Ā·3]), neonatal disorders (186Ā·3 million [162Ā·3ā214Ā·9]), and stroke (160Ā·4 million [148Ā·0ā171Ā·7]). However, notable health gains were seen among other leading communicable, maternal, neonatal, and nutritional (CMNN) diseases. Globally between 2010 and 2021, the age-standardised DALY rates for HIV/AIDS decreased by 47Ā·8% (43Ā·3ā51Ā·7) and for diarrhoeal diseases decreased by 47Ā·0% (39Ā·9ā52Ā·9). Non-communicable diseases contributed 1Ā·73 billion (95% UI 1Ā·54ā1Ā·94) DALYs in 2021, with a decrease in age-standardised DALY rates since 2010 of 6Ā·4% (95% UI 3Ā·5ā9Ā·5). Between 2010 and 2021, among the 25 leading Level 3 causes, age-standardised DALY rates increased most substantially for anxiety disorders (16Ā·7% [14Ā·0ā19Ā·8]), depressive disorders (16Ā·4% [11Ā·9ā21Ā·3]), and diabetes (14Ā·0% [10Ā·0ā17Ā·4]). Age-standardised DALY rates due to injuries decreased globally by 24Ā·0% (20Ā·7ā27Ā·2) between 2010 and 2021, although improvements were not uniform across locations, ages, and sexes. Globally, HALE at birth improved slightly, from 61Ā·3 years (58Ā·6ā63Ā·6) in 2010 to 62Ā·2 years (59Ā·4ā64Ā·7) in 2021. However, despite this overall increase, HALE decreased by 2Ā·2% (1Ā·6ā2Ā·9) between 2019 and 2021. Interpretation: Putting the COVID-19 pandemic in the context of a mutually exclusive and collectively exhaustive list of causes of health loss is crucial to understanding its impact and ensuring that health funding and policy address needs at both local and global levels through cost-effective and evidence-based interventions. A global epidemiological transition remains underway. Our findings suggest that prioritising non-communicable disease prevention and treatment policies, as well as strengthening health systems, continues to be crucially important. The progress on reducing the burden of CMNN diseases must not stall; although global trends are improving, the burden of CMNN diseases remains unacceptably high. Evidence-based interventions will help save the lives of young children and mothers and improve the overall health and economic conditions of societies across the world. Governments and multilateral organisations should prioritise pandemic preparedness planning alongside efforts to reduce the burden of diseases and injuries that will strain resources in the coming decades.

Effects of antibiotic resistance, drug target attainment, bacterial pathogenicity and virulence, and antibiotic access and affordability on outcomes in neonatal sepsis: an international microbiology and drug evaluation prospective substudy (BARNARDS)
Background
Sepsis is a major contributor to neonatal mortality, particularly in low-income and middle-income countries (LMICs). WHO advocates ampicillināgentamicin as first-line therapy for the management of neonatal sepsis. In the BARNARDS observational cohort study of neonatal sepsis and antimicrobial resistance in LMICs, common sepsis pathogens were characterised via whole genome sequencing (WGS) and antimicrobial resistance profiles. In this substudy of BARNARDS, we aimed to assess the use and efficacy of empirical antibiotic therapies commonly used in LMICs for neonatal sepsis.
Methods
In BARNARDS, consenting motherāneonates aged 0ā60 days dyads were enrolled on delivery or neonatal presentation with suspected sepsis at 12 BARNARDS clinical sites in Bangladesh, Ethiopia, India, Pakistan, Nigeria, Rwanda, and South Africa. Stillborn babies were excluded from the study. Blood samples were collected from neonates presenting with clinical signs of sepsis, and WGS and minimum inhibitory concentrations for antibiotic treatment were determined for bacterial isolates from culture-confirmed sepsis. Neonatal outcome data were collected following enrolment until 60 days of life. Antibiotic usage and neonatal outcome data were assessed. Survival analyses were adjusted to take into account potential clinical confounding variables related to the birth and pathogen. Additionally, resistance profiles, pharmacokineticāpharmacodynamic probability of target attainment, and frequency of resistance (ie, resistance defined by in-vitro growth of isolates when challenged by antibiotics) were assessed. Questionnaires on health structures and antibiotic costs evaluated accessibility and affordability.
Findings
Between Nov 12, 2015, and Feb 1, 2018, 36ā285 neonates were enrolled into the main BARNARDS study, of whom 9874 had clinically diagnosed sepsis and 5749 had available antibiotic data. The four most commonly prescribed antibiotic combinations given to 4451 neonates (77Ā·42%) of 5749 were ampicillināgentamicin, ceftazidimeāamikacin, piperacillinātazobactamāamikacin, and amoxicillin clavulanateāamikacin. This dataset assessed 476 prescriptions for 442 neonates treated with one of these antibiotic combinations with WGS data (all BARNARDS countries were represented in this subset except India). Multiple pathogens were isolated, totalling 457 isolates. Reported mortality was lower for neonates treated with ceftazidimeāamikacin than for neonates treated with ampicillināgentamicin (hazard ratio [adjusted for clinical variables considered potential confounders to outcomes] 0Ā·32, 95% CI 0Ā·14ā0Ā·72; p=0Ā·0060). Of 390 Gram-negative isolates, 379 (97Ā·2%) were resistant to ampicillin and 274 (70Ā·3%) were resistant to gentamicin. Susceptibility of Gram-negative isolates to at least one antibiotic in a treatment combination was noted in 111 (28Ā·5%) to ampicillināgentamicin; 286 (73Ā·3%) to amoxicillin clavulanateāamikacin; 301 (77Ā·2%) to ceftazidimeāamikacin; and 312 (80Ā·0%) to piperacillinātazobactamāamikacin. A probability of target attainment of 80% or more was noted in 26 neonates (33Ā·7% [SD 0Ā·59]) of 78 with ampicillināgentamicin; 15 (68Ā·0% [3Ā·84]) of 27 with amoxicillin clavulanateāamikacin; 93 (92Ā·7% [0Ā·24]) of 109 with ceftazidimeāamikacin; and 70 (85Ā·3% [0Ā·47]) of 76 with piperacillinātazobactamāamikacin. However, antibiotic and country effects could not be distinguished. Frequency of resistance was recorded most frequently with fosfomycin (in 78 isolates [68Ā·4%] of 114), followed by colistin (55 isolates [57Ā·3%] of 96), and gentamicin (62 isolates [53Ā·0%] of 117). Sites in six of the seven countries (excluding South Africa) stated that the cost of antibiotics would influence treatment of neonatal sepsis
