Malaria is one of the world's most serious and complex health problems. It is also one of the diseases identified as most likely to be affected by climate change, because transmission is sensitive to temperature and rainfall. The objective of this paper is to provide an initial economic valuation of the increased incidence of malaria due to projected changes in climate in South Africa, excluding costs and benefits of prevention and adaptation. We use market based economic valuation tools for morbidity, including cost of treatment and lost short term productivity, and report lost disability adjusted life years from malaria mortality due to climate change. We also discuss how human capital and willingness to pay approaches could be used for mortality valuation. The results show that the opportunity cost of increased morbidity from malaria would be between R277 million and R466 million in 2010, while the lost disability adjusted life years from increased mortality would be from 11 800 to 18 300 years in that year.

Chapter 5 discusses the use of epidemiology to identify the source of public health problems and inform policymaking. It uses a case study to illustrate how researchers, policymakers, and practitioners detect diseases, identify their sources, determine the extent of an outbreak, and prevent new infections. The chapter also defines key measures in epidemiology that can indicate public health priorities, including morbidity and mortality, years of potential life lost, and measures of lifetime impacts, including disability-adjusted life years and quality-adjusted life years. Finally, the chapter reviews epidemiological study designs, differentiating between experimental and observational studies, to show how to interpret data and identify limitations.

Abstract Distributional economic evaluation estimates the value for money of health interventions in terms of population health and health equity impacts. When applied to interventions delivered at the population and health system-level interventions (PSIs) instead of clinical interventions, additional practical and methodological challenges arise. Using the example of the Programme Saúde da Familia (PSF) in Brazil, a community-level primary care system intervention, we seek to illustrate these challenges and provide potential solutions. We use a distributional cost-effectiveness analysis (DCEA) approach to evaluate the impact of the PSF on population health and between-state health inequalities in Brazil. Data on baseline health status, disease prevalence and PSF effectiveness are extracted from the literature and incorporated into a Markov model to estimate the long-term impacts in terms of disability-adjusted life years. The inequality and average health impacts are analysed simultaneously using health-related social welfare functions. Uncertainty is computed using Monte Carlo simulation. The DCEA encountered several challenges in the context of PSIs. Non-randomized, quasi-experimental methods may not be powered to identify treatment effect heterogeneity estimates to inform a decision model. PSIs are more likely to be funded from multiple public sector budgets, complicating the calculation of health opportunity costs. We estimate a cost-per-disability-adjusted life years of funding the PSF of $2640. Net benefits were positive across the likely range of intervention cost. Social welfare analysis indicates that, compared to gains in average health, changes in health inequalities accounted for a small proportion of the total welfare improvement, even at high levels of social inequality aversion. Evidence on the population health and health equity impacts of PSIs can be incorporated into economic evaluation methods, although with additional complexity and assumptions. The case study results indicate that the PSF is likely to be cost-effective but that the inequality impacts are small and highly uncertain.

To meet newly proposed bromate standards, ozone doses should be decreased, thus also decreasing the risk of renal cell cancer, but the risk of infection with Cryptosporidium parvum will increase at the same time. The present study was designed to evaluate and balance these two risks, using a probabilistic risk assessment, which involves calculating the disease burden, expressed in the number of disability adjusted life-years (DALY) as developed by Havelaar et al. In the case of Neuilly-sur-Marne ozone contactors, four ozone doses were studied at 5°C and at 22°C. Results showed a sharp decrease of the disease burden with the application of ozone, and then a slight increase as the ozone dose was increased. Minimal DALYs were obtained with ozone doses of 1.5 mg/L at 22°C and 2.5 mg/L at 5°C. Nevertheless, these two ozone doses do not comply with the 10 μg/L bromate standard, as an average of 12 at 5°C and 11 at 22°C are produced.

Climate change adaptation is receiving ever more attention in the literature and in practice. Since available funds are not meeting adaptation needs, the question of how to allocate scarce resources becomes pressing. Universal adaptation metrics promise to facilitate the allocation process ex ante and the evaluation of projects ex post. Two such metrics have been proposed recently: Saved Wealth (SW), measured in terms of money, and Saved Health (SH), gauged in terms of disability adjusted life-years (DALYs). The paper analyzes this SWSH approach and shows that it is replete with unresolved conceptual and normative-ethical problems, which are exemplary for universal metrics seeking to combine concerns for equity and efficiency at once. The paper’s aim is to uncover these issues, and its conclusion is modest: universal metrics such as SW and the DALY have to be designed and used with great caution and further research is necessary.

Malaria is one of the oldest chronic, most dreaded killer diseases. It is a protozoan Plasmodium borne disease which is transmitted in humans by very efficient mosquito Anopheles. Out of four plasmodium genus, vivax is more dominant and falciparum species likely to cause severe lethal malaria.According to WHO, malaria killed 627000 people in 2012, majority of them sub-Saharan African children under the age of 5. This preeminent tropical parasite disease is one of the top 3 killers among communicable diseases. It is the only vector borne disease to be placed on WHO- DALY’s (disability adjusted life years) list, as it affects the mortality and morbidity rate as well as economy of any country.

Life expectancy decreases with aging, with cardiovascular, mental health, and neurodegenerative disorders strongly contributing to the total disability-adjusted life years. Interestingly, the morbidity/mortality paradox points to females having a worse healthy life expectancy. Since bidirectional interactions between cardiovascular and Alzheimer’s diseases (AD) have been reported, the study of this emerging field is promising. In the present work, we further explored the cardiovascular–brain interactions in mice survivors of two cohorts of non-transgenic and 3xTg-AD mice, including both sexes, to investigate the frailty/survival through their life span. Survival, monitored from birth, showed exceptionally worse mortality rates in females than males, independently of the genotype. This mortality selection provided a “survivors” cohort that could unveil brain–cardiovascular interaction mechanisms relevant for normal and neurodegenerative aging processes restricted to long-lived animals. The results show sex-dependent distinct physical (worse in 3xTg-AD males), neuropsychiatric-like and cognitive phenotypes (worse in 3xTg-AD females), and hypothalamic–pituitary–adrenal (HPA) axis activation (higher in females), with higher cerebral blood flow and improved cardiovascular phenotype in 3xTg-AD female mice survivors. The present study provides an experimental scenario to study the suggested potential compensatory hemodynamic mechanisms in end-of-life dementia, which is sex-dependent and can be a target for pharmacological and non-pharmacological interventions.

Abstract Background This study presents an up-to-date, comprehensive and comparative examination of breast cancer’s temporal patterns in females in Asia in last three decades. Methods The estimates of incidence, mortality, disability-adjusted-life-years and risk factors of breast cancer in females in 49 Asian countries were retrieved from Global Burden of Disease 2019 study. Results In Asia, female breast cancer incidence grew from 245 045[226 259–265 260] in 1990 to 914 878[815 789–1025 502] in 2019 with age-standardized incidence rate rising from 21.2/100 000[19.6–22.9] to 35.9/100 000[32.0–40.2] between 1990 and 2019. The death counts more than doubled from 136 665[126 094–148 380] to 337 822[301 454–375 251]. The age-standardized mortality rate rose marginally between 1990 and 2019 (1990: 12.1[11.0–13.1]; 2019: 13.4[12.0–14.9]). In 2019, age-standardized incidence rate varied from 17.2/100 000[13.95–21.4] in Mongolia to 122.5[92.1–160.7] in Lebanon and the age-standardized mortality rate varied 4-fold from 8.0/100 000 [7.2–8.8] in South Korea to 51.9[39.0–69.8] in Pakistan. High body mass index (5.6%), high fasting plasma glucose (5.6%) and secondhand smoke (3.5%) were the main contributory risk factors to all-age disability-adjusted-life-years due to breast cancer in Asia. Conclusion With growing incidence, escalating dietary and behavioural risk factors and lower survival rates due to late-disease presentation in low- and medium-income countries of Asia, breast cancer has become a significant public health threat. Its rising burden calls for increasing breast cancer awareness, preventive measures, early-stage detection and cost-effective therapeutics in Asia.

To describe the trends of HIV/AIDS metrics related to the burden of disease for Brazil between 1990 and 2017 we conducted a timeseries analysis for HIV/AIDS indicators by extracting data from the Global Burden of Disease study. We calculated traditional prevalence, incidence and mortality rates, the number of years lost by HIV-related deaths (YLL) and disability (YLD), and disability-adjusted life years (DALY). We estimated time series models and assessed the impact of highly active antiretroviral therapy (HAART) on the same indicators. In the set of disability-adjusted life years (DALY), the highest weight of its magnitude was due to YLL. There was a decline, especially after 1996, of DALY, mortality and YLL for HIV/AIDS. However, YLD, incidence, and prevalence increased over the same period. Also, the analysis of interrupted time series showed that the introduction of HAART into health policy had a significant impact on indicators, especially for DALY and YLL. We need to assess the quality of life of people living with HIV, especially among older adults. In addition, we need to focus on primary prevention, emphasizing methods to avoid infection and public policies should reflect this.

Myanmar is home to over 51 million people. The age- and sex-standardized mortality rate due to stroke is 165.4/100,000, while the rate of age- and sex-standardized disability-adjusted life years lost due to stroke is 2971.3/100,000. The prevalence of stroke among adults aged 40–99 years is 1.5%. Stroke is the leading cause of morbidity and mortality and comprises 20% of the neurological workload. There are only 10 stroke units in the whole country. Doctors are aware of the importance of hypertension in stroke prevention and the need for physiotherapy after stroke, but, until recently and in rural areas, they also tend to use steroids and neuroprotectants, and lower blood pressure aggressively acutely after stroke; antiplatelets are not widely used. Thrombolysis service is available at some tertiary centers but mechanical thrombectomy is not yet available.
