Mapping of global, regional and national incidence, mortality and mortality-to-incidence ratio of lung cancer in 2020 and 2050
AimLung cancer is the leading cause of cancer deaths worldwide. This study examines the current and future burden of lung cancer at global, regional, and national levels.MethodsThe estimates of lung cancer incident cases, deaths, and their age-standardized rates are drawn from GLOBOCAN 2020 for 21 regions and 185 countries. Mortality-to-incidence ratio (MIR) is considered as a proxy indicator of 5-year survival rates. Lung cancer burden in 2050 is projected using age-specific incidence and death rates in 2020.ResultsIn 2020, there were 2.21 million new cases and 1.8 million deaths due to lung cancer worldwide with age-standardized incidence rate (ASIR) of 22.4/100,000 (male: 31.5; female: 14.6) and age-standardized mortality rates (ASMR) of 18.0/100,000, (male: 25.9; female: 11.2/100,000). Global MIR of lung cancer was 0.82 (males 0.83; females: 0.79), varying from 0.59 (Japan) to 1.0 (Belize). Hungary had the highest age-standardized rates (ASIR: 50.1/100,000; ASMR: 42.4/100,000) and Nigeria (ASIR: 0.88; ASMR: 0.86) had the lowest age-standardized rates in 2020. Both ASIR and ASMR were positively correlated with country-level tobacco smoking prevalence and human development index (HDI), whereas MIR exhibited a negative correlation with HDI. As per our projections, there will be 3.8 million incident cases and 3.2 million deaths globally due to lung cancer in 2050.ConclusionWith close to 2 million cases and deaths already in 2020, lung cancer has already become a global public health threat. Even with current risk levels and age-specific rates, lung cancer annual cases are expected to reach 3.8 million in 2050. Until smoking prevalence is reduced and ambient air pollution levels are checked, particularly in low/medium HDI countries, the lung cancer epidemic will continue unfolding.

Global, regional, national burden of breast cancer in 185 countries: evidence from GLOBOCAN 2018
PurposeThis study aims to examine the burden of breast cancer in 185 countries in 2018.MethodsThe estimates of incidence, mortality, and prevalence of breast cancer were drawn from GLOBOCAN 2018. The overall burden of breast cancer was gauged using breast cancer burden index (BRCBI)—a novel index comprising age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR), mortality-to-incidence ratio (MIR), prevalence-to-incidence ratio (PIR), and prevalence-to-mortality ratio (PMR). The socioeconomic status of countries was measured using human development index (HDI)ResultsGlobally, breast cancer was responsible for an estimated 626,679 deaths at age-standardized rate of 13/100,000; there were 2.1 million cases diagnosed in 2018 at age-standardized rate of 46.3/100,000. The ASIR varied 22-fold from 5/100,000 (Bhutan) to 113.2/100,000 (Belgium). The ASMR varied 13-fold from 2.7/100,000 (Bhutan) to 36.9/100,000 (Fiji). The HDI exhibited a positive gradient with ASIR (r = 0.73), PIR (r = 0.98), and PMR (r = 0.85); with MIR, however, it exhibited a negative association (r = − 0.83). The BRCBI spanned from 0.70 in Somalia to 78.92 in South Korea and exhibited a positive association with HDI (r = 0.76). An additional 46,823 female lives in 2018 and a cumulative total of 333,304 lives could have been saved over 2013–2018, had countries performed as per their HDI.ConclusionsThe substantial burden of breast cancer in developing and low-resource economies calls for a holistic approach to cancer management and control that includes oncologic infrastructure to provide cost-effective screening, diagnostic, therapeutic, and palliative services, greater breast cancer awareness, and mitigation of risk factors.

Health and economic growth: Evidence from dynamic panel data of 143 years
This paper re-examines health-growth relationship using an unbalanced panel of 17 advanced economies for the period 1870-2013 and employs panel generalised method of moments estimator that takes care of endogeneity issues, which arise due to reverse causality. We utilise macroeconomic data corresponding to inflation, government expenditure, trade and schooling in sample countries that takes care of omitted variable bias in growth regression. With alternate model specifications, we show that population health proxied by life expectancy exert a positive and significant effect on both real income per capita as well as growth. Our results are in conformity with the existing empirical evidence on the relationship between health and economic growth, they, however, are more robust due to the presence of long-term data, appropriate econometric procedure and alternate model specifications. We also show a strong role of endogeneity in driving standard results in growth empirics. In addition to life expectancy, other constituent of human capital, education proxied by schooling is also positively associated with real per capita income. Policy implication that follows from this paper is that per capita income can be boosted through focussed policy attention on population health. The results, however, posit differing policy implications for advanced and developing economies.

Renewable energy for sustainable development in India: current status, future prospects, challenges, employment, and investment opportunities
The primary objective for deploying renewable energy in India is to advance economic development, improve energy security, improve access to energy, and mitigate climate change. Sustainable development is possible by use of sustainable energy and by ensuring access to affordable, reliable, sustainable, and modern energy for citizens. Strong government support and the increasingly opportune economic situation have pushed India to be one of the top leaders in the world’s most attractive renewable energy markets. The government has designed policies, programs, and a liberal environment to attract foreign investments to ramp up the country in the renewable energy market at a rapid rate. It is anticipated that the renewable energy sector can create a large number of domestic jobs over the following years. This paper aims to present significant achievements, prospects, projections, generation of electricity, as well as challenges and investment and employment opportunities due to the development of renewable energy in India. In this review, we have identified the various obstacles faced by the renewable sector. The recommendations based on the review outcomes will provide useful information for policymakers, innovators, project developers, investors, industries, associated stakeholders and departments, researchers, and scientists.

Evasive balancing
India has adopted the Indo-Pacific concept with uncharacteristic speed. This article examines India’s Indo-Pacific strategy, which evolved out of its earlier ‘Look East’ and ‘Act East’ policies but is much more focused on strategic concerns than on trade or connectivity. As such, the strategy is subset of its China policy, and includes contradictory elements of balancing China by building partnerships with the United States as well as with regional powers, while simultaneously pursuing a reassurance strategy to convince Beijing that India is not really balancing China. The combination of these contradictory elements is characterized as evasive balancing, which is a more useful concept than either pure balancing or hedging for understanding the policies of India and of many other countries in the region that are trying to manage China’s rise. However, reassurance strategies rarely work and the combination of balancing and reassurance is even less likely to be viable.
