Cancer is an emerging public health problem in sub-Saharan Africa due to population growth, ageing and westernisation of lifestyles. In this piece, we use data from Mozambique over a 50-year period to illustrate cancer epidemiological trends in low-income and middle-income countries to hypothesise ...potential circumstances and factors that could explain changes in cancer burden and to discuss surveillance weaknesses and potential improvements. This epidemiological transition deserves increasing policy attention.

Vitamin A deficiency is a risk factor for blindness and for mortality from measles and diarrhoea in children aged 6–59 months. We aimed to estimate trends in the prevalence of vitamin A defi ciency between 1991 and 2013 and its mortality burden in low-income and middle-income countries.
In recent years, high prices of pharmaceutical products have posed challenges in high- and low-income countries alike. In many instances, high prices of pharmaceutical products have led to significant financial hardship for individuals and negatively impacted on healthcare systems’ ability to prov...ide population-wide access to essential medicines.
Pharmaceutical pricing policies need to be carefully planned, carried out, and regularly checked and revised according to changing conditions. Strong, well-thought-out policies can guide well-informed and balanced decisions to achieve affordable access to essential health products.
This guideline replaces the 2015 WHO guideline on country pharmaceutical pricing policies, revised to reflect the growing body of literature since the last evidence review in 2010. This update also recognizes country experiences in managing the prices of pharmaceutical products.

People younger than 20 years comprise 35% of the global population and 40% of the global population of least-developed nations. The number of children - neonates, infants, children, and adolescents up to 19 years of age - who need pediatric palliative care (PPC) each year may be as high as 21 millio...n. Another study found that almost 2.5 million children die each year with serious health related suffering and that more than 98% of these children are in low- and middle-income countries (LMICs) (3). While estimates differ, there is no doubt that there is an enormous need for prevention and relief of suffering among children - for PPC.

Stewardship is defined as “the careful and responsible management of something entrusted to one’s care”. It was originally applied in the health-care setting as a tool for optimizing antimicrobial use, termed “antimicrobial stewardship” (AMS). Stewardship has since be...en applied in the context of governance of the health sector as a whole, taking responsibility for the health and well-being of the population and guiding health systems at the national and global level.

As the world population is growing and health care resources are in high demand the pressure on medical services is becoming higher. Developing countries are already at a crisis point in health care provision, and time demands a new approach in structuring medical resources. Primary care is t...he vital pillar for fundamental health care at community level and has been deemed as a cost-effective modality. In the West the primary care physician manages chronic medical conditions in communities and therefore reduces unnecessary hospital admissions. In the West, the primary care system is extremely well organised. Low-income countries must improve teaching, training and funding in primary care. In this article the urgent need for primary care is discussed in developing countries, and ways to minimise costs and improve clinical outcomes at community level.

The Programme identifies the essential services to be provided by the health, social services, police and justice sectors as well as guidelines for the coordination of essential services and the governance of coordination processes and mechanisms. Service delivery guidelines for the core elements of... each essential service have been identified to ensure the delivery of high-quality services, particularly for low- and middle-income countries, for women and girls experiencing violence. Taken together, these elements comprise the “Essential services package”.
The package comprises seven modules. Available in different languages

Providing financial protection to the population for larger health care expenses arising out of hospital-based care, has come forth as a crucial element in the attainment of Universal Health Coverage (UHC) through the recent health financing reforms of low-and middle-income countries (LMIC). Over th...e last decade, the state of Assam in India, in an effort to ensure equitable health care access, has formulated multiple health protection schemes at different points of time. This has resulted in several such schemas which have had their own objectives, designs, institutional setups, and governance mechanisms. Moreover, they have reportedly been operating in relative silos.

Background
The ambitious development agenda of the Sustainable Development Goals (SDGs) requires substantial investments across several sectors, including for SDG 3 (healthy lives and wellbeing). No estimates of the additional resources needed to strengthen comprehensive health service delivery to...wards the attainment of SDG 3 and universal health coverage in low-income and middle-income countries have been published.
Methods
We developed a framework for health systems strengthening, within which population-level and individual-level health service coverage is gradually scaled up over time. We developed projections for 67 low-income and middle-income countries from 2016 to 2030, representing 95% of the total population in low-income and middle-income countries. We considered four service delivery platforms, and modelled two scenarios with differing levels of ambition: a progress scenario, in which countries’ advancement towards global targets is constrained by their health system’s assumed absorptive capacity, and an ambitious scenario, in which most countries attain the global targets. We estimated the associated costs and health effects, including reduced prevalence of illness, lives saved, and increases in life expectancy. We projected available funding by country and year, taking into account economic growth and anticipated allocation towards the health sector, to allow for an analysis of affordability and financial sustainability.

Background: Cardiovascular disease (CVD), mainly heart attack and stroke, is the
leading cause of premature mortality in low and middle income countries (LMICs).
Identifying and managing individuals at high risk of CVD is an important strategy to prevent and control CVD, in addition to multisector...al population-based interventions to reduce CVD risk factors in the entire population.
Methods: We describe key public health considerations in identifying and managing individuals at high risk of CVD in LMICs.
Results: A main objective of any strategy to identify individuals at high CVD risk is to maximize the number of CVD events averted while minimizing the numbers of
individuals needing treatment. Scores estimating the total risk of CVD (e.g. ten-year risk of fatal and non-fatal CVD) are available for LMICs, and are based on the main CVD risk factors (history of CVD, age, sex, tobacco use, blood pressure, blood cholesterol and diabetes status). Opportunistic screening of CVD risk factors enables identification of persons with high CVD risk, but this strategy can be widely applied in low resource settings only if cost effective interventions are used (e.g. the WHO Package of Essential NCD interventions for primary health care in low resource settings package) and if treatment (generally for years) can be sustained, including continued availability ofaffordable medications and funding mechanisms that allow people to purchase medications without impoverishing them (e.g. universal access to health care). Thisalso emphasises the need to re-orient health systems in LMICs towards chronic diseases management.
Conclusion: The large burden of CVD in LMICs and the fact that persons with high
CVD can be identified and managed along cost-effective interventions mean that
health systems need to be structured in a way that encourages patient registration, opportunistic screening of CVD risk factors, efficient procedures for the management of chronic conditions (e.g. task sharing) and provision of affordable treatment for those with high CVD risk. The focus needs to be in primary care because that is where most of the population can access health care and because CVD programmes can be run effectively at this level.

More than 40% of the world population is 24 years old or younger, the vast majority of whom live in low- and lower middle–income countries. Globally, a quarter of disability-adjusted life years (DALYs) for mental disorders and substance abuse is borne by this age group and about 75% of mental diso...rders diagnosed in adulthood have their onset before the age of
24 years . Most children and young people in developing countries, however, do not have access to mental health care.

Many low- and middle-income countries (LMICs) are undergoing an epidemiological transition. With an improvement in socioeconomic conditions and an aging population, cardiovascular diseases (CVDs), like cardiac arrhythmias, are expected to increase in these countries. However, there are limited studi...es on the epidemiology and management of cardiac arrhythmias in LMICs. This review will highlight the unique challenges and opportunities that these countries face when managing cardiac arrhythmias.

Global cardiovascular disease (CVD) burden is high and rising, especially in low-income and middle-income countries (LMICs). Focussing on 45 LMICs, we aimed to determine (1) the adult population’s median 10-year predicted CVD risk, including its variation within countries by socio-demographic char...acteristics, and (2) the prevalence of self-reported blood pressure (BP) medication use among those with and without an indication for such medication as per World Health Organization (WHO) guidelines.

Heart failure is an important global health problem, and the associated public health and economic effect is increasing across all societies and geographies.
Epidemiological studies have estimated that there are more than 25 million patients with heart failure globally, and population-based studie...s from North America and Europe have estimated that 1–2% of people are living with heart failure. Factors such as ageing and expanding populations have contributed to increasing hospital admissions for heart failure.

Socioeconomic status is associated with differences in risk factors for cardiovascular disease incidence and outcomes, including mortality. However, it is unclear whether the associations between cardiovascular disease and common measures of socioeconomic status—wealth and education—differ among... high-income, middle-income, and low-income countries, and, if so, why these differences exist. We explored the association between education and household wealth and cardiovascular disease and mortality to assess which marker is the stronger predictor of outcomes, and examined whether any differences in cardiovascular disease by socioeconomic status parallel differences in risk factor levels or differences in management.

Non-communicable diseases (NCDs) pose a substantial threat to many health systems, especially in low-income and middle-income countries (LMICs) where they are already overstretched. In the past few decades, deaths from NCDs in LMICs have spiked, whereas numbers in high-income countries have stabilis...ed. Worryingly, a large proportion of deaths from NCDs (29%) in LMICs occur among people younger than 60 years compared with the proportion in high-income countries (13%). This finding has been attributed to poor access to effective and equitable health-care services in most LMICs. The threat of NCDs in LMICs was recognised by the UN 2011 High-Level Meeting, and is now featured in Sustainable Development Goal 3 in the form of reducing premature mortality from NCDs by one-third before 2030. Cardiovascular diseases (CVDs) are the leading cause of deaths from NCDs (ie, 48% of all NCDs deaths). Therefore, substantial reductions in CVDs will have a major impact on reducing the overall burden of NCDs globally. The good news is that most CVDs can be prevented by addressing the key underlying behavioural risk factors, such as physical inactivity, unhealthy diet, tobacco use, and harmful use of alcohol, through population-wide approaches. Among individuals with or at high risk of CVD, early detection and effective management with appropriate counselling and medicines can reduce cardiovascular deaths substantially.
The importance of effective treatment for CVD has been recognised in the Global NCD Action Plan 2013–20, for which one of the nine global targets is that at least 50% of eligible individuals should receive drug therapy and counselling to prevent heart attacks and strokes by 2025.5 Although admirable, this is a hard target to achieve given that secondary prevention strategies in LMICs are often unaffordable or unavailable.

The region of Latin America and the Caribbean (LAC) has high levels of income inequality and urbanization. This leaves a large percentage of the population exposed and vulnerable to infectious disease outbreaks (1). The COVID-19 outbreak occurred suddenly, within a complex economic, social and polit...ical context and at a time of low economic growth and high levels of informal labour. Structural challenges of poverty, deep inequality across different dimensions, and weak health and social protection systems exacerbated the region’s vulnerability to the pandemic

Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.

Demographic and epidemiological transitions are changing the age structure of the population and the most common diseases. Non-communicable respiratory diseases are an increasing problem at both ends of the age range in low-income and middle-income countries. In children, who represent a large propo...rtion of the total population, the increasing problem of asthma is a strain on health services. Improved survival of the older population is increasing the proportion of morbidity and mortality attributable to chronic lung diseases. Health services in low-resource countries are poorly adapted to treating chronic diseases. Designed to respond episodically to acute disease, almost all historical investment has focused on infectious diseases. Crucial to the successful management of chronic diseases is an infrastructure designed to support pro-active management, providing not only an accurate diagnosis, but also a secure supply of cost effective drugs at an affordable price. The absence of such an infrastructure in many countries and the market failure that makes drugs generally more expensive in low-resource regions means that many people with chronic non-communicable lung diseases are not given effective treatment. This has damaging economic consequences. The common causes of poor lung health in lowincome countries are not the same as those in richer countries, and there is a need to study why they are so common and how best to manage them.
