RESUMO
Climate change is the number one threat to child health according to the World Health Organisation. It increases existing inequalities, and lower-income countries are disproportionately affected. This is unjust. Higher-income countries have contributed and continue to contribute more to climate change than lower-income countries. This has been recognised by the United Nations Committee on the Rights of the Child, which has ruled that states can be held responsible if their carbon emissions harm child rights both within and outside their jurisdiction. Nevertheless, there are few analyses of the bilateral relationship between higher- and lower-income countries concerning climate change. This article uses the UK and Malawi as a case study to illustrate higher-income countries' impact on child health in lower-income countries. It aims to assist higher-income countries in developing more targeted policies. Children in Malawi can expect more food insecurity and reduced access to clean water, sanitation, and education. They will be more exposed to heat stress, droughts, floods, air pollution and life-threatening diseases, such as malaria. In 2019, 5,000 Malawian children died from air pollution (17% of under-five deaths). The UK needs to pay its 'fair share' of climate finance and ensure adaptation is prioritised for lower-income countries. It can advocate for more equitable and transparent allocation of climate finance to support the most vulnerable countries. Additionally, the UK can act domestically to curtail revenue losses in Malawi and other lower-income countries, which would free up resources for adaptation. In terms of mitigation, the UK must increase its nationally determined commitments by 58% to reach net zero and include overseas emissions. Land use, heating systems and renewable energy must be reviewed. It must mandate comprehensive scope three emission reporting for companies to include impacts along their value chain, and support businesses, multinational corporations, and banks to reach net zero.
RESUMO
BACKGROUND: Nearly all countries have ratified the United Nations Convention on the Rights of the Child and, therefore, support children having access to their rights. However, only a small minority of children worldwide have access to their environmental, economic, and social rights. The most recent global effort to address these deficits came in 2015, when the United Nations General Assembly agreed to a plan for a fairer and more sustainable future by 2030 and outlined the Sustainable Development Goals (SDGs). One remediable cause is the lack of revenue in many countries, which affects all SDGs. However, illicit financial flows from low-income to high-income countries, including international tax abuse, continue unabated. METHODS: Using the most recent estimates of tax abuse perpetuated by multinational companies and tax evasion through offshore wealth, and precise econometric modelling, we illustrate the potential regarding child rights (or progress towards the SDGs) if there was an increase in revenue equivalent to tax abuse in Malawi, a low-income country particularly vulnerable to climate change. The Government Revenue and Development Estimations model provides realistic estimates of government revenue changes in developmental outcomes. Using panel data on government revenue per capita, it models the impact of increased revenue on governance and SDG progress. RESULTS: If cross-border tax abuse and tax evasion were curtailed, the equivalent increase in government revenue in one country, Malawi, would be associated with 12,000 and 20,000 people having access to basic water and sanitation respectively each year. Each year, an additional 5000 children would attend school, 150 additional children would survive, and 10 mothers would survive childbirth. CONCLUSIONS: More children would access their economic and social rights if actions were taken to close the gap in global governance regarding taxation. We discuss the responsibility of duty bearers, the need for a global body to arbitrate and monitor international tax matters, and how the Government of Malawi could take further domestic action to mitigate the gaps in global governance and protect itself against illicit financial flows, including tax abuse.

Introduction: Adherence to Antiretroviral Treatment (ART) in children and adolescents living with HIV in low-resource settings is not extensively studied in large cohort studies including both adults and pediatric patients. We compared rates of virological suppression, adherence and defaulting among children, adolescents and adults attending a family ART clinic at Queen Elizabeth Central Hospital; a tertiary hospital situated in the southern region of Malawi. Methods: The study was longitudinal and made use of routinely collected data for all 27,229 clinic attendees. Clinical information obtained at routine clinical visits entered electronically since 2008 was extracted in February 2017. This data was used to ascertain differences across the different age groups. Logistic regression and Cox regression models were fitted to compare rates of Virological Suppression (VS), adherence, and defaulting, respectively. Results: Younger and older adolescents (ages 10-14 years and 15-19 years respectively) were less likely to achieve VS compared to adults in the final model AOR 0.4 (0.2-0.9, 95% CI) and AOR 0.2 (0.1-0.4, 95% CI) respectively. Young children (ages 0-4 years), older children (ages 5-9 years) and younger adolescents were less adherent to ART compared to adults AOR 0.1 (0.1-0.2, 95% CI), AOR 0.2 (0.1-0.3, 95% CI), and AOR 0.4 (0.3-0.5, 95% CI) respectively. Young adults and younger children had an increased likelihood of defaulting compared to adults. Conclusion: Poor performance on ART of children and adolescents highlights unaddressed challenges to adherence. Ongoing research to explore these potential barriers and possible interventions needs to be carried out. The adherence assessment methods used and strategies for improving it among children and adolescents need to be revised at the clinic.
RESUMO
BACKGROUND: The COVID-19 pandemic and the climate emergency threaten progress in reaching many of the Sustainable Development Goal (SDG) targets by 2030. The under-5 mortality and maternal mortality rates are well below the targets, and if we progress at the current pace, there is a high risk of not meeting the 2030 goals. Furthermore, the initial progress in the decline in child and maternal mortality since 1990 is likely to be eroded. Much of this progress has resulted from increased sanitation, drinking water, education, and health service coverage. The adequate provision of public services is possible if there is sufficient government funding. When governments have more income, they spend more on public services, which increases access to fundamental economic and social rights and, thus, contributes to the SDGs. One of the key drivers of government financing, taxation, constitutes 70% of government revenue in low- and lower-middle-income countries. Corporate income tax constitutes 18.8% of tax revenue in African countries compared to 10% of tax revenue in OECD countries. Therefore, it plays a critical role in SDG progress. This paper aims to quantify the contribution of one large taxpayer, that publishes their tax payments, (Vodafone Group Plc) on progress towards SDGs in six African countries. We use econometric modelling to estimate the impact of an increase in government revenue equivalent to Vodafone's average tax paid between 2007-2017. RESULTS: We find that government revenue equivalent to Vodafone's taxes made a significant contribution to progress in attaining selected SDGs. We found that the revenue equivalent to Vodafone's taxes allowed 966,188 people to access clean water and 1,371,972 people to access basic sanitation each year. Over the time period studied, 858,054 children spent an extra year in school and 54,275 children under five years and 3,655 mothers survived. In just one of these countries, Tanzania, the revenue equivalent to Vodafone's tax contribution allowed 174,121 people to access clean water and 223,586 to access sanitation each year. Over the time studied 187,023 children spent an additional year at school, 6,569 additional children under five and 625 additional mothers survived. CONCLUSIONS: These findings demonstrate that the reported contributions from a single multinational corporation drive SDG progress. Furthermore, it highlights the importance of transparent taxes and explores the responsibilities of global institutions, governments, investors, and multinational corporations.

OBJECTIVE: We undertook a systematic review of strategies adopted to scale up COVID-19 testing in countries across income levels to identify successful approaches and facilitate learning. METHODS: Scholarly articles in English from PubMed, Google scholar and Google search engine describing strategies used to increase COVID-19 testing in countries were reviewed. Deductive analysis to allocate relevant text from the reviewed publications/reports to the a priori themes was done. MAIN RESULTS: The review covered 32 countries, including 11 high-income, 2 upper-middle-income, 13 lower-middle-income and 6 low-income countries. Most low- and middle-income countries (LMICs) increased the number of laboratories available for testing and deployed sample collection and shipment to the available laboratories. The high-income countries (HICs) that is, South Korea, Germany, Singapore and USA developed molecular diagnostics with accompanying regulatory and legislative framework adjustments to ensure the rapid development and use of the tests. HICs like South Korea leveraged existing manufacturing systems to develop tests, while the LMICs leveraged existing national disease control programmes (HIV, tuberculosis, malaria) to increase testing. Continent-wide, African Centres for Disease Control and Prevention-led collaborations increased testing across most African countries through building capacity by providing testing kits and training. CONCLUSION: Strategies taken appear to reflect the existing systems or economies of scale that a particular country could leverage. LMICs, for example, drew on the infectious disease control programmes already in place to harness expertise and laboratory capacity for COVID-19 testing. There however might have been strategies adopted by other countries but were never published and thus did not appear anywhere in the searched databases.

INTRODUCTION: Climate change is exacerbating a pre-existing child rights crisis. Lower- (low- and lower-middle-) income countries have borne 99% of the disease burden from the crisis, of which children under five carry 90%. In response, much of the recent global policy efforts focus on climate action. However, unsustainable levels of debt and tax abuses are draining countries of crucial revenue to handle the crisis. Like the climate crisis, these are primarily facilitated by entities domiciled within higher- (upper-middle- and high-) income countries. This paper aims to review these revenue leaks in countries where children are at the greatest risk of climate change to identify opportunities to increase climate change resilience. METHODS: We compiled data on tax abuse, debt service and climate risk for all lower-income countries with available data to highlight the need for intervention at the global level. We used the Climate Change Risk Index (CCRI), developed by UNICEF. Additionally, we used figures for tax abuse and debt service as a percentage of government revenue. RESULTS: We present data on 62 lower-income countries with data on revenue losses, of which 55 have CCRI data. Forty-two of these 62 countries (67.7%) are at high risk of lost government revenues. Forty-one (74.5%) of the 55 countries with CCRI data are at high risk of climate change. Thirty-one countries with data on both (56.4%) are at high risk of both climate change and revenue losses. Most countries at high risk of both are located in sub-Saharan Africa. This shows that countries most in need of resources lose money to arguably preventable leaks in government revenue. DISCUSSION: Higher-income countries and global actors can adopt policies and practices to ensure that they do not contribute to human rights abuses in other countries. Highlighting the impact of a failing global economic model on children's economic and social rights and one which increases their vulnerability to the climate emergency could help drive the transition towards a model that prioritises human rights and the environment on which we all depend.

Governments generally provide the services that allow people to access the critical determinants of health: water, sanitation, and education. These are also Sustainable Development Goals and fundamental economic and social human rights. Studies show that governments spend more on public services and health determinants with more revenue. However, governments in low and lower-middle-income countries have small budgets, and tax abuse (avoidance and evasion) contributes to revenue leaks. Researchers have estimated that four countries enable more than half of global tax abuse. We used estimates on tax abuse with a model of the relationship between government revenue and the determinants of health to quantify the potential for progress towards the Sustainable Development Goals 3, 4, 5, and 6. The increase in government revenue equivalent to global tax abuses is associated with 36 million people having access to basic sanitation and 18 million having access to basic drinking water. Additionally, over a ten year period, this increase would be associated with over 600,000 children and almost 80,000 mothers surviving. Thus, curtailing tax abuses would significantly contribute to progress towards the Sustainable Development Goals. Countries that enable tax abuses must review and modify policies to ensure progress towards these goals.

OBJECTIVE: To compare estimated losses from international corporate tax avoidance in individual countries and domestic government health expenditure, with reference to the annual threshold of 86 United States dollars (US$) per capita required to achieve universal health coverage. METHODS: I obtained and compared estimates of international corporate tax avoidance and domestic government health expenditure for 2013. FINDINGS: Data were available for 100 countries: 24 low-, 28 lower-middle-, 21 upper-middle- and 27 high-income countries. Domestic government health expenditure was under US$ 86 per capita in all 24 low-income countries and in 24 of 28 lower-middle-income countries. International corporate tax lost per capita was higher than domestic government health expenditure in 19 low-income and 10 lower-middle-income countries. If the revenue lost to tax avoidance were recouped and allocated to the health sector, average annual government health expenditure could increase from US$ 8 to US$ 24 per capita in the low-income countries studied and from US$ 54 to US$ 91 per capita in the lower-middle-income countries. CONCLUSION: Recouping losses due to international corporate tax avoidance and allocating them to the health sector would help low- and lower-middle-income countries achieve universal health coverage, a target of sustainable development goal (SDG) 3. Tackling tax avoidance requires cooperation between the governments of all countries, multinational corporations and investors, including private individuals. International cooperation to improve domestic resource mobilization is the focus of SDG target 17.1.

Inequities have a profound impact on the health and development of children globally. While inequities are greatest in the world's poorest countries, even in rich nations poorer children have poorer health and developmental outcomes. From birth through childhood to adolescence, morbidity, mortality, growth and development are socially determined, resulting in the most disadvantaged having the highest risk of poor health outcomes. Inequities in childhood impact across the life course. We consider four categories of actions to promote equity: strengthening individuals, strengthening communities, improving living and working conditions, and promoting healthy macropolicies. Inequities can be reduced but action to reduce inequities requires political will. The International Society for Social Paediatrics and Child Health (ISSOP) calls on governments, policy makers, paediatricians and professionals working with children and their organisations to act to reduce child health inequity as a priority. ISSOP recommends the following: governments act to reduce child poverty; ensure rights of all children to healthcare, education and welfare are protected; basic health determinants such as adequate nutrition, clean water and sanitation are available to all children. Paediatric and child health organisations ensure that their members are informed of the impact of inequities on children's well-being and across the life course; include child health inequities in curricula for professionals in training; publish policy statements relevant to their country on child health inequities; advocate for evidence-based pro-equity interventions using a child rights perspective; advocate for affordable, accessible and quality healthcare for all children; promote research to monitor inequity as well as results of interventions in their child populations. Paediatricians and child health professionals be aware of the impact of social determinants of health on children under their care; ensure their clinical services are accessible and acceptable to all children and families within the constraints of their country's health services; engage in advocacy at community and national level.
RESUMO
Recent World Health Organization (WHO) guidelines recommend antiretroviral therapy (ART) for all HIV-infected people; previously CD4+ T lymphocyte quantification (CD4 count) or clinical staging determined eligibility for children ≥ 5 years old in low- and middle-income countries. We examined positive predictive value (PPV) of a rapid diagnostic test (RDT) algorithm and ART eligibility for hospitalized children with newly diagnosed HIV infection. We enrolled 363 hospitalized Malawian children age 2 months to 16 years with two serial positive HIV RDT from 2013 to 2015. Children aged ≤ 18 months whose nucleic acid testing was negative or unavailable were later excluded from the analysis (N = 16). If RNA PCR was undetectable, human immunodeficiency virus (HIV) enzyme immunoassay (EIA) and western blot (WB) were performed. Those with negative or discordant EIA and WB were considered HIV negative and excluded from further analysis (N = 6). ART eligibility was assessed using age, CD4 count, and clinical HIV stage. Among 150 patients with HIV RNA PCR results, 15 had undetectable HIV RNA. Of those, EIA and WB were positive in nine patients and negative or discordant in six patients. PPV of serial RDT was 90% versus RNA PCR alone and 96% versus combined RNA PCR, EIA, and WB. Of all patients aged ≥ 5 years, 8.9% were ineligible for ART under previous WHO guidelines. Improved HIV testing algorithms are needed for accurate diagnosis of HIV infection in children as prevalence of pediatric HIV declines. Universal treatment will significantly increase the numbers of older children who qualify for ART.

BACKGROUND: Pneumocystis jiroveci pneumonia (PJP) is the most common opportunistic infection in infants with vertically acquired HIV infection and the most common cause of death in HIV-infected infants. OBJECTIVES: To determine whether early administration of adjuvant corticosteroids in addition to standard treatment reduces mortality in infants with vertically acquired HIV and clinically diagnosed PJP when co-infection with cytomegalovirus and other pathogens cannot be excluded. METHODS: A double-blind placebo-controlled trial of adjuvant prednisolone treatment in HIV-exposed infants aged 2-6 months admitted to Queen Elizabeth Central Hospital, Blantyre who were diagnosed clinically with PJP was performed. All recruited infants were HIV-exposed, and the HIV status of the infant was confirmed by DNA-PCR. HIV-exposed and infected infants as well as HIV-exposed but non-infected infants were included in the study. The protocol provided for the addition of prednisolone to the treatment at 48 h if there was clinical deterioration or an independent indication for corticosteroid therapy in any patient not receiving it. Oral trimethoprim-sulfamethoxazole (TMP/SMX) therapy and full supportive treatment were provided according to established guidelines. Primary outcomes for all patients included survival to hospital discharge and 6-month post-discharge survival. RESULTS: It was planned to enroll 200 patients but the trial was stopped early because of recruitment difficulties and a statistically significant result on interim analysis. Seventy-eight infants were enrolled between April 2012 and August 2014; 36 infants (46%) were randomised to receive corticosteroids plus standard treatment with TMP/SMX, and 42 infants (54%) received the standard treatment plus placebo. In an intention-to treat-analysis, the risk ratio of in-hospital mortality in the steroid group compared with the standard treatment plus placebo group was 0.53 [95% CI 0.29-0.97, p = 0.038]. The risk ratio of mortality at 6 months was 0.63 (95% CI 0.41-0.95, p = 0.029). Two children who received steroids developed bloody stools while in hospital. CONCLUSION: In infants with a clinical diagnosis of PJP, early use of steroids in addition to conventional TMP/SMX therapy significantly reduced mortality in hospital and 6 months after discharge.

Background: Provider initiated testing and counselling (PITC) is recommended for all inpatients in Malawi if they have not been tested in the previous 3 months. However testing rates remain low among children. We audited the effect of implementing a bedside diagnostic HIV testing service to determine if it would improve testing rates amongst paediatric inpatients. Methods: We audited the existing HIV testing service to determine the numbers of children being tested for HIV. This was followed by the introduction of a bedside diagnostic service followed by re-audit. Bedside testing was facilitated by health systems strengthening measures including identification of suitable counsellors, appropriate supervision and remuneration. Results: In the initial audit in March-April 2014, 85 (63%) of 135 children had documented HIV tests.. Following implementation of the bedside HIV testing service, there was a significant increase in the proportion of children whose HIV status was known. On re-audit in July 2015, 110 (94.8%) of 116 children had documented HIV tests (p<0.001). Of those with documented tests, 94.5% had been tested within the last 3-months compared to 61% in 2014. Following the introduction of the service, the proportion of children tested for HIV during admission increased from 31.9% to 68.1% (p<0.001). Conclusions: Implementation of a bedside testing service at Queen Elizabeth Central Hospital significantly increased HIV testing among paediatric inpatients. This has important implications in establishing earlier treatment, reducing HIV-associated morbidity and mortality.

BACKGROUND: The Committee on Economic, Social and Cultural Rights states that the right to health is closely related to, and dependent upon, the realization of other human rights, including the right to food, water, education and shelter which are important determinants of health. Children's healthcare workers in low income settings may spend the majority of their professional lives trying to mitigate deficiencies of these rights but have little influence over them. In order to advocate successfully at a local level, we should be aware of the proportion of children living in our catchment population who do not have access to their basic rights. In order to carry out a rights audit, a framework within which healthcare workers could play their part is required, as is an agreed minimum core of rights, a timeframe and a set of indicators. DISCUSSION: A framework to assess how well states and their developmental partners are adhering to human rights principles is discussed, including the role that a healthcare worker might optimally play. A minimum core of economic and social rights seeks to establish a legal minimum set of protections, which should be available with immediate effect and applicable to all nations despite very different resources. Minimum core rights and the impact that progressive realisation may have had on the right to health is discussed, including what they should include from the perspective of children's health. A set of absolute rights are suggested, based on physiological needs and aligned with the corresponding articles of the United Nations Convention on the Rights of the Child. The development indicators which are likely to be used to monitor progress towards the Sustainable Development Goals is suggested as a way to monitor rights. We consider the ways in which the healthcare worker could use a rights audit to advocate with, and for their community. These audits could achieve several objectives. They may legitimise healthcare workers' interests in the determinants of health and, as they are often highly respected by their community, this may facilitate them to be agents for change at a local level. This may raise awareness on basic human rights and their importance to health and contribute to a needed change in mind-set from one of development needs to absolute rights. The results may catalyse colleagues to analyse further the upstream reasons why children, and the families in which they live, are not having their rights met.

BACKGROUND: Antiretroviral therapy (ART) has led to increased survival of children with vertically acquired human immunodeficiency virus infection. Significant morbidity arises from respiratory symptoms, but aetiology and pulmonary function abnormalities have not been systematically studied. METHODS: Human immunodeficiency virus-positive children aged 8-16 years were systematically recruited within clinics in Blantyre, Malawi. Clinical review, quality of life assessment, spirometry, and chest radiography were performed. RESULTS: One hundred sixty participants had a mean of age 11.1 (range, 8-16) years and 50.0% were female. Cough was present in 60 (37.5%) participants, and 55 (34.4%) had moderate or severe dyspnoea. Thirty-four (22.1%) participants had digital clubbing. Thirty-three (20.6%) participants were hypoxic at rest. One hundred eighteen (73.8%) of the children were receiving ART; median CD4 count was 698 cells/µL in these compared with 406 cells/µL in ART-naive individuals (P < .001). From 145 spirometry traces (90.6%), mean forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) were 1.06 and 0.89 standard deviations below predicted mean, respectively. Twenty-one (14.5%) traces demonstrated obstructive defects and 26 (17.9%) reduced FVC. Lung function abnormality was not associated with any clinical findings. Of the 51 individuals with abnormal lung function, the mean increase in FEV1 after salbutamol was 3.8% (95% confidence interval, 0.02-7.53). "Tramlines" and ring shadows were seen on chest radiographs in over half of cases. CONCLUSIONS: Symptoms of chronic lung disease were highly prevalent with 2 main clinical phenotypes: "cough" and "hypoxia". Lung function abnormalities are common, poorly responsive to bronchodilators, and apparent throughout the age range of our cohort. Pathological causes remain to be elucidated. Cough and hypoxic phenotypes could be a useful part of diagnostic algorithms if further validated.
