RESUMO

INTRODUCTION: Approximately 33 million people suffer catastrophic health expenditure (CHE) from surgery and/or anesthesia costs. The aim of this systematic review is to evaluate catastrophic and impoverishing expenditure associated with surgery and anesthesia in low- and middle-income countries (LMICs). METHODS: We performed a systematic review of all studies from 1990 to 2021 that reported CHE in LMICs for treatment of a condition requiring surgical intervention, including cesarean section, trauma care, and other surgery. RESULTS: 77 studies met inclusion criteria. Tertiary facilities (23.4%) were the most frequently studied facility type. Only 11.7% of studies were conducted in exclusively rural health-care settings. Almost 60% of studies were retrospective in nature. The cost of procedures ranged widely, from $26 USD for a cesarean section in Mauritania in 2020 to $74,420 for a pancreaticoduodenectomy in India in 2018. GDP per capita had a narrower range from $315 USD in Malawi in 2019 to $9955 USD in Malaysia in 2015 (Median = $1605.50, interquartile range = $1208.74). 35 studies discussed interventions to reduce cost and catastrophic expenditure. Four of those studies stated that their intervention was not successful, 18 had an unknown or equivocal effect on cost and CHE, and 13 concluded that their intervention did help reduce cost and CHE. CONCLUSIONS: CHE from surgery is a worldwide problem that most acutely affects vulnerable patients in LMICs. Existing efforts are insufficient to meet the true need for affordable surgical care unless assistance for ancillary costs is given to patients and families most at risk from CHE.

RESUMO

Although radiotherapy continues to evolve as a mainstay of the oncological armamentarium, research and innovation in radiotherapy in low-income and middle-income countries (LMICs) faces challenges. This third Series paper examines the current state of LMIC radiotherapy research and provides new data from a 2022 survey undertaken by the International Atomic Energy Agency and new data on funding. In the context of LMIC-related challenges and impediments, we explore several developments and advances-such as deep phenotyping, real-time targeting, and artificial intelligence-to flag specific opportunities with applicability and relevance for resource-constrained settings. Given the pressing nature of cancer in LMICs, we also highlight some best practices and address the broader need to develop the research workforce of the future. This Series paper thereby serves as a resource for radiation professionals.

RESUMO

Growth faltering in children (low length for age or low weight for length) during the first 1,000 days of life (from conception to 2 years of age) influences short-term and long-term health and survival1,2. Interventions such as nutritional supplementation during pregnancy and the postnatal period could help prevent growth faltering, but programmatic action has been insufficient to eliminate the high burden of stunting and wasting in low- and middle-income countries. Identification of age windows and population subgroups on which to focus will benefit future preventive efforts. Here we use a population intervention effects analysis of 33 longitudinal cohorts (83,671 children, 662,763 measurements) and 30 separate exposures to show that improving maternal anthropometry and child condition at birth accounted for population increases in length-for-age z-scores of up to 0.40 and weight-for-length z-scores of up to 0.15 by 24 months of age. Boys had consistently higher risk of all forms of growth faltering than girls. Early postnatal growth faltering predisposed children to subsequent and persistent growth faltering. Children with multiple growth deficits exhibited higher mortality rates from birth to 2 years of age than children without growth deficits (hazard ratios 1.9 to 8.7). The importance of prenatal causes and severe consequences for children who experienced early growth faltering support a focus on pre-conception and pregnancy as a key opportunity for new preventive interventions.

RESUMO

Delivering urological humanitarian aid to countries with greater need has been provided by urologists associated with British Association of Urological Surgeons (BAUS) Urolink over the last 30 years. Urolink has realised the need to understand where that need is geographically, what tangible help is required, and how assistance can be delivered in the most ethically appropriate way. The World Bank stratification of countries by per capita gross national income has helped in the identification of low-come countries or lower-middle-income countries (LMICs), the vast majority of which are in sub-Saharan Africa. The medical and socioeconomic needs of those country's populations, which constitute 17% of the global community, are substantially different from that required in higher income countries. More than 40% of sub-Saharan Africa's population is aged <14 years, it has a substantially reduced life expectancy, which influences the type of pathologies seen, and perinatal complications are a major cause of morbidity for both mother and child. There is a significant problem with the availability of medical care in these countries and almost a third of global deaths have been attributed to the lack of access to emergency and elective surgery. Urologically, the main conditions demanding the attention of the very few available urologists are congenital anomalies, benign prostatic hypertrophy, urolithiasis, urethral stricture, and pelvic cancer. The management of these conditions is often substantially different from that in the UK, being limited by a lack of personnel, equipment, and access to geographically relevant guidelines appropriate to the healthcare environment. Assisting LMICs to develop sustainable urological services can be helped by understanding the local needs of linked institutions, establishing trusting and durable relationships with partner centres and by providing appropriate education that can be perpetuated, and disseminated, across a region of need.

RESUMO

BACKGROUND: As the prevalence of hypercholesterolemia is increasing in low- and middle-income countries (LMICs), detailed evidence is urgently needed to guide the response of health systems to this epidemic. This study sought to quantify unmet need for hypercholesterolemia care among adults in 35 LMICs. METHODS AND FINDINGS: We pooled individual-level data from 129,040 respondents aged 15 years and older from 35 nationally representative surveys conducted between 2009 and 2018. Hypercholesterolemia care was quantified using cascade of care analyses in the pooled sample and by region, country income group, and country. Hypercholesterolemia was defined as (i) total cholesterol (TC) ≥240 mg/dL or self-reported lipid-lowering medication use and, alternatively, as (ii) low-density lipoprotein cholesterol (LDL-C) ≥160 mg/dL or self-reported lipid-lowering medication use. Stages of the care cascade for hypercholesterolemia were defined as follows: screened (prior to the survey), aware of diagnosis, treated (lifestyle advice and/or medication), and controlled (TC <200 mg/dL or LDL-C <130 mg/dL). We further estimated how age, sex, education, body mass index (BMI), current smoking, having diabetes, and having hypertension are associated with cascade progression using modified Poisson regression models with survey fixed effects. High TC prevalence was 7.1% (95% CI: 6.8% to 7.4%), and high LDL-C prevalence was 7.5% (95% CI: 7.1% to 7.9%). The cascade analysis showed that 43% (95% CI: 40% to 45%) of study participants with high TC and 47% (95% CI: 44% to 50%) with high LDL-C ever had their cholesterol measured prior to the survey. About 31% (95% CI: 29% to 33%) and 36% (95% CI: 33% to 38%) were aware of their diagnosis; 29% (95% CI: 28% to 31%) and 33% (95% CI: 31% to 36%) were treated; 7% (95% CI: 6% to 9%) and 19% (95% CI: 18% to 21%) were controlled. We found substantial heterogeneity in cascade performance across countries and higher performances in upper-middle-income countries and the Eastern Mediterranean, Europe, and Americas. Lipid screening was significantly associated with older age, female sex, higher education, higher BMI, comorbid diagnosis of diabetes, and comorbid diagnosis of hypertension. Awareness of diagnosis was significantly associated with older age, higher BMI, comorbid diagnosis of diabetes, and comorbid diagnosis of hypertension. Lastly, treatment of hypercholesterolemia was significantly associated with comorbid hypertension and diabetes, and control of lipid measures with comorbid diabetes. The main limitations of this study are a potential recall bias in self-reported information on received health services as well as diminished comparability due to varying survey years and varying lipid guideline application across country and clinical settings. CONCLUSIONS: Cascade performance was poor across all stages, indicating large unmet need for hypercholesterolemia care in this sample of LMICs-calling for greater policy and research attention toward this cardiovascular disease (CVD) risk factor and highlighting opportunities for improved prevention of CVD.

RESUMO

Online Mendelian Inheritance in Man (OMIM®), an online catalog of human genes and genetic disorders, has been used in the low- and middle-income countries largely as a tool for improving clinical care, teaching genetics and genomics, and for clinical and research analysis of next-generation sequencing. By facilitating free access to curated, updated, and comprehensive information in genetics and genomics, OMIM has led to better clinical care and research advancement in countries where clinicians and researchers in private or public hospitals and universities cannot afford to pay for other resources including journal subscriptions.

RESUMO

BACKGROUND: The coronavirus disease identified in 2019 (COVID-19) pandemic changed neurosurgery protocols to provide ongoing care for patients while ensuring the safety of health care workers. In Brazil, the rapid spread of the disease led to new challenges in the health system. Neurooncology practice was one of the most affected by the pandemic due to restricted elective procedures and new triage protocols. We aim to characterize the impact of the pandemic on neurosurgery in Brazil. METHODS: We analyzed 112 different types of neurosurgical procedures, with special detail in 11 neurooncology procedures, listed in the Brazilian Hospital Information System records in the DATASUS database between February and July 2019 and the same period in 2020. Linear regression and paired t-test analyses were performed and considered statistically significant at P < 0.05. RESULTS: There was an overall decrease of 21.5% (28,858 cases) in all neurosurgical procedures, impacting patients needing elective procedures (-42.46%) more than emergency surgery (-5.93%). Neurooncology procedures decreased by 14.89%. Nonetheless, the mortality rate during hospitalization increased by 21.26%. Linear regression analysis in hospitalizations (Slope = 0.9912 ± 0.07431; CI [95%] = 0.8231-1.159) and total cost (Slope = 1.03 ± 0.03501; CI [95%] = 0.9511-1.109) in the 11 different types of neurooncology procedures showed a P < 0.0001. The mean cost per type of procedure showed an 11.59% increase (P = 0.0172) between 2019 and 2020. CONCLUSIONS: The COVID-19 pandemic has increased mortality, decreased hospitalizations, and therefore decreased overall costs, despite increased costs per procedure for a variety of neurosurgical procedures. Our study serves as a stark example of the effect of the pandemic on neurosurgical care in settings of limited resources and access to care.

RESUMO

Hematopoietic cell transplantation (HCT) is the curative treatment for many malignant and non-malignant blood disorders and some solid cancers. However, transplant procedures are considered tertiary level care requiring a high degree of technicality and expertise and generating very high costs for hospital structures in developing countries as well as for patients without health insurance. During the 11th annual harmonization workshops of the francophone Society of bone marrow transplantation and cellular therapy (SFGM-TC), a designated working group reviewed the literature in order to elaborate unified guidelines, for developing the transplant activity in emerging countries. Access to infrastructure must comply with international standards and therefore requires a hospital system already in place, capable of accommodating and supporting the HCT activity. In addition, the commitment of the state and the establishment for the financing of the project seems essential.

RESUMO

Background As screening programs in low- and middle-income countries (LMICs) often do not have the resources to screen the entire population, there is frequently a need to target such efforts to easily identifiable priority groups. This study aimed to determine (1) how hypertension prevalence in LMICs varies by age, sex, body mass index, and smoking status, and (2) the ability of different combinations of these variables to accurately predict hypertension. Methods and Results We analyzed individual-level, nationally representative data from 1 170 629 participants in 56 LMICs, of whom 220 636 (18.8%) had hypertension. Hypertension was defined as systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or reporting to be taking blood pressure-lowering medication. The shape of the positive association of hypertension with age and body mass index varied across world regions. We used logistic regression and random forest models to compute the area under the receiver operating characteristic curve in each country for different combinations of age, body mass index, sex, and smoking status. The area under the receiver operating characteristic curve for the model with all 4 predictors ranged from 0.64 to 0.85 between countries, with a country-level mean of 0.76 across LMICs globally. The mean absolute increase in the area under the receiver operating characteristic curve from the model including only age to the model including all 4 predictors was 0.05. Conclusions Adding body mass index, sex, and smoking status to age led to only a minor increase in the ability to distinguish between adults with and without hypertension compared with using age alone. Hypertension screening programs in LMICs could use age as the primary variable to target their efforts.

RESUMO

BACKGROUND: Thyrotoxicosis is the state of thyroid hormone excess. But, in sub-Saharan Africa (SSA), specifically Northern Ethiopia, scientific evidence about thyrotoxicosis and its cardiac complications like dilated cardiomyopathy is limited. Therefore, this study aimed to explore the thyrotoxicosis presentation and management and identify factors associated with dilated cardiomyopathy in a tertiary hospital in Northern Ethiopia. METHODS: An institution-based cross-sectional study was conducted in Ayder Comprehensive Specialized Hospital from 2017 to 2018. Data from 200 thyrotoxicosis cases were collected using a structured questionnaire. After describing variables, logistic regression was conducted to identify independent predictors of dilated cardiomyopathy. Statistical significance was declared at p < 0.05. RESULTS: Mean age at presentation of thyrotoxicosis was 45 years and females accounted for 89 % of the cases. The most frequent etiology was multinodular toxic goiter (51.5 %). As well, the most common symptoms and signs were palpitation and goiter respectively. Thyroid storm occurred in 6 % of the cases. Out of 89 patients subjected to echocardiography, 35 (39.3 %) of them had dilated cardiomyopathy. And, the odds of dilated cardiomyopathy were higher in patients who had atrial fibrillation (AOR = 15.95, 95 % CI:5.89-38.16, p = 0.001) and tachycardia (AOR = 2.73, 95 % CI:1.04-7.15, p = 0.040). All patients took propylthiouracil and 13.0 % of them experienced its side effects. Concerning ß-blockers, propranolol was the most commonly (78.5 % of the cases) used drug followed by atenolol (15.0 %). Six patients underwent surgery. CONCLUSIONS: In developing countries like Ethiopia, patients with thyrotoxicosis have no access to methimazole which is the first-line anti-thyroid drug. Besides, they greatly suffer from dilated cardiomyopathy (due to late presentation) and side effects of propylthiouracil. Therefore, we recommend that patients should get adequate health information about thyrotoxicosis and anti-thyroid drugs including their side effects. Additionally, hospitals and other concerned bodies should also avail of TSH tests and methimazole at an affordable cost. Furthermore, community awareness about iodized salt and iodine-rich foods should be enhanced.

RESUMO

BACKGROUND: Surgical disease in Low Income Countries (LIC) is common, and overall provision of surgical care is poor. A key component of surgical health systems as part of universal health coverage (UHC) is financial risk protection (FRP) - the need to protect individuals from financial hardship due to accessing healthcare. We performed a systematic review to amalgamate current understanding of the economic impact of surgery on the individual and household. Our study was registered on Research registry (www.researchregistry.com). METHODS: We searched Pubmed and Medline for articles addressing economic aspects of surgical disease/care in low income countries. Data analysis was descriptive in light of a wide range of methodologies and reporting measures. Quality assessment and risk of bias analysis was performed using study design specific Joanna-Briggs Institute checklists. This study has been reported in line with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and AMSTAR (Assessing the methodological quality of systematic reviews) Guidelines. RESULTS: 31 full text papers were identified for inclusion; 22 descriptive cross-sectional studies, 4 qualitative studies and 5 economic analysis studies of varying quality. Direct medical, direct non-medical and indirect costs were variably reported but were substantial, resulting in catastrophic expenditure. Costs had far reaching economic impacts on individuals and households, who used entire savings, took out loans, reduced essential expenditure and removed children from school to meet costs. CONCLUSION: Seeking healthcare for surgical disease is economically devastating for individuals and households in LICs. Policies directed at strengthening surgical health systems must seek ways to reduce financial hardship on individuals and households from both direct and indirect costs and these should be monitored and measured using defined instruments from the patient perspective.

RESUMO

Cancer is one of the leading causes of death with 9.6 million deaths registered in 2018, of which 70% occur in Africa, Asia and Central and South America, the low-and middle-income countries (LMICs). The global annual expenditure on anticancer medicines increased from $96 billion in 2013 to $133 billion in 2017. This growth rate is several folds that of newly diagnosed cancer cases and therefore estimated to reach up to $200 billion by 2022. The Uganda Cancer Institute, Uganda's national referral cancer center, has increased access to cancer medicines through an efficient and cost-saving procurement system. The system has achieved cost savings of more than USD 2,000,000 on a total of 37 of 42 essential cancer medicines. This has resulted in 85.8% availability superseding the WHO's 80% target. All selected products were procured from manufacturers with stringent regulatory authority approval or a proven track record of quality products.

RESUMO

The global dairy sector is facing the challenge of reducing greenhouse gas (GHG) emissions whilst increasing productivity to feed a growing population. Despite the importance of this challenge, many developing countries do not have the required resources, specifically funding, expertise and facilities, for quantifying GHG emissions from dairy production and research. This paper aims to address this challenge by discussing the magnitude of the issue, potential mitigation approaches and benefits in quantifying GHG emissions in a developing country context. Further, the paper explores the opportunities for developing country dairy scientists to leverage resources from developed countries, such as using existing relevant GHG emission estimation models. It is clear that further research is required to support developing countries to quantify and understand GHG emissions from dairy production, as it brings significant benefits including helping to identify and implement appropriate mitigation strategies for local production systems, trading carbon credits and achieving the nationally determined contribution obligations of the Paris Agreement.

RESUMO

The diagnosis and treatment of patients with cancer requires access to imaging to ensure accurate management decisions and optimal outcomes. Our global assessment of imaging and nuclear medicine resources identified substantial shortages in equipment and workforce, particularly in low-income and middle-income countries (LMICs). A microsimulation model of 11 cancers showed that the scale-up of imaging would avert 3·2% (2·46 million) of all 76·0 million deaths caused by the modelled cancers worldwide between 2020 and 2030, saving 54·92 million life-years. A comprehensive scale-up of imaging, treatment, and care quality would avert 9·55 million (12·5%) of all cancer deaths caused by the modelled cancers worldwide, saving 232·30 million life-years. Scale-up of imaging would cost US$6·84 billion in 2020-30 but yield lifetime productivity gains of $1·23 trillion worldwide, a net return of $179·19 per $1 invested. Combining the scale-up of imaging, treatment, and quality of care would provide a net benefit of $2·66 trillion and a net return of $12·43 per $1 invested. With the use of a conservative approach regarding human capital, the scale-up of imaging alone would provide a net benefit of $209·46 billion and net return of $31·61 per $1 invested. With comprehensive scale-up, the worldwide net benefit using the human capital approach is $340·42 billion and the return per dollar invested is $2·46. These improved health and economic outcomes hold true across all geographical regions. We propose actions and investments that would enhance access to imaging equipment, workforce capacity, digital technology, radiopharmaceuticals, and research and training programmes in LMICs, to produce massive health and economic benefits and reduce the burden of cancer globally.
