RESUMO

Caregivers of autistic children in low-to-middle-income countries experience many barriers to access resources to support their child's development. Caregiver training is considered an evidence-based practice and may be a cost-effective way to support caregivers of autistic children in such settings. This study focuses on the cultural adaptation of Parents Taking Action (PTA; Magaña et al., Family Process, 56, 57-74, 2017) to support caregivers of autistic children in Paraguay. We conducted focus groups and individual interviews with 28 caregivers, autistic individuals, and professionals in Paraguay to understand caregivers' needs and to explore needed cultural adaptations of PTA to achieve contextual fit. Participants identified caregivers' need for accurate and reliable information, strategies to support children's growth, and emotional support and strategies to manage stress. Additionally, participants provided recommendations for adapting PTA considering the dimensions within the Cultural Adaptation Checklist (Lee et al., International Journal of Developmental Disabilities, 2023). This study is the first step in the iterative process of culturally adapting an intervention and the process described in this study may be appropriate for culturally adapting other interventions.

RESUMO

OBJECTIVES: To identify factors independently associated with respiratory syncytial virus (RSV) detection in infants admitted for viral bronchiolitis during 3 consecutive years, before and during the COVID-19 pandemic, in Bogota, Colombia, a middle-income country with a subtropical highland climate. METHODS: An analytical cross-sectional study was conducted before and during the COVID-19 pandemic, including patients with a diagnosis of viral bronchiolitis admitted to all the hospitals of the city between January 2019 and November 2021. We evaluated a set of a priori-selected predictor variables that included individual, healthcare system, meteorological, air pollutant, and COVID-19 variables. Since the variables analyzed are hierarchical in nature, multilevel modeling was used to identify factors independently associated with detection of RSV as the causative agent of viral bronchiolitis. RESULTS: A total of 13,177 patients were included in the study. After controlling for potential confounders, it was found that age (odds ratio [OR] 0.86; 95% confidence interval [CI] 0.76-0.97), a third level of medical care institution (OR 3.05; 95% CI 1.61-5.76), temperature (OR 1.60; 95% CI 1.24-2.07), rainfall (OR 1.003, 95% CI 1.001, 1.005), NO2 (OR 0.97; 95% CI 0.95-0.99), CO (OR 0.99; 95% CI 0.99-0.99), and COVID-19 pandemic period (OR 0.84, 95% CI 0.71-0.99) were independently associated with RSV detection in our sample of patients. CONCLUSIONS: The identified factors associated with RSV detection provide additional scientific evidence that may be useful in the development of specific interventions aimed at ameliorating or preventing the impact of RSV in Bogota and probably other similar low- to middle-income countries in high-risk infants.

RESUMO

OBJECTIVE: To evaluate the effectiveness of the implementation of intervention packages for postpartum hemorrhage (PPH) management in pregnant women hospitalized in a High Obstetric Complexity Unit in a Latin American country. METHODS: Retrospective cohort study including pregnant women with PPH attended between January 2011 to December 2019. Three periods of time were defined according to management strategies We performed univariate and multivariate robust Poisson regression logistic models for each of the outcomes derived from each period. RESULTS: We included 602 patients. There was a reduction in period 3 of the incidence of massive PPH (16% versus 12% P < 0.001, relative risk [RR] 0.61, 95% confidence interval [CI] 0.44-0.85; P = 0.003), major surgery (24%, 13%, 11%, P = 0.002, RR 0.54, 95% CI 0.33-0.883; P = 0.014), and admission to the intensive care unit (ICU) (14%, 7%, 6.1%, P = 0.0, RR 0.40, 95% CI 0.17-0.96 P = 0.00). CONCLUSION: The implementation of PPH intervention packages in a hospital in a middle-income country from Latin America, led to a significant decrease in the incidence of massive bleeding, the rate of major surgery, and the ICU stay of pregnant women affected by this condition.

RESUMO

OBJECTIVE: The use of emergency department (ED)-initiated outpatient oxygen therapy has been considered to be a possible alternative to hospitalization for otherwise healthy-appearing, well-hydrated infants with uncomplicated disease. However, a formal economic evaluation of this treatment strategy is lacking. The aim of the present study was to compare the cost-effectiveness of ED-initiated outpatient oxygen therapy versus conventional inpatient hospitalization in infants with uncomplicated hypoxic bronchiolitis living in Bogota, the high-altitude capital city of Colombia, a middle-income country (MIC). METHODS: A decision analysis model was developed to estimate the cost-effectiveness of ED-initiated outpatient oxygen therapy versus hospitalization. The main outcome of the model was avoidance of admission to a high-dependency unit. RESULTS: Compared to hospitalization, ED-initiated outpatient oxygen therapy was associated with lower total costs (US$306.7 vs. US$638.7 average cost per patient) and a higher probability of avoidance of admission to a high-dependency unit (0.9528 vs. 0.8960), thus leading to dominance. The results were robust to deterministic and probabilistic sensitivity analyses. CONCLUSIONS: Our study suggests that in infants attending the ED with an uncomplicated hypoxic bronchiolitis episode in the city of Bogota, a high-altitude city, ED-initiated outpatient oxygen therapy is a dominant strategy compared to conventional inpatient hospitalization, because it involves a higher probability of avoidance of admission to a high-dependency unit, at lower total treatment costs.

RESUMO

OBJECTIVES: The aim of the present study is to gain insight into the identification of region-specific factors associated with poor outcomes in children under 5 years of age with confirmed respiratory syncytial virus acute lower respiratory infection (RSV-ALRI) living in Colombia, a middle-income country, based on the National Public Health Surveillance System of the country. METHODS: An analytical cross-sectional study was conducted using epidemiological data from the records of morbidity and mortality of respiratory infections as registered in the surveillance system report of the National Institute of Health of Colombia 2018, including children under 5 years of age with confirmed RSV-ALRI. Predictor variables included demographic and clinical variables, as well as variables measured after hospital attendance. Outcome variables analyzed were respiratory failure, the need for pediatric intensive care unit admission, and mortality. RESULTS: Of a total of 8470 patients with a diagnosis of ALRI, we selected 1215 (14.3%) that were under 5 years of age and were positive for RSV. After controlling for potential confounders, it was found that age, gender, socioeconomic stratum, incomplete pneumococcal conjugate vaccine 13 immunization for age, cardiac disease, and malnutrition as comorbidities, chest X-ray findings, and development of sepsis independently predicted poor outcomes among the patients analyzed. CONCLUSIONS: The identified predictors for poor outcomes in RSV-affected children may be helpful for guiding efficient and targeted national and/or regional programs and public policies to assist in achieving Goal 3 of the Sustainable Development Goals adopted by the United Nations in 2015.

RESUMO

BACKGROUND: Although the use of biomarkers to assess health outcomes has recently gained momentum, literature is still scarce for low- to middle-income countries. This paper explores the relationship between primary care coverage and individual health in Brazil using a dataset of blood-based biomarkers collected by the Brazilian National Health Survey. Both survey data and laboratory results were crossed with coverage data from the Family Health Strategy (ESF) program, the most important primary care program in Brazil; the coverage measures aim to capture both direct (household) and indirect (spill-over) effects. METHODS: The empirical strategy used a probit model to estimate the relationship between ESF program coverage and the likelihood of abnormal biomarker levels while controlling for a rich set of individual and household characteristics based on data from the national survey. RESULTS: Household ESF coverage was associated with a lower likelihood of abnormal results for biomarkers related to anemia (marginal effect between - 2.16 and - 2.18 percentage points), kidney failure (between - 1.01 and - 1.19 p.p.), and arterial hypertension (between - 1.48 and - 1.64 p.p). The likelihood of abnormal levels of white blood cells and thrombocytes was negatively related to primary care coverage (marginal effect between - 1.8 and - 2 p.p.). The spillover effects were relevant for kidney failure and arterial hypertension, depending on the regional level. Although not sensitive to household coverage, diabetes mellitus was negatively associated with the state supply of primary care, and abnormal cholesterol levels did not present any relationship with ESF program coverage. CONCLUSIONS: The presence of spillover effects of ESF program coverage regarding these conditions reveals that the strengthening of primary care by increasing the household registration and the regional density of ESF teams is an efficient strategy to address important comorbidities.

RESUMO

BACKGROUND: A common approach for measuring place-based exposure is to use geographically-defined administrative boundaries and to link neighborhood characteristics at this level. This approach, however, may not be feasible in low-to middle-income countries where neighborhood-level data are limited or unavailable, and administrative boundaries are often unstandardized and not proportional to population size. Furthermore, such traditional approaches may not be appropriate for marginalized populations whose environments can be more difficult to study. In this paper, we describe two innovative and feasible methods to generate geospatial data to characterize and assess the role of risk environments on drug use among female sex workers living with HIV in the Dominican Republic. METHODS: Participatory geographic mapping and daily activity space travel diaries were employed. RESULTS: The methods presented in this study were feasible to implement, acceptable by study participants, and yielded rich geospatial data to analyze the impact of contextual factors on risk behaviors of female sex workers in a low-to middle-income country. CONCLUSION: Participatory geographic mapping and activity space diaries are two alternative methods for collecting geospatial data among hard-to-reach populations in resource constrained settings. Moreover, the methods are interactive and educational, allowing study participants to take an active role in the data collection process and potentially allowing for a deeper understanding of place-based effects on health and behavior.

RESUMO

PURPOSE OF REVIEW: Acute leukemias represent a tremendous threat to public health around the globe and the main cause of death due to disease in scholar age children from developing nations. Here, we review their current status in Mexico, as a paradigm of study, and the major challenges to control systemic diseases like childhood cancer. RECENT FINDINGS: A unique molecular epidemiology, late/low precision diagnosis, limited access to treatment, toxicity associated with therapy, continuous exposure to environmental risk factors, and the high frequency of early relapses are some of the factors cooperating to low rates of survival in low-to-medium-income countries. Deliberative dialogues and exhaustive programs have emerged as promising means of advancing evidence-informed policy, by providing a structured forum for key stakeholders to integrate scientific and pragmatic knowledge about complex health concerns. A system-wide strategy based on the comprehensive leukemia identity is essential for a meaningful decline in early childhood mortality.

RESUMO

BACKGROUND: Pediatric cancer cure rates differ among high-income countries (HIC) and upper middle-income countries (UMIC). We have compared individual capacities of two major referral pediatric centers from a HIC and an UMIC caring for children with central nervous system (CNS) cancer. METHODS: A quantitative needs assessment questionnaire and key informant interviews, distributed in March of 2017, were used to evaluate the treatment of children with CNS cancer at Grupo de Apoio ao Adolescente e à Criança com Câncer (GRAACC) children's cancer center in São Paulo, Brazil and Nationwide Children's Hospital (NCH) in Columbus, Ohio, United States of America (USA). RESULTS: Both hospitals had 24-hour pediatric oncology, nursing and intensivist coverage. Supportive care available at both institutions included social workers, psychologists, child life specialists, and physical/occupational/speech therapists. Differences included two part-time neuroradiologists and one pathologist specializing in neuropathology at IOP/GRAACC/UNIFESP, whereas eight full-time neuroradiologists and two neuropathologists at NCH/OSU. There were four pediatric neurosurgeons on staff at each hospital; however, there were only 2 operative days per week at IOP/GRAACC/UNIFESP, compared with 7 days at NCH/OSU. Additionally, time to initiation of radiation therapy at IOP/GRAACC/UNIFESP extended 2-4 weeks compared with less than 1 week at NCH/OSU. CONCLUSIONS: Center-specific differences in resources exist in highly specialized hospitals caring for children with CNS cancer in HIC and UMIC. This quantitative needs assessment may facilitate the development of targeted strategies for effective interventions to improve on the management of children with CNS cancers.

RESUMO

Rapid urbanization in low- and middle-income countries (LMIC) is associated with increasing population living in informal settlements. Inadequate infrastructure and disenfranchisement in settlements can create environments hazardous to health. Placed-based physical environment upgrading interventions have potential to improve environmental and economic conditions linked to health outcomes. Summarizing and assessing evidence of the impact of prior interventions is critical to motivating and selecting the most effective upgrading strategies moving forward. Scientific and grey literature were systematically reviewed to identify evaluations of physical environment slum upgrading interventions in LMICs published between 2012 and 2018. Thirteen evaluations that fulfilled inclusion criteria were reviewed. Quality of evaluations was assessed using an adapted Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Findings were then pooled with those published prior to 2012. Narrative analysis was performed. Of thirteen evaluations, eight used a longitudinal study design ("primary evaluations"). All primary evaluations were based in Latin America and included two housing, two transportation, and four comprehensive intervention evaluations. Three supporting evaluations assessed housing interventions in Argentina and South Africa; two assessed a comprehensive intervention in India. Effects by intervention-type included improvements in quality of life and communicable diseases after housing interventions, possible improvements in safety after transportation and comprehensive interventions, and possible non-statistically significant effects on social capital after comprehensive interventions. Effects due to interventions may vary by regional context and intervention scope. Limited strong evidence and the diffuse nature of comprehensive interventions suggests a need for attention to measurement of intervention exposure and analytic approaches to account for confounding and selection bias in evaluation. In addition to health improvements, evaluators should consider unintended health consequences and environmental impact. Understanding and isolating the effects of place-based interventions can inform necessary policy decisions to address inadequate living conditions as rapid urban growth continues across the globe.

RESUMO

BACKGROUND: Social engagement forms the basis of social relationships by providing a sense of belonging, social identity, and fulfillment. Previous research demonstrates that social engagement was associated with positive health behaviors among older adults. However, the results have been different across health-related behaviors, and mostly based on data from high-income countries. For example, studies from the US and UK showed that social engagement was protective against smoking, while others found social engagement encouraged more smoking in many Asian cultures. In this study, we aim to examine the association between social engagement and a range of health-related behaviors and subjective well-being among older adults in six low- to middle-income countries. METHODS: Data from the WHO Study on Global Ageing and Adult Health (SAGE Wave 1) were used. A total of 33,338 individuals aged 50 and older in China, Russia, India, Ghana, South Africa, and Mexico were included. Social engagement, tobacco use, alcohol consumption, fruit and vegetable intake, physical activity, sedentary behavior, sleep duration, depression symptoms, self-rated health status, and quality of life were assessed using established self-reported measures. Multiple logistic regression models were used to examine the relationship between social engagement and nine outcome variables, adjusting for socio-demographic characteristics. RESULTS: Lower levels of social engagement were positively related to physical inactivity, prolonged sitting time, unhealthy sleep duration, perceived depression, poor self-rated health, and low quality of life. However, the associations between social engagement and tobacco use, excessive drinking, and insufficient fruit and vegetable intake were mixed across countries. CONCLUSION: This international study found high social engagement as a potential health-promoting factor in some low- to middle-income countries. Although the impacts of social engagement on tobacco and alcohol use and diet were complicated and culture-specific, interventions at both individual and community levels should encourage healthy lifestyles through positive social engagement.

RESUMO

Aim: The study was conducted to understand how key determinants of the Patient Financial Eligibility Tool (PFET), a previously validated tool for assessing patients' ability to contribute to their medication costs, vary across countries. Materials & methods: A clustering analysis was conducted on economic data from 1404 patients from Thailand (n = 947), the UAE (n = 347) and Mexico (n = 110). Results: The analysis identified seven patient clusters, including globally wealthy or poor patients (14%/48%) and those with only selectively increased PFET economic indicators (38%), and revealed country-specific differences in the correlation between PFET metrics and patients' overall economic status. Conclusion: The PFET is a versatile tool that can be adapted to each country's economic context to assess patients' ability to contribute to their medication costs.

RESUMO

BACKGROUND: The need for neurosurgical care across the globe remains a public health issue. The creation of sustainable neurological surgery departments and training programs will be indispensable in alleviating the burden of neurological disease in low to middle income countries (LMICs). METHODS: We reviewed the history of the neurological surgery department and residency program of Santarém in the state of Pará, Brazil, from 1999 to the present. We have described the epidemiology unique to the region and provided evidence of a sustainable practice in a LMIC. The challenges, limitations, and resources were explored. RESULTS: We have provided a historical vignette of the evolution of neurological surgery in the Brazilian Amazon, including the creation of a sustainable neurological surgery practice and accredited residency program. In addition, we assessed the neurological surgery burden and epidemiology unique to the region, with an emphasis on the community and indigenous health in this remote area. We also explored the future directions of this example, which could affect the international neurological surgery community. CONCLUSION: A sustainable neurosurgery practice and training program is possible in a LMIC. Training neurosurgeons in developing regions of LMICs is a sustainable method to decrease the morbidity and mortality of neurological diseases and prevent the misdistribution of physicians in a country. We encourage adaptation of sustainable neurological surgery practices in similar regions across the world to increase access to necessary neurosurgical care.

RESUMO

INTRODUCTION: The outcomes for adolescents and young adults (AYAs) with acute myeloid leukemia (AML) have been poorly characterized in Hispanics in low- to middle-income countries. The results are influenced by biologic and socioeconomic factors. The clinical paths for AYA patients with AML are reported. PATIENTS AND METHODS: A retrospective analysis of AYA and pediatric AML patients aged 1 to 39 years during 2003 to 2016 from a single reference center in Northeast Mexico treated with a 7+3 standard protocol was performed. The 5-year overall survival (OS) and event-free survival (EFS) were estimated using Kaplan-Meier analysis. The hazard ratios for relapse and death were estimated using a Cox regression model. The patients with promyelocytic leukemia were analyzed separately. RESULTS: The study included 110 non-PML AML patients, 39 children and 71 AYAs. No difference in complete remission was found (P = .446), although the overall response rate was greater in the children (87.2% vs. 69% in AYAs; P = .034). The 5-year EFS rate was 33% for the children versus 9.3% in the AYAs at a median follow-up of 22 and 9 months, respectively (P = .008). The 5-year OS rate was 51% in the children and 22% in the AYAs (P = .001). Of the 44 AYAs with complete remission, 29 (65%) developed a relapse. Of the 39 children and 71 AYAs, 20 children (51.3%) and 21 AYAs (29.6%) underwent transplantation (P = .024). Patients with refractory disease had a 1-year OS rate of 14.4%. Older age (hazard ratio [HR], 2.55; P = .002) and white blood cell count > 50 × 109/L (HR, 1.79; P = .023) were significant for death, and transplantation was protective (HR, 0.57; P = .023). CONCLUSION: Low EFS and OS rates were found for AML patients in the AYA group. To improve survival rates, intensified chemotherapy regimens and early hematopoietic stem cell transplantation are needed.

RESUMO

AIM: This study estimated the causes of neonatal death using an algorithm for low-resource areas, where 98% of the world's neonatal deaths occur. METHODS: We enrolled women in India, Pakistan, Guatemala, the Democratic Republic of Congo, Kenya and Zambia from 2014 to 2016 and tracked their delivery and newborn outcomes for up to 28 days. Antenatal care and delivery symptoms were collected using a structured questionnaire, clinical observation and/or a physical examination. The Global Network Cause of Death algorithm was used to assign the cause of neonatal death, analysed by country and day of death. RESULTS: One-third (33.1%) of the 3068 neonatal deaths were due to suspected infection, 30.8% to prematurity, 21.2% to asphyxia, 9.5% to congenital anomalies and 5.4% did not have a cause of death assigned. Prematurity and asphyxia-related deaths were more common on the first day of life (46.7% and 52.9%, respectively), while most deaths due to infection occurred after the first day of life (86.9%). The distribution of causes was similar to global data reported by other major studies. CONCLUSION: The Global Network algorithm provided a reliable cause of neonatal death in low-resource settings and can be used to inform public health strategies to reduce mortality.

RESUMO

BACKGROUND: Itapúa is a rural department in Paraguay with a population of about 500,000 and a high degree of agro-mechanization for the production of soybean and other crops. So far, only basic health care is provided. Here we analyzed the cancer mortality in this region as a first step towards epidemiological data for cancer prevention. METHODS: We calculated the age-adjusted mortality rates according to world standard (AMRWs) for the major cancer sites in both males and females between 2003 and 2012, and estimated the differences between the capital and more central districts of Itapúa vs. remote districts. RESULTS: There were about 2000 cancer deaths in the decade studied, with AMRWs for all malignancies of 90.9/100,000 in males from central vs. 49.1/100,000 in remote districts and 69.0/100,000 vs. 45.0/100,000 in women. Cancer was mentioned in 12.4% of all death certificates and outweighed mortality from certain infectious and parasitic diseases (3.6%). Cause of death was ill-defined in 19.6% of all death certificates, especially in remote regions and among the elderly. The part of cancer located in the uterus (47.8%) or cell type of neoplasm of the lymphatic or hematopoietic system (73.1%) were often not specified. The uterus (mainly the cervix) (C53-C55) was the leading cancer site in women with AMRWs of 17.2/100,000 in central and 14.0/100,000 in remote districts, followed by the breast. Lung and prostate were the leading cancer sites among men. The lung cancer mortality rate was 19.3/100,000 in the central region but 9.5/100,000 in remote districts. Although children comprised 36% of the population, only 24 death certificates listed cancer as cause of death in this decade. CONCLUSIONS: Analysis of cancer mortality in this rural region of Paraguay, which lacks resources for diagnostics and care, revealed an already large number of cases, with higher rates in the central region than in remote districts. Lung and uterus (primarily the cervix) are common cancer sites and indicate the potential for prevention. However, the quality of the vital statistics needs to be improved. The true cancer burden is most likely underestimated, especially in remote regions and children.

RESUMO

BACKGROUND: Surgical burden is a large and neglected global health problem in low- and middle-income countries. With the increasing trauma burden, the goal of this study was to evaluate the trauma capacity of hospitals in the central plateau of Haiti. MATERIALS AND METHODS: The World Health Organization Emergency and Essential Surgical Care survey was adapted with a focus on trauma capacity. Interviewers along with translators administered the survey to key hospital staff. RESULTS: Seven hospitals in the region were surveyed. Of the hospitals surveyed, 3/7 had functioning surgical facilities. None of the hospitals had trauma registries. 71% of the hospitals had no formal trauma guidelines. 2/7 hospitals had a general surgeon available 100% of the time. All surgical facilities had oxygen cylinders available 100% of the time, but three of the primary level hospitals only had it available 51%-90% of the time. Intubation equipment was available at 57% of the facilities. Ventilators were only available in the operating room. Only the largest hospital had a computed tomography scanner. Other hospitals (66%) had a functioning x-ray machine 76%-90% of the time. Hospitals (57%) had an ultrasound machine. The most common reasons for referral were lack of appropriate facilities and supplies at the primary level care centers or lack of trained personnel at higher-level facilities. CONCLUSIONS: Trauma capacity in the central plateau of Haiti is limited. There is a great need for more personnel, trauma training at all staff levels, emergency care guidelines, trauma registries, and imaging equipment and training, specifically in ultrasonography. To accomplish this, coordination is needed between the Haitian government and local and international nongovernmental organizations.
