RESUMO

OBJECTIVE: The aim of the present study was to identify the risk factors for severe maternal outcomes (SMO) of women with suspected or confirmed infections using the data from the WHO global maternal sepsis study (GLOSS). METHODS: We conducted a secondary analysis of the GLOSS cohort study, which involved pregnant or recently pregnant women with suspected or confirmed infection around 713 health facilities in 52 low- and middle-income countries, and high-income countries. A nested case-control study was conducted within the GLOSS cohort. Cases included infection-related maternal deaths or near misses, while controls represented non-SMO. Logistic mixed models, adjusting for country variations, were employed. Using univariate analysis, we calculated crude odds ratios (crude OR) and their 95% confidence interval (95% CI). Variables were identified with less than 16% missing data, and P values less than 0.20 were used to perform the multivariate logistic model multilevel. RESULTS: A total of 2558 women were included in the analysis. As for the cases, 134 patients were found in the pregnant in labor or not in labor group and 246 patients in the postpartum or postabortion group. Pregnant women with prior childbirths faced a 64% increased risk of SMO. Ante- or intrapartum hemorrhage increased risk by 4.45 times, while trauma during pregnancy increased it by 4.81 times. Pre-existing medical conditions elevated risk five-fold, while hospital-acquired infections increased it by 53%. Secondary infections raised risk six-fold. Postpartum/postabortion women with prior childbirths had a 45% elevated risk, and pre-existing medical conditions raised it by 2.84 times. Hospital-acquired infections increased risk by 93%. Postpartum hemorrhage increased risk approximately five-fold, while abortion-related bleeding doubled it. Previous cesarean, abortion, and stillbirth also elevated risk. CONCLUSIONS: Key risk factors for SMO include prior childbirths, hemorrhage, trauma, pre-existing conditions, and hospital-acquired or secondary infections. Implementing effective alert systems and targeted interventions is essential to mitigate these risks and improve maternal health outcomes, especially in resource-limited settings.

RESUMO

INTRODUCTION: Outcomes from diabetic foot infections (DFIs) at the major referral hospital (Hospital Nacional de San Benito) in El Petén, Guatemala have not been analyzed. We hypothesized that poor diabetic control might be associated with a high rate of major lower extremity amputations (mLEAs; above the ankle). METHODS: We performed a retrospective analysis at Hospital Nacional de San Benito between (8/14 and 6/23) in patients presenting with DFIs. Patients receiving mLEAs were compared with all others (AO = [trans-metatarsal amputations, toe amputations, incision and drainage, and antibiotic treatment]). Interviews surgeons were undertaken to ascertain reasons for index operation choice. Univariable and multivariable analyses were undertaken to determine factors associated with mLEAs. RESULTS: Of 110 patients with DFIs, there were 23 mLEAs (above the knee = 21, below the knee = 2). Age, duration with diabetes, and a prior ipsilateral minor amputation were associated with mLEAs. Multivariable analysis identified white blood cell count as significant for mLEA (odds ratio = 1.5 95% confidence interval [1.0 to 2.5]). Cited reasons for a high rate of above the knee amputation (AKAs) versus below the knee amputation were patient related (advanced disease, patient frailty, and poor compliance), systemic (lack of vascular equipment and knee immobilizer), and surgeon related. CONCLUSIONS: This cohort of patients presented with an average of 15 years with diabetes mellitus and poor adherence to diabetic treatment (40%). Many of these diabetic patients developed a DFI requiring mLEAs (21%), most of which were AKAs (91%). Efforts to minimize the number of AKA versus below the knee amputation require immediate attention. Programs to adhere to DM control and foot care in patients with DM are urgently needed.

RESUMO

Convalescent plasma has increasingly been used to treat various viral infections and confer post-exposure prophylactic protection during the last decade and has demonstrated favorable clinical outcomes in patients infected with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) during the recent COVID-19 pandemic. The pandemic has highlighted the need for cost-effective, accessible, and easy-to-use alternatives to conventional blood plasmapheresis techniques, allowing hospitals to become more self-sufficient in harvesting and transfusing donor plasma into recipients in a single setting. To this end, the use of a membrane-based bedside plasmapheresis device (HemoClear) was evaluated in an open-label, non-randomized prospective trial in Suriname in 2021, demonstrating its practicality and efficacy in a low-to middle-income country. This paper will review the use of this method and its potential to expedite the process of obtaining convalescent plasma, especially during pandemics and in resource-constrained settings.

RESUMO

The risk that COVID-19 poses for mortality risk in individuals with schizophrenia in low- and middle-income countries has only been the subject of a few studies. In this retrospective study, we examined the standardized mortality ratio (SMR), by age group and sex, in a cohort of patients diagnosed with schizophrenia (n = 20,417), with second-generation antipsychotics, in a South Brazilian State database (Paraná-Brazil). We performed a linkage with the Brazilian Mortality Information System database between 2020 and 2021. We also assessed in a logistic regression how clozapine could affect COVID-19 mortality controlling by sex, age, and presence of obesity. A secondary analysis was to compare mortality with SMR due to COVID-19 in individuals with and without obesity. Compared to the State population (8,850,682 individuals), those with schizophrenia had more than two times greater risk of dying from COVID-19 (SMR = 2.21, 95 % CI: 1.90-2.55). Between the ages of 16 and 29, their risk is more than ten times higher than the state population (SMR = 10.18, 95 % CI: 4.73-19.33). Obesity showed an almost twofold risk of dying from COVID-19 in the patient's group (OR = 1.89, 95 % CI: 1.39-2.57). Clozapine was not found as a protector or a risk factor for COVID-19 mortality. In Brazil, a middle-income nation, people with schizophrenia are more likely to die prematurely from COVID-19. The burden of schizophrenia is higher in younger and in patients with obesity.

RESUMO

Tobacco use is associated with serious health problems. Global efforts, such as the World Health Organization's Framework for Tobacco Control, have reduced tobacco use, but challenges remain. Initially perceived as aids for smoking cessation, e-cigarettes have gained popularity among young people and non-smokers. Government approaches to regulating e-cigarettes range from treating them like tobacco, requiring a prescription for their use to outright bans. Although touted as a valuable alternative, evidence suggests that increased e-cigarette use carries potential direct and indirect health risks, necessitating urgent regulatory measures on a global scale. Lack of defined and uniform regulations poses substantial public health risks, compounded by marketing targeting vulnerable groups. Immediate interventions, public awareness, and research are essential to effectively control the current e-cigarette epidemic.

RESUMO

BACKGROUND: Guillain-Barré Syndrome (GBS) can lead to significant functional impairments, yet little is understood about the recovery phase and long-term consequences for patients in low- and medium-income countries. OBJECTIVE: To evaluate the functional status and identify factors influencing outcomes among patients with GBS in Colombia. METHODS: Telephone interviews were conducted with GBS patients enrolled in the Neuroviruses Emerging in the Americas Study between 2016 and 2020. The investigation encompassed access to health services and functional status assessments, utilizing the modified Rankin Scale (mRS), GBS Disability Score (GDS), Barthel Index (BI), and International Classification of Functioning (ICF). Univariate analysis, principal component analysis, linear discriminant analysis, and linear regression were employed to explore factors influencing functional status. RESULTS: Forty-five patients (mean age = 50[±22] years) with a median time from diagnosis of 28 months (IQR = 9-34) were included. Notably, 22% and 16% of patients did not receive rehabilitation services during the acute episode and post-discharge, respectively. Most patients demonstrated independence in basic daily activities (median BI = 100, IQR = 77.5-100), improvement in disability as the median mRS at follow-up was lower than at onset (1 [IQR = 0-3] vs. 4.5 [IQR = 4-5], p < 0.001), and most were able to walk without assistance (median GDS = 2, IQR = 0-2). A shorter period from disease onset to interview was associated with worse mRS (p = 0.015) and ICF (p = 0.019). Negative outcomes on GDS and ICF were linked to low socioeconomic status, ICF to the severity of weakness at onset, and BI to an older age. CONCLUSIONS: This study underscores that the functional recovery of GBS patients in Colombia is influenced not only by the natural course of the disease but also by socioeconomic factors, emphasizing the crucial role of social determinants of health.

RESUMO

BACKGROUND: The death of a child is one of the most devastating events a family can face, resulting in significant physical and psychosocial morbidity. Bereavement support programs have been developed in high-income contexts to address this need. However, little is known about implementing bereavement programs in low-and middle-income countries (LMICs). Here, we describe the implementation of a bereavement program for parents whose children died due to cancer or other catastrophic illnesses. METHODS: We conducted a retrospective analysis to describe the implementation of a hospital-based End of Life (EoL) care and bereavement program. This program was developed in several stages, including an assessment of bereaved families, development program guidelines, staff training, piloting of the program, refinement, and standardization. The program was developed between 2019 and 2021 in a nonprofit, teaching hospital and referral center for southwestern Colombia. RESULTS: Several tools were developed as key components of the bereavement program: a virtual bereavement course; guidance for EoL and bereavement communication and care, memory making, and follow-up calls; a condolence letter template, and group support workshops. A total of 956 healthcare professionals were trained, 258 follow-up calls to bereaved parents were made, 150 individual psychological follow-ups to parents with complicated grief occurred, 79 condolence letters were sent, and 10 support group workshops were carried out. Challenges were identified and overcome, such as limited resources and staff, and cultural perceptions of death. In 2021, this program received an award by the hospital as the Best Strategy to Humanize Healthcare. CONCLUSIONS: This study highlights the feasibility of developing and implementing EoL and bereavement care programs for parents and families within hospitals in LMICs. Lack of resources, staff, and training are some of the identified challenges to implementation. Utilizing methodological tools allows us to identify facilitator factors and deliverable outcomes of our EoL and bereavement program. This model provides a valuable framework for resource-limited settings.

RESUMO

Purpose of Review: Despite the availability of effective vaccines against the three primary pathogens (Streptococcus pneumoniae, Haemophilus influenzae type b, and Neisseria meningitidis) that cause bacterial meningitis, this condition remains a significant cause of morbidity, neurologic sequelae, and mortality among children and adults living in low-income and middle-income countries. Recent Findings: Bacterial meningitis represents a significant public health challenge for national and global health systems. Since vaccine-preventable meningitis remains highly prevalent in low-income and middle-income countries, the World Health Organization (WHO) recently developed a global roadmap to defeating meningitis by 2030 and ameliorating its associated neurological sequelae. Summary: There is a need for a global approach to surveillance and prevention of bacterial meningitis. Increasing vaccination coverage with conjugate vaccines against pneumococcus and meningococcus with optimal immunization schedules are high-value healthcare interventions. Additionally, overcoming diagnostic challenges and the early institution of empirical antibiotic therapy and, when feasible, adjunctive steroid therapy constitutes the pillars of reducing the disease burden of bacterial meningitis in resource-limited settings.

RESUMO

INTRODUCTION: Schizophrenia is a debilitating disorder that affects a significant proportion of the population and leads to impaired functionality and long-term challenges. The first episode of psychosis (FEP) is a critical intervention stage for improving long-term outcomes. The GAPi program was established in São Paulo, Brazil to provide early intervention services and evaluate biomarkers in individuals with FEP. This article delineates the objectives of the GAPi program, detailing its innovative research protocol, examining the clinical outcomes achieved, and discussing the operational challenges encountered during its initial decade of operation. METHODS: The study comprised a prospective cohort of antipsychotic-naïve individuals with first-episode psychosis aged between 16 and 35 years. Participants were recruited from a public psychiatric facility in São Paulo. Emphasizing the initiative's commitment to early intervention, clinical assessments were systematically conducted at baseline and at two months, one year, two years, and five years of treatment to capture both short- and medium-term outcomes. Various assessment tools were utilized, including structured interviews, symptom scales, the Addiction Severity Index, and functional assessments. RESULTS: A total of 232 patients were enrolled in the cohort. Among them, 65.95 % completed the 2-month follow-up. Most patients presented with schizophrenia spectrum disorders, followed by bipolar disorder and major depressive disorder with psychotic features. Treatment response rates and remission rates were evaluated at different time points, with promising outcomes observed. The program also assessed socio-demographic factors, substance use, family history, and genetic and biomarker profiles, providing valuable data for research. DISCUSSION: The GAPi program has emerged as the largest ongoing cohort of antipsychotic-naïve first-episode psychosis in Latin America, contributing to the understanding of early psychosis in low- and middle-income countries. Despite operational challenges, the program has demonstrated efficacy in reducing the duration of untreated psychosis and in improving clinical outcomes. A multidisciplinary approach, including pharmacological treatment, psychosocial interventions, and family involvement, has been instrumental in enhancing treatment adherence and long-term prognosis. CONCLUSION: The GAPi program represents a valuable model for early intervention in first-episode psychosis and provides insights into the pathophysiology, treatment, and long-term outcomes of individuals with schizophrenia and related disorders. Continued research and resource allocation are essential for addressing operational challenges and expanding early intervention services in low- and middle-income countries.

RESUMO

BACKGROUND: Tuberculosis is a leading cause of death worldwide, and food insecurity is known to negatively influence health outcomes through multiple pathways. Few studies have interrogated the relationship between food insecurity and tuberculosis outcomes, particularly independent of nutrition. METHODS: We conducted a prospective cohort study of adults initiating first-line treatment for clinically suspected or microbiologically confirmed drug-sensitive tuberculosis at a rural referral center in Haiti. We administered a baseline questionnaire, collected clinical data, and analyzed laboratory samples. We used logistic regression models to estimate the relationship between household food insecurity (Household Hunger Scale) and treatment failure or death. We accounted for exclusion of patients lost to follow-up using inverse probability of censoring weighting and adjusted for measured confounders and nutritional status using inverse probability of treatment weighting. RESULTS: We enrolled 257 participants (37% female) between May 2020 and March 2023 with a median age (interquartile range) of 35 (25-45) years. Of these, 105 (41%) had no hunger in the household, 104 (40%) had moderate hunger in the household, and 48 (19%) had severe hunger in the household. Eleven participants (4%) died, and 6 (3%) had treatment failure. After adjustment, food insecurity was significantly associated with subsequent treatment failure or death (odds ratio 5.78 [95% confidence interval, 1.20-27.8]; P = .03). CONCLUSIONS: Household food insecurity at tuberculosis treatment initiation was significantly associated with death or treatment failure after accounting for loss to follow-up, measured confounders, and nutritional status. In addition to the known importance of undernutrition, our findings indicate that food insecurity independently affects tuberculosis treatment outcomes in Haiti.

RESUMO

Birth cohort studies across the world have yielded information that has been used to inform policy and programme decisions that have improved the health and well-being of populations. A few such studies have been conducted in low- and middle-income countries due to funding, methodological and other challenges. This paper briefly reviews the methods of comprehensive birth cohort studies with extensive follow-up of participants through the life course conducted in low- and middle-income countries. It then reviews the first Jamaican birth cohort study of 1986 and discusses the methodological advances in implementing JA KIDS, the second Jamaican birth cohort study conducted in 2011. The aims and methods of JA KIDS are described in detail.

RESUMO

BACKGROUND: Cognitive stimulation therapy (CST) is an evidence-based, group psychosocial intervention for people with dementia, and it has a positive impact on cognition and quality of life. CST has been culturally adapted for use globally. It was developed as a face-to-face intervention but has recently been adapted for online delivery. OBJECTIVE: In this study, we aimed to explore the feasibility and acceptability of online or virtual CST (vCST) delivery in India and Brazil, emphasizing barriers and facilitators to implementation. METHODS: A single-group, multisite, mixed methods, feasibility study was conducted, with nested qualitative interviews. Primary feasibility outcomes were recruitment rate, attendance, attrition, acceptability, and outcome measure completion. Exploratory pre- and postintervention measures, including cognition and quality of life, were assessed. Qualitative interviews were conducted with people with dementia, family caregivers, and group and organizational leaders following intervention delivery, and the data were analyzed using the Consolidated Framework for Implementation Research. RESULTS: A total of 17 vCST group sessions with 59 participants were conducted for 7 weeks, with 53% (31/59) of participants attending all 14 sessions. Attrition rate was 7% (4/59), and outcome measure completion rate at follow-up was 68% (40/59). Interviews took place with 36 stakeholders. vCST was acceptable to participants and group leaders and enabled vital access to services during pandemic restrictions. While online services broadened geographic access, challenges emerged concerning inadequate computer literacy, poor technology access, and establishing interpersonal connections online. Exploratory, uncontrolled analyses indicated positive trends in quality of life but negative trends in cognition and activities of daily living, but these results were not statistically significant. CONCLUSIONS: vCST demonstrated feasibility and acceptability, serving as a crucial resource during the pandemic but raised challenges related to technology access, computer literacy, and long-term implementation. The study highlights the potential of vCST while emphasizing ongoing development and solutions to address implementation challenges.

RESUMO

OBJECTIVES: The implementation of pediatric oncology advanced practice nurse (s) roles in low- and middle-income countries (LMICs) presents opportunities and challenges. The authors explore the implications of pediatric oncology advanced practice nursing roles in Pakistan, Cameroon, Turkey, and Mexico. Potential benefits and drawbacks of advanced practice nursing roles, impacts on nursing care, and strategies for advanced practice nursing role development in LMIC settings are considered. METHODS: Information from scholarly articles, policy documents, and four LMIC pediatric oncology nurse expert perspectives on existing and imagined advanced practice nursing roles in pediatric oncology in LMIC were synthesized. RESULTS: Current literature and policies point to efforts across LMICs to establish a wide variety of advanced nursing practices, not necessarily aligned with internationally accepted advanced practice nursing standards of practice or education. The LMIC nurses describe a wide range of national general nurse education and government advanced practice nurse recognition/licensing. Challenges to achieving or strengthening advanced practice nursing roles include, for example, healthcare professional resistance, government unwillingness to recognize/license advanced practice nurses, and lack of advanced practice nursing faculty. To promote a pediatric oncology advanced practice nursing role in LMICs requires navigating the national nursing scope of practice and nursing culture. CONCLUSION: The strategic introduction of pediatric oncology advanced practice nursing roles in LMICs has the potential to significantly enhance patient care by, for example, addressing healthcare workforce shortages and facilitating timely care delivery. However, challenges related to role complexity, resistance from traditional healthcare structures, and role overlap must be considered. Tailoring these roles to local contexts and fostering stakeholder collaboration are essential for successful implementation. IMPLICATIONS FOR NURSING PRACTICE: The adoption of advanced practice nursing roles can lead to improved quality of care for pediatric oncology patients and their families in LMICs, where cancer care is challenging. The positive impact of pediatric oncology advanced practice nurses on patient outcomes and healthcare delivery cannot be discounted but must align with local nursing and healthcare culture and expectations.

RESUMO

BACKGROUND: Traffic-related crashes are a leading cause of premature death and disability. The safe systems approach is an evidence-informed set of innovations to reduce traffic-related injuries and deaths. First developed in Sweden, global health actors are adapting the model to improve road safety in low- and middle-income countries via technical assistance (TA) programs; however, there is little evidence on road safety TA across contexts. This study investigated how, why, and under what conditions technical assistance influenced evidence-informed road safety in Accra (Ghana), Bogotá (Colombia), and Mumbai (India), using a case study of the Bloomberg Philanthropies Initiative for Global Road Safety (BIGRS). METHODS: We conducted a realist evaluation with a multiple case study design to construct a program theory. Key informant interviews were conducted with 68 government officials, program staff, and other stakeholders. Documents were utilized to trace the evolution of the program. We used a retroductive analysis approach, drawing on the diffusion of innovation theory and guided by the context-mechanism-outcome approach to realist evaluation. RESULTS: TA can improve road safety capabilities and increase the uptake of evidence-informed interventions. Hands-on capacity building tailored to specific implementation needs improved implementers' understanding of new approaches. BIGRS generated novel, city-specific analytics that shifted the focus toward vulnerable road users. BIGRS and city officials launched pilots that brought evidence-informed approaches. This built confidence by demonstrating successful implementation and allowing government officials to gauge public perception. But pilots had to scale within existing city and national contexts. City champions, governance structures, existing political prioritization, and socio-cultural norms influenced scale-up. CONCLUSION: The program theory emphasizes the interaction of trust, credibility, champions and their authority, governance structures, political prioritization, and the implement-ability of international evidence in creating the conditions for road safety change. BIGRS continues to be a vehicle for improving road safety at scale and developing coalitions that assist governments in fulfilling their role as stewards of population well-being. Our findings improve understanding of the complex role of TA in translating evidence-informed interventions to country-level implementation and emphasize the importance of context-sensitive TA to increase impact.

RESUMO

Introduction: Data on medulloblastoma outcomes and experiences in low- and middle-income countries, especially in Latin America, is limited. This study examines challenges in Mexico's healthcare system, focusing on assessing outcomes for children with medulloblastoma in a tertiary care setting. Methods: A retrospective analysis was conducted, involving 284 patients treated at 21 pediatric oncology centers in Mexico. Results: High-risk patients exhibited markedly lower event-free survival than standard-risk patients (43.5% vs. 78.3%, p<0.001). Influential factors on survival included anaplastic subtype (HR 2.4, p=0.003), metastatic disease (HR 1.9, p=0.001); residual tumor >1.5cm², and lower radiotherapy doses significantly impacted event-free survival (EFS) and overall survival (OS). Platinum-based chemotherapy showed better results compared to the ICE protocol in terms of OS and EFS, which was associated with higher toxicity. Patients under 3 years old displayed notably lower OS and EFS compared to older children (36.1% vs. 55.9%, p=0.01).

RESUMO

BACKGROUND: Neonatal jaundice is a common condition that can lead to brain damage and disabilities when severe cases go undetected. Low- and middle-income countries often lack accurate methods for detecting neonatal jaundice and rely on visual assessment, resulting in a higher incidence of adverse consequences. Picterus Jaundice Pro (Picterus JP), an easy-to-use and affordable smartphone-based screening device for the condition, has demonstrated higher accuracy than visual assessment in Norwegian, Philippine and Mexican newborns. This study aimed to identify the barriers and facilitators to implementing Picterus JP in public health services in low-income settings in Mexico by exploring the current process of neonatal jaundice detection and stakeholders' perspectives in that context. METHODS: Qualitative data collection techniques, including one focus group, 15 semi-structured interviews and four observations, were employed in urban and rural health facilities in Oaxaca, Mexico. The participants included medical doctors, nurses and health administrators. The data were analysed by thematic analysis guided by the Consolidated Framework for Implementation Research. RESULTS: The analysis yielded four main themes: (I) the current state of neonatal care and NNJ detection, (II) the needs and desires for enhancing NNJ detection, (III) the barriers and facilitators to implementing Picterus JP in the health system and (IV) HCWs' expectations of Picterus JP. The findings identify deficiencies in the current neonatal jaundice detection process and the participants' desire for a more accurate method. Picterus JP was perceived as easy to use, useful and compatible with the work routine, but barriers to adoption were identified, including internet deficiencies and costs. CONCLUSIONS: The introduction of Picterus JP as a supporting tool to screen for neonatal jaundice is promising but contextual barriers in the setting must be addressed for successful implementation. There is also an opportunity to optimise visual assessment to improve detection of neonatal jaundice.

RESUMO

Clinical research is the cornerstone of improvements in cancer care. However, it has been conducted predominantly in high-income countries with few clinical trials available in Brazil and other low-and-middle-income countries (LMIC). Of note, less than one-third of registered clinical trials addressing some of the most commonly diagnosed cancers (breast, lung and cervical) recruited patients from LMIC in the last years. The Institute Project CURA promoted the fourth CURA meeting, discussing barriers to cancer clinical research and proposing potential solutions. A meeting was held in São Paulo, Brazil, in June 2023 with representatives from different sectors: Brazilian Health Regulatory Agency (Anvisa), National Commission of Ethics in Research (CONEP), non-governmental organisations, such as the Latin American Cooperative Oncology Group, the Brazilian Society of Clinical Oncology (SBOC), Contract Research Organisations, pharmaceutical companies and investigators. A total of 16 experts pointed out achievements as shortening the time of regulatory processes involving Anvisa and CONEP, development of staff training programs, maintenance of the National Program of Oncological Attention (PRONON), and the foundation of qualified centres in North and Northeast Brazilian regions. Participants also highlighted the need to be more competitive in the field, which requires optimising ongoing policies and implementing new strategies as decentralisation of clinical research centres, public awareness campaigns, community-centered approaches, collaborations and partnerships, expansion of physicians-directed policies, exploring the role of the steering committee. Active and consistent reporting of the initiatives might help to propagate ongoing advances, increasing Brazilian participation in clinical cancer research. Engagement of all players is crucial to maintain continuous progress with further improvements in critical points including regulatory timelines and increments in qualified human resources which aligned with new educational initiatives focused on physicians and the general population will expand access to cancer clinical trials in Brazil.

RESUMO

BACKGROUND: High-dose chemotherapy followed by stem cell transplant (HDCT) is potentially curative for patients with refractory germ cell tumors (rGCT). There is scarce real-world data supporting its implementation in low- and middle-income countries. We described the experience of our tertiary cancer center in Sao Paulo, Brazil. METHODS: We identified male patients ≥18 years-old with rGCT referred to HDCT after board discussion. Clinical data, including delays in HDCT protocol, were extracted from medical records, and survival outcomes were estimated using the Kaplan-Meier method. The log-rank test and Cox proportional hazard were used to determine effects on overall survival (OS). RESULTS: From January 2013 to January 2023, 34 patients were referred and considered eligible to receive 2 cycles of HDCT. Most patients had primary testicular tumors (82%), nonseminomatous histology (88%), and poor International Germ Cell Collaborative Group (IGCCCG) (79%). Twenty-three patients received HDCT (1 cycle, n = 8; 2 cycles, n = 15). Main reasons for not receiving any HDCT were death due to progressive disease (n = 1), performance deterioration (n = 7), and failure of stem cell mobilization (n = 3). OS at 2 years was 36.7% for the eligible population, 56.1% for patients who underwent at least 1 HDCT, and 77.1% for those who had ≥2 cycles. The 2-year OS rate for patients not given HDCT was 0%. All patients had delays in protocol, and poor-risk patients had longer intervals from referral to protocol initiation (0.7 vs. 1.8 month, P < .01). CONCLUSION: Outcomes of patients who received ≥1 HDCT were encouraging; however, only 15 from 34 eligible patients were able to receive the planned 2 cycles of HDCT. Further strategies to minimize treatment delays in low- and middle-income countries are needed.

RESUMO

Breast cancer remains a significant cause of death for women globally, despite advancements in detection and treatment, low- and middle-income countries face unique obstacles. Role of Research Working Group (RWG) can expedite research progress by fostering collaboration between scientists, clinicians, and stakeholders. Benefits of a Global RWG include pooling resources and expertise to develop new research ideas, addressing disparities, and building local research capacity, with the potential to improve breast cancer research and outcomes.

RESUMO

Objectives: Primary graft failure (pGF) after hematopoietic stem-cell transplant is associated with considerable morbidity and mortality. The incidence in haplo-HSCT has been reported to be between 0% and 30%. In 2018, we identified a pGF incidence of 35% in our pediatric haplo-HSCT recipients with hematologic malignancies, which motivated us to enact changes to the conditioning regimen.Methods: We performed a single-center prospective, pre-post study of consecutive patients under 16 years with hematologic malignancies, from January 2015 to December 2022 who received a haplo-HSCT. Twenty-six pediatric patients received a haplo-HSCT before September 2018 (G1) and 36 patients after (G2). The main conditioning regimen for G1 was myeloablative with Flu/Cy/Bu, and for G2 the main regimen was reduced intensity Flu/Cy/Mel/TBI2.Results: Nine patients (35%) in G1 had primary graft failure, while in G2 there were no patients with pGF. The median follow-up for G1 was 15.9 months, and for G2 was 24.8 months, with an estimated overall survival at 12 months of 63% (95% CI 47-76) versus 85% (95% CI 73-93), and at 24 months of 47% (95% CI 31-64) versus 70% (95% CI 54-82) respectively (p = .007).Conclusion: After September 2018 conditioning regimen modifications were implemented with the objective of reducing primary failure, consisting mainly of switching from busulfan to melphalan as the alkylating agent of choice, and adding, when clinically possible TBI. Primary failure has been significantly reduced in our institution since then.
