Unidentified patients pose challenges in emergency care due to missing clinical history and identification, impacting patient safety and decision-making. Despite known risks, little is understood about this group in middle-income countries. To describe the epidemiological profile and the clinical, structural, and social challenges that influence the care of unidentified patients in a public teaching hospital. This retrospective cohort study was conducted from January 2019 to December 2022 in the emergency department (ED) of a public teaching hospital in Belo Horizonte, Brazil. Data from unidentified patients were extracted from electronic medical records, including demographics, admission reasons, risk classification, clinical management, outcomes, and hospital length of stay. Multivariate logistic regression was used to identify factors associated with adverse outcomes, adjusting for clinical and sociodemographic variables. Among 2,425 unidentified ED admissions, 332 cases were sampled using a finite population correction formula. Of these, 81.6% were male; median age was 32years (interquartile range 26-43). Main admission causes were physical assault (39.8%), falls (20.5%), and road traffic collisions (10.8%); 69.9% were triaged as very urgent. Only 29.2% were identified before discharge; time as unidentified ranged from 0 to 411days (median 1 day). Remaining unidentified beyond one day was strongly associated with adverse outcomes (odds ratio 8.56; 95% confidence interval 5.0-14.6; p < .001). Delayed identification was associated with adverse outcomes, but causality cannot be inferred. Early identification initiatives should be combined with broader strategies to address underlying risks and ensure continuity of care.

This article aims to disseminate the potential of bamboo as a raw material for the development and production of artifacts that contribute to productive and social life in peripheral urban communities. The research, carried out as part of a master's degree in Design, was conducted in the communities of Confisco and Coqueiros, in Belo Horizonte, Minas Gerais, Brazil, which are characterized by high socioeconomic vulnerability. It was identified that local artisans faced difficulties in marketing their products due to the high cost of renting traditional market stalls. Given this context, a stall was developed based on eco-design principles, using Phyllostachys aurea bamboo, with the following characteristics: low cost, demountable, compact, durable, easy to assemble, and capable of being produced with simple tools by the artisans themselves. The project included training workshops on bamboo craft techniques for manufacturing stalls, promoting learning and empowerment among participants. Although still ongoing, partial results indicate that the initiative can promote environmental awareness, critical thinking, and community strengthening, in addition to increasing the productive and economic autonomy of artisans, especially among Black women from low-income neighborhoods with limited formal education.

To describe a surgical technique for four-point Gore-Tex scleral fixation of a foldable hydrophilic acrylic intraocular lens (IOL) with integrated eyelets (UnA IOL; Mediphacos, Belo Horizonte, Brazil) and report its postoperative outcomes. A 62-year-old woman presented with persistent monocular diplopia after cataract surgery with in-the-bag implantation of a three-piece IOL. Examination revealed IOL decentration secondary to zonular dialysis exceeding 120°, accompanied by iridodonesis. The unstable IOL was explanted, and pars plana vitrectomy was performed, followed by implantation of the UnA IOL using a four-point Gore-Tex CV-8 scleral fixation technique. Monocular diplopia resolved entirely on the postoperative day, and best-corrected visual acuity improved from 20/30 preoperatively to 20/20 at one month, with the IOL well centered and stable on ultrasound biomicroscopy. No suture erosion, persistent inflammation, ocular hypertension, or macular edema was observed, and the UnA IOL remained well-centered and stable during the 6-month follow-up. Four-point Gore-Tex scleral fixation using the UnA IOL demonstrated excellent centration, stability, and safety in the setting of significant zonular loss. Its purpose-built design, foldability, and accessibility make it a practical alternative for secondary IOL implantation in eyes lacking adequate capsular support.

Abstract This study examines the environmental and social implications of replacing diesel buses with battery-electric buses in Belo Horizonte, Brazil, through a clearly defined research question and an analytical framework grounded in emission-accounting methodology and social impact indicators. Environmentally, the avoided emissions were estimated using GHG Protocol-based factors and include uncertainty ranges to account for variability in fuel composition, electricity-grid intensity, and annual fleet mileage. The results indicate that full electrification of the municipal fleet could avoid 125,414 t of CO 2 emissions per year, with sensitivity analysis showing a ± 10% variation depending on operational and energy-mix assumptions. Additionally, 7.8 t of CH 4 and 7.4 t of N 2 O emissions could be avoided annually. Social impacts are assessed using secondary indicators related to air quality exposure, noise reduction, accessibility, and mobility equity, highlighting measurable co-benefits for public health and urban inclusion. By integrating environmental and social dimensions, the study contributes empirical evidence to ongoing debates on sustainable urban transport transitions in metropolitan contexts.

Helicobacter pylori is a major causative agent of chronic gastritis, gastric and duodenal ulcers, gastric cancer, and mucosa-associated lymphoid tissue lymphoma. Transmission to humans may occur through the consumption of contaminated food. This study investigated the prevalence of H. pylori in fresh raw meat from different animal sources and assessed the efficiency of selective media for its recovery in Dhamar Governorate, Yemen. A total of 380 meat samples, including beef (n = 125), sheep (n = 135), and goat (n = 120), were collected from slaughterhouses (n = 127), retail markets (n = 124), and butcher shops (n = 129). Three selective media: Modified Campy-blood Agar (MCA), Belo Horizonte Agar (BHA), and Egg Yolk Emulsion (EYE) medium were evaluated for comparative recovery from each meat source. Overall, H. pylori was detected in 47 samples (12.4%), with a relatively high prevalence in beef (15.2%), followed by goat (12.5%) and sheep (9.6%). By source, butcher shop samples comparatively showed the highest prevalence (15.5%), especially in beef (19.1%), goat (14.3%), and sheep (13.3%), as compared to the slaughterhouses (11.8%) and retail markets (9.7%). Differences among meat types and sources were not statistically significant (p = 0.394 and p = 0.362). Overall, selective media comparison revealed that MCA showed a relatively high recovery rate (6.6%), followed by EYE (3.4%) and BHA (2.4%). A seasonal trend was observed, with peak prevalence in April (20%). These findings suggest that raw meat may represent a potential source of exposure to H. pylori, although its role in transmission to humans remains to be fully clarified. Regular monitoring, improved hygiene practices, and stricter control of environmental contamination are recommended to reduce associated public health risks.

ABSTRACTBackgroundCandida (Candidozyma) auris is an emerging yeast that poses a significant global health threat due to its multidrug resistance and ability to cause healthcare‐associated outbreaks. Genomic surveillance is essential for monitoring spread, transmission and antifungal resistance.ObjectivesTo report the first identification and genomic characterisation of C. auris in the state of Minas Gerais, Southeast Brazil, and to investigate the genetic origin and diversity, resistance‐associated mutations, and potential transmission dynamics during a hospital outbreak.MethodsEight C. auris isolates were collected during a hospital outbreak in Belo Horizonte, Minas Gerais, Brazil, including clinical samples from patients and environmental samples from surfaces in the Intensive Care Unit (ICU). Epidemiological investigation, whole‐genome sequencing (WGS) and phylogenomic analyses were conducted to determine circulating clade, genetic diversity, outbreak origin and the presence of antifungal resistance mutations.ResultsAll isolates were classified as clade IV and exhibited high genomic similarity to strains previously reported in northern Colombia (Caribbean coast). One isolate carried the ERG11 Y132F mutation, associated with fluconazole resistance, but this mutation was absent in another isolate from the same patient collected 1 day earlier, indicating mixed fungal populations. Environmental isolates clustered tightly with clinical strains, supporting surface‐mediated transmission in the ICU.ConclusionsThis study describes the introduction and local spread of clade IV C. auris in Minas Gerais, Brazil. The findings underscore the critical role of genomic surveillance in identifying resistance mechanisms, tracing transmission pathways and guiding public health responses.

Self-perceived skills in the diagnosis of hospital malnutrition, medical knowledge, and interest in nutrition: A cross-sectional study of medical residency programs.

ABSTRACT This paper explores the intertwined relationship between urban planning, the genealogy of racial property regimes, and residential segregation in postcolonial urban contexts. Through the lens of racial capitalism, the study revisits the history of Nova Lima to reveal the origins of a racial property regime and its enduring impact on contemporary land ownership and planning practices. Nova Lima, an affluent city in the Belo Horizonte metropolitan area (Brazil), faces mounting pressure from real estate interests, the mining industry, and environmental crises. The study sheds light on global dynamics at the intersection of capital, space, and race, while challenging the colorblind narratives often perpetuated in urban planning discourses and practices. By linking the history of racialized urban processes with contemporary planning frameworks, the paper examines current planning and zoning regulations to uncover how policy decisions either reinforce or intentionally sustain socio-spatial inequalities through unproblematized or desired white spatial segregation.

Belo Horizonte’s right-to-food model has been recognized as a pioneering approach to urban food security, significantly contributing to the reduction of hunger and the promotion of social equity. This study analyzes the linkages between the city’s food security policies and the Sustainable Development Goals (SDGs), highlighting their impact on poverty reduction, public health, and economic sustainability. The research demonstrates that Belo Horizonte’s integrated food policies, including subsidized food programs, urban agriculture, and multi-stakeholder collaboration, have provided cost-effective and scalable solutions to urban food insecurity. Despite its success, challenges remain regarding policy sustainability, financial constraints, and political continuity. This study also identifies key limitations, including reliance on secondary data and the need for more field-based evaluations. Future research should explore comparative analyses between Belo Horizonte and other urban food security models, assessing their long-term economic and environmental impacts. The findings offer valuable insights for policymakers, urban planners, and researchers interested in developing sustainable and equitable food systems in cities worldwide.

Metro systems are high-capacity urban rail networks designed to provide fast, reliable, and efficient transportation. This article presents a comparative benchmarking study of six leading metro systems in Brazil and six prominent international cases, aiming to identify best practices and recurring challenges based on key operational, planning, design, governance, and performance indicators. The Brazilian systems analyzed are located in Rio de Janeiro, São Paulo, Belo Horizonte, Fortaleza, Recife, and Salvador, while the international cases include London, Paris, Tokyo, Berlin, New York, and Madrid. The methodology combined documentary research with technical analysis of public data sources, institutional reports, and performance indicators. The results reveal significant contrasts in network scale, operational efficiency, governance models, funding mechanisms, and integration with urban planning. São Paulo’s system stands out for its network robustness, automation, and consolidated monitoring framework, while other Brazilian cities face limitations in service coverage and financial sustainability. The international cases offer valuable insights into fare integration, the use of emerging technologies, and the application of performance metrics to foster more sustainable and efficient high-capacity urban transit systems. The findings provide relevant evidence to support policymakers, transport authorities, and urban planners in improving the planning, management, and sustainability of high-capacity urban transit systems.

This study investigates parcel delivery patterns in Belo Horizonte, Brazil, to elucidate the influence of spatial inequalities, urban structure, socioeconomic factors, and retail diversity on delivery demand, employing spatial regression models. The results reveal that income and retail diversity positively impact parcel delivery, while food deserts drive increased reliance on e-commerce due to limited local options. In particular, the distance from the city center negatively affects delivery patterns, highlighting spatial inequities. Areas characterized by social inequalities exhibit greater delivery activity, highlighting e-commerce as a vital alternative where local services are scarce. These findings advocate for integrated urban planning policies that strategically leverage parcel delivery services to achieve more equitable access, address service gaps, and foster delivery expansion in marginalized areas.

Abstract Background The objective of our study is to answer two questions: 1) what is the mortality due to Candidemia in a general hospital of a developing country? 2) is it possible to build an accurate model to predict mortality after Candidemia?Table 1Candida species causing Candidemia.The vast majority of candidemia cases (82%) were caused by just three Candida species: albicans, tropicalis, and parapsilosis.Table 2In-hospital mortality by Candida species.There was no significant difference in mortality among the Candida species. Methods This single-center retrospective cohort study was conducted between Nov/2019-Oct/2024, involving patients with bloodstream infection caused by Candida species admitted to an Intensive Care Unit of a hospital in Belo Horizonte, a city with approximately three million inhabitants in Brazil. Occurrence of in-hospital mortality was calculated using point estimation and a 95% confidence interval. Subsequently, univariate and multivariate analyses were performed to identify factors associated with in-hospital mortality.Table 3Univariate analysis of quantitative variables to identify factors associated with in-hospital death due to candidemia.Patients who progressed to death were significantly older and had a greater intrinsic severity of illness.Table 4Multivariate analysis (using logistic regression) to identify factors associated with in-hospital mortality due to candidemia.In the multivariate analysis, age and SOFA score independently explain why some patients progress to death and others are discharged. Results A sample of 60 patients with bloodstream infection caused by Candida (candidemia) was evaluated between November 2019 and October 2024: 50% were between 70 and 80 years old, with a mean age of 66 ±15 years. The vast majority of candidemia cases (82%) were caused by just three Candida species: albicans, tropicalis, and parapsilosis (Table 1). For the treatment, 56% of the cases received Anidulafungin, 29% Fluconazole, 7% Liposomal Amphotericin B, 5% Micafungin, and 2% Voriconazole. In total, 50 patients progressed to in-hospital death, resulting in a global mortality rate of 83% (95% CI = [71.5%; 91.7%]). There was no significant difference in mortality among the Candida species (Table 2). Patients who progressed to death were significantly older and had a greater intrinsic severity of illness (Table 3). In the multivariate analysis (Table 4), age and SOFA score independently explain why some patients progress to death and others are discharged. The ROC curve considering the logistic regression model for in-hospital death prediction presented a fair predictive ability, with an area under the curve = 0.75 (95% CI = [0.63; 0.87]). Conclusion Single-center Brazilian ICU study found 83% in-hospital candidemia mortality. Older age and SOFA score predicted death independently. Logistic model showed fair mortality prediction (AUC 0.75) for risk stratification, highlighting candidemia's burden and the importance of age/severity in prognosis.

Abstract Background Recognizing sepsis as a critical driver of unexpected mortality in both emergency department and inpatient settings, our study seeks to construct a robust model capable of automatically predicting sepsis throughout the continuum of care.Table 1Impact of Sepsis on Mortality: Sepsis patients exhibited a significantly higher risk of death compared to non-sepsis patients. Sepsis had a devastating impact: 29.4% of sepsis patients died, representing a 44-fold higher relative risk compared with those without sepsisFigure 1Box-Plot showing the impact of sepsis on the length of hospital stays. Despite the enormous variability, the length of hospital stay was significantly higher in sepsis cases, with a median of 14 days, compared with a median of one day for non-sepsis patients Methods Single-center retrospective cohort study (Jan 2024-Mar 2025) of all emergency department or admitted patients at a public hospital in Belo Horizonte, Brazil (∼3M pop.). Sepsis: positive blood culture OR physician-documented clinical diagnosis (ICD-10 A40/A41). Multivariate logistic regression determined independent sepsis predictors, including 59 exam/assay requests (present/absent during care). The model built was made available as an application within the Datamart A.R.G.U.S.—Assistant for Recovery and Guarding of Urgent and Epidemiological Sentinels—a cloud-based platform hosted on AWS and developed by our team that integrates patient Electronic Medical Records.Table 2Independent predictors of sepsis identified by multivariate logistic regression among requested exams, assays, or procedures. The stepwise logistic regression model identified 10 exams, assays, or procedures that, when requested for a patient, demonstrate high predictive ability for sepsis.Figure 2ROC (Receiver Operating Characteristic) curves evaluating the predictive performance of the logistic regression model built to predict sepsis. The stepwise logistic regression identified 10 readily available exams, assays, or procedures that exhibit high predictive ability for sepsis when requested during a patient's continuum of care Results A total of 162,537 patients evaluated in the emergency department or admitted to the hospital: 974 sepsis cases (0.6% risk); 250 cases (26% of sepsis cases) were identified as clinically diagnosed sepsis based solely on ICD-10 codes; 38 cases (4% of sepsis cases) received an ICD-10 sepsis code and had a positive blood culture; and 686 cases (70% of sepsis cases) had a positive blood culture. Sepsis had a devastating impact: 29.4% of sepsis patients died, representing a 44-fold higher relative risk compared with those without sepsis (Table 1). Despite the enormous variability (Fig. 1), the length of hospital stay was significantly higher in sepsis cases, with a median of 14 days, compared with a median of one day for non-sepsis patients. Patients were randomly split into two subsets: 113,424 patients for modeling and 49,113 for validating the logistic model. The stepwise logistic regression model identified 10 exams, assays, or procedures (Table 2) that, when requested for a patient, demonstrate high predictive ability for sepsis (Fig. 2). Conclusion Low 0.6% sepsis incidence in a Brazilian hospital contrasted with catastrophic 29.4% mortality (44x higher RR) and prolonged LOS (14 vs 1 day). Logistic regression identified 10 predictive exams/assays, part of a larger effort to optimize the Hospital Infection Control Service's sepsis protocol.

ABSTRACTDengue poses a significant arboviral threat in Brazil, with 2024 recording the largest outbreak to date. This prospective observational study was conducted during the 2024 outbreak with unvaccinated patients at Eduardo de Menezes Hospital, Belo Horizonte. A total of 556 patients were included, of whom 169 had complete clinical and laboratory data. Patients with suspected dengue underwent clinical and hematological evaluations, as well as diagnosis by RT‐qPCR, and ELISA. These parameters were employed to assess the relationship between diagnostic methods, hematological changes, and disease severity. RT‐qPCR confirmed dengue infection in 60% of with clinical symptoms, with partial overlap between PCR positivity and IgM detection, reflecting time‐dependent diagnostic windows. High IgG seropositivity indicated widespread prior exposure in the population. Thrombocytopenia was the most consistent hematological finding, with platelet counts declining until day 8 of symptoms and recovering around day 10; a secondary decline was observed in some patients with prolonged hospitalization. No significant differences in clinical severity were observed across serotypes, although DENV‐2 showed a trend toward lower platelet counts. These findings highlight the importance of integrating molecular and serological diagnostics during outbreaks and reinforce platelet monitoring as a key parameter for identifying patients at risk of severe dengue.

To investigate the clinical, epidemiological, and laboratory profile of people with tuberculosis. This was an observational clinical-epidemiological cohort study of people with tuberculosis treated at the Secondary Referral Outpatient Clinic of the Hospital das Clínicas of the Federal University of Minas Gerais, from January 2013 to August 2021. The cases were evaluated from the diagnosis onward and followed after entry into the outpatient clinic until the second month of treatment, as well as at the end of treatment. Data were collected through interviews and/or review of medical records, the Notifiable Health Conditions Information System, and the Special Tuberculosis Treatment Information System. A total of 227 cases were identified: 40.1% with pulmonary tuberculosis, 50.7% with extrapulmonary tuberculosis, and 9.2% with both forms. At the first visit, the main symptom among those with pulmonary tuberculosis was cough (76.9%); in extrapulmonary tuberculosis, symptoms were associated with the affected organ; and in pulmonary and extrapulmonary tuberculosis, anorexia was reported in 47.6% of cases. The most frequent comorbidity was diabetes (20.7%). By the end of the second month, clinical, laboratory, and radiological improvement was observed. Treatment outcome was cure in 92.5% of cases, and directly observed treatment was performed in 7.6%. Extrapulmonary tuberculosis was the most frequent form, directly observed treatment was rarely implemented, and the cure rate was high. Determining population profiles in Secondary Referral Centers identifies outcomes that may indicate the quality of care provided.

The Cultural Exhibition, held annually between September and October, serves as a valuable space for reflection and debate on relevant social issues, aiming to contribute to student education. This paper presents the project's conception and development, the references used by students, the involvement of the school community. The results indicate that there was great student participation, enabling reflections and discussions about ethnic-racial relations, gender and work in Brazil.

This article aimed to report on the process of producing an animated video, using aesthetic and synthetic language, on Good Food Handling Practices (GFHP) and attribution of meanings to the work of food handlers in public educational institutions in a Brazilian metropolis. This process was composed of a survey of conceptions about GFHP and an attribution of meaning to the craft of a representative sample of food handlers in public educational institutions in Belo Horizonte, state of Minas Gerais, Brazil, which provided input to produce the video. This study advocates the use of animated video as a strategy with the potential to engender processes that favor the construction of knowledge about GFHP and the attribution of meaning to the craft of food handlers, related to the recognition of their role as educators.
