ABSTRACT

INTRODUCTION: This study sought to analyze the relationships between cutaneous leishmaniasis and its epidemiological, environmental and socioeconomic conditions, in the 22 microregions of Pará state, Brazil, for the period from 2017 to 2022. METHODOLOGY: In this ecological and exploratory study, the microregions were used as spatial units because they are formed by contiguous municipalities with similar characteristics. The epidemiological, environmental, socioeconomic, and public health policy data employed were obtained from the official information systems at the Ministry of Health, National Institute for Space Research, and Brazilian Institute of Geography and Statistics. A fuzzy system was developed to identify risk factors for the disease, using Python programming language. The results were analyzed with the bivariate Global Moran spatial analysis technique. RESULTS: It was observed that the Altamira microregion had the highest risk percentage for the disease, while Breves had the lowest, with significant differences in the relevance of its conditioning factors, mainly related to land use and cover patterns, in addition to demography and living conditions index, education and public health policies. CONCLUSIONS: The fuzzy system associated with the geostatistical technique was satisfactory for identifying areas with health vulnerability gradients related to deforestation, pasture, poverty, illiteracy, and health services coverage, as its conditioning variables. Thus, it was demonstrated that deforestation was the main risk factor for the disease. The system can also be used in environmental and epidemiological surveillance.

ABSTRACT

Introduction: The purpose of this study was to investigate the ideal training load to be applied during periods of fixture congestion to ensure an adequate dose-response effect for performance maintenance. Methods: Match performance data and corresponding pre-match training load sessions (both N = 498 match performance cases and training-block session cases) were collected (with the catapult system, VECTOR7) from 36 male professional soccer players (23.5 ± 5.2 years; 178 ± 4 cm; 75.5 ± 6.0 kg) belonging to the Brazilian First Division team during the 2022 season. The following data were collected in match and training sessions: jump, acceleration, deceleration, and change of direction (COD); running distance producing metabolic power at different intensities (>20, >20-35, >35-45, >45-55, and >55 W kg-1), total distance (m), relative distance (m/min), running distance at different speeds (>20, >25, and >30 km/h), number of sprints (running >25 km/h), and maximum speed (km/h). Mixed linear model (MLM), decision tree regression (DTR), and cluster K means model (SPSS v.26) approach were performed to identify the most critical variables (and their respective load) in the training sessions that could explain the athlete's match performance. Results: MLM and DTR regression show that training load significantly affects game performance in a specific way. According to the present data, an interference phenomenon can occur when a high load of two different skills (running in a straight line vs COD, deceleration, and jumping) is applied in the same training block of the week. The cluster approach, followed by a chi-squared test, identified significant associations between training load and athlete match performance in a dose-dependent manner. Discussion: The high load values described here have a beneficial effect on match performance, despite the interference between stimuli discussed above. We present a positive training load from a congested season from the Brazilian First Division team. The study suggests that an interference effect occurs when high physical training loads are applied to different specific physical skills throughout the season.

ABSTRACT

New technologies based on virtual reality and augmented reality offer promising perspectives in an attempt to increase the assessment of human kinematics. The aim of this work was to develop a markerless 3D motion analysis capture system (MOVA3D) and to test it versus Qualisys Track Manager (QTM). A digital camera was used to capture the data, and proprietary software capable of automatically inferring the joint centers in 3D and performing the angular kinematic calculations of interest was developed for such analysis. In the experiment, 10 subjects (22 to 50 years old), 5 men and 5 women, with a body mass index between 18.5 and 29.9 kg/m2, performed squatting, hip flexion, and abduction movements, and both systems measured the hip abduction/adduction angle and hip flexion/extension, simultaneously. The mean value of the difference between the QTM system and the MOVA3D system for all frames for each joint angle was analyzed with Pearson's correlation coefficient (r). The MOVA3D system reached good (above 0.75) or excellent (above 0.90) correlations in 6 out of 8 variables. The average error remained below 12° in only 20 out of 24 variables analyzed. The MOVA3D system is therefore promising for use in telerehabilitation or other applications where this level of error is acceptable. Future studies should continue to validate the MOVA3D as updated versions of their software are developed.

ABSTRACT

Peritoneal metastases (PM) occur when cancer cells spread inside the abdominal cavity and entail an advanced stage of colorectal cancer (CRC). Prognosis, which is poor, correlates highly with tumour burden, as measured by the peritoneal cancer index (PCI). Cytoreductive surgery (CRS) in specialized centres should be offered especially to patients with a low to moderate PCI when complete resection is expected. The presence of resectable metastatic disease in other organs is not a contraindication in well-selected patients. Although several retrospective and small prospective studies have suggested a survival benefit of adding hyperthermic intraperitoneal chemotherapy (HIPEC) to CRS, the recently published phase III studies PRODIGE-7 in CRC patients with PM, and COLOPEC and PROPHYLOCHIP in resected CRC with high-risk of PM, failed to show any survival advantage of this strategy using oxaliplatin in a 30-min perfusion. Final results from ongoing randomized phase III trials testing CRS plus HIPEC based on mitomycin C (MMC) are awaited with interest. In this article, a group of experts selected by the Spanish Group for the Treatment of Digestive Tumours (TTD) and the Spanish Group of Peritoneal Oncologic Surgery (GECOP), which is part of the Spanish Society of Surgical Oncology (SEOQ), reviewed the role of HIPEC plus CRS in CRC patients with PM. As a result, a series of recommendations to optimize the management of these patients is proposed.

ABSTRACT

Evaluating the outcomes and tracking the trajectory of biodiversity offsets is essential to demonstrating their effectiveness as a mechanism to conciliate development and conservation. We reviewed the literature to determine the principles that should underpin biodiversity offset planning and the criteria for offset evaluation at the project level. According to the literature, the core principles of equivalence, additionality, and permanence are used as criteria to evaluate conservation outcomes of offsets. We applied the criteria to evaluate offsets of a large iron ore mining project in the Atlantic Forest in Brazil. We examined equivalence in terms of the amount of area per biodiversity value affected and fauna and flora similarity, additionality in terms of landscape connectivity, and permanence in terms of guarantees to ensure protection and restoration offsets lasting outcomes. We found an offset ratio (amount of affected area:offset area) of 1:1.8 for forests and 1:2 for grasslands. Ecological equivalence (i.e., similarity between affected and offset areas) was found for forested areas, but not for ferruginous rupestrian grasslands or for fauna. Landscape metrics showed that connectivity improved relative to the preproject situation as a result of locating restoration offsets in the largest and best-connected forest patch. Permanence of offsets was addressed by establishing covenants and management measures, but financial guarantees to cover maintenance costs after mine closure were lacking. Offsets should be equivalent in type and size, provide conservation outcomes that would not be obtained without them (additionality), and be lasting (permanence). To monitor and evaluate offsets, it is necessary to determine how well these 3 principles are applied in the planning, implementation, and maintenance of offsets. Achieving measurable conservation outcomes from offsets is a long-term endeavor that requires sustained management support, and is information intensive. Thus, offsets require ongoing monitoring and evaluation as well as adaptive management.


Evaluación del potencial de las compensaciones por biodiversidad para obtener ganancias netas Resumen La evaluación de resultados y el rastreo de la trayectoria de las compensaciones por biodiversidad son esenciales para demostrar su efectividad como mecanismo de conciliación entre el desarrollo y la conservación. Revisamos la literatura para determinar los principios que deberían sustentar los planes de compensación y los criterios para evaluarla a nivel de proyecto. Según la literatura, se usan los principios nucleares de equivalencia, adicionalidad y permanencia como criterio para evaluar los resultados de conservación de las compensaciones. Aplicamos este criterio para evaluar las compensaciones de un gran proyecto minero de mineral de hierro en el Bosque Atlántico de Brasil. Analizamos la equivalencia en términos de cantidad de área por valor de biodiversidad afectado y similitudes entre la flora y fauna; la adicionalidad en términos de conectividad de paisaje; y la permanencia en términos de las garantías que aseguran que las compensaciones tengan resultados longevos de restauración y protección. Descubrimos una proporción en las compensaciones (cantidad del área afectada:área de compensación) de 1:1.8 para los bosques y de 1:2 en los campos naturales. Encontramos equivalencias ecológicas (es decir, la similitud entre las áreas afectadas y las de compensación) para las áreas boscosas, pero no para los campos rupestres ferruginosos ni para la fauna. Las medidas del paisaje mostraron que la conectividad mejoró en relación a la situación previa al proyecto gracias a la ubicación de las compensaciones por restauración en los fragmentos de bosque más grandes y mejor conectados. Establecimos Contractos y medidas de manejo fueron establecidos la permanencia de las compensaciones, pero las garantías económicas para cubrir los costos de mantenimiento después del cierre de la mina no están suficientemente garantizadas. Las compensaciones deberían ser iguales en tipo y tamaño (equivalencia), proporcionar resultados de conservación que no se obtendrían en su ausencia (adicionalidad) y ser duraderas (permanencia). Se necesita determinar cómo se aplican estos tres principios en la planeación, implementación y mantenimiento de las compensaciones para poder monitorearlas. Si se quieren lograr resultados medibles de conservación, se necesita que el manejo cuente con un apoyo mantenido y a largo plazo que contenga con información intensiva. Por lo tanto, las compensaciones requieren un monitoreo y evaluación continua además del manejo adaptativo.

ABSTRACT

This study aims to report what motivates individuals to be physically active, to determine whether motivating factors influence physical activity (PA) levels, and whether this differs across the lifespan. This is a cross-sectional study with 498 individuals: 117 adolescents, 306 adults, and 75 older adults. PA was assessed using Baecke's questionnaire, and motivating factors for practicing sports were investigated using a scale with twelve questions. The factor analysis identified three motivating factors for sports practice: psychosocial, bodily, and well-being. The scale's overall reliability and internal consistency indicated a Cronbach's alpha of 0.885. The analysis of covariance (ANCOVA) adjusted for sex indicated the three factors as having a significant effect on PA (p < 0.050); however, only the well-being factor showed a significant interaction with age groups (p = 0.023, ηp2 = 0.030). Subsequently, the effect of the well-being factor on PA scores in each age group was explored through regression analyses. Only older adults showed a significant association in the unadjusted [OR = 0.378, p = 0.001, R2 = 0.243] and the sex-adjusted analysis [OR = 0.377, p = 0.001, R2 = 0.288]. These results help us to better understand the underlying motivational reasons in different age groups for engaging in sports.

ABSTRACT

Abstract Hemodialysis central venous catheter (CVC) insertion can be complicated in patients with anomalous vessel anatomy. In such cases detailed knowledge of thoracic vessel anatomy is necessary to identify the exact location of the catheter. Central venous placement under ultrasound control has significantly reduced the complications associated with blind puncture and allows an appropriate puncture of the desired vessel, but the CVC can still get misplaced if it follows an anomalous route. Herein, we report a case of dialysis catheter placed into a left sided superior vena cava, only diagnosed after CT scan study.


Resumo A inserção do cateter venoso central (CVC) para hemodiálise pode ser complicada em pacientes com anatomia anômala dos vasos. Nesses casos, o conhecimento detalhado da anatomia do vaso torácico é necessário para identificar a localização exata do cateter. A colocação venosa central sob controle de ultrassom tem reduzido significativamente as complicações associadas à punção às cegas e permite uma punção apropriada do vaso desejado, mas o CVC ainda pode ficar mal posicionado se seguir uma rota anômala. Aqui, relatamos um caso de cateter de diálise colocado em uma veia cava superior esquerda, apenas diagnosticado após estudo de tomografia computadorizada.

ABSTRACT

Reducing phosphate fertilizer inputs while increasing food nutritional quality has been posited as a major challenge to decrease human undernourishment and ensure food security. In this context, quinoa has emerged as a promising crop due to its ability to tolerate different stress conditions and grow in marginal soils with low nutrient content, in addition to the exceptional nutritional quality of its grains. However, there is scarce information about the phosphorus acquisition capacity of quinoa roots. This work aimed to provide new insights into P acquisition and functional root traits, such as root biomass, rhizosphere pH, carboxylate exudation, and acid phosphatase activity of thirty quinoa genotypes grown under P limiting conditions (7 mg P kg-1). Significant genotypic variation was observed among genotypes, with average P accumulation ranging from 1.2 to 11.8 mg. The shoot biomass production varied more than 14 times among genotypes and was correlated with the P accumulation on shoots (r = 0.91). Despite showing high variability in root traits, only root biomass production highly correlated with P acquisition (r = 0.77), suggesting that root growth/morphology rather than the measured biochemical activity possesses a critical role in the P nutrition of quinoa.

ABSTRACT

This study aimed (1) to investigate the association between body mass index (BMI), physical activity (PA), and physical function (PF) with health-related quality of life (HRQoL), and (2) to examine in-depth whether PA and PF mediate the relationship between BMI and HRQoL in older adults. We investigated 802 individuals (mean age 69.8 ± 5.6 years), residents of the Autonomous Region of Madeira, Portugal. Harmol and PA were assessed using the SF-36 and Baecke questionnaires, respectively, and PF by the Senior Fitness Test. The prevalence of overweight was 71.3%, 26.5% for normal weight, and 2.1% for underweight. We verified a small correlation between age and sex with BMI, PA, PF, and medium borderline with HRQoL. After adjusting for covariates (i.e., sex, age, comorbidities), the multivariate regression analysis indicated a 93.1% chance of improvement in HRQoL for low BMI, while PA and PF revealed a chance of increasing HRQoL by 91.8% and 60.0%, respectively. According to the serial mediation pathway, PA and PF partially mediated the association between BMI and HRQoL by 32.3% and 81.5%, respectively. The total variance of the model was 90%. It was concluded that BMI can negatively affect HRQoL. On the other hand, PA and PF are able to increase HRQoL levels during the aging process.

ABSTRACT

The present study aimed to examine whether gait speed (GS), body balance (BB), and falls mediated the relationship between physical activity (PA) and health-related quality of life (HRQoL) in community-dwelling older adults. This is a cross-sectional study that included 305 men and 314 women (69.5 ± 5.6 years), residing in the Autonomous Region of Madeira, Portugal. HRQoL and PA were assessed using the SF-36 and Baecke Questionnaires, respectively. While BB was obtained by the Fullerton Advance Balance (FAB) scale, GS by the 50-foot (15 m) walk test, and the frequency of falls was obtained by self-report. According to the analyses, when GS and BB were placed concomitantly as mediators, the direct effect revealed by the model revealed a non-significant relationship between PA and falls. Thus, in the context of falls, GS and BB partially mediated the association between PA and HRQoL in approximately 29.7%, 56%, and 49.2%, respectively. The total HRQoL model explained a variance of 36.4%. The results can help to understand the role that GS, BB, and falls play in the relationship between PA and HRQoL of the vulnerable older adult population.

ABSTRACT

Lower extremity muscle strength (LEMS) and body balance (BB) are essential for older adults to maintain an upright posture and autonomously perform their basic activities of daily living. This study aimed to examine whether LEMS and BB mediate the relationship between physical activity (PA) and health-related quality of life (HRQoL) in a large sample of community-dwelling older adults. This is a cross-sectional study carried out with 802 individuals, 401 males and 401 females (69.8 ± 5.6 years), residents of the Autonomous Region of Madeira, Portugal. PA and HRQoL were assessed by the Baecke Questionnaire and e SF-36, respectively. LEMS was assessed by the Senior Fitness Test and BB by the Fullerton Advance Balance (FAB). The serial mediation pathway model pointed out that LEMS and BB partially mediated the association between PA and HRQoL in approximately 39.6% and 47%, respectively. The total variance in HRQoL explained by the entire model was 98%. Our findings may indicate the role that LEMS and BB play in the relationship between PA and HRQoL in the older population.

ABSTRACT

OBJECTIVE: To evaluate clinical practices and hospital resource organization during the early COVID-19 pandemic in Brazil. METHODS: This was a multicenter, cross-sectional survey. An electronic questionnaire was provided to emergency department and intensive care unit physicians attending COVID-19 patients. The survey comprised four domains: characteristics of the participants, clinical practices, COVID-19 treatment protocols and hospital resource organization. RESULTS: Between May and June 2020, 284 participants [median (interquartile ranges) age 39 (33 - 47) years, 56.3% men] responded to the survey; 33% were intensivists, and 9% were emergency medicine specialists. Half of the respondents worked in public hospitals. Noninvasive ventilation (89% versus 73%; p = 0.001) and highflow nasal cannula (49% versus 32%; p = 0.005) were reported to be more commonly available in private hospitals than in public hospitals. Mechanical ventilation was more commonly used in public hospitals than private hospitals (70% versus 50%; p = 0,024). In the Emergency Departments, positive endexpiratory pressure was most commonly adjusted according to SpO2, while in the intensive care units, positive end-expiratory pressure was adjusted according to the best lung compliance. In the Emergency Departments, 25% of the respondents did not know how to set positive end-expiratory pressure. Compared to private hospitals, public hospitals had a lower availability of protocols for personal protection equipment during tracheal intubation (82% versus 94%; p = 0.005), managing mechanical ventilation [64% versus 75%; p = 0.006] and weaning patients from mechanical ventilation [34% versus 54%; p = 0.002]. Finally, patients spent less time in the emergency department before being transferred to the intensive care unit in private hospitals than in public hospitals [2 (1 - 3) versus 5 (2 - 24) hours; p < 0.001]. CONCLUSION: This survey revealed significant heterogeneity in the organization of hospital resources, clinical practices and treatments among physicians during the early COVID-19 pandemic in Brazil.


OBJETIVO: Avaliar as práticas clínicas e a organização dos recursos hospitalares durante o início da pandemia da COVID-19 no Brasil. METÓDOS: Foi realizado um estudo transversal multicêntrico. Um questionário on-line foi disponibilizado a médicos dos serviços de emergência e das unidades de terapia intensiva que atendiam pacientes com COVID-19. O questionário contemplava quatro aspectos: perfil dos participantes, práticas clínicas, protocolos de tratamento da COVID-19 e organização dos recursos hospitalares. RESULTADOS: Entre maio e junho de 2020, 284 participantes (56,3% homens), com idade mediana de 39 (intervalo interquartil de 33 - 47), responderam ao questionário; 33% eram intensivistas e 9% eram especialistas em medicina de emergência. Metade dos respondentes trabalhava em hospitais públicos. Verificou-se que a ventilação não invasiva (89% versus 73%; p = 0,001) e a cânula nasal de alto fluxo (49% versus 32%; p = 0,005) encontravam-se mais frequentemente disponíveis em hospitais privados do que nos públicos. A ventilação mecânica foi mais frequentemente utilizada em hospitais públicos do que em privados (70% versus 50%; p = 0,024). Nos serviços de emergência, a pressão positiva expiratória final foi mais frequentemente ajustada de acordo com a saturação de oxigênio, enquanto nas unidades de terapia intensiva, a pressão positiva expiratória final foi ajustada de acordo com a melhor complacência pulmonar. Nos serviços de emergência, 25% dos respondentes não sabiam como ajustar a pressão positiva expiratória final. Comparativamente aos hospitais privados, os hospitais públicos tiveram menor disponibilidade de protocolos para Equipamentos de Proteção Individual durante a intubação traqueal (82% versus 94%; p = 0,005), o manejo da ventilação mecânica (64% versus 75%; p = 0,006) e o desmame dos pacientes da ventilação mecânica (34% versus 54%; p = 0,002). Finalmente, os pacientes passaram menos tempo no serviço de emergência antes de serem transferidos à unidade de terapia intensiva em hospitais privados do que em hospitais públicos (idade mediana de 2 (1 - 3) versus idade mediana de 5 (2 - 24) horas; p < 0,001). CONCLUSÃO: Este estudo revelou heterogeneidade considerável entre os médicos em termos de organização dos recursos hospitalares, práticas clínicas e tratamentos durante o início da pandemia da COVID-19 no Brasil.

ABSTRACT

INTRODUCTION: Small-bowel involvement in patients with ovarian cancer has been strongly correlated with the possibility of cytoreduction and thus with survival. The main objective of this study was to evaluate the prognostic significance of small-bowel involvement in patients undergoing optimal-complete interval cytoreductive surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC). METHODS: We included a series of patients diagnosed with stage IIIC-IVA (pleural effusion) high-grade serous epithelial ovarian cancer and in whom CRS + HIPEC was indicated after neoadjuvant systemic chemotherapy (NACT). The study period extended from January 2008 to January 2020, with a minimum follow-up of 12 months from the inclusion of the last patient. A multivariate analysis using Cox regression allowed us to identify the variables that were independently related to disease-free survival. RESULTS: A total of 144 patients were selected, 13 (9%) of whom were excluded from the analysis, because their disease was considered unresectable. The study included a series of 131 patients with a median age of 62 years (34-79 years) and a median Peritoneal Cancer Index (PCI) calculated during surgery of 9 (1-35). The median PCI of bowel areas 9-12 (SB-PCI) was 3 (1-10). Performance of a CC-1 cytoreduction (HR: 1.93, 95% CI: 1.02-3.64, p = 0.042) and SB-PCI greater than 3 (HR: 2.25, 95%CI: 1.13-4.48, p = 0.21) were independent factors associated with shorter disease-free survival. CONCLUSION: Small-bowel involvement, even in patients with a macroscopically complete resection, showed a correlation with worse prognostic outcomes and could be considered as a variable in the postoperative management of these patients.

ABSTRACT

RESUMO Objetivo: Avaliar as práticas clínicas e a organização dos recursos hospitalares durante o início da pandemia da COVID-19 no Brasil. Metódos: Foi realizado um estudo transversal multicêntrico. Um questionário on-line foi disponibilizado a médicos dos serviços de emergência e das unidades de terapia intensiva que atendiam pacientes com COVID-19. O questionário contemplava quatro aspectos: perfil dos participantes, práticas clínicas, protocolos de tratamento da COVID-19 e organização dos recursos hospitalares. Resultados: Entre maio e junho de 2020, 284 participantes (56,3% homens), com idade mediana de 39 (intervalo interquartil de 33 - 47), responderam ao questionário; 33% eram intensivistas e 9% eram especialistas em medicina de emergência. Metade dos respondentes trabalhava em hospitais públicos. Verificou-se que a ventilação não invasiva (89% versus 73%; p = 0,001) e a cânula nasal de alto fluxo (49% versus 32%; p = 0,005) encontravam-se mais frequentemente disponíveis em hospitais privados do que nos públicos. A ventilação mecânica foi mais frequentemente utilizada em hospitais públicos do que em privados (70% versus 50%; p = 0,024). Nos serviços de emergência, a pressão positiva expiratória final foi mais frequentemente ajustada de acordo com a saturação de oxigênio, enquanto nas unidades de terapia intensiva, a pressão positiva expiratória final foi ajustada de acordo com a melhor complacência pulmonar. Nos serviços de emergência, 25% dos respondentes não sabiam como ajustar a pressão positiva expiratória final. Comparativamente aos hospitais privados, os hospitais públicos tiveram menor disponibilidade de protocolos para Equipamentos de Proteção Individual durante a intubação traqueal (82% versus 94%; p = 0,005), o manejo da ventilação mecânica (64% versus 75%; p = 0,006) e o desmame dos pacientes da ventilação mecânica (34% versus 54%; p = 0,002). Finalmente, os pacientes passaram menos tempo no serviço de emergência antes de serem transferidos à unidade de terapia intensiva em hospitais privados do que em hospitais públicos (idade mediana de 2 (1 - 3) versus idade mediana de 5 (2 - 24) horas; p < 0,001). Conclusão: Este estudo revelou heterogeneidade considerável entre os médicos em termos de organização dos recursos hospitalares, práticas clínicas e tratamentos durante o início da pandemia da COVID-19 no Brasil.


ABSTRACT Objective: To evaluate clinical practices and hospital resource organization during the early COVID-19 pandemic in Brazil. Methods: This was a multicenter, cross-sectional survey. An electronic questionnaire was provided to emergency department and intensive care unit physicians attending COVID-19 patients. The survey comprised four domains: characteristics of the participants, clinical practices, COVID-19 treatment protocols and hospital resource organization. Results: Between May and June 2020, 284 participants [median (interquartile ranges) age 39 (33 - 47) years, 56.3% men] responded to the survey; 33% were intensivists, and 9% were emergency medicine specialists. Half of the respondents worked in public hospitals. Noninvasive ventilation (89% versus 73%; p = 0.001) and highflow nasal cannula (49% versus 32%; p = 0.005) were reported to be more commonly available in private hospitals than in public hospitals. Mechanical ventilation was more commonly used in public hospitals than private hospitals (70% versus 50%; p = 0,024). In the Emergency Departments, positive endexpiratory pressure was most commonly adjusted according to SpO2, while in the intensive care units, positive end-expiratory pressure was adjusted according to the best lung compliance. In the Emergency Departments, 25% of the respondents did not know how to set positive end-expiratory pressure. Compared to private hospitals, public hospitals had a lower availability of protocols for personal protection equipment during tracheal intubation (82% versus 94%; p = 0.005), managing mechanical ventilation [64% versus 75%; p = 0.006] and weaning patients from mechanical ventilation [34% versus 54%; p = 0.002]. Finally, patients spent less time in the emergency department before being transferred to the intensive care unit in private hospitals than in public hospitals [2 (1 - 3) versus 5 (2 - 24) hours; p < 0.001]. Conclusion: This survey revealed significant heterogeneity in the organization of hospital resources, clinical practices and treatments among physicians during the early COVID-19 pandemic in Brazil.

ABSTRACT

INTRODUCTION: Malaria cases in Brazil are concentrated in the Amazon region. In the state of Pará, malaria is considered an endemic disease, and the population has different levels of exposure, which contributes to different types of occurrence in the municipalities. METHODOLOGY: A descriptive, cross-sectional, and ecological study was conducted using data from the Malaria Epidemiological Surveillance System of the municipalities of Cametá and Tucuruí, PA, Brazil, from 2014 to 2018; the Brazilian Institute of Geography and Statistics; and the National Registry of Health Institutions of the Ministry of Health. Statistical and spatial analyses of epidemiological, laboratory and public health service coverage variables were performed using the Bioestat 5.0 and ArcGis 10.5 software. RESULTS: 11,381 Malaria cases were reported in the two municipalities. The highest percentage of case notifications was reported in brown-skinned men aged from 19 and 59 years, and who had primary education levels. The predominant occupations were farming and livestock in Cametá and domestic activity in Tucuruí. The most common diagnostic examination used was a thick blood smear, and Plasmodium vivax was the species most often encountered. The percentage of primary care coverage increased during the study period. The spatial distribution of the disease was not homogeneous, and there were clusters of cases with different densities in Cametá and Tucuruí. CONCLUSIONS: Malaria is a public health problem in the municipalities of Cametá and Tucuruí, because of its transmission dynamics and variable spatial distribution as well as the coexistence of factors that favor the exposure of resident populations to epidemiological situations, thus reflecting health inequities.

ABSTRACT

Hemodialysis central venous catheter (CVC) insertion can be complicated in patients with anomalous vessel anatomy. In such cases detailed knowledge of thoracic vessel anatomy is necessary to identify the exact location of the catheter. Central venous placement under ultrasound control has significantly reduced the complications associated with blind puncture and allows an appropriate puncture of the desired vessel, but the CVC can still get misplaced if it follows an anomalous route. Herein, we report a case of dialysis catheter placed into a left sided superior vena cava, only diagnosed after CT scan study.
