Prediction of acute neurovascular syndromes with prehospital clinical features witnessed by bystanders.

BACKGROUND: The prompt recognition of an acute neurovascular syndrome by the patient or a bystander witnessing the event can directly influence outcome. We aimed to study the predictive value of the medical history and clinical features recognized by the patients' bystanders to preclassify acute stroke syndromes in prehospital settings. METHODS: We analyzed 369 patients: 209 (56.6%) with acute ischemic stroke (AIS), 107 (29.0%) with intracerebral hemorrhage (ICH), and 53 (14.4%) with subarachnoid hemorrhage (SAH). All patients had neuroimaging as diagnostic gold standard. We constructed clinical prediction rules (CPRs) with features recognized by the bystanders witnessing the stroke onset to classify the acute neurovascular syndromes before final arrival to the emergency room (ER). RESULTS: In all, 83.2% cases were referred from other centers, and only 16.8% (17.2% in AIS, 15% in ICH, and 18.9% in SAH) had direct ER arrival. The time to first assessment in ≤ 3 h occurred in 72.4% (73.7%, 73.8%, and 64.2%, respectively), and final ER arrival in ≤ 3 h occurred in 26.8% (32.1%, 15.9%, and 28.3%, respectively). Clinical features referred by witnesses had low positive predictive values (PPVs) for stroke type prediction. Language or speech disorder + focal motor deficit showed 63.3% PPV, and 77.0% negative predictive value (NPV) for predicting AIS. Focal motor deficit + history of hypertension had 35.9% PPV and 78.8% NPV for ICH. Headache alone had 27.9% PPV and 95.3% NPV for SAH. In multivariate analyses, seizures, focal motor deficit, and hypertension increased the probability of a time to first assessment in ≤ 3 h, while obesity was inversely associated. Final ER arrival was determined by age and a direct ER arrival without previous referrals. CONCLUSION: CPRs constructed with the witnesses' narrative had only adequate NPVs in the prehospital classification of acute neurovascular syndromes, before neuroimaging confirmation.

Probabilistic multi-pathway human health risk assessment due to heavy metal(loid)s in a traditional gold mining area in Ecuador.

Mining operations are important causes of environmental pollution in developing countries where mining waste management is not adequate. Consequently, heavy metal(loid)s are easily released into the environment, being a potential risk to human health. This study carries out a Bayesian probabilistic human health risk assessment, related to multi-pathway exposure to heavy metal(loid)s in a gold mining area in Southern Ecuador. Concentrations of As, Cd, Cr, Cu, Ni, Pb, and Zn in tap water, surface water, and soil samples, were analyzed to assess the potential adverse human health effects based on the Hazard Index (HI) and Total cancer risk (TCR). Adults and children residents were surveyed to adjust their exposure parameters to the site-specific conditions. Exposure to heavy metal(loid)s resulted in unacceptable risk levels for human health in the two age groups, both carcinogenic (TCR > 1 × 10-5) and non-carcinogenic (HI > 1) through ingestion of tap water and incidental ingestion of surface water. Sensitivity analysis showed that As concentration in waters and exposure frequency were the main contributors to risk outcome. Exposure to soil via accidental ingestion and dermal contact was below the safety limit, not posing a risk to human health. These findings can provide a baseline for the environmental management of the mining area and indicate the need for further research on As pollution in water and its implications on the health of the inhabitants of mining communities.

Ecological and probabilistic human health risk assessment of heavy metal(loid)s in river sediments affected by mining activities in Ecuador.

Gold mining is a significant source of metal(loid)s released into the environment. It is an issue of concern due to the potential adverse health effects associated with exposure to toxic elements. This study aimed to assess the ecological and human health risk caused by heavy metal(loid)s exposure in river sediments in Ponce Enríquez, one of the most important mining sites in Ecuador. Concentrations of As, Cd, Cu, Pb, and Zn were evaluated in 172 sediment samples to determine the Potential ecological risk (RI) and the carcinogenic (CR) and non-carcinogenic risk (HQ). The human exposure to polluted sediments during recreational activities was computed using Bayesian probabilistic models. Residents were randomly surveyed to adjust the risk models to the specific population data. More than 68% of the sampling stations pose a severe As and Cd ecological risk index ([Formula: see text] > 320). Likewise, residents exposed to river sediments showed a non-acceptable carcinogenic risk by incidental ingestion, being As the primary contributor to overall cancer in both children and adults receptors. Moreover, non-carcinogenic risk through the incidental ingestion of sediments was above the safe limit for children. This is the first study conducted in a mining region in Ecuador that reveals the severe levels of ecological and human health risk to which the population is exposed. These results can be applied as a baseline to develop public health strategies to monitor and reduce the health hazards of the residents of mining communities.

OBJECTIVE: To describe the process of implanting the surgical safety checklist in a catheterization laboratory (CL). METHOD: Descriptive case report study about the safety strategies developed in the last six years in a university hospital in the southern region of Brazil. RESULTS: The six international patient safety goals (IPSG) were incorporated into the care practice in accordance with the hospital's Joint Comission International (JCI) accreditation program, through a continuous process of educational nature. The checklist was adapted considering the characteristics of the unit and the procedures performed. CONCLUSION: The implementation of the checklist provided the promotion of patient safety, greater staff integration, advances in communication among professionals and the recording of in-room care information.

Two HEmostasis Methods After TransradIal Catheterization: THEMATIC - protocol for a randomized clinical trial.

OBJECTIVE: Randomized clinical trial protocol to evaluate the incidence of radial artery occlusion with two different arterial compression devices after transradial procedures. METHODS: Barbeau's test will be performed in adults scheduled to undergo transradial interventional procedures. Those with A, B, or C plethysmographic patterns will be selected. At the end of the procedure, patients will be randomly assigned (1:1) to receive patent haemostasis with TR Band™ device or conventional haemostasis with an elastic adhesive bandage. The primary outcome is the incidence of radial artery occlusion. Secondary outcomes are Barbeau's test curve change, additional time to achieve haemostasis, incidence of bleeding at the puncture site, pain severity, development of arteriovenous fistula, radial pseudo aneurysm, any access-site complication requiring vascular surgery intervention and costs between the two devices. DISCUSSION: The results of this trial should provide valuable additional information on the best approach for haemostasis after transradial percutaneous cardiovascular interventions.

Changes in quality of life associated with surgical risk in elderly patients undergoing cardiac surgery.

The study aims to verify quality of life of elderly patients submitted to cardiac surgery, and correlating surgical risk to health-related quality of life instrument domains. Prospective cohort study, performed at a cardiology hospital. It included elderly patients who had undergone elective cardiac surgery. Pre- and postoperative quality of life was evaluated by applying the World Health Organization Quality of Life-Old (WHOQOL-OLD) scale and the Short-Form Health Survey (SF-36) questionnaire. Surgical risk was stratified using the European System for Cardiac Operative Risk Evaluation (EuroSCORE). Fifty-four patients, mostly men (64.8%), were included, with a mean age of 69.3 ± 5.7 years. The eight domains of the SF-36 questionnaire, and the four facets presented for the WHOQOL-OLD scale showed improved quality of life 6 months after surgery (P < 0.001). No difference was found in the association of EuroSCORE with the domains of the health-related quality of life instruments. The data showed improved quality of life of elderly people submitted to cardiac surgery, unrelated to surgical risk.

Evaluation of Factors Influencing Handgrip Strength Asymmetry in Older Peruvian Adults.

BACKGROUND: Sarcopenia is a musculoskeletal disease involving the reduction of muscle mass, strength, and performance. Handgrip strength (HGS) measurements included in frailty assessments are great biomarkers of aging and are related to functional deficits. We assessed the association between potential influencing factors and HGS asymmetry in older Peruvian adults. METHODS: We used a database of the Peruvian Naval Medical Center "Cirujano Santiago Távara" located in Callao, Peru. All the patients included were ≥60 years old and had an HGS measurement in the dominant and non-dominant hand. RESULTS: From a total of 1,468 patients, 74.66% had HGS asymmetry. After adjustment, calf circumference weakness (adjusted prevalence ratio [aPR]=1.08; 95% confidence interval [CI], 1.01-1.15), falls risk (aPR = 1.08; 95% CI, 1.02-1.16), and an altered Lawton index (aPR=0.92; 95% CI, 0.84-0.99) were associated with HGS asymmetry. CONCLUSION: Our findings suggest that HGS asymmetry should be measured along with other geriatric assessments used to evaluate health outcomes in the elderly to enhance health promotion and prevention aimed at preserving muscle strength to curb functional limitations in the elderly.

Role of cytokines, chemokines, C3a, and mannose-binding lectin in the evolution of the chikungunya infection.

The pathogenesis of the severity of chikungunya infection is not yet fully understood. OBJECTIVE: To assess the role of the cytokines/chemokines and system of complement in the evolution of chikungunya infection. METHODS: In both acute and chronic phases, we measured the serum levels of 12 cytokines/chemokines and two complement mediators: mannose-binding lectin (MBL) and C3a, in 83 patients with chikungunya infection and ten healthy controls. RESULTS: During the acute phase, 75.9% of the patients developed musculoskeletal disorders, and in 37.7% of them, these disorders persisted until the chronic phase. In general, patients had higher levels of cytokines than healthy controls, with significant differences for IFN-γ, IL-6, IL-8, IL-10, and MIP-1. Most cytokines exhibited a downward trend during the chronic phase. However, only IL-10, and MIP-1 levels were significantly lower in the chronic phase. Additionally, these levels never decreased to concentrations found in healthy controls. Moreover, MBL levels were significantly higher in the acute phase compared with the chronic phase. C3a levels were significantly higher in patients with musculoskeletal disorder compared with patients without it, in both acute-phase 118.2 (66.5-252.9), and chronic phase 68.5 (64.4-71.3), P < 0.001. Interestingly, C3a levels were significantly higher when patients had a severe disease version. Besides, in the acute phase, C3a levels were higher in patients that suffer arthritis as opposed to when they suffer arthralgia, 194.3 (69.5-282.2), and 70.9 (62.4-198.8), P = 0.013, respectively. CONCLUSIONS: Our results showed an immunological response that persisted until the chronic phase and the role of the complement system in the severity of the disease.

Student-Authored Scientist Spotlights: Investigating the Impacts of Engaging Undergraduates as Developers of Inclusive Curriculum through a Service-Learning Course.

Scientist Spotlights-curricular materials that employ the personal and professional stories of scientists from diverse backgrounds-have previously been shown to positively influence undergraduate students' relatability to and perceptions of scientists. We hypothesized that engaging students in authoring Scientist Spotlights might produce curricular materials of similar impact, as well as provide a mechanism for student involvement as partners in science education reform. To test this idea and investigate the impact of student-authored Scientist Spotlights, we developed a service-learning course in which teams of biology students partnered with an instructor to develop and implement Scientist Spotlights in a biology course. Results revealed that exposure to three or four student-authored Scientist Spotlights significantly shifted peers' perceptions of scientists in all partner courses. Interestingly, student-authored Scientist Spotlights shifted peers' relatability to scientists similarly among both white students and students of color. Further, student authors themselves showed increases in their relatability to scientists. Finally, a department-wide survey demonstrated significant differences in students' perceptions of scientist representation between courses with and without student-authored Spotlights. Results suggest that engaging students as authors of inclusive curricular materials and partners in reform is a promising approach to promoting inclusion and addressing representation in science.

Importance of clinical and laboratory characteristics in the diagnosis of dengue and chikungunya co-infection: Probable case report / Importancia de las características clínicas y de laboratorio en el diagnóstico de las infecciones concomitantes por dengue y chikungunya: reporte de un caso probable.

We report the case of a 38-year-old woman who initially consulted for an undifferentiated fever. Although her clinical condition evolved with signs and symptoms compatible with dengue with alarm signs and that the anti-dengue IgM detection in a single sample indicated it was a probable case that could have happened during the previous three months, the patient kept consulting due to little improvement. On the tenth day after the onset of symptoms, she presented with painful polyarticular symmetric edema, as well as hyperpigmented lesions in the nasolabial fold. Chikungunya diagnosis was confirmed by the presence of IgM antibodies. In endemic countries for dengue and chikungunya, the possibility of co-infection exists, but it may go unnoticed. On the other hand, the co-infection may worsen the clinical course of these diseases. Therefore, physicians should evaluate the clinical and laboratory characteristics of both infections to be able to diagnose the coinfection for adequate management and to minimize complications.

Se presenta el caso de una mujer de 38 años que consultó inicialmente por fiebre indiferenciada. A pesar de que el cuadro clínico evolucionó con manifestaciones clínicas de dengue con signos de alarma y de que la detección de IgM antidengue en una sola muestra indicaba que se trataba de un caso probable que había podido ocurrir durante los tres meses anteriores, la paciente consultó de forma reiterada, pues no presentaba una mejoría significativa. En el décimo día del inicio de los síntomas, se observó edema simétrico en múltiples articulaciones acompañado de dolor, así como lesiones hiperpigmentadas en el surco nasogeniano. Se confirmó el diagnóstico de chikungunya por la presencia de anticuerpos IgM. Aunque puede pasar desapercibida, en los países endémicos para dengue y chikungunya existe la posibilidad de la infección concomitante, la cual puede agravar la evolución clínica de cada una de estas enfermedades. Por ello, es necesario que el médico considere las características clínicas y de laboratorio de ambas enfermedades para diagnosticar su presencia simultánea, garantizar un manejo adecuado y minimizar las complicaciones.

[The approach to gender violence from the perspective of communities in northern Córdoba Province, Argentina]. / El abordaje de la violencia de género desde la perspectiva de las comunidades del norte cordobés, Argentina.

Gender violence is a human rights violation and a serious public health problem that should be addressed with an inter-sector and interdisciplinary focus. Collaboration and coordination between sectors, including the health sector, is essential for guaranteeing such approach. The study aimed to learn which actors address gender violence in the communities and to study the communities' opinions concerning the public health system's role in (and approach to) this problem. A qualitative action-research project was conducted with local community self-diagnosis workshops, using various qualitative techniques and thematic analysis. The results pointed to various local actors that address the problem and showed that primary healthcare plays a relevant role, due mainly to its proximity to the population and interdisciplinary approach. The obstacles identified by the communities for the health system approach mainly involved the biomedical model of care, decentralization, and lack of resources, training, and integrated policies. In conclusion, the workshops facilitated the development of collective knowledge on the local reality, underlining the role of primary healthcare and the need to link action and approaches between sectors and communities.

Subsample analysis of the Vascular Complications Risk Score at two public referral centers for interventional cardiology.

OBJECTIVE: Evaluate the performance of the Vascular Complications Risk Score in two public referral centers for interventional cardiology. METHOD: Subsample analysis of the Vascular Complications Risk Score, which was developed and validated in the catheterization laboratories of three cardiology referral centers (two public, one private) with a cutoff of <3 for no risk of developing vascular complications and ≥3 for risk. In this new analysis, we excluded data from the private facility, and only included participants from the original (validation) cohort of the two public hospitals. RESULTS: Among the 629 patients studied, 11.8% had vascular complications; of these, 1.8% were major and 10% minor. Among the patients with a score <3, 310 (94.5%) presented no vascular complications; of those with a score ≥3, 50 (17%) developed complications. Of those who developed vascular complications, 18 scored <3; two of these had major complications. CONCLUSION: This subanalysis confirms the ability of the Vascular Complications Risk core to predict low risk of vascular complications in patients with a score < 3.

Antifungal Effects of Silver Phytonanoparticles from Yucca shilerifera Against Strawberry Soil-Borne Pathogens: Fusarium solani and Macrophomina phaseolina.

In the present study, the characterization and properties of silver nanoparticles from Yucca shilerifera leaf extract (AgNPs) were investigated using UV-visible spectroscopic techniques, zeta potential, and dynamic light scattering. The UV-visible spectroscopic analysis showed the absorbance peaked at 460 nm, which indicated the synthesis of silver nanoparticles. The experimental results showed silver nanoparticles had Z-average diameter of 729 nm with lower stability (195.1 mV). Additionally, our dates revealed that AgNPs showed broad spectrum antagonism (p ≤ .05) against Fusarium solani (83.05%) and Macrophomina phaseolina (67.05%) when compared to the control after nine days of incubation. Finally, AgNPs from leaf extracts of Y. shilerifera may be used as an agent of biocontrol of microorganism of importance. However, further studies will be needed to fully understand the agronanotechnological potentialities of AgNPs from Yucca schidigera.

Comparative study of risk factors related to cardiovascular disease in children from Bogotá, Colombia and Toluca, Mexico.

INTRODUCTION: Currently, cardiovascular risk factors have not been studied so extensively in young people. OBJECTIVE: To compare the cardiovascular risk factor between Colombian and Mexican children. PATIENTS AND METHODS: This was a transversal, descriptive, comparative and clinical study. 30 children of primary school aged 6-12 from Bogotá, Colombia were matched by age with a sample of 30 children from Toluca, Mexico. Cardiovascular risk factors measured were Body Mass Index (BMI), serum lipid profile, glucose and homocystein (Hcy). Besides we applied the validated surveys formats for food (dietary history), physical activity (International Physical Activity Questionnaire, IPAQ), alcohol consumption and smoking. RESULTS: BMI was higher in Mexican children than in Colombian (20.43±3.35 vs 16.92±3.46) (p≤0.001). Among Mexican children, 20% (6) of them had blood glucose concentration greater than 100 mg/dl, 6.6% (2) had triglycerides greater than 200 mg/dl, 36.6% (11) had cholesterol levels greater than 170 mg/dl, 16% (53.3) had HDL lower than the recommended limits, and 60% (18) had LDL above the normal limit. For the Colombian population these percentages were of 0, 3.3, 46.6, 13.33 and 53.3 respectively. DISCUSSION: Mexican children had a stronger correlation between BMI and atherogenic indices and less physical activity than Colombian. Of the 30 Mexican children enrolled in the study only 13% had none of the cardiovascular risk factors, while in the Colombian this percentage was of 33. CONCLUSION: Latin American children are not metabolically homogeneous, Mexican children are at high risk of cardiovascular disease.

CONCLUSION The implementation of the checklist provided the promotion of patient safety, greater staff integration, advances in communication among professionals and the recording of in-room care information.

Two HEmostasis Methods After TransradIal Catheterization: THEMATIC - protocol for a randomized clinical trial / Dos métodos de hemostasia luego de un cateterismo transradial: THEMATIC - protocolo de ensayo clínico aleatorizado / Dois métodos de hemostasia após cateterismo transradial: THEMATIC - protocolo de ensaio clínico randomizado

Abstract OBJECTIVE Randomized clinical trial protocol to evaluate the incidence of radial artery occlusion with two different arterial compression devices after transradial procedures. METHODS Barbeau's test will be performed in adults scheduled to undergo transradial interventional procedures. Those with A, B, or C plethysmographic patterns will be selected. At the end of the procedure, patients will be randomly assigned (1:1) to receive patent haemostasis with TR Band™ device or conventional haemostasis with an elastic adhesive bandage. The primary outcome is the incidence of radial artery occlusion. Secondary outcomes are Barbeau's test curve change, additional time to achieve haemostasis, incidence of bleeding at the puncture site, pain severity, development of arteriovenous fistula, radial pseudo aneurysm, any access-site complication requiring vascular surgery intervention and costs between the two devices. DISCUSSION The results of this trial should provide valuable additional information on the best approach for haemostasis after transradial percutaneous cardiovascular interventions.

Resumen OBJETIVO Protocolo de ensayo clínico randomizado para evaluar la incidencia de oclusión de la arteria radial con dos dispositivos de compresión arterial después de pasar por procedimientos transradiales. MÉTODO Se realizará el test de Barbeau en adultos que están esperando una intervención transradial. Se seleccionarán aquellos con padrones pletismográficos A, B o C. Al final del procedimiento, se dividirán a los pacientes de forma aleatoria (1:1) para recibir la hemostasia patente con dispositivo TR Band™ o hemostasia convencional con vendaje elástico adhesivo. El resultado primario es la incidencia de oclusión de la arteria radial. Los resultados secundarios son la alteración de la curva del test de Barbeau, tiempo adicional para alcanzar la hemostasia, incidencia de sangrado en el local de la punción, intensidad del dolor, desarrollo de una fístula arteriovenosa, pseudoaneurisma, cualquier complicación en el lugar de acceso que necesite intervención quirúrgica vascular y costos entre ambos dispositivos. DISCUSIÓN Los resultados de este estudio deben proporcionar informaciones adicionales valiosas sobre un mejor enfoque para la hemostasia luego de intervenciones cardiovasculares percutáneas transradiales.

Resumo OBJETIVO Protocolo de ensaio clínico randomizado para avaliar a incidência de oclusão da artéria radial com dois dispositivos diferentes de compressão arterial após procedimentos transradiais. MÉTODOS O teste de Barbeau será realizado em adultos que serão submetidos a procedimentos de intervenção transradial previamente agendados. Aqueles com padrões pletismográficos A, B ou C serão selecionados. No final do procedimento, os pacientes serão distribuídos aleatoriamente (1:1) para receber hemostasia patente com dispositivo TR Band™ ou hemostasia convencional com bandagem elástica adesiva. O desfecho primário é a incidência da oclusão da artéria radial. Os desfechos secundários são alteração da curva do teste de Barbeau, tempo adicional para atingir a hemostasia, incidência de sangramento no local da punção, intensidade da dor, desenvolvimento de fístula arteriovenosa, pseudoaneurisma, qualquer complicação no local de acesso que necessite intervenção cirúrgica vascular e custos entre os dois dispositivos. DISCUSSÃO: Os resultados deste estudo devem fornecer informações adicionais valiosas sobre a melhor abordagem para a hemostasia após intervenções cardiovasculares percutâneas transradiais.
