RESUMEN El bienestar de los animales terrestres describe las expectativas de la sociedad sobre las condiciones que los animales deberían experimentar cuando están bajo el control humano. Estos principios incluyen que los animales deben estar libres de dolor, lesiones y enfermedades. La inflamación es el mecanismo de defensa de un huésped contra una infección bacteriana o viral, o una lesión física o química al huésped. Los metabolitos secundarios de las plantas son una alternativa eficaz para el tratamiento de enfermedades inflamatorias. El propósito de esta investigación fue evaluar la capacidad antiinflamatoria de un extracto hidroalcohólico de hojas de Salix babylonica (HESB) empleando el modelo de edema auricular inducido por TPA en ratones. El HESB mostró una buena actividad antiinflamatoria sin diferencia estadística significativa con el fármaco de referencia, indometacina. Por este motivo, se realizó una bipartición de HESB, obteniendo una fracción acuosa (AFSB) con actividad farmacológica leve (30.64 ± 3.03 %) y una fracción orgánica (EAFSB) que mostró el mejor efecto antiinflamatorio (67.08 ± 7.15 %). Anteriormente, identificamos los flavonoides antiinflamatorios luteolina y luteolosido como los componentes principales de EAFSB, por lo que el efecto antiinflamatorio de Salix babylonica puede ser atribuido a estos compuestos. Además, el análisis histopatológico mostró que las orejas de los ratones tratados con Salix babylonica suprimieron la infiltración de neutrófilos en el sitio de inflamación. Estos resultados apoyan el uso etnomédico de esta planta y evidencian el posible uso de Salix babylonica en el tratamiento del proceso inflamatorio en animales.

ABSTRACT The wellbeing of terrestrial animals describes society’s expectations for the conditions animals should experience when under human control. These principles include that animals must be free from pain, injury and disease. Inflammation is a host’s defensive mechanism against bacterial or viral infection and physical or chemical stimulus to the host. Metabolites from plants are an efficient alternative for treatment of inflammatory diseases. The purpose of this research was to evaluate the anti-inflammatory capacity of a hydro-alcoholic extract from Salix babylonica leaves (HESB) employing the auricular edema induced by the TPA model in mice. The HESB showed good anti-inflammatory activity without significant difference from the reference drug, indomethacin. For this reason, a bipartition of HESB was conducted, obtaining an aqueous fraction (AFSB) with slight activity (30.64 ± 3.03 %) and an organic fraction (EAFSB), which showed the best anti-inflammatory effect (67.08 ± 7.15 %). Previously, we identified anti-inflammatory flavonoids luteolin and luteoloside as the major components of EAFSB. In addition, histopathological analysis showed that mouse ears treated with Salix babylonica suppressed neutrophil infiltration into the inflammation site. These results support the ethno-medical use of this plant and evidenced that Salix babylonica’s applicability and value as an anti-inflammatory treatment for animals.

Abstract Background The efficacy of intravenous thrombolysis (IVT) is time-dependent. Objective To compare the door-to-needle (DTN) time of stroke neurologists (SNs) versus non-stroke neurologists (NSNs) and emergency room physicians (EPs). Additionally, we aimed to determine elements associated with DTN ≤ 20 minutes. Methods Prospective study of patients with IVT treated at Clínica Alemana between June 2016 and September 2021. Results A total of 301 patients underwent treatment for IVT. The mean DTN time was 43.3 ± 23.6 minutes. One hundred seventy-three (57.4%) patients were evaluated by SNs, 122 (40.5%) by NSNs, and 6 (2.1%) by EPs. The mean DTN times were 40.8 ± 23, 46 ± 24.7, and 58 ± 22.5 minutes, respectively. Door-to-needle time ≤ 20 minutes occurred more frequently when patients were treated by SNs compared to NSNs and EPs: 15%, 4%, and 0%, respectively (odds ratio [OR]: 4.3, 95% confidence interval [95%CI]: 1.66–11.5, p = 0.004). In univariate analysis DTN time ≤ 20 minutes was associated with treatment by a SN (p = 0.002), coronavirus disease 2019 pandemic period (p = 0.21), time to emergency room (ER) (p = 0.21), presence of diabetes (p = 0.142), hypercholesterolemia (p = 0.007), atrial fibrillation (p < 0.09), score on the National Institutes of Health Stroke Scale (NIHSS) (p = 0.001), lower systolic (p = 0.143) and diastolic (p = 0.21) blood pressures, the Alberta Stroke Program Early CT Score (ASPECTS; p = 0.09), vessel occlusion (p = 0.05), use of tenecteplase (p = 0.18), thrombectomy (p = 0.13), and years of experience of the physician (p < 0.001). After multivariate analysis, being treated by a SN (OR: 3.95; 95%CI: 1.44–10.8; p = 0.007), NIHSS (OR: 1.07; 95%CI: 1.02–1.12; p < 0.002) and lower systolic blood pressure (OR: 0.98; 95%CI: 0.96–0.99; p < 0.003) remained significant. Conclusions Treatment by a SN resulted in a higher probability of treating the patient in a DTN time within 20 minutes.

Resumen Antecedentes La respuesta a la trombólisis intravenosa (TIV) es dependiente del tiempo. Objetivo Comparar los tiempo puerta-aguja (TPAs) de neurólogos vasculares (NVs) contra los de neurólogos no vasculares (NNVs) y médicos emergencistas (MEs), y determinar los elementos asociados a un PTA ≤ 20 minutos. Métodos Análisis observacional prospectivo de pacientes con TIV tratados en Clínica Alemana entre junio de 2016 y septiembre de 2021. Resultados En total, 301 pacientes con TIV fueron tratados. El TPA promedio fue de 43,3 ± 23,6 minutos. Un total de 173 (57,4%) pacientes fueron evaluados por NVs, 122 (40,5%), por NNVs, y 6 (2,1%), por MEs; los TPAs promedios fueron de 40,8 ± 23; 46 ± 24,7 y 58 ± 22,5 minutos, respectivamente. Los TPAs ≤ 20 minutos fueron más frecuentes en pacientes tratados por NVs versus NNVs y MEs: 15%, 4% y 0%, respectivamente (odds ratio [OR]: 4,3; intervalo de confianza del 95% [IC95%]: 1,66–11,5; p = 0,004). El análisis univariado demostró que TPA ≤ 20 minutos se asoció con: tratamiento por NVs (p = 0,002), periodo de la pandemia de enfermedad por coronavirus 2019 (COVID-19; p = 0,21), tiempo a urgencia (p = 0,21), diabetes (p = 0,142), hipercolesterolemia (p = 0,007), fibrilación auricular (p < 0,09), puntaje en la National Institutes of Health Stroke Scale [NIHSS] (p = 0,001), presión arterial sistólica (p = 0,143) y diastólica menores (p = 0,21), Alberta Stroke Program Early CT Score (ASPECTS ; p = 0,09), oclusión de vasos cerebrales (p =0,05), uso de tecneteplase (p = 0,18), trombectomía (p = 0,13) y años de experiencia del médico (p < 0,001). El análisis multivariado demostró que ser tratado por NVs (OR: 3,95; IC95%: 1,44–10,8; p = 0,007), el puntaje en la NIHSS (OR: 1,07; IC95%: 1,02–1,12; p < 0,002) y la presión arterial sistólica (OR: 0,98; IC95%: 0,96–0,99; p < 0,003) se asociaron a TPA ≤ 20 minutos. Conclusões El tratamiento por NVs resultó en un TPA menor y en una mayor probabilidad de tratamiento ≤ 20 minutos.

Abstract Dermatitis is defined as a set of inflammatory diseases that affect the skin, with varied causes. Among the different types of dermatitis, contact dermatitis is the most prevalent. Although the current therapy is often effective, it is associated with adverse effects and the possibility of drug tolerance. N-Methyl-(2S, 4R)-trans-4-hydroxy-L-proline is a L-proline amino acid derivative found in the leaves of Sideroxylon obtusifolium, a species traditionally used to treat inflammatory diseases. The aim of this study was to investigate the topical anti-inflammatory effect of N-methyl-(2S, 4R)-trans-4-hydroxy-L-proline (NMP) in 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced irritant contact dermatitis in mice. Topically administered NMP, at doses of 0.03 − 0.50 mg/ear, reduced TPA-induced ear edema and neutrophil migration, as evidenced by low tissue myeloperoxidase activity and verified by histological examination. In addition, NMP (0.06 mg/ear) reduced tissue levels of pro-inflammatory cytokines (TNF-α, IL-6, IL-1β, INF-γ and MCP-1) and of the anti-inflammatory cytokine IL-10, and reduced gene expression of TNF-α, IL-6 and IL-1β increased by TPA. The data suggest that N-methyl-(2S, 4R)-trans-4-hydroxy-L-proline acts as a topical anti-inflammatory agent that decreases the expression of inflammatory cytokines, making it useful for the treatment of skin inflammation. Further investigations are necessary for its development as a therapeutic agent.

ABSTRACT Purpose to identify a set of requirements for the development of an auditory-perceptual training simulator (APT) based on the experience of professors who provide APT. Methods This is a cross-sectional, descriptive study with a quantitative approach. Twenty-two professors answered an online questionnaire containing 31 items related to APT, involving items about the professional profile, conditions for APT in undergraduate and postgraduate courses in Speech Therapy, APT structure, and evaluation of the APT effect. Result it was observed that there is a variation in APT procedures performed in Brazil. The main requirements indicated by the respondents for the APT involve the use of synthesized voices in the initial moments, followed by human voices later; the use of speech tasks with sustained vowels and connected speech; the insertion of complementary information such as gender, age, the profession of the speaker and the spectrography of the vocal signal; training with a minimum time of six hours; the evaluation of the training effect by comparing intra- and inter-judge agreement before and after training; the addition of the parameters of general degree of vocal deviation, roughness, breathiness, and strain; the use of validated continuous and numerical scales; and offering it from the second year of the undergraduate program. Conclusion although there is variability in the response of experts, a minimum set of requirements indicated for performing APT with new judges was identified.

Conclusão embora haja uma variabilidade da resposta dos especialistas, foi identificado um conjunto mínimo de requisitos indicados para a realização de TPA com novos juízes.

Abstract Introduction: evidence has shown a relationship between obesity and binge eating disorder (BED) as well as differences in dietary pattern. The objective was to establish the risk of BED in NUTRITION and dietetics consultations (N&D) and its relationship with dietary pattern. Methods: a cross-sectional study in 113 people who attended the N&D clinic to lose weight. They completed the BES questionnaire, a food consumption frequency questionnaire, and anthropometric measurements were taken. A descriptive analysis of the variables was performed, and an attempt was made to establish a relationship between the different explanatory variables and risk of BED. Results: 35.3 % of subjects were at risk for BED. The variables that showed significant differences for risk of BED were sex (p = 0.047), BMI (p < 0.001), previous diagnosis of eating disorder (p = 0.002), cabrohydrate intake higher than recommendations (p < 0.001), and protein intake lower or equal than recommendations (p < 0.001). In the adjusted logistic regression model the variables finally included were BMI, OR = 1.2 (95 % CI, 0.8-1.4, p = 0.02), cabrohydrate intake higher than recommendations, OR = 1.4 (95 % CI, 0.1-2.8, p = 0.02), and protein intake lower or equal than recommendations, OR = 1.2 (95 % CI, 0.4-4.1, p = 0.04). Conclusion: the risk of BED in overweight patients who come to consult for weight loss is high. There is a relationship between this risk and dietary pattern. Other similar studies are required.

Resumen Introducción: la evidencia ha mostrado relación entre la obesidad y el trastorno por atracones (TPA) y diferencias en el patrón dietético. El objetivo fue establecer el riesgo de TPA en las consultas de nutrición y dietética (NyD) y su relación con el patrón dietético. Métodos: estudio transversal sobre 113 personas que acudieron a consulta de NyD para perder peso. Se seleccionaron aquellas que acudían a su primera consulta. Cumplimentaron el cuestionario Binge Eating Scale (BES), un cuestionario de frecuencia de consumo de alimentos, y se tomaron medidas antropométricas. Se realizó el análisis descriptivo de las variables y se trató de establecer una asociación entre las diferentes variables explicativas con el riesgo de TPA. Resultados: el 35,3 % de los individuos presentaron riesgo de TPA. Las variables que mostraron diferencias significativas para el riesgo de TPA fueron el sexo (p = 0,047), el IMC (p < 0,001), el diagnóstico previo de TCA (p = 0,002), la ingesta de carbohidratos superior a las recomendaciones (p < 0,001) y la ingesta de proteínas igual o inferior a las recomendaciones (p < 0,001). En el modelo de regresión logística ajustado, las variables incluidas finalmente fueron: IMC, OR = 1,2 (IC 95 %: 0,8-1,4; p = 0,02); ingesta de carbohidratos superior a las recomendaciones, OR = 1,4 (IC 95 %: 0,1-2,8; p = 0,02); e ingesta de proteínas igual o inferior a las recomendaciones, OR = 1,2 (IC 95 %: 0,4-4,1; p = 0,04). Conclusión: el riesgo de TPA en los pacientes con sobrepeso que acuden a consulta para pérdida de peso es elevado. Existe relación entre este riesgo y el patrón dietético. Es necesario realizar otros trabajos similares.

Abstract: Objective: To evaluate the effectiveness of a multidisciplinary online intervention (psychological, medical, and nutritional) in women with binge eating disorder (BED). Method: 5 women diagnosed with BED with a mean age of 43.2 years and a mean initial body weight of 90 kg participated. The treatment was carried out during 24 sessions, each of two hours per week; the first hour was group therapy and the second individual. There were four moments of evaluation: pre, post and two follow-ups. Results: The comparisons were made through the non-parametric Friedman test, finding a statistically significant decrease in binge eating symptoms before χ1= 30.30 at the second follow-up χ2 =10.80 (x2=12.84; p=.005), symptoms of anxiety χ1= 28.80, χ2=12.40 (x2=10.83.96; p=.013) and depression χ1= 19.80, χ2=4.0 (x2= 10.18, p=.017). Improvement was observed in comprehension χ1= 21.00, χ2=30.20 (x2=9.63; p=.025) and emotional regulation χ1= 28.40 χ2=33.00, (x2=7.77; p=.050). The patients reduced their body weight, improved their eating habits by introducing fruit and vegetables daily and included physical activity in their daily routine, performing 20 to 30 minutes a day. From the objective clinical change, a positive change was observed in the variables addressed in treatment in all the participants. Conclusions: The online multidisciplinary intervention was effective in the treatment of BED in women.

Las pacientes redujeron su peso corporal, mejoraron hábitos alimentarios introduciendo fruta y verdura diariamente e incluyeron la actividad física en su rutina diaria, realizando de 20 a 30 minutos diarios. A partir del cambio clínico objetivo se observó un cambio positivo en las variables abordadas en tratamiento en todas las participantes. Conclusiones: Se puede observar que la intervención multidisciplinaria en línea fue efectiva en el tratamiento de TpA en mujeres.

Resumen Objetivo: determinar el gasto energético y el tiempo dedicado a actividad física en condición de vida libre de escolares costarricenses con sobrepeso u obesidad. Metodología: participaron 31 niños y 13 niñas entre 6 y 9 años (7.6 ± 1.03 años) con sobrepeso u obesidad, estado nutricional que se estableció según el IMC. Las variables del estudio fueron la antropometría, el porcentaje de grasa corporal (%GC), el gasto energético total producto de la actividad física a lo largo del día (GEAF total diario), el gasto energético por actividad física (GEAF) y el tiempo dedicado a la actividad física (TAF), las dos últimas se estimaron según condición sedentaria, ligera, moderada o vigorosa, por medio del acelerómetro Actiheart. Resultados: la talla y el %GC fueron significativamente mayores en las niñas (126.8 ± 5.9 cm, 34.0 ± 6.4 %GC) que en los niños (123.0 ± 5.4 cm, 25.2 ± 6.9 %GC). Los niños registraron un GEAF total diario de 824 ± 228.1 kcal/day, GEAF moderada + vigorosa de 285.6 ± 131.7 kcal/day y un TAF moderada + vigorosa de 147.0 ± 66.6 min, valores superiores (p<0.05) a los de las niñas 395 ± 144.4 kcal/day, 139.6 ± 90.1 kcal/day y 75.6 ± 43.2 min, respectivamente. Conclusiones: los escolares cumplen más de los 60 min/día recomendados de TAF de moderada a vigorosa intensidad, sin embargo, el GEAF de moderada a vigorosa intensidad no alcanza el mínimo de 300 kcal/día para la reducción de peso, lo cual podría ser una de las causas del sobrepeso.

Abstract Objective: To determine the energy expenditure and time spent on physical activities in Costa Rican overweight or obese schoolchildren in free-living conditions. Methodology: Participants were 31 boys and 13 girls aged 6 to 9 years old (7.6 ± 1.03 years) with overweight or obesity; nutritional status was established by BMI. The variables of the study were: anthropometric, body fat percentage (%BF), total energy expenditure product of physical activity performed during the day (EEPA daily total), plus the energy expenditure by physical activity (EEPA), and time spent on physical activity (TPA), both variables in sedentary condition, light, moderate and vigorous intensity estimated by the Actiheart accelerometer. Results: Size and %BF were significantly higher in girls (126.8 ± 5.9 cm, 34.0 ± 6.4% BF) than in boys (123.0 ± 5.4 cm, 25.2 ± 6.9% BF). Boys recorded a daily total EEPA of 824 ± 228.1 kcal / day, moderate + vigorous EEPA 285.6 ± 131.7 kcal / day and a moderate + vigorous TPA 147.0 ± 66.6 min; significantly higher (P <0.05) than girls 395 ± 144.4 kcal / day, 139.6 ± 90.1 kcal / day and 75.6 ± 43.2 min respectively . Conclusions: Schoolchildren perform over 60 min/day moderate to vigorous intensity PA recommended, however; the EEPA moderate to vigorous intensity does not meet the minimum recommendation of 300 kcal / day for weight reduction. This could be one of the causes for overweight schoolchildren.

RESUMO Background: Transformação hemorrágica (TH) é uma complicação frequente no acidente vascular cerebral (AVC) isquêmico independente do uso de terapia de reperfusão (TR). Diversos escores preditivos de TH foram elaborados. Entretanto, a maioria desses escores incluíram pacientes submetidos a TR — o que pode levar à má interpretação do risco de TH nos pacientes não submetidos a TR. Objetivo: Nosso objetivo é revisar escores preditivos já publicados e analisar a sua acurácia em nossa amostra. Métodos: Analisamos a acurácia de sete escores. Nosso banco foi criado de uma coorte de 1.565 pacientes consecutivos, admitidos entre 2015 e 2017 em um centro avançado de AVC. Os pacientes realizaram neuroimagem de controle em até sete dias. Uma comparação entre áreas abaixo da curva/característica de operação do receptor (AUC) foi realizada, analisando-se as diferenças entre grupos de pacientes tratados ou não com ativador de plasminogênio tecidual recombinante (tPA). Resultados: Nosso banco de dados proporcionou informação suficiente para avaliar sete escores, dos quais seis foram aplicados em pacientes tratados ou não com tPA. HAT (AUC 0,76), HTI (0,73) e SEDAN (0,70) foram os escores mais acurados em pacientes não tratados com tPA. SPAN-100 (0,55) teve a pior acurácia nos grupos. Três desses escores apresentaram diferentes valores de corte entre os grupos. Conclusões: Os escores apresentaram de boa a moderada acurácia na predição de TH em pacientes tratados com tPA. Três escores foram mais acurados em pacientes não tratados com tPA. A parametrização dessas características e a inclusão de mais pacientes não tratados com TR em um estudo multicêntrico poderia levar a escores mais acurados.

ABSTRACT Background: Hemorrhagic transformation (HT) is a complication in ischemic strokes, regardless of use of reperfusion therapy (RT). There are many predictive scores for estimating the risk of HT. However, most of them include patients also treated with RT. Therefore, this may lead to a misinterpretation of the risk of HT in patients who did not undergo RT. Objective: We aimed to review published predictive scores and analyze their accuracy in our dataset. Methods: We analyzed the accuracy of seven scales. Our dataset was derived from a cohort of 1,565 consecutive patients from 2015 to 2017 who were admitted to a comprehensive stroke center. All patients were evaluated with follow-up neuroimaging within seven days. Comparison of area under the curve (AUC) was performed on each scale, to analyze differences between patients treated with recombinant tissue plasminogen activator (tPA) and those without this treatment. Results: Our dataset provided enough data to assess seven scales, among which six were used among patients with and without tPA treatment. HAT (AUC 0.76), HTI (0.73) and SEDAN (0.70) were the most accurate scores for patients not treated with tPA. SPAN-100 (0.55) had the worst accuracy in both groups. Three of these scores had different cutoffs between study groups. Conclusions: The predictive scores had moderate to fair accuracy for predicting HT in patients treated with tPA. Three scales were more accurate for predicting HT in patients not treated with tPA. Through standardizing these characteristics and including more patients not treated with RT in a large multicenter series, accurate predictive scores may be created.

Abstract Seventy-two offspring pigs (150 d) from 27 sow (9 sows per group) fed different vitamin D3 levels were used to evaluate the effects of maternal vitamin D3 status and postmortem cold storage on cooking loss, color, texture profile analysis (TPA), low-field nuclear magnetic resonance (LF-NMR) T2 relaxation times and dynamic rheological of gel properties of chilled pork batters in offspring pigs. Sows were allotted to low, normal, and high dietary vitamin D3 groups which contained 200 (LD), 800 (ND), and 3200 (HD) IU of vitamin D3/kg basal diet, respectively. Results showed that HD group had higher a* value, hardness, cohesiveness, springiness, chewiness, and storage modulus (G') values, while had lower cooking loss, L* value, T21 and T22 relaxation time compared with LD group during postmortem cold storage period (P < 0.05). In addition, cold storage time increased cooking loss and b* values of LD and ND groups, TPA parameters, T22 relaxation time and G' values of all experimental groups, while decreased a* and L* values of LD and ND groups (P < 0.05). The results revealed that maternal high-dose vitamin D3 levels influenced these indicators of chilled pork batters in offspring pigs, which improved the quality attributes during postmortem cold storage.

Abstract The objective was to produce flour from sorghum grains, to determine the physicochemical and microbiological characteristics, and to develop different formulations of cookies, with total and partial replacement of rice flour, evaluating the moisture content, color, expansion factor and texture profile - TPA. Five formulations were processed, as follows: control - 0%; F1 - 25%; F2 - 50%; F3 - 75% and F4 - 100% sorghum flour. The sorghum flour showed physical, chemical and microbiological characteristics in accordance with current legislation, and can be inserted into human food. The different cookie formulations after baking had a moisture content below 7%. With the addition of sorghum flour, the cookies showed lower light F4 – 32.35 L*. The addition of sorghum flour did not affect the expansion factor of the cookies, with average value of 2.13. The different concentrations of sorghum flour, showed interference in analysis of the Texture-TPA profile, the F3 formulation, presented higher values of hardness 25594.44 N, fracturability 251 N, cohesiveness 0.27. Elasticity has not been compromised. The highest values of gumminess 53.08 N, chewability 1471.15 mJ were found in the formulation F4 – 100% FS. These results may help improve the quality of sorghum-based gluten-free foods for celiac consumers.

Resumo Contexto A maior sobrevida dos doentes dialíticos somada à incapacidade de obtenção de órgãos suficientes para atender a demanda, bem como à dificuldade de acesso aos serviços de saúde, levou ao aumento da fila para transplante e ao prolongamento do tempo de utilização do acesso venoso central para hemodiálise. A etiologia mais comum de estenose de veia central é o acesso venoso central prolongado, pelas lesões intimais decorrentes da presença do cateter. Objetivos Avaliar resultados de angioplastia para tratamento de doença oclusiva venosa central com fístula arteriovenosa periférica funcionante. Métodos Estudo tipo coorte retrospectivo com revisão de prontuários de 47 doentes com lesões estenóticas ou oclusivas. A avaliação dos doentes foi realizada em 30 dias, 6 meses e 1 ano após a recanalização ou correção da estenose com ATP ou ATP/aplicação de stent. Resultados Lesões estenóticas foram encontradas em 25 doentes (53%), e oclusões, em 22 (47%) doentes. A angioplastia percutânea transluminal (ATP) com stent foi utilizada em 64% dos doentes, e angioplastia isolada com balão, em 36% deles. A análise de resultados clínicos mostrou elevada taxa de melhora clínica precoce (30 dias) em 82% dos doentes (intervalo de confiança [IC] 71-93%). Após 1 ano de seguimento, a taxa de perviedade primária foi de 57%, e a taxa de perviedade primária assistida foi de 72% (IC 57-84%). Conclusão O tratamento endovascular das estenoses ou oclusões de veia central sugere melhora clínica dos sintomas e taxas adequadas de perviedade no período de 1 ano, apesar da limitação no tamanho amostral.

Abstract Background The increased survival of dialysis patients and the inability to obtain sufficient organs to meet demand for transplantation, compounded by poor access to health services, have caused the transplant waiting lists to grow, extending the time spent using central venous accesses for hemodialysis. The most common etiology of central vein stenosis is prolonged central venous access, due to intimal injuries caused by the presence of the catheter. Objectives To assess the results of angioplasty to treat central vein occlusion in patients with functioning peripheral arteriovenous fistulas. Methods Retrospective cohort study with review of medical records from 47 patients with stenotic or occlusive lesions. Patients were assessed at 30 days, 6 months, and 1 year after recanalization or correction of stenosis with transluminal percutaneous angioplasty (TPA) or TPA/stenting. Results Stenotic lesions were detected in 25 patients (53%) and occlusions were found in 22 (47%) patients. TPA with stenting was used in 64% of patients and balloon angioplasty in isolation was used in 36%. Analysis of clinical results showed a high rate of early clinical improvement (30 days), seen in 82% of patients (confidence interval [CI] 71-93%). After 1 year of follow-up, the primary patency rate was 57% and the assisted primary patency rate was 72% (CI 57-84%). Conclusions Endovascular treatment of central vein stenosis or occlusions suggests clinical improvement of symptoms and adequate rates of patency at 1 year, notwithstanding the limited sample size.

The aim of this study was to verify the relationship between quantitative T2 relaxation measurements of lumbar intervertebral discs (IVDs) and spinopelvic parameters in patients with chronic low back pain. The study was approved by the Clinical Hospital of the Ribeirao Preto Medical School (USP) Ethics Committee, and written consent was obtained from all patients. A total of 455 IVDs from 91 consecutive patients with chronic low back pain were included in this prospective study. All subjects were assessed using the Oswestry Disability Index and visual analogue scale questionnaires and were confirmed to have no other spine diseases except disc degeneration. Spinopelvic parameters including the pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), sagittal vertical axis (SVA), global tilt (GT), T1 pelvic angle (TPA), lumbar lordosis (LL), thoracic kyphosis (TK), pelvic incidence minus lumbar lordosis mismatch (PI-LL), and lack of lumbar lordosis (LLL) were measured. The study group was categorized according to the Roussouly classification. Sagittal T2 maps were acquired to extract the IVD relaxation times, and the complete manual segmentation of IVDs at all levels was performed using Display® software. Lumbar IVD T2 relaxation times showed significant correlation with PT (P<0.01), GT (P<0.01), TPA (P<0.01), PI-LL (P=0.01), and LLL (P=0.01). No difference was noted between Roussouly subtypes regarding T2 relaxation times at any disc level. Data from questionnaires showed no correlation with T2 relaxation times. Global tilt and T1 pelvic angle were correlated with IVD composition changes (T2 relaxometry). There was no correlation between clinical symptoms and IVD T2 relaxation times.

ABSTRACT Introduction: Treponema pallidum is considered as a monomorphic bacterium with very few genomic differences among isolates and subspecies. The genetic diversity of this pathogen has not been explored in depth; however, this kind of studies potentially has a direct impact on the development of new diagnostic methods and vaccines. The objective of this work was to evaluate the genetic diversity of this pathogen in Cuba (2012-2019). Methods: Five exploratory studies were carried out based on molecular characterization, detection of one-off mutations and whole genome sequencing of T. pallidum. Results: The high level of genetic diversity of T. pallidum in the Cuban context was demonstrated by the detection of 8 subtypes of T. pallidum subsp. pallidum (TPA), 7 genotypes of TPA, the identification of T. pallidum subsp. endemicum in patients diagnosed with venereal syphilis, one-off mutations conferring resistance to macrolides with a high frequency and intra- and inter-strain recombination events in TPA. These findings suggest, as a conclusion, a significant genetic diversity of T. pallidum in the Cuban context with an increased predominance of recombinant genotypes over time, which should be further studied given their potential involvement in the development of this disease.

RESUMEN Introducción: Treponema pallidum es una bacteria monomórfica con muy pocas diferencias genómicas entre aislados y subespecies. La diversidad genética de este patógeno no ha sido explorada a profundidad, sin embargo, estos estudios impactan directamente en el desarrollo de nuevos métodos diagnósticos, vacunas, entre otros. El objetivo de este trabajo fue evaluar la diversidad genética de este patógeno en Cuba (2012-2019). Métodos: Se realizaron 5 estudios moleculares exploratorios basados en caracterización molecular, detección de mutaciones puntuales y secuenciación de genoma completo de T. pallidum. Resultados: Se determinó la presencia de 8 subtipos de T. pallidum subsp. pallidum (TPA), 7 genotipos de TPA, la presencia de T. pallidum subsp. endemicum en pacientes diagnosticados de sífilis venérea, con mutaciones puntuales de resistencia a macrólidos en una elevada frecuencia y eventos de recombinación intra e inter-aislados en TPA aportando significativamente a la diversidad genética de este patógeno en Cuba y en el mundo. Lo anterior, sugiere como conclusión una significativa diversidad genética de T. pallidum en el contexto cubano con un predominio incrementado en el tiempo de genotipos recombinantes, a los que se les debe seguir más de cerca por su potencial implicación en el comportamiento de esta enfermedad.

ABSTRACT Motivated by the lack of studies that standardize and optimize the parameters of texture tests, this study aimed to determine the operating conditions for TPA to maximize the discrimination among samples of fruit preserves. The texture of the commercial guava preserves was evaluated using a texturometer. The Design Central Composite Rotational (DCCR) method was applied with four independent variables: speed test, sample volume, time between compression cycles and compression percentage. Only the compression percentage and test speed were significantly influenced by the texture parameters evaluated. The optimum operating region of TPA to better discriminate differences in texture parameters depended on the variable to be optimized, and for adhesiveness a compression of 75% and a compression speed of 0.23 mm·s are recommended. To detect differences among the samples for the parameters of cohesiveness, gumminess and resilience, the use of 15% compression and 2.59 mm·s speed is suggested. In both cases, one must employ the shortest time between two cycles and use a smaller sample size to save both the time of analysis and of the sample, respectively. For the parameters of hardness, elasticity and chewiness, optimal regions were not identified.

Abstract Acute ischemic stroke (AIS) is a time-dependent emergency, since the greatest impact depends on the time elapsed to treatment. The objective of this work was to analyze door to needle (DTN) and start treatment (STT) times and the effect of pre-notification system (PNS) and the appropriate choice of the healthcare center on these variables. An observational study with data obtained from records of patients admitted to the Stroke Unit (SU) was conducted between August 2015 to December 2019. We analyzed the number of intravenous thrombolytic treatments (IVT), DTN and STT and compared them according to PNS use, direct arrival at the center with SU or arrival at another center for subsequent referral. An overall of 472 patients were hospitalized during the studied period and the treatment was performed in 143 out of 265 patients. One hundred thirty-seven patients arrived from another center, 70 received IVT. Average DNT with PNS and without PNS were 41 ± 23 and 81 ± 44 minutes, respectively (p = 0.001). STT on direct arrival to SU was 159 ± 59 minutes and to another center for referral was 199 ± 44 (p = 0.001). The use of a PNS and the direct choice of a center where IVT is performed significantly improve treatment

Resumen El accidente cerebrovascular (ACV) es una urgencia tiempo dependiente, ya que las conductas de mayor impacto pronóstico dependen del tiempo trascurrido. El objetivo de este trabajo fue analizar nuestros tiempos puerta aguja (TPA), comienzo aguja (TCA) y el efecto que tiene sobre estos el sistema preaviso y la elección adecuada del centro asistencial. Se realizó un estudio observacional con datos obtenidos de histo rias clínicas de pacientes internados en la unidad de ACV. Analizamos el número de tratamientos trombolíticos endovenosos, entre agosto 2015 y diciembre 2019. Comparamos TPA según utilización de pre-aviso, llegada directa por sus propios medios vs. en ambulancia sin pre-aviso, y TCA según llegada directa al centro con unidad de ACV vs. llegada a otro centro para posterior derivación. De 265 pacientes en ventana terapéutica, se realizó tratamiento en 143. Llegaron 137 pacientes derivados de otro centro, 70 recibieron tratamiento trombolítico. El TPA con sistema preaviso y sin preaviso fue 41 ± 23 (media ± DE) y 81 ± 43 minutos, respectivamente (p = 0.001). El TPA con llegada directa por sus propios medios 79 ± 43 y en ambulancia sin preaviso 84 ± 44 minutos (p = 0.7) a unidad de ACV. El TCA en llegada directa a unidad de ACV fue 159 ± 59 y a otro centro para su derivación 199 ± 44 minutos (p = 0.001). La utilización de un sistema de preaviso y la elección directa de un centro con unidad de ACV son medidas clave para reducir los tiempos de tratamiento.
