RESUMO
Introducción: En modelos de producción vocal que emplean estructuras de resorte-masa-amortiguador, la precisión en la determinación de coeficientes de amortiguamiento que se asemejen a las características fisiológicas de las cuerdas vocales es crucial, teniendo en cuenta posibles variaciones en la representación de la viscoelasticidad. Objetivo: Este estudio tiene como objetivo realizar un ajuste paramétrico de un modelo de producción vocal basado en un sistema de resorte-masa-amortiguador que incorpora interacción con la presión subglótica, con el fin de modelar de manera precisa las fuerzas de colisión ejercidas por las cuerdas vocales durante la fonación. Método: Se utilizó un algoritmo de búsqueda metaheurística para la síntesis paramétrica. El algoritmo se aplicó a los coeficientes de elasticidad c1 y c2, así como a los coeficientes de amortiguamiento ε1 y ε2, que se correlacionan directamente con las matrices de masa del modelo. Esto facilita el ajuste de la composición de las cuerdas para lograr un comportamiento fisiológico deseado. Resultados: El comportamiento del sistema vocal para cada ciclo de simulación se comparó con un estándar predefinido en condiciones normales. El algoritmo determinó el punto final de la simulación evaluando las discrepancias entre características clave de las señales obtenidas y las deseadas. Conclusión: El ajuste paramétrico permitió la aproximación del comportamiento fisiológico de la producción vocal, proporcionando estimaciones de las fuerzas de impacto experimentadas por las cuerdas vocales durante la fonación.
Introduction: In vocal production models employing spring-mass-damper frameworks, precision in determining damping coefficients that align with physiological vocal fold characteristics is crucial, accounting for potential variations in the representation of viscosity-elasticity properties. Objective: This study aims to conduct a parametric fitting of a vocal production model based on a mass-spring-damper system incorporating subglottic pressure interaction, with the purpose of accurately modeling the collision forces exerted by vocal folds during phonation. Method: A metaheuristic search algorithm was employed for parametric synthesis. The algorithm was applied to elasticity coefficients c1 and c2, as well as damping coefficients ε1 and ε2, which directly correlate with the mass matrices of the model. This facilitates the adjustment of fold composition to achieve desired physiological behavior. Results: The vocal system's behavior for each simulation cycle was compared to a predefined standard under normal conditions. The algorithm determined the simulation endpoint by evaluating discrepancies between key features of the obtained signals and the desired ones. Conclusion: Parametric fitting enabled the approximation of physiological vocal production behavior, providing estimates of the impact forces experienced by vocal folds during phonation.
RESUMO
PURPOSE: Considering the conceptual migration from vocal load and vocal loading to vocal demand and vocal demand response, this review of literature aimed to identify physiological explanations, reported measurements, and associated factors (vocal demands) reported in the literature when considering the phonatory response to a vocal demand. METHODS: A systematic review of literature, following the PRISMA Statement, was conducted using Web of Science, PubMed, Scopus, and ScienceDirect. Data were analyzed and presented in two parts. First, a bibliometric analysis, co-occurrence analysis, and content analysis were performed. Three criteria that got article inclusion were defined: (1) written in English, Spanish, and Portuguese; (2) published between 2009 and 2021; and (3) focused on vocal load and loading, vocal demand response, and voice assessment parameters. A total of 54 publications met the criteria and were included in this review. The second part included a conceptual framework based on the content analysis of three aspects of vocal demand response: (1) physiological explanations, (2) reported measurements, and (3) vocal demands. RESULTS AND CONCLUSION: As would be expected since vocal demand response is a relatively new term and not yet commonly used in literature when discussing way that the speakers respond to communicative scenarios, most of the studies reviewed (both historical and recent) still use the term of vocal load and vocal loading. Although there is a broad variety of literature discussing a wide range of vocal demands and voice parameters used to characterize the vocal demand response, results show that there is consistency across the studies. While vocal demand response is unique and intrinsic to the talker, associated factors that contribute to this response include both internal talker and external talker factors. Internal factors include muscle stiffness, viscosity in the phonatory system, vocal fold tissue damage, elevated sound pressure levels during occupational voice demands, extended periods of voice use, suboptimal body posture, difficulties in breathing technique, and sleep disturbances. Associated external factors include the working environment (noise, acoustics, temperature, humidity). In conclusion, although vocal demand response is intrinsic to the speaker, the speaker's response is affected by external vocal demands. However, due to the wide methods to evaluate vocal demand response, it has been difficult to establish its contribution to voice disorders in the general population and, specifically, among occupational voice users. This literature review identified commonly reported parameters and factors that may help clinicians and researchers define vocal demand response.

The contamination of aquatic environments by microplastic has become a major threat to biodiversity. The presence of microplastic is documented in the aquatic fauna of the oceans, but, in the Amazon basin, reports on microplastic occurrence are few. The present study surveyed microplastic occurrence in fishes in an area of the Peruvian Amazon. We sampled 61 specimens of 15 commercial species from local markets in the city of Iquitos, Loreto Department. We detected a total of 2337 microplastic particles, 1096 in the gills and 1241 in the internal organs (esophagus, stomach, intestine, liver, gonads, pancreas, swim bladder and heart). The prevalence of microplastic particles was 100% and the overall average abundance was of 38.3 particles per individual (17.9 particles per individual in gills and 20.3 particles per individual in internal organs). Most particles were found in carnivorous fish. There was no correlation of particle abundance with fish standard length and weight. These results provided evidence of the degree of microplastic contamination of the fish fauna in the region of Iquitos.(AU)
La contaminación de ambientes acuáticos por microplásticos se ha convertido en una gran amenaza para la biodiversidad. La presencia de microplásticos está bien documentada en la fauna acuática de los océanos, pero en la cuenca del Amazonas hay pocos reportes de ocurrencia. En este trabajo se investigó la ocurrencia de partículas de microplásticos en peces de un área de la Amazonía peruana. Se obtuvieron 61 especímenes de 15 especies comerciales provenientes de los mercados locales de la ciudad de Iquitos. Se detectó un total de 2337 partículas de microplástico, 1096 en las branquias y 1241 en los órganos internos (esófago, estomago, intestinos, hígado, gónadas, páncreas, vejiga natatoria y corazón). La prevalencia de partículas de microplástico fue del 100% y la abundancia general de partículas de microplástico fue de 38.3 partículas por individuo (17.9 partículas por individuo en las branquias y 20.3 partículas por individuo en los órganos internos). La mayor cantidad de particulas fué encontrada en peces carnivoros. No hubo correlación entre la abundancia de las particulas y el tamaño estandar y peso de los peces. Estos resultados proporcionan evidencia de los niveles de contaminación por microplásticos en la fauna de peces amazónica en la región de Iquitos.(AU)

A comparative single-evaluation cross-sectional study was performed to evaluate cognitive damage in post-COVID-19 patients. The psychophysics tests of Two-Alternative Forced Choice (2AFC) and Simple Reaction Time (SRT), under a designed virtual environment, were used to evaluate the cognitive processes of decision-making, visual attention, and information processing speed. The population under study consisted of 147 individuals, 38 controls, and 109 post-COVID patients. During the 2AFC test, an Emotiv EPOC+® headset was used to obtain EEG signals to evaluate their Focus, Interest, and Engagement metrics. Results indicate that compared to healthy patients or recovered patients from mild-moderate COVID-19 infection, patients who recovered from a severe-critical COVID infection showed a poor performance in different cognitive tests: decision-making tasks required higher visual sensitivity (p = 0.002), Focus (p = 0.01) and information processing speed (p < 0.001). These results signal that the damage caused by the coronavirus on the central nervous and visual systems significantly reduces the cognitive processes capabilities, resulting in a prevalent deficit of 42.42% in information processing speed for mild-moderate cases, 46.15% for decision-making based on visual sensitivity, and 62.16% in information processing speed for severe-critical cases. A psychological follow-up for patients recovering from COVID-19 is recommended based on our findings.
RESUMO
Objective: The prevalence of diabetes mellitus in Mexico is very high. This study aimed to compare the risk factors of diabetes mellitus in Mexican adults in 2003 and in 2014. Methods: This study had a repeated cross-sectional design. Data from the World Health Organization (WHO) Study on global AGEing and adult health (SAGE) from Mexico (Wave 0, 2003, and Wave 2, 2014) were compared. Self-reported diabetes mellitus (outcome) was evaluated with the yes/no question: "Have you ever been diagnosed with diabetes mellitus (high blood sugar)?" Bivariate analyses and multivariable logistic regression analyses adjusted for potential risk factors were conducted. Results: In 11 years (2003-2014), the prevalence of self-reported diabetes mellitus in Mexican adults increased by 2.6 times in those younger than 50 years (2003: 2.1%; 2014: 5.5%) and by 1.9 times in those ≥50 years (2003: 12.7%; 2014: 24.2%). In 2003, the risk factors associated with diabetes mellitus were female sex (OR 1.344, 95% CI 1.176-1.536), age ≥50 years (OR 6.734, 95% CI 5.843-7.760), being overweight (OR 1.359, 95% CI 1.175-1.571), obesity (OR 1.871, 95% CI 1.583-2.211), and lower physical activity of <600 MET-minutes/week (OR 1.349, 95% CI 1.117-1.630). In 2014, the exposure characteristics significantly associated with diabetes mellitus were female sex (OR 1.244, 95% CI 1.025-1.511), older age ≥50 years (OR 4.608, 95% CI 3.260-6.515), being overweight (OR 1.649, 95% CI 1.305-2.083), obesity (OR 1.778, 95% CI 1.398-2.261), and in those who had not attended/completed primary school (OR 1.360, 95% CI 1.042-1.773). Conclusion: The prevalence of diabetes mellitus in Mexico significantly increased from 2003 to 2014. Female sex, age older than 50 years, and being overweight or obese were significant risk factors in both 2003 and 2014. Not having completed primary school was a new significant risk factor in 2014. Public health policies and strategies should prioritize decreasing the high levels of overweight and obesity, and improve health literacy in Mexico.
RESUMO
Background: The Khorana risk score (KRS) for prognosis of venous thromboembolism (VTE) has been rarely explored in Hispanic populations. Objective: To determine the value of the KRS for prediction of VTE and overall survival (OS) among Hispanic individuals with cancer. Methods: We retrospectively evaluated all outpatients with newly diagnosed solid tumours receiving systemic chemotherapy in Hospital San Juan Dios, San José, Costa Rica, from January to December 2021. The 6-month cumulative VTE incidence according to the KRS categories was estimated using the Fine & Gray competing risk model. A Kaplan-Meier analysis was used to compare OS among KRS categories. The Cox regression analysis was performed to calculate the hazard ratio (HR) and its corresponding 95% confidence interval (CI). The receiver operating characteristic (ROC) analysis was performed to identify the optimal cutoff value to predict VTE during follow-up. Results: A total of 708 patients were included in the analysis. After a median follow-up of 8.13 months, the cumulative incidence of VTE at 6 months was 1.56% (95% CI: 0.83%-6.82%), 4.83% (95% CI: 2.81%-7.66%) and 8.84% (95% CI: 4.30%-15.42%) for low-, intermediate- and high-risk Khorana score categories, respectively (Gray's p value: 0.0178). The optimal cutoff for the KRS to predict VTE was 2 (area under the ROC curve: 0.65; 95% CI: 0.55-0.756). The KRS was independently associated with overall mortality (HR: 1.83; 95% CI: 1.46-2.29; p < 0.001, for the comparison of 'high-risk' and 'low-risk' KRS). Conclusions: The KRS is a valid tool to predict VTE and mortality in a cohort of Hispanic outpatients with newly diagnosed solid tumours.

Introducción. Los docentes son usuarios ocupacionales de la voz con alto riesgo de desarrollar patologías vocales a causa de su labor. Para enfrentar esta proble-mática, suelen usarse ejercicios con tracto vocal semiocluido (TVSO), estrategia de educación/rehabilitación empleada para generar un cambio en el patrón de vibración de los pliegues vocales, minimizando el riesgo de lesión vocal al reducir el estrés de colisión al que se someten los tejidos. Diversos reportes han indicado que este tratamiento tiene efectos en el cociente de cierre (CQ), medida indirecta del estrés de colisión.Objetivo. Examinar el efecto fisiológico de dos ejercicios con TVSO en la actividad laríngea de profesores con esfuerzo vocal constante pero sin patología vocal. Metodología. Se registraron muestras de 43 profesores antes, durante y después de la realización de dos ejercicios con TVSO (vibración lingual y fonación en tubos). Las muestras de electroglotografía se analizaron para obtener el CQ. Resultados y conclusión. Se observó una diferencia significativa al comparar los valores del CQ antes y durante la realización de ambos ejercicios. No se encontraron cambios en este parámetro después de ejecutar la actividad. Estos hallazgos concuer-dan con reportes previos en los cuales el CQ tiende a aumentar durante la fonación en tubos; contrariamente, la realización de la vibración lingual tiende a decrecer el valor del CQ. Es posible que este comportamiento se deba a los mecanismos biome-cánicos particulares de cada ejercicio
Introduction. Teachers are occupational voice users with high risk of developing vocal pathologies due to their work. To face this situation, it is common the use of semi-occluded vocal tract (SOVT) exercises, a strategy of voice education/rehabil-itation implemented to induce a change in the vibration pattern of the vocal folds, mitigating, therefore, the risk of vocal lesion by reducing the collision stress applied to tissues. A variety of reports have indicated that this treatment has effects in the closed quotient (CQ), an indirect measure of collision stress. Aim. The purpose of this study was to examine the physiological effect of two dif-ferent SOVT exercises in larynx activity of teachers with constant vocal effort but without vocal pathology. Methods. 43 samples of teachers were recorded before, during and after executing two SOVT exercises (tongue trill and tube phonation). Electroglottographic samples were analyzed in order to obtain CQ. Results and conclusion. Both exercises had a significant difference of CQ scores when before and during conditions were compared. Any difference was found on this parameter after executing the activity. These findings agree with previous reports where CQ tends to increase during phonation through resonance tubes; on the con-trary, execution of tongue trill tends to decrease CQ values. This behavior might be because of the particular biomechanical mechanisms of each exercise

Posterior a la reespecificación del modelo (M2), la sman quedo conformada por 5 factores y 18 ítems. Conclusión: la sman posee propiedades psicométricas destacables y confiables para la medición de la adherencia en poblaciones con déficit funcional asociado a condición neurológica.
Abstract Objective: To determine the construct validity of the Scale to Measure Adherence to functional Neurorehabilitation processes (SMAN) in adults. Methodology: Instrumental study, with a cross-sectional design, in which the confirmatory factor analysis method was used for an initial model of 5 factors and 20 items. The maximum likelihood method was used and univariate, and multivariate normality tests were performed. The hypothesized model was evaluated with absolute, incremental and parsimony adjustment measures. For the definitive model, reliability and convergent and discriminant validity were calculated through a correlation matrix. Results: For the initial model (M0), the modification indices showed cross-loading related to constructs of "disability" and "patient". Therefore, a theoretical review of instrument items was made, and two redundant items were eliminated, one in each factor. After model re-specification (M2), SMAN was constituted by 5 factors and 18 items. Conclusion: SMAN has remarkable and reliable psychometric properties to measure adherence in populations with functional deficits associated with neurological conditions.

Hypomyelination with atrophy of the basal ganglia and cerebellum (H-ABC) is a neurodegenerative disease due to mutations in TUBB4A. Patients suffer from extrapyramidal movements, spasticity, ataxia, and cognitive deficits. Magnetic resonance imaging features are hypomyelination and atrophy of the striatum and cerebellum. A correlation between the mutations and their cellular, tissue and organic effects is largely missing. The effects of these mutations on sensory functions have not been described so far. We have previously reported a rat carrying a TUBB4A (A302T) mutation and sharing most of the clinical and radiological signs with H-ABC patients. Here, for the first time, we did a comparative study of the hearing function in an H-ABC patient and in this mutant model. By analyzing hearing function, we found that there are no significant differences in the auditory brainstem response (ABR) thresholds between mutant rats and WT controls. Nevertheless, ABRs show longer latencies in central waves (II-IV) that in some cases disappear when compared to WT. The patient also shows abnormal AEPs presenting only Waves I and II. Distortion product of otoacoustic emissions and immunohistochemistry in the rat show that the peripheral hearing function and morphology of the organ of Corti are normal. We conclude that the tubulin mutation severely impairs the central hearing pathway most probably by progressive central white matter degeneration. Hearing function might be affected in a significant fraction of patients with H-ABC; therefore, screening for auditory function should be done on patients with tubulinopathies to evaluate hearing support therapies.

A clear understanding of the origin and role of the different subtypes of the B cell lineage involved in the activity or remission of multiple sclerosis (MS) is important for the treatment and follow-up of patients living with this disease. B cells, however, are dynamic and can play an anti-inflammatory or pro-inflammatory role, depending on their milieu. Depletion of B cells has been effective in controlling the progression of MS, but it can have adverse side effects. A better understanding of the role of the B cell subtypes, through the use of surface biomarkers of cellular activity with special attention to the function of memory and other regulatory B cells (Bregs), will be necessary in order to offer specific treatments without inducing undesirable effects.

ABSTRACT Objective Evaluate the effectiveness of structural or multicomponent interventions aimed at increasing the use of condoms in adolescents and young adults, identifying the strategies that form the interventions evaluated, and recognizing the theoretical models that support these interventions. Methodology Design: Systematic review of literature. Data source: MEDLINE databases were consulted via OVID, Embase, and CENTRAL in order to search for studies on interventions aimed at increasing the use of condoms in adolescents and young adults. Selection of studies: A total of 7 primary investigations were selected, in which the effect of a structured or multicomponent intervention to increase the use of condoms in adolescents and young adults was evaluated. The quality of the studies was evaluated using the Cochrane bias risk assessment. Results Five investigations show changes in the percentages of condom use with values between 53% and 68%. The interventions targeted guided their actions more at individual level with strategies such as sexual health education, reproductive health counseling, knowledge about the condom, knowledge about STIs / HIV, than at organizational and environ-mental levels, which were aimed at the provision of condoms. The theoretical models proposed in the studies are focused on human behavior, individual behavior, and social learning. Conclusion Structural interventions that aim to increase the use of condoms in adolescents and young adults seem to show significant changes at individual level, but possible changes generated at both organization and environment levels are unknown.(AU)

Introducción: la severidad de una disfonía da cuenta del grado de alteración que tiene una voz en relación con todos los procesos fisiológicos involucrados con la producción del sonido. Es importante determinar el nivel de severidad a fin de establecer un programa con el conjunto de ejercicios que permitan una rehabilitación apropiada. Objetivo: comprender si el comportamiento de los diferentes parámetros aerodinámicos, electroglotográficos, acústicos y de autorreporte vocal permite o no determinar la severidad de una disfonía. Método: se evaluaron 55 sujetos con diferentes tipos de disfonía según pará-metros aerodinámicos, electroglotográficos, acústicos y de autorreporte vocal. La muestra fue dividida en 3 grupos de acuerdo con el grado de gravedad de la patología. Se aplicó un análisis de varianza para comparar el comportamiento de las variables dependientes en relación con los niveles de severidad de la disfonía. Con el fin de determinar las diferencias entre estos niveles, se aplicó la prueba Post hoc (Tukey) a las variables significativas. Resultados: es posible determinar el nivel de severidad de una disfonía a partir de parámetros acústicos como el CPP, HNR y el cociente de pendiente espectral 1/5-5/8Khz. También se puede hacer por medio de cuestionarios de autorreporte vocal como el VOISS, el VHI y el VTDS
Introduction: the severity of dysphonia shows the degree of alteration that a voice has in relation to all the physiological processes involved in the production of sound. It is essential to determine the level of severity to establish a program with the set of exercises required for a proper rehabilitation. Objective: to understand if the behavior of the different aerodynamic, electroglot-tographic, acoustic, and vocal self-report parameters allows, or not, to determine the severity of dysphonia. Method: 55 subjects with different types of dysphonia were evaluated according to aerodynamic, electroglottographic, acoustic, and vocal self-report parameters. The sample was divided into three groups in relation to the severity degree of the patho-logy. An analysis of variance was applied to compare the behavior of dependent variables with the severity levels of dysphonia. The Post hoc test (Tukey) was applied to the significant variables to determine the differences between the severity levels. Results: it is possible to determine the level of severity of dysphonia from acoustic parameters such as CPP, HNR, and the ratio of spectral slope 1 / 5-5 / 8Khz. It is also possible to use voice self-report questionnaires such as the VOISS, the VHI, and the VTDS

Resumen El quilotórax se produce ante la ruptura, desgarro u obstrucción del conducto torácico o sus afluentes principales, lo que resulta en la liberación de quilo al espacio pleural. Ocurre más frecuentemente asociado a trauma o a lesiones malignas; pero han sido descritas otras causas. El diagnóstico se obtiene mediante toracocentesis y la determinación de las concentraciones de triglicéridos y colesterol en el líquido pleural. Las complicaciones incluyen la desnutrición, inmunosupresión y compromiso respiratorio. El tratamiento puede ser conservador o agresivo en función de la situación clínica.
Abstract Chylothorax occurs when there is rupture, laceration or obstruction of the thoracic duct or its main tributaries, resulting in the release of chyle into the pleural space. It most commonly occurs from trauma or malignancy, but other causes have been described. Diagnosis involves thoracocentesis and cholesterol and triglyceride measurement in the pleural fluid. Complications include malnutrition, immunosuppression and respiratory distress. Treatment may be either conservative or aggressive depending on the clinical scenario.

Immunomodulatory therapies available for the treatment of patients with multiple sclerosis (MS) accomplish control and neutralization of peripheral immune cells involved in the activity of the disease cascade but their spectrum of action in the intrathecal space and brain tissue is limited, taking into consideration the persistence of oligoclonal bands and the variation of clones of lymphoid cells throughout the disease span. In animal models of experimental autoimmune encephalomyelitis (EAE), the presence of CXCL13 has been associated with disease activity and the blockade of this chemokine could work as a potential complementary therapeutic strategy in patients with MS in order to postpone disease progression. The development of therapeutic alternatives with ability to modify the intrathecal inflammatory activity of the meningeal tertiary lymphoid organ to ameliorate neurodegeneration is mandatory.
