ABSTRACT

Propósito Analizar el impacto de la enfermedad pulmonar obstructiva crónica (EPOC) y el asma bronquial sobre el manejo terapéutico y el pronóstico de los pacientes con insuficiencia cardiaca (IC). Métodos Análisis de la información contenida en un registro clínico de pacientes remitidos a una unidad especializada de IC entre enero de 2010 y junio de 2022. Se compararon su perfil clínico, el tratamiento y el pronóstico en base a la presencia de EPOC o asma bronquial. El análisis de supervivencia se realizó mediante los métodos de Kaplan-Meier y Cox. La mediana de seguimiento fue de 1.493 días. Resultados Se estudiaron 2.577 pacientes, de los cuales 251 (9,7%) presentaban EPOC y 96 (3,7%), asma bronquial. Observamos diferencias significativas entre los tres grupos con respecto a la prescripción de betabloqueantes (EPOC=89,6%; asma=87,5%; no broncopatía=94,1%; p=0,002) e inhibidores del cotransportador de sodio-glucosa tipo2 (EPOC=35,1%; asma=50%; no broncopatía=38,3%; p=0,036). Además, los pacientes con patología bronquial recibieron con menor frecuencia un desfibrilador (EPOC=20,3%; asma=20,8%; no broncopatía=29%; p=0,004). La presencia de EPOC se asoció de forma independiente con mayor riesgo de muerte por cualquier causa (HR=1,64; IC95%: 1,33-2,02), muerte u hospitalización por IC (HR=1,47; IC95%: 1,22-1,76) y muerte cardiovascular o trasplante cardiaco (HR=1,39; IC95%: 1,08-1,79) en comparación con la ausencia de broncopatía. La presencia de asma bronquial no se asoció a un impacto significativo sobre los desenlaces analizados. Conclusiones La EPOC, pero no el asma bronquial, es un factor pronóstico adverso e independiente en pacientes con IC. (AU)


Purpose To analyze the impact of chronic obstructive pulmonary disease (COPD) and bronchial asthma on therapeutic management and prognosis of patients with heart failure (HF). Methods Analysis of the information collected in a clinical registry of patients referred to a specialized HF unit from January-2010 to June-2012. Clinical profile, treatment and prognosis of patients was evaluated, according to the presence of COPD or asthma. Survival analyses were conducted by means of Kaplan-Meier and Cox's methods. Median follow-up was 1493 days. Results We studied 2577 patients, of which 251 (9.7%) presented COPD and 96 (3.7%) bronchial asthma. Significant differences among study groups were observed regarding to the prescription of beta-blockers (COPD=89.6%; asthma=87.5%; no bronchopathy=94.1%; P=.002) and SGLT2 inhibitors (COPD=35.1%; asthma=50%; no bronchopathy=38.3%; P=.036). Also, patients with bronchial disease received less frequently a defibrillator (COPD=20.3%; asthma=20.8%; no broncopathy=29%; P=.004). COPD was independently associated with increased risk of all-cause mortality (HR=1.64; 95%CI: 1.33-2.02), all-cause death or HF admission (HR=1.47; 95%CI: 1.22-1.76) and cardiovascular death or heart transplantation (HR=1.39; 95%CI: 1.08-1.79) as compared with patients with no bronchopathy. Bronchial asthma was not significantly associated with increased risk of adverse outcomes. Conclusions COPD, but not asthma, is an adverse independent prognostic factor in patients with HF. (AU)

ABSTRACT

INTRODUCTION: Both Parkinson's disease (PD) and the process of ageing are associated with functional limitations. The aim of this study was to determine the differences in motor and process skills between individuals with PD and healthy older adults, as well as to observe how disease progression affects motor and process skills performance in PD patients. SUBJECTS AND METHODS: A cross-sectional study was conducted. The Assessment of Motor and Process Skills (AMPS) measure was employed in order to analyze the differences in the motor and process skills of daily tasks in people with PD and healthy older adults age- and sex-matched. Part III of the Unified Parkinson Disease Rating Scale (UPDRS), the Hoehn and Yahr (HY) scale and the Schwab & England scale was administered to determine the severity of the disease. RESULTS: Seventy participants (49 patients with PD and 21 healthy older adults) were recruited for this study. Our results showed that even at moderate stages of the disease, both motor and process skills were found deteriorated in PD patients more than older healthy older adults (p < 0.001). As PD progresses, motor and process skills present significantly deterioration. CONCLUSION: PD leads to a greater deterioration in motor and process skills compared to healthy older adults. As disease stages advance according to the HY scale, performance in motor and process skills deteriorates significantly between moderate and advanced PD stages. According to the AMPS scale, PD patients show no impairment of processing skills up to HY IV, but motor impairment at HY stages II, III and IV.


TITLE: Habilidades motoras y de procesamiento en personas con enfermedad de Parkinson en comparación con adultos mayores sanos. Un estudio transversal.Introducción. Tanto la enfermedad de Parkinson (EP) como el proceso de envejecimiento están asociados con limitaciones funcionales. El objetivo de este estudio fue determinar las diferencias en habilidades motoras y de procesamiento entre individuos con EP y adultos mayores sanos, así como observar cómo la progresión de la enfermedad afecta al desempeño de las habilidades motoras y de procesamiento en pacientes con EP. Sujetos y métodos. Se realizó un estudio transversal. Se empleó la medida de la Assessment of Motor and Process Skills (AMPS) para analizar las diferencias en las habilidades motoras y de procesamiento de tareas cotidianas entre personas con EP y adultos mayores sanos, emparejados en edad y sexo. Se administró la sección III de la Unified Parkinson Disease Rating Scale, la escala de Hoehn y Yahr (HY) y la escala de Schwab & England para determinar la gravedad de la enfermedad. Resultados. Se reclutó a 70 participantes (49 pacientes con EP y 21 adultos mayores sanos). Nuestros resultados mostraron que incluso en estadios moderados de la enfermedad, tanto las habilidades motoras como las de procesamiento se encontraron deterioradas en los pacientes con EP en comparación con los adultos mayores sanos (p < 0,001). A medida que avanza la enfermedad, las habilidades motoras y de procesamiento presentan un deterioro significativo en las personas con EP. Conclusiones. La EP conduce a un mayor deterioro de las habilidades motoras y de procesamiento en comparación con adultos mayores sanos. A medida que avanzan los estadios de la enfermedad según la escala HY, el rendimiento en las habilidades motoras y de procesamiento se deteriora significativamente entre los estadios moderados y avanzados de la EP. Según la escala AMPS, los pacientes con EP no muestran un deterioro en las habilidades de procesamiento hasta el estadio HY IV, pero muestran deterioro motor en los estadios HY II, III y IV.

ABSTRACT

Introducción: La debilidad muscular en personas con enfermedad de Parkinson (EP) ha sido frecuentemente reconocida como un síntoma inespecífico. En otras patologías neurológicas, la debilidad de las extremidades inferiores, específicamente la debilidad de los cuádriceps, es el factor que causa mayor incapacidad para caminar. Pocas investigaciones han evaluado la relación entre la fuerza muscular de los miembros inferiores, utilizando herramientas objetivas en personas con EP y el desempeño de la marcha. El objetivo de este estudio fue analizar la correlación entre la fuerza muscular de los miembros inferiores, utilizando un dinamómetro isocinético, y los parámetros espaciotemporales de la marcha en la EP, en comparación con controles sanos emparejados por edad y sexo. Sujetos y métodos: El estudio se llevó a cabo con siete personas con EP –Hoehn y Yahr (HY) entre II y III– y siete controles sanos. Se realizaron pruebas isocinéticas de rodilla y tobillo a 60 y 120°/s y la prueba de marcha de 10 metros, a velocidad de marcha cómoda y rápida, en todos los sujetos reclutados. Resultados: Se observaron diferencias significativas en las medidas relacionadas con la fuerza de las extremidades inferiores y en los parámetros de la marcha entre las personas con EP y los controles. Los parámetros de la marcha mostraron excelentes correlaciones (rho = 0,7) para ambas extremidades inferiores: trabajo de flexión plantar de tobillo/desgaste corporal a 180°/s con número de pasos (indirecto) y zancada (directa) a ambas velocidades, y entre pico de torsión de flexión plantar de tobillo/desgaste corporal a 180°/s con número de pasos (indirecto) y zancada (directa) a velocidad máxima; y entre trabajo de extensión de rodilla/desgaste corporal a 60°/s con zancada (directa) a velocidad autoseleccionada. Conclusiones: La fuerza muscular de las extremidades inferiores de las personas con EP (estadios de HY II-III) se...(AU)


Introduction: Muscle weakness in persons with Parkinson disease (PD) has been frequently recognized as a nonspecific symptom. In other neurological conditions, lower limb weakness, specifically quadriceps weakness, is the factor that causes greater gait disability. Little research has evaluated the relationship between lower limb muscle strength, using objective tools, in PD persons and gait performance. The aim of this study was to analyze the correlation between lower limb muscle strength, using an isokinetic dynamometer, and the spatiotemporal gait parameters in PD, compared with age- and sex- matched healthy controls. Subjects and methods: The study was conducted with 7 persons with PD –Hoehn and Yahr (HY) between II-III– and 7 healthy controls. Isokinetic knee and ankle tests at 60 and 120°/s and the 10-meter walking test at comfortable and fast walking speed, were performed on all recruited subjects. Results: Significant differences in lower limb strength-related measures and gait parameters were observed between persons with PD and controls. Gait parameters showed excellent correlations (rho ≥ 0.7) for both lower limb: ankle plantar flexion work/body wearing at 180°/s with number of steps (indirect) and stride (direct) at both speeds, and between the ankle plantar flexion peak torque/ body wearing at 180°/s with number of steps (indirect) and stride (direct) at maximum speed; and between knee extension work/body wearing at 60°/s) with stride (direct) at self-selected speed. Conclusions: Persons with PD (HY II-III stages) lower limb muscle strength correlates excellently with gait pattern, showing lower isokinetic strength than healthy subjects of the same age and sex. This protocol showed safety to be performed in a larger sample.(AU)

ABSTRACT

Introducción: La progresión de la enfermedad de Parkinson (EP) da lugar a una pérdida de la capacidad para realizar actividades de la vida diaria y de la calidad de vida relacionada con la salud. Los objetivos de este estudio fueron establecer las relaciones entre las habilidades de desempeño ocupacional y la calidad de vida relacionada con la salud, y el grado de carga del cuidador en pacientes con EP. Pacientes y métodos: Participaron en el estudio 49 sujetos en diferentes estadios de EP según la escala de Hoehn y Yahr. Los pacientes fueron evaluados usando el cuestionario de la enfermedad de Parkinson (PDQ-39), el EuroQoL (EQ-5D), la evaluación de las habilidades motoras y de procesamiento (AMPS), y la entrevista de Zarit sobre la carga del cuidador (ZCBI). Resultados: Se encontraron fuertes correlaciones entre la sección de habilidades motoras de la AMPS y el PDQ-39 (r = –0,76; p = 0,001), y los cuestionarios EQ-5D (r = 0,72; p = 0,001), mientras que se encontraron correlaciones moderadas con las habilidades de procesamiento. Las habilidades de procesamiento de la AMPS se correlacionaron moderadamente con la movilidad y las actividades de la vida diaria. La ZCBI sólo se correlacionó débilmente con las habilidades motoras de la AMPS (r = –0,34; p = 0,02). Conclusión: Las puntuaciones decrecientes en la AMPS están estrechamente relacionadas con la pérdida de calidad de vida relacionada con la salud en pacientes con EP y, en menor medida, con el grado de carga del cuidador.(AU)


Introduction: The progression of Parkinson’s disease (PD) results in a loss of ability to performance activities of daily living and health-related quality of life. The objectives of this study were to establish the relations between occupational performance skills and health-related quality of life, and the degree of caregiver burden in PD patients. Patients and methods: Forty-nine patients at different stages of PD according to the Hoehn and Yahr scale participated in the study. Patients were assessed using the Parkinson’s Disease Questionnaire (PDQ-39), the EuroQoL (EQ-5D), the Assessment of Motor and Process Skills (AMPS), and the Zarit Caregiver Burden Interview (ZCBI). Results: Strong correlations were found between the motor skills section of the AMPS scale and the PDQ-39 (r = –0.76; p = 0.001), and the EQ-5D questionnaires (r = 0.72; p = 0.001), while moderate correlations were found with the process skills. AMPS process skills were moderately correlated with mobility and activities of daily living. The ZCBI was only weakly correlated with the AMPS motor skills (r = –0.34; p = 0.02). Conclusion: Declining scores on the AMPS scale are closely related to the loss of health-related quality of life in PD patients, and, to a lesser extent, with the degree of caregiver burden.(AU)

ABSTRACT

In this work, we develop experimentally a Fabry-Perot fiber optic interferometer applied to the measurement of autocorrelation of complex dynamic pulses generated by a figure-eight fiber laser. The principle is based in the superposition of multiple pulses, which requires two partially reflecting flat surfaces in parallel, resulting in a simple and compact autocorrelator design. The autocorrelation trace obtained exhibits a typical double-scaled structure for noise-like pulses (NLPs), with an ultrashort coherence spur on the order of 100 fs riding upon a broad pedestal of 120 ps. Finally, we show experimentally that the developed Fabry-Perot device is able to measure accurately the autocorrelation of NLPs, as confirmed by comparing the measurement with that of a conventional autocorrelator scheme based on a Michelson interferometer, with the additional advantages of a more compact setup and a much easier alignment procedure compared to the latter.

ABSTRACT

INTRODUCTION: Parkinson's disease (PD) affects the ability to perform activities of daily living (ADL), increasing with disease progression. The study of the association between PD severity and occupational performance skills may improve the understanding of the functional impairment associated with this pathology. OBJECTIVE: To study the relationship between PD severity and the loss of functional performance. PATIENTS AND METHODS: 49 non-demented PD patients were assessed with The Assessment of Motor and Process Skills (AMPS) scale, the Hoehn and Yahr scale (HY), the section III of the Unified Parkinson Disease Rating Scale (UPDRS), and the Schwab and England scale. RESULTS: PD severity was related to the AMPS scale (p < 0.001). There was a strong correlation between the AMPS motor skills and the HY scale (p < 0.001) and UPDRS III (p < 0.001), as well as between process skills and the Schwab and England E scale (p < 0.001). A moderate correlation was found between Schwab and England scale and AMPS motor skills, while a strong correlation was found with the process skills. Finally, a weak correlation was found between the AMPS scale and disease duration, yet only in the motor section. CONCLUSIONS: The severity of PD is closely related to the impairment of functional skills measured with the AMPS scale in non-demented PD patients. A strong correlation was found with the motor skills. A strong correlation was found between the AMPS process skills scale and Schwab and England ADL scale. A weak correlation was found between the AMPS motor scale and disease duration. The AMPS scale might be a useful tool to monitoring the PD progression through the observation of ADL performance.

Se encontró una correlación moderada entre la escala Schwab and England y las habilidades motoras de la AMPS, mientras que se encontró una correlación fuerte con las habilidades de procesamiento. Por último, se encontró una correlación débil entre la escala AMPS y los años de evolución de la EP, aunque sólo en el apartado motor. Conclusiones. La gravedad de la EP está estrechamente relacionada con el deterioro de las habilidades funcionales medidas con la escala AMPS en pacientes con EP no dementes. Se encontró una fuerte correlación con las habilidades motoras. Se encontró una fuerte correlación entre la escala AMPS de habilidades de procesamiento y la escala Schwab and England. Se encontró una correlación débil entre la escala motora AMPS y la duración de la enfermedad. La escala AMPS podría ser una herramienta útil para monitorizar la progresión de la EP a través de la observación del desempeño de las AVD.

Conclusions: The severity of PD is closely related to the impairment of functional skills measured with the AMPS scale in non-demented PD patients. A strong correlation was found with the motor skills. A strong correlation was found between the AMPS process skills scale and Schwab & England ADL scale. A weak correlation was found between the AMPS motor scale and disease duration. The AMPS scale might be a useful tool to monitoring the PD progression through the observation of ADL performance.(AU)

ABSTRACT

OBJECTIVE: Assessment of neurobehavior and visual function of newborns with congenital heart disease during the post-operative period to identify infants at risk of neurodevelopmental and visual impairment. STUDY DESIGN: Prospective study that included 45 newborns who underwent cardiac surgery. Newborn Behavioral Observations test (NBO) and "ML Battery of Optotypes" were used for assessment. RESULTS: The median NBO global score was 2.4 [2.1-2.6]. Total days of oral morphine [p = 0.005] and total days of sedation [p = 0.009] were strongly related to abnormal evaluations. Time of cerebral regional oxygen saturation (CrSO2) under 40% during surgery and increased lactate were related to abnormal motor evaluation. Only 14.5% of patients presented pathological results in visual evaluation. CONCLUSIONS: We have demonstrated alterations in attention, autonomic, motor, and oral motor function. Duration of sedative medication, time of CrSO2 under 40% during surgery, and increased lactate are the most important risk factors. No significant visual impairment was detected.

ABSTRACT

Título abreviado: Se exponen los recursos asistenciales del Sistema Sanitario Público de Andalucía relacionados con el diagnóstico, tratamiento y seguimiento de los pacientes con apnea obstructiva del sueño. Igualmente se describen propuestas para una optimización en el manejo de esta entidad enfatizando la necesidad de recursos y colaboración entre diferentes niveles asistenciales. Objetivo: Determinar en el Sistema Sanitario Público de Andalucía (SSPA) los recursos actuales en la apnea obstructiva del sueño (AOS) e identificar propuestas de mejora. Método: Estudio transversal, basado en encuestas realizadas en 49 hospitales del SSPA. Se registraron variables relacionadas al diagnóstico, tratamiento y seguimiento de la AOS, distinguiendo entre centros que realizaban polisomnografía y los que no. Incluimos un apartado sobre propuestas de mejora. Resultados: Un 97% de los centros realizan poligrafía y un 29% polisomnografía, y sólo el 39,5% disponen de consulta específica. La demora diagnóstica para la poligrafía es de 169 ± 163,4 días y para la polisomnografía de 173 ± 152,5 días. Se realizan un total de 1.113 ± 1.004,6 pruebas por 100.000 habitantes y año, de ellas 235 ± 166,2 son poligrafías diagnósticas. La presión eficaz se titula en un 49% con auto-CPAP y el control terapéutico lo realiza frecuentemente la empresa suministradora (77%). Entre las propuestas de mejora, destacan la falta de un protocolo de derivación y coordinación entre diferentes niveles asistenciales (90% de los encuestados), y la demora diagnóstica, atribuible en un 63% de los casos al déficit de recursos físicos y de personal. Conclusión: El número de pruebas diagnósticas aún son insuficientes y la demora diagnóstica es excesiva. Sobre todo, en el control terapéutico la empresa suministradora tiene un papel relevante. Se propone la realización de protocolos entre diferentes unidades asistenciales y aumentar los recursos actuales. (AU)


Short title: The healthcare resources of the Andalusian Public Health System related to the diagnosis, treatment and follow-up of patients with obstructive sleep apnea are presented. Proposals for optimizing the management of this entity are also described, emphasizing the need for resources and collaboration between different levels of care. Objective: Determine the current resources in the Public Health System of Andalusia (SSPA) in obstructive sleep apnea (OSA) and identify proposals for improvement. Method: Cross-sectional study, based on surveys conducted in 49 SSPA hospitals. Variables related to the diagnosis, treatment, and follow-up of OSA were recorded, distinguishing between centers that performed polysomnography and those that did not. We include a section on proposals for improvement. Results: 97% of the centers perform polygraphy and 29% polysomnography, and only 39.5% have a specific consultation. The diagnostic delay for polygraphy is 169 ± 163.4 days and for polysomnography 173 ± 152.5 days. A total of 1,113 ± 1,004.6 tests are performed per 100,000 inhabitants per year, of which 235 ± 166.2 are diagnostic polygraphs. The effective pressure is titrated in 49% with auto-CPAP and therapeutic control is frequently carried out by the supplying company (77%). Among the proposals for improvement, the lack of a protocol for referral and coordination between different levels of care (90% of those surveyed), and the diagnostic delay, attributable in 63% of cases to the lack of physical and personnel resources, stand out. Conclusion: The number of diagnostic tests are still insufficient and the diagnostic delay is excessive. Above all, in therapeutic control, the supplier company has a relevant role. It is proposed to carry out protocols between different care units and increase current resources

ABSTRACT

Los elementos de protección personal (EPP) son el conjunto de equipamiento, componente de las precauciones estándares, destinados a proteger la piel y mucosas del operador evitando el contacto con agentes infecciosos. Los funcionarios de salud que tratan con pacientes COVID-19 se encuentran más expuestos a infectarse en comparación con el resto de los funcionarios de salud, razón por la cual deben utilizar de manera adecuada estos elementos de protección, para protegerse de una posible infección por COVID-19. El objetivo del estudio es deter-minar disponibilidad, manejo y uso EPP utilizados por los funcionarios del Servicio de Urgencia del Complejo Asistencial Barros Luco Trudeau. Este es un estudio transversal descriptivo realizado por medio de encuesta a los funcionarios de la Unidad de Emergencia HBLT a través de Google Forms®. Del total de funcionarios de la Unidad de Emergencia del Hospital Barros Luco Trudeau, un total de 123 funcionarios realizaron la encuesta cumpliendo con los criterios de inclusión, de los cuales 78 fueron mujeres y 45 hombres, con edades dentro del rango desde los 20 años a mayores de 61 años. Se observó que 39,0% de los funcionarios fue notificado como COVID-19 positivo. Un 60,2% de los funciona-rios tuvo una secuencia predeterminada para instalación de los EPP y un 68,3% para el retiro de los EPP. Los más utilizados fueron mascarillas quirúrgicas (95,9%), mascarilla KN 95 (88,6%) y guantes (90,2%). Este estudio contribuye a destacar la importancia en la correcta utilización de los EPP por parte de los funcionarios de la salud, para limitar los contagios y mejorar el cuidado de los equipos de salud durante la pandemia de COVID-19. Además, se describir un patrón de sintomatología más frecuente en los profesionales sanitarios del servicio de urgencia.


Personal protective equipment (PPE) is a set of equipment, a component of the standard precautions, intended to protect the skin and mucous membranes of the operator avoiding contact with infectious agents. Healthcare workers who deal with COVID-19 patients are at higher risk of being infected compared to other health professionals. Thus they must use them appropriately to protect themselves from possible COVID-19 infection. This study aimed to determine the presence, handling, and use of PPE by the personnel of the Emergency Service of the Barros Luco Trudeau Department. This descriptive cross-sectional study was carried out applying a survey to the staff of the HBLT Emergency Unit through the Google Forms® platform. A total of 123 staff of the Emergency Unit of the Barros Luco Trudeau Hospital that answered the survey met the inclusion criteria. Seventy-eight of them were women and 45 men, within the range of 20 to over 61 years old. Thirty-nine per cent of the personnel were notified as COVID-19 positive. Regarding PPE use, 60,2% of the personnel had a predetermined sequence for installation, and 68.3% had a correct sequence for removal of the PPE. The most used were surgical masks (95.9%), KN 95 masks (88.6%) and gloves (90.2%). Of those COVID-19 positive 46.3% were asymptomatic, and of those who had symptoms the most prevalent ones were headache (41.5%), tiredness (34.1%) and odynophagia (31.7%). This study highlights the im-portance of using the personal protective elements by health staff as self-care during the COVID-19 pandemic, in addition to describing the most frequent pattern of symptoms in health professionals in the emergency department.

ABSTRACT

An experimental study of the interaction between a Mylar® polymer film and a multimode fiber-optic is presented for the simultaneous fiber-optic detection of low-pressure and liquid levels. The junction between the polymer and optical fiber produces an interference spectrum with maximal visibility and free spectral range around 9 dB and 31 nm, respectively. Water pressure, which is controlled by the liquid level, stresses the polymer. As a result, the spectrum wavelength shifts to the blue region, achieving high sensitivities around 2.49 nm/kPa and 24.5 nm/m. The polymeric membrane was analyzed using a finite element model; according to the results, the polymer shows linear stress response. Furthermore, the membrane material is operated below the yielding point. Moreover, the finite analysis provides information about the stress effect over the thickness and the birefringence changes. This sensor exhibits a quadratic polynomial fitting with an adjusted R-squared of 0.9539. The proposed sensing setup offers a cost-effective alternative for liquid level and low-pressure detection.

ABSTRACT

The pursuit of firmer and better-quality blueberries is a continuous task that aims at a more profitable production. To this end it is essential to understand the biological processes linked to fruit firmness, which may diverge among tissues. By contrasting varieties with opposing firmness, we were able to elucidate events that, taking place at immature stage, lay the foundation to produce a firmer ripe fruit. A deep analysis of blueberry skin was carried out, involving diverse comparative approaches including proteomics and metabolomics coupled to immunolocalization assays. In'O'Neal' (low firmness) enhanced levels of aquaporins, expansins and pectin esterases at the green stage were found to be critical in distinguishing it from 'Emerald' (high firmness). The latter featured higher levels of ABA, low methyl esterified pectins in tricellular junctions and high levels of catechin at this stage. Meanwhile, in 'Emerald' 's ripe fruit epicarp, several mechanisms of cell wall reinforcement such as calcium and probably boron bridges, appear to be more prominent than in 'O'Neal'. This study highlights the importance of cell wall reorganization and structure, abundance of specific metabolites, water status, and hormonal signalling in connection to fruit firmness. These findings result particularly valuable in order to improve the fertilization procedures or in the search of molecular markers related with firmness.

ABSTRACT

RESUMEN: El Trauma Maxilofacial (TMF) es una patología que presenta alta frecuencia en la actualidad, constituyendo un problema global de salud para los centros de alta complejidad y los equipos multidisciplinarios involucrados en su manejo y resolución. (neurología, maxilofacial, otorrinolaringología, oftalmología). Su etiología y epidemiología varía significativamente en la literatura. El objetivo de este estudio es caracterizar a los pacientes atendidos en un hospital del s ector sur de Santiago, Chile, identificando sus factores sociales y clínicos, clasificando los principales tipos de fractura a nivel de tercio medio facial. Se realizó un estudio observacional retrospectivo con los Datos de Atención de Urgencia (DAU) de los pacientes atendidos en el Servicio Dental de la Unidad de Emergencia del Complejo Asistencial Barros Luco (CABL), analizando el sexo, edad, comuna de procedencia, etiología del trauma, categorización según el "Emergency Severity Index", horario de ingreso y evaluación, estructuras óseas comprometidas de los pacientes con diagnóstico final de Fractura en Tercio Medio Facial. Se utilizaron estimadores puntuales de porcentaje, media y desviación estándar para representar las variables. Se calculó la significancia de relación de variables independientes, con valor de p < 0,05 estadísticamente significativo por el tamaño muestral. Población principalmente afectada corresponden a hombres versus mujeres (2.4:1), y entre segunda y tercera década de vida. Principal etiología identificada fue accidentes en el hogar (n = 73), seguidos de agresiones (n = 55). La mayoría de los pacientes ingresan con un riesgo C4 (n = 107) y C3 (n = 64). Fractura más frecuentemente es la nasal (46 %), seguidas de complejo orbitario (11.3 %) y arco cigomático (7.9 %). Es necesario mantener actualizada la epidemiología del TMF considerando la complejidad de su manejo temprano, morbilidades al mediano y largo plazo, con el objetivo de tener un rol activo en su prevención y tratamiento.


ABSTRACT: Maxillofacial Trauma (TMF) is a frequent pathology nowadays and presents a global health problem for specialized trauma centers and the multidisciplinary teams involved in its management and treatment (neurology, maxillofacial, otolaryngology, ophthalmology). The objective of this study is to characterize the patients seen in a hospital in the southern sector of Santiago, Chile, identifying their social and clinical factors, classifying the main types of fracture at the level of the facial third middle. A retrospective observational study was conducted with the Emergency Care Data (DAU) of the patients attended in the Dental Service of the Emergency Unit of the Barros Luco Assistance Complex (CABL), extracting the sex, age, commune of Origin, etiology of the trauma, categorization according to the "Emergency Severity Index" evaluation time and compromised bone structures of patients with diagnosis of Fracture in the Third Facial Mid-Section. Point estimators of percentage, mean and standard deviation were used to represent the variables. The significance of the relationship of independent variables was calculated, with a value of p <0.05 statistically significant for the sample size. Mainly affected population corresponded to men versus women (2.4: 1), and between the second and third decade of life. Main etiology identified were accidents at home (n = 33), followed by assaults (n = 55). Most of the patients entered with a risk of C4 (n = 107) and C3 (n = 64). The most frequent fracture was nasal (46%), followed by an orbital complex (11.3 %) and a zygomatic arch (7.9 %). It is necessary to keep the epidemiology of TMF up to date considering the complexity of its early management and morbidities in the medium and long term.

ABSTRACT

The identification of the heart rhythm during an episode of transient loss of consciousness (TLOC) is considered the reference standard method to elucidate the underlying aetiology. This study aimed to characterise heart rhythm in dogs during TLOC using Holter and external loop recorder monitoring. We retrospectively reviewed 24-h Holter monitoring and external loop recorder tracings from 8084 dogs. Heart rhythms from dogs that experienced TLOC during the recording was analysed to identify rhythm disturbances that occurred during episodes of TLOC. Electrocardiograms (ECGs) were subsequently categorised into Type 1 (ventricular arrest), Type 2 (sinus bradycardia), Type 3 (no/slight rhythm variations), and Type 4 (tachycardia). Transient LOC was documented in 92 dogs over 230 episodes of TLOC. Percentage of cases with ECGs compatible with each classification were as follows: 72.1%, Type 1; 6.1%, Type 2; 20.9%, Type 3; and 0.9%, Type 4. Cardiac rhythm during the TLOC could have been a consequence of a neurocardiogenic mechanism in 46.7% cases, while intrinsic rhythm disturbances of the sinus node or of the atrioventricular node were diagnosed in 31.5% cases. In two cases, tachycardia was the possible cause of the TLOC. ECG patterns in dogs presenting with multiple TLOC episodes were completely reproducible during each episode. TLOC in dogs was primarily caused by ventricular arrest. Most dogs with TLOC had electrocardiographic finding suggestive of a reflex or neurally-mediated syncope, but one third had an ECG more suggestive of a conduction disorder. Distinguishing these two entities could help inform diagnostic, therapeutic, and prognostic plans.
