Objetivo: Determinar la efectividad de 5-Fluorouracilo intralesional en el alivio sintomático, astigmatismo y deseo de cirugía en pacientes con pterigión primario. Métodos: Estudio experimental realizado entre enero y marzo de 2020 en la Unidad de Oftalmología del Hospital del Salvador, Chile. Se seleccionaron 14 ojos (14 pacientes) en lista de espera quirúrgica, expuestos a inyecciones intralesionales quincenales de 10 mg de 5-FU. Se realizó una evaluación clínica inicial con OSDI para medición sintomática, cámara fotográfica y lámpara de hendidura para apariencia clínica, y autorrefractómetro para astigmatismo, siendo reevaluados 60 días después, añadiéndose la pregunta de si mantenían el deseo de operarse. Se dividió la muestra en grupo A y B según recibieron dos o una dosis de 5-FU, respectivamente. Resultados: La edad promedio de los participantes fue 56,8 ± 11,1 años. El grupo A presentó un OSDI inicial de 50 ± 23,8 que, posterior a la intervención, se redujo a 21 ± 13,5 (p < 0,001). El grupo B tuvo un OSDI inicial de 47 ± 17,3, disminuyendo a 22 ± 16,2 (p < 0,005). Ambos cambios estadísticamente significativos. En cuanto al aspecto físico, hubo reducción del tamaño lesional en 2 de los 14 pacientes, ambos del grupo A. No hubo cambios respecto al grado de astigmatismo. Hubo 2 pacientes que decidieron no realizarse la cirugía posterior a la intervención. Conclusión: La inyección intralesional de 5-FU demostró mejoría significativa en el alivio sintomático, sin complicaciones asociadas, generando un tratamiento alternativo al quirúrgico en pacientes con pterigión primario, pudiendo posponer la cirugía.

Objectives: To determine the effectiveness of intralesional 5-Fluorouracil (5-FU) in symptomatic relief, astigmatism, and desire for surgery in patients with primary pterygium. Methods: The experimental study was carried out between January and March 2020 in the Ophthalmology Unit of the Hospital del Salvador, Chile. Fourteen eyes (14 patients) were selected on the surgical waiting list and exposed to fortnightly intralesional injections of 10 mg of 5-FU. An initial evaluation was performed with OSDI for symptomatic measurement, a photographic camera and slit lamp for clinical appearance, and an auto-refractometer for astigmatism, being re-evaluated 60 days later, adding the question of whether they maintained the desire to undergo surgery. The sample was divided into groups A and B depending on whether they received two or one dose of 5-FU, respectively. Results: The average age of the participants was 56.8 ± 11.1 years. Group A presented an initial OSDI of 50 ± 23.8, which, after the intervention, decreased to 21 ± 13.5 (p < 0.001). Group B had an initial OSDI of 47 ± 17.3, decreasing to 22 ± 16.2 (p < 0.005)-statistically significant changes. The degree of astigmatism had no changes. Regarding the physical aspect, there was a reduction in the size of the lesion in 2 of the 14 patients, both in group A. Two patients decided not to undergo surgery after the intervention. Conclusions: The intralesional injection of 5-FU showed a significant improvement in symptomatic relief without associated complications, generating a therapeutic alternative in patients with primary pterygium without surgical indication.

CFD Study of a Tunnel-Ventilated Compost-Bedded Pack Barn Integrating an Evaporative Pad Cooling System.

Evaporative cooling is one of the most efficient techniques to reduce heat stress in cows in agricultural facilities. Additionally, compost-bedded pack barn has been shown to improve the welfare and production of cows. Two techniques were combined and analysed by developing a computational fluid dynamics (CFD) model of a tunnel-ventilated compost-bedded packed barn that integrated the heat and airflow dynamics of an evaporative pad cooling system. This allowed us to study the distribution of dry-bulb temperature, relative humidity and airflow velocity inside the barn based on the external environmental conditions, thickness of the pad, water temperature and specific manufacturer characteristics of the pad, providing optimal cooling pad location, size and operating conditions in the barn. Employing experimental data the CFD model was validated showing good agreement. The Equivalent Temperature Index for dairy Cattle (ETIC) was used to determine the level of stress of the cows considering the airflow velocity. It was found a moderate stress due to high relative humidity and low airflow velocity. From the predicted results, it was recommended to increase the airflow velocity above 3 m s-1 when simultaneously the external dry-bulb temperature and relative humidity exceed 30 °C and 55%, respectively, simultaneously. Additionally, installation of baffles at the pad outlet to drive the airflow to the floor was suggested to improve the drying of the compost-bedded closed to the pads, where a low airflow velocity region was established.

Pre-Anthesis Cytokinin Applications Increase Table Grape Berry Firmness by Modulating Cell Wall Polysaccharides.

The use of plant growth regulators (PGRs) is widespread in commercial table grape vineyards. The synthetic cytokinin CPPU is a PGR that is extensively used to obtain higher quality grapes. However, the effect of CPPU on berry firmness is not clear. The current study investigated the effects of pre-anthesis applications (BBCH15 and BBCH55 stages) of CPPU on 'Thompson Seedless' berry firmness at harvest through a combination of cytological, morphological, and biochemical analyses. Ovaries in CPPU-treated plants presented morphological changes related to cell division and cell wall modification at the anthesis stage (BBCH65). Moreover, immunofluorescence analysis with monoclonal antibodies 2F4 and LM15 against pectin and xyloglucan demonstrated that CPPU treatment resulted in cell wall modifications at anthesis. These early changes have major repercussions regarding the hemicellulose and pectin cell wall composition of mature fruits, and are associated with increased calcium content and a higher berry firmness at harvest.

Assessment of spatial variability of bedding variables in compost bedded pack barns with climate control system.

The aim of this research was to evaluate the spatial distribution of bedding variables in a climate-controlled compost bedded pack barn (CBP) equipped with an evaporative cooling system associated with a tunnel ventilation mode. The study was conducted on a farm in the West Mesoregion of Minas, MG, Brazil. The interior of the animal facility was divided into a mesh of 120 equidistant points, where the bedding surface temperature (tb-sur), the bedding temperature at 0.20 m depth (tb-20) and the bedding penetration resistance (PRb) of layer 0 to 0.20 m depth were measured. Bedding samples were collected to obtain the moisture (Mb) and pH in the surface and at 0.20 m depth. Geostatistics technique was used to evaluate the dependence and spatial distribution. Through the bedding area, the tb-sur presented low variability, with 6 ºC of amplitude, and tb-20 presented highest values (up to 55 °C). The spatial distribution of Mb-20 was similar to that observed on the surface and its highest levels occurred in the region near the feed alley (> 40%). The distribution of pH was similar in both layers. The tendency of high PRb occurred in the layer between 0.15 and 0.20 m (0 and 1500 kPa).

Trauma quality indicators: internationally approved core factors for trauma management quality evaluation.

INTRODUCTION: Quality in medical care must be measured in order to be improved. Trauma management is part of health care, and by definition, it must be checked constantly. The only way to measure quality and outcomes is to systematically accrue data and analyze them. MATERIAL AND METHODS: A systematic revision of the literature about quality indicators in trauma associated to an international consensus conference RESULTS: An internationally approved base core set of 82 trauma quality indicators was obtained: Indicators were divided into 6 fields: prevention, structure, process, outcome, post-traumatic management, and society integrational effects. CONCLUSION: Present trauma quality indicator core set represents the result of an international effort aiming to provide a useful tool in quality evaluation and improvement. Further improvement may only be possible through international trauma registry development. This will allow for huge international data accrual permitting to evaluate results and compare outcomes.

[Hospitales del Instituto Mexicano del Seguro Social durante los sismos de septiembre de 2017. Análisis desde la perspectiva del Programa Hospital Seguro].

INTRODUCTION: The function of hospitals during major emergency or disaster is vital. Their response capacity depends on their geographic location, adequate organization, structural safety and safety of non-structural elements. After September 2017 earthquakes, self-assessment and Safe Hospital Program assessment results were compared in disabled hospitals belonging to the Mexican Institute of Social Security. OBJECTIVE: To compare the Hospital Safety Index (HIS) with self-assessments carried out by the units. METHOD: HIS and the Pan-American Health Organization/World Health Organization checklist were used. The comparison was carried out in 3 hospitals that were disabled after September 2017 earthquakes. RESULTS: Variability was observed in HIS, which revealed self-assessment biases: no hospital obtained a HIS score lower than 0.35, although all 3 were disabled in the immediate phase after the seismic events. CONCLUSIONS: Result variability depends on who applies the instrument. Quick HIS assessment provides an immediate idea of the probability for a hospital to continue functioning in case of disaster and allows determining mitigation actions to increase health facilities' resilience and safety.

INTRODUCCIÓN: La función de los hospitales durante una emergencia mayor o desastre es vital. Su capacidad de respuesta depende de su ubicación geográfica, adecuada organización, seguridad estructural y seguridad de elementos no estructurales. Después de los sismos de septiembre de 2017 se compararon los resultados de las autoevaluaciones y la evaluación del Programa Hospital Seguro en los hospitales inhabilitados pertenecientes al Instituto Mexicano del Seguro Social. OBJETIVO: Comparar el Índice de Seguridad Hospitalaria (ISH) contra las autoevaluaciones realizadas por las unidades. MÉTODO: Se utilizó el ISH y la Lista de Verificación de la Organización Panamericana de la Salud/Organización Mundial de la Salud. La comparación se realizó en tres hospitales inhabilitados posterior a los sismos de septiembre de 2017. RESULTADOS: Se observó variabilidad en los ISH, lo que evidenció sesgos en la autoevaluación: ningún hospital obtuvo una calificación inferior a 0.35 en su ISH aunque tres quedaron inhabilitados en la fase inmediata posterior a los eventos sísmicos. CONCLUSIONES: La variabilidad en los resultados depende de quien aplica el instrumento. La evaluación rápida con ISH proporciona una idea inmediata de la probabilidad de que un hospital continúe funcionando en caso de desastre y permite determinar las acciones de mitigación para incrementar la resiliencia y seguridad de las instalaciones de salud.

Experiencia de un equipo médico de emergencia del IMSS durante el sismo en México en setiembre de 2017

[RESUMEN]. El objetivo de este trabajo es describir las acciones desarrolladas por el equipo médico de emergencia (EMT por sus siglas en inglés) del Instituto Mexicano del Seguro Social (IMSS) durante la emergencia derivada del sismo del 7 de setiembre de 2017, el cual tuvo una magnitud de 8,2 grados con epicentro a 133 km al suroeste de Pijijiapan, Chiapas, México. Una vez realizada la evaluación inicial intersectorial de la emergencia, se activó el sector salud. Dentro de esta respuesta, y una vez determinado un número elevado de lesionados y un riesgo alto para la salud pública de la población afectada, el IMSS desplegó en la región un EMT capacitado y entrenado para apoyar en la respuesta de atención médica y quirúrgica de lesionados. Las acciones del EMT, conformado por especialistas en urgencias médico-quirúrgicas y desastres, incluyeron la atención médica de 252 pacientes, la gestión del traslado de 57 pacientes y la colaboración en la habilitación de un hospital provisorio. Para mejorar la respuesta en situaciones de desastres, se requiere seguir el proceso de integración, registro y capacitación de los EMT a nivel nacional e internacional.

[ABSTRACT]. The objective of this article is to describe the actions undertaken by the emergency medical team (EMT) of the Mexican Social Security Institute (MSSI) during the emergency caused by the earthquake of September 7, 2017 (magnitude 8.2; epicenter 133 km southwest of Pijijiapan, Chiapas, Mexico). After the initial intersectoral assessment of the emergency had been conducted, the health sector stepped in. As part of this response effort, and once it was determined that a large number of people had been injured and that the health risks facing the affected population were substantial, the MSSI deployed an EMT equipped and trained to provide support in the medical and surgical treatment of injured people. The actions of the EMT, composed of specialists in medical and surgical emergencies and disaster situations, included providing medical care to 252 patients, managing the transfer of 57 patients, and helping to set up an emergency hospital. To improve response efforts during disaster situations, it is necessary to follow the process of forming, registering, and training EMTs at the national and international levels.

O propósito deste artigo é descrever as ações empreendidas pela equipe médica de emergência (EMT) do Instituto Mexicano de Seguro Social (IMSS, instituição pública que presta serviços de saúde) na crise de emergência causada pelo terremoto de 7 de setembro de 2017, com magnitude de 8,2 graus e epicentro a 133 km a sudoeste de Pijijiapan, Chiapas, México. Após a avaliação intersetorial inicial de emergência, o setor da saúde foi ativado. Como parte da resposta, diante do elevado número de feridos e alto risco para a saúde pública da população afetada, o IMSS mobilizou uma EMT na região, capacitada e treinada para dar apoio à resposta de atendimento médica e cirúrgica das vítimas. A EMT, formada por especialistas em emergências médico-cirúrgicas e desastres, prestou atendimento médico a 252 pacientes, coordenou a transferência de 57 pacientes e também colaborou na preparação de um hospital provisório. A fim de melhorar a resposta a desastres, é necessário prosseguir com o processo de integração, cadastramento e capacitação das EMT ao nível nacional e internacional.
