Targeted temperature management (TTM) has been partially applied in patients with restoration of spontaneous circulation (ROSC) after cardiac arrest (CA). In the 2020 American Heart Association (AHA) cardiopulmonary resuscitation (CPR) guidelines, TTM is used as advanced life support after ROSC for the treatment of patients with CPR. TTM has a protective effect on cardiac function after CA, but the specific mechanism of its protective effect on cardiac function remains unclear. In this paper, the basic experimental progress, clinical trial progress and development prospect of TTM on the protective mechanism of cardiac function after CA are reviewed.

Mild hypothermia, as a common means of intraoperative nerve protection, has been used in clinical practice. Compared with the traditional methods such as freezing helmet and nasopharyngeal cooling, hypothermic blood perfusion is considered to be a promising treatment for mild hypothermia, but it lacks experimental and theoretical verification of its cooling effect. In this study, the commercial finite element simulation software COMSOL combined the Pennes equation with the cerebrovascular network model to construct a new simplified human brain model, which was further used to simulate the cooling process of cerebral hypothermic blood perfusion. When the hypothermic blood perfusion was 33 ℃, the human brain could enter the mild hypothermic state within 4 minutes. By comparing with helmet cooling, the feasibility and efficiency of the blood perfusion scheme were verified. By comparing with the calculation results based on Pennes equation, the rationality of the model constructed in this study were verified. This model can non-intrusively predict the changes of brain temperature during surgery, and provide a reference for the setting of treatment parameters such as blood temperature, so as to provide personalized realization of safer and more effective mild hypothermia neuro protection.

Community-acquired pneumonia is recognized as one of the main infectious health problems worldwide. The objective was to determine the condition of predictors of death for a group of selected clinical conditions, and for laboratory variables frequently used in practice. Study with descriptive design, which included 967 patients with pneumonia hospitalized between 2016 and 2019, and whose information was obtained from clinical records. Statistical treatment included bivariate and multivariate analysis (logistic regression); it was used the ratio of crossed products (odds ratio) and its 95% confidence interval. Several manifestations were significantly more frequent in older adults: dyspnea (OR 1.5[1.07,2.1]), absence of productive cough (OR 1.7 [1.3, 2.4]), neuropsychological manifestations (OR 2 [1.4,2.8]), tachypnea (OR 1.5 [1.1,2.1]), arterial hypotension (OR 2.1 [1.2,3.6]), anemia (OR 1.6[1.2,2.2]), elevated creatinine (OR 1.6[1.2,2.3]) and hypoproteinemia (OR 3.3[1.9,5.7]); showed a significant association with death: absence of productive cough, neuropsychological manifestations, temperature below 36 degrees Celsius, blood pressure below 110/70 mmHg, respiratory rate above 20 per minute, hemoglobin below 100 g/L, erythrosedimentation greater than 20 mm/L, leukopenia less than 5 x 109/L and serum creatinine above 130 micromol/L. As conclusions certain clinical and laboratory conditions present in the patient at the time of hospital admission, of routine exploration in the comprehensive assessment of the patient, were predictors of death. Additionally, the existence of evident differences in the number of conditions with a predictive nature of death between the population with pneumonia under 60 years of age and the elderly, as well as in the frequency of these conditions in both subgroups, is verified.

La neumonía adquirida en la comunidad está reconocida como uno de los principales problemas de salud de tipo infeccioso al nivel mundial. La investigación tuvo como objetivo determinar el carácter de predictores de fallecimiento de un grupo de condiciones clínicas seleccionadas, y de variables de laboratorio de uso frecuente en la práctica. Se realizó un estudio con diseño descriptivo, que incluyó a 967 pacientes con neumonía hospitalizados entre 2016 y 2019, y cuya información se obtuvo de los expedientes clínicos. El tratamiento estadístico incluyó análisis bivariante y multivariado (regresión logística); como estadígrafo se utilizó la razón de productos cruzados (odds ratio) y su intervalo de confianza de 95%. Entre los resultados se destacan los siguientes: varias manifestaciones fueron significativamente más frecuentes en los adultos mayores: disnea (OR 1,5[1,07;2,1]), ausencia de tos productiva (OR 1,7[1,3;2,4]), manifestaciones neuropsicológicas (OR 2[1,4;2,8]), taquipnea (OR 1,5[1,1;2,1]), hipotensión arterial (OR 2,1[1,2;3,6]), anemia (OR 1,6[1,2;2,2]), creatinina elevada (OR 1,6[1,2;2,3]) e hipoproteinemia (OR 3,3[1,9;5,7]); mostraron asociación significativa con el fallecimiento: ausencia de tos productiva, manifestaciones neuropsicológicas, temperatura por debajo de 36 grados Celsius, tensión arterial inferior a 110/70 mmHg, frecuencia respiratoria por encima de 20 por minuto, hemoglobina inferior a 100 g/L, velocidad de sedimentación eritrocitaria superior a 20 mm/L, leucopenia inferior a 5 x 109/L y creatinina sérica por encima de 130 micromol/L. Se concluye que ciertas condiciones clínicas y de laboratorio presentes en el paciente al momento del ingreso hospitalario, de exploración habitual en la valoración integral del enfermo, constituyeron predictores de fallecimiento. Adicionalmente, se comprueba la existencia de evidentes diferencias en el número de condiciones con carácter predictor de muerte entre la población con neumonía menor de 60 años y los adultos mayores, así como en la frecuencia de estas condiciones en ambos subgrupos.

OBJECTIVES@#To study the cooling reaction kinetic characteristics of the temperature difference between cadaver temperature and ambient temperature (hereinafter referred to as "cadaver temperature difference") according to the reaction kinetics method.@*METHODS@#Thirty rabbits were randomly divided into 5 groups with 6 rabbits in each group. The rabbits were injected with 10% potassium chloride solution intravenously. After death, the rabbits were placed at 5 ℃, 10 ℃, 15 ℃, 20 ℃ and 25 ℃ environment condition, respectively, and the rectal temperature was measured every minute for 20 hours. The measured cadaver temperature was subtracted from ambient temperature, and the cadaver temperature difference data was calculated using the reaction kinetics formula. The linear regression equation was fitted for analysis, and the experimental results were applied to the temperature difference data of human body after death for verification.@*RESULTS@#Under different environmental conditions, the linear coefficient determination of temperature difference -ln(C/C0) in rabbits was 0.99, showing a good linear relationship with time t. The application of human body temperature data after death was consistent with the results of animal experiments.@*CONCLUSIONS@#Under stable conditions, the temperature difference cooling process after death in rabbits is a first-order kinetic response. The method can also be used to study the temperature difference in human body after death.

Body temperature is an important physiological parameter of the human body and is used in medicine to reflect the physiological state and health status of the human body. At present, the commonly used clinical thermometers on the market are mainly divided into contact and non-contact types. Most of them are used for rapid body temperature measurement, and it is not easy to monitor body temperature changes in real time. This article introduces a new wearable wireless body temperature monitoring system based on NTC, which senses through NTC. The temperature changes are amplified and filtered, zeroed, and calibrated, and then the temperature data is uploaded to the mobile phone APP via Bluetooth in real time to achieve real-time accurate measurement of body temperature.

Objective: To investigate the effect of room and body temperatures on cyclic fatigue resistance of three endodontic nickel-titanium rotary files: Hyflex EDM (HEDM) (Coltene/Whaledent, Switzerland), WaveOne Gold (WOG) (Dentsply Maillefer, Switzer), and EdgeOne Fire (EOF) (EdgeEndo, Albuquerque, New Mexico, USA) in a double- curved canal. Material and Methods: In this study, Sixty NiTi rotary files were used. These files were divided into three groups (n = 20 for each group). Group A: HEDM (size 25, taper 0.08), group B: WOG (size 25, taper 0.07), and group C: EOF (size 25, taper 0.07). Each group was subdivided into two subgroups (n=10 for each subgroup). One of the subgroup was subjected to cyclic fatigue test at room temperature (20±1°C), while the other subgroup was subjected to cyclic fatigue test at body temperature (37±1°C). These files were tested by using a custom-made artificial canal with a double curvature (coronal curve: 60° curvature with 5 mm radius; apical curve: 70° curvature with 2 mm radius). All instruments were rotated according to the manufacturer instructions until the fracture occurred by using electric endodontic motor (Wave One, Dentsply Maillefer, Ballaigues, Switzerland). The number of cycles to fracture (NCF) and the fractured fragment length (FL) were recorded for each endodontic file. The data were gathered and statistically analyzed using shapiro-wilk test and two-way ANOVA test. The statistical significance was set at 0.05. Results: The NCF of WOG and EOF were significantly lower at body temperature as compared to room temperature (p ≤ 0.05), whereas no difference was observed in NCF of HEDM at body and room temperatures (p>0.05). At 20±1°C, the results showed a non-significant difference between NCF of WOG and EOF (p>0.05), while the NCF of HEDM was significantly lower than the other groups (p ≤ 0.05). At 37±1°C, the results showed a non-significant difference in NCF among the tested endodontic files (p ≤ 0.05). There is non-significant difference in FL of each group at (20±1°C) and (37±1°C) (p>0.05). No statistical difference in FL among the tested files at room and body temperatures (p>0.05). Conclusion: The temperature has a significant effect on cyclic fatigue resistance of EOF and WOG, whereas no effect was observed on cyclic fatigue resistance of HEDM. WOG and EOF had a comparable NCF, while HEDM had a lower NCF than other groups at room temperature. At body temperature, all tested files have a comparable NCF. These results were attributed to the type of the alloy and heat treated that was used to manufacture these endodontic files. The cyclic fatigue test should be done at body temperature (AU)

Objetivo : Investigar o efeito das temperaturas ambiente e corpórea na resistência a fadiga cíclica em três instrumentos endodônticos rotatório de níquel-titânio: Hyflex EDM (HEDM)(coltene/Whaledent, Switzerland), WaveOne Gold (WOG) Dentsply Maillefer, Switzer), e EdgeOne Fire (EOF) (EdgeEndo, Albuquerque, New Mexico, USA) em canais com dupla curvatura. Material e Métodos : Neste estudo foram utilizadas sessenta limas endodônticas rotatórias. Esses grupos foram divididos em três grupos (n=20). Grupo A: HEDM (tamanho 25, conicidade 0.08), grupo B: WOG (tamanho 25, conicidade 0.07), e grupo C: EOF (tamanho 25, conicidade 0.07). Cada grupo foi subdivididos em dois subgrupos (n=10). Um dos subgrupos foi submetido ao teste de fadiga cíclica em temperatura ambiente (20±1°C), enquanto o outro subgrupo foi submetido a ao teste de fadiga cíclica em temperatura corpórea (37±1°C). Essas limas foram testadas em um canal artificial feito sob medida com duas curvaturas (curva coronal: curvatura de 60º e com 5 mm de raio; curva apical: curvatura de 70º com 2mm de raio); Todos os instrumentos foram rotacionados de acordo com a instrução do fabricante até que a fratura ocorresse utilizando um motor endodôntico elétrico (Wave One, Dentsply Maillefer, Ballaigues, Switzerland). O número de ciclos até a fratura (NCF) e a comprimento do fragmento fraturado (FL) foram registrados para cada lima endodôntica. Os dados foram coletados e analisados pelo teste shopiro-wilk e ANOVA two-way. A significância estatística foi 0.05. Resultados: O NCF do WOG e do WOF foi significantemente menor na temperatura corpórea em comparação à temperatura ambiente (p ≤ 0.05), enquanto não foi observada diferença entre NCF em HEDM em temperatura corpórea e temperatura ambiente (p>0.05). Em 20±1°C, os resultados mostraram diferença não significativa entre o NFC com WOG e EOF (p>0.05), enquanto o NCF com HEDM foi significante menor que os demais grupos (p ≤ 0.05). A 37±1°C, os resultados mostraram diferença não significativa em NCF entre as limas endodônticas testadas (p ≤ 0.05). Há diferença não significativa no FL de cada grupo (20±1°C) e (37±1°C) (p>0.05). Não houve diferença estatisticamente diferente no FL entre as limas testadas nas temperaturas ambiente e corporal (p>0,05). Conclusão: A temperatura tem efeito significativo na resistência a fadiga cíclica do EOF e WOG, enquanto não foi observado nenhum efeito na resistência a fadiga cíclica do HEDM. WOG e EOF tiveram um NCF comparável, enquanto HEDM teve um NCF menor do que os outros grupos em temperatura ambiente. À temperatura corporal, todas as limas testas apresentam semelhante NCF. Esses resultados foram atribuídos ao tipo de liga e ao tratamento térmico que foi utilizado na fabricação. O teste de fadiga cíclica deve ser feito à temperatura corporal (AU)

INTRODUCCIÓN: La enfermedad por el coronavirus 2019 (COVID-19) causada por el coronavirus 2 del Síndrome respiratorio agudo grave ó SARS-CoV-2 fue inicialmente reportada en Wuhan, China en diciembre de 2019(1) WHO. El 30 de enero de 2020 la OMS determinó que la COVID-19 representaba una emergencia de salud pública de importancia internacional y posteriormente el 11 de marzo del 2020 fue declarada como pandemia. Con el objetivo de contener, suprimir o mitigar esta pandemia, los países han aplicado diversas medidas de salud pública, algunas más restrictivas que otras. Mediante Decreto Supremo No 008-2020-SA, se declara la emergencia sanitaria a nivel nacional por el plazo de noventa (90) días calendario y se dictaron medidas para la prevención y control para evitar la propagación del COVID-19, la misma fue prorrogado por los Decretos Supremos No 020-2020-SA, No 027-2020-SA, No 031-2020-SA, No 009-2021-SA y N° 025-2021-SA, con la finalidad de mitigar la transmisión del virus y proteger la salud de los trabajadores y del público en general (2). El presente documento está destinado a sistematizar la evidencia existente, respecto a la efectividad de las intervenciones no farmacológicas para la prevención y control de COVID-19. OBJETIVO; Sintetizar y presentar disposiciones sobre las recomendaciones actualizadas para el cuidado y disminución del riesgo de contagio por SARS-CoV-2, a partir de revisiones sistemáticas sobre la efectividad de las intervenciones no farmacológicas para la prevención y control de COVID-19. Se efectuó una búsqueda avanzada en la Plataforma Living Overview of the Evidence (L·OVE) de la Fundación Epistemonikos (3) con fecha 21 de octubre del 2021, a fin de identificar revisiones sistemáticas incluyendo revisiones rápidas para la pregunta PICO. Se eligió la plataforma L·OVE ya que ésta actualiza búsquedas de estudios en COVID-19 en alrededor de 39 bases de datos, incluyendo MEDLINE, EMBASE, Biblioteca Cochrane, servidores de distribución de manuscritos aún no publicados y registros de ensayos clínicos entre otras. Adicionalmente, se consultó la página web de la Organización Mundial de Salud (OMS) y de algunas páginas oficiales de las principales agencias gubernamentales de la región, sobre a la efectividad de las intervenciones no farmacológicas (uso de pediluvio, toma de temperatura y distanciamiento físico) para la prevención y control de COVID-19. RESULTADOS: Las intervenciones no farmacológicas comprenden medidas de protección personal, medidas medioambientales, medidas de distanciamiento físico y medidas relacionadas con el tránsito, la adopción de esas medidas se está aplicando como respuesta a la propagación de la COVID-19. Las consideraciones presentadas en esta nota técnica se refieren a las medidas como el distanciamiento social, toma de temperatura y el uso de pediluvios. CONCLUSIONES: El objetivo del informe fue sintetizar y presentar disposiciones sobre las recomendaciones actualizadas para el cuidado y disminución del riesgo de contagio por SARS-CoV-2, a partir de revisiones sobre la efectividad de las intervenciones no farmacológicas para la prevención y control de COVID-19, estas intervenciones son el distanciamiento físico, toma de temperatura y el uso de pediluvios. Al inicio de la pandemia del COVID-19, se recomendaron diversas medidas preventivas por el principio de precaución, con evidencia científica limitada acerca de la seguridad y en relación a los riesgos y la factibilidad asociados a su implementación. Una de las intervenciones es el distanciamiento físico, la reducción de la transmisión de SARS-CoV-2 se ha podido comprobar mediante simuladores sin mascarilla, con una reducción del 60% a 50 cm y del 70% a 1 metro, por lo que la exposición a aerosoles infectivos en espacios mal ventilados o mayor número de personas en aforos reducidos, aumenta la posibilidad de contagio. Es necesario implementar medidas para mantener un distanciamiento físico seguro entre las personas. En cuanto a la toma de temperatura, según un estudio analizado, tiene una sensibilidad muy baja, a pesar de que podría presentar una mejor especificidad, (es decir, es más probable que una temperatura alta refleje una infección que requeriría pruebas confirmatorias que un falso positivo), la utilidad del cribado con medición directa de temperatura puede ser limitada dada a la escasa sensibilidad (es decir, una temperatura normal no identifica muchas infecciones verdaderas) porque la historia natural de esta infección incluye una duración presintomática y muchas veces el curso es asintomático de la enfermedad. Cabe mencionar que este estudio fue al principio de la pandemia, actualmente la toma de temperatura como recomendaciones para el ingreso a iglesias, centros comerciales, colegios o lugares públicos no está dentro de las recomendaciones de la OMS. En cuanto al uso de pediluvios, no se encontró evidencia científica que ayude a la reducción de la posible diseminación del virus COVID-19, además no figura dentro de las recomendaciones de la OMS. La utilidad limitada de los enfoques actuales, es decir la poca o nula evidencia científica que sustente la toma de temperatura para el ingreso en colegios, instituciones públicas, restaurantes, centros comerciales, etc, y el uso de pediluvios para evitar la propagación del virus, nos lleva a la necesidad en un mayor énfasis de priorizar otras intervenciones como el uso de la mascarilla, mantener el distanciamiento físico y social, lavado de manos y utilizar equipos de protección personal.

O objetivo do presente estudo foi avaliar os efeitos do exercício prévio específico sobre o desempenho em teste intermitente de alta intensidade em jogadoras de futsal e variáveis associadas. Para isso 13 jogadoras amadoras de futsal (24,1 anos; 63,6 kg; 1,61 m; IMC = 24,3 kg/m2 ; % de gordura = 27,9), de maneira cruzada, passaram por duas sessões experimentais separadas por sete dias. Em uma das sessões era realizado um exercício prévio (EP): três primeiros níveis do Yo Yo intermittent recovery test level 1 (YYIR1) repetidos por três vezes. Na sessão controle (CON), as jogadoras permaneciam em repouso (5 min) e após, em ambas as sessões, era realizado o YYIR1 até a exaustão. Antes do início da sessão eram reportadas escalas de recuperação e dor muscular de início tardio, a frequência cardíaca (FC) foi monitorada por toda sessão e, ao término, a percepção de esforço (PSE) era registrada. As percepções de recuperação (p = 0,23) e de dor (p = 0,36) não diferiram entre as sessões EP vs. CON. A FC média durante o exercício prévio foi de 111,3 ± 7,7 bpm. A distância percorrida no YYIR1 não diferiu (p = 0,25) também entre EP (372,3 ± 103,8 m) vs. CON (341,5 ± 84,2 m), bem como a monitoração da FC (mínima, média e máxima). Entretanto, a PSE foi menor (p = 0,0008) na sessão EP (8,5 ± 0,7 UA) do que em CON (9,3 ± 0,6 UA). Assim, concluímos que o exercício prévio não influencia o desempenho intermitente de alta intensidade (YYIR1), nem as variáveis de FC. Porém, o exercício prévio gera menores níveis de percepção de esforço (intensidade interna) em comparação ao repouso antes do YYIR1. (AU)

The aim of the present study was to evaluate the effects of specific prior exercise on performance in intermittent high intensity testing in futsal players and associated variables. For this, 13 amateur futsal players (24.1 years old; 63.6 kg; 1.61 m; BMI = 24.3 kg / m2; fat% = 27.9), in a crossed way, went through two experimental sessions separated by seven days. In one of the sessions, a previous exercise (PE) was performed: the first three levels of the Yo Yo intermittent recovery test level 1 (YYIR1) repeated three times. In the control session (CON), the players remained at rest (5 min) and afterwards, in both sessions, YYIR1 was performed until exhaustion. Before the start of the session, recovery scales and late-onset muscle pain were reported, the heart rate (HR) was monitored throughout the session and, at the end, the perceived exertion (RPE) was recorded. The perceptions of recovery (p = 0.23) and pain (p = 0.36) did not differ between the PE vs CON. The average HR during the previous exercise was 111.3 ± 7.7 bpm. The distance covered in YYIR1 did not differ (p = 0.25) also between PE (372.3 ± 103.8 m) vs. CON (341.5 ± 84.2 m), as well as HR monitoring (minimum, average and maximum). However, the RPE was lower (p = 0.0008) in the PE session (8.5 ± 0.7 AU) than in CON (9.3 ± 0.6 AU). Thus, we conclude that the previous exercise does not influence the intermittent high intensity performance (YYIR1), nor the HR variables. However, previous exercise generates lower levels of perceived exertion (internal intensity) compared to resting before YYIR1. (AU)

This study aimed to determine the physiological and hematological parameters of sheep in Brazil. Therefore, 5,081 observations were used from previous experiments with animals from different Brazilian regions with the time of day, gender, breed, age, physiological characteristics, hematological and climatic variables. The animals were classified according to their stress level, and only data of non-stressed animals were used to calculate the reference values. Respiratory rate was the parameter that most differed from the normal range, with values ​​above the limits usually reported for the species, being higher in commercial wool sheep. For hematological variables, differences were observed between the present results and the previously reported values in the literature. A higher number of red blood cells (RBC), lower hemoglobin and mean corpuscular hemoglobin concentration (MCHC) were observed in young animals. A higher number of RBC and MCHC were noted in sheep crossed with local breeds. Considering that physiological and hematological parameters are indicators of the animal's pathological or physiological state, for a correct interpretation of the results, the use of reference values based on animals with similar racial characteristics and subjected to similar environmental conditions is recommended.(AU)

O objetivo deste estudo foi determinar parâmetros fisiológicos e hematológicos de ovinos no Brasil. Portanto, foram utilizadas 5.081 observações de experimentos anteriores com animais de diversas regiões do Brasil, com diferentes horário, sexo, raça, idade, características fisiológicas, variáveis ​​hematológicas e climáticas. Os animais foram classificados de acordo com o nível de estresse, e apenas os dados dos animais não estressados ​​foram utilizados para o cálculo dos valores de referência. A frequência respiratória foi o parâmetro que mais diferiu em relação à normalidade, com valores acima dos limites usualmente relatados para a espécie, sendo maior em ovinos de lã comercial. Para as variáveis ​​hematológicas, também foram verificadas diferenças entre os resultados observados e os valores previamente relatados na literatura. Maior número de hemácias, menor hemoglobina e concentração de hemoglobina corpuscular média (CHbCM) foram observados em animais jovens e maior número de hemácias e CHbCM em ovinos cruzados com raças locais. Considerando que os parâmetros fisiológicos e hematológicos são indicadores do estado patológico ou fisiológico do animal, para uma correta interpretação dos resultados recomenda-se a utilização de valores de referência baseados em animais com características raciais semelhantes e submetidos a condições ambientais também semelhantes.(AU)

This study aims to determine the relationship between indicators of the motor activity, pH factor, rumen and rectal temperature within 10 days after calving and to analyze the possibility of using the studied parameters as prognostic signs for diagnosing sub-acute rumen acidosis (SARA). The measurements were taken using bolus with sensors designed to monitor cow health. The motor activity, pH factor and ruminal temperature of 10 cows were measured during 10 days at a measurement interval of every 60 seconds. Next, the researchers calculated the average values of the obtained readings, which were divided into 2 groups according to a measurement interval of every 12 hours. Rectal temperature was measured using a veterinary thermometer every 12 hours (at 8 a.m. and at 8 p.m.). As a result, 200 measurements were obtained. Descriptive sampling statistics were calculated using the SPSS Statistics program. An increase in motor activity reduces the pH level of the rumen environment. Lowering the pH factor of the rumen environment leads to an increase in ruminal temperature. There is a positive statistically significant correlation between ruminal and rectal temperature. The nosology of SARA can be predicted by measuring the motor activity and rectal temperature of dairy cows.(AU)

Este estudo visa determinar a relação entre indicadores de atividade motora, fator de pH, temperatura ruminal e retal em até 10 dias após o parto e analisar a possibilidade de utilizar os parâmetros estudados como sinais prognósticos para o diagnóstico de acidose ruminal subaguda (SARA). As medições foram feitas usando bolus com sensores projetados para monitorar a saúde das vacas. A atividade motora, o fator de pH e a temperatura ruminal de 10 vacas foram medidos durante 10 dias em intervalos de medição de 60 segundos. A seguir, os pesquisadores calcularam os valores médios das leituras obtidas, que foram divididos em 2 grupos de acordo com um intervalo de medição a cada 12 horas. A temperatura retal foi medida com um termômetro veterinário a cada 12 horas (às 8h e às 20h). Como resultado, foram obtidas 200 medições. As estatísticas de amostragem descritiva foram calculadas usando o programa SPSS Statistics. Um aumento na atividade motora reduz o nível de pH do ambiente ruminal. A redução do fator de pH do ambiente ruminal leva a um aumento da temperatura ruminal. Existe uma correlação positiva estatisticamente significativa entre a temperatura ruminal e retal. A nosologia com SARA pode ser prevista medindo a atividade motora e a temperatura retal de vacas leiteiras.(AU)

Ten free-living adult coatis (two males and eight females) were chemically restrained with "ZAD-50", a concentrated formulation prepared with the dehydrated content of a Zoletil/50® vial diluted with 0.25mL of 1% atropine, 0.265mL of Dormiun-V®, and 2.2mL of distilled water, being exactly 3.0mL. The formula was administered to each animal previously captured and physically contained with a net. The loss of righting reflex (RR) occurred at 2.3±0.8 minutes post-injection (MPI), with anesthesia beginning at 4.4±2.7 MPI. Myorelaxant and analgesia were considered excellent at all moments of the evaluation. Conscious reactions were observed at 78.7±22.2 MPI, the return of the RR occurred at 101 ± 18 MPI, and normal ambulation was acquired at 137.0±31.0 MPI. The mean values ​​of physiological parameters measured every 10 minutes between 10 and 50 MPI were 152.2 heartbeats per minute for heart rate, 66.4 respiratory movements per minute for respiratory rate, 39.2oC for rectal temperature, 86.2% for SpO2 and 14.6 mmHg for systolic blood pressure. In the same times, the EEG registered sinus rhythm. No adverse reactions were observed, and the assessed vital parameters remained compatible with the state of chemical restraint.(AU)

ABSTRACT Introduction Infrared thermography has been used in several areas, mainly in sports training, and specifically in soccer. Objectives The objectives of the study were to verify the acute effect of a displacement speed test on the skin temperature of elite female soccer players, to observe pre- and post-test thermal asymmetries, and to compare responses in the anterior and posterior regions of lower limbs. Methods Cross-sectional study that evaluated 17 soccer players of the 2018 Brazilian Championship. They were submitted to thermography before and 10 minutes after performing the displacement speed test. Thermographic images were collected using a FLIR® model 8 thermal imager and changes in skin temperature in the anterior and posterior regions of the lower limbs were analyzed, according to the areas of interest. Descriptive statistics were performed and mean and standard deviation of the temperatures of the areas of interest were analyzed. The normality of the data was verified, and then the Student's t test for normal paired and independent samples and the Mann-Whitney test for non-normal samples were conducted, with p <0.05 being adopted for significance level. Results It was possible to observe that after the test there was an increase in skin temperature in all the regions analyzed, both on the dominant and non-dominant sides (p <0.05). Regarding the analysis of the anterior region, it was possible to observe a higher temperature (p <0.05) in the region of the tibial muscles than in the region of the quadriceps muscles. Conclusion It is concluded that thermography helps to understand the thermal responses of lower limbs after applying the displacement speed test. The study shows that thermographic evaluation can guide the organization of the training session when motor tests have previously been applied, and in the detection of abnormal overloads, helping to prevent injuries.

According to different publications, the neurological level most frequently involved in traumatic spinal cord injury is cervical (16%-75%), followed by thoracic (16%-36%) and lumbar (9%-17%). The abrupt interruption of nerve conduction at the spinal level causes spinal shock, characterized by an acute neurological, hemodynamic, respiratory and urinary compromise, which associates with thermoregulation problems. Neurological repercussions are characterized by a motor compromise, evidenced as flaccid paralysis with areflexia, sensory damage, abolition of sympathetic activity and loss of adaptive reflexes in the territory located below the lesion. The management of traumatic spinal cord, both, isolated or associated with multiple trauma, must begin at the scene of the accident. The current trend is towards a selective immobilization identifiying the group of patients in whom it will have a real benefit. Clinical features of spinal shock and other clinical aspects of the spinal cord injury are described in detail. Diagnosis should include a complete neurological examination including imaging studies. The type of image of choice is computerized axial tomography (CT). Different treatment alternatives are analyzed, including early or delayed descompressive surgery, methylprednisolone, neuroprotection and neuroregeneration. Finally, anesthetic management is described, the objective of which should be to reduce the movement of the lesion area (especially during positioning and the laryngoscopy and intubation maneuver) and to maintain the medullary perfusion pressure within normal limits. Postoperative care should focus on pain management, prevention of thromboembolic events and weaning from mechanical ventilation.

El nivel neurológico más frecuentemente comprometido en las lesiones raquimedulares por trauma es el cervical (16%-75%), seguido del torácico (16%-36%) y lumbar (9%-17%) según diferentes publicaciones. La brusca interrupción de la conducción nerviosa a nivel medular origina el cuadro de medular, caracterizado por un agudo compromiso neurológico, hemodinámico, respiratorio y urinario, asociado a problemas de termorregulación, con repercusiones neurológicas caracterizadas por un compromiso motor que se manifiesta como una parálisis fláccida con arreflexia, daño sensitivo, desaparición de la actividad simpática y pérdida de reflejos de adaptación en el territorio ubicado por debajo de la lesión. El manejo del trauna raquimedular asociado o no a politraumatismo debe inicirse en la escena del accidente; la tendencia actual es hacia una inmovilización selectiva, haciendo una identificación del grupo de pacientes en los que tendrá un real beneficio. Se describe detalladamente el cuadro de medular o espinal y otros aspectos clínicos de la sección medular. El diagnóstico debe incluir un examen neurológico completo y estudios de imagenología; el tipo de imagen de elección es la tomografía axial computarizada (TAC). Se analizan las diferentes alternativas de tratamiento: cirugía descompresiva precoz o diferida, metilprednisolona, neuroprotección y neurorregeneración. Finalmente se detalla el manejo anestésico, cuyo objetivo debe perseguir el menor movimiento de la zona de la lesión (especialmente durante el posicionamiento y la maniobra de laringoscopía e intubación) y el mantenimiento de la presión de perfusión medular dentro de los límites más estables posilbes. Los cuidados posoperatorios deben estar dirigidos especialmente al manejo de la analgesia, la prevención de la enfermedad tromboembólica y la desconexión de la ventilación mecánica.

Traumatic brain injury (TBI) is the leading cause of death and disability for children and young adults. The Glasgow Coma Scale allows to classify TBI as mild, moderate and severe. Imaging studies show the heterogeneity of the diagnosis. Primary injury is caused by mechanical impact. Secondary injury contributes significantly to prognosis by exacerbating hypoperfusion and intracranial hypertension. Even in the absence of extracranial lesions, many patients with severe TBI present significant organ dysfunction, which transforms TBI into a multisystemic pathology. Most relevant systems compromised include cardiovascular, autonomic, respiratory and coagulation. The main aims of anesthetic management are: early decompression together with prevention, early detection, and management of determinants of secondary injury. To date, there are no techniques or drugs showing a significant impact on the outcome of TBI patients. On the other hand, maintaining good hemodynamic stability, adequate oxygenation and normocarbia all contribute to a better outcome.

El trauma encéfalocraneano (TEC) es la causa más importante de muerte y discapacidad de niños y adultos jóvenes. La escala de Glasgow permite clasificarlo en leve, moderado y severo. La imagenología da cuenta de la heterogeneidad del diagnóstico. La injuria primaria es la causada por el impacto mecánico. La injuria secundaria contribuye significativamente al pronóstico al exacerbar la hipoperfusión y la hipertensión endocraneana. Aun en ausencia de lesiones extracraneales, gran parte de los pacientes con TEC severo presenta disfunción orgánica significativa, lo que lo transforma en una patología multisistémica. Destacan el compromiso cardiovascular, autonómico, respiratorio y trastornos de la coagulación, entre otros. Los objetivos del manejo anestésico son: la descompresión precoz junto con la prevención, detección temprana y manejo de factores determinantes de injuria secundaria. No existe evidencia respecto de técnicas ni fármacos que hayan demostrado un impacto significativo en el manejo del TEC, más bien, impacta positivamente el mantener la estabilidad hemodinámica, una adecuada oxigenación y normocarbia.

Perioperative hypothermia is a common complication of general anesthesia, but it can also occur in patients undergoing regional anesthesia. It signifiicantly increases perioperative morbidity and mortality. Complications such as increased incidence of surgical site infection, delayed healing, coagulation abnormalities, increased surgical bleeding, perioperative cardiac events, decreased metabolism of drugs involved in anesthesia and a great discomfort in the immediate postoperative period (due to shivering), have been identified. The decrease in the patient's core temperature is due to a combination of physiological events related to the surgical anesthetic act. These include deterioration of the effector responses of the hypothalamus (tending to conserve heat), heat distribution between the central compartment and the periphery, and net heat loss to a generally colder environment, such as the surgical ward. Hypothermia is often an undetected complication of the anesthetic act due to the lack of regular temperature monitoring. It is not considered a basic standard of care, despite the fact that in recent years new guidelines and recommendations have emerged, which suggest its implementation in all patients in whom the duration of their surgery is expected to last longer than 1 hour. The measures aimed at keeping the patient normothermic can be classified as passive, within which the simplest is to cover the patient for as long as possible during their presence in the ward, and active, which are those that transfer heat to the body, within the which the most effective is the use of convective heat blankets. It has recently been suggested that prewarming the patient before inducing anesthesia is an efficient strategy to avoid hypothermia, decreasing temperature differences between core and peripheral tissues. However, the effectiveness of this measure remain to be evaluated with prospective, randomized trials. In the context of the emergency patient, although hypothermia shows the same characteristics as in the elective patient, it becomes more relevant in three clinical settings: patient with major burns, patient in hemorrhagic shock and the polytraumatized patient. In these scenarios, keeping the patient normothermic will prevent a series of serious complications, which can strongly affect mortality.

La hipotermia perioperatoria es una complicación frecuente de la anestesia general, pero que también se puede presentar en pacientes sometidos a anestesia regional. Se relaciona con un aumento significativo de la morbilidad y mortalidad perioperatorias, donde se han identificado complicaciones como aumento de la incidencia de infección del sitio quirúrgico, retardo de la cicatrización, alteraciones de la coagulación, aumento del sangrado quirúrgico, de los eventos cardiacos perioperatorios, disminución del metabolismo de drogas implicadas en la anestesia y sensación de gran incomodidad del paciente en el posoperatorio inmediato, por la presencia de calosfríos. La disminución de la temperatura central del paciente se debe a un combinación de eventos fisiológicos relacionados con el acto anestésico quirúrgico, con deterioro de las respuestas efectoras del hipotálamo tendientes a conservar calor, fenómenos distributivos de calor entre el compartimiento central y la periferia del propio paciente y pérdida de calor neta hacia un medio ambiente en general más frío, como lo es el pabellón quirúrgico. El hecho de que la hipotermia sea muchas veces considerada una complicación no detectada del acto anestésico, se debe a que aún la monitorización regular de la temperatura no se considera un estándar básico de cuidado, pese a que en los últimos años han surgido nuevas guías y recomendaciones, que sugieren que ésta sea implementada en todo paciente en que se proyecte una duración de la cirugía mayor a 1 hora. Las medidas tendientes a mantener al paciente normotérmico, pueden ser clasificadas en pasivas, dentro de las cuales la más simple es cubrir al paciente el mayor tiempo posible durante su presencia en pabellón y activas, que son aquellas que transfieren calor al cuerpo, dentro de las cuales la más efectiva es el uso de mantas de calor convectivo. Recientemente, se ha sugerido que una de las estrategias eficientes para evitar la HPO es el precalentamiento del paciente, que permite que sus tejidos periféricos estén a mayor temperatura al momento de inducir la anestesia, sin embargo, la efectividad de esta medida debe ser evaluada con estudios prospectivos y aleatorizados más concluyentes. La hipotermia en el contexto del paciente de urgencia, si bien presenta las mismas características que en el paciente electivo, cobra mayor relevancia en tres escenarios clínicos: el gran quemado, el paciente en hemorrágico y el paciente politraumatizado, escenarios en que mantener al paciente normotérmico, implicará evitar una serie de complicaciones graves, que pueden incidir fuertemente en la mortalidad.

Abstract Objective: To evaluate the reliability of infrared (IR) thermal camera connected to smartphones, already used in medicine for diagnostic purposes, as an easy tool for access screening to pediatric dentistry services. Material and Methods: After the preventive telephone triage, thirty orthodontic patients (7-13 years) underwent temperature measurement in the office with two no-contact IR devices: forehead digital thermometer and thermal-camera connected to a smartphone (reference areas: forehead, inner canthi, ears). Measurements were compared and differences were statistically investigated with T student's test (p<0.01). Results: Forehead digital thermometer temperatures were superimposable to those recorded in ear areas and inner canthi with the thermal camera connected to a smartphone. Differences were not statistically significant even in comparison between the sexes. Forehead temperature values detected with a thermal camera are lower than those detected with a digital forehead thermometer. Conclusion: Thermal camera on a smartphone could be reliable in measuring body temperature. Mobile thermographic values of ears and inner canthi areas can be used as an alternative to forehead digital thermometer measurements. Further applications in pediatric dentistry of thermography on smartphones should be examined.
