ABSTRACT BACKGROUND: High-resolution manometry (HRM) represents a potential tool for measuring pharyngoesophageal phonation pressures. OBJECTIVE: This study aims to evaluate pharyngeal, esophageal upper sphincteric and esophageal pressures during different phonation tasks. METHODS: 12 (six males, mean age 27 years) professional singers underwent HRM and produced four different vocal tasks at low, medium and high vocal loudness: vowel /ae/, ascending five note scale, word /hey/ and word /go/. Pressures were measured at pharynx, upper esophageal sphincter (UES) and esophagus. Visual analysis of the HRM topographic plots were performed. RESULTS: Esophageal pressures are higher during vocalization than at rest. Pharyngeal and UES phonation pressures does not differ significantly from rest pressures. Visual analysis of the topographic plots showed an important UES pressure increasement during phonation. CONCLUSION: HRM is a valuable tool for measuring pharyngoesophageal pressures during phonation. Esophageal pressures are higher during phonation than at rest and tend to increase with vocal loudness increment. The topographic plot provides additional data about phonatory mechanism physiology, especially at the UES region.

RESUMO CONTEXTO: A manometria de alta resolução (MAR) é uma ferramenta de grande potencial para mensuração das pressões faringoesofágicas durante a fonação. OBJETIVO: O estudo visa avaliar pressões faringianas, do esfíncter esofagiano superior e do esôfago durante manobras fonatórias. MÉTODOS: Doze (seis homens, idade média 27 anos) cantores profissionais foram submetidos à MAR e produziram quatro tarefas vocais em intensidade baixa, média e alta: vogal / ae /, escala ascendente de cinco notas, palavras /hey/ e /go/. Pressões aos níveis da faringe, esfíncter esofagiano superior e esôfago foram aferidas além de análise visual dos traçados. RESULTADOS: Pressões esofágicas foram maiores na vocalização que no repouso. Pressões da faringe e esfíncter esofagiano superior durante a fonação não foram diferentes que no repouso. Análise visual dos traçados mostrou importante incremento da pressão do esfíncter durante a fonação. CONCLUSÃO: MAR é uma ferramenta valiosa para mensurar as pressões faringoesofágicas durante a fonação. Pressões esofágicas são maiores durante a fonação que no repouso e tendem a aumentar com maior intensidade sonora. Análise visual dos traçados mostram dados adicionais sobre a fisiologia do mecanismo da fonação, especialmente na região do esfíncter esofagiano superior.

OBJETIVO:Comparar el promedio de curva de presión de contacto y el porcentaje de presión de contacto residual final en la interfase tendón-huella de una reparación transósea (TO) realizada con nudos cruzados y una configuración Mason-Allen modificada (MAM). MÉTODOS: Se utilizaron ocho hombros de cordero para simular una rotura de manguito rotador. Se midió la presión con un sensor digital. Se registró la presión basal durante la aplicación de carga cíclica y al final de la intervención. Se compararon dos reparaciones: dos túneles TOs con nudos cruzados (TOCs) (n » 4) y dos puntos MAMs (n » 4) utilizando suturas MaxBraid #2 (Zimmer Biomet, Warsaw, IN, EEUU). Se realizaron 1.000 ciclos, con una frecuencia de 2 Hz y una carga de 30 N. Se utilizó el test de t de Student, y se consideraron significativos valores de p < 0,05. RESULTADOS: El promedio de curva de presión de contacto en las piezas que fueron reparadas con suturas TOCs fue de 86,01 8,43%, mientras que con MAM fue de 73,28 12,01% (p < 0,0004). El promedio del porcentaje residual al final del ciclado fue de 71,57% para suturas TOCs y de 51,19% para MAM (p < 0,05). CONCLUSION: La reparación TOC presenta mayor promedio de curva de presión de contacto y mayor porcentaje de presión de contacto residual final en la interfase tendón-huella que la reparación con sutura MAM luego de carga cíclica estandarizada, lo que podría traducirse en una mejor cicatrización del tendón. NIVEL DE EVIDENCIA: Estudio de ciencia básica.

OBJECTIVE: To compare the average contact pressure curve and the percentage of final residual contact pressure at the tendon-footprint interphase of a transosseous (TO) repair performed with crossover sutures or a modified Mason-Allen (MMA) configuration. METHODS: Eight lamb shoulders were used to simulate a rotator cuff tear. The pressure was measured with a digital sensor. The baseline pressure was recorded during the application of the cyclic load and at the end of the intervention. Two repairs were compared: 2 crossover TO (CTO) sutures (n » 4) and 2 MMA sutures MMA (n » 4), using MaxBraid #2 (Zimmer Biomet, Warsaw, IN, US) sutures. A thousand cycles were performed, with a frequency of 2 Hz and a 30-N load. The Student t-test was used, and significance was set at p < 0.05. RESULTS: The average contact pressure curve was of 86.01 8.43% for parts repaired with CTO sutures, and of 73.28 12.01% for those repaired with MMA sutures (p < 0.0004). The mean residual percentage at the end of cycling was of 71.57% for CTO sutures, and of 51.19% for MMA sutures (p < 0.05). CONCLUSION: The CTO repair shows a higher average contact pressure curve and a higher percentage of final residual contact pressure at the tendon-footprint interphase than the MMA suture repair after standardized cyclic loading, potentially resulting in improved tendon healing. LEVEL OF EVIDENCE: Basic Science Study.

ABSTRACT Purpose: High intra-renal pressures during flexible ureteroscopy have been associated with adverse renal tissue changes as well as pyelovenous backflow. Our objective was to investigate the effect of various intra-renal pressures on histologic changes and fluid extravasation during simulated ureteroscopy. Materials and Methods: Twenty-four juvenile pig kidneys with intact ureters were cannulated with an Olympus flexible ureteroscope with and without a ureteral access sheath and subjected to India ink-infused saline irrigation for 30 minutes at constant pressures ranging from sphygmomanometer settings of 50mm, 100mm and 200mmHg. Renal tissue samples were collected, processed and stained, and were evaluated by a blinded pathologist for depth of ink penetration into renal parenchyma as a percentage of total parenchymal thickness from urothelium to renal capsule. Results: The mean percentage of tissue penetration for kidneys with ink present in the cortical tubules at sphygmomanometer pressure settings of 50, 100, and 200mm Hg without a ureteral access sheath was 33.1, 31.0 and 99.3%, respectively and with ureteral access sheath was 0, 0 and 18.8%, respectively. Overall, kidneys with an access sheath demonstrated a smaller mean tissue penetration among all pressure compared to kidneys without a sheath (6.3% vs. 54.5%, p=0.0354). Of kidneys with sheath placement, 11% demonstrated any ink compared to 56% of kidneys without sheath placement. Conclusions: Pressurized endoscopic irrigation leads to significant extravasation of fluid into the renal parenchyma. Higher intra-renal pressures were associated with increased penetration of irrigant during ureteroscopy in an ex-vivo porcine model.

RESUMO Objetivo Sintetizar o estado do conhecimento científico sobre biomecânica da língua durante a deglutição após laringectomia total. Estratégia de pesquisa Formulou-se a questão PICO e combinações de descritores e termos livres para busca nas bases de dados PubMed/Medline, EMBASE, LILACS e SciELO. Critérios de seleção incluíram-se artigos nos idiomas português, inglês ou espanhol; sem limite de tempo; com resultados sobre a biomecânica da língua durante a deglutição em laringectomizados totais; e estudos do tipo ensaio clínico randomizado ou não randomizado, coorte, caso controle, transversal, série de casos e estudos de caso. Análise dos dados analisou-se ano, país, população, objetivo, delineamento do estudo, instrumentos de avaliação, principais desfechos e qualidade metodológica. Resultados Foram incluídos quatro estudos realizados nos Estados Unidos, um na Austrália e um no Brasil, publicados entre 1986 e 2014. Em todos os estudos incluídos a biomecânica da língua foi um desfecho secundário. A maioria dos artigos teve baixa qualidade metodológica, com amostras pequenas, predomínio do sexo masculino e desenho transversal prevalente. Os instrumentos de avaliação foram videofluoroscopia, manometria, acelerômetro ou dispositivo para captar pressão de língua. Resultados principais indicaram mais força de propulsão da base de língua para superar a alta resistência da neofaringe ao fluxo do bolo alimentar; redução do contato e pressão entre base de língua e parede posterior da faringe; resíduo em base de língua após deglutição; pressão aumentada e resistência reduzida da língua oral. Conclusão Existem indícios de movimentos compensatórios de língua durante a deglutição após laringectomia total, porém, as evidências científicas são insuficientes.

ABSTRACT Purpose To synthesize the state of scientific knowledge about biomechanics of the tongue during swallowing after total laryngectomy. Research strategy The PICO question and combinations of descriptors and single terms were formulated in the PubMed/Medline, EMBASE, LILACS, and SciELO databases. Selection criteria Articles in Portuguese, English, or Spanish were included, without time limit, with results on the biomechanics of the tongue during swallowing and total laryngectomy, and studies on randomized or non-randomized clinical trials, cohort, case control, cross-sectional, case series, and case studies. Data analysis year, country, population, objective, study design, assessment methods, main outcomes, and methodological quality were analyzed. Results There were four studies in the United States, one in Australia, and one in Brazil, all published between 1986 and 2014. In all studies, the biomechanics of the tongue was the secondary outcome. Most articles had low methodological quality, small samples, predominance of the male gender, and a prevalent cross-sectional design. The assessment instruments were fluoroscopy, manometry, accelerometer or a device to capture tongue pressure. Main results indicated a higher propulsion force of the tongue base to overcome the high resistance of the neopharynx to the bolus flow, reduced contact and pressure between the base of the tongue and the posterior pharyngeal wall, residues in the tongue base after swallowing, increased pressure, and reduced resistance of the oral tongue. Conclusion There are indications of compensatory tongue movements during swallowing after total laryngectomy; however, the scientific evidence is insufficient.

El trabajo respiratorio se ejerce en una estructura cerrada donde se encuentran los pulmones, estos son sometidos a cambios de presiones determinados por la musculatura pulmonar en las diferentes fases del ciclo respiratorio, lo que generará gradientes y permite la entrada y salida de aire. Se suman a ello el calibre de las vías aéreas, el tipo de flujo, las características de las vías aéreas y del surfactante pulmonar, que determinan un menor o mayor trabajo respiratorio según la condición fisiológica.

The work of breathing is exerted in a closed structure where the lungs are located. These are subjected to pressure changes determined by the pulmonary musculature in the different phases of the respiratory cycle, which will generate gradients and allow the entry and exit of air. In addition to the aforesaid, airway calibre, type of flow, airway characteristics and pulmonary surfactant determine less or more work of breathing depending on the physiological condition.

Abstract Background and objectives Several airway complications can occur during shoulder arthroscopy including airway obstruction, pleural puncture, and subcutaneous emphysema. It was hypothesized that the irrigation fluid used during a shoulder arthroscopic procedure might increase the cuff pressure of the endotracheal tube, which can cause edema and ischemic damage to the endotracheal mucosa. Therefore, this study aimed to evaluate the relationship between irrigation fluid and endotracheal tube cuff pressures. Methods Forty patients aged 20 to 70 years with an American Society of Anesthesiologists (ASA) score I or II, scheduled for elective arthroscopic shoulder surgery under general anesthesia, participated in our study. We recorded endotracheal tube cuff pressures and neck circumferences every hour from the start of the operation. We also recorded the total duration of the anesthesia, operation, and the total volume of fluid used for irrigation. Results A positive correlation was shown between endotracheal tube cuff pressures and the amount of irrigation fluid (r = 0.385, 95% CI 0.084 to 0.62, p = 0.0141). The endotracheal tube cuff pressure significantly increased at 2 and 3 hours after starting the operation (p = 0.0368 and p = 0.0245, respectively). However, neck circumference showed no significant difference. Conclusions Endotracheal tube cuff pressures increased with operation time and with increased volumes of irrigation fluid used in patients who underwent shoulder arthroscopy. We recommend close monitoring of endotracheal tube cuff pressures during shoulder arthroscopy, especially during long operations using a large amount of irrigation fluid, to prevent complications caused by raised cuff pressures.

Resumo Justificativa e objetivos Diversas complicações das vias aéreas podem ocorrer durante a artroscopia do ombro, incluindo obstrução das vias aéreas, punção pleural e enfisema subcutâneo. Levantou‐se a hipótese de que o fluido de irrigação utilizado durante artroscopia do ombro possa aumentar a pressão do balonete do tubo endotraqueal, podendo causar edema e lesão isquêmica na mucosa traqueal. Portanto, este estudo teve como objetivo avaliar a relação entre o fluido de irrigação e a pressão do balonete do tubo endotraqueal. Métodos Participaram do estudo 40 pacientes com idades entre 20 e 70 anos com classificação do estado físico I ou II da American Society of Anesthesiologists (ASA), programados para cirurgia artroscópica do ombro, eletiva e sob anestesia geral. Registramos as pressões do balonete do tubo endotraqueal e as circunferências do pescoço a cada hora, a partir do início da cirurgia. Também registramos a duração anestésica e cirúrgica, assim como o volume total de líquido de irrigação empregado. Resultados Foi encontrada correlação positiva entre a pressão do balonete do tubo endotraqueal e a quantidade de líquido de irrigação (r = 0,385; 95% IC 0,084 a 0,62; p = 0,0141). A pressão do balonete do tubo endotraqueal registrou aumento significante 2 e 3 horas após o início da cirurgia (p = 0,0368 e p = 0,0245, respectivamente). No entanto, a circunferência do pescoço não mostrou diferença significante. Conclusões As pressões do balonete do tubo endotraqueal aumentaram com o tempo de cirurgia e com o aumento do volume de líquido de irrigação utilizado em pacientes submetidos a artroscopia do ombro. Recomendamos a monitorização rigorosa da pressão do balonete do tubo endotraqueal durante artroscopia do ombro, especialmente nos procedimentos longos em que grandes volumes de fluido de irrigação são empregados, para evitar complicações causadas por pressões elevadas do balonete.

Resumen La hipertensión portal se define como la alteración patológica en el gradiente de presión a nivel del sistema portal, es decir, la diferencia entre la presión de la vena porta y la vena cava inferior. El valor normal es entre 1-5 mm Hg y se considera hipertensión cuando es mayor de 10 mm Hg. En este artículo, se describe el caso de una paciente de 5 años con un cuadro de hipertensión portal secundario a várices esofágicas y trombosis de la vena porta, confirmado por endoscopia de vías digestivas alta y angioresonancia magnética. La paciente fue atendida en la Fundación Clínica Infantil Club Noel de la ciudad de Cali, Colombia, entre los meses de diciembre del 2018 y febrero del 2019.

Abstract Portal hypertension is defined as the pathological increase in the portal pressure gradient, which is the difference between the pressure of the portal vein and the inferior vena cava. Normally portal vein pressure ranges between 1-5 mmHg and is considered hypertension when it is higher than 10 mmHg. In this study the case of a 5-year-old patient that suffers from secondary portal hypertension to portal venous thrombosis and esophageal varices is presented. The diagnostic is confirmed by an endoscopy of the upper gastrointestinal tract and by a magnetic angioresonance. The patient was treated at the Fundacion Clinica Infantil Club Noel located in Cali, Colombia, between the months of December 2018 and February 2019.

RESUMEN: Los pulmones son el sitio predominante en la infección por COVID-19. Esta puede conducir al síndrome distrés respiratorio agudo (SDRA). Frente a su sintomatología severa, la ventilación mecánica (VM), y sus valores de mecánica ventilatoria aparecen como una herramienta fundamental. Un complemento, para analizar el estado de avance de esta patología es la radiografía de tórax (RT), aunque en ocasiones esta depende de la experiencia del equipo de salud. Así el objetivo de esta investigación fue explorar la relación de las medidas de mecánica ventilatoria y radiográficas con el tiempo de conexión a VM en pacientes COVID-19. Estudio retrospectivo, que incluyó a 23 pacientes en VM. Se recolectó información de variables de mecánica ventilatoria; PEEP, presión plateau, presión de distensión y compliance estática. Desde la RT se midió, altura y ancho pulmonar, ángulo costodiafragmático y espacio intercostal. Los resultados indicaron que las variables de mecánica ventilatoria tales como el PEEP y el plateau se relacionaron significativamente con el tiempo de conexión a VM (r=0,449; p=0,035 y r=0,472; p=0,026), mientras que las variables radiográficas construidas en base al ángulo costodiafragmático y el espacio intercostal presentaron similares comportamientos (r= 0,462; p=0,046 y r=-0,543; p=0,009). En conclusión, la presión resultante de la programación del ventilador mecánico junto a cambios estructurales observados en la RT, se relacionan con el tiempo de conexión a VM.

SUMMARY: The lungs are the predominant site of COVID-19 infection. This can lead to severe acute respiratory síndrome (ARDS). In view of its severe symptoms, mechanical ventilation (MV) and its ventilatory mechanics values appear as a fundamental tool. Chest radiography (CR) is a complement to analyze the state of progress of this pathology, although this sometimes depends on the experience of the health team. Thus, the aim of this research was to explore the relationship of ventilatory mechanics and radiographic measures with connection time to MV in COVID-19 patients. Retrospective study, which included 23 patients on MV. Information on ventilatory mechanics variables was collected; PEEP, plateau pressure, distension pressure and static compliance. And from CR, lung height and width, costodiaphragmatic angle and intercostal space were measured. The results indicated that ventilatory mechanics variables such as PEEP and plateau were significantly related to connection time to MV (r = 0.449; p = 0.035 and r = 0.472; p = 0.026), while the radiographic variables Constructed on the basis of the costodiaphragmatic angle and the intercostal space, they showed similar behaviors (r = 0.462; p = 0.046 and r = -0.543; p = 0.009). In conclusion, the pressure resulting from mechanical ventilator programming, together with the structural changes observed in CR, are related to the connection time to MV.

Resumen Las escaras (también llamadas úlceras por presión y úlceras de decúbito) son lesiones en la piel y el tejido inferior, resultan de una presión prolongada sobre la misma. En la mayoría de los casos, se manifiestan en la piel que recubre las partes óseas del cuerpo, como talones, tobillos, caderas y coxis. Las personas que corren mayor riesgo de tener escaras tienen limitada su capacidad para cambiar de posición o pasan la mayor parte del tiempo en una cama o una silla de ruedas. Pueden desarrollarse en el transcurso de horas o días, la mayoría se curan con tratamiento, pero algunas nunca se curan completamente. El proceso enfermero es una herramienta metodológica a través del cual Enfermería puede apoyar al paciente y/o familiar en brindar cuidados y educación en la prevención y atención de las úlceras por presión. En México, dos estudios metacéntricos reportan que la prevalencia cruda de UPP es del 12,94% y del 17%, respectivamente. El presente caso se trata de una mujer adulto mayor, en edad extrema (81 años), atendida por su familiar, con regular adherencia a su tratamiento terapéutico y de cuidados, pasa la mayor parte del tiempo en cama, movilización regular aunque con buena higiene, con una escara de región sacra limpia en estadio ll, la paciente y familiar muestra disponibilidad y motivación para aprender acciones de cuidado y prevención adoptar cambios en los hábitos de vida, ser más saludable además mejorar la salud familiar.

Abstract Bedsores (also called pressure ulcers and pressure sores) are lesions on the skin and lower tissue, resulting from prolonged pressure on it. In most cases, they manifest on the skin that covers the bony parts of the body, such as heels, ankles, hips and coccyx. People who are most at risk for bedsores have limited ability to change position or spend most of their time in a bed or wheelchair. They can develop over the course of hours or days, most heal with treatment, but some are never completely cured. The nursing process is a methodological tool through which Nursing can support the patient and / or family in providing care and education in the prevention and care of pressure ulcers. In Mexico, two metacentric studies report that the crude prevalence of PU is 12.94% and 17%, respectively. The present case is about an elderly woman, (81 years), cared for by her relative, with regular adherence to her therapeutic and care treatment, spends most of the time in bed, regular mobilization although with good hygiene, with a clean sacral region eschar in stage II, the patient and family member show availability and motivation to learn care and prevention actions, adopt changes in life habits, be healthier and improve family health.

Resumo Escaras (também chamadas de úlceras de pressão e escaras) são lesões na pele e nos tecidos inferiores, resultantes de pressão prolongada sobre ela. Na maioria dos casos, eles se manifestam na pele que cobre as partes ósseas do corpo, como calcanhares, tornozelos, quadris e cóccix. Pessoas com maior risco de escaras têm capacidade limitada de mudar de posição ou de passar a maior parte do tempo em uma cama ou cadeira de rodas. Eles podem se desenvolver ao longo de horas ou dias, a maioria cura com tratamento, mas alguns nunca estão completamente curados. O processo de enfermagem é uma ferramenta metodológica por meio da qual a Enfermagem pode apoiar o paciente e / ou família na prestação de cuidados e educação na prevenção e cuidado das úlceras por pressão. No México, dois estudos metacêntricos relatam que a prevalência bruta de UP é de 12,94% e 17% 4, respectivamente. O presente caso se refere a uma idosa, em extrema idade (81 anos), cuidada por seu familiar, com adesão regular ao seu tratamento terapêutico e assistencial, passa a maior parte do tempo acamada, mobilização regular, porém, com boa higiene com uma escara limpa da região sacral em estágio II, o paciente e seu familiar demonstram disponibilidade e motivação para aprender ações de cuidado e prevenção, adotar mudanças de hábitos de vida, ter mais saúde e melhorar a saúde da família.

Introducción: Los pacientes con diabetes pueden presentar úlceras por presión, independientemente de generar las propias de esta enfermedad. Sin embargo, aunque está entre las probabilidades, es poco frecuente que se genere una úlcera por presión en la región occipital. Objetivo: Presentar un caso en el que se aplicó la estimulación eléctrica en el tratamiento de una úlcera por presión en la región occipital. Presentación del caso: Paciente chilena de 56 años de edad, con antecedentes de hipertensión arterial y diabetes mellitus, no especificada, con cetoacidosis. Se ingresó en la Unidad de Cuidados Intensivos debido a la presencia de dolor abdominal en el hipocondrio derecho, difuso y levemente asociado con un episodio de vómito, y posteriormente sin dolor, pero con sensación de angustia y disnea. La permanencia en cama, casi sin movilidad alguna, provocó la aparición de una úlcera por presión en la región occipital. A pesar de la aplicación de diferentes métodos convencionales, no se lograba mejoría con el tratamiento, por lo que se determinó la aplicación de la estimulación eléctrica, que se realizó durante 42 días, con una sesión diaria de 30 minutos cada vez. Conclusiones: Después de la aplicación del tratamiento con estimulación eléctrica, se logró la cicatrización de la úlcera por presión(AU)

Introduction: Patients with diabetes can present pressure ulcers, apart from the ones generated by this disease. However, although it is within the possibilities, it is not too frequent that pressure ulcer appears in the occipital area. Objective: To present a case in which it was used electric stimulation in the treatment of a pressure ulcer in the occipital area. Case presentation: 56 years old, Chilean, female patient with a background of arterial hypertension and diabetes mellitus, non specified, and with ketoacidosis. She was admitted in the Intensive Care Unit due to the presence of abdominal pain in the right hipochondrium which was diffuse and slightly associated with a vomiting episode, and later, she had no pain but a feeling of anxiety and respiratory distress. Staying in bed, almost without mobility provoqued the onset of a pressure ulcer in the occipital area. In spite of the use of different conventional methods, there was no improvement with those treatments, so, it was decided to use electric stimulation that was carried out during 42 days with a daily session of 30 minutes each time. Conclusions: After the application of the treatment with electric stimulation, it was achieved the healing of the pressure ulcer(AU)

SUMMARY: This study evaluated the effect of resistance exercise training (RET) on body composition and muscle strength in 16 older women during summer holidays (70.5 ± 8.4 years old; Range 60-87). Exercise sessions were carried out for twelve weeks, two sessions per week, with 60 minutes of exercise per session. We measured body mass index (BMI), fat mass percentage (FM%, by bioimpedance) and grip strength with a dynamometer before and after the intervention. The participants showed a significant increase in BMI (p<0.05), FM% (p<0.001), and a significant gain in grip strength (p<0.05). The RET program could be an important strategy for improving strength for older women, but we would suggest combining it with other interventions, such as aerobic exercises with gradually increasing intensity and nutrition interventions, in order to maintain a steady weight during holiday periods.

RESUMEN: Este estudio evaluó el efecto del entrenamien- to con ejercicios de resistencia (EER) sobre la composición corpo- ral y la fuerza muscular en 16 mujeres adultas mayores durante las vacaciones de verano (70,5 ± 8,4 años; Rango 60-87). Las sesio- nes de ejercicio se llevaron a cabo durante doce semanas, dos ve- ces por semana, con 60 minutos de ejercicio por sesión. Se evaluó el índice de masa corporal (IMC), el porcentaje de masa grasa (% MG, por bioimpedancia) y la fuerza de presión con un dinamómetro manual antes y después de la intervención. Las participantes mos- traron un aumento significativo en el IMC (p< 0,05), % de MG (p<0,001) y un incremento significativo en la fuerza prensil (p <0,05). El programa de EER podría ser una estrategia importante para mejorar la fuerza de mujeres adultas mayores durante el periodo estival. El EER se sugiere combinarlo con otras variables, como ejercicios aeróbicos con intensidad gradualmente creciente y una intervención nutricional, para mantener un peso constante durante los períodos de vacaciones.

O consumo de substâncias psicoativas (SPAs) cresce em escala global, especialmente entre universitários. Este estudo tem como objetivo avaliar o padrão de uso de álcool e outras SPAs em estudantes universitários. A amostra foi composta por 180 graduandos de Psicologia que preencheram um questionário sociodemográfico e instrumentos de rastreamento do uso de SPAs validados para o contexto brasileiro. Os resultados evidenciaram maior prevalência do uso de álcool: 81,7% na vida, 67,6% nos últimos três meses e 55% no padrão binge. Dentre os motivos endossados para o consumo destaca-se o convívio universitário, porém o fator mais valorizado foi o álcool como potencializador do desejo de fumar, seguido de sua percepção como fator gregário em festas/reuniões sociais e como facilitador do enfrentamento de estresse. As pressões da vida universitária geram insegurança e instabilidade que deixam os jovens universitários mais suscetíveis à influência dos pares e à busca de diversão e descontração em ambientes de festas, nas quais o consumo é estimulado e facilitado, o que pode favorecer o beber em quantidade excessiva. Esse padrão de consumo pode se associar a outros comportamentos de risco, como dirigir sob efeito do álcool, manter relações sexuais sem proteção ou envolver-se em distúrbios da ordem pública e infrações à lei. Considerando que os jovens fazem uso em excesso de SPAs sem um suporte social comunitário adequado, é necessário investir em programas de prevenção e políticas públicas guiadas pelas noções de autocuidado, protagonismo e participação ativa na própria reabilitação...(AU)

The consumption of psychoactive substances (SPAs) grows worldwide, especially among university students. This study evaluated the pattern of alcohol use and other SPAs in psychology students. The sample consisted of 180 Psychology undergraduates who filled out a sociodemographic questionnaire and instruments for tracking the use of SPAs validated for the Brazilian context. The results showed a higher prevalence of alcohol use: 81.7% in life, 67.6% in the last three months and 55% following a binge pattern. Among the reasons endorsed for the consumption stand out university conviviality, but the most valued factor was alcohol as a potentiator of the desire to smoke, followed by its perception as a gregarious factor in parties/social gatherings and as a facilitator to cope with stress situations. The pressures of university life create insecurity and instability, which make university students more susceptible to peer influence and the search for fun and relaxation in party environments where drinking is stimulated and facilitated, which may favor binge drinking. This pattern of consumption may be associated to other risk behaviors, such as driving under the influence of alcohol, having unprotected sex, or engaging in public order disturbances and infractions of the law. Considering that these young people make excessive use of SPAs without adequate social and community support, it is necessary to invest in prevention programs and public policies guided by the notions of self-care, protagonism and active participation in self rehabilitation...(AU)

RESUMO A proporção entre pressão venosa central menos arterial de dióxido de carbono e conteúdo de oxigênio arterial menos venoso central (Pcv-aCO2/Ca-cvO2) foi proposta como marcador substituto para quociente respiratório e indicador de oxigenação tissular. Alguns pequenos estudos observacionais identificaram que Pcv-aCO2/Ca-cvO2 acima de 1,4 se associa com hiperlactatemia, dependência de suprimento de oxigênio e maior mortalidade. Mais ainda, a Pcv-aCO2/Ca-cvO2 foi incorporada a algoritmos para avaliação da oxigenação tissular e ressuscitação. Contudo, a evidência para estas recomendações é bastante limitada e de baixa qualidade. O objetivo desta revisão narrativa foi analisar as bases metodológicas, os fundamentos fisiopatológicos e a evidência experimental e clínica para dar suporte à utilização da Pcv-aCO2/Ca-cvO2 como marcador substituto para quociente respiratório. De um ponto de vista fisiopatológico, o aumento do quociente respiratório secundariamente a reduções críticas no transporte de oxigênio é um evento dramático e com risco à vida. Entretanto, este evento é facilmente observável e provavelmente não demandaria maiores monitoramentos. Visto que o início do metabolismo anaeróbico é indicado pelo aumento súbito do quociente respiratório e que a faixa normal do quociente respiratório é ampla, o uso do ponto de corte definido como 1,4 para Pcv-aCO2/Ca-cvO2 não faz sentido. Estudos experimentais demonstraram que a Pcv-aCO2/Ca-cvO2 é mais dependente de fatores que modificam a dissociação do dióxido de carbono da hemoglobina do que do quociente respiratório, e o quociente respiratório e Pcv-aCO2/Ca-cvO2 podem ter comportamentos distintos. Estudos conduzidos em pacientes críticos demonstraram resultados controvertidos com relação à capacidade da Pcv-aCO2/Ca-cvO2 para predizer o desfecho, hiperlactatemia, anomalias microvasculares e dependência de suprimento de oxigênio. Um estudo randomizado controlado também demonstrou que a Pcv-aCO2/Ca-cvO2 é inútil como alvo para ressuscitação. A Pcv-aCO2/Ca-cvO2 deve ser interpretada com cautela em pacientes críticos.

ABSTRACT The central venous minus arterial carbon dioxide pressure to arterial minus central venous oxygen content ratio (Pcv-aCO2/Ca-cvO2) has been proposed as a surrogate for respiratory quotient and an indicator of tissue oxygenation. Some small observational studies have found that a Pcv-aCO2/Ca-cvO2 > 1.4 was associated with hyperlactatemia, oxygen supply dependency, and increased mortality. Moreover, Pcv-aCO2/Ca-cvO2 has been incorporated into algorithms for tissue oxygenation evaluation and resuscitation. However, the evidence for these recommendations is quite limited and of low quality. The goal of this narrative review was to analyze the methodological bases, the pathophysiologic foundations, and the experimental and clinical evidence supporting the use of Pcv-aCO2/Ca-cvO2 as a surrogate for respiratory quotient. Physiologically, the increase in respiratory quotient secondary to critical reductions in oxygen transport is a life-threatening and dramatic event. Nevertheless, this event is easily noticeable and probably does not require further monitoring. Since the beginning of anaerobic metabolism is indicated by the sudden increase in respiratory quotient and the normal range of respiratory quotient is wide, the use of a defined cutoff of 1.4 for Pcv-aCO2/Ca-cvO2 is meaningless. Experimental studies have shown that Pcv-aCO2/Ca-cvO2 is more dependent on factors that modify the dissociation of carbon dioxide from hemoglobin than on respiratory quotient and that respiratory quotient and Pcv-aCO2/Ca-cvO2 may have distinct behaviors. Studies performed in critically ill patients have shown controversial results regarding the ability of Pcv-aCO2/Ca-cvO2 to predict outcome, hyperlactatemia, microvascular abnormalities, and oxygen supply dependency. A randomized controlled trial also showed that Pcv-aCO2/Ca-cvO2 is useless as a goal of resuscitation. Pcv-aCO2/Ca-cvO2 should be carefully interpreted in critically ill patients.

Introducción: En las personas con enfermedad neuromuscular, la incapacidad para toser y para generar flujos espiratorios adecuados constituye el principal limitante para mantener una adecuada salud del sistema respiratorio. La asistencia mecánica de la tos es un dispositivo que genera presión positiva y negativa en la vía aérea y simula una tos normal. Se realizó una revisión bibliográfica. Se incluyeron 9 estudios, con un total de 235 sujetos adultos con enfermedad neuromuscular. Objetivos: Describir los valores de presiones de insuflación y exsuflación utilizados y su relación con los valores de pico flujo tosido. Desarrollo: El 28 por ciento era de género femenino y las edades estaban comprendidas entre 14 a 77 años. Las presiones utilizadas variaron entre los estudios, con valores que iban desde +15/ -15 cm H2O a los +40/ -40 cm H2O. Con respecto a los valores de pico flujo tosido, 7 estudios observaron incrementos estadísticamente significativos al aplicar la terapéutica. En estos estudios, para obtener un flujo espiratorio superior a 160 L/min se requirieron presiones de al menos -30/+30 cm H2O. Conclusiones: Se requieren futuras investigaciones que permitan el desarrollo de un consenso respecto a aplicación de la asistencia mecánica de la tos en sujetos con enfermedad neuromuscular, así como establecer criterios de selección de las presiones de insuflación y exsuflación a programar durante la terapéutica(AU)

Introduction: In people with neuromuscular disease, the inability to cough and generate adequate expiratory flows is the main limitation to maintain adequate health of the respiratory system. The mechanical assistance of the cough is a device that generates positive and negative pressure in the airway, simulating a normal cough. 9 studies were included, with a total of 235 adult subjects with neuromuscular disease. Objectives: Describe the values ​​of insufflation and exsufflation pressures used and to describe their relationship with peak cough flow values. Development: 28 percent were female and the ages between 14 and 77 years old. The pressures used varied between the different studies, with values ​​ranging from + 15 / -15 cm H2O to + 40 / -40 cm H2O. According to the peak cough flow values, seven studies observed statistically significant increases when applying the therapy. In these studies, to obtain an expiratory flow greater than 160 L / min, at least -30 / + 30 cm H2O were required. Conclusions: Future research is required to allow the development of a consensus regarding the application of mechanical cough assistance in subjects with neuromuscular disease, as well as establishing selection criteria for insufflation and exsufflation pressures to be programmed during therapy(AU)

Abstract Introduction Adenoidectomy can be performed with many ways, including curettage and microdebrider endoscopic-assisted adenoidectomy. Those two techniques have advantages and disadvantages. Objective The objective of this study is to research the effects of curettage adenoidectomy and endoscopic-assisted microdebrider adenoidectomy on the tympanum pressures in pediatric patients with adenoid hypertrophy without otitis media with effusion. Methods This prospective descriptive study was performed with 65 patients who had a normal tympanic membrane and normal tympanogram and then underwent adenoidectomy or adenotonsillectomy for adenoid and tonsil hypertrophy. The subjects were randomly divided into two groups: curettage adenoidectomy group and endoscopic microdebrider-assisted adenoidectomy group. They underwent tympanometry, and the preoperative as well as 1st and 7th day postoperative values of the tympanum pressures were compared within and among the groups. Results There were 32 patients in the curettage adenoidectomy group and 33 patients in the microdebrider adenoidectomy group. Statistically significant differences were observed in the median tympanum pressure on the preoperative and 1st and 7th postoperative days for both the left and right ears with curettage adenoidectomy (p < 0.001, p < 0.001). This difference occurred on the 1st postoperative day, and the value returned to normal on the 7th day. There was no significant difference in the median tympanum pressure on the preoperative and 1st and 7th postoperative days for both the left and right ears in the microdebrider adenoidectomy group (p = 0.376, p = 0.128). Conclusion Postoperative Eustachian tube dysfunction is seen less often with the endoscopic-assisted microdebrider adenoidectomy technique than with the conventional adenoidectomy technique.

Resumo Introdução A adenoidectomia pode ser realizada de várias maneiras, inclusive por curetagem e por microdebridador, assistida por endoscopia. Essas duas técnicas têm algumas vantagens e desvantagens. Objetivo O objetivo deste estudo foi investigar os efeitos da técnica de adenoidectomia por curetagem e da adenoidectomia por microdebridador assistida por endoscopia sobre a pressão timpânica em pacientes pediátricos com hipertrofia adenoideana sem otite média com efusão. Método Estudo descritivo prospectivo feito com 65 pacientes que apresentavam membrana timpânica e timpanograma normais, que foram então submetidos à adenoidectomia ou adenotonsilectomia por hipertrofia adenoamigdaliana. Os pacientes foram divididos aleatoriamente em dois grupos: grupo adenoidectomia por curetagem e grupo adenoidectomia por microdebridador assistida por endoscópio. Todos os pacientes fizeram timpanometria e os valores das pressões do tímpano pré-operatórios e pós-operatórios no 1º e 7º dias foram comparados intragrupos e entre os grupos. Resultados Foram incluídos 32 pacientes no grupo adenoidectomia por curetagem e 33 pacientes no grupo adenoidectomia com microdebridador. Diferenças estatisticamente significantes foram observadas na mediana da diferença entre a pressão timpânica no pré-operatório e no 1º e 7º dias de pós-operatório para ambas as orelhas, direita e esquerda, na adenoidectomia por curetagem (p < 0,001, p < 0,001). Essa diferença ocorreu no 1º dia do pós-operatório e o valor retornou ao normal no 7º dia. Não houve diferença significante na mediana entre pressão timpânica no pré-operatório e no 1º e 7º dias de pós-operatório para as orelhas direita e esquerda no grupo de adenoidectomia com microdebridador (p = 0,376, p = 0,128). Conclusão A disfunção tubária no pós-operatório é observada menos frequentemente com a técnica de adenoidectomia por microdebridador assistida por endoscopia quando comparada com a técnica convencional.
