Efeito do tônus do corpo perineal nas disfunçõessexuais em mulheres jovens nulíparas / Effect of perineal body tone on sexual dysfunctionsin young nulliparous women

Objetivo: avaliar o tônus do corpo perineal em mulheres jovens nulíparas e correlacionar com as funções sexuais e a presença de disfunção sexual. Método: foi realizado um estudo descritivo, observacional, transversal utilizando uma amostra de conveniência incluindo mulheres adultas jovens nulíparas. A avaliação das participantes consistiu na aplicação dos questionários socioclínico, Pelvic Organ Prolaps / Urinary Incontinence Sexual Questionnaire (PISQ-12), Female Sexual Function Index (FSFI) e exame físico do tônus do corpo perineal. Os dados foram analisados pelo programa Statistical Package for the Social Sciences (SPSS®), versão 23, adotando um nível de significância de 5%. Resultados: participaram 77 mulheres jovens nulíparas (21,68 ± 2,94 anos), destas 77, 92% apresentavam vida sexual ativa e 66,03% tônus normal do corpo perineal. Dentre as alterações tônicas, o aumento do tônus predominou (33,76%). Houve alta prevalência de disfunção sexual (87,01%) pelo FSFI (23,38 ± 7,21) com maior queixa de dispareunia. Mulheres com tônus aumentado apresentaram maior disfunção sexual em relação a desejo e estímulo subjetivo (p=0,04), à excitação (p=0,01), satisfação (p=0,04) e dor ou a desconforto (p=0,03). Houve correlação inversa entre a presença de aumento do tônus e os domínios FSFI desejo e estímulo subjetivo (R= - 0,56) e excitação (R= - 0,34) e correlação direta para dor ou desconforto (R= 0,30). Conclusão: o aumento do tônus do corpo perineal piora a função sexual de mulheres jovens nulíparas.

Sexual Function Index (FSFI) and physical examination of the tone of the perineal body. The data were analyzed using the Statistical Package for the Social Sciences (SPSS®), version 23, adopting a significance level of 5%. Results: 77 young nulliparous women (21.68 ± 2.94 years) participated, of which 77, 92% had an active sexual life and 66.03% had normal tone of the perineal body. Among the tonic changes, increased tone predominated (33.76%). There was a high prevalence of sexual dysfunction (87.01%) according to the FSFI (23.38 ± 7.21) with greater complaints of dyspareunia. Women with increased tone had greater sexual dysfunction in relation to desire and subjective stimulation (p=0.04), excitement (p=0.01), satisfaction (p=0.04) and pain or discomfort (p=0.03). There was an inverse correlation between the presence of increased tone and the FSFI domains desire and subjective stimulus (R= - 0.56) and excitement (R= - 0.34) and a direct correlation for pain or discomfort (R= 0.30). Conclusion: increased perineal body tone worsens sexual function in young nulliparous women.

Impacto da fisioterapia aquática em UTIN sobre a mobilidade diafragmática avaliada por ultrassonografia cinesiológica: ensaio clínico / Impact of Aquatic Therapy in the NICU on diaphragmatic mobility assessed by ultrasound: clinical trial

INTRODUÇÃO: A fisioterapia aquática é uma modalidade de hidroterapia realizada em recém-nascidos (RN) nas Unidades de Terapia Intensiva Neonatal (UTIN). Os efeitos sobre nível de dor, estado comportamental e função respiratória já são conhecidos, porém pouco se refere aos efeitos sobre a função diafragmática na população recém-nascida a termo prematura. OBJETIVO: Avaliar o efeito da fisioterapia aquática sobre a amplitude diafragmática por meio da ultrassonografia cinesiológica diafragmática (USCD) em RNs internados em UTIN, bem como a segurança de sua realização quanto a estabilidade clínica dos RNs, estado comportamental, dor e desconforto respiratório. MÉTODOS: Ensaio clínico tipo antes e depois, de caráter transversal. Os RNs participantes do estudo receberam uma única intervenção com fisioterapia aquática durante 10 minutos. Foi realizada a avaliação utilizando a USCD antes e depois da sessão, e anotado as frequências cardíaca e respiratória, estado comportamental, dor e desconforto respiratório. RESULTADOS: Participaram 26 RNs. Observou-se aumento significativo da amplitude diafragmática (p= 0,02) e da saturação periférica de oxigênio (p= 0,05); os parâmetros fisiológicos permaneceram nos limites da normalidade e a intervenção não provocou desorganização comportamental, dor ou desconforto respiratório aos RNs. CONCLUSÃO: A fisioterapia aquática promoveu aumento da amplitude diafragmática, sugerindo que esta técnica pode ser utilizada como forma de estimular a contração da musculatura respiratória em RN, além de se mostrar uma técnica segura, pois não gerou instabilidade clínica, desorganização comportamental, dor ou desconforto respiratório aos participantes.

INTRODUCTION: Aquatic physiotherapy is a modality of hydrotherapy performed on newborn babies (NB) in the Neonatal Intensive Care Unit (NICU). The effects on pain levels, behavior, and respiratory function are already known; however, little has been said about the effects on diaphragmatic function in the preterm newborn population. OBJECTIVE: To evaluate the effect of aquatic physiotherapy on diaphragmatic amplitude using diaphragmatic kinesiologic ultrasound (DKUS) in NBs admitted to a NICU, as well as the safety regarding the clinical stability of the NBs, behavioral state, pain, and respiratory distress. METHODS: Crosssectional before-and-after clinical trial. The NBs participating in the study received a single intervention with aquatic physiotherapy for 10 minutes. An assessment was performed using the USCD before and after the session, and heart and respiratory rates, behavioral state, pain, and respiratory discomfort were recorded. RESULTS: Twenty-six NBs participated. There was a significant increase in diaphragmatic amplitude (p= 0.02) and peripheral oxygen saturation (p= 0.05); physiological parameters remained within normal limits, and the intervention did not cause behavioral disorganization, pain, or respiratory discomfort in NBs. CONCLUSION: Aquatic physiotherapy promoted an increase in diaphragmatic amplitude, suggesting that this technique can be used as a way to stimulate the contraction of the respiratory muscles in NB, in addition to being a safe technique, as it did not generate clinical instability, behavioral disorganization, pain, or respiratory discomfort to the participants.

Association between nutritional risk status and both diaphragmatic dysfunction and diaphragm atrophy in medical intensive care unit patients.

Introduction: Aim: critical illness often leads to malnutrition and diaphragmatic dysfunction (DD), common in intensive care units (ICU). Ultrasonography (US) is a potent tool for detecting DD. This study examines the connection between malnutrition risk and DD in ICU patients using ultrasonographic diaphragm measurements in medical ICU patients. Methods: we assessed nutritional risk using risk screening tools and mid-upper arm circumference measurements (MUAC). Diaphragm atrophy (DA) and DD were evaluated by measuring diaphragmatic excursion (DE), thickness, and thickening fraction (TF) by US. We then compared these diaphragmatic measurements in patients based on their nutritional risk scores. Results: of the fifty patients studied, 54 % to 78 % were at risk of malnutrition, 28 % exhibited diaphragm atrophy (DA), and 24 % showed DD upon ICU admission. Malnutrition risk diagnosed by all nutritional risk screening tools was significantly more frequent in patients with DD, while diagnosed by MUAC was considerably higher in patients with DA. A total of 16 patients (32 %) died during their ICU stay, with DD, DA, and malnutrition risks (as identified by the mNUTRIC Score) being more prevalent among non-survivors (p < 0.05). Malnutrition risk (as determined by the mNUTRIC Score) was an independent risk factor for DD [OR (95 % CI): 6.6 (1.3-34), p = 0.03]. Conclusion: malnutrition risk may be significantly associated with DD and DA in medical ICU patients upon ICU admission.

Introducción: Objetivo: las enfermedades graves a menudo conducen a desnutrición y disfunción diafragmática (DD), comunes en las unidades de cuidados intensivos (UCI). La ultrasonografía (US) es una herramienta poderosa para detectar la DD. Este estudio examina la conexión entre riesgo de desnutrición y DD en pacientes de UCI utilizando mediciones ultrasonográficas del diafragma. Métodos: evaluamos el riesgo nutricional utilizando herramientas de evaluación de riesgos y mediciones de la circunferencia del brazo en su punto medio superior (MUAC). La atrofia del diafragma (DA) y la DD se evaluaron midiendo la excursión diafragmática (DE), el grosor y la fracción de engrosamiento (TF) por ecografía. Luego, comparamos estas mediciones diafragmáticas en pacientes según sus puntuaciones de riesgo nutricional. Resultados: de los cincuenta pacientes estudiados, entre el 54 % y el 78 % estaban en riesgo de desnutrición, el 28 % presentaban atrofia del diafragma (DA) y el 24 % mostraban DD al ingreso en la UCI. El riesgo de desnutrición diagnosticado por todas las herramientas de evaluación del riesgo nutricional fue significativamente más frecuente en los pacientes con DD, mientras que el diagnosticado por el MUAC fue considerablemente mayor en los pacientes con DA. Un total de 16 pacientes (32 %) fallecieron durante su estancia en la UCI, siendo la DD, la DA y los riesgos de desnutrición (según lo identificado por la puntuación mNUTRIC) más prevalentes entre los no sobrevivientes (p < 0,05). El riesgo de desnutrición (según lo determinado por la puntuación mNUTRIC) fue un factor de riesgo independiente de la DD [OR (95 % CI): 6,6 (1,3-34), p = 0,03]. Conclusión: en este estudio se encontró una asociación significativa entre el riesgo de desnutrición y la disfunción diafragmática, así como con la atrofia diafragmática al ingreso en la UCI.

Diaphragmatic and excursion thickness in newborns using diaphragmatic kinesiology ultrasound: an observational study / Espessura e excursão diafragmática em recém-nascidos usando ultrassonografia cinesiológica do diafragma: um estudo observacional

Abstract Introduction The study of the diaphragm muscle has aroused the interest of physiotherapists who work with kinesiological ultrasonography, but still little explored; however, its findings can contribute to the clinical practice of hospitalized patients in neonatal intensive care units. Objective To measure the excursion and thickening of the diaphragm and describe measurements among neonates, preterm, and full-term. Methods Diaphragmatic kinesiological ultrasonography was performed on hospitalized newborns, in Neonatal Unit Care Unit, placed in supine position in their own bed, on the sixth day of life. Three repeated measurements of the same respiratory cycle were made, both for excursion and for diaphragmatic thickening. Results 37 newborns participated in the study and 25 were premature. The mean weight at the time of collection was 2,307.0 ± 672.76 grams and the gestational age was 35.7 ± 3.3 weeks. Diaphragmatic excursion increased with increasing gestational age (p = 0.01, df = 0.21) in term infants (p = 0.17, df = 0.35). Conclusion There was a positive correlation between diaphragmatic excursion and gestational age. There was no statistically significant difference in the measurements of excursion and inspiratory diaphragm thickening between preterm and term newborns, although pointing to higher measurements in the latter group.

Resumo Introdução O estudo do músculo diafragma tem des-pertado o interesse dos fisioterapeutas que trabalham com ultrassonografia cinesiológica. Ainda pouco explo-rado, contudo, seus achados podem contribuir para a prática clínica dos pacientes internados em unidades de terapia intensiva neonatal (UTIN). Objetivo Mensurar a excursão e o espessamento diafragmático e descrever as medidas entre recém-nascidos prematuros e a termo. Métodos Realizou-se ultrassonografia cinesiológica diafragmática em recém-nascidos internados em UTIN, posicionados em supino em seu próprio leito, no sexto dia de vida. Foram realizadas três medidas repetidas do mesmo ciclo respiratório, tanto da excursão quanto do espessamento diafragmático. Resultados Participaram do estudo 37 recém-nascidos, dos quais 25 eram pre-maturos. O peso no momento da coleta foi de 2.307,0 ± 672,76 gramas e a idade gestacional foi de 35,7 ± 3,3 semanas. A excursão diafragmática aumentou de acordo com o aumento da idade gestacional (p = 0,01; df = 0,21). A espessura variou entre 0,10 e 0,16 cm durante a inspiração nos prematuros e entre 0,11 e 0,19 cm nos nascidos a termo (p = 0,17; df = 0,35). Conclusão Houve correlação positiva entre a excursão diafragmá-tica e a idade gestacional. Não observou-se diferença estatisticamente significativa das medidas de excursão e de espessamento diafragmático inspiratório entre recém-nascidos prematuros e recém-nascidos a termo, embora apontando para maiores medidas neste último grupo.

Medición de la fuerza muscular en adultos como predictor de extubación en Unidades de Cuidados Intensivos. Revisión narrativa / Measurement of muscular strength in adults as a predicator of extubation in intensive care units. Narrative review

Resumen: Introducción: uno de los principales efectos de la ventilación mecánica invasiva es la lesión de los músculos respiratorios, específicamente, sobre el diafragma en el que pueden ocurrir alteraciones estructurales y funcionales que modifican parcial o totalmente su función. Durante la ventilación mecánica se produce un proceso de atrofia por desuso de dicho músculo. Por ello la utilidad clínica de la medición de la fuerza muscular diafragmática es importante para conocer si el paciente tiene la capacidad de activar los mecanismos protectores de la vía aérea para lograr la extubación exitosa y el retiro del ventilador mecánico en el menor tiempo posible. Objetivos: describir la medición de la fuerza muscular como predictor de la extubación en las unidades de cuidados intensivos. Material y métodos: se realizó una revisión de la literatura, entre 2011 y 2022. Resultados: los pacientes que son sometidos a ventilación mecánica invasiva prolongada generalmente desarrollan una afección muscular diafragmática, lo que se convierte en una problemática para el proceso de extubación temprana, por lo cual es vital conocer los métodos de medición de fuerza muscular como predictor de extubación.

Monitorización avanzada durante la desvinculación de la ventilación mecánica invasiva en el trasplante unipulmonar / Advanced monitoring during weaning of invasive me chanical ventilation in single-lung transplantation

Resumen El trasplante de pulmón bilateral es el tratamiento de las enfermedades pulmonares en su etapa terminal. Sin embargo, a veces se realiza el trasplante de un solo pulmón. La técnica no está exenta de complicaciones como la hiperinsuflación aguda del pulmón nativo y cambios en el diafragma, predisponiendo a atelectasias e insuficiencia respiratoria que pueden derivar en resul tados negativos. Por lo tanto, las pruebas de respiración espontánea pueden fallar y retrasar el proceso de des vinculación de la ventilación mecánica. La combinación de herramientas de monitorización avanzadas, como la tomografía por impedancia eléctrica y la ecografía, para diagnosticar la causa de este fallo, reconociendo y cuantificando la distribución del volumen pulmonar y su comportamiento dinámico, podría ser crucial para mejorar los resultados. Presentamos el caso de un paciente con trasplante unipulmonar y ventilación prolongada que falla en repetidas ocasiones durante la desvinculación de la ventilación mecánica, donde utilizamos herramientas de monitoreo avanzado para detectar la causa de la falla.

Abstract Bilateral lung transplantation is the treatment of end-stage lung diseases. However, sometimes a single lung transplant is performed. The technique is not exempt from complications such as acute hyperinfla tion of the native lung and changes in the diaphragm, predisposing to atelectasis and respiratory failure that can lead to negative results. Therefore, spontaneous breathing trials may fail and delay the weaning process. The combination of advanced monitoring tools, such as electrical impedance tomography and ultrasonography, to diagnose the cause of this failure, recognizing and quantifying the distribution of lung volume and its dynamic behavior could be crucial to improve outcomes. We present the case of a patient with a one-lung transplant and prolonged mechanical ventilation who, after presenting successive failures in the weaning pro cess, underwent advanced monitoring in order to find the causes of the failure.

Al examen físico, se auscultan ruidos cardíacos en el hemitórax derecho y la radiografía de tórax evidencia dextrocardia e imagen que semeja masa supra diafragmática derecha, la TAC trifásica confirma la presencia de protrusión de un segmento del hígado de forma redondeada a través de un defecto no abierto del hemidiafragma derecho. Su tratamiento ha sido conservador. Conclusión: la combinación de dextrocardia acompañada de herniación de una porción del hígado a través de un defecto del diafragma derecho es una asociación extremadamente rara y los reportes de caso publicados son escasos

Influence of mild pulmonary congestion on diaphragmatic mobility and activities of daily living in chronic kidney disease: An experimental and clinical study.

BACKGROUND: Pulmonary congestion is a strong predictor of mortality and cardiovascular events in chronic kidney disease (CKD); however, the effects of the mild form on functionality have not yet been investigated. The objective of this study was to assess the influence of mild pulmonary congestion on diaphragmatic mobility (DM) and activities of daily living (ADL) in hemodialysis (HD) subjects, as well as compare ADL behavior on dialysis and non-dialysis days. In parallel, experimentally induce CKD in mice and analyze the resulting pulmonary and functional repercussions. METHODS: Thirty subjects in HD underwent thoracic and abdominal ultrasonography, anthropometric assessment, lung and kidney function, respiratory muscle strength assessment and symptoms analysis. To measure ADL a triaxial accelerometer was used over seven consecutive days. Twenty male mice were randomized in Control and CKD group. Thoracic ultrasonography, TNF-α analysis in kidney and lung tissue, exploratory behavior and functionality assessments were performed. RESULTS: Mild pulmonary congestion caused a 26.1% decline in DM (R2=.261; P=.004) and 20% reduction in walking time (R2=.200; P=.01), indicating decreases of 2.23mm and 1.54min, respectively, for every unit increase in lung comet-tails. Regarding ADL, subjects exhibited statistically significant differences for standing (P=.002), walking (P=.034) and active time (P=.002), and number of steps taken (P=.01) on days with and without HD. In the experimental model, CKD resulted in increased levels of TNF-α on kidneys (P=.037) and lungs (P=.02), attenuation of exploratory behavior (P=.01) and significant decrease in traveled distance (P=.034). Thoracic ultrasonography of CKD mice showed presence of B-lines. CONCLUSION: The mild pulmonary congestion reduced DM and walking time in subjects undergoing HD. Individuals were less active on dialysis days. Furthermore, the experimental model implies that the presence of pulmonary congestion and inflammation may play a decisive role in the low physical and exploratory performance of CKD mice.

Diaphragm ultrasound after manual rib cage stabilization maneuver in premature newborns: clinical trial / Ultrassom diafragmático após manobra de estabilização costal manual em recém-nascidos prematuros: ensaio clínico

Abstract Introduction The manual rib cage stabilization maneu-ver (MRCSM) is a physical therapy intervention that promotes stabilization of the zone of apposition of the diaphragm, facilitating the contraction of this muscle and the work of breathing. Objective To evaluate by diaphragm ultrasound the diaphragmatic excursion in premature newborns before and after MRCSM. Methods Before-after clinical trial assessing by diaphragm ultra-sound the effectiveness of MRCSM in the amplitude of diaphragmatic excursions. Results The study sample consisted of 48 premature newborns born at a mean gestational age of 33.0 ± 2.8 weeks with a mean birth weight of 1,904.1 ± 708.9 grams. The newborns were classified in three groups: without respiratory distress syndrome (RDS; n = 26), with RDS (n = 15) and with apnea (n = 7) as a cause of admission to the neonatal intensive care unit (NICU). The measurements of diaphragmatic excursion and thickening were similar in newborns without or with RDS or apnea and there was a significant increase in the amplitude of diaphragmatic excursions after MRCSM (p < 0.001; effect size > 0.68) and less diaphragmatic thickening at exhalation in all of them. The diaphragm thickening fraction was 0.50 (0.33 - 0.72), and the diaphragm thickening rate was 0.04 (0.03 - 0.07). These measurements showed no significant variation with the presence or absence of RDS or apnea (p > 0.05). No significant variations in heart rate (p = 0.30), respiratory rate (p = 0.79), and peripheral oxygen saturation, consid-ering newborns in ambient air (p = 0.17) compared with baseline. Conclusion The MRCSM was effective, safe, and increased the amplitude of diaphragmatic excursion and thickness in premature newborns at one week of age, regardless of the presence or absence of RDS or apnea as a cause of admission to the NICU.

Resumo Introducão A manobra manual de estabilização da caixa torácica (MRCSM) é uma intervenção fisioterapêutica que promove a estabilização da zona de aposição do diafragma, facilitando a contração deste músculo e o trabalho respiratório. Objetivo Avaliar pela ultrassonografia do diafragma a excur-são diafragmática em recém-nascidos prematuros antes e após MRCSM. Métodos Ensaio clínico antes e depois avaliando por ultrassonografia do diafragma a eficácia do MRCSM na amplitude das excursões diafragmáticas. Resultados A amos-tra do estudo foi composta por 48 recém-nascidos prematuros nascidos com idade gestacional média de 33,0 ± 2,8 semanas e peso médio ao nascer de 1904,1 ± 708,9 gramas. Os recém-nascidos foram classificados em três grupos: sem síndrome do desconforto respiratório (SDR; n = 26), com SDR (n = 15) e com apneia (n = 7) como causa de internação na unidade de terapia intensiva neonatal (UTIN) . As medidas de excursão e espessamento diafragmático foram semelhantes em recém-nascidos sem ou com SDR ou apneia e houve aumento significativo na amplitude das excursões diafragmáticas após MRCSM (p < 0,001; tamanho de efeito > 0,68) e menor espes-samento diafragmático na expiração em todos eles. A fração de espessamento do diafragma foi de 0,50 (0,33 - 0,72) e a taxa de espessamento do diafragma foi de 0,04 (0,03 - 0,07). Essas medidas não apresentaram variação significativa com a presença ou ausência de SDR ou apneia (p > 0,05). Não houve variações significativas na frequência cardíaca (p = 0,30), frequência respiratória (p = 0,79), saturação periférica de oxigênio, considerando os recém-nascidos em ar ambiente (p = 0,17) em comparação com o valor basal. Conclusão O MRCSM foi eficaz, seguro e aumentou a amplitude da excursão e espessura diafragmática em recém-nascidos prematuros com uma semana de idade, independentemente da presença ou ausência de SDR ou apneia como causa de admissão na UTIN.

Effects of COVID-19 on diaphragm thickness and physical performance of athletes / Efeitos da COVID-19 na espessura diafragmática e desempenho físico de atletas

Abstract Introduction Studies suggest that diaphragm thickness (DT) is associated with inspiratory muscle strength and consequently, better ventilatory and mechanical efficiency. On the other hand, infectious diseases such as COVID-19 may impact the structure and function of the respiratory system. Objective Assess the association between DT and the physical performance (PP) of athletes and the effects of COVID-19 infection on these parameters. Methods This is a cross-sectional study of 63 athletes of both sexes from different sport modalities (women: 16.67 ± 5.03 years, 52.09 ± 14.01 kg, 155.90 ± 13.86 cm; men: 23.44 ± 9.65 years, 72.24 ± 14.18 kg, 174.84 ± 6.84 cm), submitted to DT assessment using ultrasound, followed by the PP(Yo-Yo) test) to determine maximum oxygen intake (VO2max). Pearson's correlation was used to determine the association between VO2max and DT, and the Student's t-test for differences between athletes with a positive and negative diagnosis for COVID-19. The significance level was set at 5%. Results There was no association between DT and PP (r = 0.30 and p = 0.22) or between athletes unaffected and affected by COVID-19 in relation to DT (57.00 ± 0.26 vs 52.00 ± 0.25%; p = 0.91) and PP (43.88 ± 2.29 vs 38.34 ± 13.61 ml/kg/min; p = 0.69). Conclusion DT was not associated with maximum oxygen intake in athletes. In addition, athletes infected by COVID-19 exhibited no differences in VO2max or DT when compared to nonaffected individuals.

Resumo Introdução Estudos sugerem que a espessura diafrag-mática (ED) está associada à força muscular inspiratória e, consequentemente, à melhor eficiência ventilatória e mecânica. Por outro lado, doenças infecciosas como a COVID-19 podem impactar a estrutura e função do apa-relho respiratório. Objetivo Avaliar a associação entre a ED e o desempenho físico (DF) de atletas e os efeitos da infecção por COVID-19 sobre esses parâmetros. Métodos Trata-se de um estudo transversal envolvendo 63 atletas de diferentes modalidades esportivas, de ambos os sexos (feminino: 16,67 ± 5,03 anos, 52,09 ± 14,01 kg, 155,90 ± 13,86 cm; masculino 23,44 ± 9,65 anos, 72,24 ± 14,18 kg, 174,84 ± 6,84 cm), que foram submetidos à avaliação da ED por meio de ultrassom e, em seguida, ao teste de DF (Yo-Yo test) para determinar o consumo máximo de oxigênio (VO2max). Utilizou-se a correlação de Pearson para verificar a associação entre VO2max e ED, e o teste t de Student para diferenças entre atletas com diagnóstico positivo e negativo para COVID-19. O nível de significância foi ajustado em 5%. Resultados Não houve associação entre ED e DF (r = 0,30 e p = 0,22) e não houve diferença entre os atletas não infectados e infectados por COVID-19 em relação à ED (57,00 ± 0,26 vs 52,00 ± 0,25%; p = 0,91) e DF (43,88 ± 2,29 vs 38,34 ± 13,61 ml/kg/min; p = 0,69). Conclusão A ED não foi associada ao consumo máximo de oxigênio em atletas. Além disso, atletas infectados por COVID-19 não exibiram diferenças no VO2max e ED em relação aos não infectados.

Hernia diafragmática traumática derecha en paciente geriátrico. Reporte de un caso infrecuente / Traumatic right diaphragmatic hernia in an elderly patient. A rare case report

Introducción: La hernia diafragmática surge como resultado del movimiento de los órganos abdominales hacia el tórax a través de un defecto del diafragma resultante de varios tipos de lesiones, que a menudo representan un desafío diagnóstico y terapéutico. La hernia diafragmática traumática es una enfermedad infrecuente. El trauma diafragmático rara vez es aislado, la mayoría de las veces se acompaña de otras lesiones toracoabdominales, cerebrales o musculoesqueléticas, siendo estas comorbilidades más graves responsables del mal pronóstico y aumento de la mortalidad. Caso clínico: Anciana de 90 años de edad, hipertensa, quien inicia cuadro clínico 48 horas previas a su ingreso, cuando posterior a caída del plano de bipedestación presenta disminución del estado de consciencia, náuseas, vómitos y disnea en reposo. Rx de tórax evidencia asas intestinales en hemitórax derecho. Se realizó laparotomía exploradora. Conclusión: Las hernias diafragmáticas traumáticas son infrecuentes, con incidencia <3%, sintomatología inespecífica y relacionadas generalmente con lesiones asociadas al trauma. Siempre se debe sospechar de una HD ante un paciente con antecedente de trauma cerrado de alto impacto o penetrante, en función de la cinética y mecanismo de lesión. El diagnóstico supone un reto para el cirujano, debiendo apoyarse en una firme sospecha y estudios radiológicos. Su tratamiento es quirúrgico, debiendo ser individualizado, con abordajes torácicos o abdominales en función del caso. La técnica a emplear dependerá de las características del defecto, de la fase del diagnóstico y la experiencia del equipo quirúrgico(AU)

Introduction: Diaphragmatic hernia arises as a result of the movement of the abdominal organs towards the thorax through a defect in the diaphragm resulting from various types of injuries, which often represent a diagnostic and therapeutic challenge. Traumatic diaphragmatic hernia is a rare disease. Diaphragmatic trauma is rarely isolated, most of the time it is accompanied by other thoracoabdominal, brain or musculoskeletal injuries, these more serious comorbidities being responsible for the poor prognosis and increased mortality. Clinical case: A 90-year-old woman with hypertension , who began a clinical picture 48 hours prior to admission, when after falling from the standing plane he presented a decreased state of consciousness, nausea, vomiting, and dyspnea at rest. Chest x-ray shows intestinal loops in the right hemithorax. Exploratory laparotomy was performed. Conclusion: Traumatic diaphragmatic hernias are rare, with an incidence of <3%, non-specific symptoms, and generally related to injuries associated with trauma. HD should always be suspected in a patient with a history of high-impact or penetrating blunt trauma, depending on the kinetics and mechanism of injury. Diagnosis is a challenge for the surgeon, and must be based on a firm suspicion and radiological studies. Its treatment is surgical, and must be individualized, with thoracic or abdominal approaches depending on the case. The technique to be used will depend on the characteristics of the defect, the diagnostic phase and the experience of the surgical team(AU)

Ventilación mecánica de protección pulmonar y diafragmática en terapia intensiva / Mechanical ventilation for lung and diaphragm protection in intensive care / Ventilação mecânica para proteção pulmonar e diafragmática em terapia intensiva

Resumen: El enfermo crítico con ventilación mecánica presenta múltiples cambios deletéreos en la estructura y función del diafragma, denominados colectivamente disfunción diafragmática inducida por ventilador. Existen cuatro posibles mecanismos de miotrauma diafragmático: sobreasistencia ventilatoria, baja asistencia ventilatoria, miotrauma excéntrico y miotrauma espiratorio; los procesos moleculares y celulares subyacentes incluyen disfunción metabólica, estrés oxidativo mitocondrial y desequilibrio en la homeostasis proteica que culmina en atrofia diafragmática. La creciente comprensión en los mecanismos del miotrauma diafragmático, lesión pulmonar inducida por ventilador y lesión pulmonar autoinfligida da pie a un enfoque de ventilación mecánica en terapia intensiva que integre medidas de protección pulmonar y diafragmática: drive respiratorio, esfuerzo respiratorio, presión transpulmonar, presión intraabdominal, presión positiva al final de la espiración, manejo de asincronías, oxigenación y analgesia-sedación, además de considerar el tratamiento médico de las condiciones concurrentes con el objetivo de favorecer la liberación de la ventilación mecánica (VM), prevenir la discapacidad a largo plazo y aumentar la supervivencia, así como fomentar futuras investigaciones para la implementación en el entorno clínico.

Abstract: Critically ill patients with mechanical ventilation present multiple deleterious changes in the structure and function of the diaphragm, collectively called ventilator-induced diaphragmatic dysfunction. There are four possible mechanisms of diaphragmatic myotrauma: ventilatory over-assistance, low ventilatory assistance, eccentric myotrauma and expiratory myotrauma; underlying molecular and cellular processes include metabolic dysfunction, mitochondrial oxidative stress, and imbalance in protein homeostasis culminating in diaphragmatic atrophy. The growing understanding of the mechanisms of diaphragmatic myotrauma, ventilator-induced pulmonary injury and self-inflicted pulmonary injury gives rise to a mechanical ventilation approach in intensive care that integrates pulmonary and diaphragmatic protection measures: Respiratory drive, respiratory effort, transpulmonary pressure, intraabdominal pressure , positive end-expiratory pressure, management of asynchronies, oxygenation and analgesia-sedation, in addition to considering the medical treatment of concurrent conditions, with the aim of favoring the release of MV, preventing long-term disability and increasing the survival, as well as encourage future research for implementation in the clinical setting.

Resumo: O paciente em estado grave com ventilação mecânica apresenta múltiplas alterações deletérias na estrutura e função do diafragma, denominadas coletivamente como disfunção diafragmática induzida pelo ventilador. Existem quatro mecanismos possíveis de miotrauma diafragmático: sobrecarga ventilatória, baixo suporte ventilatório, miotrauma excêntrico e miotrauma expiratório; processos moleculares e celulares subjacentes incluem disfunção metabólica, estresse oxidativo mitocondrial e desequilíbrio na homeostase proteica culminando na atrofia diafragmática. A crescente compreensão dos mecanismos de miotrauma diafragmático, lesão pulmonar induzida por ventilador e lesão pulmonar autoinfligida dá origem a uma abordagem de ventilação mecânica em Terapia Intensiva que integra medidas de proteção pulmonar e diafragmática: drive respiratório, esforço respiratório, pressão transpulmonar, intra-pressão abdominal, pressão positiva ao final da expiração, manejo da assincronia, oxigenação e analgesia-sedação, além de considerar o tratamento médico das condições concomitantes, com o objetivo de favorecer a liberação da VM, prevenir incapacidades a longo prazo e aumentar a sobrevivência, bem como encorajar pesquisas futuras para implementação no ambiente clínico.

Associação entre área de secção transversa do reto femoral e excursão diafragmática com o desmame de pacientes com traqueostomia na unidade de terapia intensiva / Association between rectus femoris cross-sectional area and diaphragmatic excursion with weaning of tracheostomized patients in the intensive care unit

RESUMO Objetivo: Verificar a relação entre área de secção transversa do reto femoral e excursão diafragmática com sucesso no desmame da ventilação mecânica em pacientes críticos crônicos com traqueostomia. Métodos: Este foi um estudo de coorte observacional prospectivo. Incluímos pacientes críticos crônicos (aqueles submetidos à colocação de traqueostomia após 10 dias de ventilação mecânica). A área de secção transversa do reto femoral e a excursão diafragmática foram obtidas por ultrassonografia realizada dentro das primeiras 48 horas após a traqueostomia. Medimos a área de secção transversa do reto femoral e a excursão diafragmática para avaliar sua associação com o desmame da ventilação mecânica, incluindo sua capacidade de prever o sucesso no desmame e a sobrevida durante toda a internação na unidade de terapia intensiva. Resultados: Foram incluídos 81 pacientes. Quarenta e cinco pacientes (55%) foram desmamados da ventilação mecânica. A mortalidade foi de 42% e 61,7% na unidade de terapia intensiva e hospitalar, respectivamente. O grupo que falhou em relação ao grupo que obteve sucesso no desmame apresentou menor área transversa do reto femoral (1,4 [0,8] versus 1,84 [0,76]cm2, p = 0,014) e menor excursão diafragmática (1,29 ± 0,62 versus 1,62 ± 0,51cm, p = 0,019). Quando a área de secção transversa do reto femoral ≥ 1,80cm2 e a excursão diafragmática ≥ 1,25cm era uma condição combinada, apresentava forte associação com sucesso no desmame (RC ajustada de 20,81; IC95% 2,38 - 182,28; p = 0,006), mas não com sobrevida na unidade de terapia intensiva (RC ajustada de 0,19; IC95% 0,03 - 1,08; p = 0,061). Conclusão: O sucesso no desmame da ventilação mecânica em pacientes críticos crônicos foi associado a medidas maiores de área de secção transversa do reto femoral e da excursão diafragmática.

ABSTRACT Objective: To verify the relationship between the rectus femoris cross-sectional area and diaphragmatic excursion with successful weaning from mechanical ventilation in chronic critically tracheostomized patients. Methods: This was a prospective observational cohort study. We included chronic critically ill patients (those who underwent tracheostomy placement after 10 days under mechanical ventilation). The rectus femoris cross-sectional area and diaphragmatic excursion were obtained by ultrasonography performed within the first 48 hours after tracheostomy. We measured rectus femoris cross-sectional area and diaphragmatic excursion to assess their association with weaning from mechanical ventilation, including their potential to predict successful weaning and survival throughout the intensive care unit stay. Results: Eighty-one patients were included. Forty-five patients (55%) were weaned from mechanical ventilation. The mortality rates were 42% and 61.7% in the intensive care unit and hospital, respectively. The fail group in relation to the success group at weaning presented a lower rectus femoris cross-sectional area (1.4 [0.8] versus 1.84 [0.76]cm2, p = 0.014) and lower diaphragmatic excursion (1.29 ± 0.62 versus 1.62 ± 0.51cm, p = 0.019). When rectus femoris cross-sectional area ≥ 1.80cm2 and diaphragmatic excursion ≥ 1.25cm was a combined condition, it had a strong association with successful weaning (adjusted OR = 20.81, 95%CI 2.38 - 182.28; p = 0.006) but not with intensive care unit survival (adjusted OR = 0.19, 95%CI 0.03 - 1.08; p = 0.061). Conclusion: Successful weaning from mechanical ventilation in chronic critically ill patients was associated with higher measurements of rectus femoris cross-sectional area and diaphragmatic excursion.

Inter-rater reliability of the measurement of diaphragmatic excursion and fraction of diaphragmatic thickening by ultrasonography in healthy volunteers.

BACKGROUND AND OBJECTIVE: To determine the inter-rater reliability in the ultrasonographic (US) measurement of the diaphragmatic excursion (DE) and the diaphragm thickness fraction (DTF) performed by non-medical health professionals in healthy people. PARTICIPANTS AND METHODS: Prospective observational study in a third level hospital in Cali, Colombia. Measurements were made to 30 healthy volunteers chosen by convenience sampling, without a history of lung diseases, with ages between 18-60 years. A pilot test was previously carried out with 8 healthy volunteers. US measurements of DE, and DTF were based on previously published protocols. Each assessor independently observed several cycles of normal quiet breathing for 3min to establish a baseline. The Intraclass Correlation Index (ICC) was used to evaluate the inter-rater reliability in the measurements of DE and DTF, with 95% confidence intervals and a p<0.05. RESULTS: Substantial agreement was identified in the measurement of DE in the splenic and hepatic windows because the ICC was greater than 0.6 (p<0.05). The measurement of the DTF in the hepatic window showed slight agreement in both 2D and M modes (p>0.05). In the splenic window, the measurement of the DTF in the 2D mode was found to be moderate agreement and for the M mode a slight agreement was found (p>0.05). CONCLUSIONS: The diaphragmatic US constitutes a reproducible method with acceptable inter-rater reliability for the measurement of inspiratory/expiratory thickness, and with little reliability for the measurement of DTF.

Two devices to facilitate the perception of pelvic floor muscle contraction in the sitting position in women with urinary incontinence: comparative analysis / Dois dispositivos facilitadores de percepção da contração do assoalho pélvico na posição sentada em mulheres com incontinência urinária: análise comparativa / Dos herramientas que facilitan la percepción de la contracción del suelo pélvico en posición sentada de mujeres con incontinencia urinaria: un análisis comparativo

ABSTRACT The use of support devices may facilitate the perception of pelvic floor muscle (PFM) contraction, which is difficult to be performed. Therefore, this study aimed to compare the perception of PFM contraction in the sitting position during the use of two different support devices on women with PFM dysfunction. This is a cross-sectional study performed with 37 women with stress or mixed urinary incontinence (UI). All women performed three free PFM contractions sitting on a chair, followed by three contractions using each support device (sand pads and a cylindrical foam, which provide sciatic and perineal support, respectively). Women scored the perception of PFM contraction from 1 to 5, as well as the perception of facilitation of contraction (higher grades show better results) and discomfort (higher grades show more discomfort) when compared with free contraction. The cylindrical foam presented similar results to sand pads for the perception of PFM contraction (2.84±1.61 vs. 3.19±1.43; p=0.34) and facilitation of contraction (3.38±1.34 vs. 3.19±1.54; p=0.61), as well as for their discomfort (1.83±1.23 vs. 1.5±1.16; p=0.20). Of all women, 57% preferred sand pads. Thus, both sand pads (sciatic support) and the cylindrical foam (perineal support) improved the perception of PFM contraction and facilitation of contraction in the sitting position of women with PFM dysfunction when compared with sitting with no device. The two devices presented no difference between them.

RESUMO O uso de dispositivos de suporte pode auxiliar na percepção da contração dos músculos do assoalho pélvico (AP). O objetivo deste estudo foi, comparar na posição sentada, a percepção da contração dos músculos do AP durante o uso de dois tipos diferentes de dispositivos, em mulheres com disfunção dos músculos do AP. Para tanto, foi realizado um estudo transversal com 37 mulheres com incontinência urinária (IU) de esforço ou mista. Primeiro as participantes faziam três contrações livres dos músculos do AP sem o uso de dispositivos, sentadas em uma cadeira. Em seguida, faziam três contrações utilizando cada um dos dois dispositivos: almofadas de areia e uma espuma cilíndrica, que forneciam apoio isquiático e perineal, respectivamente. As pacientes atribuíram nota de 1 a 5 para a percepção que tiveram da contração dos músculos do AP, da facilitação da contração (quanto maior a nota, melhor o resultado) e do desconforto com o dispositivo (quanto maior a nota, maior o desconforto) em comparação às contrações livres. Como resultados principais, verificou-se que o uso da almofada cilíndrica foi similar ao das almofadas de areia para a percepção da contração dos músculos do AP (2,84±1,61 vs. 3,19±1,43; p=0,34), e da facilitação da contração (3,38±1,34 vs. 3,19±1,54; p=0,61), assim como do desconforto (1,83±1,23 vs. 1,5±1,16; p=0,20). Entre as participantes, 57% relataram preferir as almofadas de areia. Concluiu-se que em mulheres com incontinência urinária, tanto as almofadas de areia (apoio isquiático) quanto a espuma cilíndrica (apoio perineal) melhoraram a percepção da contração e facilitaram a contração dos músculos do assoalho pélvico na posição sentada, não havendo, no entanto, diferença entre os dispositivos.

RESUMEN Las herramientas de apoyo pueden ayudar en la percepción de la contracción de los músculos del suelo pélvico (SP), que no siempre es fácil de obtener su medición. El objetivo de este estudio fue comparar si dos tipos diferentes de herramientas ayudan a las mujeres con disfunción muscular del SP a contraer estos músculos en posición sentada. Para ello, se realizó un estudio transversal con 37 mujeres con incontinencia urinaria (IU) de esfuerzo o mixta. Primero, las participantes realizaron tres contracciones libres de los músculos del SP sentadas en una silla, sin el uso de herramientas de apoyo. Luego, realizaron tres contracciones utilizando cada uno de los dos dispositivos de apoyo: almohadillas de arena y espuma cilíndrica, que brindan apoyo isquiático y perineal, respectivamente. Las participantes deberían asignar una puntuación de 1 a 5 cuanto a su percepción de la contracción muscular del SP, de la facilitación de la contracción (cuanto mayor sea la puntuación, mejor será el resultado) y la incomodidad con la herramienta (cuanto mayor sea la puntuación, mayor será la incomodidad) en comparación con las contracciones libres. Los principales resultados encontrados apuntan que el uso de la almohadilla cilíndrica fue similar al de las almohadillas de arena en cuanto a su percepción de la contracción de los músculos del SP (2,84±1,61 vs. 3,19±1,43; p=0,34), y la facilitación de la contracción (3,38±1,34 vs. 3,19±1,54; p=0,61), así como la incomodidad (1,83±1,23 vs. 1,5±1,16; p=0,20). El 57% de las participantes informó preferir las almohadillas de arena. Se concluyó que tanto las almohadillas de arena (apoyo isquiático) como la espuma cilíndrica (apoyo perineal) mejoraron la percepción y la facilitación de la contracción muscular del SP en posición sentada de mujeres con disfunción muscular del SP en comparación con la ausencia de la herramienta, sin embargo, hay no hubo diferencia entre las herramientas.
