Influence of probe position in the measurement of muscle thickness and its association with lean mass: an ultrasound study / Influencia de la posición de la sonda en la medición del grosor muscular y su asociación con la masa magra: un estudio ecográfico

SUMMARY: Skeletal muscles play a fundamental role in people's lives and their evaluation provides significant information on health. Different tools have been used to evaluate muscle mass, and the evaluation of muscle thickness (MT) using ultrasound has been included as an alternative, which can be performed with the probe in different positions; however, these could present differences. The objectives of this study were to determine whether there are differences in the measurement of MT in the vastus lateralis (VL) muscle using the probe in the longitudinal or transverse position, and to determine its association with the lean mass of the lower limbs. The results indicated no significant differences between MT measurements with the probe in the longitudinal and transverse positions (p =0.084). However, when associating these measurements with lower limb lean mass, it was found that transverse measurements had a strong association (r =0.547; p < 0.001), while longitudinal measurements had a moderate association (r =0.351; p =0.007). This suggests that measurements with the probe positioned transversely to measure the MT would be the best option. Therefore, it could be useful as an indicator of lower limb lean mass in the absence of tools, such as bioelectrical bioimpedance or magnetic nuclear resonance.

El músculo esquelético cumple un rol fundamental en la vida de las personas, y su evaluación entrega mucha información de la salud. Se han utilizado diferentes herramientas para evaluar la masa muscular, y el último tiempo se ha incluido la evaluación del grosor muscular (MT) a través de la ecografía como una alternativa para estimarla, las cuales se pueden realizar con la sonda en distintas posiciones, sin embargo, estas podrían presentar diferencias. Los objetivos del estudio fueron determinar si existen diferencias en la medición de MT en el músculo vasto lateral (VL) utilizando la sonda en posición longitudinal o transversal y determinar su asociación con la masa magra de los miembros inferiores. Los resultados indican que no existen diferencias significativas entre las mediciones de MT con la sonda en posición longitudinal y transversal (valor p: 0.084). Sin embargo, al asociar estas mediciones con la masa magra de los miembros inferiores, se encontró que las mediciones transversales poseen una asociación fuerte (r: 0.547; valor p < 0.001), mientras que las mediciones longitudinales presentan una asociación moderada (r: 0.351; valor p: 0.007). Esto sugiere que las mediciones con la sonda posicionada transversal para medir MT serían la mejor opción. Por lo tanto, podría ser de utilidad como un indicador de masa magra de los miembros inferiores en caso de no contar con herramientas como la bioimpedancia bioeléctrica o resonancia nuclear magnética.

Premature newborn positionings and physiologic parameters - a randomized clinical study / Posicionamentos de recém-nascidos prematuros e parâmetros fisiológicos - um estudo clínico randomizado

Abstract Introduction Multiple studies have shown the effects of prone (PP), supine (SP) and kangaroo (KP) positions on clinical and physiological outcomes in preterm newborns, but none compared these three types of positioning between them. Objective To investigate the influence of these positionings on heart rate, respiratory rate, peripheral oxygen saturation (SpO2) and alertness status in clinically stable preterm newborns (NBs) admitted to a neonatal intensive care unit. Methods In a randomized clinical trial, clinically stable NBs with gestational ages from 30 to 37 weeks who were breathing spontaneously were allocated in three positioning groups: PP, SP and KP. Heart rate, breathing frequency, SpO2 and alertness status were evaluated immediately before and after 30 minutes of positioning. Results In all, 66 NBs were assessed (corrected age: 35.48 ± 1.94 weeks; weight: 1840.14 ± 361.09 g), (PP: n = 22; SP: n = 23; KP: n = 21). NBs in the PP group showed a significant improvement in peripheral SpO2 (97.18 ± 2.16 vs 95.47 ± 2.93 vs 95.57 ± 2.95, p = 0.03) compared with the SP and KP groups. Conclusion In clinically stable preterm NBs, the PP was associated with better peripheral oxygen saturation than the SP or KP. In addition, there was a reduction in heart rate within prone position group and in the KP group there was an increase in the number of NBs in the deep sleep classification.

Resumo Introdução Vários estudos têm demonstrado os efeitos das posições prona (PP), supina (SP) e canguru (KP) sobre os resul-tados clínicos e fisiológicos em recém-nascidos prematuros, mas nenhum comparou esses três tipos de posicionamento. Objetivo Investigar a influência desses posicionamentos na frequência cardíaca, frequência respiratória, saturação periférica de oxigênio (SpO2) e estado de alerta em recém-nascidos pré-termo (RN) clinicamente estáveis internados em uma unidade de terapia intensiva neonatal. Métodos Em um ensaio clínico randomizado, RN clinicamente estáveis com idade gestacional de 30 a 37 semanas e respirando espontaneamente foram alocados em três grupos de posicionamento: PP, SP e KP. Frequência cardíaca e respiratória, SpO2 e estado de alerta foram avaliados imediatamente antes e após 30 minutos de posicionamento. Resultados Ao todo, foram avaliados 66 RNs (idade corrigida: 35,48 ± 1,94 semanas; peso: 1840,14 ± 361,09 g), (PP: n = 22; SP: n = 23; KP: n = 21). Os RNs do grupo PP apresentaram melhora significativa na SpO2 periférica (97,18 ± 2,16 vs 95,47 ± 2,93 vs 95,57 ± 2,95, p = 0,03) em comparação aos grupos SP e KP. Conclusão Em RN prematuros clinicamente estáveis, o PP foi associado à melhor saturação periférica de oxigênio do que o SP ou KP. Além disso, houve redução da frequência cardíaca no grupo de posição prona e no grupo KP houve aumento do número de RNs na classificação sono profundo.

Fluid preloading before beach chair positioning for arthroscopic shoulder procedures: a randomized controlled trial

Abstract Background and objectives The Beach Chair Position (BCP) has many advantages such as less neurovascular injury and better intra-articular visualization, but it has also negative consequences, including hemodynamic instability. Although maintaining normal Mean Arterial Pressure (MAP) is important, fluid management is also a crucial concept for hemodynamic stability. The main objective of this study is whether preloading before positioning would be effective for less hemodynamic instability. Methods This randomized, controlled study was conducted in a single center in the Istanbul University, Istanbul Faculty of Medicine. Forty-nine patients undergoing elective arthroscopic surgery in the BCP were recruited. In the study group, crystalloid fluid at 10 mL.kg-1 of ideal body weight was administered intravenously 30 min before the BCP for preloading. The primary outcome measures were differences of hemodynamic variables as MAP, Stroke Volume (SV), Heart Rate (HR), and Cardiac Output (CO). The secondary outcome measures were Postoperative Nausea and Vomiting (PONV) rates in postoperative first day, surgical satisfaction scale, total ephedrine dose used during surgery, and total amount of fluid. Results The MAP, CO, and SV measurements of the study group were higher than those of the control group in the 5th minute after the BCP (respectively, p= 0.001, p= 0.016, p= 0.01). The total amount of crystalloid and surgical satisfaction scales were higher in the study group (respectively, p= 0.016, p= 0.001). Total amount of colloid and ephedrine dose used in the intraoperative period, and PONV rates were lower in the study group (p= 0.003, p= 0.018, p= 0.019, respectively). Conclusion Consequently, preloading can be favorable approach to preserve hemodynamic stability.

Con el reposicionamiento de partículas se busca eliminar el vértigo y sus síntomas asociados como lo son el mareo residual y la inestabilidad. Objetivo: Determinar si la maniobra de reposicionamiento de Epley (MRE) produce una modificación significativa del control postural (CP) en aquellos pacientes con VPPB de canal semicircular posterior (VPPB-CSC-P). Material y Método: Se realizó un estudio descriptivo prospectivo en una muestra de 21 pacientes con diagnóstico de VPPB-CSC-P. Comparamos el desplazamiento, la velocidad y el área del centro de presión (CoP) antes y después de la MRE. Resultados: La velocidad y el área de la CoP estudiada por posturografía computarizada muestra una disminución significativa en sus valores después de la MRE, mientras que el desplazamiento de la CoP se mantuvo sin cambios. Conclusión: La MRE ejecutada en pacientes con VPPB-CSC-P produce una modulación en el control de la CoP, demostrada por la disminución de la velocidad y el área de desplazamiento de la CoP. El éxito de la MRE produce modulación del CP.

Abstract Introduction: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral condition in otoneurologic diseases. With the repositioning of particles, the aim is to eliminate vertigo and its associated symptoms, such as residual dizziness and instability. Aim: To determine if the Epley repositioning maneuver (ERM) produces a significant modification of postural control (PC) in those patients with posterior semicircular canal BPPV (BPPV-CSC-P). Material and Method: A prospective descriptive study was carried out in a sample of 21 patients diagnosed with BPPV-CSC-P. We compared the displacement, velocity, and area of the center of pressure (CoP) before and after the Epley repositioning maneuver. Results: The velocity and the area of the CoP studied by computed posturography show a significant decrease in its values after the MRE, while the CoP shift remained unchanged. Conclusion: ERM performed in patients with BPPV-CSC-P produces an improvement in the control of the CoP, demonstrated by the decrease in the speed and the area of movement of the CoP. The success of the MRE produces modulation of the PC.

The following stood out as per the scale applied: use of conventional mattress + cotton field cushions as a support surface (100%); supine position (78%); upper limbs with opening less than 90º (70.5%); regional anesthesia (54.1%), and surgical time of 1h-2h (46.6%). A mean score of 17.6±3.29 points was found and 75.3% of the sample presented low risk for the development of injuries related to surgical positioning. Conclusion: around 25% of the sample presented a higher risk of injuries arising from surgical positioning.

Renal replacement therapy by the popliteal vein in a critical patient with COVID-19 in the prone position / Terapia renal substitutiva pela veia poplítea em paciente crítico com COVID-19 na posição de pronação

Abstract This patient was a 73-year-old man who initially came to our service with acute respiratory failure secondary to COVID-19. Soon after hospitalization, he was submitted to orotracheal intubation and placed in the prone position to improve hypoxia, due to severe acute respiratory syndrome (SARS). On the third day of hospitalization, he developed acute oliguric kidney injury and volume overload. The nephrology service was activated to obtain deep venous access for renal replacement therapy (RRT). The patient could not be placed in the supine position due to significant hypoxemia. A 50-cm Permcath (MAHURKARTM, Covidien, Massachusetts, USA) was inserted through the left popliteal vein. This case report describes a possible challenging scenario that the interventional nephrologist may encounter when dealing with patients with COVID-19 with respiratory impairment in the prone position.

Resumo O paciente era um homem de 73 anos de idade que inicialmente veio ao nosso serviço com insuficiência respiratória aguda secundária à COVID-19. Logo após a internação, ele foi submetido à intubação orotraqueal e pronado para melhorar a hipóxia devido à síndrome respiratória aguda grave (SARS - do inglês "severe acute respiratory syndrome"). No terceiro dia de internação, o mesmo desenvolveu lesão renal aguda oligúrica e sobrecarga de volume. O serviço de nefrologia foi acionado para realizar acesso venoso profundo para terapia renal substitutiva (TRS). O paciente não pôde ser colocado na posição de decúbito dorsal devido a uma hipoxemia significativa. Um Permcath de 50 cm (MAHURKARTM, Covidien, Massachusetts, EUA) foi inserido através da veia poplítea esquerda. Este relato de caso descreve um possível cenário desafiador com o qual o nefrologista intervencionista pode se deparar ao lidar com pacientes com COVID-19 com problemas respiratórios e colocados em pronação.

Importance of radiography in orthostatism in the conduct of thoracolombar transition fractures / Importância da radiografia em ortostatismo na conduta de fraturas da transição toracolombar / Importancia de la radiografía en ortostatismo en la conducta de fracturas de la transición toracolumbar

ABSTRACT Objective: To evaluate the importance of radiography in the orthostatic position in the initial assessment of patients with thoracolumbar transition fractures and whether this image changes the surgical indication. Methods: Medical records and imaging tests of patients treated for thoracolumbar transition fractures from June 2018 to June 2019 were evaluated. Trauma patients between 18 and 60 years of age with fractures of T10 to L3 who had been indicated for conservative treatment were included. Cases of fractures considered unstable were excluded. Radiographs were taken with the patient in the supine position (supine X-ray), computed tomography (CT), and orthostatic radiography (orthostatic X-ray). Segmental kyphosis and degree of wedging were evaluated. The measurements were compared using the Wilcoxon test. The McNemar test was used to assess changes in conduct according to the criteria for surgical indication (kyphosis ≥ 25 ° and wedging ≥ 50%). Results: Fifty patients were evaluated, nine of whom (18%) were indicated for a change of conduct according to the orthostatic examinations and were submitted to surgical treatment. Vertebral kyphosis increased by 40.6% (p <0.001). The wedging increased by 25.62% (p <0.0001). Conclusion: Eighteen percent of the total number of patients who did not present instability criteria in radiographs in the supine position satisfied at least one of these criteria when the orthostatic X-ray was performed. Level of evidence 3B; Retrospective case series study.

RESUMO Objetivo: Avaliar a importância da radiografia em posição ortostática na avaliação inicial dos pacientes com fraturas da transição toracolombar e se essa imagem modifica a indicação cirúrgica. Métodos: Foram avaliados prontuários e exames de imagens dos pacientes atendidos com fraturas da transição toracolombar, no período de junho 2018 a junho 2019. Foram incluídos pacientes vítimas de trauma, entre 18 e 60 anos de idade, com fraturas de T10 a L3, que tinham indicação de tratamento conservador. Foram excluídos os casos de fraturas consideradas instáveis já na avaliação inicial. Foram realizadas radiografias com o paciente na posição supina (Rx supino), tomografia computadorizada (TC) e radiografia ortostática (Rx ortostático). Foram avaliados a cifose segmentar e o grau de cunha. As medidas foram comparadas com o teste de Wilcoxon. Foi usado o teste de McNemar para avaliar mudanças de conduta de acordo com os critérios de indicação cirúrgica (cifose ≥ 25° e cunha ≥ 50%). Resultados: Foram avaliados 50 pacientes, sendo que nove (18%) tiveram indicação de mudança de conduta de acordo com os exames ortostáticos e foram submetidos a tratamento cirúrgico. A cifose vertebral aumentou 40,6 % (p < 0,001). O grau da cunha aumentou 25,62% (p < 0,0001). Conclusões: Do total, 18% dos pacientes que não apresentavam critérios de instabilidade nas radiografias em posição supina apresentaram pelo menos um desses critérios quando se realizou o Rx ortostático. Nível de evidência 3B; Estudo série de casos retrospectivos.

The necessity of post-maneuver postural restriction in treating posterior canal benign paroxysmal positional vertigo: a Meta-analytic study / 中华耳鼻咽喉头颈外科杂志

Objective: We conducted a Meta-analysis to investigate the necessity of postural restrictions after manual reduction in the treatment of posterior canal benign paroxysmal positional vertigo (PC-BPPV). Methods: We searched PubMed, EBSCO, Proquest, Web of Science databases, Ovid, and screened eligible studies that investigated the effect of post-maneuver postural restriction in treating patients with PC-BPPV. Outcomes included the efficacy of treatment and recurrence. Meta-analysis was performed using Stata 15.0 software. Results: Studies of the single visit efficiency included 11 references, with a sample size of 1 733 cases. The Meta-analysis results showed that the difference in the efficacy between the postural restricted group and the non-postural restricted group in PC-BPPV patients was statistically significant(RR=1.12, 95%CI=1.07-1.18, P<0.001). There were 12 references included in the study on the total efficiency, with a cumulative sample size of 1763 cases. There was no statistically significant difference between the effect of postural restriction after manipulative reduction and that of simple manipulative reduction (RR=1.03, 95%CI=0.99-1.08, P=0.118). There were 5 references included in the study of recurrence rate, and the cumulative sample size was 659 cases. There was no statistically significant difference in the recurrence rate between the postural restricted group and the non-postural restricted group(RR=0.98, 95%CI=0.62-1.54, P=0.937). Conclusions: In comparison with non-postural restriction group, post-maneuver postural restriction after a single visit can improve the treatment effective rate of PC-BPPV and contribute to the improvement in the symptoms of patients in a short term. However, postural restrictions has no significant effect on the final prognosis of PC-BPPV, and it also has no significant effect on the recurrence.

Intervention strategies for residual dizziness after successful repositioning maneuvers in benign paroxysmal positional vertigo: a single center randomized controlled trial / 中华耳鼻咽喉头颈外科杂志

Objective: To compare the effects of different intervention strategies for the management of residual dizziness following successful canalith repositioning procedure (CRP) in patients with benign paroxysmal positional vertigo (BPPV). Methods: A total of 129 BPPV patients with residual dizziness following successful CRP were recruited during January 2019 and July 2019. They were randomly assigned into three groups with 43 cases in each group: the vestibular rehabilitation group received rehabilitation training for four weeks; betahistine group was given orally 12 mg betahistine three times a day for four weeks; and the control group had no specific treatment. The primary outcomes were daily activities and social participation assessed by the Vestibular Activities and Participation measure (VAP). Secondary outcomes includedbalance function assessed by sensory organization test (SOT) and the duration of residual symptoms. Stata15.0 software was used for statistical analysis. Results: The scores of VAP in the three groups decreased over time, but a more significant decrease was found in vestibular rehabilitation group. Further paired comparison showed that the difference between the vestibular rehabilitation group and the control group was of statistical significance (B=-3.88, χ2=18.29, P<0.01), while the difference between the betahistine group and the control group was not statistically significant (B=-0.96, χ2=1.16, P=0.28). The balance function of the three groups showed a trend of recovery over time, with no significant differences between groups (χ2=1.37, df=2, P>0.05). The median duration of residual dizziness for both vestibular rehabilitation and betahistine groups was 14 days, while that of control group was 19 days, with no significant difference between three groups[Log-rank (Mantel-Cox) test; χ2=1.82, df=2, P=0.40]. Conclusion: Vestibular rehabilitation can significantly improve the daily activities and social participation function in BPPV patients with residual symptoms following successful CRP, but its effects on shortening the duration of residual symptoms and promoting the recovery of balance function remain uncertain.

Effects of hammock positioning on clinical parameters in preterm infants admitted to a neonatal intensive care unit: a systematic review / Efeitos da rede de posicionamento nos parâmetros clínicos de prematuros admitidos em unidade de terapia intensiva neonatal: uma revisão sistemática

ABSTRACT Objective: To review the effects of the hammock positioning on clinical parameters of preterm newborn infants (PTNB) admitted to the Neonatal Intensive Care Unit (NICU). Data sources: This was a systematic review performed by searching the Pubmed, Lilacs, SciELO and PEDro databases. Intervention studies in English, Portuguese and Spanish that evaluated the effects of hammock positioning on clinical parameters of PTNB admitted to the NICU were selected. Three search strategies were used: 1) hammock positioning OR patient positioning AND intensive care units AND infant, newborn; 2) hammock positioning OR patient positioning AND intensive care units; 3) hammock positioning OR patient positioning AND intensive care units, neonatal. There was no restriction on the year of publication of the articles. Methodological quality was assessed by the PEDro scale. Data synthesis: Among 597 articles, only six were included and 139 neonates with gestational ages between 26 and 37 weeks and an average gestational weight <2240g were analyzed. Four studies included patients without any associated pathology and most of them placed the PTNB supine in hammock positioning. The duration of the intervention ranged from 15 to 180 minutes and most applied it at just one moment. There was an improvement in heart rate (HR), respiratory rate (RR) and pain (3/4 studies), as well as gains in peripheral oxygen saturation (SpO2) (2/4 studies). Only one study reported worsening of SpO2 with the intervention. The methodological quality of the studies was classified as low. Conclusions: Although this review suggests improvement with hammock positioning in HR, RR and pain in PTNB, the low methodological quality makes the results inconsistent.

RESUMO Objetivo: Revisar os efeitos da rede de posicionamento nos parâmetros clínicos de recém-nascidos pré-termo (RNPT) admitidos em Unidade de Terapia Intensiva Neonatal (UTIN). Fontes de dados: Trata-se de uma revisão sistemática realizada na PubMed, na Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs), na Biblioteca Eletrônica Científica Online (SciELO) e na Base de Dados em Evidências em Fisioterapia (PEDro). Selecionaram-se estudos de intervenção, nos idiomas inglês, português e espanhol, que avaliaram os efeitos da rede de posicionamento sobre parâmetros clínicos de RNPT admitidos em UTIN. Foram utilizadas três estratégias de busca: hammock positioning OR patient positioning AND intensive care units AND infant, newborn; hammock positioning OR patient positioning AND intensive care units; e hammock positioning OR patient positioning AND intensive care units, neonatal. Não houve restrição quanto ao ano de publicação dos artigos. A qualidade metodológica foi avaliada pela escala PEDro. Síntese dos dados: De um total de 597 artigos, apenas seis foram incluídos. As amostras totalizaram 139 neonatos, com idade gestacional entre 26 e 37 semanas e média de peso gestacional <2.240 g. Quatro estudos incluíram pacientes sem nenhuma patologia associada, e a maior parte deles dispôs os RNPT em supino na rede de posicionamento. A duração da intervenção variou de 15 até 180 minutos, e a maioria aplicou essa intervenção em apenas um momento. Foi observada melhora na frequência cardíaca (FC), na frequência respiratória (FR) e na dor (3/4 estudos), além de ganhos na saturação periférica de oxigênio (SpO2) (2/4 estudos). Apenas um artigo relatou piora da SpO2 com a intervenção. A qualidade metodológica foi classificada como baixa. Conclusões: Embora a rede de posicionamento pareça causar melhora na FC, na FR e na dor em RNPT, a baixa qualidade metodológica torna inconsistentes os resultados.
