Uso de dispositivos móviles y alteraciones cervicales en estudiantes universitarios / Use of mobile devices and cervical disorders in university students / Uso de dispositivos móveis e distúrbios cervicais em estudantes universitários

Las alteraciones cervicales son un problema multifactorial que afecta a la sociedad moderna. Posturas viciosas, traumatismos y defectos congénitos relacionados con la columna cervical pueden desarrollar inestabilidad, pinzamiento radicular, cervicoartrosis y cervicalgias. Objetivo. Relacionar el uso de dispositivos móviles con las alteraciones cervicales en estudiantes universitarios. Materiales y métodos. Estudio descriptivo, observacional, que se realizó entre los meses de mayo y julio del 2023, cuya muestra fue de 172 estudiantes universitarios que se obtuvo aplicando la fórmula para el cálculo muestral de poblaciones conocidas, mediante un muestreo no probabilístico. Se utilizó el test goniométrico para medir el rango articular, el test postural para identificar las alteraciones posturales, la técnica de palpación para identificar dolor inespecífico, prueba de resistencia para los músculos flexores (NFMET) y extensores (NEET), por último, se realizó la prueba de Spurling para identificar casos de radiculopatías. Resultados. Aunque las relaciones estadísticas no fueron consistentes, se observó que quienes utilizaron más tiempo los teléfonos celulares (87,0%) mostraron más limitaciones cervicales que los usuarios menos frecuentes (73,5%). La movilidad articular fue limitada en el 84,3% de la población, especialmente en varones (93,5%); la resistencia muscular normal en extensión fue más prevalente en el caso de los hombres (84,9%), mientras que la resistencia alterada en flexión fue más prevalente en mujeres (94,9%). Conclusiones. Según los resultados obtenidos en esta investigación, no se encontró suficiente evidencia para determinar una relación estadísticamente significativa (P˃0,05) entre las alteraciones cervicales y el uso de teléfonos celulares, aunque se observó una mayor limitación en el caso de quienes más tiempo utilizaban el dispositivo móvil.

Cervical disorders are a multifactorial problem affecting modern society. Vicious postures, trauma and congenital defects related to the cervical spine can develop instability, radicular impingement, cervicoarthrosis and cervicalgia. Objective. To relate the use of mobile devices with cervical disorders in university students. Materials and methods. Descriptive, observational study carried out between May and July 2023, with a sample of 172 university students obtained by applying the formula for the sample calculation of known populations, by means of non-probabilistic sampling. The goniometric test was used to measure joint range, the postural test to identify postural alterations, the palpation technique to identify non-specific pain, resistance test for flexor (NFMET) and extensor (NEET) muscles, and finally, the Spurling test was performed to identify cases of radiculopathy. Results. Although the statistical relationships were not consistent, it was observed that those who used cell phones longer (87.0%) showed more cervical limitations than less frequent users (73.5%). Joint mobility was limited in 84.3% of the population, especially in men (93.5%); normal muscular endurance in extension was more prevalent in men (84.9%), while impaired endurance in flexion was more prevalent in women (94.9%). Conclusions. According to the results obtained in this investigation, there was not enough evidence to determine a statistically significant relationship (P˃0.05) between cervical alterations and cell phone use, although a greater limitation was observed in the case of those who used the mobile device the longest.

Degeneración combinada subaguda

Introducción: La degeneración combinada subaguda (DCS) es un trastorno caracterizado por la degeneración difusa de la sustancia blanca a nivel del SNC, que afecta específicamente los cordones posteriores y laterales de la médula espinal, con pérdida de la mielinización periférica y central. De manera frecuente, las manifestaciones clínicas son parestesias y debilidad generalizada causada por deficiencia de vitamina B12. Presentación del caso: Paciente masculino de 79 años, con cuadro clínico de 3 meses de evolución de limitación funcional para la marcha acompañado de desorientación. Al examen físico evidenció desorientación, cuadriparesia e hiporreflexia, con niveles séricos bajos de vitamina B12, RM cervical con focos hiperintensos en el segmento C3/C6 y endoscopia de vías digestivas altas con atrofia de la mucosa gástrica. Presentamos un caso clínico de DCS. Discusión: Este es un caso de DCS que se manifiesta por medio de una alteración neuropsiquiátrica, con una presentación inicial inespecífica que comprende deterioro de la marcha, movimientos anormales con afectación cognitiva y psiquiátrica dada por alucinaciones visuales y desorientación. Su sospecha es importante en pacientes con factores de riesgo por medio del conocimiento de la patología, para una adecuada sospecha diagnóstica y una instauración oportuna de reposición vitamínica, la cual presenta una excelente respuesta. Conclusión: La DCS es un trastorno en el que se evidencia anemia con deficiencia de vitamina B12, des-mielinización del tejido nervioso y en muchos casos signos sugestivos de atrofia gástrica, y para ello es crucial la detección temprana de esta enfermedad por medio de la determinación de niveles séricos de vitamina B12, asociado a síntomas neurológicos, para así lograr su adecuado diagnóstico y tratamiento.

Introduction: Subacute combined degeneration (DCS) is a disorder characterized by diffuse degeneration of white matter at the CNS level, specifically affecting the posterior and lateral cords of the spinal cord, also with loss of peripheral and central myelination, frequently the clinical manifestations are paresthesias and generalized weakness caused by vitamin B12 deficiency. Case presentation: A 79-year-old male patient with a 3-month history of functional limitation for walking accompanied by disorientation. On physical examination, he revealed disorientation, quadriparesis, and hyporeflexia, with low serum levels of vitamin B12, cervical MRI with hyperintense foci in segment C3/C6, and upper digestive tract endoscopy with atrophy of the gastric mucosa. We present a clinical case of DCS. Discussion: This is a case of DCS that manifests itself through neuropsychiatric alteration with a nonspecific initial presentation with gait impairment, abnormal movements with cognitive and psychiatric affectation given by visual hallucinations and disorientation. Its suspicion is important in patients with risk factors. risk through knowledge of the pathology for an adequate diagnostic suspicion and a timely establishment of vitamin replacement for which it presents an excellent response. Conclusion: DCS is a disorder where anemia with vitamin B12 deficiency, demyelination of the nervous tissue and in many cases signs suggestive of gastric atrophy are evident, for which early detection of this disease is crucial through the determination of serum levels of vitamin B12 associated with neurological symptoms, in order to achieve its proper diagnosis and treatment.

Influence of handgrip strength on pharyngeal transit time in individuals with chronic obstructive pulmonary disease

Abstract Objective: To investigate the relationship between Handgrip Strength (HGS), dysphagia classification, nutritional aspects, and Pharyngeal Transit Time (PTT) in subjects with Chronic Obstructive Pulmonary Disease (COPD). Methods: Study based on the analysis of secondary data from a database. The sample comprised 15 COPD patients of both sexes and a mean age of 65.7 years. We collected information on HGS, videofluoroscopic swallowing study, Volume-Viscosity Swallow Test (V-VST), and Body Mass Index (BMI). We applied correlation, effect size, and logistic regression tests at the 5% significance level. Results: Most individuals had severe COPD (66.7%), mean dominant HGS of 28.2, and non-dominant HGS of 25.3. Five subjects were malnourished, five were well-nourished, and five were obese. Most of them had normal swallowing (40%), normal V-VST results (60%), and PTT of 0.89 s (liquid) and 0.81 s (pudding-thick). There was no significant correlation between the swallowing classification and the other variables. We obtained a significant correlation (p = 0.015), though weak (r = -0.611), between non-dominant HGS and PTT. Regarding the binary logistic regression, HGS variables and HGS asymmetry were not enough to be considered a risk to clinically abnormal swallowing (V-VST). Conclusion: Subjects with COPD in this study had a longer PTT than reported in the literature for normal subjects and a weak correlation between PTT and non-dominant HGS. The variables related to muscle condition were not considered predictors for abnormal swallowing. Level of evidence: 3.

Analyzing respiratory muscle weakness and thoracopulmonary restriction in subjects with duchenne muscular dystrophy / Análisis de la debilidad de los músculos respiratorios y de la restricción toracopulmonar en sujetos con distrofia muscular de Duchenne

Abstract Objective: To analyze the underlying components of reduced maximal static inspiratory (MIP) and expiratory (MEP) pressures in subjects with Duchenne muscular dystrophy. Methods: Forty-three subjects were assessed based on routine pulmonary function tests. MIP and MEP were measured the subjects performed maximal expirations and inspirations using a snorkel mouthpiece. Lung volumes were measured us ing the helium dilution technique. Results: The mean age was 13 years (range, 7-20 years). Median total lung capacity (TLC) and residual volume (RV) were 78.0 (49.0-94.0) and 27.0 (19.7-30.1) of the predicted values re spectively. The RV/TLC relationship was 35.3% (28.1-47.7). Thirty-five subjects had a TLC below the lower limit of normal, while 31 had an RV/TLC ratio above the upper limit of normal. The median (IQR) MIP and MEP values were -53.0 (-65.5 to -41.8) and 58.0 (41.5-74.8) cmH2O respectively. MIP and MEP in percent of the predicted values (predicted TLC and RV) were 42.6 (33.3-50.8) and 33.7 (23.9-44.5). MIP in percent of the RV reached for Group A (7-11 years old) was higher (p 0.025) while MEP in percent of the TLC reached for Group B (12-16 years) and C (17-20 years) were higher too (0.031). Conclusions: In subjects with Duchenne muscular dystrophy, the intrinsic weakness of respiratory muscles and mechanical disadvantage lead to inadequate maximal static pressure generation. Maximal static pressures should be interpreted cautiously as they overestimate respiratory muscle weakness when compared to predicted values obtained at TLC and RV. Our results provide additional data supporting absolute values use rather than predicted values.

Resumen Objetivo: Analizar los componentes subyacentes de las presiones inspiratorias (MIP) y espiratorias (MEP) es táticas máximas reducidas en sujetos con distrofia de Duchenne (DMD). Métodos: Se evaluaron 43 pacientes mediante pruebas de función pulmonar rutinarias. MIP y MEP fueron medidas a inspiración y espiración máximas. Los volúmenes pulmonares se midieron mediante dilución de helio. Resultados: Edad media 13 años (rango 7-20 años). La capacidad pulmonar total (TLC) y el volumen residual (RV) fueron 78.0% (49.0-94.0) y 27.0% (19.7- 30.1) de los valores predichos. El RV/TLC fue de 35.3% (28.1-47.7). Treinta y cinco sujetos tenían una TLC por debajo del límite inferior de normalidad, 31 tenían una RV/TLC por encima del límite superior de la normalidad. MIP y MEP fueron -53.0 (-65.5 a -41.8) y 58.0 (41.5-74.8) cmH2O, mientras que en % de los predichos (TLC y RV predichos) fueron 42.6 (33.3-50.8) y 33.7 (23.9-44.5). MIP en % del RV alcanzado (Grupo A 7-11 años) fue mayor (p 0.025), y MEP en % de la TLC alcanzada Grupo B (12-16 años) y C (17-20 años), también fue mayor (0.031). Conclusiones: En sujetos con DMD, debilidad intrínseca de los músculos respiratorios y desventaja mecánica conducen a generación de presión estática máxima inadecuada. Las mismas deben interpretarse con cautela, ya que sobrestiman la debilidad de los músculos respiratorios si se las compara con las tablas de valores predichos obtenidos a TLC y RV. Nuestros resultados proporcionan datos adicionales que respaldan la utilización de valores absolutos en lugar de los predichos.

Enhanced endoplasmic reticulum RyR1 receptor phosphorylation leads to diaphragmatic dysfunction in septic rats / 南方医科大学学报

OBJECTIVE@#To explore the role of endoplasmic reticulum ryanodine receptor 1 (RyR1) expression and phosphorylation in sepsis- induced diaphragm dysfunction.@*METHODS@#Thirty SPF male SD rats were randomized equally into 5 groups, including a sham-operated group, 3 sepsis model groups observed at 6, 12, or 24 h following cecal ligation and perforation (CLP; CLP-6h, CLP-12h, and CLP-24h groups, respectively), and a CLP-24h group with a single intraperitoneal injection of KN- 93 immediately after the operation (CLP-24h+KN-93 group). At the indicated time points, diaphragm samples were collected for measurement of compound muscle action potential (CMAP), fatigue index of the isolated diaphragm and fitted frequencycontraction curves. The protein expression levels of CaMK Ⅱ, RyR1 and P-RyR1 in the diaphragm were detected using Western blotting.@*RESULTS@#In the rat models of sepsis, the amplitude of diaphragm CMAP decreased and its duration increased with time following CLP, and the changes were the most obvious at 24 h and significantly attenuated by KN-93 treatment (P < 0.05). The diaphragm fatigue index increased progressively following CLP (P < 0.05) irrespective of KN- 93 treatment (P>0.05). The frequency-contraction curve of the diaphragm muscle decreased progressively following CLP, and was significantly lower in CLP-24 h group than in CLP-24 h+KN-93 group (P < 0.05). Compared with that in the sham-operated group, RyR1 expression level in the diaphragm was significantly lowered at 24 h (P < 0.05) but not at 6 or 12 following CLP, irrespective of KN-93 treatment; The expression level of P-RyR1 increased gradually with time after CLP, and was significantly lowered by KN-93 treatment at 24 h following CLP (P < 0.05). The expression level of CaMKⅡ increased significantly at 24 h following CLP, and was obviously lowered by KN-93 treatment (P < 0.05).@*CONCLUSION@#Sepsis causes diaphragmatic dysfunction by enhancing CaMK Ⅱ expression and RyR1 receptor phosphorylation in the endoplasmic reticulum of the diaphragm.

Assessment of motor function in individuals with hemiplegia post-stroke / Evaluación de la función motriz en hemipléjicos posaccidente cerebrovascular / Avaliação da função motora em hemiplégicos pós-acidente vascular encefálico

ABSTRACT This study aims to compare the performance of the sit-to-stand test and walking speed in individuals with chronic hemiplegia post-stroke and a control group (CG). Moreover, we will investigate whether lower limb resistance, measured based on the sit-to-stand test, is related to walking speed in individuals with chronic hemiplegia and a CG. Finally, we will verify if there are intra-group differences for the tests by dividing the hemiplegia group (HG) according to motor and sensorimotor function assessment classification. A cross-sectional design was used among a group with chronic hemiplegia (n=28) and a healthy CG (n=22). The HG was classified by the Fugl-Meyer scale, and both groups were evaluated using the 1-minute sit-to-stand test. The walking speed was calculated using a 3D kinematics system. Lower limb resistance among HG differed significantly from the CG, as well as walking speed. We found a strong correlation between the tests (ρ=0.773; p<0.001). No differences were found for the sit-to-stand tests and walking speed when dividing the HG into individuals with greater or lesser motor and sensory impairment, using the Fugl-Meyer scale. Therefore, individuals with hemiplegia, regardless of having a more pronounced classification of motor and sensory impairment on the Fugl-Meyer scale, showed lower limb resistance and lower walking speed compared with individuals without hemiplegia post-stroke.

RESUMEN El objetivo de este estudio es comparar el desempeño del test de levantarse y sentarse y la velocidad de marcha en individuos con hemiplejía crónica debido a accidente cerebrovascular (ACV) y un grupo control (GC). Además, se investigará si existe asociación entre la resistencia de los miembros inferiores, medida desde el test de levantarse y sentarse, y la velocidad de marcha en individuos con hemiplejía crónica y un GC. Por último, se verificará si existen diferencias intragrupales en las pruebas al dividir el grupo hemiplejía (GH) según la clasificación de evaluación de deterioro motor y sensorial. El método utilizado fue el transversal en un grupo con hemiplejía crónica (n=28) y un GC sin ninguna patología (n=22). El GH se clasificó mediante la escala de Fugl-Meyer, y ambos grupos se evaluaron mediante el test de levantarse y sentarse de un minuto. La velocidad de marcha se calculó mediante el sistema cinemático tridimensional. Entre los resultados obtenidos, se observó que la resistencia de los miembros inferiores entre GH difería significativamente del GC, así como la velocidad de marcha. Se demostró una fuerte correlación entre las pruebas (ρ=0,773; p<0,001). No se encontraron diferencias en las pruebas de levantarse y sentarse y la velocidad de la marcha al dividir el GH en individuos con mayor o menor deterioro motor y sensorial, utilizando la escala de Fugl-Meyer. Por lo tanto, las personas con hemiplejía, independientemente de tener un mayor deterioro motor y sensorial según la escala de Fugl-Meyer, tuvieron una menor resistencia de las extremidades inferiores y una menor velocidad de marcha en comparación con las personas sin hemiplejía pos-ACV.

RESUMO O objetivo deste estudo é comparar os desempenhos no teste de sentar e levantar e a velocidade de caminhada de indivíduos com hemiplegia crônica decorrente de acidente vascular encefálico (AVE) e um grupo-controle (GC). Além disso, será investigado se existe associação entre a resistência de membros inferiores, mensurada a partir do teste de sentar e levantar, e a velocidade de caminhada em indivíduos com hemiplegia crônica e um GC. Por fim, será verificado se existem diferenças intragrupo para os testes ao dividir o grupo hemiplegia (GH) de acordo com a classificação de avaliação do comprometimento motor e sensorial. O método utilizado foi o delineamento transversal entre um grupo com hemiplegia crônica (n=28) e um GC sem nenhuma patologia (n=22). O GH foi classificado a partir da escala de Fugl-Meyer, e ambos os grupos foram avaliados por meio do teste de sentar e levantar de um minuto. A velocidade de caminhada foi calculada a partir de um sistema de cinemetria tridimensional. Entre os resultados obtidos, foi percebido que a resistência de membros inferiores do GH diferiu significativamente do GC, assim como a velocidade de caminhada. Foi demonstrada uma correlação forte entre os testes (ρ=0,773; p<0,001). Não foram encontradas diferenças nos testes de sentar e levantar e velocidade de caminhada ao dividir o GH em indivíduos com maior ou menor comprometimento motor e sensorial, com a escala de Fugl-Meyer. Portanto, indivíduos com hemiplegia, independentemente de ter uma classificação de comprometimento motor e sensorial mais acentuada na escala de Fugl-Meyer, apresentaram menor resistência de membros inferiores e menor velocidade de caminhada comparados com indivíduos sem hemiplegia pós-AVE.

Effects of mechanical in-exsufflation in preventing postextubation acute respiratory failure in intensive care acquired weakness patients: a randomized controlled trial / Efeitos da insuflação-exsuflação mecânica na prevenção da insuficiência respiratória aguda pós-extubação em pacientes com fraqueza adquirida em terapia intensiva: um estudo controlado e randomizado

ABSTRACT Objective: We hypothesized that the use of mechanical insufflation-exsufflation can reduce the incidence of acute respiratory failure within the 48-hour post-extubation period in intensive care unit-acquired weakness patients. Methods: This was a prospective randomized controlled open-label trial. Patients diagnosed with intensive care unit-acquired weakness were consecutively enrolled based on a Medical Research Council score ≤ 48/60. The patients randomly received two daily sessions; in the control group, conventional chest physiotherapy was performed, while in the intervention group, chest physiotherapy was associated with mechanical insufflation-exsufflation. The incidence of acute respiratory failure within 48 hours of extubation was evaluated. Similarly, the reintubation rate, intensive care unit length of stay, mortality at 28 days, and survival probability at 90 days were assessed. The study was stopped after futility results in the interim analysis. Results: We included 122 consecutive patients (n = 61 per group). There was no significant difference in the incidence of acute respiratory failure between treatments (11.5% control group versus 16.4%, intervention group; p = 0.60), the need for reintubation (3.6% versus 10.7%; p = 0.27), mean length of stay (3 versus 4 days; p = 0.33), mortality at Day 28 (9.8% versus 15.0%; p = 0.42), or survival probability at Day 90 (21.3% versus 28.3%; p = 0.41). Conclusion: Mechanical insufflation-exsufflation combined with chest physiotherapy seems to have no impact in preventing postextubation acute respiratory failure in intensive care unit-acquired weakness patients. Similarly, mortality and survival probability were similar in both groups. Nevertheless, given the early termination of the trial, further clinical investigation is strongly recommended. Clinical Trials Register: NCT 01931228

RESUMO Objetivo: Verificar se o uso de insuflação-exsuflação mecânica pode reduzir a incidência da insuficiência respiratória aguda no período de 48 horas pós-extubação em pacientes com fraqueza adquirida em unidades de terapia intensiva. Métodos: Estudo prospectivo, randomizado, controlado e aberto. Os pacientes diagnosticados com fraqueza adquirida em unidade de terapia intensiva foram incluídos consecutivamente, com base em uma pontuação do Medical Research Council ≤ 48/60. Os pacientes receberam aleatoriamente duas sessões diárias; no grupo controle, realizou-se fisioterapia torácica convencional, enquanto no grupo intervenção, combinou-se fisioterapia torácica com insuflação-exsuflação mecânica. Avaliou-se a incidência de insuficiência respiratória aguda dentro de 48 horas após a extubação. Da mesma forma, avaliaram-se a taxa de reintubação, o tempo de permanência na unidade de terapia intensiva, a mortalidade aos 28 dias e a probabilidade de sobrevida aos 90 dias. O estudo foi interrompido após resultados de futilidade na análise intermediária. Resultados: Incluímos 122 pacientes consecutivos (n = 61 por grupo). Não houve diferença significativa na incidência de insuficiência respiratória aguda entre os tratamentos (11,5% no grupo controle versus 16,4% no grupo intervenção; p = 0,60), na necessidade de reintubação (3,6% versus 10,7%; p = 0,27), no tempo médio de internação (3 versus 4 dias; p = 0,33), na mortalidade aos 28 dias (9,8% versus 15,0%; p = 0,42) ou na probabilidade de sobrevida aos 90 dias (21,3% versus 28,3%; p = 0,41). Conclusão: A insuflação-exsuflação mecânica associada à fisioterapia torácica parece não ter impacto na prevenção da insuficiência respiratória aguda pós-extubação em pacientes com fraqueza adquirida na unidade de terapia intensiva. Da mesma forma, a mortalidade e a probabilidade de sobrevida foram semelhantes em ambos os grupos. No entanto, devido ao término precoce do estudo, recomenda-se enfaticamente uma investigação clínica mais aprofundada. Registro Clinical Trials: NCT 01931228

Duchenne muscular dystrophy in a Filipino boy reaching adulthood, and nine years into oral corticosteroids: A case report

Rationale@#Duchenne muscular dystrophy (DMD) is a disease that primarily manifests in the early stages of life and progressively affects muscle strength resulting in quadriparesis and ultimately resulting in premature death secondary to cardiac or respiratory failure. DMD is the most common x-linked genetic disorder in children that is because of an alteration of a protein called “dystrophin” which is responsible for strengthening muscle fibers and protecting them from injury as muscles contract and relax. @*Objective@#To highlight the case of a 19-year-old male who was diagnosed with DMD at 8 years of age and treated with oral corticosteroid and rehabilitation. @*Case@#We present the case of a 19-year-old male who developed difficulty climbing stairs and was diagnosed with DMD at 8 years old with the use of clinical exome sequencing. Corticosteroid therapy was initiated and rehabilitation perpetuated which dramatically improved his life expectancy. @*Discussion and Summary@#Clinical exome sequencing was employed on our patient to confirm the diagnosis of DMD from other neuromuscular and neurodegenerative diseases. Most cases of DMD succumb to cardiopulmonary arrest before reaching adulthood; however, this case exemplifies DMD from other cases since our patient was able to prolong his life with continuation of oral corticosteroid and rehabilitation and in the absence of extensive life support.

Relationship between intestinal microbiota heterogeneity and acquired myasthenia in septic mice / 中华麻醉学杂志

Objective:To evaluate the relationship between intestinal microbiota heterogeneity and acquired myasthenia in septic mice.Methods:Eighty SPF healthy male C57BL/6 mice, weighing 18-20 g, aged 6-8 weeks, were included. Forty mice were selected to prepare a sepsis model by intraperitoneal injection of lipopolysaccharide (LPS) 10 mg/kg. Sepsis-sensitive mice (state of dying or even death within 24 h after developing the model) and sepsis-resistant mice (survival for 7 days and recovery) were screened. The feces from donor mice were collected to make fecal bacteria fluid. Forty mice were selected and divided into 4 groups ( n=10 each) by the random number table method: control group (C group), antibiotic group (ABX group), resistant group (Res group), and sensitive group (Sen group). Group C received no treatment. In ABX group, compound antibiotics were given by intragastric gavage once a day for 5 consecutive days. In Res group, the fecal solution from sepsis-resistant mice 150 μl was given by gavage once a day for 3 consecutive days starting from 5 days after gavage administration of compound antibiotics, and then LPS 15 mg/kg was intraperitoneally injected. In Sen group, the fecal solution from sepsis-sensitive mice was given by gavage for 3 days (using the same method as previously described in Res group) starting from 5 days after gavage administration of compound antibiotics, and then LPS 15 mg/kg was intraperitoneally injected. The severity of sepsis was assessed and scored at 24 h after developing the model. The four limb grip strength was measured after fecal bacteria transplantation and at 24 h after developing the sepsis model. The Compound Muscle Action Potential (CMAP) of the gastrocnemius was measured at 24 h after developing the sepsis model. Then blood samples were collected for determination of the levels of interleukin-1 (IL-1), IL-6 and tumor necrosis factor α (TNF-α) in serum by enzyme-linked immunosorbent assay. The tissues of anterior tibial muscle and gastrocnemius muscle were obtained for determination of the expression of muscle-specific ring finger protein 1 (MuRF-1) and muscle atrophy box F protein (MAFbx) by Western blot. The diameter and cross-sectional area of gastrocnemius muscle fibers were measured after HE staining. The feces of mice were collected at 3 days after fecal bacteria transplantation, and DNA was extracted from mouse fecal samples for 16S rDNA sequencing and untargeted metabolomics analysis. Results:Compared with C group, the score for severity of sepsis was significantly increased, the four limb grip strength was decreased after developing the sepsis model, the serum IL-6 concentration was increased, and the diameter and cross-sectional area of gastnemius muscle fibers were decreased ( P<0.05), and no statistically significant changes were found in the other parameters in Res group, and no statistically significant changes were found in the indexes mentioned above in ABX group ( P>0.05). Compared with C group and Res group, the score for severity of sepsis was significantly increased, the four limb grip strength was decreased, the latency of CMAP was prolonged, and the amplitude of CMAP was decreased, the serum concentrations of IL-1, IL-6 and TNF-α were increased, the diameter and cross-sectional area of gastrocnemius muscle fibers were decreased, and the expression of MuRF-1 and MAFbx in anterior tibial muscle was up-regulated after developing the sepsis model in Sen group ( P<0.05). 16S rDNA sequencing of intestinal flora: Compared with Sen group, no significant change was found in Chao1 index, Good-coverage index and Simpson index in Res group ( P>0.05), Shannon index was increased ( P<0.05), and no significant change was found in β diversity in Res group ( P>0.05). LDA analysis showed that f_Akkermarisiaceae, o_Verrucomicrobiales, g_Akmansia, c_Verrucomicrobiae and p_Verrucomicrobiota were significantly enriched in Sen group, and g_Enterococcus and f_Enterococcaceae were significantly enriched in Res group ( P<0.05). Nontargeted metabolic analysis: The metabolite profiles in Res group and Sen group suggested that the model was well developed (R2Y>Q2Y). Compared with Sen group, 90 metabolites was significantly up-regulated and 88 down-regulated, significantly up-regulated metabolic substances including vitamin K1, gamma-tocopherol, and taurine in Res group ( P<0.05). The differential metabolite KEGG enrichment pathway included 2-oxocarboxylic acid metabolism and ubiquinone and other terpenoid-quinone biosynthesis ( P<0.05). Conclusions:Intestinal flora heterogeneity may be involved in the pathogenesis of acquired myasthenia in septic mice.

Assessment of neuromuscular electrical stimulation in critically ill patients: physical therapists' knowledge and barriers to its use / Avaliação do uso da estimulação elétrica neuromuscular em pacientes críticos: conhecimento dos fisioterapeutas e barreiras à implementação / Evaluación del uso de la electroestimulación neuromuscular en pacientes críticos: conocimiento de los fisioterapeutas y barreras para su implementación

ABSTRACT Transcutaneous neuromuscular electrical stimulation (NMES) is considered an important tool to prevent muscle mass and strength loss in patients admitted to intensive care units (ICU). This study aimed to evaluate physical therapists' profile and knowledge of NMES and identify the main barriers to its use in ICUs. This observational cross-sectional study was conducted via a structured questionnaire created by the authors. It consisted of 12 objective questions to analyze physical therapists' knowledge of NMES use in critically ill patients. Physical therapists were invited to participate in this study during an international symposium on NMES. In total, 56 physical therapists, with a mean age of 33.5±7.2 years and working an average of 9.7±7 years after graduation, completed the survey. Overall, 34 respondents worked in ICUs, of which only four (12%) reported regular NMES use in their ICUs. We found a low average of correct answers to our questionnaire (25%; 3/12). The main barriers reported to using NMES in ICUs were lack of knowledge (28; 50%) and equipment (24; 43%). The number of correct answers expert and non-expert physical therapists was not statistically significant (p=0.68). Thus, we observed participants' poor knowledge of NMES use in critically ill patients. Respondents showed that NMES has been underused in their ICUs. Lack of knowledge and equipment seems to be the main barriers for the use of NMES in ICUs.

RESUMO A estimulação elétrica neuromuscular transcutânea (EENM) é considerada uma importante ferramenta para prevenir a perda de força e massa muscular em pacientes internados em unidades de terapia intensiva (UTIs). Este estudo teve como objetivo avaliar o perfil e conhecimento dos fisioterapeutas sobre a EENM e identificar as principais barreiras para sua utilização na UTI. Foi realizado um estudo observacional transversal, por meio de um questionário estruturado elaborado pelos autores. O questionário foi composto por 12 questões objetivas que visavam analisar o nível de conhecimento dos fisioterapeutas sobre o uso da EENM em pacientes críticos. Os fisioterapeutas foram convidados a participar do estudo durante um simpósio internacional sobre EENM. Cinquenta e seis fisioterapeutas completaram a pesquisa, a média de idade foi de 33,5±7,2 anos e o tempo médio de graduação de 9,7±7 anos. Trinta e quatro entrevistados trabalhavam na UTI, e destes apenas 4 (12%) relataram que a EENM era realizada rotineiramente em suas UTIs. Observou-se baixo nível de conhecimento sobre o uso da EENM em pacientes críticos no questionário, com média de 25% de acertos (3/12). Ao comparar os fisioterapeutas especialistas e não especialistas, o número de acertos não foi estatisticamente significativo (p=0,68). As principais barreiras relatadas para a utilização da técnica foram a falta de conhecimento 28 (50%) e a falta de equipamentos 24 (43%). Os entrevistados demonstraram que a EENM tem sido subutilizada em suas UTIs.

Fuerza de prensión manual. Un sencillo, pero fuerte predictor de salud en población adulta y personas mayores / Handgrip strength as a predictor of adverse health outcomes

Muscle strength can be measured through different methods and handgrip strength is one of the most used techniques in epidemiological studies. Given its easy application, high reliability, and low cost, it is considered an important health biomarker. Handgrip strength is associated with adverse health outcomes such as mortality and risk of developing chronic diseases, cardiovascular, respiratory, cancer and dementia. There is a paucity of evidence in Chile about the association of handgrip strength with these health outcomes limiting its visibility and implementation in clinical settings. Therefore, this narrative review summarizes the scientific evidence about the association of grip strength with non-communicable chronic diseases and mortality in middle age and older adults.

Use of different reference values for handgrip strength in individuals with COPD: analysis of agreement, discriminative capacity, and main clinical implications / Uso de diferentes valores de referência de força de preensão manual em indivíduos com DPOC: análise de concordância, capacidade discriminativa e principais implicações clínicas

ABSTRACT Objective: To identify reference values for handgrip strength through a literature search and compare the agreement of reference values from Brazil with others for handgrip strength in a sample of COPD patients in Brazil, as well as to determine which set of reference values is more discriminative regarding differences in clinical characteristics between individuals with low handgrip strength and normal handgrip strength. Methods: To identify reference values for handgrip strength, a literature search was performed; a retrospective cross-sectional analysis of baseline-only data from two unrelated studies was then performed. Individuals were evaluated for handgrip strength, peripheral muscle strength, respiratory muscle strength, pulmonary function, body composition, exercise capacity, dyspnea, and functional status. Results: Of the 45 studies that were initially selected, 9 met the criteria for inclusion in the analysis, which included 99 COPD patients in Brazil (52% of whom were male with GOLD stage II-IV COPD). The prevalence of low handgrip strength varied across studies (from 9% to 55%), the set of reference values for handgrip strength in a sample of individuals in Brazil having classified 9% of the study sample as having low handgrip strength. The level of agreement between the reference values for a sample of individuals in Brazil and the other sets of reference values varied from weak to excellent. The reference values for a sample of individuals in Brazil showed the highest number of significantly different characteristics between individuals with low and normal handgrip strength. Conclusions: The level of agreement between national and international sets of reference values for handgrip strength varied from weak to excellent in COPD patients in Brazil. Reference values for handgrip strength with higher discriminative capacity are not necessarily those that identify more individuals as having low handgrip strength.

RESUMO Objetivo: Identificar valores de referência de força de preensão manual por meio de pesquisa bibliográfica e comparar, em pacientes com DPOC no Brasil, o nível de concordância entre valores de referência de força de preensão manual obtidos no Brasil com outros valores de referência, bem como determinar qual conjunto de valores de referência é mais discriminativo em relação a características clínicas em indivíduos com força de preensão manual baixa e normal. Métodos: Para identificar valores de referência de força de preensão manual, foi realizada uma pesquisa bibliográfica. Em seguida, foi realizada uma análise transversal retrospectiva de dados exclusivamente basais provenientes de dois estudos não relacionados. Os indivíduos foram avaliados quanto à força de preensão manual, força muscular periférica, força muscular respiratória, função pulmonar, composição corporal, capacidade de exercício, dispneia e estado funcional. Resultados: Dos 45 estudos inicialmente selecionados, 9 preencheram os critérios de inclusão na análise, que incluiu 99 pacientes com DPOC no Brasil (52% dos quais eram homens com DPOC no estágio II-IV da GOLD). A prevalência de força de preensão manual baixa variou entre os estudos (de 9% a 55%), sendo que os valores de referência de força de preensão manual em indivíduos no Brasil classificaram 9% dos pacientes com DPOC como sendo indivíduos com força de preensão manual baixa. O nível de concordância entre os valores de referência para indivíduos no Brasil e os demais valores de referência variou de fraco a excelente. Os valores de referência para indivíduos no Brasil revelaram o maior número de características significativamente diferentes em indivíduos com força de preensão manual baixa e normal. Conclusões: O nível de concordância entre valores de referência nacionais e internacionais de força de preensão manual variou de fraco a excelente em pacientes com DPOC no Brasil. Os valores de referência de força de preensão manual com maior capacidade discriminativa não são necessariamente aqueles que identificam mais indivíduos como sendo indivíduos com força de preensão manual baixa.

Impact of mechanical ventilation time on functional capacity and muscular strength of patients under intensive care / Impacto do tempo de ventilação mecânica na capacidade funcional e força muscular de pacientes em terapia intensiva

Abstract Introduction: A prolonged assisted ventilation (AV) period might induce complications. Objective: To compare functional capacities and muscle strength of patients under AV. Methods: This is a prospective cohort observational study. The patients selected were under mechanical ventilation in any given moment, and they were evaluated only at the time of discharge from the intensive care unit (ICU). The convenience sample of 103 was selected and divided into a group with up to six days of AV (G6) and another with seven days or more of AV (G7). The protocol proposed was: application of the Medical Research Council (MRC) scale, dynamometry, Barthel index, ability to ambulate at ICU discharge. A call was made to the patients six and 12 months after hospital discharge for the application of the Barthel index. Results: We verified that G6 patients obtained better muscular strength measured through right 14 (8-30) and left 18 (8-26) dynamometry and MRC scale 48 (44-56). Only seven (14%) patients from the G7 group were able to ambulate. G7 patients showed greater functional loss at hospital discharge 32 (15-60). After one year of hospital discharge, both groups had recovered their functional capacity 100 (100-100). Conclusion: When evaluating the process of AV, it is possible to conclude that the longer the ventilator is used, the greater the loss of strength and functionality. In addition, there is a significant recovery of functionality after one year of hospital discharge.

Resumo Introdução: Um período prolongado de ventilação assistida (VA) pode induzir complicações. Objetivo: Comparar as capacidades funcionais e a força muscular de pacientes sob VA. Métodos: Trata-se de um estudo observacional de coorte prospectivo. Os pacientes selecionados encontravam-se em ventilação mecânica em qualquer momento, sendo avaliados apenas no momento da alta da unidade de terapia intensiva (UTI). A amostra de conveniência de 103 foi selecionada e dividida em um grupo com até seis dias de VA (G6) e outro com sete dias ou mais de VA (G7). O protocolo proposto foi: aplicação da escala MRC, dinamometria, índice de Barthel, capacidade de deambulação na alta da UTI. Foi feito um chamado aos pacientes seis e 12 meses após a alta hospitalar para aplicação do índice de Barthel. Resultados: Verificamos que os pacientes do G6 obtiveram melhor força muscular medida através da dinamometria direita 14 (8-30) e esquerda 18 (8-26) e escala do MRC 48 (44-56). Apenas sete (14%) pacientes do grupo G7 conseguiram deambular. Os pacientes do G7 apresentaram maior perda funcional na alta hospitalar 32 (15-60). Após um ano da alta hospitalar, ambos os grupos recuperaram sua capacidade funcional 100 (100-100). Conclusão: Ao avaliar o processo de AV, é possível concluir que quanto maior o tempo de uso do ventilador, maior a perda de força e funcionalidade. Além disso, há uma recuperação significativa da funcionalidade após um ano da alta hospitalar.

Anthropometric indicators as predictors of dynapenia in postmenopausal women

Abstract Aim: Anthropometry represents an alternative to the evaluation of nutritional status and screening of events related to muscle fitness. Therefore, this study aimed to compare anthropometric indicators of postmenopausal women with and without dynapenia and to identify the predictive capacity of these indicators to screen the respective outcome in this population. Methods: Cross-sectional epidemiological study, conducted with postmenopausal women. Dynapenia was diagnosed by handgrip strength < 20 kgf. Arm (AC), abdominal (AbC), hip (HC) and calf circumferences (CC), triceps, biceps, subscapular, supraspinatus and thigh skinfolds were analyzed. Body Mass Index, Conicity Index (CI), Body Adiposity Index (BAI), Waist to Hip and Waist to Height Ratio (WHtR), Corrected Arm Muscle Area (CAMA) and Arm Muscle Circumference (AMC) were calculated. Results: A total of 273 women participated in the study. The BAI, WHtR, and CI did not present significant differences between the groups. For the other indicators, the dynapenic group obtained significantly lower values compared to the non-dynapenic. AC was the indicator with the highest sensitivity to screen for postmenopausal dynapenia (79.8%). While CAMA and AMC were the indicators with the best specificity (86.2%). However, CC showed the best balance between sensitivity (67.5%) and specificity (63.0%). Conclusion: The indicators AC, CAMA, and/or the AMC can be used together, or CC alone, to predict postmenopausal women with dynapenia. Therefore, these indicators can be used as important epidemiological tools to improve women's health surveillance actions.

Case Report of a COVID-19 Sub-acute Patient with Rehabilitation Therapy / The Japanese Journal of Rehabilitation Medicine

COVID-19 spread from Wuhan City, People's Republic of China, in December 2019, followed by an explosion of infections worldwide. The number of infected people has also risen dramatically in Japan and has become a major social problem. Patients with severe disease require a long period to return to society due to significant physical weakness even after recovery. We report a patient in his 40s with a history of nephrectomy who was infected with COVID-19 and became critically ill.After being diagnosed with COVID-19 by PCR test, the patient was admitted to our hospital. His respiratory status rapidly worsened and he was temporarily managed by ECMO in the intensive care unit. At the time of his first contact with us (day 31 post-hospitalization), he was unable to hold himself in a standing position for a long time and required a walker. Initially, from the perspective of preventing the spread of infection, we instructed him in self-directed training rather than individual therapy. From day 49, he began to receive physical therapy. He was discharged on day 53 with independence in outdoor walking. He was instructed to consume protein after exercising and he was managed on an outpatient basis. He returned to work. His skeletal muscle mass increased by BIA and his respiratory and motor functions were restored.He received instructions on recovering from severe illness after COVID-19 infection, which focused on nutrition, voluntary training, and monitored individual therapy in accordance with rehabilitation therapy. He was able to return to society with no sequelae.

Osteosarcopenia and trabecular bone score in patients with type 2 diabetes mellitus

ABSTRACT Objective: To evaluate the prevalence of osteosarcopenia and the association of osteosarcopenia with trabecular bone score (TBS) in a group of patients with type 2 diabetes mellitus(T2DMG) compared with a paired control group (CG). Materials and methods: Cross-sectional study with men and women ≥ 50 years recruited by convenience. Patients in both groups answered questionnaires and underwent evaluation of bone mineral density (BMD), handgrip strength (HGS), and TBS. The T2DMG also underwent a gait speed (GS) test. Sarcopenia was defined as low lean mass plus low HGS or GS according to the Foundation for the National Institute of Health Sarcopenia Project, and osteosarcopenia was deemed present when sarcopenia was associated with osteopenia, osteoporosis, or low-energy trauma fractures. Results: The T2DMG (n = 177) and CG (n = 146) had, respectively, mean ages of 65.1 ± 8.2 years and 68.8 ± 11.0 years and 114 (64.4%) and 80 (54.7%) women. T2DMG versus the CG had higher rates of osteosarcopenia (11.9% versus 2.14%, respectively, p = 0.010), sarcopenia (12.9% versus 5.4%, respectively, p < 0.030), and fractures (29.9% versus 18.5%, respectively, p = 0.019), and lower HGS values (24.4 ± 10.3 kg versus 30.9 ± 9.15 kg, respectively, p < 0.001), but comparable BMD values. Mean TBS values were 1.272 ± 0.11 and 1.320 ± 0.12, respectively (p = 0.001). On multivariate analysis, age, greater waist circumference, fractures, and osteoporosis increased the risk of degraded TBS. Osteosarcopenia was associated with diabetes complications (p = 0.03), calcium and vitamin D supplementation (p = 0.01), and all components of osteosarcopenia diagnosis (p < 0.05). Conclusion: Compared with the CG, the T2DMG had a higher prevalence of osteosarcopenia, sarcopenia, and fractures and lower bone quality assessed by TBS.
