Comparison of distance covered, physiological cost, and perceived exertion in four six-minute walk test protocols.

Objective: There is evidence that indicates that the Walked Distance (WD) in the 6-Minute Walk Test (6MWT) would be sensitive to the type of track and encouragement. The aim of study was compared the impact of track type and verbal encouragement provided in the 6MWT on WD, physiological cost, perceived exertion, and gait efficiency in healthy young adults unfamiliar with the test. Method: WD, heart rate, subjective sensation of dyspnea (SSD), and fatigue (SSF) were measured in four 6MWT protocols: i) 30 m linear track and protocolized encouragement (LT + PE), ii) 30 m linear track and constant encouragement (LT + CE), iii) 81 m elliptical track and protocolized encouragement (ET + PE), and iv) 81 m elliptical track and constant encouragement (ET + CE). In addition, the Gait Efficiency Index (GIE) associated with physiological cost, dyspnea and fatigue was calculated and compared between the different protocols. Results: The WD was significantly higher in the ET + CE protocol. The percentage of the heart rate reserve used (%HRRu) at minute 6 was higher in the ET + CE protocol. The SSD and SSD had difference in startup time between the protocols. The GEI was higher in %HRRu, SSD, and SSF for the ET + CE protocol. Conclusion: The ET + CE protocol showed a significant increase in WD during the 6MWT in healthy young adults. Although it obtained the highest physiological cost, it did not present perceptual differences when entering cardiopulmonary assessment windows relevant to a more efficient test for the participant. It is advisable to discuss, based on the findings, the fundamental objective of the 6MWT and national and international recommendations to achieve a result as close as possible to the real maximal effort.

Scapulohumeral Spaces: Concordance and Proposal for Terminologia Anatomica

SUMMARY: The updating of anatomical terms is essential to facilitate teaching and learning as well as international communication through publications and presentations at scientific events. In the posterior wall of the axilla, the teres major, teres minor and triceps brachii muscles form three spaces through which neurovascular structures of clinical significance run. The current study seeks to define and propose terms for these spaces which have been omitted by Terminologia Anatomica. The definition of the Latin term 'Spatium' was investigated using A Latin Dicionary, while the term 'Espacio' was analyzed using Diccionario panhispánico de términos médicos (Real Academia Nacional de Medicina de España, 2023), as well as the lexemes of the words 'scapula' and 'humerus', for which the Diccionario Médico-Biológico, Histórico y Etimológico de la Universidad de Salamanca was consulted. The presence of the term 'Spatium' in the Terminologia Anatomica was also investigated. Finally, 10 anatomy textbooks in Spanish were reviewed to identify the terms used for these spaces. In reviewing the latest edition of Terminologia Anatomica, it was found that the term 'Spatium' appears 25 times in different chapters and it was evident that no terms for scapulohumeral spaces appear in the chapters on upper limb structures. Moreover, in 100 % of the anatomy textbooks reviewed, at least one term is used to describe the scapulohumeral spaces. We believe that the proposed terms: 'Spatium humerotricipitale', 'Spatium scapulotricipitale' and 'Spatium teretricipitale' more accurately describe both the location and their association with the bone/muscle structures that form them. We therefore suggest that these terms be revised for inclusion in future editions of Terminologia Anatomica.

La actualización de términos anatómicos es esencial para facilitar la enseñanza-aprendizaje y comunicación internacional a través de publicaciones y presentaciones en eventos científicos. En la pared posterior de la axila, los músculos redondo mayor, redondo menor y tríceps braquial, forman tres espacios por donde discurren estructuras neurovasculares relevantes en la clínica. El estudio tuvo como objetivo definir y proponer términos para estos espacios omitidos por Terminologia Anatomica. En el diccionario A Latin Dictionary se investigó la definición en latín del término 'Spatium' y 'Espacio' en el Diccionario panhispánico de términos médicos (Real Academia Nacional de Medicina de España, 2023), además de los lexemas de las palabras 'escápula' y 'húmero' en el Diccionario Médico-Biológico, Histórico y Etimológico de la Universidad de Salamanca. También se investigó la presencia del término 'Spatium' en la Terminologia Anatomica. Por último, se revisaron 10 libros-textos de anatomía en español para identificar los términos utilizados para estos espacios y su relevancia clínica. Al revisar la última edición de Terminologia Anatomica, se observó que el término 'Spatium' aparece 25 veces en distintos capítulos y se evidenció que no aparecen términos para los espacios escapulohumerales en los capítulos de miembro superior. Además, en el 100 % de los libros-textos de anatomía revisados, se utiliza al menos un término para describir a los espacios escapulohumerales. Consideramos que los términos propuestos: 'Spatium humerotricipitale', 'Spatium scapulotricipitale' y 'Spatium teretricipitale' aluden con mayor precisión a la ubicación, ya que relaciona a las estructuras óseas y/ o musculares que lo forman. Por lo que sugerimos que estos términos sean revisados para incluirlos en futuras ediciones de Terminologia Anatomica.

A pulmonary rehabilitation program is an effective strategy to improve forced vital capacity, muscle strength, and functional exercise capacity similarly in adults and older people with post-severe COVID-19 who required mechanical ventilation.

BACKGROUND: It is internationally known that our population is aging. At the same time, some patients with COVID-19, due to their symptoms, required mechanical ventilation (MV) and subsequent pulmonary rehabilitation (PR). This study aimed to compare the effects of a multimodal PR program "ADULT" versus "OLDER" people with COVID-19 who were on MV. METHODS: The intervention consisted of an 8-week hybrid PR program (2x week). Forced vital capacity (FVC) was measured at the beginning and end of PR, upper and lower limb strength was obtained through hand grip strength (HGS) and the sit-to-stand test (STST), respectively, and functional exercise capacity was measured with the 6-minute walking test (6MWT). RESULTS: The main results were an increase in the FVC in the ADULT and OLDER groups (time effect, P = 0.000; η2 = 0.27), an increase in HGS in the ADULT and OLDER groups (time effect, P = 0.000; η2 = 0.52), in the same way, the number of repetitions on the STST increased in the ADULT and OLDER groups (time effect, P = 0.000; η2 = 0.55). Finally, the distance covered on the 6MWT increased in the ADULT and OLDER groups (time effect, P = 0.000; η2 = 0.65). CONCLUSIONS: The PR program is an effective strategy to improve FVC, muscle strength, and functional exercise capacity similarly in adults and older people with post severe COVID-19 who required MV.

Effects of a pulmonary rehabilitation program on pulmonary function, exercise performance, and quality of life in patients with severe COVID-19.

BACKGROUND: Severe coronavirus 2019 disease (COVID-19) causes acute hypoxemic respiratory failure requiring invasive mechanical ventilation (IMV). Once these symptoms are resolved, patients can present systemic deterioration. OBJECTIVE: The two objectives of this study were as follows: to describe the results of a pulmonary rehabilitation program (PRP), which is divided into three groups with different numbers of sessions (12, 24, and 36), and to associate the variables of pulmonary function, exercise performance, and functionality with the number of sessions and functional improvement. DESIGN: Prospective, observational study. METHODS: PRP consisted of aerobic + strength + flexibility exercises under the supervision and individualized into 12, 24, or 36 sessions (12s, 24s, and 36s), depending on the evolution of each patient. At the beginning of the study and immediately after the intervention, forced vital capacity (FVC), maximal inspiratory pressure, 6-minute walk test (6MWT), sit-to-stand test (STS), maximal handgrip strength (HGS), Fatigue Assessment Scale, Post-COVID-19 Functional Status (PCFS), and health-related quality of life (HRQoL) were measured. RESULTS: The proposed PRP demonstrated a positive effect on pulmonary function, exercise performance, and HRQoL, regardless of the number of sessions. A higher score on the PCFS and more days on IMV were associated with the increased likelihood of needing more sessions, whereas more meters on the 6MWT in the initial evaluation was associated with a reduced likelihood of needing more sessions. Finally, more repetitions on the STS and less distance covered on the initial 6MWT were associated with a greater improvement in exercise performance evaluated with the 6MWT. CONCLUSION: Supervised and individualized PRP for patients with severe post-COVID-19 improves pulmonary function, exercise performance, functionality, and quality of life. Functionality, distance covered on the 6MWT, and the days on IMV are central to the scheduling of the number of sessions for these patients.

Effectiveness of assisted standing on bone mineral density in children with cerebral palsy. A systematic review. / Efectividad de la bipedestación asistida en la densidad mineral ósea, en niños con parálisis cerebral. Una revisión sistemática.

Cerebral palsy is associated with complications such as low bone mineral density, which is more severe in patients with greater motor involvement. Assisted standing helps to prevent or delay this complication; however, its effect is controversial because the type of stander, the type of standing (dynamic or static), and its dosage are not clear. The objective of this study was to determine the effectiveness of assisted standing on bone mineral density in children with cerebral palsy. A systematic review was carried out in compliance with the PRISMA guidelines, using 5 databases. The results were presented using tables, a risk of bias analysis, and a narrative synthesis. Four studies met the inclusion criteria. Assisted standing generates positive changes in bone mineral density, but further research is required, with studies that have greater methodological rigor, longer follow-up periods, and a larger number of patients.

La parálisis cerebral tiene complicaciones asociadas como una baja densidad mineral ósea; esta es más acentuada a mayor compromiso motor. La bipedestación asistida ayuda a prevenir y/o a retrasar esta complicación, aunque su efecto es controversial, porque no está claro el tipo de bipedestador, el tipo de bipedestación (dinámica o estática) ni su dosificación. El objetivo de este estudio es determinar la efectividad de la bipedestación asistida en la densidad mineral ósea, en niños con parálisis cerebral. Se realizó una revisión sistemática bajo los lineamientos PRISMA, se utilizaron cinco bases de datos. Los resultados se presentaron a través de tablas, análisis de riesgo de sesgo y síntesis narrativa. Cuatro estudios cumplieron los criterios de inclusión. La bipedestación asistida genera cambios positivos en la densidad mineral ósea, pero se necesita más investigación, con estudios que tengan un mayor rigor metodológico, períodos de seguimiento más largos y que incluyan una mayor cantidad de pacientes.

Neuron parvum fluorescens, un Término con Influencia Anglo-Greco-Latina. Propuesta a Terminologia Neuroanatomica y Terminologia Histologica / Neuron Parvum Fluorescens, a Term with Anglo-Greco-Latin Influence. A Proposal to Terminologia Neuroanatomica and Terminologia Histologica

Las terminologías son utilizadas como instrumento lingüístico que permite la transmisión de conocimiento de manera precisa y sin ambigüedades en el ámbito de las ciencias. Los lineamientos de la Federative International Programme for Anatomical Terminology (FIPAT) refieren que la denominación de nombres estructurales debe ser descriptivos e informativos. Este estudio analiza las raíces lingüísticas que componen el término Neuron parvum valde fluorescens vigente en Terminologia Histologica y el término Neuron parvum fluorescens vigente en Terminologia Neuroanatomica. Las células pequeñas intensamente fluorescentes son neuronas que se encuentran en el sistema nervioso autónomo, distribuidas en los ganglios simpáticos. Estas células presentan sinapsis aferentes con terminales nerviosas simpáticas preganglionares y sinapsis eferentes con las dendritas de las neuronas posganglionares. Su función es regular la transmisión ganglionar, actuando como interneuronas con señalización paracrina y endocrina. Además, se caracterizan por ser células fluorescentes, que expresan catecolaminas; serotonina, noradrenalina y dopamina. Se realizó una búsqueda en Terminologia Histologica y Terminologia Neuroanatomica, con una traducción de los términos al español. Además, la búsqueda se complementó en un diccionario etimológico en inglés para los términos correspondientes. Esta investigación encontró diferencia entre la traducción del latín al español del término fluorescens, quien posee un origen etimológico muy diferente a su significado en español. El término Neuron parvum valde fluorescens en Terminologia Histologica y el término Neuron parvum fluorescens en Terminologia Neuroanatomica, identifican a la misma estructura. Se sugiere reemplazar ambos términos por Cateconeuron ganglionare, entregando así una correcta descripción de este tipo de neurona, considerando su ubicación y función. Además, de esta manera ser un término concordante en latín para su incorporación en Terminologia Neuroanatomica y Terminologia Histologica.

SUMMARY: Terminologies are used as a linguistic tool to convey knowledge in a precise and unambiguous manner in science. The guidelines of the Federative International Programme for Anatomical Terminology (FIPAT) state that the names given to structures should be both descriptive and informative. This study analyses the linguistic roots of the term Neuron parvum valde fluorescens in Terminologia Histologica and the term Neuron parvum fluorescens in Terminologia Neuroanatomica. Small intensely fluorescent cells are neurons found in the autonomic nervous system, distributed in the sympathetic ganglia, they have afferent synapses with preganglionic sympathetic nerve terminals and efferent synapses with the dendrites of postganglionic neurons, whose function is to regulate ganglionic transmission, acting as interneurons with paracrine and endocrine signalling. They are also characterized as fluorescent cells, producing the catecholamines: serotonin, noradrenaline and dopamine. A search was carried out in Terminologia Histologica and Terminologia Neuroanatomica, with a translation of the terms into Spanish. This was complemented by a search in an English etymological dictionary for the corresponding terms. This research found a difference between the Latin to English translation of the term fluorescens, which has a very different etymological origin to its English meaning. The term Neuron parvum valde fluorescens in Terminologia Histologica and the term Neuron parvum fluorescens in Terminologia Neuroanatomica identify the same structure. The proposal is to replace both terms with Cateconeuron ganglionare, thus affording an accurate description of this type of neuron, considering its location and function. Moreover, it would also be a concordant term in Latin for its incorporation into the Terminologia Neuroanatomica and Terminologia Histologica.

Influencia de Factores Psicológicos en el Pronóstico de Individuos con Artroplastia de Cadera por Artrosis: una Revisión de la Literatura / Influence of Psychological Factors on the Prognosis of Individuals with Hip Arthroplasty for Osteoarthritis: A Review of the Literature

Introducción. Los factores psicológicos preoperatorios pueden influir en los resultados de la rehabilitación de la artroplastia de cadera por artrosis. No existe consenso de cuáles serían estos factores, ni sobre en qué medidas de resultados influirían. Objetivo. Sintetizar la evidencia respecto a los factores psicológicos que pronostican los resultados de la artroplastía de cadera en términos de función física y dolor en individuos con artrosis de cadera. Métodos. Se efectuó una búsqueda en PUBMED, EMBASE, SCOPUS y CINAHL. Los términos incluyeron artroplastia de cadera, artrosis, factores psicológicos, función física y dolor. Se incorporaron estudios observacionales prospectivos. Los resultados se agruparon por factor psicológico en periodos menor a un año e igual o mayor a un año. Resultados. La búsqueda arrojó 895 artículos, dos cumplieron los criterios de elegibilidad. Los resultados descritos fueron: 1) un mayor nivel de expectativas preoperatorias genera un efecto positivo en la disminución de la intensidad de dolor y 2) tiene un efecto positivo en la función física, ambas a menos de un año, y 3) la depresión preoperatoria genera un efecto negativo en la disminución de intensidad de dolor a un año o más. Conclusiones. La presencia de depresión preoperatoria se asoció a una menor reducción de dolor, y las altas expectativas preoperatorias se asociaron con una mejor función física y una menor intensidad de dolor. Sin embargo, se hace necesaria la generación de nueva evidencia científica que profundice en la asociación factores psicológicos preoperatorios y dolor crónico en esta población.

Background. Preoperative psychological factors may influence the results of hip arthroplasty rehabilitation for osteoarthritis. There is no consensus on what these factors would be, nor on what outcome measures they would influence. Objetive. To review was to synthesize the evidence regarding psychological factors that predict hip arthroplasty outcomes in terms of physical function and pain in individuals with hip osteoarthritis. Methods. A search was carried out in PUBMED, EMBASE, SCOPUS and CINAHL. Terms included hip arthroplasty, osteoarthritis, psychological factors, physical function, and pain. Prospective observational studies were incorporated. The results were grouped by psychological factor in periods of less than one year and equal to or greater than one year. Results. The search yielded 895 articles, two met the eligibility criteria. The results described were: 1) a higher level of preoperative expectations generates a positive effect in the reduction of pain intensity and 2) has a positive effect on physical function, both at less than one year, and 3) preoperative depression generates a negative effect in the reduction of pain intensity at one year or more. Conclusions. The presence of preoperative depression was associated with less pain reduction, and high preoperative expectations were associated with better physical function and less pain intensity. However, it is necessary to generate new scientific evidence that deepens the association of preoperative psychological factors and chronic pain in this population.
