Effectiveness of Blood Flow Restriction on Functionality, Quality of Life and Pain in Patients with Neuromusculoskeletal Pathologies: A Systematic Review

Background: Blood flow restriction is characterized as a method used during exercise at low loads of around 20–40% of a repetition maximum, or at a low-moderate intensity of aerobic exercise, in which cuffs that occlude the proximal part of the extremities can partially reduce arterial flow and fully restrict the venous flow of the musculature in order to achieve the same benefits as high-load exercise. Objective: The main objective of this systematic literature review was to analyze the effects of BFR intervention on pain, functionality, and quality of life in subjects with neuromusculoskeletal pathologies. Methods: The search to carry out was performed in PubMed, Cochrane, EMBASE, PEDro, CINHAL, SPORTDiscus, Trip Medical Database, and Scopus: “kaatsu” OR “ischemic training” OR “blood flow restriction” OR “occlusion resistance training” OR “vascular occlusion” OR “vascular restriction”. Results: After identifying 486 papers and eliminating 175 of them due to duplication and 261 after reading the title and abstract, 50 papers were selected. Of all the selected articles, 28 were excluded for not presenting a score equal to or higher than 6 points on the PEDro scale and 8 for not analyzing the target outcome variables. Finally, 14 papers were selected for this systematic review. Conclusions: The data collected indicate that the blood flow restriction tool is a therapeutic alternative due to its effectiveness under different exercise modalities. The benefits found include decreases in pain thresholds and improvement in the functionality and quality of life of the neuro-musculoskeletal patient during the first six weeks. However, the results provided by this tool are still not clear for medium- and long-term interventions.Partial funding for open access charge: Universidad de Málag

Spanish Cross-Cultural Adaptation and Validation of Neck Bournemouth Questionnaire (NBQ) for Neck Pain Patients.

Background: Neck pain is highly prevalent and one of the most common musculoskeletal conditions. Instruments that measure the factors involved in neck pain accurately are needed for clinical assessment. Patient-reported outcome measures (PROMs) are reliable, cost-effective, and specific tools for the assessment of musculoskeletal problems at different moments. The Neck Bournemouth Questionnaire (NBQ) assesses pain, function, disability, and psychological and social variables in patients with cervical pathologies. The aim of this study was to perform an adaptation and validation into Spanish of the NBQ (NBQ-Sp). Methods: A cross-sectional, observational study was carried out through translation, adaptation, and validation. A total of 129 patients with neck pain, of Spanish nationality, and over 18 years of age were included. Results: The NBQ-Sp showed excellent internal consistency, with Cronbach’s of 0.897, test–retest reliability with interclass correlation coefficient (ICC) of 0.866, and standard error of measurement (SEM) and minimum detectable change (MDC) values were 1.302 and 3.038, respectively. A Kaiser–Meyer–Olkin value of 0.857 was obtained, and Bartlett’s test yielded p < 0.001, finding one factor in the factor analysis. Conclusion: The NBQ-Sp has proven to be a valid and reliable tool for clinicians and researchers to measure neck pain in the Spanish population.Partial funding for open access charge: Universidad de Málag

Spanish cross-cultural adaptation and validation of the Oslo Sports Trauma Research Centre (OSTRC) Overuse Injury Questionnaire in Handball Players.

Objectives: The aim of this study was the cultural adaptation, Spanish translation and validation of the Oslo Sports Trauma Research Centre (OSTRC) Overuse Injury Questionnaire in an adult population. Design: In this study, a cross-sectional design was used. Methods: This study was divided into two phases: (1) cross-cultural adaptation of the original version of the OSTRC to a Spanish version (OSTRC-Sp) and (2) analysis of the psychometric properties of the OSTRC-Sp. A total of 427 handball players of both sexes and over 18 years of age participated in the study. Results: The translated version of the questionnaire showed a very high internal consistency (Cronbach’s α = 0.954), while the subscales showed an internal consistency between 0.832 and 0.961, with the endmost values being for shoulder and low back pain, respectively. On the other hand, when analysing item responses, the OSTRC-Sp showed ICC values ranging from 0.844 to 0.956, the former being for the first back question (back_1), and the latter for the fourth shoulder question (shoulder_4), in line with most published versions. Conclusion: The Spanish version of the OSTRC is a reliable and valid tool that can be used by researchers and clinicians in a Spanish-speaking population with musculoskeletal disorders

An escape room game-based innovation for the assessment of physiotherapy students: A qualitative study

Background: Classic assessment methods present negative emotional alterations for students, such as stress, anxiety, fear and nervousness; these could be solved by applying the Escape Room, which is a promising tool where students experience positive emotions that are critical to learning. Aim: To explore the experiences and perceptions of physiotherapy students regarding the use of an Escape Room game-based model for their assessment in contrast to conventional approaches. Methods: A phenomenological-hermeneutical study was conducted. The assessment took place in two different modalities and on different days: 1) a traditional assessment method and 2) an assessment method incorporating a game-based model. All students participated in the two assessment processes. Fifty-six physiotherapy students took part in this study. Results: The detailed analysis of the results allowed us to classify them into two main themes: 1) Strengths of the Escape Room as part of an assessment approach and, 2) Weaknesses of the Escape Room as part of an assessment approach. In turn, from these main themes emerged the sub-themes and their different units of meaning. Conclusions: The results suggest that new teaching and assessment methodologies incorporating innovative models such as the Escape Room are effective in evaluating the skills and performance of physiotherapy students, which can be used to complement the traditional assessment methods

Efecto de la triploidía sobre los parámetros musculares y nutricionales del rodaballo (Scophthalmus maximus, L.) después de su maduración sexual

Con el objetivo de una mejor comprensión de la calidad final del rodaballo triploide (Scophtha/mus maximus, L.), la celularidad musculary los parámetros de calidad de la carne fueron estudiados en 7 rodaballos diploides y 7 lriploides de 33 meses de edad, todos ejemplares decultivoy de un tamaño similar. La celularidad del músculo blanco se evaluó por medio del número y diámetro de las fibras musculares. Para determinarla calidad de la carne fueron analizados diversos parámetros físico-químicos (humedad, proteína, grasa y ácidos grasas totales) y se determinaIOO las propiedades mecánicas de la lextura (dureza, elasticidad, masticabilidad, cohe~ividad y gomosidad) con un texturómetro. El mecanismode crecimiento muscular difirió entre los dos grupos, de tal manera que el tamaño de las fibras fue mayor (p<O,OOI)en los triploides , mientrasquela densidad de fibras musculares fue mayor en el grupo de los diploides, lo que demuestra que las diferencias genéticas produjeron dtlerente celularidad muscular en ambos grupos. No se encontraron diferencias significativas en las propiedades texturales ni en los parámetros decalidad de la carne entre diploides y triploides.In order lo a beller understanding of Ihe final qualily of lriploid turbot (Scophthalmus maximus, L.), muscle cellularily and qualily parametersoflhe flesh were studied on 7 diploid and 7 triploid 33 months old farmed turbot of similar size. White muscle cellularily was evaluated by meansofIhe number and diameter of muscle fibers. lo ascertain the flesh qualily, several physlco-cbemlcal parameters (moisture, protein, total fat andfalty acids) were analyzed, and textural mechanical properties (hardness, springiness, chewiness, cohesiveness, gumminess) were determinedwitha texturometer. Muscle growth mechanism differed between both groups, such that muscie fibres size was greater (p<O,OOI)in triploid specimens, wihereas muscle fibre density was higher in diploid group, thus showing mat genetic differences produced different muscie cellularity in bothgroups. No significant differences were found in textural properties and flesh qualily parameters between diploid and triploid groups

Physical Therapists’ Opinion of E-Health Treatment of Chronic Low Back Pain

1) Background: Using new technologies to manage home exercise programmes is an approach that allows more patients to benefit from therapy. The objective of this study is to explore physical therapists’ opinions of the efficacy and disadvantages of implementing a web-based telerehabilitation programme for treating chronic low back pain (CLBP). (2) Methods: Nineteen physical therapists from academic and healthcare fields in both the public and private sector participated in the qualitative study. Texts extracted from a transcript of semi-structured, individual, in-depth interviews with each consenting participant were analysed to obtain the participants’ prevailing opinions. The interviews lasted approximately 40 min each. The participants’ responses were recorded. (3) Results: The results suggest that telerehabilitation can only be successful if patients become actively involved in their own treatment. However, exercise programmes for LBP are not always adapted to patient preferences. New technologies allow physical therapists to provide their patients with the follow-up and remote contact they demand, but long-term adherence to treatment stems from knowledge of the exercises and the correct techniques employed by the patients themselves. (4) Conclusions: Physical therapists treating patients with chronic non-specific low back pain believe that new technologies can provide highly effective means of reaching a greater number of patients and achieving significant savings in healthcare costs, despite the limitations of a telerehabilitation approach in developing an appropriate and effective patient-based physiotherapy programme

Evaluation of cytokines as robust diagnostic biomarkers for COVID-19 detection

Producción CientíficaAntigen tests or polymerase chain reaction (PCR) amplification are currently COVID-19 diagnostic tools. However, developing complementary diagnosis tools is mandatory. Thus, we performed a plasma cytokine array in COVID-19 patients to identify novel diagnostic biomarkers. A discovery–validation study in two independent prospective cohorts was performed. The discovery cohort included 136 COVID-19 and non-COVID-19 patients recruited consecutively from 24 March to 11 April 2020. Forty-five cytokines’ quantification by the MAGPIX system (Luminex Corp., Austin, TX, USA) was performed in plasma samples. The validation cohort included 117 patients recruited consecutively from 15 to 25 April 2020 for validating results by ELISA. COVID-19 patients showed different levels of multiple cytokines compared to non-COVID-19 patients. A single chemokine, IP-10, accurately identified COVID-19 patients who required hospital admission (AUC: 0.962; 95%CI (0.933–0.992); p < 0.001)). The results were validated in an independent cohort by multivariable analysis (OR: 25.573; 95%CI (8.127–80.469); p < 0.001) and AUROC (AUC: 0.900; 95%CI (0.846–0.954); p < 0.001). Moreover, showing IP-10 plasma levels over 173.35 pg/mL identified COVID-19 with higher sensitivity (86.20%) than the first SARS-CoV-2 PCR. Our discover–validation study identified IP-10 as a robust biomarker in clinical practice for COVID-19 diagnosis at hospital. Therefore, IP-10 could be used as a complementary tool in clinical practice, especially in emergency departments.Instituto de Salud Carlos III (grant COV20/00491)Consejo Superior de Investigaciones científicas (grant CSIC-COV19-016/202020E155)Junta de Castilla y León (project COVID 07.04.467B04.74011.0)IBGM excellence programme (grant CLU-2029-02

Resultados preliminares de la influencia de la temperatura de cultivo sobre la proporción de sexos en el rodaballo (Scophthalmus maximus L.)

Las larvas de tres familias de rodaballos se cultivaron a temperaturas de 15'C, 18'C y 22'C desde el día dos hasta día 90 de vida y a temperatura ambiente hasta el dia 210. En las familias 1 y 2 las proporciones sexuales, determinadas por el fenotipo, oscilaron en los tres grupos entre el 40%- 60%,y no se observaron diferencias siqníñcaffvas entre los diferentes grupos de temperatura (p>0.05). En la familia 3, el porcentaje de hembras fue mayor que el de machos en los tres grupos de temperatura, y además se observó diferencia significativa (p<0.05) entre el grupo de peces cultivados a temperatura fría con respecto a los cultivados en agua ambiente. En tas familias 1 y 2 el sexo genético coincidió en gran medida con~ sexo fenolípico, siendo la discrepancia menor del 10%. Sin embargo, en la familia 3 se observó que el 36,5% de los machos genéticos eran hembras a 15'C, el 29% a 18ºC y el 18% a 23'C. Los resultados sugieren la interacción temperatura-familia en la determinación sexual del rodaballo, que debe ser confirmada en un mayor número de familias.Larvae from three families of turbot were cultured at 15'C, 18'C and 22'C from 2 to 90 days old, and then at ambient temperature until210 daysold.
