INTRODUCTION: The internal representation of verticality could be disturbed when a lesion in the central nervous system (CNS) affects the centers where information from the vestibular, visual, and/or somatosensory systems, increasing the risk of falling. OBJECTIVE: The aim was to evaluate the vestibular and somatosensory contribution to the verticality pattern in patients with stroke and other neurological disorders. METHODS: A literature search was performed in PubMed, Scopus, Web of Science, and CINAHL databases. Cross-sectional, case-control, and cohort studies comparing body verticality in patients with stroke or CNS diseases (CNSD) versus healthy controls were selected. Subjective postural vertical (SPV) in roll and pitch planes was used as the primary variable. RESULTS: Ten studies reporting data from 390 subjects were included. The overall effect for CNSD patients showed a misperception of body verticality in roll (standardized mean difference [SMD] = 1.05; 95% confidence interval [CI] .84-1.25) and pitch planes (SMD = 1.03; 95% CI .51-1.55). In subgroup analyses, a high effect was observed in the perception of SPV both in roll and pitch planes in stroke (p = .002) and other CNSD (p < .001). CONCLUSION: These findings suggest a potential misperception of SPV in patients with stroke and other neurological disturbances. Patients with CNSD could present an alteration of vestibular and somatosensory contribution to verticality construction, particularly stroke patients with pusher syndrome (PS), followed by those with PS combined with hemineglect.

Dry needling (DN) is an invasive physiotherapy technique employed for reducing myofascial pain. To compare the effectiveness of dry needling (DN) versus manual therapy (MT) in improving pain, active maximal mouth opening (AMMO) and cervical disability in patients with myofascial pain from temporomandibular disorders (TMDs) were investigated against these treatments. A single-blind, randomized controlled trial was carried out. Individuals (n = 50) with TMDs were randomly allocated in a 1:1 ratio to the DN (n = 25) or MT group (n = 25). Each group received three sessions, separated by 4 days, of either DN or MT. Outcomes were assessed according to pain intensity (Numeric Pain Rating Scale), AMMO (cm), disability (Neck Disability Index), and pressure-pain threshold (PPT) (digital algometry) from the active myofascial trigger points. In both groups, pain and neck disability were significantly lower at the end of treatment compared with those measured at baseline (pain: -2.52 with 95% CI: -3.43 to -1.60 for DN group; pain: -2.92 with 95% CI: -3.77 to -2.07 for MT group; disability: -3.2 with 95% CI: -4.31 to -2.09 for DN group; disability: -2.68 with 95% CI: -3.56 to -1.79 for MT group), but not were not lower after the first session, without differences between the groups. AMMO was significantly higher after the first session (0.16 with 95% CI: 0.03 to 0.29 for DN group; 0.30 with 95% CI: 0.20 to 0.41 for MT group) and at the end of treatment in both groups (0.27 with 95% CI: 0.14 to 0.41 for DN group; 0.37 with 95% CI: 0.22 to 0.52 for MT group) compared with the baseline measurements. Finally, PPT results for the masseter and pterygoid muscles were significantly higher at the end of treatment in both groups (without statistically significant differences between groups), but not after the first session. The assessed therapies, DN and MT, are equally effective in improving pain, AMMO, cervical disability, and PPT in the muscles directly involved in the temporomandibular joint biomechanics of patients with myofascial TMDs.

The aim of our meta-analysis was to compile the available evidence to evaluate the effect of physical exercise-based therapy (PEBT) on pain, impact of the disease, quality of life (QoL) and anxiety in patients with fibromyalgia syndrome (FMS), to determine the effect of different modes of physical exercise-based therapy, and the most effective dose of physical exercise-based therapy for improving each outcome. A systematic review and meta-analysis was carried out. The PubMed (MEDLINE), SCOPUS, Web of Science, CINAHL Complete and Physiotherapy Evidence Database (PEDro) databases were searched up to November 2022. Randomized controlled trials (RCTs) comparing the effects of physical exercise-based therapy and other treatments on pain, the impact of the disease, QoL and/or anxiety in patients with FMS were included. The standardized mean difference (SMD) and a 95% CI were estimated for all the outcome measures using random effect models. Three reviewers independently extracted data and assessed the risk of bias using the PEDro scale. Sixty-eight RCTs involving 5,474 participants were included. Selection, detection and performance biases were the most identified. In comparison to other therapies, at immediate assessment, physical exercise-based therapy was effective at improving pain [SMD-0.62 (95%CI, -0.78 to -0.46)], the impact of the disease [SMD-0.52 (95%CI, -0.67 to -0.36)], the physical [SMD 0.51 (95%CI, 0.33 to 0.69)] and mental dimensions of QoL [SMD 0.48 (95%CI, 0.29 to 0.67)], and the anxiety [SMD-0.36 (95%CI, -0.49 to -0.25)]. The most effective dose of physical exercise-based therapy for reducing pain was 21-40 sessions [SMD-0.83 (95%CI, 1.1--0.56)], 3 sessions/week [SMD-0.82 (95%CI, -1.2--0.48)] and 61-90 min per session [SMD-1.08 (95%CI, -1.55--0.62)]. The effect of PEBT on pain reduction was maintained up to 12 weeks [SMD-0.74 (95%CI, -1.03--0.45)]. Among patients with FMS, PEBT (including circuit-based exercises or exercise movement techniques) is effective at reducing pain, the impact of the disease and anxiety as well as increasing QoL.

BACKGROUND: Kahoot! is an educational tool allowing teachers to create a series of gamified tests with the aim of reinforcing educational content, thus improving the teaching-learning process. The objective of this project is to evaluate the acquisition of content through gamified tests with Kahoot! and reward cards compared to the traditional teaching methodology (contents not reinforced). METHODS: This Physiotherapy Teaching Innovation Project (PTIP) was carried out in four subjects of the Degree in Physiotherapy at the University of Jaén (Spain). The teachers responsible for each subject were instructed in the use of Kahoot! and reward cards. These teachers randomly selected the contents that were going to be reinforced with Kahoot! while the other 50% of the contents would not be reinforced. In the final exam of each subject, the results related to the reinforced contents were compared with those non-reinforced and the degree of satisfaction of the students with the experience was evaluated. RESULTS: A total of 313 students participated in this PTIP. In all subjects, we determined a significant increase in the number of correct answers in an improvement range from 7% (95% CI 3.85 to 9.38) to more than 20% (95% CI 17.61 to 26.86) in favor of the questions that alluded to reinforced content using Kahoot! compared to the non-reinforced contents. More than 90% of the participants considered the use of Kahoot! useful and motivating. Our findings showed that Kahoot! motivated more than 65% of students to study daily. CONCLUSIONS: The students obtained better academic results in the questions related to contents reinforced with tests through Kahoot! and reward cards compared to those non-reinforced, showing that this methodology can be an effective tool to promote retention and content assimilation.

Digital and interactive health interventions (DIHIs), such as virtual-reality-based therapy (VRBT) and smartphone-app-based therapy (SABT), may be useful for reducing the impact of the signs and symptoms of breast cancer (BC) in women. The aim of this meta-analysis was to explore the effect of DIHIs on improving pain, anxiety, depression, quality of life (QoL), and upper extremity (UE) disability-related lymphedema in women with BC. METHODS: We searched PubMed Medline, Web of Science, Scopus, CINAHL, Physiotherapy Evidence Database, and SciELO for the period ending February 2022. We included studies that assessed the effect of DIHIs on UE motor disability, pain, anxiety, depression, and QoL in women with BC. The effect size was calculated using Cohen's standardized mean difference (SMD) and its 95% confidence interval (95% CI). RESULTS: Twenty studies providing data from 1613 women with BC were included. With respect to UE disability, DIHIs increased flexion (SMD, 1.92; 95%CI: -1.16, 2.68), abduction (SMD, 1.66; 95%CI: 0.91, 2.42), external rotation shoulder range of motion (SMD, 1.1; 95%CI: 0.36, 1.85), UE function (SMD, -0.72; 95%CI: -1.31, -0.13), and handgrip strength (SMD, 0.4; 95%CI: 0.21, 0.59). DIHIs reduced pain (SMD, -0.8; 95%CI: -1.31, -0.26), anxiety (SMD, -1.02; 95%CI: -1.71, -0.34), and depression (SMD, -1.57; 95%CI: -3.1, -0.08). Finally, DIHIs increased overall health (SMD, 0.6; 95%CI: 0.31, 0.89). CONCLUSIONS: Right at the end of therapy, DIHIs are effective at improving UE function, pain, anxiety, depression, and QoL in women with BC. VRBT has a greater effect than SABT for the assessed outcomes.

Balance problems are one of the most frequent symptoms in patients with Fibromyalgia Syndrome (FMS). However, the extent and nature of this balance disorder are not known. The objective of this work was to determine the best evidence for the alteration of postural balance in patients with FMS and analyze differences with healthy controls. To meet this objective, a systematic review with meta-analysis was performed. A bibliographical search was carried out in PubMed Medline, Scopus, Web of Science, CINAHL and SciELO. Observational studies that assessed postural balance in patients with FMS compared to healthy subjects in baseline conditions, were selected. In a random-effect model, the pooled effect was calculated with the Standardized Mean Difference (SMD) and its 95% confidence interval (CI). Nineteen studies reporting data of 2347 participants (95% female) were included. FMS patients showed poor balance with a large effect on static (SMD = 1.578; 95% CI = 1.164, 1.992), dynamic (SMD = 0.946; 95% CI = 0.598, 1.294), functional balance (SMD = 1.138; 95% CI = 0.689, 1.588) and on balance confidence (SMD = 1.194; 95% CI = 0.914, 1.473). Analysis of the Sensory Organization Test showed large alteration of vestibular (SMD = 1.631; 95% CI = 0.467, 2.795) and visual scores (SMD = 1.317; 95% CI = 0.153, 2.481) compared to healthy controls. Patients with FMS showed worse scores for different measures of postural balance compared to healthy controls. Concretely, FMS patients appear to have poor vestibular and visual scores with a possible somatosensory dependence.

INTRODUCTION: frequently after kidney transplantation there is an increase in weight with a resulting high percent of obesity in these recipients. This combined with a rapid loss of bone mass, a higher prevalence of osteoporosis and fractures is evident than in normal populations. OBJECTIVES: to explore the relationship between body mass index (BMI) and prevalence of osteoporosis in a population of renal transplant recipients. METHODS: prospective longitudinal study design. The study was conducted on 306 kidney transplant recipients. The relationship between weigh and body mass index with femoral and lumbar osteopenia and osteoporosis prevalence at the moment of transplant and at 12 months post was explored. RESULTS: there was a high prevalence of overweight (35.6%) and obese (14.1%) recipients after renal transplant and 1 year after (42.2% and 24.2% respectively). Significant differences were found(p = 0.049) between the weight at the time of transplant and the presence of osteopenia or osteoporosis at the lumbar level one year after, the highest weights were in recipients with osteoporosis. The mean BMI was higher (p = 0.028) in osteoporotic patients (26.59 kg/m2) than in patients with osteopenia (24.23 kg/m2). CONCLUSION: results seem to be consistent with recent studies in the general population showing excessive weight as a possible factor detrimental to the bone health.


Introducción y objetivos: tras el trasplante renal es frecuente un aumento de peso, así como un elevado porcentaje de obesidad en estos pacientes. Por otro lado, tras el trasplante se produce una pérdida de la masa ósea, siendo la prevalencia de osteoporosis y fracturas óseas mayor que en la población general. Objetivos: explorar la relación entre el índice de masa corporal y la prevalencia de osteopenia y osteoporosis en una población de trasplantados renales. Material y método: estudio longitudinal prospectivo sobre una muestra de 306 trasplantados renales. Se exploraron las relaciones entre el peso y el índice de masa corporal con la prevalencia de osteopenia y osteoporosis a nivel femoral y lumbar en el momento del trasplante y a los 12 meses del mismo. Resultados: se halló una alta prevalencia de sobrepeso (35,6%) y obesidad (14,1%) tras el trasplante renal y al año del mismo (42,2% y 24,2%, respectivamente). Se hallaron diferencias estadísticamente significativas (p = 0,049) entre el peso en el momento del trasplante y la presencia de osteopenia u osteoporosis al año del mismo a nivel lumbar, siendo el peso medio más elevado entre los pacientes con osteoporosis. La media del IMC fue más elevada (p = 0,028) en los pacientes osteoporóticos (26,59 kg/m2) que en los pacientes con osteopenia (24,23 kg/m2). Conclusiones: nuestros resultados parecen estar en concordancia con recientes estudios realizados en la población general, que muestran el sobrepeso como un posible factor perjudicial para el hueso.

SbmA is an inner membrane protein of Gram-negative bacteria that is involved in the internalization of glycopeptides and prokaryotic and eukaryotic antimicrobial peptides, as well as of peptide nucleic acid (PNA) oligomers. The SbmA homolog BacA is required for the development of Sinorhizobium meliloti bacteroids within plant cells and favors chronic infections with Brucella abortus and Mycobacterium tuberculosis in mice. Here, we investigated functional features of SbmA/BacA using the proline-rich antimicrobial peptide Bac7(1-35) as a substrate. Circular dichroism and affinity chromatography studies were used to investigate the ability of SbmA to bind the peptide, and a whole-cell transport assay with fluorescently labeled peptide allowed the determination of transport kinetic parameters with a calculated Km value of 6.95 ± 0.89 µM peptide and a Vmax of 53.91 ± 3.17 nmol/min/mg SbmA. Use of a bacterial two-hybrid system coupled to SEC-MALLS (size exclusion chromatography coupled with multiangle laser light scattering) analyses established that SbmA is a homodimer in the membrane, and treatment of the cells with arsenate or ionophores indicated that the peptide transport mediated by SbmA is driven by the electrochemical gradient. Overall, these results shed light on the SbmA-mediated internalization of peptide substrates and suggest that the transport of an unknown substrate(s) represents the function of this protein.

Objetivo: Estudiar la relación entre función renal, medidas por la fórmula de Cockcroft-Gault(CG) y por la tasa de filtración glomerular estimada por la modificación de la dieta en enfermedad renal (MDRD) y la densidad mineral ósea (DMO), en pacientes postransplante renal. Pacientes y método: La muestra estuvo formada por 310 pacientes transplantados, 194 hombres y 116 mujeres, a los que se le realizó medición de la densidad mineral ósea en columna lumbar, cuello de fémur y radio distal mediante absorciometría dual de Rx (DXA) y estimación de la función renal por los métodos de CG y MDRD y determinaciones de índice de masa corporal (IMC). Resultados: Las medias de DMO y de los filtrados CG y MDRD, aumentan del sexto mes al primer año de trasplante, en pacientes con DMO normal, disminuye en la osteopenia y aumentan en osteoporosis. Las mediciones del IMC presentaron una alta correlación con el filtrado CG al sexto mes de transplante (r = 0,222 P < 0,001) y al año (r = 0,258 P < 0,001). Conclusiones: Las fórmulas de CG y MDRD, presentan una alta asociación con la densidad mineral ósea, pero solo la función renal medida por CG es un predictor importante de la pérdida ósea.


Background and objective: To study the relationship between measures of renal function and bone mineral density (BMD) to determine which measure of renal function by Cockcroft-Gault (CG) and estimated glomerular filtration rate by modification of diet in renal disease (MDRD), is more strongly associated with bone mineral density(BMI). Patients and Methods: The sample consisted of 310 patients transplanted, 194 men and 116 women, which underwent measurement of bone mineral density in lumbar spine, femur and radioulnar Rx dual absorptiometry (DXA) and renal function estimation by CG and MDRD methods and measurements of body mass index (BMI) Results: Mean bone mineral density and the CG and MDRD filtered, increase after 6 months the first year of transplantation in patients with normal bone mineral density, decreases in osteopenia and osteoporosis increases. BMI measurements were highly correlated with CG filtering the sixth month of transplantation (r = 0.222 p <0.001) and year (r = 0.258 p <0.001). Conclusions: Cockcroft-Gault (CG) and glomerular filtration rate estimated by the Modification of Diet in Renal Disease (MDRD) showed a high association with bone mineral density, but just the renal function as measured by CG is a predictor significant bone loss and fractures.

Fundamento: Las alteraciones en el metabolismo mineral óseo representan una causa importante de morbilidad y mortalidad en los pacientes con insuficiencia renal crónica en hemodiálisis (IRC). La disminución de masa ósea y el riesgo de fracturas son un hallazgo frecuente. Diferentes factores explican esta disminución de masa ósea; entre ellos los relacionados con sus valores antropométricos. El objetivo de este trabajo es conocer el comportamiento de la densidad mineral ósea frente al peso y talla utilizando el índice de masa corporal (IMC) de pacientes con Enfermedad Renal Crónica (ERC) y tratamiento en hemodiálisis. Material y métodos: Se estudió la densidad mineral ósea (DMO), mediciones T-score y Z-score en cuello de fémur, trocánter, intertrocánter, 1/3 proximal fémur, triangulo de Ward´s, L2, L3 y L4, usando densitometría DXA y la composición corporal en 73 pacientes (40 hombres y 33 mujeres) en hemodiálisis. Resultados: El tiempo total en diálisis de estos pacientes fue para las mujeres 9,7 ± 5,54 años y para los varones 10,18 ± 7,16 años. Como grupo los pacientes mostraron una correlación positiva muy significativa entre el DMO y el peso, la altura y el IMC, las fracturas, el tiempo en diálisis y la PTH intacta. Conclusiones: Los pacientes con ERC en programa de hemodiálisis periódica, muestran una reducción significativa de la DMO, que afecta tanto a columna lumbar como fémur. El peso y la talla influyen sobre la DMO y sobre el recambio óseo, factores muy importantes de predicción de riesgo de fractura. El IMC es el principal determinante de DMO (AU)


Background: Alterations in bone mineral metabolism represent an important cause of morbidity and mortality in patients with chronic renal failure on haemodialysis, the decrease in bone mass and fracture risk are a common finding, there are several factors that explain this decrease in bone mass, including those associated with anthropometric values. The aim of this study was to analyze bone mineral density versus height and weight using the body mass index (BMI) of patients with chronic kidney disease (CKD) and haemodialysis treatment. Material and methods: We studied bone mineral density (BMD) measurements T-score and Z-score at femoral neck, trochanter, intertrochanter, 1 / 3 proximal femur, Ward?s triangle, L2, L3 and L4, using DXA densitometry and body composition in 73 patients (40 men and 33 women) on haemodialysis. Results: duration on dialysis was 9.7 ± 5.54 years for women and 10.18 ± 7.16 years for men. As a group the patients showed a significant positive correlation between BMD and weight, height, and BMI, fractures, time on dialysis and intact PTH. Conclusions: Patients with CKD on haemodialysis program show a significant reduction in BMD, which affects both lumbar spine and femur. The weight and size influence on BMD and bone turnover, important factors for predicting fracture risk. BMI is the main determinant of BMD (AU)
