RESUMO

PURPOSE/AIM: Anterior cruciate ligament injuries are the most common traumatic ligament injuries of the knee, which course with impaired balance. The aim of the present study was to analyse the effect of kinesiology tape on balance in subjects with non-operated anterior cruciate ligament rupture. MATERIALS AND METHODS: 36 subjects were randomly assigned to the kinesiology tape group (KT = 20) and the non-standardized tape group (NST = 16). Balance was assessed in the following 3 conditions: no bandage, immediately after application, and after four days of use. The outcome measures used were the Sensory Organisation Test (SOT), assessed by computerised dynamic Posturography (CDP), the modified star excursion balance test (mSEBT), the Spanish version of the KOOS and the Lysholm Knee Score. A 2-way repeated measures analysis of variance (ANOVA) was performed, with time as a within-subject factor and group as a between-subjects factor. Bonferroni correction was applied when the ANOVA was significant. RESULTS: ANOVA showed that there was no significant interaction between group and time for all outcome measures. However, a significant effect on the time factor was observed for: composite SOT score in both groups immediately after tape application; composite SOT after four days of use in the KT group; mSEBT in the KT group immediately after tape application. The KOOS improved in both groups after four days of tape use, while the Lysholm Knee Score improved only in the NST group. CONCLUSIONS: No differences were observed between the KT or NST groups in balance measurements.

RESUMO

OBJECTIVE: To examine the immediate and prolonged effects (7d) of Kinesiology Tape (KT) on balance in subjects with chronic ankle instability using computerized dynamic posturography (CDP). DESIGN: A 7-day follow-up, single-blind randomized controlled trial. SETTING: University community. PARTICIPANTS: Subjects (N=36) were screened for possible eligibility criteria, and 30 successfully completed the study protocol. Of these, 15 were randomly assigned to the experimental group (KT: 5 men, 10 women), and 15 were assigned to the control group (placebo tape: 10 men, 5 women). INTERVENTIONS: The experimental group was taped for a lateral ankle sprain with KT. In the control group, a placebo tape was used. Balance was assessed under the following 3 conditions: without taping, immediately after application, and after 7 days of use. MAIN OUTCOME MEASURES: The CDP device used in this study was the Smart Equitest version 8.2. CDP analysis was conducted using the Sensory Organization Test (SOT). As primaries outcome measures, the composite SOT score and composite SOT strategy were chosen. The partial score for SOT condition 2 and its strategy were considered as the secondary outcomes measures. RESULTS: Repeated-measures analysis of variance (ANOVA) demonstrated that there was not a significant interaction between group and time in the composite SOT score (F=.239; P=.73), SOT condition 2 (F=.333; P=.705), and SOT strategy 2 (F=.899; P=.43). Additionally, repeated-measures ANOVA showed a significant effect for time (composite SOT score: F=40.69; P≤.01; SOT condition 2: F=4.61; P=.014; SOT strategy 2: F=.899; P=.413; composite SOT strategy: F=15.14; P≤.01). Specifically, post hoc analysis showed that both groups obtained improvements in composite SOT scores immediately after tape application and 7 days of use. CONCLUSIONS: According to our results, the SOT scores of both the KT and control groups improved during follow-up. No differences between them were observed during the follow-up in most balance measurements. The observed changes may be related to a subjective increase in confidence after the tape application.

RESUMO

This study evaluates the degree of empathy among medical students and its influencing factors at three critical moments of their degree studies (beginning of first year and end of third and sixth years) as well as establishes low-, medium-, and high-empathy cut-off points to obtain valid and reliable results that can be extrapolated to the general population. This cross-sectional study of the eight (public and private) medical schools in the province of Madrid, used an electronic questionnaire with the Jefferson Scale of Empathy (JSE), Medical Student Well-Being Index, and other independent characteristics as measuring instruments. Of the 2,264 student participants, 1,679 (74.0%) were women, with a 50.7% participation rate. No significant differences were found in empathy levels by academic year. Regarding range, percentile and cut-off point tables were established to identify students with high, medium, and low empathy levels. Women (p<0.001), volunteer workers (p<0.001), and those preferring general specialties (internal medicine, psychiatry, pediatrics, or family medicine) scored higher on the JSE (p<0.02). Moreover, 41.6% presented high level of psychological distress. Women reported a lower well-being level and a higher risk of psychological distress (p = 0.004). In sum, the empathy of medical students in Madrid did not differ among the three critical moments of their university studies. The established cut-off points could be taken into account when accessing the medical degree and identifying students with low levels of empathy to implement curricular interventions to rectify this perceived deficiency. There was a high percentage of medical students with high levels of psychological distress.

RESUMO

To analyze the effect of a computer-aided static navigation technique and mixed reality technology on the accuracy of orthodontic micro-screw placement. Material and methods: Two hundred and seven orthodontic micro-screws were placed using either a computer-aided static navigation technique (NAV), a mixed reality device (MR), or a conventional freehand technique (FHT). Accuracy across different dental sectors was also analyzed. CBCT and intraoral scans were taken both prior to and following orthodontic micro-screw placement. The deviation angle and horizontal deviation were then analyzed; these measurements were taken at the coronal entry point and apical endpoint between the planned and performed orthodontic micro-screws. In addition, any complications resulting from micro-screw placement, such as spot perforations, were also analyzed across all dental sectors. Results: The statistical analysis showed significant differences between study groups with regard to the coronal entry-point (p < 0.001). The NAV study group showed statistically significant differences from the FHT (p < 0.001) and MR study groups (p < 0.001) at the apical end-point (p < 0.001), and the FHT group found significant differences from the angular deviations of the NAV (p < 0.001) and MR study groups deviations (p = 0.0011). Different dental sectors also differed significantly. (p < 0.001) Additionally, twelve root perforations were observed in the FHT group, while there were no root perforations in the NAV group. Conclusions: Computer-aided static navigation technique enable more accurate orthodontic micro-screw placement and fewer intraoperative complications when compared with the mixed reality technology and conventional freehand techniques.

RESUMO

PURPOSE: To report the immediate and prolonged (one week) effects of elastic bandage (EB) on balance control in subjects with chronic ankle instability. MATERIAL AND METHODS: Twenty-eight individuals successfully completed the study protocol, of whom 14 were randomly assigned to the EB group (7 men, 7 women) and 14 were assigned to the non-standardised tape (NST) group (9 men, 5 women). To objectively measure postural sway we used computerised dynamic posturography (CDP) with sensory organisation test (SOT) and unilateral stance (US) test. We analysed the following SOT parameters: the composite SOT score, the composite SOT strategy and the SOT condition 2 and its strategy. In addition, we studied the centre of gravity (COG) sway velocity with open eyes and close eyes during the US test. RESULTS: Repeated measures ANOVA showed a significant effect for time in composite SOT score (F= 34.98; p= <0.01), composite SOT strategy (F= 12.082; p= 0.02), and COG sway with open eyes (F= 3.382; p= 0.039) in EB group and NST group. Therefore, there were improvements in balance control after bandage applications (defined as better scores in SOT parameters and decreased COG sway in US test). However, no differences between groups were observed in the most relevant parameters. CONCLUSIONS: This study did not observe differences between EB and NST during the follow-up in the majority of measurements. Several outcome measures for SOT and US tests improved in both groups immediately after bandage applications and after one week of use. EB of the ankle joint has no advantage as compared to the non-standardised tape. Implications for rehabilitation Elastic bandage (EB) of the ankle joint has no advantage as compared to the non-standardised tape. The effects of the bandages could be due to a greater subjective sense of security. It is important to be prudent with the use of bandage, since a greater sense of safety could also bring with it a greater risk of injury. The application of the bandage on subjects with chronic ankle instability (CAI) should be prolonged and used alongside other physiotherapy treatments.

RESUMO

BACKGROUND: Corticosteroid infiltration (CI) is commonly used for treatment of plantar fasciosis. In recent years, however, interest has grown in the use of intratissue percutaneous electrolysis (EPI) for the treatment of tendinopathies. The aim of our study was to compare the effectiveness of the above techniques in the treatment of plantar fasciosis. METHODS: The results achieved over a period of 1 year following the use of these techniques to treat plantar fasciosis were examined. There were 64 patients; 32 of whom were treated with ultrasound-guided EPI and 32 with ultrasound-guided CI. A clinical examination was performed and ultrasound taken before treatment and at 3, 6, and 12 months. Clinical assessments were made using a visual analog scale (VAS) to record pain and the Foot and Ankle Disability Index (FADI) to evaluate function. Ultrasound was used to determine the thickness of the plantar fascia. RESULTS: Both the ultrasound-guided EPI and CI techniques were associated with significant clinical and echographic improvements at 12 months post-treatment ( P < .001). CONCLUSION: Both techniques were effective in the treatment of PF, providing excellent VAS pain and FADI results at 12 months. However, CI required fewer patient visits and appeared to provide somewhat better VAS and FADI results. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

RESUMO

Resumen Introducción: Durante la actual pandemia de COVID-19 múltiples complicaciones se han desarrollado posterior a la enfermedad, dentro de las cuales se encuentran las infecciones fúngicas, como la mucormicosis, que puede resultar directamente de la infección por COVID-19 y/o como efecto secundario de los fármacos utilizados en su tratamiento. La mucormicosis es una infección causada por un grupo de hongos llamados mucormycetes; a nivel rinocerebral se presenta con celulitis facial, cefalea, proptosis, movilización del diente afectado y secreción nasal. Reporte de caso: Se presenta a un paciente femenino de 57 años con antecedente de neumonía grave por COVID-19 con posterior desarrollo de absceso periodontal que ameritó extracción del segundo molar superior derecho con posterior formación de fistula. Se toma TC de macizo facial donde se evidencia erosión ósea con pérdida de la morfología habitual y en pared anterior del seno maxilar derecho. Se realiza biopsia reportando tejido óseo con elementos micóticos (hifas aseptadas) morfológicamente compatibles con mucor sp. Se realizó tratamiento con anfotericina B y hemimaxilectomia derecha. Actualmente se encuentra en tratamiento con pozaconazol, y lavados quirúrgicos. Conclusión: La enfermedad de COVID-19 es una enfermedad muy común actualmente a nivel mundial, por lo que es importante identificar y llevar un seguimiento de aquellas personas con factores de riesgo para desarrollar mucormicosis; el diagnóstico y un plan de tratamiento temprano es fundamental para evitar complicaciones, las cuales pueden originar un desenlace fatal.


Abstract Introduction: During the current pandemic of COVID-19 multiple complications have developed after the disease, among which are fungal infections, such as mucormycosis, which can result directly from COVID-19 infection and/or as a side effect of the drugs used in its treatment. Mucormycosis is an infection caused by a group of fungi called mucormycetes; at the rhinocerebral level it presents with facial cellulitis, headache, proptosis, mobilization of the affected tooth and nasal secretion. Case report: the following is a 57-year-old female patient with a history of severe pneumonia due to COVID-19 with subsequent development of periodontal abscess that merited extraction of the upper right second molar with subsequent fistula formation. The patient started an infection with the presence of purulent secretion in the extraction area of the right molar. A CT scan of the facial mass was taken showing bone erosion with loss of the usual morphology in the right upper maxillary bone and anterior wall of the right maxillary sinus, as well as a biopsy of the right maxilla reporting bone tissue with mycotic elements (aseptates hyphae) morphologically compatible with mucor sp. Treatment with amphotericin B and right hemimaxillectomy was performed. She is currently being treated with pozaconazole and surgical washings. Conclusion: COVID-19 disease is currently a very common disease worldwide, so it is important to identify and follow up those people with risk factors for developing mucormycosis; early diagnosis and treatment plan is essential to avoid complications, which can lead to a fatal outcome.

RESUMO

Securin is a chaperone protein with bifunctional properties. It binds to separase to inhibit premature sister chromatid separation until the onset of anaphase, and it also takes part in cell-cycle arrest after UV irradiation. At metaphase-to-anaphase transition, securin is targeted for proteasomal destruction by the anaphase-promoting complex or cyclosome (APC/C), allowing activation of separase. However, although securin is reported to undergo proteasome-dependent degradation after UV irradiation, the ubiquitin ligase responsible for securin ubiquitylation has not been well characterized. In this study, we show that UV radiation induced a marked reduction of securin in both the nucleus and cytoplasm. Moreover, we show that GSK-3beta inhibitors prevent securin degradation, and that CUL1 and betaTrCP are involved in this depletion. We also confirmed that SKP1-CUL1-betaTrCP (SCF(betaTrCP)) ubiquitylates securin in vivo, and identified a conserved and unconventional betaTrCP recognition motif (DDAYPE) in the securin primary amino acid sequence of humans, nonhuman primates and rodents. Furthermore, downregulation of betaTrCP caused an accumulation of securin in non-irradiated cells. We conclude that SCF(betaTrCP) is the E3 ubiquitin ligase responsible for securin degradation after UV irradiation, and that it is involved in securin turnover in nonstressed cells.
