RESUMO

Objective To cross-culturally validate the Health Mindset Scale for Brazil, as well as adapt the terms and questionnaires for adequate understanding of Brazilians, using factor analysis as an instrument to validate its reliability. Methods Cross-cultural validation of the Health Mindset Scale into Brazilian Portuguese using the Beaton method, Cronbach's alpha calculation and factor analysis Results The sample consisted of 215 patients aged between 18 and 87 years (M = 41.98; SD = 15.72), with a mean age between 31 and 50 years (42.0%), and female (52 .6%), a marginally significant difference (p < 0.10) between men and women was observed for item 3. In this item, men's mean (M = 5.48; SD = 0.99) was higher than the average for women (M = 5.10; SD = 1.22), with a small effect size for the difference (d = 0.26). Pearson's r correlation coefficient was examined between the mean score and age (r = -0.21; p = 0.002), the result of which indicated a weak, negative and significant linear relationship. The older the age, the lower the average score on the Health Mindset Scale. Conclusion The version of the health-focused mindset scale for Brazilian Portuguese was introduced and cross-culturally validated, demonstrating good reliability with a Cronbach's alpha of 0.786. Consequently, it constitutes a new instrument for clinical practice and can be correlated with established scales in the literature.

RESUMO

Objective The Body Image Disturbance Questionnaire for Scoliosis (BIDQ-S) for scoliosis derives from the Body Image Disturbance Questionnaire (BIDQ) with specific adaptation for scoliosis patients. Despite its significance and applicability, this instrument has never been translated into Brazilian Portuguese. The current study aimed to translate, transculturally adapt, and validate the BIDQ-S into Brazilian Portuguese. Methods BIDQ-S was translated and culturally adapted into Brazilian Portuguese using the American Association of Orthopedic Surgeons (AAOS) criteria. The questionnaire validation relied on internal consistency and comparison with the Cobb angle, Pediatric Quality of Life Inventory (PedsQL), and Scoliosis Research Society (SRS-22). The Brazilian version (BR-)BIDQ-S validation occurred in a sample of 35 adolescents with scoliosis waiting for specialized treatment. Results Internal consistency of the BR-BIDQ-S was 0.899 according to the Cronbach's index (i.e., virtually perfect). Although BR-BIDQ-S did not correlate with the Cobb angle, it presented correlations with the Physical, Emotional, and Social domains from the PedsQL and the Function/Activity domain from the SRS-22. Conclusion BR-BIDQ-S was reliable in evaluating the body image of adolescents with scoliosis, presenting an internal consistency of 0,899 (virtually perfect). Moreover, similar to the original instrument, it correlated with PedsQL and SRS-22.

RESUMO

Scoliosis is a pathology with multiple etiologies that leads to aesthetic changes, increased morbidity and, especially, psychological damage. Objective: This work aims to compare two mindset types (fixed and growth) and assess levels of quality of life in individuals with scoliosis. Methods: Two questionnaires, Scoliosis Research Society-30 (SRS-30) and Early-Onset Scoliosis-24 Questionnaire (EOSQ-24), associated with the "Health Mindset Scale," were used. We applied the SRS-30 to patients who were independent or whose diagnosis of spinal deformity occurred after the age of 10 years. For patients diagnosed before the age of 10 or who presented dependence due to cognitive impairment, caregivers were subjected to the "Health Mindset Scale" and EOSQ-24 questionnaires. Results: The sample consisted of 35 patients aged from 4 to 46 years, the majority aged from 15 to 18 years old (42.9%), female (71.4%), and with neuromuscular scoliosis (28.6%). The only significant result (p = 0.060) was the increase in pain/discomfort scores in the EOSQ-24 for a patient with a growth mindset. Lastly, there was no statistical difference between groups, however, in patients with a growth mindset, there was a tendency (p = 0.060) to have a higher pain/discomfort score, assessed via the EOSQ-24 score, reported by the caregiver. Level of Evidence III, Retrospective Comparative Study.

A escoliose é uma patologia com múltiplas etiologias e que acarreta alterações estéticas, aumento de morbidade e principalmente danos psicológicos. Objetivo: Comparar dois tipos de mindset (fixo e construtivo) e o nível de qualidade de vida. Métodos: Foram utilizados dois questionários, o Scoliosis Research Society-30 (SRS-30) e o Early-Onset Scoliosis-24 Questionnaire (EOSQ-24), associados à escala Health Mindset Scale. Aplicamos o SRS-30 em pacientes independentes ou cujo diagnóstico de deformidade na coluna ocorreu após os 10 anos. Já no caso de pacientes com diagnóstico antes dos 10 anos ou que apresentassem dependência devido a dificuldades cognitivas, os cuidadores foram submetidos à Health Mindset Scale e ao EOSQ-24. Resultados: A amostra foi composta por 35 pacientes com idades entre 4 e 46 anos, sendo a maioria entre 15 e 18 anos (42,9%), do sexo feminino (71,4%) e com escoliose do tipo neuromuscular (28,6%). O único resultado com significância (p = 0,060) foi o aumento dos escores de dor/desconforto nos questionários EOSQ-24 em paciente com mindset de crescimento. Por fim, não houve diferença estatisticamente significante entre os grupos, porém, em pacientes com mindset construtivo, houve tendência (p = 0,060) de maior escore de dor/desconforto avaliado por meio do EOSQ-24 e referido pelo cuidador. Nível de Evidência III, Estudo Retrospectivo Comparativo.

RESUMO

BACKGROUND: Low back pain (LBP) has a high economic burden and is strongly related to the degenerative process of the spine, especially in the intervertebral disc and of the facet joints. Numerous treatment modalities have been proposed for the management of LBP, and the use of platelet-rich plasma (PRP) has emerged as an innovative therapeutic option for degenerative disease of the spine. The present study aims to evaluate the efficacy of PRP injections in managing low back pain. METHODS: We conducted a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, a registered at PROSPERO Systematic Reviews Platform, under number CRD42021268491. The PubMed, Web of Science, and Scopus databases were searched to identify relevant articles, along with hand searching to identify gray literature articles, with no language restrictions. Randomized clinical trials (RCTs), nonrandomized trials (NRTs), and case series (CSs) with more than 10 patients were considered eligible. The quality assessment and the risk of bias of the randomized clinical trials were evaluated using the RoB II tool. An evaluation of the description of the preparation methods was performed using an adapted version of the MIBO checklist. RESULTS: An electronic database search resulted in 2324 articles, and after the exclusion of noneligible articles, 13 RCTs and 27 NRTs or CSs were analyzed. Of the 13 RCTs, 11 found favorable results in comparison to the control group in pain and disability, one showed no superiority to the control group, and one was discontinued because of the lack of therapeutic effect at eight-week evaluation. Description of the PRP preparation techniques were found in almost all papers. The overall risk of bias was considered high in 2 papers and low in 11. An adapted MIBO checklist showed a 72.7% compliance rate in the selected areas. CONCLUSIONS: In this systematic review, we analyzed articles from English, Spanish and Russian language, from large databases and grey literature. PRP was in general an effective and safe treatment for degenerative LPB. Positive results were found in almost studies, a small number of adverse events were related, the risk of bias of the RCTs was low. Based on the evaluation of the included studies, we graded as level II the quality of the evidence supporting the use of PRP in LBP. Large-scale, multicenter RCTs are still needed to confirm these findings.

RESUMO

BACKGROUND: Assessing the quality of life (QOL) of children with early onset scoliosis (EOS) has been discussed recently. Therefore, the study aimed to apply and correlate the 24-item Early Onset Scoliosis Questionnaire (EOSQ-24) with the 50-item Childhood Health Questionnaire (CHQ-PF50) to find predictive factors impacting QOL. METHODS: Cross-sectional study involving a population of caregivers of patients with EOS. The sample consisted of 72 patients. Two research assistants applied the Portuguese version of the EOSQ-24 and CHQ-PF50 in 3 treatment centers. The EOSQ-24 assesses the subjective response of children with EOS from the parent's point of view. The CHQ is a self-administered questionnaire or parental proxy assessment of the psychological and social status of children aged 5 to 18 years. RESULTS: Of 72 patients, 41 (56.9%) were females, mean age of 11.9 ± 4.2 years. The most common scoliosis was of neuromuscular origin (32%). The CHQ-PF50 showed that family-related items had significant scores. The most affected subcategory was physical function (45.5), and the least affected was mental health (90.8). Thus, the CHQ-PF50 PhS summary index was 27, and the CHQ-PF50 PsS was 71.7. Moreover, the critical categories for the EOSQ-24 questionnaire were daily life and physical function (45.1 and 47.8, respectively), and the least affected categories were transfer and pulmonary function (70.8 and 68.9, respectively). Four subcategories showed a strong correlation between both questionnaires: general health (r = 0.749, P < 0.001), physical function (r = 0.645, P < 0.001), bodily pain (r = 0.714, P < 0.001), and mental health (r = 0.424, P < 0.001). Using CHQ-PF50 as a dependent variable in multiple regression analysis (P = 0.028), the only variable affecting the scores was syndromic scoliosis (P = 0.019; 95% CI -27.4 to -2.5). CONCLUSION: A strong correlation between both questionnaires was seen for general health, physical function, bodily pain, and mental health. Syndromic scoliosis was a predictor of worse QOL according to the CHQ-PF50.

RESUMO

Objectives: To present the functional outcomes, through the first case series in our country, of patients with thoracolumbar burst fractures (A3,A4), submitted to short posterior fixation, without arthrodesis and without removal of the implants, until the end of the minimum follow-up of one year. Methods: Fifty five patients consecutively treated between January/2010 and January/2019 were evaluated through medical records and imaging exams. Radiographic analysis was performed by mea suring local and segmental kyphosis using the Cobb method. Functional assessment was analyzed using the non-specific SF-36 questionnaire and the 1983 Denis pain and work-specific questionnaire, applied after 12 months of follow-up. Results: With a loss of five patients (9%), 22 (44%) patients reported having minimal and occasional pain and 8 (16%) patients reported having no pain. Three (6%) patients responded that they were completely incapacitated. Patients had a mean score of 73.16 points in the SF-36 domains. There was a significant reduction in kyphosis in 12 months (9.1±5.2 [min-max 0-22]) compared to the preoperative period (14.9±7.8 [min-max 0-32]) ( p≤0.01). One patient required implant removal due to the symptomatic prominence of the implant. Conclusion: This case series suggests that the technique leads to satisfactory functional results, without implant failure or significant kyphosis after a minimum follow-up of 12 months of treatment. Evidence Level IV; Case series.

Objetivo: Apresentar os desfechos funcionais, mediante primeira série de casos no nosso meio, de pacientes com fratura toracolombar do tipo explosão (A3, A4), submetidos a fixação posterior curta, sem artrodese e sem retirada dos implantes, até o final do acompanhamento mínimo de um ano. Métodos: Foram avaliados, por meio de prontuários e exames de imagem, 55 pacientes consecutivamente tratados entre Janeiro/2010 e Janeiro/2019. A análise radiográfica foi realizada medindo a cifose local e segmentar, pelo método de Cobb. A avaliação funcional analisada por meio do questionário inespecífico SF-36 e questionário específico de dor e trabalho de Denis de 1983, aplicados após os 12 meses de seguimento. Resultados: Com perda de cinco pacientes (9%), 22 (44%) pacientes relataram ter dor mínima e ocasional e 8 (16%) pacientes responderam não ter dor. Três (6%) pacientes responderam que estavam completamente incapacitados. Os pacientes tiveram uma pontuação média de 73,16 pontos nos domínios do SF-36. Houve redução significativa da cifose em 12 meses (9,1±5,2 [min-máx 0-22]) na comparação com o pré-operatório (14,9±7,8 [min-máx 0-32]) (p≤0,01). Um paciente necessitou de retirada do implante em razão da proeminência sintomática do implante. Conclusão: Esta série de casos sugere que a técnica leva a resultados funcionais satisfatórios, sem falha do implante ou cifose pós-traumática após acompanhamento mínimo de 12 meses de tratamento. Nível de Evidência IV; Série de casos.

RESUMO

Study design: Retrospective review of multicentric data. Objectives: To estimate the time from initial visit to surgery in adolescent idiopathic scoliosis (AIS) patients and the main reasons for the time to surgery in a multicenter study. Methods: This retrospective study evaluated 509 patients with AIS from 16 hospitals across six Latin American countries. From each hospital's deformity registry, the following patient data were extracted: demographics, main curve Cobb angle, Lenke Classification at the initial visit and time of surgery, time from indication-for-surgery to surgery, curve progression, Risser skeletal-maturity score and causes for surgical cancelation or delay. Surgeons were asked if they needed to change the original surgical plan due to curve progression. Data also were collected on each hospital's waiting list numbers and mean delay to AIS surgery. Results: 66.8% of the patients waited over six months and 33.9% over a year. Waiting time was not impacted by the patient's age when surgery first became indicated (p = 0.22) but waiting time did differ between countries (p < 0.001) and hospitals (p < 0.001). Longer time to surgery was significantly associated with increasing magnitude of the Cobb angle through the second year of waiting (p < 0.001). Reported causes for delay were hospital-related (48.4%), economic (47.3%), and logistic (4.2%). Oddly, waiting time for surgery did not correlate with the hospital's reported waiting-list lengths (p = 0.57). Conclusion: Prolonged waits for AIS surgery are common in Latin America, with rare exceptions. At most centers, patients wait over six months, most commonly for economic and hospital-related reasons. Whether this directly impacts surgical outcomes in Latin America still must be studied.
