RESUMO
ABSTRACT Objective: To compare effectiveness of Dynesys and hybrid system in treating patients with multi-segmental lumbar degenerative disease (LDD). Methods: Patients involved in this retrospective study were divided into Dynesys (n = 22) and Hybrid (n = 13) groups. Clinical outcomes were evaluated using Oswestry Disability Index (ODI), and Visual Analogue Scale (VAS). Radiologic evaluations included X-ray, MRI, and CT. Furthermore, different complications were analyzed. Results: At the last follow-up, ODI and VAS of each group were improved (p < 0.05), and the range of motion (ROM) of operating segments decreased. However, Dynesys group preserved a larger extent of ROM at the final follow-up (p < 0.05). ROM of the upper adjacent segment was increased in both groups (p < 0.05), while the disc heights were decreased at the final follow-up (p < 0.05). Besides, Dynesys group had a more obvious decrease in the disc height of dynamic segments (p < 0.05). No significant difference existed in complications between both groups (p > 0. 05). Conclusion: In our study, similar satisfactory results were obtained in both groups. Both surgical procedures can be employed as effective treatments for middle-aged and physically active patients with multi-segmental LDD. Level of Evidence III; Retrospective Comparative Study.
RESUMO Objetivo: Comparar a eficácia do Dynesys e do sistema híbrido no tratamento de pacientes com doença degenerativa lombar multissegmentar (DLD). Métodos: Os pacientes envolvidos neste estudo retrospectivo foram divididos em grupos Dynesys (n = 22) e Híbrido (n = 13). Os desfechos clínicos foram avaliados por meio do Oswestry Disability Index (ODI) e da Escala Visual Analógica (EVA). As avaliações radiológicas incluíram radiografia, ressonância nuclear magnética (RNM) e tomografia computadorizada. Ademais, diferentes complicações foram analisadas. Resultados: No acompanhamento final, o ODI e a EVA de todos os grupos melhoraram (p < 0,05), e houve diminuição da amplitude de movimento (ADM) dos segmentos operacionais. No entanto, o grupo Dynesys preservou uma maior extensão da ADM no acompanhamento final (p < 0,05). A ADM do segmento superior adjacente foi ampliada em ambos os grupos (p < 0,05), enquanto as alturas dos discos foram reduzidas no acompanhamento final (p < 0,05). No entanto, o grupo Dynesys apresentou uma redução mais evidente na altura do disco dos segmentos dinâmicos (p < 0,05). Não houve diferença significativa nas complicações entre esses dois grupos (p > 0,05). Conclusão: Neste estudo, resultados satisfatórios semelhantes foram obtidos em ambos os grupos. Ambos os procedimentos cirúrgicos podem ser empregados como tratamentos eficazes para pacientes de meia-idade e fisicamente ativos com LDD multissegmentar. Nível de Evidência III; Estudo Retrospectivo Comparativo.
RESUMO
Objective@#This study aims to investigate the sub-health status of vocational college students in Changchun City.@*Methods@#In this study, 1 282 students from 7 vocational colleges were investigated from June 2018 to December 2018 in Changchun. The questionnaire survey collected information on demographic and lifestyle, as well as sub-health status. Demographic and lifestyle characteristics were analyzed by univariate analysis and were explored associations with sub-health status through binary logistic stepwise regression analysis.@*Results@#A total of 195 cases (15.21%) of physical and psychological sub-health were detected. And fifty-seven male students (13.65%) reported physical and psychological sub-health, which was significantly lower than that of female(16.18%)(χ2=8.00, P=0.01). Those who spent more time online, being irregular eating pattern, smokers and drinkers were more likely to report sub-health(P<0.05). Those who exercised frequently and paid more attention to health were less likely to report sub-health(P<0.05). Multivariate analyses showed that the risk of physical and psychological sub-health status increased among irregular diet, smokers and drinkers(OR=1.41, 1.68, 2.03, P<0.05). Frequent exercise and high attention paid to health was associated with lower risk of physical and psychological sub-health(OR=0.24, 0.55, P<0.05).@*Conclusion@#Sub-health status among vocational college students in Changchun is related to irregular diet, smoking, drinking, infrequent exercise and low attention to health. These results suggest health awareness, health education, as well as healthy lifestyle should be strengthened to improve sub-health status of vocational college students.
RESUMO
Objetivo. Identificar las ventajas posoperatorias de la amigdalectomía en conjunto con la faringoplastia en comparación con la amigdalectomía sola en niños con apnea obstructiva del sueño. Métodos. En un estudio prospectivo observacional, los pacientes que cumplían con los criterios del estudio fueron asignados aleatoriamente a dos grupos: el grupo de amigdalectomía y faringoplastia, y el grupo de solo amigdalectomía. En ambos grupos, también se practicó adenoidectomía a los pacientes con vegetaciones. Se compararon los procesos de cicatrización en la herida faríngea y las proporciones hemorrágicas. Además, se evaluó la función velofaríngea posoperatoria. Resultados. La faringoplastia junto con la amigdalectomía se practicó en 328 niños con apnea obstructiva del sueño debido a hipertrofia amigdalina, y la amigdalectomía sola, en 275 niños. Estas cohortes no mostraban diferencias demográficas significativas. Por otro lado, se encontró que la pérdida de sangre fue significativamente menor en el grupo que recibió amigdalectomía y faringoplastia (p < 0,01), y el proceso de cicatrización fue notablemente más breve. La función velofaríngea posoperatoria no resultó afectada. Conclusiones. En comparación con la amigdalectomía, la amigdalectomía junto con la faringoplastia redujeron la duración del proceso de cicatrización y la pérdida de sangre; no obstante, las complicaciones posoperatorias no aumentaron. En nuestra opinión, la combinación de faringoplastia y amigdalectomía reúne un gran potencial en el tratamiento de los niños con apnea obstructiva del sueño.
Purpose. The study aims to identify the postoperative advantages of tonsillectomy in conjunction with pharyngoplasty and tonsillectomy alone in children with obstructive sleep apneas. Methods. In a prospective observational study, patients who met the study criteria were randomly divided into two groups: tonsillectomy and pharyngoplasty group, and tonsillectomy alone group. In both groups, adenoidectomy was also performed in patients with adenoid hypertrophy. Differences in their healing processes in the pharyngeal wound and their hemorrhage proportions were compared. Furthermore, postoperative velopharyngeal function was also assessed. Results. Pharyngoplasty together with tonsillectomy was performed in 328 children with obstructive sleep apnea from tonsillar hypertrophy, and tonsillectomy was performed in 275 children. These cohorts did not reveal any significant demographic differences between groups. Furthermore, blood loss was found to be significantly decreased in the tonsillectomy and pharyngoplasty group (P <0.01), and the healing process was markedly shorter. Postoperative velopharyngeal function was not affected. Conclusions. Tonsillectomy in conjunction with pharyngoplasty reduced the duration of the healing process and blood loss, compared with tonsillectomy alone; however, postoperative complications did not increase. We consider pharyngoplasty in conjunction with tonsillectomy has great potential in the treatment of children with obstructive sleep apnea.
