Effectiveness of Pilates-based exercises on the diastasis recti abdominis in climacteric women: a randomized controlled trial

Introduction: Recent studies have related the climacteric period with changes in connective tissue elasticity that may be related to diastasis recti abdominis. Mat Pilates is a method of exercise without impact that currently has more practitioners, due to its satisfactory results. However, there are no studies that evaluate the effectiveness of mat Pilates for women with diastasis recti abdominis. Objective: To evaluate the effectiveness of the mat Pilates program in climacteric women with diastasis recti abdominis. Methods: This randomized single-blinded clinical trial evaluated climacteric women with diastasis recti abdominis. The participants were randomized into the experimental group, which participated in 3 weekly sessions of mat Pilates for 12 weeks for a total of 36 sessions, and the control group (without exercises). The inter-rectus distance was measured with a digital caliper. The G*Power Version 3.1.9.2. software was used for the sample calculation, and the SPSS 20.0 program was used for statistical analysis. Results: The study comprised 21 women, including 10 in the control group and 11 in the experimental group, with mean ages of 54.3 ± 7.1 and 55.3 ± 6.0 years and body mass index values of 28.8 ± 5.5 kg/m2 and 29.9 ± 4.48 kg/m2, respectively. In the experimental group, reductions were observed in all the measures related to diastasis recti abdominis (p<0.05) in the supraumbilical, umbilical, and infra-umbilical regions. Conclusion: The mat Pilates method is effective for reducing diastasis recti abdominis in the climacteric period.

Effects of community building environment and sports with fitness APP usage on physical exercise habits in teachers in the Yangtze River Delta Region / 中国学校卫生

Objective@#To explore the effects of community building environment and sports with fitness APP usage and their interactions on teachers exercise habits in the Yangtze River Delta Region, so as to provide a scientific basis for the development of a sports and health promotion intervention program for teachers.@*Methods@#A total of 2 530 in service teachers from four provinces and cities in the Yangtze River Delta region, namely, Shanghai, Zhejiang, Jiangsu and Anhui Province, were sampled in May-June 2023 by using convenient cluster random sampling method. Self designed questionnaire was used to collect the basic information of the surveyed teachers, Physical Activity Building Environment Evaluation Questionnaire and the Sports with Fitness APP Usage Questionnaire were used to measure the teachers subjective perception of the community building environment and the usage of sports with fitness APP, respectively. Physical Exercise Habituation Scale was used to assess the level of exercise habits. Logistic regression models were applied to analyze the effects of community building environment and sports with fitness APP usage on physical exercise, and the interaction effects were analyzed by using additive and multiplicative models.@*Results@#Among all the teachers surveyed, 658 of them reported good physical exercise habits (26.0%), and differences in the rate of physical activity habit formation by gender, age, years of teaching, as well as subject of teaching were statistically significant ( χ 2=42.94, 39.73, 35.47, 218.23 , P <0.05). Teachers with physical exercise habits had significantly higher community building environment scores and sports and fitness APP use than teachers without exercise habits ( t =12.17,16.54, P <0.05). Adjusting for the confounders of age, gender, years of teaching experience, and subjects taught, multifactorial unconditional Logistic regression analysis showed that the probability of teachers having good physical exercise habits increased by 22% for every 1-point increase in the community building environment score on average ( OR =1.22, 95% CI =1.11-1.40), and the probability of teachers having good physical exercise habits increased by 16% for every 1-point increase in the sports with fitness APP score on average ( OR = 1.16 , 95% CI =1.03-1.31) ( P <0.05). Interaction analyses showed that there was an additive interaction between the effects of community building environment and sports and fitness APP use on teachers physical exercise habits after adjustment, and the 95% CI for RERI , API and SI were 1.17 -1.65, 0.12-0.46 and 1.78-3.33 ( P <0.05), respectively, and there was no multiplicative interaction ( P >0.05).@*Conclusions@#The community building environment and the usage of sports & fitness APP show impacts in the formation of teachers physical exercise habits in the Yangtze River Delta region, and there is an interaction effect. Enhancing the construction of smart sports centers around the community can provide a high quality external environment for the physical exercise habits formation.

Intervention effects of moderate and high intensities of classroom physical activity on cardiorespiratory fitness and executive function among junior grade one students in Tibetan / 中国学校卫生

Objective@#To explore the intervention effect of different intensity of classroom physical exercise on cardiorespiratory fitness and executive function of Tibetan first grade students at high altitude, so as to provide reference for improving the level of cardiorespiratory fitness and executive function of Tibetan adolescents.@*Methods@#From September to December 2020, 184 Tibetan students from five first grade classes in a middle school in Lhasa, Tibet, were randomly assigned into a control group (81 students in two classes) and an intervention group (103 students in three classes). Both groups followed the same teaching programme, but the intervention group received 36 sessions of moderate to high intensity classroom physical activity, one session per day, Monday,Wednesday and Friday, for 12 weeks. Before and after the intervention, cardiorespiratory fitness and executive function were tested by 20m round trip running and Flanker s experimental paradigm, 2-back s experimental paradigm, and More odd shifting experimental paradigm for inhibitory control, refreshing memory, and switching flexibility, and the results were analysed by analysis of covariance (ANCOVA) to compare the results of the pre and post intervention periods.@*Results@#The maximum oxygen uptake (VO 2max ) of Tibetan first grade students in the intervention group increased by 2.25 mL/(kg〖WW）〗·〖WW(〗min) compared with the control group after the intervention ( t =-3.89, P <0.01); the response time of the inhibitory function was reduced by 4.40 ms, that of the refreshing function by 196.06 ms, and that of the switching function by 92.72 ms in the intervention group compared with the control group ( t =2.98, 4.82 ,3.21, P <0.05).@*Conclusion@#The 12 week moderate to high intensity classroom physical activity intervention has different degrees of improvement effects on cardiorespiratory fitness and executive function in Tibetan adolescents.

Research progress on applications and mechanisms of osteogenesis effect of magnetic fields in oral field / 口腔疾病防治

@#Magnetic fields are safe and used in noninvasive physical therapies. Numerous studies have confirmed that magnetic fields have good osteogenic effects and certain value for clinical application in accelerating orthodontic tooth movement, promoting bone-implant integration, promoting fracture healing and improving the effects of distraction osteogenesis. Magnetic fields are expected to become applied as effective auxiliary methods for treating oral diseases. To support the clinical application of magnetic fields, this article reviews the applications of magnetic fields in the oral cavity, the biological effects on bone cells and the molecular mechanisms through which magnetic fields regulate bone metabolism. The biological effects of magnetic fields on bone cells include promoting osteogenesis by osteoblasts and mesenchymal stem cells and inhibiting bone resorption by osteoclasts. At the molecular level, bone cells sense and respond to magnetic stimulation, and through various mechanisms, such as displacement currents, Lorentz forces, and free radical pair effects, stimuli are transformed into biologically recognizable electrical signals that activate complex downstream signaling pathways, such as the P2 purinergic receptor signaling pathway, adenosine receptor signaling pathway, transforming growth factor-β receptor signaling pathway, mammalian target of rapamycin (mTOR) pathway, and Notch pathway. In addition, magnetic parameters, which are the factors affecting the osteogenic effects of magnetic fields, are discussed. However, the mechanisms of the osteogenic effects of magnetic fields are unclear, and further studies of these mechanisms could provide effective strategies for bone regeneration and periodontal tissue regeneration. In addition, considering the target of magnetic field therapies, combination with other drugs could lead to new strategies for the treatment of oral diseases.

Effect of self efficacy and smoking rationalization tendency in the association of physical activity and smoking cessation beliefs among college students / 中国学校卫生

Objective@#To explore the roles of self efficacy and smoking rationalization tendency in the relationship between college students physical activity and smoking cessation beliefs, in order to provide a basis for the positive effects of college students physical activity on smoking cessation beliefs.@*Methods@#From May 6 to 23 in 2023, 3 048 students from 10 colleges in Jiangxi Province were recruited and surveyed using the Physical Activity Participation Scale, the Smoking Cessation Self efficacy Scale, the Smoking Rationalization Tendency Scale and the Smoking Cessation Belief Scale. The Harman one way test was adopted for common method bias test. Bias correction was unfolded by Bootstrap method, and 95% confidence intervals of parameter estimates were analyzed using repeated sampling 5 000 times.@*Results@#The results of the sequential mediation model analysis showed that physical activity was positively associated with college students beliefs about smoking cessation ( β =0.17), and physical activity, self efficacy and smoking rationalization tendency were positively associated with each other ( β =0.41, 0.08, 0.19) ( P <0.05). Both self efficacy and smoking rationalization tendency positively predicted smoking cessation beliefs ( β =0.19, 0.17, P <0.01). Self efficacy and smoking rationalization tendency mediated the relationship between physical activity and smoking cessation beliefs, with a mediating effect value of 0.09, accounting for 62.82% of the total effect value (0.15).@*Conclusions@#Self efficacy and smoking rationalization tendency have a serial mediating effect between physical activity and smoking cessation beliefs among college students. Interventions should be actively used to enhance college students beliefs about smoking cessation, promote smoking cessation behaviors.

Desempenho no teste FMS® em mulheres e homens praticantes de exercício resistido / FMS® performance of women and men practicing resistance training

Introdução: Os exercícios resistidos (ER) compõem o programa de condicionamento físico de um grande número de indivíduos. Nesses programas são realizadas avaliações periódicas para planejamento e acompanhamento dos efeitos do treinamento. Recentemente, além das avaliações físicas tradicionais tem sido recomendada a inclusão de testes funcionais para avaliação do padrão de movimento dos indivíduos. Objetivo: Avaliar o desempenho funcional de mulheres e homens praticantes de ER. Métodos: Cinquenta e sete participantes (27 mulheres, 26,2 ± 5,1 anos; e 30 homens, 26,3 ± 5,8 anos) fisicamente ativos e experientes na prática de ER foram avaliados através da bateria de testes Functional Movement Screen (FMS®). O escore total foi comparado entre os sexos através do teste U de Mann-Whitney; já a distribuição dos escores parciais (escores de cada teste) e a proporção de escores assimétricos entre os grupos foram realizadas através do teste do Qui-Quadrado (p < 0,05). Resultados: O escore total das mulheres foi 14,6 ± 1,5 pontos, e o dos homens, 15,3 ± 1,4 pontos, de modo que não houve diferença significativa entre os grupos. Considerando os escores parciais, os homens apresentaram melhor desempenho no teste de estabilidade de tronco (p = 0,001) e de agachamento (p = 0,024), enquanto as mulheres apresentaram melhor desempenho no teste de mobilidade de ombros (p = 0,001). Neste último, além de apresentarem piores resultados, os homens foram significativamente mais assimétricos (p = 0,002). Conclusões: Os resultados deste estudo sugerem a necessidade de uma observação mais detalhada dos escores parciais para o planejamento de programas de treinamento personalizados, que atendam às necessidades de cada indivíduo.

Introduction: Resistance training (RT) is part of the physical fitness program of a large number of people. In these programs, periodic evaluations are carried out to plan and monitor the effects of training. Recently, in addition to the traditional physical evaluations, it has been recommended the inclusion of functional tests to evaluate the movement pattern of individuals. Objective: To assess the functional performance of women and men participating of RT. Methods: Fifty-seven participants (27 women, 26.2 ± 5.1 years old; and 30 men, 26.3 ± 5.8 years old), who are physically active and experienced in RT, were assessed through the use of Functional Movement Screen (FMS®). The total score was compared between the genders using the Mann-Whitney U test, and the distribution of the partial scores (scores of individual tests) and the proportion of asymmetric scores between groups was performed through the Chi-Square test (p < 0.05). Results: Women and men presented, respectively, a total score of 14.6 ± 1.5 and 15.3 ± 1.4 points, and there was no significant difference between genders. Considering the partial scores, men performed better in the trunk stability (p = 0.001) and deep squat (p = 0.024) tests, while women presented higher scores in the shoulder mobility test (p = 0.001). In the latter, besides presenting worse results, men were significantly more asymmetrical (p = 0.002). Conclusions: The results of this study suggest the necessity of a more detailed observation of the partial scores in order to plan personalized training programs that consider the participants' individual needs.

Clasificación de los medios y métodos empleados en el entrenamiento funcional de alta intensidad: una reflexión crítica

El entrenamiento funcional de alta intensidad representa un nuevo paradigma del fitness, además es un tipo de ejercicio que crece a nivel mundial en cuanto a practicantes y centros de acondicionamiento físico que lo ofertan; no obstante, la documentación respecto a la forma de realizar este tipo de entrenamientos es escasa, por lo que se puede presentar diferentes problemáticas en este ámbito de la actividad física, el deporte y la salud por desconocimiento de cómo efectuar este tipo de ejercicio físico de alta intensidad. El objetivo estudio de este artículo es hacer una reflexión crítica sobre los medios y métodos aplicados en el entrenamiento funcional de alta intensidad. Posterior a la consulta de literatura se propone la siguiente clasificación para los medios (calisténicos/gimnásticos, cardiometabólico y levantamiento), mientras que los métodos obtuvieron dos clasificaciones, una basada en la modalidad (medios) y otra en la organización (estructura de la sesión). En conclusión, esta nueva propuesta se ajusta más a la realidad del entrenamiento funcional de alta intensidad desde las bases del entrenamiento deportivo.

High-intensity functional training represents a new fitness paradigm, it is also a type of exercise that is growing worldwide in terms of practitioners and fitness centers that offer it, despite the documentation regarding how to perform this type of exercise is scarce, so different problems can arise in this area of physical activity, sports and health due to a lack of knowledge of how to carry out this type of high-intensity physical exercise. The study objective of this article is to make a critical reflection on the means and methods applied in high intensity functional training. After consulting the literature, the following classification is proposed for the means (calisthenics/gymnastics, cardiometabolic and lifting), while the methods obtained two classifications, one based on the modality (means) and the other on the organizational (structure of the session). In conclusion, this new proposal is more in line with the reality of high-intensity functional training from the bases of sports training.

Analgesia por láser de baja potencia en pacientes con tratamiento ortodóncico / Low power laser analgesia in patients with orthodontic treatment i: en

Introducción: El dolor es el síntoma más común luego de la primera activación de la aparatología ortodóncica. El tratamiento analgésico más utilizado es el paracetamol; sin embargo, su uso inhibe la actividad de la ciclooxigenasa y la síntesis de prostaglandinas, lo que puede afectar el mecanismo del movimiento dental y el remodelado óseo. Objetivo: Evaluar la efectividad del láser de baja potencia para el alivio del dolor en pacientes con tratamiento ortodóntico. Métodos: Se realizó un estudio cuasiexperimental de intervención terapéutica, desde enero hasta diciembre de 2020, en 40 pacientes atendidos en la consulta de ortodoncia del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, en quienes se aplicaría fuerza ortodóncica por primera vez. Estos fueron distribuidos de forma aleatoria en 2 grupos de 20 integrantes cada uno: el de estudio, tratado con láser de baja potencia, y el de control, que recibió medicación convencional (paracetamol). Para la validación estadística de la información se emplearon el porcentaje y la prueba de la t de Student para muestras independientes, con 95 % de confiabilidad. Resultados: Luego de tres sesiones terapéuticas, 90,0 % del grupo de estudio refirió no presentar dolor o sentirlo de forma leve, mientras que del grupo de control solo 10,0 % de los pacientes fue ubicado en cualquiera de las dos categorías anteriores. Existió diferencia significativa entre ambos grupos (p=0,00). Conclusiones: Se demostró que el láser, como terapia alternativa, fue más efectivo que el paracetamol.

Introduction: Pain is the most common symptom after the first activation of orthodontic appliance. The most widely used analgesic treatment is paracetamol; however, its use inhibits cyclooxygenase activity and prostaglandin synthesis, which can affect the mechanism of tooth movement and bone remodeling. Objective: To evaluate the effectiveness of low power laser for pain relief in patients with orthodontic treatment. Methods: A quasi-experimental study of therapeutic intervention was carried out, from January to December 2020, in 40 patients treated at the orthodontic clinic of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, in whom orthodontic force was applied for the first time. These were randomly distributed into 2 groups of 20 members each: the study group, treated with low-power laser, and the control group, that received conventional medication (paracetamol). For statistical validation of data, the percentage and the Student's t test for independent samples were used, with 95 % confidence interval. Results: After three therapeutic sessions, 90.0% of the study group reported not presenting pain or feeling it slightly, while only 10.0% of patients in control group were put in any of the two previous categories. There was a significant difference between both groups (p=0.00). Conclusions: Laser, as an alternative therapy, was shown to be more effective than paracetamol.

Calcitonin as a Pharmacological Anchorage in Orthodontics

Objective: This study aimed to evaluate the effects of salmon calcitonin administration as a pharmacological anchoring agent in orthodontics and to determine the influence of locally applied calcitonin on serum calcium levels. The secondary aim was to observe the response of dental and periodontal tissues using light microscopy. Methods: Fourteen healthy male adult Wistar rats with an average weight of 250 g had their teeth moved, seven of which received a local injection of salmon calcitonin in the furcation region of the left upper first molar. Concurrently, the remaining seven were used as controls. In the control group, saline solution was injected in the bifurcation region of tooth 26 to subject these animals to the same stress level as those of the experimental group. After 14 days, a 6 mm diameter orthodontic elastic band was inserted between teeth 26 and 27 in all animals to induce the movement of these teeth. The rats were anaesthetised and exsanguinated on day 21. In both groups, tooth movement and serum calcium levels were measured. The jaws were dissected with straight scissors, and tissue blocks containing gingiva, bone and teeth were identified, fixed and demineralised. Then, the pieces were cut into semi?serial slices, stained with hematoxylin, eosin, and Mallory’s trichrome, and analysed under an Axiophot light microscope. Results: There was significantly less tooth movement in the experimental group ( ±X DP ; 0,150 mm ± 0,037) than in the control group (0,236 mm ± 0,044; P = 0,003), while there was no significant difference in serum calcium levels between the two groups (control ±X DP ; 9,53 mg/dl ± 1,53; experimental 10,81 mg/dl ± 1,47; P = 0,15). Conclusion: While calcitonin did not completely inhibit osteoclast activity, it promoted orthodontic anchorage, apparently, by local action.

A resistência do fluxo inspiratório modifica a intensidade de uma sessão de pilates? / Does inspiratory flow resistance modify the intensity of a pilates session?

INTRODUÇÃO: As evidências sobre a melhora da capacidade funcional utilizando o Método Pilates não são contundentes. Uma possibilidade de melhorar o efeito de uma sessão de Pilates sobre a capacidade cardiorrespiratória de seus praticantes é utilizar a resistência de fluxo inspiratório (RFI) de forma concomitante. Esse efeito pode ser visualizado através da determinação do limiar glicêmico (LG), técnica utilizada como marcador de intensidade do exercício. OBJETIVO: Testar a hipótese de que a utilização de RFI em uma sessão de pilates antecipa o LG. MÉTODOS: Estudo crossover de corte transversal. Foram avaliados 26 indivíduos de ambos os sexos, sendo 10 do sexo masculino, sadios e com idade entre 20 e 40 anos. Os voluntários foram randomizados para dois protocolos: Protocolo RFI ­ 11 movimentos do Método Pilates com RFI utilizando 20% da pressão inspiratória máxima; e Protocolo sem RFI (SRFI) ­ 11 movimentos do Método Pilates sem RFI. Os dois protocolos foram realizados no mesmo dia, sendo um pela manhã e outro à tarde, conforme randomização feita por sorteio aleatório simples. No repouso e ao final de cada movimento coletas de sangue capilar foram realizadas para dosagem da glicemia e construção da curva glicêmica. O LG foi determinado no menor ponto da curva. RESULTADOS: O LG foi antecipado no protocolo que utilizou RFI, ou seja, no protocolo com RFI o LG foi visualizado no sexto exercício, enquanto no protocolo SRFI o LG foi visualizado no nono exercício (p<0,05). CONCLUSÃO: A RFI antecipou o LG, o que sugere que a RFI aumenta a intensidade de uma sessão de pilates. Isso aventa a hipótese de que a RFI pode proporcionar a médio e longo prazo benefícios adicionais aos praticantes do Método Pilates.

INTRODUCTION: The evidence on the improvement of functional capacity using the Pilates Method is not conclusive. One possibility to improve the effect of a Pilates session on the cardiorespiratory capacity of its practitioners is to use the inspiratory flow resistance (IFR) concomitantly. This effect can be visualized by determining the glycemic threshold (GT), a technique used as an exercise intensity marker. OBJECTIVE: To test the hypothesis that the use of IFR in a Pilates session anticipates GT. METHODS: Cross-sectional crossover study. A total of 26 individuals of both genders were evaluated, 10 of whom were male, healthy, and aged between 20 and 40 years. The volunteers were randomized to two protocols: Protocol IFR - Eleven movements of the Pilates method with IFR using 20% of the maximum inspiratory pressure, and Protocol no IFR (NIFR) - Eleven movements of the Pilates method without IFR. The two protocols were performed on the same day, one in the morning and the other in the afternoon, according to randomization by simple random draw. At rest and at the end of each movement, capillary blood collections were performed to measure blood glucose and construct the glycemic curve. GT was determined at the smallest point on the curve. RESULTS: The GT was anticipated in the protocol that used IFR; that is, in the protocol with IFR, the GT was visualized in the sixth exercise, while in the NIFR protocol, the GT was visualized in the ninth exercise (p<0.05). CONCLUSION: IFR anticipated GT, which suggests that IFR increases the intensity of a Pilates session. This suggests the hypothesis that IFR can provide additional medium and long-term benefits to Pilates method practitioners.

Resumo Objetivo Avaliar o efeito da Educação em Neurociência da Dor aliada ao Pilates na catastrofização da dor em idosos com lombalgia crônica inespecífica. Métodos Ensaio clínico controlado randomizado com 80 participantes divididos em dois grupos: Grupo Pilates combinado com Educação em Neurociência da Dor - GPE, e Grupo Pilates- GP. As medidas foram feitas no início, pós-intervenção e após seis meses (seguimento). O protocolo incluiu três sessões individuais de Educação em Neurociência da Dor (END) de 30 min (somente para o GPE) e, posteriormente, oito semanas de Pilates (duas vezes por semana, 50 min/sessão, para ambos os grupos). Resultados Comparações das diferenças pré-pós e de seguimento em catastrofização, cinesiofobia, incapacidade e intensidade da dor não mostraram evidências de que a END teve efeitos adicionais em comparação com os exercícios isoladamente. Uma vantagem provável do presente protocolo de END foi que as taxas de abandono para o GPE foram menores do que para o GP, mostrando que a END aumentou a adesão ao exercício. Conclusão A relevância clínica do estudo é que o Pilates é uma intervenção segura para idosos com dor lombar crônica inespecífica e a END pode aumentar a adesão ao exercício nessa população.

Abstract Objective Verify the effect of Pain Neuroscience Education combined with Pilates on catastrophizing in older people with chronic non-specific low back pain. Methods A randomized controlled clinical trial with 80 participants divided into two groups: Pilates combined with Pain Neuroscience Education Group - PEG, and Pilates Group - PG. The measurements were taken at baseline, post-intervention, and after 6 months (follow-up). The protocol included three individual 30-min PNE sessions (only for PEG) and, after that, 8 weeks of Pilates (twice a week, 50 min/session, for both groups). Results Comparisons of pre-post and follow-up differences in catastrophizing, kinesiophobia, disability, and pain intensity showed no evidence that PNE had any additional effects when compared with exercises alone. One likely advantage of the present PNE protocol was that the dropout rates for the PEG group were lower than for the PG group, showing that PNE has increased exercise adherence. Conclusion The clinical relevance of the study is that Pilates is a safe intervention for older people with non-specific chronic low back pain, and that PNE can increase adherence to exercise for this population.

The Effects of Orthodontic Tooth Movement on Clinical Attachment Level Changes in Treated Periodontitis Adult Patients with Malocclusion: A Systematic Review and Meta-analysis

ABSTRACT Objective: To investigate the effects of orthodontic tooth movement on clinical attachment level (CAL) changes in treated periodontitis in adult patients with malocclusion. Material and Methods: Present study is based on PRISMA guidelines; all articles published in international databases such as PubMed, Scopus, Science Direct, and Embase between 2012 to May 2022 are included. 95% confidence interval (CI) for mean difference with fixed effect modal and inverse-variance were calculated. Data analysis was performed using STATA.V16 software. Results: In the initial review, duplicate studies were eliminated, abstracts of 175 studies were reviewed, two authors reviewed the full text of 21 studies, and finally, eleven studies were selected. The mean of CAL gain was 2.29 mm (MD, 95% CI -2.47 mm, -2.12 mm; p=0.00) (I2=91.81%; p=0.00; high heterogeneity). The mean difference of PPD changes was -1.93 mm (MD, 95% CI -2.07 mm, -1.80 mm; p=0.00) (I2=98.52%; p=0.00; high heterogeneity). Conclusion: Due to the limitations of the study and based on the meta-analysis, it is observed that orthodontic treatment is performed with higher success after reconstructive surgery with periodontal improvement.

Influence of risedronate on orthodontic tooth movement in rodents: a systematic review and case report

ABSTRACT Introduction: Bisphosphonates have an inhibitory impact on osteoclastic activity, reducing bone resorption. However, the influence of risedronate on tooth movement is not well-defined. Objective: This systematic review assessed the effect of risedronate intake on orthodontic tooth movement. A case report was also provided. Methods: Two independent reviewers searched six databases (PubMed, Web of Science, Ovid, Lilacs, Scopus, and Open Grey). The searches were carried out in April/2020, and an update was set in place in June/2023. Therefore, the searches considered a timeline from the databases' inception date until June/2023, with no publication date and/or language restrictions. The clinical question focused on evaluating the orthodontic tooth movement and relapse movement (Outcome) in animals (Population) exposed to risedronate (Exposure), compared to control groups (Comparison). The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines were applied, and the protocol was registered in PROSPERO (CRD42020168581). The risk of bias was determined using the Systematic Review Centre for Laboratory Animal Experimentation protocol (SYRCLE). Results: Two studies in rats and one in guinea pigs were included in the systematic review. The studies reported a decrease in orthodontic tooth movement, a reduction in the relapse movement, and a reduced number of positive tartrate-resistant acid phosphatase (TRAP) cells, with a significantly reduced number of bone gaps after the administration of risedronate in rats. A case report illustrated the effects of risedronate administration in one patient. Conclusion: Based on the systematic review, risedronate seems to impair orthodontic tooth movement and relapse due to a decrease in bone resorption cells.

Um relato de caso também é apresentado. Métodos: Dois revisores independentes pesquisaram seis bases de dados (PubMed, Web of Science, Ovid, Lilacs, Scopus e Open Grey), considerando o período de abril de 2020 até junho de 2023, sem restrições de data e/ou idioma de publicação. A questão clínica focou em avaliar o movimento ortodôntico dos dentes e movimento de recidiva (resultado) em animais (população) expostos ao risedronato (exposição) em comparação com grupos de controle (comparação). Foram aplicadas as Diretrizes Preferenciais para Revisão Sistemática e Metanálise (PRISMA) e um protocolo foi registrado no PROSPERO (CRD42020168581). O risco de viés foi determinado utilizando o protocolo do Centro de Revisão Sistemática para Experimentação em Animais de Laboratório (SYRCLE). Resultados: Dois estudos em ratos e um em porquinhos-da-índia foram incluídos na revisão sistemática. Os estudos relataram uma diminuição no movimento ortodôntico dos dentes, uma redução no movimento de recidiva e um número reduzido de células positivas à fosfatase ácida tartarato-resistente (TRAP) com um número significativamente reduzido de falhas ósseas após a administração de risedronato em ratos. Um relato de caso ilustrou os efeitos da administração de risedronato em uma paciente. Conclusão: Com base na revisão sistemática, o risedronato parece interferir no movimento ortodôntico dos dentes e na recidiva devido a uma diminuição nas células de reabsorção óssea.

Deflection of tandem archwire in a specific self-ligating metal bracket system: an in vitro study

Abstract The aim of this study was to quantify the force exerted by tandem archwires in a specific system of passive self-ligating bracket. Forty-eight thermo-activated nickel-titanium orthodontic archwires were separated into four groups (n = 12): G1 - two .014" + .014" round archwires; G2 - two .014" + .016" round archwires; G3 - .014" x .025" rectangular archwire; and. G4 - .016" x .022" rectangular archwire. Brackets were fixed onto teeth 1.5 to 2.5 using a device that represented the upper teeth, maintaining an interbracket distance of 6.0 mm. The deflection tests were performed using the structure representative of tooth 1.1 as support on the Instron testing machine at a speed of 2.0 mm/min. The archwires were evaluated at deflections of 0.5 mm, 1.0 mm, and 1.5 mm. The data were analyzed by a generalized linear model, considering values at different deflections as repeated measurements in the same experimental unit (α = 0.5%). At 0.5 mm, higher forces were observed in G2 and G3, which did not differ significantly (p > 0.05). The lowest force was observed in G4 (p < 0.05). At 1.0 mm and 1.5 mm, the highest force was observed in G3, followed by G4 and G2 (p < 0.05). The lowest force was observed in G1 (p < 0.05). In general, tandem archwires (same or different calibers) in a specific passive self-ligating bracket exerted lower force when compared with rectangular archwires.

Effect of the association of continuous shortwave diathermy and Pilates-based exercises on pain, depression, and anxiety in chronic non-specific low back pain: a randomized clinical trial

Chronic nonspecific low back pain (CNLBP) is the most common musculoskeletal condition, which can be influenced by nociceptive, psychosocial, cognitive, and affective aspects, causing vulnerabilities and impairing the individual's ability to manage pain. The association of continuous shortwave diathermy (CSWD) with Pilates-based exercises may contribute to reduce pain, depression, and anxiety in patients with CNLBP. A single-blind randomized clinical trial was performed in which 36 patients with CNLBP were divided into a control group that received placebo CSWD and an intervention group that received active CSWD. Both groups received 12 sessions of Pilates-based exercises. Pain, depression, and anxiety variables were evaluated using the McGill questionnaire, the Beck Depression Inventory, and the Visual Analog Anxiety Scale. Assessments were performed at baseline, after three and six weeks of treatment, and at the three-month follow-up. The Shapiro-Wilk test, Student's t-test, Mann-Whitney U test, chi-squared test, and repeated measures ANOVA, with α=0.05, were used to compare the outcomes, and indicated that active CSWD did not present additional improvement in the assessed variables in CNLBP patients compared to the placebo group. Both groups improved pain and depression at follow-up and reduced anxiety only during Pilates-based exercises. Therefore, only Pilates-based exercises seemed sufficient to manage patients with CNLBP.

Cross lagged analysis of adolescent social adaptability, physical exercise and mental health / 中国学校卫生

Objective@#To explore the relationships among social adaptation, physical exercise, and mental health of adolescents, so as to provide theoretical basis for social adaptation and mental health improvement.@*Methods@#Longitudinal follow up survey data were collected from 1 163 adolescents in Jinan City, Shandong Province in September 2021 (T1), January 2022 (T2), and June 2022 (T3) by cluster random sampling method. The relationship between social adaptability, physical exercise, and mental health of adolescents was analyzed through cross lagged analysis.@*Results@#There were significant sex differences in physical exercise and mental health among adolescents on T1, T2, and T3 ( Z =-3.83, -3.43, -4.59; -12.45, -8.93, -8.72, P <0.01), with male students had more physical exercise [35(28,42),36(33,42),38(35,43)] and better mental health [12(12,17),17(17,21),14(14,26)] levels than female students [33(27,40),35(31,40),36(33,41); 9(9,12),12(12,23),12(12,23)]. No similar sex difference in social adaptability (T1, T2, T3) [male: 22 (14, 24), 22 (14, 24), 22 (16, 24); female: 21 (11, 23), 20 (14, 24), 22 (17, 24)] ( Z =-0.79, -1.19, -1.34, P >0.05). Temporal and synchronous correlations were found in social adaptability, physical exercise and mental health ( r =0.18-0.67，0.12-0.68, P <0.01). Teenager physical exercise and mental health could predict social adaptability across time ( β T1-T2 =0.25,0.13; β T2-T3 =0.25,0.06, P <0.05), with a mediating effect on the impact path of physical exercise on social adaptability in psychological health ( β =0.14, P <0.05).@*Conclusions@#There is a causal relationship between physical exercise, mental health, and social adaptability among adolescents. Encouraging adolescents to actively participate in physical exercise and promoting mental health can effectively enhance their social adaptability.
