The effect of music on menopausal symptoms, sleep quality,and depression: a randomized controlled trial

SUMMARY OBJECTIVE: This study aimed to determine the effect of music on menopausal symptoms, sleep quality, and depression levels in menopausal women. METHODS: This randomized controlled study was carried out between August and December 2022. The study sample consisted of 61 menopausal women (intervention: 30 and control: 31). The intervention group listened to music twice a day for 5 weeks, with a total of 70 sessions. The control group received only routine care. Menopause symptoms, depression levels, and sleep quality were evaluated at the beginning and the end of the study using the Menopausal Symptoms Rating Scale, Beck Depression Inventory, and Pittsburg Sleep Quality Index. RESULTS: The post-test Menopausal Symptoms Rating Scale, Beck Depression Inventory, and Pittsburg Sleep Quality Index scores of the menopausal women were found to be lower in the intervention group than in the control group (p=0.011, p=0.001, and p=0.006, respectively). When the pre-test and post-test mean scores were compared, the mean menopausal symptoms and depression levels decreased, and sleep quality increased significantly in the intervention group. No significant difference was observed in the control group. CONCLUSION: This study shows that music may have an effect on reducing the level of menopausal symptoms and depression levels and also increasing the sleep quality of menopausal women.

Factors and Their Impact on Treatment Effect of Acupuncture in Different Outcomes: A Meta-Regression of Acupuncture Randomized Controlled Trials / 中国结合医学杂志

BACKGROUND@#The effects of acupuncture have varied in different randomized controlled trials (RCTs), and there are many factors that influence treatment effect of acupuncture in different outcomes, with conflicting results.@*OBJECTIVE@#To identify factors and their impact on the treatment effect of acupuncture in different outcomes.@*METHODS@#Acupuncture RCTs were searched from 7 databases including Medline (PubMed), Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine disc between January 1st, 2015 and December 31st, 2019. Eligible studies must compare acupuncture to no acupuncture, sham acupuncture, or waiting lists, and report at least 1 patient-important outcome. A multi-level meta-regression was conducted using a 3-level robust mixed model and univariate analyses were performed for all independent variables, even those excluded from the multivariable model due to collinearities. We used thresholds of 0.2 and 0.4 for the difference of standardized mean differences (SMDs), categorising them as small (<0.2), moderate (0.2-0.4), or large (>0.4) effects.@*RESULTS@#The pain construct analysis involved 211 effect estimates from 153 studies and 14 independent variables. High-frequency acupuncture treatment sessions produced larger effects compared to low-frequency sessions [large magnitude, the difference of adjusted SMDs 0.46, 95% confidence interval (CI) 0.07 to 0.84; P=0.02]. The non-pain symptoms construct analysis comprised 323 effect estimates from 231 studies and 15 independent variables. Penetrating acupuncture showed moderately larger effects when compared to non-penetrating acupuncture (0.30, 95% CI 0.06 to 0.53; P=0.01). The function construct analysis included 495 effect estimates from 274 studies and 14 independent variables. Penetrating acupuncture and the flexible acupuncture regimen showed moderately larger effects, compared to non-penetrating acupuncture and fixed regimen, respectively (0.40, 95% CI 0 to 0.80; P=0.05; 0.29, 95% CI 0.06 to 0.53; P=0.01).@*CONCLUSIONS@#High-frequency acupuncture sessions appear to be a more effective approach to managing painful symptoms. Penetrating acupuncture demonstrated greater effect in relieving non-painful symptoms. Both penetrating acupuncture type and flexible acupuncture regimen were linked to significant treatment effects in function outcomes. Future studies should consider the factors that are significantly associated with the effects of acupuncture in patient-important outcomes.

Effect of Acupuncture on Endometrial Blood Flow in Women Undergoing in vitro Fertilization Embryo Transfer: A Single Blind, Randomized Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To evaluate the effect of manual acupuncture on endometrial blood flow parameters by three-dimensional (3D) power Doppler ultrasound in women undergoing in vitro fertilization embryo transfer (IVF-ET).@*METHODS@#Seventy patients undergoing IVF-ET were equally randomized into traditional or sham acupuncture treatment group for totally 4 days (from the day of oocyte aspiration to the day of embryo transfer) of treatment by random envelope method at the Reproductive Medicine Center and Outpatient Department of Integrated Traditional Chinese and Western Medicine, Tongji Hospital, Tongji Medicine College, Huazhong University of Science and Technology from January 2013 to December 2015. Patients in the traditional acupuncture group accepted traditional acupuncture methods with manual acupuncture, and Zhongji (CV3), Qihai (CV 6), Sanyinjiao (SP6), Taichong (LR 3), Tianshu (ST 25), Guilai (ST 29) and Zusanli (ST 36) were chosen. Patients at the sham acupuncture group accepted shallow acupuncture methods at 4 non-meridian points at each shoulder and upper arm. Outcome measures included endometrial ultrasonic indices such as vascularization index (VI), flow index (FI) and vascularization flow index (VFI), endometrial thickness and volume, subendometrial VI (sVI), subendometrial FI (sFI), subendometrial VFI (sVFI), implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births.@*RESULTS@#Finally, 34 patients in the traditional acupuncture group and 35 in the sham acupuncture group completed this trial. VI, FI and VFI of the traditional acupuncture group were significantly higher than those in the sham acupuncture group (P<0.05). No significant differences were found in endometrial thickness, endometrial volume, sVI, sFI, sVFI, implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births (P>0.05).@*CONCLUSIONS@#Manual acupuncture performed after oocyte aspiration and before transplantation improved the endometrial blood flow parameters VI, RI and VFI in women who underwent IVF-ET, instead of sVI, sFI and sVFI. Therefore, acupuncture might be beneficial in women undergoing IVF-ET by increasing endometrial blood flow and endometrial receptivity. (Registration No. ChiCTR2100053354).

Effect of the staging comprehensive treatment with acupuncture-moxibustion on Bell's facial palsy in the acute stage / 中国针灸

OBJECTIVES@#To compare the clinical effect on Bell's facial palsy in the acute stage between the staging comprehensive treatment with acupuncture-moxibustion and western medication.@*METHODS@#Sixty patients with Bell's facial palsy in the acute stage were randomly divided into an observation group and a control group, with 30 cases in each one. The patients in the control group were administered orally with prednisone acetate tablets and methylcobalamin tablets until the 28th day of illness. In the observation group, the staging comprehensive treatment with acupuncture-moxibustion was adopted. On the affected side, Qianzheng (EX-HN 16), Yifeng (TE 17), Sibai (ST 2), Yangbai (GB 14), Jiache (ST 6), Dicang (ST 4) and Touwei (ST 8), etc. were stimulated. In the acute stage (Day 1 to 7 of illness), the routine acupuncture and the point-toward-point needle insertion were delivered, no any manipulation was exerted at acupoints, and the needles were retained for 30 min. In the subacute stage (Day 8 to 14 of illness), on the base of the treatment as the acute stage, the depth of needle insertion was adjusted at a part of acupoints and the even needling technique was operated by twisting needle. Besides, electroacupuncture (EA) was attached to Qianzheng (EX-HN 16) and Dicang (ST 4), with continuous wave of low intensity and high frequency, 100 Hz, for 20 min. In the recovery stage (Day 15 to 28 of illness), on the base of the treatment as the subacute stage, the heavy stimulation of acupuncture was given, in which, the sticking and lifting needle techniques were delivered after the needles were inserted from Sibai (ST 2) toward Dicang (ST 4), and from Dicang (ST 4) toward Jiache (ST 6), separately; warm needling was operated at Yifeng (TE 17), and EA changed to stimulate the acupoints with the intermittent wave of high intensity and low frequency, 2 Hz, for 30 min. Acupuncture-moxibustion was given once every other day until the end of the 28th day of illness. The level of House-Brackmann facial nerve function rating scale (H-B grade),the score of Sunnybrook facial nerve grading system (Sunnybrook), the score of facial disability index (FDI), the temperature difference in the infrared thermal imaging facial area and electromyogram (EMG) situation of the affected muscle group were observed before and after treatment in the two groups. Using musculoskeletal ultrasound,the facial nerve diameter was detected and the clinical effect was compared between the two groups.@*RESULTS@#After treatment, the level of H-B grade, Sunnybrook score, the scores of physical function and social life function in FDI were improved when compared with those before treatment in the patients of either group (P<0.01, P<0.05), and the results of these evaluations in the observation group were better than those of the control group (P<0.05). After treatment, the temperature difference of the frontal area, the eye area, the zygomatic area and the mouth corner was declined in comparison with that before treatment in the two groups (P<0.05), and the temperature difference in each area in the observation group was lower than that of the control group (P<0.05).The root mean square (RMS) of the frontal muscle group, the zygomatic muscle group and the orbicularis muscle group on the affected side increased in comparison with that before treatment in the two groups (P<0.01), and RMS of the observation group was higher than that of the control group (P<0.05) after treatment. Before treatment, the diameter of the facial nerve on the affected side was larger than that on the healthy side (P<0.01), and after treatment, the diameter on the affected side was reduced when compared with that before treatment in the two groups (P<0.01); the diameter of the facial nerve on the affected side in the observation group was smaller than that of the control group (P<0.05), while, the diameter on the affected side was larger when compared with the healthy side in the control group (P<0.05). The total effective rate of the observation group was 93.3% (28/30), higher than that of the control group (83.3% [25/30], P<0.05).@*CONCLUSIONS@#The staging comprehensive treatment with acupuncture-moxibustion is clearly effective on Bell's facial palsy in the acute stage, which affirms the effectiveness of acupuncture-moxibustion for the acute stage of Bell's facial palsy in comparison with conventional western medication.

Ultrasonic Bone Scalpel versus Conventional Technique for Thoracolumbar Spinal Decompression: A Prospective Randomized Controlled Trial / Bisturi ósseo ultrassônico versus técnica convencional para descompressão espinhal torácica: Um teste controlado randomizado prospectivo

Abstract Objective The purpose of the present study is to compare intraoperative blood loss, operating time, laminectomy time, hospital length of stay, and complications in thoracolumbar spinal decompression using ultrasonic bone scalpels (UBSs) with conventional procedures. Methods Forty-two patients who underwent decompressive laminectomy and pedicular screw fusion with a surgical level of 1-5 levels between February 1, 2020, and June 30, 2022, in a single institution were evaluated for eligibility, and 11 were excluded due to a history of spinal surgery (n= 3), spinal tumor (n= 3), and spinal infection (n= 5). A total of 31 patients were randomly divided into the UBS group (n =15) and the conventional group (n =16). Intraoperative blood loss, operating time, laminectomy time, hospital length of stay, and complications were recorded. Results Intraoperative blood loss and laminectomy time were significantly lower in the UBS group (656.0 ± 167.6 ml, 54.5 ± 27.4 minutes, respectively) than in the conventional group (936.9 ± 413.2 ml, 73.4 ± 28.1 minutes, respectively). Overall operation time, hospital length of stay, and complications were all similar between the groups. Conclusion The UBS is a useful instrument for procedures performed near the dura mater or other neural tissue without excessive heat or mechanical injury. This device is recommended for various spinal surgeries in addition to high-speed burrs and Kerrison rongeurs.

Efectividad de la Rehabilitación basada en Ejercicio Físico sobre la Sintomatología Prolongada de COVID-19 en Personas Mayores: Una Revisión Sistemática / Effectiveness of Rehabilitation based on Physical Exercise on Prolonged Symptoms of COVID-19 in Older People: A Systematic Review

Propósito. Sistematizar la evidencia respecto a la efectividad de los programas de rehabilitación, basados en la prescripción del ejercicio físico, aplicados en personas mayores con síntomas prolongados de COVID-19. Métodos. Se revisaron las bases de datos PubMed, Science Direct, SPORTDiscus, MEDLINE Complete y Web of Science. Se buscaron estudios de tipo ensayo controlado aleatorizado con fecha de publicación desde el año 2020 hasta octubre de 2022 centrados en programas de rehabilitación, o intervención terapéutica, basados en ejercicio físico en individuos mayores o igual de 60 años que manifiesten síntomas persistentes de COVID-19 posterior a la fase aguda. Resultados. Dos ensayos controlados aleatorizados, que midieron la eficacia de la rehabilitación con ejercicio físico en personas de edad avanzada (mayores o iguales a 60 años), fueron identificados. Los resultados mostraron mejoría de la tolerancia al esfuerzo, la función respiratoria y el bienestar psicológico en los adultos mayores con síntomas post-COVID-19. Sin embargo, la cantidad de estudios es baja y la representación de este grupo etario, también. Conclusión. Los programas de rehabilitación, en personas mayores, basados en ejercicio, son efectivos para tratar los síntomas post-COVID-19. Se necesitan más estudios comparativos de alta calidad, en personas mayores, para desarrollar programas de rehabilitación que permitan afrontar la fase prolongada de la enfermedad.

Purpose. To systematize the evidence regarding the effectiveness of rehabilitation programs, based on the prescription of physical exercise, applied in older people with persistent symptoms of COVID-19. Methods. The PubMed, Science Direct, SPORTDiscus, MEDLINE Complete and Web of Science databases were reviewed. Randomized controlled trial-type studies with a publication date from 2020 to October 2022 and that were focused on physical exercise-based rehabilitation programs that were applied to individuals over or equal to 60 years of age who manifest persistent COVID-19 symptoms post-acute phase. Results. Two randomized controlled trials, which measured the effectiveness of physical exercise-based rehabilitation in elderly people (over or equal to 60 years), were identified. The results showed improvement in exercise tolerance, respiratory function, and psychological well-being in older adults with post-COVID-19 symptoms. However, the number of studies is low and the representation of this age group, too. Conclusion. Physical exercise-based rehabilitation programs in older people are effective in treating post-COVID-19 symptoms. More high-quality comparative studies are needed, in older people, to develop rehabilitation programs that allow coping with the prolonged phase of the disease.

Photobiomodulation efficacy of major salivary glands in children with caries activity: study protocol for randomized, double-blind, placebo-controlled, parallel-group clinical trial / Efeito da fotobiomodulação das principais glândulas salivares em crianças com actividade de cárie: ensaio clínico aleatório duplo-cego

Background: Dental caries is one of the most prevalent diseases among children worldwide. Saliva plays a significant role in the demineralization/remineralization of the dental surface. Several salivary characteristics, such as flow rate, pH, and buffering capacity, provide relevant information regarding the development of carious lesions. Photobiomodulation has shown promising results in improving salivary flow rate and buffer capacity in the adult population. Purpose: of this trial was to evaluate the efficacy of photobiomodulation of the major salivary glands on salivary parameters in children with caries. Methods: This protocol details a randomized, double-blind, parallel-group, controlled trial that evaluated salivary parameters through photobiomodulation in children. Fifty 6- to 12-year-old participants will be randomly divided into two groups:1) photobiomodulation experimental group (G1) (n=25) and 2) photobiomodulation placebo group (G2) (n=25). Infrared light will be applied at 16 intra-and extraoral points and placebo, respectively. Unstimulated salivary samples will be collected before and immediately after application once a week for three consecutive weeks. Salivary samples will be analyzed for their flow rate, pH, and buffering capacity. The primary outcomes are the differences in salivary flow rates between G1 and G2. The secondary outcomes are differences in salivary pH and buffering capacity between G1 and G2. Discussion: The results of this clinical trial will offer evidence for the efficacy of photobiomodulation in salivary parameters and to support decision-making regarding non-invasive treatments to control dental caries.

Contexto: A cárie dentária é uma das doenças mais prevalentes entre as crianças em todo o mundo. A saliva desempenha um papel significativo na desmineralização/remineralização da superfície dentária. Várias características salivares, como a taxa de fluxo, o pH e a capacidade de tamponamento, fornecem informações relevantes sobre o desenvolvimento de lesões de cárie. A fotobiomodulação demonstrou resultados promissores na melhoria da taxa de fluxo salivar e da capacidade de tamponamento na população adulta. Objetivo: deste estudo foi avaliar a eficácia da fotobiomodulação das glândulas salivares principais sobre os parâmetros salivares em crianças com cárie. Métodos: Este protocolo detalha um estudo randomizado, duplo-cego, de grupos paralelos e controlado que avaliou parâmetros salivares por meio da fotobiomodulação em crianças. Cinquenta participantes de 6 a 12 anos de idade serão divididos aleatoriamente em dois grupos: 1) grupo experimental de fotobiomodulação (G1) (n=25) e 2) grupo placebo de fotobiomodulação (G2) (n=25). A luz infravermelha será aplicada em 16 pontos intra e extraorais e o placebo, respectivamente. Amostras salivares não estimuladas serão coletadas antes e imediatamente após a aplicação, uma vez por semana, durante três semanas consecutivas. As amostras salivares serão analisadas quanto à sua taxa de fluxo, pH e capacidade de tamponamento. Os resultados primários são as diferenças nas taxas de fluxo salivar entre G1 e G2. Os resultados secundários são as diferenças no pH salivar e na capacidade de tamponamento entre G1 e G2. Discussão: Os resultados desse ensaio clínico oferecerão evidências da eficácia da fotobiomodulação nos parâmetros salivares e apoiarão a tomada de decisões em relação a tratamentos não invasivos para o controle da cárie dentária.

From awareness to action: Effects of a school-based intervention on TV viewing behavior stages and screen time guidelines knowledge in Brazilian adolescents / Da conscientização à ação: Efeitos de uma intervenção escolar nos estágios de mudança de comportamento para assistir TV e no conhecimento das diretrizes de tempo de tela em adolescentes brasileiros

The aims of the study were to verify the effect of an intervention on the stage of behavior change for TV viewing and to identify the possible mediating role of knowledge on screen time guidelines among Brazilian students. This study is a multicomponent school-based intervention conducted with 727 students (54.3% female, 13 years; 427 in the intervention group and 300 in the control group). The intervention was performed in 2017 with baseline and post-intervention assessments (over one academic year). Teacher training was carried out at the beginning of the intervention along with en-vironmental improvements, while educational curriculum such as the delivery of folders and posters were performed throughout the year. The stages of behavior change for TV viewing and knowledge of screen time guidelines were measured by a self-reported questionnaire and the structural equation modeling approach was performed. The intervention had no significant effects on stages of behavior change for TV (p = 0.744) nor did it result in significant changes on knowledge of screen time guide-lines (p = 0.741). While there was no mediation between knowledge of screen time guidelines and the effect of the intervention on stages of behavior change for TV (95%CI: -0.45;0.63), an associa-tion was found between knowledge of screen time guidelines and stages of behavior change for TV (p<0.001). In conclusion, intervention had no significant effect on the stages of behavior change for TV and no mediating effect was observed. However, enhancing awareness on screen time guidelines may positively impact the adolescent's intention to reduce TV time

Os objetivos do estudo foram verificar o efeito de uma intervenção nos estágios de mudança de comporta-mento para assistir TV e identificar o papel mediador do conhecimento sobre as recomendações de tempo de tela. A intervenção multicomponente, randomizada e controlada obteve a participação de 727 alunos em 2017 (54,3% meninas, 13 anos; 427 no grupo intervenção e 300 no grupo controle). A formação dos pro-fessores foi realizada no início da intervenção juntamente com as melhorias ambientais, enquanto as ações educativas foram realizadas ao longo do ano. Os estágios de mudança de comportamento para assistir TV e o conhecimento sobre as recomendações do tempo de tela foram mensurados por questionário auto reportado, pré e pós-intervenção (um ano letivo). Para análise dos dados foi realizada uma modelagem de equações estru-turais. Não houve efeito da intervenção nos estágios de mudança de comportamento para TV (p = 0,744) e também não houve mudanças significativas no conhecimento dos estudantes sobre as recomendações do tempo de tela (p = 0,741). Embora não tenha havido mediação entre conhecimento das recomendações do tempo de tela e o efeito da intervenção nos estágios de mudança de comportamento para TV (IC95%: -0,45;0,63), foi encontrada associação entre o conhecimento das recomendações e os estágios de mudança de comportamento para TV (p < 0,001). Conclui-se que a intervenção não teve efeito significativo nos estágios de mudança de comportamento para TV e efeito mediador. No entanto, aumentar a conscientização sobre as recomendações de tempo de tela pode impactar positivamente na intenção do adolescente de reduzir o tempo de TV

Treinamento de força com e sem instabilidade não melhora os níveis gerais de capacidade intrínseca em idosos com queixas cognitivas / Resistance training with and without instability does not improve overall levels of intrinsic capacity in older adults with cognitive complaints

INTRODUÇÃO: Capacidade intrínseca (CI) é um construto que engloba capacidades físicas e mentais para o autocuidado e envelhecimento saudável. A compreensão do papel potencial do treinamento resistido, com e sem instabilidade, para promover o CI precisa ser esclarecida. OBJETIVO: Avaliar o impacto do treinamento de força sobre os níveis de capacidade intrínseca em idosos com queixas cognitivas. MÉTODOS: Idosos com queixas cognitivas (n=67) foram aleatoriamente designados para 12 semanas de TF tradicional (n=23), TF com dispositivos de instabilidade (TFI) (n=22) ou controle (n=22). Ambos os grupos de treinamento realizaram três séries de 10- 15 repetições. O grupo TFI realizou exercícios utilizando dispositivos de instabilidade. O grupo controle recebeu aulas semanais de educação em saúde. Os domínios da CI foram de mobilidade e velocidade da marcha (locomotora), função global e executiva (cognitivo), força de preensão e teste de caminhada de seis minutos (vitalidade), e sintomas depressivos e autoeficácia (psicológicos) por meio de escores-z compostos. Calculamos os níveis globais de CI pela soma de cada pontuação composta. RESULTADOS: Diferença significativa intragrupo nos níveis gerais de CI (∆TFI = +1.69, ∆TF = +1.30) e seus respectivos domínios (Locomoção: ∆TFI = +2.32, ∆TF = +3.21; Cognição: ∆TFI = +2.31; Vitalidade: ∆TFI = +1.23, ∆TF = +1.42; e Psicológico: ∆TFI = -0.65, ∆TF = -0.62). Contudo, não houve diferenças entre os grupos. Análise de sensibilidade mesclando os grupos de treinamento revelou diferença significativa para o domínio locomotor após 12 semanas (+1.97, p=0.045). CONCLUSÃO: Treinamento de força com e sem dispositivos de instabilidade não melhorou os níveis de CI em idosos com queixas cognitivas.

INTRODUCTION: Intrinsic capacity (IC) is a construct that encompasses physical and mental capacities important for self-care and healthy aging. Understanding the potential role of resistance training with and without instability to promote IC needs to be clarified. OBJECTIVE: To assess the impact of resistance training on intrinsic capacity levels in older adults with cognitive complaints. METHODS: Older adults with cognitive complaints (n=67) were randomly assigned to either 12 weeks of traditional RE (n=23), RE with instability devices (REI) (n=22), or control (n=22). Both training groups performed three sets of 10-15 repetitions. REI group performed each exercise using instability devices. The control group received weekly health education classes. IC domains were analyzed using mobility and gait velocity (locomotor), global and executive functioning (cognitive), grip strength and six-minute walking test (vitality), and depressive symptoms and self-efficacy (psychological) through z-composite scores. We computed global levels of IC by the sum of each composite score. RESULTS: A significant within-group difference (improvement) in overall levels of IC (∆REI = +1.69, ∆RE = +1.30) and all their domains (Locomotion: ∆REI = +2.32, ∆RE = +3.21; Cognition: ∆REI = +2.31; Vitality: ∆REI = +1.23, ∆RE = +1.42; and Psychological: ∆REI = -0.65, ∆RE = -0.62). However, no between-group differences were observed at the completion of the trial. Sensitivity analysis merging training groups revealed a between-group difference for the locomotor domain (+1.97, p=0.045). CONCLUSION: Resistance training with and without instability devices did not improve IC levels among older adults with cognitive complaints.

Estrógeno potenciado en el tratamiento homeopático del dolor pélvico asociado a endometriosis: un estudio aleatorizado, doble ciego, controlado con placebo, de 24 semanas / Potentiated estrogen in the homeopathic treatment of pelvic pain associated with endometriosis: a 24-week randomized, double-blind, placebo-controlled study

Evaluar la eficacia y seguridad del estrógeno potenciado en comparación con el placebo en el tratamiento homeopático del dolor pélvico asociado a endometriosis (EAPP, por sus siglas en inglés). Diseño del estudio: El presente fue un estudio clínico aleatorizado, doble ciego, controlado con placebo, de 24 semanas, el cual incluyó a 50 mujeres de entre 18 y 45 años de edad con diagnóstico de endometriosis infiltrante profunda con base en ultrasonido transvaginal o imágenes de resonancia magnética después de preparación intestinal, así como puntaje ≥ 5 en una escala visual analógica (VAS: rango de 0 a 10 puntos) para el dolor pélvico asociado con la endometriosis. Se administró estrógeno potenciado (12cH, 18cH y 24cH) o placebo dos veces al día por vía oral. La medida principal de resultado fue el cambio en la severidad de los puntajes parcial y global de EAPP (VAS) de la línea basal a la semana 24, determinada como la diferencia en el puntaje medio de cinco modalidades de dolor pélvico crónico (dismenorrea, dispareunia profunda, dolor pélvico no cíclico, dolor intestinal cíclico y/o dolor urinario cíclico). Las medidas secundarias de resultado fueron la diferencia media de puntaje para la calidad de vida evaluada con el Cuestionario de Salud SF-36, los síntomas de depresión en el Inventario de la Depresión de Beck (BDI) y los síntomas de ansiedad en el Inventario de Ansiedad de Beck (BAI). Resultados: El puntaje global de EAPP (VAS: rango de 0 a 50 puntos) se redujo en 12.82 (p < 0.001) en el grupo tratado con estrógeno potenciado de la línea basal a la semana 24. El grupo que utilizó estrógeno potenciado también presentó una reducción en el puntaje parcial (VAS: rango de 0 a 10 puntos) en tres modalidades de EAPP: dismenorrea (3.28; p < 0.001), dolor pélvico no cíclico (2.71; p = 0.009) y dolor intestinal cíclico (3.40; p < 0.001). El grupo de placebo no mostró cambio significativo alguno en los puntajes global o parcial de EAPP. Además, el grupo de estrógeno potenciado mostró un mejoramiento significativo en tres de ocho ámbitos de SF-36 (dolor de cuerpo, vitalidad y salud mental) y síntomas de depresión (BDI). El grupo de placebo no mostró un mejoramiento significativo a este respecto. Estos resultados demuestran la superioridad del estrógeno potenciado sobre el placebo. Se asociaron pocos eventos adversos con el estrógeno potenciado. Conclusiones: El estrógeno potenciado (12cH, 18cH y 24cH) en dosis de 3 gotas dos veces al día durante 24 semanas fue significativamente más efectivo que el placebo para reducir el dolor pélvico asociado con la endometriosis.

To evaluate the efficacy and safety of potentized estrogen compared to placebo in homeopathic treatment of endometriosis-associated pelvic pain (EAPP). Study design: The present was a 24-week, randomized, doubleblind, placebocontrolled trial that included 50 women aged 18-45 years old with diagnosis of deeply infiltrating endometriosis based on magnetic resonance imaging or transvaginal ultrasound after bowel preparation, and score ≥ 5 on a visual analogue scale (VAS: range 0 to 10 points) for endometriosis-associated pelvic pain. Potentized estrogen (12cH, 18cH and 24cH) or placebo was administered twice daily per oral route. The primary outcome measure was change in the severity of EAPP global and partial scores (VAS) from baseline to week 24, determined as the difference in the mean score of five modalities of chronic pelvic pain (dysmenorrhea, deep dyspareunia, non-cyclic pelvic pain, cyclic bowel pain and/or cyclic urinary pain). The secondary outcome measures were mean score difference for quality of life assessed with SF-36 Health Survey Questionnaire, depression symptoms on Beck Depression Inventory (BDI), and anxiety symptoms on Beck Anxiety Inventory (BAI). Results: The EAPP global score (VAS: range 0 to 50 points) decreased by 12.82 (p < 0.001) in the group treated with potentized estrogen from baseline to week 24. Group that used potentized estrogen also exhibited partial score (VAS: range 0 to 10 points) reduction in three EAPP modalities: dysmenorrhea (3.28; p < 0.001), non-cyclic pelvic pain (2.71; p = 0.009), and cyclic bowel pain (3.40; p < 0.001). Placebo group did not show any significant changes in EAPP global or partial scores. In addition, the potentized estrogen group showed significant improvement in three of eight SF-36 domains (bodily pain, vitality and mental health) and depression symptoms (BDI). Placebo group showed no significant improvement in this regard. These results demonstrate superiority of potentized estrogen over placebo. Few adverse events were associated with potentized estrogen. Conclusions: Potentized estrogen (12cH, 18cH and 24cH) at a dose of 3 drops twice daily for 24 weeks was significantly more effective than placebo for reducing endometriosis-associated pelvic pain.

O impacto das intervenções de meditação breve e extremamente breve nas taxas de sucesso de Técnicas de Reprodução Assistida: um estudo controlado randomizado / The impact of brief and extremely brief meditation interventions on the success rates of Assisted Reproductive Techniques: a randomized controlled trial

Introdução: As taxas de sucesso da gravidez com as técnicas de reprodução assistida (ART) têm melhorado constantemente. O efeito das intervenções não farmacológicas, como a meditação, como terapias adjuvantes, nos resultados dos ciclos de ART tem sido pesquisado com resultados promissores. No entanto, até onde sabemos, há muitas dúvidas sobre os efeitos os efeitos de meditação breve e extremamente breve nas taxas de sucesso em ART. Portanto, uma meditação extremamente breve guiada por facilitador e uma meditação breve em formato de áudio e autogerenciada foram estudadas. Objetivo: Investigar o efeito das intervenções da meditação breve (IMB) e extremamente breve (IMEB) na taxa de gravidez em mulheres submetidas à Tecnologia de Reprodução Assistida (TRA). Método: Trata-se de um estudo prospectivo, randomizado, controlado com três braços. As intervenções foram realizadas no período de espera entre a transferência de embriões e o teste de gravidez ß-hCG. O tamanho da amostra foi calculado pelo qui-quadrado de Pearson com base no poder de 80%, tamanho do efeito de 0,4 e nível de confiança de 95%. As variáveis relacionadas ao sucesso da TRA foram incluídas na análise: idade em anos, número de embriões/blastocistos transferidos, número de embriões/blastocistos com qualidade excelente ou muito boa, número de ciclos de fertilização in vitro, faixa etária e se foi transferido embrião ou blastocisto. O teste qui-quadrado (χ2) e ANOVA compararam os valores das variáveis entre os grupos de intervenções e controle. A Análise de Regressão Logística Univariada avaliou se cada variável relacionada ao sucesso da TRA influenciou ou não a resposta da variável de desfecho "gravidez". Utilizou-se Análise de Regressão Logística Múltipla para avaliar a influência dessas variáveis em conjunto no desfecho da gravidez. Resultados: Foram incluídas 68 mulheres com idade de 37,5+4,3 anos (IMEB, n=24; IMB n=22 e GC, n=22). O teste qui-quadrado de Pearson e o teste t de Student para amostras independentes mostraram que não houve diferenças significativas (p<0,05) entre os grupos intervenção e grupo controle. Tanto a IMEB quanto a IMB não tiveram efeito significativo na taxa de gravidez em mulheres submetidas à ART. Conclusão: O uso da meditação breve ou extremamente breve não demonstrou diferenças significativas na taxa de gravidez entre os grupos intervenção e grupo controle, em mulheres sob tratamento com Técnicas de Reprodução Assistida. Os resultados dos efeitos da meditação na taxa de gravidez de mulheres em TRA são inconclusivos na literatura. Necessita-se de ensaios controlados randomizados com amostras maiores comparando ambas as intervenções de meditações breves e extremamente breves a um grupo controle para confirmar os achados deste estudo.

Introduction: Pregnancy success rates with assisted reproductive technology (ART) have steadily improved. The effect of non-pharmacological interventions such as meditation as adjunctive therapies on the outcomes of ART cycles has been researched with promising results. However, to the best of our knowledge, there is much doubt about the effects of brief and extremely brief meditation on ART success rates. Therefore, an extremely brief facilitatorguided meditation and an audio-guided, self-paced short meditation were studied. Objectives: To investigate the effect of extremely brief meditation (EBMI) or brief mindfulness interventions (Brief MI) on pregnancy rate in women undergoing Assisted Reproductive Technology (ART). Method: This is a prospective three arms randomized, controlled study. Interventions were performed in the waiting period between embryo transfer and the ß-hCG pregnancy test. The sample size was calculated using Pearson's chi-square based on a power of 80%, effect size of 0.4 and a confidence level of 95%. Variables related to the success of ART included in the analysis consisted of age in years, number of embryos/blastocysts transferred, number of embryos/blastocysts with excellent or very good quality, number of in vitro fertilization cycles, age range, and whether the embryo was transferred or blastocyst. Chi-square test (χ2) and ANOVA compared variable values between intervention and control groups. Univariate Logistic Regression Analysis evaluated whether each variable related to ART success influenced or not the response of the outcome variable "pregnancy". Multiple Logistic Regression Analysis assessed if these variables could influence jointly the outcome of pregnancy. Results: A total of 68 women aged 37.5+4.3y were included (EBMI, n=24; Brief MI, n=22 and CG, n=22) were. Pearson's Chi-square test and Student's t test for independent samples showed that there were no significant differences (p<0.05) between the intervention groups and control group. Both EBMI and BMI had no significant effect on pregnancy rate in women undergoing ART. Conclusion: The use of brief or extremely brief meditation did not demonstrate significant differences in the pregnancy rate between the intervention and control groups in women undergoing treatment with Assisted Reproductive Techniques. The results of the effects of meditation on the pregnancy rate of women on ART are inconclusive in the literature. Larger sample randomized controlled trials comparing both brief and extremely brief meditation interventions to a control group are needed to confirm the findings of this study.

Effect of cardiovascular biofeedback on nursing staff stress: a randomized controlled clinical trial / Efecto del biofeedback cardiovascular sobre el estrés del personal de enfermería: un ensayo clínico controlado aleatorizado / Efeito do biofeedback cardiovascular no estresse da equipe de enfermagem: ensaio clínico controlado aleatório

ABSTRACT Objective: to assess the effect of cardiovascular biofeedback on nursing staff stress when compared to an activity without self-monitoring. Method: a randomized controlled clinical trial, carried out with nursing professionals from a university hospital. The intervention group (n=58) performed cardiovascular biofeedback, and the control (n=57) performed an online puzzle without self-monitoring, totaling nine meetings over three weeks. The outcome was assessed using the Stress Symptoms and Work-Related Stress scales, and the biological marker heart rate variability. The generalized estimating equations method was used. Results: the intervention had no effect on self-reported instruments (p>0.050). However, there was an effect of time (p<0.050) on all heart rate variability indicators, demonstrating changes over the sessions. Conclusion: cardiovascular biofeedback showed promising results in the biological marker, suggesting that it can be used in nursing staff as a complementary therapy by promoting better autonomic nervous system regulation.

Treatment effects and lip profile changes following premolars extraction treatment vs fixed functional treatment in Class II division 1 malocclusion: A randomized controlled clinical trial

ABSTRACT Objective: The objective of this two-arm parallel randomized controlled trial was to evaluate the treatment effects and lip profile changes in skeletal Class II patients subjected to premolars extraction treatment versus fixed functional treatment. Methods: Forty six subjects fulfilling inclusion criteria were randomly distributed into Group PE (mean age 13.03±1.78 years) and Group FF (mean age 12.80±1.67 years) (n=23 each). Group PE was managed by therapeutic extraction of maxillary first premolars and mandibular second premolars, followed by mini-implant-supported space closure; and Group FF, by fixed functional appliance therapy. Skeletal, dental, and soft-tissue changes were analyzed using pre and post-treatment lateral cephalograms. Data obtained from this open label study was subjected to blind statistical analysis. Results: Extraction treatment resulted in greater increase of nasolabial angle (NLA: 3.1 [95% CI 2.08, 4.19], p<0.001), significant improvement of upper lip (UL-E line: -2.91 [95% CI -3.54, -2.28], p<0.001, UL-S line: -2.50 [95% CI -2.76, -2.24], p<0.001, UL-SnPog': -2.32 [95% CI -2.90, -1.74], p<0.01) and lower lip position (LL-E line: -0.68 [95% CI -1.36, 0.00], p<0.01, LL-S line: -0.55 [95% CI -1.11, 0.02], p<0.01, and LL-SnPog': -0.64 [95% CI -1.20, -0.07], p<0.01), lip thickness (UL thickness: 2.27 [95% CI 1.79, 2.75], p<0.001; LL thickness: 0.41 [95% CI -0.16, 0.97], p<0.01), upper lip strain (UL strain: -2.68 [95% CI -3.32, -2.04], p<0.001) and soft tissue profile (N'-Sn-Pog': 2.68 [95% CI 1.87, 3.50], p<0.01). No significant difference was observed between the groups regarding skeletal changes in the maxilla and mandible, growth pattern, overjet, overbite, interincisal angle and soft tissue chin position (p>0.05). Premolar extraction treatment demonstrated significant intrusion-retraction of maxillary incisors, better maintenance of maxillary incisor inclination, and significant mandibular molar protraction; whereas functional treatment resulted in retrusive and intrusive effect on maxillary molars, marked proclination of mandibular anterior teeth, and significant extrusion of mandibular molars. Both treatment modalities had similar treatment duration. Implant failure was seen in 7.9% of cases, whereas failure of fixed functional appliance was observed in 9.09% of cases. Conclusions: Premolar extraction therapy is a better treatment modality, compared to fixed functional appliance therapy for Class II patients with moderate skeletal discrepancy, increased overjet, protruded maxillary incisors and protruded lips, as it produces better dentoalveolar response and permits greater improvement of the soft tissue profile and lip relationship.

RESUMO Objetivo: O objetivo desse estudo randomizado controlado paralelo de dois braços foi avaliar os efeitos do tratamento e as mudanças no perfil labial em pacientes esqueléticos Classe II submetidos a tratamento com extração de pré-molares (EP) versus tratamento funcional fixo (FF). Métodos: Quarenta e seis indivíduos que preencheram os critérios de inclusão foram distribuídos aleatoriamente em Grupo EP (idade média 13,03±1,78 anos) e Grupo FF (idade média 12,80±1,67 anos) (n=23 cada). O grupo EP foi tratado com extração dos primeiros pré-molares superiores e segundos pré-molares inferiores, seguida de fechamento do espaço com ancoragem em mini-implantes; e o Grupo FF, com tratamento usando aparelhos funcionais fixos. As alterações esqueléticas, dentárias e de tecidos moles foram analisadas usando cefalogramas laterais pré e pós-tratamento. Os dados obtidos desse estudo aberto foram submetidos a análise estatística cega. Resultados: O tratamento com extrações resultou em maior aumento do ângulo nasolabial (ANL: 3,1 [IC 95% 2,08, 4,19], p<0,001), melhora significativa do lábio superior (Ls-Linha E: -2,91 [IC 95% -3,54, -2,28], p<0,001, Ls-Linha S: -2,50 [IC 95% -2,76, -2,24], p<0,001, Ls-SnPog': -2,32 [IC 95% -2,90, -1,74], p<0,01) e posição do lábio inferior (Li-Linha E: -0,68 [IC 95% -1,36, 0,00], p<0,01, Li-Linha S: -0,55 [IC 95% -1,11, 0,02], p<0,01, e Li-SnPog': -0,64 [IC 95% -1,20, -0,07], p<0,01), espessura dos lábios (espessura Ls: 2,27 [IC 95% 1,79, 2,75], p<0,001; espessura Li: 0,41 [IC 95% -0,16, 0,97], p<0,01), tensão do lábio superior (tensão Ls: -2,68 [IC 95% -3,32, -2,04], p<0,001) e perfil de tecidos moles (N'-Sn-Pog': 2,68 [IC 95% 1,87, 3,50], p<0,01). Nenhuma diferença significativa foi observada entre os grupos quanto às alterações esqueléticas na maxila e mandíbula, padrão de crescimento, sobressaliência, sobremordida, ângulo interincisal e posição dos tecidos moles do mento (p>0,05). O tratamento com extração de pré-molares demonstrou significativa intrusão-retração dos incisivos superiores, melhor manutenção da inclinação dos incisivos superiores e protração significativa dos molares inferiores; enquanto o tratamento funcional resultou em efeito retrusivo e intrusivo nos molares superiores, proclinação acentuada dos dentes anteriores inferiores e extrusão significativa dos molares inferiores. Ambas as modalidades de tratamento tiveram duração de tratamento semelhante. A falha do mini-implante foi observada em 7,9% dos casos, enquanto a falha do aparelho funcional fixo foi observada em 9,09% dos casos. Conclusões: O tratamento com extração de pré-molares é uma modalidade de tratamento melhor do que os aparelhos funcionais fixos para pacientes Classe II com discrepância esquelética moderada, sobressaliência aumentada, incisivos superiores protruídos e lábios protruídos, pois produz melhor resposta dentoalveolar e permite maior melhora do perfil dos tecidos moles e relacionamento labial.

Clinical performance of an alkasite-based bioactive restorative in class II cavities: a randomized clinical trial

Abstract Objective This clinical study aimed to evaluate the clinical performance of an alkasite-based bioactive material by comparing it with a resin composite (RC) in the restoration of Class II cavities over a year. Methodology A hundred Class II cavities were restored at 31 participants. Groups were as follows: Cention N (CN) (Ivoclar Vivadent, Schaan, Liechtenstein) and G-ænial Posterior (GP) (GC, Tokyo, Japan) in combination with G-Premio Bond (etch&rinse). Restorative systems were applied following manufacturers' instructions. They were finished and polished immediately after placement and scored based on retention, marginal discoloration, marginal adaptation, sensitivity, surface texture, and color match using modified USPHS criteria after 1 week (baseline), 6 months, and 12 months. Statistical analyses were performed using chi-square, McNemar's, and Kaplan Meier tests. Results After 12 months, the recall rate was 87%. Survival rates of CN and GP restorations were 92.5% and 97.7%, respectively. Three CN and one GP restorations lost retention. Seven CN (17.9%) and five (11.6%) GP restorations were scored as bravo for marginal adaptation and no significant difference was seen between groups (p=0.363). One (2.7%) CN and two GP (4.7%) restorations were scored as bravo for marginal discoloration, but no significant difference was observed between groups(p=1.00). For surface texture, three (8.1%) CN and three (7%) GP restorations were scored as bravo (p=1.00). None of the restorations demonstrated post-operative sensitivity or secondary caries at any examinations. Conclusion The tested restorative materials performed similar successful clinical performances after 12 months. ClinicalTrials.gov (NTC04825379).

Systematic review and Meta-analysis of Gusongbao preparation in treatment of primary osteoporosis / 中国中药杂志

This study aims to provide evidence for clinical practice by systematically reviewing the efficacy and safety of Gusongbao preparation in the treatment of primary osteoporosis(POP). The relevant papers were retrieved from four Chinese academic journal databases and four English academic journal databases(from inception to May 31, 2022). The randomized controlled trial(RCT) of Gusongbao preparation in the treatment of POP was included after screening according to the inclusion and exclusion criteria. The quality of articles was evaluated using risk assessment tools, and the extracted data were subjected to Meta-analysis in RevMan 5.3. A total of 657 articles were retrieved, in which 15 articles were included in this study, which involved 16 RCTs. A total of 3 292 patients(1 071 in the observation group and 2 221 in the control group) were included in this study. In the treatment of POP, Gusongbao preparation+conventional treatment was superior to conventional treatment alone in terms of increasing lumbar spine(L2-L4) bone mineral density(MD=0.03, 95%CI[0.02, 0.04], P<0.000 01) and femoral neck bone mineral density, reducing low back pain(MD=-1.69, 95%CI[-2.46,-0.92], P<0.000 1) and improving clinical efficacy(RR=1.36, 95%CI[1.21, 1.53], P<0.000 01). Gusongbao preparation was comparable to similar Chinese patent medicines in terms of improving clinical efficacy(RR=0.95, 95%CI[0.86, 1.04], P=0.23). Gusongbao preparation was inferior to similar Chinese patent medicines in reducing traditional Chinese medicine syndrome scores(MD=1.08, 95%CI[0.44, 1.71], P=0.000 9) and improving Chinese medicine syndrome efficacy(RR=0.89, 95%CI[0.83, 0.95], P=0.000 4). The incidence of adverse reactions of Gusongbao preparation alone or combined with conventio-nal treatment was comparable to that of similar Chinese patent medicines(RR=0.98, 95%CI[0.57, 1.69], P=0.94) or conventio-nal treatment(RR=0.73, 95%CI[0.38, 1.42], P=0.35), and the adverse reactions were mainly gastrointestinal discomforts. According to the available data, Gusongbao preparation combined with conventional treatment is more effective than conventional treatment alone in increasing lumbar spine(L2-L4) bone mineral density and femoral neck bone mineral density, reducing low back pain, and improving clinical efficacy. The adverse reactions of Gusongbao preparation were mainly gastrointestinal discomforts, which were mild.

Two researchers independently conducted literature screening, data extraction, and risk of bias assessment according to pre-established inclusion and exclusion criteria. RevMan 5.4.1 was used for data analysis. Finally, 18 RCTs were included, involving 3 489 patients. Meta-analysis showed that compared with conventional western medicine, Fengliao Changweikang prescription improved the relief rate of abdominal pain(RR=1.27, 95%CI[1.17, 1.38],P<0.000 01); Fengliao Changweikang prescription + conventional western medicine increased the cure rate(RR=1.43, 95%CI[1.12, 1.82], P=0.004), shortened the duration of diarrhoea(RR=-1.65, 95%CI[-2.44,-0.86], P<0.000 1), abdominal pain(RR=-1.46, 95%CI[-2.00,-0.92], P<0.000 01), vomiting(RR=-2.16, 95%CI[-2.51,-1.81], P<0.000 01) and fever(RR=-2.61, 95%CI[-4.00,-1.23], P=0.000 2), down-regulated the level of interleukin-8(IL-8)(RR=-1.07, 95%CI[-1.26,-0.88], P<0.000 01), IL-6(RR=-8.24, 95%CI[-8.99,-7.49], P<0.000 01) and hypersensitive C-reactive protein(hs-CRP)(RR=-3.04, 95%CI[-3.40,-2.69], P<0.000 01) and recurrence of AGE(RR=0.20, 95%CI[0.05, 0.90], P<0.04). In conclusion, Fengliao Changweikang prescription was safe in clinical application. It was beneficial to alleviate the clinical symptoms of diarrhea, abdominal pain, vomiting, and fever, and down-regulate the levels of some serum inflammatory factors in AGE patients. However, considering that few high-quality studies have evaluated the efficacy and safety of Fengliao Changweikang prescription in treatment of AGE, further evidence is needed in the future.
