Acupuncture for generalized anxiety disorder: a study protocol for a randomized controlled trial

During the COVID-19 outbreak, there was a sharp increase in generalized anxiety disorder (GAD). Acupuncture therapy has the advantages of accurate clinical efficacy, safety and reliability, few adverse reactions, and no dependence, and is gradually becoming one of the emerging therapies for treating GAD. We present a study protocol for a randomized clinical trial with the aim of exploring the mechanism of brain plasticity in patients with GAD and evaluate the effectiveness and reliability of acupuncture treatment. Transcranial magnetic stimulation (TMS) will be used to assess cortical excitability in GAD patients and healthy people. Sixty-six GAD patients meeting the inclusion criteria will be randomly divided into two groups: TA group, (treatment with acupuncture and basic western medicine treatment) and SA group (sham acupuncture and basic western medicine treatment). Twenty healthy people will be recruited as the control group (HC). The parameters that will be evaluated are amplitude of motor evoked potentials (MEPs), cortical resting period (CSP), resting motor threshold (RMT), and Hamilton Anxiety Scale (HAMA) score. Secondary results will include blood analysis of γ-aminobutyric acid (GABA), glutamate (Glu), glutamine (Gln), serotonin (5-HT), and brain-derived nerve growth factor (BDNF). Outcomes will be assessed at baseline and after the intervention (week 8). This study protocol is the first clinical trial designed to detect differences in cerebral cortical excitability between healthy subjects and patients with GAD, and the comparison of clinical efficacy and reliability before and after acupuncture intervention is also one of the main contents of the protocol. We hope to find a suitable non-pharmacological alternative treatment for patients with GAD.

Effect size varies based on calculation method and may affect interpretation of treatment effect: an illustration using randomised clinical trials in osteoarthritis

Abstract Background To illustrate how (standardised) effect sizes (ES) vary based on calculation method and to provide considerations for improved reporting. Methods Data from three trials of tanezumab in subjects with osteoarthritis were analyzed. ES of tanezumab versus comparator for WOMAC Pain (outcome) was defined as least squares difference between means (mixed model for repeated measures analysis) divided by a pooled standard deviation (SD) of outcome scores. Three approaches to computing the SD were evaluated: Baseline (the pooled SD of WOMAC Pain values at baseline [pooled across treatments]); Endpoint (the pooled SD of these values at the time primary endpoints were assessed); and Median (the median pooled SD of these values based on the pooled SDs across available timepoints). Bootstrap analyses were used to compute 95% confidence intervals (CI). Results ES (95% CI) of tanezumab 2.5 mg based on Baseline, Endpoint, and Median SDs in one study were - 0.416 (- 0.796, - 0.060), - 0.195 (- 0.371, - 0.028), and - 0.196 (- 0.373, - 0.028), respectively; negative values indicate pain improvement. This pattern of ES differences (largest with Baseline SD, smallest with Endpoint SD, Median SD similar to Endpoint SD) was consistent across all studies and doses of tanezumab. Conclusion Differences in ES affect interpretation of treatment effect. Therefore, we advocate clearly reporting individual elements of ES in addition to its overall calculation. This is particularly important when ES estimates are used to determine sample sizes for clinical trials, as larger ES will lead to smaller sample sizes and potentially underpowered studies.

Do baseline participant characteristics impact the effectiveness of a mobile health intervention for depressive symptoms? A post-hoc subgroup analysis of the CONEMO trials

Objective: To ascertain whether sociodemographic and health-related characteristics known from previous research to have a substantive impact on recovery from depression modified the effect of a digital intervention designed to improve depressive symptoms (CONEMO). Methods: The CONEMO study consisted of two randomized controlled trials, one conducted in Lima, Peru, and one in São Paulo, Brazil. As a secondary trial plan analysis, mixed logistic regression was used to explore interactions between the treatment arm and subgroups of interest defined by characteristics measured before randomization - suicidal ideation, race/color, age, gender, income, type of mobile phone, alcohol misuse, tobacco use, and diabetes/hypertension - in both trials. We estimated interaction effects between the treatment group and these subgroup factors for the secondary outcomes using linear mixed regression models. Results: Increased effects of the CONEMO intervention on the primary outcome (reduction of at least 50% in depressive symptom scores at 3-month follow-up) were observed among older and wealthier participants in the Lima trial (p = 0.030 and p = 0.001, respectively). Conclusion: There was no evidence of such differential effects in São Paulo, and no evidence of impact of any other secondary outcomes in either trial. Clinical trial registration: NCT02846662 (São Paulo, Brazil - SP), NCT03026426 (Lima, Peru - LI). Funded by the U.S. National Institute of Mental Health (grant U19MH098780).

A randomized clinical trial comparing internal and external pessaries in the treatment of pelvic organ prolapse in postmenopausal women: A pilot study

Abstract Introduction and hypothesis Internal vaginal pessary is among the leading treatments for pelvic organ prolapse (POP); however, it has a high adverse event rate. An external pessary was recently developed as an alternative. The study's objective was to compare the efficacy of external and internal pessaries in treating POP in postmenopausal women. Methods This parallel randomized (1:1 ratio) open-blind study included 40 symptomatic women with stage 2 or 3 POP. They were randomized into two groups: group 1 (internal pessary) and group 2 (external pessary) (n = 20 in each); and evaluated at the start of and 3 months after the treatment. Statistical analysis was performed to compare the results within and between the groups before and after the 3-month treatment. Results The groups were homogeneous, except for the variables previous pregnancies (p = 0.030) and POP-Q score of apical prolapse (p = 0.023) whose values were higher in group 2. A significant improvement in quality of life was observed in both groups after 3 months of follow-up; however, internal pessaries were found to be more effective (p < 0.001). In group 1 there were differences between the initial and final POP-Q scores of anterior (0.004) and apical prolapse (p = 0.005). The complication rate associated with internal pessary use was high (p = 0.044). Conclusions The present data suggested that external pessaries have a similar effect to internal ones for the treatment of POP and improvement of the quality of life of postmenopausal women.

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.

Impact of Telemedicine use on clinical care indicators of pediatric intensive care units: protocol for a cluster randomized clinical trial / Impacto do uso da Telemedicina nos indicadores clínicos assistenciais de unidades de terapia intensiva pediátricas: protocolo para um ensaio clínico randomizado em cluster

ABSTRACT The objective of this study is to present the protocol of a cluster randomized clinical trial to be conducted through the TeleICU project - Qualification of Intensive Care by Telemedicine. The study will consist of a cluster randomized clinical trial, open label, in pediatric intensive care units, with an allocation ratio of 1:1, to compare the intervention group (support of Telemedicine for patients admitted to the pediatric intensive care unit) with a control group (pediatric intensive care unit usual care). The study proposed to select 16 pediatric intensive care units, including 100 participants per site, with a total of 1,600 participants. The intervention group will receive telerounds from Monday to Friday and will have specialists and continuing education activities available. The primary outcome measure will be the length of stay in the pediatric intensive care unit, defined as the difference between the date of discharge of the participant and the date of admission to the intensive care unit. The secondary outcomes will be mortality rate, invasive mechanical ventilation-free days, days using antibiotics, days using vasoactive drugs and days using sedoanalgesia. This study will be conducted in accordance with Resolution 466/12 of the National Health Council, with approval by the Research Ethics Committee of the institutions involved. The present study has the potential to reproduce studies on Telemedicine in intensive care and may make important contributions to care in intensive care units in Brazil and other settings. If Telemedicine shows positive clinical care results compared to conventional treatment, more pediatric patients may benefit. ClinicalTrials.gov registry: NCT05260710

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.

Comparative efficacy and safety of six photoelectric therapies for the atrophic acne scars: A network meta-analysis

Objectives: This network meta-analysis assessed the relative efficacy and safety of six common photoelectric therapies including 1064-nm neodymium-doped yttrium aluminum garnet (Nd: YAG), fractional carbon dioxide laser(FSCO2), fractional micro-plasma radiofrequency(Plasma), micro-needling fractional radiofrequency (MRF), 1550nm or 1540nm erbium-glass non-ablative fractional laser (NAFL) fractional erbium-doped yttrium aluminum garnet (Er: YAG). Methods: A comprehensive search to identify relevant studies was conducted using four electronic databases. Outcome measures were extracted based on subjective and objective indexes, including the dermatologists’ evaluation(DE), the patients’ overall satisfaction(PS), VAS score, and Postinflammatory hyperpigmentation (PIH). Results: Eleven published clinical research studies, involving 405 patients were included in this study. Ranking of DE from large to small is as follows: Nd: YAG, FSCO2, Er: YAG, Plasma, NAFL, MRF. In terms of PS, the rand from high to low can be described as follows: Er: YAG, Nd: YAG, FSCO2, Plasma, NAFL, MRF. In connection with the sequencing of adverse events, pain severity from slight to severe as follows: Er:YAG, Nd:YAG, FSCO2, NAFL, MRF, Plasma. The probability of having PIH are presented in order from lowest to highest as follows: MRF, Plasma, Nd: YAG, NAFL, Er: YAG, FSCO2. Conclusion: FSCO2 remains the mainstream of potentially curative treatment, then again Nd: YAG and Er: YAG require greater efforts to prove their superior effectiveness. NAFL might be appropriate for mild and moderate improvement with its strengths of good tolerance while Plasma fits into patients with higher pain thresholds but an expectation of higher results. MRF has not given expression on absolute predominance for the present. Registration: PROSPERO CRD42021242160(available from https://www.crd.york.ac.uk/PROSPERO)

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.

La eficacia y seguridad del tratamiento homeopático fueron investigadas en niños con amigdalitis recurrente para la que se indicaba cirugía. Métodos: Estudio clínico prospectivo, aleatorizado, doble ciego, que incluyó 40 niños de entre 3 y 7 años de edad; 20 niños fueron tratados con medicación homeopática y otros 20 niños, con placebo. El seguimiento fue de 4 meses por niño. La evaluación de los resultados fue clínica mediante un cuestionario estándar y examen clínico el primer y último día de tratamiento. La amigdalitis recurrente se definió como ocurrencia de 5 a 7 episodios de amigdalitis bacteriana aguda al año. Resultados: Del grupo de 18 niños que completó el tratamiento homeopático, 14 no presentó episodio alguno de amigdalitis bacteriana aguda; del grupo de 15 niños que recibió placebo, 5 pacientes no presentaron amigdalitis. Esta diferencia fue estadísticamente significativa (p = 0,015). Ninguno de los pacientes presentó efectos secundarios. Conclusiones: El tratamiento homeopático fue efectivo en niños con amigdalitis recurrente, en comparación con el placebo; a 14 niños (78%) ya no se les indicó cirugía. El tratamiento homeopático no se asoció con eventos adversos.

The efficacy and safety of homeopathic treatment was investigated on children with recurrent tonsillitis justifying surgery. Methods: Prospective, randomized,double-blind clinical trial that included 40 children between ages of 3 to 7 years old;20 children were treated with homeopathic medication and 20 children with placebo. Follow up was 4 months per child. Assessment of results was clinical by means of a standard questionnaire and clinical examination on the first and last day of treatment.Recurrent tonsillitis was defined as 5 to 7 episodes of bacterial acute tonsillitis per year. Results: From the group of 18 children who completed homeopathic treatment, 14 did not present any episode of acute bacterial tonsillitis; from the group of 15 children whoreceived placebo 5 patients did not present tonsillitis; this difference was statistically significant (p= 0,015). None of the patient exhibited side effects. Conclusions: Homeopathic treatment was effective in children with recurrent tonsillitis compared to placebo, 14 children (78%) were no longer indicated surgery. Homeopathic treatment was not associated with adverse events.

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.
