ABSTRACT

ABSTRACT BACKGROUND: Although the concept of an "ongoing study" seems self-explanatory, it is difficult to determine whether a trial is underway. OBJECTIVE: To analyze the definitions of "ongoing clinical trial" across different clinical trial registries, methodological guidelines, and other sources. DESIGN AND SETTING: This meta-research study was conducted at the Universidade Federal de São Paulo (UNIFESP), Brazil. METHODS: We performed a cross-sectional analysis of relevant clinical trial registry databases, methodological guidelines for conducting systematic reviews, and other sources that would define or regulate clinical trials. RESULTS: We identified various heterogeneous definitions used by eligible sources at both the start and end of a clinical trial. The starting criteria used were as follows: when the team is planning the protocol, when permission is given to conduct the study, or when the first participant is enrolled. Some sources used the time at which the last outcome data was collected as a criterion to determine the end of the trial. The International Committee of Medical Journal Editors stated that a study is still "ongoing" during the analysis process. Several sources use a vague definition or present no clear criteria for defining the start or end of a study. CONCLUSION: The concept of "ongoing clinical trials" lacks a transparent and homogeneous definition across relevant sources. A consensus on this concept is important to facilitate the evaluation of available evidence and conduct research synthesis. Further efforts are necessary to determine the best definition for the start and end of a clinical trial.

ABSTRACT

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.

ABSTRACT

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).

ABSTRACT

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.

ABSTRACT

Trials within cohorts (TwiCs) are design methods derived from randomized controlled trials (RCTS). They have been widely used in chronic disease areas such as tumors and cardiovascular diseases. The basis of the TwiCs design is a prospective cohort of specific diseases. When RCTS need to be implemented, some patients meeting the inclusion and exclusion criteria are randomly sampled from the cohort to receive "trial interventions", while the remaining patients in the cohort who meet the inclusion and exclusion criteria continue to receive conventional treatment as control groups. By comparing the efficacy differences between the intervention measures of the trial group and the control group, the efficacy of intervention measures was evaluated. Within the cohort, the same process could be repeated to carry out multiple RCTS, so as to evaluate different intervention measures or compare the efficacy of different doses or timing of interventions. Compared with classical RCTS, TwiCs make it easier to recruit patients from the cohort and have higher external validity, providing a new research paradigm for improving the efficiency and applicability of RCTS in clinical practice. However, TwiCs may also face the challenge of poor compliance of patients in the cohort. Researchers need to take effective measures to control these patients in the design and operation of TwiCs. This article focused on the methodological key points during the implementation of TwiCs, including multi-stage informed consent (patients are informed of consent at three stages: entering the cohort, entering the trial group, and after the trial), randomization procedures (only random sampling of patients from the cohort to receive "trial interventions"), sample size calculation, and statistical analysis methods. The article also compared the differences between TwiCs and traditional RCTS and illustrated TwiCs research design and analysis with examples, so as to provide new research ideas and methods for clinical researchers.

ABSTRACT

It is believed that kidney deficiency is the fundamental pathogenesis while liver constraint and spleen deficiency, and disharmony of chong (thorough vessel, 冲脉)and ren (conception vessel, 任脉) is the key pathogenesis of infertility patients who adopted controlled ovarian hyperstimulation of in vitro fertilization-embryo transfer (IVF-ET) programme. Therefore, the method of tonifying the kidneys dominantly and treating the liver and spleen simultaneously is proposed, and Chinese herbal medicine is suggested to be used in adjuvant treatment of staged IVF-ET controlled ovrian hyperstimulation. In the regulation stage, modified Liuwei Dihuang Pill (六味地黄丸) can be used to tonify kidney and supplement essence, fortify spleen and nourish liver; in the ovulation promotion stage, modified Wenjing Decoction (温经汤) should be used to warm kidney and assist yang, dispel stasis and nourish blood; in the pre-transplantation endothelial preparation stage, modified Shenling Baizhu Powder (参苓白术散) is suggested to fortify spleen and replenish qi, invigorate blood and resolve stasis; after the transplantation stage, modified Shoutai Pill (寿胎丸) or Taiyuan Decoction (胎元饮) can be taken to fortify spleen and tonify kidney, benefit qi and nourish blood.

ABSTRACT

ObjectiveTo systematically collect, analyze, and evaluate the randomized controlled trials (RCT) of Chinese patent medicine combined with western medicine in the treatment of hypertension, map the evidence, and provide reference for the future clinical research and formulation of guidelines and policies. MethodThe relevant articles were retrieved from China Biology Medicine disc, China National Knowledge Infrastructure (CNKI), VIP, Wanfang Data, PubMed, Embase, and Cochrane Library with the time interval from inception to December 31, 2022. The RCT of Chinese patent medicines combined with western medicine in the treatment of hypertension were included. The research characteristics and methodological quality were analyzed and evaluated. ResultA total of 330 RCTs of treating hypertension with Chinese patent medicines combined with Western medicine were included in this study, all of which were published in Chinese. These RCTs involved 88 Chinese patent medicines and 37 788 patients, and 46% of RCT had the sample size ≥100 patients. Eighty-seven percent of RCT showed the study period within 3 months. All the interventions in the RCTs were Chinese patent medicine + western medicine vs western medicine. Among the evaluation indicators, blood pressure, response rate, TCM syndrome score, endothelial cell function, and safety were mainly concerned. In terms of methodological quality, most articles did not mention the generation of random sequences, allocation concealment, or blinding method. The blinding evaluation of outcomes showed low risks of bias, and there was insufficient information to judge whether there was selective bias or other bias. ConclusionThere were many Chinese patent medicines used in combination with western medicine in the treatment of hypertension, and they were mainly taken orally. The existing RCT had problems such as small sample size, unclear clinical value positioning, imperfect design failing to reflect the value of Chinese patent medicines, unreasonable measurement indicators, and non-standard measurement methods. Future research should solve the above problems, improve the research quality, value, and authenticity, and enhance the reliability and extension of evidence.

ABSTRACT

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.

ABSTRACT

Introducción: La medición de la presión arterial es uno de los procedimientos más realizados en la práctica clínica. La presente revisión narrativa pretende sintetizar los aspectos relevantes que rodearon la definición de la hipertensión arterial, el recorrido histórico del tratamiento de esta y el aporte de los estudios a la disminución de la mortalidad por enfermedad cardiovascular en el tiempo. Metodología: Revisión narrativa de la historia de la hipertensión arterial, desde el reconocimiento de la presión arterial alta como un factor asociado al riesgo cardiovascular y la evolución histórica del tratamiento hasta los hallazgos significativos del estudio SPRINT, publicado en 2015. Resultados: Hasta hace aproximadamente 50 años la hipertensión arterial era conocida como una patología esencial, es decir, esta condición no siempre fue considerada como una enfermedad. El descubrimiento de la presión sanguínea ha sido atribuido a Stephen Hales, poeta, orador y sacerdote nacido en Inglaterra. La primera medición de la presión sanguínea e incidentalmente de la presión del pulso la realizó en 1733 en animales. Se describe el origen de la presión arterial, la hipertensión arterial, el camino recorrido para el reconocimiento de esta condición como enfermedad y posteriormente su tratamiento, hasta llegar al estudio SPRINT en 2015, el cual fue contundente en demostrar el beneficio de reducir la cifra de presión arterial sistólica objetivo en una población no diabética. Conclusión: Los resultados de esta revisión narrativa exponen cómo el reconocimiento de la presión arterial alta como un factor de riesgo cardiovascular permitió el avance en la investigación científica para determinar el tratamiento y las cifras de presión arterial que favorecen la reducción de la mortalidad y morbilidad por esta causa.


Background: Blood pressure measurement is one of the most performed procedures in clinical practice. This narrative review aims to expose the relevant aspects surrounding the definition of arterial hypertension, the historical path of its treatment, and the contribution of studies to the decrease in mortality due to cardiovascular disease over time. Methodology: Narrative review of the history of arterial hypertension from recognizing high blood pressure as a factor associated with cardiovascular risk to the historical evolution of treatment up to the SPRINT study published in 2015. Results: Until about 50 years ago, arterial hypertension was known as an essential pathology; this condition was not always considered a disease. The discovery of blood pressure has been attributed to Stephen Hales, a poet, orator and priest born in England. The first measurement of blood pressure and incidentally pulse pressure was made in 1733 in animals. The origin of blood pressure, arterial hypertension, and the path travelled for recognizing this condition as a disease and later its treatment until reaching the SPRINT study in 2015, which demonstrated the benefit of reducing the target systolic blood pressure figure in a non-diabetic population. Conclusion: This narrative review demonstrates that the recognition of high blood pressure as a cardiovascular risk factor allowed progress in scientific research to determine the treatment and blood pressure figures that favor the reduction of mortality and morbidity from this cause.

ABSTRACT

Objective. The present study examined the effect of an interventional program underpinned by the Health Belief Model (HBM) on nurses' awareness, attitude, and performance in preventing nosocomialinfections.Methods. This randomized controlled trial study was performed on 60 clinical nurses in lar, Iran. Nurses were selected using the simple random sampling method and assigned to two experimental (n=30) and control (n=30) groups. Data collection tool included the valid and reliable questionnaire was developed by Soleimani et al. The research intervention consisted of five 90-min sessions based on the health belief model in preventing hospital infection for experimental group. Before the intervention, immediately and two months after the intervention, the two groups completed the questionnaire. The control group received no intervention. Results. Data analysis showed that the differences between the two groups was statistically significant immediately and two months after the intervention (p<0.05). In experimental group the changes in the mean score of knowledge, attitude and performance of nurses before, immediately and two months after the intervention were significant (p<0.05), but in the control group, only the changes in the mean score of performance were significant (p<0.05). Conclusion. The results showed that the HBM-based intervention is effective in promoting nurses' knowledge, attitude, and performance in preventing nosocomialinfections. hence, periodical and in-service HBM-based training programs on preventing nosocomialinfections are recommended to be held for nurses.

ABSTRACT

Las campañas de prevención y promoción de salud, así como los avances en las medidas terapéuticas destinadas a los pacientes neurocríticos, han logrado reducir la incidencia de pacientes con injuria encefálica aguda (IEA) que evolucionan a la muerte encefálica (ME). Sin embargo, en la mayoría de los países de América Latina, los órganos perfusibles aptos para trasplante (TX) provienen de donantes fallecidos en ME. La donación en asistolia (DA), y en particular la donación en asistolia controlada (DAC), constituye una opción aceptada y válida para la obtención de órganos que contribuiría a la disminución de las listas de espera para trasplante. Durante el proceso de DAC, se aplican conceptos con fuerte impronta bioética cuya aplicación resulta fundamental en el momento de la toma de decisiones. El presente artículo tiene el objetivo de analizar dichos conceptos con la finalidad de otorgar herramientas válidas al equipo asistencial para aquellos procesos en los que existe deliberación moral, como ocurre en la donación de órganos en asistolia controlada, considerada parte integral de los cuidados al final de la vida.


Campaigns for health prevention and promotion, along with advancements in therapeutic measures for neurocritical patients, have succeeded in reducing the incidence of patients with acute brain injury (ABI) progressing to brain death (BD). However, in most Latin American countries, suitable perfusable organs for transplantation (TX) come from deceased donors in brain death (BD). Donation after circulatory death (DCD), particularly controlled donation after circulatory death (cDCD), represents an accepted and valid option for organ procurement that would contribute to reducing transplant waiting lists. During the cDCD process, strong bioethical principles are applied, and their implementation is crucial when making decisions. The purpose of this article is to analyze these concepts, aiming to provide valid tools to the healthcare team for processes involving moral deliberation, such as controlled circulatory death organ donation, considered an integral part of end-of-life care.


As campanhas de prevenção e promoção da saúde, bem como os avanços na medidas terapêuticas voltadas para pacientes neurocríticos conseguiram reduzir a incidência de pacientes com lesão cerebral aguda que evoluem para morte encefálica (ME). No entanto, na maioria dos países latino-americanos, os órgãos que podem ser perfundidos adequados para transplante (TX) vêm de doadores falecidos em ME. A doação em assistolia e em particular a doação em assistolia controlada (DAC),é uma opção aceita e válida para a obtenção de órgãos, o que contribuiria para a redução das listas de espera para transplantes. Durante o processo DAC, são aplicados conceitos com forte cunho bioético, que são fundamentais na o momento da tomada de decisão. Este artigo tem como objetivo analisar esses conceitos, com o objetivo de oferecer ferramentas válidas à equipe de saúde, para os processos em que há deliberação moral como ocorre na doação de órgãos em assistolia controlada considerada parte integrante dos cuidados de fim de vida.

ABSTRACT

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


RESUMO O objetivo deste estudo será apresentar o protocolo de um ensaio clínico randomizado em cluster a ser realizado por meio do projeto TeleUTI - Qualificação da Assistência em Terapia Intensiva por Telemedicina. O estudo consistirá em um ensaio clínico randomizado por cluster, open label, em unidades de terapia intensiva pediátricas, com proporção de alocação de 1:1, com o intuito de comparar o grupo de intervenção (apoio da telemedicina para os pacientes internados na unidade de terapia intensiva pediátrica) com um grupo controle (cuidados habituais da unidade de terapia intensiva pediátrica). O estudo se propõe a selecionar 16 unidades de terapia intensiva pediátricas, incluindo 100 participantes por local, com o total de 1.600 participantes. O grupo intervenção receberá telerounds de segunda-feira a sexta-feira e terá à disposição especialistas e atividades de educação continuada. O desfecho primário a ser avaliado será o tempo de permanência nas unidades de terapia intensiva pediátricas, definido pela diferença entre a data de alta do participante com a data de admissão na unidade de terapia intensiva. Os desfechos secundários serão: taxa de mortalidade; dias livres de ventilação mecânica, dias de uso de antibióticos, dias de uso de drogas vasoativas e dias de uso de sedoanalgesia. Este estudo será conduzido em conformidade com a resolução 466/12 do Conselho Nacional de Saúde, com aprovação pelo Comitê de Ética em Pesquisa das instituições hospitalares envolvidas. O trabalho tem o potencial de reproduzir estudos sobre Telemedicina em cuidados intensivos, podendo trazer contribuições importantes ao atendimento em unidades de terapia intensiva no Brasil e em outras realidades. Se a Telemedicina mostrar resultados clínicos assistenciais positivos em relação ao tratamento convencional, mais pacientes pediátricos poderão ser beneficiados.

ABSTRACT

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.

ABSTRACT

ABSTRACT Objectives: To provide an overview of low-intensity extracorporeal shockwave therapy (LIEST) for erectile dysfunction (ED), pointing out which concepts are already consolidated and which paths we still need to advance. Materials and Methods: We performed a narrative review of the literature on the role of shockwave therapies in erectile dysfunction, selecting publications in PUBMED, including only relevant clinical trials, systematic reviews and meta-analyses. Results: We found 11 studies (7 clinical trials, 3 systematic review and 1 meta-analysis) that evaluated the use of LIEST for the treatment of erectile dysfunction. One clinical trial evaluated the applicability in Peyronie's Disease and one other clinical trial evaluated the applicability after radical prostatectomy. Conclusions: The literature presents little scientific evidence but suggests good results with the use of LIEST for ED. Despite a real optimism since it is a treatment modality capable of acting on the pathophysiology of ED, we must remain cautious, until a larger volume of higher quality studies allows us to establish which patient profile, type of energy and application protocol will achieve clinically satisfactory results.

ABSTRACT

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)

ABSTRACT

ABSTRACT BACKGROUND AND OBJECTIVES: Patient-controlled analgesia (PCA) is effective in controlling pain, but has numerous associated risks, such as: hypotension, respiratory depression, seizures and excessive sedation. The promotion of patient safety aims to reduce the risk of unnecessary health injuries and, therefore, it is important to analyze the failures and risk factors present throughout the process proactively. Therefore, the aim of this study was to map the available evidence on the risks of adverse events associated with the PCA technique and patient safety actions. CONTENTS: This is a scoping review conducted according to the JBI methodology, whose research question was based on the PCC strategy. The source of information is open and the search occurred in three stages. The databases used were: Medline/Pubmed; LILACS; CINAHL/ EBSCOhost; CENTRAL; Portal Capes; SCOPUS; Web of Science; Google academic; Brazilian Digital Library of Theses and Dissertations; Portal NICE; and Portal ISMP. The search strategy was divided into 3 stages: the first occurred in Medline and Cinahl to identify articles and index terms on the topic; the second used all keywords in all included databases; the third consisted of tracking searches in the reference lists of the included studies. The search resulted in 1,164 studies, of which 83 were selected based on the inclusion criteria: addressing the risks associated with the PCA pump or safety measures, hospital context, without restriction as to the type of study, language, and year. The studies are distributed in categories: previous diseases, profile of indications, types of opioids, types of pump and infusion, adverse effects, incidents without harm, stages of risk, and safety measures. CONCLUSION: This study made it possible to identify the risks of adverse events associated with the use of PCA in different stages and safety actions, demonstrating that when performed with appropriate patients, trained staff, safe devices, and correct prescription it provides a statistically significant improvement in pain relief, safely with advantages that conventional analgesia does not have.


RESUMO JUSTIFICATIVA E OBJETIVOS: A analgesia controlada pelo paciente (ACP) é eficaz no controle da dor, porém apresenta inúmeros riscos associados, tais como: hipotensão arterial, depressão respiratória, convulsões e sedação excessiva. A promoção da segurança do paciente visa reduzir o risco de lesões desnecessárias à saúde e, para tanto, é importante analisar as falhas e fatores de risco presentes em todo o processo de forma proativa. Portanto, o objetivo deste estudo foi mapear as evidências disponíveis sobre os riscos de eventos adversos associados à técnica de ACP e a ações de segurança do paciente. CONTEÚDO: Trata-se de uma revisão de escopo realizada segundo a metodologia Joanna Briggs Institute para Scoping Reviews, cuja questão de pesquisa se baseou na estratégia PCC (P: população; C: conceito; C: contexto). As bases de dados utilizadas foram: Medline/Pubmed, LILACS, CINAHL/EBSCOhost, CENTRAL, Portal Capes, SCOPUS, Web of Science, Google acadêmico, Biblioteca Digital Brasileira de Teses e Dissertações, Portal NICE, Portal ISMP. A estratégia de busca foi dividida em 3 etapas: a primeira ocorreu na Medline e Cinahl para identificar artigos e termos de índice sobre o tema; a segunda utilizou todas as palavras-chaves em todas as bases de dados incluídas; a terceira consistiu no rastreamento de pesquisas nas listas de referências dos estudos incluídos. A busca resultou em 1.164 estudos, dos quais 83 foram selecionados com base nos seguintes critérios de inclusão: abordagem dos riscos associados à bomba de ACP ou a medidas de segurança, contexto hospitalar, sem restrição quanto ao tipo de estudo, idioma e ano. Os achados sintetizados estão distribuídos em categorias: doenças prévias, perfil das indicações, tipos de opioides, tipos de bomba e de infusão, efeitos adversos, incidentes sem lesões, estágios de risco e medidas de segurança. CONCLUSÃO: Este estudo possibilitou identificar os riscos de eventos adversos associados ao uso da ACP em diferentes estágios e ações de segurança, demonstrando que quando realizada com pacientes adequados, com equipe treinada, dispositivos seguros e prescrição correta, fornece uma melhora estatisticamente significativa no alívio da dor, de forma segura e com vantagens que a analgesia convencional não possui.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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
