Abstract Background Randomized controlled trials (RCTs), especially multicentric, with complex interventions are methodically challenging. Careful planning under everyday conditions in compliance with the relevant international quality standard (Good Clinical Practice [GCP] guideline) is crucial. Specific challenges exist for RCTs conducted in delivery rooms due to various factors that cannot be planned beforehand. Few published RCTs report challenges and problems in implementing complex interventions in maternity wards. In Germany as well as in other countries, midwives and obstetricians have frequently little experience as investigators in clinical trials. Methods The aim is to describe the key methodological and organizational challenges in conducting a multicenter study in maternity wards and the solution strategies applied to them. In particular, project-related and process-oriented challenges for hospital staff are considered. The exemplarily presented randomized controlled trial “BE-UP” investigates the effectiveness of an alternative design of a birthing room on the rate of vaginal births and women-specific outcomes. Results The results are presented in five sectors: 1) Selection of and support for cooperating hospitals: they are to be selected according to predefined criteria, and strategies to offer continuous support in trial implementation must be mapped out. 2) Establishing a process of requesting informed consent: a quality-assured process to inform pregnant women early on must be feasible and effective. 3) Individual digital real-time randomization: In addition to instructing maternity teams, appropriate measures for technical failure must be provided. 4) The standardized birthing room: The complex intervention is to be implemented according to the study protocol yet adapted to the prevailing conditions in the delivery rooms. 5) GCP-compliant documentation: midwives and obstetricians will be instructed in high-quality data collection, supported by external monitoring throughout the trial. Conclusion Since not all potential challenges can be anticipated in the planning of a trial, study teams need to be flexible and react promptly to any problems that threaten recruitment or the implementation of the complex intervention. Thought should be given to the perspectives of midwives and obstetricians as recruiters and how clinic-intern processes could be adapted to correspond with the trial’s requirements. Trial registration The BE-UP study was registered on 07/03/ 2018 in the German Register for Clinical Trials under Reference No. DRKS00012854 and can also be found on the International Clinical Trials Registry Platform (ICTRP) (see https://apps.who.int/trialsearch/Trial2.aspx?TrialID=DRKS0001285).

Abstract Background: RCTs with complex interventions are methodically challenging. Careful planning under everyday conditions in compliance with the relevant international quality standard (ICH-GCP guideline) is crucial. Specific challenges exist for RCTs conducted in delivery rooms due to various factors that cannot be planned beforehand, such as “peak hours” of births and a high work burden for midwives and obstetricians. Moreover, in Germany as well as in other countries, midwives and obstetricians have frequently little experience as investigators in clinical trials. Methods: The randomised controlled trial “BE-UP” tests the effectiveness of an alternative birthing room on the rate of vaginal births and woman-oriented outcomes. In the process of implementing the trial in 17 obstetrical units and in the endeavour to reach the calculated sample size of 3,800 women, the research team encountered a variety of unexpected challenges. The aim is to describe in greater detail the methodical and organisational challenges and to inform about the research team’s strategies to overcome them.Results:The results are presented in five sectors: 1) Selection of and support for cooperating hospitals: they are to be selected according to predefined criteria and strategies to offer continuous support in trial implementation must be mapped out.2) Establishing a process of requesting informed consent: a quality-assured process to inform pregnant women early on must be feasible and effective. 3) Individual, digital real time randomization: besides instructing the maternity teams appropriate measures for technical failure must be provided.4) The standardized birthing room: the complex intervention is to be implemented according to study protocol, yet adapted to the prevailing conditions in the delivery rooms.5) GCP-compliant documentation: midwives and obstetricians is to be instructed in high quality data collection, supported by external monitoring throughout the trial.Conclusion:Since not all potential challenges can be anticipated in the planning of a trial, study teams need to be flexible and react promptly to any problems that threaten recruitment or the implementation of the complex intervention.

Although machine perfusion is a hot topic today, we are just at the beginning of understanding the underlying mechanisms of protection. Recently, the first randomized controlled trial reported a significant reduction of ischemic cholangiopathies after transplantation of livers donated after circulatory death, provided the grafts were treated with an endischemic hypothermic oxygenated perfusion (HOPE). This approach has been known for more than fifty years, and was initially mainly used to preserve kidneys before implantation. Today there is an increasing interest in this and other dynamic preservation technologies and various centers have tested different approaches in clinical trials and cohort studies. Based on this, there is a need for uniform perfusion settings (perfusion route and duration), and the development of general guidelines regarding the duration of cold storage in context of the overall donor risk is also required to better compare various trial results. This article will highlight how cold perfusion protects organs mechanistically, and target such technical challenges with the perfusion setting. Finally, the options for viability testing during hypothermic perfusion will be discussed.

Abstract Background As the primary treatment for adhesive capsulitis, intensive and accurate home exercise is as important as physical therapy in hospitals. Augmented reality (AR)-based telerehabilitation has been implemented recently in various musculoskeletal conditions to increase patient compliance and enable patients to exercise with the correct posture. The objective of this study is to present a protocol for investigating the additive effect of interactive AR-based telerehabilitation in comparison with the usual care for patients with adhesive capsulitis. Methods This study presents the protocol of a prospective, multi-center, single-blinded, two-armed randomized controlled trial (RCT). One hundred patients with stage I or II adhesive capsulitis will be recruited at the physical medicine and rehabilitation clinic. Patients will be randomly divided into two groups with 1:1 allocation. The intervention group will receive 3 months of hospital-based physical therapy in conjunction with home-based telerehabilitation. The control group will receive 3 months of hospital-based physical therapy in conjunction with a home-based exercise described in a brochure provided by the hospital. The primary outcome will be the change in passive range of motion (ROM) of the affected shoulder joint from baseline to 12 weeks after baseline assessment. The secondary outcomes will be active ROM, pain measured with the numeric rating scale, shoulder pain and disability index, 36-Item Short Form Survey, EuroQoL-5D-5L, and Canadian Occupational Performance Measure. Discussion This will be the first RCT study protocol to investigate the effect of telerehabilitation in patients with adhesive capsulitis. The result of this RCT will determine whether AR-based telerehabilitation is more effective than a brochure-based home exercise program and will provide evidence of the usefulness of “telerehabilitation” using hardware (IoT) and software (monitoring platform) technologies to develop “digital therapeutics” for the future. Trial registration This trial was retrospectively registered at the Clinicaltrials.gov website on 20 March 2020, with the identifier NCT04316130.

Abstract Background As treatment of choice in promoting psychological flexibility, Acceptance and Commitment Therapy (ACT) was found to be effective in several conditions, and among different populations, including weight management in individuals with obesity. However, the mechanism of action of psychological flexibility is less known. The aim of the present study is, within the context of a brief ACT intervention for behavioral change and behavioral maintenance of a healthy lifestyle in a sample of inpatients with obesity, to explore the effect of each subcomponent of the psychological flexibility model on treatment processes and outcomes. Methods A randomized controlled trial will be conducted. Ninety Italian adult inpatients with obesity attending a rehabilitation program for weight loss will be randomly allocated into three experimental conditions targeting respectively each subcomponent of the psychological flexibility model: group Engage focused on values-oriented behaviors, group Openness focused on acceptance and cognitive defusion, and group Awareness focused on being present and aware of thoughts, feelings, and behaviors at every moment. Weight, BMI (kg/m2), the Psychological General Well-Being Inventory (PGWBI), the Outcome Questionnaire-45.2 (OQ-45.2), the Depression Anxiety and Stress Scale (DASS-21), the Difficulties in Emotion Regulation Scale (DERS), the Dutch Eating Behaviors Questionnaire (DEBQ), the Brief Values Inventory (BVI), the Committed Action Questionnaire (CAQ), the Italian-Cognitive Fusion Questionnaire (I-CFQ), the Five Facet Mindfulness Questionnaire (FFMQ), and the Acceptance and Action Questionnaire (AAQ-II) will be assessed at the beginning (time 0), at the end of psychological intervention (time 1), and after 3 (time 2) and 6 months (time 3) and 9 months (time 4) from discharge. During the following month after discharge, outpatients will be monitored in their adherence to a healthy lifestyle, using a wearable device. To assess the effectiveness of the intervention, mixed between-within 3 (conditions) × 4 (times) repeated measure ANOVAs will be conducted to examine changes from time 0 to time 1, 2, 3, and 4 in means of weight, BMI, and means of scores PGWBI, OQ-45.2, DASS, DERS, DEBQ, AAQ-II, BVI, CAQ, I-CFQ, and FFMQ, between three groups. Discussion This study will contribute to clarify the mechanism of action of each subcomponent of the psychological flexibility model and understand its impact on the promotion of a healthy lifestyle.

The Impact

Abstract Background Despite being considered preventable, ulcers due to pressure affect between 30 and 50% of patients at high and very high risk and susceptibility, especially those hospitalized under critical care. Despite a lack of evidence over the efficacy in prevention against ulcers due to pressure, hourly repositioning in critical care as an intervention is used with more or less frequency to alleviate pressure on patients’ tissues. This brings up the objective of our study, which is to evaluate the efficacy in prevention of ulcers due to pressure acquired during hospitalization, specifically regarding two frequency levels of repositioning or manual posture switching in adults hospitalized in different intensive care units in different Colombian hospitals. Methods A nurse-applied cluster randomized controlled trial of parallel groups (two branches), in which 22 eligible ICUs (each consisting of 150 patients), will be randomized to a high-frequency level repositioning intervention or to a conventional care (control group). Patients will be followed until their exit from each cluster. The primary result of this study is originated by regarding pressure ulcers using clusters (number of first ulcers per patient, at the early stage of progression, first one acquired after admission for 1000 days). The secondary results include evaluating the risk index on the patients’ level (Hazard ratio, 95% IC) and a description of repositioning complications. Two interim analyses will be performed through the course of this study. A statistical difference between the groups < 0.05 in the main outcome, the progression of ulcers due to pressure (best or worst outcome in the experimental group), will determine whether the study should be put to a halt/determine the termination of the study. Conclusion This study is innovative in its use of clusters to advance knowledge of the impact of repositioning as a prevention strategy against the appearance of ulcers caused by pressure in critical care patients. The resulting recommendations of this study can be used for future clinical practice guidelines in prevention and safety for patients at risk.

Second World

Background/aims Current research largely tends to ignore the drug-testing model that was developed in the “Second World” as an explicit alternative to the randomized controlled trial. This system can be described as “socialist pharmapolitics,” accounting for the specific features of state socialism that influenced the development and testing of experimental drugs. The clinical trials model employed in the “Second World” was heavily influenced by the Soviet Union, which was by far the most influential player in the socialist bloc during the Cold War. Based on extensive archival research, this article presents an empirical case of a late Soviet clinical trial as a pragmatic alternative to the randomized controlled trial model. It accounts for the divergences between the official model prescribed by the Soviet authorities and the messy realities of healthcare practice. It further outlines different factors that ultimately shaped how clinical trials were organized in Soviet institutions “on the ground.” Accordingly, this article presents a “real-life” history of “socialist pharmapolitics” and outlines the problems that this system faced in practice. Methods Archival research was conducted at the Russian State Archive of Scientific and Technical Documentation in Moscow. Archival files include scientific, technical, and registration documentation such as biochemical, pharmacological, and clinical descriptions of the experimental drug Meldonium, letters between various hospitals, research institutes and the Soviet regulatory body, as well as 26 reports of completed clinical trials. Manual content analysis was used for the interpretation of results. Results This article presents an empirical case of a late Soviet clinical trial as a pragmatic alternative to the randomized controlled trial model. It demonstrates some key differences from the randomized controlled trial model. This article also highlights some of the discrepancies between the model that was officially prescribed by the Soviet authorities and the realities of experimental drug testing in the Soviet Union in the late 1980s and early 1990s. In particular, it notes some elements of randomization, double-blinding, and the use of placebo that were present in Meldonium trials despite being formally denounced by Soviet bioethics. Conclusion The Soviet model for testing experimental drugs differed from the Western one substantially in a number of respects. This difference was not only proclaimed officially by the Soviet authorities, but was for the most part enforced in clinical trials in practice. At the same time, our research demonstrates that there were important differences between the official model and the clinical realities on the ground.

Abstract Background Many students in Germany do not meet recommended amounts of physical activity. In order to promote physical activity in students, web-based interventions are increasingly implemented. Yet, data on effectiveness of web-based interventions in university students is low. Our study aims at investigating a web-based intervention for students. The intervention is based on the Health Action Process Approach (HAPA), which discriminates between processes of intention formation (motivational processes) and processes of intention implementation (volitional processes). Primary outcome is change in physical activity; secondary outcomes are motivational and volitional variables as proposed by the HAPA as well as quality of life and depressive symptoms. Methods A two-armed randomized controlled trial (RCT) of parallel design is conducted. Participants are recruited via the internet platform StudiCare (www.studicare.com). After the baseline assessment (t1), participants are randomized to either intervention group (immediate access to web-based intervention) or control group (access only after follow-up assessment). Four weeks later, post-assessment (t2) is performed in both groups followed by a follow-up assessment (t3) 3 months later. Assessments take place online. Main outcome analyses will follow an intention-to-treat principle by including all randomized participants into the analyses. Outcomes will be analysed using a linear mixed model, assuming data are missing at random. The mixed model will include group, time, and the interaction of group and time as fixed effects and participant and university as random effect. Discussion This study is a high-quality RCT with three assessment points and intention-to-treat analysis meeting the state-of-the-art of effectiveness studies. Recruitment covers almost 20 universities in three countries, leading to high external validity. The results of this study will be of great relevance for student health campaigns, as they reflect the effectiveness of self-help interventions for young adults with regard to behaviour change as well as motivational and volitional determinants. From a lifespan perspective, it is important to help students find their way into regular physical activity. Trial registration The German clinical trials register (DRKS) DRKS00016889.

El objetivo de este artículo de revisión fue examinar y analizar la eficacia de los tipos de preparación psicológica empleados en los últimos ocho años para disminuir el estrés, la ansiedad y otras emociones de los pacientes ante un procedimiento quirúrgico. Método: Se realizó una revisión de literatura sobre la preparación psicológica en diferentes intervenciones quirúrgicas. Se realizó una búsqueda en la base de datos Medline y SCielo, utilizando las palabras clave: «psychological preparation for surgery» «psychological intervention and surgery» y se delimitó la búsqueda con las palabras «clinical trials» y «randomized controlled trial». Los criterios de inclusión fueron: ensayos clínicos controladosaleatorizados con resultados relacionados con la eficacia de la reducción del estrés, ansiedad y otras emociones. Se encontraron 17 ensayos clínicos que cumplieron los criterios de inclusión en la base de datos PubMed. En base de datos SciELO solo se encontraron dos estudios. Los datos nos muestran que las tendencias en preparación psicológica se han enfocado más a los procedimientos como la cirugía electiva, cirugía pediátrica, procedimientos con agujas, cirugías de corazón, cirugías para el cáncer y para la cirugía bariátrica. Sin embargo, la perspectiva de estas investigaciones tal vez pudiera centrarse en las enfermedades crónica degenerativas y con más estudios mejorados metodológicamente
