STROKE
The University Hospital of Umeå is the coordinating centre where the Chief Investigator (the first author) and a trial management group (TMG) work. The coordinating centre oversees the fiscal management of the study, ethics approvals, subcontracts with other participating clinics and other financial and oversight responsibilities. The TMG consists of two research nurses, two medical engineers, two RCT coordinators and the Chief Investigator. The TMG provides daily support and troubleshooting to the local participating clinics and has a brief meeting once a week to discuss actual issues.A trial steering committee (TSC) is composed of a national collaboration among four universities and regions in Sweden. The TSC includes an independent chairperson (the last author) and multiple independent members (coauthors), including statisticians, persons with biomedical engineering degrees, rehabilitation and trial experience and patient representatives (nonauthors). TSC responsibilities include clinical setup of the study, ongoing management, study promotion and planning for the interpretation and dissemination of results. TSC meetings were held monthly during the trial planning phase. TSC meetings will take place annually at a minimum to monitor study progress and provide public, clinical information during the active phase. Moreover, professional advice to TMG members will be provided in a timely manner via e-mail or telephone when needed. The TSC will be responsible for reviewing issues and any concerns warranting modification or termination of the study.An advisory board consisting of three professors within the stroke field will provide supervision and feedback on the project annually to the TSC. Together with TSC, this board will ensure that the interpretation of findings is applicable to current practice.

ADVERSE EFFECTS, STROKE, RECRUITMENT, STROKE
Stroke is a leading cause of disability among adults worldwide, with a heavy burden for patients and their families as well as society [To meet these challenges, Rehabkompassen® was recently created and developed as a novel and unique digital follow-up tool to identify and graphically visualize a panoramic view of stroke patients’ heterogeneous rehabilitation needs based on 6 well-validated and reliable PROMs [This two-arm pragmatic multisite study will be able to provide unequivocal results of the eventual effectiveness of the Rehabkompassen tool since both the intervention and control are used in normal practice. Moreover, this trial provides substantial flexibility concerning the adaptation of the Rehabkompassen tool into everyday clinical practice, such as stroke units, early support discharge units and stroke rehabilitation units, in the post-acute continuum of care after stroke in Sweden. A multicentre study also means extra attention should be given to ensure the minimization of the differences and variations among clinics. This is why we will collect baseline data concerning usual care and provide the study information and a training program on the usage of Rehabkompassen® and REDCap prior to patient recruitment. In addition, much information about implementation will be collected from medical practitioners in the participating clinics in the proposed study. Together with the high generalizability of the pragmatic trial [Despite the potential usefulness of the tool, there are various practical and operational issues to consider in this study. We are certainly aware of the major challenge of recruiting more than 1000 patients, which is required for the power analysis. Our pilot study demonstrated a recruitment rate of 28% with a retention rate of 86% at the 12-month follow-up without any severe adverse effects during the heavy pandemic period [We are also aware of the challenge of running such a large multicentre study, especially concerning data collection and management, which is why a separate data management plan has been established and kept at Umeå University. Another issue is technical obstacles for the participants, who are often elderly since the mean age of stroke patients is 73 years old [This study will provide strong evidence on the effectiveness and cost-effectiveness of a novel digital follow-up tool, Rehabkompassen®, in persons discharged from acute care settings after stroke. In addition to improving the tool to be more user -riendly, we envisage finding a cost-effective solution to carry out standard follow-up visits and to facilitate patient-tailored rehabilitation in persons with stroke in current clinical practice. This tool has the potential to improve everyday life for many stroke patients and to reduce the health, social and economic burdens after stroke for patients and their families as well as society. The outcomes of this trial will inform clinical practice and health care policy on the role of the digital follow-up tool Rehabkompassen® in the post-acute continuum of care after stroke.

depression
There is increasing evidence that depression can be prevented; however, universal approaches have had limited success. Appropriate targeting of interventions to at-risk populations has been shown to have potential, but how to selectively determine at-risk individuals remains unclear. Workplace stress is a risk factor for depression and a target for intervention, but few interventions exist to prevent depression among workers at risk due to heightened stress.

Overview
RECRUITMENT
Participants were recruited using social media advertisements that ran for 27 days from March 2020 to April 2020. Separate recruitment via industry partners had to be abandoned owing to the COVID-19–related economic restrictions. Individuals who clicked a link on the advertisements were taken to a brief study description page on the research institute website and the After consenting, the participants were administered the SISQ as a screening measure. This item measures current stress on a 5-point Likert scale, ranging from 1 (“not at all”) to 5 (“very much”) and has been validated for screening stress levels in a working population [Eligible trial participants created a study account (using email and password) and completed the web-based baseline assessment within their account. Randomization occurred immediately after completion of the assessment. The allocation of participants to the intervention or control condition was concealed using automated procedures integrated into the trial management software. Computer-generated block randomization was used, with a block size of 4, to ensure that equal numbers of participants were assigned to each condition.The intervention group was provided with links to download Participants completed web-based follow-up assessments at 1 month, 3 months, and 6 months after baseline assessment.

App Use
On average, users completed 7.68 (SD 9.26) unique challenges. Although a large portion of the intervention group (518/1053, 49.19%) completed ≤3 challenges, with rates continuing to decline over the full course of the 30-day challenge, 4.84% (51/1053) of the users completed the content in its entirety.Total app use (challenge plus toolbox activities) was notably higher. On average, users completed 10.83 (SD 12.61; range 0-104) activities, with 9.5% (100/1053) completing >30 activities. This indicates that users chose to repeat some challenge activities via the toolbox section.

App Feedback
App feedback was received from 468 users: 179 (38.2%) low engagers, 162 (34.6%) medium engagers, and 93 (27.1%) high engagers. The app was well received by respondents, with 81% (379/468) claiming that it had at least moderately improved their mental fitness and only 10.7% (50/468) claiming that they felt no improvement. The majority of the respondents (396/468, 84.6%) claimed that they understood the app content either very well or completely, whereas 91% (426/468) stated that they would recommend the app. Most users found the app design to be at least somewhat interesting or engaging (419/468, 89.5%) and the content at least somewhat interesting or engaging (432/468, 92.3%). Additionally, 77.4% (362/468) found it very or extremely easy to use. Most respondents (321/468, 68.6%) gave the app a 4- or 5-star overall rating.Participants rated cognitive-focused activities (eg, thought challenging) as the most useful (147/466, 31.5%), followed by mindfulness (135/466, 29%), and behavioral activation or goal setting (112/466, 24%). Psychoeducational videos (39/466, 8.4%) and general coping skills activities (eg, exercise, sleep, and socializing; 33/466, 7.1%) had the lowest usefulness ratings. Of those who provided feedback, 43.5% (203/467) claimed to be continuing to use the app, whereas the most common reasons for stopping app use were lack of time (101/467, 21.6%) and lost interest (63/467, 13.5%). A common theme among those who did not complete the intervention was forgetting to use the app.

Principal Findings and Comparison With Prior Work
depression, depressive symptoms
This study evaluated the efficacy of a smartphone app to prevent depression in workers reporting elevated levels of stress. The app did not reduce the incidence of depression, defined as a “case,” but users showed small comparative reductions in depressive symptoms at 1- and 6-month follow-ups. Program adherence was relatively low, with users completing, on average, a quarter of the intervention content. This was potentially impacted by the timing of the study, which occurred during the onset of the COVID-19 crisis in Australia, which may have affected users’ level of commitment. However, when adherence was high, the outcomes showed significant positive changes.A prior uncontrolled pilot study of The ability of the The promising moderation effects of engagement and the significant impact on work performance provide further support for the real-world utility of the app and support findings elsewhere of the small functional impacts of mobile health interventions [
PMC10485707
Limitations
SECONDARY
The findings of this trial are hampered by low rates of app engagement. The issue of engagement is crucial to digital interventions broadly, presenting a barrier to optimal implementation and necessitating further research. Previous work in this area has highlighted a number of elements that might enhance engagement with workplace digital interventions [A further study limitation was the high dropout rate. Although app feedback was generally positive, it was only received from those completing the postintervention assessment, so it cannot be considered representative of the entire sample. The intervention components seen as most useful were the core CBT elements (thought challenging and behavioral activation), along with mindfulness, whereas the content that focused on improving coping skills through lifestyle change (eg, sleep, alcohol use, relationships, and exercise) was less well received. Encouragingly, this suggests that the formal elements of CBT are viewed by app users as critical even within a prevention framework. An additional limitation was that although the work performance metric was derived from an existing measure and has been used in prior studies, it has not been psychometrically validated; therefore, some caution is recommended in interpreting this secondary outcome.Finally, although the focus was an “at-risk” stressed population, there were high rates of self-reported previous mental ill health, which suggests that the observed evidence of a preventative effect may in fact be—for many users—prevention of relapse. However, as recruiting a sample of working adults with elevated levels of stress with no previously reported mental health concerns would be both impractical and lack real work validity, this is not entirely a shortcoming, and it does not diminish the potential utility of the app, but rather highlights where the interest in such an intervention is likely to reside. Similarly, as with any trial of this kind, there is the potential for a self-selection bias, and thus, the findings may not be representative of all workers. Nevertheless, these tools represent important sources of support for these motivated workers.

1. Introduction
neurological deficits, rupture, Stroke, necrosis
HYPOXIC, STROKE, NECROSIS
Stroke is a lesion caused by blockage or rupture of a blood vessel in the brain, resulting in ischemic and hypoxic necrosis of brain tissue, corresponding neurological deficits and consequent symptoms in the dominant area.Thumb-to-finger is one of the basic movements that the hand can complete, and clinically rehabilitate through the opponent’s thumb-to-finger movement to restore certain hand functions. The thumb-to-finger process is actually the pinching process, during which the muscles involved are mainly the first interosseous dorsal muscle and the short thumb extensors, which move in concert to complete the above action. FLES is the application of low-frequency electrical currents to traditional acupuncture points, both to improve the internal state of nerve cells through electrical currents and to regulate the balance of yin and yang, unblock meridians, and promote the flow of qi and blood through acupoint stimulation.

Thumb-to-finger dysfunction is a difficult point in the treatment of stroke sequelae, affecting upper limb function and grasping ability. In this study, thumb-to-finger dysfunction was mainly due to decreased activation of the extensor and flexor muscles of the fingersThe results showed that the 2 therapies improved the pinching function between the thumb and 2 fingers, the flexion exercise of the interphalangeal joint extension exercise of the thumb, the neurological function defect after stroke, the grading of hand motor function, the degree of upper limb spasm, the muscle strength of the hand, muscle tone, the coordination function between each other and the muscle strength classification of patients after stroke, and the efficacy of the low-frequency group was significantly better than that of the EA group (This study explores the clinical effect of LFES therapy in the treatment of this disease, but there are some shortcomings and prospects. The main problems are: failure to compare and follow up the efficacy of cycles, and the inability to determine the optimal treatment cycle and long-term efficacy; The mechanism was not explored, only clinical efficacy was proved, and the mechanism of action and evaluation of safety and scope of adaptation could not be explained; Trials were conducted only in a single center, with small sample sizes, possible selection bias and regional variation, affecting our confidence in the results. It is recommended to improve the following in the future: regular follow-up of patients to clarify long-term clinical efficacy; Increase the comparison of clinical efficacy of cycles and clarify the optimal treatment cycle; Conduct animal experiments to prove scientific and normative nature, and conduct mechanism discussions; Adopt multi-center, large-sample clinical trials to improve rigor and objectivity; Studies were conducted in different regions and populations to analyze applicability and effectiveness, and to explore differentiation and individualization.

Background
ATRIAL FIBRILLATION (AF)
Radiofrequency catheter ablation (RFCA) for patients with atrial fibrillation (AF) can generate considerable physical and psychological discomfort under conscious sedation. App-based mindfulness meditation combined with an electroencephalography (EEG)-based brain-computer interface (BCI) shows promise as effective and accessible adjuncts in medical practice.

ADVERSE EVENTS
This single-center pilot randomized controlled trial involved 84 eligible patients with AF scheduled for RFCA, who were randomized 1:1 to the intervention and control groups. Both groups received a standardized RFCA procedure and a conscious sedative regimen. Patients in the control group were administered conventional care, while those in the intervention group received BCI-based app–delivered mindfulness meditation from a research nurse. The primary outcomes were the changes in the numeric rating scale, State Anxiety Inventory, and Brief Fatigue Inventory scores. Secondary outcomes were the differences in hemodynamic parameters (heart rate, blood pressure, and peripheral oxygen saturation), adverse events, patient-reported pain, and the doses of sedative drugs used in ablation.

ADVERSE EVENTS, ATRIAL FIBRILLATION (AF), COMPLICATIONS, CARDIAC ARRHYTHMIA
Atrial fibrillation (AF) is recognized as the most common cardiac arrhythmia worldwide, with an estimated prevalence of 2%-4% in adults [Considering the longer general anesthesia preparation time, higher economic costs, and potential complications, conscious sedation is used for RFCA at most centers in China [Mindfulness meditation originates from Buddhist teachings and refers to a category of techniques used to pay attention to the present moment and accept all that arises without judgment [A brain-computer interface (BCI) is defined as a technology for establishing external information communication and control pathways between the human brain and computers or other electronic devices [This study aimed to determine the effects of a BCI-based mindfulness meditation app on RFCA for patients with AF. The primary hypothesis was that the intervention group would experience significant improvements in perceived pain, anxiety, and fatigue compared to the control group. We also hypothesized that the intervention might decrease the use of sedative drugs and the incidence of adverse events.

Study Design
This was a single-center, 2-arm, parallel-group, prospective, pilot randomized controlled trial. Patients were randomized 1:1 to the intervention and control groups using a computer-generated randomization list. Due to the nature of the study design, neither program implementers nor patients could be blinded to the intervention. However, the investigators performing the outcome assessments and data analysis were blinded to the group allocation.

Overview
cognitive complaints, pain
MALIGNANT TUMORS, SYSTEMIC DISEASE
Patients were eligible for the study if they were (1) diagnosed with AF, (2) at least 18 years old, (3) undergoing their initial RFCA procedure, and (4) willing to participate in the study. Patients were excluded if they had (1) severe systemic diseases such as malignant tumors, (2) a history of mental illness and cognitive complaints, and (3) difficulty understanding the questionnaire and the study aims. They were also excluded if they experienced drastic changes in their condition during RFCA.Sample size calculations were conducted using PASS 2021 (NCSS LLC) software and based on previous studies [All patients underwent a standardized RFCA procedure for AF with a 3D mapping system (CARTO 3, Biosense Webster) and were provided with standardized information about the study and the potential benefits and risks of the interventions. Both groups received the same sedative regimen during RFCA, which was adjusted by the interventional physician based on the patient's response to the medication and reported pain levels. The regimen included a single dose of parecoxib (40 mg), fentanyl (1 mcg/kg/hour), and dexmedetomidine as necessary, with dosing adjustments made in accordance with standard pain management procedures at our institution. The fentanyl maintenance infusion rate ranged from 0 to 2 mcg/kg/hour, while the dexmedetomidine maintenance infusion rate ranged from 0 to 1 mcg/kg/hour.

Intervention Group
Patients in the intervention group received mindfulness meditation guidance delivered through a Chinese-language interface and voice app (Focus Zen, version 2.1.1) along with a BCI-based headband. A mobile phone and a Samsung tablet device with the preinstalled app were prepared in the cardiac catheterization laboratory. Before ablation, study staff briefly introduced the method and meaning of mindfulness meditation to help patients understand the intervention content. Mindfulness meditation represents a practice of awareness in which the person gradually and purposefully focuses on the present without judgement to achieve a state of deep relaxation [Screenshots of the study app. (A) Device connection, (B) background sound setting, and (C) mindfulness meditation course).

Control Group
pain
The control group received routine care for their ablation procedure and was informed about the procedure of ablation and characteristics of impending pain in ablation, as in the intervention group. Psychological and supportive care were provided in accordance with the patients' needs. However, patients in the control group wore the headband device without using the earphones and did not receive mindfulness meditation guidance provided by the app.

Outcome Measurements
anxiety, fatigue, pain
Both the intervention and control groups were administered 2 surveys, one 30 minutes before ablation and one within 30 minutes after ablation, to assess pain intensity, fatigue, and anxiety using specific paper questionnaires. Demographic information and characteristics of participants were collected at baseline. The study staff recorded patients' hemodynamic parameters (heart rate, blood pressure, and peripheral oxygen saturation [SpOThe primary outcomes were pain and anxiety levels during ablation and fatigue severity after ablation.

Principal Findings
fatigue, anxiety, pain
The purpose of this study was to evaluate the effectiveness of a novel BCI-based mindfulness meditation app for patients with AF to improve their physical and psychological status in RFCA. The selected app provides EEG feedback for mindfulness meditation, which may help patients relax and reduce unpleasant experiences without interfering with the ablation process. The key findings showed significantly lower pain, anxiety, and fatigue scores in the intervention group than among those receiving conventional care. No significant differences were found in the mean heart rate, blood pressure, or SpOMobile health, via wireless technologies such as smartphone apps and wearable devices, is currently used for patients with AF mostly for screening, management, and rehabilitation [It is well known that RFCA for AF can be accompanied by considerable pain and anxiety when conscious sedation is used, which, however, has potential side effects [When patients experience physical and mental discomfort in RFCA, the levels of catecholamines, adrenocorticotropic hormone, prolactin, cortisol, and prostaglandins in their blood may increase [

Strengths and Limitations
A strength of this study is that it is the first randomized controlled trial, to our knowledge, to explore the effectiveness of a mindfulness meditation app together with a BCI-based wearable device among patients with AF during RFCA, which adds to the evidence base in the areas of meditation and mobile health. This study was designed rigorously. We provided the same care protocol and implemented the use of wearable devices for both groups, and recorded the time, energy, and temperature of ablation to ensure comparable conditions. In addition, this study was performed in a pragmatic setting and no maximum age for participation was stated, which adds to the generalizability of our findings.This study also has some limitations. First, it was not a double-blind trial. Neither study staff nor patients were blinded to the intervention due to the nature of the study design. However, the data analysts were masked to group allocation. Additionally, meditation practice is a long-term process. Even with the help of apps and wearable devices, it takes time to master meditation techniques to reach a meditative state faster. At least one preoperative practice session could be added to the protocol for the intervention group; however, this might affect the comparability of the baseline measures. Lastly, this is a single-center study, thus limiting the generalizability of our findings.

ADVERSE EVENTS
In conclusion, this study shows that BCI-based app–delivered mindfulness meditation significantly relieved pain, anxiety, fatigue, and may reduce the doses of sedative medication used during RFCA for AF. Although no significant differences in hemodynamic parameters and the incidence of adverse events were observed, there was a decrease in the incidence of adverse events in the intervention group. Smartphone apps and wearable devices could serve as feasible and promising adjuncts to improve patients with AF’s experience in RFCA.This research was supported by the National Natural Science Foundation of China (72074124), Young Scholars Fostering Fund of the First Affiliated Hospital of Nanjing Medical University (PY2022002), and the Clinical Ability Improvement Project of the First Affiliated Hospital of Nanjing Medical University (JSPH-NC-2021-16).Authors' Contributions: YH and ZB contributed to the development and administration of the project.

METHODS:
ADVERSE EVENTS, EPITHELIAL TUMORS, SECONDARY
This multicenter, open-label, randomized controlled trial involved 227 patients with gastric and rectal epithelial tumors in whom ESD was indicated. Patients in whom the source of blood oozing was difficult to identify with waterjet washing during the procedure and required hemostasis with hemostatic forceps were randomly assigned to the TDM-621 and control groups. The TDM-621 group (in which hemostasis was achieved with TDM-621, followed by coagulation hemostasis with hemostatic forceps, as needed) was compared with the control group (in which hemostasis was achieved with hemostatic forceps). The primary end point was the mean number of coagulations with hemostatic forceps, determined by a blinded independent review committee. The secondary end points were the rate of achievement of hemostasis with only TDM-621, the dosage of TDM-621, and adverse events in the TDM-621 group.
