    数字认知行为疗法的传播是治疗广大人群失眠的一种有希望的方法。目前的证据支持数字格式的有效性,但临床结果往往受到对照组选择和缺乏深入治疗措施的限制。本研究旨在研究数字认知行为疗法与自我监测应用相比的具体效果。符合失眠标准的参与者被随机分配(1:1)到8周的数字认知行为治疗或8周的数字睡眠监测(控制应用)。主要结果,失眠的严重程度,在基线评估,随机化后8周和16周。次要结果包括通过应用整合的睡眠日记和活动记录评估睡眠。拟合线性混合模型以评估组间差异。56名参与者(48名女性,平均年龄:M=45.55±13.70岁)随机接受数字认知行为治疗(n=29)或数字睡眠监测(n=27)。在随机化后8周和16周,大的治疗效果(d=0.87-1.08)表明数字认知行为治疗组失眠严重程度的显著降低(分别为-3.70和-2.97;p≤0.003),相对于数字睡眠监测。对于自我报告和活动记录得出的睡眠连续性变量,也发现了有利于数字认知行为疗法的治疗效果。表明在整个8周的干预期间睡眠有所改善。我们的研究加强了数字认知行为疗法在实现失眠患者临床改善中的作用。确认先前的发现并支持认知行为疗法的特定效果。
    Dissemination of digital cognitive behavioural therapy is a promising approach for treating insomnia in the broad population. Current evidence supports the effectiveness of the digital format, but clinical findings are often limited by the choice of control group and lack of in-depth therapeutic measures. This study was designed to investigate the specific effects of digital cognitive behavioural therapy in comparison to a self-monitoring application. Participants meeting criteria for insomnia were randomly allocated (1:1) to 8 weeks of digital cognitive behavioural therapy or 8 weeks of digital sleep monitoring (control application). The primary outcome, insomnia severity, was assessed at baseline, 8- and 16-weeks post-randomisation. Secondary outcomes included the assessment of sleep via application-integrated sleep diaries and actigraphy. Linear-mixed models were fitted to assess between-group differences. Fifty-six participants (48 females, mean age: M = 45.55 ± 13.70 years) were randomised to either digital cognitive behavioural therapy (n = 29) or digital sleep monitoring (n = 27). At 8- and 16-weeks post-randomisation, large treatment effects (d = 0.87-1.08) indicated robust reductions (-3.70 and -2.97, respectively; p ≤ 0.003) in insomnia severity in the digital cognitive behavioural therapy arm, relative to digital sleep monitoring. Treatment effects in favour of digital cognitive behavioural therapy were also found for self-reported and actigraphy-derived sleep continuity variables, indicating that sleep improved throughout the 8-week intervention period. Our study reinforces the role of digital cognitive behavioural therapy in achieving clinical improvements for patients with insomnia, affirming previous findings and supporting the specific effects of cognitive behavioural therapy.

    注意缺陷/多动症(ADHD)的诊断基于精神科医生对症状的临床评估,参考心理测试的结果。诊断多动症时,孩子在现实生活中的行为和功能是关键的组成部分。然而,临床医生的直接观察在实践中往往是不可行的。因此,这些信息通常是从主要护理人员或教师那里收集的,这可以引入主观因素。为了克服这些限制,我们开发了AttnKare-D,一种创新的数字诊断工具,可以使用人工智能在虚拟现实中分析儿童的行为数据。这项研究的目的是探讨AttnKare-D用于临床应用的实用性和安全性。
    本研究招募了21名年龄在6至12岁之间的儿童。其中,15名被诊断患有多动症的儿童,5个是正常对照组的一部分,1名儿童因撤回同意而被排除。心理评估,包括K-WISC,ConnersCPT,K-ARS,K-CBCL,对参与者及其主要护理人员进行了研究。儿童和青少年精神科医生根据全面的面对面评估和心理评估结果确认了多动症的诊断。参与者通过在VR环境中执行各种认知和行为任务来进行VR诊断评估。使用AI模型分析收集的数据,以评估ADHD诊断和症状的严重程度。
    AttnKare-D与儿童和青少年精神科医生的诊断相比,其诊断能力为0.893,在18.44的截止评分下显示0.8的灵敏度和1.0的特异性。AttnKare-D分数与父母和专家评定的K-ARS分数高度相关,尽管注意力不集中评分的相关性相对较低。
    这项研究的结果表明,AttnKare-D可以成为诊断儿童ADHD的有用工具。这种方法有可能克服当前诊断方法的局限性,提高ADHD诊断的准确性和客观性。本研究为进一步改进和研究整合VR和AI技术的诊断工具奠定了基础。对于未来的临床应用,有必要进行涉及足够数量参与者的临床试验,以确保可靠使用。
    UNASSIGNED: Diagnosis of Attention Deficit/Hyperactivity Disorder (ADHD) is based on clinical evaluation of symptoms by a psychiatrist, referencing results of psychological tests. When diagnosing ADHD, the child\'s behavior and functionality in real-life situations are critical components. However, direct observation by a clinician is often not feasible in practice. Therefore, such information is typically gathered from primary caregivers or teachers, which can introduce subjective elements. To overcome these limitations, we developed AttnKare-D, an innovative digital diagnostic tool that could analyze children\'s behavioral data in Virtual Reality using Artificial Intelligence. The purpose of this study was to explore the utility and safety of AttnKare-D for clinical application.
    UNASSIGNED: A total of 21 children aged between 6 and 12 years were recruited for this study. Among them, 15 were children diagnosed with ADHD, 5 were part of a normal control group, and 1 child was excluded due to withdrawal of consent. Psychological assessments, including K-WISC, Conners CPT, K-ARS, and K-CBCL, were conducted for participants and their primary caregivers. Diagnoses of ADHD were confirmed by child and adolescent psychiatrists based on comprehensive face-to-face evaluations and results of psychological assessments. Participants underwent VR diagnostic assessment by performing various cognitive and behavioral tasks in a VR environment. Collected data were analyzed using an AI model to assess ADHD diagnosis and the severity of symptoms.
    UNASSIGNED: AttnKare-D demonstrated diagnostic performance with an AUC of 0.893 when compared to diagnoses made by child and adolescent psychiatrist, showing a sensitivity of 0.8 and a specificity of 1.0 at a cut-off score of 18.44. AttnKare-D scores showed a high correlation with K-ARS scores rated by parents and experts, although the correlation was relatively low for inattention scores.
    UNASSIGNED: Results of this study suggest that AttnKare-D can be a useful tool for diagnosing ADHD in children. This approach has potential to overcome limitations of current diagnostic methods, enhancing the accuracy and objectivity of ADHD diagnoses. This study lays the groundwork for further improvement and research on diagnostic tools integrating VR and AI technologies. For future clinical applications, it is necessary to conduct clinical trials involving a sufficient number of participants to ensure reliable use.

    背景:使用基于虚拟现实(VR)的生物反馈(BF),一种相对较新的干预措施,是抑郁和焦虑症状的非药物治疗。然而,对基于VR的BF的研究缺乏且尚无定论。
    方法:从社区招募了131名成年人。在患者健康问卷-9(PHQ-9)上得分≥10或在恐慌症严重程度量表(PDSS)上得分≥9的参与者被纳入有抑郁或焦虑症状的组(DAS组),其他作为健康对照组(HC组)。来自DAS组的参与者被随机分配到基于VR或常规BF干预。3次(第0周、第2周和第4周)访问的所有个人,并完成了蒙哥马利-阿斯伯格抑郁量表(MADRS),状态特质焦虑量表(STAI),以及干预前后的视觉模拟量表(VAS),和PHQ-9在开始和最后访问。
    结果:分析共包括118名参与者(DAS/VR:40,DAS/BF:38,HC/VR:40)。三组之间的人口统计学变量没有显着差异。干预之后,DAS/VR和DAS/BF组MADRS显著下降,PHQ-9,STAI,和VAS评分与每组基线相比(p<0.005)。基于VR的BF与常规BF的效果之间没有显着差异。在接受基于VR的BF后,HC组的抑郁和焦虑指标也显着下降。
    结论:基于VR的BF可有效减少抑郁和焦虑症状,即使是HC组的阈值下抑郁和焦虑症状。
    BACKGROUND: The use of virtual reality (VR)-based biofeedback (BF), a relatively new intervention, is a non-pharmacological treatment of depressive and anxiety symptoms. However, studies on VR-based BF are lacking and inconclusive.
    METHODS: A total of 131 adults were recruited from the community. Participants who scored ≥10 on the Patient Health Questionnaire-9 (PHQ-9) or ≥9 on the Panic Disorder Severity Scale (PDSS) were included in the group with depressive or anxiety symptoms (DAS group), and others as the healthy control group (HC group). Participants from the DAS group were randomly assigned to VR-based or conventional BF intervention. All individuals visited at three times (weeks 0, 2, and 4), and completed the Montgomery-Asberg Depression Rating Scale (MADRS), the State-Trait Anxiety Inventory (STAI), and a visual analog scale (VAS) before and after the intervention, and PHQ-9 at the beginning and final visit.
    RESULTS: The analysis included a total of 118 participants (DAS/VR: 40, DAS/BF: 38, HC/VR: 40). There was no significant difference in demographic variables among the three groups. After the intervention, the DAS/VR group exhibited significant decreases in MADRS (70.0 %), PHQ-9 (64.1 %), STAI (29.5 %), and VAS (61.7 %) scores compared to the baseline (p <0.001). There were no significant differences between the effects of VR-based BF and conventional BF with a therapist. The HC group also showed significant decreases in the measures of depression and anxiety after receiving VR-based BF.
    CONCLUSIONS: VR-based BF was effective in reducing depressive and anxiety symptoms, even for subthreshold depression and anxiety symptoms in the HC group.

    目的:虽然国际指南提倡采用多方面的方法来治疗涉及体力活动的勃起功能障碍(ED),心理支持,和教育,结构化程序很少见。为了解决这个差距,开发了一种基于应用程序的疗法,提供系统的方法。这个随机的,一项单盲对照试验旨在评估基于app的治疗改善ED的有效性.
    方法:共有241例(49.74,标准差12.73年)ED(国际勃起功能指数[IIEF]-5<22)患者被随机分配到12周的应用基础治疗(治疗组[TG],n=122)或应用程序的等待列表,并继续其当前管理协议(控制组[CG],n=119)。包括长期服用ED药物的患者,但随后对开始新药物治疗的患者进行排除.共同终点是勃起功能(IIEF-5)从基线到12周的改善,疾病相关生活质量(QOL-Med-15),和患者激活(患者激活测量[PAM-13])。
    勃起功能(IIEF-5)在TG组中提高了4.5分,而在CG组中提高了0.2分(p<0.0001,95%置信区间[CI]3.4-5.0)。TG组的生活质量(QOL-Med)比CG组的-0.0分提高了20.5分(p<0.0001,95%CI19.2-26.0)。与CG组的0.6分相比,TG组的患者激活(PAM-13)提高了11.2分(p<0.0001,95%CI9.1-13.6)。磷酸二酯酶5型抑制剂的摄入对所有观察到的治疗效果没有影响。
    结论:基于App的ED患者治疗提供了显著的,有临床意义的改善。生活质量和患者激活也显著提高。该计划有可能改变ED治疗的临床实践。
    结果:一种治疗应用程序改善了勃起功能障碍男性的性功能和整体健康状况,带来更好的生活质量。
    OBJECTIVE: While international guidelines advocate for a multifaceted approach to treating erectile dysfunction (ED) involving physical activities, psychological support, and education, structured programs are infrequent. To address this gap, an app-based therapy was developed, offering a systematic approach. This randomized, single-blind controlled trial aimed to assess the effectiveness of an app-based therapeutic in improving ED.
    METHODS: A total of 241 patients (49.74, standard deviation 12.73 yr) with ED (International Index of Erectile Function [IIEF]-5 <22) were randomized to the 12-wk app-based therapy (treatment group [TG], n = 122) or a waiting list for the app with continuation of their current management protocol (control group [CG], n = 119). Patients on long-term medication for ED were included, but subsequent exclusion occurred for those starting new medication. Coprimary endpoints were improvements from baseline to 12 wk in erectile function (IIEF-5), disease-related quality of life (QOL-Med-15), and patient activation (Patient Activation Measure [PAM-13]).
    UNASSIGNED: Erectile function (IIEF-5) improved by 4.5 points in the TG versus 0.2 points in the CG (p < 0.0001, 95% confidence interval [CI] 3.4-5.0) group. Quality of life (QOL-Med) improved by 20.5 points in the TG versus -0.0 points in the CG (p < 0.0001, 95% CI 19.2-26.0) group. Patient activation (PAM-13) improved by 11.2 points in the TG versus 0.6 points in the CG (p < 0.0001, 95% CI 9.1-13.6) group. Phosphodiesterase type 5 inhibitor intake had no influence on all observed treatment effects.
    CONCLUSIONS: App-based therapy of patients with ED provided a significant, clinically meaningful improvement. Quality of life and patient activation were also enhanced significantly. This program has the potential to change clinical practice in the treatment of ED.
    RESULTS: A therapy app improved sexual function and overall well-being for men experiencing erectile dysfunction, leading to better quality of life.

    背景:新加坡,像亚洲其他地区一样,面临心理健康促进的持续挑战,包括围绕不健康和寻求治疗的耻辱,以及缺乏训练有素的心理健康人员。COVID-19大流行,这创造了精神卫生保健需求的激增,同时加速了数字健康解决方案的采用,揭示了在该地区快速扩展创新解决方案的新机会。
    目标:2020年6月,新加坡政府启动了思维。sg,一个匿名的数字心理健康资源网站,已经发展到包括超过500个策划的当地心理健康资源,一种经过临床验证的抑郁和焦虑自我评估工具,来自Wysa的人工智能(AI)聊天机器人,旨在提供数字治疗练习,以及为工作成年人量身定制的网站版本,称为工作中的思维。该平台的目标是使新加坡居民能够负责自己的心理健康,并能够通过无障碍数字解决方案的轻松便捷为周围的人提供基本支持。
    方法:通过GoogleAnalytics和自定义应用程序编程接口捕获的点击级数据分析来衡量网站使用情况。这反过来又驱动了基于开源平台TitaniumDatabase和Metabase的定制分析基础架构。独特,nonbounce(用户不立即从网站导航),已介入,并报告返回用户。
    结果:在发布后的2年中(2020年7月1日至2022年6月30日),该网站接待了>447,000名访客(约占目标人口300万的15%),62.02%(277,727/447,783)的人探索网站或参与资源(称为非弹跳访客);10.54%(29,271/277,727)的非弹跳访客返回。该平台上最受欢迎的功能是聊天机器人提供的基于对话的治疗练习和自我评估工具,25.54%(67,626/264,758)和11.69%(32,469/277,727)的非反弹访客使用了这些数据。在工作中,广泛参与的非反弹访客的比率(即,花费≥40秒勘探资源),一年内返回的人数分别为51.56%(22,474/43,588)和13.43%(5,853/43,588),分别,与30.9%(42,829/138,626)和9.97%(13,822/138,626)相比,分别,在通用的思维线上。sg网站在同一年。
    结论:该网站已达到预期的范围,并且访客数量增长强劲,这需要大量和持续的数字营销活动和战略外展伙伴关系。该网站小心翼翼地保持匿名性,限制分析的细节。总体采用的良好水平鼓励我们相信,轻度至中度的精神健康状况以及其背后的社会因素适合数字干预。而心态。sg主要在新加坡使用,我们相信本地定制的类似解决方案是广泛和全球适用的。
    BACKGROUND: Singapore, like the rest of Asia, faces persistent challenges to mental health promotion, including stigma around unwellness and seeking treatment and a lack of trained mental health personnel. The COVID-19 pandemic, which created a surge in mental health care needs and simultaneously accelerated the adoption of digital health solutions, revealed a new opportunity to quickly scale innovative solutions in the region.
    OBJECTIVE: In June 2020, the Singaporean government launched mindline.sg, an anonymous digital mental health resource website that has grown to include >500 curated local mental health resources, a clinically validated self-assessment tool for depression and anxiety, an artificial intelligence (AI) chatbot from Wysa designed to deliver digital therapeutic exercises, and a tailored version of the website for working adults called mindline at work. The goal of the platform is to empower Singapore residents to take charge of their own mental health and to be able to offer basic support to those around them through the ease and convenience of a barrier-free digital solution.
    METHODS: Website use is measured through click-level data analytics captured via Google Analytics and custom application programming interfaces, which in turn drive a customized analytics infrastructure based on the open-source platforms Titanium Database and Metabase. Unique, nonbounced (users that do not immediately navigate away from the site), engaged, and return users are reported.
    RESULTS: In the 2 years following launch (July 1, 2020, through June 30, 2022), the website received >447,000 visitors (approximately 15% of the target population of 3 million), 62.02% (277,727/447,783) of whom explored the site or engaged with resources (referred to as nonbounced visitors); 10.54% (29,271/277,727) of those nonbounced visitors returned. The most popular features on the platform were the dialogue-based therapeutic exercises delivered by the chatbot and the self-assessment tool, which were used by 25.54% (67,626/264,758) and 11.69% (32,469/277,727) of nonbounced visitors. On mindline at work, the rates of nonbounced visitors who engaged extensively (ie, spent ≥40 seconds exploring resources) and who returned were 51.56% (22,474/43,588) and 13.43% (5,853/43,588) over a year, respectively, compared to 30.9% (42,829/138,626) and 9.97% (13,822/138,626), respectively, on the generic mindline.sg site in the same year.
    CONCLUSIONS: The site has achieved desired reach and has seen a strong growth rate in the number of visitors, which required substantial and sustained digital marketing campaigns and strategic outreach partnerships. The site was careful to preserve anonymity, limiting the detail of analytics. The good levels of overall adoption encourage us to believe that mild to moderate mental health conditions and the social factors that underly them are amenable to digital interventions. While mindline.sg was primarily used in Singapore, we believe that similar solutions with local customization are widely and globally applicable.

    数字减肥干预为传统治疗提供了可行且具有成本效益的替代方案。然而,需要进一步的证据来确定两种方法的同等有效性。这项随机对照非劣效性试验旨在比较强化的当面减肥干预计划与Vitadio数字治疗的效果。100名肥胖并被诊断为2型糖尿病的患者,前驱糖尿病,纳入或胰岛素抵抗,并随机分配到两个治疗组之一.在6个月的时间里,对照组接受了五次专门治疗肥胖的医生的面对面咨询,营养师和/或营养护士,而干预组遵循基于多模式治疗方法的数字程序。评估并比较各组之间的体重减轻程度。此外,分析了数字干预组的身体成分和代谢参数的变化。研究结果表明,两种治疗方法对减轻体重的有效性相当。Vitadio的积极作用进一步通过干预组的身体成分和脂质代谢的有利变化以及改善的血糖控制得到证明。这些发现表明,Vitadio是帮助患者控制肥胖和预防糖尿病进展的有效工具。
    Digital weight loss interventions present a viable and cost-effective alternative to traditional therapy. However, further evidence is needed to establish the equal effectiveness of both approaches. This randomized controlled non-inferiority trial aimed to compare the effects of an intensive in-person weight loss intervention program with Vitadio digital therapy. One hundred patients with obesity and diagnosed with type 2 diabetes, prediabetes, or insulin resistance were enrolled and randomly assigned to one of the two treatment groups. Over a 6-month period, the control group received five in-person consultations with a physician who specialized in obesity treatment, a dietitian and/or a nutrition nurse, while the intervention group followed the digital program based on a multimodal therapeutic approach. The extent of weight loss was assessed and compared between the groups. Additionally, changes in body composition and metabolic parameters for the digital intervention group were analyzed. The study results demonstrated comparable effectiveness of both treatments for weight reduction. The positive effects of Vitadio were further evidenced by favorable changes in body composition and lipid metabolism and improved glycemic control in the intervention group. These findings suggest that Vitadio is an effective tool for assisting patients with managing obesity and preventing diabetes progression.

    背景:视野缺陷(VFD)代表中风后并发症,以视野中看不见的部分为特征。视觉感知学习(VPL)涉及盲区中重复的视觉训练,可有效恢复皮质盲的视野敏感度。这个当前的多中心,双盲,随机化,对照临床试验研究了基于VPL的数字疗法(NunapVision[NV])治疗卒中后VFD的有效性和安全性。
    方法:将患有VFD的中风门诊患者(中风发作后6个月)随机分为NV(有缺陷的现场训练)或Nunap视觉控制(NV-C,中央实地培训)小组。两种干预措施都提供了视觉感知训练,由方向组成,旋转,和深度歧视,通过虚拟现实头戴式显示设备每周5天,共12周。两组在基线和12周随访时使用汉弗莱视野(HVF)测试进行VFD评估。最终分析包括完成研究的人(NV,n=40;NV-C,n=35)。疗效测量包括改善的视觉面积(灵敏度≥6dB)和12周期间HVF评分的变化。
    结果:合规率高,NV和NV-C训练改善了缺陷半场(>72度2)和整个场(>108度2)的视觉区域,尽管组间没有显着差异,但仍有临床意义的改善。根据集团内部分析,在NV训练后(p=.03),但在NV-C训练后(p=.12),缺陷偏场的平均总偏差得分有所改善。
    结论:当前的试验表明,基于VPL的数字治疗可能会在卒中后VFD患者中引起有临床意义的视觉改善。然而,治疗效果的组间差异未发现,因为NV-C训练表现出与NV训练相当的意外改善,可能是由于学习迁移效应。
    BACKGROUND: Visual field defects (VFDs) represent a debilitating poststroke complication, characterized by unseen parts of the visual field. Visual perceptual learning (VPL), involving repetitive visual training in blind visual fields, may effectively restore visual field sensitivity in cortical blindness. This current multicenter, double-blind, randomized, controlled clinical trial investigated the efficacy and safety of VPL-based digital therapeutics (Nunap Vision [NV]) for treating poststroke VFDs.
    METHODS: Stroke outpatients with VFDs (>6 months after stroke onset) were randomized into NV (defective field training) or Nunap Vision-Control (NV-C, central field training) groups. Both interventions provided visual perceptual training, consisting of orientation, rotation, and depth discrimination, through a virtual reality head-mounted display device 5 days a week for 12 weeks. The two groups received VFD assessments using Humphrey visual field (HVF) tests at baseline and 12-week follow-up. The final analysis included those completed the study (NV, n = 40; NV-C, n = 35). Efficacy measures included improved visual area (sensitivity ≥6 dB) and changes in the HVF scores during the 12-week period.
    RESULTS: With a high compliance rate, NV and NV-C training improved the visual areas in the defective hemifield (>72 degrees2) and the whole field (>108 degrees2), which are clinically meaningful improvements despite no significant between-group differences. According to within-group analyses, mean total deviation scores in the defective hemifield improved after NV training (p = .03) but not after NV-C training (p = .12).
    CONCLUSIONS: The current trial suggests that VPL-based digital therapeutics may induce clinically meaningful visual improvements in patients with poststroke VFDs. Yet, between-group differences in therapeutic efficacy were not found as NV-C training exhibited unexpected improvement comparable to NV training, possibly due to learning transfer effects.
