    BACKGROUND: HIV-infected children have a higher risk of presenting infections, including the hepatitis A virus (HAV). The inactivated HAV vaccine is immunogenic in immunocompetent hosts; however, there are insufficient studies on the duration of seroprotection in HIV-infected children.
    METHODS: An analytical cohort study was conducted. HIV-1-infected children who received the inactivated HAV vaccine (2 doses) were included. Blood samples were taken for antibody measurement, the first one 28 days after the second dose and another 7 years after the vaccination schedule. Information on viral load, immunological category, weight, height, and response to antiretroviral treatment from diagnosis to the last assessment was obtained.
    RESULTS: 19 patients were included, with a mean age of 12.6 years (SD ± 2.29). 58% were male. 80% of the patients presented protective immunoglobulin G antibodies against HAV 7-year post-vaccination. The antibody concentration was found to be between 13 and 80 mIU/mL (median of 80 mIU/mL). 52% showed some degree of immunosuppression. There was no statistically significant relationship between the presence of seroprotection and viral load, treatment failure, immunological category, and malnutrition. Twelve patients presented with antiretroviral treatment failure, and in 33% of them, the antibodies did not offer satisfactory seroprotection.
    CONCLUSIONS: 7-year post-vaccination, 80% of HIV-infected children maintain seroprotection titers against HAV.
    UNASSIGNED: Los niños infectados por el virus de la inmunodeficiencia humana (VIH) tienen mayor riesgo de presentar infecciones, incluyendo hepatitis por virus A (VHA). La vacuna inactivada contra el VHA es inmunógena en el huésped inmunocompetente. No hay estudios suficientes sobre el tiempo de seroprotección en niños infectados por el VIH.
    UNASSIGNED: Estudio de cohorte, analítico. Se incluyeron niños con infección por VIH-1 que recibieron la vacuna inactivada contra el VHA (dos dosis). Se les tomaron muestras sanguíneas para medición de anticuerpos, una 28 días después de la segunda dosis y otra 7 años después del esquema de vacunación. Se obtuvo información de carga viral, categoría inmunológica, peso y talla, y respuesta al tratamiento antirretroviral desde el diagnóstico hasta la última valoración.
    RESULTS: Se incluyeron 19 pacientes con una edad media de 12.6 años (± 2.29). El 58% fueron del sexo masculino. El 80% de los pacientes presentaron anticuerpos immunoglobulin G (IgG) contra el VHA protectores a los 7 años de la vacunación. La concentración de anticuerpos se encontró entre 13 y 80 mUI/ml (mediana: 80 mUI/ml). El 52% mostraron algún grado de inmunosupresión. No existe relación estadísticamente significativa entre la presencia de seroprotección y la carga viral, la falla al tratamiento, la categoría inmunológica ni la desnutrición. Doce pacientes presentaron falla al tratamiento antirretroviral; en el 33% de ellos los anticuerpos no ofrecían seroprotección satisfactoria.
    CONCLUSIONS: A 7 años posvacunación, el 80% de los niños con VIH mantienen títulos de seroprotección frente al VHA.

    目标:医院和临床医生越来越多地通过与基于价值的购买相关的财务激励措施,根据护理质量获得报销。以患者为中心的护理,通过患者体验调查来衡量,是许多质量激励计划的关键组成部分。我们假设等待时间等操作方面是急诊科(ED)患者体验的重要因素。本文的目的是确定(1)ED等待时间与患者体验之间的关联,以及(2)患者评论是否显示出等待时间的意识。
    方法:这是一项从2019年1月1日至2020年12月31日的横断面观察研究,涉及区域医疗保健系统内的16个ED。患者和手术数据是通过内部来源获得的次要数据,并与我们的数据分析团队的主要患者经验数据合并。因变量是(1)以分钟为单位的ED等待时间与患者体验评级之间的关联,以及(2)以分钟为单位的等待时间与包括术语等待(是/否)的患者评论之间的关联。患者在0至10量表上对他们的“推荐可能性(LTR)ED”进行了评分(类别:“启动子”=9-10,“中性”=7-8或“牵引器”=0-6)。我们的综合经验评级,或净启动子得分(NPS),对于每个不同的等待时间(四舍五入到最近的分钟),通过以下公式计算:NPS=100*(#启动子-#差分法)/(#启动子+#中性+#差分法)。患者年龄、性别和分诊敏锐度的独立变量,被列为潜在的混杂因素。作为等待30分钟的函数,我们对评级类别进行了混合效应多变量有序逻辑回归。我们还对评论等待30分钟的患者百分比进行了逻辑回归。针对16个ED位点之间的聚类调整标准误差。
    结果:共有50833名独特参与者完成了体验调查,代表8.1%的反应率。在这些受访者中,28.1%包括评论,10.9%使用术语“等待”。“等待30分钟与LTR类别关联的赔率比为0.83[0.81,0.84]。随着等待时间的增加,评论等待的可能性增加1.49[1.46,1.53]。我们展示了这两种关系的与政策相关的气泡图可视化。
    结论:随着等待时间的增加,患者获得积极的患者体验评分的可能性较小,这反映在他们的评论中。改善导致ED等待时间的因素对于满足医疗保健系统的质量计划至关重要。
    OBJECTIVE: Hospitals and clinicians increasingly are reimbursed based on quality of care through financial incentives tied to value-based purchasing. Patient-centered care, measured through patient experience surveys, is a key component of many quality incentive programs. We hypothesize that operational aspects such as wait times are an important element of emergency department (ED) patient experience. The objectives of this paper are to determine (1) the association between ED wait times and patient experience and (2) whether patient comments show awareness of wait times.
    METHODS: This is a cross-sectional observational study from January 1, 2019, to December 31, 2020, across 16 EDs within a regional health care system. Patient and operations data were obtained as secondary data through internal sources and merged with primary patient experience data from our data analytics team. Dependent variables are (1) the association between ED wait times in minutes and patient experience ratings and (2) the association between wait times in minutes and patient comments including the term wait (yes/no). Patients rated their \"likelihood to recommend (LTR) an ED\" on a 0 to 10 scale (categories: \"Promoter\" = 9-10, \"Neutral\" = 7-8, or \"Detractor\" = 0-6). Our aggregate experience rating, or Net Promoter Score (NPS), is calculated by the following formula for each distinct wait time (rounded to the nearest minute): NPS = 100* (# promoters - # detractors)/(# promoters + # neutrals + # detractors). Independent variables for patient age and gender and triage acuity, were included as potential confounders. We performed a mixed-effect multivariate ordinal logistic regression for the rating category as a function of 30 minutes waited. We also performed a logistic regression for the percentage of patients commenting on the wait as a function of 30 minutes waited. Standard errors are adjusted for clustering between the 16 ED sites.
    RESULTS: A total of 50 833 unique participants completed an experience survey, representing a response rate of 8.1%. Of these respondents, 28.1% included comments, with 10.9% using the term \"wait.\" The odds ratio for association of a 30-minute wait with LTR category is 0.83 [0.81, 0.84]. As wait times increase, the odds of commenting on the wait increase by 1.49 [1.46, 1.53]. We show policy-relevant bubble plot visualizations of these two relationships.
    CONCLUSIONS: Patients were less likely to give a positive patient experience rating as wait times increased, and this was reflected in their comments. Improving on the factors contributing to ED wait times is essential to meeting health care systems\' quality initiatives.

    我们旨在确定食管胃十二指肠镜检查检查上消化道(UGI)癌症的质量指标。回顾性收集了2012年8月至2022年1月的43,526次连续健康检查的数据。该研究最终分析了12位内窥镜医师进行的42,387次检查,这些检查进行了1000多次检查,包括所有检测到的癌症。这些内窥镜医师根据他们在检查的第一年中正常发现食道胃十二指肠镜检查的平均检查时间分为快/慢组。或基于内窥镜图像数量的小/大组,分别。分析UGI癌症检出率与检查时间或图像数量之间的关联,使用5分钟或50张图像作为截止值。整体的检出率(8咽、39食道,69例胃癌),慢,小,大集团占0.17%,0.32%,0.21%,和0.31%,分别。在多变量分析中,快速组或小组的内镜医师发现整体UGI癌的可能性较小(OR:0.596,95%CI:0.373-0.952,P=.030;OR:0.652,95%CI:0.434-0.979,P=.039).此外,在2年内重复内窥镜检查具有较高的整体癌症检出率,与2年后重复筛查相比。在一个子分析中,发现胃癌的检出率与胃图像数量<35之间存在显着负相关(OR:0.305,95%CI:0.189-0.492,P=.000)。咽喉癌和食管癌的检出率与食管图像数量<11之间也呈负相关趋势(OR:0.395,95%CI:0.156-1.001,P=0.050)。图像的最佳数量和筛查2年间隔被认为是检测UGI癌症的有用质量指标。这项研究还表明,总共有50张照片,或35张胃部图像适用于检测UGI癌症,或者胃癌,在筛查内窥镜检查期间。
    We aimed to identify quality indicator for esophagogastroduodenoscopy for detecting upper gastrointestinal (UGI) cancer. Data from 43,526 consecutive health checkups from August 2012 to January 2022 were retrospectively collected. The study ultimately analyzed 42,387 examinations by 12 endoscopists who performed more than 1000 examinations, including all cancers detected. These endoscopists were classified either into fast/slow group based on their mean examination time for a normal finding of esophagogastroduodenoscopy during their first year of the examination, or small/large group based on number of endoscopic images, respectively. The association between UGI cancer detection rate and examination time or the number of images was analyzed, using 5 minutes or 50 images as cutoff values. The detection rate of overall (8 pharyngeal, 39 esophageal, 69 gastric) cancers in the fast, slow, small, and large groups were 0.17%, 0.32%, 0.21%, and 0.31%, respectively. On multivariable analysis, endoscopists in the fast group or the small group were less likely to detect overall UGI cancer (OR: 0.596, 95% CI: 0.373-0.952, P = .030; OR: 0.652, 95% CI: 0.434-0.979, P = .039). Additionally, repeated endoscopy within 2 years had a higher overall cancer detection rate, compared with repeated screening after 2 years. In a sub-analysis, a significant negative relationship was found between the detection rate of gastric cancer and the number of gastric images < 35 (OR: 0.305, 95% CI: 0.189-0.492, P = .000). There was also a negative correlation trend between the detection rate of pharyngeal and esophageal cancers and the number of esophageal images < 11 (OR: 0.395, 95% CI: 0.156-1.001, P = .050). The optimal number of images and screening 2-year interval are considered useful quality indicators for detecting UGI cancer. This study also suggests that a total of 50 images, or 35 images of the stomach are suitable for detecting UGI cancer, or gastric cancer, during screening endoscopy.

    目的:报告了B型壁内血肿(IMH)单中心经验中最佳药物治疗(BMT)和介入治疗(INT)的结果。
    方法:从2015年2月至2021年2月,共纳入195例B型IMH连续患者。主要终点是死亡率,次要终点包括临床和影像学结局.临床结果为主动脉相关性死亡,逆行A型主动脉夹层,支架移植物引起的新的进入撕裂,内漏,和重新干预。通过最新的随访计算机断层扫描血管造影评估成像结果,包括主动脉破裂,主动脉夹层,主动脉瘤,主动脉直径快速增长,新出现或扩大的穿透性主动脉溃疡或溃疡样突起(ULP)和主动脉壁厚度增加。使用Kaplan-Meier曲线评估不同处理之间的关联。
    结果:在入选患者中,115收到BMT,80人获得了智力。BMT组和INT组的早期(1.7%vs2.5%;P=1.00)和中期全因死亡(8.3%vs5.2%;P=.42)没有显着差异。然而,接受INT的患者存在手术相关并发症的风险,如支架移植物引起的新的进入撕裂和内漏.INT组与ULP的风险大大降低有关,包括新开发的ULP(4.3%对26.9%;P<0.05),ULP增大(6.4%vs31.3%;P<.05),高危ULP的比例较低(10.9%vs45.6%;P<.05)。虽然两组间IMH消退的发生率无显著差异,与接受BMT治疗的患者相比,接受INT治疗的患者降主动脉的最大直径更大.
    结论:根据我们有限的经验,接受BMT或INT治疗的B型IMH患者的中期临床结局相似.接受INT的患者可能会降低ULP的风险,但手术相关事件的风险较高,BMT患者应密切监测ULP进展.
    OBJECTIVE: The outcomes of the best medical treatment (BMT) and intervention treatment (INT) in a single-center experience were reported in type B intramural hematoma (IMH).
    METHODS: From February 2015 to February 2021, a total of 195 consecutive patients with type B IMH were enrolled in the study. The primary end point was mortality, and the secondary end points included clinical and imaging outcomes. The clinical outcomes were aortic-related death, retrograde type A aortic dissection, stent graft-induced new entry tear, endoleak, and reintervention. The imaging outcome was evaluated through the latest follow-up computed tomography angiography, which included aortic rupture, aortic dissection, aortic aneurysm, rapid growth of aortic diameter, newly developed or enlarged penetrating aortic ulcer or ulcer-like projection (ULP) and increased aortic wall thickness. Kaplan-Meier curves were used to assess the association between different treatments.
    RESULTS: Among the enrolled patients, 115 received BMT, and 80 received INT. There was no significant difference in early (1.7% vs 2.5%; P = 1.00) and midterm all-cause death (8.3% vs 5.2%; P = .42) between the BMT and INT groups. However, patients who underwent INT were at risk of procedure-related complications such as stent graft-induced new entry tear and endoleaks. The INT group was associated with a profound decrease in the risk of ULP, including newly developed ULP (4.3% vs 26.9%; P < .05), ULP enlargement (6.4% vs 31.3%; P < .05), and a lower proportion of high-risk ULP (10.9% vs 45.6%; P < .05). Although there was no significant difference in the incidence of IMH regression between the two groups, the maximum diameter of the descending aorta in patients receiving INT was larger compared with those treated with BMT.
    CONCLUSIONS: Based on our limited experience, patients with type B IMH treated with BMT or INT shared similar midterm clinical outcome. Patients who underwent INT may have a decreased risk of ULPs, but a higher risk of procedure-related events and patients on BMT should be closely monitored for ULP progression.

    背景:痴呆症的护理是一个动态的多维过程。为了全面了解痴呆症患者的非正式护理(PLWD),评估非正式护理人员的生活质量(QoL)至关重要。
    目的:评估护理接受者关系类型是否可以预测PLWD非正式护理人员在两年期间的QoL变化。
    方法:这是对纵向数据的二次分析。数据来自国家健康与老龄化趋势研究(NHATS)和国家护理研究(NSOC)的两波相关数据(2015:NHATSR5&NSOCII;2017:NHATSR7&NSOCIII)。照顾者分为配偶,成年子女,\"其他\"看护者和\"多个\"看护者。通过负面情绪负担(NEB)评估QoL,积极的情感利益和社会压力(SS)。广义估计方程模型用于检查不同类型关系的护理人员QoL结果随时间的变化。
    结果:关于,包括与601PLWD相关的882名护理人员。在调整护理人员的社会人口统计学后,“其他”照顾者的NEB和SS风险低于配偶照顾者(OR=0.34,P=0.003,95CI[0.17,0.70];OR=0.37,P=0.019,95CI0.16,0.85],分别),和PLWD的痴呆状态不会改变这些显著性(OR=0.33,P=0.003,95CI[0.16,0.68];OR=0.31,P=0.005,95CI[0.14,0.71],分别)。
    结论:研究表明,随着时间的推移,配偶照顾者面临更高的NEB和SS风险,强调迫切需要为PLWD的非正式护理人员提供无障碍和有效的支持,尤其是照顾配偶的人.
    BACKGROUND: Dementia caregiving is a dynamic and multidimensional process. To gain a comprehensive understanding of informal caregiving for people living with dementia (PLWD), it is pivotal to assess the quality of life (QoL) of informal caregivers.
    OBJECTIVE: To evaluate whether the care-recipient relationship type predicts changes in the QoL of informal caregivers of PLWD over a two-year period.
    METHODS: This was a secondary analysis of longitudinal data. The data were drawn from two waves of linked data from the National Health and Aging Trends Study (NHATS) and the National Study of Caregiving (NSOC) (2015: NHATS R5 & NSOC II; 2017: NHATS R7 & NSOC III). Caregivers were categorized into spousal, adult-child, \"other\" caregiver and \"multiple\" caregivers. QoL was assessed through negative emotional burden (NEB), positive emotional benefits and social strain (SS). Generalized estimating equation modelling was used to examine changes in caregivers\' QoL outcomes across types of relationship over time.
    RESULTS: About, 882 caregivers were included who linked to 601 PLWD. After adjusting caregivers\' socio-demographics, \"other\" caregivers had lower risk of NEB and SS than spousal caregivers (OR = 0.34, P = 0.003, 95%CI [0.17, 0.70]; OR = 0.37, P = 0.019, 95%CI 0.16, 0.85], respectively), and PLWD\'s dementia status would not change these significance (OR = 0.33, P = 0.003, 95%CI [0.16, 0.68]; OR = 0.31, P = 0.005, 95%CI [0.14, 0.71], respectively).
    CONCLUSIONS: The study demonstrates that spousal caregivers face a higher risk of NEB and SS over time, underscoring the pressing need to offer accessible and effective support for informal caregivers of PLWD, especially those caring for their spouses.

    背景:表观遗传衰老是最有前途的衰老生物标志物之一,可能是身体功能下降的有用标志物,超过实际年龄。这项研究调查了560名年龄≥70岁的澳大利亚人(50.7%的女性)中,表观遗传年龄加速度(AA)是否与7年以上的虚弱评分变化以及7年的事故虚弱和持续的日常生活活动(ADL)残疾风险有关。
    方法:七个AA指数,包括GrimAge,GrimAge2,FitAge和DunedinPACE,从基线外周血DNA甲基化进行估计。使用67项赤字积累脆弱指数(FI)和Fried表型(Fried)评估脆弱。持续性ADL残疾被定义为至少6个月内丧失执行一个或多个基础ADL的能力。适当时使用线性混合模型和Cox比例风险回归模型。
    结果:加速GrimAge,基线时的GrimAge2、FitAge和DunedinPACE与每年增加的FI评分相关(调整后的β范围从0.0015到0.0021,P<0.05),和加速GrimAge和GrimAge2与事件FI定义的脆弱风险增加相关(分别为1.43和1.39,P<0.05)。女性DunedinPACE与FI评分变化之间的关联更强(调整后的β0.0029,P0.001比男性(调整后的β0.0002,P0.81)。DunedinPACE,但不是其他AA措施,也与Fried评分恶化相关(调整后β0.0175,P0.04)。未观察到与持续性ADL残疾的关联。
    结论:晚年表观遗传AA与每年增加的衰弱评分和发生FI定义的衰弱的风险相关。
    BACKGROUND: Epigenetic ageing is among the most promising ageing biomarkers and may be a useful marker of physical function decline, beyond chronological age. This study investigated whether epigenetic age acceleration (AA) is associated with the change in frailty scores over 7 years and the 7-year risk of incident frailty and persistent Activities of Daily Living (ADL) disability among 560 Australians (50.7% females) aged ≥70 years.
    METHODS: Seven AA indices, including GrimAge, GrimAge2, FitAge and DunedinPACE, were estimated from baseline peripheral-blood DNA-methylation. Frailty was assessed using both the 67-item deficit-accumulation frailty index (FI) and Fried phenotype (Fried). Persistent ADL disability was defined as loss of ability to perform one or more basic ADLs for at least 6 months. Linear mixed models and Cox proportional-hazard regression models were used as appropriate.
    RESULTS: Accelerated GrimAge, GrimAge2, FitAge and DunedinPACE at baseline were associated with increasing FI scores per year (adjusted-Beta ranged from 0.0015 to 0.0021, P < 0.05), and accelerated GrimAge and GrimAge2 were associated with an increased risk of incident FI-defined frailty (adjusted-HRs 1.43 and 1.39, respectively, P < 0.05). The association between DunedinPACE and the change in FI scores was stronger in females (adjusted-Beta 0.0029, P 0.001 than in males (adjusted-Beta 0.0002, P 0.81). DunedinPACE, but not the other AA measures, was also associated with worsening Fried scores (adjusted-Beta 0.0175, P 0.04). No associations were observed with persistent ADL disability.
    CONCLUSIONS: Epigenetic AA in later life is associated with increasing frailty scores per year and the risk of incident FI-defined frailty.

    目标:关于生物领域经历持续时间的研究很少。这项初步研究使用了ChoaKokSui大师的手敏化的体验式学习实践,以确定在手之间体验生物场感觉的持续时间,并找到学习风格偏好与生物场感觉之间的关系。方法:本随机对照,单盲试验包括88名男女职前教师,年龄22.8±1.2岁。学习风格问卷,标尺跌落试验,对参与者进行了六字母消除测试,并随机分为两组。实验组(由ChoaKokSui大师介绍的彼此面对的手)和假(面对相反的手)练习手敏化。提供了半结构化问卷,以收集有关生物场感觉的信息以及双手之间体验这些感觉所需的时间。结果:实验组(N=44)中的所有(100%)参与者和假手术组(N=13)中的29.55%参与者报告经历了生物场感觉。发现了显著的差异,磁性,温度变化,实验组和假手术组之间的疼痛感觉(X2=59.20,p<.001)。在实验组中,第一次体验磁性感觉所需的平均时间,其他生物场感觉和温度变化分别为34.84±12.97、40.28±20.96和42.50±19.79。首次体验生物场感觉所需的最短时间为5秒,并持续到120秒的研究持续时间。在我们的观察中,我们发现体验的总体持续时间和第一次体验所花费的时间之间存在显著的负相关,虽然反应时间之间没有发现相关性,注意,以及体验生物场感觉所需的时间。结论:本研究描述了体验新颖生物场感觉的持续时间。
    Aims: There is minimal research on the duration of biofield experiences. This preliminary study used the experiential learning practice of Master Choa Kok Sui\'s hands sensitisation to determine the duration to experience biofield sensations in between hands and to find the relationship between learning style preferences and biofield sensations. Methods: This randomised controlled, single blinded trial included 88 male and female pre-service teachers, aged 22.8 ±1.2 years. Learning Style questionnaire, Ruler drop test, and Six Letter Cancellation tests were administered to participants and randomised into two groups. The experimental (hands facing each other as introduced by Master Choa Kok Sui) and sham (hands facing opposite) groups practiced hands sensitisation. A semi-structured questionnaire was provided to gather information about biofield sensations and the time it took to experience these sensations between the hands. Results: All (100%) of the participants in the experimental group (N=44) and 29.55% in the sham group (N=13) reported experiencing biofield sensations. A significant difference was found in, magnetic, temperature variation, and pain sensations between experimental and sham groups (X 2= 59.20, p<.001). In the experimental group, the average time taken to first experience magnetic sensation, other biofield sensations and temperature variation was 34.84±12.97, 40.28± 20.96 and 42.50±19.79, respectively. Minimum time taken to first experience biofield sensation was 5 seconds and lasted up to study duration of 120 seconds. In our observations, we found a significant negative correlation between the overall duration of experiences and the time it took for the first experience, while there was no correlation found between reaction time, attention, and the time needed to experience biofield sensations. Conclusions: The duration to experience the novel biofield sensation was described in this study.

    背景:可卡因渴求是可卡因使用障碍(CUD)的主要症状。虚拟现实提示暴露疗法的渴望(VRCET)允许更身临其境,现实的,与传统的非VR提示暴露疗法(CET)相比,可控暴露,其在治疗物质使用障碍方面的功效有限。这项研究的目的是评估VRCET的疗效和可接受性,作为独立和附加干预(即,结合认知疗法),与基于图片的CET(PCET)相比,减少因CUD住院的住院患者自我报告的可卡因渴望。
    方法:54名因CUD住院的患者将被随机分为两个为期3周的强化治疗组之一:10次会议/2周治疗VRCET加5次会议/1周治疗以记忆为中心的认知疗法(MFCT;实验臂),或15次会议/3周治疗PCET(主动控制臂)。渴望体验问卷(CEQ-F&S)将用于评估主要结果,即,治疗后自我报告的可卡因渴求频率(过去2周内)和强度评分(在VR暴露于可卡因提示下)降低.次要终点包括尿,生理,和自我报告的可卡因使用相关措施。评估计划在预处理时进行,治疗2周后(即VRCETvs.PCET),治疗后(3周,即,VRCET+MFCTvs.PCET),在1个月的随访中。可接受性将通过(i)沉浸式环境的空间存在-沿VRCET的网络疾病和(ii)治疗2周后和治疗后的客户满意度问卷进行评估。
    结论:这项研究将首次评估VRCET对CUD的可接受性和有效性,作为心理治疗的附加组件,减少可卡因的渴望频率和强度。此外,这项研究将提供有关VRCET特定兴趣的证据,与非基于VR的CET相比,作为治疗物质使用障碍的线索反应性和暴露范例。
    背景:NCT05833529[clinicaltrials.gov]。预计于2023年4月17日注册。
    BACKGROUND: Cocaine craving is a central symptom of cocaine use disorders (CUD). Virtual reality cue-exposure therapy for craving (VRCET) allows more immersive, realistic, and controllable exposure than traditional non-VR cue-exposure therapy (CET), whose efficacy is limited in treating substance use disorders. The purpose of this study is to evaluate the efficacy and acceptability of VRCET, as a stand-alone and add-on intervention (i.e., combined with cognitive therapy), compared to a picture-based CET (PCET), in reducing self-reported cocaine craving in inpatients hospitalized for CUD.
    METHODS: Fifty-four inpatients hospitalized for CUD will be randomized in one of two intensive 3-week treatment arms: 10 meetings/2-week treatment of VRCET plus 5 meetings/1-week treatment of memory-focused cognitive therapy (MFCT; experimental arm), or 15 meetings/3-week treatment of PCET (active control arm). The Craving Experience Questionnaire (CEQ - F & S) will be used to assess the primary outcome, i.e., the post-treatment decrease of self-reported cocaine craving frequency (within the past 2 weeks) and intensity scores (in VR exposure to cocaine cues). Secondary endpoints include urinary, physiological, and self-reported cocaine use-related measures. Assessments are scheduled at pretreatment, after 2 weeks of treatment (i.e., VRCET vs. PCET), post-treatment (3 weeks, i.e., VRCET + MFCT vs. PCET), and at 1-month follow-up. Acceptability will be evaluated via (i) the Spatial Presence for Immersive Environments - Cybersickness along VRCET and (ii) the Client Satisfaction Questionnaires after 2 weeks of treatment and post-treatment.
    CONCLUSIONS: This study will be the first to evaluate the acceptability and efficacy of VRCET for CUD, as a psychotherapeutic add-on, to reduce both cocaine craving frequency and intensity. Additionally, this study will provide evidence about the specific interest of VRCET, compared to a non-VR-based CET, as a cue reactivity and exposure paradigm for treating substance use disorders.

    背景:偏瘫肩痛(HSP)是中风后常见的并发症。严重影响上肢运动功能的恢复。偏瘫患者早期肩痛主要是由中枢神经损伤或神经可塑性引起的神经性疼痛。在肩关节中常用的皮质类固醇注射可以减轻肩痛;然而,副作用还包括软组织退化或肌腱脆性增加,长期影响仍然存在争议。肉毒杆菌毒素注射相对较新,被认为可以阻断肩关节腔中疼痛受体的传递,并抑制神经致病物质的产生,以减少神经源性炎症。有研究认为,中风后偏瘫的肩痛是由与肩关节疼痛有关的中枢系统改变引起的,持续性疼痛可能导致皮质感觉中枢或运动中枢的重组。然而,目前尚无确凿的证据表明肉毒杆菌毒素对疼痛的改善是否会影响脑功能。在以前的研究中,肉毒杆菌毒素与糖皮质激素(曲安奈德注射液)治疗肩痛,缺乏观察大脑功能变化的差异。由于以前评估疼痛改善的内容主要是主观的,缺乏客观量化的考核指标。功能性近红外成像(fNIRS)可以解决这个问题。
    方法:本研究方案是为双盲,无肱二头肌长腱鞘炎或肩峰滑囊炎的卒中后HSP患者的随机对照临床试验。78名患者将被随机分配到A型肉毒杆菌毒素组或糖皮质激素组。在基线,每组患者将接受肩部腔注射肉毒杆菌毒素或糖皮质激素,随访1周和4周.主要结果是视觉模拟量表(VAS)上的肩痛变化。次要结果是通过fNIRS成像评估相应脑区的氧合血红蛋白水平变化,肩部屈曲,外部旋转运动范围,上肢Fugl-Meyer,并修改了Ashworth分数。
    结论:超声引导下A型肉毒杆菌毒素肩关节腔注射可能为HSP患者疼痛改善提供证据。这项试验的结果也有助于分析肩痛的变化与脑血流动力学和肩关节运动功能变化之间的相关性。

    BACKGROUND: Hemiplegic shoulder pain (HSP) is a common complication after stroke. It severely affects the recovery of upper limb motor function. Early shoulder pain in hemiplegic patients is mainly neuropathic caused by central nerve injury or neuroplasticity. Commonly used corticosteroid injections in the shoulder joint can reduce shoulder pain; however, the side effects also include soft tissue degeneration or increased tendon fragility, and the long-term effects remain controversial. Botulinum toxin injections are relatively new and are thought to block the transmission of pain receptors in the shoulder joint cavity and inhibit the production of neuropathogenic substances to reduce neurogenic inflammation. Some studies suggest that the shoulder pain of hemiplegia after stroke is caused by changes in the central system related to shoulder joint pain, and persistent pain may induce the reorganization of the cortical sensory center or motor center. However, there is no conclusive evidence as to whether or not the amelioration of pain by botulinum toxin affects brain function. In previous studies of botulinum toxin versus glucocorticoids (triamcinolone acetonide injection) in the treatment of shoulder pain, there is a lack of observation of differences in changes in brain function. As the content of previous assessments of pain improvement was predominantly subjective, objective quantitative assessment indicators were lacking. Functional near-infrared imaging (fNIRS) can remedy this problem.
    METHODS: This study protocol is designed for a double-blind, randomized controlled clinical trial of patients with post-stroke HSP without biceps longus tenosynovitis or acromion bursitis. Seventy-eight patients will be randomly assigned to either the botulinum toxin type A or glucocorticoid group. At baseline, patients in each group will receive shoulder cavity injections of either botulinum toxin or glucocorticoids and will be followed for 1 and 4 weeks. The primary outcome is change in shoulder pain on the visual analog scale (VAS). The secondary outcome is the assessment of changes in oxyhemoglobin levels in the corresponding brain regions by fNIRS imaging, shoulder flexion, external rotation range of motion, upper extremity Fugl-Meyer, and modified Ashworth score.
    CONCLUSIONS: Ultrasound-guided botulinum toxin type A shoulder joint cavity injections may provide evidence of pain improvement in patients with HSP. The results of this trial are also help to analyze the correlation between changes in shoulder pain and changes in cerebral hemodynamics and shoulder joint motor function.
