    背景:在过去的7年中,美国与阿片类药物相关的死亡人数增加了两倍多,与COVID-19大流行同时开始急剧增加。迫切需要新的治疗选择,可以帮助减轻难治性阿片类药物使用障碍(OUD)的个人和社会影响。深部脑刺激(DBS)一种干预措施,包括在大脑中植入电极以传递电脉冲,是一种潜在的治疗方法。目前在许多精神疾病的临床试验中,包括OUD,DBS用于精神病适应症并非没有争议。一些研究已经检查了使用DBS对抗治疗抵抗抑郁症引起的伦理问题,强迫症,和饮食失调。相比之下,关于将DBS用于OUD的文献有限。
    目的:本研究旨在获得对公众对使用DBS进行OUD的看法的经验神经伦理学见解,特别是通过分析基于网络的关于新闻媒体故事的评论话题。
    方法:对2篇《华盛顿邮报》报纸报道进行了定性主题内容分析,这些报道描述了DBS用于治疗OUD的情况。共有292条评论被纳入分析,每个故事的146条评论,确定评论者提出的主要主题。
    结果:两个样本的评论者提出的主要主题包括对治疗结果的希望和期望,成瘾是否是一种精神健康障碍,以及与资源分配有关的问题。将第一份印刷报纸故事与第二份报纸故事进行比较时,关于DBS作为OUD治疗方法的有争议的评论似乎有所减少。相比之下,与治疗需求相关的评论数量随着时间的推移而增加.
    结论:公众对DBS作为OUD治疗方法的观点通过这种定性的主题内容分析阐明了主题,包括总体的社会政治问题,关于技术使用的立场,以及技术和科学问题。更好地了解公众对使用DBS进行OUD的看法,可以帮助解决有关使用DBS进行OUD的错误信息和误解,并确定与其他精神疾病相比,DBS专门用于OUD时在伦理问题上的异同。
    BACKGROUND: The number of opioid-related deaths in the United States has more than tripled over the past 7 years, with a steep increase beginning at the same time as the COVID-19 pandemic. There is an urgent need for novel treatment options that can help alleviate the individual and social effects of refractory opioid use disorder (OUD). Deep brain stimulation (DBS), an intervention that involves implanting electrodes in the brain to deliver electrical impulses, is one potential treatment. Currently in clinical trials for many psychiatric conditions, including OUD, DBS\'s use for psychiatric indications is not without controversy. Several studies have examined ethical issues raised by using DBS to counter treatment-resistant depression, obsessive-compulsive disorder, and eating disorders. In contrast, there has been limited literature regarding the use of DBS for OUD.
    OBJECTIVE: This study aims to gain empirical neuroethical insights into public perceptions regarding the use of DBS for OUD, specifically via the analysis of web-based comments on news media stories about the topic.
    METHODS: Qualitative thematic content analysis was performed on 2 Washington Post newspaper stories that described a case of DBS being used to treat OUD. A total of 292 comments were included in the analysis, 146 comments from each story, to identify predominant themes raised by commenters.
    RESULTS: Predominant themes raised by commenters across the 2 samples included the hopes and expectations with treatment outcomes, whether addiction is a mental health disorder, and issues related to resource allocation. Controversial comments regarding DBS as a treatment method for OUD seemingly decreased when comparing the first printed newspaper story to the second. In comparison, the number of comments relating to therapeutic need increased over time.
    CONCLUSIONS: The general public\'s perspectives on DBS as a treatment method for OUD elucidated themes via this qualitative thematic content analysis that include overarching sociopolitical issues, positions on the use of technology, and technological and scientific issues. A better understanding of the public perceptions around the use of DBS for OUD can help address misinformation and misperceptions about the use of DBS for OUD, and identify similarities and differences regarding ethical concerns when DBS is used specifically for OUD compared to other psychiatric disorders.

    经常提到数字讲故事的变革性和治疗性好处,然而这仍然是一个探索不足的领域,我们在这项研究中展望了这一点。
    采用了现象学研究设计,通过访谈来探索患者声音故事讲述者的目的样本是如何参与多个数字故事讲述者的。分析是通过主题编码,范曼宁生活世界存在性框架的语言分析和使用。
    我们发现,对于这个特定的群体,重新集中和重新构建个人意义的治疗性和变革性经验是通过人际关系来实现的,可以理解为社会学习的过程。生活世界的存在性分析表明,幸福的多元化和关系概念成立,这与Yalom的11种治疗因素之间存在着密切的关系。
    借鉴群体分析文献,我们建议社会学习方法的概念有助于进一步研究,旨在了解数字讲故事方法在医疗保健中的有益影响,并在该领域提供证据,以忠实于生活经验为中心。
    UNASSIGNED: References to transformative and therapeutic benefits of digital storytelling are often made, yet this remains an under-explored area, which we foreground in this study.
    UNASSIGNED: A phenomenological research design was adopted to explore through interview how a purposive sample of Patient Voices storytellers experienced participation in more than one digital storytelling workshop. Analysis was through thematic coding, linguistic analysis and use of van Manen\'s lifeworld existentials framework.
    UNASSIGNED: We find that for this particular group, the therapeutic and transformative experiences that re-centre and re-frame personal meaning do so through inter-personal connections and can be understood as a process of social learning. The lifeworld existentials analysis demonstrates that a pluralist and relational conception of wellbeing holds and there is a close relationship between this and Yalom\'s 11 therapeutic factors.
    UNASSIGNED: Drawing on group analytic literature, we suggest the concept of a social learning methodology as useful in grounding further research that seeks to understand the beneficial impacts of digital storytelling methodologies in healthcare and in contributing evidence in this field with fidelity to the lived experience as central.

    CT1812是一部小说,sigma-2受体(S2R)的脑渗透小分子调节剂,目前正在临床开发用于治疗阿尔茨海默病(AD)。临床前和早期临床数据表明,通过S2R,CT1812选择性地防止和取代淀粉样蛋白β(Aβ)寡聚体与神经元突触的结合,并改善AD动物模型中的认知功能。SHINE是一个正在进行的第二阶段随机,双盲,安慰剂对照临床试验(COG0201)在轻度至中度AD参与者中,旨在评估CT1812治疗6个月的安全性和有效性。为了阐明AD患者的作用机制和CT1812的药效学生物标志物,本研究报告了对SHINE第一组患者进行中期分析的18名参与者的探索性脑脊液(CSF)生物标志物数据(A部分)。基于非靶向质谱的发现蛋白质组学在患者CSF中检测到>2000种蛋白质,并且在加速鉴定反映淀粉样蛋白和tau蛋白以外的多种病理生理学的新型AD生物标志物方面具有文献记载的实用性。并能够在纵向介入试验中鉴定药效学生物标志物。我们利用这种技术来分析在基线和CT1812治疗6个月后采集的CSF样品。使用串联质谱(TMT-MS)检测全蛋白质组的蛋白质水平,计算每个参与者的基线变化,并按治疗组进行差异丰度分析。该分析揭示了一组受CT1812显着影响的蛋白质,包括通路参与生物标志物(即,与S2R生物学相关的生物标志物)和疾病修饰生物标志物(即,AD中水平改变的生物标志物与健康对照CSF,但通过CT1812恢复正常,生物标志物与ADAS-Cog11评分的有利趋势相关)。大脑网络映射,基因本体论,通路分析揭示了CT1812对突触的影响,脂蛋白和淀粉样蛋白β生物学,和神经炎症。总的来说,这些研究结果突出了该方法在药效学生物标志物鉴定中的实用性,并为CT1812提供了机制见解,这可能有助于CT1812的临床开发,并能够在即将进行的CT1812临床试验中对生物标志物进行适当的预规范.
    CT1812 is a novel, brain penetrant small molecule modulator of the sigma-2 receptor (S2R) that is currently in clinical development for the treatment of Alzheimer\'s disease (AD). Preclinical and early clinical data show that, through S2R, CT1812 selectively prevents and displaces binding of amyloid beta (Aβ) oligomers from neuronal synapses and improves cognitive function in animal models of AD. SHINE is an ongoing phase 2 randomized, double-blind, placebo-controlled clinical trial (COG0201) in participants with mild to moderate AD, designed to assess the safety and efficacy of 6 months of CT1812 treatment. To elucidate the mechanism of action in AD patients and pharmacodynamic biomarkers of CT1812, the present study reports exploratory cerebrospinal fluid (CSF) biomarker data from 18 participants in an interim analysis of the first set of patients in SHINE (part A). Untargeted mass spectrometry-based discovery proteomics detects >2000 proteins in patient CSF and has documented utility in accelerating the identification of novel AD biomarkers reflective of diverse pathophysiologies beyond amyloid and tau, and enabling identification of pharmacodynamic biomarkers in longitudinal interventional trials. We leveraged this technique to analyze CSF samples taken at baseline and after 6 months of CT1812 treatment. Proteome-wide protein levels were detected using tandem mass tag-mass spectrometry (TMT-MS), change from baseline was calculated for each participant, and differential abundance analysis by treatment group was performed. This analysis revealed a set of proteins significantly impacted by CT1812, including pathway engagement biomarkers (i.e., biomarkers tied to S2R biology) and disease modification biomarkers (i.e., biomarkers with altered levels in AD vs. healthy control CSF but normalized by CT1812, and biomarkers correlated with favorable trends in ADAS-Cog11 scores). Brain network mapping, Gene Ontology, and pathway analyses revealed an impact of CT1812 on synapses, lipoprotein and amyloid beta biology, and neuroinflammation. Collectively, the findings highlight the utility of this method in pharmacodynamic biomarker identification and providing mechanistic insights for CT1812, which may facilitate the clinical development of CT1812 and enable appropriate pre-specification of biomarkers in upcoming clinical trials of CT1812.

    感觉性周围神经病变是糖尿病的常见并发症,也是糖尿病足溃疡的最大危险因素。目前没有可用的治疗方法可以逆转糖尿病人群的感觉丧失。机械噪声的应用已被证明可以在短期内提高振动感知阈值或足底感觉(通过随机共振),但是治疗用途,和长期影响还没有被探索。在这项研究中,22名参与者在治疗上使用了振动鞋垫,每天30分钟,每天,一个月的糖尿病患者感觉性周围神经病变。在该队列中,振动鞋垫的治疗应用显着改善了VPT,平均干预后为8.5V(p=0.001),冲洗后为8.2V(p<0.001)。这种统计学和临床相关的改善可以在预防糖尿病足溃疡和延迟随后的下肢截肢中起作用。
    Sensory peripheral neuropathy is a common complication of diabetes mellitus and the biggest risk factor for diabetic foot ulcers. There is currently no available treatment that can reverse sensory loss in the diabetic population. The application of mechanical noise has been shown to improve vibration perception threshold or plantar sensation (through stochastic resonance) in the short term, but the therapeutic use, and longer-term effects have not been explored. In this study, vibrating insoles were therapeutically used by 22 participants, for 30 min per day, on a daily basis, for a month by persons with diabetic sensory peripheral neuropathy. The therapeutic application of vibrating insoles in this cohort significantly improved VPT by an average of 8.5 V (p = 0.001) post-intervention and 8.2 V (p < 0.001) post-washout. This statistically and clinically relevant improvement can play a role in protection against diabetic foot ulcers and the delay of subsequent lower-extremity amputation.

    背景与目的腕管松解术(CTR)的手术技术已逐渐变得侵入性较小。没有大量证据支持用新型微创方法代替开放式腕管松解术(OCTR)。螺纹腕管松解术(TCTR)是一种新的微创CTR方法,具有良好的效果。本研究旨在比较OCTR和TCTR的美学和功能结果。材料与方法本研究是在德黑兰的一家医院进行的一项随机临床试验,伊朗,2022年。通过简单的随机化将患者随机分为OCTR和TCTR组。人口统计等数据,神经传导研究,肌电图,疼痛,在基线和3个月后记录患者的单丝测试和感官评估。通过评估手术后3个月的瘢痕长度和患者满意度进行美学评估。结果20例(每组10例)进入最终分析。神经传导研究,肌电图,术后3个月,两组感觉评价相似。与OCTR组相比,TCTR组具有较低的术后疼痛(p<0.001)和较低的瘢痕长度(p<0.001)。TCTR和OCTR之间的总体满意度没有统计学差异。结论TCTR法治疗CTS是安全的,其疗效与OCTR相似。它可能是OCTR的一个很好的选择,具有更好的美学效果。
    Background and Objectives  Surgical techniques for carpal tunnel release (CTR) have gradually become less invasive. No substantial evidence supports replacing the open carpal tunnel release (OCTR) with novel minimally invasive approaches. Thread carpal tunnel release (TCTR) is a new minimally invasive CTR method associated with promising results. This study aimed to compare the aesthetic and functional outcomes of OCTR with TCTR. Materials and Methods  This study was a randomized clinical trial conducted in a hospital in Tehran, Iran, in 2022. Patients were randomized to OCTR and TCTR groups through simple randomization. Data such as demographics, nerve conduction study, electromyography, pain, and sensory evaluation by monofilament test were recorded in patients at baseline and after 3 months. Aesthetic evaluation was conducted by assessing the scar length and patients\' satisfaction 3 months after the surgery. Results  Twenty patients (10 in each group) entered the final analysis. Nerve conduction study, electromyography, and sensory evaluation were similar between groups 3 months after the operation. The TCTR group had lower postsurgical pain ( p  < 0.001) and lower scar length ( p  < 0.001) compared to the OCTR group. Overall satisfaction was not statistically different between TCTR and OCTR. Conclusion  The TCTR method is safe in patients with CTS, and its efficacy is similar to OCTR. It can be a good alternative for OCTR, with a better aesthetic outcome.

    治疗依从性(TC)是指患者对医生的处方和建议的依从性。癌症患者通常表现出不令人满意的TC。我们研究的目的是评估癌症患者的TC水平,并确定依从性差的预测因素。作者于2023年3月在肿瘤学中心进行了一项横断面研究,绝大多数医疗活动都是在日间医院进行的。使用问卷或调查测量TC。分析各种参数以确定不良治疗依从性的预测因素。作者的研究包括175名癌症患者,平均年龄为55岁。研究表明,85%的患者表现出良好的依从性(GC),如CI[8.500±0.075]所示,表示患者坚持他们的用药时间表。相反,15%的人表现出较差的合规性(PC),如置信区间[0.825±0.750]所示。通过将遵守规定的用药时机的患者视为良好依从性(GC),而未遵守的患者视为不良依从性(PC)来评估依从性状态。对我们研究结果的分析表明,不良的治疗依从性与较低的社会经济和教育水平有关。因此,重要的是利用所有可用资源来提高治疗依从性。导致依从性差的大多数因素可以通过患者与其支持网络之间的有效协调来缓解。
    Therapeutic compliance (TC) refers to the patient\'s compliance with the prescriptions and recommendations of a doctor. Patients with cancer often exhibit unsatisfactory TC. The objective of our study was to assess TC levels in cancer patients and identify predictors of poor compliance. The authors conducted a cross-sectional study in March 2023 at the oncology centre, where the vast majority of medical activity is performed in the day hospital. TC was measured using a questionnaire or survey. Various parameters were analyzed to identify predictive factors of poor therapeutic compliance. The authors\' study included 175 cancer patients with a mean age of 55 years. The study revealed that 85% exhibited good compliance (GC) as indicated by the CI [8.500 ± 0.075], signifying patients who consistently adhered to their medication schedule. Conversely, 15% demonstrated poor compliance (PC), as indicated by the confidence interval [0.825 ± 0.750]. Compliance status was assessed by considering patients who adhered to the prescribed medication timing as good compliance (GC) and those who did not adhere as poor compliance (PC). The analysis of our study results indicated that poor therapeutic compliance was associated with low socio-economic and educational levels. Therefore, it is important to utilize all available resources to improve therapeutic compliance. The majority of factors contributing to poor compliance can be mitigated through effective coordination between the patient and their support network.

    BACKGROUND: Functional impairment is one of the most decisive prognostic factors in patients with complex chronic diseases. A more significant functional impairment indicates that the disease is progressing, which requires implementing diagnostic and therapeutic actions that stop the exacerbation of the disease.
    OBJECTIVE: This study aimed to predict alterations in the clinical condition of patients with complex chronic diseases by predicting the Barthel Index (BI), to assess their clinical and functional status using an artificial intelligence model and data collected through an internet of things mobility device.
    METHODS: A 2-phase pilot prospective single-center observational study was designed. During both phases, patients were recruited, and a wearable activity tracker was allocated to gather physical activity data. Patients were categorized into class A (BI≤20; total dependence), class B (2060; moderate or mild dependence, or independent). Data preprocessing and machine learning techniques were used to analyze mobility data. A decision tree was used to achieve a robust and interpretable model. To assess the quality of the predictions, several metrics including the mean absolute error, median absolute error, and root mean squared error were considered. Statistical analysis was performed using SPSS and Python for the machine learning modeling.
    RESULTS: Overall, 90 patients with complex chronic diseases were included: 50 during phase 1 (class A: n=10; class B: n=20; and class C: n=20) and 40 during phase 2 (class B: n=20 and class C: n=20). Most patients (n=85, 94%) had a caregiver. The mean value of the BI was 58.31 (SD 24.5). Concerning mobility aids, 60% (n=52) of patients required no aids, whereas the others required walkers (n=18, 20%), wheelchairs (n=15, 17%), canes (n=4, 7%), and crutches (n=1, 1%). Regarding clinical complexity, 85% (n=76) met patient with polypathology criteria with a mean of 2.7 (SD 1.25) categories, 69% (n=61) met the frailty criteria, and 21% (n=19) met the patients with complex chronic diseases criteria. The most characteristic symptoms were dyspnea (n=73, 82%), chronic pain (n=63, 70%), asthenia (n=62, 68%), and anxiety (n=41, 46%). Polypharmacy was presented in 87% (n=78) of patients. The most important variables for predicting the BI were identified as the maximum step count during evening and morning periods and the absence of a mobility device. The model exhibited consistency in the median prediction error with a median absolute error close to 5 in the training, validation, and production-like test sets. The model accuracy for identifying the BI class was 91%, 88%, and 90% in the training, validation, and test sets, respectively.
    CONCLUSIONS: Using commercially available mobility recording devices makes it possible to identify different mobility patterns and relate them to functional capacity in patients with polypathology according to the BI without using clinical parameters.

    近年来,人们对天然化合物的治疗潜力越来越感兴趣,特别是植物来源,由于它们的抗炎特性。其中,西药房室,通常被称为腰果,由于其公认的健康益处,已经引起了极大的关注。本研究旨在建立西麻提取物中所含的生物活性化合物与其抗炎活性之间的相关性。以干燥的西洋无心叶粉为提取基质。提取技术是浸渍,加压流体抽取(PFE),和超临界流体萃取(SFE)。通过LC-MS/MS进行提取物的初步分析。响应面法(RSM),主成分分析(PCA),和热图用于模拟实验条件对植物中特定化合物的提取率和峰面积的影响。为了评估抗炎活性,培养RAW264.7细胞,用LPS激活,并用不同浓度的植物提取物处理。使用XTT测定评估细胞增殖。的确,西西无心提取物含有无心酸,卡卡诺尔斯,还有Cardol,通过SFE和基于乙醇的方法产生不同的概况。RSM显示温度和乙醇,作为CO2的添加剂,显著影响PFE和SFE的提取效率。此外,这种具有SFE的组合物对特定组的化合物表现出更高的选择性。提取物在巨噬细胞中表现出抗炎特性而没有细胞毒性,降低活化细胞中促炎蛋白COX-2、COX-1和TLR4的水平。这表明它们作为抗炎剂的潜力,对未活化细胞中的细胞活力或促炎蛋白水平没有不利影响。总的来说,这些发现强调了西药无心提取物在减轻炎症方面的有希望的治疗潜力,同时也为优化目标化合物分离的提取过程提供了重要的见解。因此,这为该植物开发消炎药提供了良好的前景。
    In recent years, there has been a growing interest in the therapeutic potential of natural compounds, particularly of plant origin, owing to their demonstrated anti-inflammatory properties. Among these, Anacardium occidentale, commonly known as cashew, has garnered significant attention due to its reputed health benefits. This study aim to establish a correlation between the bioactive compounds contained in the extracts of Anacardium occidentale and its anti-inflammatory activity. Dried Anacardium occidentale leaves powder was used as the extraction matrix. Extraction techniques are maceration, pressurized fluid extraction (PFE), and supercritical fluid extraction (SFE). The preliminary analysis of extracts was made by LC-MS/MS. The Response Surface Methodology (RSM), Principal Component Analysis (PCA), and heat maps were employed to model the influence of experimental conditions on extraction yield and peak area of specific compounds from the plant. To evaluate anti-inflammatory activity, RAW 264.7 cells were cultured, activated with LPS, and treated with varying concentrations of the plant extracts. Cell proliferation was assessed using the XTT assay. Indeed, Anacardium occidentale extracts contain anacardic acids, cardanols, and cardol, with distinct profiles yielded by SFE and ethanol-based methods. RSM shows that temperature and ethanol, as additives to CO2, significantly affect extraction efficiency in both PFE and SFE. Moreover, this composition with SFE demonstrate higher selectivity for specific group of compounds. The extracts exhibit anti-inflammatory properties without cytotoxicity in macrophages, reducing levels of pro-inflammatory proteins COX-2, COX-1, and TLR4 in activated cells. This suggests their potential as anti-inflammatory agents without adverse effects on cell viability or pro-inflammatory protein levels in non-activated cells. Overall, these findings underscore the promising therapeutic potential of Anacardium occidentale extracts in mitigating inflammation, while also providing crucial insights into optimizing the extraction process for targeted compound isolation. Thus, this makes a good prospect for the development of anti-inflammatory drugs from this plant.

    It has been documented that patients with mental or physical disabilities can benefit from being placed within the setting of a natural environment. Consequently, the concept of creating spaces that can enhance health preservation or patient recovery, while also augmenting environmental and aesthetic value, has merged as a contemporary discourse. Green areas around hospitals can offer a great opportunity to incorporate healing gardens to benefit their patients and not only. The aim of this paper is to propose a design for a sensory-therapeutic garden based on key principles derived from selected academic literature, focusing on the application of these principles in a healthcare setting in Cluj-Napoca, Romania. The design was informed also by onsite data collection and analysis, and it aims to create a healing landscape that addresses the needs of patients, healthcare providers, and visitors. This study seeks to augment the discourse in the field by demonstrating the practical application of key therapeutic garden design principles in a specific context and how these principles impacted the design process.
