    最近,植物原料作为生物活性物质的来源受到了越来越多的关注。黑玫瑰果(RosapimpinellifoliaL.)水果可能是食品中潜在功能成分的良好资源,化妆品和制药行业。此外,干燥会影响热敏植物化学物质的组成。然而,较少关注比较黑玫瑰果生物活性化合物,特别是脂肪酸的组成,氨基酸,新鲜和干果中的酚类含量。所以在这项研究中,氨基酸成分(通过氨基酸分析仪),脂肪酸(通过GC-MS),矿物元素(通过原子吸收光谱仪),全面研究了在伊朗自然生长的黑玫瑰果的新鲜和干果中存在的抗氧化剂(通过DPPH)和酚类化合物(通过HPLC)。结果表明,干果水分含量降低了51.55%,和更高水平的总酚类化合物和总糖786.20毫克GAE/100克和15.77克/100克,分别。绿原酸和没食子酸是主要的酚类化合物(109.3mg/g)。同时,亚油酸,油酸,花生酸(85.34%)是最主要的脂肪酸。最主要的氨基酸是谷氨酸,苯丙氨酸,和精氨酸(29.41g/100g)。此外,微量元素Fe和Mn是最主要的元素。总的来说,结果表明,在Arasbaran地区种植的黑玫瑰果果实作为有前途的食物来源资源的潜力和差异,药剂学,化妆品,和育种计划。此外,这些发现证实,黑玫瑰果含有大量的次生代谢产物,可能对人类健康产生积极影响。
    Recently, increased attention has been paid to the raw materials of plants as a source of biologically active substances. Black rosehip (Rosa pimpinellifolia L.) fruits could be a good resource for potential functional components in the food, cosmetic and pharmaceutical industries. Also, drying can influence the composition of heat-sensitive phytochemicals. However, less attention is given to comparing black rosehip bioactive compounds particularly compositions of fatty acid, amino acids, and phenolic content in fresh and dried fruits. So in this study, the amino acid constituents (by amino acid analyzer), fatty acids (by GC-MS), mineral elements (by atomic absorption spectrometer), antioxidant (by DPPH) and phenolic compounds (by HPLC) present in fresh and dried fruits of black rosehip naturally grown in Iran were comprehensively investigated. The results showed that dried fruits had a lower level moisture by 51.55%, and a higher level of total phenolic compounds and total sugar by 786.20 mg GAE/100 g and 15.77 g/100 g, respectively. Chlorogenic acid and gallic acid were the major phenolic compounds (109.3 mg/g). Whilst, linoleic acid, oleic acid, and arachidic acid (85.34%) were the most dominant fatty acids. The most dominant amino acids were glutamic acid, phenylalanine, and arginine (29.41 g/100 g). Also, Fe and Mn as micro-elements were the most dominant elements. In general, the results illustrated the potentials and differences of black rosehip fruits grown in the Arasbaran region as promising resources for food sources, pharmaceutics, cosmetics, and breeding programs. Also, these findings confirm that black rosehip fruits contain significant amounts of secondary metabolites that may positively affect human health.

    急性肾损伤(AKI)是临床恶化和肾毒性的标志。虽然有许多研究提供了早期检测AKI的预测模型,使用基于分布式研究网络(DRN)的时间序列数据预测AKI发生的研究很少见。
    在这项研究中,我们旨在通过将基于可解释长短期记忆(LSTM)的模型应用于使用DRN的肾毒性药物的患者的基于医院电子健康记录(EHR)的时间序列数据来检测AKI的早期发生.
    我们使用DRN对6家医院的数据进行了多机构回顾性队列研究。对于每个机构,使用5种用于AKI的药物构建了基于患者的数据集,并使用可解释的多变量LSTM(IMV-LSTM)模型进行训练。这项研究使用倾向评分匹配来减轻人口统计学和临床特征的差异。此外,证明了每个机构和药物的AKI预测模型贡献变量的时间注意力值,使用单向方差分析确认了病例和对照数据之间非常重要的特征分布差异。
    这项研究分析了8643例和31,012例有和没有AKI的患者,分别,6家医院在分析AKI发作的分布时,万古霉素显示起病较早(中位数12,IQR5-25天),与其他药物相比,阿昔洛韦最慢(中位数23,IQR10-41天)。我们用于AKI预测的时间深度学习模型对大多数药物表现良好。阿昔洛韦在每种药物的受试者工作特征曲线评分下的平均面积最高(0.94),其次是对乙酰氨基酚(0.93),万古霉素(0.92),萘普生(0.90),和塞来昔布(0.89)。根据AKI预测模型中变量的时间注意力值,已证实的淋巴细胞和钙万古霉素的关注度最高,而淋巴细胞,白蛋白,血红蛋白会随着时间的推移而减少,尿液pH值和凝血酶原时间有增加的趋势。
    可以通过基于EHR的DRN应用基于时间序列数据的IMV-LSTM来实现对AKI爆发的早期监测。这种方法可以帮助识别风险因素,并在AKI发生前开出引起肾毒性的药物时,早期发现药物不良反应。
    UNASSIGNED: Acute kidney injury (AKI) is a marker of clinical deterioration and renal toxicity. While there are many studies offering prediction models for the early detection of AKI, those predicting AKI occurrence using distributed research network (DRN)-based time series data are rare.
    UNASSIGNED: In this study, we aimed to detect the early occurrence of AKI by applying an interpretable long short-term memory (LSTM)-based model to hospital electronic health record (EHR)-based time series data in patients who took nephrotoxic drugs using a DRN.
    UNASSIGNED: We conducted a multi-institutional retrospective cohort study of data from 6 hospitals using a DRN. For each institution, a patient-based data set was constructed using 5 drugs for AKI, and an interpretable multivariable LSTM (IMV-LSTM) model was used for training. This study used propensity score matching to mitigate differences in demographics and clinical characteristics. Additionally, the temporal attention values of the AKI prediction model\'s contribution variables were demonstrated for each institution and drug, with differences in highly important feature distributions between the case and control data confirmed using 1-way ANOVA.
    UNASSIGNED: This study analyzed 8643 and 31,012 patients with and without AKI, respectively, across 6 hospitals. When analyzing the distribution of AKI onset, vancomycin showed an earlier onset (median 12, IQR 5-25 days), and acyclovir was the slowest compared to the other drugs (median 23, IQR 10-41 days). Our temporal deep learning model for AKI prediction performed well for most drugs. Acyclovir had the highest average area under the receiver operating characteristic curve score per drug (0.94), followed by acetaminophen (0.93), vancomycin (0.92), naproxen (0.90), and celecoxib (0.89). Based on the temporal attention values of the variables in the AKI prediction model, verified lymphocytes and calcvancomycin ium had the highest attention, whereas lymphocytes, albumin, and hemoglobin tended to decrease over time, and urine pH and prothrombin time tended to increase.
    UNASSIGNED: Early surveillance of AKI outbreaks can be achieved by applying an IMV-LSTM based on time series data through an EHR-based DRN. This approach can help identify risk factors and enable early detection of adverse drug reactions when prescribing drugs that cause renal toxicity before AKI occurs.

    背景:心血管疾病患者不坚持用药会损害预期的治疗结果。eHealth干预措施成为有效解决这一问题的有希望的策略。
    目的:这项研究的目的是进行网络荟萃分析(NMA),以比较和排名各种电子健康干预措施在改善心血管疾病(CVDs)患者服药依从性方面的功效。
    方法:在PubMed中进行了系统的搜索策略,Embase,WebofScience,科克伦,中国国家知识基础设施图书馆(CNKI),中国科技期刊数据库(维普),和万方数据库搜索从2024年1月15日开始发表的随机对照试验(RCT)。我们进行了频繁的NMA来比较各种电子健康干预措施的疗效。使用Cochrane手册(2.0版)中的偏见风险工具评估文献的质量,提取的数据使用Stata16.0(StataCorpLLC)和RevMan5.4软件(CochraneCollaboration)进行分析.使用建议分级评估证据的确定性,评估,发展,和评估(等级)方法。
    结果:共纳入21项RCTs,涉及3904例患者。NMA显示,联合干预(标准化平均差[SMD]0.89,95%CI0.22-1.57),电话支持(SMD0.68,95%CI0.02-1.33),远程监护干预措施(SMD0.70,95%CI0.02-1.39),和手机应用干预(SMD0.65,95%CI0.01-1.30)在统计学上优于常规治疗。然而,SMS与平常照护比拟无统计学差别。值得注意的是,联合干预,累积排名曲线下的曲面为79.3%,似乎是最有效的心血管疾病患者的选择。关于收缩压和舒张压结果,联合干预措施成为最佳干预措施的可能性也最高.
    结论:研究表明,联合干预(SMS短信和电话支持)最有可能成为改善心血管疾病患者服药依从性的最有效的电子健康干预措施。其次是远程监测,电话支持,和应用程序干预。这些网络荟萃分析的结果可以为医疗保健提供者提供关键的循证支持,以提高患者的用药依从性。鉴于电子健康干预措施的设计和实施存在差异,进一步大规模,需要精心设计的多中心试验。

    BACKGROUND: Nonadherence to medication among patients with cardiovascular diseases undermines the desired therapeutic outcomes. eHealth interventions emerge as promising strategies to effectively tackle this issue.
    OBJECTIVE: The aim of this study was to conduct a network meta-analysis (NMA) to compare and rank the efficacy of various eHealth interventions in improving medication adherence among patients with cardiovascular diseases (CVDs).
    METHODS: A systematic search strategy was conducted in PubMed, Embase, Web of Science, Cochrane, China National Knowledge Infrastructure Library (CNKI), China Science and Technology Journal Database (Weipu), and WanFang databases to search for randomized controlled trials (RCTs) published from their inception on January 15, 2024. We carried out a frequentist NMA to compare the efficacy of various eHealth interventions. The quality of the literature was assessed using the risk of bias tool from the Cochrane Handbook (version 2.0), and extracted data were analyzed using Stata16.0 (StataCorp LLC) and RevMan5.4 software (Cochrane Collaboration). The certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach.
    RESULTS: A total of 21 RCTs involving 3904 patients were enrolled. The NMA revealed that combined interventions (standardized mean difference [SMD] 0.89, 95% CI 0.22-1.57), telephone support (SMD 0.68, 95% CI 0.02-1.33), telemonitoring interventions (SMD 0.70, 95% CI 0.02-1.39), and mobile phone app interventions (SMD 0.65, 95% CI 0.01-1.30) were statistically superior to usual care. However, SMS compared to usual care showed no statistical difference. Notably, the combined intervention, with a surface under the cumulative ranking curve of 79.3%, appeared to be the most effective option for patients with CVDs. Regarding systolic blood pressure and diastolic blood pressure outcomes, the combined intervention also had the highest probability of being the best intervention.
    CONCLUSIONS: The research indicates that the combined intervention (SMS text messaging and telephone support) has the greatest likelihood of being the most effective eHealth intervention to improve medication adherence in patients with CVDs, followed by telemonitoring, telephone support, and app interventions. The results of these network meta-analyses can provide crucial evidence-based support for health care providers to enhance patients\' medication adherence. Given the differences in the design and implementation of eHealth interventions, further large-scale, well-designed multicenter trials are needed.

    胰高血糖素样肽-1(GLP-1)受体激动剂(RA)是2型糖尿病最常用的药物之一。临床指南推荐GLP-1RA作为慢性肾脏病患者糖尿病治疗的辅助手段。动脉粥样硬化性心血管疾病的存在或风险,和肥胖。临床试验中观察到的体重减轻已在健康个体中进一步探索,使GLP-1RA成为下一个减肥治疗方案。
    尽管不良事件相对安全,大多数GLP-1RA都带有标签,警告甲状腺癌的风险,基于动物模型和一些人类上市后的案例报告。考虑到这种药物的日益普及及其扩展为新的流行适应症,有必要对最新上市后安全性数据进行进一步审查,以量化甲状腺增生和肿瘤病例.
    来自美国食品和药物管理局(FDA)不良事件报告系统数据库的GLP-1RA患者报告使用报告比值比和95%CI进行分析。
    在这项研究中,我们分析了超过1,800万份来自美国FDA不良事件报告系统的报告,提供的证据表明,与服用钠-葡萄糖协同转运蛋白-2(SGLT-2)抑制剂单药治疗的患者相比,服用GLP-1RA单药治疗的患者发生甲状腺增生和肿瘤的倾向显著增加.
    GLP-1RA,不管指示,与SGLT-2抑制剂相比,甲状腺肿瘤和增生不良事件报告增加了10倍以上。
    UNASSIGNED: Glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) are one of the most commonly used drugs for type 2 diabetes mellitus. Clinical guidelines recommend GLP-1 RAs as an adjunct to diabetes therapy in patients with chronic kidney disease, presence or risk of atherosclerotic cardiovascular disease, and obesity. The weight loss observed in clinical trials has been explored further in healthy individuals, putting GLP-1 RAs on track to be the next weight loss treatment.
    UNASSIGNED: Although the adverse event profile is relatively safe, most GLP-1 RAs come with a labeled boxed warning for the risk of thyroid cancers, based on animal models and some postmarketing case reports in humans. Considering the increasing popularity of this drug class and its expansion into a new popular indication, a further review of the most recent postmarketing safety data was warranted to quantify thyroid hyperplasia and neoplasm instances.
    UNASSIGNED: GLP-1 RA patient reports from the US Food and Drug Administration (FDA) Adverse Event Reporting System database were analyzed using reporting odds ratios and 95% CIs.
    UNASSIGNED: In this study, we analyzed over 18 million reports from the US FDA Adverse Event Reporting System and provided evidence of significantly increased propensity for thyroid hyperplasias and neoplasms in patients taking GLP-1 RA monotherapy when compared to patients taking sodium-glucose cotransporter-2 (SGLT-2) inhibitor monotherapy.
    UNASSIGNED: GLP-1 RAs, regardless of indication, are associated with an over 10-fold increase in thyroid neoplasm and hyperplasia adverse event reporting when compared to SGLT-2 inhibitors.

    数字健康技术的成败取决于用户如何接受它。
    我们对使用食品和药物管理局批准的数字健康反馈系统的人员进行了用户体验(UX)评估,该系统包含可摄取传感器(IS)来捕获药物依从性。在他们规定口服暴露前预防(PrEP)以预防HIV感染后。我们对基线参与者特征进行了关联分析,看看是否出现了与积极或消极的UX相关的“角色”。
    UX数据是在一项针对HIV阴性成年人的前瞻性干预研究退出后收集的,规定的口头PrEP,并使用具有IS功能的富马酸替诺福韦酯加恩曲他滨(IS-Truvada)的数字健康反馈系统。基线人口统计学;尿液毒理学;以及评估睡眠的自我报告问卷(匹兹堡睡眠质量指数),自我效能感,习惯性的自我控制,艾滋病毒风险感知(艾滋病毒感知风险量表8项),收集抑郁症状(患者健康问卷-8)。研究中≥28天的参与者完成了Likert量表UX问卷,其中包含27个问题,分为4个领域类别:总体经验,易用性,未来使用的意图,和感知的效用。计算参与者总分数和领域子分数的均值和IQR,线性回归对与用户体验反应相关的基线参与者特征进行建模。使用Fisher精确和Wilcoxon秩和检验比较了响应者与非响应者的人口统计学特征。
    总的来说,71名参与者参加(年龄:平均37.6,范围18-69岁;n=64,90%男性;n=55,77%白人;n=24,34%西班牙裔;n=68,96%居住;n=53,75%就业)。63名使用干预措施≥28天的参与者没有观察到人口统计学差异。完成问卷的参与者更有可能被安置(52/53,98%vs8/10,80%;P=.06),尿液毒理学阳性的可能性较小(18/51,35%vs7/10,70%;P=.08)。特别是甲基苯丙胺(4/51,8%vs4/10,40%;P=0.02),而不是完成者。基于IQR值,根据总分,≥75%的参与者具有良好的UX(中位数3.78,IQR3.17-4.20),总体经验(中位数4.00,IQR3.50-4.50),易用性(中位数3.72,IQR3.33-4.22),和感知效用(中位数3.72,IQR3.22-4.25),≥50%的患者有良好的未来使用意向(中位数3.80,IQR2.80-4.40)。在多预测器建模之后,自我效能感与总分(0.822,95%CI0.405-1.240;P<.001)和所有分得分(均P<.05)显著相关。抑郁症状更多的人报告了更好的感知效用(P=0.01)。睡眠不佳与总体体验较差相关(-0.07,95%CI-0.133至-0.006;P=0.03)。
    使用启用IS的PrEP(IS-Truvada)预防HIV感染的人的UX为阳性。基线参与者特征的关联分析将较高的自我效能感与积极的UX联系起来,抑郁症状更多,感知效用更高,睡眠不足,UX为阴性。
    UNASSIGNED: A digital health technology\'s success or failure depends on how it is received by users.
    UNASSIGNED: We conducted a user experience (UX) evaluation among persons who used the Food and Drug Administration-approved Digital Health Feedback System incorporating ingestible sensors (ISs) to capture medication adherence, after they were prescribed oral pre-exposure prophylaxis (PrEP) to prevent HIV infection. We performed an association analysis with baseline participant characteristics, to see if \"personas\" associated with positive or negative UX emerged.
    UNASSIGNED: UX data were collected upon exit from a prospective intervention study of adults who were HIV negative, prescribed oral PrEP, and used the Digital Health Feedback System with IS-enabled tenofovir disoproxil fumarate plus emtricitabine (IS-Truvada). Baseline demographics; urine toxicology; and self-report questionnaires evaluating sleep (Pittsburgh Sleep Quality Index), self-efficacy, habitual self-control, HIV risk perception (Perceived Risk of HIV Scale 8-item), and depressive symptoms (Patient Health Questionnaire-8) were collected. Participants with ≥28 days in the study completed a Likert-scale UX questionnaire of 27 questions grouped into 4 domain categories: overall experience, ease of use, intention of future use, and perceived utility. Means and IQRs were computed for participant total and domain subscores, and linear regressions modeled baseline participant characteristics associated with UX responses. Demographic characteristics of responders versus nonresponders were compared using the Fisher exact and Wilcoxon rank-sum tests.
    UNASSIGNED: Overall, 71 participants were enrolled (age: mean 37.6, range 18-69 years; n=64, 90% male; n=55, 77% White; n=24, 34% Hispanic; n=68, 96% housed; and n=53, 75% employed). No demographic differences were observed in the 63 participants who used the intervention for ≥28 days. Participants who completed the questionnaire were more likely to be housed (52/53, 98% vs 8/10, 80%; P=.06) and less likely to have a positive urine toxicology (18/51, 35% vs 7/10, 70%; P=.08), particularly methamphetamine (4/51, 8% vs 4/10, 40%; P=.02), than noncompleters. Based on IQR values, ≥75% of participants had a favorable UX based on the total score (median 3.78, IQR 3.17-4.20), overall experience (median 4.00, IQR 3.50-4.50), ease of use (median 3.72, IQR 3.33-4.22), and perceived utility (median 3.72, IQR 3.22-4.25), and ≥50% had favorable intention of future use (median 3.80, IQR 2.80-4.40). Following multipredictor modeling, self-efficacy was significantly associated with the total score (0.822, 95% CI 0.405-1.240; P<.001) and all subscores (all P<.05). Persons with more depressive symptoms reported better perceived utility (P=.01). Poor sleep was associated with a worse overall experience (-0.07, 95% CI -0.133 to -0.006; P=.03).
    UNASSIGNED: The UX among persons using IS-enabled PrEP (IS-Truvada) to prevent HIV infection was positive. Association analysis of baseline participant characteristics linked higher self-efficacy with positive UX, more depressive symptoms with higher perceived utility, and poor sleep with negative UX.

    分布式和即时(POC)制造设施可实现敏捷的制药生产范式,可响应本地化需求,提供个性化和精准医疗。这些功能对于狭窄的治疗指数药物和儿科或老年给药至关重要,在其他专业需求中。先进的增材制造,三维(3D)打印,和按需(DoD)分配技术已开始扩展到药品生产。我们采用设计质量(QbD)方法来识别关键质量属性(CQA),关键材料属性(CMA),和POC制药制造范例的关键工艺参数(CPPs)。该理论框架包括在集中设施生产活性药物成分(API)“油墨”,将其分发到POC站点,以将DoD分发到/分发到交付车辆上(例如,口腔分散膜,胶囊,单剂量液体小瓶)。专注于POC分配/计量过程,QbD考虑和因果分析确定了分配的API数量和固态形式(CQAs),以及喷嘴直径,系统压力通道,和分配的液滴数量(CPP)进行详细调查。从甘油/水的说明性左甲状腺素钠单剂量液体小瓶中测量最终测定定量和含量均匀性CQAs,符合标准验收值。每个POC设施不太可能保持完整的质量控制实验室能力,要求开发适当的在线或在线方法以确保质量控制。我们制定了控制策略,包括在分配前对API墨水进行在线紫外可见(UV-vis)验证,分配过程中的内联液滴计数,中间在线分配体积检查,并在生产后通过液相色谱-串联质谱(LC-MS/MS)进行离线批次确认。
    Distributed and point-of-care (POC) manufacturing facilities enable an agile pharmaceutical production paradigm that can respond to localized needs, providing personalized and precision medicine. These capabilities are critical for narrow therapeutic index drugs and pediatric or geriatric dosing, among other specialized needs. Advanced additive manufacturing, three-dimensional (3D) printing, and drop-on-demand (DoD) dispensing technologies have begun to expand into pharmaceutical production. We employed a quality by design (QbD) approach to identify critical quality attributes (CQAs), critical material attributes (CMAs), and critical process parameters (CPPs) of a POC pharmaceutical manufacturing paradigm. This theoretical framework encompasses the production of active pharmaceutical ingredient (API) \"inks\" at a centralized facility, which are distributed to POC sites for DoD dispensing into/onto delivery vehicles (e.g., orodispersible films, capsules, single liquid dose vials). Focusing on the POC dispensing/dosing processes, QbD considerations and cause-and-effect analyses identified the dispensed API quantity and solid-state form (CQAs), as well as the nozzle diameter, system pressure channel, and number of drops dispensed (CPPs) for detailed investigation. Final assay quantification and content uniformity CQAs were measured from demonstrative levothyroxine sodium single-dose liquid vials of glycerin/water, meeting the standard acceptance values. Each POC facility is unlikely to maintain full quality control laboratory capabilities, requiring the development of appropriate atline or inline methods to ensure quality control. We developed control strategies, including atline ultraviolet-visible (UV-vis) verification of the API ink prior to dispensing, inline drop counting during dispensing, intermediate atline-dispensed volume checks, and offline batch confirmation by liquid chromatography-tandem mass spectrometry (LC-MS/MS) following production.
