Purpose: Infertility is associated with different factors, highly intricated but sometimes ill-defined. Despite the significant recent technological and therapeutic advancements, the success rates of assisted reproductive technologies (ART) remain relatively low. In this context several women have recourse to complementary practices (CP), in the hope of improving success rates and lowering the associated strain. These methods, are quite heterogenous, and are yet to be comprehensively analyzed in the literature. The objective of our study was to evaluate, in women consulting at our fertility center, the current interest in these CP and more specifically, the role of Traditional Chinese Medicine (TCM) and associated Mind Body Intervention (MBI). Methods: A prospective monocentric survey study at the fertility center of the Angers University Hospital between January and May 2022. Results: 150 questionnaires were analyzed. Approximately 50% of women have recourse to CP, in the hope of improving the success rates of ART and reducing the associated stress and fatigue. The main CP used were the ones based on body manipulation, TCM and MBI. The lack of use was mainly linked to a lack of knowledge of these methods, and the vast majority of women would like to receive additional information about CP from the physicians at the center. Conclusion: Our study shows a significant interest in CP in reproductive medicine. In view of the benefits of some of these practices, at least on the quality of life of patients, information on their value should be made available to all couples undergoing ART.
目的:不孕不育与不同的因素有关,这些因素错综复杂,但有时并不明确。尽管最近在技术和治疗方面取得了重大进展,但辅助生殖技术(ART)的成功率仍然相对较低。在这种情况下,一些妇女求助于辅助方法(CP),希望提高成功率并减轻相关压力。这些方法种类繁多,尚未在文献中进行全面分析。我们的研究目的是评估在我们不孕不育中心就诊的妇女目前对这些辅助治疗方法的兴趣,更具体地说,是对传统中医(TCM)和相关的身心干预(MBI)的作用的兴趣。研究方法2022年1月至5月期间在昂热大学医院不孕不育中心进行的前瞻性单中心调查研究。结果:分析了150份问卷:对150份问卷进行了分析。约50%的妇女求助于CP,希望提高抗逆转录病毒疗法的成功率,并减轻相关的压力和疲劳。使用的主要 CP 是基于体操、中医和 MBI 的 CP。不使用的主要原因是对这些方法缺乏了解,绝大多数妇女希望从中心的医生那里获得更多有关 CP 的信息。结论我们的研究表明,人们对生殖医学中的 CP 非常感兴趣。鉴于其中一些方法的益处,至少是对患者生活质量的益处,应向所有接受人工生殖技术的夫妇提供有关这些方法价值的信息。

Importance: Adherence to GLP-1 RA is important for efficacy. Discontinuation and reinitiation patterns for patients with and without type 2 diabetes (T2D) are not well-understood. Objective: To describe rates and factors associated with discontinuation and reinitiation of GLP-1 RA, for patients with and without T2D. Design: In this retrospective cohort study, adults with overweight or obesity initiated on GLP-1 RA between January 2018 and December 2023 were identified using electronic health record (EHR) data from a collective of 30 US healthcare systems. Patients were followed for up to 2 years to assess discontinuation and for 2 additional years to assess reinitiation. Setting: Clinical and prescribing data from EHRs linked to dispensing information Participants: Adults newly initiated on GLP-1 RA between 2018 and 2023, with a baseline BMI [≥]27 and an available weight measurement within 60 days before initiation, and regular care in the year before initiation. Exposure/Covariates: Patients were stratified by presence of T2D at baseline. Associations with socio-demographics, health factors, weight changes, and gastrointestinal (GI) adverse events (AE) were modeled. Main Outcomes and Measures: Proportion of patients discontinuing and reinitiating GLP-1 RA were estimated from Kaplan-Meier models. Associations between covariates and discontinuation and reinitiation outcomes were modeled using time-varying Cox proportional hazards models. All analyses were conducted for patients with and without T2D. Results: Among 96,544 adults initiating GLP-1 RA, the mean (SD) age was 55.1 (13.3) years, 65.2% were female, 73.7% were white, and 61.3% had T2D. Individual income exceeded $50,000 for 49.7% of patients with and 57.2% of patients without T2D. One-year discontinuation was significantly higher for patients without T2D (65.1%), compared to those with T2D (45.8%). Higher weight loss, absence of GI AE, and higher income (T2D only) were significantly associated with higher discontinuation. Of 28,142 (49.6%) who discontinued one-year reinitiation was lower for those without T2D (34.7%), compared to those with T2D (51.0%). Weight re-gain was significantly associated with increased reinitiation. Conclusions and Relevance: Most patients with overweight or obesity discontinue GLP-1 RA within 1 year, but those without T2D discontinue at higher rates and reinitiate at lower rates. Inequities in access and adherence to effective treatments have the potential exacerbate disparities in obesity.
重要性:坚持服用 GLP-1 RA 对疗效非常重要。目前还不十分清楚2型糖尿病(T2D)患者和非2型糖尿病(T2D)患者的停药和复药模式。目的描述 2 型糖尿病(T2D)患者和非 2 型糖尿病(T2D)患者停用和重新启用 GLP-1 RA 的比率和相关因素。设计:在这项回顾性队列研究中,利用来自美国 30 个医疗保健系统的电子健康记录 (EHR) 数据,对 2018 年 1 月至 2023 年 12 月期间开始服用 GLP-1 RA 的超重或肥胖成人进行了鉴定。对患者进行长达 2 年的随访,以评估停药情况,并再进行 2 年的随访,以评估复药情况。研究环境:与配药信息相连接的电子病历中的临床和处方数据 参与者:2018年至2023年期间新开始使用GLP-1 RA的成年人,基线BMI[≥]27,在开始使用前60天内测量过体重,并在开始使用前一年接受过常规治疗。暴露/变量:根据基线时是否患有 T2D 对患者进行分层。与社会人口统计学、健康因素、体重变化和胃肠道 (GI) 不良事件 (AE) 的相关性进行建模。主要结果和测量指标:通过 Kaplan-Meier 模型估算停用和重新启用 GLP-1 RA 的患者比例。协变量与停药和复药结果之间的关系采用时变 Cox 比例危险模型进行建模。所有分析均针对患有和未患有 T2D 的患者进行。结果在96,544名开始使用GLP-1 RA的成人中,平均(标清)年龄为55.1 (13.3)岁,65.2%为女性,73.7%为白人,61.3%患有T2D。49.7%的 T2D 患者和 57.2% 的非 T2D 患者的个人收入超过 50,000 美元。与患有 T2D 的患者(45.8%)相比,未患 T2D 的患者(65.1%)一年后停药的比例明显更高。较高的体重减轻率、无消化道 AE 和较高的收入(仅 T2D 患者)与较高的停药率明显相关。在停药一年的 28142 人(49.6%)中,无 T2D 患者(34.7%)的重新开始率低于 T2D 患者(51.0%)。体重重新增加与重新开始治疗的人数增加有很大关系。结论与意义:大多数超重或肥胖患者在 1 年内停用 GLP-1 RA,但无 T2D 的患者停用率较高,而重新启用率较低。在获得和坚持有效治疗方面的不平等有可能加剧肥胖症的不平等。

Highly mutable pathogens generate viral diversity that impacts virulence, transmissibility, treatment, and thwarts acquired immunity. We previously described C19-SPAR-Seq, a high-throughput, next-generation sequencing platform to detect SARS-CoV-2 that we deployed to systematically profile variant dynamics of SARS-CoV-2 for over 3 years in a large, North American urban environment (Toronto, Canada). Sequencing of the ACE2 receptor binding motif and polybasic furin cleavage site of Spike in over 70,000 patients revealed that population sweeps of canonical variants of concern (VOCs) occurred in repeating wavelets. Furthermore, we found that subvariants and putative quasi-species with alterations characteristic of future VOCs and/or predicted to be functionally important arose frequently, but always extinguished. Systematic screening of functionally relevant domains in pathogens could thus provide a powerful tool for monitoring spread and mutational trajectories, particularly those with zoonotic potential.
高度变异的病原体会产生病毒多样性,从而影响病毒的毒性、传播性、治疗和后天免疫。我们曾介绍过 C19-SPAR-Seq,这是一种用于检测 SARS-CoV-2 的高通量新一代测序平台,我们利用该平台在北美大型城市环境(加拿大多伦多)中对 SARS-CoV-2 的变异动态进行了 3 年多的系统分析。对 7 万多名患者中 Spike 的 ACE2 受体结合基序和多碱性呋喃裂解位点进行测序后发现,相关典型变异体 (VOC) 在人群中以重复小波的形式出现。此外,我们还发现,具有未来 VOCs 特征改变和/或预测具有重要功能改变的亚变异体和准变异体经常出现,但总是消失。因此,对病原体中的功能相关域进行系统筛选可为监测传播和变异轨迹,尤其是那些具有人畜共患病潜能的病原体提供有力的工具。

INTRODUCTION: We evaluated the diagnostic performance of two commercial plasma p-tau217 immunoassays compared to CSF testing and neuropathology. METHODS: 170 plasma samples from University of British Columbia Hospital Clinic for Alzheimer's (AD) and Related Disorders were analyzed for p-tau217 using Fujirebio and ALZpath assays. Decision points were determined using CSF testing and autopsy findings as the standard. RESULTS: Fujirebio and ALZpath p-tau217 had similar overall analytical and clinical performance, with distinct decision points for each assay. Based on autopsy finding, both p-tau217 assays identified individuals with AD from other neurodegenerative diseases (ALZpath AUC = 0.94, Fujirebio AUC= 0.90). The ALZpath assay detected AD pathology at milder disease stages compared to the Fujirebio assay. DISCUSSION: Our study reinforces the clinical utility of plasma p-tau217 as an AD biomarker. Differences in test performance and clinical decision points suggest an assay specific diagnostic approach is required for plasma p-tau217 in clinical practice.
简介:我们评估了两种商用血浆p-tau217免疫测定与脑脊液检测和神经病理学相比的诊断性能。方法:使用 Fujirebio 和 ALZpath 检测法对不列颠哥伦比亚大学医院阿尔茨海默氏症(AD)及相关疾病诊所的 170 份血浆样本进行 p-tau217 分析。以脑脊液检测和尸检结果为标准确定决策点。结果:Fujirebio和ALZpath p-tau217的总体分析和临床表现相似,但每种检测方法都有不同的决定点。根据尸检结果,两种p-tau217检测方法都能从其他神经退行性疾病中鉴别出AD患者(ALZpath的AUC=0.94,Fujirebio的AUC=0.90)。与Fujirebio检测法相比,ALZpath检测法能在较轻的疾病阶段检测到AD病理变化。讨论:我们的研究加强了血浆p-tau217作为AD生物标记物的临床实用性。检测性能和临床决策点的差异表明,在临床实践中需要对血浆p-tau217采用特定的检测诊断方法。

Background: This study investigated the presence of the healthy vaccinee bias in two COVID-19 vaccine effectiveness studies, involving primary series and booster vaccinations, as well as its temporal patterns and variability across different subpopulations, by examining the association between COVID-19 vaccination and non-COVID-19 mortality in Qatar. Methods: Two matched, retrospective cohort studies assessed the incidence of non-COVID-19 death in national cohorts of individuals with a primary series vaccination versus no vaccination (two-dose analysis), and individuals with three-dose (booster) vaccination versus primary series vaccination (three-dose analysis), from January 5, 2021, to April 9, 2024. Results: The adjusted hazard ratio (aHR) for non-COVID-19 death was 0.76 (95% CI: 0.64-0.90) in the two-dose analysis and 0.85 (95% CI: 0.67-1.07) in the three-dose analysis. In the first six months of follow-up in the two-dose analysis, the aHR was 0.35 (95% CI: 0.27-0.46); however, the combined analysis of all subsequent periods showed an aHR of 1.52 (95% CI: 1.19-1.94). In the first six months of follow-up in the three-dose analysis, the aHR was 0.31 (95% CI: 0.20-0.50); however, the combined analysis of all subsequent periods showed an aHR of 1.37 (95% CI: 1.02-1.85). The overall effectiveness of the primary series and third-dose vaccinations against severe, critical, or fatal COVID-19 was 95.9% (95% CI: 94.0-97.1) and 34.1% (95% CI: -46.4-76.7), respectively. Subgroup analyses showed that the healthy vaccinee bias is pronounced among those aged 50 years and older and among those more clinically vulnerable to severe COVID-19. Conclusion: A strong healthy vaccinee bias was observed in the first six months following vaccination. This bias may have stemmed from a lower likelihood of vaccination among seriously ill, end-of-life individuals, and less mobile elderly populations. Despite this bias, vaccination provided strong protection against severe COVID-19.
背景:本研究通过考察卡塔尔 COVID-19 疫苗接种与非 COVID-19 死亡率之间的关系,调查了两项 COVID-19 疫苗有效性研究(涉及初免和加强免疫)中是否存在健康接种者偏倚,以及其在不同亚人群中的时间模式和变异性。方法:两项匹配的回顾性队列研究评估了从 2021 年 1 月 5 日到 2024 年 4 月 9 日期间接种一次初级系列疫苗与未接种疫苗(两剂分析)以及接种三剂(加强型)疫苗与接种一次初级系列疫苗(三剂分析)的全国队列中非 COVID-19 死亡的发生率。结果在两剂分析中,非 COVID-19 死亡的调整危险比 (aHR) 为 0.76(95% CI:0.64-0.90),在三剂分析中为 0.85(95% CI:0.67-1.07)。在两剂分析中,随访前六个月的 aHR 为 0.35(95% CI:0.27-0.46);然而,对随后所有时间段的合并分析显示,aHR 为 1.52(95% CI:1.19-1.94)。在三剂分析的前六个月随访中,aHR 为 0.31(95% CI:0.20-0.50);然而,对随后所有时间段的合并分析显示,aHR 为 1.37(95% CI:1.02-1.85)。接种第一针和第三针疫苗对严重、危重或致命COVID-19的总体有效率分别为95.9%(95% CI:94.0-97.1)和34.1%(95% CI:-46.4-76.7)。亚组分析表明,健康疫苗接种者偏差在 50 岁及以上人群和临床上更易感染严重 COVID-19 的人群中非常明显。结论:在接种疫苗后的头六个月中观察到了强烈的健康接种者偏倚。这种偏差可能是由于重病患者、临终者和行动不便的老年人群接种疫苗的可能性较低。尽管存在这种偏差,接种疫苗仍能有效预防严重的 COVID-19。

Methods: Two matched, retrospective cohort studies assessed the incidence of non-COVID-19 death in national cohorts of individuals with a primary series vaccination versus no vaccination (two-dose analysis), and individuals with three-dose (booster) vaccination versus primary series vaccination (three-dose analysis), from January 5, 2021, to April 9, 2024. Results: The adjusted hazard ratio (aHR) for non-COVID-19 death was 0.76 (95% CI: 0.64-0.90) in the two-dose analysis and 0.85 (95% CI: 0.67-1.07) in the three-dose analysis. In the first six months of follow-up in the two-dose analysis, the aHR was 0.35 (95% CI: 0.27-0.46); however, the combined analysis of all subsequent periods showed an aHR of 1.52 (95% CI: 1.19-1.94). In the first six months of follow-up in the three-dose analysis, the aHR was 0.31 (95% CI: 0.20-0.50); however, the combined analysis of all subsequent periods showed an aHR of 1.37 (95% CI: 1.02-1.85). The overall effectiveness of the primary series and third-dose vaccinations against severe, critical, or fatal COVID-19 was 95.9% (95% CI: 94.0-97.1) and 34.1% (95% CI: -46.4-76.7), respectively. Subgroup analyses showed that the healthy vaccinee bias is pronounced among those aged 50 years and older and among those more clinically vulnerable to severe COVID-19. Conclusion: A strong healthy vaccinee bias was observed in the first six months following vaccination. This bias may have stemmed from a lower likelihood of vaccination among seriously ill, end-of-life individuals, and less mobile elderly populations. Despite this bias, vaccination provided strong protection against severe COVID-19.","PeriodicalId":506788,"journal":{"name":"medRxiv","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141796541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Importance: In mental healthcare, the potential of Large Language Models (LLMs) to enhance psychoeducation is a burgeoning field. This study explored the potential of ChatGPT as an individualized psychoeducational support tool specifically for psychosis education. Objective: The study aims to evaluate psychosis-related questions to provide accurate, clear, and clinically relevant individualized information for patients and caregivers. Design: This cross-sectional study uses a qualitative analysis design. The researchers specifically employed a question-answering system (GPT-4 via ChatGPT) to generate responses to common questions about psychosis. Experts in the field then evaluated these responses to assess their quality for use in a clinical setting. Primary Outcome: Researchers presented ChatGPT with 20 common questions frequently asked by patients' caregivers and relatives. Two experts in psychosis then assessed the quality of the responses using six criteria: accuracy (1-3), clarity (1-3), inclusivity (1-3), completeness (0-1), clinical utility (1-5) and an overall score (1-4). Results: The evaluation yielded positive results overall. Responses were rated as accurate (M:SD= 2.89:0.22) and clear (mean score of 2.93:0.18). There was potential for improvement in terms of inclusivity (mean score of 2.30:0.41), suggesting a need to incorporate more diverse perspectives. Completeness received high ratings (mean score of 0.93:0.18), indicating responses addressed all aspects of the questions. Most importantly, the responses were deemed clinically useful (mean score of 4.35:0.52). Conclusions: In summary, this study underscores the significant promise of ChatGPT as a psychoeducational tool for patients with psychosis, their relatives, and their caregivers. The experts' findings affirm that the information delivered by ChatGPT is not only accurate and clinically relevant but also conveyed conversationally, enhancing its accessibility and usability. The initial performance of ChatGPT as a psychoeducational tool in the context of psychosis education is undeniably positive.

Wastewater-based epidemiology, which seeks to assess disease occurrence in communities through measurements of infectious disease biomarkers in wastewater, may represent a valuable tool for understanding occurrence of hepatitis A infections in communities. In this study, we measured concentrations of Hepatovirus A (HAV) RNA, in samples from 191 wastewater treatment plants spanning 40 US states and the District of Columbia from September 2023 to June 2024 and compared the measurements with traditional measures of disease occurrence. Nationally, 13.76% of the 21,602 wastewater samples were positive for HAV RNA, and both concentrations and positivity rates were associated with NNDSS hepatitis A case data nationally (Kendall rank correlation coefficient = 0.20, concentrations; and 0.33, positivity rate; both p<0.05). We further demonstrated that higher rates of wastewater HAV detection were positively associated with socioeconomic indicators of vulnerability including homelessness and drug overdose deaths (both p<0.0001). Areas with above average levels of homelessness were 48% more likely to have HAV wastewater detections, while areas with above average levels of drug overdose deaths were 14% more likely to have HAV wastewater detections. Using more granular case data, we present a case study in the state of Maine that reinforces these results and suggests a potential lead time for wastewater over clinical case detection and exposure events. The ability to detect HAV RNA in wastewater before clinical cases emerge could allow public health officials to implement targeted interventions like vaccination campaigns.
基于废水的流行病学旨在通过测量废水中的传染病生物标志物来评估社区中的疾病发生情况,它可能是了解社区中甲型肝炎感染发生情况的重要工具。在这项研究中,我们测量了 2023 年 9 月至 2024 年 6 月期间来自美国 40 个州和哥伦比亚特区的 191 家污水处理厂样本中的甲型肝炎病毒 (HAV) RNA 浓度,并将测量结果与传统的疾病发生率测量方法进行了比较。从全国范围来看,21602 份废水样本中有 13.76% 呈 HAV RNA 阳性,浓度和阳性率均与全国 NNDSS 甲型肝炎病例数据相关(Kendall 秩相关系数 = 0.20,浓度;0.33,阳性率;均 p<0.05)。我们进一步证明,较高的废水甲型肝炎病毒检测率与无家可归者和吸毒过量死亡等社会经济弱势指标呈正相关(均 p<0.0001)。无家可归人数高于平均水平的地区检测到 HAV 废水的可能性要高出 48%,而吸毒过量死亡人数高于平均水平的地区检测到 HAV 废水的可能性要高出 14%。通过使用更精细的病例数据,我们介绍了缅因州的一个案例研究,该研究证实了这些结果,并表明废水可能比临床病例检测和暴露事件更早出现。如果能在临床病例出现之前检测到废水中的 HAV RNA,公共卫生官员就可以实施有针对性的干预措施,如开展疫苗接种活动。

Understanding the alterations in brain function across different episodes of bipolar disorder (BD), including manic (BipM), depressive (BipD), and remission states (rBD), poses a significant challenge. In our cross-sectional study, we collected resting-state functional magnetic resonance imaging data from 117 BD patients (BipM: 38, BipD: 42, rBD: 37) and 35 healthy controls. Our aim was to delineate functional connections associated with episode dynamics, delineate common and specific patterns, validate them as biomarkers, and elucidate their biological underpinnings. Initially, we identified a common altered pattern within the sub-regions of the ventral-attention network, alongside specific patterns observed in the default mode network for BipM, the prefrontal network for BipD, and the limbic network for rBD. Using large-sample data from the Human Connectome Project, we further identified that these connectivity patterns exhibit relatively high reliability and heritability. Also, these distinct patterns accurately characterized the diverse episodes of BD and effectively predicted the cor responding clinical symptoms linked with each episode type. Importantly, using out of sample data to decode possible neurobiological mechanisms underlying these patterns, we found that regions of particular interest were enriched in multiple receptors, including MOR, NMDA, and H3 for specific alterations, and A4B2, 5HTT, and 5HT1a for common alterations. Moreover, both episode-specific and common patterns demonstrated a high enrichment for cell types such as L5ET, Micro/PVM,oligodendrites and Chandelier. Our study offers novel insights concerning episode dynamics in BD, paving the way for personalized medicine approaches tailored to address the various episodes.
了解双相情感障碍(BD)不同发作期(包括躁狂(BipM)、抑郁(BipD)和缓解状态(rBD))的大脑功能变化是一项重大挑战。在横断面研究中,我们收集了 117 名双相情感障碍患者(BipM:38 人;BipD:42 人;rBD:37 人)和 35 名健康对照者的静息态功能磁共振成像数据。我们的目的是确定与发作动态相关的功能连接,划分常见和特殊模式,将其验证为生物标记物,并阐明其生物学基础。最初,我们在腹侧注意网络的子区域内发现了一种常见的改变模式,同时还在默认模式网络(BipM)、前额叶网络(BipD)和边缘网络(rBD)中观察到了特定模式。利用人类连接组计划(Human Connectome Project)的大样本数据,我们进一步确定了这些连接模式具有相对较高的可靠性和遗传性。此外,这些独特的模式准确地描述了 BD 不同发作的特征,并有效地预测了与每种发作类型相关的临床症状。重要的是,通过使用样本外数据来解码这些模式背后可能的神经生物学机制,我们发现特别感兴趣的区域富含多种受体,包括特定改变的 MOR、NMDA 和 H3,以及常见改变的 A4B2、5HTT 和 5HT1a。此外,发作特异性和共同模式都显示出 L5ET、Micro/PVM、少突胶质细胞和 Chandelier 等细胞类型的高度富集。我们的研究提供了有关 BD 病程动态的新见解,为针对不同病程的个性化医疗方法铺平了道路。

Class 2 and 3 non-V600E BRAF mutations are oncogenic drivers in many cancer types. Currently, there are no established targeted therapies with proven efficacy for cancers with non-V600E BRAF mutations. We developed the investigator-initiated, Phase II BEAVER clinical trial (NCT03839342) to evaluate the efficacy of BRAF and MEK inhibitors in patients with non-V600E BRAF mutations. The best objective response rate was 14% (3/21). By analyzing genomic data from patient tumors, circulating tumor DNA (ctDNA), patient-derived xenograft (PDX) models generated from enrolled patients, and Class 2 & 3 BRAF mutant cell lines, we discovered MAPK-dependent and independent mechanisms of resistance to BRAF/MEK inhibition. These mechanisms included the acquisition of new mutations in NRAS, MAP2K1, RAF1, and RB in ctDNA at the time of disease progression. CDK4/6 and SHP2 were identified as mediators of intrinsic resistance to BRAF/MEK inhibition in Class 2 & 3 BRAF mutant tumors. Therapeutic strategies combining CDK4/6 or SHP2 inhibitors with BRAF/MEK inhibitors were more effective than BRAF/MEK inhibitors alone in these cancers.
2 类和 3 类非 V600E BRAF 突变是许多癌症类型的致癌驱动因素。目前,对于非 V600E BRAF 突变的癌症还没有疗效确切的靶向疗法。我们开发了由研究者发起的 BEAVER II 期临床试验(NCT03839342),以评估 BRAF 和 MEK 抑制剂对非 V600E BRAF 突变患者的疗效。最佳客观反应率为 14%(3/21)。通过分析患者肿瘤的基因组数据、循环肿瘤 DNA (ctDNA)、由入组患者生成的患者衍生异种移植 (PDX) 模型以及 2 类和 3 类 BRAF 突变细胞系,我们发现了 BRAF/MEK 抑制剂耐药的 MAPK 依赖性和独立机制。这些机制包括疾病进展时ctDNA中NRAS、MAP2K1、RAF1和RB的新突变。CDK4/6和SHP2被确定为2类和3类BRAF突变肿瘤对BRAF/MEK抑制产生内在耐药性的介质。在这些癌症中,将 CDK4/6 或 SHP2 抑制剂与 BRAF/MEK 抑制剂相结合的治疗策略比单独使用 BRAF/MEK 抑制剂更有效。

Introduction Hypersensitivity pneumonitis (HP), a common interstitial lung disease (ILD), comprises two distinct but related forms, acute and fibrotic (fHP). HP is classically described as a disease triggered by antigen exposure. However, a wide range of triggers are described and in ~50% of cases no cause is identified, rendering observational studies challenging. The British Pigeon Fanciers Genetics of ILD (BPF-GILD) study aims to address this by studying a population with a clear history of exposure to a common trigger. Methods Participants were recruited from 2019 to 2023 at large UK Pigeon Fancier meetings. Each participant performed spirometry, completed a standardised questionnaire with a doctor, and provided blood samples. We present our baseline data in this manuscript. Results 417 subjects were recruited from four shows. The median age of the cohort was 63 years, 95% were male and 94% self-reported white ethnicity. The median number of pigeons kept was 80 [range 4-800], with fanciers spending 14 hours per week [1-100] in their lofts. 52% of participants had occupational dust exposures. 49% of the cohort reported at least one respiratory symptom related to loft exposure. 14% had a history of ILD and these individuals had more loft-related respiratory symptoms, poorer lung function, and appeared more likely to wear a mask with their pigeons than those without (74% vs 57%). 41% of participants had positive responses to questions employed to detect occult connective tissue disease in ILD clinics. Discussion Our well characterised cohort of pigeon fanciers commonly experience acute HP symptoms and are likely to be at increased risk of fHP. Subsequent work using stored samples will enable us to determine genetic risk factors and pathways relevant to the development of fHP.
导言 超敏性肺炎(HP)是一种常见的间质性肺病(ILD),包括急性和纤维化(fHP)两种不同但相关的形式。过敏性肺炎通常被描述为一种由抗原暴露引发的疾病。然而,诱发因素的范围很广,约有 50% 的病例找不到病因,因此观察研究具有挑战性。英国鸽友ILD遗传学(BPF-GILD)研究旨在通过研究具有明确常见诱发因素接触史的人群来解决这一问题。方法 从 2019 年到 2023 年,在英国大型鸽友会议上招募参与者。每位参与者都进行了肺活量测定,与医生一起填写了一份标准化问卷,并提供了血液样本。我们在本手稿中介绍了我们的基线数据。结果 我们从四个鸽展中招募了 417 名受试者。受试者的年龄中位数为 63 岁,95% 为男性,94% 自称是白人。饲养鸽子数量的中位数为 80 只[范围为 4-800 只],鸽友每周在鸽舍中的时间为 14 小时[1-100 小时]。52%的参与者接触过职业性粉尘。49%的参与者称至少有一种呼吸道症状与鸽舍接触有关。14%的人有ILD病史,这些人与鸽舍相关的呼吸道症状较多、肺功能较差,而且与没有ILD病史的人相比(74%对57%),这些人似乎更有可能在遛鸽时戴上口罩。41%的参与者对ILD门诊中用来检测隐性结缔组织疾病的问题做出了积极的回答。讨论 我们这批特征明显的鸽友通常会出现急性高血压症状,并有可能增加罹患高血压的风险。利用储存的样本开展的后续工作将使我们能够确定遗传风险因素以及与发生 fHP 相关的途径。

HP is classically described as a disease triggered by antigen exposure. However, a wide range of triggers are described and in ~50% of cases no cause is identified, rendering observational studies challenging. The British Pigeon Fanciers Genetics of ILD (BPF-GILD) study aims to address this by studying a population with a clear history of exposure to a common trigger. Methods Participants were recruited from 2019 to 2023 at large UK Pigeon Fancier meetings. Each participant performed spirometry, completed a standardised questionnaire with a doctor, and provided blood samples. We present our baseline data in this manuscript. Results 417 subjects were recruited from four shows. The median age of the cohort was 63 years, 95% were male and 94% self-reported white ethnicity. The median number of pigeons kept was 80 [range 4-800], with fanciers spending 14 hours per week [1-100] in their lofts. 52% of participants had occupational dust exposures. 49% of the cohort reported at least one respiratory symptom related to loft exposure. 14% had a history of ILD and these individuals had more loft-related respiratory symptoms, poorer lung function, and appeared more likely to wear a mask with their pigeons than those without (74% vs 57%). 41% of participants had positive responses to questions employed to detect occult connective tissue disease in ILD clinics.
