    牛皮癣是一种慢性免疫介导的影响皮肤的疾病,指甲,和/或关节。它与全身性炎症有关,也可能与动脉粥样硬化性心血管疾病(ASCVD)的风险增加有关。这项研究的目的是确定银屑病患者ASCVD的总体风险,并根据ASCVD类型和银屑病的严重程度评估风险。这是一项观察性研究的系统评价和荟萃分析,报告了银屑病与一种或多种ASCVD临床类型之间的关联。我们通过PubMed在线搜索医学文献分析和检索系统(MEDLINE),摘录医学数据库(EMBASE),Scopus,比勒费尔德学术搜索引擎(BASE),和谷歌学者从他们的记录开始到2023年7月的英语相关研究。研究选择和数据提取由四名独立评审员进行。总共21项观察性研究(三项横断面研究,一个病例控制,和17个队列)被包括在这篇综述中,代表总共778,049名牛皮癣患者和16,881,765名无牛皮癣的对照受试者。纳入的研究有不同程度的协变量调整,因此,他们的发现可能会受到残留的混淆。所有荟萃分析都使用调整后的效应大小,并基于随机效应模型。然而,队列研究与非队列研究(病例对照和横断面研究)分开分析.银屑病和ASCVD之间存在显著关联(队列研究:风险比(HR),1.21;95%置信区间(CI),1.14至1.28;I2=63%;p<0.001;非队列研究:比值比(OR),1.60;95%CI,1.34至1.92;I2=31%;p=0.23)。银屑病也与心肌梗死显著相关(队列研究:HR,1.20;95%CI,1.10~1.31;I2=60%;p<0.001;非队列研究:OR,1.57;95%CI,1.15至2.15;I2=74%;p=0.05),冠状动脉疾病(队列研究:HR,1.20;95%CI,1.13~1.28;I2=67%;p<0.001;非队列研究:OR,1.60;95%CI,1.34至1.92;I2=31%;p=0.23),主动脉瘤(HR,1.45;95%CI,1.04至2.02;I2=67%;p=0.08),但与缺血性卒中无关(HR,1.14;95%CI,0.96至1.36;I2=44%;p=0.17)。就银屑病的严重程度进行汇总分析显示,两者均为轻度(队列研究:HR,1.17;95%CI,1.08~1.26;I2=74%;p<0.001;非队列研究:OR,1.54;95%CI,1.25至1.90;I2=0%;p=0.50)和严重(队列研究:HR,1.43;95%CI,1.23~1.65;I2=65%;p<0.001;非队列研究:OR,1.65;95%CI,1.29~2.12;I2=25%;p=0.26)银屑病与ASCVD显著相关。银屑病(包括轻度和重度疾病)与ASCVD的风险增加有关。包括冠状动脉疾病(CAD)和主动脉瘤(AA)。所有成人银屑病患者应优先考虑ASCVD风险评估和预防。未来的观察性研究调查银屑病和ASCVD之间的关联应该进行更全面的协变量调整。
    Psoriasis is a chronic immune-mediated disease affecting the skin, nails, and/or joints. It is associated with systemic inflammation and may also be linked to an increased risk of atherosclerotic cardiovascular disease (ASCVD). The objectives of this study were to determine the overall risk of ASCVD in patients with psoriasis and to evaluate the risk according to ASCVD type and the severity of psoriasis. This was a systematic review and meta-analysis of observational studies reporting the association between psoriasis and one or more of the clinical types of ASCVD. We searched Medical Literature Analysis and Retrieval System Online (MEDLINE) via PubMed, Excerpta Medica Database (EMBASE), Scopus, Bielefeld Academic Search Engine (BASE), and Google Scholar for relevant studies in the English language from the beginning of their records to July 2023. Study selection and data extraction were conducted by four independent reviewers. A total of 21 observational studies (three cross-sectional, one case-control, and 17 cohort) were included in this review, representing a total of 778,049 patients with psoriasis and 16,881,765 control subjects without psoriasis. The included studies had varying degrees of covariate adjustment, and thus, their findings may have been subject to residual confounding. All the meta-analyses used the adjusted effect sizes and were based on the random-effects model. However, the cohort studies were analysed separately from the non-cohort studies (the case-control and cross-sectional studies). There was a significant association between psoriasis and ASCVD (cohort studies: hazard ratio (HR), 1.21; 95% confidence interval (CI), 1.14 to 1.28; I2 = 63%; p < 0.001; non-cohort studies: odds ratio (OR), 1.60; 95% CI, 1.34 to 1.92; I2 = 31%; p = 0.23). Psoriasis was also significantly associated with myocardial infarction (cohort studies: HR, 1.20; 95% CI, 1.10 to 1.31; I2 = 60%; p < 0.001; non-cohort studies: OR, 1.57; 95% CI, 1.15 to 2.15; I2 = 74%; p = 0.05), coronary artery disease (cohort studies: HR, 1.20; 95% CI, 1.13 to 1.28; I2 = 67%; p < 0.001; non-cohort studies: OR, 1.60; 95% CI, 1.34 to 1.92; I2 = 31%; p = 0.23), aortic aneurysm (HR, 1.45; 95% CI, 1.04 to 2.02; I2 = 67%; p = 0.08) but not with ischaemic stroke (HR, 1.14; 95% CI, 0.96 to 1.36; I2 = 44%; p = 0.17). Pooled analysis in terms of the severity of psoriasis showed that both mild (cohort studies: HR, 1.17; 95% CI, 1.08 to 1.26; I2 = 74%; p < 0.001; non-cohort studies: OR, 1.54; 95% CI, 1.25 to 1.90; I2 = 0%; p = 0.50) and severe (cohort studies: HR, 1.43; 95% CI, 1.23 to 1.65; I2 = 65%; p < 0.001; non-cohort studies: OR, 1.65; 95% CI, 1.29 to 2.12; I2 = 25%; p = 0.26) psoriasis were significantly associated with ASCVD. Psoriasis (including mild and severe disease) is associated with an increased risk of ASCVD, including coronary artery disease (CAD) and aortic aneurysm (AA). ASCVD risk assessment and prevention should be prioritised in all adult psoriasis patients. Future observational studies investigating the association between psoriasis and ASCVD should conduct a more comprehensive adjustment of covariates.

  • 文章类型: Systematic Review
    吸入皮质类固醇(ICS)治疗已被证明可以降低COPD加重的风险。应仅适用于未通过双重长效支气管扩张剂治疗得到充分控制且每年加重≥2次,血液嗜酸性粒细胞计数≥300个细胞/µL的COPD患者。ICS治疗在COPD患者的指南之外广泛使用,使ICS退出成为一个重要的考虑因素。本系统综述旨在对ICS戒断对加重频率的影响进行最新分析。肺功能(FEV1)的变化,并确定停药后恢复ICS治疗的COPD患者的比例。
    纳入比较ICS停药与ICS继续治疗的随机对照试验(RCT)和观察性研究。CochraneCentral,WebofScience,CINHAL,搜索Embase和OVIDMedline。使用CochraneRoB2工具和纽卡斯尔-渥太华量表评估偏倚风险。采用GRADE对随机对照试验进行质量评价。ICS戒断RCT事后分析的荟萃分析,通过血液嗜酸性粒细胞计数(BEC)分层,进行了。
    10项随机对照试验(6642例患者随机分组)和6项观察性研究(160,029例患者)纳入结果。当停用ICS并维持长效支气管扩张剂治疗时,ICS退出试验组和继续试验组的加重频率或肺功能变化无一致差异.这些影响的证据质量中等。对于停药后恢复ICS治疗的患者比例(估计范围为12-93%的参与者),没有足够的证据得出确切的结论。
    COPD患者退出ICS治疗是安全可行的,但应同时维持支气管扩张治疗以获得最佳结果。
    UNASSIGNED: Inhaled corticosteroid (ICS) therapy has been demonstrated to reduce the risk of COPD exacerbations. It should only be prescribed to COPD patients who are not adequately controlled by dual long-acting bronchodilator therapy and who have ≥2 exacerbations per year and a blood eosinophil count ≥300cells/µL. ICS therapy is widely prescribed outside guidelines to COPD patients, making ICS withdrawal an important consideration. This systematic review aims to provide an up-to-date analysis of the effect of ICS withdrawal on exacerbation frequency, change in lung function (FEV1) and to determine the proportion of COPD patients who resume ICS therapy following withdrawal.
    UNASSIGNED: Randomised controlled trials (RCTs) and observational studies which compared ICS withdrawal with ICS continuation treatment were included. Cochrane Central, Web of Science, CINHAL, Embase and OVID Medline were searched. Risk of bias was assessed using the Cochrane RoB2 tool and the Newcastle-Ottawa Scale. Quality assessment of RCTs was conducted using GRADE. Meta-analysis of post-hoc analyses of RCTs of ICS withdrawal, stratified by blood eosinophil count (BEC), was undertaken.
    UNASSIGNED: Ten RCTs (6642 patients randomised) and 6 observational studies (160,029 patients) were included in the results. When ICS was withdrawn and long-acting bronchodilator therapy was maintained, there was no consistent difference in exacerbation frequency or lung function change between the ICS withdrawal and continuation trial arms. The evidence for these effects was of moderate quality. There was insufficient evidence to draw a firm conclusion on the proportion of patients who resumed ICS therapy following withdrawal (estimated range 12-93% of the participants).
    UNASSIGNED: Withdrawal of ICS therapy from patients with COPD is safe and feasible but should be accompanied by maintenance of bronchodilation therapy for optimal outcomes.

    背景:这项探索性综述旨在为劳动力的定义提供经验证据,随机对照试验(RCT)和测量产程时间的观察性研究报告的统计学方法和测量.
    方法:使用不同的数据库进行系统的电子文献检索。设计了一个提取表格,用于提取相关数据。英语,法语,1999年至2019年发表的德国研究也被纳入其中。仅包括将产程(或产程阶段)作为主要结果的RCT和观察性研究。
    结果:92项RCTs和126项观察性研究符合资格。21.7%(n=20)的随机对照试验和23.8%(n=30)的观察性研究没有提供分娩开始的定义。平均值是RCT中最常用的产程测量值(89.1%,n=82),观察性研究的中位数(54.8%,n=69)。大多数RCT(83%,n=76)和观察性研究(70.6%,n=89)使用双变量方法分析产程,t检验是最常用的(45.7%和27%,分别)。只有10.8%(n=10)的RCT和52.4%(n=66)的观察性研究进行了多变量回归:3(30%;10个)RCT和37(56%;66个)观察性研究使用了时间到事件适应模型。
    结论:这项调查报告在如何介绍分娩开始和分娩持续时间阶段方面缺乏共识。关于统计方法,很少有研究使用生存分析,这是分析事件发生时间数据的适当统计框架。
    BACKGROUND: This exploratory review aimed to provide empirical evidence on the definitions of labor, the statistical approaches and measures reported in randomized controlled trials (RCTs) and observational studies measuring the duration of labor.
    METHODS: A systematic electronic literature search was conducted using different databases. An extraction form was designed and used to extract relevant data. English, French, and German studies published between 1999 and 2019 have been included. Only RCTs and observational studies analyzing labor duration (or a phase of labor duration) as a primary outcome have been included.
    RESULTS: Ninety-two RCTs and 126 observational studies were eligible. No definition of the onset of labor was provided in 21.7% (n = 20) of the RCTs and 23.8% (n = 30) of the observational studies. Mean was the most frequently applied measure of labor duration in the RCTs (89.1%, n = 82), and median in the observational studies (54.8%, n = 69). Most RCTs (83%, n = 76) and observational studies (70.6%, n = 89) analyzed labor duration using a bivariate method, with the t-test being the most frequently applied (45.7% and 27%, respectively). Only 10.8% (n = 10) of the RCTs and 52.4% (n = 66) of the observational studies conducted a multivariable regression: 3 (30%; out of 10) RCTs and 37 (56%; out of 66) observational studies used a time-to-event adapted model.
    CONCLUSIONS: This survey reports a lack of agreement with respect to how the onset of labor and phases of labor duration are presented. Concerning the statistical approaches, few studies used survival analysis, which is the appropriate statistical framework to analyze time-to-event data.

    背景:对生长活跃的患者进行准确评估对于纠正骨骼错牙合畸形至关重要。颈椎成熟(CVM)分期很容易,没有不必要的辐射,但是它的观察者之间和观察者之间的协议仍然存在争议。
    目的:本研究旨在评估CVM分期的观察者之间(可靠性)和观察者之间的一致性(可重复性)。
    方法:截至2023年10月,对五个数据库进行了全面的文献检索。纳入标准包括观察性研究,这些研究特别报道了内部评分者,评估者之间,或两者的协议作为他们的颈椎成熟(CVM)分期的主要目标。样本量超过15名参与者的研究被考虑纳入。重复研究选择后,数据提取,和偏见风险评估,进行了kappa(k)/相关系数(r)及其95%置信区间(CI)的随机效应荟萃分析,其次是元回归,敏感性分析,和亚组分析。
    结果:纳入了17项观察性研究(包括1437例侧头颅图和110名评估者)。可靠性(8项研究;k=0.62[95%CI:0.44,0.78])和可重复性(9项研究;k=0.708[95%CI:0.59,0.82])是相当大的。观察者间相关性几乎是完美的(在9项研究中,r=0.86[95%CI:0.82,0.89]),而观察者内相关性是实质性的(在2项研究中,r=0.75[95%CI:0.62,0.84])。侧位头图的追踪显着提高了观察者间的可靠性(β=0.29[0.57,0.0031]),但裁剪和评估时间(初始与随访)无显著影响。高质量研究的可靠性(P<0.001)和可重复性(P=0.049)优于低质量研究。
    结论:CVM分期的评估是准确的,可重复达到令人满意的水平。CVM的准确性和可重复性在使用追踪的头颅图和那些具有低偏倚风险的研究中更高。

    BACKGROUND: The accurate assessment of active growth is pivotal for the correction of skeletal malocclusion in growing patients. Cervical vertebral maturation (CVM) staging is easy and devoid of unnecessary radiation, but its inter- and intra-observer agreement is still debatable.
    OBJECTIVE: This study aims to assess inter-observer (reliability) and intra-observer agreement (reproducibility) for CVM staging.
    METHODS: A comprehensive literature search across five databases up to October 2023 was conducted. Inclusion criteria comprised observational studies that specifically reported intra-rater, inter-rater, or both agreements as their primary objectives for cervical vertebral maturation (CVM) staging. Studies with a sample size exceeding 15 participants were considered for inclusion. After duplicate study selection, data extraction, and risk-of-bias assessment, random-effects meta-analyses of kappa (k)/correlation coefficient (r) and their 95% confidence intervals (CIs) were performed, followed by meta-regressions, sensitivity analyses, and subgroup analyses.
    RESULTS: Seventeen observational studies (comprising 1437 lateral cephalograms and 110 assessors) were included. The reliability (8 studies; k=0.62 [95% CI: 0.44, 0.78]) and reproducibility (9 studies; k=0.708 [95% CI: 0.59, 0.82]) were substantial. The inter-observer correlation was almost perfect (in 9 studies; r=0.86 [95% CI: 0.82, 0.89]) while intra-observer correlation was substantial (in 2 studies; r=0.75 [95% CI: 0.62, 0.84]). Tracing of lateral cephalograms significantly increased inter-observer reliability (β=0.29 [0.57, 0.0031]) but cropping and time of assessment (initial vs. follow-up) had no significant impact. The reliability (P<0.001) and reproducibility (P=0.049) of high-quality studies were superior to those observed in low-quality studies.
    CONCLUSIONS: Assessment of the CVM staging is accurate and reproducible to a satisfactory level. The accuracy and reproducibility of CVM are higher in studies utilizing traced cephalograms and those with a low-risk of bias.

    BACKGROUND: Vitiligo is a disease that affects people of all skin shades and can impact their quality of life. Reliable evidence on the effectiveness and adverse events associated with the recent use of Janus kinase (JAK) inhibitors to treat vitiligo is needed. This protocol for a systematic review and meta-analysis seeks to collect evidence from both randomized controlled trials (RCTs) and observational studies to determine the effectiveness and patient-centered outcomes concerning treatment with JAK inhibitors.
    METHODS: We will conduct a systematic review of the literature for RCTs and observational studies that used upadacitinib, ritlecitinib, brepocitinib, ifidancitinib, cerdulatinib, deglocitinib, baricitinib, tofacitinib, and ruxolitinib JAK inhibitors as treatments for vitiligo compared to placebo, no treatment, or combination therapies. We will systematically search from inception in Epistemonikos, MEDLINE, Scopus, Cochrane Central Register of Controlled Trials, EMBASE, ClinicalTrials.gov, PsycINFO, Allied and Complementary Medicine Database, Latin American and Caribbean Health Sciences Literature, Web of Science Core Collection, relevant preprint servers, and the gray literature. Ethics approval was not sought as the protocol and systematic review will not involve human participants, but rather summarized and anonymous data from studies. Primary outcomes include quality of life, percentage repigmentation, decreased vitiligo within 1 year or more, lasting repigmentation after a 2-year follow-up, cosmetic acceptability of repigmentation and tolerability or burden of treatment, and adverse events. Secondary outcomes are patient and study characteristics. We will include full-text articles, preprints, and clinical trial data in any language and all geographic regions. For data sources unavailable in English, we will obtain translations from global collaborators via the Cochrane Engage network. We will exclude articles for which sufficient information cannot be obtained from the authors of articles and systematic reviews. At least two investigators will independently assess articles for inclusion and extract data; reliability will be assessed before subsequent selection and data extraction of remaining studies. The risk of bias and certainty of evidence with Grading of Recommendations Assessment, Development, and Evaluation guidelines will be assessed independently by at least two investigators. We will estimate treatment effects by random-effects meta-analyses and assess heterogeneity using I2. Data that cannot be included in the meta-analysis will be reported narratively using themes.
    CONCLUSIONS: The proposed systematic review and meta-analysis describe the methods for summarizing and synthesizing the evidence on the effectiveness and patient-centered outcomes concerning the treatment of vitiligo with JAK inhibitors that were recently approved for this indication. To disseminate further the results of our systematic review, we plan to present them at international conferences and meetings. Our findings will provide robust evidence to facilitate decision-making at the policy or practitioner level.

    目的:外周动脉疾病(PAD)的诊断通常适用于下肢动脉粥样硬化阻塞的相关症状,尽管其临床表现范围从踝臂指数异常到严重的肢体缺血。随后,PAD的治疗和预后随疾病分期而变化。一个关键方面是如何在基于行政数据库的研究中解决这种差异,这些研究依赖于诊断代码进行病例识别。TheobjectiveofthisscopingreviewistoinventorytheidentificationstrategiesusedinstudiesonPADthatrelyonadministrativedatabases,映射所应用的ICD代码的利弊,并提出行政数据库中案件识别共识框架的第一个大纲。
    方法:通过系统的PubMed搜索确定了2010年至2021年之间发布的基于注册表的报告。根据明确的研究重点对研究进行了细分:跛行,严重肢体缺血,或一般外周动脉疾病和用于病例识别的ICD代码。
    结果:确定了90项研究,其中36(40%)未指定所研究的PAD等级。研究了49篇(54%)文章指定了PAD等级。五篇(6%)文章在方法和基线人口统计中指定了不同的PAD亚组,但不是在进一步的分析中。用于病例识别的ICD代码映射指定了所研究的PAD等级的研究表明了显着的异质性,重叠,和不一致。
    结论:大部分基于注册登记的PAD研究未能确定研究重点。此外,在报告重点的研究中,不一致的策略用于PAD病例识别。这些发现挑战了研究的有效性,并干扰研究间的比较。这项范围界定审查为PAD行政研究中标准化病例选择的共识框架提供了第一个倡议。预计更统一的编码将提高研究的有效性,并促进研究间的比较。
    BACKGROUND: The diagnosis of peripheral arterial disease (PAD) is commonly applied for symptoms related to atherosclerotic obstructions in the lower extremity, though its clinical manifestations range from an abnormal ankle-brachial index to critical limb ischemia. Subsequently, management and prognosis of PAD vary widely with the disease stage. A critical aspect is how this variation is addressed in administrative database-based studies that rely on diagnosis codes for case identification. The objective of this scoping review is to inventory the identification strategies used in studies on PAD that rely on administrative databases, to map the pros and cons of the International Classification of Diseases (ICD) codes applied, and to propose a first outline for a consensus framework for case identification in administrative databases.
    METHODS: Registry-based reports published between 2010 and 2021 were identified through a systematic PubMed search. Studies were subcategorized on the basis of the expressed study focus: claudication, critical limb ischemia, or general peripheral arterial disease, and the ICD code(s) applied for case identification mapped.
    RESULTS: Ninety studies were identified, of which 36 (40%) did not specify the grade of PAD studied. Forty-nine (54%) articles specified PAD grade studied. Five (6%) articles specified different PAD subgroups in methods and baseline demographics, but not in further analyses. Mapping of the ICD codes applied for case identification for studies that specified the PAD grade studied indicated a remarkable heterogeneity, overlap, and inconsistency.
    CONCLUSIONS: A large proportion of registry-based studies on PAD fail to define the study focus. In addition, inconsistent strategies are used for PAD case identification in studies that report a focus. These findings challenge study validity and interfere with inter-study comparison. This scoping review provides a first initiative for a consensus framework for standardized case selection in administrative studies on PAD. It is anticipated that more uniform coding will improve study validity and facilitate inter-study comparisons.

    本次范围界定审查的目的是评估被认为与北欧和波罗的海国家相关的酒精消费和健康结果的最新证据,包括心血管疾病,癌症,和全因死亡率。它基于2012年之前的北欧营养建议和2021年5月31日之前发表的相关论文。目前主要来自观察性流行病学研究的证据表明,适度饮酒可能对心肌梗死(MI)和2型糖尿病具有保护作用.孟德尔随机化分析并不完全支持这些发现,可能是因为这些分析可能无法识别低酒精摄入量。对于几种癌症,不可能设置任何安全限制。在不暴饮暴食的中老年人中,轻度至中度饮酒不会增加全因死亡率。在年轻人中,完全禁欲与最低的死亡风险相关。关于饮酒的观察研究受到一些固有的方法论问题的阻碍,例如确定酒精摄入量,选择适当的暴露组,以及对混杂变量的控制不足,对撞机,和调解员。还应该强调的是,对酒精健康轴的社会经济贡献在较低的社会阶层中具有更强的酒精有害影响。上述问题导致了解开酒精之间因果网的复杂性,调解员,混杂因素,和健康结果。
    The objective of this scoping review is to evaluate the updated evidence on the consumption of alcohol and health outcomes regarded as relevant for the Nordic and Baltic countries, including cardiovascular disease, cancer, and all-cause mortality. It is based on the previous Nordic Nutrition Recommendations of 2012 and relevant papers published until 31 May 2021. Current evidence from mainly observational epidemiological studies suggests that regular, moderate alcohol consumption may confer protective effects against myocardial infarction (MI) and type 2 diabetes. Mendelian randomization analyses do not fully support these findings, possibly because these analyses may fail to identify low alcohol intake. For several cancers, it is not possible to set any safe limit. All-cause mortality is not increased with light to moderate alcohol intake in middle-aged and older adults who do not engage in binge drinking. Total abstinence is associated with the lowest risk of mortality in young adults. Observational studies on alcohol consumption are hampered by a number of inherent methodological issues such as ascertainment of alcohol intake, selection of appropriate exposure groups, and insufficient control of confounding variables, colliders, and mediators. It should also be emphasized that there is a socio-economic contribution to the alcohol-health axis with a stronger detrimental effect of alcohol in the lower social classes. The above issues contribute to the complexity of unravelling the causal web between alcohol, mediators, confounders, and health outcome.

    背景:肝细胞癌(HCC)是一种发病率和死亡率不断增加的疾病,尤其是慢性病毒性肝炎患者。研究表明,阿司匹林可以降低肝癌的发病率;然而,病毒性肝炎患者的获益程度尚不清楚.这项研究的重点是阿司匹林使用与慢性病毒性肝炎患者肝癌风险之间的关系。
    方法:对PubMed的系统搜索,Embase,WebofScience,Cochrane图书馆数据库从最早的可用日期到2023年12月16日进行。主要结果是HCC发病率,次要结局是消化道出血.结果表示为风险比(HR)和95%置信区间(CI)。根据通过I2统计量评估的异质性,使用随机或固定效应模型进行荟萃分析。
    结果:共有13篇文章(303,414名参与者和14,423名HCC患者)被纳入分析。阿司匹林使用者的HCC发生率低于非阿司匹林使用者(HR0.75;95%CI,0.68-0.83;P<0.001;I2=90.0%)。亚组分析进一步表明,这种效应可能在HCV患者中更为明显,非肝硬化患者,他汀类药物患者,和长期服用阿司匹林的人,但可能有消化道出血的风险(HR1.13;95%CI,1.07-1.20;P=0.906;I2=0.0%).
    结论:我们的荟萃分析显示,在慢性病毒性肝炎患者中,阿司匹林的使用与肝癌的风险显着降低有关,但是要注意消化道出血的可能风险,这一结论需要在未来进一步验证。
    BACKGROUND: Hepatocellular carcinoma (HCC) is a disease demonstrating increasing morbidity and mortality, especially in patients with chronic viral hepatitis. Studies have shown that aspirin can reduce the incidence of liver cancer; however, the degree of benefit in patients with viral hepatitis is unclear. This study focused on the association between aspirin use and HCC risk in patients with chronic viral hepatitis.
    METHODS: A systematic search of the PubMed, Embase, Web of Science, and Cochrane Library databases was performed from the earliest available date to December 16, 2023. The primary outcome was HCC incidence, and the secondary outcome was gastrointestinal bleeding. The results were expressed as hazard ratios (HRs) and 95% confidence intervals (CIs). Meta-analyses were performed by using random or fixed-effects models based on the heterogeneity assessed via the I2 statistic.
    RESULTS: A total of 13 articles (303,414 participants and 14,423 HCC patients) were included in the analysis. The incidence of HCC in aspirin users was lower than that in non-aspirin users (HR 0.75; 95% CI, 0.68-0.83; P < 0.001; I2 = 90.0%). Subgroup analysis further showed that this effect may be more obvious in HCV patients, non-cirrhotic patients, patients with statins, and long-term aspirin users, but it may have the risk of gastrointestinal bleeding (HR 1.13; 95% CI, 1.07-1.20; P = 0.906; I2 = 0.0%).
    CONCLUSIONS: Our meta-analysis shows that in patients with chronic viral hepatitis, aspirin use is associated with a significantly reduced risk of liver cancer, but attention should be paid to the possible risk of gastrointestinal bleeding, and this conclusion needs further validation in the future.

    背景:随机对照试验和现实世界研究表明,钠-葡萄糖转运蛋白2抑制剂(SGLT2is)和胰高血糖素样肽-1受体激动剂(GLP-1RAs)的联合治疗与空腹血糖(FPG)的改善有关。糖化血红蛋白(HbA1c),收缩压(SBP),体重指数(BMI),和总胆固醇水平。然而,对现有的真实世界证据进行系统评价可能有助于在真实世界中做出临床决策.这项荟萃分析评估了SGLT2isGLP-1RA组合的安全性和有效性,重点是在现实世界中2型糖尿病(T2DM)患者的心脏保护作用以及降糖能力。
    方法:在PubMed/MEDLINE中进行电子搜索,PROQuest,Scopus,CINAHL,和谷歌学者数据库。分别使用JoannaBriggs研究所SUMARI软件包和ReviewManagerv5.4进行定性分析和荟萃分析。
    结果:最初的数据库搜索产生了1445篇文章;其中,13人被纳入本研究。分析表明,与单独治疗相比,SGLT2is+GLP-1RAs组合与全因死亡率显著降低相关(比值比[95%置信区间[CI]0.49[0.41,0.60];p<0.00001)。BMI显着降低(-1.71[-2.74,-0.67];p=0.001),SBP(-6.35[-10.17,-2.53];p=0.001),HbA1c水平(-1.48[-1.75,-1.21];p<0.00001),和FPG(-2.27[-2.78,-1.76];p<0.00001)与同时施用联合用药相关。总胆固醇水平的变化以及同时和序贯联合治疗对该结果的差异并不显著。
    结论:这项基于现实世界数据的系统评价和荟萃分析表明,SGLT2is+GLP-1RAs的组合与更低的全因死亡率和心血管疾病的有利改善有关。肾,和血糖测量。这些发现推动了行动呼吁,将这种组合早期和同时纳入T2DM患者的管理,并实现潜在的心血管益处和肾脏保护。
    BACKGROUND: Randomized controlled trials and real-world studies suggest that combination therapy with sodium-glucose transport protein 2 inhibitors (SGLT2is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) is associated with improvement in fasting plasma glucose (FPG), glycated hemoglobin (HbA1c), systolic blood pressure (SBP), body mass index (BMI), and total cholesterol levels. However, a systematic review of available real-world evidence may facilitate clinical decision-making in the real-world scenario. This meta-analysis assessed the safety and effectiveness of combinations of SGLT2is + GLP-1RAs with a focus on their cardioprotective effects along with glucose-lowering ability in patients with type 2 diabetes mellitus (T2DM) in a real-world setting.
    METHODS: Electronic searches were performed in the PubMed/MEDLINE, PROQuest, Scopus, CINAHL, and Google Scholar databases. Qualitative analyses and meta-analyses were performed using the Joanna Briggs Institute SUMARI software package and Review Manager v5.4, respectively.
    RESULTS: The initial database search yielded 1445 articles; of these, 13 were included in this study. The analyses indicated that SGLT2is + GLP-1RAs combinations were associated with significantly lower all-cause mortality when compared with individual therapies (odds ratio [95% confidence interval [CI] 0.49 [0.41, 0.60]; p < 0.00001). Significant reductions in BMI (- 1.71 [- 2.74, - 0.67]; p = 0.001), SBP (- 6.35 [- 10.17, - 2.53]; p = 0.001), HbA1c levels (- 1.48 [- 1.75, - 1.21]; p < 0.00001), and FPG (- 2.27 [- 2.78, - 1.76]; p < 0.00001) were associated with the simultaneous administration of the combination. Changes in total cholesterol levels and differences between simultaneous and sequential combination therapies for this outcome were not significant.
    CONCLUSIONS: This systematic review and meta-analysis based on real-world data suggests that the combination of SGLT2is + GLP-1RAs is associated with lower all-cause mortality and favorable improvements in cardiovascular, renal, and glycemic measurements. The findings drive a call-to-action to incorporate this combination early and simultaneously in managing T2DM patients and achieve potential cardiovascular benefits and renal protection.

    目的:胃裂的病因被认为是多因素的。我们进行了系统评价和荟萃分析,以评估是否在怀孕期间使用药物,与后代腹裂的风险有关。
    方法:PubMed,EMBASE,我们从1990年1月1日至2020年12月31日对Scopus进行了检索,以确定观察性研究,这些研究检查了妊娠期药物使用与腹裂风险之间的关系.Newcastle-Ottawa量表用于个体研究的质量评估。我们使用随机效应模型汇总调整后的测量值,以估计相对风险[RR]和95%置信区间[CI]。计算异质性和发表偏倚的I2统计量。
    结果:提供751,954例妊娠数据的18项研究纳入荟萃分析。汇总的RR显示阿司匹林之间存在显着关联(RR1.66,95%CI1.16-2.38;I2=58.3%),口服避孕药(RR1.52,95%CI1.21-1.92;I2=22.0%),伪麻黄碱和苯丙醇胺(RR1.51,95%CI1.16-1.97;I2=33.2%),布洛芬(RR1.42,95%CI1.26-1.60;I2=0.0%),和胃裂。在扑热息痛和腹裂之间未观察到相关性(RR1.16,95%CI0.96-1.41;I2=39.4%)。
    结论:这些结果表明,在怀孕的头三个月暴露于非处方药(OTC),如阿司匹林,布洛芬,伪麻黄碱和苯丙醇胺以及口服避孕药,与腹裂的风险增加有关。然而,这些关联仅在由地理位置定义的特定子组中才是重要的,调整变量和控制类型。因此,需要进一步的研究来调查它们是胃裂的潜在危险因素,评估其在怀孕期间的安全性,并制定治疗策略以降低后代腹裂的风险。PROSPERO注册号:CRD42021287529。
    OBJECTIVE: The aetiology of gastroschisis is considered multifactorial. We conducted a systematic review and meta-analysis to assess whether the use of medications during pregnancy, is associated with the risk of gastroschisis in offspring.
    METHODS: PubMed, EMBASE, and Scopus were searched from 1st January 1990 to 31st December 2020 to identify observational studies examining the association between medication use during pregnancy and the risk of gastroschisis. The Newcastle-Ottawa Scale was used for the quality assessment of the individual studies. We pooled adjusted measures using a random-effect model to estimate relative risk [RR] and the 95% confidence interval [CI]. I2 statistic for heterogeneity and publication bias was calculated.
    RESULTS: Eighteen studies providing data on 751,954 pregnancies were included in the meta-analysis. Pooled RRs showed significant associations between aspirin (RR 1.66, 95% CI 1.16-2.38; I2 = 58.3%), oral contraceptives (RR 1.52, 95% CI 1.21-1.92; I2 = 22.0%), pseudoephedrine and phenylpropanolamine (RR 1.51, 95% CI 1.16-1.97; I2 = 33.2%), ibuprofen (RR 1.42, 95% CI 1.26-1.60; I2 = 0.0%), and gastroschisis. No association was observed between paracetamol and gastroschisis (RR 1.16, 95% CI 0.96-1.41; I2 = 39.4%).
    CONCLUSIONS: These results suggest that the exposure in the first trimester of pregnancy to over the counter medications (OTC) such as aspirin, ibuprofen, pseudoephedrine and phenylpropanolamine as well as to oral contraceptives, was associated with an increased risk of gastroschisis. However, these associations are significant only in particular subgroups defined by geographic location, adjustment variables and type of control. Therefore, further research is needed to investigate them as potential risk factors for gastroschisis, to assess their safety in pregnancy and to develop treatment strategies to reduce the risk of gastroschisis in offspring.
