    背景:血浆致动脉粥样硬化指数(AIP)是一种非传统的脂质参数,可以反映动脉粥样硬化的负担。怀孕期间出现类似动脉粥样硬化的脂质分布。尽管脂质代谢在糖尿病发病机制中至关重要,没有证据表明AIP与妊娠期糖尿病(GDM)有关.因此,我们的目的是探讨AIP与GDM之间的关系,并评估AIP对GDM的预测能力.
    方法:这是一项基于来自韩国585名单身孕妇的前瞻性队列研究数据的二次分析。AIP计算为log10(TG/HDL)。我们使用逻辑回归模型检查了AIP和GDM之间的关系,曲线拟合,敏感性分析,和亚组分析。还使用接收器工作特性(ROC)分析来确定AIP预测GDM的能力。
    结果:参与者的平均年龄为32.06±3.76岁。AIP平均为0.24±0.20。GDM发生率为6.15%。在调整了潜在的混杂变量后,AIP与GDM呈正线性关系(P为非线性:0.801,OR1.58,95%CI1.27~1.97)。敏感性分析和亚组分析证明了AIP和GDM之间联系的稳健性。ROC曲线下面积为0.7879(95%CI0.7087-0.8671)表明AIP是GDM的出色预测指标。特异性为75.41%,灵敏度为72.22%,鉴别GDM的理想AIP临界值为0.3557。
    结论:这项研究表明,妊娠10-14周的AIP与GDM风险呈独立正相关。AIP可以作为GDM高危孕妇的早期筛查和监测工具,从而优化GDM预防策略。
    背景:ClinicalTrials.gov注册号。NCT02276144。
    BACKGROUND: Atherogenic index of plasma (AIP) is a non-traditional lipid parameter that can reflect the burden of atherosclerosis. A lipid profile resembling atherosclerosis emerged during pregnancy. Although lipid metabolism is pivotal in diabetes pathogenesis, there is no evidence linking AIP to gestational diabetes mellitus (GDM). Therefore, our objective was to explore the relationship between AIP and GDM and assess AIP\'s predictive capability for GDM.
    METHODS: This was a secondary analysis based on data from a prospective cohort study in Korea involving 585 single pregnant women. AIP was calculated as log10 (TG/HDL). We examined the relationship between AIP and GDM using logistic regression models, curve fitting, sensitivity analyses, and subgroup analyses. Receiver operating characteristic (ROC) analysis was also used to determine the ability of AIP to predict GDM.
    RESULTS: The average age of the participants was 32.06 ± 3.76 years. The AIP was 0.24 ± 0.20 on average. The GDM incidence was 6.15%. After adjustment for potentially confounding variables, AIP showed a positive linear relationship with GDM (P for non-linearity: 0.801, OR 1.58, 95% CI 1.27-1.97). The robustness of the connection between AIP and GDM was demonstrated by sensitivity analyses and subgroup analyses. An area under the ROC curve of 0.7879 (95% CI 0.7087-0.8671) indicates that AIP is an excellent predictor of GDM. With a specificity of 75.41% and sensitivity of 72.22%, the ideal AIP cut-off value for identifying GDM was 0.3557.
    CONCLUSIONS: This study revealed that the AIP at 10-14 weeks of gestation was independently and positively correlated with GDM risk. AIP could serve as an early screening and monitoring tool for pregnant women at high risk of GDM, thereby optimizing GDM prevention strategies.
    BACKGROUND: ClinicalTrials.gov registration no. NCT02276144.

    This study aimed to identify hub genes and elucidate the molecular mechanisms underlying low bone mineral density (BMD) in perimenopausal women. R software was used to normalize the dataset and screen the gene set associated with BMD in perimenopausal women from the Gene Expression Omnibus database. Cytoscape software was used to identify 7 critical genes. Gene enrichment analysis and protein interaction was employed to further analyze the core genes, and the CIBERSORT deconvolution algorithm was used to perform immune infiltration analysis of 22 immune genes in the samples. Furthermore, an analysis of the immune correlations of 7 crucial genes was conducted. Subsequently, a receiver operating characteristic curve was constructed to assess the diagnostic efficacy of these essential genes. A total of 171 differentially expressed genes were identified that were primarily implicated in the signaling pathways associated with apoptosis. Seven crucial genes (CAMP, MMP8, HMOX1, CTNNB1, ELANE, AKT1, and CEACAM8) were effectively filtered. The predominant functions of these genes were enriched in specific granules. The pivotal genes displayed robust associations with activated dendritic cells. The developed risk model showed a remarkable level of precision, as evidenced by an area under the curve of 0.8407 and C-index of 0.854. The present study successfully identified 7 crucial genes that are significantly associated with low BMD in perimenopausal women. Consequently, this research offers a solid theoretical foundation for clinical risk prediction, drug sensitivity analysis, and the development of targeted drugs specifically tailored for addressing low BMD in perimenopausal women.

    背景:已经报道了代谢状态和代谢变化与心血管结局风险之间的关联。然而,遗传易感性在这些关联背后的作用仍未被探索.我们的目的是检查代谢状态,代谢转变,和遗传易感性共同影响不同体重指数(BMI)类别的心血管结局和全因死亡率.
    方法:在我们对英国生物库的分析中,基线时,我们共纳入481,576名参与者(平均年龄:56.55岁;男性:45.9%).代谢健康(MH)状态定义为存在<3个异常成分(腰部情况、血压,血糖,甘油三酯,和高密度脂蛋白胆固醇)。正常体重,超重,肥胖定义为18.5≤BMI<25kg/m2,25≤BMI<30kg/m2,BMI≥30kg/m2。使用多基因风险评分(PRS)估计遗传易感性。进行Cox回归以评估代谢状态的关联,代谢转变,和PRS与不同BMI类别的心血管结局和全因死亡率。
    结果:在14.38年的中位随访中,31,883(7.3%)全因死亡,8133例(1.8%)心血管疾病(CVD)死亡,记录了67,260例(14.8%)CVD病例。在那些具有高PRS的人中,与代谢不健康的肥胖人群相比,代谢健康超重人群的全因死亡率(风险比[HR]0.70;95%置信区间[CI]0.65,0.76)和CVD死亡率(HR0.57;95%CI0.50,0.64)风险最低。在中度和低度PRS组中,有益的关联似乎更大。代谢健康正常体重的个体患CVD的风险最低(HR0.54;95%CI0.51,0.57)。此外,不同BMI类别的代谢状态和PRS与心血管结局和全因死亡率的负相关在65岁以下的个体中更为显著(P交互作用<0.05).此外,在BMI类别中,观察到代谢转变和PRS对这些结局的综合保护作用.
    结论:MH状态和低PRS与所有BMI类别的不良心血管结局和全因死亡率的较低风险相关。这种保护作用在65岁以下的个体中尤其明显。需要进一步的研究来确认不同人群的这些发现,并调查所涉及的潜在机制。
    BACKGROUND: Associations between metabolic status and metabolic changes with the risk of cardiovascular outcomes have been reported. However, the role of genetic susceptibility underlying these associations remains unexplored. We aimed to examine how metabolic status, metabolic transitions, and genetic susceptibility collectively impact cardiovascular outcomes and all-cause mortality across diverse body mass index (BMI) categories.
    METHODS: In our analysis of the UK Biobank, we included a total of 481,576 participants (mean age: 56.55; male: 45.9%) at baseline. Metabolically healthy (MH) status was defined by the presence of < 3 abnormal components (waist circumstance, blood pressure, blood glucose, triglycerides, and high-density lipoprotein cholesterol). Normal weight, overweight, and obesity were defined as 18.5 ≤ BMI < 25 kg/m2, 25 ≤ BMI < 30 kg/m2, and BMI ≥ 30 kg/m2, respectively. Genetic predisposition was estimated using the polygenic risk score (PRS). Cox regressions were performed to evaluate the associations of metabolic status, metabolic transitions, and PRS with cardiovascular outcomes and all-cause mortality across BMI categories.
    RESULTS: During a median follow-up of 14.38 years, 31,883 (7.3%) all-cause deaths, 8133 (1.8%) cardiovascular disease (CVD) deaths, and 67,260 (14.8%) CVD cases were documented. Among those with a high PRS, individuals classified as metabolically healthy overweight had the lowest risk of all-cause mortality (hazard ratios [HR] 0.70; 95% confidence interval [CI] 0.65, 0.76) and CVD mortality (HR 0.57; 95% CI 0.50, 0.64) compared to those who were metabolically unhealthy obesity, with the beneficial associations appearing to be greater in the moderate and low PRS groups. Individuals who were metabolically healthy normal weight had the lowest risk of CVD morbidity (HR 0.54; 95% CI 0.51, 0.57). Furthermore, the inverse associations of metabolic status and PRS with cardiovascular outcomes and all-cause mortality across BMI categories were more pronounced among individuals younger than 65 years (Pinteraction < 0.05). Additionally, the combined protective effects of metabolic transitions and PRS on these outcomes among BMI categories were observed.
    CONCLUSIONS: MH status and a low PRS are associated with a lower risk of adverse cardiovascular outcomes and all-cause mortality across all BMI categories. This protective effect is particularly pronounced in individuals younger than 65 years. Further research is required to confirm these findings in diverse populations and to investigate the underlying mechanisms involved.

    背景:尽管这项研究具有回顾性性质,我们已经在中国临床试验注册中心进行了主动注册.注册号为ChiCTR2200062210,注册日期为29/07/2022。
    BACKGROUND: Transfer to the ICU is common following non-cardiac surgeries, including radical colorectal cancer (CRC) resection. Understanding the judicious utilization of costly ICU medical resources and supportive postoperative care is crucial. This study aimed to construct and validate a nomogram for predicting the need for mandatory ICU admission immediately following radical CRC resection.
    METHODS: Retrospective analysis was conducted on data from 1003 patients who underwent radical or palliative surgery for CRC at Ningxia Medical University General Hospital from August 2020 to April 2022. Patients were randomly assigned to training and validation cohorts in a 7:3 ratio. Independent predictors were identified using the least absolute shrinkage and selection operator (LASSO) and multivariate logistic regression in the training cohort to construct the nomogram. An online prediction tool was developed for clinical use. The nomogram\'s calibration and discriminative performance were assessed in both cohorts, and its clinical utility was evaluated through decision curve analysis (DCA).
    RESULTS: The final predictive model comprised age (P = 0.003, odds ratio [OR] 3.623, 95% confidence interval [CI] 1.535-8.551); nutritional risk screening 2002 (NRS2002) (P = 0.000, OR 6.129, 95% CI 2.920-12.863); serum albumin (ALB) (P = 0.013, OR 0.921, 95% CI 0.863-0.982); atrial fibrillation (P = 0.000, OR 20.017, 95% CI 4.191-95.609); chronic obstructive pulmonary disease (COPD) (P = 0.009, OR 8.151, 95% CI 1.674-39.676); forced expiratory volume in 1 s / Forced vital capacity (FEV1/FVC) (P = 0.040, OR 0.966, 95% CI 0.935-0.998); and surgical method (P = 0.024, OR 0.425, 95% CI 0.202-0.891). The area under the curve was 0.865, and the consistency index was 0.367. The Hosmer-Lemeshow test indicated excellent model fit (P = 0.367). The calibration curve closely approximated the ideal diagonal line. DCA showed a significant net benefit of the predictive model for postoperative ICU admission.
    CONCLUSIONS: Predictors of ICU admission following radical CRC resection include age, preoperative serum albumin level, nutritional risk screening, atrial fibrillation, COPD, FEV1/FVC, and surgical route. The predictive nomogram and online tool support clinical decision-making for postoperative ICU admission in patients undergoing radical CRC surgery.
    BACKGROUND: Despite the retrospective nature of this study, we have proactively registered it with the Chinese Clinical Trial Registry. The registration number is ChiCTR2200062210, and the date of registration is 29/07/2022.

    尽管手术技术有了进步,感染性心内膜炎(IE)的手术死亡率仍然相对较高.这项研究的目的是建立一个列线图模型,以根据术前临床特征预测感染性心内膜炎心脏手术患者的术后早期死亡率。
    我们回顾性分析了2007年1月至2023年6月在我们中心接受手术的357例IE患者的临床资料。使用单变量和多变量逻辑回归模型确定术后早期死亡的独立危险因素。基于这些因素,建立了一个预测模型,并在列线图中呈现。通过受试者工作特性(ROC)曲线评估列线图的性能,校准图,和决策曲线分析(DCA)。利用自举方法执行内部验证。
    列线图包括9个预测因子:年龄,中风,肺栓塞,白蛋白水平,心功能IV级,抗生素使用<4周,植被大小≥1.5厘米,瓣膜周围脓肿和术前透析。模型ROC曲线下面积(AUC)为0.88(95CI:0.80-0.96)。校准图表明列线图具有良好的预测一致性,具有令人满意的Hosmer-Lemeshow测试结果(χ2=13.490,p=0.142)。决策曲线分析表明,与“全部操作”或“无操作”策略相比,列线图模型提供了更大的临床净收益。
    创新的列线图模型为心血管外科医师提供了一种工具来预测IE手术患者术后早期死亡的风险。该模型可为IE患者的术前决策提供有价值的参考,并可提高IE患者的临床结局。
    UNASSIGNED: Despite advancements in surgical techniques, operations for infective endocarditis (IE) remain associated with relatively high mortality. The aim of this study was to develop a nomogram model to predict the early postoperative mortality in patients undergoing cardiac surgery for infective endocarditis based on the preoperative clinical features.
    UNASSIGNED: We retrospectively analyzed the clinical data of 357 patients with IE who underwent surgeries at our center between January 2007 and June 2023. Independent risk factors for early postoperative mortality were identified using univariate and multivariate logistic regression models. Based on these factors, a predictive model was developed and presented in a nomogram. The performance of the nomogram was evaluated through the receiver operating characteristic (ROC) curve, calibration plot, and decision curve analysis (DCA). Internal validation was performed utilizing the bootstrapping method.
    UNASSIGNED: The nomogram included nine predictors: age, stroke, pulmonary embolism, albumin level, cardiac function class IV, antibotic use <4weeks, vegetation size ≥1.5 cm, perivalvular abscess and preoperative dialysis. The area under the ROC curve (AUC) of the model was 0.88 (95%CI:0.80-0.96). The calibration plot indicated strong prediction consistency of the nomogram with satisfactory Hosmer-Lemeshow test results (χ2 = 13.490, p = 0.142). Decision curve analysis indicated that the nomogram model provided greater clinical net benefits compared to \"operate-all\" or \"operate-none\" strategies.
    UNASSIGNED: The innovative nomogram model offers cardiovascular surgeons a tool to predict the risk of early postoperative mortality in patients undergoing IE operations. This model can serve as a valuable reference for preoperative decision-making and can enhance the clinical outcomes of IE patients.

    Objectives.临时机械循环支持(TMCS)已成为治疗心源性休克的治疗策略的组成部分,作为决策的桥梁。TMCS可以促进心肺功能的恢复,末端器官功能,并可能降低左心室辅助装置(LVAD)植入的手术风险。尽管改善了血液动力学和终末器官功能,这些高危患者的LVAD术后发病率可能会增加。该研究的目的是比较在HM3植入之前有和没有TMCS的患者植入Heartmate3(HM3)后的结果。方法。在这项对2015年11月至2021年10月期间所有HM3患者进行的回顾性队列研究中,比较了既往有和没有TMCS的患者。患者人口统计学,基线临床特征,实验室测试,术中变量,术后结果,从患者记录中收集不良事件.结果。在植入LVAD之前,TMCS组显示血流动力学的改善。中位TMCS持续时间为19.5(14-26)天。然而,TMCS组有更多的凝血障碍,有更多的伤口感染,神经系统并发症,与HM3植入前没有TMCS的患者相比,更多的患者接受透析。在TMCS(N=22)和非TMCS组(N=41)中,HM3植入后四年的生存率分别为80%和82%,分别。结论。接受TMCS的患者具有可接受的短期和长期生存率,并且与接受HM3而没有先前TMCS的患者相当。然而,他们有一个更复杂的术后过程。
    Objectives. Temporary mechanical circulatory support (TMCS) has become a component in the therapeutic strategy for treatment of cardiogenic shock as a bridge-to-decision. TMCS can facilitate recovery of cardiopulmonary function, end-organ function, and potentially reduce the surgical risk of left ventricular assist device (LVAD) implantation. Despite the improvements of hemodynamics and end-organ function, post-LVAD operative morbidity might be increased in these high-risk patients. The aim of the study was to compare outcomes after Heartmate 3 (HM3) implantation in patients with and without TMCS prior to HM3 implant. Methods. In this retrospective cohort study of all HM3 patients in the period between November 2015 and October 2021, patients with and without prior TMCS were compared. Patients\' demographics, baseline clinical characteristics, laboratory tests, intraoperative variables, postoperative outcomes, and adverse events were collected from patient records. Results. The TMCS group showed an improvement in hemodynamics prior to LVAD implantation. Median TMCS duration was 19.5 (14-26) days. However, the TMCS group were more coagulopathic, had more wound infections, neurological complications, and more patients were on dialysis compared with patient without TMCS prior to HM3 implantation. Survival four years after HM3 implantation was 80 and 82% in the TMCS (N = 22) and non-TMCS group (N = 41), respectively. Conclusion. Patients on TMCS had an acceptable short and long-term survival and comparable to patients receiving HM3 without prior TMCS. However, they had a more complicated postoperative course.

    城市热浪的日益频繁发生已成为人类健康的重大威胁。为定量分析热浪特征变化,调查武汉市未来热浪重现期,中国,这项研究提取了9个热浪定义,并将其分为3个死亡风险水平,以识别和分析热浪的历史观察和未来预测。使用copula函数得出热浪严重程度和持续时间的联合分布,并分析共现重现期。结果证明如下。(1)随着温室气体排放浓度的增加,热浪的严重程度加剧,热浪的发生显著增加;此外,在每个排放情景中,较长持续时间的热浪与较高的风险水平相关。(2)温室气体排放浓度的增加导致每个风险级别的热浪共现重现期明显缩短。(3)在每个排放情景下的3个风险级别中,随着热浪严重程度的加剧和持续时间的增加,热浪的共现重现期变得更长。在气候变化的影响下,针对特定区域的热浪预警系统对于决策者降低人口中热相关死亡风险至关重要,尤其是弱势群体。
    The increasingly frequent occurrence of urban heatwaves has become a significant threat to human health. To quantitatively analyze changes in heatwave characteristics and to investigate the return periods of future heatwaves in Wuhan City, China, this study extracted 9 heatwave definitions and divided them into 3 mortality risk levels to identify and analyze historical observations and future projections of heatwaves. The copula functions were employed to derive the joint distribution of heatwave severity and duration and to analyze the co-occurrence return periods. The results demonstrate the following. (1) As the concentration of greenhouse gas emissions increases, the severity of heatwaves intensifies, and the occurrence of heatwaves increases significantly; moreover, a longer duration of heatwaves correlated with higher risk levels in each emission scenario. (2) Increasing concentrations of greenhouse gas emissions result in significantly shorter heatwave co-occurrence return periods at each level of risk. (3) In the 3 risk levels under each emission scenario, the co-occurrence return periods for heatwaves become longer as heatwave severity intensifies and duration increases. Under the influence of climate change, regional-specific early warning systems for heatwaves are necessary and crucial for policymakers to reduce heat-related mortality risks in the population, especially among vulnerable groups.

    背景:这项研究得到了医学伦理委员会LDD的批准(莱顿,DenHaag,代尔夫特),方案编号P16.048和一般评估注册(ABR)编号NL56308.058.16。进一步的结果将通过同行评审的期刊和国际会议分享。
    BACKGROUND: Oocyte donation (OD) pregnancy is accompanied by a high incidence of hypertensive complications, with serious consequences for mother and child. Optimal care management, involving early recognition, optimisation of suitable treatment options and possibly eventually also prevention, is in high demand. Prediction of patient-specific risk factors for hypertensive complications in OD can provide the basis for this. The current project aims to establish the first prediction model on the risk of hypertensive complications in OD pregnancy.
    METHODS: The present study is conducted within the DONation of Oocytes in Reproduction project. For this multicentre cohort study, at least 541 OD pregnancies will be recruited. Baseline characteristics and obstetric data will be collected. Additionally, one sample of maternal peripheral blood and umbilical cord blood after delivery or a saliva sample from the child will be obtained, in order to determine the number of fetal-maternal human leucocyte antigen mismatches. Following data collection, a multivariate logistic regression model will be developed for the binary outcome hypertensive complication \'yes\' and \'no\'. The Prediction model Risk Of Bias ASsessment Tool will be used as guide to minimise the risk of bias. The study will be reported in line with the \'Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis\' guideline. Discrimination and calibration will be determined to assess model performance. Internal validation will be performed using the bootstrapping method. External validation will be performed with the \'DONation of Oocytes in Reproduction individual participant data\' dataset.
    BACKGROUND: This study is approved by the Medical Ethics Committee LDD (Leiden, Den Haag, Delft), with protocol number P16.048 and general assessment registration (ABR) number NL56308.058.16. Further results will be shared through peer-reviewed journals and international conferences.

    虽然2019年冠状病毒病(COVID-19)可能会增加镰状细胞病(SCD)患者的急性发作,这也可能改变了他们对急诊科(ED)服务的依赖。我们评估了COVID-19大流行和封锁对法国五个参考中心随访的成年SCD患者的ED就诊的影响,特别关注“高用户”(2019年访问量≥10次)。我们使用自控病例系列分析了2015年1月1日至2021年12月31日的ED访视率。在1530人中(17829次ED访问),我们观察到,在封锁期间和之后,急诊就诊人数显著减少,但效果随着时间的推移消失了.与大流行前相比,第一次封锁时,ED就诊的发生率为0.59[95%CI0.52-0.67],第二次为0.66[95%CI0.58-0.75],第三次为0.85[95%CI0.73-0.99]。高用户(4%的人,但33.7%的访问量)主要推动了第一次封锁后的减少。COVID-19封锁与急诊就诊减少有关。虽然大多数人在2021年4月之前恢复了基线利用率,但高用户的ED访问量却持续下降。了解导致高用户ED利用率下降的因素可能会为临床实践和卫生政策提供信息。
    While the coronavirus disease-2019 (COVID-19) might have increased acute episodes in people living with sickle cell disease (SCD), it may also have changed their reliance on emergency department (ED) services. We assessed the impact of the COVID-19 pandemic and lockdowns on ED visits in adult SCD people followed in five French reference centres, with a special focus on \'high users\' (≥10 visits in 2019). We analysed the rate of ED visits from 1 January 2015 to 31 December 2021, using a self-controlled case series. Among 1530 people (17 829 ED visits), we observed a significant reduction in ED visits during and after lockdowns, but the effect vanished over time. Compared to pre-pandemic, incidence rate ratios for ED visits were 0.59 [95% CI 0.52-0.67] for the first lockdown, 0.66 [95% CI 0.58-0.75] for the second and 0.85 [95% CI 0.73-0.99] for the third. High users (4% of people but 33.7% of visits) mainly drove the reductions after the first lockdown. COVID-19 lockdowns were associated with reduced ED visits. While most people returned to their baseline utilization by April 2021, high users had a lasting decrease in ED visits. Understanding the factors driving the drop in ED utilization among high users might inform clinical practice and health policy.

    背景:妊娠作为心血管压力测试。虽然许多并发症在出生后解决,妊娠合并高血压疾病的女性长期患心血管疾病(CVD)的风险增加.监测产后健康可以减少这种风险,但需要更好的方法来识别高风险妇女,以便及时进行干预。
    方法:采用定性描述性研究设计,进行了焦点小组和/或访谈,分别聘请公共贡献者和临床专业人员。通过社交媒体便利抽样招募了不同的参与者。半结构化,主持人主导的讨论探讨了当前产后评估的观点,以及将患者电子医疗数据与开发识别有CVD风险的产后妇女的数字工具联系起来的态度.参与者的观点是使用便利贴或主持人抄写员收集的,并进行了主题分析。
    结果:来自27个公共贡献者和7个临床贡献者,制定了关于产后检查期望与现实的五个主题,包括“有限资源”,\'低孕产妇健康优先级\',\'缺乏知识\',\“无效系统\”和\“新妈妈综合征\”。尽管有些担忧,所有支持数据链接,以识别产后妇女,针对心血管疾病风险较大的人群进行干预。与会者概述了数字化和风险预测的潜在好处。突出不同社区的设计和沟通需求。
    结论:英国目前的卫生系统限制导致产后护理欠佳。整合数据链接并改善孕产妇保健数据和数字工具的教育,显示出加强监测和改善未来健康的希望。在简化流程和风险预测方面获得认可,数字工具可以实现更多以人为本的护理计划,解决当前产后护理实践中的差距。
    BACKGROUND: Pregnancy acts as a cardiovascular stress test. Although many complications resolve following birth, women with hypertensive disorder of pregnancy have an increased risk of developing cardiovascular disease (CVD) long-term. Monitoring postnatal health can reduce this risk but requires better methods to identity high-risk women for timely interventions.
    METHODS: Employing a qualitative descriptive study design, focus groups and/or interviews were conducted, separately engaging public contributors and clinical professionals. Diverse participants were recruited through social media convenience sampling. Semi-structured, facilitator-led discussions explored perspectives of current postnatal assessment and attitudes towards linking patient electronic healthcare data to develop digital tools for identifying postpartum women at risk of CVD. Participant perspectives were gathered using post-it notes or a facilitator scribe and analysed thematically.
    RESULTS: From 27 public and seven clinical contributors, five themes regarding postnatal check expectations versus reality were developed, including \'limited resources\', \'low maternal health priority\', \'lack of knowledge\', \'ineffective systems\' and \'new mum syndrome\'. Despite some concerns, all supported data linkage to identify women postnatally, targeting intervention to those at greater risk of CVD. Participants outlined potential benefits of digitalisation and risk prediction, highlighting design and communication needs for diverse communities.
    CONCLUSIONS: Current health system constraints in England contribute to suboptimal postnatal care. Integrating data linkage and improving education on data and digital tools for maternal healthcare shows promise for enhanced monitoring and improved future health. Recognised for streamlining processes and risk prediction, digital tools may enable more person-centred care plans, addressing the gaps in current postnatal care practice.
