  • 文章类型: Journal Article
    胃壁内血肿是一种非常罕见的疾病。它可能是由于消化性溃疡疾病引起的凝块性胃出血而发生的,或者创伤后,口服抗凝治疗和出血性疾病。通常怀疑有消化道出血的症状,如呕血,黑便和便血,并通过内窥镜检查检测到。在极少数情况下,患者无症状或出现非相关症状,可通过计算机断层扫描诊断。在这种情况下,我们报告了一名低血压患者在腹部超声检查中发现的胃壁内血肿,该患者是在从高处滑落后进入急诊科的。
    结论:记住FAST超声在检查五个方面很重要,上胃出血出现低回声,使超声评估必不可少。
    Gastric intramural haematoma is a very infrequent condition. It can occur due to clotted gastric haemorrhage as a result of peptic ulcer disease, or following trauma, oral anticoagulant therapy and bleeding disorders. It is usually suspected with the symptoms of gastrointestinal haemorrhage such as haematemesis, melena and haematochezia, and detected by endoscopy. In rare cases, the patient is asymptomatic or presents with non-related symptoms and can diagnosed by computerised tomography. In this case, we report the detection of a gastric intramural haematoma during abdominal ultrasonography in a hypotensive patient who was admitted to the emergency department after sliding and falling from a height.
    CONCLUSIONS: It is crucial to remember that FAST ultrasound is important in examining five areas, and epigastric bleeding appears hypoechoic, making ultrasound evaluation essential.

    胰腺炎是登革热的一种非常罕见但严重的眼部并发症,目前在印度部分地区是一个重大的健康问题。它是一种化脓性炎症,涵盖了地球的所有结构(脉络膜,视网膜,玻璃体液,水性流体,角膜,巩膜,和结膜)以及周围的眼眶和眼眶结构。这个病例系列突出了三名诊断为登革热的患者中全眼炎的发生,年龄分别为35岁、50岁和75岁。尽管积极的医疗管理,包括静脉注射抗生素,由于病情严重,患者最终被安排进行内脏手术。医疗保健提供者必须意识到登革热病例中潜在的眼部并发症,并及时诊断。虽然登革热的眼部受累很少,本系列病例强调认识登革热患者眼部表现的重要性,早期诊断和及时干预可预防严重并发症。
    Panophthalmitis is an exceptionally rare but severe ocular complication of dengue fever, which is currently a significant health concern in parts of India. It is a purulent inflammation encompassing all structures of the globe (choroid, retina, vitreous fluid, aqueous fluid, cornea, sclera, and conjunctiva) along with surrounding orbital and periorbital structures. This case series highlights the occurrence of panophthalmitis in three patients diagnosed with dengue, who were aged 35, 50, and 75 years. Despite aggressive medical management, including intravenous antibiotics, the patients were ultimately scheduled for evisceration surgery due to the extreme severity of the condition. Healthcare providers must be aware of the potential ocular complications in dengue cases and diagnose them promptly. While ocular involvement in dengue is rare, this case series emphasizes the importance of recognizing ocular manifestations in dengue patients, as early diagnosis and prompt intervention can prevent severe complications.

    背景:运动型马的运动性肺出血(EIPH)的特征是剧烈运动后气管支气管树中存在来自肺部的血液。尽管EIPH在马匹中的患病率很高,主要病因尚不清楚。编码CD39和CD39L1(分别为ENTPD1和ENTPD2)的基因中的变异体先前被报道为涉及EIPH发病机理的潜在遗传原因。然而,这些变异体在止血功能中的作用尚不清楚.
    结果:为了研究EIPH与ENTPD1(rs1152296272,rs68621348和rs68621347)和ENTPD2基因(rs782872967)中错义变体之间的关联,对76匹诊断为EIPH的纯种马和56匹通过气管-支气管内窥镜检查无EIPH临床体征的纯种马(对照组)进行基因分型。rs1152296272和rs68621347变体是连接的,这解释了为什么在所有马匹中都发现了相同的结果。大约96%和95%的EIPH和对照马,分别,携带这些变体的至少一个非参考等位基因。相比之下,100%的对照马和96%的EIPH马对于rs68621348变体的参考等位基因是纯合的。在EIPH组中,对于rs782872967变体的非参考等位基因,1.5%的马是纯合子,24%是杂合的。在对照组中,仅在杂合子中观察到该变体的非参考等位基因(16%).对于任何变体,组间没有显著差异。
    结论:先前在编码CD39和CD39L1酶的基因中描述的变体在研究群体中高度存在。然而,在这项研究中,在纯种马中没有发现EIPH的发生和这些变异的存在之间的关联.
    BACKGROUND: Exercise-induced pulmonary haemorrhage (EIPH) in athletic horses is characterized by the presence of blood from the lungs in the tracheobronchial tree after intense exercise. Despite the high prevalence of EIPH in horses, the primary aetiology remains unknown. Variants in the genes encoding CD39 and CD39L1 (ENTPD1 and ENTPD2, respectively) were previously reported as potential genetic causes involved in EIPH pathogenesis. However, the role of these variants in haemostatic functions is unknown.
    RESULTS: To investigate the association between EIPH and missense variants in the ENTPD1 (rs1152296272, rs68621348, and rs68621347) and ENTPD2 genes (rs782872967), 76 Thoroughbred horses diagnosed with EIPH and 56 without clinical signs of EIPH (control group) by trachea-bronchial endoscopy were genotyped. The rs1152296272 and rs68621347 variants were linked, which explained why the same results were found in all horses. Approximately 96% and 95% of the EIPH and control horses, respectively, carried at least one nonreference allele for these variants. In contrast, 100% of the control horses and 96% of the EIPH horses were homozygous for the reference allele for the rs68621348 variant. In the EIPH group, 1.5% of the horses were homozygotes and 24% were heterozygous for the nonreference allele of the rs782872967 variant. In the control group, the nonreference allele of this variant was observed only in heterozygotes (16%). There were no significant differences between groups for any of the variants.
    CONCLUSIONS: The variants previously described in the genes encoding the CD39 and CD39L1 enzymes were highly present in the studied population. However, no association was found between the occurrence of EIPH and the presence of these variants in Thoroughbred horses in this study.

    本文旨在概述当前的实践,并研究骨科创伤出血的现代管理方面有希望的新进展。几十年来,许多院前和围手术期出血控制策略和技术已被临床医生使用。然而,我们对这些做法的理解和利用仍在不断完善和优化。本文特别关注与创伤中的复苏和凝血相关的问题。我们研究了导致创伤患者凝血功能障碍的复杂机制,以及氨甲环酸在限制失血方面的转化作用。我们还探索了一些新兴技术,如血管内干预和凝块稳定敷料和设备,这些技术可能会对未来产生重大影响。
    This paper aims to outline current practices and examine promising new advancements in the modern management of haemorrhage in orthopaedic trauma. Many prehospital and perioperative haemorrhage control strategies and techniques have been available to clinicians for multiple decades, yet our understanding and utilisation of these practices continues to be refined and optimised. There is a particular focus in this article on issues related to resuscitation and coagulation in trauma. We examine the complex mechanisms that lead to coagulopathy in trauma patients as well as the transformative effect tranexamic acid has had in limiting blood loss. We also explore some emerging technologies such as endovascular interventions and clot-stabilising dressings and devices that are likely to have a significant impact going forward.

    肝硬化患者处于平衡止血的微妙状态,并且有发生出血和血栓并发症的风险。常规止血试验无法预测这些患者的出血和血栓形成。我们旨在探讨旋转血栓弹性测量(ROTEM)在预测肝硬化患者出血和血栓事件中的作用。
    我们对两家大都市医院的肝硬化患者进行了一项前瞻性队列研究。所有患者均接受ROTEM分析,然后随访以记录任何出血和血栓事件。进行单变量和多变量逻辑回归分析以探讨与出血和血栓形成事件的关系。
    招募的162名患者中有19名在ROTEM分析的一年内经历了出血事件。在单变量分析中,在发生出血事件的患者中,使用EXTEM和INTEM测试的最大凝块硬度(MCF)显着降低,与那些没有(50毫米vs.57毫米,p<0.01和48mmvs.54毫米,p分别<0.01)。此外,在单变量分析中,出血组INTEM试验中的凝血时间(CT)延长(214svs.198s,p=0.01)。在多变量分析中,只有MCFEX是出血事件的重要预测因子.相比之下,未发现ROTEM参数与1年内血栓形成之间的关联.
    ROTEM可能为预测肝硬化患者未来的出血事件提供有用的工具。需要更大规模的研究来进一步验证这一发现并探索其在临床实践中的应用。
    UNASSIGNED: Patients with cirrhosis of the liver are in a delicate state of rebalanced haemostasis and are at risk of developing both bleeding and thrombotic complications. Conventional haemostatic tests are unable to predict bleeding and thrombosis in these patients. We aimed to explore the role of Rotational Thromboelastometry (ROTEM) in predicting bleeding and thrombotic events in patients with cirrhosis.
    UNASSIGNED: We conducted a prospective cohort study of patients with cirrhosis at two metropolitan hospitals. All patients underwent ROTEM analysis and were then followed to record any bleeding and thrombotic events. Univariate and multivariate logistic regression analyses were performed to explore associations with bleeding and thrombotic events.
    UNASSIGNED: Nineteen of the 162 patients recruited experienced a bleeding event within one year of ROTEM analysis. On univariate analysis, maximum clot firmness (MCF) using both EXTEM and INTEM tests was significantly reduced in patients who had a bleeding event, compared to those who did not (50 mm vs. 57 mm, p < 0.01 and 48 mm vs. 54 mm, p < 0.01, respectively). In addition, on univariate analysis, clotting time (CT) in the INTEM test was prolonged in the bleeding group (214 s vs. 198 s, p = 0.01). On multivariate analysis, only MCFEX was a significant predictor of bleeding events. In contrast, there was no association found between ROTEM parameters and development of thrombosis within a one-year period.
    UNASSIGNED: ROTEM may provide a useful tool in predicting future bleeding events in patients with cirrhosis. Larger studies are required to further validate this finding and explore its application in clinical practice.

    背景:心脏手术后出血是常见且严重的,然而,在了解有经验的重症监护护士如何识别和应对此类并发症方面仍然存在差距.
    目的:描述有经验的重症监护病房护士处理心脏手术后出血的临床决策。
    方法:这项定性研究采用了识别启动决策模型作为其理论框架。来自四个成人重症监护病房的39名经验丰富的护士参加了基于关键决策方法的半结构化访谈。访谈探讨了他们在出血情况下的临床判断和决定,并通过量纲分析对数据进行分析,扎根理论的替代方案。
    结果:参与者对心脏手术后出血保持一致的警惕,通过与失血和胸腔引流相关的出血维度和关注血容量减少的影响的低血容量维度来认识它。这些维度组织了他们对出血类型的理解(即,正常,medical,外科,填塞)和必要的行动。他们的决策包括监测出血,找出原因,止血,稳定血液动力学并支持患者和家人。参加者还根据具体情况调整行动,包括当地的做法,专业自主权,跨专业动态和资源可用性。
    结论:护士的决策是由他们的个人属性决定的,患者的状况和背景情况,强调他们的专业知识和在预测行动和适应不同条件方面的关键作用。可操作性的概念成为解释他们决策的中心维度,定义为在情况的可能性和约束下实施针对特定目标的行动的能力。
    结论:本研究强调需要不断更新护理方案以与当前证据保持一致,并需要采取质量改进措施以缩小现有的实践差距。进一步探索可操作性的概念,制定以适应性为重点的教育计划,了解决策的复杂性对于告知护理教育和决策支持系统至关重要。
    BACKGROUND: Bleeding following cardiac surgery is common and serious, yet a gap persists in understanding how experienced intensive care nurses identify and respond to such complications.
    OBJECTIVE: To describe the clinical decision-making of experienced intensive care unit nurses in addressing bleeding after cardiac surgery.
    METHODS: This qualitative study adopted the Recognition-Primed Decision Model as its theoretical framework. Thirty-nine experienced nurses from four adult intensive care units participated in semi-structured interviews based on the critical decision method. The interviews explored their clinical judgements and decisions in bleeding situations, and data were analysed through dimensional analysis, an alternative to grounded theory.
    RESULTS: Participants maintained consistent vigilance towards post-cardiac surgery bleeding, recognizing it through a haemorrhagic dimension associated with blood loss and chest drainage and a hypovolemic dimension focusing on the repercussions of reduced blood volume. These dimensions organized their understanding of bleeding types (i.e., normal, medical, surgical, tamponade) and necessary actions. Their decision-making encompassed monitoring bleeding, identifying the cause, stopping the bleeding, stabilizing haemodynamic and supporting the patient and family. Participants also adapted their actions to specific circumstances, including local practices, professional autonomy, interprofessional dynamics and resource availability.
    CONCLUSIONS: Nurses\' decision-making was shaped by their personal attributes, the patient\'s condition and contextual circumstances, underscoring their expertise and pivotal role in anticipating actions and adapting to diverse conditions. The concept of actionability emerged as the central dimension explaining their decision-making, defined as the capability to implement actions towards specific goals within the possibilities and constraints of a situation.
    CONCLUSIONS: This study underscores the need for continual updates to care protocols to align with current evidence and for quality improvement initiatives to close existing practice gaps. Exploring the concept of actionability further, developing adaptability-focused educational programmes, and understanding decision-making intricacies are crucial for informing nursing education and decision-support systems.

    微创经皮肾镜取石术(mini-PCNL)保持与标准PCNL相似的结石清除率,同时减少失血。出血是PCNL手术后可能出现的复杂而严重的并发症。假性动脉瘤(PA)是一种罕见的延迟出血问题,PCNL后影响不到1%的患者。对于严重的PCNL后出血,最有效的治疗方法是超选择性肾血管造影栓塞术(SRAE)。但它可能在一些患者失败,需要额外的手术干预。这份报告详细介绍了一名男性患者的情况,55岁,谁经历了严重出血四次,并在PCNL后接受了三次SRAE手术和一次腹腔镜手术。在血管造影的前两次尝试中,由于动脉痉挛和小的,最初没有发现肾动脉假性动脉瘤的存在。未发育的病变。本病例报告旨在提高对微小假性动脉瘤的认识,强调避免疏忽对提高栓塞成功率的重要性。
    Minimally invasive percutaneous nephrolithotomy (mini-PCNL) maintains a stone clearance rate similar to standard PCNL while reducing blood loss. Bleeding is a complex and serious complication that can arise after PCNL surgery. Pseudoaneurysm (PA) is an uncommon type of delayed bleeding problem, which affects less than 1% of patients after PCNL. The most effective treatment for severe post-PCNL hemorrhage is super-selective renal angiographic embolization (SRAE), but it can fail in some patients and require additional surgical intervention. This report details the case of a male patient, 55 years old, who experienced severe bleeding four times and had three SRAE procedures and one laparoscopic procedure after PCNL. The presence of a renal artery pseudoaneurysm was not initially identified during the first two attempts of angiography due to arterial spasm and a small, undeveloped lesion. This case report is intended to enhance awareness of tiny pseudoaneurysms, emphasizing the importance of avoiding oversight to improve the success rate of embolization.

    非洲猪瘟(ASF)是一种破坏性疾病,对全球猪肉行业产生重大影响。ASF病毒(ASFV)是一种非常复杂的病原体,Asfaviridae家族的唯一成员,它通过感染骨髓细胞和淋巴细胞凋亡诱导宿主的免疫抑制状态。此外,出血是猪ASFV感染的另一个主要致病作用,与内皮细胞感染有关,以及旁观者单核细胞和巨噬细胞内促炎细胞因子上调引起的该细胞群的活化和结构变化。关于ASFV产生的蛋白质的作用的知识仍然存在许多空白,这与生产安全有效的疫苗来对抗这种疾病的困难有关,尽管在过去的几年中,很少有候选人被批准在东南亚使用。
    African swine fever (ASF) is a devastating disease with a high impact on the pork industry worldwide. ASF virus (ASFV) is a very complex pathogen, the sole member of the family Asfaviridae, which induces a state of immune suppression in the host through infection of myeloid cells and apoptosis of lymphocytes. Moreover, haemorrhages are the other main pathogenic effect of ASFV infection in pigs, related to the infection of endothelial cells, as well as the activation and structural changes of this cell population by proinflammatory cytokine upregulation within bystander monocytes and macrophages. There are still many gaps in the knowledge of the role of proteins produced by the ASFV, which is related to the difficulty in producing a safe and effective vaccine to combat the disease, although few candidates have been approved for use in Southeast Asia in the past couple of years.

    背景:目前缺乏证据证明Andexanetα和四因子凝血酶原复合物浓缩物(4F-PCC)在直接口服抗凝剂(DOAC)的抗凝逆转中的相对有效性。我们系统评价的主要目的是验证哪种药物在降低短期全因死亡率方面更有效。次要目的是确定两种恢复策略中哪一种受血栓栓塞事件的影响较小。
    方法:进行系统评价和荟萃分析。
    结果:在系统评价和定量综合中分析了22项研究。在全因短期死亡率中,Andexanetα在RCT和PSM中显示出0.71的风险比(RR)(95%CI0.37-1.34),与4F-PCC相比(I2=81%)。考虑到回顾性研究,合并的RR对于共同效应模型为0.84(95%CI0.69-1.01),对于随机效应模型为0.82(95%CI0.63-1.07)(I2=34.2%).关于血栓栓塞事件的发生率,对于RCT和PSM,共同效应和随机效应模型的RR为1.74(95%CI1.09-2.77),和1.71(95%CI1.01-2.89),分别,与4F-PCC相比,Andexanetα(I2=0%)。考虑到回顾性研究,合并的RR对于共同效应模型为1.21(95%CI0.87-1.69),对于随机效应模型为1.18(95%CI0.86-1.62)(I2=0%).
    结论:考虑到大量的回顾性和对照研究,Andexanetα在死亡率方面没有显示出超过4F-PCC的统计学显著优势。仅在对照研究的分析中,Andexanetα与血栓栓塞事件的风险增加相关。
    背景:PROSPERO:系统评价的国际前瞻性注册,2024,CRD42024548768。
    BACKGROUND: There is currently a lack of evidence for the comparative effectiveness of Andexanet alpha and four-factor prothrombin complex concentrate (4F-PCC) in anticoagulation reversal of direct oral anticoagulants (DOACs). The primary aim of our systematic review was to verify which drug is more effective in reducing short-term all-cause mortality. The secondary aim was to determine which of the two reverting strategies is less affected by thromboembolic events.
    METHODS: A systematic review and meta-analysis was performed.
    RESULTS: Twenty-two studies were analysed in the systematic review and quantitative synthesis. In all-cause short-term mortality, Andexanet alpha showed a risk ratio (RR) of 0.71(95% CI 0.37-1.34) in RCTs and PSMs, compared to 4F-PCC (I2 = 81%). Considering the retrospective studies, the pooled RR resulted in 0.84 (95% CI 0.69-1.01) for the common effects model and 0.82 (95% CI 0.63-1.07) for the random effects model (I2 = 34.2%). Regarding the incidence of thromboembolic events, for RCTs and PSMs, the common and the random effects model exhibited a RR of 1.74 (95% CI 1.09-2.77), and 1.71 (95% CI 1.01-2.89), respectively, for Andexanet alpha compared to 4F-PCC (I2 = 0%). Considering the retrospective studies, the pooled RR resulted in 1.21 (95% CI 0.87-1.69) for the common effects model and 1.18 (95% CI 0.86-1.62) for the random effects model (I2 = 0%).
    CONCLUSIONS: Considering a large group of both retrospective and controlled studies, Andexanet alpha did not show a statistically significant advantage over 4F-PCC in terms of mortality. In the analysis of the controlled studies alone, Andexanet alpha is associated with an increased risk of thromboembolic events.

    目的:接受脑脊液分流手术的婴儿面临着一种罕见的并发症,我们建议将其重命名为“婴儿分流后广泛出血”(WHIPS),以更好地捕捉这种特殊的现象。我们的目标是分析WHIPS发展的危险因素,并提供这些出血的详细神经放射学描述。
    方法:在2008年9月至2021年1月期间,使用搜索词“分流”和/或“导管”和/或“引流”和/或“脑室腹膜”和/或“VP”搜索放射学信息系统(RIS)。为符合纳入标准的每位患者编制临床数据。三名放射科医生对纳入的病例进行了WHIPS的检查,并计算了双额肌比率并记录了出血量,形态学,位置和叶状分布。
    结果:51例患者符合纳入标准,8名WHIPS患者和43名对照。术后头围较大与WHIPS之间存在统计学上的显着相关性(p=0.04)。WHIPS与出血性脑积水和感染后脑积水相关(p=0.009)。在皮质-皮质下区域发现了WHIPS,脑室周围白质,和深白质。出血要么是点状的,卵球形或汇合。出血从单一到无数。
    结论:WHIPS是婴儿群体特有的一种罕见且未被认可的脑脊液分流并发症。我们假设深部和浅表髓质静脉出血是与颅内流体动力学紊乱有关的潜在机制,由于蛛网膜颗粒不发达和颅骨顺从性,颅内流体动力学紊乱在婴儿人群中加剧。
    OBJECTIVE: Infants undergoing CSF shunting procedures face a rare complication which we propose to rename \"Widespread Haemorrhages in Infants Post-Shunting\" (WHIPS) to better capture this unique phenomenon specific to infants undergoing CSF diversion. Our objective is to analyse the risk factors for WHIPS development and provide a detailed neuroradiological description of these haemorrhages.
    METHODS: A radiology information system (RIS) was searched using the search terms \"shunt\" and/or \"catheter\" and/or \"drain\" and/or \"ventriculoperitoneal\" and/or \"VP\" between September 2008 to January 2021 for patients < 12 months of age. Clinical data was compiled for each patient meeting the inclusion criteria. Included cases were reviewed by three radiologists for the presence of WHIPS with calculation of the bifrontal ratio and documenting haemorrhage number, morphology, location and lobar distribution.
    RESULTS: 51 patients met inclusion criteria, 8 WHIPS patients and 43 controls. There was a statistically significant correlation between a larger post-op head circumference and WHIPS (p = 0.04). WHIPS was associated with post-haemorrhagic hydrocephalus and post-infectious hydrocephalus (p = 0.009). WHIPS were identified in the cortico-subcortical regions, periventricular white matter, and deep white matter. Haemorrhages were either punctate, ovoid or confluent. Haemorrhages ranged from single to innumerable.
    CONCLUSIONS: WHIPS represent a rare and under-recognised complication of CSF shunting unique to the infantile population. We postulate deep and superficial medullary venous haemorrhage as an underlying mechanism related to disordered intracranial hydrodynamics which are exacerbated in the infantile population due to underdeveloped arachnoid granulations and a compliant skull.
