ABSTRACT
Antiphospholipid syndrome (APS) is characterized by arterial and venous thrombosis and(or) morbid pregnancy, accompanied by persistent antiphospholipid antibody (aPL) positivity. However, due to the complex pathogenesis of APS and the large individual differences in the expression of aPL profiles of patients, the problem of APS diagnosis, prognosis judgment and risk assessment may not be solved only from antibody level. It is necessary to use new technologies and multiple dimensions to explore novel APS biomarkers. The application of next generation sequencing (NGS) technology in diseases with high incidence of somatic mutations, such as genetic diseases and tumors, has been very mature. Thus, gradually understanding the research and application progress of APS by NGS technology from genome, transcriptome, epigenome and other aspects is meaningful. This article reviews the related research of NGS technology in APS, and provide more reference for the deep understanding of the APS-related screening markers and disease pathogenesis.

BACKGROUND@#The HELIOS stent is a sirolimus-eluting stent with a biodegradable polymer and titanium oxide film as the tie-layer. The study aimed to evaluate the safety and efficacy of HELIOS stent in a real-world setting.@*METHODS@#The HELIOS registry is a prospective, multicenter, cohort study conducted at 38 centers across China between November 2018 and December 2019. A total of 3060 consecutive patients were enrolled after application of minimal inclusion and exclusion criteria. The primary endpoint was target lesion failure (TLF), defined as a composite of cardiac death, non-fatal target vessel myocardial infarction (MI), and clinically indicated target lesion revascularization (TLR) at 1-year follow-up. Kaplan-Meier methods were used to estimate the cumulative incidence of clinical events and construct survival curves.@*RESULTS@#A total of 2998 (98.0%) patients completed the 1-year follow-up. The 1-year incidence of TLF was 3.10% (94/2998, 95% closed interval: 2.54-3.78%). The rates of cardiac death, non-fatal target vessel MI and clinically indicated TLR were 2.33% (70/2998), 0.20% (6/2998), and 0.70% (21/2998), respectively. The rate of stent thrombosis was 0.33% (10/2998). Age ≥60 years, diabetes mellitus, family history of coronary artery disease, acute myocardial infarction at admission, and device success were independent predictors of TLF at 1 year.@*CONCLUSION@#The 1-year incidence rates of TLF and stent thrombosis were 3.10% and 0.33%, respectively, in patients treated with HELIOS stents. Our results provide clinical evidence for interventional cardiologists and policymakers to evaluate HELIOS stent.@*CLINICAL TRIAL REGISTRATION@#ClinicalTrials.gov, NCT03916432.

Hepatocelluar carcinoma presenting as a biliary duct tumor thrombus is a relatively rare entity, with poor prognosis. The primary clinical manifestation of this disease is obstructive jaundice, which can often be misdiagnosed. A 59-year-old female patient was admitted with sudden onset of abdominal pain. Laboratory tests suggested obstructive jaundice, and enhanced magnetic resonance imaging of the upper abdomen did not show obvious biliary dilatation. Endoscopic ultrasound and endoscopic retrograde cholangiopancreatography suggested an occupying lesion in the upper bile duct. SpyGlass and biopsy finally confirmed hepatocellular carcinoma with right hepatic duct tumor thrombus hemorrhage. The SpyGlass Direct Visualization System, as an advanced biliary cholangioscopy device, showed the advantages of single-person operation as well as easy access to and visualization of the lesion.

BACKGROUND: Vena cava (VC) involvement in kidney tumors occurs in 4 to 10% of cases, and is associated with a higher mortality. Nephrectomy with thrombectomy of the VC, performed by a multidisciplinary team, improves survival. Aim: To report a series of consecutive nephrectomies with caval thrombectomy performed in an academic center. PATIENTS AND METHODS: We report 32 patients with cT3b and 3c renal tumors, who underwent radical nephrectomy with VC thrombectomy between 2001 and 2021. A descriptive analysis of clinical, surgical and pathological variables was performed. Overall survival (OS) and cancer-specific survival (CSS) was calculated using Kaplan-Meier curves. Results: The mean tumor size was 9.7 cm. According to Mayo classification 3/32 (9%) patients had a type I thrombus, 10/32 (31%) had a type II thrombus, 8/32 (25%) had a type III thrombus, and 5/32 (16%) had a type IV thrombus. The mean bleeding was 2000 cc. There was one intraoperative death. Nineteen percent of patients had complications >= 3 according to Clavien-Dindo classification. Reoperations occurred in 9%. Pre and postoperative creatinine levels were 1.17 and 1.91 mg/dl respectively (p < 0.01). Pre and postoperative Hematocrit levels were 47.9 and 31% respectively (p = 0.02). Sixty six percent of tumors were clear cell renal cancer, 9% were papillary and 3% were chromophobic. Mean OS was 10 months. Two-year SCE was 40%. CONCLUSIONS: Our results are similar to those reported elsewhere. Despite being an unusual pathology, the surgical technique has been improving, thanks to the multidisciplinary work of urologists and surgeons.

OBJECTIVE@#To observe preventive effect of Caprini based thrombosis risk evaluation model on venous thromboembolism (VTE) after total knee replacement (TKA).@*METHODS@#Totally 257 TKA patients were admitted from May 2017 to December 2021 were selected. They were divided into conventional intervention strategies (121 patients in control group) and intervention strategies based on Caprini thrombosis risk evaluation model (136 patients in observation group), based on whether Caprini thrombosis risk evaluation model was introduced in May 2019. In normal gourp, there were 79 males and 42 females aged from 50 to 78 years old with an average of (63.10±11.86) years old;body mass index (BMI) ranged from 19 to 32 with an average of (25.21±4.95) kg/m2;55 patients on the left side and 66 on the right side. In observation group, there were 81 males and 55 females aged from 50 to 78 years old with an average of (64.35±10.54) years old;BMI ranged from 19 to 32 with an average of (24.43±5.18) kg/m2;87 patients on the left side and 49 on the right side. The incidence of VTE, visual analogue scale (VAS), Hospital for Special Surgery (HSS) score, affected limb swelling, mean velocity(Vm), peak velocity (PV), D-dimer (D-D), prothrombin time(PT), and incidence of complications were analyzed and compared.@*RESULTS@#The incidence of VTE in observation group was 1.47%(2/136), and 9.09%(11/121) in control group, and there was statistically difference between two groups (χ2=6.976, P=0.008). At 7 days after operation, VAS, HSS score and the difference in circumference of the affected limb in observation group were significantly better than those in control group, and had statistically differences (P<0.05). Blood flow Vm and PV levels between two groups were significantly increased (P<0.001), and blood flow Vm and PV levels in observation group were significantly higher than those in control group on the 7th day after operation, and had differences (P<0.001). The serum D-D level in observation group was significantly lower than that of in control group on the 7th day after operation, and PT level was significantly higher than that of in control group, and had difference(P<0.05). There was no difference in total incidence of complications between two groups (χ2=4.488, P=0.034).@*CONCLUSION@#Intervention strategy based on caprini thrombus risk evluation model could effectively reduce incidence of VTE and complications in TKA patients, improve swelling, hemodynamics and coagulation function of the affected limbs, and contribute to recovery of knee joint function.

Abstract Since the coronavirus pandemic set in in Spain in March 2020, a noteworthy increase in the incidence of acute limb ischemia (ALI) has been observed. It has been recently discovered that SARS-CoV 2 may lead to ALI secondary to arterial thrombosis. Elevation of D-dimer (DD) in patients with coronavirus infection (COVID-19) indicates that a hypercoagulable state causes acute arterial thrombosis. A remarkably high DD elevation has been reported to be a poor prognosis factor in COVID-19. The ways in which SARS-CoV 2 results in arterial thrombosis may be multiple. On the other hand, surgical revascularization for ALI is associated with poor outcomes in COVID-19 patients, probably in relation to hypercoagulability. Here, we describe two ALI cases in patients who required urgent surgical treatment for limb salvage and were positive for the novel coronavirus infection (COVID 19).
Resumo Desde que a pandemia pelo novo coronavírus se estabeleceu na Espanha, em março de 2020, um aumento notável da incidência de isquemia aguda de membros foi observado. Recentemente, descobriu-se que o coronavírus 2 causador da síndrome respiratória aguda grave (SARS-CoV-2) pode ocasionar isquemia aguda de membros secundária à trombose arterial. A elevação do D-dímero em pacientes acometidos pela doença do novo coronavírus (COVID-19) indica o estado de hipercoagulabilidade como causa da trombose arterial aguda. Vale destacar que a alta elevação do D-dímero foi relatada como um fator de prognóstico reservado na COVID-19. Há diversas maneiras pelas quais o SARS-CoV-2 pode resultar em trombose arterial. Em pacientes com COVID-19, a revascularização cirúrgica para isquemia aguda de membros está associada a desfechos desfavoráveis, provavelmente relacionados a hipercoagulabilidade. Descrevemos dois casos de isquemia aguda de membros de pacientes que necessitaram de tratamento cirúrgico de urgência para salvamento de membro e que haviam testado positivo para COVID-19.

ABSTRACT Objectives: The most common disease of anus is hemorrhoids. The definition of external hemorrhoids suggests the acute phase, often characterized by thrombosis or edema. External thrombosed hemorrhoid is a specific complication. In this study, we aimed to investigate the effects of different platelet parameters in the presence of internal or external thrombosed hemorrhoids. Methods: Patients examined were divided into two groups: Group 1: Thrombosed hemorrhoids group (THG), Group 2: Hemorrhoidectomy group (HG). Demographic and clinical data were identified. In terms of laboratory findings, preoperative hemoglobin, hematocrit and all platelet parameters were recorded. Main results: Fifty-two patients in THG, and 75 patients in HG were included in the study. In female sex and young age group, the risk of developing thrombosed hemorrhoids was statistically significant (p= 0.029, p= 0.039, respectively). When the platelet parameters were evaluated; while PDW was higher in THG (p= 0.008), any significant difference could not found in all other values (p> 0.05). Thrombosed hemorrhoids were mostly (59.25%) found to be located in the left laterodorsal part of anus. Conclusion: Internal hemorrhoids are frequently seen in the ages of 45-65 with similar rates in both sexes, while external thrombosed hemorrhoids occur at a younger age (<45) and more often in women. Comparing in terms of platelet indexes, PDW value was found to be significantly higher in THG. In young people, thrombosed hemorrhoids may develop more frequently, as the connective tissue that forms the anal pads is not loose enough to form an internal hemorrhoid, as more seen in older patients.
RESUMO Objetivos: A doença anal mais comum são as hemorróidas. A definição de hemorróidas externas sugere a fase aguda, muitas vezes caracterizada por trombose ou edema. A hemorroida externa trombosada é uma complicação específica. Neste estudo, objetivamos investigar os efeitos de diferentes parâmetros plaquetários na presença de hemorróidas trombosadas internas ou externas. Métodos: Os pacientes examinados foram divididos em dois grupos: Grupo 1, Grupo de Hemorróidas Trombosadas (GHT); Grupo 2, Grupo de hemorroidectomia (GH). Os dados demográficos e clínicos foram identificados. Em termos de achados laboratoriais, a hemoglobina pré-operatória, o hematócrito e todos os parâmetros plaquetários foram registrados. Resultados principais: Cinquenta e dois pacientes em GHT e 75 pacientes em GH foram incluídos no estudo. No sexo feminino e na faixa etária jovem, o risco de desenvolver hemorróidas trombosadas foi estatisticamente significativo (p = 0,029, p = 0,039, respectivamente). Os parâmetros plaquetários avaliados mostraram que, enquanto a Amplitude de Distribuição de Plaquetas (PDW, do inglês platelet distribution width) foi maior no GHT (p = 0,008), nenhuma diferença significativa foi encontrada para todos os outros valores (p > 0,05). A maioria das hemorróidas trombosadas (59,25%) localizava-se na região lateral-dorsal esquerda do ânus. Conclusão: As hemorróidas internas são frequentemente vistas nas idades de 45 a 65 anos com taxas semelhantes em ambos os sexos, enquanto as hemorróidas externas trombosadas ocorrem em uma idade mais jovem (<45) e mais frequentemente em mulheres. Comparando em termos de índices de plaquetas, foi observado que o valor de PDW foi significativamente maior no GHT. Em pessoas jovens, as hemorróidas trombosadas podem se desenvolver com mais frequência, pois o tecido conjuntivo que forma as almofadas anais não é flácido o suficiente para formar uma hemorroida interna, como ocorre com mais frequência em pacientes mais velhos.

Abstract Background Left ventricular apical thrombus (AT) is generally associated with ischemic and non-ischemic cardiomyopathies. The thrombo-inflammatory process plays an important role in the pathophysiology of acute coronary syndromes and post-myocardial thromboembolic complications. Mean platelet volume (MPV) has been linked to poor prognosis following myocardial infarction. Recently, platelet-to-lymphocyte ratio (PLR) has emerged as a new marker of worse outcomes linking inflammation and thrombosis. Objective We aimed to investigate the prognostic significance of the marker - mean platelet volume to lymphocyte ratio (MPVLR) in patients with AT. Methods Fifty-six patients with left ventricular AT after an anterior myocardial infarction and 51 patients without left ventricular AT after an anterior myocardial infarction were enrolled in this study retrospectively. Admission MPVLR was compared between the two groups. Logistic regression analysis was carried out to identify whether MPVLR is an independent predictor of AT. The receiver operating curve (ROC) analysis was used to show the optimal cut-off for MPVLR to predict AT. P values less than 0.05 were considered statistically significant. Results Age, gender, frequency of diabetes mellitus, hypertension and atrial fibrillation, and ejection fraction values did not differ between the groups. MPVLR was higher in patients with AT than patients without AT (7.91±2.5 vs 5.1±2.1, p<0.001). ROC analysis revealed moderate diagnostic value in predicting the presence of AT with a MPVLR cut-off > 4.75 (82.1% sensivity and 70.2% specifity (area under the curve=0.811, 95% confidence interval [CI]: 0.731-0.891, p<0.001). MPVLR was found to be an independent risk factor for the formation of AT (B:0.441, p.0.001). Conclusion MPVLR is a simple, cheap and easily accessible test that can predict left ventricular AT formation. (Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0)

Abstract Objective: To examine the relationship between the left atrial (LA) thrombus presence and the epicardial adipose tissue (EAT) thickness. Methods: Three hundred and twelve consecutive rheumatic mitral valve stenosis (RMVS) patients with mitral valve area (MVA) < 2 cm2 were included in this cross-sectional study. Patients were divided into two groups, those with and those without LA thrombus. Routine biochemical analysis and electrocardiographic examinations were carried out. EAT was measured using transthoracic echocardiography. Results: LA thrombus was determined in 84 (26.9%) RMVS patients. In echocardiographic examinations, higher mean gradient and LA diameter as well as lower MVA were found in the group with LA thrombus (P<0.001). In this group, higher C-reactive protein (CRP) and EAT values were also determined (P<0.001). There was significant correlation between EAT and MVA, CRP, LA appendage peak flow velocity, LA anteroposterior diameter, and mean gradient (P<0.001). Higher EAT values were identified as independently associated with the presence of LA thrombus (odds ratio 59.5; 95% confidence interval 12.1-290.10; P<0.001). Conclusion: Transthoracic echocardiography, routinely used in patients with RMVS, can measure EAT to determine patients who are under risk for thrombus.
